Aus der Einleitung: "Die Produktarchitektur ist ein Modell zur Abbildung der Verknüpfung zwischen funktionaler und physischer Sichtweise auf ein Produkt und Ausgangspunkt für eine Vielzahl von Methoden, u. a. zur Funktionsintegration oder Modularisierung. Die dabei adressierten Ziele der Produktentwicklung sind sehr unterschiedlich und fokussieren bspw. die Reduktion der Teilezahl und des Gesamtgewichts oder eine effiziente Variantenerzeugung durch Produktbaukästen. Der Lösungsraum bei der Produktarchitekturgestaltung wird maßgeblich durch bekannte und nutzbare Technologien und deren Restriktionen bestimmt. So geht die spanende Fertigung mit steigender geometrischer Komplexität der Bauteile oftmals mit einer erheblichen Kostensteigerung einher. Werkzeugerfordernde Fertigungstechnologien wie bspw. das Druckgießen sind in der Regel nur für größere Bauteilstückzahlen rentabel. Die Einführung additiver Fertigungsverfahren bietet neue Möglichkeiten zur Überwindung dieser Restriktionen und zur Realisierung zusätzlicher Freiheiten in Bezug auf die geometrische Gestaltung sowie Materialzusammensetzung bei der Produktarchitekturgestaltung. Während der Produktentwicklung werden die Potentiale additiver Fertigungsverfahren jedoch oft nicht umfassend berücksichtigt, wodurch besonders bei der Gestaltung der Produktarchitektur große Potentiale unerschlossen bleiben. Stattdessen erfolgt die Gestaltung der Produktarchitektur implizit und Möglichkeiten bspw. zur Funktionsintegration werden nur vereinzelt genutzt. Aus diesem Defizit leitet sich die zentrale Fragestellung dieses Beitrags ab: Wie können Potentiale additiver Fertigungsverfahren bei der Gestaltung der Produktarchitektur systematisch berücksichtigt werden? Zur Beantwortung dieser Frage wird in Abschnitt 2 die Produktarchitekturgestaltung in den Produktentwicklungsprozess eingeordnet und aufgezeigt, wie verschiedene Zielstellungen einer Produktentwicklung durch sie adressiert werden können. Technologische Einflüsse auf die Produktarchitekturgestaltung werden in Abschnitt 3 am Beispiel von additiven Fertigungstechnologien erläutert, bevor in Abschnitt 4 ein methodisches Rahmenwerk vorgestellt wird, welches die Nutzung von Potentialen additiver Fertigungsverfahren durch die Bereitstellung von Prinzipien unterstützt. Die Anwendung des Rahmenwerks wird in Abschnitt 5 am Beispiel eines adaptiven Drehgelenks für Parallelroboter verdeutlicht.

This cumulative dissertation consists of four papers that investigate retailer switching and identify potential and threat of cross-channel retail services (CCRS) for retail businesses. The first, conceptual paper compares different theories and models of retail quality. It derives the concept of retailer aspects as a framework to measure retailer quality and further discusses how CCRS can serve as a tool to enhance those retailer aspects. The second paper discusses results from a consumer panel survey and quantifies the influence of satisfaction with retailer aspects on retailer switching during webrooming behavior. The findings of this second paper present the two retailer aspects assurance of delivery and competitive product pricing as key determinants for retailer switching. The third paper defines CCRS and outlines a conceptual classification scheme for CCRS assessments – the CCRS Pentagon. The fourth paper quantifies the impact of CCRS adoption and retailer aspect preferences on CCRS-induced retailer switching based on a second consumer panel survey. Results from this second study affirm the existence of CCRS-induced retailer switching. The paper concludes that CCRS can serve as a retailer’s lock-in mechanism, but that the availability of CCRS in retail environments also threatens retail businesses. In sum, the dissertation provides academic contributions and suggestions for further academic research as well as practical implications and management tools for application in retail businesses.:I.

nÃo hà / Para se facilitar a aprendizagem cientÃfica, à preciso investigar a concepÃÃo de estratÃgias didÃticas alternativas, procurando-se estabelecer vinculaÃÃes entre o uso pedagÃgico do computador e o laboratÃrio de prÃticas cientÃficas, como ferramentas de apoio pedagÃgico ao desenvolvimento do processo de ensino-aprendizagem. A presente pesquisa focou a concepÃÃo de estratÃgias de ensino e aprendizagem, atravÃs da realizaÃÃo de sessÃes didÃticas, de quÃmica, articulando-se pedagogicamente os laboratÃrios de experimentaÃÃo cientÃfica e de informÃtica, para facilitar, junto aos alunos, a aprendizagem significativa de conhecimentos de quÃmica orgÃnica, especificamente a funÃÃo hidrocarbonetos. Aportou-se na teoria de aprendizagem significativa de Ausubel, nos mapas conceituais de Novak e na proposta construcionista de Valente. Realizou-se o uso do software educativo Jmol, enaltecendo-se a construÃÃo colaborativa de conhecimentos, competÃncias e habilidades. Tais aÃÃes foram realizadas com a participaÃÃo de onze alunos, do 3 ano do ensino mÃdio de uma escola pÃblica do municÃpio de Beberibe, concebidas em quatro etapas: preliminar, teÃricoexperimental, prÃtico-virtual e colaborativa. A abordagem metodolÃgica da pesquisa foi do tipo qualitativa e se caracterizou como pesquisa exploratÃria. Os dados obtidos por meio dos questionÃrios, e as observaÃÃes do professor-pesquisador permitiram analisar e concluir haver indÃcios de desenvolvimento da capacidade criativa, colaborativa, que os alunos se motivaram para desenvolver novas habilidades e construir novos conhecimentos, atravÃs da realizaÃÃo pedagÃgica da prÃtica de experimentaÃÃo de quÃmica orgÃnica e utilizaÃÃo do software Jmol. O experimento da produÃÃo de etino na etapa teÃrico-experimental foi uma maneira de trabalhar de forma mais clara, dinÃmica e colaborativa a ressignificaÃÃo e construÃÃo de conhecimentos. O uso pedagÃgico e colaborativo do software Jmol na etapa prÃtico-virtual e de mapa conceitual na etapa colaborativa, possibilitaram aos alunos desenvolver uma compreensÃo mais facilitadora do conceito, escrita, representaÃÃo e visualizaÃÃo em trÃs dimensÃes de compostos da funÃÃo hidrocarbonetos. / To facilitate the science learning, you need to investigate the design of didactic strategies alternatives, and seeking to establish linkages between the pedagogical use of the computer and the laboratory of scientific practices, such as tools of pedagogical support for the development of the teaching-learning process. The present research focused on the design of strategies for teaching and learning, through the completion of didactic sessions, of chemistry, articulating it is pedagogically the laboratories of scientific experimentation and computer, to facilitate, together with the students, the significant learning of the knowledge of organic chemistry, specifically the light hydrocarbons. Disembarked on the theory that meaningful learning of Ausubel, the conceptual map of Novak and the proposal of constructionist Valente. There was the use of educational software Jmol, praising the collaborative construction of knowledge, skills and abilities. Such actions were carried out with the participation of 11 students, of the 3rd year of secondary education in a public school in the municipality of Beberibe, designed in four stages: preliminary, theoretical and experimental, practical-virtual and collaborative. The methodological approach of the research was qualitative and is characterized as exploratory research. The data obtained by the use of questionnaires, and observations of the teacher-researcher allowed to analyze and conclude there is evidence of the development of creative ability, collaborative, which the students are motivated to develop new skills and build new knowledge through the realization of pedagogical practice of experimentation of organic chemistry and use of software Jmol. The experiment of the production of ethno in step theoretical-experimental was a way of working in a more clear, dynamic and collaborative signification and construction of knowledge. The use of pedagogical and collaborative software Jmol in the stage-practical virtual and conceptual map in the stage collaborative enabled students to develop an understanding more facilitator of the concept, writing, representation and visualization in three dimensions of compounds of light hydrocarbons.
