The Impact of Openness on Value Co-creation in Production Networks

AbstractThe increasing number and economic importance of production networks is one sign of the on-going paradigm shift from industrial production to value co-creation. This transformation can be described by using the notions of a value creation taxonomy, which is introduced in this paper and gives a structured overview of relevant aspects of the underlying conversion from top down to bottom up economics. In order to gain a deeper understanding of this transformation process, the specific design, characteristics and challenges of those networks will be investigated with regard to their time-dependence using a life cycle model.The present study contributes to a fundamental understanding of the importance of openness as a key success factor of value co-creation in production networks. It gives a systematic characterization of what is meant by “openness” concerning the value creation system, the value creation process and the value creation artifact. Furthermore, an adjusted life cycle model is presented, which may support both, assessment and configuration of openness within those networks by deriving adequate and phase-specific measures

Apportioned Commodity Fetishism and the Transformative Power of Game Studies

This chapter explores the ways in which the field of Game Studies helps shape popular understandings of player, play, and game, and specifically how the field alters the conceptual, linguistic, and discursive apparatuses that gamers use to contextualize, describe, and make sense of their experiences. The chapter deploys the concept of apportioned commodity fetishism to analyze the phenomena of discourse as practice, persona, and vagaries of game design, recursion, lexical formation, institutionalization, systems of self-effectiveness, theory as anti-theory, and commodification

Transapical mitral valve implantation for treatment of symptomatic mitral valve disease: a real-world multicentre experience.

AIMS Transcatheter mitral valve implantation (TMVI) is a new treatment option for patients with symptomatic mitral valve (MV) disease. Real-world data have not yet been reported. This study aimed to assess procedural and 30-day outcomes of TMVI in a real-world patient cohort. METHOD AND RESULTS All consecutive patients undergoing implantation of a transapically delivered self-expanding valve at 26 European centres from January 2020 to April 2021 were included in this retrospective observational registry. Among 108 surgical high-risk patients included (43% female, mean age 75 ± 7 years, mean STS-PROM 7.2 ± 5.3%), 25% was treated for an off-label indication (e.g. previous MV intervention or surgery, mitral stenosis, mitral annular calcification). Patients were highly symptomatic (New York Heart Association [NYHA] functional class III/IV in 86%) and mitral regurgitation (MR) was graded 3+/4+ in 95% (38% primary, 37% secondary, and 25% mixed aetiology). Technical success rate was 96%, and MR reduction to ≤1+ was achieved in all patients with successful implantation. There were two procedural deaths and 30-day all-cause mortality was 12%. At early clinical follow-up, MR reduction was sustained and there were significant reductions of pulmonary pressure (systolic pulmonary artery pressure 52 vs. 42 mmHg, p < 0.001), and tricuspid regurgitation severity (p = 0.013). Heart failure symptoms improved significantly (73% in NYHA class I/II, p < 0.001). Procedural success rate according to MVARC criteria was 80% and was not different in patients treated for an off-label indication (74% vs. 81% for off- vs. on-label, p = 0.41). CONCLUSION In a real-world patient population, TMVI has a high technical and procedural success rate with efficient and durable MR reduction and symptomatic improvement

Conradi T, Derwanz H, Muhle F, eds. Strukturentstehung durch Verflechtung. Akteur-Netzwerk-Theorie(n) und Automatismen. Schriftenreihe des Graduiertenkollegs "Automatismen". München: Fink; 2011.Die Akteur-Netzwerk-Theorie stellt mit ihrem Anliegen, die Verflechtungen zwischen Natur, Kultur, Gesellschaft und Technik strikt empirisch zu erforschen, eine Herausforderung für die Sozial- und Kulturwissenschaften dar. Dieser Herausforderung widmet sich der Band aus einer interdisziplinären Perspektive. Ein Hauptinteresse gilt der Frage, wie mit der Akteur-Netzwerk-Theorie die Entstehung ungeplanter Strukturen untersucht werden kann. Nach einem einleitenden Text von John Law wird eine kritische Diskussion über die überraschende Handlungsfähigkeit nicht-menschlicher Akteure, die Verteilung von Macht in Netzwerken sowie mögliche Akzentverschiebungen und theoretische Anschlüsse an die ANT entfaltet. Die Beiträge gehen dabei der Handlungsmächtigkeit von Viren, Problemen des Regierens nach Hurrikan Katrina oder der Frage einer nicht-modernen Geschichte moderner Medien nach
