Nous entendons, dans ce mémoire, préciser le sens d'actus essendi par l’analyse de l’emploi du terme par Thomas d’Aquin. Bien que la notion d’acte d’être soit sousjacente à nombre de développements philosophiques et théologiques de l’Aquinate, elle n’est considérée pour elle-même dans aucun texte du corpus thomasien. En exposant le cadre théorique des onze unités textuelles dans lesquelles on retrouve nommément l’expression, nous explicitons les distinctions qu’opère Thomas entre l’acte d’être et les notions ontologiques corrélatives (étant, quiddité, être du jugement prédicatif et être commun). Si « actus essendi » désigne en premier lieu un principe constitutif de l’étant, il peut encore désigner le terme abstrait correspondant à cette perfection de l’étant. L’acte d’être est ainsi ce par quoi l’étant est étant; il est cependant, au plan ontologique, propre à chaque étant singulier tandis que, au plan conceptuel, le même terme exprime ce qui est commun à tous les étants. Une traduction des extraits du Scriptum super Sententiis, des Quæstiones de quolibet, de la Summa Theologiæ, des Quæstiones disputatæ De potentia, de l’Expositio libri De hebdomadibus et de la Expositio libri Metaphysicæ a été produite pour les fins de cette étude. / In this paper, we intend to precise the meaning of actus essendi by analyzing how Thomas Aquinas uses this term. If the notion of the act of being underlies a number of Aquinas’ philosophical and theological developments, it is not treated in itself in any of his writings. By exposing the theoretical framework of the eleven textual units in which the expression namely appears, we explicate how he distinguishes between the act of being and the correlative ontological notions (the being, the essence, the predicamental judgment being and common being). If « actus essendi » first designates a constitutive principle of being, it can also designate the corresponding abstract term of this perfection of being. The act of being is that by which being is being; however, it belongs, at the ontological level, to each particular being whereas at the conceptual level, the same term expresses that which is common to all beings. Extracts of the following texts have been translated in French for this purpose: Scriptum super Sententiis, Quæstiones de quolibet, Summa Theologiæ, Quæstiones disputatæ De potentia, Expositio libri De hebdomadibus and the Sententia libri Metaphysicæ.

Summaries in Afrikaans and English / Die term "volkspoesie" is reeds in die agtiende eeu deur Johann Gottfried Herder gebruik. Dit kom steeds in Europese tale soos Nederlands en Dui ts voor en word oak in Afrikaans gebruik. Belangstelling in die genre word in twee verskillende vakgebiede aangetref: die volkskunde en die letterkunde. Volkspoesie is poesie wat deur 'n individu geskep word, maar soveel aanklank vind by die "gewone publiek" dat hulle dit as 11volksbesit 11 aanvaar en mondel ing oordra. Die oorspronklike skepper raak dus vergete, die kunswerk bestaan anoniem voort en variante ontstaan. Volkspoesie het verskeie verskyningsvorme soos die volkslied( jie), die ballade, rympies en raaisels. Eiesoortige kenmerke is: spontaneiteit, eenvoud, die irrasionele. Alhoewel volkspoesie oor "landsgrense11 heen kan swerf, is bepaalde vorme daarvan dikwels streekgebonde. Nieteenstaande sy bevraagtekening van die term in die vyftigerjare het N.P. van Wyk Louw dit ook self gebruik. Sy gedigreeks 11 Klipwerk uit Nuwe verse (1954) het 'n nuwe belangstelling in volkspoesie gewek. Later het hy die reeks bestempel as 'n "soort volkspoesie wat hy doelbewus wou skep: volksversagtige" gedigte, gebind aan die digter se jeugwereld. D.J. Opperman het in sy proefskrif van 1953 ook ender meer 'n belangstelling in volkspoesie geopenbaar en in 1962 gewys op die volkse in moderne Afrikaanse digkuns. Sy laaste digbundel, Kamas uit 'n bamboesstok ( 1979), word as 'n volksboek met volkspoesie-eienskappe aangebied. Die vorm en eienskappe van volkspoesie vind neerslag in beide Van Wyk Louw en Opperman se werk. Aanvanklik skryf Van Wyk Louw heelwat volksversagtige gedigte en later gebruik hy ook volksballade-eienskappe in sy ballades. Ook in Tristia (1962) kom eienskappe van volksliedjies en rympies voor. Opperman verwerk meermale bestaande volksliedjies en -rympies in sy poesie en gebruik dit betekenisverruimend as verwysingsveld. Die twee digters se belangstelling in volkspoesie het gelei tot 'n verdere ontginning van die "volkse" vers in Afrikaans, onder andere deur digters soos Boerneef, Adam Small en Breyten Breytenbach. Volkskundige navorsing deur P.W. Grobbelaar en andere het in die moderne tyd ook die aandag op hierdie onderwerp gevestig. In die tagtigerjare is mondelinge Afrikaanse poesie selfs deur swartmense in hulle politieke stryd gebruik! / The term "folk-poetry" had already been used by Johann Gottfried Herder in the eighteenth century. It has ever since prevailed in European languages such as Dutch and German and is also found in Afrikaans. Interest in this genre occurs in two different fields of study: folklore and literature. "Folk-poetry" is poetry created by the individual and accepted by the "general public" to a large extent. Therefore it is acknowledged as common property and passed on by word of mouth. The original creator is thus forgotten, the work of art prevails anonymously and different versions come into being. "Folkpoetry" appears in a variety of forms: the folk-song( s), the ballad, rhymes and riddles. Particular characteristics are: spontaneousness, simplicity, the irrational. Although "folkpoetry" may cross "national borders", some forms are often regional. Despite his questioning the term in the fifties, N.P. van Wyk Louw used it himself. His poetry series "Klipwerk" from Nuwe verse (1954) gave rise to a new interest in ''folk-poetry". He afterwards labelled the series as "a kind of folk-poetry" which he deliberately wanted to create: "folksy" poems, relating to the world of the poet's youth. In his 1953 thesis D.J. Opperman also showed amongst others an interest in "folk-poetry" and in 1962 pointed out the "folksy" identity in contemporary Afrikaans poetry. His last anthology, Kamas uit 'n bamboesstok (1979), is presented as a folk book with "folk-poetry" characteristics. The form and characteristics of "folk-poetry" are embedded in both Van Wyk Louw's and Opperman's work. Initially Van Wyk Louw wrote quite a number of "folksy" poems and afterwards also used folk-ballad characteristics in the ballads he wrote. Characteristics of folk-songs and rhymes also occur in Tristia (1962). Opperman adapts existing folk-songs and rhymes in his poetry and uses it as framework to broaden the meaning. These two poets' interest in "folk-poetry" resulted in further exploration of the "folksy" verse in Afrikaans, among others by poets like Boerneef, Adam Small and Breyten Breytenbach. Folk research by P.W. Grobbelaar and others focused attention on this subject. In the eighties even blacks used oral Afrikaans poetry in their political struggle! / Afrikaans and Theory of Literature / D. Lit. et Phil. (Afrikaans)

Att designa mjukvaruapplikationer med en viss struktur kan ofta framhäva efterfrågade egenskaper. För att välja rätt arkitektur behövs ofta övervägningar, och ibland till och med kompromisser, göras om applikationens planerade karaktär. Det är ofta bra att i detta stadie ha en klar bild om vilka attribut en applikation önskas ha. Ett av de viktigare attributen på sikt är skalbarhet. Kunskapen om olika arkitekturers skalbarhet spelar en definitiv roll i designfasen, vilket avgör hur en applikation senare skalas. På senare år har mikrotjänst-arkitektur blivit ett populärt sätt att bygga mjukvara på där den höga skalbarheten sägs vara en bidragande faktor. Detta arbete har till syfte att undersöka skalbarheten hos mikrotjänst-arkitektur i förhållande till monolitisk arkitektur och visa hur detta kvalitetsattribut påverkas när en transformering från en monolit till en mikrotjänst-arkitektur görs. Arbetet har valt att utgå ifrån en existerande modul i en E-handelsplattform med öppen källkod. Modulen som transformerades till en mikrotjänst, skalades horisontellt för respektive arkitektur och applikations-version. Vid användandet av lämpliga verktyg, såsom Docker, visar resultatet att horisontell skalbarhet finns i högre grad hos mikrotjänst-arkitekturen och fortsätter därefter vara hög. Skalning av mikrotjänster kan göras med en högre precision av det som önskas förändras. Detta står i kontrast till den monolitiska strukturen, där skalning begränsas av prestandan av den miljö där mjukvaruapplikationen körs. Efter transformationen till en mikrotjänst-arkitektur ökade skalbarheten, då skalningsmetoden gjordes med mer finkornighet och isolering av den utvalda modulen. För att individuellt skala den monolitiska modulen horisontellt behövdes förändringen göras virtuellt med hjälp av bakgrundsprocesser. Denna lösning visar sig vara en indirekt skalning av hela den monolitiska strukturen. Utöver horisontell skalbarhet fokuserar utvärderingen av resultatet på kvalitativa attribut i form av simplicitet, autonomi och modularitet. / In designing software applications, a chosen structure can often accentuate desired properties. To choose the correct architecture, one must often do considerations and sometimes even compromises, about the intended characteristics of the application. In that stage it is often well motivated to have a clear picture about which attributes the application shall possess. Over time, one of the most important attributes is scalability. The knowledge about the scalability of different architectures could play a crucial part in the design phase, determining how an application is scaled in the future. In recent years Microservice Architecture has been a popular way of building software and its high scalability is said to be a contributing factor. This work has the purpose of examine the scalability of microservice architecture relative to the monolithic architecture and how this quality attribute is affected after a transformation is done from a monolith to a microservice system. This work is based on an existing module from an open source E-commerce platform. The module was first transformed into a working microservice, then both architectures was horizontally scaled. Using suitable tools such as Docker, the result of this work shows that horizontal scalability exists in a high degree within the microservice architecture and continues being high there after. Scaling of microservices can be done with higher precision of what are to be changed. This stands in relation to the monolithic approach where scaling is limited to the performance of the environment where the software application is running. The transformation to a microservice architecture resulted in an increase of scalability. The scaling method was more fined-grained and isolated to the selected module. In contrast, individual horizontal scaling of the monolithic module was required to be done virtually with background processes. This concluded in an indirect scaling of the whole structure of the monolith. Besides horizontal scalability, the evaluation is focused on the system quality attributes of simplicity, autonomy and modularity.

Deep ecology is the field of environmental ethics, which seeks to change human values and attitudes that would lead to the solution to environmental problems. The aim of this thesis is to confront the selected propositions which deep ecology include (overpopulation, economic growth, decentralization, ethics of voluntary simplicity and biodiversity) with views of other authors and to seek answers to the ethical and social issues associated with them.

2 Abstract In this text, we are asking if it is possible to think the 'psychedelic' without labelling it as 'different', 'imaginary', 'fantastic' or 'unreal', and without thinking it as a particular experiential region belonging specifically to human experience. By first thinking 'experience', we are then attempting to relate the psychedelic experience to human experience considered in the simple joining of its basic dimensions, and to think both of these experiential modalities through the same motives. If we think 'experience' as opening itself through its boundaries, which limit and thus open the dimensions through which the fundamental relation of presencing and apprehension plays, then we can think the psychedelic using the concept of 'layer' derived from the concept of 'boundary'. We first think the phenomena of transparency of time, of transparent attunement and of transparent clarity, which belong to human experience in its simplicity. We then think the phenomenon of disjoining of the basic dimensions of human experience, which takes us from human experience in its simplicity, through strangeness, towards the psychedelic. Lastly, we think the phenomenon of permeating, taking us to the simply joined or disjoined dimensions of human and non-human experience being played out in their layeredness...

S’efforcer d’être simple, telle est l’ambition constante qui anime Jules Renard. Contraint à la simplicité par la pauvreté de son imagination, qui le conduit à privilégier la « chose vue » et à puiser à la source étroite du quotidien vécu, il ne la subit pas pour autant, mais fait de l’effacement et de la réduction le cœur de son art littéraire. La première partie de la thèse envisage le questionnement théorique et esthétique de l’écrivain dans le champ littéraire de la fin de siècle. Si Renard hérite en partie des modèles classique et réaliste, sa simplicité est surtout construite en réaction à l’ambition totalisante du réalisme et de naturalisme, qui, recouvrant le réel de langage, l’étouffe. Pour résoudre la crise générale de la mimèsis, l’auteur entend rétablir un lien de motivation entre le langage et le réel. La deuxième partie s’attache à déterminer les aspects rhétoriques de l’écriture du simple, montrant que la simplicité s’inscrit également au cœur de la poétique de Jules Renard, déterminant des choix génériques et narratifs, et nécessitant un double mouvement de réduction et de concentration, qui n’est pas sans écueils. La simplicité n’est pas pour autant un thème de prédilection qui se développerait de manière linéaire chez l’auteur, elle oriente une dynamique, ouvrant un cheminement dialectique, difficile et peuplé d’obstacles. La dernière partie en montre la dimension morale, pratique et philosophique. La simplicité n’est pas pour Renard une donnée immédiate de la conscience, mais une valeur à construire et à défendre sur le terrain politique, qui s’enracine dans un terreau philosophique fondé sur la notion d’immédiateté. / Jules Renard’s ceaseless ambition is to try and be simple. Although his lack of imagination, which leads him to favour things that he saw and to draw on the sometimes narrow everyday life, reduces him to simplicity, he does not passively receive it but on the contrary ensures that blurring and reduction are key principles of his literary art. The first part of this thesis tackles with the writer’s theoretical and aesthetic questioning, understood in the literary landscape of the late fin de siècle. Even if Renard partly inherits the classic and realistic models, his simplicity is mostly built against realism’s and naturalism’s totalizing ambition, which suffocates the reality by covering it up with words. So as to solve the general crisis of the mimesis, the writer intends to build a bridge between language and reality. The second part of this work tries to single out the theoretical characteristics of the simple style. It shows that simplicity stands at the very center of Renard’s poetics, underlies choices related to the genre or the narration and implies both reduction and concentration, which is not easy to fulfill. Simplicity is not, on the other hand, a favourite topic with a linear development, but it triggers off a dynamic, dialectical and difficult process. The last part reveals its moral, practical and philosophical aspect. For simplicity is not for Renard an immediate matter of consciousness but a value which is to build and to defend politically. It is philosophically rooted in immediacy.

Availability of internet to a wide audiences has revolutionized how business is performed. Businesses now use e-commerce to trade products and services. The growth of e-commerce has been dramatically rapid among developed countries. Therefore, the adoption of e-commerce platforms is studied in these countries. Meanwhile less attentions has been given to developing countries. Developing countries can take advantage of lessons learned in the developed countries. One of the major success factors of e-commerce platforms in developed countries is improving the usability of e-commerce platform by considering user’s preferences. User preferences can be defined as feelings and attitudes of users for the interface and functional design of the ecommerce platform. This influences user’s decision and behavior. Considering the users preferences within an e-commerce platform enhances user’s satisfaction and increases user’s loyalty to the platform. To evaluate the user preferences a selection of usability factors are usually studied. Avicenna Research Institute (ARI) is currently considering the development of an e-commerce platform. For this ARI is investigating ways to consider users preferences in the design. This study aims to satisfy this goal. In this study previous research are analyzed, user’s preferences are identified, common used e-commerce platforms are investigated, and ARI’s perspective is included in the analysis. Using these information a set of recommendations on how to improve the usability of an e-commerce platform is given. For this task based approaches are used in form of participatory heuristic evaluation and observations. Interview is used to obtain ARI’s perspective on usability. The study has identified ten usability factors affecting the usability of the e-commerce platform based on user’s preferences. These include consistency, learnability, navigability, simplicity, readability, content relevance, supportability, interactivity, credibility, and telepresence. In addition a set of eighty evaluation criteria are presented to evaluate these factors. Using a qualitative approach, the study has analyzed all these factors in a multiple-case study. The analysis includes input from the users in form of observations, comments and questionnaire. This is combined with input from ARI in form of interviews. Finally the study concludes by providing a path for future research.

Dans cette thèse, nous étudions l’implémentation des contraintes de simplicité dans le nouveau modèle de mousses de spin d’Engle-Pereira-Rovelli-Livine, ainsi que les fonctions de corrélation à deux points de ce modèle. Nous définissons d’une manière simple l’espace de Hilbert limite de la théorie, puis montrons directement que toutes les contraintes s’annulent faiblement sur cet espace. Nous observons que la solution générale a cette contrainte (imposée faiblement) dépend d’un nombre quantique, en plus de ceux de la gravitation quantique a boucles. Nous généralisons également cette construction pour la version de Kaminski-Kisielowski-Lewandowski, ou la mousse n’est pas duale à une triangulation. Nous montrons que cette théorie peut aussi être obtenue comme une théorie BF satisfaisant la contrainte de simplicité, cette fois discrétisée sur un 2-complexe cellulaire oriente. Enfin, nous calculons la fonction de corrélation a deux points du modèle de mousses de spin Engle-Pereira-Rovelli-Livine avec la signature lorentzienne, et nous montrons que la fonction a deux points que nous obtenons correspond dans une certaine limite a celle obtenue a partir du calcul de Regge lorentzien. / In this thesis we study the implementation of simplicity constraints that defines the recent Engle-Pereira-Rovelli-Livine spinfoam model and two-point correlation functions of this model. We define in a simple way the boundary Hilbert space of the theory; then show directly that all constraints vanish on this space in a weak sense. We point out that the general solution to this constraint (imposed weakly) depends on a quantum number in addition to those of loop quantum gravity. We also generalize this construction to Kami´nski-Kisielowski-Lewandowski version where the foam is not dual to a triangulation. We show that this theory can still be obtained as a constrained BF theory satisfying the simplicity constraint, now discretized on a general oriented 2-cell complex. Finally, we calculate the twopoint correlation function of the Engle-Pereira-Rovelli-Livine spinfoam model in the Lorentzian signature, and show the two-point function we obtain exactly matches the one obtained from Lorentzian Regge calculus in some limit.

Chez Guillevic, le statut de la rhétorique est paradoxal. Toute l’œuvre est traversée par un impératif des choses et du réel qui s’accompagne d’un vœu de simplicité. Cette poésie, qui se voit rappelée à l’ordre du concret, se méfie d’une rhétorique qui viendrait éclipser la réalité des choses, ou accroître la distance entre ces deux pôles, que sont l’expérience du monde et sa mise en mots. Les poèmes, denses et resserrés sur eux-mêmes, se présentent alors manifestement comme un défi à la rhétorique. Pourtant, nous n’assistons pas à une éviction de la notion, mais plutôt à un ensemble de mutations, qui supposent une subrogation des valeurs la définissant. En effet, si Guillevic passe pour un poète qui se serait spontanément tourné vers le monde et vers les objets, ce rapport au réel, au départ, n’a rien d’euphorique. Il reste à construire car le monde se rétracte. Il faut retrouver une force dans le langage ; une force agissante. Se méfier d’une rhétorique éloquente et ornementale revient alors à inscrire dans le poème une tension qui fait du langage un support solide auquel se raccrocher ; les figures ne sont plus de l’ordre de la figuration mais de celui de la mise en rapport. On assiste donc à des processus de relittéralisation et de défiguration du langage, ce qui fait qu’il n’est plus question d’une rhétorique de surface, mais d’une rhétorique fondamentale, qui passe par un engagement de l’être dans le langage. Et comme il s’agit toujours de chercher à faire l’expérience du monde, plutôt que de s’obstiner à lui trouver un sens, la rhétorique est alors dissociée de ces notions de conceptualité, de représentation et de signification qu’elle a tendance à véhiculer. Enfin, chez Guillevic, se méfier de la rhétorique, c’est aussi remplacer la métaphore par l’ellipse et instaurer dans le poème un creux, ou un entre-deux, qui, sans pour autant annuler ce constat d’une inadéquation fondamentale entre le langage et la réalité, ne se présente pas moins comme le lieu où peut advenir une dimension neuve et originelle du sujet, du langage et du monde. / In the work of Guillevic, the status of rhetoric is paradoxical. All the work is characterised by an imperative of reality. The most important is simplicity. So, this poetry, which is called to reality, constantly distrusts rhetoric : indeed, rhetoric could overshadow the reality of the things and increase the distance between these two poles, that are the experience of the world, and its implementation in word. The poems, dense and tight on themselves, appear clearly as a challenge to rhetoric.However, in the work of Guillevic, the notion of rhetoric is not totally forgotten. On the contrary, we can note some mutations of the notion. The defining values are modified. Indeed, Guillevic is considered as a poet who spontaneously turned himself to the world and to the objects, but, first, this contact with reality is very difficult. This contact needs to be built or to be modified because, in the beginning, the world frightens. It is reluctant to welcome the poet. That is why Guillevic must find a strength in the language in order to build or to appease this relation between the subject and the world. And, paradoxically, distrust big rhetoric and its eloquence enables to do that, because this distrust puts a tension in the poem. First, this tension transforms the language of the poem and makes it as a solid to cling to. Then, the figures of speech no more belong to the order of representation but they belong to this necessity of a better relation between the subject, the language and the world. The poem tends to literality and to ‘disfiguration’. So, it is no more about a superficial rhetoric ; the rhetoric is now fundamental and joins the language and the being. The experience of the world is more important than the meaning, so that we can say that the notion of rhetoric is no longer connected to the concepts of conceptuality, representation and meaning. And we can also note that Guillevic replaces the metaphor by the ellipse : distrust rhetoric opens in the poem an empty place where these three elements that are the language, the poetic subject and the world can revive.
