Die vorliegende Arbeit untersucht die Wirkung von Spitzenführungspersonal-Fotos. Sie liefert Antworten auf die Frage, welche Mimik und welche Gestik auf solchen Fotos bei den betrachtenden Personen die positivste Wirkung erzeugt und welche Wirkungsunterschiede existieren, in Abhängigkeit davon, wer das Foto betrachtet und in Abhängigkeit davon, ob auf dem Foto eine weibliche oder männliche Person zu sehen ist.
Beim Betrachten von Portraitfotos entstehen bei Menschen automatisch und unbewusst Vorstellungen über die Eigenschaften der abgebildeten Person, so genannte implizite Persönlichkeitstheorien.
Die Untersuchung wurde als Online-Befragung in Form einer Bildbewertungsstudie durchgeführt. Als Stimulusmaterial wurden jeweils 16 Fotos einer weiblichen und einer männlichen Spitzenführungskraft produziert, welche unterschiedliche Kombinationen aus Gestiken und Mimiken zeigten, die nach den Attributen Glaubwürdigkeit, Sympathie, Attraktivität, Kompetenz und Entschlossenheit bewertet wurden.
Weibliche Spitzenführungskräfte wirken am positivsten, wenn sie eine zugewandte Gestik zeigen. Besonders glaubwürdig wirken sie, wenn sie dazu ein Zahnlächeln zeigen. Kompetenz und Entschlossenheit wird bei weiblichen Spitzenführungskräften am stärksten durch eine Kombination aus einem Schmunzeln und einer zugewandten Gestik vermittelt – Attraktivität und Sympathie durch eine Kombination aus Lachen und einer zugewandten Gestik. Kompetenz und Entschlossenheit werden bei männlichen Spitzenführungskräften ebenfalls durch eine Kombination aus Schmunzeln und einer zugewandten Gestik am stärksten vermittelt. Glaubwürdigkeit wird durch eine Kombination aus Schmunzeln und einer vorgebeugten Gestik am stärksten vermittelt – Attraktivität und Sympathie durch eine Kombination aus Lachen und einer vorgebeugten Gestik.
BYOD Bring Your Own Device
(2013)
Using modern devices like smartphones and tablets offers a wide variety of advantages; this has made them very popular as consumer devices in private life. Using them in the workplace is also popular. However, who wants to carry around and handle two devices; one for personal use, and one for work-related tasks? That is why “dual use”, using one single device for private and business applications, may represent a proper solution. The result is “Bring Your Own Device,” or BYOD, which describes the circumstance in which users make their own personal devices available for company use. For companies, this brings some opportunities and risks. We describe and discuss organizational issues, technical approaches, and solutions.
Regional Innovation Systems describe the relations between actors, structures and infrastructures in a region in order to stimulate innovation and regional development. For these systems the collection and organization of information is crucial. In the present paper we investigate the possibilities to extract information from websites of companies. First we describe regional innovation systems and the information types that are necessary to create them. Then we discuss the possibilities of text mining and keyword extraction techniques to extract this information from company websites. Finally, we describe a small scale experiment in which keywords related to economic sectors and commodities are extracted from the websites of over 200 companies. This experiment shows what the main challenges are for information extraction from websites for regional innovation systems.
Schriftliche Nachlässe werden in deutschen Bibliotheken in einer langen Tradition ge-sammelt und verwaltet. In der vorliegenden Bachelorarbeit werden die Besonderheit von schriftlichen Nachlässen und die Entwicklung der Nachlassbearbeitung erläutert. Zunächst werden zur Einführung in die Thematik Begriffsdefinitionen, die Bedeutung sowie die Entwicklungen in der Bearbeitung von Nachlässen dargelegt. An die Einführungen werden die Frage nach der Zuständigkeit zur Übernahme eines Nachlasses und der damit zusammenhängende Kompetenzstreitfall angeknüpft. Im Folgenden wird die Erwerbung thematisiert. Dazu werden die verschiedenen Erwerbungsarten vorgestellt und die möglichen rechtlichen Probleme in der Erwerbung aufgezeigt. Die Bearbeitung von Nachlässen wird anhand von Kassation, Ordnung, Erschließung und Maßnahmen zur Bestandserhaltung dargestellt. Die Thematik der schriftlichen Nachlässe wird mit Aspekten und Fragen der Nutzung abgeschlossen. Der theoretischen Abhandlung folgt die Dokumentation der Ordnung und Erschließung der Fotografien-Sammlung aus dem Nachlass von Robert Michel und Ella Bergmann-Michel, die mit der Vorstellung des Künstlerpaares und dessen Nachlass beginnt. Danach folgt die Erläuterung der praktischen Aufgabe im Hinblick auf Zielsetzung, Ausgangssituation, Vorbereitung und Durchführung. Abgeschlossen wird die Dokumentation mit Empfehlungen für die zukünftige Bearbeitung der Fotografien und des gesamten Nachlasses.
Distributional semantics tries to characterize the meaning of words by the contexts in which they occur. Similarity of words hence can be derived from the similarity of contexts. Contexts of a word are usually vectors of words appearing near to that word in a corpus. It was observed in previous research that similarity measures for the context vectors of two words depend on the frequency of these words. In the present paper we investigate this dependency in more detail for one similarity measure, the Jensen-Shannon divergence. We give an empirical model of this dependency and propose the deviation of the observed Jensen-Shannon divergence from the divergence expected on the basis of the frequencies of the words as an alternative similarity measure. We show that this new similarity measure is superior to both the Jensen-Shannon divergence and the cosine similarity in a task, in which pairs of words, taken from Wordnet, have to be classified as being synonyms or not.
Background: Physician-rating websites are currently gaining in popularity because they increase transparency in the health care system. However, research on the characteristics and content of these portals remains limited.
Objective: To identify and synthesize published evidence in peer-reviewed journals regarding frequently discussed issues about physician-rating websites.
Methods: Peer-reviewed English and German language literature was searched in seven databases (Medline (via PubMed), the Cochrane Library, Business Source Complete, ABI/Inform Complete, PsycInfo, Scopus, and ISI web of knowledge) without any time constraints. Additionally, reference lists of included studies were screened to assure completeness. The following eight previously defined questions were addressed: 1) What percentage of physicians has been rated? 2) What is the average number of ratings on physician-rating websites? 3) Are there any differences among rated physicians related to socioeconomic status? 4) Are ratings more likely to be positive or negative? 5) What significance do patient narratives have? 6) How should physicians deal with physician-rating websites? 7) What major shortcomings do physician-rating websites have? 8) What recommendations can be made for further improvement of physician-rating websites?
Results: Twenty-four articles published in peer-reviewed journals met our inclusion criteria. Most studies were published by US (n=13) and German (n=8) researchers; however, the focus differed considerably. The current usage of physician-rating websites is still low but is increasing. International data show that 1 out of 6 physicians has been rated, and approximately 90% of all ratings on physician-rating websites were positive. Although often a concern, we could not find any evidence of "doctor-bashing". Physicians should not ignore these websites, but rather, monitor the information available and use it for internal and ex-ternal purpose. Several shortcomings limit the significance of the results published on physician-rating websites; some recommendations to address these limitations are presented.
Conclusions: Although the number of publications is still low, physician-rating websites are gaining more attention in research. But the current condition of physician-rating websites is lacking. This is the case both in the United States and in Germany. Further research is necessary to increase the quality of the websites, especially from the patients’ perspective.
Of late, decrease in mineral oil supplies has stimulated research on use of biomass as an alternative energy source. Climate change has brought problems such as increased drought and erratic rains. This, together with a rise in land degeneration problems with concomitant loss in soil fertility has inspired the scientific world to look for alternative bio-energy species. Euphorbia tirucalli L., a tree with C3/CAM metabolism in leaves/stem, can be cultivated on marginal, arid land and could be a good alternative source of biofuel.
We analyzed a broad variety of E. tirucalli plants collected from different countries for their genetic diversity using AFLP. Physiological responses to induced drought stress were determined in a number of genotypes by monitoring growth parameters and influence on photosynthesis. For future breeding of economically interesting genotypes, rubber content and biogas production were quantified.
Cluster analysis shows that the studied genotypes are divided into two groups, African and mostly non-African genotypes. Different genotypes respond significantly different to various levels of water. Malate measurement indicates that there is induction of CAM in leaves following drought stress. Rubber content varies strongly between genotypes. An investigation of the biogas production capacities of six E. tirucalli genotypes reveals biogas yields higher than from rapeseed but lower than maize silage.
