The analysis of knowledge construction in community based service-learning programmes for basic nursing education at two selected nursing schools in South Africa.Mthembu, Sindisiwe Zamandosi. January 2011 (has links)
Community based service-learning is one of the fastest growing reforms in higher education, especially in the field of health care. The increased interest in this phenomenon is based on the demands by government and society that higher education institutions should be more responsive to the needs of the community. Literature, however, reflects that service learning lacks a sound theoretical base to guide teaching and learning due to limited research in this area. This study was, therefore, aimed at exploring the phenomenon knowledge construction in basic nursing programmes in selected South African nursing schools with the intention to generate a middle range theory that may be used to guide the process of knowledge construction in community-based service-learning programmes. This study adopted a qualitative approach and a grounded theory research design
by Strauss and Corbin. Two university-based schools of nursing were purposively selected to participate in the study. There were a total number of 16 participants. The collection of data was intensified by the use of multiple sources of data (participant observation, documents analysis and in-depth structured interviews). The data analysis process entailed three phases; open, axial and selective coding. The results of the study revealed that the phenomenon “knowledge construction” is conceptualised as having specific core characteristics, which include the use of authentic health-related problems, academic coaching through scaffolding,
academic discourse-dialogue and communities of learners. The findings showed that there are a number of antecedent conditions and contextual circumstances contributing to how knowledge is constructed in a community based service learning programme. The process of knowledge construction emerged as cyclical in nature, with students, facilitators and community members having specific roles to play in the process. A number of intervening variables were identified that had an influence on the expected outcomes on knowledge construction in community based
service learning programmes. These findings led to the generation of a
conceptual model. Knowledge construction according to this model takes place in an environment which is characterised by interactive learning, collaborative learning, actively learning and inquiry-based learning through continuous reflective learning processes. The main concepts in this conceptual model include concrete learning experiences, continuous reflection, problem posing, problem analysis, knowledge deconstruction and knowledge generation, knowledge verification, knowledge generation, testing of generated knowledge and evaluation of generated knowledge. The sub-concepts include learning through senses, an initial situation, health-related triggers, social interaction, reflection-in action,
reflection-on action, hypotheses generation, conceptualisation of learning
experiences, information validation and community interventions.
Recommendations were categorised into education and training of academic staff, application of the model and further research with regard to quality assurance in CBSL programmes as well as the use of other research designs for similar studies. / Thesis (Ph.D.)-University of KwaZulu-Natal, Durban, 2011.

Potenzialanalyse der elektronischen Gesundheitskarte für einrichtungsübergreifende Behandlungswege aus der Perspektive der Patienten unter Berücksichtigung organisatorischer RahmenbedingungenBauer, Marcus 07 November 2014 (has links) (PDF)
Die demografische Entwicklung und die fachliche Spezialisierung medizinischer Organisationen führen zu immer komplexeren Behandlungswegen. Eine grundsätzliche Herausforderung komplexer Behandlungswege besteht darin, die Versorgungskontinuität zu wahren, obschon viele verschiedene Einrichtungen am Behandlungsweg agieren.
Die Versorgungskontinuität hängt dabei maßgeblich von einer effektiven Kooperation und effizienten Kommunikation der beteiligten Akteure ab. Die folgende Arbeit ist der Frage gewidmet, welches Potenzial die elektronische Gesundheitskarte (eGK) in diesem transinstitutionellen Szenario für die Patienten birgt.
Eine entscheidende Empfehlung im Rahmen des Requirements Engineering (RE) besteht darin, als Erstes die Anforderungen der Anwender zu analysieren und erst daran anschließend die Funktionalität des technischen Systems hinsichtlich der Anforderungskonformität zu evaluieren. Dieser Empfehlung folgend führte der Verfasser dieser Abhandlung dreizehn teilstrukturierte Interviews, fünf Projektsteuerungsmeetings und einen Workshop mit Patienten und medizinischen Experten durch, um fünf komplexe Behandlungswege aus der Perspektive der Patienten zu rekonstruieren. Die Auswertung, Strukturierung und Validierung der dem Behandlungskontext inhärenten Probleme mündeten in fünfundvierzig Einzelproblemen, die zu fünf finalen Patientenanforderungen verdichtet werden konnten. Im zweiten Schritt analysierte der Verfasser dieser Arbeit die Funktionalität der eGK hinsichtlich der Fähigkeit, diesen fünf Anforderungen gerecht zu werden. Die vorliegende Potenzialanalyse hebt sich von den bisherigen Forschungsarbeiten zur eGK insbesondere durch zwei Merkmale ab: Erstens erfolgt die Analyse konsequent aus der Perspektive der Patienten und zweitens sind dabei die organisatorischen Rahmenbedingungen intensiv berücksichtigt worden.
In dieser Abhandlung werden die Behandlungswege von fünf Patienten fallstudienbasiert aus einer ganzheitlichen Perspektive beleuchtet. Es wird gezeigt, dass fünf grundsätzliche Patientenanforderungen zu erfüllen sind. Diese fünf Anforderungen basieren auf Problemen, die erstens mit einer effizienten Informationslogistik, zweitens mit dem Recht auf informationelle Selbstbestimmung, drittens mit der Versorgungskontinuität, viertens mit der Gesamtsteuerung der Behandlung und fünftens mit administrativen Aufgaben zusammenhängen. Auf dieser Basis konnten insgesamt zehn Fachanwendungen identifiziert und im Rahmen eines visionären Anwendungsfalles exemplarisch veranschaulicht werden, von denen angenommen wird, dass sie das Potenzial der geplanten Telematik-Infrastruktur (TI) hinsichtlich der Anforderungen der Patienten besonders gut ausschöpfen.

Case based reasoning as an extension of fault dictionary methods for linear electronic analog circuits diagnosisPous i Sabadí, Carles 12 July 2004 (has links)
El test de circuits és una fase del procés de producció que cada vegada pren més importància quan es desenvolupa un nou producte. Les tècniques de test i diagnosi per a circuits digitals han estat desenvolupades i automatitzades amb èxit, mentre que aquest no és encara el cas dels circuits analògics. D'entre tots els mètodes proposats per diagnosticar circuits analògics els més utilitzats són els diccionaris de falles. En aquesta tesi se'n descriuen alguns, tot analitzant-ne els seus avantatges i inconvenients.Durant aquests últims anys, les tècniques d'Intel·ligència Artificial han esdevingut un dels camps de recerca més importants per a la diagnosi de falles. Aquesta tesi desenvolupa dues d'aquestes tècniques per tal de cobrir algunes de les mancances que presenten els diccionaris de falles. La primera proposta es basa en construir un sistema fuzzy com a eina per identificar. Els resultats obtinguts son força bons, ja que s'aconsegueix localitzar la falla en un elevat tant percent dels casos. Per altra banda, el percentatge d'encerts no és prou bo quan a més a més s'intenta esbrinar la desviació.Com que els diccionaris de falles es poden veure com una aproximació simplificada al Raonament Basat en Casos (CBR), la segona proposta fa una extensió dels diccionaris de falles cap a un sistema CBR. El propòsit no és donar una solució general del problema sinó contribuir amb una nova metodologia. Aquesta consisteix en millorar la diagnosis dels diccionaris de falles mitjançant l'addició i l'adaptació dels nous casos per tal d'esdevenir un sistema de Raonament Basat en Casos. Es descriu l'estructura de la base de casos així com les tasques d'extracció, de reutilització, de revisió i de retenció, fent èmfasi al procés d'aprenentatge.En el transcurs del text s'utilitzen diversos circuits per mostrar exemples dels mètodes de test descrits, però en particular el filtre biquadràtic és l'utilitzat per provar les metodologies plantejades, ja que és un dels benchmarks proposats en el context dels circuits analògics. Les falles considerades son paramètriques, permanents, independents i simples, encara que la metodologia pot ser fàcilment extrapolable per a la diagnosi de falles múltiples i catastròfiques. El mètode es centra en el test dels components passius, encara que també es podria extendre per a falles en els actius. / Testing circuits is a stage of the production process that is becoming more and more important when a new product is developed. Test and diagnosis techniques for digital circuits have been successfully developed and automated. But, this is not yet the case for analog circuits. Even though there are plenty of methods proposed for diagnosing analog electronic circuits, the most popular are the fault dictionary techniques. In this thesis some of these methods, showing their advantages and drawbacks, are analyzed.During these last decades automating fault diagnosis using Artificial Intelligence techniques has become an important research field. This thesis develops two of these techniques in order to fill in some gaps in fault dictionaries techniques. The first proposal is to build a fuzzy system as an identification tool. The results obtained are quite good, since the faulty component is located in a high percentage of the given cases. On the other hand, the percentage of successes when determining the component's exact deviation is far from being good.As fault dictionaries can be seen as a simplified approach to Case-Based Reasoning, the second proposal extends the fault dictionary towards a Case Based Reasoning system. The purpose isnot to give a general solution, but to contribute with a new methodology. This second proposal improves a fault dictionary diagnosis by means of adding and adapting new cases to develop aCase Based Reasoning system. The case base memory, retrieval, reuse, revise and retain tasks are described. Special attention to the learning process is taken.Several circuits are used to show examples of the test methods described throughout the text. But, in particular, the biquadratic filter is used to test the proposed methodology because it isdefined as one of the benchmarks in the analog electronic diagnosis domain. The faults considered are parametric, permanent, independent and simple, although the methodology can be extrapolated to catastrophic and multiple fault diagnosis. The method is only focused and tested on passive faulty components, but it can be extended to cover active devices as well.

Raisonnement par règles et raisonnement par cas pour la résolution des problèmes en médecine / Rule-based and case-based reasoning for medical problem solvingSteichen, Olivier 07 December 2013 (has links)
Les médecins cherchent à résoudre les problèmes de santé posés par des individus. Une solution individualisée tient compte de la singularité du patient concerné. L'individualisation des pratiques est-elle possible et souhaitable? Le cas échéant, selon quelles modalités peut-elle ou doit-elle être réalisée'? La première partie de la thèse vise à montrer: que la question se pose depuis les premières théories de la décision médicale (Hippocrate) ; qu'elle s'est posée de façon aiguë au début du XIX" siècle, avec l'apparition des études statistiques; et que l'observation médicale et son évolution concrétisent la façon dont la documentation des cas et leur individualisation interagissent. La deuxième partie reprend la question dans le contexte contemporain, à travers la naissance de l'"evidence-based medicine", ses critiques et son évolution. La troisième partie montre que l'articulation du raisonnement par règles et du raisonnement par cas modélise de façon opérationnelle une démarche raisonnée d'individualisation des décisions médicales. Ce modèle simple permet de rendre compte du mouvement d'aller-retour entre deux conceptions de l'individualisation et d'en proposer une version équilibrée, mise à l'épreuve dans les domaines de l'évaluation des pratiques et de la littérature médicale. / Physicians try to solve health problems of individual patients. Customized solutions take into account the uniqueness of the patient. Is the individualization of medical decisions possible and desirable'? If so, how can I tor should it be performed? The first part of the thesis shows: that the question arises since the first conceptualizations of medical reasoning (Hippocrates); that is was much debated in the early nineteenth century, when statistical studies were first performed to guide medical decisions; and that the medical observation and its evolution materialize how case documentation and management interact. The second part addresses the issue in the current context, from the birth of evidence-based medicine, its cri tics and its evolution. The third part shows that linking rule-based and case-based reasoning adequately pictures the process of customizing medical decisions. This simple model can account for the movement between two kinds of customization and leads to a balanced approach, tested in the field of practice evaluation and medical literature.

Modelo de apoio ao estudo de pacientes em oncologia pediátrica utilizando raciocínio baseado em casos e mineração de dados / Model study support for patients in pediatric oncology using case-based reasoning and data miningCruz, Jailton Cardoso da 14 April 2014 (has links)
This work aims to propose a recommendation model of prescription items for Pediatric Oncology based on data extraction from Electronic Patient Record. These data are used as indexed cases to aid providers of medical service based on the similarity of prescriptions, according to the patient's history. From the viewpoint of aid medical education, the modeling objective support the student or health professional in understanding the decision-making process during the prescription items oncological medical treatment, for example drugs, laboratory exams or images exams, diet, gases, care, chemotherapy, radiotherapy. To develop the model, was used the approach of Case Based Reasoning (CBR), through the representation of prescription medical base-case, indexed by their treatment items. During the recovery phase of cases, we used the tool. Data Mining by applying the model of association rule, together with the algorithm "apriori" for obtaining the similarity between cases. To update the case base, a procedure database for performing the process of Extraction, Transformation and Load of the database was developed. The developed model was applied in the database of the Electronic Patient Record of the Santa Casa de Misericordia de Maceio, based on Hospital Management Systems “MV Sistemas”, deployed in the unit since 2005. For the presentation of results, was used the Oracle Data Miner tool, which allowed access to the database and analysis of selected cases by identifying key words contained in the evolution of the clinical condition of the patient. The application of the experiments validate the occurrence of allowed combined application of items of treatment according to the keywords, which can be used as input in the process of making medical decision and tutoring. / Este trabalho tem como objetivo propor um Modelo de Recomendação de itens de prescrição para Oncologia Pediátrica baseado na extração de dados do Prontuário Eletrônico do Paciente. Esses dados são utilizados como casos indexados, para auxiliar os prestadores de serviço médico baseados na similaridade de prescrições, de acordo com o histórico do paciente. Do ponto de vista do apoio a educação médica, a modelagem objetiva apoiar o estudante ou o profissional de saúde no entendimento do processo de tomada de decisão durante a fase de prescrição de itens de tratamento médico oncológico, como, por exemplo: medicamentos, exames de laboratório ou de imagens, dieta, gases, cuidados, quimioterapia, radioterapia. Para o desenvolvimento do modelo, utilizou-se a abordagem de Raciocínio Baseado em Casos (RBC), através da representação de uma base de casos de prescrição médica, indexada por seus itens de tratamento. Durante a fase de recuperação de casos, utilizou-se a ferramenta de Mineração de Dados aplicando-se o modelo de regra de associação, em conjunto com o algoritmo “apriori” visando a obtenção da similaridade entre casos. Para a atualização da base de casos, foi desenvolvido um procedimento de banco de dados para execução do processo de Extração, Transformação e Carga da base de dados. O modelo desenvolvido foi aplicado na base de dados do Prontuário Eletrônico do Paciente da Santa Casa de Misericórdia de Maceió, baseado no sistema de gestão hospitalar MV Sistemas, implantado na unidade desde 2005. Para a apresentação dos resultados, utilizou-se a ferramenta Oracle Data Miner, que possibilitou o acesso ao banco de dados e a análise dos casos selecionados pela identificação de palavras chaves contidas na evolução do estado clínico do paciente. A aplicação dos experimentos permitiu validar a ocorrência de aplicação conjunta de itens de tratamento de acordo com as palavras chaves, o que pode ser utilizado como elemento para o processo de tomada de decisão médica e tutoria.

Outils d'élaboration de stratégie de recyclage basée sur la gestion des connaissances : application au domaine du génie des procédés / Tools of elaboration of strategy of waste recycling based on knowledge management : application on process engineeringChazara, Philippe 06 November 2015 (has links)
Dans ce travail, une étude est réalisée sur le développement d'une méthodologie permettant la génération et l'évaluation de nouvelles trajectoires de valorisation pour des déchets. Ainsi, pour répondre à cette problématique, trois sous problèmes ont été identifiés. Le premier concerne un cadre de modélisation permettant la représentation structurée et homogène de chaque trajectoire, ainsi que les indicateurs choisis pour l'évaluation de ces dernières, permettant une sélection ultérieure. Le deuxième se concentre sur le développement d'une méthodologie puis la réalisation d'un outil permettant la génération de nouvelles trajectoires en s'appuyant sur d'autres connues. Enfin, le dernier sous problème concerne le développement d'un second outil développé pour modéliser et estimer les trajectoires générées. La partie de création d'un cadre de modélisation cherche à concevoir des structures globales qui permettent la catégorisation des opérations unitaires sous plusieurs niveaux. Trois niveaux de décomposition ont été identifiés. La Configuration générique de plus haut niveau, qui décrit la trajectoire sous de grandes étapes de modélisation. Le second niveau, Traitement générique propose des ensembles de structures génériques de traitement qui apparaissent régulièrement dans les trajectoires de valorisation. Enfin, le plus bas niveau se focalise sur la modélisation des opérations unitaires. Un second cadre a été créé, plus conceptuel et comportant deux éléments : les blocs et les systèmes. Ces cadres sont ensuite accompagnés par un ensemble d'indicateurs choisis à cet effet. Dans une volonté d'approche de développement durable, un indicateur est sélectionné pour chacune de des composantes : économique, environnemental et social. Dans notre étude, l'impact social se limite à l'estimation du nombre d'emplois créés. Afin de calculer cet indicateur, une nouvelle approche se basant sur les résultats économiques d'une entreprise a été proposée et validée.L'outil de génération de nouvelles trajectoires s'appuie sur l'utilisation de la connaissance en utilisant un système de raisonnement à partir de cas (RàPC). Pour être adapté à notre problématique, la mise en œuvre de ce dernier a impliqué la levée de plusieurs points délicats. Tout d'abord, la structuration des données et plus largement la génération de cas sources sont réalisées par un système basé sur des réseaux sémantiques et l'utilisation de mécanismes d'inférences. Le développement d'une nouvelle méthode de mesure de similarité est réalisé en introduisant la notion de définition commune qui permet de lier les états, qui sont des descriptions de situations, à des états représentant des définitions générales d'un ensemble d'états. Ces définitions communes permettent la création d'ensembles d'états sous différents niveaux d'abstraction et de conceptualisation. Enfin, un processus de décompositions des trajectoires est réalisé afin de résoudre un problème grâce à la résolution de ses sous-problèmes associés. Cette décomposition facilite l'adaptation des trajectoires et l'estimation des résultats des transformations. Basé sur cette méthode, un outil a été développé en programmation logique, sous Prolog. La modélisation et l'évaluation des voies de valorisation se fait grâce à la création d'outil spécifique. Cet outil utilise la méta-programmation permettant la réalisation dynamique de modèle de structure. Le comportement de ces structures est régi par la définition de contraintes sur les différents flux circulants dans l'ensemble de la trajectoire. Lors de la modélisation de la trajectoire, ces contraintes sont converties par un parser permettant la réalisation d'un modèle de programmation par contraintes cohérent. Ce dernier peut ensuite être résolu grâce à des solveurs via une interface développée et intégrée au système. De même, plusieurs greffons ont été réalisés pour analyser et évaluer les trajectoires à l'aide des critères retenus. / In this work, a study is realised about the creation of a new methodology allowing the generation and the assessment of new waste recovery processes. Three elements are proposed for that. The first one is the creation of a modelling framework permitting a structured and homogeneous representation of each recovery process and the criteria used to asses them. The second one is a system and a tool generating new recovery processes from others known. Finally, the last element is another tool to model, to estimate and to asses the generated processes. The creation of a modelling framework tries to create some categories of elements allowing the structuring of unit operations under different levels of description. Three levels have been identified. In the higher level, the Generic operation which describes global structure of operations. The second one is Generic treatment which is an intermediate level between the two others. It proposes here too categories of operations but more detailed than the higher level. The last one is the Unit operation. A second framework has been created. It is more conceptual and it has two components : blocs and systems. These frameworks are used with a set of selected indicators. In a desire of integrating our work in a sustainable development approach, an indicator has been chosen for each of its components: economical, environmental and social. In our study, the social impact is limited to the number of created jobs. To estimate this indicator, we proposed a new method based on economical values of a company. The tool for the generation of new waste recovery processes used the methodology of case-based reasoning CBR which is based on the knowledge management. Some difficult points are treated here to adapt the CBR to our problem. The structuring of knowledge and generally the source case generation is realised by a system based on connections between data and the use of inference mechanisms. The development of a new method for the similarity measure is designed with the introduction of common definition concept which allows linking states, simply put description of objects, to other states under different levels of conceptualizations and abstractions. This point permits creating many levels of description. Finally, recovery process is decomposed from a main problem to some sub-problems. This decomposition is a part of the adaptation mechanism of the selected source case. The realisation of this system is under logic programming with Prolog. This last one permits the use of rules allowing inferences and the backtracking system allowing the exploration to the different possible solution. The modelling and assessment of recovery processes are done by a tool programmed in Python. It uses the meta-programming to dynamically create model of operations or systems. Constraint rules define the behaviour of these models allowing controlling the flux circulating in each one. In the evaluation step, a parser is used to convert theses rules into a homogeneous system of constraint programming. This system can be solved by the use of solvers with an interface developed for that and added to the tool. Therefore, it is possible for the user to add solvers but also to add plug-ins. This plug-ins can make the assessment of the activity allowing to have different kinds of evaluation for the same criteria. Three plug-ins are developed, one for each selected criterion. These two methods are tested to permit the evaluation of the proposed model and to check the behaviour of them and their limits . For these tests, a case-base on waste has been created Finally, for the modelling and assessment tool, a study case about the recovery process of used tyres in new raw material is done.

Assessment of case-based integrated learning as a part of dental curriculum reformNadershahi, Nader A. 01 January 2011 (has links)
There has been a growing call for change in the management of dental education programs, and, in response to this call, the faculty and staff at the University of the Pacific Arthur A. Dugoni School of Dentistry developed the Pacific Dental Helix Curriculum management model. The first major component of this curriculum was the development of the Integrated Clinical Science Strand of the Helix focused on multidisciplinary and case-based andragogies. The mixed method research design was used to identify common aspects of Case-Based Learning and multi-disciplinary teaching through a qualitative analysis of curricular materials and to analyze their impact on selected student outcomes of pre and post-change through statistical analysis. The outcomes chosen for the quantitative portion were surrogate measures of National Board Scores and grade point averages to represent knowledge and skills. The overall analysis of the quantitative data shows negligible impact on the outcomes being measured. We know from the literature that active learning models motivate and engage students at a higher level in their learning and better prepare them to solve problems creatively versus a traditional educational model, so it is significant to see that there were no decreases in performance with a move to a more engaging curriculum. This study offers foundational information for future curriculum design, pedagogy, and assessment.

Erweiterungen des fallbasierten Schließens zur prognostischen Fundierung von Planungsaufgaben - Konzeption und prototypische Implementierung am Beispiel von Kapazitätsnachfrageprognosen zur Fundierung der Kapazitätsplanung auf verschiedenen Ebenen hochschulinterner PlanungssystemePöppelmann, Daniel 09 March 2015 (has links)
In der vorliegenden Arbeit wird das Konzept eines zusammengesetzten Decision Support Systems (DSS), bestehend aus einer wissensgetriebenen und einer datengetriebenen Komponente vorgeschlagen, welches Entscheidungsträger der Kapazitätsplanung auf verschiedenen Ebenen eines hochschulinternen Planungssystems mit prognostizierten, den Kernprozess Lehre betreffenden Nachfragegrößen unterstützt.
Den Kern des zusammengesetzten DSS stellt eine wissensgetriebene Komponente dar, die basierend auf dem Paradigma des Case-based Reasoning (CBR) die Prognose individueller Studienverläufe aller Studierender einer Hochschule ermöglicht. Dazu erfolgt die Wiederverwendung von Erfahrungen hinsichtlich der Modul- und Klausurbelegung von Alumni und im Studium fortgeschrittener Studierender, die in Form von Fällen repräsentiert werden. Die domänenspezifischen Anpassungen und Erweiterungen des Paradigmas des CBR umfassen erstens die Repräsentation von Erfahrungen mit heterogenem Zeitbezug durch Fälle. Diesbezüglich wird einerseits eine dynamische, vom zu lösenden Problem abhängige Zuordnung von Fallattributen zu den Komponenten Beschreibung und Lösung eines Falls konzipiert. Andererseits wird eine Möglichkeit zur Abbildung von zeitabhängigen Attributen sowohl in der Beschreibung als auch in der Lösung eines Falls geschaffen. Zweitens erfolgt eine Erweiterung des CBR-cycle, des Problemlösungsprozesses, der im erarbeiteten Konzept zur Erstellung von Prognosen verwendet wird. Die Erweiterungen umfassen insbesondere die automatisierte Erkennung von zu lösenden (Prognose-)Fällen, die Überprüfung und Anpassung erstellter Prognosen mithilfe eines regelbasierten Systems, das sich auf Domänenwissen aus einer Ontologie stützt, sowie die zeitasynchrone Einbeziehung einer Vielzahl von Studierenden als Domänenexperten zur Anpassung individuell prognostizierter Studienverläufe.
Eine datengetriebene Komponente bildet den zweiten Teil des zusammengesetzten DSS. Diese dient der Bereitstellung der Ergebnisse der wissensgetriebenen Komponente in einer von Entscheidungsträgern der hochschulinternen Kapazitätsplanung verwertbaren Form. Die durch die wissensgetriebene Komponente erstellten Prognosen werden hierzu in einen multidimensional modellierten Data Mart geladen und mithilfe von analytischen und Standardberichten auf verschiedenen Aggregationsniveaus zur Auswertung bereitgestellt.
Zur Evaluation des Konzepts erfolgt dessen prototypische Implementierung am Beispiel der Universität Osnabrück. Der Fokus der Bewertung liegt auf dem Kriterium der Prognosegenauigkeit, welches durch verschiedene, auf dem Prognosefehler basierende Gütemaße operationalisiert wird. Letztere werden anhand von Prognosesimulationen mittels des Prototyps ermittelt und auf Basis eines Interpretationsschemas sowie durch Gegenüberstellung mit den Ergebnissen eines Referenzverfahrens interpretiert und bewertet.
