In the period between 1985 and 1994 ethnic conflicts had a part for more than 50% of the total number of conflicts. Oftentimes, conflicts may arise between different ethnic groups or between one ethnic group and the state. The reasons for this are varied in ranging from social deprivation to the threat of collective identity. An essential key role is played by the political elite, which takes advantage of political and economic crises in order to mobilize certain ethnic groups.
This thesis attempts to investigate such ethnic conflicts on the case of former Yugoslavia, focusing in particular on the role of the political elite. For this purpose, the approach of an agent-based simulation is been followed. The agent-based model, which is carried by ArcGIS, EmIL and Repast allows a thorough investigation of such conflicts. The main feature lies in the ability of agents to be able to develop a normative behavior, so that compex social behaviors can be simulated.
Activity recognition with smartphones is possible by using its internal sensors without using any external sensor. First of all, previous works and their techniques will be regarded and from these works an own implementation for the activity recognition will be derived. Most of the previous works only use the accelerometer for the activity recognition task. For this reason, this bachelor thesis analyzes the benefit of further sensors, such as the magnetic field, the linear acceleration or the gyroscope. The activity recognition is performed by classification algorithms. Decision Tree, Naive Bayes and Support Vector machines will be used. Sensor data of subjects will be collected and saved by using an own developed application. This data is needed as training data for the classification algorithms.
The result is a model which represents the structure of the data. To validate the model, a test dataset will be used which is different from the training dataset. The results confirm previous works which indicated that the activity recognition task is possible by only using the accelerometer. Orientation, gyroscope and linear acceleration cannot be used for all problems of the activity recognition. Apart from that, the Decision Tree seems to be the best classification algorithm if the model has no training data of the current user.
This thesis aims to clarify the question of how stakeholders can participate in a project. We discuss methods on how to select the relevant stakeholders from the whole set of the stakeholders and how to involve these stakeholders in the participatory process. The participation process does not only classical methods of participation such as workshops, especially before modern Web 2.0 techniques.
With the reaccreditation of the degree programs in the department of computer science at the University of Koblenz-Landau new trendsetting degree programs will be offered. For further planning and design of the individual degree programs the opinion of the students is a considerable indicator. Information about the new degree programs aren"t available during the accreditation process. Students have an interest in knowing about the new degree programs and the new examination regulation and therefore being part in the decision process would be desirable. The concept of e-participation is an opportunity to satisfy this need. It offers the possibility to discuss topics of the accreditation and to bring in own ideas and opinions into the decision process. This bachelor thesis describes an e-participation project at the University of Koblenz-Landau about the accreditation of the degree programs of the faculty of computer science. By using the reference framework of Scherer and Wimmer (2011) the project will be carried out. Furthermore the accreditation process will be modeled to get a better understanding of the whole process and to identify the possibilities for e-participation project integration. The results of this project are going to be covered by an online survey about the e-participation platform. Using the results of the survey and the experiences gained after the project recommendations are given for further e-participation projects. Moreover the reference framework of Scherer and Wimmer (2011) will be analyzed critically.
The measurement of the benefits of collaborative technologies is a challenge caused by sociological influences on these systems. In this work, the introduction of a collaborative system into an existing IT environment is examined, so that a value can be identified for the company. The analysis of frameworks has shown that the benefits can be reaped through better management and organization of in-company resources and optimization of the underlying process.
The World Wide Web (WWW) has become a very important communication channel. Its usage has steadily grown within the past. Interest by website owners in identifying user behaviour has been around since Tim Berners-Lee developed the first web browser in 1990. But as the influence of the online channel today eclipses all other media the interest in monitoring website usage and user activities has intensified as well. Gathering and analysing data about the usage of websites can help to understand customer behaviour, improve services and potentially increase profit.
It is further essential for ensuring effective website design and management, efficient mass customization and effective marketing. Web Analytics (WA) is the area addressing these considerations. However, changing technologies and evolving Web Analytic methods and processes present a challenge to organisations starting with Web Analytic programmes. Because of lacking resources in different areas and other types of websites especially small and medium-sized enterprises (SME) as well as non-profit organisations struggle to operate WA in an effective manner.
This research project aims to identify the existing gap between theory, tool possibilities and business needs for undertaking Web Analytic programmes. Therefore the topic was looked at from three different ways: the academic literature, Web Analytic tools and an interpretative case study. The researcher utilized an action research approach to investigate Web Analytics presenting an holistic overview and to identify the gaps that exists. The outcome of this research project is an overall framework, which provides guidance for SMEs who operate information websites on how to proceed in a Web Analytic programme.
In this bachelor thesis a tangible augmented reality game was developed, which should have a additional benefit compared to conventional computer or augmented reality games. The main part of the thesis explains the game concept, the development and the evaluation of the game. In the evaluation the flow-experience, as measurement for the games" amusement, was analysed with a user test and the developed game was compared with other smartphone games. Also augmented reality, tangible user interface and tangible augmented reality was introduced and the advantages and disadvantages was explained. The history of augmented reality was introduced too.
