The cognitive functioning of children who experience intimate partner violence (IPV) has received less attention than their emotional-behavioral outcomes. Drawing upon data from 615 (48.4% female) 10-year-old Australian-born children and their mothers (9.6% of mothers born in non-English speaking countries) participating in a community-based longitudinal study between 2004 and 2016, this study examined the associations between IPV in infancy and cognition in middle childhood (at age 10). Results showed that IPV in the first 12 months of life was associated with lower general cognitive ability and poorer executive attention but not working memory skills. IPV in middle childhood (in the 10th year postpartum) was not associated with cognition. This study provides evidence for the long-term impact of early life exposure to IPV on children's cognition, and points to the importance of early intervention to optimize development.  相似文献

The implementation of science reform must be viewed as a systems-level problem and not just focus on resources for teachers and students. High-capacity instructional leadership is essential for supporting classroom science instruction. Recent reform efforts include a shift from learning about science facts to figuring out scientific phenomena in which students use science practices as they build and apply disciplinary core ideas. We report findings from a research study on professional development (PD) to support instructional leaders' learning about the science practices. After participating in the PD, the instructional leaders' familiarity with and leadership content knowledge of the science practices significantly improved. Initially, principals used their understandings from other disciplines and content neutral visions of classrooms to make sense of science instruction. For example, they initially used their understandings of models and argument from ELA and math to make sense of science classroom instruction. Furthermore, some principals focused on content neutral strategies, like a clear objective. Over the course of the PD workshops, principals took up the language of the science practices in more nuanced and sophisticated ways. Principals' use of the language of the science practices became more frequent and shifted from identifying or defining them to considering quality and implementation in science classrooms. As we design tools to support science, we need to consider instructional leaders as important stakeholders and develop resources to specifically meet their needs. If the science feels too unfamiliar or intimidating, principals may avoid or reframe science reform efforts. Consequently, it is important to leverage instructional leaders' resources from other disciplines and content neutral strategies as bridges for building understanding in science. We argue that the science practices are one potential lever to engage in this work and shift instructional leaders' understandings of science instruction.  相似文献

Although the presence of toys in childhood has remained steady for decades, the types of toys that fill children's toy boxes have changed, especially over the last 10–15 years. Many of today's toys are marked by technological enhancements, from a shape sorter driven by a singing bear to robotic plastic animals designed to match a toddler's favorite television show. Although examining the effects of these changes is still an unexplored area, research to date suggests that there may be costs to the quality of caregiver–child interaction when using these toys together. This leads to two possibilities: (1) the design of the enhancements themselves hurt interactions; or (2) these toys can still be beneficial to interactions, but caregivers simply need to be aware of the potential pitfalls. In this study, we explore whether providing caregivers with a subtle cue about the potential negative impacts of technological toys on caregiver–child interaction affects their behavior.  相似文献

In this article visual technologies and their use in three reconstructions after an incident are linked with accountability issues. Conclusions are drawn on the relation between administration, the choice of technology to create and distribute visual occurrences, and society and how visualizations are used to frame accountability issues.  相似文献

This study investigated the relationship between psychopathology and shame. Three hundred and thirty-one Secondary 2 students from Singapore participated in the study. All students completed a self-report questionnaire consisting of the Anxiety and Depression scales of the Behavior Assessment System for Children (BASC), the short version of the Aggression Questionnaire (AQ), and the Internalized Shame Scale (ISS). As predicted, students in the comorbid group at-risk for anxiety, depression and aggression, had significantly higher shame scores compared with at-risk students in all the other three single-disordered groups (anxiety-only, depression-only, or aggression-only) as well as students in the control group. Also, as expected, the control group scored significantly lower compared to all other single-disorder groups and the comorbid group. Implications of these findings with regard to comorbidity of psychopathology and its relationship to shame, classroom interventions, as well as implications pertaining to teachers' and counsellors' work with at-risk students will be discussed.  相似文献

The U.S. government technical report is a primary means by which the results of federally funded research and development (R&D) are transferred to the U.S. aerospace industry. However, little is known about this information product in terms of its actual use, importance, and value in the transfer of federally funded R&D. Little is also known about the intermediary-based system that is used to transfer the results of federally funded R&D to the U.S. aerospace industry. To help establish a body of knowledge, the U.S. government technical report is being investigated as part of the NASA/DoD Aerospace Knowledge Diffusion Research Project. In this article, we summarize the literature on the U.S. government technical report and present the results of a survey of U.S. aerospace engineers and scientists that solicited their opinions concerning the format of NASA Langley Research Center (LaRC)-authored technical reports. To learn more about the preferences of U.S. aerospace engineers and scientists concerning the format of NASA LaRC-authored technical reports, we surveyed 133 report producers (i.e., authors) and 137 report users in March–April 1996. Questions covered such topics as: (a) the order in which report components are read; (b) components used to determine if a report would be read; (c) those components that could be deleted; (d) the placement of such components as the symbols list; (e) the desirability of a table of contents; (f) the format of reference citations; (g) column layout and right margin treatment; and (h) writing style in terms of person and voice. Mail (self-reported) surveys were used to collect the data. The response rates for report producers (i.e., authors) was 68% and for users, was 62%.  相似文献
