The concepts of "density" and "urban morphology" are today at the centre of debates on architecture and urban planning. The concept of"density" provides a solution to the issue of urban sprawl and, consequently, offers a way of rethinking sustainable urban and rural development. The densification of urban centres makes it possible to reduce a vulnerability related to the excessive use of suburban areas. However, densification is not a "turnkey" solution. Numerous criteria relating to its use are poorly understood. As numerous contemporary experiences have demonstrated, urban densification exposes space systems to new, unknown forms of vulnerability. First, the concept of "vulnerability" will be defined, specifically that of urban vulnerability, as well as related concepts, such as those of risk, hazard, and challenges. Secondly, forms of vulnerability inherent in the over-densification paradigm are pinpointed: This will involve determining the specific hazards, challenges, and risks of this space system. Thirdly, the authors will demonstrate how the concept of "compactness" makes it possible to review at the different urban levels the densification processes of territories and urban areas. Finally, a tool for the optimisation of compact urban morphologies for use in countering the related hazards and risks will be proposed. 相似文献

The regulation of intellectual property rights takes place in a range of international venues. This proliferation of international venues greatly enhances the potential for venue shopping. We argue that different levels of domestic regulation and differing degrees of judicialization account for actors' preferences over institutional venues. We take into consideration two scenarios. Conceiving of judicialization as the delegation of adjudication to an independent third party and the enforcement through multilaterally authorized sanctions, we show that: (i) upward regulatory harmonization leads actors preferring weak regulatory intellectual property rights standards to strive for venues with low degrees of judicialization, whereas those favoring stringent intellectual property rights protection prefer highly judicialized venues; and (ii) downward harmonization leads to the opposite constellation of institutional preferences. We show how these expectations hold by way of in‐depth case studies of two instances of global intellectual property rights regulation: the regulation of plant genetic resources and intellectual property rights for medicines. 相似文献

In most Western European countries, including Belgium, judicial alternative sanctions are increasingly being used for drug users. Because no study into the effectiveness of Belgian judicial alternatives for drug users has yet been carried out, this became the objective of the current research. The design of this study comprises a pre and post measurement of the criminal activity, drug use and situation in different spheres of life of 565 drug-dependent offenders. Two conclusions can be drawn. First, after an alternative sanction or measure is imposed, there is a reduction in the criminal activity of the offender. Second, this crime reduction goes hand in hand with a progress in several relevant life spheres. 相似文献

We report three cases of tri-allelic patterns observed during routine forensic casework on 5964 Belgian residents. These individuals had been typed for the following 15 autosomal STRs: CSF1PO, D3S1358, D5S818, D7S820, D8S1179, D13S317, D16S539, D18S51, D21S11, vWA, FGA, TH01, TPOX, D2S1338 and D19S433.The first example of a tri-allelic pattern had the genotype 13;15;16 for the D8S1179 locus. In the second observation there was 16;21;22 pattern for the D18S51 locus. The third case had the alleles 10;11;13 also for D18S51.All cases belonged to the Type I tri-allelic pattern, with three uneven peaks, the sum of the heights of both smaller peaks equalling the height of the tallest peak.Three cases in 5964 typed individuals is a frequency for tri-allelic patterns in autosomal STRs of 0.05%. 相似文献

Described here is a case of suicide with the use of a chainsaw. A female suffering from schizophrenia committed suicide by an ingenious use of a chainsaw that resulted in the transection of her cervical spine and spinal cord. The findings of the resulting investigation are described and the mechanism of suicides with the use of a chainsaw is reviewed. A dry bone study was realized to determine the bone sections, the correlation between anatomic lesions and characteristics of chainsaw. The damage of organs and soft tissues is compared according to the kinds of chainsaw used. 相似文献

Poisoning may also lead to both coma and multiple organ failure, also in youngsters without a known major medical history. As not all toxic agents are routinely screened when a poisoning is suspected, it is useful to consider less frequently encountered poisons in certain cases. We describe the occurrence of asystole and multiple organ failure which occurred in a young man after a suspected tramadol overdose. The tramadol concentration on admission in the ICU was indeed 8 microg/ml (mg/l), far above the therapeutic range. Subsequently, the patient developed severe acute liver failure, finally leading to death. Post-mortem toxicology did not reveal any other poison responsible for this unfavourable course as only very high serum and tissue tramadol and desmethyltramadol concentrations were found. Only a few fatal poisonings attributable to tramadol alone, as observed in our case, have been reported. An overview of these cases is presented. 相似文献

Psychological pain has been reported to be major contributing factor for completed suicide, and classical suicidology based its wisdom on this construct. In this paper we report the case of a patient whose family experienced a high number of suicides apparently due to an escalation of psychological pain in the family members after the successive suicides. We also briefly discuss the problem of helping survivors after the suicide of loved one. 相似文献

神话话语的神话性,典型地反映了与经验思维完全不同的神话思维模式.对神话话语的传播过程的探讨,是研究人类文明传承机制的重要一环.神话话语的交流或传播,只有放在人类一般交流方式的总体框架内加以考察,才有可能揭示其中的本质规律. 相似文献
