Abstract
The resolution of current head-mounted displays leads to poor readability of text inrealistic virtual reality (VR) simulations. This results in unnatural user behavior. Here, three approaches for improving the readability of text in VR have been investigated:1) constantly magnifying a part of the screen (version "lens"), 2) magnifying sceneelements such as signs depending on the gaze direction (version "magnify") and3) augmenting the scene by adding floating texts (version "AR"). These approaches havebeen implemented as prototypes and tested by twelve users, using a virtual supermarketas an exemplary VR scene. The participants filled out a questionnaire, rating theirexperience with the different approaches. Additionally, the time required for readinggiven texts (price tags) has been measured and compared for each approach. With theAR version, the reading time was significantly shorter than the reading time without anyaids. The other versions offered no advantages. The AR version was also rated best in thequalitative evaluation. However, the other versions offer potential for improvement, which can be addressed in future research.

Abstract
Sustainable operations and sustainable supply chain management (SSCM) have become a highly relevant topic for scientific research and management, as well as policy-making practice. Despite surging growth in extant research, the need for theoretical and conceptual substantiation persists, and large opportunities for further research remain unexploited. This paper responds to the need for a conceptual foundation and, therefore, aims at providing a structured agenda for future research areas in SSCM. Based on an abductive reasoning approach, SSCM constructs and concepts are gathered from existing literature and recombined into a comprehensive conceptual SSCM framework. Areas and directions for future SSCM research, as suggested in earlier studies, are summarized, positioned in the framework, and outlined to stimulate further SSCM research activities. To overcome the lack of holistic research in the field, sophisticated techniques and integrated systems to support decision-making are required to tackle related issues’ complexity. Therefore, this paper’s contribution lies in the synthesis of state-of-the-art literature to provide a more comprehensive view of SSCM. Researchers may find promising recommendations and a suitable foundation for future studies, while practitioners may find helpful orientation and guidance for decision- and policy-making.

Abstract
Die vorliegende Arbeit liefert einen Beitrag zum näheren Verständnis über die Treiber von Open Innovation in kleineren und mittleren Unternehmen (KMU). Im Vordergrund der Überlegungen steht die Frage, welche Faktoren zur Einführung von Open Innovation in KMU führen. Zur Beantwortung der Forschungsfrage wurde in enger Anlehnung an Drechsler und Natter (2012) ein Modell entwickelt, welches Wettbewerbsintensität, F&E-Intensität und Internationalisierung als zentrale Prädiktoren für Open Innovation betrachtet. Zur Überprüfung des Modells wurden drei Hypothesen formuliert und mittels einer hierarchischen Regressionsanalyse empirisch überprüft. Datenbasis bildet das Mannheimer Innovationpanel 2013. Die Stichprobe umfasst 1.514 innovative KMU mit Sitz in Deutschland. Die empirische Analyse konnte die bisherigen Forschungsergebnisse in weiten Teilen bestätigen, zeigt aber auch gewisse Unterschiede zu bisherigen Erkenntnissen auf. Der F&E-Intensität kommt als Treiber von Open Innovation in KMU der größte Einfluss zu, Internationalisierung besitzt hingegen den geringsten Einfluss. Insgesamt ist jedoch festzustellen, dass durch die drei berücksichtigen Faktoren nur 18,5 Prozent der vorgefundenen Varianz in Bezug auf Open Innovation in KMU erklärt werden können. Das heißt, es sind zukünftig weitere Faktoren für das Verständnis über die relevanten Treiber von Open Innovation in KMU heranzuziehen.
