Descartes posee una visión práctica de la medicina encaminada a la conservación de la salud. Acorde a dicho cometido, los fármacos que hallamos en el Remedia et vires medicamentorum y en su Excerpta anatomica desempeñan un importante papel, en tanto que conforman los instrumentos que posibilitan recuperar la salud ante distintas enfermedades. El presente artículo se propone examinar dichos remedios, dilucidando su estatuto en la medicina cartesiana y su posible origen en farmacopeas clásicas.

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.

Este artículo analiza las estrategias utilizadas por Descartes para «desencantar el mundo», a fin de suprimir los elementos herméticos de las explicaciones científicas cartesianas y someter todos los fenómenos naturales a nuestro control. Para ello, apelo a la distinción entre elementos causales —cualidades ocultas— y sus efectos —efectos admirables— como las dos dimensiones que deben ser incorporadas bajo las explicaciones científicas para garantizar el cálculo de los fenómenos y su dominio.

Questions like “Do you believe that p?” can be meant deliberatively (i.e., the question whether to believe that p) or self‐ascriptively (i.e., the question whether the addressee already believes that p). Therefore, an utterance of “I believe that p” can be a proper answer either to a deliberative or to a self‐ascriptive question. In the latter case, an utterance of “I believe that p” is a self‐ascription of belief, but in the former case, it is not. Instead, it is an (...) episode of the belief formed by deliberation. In failing to make these distinctions, contemporary discussions of the transparency of belief mistakenly assume that a proper answer to questions like “Do you believe that p?” is always a self‐ascription of belief. Adhering to the distinctions results in a better account of the transparency of belief. (shrink)

An obstacle for the attribution of self-consciousness to animals is that they lack the linguistic ability to use the first-person pronoun. To overcome the obstacle, current tests rely on the availability of behavioural measures of self-consciousness in the absence of language. However, this is not sufficient, for unless a distinction is drawn between epistemic and expressive varieties of self-consciousness, further puzzles threaten the validity of the research. This paper defends the distinction and shows how to re-evaluate current research into animal (...) self-consciousness in its light, so as to improve conceptual clarity in this area. (shrink)

RESUMENLa interpretación actual de la ciencia cartesiana ya no concibe ésta como una mera deducción desde los principios metafísicos, sino que reivindica el papel de la experiencia en ella. El presente artículo tratará de dar un paso más, defendiendo que existe una dimensión instrumental en la ciencia cartesiana. Para ello, se analizará la modificación que Descartes realiza en la Dióptrica de la relación artificial-natural y que posibilita una lectura instrumentalista.PALABRAS CLAVEDESCARTES, ARTIFICIAL, NATURAL, INSTRUMENTALISMO, CIENCIAABSTRACTThe current interpretation of the Cartesian science (...) no longer sees it as a mere deduction from the metaphysical principles, but claims the role of experience in it. This paper will try to go one step further, arguing that there is an instrumental dimension in the Cartesian science.

El hábito cartesiano constituye el elemento clave que posibilita la implantación de determinadas regularidades en mente y cuerpo, facilitando la intervención del sujeto en ambas dimensiones. Así, se observa cómo el hábito juega un importante papel en propuestas cartesianas centrales ― la asunción del método, los prejuicios de la infancia o la educación de las pasiones―, de forma que toda comprensión que se dirija a examinar éstas, deberá referirse previamente al concepto cartesiano de hábito. El presente artículo tratará, en consecuencia, (...) de elucidar el sentido de hábito. Para ello se efectuará una distinción entre los tipos de movimientos encargados de generar distintos hábitos y las diversas formas de memoria que permiten preservar las conexiones sobre las que éste se genera. Una vez ofrecida esta explicación sobre cómo se producen los hábitos, se propondrá una categorización apelando a la distinción establecida por Descartes entre alma y cuerpo. (shrink)

La epistemología contemporánea sostiene la imagen de Descartes como un fundamentalista epistemológico clásico, apelando, para ello, a las certezas metafísicas y a la presunta deducción del resto de conocimiento a partir de dichos principios. Con todo, un examen más detallado del proyecto epistemológico cartesiano pone en cuestión esta interpretación. El presente artículo analiza el papel de la deducción y la certeza moral a fin de redefinir el fundamentalismo de Descartes en términos moderados.

The objective of this paper is to discuss the nature of nonconceptual, as opposed to conceptual, states and their content, by exploring the suggestion that the distinction between the conceptual and the nonconceptual be mapped onto the distinction between the linguistic and the nonlinguistic. This approach gives special relevance to our intuitions about the cognitive relationship between small children and adults, especially regarding the acquisition of concepts, in the course of normal cognitive development. Assuming that there is a developmental challenge (...) to be met, the paper considers both the conceptualist and nonconceptualist strategies used to meet it; and concludes that conceptualism is a more satisfying option.

The topic of this paper is the conceptual possibility of being someone else. This thought occurs in the first person, and in principle it could be entertained by any subject of experience. The paper will focus on the examination of the content of such a thought: i.e., what exactly is meant by the possibility of being someone else? By way of comparing this thought with other possibilities (e.g., the possibility of being taller), it will be shown that the possibility of (...) being someone else lacks coherence, mainly because it goes against many reasonable and well-established beliefs held about ourselves and our identity.

RESUMEN La interpretación habitual de Descartes sostiene que la nueva ciencia cartesiana es resultado del remplazo, en las explicaciones científicas, de las causas finales y formales por las causas eficientes. Si bien dicha afirmación en líneas generales es correcta, se ha tendido a asumir que las causas eficientes no entrañan problema alguno. Este artículo desea cuestionar dicha asunción, poniendo de manifiesto una serie de problemáticas concernientes a la cognoscibilidad de las causas eficientes. ABSTRACT The common interpretation of Descartes argues that (...) the new science is a result of Cartesian replacement, in scientific explanations, of the final and formal causes by the efficient causes. While this statement is broadly correct, it has tended to assume that efficient causes do not imply any problem. This paper wishes to question this assumption, showing a number of problems concerning the knowability of efficient causes. (shrink)

Contemporary literature distinguishes two ways to defend the claim that cognition is a matter of representations: one, cognition involves representation-hungry tasks; two, cognition involves a complex form of informational covariation between subcomponents of a system with an adaptive function. Each of these conceptions involves a different notion of representation, and promotes a particular view of the architecture of cognition. But despite the differences, each of them aims to support the claim that cognition is a matter of representations on architectural constraints. (...) The objective of this article is twofold: one, it is argued that architectural constraints do not entail either of those two ways to defend the claim that cognition is a matter of representations; two, it is claimed that both notions of representation share an objectionable common element – namely, the idea of a model that grounds the representational reading– that must be abandoned, in favor of a more economical explanation in terms of causal relations, in order to get a clear view of cognition.

Recommending the identity of bidders in public procurement auctions has a significant impact in many areas of public procurement, but it has not yet been studied in depth. A bidders recommender would be a very beneficial tool because a supplier can search appropriate tenders and, vice versa, a public procurement agency can discover automatically unknown companies which are suitable for its tender. This paper develops a pioneering algorithm to recommend potential bidders using a machine learning method, particularly a random forest (...) classifier. The bidders recommender is described theoretically, so it can be implemented or adapted to any particular situation. It has been successfully validated with a case study: an actual Spanish tender dataset which has 102,087 tenders from 2014 to 2020 and a company dataset which has 1,353,213 Spanish companies. Quantitative, graphical, and statistical descriptions of both datasets are presented. The results of the case study were satisfactory: the winning bidding company is within the recommended companies group, from 24% to 38% of the tenders, according to different test conditions and scenarios.

With the advance of biomedicine, certain individuals and groups are vulnerable because of their incapacities to defend themselves. The International Bioethics Committee as a UNESCO working group has for the last several years dedicated to deepen this principle of human vulnerability and personal integrity. This book serves to supplement this effort with a religious perspective given a great number of the world's population is affiliated with some religious traditions. While there is diversity within each of these traditions, all of them (...) carry in them the mission to protect the weak, the underprivileged, and the poor. Thus, here presented is a collection of papers written by bioethics experts from six major world religions-Buddhism, Christianity, Confucianism, Hinduism, Islam, and Judaism-who were gathered to discuss the meaning and implications of the principle of vulnerability in their respective traditions.

Con una indagación cualitativa se intenta averiguar si el método de palabras generatrices de Paulo Freire presenta ventajas para la enseñanza-aprendizaje de la lengua escrita castellana en la edad infantil. Se extraen los datos de la experiencia práctica acumulada por profesorado que lo ha aplicado en el segundo ciclo. Cinco maestras aportan informes escritos individuales y dos equipos docentes se constituyen en grupos de discusión. Tras la categorización y análisis de los datos, se concluye que el método tiene muchas ventajas. (...) Entre las ventajas de tipo didáctico cabe resaltar el respeto al protagonismo del alumnado y a su pensamiento sincrético, ser muy motivador, conseguir la comprensión lectora desde el principio, desarrollar simultáneamente las conciencias léxica, silábica y fonológica; enriquecer el vocabulario, fijar una ortografía correcta, integrar todos los ámbitos de conocimiento, y desarrollar la capacidad simbólica y la creatividad. Como ventajas de tipo pedagógico: considerar los efectos de tipo actitudinal que actúan sobre los procesos cognoscitivos, adaptarse a los contextos, permitir al profesorado conocer mejor a su alumnado, propiciar el desarrollo de la dimensión afectivo-emocional, favorecer la socialización por trabajarse siempre en grupo y la ayuda entre iguales, el buen clima de aprendizaje y la colaboración familiar.

Psychosocial work factors are implicated in the development of stress and job satisfaction. This relationship has been scarcely studied in so-called singular activities, as is the case of professional drivers. This cross-sectional study of 601 professional drivers assesses psychosocial risks and job satisfaction using Copenhagen Psychosocial Questionnaire and Overall Job Satisfaction questionnaire models. The values of the psychosocial scales of professional drivers were compared with thresholds values of the Spanish working population. The relationships of the psychosocial scales with the level (...) of job satisfaction were examined using logistic regression models, adjusted for age, gender, length of driving license and years of experience. In general, professional drivers have an unfavorable psychosocial environment compared to the average Spanish workers. The relationship between psychosocial scales and job satisfaction is observed, with the most influential variables being the meaning and development of work, integration in the company, social relations, esteem and level of psychological demands.

The disease brought about by the SARS-CoV-2, COVID-19 coronavirus has had an unprecedented global impact. Confinement to control the outbreak may have mental health consequences for the most vulnerable in the population, including adolescents. This study aims to describe and analyze the relationships between the stress variables, Emotional Intelligence and the intention to use cannabis in healthy adolescents, before and after the end of the COVID-19 pandemic containment stage. A comparative correlational study was carried out with validated self-completed questionnaires through (...) an online platform. The sample is made up of adolescents aged 13–17 from two different schools in Ponferrada. The analysis of correlation and differences between the groups indicate that confinement has had effects on the mental health of the adolescents, specifically on the emotional manifestations of stress. Furthermore, significant gender differences were found for stress values and Emotional Intelligence. However, no differences have been found for cannabis use intention. (shrink)

The assembly of products or components by operators in industries is a complex task with recurring problems. In these processes, operators often make errors that can lead to defective products. Therefore, they need to be inspected later to verify their correct assembly. The main problems are caused by several reasons including high employee turnover, lack of experience in manufacturing specific products or confusion in interpreting instructions to assemble similar components. In this paper, a novel structured language aimed to describe the (...) required actions to manufacture a product in industrial assembly environments is presented. The main contribution is to provide a formal language to feed automatic systems that can verify through visual control whether the actions performed by the operator are carried out following the standard described by this language. In general, the use of this formal language will allow to minimize the negative impact of errors during assembly and to reduce waste in many forms in the industry. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:The Knock at the Door: Utopian Dreams for Post-Covid TimesPedro Mora-Ramírez, María Amo-Hernández, and Paula García-RodríguezAnswering the Knock at the Door, Welcoming Utopian Futures, The Knock at the Door: Utopian Dreams for Post-Covid Times, May 21–24, 2023, University of Huelva, Spain, and University of Calgary, CanadaThe COVID-19 pandemic has fostered new adversities and vulnerabilities, prompting reflection on the economic, social, and political paradigms that endanger human and nonhuman (...) lives. For many, it was anxiety and uncertainty that “knock[ed] at the door”; for others, however, those same feelings of unease prompted one of hopefulness: reflecting on the possibilities for resilience and regeneration in the process of changing our vision of the world.1 The Knock at the Door conference brought contemporary utopianism to the forefront of thinking about how to respond to global crises while remaining attentive to other adversities of daily life. Scholars and artists answered the knock in an attempt to examine paths toward utopia, and to take advantage of the regenerative and resilient potential of the present.The conference was the culmination of author/activist Larissa Lai’s fellowship period at the University of Huelva. The 2022–23 María Zambrano Fellowship for the academic year2 allowed Lai to complete the project “Utopian Dreams for Post-Covid Times,” carried out in collaboration with the Huelva research group led by Professor Pilar Cuder-Domínguez, who hosted a number of online and in-person seminars on speculative fiction with Lai. The Knock at the Door conference, marking the end of Lai’s fellowship, created yet another space for scholars, artists, and critics to discuss the potential of utopian narratives. Lai asks: “What does our cultural moment require, and how can we get where we need to go from where we are? How can literature, especially speculative fiction literature, help us get from here to there?”3 [End Page 641] The intention of the conference was to encourage others to continue Lai’s work on how to imagine futures where human and posthuman beings need to remain vigilant to adversities. Utopian scholars, among others, might find the complications of “getting there from here” closely related to Lai’s conception of “insurgent utopias,” or “emergent insurgency.” They could find Lai’s concept of “insurgent utopianism” interesting as it lays the foundations of futurity in terms of crisis responses.The aim of the conference was to explore the imagination of better futures through utopian thinking and practice. In addition, it focused on “the knock at the door,” which is “a moment of contingent arrival... open to cooptation, destruction, bastardization, incorporation, death, or defusal.” Yet, it presents “the powerful possibility of critique—narratively or discursively, in its very materiality.”4 One way of doing this might be to look back at the past century of utopianism and ask who or what has been missing. The conference took up Lai’s idea of insurgent utopianism as a method of paving a path toward a multitude of dreams and actions, all shaped by the unique circumstances of one’s positionality.After the COVID-19 pandemic, the need for utopian thinking has become more pressing than ever. New horizons of hope must be created in the face of emerging anxieties. In a world where anthropocentrism is showing signs of its deadly potential, conference participants reflected on the relevance of the utopian imagination to political resistance and resilience building.Utopian Visions: Contesting Better Worlds in Neoliberal and Feminist UtopiasThe first two panels of the conference addressed the critique of two dominant theoretical (and interrelated) frameworks: capitalism and neoliberalism. Speakers reflected on both in light of theoretical interventions by theorists Rosi Braidotti and Francesca Ferrando. Panelists Benjamin Ghan and Marc Lynch reflected on how creative writers envision ideal worlds and temporalities. In Ghan’s view, utopian narratives create a symphony of voices historically excluded from the category of “the human”: women; LGBTQ+ people; Indigenous peoples. In a similar vein, Lynch described his own novel, A Wasp’s Waist, as highlighting the impossibility of imagining utopias within the capitalist paradigm—and thus the necessity of imagining futures beyond capitalism, and beyond...

ABSTRACT:Ethical research on consumption has focused mainly on the obligations, principles and values guiding consumers' actions and reasons for action. In doing so, it has concerned itself mostly with such bounded contexts as voluntary simplifiers, anti-consumption movements or so-called ‘ethical consumers,’ thereby fostering an artificial opposition between ethical and non-ethical consumption. This paper proposes virtue ethics as a more apt conceptual framework for the ethical analysis of consumption because it takes into account the developmental dynamic triggered by engagement in consumption (...) practices. We build on MacIntyre's goods-virtues-practices-institutions framework and Beabout's concept of a domain-relative practice and argue that when engaging in consumption activities, agents may pursue goods internal to practices, further their individual life narratives and contribute to the good of their communities, thus developing virtues that perfect themselves both as consumers and as ethical agents.

Business ethics is one of the most significant demands made by institutional and individual investors, who usually require the participation of the board of directors in the planning and implementation of ethical behaviour in corporations. This is done by drawing up an ethics code and then monitoring its fulfilment. This study has a dual objective: first, to analyse the role played by the composition of the board of directors, and by that we mean its independence and the diversity of its (...) members, on the implementation and scope of an EC, and, second, to detect whether the corporate governance system moderates the level of involvement of the board in ethical issues. The findings obtained from a data panel sample made up of 760 listed companies from 12 countries for the years 2003–2009 show that the largest companies with large-sized and diverse boards implement the most developed ECs. Nevertheless, the extent of involvement of the independent directors is conditioned by the level of shareholder orientation characteristic of the system of CG in the corporation’s country of origin.

Introducción: Los cambios biológicos, sicológicos, económicos y sociales que se observan durante el envejecimiento conllevan a pensar que en los ancianos existe una serie de factores que favorecen la aparición de una depresión. Objetivo: evaluar la efectividad de una intervención sicológica para disminuir la depresión en adultos mayores de la Casa de abuelos "Dr. Diego Tamayo Figueredo", de Puerto Padre, en el período de noviembre de 2013 - mayo de 2014. Material y métodos: se realizó un estudio de intervención sicológica (...) en una muestra de 12 adultos mayores de la casa de abuelos. Se aplicó un programa de intervención sicológica, así como la Escala de Depresión Geriátrica para realizar la valoración antes y después de la intervención. Se empleó el modelo Cognitivo- Conductual de Beck. Los datos fueron tratados según la estadística descriptiva. Resultados: el porciento más elevado de pacientes correspondió al grupo de ancianos con edades entre los 60 y 90 años de edad. Respecto al sexo, el más frecuente es el masculino. El asma bronquial, la hipertensión arterial y la diabetes Mellitus representaron el mayor porciento de antecedentes patológicos personales. Conclusión: la intervención sicológica resultó efectiva pues se logró disminuir a leve los niveles iniciales de depresión establecida y los considerados con leve a no depresión, por lo tanto se afirma que con su aplicación fue modificado el estado emocional de los adultos mayores que se implicaron en la muestra. Introduction: Biological, psychological, financial and social changes observed during aging lead to think that there is a series of factors that favor the appearance of depression in senior citizens. Objective: Assessing the effectiveness of a psychological intervention in order to reduce depression in senior citizens from "Dr. Diego Tamayo Figueredo" Senior Citizens' House, Puerto Padre, from November 2013 to May 2014. Material and methods: A psychological intervention study was conducted on a sample of 12 senior citizens from the house. A psychological intervention program as well as the Geriatrics Depression Scale were applied before and after the intervention in order to make the assessment. The Beck's cognitive-behavior model was used. Data was processed according to descriptive statistics. Results: The highest percentage of patients corresponded to a group of seniors between 60 and 90 years of age. Regarding sex, males are more common. Bronchial asthma, arterial hypertension and diabetes mellitus represented the highest percentage of personal pathological history. Conclusion: The psychological intervention proved to be effective since initial established depression levels were reduced to minor and those considered as minor were reduced to no depression ; therefore, it is stated that its application modified the state of mind of the senior citizens involved in the sample.

La percepción clara y distinta es el elemento sobre el que se asienta la certeza metafísica de Descartes. Con todo, el planteamiento de los argumentos escépticos referidos a la duda metódica cartesiana ha evidenciado la necesidad de hallar una justificación al propio criterio de la percepción clara y distinta. Frente a los intentos basados en la indubitabilidad de la percepción o en la garantía surgida de la bondad divina, se defenderá una justificación alternativa pragmatista.

This article analyzes a panel of 550 international firms, for the period 2004 to 2010, to compare the role of female directors in family and non-family firms in promoting responsible practices. Many studies have associated the presence of women on the board with a higher degree of socially responsible commitment. However, we found that this is much less so in family firms than in non-family firms. In family firms, corporate social responsibility commitment does not vary significantly with the presence of (...) female directors, as the latter tend to behave in accordance with the family orientation toward CSR. This orientation depends on the stakeholders being addressed, with greater social responsibility shown toward external stakeholders than internal ones. (shrink)

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)
