The research reported in this paper investigates why teachers in regional primary schools in the Ballarat region of Victoria, Australia, are choosing to outsource the teaching of sexuality education. A survey was conducted of 29 Year 5 and Year 6 teachers from local primary schools. The teachers provided information about: their confidence in delivering sexuality-related topics; their perceptions of the relevance of given sexuality topics to their students; the teachers' own professional development preferences; and what they saw as their personal limitations in teaching sexuality education. Teachers tended to report low confidence in teaching topics that are considered ‘sensitive’, such as menstruation, wet dreams and sexual intercourse. Furthermore, they indicated a need for professional development in teaching sexuality education. The greatest hurdle identified lies in identifying how to motivate, engage and support teachers to take a professional interest in teaching sexuality education.  相似文献

Changing trends in library use and management of e-resources were discussed by Jane Burke from ProQuest/Serials Solutions. A paradigm shift in library collections has occurred in which e‐resources are now the major component of new library materials, requiring new ways to manage and display them. The use of e‐resource access and management services was discussed as a helpful tool, along with federated searching. Burke suggested that by spending less time processing print materials and ending bibliographic instruction, more time will be available for librarians to market and manage e-resources, which will be of greater benefit to today's library users.  相似文献

Random samples of U.S. public libraries were surveyed in summer 2010 to ascertain their name authority cataloging practices. Comparisons of authority work processes and types of authority work done were made among public libraries of different sizes. Results were compared to previous studies of public and academic libraries.  相似文献

More than 5,000 households with a person identified as having a physical, mental, or emotional condition that impairs participation in activities were surveyed about their opinions concerning barriers to public library use and opinions about efforts by public libraries to be useful to people with disabilities. Results showed that perceptions of accessibility, collections, and presence of assistive or adaptive devices for people with disabilities were slightly more positive if someone in the household had used the public library in the past year. Data used for the study were from the October 2002 Current Population Survey, a federal survey conducted by the U.S. Census Bureau for the Bureau of Labor Statistics.  相似文献

The 2011 Hearst Philippine Biodiversity Expedition was the largest ever launched by the California Academy of Sciences, and was also the largest and most diverse expedition to ever take place in the Philippines. Filipino collaboration and participation were vitally important from the outset. Scientists of both nations documented biodiversity in a variety of habitats and across multiple biological disciplines, identifying more than 500 species new to science. The expedition also modeled a new way of embedding substantial educational outreach and media coverage, and promoting conservation actions. More than 900 people attended educational events in the Philippines. Extensive television, radio, online, and print media coverage occurred both in the Philippines and in the U.S. during the expedition and after. A conference at the end shared preliminary results among scientists, educators, policy makers, and media, before the Academy team even left the country.  相似文献

Sweat lactate reflects eccrine gland metabolism. However, the metabolic tendencies of eccrine glands in a hot versus thermoneutral environment are not well understood. Sixteen male volunteers completed a maximal cycling trial and two 60-min cycling trials [30°C?=?30±1°C and 18°C?=?18±1°C wet bulb globe temperature (WBGT)]. The participants were requested to maintain a cadence of 60 rev?·?min?1 with the intensity individualized at ~ 90% of the ventilatory threshold. Sweat samples at 10, 20, 30, 40, 50 and 60?min were analysed for lactate concentration. Sweat rate at 30°C (1380±325?ml?·?h?1) was significantly greater (P<0.05) than at 18°C (632±311?ml?·?h?1). Sweat lactate concentration was significantly greater (P<0.05) at each time point during the 18°C trial, with values between trials tending to converge across time. During the 30°C trial, both heart rate (20, 30, 40, 50 and 60?min) and rectal temperature (30, 40, 50 and 60?min) were significantly higher than in the 18°C trial. Higher sweat lactate concentrations coupled with lower sweat rates may indicate a greater relative contribution of oxygen-independent metabolism within eccrine glands during exercise at 18°C. Decreases in sweat lactate concentration across time suggest either greater dilution due to greater sweat volume or increased reliance on aerobic metabolism within eccrine glands. The convergence of lactate concentrations between trials may indicate that time-dependent modifications in sweat gland metabolism occur at different rates contingent partially on environmental conditions.  相似文献

The aims of this study were to determine the influence of an 8-over spell on cricket fast bowling technique and performance (speed and accuracy), and to establish the relationship of selected physical capacities with technique and performance during an 8-over spell. Fourteen first-grade fast bowlers with a mean age of 23 years participated in the study. Physical capacities assessed were abdominal strength, trunk stability, selected girth and skinfold measures. During the delivery stride, bowlers were filmed from an overhead and lateral perspective (50 Hz) to obtain two-dimensional data for transverse plane shoulder alignment and sagittal plane knee joint angle respectively. Ball speed was measured by a radar gun and accuracy by the impact point of each delivery on a zoned scoring target at the batter's stumps. Shoulder counter-rotation did not change significantly between overs 2 and 8 for all bowlers, but was significantly related to a more front-on shoulder orientation at back foot impact. When the front-on fast bowlers ( n = 5) were isolated for analysis, shoulder counter-rotation increased significantly between overs 2 and 8. Ball speed remained constant while accuracy showed some non-significant variation during the spell. Shoulder counter-rotation was significantly related to accuracy scores during the second half of the 8-over spell. Chest girth and composition and body composition were significantly related to ball release speed at various times during the spell.  相似文献

Districts across the country are currently adopting models of professional learning communities (PLCs) as a means for improving teachers' instructional practice and student achievement. This evaluation research case study shares the 3-year history, development, and challenges of a district-wide implementation of Critical Friends Groups (CFGs), a particular format for PLCs. Using Argyris and Schön's (1974) theories of action framework, the authors identify teachers' espoused theories about a contextually situated CFG initiative and examine teachers' conceptualizations about the ways in which their work influences the progression and effectiveness of this professional development model. Findings from this study suggest that the degree to which the CFG implementation model is integrated with other school improvement initiatives, specifically those that address teachers' professional development, dramatically influences how key stakeholders conceptualize and draw the necessary connections to their roles in improving instructional practice and addressing student achievement and learning.  相似文献
