The article analyses the interaction between various forms of accountability on the basis of a case study of responses to the Federal Police of Argentina's practice of framing innocent victims. The failure of classic agencies of balance to establish accountability was compensated in this case by the creation of an ad hoc agency of oversight, an investigative commission established by the Attorney General, that interacted with social agents of accountability. The analysis points to the ambivalent role of the media in both supporting and exposing illegal police practices and shows that the cooperation between the commission and social actors was crucial to its success. 相似文献

Development of a GC-MS method for the simultaneous analysis of latent fingerprint components 总被引:1,自引:0,他引:1
Latent fingerprint residue is a complex mixture of organic and inorganic compounds. A full understanding of the composition of this mixture and how it changes after deposition is lacking. Three solvent systems were compared for the simultaneous extraction and derivatization with ethyl chloroformate of selected amino and fatty acids from a nonporous substrate (Mylar for subsequent analysis by gas chromatography-mass spectrometry. A solvent system comprised of sodium hydroxide, ethanol, and pyridine was found to be the most effective. This method was applied to the analysis of latent fingerprint residue deposited on Mylar and preliminary data are presented. Twelve amino acids (e.g., serine, glycine, and aspartic acid) and 10 fatty acids (e.g., tetradecanoic, hexadecanoic, and octadecanoic acids) were identified. The potential application of this method to further the understanding of latent fingerprint chemistry has been demonstrated. 相似文献

The increase in both automation and precision in the analysis of geological materials has had significant impact upon forensic investigations in the last 10 years. There is however, a fundamental philosophical difference between forensic and geological enquiry. This paper presents the results of forensic geoscientific investigations of three cases of wildlife crime. Two cases involve the analysis of soils recovered after incidents of illegal badger baiting in the United Kingdom. The third case involves the illegal importation of Eleonora's Falcon (Falco eleonorae) into the United Kingdom from the Mediterranean. All three cases utilise the analysis of soils by a variety of physical, chemical and biological techniques. These involve mineral and grain size analyses, cation and anion compositions, pH, organic content and pollen analysis. The independent analysis undertaken by specialists in each of these three main fields conclude firstly, that there is a significant similarity between sediments taken at the crime site at both badger setts and with sediments recovered from various spades, shovels and clothing belonging to suspects and secondly, that the soils analysed associated with the removal of the falcon eggs in the Mediterranean contained characteristics similar in many respects to the soils of the breeding areas of F. eleonorae on the cliffs of Mallorca. The use of these independent techniques in wildlife crime detection has great potential given the ubiquitous nature of soils and sediments found in association with wildlife sites. 相似文献

Previous research has established a relationship between Contraceptive Self-Efficacy (CSE), as measured by the 18-item CSE scale, and young women's contraceptive behavior (Bilodeau, Forget, and Tetreault, 1994; Heinrich, 1993; Levinson, 1986; Wright, 1992). In this paper, we continue to explore the scale and its relationship to contraceptive behavior with four diverse samples to establish generalizability and to set guidelines for use of the scale. A series of correlational analyses were conducted with each sample. A pattern of low correlations among CSE items across samples emerged, indicating that use of the total item set separately as the basis for CSE was warranted. Zero-order and partial correlations revealed which CSE items were correlated with contraceptive behavior as well as which items explained unique variance in contraceptive behavior for each sample. Regression analyses showed that CSE was significantly predictive of contraceptive behavior for all samples. These results are discussed in terms of scale properties and use in research and clinical settings. Educational implications are formulated as well. 相似文献
