Social cognitive models examining academic and career outcomes emphasize constructs such as attitude, interest, and self-efficacy as key factors affecting students’ pursuit of STEM (science, technology, engineering and math) courses and careers. The current research examines another under-researched component of social cognitive models: social support, and the relationship between this component and attitude and self-efficacy in math and science. A large cross-sectional design was used gathering data from 1,552 participants in four adolescent school settings from 5th grade to early college (41 % female, 80 % white). Students completed measures of perceived social support from parents, teachers and friends as well as their perceived ability and attitudes toward math and science. Fifth grade and college students reported higher levels of support from teachers and friends when compared to students at other grade levels. In addition, students who perceived greater social support for math and science from parents, teachers, and friends reported better attitudes and had higher perceptions of their abilities in math and science. Lastly, structural equation modeling revealed that social support had both a direct effect on math and science perceived abilities and an indirect effect mediated through math and science attitudes. Findings suggest that students who perceive greater social support for math and science from parents, teachers, and friends have more positive attitudes toward math and science and a higher sense of their own competence in these subjects. 相似文献

In recent times, issues surrounding change have become increasingly important in the study of political analysis. This is especially true within strains of new institutionalism such as historical institutionalism and the 'Varieties of Capitalism' approach. However, although this has led to a sensitising towards the temporal dimension, the spatial dimension has been relatively ignored. This is arguably problematic, as a fuller understanding of space and the spatiality of social and political relations would lead to more coherent and accurate analyses of political phenomena that currently characterise historical institutionalism. Indeed at an ontological level, drawing on work within the natural sciences and geography, it is impossible to talk of time without reference to spatiality and of space without reference to temporality. This short article reviews some of the more prominent historical institutionalist literature that deals with change and renders explicit the problematic conceptualisation of space, and consequently time, which underpins their analyses. Drawing on Massey and Sayer, it proceeds to outline briefly a relational conception of space and the difference that space makes to political analyses. 相似文献

Major disasters represent infrequent events that often require response organizations to vicariously learn from the experiences of others in order to improve their operations. A primary mechanism for such knowledge diffusion is the different practitioner and empirical journals for the organizational fields that comprise disaster response. A review of the literature for the law enforcement field, however, reveals that little attention is given to how these organizations manage actual disasters. In particular, the presentation of organizational experiences, whether through case studies or other methodologies, is very limited in the practitioner and empirical literature of this field. This represents a considerable problem for improvements of disaster response operations given that law enforcement agencies represent a key component in such efforts. The research presented in this article is an effort to fill this knowledge gap and thereby facilitate organizational learning to improve future law enforcement disaster response activities. The authors traveled to Mississippi and Louisiana after Hurricane Katrina to examine the response efforts of state and local law enforcement agencies to the storm. The findings from this research are reported here in a lessons‐learned format to inform law enforcement disaster response policy. 相似文献
