Gender-specific differences in the frequency of depression to the disadvantage of women have been known for decades. In Germany, there is evidence that the prevalence of mental disorders also differs by occupation. The present study investigates whether for women working in male-dominated occupations and for men working in female-dominated occupations is related to depressive symptoms independently from other factors like work stress and work-family conflict. Special attention is paid to gender differences. Moreover, women are distinguished according to their working time (full-time or not). We use data from the first wave of the lidAstudy for our analyses. We make use of the applied Beck Depression Inventory, the effort-reward imbalance scales as well as the work-family conflict scale. Occupational gender segregation is defined as a share of 80 % of men and women per occupation, respectively. For women, the results of the multivariate analyses show an independent relationship between depressive symptoms and working in male-dominated occupations. Furthermore, significant interactions between occupational gender segregation and work stress are observed in both men and women regarding depressive symptoms.
The definition of individual creativity is based on a tension between novelty on the one side and usefulness respectively appropriateness on the other side. The paper explores how this tension pervades the stage and componential theories of creativity. To achieve this, the so called value square (“Wertequadrat”) developed by Helwig (1967) and Schulz von Thun (1998)is used which balances a value with its countervalue to analyze creativity. The author identifies tensions of action and inaction, expertise and mindfulness, precision and ambiguity as well as immersion and detachment permeating the creative process and the components of creativity. As a conclusion a morphological box for creativity is presented which allows one to show which combination of characteristics of the tensions support different stages of creativity. Furthermore implications for development and time management are discussed.
»Community Music in Theorie & Praxis« hieß die internationale Tagung, die kürzlich in München stattfand. »Community Music ist ein international gebräuchlicher Sammelbegriff für musikalische Aktivitäten«, heißt es im Konferenz-Flyer, »die in das soziale und räumliche Umfeld der Teilnehmenden eingebunden sind.« Community Music? Nie gehört? Wir sprachen mit Alicia de Banffy-Hall.
Psychosoziale Arbeitsbelastungen sind ein Risikofaktor für die Gesundheit Erwerbstätiger. Da die Erwerbsbevölkerung immer älter wird, stellen sich in diesem Kontext neue Fragen: In welchem Maße fühlen sich älterwerdende Beschäftigte durch Arbeitsanforderungen und ausbleibende Anerkennung belastet? Wie hängen solche Aspekte psychosozialer Arbeitsbelastungen mit der Gesundheit zusammen? Auf Basis einer aktuellen Befragung von älteren Erwerbstätigen werden diese Zusammenhänge hier näher untersucht.
We derive a nonlinear model of the steam cycle of a solar power plant, estimate its unknown parameters with measured data, and design a linear model predictive controller based on the resulting model. Simulations show that the linear model predictive controller is able to regulate the electrical power of the nonlinear steam process of the plant to a given reference trajectory very well. Moreover, it results in very good disturbance rejection.
Im Rahmen dieser Bachelorthesis sollen die Möglichkeiten für eine Migration des Nutzerwelten Programmcodes in die neuen Eclipse 4 Versionen ermittelt und anhand von Beispielen schrittweise erklärt werden. Hierbei werden zunächst die neuen Möglichkeiten erläutert die eine Eclipse 4 Entwicklung bietet und welche Vorteile durch die Einführung von Dependency Injections und dem Application Model entstanden sind. Anschließend werden die möglichen Wege zur Durchführung einer Migration aufgezeigt und auf ihre Vorteile und Nachteile überprüft. Im letzten Abschnitt werden schließlich die Migrationswege anhand von Beispielen schrittweise an einem Bundle der Nutzerwelten RCP durchgeführt und auf ihren Nutzen für eine Migration des gesamten Programms bewertet.

Cu–Co-based model catalysts were prepared by a sophisticated alkali-free synthesis method and tested in the conversion of synthesis gas to higher alcohols. MoO3-coated alumina was used as the support, providing both high specific surface area and strongly interacting sites for the deposition of the active metals. A bulk Cu/Co ratio of ~2 was found to be most suitable in terms of activity and product distribution. Surface enrichment of Mo for all samples was observed by XPS, which significantly influenced the performance of the catalysts. Mo was found to be both a structural and a chemical promoter. Strong metal–support interactions were further achieved by modification of alumina with magnesia. With 12 wt% Mg incorporated, the catalysts showed 40% total oxygenate selectivity including 11% selectivity to ethanol.
Die Studie des Competence Center Food & Retail (CCFR) der Cologne Business School (CBS) ermittelt Erfolgsfaktoren, Konsumententypen und Handlungsempfehlungen für den Online-Handel mit Lebensmitteln in Deutschland. Grundlage der vorliegenden Studie ist eine im Sommer 2014 durchgeführte onlinebasierte Verbraucherbefragung zum Thema „Online-Kauf von Lebensmitteln“.
eFood in Deutschland
(2015)
Im Vergleich zu „Pionierbranchen“ wie Mode oder Medien steht der Online-Handel mit Lebensmitteln erst am Anfang. Dabei kann dieser zu einem Wettbewerbsvorteil werden – wenn der Handel es richtig angeht. Auf der anderen Seite steht das Risiko einer strategischen Falle, d.h. es wird unter Umständen aufgrund der Widerstände beim Verbraucher nur ein Nischenmarkt bedient, der eine geringe Profitabilität aufweist. Im Spannungsfeld „Marktpotenzial auf Handelsseite“ vs. „Zurückhaltung beim Verbraucher“ rücken dabei Fragen der Kommunikationspolitik im Online-Lebensmittelhandel in den Fokus. Für eine erfolgreiche Umsetzung stellt eine eindeutige Typologie eine notwendige Basis dar, um die konkreten Bedürfnisse potenzieller Konsumenten anzusprechen. Ein Engagement im eFood-Bereich ist daher als Investition in die zukünftige Entwicklung der Märkte und ihrer Zielgruppen zu betrachten. Although online trading in the food sector is still in early stages, it may become a competitive edge – if retailers go about it the right way. On the other hand, due to consumer resistance, there is the risk of serving only a niche market, which cannot be maintained in terms of profitability. Therefore, a stronger focus on communication policies is needed. Engaging in the eFood sector finally has to be seen as an important investment into future markets and their target groups.

The working paper at hand assumes that differences of innovativeness of different countries can be explained to a certain extent by cultural differences. Thus, the paper deals with the research question of which cultural dimensions have an influence on national innovativeness. Previous research mainly uses the Hofstede-dimensions to describe cultural differences and often focuses on single parameters to describe national innovativeness (e.g. number of patents per capita). This paper, instead, uses the dimensions of the GLOBE-study which builds on the findings of Hofstede but is more up-to-date and comprehensive and uses two innovation indexes – the Global Innovation Index (GII) and the Innovation Union Scoreboard (IUS) – to describe national innovativeness. The authors use correlation analysis to find relationships between the GLOBEdimensions and the innovation indexes. They find positive correlations of innovativeness (both indexes) to Future Orientation (practice scale), Gender Egalitarianism (value scale), Human Orientation (value scale) and Uncertainty Avoidance (practice scale) as well as negative correlations to In-Group Collectivism (practice scale), Future Orientation (value scale) and Uncertainty Avoidance (value scale). Some of the findings are contrary to existing hypotheses, e.g. only a weak negative correlation of Power Distance to one of the indexes. Furthermore the findings show significant differences between practice scales and value scales, especially concerning Future Orientation and Uncertainty Avoidance which deserve further examination. Overall it can be concluded that culture has an impact on national innovativeness. The different cultural dimensions of the GLOBE-study show a multi-faceted interrelationship between culture and innovation. To come to a concise answer for the question which dimensions affect national innovativeness in which way additional research will be necessary.
