The aim of this longitudinal study was to recogmize the work characteristics and personal resourcesthat are associated with burnout symptoms in the long term. The empirical analyses are based onsample data (n = 174) from a larger survey in 1986 and from a 10-year follow up in 1776 conducted inan international industrial foresty enterprise. The participants were drawn from those worken inFinland, the home country of the enterprise, who responded to the questionnaires at both times. Theparticipants were classified into those having no burnout and those with serious burnout. In order tocompare the groups a multivariate analysis of variance and t-tests for two independent groups wereused. Four job-related and five organizational factors, 10 work environment hazards and threeindividual variables wereused as a predictors. Change variables were formed from the predictors. Allthe significant changes in work and personal resources during 10 years had shifted to the positivedirection in the no-bumout group, and to the negative direction in the serious burnout group.Discriminant analysis was used to identify linear combinations of quantitative predictor variables thatbest characterized the differences between the groups. Both the cross-sectional and the longitudinalpredictors showed that factors related to the social processes at work seem to be crucial to burnout. Ofthe individual resources, a strong sense of coherence seems to be of particular importance.  相似文献

Researchers in the social norms area have previously focused primarily on alcohol consumption, paying comparatively less attention to drug use and sexual behavior. The major purposes of this study were to (1) compare perceptions of peer norms in the areas of alcohol use, drug use, and sexual behavior with actual behavior and (2) determine if a relationship existed between a student's perceptions of normative behavior and a student's actual behavior. Participants were 833 college students at a large, public university in the Northeast. Study participants overestimated alcohol use, drug use, and sexual behavior among their peers. There was also a positive relationship between actual behavior and perceived peer norms, although the effect sizes for all behaviors were small to moderate. The authors provide further support for the tenets of social norms theory and suggest that social norms interventions are appropriate both campus-wide and to targeted high-risk groups.  相似文献

Product and service innovation is important for brands to succeed in a competitive marketplace. As information technology advances, customer recognition becomes a growing industry trend; that is, brands track customers' purchase history, recognize and price discriminate between repeat and new customers.The trend of customer recognition has changed the nature and intensity of competition between brands. In this article, we examine how customer recognition and the associated changes in competition affect brands' incentives to invest in product and service innovation. We find that when brands have similar equity, customer recognition increases brands' incentives to invest in product and service innovation. However, when brands have sufficiently different equity, customer recognition leads the stronger brand to invest more and the weaker brand to invest less in product and service innovation. In addition, extant literature suggests that customer recognition reduces brand profits. In contrast, we find that customer recognition can increase the weaker brand's profit but decreases it more for the stronger brand. Thus, collecting customers' purchase history data for customer recognition can be beneficial for weaker brands but detrimental for stronger brands.  相似文献

Respondent-Driven Sampling (RDS) employs a variant of a link-tracing network sampling strategy to collect data from hard-to-reach populations. By tracing the links in the underlying social network, the process exploits the social structure to expand the sample and reduce its dependence on the initial (convenience) sample.The current estimators of population averages make strong assumptions in order to treat the data as a probability sample. We evaluate three critical sensitivities of the estimators: to bias induced by the initial sample, to uncontrollable features of respondent behavior, and to the without-replacement structure of sampling.Our analysis indicates: (1) that the convenience sample of seeds can induce bias, and the number of sample waves typically used in RDS is likely insufficient for the type of nodal mixing required to obtain the reputed asymptotic unbiasedness; (2) that preferential referral behavior by respondents leads to bias; (3) that when a substantial fraction of the target population is sampled the current estimators can have substantial bias.This paper sounds a cautionary note for the users of RDS. While current RDS methodology is powerful and clever, the favorable statistical properties claimed for the current estimates are shown to be heavily dependent on often unrealistic assumptions. We recommend ways to improve the methodology.  相似文献

Using data on 459 Latino ninth graders from the LA-SIAA and the NC-SIAA studies, we evaluate the specific educational values and beliefs that motivate the academic achievement of Latino youth and contrast the school experiences of Latino youth in an emerging Latino community, North Carolina, with the school experiences of youth living in a traditional settlement community, Los Angeles. Despite their greater fears of discrimination, we find that Latino youth in North Carolina are more academically motivated than their peers in Los Angeles. This is partially because they are more likely to be immigrants. Being an immigrant, having a stronger sense of ethnic identification, and having a stronger sense of family obligation were each linked to a more positive view of school environments. Therefore, these factors each partially explained the immigrant advantage in academic motivation and helped to counter the harmful effects of discrimination on academic motivation.  相似文献

The use of physical discipline within African American families is examined from a historical perspective within the context of institutionalized racism and racial disproportionality in the child welfare system. African American parenting strengths are explored, demonstrating that the use of physical discipline can be purposeful, controlled, and appropriate, utilized to protect African American children and instruct them how to behave and survive within a racist society. Available literature on corporal punishment is reviewed, and implications for culturally informed child welfare practice are provided.  相似文献

The bodies produced by the violent practice of suicide bombing are a source of horror and disgust. They are, in feminist psychoanalyst Julia Kristeva's concept, abject: that which defies borders and is expelled to create the self. As ‘abject bodies’, suicide bombers' bodies frustrate attempts at calculation and rational control of security risks, and, in their mutilated flesh, expose as unstable the idea of the body as a whole with clearly defined boundaries between inside and outside. Female suicide bombers, whose bodies are already considered ‘abject’, produce a politics of the body that exceeds narratives of victimhood, and whose very monstrosity symbolically threatens the foundations of the nation-state. Attempts at constructing subjects out of the mutilated bodily remains of victims and perpetrators of suicide bombings are key practices in the production of the state and gendered subjects. The practice of suicide bombing and efforts to recover and resignify bodies reveals how power molds and constitutes the border of the body and state simultaneously. The explosive body of the suicide bomber thus has destabilizing effects beyond the motivations of its perpetrators and exposes the political work necessary to maintain the illusion of secure, bounded bodies and states.  相似文献

Using data from a stratified random sample of 281 foreign‐born adolescents and their parents in the United States, this study provides data on migration‐related trauma exposures and examines how the migration process influences the risk of experiencing trauma and developing posttraumatic stress disorder (PTSD). We find that 29 percent of foreign‐born adolescents and 34 percent of foreign‐born parents experienced trauma during the migration process. Among those that experienced trauma, 9 percent of adolescents and 21 percent of their parents were at risk for PTSD. Pre‐migration poverty combined with clandestine entry into the U.S. increased the risk of trauma and the subsequent development of PTSD symptoms. Post‐migration experiences of discrimination and neighborhood disorder further exacerbated this risk, while social support and familism mitigated it. Our results emphasize the importance of understanding how factors prior to, during, and after migration combine to influence the health of immigrants.  相似文献

Evidence suggests collective action success is aided by organizations working in conjunction. Recent scholarship has refocused attention on what factors foster or impede coalition work. This article builds on the literature to show how the context in which coalitions emerge and act may be multiple and contradictory. Using data from extended field research, we examine two Mexican NGO coalitions to analyze how the intersection of national and local opportunity structures influenced their emergence and strategic action. We find that the impact of such influences may be contradictory. Democratization posed both threats and opportunities for the coalitions, providing impetus for their emergence, but limiting strategic choices as co-optation and neoliberalism undermined the opportunities created by democratization. We argue that the coalition members' interpretation of the local political context explains the divergent paths the two coalitions took over time.  相似文献

This article examines how the American perception of trachoma as a disease prevalent among East European Jewish migrants was adopted in Britain in the years immediately preceding the passing of the 1905 Aliens Act. Increasingly rigorous immigration law in the United States meant that a proportion of migrants who arrived were refused entry and were subsequently forced to return to Europe. Steamship companies' interests, however, meant that a number of those migrants debarred from America were returned not to European frontiers but to the United Kingdom. One of the most potent ramifications of this was that trachoma, the reason why 87 per cent of migrants were rejected from America on health grounds, was considered in Britain to embody Britain's role as the destination for those migrants not fit for settlement in America. The disease was picked up by the growing anti-immigration lobby, who used it as symbol of the ‘undesirability’ of the immigrant in Britain.  相似文献
