Peer review is the evaluation of work by one or more people with similar competencies as the producers of the work. It functions as a form of self-regulation by qualified members of a profession within the relevant field. Peer review methods are used to maintain quality standards, improve performance, and provide credibility. In academia, scholarly peer review is often used to determine an academic paper's suitability for publication. Peer review can be categorized by the type of activity and by the field or profession in which the activity occurs, e.g., medical peer review. It can also be used as a teaching tool to help students improve writing assignments.
In academic publishing, a scientific journal is a periodical publication intended to further the progress of science, usually by sharing findings from research with readers. They are normally specialized based on discipline, with authors picking which one they send their manuscripts to.
Proceedings of the National Academy of Sciences of the United States of America is a peer-reviewed multidisciplinary scientific journal. It is the official journal of the National Academy of Sciences, published since 1915, and publishes original research, scientific reviews, commentaries, and letters. According to Journal Citation Reports, the journal has a 2021 impact factor of 12.779. PNAS is the second most cited scientific journal, with more than 1.9 million cumulative citations from 2008 to 2018. In the mass media, PNAS has been described variously as "prestigious", "sedate", "renowned" and "high impact".
Academic publishing is the subfield of publishing which distributes academic research and scholarship. Most academic work is published in academic journal articles, books or theses. The part of academic written output that is not formally published but merely printed up or posted on the Internet is often called "grey literature". Most scientific and scholarly journals, and many academic and scholarly books, though not all, are based on some form of peer review or editorial refereeing to qualify texts for publication. Peer review quality and selectivity standards vary greatly from journal to journal, publisher to publisher, and field to field.
An academic journal or scholarly journal is a periodical publication in which scholarship relating to a particular academic discipline is published. Academic journals serve as permanent and transparent forums for the presentation, scrutiny, and discussion of research. They nearly universally require peer review or other scrutiny from contemporaries competent and established in their respective fields. Content typically takes the form of articles presenting original research, review articles, or book reviews. The purpose of an academic journal, according to Henry Oldenburg, is to give researchers a venue to "impart their knowledge to one another, and contribute what they can to the Grand design of improving natural knowledge, and perfecting all Philosophical Arts, and Sciences."
Open access (OA) is a set of principles and a range of practices through which research outputs are distributed online, free of access charges or other barriers. Under some models of open access publishing, barriers to copying or reuse are also reduced or removed by applying an open license for copyright.
Scientific literature comprises academic papers that report original empirical and theoretical work in the natural and social sciences. Within a field of research, relevant papers are often referred to as "the literature". Academic publishing is the process of contributing the results of one's research into the literature, which often requires a peer-review process.
A public health journal is a scientific journal devoted to the field of public health, including epidemiology, biostatistics, and health care. Public health journals, like most scientific journals, are peer-reviewed. Public health journals are commonly published by health organizations and societies, such as the Bulletin of the World Health Organization or the Journal of Epidemiology and Community Health. Many others are published by a handful of large publishing corporations that includes Elsevier, Wolters Kluwer, Wiley-Blackwell, Springer Science+Business Media, and Informa, each of which has many imprints. Many societies partner with such corporations to handle the work of producing their journals.
Stephen Joel Barrett is an American retired psychiatrist, author, co-founder of the National Council Against Health Fraud (NCAHF), and the webmaster of Quackwatch. He runs a number of websites dealing with quackery and health fraud. He focuses on consumer protection, medical ethics, and scientific skepticism.
The impact factor (IF) or journal impact factor (JIF) of an academic journal is a scientometric index calculated by Clarivate that reflects the yearly mean number of citations of articles published in the last two years in a given journal, as indexed by Clarivate's Web of Science.
PLOS One is a peer-reviewed open access mega journal published by the Public Library of Science (PLOS) since 2006. The journal covers primary research from any discipline within science and medicine. The Public Library of Science began in 2000 with an online petition initiative by Nobel Prize winner Harold Varmus, formerly director of the National Institutes of Health and at that time director of Memorial Sloan–Kettering Cancer Center; Patrick O. Brown, a biochemist at Stanford University; and Michael Eisen, a computational biologist at the University of California, Berkeley, and the Lawrence Berkeley National Laboratory.
Medical Hypotheses is a not-conventionally-peer-reviewed medical journal published by Elsevier. It was originally intended as a forum for unconventional ideas without the traditional filter of scientific peer review, "as long as are coherent and clearly expressed" in order to "foster the diversity and debate upon which the scientific process thrives." The publication of papers on AIDS denialism led to calls to remove it from PubMed, the United States National Library of Medicine online journal database. Following the AIDS papers controversy, Elsevier forced a change in the journal's leadership. In June 2010, Elsevier announced that "submitted manuscripts will be reviewed by the Editor and external reviewers to ensure their scientific merit".
A review article is an article that summarizes the current state of understanding on a topic within a certain discipline. A review article is generally considered a secondary source since it may analyze and discuss the method and conclusions in previously published studies. It resembles a survey article or, in news publishing, overview article, which also surveys and summarizes previously published primary and secondary sources, instead of reporting new facts and results. Survey articles are however considered tertiary sources, since they do not provide additional analysis and synthesis of new conclusions. A review of such sources is often referred to as a tertiary review.
MDPI is a publisher of open access scientific journals. Founded by Shu-Kun Lin as a chemical sample archive, it now publishes over 390 peer-reviewed, open access journals. MDPI is among the largest publishers in the world in terms of journal article output, and is the largest publisher of open access articles.
PatientsLikeMe is an integrated community, health management, and real-world data platform. The platform currently has over 830,000 members who are dealing with more than 2,900 conditions. Data generated by patients themselves are systemically collected and quantified with the goal of providing an environment for peer support and learning. These data capture the complex temporality and competing influences of different lifestyle choices, socio-demographics, conditions and treatments on a person's health. While striving to empower the community with personal agency, PLM has also established itself as a clinical resource with more than 100 studies in peer-reviewed medical and scientific journals.
Scientific Reports is a peer-reviewed open-access scientific mega journal published by Nature Portfolio, covering all areas of the natural sciences. The journal was established in 2011. The journal states that their aim is to assess solely the scientific validity of a submitted paper, rather than its perceived importance, significance, or impact.
Scholarly peer review or academic peer review is the process of having a draft version of a researcher's methods and findings reviewed by experts in the same field. Peer review is widely used for helping the academic publisher decide whether the work should be accepted, considered acceptable with revisions, or rejected for official publication in an academic journal, a monograph or in the proceedings of an academic conference. If the identities of authors are not revealed to each other, the procedure is called dual-anonymous peer review.
The replication crisis is an ongoing methodological crisis in which the results of many scientific studies are difficult or impossible to reproduce. Because the reproducibility of empirical results is an essential part of the scientific method, such failures undermine the credibility of theories building on them and potentially call into question substantial parts of scientific knowledge.
Preregistration is the practice of registering the hypotheses, methods, and/or analyses of a scientific study before it is conducted. Clinical trial registration is similar, although it may not require the registration of a study's analysis protocol. Finally, registered reports include the peer review and in principle acceptance of a study protocol prior to data collection.
