This exploratory case study was undertaken to obtain a greater understanding of the difficulties that physics students face when solving image-object projections in optics problems. This was carried out by studying the students’ reasoning when facing new kinds of problem settings using the refraction of light and the position of the virtual image and the real object as the frame for the research. The results show that there is more than one reasoning possibility that is feasible for students to use when dealing with the same problem. The results also illustrate how several different ways of reasoning may be simultaneously needed to solve a refraction problem. The different kinds of reasoning have been referred to as reasoning categories in this study. The analysis illustrates how the categories complement each other, and the use of many reasoning categories is shown to be fruitful. However, the vast majority of the participants made contradicting answer selections when solving similar problems by using contradicting reasoning approaches. This lack of consistency in the participants’ reasoning could indicate that they have a fragmentary understanding of optics in general. Both the capability to link reasoning approaches together, as well as the affordances that different modes of representations offer, are needed for the construction of a better conceptual understanding. Only mastering a few ways of reasoning and a few modes of representation could lead to fragmented knowledge, which, in turn leads to making problem solving really challenging. One purpose of this study was to find out if reasoning categories and modes of representations are essentially linked. If so, then the reasoning categories would be determined by the representation of the problem. The analysis shows that there is a connection, but that there are also other factors at play.

Like many industries, the nuclear power industry in Sweden is currently facing the challenges of a major generational change. To meet these challenges, alongside the demands for a high level of security, the industry has attempted to standardise its mode of operations as far as possible. Apart from various technological fixes and safety devices, manuals and instructions have been modelled for every conceivable situation, or course of events; documentations and formal systems of co-ordination that become larger and larger, and more and more detailed. In high-risk industries there is a tendency to equate learning with changes in external patterns of behaviour, as against fixed standards, typically among operating staff. The acquisition  of professional skill, on the other hand, is the result of participation in practice. From this point of view, rather, learning is the outcome of reflection, upon actual events and experiences. Recurrent training can be used to promote formalisation, but also to explore and reinforce the experience based knowledge of skilled operators; between these approaches, the former prevails. Accidents and incidents incessantly put in question what is commonly referred to as the safety culture of various power plants, and subsequent to the misfortunes at Forsmark 1 in 2006, the accident was described as the culmination of a longterm decline in safety culture. The strong requirement for security and control is a cause of formalisation, whereas the need to support reflection as formation of professional skill tends to be omitted. Even so, experience based skill and knowledge remains a substantial consituent of what could be regarded as a dependable safety culture. Codified knowledge must be interpreted and applied in practice. Furthermore, experienced professionals, from encountering a great variety of situations, seem to develop what can be described as the skill of anticipation, and, as shown in connection with the incident at Forsmark 1, an ability to handle the unexpected. The urge for formalisation raises certain concerns: that of the primacy of defining the containments of professional skill, the impact and resilience of local knowledge and diversity, and the hollowing out of ability and skill within work-life organisations. The “human factor”, that is the operating staff, is commonly made responsible for established accidents and incidents. Even so, experienced personnel are able to manage a variety of unforeseen events and disturbances, that sometimes occur in high-risk technology industries. At times, on the contrary, the human factor saves technology, instead of the other way around. This study explores the concept of safety culture within the nuclear power industry from an epistemological perspective. It discusses the use of recurrent training, and the role of experience based skill and knowledge in the operating of Swedish power plants. What methods can be employed to support experience based knowledge as an essential complement to standardised work processes, codified knowledge, or benchmark strategies? Principles of formalisation need to be supplemented with a more thorough exploration of professional skill, in which a distinction between behaviour and responsibility can be made. / QC 20110906

La triade de Vitruve revisitée à travers l’exemple de l’architecture d’Hervé Tordjman. La place de l’art et de la technique dans le processus de conception. Aujourd’hui, la conception de l’architecture demeure comme à son origine, dépendante de l’interaction des trois qualités indissociables de Vitruve : firmitas, utilitas et venustas, considérées autrefois indispensables à l’acte de concevoir. L’incarnation de cette triade dans le processus créatif des concepteurs contemporains que nous avons étudiés dans le cadre de cette thèse, qu’ils soient architectes-ingénieurs-artistes, architectes-artistes ou architectes-ingénieurs, est assujettie d’une part, aux mécanismes cognitifs : le modèle et la pensée analogique ; et d’autre part aux compétences et postures de chacun.Toutefois, en dépit de ce caractère personnel du processus conceptuel, ces trois qualités qui jadis devaient être articulées par une seule personne (l’architecte), se trouvent aujourd’hui menées à l’unisson selon un processus collectif.En effet, grâce aux nouvelles technologies numériques actuelles, l’architecte et les ingénieurs sont mobilisés dans un processus dit collaboratif abolissant ainsi les frontières entre « parti » architectural et « idée constructive », architecture et construction. A travers l’analyse de l’œuvre de l’architecte parisien Hervé Tordjman (1975), il faut souligner l’importance qu’acquiert la « firmitas » dans le processus de création en s’intégrant harmonieusement avec les autres composantes (utilitas et venustas). Ainsi, le point de vue de l’auteur et de chaque acteur de la chaine de conception devient partie intégrante dans le processus. Une telle articulation collective de la trinité vitruvienne dans la pratique contemporaine du projet marque une évolution dans la façon de concevoir l’acte architectural et non une rupture. / Vitruvian triad revisited through the example of the architecture of Hervé Tordjman. The place of art and technique in the design process. Today, the design of architecture remains as to its origin, dependent on the interaction of three inseparable qualities stated by Vitruvius: firmitas, utilitas and venustas, once considered essential to the act of conceiving. The embodiment of this triad in the creative process of contemporary designers that is the concern of this thesis, both artists-architects-engineers, architects or artists-architects-engineers, is subject on the one hand, to cognitive mechanisms: the model and analogical thinking; and secondly to individual skills and postures.However, despite this personal character of the design process, these three qualities which once had to be articulated by one person (i.e. the architect), are now conducted in unison as a collective process.Indeed, thanks to new existing digital technologies, the architect and engineers are mobilized in a process said collaborative that abolishes the boundaries between the architectural part and the constructive system that is architecture and construction. Through the analysis of the work of the Parisian architect Hervé Tordjman (1975), we must emphasize the importance acquired by the "firmitas" in the creation process by being harmoniously integrated with other components (utilitas and venustas). Thus, the author’s view as well as that of each player in the design chain becomes part in the process. Such a collective articulation of the Vitruvian trinity in the contemporary practice project marks an evolution in how to design the architectural act, not a rupture.

That is, it is not a research that works pautada in the untiring quarrel if the photograph shows to the real or a trace of the real, this is a philosophical and semiótic bias, however to this research it more mentions this problematic one as part of the passage of the history of the carried through studies already until today with the photographic image, moreover this is a quarrel that already very was incited in the half academics and for the enthusiastic ones of the subject. The studies had been directed more for the credibility of the ampler point of view as for the individuals in general, the laypeople, fans of the photograph, to the readers of periodicals and magazines, at last, the people in a general way. After the digital technology doubts on the credibility in the photographic image they had started to hang in air, for the fact of that previously the people did not give account that the photographs could be modified, that the photograph is a process that always was modified, that already it was born manipulated for being chemical a physical process. The research walks to the side of sociology, therefore it was with the technological evolution that these questions had come to up, the individuals had started to buy cameras in very bigger number of what they bought has 30 years behind, the majority of the people has a compact cameras, cameras in the cellular ones, as well as almost everybody has access the internet and see transmitted images being of a side for the other, interacting of this form intensely. Today we live a imagétic society. In way that the photographic image is losing force in what its credibility says respect. One searched diverse sorts of representation of the photograph; journalism, authorial, conceptual and advertising, since its analogical production until our days with the imagétic profusion of the digial age and in each photographic language the research in shows different behavior to them with respect to credibility in the respective photographic productions / O estudo procura elucidar a questão da credibilidade da imagem fotográfica depois que surgiram aparelhos fotográficos mais avançados em tecnologia e em precisão de imagem. Não é uma pesquisa pautada pela discussão se a fotografia mostra o real ou um traço do real. Esta pesquisa menciona tal questão, porém mais como parte do percurso da história dos estudos já realizados até hoje com a imagem fotográfica, mesmo porque essa é uma discussão que já estaria muito acirrada nos meios acadêmicos e entre os entusiastas do assunto. Os estudos direcionaram-se mais para a credibilidade do ponto de vista mais amplo no que se refere aos indivíduos em geral, os leigos, amadores da fotografia, aos leitores de jornais e revistas, enfim, às pessoas em geral. Depois da tecnologia digital, dúvidas sobre a credibilidade da imagem fotográfica começaram a pairar no ar, pelo fato de que as pessoas anteriormente não se davam conta de que as fotografias pudessem ser alteradas, que a fotografia era um processo que sempre fora alterado, que já nasceu manipulada por ser um processo físico/químico. A pesquisa caminha ao lado da socioeconomia, pois foi com a evolução tecnológica que essas questões vieram à tona, os indivíduos começaram a comprar câmeras em número muito maior do que compravam há trinta anos, inúmeras pessoas possuem câmeras compactas, câmeras nos celulares, assim como quase todo mundo acessa a internet e veem imagens sendo transmitidas simultaneamente em vários lugares interagindo intensamente. Hoje vivemos uma sociedade imagética. A imagem fotográfica está perdendo força no que diz respeito à sua credibilidade.Pesquisaram-se diversos gêneros de representação da fotografia; jornalística, amadora, autoral, conceitual e publicitária, desde sua produção analógica até os nossos dias com a profusão imagética da era digital. Em cada linguagem fotográfica a pesquisa revela diferentes comportamentos no que se refere à credibilidade das produções fotográficas de quem está atrás da câmera

En 2666, novela póstuma del escritor chileno Roberto Bolaño, asistimos a la representación del mal y la violencia a través de un discurso narrativo que se caracteriza por la fragmentación, la liminariedad y la hipertextualidad.  El objetivo de nuestro trabajo es estudiar el uso de la anamorfosis como procedimiento deformatorio que oculta claves de la novela, y el carácter oblicuo de la violencia narrativa.  Para ello adoptamos como metodología de análisis la hermenéutica analógica del filósofo mexicano Mauricio Beuchot, ya que nos brinda un modelo que nos permite estudiar cómo opera el procedimiento de la anamorfosis en la representación de la violencia narrativa, develando las relaciones analógica intratextuales e hipertextuales, y así la dimensión simbólico-icónica de la novela.  También nos hacemos cargo de los conceptos de liminariedad del antropólogo británico Victor Turner y de ritos de paso del etnólogo y antropólogo francés Arnold van Gennep, y del concepto de hipertextualidad del narratólogo francés Gérard Genette.

Le présent manuscrit développe une problématique liée à l’implication des capacités de gestion de buts et d’engagement des fonctions exécutives dans le raisonnement par analogie et son développement. Les trois premières expériences étudient cette problématique dans deux tâches de raisonnement par analogie différentes à travers l’étude des stratégies visuelles employées par des adultes et des enfants de 6-7 ans. Les résultats montrent des différences de stratégies visuelles entre les tâches, liées aux buts différents de celles-ci, ainsi que, entre enfants et adultes, des différences de patterns visuels liés à l’inhibition de l'information non pertinente pour la résolution des problèmes. Les deux expériences suivantes étudient les stratégies visuelles, toujours en lien avec le fonctionnement exécutif et le maintien du but, dans une tâche A:B::C:? dont la difficulté est manipulée afin de mettre en évidence des différences d’engagement de processus de contrôle et d’évaluation. Les résultats montrent un effet de la difficulté des essais, ainsi que du type de distracteur, dans les stratégies visuelles. Enfin les trois dernières expériences étudient l’implication de la flexibilité cognitive, une des fonctions exécutives, dans le raisonnement par analogie, chez l’enfant (5-6 ans), limité dans sa flexibilité. Les résultats montrent que l’ancrage dans un type de représentation, pertinent ou non pour la solution du problème, est lié à leur capacité à résoudre le problème, et suggèrent une difficulté à changer de représentation au cours de la résolution. Ces résultats sont finalement discutés en rapport aux modèles de raisonnement par analogie et de développement de cette capacité. / This manuscript develops an issue related to the involvement of goal management capabilities and executive functions in this type of reasoning and its development. The first three experiments examine this issue in two tasks of analogical reasoning, the scene analogy task and the A:B::C:? task, through the study of visual strategies used by adults, and children aged 6-to-7. The results show differences in visual patterns related to goals, and to the inhibition of irrelevant information for the solution of the problems, between the different tasks, and between children and adults. The following two experiments study the visual strategies, always in relation to executive functioning and goal management, in an A:B::C:? task whose difficulty is manipulated to highlight the difference in involvement of monitoring and evaluation processes. The results do show an effect of the difficulty of the test and the type of distractor in the visual strategies employed. Finally, the last three experiments investigate the involvement of cognitive flexibility, one of the executive functions, in the analogical reasoning of preschool children (5-6-year-olds), limited in their flexibility. The results show that their early anchoring in a type of representation, relevant or not to the solution of the problem, is related to their ability to solve the problem later, and thus suggest a difficulty in shifting their representation during the resolution of the problems. These results are finally discussed in relation to models of analogical reasoning and of the development of this ability, especially those integrating goal management and executive functions.

Following established traditions in anthropology and sociology, where cross-border research helps to identify important themes which benefit from comparative study, this dissertation introduces cross-sector policy research as a new methodology for generating useful insights about public policy. The cross-sector method is applied to the study of the UK energy and transport sectors. A range of generic policy developments in the energy sector are identified including: the development of efficiency indicators, scenario analysis, and the establishment of energy efficiency programmes. Such developments have not, as yet, occurred in the transport sector. A structural analogy between energy and transport is developed which is used to generate a range of innovations for transport policy including: gross mass movements and intensities as indicators of the efficiency with which the economy uses transport; the projection of a quantitative scenario of sustainable mobility; and the outline of a transport efficiency programme. The insights from the analogy are generalised to consider the benefits of a wider application of cross-sector policy research to other policy areas.

Many people face difficulties in remembering knowledge, which is complex and abstract. This is especially important when the descriptions of knowledge are to be stored in searchable knowledge bases. But if complex knowledge can be transferred through real life stories, it is more understandable and easier to retrieve for the knowledge acceptor. Moreover, if the stories follow a certain pattern like ‘intentional suspense’ it may be more useful. This study investigates how far a story with intentional interruption is helpful in transferring complex computer science knowledge through processing of information that compares similarities between new and well-understood concepts. The data collection was done by applying framework analysis approach through the interview of 40 students of Stockholm University. Results of this study is assumed to help organizations to design, store and retrieve complex knowledge structures in knowledge bases by using a specific pattern of the stories used in the narrative pedagogy known as 'Zeigarnik effect' which is a form of creating suspense. Interviews with managers showed that they are positive to using the type of knowledge transfer as is proposed in the results of this thesis. Transcribed interviews with students show that the students appreciate and understand the use of analogies in combination with the ‘Zeigarnik effect’ as is described in the result of this thesis. After analysis of the data collected from the experiments, it was confirmed that ‘Zeigarnik effect’ has a small positive effect for a group of people as better results have been found in most of the time when ‘Zeigarnik effect’ was used as compared to when the ‘Zeigarnik effect’ was not used. The participants that experienced the ‘Zeigarnik effect’ answered in a better way which proved that their understanding and memory regarding the subject have been enhanced using it.

Zeit ist ein fundamentaler Aspekt menschlichen Verhaltens. Während Untersuchungen bislang meist nur auf einem der drei Hauptaspekte der Zeit: Dauer, Zeitfolge und individuelle zeitliche Orientierung fokussierten, untersucht diese Dissertation Zusammenhänge zwischen der individuellen zeitlichen Orientierung und der Zeitfolge. Zeit ist nicht direkt wahrnehmbar, sondern an kognitive Abstraktionsprozesse gebunden. Diese benötigen kognitive Ressourcen und werden kognitiven Fähigkeiten beeinflusst. Daher wurden Zusammenhänge zwischen individueller zeitlicher Orientierung und allgemeinen kognitiven Fähigkeiten ebenfalls untersucht. Studie 1 analysiert, wie verschiedene Aspekte individueller zeitlicher Orientierung korreliert sind, und diese Korrelationen von Alter und Geschlecht beeinflusst sind. Studien 2 und 3a analysieren Zusammenhänge zwischen individueller zeitlicher Orientierung und der Zeitfolge. Studie 3b untersucht mittels einer geometrischen Analogieanforderung Korrelationen zwischen individueller zeitlicher Orientierung und höheren fluiden Intelligenzleistungen. Befunde zu Zeitperspektive-Chronotyp- Relationen sowie Zeithorizont-Chronotyp-Relationen werden berichtet, ebenso Zusammenhänge zwischen Zeitperspektive, Zeithorizont und der Zeitfolge. Ausgehend von diesen und früheren Befunden wird ein kognitives Modell vorgestellt, welches alle drei Aspekte psychologischer Zeit (Zeitdauer; Zeitfolge; individuelle zeitliche Orientierung) integriert. Ferner werden als Ergebnis der Studien Zusammenhänge zwischen der Zukunftsperspektive und fluider Intelligenz sowie Chronotyp und verbaler Intelligenz berichtet. Verhaltensdaten und psychophysiologische Daten (Pupillendilation) zeigen ferner Zusammenhänge zwischen individueller zeitlicher Orientierung, analogem Denken, exekutiven Funktionen und Konfliktverarbeitung. So scheinen Zukunftsperspektive und Morgentyp eng mit Konfliktverarbeitung verbunden, der Zeithorizont hingegen eng mit inhibierenden Kontrollprozessen. / Time is a fundamental aspect of human experience. Whilst most research investigated major aspects of psychological time - time duration, time succession, individual temporal orientation - in isolation, this dissertation investigates interrelations between individual temporal orientation and time succession. Since psychological time is bound to cognitive abstraction processes that rely on cognitive resources and functions, interrelations between individual temporal orientation and cognitive capacities were also investigated. Study 1 explored how different levels of individuals’ temporal orientation may be interrelated, and how interrelations may be influenced by age and sex. Interrelations between individual temporal orientation and time succession were explored in a task predominantly requiring crystallized intelligence (Study 2) and in a semantic analogy task requiring crystallized and fluid intelligence (Study 3a). Study 3b investigated interrelations between individual temporal orientation and higher-level fluid intelligence measures by applying a geometric analogy task. Interrelations between time perspective and chronotype as well as between chronotype and temporal depth are reported. Further, both future time perspective and temporal depth are interrelated with time succession. A testable global working memory model of time perception integrating all three aspects of psychological time is proposed. Further, interrelations between individual temporal orientation and cognitive capacities are reported. Future time perspective was related to fluid intelligence, chronotype to verbal intelligence. Behavioral as well as pupillary data suggest that individual temporal orientation is related to analogical reasoning, executive functions and goal management. Whereas future time perspective and morningness appear interrelated with conflict detection, temporal depth appears interrelated with inhibitory control.
