Despite the developmental and clinical relevance of this area of inquiry, no studies have examined the interrelations of trait vulnerabilities in the affective, behavioral, and interpersonal domains between mothers and their infants. Thus, this study examined the interrelations of three trait vulnerabilities (i.e., negative affective intensity, impulsivity, and insecure attachment) between mothers and their 12‐ to 23‐month‐old infants, focusing in particular on the unique and interactive influence of these maternal trait vulnerabilities on the expression of and precursors to these traits in their infants. Mother–infant dyads (= 101) completed several laboratory procedures, and mothers reported on their own and their infants' expressions of the trait vulnerabilities of interest. Findings from this study provide preliminary evidence for intergenerational relations between these traits and suggest that it is the confluence of trait vulnerabilities in mothers that relates to the early expression of some of these traits in infants.  相似文献

Objectives: This study assessed the extent to which consuming alcohol prior to sexual activity influenced college students' verbal/behavior cues utilized to communicate consent (external consent) as well as their feelings associated with consent (internal consent). Methods: Data was collected via paper-and-pencil surveys administered to heterosexual college students (N = 794) in the United States. Results: After controlling for gender, relationship status, rape myth acceptance, and alcohol expectancies, findings indicated that alcohol consumption prior to sexual activity was associated with both internal and external consent. Conclusions: Current findings can help inform sexual assault prevention education programming given the high rates of sexual assault occurring on college campuses that involve alcohol consumption.  相似文献

The existing literature on the effects of FDI inflows on domestic firms' performance offers ambiguous evidence. Macro‐level studies suggest that the characteristics of inward FDI and the ‘absorptive capacity’ of the host economy matter in determining the sign (or the mere existence) of these effects. Studies based on micro‐level data have so far mostly focused on finding a nexus between FDI inflows and the productivity of domestic firms, suggesting that the effects might be highly heterogeneous. This article, using a recent firm‐level survey conducted by UNIDO in 19 sub‐Saharan African countries, explores the channels through which multinational enterprises may exert an impact on local firms: products’ market, input availability and costs, access to finance and export opportunities, and analyses the strategic reactions of domestic firms induced by the presence of foreign affiliates.  相似文献

The purpose of this paper is to improve understanding of the relationship between sense of place and community resilience, two concepts described and defined differently reflecting different disciplinary research, policies and practices. We draw on international literature that has focused on the interrelationship between these concepts in the context of natural disasters, as well as the findings of a multidisciplinary project in the post-earthquake Christchurch recovery context. We describe how we developed indicators of resilience linked to sense of place as it relates to home, neighbourhood and the city, including place-based social interaction and the role of scientific and technical information. Through integrating literature with the findings from project interviews and a survey, we offer new ways of considering ‘resilience’ and we discuss the implications of our findings for not just the Christchurch recovery, but for future response and recovery to natural disasters throughout New Zealand.  相似文献

Mexican American youth often engage in relatively high levels of prosocial behaviors. We theorize that this may be due to a cultural value system that encourages familism values, which, in turn, may foster the development of sociocognitive processes that promote prosocial behaviors. Two hundred and five Mexican American early adolescent youth (Mage = 10.9 years, SD = 0.84; 51% girls) reported their familism values, perspective taking, prosocial moral reasoning, and six types of prosocial behaviors. The results indicated that perspective taking partially mediated the relation between familism values and the specific prosocial tendencies theoretically linked to the Mexican American culture. The study demonstrated the utility of integrating cultural and traditional developmental mechanisms in attempting to explain prosocial behaviors.  相似文献
