We hypothesized that people who can better disclose their "true" or inner self to others on the Internet than in face-to-face settings will be more likely to form close relationships on-line and will tend to bring those virtual relationships into their "real" lives. Study 1, a survey of randomly selected Internet newsgroup posters, showed that those who better express their true self over the Internet were more likely than others to have formed close on-line relationships and moved these friendships to a face-to-face basis. Study 2 revealed that the majority of these close Internet relationships were still intact 2 years later. Finally, a laboratory experiment found that undergraduates liked each other more following an Internet compared to a face-to-face initial meeting. 相似文献

Objective. This study examines the backgrounds, political attitudes, issue preferences, and political participation of congressional donors who contribute $200 or more to congressional campaigns. Methods. We use a nationwide survey of more than 1,000 donors and analyze differences among these individuals using cluster analysis. Results. Although these significant donors are economic elites, we find they are not monolithic in their political views and attitudes. There are significant cleavages in the donor pool across and within the two major parties on various political issues and involvement in different political organizations. Perhaps most important, we find that the most active donors hold the most ideologically extreme political views. Conclusions. The results suggest that the sharp cross‐party differences and the meaningful variations within party coalitions, combined with the greater activity of more ideologically extreme donors, contribute to and reflect party polarization. 相似文献

In most commercial applications of k-means clustering, researchers choose one set of kseed points to start the partitioning process; often, the initial set of seeds is chosen randomly. Using Monte Carlo simulation, we show that significant benefits are associated with replicated starting configurations that incorporate seed selection procedures based on a hierarchical clustering of sample points drawn from the original data matrix. A real-world application of the approach is then presented. 相似文献

Tweddle's Parenting Assessment and Skill Development Service (PASDS) is a 10-day residential programme for families at risk of child maltreatment. The service aims to conduct a comprehensive parenting capacity assessment to inform case management and improve parenting practices. The aims of the study were to (1) describe the psychosocial functioning of parents taking part in PASDS, (2) describe the key parenting assessment outcomes, and (3) explore parents' experiences of participation in PASDS including (a) perceived barriers and enablers of participation and (b) perceived outcomes for their family. Participants were 18 parents who participated in Tweddle's PASDS in Melbourne, Australia. A mixed methods study comprising a case file review and qualitative interviews was conducted. Parents accessing PASDS had experienced adverse childhood events, and many were experiencing mental health difficulties. Interviews with parents revealed perceived benefits of PASDS in improving parenting knowledge and skills, family relationships, and parenting confidence. At the time of discharge, 33% of families were assessed as unable to provide independent care for their child. The current findings have important implications for the further evaluation of evidenced-based services which can improve the accuracy of parenting capacity assessments, aiding in child protection decision-making related to child placement and safety. 相似文献

Socioeconomic vulnerabilities put adolescents at risk for mental wellbeing issues, also in times of a pandemic. In the present longitudinal online survey study, we explored changes in mental wellbeing (i.e., mood and life satisfaction) during the COVID-19 pandemic. Second, we examined how socioeconomic hardship in online home schooling predicted adolescents’ mental wellbeing 1 year later. Third, we tested whether this relation was mediated by feelings of uncertainty about the future. Fourth, we tested whether this relation was moderated (in terms of a protective factor) by self-efficacy. In total, 177 Dutch-speaking adolescents aged 10–18 years (Mage = 15.64, SDage = 1.72, 79% females) participated in all three 6-month separated waves (T1 = May 2020, T2 = November 2020, and T3 = May 2021). Mood results demonstrated that feelings of vigor decreased between T1 and T2, and feelings of tension and depression increased between T1, T2, and T3. Socioeconomic hardship in online home schooling in the early phase of the pandemic was negatively associated with both baseline mental wellbeing and 1 year later. Socioeconomic hardship at T1 predicted higher feelings of future uncertainty at T2, and higher levels of future uncertainty were associated with lower feelings of vigor, and higher feelings of tension and depression at T3. However, we found no evidence for mediation or moderation effects. In conclusion, the present findings illustrate the complexity of disentangling the adverse effects of socioeconomic hardship on adolescent mental wellbeing. 相似文献
