ObjectiveTo prospectively study the cingulate cortex for the localization and role of the grasping action in humans during electrical stimulation of depth electrodes.MethodsAll the patients with intractable focal epilepsy and a depth electrode stereotactically placed in the cingulate cortex, as part of their pre-surgical epilepsy evaluation from 2015 to 2017, were included. Cortical stimulation was performed and examined for grasping actions. Post-implantation volumetric T1 MRIs were co-registered to determine the exact electrode position.ResultsFive patients exhibited contralateral grasping actions during electrical stimulation. (...) All patients had electrodes implanted in the ventral bank of the right cingulate sulcus adjacent to the vertical anterior commissure line. Stimulation of other electrodes in adjacent regions did not elicit grasping.ConclusionGrasping action elicited from a localized region in the mid-cingulate cortex directly supports the concept of the cingulate cortex being crucially involved in the grasping network. This opens an opportunity to explore this region with deep brain stimulation as a motor neuromodulation target for treatment in specific movement disorders or neurorehabilitation. (shrink)

Many of the discussions about conditionals can best be put as follows:can those conditionals that involve an entailment relation be formulatedwithin a formal system? The reasons for the failure of the classical approachto entailment have usually been that they ignore the meaning connectionbetween antecedent and consequent in a valid entailment. One of the firsttheories in the history of logic about meaning connection resulted from thestoic discussions on tightening the relation between the If- and the Then-parts of conditionals, which in this (...) context was called. This theory gave a justification for the validity of what we todayexpress through the formulae ¬ and ¬. Hugh MacColl and, more recently, Storrs McCall searched for a formal system in which the validity ofthese formulae could be expressed. Unfortunately neither of the resulting systems is very satisfactory. In this paper we introduce dialogical games with the help of a new connexive If-Then (), the structural rules of which allow the Proponent to develop winning strategies not only for the above-mentioned connexive theses but also for ¬ and ¬. Further on, we developthe corresponding tableau systems and conclude with some remarks on possibleperspectives and consequences of the dialogical approach to connexivity including the loss of uniform substitution leading to a new concept of logical form.

It may be tempting to think that given Nagel’s much-discussed bat argument in “What Is It Like to be a Bat?” (henceforth the Bat article), Nagel qua Nagel has conceived an argument against the very idea of physicalism. For example, Tye (1986 p. 7) argues that Nagel’s argument from the Bat-Phenomenology Analogy shows that the physicalist account of the mental phenomenon is incomplete. Churchland (1995 p. 196) conceives Nagel in a similar manner: “[from the Bat Argument] Nagel concludes that conscious (...) phenomena cannot be given a purely physical explanation”. McCullough (1988 pp. 2-3), without regret, is more direct on the issue: Nagel is against physicalism because the state of what-it-is-likeness “escapes the scientific net”. The same goes with Pereboom who argues that Thomas Nagel advances an argument that shows physicalist account of the phenomenal states are “inadequate” (1994 p. 314). The most recent article dealing with the Bat argument also makes it clear that physicalism does not feature in friendly terms in Nagel’s thinking (Nagasawa 2004). While Nagasawa claims to offer a new approach to Nagel’s Bat argument in that Aquinas’ seemingly disconnected argument about the divine omnipotence can answer Nagel’s resistance to physicalism, it is quite clear that Nagel is still being treated as an anti-physicalist. Now, of course, it’s fallacious to say that all these philosophers are alike in their takes on Nagel’s alleged anti-physicalist outlook but I hope it is uncontroversial to say here that they seem to share a common view of Nagel: On Nagel’s account of conscious mental states, physicalism is false because it fails to explain exactly what it is like to be in those states. In this essay, I wish to argue that Nagel’s treatment of physicalism as demonstrated in the Bat article is much more philosophically subtle than his detractors thought him to be. From the outset, let me begin by stating that Nagel is not characteristically a foe of physicalism as most of philosophers make him to be but Nagel in the Bat article could seem beproposing three challenges to physicalism as follows: (P1) physicalism is false, (P2) physicalism is unintelligible and (P3) physicalism remains to be made intelligible.

Recent literature on dialogical logic discusses the case of tonk and the notion harmony in the context of a rule-based theory of meaning. Now, since the publications of those papers, a dialogical version of constructive type theory (CTT) has been developed. The aim of the present paper is to show that, from the dialogical point of view, the harmony of the CTT- rules is the consequence of a more fundamental level of meaning characterized by the independence of players. We hope (...) that the following paper will contribute to a better understanding of the dialogical notion of meaning.La bibliografía reciente sobre lógica dialógica, estudia el caso de tonk y la noción de armonia en el contexto de una teoría del significado basado en reglas. Ahora bien, desde la publicación de tales textos, la teoría dialógica ha sido vinculada con la Teoría Constructiva de Tipos (CTT). El objetivo principal del presente artículo es mostrar que, desde un punto de vista dialógico, la armonía de las reglas de la CTT es consecuencia de un nivel más fundamental de significado caracterizado por la independencia de los jugadores. Esperamos que el presente trabajo contribuya a una mejor comprensión de la nocion dialógica de significado. (shrink)

The work of Hugh MacColl (1837–1909) suffered the same fate after his death as before it:despite being vaguely alluded to and in part even commended, on the whole it has remained an unknown quantity. Even worse, those of his ideas which have played a decisive role in the history of logic have been credited to his successors; this is especially the case with the definition of strict implication and the first formal development of formal modal logic. This paper takes an (...) initial step towards a rectification of this unfortunate misrepresentation, presenting a bibliography of MacColl’s most significant publications with particular regard to their reception.

This paper discusses the possibility of wealth adjustment through a credit network. The discussed credit network in this paper is a kind of loaning with no interest rate (its value is zero). It explains the influence of existence or inexistence of a cooperation originated from the credit network on wealth distribution and adjustment in an artificial society. To show how the wealth may distribute, environment agents in terms of their obtained wealth have been classified into ten wealth categories; thus, the (...) share of each category in terms of population has been determined. In addition, the survival of population in the environment has been studied. Findings and results show more balanced distribution of agents among the categories of wealth and higher survival of the population in the existence of the credit network. More over, the curve of population has fewer fluctuations. In other words, the population is more stable due to the ability of credit network in making more survival and stability in the population of environment in periods of time by providing the possibility of cooperation and wealth better distribution.

The Theme. Strong forcing axioms like Martin’s Maximum give a reasonably satisfactory structural analysis of $H(\omega _2)$. A broad program in modern Set Theory is searching for strong forcing axioms beyond $\omega _1$. In other words, one would like to figure out the structural properties of taller initial segments of the universe. However, the classical techniques of forcing iterations seem unable to bypass the obstacles, as the resulting forcings axioms beyond $\omega _1$ have not thus far been strong enough! However, (...) with his celebrated work on generalised side conditions, I. Neeman introduced us to a novel paradigm to iterate forcings. In particular, he could, among other things, reprove the consistency of the Proper Forcing Axiom using an iterated forcing with finite supports. In 2015, using his technology of virtual models, Veličković built up an iteration of semi-proper forcings with finite supports, hence reproving the consistency of Martin’s Maximum, an achievement leading to the notion of a virtual model.In this thesis, we are interested in constructing forcing notions with finitely many virtual models as side conditions to preserve three uncountable cardinals. The thesis constitutes six chapters and three appendices that amount to 118 pages, where Section 1 is devoted to preliminaries, and Section 2 is a warm-up about the scaffolding poset of a proper forcing. In Section 3, we present the general theory of virtual models in the context of forcing with sets of models of two types, where we, e.g., define the “meet” between two virtual models and prove its properties.The main results are joint with Boban Veličković, and partly appeared in Guessing models and the approachability ideal, J. Math. Log. 21 (2021).Pure Side Conditions. In Section 4, we use two types of virtual models (countable and large non-transitive ones induced by a supercompact cardinal, which we call Magidor models) to construct our forcing with pure side conditions. The forcing covertly uses a third type of models that are transitive. We also add decorations to the conditions to add many clubs in the generic $\omega _2$. In contrast to Neeman’s method, we do not have a single chain, but $\alpha $ -chains, for an ordinal $\alpha $ with $V_\alpha \prec V_\lambda $. Thus, starting from suitable large cardinals $\kappa <\lambda $, we construct a forcing notion whose conditions are finite sets of virtual models described earlier. The forcing is strongly proper, preserves $\kappa $, and has the $\lambda $ -Knaster property. The relevant quotients of the forcing are strongly proper, which helps us prove strong guessing model principles. The construction is generalisable to a ${<}\mu $ -closed forcing, for any given cardinal $\mu $ with $\mu ^{<\mu }=\mu <\kappa $.The Iteration Theorem. In Section 5, we use the forcing with pure side conditions to iterate a subclass of proper and $\aleph _2$ -c.c. forcings and obtain a forcing axiom at the level of $\aleph _2$. The iterable class is closely related to Asperó–Mota’s forcing axiom for finitely proper forcings.Guessing Model Principles. Section 6 encompasses the main parts of the thesis. We prove the consistency of the guessing principle $\mathrm {GMP}^+(\omega _3,\omega _1)$ that states for any cardinal ${\theta \geq \omega _3}$, the set of $\aleph _2$ -sized elementary submodels M of $H(\theta )$, which are the union of an $\omega _1$ -continuous $\in $ -chain of $\omega _1$ -guessing, I.C. models is stationary in $\mathcal P_{\omega _3}(H(\theta ))$. The consistency and consequences of this principle are demonstrated in the following diagram. We also prove that one can obtain the above guessing models in a way that the $\omega _1$ -sized $\omega _1$ -guessing models remain $\omega _1$ -guessing model in any outer transitive model with the same $\omega _1$, and we denote this principle by $\rm{SGMP}^+(\omega_3,\omega_1)$.In the following diagram, $\mathrm{TP}$ stands for the tree property; $w\mathrm{KH}$ stands for the weak Kurepa Hypothesis; $\mathrm{MP}$ stands for Mitchell property, i.e., the approachability ideal is trivial modulo the nonstationary ideal; $\mathrm{AP}$ stands for the approachability property; $\mathrm {AMTP}(\kappa ^+)$ states that if $2^\kappa <\aleph _{\kappa ^+}$, then every forcing which adds a new subset of $\kappa ^+$ whose initial segments are in the ground model, collapses some cardinal $\leq 2^{\kappa }$. The dotted arrow denotes the relative consistency, while others are logical implications.Appendices. Appendix A includes merely the above diagram. Appendix B presents a proof of the Mapping Reflection Principle with finite conditions under $\mathrm {PFA}$. Appendix C contains open problems. Finally, the thesis’s bibliography consists of 42 items.Abstract prepared by Rahman MohammadpourE-mail: [email protected]: https://theses.hal.science/tel-03209264. (shrink)

One way to compare different theoretical approaches to the study of technologies is to see what the difference is between their narratives of the construction of a particular technology. In this paper, we re-narrate the bicycle construction from the perspective of actor-network theory (ANT), comparing to SCOT’s first account of the construction. Although SCOT has moved closer to actor-network theory later by paying more attention to co-construction and materliaty, Pinch and Biker have not modified their account of the bicycle development (...) according to these theoretical changes, despite the fact that one decade later Bijker allocated one chapter, ‘king of the road’, to Safety bicycle development again. An ANT’s narrative of bicycle development can provide a basis for a concrete comparison between ANT and the classic version of SCOT. Or it could be argued that this narrative could complement the story of Pinch and Biker of bicycle development. While we present a new narrative of bicycle development in comparison with SCOT’s one, we offer a methodological framework in the ANT literature that can be considered as a methodological procedure to the study of artefacts in general; this framework has three elements: 1. Phenomenal Bracketing, 2. Collective construction, and 3. Co-construction. (shrink)

Martin Buber has always made it clear that his dialogic principle is not to be treated as an abstract conception but an ontological reality. But admittedly, in I And Thou he could only point to such reality and could not properly present it in discursive prose. However there are instances in the text where he strives to do the latter. One particular instance is where he elaborates the emergence of consciousness of “I”. Through this elaboration, what Buber has tried to (...) point at is the bringing forth of the primary word ‘I-It’ forming part of his dialogic principle, as it ‘emerges round about’ the perceptual consciousness realised in body as some sort of a ‘primitive function of knowledge’. However, this still amounts only to an abstract conception, and not to a description of ontological reality as Buber would have aspired for. Hence the thought: what if there exists an endeavour carried out independently of Buber’s work, nevertheless in the same spirit as Buber but without his notorious mixing up of philosophy and religion? There indeed has been such an Existential-phenomenological take on embodiment and perception by the French phenomenologist Maurice Merleau-Ponty, as is laid out in his magnum opus Phenomenology of Perception. In the present paper we will explicate this interesting coincidence, thereby honouring Buber’s aspiration for ontological status to his dialogic principle, at the same time demonstrating how existentially resonating and ontologically converging the thought of these two great thinkers’ have been, though they had totally different intellectual pursuits and concerns.

This article explores how the diversity of board resources and the number of women on boards affect firms' corporate social responsibility (CSR) ratings, and how, in turn, CSR influences corporate reputation. In addition, this article examines whether CSR ratings mediate the relationships among board resource diversity, gender composition, and corporate reputation. The OLS regression results using lagged data for independent and control variables were statistically significant for the gender composition hypotheses, but not for the resource diversitybased hypotheses. CSR ratings had (...) a positive impact on reputation and mediated the relationship between the number of women on the board and corporate reputation. (shrink)

Cet article s’attache à définir la nation, en Afrique, par la notion de « révolution », c’est-à-dire d’une transformation totale de conditions anciennes – aussi bien précoloniales que coloniales – en vue de fonder des structures nationales progressistes et démocratiques. Usant de l’exemple des pays du Sahel, en particulier le Burkina Faso, le Mali et le Niger, l’article analyse cette révolution nationale comme un phénomène de cycle long, qui se déploie dans une contradiction entre un leadership politique de moins en (...) moins en adéquation avec elle, et des peuples de plus en plus conscients et exigeants quant à leurs droits civiques. Cette contradiction est par ailleurs déterminée différemment par les problèmes politiques propres au cadre urbain et au cadre rural. Elle aboutit à des luttes et contestations opposant peuples et élites qui indiquent que, si la révolution nationale est loin d’être accomplie, elle n’a pas non plus simplement avorté. (shrink)

Lincoln and Guba provided some principles and four evaluative criteria called “trustworthiness” to guide social science research naturalistically. However, drawing on Science and Technology Studies (STS) literature, a field engaged with methods and practices of science for several decades, one can argue that this approach is not still fully naturalistic. In this paper, we review Lincoln and Guba’s four criteria of trustworthiness from an STS perspective. We argue that the STS literature can challenge these criteria, but at the same time (...) they have the potential to be reconstructed with the help of the materials STS provides. (shrink)

A growing body of work suggests that the presence of women and of independent directors on boards of directors is associated with higher corporate environmental performance. However, the mechanisms linking board composition to corporate environmental performance are not well understood. This study proposes and empirically tests the mediating role of sustainability-themed alliances in the relationship between board composition and corporate environmental performance. Using the population of public oil and gas firms in the United States as the sample, the study relies (...) on renewable energy alliances to measure sustainability-themed alliances and longitudinally analyzes lagged data for independent and control variables. The study found that the higher the representation of women on a firm’s board, the more likely the firm is to form sustainability-themed alliances, and the higher the representation of independent directors on a firm’s board, the more likely the firm is to form sustainability-themed alliances. Such alliances, in turn, positively contribute to corporate environmental performance. This paper discusses the study’s contributions to the board composition-social performance literature. (shrink)

Assuming $\mathrm{PFA}$, we shall use internally club $\omega _1$ -guessing models as side conditions to show that for every tree T of height $\omega _2$ without cofinal branches, there is a proper and $\aleph _2$ -preserving forcing notion with finite conditions which specialises T. Moreover, the forcing has the $\omega _1$ -approximation property.

El objetivo principal de este trabajo es plantear la controversia entre Descartes y Leibniz en torno a las verdades eternas como constituyente de diversos diálogos incluyendo los contralógicos: diálogos en los cuales Descartes y Leibniz representan perspectivas distintas en relación con las elecciones posibles para la determinación de normas de racionalidad. Cada uno de estos diálogos tiene un aspecto universal o monológico (determinado por la estrategia de ganancia), y un aspecto eminentemente contextual y dialógico determinado por el nivel de juego. (...) Finalmente, afirmo que una noción de racionalidad que contenga tanto el aspecto contextual como el universal, no es una lógica específica en forma dialógica sino un cuadro de racionalidad normativa. Lo que, según creo, está relacionado con la idea de la construcción dinámica de una lengua universal perfectible, discutida por Olga Pombo. La idea general es que la noción misma de racionalidad de Leibniz es fondateur de discursivité, si usamos la expresión que Marcelo Dascal toma de la boca de Foucault. The main aim of the present paper is to understand the debate between Descartes and Leibniz about eternal truths as providing the structure of several possible dialogues involving counter-logicals conditionals. According to this analysis the positions of Descartes and Leibniz are understood as constituting dual and dynamic perspectives in relation to the availability of some specific choices that should provide norms of rationality. Each of these dialogues has both a universal, monological aspect (given by the winning strategy) and a contextual, dialogical one (given by the play level). I conclude with the suggestion that a notion of rationality that contains both the universal and the contextual aspects does not yield a specific logic, but rather a frame of normative rationality. The conception of such a frame seems to be closely linked to the notion of a universal perfectible language discussed by Olga Pombo. The central idea is that the Leibniz's notion of rationality is a fondateur de discursivité if we use Marcelo Dascal's quote of Foucault. (shrink)

Marcelo Dascal destaca en diversos artículos en los que analiza las consecuencias de la concepción pragmática del significado, la importancia de estudiar la estructura dialógica de la controversia argumentativa tanto epistemológica como lógica para la formulación de un concepto de conocimiento alternativo al concepto representacional y computacional usual en las ciencias cognitivas. Ahora bien, se supone que la lógica linear es el instrumento más apropiado para describir procesos computacionales de deducción. Irónicamente, las semánticas formales usuales, que podrían utilizarse para una (...) fundamentación representacional de la lógica linear han sido hasta ahora más bien infructuosas. Es más, parece que la semántica de la lógica linear es esencialmente pragmática y basada en una estructura dialógica. Objetivo de este trabajo es discutir una nueva semántica para la lógica linear que destaca precisamente los fundamentos pragmáticos de tales aspectos dialógicos entendidos como una controversia argumentativa, a saber, contexto de argumentación, relevancia e intercambio de información.

Ojectives Low energy hip fractures are one of the greatest causes of morbidity and mortality in orthopaedics. This study aims to evaluate written consent forms with respect to basic standards as set out in the Good Practice in Consent Initiative. In particular the stated risks and benefits of each procedure were assessed. Methods 100 consecutive consent forms were reviewed prospectively. The stated procedure, side and complications were recorded. Appropriate signature and legibility was assessed. 13 consultant orthopaedic surgeons were surveyed to (...) identify what risks and benefits they thought should be stated. Results Of 100 consent forms, 31 were for patients who are unable to consent. All 100 consent forms were correctly filled in with patient details and signed. 98% were legible. All stated the side of the operation. The number of complications listed per form ranged from 4 to 11. Infection, bleeding and thromboembolic complications were stated in the majority of consent forms. In total, 30 different complications were recorded; some were only stated once. Discussion and Conclusions This work suggests consent forms are completed well with respect to patient identifiers, legibility and procedure. The variability of complications stated is vast. We suggest standard pre-printed consent forms containing risks and benefits should be used as this may improve standards of informed consent. This has also been recently supported by the British Orthopaedic Association. (shrink)

What are the political implications of a complex image of time, where time does not unfold progressively in a neat linear structure, but where the past is always present and the future impinges on the now? If the past is inescapably present, how do societies that live with grievously injured pasts come to terms with them in the present for the sake of the future? How do they try to address the collective memories of their people, when such memories are (...) marked by violence and conflict, without resorting to vengeance? Drawing from the philosophical writings of Friedrich Nietzsche, this article examines the way in which two countries have recently attempted to negotiate the politics of memory – Algeria and Rwanda. It poses such questions as how much should be forgotten and how much should be remembered? It also asks the difficult question of how such pasts can be overcome and transfigured in the present for the sake of the politics of an affirmative politics of the future. (shrink)

Wealth distribution based on classic sugarscape model leads to a population increase and the Gini coefficient decrease when cooperation and communication parameters are taken into account. In another study, this model was developed by implying a receipt of one-fifth of the assets of the population and derived utilization for poor people. The results showed a relation between mortality decrease, population increase, and Gini coefficient decrease (equality increase). In a synergic process, the wealth adjustment based on sugarscape model underwent some experiments (...) by implying communication and cooperation, and the mechanism of receiving and utilizing the assets.

Purpose This study aims to analyze how English-language versions of e-newspapers in the first two countries affected, China and Japan, which are non-English-speaking countries and have different socio-economic and political settings, have highlighted Coronavirus disease 2019 pandemic news and informed the global community. Design/methodology/approach A text-mining approach was used to explore experts’ thoughts as published by the two leading English-language newspapers in China and Japan from January to March 2020. This study analyzes the Opinion section, which mainly comprises editorial and (...) the op-ed section. The current study groups all editorial discussions and highlights into ten major aspects, which cover health, economy, politics, culture and others. Findings Within the first three months, the media in both China and Japan shifted their focus from health and preparedness to the economy, politics and social welfare. Governance and social welfare were key concerns in China’s news media, while, in contrast, global politics received the highest level of attention from experts in Japan’s news media. Environment and technologies aspects did not receive much attention by the expert’s columns. Originality/value At the initial stage of a world crisis, how leading nations and initially affected nations deal with the problem, how media play their role and guide mass population with experts’ thoughts are highlighted here. The understanding developed in this study can provide guidance to news media in other countries in playing effective roles in the management of this health crisis and catastrophes. (shrink)
