The present study examined racial, ethnic, and gender differences in family composition substance abuse, and mental health issues, such as depression and self-esteem among adjudicated juvenile offenders. Results revealed a negative relationship between depression and self-esteem among all ethnicities and family compositions. Caucasians reported greater incidence of substance abuse than did African American and Hispanic youth. Moreover, in reconstituted families, Caucasians had lower self-esteem scores than did other ethnicities. The findings illustrate the complexities of risk to substance use among high-risk populations, particularly as they relate to familial factors and the importance of intensive family therapy among this population.  相似文献

This paper identifies a tension in Frege’s philosophy and offers a diagnosis of its origins. Frege’s Context Principle can be used to dissolve the problem of propositional unity. However, Frege’s official response to the problem does not invoke the Context Principle, but the distinction between ‘saturated’ and ‘unsaturated’ propositional constituents. I argue that such a response involves assumptions that clash with the Context Principle. I suggest, however, that this tension is not generated by deep-seated philosophical commitments, but by Frege’s occasional attempt to take a dubious shortcut in the justification of his conception of propositional structure.  相似文献

The unique and interactive contributions of past externalizing behavior, negative parenting, and teacher-child relationship quality to externalizing behavior trajectories after the transition to school were examined. In a sample of 283 children, random regression analyses indicated that conflict in the teacher-child relationship during the school transition contributed to faster rates of increase in externalizing behavior from kindergarten through third grade above and beyond negative parenting and initial levels of externalizing behavior. A significant interaction between teacher-child closeness and the externalizing behavior intercept indicated that decreases in externalizing behavior were associated with teacher-child closeness, especially for children with the highest levels of externalizing behavior upon school entry. Family socioeconomic status and initial levels of classroom externalizing behavior in kindergarten were also significant contributors to the prediction of externalizing behavior trajectories.  相似文献

In this paper, I develop the notion of an epistemic side constraint in order to overcome one of the main challenges to a goal‐based approach to the structure of epistemic normativity. I argue that the rationale for such side constraints can be found in the work of John Locke and that his argument is best understood as the epistemic analog to David Gauthier's argument as to the rationality of being moral.  相似文献

The authors conducted a Monte Carlo simulation of 8 statistical tests for comparing dependent zero-order correlations. In particular, they evaluated the Type I error rates and power of a number of test statistics for sample sizes (Ns) of 20, 50, 100, and 300 under 3 different population distributions (normal, uniform, and exponential). For the Type I error rate analyses, the authors evaluated 3 different magnitudes of the predictor-criterion correlations (rho(y,x1) = rho(y,x2) = .1, .4, and .7). For the power analyses, they examined 3 different effect sizes or magnitudes of discrepancy between rho(y,x1) and rho(y,x2) (values of .1, .3, and .6). They conducted all of the simulations at 3 different levels of predictor intercorrelation (rho(x1,x2) = .1, .3, and .6). The results indicated that both Type I error rate and power depend not only on sample size and population distribution, but also on (a) the predictor intercorrelation and (b) the effect size (for power) or the magnitude of the predictor-criterion correlations (for Type I error rate). When the authors considered Type I error rate and power simultaneously, the findings suggested that O. J. Dunn and V. A. Clark's (1969) z and E. J. Williams's (1959) t have the best overall statistical properties. The findings extend and refine previous simulation research and as such, should have greater utility for applied researchers.  相似文献

The introduction of chromosomal microarray (CMA) into the prenatal setting has involved considerable deliberation due to the wide range of possible outcomes (e.g., copy number variants of uncertain clinical significance). Such issues are typically discussed in pre-test counseling for pregnant women to support informed decision-making regarding prenatal testing options. This research study aimed to assess the level of informed decision-making with respect to prenatal CMA and the factor(s) influencing decision-making to accept CMA for the selected prenatal testing procedure (i.e., chorionic villus sampling or amniocentesis). We employed a questionnaire that was adapted from a three-dimensional measure previously used to assess informed decision-making with respect to prenatal screening for Down syndrome and neural tube defects. This measure classifies an informed decision as one that is knowledgeable, value-consistent, and deliberated. Our questionnaire also included an optional open-ended question, soliciting factors that may have influenced the participants’ decision to accept prenatal CMA; these responses were analyzed qualitatively. Data analysis on 106 participants indicated that 49% made an informed decision (i.e., meeting all three criteria of knowledgeable, deliberated, and value-consistent). Analysis of 59 responses to the open-ended question showed that “the more information the better” emerged as the dominant factor influencing both informed and uninformed participants’ decisions to accept prenatal CMA. Despite learning about the key issues in pre-test genetic counseling, our study classified a significant portion of women as making uninformed decisions due to insufficient knowledge, lack of deliberation, value-inconsistency, or a combination of these three measures. Future efforts should focus on developing educational approaches and counseling strategies to effectively increase the rate of informed decision-making among women offered prenatal CMA.  相似文献
