This study probes the interconnections among distrust of government, the historical context, and public support for the death penalty in the United States with survey data for area-identified samples of white and black respondents. Multilevel statistical analyses indicate contrary effects of government distrust on support for the death penalty for blacks and whites, fostering death penalty support among whites and diminishing it among blacks. In addition, we find that the presence of a "vigilante tradition," as indicated by a history of lynching, promotes death penalty support among whites but not blacks. Finally, contrary to Zimring's argument in The Contradictions of Capital Punishment , we find no evidence that vigilantism moderates the influence of government distrust on support for the death penalty, for either whites or blacks. Our analyses highlight the continuing influence of historical context as well as contemporary conditions in the formation of public attitudes toward criminal punishment, and they underscore the importance of attending to racial differences in the analysis of punitive attitudes.  相似文献

We report a case of rapid death from thrombotic thrombocytopaenic purpura (TTP) in a young pregnant lady who developed full blown symptoms soon after caesarean section. Extensive intramyocardial confluent haemorrhages and widespread microthrombi in heart, brain, adrenals and kidney were found at autopsy. Thrombotic thrombocytopaenic purpura is an uncommon condition, which carries a high fatality rate if untreated. Awareness of this syndrome together with its high risk of sudden death underlines the importance of rapid diagnosis and treatment.  相似文献

The polymerase chain reaction (PCR) method of specific gene amplification was used in casework to synthesize millions of copies of the polymorphic second exon of the human leukocyte antigen (HLA)-DQ alpha (or DQA1) locus from a variety of evidence samples. The HLA-DQ alpha allelic variants in the amplified deoxyribonucleic acid (DNA) were determined in a rapid non-radioactive test by hybridization to sequence-specific oligonucleotide probes in both the dot-blot and reverse dot-blot formats. This genetic typing system has been subjected to blind proficiency testing; the performance of this test in the analysis of experimentally mixed samples was also evaluated. As of August 1990, over 250 cases have been tested and more than 2000 individual evidence (bloodstains, semen stains, individual hairs, bone fragments, and tissue sections) and reference samples have been analyzed. The first 198 of these cases are summarized in this paper; in 65% of the cases with conclusive results a suspect was included, and in 35%, all suspects were excluded. Individual cases as well as some of the general issues relating to forensic science analysis and this genetic typing system are discussed. The high rate of exclusion reported here combined with the ability of PCR to type old evidence samples suggests the relevance of this genetic test for postconviction review; two cases in which the convicted suspect was excluded are discussed.  相似文献
