Education policy increasingly promotes action groups as a key strategy for student and/or staff participation in school improvement and whole-school health promotion. Such groups can coordinate multi-component interventions, increase participation and engagement, and enable local adaptations, but few process evaluations have assessed this. We evaluated fidelity, feasibility and acceptability of action groups as part of a trial of a whole-school intervention to reduce bullying and aggression and promote health in English secondary schools, which reported multiple health and educational impacts. Action groups involved students and staff, supported by external facilitators, and drew on data on student needs. They aimed to: coordinate implementation of restorative practices and a social and emotional competencies curriculum; review policies and rules; and enact local decisions to modify school environments. Our process evaluation used interviews, focus groups, observations and questionnaires to assess action groups’ fidelity, role in coordination, role in local adaptation, support from external facilitators and data on student needs, and acceptability in engaging members. Fidelity was high in the first two years but lower in the third year when external facilitators withdrew. Student needs data were perceived as useful, but views on external facilitators were mixed. Groups successfully reviewed policies and rules, planned activities and coordinated restorative practices, but were less successful in implementing the curriculum. Success was facilitated by the involvement of school leaders. Members reported high satisfaction and empowerment. Action groups are a promising strategy for leading whole-school health promotion. Implementation is supported by external facilitation, local data and involvement of senior managers.  相似文献

The authors replicated a study (White, 1979) in which high correlations were obtained among the Wechsler Intelligence Scale for Children-Revised (WISC-R), the Peabody Individual Achievement Test (PIAT), and the Goodenough-Harris Draw-A-Man (DAM), and conclusions were drawn that all these instruments might not be necessary in the same test battery. The present study involved a larger sample (360 children). Much lower correlations among the instruments were obtained, although the pattern of correlation was similar. It was concluded that results of the White study may have overestimated the relationships between the variables because of factors unique to the sample. Test specificity appeared using the larger, normally distributed sample, suggesting a legitimate use of all three tests in a single battery.  相似文献

While dance was a common element of international diplomacy activities around the world during the 1950s and early 1960s, scholars have only recently begun to focus attention on this topic, especially as it concerns relationships forged beyond those of the Cold War superpowers. Using previously unexamined historical materials such as rare photographs and performance programs, dancer biographies, autobiographies and personal interviews, unpublished institutional histories, and contemporary periodicals, this article demonstrates not only that dance was an integral part of China’s inter-Asian cultural exchange between 1953 and 1962, but also that the PRC developed a distinct approach to dance diplomacy. Through a series of exchanges with India, Indonesia and Burma, China’s foreign ministers and dancers developed and refined a method of dance diplomacy in which the primary goal was to learn from, rather than export to, these neighboring countries. This approach harnessed the affective power of embodied aesthetic culture to literally “perform” Bandung ideals, namely, cooperation and mutual respect among Asian nations and an anti-imperialist cultural stance. Through the establishment in 1962 of the Oriental Song and Dance Ensemble, the PRC institutionalized this model of dance diplomacy, expanding it to include the entire Third World. Bandung-era dance diplomacy initiatives of the 1950s and early 1960s not only supported important new international alliances and political movements, but also asserted China’s self-identity as part of the East in the way that challenged Eurocentric ideals previously entrenched in China’s domestic dance field.  相似文献

This paper investigates the attributes of Corporate Social Responsibility (CSR) programmes in sport and their potential for sustainable community development. The gap between sport-related CSR and community development needs to be filled by shifting attention to the capacity building of communities. While the neoliberal foundations of CSR are recognized, it is essential to understand the ideological varieties driving CSR that can enable inclusiveness and collaboration in fostering community benefits of CSR programmes. The paper contributes to the literature on CSR in sport advancing the discourse, and sets the stage for a community-based framework for research: (1) related to sport as a tool for social change; (2) exploring the relationship of organizational motives, stakeholder engagement and CSR programme design/implementation; and (3) evaluating the perceived benefits of CSR programmes, and the extent to which these can help achieve sustainable community development.  相似文献

Multistage, ultra-endurance events in hot, humid conditions necessitate thermal adaptation, often achieved through short term heat acclimation (STHA), to improve performance by reducing thermoregulatory strain and perceptions of heat stress. This study investigated the physiological, perceptual and immunological responses to STHA prior to the Marathon des Sables. Eight athletes (age 42 ± 4 years and body mass 81.9 ± 15.0 kg) completed 4 days of controlled hyperthermia STHA (60 min·day?1, 45°C and 30% relative humidity). Pre, during and post sessions, physiological and perceptual measures were recorded. Immunological measures were recorded pre-post sessions 1 and 4. STHA improved thermal comfort (P = 0.02), sensation (P = 0.03) and perceived exertion (P = 0.04). A dissociated relationship between perceptual fatigue and Tre was evident after STHA, with reductions in perceived Physical (P = 0.04) and General (P = 0.04) fatigue. Exercising Tre and HR did not change (P > 0.05) however, sweat rate increased 14% (P = 0.02). No changes were found in white blood cell counts or content (P > 0.05). Four days of STHA facilitates effective perceptual adaptations, without compromising immune status prior to an ultra-endurance race in heat stress. A greater physiological strain is required to confer optimal physiological adaptations.  相似文献

Background:Game-based learning is a successful strategy for teaching various concepts to students, from general orientations to more in-depth material. Pharmacy students in a first-year lab course were introduced to library and drug information resources through a lecture-style class in their first week of school, which was ineffective in terms of engagement. To combat this issue, the pharmacy liaison librarian advocated for moving this class session later in the semester and proposed a game-based activity to replace the lecture.Case Presentation:“The Amazing Race: Drug Information Edition” was inspired by a well-known TV competition that involves completing several stages (called “legs”) of challenges to finish the race. The librarian developed questions designed to make students use various parts of the library website as well as two drug information databases. Students competed in teams, and the first three teams to complete the race were awarded small prizes. The race was first implemented in 2018, and modifications were made to the 2019 iteration based on student feedback.Conclusions:Despite several challenges, the race was well received by both the students and the course instructors and increased engagement with introductory library and drug information material. The activity has enhanced the librarian''s relationship and collaboration with the course faculty and made a positive impression on the students.  相似文献

This research examined varying levels of physical activity and psychomotor and physiological function in variously active older men. Very active moderately active, and low active participants were tested on simple (SRT) and choice reaction time (CRT), coincidence-anticipation timing (CAT), and VO2max. No significant differences for age or height were found, although percentage of fat, and weight were statistically different. Active groups were leaner and lighter. VO2max was significantly different between groups, as physically active groups yielded geater values. SRT and CAT also yielded significantly different results with more active participants showing better performance. No between-groups significant differences resulted for CRT. Generally, increased levels of physical activity were related to superior physiological outcomes and improved psychomotor peformance.  相似文献

Amplification of multiple unique genetic targets using the polymerase chain reaction (PCR) is commonly required in molecular biology laboratories. Such reactions are typically performed either serially or by multiplex PCR. Serial reactions are time consuming, and multiplex PCR, while powerful and widely used, can be prone to amplification bias, PCR drift, and primer-primer interactions. We present a new thermocycling method, termed thermal multiplexing, in which a single heat source is uniformly distributed and selectively modulated for independent temperature control of an array of PCR reactions. Thermal multiplexing allows amplification of multiple targets simultaneously—each reaction segregated and performed at optimal conditions. We demonstrate the method using a microfluidic system consisting of an infrared laser thermocycler, a polymer microchip featuring 1 μl, oil-encapsulated reactions, and closed-loop pulse-width modulation control. Heat transfer modeling is used to characterize thermal performance limitations of the system. We validate the model and perform two reactions simultaneously with widely varying annealing temperatures (48 °C and 68 °C), demonstrating excellent amplification. In addition, to demonstrate microfluidic infrared PCR using clinical specimens, we successfully amplified and detected both influenza A and B from human nasopharyngeal swabs. Thermal multiplexing is scalable and applicable to challenges such as pathogen detection where patients presenting non-specific symptoms need to be efficiently screened across a viral or bacterial panel.  相似文献
