Cyberbullying, the harassment of others via new technologies, is a growing phenomenon with important consequences for its victims. Despite the growing interest in this new form of violence, only a few longitudinal studies have analyzed the relationship between cyberbullying victimization and psychological problems, such as depression, in adolescents. Furthermore, the mechanisms through which cyberbullying victimization contributes to the development of depressive symptoms remain almost unexplored. The current study assesses whether cyberbullying victimization predicts the increase in depressive symptoms over time and the role of body image and cognitive schemas in the association between cyberbullying victimization and depression. We hypothesized that victims of cyberbullying would develop a negative body image, the belief that others would hurt them and that they were defective to some degree, and that, as a consequence of these cognitions, they would increase their symptoms of depression. A sample of 1015 adolescents (mean age?=?15.43, SD?=?1.09) completed measures of depressive symptoms at three waves (T1, T2, and T3) spaced 6 months apart, measures of body image and cognitive schemas at T1 and T2, and measures of CB victimization at T1. Findings indicated that CB victimization at T1 predicted a worsening of body image and cognitive schemas of mistrust and defectiveness at T2, and those changes in cognitions predicted in turn an increase in depressive symptoms from T2 to T3. Gender differences were also examined. The model was very similar for boys and girls. However, changes in body image acted as a mediator between CB victimization and depression only in girls. Therefore, this study contributes to clarifying the cognitive mechanisms involved in the development of depression among victims of CB. These findings suggest that intervention programs with victims of CB should address the cognitions that are relevant for the development of depression.  相似文献

This paper tests the efficiency hypothesis of the knowledge spillover theory of entrepreneurship. Using a comprehensive database for 63 countries for 2012, we employ data envelopment analysis to directly test how countries capitalize on their available entrepreneurial resources. Results support the efficiency hypothesis of knowledge spillover entrepreneurship. We find that innovation-driven economies make a more efficient use of their resources, and that the accumulation of market potential by existing incumbent businesses explains country-level inefficiency. Regardless of the stage of development, knowledge formation is a response to market opportunities and a healthy national system of entrepreneurship is associated with knowledge spillovers that are a prerequisite for higher levels of efficiency. Public policies promoting economic growth should consider national systems of entrepreneurship as a critical priority, so that entrepreneurs can effectively allocate resources in the economy.  相似文献

Government effectiveness could be explained by the level of well-informed electorate members, who use the press to learn more about politicians and public servants. Thus, a free press may improve citizens’ accessibility to this information, which in turn will make it more difficult for politicians and public servants to cover up or get away with corrupt behaviour, so the quality of the government could be affected by the media freedom. Accordingly, the main aim of this paper is to determine the effect of the freedom of the press on government effectiveness, considering additionally environmental, institutional, and political characteristics as factors that could determine the level of government effectiveness. To achieve this aim, we examined 202 central governments and compared them across countries using the World Bank data set of Governance Indicators for 2002–2008. The results show that the media, the organizational environment, and political characteristics may be determinants of the level of government effectiveness, taking countries’ economic development into account.  相似文献

As drug control policy reform trends toward marijuana decriminalization, focus will shift to opiate enforcement which, in turn, accentuates substance abuse treatment. While the national offender reentry movement has effected widespread implementation of programming for co-occurring substance abuse and mental health disorders, the practice of Medicated Assisted Treatment (MAT) is nonstandard throughout the criminal justice system despite its evidence based status. This paper observes MAT delivered within and by the criminal justice system as indicated by evidence rated programs and practices listed in the national criminal justice evidence based registry crimesolutions.gov. Observation of these programs’ treatment orientation, client populations, delivery settings, and operational status inform discussion for additional MAT implementation and program registry augmentation.  相似文献

The aim of this article is to investigate to what extent small‐firm foreign patents differ from those of their larger counterparts. The research setting consists of the population of U.S.‐owned small and large businesses with patent applications at the World International Patent Organization during 1996–2006 in the emerging field of nanotechnology. Findings reveal a significant and growing contribution of small firms to the globalization of patents. The analysis also suggests that small‐firm patents tend to be more novel and embedded in domestic innovation networks than large‐firm patents. Policy implications are multiple, including putting international patenting on the policy agenda and helping highly innovative small companies to explore foreign commercial opportunities in new markets of capital and technology.  相似文献

Now that racism has been officially recognized in Brazil, and some universities have adopted affirmative-action admission policies, measures of the magnitude of racial inequality and analyses that identify the factors associated with changes in racial disparities over time assume particular relevance to the conduct of public debate. This study uses census data from 1950 to 2000 to estimate the probability of death in the early years of life, a robust indicator of the standard of living among the white and Afro-Brazilian populations. Associated estimates of the average number of years of life expectancy at birth show that the 6.6-year advantage that the white population enjoyed in the 1950s remained virtually unchanged throughout the second half of the twentieth century, despite the significant improvements that accrued to both racial groups. The application of multivariate techniques to samples selected from the 1960, 1980, and 2000 census enumerations further shows that, controlling for key determinants of child survival, the white mortality advantage persisted and even increased somewhat in 2000. The article discusses evidence of continued racial inequality during an era of deep transformation in social structure, with reference to the challenges of skin color classification in a multiracial society and the evolution of debates about color, class, and discrimination in Brazil.  相似文献

In the light of the increasing political influence on German universities (amongst others, the excellence initiative) with effects on the selection of top positions, this article examines the appointment of chairs (department heads) in a “small” surgical specialty during the last 30 years. Following the delineation of official indicators of competence (inclusion criteria) within an appointment procedure, it can be shown that a broad distribution of institutions and persons that meet these criteria exists. The empirical examination of the actually successful occupations shows that closure mechanisms play a role because the successful candidates stem from no more than 10 out of 34 clinical departments. The monetary capital in terms of third-party funds is the most important allocation criterion, but cannot sufficiently explain the way appointments take place. As there are candidates who in formal terms are in a wide measure equally qualified, and a consequential uncertainty of the basis of decision within an appointment procedure, the derivation of the candidate in terms of a personal relationship to a chair holder (department head) from whose clinic he applies and who acts as a patron, proves to be the decisive distinction following the examination of all inclusion criteria. This results in a reproduction of the chair holders (department heads) largely from the same clinical departments and the formation of an academic caste system. In perspective, this cartel-like closure appears to be getting increasingly worse.  相似文献

The European Union (EU) constitutes an evolving diplomatic milieu characterized by high levels of interconnectedness among the politico-administrative apparatuses of member states. The article assesses whether the continued presence of member state bilateral embassies in the EU is residual and largely emptied of function, or whether they are adapting their role to new requirements in the EU policy environment. An analytical framework is developed conceptualizing diplomatic representation around three variables—function, access and presence—and two scenarios of change dynamics in the structures of bilateral diplomacy in the EU are proposed. These are then utilized to evaluate empirical evidence gathered in embassies of six member states in London and Vienna. The findings reveal a process of gradual ‘re-gearing’ of embassy functions towards EU matters, shifting patterns of communication and access, and ‘domestication’ of diplomatic presence in terms of personnel and agenda. Overall, this amounts to a shift towards EU-oriented bilateralism.  相似文献
