Analyse der Tätigkeiten kardiovaskulärer Gewebebanken in Deutschland in den Jahren 2007 bis 2010

__Background:__ Especially in complicated aortic valve endocarditis, infections of the aorta by mycotic aortic aneurysms and prosthetic infections, or as part of the Ross procedure, the use of allogeneic heart valve transplants remains important. The production of such allografts in Germany is the task of cardiovascular tissue banks (CVTB). __Materials and methods:__ During an analysis of the years 2007-2010, basic data on donor numbers, production, and distribution as well as the technical conditions of not only the four participating CVTB (Bad Oeynhausen, Berlin, Kiel, Munich) but also data from the CVTB Rotterdam as an external reference were recorded. __Results:__ The German CVTB delivered an average of 44 aortic and 95 pulmonary allografts per year to clinical users. By incorporating the annually imported valve allografts, the demand in Germany approximately averages 220 heart valve allografts per year. The heart tissue was harvested from approximately 100 multiorgan donors, 45 cardiovascular deaths, and 80 domino donors annually. __Discussion:__ The participating cardiovascular tissue banks have comparable technical and administrative requirements and are able to produce tissue preparations according to the rules of Good Professional Practice in accordance with § 3 (3) AMWHV to assess their quality, whereby harmonization of microbiological monitoring and antibiotic treatment is still necessary

Goal setting for persuasive information systems: Five reference checklists

The concept of goals is prominent in information systems and also artificial intelligence literature such as goal-oriented requirements engineering and self-adaptive systems. Digital motivation systems, e.g. gamification and persuasive technology, utilise the concept of behavioural goals which require a different mind-set on how to elicit and set them up, how to monitor deviation from such goals and how to ensure their completion. Behavioural goals are characterised by a range of factors which are not the main focus in classic information systems and AI literature such as self-efficacy, perceived usefulness. To engineer software supporting goal setting, a concretised taxonomy of goals would help a better-managed analysis and design process. In this paper, we provide a detailed classification of behavioural goals and their associated properties and elements (types, sources, monitoring, feedback, deviation and countermeasures). As a method, we review the literature on goal setting theory and its application in different disciplines. We subsequently develop five reference checklists which would act as a reference point for researchers and practitioners in persuasive and motivational systems

What is eSports and why do people watch it?

PurposeThe purpose of this paper is to investigate why do people spectate eSports on the internet. The authors define eSports (electronic sports) as “a form of sports where the primary aspects of the sport are facilitated by electronic systems; the input of players and teams as well as the output of the eSports system are mediated by human-computer interfaces.” In more practical terms, eSports refer to competitive video gaming (broadcasted on the internet).Design/methodology/approachThe study employs the motivations scale for sports consumption which is one of the most widely applied measurement instruments for sports consumption in general. The questionnaire was designed and pre-tested before distributing to target respondents (n=888). The reliability and validity of the instrument both met the commonly accepted guidelines. The model was assessed first by examining its measurement model and then the structural model.FindingsThe results indicate that escapism, acquiring knowledge about the games being played, novelty and eSports athlete aggressiveness were found to positively predict eSport spectating frequency.Originality/valueDuring recent years, eSports (electronic sports) and video game streaming have become rapidly growing forms of new media in the internet driven by the growing provenance of (online) games and online broadcasting technologies. Today, hundreds of millions of people spectate eSports. The present investigation presents a large study on gratification-related determinants of why people spectate eSports on the internet. Moreover, the study proposes a definition for eSports and further discusses how eSports can be seen as a form of sports.</jats:sec
