Aim: The present work proposes the study of the neuromotor activity of the masseter-jaw-tongue articulation during diadochokinetic exercising to establish functional statistical relationships between surface Electromyography, 3D Accelerometry, and acoustic features extracted from the speech signal, with the aim of characterizing Hypokinetic Dysarthria. A database of multi-trait signals of recordings from an age-matched control and PD participants are used in the experimental study. Hypothesis: The main assumption is that information between sEMG and 3D acceleration, and acoustic features may be quantified (...) using linear regression methods. Methods: Recordings from a cohort of eight age-matched control participants and eight PD participants were collected during the utterance of a diadochokinetic exercise. The dynamic and acoustic absolute kinematic velocities produced during the exercises were estimated by acoustic filter inversion and numerical integration and differentiation of the speech signal. The amplitude distributions of the absolute kinematic and acoustic velocities are estimated to allow comparisons in terms of Mutual Information. Results: The regression results show the relationships between sEMG and dynamic and acoustic estimates. The projection methodology may help in understanding the basic neuromotor muscle activity regarding neurodegenerative speech in remote monitoring neuromotor and neurocognitive diseases using speech as the vehicular tool, and in the study of other speech-related disorders. The study also showed strong and significant cross-correlations between articulation kinematics, both for the control and the PD cohorts. The absolute kinematic variables presents an observable difference for the PD participants compared to the control group. Conclusion: Kinematic distributions derived from acoustic analysis may be useful biomarkers toward characterizing HD in neuromotor disorders providing new insights into PD. (shrink)

Marr’s celebrated contribution to cognitive science (Marr 1982, chap. 1) was the introduction of (at least) three levels of description/explanation. However, most contemporary research has relegated the distinction between levels to a rather dispensable remark. Ignoring such an important contribution comes at a price, or so we shall argue. In the present paper, first we review Marr’s main points and motivations regarding levels of explanation. Second, we examine two cases in which the distinction between levels has been neglected when considering (...) the structure of mental representations: Cummins et al.’s distinction between structural representation and encodings (Cummins in Journal of Philosophy, 93(12):591–614, 1996; Cummins et al. in Journal of Philosophical Research, 30:405–408, 2001) and Fodor’s account of iconic representation (Fodor 2008). These two cases illustrate the kind of problems in which researchers can find themselves if they overlook distinctions between levels and how easily these problems can be solved when levels are carefully examined. The analysis of these cases allows us to conclude that researchers in the cognitive sciences are well advised to avoid risks of confusion by respecting Marr’s old lesson. (shrink)

Suppose you utter the sentence “I am a professional philosopher”. Can I –or anybody else – literally express the same thought you thereby expressed? An affirmative answer implies a potential split between the referent of the thought you expressed and its thinker, as well as the possibility of expressing that thought without using the first person pronoun. Here I attempt to clarify the basic features of a reference rule individuating such an intersubjectively shareable type of thought, i.e. the self type. (...) Doing so requires meeting Bermúdez’s (2019) challenge, namely, the challenge of determining (a) in virtue of what is an individual the referent but not necessarily the thinker of the thought in such cases, and (b) what makes it the case that a sentence is used to express a self type of thought, as opposed to a thought of another type. I advance an elucidation that is entirely congenial to Bermúdez’s own account in terms of location abilities. Contrary to what he suggests, however, the analysis plausibly remains one at the level of the contextually constrained type (or instantiable type), and leads to a revision – if not a straightforward rejection – of Frege’s Criterion for the individuation of thought.

Abstract.The United States today is faced with a crisis of the liberal system stemming from a shortage of resources and ideas. Liberalism assumes that there will always be enough resources to meet all needs and that politics consists of the struggle of interest groups for resources to meet their particular needs. Liberalism is wrong on both counts: there are not enough resources and there is a common good which includes all particular needs properly understood. We must now revise our ideas (...) and institutions in order to make the common good attainable. Various changes in ideas and institutions toward that end are suggested. (shrink)

_On Tyranny_ is Leo Strauss’s classic reading of Xenophon’s dialogue _Hiero_, or _Tyrannicus_, in which the tyrant Hiero and the poet Simonides discuss the advantages and disadvantages of exercising tyranny. Included are a translation of the dialogue from its original Greek, a critique of Strauss’s commentary by the French philosopher Alexandre Kojève, and the complete correspondence between the two. This revised and expanded edition introduces important corrections throughout and expands Strauss’s restatement of his position in light of Kojève’s commentary to (...) bring it into conformity with the text as it was originally published in France.

Mindfulness is a large research field, involving disciplines such as philosophy, cognitive psychology, psychiatry, neuroscience, and Buddhist studies. Despite this widespread interest, one question remains unanswered: Is there a psychological capacity that is essential to mindfulness and which demarcates mindfulness from most other mental activities? The most promising idea is that mindfulness is a special form of metacognitive control. Yet, I argue that current proposals on how to conceptualize such metacognitive control fail. Instead, I propose a novel account of the (...) metacognitive control of mindfulness, drawing on the idea of so-called metacognitive goals. This account allows us to make sense of the explicit self-awareness and self-regulation involved in mindfulness and to separate mindfulness from exercises of more ordinary cognitive control. According to this account, metacognitive control is only a necessary and not a sufficient condition for mindfulness. Finally, I argue that the account motivates two theses on the nature of mindfulness, namely that we can reduce the metacognitive control of mindfulness to other psychological capacities and that this control is a form of mental action.

El propósito de la presente nota crítica consiste en examinar la concepción que Leo Strauss y José Ortega y Gasset elaboraron de la historia de la filosofía. Se trata, por tanto, de explorar la imagen que presentaron de dicha historia, una imagen de carácter general y que no repara en aspectos concretos. En la primera parte exponemos la concepción straussiana de la historia de la filosofía. En la segunda parte nos ocupamos de la concepción orteguiana de la historia de la (...) filosofía. Para concluir realizamos un análisis comparativo de una y otra concepción. (shrink)

En busca de comprender los cambios en la fecundidad en el Noroeste argentino, este estudio tiene por objetivo analizar su comportamiento entre 2015 y 2020. La investigación se justifica por la relevancia de examinar cómo ha evolucionado en los últimos años en la región. Mediante un análisis cuantitativo y descriptivo, a partir de los datos obtenidos del Departamento de Estadísticas e Información de la Salud (DEIS), se calcularon Tasas Específicas de Fecundidad (TEF) y Tasas Globales de Fecundidad (TGF). Las TGF (...) fueron categorizadas entre aquellas que se situaron por debajo de 2.1 (nivel de reemplazo), 1.6 (nivel de baja fecundidad) y 1.3 (nivel de muy baja fecundidad) hijos en promedio por mujer. Se aplicaron los modelos de baja fecundidad que la ONU propuso en 1963 para analizar las TEF, identificando tres regímenes de fecundidad: temprano, dilatado y tardío. Se observó el cambio en las TEF de 15 a 19 años y su relación con el resto de los grupos etarios. Los resultados revelan que, durante el periodo 2015-2020, la fecundidad en el promedio regional y en las provincias del NOA experimentó un pronunciado descenso; que las TGF se situaron por debajo del umbral mínimo de reemplazo, e incluso en algunos casos alcanzaron niveles de baja y muy baja fecundidad, oscilando entre 1.6 y 1.3 hijos en promedio por mujer; y que se produjo una concentración de los nacimientos en el grupo de mujeres de 25 a 29 años.

There is an unresolved conflict concerning the normative nature of desire. Some authors take rational desire to differ from rational belief in being a normatively unconstrained attitude. Others insist that rational desire seems plausibly subject to several consistency norms. This article argues that the correct analysis of this conflict of conative normativity leads us to acknowledge intrinsic and extrinsic reasons to desire. If sound, this point helps us to unveil a fundamental aspect of desire, namely, that we cannot desire at (...) will. Unlike belief, however, desire can unproblematically accommodate a notion of instrumental attitude. (shrink)

Sometimes Strauss argues as if he thought it possible to understand man without raising questions about his relations to other things, and hence about his place in the whole. But when they are viewed in their broader context, such arguments are seen not to be his final word. Man's humanity cannot be understood in its own terms alone. The human soul differs from everything else in that it is "... open to the whole and therefore more akin to the whole (...) than anything else is." In ordinary usage, "whole" implies completeness and autonomy. But the openness of the soul--i.e., of a part--to the whole can only mean that the whole is open to itself. The whole is, then, not, in the ordinary sense of the term, whole. Nor is the soul which is "open" to it. Stripped of myths, "... the human soul is... more akin to the whole than anything else is" because neither of them is whole. The same conclusion follows when one tries to understand the definition of the philosopher as the man animated by quest for knowledge of the whole. Qua philosopher he knows neither that there is a whole, nor what it might be if there were one. To define the philosopher as the man who knows that he does not know only paraphrases the difficulty. It does not solve it. For "know" is here used equivocally. The same equivocation is at play in the comment "... one cannot know that one does not know without knowing what one does not know". Admittedly "knowledge of ignorance is not ignorance." The philosopher believes and perhaps divines more than he actually knows. All men do. The essential difference between the philosopher and other men may well consist in the fact that the philosopher distinguishes more conscientiously than do others between what he knows and what he believes, and that he strives more single-mindedly than do they to transform as large a share of his beliefs as possible into knowledge. He may conceivably at some point be said to have reached the stage where his aspirations have become reasoned expectations. But that is as far as he can possibly go as long as he remains a philosopher and has not become a wise man or a god. Until and unless the philosopher knows, in the strong sense of the term, he can no more decide whether his aspirations could be fulfilled than he can swim before getting wet. (shrink)

Se presenta la fase inicial de una investigación que trata la despoblación como tema controversial desde una perspectiva interdisciplinar y tratando de identificar el valor de la Historia para el conocimiento de esta temática. Esta primera fase se plantea desde un cuestionario destinado a identificar la percepción del alumnado de Segundo curso de ESO sobre el aprendizaje de la Historia y su relación con temas del presente, su percepción sobre la despoblación y su opinión sobre tópicos. En este artículo se (...) analizan tres preguntas del cuestionario para identificar si existen diferentes percepciones en el ámbito urbano y rural y también entre centros y su ubicación. Mediante un análisis mixto se plantea la detección de diferencias de percepción tanto entre el alumnado de las ciudades de Segovia y Madrid como entre cada uno de los centros. (shrink)

Gender discrimination continues to be a problem in organizations. It is therefore important that organizations use performance evaluation methods that ensure equal opportunities for men and women. This article reports the results of an experiment to investigate whether and, if so, how the gender of the rater and that of the ratee moderate the relationship between the level of subjectivity in performance appraisals and organizational attractiveness. Participants in the experiment were 313 undergraduate students. We predicted, and indeed established, that as (...) the probability increases that employee performance is evaluated by a female manager, women expect more positive outcomes of subjective, but not objective evaluation processes. Our data did not support our expectation that as the probability of being evaluated by a female manager increases, men expect less positive outcomes of subjective evaluation processes. The findings of this study contribute to our understanding of why women are over-represented in jobs with objective formula-based reward systems, such as piece-rate systems. They are also of interest to organizations that are looking for more ethical human resource management practices. (shrink)
