Although appearance-based cues can help to diagnose physical illness, visual manifestations of mental disorder may be more elusive. Here, we investigated whether individuals could distinguish women with a serious mental disorder (borderline personality disorder) from demographically- and IQ-matched non-psychiatric controls. Participants rated mentally ill targets as more likely to have a mental disorder from photos more accurately than chance, despite not believing that such judgments were possible. The configuration of facial cues played an important role in these judgments, as interfering with the spatial relationships between facial features reduced participants’ accuracy to chance guessing. Further investigation showed similar results when participants rated the targets for specific mental disorders (borderline personality disorder, major depressive disorder) and rated the mentally ill targets as more depressed, angry, anxious, disgusted, emotionally unstable, distressed, and less happy. Moreover, the depression ratings significantly correlated with the targets’ actual depressive symptoms. Thus, individuals may be able to infer aspects of mental disorder from minimal facial cues.  相似文献

Previous research has shown uniquely high expectations among children of immigrants. However, existing studies have not focused on why children of immigrants have an expectations advantage over their native‐born counterparts or if this has changed over time. This study shows that an immigrant advantage in graduate school expectations persists among adolescent children of immigrants today. Regression analyses reveal that this advantage is largely explained by higher parental expectations, greater interest in school, and foreign language use in early childhood. We argue that these factors can be conceptualized as forms of cultural capital stemming from unique aspects of the immigrant experience that are common across immigrant families.  相似文献

This article studies the payment of wages to castle slaves at Cape Coast Castle (in current-day Ghana) in the eighteenth century. A quantitative estimate shows that the wages paid to these slaves were considerably higher than subsistence costs. A large sample of wage payments is also used in order to analyse statistically the existing wage differentials among the slaves. The results indicate that a complex wage structure had been developed in order to incentivize the slaves to work and to foster loyalty towards the slaveholder.  相似文献

The recent proliferation of bitcoin has been a boon for users but might pose problems for governments. Indeed, some governments have already taken steps to ban or discourage the use of bitcoin. In a model with endogenous matching and random consumption preferences, we find multiple monetary equilibria including one in which bitcoin coexists with official currency. We then identify the conditions under which government transactions policy might deter the use of bitcoin. We show that such a policy becomes more difficult if some users strictly prefer bitcoin because they can avoid other users holding the official currency in the matching process.

How did Frenchmen profiting from colonial slavery respond to the emergent discourse of human rights? Le commerce de l'Amérique par Marseille (1764), a trade manual by Auguste Chambon, provides exceptional insight into the moral imagination of eighteenth-century commercial capitalists. Chambon encouraged the French to pursue slaving more aggressively. Yet rather than deny the problem of slavery, he questioned openly whether slavery violated morality, religion, and natural rights, responding to Montesquieu, Rousseau and Voltaire from a rare Catholic-inspired perspective. Lamenting slavery as a ‘cruel necessity’ for France, Chambon enabled merchants to represent themselves as sympathetic and patriotic while preserving profits.  相似文献

Prior to 2002, little was known about sexual abuse within the Catholic Church. After the Boston Globe broke the story about John Geoghan - a priest in the Boston Archdiocese who was accused of abusing numerous children, convicted of one count of indecent assault, and eventually murdered in prison - the Church had many questions to answer. To this end, the United States Conference of Catholic Bishops (USCCB) commissioned John Jay College of Criminal Justice to research the nature and scope, as well as the causes and context of child sexual abuse within the Catholic Church.This research analyzes the data from the John Jay studies using a new quantitative technique, capable of adjusting for distortions introduced by delays in abuse reporting. By isolating discontinuities in model parameter timeseries, we determine changes in reporting patterns occurred during the period 1982-1988. A posteriori to the analysis, we provide some possible explanations for the changes in abuse reporting associated with the change-point. While the scope of this paper is limited to presenting a new methodological approach within the frame of a particular case study, the techniques are more broadly applicable in settings where reporting lag is manifested.  相似文献

Concerns about decreasing response rates have led to many nonresponse studies. Unfortunately, usually only a limited amount of data is available on nonrespondents. Linking administrative data makes information available on all the sampled units including nonrespondents. Statistics Netherlands has constructed a database in which several administrative records and several surveys are connected. In this explorative study we use this dataset to look for homogenous groups of respondents and nonrespondents in survey research using latent class cluster analysis. Latent class techniques can provide insight into the problem of selective nonresponse and currently under-represented societal groups. We identify four different latent classes in a recent Dutch survey and replicate the findings for the same survey conducted 4 years later. Two of the types of sampled units have above-average response rates and the other two have below-average response rates. We also evaluate various latent class models with other response outcomes to gain insight into the contact and cooperation process.  相似文献

Every social science researcher must make a number of methodological decisions when planning and implementing research projects. Each such decision carries with it both advantages and limitations. The decisions faced and made by Regnerus (2012) are discussed here in the wider context of social science literature regarding same-sex parenting. Even though the apparent outcomes of Regnerus’s study were unpopular, the methodological decisions he made in the design and implementation of the New Family Structures Survey were not uncommon among social scientists, including many progressive, gay and lesbian scholars. These decisions and the research they produced deserve considerable and continued discussion, but criticisms of the underlying ethics and professionalism are misplaced because nearly every methodological decision that was made has ample precedents in research published by many other credible and distinguished scholars.  相似文献
