This qualitative research was designed to evaluate the extent to which a national reform in Israeli child protection decision making committees was achieving its aim to strengthen professional judgment through introducing a new standard tools package into practice.Twenty-one case studies of families referred to the committee were investigated and followed up after six months. Data were collected through interviews with social workers, field observations of the committees’ discussions and document review. Using a systems approach as a conceptual framework, everyday practice was studied within its organizational context. A key finding of the research was a very limited utilization of the tools in practice. Evidence showed no advanced performance in the few cases where the tools were used, and that when they were used they mainly operated to record customary practice. Follow up data provided limited evidence of improvement in the safety and well-being of vulnerable children. The analysis revealed several systemic factors that interfered with the tools being fully and successfully implemented, including pressure of workloads, practitioners’ inadequate skills, limited professional support, and an organizational culture that discouraged sound practice. The research directs attention to the organizational changes needed in order to enhance the provision of effective help for children and families. 相似文献

This paper explores the concept ‘pedagogical cultural identity’ as one that embeds cultural knowledge and lived experience into pedagogical practice. Four narratives were constructed from fifteen in-depth interviews with early career Aboriginal teachers who completed their Aboriginal Studies teaching degree at the University of Sydney. The study found that these teachers enacted their habitus, harnessed their social and cultural capital, and mobilised their relationship building skills in the construction of their professional identity. Significantly, contextual power relations influenced the enactment of a pedagogical cultural identity, challenging assumptions of a presumed identity claim by exploring its potential and limitations. 相似文献

简要介绍了薄膜、单晶硅和多晶硅太阳能电池板的优缺点以及实现最大功率点跟踪的几种方法。结合温州地区的太阳辐射情况,利用扰动观察法测量了大量的数据,以比功率为衡量标准对三种太阳能电池板的实际发电能力进行了比较。结果表明,不管是在光强很强还是在光强较弱的环境下,单晶硅太阳能电池板的发电能力均最高;对另两种太阳能板,在光强较强时,薄膜太阳能电池板占优势,在光强很弱时,多晶硅太阳能电池板发电能力更强。 相似文献

PurposeLong-term training specificity is thought to alter performance in tests evaluating strength and power production capability. The aim of the present study was to provide additional information to the limited existing knowledge concerning the possible differences of the force/time profile of squat jumping among different groups of young female athletes.MethodsOne hundred and seventy-three adult women (20.1 ± 2.8 years, 1.71 ± 0.09 m, 65.6 ± 10.3 kg, mean ± SD for age, height, and mass, respectively) engaged in track and field (TF), volleyball (VO), handball (HA), basketball (BA), and physical education students (PE) executed maximal squat jumps (SQJ) on a force plate. Pearson's correlation was used to identify the relationship between SQJ performance, the anthropometric characteristics and the biomechanical parameters. Differences concerning the biomechanical parameters among groups were investigated with analysis of variance, while the force- (FPD) or time- (TPD) dependency of SQJ execution was examined using principal components analysis (PCA).ResultsSQJ was unrelated to body height but significantly correlated with body mass (r = −0.26, p = 0.001). TF jumped higher and produced larger peak body power output compared to all the other groups (p < 0.05). All athletes were superior to PE since they performed the SQJ with a longer (p < 0.05) vertical body center of mass trajectory during the propulsion phase. PCA results revealed that TF significantly differentiated than the other groups by relying on FPD.ConclusionVarious different profiles of FPD and TPD were detected due to different sporting background in young female athletes. Since TF superiority in SQJ was relied on the larger power production and a greater FPD, female indoor team sport athletes are suggested to execute jumping exercises adopting the jumping strategies utilized by TF. 相似文献
