In this paper, we introduce a framework to identify domain specific use cases for smart glasses in the domain of logistics services. We further present and evaluate our framework through its application in a single case study in a wholesale warehouse. We contribute to theory and practice by presenting an approach to identify, define and describe application scenarios for the adoption of smart glasses in the logistics domain, and by enriching the current body of knowledge on digitalization, service support systems and wearables. Therefore, our research falls into line with the second topic. We directly address current challenges in logistics, one of Germany’s major economic sectors, regarding the implementation of new or advanced services with smart glasses. The presented case study is embedded in the digitalization project Glasshouse. The processes of two logistics services providers are the main research subjects in this project. In contrast to this, we focus on a third logistic service provider in this paper, to evaluate the transferability of our findings.
The development of augmented reality glasses is still ongoing and faces barriers in diffusion and concerns about their impact on users, organizations and society. The study aims to find sufficient solutions for this struggling digital innovation and to provide guidance for the implementation of augmented reality glasses in design-oriented projects. During a 3-year consortium research, acceptance and privacy have been identified as major phenomena that influence the adoption of augmented reality glasses in the logistics domain. To forge ahead digital innovation research, the focus of the presented research lies on the diffusion of this technology with design knowledge for the development of augmented reality glasses-based systems. Evidence and artifacts contribute to the still limited knowledge of system design based on augmented reality glasses from a domain-specific instantiation and an implementation framework.
A structured hospital discharge management process can lead to a smoother transition to aftercare. In practice, providing continuity of nursing care after a stationary hospital stay is accompanied by numerous challenges. The presented study aims to point out the use cases and requirements for an IT system supporting the diverse tasks of the participating actors. Within the scope of a multi-method research design, the authors conducted and analysed stakeholder interviews, a shadowing, a systematic literature search and statutes in order to gain the presented results. This publication presents 37 requirements, grouped to 14 use cases. A process model in BPMN visualises the discharge management process. Further, the authors derived implications for practice and research. These can be used for the development, classification and assessment of IT systems. Therefore, this publication provides a significant contribution to the development of socio-technical systems within the health care domain.
Sustainability is a growing megatrend in our society entailing an increasing importance of sustainable consumption. Consumers associate sustainable products with ecological and regional production including a high credibility. In order to take advantage of this trend manufacturers of sustainable foods must communicate the sustainability of their products via packaging and displays at the point of sale. The objective of this article is to examine how the design of display elements succeeds in conveying sustainability for a new organic juice. In addition, the perception of individual design elements of sustainable products is determined. To this end, a field study was carried out in a supermarket combining eye-tracking technology with a survey of 32 customers. At the entrance, customers were asked to buy a variety of the newly introduced "Emsländer" organic juice, and then participate in the survey. The results demonstrate that customers with a positive attitude towards sustainable food fixate individual display elements referring to sustainability components for longer and remember product features better. Hence, the positive attitude towards sustainable food results in a higher visual attention at the point of sale. These findings provide recommendations for the design of the display.
Vanadium carbide (VC) reinforced FeCrVC hardfacings have become important to improving the lifetime of tools suffering abrasive and impressive loads. This is because the microstructural properties of such hardfacings enable the primary VCs to act as obstacles against the penetrating abrasive. Because dilution is supposed to be the key issue influencing the precipitation behaviour of primary carbides during surfacing, the development of deposit welding processes exhibiting a reduced thermal impact, and hence lower dilution to the base material, is the primary focus of the current research. By inserting an additional hot wire in the melt, an approach was developed to separate the material and energy input during gas metal arc welding (GMAW) and hence realised low dilution claddings. The carbide content could be increased, and a grain refinement was observed compared with conventional GMAW. These effects could be attributed to both the reduced dilution and heterogeneous nucleation.
Seit Jahren ist die steuerliche Behandlung von Aufwendungen für ein häusliches Arbeitszimmer ein immer wiederkehrendes Thema in der Fachliteratur. Auch zahlreiche Auseinandersetzungen mit dem Finanzamt resultieren aus der (Nicht-)Berücksichtigung dieser Aufwendungen. In der Vergangenheit wurden bereits etliche Gerichtsurteile zu unterschiedlichen Fallkonstruktionen aus diesem Bereich gesprochen. Momentan hat das Thema erneut an Aktualität gewonnen. So arbeitet aufgrund der derzeit herrschenden Pandemie eine große Anzahl an Steuerpflichtigen (erstmals) im Homeoffice und wendet sich ratsuchend mit Fragen zu den entsprechenden steuerlichen Folgen an ihre steuerlichen Berater. Der vorliegende Beitrag beschäftigt sich unter Heranziehung einschlägiger Urteile mit der steuerlichen Behandlung von Aufwendungen für ein häusliches Arbeitszimmer, nimmt Stellung zu den Möglichkeiten der steuerlichen Abzugsfähigkeit in der aktuellen besonderen Situation, analysiert diese kritisch und formuliert konkrete Handlungsempfehlungen.
Fridays Lectures for Future
(2020)
Die Bewegung "Fridays for Future" hat der Umwelt- und der Nachhaltigkeitsdiskussion neuen Schwung gegeben. Schüler demonstrieren für mehr Umweltschutz. Im Mittelpunkt steht die CO2-Reduzierung als Gegenmaßnahme zum weltweit erkennbaren Klimawandel und seinen Folgen. Zur Unterstützung der Diskussionen um verstärkten Umwelt- und Klimaschutz sowie mehr Nachhaltigkeit werden in diesem Band "Fridays Lectures for Future" fünfzehn Lektionen zum Themenbereich Umwelt und Nachhaltigkeit vorgestellt. Es handelt sich um eine Auswahl von Themen, die selbstverständlich nicht das ganze, sehr umfangreiche Problemfeld widerspiegeln können. Es bleibt die Hoffnung, dass die ausgewählten Themenbereiche für den interessierten Leser Ansporn zu einem intensiven Selbststudium sind, um sich weitere Themen zu erschließen.
