Libraries must continually adapt to meet the ever-changing needs of users. Doing so requires the ability to be flexible and respond quickly. This is a case study of how The George Washington University Libraries rethought its approach to collection development using a cross-functional, team-based strategy that leveraged the benefits of Agile project management. Adopting an Agile approach to collection development maximized the impact of the library’s financial resources and enabled staff to develop new skills. This project underscores the value of collaboration, agility, and experimentation in libraries. 相似文献

Beyond some contracted minimum, salaried workers’ hours are largely chosen at the worker's discretion and should respond to the strength of contract incentives. Accordingly, we consider the response of teacher hours to accountability and school choice laws introduced in US public schools over the past two decades. Total weekly hours of full-time teachers have risen steadily since 1983 by about an hour, and after-school instructional hours have increased 34 percent since 1987. Average hours and the rate of increase also vary widely across states. However, after accounting for a common time trend in hours, we find no association between the introduction of accountability legislation and the change in teacher hours. Education reforms are, however, associated with an increase in student test scores, presumably due to other types of changes in school and teacher behavior. 相似文献

ABSTRACTThis study focuses on how young people read and discuss two political documentary films, Labor Day and Hillary: The Movie. We were specifically interested in the impact of the film viewing and discussion on participants’ beliefs about the issues in the films, how they view evidence and expertise in the films, and how the session impacted their views of documentaries as a source. Groups were designed according to composite political scores and individuals (n?=?30) were selected to form liberal, conservative, and two mixed groups (strong and moderate) for the viewing and discussion. Our analysis illustrates the power of political ideology in shaping how expertise is viewed and how evidence is warranted in film – and the role of social context and peer discussion in this process. Implications for media and democratic education in times of political polarization are discussed. 相似文献

We report on the construction and application on an instrument entitled the “Science Achievement Influences Survey” to assess combined effects of student attitudes about science, peer interaction, and home support, and the frequency of student‐centred and teacher‐centred instructional practices on student achievement. Controlling for pre‐test content knowledge, results indicated that student‐centred teaching practices have a positive association with student achievement (p < .01; i.e., group experiments) and a negative association with teacher‐centred teaching practices (p < .01; i.e., copying notes). Additionally, student attitudes about science were positively associated with student‐centred teaching practices (p < .01) and negatively associated with teacher‐centred teaching practices (p < .01). Most significantly, this study documents the predicted gains in science achievement associated with frequency of specific instructional practices used by middle‐school science teachers. Especially noteworthy and significant is the finding that near‐daily implementation of group experiments and reduction of extensive note‐copying during class yield the greatest positive impact on student achievement. Outside of school, peer interaction and home support were not significantly associated (p > .05) with student achievement. The student sample included 611 middle‐school science students with a wide range of socioeconomic and cultural backgrounds. 相似文献

This study explored how neighborhood characteristics may relate to African American adolescents' internalizing symptoms via adolescents' social support and perceptions of neighborhood cohesion. Participants included 571 urban, African American adolescents (52% female; M age = 17.8). A multilevel path analysis testing both direct and indirect effects of neighborhood characteristics on adolescents' mental health outcomes was conducted. Higher neighborhood poverty and unemployment rates predicted greater internalizing symptoms via lower cumulative social support and perceptions of neighborhood cohesion. In contrast, higher concentrations of African American and residentially stable residents in one's neighborhood related to fewer internalizing symptoms among adolescent residents via greater cumulative social support and perceptions of neighborhood cohesion. Implications of these findings are discussed. 相似文献

The purpose of this project was to describe the implementation of a perinatal health fair intended to connect local women to holistic resources. Researchers used participatory strategies to develop the health fair with local women and perinatal educators. Researchers evaluated the health fair using pragmatic measures based on the (Reach, Effectiveness, Adoption, Implementation, Maintenance) framework. Forty-two attendees were reached and 23 educators hosted booths and educational sessions. Feedback indicated strong enthusiasm for future similar events. Nearly three quarters of the time spent implementing the health fair was devoted to building relationships within the community. Overall, this project provides practical and empirical information to inform the planning, implementation, and evaluation of perinatal health fairs that establish meaningful connection between local women, perinatal educators, and health researchers. 相似文献

The purpose of this study was to examine the effects of short-term Rhodiola Rosea (Golden Root Extract (GRE)) supplementation on repeated Wingate performance. Eleven physically active college aged females were recruited for this study. In a within groups counterbalanced study design, participants were supplemented with either 1,500 mg/day of GRE or placebo (gluten-free cornstarch) for 3 days. Participants also took an additional 500 mg dose of corresponding treatment 30 minutes prior to testing of each trial. During each exercise trial, participants completed 3 × 15-second Wingate Anaerobic Tests (WAnTs) separated by 2-minute active recovery periods. Each exercise trial was separated by a 7 day washout period. Over the 3 × 15-second WAnTs, mean watts (p = 0.017, ES = 0.55), mean anaerobic capacity (p = 0.025, ES = 0.96), mean anaerobic power (p = 0.03, ES = 1.07), mean peak watts (p = 0.029,ES = 0.46), and mean total work (p = 0.017, ES = 0.49) were higher in the GRE treatment trial versus placebo. However, mean fatigue index (p = 0.094, ES = 0.39) was unaffected regardless of treatment. Our results show that GRE supplementation enhanced anaerobic exercise performance as measured through repeated WAnTs. GRE may possess ergogenic benefits and findings hold important implications for boosting anaerobic performance in repeated anaerobic bouts of exercise. 相似文献
