Indigenous peoples’ right to prior consultation and to informed consent represents the basis of the new global model shaping state–indigenous relations. Consultation processes promise to enable indigenous people to determine their own development and are especially promoted when extraction projects with significant socio-environmental impacts are planned on indigenous lands. In this article we draw on debates on participatory development in order to analyse the first state-led consultations in Bolivia’s and Peru’s hydrocarbon sectors (2007–14). The analysis shows that effective participation has been limited by (1) an absence of indigenous ownership of the processes; (2) indigenous groups’ difficulties defending or even articulating their own visions and demands; and (3) limited or very general outcomes. The study identifies real-life challenges, such as power asymmetries, a ‘communication hurdle’ and appropriate timing – as well as simplistic assumptions underlying the consultation approach – that account for the unfulfilled promises of this new model.  相似文献

Scholars' criticism of transparency in public–private partnerships (PPPs) often focuses on ‘external’ transparency, that is, the extent to which internal information is visible to the outside world. However, to achieve external transparency, internal transparency – the availability and inferability of information for the public procurer and the private party – is crucial. In this article we analyse input, process, and output transparency from three different perspectives (institutional, cognitive, and strategic) in four PPPs in the Netherlands. We conclude that input transparency is high, but process and output transparency less so. Moreover, output transparency has gained importance in PPPs. Whether this is problematic depends on the PPPs' institutional environment. In some partnerships the desired output is uncontested and predetermined by clear standards in the institutional environment, whereas other PPPs deal with contested output norms, decreasing the partnerships' transparency. These results nuance the current debate on the lack of transparency in PPPs.  相似文献

This article makes a further contribution to opening the ‘black box’ of micropractices in ministry–agency relationships. We argue that the mechanisms that come into play in the course of institutionalizing agencification reforms – such as renegotiating mutual roles and rules in ministry–agency interactions – are only poorly covered in the existing literature. To adequately address the negotiated and contingent nature of de facto agency autonomy and political control, we develop an interpretive approach based on the concept of ‘boundary work’. The empirical focus is on ministry–agency interactions at the science–policy nexus in the contested policy field of food safety. By studying actors' stories about the institutionalization processes following the fundamental reorganization of the German food safety administration in the wake of the BSE crisis from a longitudinal perspective, we show how actors manage boundary conflicts via increasingly differentiated backstage coordination.  相似文献

This article discusses from the perspective of democratic theory an innovative proposal for the selection of constitutional, supreme court, or federal judges that aims at combining the values of expertise and political independence. It consists in combining a certification process – selecting a pool of properly qualified candidates – with a random selection among this pool. We argue that such selection procedure would better respect the separation of powers and the specific legitimacy of courts, and we champion this two‐stage mechanism vis‐à‐vis other, more traditionally employed, selection procedures. We then deal with a diversity of objections to our proposal and conclude by taking stock of both its virtues and limitations.  相似文献

Microbial communities have potential evidential utility for forensic applications. However, bioinformatic analysis of high-throughput sequencing data varies widely among laboratories. These differences can potentially affect microbial community composition and downstream analyses. To illustrate the importance of standardizing methodology, we compared analyses of postmortem microbiome samples using several bioinformatic pipelines, varying minimum library size or minimum number of sequences per sample, and sample size. Using the same input sequence data, we found that three open-source bioinformatic pipelines, MG-RAST, mothur, and QIIME2, had significant differences in relative abundance, alpha-diversity, and beta-diversity, despite the same input data. Increasing minimum library size and sample size increased the number of low-abundant and infrequent taxa detected. Our results show that bioinformatic pipeline and parameter choice affect results in important ways. Given the growing potential application of forensic microbiology to the criminal justice system, continued research on standardizing computational methodology will be important for downstream applications.  相似文献

Novel psychoactive substances (NPS) are synthetic drugs that pose serious public health and safety concerns. A multitude of NPS have been identified in the United States, often implicated in forensic investigations. The most common and effective manner for identifying NPS is by use of mass spectrometry and the true utility lies within nontargeted acquisition techniques. During this study, a liquid chromatography quadrupole time-of-flight mass spectrometry (LC-QTOF-MS) assay was developed, validated, and implemented for forensic toxicology testing. A SCIEX TripleTOF™ 5600 + with SWATH® acquisition was used. Resulting data were compared against an extensive library database containing more than 800 compounds. The LC-QTOF-MS assay was applied to the reanalysis of biological sample extracts to discover emergent NPS. More than 3,000 sample extracts were analyzed, and more than 20 emerging NPS were detected for the first time. Among these were isopropyl-U-47700, 3,4-methylenedioxy-U-47700, fluorofuranylfentanyl, N-methyl norfentanyl, 2F-deschloroketamine, 3,4-methylenedioxy-alpha-PHP, eutylone, and N-ethyl hexedrone.  相似文献

Examination of the female external genitalia to assess for sexual abuse is performed in living individuals, and the interpretation of the findings is based on evidence-based studies. However, in the deceased, no such studies are available, and postmortem changes could present as suspicious findings that can be mistaken for trauma. Patches of discoloration in the hymen were reported previously in one case as hypostasis (i.e., livor and lividity), and based on this finding, it was listed as a finding that is not associated with trauma. This was a retrospective study that was conducted in the Center of Forensic and Legal Medicine in Dammam, Saudi Arabia over a 4-year period. The study included 30 deceased women in whom photographic documentation of their external genitalia was assessed for postmortem changes. The postmortem interval ranged from less than 24 h to more than 100 days, and the ages of these deceased women were in the 20–40 year-old age group. In cases where the hymen, vagina, and/or fossa navicularis were clearly visible, none of these areas showed any hypostatic discoloration. A comparison between antemortem and postmortem appearance of the hymen in one case clearly showed the absence of hypostatic changes in the hymen. In conclusion, any discoloration of the external genitalia that is detected in a female decedent requires serious consideration.  相似文献
