Prior research on pretrial publicity has produced mixed results and a roughly equal number of studies show an effect, show no effect, or show mixed results. We explored the effects of (a) homogenous vs. heterogeneous exposure (whether deliberating jurors were all exposed to the same publicity or not) and (b) pre-deliberation queries as potential contributors to mixed results. We found an effect for positive but not negative publicity on conviction rates but not evidence ratings. Exposure heterogeneity appears to explain these differences and pre-deliberation queries did appear to play some role in the obtained outcomes. Overall these findings do not replicate a robust publicity effect and future research should consider how homogeneous exposure and pre-deliberation opinion queries influence results. 相似文献

This article reports on teachers' reactions to a pilot implementation of a new standards-based teacher evaluation system in a medium-sized Midwestern school district. The system, based on the Framework for Teaching (Danielson, 1996), was intended to serve as the foundation for a new knowledge and skill pay plan for teachers. Teacher reactions were measured using both interview and survey methods. Teachers' overall favorableness toward the system, as measured by the survey, was correlated with acceptance of the teaching standards, perception of the evaluation process as fair and the evaluator as capable and objective, and perception that the evaluation system had a positive impact on their teaching. In interviews, teachers perceived both positive and negative aspects of the system, and for many these more or less balanced each other. While most teachers accepted the evaluation standards and the need for an evaluation system, many also perceived that the system added too much to teachers' workloads and did not provide enough feedback. Based on these results several changes were made in the evaluation system prior to full implementation. The results are discussed with reference to previous research and the Personnel Evaluation Standards. 相似文献

While the role of leadership in improving schools is attracting more worldwide attention, there is a need for more research investigating leaders’ experiences in different national contexts. Using focus-group and semi-structured interview data, this paper explores the background, identities and experiences of a small group of Jamaican school leaders who were involved in a leadership development programme. By drawing on the concepts of culture, socialisation and identity, the paper examines how the participants’ journeys of becoming and being school leaders are influenced by national-level societal and cultural issues, experienced at a local level. The findings suggest that in becoming school leaders, the participants perceived that they had a strong sense of agency in attempting to change the social structures within the institutions they lead and in the surrounding local communities, which in turn, they hope, will have a lasting effect on the nation as a whole. 相似文献

This study examined the effects of rewards on the ideational fluency of 75 preschool children. Assigned to a reward or nonreward condition, the children were administered two ideational fluency tasks, Unusual Uses and Pattern Meanings. Analyses revealed a significant main effect for reward on the ideational fluency components of originality, total fluency, and flexibility. In all cases the rewarded subjects scored lower than the nonrewarded group. These findings support the growing body of evidence that rewards are detrimental to creative functioning. 相似文献
