Kein Provisionsanspruch bei einem vom Makler veranlassten Irrtum über den Wert der Liegenschaft

Ist der Grund für die Nichtausführung des vom Makler vermittelten Kaufvertrags dessen unrichtige Information über den Wert der Liegenschaft, liegt ein wichtiger Grund iSd § 7 Abs 2 MaklerG vor, weil die Nichtausführung des Gesch?fts gerade auf ein Verhalten des Vermittlers zurückzuführen ist.     

Comparative dental radiographic identification using flat panel CT

A skull without lower jaw was found and brought in for identification. It was suspected to be that of a man reported missing five years ago. An undated antemortal dental chart and two dental films of the 1st and 2nd dental quadrants, both taken about 4 years before the man went missing, were available for comparison. The method of choice in solving the identity question was comparative dental radiography. Despite numerous attempts, it was not possible to obtain radiographs of the upper jaw that duplicated the X-ray beam angulation of the antemortem dental films. The skull was thus scanned with a multislice computed tomography (MSCT) scanner, and virtual radiographs with the desired angulation were generated from the data with the maximum intensity projection (MIP) technique. The resulting virtual radiographs could, however, not be used for superimposition with the antemortem radiographs because of their poor resolution and the occurrence of artifacts caused by metallic dental fillings. The upper jaw was therefore scanned again, this time with a high resolution eLU-CT (eXplore Locus Ultra flat panel CT). The resulting eLU-CT datasets were visualized with the MIP technique and yielded virtual radiographs that could be compared with the antemortem radiographs. Positive identification could be assumed with near certainty after dental features could be matched in the superimposition of antemortem and postmortem radiographs. In the presented case, eLU-CT was used for the first time for a comparative dental radiographic identification.     

Informal university technology transfer: a comparison between the United States and Germany

Existing literature has confined university technology transfer almost exclusively to formal mechanisms, like patents, licenses or royalty agreements. Relatively little is known about informal technology transfer that is based upon interactions between university scientists and industry personnel. Moreover, most studies are limited to the United States, where the Bayh-Dole Act has shaped the institutional environment since 1980. In this paper, we provide a comparative study between the United States and Germany where the equivalent of the Bayh-Dole Act has come into force only in 2002. Based on a sample of more than 800 university scientists, our results show similar relationships for the United States and Germany. Faculty quality which is however based on patent applications rather than publications serves as a major predictor for informal technology transfer activities. Hence, unless universities change their incentives (e.g., patenting as one criterion for promotion and tenure) knowledge will continue to flow out the backdoor.     

Image-guided virtual autopsy findings of gunshot victims performed with multi-slice computed tomography and magnetic resonance imaging and subsequent correlation between radiology and autopsy findings

Because the use of radiology in modern forensic medicine has been, until today, mostly restricted to conventional X-rays, which reduces a 3D body to a 2D projection, a detailed 3D documentation of a gunshot's wound ballistic effects was not possible. The aim of our study was to evaluate whether the progress in imaging techniques over the last years has made it possible to establish an observer-independent and reproducible forensic assessment using multi-slice computed tomography (MSCT) and magnetic resonance imaging (MRI) technologies for the documentation and analysis of gunshot wounds. The bodies of eight gunshot victims were scanned by MSCT and by MRI; the data of these imaging techniques were post-processed on a workstation, interpreted and subsequently correlated with the findings of classical autopsy. With the spiral CT and MRI examinations and the subsequent 2D multi-planar reformation (MPR) and 3D shaded surface display (SSD) reconstruction, the entire gunshot-created complex skull fractures and brain injuries (such as wound channels and deeply-driven bone splinters) could be documented in complete and graphic detail. CT and MRI also documented vital reaction to the gunshot by demonstrating air emboli in the heart and blood vessels and the classic pattern of blood aspiration to the lung. Gunshot residues deposited within and under the skin were visible. In conclusion, we think that the radiological methods of MSCT and MRI have the potential to become a routine "virtual autopsy" tool in the future. Bullets and relevant histological samples from specific sites then might be won in image-guided minimally invasive fashion via percutaneous biopsy. The rapid application of developing radiological methods may lead to new horizons in forensic documentation and intravital as well as postmortem examination.     

Generalisierung von Beschäftigungsrisiken oder anhaltende Arbeitsmarktsegmentation?

The article inquires whether segmentation concepts might shed a new light on the debates about the generalization of employment risks in Germany and develops the concept of firm employment sub-systems. The result of our empirical analyses is that the German labour market structure is shifting from a hegemony of Internal Labour Markets to a tense and instable co-existence of Internal and External markets, with East Germany having taken the lead. There is neither a generalisation of risks nor a stable division of employment. We rather observe dynamic segmentation with shifts between Internal and External Markets and endogenous transformations within segments.     

Voters AS A Hard Budget Constraint: On the Determination of Intergovernmental Grants

Recent empirical literature has shown that the determination of intergovernmental grants is highly influenced by the political bargaining power of the recipient states. In these models federal politicians are assumed to buy the support of state voters, state politicians and state interest groups by providing grants. In this paper we provide evidence that the fiscal referendum reduces the reliance of states on matching grants received from the central government and thus the possibility of interest groups and state bureaucrats to obtain more grants. If referendums are available, voters serve as a hard budget constraint.
