Tristemente, la tecnología que en su día pareció suponer una gran ayuda para la prensa ha estado casi a punto de aniquilarla. (shrink)

Tras un análisis de las modificaciones que se producen en los textos de Descartes a propósito de las ideas innatas, de una primera visión que las considera contenidos innatos en la mente a otra que considera innata la facultad de pensar y. así, a todas las ideas por ella formadas, se señala que esta modificación está unida a un abandono de la identificación idea-imagen, y se sugiere que esta transformación sólo es explicable desde la problemática suscitada por la fundamentación de (...) la nueva Física.

Ship-type identification in a maritime context can be critical to the authorities to control the activities being carried out. Although Automatic Identification Systems has been mandatory for certain vessels, if a vessel does not have them voluntarily or not, it can lead to a whole set of problems, which is why the use of tracking alternatives such as radar is fully complementary for a vessel monitoring systems. However, radars provide positions, but not what they are detecting. Having systems capable of (...) adding categorical information to radar detections of vessels makes it possible to increase control of the activities being carried out, improve safety in maritime traffic, and optimize on-site inspection resources on the part of the authorities. This paper addresses the binary classification problem (fishing ships versus all other vessels) using unbalanced data from real vessel trajectories. It is performed from a deep learning approach comparing two of the main trends, Convolutional Neural Networks and Long Short-Term Memory. In this paper, it is proposed the weighted cross-entropy methodology and compared with classical data balancing strategies. Both networks show high performance when applying weighted cross-entropy compared with the classical machine learning approaches and classical balancing techniques. This work is shown to be a novel approach to the international problem of identifying fishing ships without context. (shrink)

We argue that it is fundamentally impossible to recover information about quantum superpositions when a quantum system has interacted with a sufficiently large number of degrees of freedom of the environment. This is due to the fact that gravity imposes fundamental limitations on how accurate measurements can be. This leads to the notion of undecidability: there is no way to tell, due to fundamental limitations, if a quantum system evolved unitarily or suffered wavefunction collapse. This in turn provides a solution (...) to the problem of outcomes in quantum measurement by providing a sharp criterion for defining when an event has taken place. We analyze in detail in examples two situations in which in principle one could recover information about quantum coherence: (a) “revivals” of coherence in the interaction of a system with the measurement apparatus and the environment and (b) the measurement of global observables of the system plus apparatus plus environment. We show in the examples that the fundamental limitations due to gravity and quantum mechanics in measurement prevent both revivals from occurring and the measurement of global observables. It can therefore be argued that the emerging picture provides a complete resolution to the measurement problem in quantum mechanics. (shrink)

Does the board of directors influence cost of debt financing? This study of a sample of Spanish listed companies during the period 2004-2007 provides some evidence about the question. The results suggest that two board attributes - director ownership and board activity - appear to influence in the risk assessment of debtholders because of their ability to reduce agency cost and information asymmetry. We also find a non-linear relationship between board size and cost of debt, suggesting that from certain levels (...) the benefits of large boards may be outweighed by the cost of poorer communication and increased decision-making time.

O artigo em questão trata do conceito de “escrita-currículo”, produzido no âmbito da perspectiva cultural de Educação Física. A partir da “pedagogia do conceito” inscrita na perspectiva filosófica de Félix Guattari e Gilles Deleuze, analisamos o referido conceito tomando como referência os elementos de: assinatura, historicidade, campo de imanência, elementos e componentes, multiplicidade, personagem conceitual, traços de intensidade e objetividade. Assim, vimos que o conceito procura movimentar de uma outra forma as práticas pedagógicas prescritas, fixas, rígidas, tradicionais, tecnicistas, procedimentais, acríticas, (...) homogeneizantes, moralizantes, deterministas e sequenciais.

I argue that the opening line of the _Phaedrus_ proleptically encapsulates the major themes of the dialogue and that paying attention to the opening line enables us to strengthen the identification of psychagogy as the key unifying thread of the whole dialogue. In particular, I argue that the opening line foreshadows the quarrel between Lysias and Socrates over the practical guidance of Phaedrus’ soul; the prominence of friendship in the philosophical form of life; the pertinence of Socrates’ one-on-one, custom-built speeches, (...) vis-à-vis the later conceptualization of rhetoric; the definition of the soul as a source of never-ending movement; as well as the origin (_arché_) and destiny (_télos_) of human souls, following the lines of the Palinode.

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

Este artigo compara e contrasta dois conceitos filosóficos provenientes de distintas linhagens de pensamento: de um lado, o _clinamen _de Lucrécio; do outro, o _conatus _de Espinosa. O que fomentou minha pesquisa foi uma conjugação dessas noções tal como proposto por Deleuze no apêndice de seu _Logique du sens_. Nesse sentido, a primeira seção está orientada tendo em vista uma elucidação da filosofia de Lucrécio — consequentemente, também a de Epicuro — e, especificamente, uma interpretação do desvio dos átomos ou (...) _clinamen_ em combinação com o tópico da liberdade. A segunda seção se dedica a clarificar a metafísica de Espinosa e a acomodação do tema da liberdade dentro de seu robusto enquadramento necessitário, entrelaçado com o motivo do _conatus _ou esforço de auto-preservação. Contra a leiture de Deleuze, entretanto, argumentarei que _clinamen _e _conatus _pertencem à sistemas metafísicos que são praticamente incompatíveis e que corroboram um entendimento diferente sobre liberdade e necessidade.

La finalidad de este artículo es explicar, mediante algunos testimonios significativos, de qué manera penetra en España el aristotelismo y cómo esta penetración del nuevo pensamiento aristotélico en Europa pone de manifiesto un permanente conflicto entre Edad Media y Renacimiento, fundamentalmente en España, donde el redescubrimiento y uso de las autoridades antiguas constituye a menudo un importante problema teórico. El autor muestra alguna de estas dificultades en varios dominios (filosofía, ciencia, literatura).

Este artículo estudia la hipotética penetración del islamismo –vertiente degradada del Islam- en algunos sectores de la extrema izquierda en Latinoamérica y reflexiona sobre su habilidad para desarrollar tanto una teoría como una práctica islamizadas de la revolución. El objetivo de esto es indagar en un aspecto inusual de la seguridad, el factor ideológico, habitualmente soslayado por preferirse los elementos estratégicos y tácticos. Para ello primero se investigan someramente algunos cambios del terrorismo ligados al islamismo en Latinoamérica. Después se analiza (...) la doctrina mediante la que el islamismo puede conectar con la extrema izquierda mediante los conceptos de revolución, guerra revolucionaria, guerra asimétrica y yihad. Finalmente están las conclusiones del artículo. (shrink)

This paper analyzes the concept of alterity in the thought of Emmanuel Levinas and its importance to make a critic of the ethical ones of dialogical inspiration. As opposed to the conception of the intersubjective relations founded on in a previous community, the alterity concept shows the necessity to think the sense to us of the ethics from the other.

Physical education is often selected for applying multilingual initiatives through the use of the content and language integrated learning (CLIL) approach. However, it is still unclear whether the introduction of such approach might entail losing Physical Education’s essence and distorting its basic purposes. The aim of this study is to analyse the impact of CLIL on the Physical Education lessons. Given the purpose of this study, a mixed methodological approach based on a sequential exploratory design divided in two different phases (...) is used. We begin with an initial qualitative data collection (phase I) consisting in the analysis of interviews with 12 participants (8 teachers and 4 students). Based on its analysis, two foci are identified: social relationships and physical activity. Then, informed by the results obtained, a quantitative approach is used (phase II), differentiating these two sets of data to deepen on them. On one part, a sociometric questionnaire was applied to analyse the social relationships among CLIL students. On the other part, a quasi-experimental design (n = 49) was implemented using accelerometry to measure the MVPA of the PE sessions. Regarding physical activity, the results show that levels of MVPA are higher in the experimental group (CLIL) than in the control group showing light to the divergent viewpoints of interviewees. However, focusing on social relationships, the sociometric questionnaire results show that there were no statistical significative changes, although some signs of a slight effect on students’ relationships arise depending on their gender. Therefore, more research would be necessary to deepen on how CLIL affects in this regard. (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...

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.

Background: Heart rate variability (HRV) has been considered as a measure of heart-brain interaction and autonomic modulation, and it is modified by cognitive and attentional tasks. In cognitive tasks, HRV was reduced in participants who achieved worse results. This could indicate the possibility of HRV predicting cognitive performance, but this association is still unclear in a high cognitive load sport such as chess Objective: To analyse modifications on HRV and subjective perception of stress, difficulty and complexity in different chess problem (...) tasks. Design: HRV was assessed at baseline. During the chess problems, HRV was also monitored, and immediately after chess problems the subjective stress, difficulty and complexity were also registered. Method: A total of 16 male chess players, age: 35.19 (13.44) and ELO: 1927.69 (167.78) were analysed while six chess problem solving tasks with different level of difficulty were conducted (two low level, two medium level and two high level chess problems). Participants were classified according to their results into two groups: high performance or low performance. Results: Friedman test showed a significant effect of tasks in HRV indexes and perceived difficulty, stress and complexity in both high and low performance groups. A decrease in HRV was observed in both groups when chess problems difficulty increased. In addition, HRV was significantly higher in the high performance group than in the low performance group during chess problems. Conclusions: An increase in autonomic modulation was observed to meet the cognitive demands of the problems, being higher while the difficulty of the tasks increased. Non-linear HRV indexes seem to be more reactive to tasks difficulty, being an interesting and useful tool in chess training. (shrink)
