Einige akademische Arbeiten behaupten, dass Software, die in einem offenen Prozess erstellt wurde, strukturierter ist, als Programme, die im geschlossenen Umfeld entstanden sind. Die Rede ist hier von Open Source und Closed Source. Der Nachweis dieser Annahme wird mit der Technik der so genannten Design Structure Matrix (DSM) erbracht. DSM erlauben die Visualisierung der Struktur einer Software und ermöglichen das Berechnen von Metriken, mit denen dann der Level an Modularität der einzelnen Open Source Software (OSS) verglichen werden kann. Unter zu Hilfename dieser Technik geht die Diplomarbeit der Frage nach, ob ein Zusammenhang zwischen Geschäftsmodell und OSS existiert.
Virtueller Konsum - Warenkörbe, Wägungsschemata und Verbraucherpreisindizes in virtuellen Welten
(2015)
Virtual worlds have been investigated by several academic disciplines for several years, e.g. sociology, psychology, law and education. Since the developers of virtual worlds have implemented aspects like scarcity and needs, even economic research has become interested in these virtual environments. Exploring virtual economies mainly deals with the research of trade regarding the virtual goods used to supply the emerged needs. On the one hand, economics analyzes the meaning of virtual trade according to the overall interpretation of the economical characteristics of virtual worlds. As some virtual worlds allow the change of virtual world money with real money and vice versa, virtual goods are traded by the users for real money, researchers on the other hand, study the impact of the interdependencies between virtual economies and the real world. The presented thesis mainly focuses on the trade within virtual worlds in the context of virtual consumption and the observation of consumer prices. Therefore, the four virtual worlds World of Warcraft, RuneScape, Entropia Universe and Second Life have been selected. There are several components required to calculate consumer price indices. First, a market basket, which contains the relevant consumed goods existing in virtual worlds, must be developed. Second, a weighting scheme has to be established, which shows the dispersion of consumer tendencies. Third, prices of relevant consumer goods have to be taken. Following real world methods, it is the challenge to apply those methods within virtual worlds. Therefore, this dissertation contains three corresponding investigation parts. Within a first analysis, it will be evaluated, in how far virtual worlds can be explored to identify consumable goods. As a next step, the consumption expenditures of the avatars will be examined based on an online survey. At last, prices of consumable goods will be recorded. Finally, it will be possible to calculate consumer price indices. While investigating those components, the thesis focuses not only on the general findings themselves, but also on methodological issues arising, like limited access to relevant data, missing legal legitimation or security concerns of the users. Beside these aspects, the used methods also allow the examination of several other economic aspects like the consumption habits of the avatars. At the end of the thesis, it will be considered to what extent virtual world economic characteristics can be compared with the real world.
Aspects like the important role of weapons or the different usage of food show significant differences to the real world, caused by the business models of virtual worlds.
This master thesis is about the possibilities of supporting local corporate sales with the help of current mobile applications. The internet already has served in order to make the trading market more dynamic. The conditions for long-term local corporate sales have become more challenging. Because of smaller cost structures online-retailer offer prizes on which local point of sales can hardly keep up with. Another point is that more customers decide to order online because the service in e-shops enhanced; therefore, the digital transactions become more attractive for consumers. Today smartphones and tablets have brought the digitalization to a whole new level. With the possibility of Mobile Web the effects that the internet already showed us in the past have been intensified. The question that proposes here is: In which way do the conditions of competitions for local corporate sales change? This paper follows the outline of putting together various mobile services, their functions, and their practical usage, as well as the process of integrating them successfully into marketing. With that one should be able to find out if Mobile Web can be seen as an advantage for local corporates sales.
Unternehmen in Netzwerken
(2007)
The architecture of decentralized digital transaction systems with public transaction history provides no transaction monitoring to prevent unwanted transactions and to identify the transmitter and receiver of those transactions. With the introduction of a public list of unwanted addresses, it is possible to isolate these unwanted addresses by general exclusion and thereby to prevent unwanted transactions, as well as to identify the owners of unwanted addresses. The public list management can be performed by decentralized multiple instances using a trust network, so that the decentralized nature of the systems is maintained.
Social networking platforms as creativity fostering systems: research model and exploratory study
(2008)
Social networking platforms are enabling users to create their own content, share this content with anyone they invite and organize connections with existing or new online contacts. Within these electronic environments users voluntarily add comments on virtual boards, distribute their search results or add information about their expertise areas to their social networking profiles and thereby share it with acquaintances, friends and increasingly even with colleagues in the corporate world. As a result, it is most likely that the underlying knowledge sharing processes result in many new and creative ideas. The objective of our research therefore is to understand if and how social social networking platforms can enforce creativity. In addition, we look at how these processes could be embedded within the organizational structures that influence innovative knowledge sharing behavior. The basis for our research is a framework which focuses on the relations between intrinsic motivation, creativity and social networking platforms. First results of our empirical investigation of a social software platform called "StudiVZ.net" proved that our two propositions are valid.
In dieser Arbeit wird ein Datenmodell für Shared Annotations vorgestellt. Basierend auf einem bereits existierenden Datenmodell für Annotationen, wird dieses erweitert um die Möglichkeit der Modellierung von Shared Annotations. Daraufhin werden Funktionen von Shared Annotations erläutert, die über das neue Annotationsmodell möglich sind.
In the last few years, information technology experienced a great increase. People and Enterprises are able to exchange information through the development of the Web 2.0 to the Social Web. Social Networks like Facebook or Xing, blogs from known and unknown people or the many discussion forums are common platforms where people have the opportunity to share and exchange information. Enterprises and people have to accept this fact and development. The reputation is also influenced by the overabundance of information. The result of this development is the digital reputation, which extend the entire reputation. Everyone who is looking for an order or a job can assume that his orrnher name will be "googled", whether he or she is a part of an internet branch or not. Every information is available through search engines. Just a quick look at the Facebook or Xing profile is needed to get a brief impression of someone. The communications expert Klaus Eck said that someone who takes the internet seriously will get a benefit for the development of his digital reputation. This research work will show you through a self made questionnaire what is seen as positive and negative influences on the reputation in Social Networks and how the digital reputation impacts the entire reputation.
Prävention von Korruption
(2006)
The known methods of the prevention of corruption are set into context of comparable ways to obviate accidences during working processes, environmental pollution by organisations and the options to ensure quality for manufactured goods. The aim was to find out if and in which degree the different methods of prevention in the area of corruption and the mentioned aspects of the TQM support each other.
