Current child protective service policies encourage family preservation and reunification. Yet little is known about how mothers accused of child neglect experience being labeled neglectful or how this influences compliance with child protective services (CPS) service plans. This paper reports the results of a case study of mothers' perceptions of being labeled neglectful. Drawing on symbolic interactionist theories of identity, interviews with sixteen mothers and sixteen child protective service caseworkers, and content analysis of interview data obtained, this paper describes the strategies mothers employ to resist the stigma of being labeled a neglectful mother, strategies that ultimately put them at odds with child protection goals. Findings suggest that mothers' identity preservation and maintenance have powerful implications for CPS policy.  相似文献

In the previous installment of this column, Donnice Cochenour wrote about Project Muse, Johns Hopkins University Press's project to provide electronic access to its journals. This column will explore OCLC's collaboration with publishers who are making traditional print publications available electronically. Serials Review interviewed Andrea Keyhani, Manager of Electronic Publishing at OCLC, about traditional print publishers' interests in electronic distribution of journals, OCLC's solution to publishers' migration to electronic distribution, enhancements to their Guidon software, and libraries' costs and archive concerns.  相似文献

Summary Frequent shell exchanges among hermit crabs imply the enigmatic circumstance that large crabs frequently obtain large shells from smaller crabs. This seeming anomaly is explored as a key to the shell resource system. It is hypothesized to reflect how, where, and how often shells become available to the crabs. Shells become available infrequently, as snails die, and are available to the crabs for only a brief time before they become inaccessible. The standing crop of empty shells is almost always low and is irrelevant to rates of shell turnover in the crab population. Crabs are most likely to encounter shells of the wrong size, and the chance of encountering a shell of the desired size decreases as a crab grows. Snails and crabs are usually found on different portions of the shore; thus, crabs must make “foraging trips” for shells. Under this regime of shell supply, a crab will get a suitable shell the fastest when it accepts any fresh shell that is larger than its initial shell. It can then trade with other crabs to improve its shell fit. This behavior will make small crabs into a regular source of large shells for large crabs, and a shell exchange ritual will be strongly favored because both participants will benefit. Shells are an unusual resource because they are the object of both competitive and mutualistic interactions. This ambiguous quality is revealed in the intraspecific and interspecific responses of crabs to each other and to shells.  相似文献

Given only a random sample of observations, the usual estimator for the population mean is the sample mean. If additional information is provided it might be possible in some situations to obtain a better estimator. The situation considered here is when the variable whose mean is sought is composed of factors that are themselves observable. In the basic case, the variable can be expressed as the product of two, independent, more basic variables, but we also consider the case of more than two, the effect of correlation, and when there are observation costs.  相似文献

This article identifies similarities among three approaches to dealing with rule breaking: the procedural justice model, the restorative justice model, and the study of moral development. Each argues that the long-term goal when dealing with rule breaking is to motivate rule breakers to become more self-regulating in their future conduct. This goal is undermined by punishment-focused models of sanctioning. Sanction-based models, which dominate current thinking about managing criminals, have negative consequences for the individual wrongdoer and for society. It is argued that greater focus needs to be placed on psychological approaches whose goal is to connect with and activate internal values within wrongdoers with the goal of encouraging self-regulatory law-related behavior in the future.  相似文献

Life satisfaction is referred to a cognitive, judgmental process (Diener et al. in J Pers Assess 49:71–75, 1985), in which person’s quality of life is globally assessed according to his/her chosen criteria (Shin and Johnson in Soc Indic res 5:475–492, 1978). Thus, life satisfaction is a conscious cognitive judgment, based on the comparison of one’s life with a self-imposed standard or set of standards, which lead to a global assessment of life (Pavot and Diener in Psychol Assess 5:164–172, 1993). Among the many scales developed to measure life satisfaction, the Satisfaction With Life Scale (SWLS, Diener et al. in J Pers Assess 49:71–75, 1985) is one of the global life satisfaction scales more often used in the research arena. It is composed of five items assessing global life satisfaction, using a Likert type response format. The aim of this paper is to validate the Portuguese version of the SWLS via confirmatory factor analysis, with a sample of 1,003 elderly from Angola. Reliability, factorial and criterial validity estimates are presented. Overall, the results shown that the scale had an adequate one-factor confirmatory solution, satisfying reliability indices, and adequate criterion-related validity when assessed in a sample of Angolan elderly. The discussion relates the results with existing literature and posits the contributions of the paper: firstly, it offers the researchers on life satisfaction in Portuguese-speaking contexts a brief, self-rated measure of satisfaction with life that has sound psychometric properties, validity, and reliability; secondly, it is the first confirmatory validation of the scale in Portuguese.  相似文献
