Researchers are currently seeking antecedents of psychopathy among children and adolescents. Instruments developed for this purpose are likely to be used in the future in ways that may have serious implications for youths in delinquency and criminal cases. In this regard, and because the concept and measurement of psychopathy have been developed in reference to adults, there is reason to be concerned about potential developmental sources of false positives when measuring psychopathic traits in juvenile offenders. We provide the basis for our concern, as well as standards regarding the types of research evidence that should be provided before psychopathy measures are accepted for use in juvenile forensic assessments. 相似文献

Glycated hemoglobin (HbA(1c)) has been demonstrated to be a useful marker for long-term glucose control in diabetes. This parameter characterizes each non-enzymatic fixation of glucose on hemoglobin. It is a useful test in addition to periodic glycemia controls since it reflects the mean glycemia of the past 60 days. We studied the conservation of HbA(1c) at 4 degrees C as a function of time with different anti-coagulants and preservatives (3, 6 months, 1 year). A total of 106 tests were performed using the high performance liquid chromatography (HPLC) method dedicated to the semi-automatic analysis of HbA(1c) (Bio-Rad) and we applied the method in forensic cases. Conservation at 4 degrees C was good for as long as 3 months in blood samples collected with fluoride and 6 months in samples collected in a dry or in a heparinized tube. In non-diabetic subjects, HbA(1c) reference values obtained from forensic samples were identical to those of living controls (3.5-6.25% of total hemoglobin). All positive HbA(1c) results were confirmed by a medical evaluation. This method was successfully applied to five forensic cases. In cases of increased acetonemia, acetone or isopropanol are easily measured. However, in some unexplained post-mortem circumstances, increased HbA(1c) permits to differentiate alcoholic or starvation ketoacidosis from the diabetic cases. Glycated hemoglobin should, therefore, be considered the forensic marker of choice in the post-mortem diagnosis of a diabetic disorder and demonstrates its usefulness in post-mortem validation. 相似文献

Authoritarian Attitudes, Democracy, and Policy Preferences among Latin American Elites 总被引:1,自引:0,他引:1

This article examines the prevalence and consequences of authoritarian attitudes among elites in Argentina, Brazil, Chile, Colombia, Mexico, and Venezuela. We focus on the connection between antidemocratic elite attitudes and support for democracy; the causes and effects of authoritarian attitudes among elites and their implications for authoritarianism; and the impact of authoritarian attitudes beyond social policy preferences to other policy areas that have indirect implications for order. Contrary to some of the literature, we find that antidemocratic attitudes affect elites' support for democracy. Our analysis also speaks to the debate on the origins of authoritarianism. Much of the evidence supports Altemeyer's notion that perceived threat raises levels of authoritarianism, rather than Feldman's contention that threat strengthens the influence of authoritarian attitudes. Finally, we demonstrate that there is a broader influence of authoritarian attitudes on economic policy preferences, but only where those policies appear to have implications for social order. 相似文献

This paper examines a number of demographic aspects in congressional districts and states that played important roles in a series of Congressional votes on environmental issues in 2000. These characteristics include urbanization or population density, education, income, race, and employment. Our findings are mixed. While we find some evidence (at least in Senate votes) that population density is a positive predictor of “pro-environment” votes, we also find that things commensurate with the Environmental Kuznets Curve such as income, education, and lifestyle also play an important role in environmental voting. 相似文献

Scholars and practitioners within the U.S. education system have focused considerable attention on developing new programs aimed at raising educational achievement for disadvantaged students. New programs are only one way to improve student performance, however; recent work in public administration suggests that public management and implementation practices might also have a large impact on student performance. Existing research shows that managerial networking, managerial quality, and effective personnel management can significantly improve the quality of the education received by disadvantaged students. Additional work highlights the contribution of representative bureaucracy. Because these research agendas have targeted the public administration literature rather than the education policy literature, this article seeks to bring this research back to education policy. Using data from several hundred Texas public school districts, spanning 1995 to 2002, and focusing on disadvantaged student performance (Latinos, blacks, and low‐income students), this article illustrates how both management and processes to enhance the representativeness of teaching faculty produce benefits for disadvantaged students. 相似文献

In the present article, we empirically analyse a series of competing hypothesis that try to account for the considerable disparity in the tax burden between Swiss cantons. Three hypotheses focus on differences in spending levels: The first explains differences in the tax burden with differences in citizens' demand for government services. The second emphasizes the differences in efficiency between cantonal administrations, whereas the third insists on the more or less easy access to cantonal instruments of direct democracy. However, when confronted to the data, none of these three expenditure‐based hypotheses are confirmed by our cross‐sectional estimations. On the contrary, our regressions lend support to the hypotheses which highlights the differences in tax revenues between cantons. These results suggest that it is not differences in government spending which account for the disparity in cantonal tax levels, but differences in the cantonal endowment with resources. This indicates that some financial equalization on the cantonal level might strengthen the equity of Switzerland's tax system. 相似文献
