Auf eine bestehende Erhebung der Gesellschaft für Qualität in der Außerklinischen Geburtshilfe QUAG e.V. wurden moderne statistische Verfahren, insbesondere Faktorenanalyse und Mann-Whitney-U-Test angewendet. Es wurden hierzu die von den Hebammen ausgefüllten Perinatalbögen von 17269 Erstgebärenden aus dem Zeitraum 1999 bis 2004 ausgewertet. Der Mann-Whitney-U-Test wurde für die metrischen Variablen "Alter bei Geburt" und Hebammen-Erstkontakt angewendet. Unter anderem konnte gezeigt werden, dass Frauen mit besonderen sozialen Belastungen erst spät den Kontakt zur Hebamme suchen. Die Faktorenanalyse ergab sehr gut bekannte, aber auch neue Zusammenhänge, was auf die Stärke dieses Verfahrens schließen lässt. Eine kurze geburtshilfliche und/oder medizinische Erklärung wurde, sofern möglich, erstellt und recherchiert. Es ist jedoch weitere Erforschung und medizinische Beurteilung der Einzelergebnisse notwendig.
Abstract It is not easy to compare one statistic with another, and it is even more difficult if the analysis is based on two surveys that do not share the same issue, have different survey methods, and especially if the sample size of the surveys differ greatly. This paper will use a comparison of official and unofficial statistics, the micro-census and the German Socio-Economic Panel Study (SOEP) to confirm this point. An auxiliary structure for study of fertility behavior of women in Germany is conducted first with the micro-census and then with SOEP data. By that the transferability of a study model of the micro-census to the SOEP is examined. The SOEP provides the possibility to check the validity of the auxiliary structure which gives just an estimation of the current situation regarding the childlessness in Germany. The study model will be run for a second time with the SOEP data, however, this time not with the estimated number of mothers, but with the number actually recorded by the SOEP. Thus the quality of the estimation results can be checked.
In the last years the e-government concentrated on the administrative aspects of administrative modernisation. In the next step the e-discourses will gain in importance as an instrument of the public-friendliness and means of the e-democracy/e-participation. With growing acceptance of such e-discourses, these will fastly reach a complexity, which could not be mastered no more by the participants. Many impressions, which could be won from presence discussions, will be lacking now. Therefore the exposed thesis has the objective of the conception and the prototypical implementation of an instrument (discourse meter), by which the participants, in particular the moderators of the e-discourse, are capable to overlook the e-discourse at any time and by means of it, attain their discourse awareness. Discourse awareness of the present informs about the current action in the e-discourse and discourse awareness of the past about the past action, by which any trends become visible. The focus of the discourse awareness is located in the quantitative view of the action in the e-discourse. From the model of e-discourse, which is developed in this thesis, the questions of discourse awareness are resulting, whose concretion is the basis for the implementation of the discourse meter. The discourse sensors attached to the model of the e-discourse are recording the actions of the e-discourse, showing events of discourse, which are represented by the discourse meter in various forms of visualizations. The concept of discourse meter offers the possibility of discourse awareness relating to the present as monitoring and the discourse awareness relating to the past as query (quantitative analysis) to the moderators of the e-discourse.
The internet is becoming more and more important in daily life. Fundamental changes can be observed in the private sector as well as in the public sector. In the course of this, active involvement of citizens in planning political procedures is more and more supported electronically. The expectations culminate in the assumption that information and communication technology (ICT) can enhance civic participation and reduce disenchantment with politics. Out of these expectations, a lot of eparticipation projects were initiated in Germany. Initiatives were established, e.g. the "Initiative eParticipation", which gave many incentives of electronic participation for policy and administration in order to strengthen decision-making processes with internet supported participation practices. This thesis consists of two major parts. In the first part, definitions of the essential terms are presented. The position of e-participation within the dimension of ebusiness is pointed out. In order to explain e-participation, basics of the classical offline participation are delivered. It will be shown that a change is in progress, not only because of the deployment of ICT. Subsequently, a framework to characterize eparticipation is presented. The European Union is encouraging the implementation of e-participation. So, the city of Koblenz should be no exception. But what is the current situation in Koblenz? To provide an answer to this question, the status quo was examined with the help of a survey among the citizens of Koblenz, which was developed, conducted and evaluated. This is the second major part of this thesis.
This thesis conducts a text and network analysis of criminological files. The specific focus during the research is the field money laundering. The analysis showed the most important concepts present in the text which were classified in eleven different classes. The relationships of those concepts were analysed using ego networks, key entity identification and clustering. Some of the statements given about money laundering could be validated by the findings of this analysis and their interpretation. Specific concepts like banks and organizations as well as foreign subsidiaries were identified. Aggregating these concepts with the statements in chapter 1.4.3 on the circular process of money laundering it can be stated that different organizations and individuals, present in the criminological files, were placing money through different banks, organizations and investments in the legal financial market. At last this thesis tries to validate the benefits of the used tools for the kind of conducted research process. An estimation on ORA's and Automap's applicability for this kind of research is given in the end.
Abstract For a significant length of time, computer simulation programs have been the preferred tools of sociologists to analyse " thus confirm or refute " sociological theories, scenarios, presumptions and assumptions. Many different simulation platforms for various domains exist. The EmIL project aims to create a new simulation platform specifically to analyse norm emergence. This platform is divided into sections, thereby allowing the analysis of individual norm emergence: this is not currently possible, thus EmIL-S may represent a significant improvement over current simulation platforms. This diploma thesis describes the concepts behind the project and provides a prototype for the simulation program EmIL-S. The creation of the prototype and the underlying development process are described in detail. The experience gained during this process is analysed and described. In the course of this analysis, the malfunctions and errors within EmIL-S are explained; the solutions to these malfunctions and errors are noted, along with other proposed improvements. This diploma thesis can also be used as a helpful manual to build simulations within the simulation platform.
Die vorliegende Diplomarbeit untersucht die Emergenz eines gemeinsam genutzten Lexikons anhand einer Implementierung des Modells von Edwin Hutchins und Brian Hazlehurst. Zunächst erläutert diese Arbeit das oben genannte Modell und analysiert sowohl verschiedene Simulationstechniken, insbesondere die der Multi-Agenten-Simulation, als auch den Aufbau und die Funktionalität künstlicher neuronaler Netze, welche als Hauptbestandteile des Modells angesehen werden können. Der Modellbeschreibung folgen Entwurf, Architektur und eine detaillierte Erläuterung der Implementierung des Werkzeugs LexLearn. LexLearn ist ein in Java komplett neu konzipiertes und implementiertes Programm und bietet dem Benutzer die Möglichkeit, die Emergenz einer gemeinsam genutzten Sprache innerhalb verschiedener Agentengemeinschaften zu simulieren und zu analysieren. In mehreren Simulationsdurchläufen werden sowohl die Ergebnisse von Edwin Hutchins und Brian Hazlehurst reproduziert als auch weitere Erkenntnisse durch neu erstellte Simulationen gewonnen.
Multi-agent systems are a mature approach to model complex software systems by means of Agent-Oriented Software Engineering (AOSE). However, their application is not widely accepted in mainstream software engineering. Parallel to this the interdisciplinary field of Agent-based Social Simulation (ABSS) finds increasing recognition beyond the purely academic realm which starts to draw attention from the mainstream of agent researchers. This work analyzes factors to improve the uptake of AOSE as well as characteristics which separate the two fields AOSE and ABSS to understand their gap. Based on the efficiency-oriented micro-agent concept of the Otago Agent Platform (OPAL) we have constructed a new modern and self-contained micro-agent platform called µ². The design takes technological trends into account and integrates representative technologies, such as the functionally-inspired JVM language Clojure (with its Transactional Memory), asynchronous message passing frameworks and the mobile application platform Android. The mobile version of the platform shows an innovative approach to allow direct interaction between Android application components and micro-agents by mapping their related internal communication mechanisms. This empowers micro-agents to exploit virtually any capability of mobile devices for intelligent agent-based applications, robotics or simply act as a distributed middleware. Additionally, relevant platform components for the support of social simulations are identified and partially implemented. To show the usability of the platform for simulation purposes an interaction-centric scenario representing group shaping processes in a multi-cultural context is provided. The scenario is based on Hofstede's concept of 'Cultural Dimensions'. It does not only confirm the applicability of the platform for simulations but also reveals interesting patterns for culturally augmented in- and out-group agents. This explorative research advocates the potential of micro-agents as a powerful general system modelling mechanism while bridging the convergence between mobile and desktop systems. The results stimulate future work on the micro-agent concept itself, the suggested platform and the deeper exploration of mechanisms for seemless interaction of micro-agents with mobile environments. Last but not least the further elaboration of the simulation model as well as its use to augment intelligent agents with cultural aspects offer promising perspectives for future research.
In usage of information systems the maintenance of their actuality and their extensibility is of importance. There is a constant reoccurrence of situations, when these goals cannot be supported by keeping on the old system, the legacy system. A solution for that is its migration into a new environment. The migration of software is to be considered as a subdiscipline of software engineering, more precisely, as a part of software maintenance. In this thesis the reference migration process model ReMiP, introduced in another thesis of the institute, was applied. The goal of this examination is to bring this model to practice in a website migration project and to analyze its validity. Here, especially the subject of completeness and generalizability of the model for migration processes and the gathering of concrete experiences with the intensity of its activities is of interest. The target environment for the website migration will be the content management system Plone. Within this thesis it will be described thoroughly. Finally, the website to migrate will be brought to its new target environment. The result of this thesis is the migrated GXL-Website in the target system Plone using the ReMiP. By this migration, the ReMiP was successfully validated as a reference process model for software migrations.
