This article reviews two approaches to the study of economic restructuring which focus on commodity-specific dynamics of change. The first is the global commodity chain (GCC) approach, which has been developed primarily for the analysis of industrial commodities.The second is the francophone filière tradition, which has been applied mostly to agricultural commodities originating from former French colonies. The article finds that the GCC approach has a more coherent framework than the filière approach, although it is still far from constituting a fully fledged 'theory'. The authors provide a number of suggestions for improving some of its key concepts. They also suggest that the GCC approach can be enriched by some of the insights gained in filière work, especially in terms of improving historical coverage and depth, enlarging the analysis to agricultural commodities, better handling of regulation issues, and including quality convention issues in analysing commodity chain structure and restructuring. 相似文献

Forensic entomology is a branch of forensic science in which insects are used as evidence in legal investigations relating to humans, domestic animals and wildlife. One of the theoretical pillars on which the discipline is based concerns the fact that flies colonize a body after death. However in cases of myiasis, maggots are present before death, with consequences in the correct estimation of the minimum postmortem interval (mPMI). We report here the case of a woman, largely colonized by fly larvae, who has lain alive in her garden for four days prior to being rescued. Larvae were found on the conjunctivae, the bronchi, the rectum and vagina. The woman's death, two months later, was caused by tetanus. The consequences of myiasis on mPMI estimation are here discussed. In fact, despite she was still alive larvae, indicated and estimated age of 1.5–2.5 days, based on environmental and body temperature. 相似文献

The emerging relationships connecting organizations are the condition on which innovation is founded nowadays, so it is pivotal to achieve a vaster comprehension of the phenomenon through the exploitation of new dynamics and the exploration of new trajectories. In line with the Quadruple Helix (QE) approach, it seems reasonable to expect that the different environments in which firms operate would highlight the expectations of the various market governance systems, which firms must comply with in order to gain social legitimacy and improve their capacity for survival. To determine whether the Quadruple Helix model has an effect on the firms’ profitability, the authors employed the classification analysis method (Classification And Regression Trees). The sample is composed by 4215 manufacturing firms located in science parks. In our empirical model, the variable “citizen” classifies businesses with high Return On Investment in the best way. This shows that in science parks “the fourth helix” (citizen) has an important role in classifying the firms with the highest performance. Moreover, the majority of firms that attribute high importance to the collaboration with private financial institutions in order to finance innovations have a high ROI. In addition, firms with high economic performance in the model of the quadruple helix generate product innovation. 相似文献

Abstract: In Italy, the “silent‐consent” principle of donor’s willingness regulates organ donation for postmortem transplantation, but civil incompetence excludes it. We investigated decisional capacity for organ donation for transplantation of 30 controls and 30 nonincompetent patients with schizophrenia as related to clinical symptoms, cognition, and functioning. Assessments were carried out through the Competence for Donation Assessment Scale (CDAS), Brief Psychiatric Rating Scale (BPRS), Scale for the Assessment of Positive Symptoms (SAPS), Scale for the Assessment of Negative Symptoms, Life Skills Profile (LSP), Raven’s Colored Progressive Matrices (RCPM), Wisconsin Card Sorting Test, Rey RI, Rey RD, and Visual Search. Patients and controls differed on the CDAS Understanding and Choice Expression areas. Patients showed significant inverse bivariate correlations between CDAS Understanding and scores on total BPRS, LSP self‐care scale, and RCPM cognitive test. Our results show that decisional capacity for participating in research does not predict decisional capacity for postmortem organ donation in patients with schizophrenic or schizoaffective psychosis; hence, before judging consent for donation, patients must be provided with enhanced information to better understand this delicate issue. 相似文献

Abstract: Acute respiratory distress syndrome (ARDS) is a severe lung disease characterized by inflammation of the lung parenchyma leading to impaired gas exchange. This condition is often lethal, usually requiring mechanical ventilation and admission to an intensive care unit. We present two fatal cases of hidden pneumonia in young people and discuss the pathophysiological mechanism of ARDS with reference to the histological pattern. A complete forensic approach by means of autopsy and histological, immunohistochemical, and microbiological, examination was carried out. In both cases the cause of death was cardio‐respiratory failure following an acute bilateral pneumonia with diffuse alveolar damage and ARDS associated with sepsis and disseminated intravascular coagulation. Our cases suggest on one side the importance of an early diagnosis to avoid unexpected death while on the other that the diagnosis of ARDS has to be confirmed on the basis of a careful postmortem examination and a complete microscopy and microbiological study. 相似文献

This paper investigates the dynamics of a sample of 131 science-based entrepreneurial firms (SBEFs), selected out of 500 innovative
small and medium enterprises (SMEs) that went public in Europe in the period 1995–2003. We found that the market for control
of these firms was active, with most of our sample firms being acquired after their Initial Public Offering (IPO), usually
by companies operating within the same industry. Floated SBEFs showed a higher propensity to be acquired than independent
firms; this distinction persisted after controlling for intellectual capital and other possible determinants. While university
affiliation enhanced attractiveness in the eyes of other companies, it negatively affected the propensity for acquisition.
We argue that university-based firms do contribute to the technology transfer process, as evidenced by the widespread interest
of the business world in investing in these firms. The creation of a SBEF is a first step in the process of commercial exploitation
of university-research, while the subsequent step of going public is a sign of the success of this entrepreneurial venture.
The take-over of SBEFs may be a final outcome of the process of knowledge diffusion. 相似文献
