Summary
The trend of increasing authors per article is also evident in occupational medicine journals. Higher impact factor occupational journals show a greater average number of authors per publication.
Area of Science:
- Medical Informatics
- Bibliometrics
- Occupational Medicine Research
Background:
- A growing trend of multiple authors per article is noted in general medical and health science journals.
- The extent of this trend in specialized medical fields, like occupational medicine, remains unclear.
Purpose of the Study:
- To investigate authorship trends in occupational medicine journals.
- To compare these trends with those in general medical and non-occupational medicine journals.
Main Methods:
- Analysis of single and multiple-authorship in occupational medicine journals from 1970-2007 using PubMed data.
- Calculation of average authors per article and percentage of single-author articles annually.
- Comparison of occupational medicine journal data with previously studied non-occupational medicine journals.
Main Results:
- A linear increase in average authors per article and a decrease in single-author articles were confirmed.
- The Journal of Occupational and Environmental Medicine showed a significantly steeper increase in author numbers compared to other occupational medicine journals.
- Occupational Medicine (Oxford) had a significantly higher percentage of single-author articles than other occupational medicine and major general journals.
Conclusions:
- The trend towards multiple authorship is consistent across medical specialty journals, including occupational medicine.
- Occupational medicine journals with higher impact factors correlate with a higher average number of authors per article.

01:33Pleiotropy
Pleiotropy is the phenomenon in which a single gene impacts multiple, seemingly unrelated phenotypic traits. For example, defects in the SOX10 gene cause Waardenburg Syndrome Type 4, or WS4, which can cause defects in pigmentation, hearing impairments, and an absence of intestinal contractions necessary for elimination. This diversity of phenotypes results from the expression pattern of SOX10 in early embryonic and fetal development. SOX10 is found in neural crest cells that form melanocytes,...
01:19X-linked Traits
In most mammalian species, females have two X sex chromosomes and males have an X and Y. As a result, mutations on the X chromosome in females may be masked by the presence of a normal allele on the second X. In contrast, a mutation on the X chromosome in males more often causes observable biological defects, as there is no normal X to compensate. Trait variations arising from mutations on the X chromosome are called “X-linked”.

02:18Cancer
Cancers arise due to mutations in genes involved in the regulation of cell division, which leads to unrestricted cell proliferation. Modern science and medicine have made great strides in the understanding and treatment of cancer, including eradicating cancer in some patients. However, there is still no cure for cancer. This is largely due to the fact that cancer is a large group of many diseases.
00:58Symbiosis
Symbiotic relationships are long-term, close interactions between individuals of different species that affect the distribution and abundance of those species. When a relationship is beneficial to both species, this is called mutualism. When the relationship is beneficial to one species but neither beneficial nor harmful to the other species, this is called commensalism. When one organism is harmed to benefit another, the relationship is known as parasitism. These types of relationships often...
