Ephemeral social media, platforms that display shared content for a limited period of time, have become a prominent component of the social ecosystem. We draw on experience sampling data collected over two weeks (Study 1; N?=?154) and in-depth interview data from a subsample of participants (Study 2; N?=?28) to understand college students’ social and emotional experiences on Snapchat, a popular ephemeral mobile platform. Our quantitative data demonstrated that Snapchat interactions were perceived as more enjoyable – and associated with more positive mood – than other communication technologies. However, Snapchat interactions were also associated with lower social support than other channels. Our qualitative data highlighted aspects of Snapchat use that may facilitate positive affect (but not social support), including sharing mundane experiences with close ties and reduced self-presentational concerns. In addition, users compared Snapchat to face-to-face interaction and reported attending to Snapchat content more closely than archived content, which may contribute to increased emotional rewards. Overall, participants did not see the application as a platform for sharing or viewing photos; rather, Snapchat was viewed as a lightweight channel for sharing spontaneous experiences with trusted ties. Together, these studies contribute to our evolving understanding of ephemeral social media and their role in social relationships. 相似文献

This is the second essay in a two‐part series exploring the relationships between mental illness, criminal behavior, and the criminal justice system. The number of mentally ill persons in prisons and jails has increased substantially over the last several decades, and there are currently more people with mental illness behind bars than there are in mental hospitals. In this essay, we place these trends within a broader historical context of the social control of mental illness in the United States. We identify how and why mentally ill persons have come to be overrepresented in the criminal justice system and highlight the unique challenges this population poses for police, courts, and correctional facilities. Finally, we review several recent innovations in policy and practice that may help alleviate that burden of criminal justice involvement on mentally ill offenders, as well as the burden of mentally ill offenders on the criminal justice system. 相似文献

The current study examined hooking up experiences through event-level analyses, including the connections involving alcohol use, the extent of physical contact, and postevaluations of the hookup event. Participants were 828 college students (67.0% female). Of students who reported hooking up sometime within the past year (54.8%), chi-square analyses revealed that they were more likely to have been drinking when they met their partners the night of the hookup. Females who were drinking beforehand and females who met their partners that night were more likely to feel discontent with their hookup decisions. Among participants who consumed alcohol prior to their last hookup, a notable 30.7% of females and 27.9% of males indicated that they would likely not have hooked up with their partners had alcohol not been involved. Further, 34.4% of females and 27.9% of males indicated that they would not have gone as far physically if they had not been drinking. Among participants who reported both drinking beforehand and hooking up with unfamiliar partners, greater number of drinks consumed was associated with more advanced sexual behaviors. The current findings highlight the potential risks associated with alcohol use in the hooking up culture. 相似文献

We interpret three strands of social movement theory (social threat, opportunity structure, and resource mobilization) to understand religious congregations' political activity related to same‐sex marriage. Using a unique, national data set from the 2008 presidential election, we show the importance of the anti‐same‐sex marriage discursive opportunity structure (DOS) for facilitating, and occasionally constraining, congregational political activity. Other theoretical factors influence congregations under limited, although important, conditions. Our research develops a nuanced understanding of congregations' roles in social movements that prioritize institutionalized political activity and expands DOS theory in relation to local religious organizations. 相似文献

Social transformations in Brazil in recent years have included a substantial increase in adolescent fertility, a dramatic rise in membership of Protestant religious denominations, and an accompanying decline in the number of Catholics. We used the 2000 Brazil Census to examine differentials in fertility and family formation among adolescents living in Rio de Janeiro by the following religious denominations: Catholic; Baptist; other mainline Protestant; Assembly of God Church; Universal Church of the Kingdom of God; other Pentecostal Protestant; and no religion. Results from logistic regression models show that the majority of the Protestants are at a lower risk of adolescent fertility than Catholics, and that among adolescents who have had a child, most Protestants are more likely than Catholics to be in a committed union. Our findings offer some support for the hypothesis that Protestant churches are more effective than the Catholic Church in discouraging premarital sexual relations and childbearing among adolescents. 相似文献

While reducing out-of-wedlock childbearing is a central goal of welfare reform, most policymakers prefer achieving this objective
via a reduction in nonmarital pregnancy rates rather than through an increase in the incidence of abortion. Using aggregate
state-level data from 1984 to 1998, I estimate fixed effects models that allow for autocorrelated and heteroskedastic disturbances
to examine the association between the family cap and nonmarital birth, pregnancy, and abortion rates. I find robust evidence
that the family cap is associated with a reduction in nonmarital birth rates, particularly among black women. This reduction
is driven by a reduction in nonmarital pregnancy rates rather than through an increase in abortion or marriage rates. These
findings suggest that that the stigmatizing effect of the family cap may influence the nonmarital pregnancy decisions of black
women.

We use census data to investigate fertility change across more than 500 Brazilian microregions during 1970–2000, before and
after controlling for local covariates. We use semivariograms to analyze spatial patterns, in order to investigate the importance
of diffusion or social interaction in the spread of fertility transition across a map. Our analysis shows that spatial patterns
in Brazilian fertility change are strongly related to spatial patterns in measurable local conditions such as electrification,
child mortality, and female education. Differences in local conditions are particularly good at explaining spatial correlations
at distances >500 km. At shorter distances, there remains some unexplained spatial correlation in fertility change that could
be attributed to diffusion or social interaction. 相似文献

Asian Americans are the most highly educated racial group in the United States and are commonly heralded as the model minority for their high academic success. Nevertheless, previous research suggests that Asian Americans may face certain disadvantages in school settings. For example, Asian Americans’ academic advantage over non-Hispanic white students diminishes between kindergarten entry and the next several years of schooling. This study provides a closer examination of the educational progress of Asian American students compared to white students through a seasonal comparison approach. Using the Northwest Evaluation Association, we analyze reading and math scores for over 130,000 Asian American and white students in grades K-7 in approximately 675 public schools across the US. We find that Asian Americans have higher academic achievement than white students in general, but that these advantages are maintained primarily through faster rates of learning during the summer months. When school is in session, the Asian advantage either remains unchanged or shrinks, consistent with the view that some school processes undermine the educational progress of Asian American students relative to white students. 相似文献

The presence of block effects makes the optimal selection of fractional factorial designs a difficult task. The existing frequentist methods try to combine treatment and block wordlength patterns and apply minimum aberration criterion to find the optimal design. However, ambiguities exist in combining the two wordlength patterns and therefore, the optimality of such designs can be challenged. Here we propose a Bayesian approach to overcome this problem. The main technique is to postulate a model and a prior distribution to satisfy the common assumptions in blocking and then, to develop an optimal design criterion for the efficient estimation of treatment effects. We apply our method to develop regular, nonregular, and mixed-level blocked designs. Several examples are presented to illustrate the advantages of the proposed method. 相似文献
