Central to many inferential situations is the estimation of rational functions of parameters. The mainstream in statistics and econometrics estimates these quantities based on the plug‐in approach without consideration of the main objective of the inferential situation. We propose the Bayesian Minimum Expected Loss (MELO) approach focusing explicitly on the function of interest, and calculating its frequentist variability. Asymptotic properties of the MELO estimator are similar to the plug‐in approach. Nevertheless, simulation exercises show that our proposal is better in situations characterised by small sample sizes and/or noisy data sets. In addition, we observe in the applications that our approach gives lower standard errors than frequently used alternatives when data sets are not very informative.  相似文献

This article seeks to develop our understanding of the agency of vulnerable groups who at first sight may not seem to have much agency in their lives. It explores the co‐constructed nature of agency in three Danish homeless shelters. Unlike earlier interview‐based studies, our research is based on naturalistic data drawn from 23 video‐recorded placement meetings. Using concepts from Goffman, we examine how versions of the neediness and worthiness of homeless people are negotiated verbally and bodily between staff and clients. We find that homeless people have to juggle two partly contradictory roles when they are given or take the roles of either a (active) citizen or a (passive) client. Clientship is actively negotiated by both parties and demonstrates the agency of homeless people: they can collaborate with (as clients) or challenge (as citizens) the staff’s attempts to formulate solutions to their troubles. We further examine how the professional ideology of client centredness affects the meeting between the two parties. However, we show that, like any discourse, client centredness has no intrinsic meaning and is played out by actors in very different ways. In work with the homeless, the discourse of client centredness is related to discourses of ‘neediness’, ‘worthiness’ and ‘value for money’ that define agency in different ways and make three different client positions available: the resolute client, the acquiescent client and the passive client.  相似文献

Reflecting teams (RTs) represent both an epistemological stance and a therapeutic technique. Most commonly associated with narrative and systemic approaches to therapy, RTs offer an outsider perspective that can bring hope and alternative narratives and perspectives for therapists and clients to explore. Relational hope is a little researched concept in the field of couple therapy research. This study explores the experience of RTs in couple relationships and the aspects of the experience that couples describe as connected to a sense of hope for their relationship. The study also considers whether difference in attachment style shows any relationship with hope in couple relationships before and after the clients’ session with a reflecting team. Couples completed questionnaires about their attachment style, demographics, and relational hope and were given the option to complete an interview about their experience with the reflecting team within 1 month of their therapy session. Our findings suggest that RTs contribute positively to hope in couple relationships particularly for clients who present with an anxious attachment style. This direction for research is important because there is very little research about hope in couple relationships despite its importance (Merolla, 2014; Snyder, 2002) and there is no research about what aspects of a reflecting team contribute to hope in couple relationships. Analysis of interviews indicates a number of features of the reflecting team feedback that were valued by clients.  相似文献

Sexual harassment is a persistent problem for women in the workplace. Prior research has explored the effects of sexual harassment on the psychological, physical and economic wellbeing of the victims. Despite the extensive research exploring the causes, most studies focus on micro‐level factors, and few studies examine the role of macro‐level factors on sexual harassment in the workplace. Using public Equal Employment Opportunity Commission (EEOC) data and a separate dataset of individual level workplace sexual harassment complaints, we test two hypotheses about sexual harassment in American workplaces. First, we show that the decline in workplace sexual harassment complaints has been uneven, with African‐American women experiencing an increased relative risk of sexual harassment in the workplace, even as overall reported harassment complaints are down. Second, we show that economic threat — operationalized in this case through unemployment rates — drives increases in sexual harassment of women in American workplaces. While the data on harassment complaints is limited, data strongly suggests that the changes are driven by shifts in underlying levels of harassment, rather than changes in the likelihood of reporting harassment.  相似文献

The article analyses why asylum‐seekers choose Hungary as an entry point to the European Union. Among the Central and Eastern European countries Hungary has been by far the most popular choice for asylum‐seekers between 2002 and 2016, yet surprisingly, it has been neglected by the literature. Using a panel dataset and fixed effects regressions, the article finds that beyond being ‘conveniently’ located on the Balkans migration route, variables related to Hungary's immigration policy are the most significant determinants of asylum‐seeker choices. The article finds no evidence to support recent claims by the Hungarian government that arrivals to the country are actually economic migrants and not asylum‐seekers; quite the contrary, the results indicate that on average asylum‐seekers entering Hungary are fleeing violent conflict in their countries of origin.  相似文献

This article analyses minimum wage violations over the period 2003–12 in ten central and eastern European countries which all have national statutory minimum wages. Using European Union Statistics on Income and Living Conditions (EU‐SILC) data and the methodology proposed by Bhorat, Kanbur and Mayet (2013), the authors measure the incidence and depth of violation. In addition, they conduct regression analyses on individual, workplace and macro‐level determinants of non‐compliance. While the incidence of violation remains relatively low, the workers that minimum wage policies seek to protect appear to be the most likely to be affected by non‐compliance. Over time, higher minimum to average wage ratios are related to a higher incidence of violation.  相似文献

The significant increase in the number of refugees entering the European Union and the low employment rates among them remain pressing issues across Europe. While previous research has mainly focused on refugee integration prospects from the policymakers’ point of view, we shift the analytical focus to how refugees perceive the introduction programme experience, examining the case of Syrian refugees to Sweden. Drawing upon semi‐structured interviews with Syrian refugees, our results suggest that the quality of language training, the complexity of the validation process for educational qualifications and the lengthy administrative procedures are perceived as important barriers hindering the access of refugees to the Swedish labour market. These barriers are differently perceived, especially by those with differing levels of education. This highlights the utility of an intersectional approach, and the continued need to explore the diversity of migrant experiences when assessing integration policies and programmes.  相似文献

Low rates of female labor force participation (LFP) have been linked to the absence of childcare policies. This article examines the degree to which extending the school day by 3.5 hours in elementary schools, a large implicit childcare subsidy, affects LFP, the number of weekly hours worked, and the monthly earnings of females with elementary‐school‐age children. To do so, we exploit within‐individual variation in access to full‐time schools and a rotating panel of households that contains 12 years of individual‐level data on labor outcomes and sociodemographic characteristics. Results from long‐difference models show that extending the school day increases mothers' labor supply, increasing LFP by 5.5 percentage points and the number of weekly hours worked by 1.8. Moreover, these increases are accompanied by a raise in monthly earnings. (JEL I25, J13, J22)  相似文献

Neoliberalism is prevalent in American life. While researchers have documented the use of neoliberal ideology in institutional and macrolevel policy contexts, they have yet to investigate how voters use neoliberal ideology to legitimate their position on economic policy. I use data from semi‐structured interviews with 85 Tucsonans about why they voted the way they did on Proposition 202 (2008): “Arizona Stop Illegal Hiring”—which sought to reregulate undocumented worker labor market access—to address this gap. I found evidence of two distinct neoliberal ideological legitimations: “fair market competition” and “individual responsibility.” Furthermore, I use these data to shed light on the debate over whether neoliberalism spans partisan affiliation or converges with American conservatism. I found that voters across party lines who supported the measure paired neoliberal legitimations with conservative legitimations. We can interpret this bipartisan use of neoliberal ideology as evidence of a neoliberal “moral economy”—or consensus about the moral principles in which market action is embedded. Evidence of this moral economy indicates that moral principles from neoliberal ideology are simultaneously bipartisan and converge with American conservatism. These findings suggest that there could be a broader moral consensus among voters concerning the legitimacy of anti‐immigration economic policies.  相似文献

We examined relations between adolescent perceptions of deviant peer behavior and delinquency as moderated by inhibitory control, planning, and decision making in the National Institute of Child Health and Human Development (NICHD) Study of Early Child Care and Youth Development at age 15 (N = 991). Adolescents reported perceptions of deviant peer behavior. Inhibitory control, planning, and decision making were assessed behaviorally. Delinquency was evaluated with a latent variable comprised of parent‐guardian perceptions of adolescent delinquency and adolescent self‐reports. Only inhibitory control moderated the relationship between deviant peer behavior and delinquency, showing that better inhibition protected against delinquency in contexts of high levels of adolescent perceptions of deviant peer behavior. Findings are discussed in the context of theories of adolescent delinquency and risk taking.  相似文献
