The debate between realism and antirealism has been central in the general philosophy of science of the last decades. But ever since the heydays of the debate in the 1980s, there have been authors who have tried to argue for the overcoming or dissolution of the debate itself, by proposing a position that is neither realist nor antirealist. Prominent among these is Joseph Rouse (Rouse 1987). Yet, Jeff Kochan has recently argued that Rouse, despite his efforts to transcend the realism/antirealism (...) debate through his universal practical hermeneutics, ends up an implicit realist (Kochan 2011). Kochan furthermore uses this as an occasion to rectify what he sees as Rouse’s influential but misleading interpretation of .. (shrink)

More Urban Myths About Learning and Education: Challenging Eduquacks, Extraordinary Claims, and Alternative Facts examines common beliefs about education and learning that are not supported by scientific evidence before using research to reveal the truth about each topic. The book comprises sections on educational approaches, curriculum, educational psychology, and educational policy, concluding with a critical look at evidence-based education itself. Does playing chess improve intelligence? Should tablets and keyboards replace handwriting? Is there any truth to the 10,000-hour rule for expertise? (...) In an emerging, conversational style, authors Pedro de Bruyckere, Paul A. Kirschner, and Casper D. Hulshof tackle a set of pervasive myths, effectively separating fact from fiction in learning and education--back cover. (shrink)

We study punctual categoricity on a cone and intrinsically punctual functions and obtain complete structural characterizations in terms of model-theoretic notions. As a corollary, we answer a question of Bazhenov, Downey, Kalimullin, and Melnikov by showing that relational structures are not punctually universal. We will also apply this characterisation to derive an algebraic characterisation of relatively punctually categorical mono-unary structures.

There is a global shortage of nurses that affects healthcare delivery, which will be exacerbated with the increasing demand for healthcare professionals by the aging population. The growing shortage requires an ethical exploration on the issue of nurse migration. In this article, we discuss how migration respects the autonomy of nurses, increases cultural diversity, and leads to improved patient satisfaction and health outcomes. We also discuss the potential for negative impacts on public health infrastructures, lack of respect for cultural diversity, (...) and ethical concerns related to autonomy and justice, including coercion and discrimination. This analysis is written from a rights-based ethics approach by referring to rights held by nurses and patient populations. Nurse migration highlights conflicts between nurses and between nurses and healthcare systems. Increased awareness of ethical challenges surrounding nurse migration must be addressed to enhance the well-being of nurses and patient populations. (shrink)

Working toward showing the decidability of the $\forall \exists $ -theory of the ${\Sigma ^0_2}$ -enumeration degrees, we prove that no so-called Ahmad pair of ${\Sigma ^0_2}$ -enumeration degrees can join to ${\mathbf 0}_e'$.

Defining the degree of categoricity of a computable structure ${\mathcal{M}}$ to be the least degree d for which ${\mathcal{M}}$ is d-computably categorical, we investigate which Turing degrees can be realized as degrees of categoricity. We show that for all n, degrees d.c.e. in and above 0 (n) can be so realized, as can the degree 0 (ω).

We analyze the degree spectra of structures in which different types of immunity conditions are encoded. In particular, we give an example of a structure whose degree spectrum coincides with the hyperimmune degrees. As a corollary, this shows the existence of an almost computable structure of which the complement of the degree spectrum is uncountable.

A Turing degreedis the degree of categoricity of a computable structure${\cal S}$ifdis the least degree capable of computing isomorphisms among arbitrary computable copies of${\cal S}$. A degreedis the strong degree of categoricity of${\cal S}$ifdis the degree of categoricity of${\cal S}$, and there are computable copies${\cal A}$and${\cal B}$of${\cal S}$such that every isomorphism from${\cal A}$onto${\cal B}$computesd. In this paper, we build a c.e. degreedand a computable rigid structure${\cal M}$such thatdis the degree of categoricity of${\cal M}$, butdis not the strong degree of categoricity (...) of${\cal M}$. This solves the open problem of Fokina, Kalimullin, and Miller [13].For a computable structure${\cal S}$, we introduce the notion of the spectral dimension of${\cal S}$, which gives a quantitative characteristic of the degree of categoricity of${\cal S}$. We prove that for a nonzero natural numberN, there is a computable rigid structure${\cal M}$such that$0\prime$is the degree of categoricity of${\cal M}$, and the spectral dimension of${\cal M}$is equal toN.

Marsilio Ficino’s fame as a translator, not least due to his contributions to theology and the development of hermeticism, has already been established by Frances Yates and debated by Wouter Hanegraaff. For each of his translations of Greek texts, Ficino wrote a preface to guide and to manipulate the reader. This paper presents an analysis of the auctoritas in the paratext of the Corpus Hermeticum, analyzing it as a rhetorical device used by Ficino to express his ideas, particularly the role (...) of Hermes Trismegistus. Ficino used his rhetorical skill not only to translate from Greek to Latin but also to support his theories in commentaries, letters, or, in this case, prefaces. (shrink)

We give several new characterizations of the continuous enumeration degrees. The main one proves that an enumeration degree is continuous if and only if it is not half of a nontrivial relativized $\mathcal {K}$ -pair. This leads to a structural dichotomy in the enumeration degrees.

We extend the limitwise monotonicity notion to the case of arbitrary computable linear ordering to get a set which is limitwise monotonic precisely in the non‐computable degrees. Also we get a series of connected non‐uniformity results to obtain new examples of non‐uniformly equivalent families of computable sets with the same enumeration degree spectrum.

We show that the Δ0 2 enumeration degrees are dense. We also show that for every nonzero n-c. e. e-degree a, with n≥ 3, one can always find a nonzero 3-c. e. e-degree b such that b < a on the other hand there is a nonzero ωc. e. e-degree which bounds no nonzero n-c. e. e-degree.

We introduce a hierarchy of sets which can be derived from the integers using countable collections. Such families can be coded into countable algebraic structures preserving their algorithmic properties. We prove that for different finite levels of the hierarchy the corresponding algebraic structures have different classes of possible degree spectra.

We prove that the degree structures of the d.c.e. and the 3-c.e. Turing degrees are not elementarily equivalent, thus refuting a conjecture of Downey. More specifically, we show that the following statement fails in the former but holds in the latter structure: There are degrees f > e > d > 0 such that any degree u ≤ f is either comparable with both e and d, or incomparable with both.

This special issue aims to explore and investigate a new subfield, namely experimental philosophy of medicine. Whereas experimental philosophy is relatively new on the philosophical block, some of its takes and findings have already shaped central debates in ethics, philosophy of action, philosophy of language, and epistemology. Interestingly, the approach of this program was for a long time almost wholly ignored within bioethics and philosophy of medicine—although this seems to have changed somewhat recently. In this introduction, we briefly sketch the (...) program of experimental philosophy and how it can be used to shed philosophical light on issues in the philosophy of medicine. (shrink)

For a computable structure $\mathcal {M}$, the categoricity spectrum is the set of all Turing degrees capable of computing isomorphisms among arbitrary computable copies of $\mathcal {M}$. If the spectrum has a least degree, this degree is called the degree of categoricity of $\mathcal {M}$. In this paper we investigate spectra of categoricity for computable rigid structures. In particular, we give examples of rigid structures without degrees of categoricity.

ABSTRACTThere is a growing body of literature describing conceptual frameworks for working with participatory visual methods. Through a global health lens, this paper examines some key themes within these frameworks. We reflect on our experiences of working with with an array of PVM to engage community members in Vietnam, Kenya, the Philippines and South Africa in biomedical research and public health. The participants that we have engaged in these processes live in under-resourced areas with high prevalence of communicable and non-communicable (...) diseases. Our paper describes some of the challenges that we have encountered while using PVM to foster knowledge exchange, build relationships and facilitate change among individuals and families, community members, health workers, biomedical scientists and researchers. We consider multiple ethical situations that have arisen through our work and discuss the ways in which we have navigated and negotiated them. We offer our reflections and learning from facil...

The survey contains a detailed discussion of methods and results in the new emerging area of online “punctual” structure theory. We also state several open problems.

A structure is automatic if its domain, functions, and relations are all regular languages. Using the fact that every automatic structure is decidable, in the literature many decision problems have been solved by giving an automatic presentation of a particular structure. Khoussainov and Nerode asked whether there is some way to tell whether a structure has, or does not have, an automatic presentation. We answer this question by showing that the set of Turing machines that represent automata-presentable structures is ${\rm{\Sigma (...) }}_1^1 $-complete. We also use similar methods to show that there is no reasonable characterisation of the structures with a polynomial-time presentation in the sense of Nerode and Remmel. (shrink)

Neste artigo, no intuito de nos inscrevermos em uma reflexão mais abrangente acerca dos negacionismos contemporâneos, com foco no “negacionismo histórico”, que se sustenta por processos de falseamento e homogeneização da história e das memórias, buscamos seguir o seguinte roteiro de reflexão analítica: i) tratar da escrita da história, abordando a produção de memórias, as políticas de esquecimento e o falseamento discursivo da história; ii) traçar um panorama acerca da escrita da história e da produção de memórias da ditadura civil-militar (...) brasileira, observando, de um lado, a produção discursiva nos campos escolar, jornalístico e “de história”, como formas de manifestação e promoção da memória oficial do regime, e, de outro, a construção das políticas institucionais de memória, com foco nas comissões de verdade, como mecanismos de instituição de regimes de dizibilidade sustentados por memórias-outras; iii) como eixo analítico-conclusivo, traçar uma reflexão que vai da negação da história à formação do autoritarismo contemporâneo, tomando como exemplo a violência contra os povos originários. Inscrevemo-nos, para dar cabo a esta discussão, na perspectiva arqueogenealógica dos Estudos Discursivos Foucaultianos, a partir da mobilização de um arcabouço teórico-metodológico que permite a análise dos processos de formação dos enunciados e dos discursos e, fundamentalmente, uma crítica reflexiva do presente.

Propose une hypothèse originale sur les sources de la pensée de Bergson et sa portée profonde, sur le mouvement de son oeuvre et la méthode qui s'impose pour la lire, sur la place de sa philosophie dans l'histoire.

It is proved that for every countable structure and a computable successor ordinal α there is a countable structure which is ‐least among all countable structures such that is Σ‐definable in the αth jump. We also show that this result does not hold for the limit ordinal. Moreover, we prove that there is no countable structure with the degree spectrum for.

Recall that B is PA relative to A if B computes a member of every nonempty $\Pi ^0_1(A)$ class. This two-place relation is invariant under Turing equivalence and so can be thought of as a binary relation on Turing degrees. Miller and Soskova [23] introduced the notion of a $\Pi ^0_1$ class relative to an enumeration oracle A, which they called a $\Pi ^0_1{\left \langle {A}\right \rangle }$ class. We study the induced extension of the relation B is PA relative (...) to A to enumeration oracles and hence enumeration degrees. We isolate several classes of enumeration degrees based on their behavior with respect to this relation: the PA bounded degrees, the degrees that have a universal class, the low for PA degrees, and the ${\left \langle {\text {self}\kern1pt}\right \rangle }$ -PA degrees. We study the relationship between these classes and other known classes of enumeration degrees. We also investigate a group of classes of enumeration degrees that were introduced by Kalimullin and Puzarenko [14] based on properties that are commonly studied in descriptive set theory. As part of this investigation, we give characterizations of three of their classes in terms of a special sub-collection of relativized $\Pi ^0_1$ classes—the separating classes. These three can then be seen to be direct analogues of three of our classes. We completely determine the relative position of all classes in question. (shrink)

It is argued that John Bickle’s Ruthless Reductionism is flawed as an account of the practice of neuroscience. Examples from genetics and linguistics suggest, first, that not every mind-brain link or gene-phenotype link qualifies as a reduction or as a complete explanation, and, second, that the higher (psychological) level of analysis is not likely to disappear as neuroscience progresses. The most plausible picture of the evolving sciences of the mind-brain seems a patchwork of multiple connections and partial explanations, linking anatomy, (...) mechanisms and functions across different domains, levels, and grain sizes. Bickle’s claim that only the molecular level provides genuine explanations, and higher level concepts are just heuristics that will soon be redundant, is thus rejected. In addition, it is argued that Bickle’s recasting of philosophy of science as metascience explicating empirical practices, ignores an essential role for philosophy in reflecting upon criteria for reduction and explanation. Many interesting and complex issues remain to be investigated for the philosophy of science, and in particular the nature of interlevel links found in empirical research requires sophisticated philosophical analysis.

The paper provides a reconstruction of the notion of material Apriori while exhibiting the anti-Kantian inspiration and factual grounding thereof. The attempt is made to show that a non-formal Apriori obtains because the sensuous has a normative character; further, that the difference between material and formal eidetic laws is rooted in the difference between sensuous contents, given in experience, and intellectual contents, originating in activities of judgement. The material Apriori is not independent of all experience, since it is grounded on (...) sensuous eidetic contents and thus depends on the latter’s givenness and characteristics. It is thanks precisely to this ,contingency‘ that it has an ontological significance. (shrink)

Razón, poesía, historia.--La cuestión del estoicismo español.--El querer.

Hegel is most famous for his view that conflicts between contrary positions are necessarily resolved. Whereas this optimism, inherent in modernity as such, has been challenged from Kierkegaard onward, many critics have misconstrued Hegel's own intentions. Focusing on the Science of Logic, this transformative reading of Hegel on the one hand exposes the immense force of Hegel's conception of tragedy, logic, nature, history, time, language, spirit, politics, and philosophy itself. Drawing out the implications of Hegel's insight into tragic conflicts, on (...) the other hand, De Boer brings into play a form of negativity that allows us to understand why the entanglement of complementary positions always tends to turn into their conflict, but not necessarily into its resolution.

Un verbe exprime en français l'un des secrets de notre être et l'une des clés de notre époque maniaco-dépressive : ce verbe, c'est revivre. Il a deux sens que tout paraît opposer. Revivre, c'est en effet renaître, retrouver le sentiment d'être vivant et relié à autrui. Mais c'est aussi se laisser rattraper par "un passé qui ne passe pas » et se replier sur soi-même. Chacun de nous fait cette double expérience, souvent sans le savoir. Il faut pourtant la penser, (...) l'affronter, résister à ce qui nous enferme, accéder à ce qui nous délivre. Inventaire de nos blessures et de nos ressources, diagnostic du moment présent, parcours dans les idées et les oeuvres, ces propos renouent avec les actes les plus intenses de notre vie. Un art de vivre, c'est-à-dire de revivre, qui pourrait bien être le seul possible aujourd'hui. (4e de couv.). (shrink)

Neste texto, pretende-se investigar a apropriação das idéias de Foucault em textos de Jorge Larrosa, na medida em que essa apropriação contribui para a discussão da formação. Através da análise dos modos como a pedagogia é produtora de subjetividades, Larrosa pretende construir as bases de um método que permita avaliar exemplos pedagógicos concretos.

From classic aesthetic theories to fresh aesthetic methods, this volume is an accessible introduction to the main topics in contemporary aesthetics: the media-technological challenges, transcultural aesthetics and aesthetic methodology.

De Muralt's ambition is to carry out such 'historical' inquiries in the form of a structural analysis of philosophy, which he regards as a rigorous philosophical discipline - that is, as a science.
