价值观的传播是一个缓慢的过程,在当前工业文明向生态文明过渡的时期,如何有效地提升民众的生态意识是值得探讨的问题。以生态审美意识传播为切入点,通过了解国内外主流的室内环境生态评估指标体系的前后变化,总结当前室内环境生态评估的变化趋势及其主要特征;从指标体系的变化中分析生态审美价值观的渗透方式,探讨当代室内环境生态评估对生态审美价值观传播的促进作用。最后,通过实验设定针对室内传统营造技艺应用的评估工具,并且在评估工具的使用过程中展示传播的模式与效用,通过评估反馈再一次验证室内环境生态评估对生态审美价值观的正向传播作用。 相似文献

Does life satisfaction moderate the effects of stressful life events on psychopathological behavior during adolescence? 总被引:1,自引:0,他引:1
Psychologists within a positive psychology framework have proposed the existence of a set of psychological strengths that buffer against the development of psychopathology. To date, most research efforts in positive psychology have focused on adults. This longitudinal study tested the prediction that adolescents' judgments of life satisfaction moderate the influence of stressful life events on the subsequent development of psychopathological behavior. Using a sample of 816 middle and high school students, the study demonstrated support for the moderational model for externalizing behavior outcomes, but not internalizing behavior problems. Specifically, adolescents with positive life satisfaction (vs. those who were dissatisfied with their lives) were less likely to develop later externalizing behaviors in the face of stressful life events. The study also revealed that adolescent life satisfaction reports show moderate stability across a one-year time frame and independently predict subsequent externalizing behavior even while controlling for prior levels of externalizing behavior...

Introduces the current issue of the American Psychologist, which examines the ramifications of the Brown vs. Board of Education decision and its sequelae over the last 50 years, with a special focus on the mixed role of psychological research and practice. Despite the great strides toward a more just society since May 17, 1954, inequities remain in schooling, in social relations, and in economic opportunity. How will history judge American psychology 50 years from now vis-a-vis the possibilities it helped create via Brown? The articles in this special issue suggest several important directions of research and action our field will need to take if the verdict of history is to be a positive one.

Presents an obituary for Nicholas Hobbs. Just at the end of his stellar career of public service through psychology, Nick Hobbs received very appropriate honors showing that psychologists and many others knew what a precious national resource his life had been. Only days before his death from cancer on January 23, 1983, he participated in the dedication of the Nicholas Hobbs Laboratory of Human Development of the Peabody College for Teachers of Vanderbilt University, part of the Kennedy Center for Research on Education and Human Development that he founded and directed at its beginning. Two years earlier, he had received two parallel American Psychological Association (APA) awards--one for Distinguished Contributions to Psychology in the Public Interest and another for Distinguished Professional Contributions "utilizing psychological knowledge in the public interest and social policy." As the citations and testimonials on these occasions variously noted, Nick gave creative, responsible, and effective service to the institutions that he helped administer, to the Southern region from which he sprang, to the APA, and to the profession of psychology, but above all to the nation's children and youth, especially those who grew up with disadvantage and difficulty.

Racial and ethnic identity development have been important topics in counseling psychology research for the last four decades. At present, however, there appears to be some confusion and debate regarding the quality of theory and measurement in the topical area. The present article serves as an introduction to this Journal of Counseling Psychology special section on "Racial and Ethnic Identity in Counseling Psychology: Conceptual and Methodological Challenges and Proposed Solutions." A rationale is provided for the special section, the place of racial and ethnic identity scholarship is located within the history of multicultural counseling research, and the invited special section contributions by K. O. Cokley (2007), J. E. Helms (2007), J. E. Trimble (2007), S. M. Quintana (2007), J. S. Phinney and A. D. Ong (2007), and J. G. Ponterotto and J. Park-Taylor (2007) are introduced.
