There is growing interest for implementing tools to monitor cognitive performance in naturalistic work and everyday life settings. The emerging field of research, known as neuroergonomics, promotes the use of wearable and portable brain monitoring sensors such as functional near infrared spectroscopy (fNIRS) to investigate cortical activity in a variety of human tasks out of the laboratory. The objective of this study was to implement an on-line passive fNIRS-based brain computer interface to discriminate two levels of working memory load during (...) highly ecological aircraft piloting tasks. Twenty eight recruited pilots were equally split into two groups (flight simulator vs. real aircraft). In both cases, identical approaches and experimental stimuli were used (serial memorization task, consisting in repeating series of pre-recorded air traffic control instructions, easy vs. hard). The results show pilots in the real flight condition committed more errors and had higher anterior prefrontal cortex activation than pilots in the simulator, when completing cognitively demanding tasks. Nevertheless, evaluation of single trial working memory load classification showed high accuracy (>76%) across both experimental conditions. The contributions here are two-fold. First, we demonstrate the feasibility of passively monitoring cognitive load in a realistic and complex situation (live piloting of an aircraft). In addition, the differences in performance and brain activity between the two experimental conditions underscore the need for ecologically-valid investigations. (shrink)

When its atmosphere processing plant's fusion reactor exploded, it turned it into a desolate, irradiated hunk of rock uninhabitable by humans for thousands of years. The explosion was not far off from what the surviving humans in Aliens were planning anyway: nuke the site from orbit. To set the stage for considering the military decisions of Colonial Marines from an ethical perspective, strap in like it's a simulated combat drop from low orbit. This chapter looks at the Aliens future of (...) the twenty‐second century. After the first tragic encounter with the Xenos in Aliens, the remaining humans are trying to figure out their next steps in the back of the armored personnel carrier (APC). Many of the ideas being tossed around in the APC (even slimy Carter Burke's) keep the Xenos distant and so actually reduce the threat, backing the humans away from the need to make decisions in a “supreme emergency”.

Suivant le fil directeur du temps, cet ouvrage met au jour la manière dont l'admiration est devenue un problème philosophique central à l'âge classique et examine les différentes conceptions dont elle fait l'objet chez les principaux penseurs de la seconde moitié du XVIIe siècle.

After spinal cord injury (SCI), motoneuron death occurs at and around the level of injury which induces changes in function and organization throughout the nervous system, including cortical changes. Muscle affected by SCI may consist of both innervated (accessible to voluntary drive) and denervated (inaccessible to voluntary drive) muscle fibers. Voluntary activation measured with transcranial magnetic stimulation (VATMS) can quantify voluntary cortical/subcortical drive to muscle but is limited by technical challenges including suboptimal stimulation of target muscle relative to its antagonist. (...) The motor evoked potential (MEP) in the biceps compared to the triceps (i.e., MEP ratio) may be a key parameter in the measurement of biceps VATMS after SCI. We used paired pulse TMS, which can inhibit or facilitate MEPs, to determine whether the MEP ratio affects VATMS in individuals with tetraplegia. Ten individuals with tetraplegia following cervical SCI and ten non-impaired individuals completed single pulse and paired pulse VATMS protocols. Paired pulse stimulation was delivered at 1.5, 10, and 30 ms inter-stimulus intervals (ISI). In both the SCI and non-impaired groups, the main effect of the stimulation pulse (paired pulse compared to single pulse) on VATMS was not significant in the linear mixed-effects models. In both groups for the stimulation parameters we tested, the MEP ratio was not modulated across all effort levels and did not affect VATMS. Linearity of the voluntary moment and superimposed twitch moment relation was lower in SCI participants compared to non-impaired. Poor linearity in the SCI group limits interpretation of VATMS. Future work is needed to address methodological issues that limit clinical application of VATMS. (shrink)

Cet article examine la question de l’attention dans son rapport à l’admiration, dont le traitement fait apparaître de profondes divergences entre les Passions de l’âme et l’ Éthique. Dans Les Passions de l’âme, Descartes propose une genèse passionnelle de l’attention, dont la destination gnoséologique est assurée par un acte de la volonté qui transcende les perceptions de l’âme. À l’inverse, dans l’ Éthique, la connaissance ne dépend pas de l’exercice d’une faculté autonome, elle est immanente à l’ordre des idées, ce (...) à quoi l’admiration fait irréductiblement obstacle. La critique spinoziste de l’admiration s’accompagne alors d’une refonte du statut de l’attention et repose sur la critique de la partition cartésienne des facultés de l’âme. Nous montrerons néanmoins que l’attention a une fonction positive sous la forme d’une présence à soi de l’esprit qui veille à l’enchaînement en lui des idées vraies. (shrink)

In this classic analysis, Leo Strauss pinpoints what is original and innovative in the political philosophy of Thomas Hobbes.

Recent feminist philosophy of language has highlighted the ways that the speech of women can be unjustly impeded, because of the way their gender affects the uptake their speech receives. In this chapter, I explore how similar processes can undermine the speech of a different sort of speaker: Indigenous communities. This involves focusing on Indigeneity rather than gender as the salient social identity, and looking at the ways that group speech, rather than only individual speech, can be unjustly impeded. To (...) do this, I make use of the notion of ‘discursive injustice’ that has been developed by Quill Kukla, and, with reference to three case studies, show how discursive injustice can effectively derail the speech of Indigenous communities.

In this paper, we present a critical reflection on the concept of social capital. We argue that there is no such idea of an umbrella concept of social capital. Instead, two overarching conceptualizations of social capital exist, namely individual social capital and collective social capital. As these conceptualizations of social capital are completely different, we emphasize that studies using social capital as a theoretical lens should clarify the concept as well as be consistent in the interpretation of the concept, from (...) its definition to its methodological operationalization. In this article, we first map the two different conceptualizations of social capital. Next, these conceptualizations are illustrated with well-known teacher research studies, followed by examples of studies in which individual and collective social capital are mixed. Finally, we discuss the consequences of the use and the mix of these different conceptualizations in terms of measurement methods. Additionally, implications for teacher education are presented.

The concepts underlying our present theoretical understanding of the radiative two-condensed-body problem in general relativity and in bimetric gravitation theory are critically reviewed. The relevance of the 1935 Einstein-Rosen “bridge” article is emphasized. The possibility (first suggested by N. Rosen, for the linearized approximation) of extending to gravity the Wheeler-Feynman time-symmetric approach is questioned.

L’un des gestes distinctifs de Cornelius Castoriadis fut de rapporter l’histoire de la philosophie à un concept de création « ex nihilo », qu’il définissait comme surgissement immotivé et irréductible de nouvelles déterminations formelles de l’être dans le temps. Cet article s’intéresse à la signification d’un tel parti pris pour l’instruction de la question cosmologique, entendue comme enquête sur les principes et le devenir de la totalité de l’être. L’auteur montre dans un premier temps comment Castoriadis a justifié sa position (...) ontologique à partir d’une réflexion sur l’histoire de la science. Il la rapporte ensuite à deux voies possibles afin de résoudre la question cosmologique : la dialectique et la complexité. Il est soutenu que l’intention de Castoriadis ne fut pas de produire une cosmologie comme telle, mais de rapporter la pratique scientifique à la création et d’expliciter les conditions de possibilité de son intellection.

Jean-Marc Ferry stands opposed to the philosophy of Cornelius Castoriadis, claiming that it relies upon an arbitrary ontological decision. According to Ferry, Castoriadis’ philosophy does not respect the Kantian critique of reason. In this contribution, I reply to this objection. I comment on his specific methodological operation: elucidation. I show that this method does not go beyond Kantian finitude, and that it allows him to justify his ontological concepts. In the last part of this article, I interpret his method as (...) a ‘grounded constructivism’ and I explain how it contributes to those philosophical theories. (shrink)

Dans les théories esthétiques de la fin du XIXe siècle, l’exemple de l’architecture appuie une inversion progressive des hiérarchies entre le beau et l’utile, confortée par la montée des approches sociologiques et anthropologiques de l’art. Du côté des architectes, les débats sur l’origine et l’évolution des styles, depuis leurs manifestations primitives dans les industries d’art vers les formes plus évoluées de l’art monumental, infléchissent la compréhension des relations entre détermination matérielle et expression artistique.

Through a detailed re-reading of Saussure's work in the light of contemporary developments in the human, life and physical sciences, Paul Thibault provides us with the means to redefine and refocus our theories of social meaning-making. Saussure's theory of language is generally considered to be a formal theory of abstract sign-types and sign-systems, separate from our individual and social practices of making meaning. In this challenging book, Thibault presents a different view of Saussure. Paying close attention to the (...) original texts, including the Cours de Linguistic Generale, he demonstrates that Saussure was centrally concerned with trying to formulate a theory of how meanings are made. In addition to demonstrating the continuing viability of Saussure's thinking through a range of examples, Re-reading Saussure makes an important intervention in contemporary linguistic and semiotic debate.

The far reaching changes in man's social and personal life taking place in our lifetime underline the need for a sound ethical evaluation of our rights and duties and of human behaviour both on the individual level and in the political society. On many issues judgments of value vary widely and a consultation of the thought of Thomas Aquinas on the basic questions will be helpful, the more since he is not only one of the greatest philosophers but also succeeded (...) in integrating in his moral philosophy the wisdom of the ancients, in particular of Aristotle and the Stoa. This book presents Aquinas's thought on such central questions as man's happiness, how to determine the morality of our actions, the natural law and the main virtues, as well as on the common good, war, human labour, love and friendship. Throughout the book the intellectual character of this moral philosophy is pointed out and problems are set in a historical perspective. (shrink)

Dans l'oeuvre d'Edith Stein, l'alterite apparait comme constitutive de la personne humaine. D'un point de vue proprement subjectif, l'alterite renvoie... l'alter ego,... la dimension communautaire et, dans une perspective croyante, au Tout-Autre. D'un point de vue objectif, elle designe les valeurs, qui faconnent la personnalite, et la foi, qui vient au secours de la raison humaine. Un parcours des oeuvres principales de l'auteur permet de prendre la mesure... la fois de la continuite et de l'evolution de sa pensee. A partir (...) de l..., l'etude entreprend de mettre en evidence, d'une part, l'originalite de la pensee d'Edith Stein par rapport... celle de Husserl et, d'autre part, comment Edith Stein se situe par rapport... la pensee de Thomas d'Aquin. L'influence de l'oeuvre de Jean de la Croix est egalement abordee. Enfin, en dialogue avec des auteurs comme Ricoeur, Levinas ou Ladriere, la troisieme partie du livre aborde de maniere critique la question de l'alterite comme fondement de la personne et cela selon trois parcours, l'un lie... la phenomenologie d'Edith Stein, l'autre... sa philosophie chretienne, et le dernier... son attrait pour la mystique.

There is widespread and growing concern among U.S. consumers about the treatment of farmed animals, and consumers are consequently paying attention to food product labels that indicate humane production practices. However, labels vary in their standards for animal welfare, and prior research suggests that consumers are confused by welfare-related labels: many shoppers cannot differentiate between labels that indicate changes in the way animals are raised and those that do not. We administered a survey to 1,000 American grocery shoppers to better (...) understand the extent to which consumers purchase and pay more for food with certain labels based on an assumption of welfare improvement. Results showed that 86% of shoppers reported purchasing at least one product with the following labels in the last year: “cage or crate-free”, “free-range”, “pasture-raised”, “natural”, “organic”, “no hormone”, “no antibiotic”, “no rBST”, “humane”, “vegetarian-fed”, “grass-fed”, “farm-raised”. Of those who purchased one of the aforementioned labels, 89% did so because they thought the label indicated higher-welfare production practices, and 79% consciously paid more for the product with the label because they thought that the label indicated better-than-standard animal welfare. However, many of these labels lack uniform standards for the production practices they represent, and some labels represent production practices that do not influence animal welfare, thus the degree of the animal welfare impact of a given label is highly variable. These results indicate that labels need to clearly and accurately specify their animal welfare benefits to improve the consumers’ ability to purchase products that align with their expectations.

Michael Gilbert’s multi-modal theory of argument challenges earlier accounts of arguing assumed in formal and informal logic. His account of emotional, visceral, and kisceral modes of arguing rejects the assumption that all arguments must be treated as instances of one “logical mode.” This paper compares his alternative modes to other modes proposed by those who have argued for visual, auditory, and other “multimodal” modes of arguing. I conclude that multi-modal and multimodal (without the hyphen) modes are complementary. Collectively, they represent (...) an important attempt to radically expand the scope of informal logic and the argumentation that it studies. (shrink)
