Developing practical, reliable, and valid methods for monitoring athlete wellness and injury risk is an important goal for trainers, athletes, and coaches. Previous studies have shown that the countermovement vertical jump (CMJ) test is both a reliable and valid metric for evaluating an athlete's condition. This study examines the effectiveness of prescribed workouts on improving the quality of movement during CMJ. The data set consists of 2,425 pairs of CMJ scans for high school, college, and professional athletes training at a privately owned facility. During each scan, a force plate recorded 3 ground reaction force (GRF) measurements known to impact CMJ performance: eccentric rate of force development (ERFD), average vertical concentric force (AVCF), and concentric vertical impulse (CVI). After an initial scan, coaches either assigned the athlete a specific 1- or 2-strength movement plan (treatment group) or instructed the athlete to choose their own workouts (control group) before returning for a follow-up scan. A multivariate analysis of covariance (MANCOVA) revealed significant differences in changes to GRF measurements between athletes in the 2 groups after adjusting for the covariates sex, sport, time between scans, and rounds of workout completed. A principal component analysis of GRF measurements further identified 4 primary groups of athlete needs and the results provide recommendations for effective workout plans targeting each group. In particular, split squats increase CVI and decrease ERFD/AVCF; deadlifts increase AVCF and decrease CVI; alternating squats/split squats increase ERFD/CVI and decrease AVCF; and alternating squats/deadlifts increase ERFD/AVCF and decrease CVI.

This study explored the role of gender identity and stigma among trans* individuals in their pursuit of healthcare support. Through in-depth, qualitative interviews with 17 trans* individuals, we observed intersections of individual, interpersonal, and institutional modes of stigma across a variety of contexts of trans* healthcare. In our findings, we examine three specific themes related to trans* individuals anxiety about seeking healthcare support—tough decisions, fear, and benevolent oppression—as well as potential directions for future improvement in trans* healthcare. Our findings reveal that trans* individuals apprehension about seeking healthcare support stems from a "big picture" account of trans* healthcare, wherein their own individual experiences are situated against the larger backdrop of anti-trans* discrimination, both inside and outside the context of healthcare. These findings illuminate the intersectional workings of stigma and their inhibiting role on trans* healthcare support seeking. Findings are interpreted in light of participant suggestions for more inclusive trans* healthcare practices and potential steps to address noted inequities in trans* healthcare support provision.

Drug-substance uniformity is an important consideration for the final step in the manufacture of an active pharmaceutical ingredient. Uniformity studies are necessary to ensure that the entire contents of the batch are homogenous and that the drug substance specification sample is representative of the batch. This paper describes considerations for drug- substance uniformity, such as selection of appropriate test parameters and sample points, and approaches to establishing acceptance criteria. Additionally, operational considerations and best practices to ensure robust and consistent drug substance filtration and uniformity are described. [ABSTRACT FROM AUTHOR]

The article discusses the project of the National Center for Experiments in Television (NCET) which showcases potential forms of video art. Hal Foster describes an archival artist as someone who handles and produces archives in a manner that highlights the nature of all archival materials as constructed, fictive, and private. The NCET project recorded past experiments with particular apparatuses such as James Lastra's observations on technological developments in early sound recording and Stephen Beck's Beck Direct Video Synthesizer.
