This article reports a comparative study of the Environmental Regulatory Agencies in Norway, Denmark and Finland. Increasingly and relatively independently these agencies are taking part in transnational networks in the European Union involving the European Commission. An informal penetration, fuelled by faster electronic technology, is taking place between the European Commission and the regulatory agencies, largely outside the control of the domestic politico-administrative leadership. Changes in the character of the states' public administrations serve as an important background for these developments, a distinctive feature being the 'agencification' of the administrative apparatus during the last decades. Due to their relative autonomy, the national regulatory agencies are well placed to work 'double-hatted' in the sense that they interact directly with the European Commission at the same time as they perform traditional tasks as agents of national ministries. This development may challenge the image of integrated administrative apparatus and the notion of transparent and democratic governance. 相似文献

This paper employs data from the Bangladesh Demographic and Health Survey (2004) to explore how women’s empowerment is related to partner’s attitudes, participation in microcredit programmes and a set of other socio-economic factors. We use a structural equation model with categorical observed variables. We get that participation in microcredit programmes has a positive impact on both the empowerment’s dimensions considered, while partner’s attitudes effect is weaker, proving that gender community norms are likely to be rooted in women’s minds regardless of the partners’ perceptions of women’s status. 相似文献

Food production has been changing significantly in recent years as a result of climate change and of growing demand for food. This article aims to understand the link between food security and international security in the context of climate change, applying a systematic and qualitative analysis of the literature using the bibliometric method. This research observes that climate change tends to affect agricultural productivity, exposing societies to risk and the need for migration. However, good governance, together with international cooperation, can reduce the hazards of food insecurity, strengthening ties between countries and stimulating a fairer and more inclusive form of international trade. 相似文献

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

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

The Inventory of Problems-29 (IOP-29; Viglione, Giromini, & Landis, Journal of Personality Assessment, 99(5), 534–544, 2017) is a 29-item, recently published, self-administered test aimed at assessing the credibility of various symptom presentations. Although available research strongly supports the use of this symptom validity test in malingering-related contexts, to date, only few studies have analyzed data from real-life forensic evaluations. To fill this gap and explore ecological and convergent validity, the current study analyzed data from 74 court-ordered evaluations aimed at establishing the possible presence of psychological injury. Such evaluations are high-stakes situations in which exaggeration or malingering occur relatively often. We used a research-supported and popular symptom validity test, i.e., the Structured Inventory of Malingered Symptomatology (SIMS; Smith & Burger, Journal of the American Academy on Psychiatry and Law, 25:180–183, 1997), as our criterion variable. The IOP-29 produced excellent area under the curve (AUC) values of .98 with a recommended SIMS total score cutoff (≥ 17) and .99 when eliminating too-close-to-classify cases (Rogers & Bender, 2018) and very large Cohen’s d effect sizes of 2.98 and 3.59, respectively. Crucially, when implementing established cut scores from previous research, the IOP-29 yielded very high specificity and sensitivity rates, and the predictions from the two tests were strikingly similar. Taken together, these findings support the strong convergent validity of the IOP-29 and its utility in applied clinical and forensic settings. 相似文献
