In the last few years, apps have become an important tool to collect data. Especially in the case of data on people’s happiness, two projects have received substantial attention from both the media and the scientific world: “Track your happiness” from Killingsworth and Gilbert (Science, 330, 932-932, 2010), and “Mappiness,” from MacKerron (2012). Both happiness apps used the experience sampling method to ask people a few times per day how they feel, what they do, with whom, and where. The collected data are then displayed for the participants in simple graphs to help them understand what makes them happy and what does not. Both studies have collected considerable data without giving participants any financial rewards. But quantity is not everything that matters with respect to data collection, and thus, understanding whether nationally representative datasets can be collected using such happiness apps is crucial. To address this question, we built a new happiness app and ran a case-study with over 4000 participants of the innovation sample of the German Socio-Economic Panel (Richter and Schupp in Schmollers Jahrbuch, 135(3), 389–399, 2015). Participants were informed that the app collects data on everyday happiness after a household interview and asked whether they would like to use the app. In the first year (2015), participants did not receive any reward, and in the second year (2016), a different group of participants received a 50 Euro Amazon voucher for their participation. The results showed that our happiness app cannot generate nationally representative datasets if it is not controlled that all demographic sub-groups have access to a smartphone, are highly motivated with a sufficient reward and data is collected with quota sampling.

Social scientists have long been interested in the study of grief and bereavement, but only recently has research focused on the aftereffects of sudden loss. Theory and research alike suggest that grief is multidimensional and that specific grief reactions have a unique set of predictors. The purpose of this study is to examine the relative contribution of risk factors in explaining variations in specific grief reactions following a sudden death. Data for this study come from medical examiners' reports and mail-back surveys of survivors of sudden loss from suicide or accident. The results indicate that several characteristics of the survivor, mode of death, and social support are important determinants of grief symptomatology. This research concludes by directing future theoretical and empirical endeavors to examine more fully the role of relational factors in influencing grief experiences following bereavement.  相似文献

Women's sexual health is directly affected by women's low status in society. This low status, and subsequent lack of sexual autonomy, not only increases risk for sexual health problems, it also decreases ability to obtain treatment and support when a sexual health concern arises. This has clearly been demonstrated in the HIV epidemic within the U.S.. Earlier in the epidemic, women were simply ignored by public health research and practice. Once they could no longer be ignored, they were blamed and viewed as vectors. Current seroprevalence rates among men reveal that women are not significant vectors. In contrast, rates among women indicate that infection from men is the primary mechanism by which women are contracting HIV, and male-controlled sexual decision-making, male partner violence against women, and histories of sexual assault all contribute to increased HIV risk for women. Once infected, women are not given the support and resources they need as mothers and caretakers of HIV-positive partners and/or children. These findings are especially true for marginalized women such as women of color, poor women, women addicted to alcohol or drugs, and women who exchange sex for drugs or money. Findings from this review demonstrate the need for feminist approaches in understanding and addressing this issue in the Decade of Behavior. Such approaches must include an understanding of the needs of diverse women. An empowerment approach is needed to better contend with the sexual health needs of women; this must include the goal of ensuring women's control of their own bodies.  相似文献

In this article I argue that vanity, the desire for and delight in the favorable opinion of others, plays a fundamental role in Hume's account of moral motivation. Hume says that vanity and virtue are inseparable, though he does not explicitly say how or why this should be. I argue that Hume's account of sympathy can explain this alliance. In resting moral sentiment on sympathy, Hume gives a fundamental role to vanity as it becomes either a mediating motive to virtue or else strengthens the otherwise weak motive of moral sentiment.  相似文献

This study examined whether the type of prompt or the method of passage reading had an effect on the retell performance of 6th–8th graders randomly assigned to one of four retell testing conditions. Both the type of prompt and the use of follow-up prompting were significantly related to the percentage of predetermined idea units retold. Effect sizes were approximately moderate (d = .44–.62) when one change was made to the prompt but were strong (d = .96–1.05) with a combination of changes. The addition of silent reading did not significantly improve performance.  相似文献
