While industrialized countries are becoming service economies, all countries are becoming global. As competition becomes more global, understanding and accommodating the needs of international customers with different cultural backgrounds has become increasingly important. This study highlights cross-cultural perceptions of service problems in the tourist industry.
Nowadays, we input text not only on stationary devices, but also on handheld devices while walking, driving, or commuting. Text entry on the move, which we term as nomadic text entry, is generally slower. This is partially due to the need for users to move their visual focus from the device to their surroundings for navigational purposes and back. To investigate if better feedback about users' surroundings on the device can improve performance, we present a number of new and existing feedback systems: textual, visual, textual & visual, and textual & visual via translucent keyboard. Experimental comparisons between the conventional and these techniques established that increased ambient awareness for mobile users enhances nomadic text entry performance. Results showed that the textual and the textual & visual via translucent keyboard conditions increased text entry speed by 14% and 11%, respectively, and reduced the error rate by 13% compared to the regular technique. The two methods also significantly reduced the number of collisions with obstacles.
Das Thema Querdenken ist so aktuell, spannend und interessant, dass sich Prof. Dr. Jens Böcker von der Hochschule Bonn-Rhein-Sieg nach unseren ersten Gesprächen dazu entschlossen hat, eine Projektarbeit für seine Studenten zu diesem Thema zu vergeben. Prof. Dr. Böcker ist Professor im Fachbereich Wirtschaftswissenschaften für BWL mit dem Schwerpunkt Marketing. Das „Forschungsprojekt Querdenken“ wurde von einer Gruppe Studenten um Manuel Hammes als Projektleiter im Sommersemester 2010 bei Prof. Dr. Böcker durchgeführt.
Aufgrund der zunehmenden Behandlung von sozialen Netzwerken in den Medien war es das Ziel der Arbeit das Geschäftsmodell von sozialen Netzwerken näher zu analysieren. Die Arbeit zeigt, dass soziale Online-Netzwerke zu den Diensten im Internet gehören, die zwar schon länger existieren, ihren eigentlichen Durchbruch aber erst in den letzten Jahren erlebten. Zu Beginn als reine Kommunikationsplattform genutzt, werden sie heute zur allgemeinen Freizeitgestaltung verwendet und integrieren sich zunehmend in das alltägliche Leben. Die Arbeit beschäftigt sich mit den ökonomischen Besonderheiten von sozialen Online-Netzwerken. Analysiert werden Netzwerkeffekte, Angebots- und Nachfrageverhalten, kritische Masse-Phänomene, Tippy markets, Netzwerkgesetze, Lock-In-Effekte und Wechselkosten. Es wird untersucht, ob und inwieweit sich hinter den sozialen Online-Netzwerken auch klar erkennbare Geschäftsmodelle verbergen. Aufbauend auf einer kritischen Auseinandersetzung mit der Vielfalt existierender Geschäftsmodelle erfolgt die Entwicklung eines eigenen tragfähigen Ansatzes. Auf dieser Basis wird eine Analyse existierender Online-Netzwerke und eine Beurteilung ihres Innovationsgrades vorgenommen.
Hochschulbibliotheken haben heutzutage neben der traditionellen Aufgabe der Literaturversorgung und Informationsversorgung auch die Aufgabe, über ihre Website im Internet präsent zu sein und sich dort als zentraler Informationsanbieter zu positionieren. Die Webauftritte haben dabei die Funktionen als Zugangspunkt und Vermittlungsstelle für Informationen sowie als Werbemittel bzw. Instrument der Öffentlichkeitsarbeit. Im Hinblick auf die immer stärkere Benutzerorientierung der Bibliotheken werden die Webangebote von fünf Universitätsbibliotheken und einer Fachhochschulbibliothek nach diversen Kriterien analysiert: es wird herausgearbeitet, welche Inhalte auf den Websites zu finden sind, die Struktur wird näher betrachtet, ebenso wie die Navigationsmöglichkeiten, die Sprache und Textgestaltung und das Design.

Green IT (Green IS, Green ICT) is a concept of saving energy consumption to reduce IT costs. A current survey shows that only few companies in German speaking countries consider this aspect in their daily business. This is important facing the current situation of attempts of cost saving during the current economic crisis worldwide. This paper introduces into Green IT and presents an IT management and controlling concept. Then the main results of a currently presented survey are used to modify the concept. Finally an agenda for future research is given

This study presents the findings of a quantitative study on the use of Open Educational Resources (OER) and Open Educational Practices (OEP) in Higher Education and Adult Learning Institutions. The study is based on the results of an online survey targeted at four educational roles: educational policy makers; institutional policy makers/managers; educational professionals; and learners. The report encompasses five chapters and four annexes. Chapter I presents the survey and Chapter II discloses the main research questions and models. Chapter III characterises the universe of respondents. Chapter IV advances with a detailed survey analysis including an overview of key statistical data. Finally, Chapter V provides an exploratory in-depth analysis of some key issues: representations, attitudes and uses of OEP. The table of contents and the complete list of diagrams and tables can be found at the end of the report.
This paper addresses special skills, learners in Internet-based learning scenarios need. In self-directed learning scenarios, as most Internet-based learning scenarios are designed, learners bear the responsibility for their learning progress. To ease this task, institutions could prime the learners for the situation which may be quite different to their previous learning experiences. Basing on a Delphi-study, conducted with experts from the e-Learning sector in Germany, Austria, and Switzerland, the basic requirements have been determined.
The roadmap for quality and innovation through open educational practices has been conceived as a number of steps, a conceptual document, which can be used by organisations, leaners or professionals in order to improve their open educational practices. After the development of the core concept of the OPAL project, the guidelines for OEP, it became clear that these guidelines, would have to play an important part on the roadmap exercise, because they represent the very essence of how to foster and stimulate open educational practices. The roadmap therefore is meant to be an instrument, a tool which helps the different stakeholders to use the guidelines for their own context and purpose.
