Sociologists have examined how structural economic change affects household social organization and generation of household income from different sources. The introduction of elements of a market economy into rural Russia in the early 1990s provides a unique opportunity to examine these relationships. Much of the work on this topic, however, has been conducted in black earth zone, agriculturally dependent regions. Less attention has been given to non‐black‐earth zone, forest resource dependent regions. This article addresses this limitation by comparing the relationships between household income generation strategies and household social organization in a 2009 survey of villages in three forest resource dependent regions in northwest Russia with findings from a 2006 survey of households in nine agricultural regions of Russia. Income generated from enterprises based on household social organization—household labor and social helping networks—is substantially greater in agriculturally dependent than in forest resource dependent regions. We discuss the implications of these findings for understanding intranational regional differences in the relationship between economic systems, household social organization, and rural household economies as well as the obstacles facing policymakers and environmentalists who attempt to shift household income generation strategies away from an environmentally harmful lumber industry to income generation activities that are less harmful to the environment.  相似文献

Despite recent increases of psychosocial programs for pediatric chronic illness, few studies have explored their economic benefits. This study investigated the costs–benefits of a family systems‐based, psychosocial intervention for pediatric chronic illness (MEND: Mastering Each New Direction). A quasi‐prospective study compared the 12‐month pre–post direct and indirect costs of 20 families. The total cost for program was estimated to $5,320. Families incurred $15,249 less in direct and $15,627 less in indirect costs after MEND. On average, medical expenses reduced by 86% in direct and indirect costs, for a cost–benefit ratio of 0.17. Therefore, for every dollar spent on the program, families and their third payers saved approximately $5.74. Implications for healthcare policy and reimbursements are discussed.  相似文献

This article describes the innovative use of a pop culture source-song lyrics to augment the teaching of qualitative methods in social work research. The use of pop culture sources as learning tools in the MSW curriculum has the potential to enhance the learning experience for students. These techniques have not been applied in the content of MSW research classes. This approach could be advantageous over other typical data sources because it is more accessible to students while also being reflective of a collective identity of people in society. Future work should assess student and educator responses to this pedagogical approach.  相似文献

The implications of constrained dependent and independent variables for model parameters are examined. In the context of linear model systems, it is shown that polyhedral constraints on the dependent variables will hold over the domain of the independent variables when a set of polyhedral constraints is satisfied by the model parameters. This result may be used in parameter estimation, in which case all predicted values of the dependent variables are consistent with constraints on the actual values. Also, the implicit constraints that define the set of parameters for many commonly used linear stochastic models with an error term yield values of the dependent variables consistent with the explicit constraints. Models possessing these properties are termed “logically consistent”.  相似文献

A laboratory experiment examined the effects of applying decision support system (DSS) technology to decision making in ill-structured problem environments under varying information conditions. Marketing executives participated in the experiment which investigated the effects of DSS availability, DSS training, and data availability on dependent variables that included: (1) the number of alternatives considered by a subject during decision making, (2) the period of time spent by a subject to complete the decision-making process, (3) the subject's perceived confidence in the decisions he or she had made, (4) the amount of data considered by a subject's during decision making, (5) the individual subject's decision processing, and (6) the subject's performance overall. Our results indicate that all three factors significantly affect the number of alternatives considered by subjects during the decision-making process. We therefore suggest that DSS training be coordinated with decision training in order to realize the potential of DSSs as described in the DSS literature.  相似文献

This note examines the sensitivity of the basic economic-order-quantity inventory model to lot-size errors when holding costs are assumed to be a strictly increasing (though not necessarily linear) function of average inventory. In particular, we show that the penalty associated with ordering either too much or too little is a function not only of the size of the error but of the shape of the holding-cost curve as well. We demonstrate that, under certain conditions, even relatively small lot-size errors can be extremely costly.  相似文献

Using data from a survey of union members, we explore how an amalgamation of two Swedish unions affects membership participation. The research literature on the topic is mostly anecdotal and speculative, suggesting that mergers might have detrimental effects on membership participation because they create large unions with centralized governance and administration. But in this study, we do not find a broad-based decline in membership participation measured before and after merger as well as in relation to a comparison union that did not merge. These results are discussed in terms of the national context of union mergers in Sweden and the ways that mergers are negotiated, presented, and implemented to preserve membership participation. An earlier version of this paper was presented at the Third International Conference on Emerging Union Structures: Reshaping Labour Market Institutions, Canberra, Australia in December 1997. The data collection for this project was supported by funds from the National Institute for Working Life in Stockholm.  相似文献

There is increasing interest in the emergence of a ‘global middle class’ in which high achieving young graduates increasingly look to develop careers that transcend national boundaries. This paper explores this issue through comparing and contrasting the aspirations and orientations of two ‘elite’ cohorts of graduates. Interviews with students at the University of Oxford, England, and Sciences‐Po, France, reveal very different ambitions and allegiances. Our Oxford respondents portray their futures as projects of self‐fulfilment as they build portfolio careers by moving from job to job and from country to country with limited social allegiances – epitomizing the nomadic worker of the transnational elite. Our Parisian respondents, on the other hand, display strong allegiances to the nation, state and civic duty. Their projects of the self involve reconciling their personal aspirations with strong allegiances to France. The paper concludes by discussing the significance of these differences. It argues that the enduring role of education in the formation of national identities should not be overlooked and that more detailed research is needed on the contextual specifity of transnationalism and the (re)production of elites.  相似文献
