§ 25c KSchG legt in Satz 1 eine Informationsobliegenheit des Unternehmers gegenüber dem Verbraucher im Fall einer Interzession fest. Danach hat der Unternehmer den interzedierenden Verbraucher auf die wirtschaftliche Lage des Schuldners hinzuweisen, wenn er erkennt oder erkennen muss, dass der Schuldner seine Verbindlichkeit voraussichtlich nicht oder nicht vollst?ndig erfüllen wird. Unterl?sst der Unternehmer diese Information, haftet der Interzedent nur, wenn er seine Verpflichtung trotz einer solchen Information übernommen h?tte (§ 25c S 2 KSchG). Der folgende Beitrag besch?ftigt sich unter intensiver Berücksichtigung der jüngeren Judikatur mit den vielf?ltigen Aspekten der Interzedentenschutzvorschrift des § 25c KSchG, nicht zuletzt auch mit dem Mysterium der "echten Mitschuld".  相似文献

Eine jüngst ergangene Entscheidung des OGH (6 Ob 204/11k wbl 2012, 291) bietet Anlass, über das Verh?ltnis der Ausfallshaftung (§ 70 GmbHG) zum Kaduzierungsverfahren (§ 66 GmbHG) nachzudenken. Die Rechtsfrage lautet: Bedarf die Geltendmachung der Ausfallshaftung der vorherigen Durchführung eines Kaduzierungsverfahrens?  相似文献

Little research has investigated the prevalence of mood disturbance among sex offenders despite the fact that psychological distress may bear some relationship to community reintegration, and ultimately, recidivism. All offenders on New Jersey’s sex offender Internet registry were mailed surveys about their experiences with, and perceptions of, notification and residence restriction statutes, the Beck Depression Inventory-II (BDI-II), and the Beck Hopelessness Scale (BHS). On average, respondents (N = 104) reported mild to moderate levels of depressive symptoms (M BDI = 17.1) and hopelessness (M BHS = 6.9). Additionally, offenders who reported being negatively affected by residence restrictions and notification statutes reported higher levels of both depression and hopelessness. Given evidence that sex offender specific legislation may de-stabilize offenders, this research highlights the importance of managing affective states in this population.  相似文献

Presidential candidates regularly use crime issues to help win electoral support. Contrary to conventional wisdom, crime control became an issue in the 2008 presidential campaign. Despite decreasing crime rates and public opinion focused only temporarily on illegal immigration, the three major presidential candidates (Obama, Clinton, & McCain) discussed many anticrime initiatives during the campaign. Unlike past research which has found presidential candidates use primarily symbolic rhetoric in their anticrime rhetoric, all three presidential candidates in the 2008 presidential election were found to have employed tangible statements. The article discusses the different findings, making recommendations for future research.  相似文献

The publication deals with topics concerning the interpretation of the Vigrahavyāvartanī in as much as they are relevant for the understanding of (early) Madhyamaka-philosophy in general. A major part of the article is dedicated to a critical assessment of a number of views which have been propagated recently in a paper by Sharma (In: Nagoya studies in Indian culture and Buddhism, Saṃbhāṣā, 2011). A primary goal of the present investigation consists in substantiating the claim that early Madhyamaka represents a metaphysical teaching which stands in sharp contrast not only to stances of common sense but also to tenets propagated in Buddhist dogmatics.  相似文献

The in vitro production of GHB was observed in freshly collected, untreated whole blood samples using glass BD-Vacutainers and polypropylene S-monovettes. GHB concentrations were determined daily over a period of one week and after 3, 6 and 9 weeks again. Furthermore, the GHB concentration in 40 untreated random whole blood samples stored at 4°C for a longer period of time (10 samples 12 month, 10 samples 24 month and 20 samples 36 month) was also determined. For comparison, the in vitro production of GHB in freshly collected and prepared serum samples was observed. GHB serum concentrations were determined three times over a period of one week and once again after six weeks. Sample preparation was performed by means of methanolic extraction following the precipitation of whole blood and serum samples. A methanolic standard calibration was done in a low range of 0.005-0.1 μg/mL (LOD: 0.004, LLOQ: 0.013). For quantification a spiked blood bank serum with a determined GHB concentration of 0.09 μg/mL was used. Corrected calibrations in the range of 0.09-5.09 μg/mL were used (LOD: 0.08 μg/mL, LLOQ: 0.30 μg/mL), recovery: 91.3% (high level: 4.09 μg/mL) 50.5% (low level: 0.19 μg/mL). RESULTS: Relevant elevation of GHB was observed in all whole blood samples stored in liquid form (4°C or room temperature). In two of the 40 whole blood samples stored over a longer period of time at 4°C, GHB concentrations in the range of 13 μg/mL were even determined. These findings constitute grounds for caution. Even a GHB cut-off level of 5 μg/mL cannot be considered as "absolutely positive" proof of a case of exogenous administration, at least in untreated liquid blood samples in long time storage. However, no significant elevations of GHB were otherwise observed in any of the serum samples independently of storage temperature nor in the whole blood samples that were frozen for storage. CONCLUSIONS: The results suggest that the cut-off for exogenous GHB of 5 μg/mL could be lowered significantly, with the consequence of winning valuable time for the potential victim, but only if serum is collected for GHB determination or if the whole blood sample is frozen immediately after collection and the procedure well documented.  相似文献
