By using economics, welfare and social network factors as frames of reference, this study aims to explore the relationship between these three factors and net migration to various US states. Adopting related variables collected from official aggregate data, this study first utilizes Logit Regression analysis to draw out seven variables that best explain net migration to the various states, then employs these variables in LISREL analyses to build a model explaining the factors influencing net migration to the various US states. Concretely, this research obtained the following findings: (1) the seven variables ‐‐ the average rate of net migrants of 2002–2005, Medicaid, federal aid, employment rate, non‐poverty population rate, and SSI subsidy ‐‐ all significantly affected (p < 0.01 or p < 0.05) net migration in 2006; (2) the main influences on net migration for the various states are, from highest to lowest, social network, economic, and welfare factors. More specifically, a better explanation is that, through the social network factor, economic and welfare factors exert an increased influence on the net number of migrants; and (3) as for the influence of social network factors on the number of net migrants, the social network factor for the previous year was found to best explain domestic migration flows, while the social network factor for the previous three‐to‐four years best explained international migration flows. 相似文献

We develop a regression decomposition technique for hazard rate models, where the difference in observed rates is decomposed into components attributable to group differences in characteristics and group differences in effects. The baseline hazard is specified using a piecewise constant exponential model, which leads to convenient estimation based on a Poisson regression model fit to person-period, or split-episode data. This specification allows for a flexible representation of the baseline hazard and provides a straightforward way to introduce time-varying covariates and time-varying effects. We provide computational details underlying the method and apply the technique to the decomposition of the black-white difference in first premarital birth rates into components reflecting characteristics and effect contributions of several predictors, as well as the effect contribution attributable to race differences in the baseline hazard . 相似文献

Abstract Interest group conflict, power, and values have been prominent in recent attempts to analyze law as social control. The role of fact beliefs in creating, interpreting and administering legal norms has been relatively neglected, especially in the few efforts toward theories of law in society. Both fact beliefs and value beliefs are here related to legal norms, and also to group interests, power and conflict. Law is conceived of as the formal social control of the political state, a definition that does not at all require acceptance of Austin's view of law as commands of the sovereign. The forced choice between power elite and structural-functional theories is avoided, since law operates in a wide variety of power situations. The subjective meanings of interest group actions directed toward legal norms are seen as consisting of value and fact beliefs, an approach of particular promise in analyzing law and social change. 相似文献

Numerous studies suggest spirituality and subjective well-being (SWB) are positively associated. However, critics argue that popular spirituality instruments—including the Daily Spiritual Experiences Scale (DSES)—contain items that conflate religiosity/spirituality (R/S), prosociality and SWB. Advocates of the DSES retort that, despite this concern, the available evidence confirms a single underlying factor. The current paper evaluates the DSES’s development, factor structure, reliability and convergent and predictive validity using a community sample. Despite the full DSES scale’s excellent internal reliability, two related factors—theism and civility—are identified. Both scales are reliable and converge meaningfully with related R/S measures. As expected, given previous findings, the full DSES scale predicts higher SWB yet the two subscales display divergent associations. This finding offers new insights into the DSES and raises questions about the claimed belief-as-benefit effect. 相似文献

Despite the prevalence of goal setting in organizations, researchers have not thoroughly examined the implications of goal setting to work outcomes in interdependent work settings. A field survey (n= 442) assessed the relation of goal setting and goal sharing, the extent to which others are aware of an individual's work goal, to performance and conflict across varying levels of task interdependence. The results of moderated regression analyses demonstrate that in highly interdependent tasks, the use of goal setting resulted in lower performance levels. Moreover, goal setting and goal sharing in highly interdependent tasks resulted in individuals' reporting more somatic symptoms. The results are discussed in terms of clarifying the role of goal setting for interdependent tasks. 相似文献

Culturally embedded differences in self-interested behavior and perceptions of trust violate the universal assumption of moral hazard held by transaction cost economic theorists. A model of transaction cost advantage is derived and propositions developed using the cultural value diversity literature to test the universal assumptions of transaction cost economics. 相似文献

Gender, Race, and Perception of Environmental Health Risks 总被引:17,自引:2,他引:17
This paper reports the results of a national survey in which perceptions of environmental health risks were measured for 1275 white and 214 nonwhite persons. The results showed that white women perceived risks to be much higher than did white men, a result that is consistent with previous studies. However, this gender difference was not true of nonwhite women and men, whose perceptions of risk were quite similar. Most striking was the finding that white males tended to differ from everyone else in their attitudes and perceptions–on average, they perceived risks as much smaller and much more acceptable than did other people. These results suggest that sociopolitical factors such as power, status, alienation, and trust are strong determiners of people's perception and acceptance of risks. 相似文献

This study investigated the relationships among social ties, task-related communication, and first industrial job performance of a group of young engineers by utilizing a cooperative (coop) engineering program as a natural study. The coop arrangement allowed the researcher to examine the work behavior of these young engineers with similar academic training who were working on comparable work assignments in the same set of organizations.The study found that the job performance of the coop engineers was related to the pattern of work- related communication but not the total number of contacts. Specifically, high performance new engineers were integrated more broadly into the interpersonal communication networks than low performance new engineers. Moreover, high performance new engineers exhibited communication patterns similar to those of high performance veteran engineers working on similar types of technical work. Social ties with the company staff was found to be related positively with job performance, but social ties with other coop engineers was found to be related negatively with job performance, a result which challenges an implicit assumption often made by researchers and managers about the organizational socialization of newcomers. Overall, this study provides an integrative framework for relating social ties and communication as key factors for understanding the job performance of young engineers and presents a methodology for assessing their organizational assimilation. 相似文献

QALYs versus WTP. 总被引:2,自引:1,他引:2
James K Hammit 《Risk analysis》2002,22(5):985-1001
Quality adjusted life years (QALYs) and willingness to pay (WTP) are alternative measures of the value of reductions in health risk that are often used in evaluating environmental, health, and safety practices. Although both methods are based on individual preferences, the underlying assumptions differ. The different bases yield systematically different conclusions about the relative value of reducing health and mortality risks to individuals that differ in age, preexisting health conditions, income, and other factors. The choice of which method to use depends on judgments about what constraints should be placed on individual preferences and what factors should be considered in aggregating preferences across people. 相似文献
