bibliometrix-assisted bibliometric analysis is a structured quantitative approach to mapping a scientific field using the bibliometrix R package. Developed by Aria and Cuccurullo (2017), it provides an integrated environment for importing bibliographic records from Scopus or Web of Science, computing performance indica
Co-word analysis is a scientometric technique that quantifies how often pairs of keywords, subject terms, or title words appear together across a corpus of publications. By treating simultaneous occurrence as a proxy for conceptual relatedness, it constructs networks and clusters that reveal the intellectual structure,
Idea plagiarism, or conceptual plagiarism, occurs when an author takes another's ideas, arguments, theories, or conceptual frameworks and presents them as original work without crediting the source. Unlike verbatim or paraphrasing plagiarism (which involve copying language), idea plagiarism involves taking the intellec
Thematic evolution analysis is a bibliometric technique that divides a body of literature into consecutive time periods and tracks how research themes emerge, consolidate, split, merge, or disappear across those periods. By combining co-word analysis, clustering, and strategic diagrams for each time slice, it produces
An abstract is a self-contained, concise summary of a research article that enables readers to quickly understand the study's purpose, methods, results, and conclusions without reading the full paper. Abstracts are the primary gateway to published literature: they appear in journal issues, bibliographic databases (MEDL
Altmetrics (alternative metrics) measure the online attention and societal impact of research by tracking mentions in social media (Twitter), news outlets, policy documents, blogs, videos, and other online sources. Introduced formally in 2010 by Jason Priem and colleagues, altmetrics address limitations of citation-bas
The 3Rs (Replacement, Reduction, Refinement) is the ethical framework governing humane animal research, established by Russell and Burch (1959) and now adopted globally by research institutions, funding agencies, and regulatory bodies. The 3Rs require researchers to: replace animal research with non-animal methods wher
APA (American Psychological Association) Style is a citation and formatting standard widely used in psychology, education, social sciences, and increasingly in health sciences. APA uses author-date in-text citations (e.g., Smith, 2021) linked to a reference list at the end of the manuscript. The 7th edition (2020) is t
An article retraction is the invalidation of a published article due to serious flaws (data fraud, major methodological errors, ethical violations) that undermine its conclusions. Retractions are distinct from corrections (which address minor errors) and are initiated by authors, editors, or institutions when integrity
The Belmont Report (1979) is the foundational US ethical framework for human subjects research, established by the National Commission following the Tuskegee Syphilis Study scandal. It articulates three core principles—Respect for Persons, Beneficence, and Justice—that form the basis for institutional review and regula
Bibliographic coupling is a method that identifies intellectual relationships between documents by measuring their shared references. Two papers are considered 'coupled' when they cite the same sources, indicating they address related research questions or draw from the same conceptual foundations. Introduced by Kessle
Bibliometric analysis applies statistical and mathematical methods to bibliographic records — publications, citations, authors, journals, and keywords — to measure and map the structure, output, and intellectual evolution of a research field. It is widely used to identify influential works, prolific authors, productive
Three foundational empirical laws describe the structure and distribution of scientific information: Lotka's Law characterizes author productivity (most authors publish few papers; a few publish many), Bradford's Law describes journal concentration (a small number of core journals contain the majority of papers on a to
Bibliometrix-assisted bibliographic coupling applies the open-source R package bibliometrix to construct and analyse bibliographic coupling networks, in which two documents are linked by the number of references they share. The workflow automates record import, network construction, community detection, and summary sta

By combining co-word analysis with strategic diagram visualisation, the workflow maps the intellectual structure
A book chapter is an original scholarly contribution comprising a single chapter within an edited academic volume (book). Unlike journal articles (independent publications in a periodical), book chapters are integrated parts of a larger work edited by one or more scholars. Book chapters allow greater length (5,000–15,0
Boolean search operators are logical functions—AND, OR, NOT, and parentheses—used to combine and filter search terms in bibliographic databases, library catalogs, and search engines. Named after mathematician George Boole (1815–1864), Boolean logic has been applied to information retrieval since the 1960s. These operat
A case report is a detailed clinical account of one patient's diagnosis, treatment, and outcome, typically used to describe novel, unusual, or educational cases not previously reported. Unlike controlled studies with comparison groups, case reports are observational, non-comparative, and generate hypotheses rather than
Citation analysis is the systematic study of how scholarly works are cited by subsequent research, used as a proxy for research impact and influence. Founded formally by Eugene Garfield in 1955 (introducing citation indexes), the field encompasses metrics ranging from simple citation counts to sophisticated indices lik
Citation management tools are software applications that store, organize, and format bibliographic references. They allow researchers to import citations from databases and websites, annotate and tag articles, organize references by project, and automatically generate formatted in-text citations and bibliographies in m
Clinical trial registration is the prospective documentation of a trial's key information (hypothesis, design, population, outcomes) in a public registry before enrollment begins or results are known. In 2005, the World Health Organization established the requirement that all clinical trials be registered in an interna
Co-authorship network analysis is a method that maps research collaboration patterns by treating authors as nodes and co-authored papers as edges in a network graph. The structure, density, and centrality patterns of this network reveal how researchers connect, collaborate across institutions and disciplines, and form
Co-citation analysis is a method that identifies the intellectual structure of a research domain by examining how frequently pairs of documents are cited together in other publications. When two papers are frequently cited together in the literature, they are considered co-cited, indicating they are conceptually relate
A conference paper is original research presented at an academic conference, typically via oral presentation or poster. Conference papers are published in proceedings (collection of papers from a conference) and indexed in databases (Scopus, Web of Science). Unlike journal articles requiring 12–24 months for publicatio
A conflict of interest (COI) in research exists when a researcher has financial, professional, or personal interests that might bias their research judgment or outcomes. Conflicts are inherent in research communities—researchers often have legitimate stakes in their research's success—but unmanaged conflicts compromise
The Committee on Publication Ethics (COPE), founded in 1997, is an international organization of journal editors and publishers that promotes and advances research integrity and publication ethics. COPE provides practical guidance through flowcharts, position statements, and ethical guidelines addressing misconduct (fa
Data fabrication and falsification are serious forms of research misconduct involving intentional misrepresentation of research data. Fabrication means inventing data that were never actually collected; falsification means altering authentic data to change the meaning. Both undermine scientific integrity, waste researc
Research involving human subjects generates sensitive data: medical records, genetic information, behavioral responses, economic or social information. Regulatory frameworks—HIPAA (Health Insurance Portability and Accountability Act) in the U.S., GDPR (General Data Protection Regulation) in the European Union, and para
Data sharing and open science are practices that maximize research transparency and reproducibility by making raw data, analysis code, and methods publicly available alongside publications. The replication crisis (widespread failure to reproduce published findings in psychology, medicine, and other fields) revealed tha
Deception in research—withholding information about study procedures, hypotheses, or true purpose—is ethically permissible under limited circumstances when specific criteria are met. The regulatory framework (45 CFR 46.116(a)(5) in the U.S.; APA Ethical Code Section 8.07) allows deception if: (1) it is not reasonably p
The Declaration of Helsinki (1964) is the foundational international ethical code for medical research involving human subjects, established by the World Medical Association. It extended earlier principles (Nuremberg Code 1947) to include therapeutic research and formalized the physician's ethical duty to prioritize su
A Digital Object Identifier (DOI) is a unique, persistent alphanumeric code that identifies a scholarly work (journal article, book chapter, dataset, preprint) and persists even if the URL changes. Introduced in 1998 by Norman Paskin and the International DOI Foundation, DOIs are now standard in academic publishing. Th
The Directory of Open Access Journals (DOAJ) is a community-maintained, freely accessible directory of high-quality, peer-reviewed open-access journals and articles established in 2003.

Submitting a research protocol to an ethics committee (IRB, REC, or equivalent) is a mandatory procedural gateway in human subjects research. The application process requires researchers to document their study design, justify scientific rationale, disclose risks and benefits, provide participant protections (informed
Field-mapping meta-ethnography combines the breadth of a field-mapping (scoping) review with the interpretive synthesis power of meta-ethnography. It first maps the full landscape of qualitative studies on a topic to understand what has been studied and how, then applies Noblit and Hare's seven-step meta-ethnographic s
Field-mapping scientometric analysis uses quantitative bibliometric techniques — co-citation, bibliographic coupling, co-authorship, and keyword co-occurrence — to delineate the intellectual structure and boundaries of a scientific field. By transforming large publication datasets into similarity networks and clusterin
Tables and figures are the primary means of presenting research data in scientific manuscripts. A well-designed table or figure enables readers to grasp complex data patterns instantly; a poorly designed one obscures findings or misleads. The ICMJE Recommendations and APA Publication Manual establish standards for tabl
Grey literature comprises documents and data not published through conventional commercial channels—including theses, government reports, clinical trial registries, conference abstracts, organizational policy documents, and working papers. Unlike journal articles, grey literature is not indexed in MEDLINE or Scopus and
The h-index, or Hirsch index, is a quantitative metric proposed by physicist Jorge Hirsch in 2005 to measure researcher productivity and citation impact simultaneously. A researcher has an h-index of h if they have published at least h papers, each cited at least h times. For example, an h-index of 20 means the researc
