Examining the oil and gas industry in the Russian Arctic, this article investigates the gap between corporate social responsibility (CSR) as articulated in corporate offices and implemented at the local level. In Russia, global CSR norms interact with weak formal institutions and the strong informal expectations of state officials and local communities that companies bear responsibility for welfare and infrastructure. As a result, the concept of citizens as ‘stakeholders’ is underdeveloped. Instead, local residents remain subjects within a neo-paternalist system of governance that mimics some elements of the Soviet past. Compensation for damages to indigenous peoples has blurred legal obligations and the voluntary nature of CSR. However, the CSR in the region is constantly developing and formal methods of compensation may assist in clarifying the scope and practice of CSR.  相似文献

In this paper, I look into personal and political entanglements in Rosa Luxemburg’s letters and essays revolving around questions and problems of the revolution. The analysis is informed by Hannah Arendt’s theorisation of revolutions in modernity, as well as her reading of narratives within the political. What is intriguing about the Luxemburg/Arendt encounter is the fact that although both theorists consciously refused to connect themselves with feminist ideas and movements of their times and geographies, their writings have inspired a rich body of feminist theorisations of the political. What I argue is that Luxemburg’s ideas and lived experiences of the revolution largely inspired Arendt’s theorisation of the revolution as a political phenomenon in the pursuit of freedom, and are opening up new vistas in our understanding of gendered dynamics in historical and contemporary revolutionary events.  相似文献

Intravascular lymphoma (IVL) is a rare subtype of extranodal lymphomas that is characterized by the selective growth of neoplastic cells within the lumen of small vessels. Authors document the case of an unexpected death caused by an undiagnosed intravascular large B-cell lymphoma with multi-organ involvement, which had initially manifested as an infection and then as an unclarified central nervous system pathology. Histological examination showed a diffuse intravascular large B-cell brain lymphoma with prominent cerebral involvement. The relevance of the case report reveals the importance of an autopsy of an extremely rare and threatening pathology that in most cases is diagnosed only postmortem. As a result, the role of the forensic pathologist becomes particularly important. When specifically performing an in-depth autopsy evaluation with a specific histologic analysis, it is possible to identify the intravascular lymphoma and declare a more accurate cause of death.  相似文献

Many studies in the literature have highlighted the utility of virtual 3D databanks as a substitute for real skeletal collections and the important application of radiological records in personal identification. However, none have investigated the accuracy of virtual material compared to skeletal remains in nonmetric variant analysis using 3D models. The present study investigates the accuracy of 20 computed tomography (CT) 3D reconstruction models compared to the real crania, focusing on the quality of the reproduction of the real crania and the possibility to detect 29 dental/cranial morphological variations in 3D images. An interobserver analysis was performed to evaluate trait identification, number, position, and shape. Results demonstrate a false bone loss in 3D models in some cranial regions, specifically the maxillary and occipital bones in 85% and 20% of the samples. Additional analyses revealed several difficulties in the detection of cranial nonmetric traits in 3D models, resulting in incorrect identification in circa 70% of the traits. In particular, pitfalls included the detection of erroneous position, error in presence/absence rates, in number, and in shape. The lowest percentages of correct evaluations were found in traits localized in the lateral side of the cranium and for the infraorbital suture, mastoid foramen, and crenulation. The present study highlights important pitfalls in CT scan when compared with the real crania for nonmetric analysis. This may have crucial consequences in cases where 3D databanks are used as a source of reference population data for nonmetric traits and pathologies and during bone-CT comparisons for identification purposes.  相似文献

In recent years, Spanish local governments have come under increasing pressure to accommodate severe economic restrictions while maintaining their provision of local public services. We analyse overall cost efficiency in Spanish local governments during the period of the economic crisis (2008–2013), under four different non-parametric methodologies. Moreover, given how problematic it is to precisely define what municipalities do, we compare three different output models with various measures of quantity as well as quality. Results suggest that Spanish local government efficiency improved over the period 2008–2013 since budget expenditures (inputs) fell while local public services and facilities (outputs) were maintained. We also find evidence of the possible implications of service quality when measuring municipalities’ efficiency, and of structural differences in the average efficiency between municipalities located in different Spanish regions. Finally, our results confirm that the level and variation of efficiency scores are affected by the approach taken.  相似文献
