BackgroundAlthough gait patterns disturbances are known to be related to cognitive decline, there is no consensus on the possibility of predicting one from the other. It is necessary to find the optimal gait features, experimental protocols, and computational algorithms to achieve this purpose.PurposesTo assess the efficacy of the Stable Sparse Classifiers procedure for discriminating young and healthy older adults, as well as healthy and cognitively impaired elderly groups from their gait patterns. To identify the walking tasks or combinations of tasks (...) and specific spatio-temporal gait features that allow the best prediction with SSC.MethodsA sample of 125 participants was studied. They underwent assessment with five neuropsychological tests that explore different cognitive domains. A summarized cognitive index, based on the Mahalanobis distance from normative data, was calculated. The sample was divided into three groups using k-means clustering of MDCog in addition to Age. The participants executed four walking tasks and their gait patterns, measured with a body-fixed Inertial Measurement Unit, were used to calculate 16 STGF and dual-task costs. SSC was then employed to predict which group the participants belonged to. The classification's performance was assessed using the area under the receiver operating curves and the stable biomarkers were identified.ResultsThe discrimination HE vs. MCI-E revealed that the combination of the easy dual-task and the fast walking task had the best prediction performance. The features related to gait variability and to the amplitude of vertical acceleration had the largest predictive power. SSC prediction accuracy was better than the accuracies obtained with linear discriminant analysis and support vector machine classifiers.ConclusionsThe study corroborated that the changes in gait patterns can be used to discriminate between young and healthy older adults and more importantly between healthy and cognitively impaired adults. A subset of gait tasks and STGF optimal for achieving this goal with SSC were identified, with the latter method superior to other classification techniques. (shrink)

Ernest Sosa has proposed two different ways to respond to dreaming skepticism. In this paper I argue that Sosa's first response —which centers on holding that we have no beliefs in dreams— does not appear to be successful against either the hyperbolic or the realistic dreaming skeptic. I also argue that his second attempt to respond to the dreaming skeptic by arguing that perceptual knowledge indeed counts as what he calls "animal knowledge", may succeed but requires us to (...) perform what appears to be some radical surgery on the concept of knowledge; a radical surgery that, as I show, is probably unnecessary to avoid dreaming skepticism. Finally, I sketch some independent considerations why I think that the hyperbolic skeptic's dreaming argument is not acceptable. Ernesto Sosa propone dos maneras de responder al escéptico del sueño. En este ensayo argumento que su primera propuesta, según la cual no tenemos creencias en los sueños, no parece ser una buena respuesta en contra de ninguno de los escepticismos del sueño, de los cuales distingo dos tipos: el hiperbólico y el realista. También argumento que su segunda propuesta para responder al escéptico del sueño, en la que argumenta que el conocimiento perceptual sí cuenta como conocimiento animal, quizá resulte exitosa; sin embargo, ésta requiere llevar a cabo una cirugía radical en el concepto de conocimiento; una cirugía que, como muestro, es probablemente innecesaria para evitar el escepticismo del sueño. Finalmente bosquejo algunas razones independientes por las cuales considero que el argumento del escéptico hiperbólico del sueño no es aceptable. (shrink)

Castañeda, Perry and Lewis argued in the 1960’s and 1970’s that thoughts about oneself “as oneself” – de se thoughts – require special treatment, and advanced different accounts. In this paper I discuss Ernest Sosa’s approach to these matters. I first present his approach to singular or de re thought in general in the first section. In the second, I introduce the data that need to be explained, Perry’s and Lewis’s proposals, and Sosa’s own account, in relation to (...) Perry’s, Lewis’s, and his own views on de re thought. In the third section I present the account I prefer – a “token-reflexive” version of Perry’s original account that Perry himself came to adopt in reaction to Stalnaker’s criticisms. In the final section I take up Recanati’s recent arguments, from a viewpoint on de se thought very similar to Sosa’s, to the effect that such an account is in a good position to explain the phenomenon of immunity to error through misidentification. I argue there that that is not the case, and I conclude by suggesting that the token-reflexive account fits better both with the data and with Sosa’s Fregean take on de re thought in general.

This paper argues that the weaker elements in the anti-sceptical strategy deployed by Sosa in "A Virtue Epistemology" can be improved, within the general framework provided by virtue epistemology, if internalism about perceptual experience is abandoned.

Questions Sosa's views on Fregean referece.

I defend a Deferred Ostension view of quotation, on which quotation-marks are the linguistic bearers of reference, functioning like a demonstrative; the quoted material merely plays the role of a demonstratum. On this view, the quoted material works like Nunberg’s indexes in his account of deferred ostensión in general. The referent is obtained through some contextually suggested relation; in the default case the relation will be … instantiates the linguistic type __, but there are other possibilities. In this way, the (...) deferred ostension view deals with a problem I pointed out for the identity proposal in my earlier work, that we do not merely refer with quotations to expression-types, but also to other entities related in some way to the relevant token we use: features exhibited by the token distinct from those constituting its linguistic type, features exhibited by other tokens of the same type but not by the one actually used (as when, by using a graphic token, we refer to its phonetic type), or even other related tokens (see the examples on p. 261 of García-Carpintero 1994).

Rational beings pursue and value truth . Intellectual conduct is to be judged, accordingly, by how well it aids our pursuit of that ideal. I ask whether these platitudes mean, and whether they are true.

This paper proposes an epistemological approach to analyse social-ecological systems from a process perspective in order to better tackle the co-constitution of the social and the ecological and the dynamism of these systems. It highlights the usefulness of rethinking our conceptual tools taking processes and relations as the main constituents of reality instead of fundamental substances or essences. We introduce the concept of experience as understood in radical empiricism to critically revise our available concepts through focusing on the concept of (...) difference, exploring apparent contradictions and engaging in assemblage thinking.

Social network sites are a new communication channel to convey CSR information. They are interactive channels that let users participate, spread content and generate positive and negative electronic word-of-mouth about companies that can dramatically affect their reputation and future business. To identify the factors behind this behaviour, we designed a causal model to explain the intention to both comment on and share a negative corporate social responsibility news posted on Facebook. We included the following as explanatory variables: social consciousness, environmental (...) consciousness, information usefulness, corporate image and attitude towards sharing and commenting on CSR news. We surveyed 208 Facebook users who evaluated a fictitious news item about an environmental issue. We observed that social and environmental consciousness influences the usefulness of information and the attitude towards behaviour, which may explain the eWOM intention of the specific news. However, corporate image can cause people to refrain from generating eWOM and spreading the news on their friend social network. (shrink)

This volume represents the most comprehensive and authoritative collection of canonical readings in theory of knowledge. It is ideal as a reader for all courses in epistemology.

That conception is orthodox in today’s common sense and also historically. Presupposed by Plato, Augustine, and Descartes, it underlies familiar skeptical paradoxes. Similar orthodoxy is also found in our developing science of sleep and dreaming.[2] Despite such confluence.

The knowledge account of assertion—roughly: one should not assert what one does not know—aspires to identify the norm distinctive of assertion. One main argument given in support of the knowledge account has been the success with which it explains a variety of Moore-paradoxical assertion. But that explanation does not generalize satisfactorily.

ABSTRACTPrior research has found a relationship between perceived facial attractiveness and perceived personal trustworthiness. We examined the time course of attractiveness relative to trustworthiness evaluation of emotional and neutral faces. This served to explore whether attractiveness might be used as an easily accessible cue and a quick shortcut for judging trustworthiness. Detection thresholds and judgment latencies as a function of expressive intensity were measured. Significant correlations between attractiveness and trustworthiness consistently held for six emotional expressions at four intensities, and neutral (...) faces. Importantly, perceived attractiveness preceded perceived trustworthiness, with lower detection thresholds and shorter decision latencies. This reveals a time course advantage for attractiveness, and suggests that earlier attractiveness impressions could bias trustworthiness inferences. A heuristic cognitive mechanism is hypothesised to ease processing demands by relying on simple a... (shrink)

RESUMENEn este artículo vamos a tratar la complejidad de la noción de cultura. La cultura ha sido tratada por muchos movimientos y por muchos pensadores. Nos centraremos en algunos de ellos y sobre todo en García Morente. La cultura es el ámbito en que se mueve todo y de modo especial el lenguaje; el marco ineludible y el mayor reto de la traducción.PALABRAS CLAVECULTURA – CIVILIZACION – TRADUCCION ABSTRACTThe complex notion of culture is the main subject of this article. (...) It has been studied by many movements and scholars, notably by García Morente, whose thesis on culture will be discussed. Everything, as well as language, in its own special way, comes under the scope of culture. Thus culture bound lexical items and concepts being the greatest challenge for the translator.KEYWORDSCULTURE – CIVILIZATION - TRANSLATION. (shrink)

This paper takes up the critique of armchair philosophy drawn by some experimental philosophers from survey results. It also takes up a more recent development with increased methodological sophistication. The argument based on disagreement among respondents suggests a much more serious problem for armchair philosophy and puts in question the standing of our would-be discipline.

In lieu of an abstract, here is a brief excerpt of the content:Diacritics 30.4 (2000) 102-122 [Access article in PDF] How To Tell a Mestizo from an Enchirito® Colonialism and National Culture in the Borderlands Michael Hames-garcia I began to think, "Yes, I'm a chicana but that's not all I am. Yes, I'm a woman but that's not all I am. Yes, I'm a dyke but that doesn't define all of me. Yes, I come from working class origins, but I'm (...) no longer working class. Yes, I come from a mestizaje, but which parts of that mestizaje get privileged? Only the Spanish, not the Indian or black." I started to think in terms of mestiza consciousness. What happens to people like me who are in between all of these different categories? What does that do to one's concept of nationalism, of race, ethnicity, and even gender? I was trying to articulate and create a theory of a Borderlands existence.... I had to, for myself, figure out some other term that would describe a more porous nationalism, opened up to other categories of identity. —Gloria E. Anzaldúa, InterviewsOne of the most crucial questions facing leftist activists and intellectuals today is the question of nationalism and its relation to liberation struggles. 1 A century ago, the period [End Page 102] of nation-state consolidation in Europe seemed to come to an end with the unification of Germany and Italy. European leftists of the era tended to address "the national question" primarily with regard to those European nations that were shut out or suppressed by nation-state formation. Debates about national culture resurfaced in a revolutionary context when independence movements swept Africa and Asia during and after World War II, and a substantial body of literature attempting to integrate anticolonial struggle, national liberation, and socialism arose from the capitalist "periphery." Much of this literature, and the wars for independence out of which it grew, adapted the language of nationalism to its own purposes. These movements gave new hope that national liberation struggles would prove compatible with greater human freedom and equality. Despite that hope, the destructive effects of nationalism are today visible everywhere: for example, the devastating wars in the Balkans, the repression of indigenous peoples by national bourgeoisie throughout the Americas, religious-national strife between Sinhalese and Tamils in Sri Lanka, the vertiginous intensification of national chauvinism in the United States, Western Europe, and Australia. Simultaneously, and in the context of feminist criticisms of nationalism [see, for example, Chatterjee, Nation; Lutz et al.; Mosse], attempts to unite the struggle to liberate "the nation" from colonial or neocolonial domination with progressive struggles against capitalist exploitation and against sexual- and gender-based domination continue [see, for example, Trask]. In Latin America, anticapitalist struggles lauded by Western socialists regularly take the form of national liberation struggles, such as the EZLN (Ejército Zapatista de Liberación Nacional [Zapatist National Liberation Army]) in Mexico and the FSLN (Frente Sandinista de Liberación Nacional [Sandinist National Liberation Front]) in Nicaragua. Additionally, lesbian and gay activists and theorists in the United States have frequently sought to appropriate nationalist rhetoric even as black and Chicano nationalist movements have been on the decline [see, for example, Berlant and Freeman; Moraga 145-74].Debates about anticolonial struggle and "Third World" nationalism may seem at first to be an odd context into which to introduce the work of Gloria Anzaldúa. Critical writing on Anzaldúa's work has tended not to consider its relevance to debates on the relations among capitalism, colonialism, and national culture. 2 Instead, her major work, Borderlands/La Frontera, is usually discussed (or, more often than not, simply cited) as a contribution to feminist and antiracist discussions about the construction of the self within multiple contexts of domination and about that self's resistance to oppression and struggle for recognition. 3 While acknowledging the importance of Anzaldúa's contributions to these discussions, this essay examines Borderlands as offering a forward-looking alternative to nationalism, specifically, to Chicano cultural nationalist positions articulated during the...

The introduction of a new analytical method, due fundamentally to François Viète and René Descartes and the later dissemination of their works, resulted in a profound change in the way of thinking and doing mathematics. This change, known as process of algebrization, occurred during the seventeenth and early eighteenth centuries and led to a great transformation in mathematics. Among many other consequences, this process gave rise to the treatment of the results in the classic treatises with the new analytical method, (...) which allowed new visions of such treatises and the obtaining of new results. Among those treatises is the Arithmetic of Diophantus of Alexandria which was written, using the new algebraic language, by the French mathematician Jacques Ozanam, who in addition to profusely increasing the original problems of Diophantus, solved them in a general way, thus obtaining many geometric consequences. The work is handwritten, it has never been published, it has been lost for almost 300 years, and the known references show its importance. We will show that Ozanam’s manuscript was quoted as an important work on several occasions by others mathematicians of the time, among whom G. W. Leibniz stands out. Once the manuscript has been located, our aim in this article is to show and analyze this work of Ozanam, its content, its notation and its structure and how, through the new algebraic method, he not only solved and expanded the questions proposed by Diophantus, but also introduced a connection between the algebraic solutions and what he called geometric determinations by obtaining loci from the solutions.

This essay concerns the causation involved in divine sustenance—the “pressure of the will of God” that continually upholds things in existence and supplies them with their properties and powers. My aim is to consolidate the theological doctrine of sustenance and a metaphysical theory of properties. Towards that end, I develop and motivate two consolidatory proposals, which together secure a more parsimonious theistic ontology and integrate the doctrine of sustenance and a theory of properties in a mutually enhancing way. The bulk (...) of the essay concerns the first proposal, which I explain and motivate in the first three sections. In the last two sections I explain and motivate the second proposal. (shrink)

Drawing on Brown and Fraser’s (in: Giles, Scherer (eds) Social markers in speech, Cambridge University Press, Cambridge, pp 33–62, 1979) framework for the analysis of communicative situations and Fuentes Rodríguez’s (Lingüística pragmática y Análisis del discurso, Arco Libros, Madrid, 2000; in Estudios de Lingüística: Investigaciones lingüísticas en el siglo XXI, 2009. https://doi.org/10.14198/ELUA2009.Anexo3.04 ) model of pragmatic analysis, this paper examines three home-made recordings featuring some of the members of the terrorist cell responsible for the 2017 vehicle-ramming attacks in Barcelona and (...) Cambrils weighted as evidence during the trial held between November 2020 and May 2021 in the Spanish National High Court. The aim of this qualitative analysis is to test whether the linguistic evidence available supports the allegation that the participation in these recordings by one of the accused, Mohamed Houli Chemlal, had been planned by his interlocutors. Results show, first, that the exchanges analyzed present features indicative of both spontaneity and (limited) planification. Second, that Houli makes key contributions to the unfolding of the interactions shown in the recordings and that he does so in a cooperative and apparently relaxed manner, which could at best provide only partial support to his allegations. It is claimed that forensic linguistic analysis can generate valuable insights within terrorism-related legal proceedings. (shrink)

Having fascinated some of the greatest philosophers from the earliest times, dreaming figures importantly in the history of philosophy, as in Plato’s Theaetetus, Augustine’s Confessions, and, perhaps most famously, Descartes’s Mediations. By far the greatest philosophical focus on dreaming has been epistemic: Socrates suggests to Theaetetus that since he cannot tell whether he is dreaming, he cannot trust his senses to know contingent facts about the world around him. And a similar worry drives Descartes’s radical doubt in the First Meditation. (...) We might think that dream skepticism is, among the radical Cartesian skeptical scenarios, a particularly worrying one, since dreams, unlike evil demons, are a commonplace of everyday life. (shrink)

El presente artículo sostiene la siguiente hipótesis: la inmensa mayoría de las conceptualizaciones teóricas con las que, a inicios del siglo XXI, se intenta dar cuenta de la subjetividad contemporánea son explícita o subrepticiamente reelaboraciones del concepto de superhombre. De ciborgs a posthumanos, pasando por una amplia y variada gama de sujetos contemporáneos, se puede apreciar que el concepto de Übermensch aporta las claves fundamentales con las cuales deconstruir el concepto de identidad fija que pone en juego el universalismo abstracto. (...) Siguiendo la teorización de Nietzsche, estas nuevas posiciones teóricas proponen una forma particular y concreta de vida como alternativa a las dicotomías y trasmundos con que la metafísica construyó a los sujetos del pasado. Sin embargo, estas propuestas han pasado por alto algo fundamental. Para demostrarlo, proponemos una relectura de Nietzsche y de dichos conceptos con el objetivo de plantear una nueva manera de pensar sobre la vida. (shrink)

Dating manuscripts is a difficult task – particularly when these are not expressly datemarked, but even when they are. Factors such as the existence of successive copies that continue and repeat established models and production methods make dating a challenging task.

By means of a study protocol, errors in the dating of (...) manuscripts ms6, ms10, ms26 and ms29 are successfully detected and corrected, and alternative dating proposed. (shrink)

The aims of the study were to identify coach profiles and examine whether participants from distinct profiles significantly differed on burnout, emotions and coping. A sample of 268 athletes (Mage = 29.34; SD = 12.37), completed a series of self-reported questionnaires. Cluster analyses revealed two coach leadership profiles: (a) profile 1 with high scores of training and instruction, authoritarian behavior, social support and positive feedback, and a low score of democratic behavior; and (b) profile 2 with low levels in training (...) and instruction, authoritarian behavior, social support and positive feedback and high levels in democratic behavior. Results of MANOVAs indicated significant differences across coach profiles on reduced accomplishment, sport devaluation, happiness and seeking support and marginal differences on dejection, logical analysis, imagery/thought control, and excitement. Moreover, coach leadership profiles were not confounded by demographic variables (level of competition, gender, age, number of practice hours, professional versus no professional athletes). As a conclusion, the profile approach offered a holistic way to examine coach leadership in sport as two distinct coach profiles emerged from the cluster analyses with an unexpected combination of coach leadership dimensions.
