Messick's (1989) theory of test validity is profoundly influential (Hubley and Zumbo, 1996; Angoff, 1988) in part because it brings together disparate contributions into a unified framework for building validity arguments. At the heart of Messick's theory lies a synthesis of realism and constructivism with respect to both scientific facts and measurement. Within this synthesis there remains a tension between the evidential basis and the consequential basis for test interpretation and use. This cannot be sidestepped simply by limiting the evidential basis to test interpretation and the consequential basis to test use: Interpretation and use are not so easily held separate. The roles of constructivism and context in Messick's theory underline the inherent link between facts and values, but the assumption that facts are objective and values are subjective goes unquestioned in Messick's theory. The inherent link between facts and values combines with this assumption to produce the unresolved tension in Messick's theory. This suggests that a unified theory of test validity requires a theory of value justification.  相似文献

Parenting is a critical factor in substance abuse prevention. Positive parenting behaviors are identified as a protective factor for substance abuse among youth. Limited research exists that investigates the role of parenting practices on minority youth substance use. The present study seeks to examine correlates between parenting and recent alcohol use among African American youth. Specifically, to what extent do African American students report experiencing specific parenting behaviors that are measured by the National Household Survey on Drug Use and Health?, do specific parenting behaviors increase the risk of recent alcohol use among African American youth?, does the impact of parenting behaviors on recent alcohol use among African American youth differ based on sex (males and females) and age category (12–13, 14–15, and 16–17 years old) were examined in this study? Logistic regression analysis of the National Household Survey on Drug Use and Health was conducted to examine the research questions. Findings indicated that parenting behaviors was associated with recent alcohol among youth. Significant differences were found for males, females, 12–13, 14–15, and 16–17 years olds. Study findings demonstrate the importance of positive parenting behaviors in youth alcohol prevention. Program specialists may target parenting as a means of preventing and reducing youth alcohol use among African American youth.  相似文献

This article addresses the concern expressed by many within the Pacific Sociological Association in recent years that their regional organization is increasingly seen by Research I University sociologists as no longer meeting their professional needs, thus leading to (a) decreasing rates of membership and participation within, (b) a decline in the amount of high quality professional work associated with, and (c) a diminishment of the professional status of, the PSA. Using data gained from a membership survey of sociologists at the 29 Research I Universities in the Western Region of the United States and Canada, the empirical basis of these claims is examined, and their possible implications explored. The results of this investigation suggest that although PSA membership among faculty members at PhD-granting institutions may have declined somewhat over time, this has occurred for a number of very comprehendible reasons, some associated with but others external to the Pacific Sociological Association as a professional organization. In light of these findings, it is the main recommendation of this paper that the PSA should continue to approach this issue in a careful and reasoned manner, doing what it reasonably can to try to meet the professional needs of Research I University sociologists in the 21st century, but being mindful not to jeopardize what has made the PSA important and attractive to its growing number of other constituencies in recent years.  相似文献

A typology of life and death was investigated in relation to demographic characteristics, social comparisons, work orientation, and depressive symptoms among 240 hospice workers who replied to a mail questionnaire. Even though conceptions of life and death are part of the same life cycle, they have often been studied separately among those who work with the dying. There was evidence for the usefulness of the typology in the study of indicators of quality of life. A discriminant analysis indicated that four types (positivists, temporal optimists, resigned futurists, and negativists) were differentiated by social‐psychological and demographic characteristics. Implications for application are suggested.  相似文献

Canonical correlation has been little used and little understood, even by otherwise sophisticated analysts. An alternative approach to canonical correlation, based on a general linear multivariate model, is presented. Properties of principal component analysis are used to help explain the method. Standard computational methods for full rank canonical correlation, techniques for canonical correlation on component scores, and canonical correlation with less than full rank are discussed. They are seen to be essentially equivalent when the model equation for canonical correlation on component scores is presented. The two approaches to less than full rank situations are equivalent in some senses, but quite different in usefulness, depending on the application. An example dataset is analyzed in detail to help demonstrate the conclusions.  相似文献

This article examines some difficulties associated with the Haynes–Stone model and attempts to clarify how the model can be justified as representing the hypothesis that “quantity is demand determined and price is supply determined.” It also argues that the applications of such a model as was done by Haynes and Stone might not have resolved the controversies related to the Phillips curve and the supply function of exports (or imports).  相似文献
