The Importance and Role of Biostatistics in Clinical Research
“A substantive, thorough, sophisticated literature review is a precondition for doing substantive, thorough, sophisticated research”. Boote and Baile 2005
Authors of manuscripts treat writing a literature review as a routine work or a mere formality. But a seasoned one knows the purpose and importance of a well-written literature review. Since it is one of the basic needs for researches at any level, they have to be done vigilantly. Only then the reader will know that the basics of research have not been neglected.

The aim of any literature review is to summarize and synthesize the arguments and ideas of existing knowledge in a particular field without adding any new contributions. Being built on existing knowledge they help the researcher to even turn the wheels of the topic of research. It is possible only with profound knowledge of what is wrong in the existing findings in detail to overpower them. For other researches, the literature review gives the direction to be headed for its success.
The common perception of literature review and reality:
As per the common belief, literature reviews are only a summary of the sources related to the research. And many authors of scientific manuscripts believe that they are only surveys of what are the researches are done on the chosen topic. But on the contrary, it uses published information from pertinent and relevant sources like
- Scholarly books
- Scientific papers
- Latest studies in the field
- Established school of thoughts
- Relevant articles from renowned scientific journals
and many more for a field of study or theory or a particular problem to do the following:
- Summarize into a brief account of all information
- Synthesize the information by restructuring and reorganizing
- Critical evaluation of a concept or a school of thought or ideas
- Familiarize the authors to the extent of knowledge in the particular field
- Encapsulate
- Compare & contrast
By doing the above on the relevant information, it provides the reader of the scientific manuscript with the following for a better understanding of it:
- It establishes the authors’ in-depth understanding and knowledge of their field subject
- It gives the background of the research
- Portrays the scientific manuscript plan of examining the research result
- Illuminates on how the knowledge has changed within the field
- Highlights what has already been done in a particular field
- Information of the generally accepted facts, emerging and current state of the topic of research
- Identifies the research gap that is still unexplored or under-researched fields
- Demonstrates how the research fits within a larger field of study
- Provides an overview of the sources explored during the research of a particular topic
Importance of literature review in research:
The importance of literature review in scientific manuscripts can be condensed into an analytical feature to enable the multifold reach of its significance. It adds value to the legitimacy of the research in many ways:
- Provides the interpretation of existing literature in light of updated developments in the field to help in establishing the consistency in knowledge and relevancy of existing materials
- It helps in calculating the impact of the latest information in the field by mapping their progress of knowledge.
- It brings out the dialects of contradictions between various thoughts within the field to establish facts
- The research gaps scrutinized initially are further explored to establish the latest facts of theories to add value to the field
- Indicates the current research place in the schema of a particular field
- Provides information for relevancy and coherency to check the research
- Apart from elucidating the continuance of knowledge, it also points out areas that require further investigation and thus aid as a starting point of any future research
- Justifies the research and sets up the research question
- Sets up a theoretical framework comprising the concepts and theories of the research upon which its success can be judged
- Helps to adopt a more appropriate methodology for the research by examining the strengths and weaknesses of existing research in the same field
- Increases the significance of the results by comparing it with the existing literature
- Provides a point of reference by writing the findings in the scientific manuscript
- Helps to get the due credit from the audience for having done the fact-finding and fact-checking mission in the scientific manuscripts
- The more the reference of relevant sources of it could increase more of its trustworthiness with the readers
- Helps to prevent plagiarism by tailoring and uniquely tweaking the scientific manuscript not to repeat other’s original idea
- By preventing plagiarism , it saves the scientific manuscript from rejection and thus also saves a lot of time and money
- Helps to evaluate, condense and synthesize gist in the author’s own words to sharpen the research focus
- Helps to compare and contrast to show the originality and uniqueness of the research than that of the existing other researches
- Rationalizes the need for conducting the particular research in a specified field
- Helps to collect data accurately for allowing any new methodology of research than the existing ones
- Enables the readers of the manuscript to answer the following questions of its readers for its better chances for publication
- What do the researchers know?
- What do they not know?
- Is the scientific manuscript reliable and trustworthy?
- What are the knowledge gaps of the researcher?
22. It helps the readers to identify the following for further reading of the scientific manuscript:
- What has been already established, discredited and accepted in the particular field of research
- Areas of controversy and conflicts among different schools of thought
- Unsolved problems and issues in the connected field of research
- The emerging trends and approaches
- How the research extends, builds upon and leaves behind from the previous research
A profound literature review with many relevant sources of reference will enhance the chances of the scientific manuscript publication in renowned and reputed scientific journals .

What are Literature Reviews?
So, what is a literature review? "A literature review is an account of what has been published on a topic by accredited scholars and researchers. In writing the literature review, your purpose is to convey to your reader what knowledge and ideas have been established on a topic, and what their strengths and weaknesses are. As a piece of writing, the literature review must be defined by a guiding concept (e.g., your research objective, the problem or issue you are discussing, or your argumentative thesis). It is not just a descriptive list of the material available, or a set of summaries." Taylor, D. The literature review: A few tips on conducting it . University of Toronto Health Sciences Writing Centre.
Goals of Literature Reviews
What are the goals of creating a Literature Review? A literature could be written to accomplish different aims:
- To develop a theory or evaluate an existing theory
- To summarize the historical or existing state of a research topic
- Identify a problem in a field of research
Baumeister, R. F., & Leary, M. R. (1997). Writing narrative literature reviews . Review of General Psychology , 1 (3), 311-320.
What kinds of sources require a Literature Review?
- A research paper assigned in a course
- A thesis or dissertation
- A grant proposal
- An article intended for publication in a journal
All these instances require you to collect what has been written about your research topic so that you can demonstrate how your own research sheds new light on the topic.
Types of Literature Reviews
What kinds of literature reviews are written?
Narrative review: The purpose of this type of review is to describe the current state of the research on a specific topic/research and to offer a critical analysis of the literature reviewed. Studies are grouped by research/theoretical categories, and themes and trends, strengths and weakness, and gaps are identified. The review ends with a conclusion section which summarizes the findings regarding the state of the research of the specific study, the gaps identify and if applicable, explains how the author's research will address gaps identify in the review and expand the knowledge on the topic reviewed.
- Example : Predictors and Outcomes of U.S. Quality Maternity Leave: A Review and Conceptual Framework: 10.1177/08948453211037398
Systematic review : "The authors of a systematic review use a specific procedure to search the research literature, select the studies to include in their review, and critically evaluate the studies they find." (p. 139). Nelson, L. K. (2013). Research in Communication Sciences and Disorders . Plural Publishing.
- Example : The effect of leave policies on increasing fertility: a systematic review: 10.1057/s41599-022-01270-w
Meta-analysis : "Meta-analysis is a method of reviewing research findings in a quantitative fashion by transforming the data from individual studies into what is called an effect size and then pooling and analyzing this information. The basic goal in meta-analysis is to explain why different outcomes have occurred in different studies." (p. 197). Roberts, M. C., & Ilardi, S. S. (2003). Handbook of Research Methods in Clinical Psychology . Blackwell Publishing.
- Example : Employment Instability and Fertility in Europe: A Meta-Analysis: 10.1215/00703370-9164737

A literature review is a review and synthesis of existing research on a topic or research question. A literature review is meant to analyze the scholarly literature, make connections across writings and identify strengths, weaknesses, trends, and missing conversations. A literature review should address different aspects of a topic as it relates to your research question. A literature review goes beyond a description or summary of the literature you have read.

A literature review is not only a summary of key sources, but has an organizational pattern which combines both summary and synthesis, often within specific conceptual categories . A summary is a recap of the important information of the source, but a synthesis is a re-organization, or a reshuffling, of that information in a way that informs how you are planning to investigate a research problem. The analytical features of a literature review might:
- Give a new interpretation of old material or combine new with old interpretations,
- Trace the intellectual progression of the field, including major debates,
- Depending on the situation, evaluate the sources and advise the reader on the most pertinent or relevant research, or
- Usually in the conclusion of a literature review, identify where gaps exist in how a problem has been researched to date.
The purpose of a literature review is to:
- Place each work in the context of its contribution to understanding the research problem being studied.
- Describe the relationship of each work to the others under consideration.
- Identify new ways to interpret prior research.
- Reveal any gaps that exist in the literature.
- Resolve conflicts amongst seemingly contradictory previous studies.
- Identify areas of prior scholarship to prevent duplication of effort.
- Point the way in fulfilling a need for additional research.
- Locate your own research within the context of existing literature [very important].

Literature Review

- Purposes of a Literature Review
- Types of Literature Reviews
- Literature Reviews vs. Systematic Reviews
- Systematic vs. Meta-Analysis
Literature Review is a comprehensive survey of the works published in a particular field of study or line of research, usually over a specific period of time, in the form of an in-depth, critical bibliographic essay or annotated list in which attention is drawn to the most significant works.
Also, we can define a literature review as the collected body of scholarly works related to a topic:
- Summarizes and analyzes previous research relevant to a topic
- Includes scholarly books and articles published in academic journals
- Can be an specific scholarly paper or a section in a research paper
The objective of a Literature Review is to find previous published scholarly works relevant to an specific topic
- Help gather ideas or information
- Keep up to date in current trends and findings
- Help develop new questions
A literature review is important because it:
- Explains the background of research on a topic.
- Demonstrates why a topic is significant to a subject area.
- Helps focus your own research questions or problems
- Discovers relationships between research studies/ideas.
- Suggests unexplored ideas or populations
- Identifies major themes, concepts, and researchers on a topic.
- Tests assumptions; may help counter preconceived ideas and remove unconscious bias.
- Identifies critical gaps, points of disagreement, or potentially flawed methodology or theoretical approaches.
- Indicates potential directions for future research.
All content in this section is from Literature Review Research from Old Dominion University
Keep in mind the following, a literature review is NOT:
Not an essay
Not an annotated bibliography in which you summarize each article that you have reviewed. A literature review goes beyond basic summarizing to focus on the critical analysis of the reviewed works and their relationship to your research question.
Not a research paper where you select resources to support one side of an issue versus another. A lit review should explain and consider all sides of an argument in order to avoid bias, and areas of agreement and disagreement should be highlighted.
A literature review serves several purposes. For example, it
- provides thorough knowledge of previous studies; introduces seminal works.
- helps focus one’s own research topic.
- identifies a conceptual framework for one’s own research questions or problems; indicates potential directions for future research.
- suggests previously unused or underused methodologies, designs, quantitative and qualitative strategies.
- identifies gaps in previous studies; identifies flawed methodologies and/or theoretical approaches; avoids replication of mistakes.
- helps the researcher avoid repetition of earlier research.
- suggests unexplored populations.
- determines whether past studies agree or disagree; identifies controversy in the literature.
- tests assumptions; may help counter preconceived ideas and remove unconscious bias.
As Kennedy (2007) notes*, it is important to think of knowledge in a given field as consisting of three layers. First, there are the primary studies that researchers conduct and publish. Second are the reviews of those studies that summarize and offer new interpretations built from and often extending beyond the original studies. Third, there are the perceptions, conclusions, opinion, and interpretations that are shared informally that become part of the lore of field. In composing a literature review, it is important to note that it is often this third layer of knowledge that is cited as "true" even though it often has only a loose relationship to the primary studies and secondary literature reviews.
Given this, while literature reviews are designed to provide an overview and synthesis of pertinent sources you have explored, there are several approaches to how they can be done, depending upon the type of analysis underpinning your study. Listed below are definitions of types of literature reviews:
Argumentative Review This form examines literature selectively in order to support or refute an argument, deeply imbedded assumption, or philosophical problem already established in the literature. The purpose is to develop a body of literature that establishes a contrarian viewpoint. Given the value-laden nature of some social science research [e.g., educational reform; immigration control], argumentative approaches to analyzing the literature can be a legitimate and important form of discourse. However, note that they can also introduce problems of bias when they are used to to make summary claims of the sort found in systematic reviews.
Integrative Review Considered a form of research that reviews, critiques, and synthesizes representative literature on a topic in an integrated way such that new frameworks and perspectives on the topic are generated. The body of literature includes all studies that address related or identical hypotheses. A well-done integrative review meets the same standards as primary research in regard to clarity, rigor, and replication.
Historical Review Few things rest in isolation from historical precedent. Historical reviews are focused on examining research throughout a period of time, often starting with the first time an issue, concept, theory, phenomena emerged in the literature, then tracing its evolution within the scholarship of a discipline. The purpose is to place research in a historical context to show familiarity with state-of-the-art developments and to identify the likely directions for future research.
Methodological Review A review does not always focus on what someone said [content], but how they said it [method of analysis]. This approach provides a framework of understanding at different levels (i.e. those of theory, substantive fields, research approaches and data collection and analysis techniques), enables researchers to draw on a wide variety of knowledge ranging from the conceptual level to practical documents for use in fieldwork in the areas of ontological and epistemological consideration, quantitative and qualitative integration, sampling, interviewing, data collection and data analysis, and helps highlight many ethical issues which we should be aware of and consider as we go through our study.
Systematic Review This form consists of an overview of existing evidence pertinent to a clearly formulated research question, which uses pre-specified and standardized methods to identify and critically appraise relevant research, and to collect, report, and analyse data from the studies that are included in the review. Typically it focuses on a very specific empirical question, often posed in a cause-and-effect form, such as "To what extent does A contribute to B?"
Theoretical Review The purpose of this form is to concretely examine the corpus of theory that has accumulated in regard to an issue, concept, theory, phenomena. The theoretical literature review help establish what theories already exist, the relationships between them, to what degree the existing theories have been investigated, and to develop new hypotheses to be tested. Often this form is used to help establish a lack of appropriate theories or reveal that current theories are inadequate for explaining new or emerging research problems. The unit of analysis can focus on a theoretical concept or a whole theory or framework.

What's in the name? The difference between a Systematic Review and a Literature Review, and why it matters . By Lynn Kysh from University of Southern California
Systematic review or meta-analysis?
A systematic review answers a defined research question by collecting and summarizing all empirical evidence that fits pre-specified eligibility criteria.
A meta-analysis is the use of statistical methods to summarize the results of these studies.
Systematic reviews, just like other research articles, can be of varying quality. They are a significant piece of work (the Centre for Reviews and Dissemination at York estimates that a team will take 9-24 months), and to be useful to other researchers and practitioners they should have:
- clearly stated objectives with pre-defined eligibility criteria for studies
- explicit, reproducible methodology
- a systematic search that attempts to identify all studies
- assessment of the validity of the findings of the included studies (e.g. risk of bias)
- systematic presentation, and synthesis, of the characteristics and findings of the included studies
Not all systematic reviews contain meta-analysis.
Meta-analysis is the use of statistical methods to summarize the results of independent studies. By combining information from all relevant studies, meta-analysis can provide more precise estimates of the effects of health care than those derived from the individual studies included within a review. More information on meta-analyses can be found in Cochrane Handbook, Chapter 9 .
A meta-analysis goes beyond critique and integration and conducts secondary statistical analysis on the outcomes of similar studies. It is a systematic review that uses quantitative methods to synthesize and summarize the results.
An advantage of a meta-analysis is the ability to be completely objective in evaluating research findings. Not all topics, however, have sufficient research evidence to allow a meta-analysis to be conducted. In that case, an integrative review is an appropriate strategy.

What is a Literature Review?
A literature or narrative review is a comprehensive review and analysis of the published literature on a specific topic or research question. The literature that is reviewed contains: books, articles, academic articles, conference proceedings, association papers, and dissertations. It contains the most pertinent studies and points to important past and current research and practices. It provides background and context, and shows how your research will contribute to the field.
A literature review should:
- Provide a comprehensive and updated review of the literature;
- Explain why this review has taken place;
- Articulate a position or hypothesis;
- Acknowledge and account for conflicting and corroborating points of view
From S age Research Methods
Purpose of a Literature Review
A literature review can be written as an introduction to a study to:
- Demonstrate how a study fills a gap in research
- Compare a study with other research that's been done
Or it can be a separate work (a research article on its own) which:
- Organizes or describes a topic
- Describes variables within a particular issue/problem
Limitations of a Literature Review
Some of the limitations of a literature review are:
- It's a snapshot in time. Unlike other reviews, this one has beginning, a middle and an end. There may be future developments that could make your work less relevant.
- It may be too focused. Some niche studies may miss the bigger picture.
- It can be difficult to be comprehensive. There is no way to make sure all the literature on a topic was considered.
- It is easy to be biased if you stick to top tier journals. There may be other places where people are publishing exemplary research. Look to open access publications and conferences to reflect a more inclusive collection. Also, make sure to include opposing views (and not just supporting evidence).

What is a literature review?
A literature review is an integrated analysis -- not just a summary-- of scholarly writings and other relevant evidence related directly to your research question. That is, it represents a synthesis of the evidence that provides background information on your topic and shows a association between the evidence and your research question.
A literature review may be a stand alone work or the introduction to a larger research paper, depending on the assignment. Rely heavily on the guidelines your instructor has given you.
Why is it important?
A literature review is important because it:
- Explains the background of research on a topic.
- Demonstrates why a topic is significant to a subject area.
- Discovers relationships between research studies/ideas.
- Identifies major themes, concepts, and researchers on a topic.
- Identifies critical gaps and points of disagreement.
- Discusses further research questions that logically come out of the previous studies.

1. Choose a topic. Define your research question.
Your literature review should be guided by your central research question. The literature represents background and research developments related to a specific research question, interpreted and analyzed by you in a synthesized way.
- Make sure your research question is not too broad or too narrow. Is it manageable?
- Begin writing down terms that are related to your question. These will be useful for searches later.
- If you have the opportunity, discuss your topic with your professor and your class mates.
2. Decide on the scope of your review
How many studies do you need to look at? How comprehensive should it be? How many years should it cover?
- This may depend on your assignment. How many sources does the assignment require?
3. Select the databases you will use to conduct your searches.
Make a list of the databases you will search.
Where to find databases:
- use the tabs on this guide
- Find other databases in the Nursing Information Resources web page
- More on the Medical Library web page
- ... and more on the Yale University Library web page
4. Conduct your searches to find the evidence. Keep track of your searches.
- Use the key words in your question, as well as synonyms for those words, as terms in your search. Use the database tutorials for help.
- Save the searches in the databases. This saves time when you want to redo, or modify, the searches. It is also helpful to use as a guide is the searches are not finding any useful results.
- Review the abstracts of research studies carefully. This will save you time.
- Use the bibliographies and references of research studies you find to locate others.
- Check with your professor, or a subject expert in the field, if you are missing any key works in the field.
- Ask your librarian for help at any time.
- Use a citation manager, such as EndNote as the repository for your citations. See the EndNote tutorials for help.
Review the literature
Some questions to help you analyze the research:
- What was the research question of the study you are reviewing? What were the authors trying to discover?
- Was the research funded by a source that could influence the findings?
- What were the research methodologies? Analyze its literature review, the samples and variables used, the results, and the conclusions.
- Does the research seem to be complete? Could it have been conducted more soundly? What further questions does it raise?
- If there are conflicting studies, why do you think that is?
- How are the authors viewed in the field? Has this study been cited? If so, how has it been analyzed?
Tips:
- Review the abstracts carefully.
- Keep careful notes so that you may track your thought processes during the research process.
- Create a matrix of the studies for easy analysis, and synthesis, across all of the studies.

What is a literature review?
![what makes the review of literature important in research](https://rmit.pressbooks.pub/app/uploads/sites/20/2022/11/clay-banks-GX8KBbVmC6c-unsplash-200x300.jpg)
A literature review is a critical analysis of the literature related to your research topic. It evaluates and critiques the literature to establish a theoretical framework for your research topic and/or identify a gap in the existing research that your research will address.
A literature review is not a summary of the literature. You need to engage deeply and critically with the literature. Your literature review should show your understanding of the literature related to your research topic and lead to presenting a rationale for your research.
A literature review focuses on:
- the context of the topic
- key concepts, ideas, theories and methodologies
- key researchers, texts and seminal works
- major issues and debates
- identifying conflicting evidence
- the main questions that have been asked around the topic
- the organisation of knowledge on the topic
- definitions, particularly those that are contested
- showing how your research will advance scholarly knowledge (generally referred to as identifying the ‘gap’).
This module will guide you through the functions of a literature review; the typical process of conducting a literature review (including searching for literature and taking notes); structuring your literature review within your thesis and organising its internal ideas; and styling the language of your literature review.
The purposes of a literature review
A literature review serves two main purposes:
1) To show awareness of the present state of knowledge in a particular field, including:
- seminal authors
- the main empirical research
- theoretical positions
- controversies
- breakthroughs as well as links to other related areas of knowledge.
2) To provide a foundation for the author’s research. To do that, the literature review needs to:
- help the researcher define a hypothesis or a research question, and how answering the question will contribute to the body of knowledge;
- provide a rationale for investigating the problem and the selected methodology;
- provide a particular theoretical lens, support the argument, or identify gaps.

Research on research? If you find this idea rather peculiar, know that nowadays, with the huge amount of information produced daily all around the world, it is becoming more and more difficult to keep up to date with all of it. In addition to the sheer amount of research, there is also its origin. We are witnessing the economic and intellectual emergence of countries like China, Brazil, Turkey, and United Arab Emirates, for example, that are producing scholarly literature in their own languages. So, apart from the effort of gathering information, there must also be translators prepared to unify all of it in a single language to be the object of the literature survey. At Elsevier, our team of translators is ready to support researchers by delivering high-quality scientific translations , in several languages, to serve their research – no matter the topic.
What is a literature review?
A literature review is a study – or, more accurately, a survey – involving scholarly material, with the aim to discuss published information about a specific topic or research question. Therefore, to write a literature review, it is compulsory that you are a real expert in the object of study. The results and findings will be published and made available to the public, namely scientists working in the same area of research.
How to Write a Literature Review
First of all, don’t forget that writing a literature review is a great responsibility. It’s a document that is expected to be highly reliable, especially concerning its sources and findings. You have to feel intellectually comfortable in the area of study and highly proficient in the target language; misconceptions and errors do not have a place in a document as important as a literature review. In fact, you might want to consider text editing services, like those offered at Elsevier, to make sure your literature is following the highest standards of text quality. You want to make sure your literature review is memorable by its novelty and quality rather than language errors.
Writing a literature review requires expertise but also organization. We cannot teach you about your topic of research, but we can provide a few steps to guide you through conducting a literature review:
- Choose your topic or research question: It should not be too comprehensive or too limited. You have to complete your task within a feasible time frame.
- Set the scope: Define boundaries concerning the number of sources, time frame to be covered, geographical area, etc.
- Decide which databases you will use for your searches: In order to search the best viable sources for your literature review, use highly regarded, comprehensive databases to get a big picture of the literature related to your topic.
- Search, search, and search: Now you’ll start to investigate the research on your topic. It’s critical that you keep track of all the sources. Start by looking at research abstracts in detail to see if their respective studies relate to or are useful for your own work. Next, search for bibliographies and references that can help you broaden your list of resources. Choose the most relevant literature and remember to keep notes of their bibliographic references to be used later on.
- Review all the literature, appraising carefully it’s content: After reading the study’s abstract, pay attention to the rest of the content of the articles you deem the “most relevant.” Identify methodologies, the most important questions they address, if they are well-designed and executed, and if they are cited enough, etc.
If it’s the first time you’ve published a literature review, note that it is important to follow a special structure. Just like in a thesis, for example, it is expected that you have an introduction – giving the general idea of the central topic and organizational pattern – a body – which contains the actual discussion of the sources – and finally the conclusion or recommendations – where you bring forward whatever you have drawn from the reviewed literature. The conclusion may even suggest there are no agreeable findings and that the discussion should be continued.
Why are literature reviews important?
Literature reviews constantly feed new research, that constantly feeds literature reviews…and we could go on and on. The fact is, one acts like a force over the other and this is what makes science, as a global discipline, constantly develop and evolve. As a scientist, writing a literature review can be very beneficial to your career, and set you apart from the expert elite in your field of interest. But it also can be an overwhelming task, so don’t hesitate in contacting Elsevier for text editing services, either for profound edition or just a last revision. We guarantee the very highest standards. You can also save time by letting us suggest and make the necessary amendments to your manuscript, so that it fits the structural pattern of a literature review. Who knows how many worldwide researchers you will impact with your next perfectly written literature review.

Frequently asked questions
What is the purpose of a literature review.
There are several reasons to conduct a literature review at the beginning of a research project:
- To familiarize yourself with the current state of knowledge on your topic
- To ensure that you’re not just repeating what others have already done
- To identify gaps in knowledge and unresolved problems that your research can address
- To develop your theoretical framework and methodology
- To provide an overview of the key findings and debates on the topic
Writing the literature review shows your reader how your work relates to existing research and what new insights it will contribute.
Frequently asked questions: Academic writing
A rhetorical tautology is the repetition of an idea of concept using different words.
Rhetorical tautologies occur when additional words are used to convey a meaning that has already been expressed or implied. For example, the phrase “armed gunman” is a tautology because a “gunman” is by definition “armed.”
A logical tautology is a statement that is always true because it includes all logical possibilities.
Logical tautologies often take the form of “either/or” statements (e.g., “It will rain, or it will not rain”) or employ circular reasoning (e.g., “she is untrustworthy because she can’t be trusted”).
You may have seen both “appendices” or “appendixes” as pluralizations of “ appendix .” Either spelling can be used, but “appendices” is more common (including in APA Style ). Consistency is key here: make sure you use the same spelling throughout your paper.
The purpose of a lab report is to demonstrate your understanding of the scientific method with a hands-on lab experiment. Course instructors will often provide you with an experimental design and procedure. Your task is to write up how you actually performed the experiment and evaluate the outcome.
In contrast, a research paper requires you to independently develop an original argument. It involves more in-depth research and interpretation of sources and data.
A lab report is usually shorter than a research paper.
The sections of a lab report can vary between scientific fields and course requirements, but it usually contains the following:
- Title: expresses the topic of your study
- Abstract: summarizes your research aims, methods, results, and conclusions
- Introduction: establishes the context needed to understand the topic
- Method: describes the materials and procedures used in the experiment
- Results: reports all descriptive and inferential statistical analyses
- Discussion: interprets and evaluates results and identifies limitations
- Conclusion: sums up the main findings of your experiment
- References: list of all sources cited using a specific style (e.g. APA)
- Appendices: contains lengthy materials, procedures, tables or figures
A lab report conveys the aim, methods, results, and conclusions of a scientific experiment . Lab reports are commonly assigned in science, technology, engineering, and mathematics (STEM) fields.
The abstract is the very last thing you write. You should only write it after your research is complete, so that you can accurately summarize the entirety of your thesis , dissertation or research paper .
If you’ve gone over the word limit set for your assignment, shorten your sentences and cut repetition and redundancy during the editing process. If you use a lot of long quotes , consider shortening them to just the essentials.
If you need to remove a lot of words, you may have to cut certain passages. Remember that everything in the text should be there to support your argument; look for any information that’s not essential to your point and remove it.
To make this process easier and faster, you can use a paraphrasing tool . With this tool, you can rewrite your text to make it simpler and shorter. If that’s not enough, you can copy-paste your paraphrased text into the summarizer . This tool will distill your text to its core message.
Revising, proofreading, and editing are different stages of the writing process .
- Revising is making structural and logical changes to your text—reformulating arguments and reordering information.
- Editing refers to making more local changes to things like sentence structure and phrasing to make sure your meaning is conveyed clearly and concisely.
- Proofreading involves looking at the text closely, line by line, to spot any typos and issues with consistency and correct them.
The literature review usually comes near the beginning of your thesis or dissertation . After the introduction , it grounds your research in a scholarly field and leads directly to your theoretical framework or methodology .
A literature review is a survey of scholarly sources (such as books, journal articles, and theses) related to a specific topic or research question .
It is often written as part of a thesis, dissertation , or research paper , in order to situate your work in relation to existing knowledge.
Avoid citing sources in your abstract . There are two reasons for this:
- The abstract should focus on your original research, not on the work of others.
- The abstract should be self-contained and fully understandable without reference to other sources.
There are some circumstances where you might need to mention other sources in an abstract: for example, if your research responds directly to another study or focuses on the work of a single theorist. In general, though, don’t include citations unless absolutely necessary.
An abstract is a concise summary of an academic text (such as a journal article or dissertation ). It serves two main purposes:
- To help potential readers determine the relevance of your paper for their own research.
- To communicate your key findings to those who don’t have time to read the whole paper.
Abstracts are often indexed along with keywords on academic databases, so they make your work more easily findable. Since the abstract is the first thing any reader sees, it’s important that it clearly and accurately summarizes the contents of your paper.
In a scientific paper, the methodology always comes after the introduction and before the results , discussion and conclusion . The same basic structure also applies to a thesis, dissertation , or research proposal .
Depending on the length and type of document, you might also include a literature review or theoretical framework before the methodology.
Whether you’re publishing a blog, submitting a research paper , or even just writing an important email, there are a few techniques you can use to make sure it’s error-free:
- Take a break : Set your work aside for at least a few hours so that you can look at it with fresh eyes.
- Proofread a printout : Staring at a screen for too long can cause fatigue – sit down with a pen and paper to check the final version.
- Use digital shortcuts : Take note of any recurring mistakes (for example, misspelling a particular word, switching between US and UK English , or inconsistently capitalizing a term), and use Find and Replace to fix it throughout the document.
If you want to be confident that an important text is error-free, it might be worth choosing a professional proofreading service instead.
Editing and proofreading are different steps in the process of revising a text.
Editing comes first, and can involve major changes to content, structure and language. The first stages of editing are often done by authors themselves, while a professional editor makes the final improvements to grammar and style (for example, by improving sentence structure and word choice ).
Proofreading is the final stage of checking a text before it is published or shared. It focuses on correcting minor errors and inconsistencies (for example, in punctuation and capitalization ). Proofreaders often also check for formatting issues, especially in print publishing.
The cost of proofreading depends on the type and length of text, the turnaround time, and the level of services required. Most proofreading companies charge per word or page, while freelancers sometimes charge an hourly rate.
For proofreading alone, which involves only basic corrections of typos and formatting mistakes, you might pay as little as $0.01 per word, but in many cases, your text will also require some level of editing , which costs slightly more.
It’s often possible to purchase combined proofreading and editing services and calculate the price in advance based on your requirements.
There are many different routes to becoming a professional proofreader or editor. The necessary qualifications depend on the field – to be an academic or scientific proofreader, for example, you will need at least a university degree in a relevant subject.
For most proofreading jobs, experience and demonstrated skills are more important than specific qualifications. Often your skills will be tested as part of the application process.
To learn practical proofreading skills, you can choose to take a course with a professional organization such as the Society for Editors and Proofreaders . Alternatively, you can apply to companies that offer specialized on-the-job training programmes, such as the Scribbr Academy .

A literature review is a comprehensive summary of previous research on a topic. The literature review surveys scholarly articles, books, and other sources relevant to a particular area of research. The review should enumerate, describe, summarize, objectively evaluate and clarify this previous research. It should give a theoretical base for the research and help you (the author) determine the nature of your research. The literature review acknowledges the work of previous researchers, and in so doing, assures the reader that your work has been well conceived. It is assumed that by mentioning a previous work in the field of study, that the author has read, evaluated, and assimiliated that work into the work at hand.
A literature review creates a "landscape" for the reader, giving her or him a full understanding of the developments in the field. This landscape informs the reader that the author has indeed assimilated all (or the vast majority of) previous, significant works in the field into her or his research.
"In writing the literature review, the purpose is to convey to the reader what knowledge and ideas have been established on a topic, and what their strengths and weaknesses are. The literature review must be defined by a guiding concept (eg. your research objective, the problem or issue you are discussing, or your argumentative thesis). It is not just a descriptive list of the material available, or a set of summaries.( http://www.writing.utoronto.ca/advice/specific-types-of-writing/literature-review )

How to Write a Literature Review? A Beginner’s Guide
Sooner or later in your academic path, you will be required to compose a literature review. So, it’s important to approach this task well-prepared and understand how to write a literature review inside out.
Are you interested in how to write lit review projects correctly and cover the subject comprehensively, from all angles? This article will explore the concept of review of literature , dwell on how to write a literature review in line with your professor’s expectations, and share a universal literature review template for your usage.
What Is the Purpose of a Literature Review?
To understand what should be included in a literature review , you need to understand its purpose and value in a larger work. A well-researched and written lit review usually addresses the following objectives:
- Inform . The fundamental purpose of any review of literature is to provide the foundation of knowledge on a specific topic or phenomenon. You explore what people have learned about it from prior studies and summarize those findings to inform your readers.
- Give credit . Another purpose of a lit review is to identify researchers who have contributed to the advancement of research on your chosen literature review topic and have produced the most valuable findings. This way, you pay tribute to those researchers and showcase your knowledge of the most considerable influencers.
- Identify gaps . By performing a thorough review of literature , you may not only discover what is known about your topic but also find out what it yet to be learned about it. As a result of reviewing the available evidence, you may identify gaps for addressing through your academic inquiry.
- Identify patterns . Those who know how to write a literature review can also effectively embrace data trends and patterns in the collected dataset. As a result, they can present a more nuanced analysis of the existing knowledge in your literature review and uncover dependencies that inform people’s understanding of certain phenomena and processes.
- Contextualize research . When you perform lit review writing, you can also create a spot for your own study within the broad field of your academic research interest. This way, you show to your readers that you can effectively navigate the landscape of your academic area.
These purposes lay the foundation for understanding how to write a literature review that will attain all academic goals. You simply need to use this list as your checklist for structuring an impactful lit review and including all vital data in it.
How to Write a Literature Review?
Now, we come to the main topic of this article – how to write a good literature review for dissertation projects, research papers, and other works. Follow the steps we’ve covered below to arrive at a consistent, logical piece of lit review .
Identify Relevant Sources
Any literature review writing starts with academic research. You should look for sources that explore your topic from various angles and provide valuable literature review findings to expand your knowledge on the subject. It’s best to look for subject-specific books first and then go through academic databases that publish journal articles. This way, you will start with the evidence of the highest reliability level and move on to expand your literature review dataset conveniently.
Screen Sources for Quality
The best solution on how to write a literature review without challenges is to rely on high-quality evidence. Your task is to research extensively in reliable academic databases to find peer-reviewed academic journals and books written by experts in your field. Don’t over-rely on online sources in your literature review, like blogs or opinion pieces, because they rarely possess the needed degree of credibility for an academic review. By choosing only industry-approved sources from qualified professionals, you can build a solid foundation for your writing and impress the audience.
Determine Data Patterns and Gaps
How to write a literature review of value for your readers? One of the best approaches is to go beyond mere summarization of what other researchers have found on the subject and to apply critical thinking and data categorization. This way, you will manage to uncover existing patterns and trends and examine those dependencies in your literature review. A systematic, critical approach is always evaluated much higher than a simple outline of what people say on your subject.
![](http://academicpaper.online/777/templates/cheerup/res/banner1.gif)
Draft an Outline
Now, it’s time to compose an outline for a literature review . The outline should include the main concepts you’re planning to cover in the literature review text and should structure the narrative consistently. By means of composing an outline before the actual writing process, you give yourself a hands-on roadmap for composing a logically flowing piece. As a result of using an outline, you will write the literature review faster and will avoid the risk of going off-topic.
Compose the Review
With a good and detailed outline, you should have no more problems or concerns about how to write a literature review . The writing process should go quickly and smoothly when you have all your evidence at your fingertips, categorized by themes and requiring only proper summarization in the text.
We recommend starting with a broad introduction to the topic and concepts related to it. You should give definitions and explain the topic’s features and components that require attention in the research process. After that, you may briefly outline the main sections of your review and then proceed to the exploration of each section in depth.
At times, your professor will give you a specific structure for review writing – such as the general introduction, coverage of theories, and then coverage of empirical evidence. At times, it may be a review of the data search strategy and a report on the identified resources that follow. In any case, you should follow the tutor’s prompt closely to ensure compliance with the task.

More Pro Tips for Writing a Literature Review
If you’re still unsure about how to do a literature review with excellence, these pro tips may improve your understanding of this task type.
- Mind the audience . Understanding how to do a literature review for a research paper often has little to do with how to write literature review for thesis . This difference is explained by the fact that these types of academic work are of different lengths and pursue different scholarly goals. This way, you may need to cover only some basic seminal research in the review of literature for a research paper but will need to dig deeper into theoretical and applied research with deeper analysis and more critical thinking when dealing with a thesis.
- Mind the length . How long should a literature review be ? This is a vital question that you should answer before starting the outlining and writing process. Ask your professor if you’re not sure or apply the rule of thumb, where this section usually takes from 15% to 25% of the entire paper.
- Mind the structure . It’s important to cover all lit review aspects that your professor wants to see in the paper; otherwise, you risk getting a low grade even if your literature review is comprehensive and interesting. What should a literature review include ? In most cases, you will be required to cover some seminal research works in your literature review to show that you understand who the pioneers in the field are, and what contribution they have made to the topic’s exploration. Next, you should examine relevant theories that inform studies in your subject. At the end of the literature review, you should typically cite a variety of studies of applied nature, thus showing what empirical research is conducted in your academic field.

Ten Simple Rules for Writing a Literature Review
Marco pautasso.
1 Centre for Functional and Evolutionary Ecology (CEFE), CNRS, Montpellier, France
2 Centre for Biodiversity Synthesis and Analysis (CESAB), FRB, Aix-en-Provence, France
Literature reviews are in great demand in most scientific fields. Their need stems from the ever-increasing output of scientific publications [1] . For example, compared to 1991, in 2008 three, eight, and forty times more papers were indexed in Web of Science on malaria, obesity, and biodiversity, respectively [2] . Given such mountains of papers, scientists cannot be expected to examine in detail every single new paper relevant to their interests [3] . Thus, it is both advantageous and necessary to rely on regular summaries of the recent literature. Although recognition for scientists mainly comes from primary research, timely literature reviews can lead to new synthetic insights and are often widely read [4] . For such summaries to be useful, however, they need to be compiled in a professional way [5] .
When starting from scratch, reviewing the literature can require a titanic amount of work. That is why researchers who have spent their career working on a certain research issue are in a perfect position to review that literature. Some graduate schools are now offering courses in reviewing the literature, given that most research students start their project by producing an overview of what has already been done on their research issue [6] . However, it is likely that most scientists have not thought in detail about how to approach and carry out a literature review.
Reviewing the literature requires the ability to juggle multiple tasks, from finding and evaluating relevant material to synthesising information from various sources, from critical thinking to paraphrasing, evaluating, and citation skills [7] . In this contribution, I share ten simple rules I learned working on about 25 literature reviews as a PhD and postdoctoral student. Ideas and insights also come from discussions with coauthors and colleagues, as well as feedback from reviewers and editors.
Rule 1: Define a Topic and Audience
How to choose which topic to review? There are so many issues in contemporary science that you could spend a lifetime of attending conferences and reading the literature just pondering what to review. On the one hand, if you take several years to choose, several other people may have had the same idea in the meantime. On the other hand, only a well-considered topic is likely to lead to a brilliant literature review [8] . The topic must at least be:
- interesting to you (ideally, you should have come across a series of recent papers related to your line of work that call for a critical summary),
- an important aspect of the field (so that many readers will be interested in the review and there will be enough material to write it), and
- a well-defined issue (otherwise you could potentially include thousands of publications, which would make the review unhelpful).
Ideas for potential reviews may come from papers providing lists of key research questions to be answered [9] , but also from serendipitous moments during desultory reading and discussions. In addition to choosing your topic, you should also select a target audience. In many cases, the topic (e.g., web services in computational biology) will automatically define an audience (e.g., computational biologists), but that same topic may also be of interest to neighbouring fields (e.g., computer science, biology, etc.).
Rule 2: Search and Re-search the Literature
After having chosen your topic and audience, start by checking the literature and downloading relevant papers. Five pieces of advice here:
- keep track of the search items you use (so that your search can be replicated [10] ),
- keep a list of papers whose pdfs you cannot access immediately (so as to retrieve them later with alternative strategies),
- use a paper management system (e.g., Mendeley, Papers, Qiqqa, Sente),
- define early in the process some criteria for exclusion of irrelevant papers (these criteria can then be described in the review to help define its scope), and
- do not just look for research papers in the area you wish to review, but also seek previous reviews.
The chances are high that someone will already have published a literature review ( Figure 1 ), if not exactly on the issue you are planning to tackle, at least on a related topic. If there are already a few or several reviews of the literature on your issue, my advice is not to give up, but to carry on with your own literature review,
![Click on image to zoom An external file that holds a picture, illustration, etc.

The bottom-right situation (many literature reviews but few research papers) is not just a theoretical situation; it applies, for example, to the study of the impacts of climate change on plant diseases, where there appear to be more literature reviews than research studies [33] .
- discussing in your review the approaches, limitations, and conclusions of past reviews,
- trying to find a new angle that has not been covered adequately in the previous reviews, and
- incorporating new material that has inevitably accumulated since their appearance.
When searching the literature for pertinent papers and reviews, the usual rules apply:
- be thorough,
- use different keywords and database sources (e.g., DBLP, Google Scholar, ISI Proceedings, JSTOR Search, Medline, Scopus, Web of Science), and
- look at who has cited past relevant papers and book chapters.
Rule 3: Take Notes While Reading
If you read the papers first, and only afterwards start writing the review, you will need a very good memory to remember who wrote what, and what your impressions and associations were while reading each single paper. My advice is, while reading, to start writing down interesting pieces of information, insights about how to organize the review, and thoughts on what to write. This way, by the time you have read the literature you selected, you will already have a rough draft of the review.
Of course, this draft will still need much rewriting, restructuring, and rethinking to obtain a text with a coherent argument [11] , but you will have avoided the danger posed by staring at a blank document. Be careful when taking notes to use quotation marks if you are provisionally copying verbatim from the literature. It is advisable then to reformulate such quotes with your own words in the final draft. It is important to be careful in noting the references already at this stage, so as to avoid misattributions. Using referencing software from the very beginning of your endeavour will save you time.
Rule 4: Choose the Type of Review You Wish to Write
After having taken notes while reading the literature, you will have a rough idea of the amount of material available for the review. This is probably a good time to decide whether to go for a mini- or a full review. Some journals are now favouring the publication of rather short reviews focusing on the last few years, with a limit on the number of words and citations. A mini-review is not necessarily a minor review: it may well attract more attention from busy readers, although it will inevitably simplify some issues and leave out some relevant material due to space limitations. A full review will have the advantage of more freedom to cover in detail the complexities of a particular scientific development, but may then be left in the pile of the very important papers “to be read” by readers with little time to spare for major monographs.
There is probably a continuum between mini- and full reviews. The same point applies to the dichotomy of descriptive vs. integrative reviews. While descriptive reviews focus on the methodology, findings, and interpretation of each reviewed study, integrative reviews attempt to find common ideas and concepts from the reviewed material [12] . A similar distinction exists between narrative and systematic reviews: while narrative reviews are qualitative, systematic reviews attempt to test a hypothesis based on the published evidence, which is gathered using a predefined protocol to reduce bias [13] , [14] . When systematic reviews analyse quantitative results in a quantitative way, they become meta-analyses. The choice between different review types will have to be made on a case-by-case basis, depending not just on the nature of the material found and the preferences of the target journal(s), but also on the time available to write the review and the number of coauthors [15] .
Rule 5: Keep the Review Focused, but Make It of Broad Interest
Whether your plan is to write a mini- or a full review, it is good advice to keep it focused 16 , 17 . Including material just for the sake of it can easily lead to reviews that are trying to do too many things at once. The need to keep a review focused can be problematic for interdisciplinary reviews, where the aim is to bridge the gap between fields [18] . If you are writing a review on, for example, how epidemiological approaches are used in modelling the spread of ideas, you may be inclined to include material from both parent fields, epidemiology and the study of cultural diffusion. This may be necessary to some extent, but in this case a focused review would only deal in detail with those studies at the interface between epidemiology and the spread of ideas.
While focus is an important feature of a successful review, this requirement has to be balanced with the need to make the review relevant to a broad audience. This square may be circled by discussing the wider implications of the reviewed topic for other disciplines.
Rule 6: Be Critical and Consistent
Reviewing the literature is not stamp collecting. A good review does not just summarize the literature, but discusses it critically, identifies methodological problems, and points out research gaps [19] . After having read a review of the literature, a reader should have a rough idea of:
- the major achievements in the reviewed field,
- the main areas of debate, and
- the outstanding research questions.
It is challenging to achieve a successful review on all these fronts. A solution can be to involve a set of complementary coauthors: some people are excellent at mapping what has been achieved, some others are very good at identifying dark clouds on the horizon, and some have instead a knack at predicting where solutions are going to come from. If your journal club has exactly this sort of team, then you should definitely write a review of the literature! In addition to critical thinking, a literature review needs consistency, for example in the choice of passive vs. active voice and present vs. past tense.
Rule 7: Find a Logical Structure
Like a well-baked cake, a good review has a number of telling features: it is worth the reader's time, timely, systematic, well written, focused, and critical. It also needs a good structure. With reviews, the usual subdivision of research papers into introduction, methods, results, and discussion does not work or is rarely used. However, a general introduction of the context and, toward the end, a recapitulation of the main points covered and take-home messages make sense also in the case of reviews. For systematic reviews, there is a trend towards including information about how the literature was searched (database, keywords, time limits) [20] .
How can you organize the flow of the main body of the review so that the reader will be drawn into and guided through it? It is generally helpful to draw a conceptual scheme of the review, e.g., with mind-mapping techniques. Such diagrams can help recognize a logical way to order and link the various sections of a review [21] . This is the case not just at the writing stage, but also for readers if the diagram is included in the review as a figure. A careful selection of diagrams and figures relevant to the reviewed topic can be very helpful to structure the text too [22] .
Rule 8: Make Use of Feedback
Reviews of the literature are normally peer-reviewed in the same way as research papers, and rightly so [23] . As a rule, incorporating feedback from reviewers greatly helps improve a review draft. Having read the review with a fresh mind, reviewers may spot inaccuracies, inconsistencies, and ambiguities that had not been noticed by the writers due to rereading the typescript too many times. It is however advisable to reread the draft one more time before submission, as a last-minute correction of typos, leaps, and muddled sentences may enable the reviewers to focus on providing advice on the content rather than the form.
Feedback is vital to writing a good review, and should be sought from a variety of colleagues, so as to obtain a diversity of views on the draft. This may lead in some cases to conflicting views on the merits of the paper, and on how to improve it, but such a situation is better than the absence of feedback. A diversity of feedback perspectives on a literature review can help identify where the consensus view stands in the landscape of the current scientific understanding of an issue [24] .
Rule 9: Include Your Own Relevant Research, but Be Objective
In many cases, reviewers of the literature will have published studies relevant to the review they are writing. This could create a conflict of interest: how can reviewers report objectively on their own work [25] ? Some scientists may be overly enthusiastic about what they have published, and thus risk giving too much importance to their own findings in the review. However, bias could also occur in the other direction: some scientists may be unduly dismissive of their own achievements, so that they will tend to downplay their contribution (if any) to a field when reviewing it.
In general, a review of the literature should neither be a public relations brochure nor an exercise in competitive self-denial. If a reviewer is up to the job of producing a well-organized and methodical review, which flows well and provides a service to the readership, then it should be possible to be objective in reviewing one's own relevant findings. In reviews written by multiple authors, this may be achieved by assigning the review of the results of a coauthor to different coauthors.
Rule 10: Be Up-to-Date, but Do Not Forget Older Studies
Given the progressive acceleration in the publication of scientific papers, today's reviews of the literature need awareness not just of the overall direction and achievements of a field of inquiry, but also of the latest studies, so as not to become out-of-date before they have been published. Ideally, a literature review should not identify as a major research gap an issue that has just been addressed in a series of papers in press (the same applies, of course, to older, overlooked studies (“sleeping beauties” [26] )). This implies that literature reviewers would do well to keep an eye on electronic lists of papers in press, given that it can take months before these appear in scientific databases. Some reviews declare that they have scanned the literature up to a certain point in time, but given that peer review can be a rather lengthy process, a full search for newly appeared literature at the revision stage may be worthwhile. Assessing the contribution of papers that have just appeared is particularly challenging, because there is little perspective with which to gauge their significance and impact on further research and society.
Inevitably, new papers on the reviewed topic (including independently written literature reviews) will appear from all quarters after the review has been published, so that there may soon be the need for an updated review. But this is the nature of science [27] – [32] . I wish everybody good luck with writing a review of the literature.

1. Introduction
- RQ1 (scientific): How have researchers studied the impact of COVID-19 on logistics and supply chain processes? Which industrial sectors were mostly studied and why? Which additional topics can be related to COVID-19 and logistics/supply chain?
- RQ2 (practical): What effects of COVID-19 on logistics and supply chain processes were experienced by companies?
2. Materials and Methods
2.1. systematic literature review, 2.1.1. sample creation, 2.1.2. descriptive analyses, 2.1.3. paper classification.
- Macro theme: sustainability, resilience, risk, information technology, economics, performance, planning and food security. This classification represents paper’s core topic.
- Industrial sector: aerospace, agri-food, apparel, automotive, construction, e-commerce, electronic, energy, fast-moving consumer goods, food, healthcare, logistics, manufacturing and service.
- Data collection method: questionnaire/interview, third-party sources or case study. This classification represents the method used by the authors to collect the data useful to their study.
- Research method: statistical, decision-making, simulation, empirical, literature review or economic. This category describes the tool used by the authors to conduct the study and reach the related goals.
- Specific method, e.g., descriptive statistics, structural equation modeling (SEM), multi-criteria decision making (MCDM), etc.; this feature describes more accurately the type of work carried out by the authors and the tools used.
- Country: it reflects the geographical area in which the study was carried out, in terms, for instance, of the country in which a sample of people has been interviewed or where empirical data were collected, or where the simulation was set. This method of classification, although more elaborated, was preferred over traditional approaches, in which the country of the study is defined based merely on the affiliation of the first author of the paper, because the exact knowledge of the country in which the study was carried out is, for sure, a more representative source of information about the research. This is true in general, but it is even more important for this subject matter, as the management of the COVID-19 pandemic was made on a country or regional basis, with significant differences from country to country; knowing the exact location of the study helps in better interpreting the research outcomes. Possible entries in this field also include “multiple countries” and “not specified”, with the obvious meanings of the terms.
2.1.4. Cross-Analyses
2.1.5. interrelated aspects, 2.2. case study, 2.2.1. data collection.
- Economic data: some key economic data were retrieved from the company’s balance sheet, from 2019 up to the latest available document, which refers to 2022.
- Organizational data: these data describe changes in the operational, decision-making and business structure of the company in terms, e.g., of number of employees hired, number of drivers, etc.
- The related data were collected and elaborated between July and September 2023.
2.2.2. Survey Phase
2.2.3. analysis and summary, 3. results—systematic literature review, 3.1. descriptive statistics, 3.2. common classification fields, 3.2.1. macro theme, 3.2.2. industrial sector, 3.2.3. data collection method, 3.2.4. research method, 3.2.5. country, 3.3. cross-analyses, 3.3.1. macro theme vs. industrial sector, 3.3.2. research method vs. macro theme, 3.4. interrelated aspects, 4. results—case study, 4.1. company overview, 4.2. pre-covid-19 period, 4.3. covid-19 period, 4.4. post-covid-19 period, 4.5. analysis and summary.
- Strengths : at present, Company A benefits from a robust network of relationships with customers and suppliers (e.g., drivers), which was leveraged during the pandemic period to provide a rapid response to the increased request by the consumers. The company has also leveraged the usage of digital technologies, which made logistics activities more efficient and, again, allowed the company to respond to consumer demand in the pandemic period.
- Weaknesses : Company A has suffered from low economic results, in particular in the post-COVID-19 period, mainly due to the high production costs. Efforts must be made by the company to reduce expenses. At the same time, however, the service level, in terms of delivery lead time or on-time delivery, should be safeguarded.
- Opportunities : the growth of e-commerce, experienced in the COVID-19 period but expected to last over time, creates opportunities for increasing the volume of items handled by Company A. Indeed, the survey phase demonstrated that the company’s consumers have shifted towards the usage of online sales; hence, the company could consider investing in this area to increase its market share. By leveraging the e-commerce logistics and diversifying service, expansions could also be possible at an international level. Even if the company has already embraced the implementation of digital technologies, some emerging technologies (e.g., drones or advanced traceability systems) could also be introduced for further improving the logistics efficiency. Finally, sustainability is another opportunity to be leveraged, because of the current push towards the adoption of environmental-friendly logistics solutions. Examples of those solutions include a reduction in CO 2 emissions, and the usage of electric vehicles or zero-impact materials.
- Threats : the growth of e-commerce can be seen as an opportunity, but because many logistics companies have already entered this field, the sector is characterized by very high competition, which could limit the market share of Company A; this could instead be seen as a threat needing to be properly managed. Another threat comes from the increased cost of fuel, which, for sure, for a logistics company plays an important role in determining the cost of the transport activities (also, having previously observed that the company suffered from a limited revenue in recent years). This factor could further push towards the adoption of environmentally friendly transport modes (e.g., electric vehicles), which have been previously mentioned as an opportunity for leveraging in the logistics sector.

The Original Article was published on 16 March 2024
The systematic review and meta-analysis of newborn animal models by Irene Lok et al. is the first to extensively summarize the literature regarding postnatal systemic corticosteroid use on lung development of newborn rodent models. The meta-analysis showed that the use of postnatal corticosteroids resulted in a reduction in body weight along with persistent alveolar simplification. The most frequently used corticosteroid was dexamethasone. Corticosteroids have been extensively used in clinical trials in preterm newborns. Trials using early systemic administration of corticosteroids reduced the rate of BPD or mortality with no increase in the rates of cerebral palsy. Use of late systemic corticosteroids (administered >7 days after birth) also reduced the rate of BPD, mortality, and combined outcome of mortality or BPD. Late systemic corticosteroids showed no impact on the rates of neurodevelopmental outcomes in later childhood. It is important to note that later stages of inflammation leading to a more severe form of BPD continues to be a problem with no clear therapy in sight. The authors made a critical point in their paper – the negative effects of steroids were greater in the normal lung control animals than in the injured. This conveys caution in using steroids in a prophylactic manner.
Use of systemic corticosteroids in clinical trials have shown good response in preterm neonates evidenced by reduced rate of bronchopulmonary dysplasia.
Rodent models have not shown a similar beneficial response.
Use of systemic corticosteroids have caused greater arrest of lung development in rodent models with normal lungs compared to those with lung damage.
Corticosteroids are widely prescribed in the clinical practice of neonatology. While the use of corticosteroids to reduce the severity of neonatal preterm lung disease had declined following the American Academy of Pediatrics guidelines in 2002, postnatal steroid use seems to be regaining popularity in clinical practice. 1 , 2 Animal models have been integral to our current understanding of neonatal physiology and the development of therapies in preclinical settings.
Up to 50% of infants born less than 28 weeks of gestational age develop bronchopulmonary dysplasia (BPD), a chronic lung disease of premature infants. 3 Inflammation is considered a major cause of BPD. 4 Over 50 years have passed since the first randomized controlled trial (RCT) of postnatal systemic corticosteroids to treat respiratory problems in preterm infants. 5 However, the first randomized controlled trial of corticosteroids to specifically treat BPD was reported in the 1980s. 6 The literature includes about 90 RCTs of corticosteroids to prevent or treat BPD, enrolling more than 9000 infants. 7
This systematic review and meta-analysis of newborn animal models by Irene Lok et al. is the first to extensively summarize the current preclinical literature regarding postnatal systemic corticosteroids on lung development in healthy and diseased newborn rodent models. 8 The meta-analysis showed that the use of postnatal corticosteroids resulted in a reduction in body weight along with persistent alveolar simplification. The most frequently used corticosteroid was dexamethasone (98%). In 73% of the rodent studies, corticosteroids were started in the first four postnatal days. A significant decrease in body weight was noted in the newborn rodents who were started on steroids before 15 days of age. This review included studies in both healthy newborn animals and those with hyperoxia-induced lung injury.
The current focus on the developmental evolution of BPD is the appearance of alveolar simplification, resulting in fewer but larger alveoli, producing less surface area for gas exchange. The authors demonstrate that corticosteroid treatment resulted in a reduction in the post-treatment number of alveoli as shown by reduced radial alveolar count (RAC) (Fig. 1 ), an increase in chord length (Lm), and a reduction in alveolar surface area in all steroid-treated newborn animals compared to non-steroid-treated controls. These measurements have been performed on a great many studies of steroid effects on the developing lung. Two possible explanations are offered by the authors for the absence of improvement following steroid treatment in RAC and Lm: (1) steroid-induced arrest of alveolar growth due to premature induction of maturation of lung cells; and (2) inability of steroid to dampen the impact of injury and inflammation caused by hyperoxia. 8
![what makes the review of literature important in research figure 1](https://media.springernature.com/lw685/springer-static/image/art%3A10.1038%2Fs41390-024-03361-7/MediaObjects/41390_2024_3361_Fig1_HTML.png)
Chord Length – a test line is placed (dashed orange line with arrows) and the distance between alveolar structures that cross the line is measured, intercepts can span one alveolus (A), or cross the alveolar duct (D). Vessels are not counted. Mean Linear Intercept – 100 µm grid placed over lung fields (representative black lines), lung structures in the vertical and horizontal that intercept grid are counted (examples marked with asterisks), and the average linear distance between structures is calculated for the entire grid. Radial Alveolar Counts – a perpendicular line is drawn from a terminal bronchiole ending as a respiratory bronchiole to the lung interlobar septa (blue line) and the number of bisected saccules is counted (black numbers). Alveolar Counts – Alveoli structures are counted in sequential sections (not shown) within a given high-powered field with alveoli included (black X) if touching the inclusion line (green line) or excluded if touching the exclusion line (red line). For alveoli opening into alveolar ducts, a counting event is the presence of a bridge connecting the free edges of alveolar septae in the sampling section but not the sequential look-up section.
Studies administering postnatal corticosteroids to large (preterm) animals did not meet the inclusion criteria of this systematic review either because follow-up times were under 24 h or corticosteroids were not systemically administered. As introduced by the authors, it is possible that large animal models could better represent the multifactorial nature of BPD and could serve as better models to study the detrimental and beneficial effects of corticosteroids on lung development and BPD. It is clear that rodent animal models have not been successful in demonstrating the positive impact of steroid therapy that has been demonstrated in human clinical trials. This failure is partially attributed to the rapid lung development in rodents. For instance, a 10-day steroid treatment given to mice covers most of the saccular and almost half of the alveolar stage of lung development. This represents, physiologically, a long duration of treatment in preterm humans which clinically is never done. Administration of corticosteroid use in the first 10 days of postnatal life in a mouse would be equivalent to giving the drug from 24 weeks to almost a year of postnatal life in the human neonate/infant. 9 Newborn rodents at birth are anatomically in the same late canalicular/ early saccular stage of lung development as a 24-week gestation preterm infant, but the rodent newborns are born at term and are not surfactant deficient but do resemble the state of a preterm infant who has received antenatal steroids to enhance surfactant production. Unfortunately, these differences preclude direct translation of pathology and timing of the postnatal steroid intervention in extremely preterm newborns to rodent models of BPD. Though rodents share similarities it is important to note that rats and mice are not interchangeable as animal models. 9 The mice have smaller alveoli and have less lung parenchyma as a percentage of lung volume compared to rats. 10 , 11 It may be that large animal models could help fill this gap in knowledge if the drug is administered for the duration corresponding to the same stage of lung development as in humans. This shortfall in rodent models also highlights the importance of the work of those who are creating human lung biorepositories or working to study respiratory function in preterm infants later in life. These efforts should be encouraged and supported in the future.
In this context, it is important to review the clinical use of corticosteroids in preterm neonates. Early systemic corticosteroids have been shown to be effective in reducing the rates of BPD at 36 weeks corrected gestational age (CGA). 12 A reduction in the combined outcome of death and BPD was noted but not the mortality rates alone at 36 weeks CGA. Of note, most of the impact of early systemic corticosteroids in reducing rates of BPD has been demonstrated by dexamethasone rather than hydrocortisone.
Early administration of systemic corticosteroids (less than 7 days after birth) has been reported some time ago to increase the rates of cerebral palsy in later childhood. However, interesting data came from one of the most influential trials of early systemic corticosteroids, the PREMILOC trial, using hydrocortisone. 13 , 14 Hydrocortisone reduced the rate of BPD or mortality at 36 weeks CGA, with no increase in the rates of cerebral palsy. 15 In fact, neurodevelopmental outcomes were actually better for the 24–25-week gestation cohort in the hydrocortisone group. In general, as we are adding more studies with lower and shorter steroid dosing, the negative effect on the brain is no longer being noted. The use of late systemic corticosteroids (administered >7 days after birth) reduces the rate of BPD, mortality, and combined outcome of mortality or BPD. 12 Similar to the early use of systemic corticosteroids, most of the effects of late systemic corticosteroids on BPD were with dexamethasone rather than hydrocortisone. Late systemic corticosteroids did not affect the rates of neurodevelopmental outcomes in later childhood.
The randomized clinical trial, SToP-BPD, studied the effect of systemic hydrocortisone, initiated between 7–14 days after birth in 372 infants. 16 No significant difference in the composite outcome of death or BPD was noted between the hydrocortisone and placebo groups; however, there was significantly lower mortality in the hydrocortisone group, with resultant higher BPD. Another RCT of the effect of hydrocortisone on survival without BPD and on adverse neurodevelopmental outcomes at 22–26 months of age in intubated infants <30 weeks gestational age also showed no difference in death/BPD or neurodevelopmental impairment but did show a lower rate of remaining intubated in the hydrocortisone group. 17 Recent meta-analyses of late (>7 days) starting of corticosteroids have continued to show benefit in reducing BPD without worse neurodevelopmental outcomes. In general, apart from a reduction in BPD, other beneficial effects of late systemic corticosteroids are lower rates of extubation failure and a smaller number of infants discharged home on oxygen. 12 One of the major limitations of both the early and late systemic corticosteroid trials was that most of the studies were not powered to detect significant neurodevelopmental differences between the corticosteroid and control groups, but this has improved by using meta-analysis approaches. 18
A knowledge gap perhaps still exists with the main finding of Lok et al. in terms of what alveolar simplification means to functional outcomes and lung/airway physiology (oxygen diffusion, exercise tolerance, susceptibility to respiratory infection, lung function studies) that are clinically important in the health outcomes of preterm children. 8 In addition, later stages of inflammation leading to a more severe form of BPD continues to be a problem with no clear therapy in sight. Corticosteroids may offer a ray of hope for such patients.
In summary, though there are reasonable data to support the use of corticosteroids to prevent BPD, there are likely detrimental effects to the developing lung, as suggested by the current Lok et al. paper, from corticosteroids that we give to our NICU patients. The authors made a critical point in their paper – the negative effects of steroids were greater in the normal lung control animals than in the injured animals. 8 It is possible that the dampening of inflammation by steroids has a greater positive effect than the negative effect on alveolar simplification for the relatively short-term BPD outcome. However, we do not know whether this is the case for later outcomes such as reactive airway disease, so commonly seen in NICU graduates, or even lung dysfunction much later in life.

Fall 2024 Semester
Undergraduate courses.
Composition courses that offer many sections (ENGL 101, 201, 277 and 379) are not listed on this schedule unless they are tailored to specific thematic content or particularly appropriate for specific programs and majors.
- 100-200 level
ENGL 151.S01: Introduction to English Studies
Tuesday and Thursday, 11 a.m.-12:15 p.m.
Sharon Smith
ENGL 151 serves as an introduction to both the English major and the discipline of English studies. In this class, you will develop the thinking, reading, writing and research practices that define both the major and the discipline. Much of the semester will be devoted to honing your literary analysis skills, and we will study and discuss texts from several different genres—poetry, short fiction, the novel, drama and film—as well as some literary criticism. As we do so, we will explore the language of the discipline, and you will learn a variety of key literary terms and concepts. In addition, you will develop your skills as both a writer and researcher within the discipline of English.
ENGL 201.ST1 Composition II: The Mind/Body Connection
In this section of English 201, students will use research and writing to learn more about problems that are important to them and articulate ways to address those problems. The course will focus specifically on issues related to the mind, the body and the relationship between them. The topics we will discuss during the course will include the correlation between social media and body image; the efficacy of sex education programs; the degree to which beliefs about race and gender influence school dress codes; and the unique mental and physical challenges faced by college students today. In this course, you will be learning about different approaches to argumentation, analyzing the arguments of others and constructing your own arguments. At the same time, you will be honing your skills as a researcher and developing your abilities as a persuasive and effective writer.
ENGL 201.S10 Composition II: Environmental Writing
Monday/Wednesday/Friday 1-1:50 p.m.
Gwen Horsley
English 201 will help students develop the ability to think critically and analytically and to write effectively for other university courses and careers. This course will provide opportunities to develop analytical skills that will help students become critical readers and effective writers. Specifically, in this class, students will:
- Focus on the relationships between world environments, land, animals and humankind.
- Read various essays by environmental, conservational and regional authors.
- Produce student writings.
Students will improve their writing skills by reading essays and applying techniques they witness in others’ work and those learned in class. This class is also a course in logical and creative thought. Students will write about humankind’s place in the world and our influence on the land and animals, places that hold special meaning to them or have influenced their lives and stories of their own families and their places and passions in the world. Students will practice writing in an informed and persuasive manner, in language that engages and enlivens readers by using vivid verbs and avoiding unnecessary passives, nominalizations and expletive constructions.
Students will prepare writing assignments based on readings and discussions of essays included in "Literature and the Environment " and other sources. They may use "The St. Martin’s Handbook," as well as other sources, to review grammar, punctuation, mechanics and usage as needed.
ENGL 201.13 Composition II: Writing the Environment
Tuesday and Thursday 9:30-10:45 a.m.
Paul Baggett
For generations, environmentalists have relied on the power of prose to change the minds and habits of their contemporaries. In the wake of fires, floods, storms and droughts, environmental writing has gained a new sense of urgency, with authors joining activists in their efforts to educate the public about the grim realities of climate change. But do they make a difference? Have reports of present and future disasters so saturated our airwaves that we no longer hear them? How do writers make us care about the planet amidst all the noise? In this course, students will examine the various rhetorical strategies employed by some of today’s leading environmental writers and filmmakers. And while analyzing their different arguments, students also will strengthen their own strategies of argumentation as they research and develop essays that explore a range of environmental concerns.
ENGL 201 Composition II: Food Writing
S17 Tuesday and Thursday 12:30-1:45 p.m.
S18 Tuesday and Thursday 2-3:15 p.m.
Jodi Andrews
In this composition class, students will critically analyze essays about food, food systems and environments, food cultures, the intersections of personal choice, market forces and policy and the values underneath these forces. Students will learn to better read like writers, noting authors’ purpose, audience organizational moves, sentence-level punctuation and diction. We will read a variety of essays including research-intensive arguments and personal narratives which intersect with one of our most primal needs as humans: food consumption. Students will rhetorically analyze texts, conduct advanced research, reflect on the writing process and write essays utilizing intentional rhetorical strategies. Through doing this work, students will practice the writing moves valued in every discipline: argument, evidence, concision, engaging prose and the essential research skills for the 21st century.
ENGL 221.S01 British Literature I
Michael S. Nagy
English 221 is a survey of early British literature from its inception in the Old English period with works such as "Beowulf" and the “Battle of Maldon,” through the Middle Ages and the incomparable writings of Geoffrey Chaucer and the Gawain - poet, to the Renaissance and beyond. Students will explore the historical and cultural contexts in which all assigned reading materials were written, and they will bring that information to bear on class discussion. Likely themes that this class will cover include heroism, humor, honor, religion, heresy and moral relativity. Students will write one research paper in this class and sit for two formal exams: a midterm covering everything up to that point in the semester, and a comprehensive final. Probable texts include the following:
- The Norton Anthology of English Literature: The Middle Ages. Ed. Alfred David, M. H. Abrams, and Stephen Greenblatt. 9th ed. New York: W. W. Norton & Company, 2012.
- The Norton Anthology of English Literature: The Sixteenth Century and Early Seventeenth Century. Ed. George M. Logan, Stephen Greenblatt, Barbara K Lewalski, and M. H. Abrams. 9th ed. New York: W. W. Norton & Company, 2012.
- The Norton Anthology of English Literature: The Restoration and the Eighteenth Century. Ed. George M. Logan, Stephen Greenblatt, Barbara K Lewalski, and M. H. Abrams. 9th ed. New York: W. W. Norton & Company, 2012.

ENGL 240.S01 Juvenile Literature Elementary-5th Grade
Monday, Wednesday and Friday noon-12:50 p.m.
April Myrick
A survey of the history of literature written for children and adolescents, and a consideration of the various types of juvenile literature. Text selection will focus on the themes of imagination and breaking boundaries.
ENGL 240.ST1 Juvenile Literature Elementary-5th Grade
Randi Anderson
In English 240 students will develop the skills to interpret and evaluate various genres of literature for juvenile readers. This particular section will focus on various works of literature at approximately the K-5 grade level. We will read a large range of works that fall into this category, as well as information on the history, development and genre of juvenile literature.
Readings for this course include classical works such as "Hatchet," "Little Women", "The Lion, the Witch and the Wardrobe" and "Brown Girl Dreaming," as well as newer works like "Storm in the Barn," "Anne Frank’s Diary: A Graphic Adaptation," "Lumberjanes," and a variety of picture books. These readings will be paired with chapters from "Reading Children’s Literature: A Critical Introduction " to help develop understanding of various genres, themes and concepts that are both related to juvenile literature and also present in our readings.
In addition to exposing students to various genres of writing (poetry, historical fiction, non-fiction, fantasy, picture books, graphic novels, etc.) this course will also allow students to engage in a discussion of larger themes present in these works such as censorship, race and gender. Students’ understanding of these works and concepts will be developed through readings, research, discussion posts, exams and writing assignments designed to get students to practice analyzing poetry, picture books, informational books and transitional/easy readers.
ENGL 241.S01: American Literature I
Tuesday and Thursday 12:30-1:45 p.m.
This course provides a broad, historical survey of American literature from the early colonial period to the Civil War. Ranging across historical periods and literary genres—including early accounts of contact and discovery, narratives of captivity and slavery, poetry of revolution, essays on gender equality and stories of industrial exploitation—this class examines how subjects such as colonialism, nationhood, religion, slavery, westward expansion, race, gender and democracy continue to influence how Americans see themselves and their society.
Required Texts
- The Norton Anthology of American Literature: Package 1, Volumes A and B Beginnings to 1865, Ninth Edition. (ISBN 978-0-393-26454-8)
ENGL 283.S01 Introduction to Creative Writing
Steven Wingate
Students will explore the various forms of creative writing (fiction, nonfiction and poetry) not one at a time in a survey format—as if there were decisive walls of separation between then—but as intensely related genres that share much of their creative DNA. Through close reading and work on personal texts, students will address the decisions that writers in any genre must face on voice, rhetorical position, relationship to audience, etc. Students will produce and revise portfolios of original creative work developed from prompts and research. This course fulfills the same SGR #2 requirements ENGL 201; note that the course will involve a research project. Successful completion of ENGL 101 (including by test or dual credit) is a prerequisite.
ENGL 283.S02 Introduction to Creative Writing
Jodilyn Andrews
This course introduces students to the craft of writing, with readings and practice in at least two genres (including fiction, poetry and drama).
ENGL 283.ST1 Introduction to Creative Writing
Amber Jensen, M.A., M.F.A.
This course explores creative writing as a way of encountering the world, research as a component of the creative writing process, elements of craft and their rhetorical effect and drafting, workshop and revision as integral parts of writing polished literary creative work. Student writers will engage in the research practices that inform the writing of literature and in the composing strategies and writing process writers use to create literary texts. Through their reading and writing of fiction, poetry and creative nonfiction, students will learn about craft elements, find examples of those craft elements in published works and apply these elements in their own creative work, developed through weekly writing activities, small group and large group workshop and conferences with the instructor. Work will be submitted, along with a learning reflection and revision plan in each genre and will then be revised and submitted as a final portfolio at the end of the semester to demonstrate continued growth in the creation of polished literary writing.
- 300-400 level
ENGL 424.S01 Language Arts Methods grades 7-12
Tuesday 6-8:50 p.m.
Danielle Harms
Techniques, materials and resources for teaching English language and literature to middle and secondary school students. Required of students in the English education option.
AIS/ENGL 447.S01: American Indian Literature of the Present
Thursdays 3-6 p.m.
This course introduces students to contemporary works by authors from various Indigenous nations. Students examine these works to enhance their historical understanding of Indigenous peoples, discover the variety of literary forms used by those who identify as Indigenous writers, and consider the cultural and political significance of these varieties of expression. Topics and questions to be explored include:
- Genre: What makes Indigenous literature indigenous?
- Political and Cultural Sovereignty: Why have an emphasis on tribal specificity and calls for “literary separatism” emerged in recent decades, and what are some of the critical conversations surrounding such particularized perspectives?
- Gender and Sexuality: What are the intersecting concerns of Indigenous Studies and Women, Gender and Sexuality Studies, and how might these research fields inform one another?
- Trans-Indigeneity: What might we learn by comparing works across different Indigenous traditions, and what challenges do such comparisons present?
- Aesthetics: How do Indigenous writers understand the dynamics between tradition and creativity?
- Visual Forms: What questions or concerns do visual representations (television and film) by or about Indigenous peoples present?

ENGL 472.S01: Film Criticism
Tuesdays 2-4:50 p.m.
Jason McEntee
Do you have an appreciation for, and enjoy watching, movies? Do you want to study movies in a genre-oriented format (such as those we typically call the Western, the screwball comedy, the science fiction or the crime/gangster, to name a few)? Do you want to explore the different critical approaches for talking and writing about movies (such as auteur, feminist, genre or reception)?
In this class, you will examine movies through viewing and defining different genres while, at the same time, studying and utilizing different styles of film criticism. You will share your discoveries in both class discussions and short writings. The final project will be a formal written piece of film criticism based on our work throughout the semester. The course satisfies requirements and electives for all English majors and minors, including both the Film Studies and Professional Writing minors. (Note: Viewing of movies outside of class required and may require rental and/or streaming service fees.)
ENGL 476.ST1: Fiction
In this workshop-based creative writing course, students will develop original fiction based on strong attention to the fundamentals of literary storytelling: full-bodied characters, robust story lines, palpable environments and unique voices. We will pay particular attention to process awareness, to the integrity of the sentence, and to authors' commitments to their characters and the places in which their stories unfold. Some workshop experience is helpful, as student peer critique will be an important element of the class.
ENGL 479.01 Capstone: The Gothic
Wednesday 3-5:50 p.m.
With the publication of Horace Walpole’s "The Castle of Otranto " in 1764, the Gothic officially came into being. Dark tales of physical violence and psychological terror, the Gothic incorporates elements such as distressed heroes and heroines pursued by tyrannical villains; gloomy estates with dark corridors, secret passageways and mysterious chambers; haunting dreams, troubling prophecies and disturbing premonitions; abduction, imprisonment and murder; and a varied assortment of corpses, apparitions and “monsters.” In this course, we will trace the development of Gothic literature—and some film—from the eighteenth-century to the present time. As we do so, we will consider how the Gothic engages philosophical beliefs about the beautiful and sublime; shapes psychological understandings of human beings’ encounters with horror, terror, the fantastic and the uncanny; and intervenes in the social and historical contexts in which it was written. We’ll consider, for example, how the Gothic undermines ideals related to domesticity and marriage through representations of domestic abuse, toxicity and gaslighting. In addition, we’ll discuss Gothic texts that center the injustices of slavery and racism. As many Gothic texts suggest, the true horrors of human existence often have less to do with inexplicable supernatural phenomena than with the realities of the world in which we live.
ENGL 485.S01: Undergraduate Writing Center Learning Assistants
Flexible Scheduling
Nathan Serfling
Since their beginnings in the 1920s and 30s, writing centers have come to serve numerous functions: as hubs for writing across the curriculum initiatives, sites to develop and deliver workshops and resource centers for faculty as well as students, among other functions. But the primary function of writing centers has necessarily and rightfully remained the tutoring of student writers. This course will immerse you in that function in two parts. During the first four weeks, you will explore writing center praxis—that is, the dialogic interplay of theory and practice related to writing center work. This part of the course will orient you to writing center history, key theoretical tenets and practical aspects of writing center tutoring. Once we have developed and practiced this foundation, you will begin work in the writing center as a tutor, responsible for assisting a wide variety of student clients with numerous writing tasks. Through this work, you will learn to actively engage with student clients in the revision of a text, respond to different student needs and abilities, work with a variety of writing tasks and rhetorical situations, and develop a richer sense of writing as a complex and negotiated social process.
Graduate Courses
Engl 572.s01: film criticism, engl 576.st1 fiction.
In this workshop-based creative writing course, students will develop original fiction based on strong attention to the fundamentals of literary storytelling: full-bodied characters, robust story lines, palpable environments and unique voices. We will pay particular attention to process awareness, to the integrity of the sentence and to authors' commitments to their characters and the places in which their stories unfold. Some workshop experience is helpful, as student peer critique will be an important element of the class.
ENGL 605.S01 Seminar in Teaching Composition
Thursdays 1-3:50 p.m.
This course will provide you with a foundation in the pedagogies and theories (and their attendant histories) of writing instruction, a foundation that will prepare you to teach your own writing courses at SDSU and elsewhere. As you will discover through our course, though, writing instruction does not come with any prescribed set of “best” practices. Rather, writing pedagogies stem from and continue to evolve because of various and largely unsettled conversations about what constitutes effective writing and effective writing instruction. Part of becoming a practicing writing instructor, then, is studying these conversations to develop a sense of what “good writing” and “effective writing instruction” might mean for you in our particular program and how you might adapt that understanding to different programs and contexts.
As we read about, discuss and research writing instruction, we will address a variety of practical and theoretical topics. The practical focus will allow us to attend to topics relevant to your immediate classroom practices: designing a curriculum and various types of assignments, delivering the course content and assessing student work, among others. Our theoretical topics will begin to reveal the underpinnings of these various practical matters, including their historical, rhetorical, social and political contexts. In other words, we will investigate the praxis—the dialogic interaction of practice and theory—of writing pedagogy. As a result, this course aims to prepare you not only as a writing teacher but also as a nascent writing studies/writing pedagogy scholar.
At the end of this course, you should be able to engage effectively in the classroom practices described above and participate in academic conversations about writing pedagogy, both orally and in writing. Assessment of these outcomes will be based primarily on the various writing assignments you submit and to a smaller degree on your participation in class discussions and activities.
ENGL 726.S01: The New Woman, 1880–1900s
Thursdays 3–5:50 p.m.
Katherine Malone
This course explores the rise of the New Woman at the end of the nineteenth century. The label New Woman referred to independent women who rebelled against social conventions. Often depicted riding bicycles, smoking cigarettes and wearing masculine clothing, these early feminists challenged gender roles and sought broader opportunities for women’s employment and self-determination. We will read provocative fiction and nonfiction by New Women writers and their critics, including authors such as Sarah Grand, Mona Caird, George Egerton, Amy Levy, Ella Hepworth Dixon, Grant Allen and George Gissing. We will analyze these exciting texts through a range of critical lenses and within the historical context of imperialism, scientific and technological innovation, the growth of the periodical press and discourse about race, class and gender. In addition to writing an argumentative seminar paper, students will complete short research assignments and lead discussion.
ENGL 792.ST1 Women in War: Female Authors and Characters in Contemporary War Lit
In this course, we will explore the voices of female authors and characters in contemporary literature of war. Drawing from various literary theories, our readings and discussion will explore the contributions of these voices to the evolving literature of war through archetypal and feminist criticism. We will read a variety of short works (both theoretical and creative) and complete works such as (selections subject to change): "Eyes Right" by Tracy Crow, "Plenty of Time When We Get Home" by Kayla Williams, "You Know When the Men are Gone" by Siobhan Fallon, "Still, Come Home" by Katie Schultz and "The Fine Art of Camouflage" by Lauren Johnson.
