Abstract

The endorsement of anti-corruption norms is a normative assumption in legal systems with freedom of information acts, where citizens are expected to act as monitors of the public service. Tolerance of corruption counteracts this assumption. We studied tolerance of corruption among 8th graders from Latin-American samples of the International Civic and Citizenship Study 2009. We proposed a model where associations between students’ socioeconomic status (SES) and tolerance of corruption are explained by civic knowledge, authoritarianism and open classroom discussion. This model accounted for 36–43% of the variance within schools, and 87–96% of the variance between schools, across six countries. The socioeconomic gap in tolerance of corruption was mainly present between schools. In addition, students with higher civic knowledge were less tolerant of corruption, partially explained by authoritarianism, while open classroom discussion also had indirect associations with tolerance of corruption.  相似文献

This article examines the school choices of families who have recently experienced downward mobility during the economic crisis in Spain. Based on semi-structured interviews we analyse the educational strategies of the families in a Bourdieusian framework, focusing on how they cope with the loss of their perceived social status. Prior to the crisis, these families of working-class origin improved their social position as a result of their success in economic capital accumulation with a humble increase in social and cultural capital. Our research suggests that the concerns of families confronted with downward social mobility are manifested in tensions related to their school choice in terms of their strategies of resistance and negotiation with regards to the ownership, social composition and corresponding perceived quality of the school. School can symbolically represent the last resort, an indispensable investment in one’s own future and that of the next generation.  相似文献

This paper examines the propensity of African American students to graduate from Historically Black Colleges and Universities (HBCUs). Using IPEDS data from 2004 to 2016, we take care in developing a control group of institutions from which to compare HBCU success. Results suggest that despite accepting more students who are at risk of not graduating, HBCUs have a higher graduation rate for African American students than their peers. We then show that gender nor major choice help explain this persistent difference.

Currently, libraries and other information services are facing new professional challenges in relation to digitization policies and orphan works after the publication of European Directive 2012/28/EU on certain permitted uses of orphan works and Spanish Royal Decree 224/2016. This paper aims to analyse how Spanish library and information centres specialising in theatre and performing arts meet users' textual and non-textual information needs, by respecting copyright issues and being involved in a dynamic and digital environment. For this purpose, an online questionnaire, which was used as a methodological tool, was sent to library directors in February 2018. At the same time, some research questions based on orphan works and digitisation approaches are discussed in the paper, specifically in reference to graphic and audiovisual materials.  相似文献

A multi-national study using the Social Competence and Behavior Evaluation Inventory (SCBE-30) was conducted to investigate preschool children's social and emotional development across cultures. A total of 4,640 children from eight participating countries, including Austria, Brazil, Canada, China, Italy, Japan, Russia, and the United States were evaluated by their preschool teachers. The main objective of the study was to validate the SCBE-30 in each country and build a cross-cultural data set for the investigation of universals, as well as cultural differences, in the development of preschool children's social competence and the frequency and type of their behavioral problems. Results provide a clear case for the structural equivalence of the SCBE-30 across all samples, for universals in the structure of early social behavior, and possibly some differences that may be attributed to culture. The pattern of gender differences found in North American samples was found to generalize across cultural contexts as preschool boys were universally reported to be significantly more aggressive and viewed as less socially competent than girls. Age differences were also found in all eight samples reflecting increasing competence in older children, however age trends in the prevalence of behavior problems were culture specific.  相似文献

The research self-efficacy and motivation of foreign language (FL) faculty in periphery countries is under-researched, yet there is a need to understand the impact of public policies that drive such faculty to conduct research. This paper reports a qualitative case study investigating research self-efficacy and research motivation in a group of Mexican FL professors. Interview data show variation in self-efficacy levels connected with academic degree, motivation types and strategic behaviors. Professors with doctorates, intrinsic motivation and use of strategies showed the highest self-efficacy. Professors with master's degrees and low motivation show the lowest self-efficacy. Previous experience and mentoring are influential sources of self-efficacy. Policies such as forced collaboration, financial rewards and the threat of employment termination seem to exert some effect on self-efficacy. It is recommended that policies be enacted to recognize and promote mentoring formally.  相似文献

Social support and parenting in poor,dangerous neighborhoods   总被引:1,自引:0,他引:1  
This study investigated how stressful environmental conditions influence the relation between mothers' social support and parenting strategies, utilizing interview data from a sample of 262 poor, African American single mothers and their seventh- and eighth-grade children, as well as objective data about respondents' neighborhoods. In general, the results indicated that neighborhood conditions moderate the relation between social support and parenting behaviors. Specifically, as neighborhood conditions worsened, the positive relation between emotional support and mothers' nurturant parenting was weakened. In a similar fashion, the negative relation between instrumental social support and punishment was stronger in better neighborhoods. As the surrounding environments became poorer and more dangerous, the relation between greater instrumental support and a lower reliance on punishment was weakened. Thus, on the whole, hierarchical regression analyses indicated that the positive influences of social support on parenting behavior were strained and attenuated in poorer, high-crime environments.  相似文献

A qualitative study probing the connection between a high school English teacher’s lived experience and beliefs about teaching students identified as having a disability using interview story method was undertaken. Struggles with family quickly emerged as a dominant storyline in the participant’s discussion of her beliefs about teaching such students. The teacher’s value of diversity in students, regardless of disability/ability status, evolved from family relations. The narrative also illuminates the importance of persistence and compromise in preserving and developing relationships that extend to colleagues and students. Lessons learned from gathering the narrative are also discussed.  相似文献

Abstract

The aim of this study was to assess the effect of intermittent hypoxia exposure on direct and indirect methods used to evaluate recombinant human erythropoietin (rhEPO) misuse. Sixteen male triathletes were randomly assigned to either the intermittent hypoxia exposure group (experimental group) or the control normoxic group (control group). The members of the experimental group were exposed to simulated altitude (from 4000 to 5500 m) in a hypobaric chamber for 3 h per day, 5 days a week, for 4 weeks. Blood and urine samples were collected before and after the first and the final exposures, and again 2 weeks after the final exposure. While serum EPO significantly increased after the first [from a mean 8.3 IU · l?1 (s = 3.2) to 16.6 IU · l?1 (s = 4.7)] and final exposures [from 4.6 IU · l?1 (s = 1.4) to 24.8 IU · l?1 (s = 9.3)], haemoglobin, percentage of reticulocytes, and soluble transferrin receptor were not elevated. Second-generation ON/OFF models (indirect rhEPO misuse detection) were insensitive to intermittent hypoxia exposure. The distribution of the urinary EPO isoelectric profiles (direct rhEPO misuse detection) was altered after intermittent hypoxia exposure with a slight shift towards more basic isoforms. However, those shifts never resulted in misinterpretation of results. The intermittent hypoxia exposure protocol studied did not produce any false-positive result for indirect or direct detection of rhEPO misuse in spite of the changes in EPO serum concentrations and urinary EPO isoelectric profiles, respectively.  相似文献
