@article{26870, abstract = {{The article examines the division of labor for everyday food routines of two-parent households depending on their labor force participation. Using data from the representative German Time Use Survey 2001/02 and 2012/13, three different pairs were formed: dual-earner couples, couples with additional female income and male-breadwinner couples Findings show that mother’s employment influences the time used for everyday food routines: It was found that the higher the employment rate of mothers, the less time was spent on food routine activities. Furthermore, the daily time used for everyday food routines was reduced from 2001/02 to 2012/13. The largest reductions were seen in the group of mothers working fulltime. Besides that, fathers were more engaged in meal preparation on the weekends, although the responsibility was the mother’s. In addition, the age and number of children in a household influenced the time used for everyday food routines. However, none of the examined pair constellations can help determine an egalitarian division of everyday food routines. There is still a labor division by gender. Zusammenfassung Der Beitrag untersucht die zeitliche Gestaltung sowie die innerfamiliale Arbeitsteilung des Essalltags von Müttern und Vätern in Paarbeziehungen differenziert nach deren Erwerbsumfang. Die Sekundäranalyse erfolgt auf Basis der repräsentativen Zeitverwendungsdaten 2012/13 und 2001/02, wobei drei Paarkonstellationen untersucht werden: Doppelverdiener-Paare, weibliche Zuverdiener- Paare sowie Paare mit männlichem Familienernährer. Die Analyse des Essalltags zeigt, dass der Erwerbsstatus der Mutter die zeitliche Gestaltung des Essalltags beeinflusst. Je höher dieser ist, desto weniger Zeit wird für die Ernährungsversorgung aufgewendet. Darüber hinaus hat sich die tägliche Zeitverwendung für die Ernährungsversorgung von 2001/02 bis 2012/13 reduziert, wobei die stärksten Einsparungen bei vollzeiterwerbstätigen Müttern zu konstatieren sind. Väter engagieren sich verstärkt am Wochenende bei der Mahlzeitenzubereitung, gleichwohl liegt die Verantwortung insgesamt bei den Müttern. Ebenso beeinflussen Alter und Anzahl der Kinder die Zeitverwendung für die Ernährungsversorgung. Letztlich kann in keiner untersuchten Paarkonstellation eine egalitäre Arbeitsteilung zur Gestaltung des Essalltags festgestellt werden. Vielmehr dominieren relativ ausgeprägte geschlechtsspezifische Arrangements.}}, author = {{Klünder, Nina and Meier-Gräwe, Uta}}, issn = {{2699-2337}}, journal = {{Journal of Family Research}}, pages = {{179--201}}, title = {{{Essalltag und Arbeitsteilung von Eltern in Paarbeziehungen – Eine quantitative Analyse auf Basis der repräsentativen Zeitverwendungsdaten 2012/13 und 2001/02}}}, doi = {{10.3224/zff.v29i2.03}}, year = {{2017}}, } @article{26883, author = {{Meier-Gräwe, Uta and Klünder, Nina}}, journal = {{Familien stärken, Vielfalt ermöglichen.

These microservices are clearly bounded for each other and expose their functionality through, for instance, RESTful application inter- faces. Particularly the clear boundaries between microservices enable the reuse of microservice throughout different projects. Because of the increasing use of microservices, the composition of multiple microservices in service composition becomes a more important task. A challenging area in developing service compo- sitions is that it involves two distinct layers with few junctions. On the one hand, describes a service composition a business process, which involves multiple com- ponents. On the other hand, involves the implementation of a service composition topics like service discovery and message exchange protocols since the microser- vices involved in a service composition are located within a network environment. In this Bachelor’s Thesis, I describe a descriptions language to abstractly describe the business logic of a service composition. Furthermore, I describe a genera- tion process, which compiles this abstract description to a working microservice realizing the specified service composition. In addition to that, I provide an im- plementation of the generation process, as a proof of concept, and test it within a Kubernetes-based cluster environment.}}, author = {{Schürmann, Andreas}}, publisher = {{Universität Paderborn}}, title = {{{Microservice-based Execution Environment for Service Compositions}}}, year = {{2017}}, } @article{3307, author = {{Frick, Bernd and Kaimann, Daniel}}, journal = {{Applied Economics Letters}}, number = {{17}}, pages = {{1237--1240}}, publisher = {{Taylor & Francis}}, title = {{{The impact of customer reviews and advertisement efforts on the performance of experience goods in electronic markets}}}, doi = {{10.1080/13504851.2016.1270399}}, volume = {{24}}, year = {{2017}}, } @misc{3312, author = {{Zarindast, Mana}}, publisher = {{Universität Paderborn}}, title = {{{The role of eWOM in the movie industry: The effect of online user ratings on box office sales }}}, year = {{2017}}, } @inproceedings{3325, author = {{Melnikov, Vitalik and Hüllermeier, Eyke}}, booktitle = {{Proceedings. 27.

As an alternative to the usual cascaded biexciton-exciton emission, direct two-photon emission from the biexciton can be used. With a high-quality optical resonator tuned to half the biexciton energy, a large proportion of the photons can be steered into the two-photon emission channel. In this case the degree of polarization entanglement is inherently insensitive to the exciton fine-structure splitting. In the present work we analyze the biexciton emission with particular emphasis on the influence of coupling of the quantum-dot cavity system to its environment. Especially for a high-quality cavity, the coupling to the surrounding semiconductormaterial can open up additional phonon-assisted decay channels. Our analysis demonstrates that with the cavity tuned to half the biexciton energy, the potentially detrimental influence of the phonons on the polarization entanglement is strongly suppressed—high degrees of entanglement can still be achieved. We further discuss spectral properties and statistics of the emitted twin photons.}}, author = {{Heinze, Dirk and Zrenner, Artur and Schumacher, Stefan}}, issn = {{1098-0121}}, journal = {{Physical Review B}}, number = {{24}}, title = {{{Polarization-entangled twin photons from two-photon quantum-dot emission}}}, doi = {{10.1103/PhysRevB.95.245306}}, year = {{2017}}, } @article{3487, author = {{Hendrik Betzing, Jan and Beverungen, Daniel and Becker, Jörg and Matzner, Martin and Schmitz, Gertrud and Bartelheimer, Christian and Berendes, Carsten Ingo and Braun, Marina and Gadeib, Andera and Hoffen}, Moritz {von and Schallenberg, Christian}}, journal = {{HMD Praxis der Wirtschaftsinformatik}}, number = {{5}}, pages = {{659----671}}, title = {{{Interaktive, digitale Einkaufserlebnisse in Innenstädten}}}, doi = {{10.1365/s40702-017-0343-0}}, year = {{2017}}, } @article{3488, author = {{Beverungen, Daniel and Bräuer, Sebastian and Plenter, Florian and Klör, Benjamin and Monhof, Markus}}, journal = {{Computer Science --- Research and Development}}, number = {{1-2}}, pages = {{195----209}}, title = {{{Ensembles of Context and Form for Repurposing Electric Vehicle Batteries: An Exploratory Study}}}, doi = {{10.1007/s00450-016-0306-7}}, year = {{2017}}, } @article{3490, abstract = {{Digital interactions among businesses and consumers through powerful information systems and omnipresent connected devices establish today’s networked society. In this light, Service Science continues to take root as a research discipline that focuses on the integration of (digital) resources by service providers and service customers for value co-creation in service systems. Rapid advances in information technology allow for designing novel information systems that enable entirely new configurations of service systems. In turn, Service Science also leaves its mark on the design, adoption, and use of information systems and technology. With this special issue, we compile a set of timely papers that investigate selected facets of the complex interplay between information technology, information systems, and Service Science to design innovative IT artifacts for smart service. This editorial opens this special issue by elaborating on our understanding of smart service.
