Das CO2-Grenzausgleichssystem der EU kann die Verlagerung der Produktion bzw. von Emissionen in Drittländer nur zum Teil verhindern. Es wird sehr hohe Kosten verursachen, nicht zu einer kosteneffizienten Emissionsreduktion beitragen und kaum Anreize für Drittländer schaffen, ihre Emissionen zu reduzieren. Das System ist nicht WTO-konform und wird deshalb Anlass zu handelspolitischen Streitigkeiten und Konflikten geben, unter denen vor allem Deutschland mit seinen hohen Exportüberschüssen zu leiden haben wird. Es spricht vieles dafür, das vorgeschlagene System nicht zu realisieren und die Wettbewerbsnachteile europäischer Unternehmen weiter durch die teilweise kostenlose Zuteilung von ETS-Zertifikaten auszugleichen.

In this paper, we argue that the traditional view of a smart service as something that is tied to a physical product is too limited. After reviewing key aspects of smart services in the literature, we propose a broader definition that retains key characteristics while opening up the concept for a broader, intangible context, such as the professional service industry. In order to make the term even more specific, a checklist is developed that classifies services as (not) smart, based on a range of different criteria. These criteria are generated from a structured literature review and supplemental interviews with subject experts. Finally, the usefulness of the new definition and the associated checklist is demonstrated with an example from automated auditing.

Background: Loneliness and social isolation in older age are considered major public health concerns and research on technology-based solutions is growing rapidly. This scoping review of reviews aims to summarize the communication technologies (CTs) (review question RQ1), theoretical frameworks (RQ2), study designs (RQ3), and positive effects of technology use (RQ4) present in the research field. Methods: A comprehensive multi-disciplinary, multi-database literature search was conducted. Identified reviews were analyzed according to the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) framework. A total of N = 28 research reviews that cover 248 primary studies spanning 50 years were included. Results: The majority of the included reviews addressed general internet and computer use (82% each) (RQ1). Of the 28 reviews, only one (4%) worked with a theoretical framework (RQ2) and 26 (93%) covered primary studies with quantitative-experimental designs (RQ3). The positive effects of technology use were shown in 55% of the outcome measures for loneliness and 44% of the outcome measures for social isolation (RQ4). Conclusion: While research reviews show that CTs can reduce loneliness and social isolation in older people, causal evidence is limited and insights on innovative technologies such as augmented reality systems are scarce.

Working-from-home arrangements have become increasingly important for firms’ work organization. In this context, the COVID-19 pandemic has led to teams that previously did not work virtually being forced to interact and communicate virtually. In this study, we analyze changes in intra-team communication of four teams in a German medium-sized enterprise. Quantitative network analyses of email communication and qualitative analyses of interviews before and during the COVID-19 lockdown in spring 2020 show that flat hierarchies and self-managing processes helped team members to mitigate negative effects due to spatial and temporal dispersion in forced working-from-home arrangements. Moreover, analysis of the teams’ communication networks shows that forced remote work can trigger faultlines to become salient but that team cohesion, identification with the team, and individuals taking on broker roles prevent negative effects of faultlines on team performance. In discussing these findings, our study contributes to the research on coordination and communication in virtual teams by analyzing contextual, organizational, team-related as well as individual factors that explain how and why teams differ in successfully implementing working-from-home arrangements.
