The aim of this study was to analyze the psychometric properties of two instruments that assess attitudes justifying use of aggression in adolescents?? dating relationships: the Attitudes About Aggression in Dating Situations (AADS) and the Justification of Verbal/Coercive Tactics Scale (JVCT). The sample was made up of 2,856 adolescents from different high schools of Madrid. Results supported the three-factor structure for the AADS and the six-factor structure for the JVCT, which was consistent with the theory and with previous research. As expected, the relation between attitudes and aggressive behavior was between small and moderate but significant in most cases. Furthermore, attitudes differed depending on the type of violence, the respondent??s sex, and on whether aggression is carried out by a man or a woman. Finally, the potential applications of these two scales are discussed, and it is concluded that both constitute useful tools to assess justification of aggression in dating relationships in young couples. 相似文献

Emerging technologies, including nanotechnologies, are generally seen as those latest scientific innovations which have a potential impact on industry structure, and commercialization and economic potential. Work in this area of emerging technologies has distinct boundary spanning characteristics from the perspective of academic science. First, many emerging technologies involve collaboration of scientists across disciplinary boundaries. Second, because of the commercializability of many emerging technologies, scientists may interact more often with industry throughout the research and commercialization process. We ask, what are the boundary-spanning characteristics of scientists engaged in emerging technology research and how do those characteristics matter in obtaining funding in this area? We examine the characteristics of academic scientists in the United States who are employed in research intensive institutions and who are engaged in funded research in the area of emerging technologies. We address the factors that predict their grant success in areas of emerging technology. Findings reveal that interdisciplinary activities and industry orientation are both important in predicting funding in areas of emerging technology. Moreover, the findings imply that the emergence of new technologies may offer opportunities for women in low representation fields. 相似文献

Do voters hold local officials accountable for government performance? Using over a decade of panel data on school district elections and academic achievement in California, I causally identify the effect of test score changes on school board incumbent re‐election rates and show that incumbents are more likely to win re‐election when test scores improve in their districts—but only in presidential election years. This effect disappears in midterm and off‐years, indicating that election timing might facilitate local government accountability. 相似文献

A new pairwise osteometric pair‐matching approach based on the Z‐transform method is presented. In contrast to previous methods that perform a global t‐test on the summed skeletal element pair measurement distances, this approach performs t‐tests on each individual distance, facilitating the capture of measurement‐specific variation. This new approach is compared to published pairwise sorting methods using a standard reference dataset of postcranial remains maintained by the Defense POW/MIA Accounting Agency. Receiver operating characteristic curve analysis indicates significantly improved performance for the clavicle and radius over all previous methods (p < 0.01). The z‐transform method weighted by the effect size outperformed the t‐test (Byrd and Adams) and the mean t‐test (Lynch) for all elements (p < 0.01). The method performed better than the absolute value t‐test (Lynch) for five elements (p < 0.01) and performed at least as well for the remainder.

This study provides an update on a quantitative method for immature age estimation based on postnatal deciduous mandibular tooth length. Two known sex and age skeletal collections from Western Europe were sampled (n = 97). Linear regression models for age estimated were calculated for each individual tooth, each sex, and sex combined sample using classical calibration. Prediction errors, residuals, and percentage of individuals whose real age fell within the 95% prediction interval were calculated. The teeth which develop earlier in life, the incisors and the first molar, showed the greatest precision, while the canine showed the least. This method has greater applicability to archeological skeletons or to children in developing countries than for use in North American or European forensic contexts. The method can be applied to incomplete or poorly preserved remains of unknown sex, particularly when dental radiographs are not an option or when teeth have been removed from the alveolus or crypt. 相似文献

Examining personal beliefs about social justice in the way a society provides financial security in old age may reveal potential conflicts about the distribution of wealth. Individuals differ with regard to how they believe old-age provisions should be distributed (e.g., based on principles of merit or self-reliance), and individuals often endorse more than one belief at the same time. Using latent profile analysis and data from the 2014 German Ageing Survey we identify five separate profiles of social justice beliefs among older adults (40–85 years) in Germany. Belief profiles were based on the extent to which people simultaneously endorse and/or reject meritocratic, redistributive, self-reliant, and fatalistic ideas regarding old-age provisions. Almost 20% of the sample demonstrated a belief system in line with the German meritocratic system. Roughly three-fifth did not show strong preferences for a specific social justice principle. However, we identified two belief profiles representing 22.4% of the sample which may reflect dissent from the current system. Sociodemographic characteristics, political identification, and indicators of social disadvantage (e.g., lower income, fears of decline in social status, and feelings of social exclusion) were differentially associated with the five belief profiles. Overall, the results showed that in particular people of lower socioeconomic status were critical with respect to the principles of the German pension system raising questions regarding the demand of political interventions. 相似文献

Neuropsychological consequences in female survivors of intimate partner violence are being used in courts as evidence of acquired injury and for criminal exculpation. To support the validity of neuropsychological test performance and the veracity of victim testimony, effort tests can be used by expert witnesses. Nevertheless, no study has evaluated whether the two principle types of effort tests, Symptom validity tests or Performance validity tests, are most adequate for this population. The study’s objective was to compare the false positive rates of a Performance validity test (Test of Memory Malingering: TOMM) and a Symptom validity test (Structured Inventory of Malingered Symptomatology: SIMS). The sample included 68 female intimate partner violence victims and 40 control females. SIMS showed a significantly higher rate of false positives in victims on four of five subtests, reaching a 59.3% in the total score. There were 0% false positives in both groups on the TOMM. Findings indicate that the SIMS may incorrectly score female IPV victims, undermining the victim’s testimony in judicial cases. 相似文献
