Status and Trends of Physical Activity Surveillance, Policy, and Research in 164 Countries: Findings From the Global Observatory for Physical Activity—GoPA! 2015 and 2020 Surveys

Background: Physical activity (PA) surveillance, policy, and research efforts need to be periodically appraised to gain insight into national and global capacities for PA promotion. The aim of this paper was to assess the status and trends in PA surveillance, policy, and research in 164 countries. Methods: We used data from the Global Observatory for Physical Activity (GoPA!) 2015 and 2020 surveys. Comprehensive searches were performed for each country to determine the level of development of their PA surveillance, policy, and research, and the findings were verified by the GoPA! Country Contacts. Trends were analyzed based on the data available for both survey years. Results: The global 5-year progress in all 3 indicators was modest, with most countries either improving or staying at the same level. PA surveillance, policy, and research improved or remained at a high level in 48.1%, 40.6%, and 42.1% of the countries, respectively. PA surveillance, policy, and research scores decreased or remained at a low level in 8.3%, 15.8%, and 28.6% of the countries, respectively. The highest capacity for PA promotion was found in Europe, the lowest in Africa and low- and lower-middle-income countries. Although a large percentage of the world’s population benefit from at least some PA policy, surveillance, and research efforts in their countries, 49.6 million people are without PA surveillance, 629.4 million people are without PA policy, and 108.7 million live in countries without any PA research output. A total of 6.3 billion people or 88.2% of the world’s population live in countries where PA promotion capacity should be significantly improved. Conclusion: Despite PA is essential for health, there are large inequalities between countries and world regions in their capacity to promote PA. Coordinated efforts are needed to reduce the inequalities and improve the global capacity for PA promotion

Impact of Pre-Advanced Pharmacy Practice Experience (APPE) Curriculum on Student Pharmacists\u27 Professional Identity Formation.

OBJECTIVE: To (1) evaluate changes in student pharmacists\u27 professional identity during a curriculum prior to advanced pharmacy practice experiences (APPEs) and (2) describe the components of a pre-APPE curriculum that positively and negatively influenced students\u27 professional identity formation (PIF). METHODS: The University of Washington School of Pharmacy launched a new curriculum in 2019 featuring components intentionally designed to support students\u27 PIF. The Macleod-Clark Professional Identity Scale (MCPIS) was administered to the class of 2023 before starting pharmacy school (pre) and upon completion of the pre-APPE curriculum (post). The postsurvey also contained 2 open-response questions asking students to identify the most positive and negative influences on their PIF. Mean pre- and post-responses were calculated for all MCPIS items and each MCPIS item and compared using paired t tests. Responses to the open-ended questions were sorted into categories using inductive thematic analysis and frequencies were calculated. RESULTS: A total of 99 students (96%) completed both surveys. Mean MCPIS pre-scores and post-scores were both 3.3, indicating no statistically significant change in professional identity. The most frequently reported positive influences on PIF were didactic coursework (40%), experiential learning (30%), and student organizations (27%). The most frequently reported negative influences were didactic coursework (27%), none (25%), and perceptions of the pharmacy profession (22%). CONCLUSION: Students\u27 overall professional identity, as measured by the MCPIS, did not change during the pre-APPE curriculum. Didactic coursework had the most common positive and negative influence on professional identity prior to APPEs

X-ray birefringence: a new strategy for determining molecular orientation in materials

While the phenomenon of birefringence is well-established in the case of visible radiation and is exploited in many fields (e.g., through the use of the polarizing optical microscope), the analogous phenomenon for X-rays has been a virtually neglected topic. Here, we demonstrate the scope and potential for exploiting X-ray birefringence to determine the orientational properties of specific types of bonds in solids. Specifically, orientational characteristics of C–Br bonds in the bromocyclohexane/thiourea inclusion compound are elucidated from X-ray birefringence measurements at energies close to the bromine K-edge, revealing inter alia the changes in the orientational distribution of the C–Br bonds associated with a low-temperature order–disorder phase transition. From fitting a theoretical model to the experimental data, reliable quantitative information on the orientational properties of the C–Br bonds is determined. The experimental strategy reported here represents the basis of a new approach for gaining insights into the orientational properties of molecules in anisotropic materials
