The increasing use of cyberspace as a social networking forum creates a new medium for youth to become victims of peer aggression. This study used factor analysis techniques to confirm whether survey questions about frequency of cyber victimization formed a distinct latent construct from questions about relational and overt victimization information in a large (N = 1,665) sample of middle school students. A secondary goal was to relate experiences of cyber victimization to symptoms of depression and social anxiety. Results indicate that cyber victimization is separate latent factor from overt and relational victimization. Experiences of cyber victimization were weakly associated with symptoms of social anxiety, but not depression. These results signify that cyber victimization deserves future empirical and clinical attention. © 2009 Wiley Periodicals, Inc. 相似文献

Delayed conditional discriminations in which a sample indicates which comparison stimulus is correct have typically been used
in working memory research with animals. Following acquisition with no (0-sec) delay between the offset of the sample and
the onset of the comparison stimuli, delays of variable duration are introduced. The resulting retention functions are taken
as a measure of memory. We suggest that, in addition to memory loss due to the delay, the comparison of matching accuracy
at the 0-sec training delay with relatively novel test delays may produce a generalization decrement that varies as a function
of increasing delay. We tested this hypothesis by training pigeons with a mixed delay procedure from the start and found that
the retention functions for these pigeons were significantly shallower than those for a control group trained with 0-sec delays
and tested with longer delays, and, although reduced in magnitude, the differences persisted for as many as 15 sessions. We
propose that a measure of animals’ working memory can be obtained uninfluenced by a generalization decrement if they have
received comparable training with all of the delays that are tested. 相似文献

This paper features a case study of one US K-8 school district pioneering the use of “lesson study,” a teacher professional
development approach adapted from Japan. The case explores events that occurred in the district over more than 4 years (Spring
2000–Fall 2004) as lesson study spread nationally and within the district. We document four categories of changes that occurred
in the district’s lesson study approach, and describe some of the early consequences of these changes as well as conditions
that enabled the changes to occur. We argue that this case illustrates much of what we would hope to see in a maturing lesson
study effort, and conclude that other US sites may need to go through similar changes, organize similar supports, and persist
in their learning about lesson study to successfully adapt this model to their local contexts. 相似文献

Academics are increasingly required to balance the expectations of the ‘old’ academy with a future model of universities as interdisciplinary and transdisciplinary ‘problem solvers’. This paper highlights changing expectations of academics in producing alternative research outcomes in collaborative, practice‐based research. Through a series of workshops with 20 researchers, preferred research outcomes and tensions in achieving these outcomes were identified. The tensions identified are presented as three dichotomies comprising the tension between: (a) ‘I versus We’ ‐ individual versus team expectations & outcomes. (b) Disciplinary outcomes versus inter‐/transdisciplinary outcomes. (c) Learning versus research objectives for the students and academics involved. These tensions reflect the authors' experiences of working in three international sustainability projects, drawing on lessons learned from these projects, with recommendations for universities seeking to implement interdisciplinary and transdisciplinary doctoral and postdoctoral programmes. Recommendations include the need for formal and informal leadership models, strong communication skills, empathy and willingness to learn from each other. A need for more systemic changes within university administration to better reward and value the breadth and depth of collaborative work, while facilitating open learning cultures and practice‐oriented learning opportunities and curricula across faculties was also identified. 相似文献

To address gaps in the availability of validated measures that assess early childhood teachers' workplace experiences, the current study examined the validity of the Early Childhood Teacher Experiences Scale (ECTES) for use in a diverse Head Start program. Mean differences in the ECTES dimensions of self-efficacy, job stress, and school support were examined across teachers' demographic characteristics and observed teacher–child interaction quality. Multilevel models examined associations between ECTES dimension scores and children's social-emotional and academic skills (N = 161 preschool teachers and N = 3,152 children). Findings support the reliability and validity of the three-factor structure of the ECTES in the diverse Head Start teacher sample. Higher teacher-reported self-efficacy and school support were associated with higher observed classroom emotional support, instructional support, and classroom organization. Higher teacher-reported self-efficacy was associated with fewer years of teaching experience. With respect to child outcomes, higher teacher self-efficacy and school support were associated with lower behavior problems and higher social-emotional skills but were not associated with academic skills. Implications of the findings, limitations, and future directions are discussed. 相似文献

AbstractThis study introduces the scope and nature of teacher candidate (TC) supervision in an era of clinically-based teacher preparation. The findings emerged from a qualitative meta-analysis of 82 articles related to TC supervision published between 2001 and 2017. The study recognizes core supervision concepts drawn from decades of empirical literature yet moves the field substantially forward by identifying a framework that includes: (1) tasks, (2) high-leverage practices, and (3) pedagogical routines of supervisory practice. This framework defines a new understanding of how supervisors support TC learning throughout their clinical experiences. By naming the scope and nature of TC supervision, the framework of tasks, high-leverage practices, and pedagogical routines of supervisory practice can help supervisors become more conscious and more skilled about their practice to develop their professional vision of supervision. The framework can also guide the evaluation and re-design of TC supervision within clinically based teacher preparation. 相似文献
