In order to enhance the company’s appeal for potential employees and improve the satisfaction of already salaried workers, it is necessary to offer a variety of work-life balance measures. But as their implementation causes time and financial costs, a prioritization of measures is needed. To express a recommendation for companies, this study is led by the questions if there are work-life balance measures which have more impact on employee satisfaction than others, how big the relative impact of work-life balance measures on job satisfaction in comparison to other work and private life variables is, if there is a relation between the effectiveness of measures and their use and if there is a difference between the measures which are most important from the employees’ perspective and the companies’ offers. These questions are formulated in eight research hypotheses which are examined in a quantitative research design with online survey data from 289 employees of fifteen different German companies. The formation of a hierarchy of the effectiveness of measures towards job satisfaction as well as the investigation of the relative impact in comparison to other variables is performed using a multiple regression analysis, whilst the differences between employees’ expectations and the availability of offers are examined with t-tests. Support in childcare, support in voluntary activities and teambuilding events have a significantly higher impact on job satisfaction than other work-life balance measures, and their potential use is higher than the actual use which leads to the conclusion that there is yet potential for companies to improve their employees’ satisfaction by implementing these measures. In addition, flexible work hours, flexible work locations and free time and overtime accounts are the most important measures from the employees’ point of view and already widely offered by the surveyed companies. In general, the overall use of the available measures and the quantity of offered measures are more important with regard to job satisfaction than the specific kind of measure. In addition, work-life balance measures are more important towards job satisfaction for younger people.

Despite widespread plans of big companies like Amazon and Google to develop unmanned delivery drones, scholarly research in this field is scarce, especially in the information systems field. From technical and legal perspectives, drone delivery in last-mile scenarios is in a quite mature state. However, estimates of user acceptance are varying between high skepticism and exaggerated optimism. This research follows a mixed method approach consisting both qualitative and quantitative research, to identify and test determinants of consumer delivery drone service adoption. The qualitative part rests on ten interviews among average consumers, who use delivery services on a regular basis. Insights gained from the qualitative part were used to develop an online survey and to assess the influence of associated risks on adoption intentions. The quantitative results show that especially financial and physical risks impede drone delivery service adoption. Delivery companies who are currently thinking about providing a delivery drone service may find these results useful when evaluating usage behaviors in the future market for delivery drones.

Bei dem für dieses Schutzprofil (engl. "Protection Profile" im Folgenden PP genannt) herangezogenen Evaluationsgegenstand (im Folgenden EVG genannt) handelt es sich um einen Router, der einen Schutz gegen Online-Überwachung bietet. Der EVG-Typ ist hierbei ein handelsüblicher Internet-Router, der in Privathaushalten und kleineren Firmen eingesetzt wird. Der EVG umfasst den gesamten Router, so dass sowohl die Hardwarekomponenten als auch die Softwarekomponenten betrachtet werden. Es ist dabei irrelevant, ob es ein Modell mit integriertem Breitband-Modem ist oder ob dieses separat angeschlossen ist.

Six and Gimmler have identified concrete capabilities that enable users to use the Internet in a competent way. Their media competence model can be used for the didactical design of media usage in secondary schools. However, the special challenge of security awareness is not addressed by the model. In this paper, the important dimension of risk and risk assessment will be introduced into the model. This is especially relevant for the risk of the protection of personal data and privacy. This paper will apply the method of IT risk analysis in order to select those dimensions of the Six/Gimmler media competence model that are appropriate to describe privacy aware Internet usage. Privacy risk aware decisions for or against the Internet usage is made visible by the trust model of Mayer et al.. The privacy extension of the competence model will lead to a measurement of the existing privacy awareness in secondary schools, which, in turn, can serve as a didactically well-reasoned design of Informatics modules in secondary schools. This paper will provide the privacy-extended competence model, while empirical measurement and module design is planned for further research activities.

In this article we analyze the privacy aspects of a mobile sensor application used for recording urban travel patterns as part of a travel-survey service. This service has been developed and field-tested within the Live+Gov EU Project. The privacy analysis follows a structured approach established in. Eight privacy recommendations are derived, and have already led to corresponding enhancements of the travel-survey service.

Dieses Dokument legt den Standard für die Transformation von grUML-Schemas (GraphUML, [BHR+09]) nach XSD (XML Schema Definition) fest und ist im Rahmen des Arbeitspakets 5.2 "Prototypische SOAMIG-Parser und -Unparser realisieren" im SOAMIG-Projekt entstanden. Das Ziel ist der Austausch von TGraphen (typisierten, attributierten, angeordneten, gerichte Graphen [ERW08]) über XML-Dokumente. Zur Spezifikation des Austauschformats wird XSD eingesetzt. Dies erlaubt eine Validierung der XML-Instanzen auf syntaktischer Ebene. Der Ausgangspunkt ist ein gegebenes Schemas in grUML-Notation1, welches nach XSD transformiert werden soll. Mit der generierten XSD existiert ein Beschreibungsmittel für Graph-Instanzen in XML. Die dadurch beschriebenen XML-Dokumente sind flach, d.h. alle Elemente sind direkt dem root-Element untergeordnet.

Im Gesundheitswesen geht es nicht nur um die Vertraulichkeit von Patientendaten, sondern auch um ihre Integrität, von der die richtige Behandlung und Pflege des Patienten abhängen. Eine Maßnahme zur Absicherung eines Krankenhausinformationssystems (KIS) gegen unautorisierte Angreifer ist eine flexibel organisierte Zugriffskontrolle zum Schutz der patientenbezogenen Daten. Dieser Artikel beschreibt das Konzept einer rollenbasierten Zugriffskontrolle (RBAC - Role Based Access Control) und seine Einsatzmöglichkeiten im Gesundheitswesen.

This paper describes the development of security requirements for non-political Internet voting. The practical background is our experience with the Internet voting within the Gesellschaft für Informatik (GI - Informatics Society) 2004 and 2005. The theoretical background is the international state-of-the-art of requirements about electronic voting, especially in the US and in Europe. A focus of this paper is on the user community driven standardization of security requirements by means of a Protection Profile of the international Common Criteria standard.

This is the 10th international workshop for technical, economic, and legal aspects of business models for virtual goods incorporating the 8th ODRL community group meeting. This year we did not call for completed research results, but we invited PhD students to present and discuss their ongoing research work. In the traditional international group of virtual goods and ODRL researchers we discussed PhD research from Belgium, Brazil, and Germany. The topics focused on research questions about rights management in the Internet and e-business stimulation. In the center of rights management stands the conception of a formal policy expression that can be used for human readable policy transparency, as well as for machine readable support of policy conformant systems behavior up to automatic policy enforcement. ODRL has proven to be an ideal basis for policy expressions, not only for digital copy rights, but also for the more general "Policy Awareness in the World of Virtual Goods". In this sense, policies support the communication of virtual goods, and they are a virtualization of rules-governed behavior themselves.
