No. of bitstreams: 0 Previous issue date: 2010 / Nas últimas décadas, os gastos crescentes no setor saúde vêm preocupando diversos países, em especial aqueles cuja atenção à saúde é garantida pelo setor público. A grande pressão pela incorporação de tecnologias cada vez mais caras, além de impactar no orçamento dos países, produz restrição ao acesso dos serviços de saúde, visto que não é possível garantir todas as intervenções a todos. Diante desta situação, técnicas para a racionalização dos gastos, tais como as análises econômicas em saúde, são utilizadas na tentativa de maximizar a saúde, mas resguardando a viabilidade financeira dos sistemas públicos de saúde. Países desenvolvidos com forte financiamento público, assim como Austrália, Canadá e Reino Unido têm empregado cada vez mais estas ferramentas para a tomada de decisão acerca da incorporação de novas tecnologias. O Brasil, na última década, também tem empreendido esforços para a adoção de critérios de custo-efetividade, tanto na entrada de medicamentos no mercado privado, com a alteração da lei de registro e com a criação da Câmara de Regulação do Mercado de Medicamentos (CMED), quanto com o estabelecimento de uma Comissão de Incorporação de Tecnologias do Ministério da Saúde (CITEC). As decisões da CITEC são subsidiadas por estudos desenvolvidos pela área de Avaliação de Tecnologias em Saúde (ATS) do Departamento de Ciência e Tecnologia (DECIT) do Ministério da Saúde. Neste aspecto, as Agências Nacionais de Vigilância Sanitária e de Saúde Suplementar também instituíram áreas de ATS para responder as suas demandas. E, apesar do avanço na institucionalização de áreas que utilizam análises econômicas na incorporação de tecnologias, ainda há uma fragilidade institucional nas etapas seguintes do ciclo de vida destas. O País também carece de profissionais capacitados e padece de uma desorganização neste campo causa da principalmente pela sobreposição de atividades e atribuições das áreas que realizam a ATS no governo federal. Ademais, para que as análises econômicas em saúde sejam realmente úteis na tomada de decisão é imprescindível a definição de um limite custo-efetividade para o Brasil. / In recent decades, increasing spending in the health sector is worrying many countries, particularly those whose health care is guaranteed by the public sector. The big push for the incorporation of technologies increasingly expensive is impacting the budgets of countries and producing a restriction on access to health services, since we cannot guarantee all interventions for everybody. Facing this situation, techniques for the rationalization of expenditures, such as health economic analysis, are used in an attempt to maximize health, but protecting the financial viability of public health systems. Developed countries with strong public support, such as Australia, Canada and the UK have progressively more used this tool for decision making regarding the incorporation of new technologies. Brazil, more recently, has also made efforts to adopt criteria of cost-effectiveness, both at the entrance of drugs in the private market, with the adjustment of the law of register and the establishment of the Board of Market Regulation of Medicines (CMED) and the Commission of Technology Incorporation of the Ministry of Health (CITEC). The decisions of CITEC are subsidized by studies undertaken by the area of Health Technology Assessment (HTA) at Department of Science and Technology (DECIT) of the Ministry of Health. The Brazilian Health Surveillance Agency and Brazilian National Private Health Insurance Agency also established areas of HTA to answer to their demands. Despite advances in the institutionalization of areas that use economic analysis in the incorporation of technologies, there is fragility in the following stages of the life cycle of these. The country also lacks qualified professionals and suffers from a disruption in this field mainly caused by overlapping of activities and tasks of the areas that hold the HTA in the Federal Government. Moreover, for the health economic analyses are really useful in decision making is essential to define threshold costeffectiveness for Brazil.

Urban rail transport systems play a vital role in providing efficient and sustainable mobility solutions for growing metropolitan areas. This thesis focuses on the case of Stockholm's urban rail transport, managed by Region Stockholm, which serves nearly 900,000 daily passengers amid rapid population growth. However, the aging power supply system poses challenges to the system's efficiency and capacity expansion. To address these issues, this study develops cost modeling and decision-making tools aimed at evaluating future energy-saving business cases within the urban rail transport system. These tools, though preliminary, provide decision-makers with a techno-economic perspective to compare the cost-effectiveness of various measures and inform future interventions. The research methodology involves a system engineering approach, with continuous collaboration between the academic institution (KTH), transport authority (TF), and industrial partner (MTR). Weekly meetings facilitated the understanding of the urban rail transport system and the development of a decision-making algorithm. The study identifies stakeholders, primarily TF and passengers, and outlines a decision-making framework to assess proposed business cases. The tools generated undergo validation through expert feedback, laying the foundation for future empirical testing. Key findings highlight two main methods for energy-saving measures: technological modifications (e.g., Energy Storage Systems - ESS) and operational adjustments. Both On board and Wayside ESS installations demonstrate significant energy-saving potential, while operational adjustments such as HVAC modifications present challenges in automation. Qualitative reviews were made on these measures. The thesis proposes a preliminary Decision Making Tool to quantify Key Performance Indicators (KPIs) and facilitate informed decision making. Future work includes expanding stakeholder inclusion, refining cost models, and integrating additional business cases into the decision-making framework. In conclusion, this thesis contributes to the understanding of cost-effective measures for enhancing energy efficiency within urban rail transport systems. The developed tools offer an initial approach for decision-makers to navigate complex trade-offs and prioritize interventions, ultimately contributing to the sustainability and resilience of urban mobility infrastructure. / Järnvägstransportsystem i städerna spelar en viktig roll för att tillhandahålla effektiva och hållbara mobilitetslösningar för växande storstadsområden. Detta examensarbete fokuserar på fallet med Stockholms stadstrafik, som drivs av Region Stockholm, som servar nästan 900 000 dagliga passagerare i en snabb befolkningstillväxt. De åldrande strömförsörjningssystemen innebär dock utmaningar för systemets effektivitet och kapacitetsutbyggnad. För att ta itu med dessa frågor, utvecklar denna studiekostnadsmodellering och beslutsfattande verktyg som syftar till att utvärdera framtida energibesparande affärscases inom det urbana järnvägstransportsystemet. Dessa verktyg, även om de är preliminära, ger beslutsfattare ett tekniskt-ekonomiskt perspektiv för att jämföra kostnadseffektiviteten för olika åtgärder och informera framtida insatser. Forskningsmetodiken innebär ett systemtekniskt tillvägagångssätt, med kontinuerligt samarbete mellan den akademiska institutionen (KTH), transportmyndigheten (TF) och industriell partner (MTR). Veckomöten underlättade förståelsen av det urbana järnvägstransportsystemet och utvecklingen av en beslutsalgoritm. Studien identifierar intressenter, främst TF och passagerare, och skisserar en ram för beslutsfattande för att bedöma föreslagna affärsfall. Verktygen som genereras genomgår validering genom expertfeedback, vilket lägger grunden för framtida empiriska tester. Nyckelresultat belyser två huvudmetoder för energibesparande åtgärder: tekniska modifieringar (t.ex. Energy Storage Systems - ESS) och driftsanpassningar. Både ESS-installationer ombord och längs vägen uppvisar betydande energibesparingspotential, medan operativa justeringar som HVAC-modifieringar innebär utmaningar inom automatisering. Kvalitativa granskningar gjordes av dessa åtgärder. Avhandlingen föreslår ett preliminärt beslutsfattande verktyg för att kvantifiera Key Performance Indicators (KPI:er) och underlätta välgrundat beslutsfattande. Framtida arbete inkluderar att utöka inkluderingen av intressenter, förfina kostnadsmodeller och integrera ytterligare affärscase i beslutsfattandet. Sammanfattningsvis bidrar detta examensarbete till förståelsen av kostnadseffektiva åtgärder för att förbättra energieffektiviteten inom stadstrafiksystem. De utvecklade verktygen erbjuder ett första tillvägagångssätt för beslutsfattare att navigera i komplexa avvägningar och prioritera insatser, vilket i slutändan bidrar till hållbarheten och motståndskraften hos mobilitetsinfrastrukturen i städerna.

The study goes beyond knowledge existing in the literature study of the philosophy and theory of knowledge, knowledge management, African knowledge and the management of knowledge by African institutions, including the peace and security architecture of Africa, to reveal a coherent conceptual framework and themes to guide the field research. During the field studies of specific cases in the Great Lakes region of Africa, principles and practices emerged that formed a framework for a constructed Trans-dimensional Knowledge Management Model (TDKM-M) to develop a theoretical model for the management of knowledge for conflict resolution as the first step towards the revival of Africa. The study proposes practical solutions for the management of knowledge that would empower decisionmakers to intervene successfully in conflict situations. Furthermore, the study serves to expand the knowledge base in the field of trans-disciplinary African studies, transcending the boundary between political science and epistemology to navigate the middle ground between disciplines and the space that lies beyond all disciplines and dichotomised thinking towards a new holistic understanding. A systems approach using MIT (multi-disciplinarity, interdisciplinarity and trans-disciplinarity) and qualitative research methodology on a transnational level was followed. The study consists of a literature study and a field study consisting of a pilot study, semi-structured interviews and participation in communities of practice to access the worldviews of diverse cultures. An observable knowledge dimension, consisting of a normative foundation, empirical knowledge domain and analytical knowledge domain, is identified. Furthermore, a tacit metaphysical knowledge dimension is identified that is informed by the observable dimension. The two dimensions transacts with each other to attain a higher level of trans-dimensional knowledge. The TDKM-M proposes principles and practices of how trans-dimensional knowledge, including indigenous African knowledge and external knowledge, can be managed in a collective middle ground to produce holistic understanding. This higher level of understanding can activate intervention into the causes and consequences of conflict. Innovation of African society could follow, achieving desired outcomes such as peace, justice, human rights, self-empowerment and innovation towards transformative growth, competitiveness and negotiate equilibrium with the global community, and ultimately the revival of Africa. / Political Sciences / D.

Diese Arbeit erklärt anhand von Vertragswerkstätten der Volkswagen AG, wie Kfz-Handwerker im komple-xen Feld Werkstatt Probleme lösen. Sie deckt auf, wie und warum Kfz-Handwerker auf besondere Weise Denken und Handeln. Dies meint, wie sie arbeiten, lernen und vor Allem, wie und warum sie Medien an-eignen – oder verweigern: Täglich diagnostizieren und reparieren Kfz-Handwerker Fahrzeuge. Dabei ist oft zu beobachten, dass extra dafür hergestellte Hilfsmedien von ihnen umgangen oder gar offen abgelehnt werden. Dies führt teils zu schweren Fehlern, teils aber auch zu herausragenden Leistungen. Bislang ist kaum geklärt, aus welchen Gründen dies erfolgt. Von den Handwerkern genannte Gründe er-scheinen in der Außenperspektive oft sonderbar. Doch sie sind subjektiv vernünftig. Die Untersuchung zeigt, mit welchen Begründungen die Handwerker sich gegen Medienaneignung entscheiden. Und sie er-klärt, inwiefern dies daran liegt, dass Computer im Spannungsverhältnis zwischen den Expertise-Denk¬wei-sen der Handwerker und den sozialen Beziehungen der Akteure stehen. Die Akteure sind Mitarbeiter im Autohaus, aber auch beim Hersteller und beim Importeur des jew. Landes. Dies gelingt durch die theoretische Basis subjektwissenschaftlicher Lerntheorie, unter Bezugnahme auf wissenschaftliche Nachbardisziplinen und mit der Methodologie, Strategie und Methodik qualitativer So-zialforschung. Die Phänomene werden exemplarisch aus mehrwöchigen Feldstudien in Werkstätten der Volkswagen AG in Deutschland qua O-Ton-Audiomittschnitt, Interview und Beobachtung rekonstruiert und mit begleitenden Quellen ergänzt. So entstehen z.B. Modelle - zur Typologie intuitiver und analytischer Arbeitsstrategien der Handwerker - zu Reflexionsauslösern - zu Medienkontakthürden und - zur Medien(vertrauens)bewertung im Prozess der Medienkompetenzentwicklung. Durch diese erstmals in solcher Form geleistete Phänomen-Aufschlüsselung werden - neue Ansatzpunkte des didaktischen Designs - und für die technische Redaktion - Herausforderungen an Medien und Prozesse - und für die Qualitätssteigerung zwingend zu leistende Aufgaben aufgezeigt. Es werden fast banal scheinende, subtile alltägliche Phänomene analysiert und deren massiver Einfluss auf Fehler und Erfolge des Handelns verdeutlicht. Da ersteres oberflächlich altbekannt und oft unhinterfragt ist, wird die große Bedeutung für einen erfolgreichen Reparaturprozess zumeist übersehen. Darum bietet sich hier noch ungenutztes Verbesserungs-Potential. Die Befunde fokussieren auf deutsche ‚Werkstattlogik‘, sind aber mit kritischem Rückbezug auf kulturelle Besonderheiten auf die Volkswagen AG Vertragswerkstätten in über 150 Ländern anwendbar.:Inhalt Auf einen Blick – Zusammenfassung und Schlagworte Aufbau der Kapitel 1 Einleitung 1 1.1 Problemstellung und Einleitung in das Phänomenfeld – die Herausforderung Werkstatt 1 1.2 Settingbeschreibung – das Szenario Werkstatt 4 1.3 Verwertungsziele – die Handreichungen für Redaktion, Computer und Forschungsgemeinschaft 5 1.4 Fragestellung – die Aneignung der Handwerker 6 1.5 Forschungsstrategie – der Analyseverlauf 7 1.5.1 Grounded Theory 7 1.5.2 Aufbau der Analyse 13 2 Exploration 15 2.1 Sensibilisierendes Konzept ad hoc – die ersten Überlegungen 15 2.2 Pädagogische Basis – die Ausgangs-Modelle als Integral der Analyse 16 2.2.1 Mediendidaktische Klassifikation – die Gegenstandsbeschreibung 16 2.2.2 Subjektwissenschaftliche Lerntheorie – das Integral der Theoriefolien 20 2.2.3 Mentale Modelle – die Erweiterung des Integrals um ein Bindeglied zu Experten-Begründungen 28 2.2.4 IT-Design, Medienkompetenz und Medienaneignung – die Erweiterung des Integrals um Bindeglieder zum Computer 32 2.3 Forschungs-Stand – der Status quo und neue Perspektiven als Anregung für die Analyse 39 2.3.1 Studien direkt zum Phänomen Medien und Werkstatt 40 2.3.2 Offene Fragen in der Praxisdisziplin Technische Redaktion 58 2.3.3 Offene Fragen zum Gestaltungswissen pädagogischer Psychologie 67 2.3.4 Technik im Forschungsfeld IT-Design 74 2.3.5 Didaktische Aspekte des Lernens und Wissens außerhalb von Lehr-Lern-Institutionen 91 2.3.6 Arbeitsobjekt, Subjekt und Feld in der komplexen Problemlöseforschung 105 2.3.7 Subjektsicht in Expertiseforschung, Routinen und Standards 115 2.3.8 Intuition und Analyse durch Forschung zum natürlich-intuitiven Entscheiden 136 2.3.9 Fehler-Forschung und Human Factors 156 2.3.10 Hochverlässlichkeit und Hochleistung in Gruppen 168 2.3.11 Soziodynamik 176 2.3.12 Forschung zur Vergemeinschaftung bei Lernen und e-Learning 180 2.4 Sensibilisierendes Konzept a priori – die Zusammenführung zu Suchsonden 195 2.5 Forschungs-Design – der Bau der Werkzeuge 198 2.5.1 Methodologie, Gütekriterien und Folgerungen 198 2.5.2 Methodik und Instrumentarium 202 3 Ergebnis 216 3.1 Aufbau der Ergebnisdarstellung 216 3.2 Werkstattlogik – das Konzept a posteriori als Befunde zu den Phänomenen und abgeleitete Prinzipien 218 3.2.1 Bekannte didaktische Faktoren 218 3.2.2 Kontext 220 3.2.3 Arbeitsstrategien der Handwerker 237 3.2.4 Begründungslogik intuitiv-heuristischer Arbeitsstrategie 247 3.2.5 Entscheidungsfaktoren für Arbeitsstrategien 272 3.2.6 Medienkollaboration und Medienaneignung 292 3.3 Antworten – die Auflösung der Fragestellung und didaktische Schlussfolgerungen 321 3.3.1 Kompression – die Rekapitulation der Frage und die verdichtete Antwort 321 3.3.2 Extrakt – die Zusammenschau der Befunde als Checkliste 323 3.3.3 Rahmen – die Zentralsätze als Meta-Modell 331 3.3.4 Effekt – die durch die Phänomene erzeugten Medienkontakthürden 332 3.4 Ausblick – die Diskussion der Ergebnisse und die Desiderata an die Forschungsgemeinschaft 333 Appendix Eins 336 A1 Literatur 336 A2 Abbildungen 365 A3 Abkürzungen 366 Appendix Zwei 369 A4 Empirische Quellen 369 A4.1 Codings pro Phänomen 369 A4.2 Analysierte Dokumente 402 A4.3 Transkripte 402 A4.4 MAXQDA-Files 402 A5 Ausgelagerte Details des Instrumentariums 403 A5.1 Interview-Leitfaden 403 A5.2 Transkriptionssystem 408 A5.3 Nicht eineindeutige Abkürzungen der rekonstruktiven Zusammenfassung 409 A6 Ausgelagerte Details der Theoriefolien 410
