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, 20.83% of publications had an unrecognized affiliation. Out of the publications with recognized affiliations, 16.07% were posted by at least one author from the top 10 institutions publishing in the journal. Another 6.74% included authors affiliated with research institutions from the top 11-20 affiliations. Institutions from the 21-50 range included 10.79% of all publications and 66.40% 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.

Exploring Connections to Educational Institutions

Another aspect to consider when analyzing the depth of research and academic papers provided in the journal is the connection of the authors to esteemed educational institutions. Such connections can add weight to the discussions presented in the journal and provide avenues for direct educational influence and knowledge transfer. For instance, in the field of medicine, specifically nursing, having contributors who are also active educators or professionals from recognized nursing schools can greatly enhance the journal's value. This allows the publication to offer perspectives that are not only theoretically sound, but are also grounded in actual practice and experience. An interesting parallel to draw would be evaluations of nursing school programs themselves, such as a comprehensive analysis of the best nursing schools in New Mexico. A study like this offers a direct look at the institutions that shape many of the professionals conducting significant research in the field of medical sciences, much like many of the contributors to our journal. These aspects can provide insightful context when understanding the backgrounds of the authors and their unique perspectives. However, it's worth mentioning that these insights are merely complementary to the objective assessments of the journal's research quality. Ultimately, the scholarly value of the publications comes from their scientific rigor, innovative input, and contribution to the field. By recognizing these connections, readers are better informed about the authorship ecosystem and can understand the potential influences that shape the discussions at play.
