Postmortem redistribution (PMR) concerns blood drug concentration variations after death, depending on many factors such as sampling site and technique. In our study, we focused on sampling method. 30 cases were sampled, each at cardiac, subclavian, femoral, and popliteal sites. Targeted substances were diazepam, methadone, and morphine. Blind stick and dissection/clamping techniques were concomitantly performed at subclavian and femoral sites. Subclavian and femoral concentrations were compared according to technique used. To assess the influence of sampling technique on PMR, central/peripheral ratios were calculated depending on sampling method. Results show that drug concentrations tend to be lower when drawn from a clamped subclavian or femoral vein whereas ratios including subclavian and/or femoral blood concentration are influenced according to the technique used. In conclusion, clamping a subclavian or femoral vessel before sampling tends to result in lower drug concentrations and may influence ratios, suggesting the importance of isolating vessels from thoraco‐abdominal viscera.  相似文献

Der vorliegende Beitrag skizziert die besonderen Strukturen des deutschen F?deralismus, hebt seine Leistungen hervor, benennt seine Schw?chen, er?rtert seinen Reformbedarf und diskutiert die Chancen seiner Reform. Es wird gezeigt, dass eine Strukturreform des F?deralismus in Deutschland aufgrund von politisch-institutionellen Bedingungen besonders schwierig ist. Deshalb kann nur ein Teil des Reformbedarfs mit Aussicht auf Erfolg zum politischen Thema gemacht und in Reformvorhaben umgesetzt werden. Das bel?sst erhebliche Lücken zwischen Reformbedarf und Reformf?higkeit. Allerdings sind die Reformgrenzen mit den Leistungen des deutschen F?deralismus zu verrechnen. Diese Leistungen sind beachtlich, wie der internationale Vergleich und das Erreichen f?deralismusspezifischer Ziele, insbesondere Machtaufteilung und Integration, aber auch Einbindung der Opposition zeigen. überhaupt nicht gerüstet ist der F?deralismus (und mit ihm die Politik insgesamt) dafür, ein hochwahrscheinliches — aber derzeit kaum beachtetes — Folgeproblem des „sozialen Bundesstaates“ der Bundesrepublik zu bew?ltigen: Die Finanzierungslasten ihres leistungsstarken Sozialstaats erzeugen bedrohliche Engp?sse in der Finanzierung ?ffentlicher Ausgaben jenseits der Sozialpolitik.  相似文献

When addressing complex societal problems, public regulation is increasingly complemented by private regulation. Extant literature has provided valuable insights into the effectiveness of such complex governance structures, with most empirical studies focusing on how public regulation influences private regulation. Conversely, the impact of private on public regulation is less well studied. Here, we investigate this impact with a focus on technological change as possible mechanism. Based on a case study of energy efficiency in buildings in Switzerland, we find evidence of a symbiotic interaction between public and private regulation that leads to ratcheting-up of regulatory stringency. We identify technological change as the mechanism linking private and public regulation. We discuss the relevance of our findings for governance literature and regulators.  相似文献

Apart from typical suicides, there are sometimes unusual deaths from gunshots to the head. The presented case is a double death from the autopsy material of the Institute of Legal Medicine in Berlin. The report deals with a murder-suicide of a man, who killed himself and his 2-year-old daughter by a single gunshot. After having administered a tranquilizer to the child, he held her head to his own and fired a contact shot to his right temple so that the bullet passed through both heads.  相似文献

Despite strict assault weapons laws shooting deaths are not uncommon in the Federal Republic of Germany. Especially in multiple one-stage homicides shooting is a frequently established cause of death. The described double homicide from the autopsy material of the Berlin Institute of Legal Medicine shows the difficulties in the forensic assessment of gunshot wounds. It is noteworthy under criminalistic aspects how methodically the offender proceeded in the removal of the victims and how extensive the search for the bodies was, which were only found after calling in water search dogs.  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

Research on gender equality policy has generally focused on actors and institutions at the national and international levels. This article considers the role of local‐level actors and institutions in explaining different policy responses to violence against women and girls (VAWG). The literature on gender policy trajectories identifies the particular importance of executive actors in influencing “status policies” like VAWG. Quantitative data are analyzed to show how local Police and Crime Commissioners in England and Wales have responded to demands for policy action. The focus is on the interaction between the 41 elected commissioners and the new institutional arrangements for police governance introduced in 2012. The article shows that variation in policy outcomes is related (a) to the gender of executive actors and (b) to the way in which actors interpret elements of the institutional framework, regardless of their own gender.  相似文献

Im OECD‐Länder‐Vergleich erreicht die Schweiz bei zentralen Indikatoren des politischen Leistungsprofils Spitzenwerte, beispielsweise bei der Arbeitslosenquote, der Inflationsrate und dem Schuldendienst für die Staatsschulden. Wie diese Erfolgsgeschichte zu erklären ist, wird in diesem Essay anhand der Jahre von 1990 bis 2012 erörtert, und zwar unter Heranziehung von Hypothesen und Daten zu schweizspezifischen Erklärungen und von Erklärungsansätzen, die die Schweiz mit anderen wohlhabenden Demokratien vergleichen. Als Schlüsselgrößen erweisen sich – neben institutionellen, prozessualen und akteursbezogenen Eigenheiten der Schweiz – insbesondere die Variablen politikfeldspezifischer Erklärungen (wie Zentralbankautonomie, Verteilungskonflikt und fiskalpolitische Fragmentierung) sowie sozialpartnerschaftliche Arbeitsbeziehungen und Parteieneffekte.  相似文献

The term “post-black art” was invented in the late 1990's by Thelma Golden, curator and executive director of the Studio Museum in Harlem and Glenn Ligon, an African American artist. This paper examines the origins of the term, its definition and the extent to which the phrase challenges cultural practices that adversely impact artists of color and women. A discussion of the works of two African American artists who worked in the early part of the 20th century provides historical perspective on the origins of damaging cultural practices which prevailed for many decades. Though the civil rights movement instigated real change, the era unwittingly played a role in introducing cultural policies and practices that continued to limit the way in which the work of women and artists of color was presented and interpreted to the public. The paper concludes by observing the work of individual artists who circumvented those limiting cultural policies and practices and who in their imaginatively inventive ways of engaging the public were the precursors to the current "post-black" point of view.  相似文献
