Economic instability, social changes, and new social policies place economic insecurity high on the scholarly and political agenda. We contribute to these debates by proposing a new multidimensional, intertemporal measure of economic insecurity that accounts for both its multiplicity and its dynamism. First, we develop three theory-driven, multidimensional measures of economic insecurity. Principal Components Analysis validates the measure. Second, we develop a dynamic approach to insecurity, using longitudinal data and a newly revised headcount method. Third, we then use our new measures to analyze the distribution of insecurity in Europe. Our analysis shows that insecurity is widespread across Europe, even in low-inequality, encompassing welfare states. Moreover, it extends across income groups and occupational classes, reaching into the middle classes.

Following perinatal loss, a type of ambiguous loss, bereaved couples struggle with and experience distress due to various forms of ambiguity. Moreover, the juxtaposition of their grief with society's minimization often disenfranchises them from traditional grieving processes. The purpose of this study was to explore sources of ambiguity and disenfranchised grief related to perinatal loss. Audio-taped interviews with 13 bereaved couples at 2, 6, and 13 months following the death of their fetus or infant were analyzed. Several categories of ambiguity and disenfranchised grief emerged, pertaining to: (a) the viability of the pregnancy; (b) the physical process of pregnancy loss; (c) making arrangements for the remains; and (d) sharing the news. This study uncovers the many sources of ambiguity and disenfranchised grief that bereaved couples face in interactions with family, friends, society, and healthcare professionals. These insights may inform healthcare professionals in their attempts to ease distress related to perinatal loss.  相似文献

Insulin-like growth factor 1 (IGF-1) signaling modulation has been associated with increased lifespan in model organisms, while high levels of circulating interleukin-6 (IL-6) are a marker of disability and mortality. In the prospective, population-based "Treviso Longeva"--TRELONG Study from Italy (n = 668, age range 70-105.5 years at baseline, followed for seven years) we investigated the effects of survival on the IGF-1 receptor (IGF-1R) gene polymorphism rs2229765, the IL-6 gene promoter polymorphism rs1800795, and plasma concentrations of IGF-1 and IL-6, alone or in combination. We found a sex-dependent effect for the IGF-1R rs2229765 polymorphism, as male carriers of the homozygous A/A genotype survived longer, while the IL-6 rs1800795 genotype did not influence overall or sex-specific longevity. Higher IL-6 levels were more detrimental for survival among males than females, while IGF-1 had no dose-response effect. These findings sustain the hypothesis that sex-specific longevity relies on detectable differences in genetic and biochemical parameters between males and females.  相似文献

This article examines the experiences of seven diverse therapists in a supervision course as they wrestled with the real-world application of multicultural supervision. Existing literature on multicultural supervision does not address the difficulties that arise in addressing multicultural issues in the context of the supervision relationship. The experiences of six supervisory candidates and one mentoring supervisor in addressing multicultural issues in supervision are explored. Guidelines for conversations regarding multicultural issues are provided.  相似文献

The purpose of this study was to conduct an action-oriented evaluation of an in-home family therapy program serving families deemed at risk for the placement of children in foster care. In this study, feedback was solicited from both clients and therapists. Results indicate "duality" associated with several aspects of in-home family therapy, including the opportunity to observe families in their own homes versus the vulnerability some families feel when therapy is conducted in-home; therapists suggesting that sufficient training is required for in-home family therapy to be effective versus clients' opinions that therapists' lived experiences are more relevant; and the importance of the therapeutic alliance versus feelings of abandonment upon termination. Implications for researchers and practitioners are discussed.  相似文献

This article provides a mathematical model to support management in making decisions about cost-delivery trade-offs in the case of cost-delivery flexibilities in distribution logistics. The optimization problem can be modeled as a bi-objective periodic vehicle routing problem, which is known as NP-hard. In the periodic vehicle routing problem considered in this study, no delivery patterns are pre-defined, instead the patterns are the result of the optimization process of the model. In addition, delivery time flexibilities are incorporated in the model. A heuristic solution method for realistic problem sizes is based on the tabu search procedure, and a real case study illustrates the applicability of the solution concept.  相似文献

In the late 1940's a similar problem occurred in the work of three sociologists, working in three countries, on three similar sets of data. Natalie Rogoff, David Glass and G6sta Carlsson all faced the problem of making sense of data on intergenerational occupational mobility. A matrix of frequencies of occupations of respondents by occupations of fathers could be converted, in an obvious and straightforward fashion, into matrices of inflow and outflow percentages. Their joint problem arose in comparing inflow percentages across rows or outflow percentages across columns. The problem was that, as sociologists, concerned with the extent that origins in socially meaningful categories influenced destinations in the same socially meaningful categories, they were stuck with occupational categories that differed from one another dramatically in size. A secondary (though hardly trivial) problem was the fact that, in all their data, the two marginal distributions, the respondents' generation and the fathers' ‘generation’, were notably dissimilar — a consequence of both differential fertility and a general upward shift in the occupational distributions of the three countries. All sought a technique that would ‘make the two time periods comparable with respect to occupational structure’.  相似文献
