Classical and contemporary statements about family and community suggest mutually reinforcing connections between these two life domains. However, in their search for greater niche building, scholars have largely overlooked such links because of their adherence to specific traditions. This article considers the public-private sphere debate, a tradition associated primarily with family studies. This tradition holds that individuals experience life as discrete social spheres. Using this tradition as a framework for critique, this study examines individuals' association with family and community via an empirical test of family life satisfaction and community satisfaction. Particular attention is also given to urban and rural differences and similarities in family life and community. Data were drawn from a nationally representative sample of adults from the USA. The multivariate analysis revealed a reciprocal relationship between family life satisfaction and community satisfaction. Findings are discussed in light of the public-private sphere debate and urban and rural realities. Les énoncés classiques et contemporaines sur la famille et la communauté suggèrent des rapports qui se renforcent mutuellement entre ces deux domaines de la vie. Pourtant, dans leur recherche de se faire une place dans le monde universitaire, les spécialistes ont en grande partie ignoré de telles liaisons à cause de leur adhésion aux traditions spécifiques. Cet article considère le débat entre les sphères publiques et privées, une tradition associée principalement aux études de familles. Cette tradition soutient que les individus font l'expérience de la vie comme sphères sociales discrètes. En employant cette tradition comme structure pour la critique, cette étude examine l'association des individus avec la famille et la communauté par une épreuve empirique de la satisfaction de la vie familiale et de la satisfaction de vie communitaire. Cette recherche tient compte aussi des différences et des ressemblances urbaines et rurales dans la vie familiale et communautaire, et elle se base sur des données d'un échantillon nationalement représentatif d'adultes des Etats-Unis. L'analyse multivariate a révélé un rapport réciproque entre la satisfaction de la vie familiale et la satisfaction de la vie communautaire. Les découvertes se présentent à la lumière du débat des sphères publiques-privées et des réalités urbaines et rurales. 相似文献

During the migration intervals 1965–1970, 1970–1975, and 1975–1979, families that migrated from Standard Metropolitan Statistical Areas (SMSAs) to nonmetropolitan areas and from central cities to suburban rings were larger in mean size than families that composed the respective counterstreams. Mean family sizes declined sharply for all groups throughout the period, but absolute differentials between opposing streams increased slightly. In terms of the selective attraction of families by size, nonmetropolitan net in-migration was very similar to suburbanization within SMSAs. A considerable portion of recent nonmetropolitan net gains resulted from the exchange of larger in-migrant families for smaller outmigrant families. 相似文献

This paper presents a natural extension of Bayesian decision theory from the domain of individual decisions to the domain
of group decisions. We assume that each group member accepts the assumptions of subjective expected utility theory with respect
to the alternatives from which they must choose, but we do not assume, a priori, that the group as a whole accepts those assumptions.
Instead, we impose a multiattribute utility independence condition on the preferences of the group with respect to the expected
utilities of its actions as appraised by its members. The result is that the expected utility of an alternative for the group
is a weighted average of the expected utilities of that alternative for its members. The weights must be determined collectively
by the group. Pareto optimality is not assumed, though the result is consistent with Pareto optimality. 相似文献

This article provides some views on the statistical design and analysis of weather modification experiments. Perspectives were developed from experience with analyses of the Santa Barbara Phase I experiment summarized in Section 2, Randomization analvses are reported and compared with previously published parametric analyses. The parametric significance levels of tests for a cloud seeding effect agree well with the significance levels of the new corresponding randomization tests, These results, along with similar results of others, suggest that parametric analyses may be used as approximations to randomization analyses in exploratory analyses or reanalyses of weather modification experimental data. 相似文献

In many environmental management problems, the construction of occurrence maps of species of interest is a prerequisite to their effective management. However, the construction of occurrence maps is a challenging problem because observations are often costly to obtain (thus incomplete) and noisy (thus imperfect). It is therefore critical to develop tools for designing efficient spatial sampling strategies and for addressing data uncertainty. Adaptive sampling strategies are known to be more efficient than non-adaptive strategies. Here, we develop a model-based adaptive spatial sampling method for the construction of occurrence maps. We apply the method to estimate the occurrence of one of the world’s worst invasive species, the red imported fire ant, in and around the city of Brisbane, Australia. Our contribution is threefold: (i) a model of uncertainty about invasion maps using the classical image analysis probabilistic framework of Hidden Markov Random Fields (HMRF), (ii) an original exact method for optimal spatial sampling with HMRF and approximate solution algorithms for this problem, both in the static and adaptive sampling cases, (iii) an empirical evaluation of these methods on simulated problems inspired by the fire ants case study. Our analysis demonstrates that the adaptive strategy can lead to substantial improvement in occurrence mapping. 相似文献
