This research reexamines the meaning of occupational prestige scores from the social psychological perspective of identity theory. Using comparable data for Canada and the United States, it analyzes the degree to which the education and income levels of occupations influence occupational prestige judgements by evoking affective associations (feelings about the goodness, powerfulness, and liveliness of occupational identities), as well as the extent to which these social sentiments are independent determinants of prestige. There has been a longstanding controversy about the normative content of occupational prestige scores. We find that moral worthiness (as measured by the Evaluation dimension of the semantic differential) is a determinant of the prestige of occupations with low and middle but not high levels of education and income. We also find that the impact of education on prestige scores is direct and cognitive, while a considerable proportion of the total effect of income is processed through feelings about the potency of occupations. The results for the two countries are very similar. One exception is that moral worthiness is a more important determinant of prestige in the United States than in Canada. We connect this finding to the literature comparing value differences between the two countries. 相似文献

The purpose of this study was to demonstrate the development of safety, permanency, and child well-being indicators by using administrative data sets as well as by using these indicators as tools for evaluating Florida's Community-Based Care (CBC) initiative. Longitudinal data from 37 counties including 4 counties that implemented community-based care were examined in this study. The results of the study indicated that the overall performance of CBC counties is at least as good as the performance of their comparison run by the state counties. The findings that emerged from this study may provide important lessons for developing a performance measurement system in the child welfare field. 相似文献

Correspondence to David Pentecost, Department of Child and Adolescent Mental Health, Finchley Memorial Hospital, Granville Road, London, N12 0JE. E-mail: david.pentecost{at}lineone.net Summary Four hundred and forty social work practitioners for children,including those of Guardian ad Litem status, were surveyed regardingtheir knowledge and perceptions concerning attention deficithyperactivity disorder (ADHD). Questionnaires were distributedto the social workers via managers in seven boroughs in thesouth-east of England. The majority of practitioners in thesample were able to correctly identify the key diagnostic criteriaclosely associated with the condition. Over a third of respondentswere unsure of the appropriateness of treatment with stimulantmedication while the large majority felt that psychosocial interventionsinvolving the families were appropriate. Length of post-qualifyingexperience was found to be a crucial variable influencing bothknowledge about ADHD and the preferences for interventions forthe condition. Less than three out of ten practitioners regardedit as important to involve the Children with Disabilities Teams(CDTs) in such cases and a similar proportion were unaware oflocal resources that may support these children and their families.The results are discussed in relation to previous studies, implicationsfor social work practice and training and the role of CDTs inthe field. 相似文献

Abstract This paper presents some recent data on why organizations invest in exercise and physical fitness programmes for their stiff. These data suggest that, owing to a lack of evaluation studies, organizations act mainly on the basis of assumption and belief. However, from a subsequent review of the available literature on the personal and organizational effects of such programmes, it appears that these assumptions and beliefs are not altogether unfounded. The paper concludes by discussing the ways in which exercise and employee fitness programmes might help die individual and their organization in terms of the management of health at work. 相似文献

The election in 1997 of a new Labour Government and the publication of the Wild Mammals (Hunting With Dogs) Bill provided an opportunity for the re-opening of the public and political debate about hunting wild animals with hounds in Britain. A significant new dimension to the 1997/98 debate was the increasing emphasis on the claimed economic importance of hunting and its provision of rural jobs. This paper critically examines the nature of such claims. It argues that economic claims about hunting should be assessed in the context of a changing rural economy, and demonstrates how the pro-hunting lobby's predictions of job losses from banning hunting are difficult to sustain. It suggests that if our starting point is a concern for the rural economy, then hunting is a minor issue compared with other pressing issues of the late 1990s such as, for example, European rural policy reforms. Moreover, a wider economic analysis suggests that hunting wild mammals imposes other social costs, in the form of disruption and damage to property, which could be avoided by switching to non-quarry hunts. The paper concludes by examining the reasons for the rise of this economic dimension to the hunting debate. 相似文献

The thimbleberry aphid,Masonaphis maxima (Mason) lives on patches of plants that support 3,4 or 5 generations depending on site and weather. The life cycle requires
sexual females and males to produce overwintering eggs. The eggs hatch in the spring to produce the first ’fundatrix’ generation;
subsequent generations are produced parthenogenically. Males and other morphs are produced by wingless virginoparae, but sexual
females are produced by ’gynoparae’, a winged morph that is specialized to produce only sexual females. The fundatrices have
no indication of the number of generations that the plants will support in the current year. There are two fundatrix types
that coexist in different ratios depending on the number of generations supported by the patch the previous year. One type
produces sexual females in generations 3 and 5, and males in generations 4 and 5; the other type produces sexual females in
generations 4 and 5, and males in generations 3, 4 and 5. The dimorphism adapts the aphid to its heterogeneous and somewhat
unpredictable environment. The role of sex in the maintenance of the dimorphism is discussed. This is the first report of
fundatrix polymorphism and consequent differential sex expression in aphids. 相似文献

This paper tackles the problem of handling uncontrolled heterogeneity due to unobserved influences on the decision process of spatial choice. It concentrates upon a discrete-time/‘random-effects’ approach to the problem of unobserved heterogeneity and documents parametric and non-parametric methods of specifying and estimating models which can cope with unobserved heterogeneity. 相似文献

We consider approximate inference in hybrid Bayesian Networks (BNs) and present a new iterative algorithm that efficiently
combines dynamic discretization with robust propagation algorithms on junction trees. Our approach offers a significant extension
to Bayesian Network theory and practice by offering a flexible way of modeling continuous nodes in BNs conditioned on complex
configurations of evidence and intermixed with discrete nodes as both parents and children of continuous nodes. Our algorithm
is implemented in a commercial Bayesian Network software package, AgenaRisk, which allows model construction and testing to
be carried out easily. The results from the empirical trials clearly show how our software can deal effectively with different
type of hybrid models containing elements of expert judgment as well as statistical inference. In particular, we show how
the rapid convergence of the algorithm towards zones of high probability density, make robust inference analysis possible
even in situations where, due to the lack of information in both prior and data, robust sampling becomes unfeasible. 相似文献

Through examining the case of people with epilepsy (which, as we demonstrate, has an ambiguous status in relation to both popular and academic conceptions of disability) we explore the fluid, negotiable and contingent nature of identity and, in particular, the identification as ‘disabled’. Disability, we argue, cannot be reduced to either biology or social oppression, or even primarily to biological or social factors: it is the outcome of a complex interaction between a multiplicity of factors – biological, environmental, social, psychological, cultural and political – which will interact and be experienced differently by different people, at different times and in different situations. Rather than conceiving of disability in ‘all or nothing’ terms and of differing explanations as competing and mutually exclusive, it would be more productive to see them as partial and potentially complementary contributions to the better understanding of a complex and multifarious reality. 相似文献
