In this series, the image quality and value of intraoperative 3D fluoroscopy with intravenous contrast agent for the evaluation of aneurysm occlusion and vessel patency after clip placement was assessed in patients who underwent surgery for intracranial aneurysms. Materials and methods Twelve patients were included in this retrospective analysis. Prior to surgery, a 360° rotational fluoroscopy scan was performed without contrast agent followed by another scan with 50 ml of intravenous iodine contrast agent. The image files of both scans were transferred to an Apple PowerMac® workstation, subtracted and reconstructed using OsiriX® free software. The procedure was repeated after clip placement. Both image sets were compared for assessment of aneurysm occlusion and vessel patency. Results Image acquisition and contrast administration caused no adverse effects. Image quality was sufficient to follow the patency of the vessels distal to the clip. Metal artifacts reduce the assessability of the immediate vicinity of the clip. Precise image subtraction and post-processing can reduce metal artifacts and make the clip-site assessable and depict larger neck-remnants. Conclusion This technique quickly supplies images at adequate quality to evaluate distal vessel patency after aneurysm clipping. Significant aneurysm remnants may be depicted as well. As it does not require visual control of all vessels that are supposed to be evaluated intraoperatively, this technique may be complementary to other intraoperative tools like indocyanine green videoangiography and micro-Doppler, especially for the assessment of larger aneurysms. At the momentary state of this technology, it cannot replace postoperative conventional angiography. However, 3D fluoroscopy and image post-processing are young technologies. Further technical developments are likely to result in improved image quality.}, language = {en} } @article{KestlerLuccaKrause2016, author = {Kestler, Thomas and Lucca, Juan Bautista and Krause, Silvana}, title = {'Break-In Parties' and Changing Patterns of Democracy in Latin America}, series = {Brazilian Political Science Review}, volume = {10}, journal = {Brazilian Political Science Review}, number = {1}, doi = {10.1590/1981-38212016000100004}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-171333}, pages = {e0004}, year = {2016}, abstract = {Although Lijphart's typology of consensus and majoritarian democracy can be regarded as the most widely used tool to classify democratic regimes, it has been rarely applied to Latin America so far. We try to fill this gap by adapting Lijphart's typological framework to the Latin American context in the following way. In contrast to previous studies, we treat the type of democracy as an independent variable and include informal factors such as clientelism or informal employment in our assessment of democratic patterns. On this basis, we aim to answer the following questions. First, how did the patterns of democracy evolve in Latin America over the two decades between 1990 and 2010 and what kind of differences can be observed in the region? Second, what are the institutional determinants of the observed changes? We focus on the emergence of new parties because of their strong impact on the first dimension of Lijphart's typology. From our observations we draw the following tentative conclusions: If strong new parties established themselves in the party system but failed to gain the presidency, they pushed the system towards consensualism. Conversely, new parties that gained the presidency produced more majoritarian traits.}, language = {en} } @incollection{Schmitz2016, author = {Schmitz, Barbara}, title = {"...using different names, as Zeus and Dis" (Arist 16).

Probably originating in the 2nd century BCE1, the book tells a legend of how the translation of the Torah into Greek came into being. This shows that translating a holy, canonical text or the first time needed explication. Notably, the translation of the godly nomos (Arist 3) comparatively takes up little space (Arist 301-307). And it has to be noted, that "God" is seldom a topic in the Book of Aristeas. The word (ὁ) θεός "God" is found in only three contexts: in the dialogue between king Ptolemaios and Aristeas (Arist 15-21), in the dialogue of the high priest Eleazar and Aristeas (Arist 121-171; above all 128; 130-141; 155-166; 168) and in the question-and-answer-speech during the symposium at the Ptolemaic royal court between the king and the Jewish scholars (Arist 184-294). In analysing the different statements regarding God, the frame of the narrative is of decisive importance: In the Book of Aristeas, "Aristeas" (Ἀριστέας), who writes in Greek, presents himself as the author, but he is also part of the story. Accordingly, Aristeas is the narrator, who tells the story from his own point of view, and at the same time, he is a character in the 'world' of the text. This Aristeas presents himself as a Greek and a Non-Jew (Arist 16; 121-171), who already wrote a book (Arist 6) and plans further publications (Arist 322). In the double-role as narrator of the text and protagonist in the text, Aristeas has to be differentiated from the (real) writer/author of the Book of Aristeas, who possibly was Jewish. That means that the (real, probably Jewish) author of the Book of Aristeas presents (or invents) "Aristeas" and gives him the role of the narrator of his text.3 The author portrays Aristeas as a Greek, non-Jewish character, who is a servant of the royal court. This differentiation between narrator and writer/author is of crucial importance for the question of the different conceptions of God in the Book of Aristeas.}, subject = {Gott}, language = {en} }
