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, 4.13% of publications had an unrecognized affiliation. Out of the publications with recognized affiliations, 37.93% were posted by at least one author from the top 10 institutions publishing in the journal. Another 5.17% included authors affiliated with research institutions from the top 11-20 affiliations. Institutions from the 21-50 range included 12.50% of all publications and 44.40% 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.

Best Nurse Practitioner Programs Influence on Medical Research

Influential medical research often starts with a solid educational foundation. Notably, the contributions from Journal of Internal Medicine highlights the crucial role of well-educated healthcare professionals, including nurse practitioners. Their expertise in arenas such as endocrinology, cardiology, and diabetes mellitus can be traced back to the rigorous academic training they receive. For example, many nurse practitioners assisting in these projects have pursued programs specifically designed to educate and train them on developing research that can provide cutting-edge developments in these fields. A notable example of this can be found in Montana where educational institutions provide some of the best nurse practitioner programs in the country. These programs offer rigorous coursework and ample research opportunities that equip nurse practitioners with the knowledge and skills necessary to contribute significantly to high-impact research projects in the medical field. Overall, the connection between high-quality nurse practitioner programs and impactful medical research reinforces the importance of a strong educational infrastructure in nurturing the professionals who generate significant advancements in health and medicine.
