Skeletal remains removed from an unmarked grave in El Salvador were intensively studied by a team of forensic science experts. Even though the skull, teeth, and several major bones were missing, a positive identification was made of the missing journalist. This was contrary to reports submitted to the State Department by Salvadorian officials. All of the methods used in this investigation, which includes a new method for simultaneously assessing sex and race by discriminant function analysis that was tested by application, are fully described. The international background of this case and information regarding the cause of death is discussed.  相似文献

Depressive symptomatology and suicidal behavior were evaluated in a multiethnic sample of 48 delinquent females through ratings on self-reports and probation officers' reports. Psychological functioning of the subjects was also evaluated through the Diagnostic Interview for Borderlines, the Rorschach, and the WAIS or WISC-R in order to identify delinquent personality patterns. Four personality patterns were identified: the borderline, the antisocial, the neurotic, and the socialized delinquent personalities. A chi-square analysis of the data demonstrated that level of depression and frequency of suicidal behavior were both significantly related to personality patterns. Level of depression was also significantly related to ethnicity, but not to socioeconomic status. The results have implications for assessment and treatment of delinquent females and also raise issues concerning the interaction of personality, cultural factors, and delinquent behavior which should be addressed in future research with larger, socioculturally diverse samples.This research is based on the author's doctoral dissertation and was supported by a Pre-Doctoral National Research Service Fellowship award from the National Institute of Mental Health.Received her Ph.D. from the University of California at Berkeley in 1980. Major interest is adolescent psychopathology and delinquency.  相似文献

In this paper we provide a statistical analysis of authorship in Public Choiceover the past 30 years. We explore trends in article length andcoauthorship, as well as provide rankingsof individual authors and institutions bytotal pages published in the journal. Thisis the first such ranking of publicationsin the journal since 1987. We find asignificant degree of turnover among theleading authors in Public Choice, andthat George Mason University is clearly theleading institution making a large share ofthe new contributions in the field.  相似文献

Controversy persists over the link between turnout and the likelihood of success of Democratic candidates (e.g., DeNardo, 1980, 1986; Zimmer, 1985; Tucker and Vedlitz, 1986; Piven and Cloward, 1988; Texeira, 1992; Radcliff, 1994, 1995; Erikson, 1995a, b). We argue that the authors in this debate have largely been talking past one another because of a failure to distinguish three quite different questions. The first question is: “Are low turnout voters more likely to vote Democratic than high turnout voters?” The second question is: “Should we expect that elections in which turnout is higher are ones in which we can expect Democrats to have done better?” The third question is the counterfactual: “If turnout were to have increased in some given election, would Democrats have done better?” We show the logical independence of the first two questions from one another and from the third, and argue that previous researchers have failed to recognize this logical independence – sometimes thinking they were answering question three when in fact they were answering either question one or question two. Reviewing previous research, we find that the answer to the first question once was YES but, for more recent elections at the presidential level, now appears to be NO, while, for congressional and legislative elections, the answer to the second question appears generally to be NO. However, the third question is essentially unanswerable absent an explicit model of why and how turnout can be expected to increase, and/or analyses of individual level panel data. Thus, the cross-sectional and pooled data analyses of previous research are of almost no value in addressing this third question.
