Objective: To review the physical activity promotion efforts of Power 5 conference institutions' summer transition programs. Methods: The websites of Power 5 Conference and affiliate member institutions (N = 78) were systematically reviewed and information on summer transition programs pertaining to health were extracted. Results: Most (n = 45, 57.7%) institutions had a summer transition program of some kind. Among those who had summer transition programs, 14 (31.1%) had a nonphysical activity health course (i.e. health and/or nutrition), while courses that incorporated a physical activity component were uncommon (n = 6, 13.3%). Only two institutions covered physical activity, nutrition, and health in at least one offered course. Conclusions: There is an opportunity for tertiary institution-level summer transitional programs to expand coverage to address a currently unmet need for physical activity promotion while avoiding perpetuation of existing inequities.

Objective: Disparities in physical activity (PA) and PA antecedents, such as exercise self-efficacy, based on the intersection of gender and race/ethnicity among college students are poorly understood. This study aimed to examine differences in PA and exercise self-efficacy based on the intersection of gender and race/ethnicity. Methods: An online survey collected data on demographics (age, gender, race/ethnicity), PA, and exercise self-efficacy from students (n = 5341) enrolled in general health and wellness at a large Northeastern U.S. University. Differences in PA and exercise self-efficacy based on gender and race/ethnicity were examined using two-way ANOVAs. Results: Analyses revealed significant differences in overall PA and exercise self-efficacy based on gender and race/ethnicity. A significant interaction between gender and race/ethnicity was found in relation to PA, but not exercise self-efficacy. Conclusion: Findings demonstrate the need for universities to tailor PA promotion efforts, and to consider how gender and race/ethnicity may intersect to influence PA participation.

Purpose: Regular participation in bicycling offers many health benefits. Universities throughout the U.S. have a large proportion of underrepresented populations among students/employees (e.g., racial/ethnic minorities, LGBTQ+, disabled) who participate in cycling at lower rates. The purpose of this study was to understand the current practices of universities for implementing equitable bicycling programming to their students/faculty/staff. Methods: A volunteer sample of U.S. university bicycle representatives (n = 19) were interviewed to analyze current practices, barriers, motivators, and future tools for equitable programming. Results: Multiple themes emerged from the interview, including barriers to programming such as lack of personnel and finances, as well as motivators such as partnering with off-campus organizations and connecting community/university infrastructures. Conclusions: Although various barriers exist for universities which may present decreased equitable programming, university bicycle/alternative transportation departments should consider partnering with on and off-campus organizations rooted into underrepresented populations to better provide equitable programming to these populations.

Abstract: Wendell Bell''s idealistic vision of the role of the sociologist in creating a brighter future for society and his theoretical framework of the role of intellectual elites in the decisions of nationhood are examined through the personal lens of a former Caribbean student of the West Indies Study Program at UCLA.

Cumulative osmotic stress models have been previously used to successfully describe the dehydration kinetics of recalcitrant seeds. For example, Liang and Sun demonstrated that a cumulative stress model effectively described the dehydration rate–dependence of recalcitrant seed viability under various drying conditions. In contrast, most studies describing the functionality of mammalian cells following drying conditions have been end-point oriented, describing cell viability as a function of the final moisture content reached or the duration of drying. This study applies a thermodynamics-based water metric similar to the Liang and Sun model to describe the viability of J774 mouse macrophage cells as a function of both moisture content and time of drying. Cells were incubated in full-complement DMEM media containing 50 mM trehalose, to enable trehalose loading by endocytosis. Treated cells and untreated controls that were not previously incubated in trehalose were dried in hypertonic (508 mOsm) and isotonic (308 mOsm) solutions of trehalose (200 mM) in phosphate-buffered saline (PBS). Various levels of dehydration were achieved by placing droplets of cell suspension in a desiccator for time periods up to 2 h. Cells were then immediately rehydrated and viability was assessed 45-min after rehydration. Cell viability was evaluated using a combination of Trypan Blue staining for membrane integrity of detached cells and Calcein AM – ethidium bromide fluorescence as a live-dead assay for attached cells. The cellular response was then evaluated as a function of cumulative osmotic stress, defined as the integral of the deviation in osmolality from isotonic conditions as a function of time. The results of this modeling suggested that significant cell injury was occurring in a moderate osmolality range, and that modulation of osmotic stresses in this range could lead to improved processing outcomes.
