This article studies the reaction of automotive component suppliers in Hungary to the 2008–2009 economic crisis. We find that the global suppliers viewed the crisis as an opportunity to reinforce the competitiveness of their Hungarian affiliates by engaging in product and process upgrading, and upgrading through research and development. The regional suppliers combined defensive strategies aimed at reducing costs with offensive measures in the form of product upgrading, production upgrading and expansion into new markets. The local suppliers reduced costs and reduced their workforce, but also reacted offensively by expanding into new markets, upgrading their activity and collaborating with other local suppliers. 相似文献

Childhood sexual abuse has been associated with HIV transmission risk behavior in men who have sex with men. This study examined an adapted model that was originally developed to explain the relationship between childhood sexual abuse and HIV risk behavior among women in a sample of men who have sex with men. Men attending a large gay pride event (n=647) completed anonymous surveys that assessed demographic characteristics, childhood sexual abuse, symptoms of dissociation, trauma-related anxiety, borderline personality characteristics, hopelessness, substance use, and sexual risk behavior. A latent variable partial least squares analysis was conducted to test the interrelationships between childhood sexual abuse, exchanging sex for money or drugs, emotional disturbances, drug use, substance use in the context of sexual behavior, and sexual risk behavior. The model fit the data well and accounted for 10% of the total variance in sexual risk behavior. History of childhood sexual abuse predicted exchanging sex for money or drugs and this relationship was partly accounted for by active drug use. Substance use proximal to sexual behavior also emerged as a key factor in predicting sexual risk behavior. Findings from this study, therefore, indicate a direct association between history of child sexual abuse and high risk for HIV infection related to engaging in sex trade. 相似文献

Innovation by users is now understood to be an important part of innovative activity in the economy. In this paper we explore the implications of adding innovation by users to existing models of social welfare that currently assume innovation by manufacturers only. We find this addition removes several inefficiencies, and that social welfare is likely to be increased by the presence of user innovation. Implications for policies that can impact users' freedom to innovate are discussed. 相似文献

We argue that partisan elected judges have an incentive to redistributewealth from out-of-state defendants (nonvoters) to in-stateplaintiffs (voters). We first test the hypothesis by using cross-statedata. We find a significant partisan effect after controllingfor differences in injuries, state incomes, poverty levels,selection effects, and other factors. One difference that appearsdifficult to control for is that each state has its own tortlaw. In cases involving citizens of different states, federaljudges decide disputes by using state law. Using these diversity-of-citizenshipcases, we conclude that differences in awards are caused bydifferences in electoral systems, not by differences in statelaw. 相似文献
