The contributions included in this issue demonstrate the variety of ways in which participatory and interpretive methods are transforming the field of psychology and clarify the integration of the personal and political commitments of the authors within their research. A number of issues remain to be negotiated, however, before these methods take their full place in the field. This conclusion considers a few of these issues, including an examination of how these approaches demand a fundamental reassessment of validity in psychological research. It also considers the critical issue of the ownership of knowledge, and proposes a reframing of the ethical guidelines for research in the field. Finally, it invites further discussion and debate around the issues raised in this issue. 相似文献

This article shows how admission and enrollment processes affect the interpretation of simple validation studies of academic performance. In a competitive market for students, optimal behavior of admissions committees and applicants drives the simple correlation between test scores and performance toward zero, regardless of the relationship in the population of prospective students. Data from our university's MBA program support the prediction that applicants exhibit a higher correlation between test scores and undergraduate GPAs than do current students. This suggests that standard validation studies will understate the importance of GMAT scores in predicting performance of potential MBA students. (JEL C24 , I121 , C52 ) 相似文献

Bayesian inference for pairwise interacting point processes 总被引:1,自引:0,他引:1
Pairwise interacting point processes are commonly used to model spatial point patterns. To perform inference, the established frequentist methods can produce good point estimates when the interaction in the data is moderate, but some methods may produce severely biased estimates when the interaction in strong. Furthermore, because the sampling distributions of the estimates are unclear, interval estimates are typically obtained by parametric bootstrap methods. In the current setting however, the behavior of such estimates is not well understood. In this article we propose Bayesian methods for obtaining inferences in pairwise interacting point processes. The requisite application of Markov chain Monte Carlo (MCMC) techniques is complicated by an intractable function of the parameters in the likelihood. The acceptance probability in a Metropolis-Hastings algorithm involves the ratio of two likelihoods evaluated at differing parameter values. The intractable functions do not cancel, and hence an intractable ratio r must be estimated within each iteration of a Metropolis-Hastings sampler. We propose the use of importance sampling techniques within MCMC to address this problem. While r may be estimated by other methods, these, in general, are not readily applied in a Bayesian setting. We demonstrate the validity of our importance sampling approach with a small simulation study. Finally, we analyze the Swedish pine sapling dataset (Strand 1972) and contrast the results with those in the literature. 相似文献

Couple and therapist perspectives about the use and process of reflecting team practice were analyzed using ethnographic research. A domain analysis was performed on postession interviews from both couples and therapists, and on field notes from each therapist. Seven couples and five therapists were interviewed at least twice over a 4-month period concerning their reactions to and perceptions of reflecting team practice. Six domains concerning reflecting team practice emerged from the analysis: (a)benefits of its use, (b) effects of gender, (c)recommended use, (d) contraindicated use, (e) the importance of creating spatial separateness between couple and team members, and (f) sequences of communication between the couple and team members that elicit change. The latter two domains described the process of reflecting team practice (i.e., steps in how it is used and how it is implemented). The role of ethnog rahy in reflecting team practice and in family therapy research is discussed. 相似文献

In light of recent military court decisions, this article asks whether the Uniform Code of Military Justice should be revised
to encompass batteries which do not satisfy the present nineteenth century definition of grievous bodily harm. In answering
this question, the article first traces the evolution of the military law of battery. Current medical views on the consequences
of a criminal attack, particularly the psychic effects of violence, are then explored, concluded with a discussion of the
competing considerations which should affect any decision to change the law.
He has also been a visiting Distinguished Professor of Law at the U.S. Military Academy and has written numerous articles
on civil-military relations. 相似文献

Howard E. Gruber is currently Adjunct Visiting Professor of Psychology at Teachers College, Columbia University, New York. He is one of the world's foremost experts on the creative process. Gruber was educated at Brooklyn College and at Cornell University, Ithaca, USA, where he received a Ph.D. in 1950 in psychology. His interest in the history of science, particularly in the work of Charles Darwin, led to several important discoveries about the creative process and to additional study of developmental psychology in Geneva, Switzerland with Jean Piaget.Gruber taught at Queens University (Canada) and at the University of Colorado, USA. He was Chair of the Psychology Department in the Graduate Faculty of the New School for Social Research, New York and Co-director at the Institute for Cognitive Studies of Rutgers University, USA. From 1983 to 1988 he was Professor of Genetic Psychology at the University of Geneva. He has been a Guggenheim Fellow and a Fellow of the Ford Foundation for Higher Education.Gruber's book, Darwin on Man: A Psychological Study of Scientific Creativity (2nd ed.) (1981) received the Phi Beta Kappa Award for books in science, was recognized by the New York Times Book Review as one of the seven best books of the year, and was nominated for the National Book Award. The Essential Piaget (1977/1995) (written and edited with Jacques Vonèche) is considered the most authoritative anthology of Piaget's work. Gruber's most recent book, co-authored and co-edited with Doris B. Wallace, is Creative People at Work: Twelve Cognitive Case Studies (1989). 相似文献

Most sociologists and penologists tend to shy away from studying inmate attitudes toward homosexuality and homosexuals. Researchers within the corrections field who focus on prison sexuality typically conduct their research on consensual samesex sexual behavior and sexual coercion. The focus of the present study, however, was to ascertain female inmates' attitudes toward homosexuality and homosexuals while exploring the role ofseveral predictor variables on their attitudes. Specifically, the authors examine the relationship between female inmate homosexual behavior and attitudes toward homosexuality and homosexuals. Because of the number of items pertaining to attitudes toward homosexuality and homosexuals, factor analysis was conducted to examine whether the items measured similar constructs. Results ofthe factor analysis revealed two distinct factors/issues:civil/personal rights and personal deviance models. The mostsalient, and only statistically significant, variables in the civil/personal rights model were age, homosexual activity prior to incarceration, and homosexual activity during incarceration. Homosexual behavior during incarceration was the only statistically significant predictor of the personal deviance model. 相似文献

The development of preventive interventions targeting adolescent problem behaviors requires a thorough understanding of risk and protective factors for such behaviors. However, few studies examine whether different cultural and ethnic groups share these factors. This study is an attempt to fill a gap in research by examining similarities and differences in risk factors across racial and ethnic groups. The social development model has shown promise in organizing predictors of problem behaviors. This article investigates whether a version of that model can be generalized to youth in different racial and ethnic groups (N=2,055, age range from 11 to 15), including African American (n=478), Asian Pacific Islander (API) American (n=491), multiracial (n=442), and European American (n=644) youth. The results demonstrate that common risk factors can be applied to adolescents, regardless of their race and ethnicity. The findings also demonstrate that there are racial and ethnic differences in the magnitudes of relationships among factors that affect problem behaviors. Further study is warranted to develop a better understanding of these differential magnitudes. 相似文献
