The purpose of this paper is to present several applications of combinatorial principles, well-known in Set Theory, to the geometry of infinite dimensional Banach spaces, particularly to the existence of certain basic sequences. We mention also some open problems where set-theoretical techniques are relevant.

En el presente estudio se abordarán los crímenes cometidos por mujeres durante los últimos años de la España de la Restauración y la Dictadura de Primo de Rivera. De igual modo, se profundizará en la dicotomía espacial y discursiva que suponen estas acciones al ser cometidas en el ámbito de lo privado, pero pronto extrapoladas a lo público con fines sen­sacionalistas. Recortes de prensa, fragmentos literarios y pun­tualmente sentencias judiciales serán las fuentes de las que nos valdremos para desarrollar esta (...) investigación con el objeto de profundizar en esta difusa línea divisoria de actuación dialécti­ca. Contra los preceptos definidos por el discurso dominante en torno al «sexo femenino» que encasillaba a las mujeres en una concepción de perpetua debilidad, belleza y letargo, la trans­gresión nacida en el seno de lo privado se hará pública demos­trando que las idealizaciones creadas sobre ellas poco tenían que ver con la realidad.

The acquisition and evolution of speech production, discourse and communication can be negatively impacted by brain malformations. We describe, for the first time, a case of developmental dynamic dysphasia (DDD) in a right-handed adolescent boy (subject D) with cortical malformations involving language-eloquent regions (inferior frontal gyrus) in both the left and the right hemispheres. Language evaluation revealed a markedly reduced verbal output affecting phonemic and semantic fluency, phrase and sentence generation and verbal communication in everyday life. Auditory comprehension, repetition, naming, (...) reading and spelling were relatively preserved, but executive function was impaired. Multimodal neuroimaging showed a malformed cerebral cortex with atypical configuration and placement of white matter tracts bilaterally and abnormal callosal fibers. Dichotic listening showed right hemisphere dominance for language and functional magnetic resonance imaging (fMRI) additionally revealed dissociated hemispheric language representation with right frontal activation for phonology and bilateral dominance for semantic processing. Moreover, subject D also had congenital mirror movements (CMM), defined as involuntary movements of one side of the body that mirror intentional movements of the other side. Transcranial magnetic stimulation and fMRI during voluntary unimanual (left and right) hand movements showed bilateral motor cortex recruitment and tractography revealed a lack of decussation of bilateral corticospinal tracts. Genetic testing aimed to detect mutations that disrupt the development of commissural tracts correlating with CMM (e.g., Germline DCC mutations) was negative. Overall, our findings suggest that DDD in subject D resulted from the underdevelopment of the left inferior frontal gyrus with limited capacity for plastic reorganization by its homologous counterpart in the right hemisphere. Corpus callosum anomalies probably contributed to hinder interhemispheric connectivity necessary to compensate language and communication deficits after left frontal involvement. (shrink)

Chagas disease or American trypanosomiasis is an important health problem in Latin America. Due to the mobility of Latin American population around the world, countries without vector presence started to report disease cases. We developed a deterministic compartmental model in order to gain insights into the disease dynamics in a scenario without vector presence, considering congenital transmission and transmission by blood transfusion. The model was used to evaluate the epidemiological effect of control measures. It was applied to demographic data from (...) Spain and sensitivity analysis was performed on model parameters associated with control strategies. (shrink)

After the end of their time as a caregiver, former caregivers have needs and feelings that have been subject to little study to date. The aim of the study is to determine and analyse the feelings, perceptions and practices of former caregivers in the reconstruction of their daily lives. This is a qualitative study based on the Grounded Theory developed by Charmaz. The study involved 14 former caregivers who had cared for their relative for more than 2 years and who (...) had stopped caring for them more than 2 years previously. Fourteen in-depth interviews were conducted and data were collected over 13 months between 2015 and 2017. Data were analysed using the Grounded Theory Method. In addition, this study was approved by the ethics committee of the Institut Universitari d’Investigació en Atenció Primària Jordi Gol. The former caregiver experiences a transition, which begins in the days before the death of their relative and may continue for more than 3 years. Three critical moments in the post-caring transition were found: the post-caring emptiness; the end of the period as a caregiver; and the movement towards a new life. Family and professional support is needed during this transition. Former caregivers experience a transition in the rebuilding of their daily lives; furthermore, former caregivers may be a source of support for other caregivers, which is linked to positive mental health factors. Healthcare organisations need to acknowledge the emotional, psychosocial and psychological health of former caregivers. (shrink)

Our memories elicit, in us, both beliefs about what the external world was like in the past, and beliefs about what our own past experience of it was like in the past. What explains the power of memories to do that? I tackle this question by offering an account of the content of our memories. According to this account, our memories are ‘token-reflexives’, in that they represent their own causal origin. My main contention will be that our memories are able (...) to provide us with evidence for the two types of beliefs due to the self-referential nature of their content. First, I will put forward a series of thought-experiments intended to raise several intuitions about the veridicality of memories. Next, I will introduce the view that memories are token-reflexives, and I will motivate it by pointing out that the view accommodates the relevant intuitions. And, then, I will return to the two types of beliefs prompted by our memories, and argue that conceiving memories as token-reflexives allows us to explain why memory has the power to elicit the two types of beliefs in us.

Memories are mental states with a number of interesting features. One of those features seems to be their having an intentional object. After all, we commonly say that memories are about things, and that a subject represents the world in a certain way by virtue of remembering something. It is unclear, however, what sorts of entities constitute the intentional objects of memory. In particular, it is not clear whether those are mind-independent entities in the world or whether they are mental (...) entities of some kind. The purpose of this chapter is to map the different positions on this issue, and to highlight the virtues and difficulties for each of the options. In Section 2, I will specify the question of what the intentional objects of memory are by clarifying the relevant notions of memory and intentional object. In Section 3, I will motivate the significance of identifying the intentional objects of memory by exploring the relations between, on the one hand, the intentionality of memory and, on the other hand, the phenomenology and the epistemology of memory. In Section 4, I will consider two natural candidates for being the intentional objects of memory, namely, worldly entities and mental entities, and I will raise some concerns for each of the two candidates. A promising alternative will emerge, in Section 5, as preserving the virtues of the two original candidates while avoiding their difficulties. The alternative will concern a certain combination of worldly and mental entities; a combination that involves both causal and truth-making relations. I will conclude by sketching how the alternative candidate can shed some light on the phenomenological and epistemological issues raised in the third section. (shrink)

In Lukács: Praxis and the Absolute, Daniel Andrés López reassembles Lukács’s philosophy of praxis on a Hegelian basis, as a conceptual-historical totality, both defending him and proposing an unprecedented, immanent critique that raises problems for Marxian philosophy as a whole.

In most domains of human life, we are willing to accept that there are experts with greater knowledge and competencies that distinguish them from non-experts or laypeople. Despite this fact, the very recognition of expertise curiously becomes more controversial in the case of “moral experts”. Do moral experts exist? And, if they indeed do, are there ethical reasons for us to follow their advice? Likewise, can emerging technological developments broaden our very concept of moral expertise? In this article, we begin (...) by arguing that the objections that have tried to deny the existence (and convenience) of moral expertise are unsatisfactory. After that, we show that people have ethical reasons to ask for a piece of moral advice in daily life situations. Then, we argue that some Artificial Intelligence (AI) systems can play an increasing role in human morality by becoming moral experts. Some AI-based moral assistants can qualify as artificial moral experts and we would have good ethical reasons to use them. (shrink)

Shows the relevance of Schiller’s thought for contemporary philosophy, particularly aesthetics, ethics, and politics. This book seeks to draw attention to Friedrich Schiller (1759–1805) as a philosophical thinker in his own right. For too long, his philosophical contribution has been neglected in favor of his much-deserved reputation as a political playwright. The essays in this collection make two arguments. First, Schiller presents a robust philosophical program that can be favorably compared to those of his age, including Rousseau, Kant, Schelling, and (...) Hegel, and he proves to be their equal in his thinking on morality, aesthetics, and politics. Second, Schiller can also guide us in our more contemporary philosophical concerns and approaches, such as phenomenology, hermeneutics, aesthetics, and politics. Here, Schiller instructs us in our engagement with figures such as Walter Benjamin, Michel Foucault, Jacques Rancière, Roberto Esposito, and others. María del Rosario Acosta López is Associate Professor of Philosophy at DePaul University. She has published several books, including La tragedia como conjuro: el problema de lo sublime en Friedrich Schiller. Jeffrey L.

El debate en torno a la antropología aborda aquí una cuestión de categorías fundamentales en torno a la estructura básica del ser humano: hombre y mujer, niño y anciano. La terminología articulada por la categoría «espíritu - pneuma» abre las posibilidades de una nueva comprensión ante los retos planteados por las ciencias experimentales, la ética, la moral, incluso la religión. El esquema diádico «cuerpo y alma» se muestra agotado ante los callejones sin salida con los que se ha encontrado al (...) llegar hasta nuestros días. Por este motivo, el artículo defiende poder recuperar la antropología brotando de los datos de la revelación judeocristiana, tomados como auténticos y válidos para vehicular la verdad de la realidad humana. En efecto, resulta necesario recuperar la originalidad de la estructura triádica de espíritu, alma y cuerpo, presentada por el apóstol Pablo, de forma totalmente inesperada en su primera carta a los Tesalonicenses (1Te 5,23).

In recent discussions on contextualism and relativism, some have suggested that audience-sensitivity motivates a content relativist version of radical relativism, according to which a sentence as said at a context can have different contents with respect to the different perspectives from where it is assessed. The first aim of this note is to illustrate how this is not so. According to Egan himself, the phenomenon motivates at least refinement of the characteristic moderate contention that features of a single context determine (...) the appropriate truth-value of the sentence. The second aim of this note is to explore how this may not be so. (shrink)

When travelling to a new city, we acquire knowledge about its physical terrain, directions, historical facts and aesthetic features. Engaging in tourism practices, such as guided walking tours, provides experiences of a city that are necessarily mediated and partial. This has led scholars in tourism studies, and more recently in philosophy, to question the epistemological value of city tours, critiquingthem as passive, lacking in autonomous agency, and providing misrepresentative experiences of the city. In response, we argue that the mediated and (...) partial knowledge of a city acquired through city tours is not epistemologically disvaluable. Although city tours involve the transmission of testimonial knowledge, this does not necessarily render tourists as passive and non-autonomous. Instead,tourists have the potential to participate in the generation of their knowledge actively. Moreover, we argue that city tours also provide a tourist with valuable ‘objectual’ knowledge of a city, whichhas the potential to be first-personal and active, and does not necessarily misrepresent the city’s identity. This type of knowledge is valuable both for tourists as credible epistemic agents, and for the city itself, as the knowledge generated by the tour can facilitate an accurate representation of the city and promote social transformation. We conclude by highlighting four further epistemic and ethical implications of our argument. (shrink)

In procedural-law scholarship as well as in the theoretical analysis of the notion of proof as a result of the joint assessment of all items of evidence introduced in a trial, reference is frequently made to notions such as the conviction, belief, or certainty of a judge or a jury member about what happened. All these notions underscore the mental states involved in the process of determining the facts on the part of a judge or a jury. In this analysis, (...) I look at the links between beliefs and the justification in the findings of fact provided by the judge or jury in her or its verdict. (shrink)

In this introduction, I consider different problems posed by the use of singular terms in fiction (section 1), paying especial attention to proper names and, in particular, to names of real people, places, etc. As we will see (section 2), descriptivist and Millian theories of reference face different kinds of problems in explaining the use of fictional names in fiction-related contexts. Moreover, the task of advancing a uniform account of names in these contexts—an account which deals not only with fictional (...) names but also with “real” names—will prove to be very hard no matter whether we favour realist or antirealist intuitions about fictional discourse (section 3). Section 4 offers an overview of the content of this volume, with emphasis on the discussion between Manuel García-Carpintero and Stacie Friend about the meaning of “real” names in fiction-related contexts, the main topic of the Third Blasco Disputatio.

Social Education implies a constant exposition to human experiences of vulnerability and suffering. In this paper, Levinas’s philosophy of alterity and, specifically, the notion of hospitality constitutes our ethical lens to explore educational encounters in non-formal contexts within the Spanish Social Sector. The study is developed from a hermeneutic phenomenological approach into the depth of lived experiences of eight social educators who currently work with different populations groups. The testimonies, explored through semi-structured interviews, are presented in a conversational, dialogic, poetic (...) format. First, Levinas’ philosophy is presented as our ethical position, focusing on subjectivity as hospitality. Secondly, methodological aspects regarding hermeneutics are addressed. Finally, the testimonies of social educators are presented in an evocative way, exploring uncertainty and three different tensions regarding human relations in their practices: physical spaces, affection, and embodiment.

Critical studies in higher education often embrace the ideas of the slowness movement to address time pressure. However, this desirable horizon presents some limitations. On the one hand, by emphasizing solutions at the individual level, boosting slowness may promote tactics incapable of producing changes to the underlying structural dynamics of time pressure. On the other hand, approaches based on slowness may also inadvertently foster a form of ethical paternalism within the context of ethical pluralism by prescribing substantive models of practice (...) ultimately based on ‘do this quickly or do it slowly.’ This theoretical research moves away from the temporal paradigm to that of the way of relating. Building upon the ethical concept of resonance, the approach focuses on a formal critique of the current socioeconomic and ethical dynamics of social acceleration, growth, and innovation that can contribute to projecting non-alienated relationships in higher education.

In jurisprudential literature, the adjective ‘defeasible’ appears as a predicate of many terms: concepts, laws, rules, reasoning, justification, proof, and so on. In this paper, we analyze the effects of some versions of the thesis of the defeasibility of legal norms on the reconstruction of the notion of legal validity. We analyze some possible justifications of this thesis considered as a claim concerning validity, and enquire into two possible sets of problems related to the defeasibility of the criteria of identification (...) of a legal system. We also provide a formalization of some options regarding defeasible criteria of identification, which can be used as a tool for meta-jurisprudential analysis. Finally, the thesis according to which defeasibility is better conceived of as a feature of legal application is examined and questioned. (shrink)

Avicenna was a physician and philosopher in an era known as the Islamic Golden Age. His early medical encyclopedia, The Canon of Medicine, was a groundbreaking text that scholars and healers read for centuries afterward.

The conceptualization of the notion of subjectivity within the Anthropocene finds in Rosi Braidotti’s posthumanism one of its most explicit and profuse modulations. This essay argues that Braidotti’s model powerfully accounts for the Anthropocene’s subjectivity by conceiving the “self” as a transversal multiplicity and its relationality to the “others” and the “world” as non-hierarchized by nature–culture distinctions; however, by being ontologically grounded on a neo-Spinozistic monism, Braidotti’s model blurs the notions of finitude, agency, and change, obscuring the possibility of critical (...) dissent while decreasing the overall theory’s consistency. An alternative ontological model capitalizing on these elements can be found in Object-Oriented Ontology and its notion of withdrawal. By associating OOO’s non-onto-taxonomical pluralism with Braidotti’s posthuman subjectivity, this essay aims at ontologically discretizing the latter in order to overcome these limitations. Grounded on this association and invoking a narrative imaginary propelled by the Greek terms xenos and xenia, the article paves the way for a form of subjectivity deviating from Braidotti’s ecological model and defined as xenological, arguing that, within the context of the Anthropocene, it constitutes an adequate alternative to Braidotti’s subjectivity.

The ontological abyss that separates real objects from sensual objects is one of the central principles of Object-Oriented Ontology (OOO), which has its most explicit and profuse modulation in Timothy Morton’s notion of rift. This article argues that, despite succeeding in explaining the radical difference that inhabits every object, Morton’s rift fails to explain the object’s unification, rendering the overall theory inconsistent. An alternative approach that accounts simultaneously for disjunction and conjunction between essences and appearances can be found in Eugenio (...) Trías’s philosophy of the limit, a term widely ignored in OOO despite its deeply non-relational conception of the reality of things. The article further argues that the reinterpretation of Trías’s twofold liminal approach in light of OOO successfully addresses the inconsistencies found in Morton’s rift, paving the way for a theory of limits within Harman’s ontological framework.

Although most consumers are positive about socially responsible companies, in order to benefit from CSR efforts, effective and clear CSR communication is important. However, due to the constantly rising profusion of eco-labels, based on either own claims from the organization or claims made by an external third party, consumers may encounter difficulties in identifying truly responsible firms, which could result in less effective CSR initiatives, even for those responsible firms. Therefore, building on attribution theory, this study seeks to identify how (...) uncertified internal CSR claims and external third-party CSR labels should be used in order to deter greenwashing and increase positive consumer evaluations. Within a 3 × 2 design, respondents are exposed to different coffee product packages measuring their attitude toward the brand, corporate credibility, purchase intention, and scent perception, as well as perceived attributional CSR motives. Overall, findings indicate that especially an external CSR label affects consumer responses toward the firm. Moreover, perceived CSR motives serve as a mediator between an external CSR label and corporate credibility and brand attitude, respectively. These findings warrant further consideration of introducing an external multilevel rating systems by governmental law. (shrink)

Ante los indicadores de insostenibilidad ambiental y social, se busca un enfoque educativo eficaz que contribuya a revertirla. A tal efecto, se propone una educación moral, que no se centre tanto en contenidos como en facilitar que cada estudiante aprenda a buscarlos, hacerlos propios y los traduzca en compromisos de conducta personal. La propuesta educativa se presenta ejemplificada en una asignatura concreta, que sirve de hilo expositivo y ejemplo de aplicación. Tras una breve introducción sobre los indicadores de insostenibilidad, se (...) presenta la planificación, metodología y objetivo de la asignatura. A continuación, se reflexiona sobre dos de los obstáculos a los que se enfrenta la educación moral en la actualidad: la fragmentación del saber y la dificultad para que los aprendizajes teóricos se traduzcan en conductas. Por último, se exploran dos oportunidades para la educación moral que pueden facilitar ese vínculo: la búsqueda de las causas profundas de problemas ambientales y sociales actuales, y el empleo de la belleza.

After September 11, Sullivan wrote that while he wasn’t worried about the heartland, “decadent coastal liberals may well mount a fifth column.†This in response, as is well known, to a thoughtful New Yorker essay by Susan Sontag.

This book tells the story of the Scientific Buddha, "born" in Europe in the 1800s but commonly confused with the Buddha born in India 2,500 years ago. The Scientific Buddha was sent into battle against Christian missionaries, who were proclaiming across Asia that Buddhism was a form of superstition. He proved the missionaries wrong, teaching a dharma that was in harmony with modern science. And so his influence continues. Today his teaching of "mindfulness" is heralded as the cure for all (...) manner of maladies, from depression to high blood pressure.In this potent critique, a well-known chronicler of the West's encounter with Buddhism demonstrates how the Scientific Buddha's teachings deviate in crucial ways from those of the far older Buddha of ancient India. Donald Lopez shows that the Western focus on the Scientific Buddha threatens to bleach Buddhism of its vibrancy, complexity, and power, even as the superficial focus on "mindfulness" turns Buddhism into merely the latest self-help movement. The Scientific Buddha has served his purpose, Lopez argues. It is now time for him to pass into nirvana. This is not to say, however, that the teachings of the ancient Buddha must be dismissed as mere cultural artifacts. They continue to present a meaningful challenge, even to our modern world.

All paradoxes of self-reference seem to share some structural features. Russell in 1908 and especially Priest nowadays have advanced structural descriptions that successfully identify necessary conditions for having a paradox of this kind. I examine in this paper Priest’s description of these paradoxes, the Inclosure Scheme (IS), and consider in what sense it may help us understand and solve the problems they pose. However, I also consider the limitations of this kind of structural descriptions and give arguments against Priest’s use (...) of IS in favour of dialetheism. IS fails to identify sufficient conditions for having a paradox of self-reference. That means that, even if we identified a problem common to any reasoning satisfying IS, that problem would not explain why some of those reasonings are paradoxical and some others are not. Therefore IS cannot justify by itself the claim that some particular theory offers the best solution to the paradoxes of self-reference. We still need to consider aspects concerning the content and context of occurrence of every paradox. (shrink)

In contrast to individualistic explanations of social injustice that appeal to implicit attitudes, structural explanations are unintuitive: they appeal to entities that lack clear ontological status, and the explanatory mechanism is similarly unclear. This makes structural explanations unappealing. The present work proposes a structural explanation of one type of injustice that happens in conversations, discursive injustice. This proposal meets two goals. First, it satisfactorily accounts for the specific features of this particular kind of injustice; and second, it articulates a structural (...) explanation that overcomes their unattractiveness. The main idea is that discursive injustice is not the result of biased interlocutors, but of problematic discursive norms. (shrink)

Environmental sensitivity and Christianism Contemporary environmental sensitivity has characterized for decades the emerging culture in the developed world. It is not yet mainstream in influencing behavior at a global level, as the growing environmental impact of consumerism testifies particularly to it. Present day environmental sensitivity seems somehow at odds with Christianism, charged for decades alongside Judaism with major responsibility in the environmental crisis. This paper explains and discusses on seven interlinked aspects of the environmental value amply recognized across environmentalism. In (...) examining them, Christian environmentalism learns particularly some demands of the Christian vocation that may remain neglected and demand a moral conversion both of Christians and of no non-Christians and non-believers. In accepting this demand, the Christian discerns the life-giving presence of Christ in many traits of the environmental sensitivity and culture. This encounter offers grounds for a reciprocal understanding and enrichment of Christians and non-believers or non-Christians, towards the attainment of a wider and deeper respect of environmental and human shared values.

In Leibniz’s New Essays stands out, within many important topics, his doctrine of innate ideas, which supposes the division between sense knowledge and innate knowledge and implies the distinction between truths of reason and truths of fact. That doctrine is particularly relevant for Leibniz’s philosophy, but implicitly entails the epistemological difference between belief, on one hand, and certainty, on the other. In this paper I outline, according to my interpretation, how Leibniz explains that humans can have certainty about innate ideas. (...) This topic is important because if Leibniz demonstrates the possibility of having certainty of those ideas, then, it is feasible to believe in its existence. However, if his explanation is unsatisfactory his metaphysical doctrine would be seriously weakened and, at the same time, both skepticism and Locke’s empiricist doctrine would be reinforced.

Base-of-the-pyramid business models aim to achieve profitability and poverty reduction by including poor people into corporate value chains. This goal duality creates tensions. Actors’ responses to these tensions are influenced by their cognitive frames of the phenomena building the tension. Applying a cognitive perspective, I investigate how corporate actors with different frames of poverty respond proactively or defensively to the poverty–profitability tension by adapting business model elements. I find that proactive and defensive responses differ for actors holding different cognitive frames (...) of poverty. The responses have consequences for the poverty impact potential of BOP business models. (shrink)

Recent research on autonoetic consciousness indicates that the ability to remember the past and the ability to project oneself into the future are closely related. The purpose of the present study was to confirm this proposition by examining whether the relationship observed between personality and episodic memory could be extended to episodic future thinking and, more generally, to investigate the influence of personality traits on self-information processing in the past and in the future. Results show that Neuroticism and Harm Avoidance (...) predict more negative past memories and future projections. Other personality dimensions exhibit a more limited influence on mental time travel . Therefore, our study provide an additional evidence to the idea that MTT into the past and into the future rely on a common set of processes by which past experiences are used to envision the future.

En este trabajo exponemos algunas categorías modales orientadas al estudio y comprensión de los sistemas autoorganizados que muestran complejidad. Para ello centramos nuestra investigación en el área de la ecología y, más en particular, en el ámbito de la ecología aural, es decir, en el estudio de los sonidos que componen los ecosistemas. Las categorías modales aquí desarrolladas son, por un lado, la «repertorialidad», referida a la coherencia y estabilidad interna de todo sistema autoorganizado; la «disposicionalidad» o experimentación y variación (...) inherente a estos sistemas y, finalmente, el «paisaje», que tiene en consideración lo realmente efectivo, lo dado. Este conjunto de categorías nos lleva a explorar el sistema modal de necesidad-contingencia-posibilidad-imposibilidad, el cual, aplicado a los estudios sonoros se convierte en el juego de señales-redundancia-ruido-silencio. Estas categorías, aplicadas a ejemplos en la naturaleza, nos ayudan a comprender el devenir inherente a todo ecosistema. Finalmente, descubrimos cómo la investigación categorial de los paisajes sonoros aporta información sobre el comportamiento evolutivo y el estado de conservación de estos sistemas. (shrink)
