As from the beginning of the late 70's an impressive number of innovative electronic payment systems have been developed and tested commercially. However, the resulting variety and complexity of the systems have turned out to be one of the obstacles for the broad acceptance of electronic payment. In this paper we propose a process and service oriented framework, which offers a structural and conceptual orientation in the field of electronic payment. It renders possible an integral view on electronic payment that goes beyond the frame of an individual system. To do this, we have generalized the systems-oriented approaches to a phase-oriented payment model. Using this model, requirements and supporting services for electronic payment can be sorted systematically and described from both the customers' and the merchants' viewpoint. Providing integrated payment processes and services is proving to be a difficult task. With this paper we would like to outline the necessity for a Payment Service Provider to act as a mediator for suppliers and users of electronic payment systems.
Currently, there is a global problem of an increasing need of energy. There will be less fossil fuel, which will be more expensive in the future. The regenerative energies are getting more and more important. The subject deals with the problem of economical feasibility of geothermal energy systems. Its goal is to analyze nessesary conditions and aspects for realizing geothermal energy systems in comparison to and competition with traditional energy sources. The geothermal energy recovery is economically advantageous if the investment costs, esp. the drilling costs, could be reduced significantly. It only seems possible to open up a big opportunity for realizing geothermal energy systems by using a rock melt drilling technology, to reduce the investment costs significantly.
A reference model is always developed in order to support a specific purpose. The development environment is setting the broader context. Limitations are not only set by size and experience of the modeler team or by budget and time constraints. The intended usage scenario also defines the fundamental contour of a reference model. During the practical work with reference models, a range of key issues has come up to increase the suitability of reference models for daily use. As the result of many projects, the authors have summarized the key issues and formulated critical success factors for reference modeling projects.

IT performance measurement is often associated by chief executive officers with IT cost cutting although IT protects business processes from increasing IT costs. IT cost cutting only endangers the company’s efficiency. This opinion discriminates those who do IT performance measurement in companies as a bean-counter. The present paper describes an integrated reference model for IT performance measurement based on a life cycle model and a performance oriented framework. The presented model was created from a practical point of view. It is designed lank compared with other known concepts and is very appropriate for small and medium enterprises (SME).
Mergers and acquisitions take place all over the world and in many industries, typically motivated by corporate politics. While IT management is often not involved in the decision-making, it has to solve a wide range of problems in the post-merger phase. Indeed, merging two or more companies implies not only merging their core businesses, but also creating a new and efficiently integrated IT organisation from the individual ones, since persistence of the current IT organisations usually does not make sense. In addition, corporate management frequently imposes constraints, e.g., cost reductions, on the IT infrastructure. The principal critical success factor when merging IT organisations is the uninterrupted operation of the IT business, because a service gap is neither acceptable for in-house functional departments nor for external customers. Therefore, the IT rebuilding phase has to focus on IT services that facilitate the processes of functional departments, support processes, and processes of customers and suppliers, so that any transformation work is transparent to internal and external customers. In this article we describe a real-world but anonymous case study. Our goals are to highlight the points important for merging IT organisations, and to help decision-makers, particularly in the areas of IT organisation and IT personnel. We focus on the arising organisational and non-technical issues from a management perspective, i.e., the CIO's view, and provide checklists intended to help IT managers to address the most pressing issues. To assist CIOs surviving in the post merger phase, we give check lists for merging IT organisations, check lists for merging IT human resources, check lists for IT budgets and reporting, and assess activities in a merger scenario. IT hardware, software and IT infrastructure as well as running IT projects are not considered in this paper.
The short survey „Green IT 2009“ got a very pleasant feedback. The authors received 132 useful answers within only two weeks of survey (15th January until 31st January 2009). The electronic forms were sent to 1.000 companies in Germany and some neighbouring countries. The results show very clearly that the companies are already acting. Green IT has found its way into the companies in different ways and activities. But Green IT is known as a technical topic of IT management or building services engineering. The investments are made mostly in technical activities (energy saving hardware, virtualisation, cooling and more). From a business view the sourcing departments have to change their strategies and processes. The type and amount of IT investment decisions are not concerned by Green IT activities. The main targets of the companies are saving energy and costs followed by advancements in marketing and innovation.
In this paper, we present the results of a controlled human experiment where students in a business process modelling course had to model a business process from a case study as part of their coursework. One group could take advantage of the continuous validation feature that is implemented in the bflow modelling tool, i.e. they were provided with alerts about modelling errors. A control group had to create a model for the same case study without using continuous validation. The results of the experiment indicate that the presence of continuous validation indeed has had a positive effect on the number of syntactic errors in business process models.
Green IT (Green IS, Green ICT) is a concept of saving energy consumption to reduce IT costs. A current survey shows that only few companies in German speaking countries consider this aspect in their daily business. This is important facing the current situation of attempts of cost saving during the current economic crisis worldwide. This paper introduces into Green IT and presents an IT management and controlling concept. Then the main results of a currently presented survey are used to modify the concept. Finally an agenda for future research is given.

This article concerns the design and development of Information- and Communication Technology, in particular computer systems in regard to the demographic transition which will influence user capabilities. It is questionable if current applied computer systems are able to meet the requirements of altered user groups with diversified capabilities. Such an enquiry is necessary based on actual forecasts leading to the assumption that the average age of employees in enterprises will increase significantly within the next 50-60 years, while the percentage of computer aided business tasks, operated by human individuals, rises from year to year. This progress will precipitate specific consequences for enterprises regarding the design and application of computer systems. If computer systems are not adapted to altered user requirements, efficient and productive utilisation could be negatively influenced. These consequences constitute the motivation to extend traditional design methodologies and thereby ensure the application of computer systems that are usable, independent of user capabilities.
The Federal Ministry of Labour and Social Affairs (Bundesministerium für Arbeit und Soziales, BMA) is supporting 73 projects in Germany using European Union (EU) funds in the amount of € 26 million. By providing the subsidies, the European Commission and the German Federal Government are hoping to implement Corporate Social Responsibility (CSR) among German small and medium-sized businesses (SMBs). The project run by Bonn-Rhein-Sieg University is one of these CSR projects. It is aimed at providing comprehensive information on CSR to the businesses in question and at emphasizing their responsibility along the supply chain.
Although most individuals who gamble do so without any adverse consequences, some individuals develop a recurrent, maladaptive pattern of gambling behaviour, often called pathological gambling or gambling disorder, that is associated with financial losses, disruption of family and interpersonal relationships, and co-occurring psychiatric disorders. Identifying whether different types of gambling modalities vary in their ability to lead to maladaptive patterns of gambling behaviour is essential to develop public policies that seek to balance access to gambling opportunities with minimizing risk for the potential adverse consequences of gambling behaviour. Until recently, assessing the risk potential of different types of gambling products was nearly impossible. ASTERIG, initially developed in Germany in 2006-2010, is an assessment tool to measure and to evaluate the risk potential of any gambling product based on scores on ten dimensions. In doing so, it also allows a comparison to be drawn between the addictive potential of different gambling products. Furthermore, the tool highlights where the specific risk potential of each specific gambling product lies. This makes it a valuable tool at the legislative, case law, and administrative levels as it allows the risk potential of individual gambling products to be identified and to be compared globally and across 10 different dimensions of risk potential. We note that specific gambling products should always be evaluated rather than product groups (lotteries, slot machines) or providers, as there may be variations among those product groups that impact their risk potential. For example, slot machines may vary on the amount of jackpot, which may influence their risk potential.
In discussions of gambling addiction to specific games, the market size and the proceeds generated by the game are usually disregarded. Inclusion of these parameters results in a relativization of the picture of gambling addiction. A fundamental principle for such an analysis is the separation between absolute numbers and ratios, which is a common procedure in economic contexts.
Within an elementary decision of March 28th, 2006 the German Federal Constitutional Court implemented the following: “According to the status quo of research it is certain, that gambling and bets can result in morbid addictive behaviour. ... However different gambling products exhibit different addictive potentials.” Up to now a specific identification of the addictive potential of a concrete gambling product was nearly impossible. This being said, the Wissenschaftliches Forum Glücksspiel (Gambling Scientific Forum) developed a globally applicable assessment tool to measure and evaluate the risk potential of gambling products.

This paper gives an overview of the development of Fair Trade in six European countries: Austria, France, Germany, the Netherlands, Switzerland and the United Kingdom. After the description of the food retail industry and its market structures in these countries, the main European Fair Trade organizations are analyzed regarding their role within the Fair Trade system. The following part deals with the development of Fair Trade sales in general and with respect to the products coffee, tea, bananas, fruit juice and sugar. An overview of the main activities of national Fair Trade organizations, e.g. public relation activities, completes the analysis. This study shows the enormous upswing of Fair Trade during the last decade and the reasons for this development. Nevertheless, it comes to the conclusion that Fair Trade is still far away from being an essential part of the food retail industry in Europe.
In general, mathematics plays a central role in our lives because today mathematics regulates our everyday life with techniques, technologies and procedures, for example coding techniques for credit cards or the drafting of curves and surfaces for construction procedures [5]. Obviously, mathematics continues to be an important element of engineering education and it still represents a major obstacle for the students. Lacking the knowledge of several topics, changing learning behavior and inadequate overall conditions at universities for the repetition of school mathematics were mentioned to be causes for the constantly increasing gap between the initial level of mathematics at university and the prior knowledge of the first semester students [2].
