Latane and Darley developed a five-stage model to understand why people do and do not help other people in emergency situations. We extend their five-stage model to explore why people do and do not take action against climate change. We identify the factors that make climate change difficult to notice and ambiguous as an emergency; we explore barriers to taking responsibility for action; and we discuss the issues of efficacy and costs versus benefits that make action unlikely. The resulting analysis is useful on two levels. For educators and policy makers, the model suggests the most efficacious approaches to galvanizing action among U.S. citizens. For social scientists, the model provides a valuable framework for integrating research from diverse areas of psychology and suggests fruitful avenues for future empirical research. 相似文献

This is an evaluative study on the delivery of devolved programs in health, agriculture and social welfare. It aimed to identify the major devolved programs/projects implemented by the LGU of Columbio, Sultan Kudarat; the responsiveness of the actual delivery of devolve services in terms of human resources, facilities and fund allocation; the status of devolve services implemented if it was effective and efficient; and the inadequacies encountered. The “expose facto” method of research was used. There were 49 implementers and 132 beneficiaries of the various devolved programs. There were 181 total respondents. A four-part questionnaire was constructed and the gathered data were supplemented by information extracted through interviews with Key Informants, Focus Group Discussions and document analysis. There were three departments implementing the devolved social services programs such as the Municipal Health Office with 6 devolved health programs; the Municipal Agriculturist Office with 6 devolved agricultural projects; and the Municipal Social Welfare and Development Office with 7 devolved social welfare programs. The respondents rated the implementation of devolve services in health, agriculture and social welfare programs between rank 5 to 9 for the aspects of human resources, facilities and fund allocations. The respondents assessed the implementation of devolved programs as Very Efficient and Most Responsive programs to the needs of the people specially the children, youths and women. The study also found some inadequacies observed during the implementation of devolved social services programs which were Agreed by the majority of the respondents. These findings implied that the implementation of various devolved social services for several years has made a significant difference in the lives of the people of the Municipality of Columbio, Sultan Kudarat, the Local Government of Columbio and program implementers with their commitment and solidarity to serve the people especially the marginalized is a manifestation of their unselfish dedication to uplift the socio-economic condition and well-being of the people. Hence, continuing projects should further be strengthened and supported to ensure the sustainability of the projects even if the support of different institutions has been terminated. 相似文献

This study utilized data from the National Survey of American Life to investigate the use of professional services and informal support among African American and Caribbean black men with a lifetime mood, anxiety, or substance use disorder. Thirty-three percent used both professional services and informal support, 14% relied on professional services only, 24% used informal support only, and 29% did not seek help. African American men were more likely than to rely on informal support alone. Having co-occurring mental and substance disorders, experiencing an episode in the past 12 months, and having more people in the informal network increased the likelihood of using professional services and informal supports. Marital status, age, and socioeconomic status were also significantly related to help-seeking. The results suggests potential unmet need. However, the reliance on informal support also suggests a strong protective role that informal networks play in the lives of black men. 相似文献

Bistrategic resource control entails using both coercive and prosocial strategies in competition for resources. The present study sought to clarify whether bistrategic involves more than simply using both strategies some of the time. Examining 88 preschoolers' coercion and prosociality over an entire school year, results showed that coercive resource control was used most frequently at the start of the school year, presumably to access resources and establish social dominance. Rates of prosocial resource control increased over the school year, and socially dominant preschoolers showed higher rates compared with peers, presumably to maintain resource control while keeping peers as allies. Socially dominant preschoolers also used reconciliation more often than peers, resulting in higher rates of affiliation between former competitors and more positive peer regard from fall to spring. Findings are discussed in terms of resource control theory and the importance of situating social behaviors within the behavioral and relationship context in which they are embedded. 相似文献

Objective. Research on widespread loan failures suggests that many of the mortgage loans that were made since 2000 were of a deceptive or predatory nature. This study explores the experiences and sentiments of those who are at risk of foreclosure within a broader framework of trust, individualization, and ontological security. Methods. Interviews examine families' lending experience and how they have coped with their personal troubles that resulted from their housing crisis. Results. As many of these loans were of a deceptive or predatory nature, individuals are likely to reflect on the psychological consequences of their predicament. Although these findings suggest that these individuals have lost trust in the housing market, many have internalized their situation as a personal failure. In addition, feelings of anxiety, stress, insecurity, and uncertainty have come to characterize their experiences. Conclusions. This research calls for policy recommendations that seek to restore confidence and to ensure greater consumer protection in financial markets. 相似文献

This study reports preliminary findings regarding the feasibility and efficacy of a novel couple-based treatment, named Strategic Approach Therapy (SAT), for reducing avoidance symptoms of posttraumatic stress disorder (PTSD). Six male Vietnam combat veterans diagnosed with PTSD and their cohabitating marital partners participated in 10 weeks of SAT treatment. Self-report, clinician ratings, and partner ratings of PTSD symptoms were obtained before the first session and after the tenth session of treatment. Veterans reported statistically significant reductions in self-reported, clinician-rated, and partner-rated effortful avoidance, emotional numbing, and overall PTSD severity. These data indicate that SAT offers promise as an effective treatment for PTSD avoidance symptoms. 相似文献

We examined factors underlying people's willingness to take action in favor of or against nuclear energy from a moral perspective. We conducted a questionnaire study among a sample of the Dutch population (N = 123). As expected, perceptions of risks and benefits were related to personal norms (PN), that is, feelings of moral obligation toward taking action in favor of or against nuclear energy. In turn, PN predicted willingness to take action. Furthermore, PN mediated the relationships between perceptions of risk and benefits and willingness to take action. In line with our hypothesis, beliefs about the risks and benefits of nuclear energy were less powerful in explaining PN for supporters compared to PN of opponents. Also, beliefs on risks and benefits and PN explained significantly more variance in willingness to take action of opponents than of supporters. Our results suggest that a moral framework is useful to explain willingness to take action in favor of and against nuclear energy, and that people are more likely to protest in favor of or against nuclear energy when PN are strong. 相似文献

A positive relationship between FDI and economic growth under two economic conditions has been estimated: a sufficient level of human capital and well-developed financial markets, respectively. However, these two conditions can be fundamentally different catalysts for FDI to promote economic growth in the perspective of growth accounting. Using data from 69 countries over 1970–1989, we find that FDI promotes productivity growth only when the host country reaches a threshold level of human capital; and FDI promotes capital growth only when a certain level of financial development is achieved.
