ABSTRACT

This qualitative study analyzes the activation of accountability mechanisms in public services and the changing dynamics between relevant actors. It remains unclear how accountability relationships emerge, when they are introduced, and under which circumstances administrative values are challenged over the course of administrative reforms. Our analysis of a Brazilian state prison system elucidates some of these elements by investigating a case in which an institutional crisis resulted in administrative reforms and new accountability dynamics. Our findings suggest that initiating accountability reforms before some services reach the level of severe crisis may be particularly difficult. We demonstrate that the development of accountability relationships is largely influenced by prominent actors capable of strategizing their actions in a collaborative fashion with other stakeholders. Additional layers of external regulation are also crucial to reduce the risks of political and regulatory capture, engage previously absent stakeholders, activate accountability mechanisms, and make reforms possible.  相似文献

For most of its history, Latin America has lived under authoritarian and elite rule where public decisions were often crafted in the shadows by cabinets and parliaments to the benefit of a small minority. Recently, the development of participatory political systems has brought some transparency to the policy-making process. Such scrutiny reveals evidence of the capture of aspects of policy-making by private interests that use obscure strategies to achieve their political goals. As a consequence, a widespread movement for regulating the role and tactics of interest groups emerged, which is seen as a necessary step to address the root causes of political corruption. This article provides an overview of efforts to regulate lobbying in Latin America. It explains attempts at regulation in four countries (Argentina, Brazil, Chile, and Peru), evaluates the level of success of these efforts, and assesses prospects for the future regarding reducing corruption through the instrument of lobby regulations. The authors argue that such regulations alone cannot eliminate political corruption. However, lobby regulations can contribute to increased transparency and aid in developing an anti-corruption culture. It will be shown that lobby laws in Latin America exhibit many of the problems long identified with similar regulations across western democracies. Copyright © 2012 John Wiley & Sons, Ltd.  相似文献

Solid-phase microextraction (SPME) is a relatively new solventless sample preparation technique that allows simultaneous sampling, extraction, pre-concentration, and introduction of analytes from a sample matrix in a single procedure. This methodology has been used for the analysis of several drugs of forensic toxicology interest including volatile compounds. This paper describes a methodology for analysis of ethanol and other volatile compounds using automatic headspace solid-phase microextraction (HS-SPME) and capillary gas chromatography in postmortem specimens. The methodology was initially developed using standard solutions of acetaldehyde, acetone, methanol, and ethanol. Isobutanol was used as internal standard. Postmortem samples of blood, urine, and vitreous humor were obtained during medico-legal autopsies. To date, there are no published paper regarding alcohol analysis in vitreous humor specimens using HS-SPME and limited literature analyzing blood and urine samples. HS-SPME analysis showed that, under optimized conditions, ethanol and isobutanol (internal standard) were well-separated from other volatile compounds such as acetaldehyde, acetone, and methanol considered to be potential interferents in ethanol analysis. The calibration curves for each volatile compound demonstrated good linearity throughout the concentration range from 0.001 to 1.0 g/dl and the detection limit of ethanol in the studied specimens was approximately 0.0001 g/dl.  相似文献

Facial reconstruction is a method that seeks to recreate a person's facial appearance from his/her skull. This technique can be the last resource used in a forensic investigation, when identification techniques such as DNA analysis, dental records, fingerprints and radiographic comparison cannot be used to identify a body or skeletal remains. To perform facial reconstruction, the data of facial soft tissue thickness are necessary. Scientific literature has described differences in the thickness of facial soft tissue between ethnic groups. There are different databases of soft tissue thickness published in the scientific literature. There are no literature records of facial reconstruction works carried out with data of soft tissues obtained from samples of Brazilian subjects. There are also no reports of digital forensic facial reconstruction performed in Brazil. There are two databases of soft tissue thickness published for the Brazilian population: one obtained from measurements performed in fresh cadavers (fresh cadavers' pattern), and another from measurements using magnetic resonance imaging (Magnetic Resonance pattern). This study aims to perform three different characterized digital forensic facial reconstructions (with hair, eyelashes and eyebrows) of a Brazilian subject (based on an international pattern and two Brazilian patterns for soft facial tissue thickness), and evaluate the digital forensic facial reconstructions comparing them to photos of the individual and other nine subjects. The DICOM data of the Computed Tomography (CT) donated by a volunteer were converted into stereolitography (STL) files and used for the creation of the digital facial reconstructions. Once the three reconstructions were performed, they were compared to photographs of the subject who had the face reconstructed and nine other subjects. Thirty examiners participated in this recognition process. The target subject was recognized by 26.67% of the examiners in the reconstruction performed with the Brazilian Magnetic Resonance Pattern, 23.33% in the reconstruction performed with the Brazilian Fresh Cadavers Pattern and 20.00% in the reconstruction performed with the International Pattern, in which the target-subject was the most recognized subject in the first two patterns. The rate of correct recognitions of the target subject indicate that the digital forensic facial reconstruction, conducted with parameters used in this study, may be a useful tool.  相似文献
