A simulation model is constructed of choice between a discrete number of non-dominated alternatives. The long-run goals of the decision maker are assumed to be consistent with a hypothetical preference structure which satisfies assumptions of completeness, transitivity and additive independence for an ideal set of criteria. The use of additive value functions to aid the decision maker in this choice is simulated for a variety of contexts and under a number of non-idealities such as the omission of criteria, confounding of criteria and inconsistent responses. It is found that ideal preference orderings are well identified by additive value functions provided that the non-idealities are moderate and that sufficient effort is put into modelling changing marginal values for different levels of performance. One of the potentially most sensitive areas is that of shifts in the decision maker's reference points as a result of the types of preference information asked.  相似文献

Despite empirical support for “Self-control theory” in criminology, there is controversy about how self-control should be operationalized. Working within the framework of “self-control theory,” we investigated if violence and criminal behaviors are associated with nine distinct dimensions of cognitive control in a community sample of young men (n = 654) living in peri-urban townships in South Africa. Cognitive control was assessed using the Behavior Rating Inventory of Executive Function. Multivariate statistical analysis was used, to identify associations between violence and criminality, and deaggregated measures of nine distinct components of cognitive control. Fifteen percent of the sample reported recent violence, 27% had been in physical fights with family/friends in the preceding 6 months, 10% reported being arrested, 4% reported forced sexual contact, and 26% reported intimate partner violence (IPV). Controlling for substance use and sociodemographic variables, contact with the criminal justice system and violence were associated with deficits in all domains of cognitive control. Forced sexual contact was associated with behavioral dysregulation. IPV was associated with behavior dysregulation and executive control dysfunction. Future studies might utilize deaggregated measures of self-control to provide further insight into links between particular components of cognitive control and various forms of offending and violence.  相似文献

This essay discusses five recent books, written in French, that contribute to refection in environmental ethics. Francophone literature on the topic is marked by resonant and divergent concerns, and rooted in a geography, politics, and history different from North America and marked by distinctive lines of intellectual influence. Jean‐Claude Eslin proposes recovering ecological resources from the Christian tradition and also suggests imagining new images of God: notably, God as pilote rather than artisan. Dominique Bourg takes a multi‐disciplinary approach that emphasizes the spiritual conditions for relating to the world ecologically and economically; he argues for sobriété (austerity) as a spiritual disposition and an economic model. Baptiste Morizot develops diplomacy as an ethical, political, and spiritual model for cohabiting with wolves, whose return to the French countryside has been highly controversial. Nastassja Martin offers an anthropological study of the indigenous Gwich’in community of Fort Yukon, Alaska that accentuates the mix of Protestant missional influences and Gwich’in spiritual affirmations and practices at play in their relationship to the nonhuman world. Attending to this literature may helpfully decenter anglophone debates and enrich their conceptual vocabulary.  相似文献

ABSTRACT

This research challenges the claim that engaging in formal volunteering improves health. Using data for the 50 American states pertaining to 2015–2016, multiple regression equations with differing control and entry order demonstrated the capacity of state resident neuroticism to eliminate relations between state volunteering rates and state health outcomes. In Study 1, with state SES, White population percent, urban population percent, and health environment considered and controlled, volunteering accounted for 11.5% of state health variance. However, with neuroticism entered between the demographic controls and volunteering, neuroticism accounted for 18.0% but additional variance accounted for by volunteering was reduced to 0.7%. Similarly, in Study 2, with data for those 65 and older, the results were replicated. It is speculated that higher neuroticism produces social anxiety that discourages volunteering and fosters poorer health at both the individual and the state level for the general population and for those 65 and over.  相似文献
