Relatively few studies have examined psychological maltreatment as a risk factor for adolescent psychopathology. This cross-sectional study evaluated mother-adolescent conflict frequency, maternal support, and avoidant coping as mediators of relations between mother's degrading parenting and adolescent conduct problems and internalizing. Analyses were conducted to determine if relations between model constructs were influenced by reporter, gender, or ethnicity. The sample included 232 adolescents and their mothers. Household interviews were conducted with families who were randomly selected from two urban school districts. The proposed model was estimated using path analysis and generally fit the data well. Results suggested that mothers’ degrading parenting was associated with risk for internalizing and conduct problems, regardless of adolescent gender or ethnicity. Mother-adolescent conflict frequency mediated relations between mothers’ degrading parenting and adolescent adjustment. Maternal support and avoidant coping mediated relations between degrading parenting and internalizing when adolescent report was used.  相似文献

The aim of this study was to estimate the allelic frequencies of the 15 STR loci included in the AmpFlSTR Identifiler PCR Amplification Kit in a sample of 342 unrelated Caucasian individuals autochthonous from Spain to be used for forensic purposes and population studies. The combined power of discrimination and the combined power of exclusion for all of the 15 loci were 5.68x10(-18) and 0.9999964, respectively. According to the obtained data, the D18S51 locus may be considered the most informative among the tested loci.  相似文献

Haplotype data were obtained from a sample of 173 unrelated male individuals from Cartagena (Colombia), for 16 Y-chromosome STRs (DYS19, DYS385, DYS389 I, DYS389 II, DYS390, DYS391, DYS392, DYS393, DYS437, DYS438, DYS439, DYS460, DYS461, DYS635, GATA H4 and GATA A10). No shared haplotypes were observed, demonstrating the usefulness and informative power of these Y-STRs in male lineage identification in Cartagena. Genetic distances were calculated using previously published haplotype data and the lowest values were found for the comparisons with samples of Iberian origin.  相似文献

Private companies want to eliminate outgoing spillovers while policymakers seek to maximize them. With subsidized R&D cooperation agreements both agents partially achieve their objectives. For this reason, in Europe, policymakers grant subsidies for R&D activities with the condition of establishing R&D cooperation agreements. This study explores the relationship of complementarity between R&D subsidy, R&D cooperation and absorptive capacity in the context of its contribution to labor productivity of enterprises. The data used comes from the Technological Innovation Panel (PITEC), managed by the Spanish National Statistics Institute. We selected manufacturing companies in the period 2008–2013. We evaluate the existence of complementarity through the systems approach and the interaction approach. The econometric technique that we used to estimate the coefficients of our empirical model was maximum-likelihood random effects. As a consequence of the low absorptive capacity of Spanish manufacturing firms we find that R&D subsidies and R&D cooperation agreements are not complementary variables, i.e., receiving public subsidies as a result of establishing R&D cooperation agreements has a lower impact on productivity than the sum of the individual impacts of R&D cooperation and R&D subsidies. In consequence, this result calls into question the convenience of using subsidized R&D cooperation agreements as a tool for promoting innovation in EU countries as there are notable differences between the companies in these countries in terms of absorption capacity.  相似文献

The repression of anti-austerity protests in Spain from 2011 to 2014 constitutes an example of how neoliberal developments are facilitated by the penal system as it limits political resistances to the imposition of precarious working conditions and social cuts. The limits imposed on contentious politics are both material (consisting of banning acts that are prominent in social movement’s repertoire of contention, fining demonstrators, etc.) and symbolic (consisting of transforming the meaning of legitimate politics by imposing new legal and political definitions). This case study is used to illustrate the interconnection between labor markets, social policies and the repression of social protest, and to elaborate on Wacquant’s approach to the relationship between punishment and other social institutions. It is at such times of political and economic crisis when institutional interconnections seem particularly exposed, arguably enabling more profound analyses.  相似文献

Are the sociological profiles of radical right-wing populist parties' (RRPPs) representatives really unlike those of their counterparts in mainstream parties? Once RRPPs occupy positions of legislative power for an extended period, do their MPs' profiles increasingly converge with those of more mainstream parties? This paper examines three right-wing parties in Austria, Italy, and Switzerland (FPÖ, LEGA, and SVP), and shows how RRPPs' MPs persistently contrast the “diploma democracy”, that is the increasingly dominant high-educated trend in political representation. Inspired by the current scholarship's diachronic and comparative perspectives of political elites and MPs, the analysis focuses trends since the 1980s.  相似文献
