Trifft den Verk?ufer nach der Vertragslage eine spezifische Pflicht, den Kaufgegenstand in eigener Verantwortung herzustellen bzw herstellen zu lassen (vgl § 1165 ABGB) und das Gesamtprojekt im zugesagten Sinn abzuwickeln und liegt dann eine (gravierende) Schlechterfüllung der vom Verk?ufer übernommenen Herstellungspflicht vor, dann hat er gem § 1298 ABGB zu behaupten (und zu beweisen), dass ihn an der vorgelegenen Verletzung seiner Leistungspflicht kein (eigenes) Verschulden (auch in seiner Funktion als Bauherr) trifft. Der Schaden der Erwerber aus der übertragung einer mit schweren Baum?ngeln behafteten Eigentumswohnung realisiert sich weder mit dem Anwartschaftsvertrag über eine noch gar nicht fertiggestellte Wohnung noch mit einer nachfolgenden provisorischen Nutzungsvereinbarung über die Wohnung, die lediglich ein Gebrauchsrecht vermittelt, sondern frühestens mit dem nachtr?glichen Abschluss des Kauf- und WE-Vertrags, weil erst dieser die Grundlage für den Eigentumserwerb am nicht vertragskonformen Leistungsgegenstand (wertgeminderte Eigentumswohnung) bildet. Keine Entscheidung der Frage, ob die lange 30-j?hrige Verj?hrungsfrist des § 1489 S 2 ABGB bereits mit der sch?digenden Handlung oder erst mit Schadenseintritt zu laufen beginnt.  相似文献

Attendance at trials of perpetrators could be retraumatizing for crime victims suffering from posttraumatic stress disorder. To investigate this hypothesis, two studies were conducted in which retraumatization was defined as a significant increase in posttraumatic stress reactions. A cross-sectional study of 137 victims of rape and nonsexual assault revealed that trial variables do virtually not predict posttraumatic stress reactionsat a time several years after trial. A longitudinal study of 31 victims of rape and nonsexual assault revealed intraindividual stability of posttraumatic stress reactions for the time interval from a few weeks before the trial to a few weeks after the trial; in addition, interindividual stability was high. The results of both studies do not support the retraumatization hypothesis, which should therefore be used with caution.  相似文献

The authors report on the estimation of the age of an unidentified deceased adolescent in connection with the body's identification. A physical examination by a forensic physician and an examination by a forensic dentist, including determination of the dental status and an X-ray of the teeth were used to estimate the age. In addition, an X-ray of the left hand as well as an X-ray and MRT scan of the clavicles were carried out by forensic radiologists. Combining the results of the individual examinations, the age of the deceased was estimated to range between 18 and 21 years. In the course of the police investigation it was found out that the deceased was 20 years and 7 months old. This has led to the conclusion that combined use of methods allows the age even of adolescents to be determined with relatively high accuracy and a minimum of time and effort.  相似文献

Pathology of peliosis   总被引:5,自引:0,他引:5  
Peliosis is a pathological entity characterized by the gross appearance of multiple cyst-like, blood-filled cavities within parenchymatous organs. Peliosis has been related to several underlying debilitating illnesses such as tuberculosis, hematological malignancies, the acquired immunodeficiency syndrome (AIDS), and post-transplant immunodeficiency, as well as intravenous drug abuse, chronic alcoholism, and in conjunction with the intake of oral contraceptives or steroids. The classical pathoanatomical concept is based upon the opinion that peliosis exclusively develops in organs belonging to the mononuclear phagocytic system (liver, spleen, bone marrow, and lymph nodes). However, a paucity of studies indicates that other organs such as lungs, parathyroid glands, and kidneys may be affected too. Concerning the underlying pathogenetic mechanisms of onset and maintenance of peliosis, the morphological data obtained by different investigators suggest that there is more than one path of formal pathogenesis (e.g., congenital malformation of vessels manifesting under altered local intravascular pressure conditions, acquired vascular disorder triggered by toxic noxae, active proliferation of vessels corresponding to the benign end on the spectrum of neoplastic vascular lesions). In the liver, at gross inspection, the peliotic lesions give the cut sections a "swiss cheese" appearance. Microscopically, two different types of peliosis can be distinguished in the liver: (1) "parenchymal peliosis" consisting of irregular cavities that are neither lined by sinusoidal cells nor by fibrous tissue, and (2) "phlebectatic peliosis" characterized by regular, spherical cavities lined by endothelium and/or fibrosis. One of the differential diagnoses that most closely resembles peliosis hepatis is secondary hepatic congestion due to veno-occlusive disease or the Budd-Chiari syndrome. In the spleen, the peliotic lesions may be arranged sporadically, disseminated, or in clusters in an uneven distribution pattern. Histologically, the cavities show frequently well-demarcated margins that may appear focally lined by sinusoidal endothelium, or totally lack a clear cell lining. Differential diagnoses are hemangiomas and involvement of the spleen in hairy-cell leukaemia. Since the disease may culminate in spontaneous rupture of the affected organ and thus may mimic a violent death at autopsy, peliosis is far more than just another morphological curiosity. Awareness of peliosis at autopsy as well as an appreciation for the histopathological changes in less characteristic or advanced cases may become an important issue for both the forensic and clinical pathologist.  相似文献

A 37-year-old Turkish woman was fatally injured by her 65-year-old Turkish husband with a stab to the cervical region. After her death he inflicted a deep cut to his own neck, which he survived thanks to immediate medical assistance. To the authors' knowledge this combination of a homicidal stab to the neck and a suicidal cut to the neck has not been described before. Kosher butchering, which is common in the couple's traditional cultural environment, is discussed as possible reason for the choice of the neck as site for applying sharp violence. It may have induced the perpetrator to choose this anatomical region.  相似文献

A collaborative study was carried out by the European DNA Profiling Group (EDNAP) in order to evaluate the performance of Y-chromosome binary polymorphism analysis in different European laboratories. Four blood samples were sent to the laboratories, to be analysed for 11 Y-chromosome single nucleotide polymorphisms (SNPs): SRY-1532, M40, M35, M213, M9, 92R7, M17, P25, M18, M153 and M167. All the labs were also asked to submit a population study including these markers. All participating laboratories reported the same results, indicating the reproducibility and robustness of Y-chromosome SNP typing. A total of 535 samples from six different European populations were also analysed. In Galicia (NW Spain) and Belgium, the most frequent haplogroup was R1b*(xR1b1,R1b3df). Haplogroup F*(xK) is one of the most frequent in Austria and Denmark, while the lowest frequency appear in Belgium. Haplogroup frequencies found in this collaborative study were compared with previously published European Y-chromosome haplogroup data.  相似文献

This article analyzes some factors underlying the spread ofinsurgent violence in Africa. It focuses on the impact externalfactors have on power struggles on the continent. The firstof these is the unsteady support for democracy from Westerndonors, which has impeded more far-reaching domestic changesin much of Africa. Second are wider changes in the internationalsetting that dramatically enhanced the international standingof armed movements in the post-1989 period. The article arguesthat the interplay of both factors has induced would-be leadersto conquer state power by violent rather than non-violent means.This becomes particularly evident in regard to Western effortsto solve violent conflict through power-sharing agreements.The hypothesis is put forward that the institutionalizationof this practice for the sake of ‘peace’, i.e. providingrebels with a share of state power, has important demonstrationeffects across the continent. It creates an incentive structurewould-be leaders can seize upon by embarking on the insurgentpath as well. As a result, and irrespective of their effectivenessin any given case, power-sharing agreements may contribute tothe reproduction of insurgent violence.  相似文献

In 1969 demands for greater rationality in education planninggave rise to new institutionalized forms of cooperation betweenthe federation and the Länder. Conflicts between the federaland Land governments, partisan conflicts, and financial conflictsoverlapped this cooperation. Despite the fact that the formalcapacity for dealing with conflicts had many shortcomings, ajoint general plan for education was issued in 1973 as a resultof favorable economic and political conditions. However, in1978 the federal government failed in its attempt to utilizethe dissatisfaction with the existing system of cooperationto extend its responsibilities for education. The deteriorationin economic and political conditions led to an end of effortsto formulate a general plan for education in 1982 and reducedthe scale of joint activities. Forms of educational cooperationbetween the federation and the Länder still exist, butthey no longer fulfill their original purpose. The centralizationof decisionmaking, which was originally expected, never cameinto being.  相似文献
