The rise of “new” transnational governance has intensified debates about a lack of accountability in global politics. Reviewing the mechanisms through which transparency can foster accountability beyond the state, this article explores the determinants of information disclosure in the field of transnational sustainability governance. Examining the institutional design of 113 voluntary sustainability programs, we find a positive correlation between the involvement of public actors and information disclosure. In contrast, the role of civil society is more ambiguous. There is no statistical support for arguments linking non‐governmental organization participation to increased transparency. At the same time, our analysis reveals a robust correlation between civil society‐led metagovernance and information disclosure. Moreover, we find that crowding has a negative effect on transparency, whereas normative peer pressures have no influence. At a broader level, the analysis reveals a lack of “deep transparency” among transnational sustainability governors. This limits the scope for transparency‐induced accountability in this policy domain.  相似文献

This paper examines how far the workplace inspection program established under the 2013 Accord on Fire and Building Safety has served to improve safety in Bangladesh garment factories, and the extent to which its operation has been influenced by factors that the literature suggests are important in shaping the outcomes of private regulatory initiatives. The findings suggest that such regulation can generate positive outcomes, even in the absence of strong public regulatory support. They also caution against discounting the role of compliance‐based enforcement strategies, while highlighting the importance of their adequate resourcing and transparency. Some support is also offered for the argument that such regulatory initiatives could directly influence the market dynamics that shape supplier working conditions.  相似文献

The unusual appearance of crystalline fat structures was observed during the postmortem examination of a motor vehicle accident victim. The crystal structures were characterized using Fourier transform infrared spectroscopy and x-ray diffractometry. The structures were found to be made of triacylglycerols, a dominant lipid structure found in human adipose tissue, capable of forming various polymorphic structures. The morphology of the crystalline material was found using both techniques to be predominantly the beta' form of triacylglycerols. The accelerated growth of such triacylglycerol morphology has been observed as a result of shear stresses in other studies involving edible fats. As a result of the findings of this study, it is proposed that increased shear forces may be responsible for the formation of the unusual fat structure found in the victim. An understanding of the effect of forces on the structure of body fat in high-impact collisions can potentially assist in verifying a high-velocity impact.  相似文献

Forensic application of carbon isotope ratio measurements of honey and honey protein to investigate the degree of adulteration with high fructose corn syrup or other C4 plant sugars is well established. These measurements must use methods that exhibit suitable performance criteria, particularly with regard to measurement uncertainty and traceability – low levels of adulteration can only be detected by methods that result in suitably small measurement uncertainties such that differences of 1‰ or less can be reliably detected. Inter-laboratory exercises are invaluable to assess the state-of-the art of measurement capabilities of laboratories necessary to achieve such performance criteria. National and designated metrology institutes from a number of countries recently participated in an inter-laboratory assessment (CCQM-K140) of stable carbon isotope ratio determination of bulk honey. The same sample material was distributed to a number of forensic isotope analysis laboratories that could not participate directly in the metrological comparison. The results from these studies have demonstrated that the majority of participants provided isotope delta values with acceptable performance metrics; that all participants ensured traceability of their results; and that where measurement uncertainties were reported; these were fit-for-purpose. A number of the forensic laboratories only reported precision rather than full estimates of measurement uncertainty and this was the major cause of the few instances of questionable performance metrics. Reporting of standard deviations in place of measurement uncertainties is common practice outside metrology institutes and the implications for interpretations of small differences in isotopic compositions are discussed. The results have also highlighted a number of considerations that are useful for organisers of similar inter-laboratory studies in the future.  相似文献

This study used a mixed-methods approach to investigate stigma experiences and self-concepts of individuals with both mental illness and criminal histories. The full sample of participants completed self-report measures of self-concept related to mental illness, race, and criminal history, and a brief qualitative self-concept measure. A subsample of participants completed semi-structured interviews, which were analyzed for content domains. Analyses suggested that several aspects of self-concept related to responses on stigma measures. Participants who identified their own styles of acting, feeling, and thinking tended to exhibit less mental illness self-stigma. Qualitative interview findings suggested that the majority of participants described stigma experiences related to mental illness, race, and criminal history, and these stigmatized identities negatively influenced one another. Conclusions review how stigmatized identities can intersect in powerful ways for individuals with mental illness and histories of criminal offending, and discuss implications for future research and clinical practice.  相似文献

Psychologists and other professionals are often appointed by the courts to assist families in resolving post-separation disputes and to assist judges in making orders on behalf of the best interests of the child(ren). Although these evaluations provide valuable information to the court, they require assessing areas of human behavior that are imprecisely defined or lacking professional consensus. As parents separate, their disputes may become more challenging, and they may act in uncharacteristic and unpredictable ways. Families that cannot solve their own challenges outside of court often show high levels of conflict and/or have issues that are extremely complex, including domestic violence allegations, resist-refuse family dynamics, and relocation requests. Evaluators and judges, being human, tend to oversimplify complex issues due to the limitations of the human brain. Evaluators are subject to cognitive biases that result from the use of mental heuristics, leading to shortcuts and errors in their reasoning and judgment. Other biases, such as implicit and explicit cultural biases, often influence evaluators' reasoning and conclusions. This article explores various biases that affect and potentially diminish the quality of an evaluator's work. We conclude by addressing “de-biasing” strategies that can reduce, but not negate, the risks associated with such biases.  相似文献
