Land engraved areas (LEAs) provide evidence to address the same source–different source problem in forensic firearms examination. Collecting 3D images of bullet LEAs requires capturing portions of the neighboring groove engraved areas (GEAs). Analyzing LEA and GEA data separately is imperative to accuracy in automated comparison methods such as the one developed by Hare et al. (Ann Appl Stat 2017;11, 2332). Existing standard statistical modeling techniques often fail to adequately separate LEA and GEA data due to the atypical structure of 3D bullet data. We developed a method for automated removal of GEA data based on robust locally weighted regression (LOESS). This automated method was tested on high-resolution 3D scans of LEAs from two bullet test sets with a total of 622 LEA scans. Our robust LOESS method outperforms a previously proposed “rollapply” method. We conclude that our method is a major improvement upon rollapply, but that further validation needs to be conducted before the method can be applied in a fully automated fashion. 相似文献

While some scholars call for mechanisms to give citizens a greater voice in politics, others critically question the demand for more citizen participation. Rather, they find that the people do not want to be involved in politics and prefer independent experts to make political decisions. This perspective is captured by Hibbing and Theiss-Morse in their concept of stealth democracy. They describe stealth democrats as people who think that political debates are unnecessary or who naturally avoid all sorts of conflict. Especially the latter argument points to a potential psychological underpinning of stealth attitudes, which forms the starting point of the investigation here. This article evaluates the personality of stealth democrats and makes use of a well-known concept to capture personality traits, the ‘Big Five’ model. Analysing unique survey data from Switzerland, the results reveal significant relationships between personality traits such as conscientiousness, agreeableness, and neuroticism and stealth attitudes. 相似文献

Skin lesions suspected to have been caused by a burning cigarette require thorough diagnostic evaluation as to the mode of infliction. Accidental cigarette burns must be differentiated from injuries due to self-infliction or maltreatment. The typical categories are presented on the basis of the literature and exemplary cases from the authors' own study material. An intentional infliction must be taken into consideration when a body region is involved which does not normally come into contact with a cigarette by chance. Full thickness burns from glowing cigarettes require an exposure time of more than 1s. One should also keep in mind the possibility of confusion with local skin infections or thermal effects by traditional medical practices (e.g. moxibustion). In unclear cases, repeated inspection of the lesion is recommended in order to facilitate its classification as to causation and age. The courses of healing in first- to third-degree cigarette burns are demonstrated by means of continuous photographic documentation. The discussion deals with different kinds of accidental and intentional cigarette burns, e.g. in drug addicts, psychiatric patients, victims of child abuse, maltreatment and torture, but also in persons feigning a criminal offence. 相似文献

Abstract A frequently cited recommendation of public service motivation (PSM) research is to use PSM in the context of HR marketing. However, empirical evidence demonstrating the usefulness of addressing PSM in the recruitment process is limited. Moreover, we know little about the relative importance of PSM for public employers’ attractiveness. We address this gap using an experimental research design to investigate whether public service motivated individuals differ from extrinsically motivated individuals in terms of their attraction to organizations that emphasize either “traditional” public or private values in their employer branding. Our findings indicate that public service motivated individuals are attracted neither to public nor to private values in employer branding. Furthermore, individuals with very high levels of extrinsic motivation are more attracted to private values employer branding than to public values employer branding and to the control group. 相似文献

In der Tradition von Alexis de Tocqueville wird zivilgesellschaftlichen Vereinigungen eine essentielle Bedeutung in der zwischenmenschlichen Vertrauensbildung zugeschrieben. Ziel des vorliegenden Beitrages ist es, den Zusammenhang zwischen Vereinsengagement und generalisiertem Vertrauen differenzierter zu betrachten und empirisch für die Schweiz zu untersuchen. Dabei werden sowohl das Engagement in verschiedenen Organisationstypen (brückenbildende vs. abgrenzende und isolierte vs. verbundene) als auch die vereinstypusunabhängige Integration miteinander verglichen. Empirische Analysen auf Basis aktueller Daten des Schweizer Freiwilligen‐Monitors 2007 kommen dabei zu dem Schluss, dass entgegen weitverbreiteter Meinung die Vertrauensentwicklung in der Schweiz weniger vom Engagement in spezifischen Vereinen abhängt, sondern vielmehr dem Ausmass der persönlichen Integrationsbereitschaft geschuldet ist. Von entscheidender Bedeutung für die Vertrauensentwicklung ist also nicht die Qualität der hier untersuchten einzelnen Vereinigungen, sondern die Quantität des persönlichen Engagements. 相似文献

Diese Arbeit präsentiert die erste vergleichend angelegte empirische Einschätzung zum Bestand des Sozialkapitals in der Schweiz. Hinsichtlich des zivilgesellschaftlichen Engagements in Vereinen und Freiwilligenorganisationen und gemessen am zwischenmenschlichen Vertrauen ist die Schweiz im internationalen Vergleich keinem Niedergang des sozialen Kapitals ausgesetzt, wie dies etwa für die Vereinigten Staaten konstatiert wird. Hingegen nimmt das Vertrauen in die politischen Institutionen und Akteure des Landes über die Zeit ab. Im internationalen Vergleich rangiert die Schweiz hinsichtlich ihres Bestandes an sozialem Kapital im oberen Mittelfeld. Weiter zeigen die Auswertungen, dass die deutschschweizer Sprachregion einen höheren Sozialkapitalbestand aufweist als die lateinischen Sprachregionen. Ein ressourcenreiches Profil begünstigt zudem den individuellen Erwerb von Sozialvermögen in Form von sozialem Vertrauen oder der Mitgliedschaft in Freiwilligenorganisationen. 相似文献

The authors report on a fatal pedestrian accident in which the victim lay on the street and got under a car being run over by one of the front wheels. Both the car driver and the killed pedestrian were strongly alcohol-intoxicated at the time of the accident (2.45 a.m.). After the car had come to a standstill, the pedestrian remained trapped under the car until she was rescued by the fire brigade. On the basis of the autopsy findings and the technical expert opinion it could be reconstructed that the pedestrian's death was not caused by the consequences of being run over by the car, but by the subsequent compression of her thorax in the final accident position. 相似文献
