PhDThis thesis considers actors as ‘manual philosophers’; it engages the proposition that acting can reveal aspects of existence and Being. In this sense, forms of acting that analyse and engage with lived experience of the world offer a phenomenological approach to the problem of Being. But rather than arrive at abstract, general conclusions about the human subject’s relationship to the world, at least some approaches to acting investigate the structures of experience through those experiences themselves in a lived, physical way. I begin with the troubled relationship between philosophy and theatre and briefly consider the history of attacks on actors. I suggest that at the heart of antitheatricality is what Jonas Barish (1981: 3) calls ‘ontological queasiness’: theatre poses a problem in the distinction between ‘what is’ and ‘what is not’. Turning to phenomenology as a particular way of doing philosophy that challenges any dualistic understanding of subjectivity, I reflect on Martin Heidegger’s Being and Time as a lens for viewing the process of performing and preparing for a role. Heidegger emphasises the intermeshed relationship between the human subject, Dasein (Being-there), and the world to the point that it is impossible to consider one without the other. I have chosen three of the most influential theatre and acting theorists of the twentieth century and examine how each uncovers aspects of existence that are presented in Heidegger’s phenomenology. Firstly, I consider Constantin Stanislavski’s ‘system’ which emphasises action for a purpose within an environment, the individual’s relationship to objects in the world and its involvement with other people who share the same type of Being in the world. Secondly, I examine Antonin Artaud’s conception of theatre that seeks to resist the structures of Being, the way the world is interpreted by others (the ‘They’) and the way that the world gets handed over to consciousness for the most part. In many respects, Artaud’s theatre is the embodiment of Anxiety, a world-revealing state where Being becomes apparent. Thirdly, I discuss Bertolt Brecht’s theatre practice as an attestation to authenticity (a truthful engagement with human existence as possibility) through the medium of performance. Brecht seeks to engage audiences in philosophical debate and change the world. Like Heidegger, Brecht also stresses the historical and temporal constitution of the human subject, whilst emphasising practicality in theatre making. By examining these approaches to performance as case studies, this thesis rethinks the notional intersection of philosophy and theatre, concentrating on process rather than literary analysis. This application of phenomenology is new in that it does not merely consider theatre analysis from an ‘ideal’ audience point of view (i.e. provide a phenomenology of theatre). By focusing on acting, I emphasise the development of artistic creation and becoming, and show how certain types of acting are phenomenological. The bold upshot here is a conception of philosophy that acknowledges various theatre practices as embodied forms of philosophical practice. Furthermore, theatre might well be thought of as phenomenological because it can be an investigation of Being firmly entrenched in practical action and performance. Conversely, philosophy is more than just words on a page; it is a performed activity. Actors can be considered manual philosophers in so far as they engage with the problem of Being not in mere abstraction but in the practical challenges of performance.

Full textAbstract:
From Aristotle’s theory of tragic katharsis to Brecht’s formulation of the Verfremdungseffekt, theorists of the theatre have long engaged with the question of what spectatorship entails. Such question has, directly or indirectly, extended to the investigation of acting. In the wake of Brecht’s critique of conventional theatre, emphasis has been put on the study of spectatorship from the point of view of its cultural determinants and its conscious cognitive aspects, while unconscious processes have been mostly ignored. In this thesis I take a psychoanalytic perspective to analyse theories of the theatre that have investigated the process of identification of the spectator or the actor with the character. According to psychoanalysis, mechanisms of unconscious identification, such as projection and introjection, are fundamental to psychic development and to the construction of the self. By analysing Aristotle’s theory of tragic katharsis through Freud’s theory of transference, I propose a new understanding of spectatorship as transference dynamic. I then conduct an in-depth enquiry into eighteenth-century theories of acting which lead up to Diderot’s Paradoxe sur le comédien. I investigate the paradox of the actor, in its fruitful tension between sensibility and understanding, from the perspective of Melanie Klein’s concept of unconscious phantasy and Bion’s theory of alpha-function. I hence interpret the art of the actor as the performing of alpha-function on the spectator’s unconscious emotions. The new insights afforded by a psychoanalytic perspective of spectating and acting illuminate the moral function of theatre and resolve some of the controversial points brought forward by various theorists, including Brecht and Rousseau. The moral function of theatre can be construed as a transpersonal process in which unconscious identifications between spectator and actor promote the development of a reflective view of the self.

Full textAbstract:
This report is intended to help arbitrate the unsettled matter of when in the course of their early cognitive development children first evidence some "theory-like" understanding of their own and others' mental lives. To this end, this study directly compared results obtained through the administration of two competing assessment procedures, each of which has been used to support conflicting claims regarding the earliest age at which children first evidence an understanding of the possibility of false beliefs.
A substantial body of recent research has contributed to a growing, but perhaps premature consensus that children under 4 years of age do not recognize the possibility of counterfactual beliefs in others and consequently lack any early theory of mind. Much of the evidence in support of this late-onset view is based upon the use of an "unexpected change" task developed by Wimmer and Perner (1983) in which children are asked to predict where an inadequately informed story character will search for an object. In contrast to these findings results obtained using a recently developed hide-and-seek task, which directly assessed children's abilities to generate misleading clues in order to produce a false-belief in another, offered strong support for a much earlier-onset position (Chandler, Fritz & Hala, in press). Despite strong methodologic reasons in favour of accepting the results of this investigation the possibility remained that the 3-year-olds in the Chandler et al. study were a special population that might also have succeeded in the unexpected change task had they been given it. To guard against this possibility the present study provided a within-subject comparison of both the unexpected change procedure and the newer hide-and-seek procedure based on the responses of 30 children ages 3.0, 3.5 and 4.0 years. A further test of false-belief understanding was provided by asking subjects to comment directly upon their opponent's belief based on subjects' own misleading actions. As predicted even young 3-year-olds demonstrated the ability to provide misleading clues to their opponent but when faced with the unexpected change task these youngest subjects performed poorly. When responding to the false-belief question based on their own deceptive actions, however, even these youngest subjects showed strong evidence of understanding the possibility of false beliefs in others.Arts, Faculty of

Full textAbstract:
this thesis, we study linear type-theories and their semantics. We present a general framework for such type-theories, and prove certain decidability properties of its equality. We also present intuitionistic linear logic and Milner's action calculi as instances of the framework, and use our results to show decidability of their respective equality judgements. Firstly, we motivate our development by giving a split-context logic and type-theory, called dual intuitionistic linear logic (DILL), which is equivalent at the level of term equality to the familiar type-theory derived from intuitionistic linear logic (ILL). We give a semantics for the type-theory DILL, and prove soundness and completeness for it; we can then deduce these results for the type-theory ILL by virtue of our translation. Secondly, we generalise DILL to obtain a general logic, type-theory and semantics based on an arbitrary set of operators, or general natural deduction rules. We again prove soundness and completeness results, augmented in this case by an initiality result. We introduce Milner's action calculi, and present example instances of our framework which are isomorphic to them. We extend this isomorphism to three significant higher-order variants of the action calculi, having functional properties, and compare the induced semantics for these action calculi with those given previously. Thirdly, motivated by these functional extensions, we define higher-order instances of our general framework, which are equipped with functional structure, proceeding as before to give logic, type-theory and semantics. We show that the logic and type-theory DILL arise as a higher-order instance of our general framework. We then define the higher-order extension of any instance of our framework, and use a Yoneda lemma argument to show that the obvious embedding from an instance into its higher-order extension is conservative. This has the corollary that the embeddings from the action calculi into the higher-order action calculi are all conservative, extending a result of Milner. Finally, we introduce relations, a syntax derived from proof-nets, for our general framework, and use them to show that certain instances of our framework, including some higher-order instances, have decidable equality judgements. This immediately shows that the equalities of DILL, ILL, the action calculi and the higher-order action calculi are decidable.

Full textAbstract:
The surface of animal cells is a thin layer composed of a lipid bilayer and a cytoskeleton. Cells control their shape dynamically by remodeling their cytoskeleton via active processes. In a first part, we consider the actomyosin cortex and its role in cytokinesis, the last stage of cell division. We formulate a viscous-active membrane mechanical theory of the cortical layer. The Lagrangian formulation of the theory is implemented numerically to study large cortical deformations during cytokinesis. We show that an equatorial band of myosin overactivity is sufficient to reproduce the formation and ingression of a cleavage furrow. We predict cytokinesis above a well-defined threshold of equatorial contractility and propose a physical explanation of the independence of cytokinesis duration on cell size in embryos. Scaling arguments are proposed as a simple interpretation of the numerical results and unveil a key mechanism: cytoplasmic incompressibility results in a competition between the furrow line tension and the cell poles surface tension. In the second part, we study the red-blood cell membrane and propose a model for its active fluctuations. We consider both the thermal fluctuations of the lipid bilayer and the chemical fluctuations of the spectrin skeleton anchoring to the lipid bilayer. The constant supply of ATP, by weakening this anchoring, is proposed to give rise to extra-fluctuations of the membrane. These non-equilibrium fluctuations violate the fluctuation-dissipation theorem, in agreement with experimental measurements, thereby exhibiting the living nature of the red-blood cellLa surface des cellules animales est composée d'une bicouche lipidique et d'un cytosquelette. Les cellules contrôlent leur forme en remodelant leur cytosquelette par des processus actifs. Nous considérons tout d'abord le cortex d'actomyosine et son rôle lors la cytocinèse, dernière étape de la division cellulaire. Nous formulons une théorie mécanique de membrane de la couche corticale active et visqueuse. La formulation Lagrangienne de la théorie est implémentée numériquement pour étudier la cytocinèse en régime de larges déformations. Nous montrons qu'une bande d'hyperactivité de la myosine à l'équateur de la cellule suffit à reproduire la formation et la contraction du sillon de division. Nous prédisons le succès de la cytocinèse au delà d'un certain seuil de contractilité équatoriale et proposons une explication physique de l'indépendance de la durée de contraction avec la taille d'un embryon. Des arguments d'échelle permettent d'interpréter les résultats numériques et révèlent un mécanisme clé: l'incompressibilité du cytoplasme induit une compétition entre la tension de ligne du sillon et la tension de surface aux pôles. Nous étudions ensuite la membrane du globule rouge et proposons un modèle pour ses fluctuations actives. Nous considérons à la fois les fluctuations thermiques de la membrane et les fluctuations chimiques de l'ancrage des filaments de spectrine dans la membrane. Un apport constant d'ATP, en affaiblissant cet ancrage, est la source de fluctuations supplémentaires dans la membrane. Ces fluctuations hors-équilibre violent le théorème de fluctuation-dissipation, en accord avec les résultats expérimentaux, signe que les globules rouges sont vivants

Full textAbstract:
During face-to-face meetings, humans use multimodal information, including verbal information, visual information, body language, facial expressions, and other non-verbal gestures. In contrast, during computer-mediated-communication (CMC), humans rely either on mono-modal information such as text-only, voice-only, or video-only or on bi-modal information by using audiovisual modalities such as video teleconferencing. Psychologically, the difference between the two lies in the level of the subjective experience of presence, where people perceive a reduced feeling of presence in the case of CMC. Despite the current advancements in CMC, it is still far from face-to-face communication, especially in terms of the experience of presence. This thesis aims to introduce new concepts, theories, and technologies for presence design where the core is actions for creating presence. Thus, the contribution of the thesis can be divided into a technical contribution and a knowledge contribution. Technically, this thesis details novel technologies for improving presence experience during mediated communication (video teleconferencing). The proposed technologies include action robots (including a telepresence mechatronic robot (TEBoT) and a face robot), embodied control techniques (head orientation modeling and virtual reality headset based collaboration), and face reconstruction/retrieval algorithms. The introduced technologies enable action possibilities and embodied interactions that improve the presence experience between the distantly located participants. The novel setups were put into real experimental scenarios, and the well-known social, spatial, and gaze related problems were analyzed. The developed technologies and the results of the experiments led to the knowledge contribution of this thesis. In terms of knowledge contribution, this thesis presents a more general theoretical conceptual framework for mediated communication technologies. This conceptual framework can guide telepresence researchers toward the development of appropriate technologies for mediated communication applications. Furthermore, this thesis also presents a novel strong concept – presence through actions - that brings in philosophical understandings for developing presence- related technologies. The strong concept - presence through actions is an intermediate-level knowledge that proposes a new way of creating and developing future 'presence artifacts'. Presence- through actions is an action-oriented phenomenological approach to presence that differs from traditional immersive presence approaches that are based (implicitly) on rationalist, internalist views.

Full textAbstract:
In this thesis we study the low-energy effective dynamics emerging from a class of F-theory compactifications in four and six dimensions. We also investigate six-dimensional supersymmetric quantum field theories with self-dual tensors, motivated by the problem of describing the long-wavelength regime of a stack of M5-branes in M-theory. These setups share interesting common features. They both constitute examples of intrinsically non-perturbative physics. On the one hand, in the context of F-theory the non-perturbative character is encoded in the geometric formulation of this class of string vacua, which allows the complexified string coupling to vary in space. On the other hand, the dynamics of a stack of multiple M5-branes flows in the infrared to a novel kind of superconformal field theories in six dimensions - commonly referred to as (2,0) theories - that are expected to possess no perturbative weakly coupled regime and have resisted a complete understanding so far. In particular, no Lagrangian description is known for these models. The strategy we employ to address these two problems is also analogous. A recurring Leitmotif of our work is a transdimensional treatment of the system under examination: in order to extract information about dynamics in $d$ dimensions we consider a (d-1)-dimensional setup. As far as F-theory compactifications are concerned, this is a consequence of the duality between M-theory and F-theory, which constitutes our main tool in the derivation of the effective action of F-theory compactifications. We apply it to six-dimensional F-theory vacua, obtained by taking the internal space to be an elliptically fibered Calabi-Yau threefold, but we also employ it to explore a novel kind of F-theory constructions in four dimensions based on manifolds with Spin(7) holonomy. With reference to six-dimensional (2,0) theories, the transdimensional character of our approach relies in the idea of studying these theories in five dimensions. Indeed, we propose a Lagrangian that is formulated in five dimensions but has the potential to capture the six-dimensional interactions of (2,0) theories. This investigation leads us to explore in closer detail the relation between physics in five and in six dimensions. One of the outcomes of our exploration is a general result for one-loop corrections to Chern-Simons couplings in five dimensions.

Full textAbstract:
The theories of gravity are one of the most important topics in theoretical physics and mathematical physics nowadays. The classical formulation of gravity uses the Hilbert-Einstein Lagrangian, which is a singular second-order Lagrangian; hence it requires a geometric theory for second-order field theories which leads to several difficulties. Another standard formulation is the Einstein-Palatini or Metric-Affine, which uses a singular first order Lagrangian.
Much work has been done with the aim of establishing the suitable geometrical structures for describing classical field theories. In particular, the multisymplectic formulation is the most general of all of them and, in recent years, some works have considered a multisymplectic approach to gravity. This formulation allows us to study and better understand several inherent characteristics of the models of gravity.
The aim of this thesis is to use the multisymplectic formulation for first and second-order field theories in order to obtain a complete covariant description of the Lagrangian and Hamiltonian formalisms for the Einstein-Hilbert and the Metric-Affine models, and explain their characteristics; in particular: order reduction, constraints, symmetries and gauge freedom.
Some properties of multisymplectic field theories have been developed in order to study the models. We have established the constraints generated by the projectability of the Poincaré-Cartan form. These constraints are related to the fact that the higher order velocities are strong gauge vector fields. The concept of gauge freedom for field theories also has been analyzed. We propose to use the term "gauge'' to refer to the non-regularity of the Poincaré-Cartan form. Therefore, the multiple solutions are characterized by two sources: the gauge related one, arising from gauge symmetries and related to the non-regularity; and the non-gauge related one, which arises exclusively from field theories.
We studied in detail two models of gravity: the Einstein-Hilbert model and the Metric-Affine (or Einstein-Palatini) model. In both cases, a covariant Hamiltonian multisymplectic formalism has been presented. In every situation, we find the final submanifold where solutions exist, and we explicitly write all semi-holonomic multivector fields solution of the field equations. The natural Lagrangian symmetries are presented aswell. Furthermore, we emphasize different aspects in each model:
The Einstein-Hilbert model is a singular second order field theory which, as a consequence of its non-regularity, it is equivalent to a regular first order theory. For this model we have presented the unified Lagrangian-Hamiltonian formalism. We have also considered the presence of energy-matter sources and we show how some relevant geometrical and physical characteristics of the theory depend on the source's type.
The Metric-Affine model is a singular first order field theory which has a gauge symmetry. We recover and study this gauge symmetry, showing that there are no more. The constraints of the system are presented and analysed. Using the gauge freedom and the constraints, we establish the geometric relation between the Einstein-Palatini and the Einstein-Hilbert models, including the relation between the holonomic solutions in both formalisms. We also present a Hamiltonian model involving only the connection which is equivalent to the Hamiltonian Metric-Affine formalism.Les teories de la gravetat són un dels temes més importants en física teòrica i física matemàtica avui en dia. La formulació clàssica de la gravetat utilitza el Lagrangià de Hilbert-Einstein, el qual és un Lagrangià singular de segon ordre; per tant requereix una teoria geomètrica per teories de camp de segon ordre, que comporten diverses dificultats. Una altra formulació estàndard és la d'Einstein-Palatini o Mètrica-Afí, la qual utilitza un Lagrangià singular de primer ordre. S'ha treballat molt per establir les estructures geomètriques adients per descriure teories de camps clàssiques. Particularment, la formulació multisimplèctica és la més general de totes i, recentment alguns treballs han considerat la gravetat des de un punt de vista multisimplèctic. Aquesta formulació ens permet estudiar i entendre millor diverses característiques inherents dels models gravitatoris. L'objectiu d'aquesta tesi és utilitzar la formulació multisimplèctica per a teories de camps de primer i segon ordre per obtenir una descripció covariant completa dels formalismes Lagrangià i Hamiltonià per als models d'Einstein-Hilbert i Mètrica-Afí, i explicar les seves característiques. Concretament: reducció de l'ordre, restriccions, simetries i llibertat gauge. Algunes propietats de les teories de camps multisimplèctiques han estat desenvolupades per estudiar els models. S'han establert les restriccions generades per la projectabilitat de la forma de Poincaré-Cartan. Aquestes restriccions tenen relació amb el fet que les velocitats d'ordre superior són camps vectorials gauge forts. El concepte de llibertat gauge per a teories de camps també ha estat analitzat. Es proposa la utilització del terme "gauge" per fer referència a la no regularitat de les formes de Poincaré-Cartan. Per tant, les múltiples solucions es caracteritzen a partir de dues fonts: la relativa al gauge, que està relacionada amb la no regularitat, i altres fonts no relacionades amb el gauge que són exclusives de teories de camps. S'ha estudiat en detall dos models de gravetat: el model d'Einstein-Hilbert i el de Mètrica-Afí (o Einstein-Palatinti). En ambdós casos s'ha presentat una formulació covariant multisimplèctica Hamiltoniana. En tots els casos trobem la subvarietat final on les solucions existeixen, i escrivim explícitament tots els camps multivectorials sem-holònoms solució de les equacions de camp. També presentem les simetries Lagrangianes naturals. A més emfatitzem aspectes diferents en cada model: El model d'Einstein-Hilbert és una teoria de camp singular de segon ordre, la qual, com a conseqüència de la seva no regularitat, és equivalent a una teoria regular de primer ordre. Per aquest model hem presentat el formalisme unificat Lagrangià-Hamiltonià. També hem considerat la presència de fonts d'energia-matèria i es mostra com algunes característiques físiques i geomètriques rellevants de la teoria depenen del tipus de font. El model Mètrica-Afí és una teoria de camps singular de primer ordre que té una simetria gauge. Es recupera i s'estudia aquesta simetria gauge mostrant que és única. Les lligadures del sistema són presentades i analitzades. Utilitzant la llibertat gauge i les lligadures, s'estableix la relació geomètrica entre els models d'Einstein-Palatini i d'Einstein-Hilbert, inclosa la relació entre les solucions holònomes en ambdós formalismes. També es presenta un model Hamiltonià, que conté únicament la connexió, equivalent al formalisme Mètrica-Afí Hamiltonià

La classe des actions approximativement transitives (at) a ete introduite par a. Connes et e. J. Woods a propos du probleme d'une caracterisation des facteurs qui sont des produits tensoriels infinis de facteurs de type i. La these est consacree a l'etude de ces actions et est composee de quatre chapitres. Le chapitre i presente des preliminaires. Le chapitre ii : on definit une propriete appelee rang un gauche (f. R. O. ) ; on montre qu'elle ne depend pas du choix d'une mesure dans la meme classe et qu'elle implique at. On demontre le theoreme suivant sur les actions induites : soit h un sous-groupe normal ferme d'un groupe localement compact separable g. Si l'action naturelle de g sur g/h et une action de h sur un espace de lebesgue sont f. R. O. , il en va de meme pour l'action induite de g. Si g est resoluble, la premiere condition est toujours vraie. Un theoreme analogue est aussi demontre pour les actions at, meme sans supposer que h soit normal. On obtient plusieurs corollaires interessants. Le chapitre iii : quelques criteres de la propriete at sont demontres. Un 1-cocycle double d'une action ergodique de type ii ou iii constitue du cocycle de radon et nikodym et d'un cocycle arbitraire est faiblement equivalente a un cocycle produit d'un odometre produit si et seulement si l'action double de mackey est at. Dans le cas de type ii, on peut meme trouver un cocycle produit cohomologue au cocycle de depart. Un exemple montre qu'il est necessaire de considerer les actions doubles de mackey. Le chapitre iv : on presente un exemple d'une action jointe de deux groupes g et z qui n'est pas isomorphe au produit des actions de g et z correspondantes et possede quelques proprietes inattendues.

Full textAbstract:
Action Theories are versatile and well-studied knowledge representation formalisms for modelling dynamic domains. However, traditional action theories allow only the specification of definite world knowledge, that is, universal rules for which there are no exceptions. When modelling a complex domain for which no complete knowledge can be obtained, axiomatisers face an unpleasant choice: either they cautiously restrict themselves to the available definite knowledge and live with a limited usefulness of the axiomatisation, or they bravely model some general, defeasible rules as definite knowledge and risk inconsistency in the case of an exception for such a rule.
This thesis presents a framework for default reasoning in action theories that overcomes these problems and offers useful default assumptions while retaining a correct treatment of default violations. The framework allows to extend action theories with defeasible statements that express how the domain usually behaves. Normality of the world is then assumed by default and can be used to conclude what holds in the domain under normal circumstances. In the case of an exception, the default assumption is retracted, whereby consistency of the domain axiomatisation is preserved.

The thesis makes use of the framework of action and life to consider four philosophical theories of mind, enunciated in the writings of Rene Descartes, David Hume, William James, and Thomas Nagel. Showing how each theory makes an appeal to action or life in order to attempt to provide a characterization of mind that is not too restrictive nor too lax is the concern of the extensive historical portion of the thesis. It is on the basis of the success or failure of these appeals to the mind's living experience of its own activity that the four theories are evaluated. By way of conclusion, the reprecussions of these successes and failures for the contemporary activity of philosophizing about mind are briefly examined.

This thesis deals with two topics in lattice field theories. In the first part we discuss aspects of renormalization group flow and non-perturbative improvement of actions for scalar theories regularized on a lattice. We construct a perfect action, an action which is free of lattice artifacts, for a given theory. It is shown how a good approximation to the perfect action - referred to as classically perfect - can be constructed based on a well-defined blocking scheme for the 0(3) non-linear o-model. We study the O(N) non-linear r-model in the large-N limit and derive analytically its perfect action. This action is applied to the 0(3) model on a square lattice. The Wolff cluster algorithm is used to simulate numerically the system. We perform scaling tests and discuss the scaling properties of the large-N inspired perfect action as opposed to the standard and the classically perfect action. In the second part we present a new formulation for a quantum field theory with Abelian gauge symmetry. A Hamiltonian is constructed on a four-dimensional Euclidean space-time lattice which is invariant under local transformations. The model is formulated as a 5-dimensional path integral of discrete variables. We argue that dimensional reduction will allow us to study the behavior of the standard compact U(1) gauge theory in 4-d. Based on the idea of the loop-cluster algorithm for quantum spins, we present the construction of a flux-cluster algorithm for the U(1) quantum link model for the spin-1/2 quantization of the electric flux. It is shown how improved estimators for Wilson loop expectation values can be defined. This is important because the Wilson loops are traditionally used to identify confining and Coulomb phases in gauge theories. Our study indicates that the spin-1/2 U(1) quantum link model is strongly coupled for all bare coupling values we examined.

Full textAbstract:
The occurrence of higher-derivative terms both in classical and in quantum theories can be problematic. In case of impossibility of eliminating them by performing an integration by parts they give rise, in fact, to multiple problems, like extra unphysical degrees of freedom, negative unbounded energies and pathological negative norm states called ghosts. The possibility of curing them comes from a procedure developed by Jaén, Llosa and Molina in a classical Hamiltonian framework. It is applied when these terms are introduced as perturbative corrections to a healthy leading order theory multiplied by a perturbative expansion parameter. We first review this method from the classical point of view, then generalize it for Field Theories and finally apply it to SUSY. It's indeed in the latter context that one has always had difficulties in treating certain operators, those whose explicit field expansions contained unusual terms, like second (or higher) derivatives of a dynamical field or derivatives of an auxiliary one.\par
As we'll show, the approach developed is able to cure these unmanageable and unjustifiable extra degrees of freedom, paving the way for the construction of a new range of supersymmetric theories.

Full textAbstract:
Les recherches en education furent longtemps orientees vers la decouverte de la "bonne methode" d'enseignement. Devant l'echec de ce courant et la vanite des visees prescriptives, nous proposons une nouvelle voie. Depuis quelques temps, nombre de disciplines des sciences humaines insistent sur la necessite de prendre en compte le contexte dans l'etude du fait educatif. A partir de l'approche systemique et du modele du systeme enseignement/apprentissage dit des "interactions en contexte", nous avons theorise le concept de contextualisation. La contextualisation designe l'ensemble des processus interactifs qui relient le sujet agissant et son contexte. Lors de son operationnalisation, nous n'avons retenu que la dimension spatiale du concept de contextualisation. Nous proposons une kaleidoscopie des espaces d'enseignement, conjuguant des lectures geographiques, sociologiques, semiologiques et psycho-sociales des interactions de l'enseignant et de ces espaces. L'organisation des elements descriptifs nous a permis de proposer deux pistes explicatives: "l'hexispedagogique" et "le potentiel energetique de l'action de l'enseignant". La validation s'est effectuee en deux temps. Nous avons tout d'abord montre que les deux pistes entraient en resonance et attestaient par la-meme de l'unicite du concept. Nous avons ensuite evalue leurs capacites heuristiques a l'aune d'une etude des pratiques d'enseignement de la lecture au cp. Enfin, nous avons mis le concept en perspective en proposant quelques elements d'une theorie de l'action enseignante, la contextualis-action. Cette theorie defend l'idee que l'action de l'enseignant ne peut se reduire ni a sa planification (son avant) ni a son projet (son apres). Le "pendant" de l'action, de par sa temporalite lineaire et de par les processus de contextualisation, garde des prerogatives qui lui sont specifiquesFor un long time researches in education have been heading towards the discovery of "the right method" of teaching. This, coming to a failure and the prescriptive scopes revealing vain, we are suggesting a new way. For some time, a number of subjects in human sciences are putting a stress on the necessity of taking into account the background in the study of the teaching process. Starting from the teaching/training so-called "interactions in context" we have theorized the concept of contextualisation. Contextualisation is the name for all the interactive process which connect the acting person to his/or her context. While operating it we have only retainde the spatial dimension of the concept of contextualisation. We are proposing a kaleidoscopy of the teaching spheres combining geographic, sociologic, semiologic and psycho-social approaches of the interactions of the teacher and these spheres. The organisation of the descriptive elements has enabled us to suggest two possible explanations: "the pedagogic hexis" and the "energetic potential of the teacher's action". There has been two phases in the authentication. We have first shown that both interpretations were in harmony, which testified the uniqueness of the concept. We have then assessed their heuristic capacities which the measure of the teaching practises in reading in the first class of infant school. Finally, we have brought the concept to the fore by suggesting a few elements of the theory of the teaching action, the contextualis-action. The theory supports the idea that the teacher's action can be reduced neither to its planification (its "before") neither to its project (its "after"). The "during" of the action, because of its linear temporality on the one hand and to the processes of contextualisation on the other hand, keeps the prerogatives which are its own

Full textAbstract:
Many companies around the world have implemented Six Sigma as a problem solving methodology especially useful for dealing with recurring problems in business processes. Since the 1980s when it was developed at Motorola, many companies have tried to implement Six Sigma to fit their own company’s culture and goals. This thesis presents a longitudinal case study describing the evolution of ‘Six Sigma Management’ at Siemens in Sweden. The success of the programme was to a large degree built on previous failures, confirming Juran’s old saying ‘Failure is a gold mine’. From the case study, success factors for implementing Six Sigma at Siemens are identified and compared to those given in the literature. Some of the most critical success factors identified at Siemens had not been mentioned as such in the literature before. The main conclusion of the study is that, in order to succeed and get sustainable results from a Six Sigma programme, Six Sigma should be integrated with Process Management, instead of just running Six Sigma as a separate initiative in an organisation. Furthermore, the thesis includes papers presenting methods and tools to be used in a Six Sigma programme or in Six Sigma projects. They deal with: how to identify suitable Six Sigma projects, how to select which Six Sigma methodology to use, how to find hidden misunderstandings between people from different knowledge domains, and how to simulate the impact of improvements to iterative processes. All these methods and tools have been developed and tested at Siemens. This has been an action research project, where the author has been employed by the company under investigation for eleven years and has actively influenced the changes in the company based on knowledge gained at the company as well as on research studies conducted at universities. In action research the change initiative under investigation is conducted and analysed in a single context. The readers are invited to draw their own conclusions on the applicability of the results to their own specific cases. In addition to this, some conclusions derived using analytical generalisation, applicable to a more general case, are presented in the thesis.Defended att Chalmers University of Technolgy in 2007.

Full textAbstract:
In this dissertation, we investigate the relationship between visual attention and eye movement programming mechanisms in the brain. As a first step in this investigation, we demonstrate a link between microsaccades, or tiny eye movements that occur during periods of fixation, and covert attention shifts. Specifically, we employ psychophysical tasks that involve covert spatial attention shifts to peripheral cues, and we correlate the time courses of microsaccade occurrences in these tasks with the time courses of attention shifts, as revealed by the effects of these shifts on behavioral performance. Our results suggest that microsaccades, rather than being randomly distributed, have directions that are directly correlated with the directions of covert attention shifts. These results therefore suggest that microsaccades occur because of subliminal activation of the oculomotor system by covert attention.Besides providing a plausible explanation for much of the known phenomenology associated with microsaccades, the above link between microsaccades and covert attention means that the first may be used to track the latter. We demonstrate an example of such tracking by using microsaccades as a psychophysical tool to analyze the patterns of covert attention shifts that take place in typical visual tasks. In addition to revealing expected covert attention shifts in our tasks, microsaccade analysis reveals shifts that were previously unreported, including ones that are tightly synchronized with manual response execution. This analysis also shows that the patterns of attention shifts to task-relevant stimuli that are observed in visual tasks are identical whether overt saccades are allowed during task execution or not.
The above results lead to an investigation of the implications of overt and covert spatial attention shifts on feature processing. We present a post-motor theory of attention whose main thesis is that feature salience is modified in anticipation of the sensory consequences of a motor act, even if this act is eventually suppressed. We provide psychophysical evidence for such salience modification and show that a spatial attention shift to a location gives rise to a feature-based attention shift to the features at that location. We also show that such a feature-based attention shift outlasts a saccade and therefore aids the visual system in handling the consequences of such a saccade on target appearance.

Full textAbstract:
It is widely acknowledged that an agent is doing A intentionally only if she knows she is doing A. It has proved difficult, however, to reconcile two natural thoughts about this knowledge. On the one hand, the agent seems to know what she is doing immediately, simply by doing it. Her knowledge seems to rely upon no evidence, and indeed to rest upon no specifiable epistemic basis at all. On the other hand, the agent can be wrong about what she is doing; she is fallible. The difficulty is to see how an agent can be wrong about her action if her knowledge of it is immediate. My dissertation provides an account of the agent’s knowledge of her own actions that reconciles these natural, but apparently conflicting thoughts. In the face of this difficulty, many philosophers distinguish two objects of knowledge in action: the object of immediate knowledge, which is supposed to be something interior, and what the agent actually does, which is known only mediately. I argue that this two-factor framework is unacceptable, since it cannot account for the insight which motivated the study of intentional action via the agent’s knowledge of these actions: that it is in virtue of this specific way of knowing that the agent is the agent of her intentional actions. Instead, I defend a view on which acting intentionally itself, with no need for further epistemic work, is a way of knowing what actually happens. This account of knowledge in action also allows me to clarify how this knowledge is necessarily related to our capacity for agency. I argue that the rational capacities that are drawn on in figuring out what to do here and now are the very source of both the action’s taking place, and the agent’s knowledge of her actions without evidence. Since the agent’s knowledge is the result of the very same reasoning that brings about the action, it is practical, and the agent’s having it is the mark of her practical rationality at work and her being the knowingly efficacious author of the action.Philosophy

This study reviews English teaching for second grader pupils in Finland. It focuses on the teacher’s role in children’s language learning and meaning making and the execution of sociocultural and ecological learning theories in an English classroom. In addition to sociocultural and ecological learning theories, the theoretical framework is based on earlier studies on language teaching and learning in a classroom setting and the national curriculum. The study is a case study conducted in an elementary school. The data was collected by observing an English lesson and interviewing the teacher. Three themes emerged in the analysis of the findings: learning through play, meaning making through multimodal resources, and guiding and providing affordances. The first two themes involve the methods and materials the teacher employs in teaching, and the last one reviews her role in the English lesson. The study sheds light on how the sociocultural and ecological learning theories and the national curriculum are visible in the three aspects found in the studyTässä tutkimuksessa tarkastellaan englannin opettamista toisen luokan oppilaille.

Full textAbstract:
Traditionally, consistency is the only criterion for the quality of a theory in logic-based approaches to reasoning about actions. This work goes beyond that and contributes to the meta-theory of actions by investigating what other properties a good domain description should satisfy. Having Propositional Dynamic Logic (PDL) as background, we state some meta-theoretical postulates concerning this sore spot. When all postulates are satisfied, we call the action theory modular. We point out the problems that arise when the postulates about modularity are violated, and propose algorithmic checks that can help the designer of an action theory to overcome them. Besides being easier to understand and more elaboration tolerant in McCarthy's sense, modular theories
have interesting computational properties. Moreover, we also propose a framework for updating domain descriptions and show the importance modularity has in action theory change.

This thesis consists of an introduction, a summary and 7 papers. The papers are devoted to problems in ergodic theory, equidistribution on compact manifolds and random walks on groups. In Papers A and B, we generalize two classical ergodic theorems for actions of abelian groups. The main result is a generalization of Kingman’s subadditive ergodic theorem to ergodic actions of the group Zd. In Papers C,D and E, we consider equidistribution problems on nilmanifolds. In Paper C we study the asymptotic behavior of dilations of probability measures on nilmanifolds, supported on singular sets, and prove, under some technical assumptions, effective convergences to Haar measure. In Paper D, we give a new geometric proof of an old result by Koksma on almost sure equidistribution of expansive sequences. In paper E we give necessary and sufficient conditions on a probability measure on a homogeneous Riemannian manifold to be non–atomic. Papers F and G are concerned with the asymptotic behavior of random walks on groups. In Paper F we consider homogeneous random walks on Gromov hyperbolic groups and establish a central limit theorem for random walks satisfying some technical moment conditions. Paper G is devoted to certain Bernoulli convolutions and the regularity of their value distributions.QC 20100705

Full textAbstract:
This thesis explores two problems: (1) how early childhood teachers can manage professional development and change in their own settings, and (2) how to create a thesis. Both facets of the thesis emerge from the professional development in Active Movement that the teachers and I co-constructed at our early childhood centre between April 2005 and June 2006. This thesis sets out to test the main idea that having a theory of change for teachers' professional development can help teachers negotiate complex change and craft their own professional development solutions. It uses stories as a key facet of its methodology and presents stories of professional development and change related to five inter-weaving learning journeys. The learning journeys relate to (1) my learning journeys as a professional development coordinator and (2) as a researcher, (3) the overall learning journeys and (4) & (5) teachers' collective learning journeys to implement two different but related practices in Active Movement. The stories provide a range of professional development solutions and change at individual and collective levels from which different theories of change can be derived. From these stories, I identify three theories of change as well as the complex changes we negotiated and the professional development solutions we crafted. In identifying the theories of change, the complex changes and the professional development solutions, this thesis supports the main idea and argues that teachers can develop a theory of change to manage professional development and change in their own settings. This thesis argues that a theory of change is a set of strategies that address the local conditions. It suggests that the process of developing a theory of change can include articulating local conditions and creating strategies that support and guide the change in ways that address these local conditions. It also suggests that recognising what counts as local conditions and strategies can help teachers develop their own theories of change. In creating the strategies to support the change effort, it is important to identify the purpose of the strategies, their underlying values and relationships, and the day-to-day realities that constrain the change effort. At the same time, it is important to identify how different strategies inter-relate to help us manage the tensions that can arise from these relationships. This thesis argues that theories of change can include multiple and embedded theories of change, that we can create theories of change as plans or explanations of change or as dynamic theories of change that emerge from the inter-play between plans and explanations. This thesis also argues that there are different ways to articulate our theories of change and that there are limits to the extent to which we can or should articulate them. It also argues that the theories of change we create and use for our change efforts depend on the nature of the change. A theory of change that embodies the process of emergence is useful for managing professional development and change efforts that have a high degree of complexity and uncertainty and whose end goals are initially unknown. This thesis also suggests that creating the role of a professional development or change coordinator can help centres manage the knowledge used and created in the professional development or change effort in ways that benefit individuals, groups and the centre. This thesis also argues that (1) the thesis investigation is my personal professional development and represents my learning journeys to create a thesis, (2) the thesis report constitutes a theory of change for the thesis investigation, and (3) the thesis is experimental in the way that it is reported. This thesis proposes other possible investigations related to the idea of theories of change; (1) to develop an Active Movement community of practice within the wider early childhood sector, and (2) to investigate the role of theories of change in everyday teaching and learning. Finally, it uses the notion of value creation to suggest ways to create added value for the teachers and the Centre, for Sport and Recreation New Zealand and for myself.

Full textAbstract:
H. Ibisch a construit un espace fibre universel e(f;g)b(f;g) des (;g)-fibres f-libres, pour un groupe topologique g, un groupe de lie compact et une famille f de sous-groupes de. L'objectif central de cette these est d'etablir un theoreme de completion pour la cohomologie equivariante du classifiant b(f;g). Le chapitre 1 est consacre a la theorie generale des (;g)-fibres. Dans les chapitres 3 et 4, on donne une construction et une caracterisation homotopique de l'espace classifiant. Le premier resultat de ce travail se resume dans les theoremes de scindage obtenus dans le chapitre 5. Sous les hypotheses du deuxieme theoreme de scindage, et si g est un groupe topologique compact tel que, pour tout n, k#*(b#ng) soit un groupe de type fini, on etablit dans le chapitre 9 une suite exacte: 0lim#1k#*#(b#n(f;g))k##*(b(f;g))lim#0k##*(b#ng)#f0, dont le lim#1 s'annule si g est en plus un groupe de lie; k##*(b#ng)#f designe la completion par rapport a la topologie de jackowski. Comme la composante de base de l'espace classifiant est l'espace z(;g) des -cocycles elementaires, on remplace au chapitre 7 la topologie de jackowski par une nouvelle topologie f-adique cocyclique, obtenue par l'utilisation de k##*(z(;g)) a la place de l'anneau des representations r(). Dans ce chapitre, un theoreme de reduction est demontre. Comme corollaire, on obtient un isomorphisme entre pro-anneaux, moyennant des conditions sur la cohomologie equivariante, conditions dont la verification pour la k-theorie equivariante est l'objet du chapitre 8. La demonstration du theoreme de completion suivant est donnee dans le chapitre 9: soit x un -espace compact, muni d'un (;g)-cocycle elementaire , et tel que k##*(x) soit de type fini sur k##*(z(;g)), pour tout. Soit f une famille de sous-groupes de. On munit k##*(x) de la topologie f-adique cocyclique a l'aide de. Alors, la projection (xg)##ge(f;g)x induit un isomorphisme k##*((xg)##ge(f;g)k##*(x)#f, ou #f designe la completion par rapport a la topologie f-adique cocyclique

Full textAbstract:
A large number of studies show that educators are exposed to workloads that result particularly in stress. According to Olivier and Venter (2003), stress is considered to be the main factor contributing to job-related illnesses, early retirement, job dissatisfaction and absenteeism. Teaching, has without a doubt become a more demanding and stressful job. The lack of discipline in schools, abolishment of corporal punishment, large pupilteacher ratios and a new curriculum approach all contribute to raising the stress levels of teachers (Ngidi &
Sibaya, 2002). Stanton, Bachiochi, Robie, Perez and Smith (2002 cited in Brewer &
McMahan-Landers, 2003) is of the view that job stress is an antecedent of job satisfaction but the two constructs have been treated as related, yet they are different. The aim of this study is to determine the relationship between stress levels and job satisfaction amongst high school educators in De Aar as well as to
determine whether biographical variables (namely, gender, age, tenure, marital status and number of children) have an impact on job satisfaction and stress levels. The researcher hopes that
the findings would give the Department of Education in the Northern Cape an idea of the stress levels and job satisfaction experienced by high school educators in De Aar so that interventions can be implemented to issues proactively. The sample consisted of 86 educators employed at four high schools in De Aar. A biographical questionnaire, the Job Satisfaction Survey (JSS) and Stress Diagnostic Survey (SDS) were administered to assess respondents&rsquo
stress and job satisfaction levels. Informed consent was obtained from the various participants and anonymity of participation was ensured. Statistical analyses included inferential (Pearson&rsquo
s Product Moment Correlation Coefficient, Analysis of Variance &
T-Tests) as well as descriptive statistics. The results of the study
indicate that there is a statistically significant, inverse relationship between stress levels and job satisfaction amongst high school educators in De Aar. Furthermore, the results indicate that there
are statistically significant differences in stress levels as well as job satisfaction of high school educators on the basis of their biographical characteristics. The chapter concludes with presenting limitations of the study and putting forth recommendations for future research.

Full textAbstract:
L'objet de cette etude est de considerer le modele d'arbitrage dans l'environnement international; ceci afin de donner une alternative aux modeles internationaux d'equilibre des actifs financiers. Dans une premiere approche, nous avons mis en evidence que la relation fondamentale du modele d'arbitrage n'est pas exactement verifiee. Cependant, et malgre certaines critiques du modele d'arbitrage, celui-ci est coherent sur le plan theorique et de plus, il est falsifiable. Nous avons alors realise une analyse empirique de ce modele sur les echantillons d'actions de dix pays. Ce test indique que le modele est rejete dans quatre pays. Nous proposons ensuite une extension du modele d'arbitrage au cadre international. Dans ce modele international, des facteurs lies aux differents taux de change apparaissent en plus des facteurs traditionnels, et ces nouveaux facteurs sont apprecies. Des relations concernant les taux de change et les primes de risque sont alors developpees a partir de ce modele qu'une confrontation empirique ne nous a pas permis de rejeter. Deux a quatre primes de risque sont appreciees selon l'echantillon considere. Enfin, dans cette partie, est etablie une definition de l'integration financiere. Nos tests indiquent alors que le marche mondial n'est pas integre. En dernier lieu, nous avons tente d'expliquer les differents facteurs influencant les rentabilites des actifs financiers. .The purpose of this work is to extend the arbitrage pricing theory in the international context, to provide a fruitful alternative to the international asset pricing models. First of all, we show the arbitrage pricing equation is not exactly verified. However, and in spite of some problems, the model is theoritically coherent, and it is testable. Thus, we have carried out an empirical analysis of this model with samples of ten countries. This test rejects the model for four countries. In a second part, we propose an international version of the arbitrage pricing theory. In this international model, new factors reflect return translation in an other currency and these factors are appreciated. The relation between factors coefficients when measured in different currencies has been investigated, as well as the pricing of the forward exchange rates which depends on the covariance of the currency fluctuation with the same common factors. A test of the international model with two international sample indicates that two to four risk premia are not null, consequently, the model is not rejected. Thus, it seemed interesting to perform an empirical analysis of the financial integration in the theorical framework of this model. Our conclusion is that the world capital market is not integrated. At last, a tentative of economic interpretation of factors is realized. .

Full textAbstract:
Automated planning as a satisfiability problem is a method developed in theearly nineties. It has some known disadvantages, such as its inefficient encod-ing of numbers. The field of Satisfiability Modulo Teories tries to connectalready established solvers for e.g. linear constraints into SAT-solvers in orderto make reasoning about numerical values more efficient. This thesis combines planning as satisfiability and SMT to perform efficientreasoning about actions that occupy realistic time in Temporal Action Logic,a formalism developed at Linköping University for reasoning about action andchange.
