Presents the citations, biographies, and selected bibliographies of the 2007 recipients of the American Psychological Association's Awards for Distinguished Contributions to the Public Interest. The Awards for Distinguished Contributions to Psychology in the Public Interest recognize persons who have advanced psychology as a science and/or profession by a single extraordinary achievement or a lifetime of outstanding contributions in the public interest. Two awards are given: one to a psychologist who has made a significant contribution to the public interest in the early stages of his or her career, and the second to a senior psychologist. The 2007 recipients of these awards are Gary W. Harper and Larke N. Huang, respectively. The Award for Distinquished Contributions to Research in Public Policy is given to a psychologist who has made a distinguished empirical and/or theoretical contribution to research in public policy, either through a single extraordinary achievement or a lifetime of work. This contribution may consist of such factors as research leading others to view specific national policies differently; research demonstrating the importance of the application of psychological methods and theory to public policy; or research clarifying the ways in which scientific knowledge of human behavior informs public policy. The 2007 recipient of this award is Vickie M. Mays. (PsycINFO Database Record (c) 2010 APA, all rights reserved)  相似文献

Beverly Greene, recipient of the Award for Distinguished Senior Career Contributions to Psychology in the Public Interest, has a long history of distinguished contributions in the public interest through her research, scholarship, teaching, practice, and consultation. Her work raises the visibility of many populations that have been overlooked and marginalized in the broader society as well as within psychology and offers new models for theoretical, empirical, and practical approaches. Her mentorship has reached innumerable people around the world, and her creative and influential contributions have moved the field in new directions. Provided here are a citation, biography, and selected bibliography of Greene's works. Also provided is her paper, entitled "The use and abuse of religious beliefs in dividing and conquering between socially marginalized groups: The same-sex marriage debate," a version of which she delivered at the American Psychological Association's annual convention.

The awards for Distinguished Contributions to Psychology in the Public Interest recognize persons who, in the opinion of the Committee on Psychology in the Public Interest Awards, have advanced Psychology as a science and/or profession by a single extraordinary achievement or a lifetime of outstanding contributions in the public interest. These contributions might include the identification or solution of significant social problems; unusual initiative or dedication to activity in the public interest; or the integration of the science and~or profession of psychology with social action in a manner beneficial to all. Each year the Committee presents two of these awards. The first is given to a senior psychologist," the second recognizes an outstanding psychologist who has made a significant contribution to the public interest in the early stages of his or her career. For purposes of the second award, recipients may not have held a PhD for more than 15 years. Members of the 1989 Committee are George Albee (Chair), Julia Ramos-Grenier, Vera Paster, Bonnie Strickland, Logan Wright, and Raymond Fowler.

For a sample of 242 freshmen, test and retest profiles on the SVIB were compared on grade changes, and letter grade and group pattern shifts, using Powers' D-score method, rank correlation, and ratings of the extent of interest changes by counselors (validity criterion). The stability measures were all significantly intercorrelated with the validity criterion (.55 to .68). (PsycINFO Database Record (c) 2010 APA, all rights reserved)  相似文献

The concurrent validity of the MVII was investigated with over 1000 vocational high school boys in Grades 9 and 12 in Buffalo, New York, schools. Scores of boys in particular trade curricula were checked against relevant MVII scales. At Grade 12, the food, electrical, and printing trade choices were well predicted; students in building trade, machinist, and mechanical programs were not well spotted. Similar results, but less encouraging, were found for the Grade-9 sample. With 1 student sample only (electrical), aptitude test data were unrelated to MVII scores. Students with "high" academic or shop school averages earned higher MVII criterion scale scores than did others. (PsycINFO Database Record (c) 2010 APA, all rights reserved)  相似文献
