Bibliometric studies are important to understand changes and improvement opportunities in academia. This study compared bibliometric trends for two major sports medicine/arthroscopy journals, the American Journal of Sports Medicine® (AJSM®) and Arthroscopy® over the past 30 years. Trends over time and comparisons between both journals were noted for common bibliometric variables (number of authors, references, pages, citations, and corresponding author position) as well as author gender and continental origin. Appropriate statistical analyses were performed. A p < 0.001 was considered statistically significant. One representative year per decade was used. There were 814 manuscripts from AJSM® and 650 from Arthroscopy®. For AJSM® the number of manuscripts steadily increased from 86 in 1986 to 350 in 2016; for Arthroscopy® the number of manuscripts increased from 73 in 1985/1986, to 267 in 2006, but then dropped to 229 in 2016. There were significant increases in all bibliometric variables, except for the number of citations which decreased in Arthroscopy®. There were significant differences in manuscript region of origin by journal (p ¼ 0.000002). Arthroscopy® had a greater percentage of manuscripts from Asia than AJSM® (19.3% vs 11.5%) while AJSM® had a greater percentage from North America (70.3% vs 59.2%); both journals had similar percentages from Europe (18.2% for AJSM® and 21.6% for Arthroscopy®). For AJSM® the average percentage of female first authors was 13.3%, increasing from 4.7% in 1986 to 19.3% in 2016; the average percentage of female corresponding authors was 7.3%. For Arthroscopy®, the average percentage of female first authors was 8.1%, increasing from 2.8% in 1985/1986 to 15.7% in 2016 (p ¼ 0.00007). In conclusion, AJSM® and Arthroscopy® showed an increase in most variables analyzed. Although Arthroscopy® is climbing at a higher rate than AJSM® for female authors, AJSM® has an overall greater percentage of female authors.

Key Takeaways For utilities, digital twins are the next step in their digital transformation. Digital twins have various functional purposes and levels of maturity. Digital twins can be used to transfer knowledge from a retiring workforce, support increased customer trust and satisfaction, and optimize operations.

The first, and still the chief, object of the Red Cross is to mitigate the suffering caused by war.Man, from earliest time, has sought to prevent war if possible, and to mitigate its consequences when it does occur. By the “Truce of God” first recorded in 1027, fighting, then recognised as the occupation of a gentleman, was forbidden under ecclesiastical sanctions, from Thursday morning to Sunday night. This is an approach to the outlawing of war. Still older, dating from the Council of Charroux in 980, was the “Peace of God” which declared inviolable during war, the persons of peasants, merchants, and pilgrims and especially of priests, monks and nuns—on whose care the wounded and sick depended at that time.
