Introduction

This is a Distant Reader "study carrel", a set of structured data intended to help the student, researcher, or scholar use & understand a corpus.

This study carrel was created on 2021-05-25 by Eric Morgan <emorgan@nd.edu>. The carrel was created using the Distant Reader cord process, and the input was the result of a query applied to a local mirror of CORD, a data set of scholarly articles on the topic of COVID-19. The actual query was: keywords:stress. The results of this query were saved in a cache and transformed into a set of plain text files. All of the analysis -- "reading" -- has been done against these plain text files. For example, a short narrative report has been created. This Web page is a more verbose version of that report.

All study carrels are self-contained -- no Internet connection is necessary to use them. Download this carrel for offline reading. The carrel is made up of many subdirectories and data files. The manifest describes each one in greater detail.

Size

There are 50 item(s) in this carrel, and this carrel is 166,541 words long. Each item in your study carrel is, on average, 9,796 words long. If you dig deeper, then you might want to save yourself some time by reading a shorter item. On the other hand, if your desire is for more detail, then you might consider reading a longer item. The following charts illustrate the overall size of the carrel.

Readability

On a scale from 0 to 100, where 0 is very difficult and 100 is very easy, the documents have an average readability score of 45. Consequently, if you want to read something more simplistic, then consider a document with a higher score. If you want something more specialized, then consider something with a lower score. The following charts illustrate the overall readability of the carrel.

Word Frequencies

By merely counting & tabulating the frequency of individual words or phrases, you can begin to get an understanding of the carrel's "aboutness". Excluding "stop words", some of the more frequent words include:

stress, health, covid, may, study, depression, cats, also, anxiety, response, disease, related, psychological, social, coping, factors, levels, risk, associated, high, protein, studies, mental, pandemic, among, well, symptoms, cells, used, effects, women, perceived, cell, work, time, immune, analysis, responses, use, higher, chronic, proteins, infection, level, one, control, increased, based, population, sg

Using the three most frequent words, the three files containing all of those words the most are Psychological, addictive, and health behavior implications of the COVID-19 pandemic, Targeting stress granules: A novel therapeutic strategy for human diseases, and The geroscience agenda: What does stress have to do with it?.

The most frequent two-word phrases (bigrams) include:

mental health, perceived stress, coping strategies, stress response, posttraumatic stress, stress granules, oxidative stress, sg assembly, chronic stress, social support, systematic review, immune system, health care, traumatic stress, depressive symptoms, united states, risk factors, psychological stress, stress granule, stress levels, medical students, pregnant women, sg formation, immune response, heat shock, stress disorder, psychological distress, social isolation, gene expression, coronavirus disease, er stress, stress responses, endoplasmic reticulum, heat stress, present study, high levels, innate immune, general population, related stress, healthcare workers, respiratory syndrome, public health, higher levels, infectious disease, cell death, doc id, immune responses, cord uid, acute respiratory, novel coronavirus

And the three file that use all of the three most frequent phrases are Predicting Perceived Stress Related to the Covid-19 Outbreak through Stable Psychological Traits and Machine Learning Models The relationship between perceived stress and emotional distress during the COVID-19 outbreak: Effects of boredom proneness and coping style, and Stress and Parenting during the Global COVID-19 Pandemic.

While often deemed superficial or sophomoric, rudimentary frequencies and their associated "word clouds" can be quite insightful:

Keywords

Sets of keywords -- statistically significant words -- can be enumerated by comparing the relative frequency of words with the number of times the words appear in an entire corpus. Some of the most statistically significant keywords in the carrel include:

stress, covid-19, depression, response, protein, disease, anxiety, work, rna, health, cell, woman, study, shelter, ptsd, pregnancy, hpa, dna, cat, animal, age, welfare, vegf, upr, united, twitter, tweet, treatment, traumatic, tool, time, tia-1, teacher, tdp-43, taiwan, table, supplementary, student, stressor, strategy, states, social, small, sgs, sexual, school, sars, safety, ros, risk

And now word clouds really begin to shine:

Topic Modeling

Topic modeling is another popular approach to connoting the aboutness of a corpus. If the study carrel could be summed up in a single word, then that word might be stress, and Stress and Parenting during the Global COVID-19 Pandemic is most about that word.

If the study carrel could be summed up in three words ("topics") then those words and their significantly associated titles include:

  1. stress - Population Wellness: Keeping Cats Physically and Behaviorally Healthy
  2. stress - The type of stress matters: repeated injection and permanent social isolation stress in male mice have a differential effect on anxiety- and depressive-like behaviours, and associated biological alterations
  3. stress - Cell-Autonomous (Cell-Intrinsic) Stress Responses

If the study carrel could be summed up in five topics, and each topic were each denoted with three words, then those topics and their most significantly associated files would be:

  1. stress, cats, health - Population Wellness: Keeping Cats Physically and Behaviorally Healthy
  2. stress, immune, response - The type of stress matters: repeated injection and permanent social isolation stress in male mice have a differential effect on anxiety- and depressive-like behaviours, and associated biological alterations
  3. stress, protein, sg - Cell-Autonomous (Cell-Intrinsic) Stress Responses
  4. stress, coping, covid - Impact of the COVID-19 pandemic on mental health in the general Chinese population: Changes, predictors and psychosocial correlates
  5. stress, depression, ptsd - Social, cultural, and other diversity issues in the traumatic stress field

Noun & Verbs

Through an analysis of your study carrel's parts-of-speech, you are able to answer question beyonds aboutness. For example, a list of the most frequent nouns helps you answer what questions; "What is discussed in this collection?":

stress, health, depression, study, cats, response, anxiety, disease, levels, factors, risk, studies, protein, symptoms, cells, pandemic, effects, women, cell, time, responses, students, proteins, level, analysis, work, infection, population, patients, data, results, life, system, research, role, participants, control, factor, animal, treatment, stressors, strategies, care, use, people, support, model, exposure, group, impact

An enumeration of the verbs helps you learn what actions take place in a text or what the things in the text do. Very frequently, the most common lemmatized verbs are "be", "have", and "do"; the more interesting verbs usually occur further down the list of frequencies:

using, included, increased, related, cope, associated, shown, induce, perceived, found, provided, based, reported, reduce, leads, identified, involved, assess, affected, develop, compared, followed, experienced, regulated, caused, indicated, promoting, suggesting, seen, require, mediating, result, considered, aging, signaling, binds, measure, described, activate, contribute, made, known, becoming, given, focus, decreases, take, prevent, work, improved

Proper Nouns

An extraction of proper nouns helps you determine the names of people and places in your study carrel.

COVID-19, SGs, SG, Stress, ER, Health, SARS, PTSD, Table, J, RNA, •, Fig, China, United, States, ROS, HPA, mRNA, C, TIA-1, T, Supplementary, Association, HIV, PBs, American, A, UPR, Nrf2, University, VEGF, Disease, Anxiety, PHQ, Mental, March, sha, World, Study, II, CoV-2, ATP, PH, U.S., H69, Analysis, Review, Group, Coronavirus

An analysis of personal pronouns enables you to answer at least two questions: 1) "What, if any, is the overall gender of my study carrel?", and 2) "To what degree are the texts in my study carrel self-centered versus inclusive?"

it, their, we, they, its, our, them, i, you, her, she, your, themselves, one, us, his, itself, he, my, yourself, me, him, himself, oneself, myself, herself, 's, ζ, ourselves, mrnas, m, i18rlo2r, cums

Below are words cloud of your study carrel's proper & personal pronouns.
