OBJECTIVE: The purpose of this study is to examine processing of facial emotions in a sample of maltreated children showing high rates of post-traumatic stress disorder (PTSD). Maltreatment during childhood has been associated independently with both atypical processing of emotion and the development of PTSD. However, research has provided little evidence indicating how high rates of PTSD might relate to maltreated children's processing of emotions. METHOD: Participants' reaction time and labeling of emotions were measured using a morphed facial emotion identification task. Participants included a diverse sample of maltreated children with and without PTSD and controls ranging in age from 8 to 15 years. Maltreated children had been removed from their homes and placed in state custody following experiences of maltreatment. Diagnoses of PTSD and other disorders were determined through combination of parent, child, and teacher reports. RESULTS: Maltreated children displayed faster reaction times than controls when labeling emotional facial expressions, and this result was most pronounced for fearful faces. Relative to children who were not maltreated, maltreated children both with and without PTSD showed enhanced response times when identifying fearful faces. There was no group difference in labeling of emotions when identifying different facial emotions. CONCLUSIONS: Maltreated children show heightened ability to identify fearful faces, evidenced by faster reaction times relative to controls. This association between maltreatment and atypical processing of emotion is independent of PTSD diagnosis.  相似文献

This research draws upon merged national databases containing federal crime statistics, community demographic data, and campus characteristics. The study displays the trends in campus crime since 1974, and using 1990 data, examines the relationships between three measures of campus crime and 23 predictors developed for this study. The results show that campus rates of both violent crime and property crime are falling, especially since 1985. Moreover, students are considerably safer on campus than in the cities and communities surrounding them. The lowest average crime rates are found at two-year colleges, while the highest overall rates are at medical schools and health science centers. None of the community characteristics, including community crime and poverty rates, are significantly associated with campus crime. While campus organizational measures in general are more highly related to campus crime than are student characteristics, we find differences in the patterns of variables associated with violent crime versus property crime. Factors associated with property crime are partially consistent with existing theory on criminal activity. Factors associated with violent crime are more complex and difficult to predict.An earlier version of this paper was the winner of the regional Best Paper Award from the North East AIR annual meeting in Bolton Landing, N.Y., November 1993. It was presented again at the Association for Institutional Research Forum, New Orleans, Louisiana, May 1994.  相似文献

This article presents a ‘knowledge ecosystem’ model of how early career academics experience using information to learn while building their social networks for developmental purposes. Developed using grounded theory methodology, the model offers a way of conceptualising how to empower early career academics through (1) agency (individual and relational) and (2) facilitation of personalised informal learning (design of physical and virtual systems and environments) in spaces where developmental relationships are formed, including programmes, courses, events, community, home and social media. It is suggested that the knowledge ecosystem model is suitable for use in designing informal learning experiences for early career academics.  相似文献

The collective consciousness of effective groups of researchers is characterized by shared understandings of their research object or territory. In this study, we adopted a phenomenographic approach to investigate information technology (IT) research, and its objects and territories, as they are constituted in the experience of IT researchers. Semi‐structured interviews were conducted with researchers representing different sub‐disciplines. Analysis revealed the variation in meaning associated with the idea of IT research; and the awareness structures through which participants experience variation in ways of seeing the object and territories of IT research. Eight ways of seeing IT research were found. The outcomes of our project appear to make visible the changes and developments that are an essential part of the character and experience of contemporary IT research.  相似文献

A cowse‐integrated programme of library instruction has been developed for the School of Civil Engineering at the Queensland University of Technology, Australia; library instruction being one of the means selected to improve the research efforts of fourth year project students. The programme has been developed through consultation between the Civil Engineering Research Project Coordinator and the Civil Engineering Reference Librarian. Its aims are derived from those established for the fourth year research projects. Attention is focussed on the nature of the programme and the impact of instruction on fourth year research project students. Students who had received extended library instruction were compared with students from the previous year. Evidence suggests that the instruction has improved the information seeking behaviour of the students and their literature reviews.  相似文献

This paper presents the concept of critical flexibility as an alternative to eclecticism in instructional design. Eclecticism is often viewed as a persuasive alternative to theoretical orthodoxy (i.e., rigid use of a single perspective or process) due to the openness and flexibility it purports to offer. In contrast, the authors argue that eclecticism ignores or discourages critical reflection regarding background understanding (e.g., implicit assumptions and values) and perpetuates the lack of openness and flexibility commonly associated with orthodoxy. Critical flexibility, as an alternative to eclecticism, emphasizes an awareness of background understanding, but construes it as capable of being explicated, critically examined, adjusted in specific contexts, and refined or developed over time to facilitate increasingly flexible and effective design practices. The authors clarify the nature of critical flexibility as a general way of being involved in the design process, suggest how it helps overcome the traditional theory–practice split, and discuss several of its implications for scholarship and training.  相似文献
