Computervermittelte Kommunikation. - In: Grundlagen der Informationswissenschaft, (2023), S. 511-523

Der vorliegende Beitrag erklärt, wie computervermittelte Kommunikation definiert ist (Abschnitt 2) und wo sie eingesetzt wird (Abschnitt 3). Anschließend wird der aktuelleForschungsstand umrissen (Abschnitt 4). Der Schwerpunkt des Beitrags liegt auf der Darstellung zentraler Theorien der computervermittelten Kommunikation (Abschnitt 5).

Digital media in intergenerational communication: status quo and future scenarios for the grandparent-grandchild relationship. - In: Universal access in the information society, ISSN 1615-5297, Bd. 0 (2022), 0, insges. 16 S.

Communication technologies play an important role in maintaining the grandparent-grandchild (GP-GC) relationship. Based on Media Richness Theory, this study investigates the frequency of use (RQ1) and perceived quality (RQ2) of established media as well as the potential use of selected innovative media (RQ3) in GP-GC relationships with a particular focus on digital media. A cross-sectional online survey and vignette experiment were conducted in February 2021 among N = 286 university students in Germany (mean age 23 years, 57% female) who reported on the direct and mediated communication with their grandparents. In addition to face-to-face interactions, non-digital and digital established media (such as telephone, texting, video conferencing) and innovative digital media, namely augmented reality (AR)-based and social robot-based communication technologies, were covered. Face-to-face and phone communication occurred most frequently in GP-GC relationships: 85% of participants reported them taking place at least a few times per year (RQ1). Non-digital established media were associated with higher perceived communication quality than digital established media (RQ2). Innovative digital media received less favorable quality evaluations than established media. Participants expressed doubts regarding the technology competence of their grandparents, but still met innovative media with high expectations regarding improved communication quality (RQ3). Richer media, such as video conferencing or AR, do not automatically lead to better perceived communication quality, while leaner media, such as letters or text messages, can provide rich communication experiences. More research is needed to fully understand and systematically improve the utility, usability, and joy of use of different digital communication technologies employed in GP-GC relationships.

Evaluationsforschung. - In: Handbuch Methoden der empirischen Sozialforschung, (2022), S. 195-211

Mit „Evaluationsforschung“, „wissenschaftlicher Evaluation“ oder kurz „Evaluation“ ist die Bewertung eines Gegenstandes mit Hilfe sozialwissenschaftlicher Methoden durch Evaluationsfachleute gemeint (Widmer/De Rocchi 2012: 11). Die Evaluationsforschung ist ein boomendes interdisziplinäres Forschungsfeld, in dem sowohl qualitative als auch quantitative Methoden der empirischen Sozialforschung zum Einsatz kommen (Döring 2022). In zahlreichen Bereichen des öffentlichen Lebens werden Evaluationsmaßnahmen inzwischen rechtlich vorgeschrieben.

Sexuelle Bildungsangebote in sozialen Medien. - In: Mediendiskurs, ISSN 2751-0379, 26. Jg., Heft 4 (2022) = Ausgabe 102, Seite 44-49

Gelingende Sexualität ist keine Selbstverständlichkeit. Wissen und Handlungskompetenzen sind gefragt, um die eigenen sexuellen Bedürfnisse und Grenzen zu erkennen, ein individuell passendes Sexualleben zu gestalten, mit unvermeidbaren sexuellen Problemen und Konflikten fertigzuwerden und an sexueller Kultur und Sexualpolitik kundig zu partizipieren. Sexuelle Bildungsangebote wollen hierbei unterstützen. In sozialen Medien findet man sie in großer Menge und Vielfalt, allerdings auch in sehr heterogener Qualität.

Interpretability of knowledge graph-based explainable process analysis. - In: IEEE Xplore digital library, ISSN 2473-2001, (2022), S. 9-17

The last decade produced rapid developments and powerful new technologies that are creating a huge upsurge in artificial intelligence research. However, for critical operational decisions (e.g., consulting services), the need for explanations and interpretable results are becoming a necessity. The integration of knowledge graphs that provide relevant background knowledge in machine-readable form, and machine learning methods represents a new form of hybrid intelligent systems that benefit from each other's strengths. Our research aims at an explainable system with a specific knowledge graph architecture that can generate human-understandable results even when no suitable domain experts are available. Against this background, the interpretability of a knowledge graph-based explainable artificial intelligence approach for business process analysis is focused. We design a framework of interpretation, and show how interpretable models are generated. Result paths on weaknesses and improvement measures related to a business process are used to produce stochastic decision trees, which improve the interpretability of results. This can lead to interesting consulting self-services for clients or be applied as a device for accelerating classical consulting projects.

Are important phenomena of joint production still being neglected by economic theory? : a review of recent literature. - In: Journal of business economics, ISSN 1861-8928, (2022), insges. 39 S.

Joint production is a term with a long history in economics, encompassing a variety of ubiquitous production types that usually generate both main products as well as desirable and undesirable byproducts. However, studies in economic history show that important phenomena subsumed under this term were largely ignored by the theories of general economics and of business economics in the twentieth century. Our systematic, narrative literature review based on the Web of Science analyses the extent to which this and other terms corresponding to such phenomena have been taken up by researchers since then. Whereas the number of papers on undesirable outputs has soared, especially in the past decade, the economic literature regarding joint production and harmless byproducts is much smaller and hardly growing. This is in stark contrast to their relevance in practice, recorded in the non-economic literature. Harmful byproducts result from coupled production, as a rule. However, this important manifestation of joint production is usually not distinguished from other specific types. In German-language literature, coupled production is defined as a kind of (truly) joint production in which an intended product cannot be manufactured without an additional type of output under consideration. Our review reveals a lack of clarity, precision, and consistency in the use of established terms and concepts in English-language literature, that may lead to insufficient external validity of widely accepted models. Moreover, one gets the impression that academic disciplines concerned with business or general economics focus too much on problems that are currently of economic interest, while neglecting other issues that may be marginal today but are likely to be of critical importance in the near future.
