Social scientists increasingly use social media data to illuminate long-standing substantive questions in social science research. However, a key challenge of analyzing such data is their lower level of individual detail compared to highly detailed survey data. This limits the scope of substantive questions that can be addressed with these data. In this study, we provide a method to upgrade individual detail in terms of ethnicity in data gathered from social media via the use of register data. Our research aim (...) is twofold: first, we predict the most likely value of ethnicity, given one's first name, and second, we show how one can test hypotheses with the predicted values for ethnicity as an independent variable while simultaneously accounting for the uncertainty in these predictions. We apply our method to social network data collected from Facebook. We illustrate our approach and provide an example of hypothesis testing using our procedure, i.e., estimating the relation between predicted network ethnic homogeneity on Facebook and trust in institutions. In a comparison of our method with two other methods, we find that our method provides the most conservative tests of hypotheses. We discuss the promise of our approach and pinpoint future research directions. (shrink)

We introduce a new model construction for Martin-Löf intensional type theory, which is sound and complete for the 1-truncated version of the theory. The model formally combines, by gluing along the functor from the category of contexts to the category of groupoids, the syntactic model with a notion of realizability. As our main application, we use the model to analyse the syntactic groupoid associated to the type theory generated by a graph G, showing that it has the same homotopy type (...) as the free groupoid generated by G.

People narrating the experience of dysregulated anger after a brain injury call upon metaphor in patterned ways to help them make sense of their situation. Here, I analyze the use of the metaphor of the doubled self in a personal narrative of brain injury, and I situate this metaphor in its cultural history by analyzing Dr Jekyll and Mr Hyde and The Incredible Hulk as landmark moments in its development. A pattern of thought reflecting Seneca’s philosophy on the incompatibility of (...) anger with rational selfhood emerges. I discuss implications for the way we care for people struggling with post-brain-injury anger. (shrink)

Projet En développant son « empirisme constructif », Bas Van Fraassen est devenu une référence incontournable pour la philosophie des sciences contemporaine. Après la vague de critiques qui, vers les années 1960, avait fait perdre à l'empirisme logique sa prédominance dans le champ des idées, le réalisme scientifique semblait s'être imposé comme le seul compte rendu acceptable du travail et des orientations de la recherche. Quine avait beau énoncer ce que pourrait être un empirisme affranchi de ses deux « dogmes (...) » (l'intangibilité de la distinction vérités analytiques / vérités synthétiques, et la réduction des constructions aux « faits »), le programme d'une philosophie des sciences empiriste renouvelée restait à l'état d'esquisse. Mais par trois ouvrages successifs, Scientific Image (1980), Laws and symmetry (1989), et Quantum mechanics an empiricist view (1991), Van Fraassen a posé les bases d'un empirisme viable, parce que capable de prendre en charge la plupart des spécificités dont se prévaut le réalisme contre l'empirisme classique ou logique, et de rendre raison des développements les plus actuels de la physique. Contre l'empirisme classique ou logique, les réalistes font d'abord valoir que la réduction de toute réalité et de tout acte de référence aux phénomènes, ne rend justice ni à la pratique du langage courant ni à celle des sciences. Lorsque quelqu'un procède à une dénomination, il ne cherche pas à désigner par là une tranche d'apparaître, ou quelque ensemble fini et répertorié d'apparitions; il pointe vers "quelque chose" dont les modalités de manifestation sans fin assignable sont pour partie anticipées et pour partie ouvertes. De même, quand un chercheur scientifique parle de l'objet de ses investigations, il ne limite pas son discours à un ensemble fini de résultats d'expérience obtenus sous des conditions instrumentales actuellement disponibles; il renvoie à une entité dont la variété des manifestations futures est prévue aussi complètement que possible (et avec un succès croissant) par des cadres conceptuels et théoriques révisables. Face à cette objection, Van Fraassen fait jouer un rôle capital aux modèles dans sa version de l'empirisme.. (shrink)

What is empiricism and what could it be? Bas . van Fraassen, one of the world’s foremost contributors to philosophical logic and the philosophy of science, here undertakes a fresh consideration of these questions and offers a program for renewal of the empiricist tradition. The empiricist tradition is not and could not be defined by common doctrines, but embodies a certain stance in philosophy, van Fraassen says. This stance is displayed first of all in a searing, recurrent critique of metaphysics, (...) and secondly in a focus on experience that requires a voluntarist view of belief and opinion. Van Fraassen focuses on the philosophical problems of scientific and conceptual revolutions and on the not unrelated ruptures between religious and secular ways of seeing or conceiving of ourselves. He explores what it is to be or not be secular and points the way toward a new relationship between secularism and science within philosophy. (shrink)

We give an introduction to Turing categories, which are a convenient setting for the categorical study of abstract notions of computability. The concept of a Turing category first appeared in the work of Longo and Moggi; later, Di Paolo and Heller introduced the closely related recursion categories. One of the purposes of Turing categories is that they may be used to develop categorical formulations of recursion theory, but they also include other notions of computation, such as models of combinatory logic (...) and of the lambda calculus. In this paper our aim is to give an introduction to the basic structural theory, while at the same time illustrating how the notion is a meeting point for various other areas of logic and computation. We also provide a detailed exposition of the connection between Turing categories and partial combinatory algebras and show the sense in which the study of Turing categories is equivalent to the study of PCAs.

The story of how Perrin’s experimental work established the reality of atoms and molecules has been a staple in (realist) philosophy of science writings (Wesley Salmon, Clark Glymour, Peter Achinstein, Penelope Maddy, …). I’ll argue that how this story is told distorts both what the work was and its significance, and draw morals for the understanding of how theories can be or fail to be empirically grounded.

Metaphysicians speak of laws of nature in terms of necessity and universality; scientists, in terms of symmetry and invariance. In this book van Fraassen argues that no metaphysical account of laws can succeed. He analyzes and rejects the arguments that there are laws of nature, or that we must believe there are, and argues that we should disregard the idea of law as an adequate clue to science. After exploring what this means for general epistemology, the author develops the empiricist (...) view of science as a construction of models to represent the phenomena. (shrink)

This study analyzes the metaphoric and metonymic nature ofbaş/kafa‘head’ in Turkish idiomatic expressions from a cognitive linguistic perspective. The database for the study is composed of idioms containing the two head-denoting wordsbaşandkafa. Idioms and their definitions are analyzed in terms of their figurative uses of abstract concepts, and the conceptual metaphors and metonymies are identified. Findings are examined under five categories: head as the representative of the person, the seat of mental faculties, the locus of emotions, the sign of superiority/power, (...) and the sign of value. The study proposes a cultural model in which the image schemaswhole-part,containmentandverticalityplay a key role, and reveals cross-cultural similarities and differences in the conceptualization ofhead. The study also provides further support for the embodiment thesis, and underscores the impact of cultural processes in shaping the way the body is conceptualized. (shrink)

Vague subjective probability may be modeled by means of a set of probability functions, so that the represented opinion has only a lower and upper bound. The standard rule of conditionalization can be straightforwardly adapted to this. But this combination has difficulties which, though well known in the technical literature, have not been given sufficient attention in probabilist or Bayesian epistemology. Specifically, updating on apparently irrelevant bits of news can be destructive of one’s explicitly prior expectations. Stability of vague subjective (...) opinion appears to need a more complex model. (shrink)

A general form is proposed for epistemological theories, the relevant factors being: the family of epistemic judgments, the epistemic state, the epistemic commitment , and the family of possible epistemic inputs . First a simple theory is examined in which the states are probability functions, and the subject of probability kinematics introduced by Richard Jeffrey is explored. Then a second theory is examined in which the state has as constituents a body of information and a recipe that determines the accepted (...) epistemic judgments on the basis of this corpus. Through an examination of several approaches to the statistical syllogism, a relation is again established with Jeffrey's generalized conditionalization. (shrink)

The modal interpretation of quantum mechanics has two variants: the Copenhagen variant (CV) and the anti-Copenhagen variant (ACV). Healey uses the Bell-Wigner locality condition to criticize the latter, which I do not advocate. 2 The conclusions of Healey's admirably written article are therefore welcome to me. But if I had wished to advocate the ACV, I do not think that his arguments would have dissuaded me. Specifically, as I shall explain, we should distinguish between Physical Locality and Metaphysical Locality. The (...) first principle is unexceptionable, but Healey needs the second for his reductio. At the end I shall briefly indicate why I reject the ACV and advocate instead the Copenhagen variant.

Students using Ritalin in preparation for their exams is a hotly debated issue, while meditating or drinking coffee before those same exams is deemed uncontroversial. However, taking Ritalin, meditating and drinking coffee or even education in general, can all be considered forms of cognitive enhancement. Although social acceptance might change in the future, it is interesting to examine the current reasons that are used to distinguish cases deemed problematic or unproblematic. Why are some forms of cognitive enhancement considered problematic, while (...) others are not? In this paper, we consider cognitive enhancement as the amplification or extension of core capacities of the mind, using augmentation or improvements of our information-processing systems. We will analyse cognitive enhancement in an educational setting in order to clarify the fuzzy distinction between problematic and unproblematic forms of cognitive enhancement. We will show that the apparent distinction made by many people between problematic and unproblematic enhancement is not based on any fundamental difference between these two categories. (shrink)

Science tends to find a solution to the problem of the unreliability of human perception by understanding objectivity as the absence of subjectivity. However, from a phenomenological point of view, subjectivity is not so much a problem as an inevitable starting-point. That does not mean that the problem of the correctness of people’s accounts of their own perceptions is no problem at all—in fact the problem is so great that the authority of a person’s knowledge of his or her own (...) mind can be doubted. The problem of subjectivity can only be solved when it is related to the problem of interpretation. Analyses of narratives are interpretations of interpretations. The phenomenologist must make sure that the data he or she analyses are lived interpretations and not interpretations of interpretations. (shrink)
