Blessed is he who expects nothing, for he shall never be disappointed—Benjamin FranklinBased on our risk-value framework, this paper presents extensions for the disappointment models that were originally proposed by Bell (1985) and Loomes and Sugden (1986). We provide explicit functional forms for modeling the effect of disappointment on risky choice behavior that generalizes Bell's work and lends tractability to the efforts of Loomes and Sugden. Our generalized disappointment models can explain a number of decision paradoxes, and offer additional insights into nonexpected utility preferences based on the intuitive notions of disappointment and risk-value tradeoffs.  相似文献

ABSTRACT

Self-neglect (SN) and frailty in older adults is associated with increased disability and mortality. Despite these commonalities, there have been no studies objectively assessing frailty in older adults who SN. This secondary analysis classified frailty in N = 37 older adults with Adult Protective Services validated SN using the Fried Frailty Phenotype (FFP) of weight loss, weakness, exhaustion, activity level, and walking speed. Overall, 3% were classified as robust, 62% as prefrail, and 35% as frail. Most (72%) were overweight/obese, with clinically significant decreases in activity level (60%) and walking speed (97%). Compared to the original FFP population, older adults who SN exhibit important differences in frailty phenotypes, and finding that the largest percentage of older adults who SN were prefrail may indicate a critical opportunity for intervening in this population to reduce future functional decline and mortality.  相似文献

During the 1990s, 23 states implemented family cap policies as a means to reduce the incidence of out-of-wedlock births among welfare recipients. Using Current Population Survey data from 1989 to 1999, we examine the impact of family cap policies on the birth rates of single, less-educated women with children. We use the first five states that were granted waivers from the Department of Health and Human Services to implement family caps as natural experiments. Specifically, we compare trends in out-of-wedlock birth rates in Arkansas, Georgia, Indiana, New Jersey and Virginia to trends in states that did not implement family caps or any other waivers prior to the Personal Responsibility and Work Opportunity Reconciliation Act. We employ several techniques to increase the credibility of results from our natural experiment, such as the inclusion of multiple comparison groups, controls for differential time trends, and difference-in-difference-in-differences estimators. Our regression estimates generally do not provide evidence that family cap policies reduce the incidence of out-of-wedlock births among single, less-educated women with children.  相似文献

This article presents Solomon Islands village women’s opinions about gender norms. It explores their perceptions of their ability to be involved in leadership roles and decision-making, and their analysis of how they conceive of their abilities changing. It attempts to unravel the ‘push-pull’ experience for Solomon Islands rural women—a push towards modernity equated with gender equity and development, and the pull of traditional gender roles for women embedded in notions of what it means to be a good Solomon Islander woman. It concludes that women’s empowerment must be viewed as a journey that encompasses women’s strategic and practical interests relating to agency in a variety of locations. This article contributes to understanding some aspects to women’s empowerment and how international NGOs and other development entities may have a role in creating space for women’s self-reflection, public commentary and visibility in secular social space.  相似文献

Most research on remittances focuses on economic motivations, with little emphasis on the social contexts in which the remittance economy operates. Through an analysis of in‐depth interviews with migrant workers in a London hotel and hospital, we examine how migrants’ familial and social relationships in both sending and receiving countries inform the decision to send remittances. We suggest that remittances are a mechanism through which migrants are able to fulfil multiple obligations to families and places of origin, while also enhancing their own economic status and future. First, satisfying the cultural expectation of sending remittances helps migrants maintain their social worlds at “home”. Second, we observed that both positive and negative changes in power and resources influence the decision to send remittances by motivating migrants to invest in their social position in either their home or receiving country. In sum, we argue that the migrants’ social experience in the United Kingdom might be just as predictive of remittance behaviour as their economic and social status in the country of origin. We, therefore, call for a need to move beyond the often one‐sided concern with development by concentrating on the overlapping social worlds of migrants.  相似文献

The most widely used techniques for identifying the varying effects of stressors involve testing moderator effects via interaction terms in regression or multiple‐group analysis in structural equation modeling. The authors present mixture regression as an alternative approach. In contrast to more widely used approaches, mixture regression identifies varying effects without reliance on tests of moderator variables, such as using interaction terms or multiple group analyses. In many instances, the use of mixture regression also more effectively tests higher order and multiple interactions. A mixture regression example is presented using 214 families from the Fragile Families and Child Wellbeing study, half of whom had experienced paternal incarceration. Whereas typical regression and moderator analyses fail to find an effect or varying effects, mixture regression identified 4 classes uniquely influenced by the incarceration.  相似文献

An overview is given of some salient demographic characteristics in the dramatically changing socio-economic environment of France. Examination of social security and medical insurance provision shows how social welfare benefits have become more or less vital in the French family's maintenance of improved living standards. It is concluded that French social security services now compare favourably with provisions in other countries, but that birth-rate problems and other social effects of rapid developmental change remain to be overcome.  相似文献

We show simple yet optimal results to update the inventory/capacity levels, expected profit, fill rates, and service levels of substitutable resources in response to an updating of the mean demand forecasts for the resources. We find that a change in the mean demand of one resource does not affect the optimal inventory level of any other resource. The results are obtained for demands with location‐scale distribution, and for a revenue structure satisfying a triangle property such that the manager will always use the inventory of a resource to meet her own demand first before using it for substitution. The results for updating the performance measures also extend to managers who maintain non‐optimal inventory/capacity levels. Implications for procurement, sales and operational planning, and multi‐store operations are discussed.  相似文献

This study examined longitudinal change in adolescents' prosocial behavior toward family, friends, and strangers. Participants included 491 mother–child dyads (average age of child at Time 1 = 11.5, 67% European American). Growth mixture modeling suggested that prosocial behavior toward family was generally stable or decreased over time, while prosocial behavior toward friends increased over time. However, findings highlighted unique developmental trajectories within subgroups of adolescents for prosocial behavior toward family and friends and found that maternal warmth and adolescent sympathy, self‐regulation, and gender consistently distinguished between groups. Discussion focuses on the need for a more multidimensional approach to prosocial development.  相似文献

The authors introduce factor mixture modeling (FMM) and its implications for assessing varying degrees of shared reality in families. FMM extends the typical factor analytic model that uses a set of observed indicators to identify an unobservable factor and its structure. FMM examines the possibility a sample is a mixture of “classes,” each with unique factor structures. To demonstrate, varying factor structures of father involvement are identified using father, mother, and child reports as observed indicators. Three classes were identified and relate to varying degrees of shared reality regarding the father. Predictors and outcomes of these classes are modeled. The class in which the child's view most overlapped with his or her parents' view was predicted by higher child agreeableness and higher levels of maternal depressive symptoms. As hypothesized, membership in this class predicted lower levels of parental conflict and fewer parental attempts to involve their children in their conflicts.  相似文献
