El presente trabajo analiza la construcción del espacio caribeño en la novela Rastro de sal de la escritora costarricense Arabella Salaverry. Este espacio se aborda desde dos perspectivas específicas: una, vinculada con la representación general del espacio caribeño. Este análisis se centra en tres relaciones concretas: conectividad/aislamiento, naturaleza/cultura, centro/periferia. La segunda perspectiva se interesa más bien en los espacios domésticos y su interacción con los personajes femeninos, a partir de las relaciones libertad/prisión e interior/exterior. Se concluye que, en Rastro de (...) sal, el Caribe se presenta como un espacio contradictorio, dinámico y desigual. (shrink)

Populist representation is the process by which a body or set of bodies become the signifier of a powerful act of political transgression of the social order. We call this specific type of representative linkage ‘synecdochal representation’. In it, the leader’s body performs three key functions: it mirrors certain popular traits that are characterized as ‘low’, it displays marks of exceptionality, and it appropriates symbols of institutional power. These tasks are performed through particular ways of acting, dressing, talking, eating, and (...) the like, in public. Social media has become a key locus for bodily self-presentation because it is used to create the appearance of intimacy and spontaneity through the distribution of ‘candid’ pictures and videos. This paper will analyze how the self-presentation of populist and non-populist leaders are established through Twitter, what images they choose to disseminate, and how they are re-signified by the audience. To do so, we will focus on the two Latin American politicians: Cristina Fernández (with a populist style) and Mauricio Macri (with a technocratic one). (shrink)

Este escrito apunta a mostrar el camino histórico seguido por el conocimiento liberal y por la Universidad en la tradición educativa anglosajona. En este contexto de ideas, el campo de estudio ha sido limitado a los siguientes temas: primero, precisar, en términos generales, qué es la educación liberal y qué elementos componen su syllabus; segundo, describir las características esenciales que definen esta tradición educativa en el mundo anglosajón, principalmente en Inglaterra y en los Estados Unidos; y tercero, mostrar en qué (...) consiste la superioridad cualitativa de este tipo de educación.

We study some operations that may be defined using the minimum operator in the context of a Heyting algebra. Our motivation comes from the fact that 1) already known compatible operations, such as the successor by Kuznetsov, the minimum dense by Smetanich and the operation G by Gabbay may be defined in this way, though almost never explicitly noted in the literature; 2) defining operations in this way is equivalent, from a logical point of view, to two clauses, one corresponding (...) to an introduction rule and the other to an elimination rule, thus providing a manageable way to deal with these operations. Our main result is negative: all operations that arise turn out to be Heyting terms or the mentioned already known operations or operations interdefinable with them. However, it should be noted that some of the operations that arise may exist even if the known operations do not. We also study the extension of Priestley duality to Heyting algebras enriched with the new operations. (shrink)

Due to the COVID-19 Pandemic, several changes have been forcibly made and observed in various fields and areas of society, one of which include the field of education; the foundation of the formation of intellect and knowledge. After two years of studying indoors and private educational institutions holding virtual classes, the time has finally come for students to be re- adjusted once more to the blended mode of learning; a combination of virtual and in-person classes. Thus, this study aimed to (...) investigate the development of students’ study habits and how these habits could potentially affect the students’ academic achievement or performance. The study utilized a descriptivecorrelational design to examine the impact of study habits to the academic performance of 137 senior high school students. The study made use of the Palsane and Sharma’s Study Habits Inventory, or also known as PSSHI, and using this instrument, the study has been able to procure sufficient results that will answer the present study’s problems. Using linear regression analysis, the present study found that there was a significance between the study habits and academic performance of the senior high school students, thus the study’s null hypothesis was eventually rejected.

In both scientific and popular circles it is often said that we are in the midst of a sixth mass extinction. Although the urgency of our present environmental crises is not in doubt, such claims of a present mass extinction are highly controversial scientifically. Our aims are, first, to get to the bottom of this scientific debate by shedding philosophical light on the many conceptual and methodological challenges involved in answering this scientific question, and, second, to offer new philosophical perspectives (...) on what the value of asking this question has been — and whether that value persists today. We show that the conceptual challenges in defining ‘mass extinction’, uncertainties in past and present diversity assessments, and data incommensurabilities undermine a straightforward answer to the question of whether we are in, or entering, a sixth mass extinction today. More broadly we argue that an excessive focus on the mass extinction framing can be misleading for present conservation efforts and may lead us to miss out on the many other valuable insights that Earth’s deep time can offer in guiding our future.

In the present paper, we return to one of the main theses we already defended concerning the role of the tarskian truth notion within the semantic approach (CARNIER, 2022). As it was argued, this truth notion proves to be insufficient to be applied to scientific theories as they are conceived by this approach, i.e., as extralinguistic entities, because it is a property of sentences and because the tarskian truth of a sentence doesn't necessarily mean the world is as it describes, (...) which results in the fact that other truth conceptions more appropriate need to be articulated within the several members of the semanticist family, in order to characterize the relationship between theory and phenomenon. Our argument in this regard was based in a case study applied to constructive empiricism and quasi-realism, but in this paper we extend our analysis to structuralism, assuming and endorsing the position according to which this proposal may be considered a member of the semantic approach.

This study situates Henry Havelock Ellis’s sexological research within the nineteenth-century evolutionary debates, especially the discussion over sexual selection’s applicability to humanity. For example, Ellis’s monograph on sexual behavior, _Sexual Inversion_ (1897), treated inborn homosexuality as a natural variation of evolutionary mechanisms. This book was situated within a longer study of human sexuality in relation to evolutionary selection. His later works dealt even more directly with Charles Darwin’s concept of selection, such as _Sexual Selection in Man_ (1905). Through _Sexual Selection (...) in Man_, Ellis asserted that sexual attraction stemmed from a physical cause rather than an innate aesthetic sense. I argue that Ellis’s best-known historical publications, including his work on sexual inversion, were intended to intervene in the contemporary evolutionary debates. This analysis also identifies a specific point where evolutionary theory informed the foundation of sexology as a scientific discipline. (shrink)

Analizaremos algunos rasgos del proceso de transformación económica y social que tuvo lugar en al-Andalus entre los siglos X y XII, en el marco de la «revolución económica» de la Europa plenomedieval, tomando como caso de estudio la región oriental de la península ibérica. El proceso debió de arrancar con un despegue demográfico y con el aumento de la productividad agrícola, en este caso derivado de los progresos técnicos asociados a la llamada «revolución verde» islámica de los siglos VIII al (...) X. El incremento creciente de los beneficios derivados del campo y el interés por aprovecharlos seguramente impulsó la coacción de las élites urbanas sobre las comunidades campesinas para arrebatarles las tierras más rentables. También pudo ocasionar la colonización de áreas rurales menos favorecidas, que hasta ese momento habían permanecido incultas, por parte de esos grupos acomodados que buscaban expandir los cultivos comerciales, así como por familias de campesinos desposeídos de las mejores tierras. Los cambios en el mundo rural influyeron en el crecimiento de las ciudades debido a la inmigración de la población del campo, presionada y desplazada, que se incorporaba como proletariado urbano ante el incremento en la demanda de manufacturas y bienes de consumo por parte de los terratenientes enriquecidos que habitaban esas ciudades.

The aim of this paper is to show that any process of benefit sharing that does not guarantee the representation and participation of women in the decision-making process, as well as in the distribution of benefits, contravenes a central demand of social justice. It is argued that women, particularly in developing countries, can be excluded from benefits derived from genetic research because of existing social structures that promote and maintain discrimination. The paper describes how the structural problem of gender-based inequity (...) can impact on benefit sharing processes. At the same time, examples are given of poor women’s ability to organise themselves and to achieve social benefits for entire communities. Relevant international guidelines (e.g. the Convention on Biodiversity) recognise the importance of women’s contributions to the protection of biodiversity and thereby, implicitly, their right to a share of the benefits, but no mechanism is outlined on how to bring this about. The authors make a clear recommendation to ensure women’s participation in benefit sharing negotiations by demanding seats at the negotiation table. (shrink)

RESUMEN El presente trabajo de revisión expone cómo las prácticas de gestión en la anestesiología deben ser modificadas para encarar las cambiantes necesidades de pacientes, otros profesionales y sistemas sanitarios, a fin de mantener una función significativa en la atención sanitaria. Los servicios de anestesia han adoptado una amplia variedad de modelos para hacer frente a las necesidades del medio local, la relación entre los anestesiólogos y la comunidad, y los papeles desempeñados por los anestesiólogos en el tratamiento perioperatorio. El (...) sistema sanitario cubano se encuentra inmerso en un proceso de permanente adecuación de sus servicios a los problemas, demandas y necesidades de la población cubana y sus determinantes. Por ello, objetivo es exponer consideraciones teóricas en función del perfeccionamiento del servicio de Anestesiología y Reanimación. ABSTRACT This review paper presents how anesthesiology management practices must be modified in order to deal with the changing needs patients, other professionals and health systems have, in order to maintain a significant function in health care. Anesthesiology services have adopted a wide variety of models to face up to the needs the city, the relationship between anesthesiologists and the community and the role anesthesiologists play in perioperative treatment have. The Cuban health system services are in a process of permanent adaptation to the problems, demands and needs the Cuban population and its determinants have. For that reason, this paper aims at presenting theoretical considerations towards the improvement of the Anesthesiology and Resuscitation service. (shrink)

In this paper, two different philosophical proposals to introduce and carry out philosophy in school spaces which include the participation of children are compared, these are: Philosophy for Children, mainly developed by Matthew Lipman and Ann Sharp, and Philosophy with Children, which is actually a set of “second generation” proposals –as described by Vansieleghem and Kennedy, based on Reed and Johnson –, among which those created by Walter Kohan and Karin Murris, to mention a few, stand out. The text begins (...) with some similarities between both proposals, before comparing them in each of their dimensions. First, P4C is discussed. Second, PwC. Their ideas about education, school, philosophical education, their concept of childhood, the role given to teachers and their relation with politics are the main focus. Third, PwC’s critique of the P4C programme is studied. Finally, the paper concludes with some ideas on the issue of introducing philosophy to the school space. Particularly, PwC’s proposal is supported, fundamentally because of its coherent acknowledgment of the autonomy of teachers and of the political element in education, since philosophical experience with children is particularly questioning, defying, and, therefore, it has the possibility of bringing about important transformations, both at a personal-individual level, as well as a collective one.

The purpose of this article is to show how the use of certain terms of theatre, that are employed to describe philosophical procedures or concepts, reveals two different kinds of relations between philosophical discourse and artistic practices: On the one hand, some philosophers make a conscious and metaphorical use of the vocabulary of scenic practices to describe their own operations; on the other, the technical and historical determinations of these practices open up new interpretations of philosophical constructs, even though, at (...) first, they were not intended to do so by the authors that exploit them. To fulfil this purpose, this article analyzes significant moments of contemporary French thought—where there are frequent expressions such as scene and dramaturgy—, in order to trace the genealogy of that philosophical interest and explore a series of descriptions of the theory and practice of classical French theatre.

En este trabajo realizo un examen crítico del reciente libro de Silvana Gabriela Di Camillo sobre la crítica de Aristóteles a la teoría platónica de las Ideas. El libro de Di Camillo es un trabajo muy serio cuya lectura recomiendo ampliamente. Sin embargo, considero que cuatro de las principales tesis que la autora defiende tienen varias dificultades y mi objetivo aquí es presentar argumentos detallados en contra de ellas: la interpretación de la distinción entre argumentos más y menos rigurosos del (...) tratado Sobre las Ideas; la tesis de que la separación es el blanco esencial de las críticas aristotélicas a las Ideas; la interpretación de las opciones que Platón tiene para responder al argumento del tercer hombre, y la tesis de que la separación de las Ideas debe entenderse como homonimia. In this paper I examine Silvana Gabriela Di Camillo's recent book on Aristotle's criticisms of Plato's theory of Ideas. Di Camillo's book is a very serious work that I highly recommend. Nevertheless, I consider that four of the main theses that the author defends face several difficulties and my aim here is to offer detailed arguments against them: the interpretation of the distinction between more and less accurate arguments of the treatise On Ideas; the thesis that separation is the essential target of Aristotle's criticisms against Plato's Ideas; the interpretation of the options available to Plato to reply to the third man argument; and the thesis that the separation of Ideas should be understood as homonymy.

The nanotechnologies and nanomaterials sector is a huge and growing industry. The amount of legislation already in place and still to be produced in order to regulate it will be very substantial. What process is used to produce such regulation? The answer is that very diverse regulatory approaches are and will be used. The approach taken by the European Commission diverges from the one taken by the European Parliament. Moreover, at national level, Member States add their own contribution to the (...) process. This article attempts to describe the landscape and various regulatory actions that have been undertaken by all these actors in the European Union. It first describes the role played by the European Commission and Parliament. It then looks at specific regulatory initiatives from a more sectoral perspective: Cosmetics, Food information, Restriction of the Use of Certain Hazardous Substances in Electrical and Electronic Equipment, Waste Electrical and Electronic Equipment and Biocides. The third part of the paper describes some major national initiatives, in particular those concerning the establishment of reporting systems for nanomaterials, mixtures, articles and consumer products containing them, as an example of how to improve the current governance in the EU and to prevent the risks to human health and the environment. The fourth part gives the perspective of the European Trade Union Confederation. Finally it presents some conclusions and policy recommendations, taking into consideration the diversity of regulatory approaches. (shrink)

Este artículo examina la doctrina del Idealismo Trascendental de Kant en relación con el Problema del Mundo Externo, abordándola desde la perspectiva de la Filosofía de la Percepción. La investigación propone que hay argumentos sólidos para evaluar la doctrina kantiana bajo estos criterios y sugiere que, al hacerlo, se desprende que el Idealismo Trascendental no puede ser clasificado como una postura idealista que niegue la existencia de objetos o propiedades extramentales. Este análisis aporta una comprensión más profunda del alcance y (...) las implicaciones del Idealismo Trascendental de Kant en el contexto de la filosofía de la percepción, contribuyendo así al debate académico sobre la naturaleza del conocimiento y la realidad.

Coping with assessment tests are known to generate anxiety frequently in the students who face them. In academic circumstances with the continued presence of emotional disturbance, high demand, and stress, emotional and physical fatigue, typical of burnout syndrome, and can be detected. Anxiety and burnout are related to each other and even more closely in high-stakes tests. One of these tests is the examination imposed in Spain for access to the university. The objective of this work is to analyze the (...) presence of anxiety and burnout and the relationship between them in students who face these tests, both during the confinement situation due to the COVID-19 pandemic and during the pandemic after the lockdown. For this purpose, we used a sample of 1,021 students with a mean age of 17.89. Of these, 866 were students who were taking the test, while the rest were university students who had passed it recently. Our results show high levels of anxiety and burnout in students who face the evaluation test during the COVID-19 pandemic, sustained over time and especially in comparison with students who had already taken the exam. The association between higher levels of anxiety and higher levels of burnout in the students who take these exams was also verified. These results link the relationship between these two variables more solidly and suggest the need to include address anxiety to reduce burnout levels in these students. The results are discussed with regard to prior evidence and their applications. (shrink)

Academic philosophy's lack of diversity is of concern because it results in a discipline that does not adequately reflect or address the experiences, concerns, and perspectives of many people outside of the dominant demographic. In this article, I examine some of the practical and psychological challenges of entering into dialogue with thinkers whose background knowledge, culture, life experiences, and/or methodologies generate philosophical thought that is radically different from one's own. I contend that in order to build a discipline that is (...) more genuinely dialogical, academic philosophers should embrace this challenging tension between incommensurable worlds of sense. Specifically, I consider how the philosophical practice of translating foreign concepts into terms that have meaning for us might be carried out in a way that preserves radical friction. I warn of the risk of projecting our ideas onto those whose worldviews are incompatible with our own, and I offer strategies for navigating this risk. (shrink)

El conjunto de tratados de agricultura que se elaboró en al-Andalus ha sido hasta ahora explotado como fuente para aspectos relacionados con la botánica y la historia de las técnicas agrícolas; sin embargo, se ha empleado poco para la obtención de información histórica, aspecto que hemos tratado de enfatizar en este trabajo. Con este objetivo, hemos intentado situar la eclosión de los libros de agricultura en su contexto histórico: el de la revolución económica y demográfica plenomedieval, uno de cuyos aspectos (...) más significativos fue la expansión agrícola impulsada por un estamento de terratenientes, muchos de ellos residentes en las ciudades, que puso en marcha una producción orientada básicamente al mercado. A este grupo social es al que creemos estaban destinados principalmente los libros geopónicos, pues tenía la necesidad y los recursos económicos e intelectuales para aprovecharlos, a diferencia de los pequeños propietarios y las comunidades gentilicias de campesinos que practicaban una agricultura destinada esencialmente al autoabastecimiento. Una vez que reconocemos los libros de agricultura como auténticos manuales de aquellos hacendados, se puede recuperar esa literatura como fuente histórica de primer orden con el fin de conocer el funcionamiento y la organización de ese tipo de propiedad fundiaria en esta fase de la historia de al-Andalus.

A ciência experimental se concentra de forma peculiar, embora não exclusiva, no exame dos componentes materiais presentes na natureza e em suas relações quantitativas. Esta abordagem tem sido extremamente bem-sucedida, mesmo que haja lacunas e perplexidades a serem superadas, que, por sinal, também fazem parte do modus operandi da investigação experimental. Entretanto, se esta investigação é necessária para compreender a totalidade da natureza, ela já não é suficiente, o que é também corroborado por um sentimento de incompletude presente nas teorias. (...) Assim, existem razões justificáveis para se investigar a presença de uma estrutura não conceptualizável apenas em termos quantitativos chamada Realidade Velada pelo físico Bernard d'Espagnat, que pode ser assimilada à composição transcendental clássica de ser e essência, desde que este último elemento da composição, a essência, seja equivalente à estrutura forma-matéria, ou estrutura hilemórfica (aqui, matéria deve ser assimilada à matéria prima). Ora, a existência de tal estrutura reposicionaria a filosofia da natureza como conhecimento complementar ao da ciência experimental no sentido de que ele daria uma contribuição metafísica qualitativa relevante à pesquisa do que está além do limiar essencialmente quantitativo, conquanto necessário, oferecido pelas ciências da natureza.

Resumen. A la Sociedad Cooperativa, se le distingue por ser una sociedad mercantil con ciertas particularidades a diferencia de los demás tipos de sociedades, tan es así que se rige por su legislación especial. En los últimos años en México, se ha detectado un incremento de sociedades cooperativas dedicadas al suministro de personal, toda vez que el esquema fue considerado por algunos especialistas fiscales como una alternativa para las empresas que buscan disminuir sus cargas impositivas derivadas de las relaciones laborales. (...) Dicho esquema básicamente consiste en transferir a los trabajadores de las empresas a la sociedad cooperativa, los cuales al ser registrados como socios, las remuneraciones que estos perciben son bajo el concepto de previsión social; en lugar de salarios evitando así la retención y pago del Impuesto Sobre la Renta correspondiente. Con motivo de lo anterior, en la presente investigación se analizan y califican los aspectos más relevantes del asunto.Palabras claves. Sociedad cooperativa, evasión fiscal, outsourcing, previsión social.. A cooperative society is distinguished as a corporation with certain features unlike other types of companies, so much so that is governed by a special legislation. In recent years Mexico has seen an increase of cooperative societies dedicated to supply services, since the scheme was considered by some experts as an alternative tax for companies seeking to lower their tax burdens resulting from relations. This scheme basically consists of transferring workers from companies to the cooperative, which when registered as members the remuneration that they perceive are under the concept of social welfare, instead of avoiding wage withholding and payment of VAT Income for. On the occasion of the above, this research analyzes and scored the most relevant aspects of the case. (shrink)

Since the 1980s, there has been a significant increase in the number of studies concerning Andalusian rural settlements linked to irrigated agriculture, both related to large suburban green belts and to small hydraulic systems. In the vast areas where water is scarce, the settlement apparently would have been concentrated in cities and fortified towns, leaving without population most of the dry lands between them. However, thanks to the intensive survey of one of these regions, La Mancha’s Southeastern area, we are (...) recording a dense rural settlement corresponding to a pattern unknown until now. It consists basically of small villages in plain, devoid of community defense elements, which must have been inhabited by humble peasants, judging by the modesty of the architecture and domestic goods. Surely they make use of the scanty natural resources, which have traditionally oriented the economy of the region towards livestock and rainfed agriculture. In particular, the studied settlement would be related to the demand of wool for the export oriented textile production of the region, within the framework of the commercial expansion of that period. Apparently, most of those villages could have appeared in the eleventh century, disappearing in the middle of the thirteenth century because of the Christian conquest. Their existence would be associated with a general context of population growth that pushed the competition between urban elites and peasants pursuing the privileged agricultural areas, as well as the colonization of less favorable production areas.

Resumen: La imposibilidad del desarrollo para conciliar normativamente imparcialidad con pluralidad responde a un sesgo de carácter ontológico. Esta ruptura, que constituye la esencia misma de los estudios del desarrollo, supone aceptar que cualquier teoría del desarrollo que se precie se encuentra sustancialmente inacabada. De tal imposibilidad emerge, sin embargo, un perfeccionamiento que transcurre dialécticamente en términos de doble negación hegeliana por el cual las distintas teorías van perfeccionándose a partir de un mayor grado de concienciación normativa. Este perfeccionamiento alcanza (...) analíticamente un estado absoluto de desarrollo definido como libertad. Un concepto que perfecciona el presentado por Amartya Sen, facultado para reconciliar analíticamente el sesgo originario.: The impossibility of development to gather normatively impartiality and plurality makes itself to be ontologically incomplete. Nevertheless, the analytical that emerges in the very essence of development discipline implies to accept that any development theory is and will always be unfulfilled. Nevertheless, and beyond that substantive impossibility, an improvement occurs dialectically in terms of Hegelian double negation by which each theory is overcome by a higher grade of normative awareness by the following one. This improvement reaches analytically an absolute dimension of development as freedom. A concept that goes beyond such introduced by Amartya Sen, which it is well able of including all human determinations that ultimately allow to meet analytically those edges of the gap. (shrink)

In this paper I take Rorty’s self-description as a “hedgehog” as the starting point for a portrait of his intellectual temperament. I re-examine in the first instance Isaiah Berlin’s contrast between hedgehogs and foxes as inspired by the proverb of Archilocus. I then analyze, in philosophical terms, some differences between foxes and hedgehogs. I distinguish different types of hedgehogs in order to make clear exactly what kind of hedgehog Rorty was. In spite of his multiple interests and conversations, I argue, (...) Rorty portrayed himself as a hedgehog with only one important idea: the need to overcome notions such as Truth and Reason and to promote a less cruel and more anti-authoritarian way of living. I claim that this single idea is better understood when we pay special attention as to why Rorty gave priority to literature over philosophy, why he made distinctions between different types of writers, and why one of his favorite writers, Nabokov, was only apparently a fox.

Nineteenth-century investigations of the deep sea provide a case study for black box science. Naturalists were forced to theorize about a space for which they had no direct sensory observations. This study traces the emergence of bathymetry and deep-sea biology and then analyzes how men of science dealt with the uncertainty associated with their black box practices. I argue that these investigators created multiple types of black boxes based on their uncertainties and that these black boxes did not operate equivalently. (...) Consequently, scholars should be aware of the different categories of black boxes when they describe scientific practices. (shrink)
