This paper investigates informal mechanisms of knowledge transfer (KT) from a local university to entrepreneurial teams comprising students and recent graduates. While the extant literature on university-industry KT largely focuses on formal mechanisms aimed at stimulating entrepreneurial initiatives in high-tech (HT) sectors, it overlooks the effect of university-industry KT on nascent entrepreneurship in low-medium tech (LMT) sectors. To fill this gap in the literature, we carry out a mixed-method analysis that exploits a dataset of 154 new business ideas (and 535 team members) presented at a business plan competition in Rimini from 2010 to 2017. Our findings highlight a robust relationship between educational field and the R&D intensity of entrepreneurial projects: students take advantage of the knowledge acquired at university to develop entrepreneurial projects with higher technological content than those planned by non-graduates. Furthermore, the empirical evidence shows that the local university nurtures the formation of ties among students and recent graduates enrolled in the same courses and fosters their efforts to launch new ventures. Finally, the qualitative analysis identifies relevant and non-traditional mechanisms of KT that are being exploited by nascent entrepreneurs to develop their business ideas in the LMT and HT sectors.

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

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

Postmortem magnetic resonance imaging (MRI) is rarely used for the radiologic assessment of gunshot injuries, although it has clear advantages over postmortem computed tomography (CT) with regard to the imaging of soft tissue injuries. Another benefit in using MRI is that lodged projectiles composed of nonferromagnetic material such as lead present only marginal metal artifacts compared with severe artifacts on CT. This case report presents CT and MRI findings in a case with two gunshot wounds to the neck: a perforating wound and a nonperforating wound with a lead bullet lodged in the cervical spine. The decedent underwent CT and MRI before the scheduled autopsy. A ring of radiopaque material under the dermis in the fatty tissue was identified at both entrance wounds on CT, which was indicative of contact shots. The perforating gunshot was clearly indicated on CT by bullet fragments along the wound channel through the perforated 6th cervical vertebra and the fractured cricoid cartilage at the exit wound. The second trajectory, however, was only assumed based on the presence of gunshot residues at the entrance wound and the position of the lodged bullet. The radiologic assessment was severely impeded by the metal artifacts on CT. Barely noticeable metal artifacts on MRI allowed for clear visualization of the soft tissue injuries and the ruptured medulla oblongata. Only MRI clarified the soft tissue injuries of the brainstem noninvasively, which could provide specific and graphic information on the rapidity of death and the incapacitation of the victim.  相似文献
