Religiosity and Financial Crises in the United States

The farm crisis in the United States in the 1980s had profound effects on rural, agricultural regions of the country, but almost no impact on urban and suburban areas. At the same time, the 2007–2008 housing crisis impacted almost all metropolitan areas, but was much more deeply felt in certain states, such as California, Arizona, Nevada, and Florida. I use a difference‐in‐differences methodology and find that religiosity as measured by religious attendance, prayer frequency, and religious intensity increased significantly in areas impacted by the farm crisis for those who worked in agriculture, and by the housing crisis for those who worked in housing‐related industries. Chen describes increased religiosity in Indonesia following the 1998 financial crisis, and this article demonstrates a similar response to severe financial distress in the United States. This increase is not due to a lower opportunity cost of time, as those who are currently employed have higher levels of attendance than those who are not. I hypothesize that the increased religiosity results from religious institutions’ ability to provide public goods, both financial and emotional, in the form of community support.     

Managing financial conflicts of interest in clinical research

Upholding public trust in clinical research necessitates that human subjects be protected from avoidable harm and that the design, interpretation and reporting of research results be shielded from avoidable bias. On both counts, managing financial conflicts of interest is critically important, especially in the modern era when the opportunities for investigators to benefit personally from the commercialization of their intellectual property are overtly encouraged and rapidly expanding. Efforts are underway in the United States to provide more useful guidance to universities and medical schools for purposes of strengthening the oversight and management of financial conflicts of interest in clinical research. An earlier version of this paper was presented at an International Conference on “Conflict of Interest and its Significance in Science and Medicine” held in Warsaw, Poland on 5–6 April, 2002.     

The effect of perceived financial vulnerability on prosocial activity

Our research examines the effect of subjective financial vulnerability on prosocial activity. First, data from the European Survey of Health, Aging and Retirement (SHARE) revealed that higher assessment of one's financial vulnerability might be associated with prosocial motivation for social activities. Next, we manipulated participants' perception of their relative financial position compared to their peers and found that participants randomly assigned to the low financial position condition were more willing to volunteer than participants assigned to the high financial position condition. In Study 3, we manipulated participants' financial advantage. Participants who were disadvantaged in the experimental settings were more willing to volunteer and donate to charity compared to participants with financial advantage. In our final study, we examined willingness to donate to in‐group and out‐group help organizations and found that individuals of lower perceived financial standing may be motivated by the goal of increasing the strength of the social group, rather than by expectations of direct reciprocity. We also found that emotional distress mediates the relationship between perceived financial vulnerability and prosocial behavior. In line with earlier research illustrating that lower financial status promotes prosociality on an interpersonal level, we demonstrate that even momentary perception of relative financial disadvantage and vulnerability promotes prosociality in the broader social context.     

If giving money to the Red Cross increases well-being,does taking money from the Red Cross increase ill-being? – Evidence from three experiments

Does having a negative impact on others decrease one’s well-being? In three separate pre-registered studies (n = 111, n = 445, & n = 447), participants engaged in a button-pushing activity for 4 min in three conditions: earning money for themselves (~60c), also earning money for the Red Cross (~15c), or also reducing the money distributed to the Red Cross (~15c). The results of the individual studies and a meta-analysis across them showed that positive impact increased well-being, but even though participants were aware of the negative impact they were having, there was no increased ill-being in the negative impact condition. In Study 3 we examined whether participants in the negative impact condition are mentally compensating by emphasizing the positive impact they are having towards science.     

Understanding subgroup differences with general mental ability tests in employment selection: Exploring socio-cultural factors across inter-generational groups

In employment selection, general mental ability (GMA) tests predict training and job performance but also lead to subgroup differences which in turn can produce adverse impact against minority groups. Although researchers have explored genetic, developmental, and environmental explanations for ethnic group differences, few studies have explored socio-cultural factors comparing immigrant and non-immigrant job applicants. Given that many ethnic job applicants may also be immigrants, understanding these factors can provide insight into GMA test score differences. The purpose of this paper is to explore the impact of individual and socio-cultural factors on GMA test scores with immigrant and non-immigrant bus driver applicants. This is the first study of its kind to our knowledge that has attempted to disentangle the effects of socio-cultural factors from race/ethnicity in the study of subgroup differences. Incorporating these variables between non-visible minority and minority groups accounted for considerable variance in GMA test scores across groups. The implications of focusing on socio-cultural variables to enhance our understanding of subgroup differences are discussed. Our results specifically suggest that practitioners attend to the issue of the intersecting grounds of potential discrimination when using GMA tests in personnel selection.     

Necessity (not just novelty) is the mother of invention: using creativity research to improve research in work and organizational psychology

In this essay, we discuss reasons that work and organizational psychology does not live up to its self-declared mission of being an applied science in the service of improving both people’s quality of working life and organizational effectiveness. We use fundamentals of research on creativity and innovation as a lens through which we can view problems and possible solutions to these problems. In particular, we stress that innovation entails not only new, but also useful insights, that innovation requires “rewarding failure”, and that innovation feeds off of team diversity. We provide suggestions for how the definition of theoretical and empirical contributions of research, reward systems, and collaboration practices could be changed to foster innovative research that helps people thrive at work.     

Ethics in banking,corporate maturity and faith

It is difficult to understate the impact of the 2008 Global Financial Crisis on entire economies, local communities, families and individuals. The Crisis, and what has followed, provides a window into the behaviour of large corporations and the assumptions underpinning corporate life more generally. This raises issues for the Christian Church and for all faiths seeking a more collective view of our common good and a shared journey. This article evaluates the extent to which anything has been learned since 2008, both within financial services and more widely, and presents ways in which a focus on faith, ethics, culture and community outcomes can be brought to the fore and embedded in businesses and organisations to achieve a longer-term maturity.     

Increasing toughness by promoting discontinuous precipitation in Cu–Ni–Si alloys

The influence of precipitation morphology, including continuous precipitation (CP) and discontinuous precipitation (DP), on the mechanical behaviour of Cu–Ni–Si alloys was studied. The Cu–6Ni–1.5Si (in wt%) alloy was solution heat treated at 980 °C for 2 h and aged at 500 °C for 0.5 and 3 h to produce CP and DP structures. The DP specimen showed an abnormal increase in tensile ductility with increasing strain rate, unlike the CP counterpart. The impact toughness of the DP specimen was 1.6 times greater than that of CP specimen. The fracture mode in DP specimen was mostly dimpled rupture, while the mixed mode of cleavage fracture and dimpled rupture was noted on the CP specimen.     

幼儿园教师的心理健康:对基于SCL-90量表研究的元分析

症状自评量表(SCL-90)在过去15年里广泛用于幼儿园教师心理健康状况调查,然而调查结论却很不一致。为了综合这些相互矛盾的调查结果,分析其原因,37项原始研究(含42个独立样本)进入了元分析。结果显示:(1)幼儿园教师的SCL-90得分与常模没有显著差别,明显低于中小学教师;(2)城镇教师和农村教师、公办教师与民办教师的得分可能有差异;(3)离婚率、教育经费投入,以及出生死亡率与幼儿园教师的SCL-90得分有显著相关。幼儿园教师在心理健康积极端的表现,以及压力–资源–心理健康之间的因果关系在未来研究中需要更多关注。
