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.

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 2019 in Sydney,
Australia. We ended up first at RoboCup@Home 2019 in the Open Platform
League and won the competition in our league now three times
in a row (four times in total) which makes our team the most successful
in RoboCup@Home. We demonstrated approaches for learning from
demonstration, touch enforcing manipulation and autonomous semantic
exploration in the finals. A special focus is put on novel system components
and the open source contributions of our team. We have released
packages for object recognition, a robot face including speech synthesis,
mapping and navigation, speech recognition interface, gesture recognition
and imitation learning. The packages are available (and new packages
will be released) on http://homer.uni-koblenz.de.

This paper describes the robot Lisa used by team homer@UniKoblenz of the University of Koblenz Landau, Germany, for the participation at the RoboCup@Home 2017 in Nagoya, Japan. A special focus is put on novel system components and the open source contributions of our 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

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.

Im Rahmen dieser Arbeit wird der Einfluss des Wahlszenarios auf die Geheimheit und Öffentlichkeit der Wahl herausgearbeitet. Ein Wahlszenario wird durch seine Wahlform und die verwendete Wahltechnik bestimmt. Bei der Wahl-form kann zwischen einer Präsenz- und einer Fernwahl unterschieden werden. Bei der Wahltechnik zwischen der Papier- und der elektronischen Wahl. Mit der Papier-Präsenzwahl, der Briefwahl (Papier-Fernwahl) und der Internetwahl (elektronische Fernwahl) werden drei prominente Wahlszenarien und ihr Einfluss auf Geheimheit, Privatheit und Öffentlichkeit untersucht.

Die Reputation von Unternehmen ist einer zunehmenden Gefahr ausgesetzt, die sich aus der (unreflektierten) Nutzung sozialer Netzwerke durch die eigenen Mitarbeiter ergibt. Die Treiber und Hemmnisse eines solchen Nutzerverhaltens von Arbeitnehmern in sozialen Netzwerken wurden bislang nur unzureichend erforscht. Der vorliegende Beitrag untersucht unter Verwendung der Boundary Theorie am Beispiel der Plattform Facebook, inwieweit die Persönlichkeitsmerkmale Neurotizismus und Extraversion, die Organisationsidentifikation und die Unternehmensreputation ein zustimmendes Verhalten von Nutzern begünstigen. Eine experimentelle Online-Studie mit 494 Probanden zeigt, dass insbesondere eine hohe Unternehmensreputation und Organisationsidentifikation zu einem erhöhten zustimmenden Verhalten führen.

Digital happiness
(2016)
Emotionen in der digitalen Welt gewinnen durch die immer weiter voranschreitende Digitalisierung in den vergangenen Jahren mehr an Bedeutung. Sowohl im Alltag als auch im Berufs- und Bildungsumfeld ist der Einsatz von Medien fast unumgänglich. In dieser Arbeit wird das noch relativ unbeachtete Thema „Digital Happiness“ genauer betrachtet. In der Literatur werden Emotionen in der digitalen Welt verstärkt untersucht, aber gerade zu dem Thema „Digital Happiness“ gibt es bisher noch nicht viele Erkenntnisse.
In diesem Forschungspraktikum werden die Unterschiede in der Kommunikation von Gefühlen in der computergestützten Kommunikation und der face-to-face Kommunikation, sowie welchen Einfluss diese haben, näher untersucht. Aber auch die Wahrnehmung und Äußerung von Emotionen in der realen und digitalen Welt werden betrachtet. Es wird eine erste Definition von „Digital Happiness“ erarbeitet und ein Modell mit den zugehörigen Determinanten, welche „Digital Happiness“ beeinflussen, entwickelt.
Um diese Ziele zu erreichen, wird eine Literaturanalyse nach der Methode von Webster & Watson (2002) durchgeführt. Hierfür werden 15 Artikel ausgewählt und genauer analysiert, um den aktuellen Stand der Forschung darzustellen. Diese werden in einer Konzeptmatrix eingeordnet. Außerdem werden besondere Phänomene, wie z.B. Quantified Self, näher betrachtet, um weitere Einflussfaktoren feststellen zu können. Basierend auf der Literaturanalyse wird eine qualitative Untersuchung nach Mayring (2014) durchgeführt. Es wird ein Interviewleitfaden entwickelt, der als Grundlage für die Untersuchung der festgestellten Determinanten der Literaturanalyse dient. Diese sollen durch 30 Interviews mit Nutzern von Informations- und Kommunikationstechnologien bestätigt oder widerlegt werden.
Mit Hilfe der durchgeführten Interviews lässt sich ein Großteil der Determinanten aus der Literatur bestätigen. Es wurden auch einige neue Determinanten festgestellt. Diese Ergebnisse werden in das abschließende Modell eingearbeitet. Dieses Modell bietet eine Grundlage für weitere Forschungen im Bereich „Digital Happiness“. Schlussendlich werden noch verschiedene Implikationen für die Forschung und Praxis festgestellt, welche weiteren Forschungsbedarf erkennen lassen.

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.
