The journal investigates studies in Sleep in non-human animals, Internal medicine, Audiology, Polysomnography and Anesthesia. Sleep in non-human animals research featured in it incorporates concerns from various other topics such as Insomnia and Electroencephalography. Topics in Insomnia were tackled in line with various other fields like Sleep disorder and Clinical psychology.

The concepts on Internal medicine presented in Journal of Sleep Research can also apply to other research fields, including Endocrinology and Cardiology. The studies on Audiology discussed can also contribute to research in the domains of Cognition, Sleep onset, Developmental psychology, Wakefulness and Eye movement. The studies in Polysomnography featured incorporate elements of Rapid eye movement sleep, Physical therapy and Actigraphy.

The Anesthesia study featured in it draws connections with the study of Arousal. Non-rapid eye movement sleep research discussed connects with the study of Slow-wave sleep. The Circadian rhythm study featured in Journal of Sleep Research draws parallels with the field of Melatonin.

The aim of the journal is to expand the discussion of research in Sleep in non-human animals, Insomnia, Clinical psychology, Internal medicine and Polysomnography. While it focused on Sleep in non-human animals, it was also able to explore topics like Cognition and Audiology. Eye movement and Electroencephalography are some topics wherein Audiology research discussed in Journal of Sleep Research have an impact.

Topics in Insomnia explored in it were investigated in conjunction with research in Meta-analysis, Sleep hygiene, Sleep disorder and Randomized controlled trial. Issues in Internal medicine were discussed, taking into consideration concepts from other disciplines like Endocrinology and Cardiology. The overlapping concepts between Obstructive sleep apnea and Epworth Sleepiness Scale are the key highlights of Polysomnography study.

Publication chance based on affiliation

The publication chance index shows the ratio of articles published by the best research institutions in the journal edition to all articles published within that journal. The best research institutions were selected based on the largest number of articles published during all editions of the journal.

The chart below presents the percentage ratio of articles from top institutions (based on their ranking of total papers).Top affiliations were grouped by their rank into the following tiers: top 1-10, top 11-20, top 21-50, and top 51+. Only articles with a recognized affiliation are considered.

During the most recent 2021 edition, 2.90% of publications had an unrecognized affiliation. Out of the publications with recognized affiliations, 16.61% were posted by at least one author from the top 10 institutions publishing in the journal. Another 12.62% included authors affiliated with research institutions from the top 11-20 affiliations. Institutions from the 21-50 range included 22.92% of all publications and 47.84% were from other institutions.

Returning Authors Index

A very common phenomenon observed among researchers publishing scientific articles is the intentional selection of journals they have already attended in the past. In particular, it is worth analyzing the case when the authors participate in the same journal from year to year.

The Returning Authors Index presented below illustrates the ratio of authors who participated in both a given as well as the previous edition of the journal in relation to all participants in a given year.

Returning Institution Index

The graph below shows the Returning Institution Index, illustrating the ratio of institutions that participated in both a given and the previous edition of the conference in relation to all affiliations present in a given year.

The experience to innovation index

Our experience to innovation index was created to show a cross-section of the experience level of authors publishing in a journal. The index includes the authors publishing at the last edition of a journal, grouped by total number of publications throughout their academic career (P) and the total number of citations of these publications ever received (C).

The group intervals were selected empirically to best show the diversity of the authors' experiences, their labels were selected as a convenience, not as judgment. The authors were divided into the following groups:

  • Novice - P < 5 or C < 25 (the number of publications less than 5 or the number of citations less than 25),
  • Competent - P < 10 or C < 100 (the number of publications less than 10 or the number of citations less than 100),
  • Experienced - P < 25 or C < 625 (the number of publications less than 25 or the number of citations less than 625),
  • Master - P < 50 or C < 2500 (the number of publications less than 50 or the number of citations less than 2500),
  • Star - P ≥ 50 and C ≥ 2500 (both the number of publications greater than 50 and the number of citations greater than 2500).

The chart below illustrates experience levels of first authors in cases of publications with multiple authors.

Career Opportunities and Guidelines for Aspiring Sleep Researchers

For readers who are intrigued by the research topics and studies discussed in the article and interested to contribute in this field, it's important to understand the career opportunities and academic path towards becoming a sleep researcher. In general, the pathway requires a dedication towards scientific study, ideally starting with a bachelor's degree in psychology, biology, neuroscience, or a related field. A focused master’s program and doctoral study usually follow this. IT is also crucial to gain practical experience through internships and research programs.

Furthermore, having a specialization or an area of interest can provide direction for your career path. For instance, one might choose to specialize in the effects of sleep deprivation on cognitive performance, studying sleep patterns in non-human animals, or examining the link between sleep and audiology. These specialized fields often require advanced degrees and a deep understanding of both sleep science and the specific field of interest.

If you are particularly interested in pursuing a career in the area of audiology with a focus on speech pathology, you can consider becoming a licensed Speech-Language Pathologist. Specifically, those based in Wisconsin can follow the speech pathologist requirements in Wisconsin. This career involves assessing, diagnosing, and treating communication and swallowing disorders, and could intersect with sleep research through the study of sleep apnea, snoring, and other sleep disorders that affect speech and language.

In conclusion, sleep research is an expansive field with numerous career paths that lay the foundation for breakthrough discoveries and improving people's quality of life through better sleep.
