The Board for the Advancement of Psychology in the Public Interest confers the Award for Distinguished Contribution to Research in Public Policy upon 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 might include 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 scientific knowledge of human behavior informs public policy. One of the two winners of this award is Linda A. Teplin. She pioneered the introduction of rigorous psychological field methodologies into real-world criminal justice contexts. Her widely cited studies of how police interact with citizens they perceive as mentally disordered have become the gold standard for research on police behavior. Her more recent but equally definitive work on the prevalence of mental disorder among urban jail populations has firmly established the extraordinary need for mental health services within these community institutions. Her creation of an empirically derived scale to facilitate the referral of inmates for psychological evaluation has the potential to transform jail mental health services in the United States.

The Board for the Advancement of Psychology in the Public Interest presents two awards annually to persons who, in the estimation of the Committee on Psychology in the Public Interest Awards, have advanced psychology as a science and/or profession by a single extraordinary contribution or a lifetime of outstanding contributions in the public interest. One award is presented to a senior psychologist, and the other recognizes a psychologist who has made a significant contribution to the public interest less than 15 years after the receipt of his or her degree. The citation, biography, and selected bibliography of one of the 1993 recipients of this award, Parick H. DeLeon, are presented here.

Interactive design has come about as a result of the intermingling of disciplines. As a consequence, the language it uses has become blurred - borrowed or stolen with little restraint from elsewhere. Though particular terms have become ubiquitous, the original concepts that lie behind them have been lost. This means that all too frequently they are no longer knowingly used. Usman Haque sorts the wheat from the chaff and brings clarity to bear on the vocabulary and thinking behind interactivity. Copyright © 2007 John Wiley & Sons, Ltd.  相似文献

Most of the former studies on cavitation erosion (CE) in corrosive media were carried out in NaCl solutions. In contrast, the effects of and ions, which are dominant anions in most rivers of China, on cavitation erosion have not been investigated systematically. In this paper, the cavitation erosion behaviour of 20SiMn low alloy steel in Na2SO4 and NaHCO3 solutions was investigated by using a magnetostrictive-induced CE facility. The micrographs of damaged surfaces were observed by scanning electron microscope (SEM). It was found that the CE rate of 20SiMn low alloy steel in 0.003% Na2SO4 solution was higher than that in 0.003% NaCl solution, but in 0.03%, 0.3%, and 3% solutions their CE rate was almost the same. The CE rate of 20SiMn low alloy steel in 0.003-3% NaHCO3 solutions was higher than that in the equivalent 0.003-3% Na2SO4 and 0.003-3% NaCl solutions, which may be related to stress corrosion cracking or corrosion fatigue mechanism in NaHCO3 solutions. The role of corrosion was analyzed by using polarization curves, electrochemical impedance spectroscopy (EIS), linear polarization resistance and the corrosion potential with or without cavitation. Independent of the test media, cavitation shifted the corrosion potential in the positive direction and strongly enhanced the cathodic current density in the polarization curves. In the interaction of cavitation erosion and corrosion, the corrosion-induced erosion component was predominant. Cavitation also greatly reduced the magnitude of impedance though the initial impedance under cavitation conditions in 3% NaHCO3 solution was almost one order larger than that in 3% Na2SO4 solution.  相似文献
