Establishing validity in evaluation: The Canadian Indian school evaluations

A key concern of evaluators, particularly those using naturalistic procedures, is establishing the validity of the evaluation results. In this article, an approach designed to strengthen the validity of the case study method of evaluation is outlined. Five aspects of this approach are identified that accomplish this. They are the evaluator selection procedure, the method of setting out the evaluation expectations, the use of on-going feedback, the use of multiple perspectives, and the wide involvement of various audiences.     

The Repeatability of Uncertainty and Sensitivity Analyses for Complex Probabilistic Risk Assessments

The performance of a probabilistic risk assessment (PRA) for a nuclear power plant is a complex undertaking, involving the assembly of an accident frequency analysis, an accident progression analysis, a source term analysis, and a consequence analysis. Each of these analyses is, in itself, quite complex. Uncertainties enter into a PRA from each of these analyses. An important focus in recent PRAs has been to incorporate these uncertainties at each stage of the analysis, propagate the subsequent uncertainties through the entire analysis, and include uncertainty in the final results. Monte Carlo procedures based on Latin hypercube sampling provide one way to perform propagations of this type. In this paper, the results of two complete and independent Monte Carlo calculations for a recently completed PRA for a nuclear power plant are compared as a means of providing empirical evidence on the repeatability of uncertainty and sensitivity analyses for large-scale PRA calculations. These calculations use the same variables and analysis structure with two independently generated Latin hypercube samples. The results of the two calculations show a high degree of repeatability for the analysis of a very complex system.     

SOCIAL LEARNING THEORY AND ALCOHOL BEHAVIOR AMONG THE ELDERLY

Research directly testing Akers's social learning theory has been thus far confined to teenage drug, drinking, and smoking behavior. This study extends the application of social learning theory to older adults' alcohol behavior. Data were gathered through face-to-face interviews of 1,410 people sixty years of age or over living in New Jersey and Florida in either retirement (age homogeneous) or age-integrated communities. A social learning model of differential association, differential reinforcement, and definitions is supported by findings on elderly drinking behavior. As is true for younger age groups, drinking among the elderly is related to the norms and behavior of one's primary groups, one's own attitudes toward (definitions of) alcohol, and the balance of reinforcement for drinking.     

Employment and unemployment patterns in the U.S. and Europe, 1973–1987

Employment trends in the United States and Europe are compared using Bureau of Labor Statistics data. These data set the stage for a discussion of the difference in employment growth between the U.S. and Europe. Also included are some elements that may partly explain the U.S. and European differences in job growth. In conclusion, labor market problems still remain even with the tremendous job growth in the U.S.     

The geolinguistics of /l/ vocalization in Australia and New Zealand

Recent work in comparative sociolinguistics marks a re–engagement of variationists studying language change in progress with geography. In this study of the vocalization of /l/ in nine speech localities in Australian and New Zealand English, the geographical, the linguistic and the social constraints on variation are all included in the quantitative analysis. The usual identification of the starting point of change as the factor that is quantitatively ‘more’ is challenged by variable constraint hierarchies associated with speech localities as well as by the identification of Christchurch as the place of the origin of the sound change. Neither the gravity nor the urban hierarchy models of diffusion explain the geographical pattern of the sound change; a number of place effects are proposed as potential explanations, including the geographical variability of the vigorousness of the change. Variable isoglosses representing discontinuities in the dataset are mapped; they reveal the subtle patterns of sociolinguistic variation that mark the difference between Australian English and New Zealand English.     

Community Differences in the Association Between Parenting Practices and Child Conduct Problems

Various hypotheses were identified regarding the manner in which community context might influence the association between two dimensions of parenting—control and corporal punishment—on child conduct problems. The authors used hierarchical linear modeling with a sample of 841 African American families to test these hypotheses. Consistent with the evaporation hypothesis, the results indicated that the deterrent effect of caretaker control on conduct problems becomes smaller as deviant behavior becomes more widespread within a community. The findings for corporal punishment supported the normative parenting argument. Although there was a positive relationship between caretaker corporal punishment and child conduct problems in communities where physical discipline was rare, there was no association between the two variables in communities where physical discipline was widely prevalent. These results suggest that a particular parenting strategy may be more effective in some neighborhood environments than others. The theoretical implications of this view are discussed.     

Political Modernities: Disentangling Two Underlying Dimensions of Institutional Differentiation

This article recommends that we recover two old contrasts from the history of social thought in order to facilitate the recently renewed discussion of multiple variants of European political modernity. Recovering them greatly aids in clarifying the different "modernizing" paths that the European-system polities took during the state-consolidation and nation-building periods of the "long nineteenth century." Specifically, the basic polity forms delineated in this article capture strikingly well the distinctive "institutional logics" and political cultures of the Anglo, Nordic, Germanic, and French orbits, legacies enduring through the 1960s and beyond. Clarifying these polity forms also helps in isolating underlying institutional changes occurring in the contemporary (post-World War II) period (current institutional convergence, for example).
