This research note describes an integrated regional model of the interactions between water resources and society. It examines the relations between rural and urban sectors of society and the effect on resource use of changes in supply and demand due to climate change, population movements, and other natural and social processes. This modeling effort is part of a larger project conducted at the Potsdam Institute for Climate Impact Research to study the regional evolution of water resources in three different geographical areas. This larger project is in turn linked to the research focus on global water resources within the international Human Dimensions of Global Environmental Change Programme.  相似文献

Degradation of human DNA extracted from forensic stains is, in most cases, the result of a natural process due to the exposure of the stain samples to the environment. Experiences with degraded DNA from casework samples show that every sample may exhibit different properties in this respect, and that it is difficult to systematically assess the performance of routinely used typing systems for the analysis of degraded DNA samples. Using a batch of artificially degraded DNA with an average fragment size of approx. 200 bp a collaborative exercise was carried out among 38 forensic laboratories from 17 European countries. The results were assessed according to correct allele detection, peak height and balance as well as the occurrence of artefacts. A number of common problems were identified based on these results such as strong peak imbalance in heterozygous genotypes for the larger short tandem repeat (STR) fragments after increased PCR cycle numbers, artefact signals and allelic drop-out. Based on the observations, strategies are discussed to overcome these problems. The strategies include careful balancing of the amount of template DNA and the PCR cycle numbers, the reaction volume and the amount of Taq polymerase. Furthermore, a careful evaluation of the results of the fragment analysis and of automated allele calling is necessary to identify the correct alleles and avoid artefacts.  相似文献

A literature search was conducted to collect randomized controlled studies evaluating the outcome of psychological and psychosocial interventions after attempted suicide and deliberate self-harm. Twenty-five studies meeting the inclusion criteria were identified. The studies are grouped according to the psychological approach chosen for the intervention. They are discussed with regard to both the various therapeutic strategies and models used, and the repetition of self-harming behavior as the main outcome.  相似文献

A reliable determination of the post mortem interval (PMI) in human bones has neither been found by morphological nor by intensive analyses of other kinds. In most cases of legal medicine practice the question of PMI is restricted to a forensically relevant resting period. In a survey based upon literature, all osteological signs of decomposition, which have not been described for a soil embedded resting period of under 50 years, were collected. 21 research reports could be found, describing macroscopic findings on soil-embedded human bones with known PMI. All in all, 1295 individuals were examined in these investigations. A censorious review of the summarized results found in literature reveals that the following findings have never been seen in a PMI of 50 years or less. Outer appearance: macroscopically no adipocere, deep incisions of the outer compact layer, extensive defects of the bone surface, intense brownish-black lawn of microorganisms, fraying of the outer lamellar system, lifting of the cortical area, torsion of the tissue, attached brushit, bone manually breakable. On freshly sawn cross sections: lack of adipocere, brushit in the marrow area, reduced or lack of UV-fluorescence.  相似文献

Between 1880 and 1950, Swiss psychiatrists established themselves as experts in criminal courts. In this period, the judicial authorities required psychiatric testimonies in a rising number of cases. As a result, more offenders than ever before were declared mentally deficient and, eventually, sent to psychiatric asylums. Psychiatrists also enhanced their authority as experts at the political level. From the very beginning, they got involved in the preparatory works for a nationwide criminal code. In this article, I argue that these trends toward medicalization of crime were due to incremental processes, rather than spectacular institutional changes. In fact, Swiss psychiatrists gained recognition as experts due to their daily interactions with judges, public prosecutors, and legal counsels. At the same time, the spread of medical expertise had serious repercussions on psychiatric institutions. From 1942 onwards, asylums had to deal with a growing number of “criminal psychopaths,” which affected ward discipline and put psychiatry's therapeutic efficiency into question. The defensive way in which Swiss psychiatrists reacted to this predicament was crucial to the further development of forensic psychiatry. For the most part, it accounts for the subdiscipline's remarkable lack of specialization until the 1990s.  相似文献

Why does bureaucratic corruption occur in the EU system? Several examples suggest that bureaucratic corruption exists and that the Commission’s anti-fraud agency, OLAF, is not a fully independent authority. We thus develop a novel interpretation of the principal-supervisor-agent model to cope with non-independent anti-fraud units. This model shows that corruption is likely to occur when the expected value to the client from bribing the agent is larger than the expected value to the principal of truth-telling by the supervisor. Overall, this analysis points to the risks of flawed incentives and the lack of institutional independence among principal, agent, supervisor and client. Our main policy recommendations as a result of these findings are that OLAF should be placed outside the Commission, and that whistleblowers should receive adequate protection.  相似文献

This paper reassesses the claim that electronic voting systems help voters to avoid common mistakes that lead to their votes remaining uncounted. While prior studies have come to mixed conclusions, I provide new, more robust evidence based on a case study of extended Internet voting trials in Geneva canton, Switzerland. The trials almost exclusively involved referendum votes. For causal identification I exploit the unique circumstance that federal safety legislation created a near-natural experiment, with some of the canton’s municipalities participating in the trials and others not. Using difference-in-differences estimation, I find that the residual vote rate decreased by an average of 0.3 percentage points if municipalities offered the possibility to vote online in addition to (mostly optically scanned) paper ballots. For cantonal measures, which are located towards the bottom of ballot papers in Geneva, the reduction increases to 0.5 percentage points. These remain relatively modest effects, and I find no evidence for a knock-on effect on electoral outcomes. However, on average only around 20% of votes were cast online where the opportunity existed, and online voting was most popular among voters with high levels of education. Despite the small effect sizes, the results of this study therefore point to the potential of Internet and, more generally, electronic voting technology to reduce avoidable voter mistakes.
