This article based, on 38 in-depth interviews with Rotterdam cocaine retail dealers, aims to present a clearer picture of how cocaine supply lines in the Netherlands are organized in order to fine-tune policy with respect to crime, public order and safety on the different trade levels. On the retail level the market for cocaine is strictly separated in a market for crack cocaine versus a market for powder cocaine. The crack dealers are often hard drug users themselves living in relatively poor circumstances. Although dealing cocaine is their main activity, they tend to be involved in other activities related to the drug scene, e.g. smuggling cocaine via Amsterdam airport. The cocaine distribution line for supply on the local market is seldom more than two steps. Because the supply for the Rotterdam cocaine retailers comes mainly from small-scale imports, successful police operations against large-scale imports of cocaine will have little influence on the local cocaine supply in the Netherlands.  相似文献

The authors describe a case of sellar fracture followed by sudden death. The victim was involved in a wrangle. The autopsy revealed facial damage and sellar fracture and no evidence of cerebral damage, except for a mild subarachnoid hemorrhage in the left parietotemporal regions and undersurface of both frontal lobes. Sellar fracture is a rare and severe entity, associated with serious complications, which is frequently diagnosed postmortem. In any case, death is rarely a direct consequence of the sellar fracture itself and is usually considered to be the result of associated cerebral trauma. This case prompted us to screen the literature on sellar fracture to gain a better understanding of the mechanism of death.  相似文献

In the archeological site of the early Christian Episcopal complex of Saint Peter, in Canosa di Puglia (Bari, Italy), during the operations of archaeological excavations, tombs were discovered. They were dated between the sixth and seventh centuries ad with carbon 14 methodology. Five skeletons were found in the 5 tombs: 28A: male individual, 43 years old. The height was 170 cm; the biomass was 65.7 kg. The analysis of the bones indicated several noteworthy pathologies, such as a number of hypoplasia lines of the enamel, the presence of Schmorl hernias on the first 2 lumbar vertebrae, and the outcome of subacromial impingement syndrome. 28E was a male individual, with a biologic age of death of between 44 and 60 years. The height was 177 cm. He had a posttraumatic fracture callus of the medial third of the clavicle, with an oblique fracture rima. 29B was a female individual, 44-49 years old. The height was 158.8 cm; the biomass was 64.8 kg. There was Wells bursitis on the ischial tuberosity on both sides. 29E was a male individual, 45-50 years old. The height was 169.47 cm; the biomass was 70.8 kg. The third and the fourth vertebrae showed Baastrup syndrome (compression of the vertebral spine). There were radiologic signs of deformity on the higher edge of the acetabula and results of frequent sprains of the ankles. 31A was a male individual, 47-54 years old. The height was 178.65 cm; the biomass was 81 kg. The vertebral index showed a heavy overloading in the thoracic lumbar region. There were bony formations under the periosteum on both on the higher and medium facets of the first metatarsus and on the higher and lateral facets of the fifth metatarsus on both sides. As the topography indicates, these small ossifications coincided with the contact points between the back of the foot and parts of the upper shoe. From the osseous remains, in particular from the teeth (central incisors), the DNA was extracted and typed to identify potential family ties among all the subjects. The extraction technique used came from the DNA Promega technique, partially modified by the authors. Stay times of the sample in the extraction buffer were increased and were increased the polymerase chain reaction (PCR) cycles.  相似文献

In recent years, development agencies (DAs) have focused their activities on consulting projects rather than on financing turnkey projects when assisting emerging markets. The main reason is that the implementation of consulting projects is likely to be connected with an intensive knowledge transfer from developed to emerging markets. Training of local employees and cooperation with local firms are necessary elements to make the transfer effective. The empirical statistics shows training and cooperation to be more frequent in consulting projects financed by DAs as compared to commercial projects. According to theory and experience, training should be included in projects in the least developed host countries, whereas local cooperation should be more frequent, the higher is the development level of the host country. However, DAs do not follow these rules of thumb in a convincing way. A policy implication of the paper is therefore that DAs should better organize and plan the contents of their consulting projects.

Several recent studies show European university scientists contributing far more frequently to company-owned patented inventions than they do to patents owned by universities or by the academic scientists themselves. Recognising the significance of this channel for direct commercialisation of European academic research makes it important to understand its response to current Bayh-Dole inspired reforms of university patenting rights. This paper studies the contribution from university scientists to inventions patented by dedicated biotech firms (DBFs) specialised in drug discovery in Denmark and Sweden, which in this respect share a number of structural and historic characteristics. It examines effects of the Danish Law on University Patenting (LUP) effective January 2000, which transferred to the employer university rights to patents on inventions made by Danish university scientists alone or as participants in collaborative research with industry. Sweden so far has left property rights with academic scientists, as they also were in Denmark prior to the reform. Consequently, comparison of Danish and Swedish research collaboration before and after LUP offers a quasi-controlled experiment, bringing out effects on joint research of university IPR reform. In original data on all 3,640 inventor contributions behind the 1,087 patents filed by Danish and Swedish DBFs 1990–2004, Difference-in-Difference regressions uncover notable LUP-induced effects in the form of significant reductions in contributions from Danish domestic academic inventors, combined with a simultaneous substitutive increase of non-Danish academic inventors. A moderate increase in academic inventions channelled into university owned-patents does appear after LUP. But the larger part of the inventive potential of academia, previously mobilised into company-owned patents, seems to have been rendered inactive as a result of the reform. As a likely explanation of these effects the paper suggests that exploratory research, the typical target of joint university-DBF projects in drug discovery, fits poorly into LUP’s requirement for ex ante allocation of IPR. The Pre-LUP convention of IPR allocated to the industrial partner in return for research funding and publication rights to the academic partner may have offered more effective contracting for this type of research. There are indications that LUP, outside the exploratory agenda of drug discovery, offers a more productive framework for inventions requiring less complicated and uncertain post-discovery R&D.
