A spatio-temporal visual analysis tool for historical dictionaries
[EN]The exploreAT! project aims to give insights into the richness of the German language in the Austrian area through a rich and unique collection of dialect words of the Bavarian dialects recorded during the former Austrian-Hungariann Monarchy period and beyond. Originally collected by means of questionnaires, words were noted in handwriting on individual paper slips, covering topics from nature and food to religious festivities, etc. Once digitized, the full database contains around 3.5 million single data entries with an estimated 200,000 headwords, which requires substantial effort if the analysts want to access specific information from the data set. It should also be noted that the data presents a high heterogeneity in terms of its nature and origin (from questionnaires, collectors, scientists, spoken language, hand written notes, etc.), which calls for the creation of a homogeneous database containing all of the available information.
In this paper we present a tool aimed to improve the comprehension of that massive amount of data through visualization means, thus trying to help in the reach of meaningful conclusions and the acquisition of valuable insights in easy and fast ways. With it, analysts can discover cultural issues and access them through means of language and visualization. This is possible thanks to a multidimensional approach to data analysis based on the use of maps, projections and other visualization artifacts. To reach our goal, a team of experts with different backgrounds worked together trying to close the gap between the Humanities and Computer Sciences fields through the creation of our prototype and its multiple iterations
Automated classification of static code analysis alerts: a case study
Due to copyright restrictions, the access to the full text of this article is only available via subscription.Static code analysis tools automatically generate alerts for potential software faults that can lead to failures. However, developers are usually exposed to a large number of alerts. Moreover, some of these alerts are subject to false positives and there is a lack of resources to inspect all the alerts manually. To address this problem, numerous approaches have been proposed for automatically ranking or classifying the alerts based on their likelihood of reporting a critical fault. One of the promising approaches is the application of machine learning techniques to classify alerts based on a set of artifact characteristics. In this work, we evaluate this approach in the context of an industrial case study to classify the alerts generated for a digital TV software. First, we created a benchmark based on this code base by manually analyzing thousands of alerts. Then, we evaluated 34 machine learning algorithms using 10 different artifact characteristics and identified characteristics that have a significant impact. We obtained promising results with respect to the precision of classification
Konfessionelle Konfliktlinien in der Eurokrise: Wie protestantische, orthodoxe und katholische Solidarität die Krise verschärfen
Die europäische Krise wurde bisher vor allem unter dem Stichwort “Spielarten des Kapitalismus“ in der Wissenschaft diskutiert. Das Erklärungspotenzial von unterschiedlichen Wirtschaftskulturen in Nord und Südeuropa wurde hingegen vernachlässigt. Dieser Beitrag untersucht die unterschiedlichen Solidaritätskonzepte die in Nord und Südeuropa vorherrschen, und zeigt wie sie aus den drei Hauptströmungen der europäischen Christenheit, Protestantismus, Katholizismus und Orthodoxie hervorgehen. Der Beitrag argumentiert, dass diese Unterschiede einen gemeinsamen, für alle Seiten akzeptierbaren Weg aus der Krise erschweren.
Religious Lines of Conflict in the European Crisis: How Solidarity of Protestantism, Orthodoxy and Catholicism Aggravate the Crisis
The European crisis has so far been primarily discussed through the conceptual lens of the Varieties of Capitalism approach. Different economic cultures that underpin the different economies on the European continent as a potential source of irritation during the crisis have been neglected. This contribution shows that the different solidarity concepts that prevail in Northern and Southern Europe can be linked back to divergences between the solidarity concepts of the three main strands of Christianity in Europe: Protestantism, Catholicism and Orthodoxy. These differences make a solution to the crisis that is equally acceptable to all difficult.

Cardioprotective effects of the Na(+)/H(+)-exchange inhibitor cariporide in infarct-induced heart failure
We investigated the effect of chronic treatment with the new Na(+)/H(+)-exchange inhibitor, cariporide, on cardiac function and remodelling 6 weeks after myocardial infarction (MI) in rats. Treatment with cariporide was commenced either 1 week pre or 30 min, 3 h, 24 h or 7 days after ligation of the left ventricular artery and was continued until haemodynamic parameters were obtained 6 weeks after MI in conscious rats. Compared to sham animals, untreated MI-controls developed pronounced heart failure after 6 weeks. Basal left ventricular end-diastolic pressure (in mmHg) was reduced in the groups in which cariporide was started 1 week pre (16.0+/-1.7) or 30 min (12.5+/-1.1), 3 h (11.8+/-1.0) and 24 h (13.0+/-2.5) after MI compared to untreated MI-controls (22. 4+/-1.5; P <0.01). Basal myocardial contractility (in 1000 mmHg/s) was only increased when treatment was initiated after 30 min (9. 0+/-0.7), 3 h (8.5+/-0.3) and 24 h (8.0+/-0.7) compared to untreated MI-controls (5.8+/-0.7; P <0.05-0.01). Infarct size (in % of left ventricular circumference) was 40.0+/-2.1 in MI-controls and was decreased when treatment was begun after 30 min (32.6+/-2.7) or 3 h (32.4+/-2.3) (P <0.05). In animals, in which cariporide was started 3 h after induction of MI, heart weight/body weight ratio was significantly decreased, indicating reduced cardiac hypertrophy. When treatment started 7 days after MI, cariporide did not exert any beneficial actions on structural and functional cardiac parameters. Our results show for the first time that chronic treatment with the Na(+)/H(+)-exchange inhibitor cariporide engendered marked cardioprotective effects when commenced before and up to 24 h after MI. The optimal time for the start of treatment was between 30 min and 3 h post M
