In the labor market, net disadvantages of immigrants, so-called “ethnic penalties”, may stem from rather different sources, among them discrimination by employers or self-exclusion processes. This paper attempts to indirectly disentangle these two mechanisms by studying ethnic penalties from a time-related perspective. Using the EULFS 2000 ad hoc module on school-to-work transitions, a comparative event-history analysis of entry into stable higher status employment is conducted for two European countries, Belgium and Spain. These countries differ considerably in their immigration contexts and patterns of school-to-work transitions, requiring different hypotheses about the relevance of the self-exclusion mechanism. The results show that in Belgium ethnic penalties for non-EU immigrants exist and remain constant irrespective of the length of the job search. In Spain the gap between non-EU immigrants and the native-born is even more pronounced and, importantly, increases significantly over time. This leads to the conclusion that discrimination seems to be relevant in both contexts and that self-exclusion resulting from early abandonment of job search activities is a further important factor in Spain.  相似文献

This study replicated the methods of a previous review and assessed the frequency with which discussions of basic behavioral principles occurred in a sample of research and case studies published in Journal of Organizational Behavior Management. A total of 127 research and case studies published between 2006 and 2015 were reviewed; 67 included a discussion of behavioral principles. The percentage of research articles and case studies discussing behavioral principles was higher than that found in previous research. The most frequently described principle was reinforcement. Our findings also documented a higher percentage of laboratory studies discussed behavioral principles.  相似文献

We propose a model of firm reputation in which a firm can invest or disinvest in product quality and the firm's reputation is defined as the market's belief about this quality. We analyze the relationship between a firm's reputation and its investment incentives, and derive implications for reputational dynamics. Reputational incentives depend on the specification of market learning. When consumers learn about quality through perfect good news signals, incentives decrease in reputation and there is a unique work–shirk equilibrium with ergodic dynamics. When learning is through perfect bad news signals, incentives increase in reputation and there is a continuum of shirk–work equilibria with path‐dependent dynamics. For a class of imperfect Poisson learning processes and low investment costs, we show that there exists a work–shirk equilibrium with ergodic dynamics. For a subclass of these learning processes, any equilibrium must feature working at all low and intermediate levels of reputation and shirking at the top.  相似文献

Approximately 52 million Americans provide informal (unpaid) care to a family member or friend who is disabled or ill. The most common informal caregiving relationship is that of an adult child providing assistance to an aging parent. This article describes a qualitative study examining how adult daughters between the ages of 50 and 65 become caregivers to their parent or parent-in-law. Data were collected through in-depth, face-to-face interviews with 15 female caregivers. Analysis revealed that assistance provided to parents was initiated by one or more triggering event, after which participants became caregivers in either an emergent or deliberate manner.  相似文献

Few gamblers seek treatment despite the severe negative impacts prolonged gambling can have. Research surrounding the predictors of help-seeking for problem gambling is often retrospective in design and inconsistent in findings. This study prospectively investigated whether transtheoretical model (TTM) constructs (readiness to change, ratings of temptations and self-efficacy, decisional balance and processes of change) have utility in predicting help-seeking among disordered gamblers. Community-recruited disordered gamblers (N = 136; 47.06% female; mean age = 44.5 years, SD = 12.8; 80.1% Caucasian) completed three assessments of TTM constructs, help-seeking behaviour, gambling problem severity, and other potential predictors of help-seeking. Informal help-seeking was common (6-month = 71.1%; 12-month = 79.6%); however, formal help-seeking was relatively infrequent (6-month = 22.7%; 12-month = 35.1%). Logistic regression demonstrated that gambling problem severity and the social liberation process of change (i.e. endorsing public awareness of gambling problems or non-gambling role models) consistently predicted formal help-seeking. Helping relationships and counter-conditioning (i.e. engaging in other activities as a replacement for gambling) processes of change uniquely predicted informal help-seeking at 12 months. Individuals most likely to seek formal help have greater problem severity and greater readiness to address problems. Seeking informal help is less predictable but more common.  相似文献

Abstract

This article explores how, in the context of an unfolding process of neoliberalisation in India, new terrains of resistance are crystallising for subaltern groups seeking to contest the marginalising consequences of this process. We focus particularly on the emergence of India's ‘new rights agenda’ through a study of the making of the Right to Fair Compensation and Transparency in Land Acquisition, Rehabilitation and Resettlement Bill, 2013. Conceiving of the emergence of the ‘new rights agenda’ as a hegemonic process, we decipher how law-making is a complex and contradictory practice seeking to negotiate a compromise equilibrium between, on the one hand, subaltern groups vulnerable to marginalisation and capable of mobilisation; and, on the other, dominant groups whose economic interests are linked to the exploitation of the spaces of accumulation recently pried open by market-oriented reforms. The negotiation of this equilibrium, we suggest, is ultimately intended to facilitate India's process of neoliberalisation.  相似文献

Let F and G be life distributions with respective failure rate functions rF and rG and respective 100α-percentile (0 < α < 1) residual life functions qα, F, and qα, G. Distribution-free two-sample tests are proposed for testing H0: F = G against H1,α,: qα, Fqα, G and H2 α: qβ, Fqβ,G for all β ≥ α. This class of tests includes as a special case the test of Kochar (1981) for the alternative H*2: rFrG. A theorem of Govindarajulu (1976) is extended in order to obtain asymptotic normality of the test statistics. The condition qα, Fqα, G is implied by rFrG and is unrelated to the stochastic ordering FG; if F and G are Weibull distributions with respective shape parameters c1 and c2 such that 1 ≤ C1 < C2, then qα,Fqα, G for all α larger than a function of the parameters.  相似文献

Experts frequently differ on their estimates of risk associated with accidents that have a low probability of occurrence. Those who stand to benefit from siting a new facility often perceive it as acceptably safe, using expert opinion to defend their argument. Potential losers find data to suggest that the new technology is too hazardous. This paper contrasts the role of risk assessments of low probability events in siting Liquified Natural Gas (LNG) terminals in the United States and the Federal Republic of Germany. In both cases the decision process was a rather lengthy one due to conflicts between interested stakeholders. The paper discusses the potential of compensation and insurance as policy tools for facilitating negotiation. Four criteria for improving the siting process in any country are also outlined.  相似文献
