La observación del cinismo antiguo como precursor filosófico del anarquismo ha sido abordada por un gran número de estudiosos y especialistas de ambos campos. El siguiente trabajo se propone aportar nuevos puntos de vista a la relación cinismo-anarquismo. Nuestro punto de partida es la figura del protocínico Diógenes de Sinope [412-402 /325-321], cuya heterodoxa filosofía, de la que no conservamos escritos, ha sido objeto de ambivalentes recepciones a lo largo de la historia. Veremos por qué ha sido reivindicado como un (...) miembro ilustre de la prehistoria del anarquismo y qué nuevas perspectivas podemos añadir a esos estudios. (shrink)

The aim of this work is to analyse the concept of semi-sentence from a linguistic, formal and computational point of view. A semi-sentence can be characterised as a sentence which, from a grammatical perspective, is neither absolutely correct nor incorrect . This study focuses on: - a characterisation of the semi-sentences in the setting of the grammar of a language. This study will help to analyse in depth the concept of grammaticality [3]; - the correlate of semi-sentences in formal languages, (...) i.e., semi-strings, which arise from applying productions that deviate from that which is strictly permitted by the rules of grammar [6]; - a Prolog program for handling semi-grammaticality in a computational manner [2].

The past decade has seen a flurry of social scientific research on the use of racial categories in human genetics research. This literature has critically analyzed how U.S. race relations are being shaped by and themselves shaping research on human biological difference and disease. Recent work, however, suggests that the particular configurations of science and ethnoracial politics in the US are not exportable. Instead, research on human biology in other contexts reveals the importance of not just racial categories, but national, (...) ethnic, regional and linguistic classifications of bodies and communities...

Populism has become one of the most worrying political phenomena, and given its complexity, one of the most controversial and debated today in social sciences. This article deconstructs and compares the discourses of the Spanish parties that are generally classified as populist —the left-leaning Podemos, the right-wing Vox and the Basque and Catalan secessionist parties EH Bildu, Esquerra Republicana de Catalunya and Junts per Catalunya— according to five dimensions of populism: i) antagonism, ii) morality, iii) idealised construction of society, iv) (...) exaltation of popular sovereignty, and v) personalist leadership. This article shows that, despite significant ideological and programmatic differences, all these parties share many discursive features and a similar way of articulating their communications, interpreting social and political dynamics, as well as instrumentalizing crises to build new political identities.

Propaganda has been historically used for the benefit of certain social groups faced up to another. This propaganda is not always ethical at all. It is based on misconceptions, lies, and fallacies. We have analyzed (by using an experimental Psychology task) the presence and cognitive weight of certain mental footnotes and their influence on the Reasoning of Hispanic-Americans (Ecuadorian). These mental footnotes have been extracted from the classical work “A brief account of the destruction of the Indies” of Bartolomé de (...) las Casas in 1552. The most relevant and significant finding of this study is the clear evidence that nowadays we can still find these historical falsehoods in the current cognitive system of Ecuadorian people which are product of a well-planned and maliciously orchestrated propaganda. We conclude that all the contents of the Spanish black legend are the consequences of the aspirations of some social sectors to boycott the Spanish culture. (shrink)

ABSTRACT In Mexico informed consent is a legal requirement that ensures that patients who are invited to participate in clinical trials are provided with all the information needed to decide whether to participate, or not, in a research protocol. To improve our understanding of the problems physicians in developing countries encounter, when obtaining informed consent (IC), we examined their opinion on the importance of IC in clinical research, the quantity and quality of the information provided to the participant, and the (...) conditions in which the IC is obtained. Investigators considered that IC was useful to the patients, providing information that helped the patient to make a decision about his/her participation. Nevertheless, they felt that for some aspects of the research, like drug development in general, the use of placebos, and the randomization process, many of the patients were not capable of fully understanding the information provided, referring to the complexity of the information and illiteracy as the main reasons. Many investigators were not acquainted with some of the guidelines established in the Mexican General Law of Health,1 36% of them admitting to not having completed their IC letters. Most investigators gave only minutes to the patient to make a decision and 20% of ICs were obtained while the patient was hospitalized. Except for one investigator, all of them considered that specific training in medical ethics would be useful for the daily clinical work. (shrink)

The purpose of this article is to analyze Spanish first-person plural subjects as a cognitively grounded grammatical choice serving various discursive functions. Both the expressed and omitted variants of the subject will be considered, even if omission is by far the more frequent choice in Spanish and the more communicatively versatile one. The particularly vague reference of omitted nosotros ‘we’ – always involving an extension of the self towards a wider notional scope – results in a remarkable variety of possible (...) contextual projections. It can be used to signal speaker identities as well as manage interpersonal relationships through the iconic suggestion of viewpoint coincidence. First-person plural clauses are quantitatively and qualitatively investigated across two corpora of contemporary Spanish comprising a variety of spoken and written genres. It is found that, aside from the basic distinction between hearer-exclusive and hearer-inclusive first persons, a third, intermediate variant can be considered, that of empathic hearer-exclusive uses. These are typical of interactions where involvement of the audience is sought even if they are not referentially included in the subject, as is usual in some varieties of spoken mass-media discourse. Each one of the referential variants is used with different frequencies and contextual repercussions, depending on the socio-functional demands and goals of particular textual genres. (shrink)

This volume brings together work in free will, ethics, metaethics, feminist theory, disability studies, experimental philosophy, and psychology. The theme for both the workshop and these papers was “Non-Ideal Agency and Responsibility,” and in these essays, our authors take a number of different and creative angles on this theme. Roughly half of the essays fall under the rubric of non-ideal agency. They discuss ways in which our agency is impacted by inherent psychological limitations, by the social contexts in which we (...) act, or by different ways in which our abilities can break down. The other half fall under the rubric of non-ideal responsibility. They discuss both the modes by which we assess imperfect exercises of our agency and the ways in which common forms of assessment are themselves imperfect. (shrink)

The struggle for the recognition of indigenous rights is one of the most important social movements in Mexico. Before the 1970s, existing peasant organizations did not represent indigenous concerns. Since 1975 there has been a resurgence of indigenous movements and have raised new demands and defense of their cultural values. However, indigenous social mobilization had been laid in local and regional peasant struggles across the 1970s and 1980s. Also the indigenous movement is not homogeneous and does not include all ethnic (...) groups in the country, but it has many different expressions and encompasses different entities at local, regional and national levels. This paper aims to analyze the historical social approach and under the frame of indigenous political ecology of social movements for recognition of indigenous rights in contemporary Mexico.

The primary goal of the present research was to determine the order of swimmers on a mixed relay team that would ensure the best performance in the Fédération Internationale de Natation World Championships held in Kazan, Budapest, and Gwangju. The data were obtained from database websites for the 4 × 100 m freestyle and 4 × 100 m medley official results,1 including 660 records from 188 entries of finals and 472 preliminary events. The results showed that the fastest swimmers were (...) located primarily in the first or second positions of the freestyle relay. The most successful gender strategy for the 4 × 100 m freestyle and for the 4 × 100 m medley relays was the order male-male-female-female, although no statistical differences were found for the medley relays. In the 4 × 100 m freestyle, the second and third relay legs had a statistical effect on the total relay time, whereas in the 4 × 100 m medley, all four relay legs had a statistical effect on the final performance, the weight of the four strokes being different in heats with respect to the final round. Also, a later position of the first female swimmer or the consecutive position of two female swimmers in the team order significantly affected the relay performance in specific events. Mixed relay events appeared to present specific strategies in comparison to traditional male- or female-only relay lineups. (shrink)

El acercamiento al conocimiento de la naturaleza requiere una metodología adecuada. En este artículo presento la descripción madura que hace Peirce del método científico articulándolo a partir de los tres modos de inferencia. Esta descripción tiene la ventaja de ser muy clara, ya que asigna un tipo de inferencia distinto a cada etapa del método.

The harmful consequences of fossil fuels use has resulted in the promotion of clean and renewable energies. During the past decades, green technologies have experienced a strong development, paying especial attention to wind energy, that covers a significant share of the electric energy demand. In this context, the main efforts are focused on the optimization of wind generator facilities, not only in the mechanic design but also in the energy management. Then, the present work deals with the prediction of the (...) energy generated in a small wind turbine placed in a bioclimatic house located on the north west region of Spain. This includes an analysis of the characteristics of the atmospheric variables registered during the turbine operation for a period of one year and an exploratory examination of a range of regression techniques in order to assess the suitability of using the registered information to predict the installation’s power generation levels on the short term. The study detailed in this work proves that this objective is an attainable one with a good degree of accuracy. (shrink)

El concepto de segunda naturaleza promete proporcionar una explicación de cómo la naturaleza y la razón se pueden reconciliar. Pero dicho concepto está cargado de ambigüedad: se entiende como aquello que une todas las actividades cognitivas y se concibe como un tipo de naturaleza que puede ser modificada por actividades cognitivas. Se intenta investigar esta ambigüedad distinguiendo una concepción kantiana de otra hegeliana. Se sostiene que la idea de una transformación de un ser de prim- era naturaleza en un ser (...) de segunda naturaleza, que se encuentra en el corazón de la concepción kantiana, es errónea. (shrink)

The emergent Coronavirus Disease 2019 caused by the Severe Acute Respiratory Syndrome Coronavirus 2 could produce a maternal immune activation via the inflammatory response during gestation that may impair fetal neurodevelopment and lead to postnatal and adulthood mental illness and behavioral dysfunctions. However, so far, limited evidence exists regarding long-term physiological, immunological, and neurodevelopmental modifications produced by the SARS-CoV-2 in the human maternal-fetal binomial and, particularly, in the offspring. Relevant findings derived from epidemiological and preclinical models show that a MIA (...) is indeed linked to an increased risk of neurodevelopmental disorders in the offspring. We hypothesize that a gestational infection triggered by SARS-CoV-2 increases the risks leading to neurodevelopmental disorders of the newborn, which can affect childhood and the long-term quality of life. In particular, disruption of either the maternal or the fetal cholinergic anti-inflammatory pathway could cause or exacerbate the severity of COVID-19 in the maternal-fetal binomial. From a translational perspective, in this paper, we discuss the possible manifestation of a MIA by SARS-CoV-2 and the subsequent neurodevelopmental disorders considering the role of the fetal-maternal cytokine cross-talk and the CAP. Specifically, we highlight the urgent need of preclinical studies as well as multicenter and international databanks of maternal-fetal psychophysiological data obtained pre-, during, and post-infection by SARS-CoV-2 from pregnant women and their offspring.

In explaining the outcome of the 2016 EU referendum in the United Kingdom, can theories emphasizing the importance of economic factors be reconciled with the fact that many people appeared to vote against their economic self-interest? This article approaches this puzzle through case study research that draws on fieldwork and a process of reciprocal knowledge exchange with local communities in five local authorities in England and Wales. It argues that the Leave vote can be attributed partly to political discontent associated (...) with trajectories of relative economic decline and deindustrialization. Building on the growing literature about the role of narratives and discourses in navigating uncertainty, it contends that these localized economic experiences, interpreted through local-level narratives, paved the way for local-level discourses of resilience and nationwide optimistic messaging about the economic impacts of Brexit to resonate. Local and national-level discourses discounting the potential economic costs of leaving the European Union played a crucial role in giving precise, somewhat paradoxical, political content to the sense of discontent. The article contributes to the growing focus on place and community in understanding political behavior and invites further research on local discourses linking macro-level trajectories and micro-level voting decisions.

El texto presenta la crítica heideggeriana a los conceptos de teoría y praxis, tal como han sido acuñados por la tradición filosófica. El artículo muestra el giro transformador que hace el filósofo alemán en el tratamiento de estas dos nociones, con el fin de delinear una nueva concepción de filosofía, a propósito de la crítica y transformación de estas concepciones. La crítica se centra en señalar cómo en la tradición filosófica ha preponderado la teoría, comprendida desde una visión lógico – (...) racional, y la comprensión de la praxis como una instancia a-teórica, lo que deja de lado las consideraciones prácticas centrales y primarias implicadas en el pensar, y el ejercicio práctico como instancia comprensiva y de pensamiento. En este sentido, se muestra la reivindicación de la praxis, de la cotidianidad y de la situación fáctica como aspectos de central importancia en el ser del Dasein; y se plantea una nueva comprensión de lo que implica la teoría y las nuevas relaciones que se establecen en el nexo teoría – praxis como posibilidades del ser del Dasein, sin caer en el primado de la una sobre la otra, lo que implica la transformación de sus modos de comprensión. Finalmente, se muestra cómo un ejercicio filosófico desde estas intuiciones se encuentra más cercano a la comprensión e interpretación práctica que al desarrollo de teorías en el sentido clásico del término.

The only test theory used by workers in the field of testing special relativity to analyze the significance of their experiments is the proof by H. P. Robertson [Rev. Mod. Phys. 21, 378 (1949)] of the Lorentz transformations from the results of the experimental evidence. Some researchers would argue that the proof contains an unwarranted assumption disguised as a convention about synchronization procedures. Others would say that alternative conventions are possible. In the present paper, no convention is used, but the (...) Lorentz transformations are still obtained using only the results of the experiments in Robertson's proof, namely the Michelson-Morley, Kennedy-Thorndike, and Ives-Stilwell experiments. Thus the revised proof is a valid test theory which is independent of any conventions, since one appeals only to the experimental evidence. The analysis of that evidence shows the directions in which efforts to test special relativity should go. Finally it is shown how the resulting test theory still has to be improved for consistency in the analysis of experiments with complicated experimental setups, how it can be simplified for expediency as to what should be tested, and how it should be completed for a missing step not considered by Robertson.

A connection viewed from the perspective of integration has the Bianchi identities as constraints. It is shown that the removal of these constraints admits a natural solution on manifolds endowed with a metric and teleparallelism. In the process, the equations of structure and the Bianchi identities take standard forms of field equations and conservation laws.The Levi-Civita (part of the) connection ends up as the potential for the gravity sector, where the source is geometric and tensorial and contains an explicit gravitational (...) contribution.Nonlinear field equations for the torsion result. In a “low-energy” approximation (linearity andlow energy-momentumtransfer), the postulate that only charge and velocities contribute to the source transforms these equations into the Maxwell system. Moreover, the affine geodesics become the equations of motion of special relativity with Lorentz force in the same approximation [J. G. Vargas,Found. Phys. 21, 379 (1991)]. The field equations for the torsion must then be viewed as applying to an electromagnetic/strong interaction.A classical unified theory thus arises where the underlying geometry confers their contrasting characters to Maxwell-Lorentz electrodynamics and to an Einstein's-like theory of gravity. The highly compact field equations must, however, be developed in phase-spacetime, since the connection is velocity-dependent, i.e., Finsler-like.Further opportunities for similarities with present-day physics are discussed: (a) teleparallelism allows for the formulation of the torsion sector of the theory as a flat space theory with concomitant point-dependent transformations; (b) spinors should replace Lorentz frames in their role as the subjects to which the connection refers; (c) the Dirac equation consistent with the frame bundle for a velocity-dependent metric with Lorentz signature generates a weak-like interaction in the torsion sector.

Microsystems are described as contexts formed by a subject, their roles, interactions, and a specific physical space and time, such as housing and the school environment. Although several studies suggest the importance of studying this type of environment and its repercussion on children's development, in a Latin American context few studies integrate the interaction of two primary settings in the development of executive functioning. The present study explores the effects of the quality of housing and school environments on the perception (...) of stress, decision making, and planning among children. A total of 114 children (43% girls and 57% boys, Mage = 10.57) from a primary school located in a community classified as poor participated in the study. It was measured: environmental quality of classrooms, housing, stress and executive functioning of children. The results reveal a model linking environmental quality levels in children's homes and schools and executive functioning. We also obtain a mediating role of stress between microsystems and performance, finding a deficit in executive performance when children experienced higher levels of stress as a result of poor environmental quality both in their homes and in their schools.

This paper develops the conjecture that the electromagnetic interaction is the manifestation of the torsion Ωμ of spacetime. This conjecture is made feasible by the natural separation of the connection ω μ v into “gravitational” and “electromagnetic” parts α μ v and β μ v , respectively, related to the metric and to the torsion. When α μ v is neglected in front of β μ v , the affine geodesics are shown to become the equations of motion of charged (...) particles with Lorentz force, for an appropriate choice of Ωμ. Since β μ v contains the factor q/m, neutral particles do not see the torsional part of the connection and behave as if Ωμ were zero, i.e., as in Einstein's theory of gravity (the same effect is obviously obtained for charged particles when β μ v 《 α μ v ).In addition to the factor q/m, the velocity of the test particle appears in Ωμ. This indicates that the appropriate context for this problem is to be found in velocity-dependent connections. The velocities are now coordinates and become the actual velocities of the test particles only in the system of equations that one solves for obtaining the affine geodesics in connections of this type.When written with differential forms, the combination of Maxwell's equations and of the pertinent form of the torsion suggests geometric field equations for electrodynamics. As for the gravitational part of the connection, it can be made to obey equations similar in form to the Einstein field equations. A unified geometric theory of electrodynamics and gravitation spontaneously emerges. The present state of the theory does not yet permit us to ascertain whether the right-hand side of the fully geometric, gravitational field equations corresponds to the energy-momentum tensor.

In a recent paper [J. G. Vargas and D. G. Torr, Found. Phys. 27, 599 (1997)], we have shown that a subset of the differential invariants that define teleparallel connections in spacetime generates a teleparallel Kaluza-Klein space (KKS) endowed with a very rich Clifford structure. A canonical Dirac equation hidden in this structure might be uncovered with the help of a teleparallel Kähler calculus in KKS. To bridge the gap to such a calculus from the existing Riemannian Kähler calculus (...) in spacetime, we commence the construction of a teleparallel Kähler calculus in spacetime. In the process, we notice: (a) Unknown to him, one of Einstein's equations in his attempt at unification with teleparallelism states that the interior covariant derivative of the torsion is zero. (b) A mechanism exists in the tangent bundle of teleparallel spaces for producing confinement (in the applicable cases, one would have to show why nonconfinement also occurs, rather than the other way around). (c) When the torsion is not zero, the interior covariant derivative in the sense of Kähler, δF, does not coincide with *d*F. The system (dF = 0, δF = j) rather than (dF = 0, *d*F = j) should then be used for generalizations of Maxwell's electrodynamics. (shrink)

We show that in 1929 Cartan and Einstein almost produced a theory in which the electromagnetic (EM) field constitutes the time-like 2-form part of the torsion of Finslerian teleparallel connections on pseudo-Riemannian metrics. The primitive state of the theory of these connections would not, and did not, permit Cartan and Einstein to realize how their torsion field equations contained the Maxwell system and how the Finslerian torsion contains the EM field. Cartan and Einstein discussed curvature field equations, though failing to (...) focus on the fact that teleparallelism automatically implies gravitational field equations with torsion terms as source, both in first and second order. We further show that the first-order contribution of the EM field to the source of the gravitational field may play havoc with the remeasurement of Newton's gravitational constant, even if the experiment is electrically grounded. These results are also used as support for the thesis that there is an alternative to the present way of dealing with the great theoretical questions of physics. On the practical side, the inconveniences faced in measuring G may be greatly compensated by the possibility of manipulating spacetime with electric fields at the first-order level. (shrink)
