This paper describes the robots TIAGo and Lisa used by team homer@UniKoblenz of the University of Koblenz-Landau, Germany, for the participation at the RoboCup@Home 2018 in Montreal, Canada. Further this paper serves as qualification material for the RoboCup-@Home participation in 2018. A special focus is put on novel system components and the open source contributions of our team. This year the team from Koblenz won the biggest annual scientianc robot competition in Montreal in the RoboCup@Home Open Platform track for the third time and also won the RoboCup@Home German Open for the second time. As a research highlight a novel symbolic imitation learning approach was demonstrated during the annals. The TIAGo robotic research platform was used for the first time by the team. We have released packages for object recognition, a robot face including speech synthesis, mapping and navigation, speech recognition interface via android and a GUI. The packages are available (and new packages will be released) on http://wiki.ros.org/agas-ros-pkg. Further information can be found on our project page http://homer.uni-koblenz.de.

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.
Digital happiness
(2016)
Emotions in the digital world gain more and more importance by the accelerating digitalization of recent years. In everyday life as well as professional and educational environments, the use of media is almost inescapable. This work takes a closer look to the still relatively unknown topic, “Digital Happiness“. In the literature emotions in the digital world are studied increasingly, but concerning the topic of “Digital Happiness” there are not many insights.
In this research the differences between communicating emotions through digital media and face-to-face communications, as well as their impacts, are investigated. The perception and expression of emotions in the real and digital world are considered. Furthermore, a first definition of “Digital Happiness” and a model with the associated determinants that influence “Digital Happiness” is developed.
To achieve these goals, a literature analysis by the method of Webster & Watson (2002) is performed. Therefore, 15 articles are selected and analyzed in more detail to illustrate the current state of research. These articles are organized into a concept matrix. In addition, special phenomena, such as Quantified Self, are closely considered in order to determine other factors. Based on the literature analysis, a qualitative study by the method of Mayring (2014) is performed. It is developed into an interview guideline that serves as the basis for the investigation of the established determinants of the literature analysis. This is confirmed or refuted by 30 interviews with users of information and communication technologies. With the help of the interviews, a large part of the determinants in the literature can be confirmed. Moreover, some new determinants are identified. These results are included into the final model. This model provides a basis for further research in the field of “Digital Happiness“. Finally, different implications for research and practice are found, which reveal the need of further research.
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.
Die vorliegende Arbeit bildet den Abschluss eines Forschungspraktikums von Studierenden der Masterstudiengänge Informationsmanagement und Wirtschaftsinformatik unter Betreuung der wissenschaftlichen Mitarbeiterin Daniela Simić-Draws und von Prof. Dr. Rüdiger Grimm. Eine wesentliche Vorlage zu dieser Arbeit war ein Vorgehensmodell zur Sicherheitsanalyse von Geschäftsprozessen, das von D. Simić-Draws im Rahmen ihrer Dissertation erarbeitet wird und zu dessen laufender Verbesserung dieses studentische Forschungspraktikum wertvolle Hinweise liefern konnte. Als Anwendungsbeispiel wurden die sicherheitskritischen Prozesse "Kommunalwahl" und "Geldauszahlung am Bankautomaten" gewählt, weil die Arbeitsgruppe von Prof. Grimm in diesen beiden Anwendungen aus vorhergehender wissenschaftlicher Arbeit Erfahrung gesammelt hat. Insbesondere zum Anwendungsbeispiel "Kommunalwahl" hatte sich dankenswerterweise das Ordnungsamt Koblenz, das für die Kommunalwahlen zuständig ist, unter aktiver Mithilfe ihres Leiters Dirk Urmersbach zur Zusammenarbeit angeboten, so dass dieser Geschäftsprozess wirklichkeitsnah untersucht werden konnte.
