Full textThis thesis investigates the uses and functions of colour in Florentine panel painting of the Trecento. As the first study on this topic, it moves beyond a mere analysis of hues, using a multidisciplinary approach that incorporates lexicography, material studies, and visual analysis. To determine the role of colour within Florentine society, the first section undertakes a comprehensive examination of colour vocabulary in 14th-century Italian languages, revealing both the significance of red within Florentine culture and the neutrality of colour terms regardless of context. The second section provides a synthesis of previous studies on the material history of colour and an overview of the materials and their application techniques. It highlights the inherent complexity of tempera techniques and the systematic use of pigments, while also allowing for some adaptability to artists' preferences. Finally, the third section examines the functions of colour within images, from both iconographic and pictorial perspectives. This study brings to light the systems underpinning painter colour choices, showing that, while certain individual preferences may be identified, the use of colour in panel paintings follows iconographic, rhetorical, and functional rationales reflecting the intellectual, religious, and artistic context of the period

Full textThis doctoral thesis suggests questionning how light, a natural and physical phenomenon has also become a concept in the field of painting. Light, artifical or natural, is not only the mere driving force behind vision for the majority of beings in this world, it is also at the origin of colors, which result from the action of light on the eye. By interacting directly with the material, light produces color. Therefore, to think philosophically the concept of light in pictorial art would thus means first to understand the inner ways of color, which have been gradually recognized as the true specificity of painting. Intrinsically connected within any perceptive experience, light and color involve a physiological process paradigm which evolved in the course of the centuries. Color reveals a visible world whose bright origin still cannot be grasped by our perception, and painters have worked to release the invisible origin of the visible: light, the essence of the visibility. The role of the perceiving subject is then profoundly transformed as it becomes regarded as the active agent of the optical experience. The visible world, thus far a privileged shape of knowledge, is reconsidered according to the subjective characteristics of the eye. By becoming an object of knowledge, vision became associated to the fields of philosophy and experimental sciences. Most precisely, since the concept of light meets in their works such rich aesthetic problems which resonate with the artistic paradigms that belong to the history of painting, it is throughout an analysis of Mark Rothko’s and Pierre Soulages’s work that the research work has been focused in a second part

Full textThis research attempts to determine how the implementation of systems and processes in artistic work carries with it an attitude. This attitude, which arises from the use of imported colour or ready-made colour, implies thinking of colour as a practice, modifying the artist's position and looking at painting as the creation of "objects over there" that have to fit among other everyday objects. Thus this research gives an account of displacements that, initiated by the use of industrial colour or that of common objects, create a back-and-forth movement between the viewer, the painting and the world, and make a new sharing of vision possible

Full textColour is omnipresent and exists at scale. As an anecdotal somponent of the landscape, its part in geographical description is barely significant. Whilst surveying the epistemological evolution of geographical science, it appears that colour may be a meaningful element of analysing more and more carefully the social and cultural composition. The study of colour in built-up landscape, applied to piemont region and its main city, turin, stresses the multitude of parameters which underline its use; its evolution in time and according to various scales can be measured through the analysis frame of the anthropological project. As the fram is related to the mesological diagram, colour acquires a new role in the analysis, since it belong likewise to the environment, the natural setting developed by man, the space or the geographical environment. Being part of these areas and their overlapping, as well as the progressive fragmentation of space by rapid changes imply the complexity of analysis. As a devices for analysis of geography, colour leads to the concept of territory; bestowed with meaning, it enables societies to locate themselves within a space whose boundaries are floating but acknowledged

Full textWatermarking consists in inserted information (signature or mark) inside a document. In the domain of Intellectual Property, the signature allows identifying the author of the document. In this work, we focus on image watermarking, and particularly on its colour dimension. Then, we have developed a watermarking technique, based on a manipulation of wavelet coefficients, where the mark is robust to compressions JPEG and JPEG2000, noise adding, median and low-band filtering and histogram equalization. After that, we have developed optimisation techniques. The main one combines texture segmentation and a retroactive method (exploiting colour metric), in order to fix local insertion strength of the mark, optimizing the watermarking for each treated image

Full textThis doctoral thesis introduces the extension of the LIP (Logarithmic Image Processing) model to color images. The CoLIP (Color Logarithmic Image Processing) model is defined, studied and applied to image processing in this manuscript. The Logarithmic Image Processing (LIP) approach is a mathematical framework developed for the representation and processing of images valued in a bounded intensity range. The LIP theory is physically and psychophysically well justified since it is consistent with several laws of human brightness perception and with the multiplicative image formation model. Following a study of color vision and color science, the CoLIP model is constructed according to the human color perception stages, while integrating the mathematical framework of the LIP.Initially, the CoLIP is constructed by following the photoreception, non-linear cone compression, and opponent processing human color perception steps. It is developed as a color space representing a color image by a set of three antagonists tones functions, that can be combined by means of specific CoLIP operations: addition, scalar multiplication, and subtraction, which provide to the CoLIP framework a vector space structure. Then, as the CoLIP color space is a luminance-chrominance uniform color space, relative and absolute perception attributes (hue, chroma, colorfulness, brightness, lightness, and saturation) can be defined. Thus, the CoLIP framework combines advantages of a mathematically well structured vector space, and advantages of a color appearance model. In a second step, physical, mathematical, physiological and psychophysical justifications are proposed including a comparison of MacAdam ellipses shapes in the CoLIP uniform model, and in other uniform models, based on ellipses area and eccentricity criterions. Finally, various applications using the CoLIP vector space structure are proposed, such as contrast enhancement, image enhancement and edge detection. Applications using the CoLIP color appearance model structure, defined on hue, brightness and saturation criterions are also proposed. A specific application dedicated to the quantification of viable cells from samples obtained after cytocentrifugation process and coloration is also presented

Full textLight emitting diodes (LEDs) are good candidates to become the main light sources of the future given their good efficiency and long life. However, a problem associated to the use of LEDs is the color shift observed at different temperatures, currents and lifetime. The purpose of this work was to implement a control algorithm that uses a color sensor as feedback. Two algorithms were developed to calibrate the detectors. The algorithms were implemented to control RGBA and RGBW LEDs. The first algorithm provides a good calibration for a restricted range of color near the calibration. The second algorithm gives good performances for the entire range of color available to the lamp, but it is less precise than the first algorithm.

Full textAlthough interest in the domestic sphere is a challenge for research as well as for design and for the industry, empirical data remain scarce. Within a praxeological and interactional perspective, this thesis contributes to filling this gap. It identifies specific resources of the everyday life organisation in two French homes. Through the analysis of interviews, and especially through the analysis of audio-video data, this thesis sheds light on the importance of the interactional work that members are deploying every day in their homes to order and make their activities accountable to each other. This work is based on multiple practices (such as verbalisation of actions, announcements, solicitations, directives, etc.) and resources that mark and set the time sequences of activities and open negotiation between adults and children. Besides the conversational time givers, body and artefactual material time givers are also massively mobilised. Thus, the coordination and organisation of activities is not a simple matter of time management, since they rely on a constant practical orientation anchored in specific material and care environments. From the perspective of technological design, the family members’ socialisation within a certain time and domestic normality is a central phenomenon. Sophistication or the multiplication of technical elements is not enough (and can represent a problem) with regard to the development of innovative systems for homes. Using notions of distributed temporality and interactional time givers seems to be an appropriate trial to study home and family activities

Full textThe first cartularies were written between the beginning of the 9th century and the first decades of the 10th century. Seven institutions are concerned: in Bavaria (Passau, Regensburg, Freising, Mondsee), in Fulda, Werden, Weissenburg and in the Chur-Rhetian. « Cartularization » means copying charters into quires. The copying process and its aims are the key points of this PhD thesis. This study is dedicated to the emergence of the first cartularies in the light of recent approaches regarding literacy. Comparing cartularies and other documents would be the core of our method in order to define them in a better way. We will first examine the origins of cartularies. Then, we will analyze their various functions (its identity, political context, the institutional context and its treatment). All these observations will lead to the discussion of the birth of cartularies in order to understand the copying issues and its difficulties

Full textThis thesis sets out a semi-fragile watermarking specially designed for color images. After a brief survey of the existing watermarking methods and a general presentation of the watermarking solutions, the watermarking method will be detailed. The latter is not only adaptable to all color spaces but allows the use of hybrid spaces as well. Taking into account the Human Visual System enables to minimize the image deterioration due to the embedded watermark. The use of the L*a*b* space to calculate the color distance makes it possible. Our schema is based on the modulation of the color representation of an image according to a pattern generated by a secret key. We can use 1, 2 or 3 dimensional patterns according to the selected insertion space. A second parameter enables to vary the watermark insertion force in order to reach a compromise between robustness and invisibility. This paper also proposes a steganography method. Our schema permits to insert a message in an image without adding new colors. Moreover, it is also possible to insert a message by adding colors in the image in a controlled way. The schema resistance and the visual deterioration generated on the image by the watermarking are analyzed thanks to numerous tests on a determined set of images. In order to illustrate the possible uses of these methods, we will finally present two applications using both the watermarking system and the steganography schema

Full textMany environmental advantages of wood in buildings have been thoroughly documented; however this material’s effects on occupants are not well known and fully comprehended. Previous studies have demonstrated that factors unrelated to the indoor environment quality can affect comfort, but the influence of materiality is seldom considered. This research focused on studying occupant comfort in a multifunctional room characterised by extensive wood surfaces in comparison with a similar room with more conventional surfaces at Laval University, Quebec, Canada. The objectives of this research focus on better understanding how occupants perceive wood in built environments, determining the thermal, visual, acoustical and olfactory similarities and differences between two rooms using on-site surveys and exploring whether the indoor use of wood influences occupant comfort. A comparative study within a post-occupancy evaluation framework analysed the subjective perception of building occupants in relation to physical comfort factors. A total of 36 occupants completed a questionnaire elaborated to compare comfort satisfaction between two rooms with different interior finishes. Analysis of instrumental measurements and images of each room’s indoor environment determined the similarities and differences between the rooms. Quantitative and qualitative analyses reveal that both rooms share similar thermal and acoustic comfort parameters, but present contrasting visual characteristics. The colour, knots and grain of the wood contributed to visually warm experiences resulting in a yellowish room whereas a mix and match of artificial finishes generated a colder, bluish ambiance in the other room. Results from the questionnaire indicate that occupants were generally more satisfied in the room with extensive wood surfaces in terms of lighting, noise and temperature despite objectively similar environmental conditions in both rooms. The conclusion reached is that architects should consider the indoor use of wood for its unique visual ambiances that enhance comfort levels.

The analysis of self-medication is a way to reintroduce the body by showing the links with the others part of the practice (representations, objects and competences) and by highlighting its role in shaping the practice : (1) the relationship to the body contributes to consumers’ experimentations, (2) practices embodiment leads to the reproduction of the practice and (3) it can contribute to the preservation of a bodily capital. Beyond these bodily considerations, we distinguish several practices of self-medication and different kinds of hybridization of practices

Full textWith the constant increase of international felony and criminality, more and more offences take place partially or totally out of France. In order to submit theses offences with a foreign element to the French criminal law, the national lawmaker and criminal courts are trying to repatriate these breaches within the French territory by trying to establish a link between France and the offence incorporating the foreign element. Since the National boundaries cannot be modified therefore the offence is legally modified. Consequently, the rules regarding the accomplishment of the offence will be modified in order to establish its location. The present Thesis leads to enhance an artificial progression which consists in retaining a connection for the offence, either pertaining to the material element of the offence but which cannot be taken into account or, either not pertaining to the material element of the offence which should not be taken into account

Full textThe memory creates a predisposition to move towards the evanescent moments of an intense memory because it declares itself as a certain deviation related to time and space, referring to where we're located. After analyzing the powers of remembrance in terms of dealing with artistic practices, we proposed to demonstrate that the work of art correlated with perception teaches us to fully grasp a potential materiality that makes possible a new analysis of our sensitivities. Due to works of art being based on a tangible reality, it is often confused with the formal process of materials that can support them . In particular, thinking about the materiality, not by the reflection of the artist's work, but by our feeling, changes completely our apprehensions. By way of an unobtrusive indication, the intensive sensation of the body leads us to recognise all those things which have contributed to transmitting the emotions felt and to enriching our memory. The artist operates a presentification of his/her emotional state and explores the connections and the disjunctions between the senses, in order to find herself/himself in a rhythm of the duration, which only exists if she/he participates at the same time. we have probed into a profile of the materiality of memory, with a view considering the tangible possibility of an emotional state within the framework of our different experiences, as a force for artistic creation. We attempted to recognise the specificity of this study and paid particular attention to the « process of creation », because our approach starts with practical and theoretical conditions, which may be combined with issues of the memory in the field of art

Full textOur research consists of a longitudinal study in which one group of pupils in ordinary classroomsituations has been followed from the top level of French pre-elementary school (5- to 6 year-oldpupils) to the second level of French primary school (7- to 8 year-old pupils). For these three schoolgrades, one of the main objectives in the curriculum is learning to read.We consider that pupils build their new reading skills, i.e. the skills characterizing their potentialdevelopment, by relying on skills characterizing their actual development (Vygotski, 1934/1997).When learning to read, pupils yet have at their disposal semiotic abilities related to knowledge bothof material objects and their uses, and of basic gestures and their meaning (Moro & Rodríguez,2005), all of this we sum up under the term of materiality. Consequently, in our research, we makethe hypothesis that the children’s basic abilities related to materiality constitute a resource inteaching-learning situations.We have chosen to carry out a case study. The data collected consist of videos of class sequencescarried out four times a year for three years. These twelve videos are supplemented by two semistructuredinterviews with the teacher, one “self-confronting” interview in which the teacher isbrought to discuss her actions and by the analysis of the ministry’s school curricula. Our analysis isboth macrogenetic and microgenetic. For each teaching sequence, on the level of macrogeneticanalysis, we have made up the synopsis from which we have selected significant episodes in terms ofmateriality. The significant episodes are composed of remarkable events the microgenetic analysis ofwhich requires the use of tools such as materiality boards and photograms.Our study shows that materiality enables pupils to develop reading skills and that the forms thatmateriality takes on change according to the pupils’ acquisition progress and the aspects of reading(code and comprehension) still to be learned

Full textIndustrial companies receive huge volumes of documents everyday. Automation, traceability, feeding information systems, reducing costs and processing times, dematerialization has a clear economic impact. In order to respect the industrial constraints, the traditional digitization process simplifies the images by performing a background/foreground separation. However, this binarization can lead to some segmentation and recognition errors. With the improvements of technology, the community of document analysis has shown a growing interest in the integration of color information in the process to enhance its performance. In order to work within the scope provided by our industrial partner in the digitization flow, an unsupervised segmentation approach was chosen. Our goal is to be able to cope with document images, even when they are encountered for the first time, regardless their content, their structure, and their color properties. To this end, the first issue of this project was to identify a reasonable number of main colors which are observable on an image. Then, we aim to group pixels having both close color properties and a logical or semantic unit into consistent color layers. Thus, provided as a set of binary images, these layers may be reinjected into the digitization chain as an alternative to the conventional binarization. Moreover, they also provide extra-information about colors which could be exploited for segmentation purpose, elements spotting, or as a descriptor. Therefore, we have proposed a spatio-colorimetric approach which gives a set of local regions, known as superpixels, which are perceptually meaningful. Their size is adapted to the content of the document images. These regions are then merged into global color layers by means of a multiresolution analysis

Full textSynesthesia is a fascinating phenomenon that offers the opportunity to study the neural bases of subjective experiences in healthy subjects. Grapheme-color synesthetes (1 to 5 % of the population – who do not know it most of the time) arbitrarily and systematically associate a specific color to letters or digits. This PhD thesis work focuses on this type of synesthesia and explores whether common neural networks are involved both in ‘real' color perception and synesthetic color experience. In a previous study from the host team using functional Magnetic Resonance Imaging (MRI), no implication of ‘color areas' where found (Hupé et al., 2012). A standard (univariate) statistical analysis of the data processing was used.This PhD thesis aims at determining if synesthetic colors involve real color neural networks with the use of a multivariate statistical technique (Multivoxel Pattern Analysis – MVPA). Unlike univariate analysis it uses sets of voxels (the pixels in 3D forming the images) and take into account their patterns of activation linked to the encoding of specific information in the brain. This encoding is performed at the neuronal level and fMRI indirectly and non-invasively quantifies it through hemodynamic variations induced by the neuronal activity. MVPA is a particularly adapted approach to measure fine grained and distributed information encoding. The goal of the thesis is to explore its efficiency for the study of grapheme-color synesthesia for which standard analyses failed. In practice, it requires the use of specific protocols, mastering numerous parameters influencing the results and the joint use of univariate analysis. In the first step of this thesis, we evaluated different methodological aspects to optimize the processing chain in order to obtain robust and reliable results.Then, we compared the neural processing of real colors and synesthetic colors in 2 groups of synesthetes (n=20) and non synesthetes (n=20). We found that synesthetic colors processing does not share common neural networks with real color processing. This suggests that the neural bases of synesthetic colors are not localized in the retinotopic visual areas or in the visual expertise areas (the ‘ventral pathway' areas). This may also suggest that, although those areas are involved, different neural networks are implicated in real color and synesthetic color perception. These results raise the question of the limits of the interpretation of the signal measured by fMRI, indirectly linked to the neuronal activity. The identification of the neural networks involved in the subjective experience of synesthetic colors remains an open issue

Full textThe use of colour in Lawrence Durrell's novels and travel books highlights different aesthetic choices from earlier to later works, showing the ambivalence of Durrell's artistic positions. Colour appears to partake of a baroque anti-classical inspiration both because of over-inscription and because of optical illusion produced by reflections and mirages. The result very often suggests a blurred picture, which it is impossible either to "read" or even "see". However, the tendency to use names of things as colour-words may turn the blurred picture into a seemingly tactile representation. Colour within the text thus provides a way of grasping what, by definition, eludes language, i. E. The visual, by recreating a three-dimensional image, an image that one might "see", "read", and "touch"

Full textThe early novels of John Dos Passos are part of the modernist literary movement. They are characterized by an original organization of the words on the page. The text is no longer a monolithic block, but is divided into sections and its separations are highlighted by a vast paratext. It also contains a variety of collages presented in various styles and in different fonts. These observations are the starting point of this research, which focuses on the materiality of the text in the early novels of John Dos Passos, Manhattan Transfer and the trilogy USA, published between 1925 and 1938. These novels question the gaze of the reader on the text, showing what is placed in front of and around the eye of the observer. The reader becomes aware of what influences his vision. The novel displays its internal structure and various thresholds, allowing the reader to continue or to stop reading, to go backwards and to create connections between the different sections of the text. The novel displays how it has been constructed, highlighting that it is the product of the rearrangement of previous texts. This visible internal structure is also built out of gaps and empty spaces. It reflects the tension between the ambition to be exhaustive, to contain everything and to acknowledge the difficulty to tell a story. The interplay with the blank space on the page, the use of punctuation and phonetic indicators reinforce the written aspect of the text, while at the same time making the words stand off the page and resistant to closure

Full textThis thesis aims to show the epistemological principles of Gottfried Wilhelm Leibniz's schorlarly practices, that he have implemented as a "professional" historian. The work contains three parts. The first one discusses several ways to define the concept of history in Leibniz' thoughts: in the first chapter I justify the use of a practical and scholarly approach to define the leibnizian theory of historical knowledge, then in a second I explore how the historical knowledge is ordered and constituted in historical books; finally in a third one I distinguish between natural history and civil history and try to show what this one is. As God is the only "historian" capable of knowing the true causes of the "factual truths (vérités de fait)", the only thing a historian in his time can do, according to Leibniz, is to find and gather the marks of the past, to order them and show them as if they belong to a theatral scene through which the spectators can perceive the past events and things. As God is the only "historian" capable of knowing the true causes of the "factual truths (vérités de fait)", the only thing a historian in his time can do, according to Leibniz, is to find and gather the marks of the past, to order them and show them as if they belong to a theatral scene through which the spectators can perceive the past events and things. The second part deals with the historical works themselves and what makes them being good enough to belong to the disciplinary field of history. In a first chapter, I discuss the methodological principles of publishing history, and, in a second one, I cover how the paratext (preface, footnotes) of his more ambitious collection of historical sources, namely the Scriptores Rerum Brunsvicensium (1707-1711), justifies its content by staging a form of "critical art". What we see is that the sources are treated differently when edited by on the one hand Leibniz or Eckhart, who are historians, and on the other, by scribes, who have philological training firstly. Historians focus on the history of manuscripts transmission, testimonies, and events, with an approach both educational and erudite; whilst philologists focus on the "materiality" of texts and the history of language. Historical knowledge therefore is a collective knowledge. Finally in the third part I look at the birth of the Leibnizian "ars critica" involved in discriminating in artefacts and texts what is and isn't historical sources. Artefacts in that perspective are matter of new kinds of inquiry, and the question of their status is discussed, that is if they are "auxiliaries" of history or historical themselves

Full textTo summarize, this dissertation adopts a vital materialist perspective (in terms of its ontological orientation), a phenomenological perspective (in terms of its epistemology), and an interpretive perspective (in terms of its methodology) to explore several gaps as they transpire in contemporary consumption theory. The first essay explores the lived experience of consumers with materials, or what things are made of, thus shifting the scale from the usual object-centered theorization to a more micro dimension. The second essay proposes a materials-driven research agenda, which merges the principles of vital materialism with the current sustainability crises.The third essay merges vital materialism with conventional material culture approach to understand an emerging class of commodities that defy market rules and carve out a novel niche of meaning for materiality in consumption (i.e., using goods to preserve and increase one’s financial capital)
Maurial, Sandrine. "Une alchimie lumineuse : pigment et pixel comme atomes de la couleur." Bordeaux 3, 2005. http://www.theses.fr/2005BOR30044.
Full textThis artistic and philosophical reflection approaches the color phenomenon through a transverse way, by weaving bonds between the pigments of the " traditional " painter and the pixels of the " digital " artist. This relation underlines the interaction between the matter and light, which are both constitutive components of color. Thus, color can be explored from its smallest components while releasing its mysterious dimension, as well as its social and cultural resonance. As regards art history, the treatment of color by artists depends on scientific research and technological rise, while reflecting the current state of the society in which the artist evolves. Artists have tried out color under its various states, from the color/matter to the color/light, insisting on its real texture as well as on the virtual one. Nowadays, digital color is being propagated from the computer science to the artistic field, preserving its material memory

Full textColour is omnipresent in our daily lives, but its representation in today’s marketing shows a double paradox: on the one hand, the use of advertising rhetoric, invoking characteristics of color – the same being manifestly denied by the manufacturing industry, and on the other hand, the multiplication of the image of color chart – but under printing-conditions that are opposed to the functions of exemplification it is supposed to fulfill. Using tools from poietic, this thesis intends to demonstrate what kind of changes manufacturers, industry and commerce has gone through in terms of construction of theidea of colour since the mid-nineteenth Century by questioning its various sampling modes, in particular how the color chart was introduced by manufacturers. Sampling of colour is here considered as an interface of maximum expression betweencolour producers and traders and those for whom it is intended: it originates from specific creative conducts - which it also generates. The purpose of this work is to measure the evolution of each type of provided - and obviously communicated - information through the color chart. The research is anchored to a body of documentation, upon which an analytical grid isapplied, first of all in order to define the five fields of information the colour sampling has allowed for. It also enables one to explore their quantitative and qualitative characteristics. Thus it has been possible to develop operational concepts in order to define precisely two distinct creative lines: one generating the color chart and the other generating the sample collection. The chronological amplitude of this research and the prejudice to let the field maintain its ability to display all its treasures, has imposed its own limitations to this research. It has defined the framework and the main landmarks of a - until now - poorly explored subject and developed the conceptual tools capable of being re-used. An evaluation has been performed on the adequacy of the methodology, the tools and on implemented concepts. The results are encouraging as they show that the undertaken research has successfully identified the issues the color chart, the rich entity of where it comes from and what it leads to can contribute to deciphering contemporary society. The purpose is to extend this first step by carrying out new investigations on the sampling of color

Full textRecent developments in digital fabrication practices across the fields of art, architecture and design have inspired the notion of a “new materiality” — a rethinking of our relationship to the physical world in light of the ever-increasing convergence between robotics, computation and materials science. Yet, the very use of computer-controlled machinery remains, more often than not, envisioned in terms of a passive understanding of matter. This thesis aims at offering an updated vision of the relationship between materiality and design, by developing new production schemes allowing for an expression of material agency. Criticizing the traditional idea of a prescriptive, deterministic link between design and fabrication, the proposed argument reframes authority as a shared resource, spread through a network of productive and autonomous agents. The thesis' main outcomes consist in a set of practical methodologies as well as an encompassing conceptual framework, which may both be reinvested by other practitioners. Informed by and grounded in practice, the research builds on five experiments, adopting a prospective approach towards programming and digital fabrication. Drawing on authors like Gilbert Simondon and Andrew Pickering, the accompanying conceptualization allows for a reflexive discussion of the thesis' practical developments, while situating them in respect to such historical precedents as non standard production and cybernetics
Laguian, Claire. "Faire et défaire le Monde : tensions et matérialité dans l’œuvre poétique d'Andrés Sánchez Robayna." Thesis, Paris Est, 2019. http://www.theses.fr/2019PESC2064.
Full textThis dissertation offers a reading of the various framing structures in the poetic works, essays and Diarios published between 1970 and 2010 by Andrés Sánchez Robayna, a Spanish poet and academic born in the Canary Islands in 1952. The poet’s dialectical and metaphysical approach reveals a linguistic and ontological quest stemming from the crisis of modernity. The tensions to be found in the poems are inspired by a contemplation of landscapes, which are often insular, and lead to the emergence of interstices within which language experiences an epiphany in progress. This permanent search for a reconciliation between doing and undoing examines the poïetics of the Robaynian cosmos, thanks to a metapoetic discourse on the advent of artistic works in the texts. Besides, the disintegration processes which break up, cut into, cancel and calcine the verbal matter also allow for some opening and ultimate unification, in a sensitive and spiritual perspective inherited from the mystics. Tools from various textual approaches (metrics, rhythmics, stylistics, but also linguistics) are used here to analyse and interpret the poetic language and expose the internal structures of the Robaynian system. As Andrés Sánchez Robayna’s poetic practice owes much to tradition, our reading is also based on the dialogue between poetry and the other arts (music, painting, sculpture and architecture) and on philosophical and sacred perspectives, from the pre-Socratic thought to the apophatic mystics, from the Neoplatonists to alchemy, and from ontology to phenomenology. The experience of the tangible world by the body immersed in contemplation is intertwined with the one, more intellectual and geometric, of cosmic apprehension, yet both aim at some ephemeral grip on the materiality of the World. The symbolical strength of geology and the mineral, added to that of insularity, prompts a new sacralisation of language, thanks to which the latter retrieves its long-lost matter and rekindles the ontological quest

Full textThis thesis is divided into two main parts: 1. the proposal of a concrete analysis methodology in discourse based on the dialectical-critical method. This methodology is focused on the possibilities of apprehending the object to which the discourse refers, in order to provide subsidies to the researcher in the identification of ideologies and power relations present in the organizational discourses, as well as to verify if there are discourses that are revealed as hegemonic in contrast of other discourses that are marginalized; 2. The application of this methodology in the case study of the rupture of the tailings dam of Fundão, owned by Samarco and its shareholders, Vale S.A. and BHP Billinton. The main objective is how to appropriate the object through the discourse or how to consider the discourse as a form of access to the object. At first, the epistemological approach is discussed, the perspective of language assumed throughout the work , the potentialities of work with the dialogical perspective of discourse analysis, as well as the theories of argumentation. Then, the relations between discourse and ideologies are examined, trying to define a way to interpret this theme in discourses. Based on these assumptions, it is discussed the two fundamental themes necessaries for the elaboration of a dialectical-critical methodologies applied to discourse analysis. The first refers to the approach of discourse and action as two distinct dimensions, which mediate the relationship between thought and concrete reality and are part of a process that leads to the appropriation of the real by individual consciousness. Based on the foundations of concrete criticism and premises of the philosopher Karel Kosik, strategies are defined to approach the discourses that can point to the object to which they refer. In this approach, the contradictions between discourse and action are analyzed, starting from the situational conditions in which the discourse is inserted, considering mainly the context (historical, geographic, political, economic), the concrete referents of discourse content, and the ideologies that circulate around the case. This methodology is then used to analyze the case of Samarco, a company involved in the rupture of the Fundão dam in Bento Rodrigues. The approach to case analysis was based on the thesis and antithesis in the kosikean conception, which is based on a historical materialist conception. The thesis on which the analyzes are based is that the Government represents primarily the interests of the population affected, with all those involved in the Mariana case being equal before the law. The dialectical contradiction of the thesis consists in the fact that the economic interests of the organizations involved largely define government policies related to mining. From this contradiction, the discourses that circulate around the rupture of the Fundão dam are analyzed with a specific methodology
