Application systems are often advertised with features, and features are used heavily for requirements man- agement. However, often software manufacturers only have incomplete information about the features of their software. The information is distributed over different sources, such as requirements documents, issue trackers, user manuals, and code. In this paper, we research the occurrence of feature information in open source software engineering data. We report on a case study with three open source systems. We analyze what information about features can be found in issue trackers and user documentation. Furthermore, we study the abstraction levels on which the features are described, how feature information is related, and we discuss the possibility to discover such information semi-automatically. To mirror the diversity of software development contexts, we choose open source systems, which are quite different, e.g., in the rigor of issue tracker usage. The results differ accordingly. One main result is that the user documentation did not provide more accurate information than the issue tracker compared to a provided feature list. The results also give hints on how the management of feature relevant information can be supported.
Ausgehend von den Anforderungen der EU-Rechtsprechung untersuchen die Autoren im Rahmen der vom Forschungsinstitut für Glücksspiel und Wetten (Hochschule Bonn-Rhein-Sieg, St. Augustin) erstellten Studie alternative Regulierungsmodelle für den Glücks- und Gewinnspielmarkt in Deutschland. Die gegenwärtige Regulierung ist nach ihrer Analyse nicht in der Lage, das dynamische Wachstum des nichtregulierten Glücks- und Gewinnspielmarktes zu begrenzen. Sie führt zur Migration von Spielern vor allem zugunsten der nichtregulierten Märkte, zu Sozialverlusten, da die Spieler auf den nichtregulierten Glücks- und Gewinnspielmärkten nicht wirksam in Konzepte des Spieler- und Jugendschutzes einbezogen werden können, sowie zu Wettbewerbsverzerrungen zwischen verschiedenen Glücks- und Gewinnspielformen. Die Einbeziehung des derzeitigen Graumarktes in die Regulierung sei dringend erforderlich. Dies würde zu einer ökonomisch gebotenen Planungssicherheit führen, fiskalische Mehreinnahmen generieren und einen deutlich effizienteren Spieler- und Konsumentenschutz ermöglichen.

Über die Saison verteilt möchten wir so verstärkt über die Events und unsere Zusammenarbeit mit unseren Sponsoren berichten und unseren Mitgliedern die Chance geben, Ihre Arbeit im Team vorzustellen.
Trotz einer sauber aufgesetzten Projektplanung und der konsequenten Einhaltung der vorgeschriebenen PM-Methodik verfehlen Projekte oft ihre Zielvorgaben. Einer der wichtigsten Gründe hierfür ist die stark gestiegene Komplexität. Diese erfordert eine neue Sichtweise auf das Projektmanagement, wie Olaf Ihlow in seinem Trend-Beitrag meint.

Verantwortliches Wirtschaften beschreibt die Betrachtung ökonomischer, ökologischer und sozialer Aspekte als ganzheitliches Konzept sowie deren Integration in die betriebswirtschaftliche Praxis mit dem Ziel, Wettbewerbsfähigkeit zu erhalten und Unternehmensrisiken zu minimieren. Verantwortliches Wirtschaften steht zudem für die Verpflichtung eines Unternehmens gegenüber seinen Stakeholdern sowie seiner Verantwortung gegenüber der Gesellschaft.
Improving the study entry supports students in a decisive phase of their university education. Implementing improvements is a change process and can only be successful if the relevant stakeholders are addressed and convinced. In the described Teaching Quality Pact project evaluation data is used as a mean to discuss in the university the situation of the study programs. As these discussions were based on empirical data rather than on opinion, it was possible to achieve an open discussion about measures that are implemented. The open discussion is maintained during the project when results of the measures taken are analyzed.
Unexpected Situations in Service Robot Environment: Classification and Reasoning Using Naive Physics

In the field of domestic service robots, recovery from faults is crucial to promote user acceptance. In this context we focus in particular on some specific faults, which arise from the interaction of a robot with its real world environment. Even a well-modelled robot may fail to perform its tasks successfully due to unexpected situations, which occur while interacting. These situations occur as deviations of properties of the objects (manipulated by the robot) from their expected values. Hence, they are experienced by the robot as external faults.
As soon as data is noisy, knowledge as it is represented in an information system becomes unreliable. Features in databases induce equivalence relations—but knowledge discovery takes the other way round: given a relation, what could be a suitable functional description? But the relations we work on are noisy again. If we expect to record data for learning a classification of objects then it can well be the real data does not create a reflexive, symmetric and transitive relation although we know it should be. The usual approach taken here is to build the closure in order to ensure desired properties. This, however, leads to overgeneralisation rather quickly.

Exposure to microgravity conditions causes cardiovascular deconditioning in astronauts during spaceflight. Until now, no specific drugs are available for countermeasure, since the underlying mechanism is largely unknown. Endothelial cells (ECs) and smooth muscle cells (SMCs) play key roles in various vascular functions, many of which are regulated by purinergic 2 (P2) receptors. However, their function in ECs and SMCs under microgravity conditions is still unclear. In this study, primary ECs and SMCs were isolated from bovine aorta and verified with specific markers. We show for the first time that the P2 receptor expression pattern is altered in ECs and SMCs after 24 h exposure to simulated microgravity using a clinostat. However, conditioned medium compensates this change in specific P2 receptors, for example, P2X7. Notably, P2 receptors such as P2X7 might be the important players during the paracrine interaction. Additionally, ECs and SMCs secreted different cytokines under simulated microgravity, leading into a pathogenic proliferation and migration. In conclusion, our data indicate P2 receptors might be important players responding to gravity changes in ECs and SMCs. Since some artificial P2 receptor ligands are applied as drugs, it is reasonable to assume that they might be promising candidates against cardiovascular deconditioning in the future.
It is a euphemism to say that humans use tools. Humans possess a vast repertoire of tools they use every day. In fact, as language or bipedal locomotion, tool use is a hallmark of humans. Tool use has also been often viewed as an important step during evolution (van Schaik et al., 1999) or even as a marker of the evolution of human intelligence (Wynn, 1985). So a fundamental issue is, what are the cognitive and neural bases of human tool use? The present series of papers in this special topic represents the newest additions to that research topic.
The case for basic human needs in coaching: A neuroscientific perspective - The SCOAP Coach Theory
(2014)
Perception is one of the most important cognitive capabilities of an entity since it determines how an entity perceives its environment. The presented work focuses on providing cost efficient but realistic perceptual processes for intelligent virtual agents (IVAs) or NPCs with the goal of providing a sound information basis for the entities' decision making processes. In addition, an agent-central perception process should rovide a common interface for developers to retrieve data from the IVAs' environment. The overall process is evaluated by applying it to a scenario demonstrating its benefits. The evaluation indicates, that such a realistically simulated perception process provides a powerful instrument to enhance the (perceived) realism of an IVA's simulated behavior.
Residential and commercial buildings are responsible for about 40% of the EU’s total energy consumption. However, conscious, sustainable use of this limited resource is hampered by a lack of visibility and materiality of consumption. One of the major challenges is enabling consumers to make informed decisions about energy consumption, thereby supporting the shift to sustainable actions. With the use of Energy-Management-Systems it is possible to save up to 15%. In recent years, design approaches have greatly diversified, but with the emergence of ubiquitous- and context-aware computing, energy feedback solutions can be enriched with additional context information. In this study, we present the concept “room as a context” for eco-feedback systems. We investigate opportunities of making current state-of-the-art energy visualizations more meaningful and demonstrate which new forms of visualizations can be created with this additional information. Furthermore, we developed a prototype for android-based tablets, which includes some of the presented features to study our design concepts in the wild.
