This study investigates the completion of the Ph.D. in economics. We use ex ante information, based upon reviewing individual applications from former doctoral students. Students need different skills to succeed at each distinct stage of the doctoral program. Significant determinants for passing the comprehensive exams include Graduate Record Exam (GRE) verbal and quantitative scores, a Masters degree, and prior focus on economics. By contrast, research motivation and math preparation play significant roles in completing the dissertation. GRE scores become insignificant for completion in the generalized ordered logit estimates, which emphasize the sequential nature of the Economics Ph.D. program . ( JEL I210)  相似文献

Extreme violence revolves around actions of individuals who are emotionally aroused and willing to kill themselves, if need be, to inflict harm on enemies. Terrorism, gangbanging, and genocide are conspicuous examples of extreme violence. This violence is ultimately driven by repressed negative emotions about self that are transmuted into variants of anger and combinations of anger with satisfaction‐happiness to produce emotions such as hatred, righteous anger, and vengeance. This theory combines symbolic interactionism's emphasis on identity and self with key ideas from gestalt theories, psychoanalytic theories, and interaction ritual theory as well as data from primatology, evolutionary biology, and neurology. I explain extreme violence as the outcome of several converging forces: the neurological capacity for humans as evolved apes to experience and express a large palate of high‐intensity emotions, the experience of shame in key institutional spheres, the repression of shame (and, at times, guilt and alienation as well as other highly charged negative emotions), the intensification and transmutation of these repressed emotions into variants and elaborations of anger, the making of external attributions blaming external targets for negative experiences, the portrayal of these targets in highly negative terms, and the charging up of positive emotions in interaction rituals directed at inflicting harm on external enemies.  相似文献

Two ethical dilemmas are discussed; breaching client confidentiality in order to intervene in the client's illegal behavior, and defining the role of evaluator as expert witness. The evaluation context concerns a combined program development and evaluation project with clients involved in family court proceedings for child abuse or neglect. Different perspectives, approaches, and experiences in resolving each dilemma are reviewed. The conclusion argues that approaches to ethical dilemmas in evaluation projects must go beyond techniques to disguise data, to include an assessment of the values and value commitments connected to the different roles an evaluator must perform.  相似文献

This article addresses the issue of how deeply social arrangements may penetrate into private emotion, in this instance, grief. It argues that the data necessary to address the issue satisfactorily are not available and thus current assumptions in the literature about the universality of the grief experience are at least suspect. However, there are theoretical reasons, derived from interactionist thought, to suspect that if certain components of the grief experience vary, so will the experience. Four of these components are examined (level of significance of the other who dies; definition of the situation surrounding the death; character of the self experiencing a loss through death; and the interactional situation/setting in which the prior three components occur). Evidence is also presented which is suggestive of space-time variation in these components. It is concluded that an assumption of the deep social shaping and thus the variability of grief is fruitful for further empirical inquiries.  相似文献

Principal component and correspondence analysis can both be used as exploratory methods for representing multivariate data in two dimensions. Circumstances under which the, possibly inappropriate, application of principal components to untransformed compositional data approximates to a correspondence analysis of the raw data are noted. Aitchison (1986) has proposed a method for the principal component analysis of compositional data involving transformation of the raw data. It is shown how this can be approximated by a correspondence analysis of appropriately transformed data. The latter approach may be preferable when there are zeroes in the data.  相似文献

The relationship between drug use, school performance, and academic aspirations among 446 Anglo and Hispanic youths, age nine to seventeen, is explored. Two groups of subjects--current substance users and non-users--were interviewed. Subjects in each comparison group were similar in age, ethnicity, and gender. Overall results, consistent with prior research, indicate a significant relationship between current school performance, future educational aspirations, and drug use. No difference was noted between substance use groups on indicators of general interest in school work or probability of dropping out of school. Important differences in response patterns occurring with age, ethnicity, and gender were found.  相似文献
