The price of copper is unstable but it is considered an important indicator of the global economy. Changes in the price of copper point to higher global growth or an impending recession. In this work, the forecasting of the spot prices of copper from the New York Commodity Exchange is studied using a machine learning method, support vector regression coupled with different model schemas (recursive, direct and hybrid multi-step). Using these techniques, three different time series analyses are built and its (...) performance are compared. The numerical results show that the hybrid direct-recursive obtains the best results.

Nieto Arteta, it examines the reception of Marxism, phenomenology, philosophy of law, economic and social history and innovations in the fields of civil and criminal law.

ObjectivesThe aims of this research were to compare the levels of physical activity of eHealth users and non-users, to determine the effects of these technologies on motivations, and to establish the relationship that could exist between psychological constructs and physical activity behaviors.MethodsThis cross-sectional study involved 569 adults who responded to an online questionnaire during confinement in France. The questions assessed demographics, usage of eHealth for exercise and physical activity, and behavioral levels. The questionnaire also measured the constructs of Social Cognitive (...) Theory, the Theory of Planned Behavior, and automaticity facets toward eHealth for exercise and physical activity.ResultsParticipants who were users of eHealth for exercise and physical activity presented significantly higher levels of vigorous physical activity and total physical activity per week than non-users. The chi-square test showed significant interactions between psychological constructs toward eHealth and physical activity levels. Self-efficacy was significantly and negatively correlated with walking time per week. Concerning the automaticity facets, efficiency was positive and significantly correlated with vigorous physical activity levels per week. Then, regressions analyses showed that self-efficacy and automaticity efficiency explained 5% of the variance of walking minutes per week and vigorous physical activity per week, respectively.ConclusionThis study has shown that people during confinement looked for ways to stay active through eHealth. However, we must put any technological solution into perspective. The eHealth offers possibilities to stay active, however its benefits and the psychological mechanisms affected by it remains to be demonstrated: eHealth could be adapted to each person and context.

El sistema filosófico de Spinoza no puede ser considerado en rigor como panteísta, sino panenteísta. Este artículo intenta reforzar esta tesis analizando los conceptos de Natura naturans y Natura naturata, a veces confundidos en la obra de Spinoza. Se establece además una comparación de ambos conceptos en Spinoza y en David Nieto, autor de una obra titulada De la divina providencia, o sea naturaleza universal o natura naturante, al tiempo que se señalan las diferencias entre las concepciones inmanentes de (...) la divinidad de ambos autores.

El presente trabajo propone determinadas aproximaciones iusfilosóficas al discurso jurídico, a partir de los estudios realizados por Walter Benjamin sobre Franz Kafka. La investigación se realiza con las herramientas metodológicas que aportan las “teorías críticas del derecho” y los marcos teóricos que indagan la relación “derecho-literatura”. Los textos, discusiones y apuntes realizados por el pensador alemán permiten movilizar un análisis de determinados tópicos y categorías pertenecientes al espacio jurídico. Las investigaciones que realiza en torno a la figura de Kafka ofrecen (...) insumos para indagar la formación, despliegue y conservación del derecho. Desde la obra kafkiana, Benjamin visibiliza y desarticula los conceptos nodales de justicia, ley, poder y violencia, lo que permite dar cuenta de los mecanismos y dispositivos que hacen posible el sustento mitológico del derecho.

Different theoretical models have proposed cognitive and affective components in empathy and moral judgments encompassing compassion. Furthermore, gender differences in psychological and neural functions involving empathic and moral processing, as well as compassionate experiences, have been reported. However, the neurobiological function regarding affective and cognitive integration underlying compassion and gender-associated differences has not been investigated. In this study, we aimed to examine the interaction between cognitive and emotional components through functional connectivity analyzes and to explore gender differences for the recruitment (...) and interaction of these components. Thirty-six healthy participants were exposed to social images in an fMRI session to judge whether the stimuli elicited compassion. The results showed a different connectivity pattern for women and men of the insular cortex, the dorsomedial prefrontal cortex, the orbitofrontal cortex, and the cingulate cortex. The integration of affective and cognitive components follows a complex functional connectivity pattern that is different for both genders. These differences may indicate that men largely make compassionate judgments based on contextual information, while women tend to notably take internal and introspective processes into account. Women and men can use different affective and cognitive routes that could converge in similar learning of moral values, empathic experiences and compassionate acts. (shrink)

A lo largo de este artículo se va a tratar de analizar la concepción del Romanticismo propuesta por Flaubert. En ella, a raíz del viaje a Oriente entre 1849 y 1851, se produce un cambio que hace constituir a la tarea del literato, artista o filósofo romántico en una tarea en la que la cuestión fundamental de la Estética y del Arte debe mezclarse con la tarea Ética y de pensamiento de la Política para la sociedad del futuro.  .

Wind turbines have been used by many groups of humans for many centuries. Wind turbines have allowed groups of humans to perform many different tasks in the past. However, only a century and a half ago, they began to be used to convert the energy captured from wind into electric energy. Moreover, only approximately twenty-five years ago, we started to introduce on a massive scale the energy generated from wind turbines into the electric networks of most developed countries in the (...) world for regular consumption. According to 2017 statistics, approximately 12 percent of the electric energy consumed in the EU is produced by wind turbines. Despite the fact that wind turbines generally appear quite similar externally—i.e., a three-blade structure, a nacelle, a tower, etc.—if we carefully examine the electric technology used within them, we find quite a wide range of technologies for energy conversion, which is a key issue in wind turbine technology. Hence, this paper adopts a dialectic perspective towards analyzing and understanding why several electric technologies coexist in wind turbine technology. We explain the specific factors that have influenced different wind turbine manufacturers to adopt different electric technologies across the last twenty-five years. We show how their actions and the technological directions that have followed have been mutually codetermined, resulting in a technological evolution that has produced today’s wind turbine variety.

In this paper we contrast bounded and ecological rationality with a proposed alternative, generative rationality. Ecological approaches to rationality build on the idea of humans as “intuitive statisticians” while we argue for a more generative conception of humans as “probing organisms.” We first highlight how ecological rationality’s focus on cues and statistics is problematic for two reasons: the problem of cue salience, and the problem of cue uncertainty. We highlight these problems by revisiting the statistical and cue-based logic that underlies (...) ecological rationality, which originate from the misapplication of concepts in psychophysics. We then work through the most popular experimental task in the ecological rationality literature—the city size task—to illustrate how psychophysical assumptions have informally been linked to ecological rationality. After highlighting these problems, we contrast ecological rationality with a proposed alternative, generative rationality. Generative rationality builds on biology—in contrast to ecological rationality’s focus on statistics. We argue that in uncertain environments cues are rarely given or available for statistical processing. Therefore we focus on the psychogenesis of awareness rather than psychophysics of cues. For any agent or organism, environments “teem” with indefinite cues, meanings and potential objects, the salience or relevance of which is scarcely obvious based on their statistical or physical properties. We focus on organism-specificity and the organism-directed probing that shapes awareness and perception. Cues in teeming environments are noticed when they serve as cues-for-something, requiring what might be called a “cue-to-clue” transformation. In this sense, awareness toward a cue or cues is actively “grown.” We thus argue that perception might more productively be seen as the presentation of cues and objects rather than their representation. This generative approach not only applies to relatively mundane organism interactions with their environments—as well as organism-object relationships and their embodied nature—but also has significant implications for understanding the emergence of novelty in economic settings. We conclude with a discussion of how our arguments link with—but modify—Herbert Simon’s popular “scissors” metaphor, as it applies to bounded rationality and its implications for decision making in uncertain, teeming environments.

Partimos de unas reflexiones sobre el Racionalismo y el Historicismo como dos enfoques con perfiles epistemológicos claramente diferenciados, que llevan a quien en ellos se sitúe a muy diversos planteamientos respecto a cualquier cuestión de carácter social. Examinamos el alcance y potencial de ambos en su argumentación cuando pretenden dar cuenta del origen de la sociedad política y todo lo que ello representa, instituciones, valores… Esbozada esta cuestión se recala en el análisis jovellanista de la mujer. Jovellanos conoce bien ambos (...) enfoques, sus lecturas de los autores aquí citados están plenamente contrastadas y no son objeto de este trabajo; apuesta por el enfoque historicista inglés para comprender el rol femenino, para situar a las instituciones que le niegan su ingreso en su decurso histórico, y curiosamente convierte el modelo historicista en una vía de análisis y acceso a propuestas de una extraordinaria modernidad. Analizamos desde estos enfoques los planes de estudio en los que estamos inmersos. (shrink)

Differences in Common engages in the ongoing debate on ‘community’ focusing on its philosophical and political aspects through a gendered perspective. It explores the subversive and enriching potential of the concept of community, as seen from the perspective of heterogeneity and distance, and not from homogeneity and fused adhesions. This theoretical reflection is, in most of the essays included here, based on the analysis of literary and filmic texts, which, due to their irreducible singularity, teach us to think without being (...) tied, or needing to resort, to commonplaces. Philosophers such as Arendt, Blanchot, Foucault, Agamben or Derrida have made seminal reflections on community, often inspired by contemporary historical events and sometimes questioning the term itself. More recently, thinkers like Judith Butler, Gayatri Spivak or Rada Ivekovic—included in this volume are essays by all three—have emphasized the gender bias in the debate, also problematizing the notion of community. Most of the essays gathered in Differences in Common conceive community not as the affirmation of several properties which would unite us to other similar individuals, but as the “expropriation” of ourselves (Esposito), in an intimate diaspora. Community does not fill the gap between subjects but places itself in this gap or void. This conception stresses the subject’s vulnerability, a topic which is also central to this volume. The body of community is thus opened by a “wound” (Cixous) which exposes us to the contagion of otherness. The essays collected here reflect on different topics related to these issues, such as: gender and nation; nationalism, internationalism, transnationalism; nationalism’s naturalization of citizenship and the exclusion of women from citizenship; the violent consequences of a gendered nation on women’s bodies; gendering community; preservation of difference(s) within the community; bodily vulnerability and new politics; community and mourning; community and the politics of memory; fiction, historical truth and (fake) documentary; love, relationality and community; interpretive communities and virtual communities on the Web, among others.

Debido a sus aportaciones, Lutero representaría un personaje clave para entender el inicio de la modernidad, aunque las líneas religiosas de su pensamiento no corresponden con los principios de este movimiento, ya que su propuesta sometía toda facultad humana a la fe, rechazando la razón como principio rector de la voluntad. No obstante, en su alzamiento, el agustino no se percató de lo racional que fue su proceder a través de las acciones tomadas para impulsar su reforma, dejando ver que, (...) por encima de lo religioso, las iniciativas de Lutero, representan una búsqueda de alternativas expresadas racionalmente.

Ethical banking, microfinance institutions or certain credit cooperatives, among others, grant socially responsible loans. This paper presents a credit score system for them. The model evaluates social and financial aspects of the borrower. The financial aspects are evaluated under the conventional banking framework, by analysing accounting statements and financial projections. The social aspects try to quantify the loan impact on the achievement of Millennium Development Goals such as employment, education, environment, health or community impact. The social credit score model should (...) incorporate the lender’s know-how and should also be coherent with its mission. This is done using Multi-Criteria Decision Making. The paper illustrates a real case: a loan application by a social entrepreneur presented to a socially responsible lender. The decision support system not only produces a score, but also reveals strengths and weaknesses of the application. (shrink)

Based on experience in marriage counseling and contributions made by philosophy of phenomenology and psychology, we have carried out an in-depth analysis of the forgiveness process in the marriage relationship. Philosophy of phenomenology allows to define the conceptual framework of the marriage relationship and its essential features, which gives the therapist a reference to guide the therapeutical process. The description of the process is enriched with contributions of Psychology and particularly Systemic Family Theories. We have identified a number of steps (...) in the forgiveness process, which can be summarized as the passing from the initial pain, through the recovery of dignity and hope, up to the final consciousness of having reached forgiveness, where the intrapersonal process in the offended spouse is imbricated with the interpersonal relationship with the partner in marriage. This interdisciplinary perspective, bringing together clinical practice, philosophy of phenomenology, and psychology, has proven particularly fruitful: it has allowed us to identify when forgiveness becomes a case of regeneration and strengthening of the bonds of marriage, or on the contrary, the cases in which the problems, together with situations of imbalance or relational pathology progress to a chronic state. Apart from this, we have reflected upon the practical application of this theoretical approach in a therapeutic context with couples that need to pass through the forgiveness process, paying special attention to the risks they may encounter. Finally, we suggest possibilities for further investigations along these interdisciplinary lines of study. (shrink)

¿Qué es una crisis epistemológica? La descripción que hace Descartes de su propia crisis epistemológica tuvo, ciertamente, una influencia única, y esto a pesar de que describe de modo radicalmente erróneo su propia crisis, y ciertamente ha mostrado ser una guía altamente errónea sobre la naturaleza de las crisis epistemológicas en general.

Published in 1998, the main aim of this book is to use a naturalistic, evolutionary approach to solve some of the most important problems in philosophy. The first two problems come from the philosophy of science: the problem of rationality of science and the problem of truth in science. In presenting the first problem, the author argues that the views of Kuhn and Feyerabend do create a very serious challenge to traditional epistemology, however, if the assumption of individual rationality is (...) abandoned in favour of the author's social concept of rationality, a committed naturalism can account for science as a rational activity. In tackling the second problem of truth, the author shows that a committed evolutionary philosophy does not support realism but leads instead to a thorough evolutionary relativism of scientific knowledge. It is nevertheless possible to use this evolutionary relativism to construct a theory of relative truth. The issue of whether science discovers truth has also been tied to absolutism, that a well formulated theory of relative truth is likely to bring about a profound transformation of the way we think about the field. The author explores the notion of relative truth in the philosophy of science, ethics and aesthetics. (shrink)

This article analyzes the evolution of Philosophy of Educationin Spain and its situation at the dawn of the 21st century. Spain'speculiar socio-historical circumstances have largely conditioned thedirection this discipline has taken over the last several decades. So,although during a period there was some approximation towards themethods of analytic philosophy, Philosophy of Education has never fullyrelinquished its normative vocation. To do so would have meant spurningthe hopes and fears that had filled Spanish society by the mid 1970supon the reinstatement of civil (...) liberties and democracy. Indeed,attention to the circumstances and that normative orientation have foundtheir best fit in a practical Aristotelian-based philosophy meant toendow Philosophy of Education with a normative character that do notshun the educator's need for reflection, practical decision-making, andresponsibility. Since the 1990s, new directions have been marked by thechallenge of postmodernism, inasmuch as it affects not only thetechnological positivist model but also the reflective educator's modelof a practical Philosophy of Education. The new directions spread out invarious ways, yet they all fall into a common denominator of narrativetrends. The problem posed by these new languages lies in the extent towhich they are consistent with pedagogic intent. In turn, the answerstake on different profiles depending on whether the stance leans moretowards the philosophical or the pedagogical point of view withinPhilosophy of Education. The complementary nature of both perspectivescharacterizes the current state of the field in Spain. (shrink)

Talk ofeducation as a human right presupposes taking part in a horizon ofinterpretation. Projected is a view of person as a subject, i.e., assomeone not only placed in a specific context, but also as someone whois capable of distancing him/herself from (...) local and culturalconditioning.

En el presente trabajo se pretende llevar a cabo una aproximación al fenómeno del colapso ecológico y su relación con la filosofía de la historia a través de las aportaciones de Walter Benjamin y Theodor Adorno. En este sentido, el fenómeno del colapso ecológico será abordado como la barbarie de nuestro tiempo, introduciéndonos en uno de los conceptos con mayor recorrido en la teoría crítica, para acto seguido explorar diversas vías filosóficas abiertas para hacerle frente en la actualidad.

In this study, we propose considering membership in the Ethics Officer Association (EOA) as a proxy for the firm's commitment to ethical decision making, and we analyze the influence of firm- and CEO-specific characteristics on this commitment. While we observe a positive relationship between membership and firm size, we also document a negative relationship between EOA membership and the executive's time in position and, to a more modest extent, accounting returns. Pursuing this further, we present evidence that firms with past (...) legal issues may seek EOA membership as a signal of their intention to be compliant in the future. (shrink)
