This research aims at broadening the applicability and scope of network‐based explanations of international migration to include explanations of aggregated immigration dynamics for multiple immigrant collectives. Using a unique dataset that contains data on approximately 4.5 million international immigration events from 180 different origin countries in Spain between 1999 and 2009, my analysis shows conclusively that information about changes in the supply of immigrant social capital between past and potential immigrants explains the variation in local immigration rates in the destination society. It also show that incorporating information about such social network influences is very informative when the goal is to explain (1) temporal variation in intra‐collective international immigration flows across different locations in the destination, (2) temporal variation in inter‐collective international immigration flows within a specific location in the destination, (3) intra‐collective differences in international immigration across locations in the destination, and finally (4) inter‐collective differences in local international immigration within the same geographical location in the destination.  相似文献

Research suggests that hurricane‐related risk perception is a critical predictor of behavioral response, such as evacuation. Less is known, however, about the precursors of these subjective risk judgments, especially when time has elapsed from a focal event. Drawing broadly from the risk communication, social psychology, and natural hazards literature, and specifically from concepts adapted from the risk information seeking and processing model and the protective action decision model, we examine how individuals’ distant recollections, including attribution of responsibility for the effects of a storm, attitude toward relevant information, and past hurricane experience, relate to risk judgment for a future, similar event. The present study reports on a survey involving U.S. residents in Connecticut, New Jersey, and New York (n = 619) impacted by Hurricane Sandy. While some results confirm past findings, such as that hurricane experience increases risk judgment, others suggest additional complexity, such as how various types of experience (e.g., having evacuated vs. having experienced losses) may heighten or attenuate individual‐level judgments of responsibility. We suggest avenues for future research, as well as implications for federal agencies involved in severe weather/natural hazard forecasting and communication with public audiences.  相似文献

Being self-sufficient, having an economy of your own, does not only safeguard basic resources such as food and shelter but is also a prerequisite for ensuring full participation in society. Research shows that women subjected to domestic violence often suffer from economic abuse and experience economic hardship within and after their relationships. Without economic support it is harder for abused women to break up and the risk of returning to a violent partner increases. The aim of the article is to understand how survivors of domestic violence experience financial vulnerability and what implications these experiences have on social work within the social assistance system. Based on 13 in-depth interviews with women survivors, our study describes how debts and stolen money, together with difficulties on the labour market, affect their ability to have a reasonable economic standard (long) after breaking up. Several of the women describe how social workers in different ways have recognized them by giving emotional support, cognitive respect and social esteem. However, social workers have also mimicked patterns of abuse from their ex-partners.  相似文献

The purpose of this study was to examine rural versus non-rural differences in the following risk factors among sexual minority adults: victimization/discrimination, fundamental religiosity, identification and involvement in the lesbian, gay, bisexual, and transgender (LGBT) community, social support, and level of comfort disclosing sexual identity to others. The study recruited sexual minority individuals via online communications to LGBT organizations. Of the total sample (N = 699), 23.3% resided in rural areas and 76.7% resided in non-rural areas. A MANCOVA was conducted to determine if there was a significant overall relation of rural versus non-rural location to the five risk factors of interests, while controlling for age, sex, race, relationship status, and sexual identity. Post hoc ANCOVAs were then conducted to explore the specific directionality of the significant differences. Results revealed rural sexual minorities reported greater identification with fundamental religious beliefs, less comfort in disclosing their sexual identity to others, more experiences of victimization and discrimination, less identification with and involvement in the LGBT community, and less perceived social support when compared to their non-rural counterparts. These findings suggest sexual minorities residing in rural areas may experience increased exposure to negative risk factors. Implications for mental health providers working with rural sexual minorities are discussed.  相似文献

The sustainability of changes in well-being achieved via positive interventions is challenged by findings that happiness levels are constrained by a homeostatic set-point. In this paper, we propose that while generally stable, the neurological and psychophysiological bases of well-being demonstrate plasticity. The neurobiological underpinnings of the hedonic component of well-being are first reviewed, demonstrating the value of both central (such as frontal asymmetry) and peripheral (such as heart rate variability) indices. Convergent evidence that certain well-being interventions are capable of modifying subjective, central and peripheral indices of positive affect or regulation of negative affect is then reported, although there is a clear need for longitudinal research to demonstrate the longevity of changes. It is recommended that a multi-level approach to evaluating positive interventions incorporating subjective psychosocial and neurobiological indices of affective change is adopted by researchers in an attempt to identify interventions most likely to achieve sustained positive outcome. Accumulating evidence through rigorous research that positive interventions can enhance psychosocial and neurophysiological factors can provide a compelling case for more widespread dissemination through public health policy.  相似文献

Perception of Risk and the Attribution of Responsibility for Accidents   总被引:1,自引:0,他引:1  
Accidents, one often hears, “happen”; we accept, and even expect, that they will be part of daily life. But in situations in which injury or death result, judgments of responsibility become critical. How might our perceptions of risk influence the ways in which we allocate responsibility for an accident? Drawing from attribution and risk perception theory, this study investigates how perceived controllability and desirability of risk, in addition to perceived danger and recreational risk‐taking, relate to attributions of responsibility for the cause of unintentional injury in a unique setting: U.S. national parks. Three parks, Mount Rainier, Olympic, and Delaware Water Gap, provide the setting for this survey‐based study, which considers how park visitors (N = 447) attribute responsibility for the cause of a hypothetical visitor accident. Results suggest that respondents tended to make more internal (i.e., related to characteristics of the victim), rather than external (i.e., related to characteristics of the park, or park management) attributions. As respondents viewed park‐related risk as controllable, they were more likely to attribute the cause of the accident to the victim. Moreover, among other significant variables, having experienced a similar accident predicted lower internal causal attribution. Opportunities for future research linking risk perception and attribution variables, as well as practical implications for the management of public outdoor settings, are presented.  相似文献
