This article reports on a study that was funded by the National College for School Leadership in order to explore practices, drivers and barriers to leadership talent identification, leadership development, leadership succession planning and leadership retention within a group of contextually different schools. The article offers two narratives from primary school headteachers, operating in different circumstances, in order to show the ways in which schools are attempting to ‘grow their own’ leaders through systematic policies for leadership development. Key features of successful schools which consider themselves to be good at leadership development, which may be relevant to other primary schools, are outlined. 相似文献

Abstract A telemedicine project was conducted to explore the delivery of childbirth preparation classes originating at a large regional hospital to a remote site at a small rural hospital. Over six months, three series of classes were included in the project, with twenty‐four participants at the originating site and twenty participants at the remote site. A two‐way, audio/video teleconferencing system with multiple cameras and monitors was employed for instruction. A registered nurse taught the class and a site facilitator assisted at the remote site. Evaluation of the project was done through surveys, interviews, and observations. The classes were well received by project participants at both sites. Principal advantages cited were increased availability of the programs, improved attendance, and convenience to rural participants. The principal disadvantages cited focused on technical problems, particularly audio quality. 相似文献

Two studies ( N = 456) compared the development of concepts of animal species and human gender, using a switched-at-birth reasoning task. Younger children (5- and 6-year-olds) treated animal species and human gender as equivalent; they made similar levels of category-based inferences and endorsed similar explanations for development in these 2 domains. In contrast, 10-year-olds and adults treated gender and species concepts as distinct from one another. They viewed gender-linked behavioral properties as open to environmental influence and endorsed environment-based mechanisms to explain gender development. At all ages, children demonstrated differentiated reasoning about physical and behavioral properties, although this differentiation became more stable with age. The role of psychological essentialism in guiding conceptual development is discussed. 相似文献

The conventional definition of quality factor Q in terms of time-average stored energy is widely assumed to be a measure of the input bandwidth of any ordinary electromagnetic system. But the extent to which this assumption is true has never been established. In the case of all radiating systems, for example, it is known to fail completely. It can be made true quite generally, however, by including only those parts of the total time-average stored energy that give a physically observable contribution to the input bandwidth. Explicit formulas for these newly defined observable stored energies are developed that are valid for any electromagnetic system that is linear, passive, and time-invariant. 相似文献

This study examines risk and protective factors associated with on-time grade attainment among a cohort of high risk elementary age youth 3?years post truancy intervention. Conjunctive Analysis of Case Configurations was used to identify dominant subpopulation profiles and assess distinctions in the likelihood of on-time grade completion among groups with unique combinations of characteristics. Comparisons of subpopulation profiles revealed substantial contextual variability in the influence of race, gender, service completion, psychosocial risk factors, and truancy. Findings indicate race is not influential across all grades but appears to be dependent on truancy level. Although psychosocial risk factors are not present for K-3rd profiles, they are critical among 4-5th graders, specifically lack of motivation. Findings from this study allow practitioners to better understand risk and protective factors influencing grade progression and aids in the development of individualized case management and intervention. Findings indicate better policies are needed to address early truancy. 相似文献

Effect of team rank and player classification on activity profiles of elite wheelchair rugby players
The aim of the current study was to establish which indicators of mobility are associated with successful wheelchair rugby performance and determine whether these indicators differed across classification. Data were collected from 11 international teams during 30 matches (353 match observations) using a radio-frequency-based, indoor tracking system across two tournaments. Players (n = 111) were first grouped by team rank as determined by their International Wheelchair Rugby Federation (IWRF) world ranking (LOW, MID, HIGH) and then into one of four groups based on their IWRF classification: Group I (0.5), Group II (1.0–1.5), Group III (2.0–2.5) and Group IV (3.0–3.5). The volume of activity (relative distance and mean speed), peak speed and time spent within classification-specific arbitrary speed zones were calculated for each individual. Although no differences were identified in the volume of activity, playing time was significantly reduced in LOW (34:51 ± 8:35) compared to MID (48:54 ± 0:51) and HIGH (45:38 ± 9:53), which was further supported by the greater number of substitutions performed by LOW. HIGH achieved greater peak speeds (3.55 ± 0.40 m · sˉ1) than LOW (3.27 ± 0.42 m · sˉ1) and MID (3.45 ± 0.41 m · sˉ1). Peak speed was further shown to be classification-dependent (P ≤ 0.005), whereby HIGH Groups III and IV players achieved greater peak speeds than LOW and MID. The time spent performing high-intensity activities was also greater in HIGH compared to LOW and MID, whilst further influenced by classification (P ≤ 0.0005). To conclude, peak speed and the ability to perform a greater number of high-intensity activities were associated with successful performance in wheelchair rugby. 相似文献

Purpose: Parents play an important role in supporting children’s physical activity (PA) behavior. Parent PA support is a behavior unto itself that has been examined within the framework of an adapted theory of planned behavior (TPB). The primary purpose of this research was to identify key barriers to parent PA support to understand perceptions of control in relation to parent PA support. The second purpose of this research was to identify potential strategies to enhance parent PA support via enhanced perceived behavioral control. Method: Focus groups were conducted with parents (N = 21) of children aged 5 to 11 years old. A deductive content analysis was employed to analyze the data guided by an adapted TPB. Results: Themes related to barriers included parents’ motivation, affective experiences in providing PA support, and control factors (e.g., cost, time, safety concerns, screen). Themes related to potential strategies included opportunities for participation and improved affective experiences for parents, community parenting, and self-regulatory strategies. Conclusion: The identification of specific barriers to parent PA support can guide the development of interventions to facilitate parent PA support. Informational, programming, and self-regulatory training interventions may be useful in enhancing parent support. 相似文献

The aim of this research is to explore whether participation in study abroad by community college students impacts levels of engagement and if there is a connection between studying abroad and academic achievement. While university-level studies have a history in exploring these questions, the same is not true for community colleges. The California Community College Student Outcomes Abroad Research project (CCC SOAR) uses a mixed methods design to examine data that evidences how participation in study abroad programs not only has implications for personal development and global learning, but also has a range of indicators of academic success variables. Data show that there is a range of positive outcomes that occur as a result of studying abroad for all students across an array of early, midstream, and terminal outcomes due to engagement-enhancing components such as shared common experiences, nurturing behavior from faculty, and increased student interaction in collaborative activities. 相似文献
