Rozprawy doktorskie na temat „Experiment”

The diploma thesis deals with analysis of risks in relation to various focus (or types) of economic experiments. On the basis of background research suggests entirely new classification of economic experiments and subsequently examines general structure of economic experiment. Performed analysis then identifies major risks of experimental economics, analyses them and proposes possible countermeasures. Outputs of the work substantially enrich and extend current theory. Their utilization is expected in theory and practice, for purpose of scientific research or specific objectives of companies and institutions.

This thesis investigates the injunction to experiment in the social sciences and, more specifically, geography. This is both a geography of certain ways of thinking experiment, and an exploration of how particular strands of geographical thinking are being re-imagined and reworked as experimental under the influence of ideas and practices from within and beyond the discipline. Against the backdrop of recent debates about the status of experiment, it poses a number of key questions about what it means to be experimental, how experimental practices emerge and travel, and how these processes are inflected by the organization and atmospheres of particular sites of experimentation. These questions are addressed through a form of attentive participation at four key sites: The SenseLab and the Topological Media Lab in Montreal, the Institut für Raumexperimente in Berlin, and FoAM in Brussels. Based upon these encounters, and drawing upon the work of a range of exemplary experimentalists, the thesis develops the argument that there are new spaces of experiment which are worthy of such examination as part of a renewal of experimentation within geographical thinking. As such, the thesis outlines the logics of these forms of experiment and proposes the notion of ecologies of experiment. It also speculates on the possibilities for re-imagining what constitutes a geographical experiment, foregrounding the necessity of reactivating experiment as an ongoing ethos that needs careful cultivation and tending.

Syftet med denna studie är att redogöra hur förskollärare ser på och använder sig av naturvetenskapliga experiment i förskolan. Studien ska ta fram vilka motiv och målsättningar en förskollärare har inför en aktivitet med experiment. Tidigare forskning visar att naturvetenskap och teknik inte varit så högt prioriterade i förskolans pedagogiska verksamhet. Därför så reviderade Skolverket Läroplanen för förskolan 2010, då bl.a. naturvetenskap och teknik fick ett större utrymme i den pedagogiska verksamheten. För att introducera naturvetenskap på ett stimulerande och roligt sätt så undersöker jag om experiment kan vara ett bra pedagogiskt verktyg. I denna studie har jag gjort kvalitativa intervjuer med sju olika förskollärare. Jag besökte fem olika förskolor, varav två är belägna i storstad och tre i ett mindre samhälle. Förskolorna drivs med olika profiler som Montessori, Reggio Emilia, kristen och teknik. Studien utgår från arbetet med experiment i den pedagogiska verksamheten med hjälp av John Dewey och Lev S Vygotskij. Resultatet av studien visade att arbetet med experiment i förskolans verksamhet uppfylldes genom att barnen fick en lustfylld erfarenhet av naturvetenskapliga experiment. Att få arbeta med att undersöka, upptäcka och utforska nya fenomen genom experiment tycker respondenterna är viktigt. Respondenterna försökte i största mån att göra experiment utifrån barnens intresse och upptäckarlust.

Syftet med detta utvecklingsprojekt är att stärka naturvetenskapens roll i grundskolans tidigare åldrar. Att väcka intresse och lust för de naturvetenskapliga ämnena samt för att arbeta praktiskt så att eleverna är delaktiga i undervisningen. Det handlar även om att bekanta sig med naturvetenskapen i vardagen och inse att den är enkel att arbeta med. Materialet består av experiment som eleverna får och lärarhandledningar som följer med varje experiment till lärarna. Materialet är konstruerat till elever och lärare i årskurs 1-3 i grundskolan. Varje experiment har ett mål som ska nås från kursplanerna i naturvetenskap (biologi, fysik och kemi) för år 1-3 och där kan läraren bestämma hur/om eleverna har nått det målet. Lärarhandledningarna är uppbyggda med ”tips innan experimentet”, ”förklaring”, ”resultat”, ”undersök mer” och centralt innehåll”. För att utvärdera materialet fick två lärare i naturvetenskap titta på materialet och säga vad de tyckte om det. Upplevelsen av lärarnas tänkande kring arbetet var väldigt positivt och målet för att arbetet skulle vara lättillgängligt nåddes. En av lärarna skrev ”Du kommer säkert att locka många elever till större och vidare nyfikenhet med ditt material”. Lärarna ville gärna använda materialet och behålla det och det ses som något positivt. Möjlighet till skapande och elevernas intresse tas omhand och detta är förhoppningsvis bara början till att naturvetenskapen lyfts och används mer i skolan.
The purpose of this development is to strengthen scientific role in schools earlier ages. To arouse interest and desire for the natural sciences, as well as to work so that students are involved in teaching. It is also about to become acquainted with natural sciences in everyday life, and realize that it is easy to work with. The material consists of experiments that students and a teacher's guide as follows with each experiment to teachers. The material is designed to students and teachers in grade 1-3 in primary school. Each experiment has a target to be reached from the curriculum in science for years 1-3 and where trainer can determine how/if pupils have reached the goal. A teacher's guide is built with "tips before the experiment", "Explanation", "results", "explore more" and central content". In order to evaluate the material had two teachers in science look at the material and say what they thought about it. Experience of teachers' thinking around the work was very positive and the objective of the work would be accessible was reached. One of the teachers wrote "You will certainly attract many students to larger and further curiosity with your material". Teachers wanted to use the material and keep it and it is seen as something positive. An opportunity for the creation and students' interest will be looked after and this is hopefully just the beginning of that life sciences lifts and is used more in the school.

Humans are curious beings. We investigate and explore. We experiment and learn from them. But that process of learning is not very easy to study. Each person learns in different ways. The verbal part of learning is just one piece of the puzzle. The process of learning happens in many other ways, which makes is hard to study (especially in the past). The aim for this thesis is to examine whether experiment could be a tool to use in that research. It also aims to see if cultural transmission theory could be a theoretical base to study learning processes. The thesis describes experiments as a method, the relations between theoretical and practical memory and how culture is usually transmitted. It also studies two examples of experiments that were carried out in order to study learning. The thesis discusses the result of the experiments separately and in connection to cultural transmission theory. It discusses the possibilities of experiments as a method and its relation to the process of learning. It also discusses the relevance of modern novices.
Människan är en nyfiken varelse. Hon undersöker saker, prövar sig fram och lär sig av sina experiment. Något som bidrar till att vi dominerar planeten är att vi inte behåller kunskapen för oss själva, utan delar med oss. Detta inkluderar allt från sociala regler till redskapsrelaterade färdigheter och andra saker vi behöver för att klara oss. Inlärning är en process som sker på mer än det verbala planet, vilket gör det till ett svårstuderat ämne. Det blir ännu svårare i forntiden. Uppsatsen syftar till att undersöka om experiment skulle kunna vara ett verktyg för att studera den här inlärningsprocessen. Den syftar också till att se om kulturell transmissionsteori skulle kunna utgöra en teoretisk grund för dessa studier. Två experiment med fokus på inlärning används för att utvidga diskussionen. Uppsatsen utgår från följande frågeställningar: Hur kan experiment bidra till att förstå läroprocesser? Kan kulturell transmissionsteori vara en teoretisk grund för att förstå läroprocesser? Uppsatsen inleder med att redogöra för kulturell transmissionsteori. Teorin, som kretsar kring överföring av kulturell information till nästa generation, förklaras. Uppsatsen redogör för de grundläggande dragen, dess grundkomponenter samt vad som kan gå fel under överföringen. Den tar även upp den mer evolutionistiskt betonade inriktningen i teoribildningen kring hantverk, vilken brukar kallas för darwinism. Uppsatsen går sedan över till att fokusera på hur minnet fungerar, både på ett teoretiskt plan men även ett kroppsligt. Därefter beskrivs faktorer i inlärningssituationen som kan påverka resultatet, däribland hur undervisningen går till och vad situationen behöver för att fungera. Uppsatsen förklarar även experimentell arkeologi och hur detta kan appliceras i fallet inlärning. Även Chaîne Opératoire nämns. Därefter ges en övergripande beskrivning av de två exempel som uppsatsen använder sig av. Det ena exemplet innefattar mer än ett experimenttillfälle och med olika undervisningsmetoder. Dess nybörjarexperiment beskrivs sedan i detalj vad gäller utförande, resultat och de undervisningsmetoder hon använder sig av. Uppsatsen övergår sedan till att diskutera resultaten från experimentstudierna och vad man kan notera i det fysiska material som blev resultatet av experimenten. Det fysiska resultatet, alltså föremålen som experimenten resulterade i, sätts i relation till undervisningsmetod, know-how samt hur hög grad fel som uppstod. Resultatet pekar på att en aktivt engagerad lärare lyckas bäst med sin informationsöverföring. Därefter diskuteras hur pass relevant en modern novis egentligen är. Frågor om erfarenhet och djupare förståelse av fyndmaterialet lyfts samt frågan om exakta återgivningar. Därefter diskuterar uppsatsen Chaîne Opératoire, inlärning och kulturell transmission i relation till resultatet från experimenten. Chaîne Opératoire föreslås som ett möjligt sätt att strukturera och identifiera de olika stegen i den tillverkningsprocess som ett experiment går igenom. Begreppet diskuteras också som en teoretisk bas för att studera utvecklingen av know-how hos en elev, vilket bygger på att det finns material från en erfaren individ. Kulturell transmissionsteori diskuteras sedan som en ytterligare teoretisk grund i relation till inlärning och hur olika variationer mellan dess grundkomponenter skulle kunna användas i relation till studier av inlärning. Uppsatsen resonerar kring en kombination av experiment, Chaîne Opératoire och kulturell transmissionsteori som en möjlig teoretisk grund för ett ramverk som inkluderar kroppsliga som teoretiska aspekter samt som en möjlighet till att genom att utforska olika variationer av dessa eftersträva ett fysiskt resultat som är jämförbart med ett arkeologiskt material.

A mecânica quântica é uma das áreas da Física que surgiu em meados de 1900 e permanece em desenvolvimento até os dias atuais. Diversos aparatos tecnológicos são consequência deste importante ramo da Física que também contribui com a Medicina, Matemática, Filosofia, Literatura e Biologia. Logo, é imprescindível que o contato com esta ciência ocorra no contexto do ensino médio. Para inserir o estudante no mundo da mecânica quântica, isto é, na física do infinitamente pequeno, o aluno deve abandonar o pensamento clássico e pensar em termos do comportamento quântico e do indeterminismo no processo de medida, isto é, desenvolver a capacidade de abstração. Sendo este, o objetivo deste trabalho. Para tanto, foi escolhido o experimento da dupla fenda que permite trabalhar com a dualidade onda-partícula do elétron e do fóton. Por meio deste experimento, o aluno pode ser inserido paulatinamente numa trajetória rumo a descrição quântica necessária para o exame dos fenômenos subatômicos. A análise experimental é cuidadosamente realizada com o auxílio de laboratórios virtuais, disponibilizados gratuitamente em sítios eletrônicos, os quais representam um recurso que permite realizar procedimentos experimentais que necessitariam de grande aparato laboratorial. O experimento da dupla fenda é analisado em três etapas, relatadas a seguir: (i) a dupla fenda com partículas clássicas; (ii) a dupla fenda com ondas clássicas e; (iii) a dupla fenda com objetos quânticos como elétrons e fótons. O objetivo é demonstrar o comportamento dual do elétron. Posteriormente, para concluir de forma precisa e justificar o comportamento quântico do elétron é apresentado o princípio da indeterminação de Heisenberg e suas implicações filosóficas. Sendo assim, o objetivo central desta pesquisa é buscar integrar o comportamento quântico, que acontece na escala atômica, principalmente no contexto do ensino médio. Algumas orientações sobre como aplicar este trabalho em outros níveis de ensino aparecem no decorrer do texto e nos apêndices. Apresentando o comportamento dual, onda–partícula, do elétron, a interpretação probabilística e o princípio de incerteza. Acreditamos que o aluno será capaz de compreender um grande número de fenômenos que acontece em escalas que não são do domínio da mecânica clássica quando, em contato com estes temas. Este tema faz parte do conteúdo de física moderna contemporânea que vem sendo abordado em livros textos e vestibulares. Além disso, algumas das novas tecnologias utilizam a física quântica, desde microscópios eletrônicos, nanotecnologia, computação quântica, semicondutores, diodos (incluindo o LED), transistores, computadores, tablets, GPS, satélites, radares, aviões, lasers, scanners de código de barras, sistemas militares de defesa, CD e Blu-Ray players, criptografia, células fotoelétricas, sensores diversos, basicamente, tudo que é eletrônico. Um dos objetivos do trabalho é verificar quais os conhecimentos prévios o corpo discente possui, antes do contato com o conteúdo de física quântica, ou seja, o que faz parte do senso comum sobre este tema. Além disso, pretendemos verificar se o aluno consegue: i) distinguir, no final da aplicação desta pesquisa, que as leis da física em escalas atômicas são diferentes das leis da física clássica, ii) a importância da mecânica quântica na tecnologia e na sociedade.
Quantum mechanics is one of the areas of physics that emerged in mid-1900 and remains in development to the current day. Several technological devices are a result of this important branch of physics that also helps to Medicine, Mathematics, Philosophy, Literature and Biology. Therefore, it is essential that contact with this science occurs at the high school level, what actually occurs in a limited way, when it happens. To place the student in the world of quantum mechanics, that is, the infinitely small of physics, the student must leave the classical thought and think in terms of the quantum behavior and indeterminacy in the measurement process, namely to develop the capacity for abstraction. This is accurately the aim of this work. Thus, the double-slit experiment that lets you work with the wave-particle duality of the electron and the photon was chosen. Through this experiment, students can be gradually inserted on a path toward quantum description necessary for the examination of subatomic phenomena. The experimental analysis is carefully performed with the aid of virtual laboratories, available for free in electronic sites, which represent a resource to perform experimental procedures that would require large laboratory apparatus. The double slit experiment is analyzed in the following three steps, reported: (i) the slit paired with classical particles; (ii) the double slit and with classical waves; (iii) the double slit with quantum objects such as electrons and photons. The goal is to demonstrate the electron dual behavior. Later to complete accurately and justify the electron quantum behavior shows the principle of indeterminacy of Heisenberg and its philosophical implications. Thus, the main objective of this research is to seek to integrate quantum behavior, which takes place at the atomic scale, especially in the high school level. Some guidance on how to apply this work in other levels of education appear throughout the text and in the appendices. Introducing the dual behavior wave-particle, the electron, the probabilistic interpretation and the uncertainty principle. We believe that students will be able to understand a number of phenomena that occurs on scales that are not the classical mechanics of the domain when in contact with these topics. This topic is part of the contemporary modern physics content that is being addressed in texts and entrance exam books. In addition, some of the new technologies using quantum physics, from electronic microscopes, nanotechnology, quantum computing, semiconductors, diodes (including LED), transistors, computers, tablets, GPS, satellites, radar, aircraft, lasers, code scanners bars, military defense systems, CD and Blu-Ray players, encryption, photoelectric cells, various sensors, basically, everything is electronic. One of the goals of the work is to check what prior knowledge the student body has, before contact with quantum physics content, so the part of common sense on this issue. In addition, we intend to verify that the student is able to: i) distinguish, at the end of the application of this research, that the laws of physics at atomic scales are different from the laws of classical physics, ii) the importance of quantum mechanics in technology and society.

A Engenharia apresenta como uma de suas características, a necessidade de investigação de sistemas, para se obter o máximo de resultado destes. E Planejamento de Experimento é um método, que pode suportar esta necessidade, porém a complexidade intrínseca ao método cria barreiras no entendimento, e consequentemente no uso, podendo se considerar a estatística um dos agentes mais significativos, portanto faz-se necessário utilizar abordagens mais eficientes, para o ensino deste método. As tradicionais abordagens pedagógicas não se mostram suficientes para favorecer a assimilação da essência do Planejamento de Experimento, pois ou seu foco se direciona quase que totalmente a estatística ou, quando se usa recursos tecnológicos, a ferramenta se torna protagonista, por se tratar de softwares complexos para análises, e adequado ao uso por especialistas. Assim essa dissertação vem com o objetivo de propor um software com características essencialmente didáticas, que venha a preencher esta lacuna, o qual foi denominado “The Cake”, metáfora que faz alusão à variabilidade total de um experimento, e que tem suas partes tomadas pelos efeitos controláveis e incontroláveis. Desta forma, este software foi desenvolvido, buscando interfaces amigáveis e similares aos livros texto, para ser de fácil uso e proporcionar interação com o usuário, e apresentar as análises de maneira gradativa.
The Engineering presents as one of its characteristics, the need of investigation of systems, in order to obtain the maximum result of these. Design of Experiments is a method that can support this need, but the intrinsic complexity of the method creates barriers in its understanding, and consequently on the use and statistic can be considered one of the most significant agents, therefore it is necessary to use more efficient approaches, for the teaching of this method. The traditional pedagogical approaches are not sufficient enough to favor the assimilation of the essence of Design of Experiments, since its focus is almost entirely on statistics or, when using technological resources, the tool becomes a protagonist because it is software complex for analysis, and suitable for use by specialists. So this dissertation comes with the objective of proposing software with characteristics essentially didactic that will fill this gap, which was denominated "The Cake", metaphor that alludes to the total variability of an experiment, and that has its parts taken by the controllable and uncontrollable effects. In this way, this software was developed, searching for friendly interfaces and similar to text books, to be easy to use and provide user interaction, and present the analyses in a gradual way.

This thesis deals with the possibility of applying the method of Design of Experiments (DoE) on specific data. In the first chapter of theoretical part, this method is described in detail. The basic principles and guidelines for the design of the experiment are written there. In the next two chapters, factorial design of the experiment and response surface design are described. The latter one includes a central composite design and Box-Behnken design. The following chapter contains practical part, which focuses on modelling firing range of ball from a catapult using the above three types of experimental design. In this work, the models are analysed together with their different characteristics. Their comparison is made by using prediction and confidence intervals and by response optimizing. The last part of the thesis comprises overall evaluation.

In this thesis, the design of experiment is studied. Firstly, a theoretic background in mathematical statistics necessary for understanding is built (chapter 2). The design of experiment is then presented in chapters 3 and 4. Chapter 3 is divided into several subchapters in which its brief history is provided as well as its complex theoretic description (basic principles, steps for planning, etc.). Chapter 4 deals with particular types of the design of experiment (Factorial experiments or Response surface design). Simple examples are provided to illustrate the theory in chapters 3 and 4. Last part of the thesis is strictly practical and focuses on an application of the theory for particular data sets and its evaluation (chapter 5).

The aim of Master's thesis is to apply statistical methods in production process. The assignment of the thesis is to describe and evaluate pressing process which is the part of posistor production. The first theoretical part contains introduction to the mathematical statistics, verifying assumptions about the data, describing the regression analysis, the analysis of variance and the part of the design of experiment. The second practical part is focused on design, performing and interpreting of experiments. The thesis is developed according to requirements of company EPCOS s.r.o. Šumperk. Statistical program MINITAB Rlease 14, which is supported by company, was used for all computations.

This essay discusses different opinions about experimental archaeology. To start with literature was examined and a questionnaire was sent out to students and working archaeologists. The possibility for experiments to mediate archaeology to people without an education in archaeology is lifted and is also mentioned in the questionnaire. In the discussion part of the essay the results from the questionnaire and the literature are used to see what opinions are the strongest. The mediating is also discussed and the result is compiled in the conclusion. There are different opinions about experimental archaeology, but no prominent difference between what students and archaeologists answered. It is possible to see different opinions in the literature, but concerning the mediating most of the writers agree that the experimental archaeology is a good method to communicate with the laymen.

Este trabalho é composto por duas partes distintas e complementares: a primeira apresenta o romance autoficcional Menina do Cerrado, colagem de resíduos da memória e da fabulação criativa engendrada especialmente para a presente composição. A segunda agrega um posfácio com considerações sobre elementos de cunho prático-teórico que alicerçam a ficção. A união das duas partes realça o esforço de fazer a aproximação de percepções artísticas a determinados conceitos da filosofia recente.
This work consists of two distinct but complementary sections: the first presents the auto-fictional novel Menina do Cerrado (The Girl from the Cerrado), a collage of bits of memories and the creative figment specially designed for this composition. The second one adds an afterword with considerations about practical and theorectical elements which support the fiction. Both parts together highlight the application of approaching artistic perceptions and some concepts of new philosophy.

The thesis examines the experience of English local authorities under the arrangements recommended by the The Care of Children Committee, chaired by Dame Myra Curtis, Principal of Newnham College, Cambridge. The committee was set up in 1946 by three government departments to enquire into existing methods of care for children who have from loss of parents or from any cause whatever been deprived of a normal home life with their own parents or relatives; and to consider what further measures should be taken to ensure that the children are brought up under circumstances best calculated to compensate them for the lack of parental care". The committee recommended that the children in public care should come under one department in each authority with a children's officer as head and free of other duties. In paragraph 441 of their report they said, "this may indeed be said to be our solution to the problem referred to us". The committee examined the existing statutory provisions and administrative arrangements and said how the children were cared for at the time. Their extensive list of recommendations was broadly put into effect by the Children Act 1948, which remained in force until 1 April 1971 when social services for children were taken over by the social services committees under the Local Authority Social Services Act of 1970.

Experiment Station Road is an original work of fiction serving as a collection of short stories set in Hayford, Oregon and Las Vegas in 1962-1972. Each story presents the point of view of a resident in Hayford. The stories are written to function independently, but when read as a collection present insight to cultural diversity, intricate relationships and the ignorance of prejudice.

A decisão estratégica é tipicamente não estruturada, no sentido de que não existe processo semelhante na memória da organização. Essa estruturação corresponde ao cenário exposto de forma clara, com suas questões, hipóteses e objetivos. A qualidade da decisão estratégica depende principalmente do processo e da competência daqueles que participam dela. Gerar alternativas criativas e viáveis é uma etapa fundamental do processo de tomada de decisão, responsável em grande parte pela qualidade almejada. Entretanto, as pesquisas sobre geração de alternativas têm indicado consistentemente que as pessoas não são eficientes nessa atividade. Buscando-se as explicações para esse fato surgiram lacunas na literatura que serviram de inspiração para o presente estudo. Qual a influência das heurísticas e da isolação entre as etapas convergente e divergente na geração de alternativas? Para explorar essas lacunas e conhecer o desempenho do administrador brasileiro ao gerar alternativas foi realizado um experimento com 174 alunos de cursos MBA, de 4 escolas da Grande São Paulo. O resultado desse experimento propiciou algumas conclusões interessantes como a confirmação do baixo desempenho em geração de alternativas. O desafio para preencher as lacunas observadas permanece e as hipóteses da pesquisa, relacionando as heurísticas e a isolação como fatores que influenciam o desempenho, não foram aceitas. O estudo é uma confluência da pesquisa experimental, oriunda da psicologia cognitiva da decisão, com a visão da ciência da decisão organizacional. Essa linha de pesquisa se mostrou praticamente inexplorada nos estudos em administração desenvolvidos no Brasil.
The strategic decision-making is typically non-structured because there is no similarity process in the memory of the organizations. This structural model would involve a context of elements such as questions, hypotheses and objectives exposed in a quite clear way. The quality of the strategic decision-making depends mainly on its own process and on the competence of the individuals involved. An essential part of the making decision process is to generate creative and viable options that are also responsible for the quality of the process. However, researches on option-generating procedures have consistently suggested that people are not efficient in this kind of task. The present study was inspired by the fact that the current literature lacks studies explaining the reasons why this happen. What is the influence of the heuristics and isolation strategies on the convergent and divergent phases for generating options? In order to investigate this issue and understand the performance of the Brazilian managers for generating options, an experiment was conduct in 174 individuals studying in MBA courses at 4 educational institutions in the urban city area of São Paulo. The results led to some interesting conclusions such as the confirmation of the poor performance for generating options. The challenge and the lack remain mainly because the hypotheses tested, i.e., the heuristic and isolation strategies for generating options, were not effective. The present study is a confluence of two different decision approaches: the experimental research (based on cognitive psychology) and the management science. This line of research hasn’t been explored in the management field in Brazil.

The normative moral code is considered to be such that it applies universally to all or at least to all who can understand and govern their behavior by it. All or almost all common folk think of and use their own moral codes as them being normative in that for example there simply seem to them to exist “oughts” that apply to all and that there simply, straightforwardly are “things” that are right and wrong, good and bad. Gert Bernard and Gert Joshua have written an article on the topic of defining morality, with the title of “The Definition of Morality”. The authors suggest that the terms ‘normative morality’ refer to a code of conduct that, given some specified conditions, would be put forward by all rational persons. The authors take this formulation as entailing true and important definitional features of what normative morality is, although the authors think of this basic definition, conception as not being complete and that some additional feature hence is lacking but that any such candidate addendum to the definitional basic schema that they surveyed within the article seemed to be controversial, contested. Normative morality seems apt to investigate by creating thought-experiments wherein the participants are for example, envisioned choosing to endorse, put forward or act in accordance with a moral code. Within this large investigative project into normative morality with the help of thought-experiments it seemed to me that there was an under-representation of thought-experiments exhibiting some worthwhile and relevant features and I felt that it was a warranted project to create a thought-experiment which concurrently exhibited these features. Such an experiment could be thought of as an unusual “puzzle-piece” which could be valuable in contributing to furthering the completion of the “puzzle”, i.e. what normative morality is and its moral code. These three features were: i) a high degree of aptness for investigating a major part of or the complete normative moral code and ii) a high degree of freedom pertaining to the participants, e.g. their actions, thoughts etc., as well as iii) a high degree of confidence or warrant concerning what the participants would do, think, feel etc. within the thought-experiment. A thought-experiment, the Normative Moral Codes Workshop (NMCW) was hence created, which was aimed at investigating normative morality and its code and which exhibited these features. It is a thought-experiment mimicking an actual empirical study wherein the participants are given the task to together put forward the moral code for them, that would apply to them and that would cover a major or complete part of what they consider their moral codes to entail. The participants employed within my run of the NMCW thought-experiment were all currently living adult persons who I knew well. The core or main aim of this essay was to investigate whether it would or would not be the case that most or all participants within my run of the thought-experiment the NMCW would decide to put forward the code together with the chosen formulation of the thesis being, that it would not be the case that most or all participants would put forward the code within my run of the NMCW thought-experiment. Part of the core aim was also to elucidate why the thesis was supported or not supported as well as how strong the support was for the outcome of the experiment, i.e. the outcome of a code being put forward or not. The essay also has some minor aims which radiate out from the core aim (see below). As the thought-experimenter, I then reported on the events that I envisioned as happening within my run the NMCW thought-experiment as my selected participants grappled with the task and their decision to put or not put forward the code together that would apply to them. The finding was that the thesis was supported and that the support was robust in that I could identify several reasons the participants had against putting forward the code and I found very little in terms of reasons among the participants for putting forward the code. The essay also had some minor aims to selectively discuss a few further relevant and interesting issues radiating out from the core aim. These minor aims revolved around discussing some selected salient features of the NMCW including how they could relate to the outcome. One such selected salient feature was the feature of the employed participant sample of my run of the NMCW. I for example, discussed the potential extension of it not being the case that most or all participants would decide to put forward the code, if the participant sample would have been modified but still employed currently living5adults and I ended up being of the opinion that pertaining to most potential samples a similar outcome as the one envisioned within my run of the NMCW would be expected. I also wanted to discuss some further selected salient features of the NMCW within the context of addressing whether the NMCW, given its features ought to be considered an unsound, inapt experiment for investigating normative morality, given Gert’s and Gert’s conception of normative morality, since if this was the case the outcome of the experiment ought to be disregarded, given no weight. Although, I did find potential targets for criticism of the NMCW experimental design I did not find any reasons strong enough to disqualify the NMCW experiment as an experiment inapt, unsound for investigating normative morality, given the features of normative morality entailed within the suggested basic definition provided by Gert and Gert. Finally, I also aimed to selectively discuss some aspects of what it could mean pertaining to the conception of normative morality, according to Gert and Gert, that the thesis was supported. For example, given one interpretation the outcome could be taken to provide support for the non-existence of a normative moral code, but given another be taken to mean that addenda has to be identified and added to the basic conception of normative morality and that such addenda would be such that they would disqualify the NMCW (and its outcome) as a sound and apt thought-experiment to be employed in investigating normative morality. I also attempted to briefly illustrate how the NMCW thought-experiment could be used as a substratum facilitating the identification and clarification of such potential addenda to the basic conception of normative morality, suggested by Gert and Gert, and I also suggest some potential candidate features of the NMCW that further potential specifications added to the basic conception of morality ought to be able to disqualify, exclude as acceptable features of experiments aimed at investigating normative morality. In this way, an unusual, under-represented kind of thought-experiment, “puzzle-piece” when it comes to the large investigative project of employing experiments in order to acquire further insight into normative morality, i.e. “the puzzle”, can regardless of whether it seems to fit or does not seem to fit the “puzzle”, still be employed in such a way as to potentially provide further insight into “the puzzle”. This since even when a “puzzle-piece” does not seem to fit the “puzzle”, “seeing” and understanding how and why could provide us with information about the “puzzle”.
Den normativa moraliska koden anses vara sådan att den gäller universellt för alla eller åtminstone för alla som kan förstå den och reglera sitt beteende i enlighet med den. Alla eller nästan alla vanliga människor tänker och använder sig av sina moraliska koder som om dessa koder vore normativa, normerande genom att det t. ex. för dem helt enkelt verkar finnas ”måsten” som gäller alla och att det ”rakt upp och ner” verkar finnas ”saker” som helt enkelt är rätt och fel, gott och ont. Gert Bernard och Gert Joshua har skrivit en artikel kring ämnet hur man kan definiera moralen med titeln “The Definition of Morality” (sv. ”Moralens Definition”). Författarna föreslår att termen ’normativ moral’ (eller den ’normativa moralen’ i bestämd form) gäller en kod som reglerar hur man bör uppföra sig som givet vissa specificerade förhållanden är sådan att alla rationella personer skulle omfamna och förespråka den. Författarna anser att denna formulering innehåller viktiga och sanna egenskaper hos definitionen kring vad normativ moral är, även om författarna anser att denna basala, grundläggande definition, konception inte är fullständig och att därför vissa ytterligare definitions egenskaper, specifikationer saknas men att alla granskade kandidat-tillägg till denna basala definition som undersöktes inom artikeln verkade vara kontroversiella, enligt författarna. Normativ moral verkar lämplig för att undersökas genom att skapa tankeexperiment inom vilka deltagarna tex kan föreställas stödja, lägga fram eller agera i enlighet med en moralisk kod. Inom detta stora undersökande projekt av normativ moral med hjälp av tankeexperiment så verkade det enligt mig som om det fanns en under-representation av tankeexperiment som uppvisade vissa värdefulla och relevanta egenskaper och jag ansåg att det var ett rättfärdigat projekt att skapa ett tankeexperiment som uppvisade dessa värdefulla och relevanta egenskaper. Ett dylikt experiment kunde anses vara en ovanlig ”pusselbit” som kunde vara ett värdefullt bidrag till slutförandet av ”pusslet”, dvs vad normativ moral är och dess kod. De tre under-representerade egenskaperna var i) en hög grad av lämplighet för att undersöka en stor del av den normativa moraliska koden6eller den kompletta koden och ii) en hög grad av deltagarfrihet, exempelvis avseende deltagarnas handlingar, tankar osv samt iii) en hög grad av förtroende eller rättfärdigande avseende vad deltagarna skulle göra, tänka, känna osv inom tankeexperimentet. Tankeexperimentet, den Normativa Moraliska Kods Workshoppen (NMKW) skapades därför med målsättningen att undersöka den normativa moralen, dess kod samt att experimentet då skulle uppvisa de ovan nämnda egenskaperna. Det är ett tankeexperiment som liknar, ”speglar” en riktig empirisk studie inom vilka deltagarna ges uppgiften att tillsammans stödja och lägga fram den moraliska kod som skulle gälla för dem, reglera deras uppförande och som till en stor del eller fullständigt skulle täcka, innehålla det som de ansåg att deras moraliska koder innehöll. Deltagarna som användes inom min körning av tankeexperimentet var alla nu levande vuxna person som jag ansåg att jag kände väl. Kärn- eller huvudmålsättningen med uppsatsen var att undersöka huruvida det skulle eller inte skulle vara fallet att de flesta eller alla deltagare inom min körning av NMKW tankeexperimentet skulle bestämma sig för att tillsammans lägga fram och stödja en kod, med den valda formuleringen för tesen enligt, det skulle inte vara fallet att de flesta eller alla deltagare skulle lägga fram och stödja koden inom min körning av NMKW experimentet. Som en del av kärnmålsättningen var det att utreda varför tesen var eller inte var stödd samt utreda hur starkt stödet var för utfallet av experimentet, dvs utfallet att en kod lades fram eller inte lades fram. Uppsatsen har även mindre eller bi-målsättningar som strålar ut från uppsatsens huvudmålsättning (se nedan). I min roll som tanke-experimenteraren så rapporterade jag sedan kring vilka händelser som jag föreställde mig, som jag ”såg” uppträda inom tanke-experimentet NMKW då mina valda deltagare tog sig an uppgiften som de ombads att utföra, dvs att tillsammans lägga fram och stödja den kod som skulle komma att gälla dom själva, att appliceras på dom själva. Fyndet var att tesen stöddes och att detta stöd var robust eftersom jag kunde identifiera flera skäl hos deltagarna mot att lägga fram koden medan jag fann mycket litet i form av skäl hos deltagarna för att lägga fram koden. Uppsatsen hade även en del mindre målsättningar att selektivt diskutera några ytterligare relevanta och intressanta spörsmål som strålade ut från uppsatsens huvud-målsättning. Dessa mindre målsättningar kretsade kring att diskutera vissa valda tydliga, centrala egenskaper hos NMKW experimentet samt hur dessa kunde tänkas vara relaterade till experimentets utfall. En sådan egenskap vara den specifika deltagargruppen som användes vid min körning av experimentet. Jag diskuterade till exempel, den potentiella extensionen av utfallet att det inte var fallet att de flesta eller alla deltagare valde att lägga fram koden, ifall deltagargruppen modifierades men fortfarande bestod enbart av nu levande vuxna människor och min värdering var att ett liknande utfall, som vid min körningen av NMKW, verkade troligt för de flesta potentiella grupper av deltagare. Jag ville också diskutera vissa valda tydliga, centrala egenskaper hos NMKW experimentet inom kontexten kring huruvida NMKW experimentet givet dessa egenskaper, borde anses vara ett osunt, olämpligt experiment för att undersöka den normativa moralen, givet Gerts och Gerts konception av denna. Detta, eftersom om detta vore fallet så borde utfallet av experimentet förkastas och inte ges någon vikt. Trots att jag hittade potentiella saker att kritisera hos den experimentella designen hos NMKW så hittade jag inte några tillräckligt starka skäl för att diskvalificera NMKW experimentet som ett olämpligt, osunt experiment för att undersöka den normativa moralen, givet den normativa moralens egenskaper beskrivna, täckta inom Gerts och Gerts föreslagna basala, grundläggande definition av denna. Slutligen så ville jag även selektivt diskutera vissa aspekter kring vad det kunde betyda för konceptionen av den normativa moralen, enligt Gert och Gert, att tesen stöddes. Exempelvis, så givet en tolkning så kunde utfallet ses som ett stöd för icke-existensen hos den normativa moraliska koden, medan givet en annan tolkning så kunde utfallet anses betyda att ytterligare addenda till den basala definitionen av den normativa moralen måste identifieras och adderas till definitionen och att dylika addenda skulle komma att vara sådana att de skulle diskvalificera NMKW experimentet och dess utfall som ett sunt och lämpligt experiment att användas för att studera den normativa moralen, nu med dess extenderade specifikation. Jag försökte sedan att illustrera hur NMKW tankeexperimentet kunde användas som ett substrat för att underlätta identifieringen och förtydligandet av dylika potentiella tillägg till den basala konceptionen av den normativa moralen enligt Gerts och Gerts förslag, och jag föreslog även vissa potentiella kandidat egenskaper hos NMKW experimentet som dylika ytterligare tillägg till den basala konceptionen borde kunna diskvalificera, exkludera som acceptabla egenskaper hos experiment designade för att undersöka den7normativa moralen. På detta sätt så kan en ovanlig, underrepresenterad typ av tankeexperiment, ”pusselbit” när det gäller det stora undersökningsprojektet som använder sig av experiment för att erhålla ytterligare insikter inom den normative moralen, dvs ”pusslet”, oberoende om det verkar passa eller inte passa in i ”pusslet”, ändå användas på ett sådant sätt så att det potentiellt kan leda till ytterligare insikter kring ”pusslet”. Detta eftersom även när en ”pusselbit” inte verkar passa in i ”pusslet” så kan ”seendet”, förtydligandet och förståelsen kring hur och varför, ändå potentiellt förse oss med information om ”pusslet”.

Esta pesquisa é fruto do desenvolvimento de uma sequência didática sobre o comportamento das entidades físicas: partícula, onde e partícula-onda no Experimento da Supla Fenda, numa versão adaptada de Feynman e colaboradores e foi desenvolvida com estudantes de terceira série do ensino superior do curso de Química, disciplina Química Quântica, de uma universidade pública estadual. O objetivo geral do estudo foi discutir os fundamentos e práticas de experimentos mentais, tendo como parâmetro a utilização de diversas alternativas didáticas e seus desdobramentos para o ensino nas disciplinas científicas. A pesquisa de cunho qualitativo ancora-se nos fundamentos dos experimentos mentais e tem por base as teorias que visam promover a comunicação verbal e escrita dos conhecimentos científicos. O problema de pesquisa originou-se das dificuldades que os estudantes demonstravam em sala de aula para explicar e debater suas idéias, de maneira significativa, inteligível e dinâmica, quando estas exigiam deles o domínio da verbalização de conhecimentos científicos sobre o experimento da dupla fenda. Para interpretação e análise dos dados, utilizou-se a vertente interpretativa por meio de instrumentos e técnicas que permitem, principalmente, a descrição e interpretação de fatos e fenômenos, a recuperação de sentidos, tendo como base a investigação interpretativa do conjunto de materiais empíricos que se transformaram em textos. Os resultados revelam que os procedimentos didáticos utilizados são relevantes por possibilitarem a problematização, a discussão, o uso da imaginação e da linguagem verbal e escrita, pouco usuais em contextos de aulas de Química Quântica. Com relação aos textos, tanto aqueles transcritos das discussões e das falas dos estudantes quanto os que foram produzidos durante o desenvolvimento da pesquisa, por solicitação do professor...
This research is the result of the development of a didactic sequence on the behavior of physical entities: particle, wave and wave-particle in the Double-Slit Experiment, in an adapted version from Feynman and assistants, which was developed with university students from the third grade of the Chemistry course, in the discipline of Quantum Chemistry, at a Brazilian public state university. The study aimed to discuss the fundaments and practices of thought experiments by using several didactic alternatives and its unfoldings to the teaching of scientific disciplines. The research, of qualitative basis, is anchored to the fundaments of thought experiments grounded on theories aiming to promote verbal and written communication of scientific knowledge. The research problem focuses on the difficulties that the students show in the classroom in order to explain and discuss their ideas when theses require that they master verbalization of scientific knowledge on the double-slit experiment in a meaningful, significant and dynamic manner. To the purpose of data interpretation and analysis, we used the interpretative perspective by means of the methodological and theoretical. Results revealed that the didactic procedures used are relevant since they allow problematization, discussion, the use of imagination and of verbal and written language, quite rare in classroom contexts of Quantum Chemistry. Regarding the texts, both the ones transcribed during the discussions and the students' speeches and those produced during the development of the research, required by the teacher, deserve attention. The text productions were found considerably reduced, fragmented, lacking progression and continuity of ideas, and also lacking the interconnected sequence of the parts that constitute an articulated whole. By means of discourse analysis, we detected loss of the line of unity that assures its interpretability... (Complete abstract click electronic access below)

Two topics related to the experimental design are considered in this thesis. On the one hand, the uniform experimental design (UD), a major kind of space-filling design, is widely used in applications. The majority of UD tables (UDs) with good uniformity are generated under the centralized {dollar}L_2{dollar}-discrepancy (CD) and the wrap-around {dollar}L_2{dollar}-discrepancy (WD). Recently, the mixture {dollar}L_2{dollar}-discrepancy (MD) is proposed and shown to be more reasonable than CD and WD in terms of uniformity. In first part of the thesis we review lower bounds for MD of two-level designs from a different point of view and provide a new lower bound. Following the same idea we obtain a lower bound for MD of three-level designs. Moreover, we construct UDs under the measurement of MD by the threshold accepting (TA) algorithm, and finally we attach two new UD tables with good properties derived from TA under the measurement of MD. On the other hand, the problem of selecting a specific number of representative points (RPs) to maintain as much information as a given distribution has raised attention. Previously, a method has been given to select type-II representative points (RP-II) from normal distribution. These point sets have good properties and minimize the information loss. Whereafter, following similar idea, Fu, 1985 have discussed RP-II for gamma distribution. In second part of the thesis, we improve the discussion of selecting Gamma RP-II and provide more RP-II tables with a number of parameters. Further in statistical simulation, we also evaluate the estimation performance of point sets resampled from Gamma RP-II by making comparison in different situations.

Consumers make purchasing decisions every day. Among their purchases, consumers shop for hedonic and utilitarian products. In general, hedonic consumption is related to fun, pleasure, excitement, fantasy, experimental situations, or sensual pleasure. On the other hand, utilitarian consumption is related to instrumental and functional needs or products. Studies in psychology have shown that the information processes used to understand words and pictures are different. Since marketing researchers employ both types of stimuli, it is necessary to test how different stimuli can influence consumer behavior. Therefore, this study verified the influence of hedonic and utilitarian purchases and presentation types (pictures versus words) on consumers\' perceptions of justice and price fairness based on anger as a mediators and construal level theory. Because discriminatory pricing is a widely employed market practice, it was used the price changing (increasing or decreasing) contexts in the studies to manipulate perception of justice and price fairness. Based on that, ten hypotheses were developed and divided into sub items, which were tested with behavioral or physiological studies. The physiological data were collected by an electrocardiogram, electrodermal, and electromyography. The data analyses were done with analyses of variance (ANOVA), analyses of covariance (ANCOVA), and generalized estimation equations (GEE). The main result was that in picture presentations (low construal level), when consumers pay more than others to purchase utilitarian products, they perceive the situation as less just and more price unfairness compared to when the product is hedonic. In a word presentation (high construal level), the perceptions of justice, price fairness, perception of value, and the intention to repurchase are lower with the presentation of utilitarian products compared to hedonic products. In terms of physiological analyses, attention, arousal, and valence were tested to compare the product and presentation types. This study is relevant to marketing theory, as many academics utilize words and pictures as stimuli, but few address the differences due to representation types. By studying different products, such as hedonic and utilitarian, and using consumers\' affective and rational properties, it was found that the anger evoked in consumers by products are mediators in price fairness perception. This dissertation also contributes to understanding product evaluations in post-purchase situations, as opposed to during the choice process, which is found in the literature most often. For practitioners, this study makes important contributions by showing that the way a product is exposed (with words or pictures) influences the perception of justice when consumers realize that discriminatory pricing is being practiced.
Os consumidores tomam decisões de compra frequentemente, envolvendo produtos hedônicos e utilitários. Em geral, o consumo hedonista está relacionado com diversão, prazer, excitação, fantasia, prazer sensitivo até mesmo experienciar a compra. Por outro lado, o consumo utilitário está relacionado com as necessidades ou produtos instrumentais e funcionais. Estudos em psicologia têm mostrado que os processos de captação das informações para o entendimento das palavras e imagens são diferentes. Já que os pesquisadores de marketing empregam os dois tipos de estímulos em seus estudos, é importante testar como as diferentes formas de estímulos podem influenciar o comportamento do consumidor. Desta forma, esta dissertação buscou verificar a influência de diferentes formas de apresentação dos produtos (por figuras e palavras) hedônicos e utilitários na percepção de justiça e na justiça de preços, e seu mediador (raiva) com base na teoria de construal level quando existe uma mudança de preço pago pelo consumidor. Como preços discriminatórios é uma prática amplamente utilizada no mercado, é relevante entender como os consumidores percebem e reagem em situações de mudança (aumento ou diminuição) de preços. Com base neste contexto, dez hipóteses com subitens foram desenvolvidas. Estas foram testadas por meio de estudos comportamentais ou fisiológicos. Os dados fisiológicos foram coletados por meio de eletrocardiograma, condutância da pele e eletromiografia. As análises de dados foram realizadas com análise de variância (ANOVA), análise de covariância (ANCOVA), e equações de estimação generalizadas (GEE). Os principais resultados desse estudo foram que quando o estímulo foi a apresentação de produtos por figura (baixo nível de interpretação), e quando os consumidores pagaram mais que outras pessoas, em compras de produtos utilitários, eles perceberam a situação como menos justa e o preço mais injusto quando comparados a compras de produtos hedônicos. Entretanto, em apresentações de produtos por palavras (alto nível de interpretação), a percepção de justiça, de justiça de preço, percepção de valor e de intenção de recompra foram menores quando os produtos eram utilitários comparados aos produtos hedônicos. Em relação às análises fisiológicas, foram testados os produtos e a forma de apresentação quanto a sua atenção, excitação e valência. Ao estudar os diferentes tipos de compra hedônicas e utilitárias e as propriedades afetivas e cognitivas dessa compra, verificou-se que a raiva evocadas pelos consumidores na situação de preço mais elevado é um mediador da percepção de justiça de preço. Esta dissertação contribui para a compreensão das avaliações de produtos em situações de pós-venda, ao contrário da maioria dos estudos da literatura que focam no processo de escolha de um produto. Para o mercado, este estudo faz importantes contribuições ao mostrar que a forma como o produto é exposto (com palavras ou imagens) influencia na percepção de justiça quando os consumidores percebem que preços discriminatórios estão sendo praticados.

An economic literature concerns instruments to improve the preference elicitation methods for the reform-based governmental programs. We construct an instrument for the budget allocation method using a Cobb-Douglas functional form. We apply the instrument to the survey data which is collected for Swedish Recreational Fishing Industry to elicit the preferences for governmental management actions. We analyze the elasticity or weights in the instrument by the binary logit and censored regression models and by comparing the significant estimates by the gross and net effects we get results which increase credence to the instrument we apply.
I am heartily thankful to my supervisor, Thomas Laitila, whose guidance and support from the initial to the final level enabled me to develop the thesis.More, I offer my regards to Anders Lunander who supported me in any respect during the completion of the thesis.

Hybrid optical packet/circuit switched networking architectures are increasingly becoming an interesting research field. They integrate multiple switching techniques to achieve better quality of service and to improve resource utilization. The aim of this study was to investigate the performance of TransPacket FUSION Ethernet H1 node, which is being developed based on the original idea of OpMiGua hybrid optical network. The work was focused on several key performance elements: packet delay, packet loss rate and packet delay variation of the hybrid network. The research background and the quality of service methods utilized in hybrid network and OpMiGua were studied in this project. The performance of H1 node was tested based on one applicable scenario. We investigated and analyzed the results obtained from the Spirent test center, and derived a mathematical model of H1 node performance respect to each aspect. Furthermore, the experiment results were verified with usability of H1 node in comparison with the ITU recommendations. The results in our experiment scenario showed that H1 node provides a high quality of service.

This thesis reports the development of sonoelectrochemistry as a technique for sample analysis. Complementary modelling gives an insight into the mass transport and electrode reaction mechanisms. Separate studies were conducted as follows: - Initially an copper(II) acetate buffer system was used as its speciation can be determined. In order to establish under which conditions analysis could be conducted the effect of speciation was examined. These were applied to the Anodic Stripping Voltammetry (ASV) determination of copper in the acetate solution and to facilitate the use of a traditionally inhospitable electrochemical medium: real ale with minimal pre-treatment. Both gave detection limits of the range (1-100) μg L^-1 and in quantitative agreement with Atomic Absorption Spectroscopy. - The effect of acoustic streaming under mild insonation was studied by modelling Square Wave Voltammetry (SWV) of ASV and was found, when compared to experiment, to be the dominating factor. When the latter is strongly present two distinct mass.transport regimes were identified. Studies of chemical and electrochemical processes suggested that the acoustic streaming model fails under more extreme conditions. - SWV voltammetry was modelled for reversible electrochemical reactions leading to a refinement of existing analytical theory and the ASV modelling extended to account for surface morphology and finite electrode kinetics. Droplets on an electrode surface subjected to a potential sweep give rise to voltammetric traces attributed to charge insertion. Three mechanisms for this are proposed: (i) charge injection at the droplets surface, (ii) charge injection at the three phase boundary and (iii) the droplet is saturated with counter ions and electron transfer occurs at the electrode surface. These are solved numerically and incorporate Regular Solution Theory to account for non-ideal interactions. Comparing with experimental data an approximate model identified the processes occurring for small droplets. A Marangoni-type convection is suggested for larger droplets.

An architecture for online remote operation of a polymer crystallization experiment was refined, beta tested in actual use conditions, and extended based on feedback from those tests. In addition, an application for graphically simulating macroscopic crystal spherulite growth was developed for use as an educational tool. Finally, the experiment was used in the design process for modifying the generic iLab framework to incorporate interactive functionality. Specifically, a reservation model and design changes to the experiment storage and service broker were proposed based on the Polymerlab, and the experiment was used as a testbed for initial implementation of some of the proposed systems.

Detta examensarbete behandlar pedagogers syn på experiment i skolans tidigare år i naturvetenskapsundervisningen. Vårt huvudmål med examensarbetet var att undersöka faktorerna som underlättar respektive försvårar utförande av experiment i undervisningen för grundskolepedagoger. Vi ville även undersöka vilka typer av experiment som utnyttjas samt vilka mål som pedagogerna vill uppnå med utförandet av experimenten. Studien har genomförts på tre olika skolor rund om i Skåne. Vi har med hjälp av intervjuer genomfört en kvalitativ undersökning. Resultatet visar att alla pedagogerna ansåg att experiment har en positiv inverkan på elevernas lärande men det var bara några få som använder sig av det som en inlärningsmetod. Resultatet visar även att alla pedagogerna vill att eleverna själva ska utföra experimenten men nästan alla pedagogerna utför själva experimenten först innan eleverna själva får prova. De pedagoger som undervisar i skolor med elever med svenska som andra språk, använder experiment till att stärka det svenska språket hos eleverna.

My work is an exploration of new media that demonstrates the influence a community has on visual communication. The community reveals content as objects go unnoticed after they become a permanent part of the landscape and assumptions are made from cultural archetypes. Through exploration, immersion, and reflection, I am able to recognize the invisible and expected, establish a familiarity with a community, and design responses that communicate directly to it.

The conception of René Descartes as the arch-rationalist has been sufficiently exploded in recent literature; however, there is still a large lacuna in our understanding of how empirical research and experimentation fits within his philosophy. My dissertation is directed at addressing just this problem. I contend that Descartes’ famed method is not a singular monolith but instead two interdependent methods: one directed at metaphysical and epistemological truth, while the other directed at empirical questions and contingent facts of the world. I claim there is evidence for this position not only in his actual scientific practice, but also in the rhetorical structure of the Discourse on Method and the Principles of Philosophy. In exploring the empirical side of Descartes’ method, I show how his unusual system produces a system of experiment designed to serve both as a discovery and verification tool at the same time. As a further application of my interpretation, I argue that the Passions of the Soul and Descartes’ ethical theory expressed in his correspondence must also be seen as part of his two-fold methodology. Instead of attempting to cast Descartes as a virtue ethicist or deontologist, as is normally done, I emphasize that Descartes’ ethics is centered on the mind-body union, and therefore, includes an empirical element as well. The end result is an ethics that requires a detailed study of mechanics, anatomy, physics, as well as medicine. Lastly, I show how this methodology can help us understand the works of some of his early followers: Claude Gadroys and Jacques Rohault. Both of these philosophers not only serve to ground my interpretation, but also to highlight aspects of Cartesian that have often been passed over. I show how the experimentalism of Jacques Rohault goes beyond the epistemological boundaries set up by Descartes, as signifies a new direction that will ultimately eclipse the Cartesian school of thought. In the case of Claude Gadroys, I present a concrete example of the exploitation of the over generality of Cartesian principles. In so doing, I show that while Descartes’ experimentalism was intended to rule out the possibility of occult causes, he in fact created a system that allowed for them, only under a different guise.

Hadronic matter makes about 14% of the known universe. The remaining 86% is Dark Matter (DM). Since it does not interact with the ordinary matter via electromagnetic force, DM is not visible and, to date, it escaped detection. The search for DM is one of the hottest topic in modern physics. Despite the increasing number of astrophysical and cosmological observations proving the existence, so far no particle physics experiment has detected DM yet. In a popular class of models, DM is composed of particles with mass in the MeV-GeV range, interacting with the Standard Model via a new force, mediated by a massive vector boson, the Dark Photon or A'. BDX (Beam Dump eXperiment) is an approved experiment searching for DM in the Dark Photon theoretical scenario. The experiment makes use of CEBAF (Continuous Electron Beam Accelerator Facility) 11 GeV electron beam impinging on the Jefferson Lab (Jlab) Hall-A beam-dump. The interaction of the energetic electrons in the beam-dump may lead to the production of Dark Photons through a bremsstrahlung-like radiative process. Subsequently, the A's decay to DM particle-antiparticle pairs, which travel almost unaltered through the length of the dump. A ~ 1 cubic meter detector made of CsI(Tl) (Thallium doped Cesium Iodide) crystals is located in the trajectory of the DM beam, 20 m downstream of the beam-dump. A fraction of the DM particles scatter off atomic electrons in the detector giving rise to a detectable electromagnetic shower of approximately 100 MeV. Thanks to the cosmic background suppression and the high intensity of the electron beam (up to 65 μA at 11 GeV), BDX will be able, with a 280 days run, to exceed by up to two orders of magnitude the sensitivity of current competitor experiments. A primary concern for BDX is in the estimation of beam related backgrounds from penetrating particles such as muons and neutrinos produced in the electron beam dump. A hodoscope detector, called BDX-HODO was placed downstream of the dump to measure the rates of these beam related processes and validate the necessary Monte Carlo simulations. Currently, the BDX collaboration is focused on the deployment and operation of a small detector, called BDX-MINI, built to perform a preliminary physics measurement searching for LDM at JLab. This test will pave the way to the realization of the full BDX experiment. This thesis is focused on the following topics: the muon flux measurement behind Jlab Hall A beam-dump with BDX-HODO, the evaluation of the BDX experiment reach, including an optimization study for the detector, the construction, commissioning and sensitivity estimate of the BDX-mini detector and the evaluation of the secondary positrons contribution to the sensitivity of BDX and other electron-beam thick-target experiments searching for DM in the Dark Photon paradigm.

El Large Hadron Collider (LHC) en la Organización Europea para la Investigación Nuclear (CERN), Ginebra, interrumpirá su operación en 2023 para ser mejorado a High Luminosity LHC (HL-LHC) y proporcionar colisiones entre protones con una energı́a en el centro de masa de √s = 14 TeV con una luminosidad de 1035 cm−2 s−1. ATLAS es uno de los experimentos alojados en el LHC que tendrá que ser mejorado para cumplir los nuevos requisitos impuestos por la mayor luminosidad. Las obras de mejora de ATLAS prevén la sustitución del Inner Detector por un detector de trazas interamente de silicio, el Inner Tracker (ITk), con una granularidad más pequeña y una mayor resistencia a la radiación, y la introducción del High Granularity Timing Detector (HGTD), que proporcionará información temporal de las trazas y de los vértices. Combinando las medidas de ITk y HGTD será posible resolver vértices cercanos en el espacio pero con suficiente separación temporal, lo cual mejora las prestaciones de ATLAS. En esta tesis se investigan dos nuevas tecnologı́as de detectores de silicio para aplicaciones en el HGTD y el ITk, la tecnologı́a de Low Gain Avalanche Detector (LGAD) y la de HV-CMOS. La tecnologı́a LGAD consiste en detectores planares de silicio n-on-p con un implante altamente dopado de tipo p debajo del electrodo de tipo n. Originalmente fue desarrollada para detectores de trazas resistentes a la radiación, pero la segmentación del electrodo demostró afectar al mecanismo de multiplicación y no se ha observado ganancia en los primeros dispositivos. Por otro lado, detectores LGAD delgados han mostrado una resolución temporal de aproximadamente 30 ps y fueron elegidos como de base para los sensores del HGTD. Estudios de sensores LGAD, antes y después de la irradiación, se realizaron por primera vez en el contexto de esta tesis. La tecnologı́a HV-CMOS originalmente aspriaba a producir sensores con pı́xel activo, con la ventaja, en comparación con los dispositivos hı́bridos estándar, de poder optar por el acoplamiento capacitivo. Sin embargo, durante el proceso de IyD, resultó claro que los dispositivos monolı́ticos en tecnologı́a HV-CMOS ofrecen las ventajas más prometedoras: una moderada resistencia a la radiación y la reducción de costos. Esta tesis incluye la caracterización de la primera muestra a escala completa de un chip HV-CMOS para el experimento ATLAS. Actualmente, esta tecnologı́a se tiene en cuenta como una opción de inserción para la capa externa del detector de pı́xeles del ITk.
The Large Hadron Collider (LHC) at the European Organization for Nuclear Research (CERN), Geneva, will interrupt its operation in 2023 to be upgraded to high luminosity (HL-LHC) and provide proton-proton collisions with a center of mass energy of √s = 14 TeV at a luminosity of 1035 cm−2 s−1. ATLAS, one of the two general purpose experiments at the LHC , will have to be upgraded to meet the new requirements given by the larger luminosity. Among other things the ATLAS upgrade foresees the replacement of the Inner Detector with a full silicon Inner Tracker (ITk), with finer granularity and improved radiation tolerance, and the introduction of the High Granularity Timing Detector (HGTD) that will provide timing information of tracks and vertices. Combining the measurements of ITk and HGTD it will be possible to resolve vertices close in space but separated in time, improving the ATLAS reconstruction performance. In this thesis two novel silicon detector technologies are investigated for applications in the HGTD and ITk, the Low Gain Avalanche Detectors (LGAD) and the HV-CMOS technologies. The LGAD technology consists of planar n-on-p silicon detectors with a highly doped p-type implantation underneath the n-type electrode. It was originally developed for radiation hard tracking detectors but the fine segmentation of the electrode proved to affect the charge multiplication mechanism and no gain has been observed on segmented devices. On the other hand, thin LGAD detectors have shown a time resolution of about 30 ps on the detection of minimum ionizing particles and it was chosen as baseline technology for the HGTD sensors. Studies of LGAD sensors, before and after irradiation were first performed in the context of this thesis. The HV-CMOS technology was originally aimed to provide active pixel sensors with the advantage, compared to the standard hybrid devices, of the AC coupling capability. However, during the R&D effort, it become clear that monolithic HV-CMOS devices offered the most promising advantages: moderate radiation hardness and cost reduction. This thesis includes the characterization of the first full scale HV-CMOS chip prototype for the ATLAS experiment. This technology is currently taken into account as a drop-in option for the outer layer of the ITk pixel detector.

This work presents on-orbit experiments conducted to validate SEU mitigation and detection techniques on FPGA devices and to measure SEU rates in FPGAs and SDRAM. These experiments were designed for the Cibola Flight Experiment Satellite (CFESat), which is an operational technology pathfinder satellite built around 9 Xilinx Virtex FPGAs and developed at Los Alamos National Laboratory. The on-orbit validation experiments described in this work have operated for over four thousand FPGA device days and have validated a variety of SEU mitigation and detection techniques including triple modular redundancy, duplication with compare, reduced precision redundancy, and SDRAM and FPGA block memory scrubbing. Regional SEU rates and the change in CFE's SEU rate over time show the measurable, expected effects of the South Atlantic Anomaly and the cycle of solar activity on CFE's SEU rates. The results of the on-orbit experiments developed for this work demonstrate that FPGA devices can be used to provide reliable, high-performance processing to space applications when proper SEU mitigation strategies are applied to the designs implemented on the FPGAs.

The purpose of this bachelor thesis is to present a tracking system for the Suaineadh satellite experiment. The experiment is a part of the REXUS (Rocket EXperiments for University Students) program and the objective is to deploy a foldable web in space. The assignment of this thesis is to develop a tracking system to find the parts from the Suaineadh experiment that will land on Earth. It is important to find the parts and recover all the data that the experiment performed during the travel in space. The implementation of this thesis investigates two different ways to track and find the experiment. The first way is to locate the experiment module by a Global Positioning System (GPS) and send the coordinates to a satellite modem, controlled by a programmed microprocessor. The other way is by using a radio beacon that sends a speciffic radio frequency. The results of this thesis presents a prototype for the tracking system with a GPS and the satellite modem and code example for the microprocessor. It also presents a working radio freqency beacon system on a Printed Circuit Board. The thesis had some unexpected incidents and had to change some directives. This rendered the work to take longer time then estimated. Despite the difficulties resulted this thesis in a working system to track the experiment.

Resumo: Esta dissertação foi um trabalho prático realizado com dois grupos de alunos do primeiro período semestral do Curso de Letras-Inglês da Universidade Federal do Paraná, em 1978. Antes do início das experiências, os 46 alunos da disciplina de Língua Inglesa I foram submetidos a pré-testes de Competência Comunicativa, Competência Gramatical e questionários nos quais revelariam suas atitudes em relação a aprendizagem de Inglês. Depois destes testes os alunos foram divididos em dois grupos do mesmo nível. Um grupo foi chamado "Grupo de Controle" enquanto que o outro foi chamado de "Grupo Experimental". Os dois grupos tinham aulas práticas de gramática cinco vezes por semana, durante 13 semanas. Além disso eles também participavam em três sessões experimentais, nas quais o grupo de controle tinha prática de laboratório e o grupo experimental praticava exercícios de conversação (TRANSACTIONAL DRILLS). O objetivo destas três sessões experimentais era desenvolver a competência comunicativa oral dos alunos. Depois do período de 13 semanas experimentais os alunos de ambos os grupos foram submetidos a pós-testes de Competência Comunicativa e Competência Gramatical além do questionário de atitude em relação ao aprendizado de Inglês. De acordo com os resultados obtidos nos pós-testes não havia nenhuma diferença entre os dois grupos quanto a competência gramatical e atitude em relação ao aprendizado de Inglês. Por outro lado o grupo experimental que havia praticado "Transactional Drills" era bastante superior ao grupo de controle em termos de Competência Comunicativa de acordo com os resultados obtidos no pós-teste de Competência Comunicativa.

This thesis is an analysis of some research undertaken with students in a unit on human sexuality. It is a critical account of an experiment with 'radical' pedagogy which deliberately forsakes the pessimistic determinism of social reproduction theory in education and assumes the fundamental optimism of resistance theory, wherein human actors are capable of penetrating oppressive ideology and practice and working towards emancipation and social change. The experiment is an attempt to implement radical pedagogy in a particular classroom, and the body of the thesis consists of a critique of data collected from participants' notes and transcriptions of video and audio-tapes of thirteen, two�hour class sessions. The first chapter of the thesis outlines the nature of a pedagogical style which could be described as counter�hegemonic, non-reproductive, or liberatory, and it specifies the elements of a 'radical' approach to classroom process and content, which is distinguished from a 'traditional' one. Subsequent chapters present a critical analysis of actual classroom 'content' and 'process', which is based on a study of reconstructed sessional data, and the final chapter discusses the factors which limited the 'success' of the experiment, and attempts to draw some conclusions about the liberatory possibilities of radical pedagogy.

Outstanding areas of ambiguity within our present understanding of the nature and behaviour of neutrinos warrant the construction of a dedicated future facility capable of investigating the likely parameter space for the theta 1,3 mixing angle, the Dirac CP violating phase and clarifying the neutrino mass hierarchy. A number of potential discovery venues have been proposed including the beta beam, superbeam and neutrino factory accelerator facilities. Of these, the neutrino factory significantly outperforms the others. A neutrino factory will deliver intense beams of 10^21 neutrinos per year, produced from muons decaying in storage rings. This specification, coupled with the constraints of the short muon lifetime warrant the inclusion of a novel cooling channel to reduce the phase space volume of the beam to fall within the acceptance of the acceleration system. Ionisation cooling is the only viable cooling technique with efficacy over the lifetime of the muon, however, it has yet to be demonstrated in practice. In a full cooling channel, a muon beam will traverse a periodic absorber and accelerator lattice consisting of low Z absorbers enclosed by focusing coils and accelerating radio-frequency cavities. Energy loss in the absorbers reduces both transverse and longitudinal momentum. The latter is restored by the accelerating cavities providing a net reduction in transverse momentum and consequently reducing the phase space volume of the muon beam. The Muon Ionisation Cooling Experiment (MICE), under construction at the ISIS synchrotron at Rutherford Appleton Laboratory seeks to provide both a first measurement and systematic study of ionisation cooling, demonstrated within the context of a single cell prototype of a cooling channel. The experiment will evolve incrementally toward its final configuration, with construction and scientific data taking schedules proceeding in parallel. The stated goal of MICE is to measure a fractional change in emittance of order 10% to an error of 1%. This thesis constitutes research into different aspects of MICE: design and implementation of the MICE configuration database, determination of the statistical errors and alignment tolerances associated with cooling measurements made using MICE, simulations and data analysis studying the performance of the luminosity monitor and a first analysis of MICE Step I data. A sophisticated information management solution based on a bi-temporal relational database and web service suite has been designed, implemented and tested. This system will enable the experiment to record geometry, calibration and cabling information in addition to beamline settings (including but not limited to magnet and target settings) and alarm handler limits. This information is essential both to provide an experimental context to the analysis user studying data at a later time and to experimenters seeking to reinstate previous settings. The database also allows corrections to be stored, for example to the geometry, whereby a later survey may clarify an incomplete description. The old and new geometries are both stored with reference to the same period of validity, indexed by the time they are added to the configuration database. This allows MICE users to recall both the best-known geometry of the experiment at a given time by default, as well as the history of what was known about the geometry as required. Such functionality is two dimensional in time, hence the choice of a bi-temporal database paradigm, enabling the collaboration to run new analyses with the most up to date knowledge of the experimental configuration and also repeat previous analyses which were based upon incomplete information. From Step III of MICE onwards, the phase space volume, or emittance, of the beam will be measured by two scintillating fibre trackers placed before and after the cooling cell. Since the two emittance measurements are made upon a similar sample of muons, the measurement errors are influenced by correlations. This thesis will show through an empirical approach that correlations act to reduce the statistical error by an order of magnitude. In order to meet its goals MICE must also quantify its systematic errors. A misalignment study is presented which investigates the sensitivity of the scintillating fibre trackers to translational and rotational misalignment. Tolerance limits of 1 mm and 0.3 mrad respectively allow MICE to meet the requirement that systematic errors due to misalignment of the trackers contribute no more than 10% of the total error. At present, MICE is in Step I of its development: building and commissioning a muon beamline which will be presented to a cooling channel in later stages of MICE. A luminosity monitor has been built and commissioned to provide a measurement of particle production from the target, normalise particle rate at all detectors and verify the physics models which will be used throughout the lifetime of MICE and onwards through to the development of a neutrino factory. Particle identification detectors have already been installed and allow the species of particles to be distinguished according to their time of flight. This has enabled a study of particle identification, particle momenta and simulated and experimental beam profiles at each time of flight detector. The widths of the beam profiles are sensitive to multiple scattering and magnetic effects, providing an opportunity to quantify the success of the simulations in modelling these behaviours. Such a comparison was also used to detect offsets in the beam centre position which can be caused by misalignments of the detectors or relative misalignments in magnet positions causing asymmetrical skew in the magnetic axis. These effects were quantified in this analysis. Particle identification combined with the earlier statistical analysis will be used to show that the number of muons required to meet the statistical requirements of MICE can be produced within a realistic time frame for each beam configuration considered.

Makerspaces oder FabLabs sind offene High-Tech-Werkstätten für innovative Menschen, neue Ideen und Do-It-Yourself-Projekte. Sie dienen der Exploration neuer, durchaus auch wissenschaftsrelevanter Techniken, dem Erfahrungsaustausch und der Vernetzung mit anderen Kreativen. Zur Grundausstattung gehören Werkzeuge wie 3D-Drucker, Lasercutter oder CNC-Fräsen, die moderne Produktionsverfahren allen zugänglich machen. So wird Schneiden, Sägen, Bohren und Elektronikbasteln so einfach wie das Drucken zuhause. Durch das Zusammentreffen von Computerfreaks, Designern und Bastlern mit spezifischem Wissen und besonderen Fähigkeiten entsteht ein interdisziplinärer Wissenspool, der in neue Forschungskonzepte und Produkte fließen kann. Wie auch bei Open Access ist ein weiteres Ziel, den offenen Zugang und die freie Weitergabe von Wissen zu fördern.

Muon beams of low emittance would deliver intense, well-characterised neutrino beams necessary to explicate the physics of flavour at a Neutrino Factory and for high-luminosity lepton-antilepton collisions at a multi- TeV muon collider. The International Muon Ionisation Cooling Experiment (MICE), based at the Rutherford Appleton Laboratory, aims to demonstrate ionisation cooling, the technique proposed to reduce the emittance of muon beams at such facilities. An ionisation cooling channel has been constructed. The muon beam traverses a low-Z absorber material, losing energy via ionisation. The phase space volume occupied by the beam is reduced, resulting in transverse cooling. This thesis presents two independent analyses accomplished through exploiting data obtained during the “Step IV” commissioning of MICE. Muons can decay within the cooling channel. The presence of electron contaminants within MICE will generate systematic uncertainties on the cooling measurement. The angular distribution of decay electrons is dependent upon the muon polarisation. It is, therefore, imperative to characterise the impact of depolariza- tion in the channel. Chapter 4 presents a unique measurement of the polarisation of the MICE muon beam at the downstream calorimeter. For an initially unpolarised muon beam a polarisation of: -0.021 ± 0.243 (stat.) ± 0.185 (sys.) ± 0.007 (depol.) ± 0.001 (det.) is obtained, appropriately identifying the polarisation of the beam at the point of decay, within acknowledged errors. MICE is devised to possess an on-axis magnetic field. It is paramount that misalignment in the cooling channel is characterised. Chapter 5 ascertains a measurement of the central Focus Coil’s transverse position using single particle transfer matrices. No misalignment of the Focus Coil’s magnetic axis, relative to the beam axis, is observed, within the limits of the analysis. This innovative technique can be employed by any multi-element accelerator system where particle co-ordinates are quantified upon entering and exiting a constituent magnet.
