Empirical evidence suggests that the propensity to cooperate in common pool resource dilemmas is higher for small, homogeneous groups with efficacious monitoring and sanctioning mechanisms. Given that transition from socialist to market economies is associated with larger, more heterogeneous groups with diluted opportunities for monitoring and sanctioning, individuals in later-stage transition economies may be expected to be less cooperative than their early-stage counterparts. However, evidence from experiments conducted with subjects in two economies at different stages of transition suggests that this may not be the case. These findings have implications for both theorists and practitioners alike. 相似文献

Estimating the Skull‐to‐Camera Distance from Facial Photographs for Craniofacial Superimposition 下载免费PDF全文
Carl N. Stephan Ph.D. 《Journal of forensic sciences》2017,62(4):850-860
The overlay of a skull and a face image for identification purposes requires similar subject‐to‐camera distances (SCD) to be used at both photographic sessions so that differences in perspective do not compromise the anatomical comparisons. As the facial photograph is the reference standard, it is crucial to determine its SCD first and apply this value to photography of the skull. So far, such a method for estimating the SCD has been elusive (some say impossible), compromising the technical validity of the superimposition procedure. This paper tests the feasibility of using the palpebral fissure length and a well‐established photographic algorithm to accurately estimate the SCD from the facial photograph. Recordings at known SCD across a 1–10 m range (repeated under two test conditions) demonstrate that the newly formulated method works: a mean SCD estimation error of 7% that translates into <1% perspective distortion error between estimated and actual conditions. 相似文献

The combination of leniency programmes, high sanctions, complaints from customers and private actions for damages, has proven very successful at uncovering and punishing cartel agreements in United States Antitrust Law. Countless jurisdictions are being encouraged to adopt these ‘conventional’ enforcement tools, in the absence of an international competition authority. This paper identifies three issues which may undermine the universal efficacy of these cartel laws: (i) corruption and organized crime; (ii) social norms that are sympathetic to collusive practices; (iii) collectivist business cultures built on personal relationships. 相似文献

Abstract: Authentic black-powder muzzle-loader weapons or replicas are used today primarily for re-enactments of historic battles. A lay actor playing the role of a Prussian infantryman sustained life-threatening gunshot injuries during a recent re-enactment of a historic battle of the Sixth Coalition. As only blank historic muzzle-loading weaponry was used, the origin of the missile causing the wounding was initially unclear. Further investigation revealed a ramrod that had been propelled out of the barrel of another gunner's smooth-bore gun as cause of injury. The ramrod was hurled on a trajectory of more than 20 m, breaking the victim's shouldered barrel and hitting the victim resulting in severe abdominal, thoracic, and upper limb injuries. The critical incidents while handling muzzle-loading weaponry leading to premature discharge are elucidated. Furthermore, this report demonstrates how actual diagnostics and subsequent surgical treatment enabled this infantryman to survive an injury to which his comrades-in-arms would have succumbed 200 years ago. 相似文献

Nanoscience and nanotechnology are science fields which are growing extremely dynamically. Germany occupies the top position
in Europe and is only second to the US worldwide, which can be attributed to growing research promotion by the state. Based
on a general conceptual framework on the role of different types of standards in the research process and technology life
cycle, we argue that the market success of nanotechnology applications depends very much on the development of corresponding
standards, which clarify not only terminology, measurement and testing methods, but also regulate safety and health aspects
and specify interfaces. Other countries, European and international standardisation organisations have launched first initiatives
rather early. However, Germany was not able to translate its excellent starting position in nanotechnology research into a
leading position in standardisation initiatives, which pave the way for future commercialisation of nanotechnology and also
the basis for the next generation of research activities. Based on a survey among stakeholders of German nanotechnology research,
we are able not only to provide a first empirical validation of our conceptual model on the role of standards in the research
process, but also to define the major problems at the interface between research and standardisation, and finally, to recommend
possible options for their solution.

Blood aspiration is a significant forensic finding. In this study, we examined the value of postmortem computed tomography (CT) imaging in evaluating findings of blood aspiration. We selected 37 cases with autopsy evidence of blood in the lungs and/or in the airways previously submitted to total-body CT scanning. The CT-images were retrospectively analyzed. In one case with pulmonary blood aspiration, biopsy specimens were obtained under CT guide for histological examination. In six cases, CT detected pulmonary abnormalities suggestive of blood aspiration, not mentioned in the autopsy reports. CT reconstructions provided additional data about the distribution and extent of aspiration. In one needle-biopsied case, the pulmonary specimens showed blood in the alveoli. We suggest the use of CT imaging as a tool complementary to traditional techniques in cases of blood aspiration to avoid misdiagnosis, to guide the investigation of lung tissue, and to allow for more evidence-based inferences on the cause of death. 相似文献

Anthropometric, mortality, and population data presented by Svedberg [1990] in this journal suggested a slight anti‐male bias in undernutrition in sub‐Saharan Africa. This article re‐analyses some of the same anthropometric, mortality, and population data and supplements them with more recent findings. In contrast to Svedberg's results, it finds evidence of a slight and rising anti‐female bias in sub‐Saharan Africa, which is particularly apparent in mortality and population indicators. 相似文献
