Despite growing interest in end-of-life issues, little research has been done concerning end-of-life plans made by patients with cardiovascular disease (CVD), a disease that constitutes the highest mortality in the United States. Even less information is available on patients who undergo major cardiac surgery, a life-altering procedure with some risk of death, in terms of their engagement in end-of-life planning (EOLP). This prospective study enabled the contributors to explore EOLP among 309 middle-aged and older open-heart surgery patients, using survey data from three sequential interviews. A hierarchical logistic regression model shows that older age, higher education, greater social support, and negative religious coping were positively related to the likelihood of engaging in EOLP. Minority race was inversely related to EOLP. Findings suggest the potential role for social workers in helping cardiac patients to access social spiritual resources, and to consider engagement in EOLP.  相似文献

The Future of Nuclear Power: Value Orientations and Risk Perception   总被引:1,自引:0,他引:1  
Since the turn of the 21st century, there has been a revival of interest in nuclear power. Two decades ago, the expansion of nuclear power in the United States was halted by widespread public opposition as well as rising costs and less than projected increases in demand for electricity. Can the renewed enthusiasm for nuclear power overcome its history of public resistance that has persisted for decades? We propose that attitudes toward nuclear power are a function of perceived risk, and that both attitudes and risk perceptions are a function of values, beliefs, and trust in the institutions that influence nuclear policy. Applying structural equation models to data from a U.S. national survey, we find that increased trust in the nuclear governance institutions reduces perceived risk of nuclear power and together higher trust and lower risk perceptions predict positive attitudes toward nuclear power. Trust in environmental institutions and perceived risks from global environmental problems do not predict attitudes toward nuclear power. Values do predict attitudes: individuals with traditional values have greater support for, while those with altruistic values have greater opposition to, nuclear power. Nuclear attitudes do not vary by gender, age, education, income, or political orientation, though nonwhites are more supportive than whites. These findings are consistent with, and provide an explanation for, a long series of public opinion polls showing public ambivalence toward nuclear power that persists even in the face of renewed interest for nuclear power in policy circles.  相似文献

This study investigated differences in depressive symptoms, loneliness, and self-esteem for monosexual (lesbian, gay) and plurisexual (bisexual, pansexual, queer) sexual minority youth (SMY) by relationship status (single, partnered) and relationship configuration (same-gender partner, different-gender partner). Participants included 338 SMY (Mage = 19.10 years) who reported on their relationship status, partner's gender identity, well-being, and ability to confide in partner about LGBTQ issues. Results indicated that for plurisexual youth, single status was associated with greater loneliness; plurisexual youth with same-gender partners reported fewer depressive symptoms and marginally greater ability to confide in their partner about LGBTQ issues than those with different-gender partners. Findings reveal similarities across SMY while also highlighting some unique challenges among plurisexual youth with different-gender partners.  相似文献

This paper demonstrates how qualitative analysis can be a novel means of investigating theories of error and causation in natural gas pipeline incidents. Qualitative analysis offers unique opportunities to understand process, interactions, and the role of context in identifying active error and latent conditions in incident causation. Through the coding of text from 24 onshore natural gas pipeline incident reports on leaks and explosions in the United States and Canada, our findings reveal a proportion of active and latent errors consistent with other hazardous infrastructure contexts (roughly 3:1 latent-active ratio across 817 coded errors). These findings underscore the robustness of extant error theory and support the argument for documenting multiple, connected causes of disaster in aggregate. Conclusions highlight the utility of in-depth case analyses and critique present pipeline incident database aggregation. Our interpretation provides a means to convey complex causation in aggregate form thus enabling more nuanced future qualitative and qualitative analyses.  相似文献

Culture provides a context in which emotion socialization is embedded, and the bidirectional effects between parents’ emotion socialization and children's emotional behaviors may work differently across cultures. To understand how emotion socialization may be shaped by the cultural context, we examined the moderating role of Asian cultural values in bidirectional associations between maternal emotion socialization practices and child anger and sadness. Seventy-four U.S. Chinese immigrant mothers (Mage = 40.71 years, SD = 3.61) completed measures assessing their Asian cultural values and parenting style. Children experienced a disappointment task in the lab (Cole, 1986), and mothers and their children (Mage = 6.73 years, SD = .95; 55% female) were observed at two different time intervals. Mothers’ socialization practices (emotion dismissing, emotion coaching, and moral and behavioral socialization) and children's anger and sadness responses at both intervals were coded. Mothers’ greater Asian cultural values buffered the negative effects of their emotion dismissing practices on children's anger and sadness. However, Asian cultural values did not impact the effects of children's anger and sadness on mothers’ emotion dismissing practices. When mothers endorsed fewer Asian values, their emotion coaching practices reduced children's anger and sadness. Children's anger and sadness evoked more emotion coaching practices when mothers endorsed lower levels of Asian cultural values. In addition, children's anger and sadness evoked greater moral and behavioral responses from their mothers when mothers endorsed more Asian values. Overall, findings underscored the importance of cultural values in the interplay between mothers’ emotion socialization practices and children's emotions.  相似文献

In a study of conflict recovery and adolescent dating aggression, 14- to 18-year-old couples (N = 209 dyads) participated in a 1-hr observational assessment. Negative behavior was observed during conflict-evoking “hot” tasks and in a “cooldown” task. Physical and psychological dating aggression were assessed via questionnaires. Negative behavior measured in the cooldown task was not associated with dating aggression after controlling for carryover effects of negativity from the hot to cooldown tasks. Moreover, cooldown negativity moderated the associations of hot task negativity and dating aggression. Actor and partner effects were disentangled via dyadic data analyses. Given the paucity of observational studies of dating aggression, our findings are an important contribution to the literature and in need of replication and extension.  相似文献

Early childbirth is common among young women ageing out of foster care and may impede their educational progress. However, few studies have explored access to postsecondary education among young mothers who have been in foster care. The present study used data from a large, national sample of young people in foster care (National Youth in Transition Database, NYTD) to examine the link between early childbirth and young women's access to postsecondary education between ages 19 and 21, controlling for an array of covariates. The study sample included 2,207 young women who had completed a high school diploma or GED by age 19 and who participated in three NYTD interviews at ages 17, 19 and 21. Childbirth between ages 19 and 21 was linked to decreased access to postsecondary education. However, no relationship was found between access to postsecondary education and childbirth by age 17 or childbirth between ages 17 and 19. Implications for policy, practice and research are discussed.  相似文献

Using a normative US sample of 477 mothers of 6- to 24- month-old children, we explored the relations among toddlers’ physical aggression, child temper loss, and parent-child conflict to gain a better understanding of how aggression develops from infancy to toddlerhood. An inventory of specific aggressive acts was subject to factor analysis to test whether the acts clustered as hypothesized. Consistent with our hypothesis, confirmatory factor analyses supported the distinction between the two types of aggression, directed and exploratory physical aggression. Although the two types were correlated, they showed differential associations with temper loss and parent-child conflict consistent with theory. Directed aggression had a relatively stronger relation with child defiance and temper loss than did exploratory aggression. Moreover, the association between directed aggression and defiance was stronger for older children. The findings from this cross-sectional study provide preliminary support for two forms of early aggression that may differ in trajectory and context.  相似文献
