Intermarriage among heterogeneous social groups has often been studied as a process of assimilation. The present paper extends this research through a unique application of macro-structural propositions of intermarriage (Blau et al., 1982) to a nineteenth century American frontier population. Variants of these propositions are presented, used to address age patterns of nuptiality, and tested through a longitudinal application. Results support the utility of macro-structural theories in analyses encompassing initial community formation as well as assimilation of later arriving immigrants. Analyses illustrate both the assimilation of initially arriving immigrant groups on the frontier and the initial emergence of new heterogeneities in the established native population and later arriving immigrants.  相似文献

Household composition choices of older unmarried women   总被引:4,自引:0,他引:4  
This article extends previous research on the household composition of older unmarried women, using a statistical model that treats each of a woman's surviving children as a distinct potential provider of a shared household. Additional possibilities--living alone, living with other nuclear-family relatives, and living with others--are also recognized, providing a varied range of household-structure opportunities for older women. The approach allows us to identify individual child attributes associated with the propensity to coreside with the older unmarried mother. The results confirm earlier findings regarding the importance of income, age, and disability status as determinants of the household composition of older women. We find, however, that unmarried children, especially sons, are more likely to share a household with an elderly mother than are married children. Working reduces the likelihood that a married daughter will live with her older mother. Overall, the findings suggest that the attributes, more so than the sheer numbers, of living children influence the household structure of their mothers.  相似文献

This study investigates the relative priority of various job shop dispatching rules for various shop utilization levels under both deterministic and stochastic assumptions with regard to processing times. The primary criterion for evaluation is that of percentage on time completion. The results indicate that an assumption of accurately predetermining actual operation times in most cases is not likely to weaken the analysis and impact of research studies which are performed using such an assumption. Also conclusions indicate that the ranking of dispatching rules according to their effectiveness varies significantly with shop utilization levels.  相似文献

Participatory research: Three models and an analysis   总被引:2,自引:0,他引:2  
This article examines three models of participatory research: what we call the parallel process model, the mutual engagement model, and the University of Central America (UCA) model. These models represent successively greater degrees of academic engagement with outside communities—from complementary, though not necessarily uncommitted, engagement by academic(s); to compromised full engagement between the academic(s) and the community; to institutional engagement between the entire university and the community. Our analysis outlines the tensions that may arise within participatory research between service and scholarship. We conclude that for participatory research to capture the attention and involvement of the broader discipline, it must provide a spectrum of theory, methods, and substance that sociologists find of importance independent of the participatory way in which such contributions are generated. This article is based on a paper presented at the 87th Annual Meeting of the American Sociological Association, D.L. Lawrence Convention Center, Pittsburgh, Pennsylvania, August 20–24, 1992.  相似文献

Heim and Snyder (1991) explicitly applied a multidimensional assessment and data-analytic strategy to predict husbands' and wives' depressive symptoms from measures of marital disaffection, overt marital conflict, appraisals of relationship prognosis, characterizations of the spouse, and causal attributions. For both genders, the best single predictor of depression was a measure of marital disaffection—accounting by itself for approximately one third of the variance in subjects' depressive symptoms. Additional attributional predictors of depression for married women indicated the need for therapists to support wives' assertive expression of relationship concerns and confrontation of husbands' behaviors contributing to their distress. We reiterate the complex and recursive relationships among marital difficulties, depression, congnitive processes, and their antecedents and consequences and encourage focused research on components of this intricate puzzle.  相似文献
