The problematization of waste surplus informed numerous decisions on local, national and international levels. However, the waste pollution problem is far from being solved. This paper attempts to explore an alternative way of organizing waste using the Actor-Network Theory, which argues for equality between humans and nonhumans. We are taking this approach and recognising the role of waste as an essential actor in the decision-making process around waste management. Based on a case study of a second-hand shop, so-called Överskottet, where wasted materials are being transported and processed by people with special needs. We showcased how these alternative ways can be implemented. This shop is part of a collaboration between the Waste Management Department and the Social Services Department of Gotland’s municipality, namely, Region Gotland. This collaboration is a perfect example of the connection between the material and the social. In our study, we are analysing connections between waste and humans on different levels (i.e. municipality departments, humans and wasted materials) and show how these connections create a collaborative network that has both social and environmental impact. We account for factors that strengthen and factors that weaken, thus destabilising the collaboration network. Finally, we highlighted how these collaborations require adapting the existing policies surrounding waste management.

Educational institutions are known to be at the heart of complex computing systems in any region in which they exist, especially in Africa. The existence of high end computing power, often connected to the Internet and to research network grids, makes educational institutions soft targets for attackers. Attackers of such networks are normally either looking to exploit the large computing resources available for use in secondary attacks or to steal Intellectual Property (IP) from the research networks to which the institutions belong. Universities also store a lot of information about their current students and staff population as well as alumni ranging from personal to financial information. Unauthorized access to such information violates statutory requirement of the law and could grossly tarnish the institutions name not to mention cost the institution a lot of money during post-incident activities. The purpose of this study was to investigate the information security practices that have been put in place by Research and Education Network of Uganda (RENU) member institutions to safeguard institutional data and systems from both internal and external security threats. The study was conducted on six member institutions in three phases, between the months of May and July 2011 in Uganda. Phase One involved the use of a customised quantitative questionnaire tool. The tool - originally developed by information security governance task-force of EDUCAUSE - was customised for use in Uganda. Phase Two involved the use of a qualitative interview guide in a sessions between the investigator and respondents. Results show that institutions rely heavily on Information and Communication Technology (ICT) systems and services and that all institutions had already acquired more than three information systems and had acquired and implemented some of the cutting edge equipment and systems in their data centres. Further results show that institutions have established ICT departments although staff have not been trained in information security. All institutions interviewed have ICT policies although only a few have carried out policy sensitization and awareness campaigns for their staff and students. / TeX

The diploma thesis deals with the design of information security management in the industrial environment. In the first part of thesis is mentioned the theoretical background from the area of information security. The analysis of the default status is followed, and the risk analysis is also performed. Further, the thesis deals with the design of the industrial network infrastructure and its management.

This dissertation focuses on selected aspects of network congestion arising in liberalized electricity markets and their management methods with a special weight placed on the integration of increased renewable generation in Europe and Germany. In a first step, the theoretical concepts of congestion management are introduced complemented by a review of current management regimes in selected countries. In the second step, the European approach of managing congestion on international as well as national transmission links is analyzed and the benefits of an integrated congestion management regime are quantified. It is concluded that benefits can be achieved by a closer cooperation of national transmission system operators (TSOs). Thirdly, the German congestion management regime is investigated and the impact of higher renewable generation up to 2020 on congestion management cost is determined. It is shown that a homogeneous and jointly development of generation and transmission infrastructure is a prerequisite for the application of congestion alleviation methods and once they diverge congestion management cost tend to increase substantially. Lastly, the impact of intermittent and uncertain wind generation on electricity markets is analyzed. A stochastic electricity market model is described, which replicates the daily subsequent clearing of reserve, dayahead, and intraday market typical for European countries, and numerical results are presented.

Diploma thesis deals with analyzing the possibility of using artificial intelligence, specifically artificial neural networks and fuzzy logic, on the capital markets as a tool to support decision making in business. The Matlab software is used for this purpose. The work is divided into three parts. The first part deals with theoretical knowledge, brief description of the current situationin is covered in a second part and the theoretical solutions are applied to the system in the third section.

Community members benefit from the opportunities and services that are provided by park and recreation departments. As technology has continued to improve, it has begun to influence some of the services and programs offered by park and recreation departments. This study presents information regarding World Wide Web use in parks and recreation departments in 1998. The study surveyed those park and recreation departments who were members of the National Recreation and Parks Association's Great Lakes Region in 1998. A total of 419 departments were included in the study. These 419 departments were grouped into three population categories (Under 15,000; 15,000-49,999; 50,000 and above). A survey return rate of 58% was achieved. Survey respondents were asked to list current and future uses of the World Wide Web in their departments by program and by activity. Respondents were also asked to identify why they were or were not using the web. The study also examined if there were differences between agency size and World Wide Web use, agency size and the number of computers used, and agency size and the number of computer specialists employed. Recreation professionals can use this study to identify whether their department would benefit from World Wide Web use. The information can assist in identifying strengths and weaknesses of the web in the recreation profession and in departments similar to their own. / School of Physical Education

Supply Chain Event Management (SCEM) bezeichnet eine Teildisziplin des Supply Chain Management und ist für Unternehmen ein Ansatzpunkt, durch frühzeitige Reaktion auf kritische Ausnahmeereignisse in der Wertschöpfungskette Logistikleistung und -kosten zu optimieren. Durch Rahmenbedingungen wie bspw. globale Logistikstrukturen, eine hohe Artikelvielfalt und volatile Geschäftsbeziehungen zählt die Modeindustrie zu den Branchen, die für kritische Störereignisse besonders anfällig ist. In diesem Sinne untersucht die vorliegende Dissertation nach einer Beleuchtung der wesentlichen Grundlagen zunächst, inwiefern es in der Modeindustrie tatsächlich einen Bedarf an SCEM-Systemen gibt. Anknüpfend daran zeigt sie nach einer Darstellung bisheriger SCEM-Architekturkonzepte Gestaltungsmöglichkeiten für eine Systemarchitektur auf, die auf den Designprinzipien der Serviceorientierung beruht. In diesem Rahmen erfolgt u. a. auch die Identifikation SCEM-relevanter Business Services. Die Vorzüge einer serviceorientierten Gestaltung werden detailliert anhand der EPCIS (EPC Information Services)-Spezifikation illustriert. Abgerundet wird die Arbeit durch eine Betrachtung der Nutzenpotenziale von SCEM-Systemen. Nach einer Darstellung von Ansätzen, welche zur Nutzenbestimmung infrage kommen, wird der Nutzen anhand eines Praxisbeispiels aufgezeigt und fließt zusammen mit den Ergebnissen einer Literaturrecherche in eine Konsolidierung von SCEM-Nutzeffekten. Hierbei wird auch beleuchtet, welche zusätzlichen Vorteile sich für Unternehmen durch eine serviceorientierte Architekturgestaltung bieten. In der Schlussbetrachtung werden die wesentlichen Erkenntnisse der Arbeit zusammengefasst und in einem Ausblick sowohl beleuchtet, welche Relevanz die Ergebnisse der Arbeit für die Bewältigung künftiger Herausforderungen innehaben als auch welche Anknüpfungspunkte sich für anschließende Forschungsarbeiten ergeben.
