Objets théoriques : une perspective modale sur leur mode d'existence et sur leur rôle dans l'argumentation / Theoretical objects : a modal perspective on their mode of existence and their role in argumentationGallais, Matthieu 05 October 2018 (has links)
S’inscrivant dans la philosophie de la connaissance et des sciences, notre étude traite des objets théoriques, selon une perspective modale inédite. Les connaissances théoriques ont pour finalité de porter sur des vérités factuelles,et traditionnellement, on considère par conséquent que ces connaissances peuvent être formulées dans un cadre extensionnel : en termes d’adéquation ou tout au moins de relations avec des objets de notre monde actuel. Mais nous appuyant sur les avancées récentes de la philosophie de la logique modale,nous soutenons que l’entreprise scientifique conçoit des modèles théoriques qui portent sur tout un ensemble de situations, car ils postulent des objets qui sont à considérer dans une perspective modale : les objets théoriques sont intrinsèquement modaux, existant ou pouvant être reconnus dans une pluralité de situations actuelles ou possibles. Cet aspect modal des modèles scientifiques nécessite donc d’examiner l’identification des objets théoriques à travers diverses circonstances alternatives éventuelles. En effet, la question de l’application d’un modèle scientifique, liée au débat fondamental entre réalisme et instrumentalisme, prend selon nous racine dans le problème modal de la reconnaissance d’un objet théorique idéal en un objet actuel ou possible. La notion de modalité nous sera donc utile dans l’analyse fondamentale de l’argumentation scientifique. / In the field of the philosophy of knowledge and science, my study deals with theoretical objects in a new modal perspective. Theoretical knowledge is intended to cover factual truths and therefore one traditionally considers that this knowledge can be formulated in an extensional framework: in terms of adequacy, or, at least, of relationships with objects of our actual world. But basing my work on recent advances in the philosophy of modal logic, I will argue that scientific enterprise develops theoretical models about a variety of situations because they postulate objects that have to be considered in a modal perspective: theoretical objects are intrinsically modal, existing or recognizable in a plurality of actual or possible situations. Therefore, this modal aspect of scientific models requires that the identification of theoretical objects across various possible alternative circumstances should be examined. Indeed, the issue of the application of a scientific model, linked to the fundamental debate between realism and instrumentalism, lies with recognizing an ideal theoretical object in an actual or possible object. The concept of modality will also be useful in the fundamental analysis of scientific argumentation.

Sarah Sze's "Triple Point": Modeling a Phenomenological Experience of Contemporary LifePreuss, Amanda J. 16 April 2015 (has links)
In 2013, the 55th Venice Biennale, the world's oldest bi-annual international contemporary art exhibition, opened under the title The Encyclopedic Palace, organized by Italian curator Massimiliano Gioni. The international exhibition section is always flanked by an amalgamation of distinct national spaces, a dual exhibition model that has been the hallmark of the Biennale since 1998. In 2013, the United States pavilion was devoted to American artist Sarah Sze's work Triple Point and her signature arrangement of everyday objects and materials, such as Q-tips, water bottles, painter's tape, and desk lamps. The title of Sze's multi-room installation, culled from earlier works as well as created from new materials, refers to the thermodynamic equilibrium of any given substance--specifically, a "triple point" is the temperature and pressure at which a substance is solid, liquid and gas at the same time. The quasi-scientific installations provide constantly shifting viewpoints as the viewer circumnavigates the interconnected spaces of the U.S. pavilion, moving amid, around, and through the work, but also focusing on different individual objects before pulling back to catch glimpses of the work as a whole.
In this thesis, I apply a phenomenological analysis to Triple Point in order to make sense of its scientific references in conjunction with its complex form. I view Triple Point as a culmination of the ideas that Sze has sustained and explored over the course of her career--such as the investigation of everyday objects in relation to site, space, and viewer--that situates the viewer in an experience caught between empirical order and individual perception. To examine Triple Point using the idea of "embodied perception," I formally analyze the work in relation to its scientific meanings as suggested by its titles of individual works--Gleaner, Planetarium, Eclipse, Scale, Orrery, Pendulum, Observatory, and Compass. I then trace the discourse surrounding phenomenology and the rise of installation art through the writings of art historians Michael Fried, Rosalind Krauss, and Claire Bishop, before finally situating French philosopher Maurice Merleau-Ponty's phenomenology as an apt theory for analyzing this work. In embracing both the scientific objectivity implied by Sze's installations without sacrificing the import of physical perception, I contend that Triple Point invites the viewer to look at--but also beyond--the array of familiar objects, emphasizing a shifting sense of the work that is never exhaustively fixed. Thus, Triple Point does not expose the classic dichotomies between art and science, natural and manufactured, image and object, but instead opens up the moment of their confluence--the paradoxical achievement of an embodied perception as described by Merleau-Ponty. Understood phenomenologically, Triple Point invites viewers to get caught-up in the dynamic experience of "between-ness" invoked by the installation's title and to engage with their everyday experiences of contemporary life in a new way.

Tvorové vědy. Živé modely a budování vědeckých komunit / Creatures of Science, Living Models and the Construction of Scientific CommunitiesStella, Marco January 2014 (has links)
Creatures of Science. Living Models and the Construction of Scientific Communities. Marco Stella The present thesis, which is to be understood as a contribution both to history and anthropology of science, deals with the relationship of the construction and emergence of scientific communities and the use of models in science, or construction of new forms of knowledge. We deal primary with the history of life sciences, especially behavioral sciences, which formed in the beginning of the 20th century as a relatively independent a scientific field and a rather heterogeneous platform for a common research of life utterances and cognition of man and other animals. The thesis focuses mainly on living models, often used biological and psychological research. Using Latour's concepts of modernity and hybridity, the thesis points at the hybridizing effect of behavioral sciences (the model always shapes and creates the modelled) and also at their ways of human and animal images. The second often serve as a basis for constructing the second. I also discuss some the ways how implicit model properties, which influence the (seemingly) isolated sphere of science, affect the chances of a community for becoming a discipline. On three examples from the history of life sciences, i.e. the unsuccessful institutionalization of...

Botswana student teachers' views on the nature of science and scientific method: a critical reflectionKadiyala, Aparna 30 June 2005 (has links)
The assumption of the present study is that teachers should possess an adequate understanding of the nature of science and scientific method and hence this aspect was investigated. The empirical research carried out with Secondary School teacher trainees at Botswana colleges of education showed the following:
Subjects possess an adequate understanding of some aspects of the nature of science and several aspects of the scientific method. They however do not have an adequate understanding on certain aspects of the nature of science. An association was found between the nature of science, type of educational institution attended, years of study and majoring in science. A positive association was found between scientific method and years spent studying. The present study recommended the inclusion of history, philosophy and sociology of science in the curriculum of teacher education. / Educational Studies / M. Ed.

Eksegeties-metodologiese vooronderstellings van die ondersoek na die ekonomie in die leefwêreld van Matteus: toegepas op land, grondbesit en die jubilee (Afrikaans)Volschenk, G.J. (Gert Jacobus) 05 October 2001 (has links)
In Chapter 1 different phases of the application of exegetical methods with regard to texts in the New Testament were identified. Each phase provided a different perspective in response to questions about the contextuality of the New Testament. From the overview it became clear that the investigation of the historical background had received some attention, but it had not been as effectively utilized in the hermeneutical process as it could be, and had not been taken seriously enough. In Chapter 2, the place and function of the historical context or background of the New Testament in historical criticism, literary criticism and social scientific methods of exegesis were evaluated. Historical criticism often focuses on the different parts (forms) of the text, but does not consider the text as a whole to the degree required. Literary criticism focuses on the text as a whole. The Gospels are regarded as narrative texts. Narratology foregrounds the spatial aspects or topology of the Gospels. Socio-historical research on the world of the text, contributes to the study of the background of the New Testament. To enhance the progress already made, historical criticism and literary criticism can be supplemented by applying selected social scientific models. The use of such models makes it possible for socio-historical data to be systematized in a holistic interpretive framework. The use of social scientific models can bridge the historical distance between the text and its readers to avoid fallacies based on anachronism and ethnocentrism. A social scientific approach provides a holistic frame of reference for the interpretation of Biblical texts. However the approach may not pay enough attention to the topological or spacial aspects of the Gospel of Matthew. The model of advanced agrarian society and the pre-industrial city have not yet been applied effectively to the Gospel of Matthew. The current study fills this gap. In the study the model in terms of which an advanced agrarian society can be descibed, is used as a broad frame of reference within which the place and function of the Biblical jubilee can be studied. This diachronic overview of the research on the Biblical jubilee (Chapter 3) shows that no such study has as yet been undertaken with regard to the Biblical jubilee. Ancient economy developed from a simplistic agrarian society to an advanced agrarian society. The Roman Empire was the result of a long evolutionary process. Land was the primary economic resource in a self-sufficient society. The aim of the current research was to show that the socio-economic background of the first century forms the context within which the land and jubilee can be understood. The socio-economic background can be interpreted within a holistic perspective of first-century Mediterranean society. The social scientific model of advanced agrarian society includes four factors (family institutions, pre-industrial city, land tenancy and social stratification) that all influenced the land and economy of the first-century Mediterranean world. In Chapter 6, homomorphic models were used to simplify important and representative aspects of complex social structures, behaviour and relations. These models were used for the study of the political, economic and social systems of an empire or government. The current study used the social scientific model of advanced agrarian society as frame of reference for the interpretation of the place and function of the Biblical jubilee in the Gospel of Matthew. / Dissertation (DD(New Testament Studies))--University of Pretoria, 2001. / New Testament Studies / unrestricted

Modely a modelování v biomedicíně / Models and Modeling in the Biomedical SciencesZach, Martin January 2021 (has links)
Many scientific disciplines rely on the construction and use of models: biomedical sciences are no exception. This PhD thesis addresses several aspects of the practice of scientific modeling. First, I discuss the nature of modeling as such, proposing a novel, complementary account of scientific modeling which I term the experimentation-driven modeling account and which drives the construction of mechanistic models in many fields of biological and biomedical research, such as cancer immunology. Second, I scrutinize an objection to the mechanistic account of explanation according to which the account fails to accommodate the common practice of idealizing difference-making factors. I argue that this objection ultimately fails because it is riddled with a number of conceptual inconsistencies. Third, I analyze the roles of similarity judgments in some fields of cancer research which employ a variety of mouse models to learn about the disease mechanisms, arguing that by appreciating the epistemic complexities it is possible to shed new light on more general philosophical debates regarding scientific representation. Fourth, mechanisms can also be studied using more theoretical apparatus in the form of simulations. I investigate an example of an agent-based model used to model the outbreak of SARS-CoV-2...

The Darwinian revolution as a knowledge reorganizationZacharias, Sebastian 24 February 2015 (has links)
Die Dissertation leistet drei Beiträge zur Forschung: (1) Sie entwickelt ein neuartiges vierstufiges Modell wissenschaftlicher Theorien. Dieses Modell kombiniert logisch-empiristische Ansätze (Carnap, Popper, Frege) mit Konzepten von Metaphern & Narrativen (Wittgenstein, Burke, Morgan), erlaubt so deutlich präzisiere Beschreibungen wissenschaftlicher Theorien bereit und löst/mildert Widersprüche in logisch-empiristischen Modellen. (Realismus vs. Empirismus, analytische vs. synthetische Aussagen, Unterdeterminiertheit/ Holismus, wissenschaftliche Erklärungen, Demarkation) (2) Mit diesem Modell gelingt ein Reihenvergleich sechs biologischer Theorien von Lamarck (1809), über Cuvier (1811), Geoffroy St. Hilaire (1835), Chambers (1844-60), Owen (1848-68), Wallace (1855/8) zu Darwin (1859-1872). Dieser Vergleich offenbart eine interessante Asymmetrie: Vergleicht man Darwin mit je einem Vorgänger, so bestehen zahlreiche wichtige Unterschiede. Vergleicht man ihn mit fünf Vorgängern, verschwinden diese fast völlig: Darwins originärer Beitrag zur Revolution in der Biologie des 19.Jh ist klein und seine Antwort nur eine aus einer kontinuierlichen Serie auf die empirischen Herausforderungen durch Paläontologie & Biogeographie seit Ende des 18. Jh. (3) Eine gestufte Rezeptionsanalyse zeigt, warum wir dennoch von einer Darwinschen Revolution sprechen. Zuerst zeigt eine quantitative Analyse der fast 2.000 biologischen Artikel in Britannien zwischen 1858 und 1876, dass Darwinsche Konzepte zwar wichtige Neuerungen brachten, jedoch nicht singulär herausragen. Verlässt man die Biologie und schaut sich die Rezeption bei anderen Wissenschaftlern und gebildeten Laien an, wechselt das Bild: Je weiter man aus der Biologie heraustritt, desto weniger Ebenen biologischen Wissens kennen die Rezipienten und desto sichtbarer wird Darwins Beitrag. Schließlich findet sich sein Beitrag in den abstraktesten Ebenen des biologischen Wissens: in Narrativ und Weltbild – den Ebenen die Laien rezipieren. / The dissertation makes three contributions to research: (1) It develops a novel 4-level-model of scientific theories which combines logical-empirical ideas (Carnap, Popper, Frege) with concepts of metaphors & narratives (Wittgenstein, Burke, Morgan), providing a new powerful toolbox for the analysis & comparison of scientific theories and overcoming/softening contradictions in logical-empirical models. (realism vs. empiricism, analytic vs. synthetic statements, holism, theory-laden observations, scientific explanations, demarcation) (2) Based on this model, the dissertation compares six biological theories from Lamarck (1809), via Cuvier (1811), Geoffroy St. Hilaire (1835), Chambers (1844-60), Owen (1848-68), Wallace (1855/8) to Darwin (1859-1872) and reveals an interesting asymmetry: Compared to any one of his predecessors, Darwins theory appears very original, however, compared to all five predecessor theories, many of these differences disappear and it remains but a small original contribution by Darwin. Thus, Darwin’s is but one in a continuous series of responses to the challenges posed to biology by paleontology and biogeography since the end of the 18th century. (3) A 3-level reception analysis, finally, demonstrates why we speak of a Darwinian revolution nevertheless. (i) A quantitative analysis of nearly 2.000 biological articles reveals that Darwinian concepts where indeed an important theoretical innovation – but definitely not the most important of the time. (ii) When leaving the circle of biology and moving to scientists from other disciplines or educated laymen, the landscape changes. The further outside the biological community, the shallower the audience’s knowledge – and the more visible Darwin’s original contribution. After all, most of Darwin’s contribution can be found in the narrative and worldview of 19th century biology: the only level of knowledge which laymen receive.
