: Results of a search for the electroweak associated production of charginos and next-to-lightest neutralinos, pairs of charginos or pairs of tau sleptons are presented. These processes are characterised by final states with at least two hadronically decaying tau leptons, missing transverse momentum and low jet activity. The analysis is based on an integrated luminosity of 20.3 fb−1 of proton-proton collisions at recorded with the ATLAS experiment at the Large Hadron Collider. No significant excess is observed with respect to the (...) predictions from Standard Model processes. Limits are set at 95% confidence level on the masses of the lighter chargino and next-to-lightest neutralino for various hypotheses for the lightest neutralino mass in simplified models. In the scenario of direct production of chargino pairs, with each chargino decaying into the lightest neutralino via an intermediate tau slepton, chargino masses up to 345 GeV are excluded for a massless lightest neutralino. For associated production of mass-degenerate charginos and next-to-lightest neutralinos, both decaying into the lightest neutralino via an intermediate tau slepton, masses up to 410 GeV are excluded for a massless lightest neutralino.[Figure not available: see fulltext.].

Cauchy’s contribution to the foundations of analysis is often viewed through the lens of developments that occurred some decades later, namely the formalisation of analysis on the basis of the epsilon-delta doctrine in the context of an Archimedean continuum. What does one see if one refrains from viewing Cauchy as if he had read Weierstrass already? One sees, with Felix Klein, a parallel thread for the development of analysis, in the context of an infinitesimal-enriched continuum. One sees, with Emile Borel, (...) the seeds of the theory of rates of growth of functions as developed by Paul du Bois-Reymond. One sees, with E. G. Björling, an infinitesimal definition of the criterion of uniform convergence. Cauchy’s foundational stance is hereby reconsidered. (shrink)

A construction of the real number system based on almost homomorphisms of the integers $\mathbb {Z}$ was proposed by Schanuel, Arthan, and others. We combine such a construction with the ultrapower or limit ultrapower construction to construct the hyperreals out of integers. In fact, any hyperreal field, whose universe is a set, can be obtained by such a one-step construction directly out of integers. Even the maximal (i.e., On -saturated) hyperreal number system described by Kanovei and Reeken (2004) and independently (...) by Ehrlich (2012) can be obtained in this fashion, albeit not in NBG . In NBG , it can be obtained via a one-step construction by means of a definable ultrapower (modulo a suitable definable class ultrafilter). (shrink)

We examine Paul Halmos’ comments on category theory, Dedekind cuts, devil worship, logic, and Robinson’s infinitesimals. Halmos’ scepticism about category theory derives from his philosophical position of naive set-theoretic realism. In the words of an MAA biography, Halmos thought that mathematics is “certainty” and “architecture” yet 20th century logic teaches us is that mathematics is full of uncertainty or more precisely incompleteness. If the term architecture meant to imply that mathematics is one great solid castle, then modern logic tends to (...) teach us the opposite lesson, namely that the castle is floating in midair. Halmos’ realism tends to color his judgment of purely scientific aspects of logic and the way it is practiced and applied. He often expressed distaste for nonstandard models, and made a sustained effort to eliminate first-order logic, the logicians’ concept of interpretation, and the syntactic vs semantic distinction. He felt that these were vague, and sought to replace them all by his polyadic algebra. Halmos claimed that Robinson’s framework is “unnecessary” but Henson and Keisler argue that Robinson’s framework allows one to dig deeper into set-theoretic resources than is common in Archimedean mathematics. This can potentially prove theorems not accessible by standard methods, undermining Halmos’ criticisms. (shrink)

This paper is an attempt to solve the following problem: given a logic, how to turn it into a paraconsistent one? In other words, given a logic in which ex falso quodlibet holds, how to convert it into a logic not satisfying this principle? We use a framework provided by category theory in order to define a category of consequence structures. Then, we propose a functor to transform a logic not able to deal with contradictions into a paraconsistent one. Moreover, (...) we study the case of paraconsistentization of propositional classical logic. (shrink)

This paper analyzes the problem of implication and attempts to characterize conditionals by a criterion of adequacy. A definition of implication based on the notion of limit of an infinite sequence is proposed.

Some strategies to turn any logic into a paraconsistent system are examined. In the environment of universal logic, we show how to paraconsistentize logics at the abstract level using a transformation in the class of all abstract logics called paraconsistentization by consistent sets. Moreover, by means of the notions of paradeduction and paraconsequence we go on applying the process of changing a logic converting it into a paraconsistent system. We also examine how this transformation can be performed using multideductive abstract (...) logics. To conclude, the conceptual notion paraconsistent orbit of a logic is proposed. (shrink)

Departing from basic concepts in abstract logics, this paper introduces two concepts: conjunctive and disjunctive limits. These notions are used to formalize levels of modal operators.

Henri Bergson is primarily known for his work on time, memory, and creativity. His equally innovative interventions into politics and religion have, however, been neglected or dismissed until now. In the first book in English dedicated to Bergson as a political thinker, leading Bergson scholars illuminate his positions on core concerns within political philosophy: the significance of emotion in moral judgment, the relationship between biology and society, and the entanglement of politics and religion. Ranging across Bergson's writings but drawing mainly (...) on his last book, _The Two Sources of Morality and Religion_, the contributors consider Bergson's relevance to contemporary discussions of human rights, democratic pluralism, and environmental ethics. _Contributors._ Keith Ansell-Pearson, G.

Cauchy's sum theorem is a prototype of what is today a basic result on the convergence of a series of functions in undergraduate analysis. We seek to interpret Cauchy’s proof, and discuss the related epistemological questions involved in comparing distinct interpretive paradigms. Cauchy’s proof is often interpreted in the modern framework of a Weierstrassian paradigm. We analyze Cauchy’s proof closely and show that it finds closer proxies in a different modern framework.

© 2014, The Author. A search for supersymmetry in events with large missing transverse momentum, jets, at least one hadronically decaying tau lepton and zero or one additional light leptons, has been performed using 20.3fb−1of proton-proton collision data at √ s= 8 TeV recorded with the ATLAS detector at the Large Hadron Collider. No excess above the Standard Model background expectation is observed in the various signal regions and 95% confidence level upper limits on the visible cross section for new (...) phenomena are set. The results of the analysis are interpreted in several SUSY scenarios, significantly extending previous limits obtained in the same final states. In the framework of minimal gauge-mediated SUSY breaking models, values of the SUSY breaking scale Λ below 63 TeV are excluded, independently of tan β. Exclusion limits are also derived for an mSUGRA/CMSSM model, in both the R-parity-conserving and R-parity-violating case. A further interpretation is presented in a framework of natural gauge mediation, in which the gluino is assumed to be the only light coloured sparticle and gluino masses below 1090 GeV are excluded.

The article examines epistemological and ontological underpinnings of reasearch performed by means of magnetic resonance imaging and functional magnetic resonance imaging. It takes as its guiding line the important distinction between instruments and apparatuses drawn by Rom Harré. According to Harré, instruments such as barometers or thermometers do not cause the states they measure into existence. Apparatuses, in contradistinction, cause material states into existence to begin with, whereby theses states are subsequently processed according to suitable methods. Thus, when the objects (...) of examination are subjected to 2 or more Tesla in fMRI, a strength of magnetic field never occuring in earthly nature, technical means literally create the states to be examined. Close examination of the functioning of MRI and fMRI indicates that brain states, e.g., are not simply read, or perceived as degrees of temperature are read on scale. Hence, one does not see any mental funtion when looking at fMRI outputs, for the visible output has been semantically processed on the basis of invisible quantum mechanical processes that have undergone translations into digital data caused by the fMRI device itself.

Gilberto Freyre, the great Brazilian historian and sociologist, described Brazil as a ‘racial paradise’, a place where different races and nationalities have come to live together in a sort of ‘racial democracy’. The literature on this topic has become extensive as anthropologists, social scientists and historians felt the need to either prove or disprove such a claim. The argument that Brazil is a racial paradise or democracy is certainly romantic, even utopian; but it is true that Brazil has not experienced (...) the sort of racial friction that has been found in places such as South Africa (e.g. apartheid) or the USA (e.g. segregation laws). This article analyses interculturalism and non-formal education in Brazilian society from the perspective of Martin Buber's philosophy of dialogue and demonstrates some of the advantages interculturalism has over multiculturalism. We further suggest that the example of modern and contemporary Brazil follows Martin Buber in ‘pointing the way’ for other countries and for other societies and cultures. (shrink)

Les neurosciences modernes, notamment les découvertes récentes de la recherche sur le cerveau, réclament de plus en plus un changement radical dans leurs tenants et aboutissants philosophiques, loin en particulier de l’anthropologie théologique du Christianisme qui s’appuya pendant de longs siècles sur la conception philosophique dualiste de l’union entre corps et âme. Dans cet essai, A. Ganoczy veut d’abord exposer des acquis de la recherche sur le cerveau qui entraînent, chez les uns, une conception matérialiste et, chez les autres, une (...) description non matérialiste de la personne humaine, les deux camps s’accordant à se situer dans un contexte strictement évolutionniste. S’appuyant sur les travaux et écrits de J.-P. Changeux et Gerhard Vollmer, pour les premiers, de John C. Eccles et Antonio R. Damasio, pour les seconds, A. G. examine les thèses et hypothèses de ces scientifiques qui n’hésitent pas à franchir les frontières évidentes de leurs compétences pour établir une nouvelle anthropologie, sans même une visée ouvertement et méthodiquement interdisciplinaire.Modern neuroscience, notably the recent discoveries of research on the brain, increasingly call for a radical change in their positions and philosophical conclusions, which are particularly distant from the theological anthropology of Christianity, which depended for many centuries on a duelist philosophical conception of the union between body and soul. In this essay, A. Ganoczy wishes first of all to present the results of research on the brain that result in a materialist conception for some, and for others a non-materialist description of the human person. The two camps agreed to place themselves in a strictly evolutionist context. Using the work and writings of J.-P. Changeux and Gerhard Vollmer for the first camp, John C. Eccles and Antonio R. Damasio for the second camp, A. G. examines the theses and hypotheses of these scientists who did not hesitate to go beyond the evident boundaries of their competencies to establish a new anthropology, without even having an openly, methodologically interdisciplinary outlook.

The purpose of this study was to examine the effectiveness of a neuro-meditation program to support nurses during the COVID-19 pandemic. Forty-five nurses were classified into three groups based on their systolic blood pressure: normotensive, hypertensive and control. Using a parallel, randomly controlled design across a 4-week period, 10 × 30-min sessions using the Rebalance© Impulse were completed. Sleep was assessed by wrist actigraphy and subjective sleep questionnaires; perceived sleep quality, Ford Insomnia Response to Stress Test questionnaire and the Spiegel (...) Sleep Quality questionnaire. Blood pressure, resting heart rate, mean heart rate, heart rate variability index, cortisol, and alpha-amylase were also measured. Statistical analysis was completed using factorial ANOVA. Sleep improved in the G-hyp group; SSQ ; perceived sleep quality ; sleep efficiency and fragmentation index. In the G-nor group, sleep was improved to a lesser extent; perceived sleep quality. A significant time–group interaction was reported in resting heart rate, systolic blood pressure, and diastolic blood pressure with these measures being significantly reduced in the G-hyp group. RMSSD increased in the G-nor group. This initial evidence suggests that neuro-meditation reduces excessive sympathetic activity, promoting enhanced sleep quality and autonomic control during periods of increased work-related stress.Clinical Trial RegistrationThe study was conducted at Bioesterel, Sophia-Antipolis, France as a clinical trial: Neuro-meditation improves sleep quality, https://www.drks.de/ui_data_web/DrksUI.html?locale=en, DRKS00025731.

O tema do reconhecimento é central na obra de G. W. F Hegel. Classicamente, situa-se na figura da luta entre o senhor e o escravo, na Fenomenologia do Espírito. A intersubjetividade e, portanto, o reconhecimento, na obra hegeliana, colocam o seguinte problema: como é possível construir uma interpretação que supere o conceito de subjetividads moderna, positivado pela prática jusfilosófica, vindo a garantir um novo paradigma fundado na intersubjetividade e, portanto, pressupondo a teoria hegeliana do reconhecimento? Em primeiro lugar, analisa-se o (...) desejo antropológico de reconhecimento como fonte da idéia de justiça em A. Kojéve. Em seguida, apresenta-se, segundo 0 mesmo autor, a fenomenologia da justiça, que parte do princípio de que o desejo, conforme Hegel, quer o reconhecimento, sendo este a fonte última da idéia de justiça. Kojéve expõe fenomenologicamente a idéia de justiça, em três momentos: a justiça aristocrática ou a igualdade, a justiça burguesa ou a equivalência e a justiça cidadã ou a equidade. Finalmente, conclui-se que o reconhecimento intersubjetivo ocorre em vários níveis de mediação social, jurídica e política. Assim, na complexidade da sociedade mundializada, produzir uma hermenêutica jusfilosófica de cunho intersubjetivo encontra, na teoria hegeliana do reconhecimento, um fundamental pressuposto epistemológico.

An understanding of the relationship between metaphysics and natural philosophy - or, as we might now say, between philosophy and science - is fundamental to understanding the rise of the "new science" of the seventeenth century. Twentieth-century scholarship on this relationship has been dominated by the thoughbt of Ernst Cassirer, E. A. Burtt, A. N. Whitehead, and Alexandre Koyre. These authors found a common core in the mathematization of nature, which they ascribed to a common Platonic or Pythagorean metaphysical (...) presupposition, on the part of Copernicus, Kepler, Galileo, and Descartes, that the book of nature is written in mathematical characters. Taking Burtt as its primary stalking horse, this chapter challenges this view by finding significant differences in the relations to metaphysics of major actors such as those just named. It does this in part by recognizing that, in the seventeenth century, metaphysics was an intellectual practice that one engaged in wittingly. By contrast, Burtt adopted a historiographical approach in which metaphysics consists of the nonempirical presupposition of an age (a position advanced by R. G. Collingwood). That approach, although valid within its limits, distorts or omits from consideration the witting practice of metaphysics by figures such as Kepler and Descartes. And it makes metaphysicians of Copernicus and Galileo, who are better classified as a mathematical astronomer and a mathematical natural philosopher and writer on astronomy. The chapter ends with some reflections on purportedly aphilosophical history of science. (shrink)

This collection of six essays centers on Professor Koyre;'s great theme: the relative importance of metaphysics and observation, with controlled experiment a kind of marriage between the two.

At the time of his death, Alexandre Koyre; was a professor at the Ecole Pratique des (...) Hautes Études (Sorbonne) and a memeber of the Institute for Advanced Study in Princeton. (shrink)

In lieu of an abstract, here is a brief excerpt of the content: Hypatia 14.4 (1999) 186-191 -/- [Access article in PDF] Simone De Beauvoir: a Critical Reader. Edited by Elizabeth Fallaize. London and New York: Routledge, 1998. As this special volume attests, there has been a recent resurgence of interest in Simone de Beauvoir. A number of books on her have been published in the last several years. However, Elizabeth Fallaize's book, Simone de Beauvoir: A Critical Reader (1998), occupies (...) a special niche. Many of its essays are excerpts from studies done of Beauvoir's work before this latest renaissance. Some of these studies are not in print in the United States. Some are perhaps unfamiliar to present-day readers or those from different disciplines. In addition, the articles reprinted here are otherwise not easily accessible. Fallaize has performed an important service by gathering them all in one place and by carefully editing, presenting, and, in some cases, translating them. -/- The book is divided into three sections, the first entitled "Readings of The Second Sex." Aside from Judith Okely's piece that assesses Beauvoir's chapter on myths from an anthropological standpoint, the essays mainly address the philosophical aspects of this work. Beauvoir herself of course swore that she was not a philosopher and that Jean-Paul Sartre's Being and Nothingness (1953) was the sole philosophical foundation for all her work. Some recent analyses have attempted to turn this picture on its head by arguing that Beauvoir was a central influence on, or even the origin of, the philosophical doctrines put forward in Being and Nothingness. None of the writers in this book addresses this issue. But two emphasize Beauvoir's intellectual independence from Sartre. -/- The Swedish scholar Eva Lundgren-Gothlin argues that Beauvoir turned to G. W. F. Hegel to find a satisfactory theoretical model with which to explain the subjugation of women (Lundgren-Gothlin's essay is taken from her book [End Page 186] Sex and Existence [1996]) . In opposition to other scholars, she argues that the French Hegelian Alexandre Kojève, not Sartre, influenced Beauvoir's interpretation of Hegel. Following Hegel and Kojève, Beauvoir envisioned a possible resolution to the struggle for recognition—reciprocal recognition—whereas Sartre's view of self-other relations in Being and Nothingness rules such reciprocity out. However, Lundgren-Gothlin judges, Beauvoir was not critical enough of the sexist presuppositions of Hegel's thought, citing the same pronouncements Beauvoir makes that subsequent feminists have criticized. -/- Another piece that stresses Beauvoir's philosophical originality is "Beauvoir: The Weight of Situation," taken from Sonia Kruks's book Situation and Human Existence (1990). For some time, Kruks has been doing excellent work placing Beauvoir within the wider phenomenological tradition. In this piece, she argues that, starting with the early essay Pyrrhus et Cinéas (1944) and culminating in The Second Sex (1989), Beauvoir elaborated a more nuanced position on the nature and extent of human freedom than Sartre did in Being and Nothingness. According to Beauvoir, human freedom, which Sartre dramatically proclaims is absolute, can under some conditions, notably conditions of severe oppression, "be reduced to no more than a suppressed potentiality" (Fallaize 1998, 57). In The Second Sex, Beauvoir definitively breaks with the philosophical framework of Being and Nothingness by implying that a woman's situation is a general one, not individually self-constituted, and one that she cannot transcend by an act of free choice. The phenomenology of Maurice Merleau-Ponty provides a better foundation for Beauvoir's conception of subjectivity as socially mediated and embodied than does Sartre's philosophy, Kruks suggests. -/- Another piece in this section, Judith Butler's landmark essay "Sex and Gender in Simone de Beauvoir's Second Sex" (1986), highlights Beauvoir's philosophical originality in a different way. In her introduction, Fallaize points out how this essay served as a foundation for Butler's own subsequent work on a performative theory of gender. Butler argues that Beauvoir's claim that one is not born but becomes a woman implies that gender is socially constructed and not natural, as people have insisted for centuries. But to the extent that we become women, gender is not something... (shrink)
