Canada continues to be a prominent immigrant and refugee‐receiving country in worldwide migration, resettlement, and search for refuge, yet there is a gap in our understanding of these newcomers’ views of the specific meanings of social support and their support needs and resources. The purpose of this study was to understand the meanings of social support for immigrants and refugees in Canada, and to explore the types and adequacy of formal supports. Individual interviews were conducted with 60 service providers and policymakers initially (Phase 1), and 120 immigrants and refugees (60 Chinese, 60 Somali) in the second phase. The implications of these findings were elicited in group interviews (Phase 3) of policy decision‐makers, advocates, service providers, and managers. This investigation revealed many interrelated challenges facing refugees and immigrants such as language difficulties, inadequate information on services, poor health, racism, needs for retraining, rejection of foreign qualifications, unemployment, social isolation, social insecurity, dwindling social networks, and family conflicts. The study also illuminated culturally and socio‐economically determined perceptions of social support and support‐seeking strategies. Limited personal resources and dwindling social networks are an impediment to coping with integration and settlement challenges. In many cases, newcomers’ efforts to seek help are thwarted by systemic obstacles. Newcomers experienced extensive unmet support needs, which service providers cannot adequately meet due to bureaucratic and resource constraints. Policies in various sectors that affect the lives of immigrants and refugees are inadequate for bridging their support deficiencies. These support gaps hinder the successful settlement and integration of newcomers. Policies and programs fostering culturally relevant support, and inter‐sectoral collaboration among organizations addressing the support needs of immigrants and refugees are timely. 相似文献

We examined the separate influences of volunteers' personal motives and their team leaders' behaviors on volunteer satisfaction and contributions, along with mediating processes suggested by self‐determination theory. Participants were 302 volunteers who worked in teams at various sites through a central agency. As predicted, both personal motives for volunteering and transformational leadership influenced volunteer satisfaction through enhanced work meaningfulness and higher‐quality team relationships. However, motives that predicted volunteer contribution were different from those that predicted satisfaction. Whereas satisfaction was positively associated with motives concerning esteem enhancement and value expression, contribution was positively associated with motives to gain understanding and negatively related to motives pertaining to esteem enhancement and social concerns. Transformational leadership was positively associated with volunteer satisfaction, but not with volunteer contributions. The theoretical ramifications of these findings are discussed, along with practical implications for the recruitment and retention of volunteers. 相似文献

We gathered information on the cost-effectiveness of life-saving interventions in the United States from publicly available economic analyses. "Life-saving interventions" were defined as any behavioral and/or technological strategy that reduces the probability of premature death among a specified target population. We defined cost-effectiveness as the net resource costs of an intervention per year of life saved. To improve the comparability of cost-effectiveness ratios arrived at with diverse methods, we established fixed definitional goals and revised published estimates, when necessary and feasible, to meet these goals. The 587 interventions identified ranged from those that save more resources than they cost, to those costing more than 10 billion dollars per year of life saved. Overall, the median intervention costs $42,000 per life-year saved. The median medical intervention costs $19,000/life-year; injury reduction $48,000/life-year; and toxin control $2,800,000/life-year. Cost/life-year ratios and bibliographic references for more than 500 life-saving interventions are provided. 相似文献

In this study, we investigate how the institutional environment affects shareholders’ reaction to a firm’s announcement of divestitures. Traditionally, divestiture research has adhered to a financial economics perspective, in which shareholders anticipate certain economic outcomes from corporate divestitures and react accordingly. However, this research has not delivered a distinct understanding of the performance effects of corporate divestitures. To structure and integrate previous work, we apply a neo-institutional perspective of the stock market. We argue that at certain times, the institutional support for corporate diversification is relatively low. During these periods, there is a high rate of divestitures. The high divestiture activity legitimizes this corporate action and leads to a positive reaction of the stock market to new divestiture announcements. This means that individual evaluations of the possible performance outcomes of divestments are not the only factor determining the stock market reaction to a corporate divestiture announcement. Rather, investors might consider the perceived institutionalization of this corporate action when making their purchasing decisions. Using a meta-analytical technique, we find support for our prediction that different performance effects of divestitures, as revealed by previous studies, can be attributed to different conditions of the macro-economic environment. We discuss the implications of this result for research and management practice. 相似文献

The potential effects of maternal trauma on mother–infant interaction remain insufficiently studied empirically. This study examined the effects of the September 11, 2001, trauma on mother–infant interaction in mothers who were pregnant and widowed on 9/11, and their infants aged 4–6 months. Split‐screen videotaped interaction was coded on a one‐second basis for infant gaze, facial affect, and vocal affect; and mother gaze, facial affect, and touch. We examined the temporal dynamics of communication: self‐contingency and interactive contingency of behavior by time‐series methods. We documented heightened maternal and infant efforts at engagement in the 9/11 (vs. control) dyads. Both partners had difficulty tolerating moments of looking away as well as moments of negative behavior patterns. Heightened efforts to maintain a positive visual engagement may be adaptive and a potential source of resilience, but these patterns may also carry risk: working too hard to make it work. A vigilant, hyper‐contingent, high‐arousal engagement was the central mode of the interpersonal transmission of the trauma to these infants, with implications for intervention. 相似文献

The purpose of the authors in this study was to determine if the proportionality of peers who believe other youth are having oral sex or vaginal/anal intercourse influence the youth's intention to also have oral sex or vaginal/anal intercourse in the next three months. The results supported the hypothesis that the proportionality of perceiving one's peers as sexually active was correlated with one's intent to have oral sex in the next three months (r = .34 and .39, p < .01) and one's intent to have vaginal or anal sex within the next three months (r = .51 and r = .65, p < .01). Approximately 50% of youth who intent to have oral sex are also likely to have vaginal/anal sex. The results were not moderated by age, gender, or Hispanic/White status, but were moderated by being in a special/committed relationship. 相似文献

The Female Sexual Function Index (FSFI; Rosen et al., 2000) and International Index of Erectile Function (IIEF; Rosen et al., 1997) are two of the most widely used measures of sexual dysfunction. However, they have potential measurement and psychometric flaws that have not been addressed in the literature. This article examines the measurement capabilities of these measures based on data collected from an online study in 2010. A convenience sample of 518 sexually active adults (65% female) drawn from the general community were included in the analyses. Both measures displayed critical theoretical and measurement problems for the assessment of sexual problems beyond sexual arousal, and for the sexual desire domains in particular. Based on these results, we encourage clinicians and researchers to think critically about whether the FSFI and IIEF are appropriate measures for their practice and research. In particular, these measures are inappropriate for use among individuals who are not currently sexually active, and research with a focus other than sexual arousal should consider supplementary measures of sexual function. The psychometric properties of these measures should be reassessed in clinical samples, but the theoretical issues with the measures raised in this article are relevant across clinical and research contexts. 相似文献

Researchers have identified several aspects of nursing home care that interfere with residents' preservation of self. This paper examines how different models of care shape residents' opportunities for preserving a sense of self, adult identity, and agency. Using ethnographic data, I analyze staff practices in two facilities that reflect the contrast between the home and hospital models of long-term care. Previous research on long-term care suggests that an informal, “home-like” approach to care creates more opportunities for residents to preserve a sense of self-identity, whereas a formal, “institutional” approach fosters depersonalizing practices that interfere with residents' psychosocial well-being. My research suggests, however, that both approaches can have contradictory effects on residents' preservation of self. I analyzed patterns of objectification and infantilization that emerged in the social interactions between residents and staff members, as well as practices that mitigated these patterns. This study highlights how a larger culture of ageism and stigma surrounding dependency can become embedded in micro-level practices and underscores the challenges of defining and implementing “good” care. 相似文献

Unlike other life domains, sexual quality of life (SQoL) has a negative relationship with age. This study disentangled the effect of age in this relationship from confounding sociocultural influences (e.g., the period of time in which data were collected, and cohort differences) and aimed to understand the roles of other sexual domains (i.e., frequency, perceived control, thought and effort invested in sex, and number of sexual partners). We analyzed data from the longitudinal Midlife in the United States study (n = 6,278; age range 20–93), which were collected between 1995 and 2013. Repeated measures linear mixed-effects models showed that age was the most robust time-related predictor of declining SQoL. However, after the sexual domains were included in the model, age had a positive relationship with SQoL and older adults’ SQoL was differentially influenced by the quality—not quantity—of sex. When partnership characteristics were included in the model, age was no longer related to SQoL. These findings suggest that aging may be associated with the acquisition of skills and strategies that can buffer age-related declines in SQoL, particularly in the context of a positive relationship. We summarize these findings as sexual wisdom. 相似文献

Sexual dysfunctions commonly co-occur with various depressive and anxiety disorders. An emerging framework for understanding the classification of mental disorders suggests that such comorbidity is a manifestation of underlying dimensions of psychopathology (or “spectra”). In this review, we synthesize the evidence that sexual dysfunctions should be included in the empirical taxonomy of psychopathology as part of the internalizing spectrum, which accounts for comorbidity among the depressive and anxiety disorders. The review has four parts. Part 1 summarizes the empirical basis and utility of the empirical taxonomy of psychopathology. Part 2 reviews the prima facie evidence for the hypothesis that sexual dysfunctions are part of the internalizing spectrum (i.e., high rates of comorbidity; shared cognitive, affective, and temperament characteristics; common neural substrates and biomarkers; shared course and treatment response; and the lack of causal relationships between them). Part 3 critically analyzes and integrates the results of the eight studies that have addressed this hypothesis. Finally, Part 4 examines the implications of reconceptualizing sexual dysfunctions as part of the internalizing spectrum, and explores avenues for future research. 相似文献
