Der Zusammenhang von technischer Entwicklung und gesellschaftlicher Modernisierung wird mit Mitteln der systemtheoretischen Soziologie untersucht. Zu diesem Zweck werden die Konzepte "Technik" und "soziale Evolution" reformuliert. "Technik" ist ein spezieller Typ der Grenzbildung von Systemen, die Ereignisse ihrer Umwelt als kausal verknüpft beobachten; Technik wird demnach definiert als fixierte Erwartung, die sich auf kausal verknüpfte Umweltereignisse bezieht. "Soziale Evolution" ist der Typ des Strukturwandels von sozialen Systemen, der sich aus der Selektion und Restabilisierung von Strukturvariationen ergibt. Aus soziologischer Sicht ist jede technische Entwicklung als ein spezifischer Aspekt der sozialen Evolution zu verstehen. Dies wird mit der Konfrontation des Begriff des "Fortschritts" mit dem der "Modernisierung" gezeigt. Eine Gesellschaft versucht durch das Verwenden und das Beschränken von Technik über ihre eigene Evolution zu verfügen. Es erweist sich, daß diese Versuche zwar komplexer, aber nicht unbedingt erfolgreicher werden. Die einer jeden Evolution eigene Entwicklungsoffenheit kann nicht außer Kraft gesetzt werden, auch dann nicht, wenn eine Gesellschaft Evolutionstheorien entwickelt und reflexiv auf sich selbst anwendet. Anders als vormoderne Gesellschaften zeichnet sich die moderne Gesellschaft durch ihre hochgradig frei kontextualisierbare und damit riskante Technik aus. Kontextualisierungen und Entscheidungsnotwendigkeiten im Umgang mit moderner Technik bedingen Reflexivität. Technische Entwicklungen lassen Determinationen und Optionen in gleichem Maße wachsen. Komplex ist die soziale Seite von Technik, nicht die Kompliziertheit ihrer technischen Komponenten. Reflexive Technologiepolitik und Technikfolgenabschätzung sind gezwungen, die soziale Dynamik technischer Entwicklungen zu berücksichtigen. / There are several means to analyse the intrinsic connection of technological development and social evolution in sociology today. The thesis examines technology and its development as part of social evolution from a system-theoretical point of view. Using this approach, terms like "technology" and "social evolution" are reformulated. "Technology" is a particular type of border of social systems, using the mode of causality in observing its environment; thus Technology is defined as the fixation of causal expectations. "Social evolution" is a social systems' structural change by the selection and reinforcement of variations, creating a singular history. In terms of sociology, any technological development is part of a wider developing social context. This is visualized by confronting the terms "progress" and "modernization"; both being concepts of sociology as well as of debates on technology and social development. By using technology, by giving way to innovation, and by limiting the use of technology, a given society tries to monitor and influence its own evolution. The thesis shows that these attempts become more complex, but not necessarily more effective. The fundamental properties of any evolution cannot be annulated --- the social evolution always remains unpredictable, even when evolutionary theories allow reflexive observations. In contrast to its predecessors the modern society constitutes a type of technology which is highly independent of any given social context. But this freedom is risky. Contextualizations and decision-makings imply a higher degree of reflexivity. In the case of technological development, both determinations and options increase at the same time. What is complex in technological development is its social, not its mere technical side. Any reflexive debate on technology has to reflect technology as a social issue.

Through interviews with copywriters, this essay examines how AI technologies may influence the creative process their work. We must also look at whether AI can be creative in order to provide an answer to the study topic. Therefor the paper explores the concept of creativity.The conclusion according to the study, shows that AI can be creative when collaborating with humans. For a copywriter, using AI streamlines and simplifies their process. The study also demonstrates that co-creativity, or human and AI collaboration in the creative process, is advantageous to both copywriters and AI.Furthermore, the study demonstrates that copywriters are not necessarily threatened by AI. Certain simple aspects of the process, such swiftly collecting and compiling data, can be replaced by AI systems. A collaboration primarily shows beneficial consequences for a copywriter. They have more time for creativity in their job process. Although most of the study's interviewees are supportive of a wider use of AI technologies in the media sector, there are concerns regarding AI's limited capacity for critical engagement with its own creations. It is also argued that AI lacks other crucial characteristics like warmth and soul, which are essentials aspects of creativity.

No. of bitstreams: 0 Previous issue date: 2009 / Esta pesquisa investiga como ocorre a gestão de porta-fólio dos projetos de inovação em uma Instituição Pública de Pesquisa em Saúde, ilustrada pelo caso das unidades de produção da Fiocruz. Utilizou-se na investigação elementos de análise propostos pela metodologia da Démarche Stratégic (gestão estratégica), que supõe a adaptação de um enfoque empresarial para o setor público de serviços em saúde. A avaliação estratégica dos projetos ocorre nas dimensões: valor (atratividade) dos projetos de P&D e posição concorrencial e calcada no modelo McKinsey, que leva em conta competências distintivas, interesses próprios e vontades da Instituição, sendo adequada à Fiocruz, que possui atividades interligadas e se defronta com possibilidades na escolha de oportunidades atuais ou novas (diversificação) aplicadas à saúde. Por ser um modelo que integra os conceitos de sinergia e barreiras à entrada, facilita opções estratégicas; contudo, o diagnóstico que o instrumento de análise aponta é muito mais relevante que definir estratégias específicas. Os resultados indicam a necessidade de considerar a incorporação de critérios adicionais no modelo qualitativo, tais como: regulação governamental de mercado, proteção patentária, vantagem de custo, capacidade gerencial e acesso privilegiado às matérias-primas. / This research investigates how does the management of the portfolio of innovation projects in an Institution of Public Health Research, illustrated by the case of the production units of Fiocruz. The research applied aspects of the analysis methodology proposed by the Démarche Strategic (strategic management), which imply the adaptation of a business approach to public sector health services. Projects of strategic analysis in accordance with the model of McKinsey, occurred in the dimensions of R & D projects value (attractiveness), and its competitive position, taking into account the different abilities, interests and desires of an institution such as the Fiocruz, whose activities are interconnected and has to choose opportunities that are current and diverse to be applied to health. The model that integrates the concepts of synergy and entry barriers, facilitates strategic options, however, the diagnosis that the instrument of analysis points is more important than specific strategies. The results indicate the need to consider the incorporation of additional criteria in the qualitative model, such as government regulation of the market, patent protection, cost advantage, management skills, and privileged access to raw materials.

Cette thèse a été effectuée sous le couvert d’une convention CIFRE issue d’une collaboration entre la Société Cryantal (Lognes, France) et les laboratoires universitaires C3S (EA 4660) et MOVE (EA 6314) de Franche-Comté et de Poitiers. Elle a été articulée autour du développement d’une nouvelle technologie de chambre de Cryothérapie Corps Entier (CCE). Le travail mené au cours de ces quatre années a eu pour objectifs : 1) L’identification des besoins technologiques et méthodologiques à partir d’études conduites sur le terrain et de l’analyse de la littérature scientifique ; 2) Le développement d’un prototype de chambre CCE à partir des besoins identifiés ; 3) La validation technologique du prototype en vue de son industrialisation ; 4) D’apporter des perspectives d’évolutions futures pour le développement du prototype afin qu’il devienne une chambre CEE commercialisable. Afin de répondre à ces objectifs, la thèse a été divisée en deux parties distinctes.La première partie met en évidence les applications pratiques et les besoins technologiques afin d’identifier les limites et avantages des différentes méthodes et techniques utilisées en vue du développement d’un nouveau prototype de chambre CCE. Les études conduites sur le terrain dans les conditions réelles de compétition ont montré que la CCE n’était pas vécue comme une contrainte importante par les athlètes et qu’elle leur permettait d’améliorer la qualité de leur sommeil perçu. Nous avons également montré que des individus avec un indice de masse corporel moins élevé supportaient moins bien les expositions au froid extrême en cabine comparé à ceux possédant un indice de masse corporel plus important. La revue de littérature scientifique a mis en évidence le manque crucial de données valides concernant les températures d’exposition dans les chambres et cabines. Elle pointe également pour la première fois, l’ensemble des protocoles d’expositions utilisés à ce jour dans les domaines d’applications relatifs aux pathologies traumatiques et de récupération physique. Elle crée le lien indispensable entre les différents domaines d’utilisation de la CCE et les différentes technologies utilisées.La seconde partie expose l’ensemble du développement technologique du prototype de la nouvelle chambre CCE, sa validation et son optimisation pour pouvoir prétendre à sa commercialisation. Elle comporte une étude scientifique de validation technologique du prototype de chambre de CCE basé sur la variation de la température cutanée des individus exposés. Les résultats ont montré que les variations de température cutanée engendrées par l’exposition avec la nouvelle technologie étaient similaires aux variations rapportées avec les autres technologies existantes. Les mesures préliminaires réalisées sur le prototype ont permis d’apporter des perspectives d’évolutions futures en vue de la commercialisation de la chambre. / This thesis has been completed as part of a CIFRE agreement between the research and development department of the Cryantal Company (Lognes, France) and the C3S (EA4660) and MOVE (EA6314) laboratories from the Universities of Franche-Comté and Poitiers. The aim of the thesis was the development of a new technology of whole-body Cryotherapy (WBC) chamber. The various studies that we conducted centred on : – the identification of technological and methodological requirements from field studies and the analysis of scientific literature; – the development of a WBC chamber prototype according to the identified requirements; – the technological validation of the prototype to its industrialization; and – the evolution of the prototype toward a marketable version. The thesis was divided into two parts. The first part highlights the practical applications and the technological requirements to identify the limits and the advantages of the existing methodologies and technologies in order to develop a new WBC chamber device. Studies performed in the field during competitions showed that WBC is well tolerated by athletes and can be used during heavy competition periods and/or during training periods. We also demonstrated that female athletes with lower body-mass indexes seem to be much more sensitive to cold than female athletes with higher body-mass indexes. The literature review reported a lack of data concerning the actual temperature inside the WBC chamber and cabin. The lack of methodological information for the exposure protocol was also pointed out. It creates the link between the field of application of the WBC and the different technology used. The second part presents the technological development of the new WBC chamber prototype, its validation, and its optimisation in order to be commercialized. This part includes a validation study of the prototype based on the effects of a 3-minute exposure on the skin temperature decrease of exposed individuals. The results showed a similar decrease to those observed with other WBC existing technologies. This is certainly due to the homogeneity of the temperature of exposure and the new technology developed. Preliminary measurements of the prototype allowed for the prospect of the commercialization of this new WBC chamber.

The purpose of this study was to investigate the challenges in teaching IsiXhosa home language in rural secondary schools. Learners from Grades 8 to 12 perform poorly in IsiXhosa grammar, essay writing, literature and oral work. The researcher sampled 40 learners from each of two senior secondary schools, eight parents and eight IsiXhosa subject specialists (two district based and six school based) to take part in the research. Data for this study were collected during cluster moderations in one of the secondary schools by using document analysis, interviews and questionnaires. Qualitative and quantitative methods were used by the researcher to analyse IsiXhosa results from Grade 8 to Grade 12. Analysis of documents such as mark schedules and marks for formal and informal tasks gave evidence that learners perform poorly in grammar, literature, oral work and essay writing. Scarcity or non-availability of distinctions (levels 6 and 7) in Grade 12 final exams as well as in Grades 8 to 11 proves that the language demands special attention for its teaching and learning in the secondary classroom situation; the conclusions were therefore drawn and recommendations made. / Curriculum and Instructional Studies / D.
