Dawn H. Currie 《Critical Criminology》1990,1(2):77-96
Within the context of legal reform, the Battered Wife Movement has divided feminists on the question of criminal justice as
a desirable component of a feminist agenda. Thus it provides a good example of the dilemmas of developing a feminist theory
about the state as the basis for informed practice. In this paper, Currie overviews the way in which the BWM has been transformed
from a radical demand for the redistribution of social power into an expansion of current patriarchal institutions. As an
example of the institutionalization of feminist issues, however, she rejects explanations of this transformation as simply
ideological revision by the state. Rather, Currie notes that it occurs through and not against feminist discourse, meaning
that we must acknowledge theory as practice if we are to develop a truly subversive and liberatory discourse within feminist
scholarship. 相似文献

Deoxyribonucleic acid (DNA) typing of ribosomal ribonucleic acid (rRNA) genes was performed with a polymerase chain reaction (PCR) assay for species identification. A variable region of the 28S ribosomal RNA gene was amplified with primers complementary to flanking sequences phylogenetically well conserved. The products of twelve animal DNAs (human, Japanese monkey, dog, cattle, pig, cat, rabbit, mouse, rat, chicken, frog, and fish) were separated by polyacrylamide gel electrophoresis, each revealing a few bands ranging from 150 to 100 base pairs. The band patterns obtained from each DNA sample differed in number and size, which indicates the applicability of the method to species identification. Samples containing either as little as 1 pg of DNA or degraded DNA of 0.2 to 0.5 kb in length were able to give detectable bands. Postmortem human tissue DNAs were tested as an example. They showed a pattern identical to the human control one, which was distinct from those of the other animals examined. 相似文献

Policy analysis for the Congress is a timely subject. Several policy initiatives have emerged recently from the “first branch.” Others have demonstrated an independent capacity for analysis that is impressive by historical standards. This article introduces a practitioner symposium of three related works on policy analysis for Congress, with appropriate commentary by a distinguished veteran. It argues that because timing is crucial in the congressional policy process, anticipation and advance preparation are central to the effective use of analysis. The other articles illustrate the stages of advance preparation—of the policy analyst, the congressional environment, and the Member for voting—in the form of case studies. 相似文献

Threatening and otherwise inappropriate letters to members of the United States Congress 总被引:2,自引:0,他引:2
P E Dietz D B Matthews D A Martell T M Stewart D R Hrouda J Warren 《Journal of forensic sciences》1991,36(5):1445-1468
The authors examine the characteristics of threatening and otherwise inappropriate communications sent to members of the U.S. Congress by a sample of 86 subjects, 20 of whom threatened assassination. We quote excerpts from these letters and provide quantitative data on such variables as the volume, duration, form, and appearance of such communications; the enclosures; the subjects' perceived relationships to the recipients; the thematic content of the communications; and the messages and threats communicated. Comparisons between 43 subjects who pursued encounters with members of Congress and 43 who did not revealed 17 factors associated with such pursuit. In this population, threateners were significantly less likely to pursue an encounter than inappropriate letter writers who did not threaten, regardless of the type of threat or the harm threatened. Inappropriate letters to members of Congress are compared with those directed to Hollywood celebrities. Mentally disordered persons writing to public figures often mention and sometimes threaten public figures other than those to whom the letters are addressed, which raises important issues regarding notification of endangered third parties and the sharing of information among protective agencies. 相似文献

Bioaerosol data is often used in cases of building mold infestation alleging damage or adverse health effects upon occupants, despite the lack of consistent sampling and analytical protocols and numerical health-based standards. The most fundamental problem in these scenarios is defining a “significant” difference between a suspect indoor environment and the reference environment, regardless of the type of sampling and analysis utilized. Data interpretation focused upon differences in absolute numerical concentrations of fungi is subject to wide differences in expert opinion. On the other hand, an objective quantification of differences can be expressed in terms of probability and better meets criteria established in evidentiary rules. 相似文献

Der Begriff der Landeskultur umfasst alle Maßnahmen zur Verbesserung der land- und forstwirtschaftlichen Nutzung des Bodens einschließlich der Erhaltung der Kulturlandschaft. Landeskultur ist somit alles Planen und Handeln mit dem Ziel, die Umwelt als gegebenes Naturraumpotential, insbesondere Wasser, Boden, Luft und die dazugehörigen Natur-, Kultur- und Sachgüter optimal zu erhalten, gestalten und rationell zu nutzen sowie dieses Potential mit bestmöglicher Qualität als natürliche und kulturelle Lebensgrundlage für die Allgemeinheit nachhaltig zu sichern. Landeskultur dient somit auch der Belebung und Werterhöhung der gebauten und gepflanzten Umwelt. Dies schließt auch und gerade die kulturelle Seite einschließlich Kulturlandschaften mit ein. Dabei ist es bis zur Überprüfung durch das BVerfG noch hinnehmbar, dass der Begriff „Landeskultur“ in Art. 89 Abs. 3 GG wegen der Mischkompetenz von Bund und Land vom BVerwG enger ausgelegt wird als in anderen Rechtsvorschriften. 相似文献

Toxicologic findings in the USS Iowa disaster. 总被引:5,自引:0,他引:5
The toxicologic results from the 47 victims of the explosion on the USS Iowa are presented. Good correlation between carboxyhemoglobin saturations and cause of death was found. There were no correlations between blood cyanide concentrations and causes of death. Volatile analysis suggested postmortem ethanol production rather than antemortem ethanol ingestion. No drugs except nicotine were detected in any of the victims. 相似文献
