Background: Intravenous fluids and/or antibiotics are applied to only a limited extent in Norwegian nursing homes, and the patients are often sent to hospital in these situations. A transfer and a stay in hospital may be unnecessary strains for frail older patients. Given this background, a collaborative research project was initiated in a Norwegian county in 2009. A teaching programme was developed, which aimed to strengthen the awareness of ethics, assessments and practical procedures related to intravenous fluid and/or antibiotics among (...) healthcare professionals. Objectives: This qualitative study aimed to increase our knowledge of the ethical problems experienced by nursing home nurses in situations related to the administration of intravenous fluids and/or antibiotics. Research design: An exploratory design was used, and five focus group interviews were conducted with 26 registered nurses. A hermeneutic analytic approach was applied. Ethical considerations: This study was reported to the Norwegian Social Science Data Services in May 2010. The Regional Committee for Medical and Health Research Ethics approved the collaborative research project. Findings: The analysis showed that the nurses experienced difficult decision-making situations, which were interpreted as external pressure and internal pressure. External pressure emerged in interactions with patients and relatives. Organizational factors were also interpreted as external pressure. Internal pressure was interpreted as the nurses’ experience of feeling inadequate in situations where it was difficult to protect the dignity of patients. Discussion: These findings correspond with international studies, which show that ethical problems often arise during decision-making situations. Conclusion: In agreement with the definition of an ethical problem, we found that the nurses experienced uncertainty and disagreements about how situations should be managed. External and internal pressures related to intravenous fluids and/or antibiotics in nursing homes have not been reported in previous studies. Thus, these findings merit further exploration. (shrink)

Rooth & Partee (1982) and Rooth (1985) have shown that the English-specific rule-by-rule system of PTQ can be factored out into function application plus two transformations for resolving type mismatch (type lifting and variable binding). Building on these insights, this article proposes a universal system for type-driven translation, by adding two more innovations: local type determination for gaps (generalizing Montague 1973) and a set of semantic filters (extending Cooper 1983). This system, dubbed Cross-Linguistic Semantics (XLS), is shown to account for (...) various phenomena — including scope relations in English and Greenlandic Eskimo, internally headed relative clauses in Lakhota, serial verbs in Yoruba and VP ellipsis in English.

We conducted three studies to examine how the recipients of negative workplace gossip judge the gossip sender’s morality and how they respond behaviorally. Study 1 provided experimental evidence that gossip recipients perceive senders as low in morality, with female recipients rating the sender’s morality more negatively than male recipients. In a follow-up experiment (Study 2), we further found that perceived low morality translates into behavioral responses in the form of career-related sanctions by the recipient on the gossip sender. A critical (...) incident study (Study 3) enhanced the external validity and extended the moderated mediation model by showing that gossip recipients also penalize senders with social exclusion. We discuss the implications for practice and research on negative workplace gossip, gender differences in attributions of morality, and gossip recipients’ behavioral responses. (shrink)

Recent years have witnessed an increasing growth in mutual funds that invest according to social criteria. As a consequence, the financial performance of these portfolios has attracted the interest of academics and practitioners. This paper investigates the performance of a sample of socially responsible mutual funds from seven European countries investing globally and/or in the European market. Using unconditional and conditional models, we assess the performance of these funds in comparison to conventional and socially responsible benchmark portfolios. The results show (...) that European socially responsible funds present in general neutral performance in relation to both conventional and socially responsible benchmarks. However, performance estimates seem to be slightly higher when funds are evaluated in relation to socially responsible indices. Our results also show that socially responsible funds are more exposed to conventional than to socially responsible indices. Furthermore, conventional benchmarks are better able to explain fund returns than socially responsible benchmarks. These findings are robust to both unconditional and conditional models of performance. We also observe that conditional models lead to a slight improvement of performance estimates and to the explanatory power of the models, both when conventional and socially responsible benchmarks are considered. This is consistent with most previous empirical findings on conditional performance evaluation. Our results show that investors who wish to hold European funds can add social screens to their investment choices without compromising financial performance. (shrink)

Most online platforms are becoming increasingly algorithmically personalized. The question is if these practices are simply satisfying users preferences or if something is lost in this process. This article focuses on how to reconcile the personalization with the importance of being able to share cultural objects - including fiction – with others. In analyzing two concrete personalization examples from the streaming giant Netflix, several tendencies are observed. One is to isolate users and sometimes entirely eliminate shared world aspects. Another tendency (...) is to blur the boundary between shared cultural objects and personalized content, which can be misleading and disorienting. A further tendency is for personalization algorithms to be optimized to deceptively prey on desires for content that mirrors one’s own lived experience. Some specific - often minority targeting -“clickbait” practices received public blowback. These practices show disregard both for honest labeling and for our desires to have access and representation in a shared world. The article concludes that personalization tendencies are moving towards increasingly isolating and disorienting interfaces, but that platforms could be redesigned to support better social world orientation.

The incommensurability thesis, as introduced by T.S. Kuhn and P.K. Feyerabend, states that incommensurable theories are conceptually incompatible theories which share a common domain of application. Such claim has often been regarded as incoherent, since it has been understood that the determination of a common domain of application at least requires a certain degree of conceptual compatibility between the theories. The purpose of this work is to contribute to the defense of the notion of local or gradual incommensurability, as proposed (...) by late Kuhn. The application of this notion would allow to render the incommensurability thesis coherent. To support this view, a typical example of incommensurability will be formally analyzed by applying the structuralist metatheory developed, among others by W. Balzer, C.U. Moulines and J.D. Sneed. The structural reconstruction of the relation between the phlogiston theory and the oxygen theory offered here will reveal that they are locally incommensurable, and will even make possible to determine the ontological reduction relation that they also exemplify.

A political discourse of peace marked the distribution and use of radioisotopes in biomedical research and in medical diagnosis and therapy in the post-World War II period. This occurred during the era of expansion and strengthening of the United States' influence on the promotion of sciences and technologies in Europe as a collaborative effort, initially encouraged by the policies and budgetary distribution of the Marshall Plan. This article follows the importation of radioisotopes by two Spanish research groups, one in experimental (...) endocrinology and one in molecular biology. For both groups foreign funds were instrumental in the early establishment of their laboratories. The combination of funding and access to previously scarce radioisotopes helped position these groups at the forefront of research in Spain. (shrink)

The discovery of so-called ‘mirror neurons’ - found to respond both to own actions and the observation of similar actions performed by others - has been enormously influential in the cognitive sciences and beyond. Given the self-other symmetry these neurons have been hypothesized as underlying a ‘mirror mechanism’ that lets us share representations and thereby ground core social cognitive functions from intention understanding to linguistic abilities and empathy. I argue that mirror neurons are important for very different reasons. Rather than (...) a symmetric ubiquitous or context- independent mechanism, I propose that these neurons are part of broader sensorimotor circuits, which help us navigate and predict the social affordance space that we meet others in. To develop both the critical and positive project I analyze the interpretive choices and the debate surrounding the mirror neuron research and show how the field is marred by highly questionable assumptions about respectively motor and social cognition. The discovery of mirror neurons - and the sensorimotor circuits of which these neurons are a part – actually empirically challenge many of these tacit assumptions. Findings of sensorimotor goal representations at levels of abstraction well beyond actual sensory information and kinetic movements challenge the idea of motor cognition as primarily output production. Additionally, the focus on 3rd person mindreading of hidden mental states is misguiding the field of social cognition. Much ‘mind-reading’ seems rooted in sensorimotor representations and a developmentally primary 2nd person understanding of actions and the mental lives of others, which precisely breaks the assumed dichotomy between mind and behavior. I propose a Social Affordance model where parallel fronto-parietal sensorimotor circuits support representations not just of other people’s actions but of the overall social affordance space. It is a process that monitors concrete goals and teleological possibilities that the environment affords respectively oneself and other present agents. With this model I hypothesize that the complex spectrum of sensorimotor integrations are indeed essential not only to normal action choice calibration but also to social cognitive abilities, as the sensorimotor teleological representations let us relate to others and understand their action choices in a shared pragmatic and intentional context.

What would it mean to do justice to testimonies of traumatic experience? That is, how can experiences which do not fit the customary scripts of sense-making be heard? Whereas processes of official memorialization or legal redress often demand that victims and survivors convey their experiences through familiar modes of narration, in my project on ‘grammars of listening’ or ‘gramáticas de lo inaudito’ I want to ask how it might be possible to hear these experiences on their own terms and what (...) the challenges are that we encounter when trying to do so. What I ultimately want to argue is that doing justice to trauma requires a profound philosophical questioning of the conditions that allow us to listen to testimony, and a true reckoning of the responsibility that we bear as listeners.

Mirror neuron research has come a long way since the early 1990s, and many theorists are now stressing the heterogeneity and complexity of the sensorimotor properties of fronto-parietal circuits. However, core aspects of the initial ‘ mirror mechanism ’ theory, i.e. the idea of a symmetric encapsulated mirroring function translating sensory action perceptions into motor formats, still appears to be shaping much of the debate. This article challenges the empirical plausibility of the sensorimotor segregation implicit in the original mirror metaphor. (...) It is proposed instead that the teleological organization found in the broader fronto-parietal circuits might be inherently sensorimotor. Thus the idea of an independent ‘purely perceptual’ goal understanding process is questioned. Further, it is hypothesized that the often asymmetric, heterogeneous and contextually modulated mirror and canonical neurons support a function of multisensory mapping and tracking of the perceiving agents affordance space. Such a shift in the interpretative framework offers a different theoretical handle on how sensorimotor processes might ground various aspects of intentional action choice and social cognition. Mirror neurons would under the proposed “social affordance model” be seen as dynamic parts of larger circuits, which support tracking of currently shared and competing action possibilities. These circuits support action selection processes—but also our understanding of the options and action potentials that we and perhaps others have in the affordance space. In terms of social cognition ‘ mirror ’ circuits might thus help us understand not only the intentional actions others are actually performing—but also what they could have done, did not do and might do shortly.

The present paper proposes an emergentist reading of Peirce, with special reference to his concept of evolution. Although the author never adopts the word “emergence” in a technical manner, it will be demonstrated that the core problem of emergence lies at the heart of his evolutionary doctrine, generally displayed by the interplay of his three well-known categories of Firstness, Secondness and Thirdness. Indeed, although the Classical pragmatists most quoted in connection to emergentism are Dewey and Mead (and William James to (...) some degree), scholars have recently suggested some emergentist readings of Peirce’s thought (cf. above all Tiercelin 1998, Quieroz & El-Hani 2006, Rose 2016), in particular with regard to semiotic process and cosmogony. Exploring further the path opened by those researches, the present paper aims to clarify the theoretical problem of emergent evolution from a pragmatist perspective and especially to illustrate Peirce’s emergentist standpoint. In order to reach this goal, the article is divided into four parts: after (1) a brief introduction to the contemporary debates on emergence, (2) I give a historical overview of Classical Pragmatism and British Emergentists, (3) with a special focus on the common roots of the British Emergentists and Peirce on evolution. Finally, (4) I offer an emergentist reading of Peirce’s theory of evolution. In particular, I show how his strong emphasis on chance and the “growth” of the universe go together with his arch-stone of synechism (that is his theory of continuity), through what he calls agapasm.

Current technology and surveillance practices make behaviors traceable to persons in unprecedented ways. This causes a loss of anonymity and of many privacy measures relied on in the past. These de facto privacy losses are by many seen as problematic for individual psychology, intimate relations and democratic practices such as free speech and free assembly. I share most of these concerns but propose that an even more fundamental problem might be that our very ability to act as autonomous and purposive (...) agents relies on some degree of privacy, perhaps particularly as we act in public and semi-public spaces. I suggest that basic issues concerning action choices have been left largely unexplored, due to a series of problematic theoretical assumptions at the heart of privacy debates. One such assumption has to do with the influential conceptualization of privacy as pertaining to personal intimate facts belonging to a private sphere as opposed to a public sphere of public facts. As Helen Nissenbaum has pointed out, the notion of privacy in public sounds almost like an oxymoron given this traditional private-public dichotomy. I discuss her important attempt to defend privacy in public through her concept of ‘contextual integrity.’ Context is crucial, but Nissenbaum’s descriptive notion of existing norms seems to fall short of a solution. I here agree with Joel Reidenberg’s recent worries regarding any approach that relies on ‘reasonable expectations’ . The problem is that in many current contexts we have no such expectations. Our contexts have already lost their integrity, so to speak. By way of a functional and more biologically inspired account, I analyze the relational and contextual dynamics of both privacy needs and harms. Through an understanding of action choice as situated and options and capabilities as relational, a more consequence-oriented notion of privacy begins to appear. I suggest that privacy needs, harms and protections are relational. Privacy might have less to do with seclusion and absolute transactional control than hitherto thought. It might instead hinge on capacities to limit the social consequences of our actions through knowing and shaping our perceptible agency and social contexts of action. To act with intent we generally need the ability to conceal during exposure. If this analysis is correct then relational privacy is an important condition for autonomic purposive and responsible agency—particularly in public space. Overall, this chapter offers a first stab at a reconceptualization of our privacy needs as relational to contexts of action. In terms of ‘rights to privacy’ this means that we should expand our view from the regulation and protection of the information of individuals to questions of the kind of contexts we are creating. I am here particularly interested in what I call ‘unbounded contexts’, i.e. cases of context collapses, hidden audiences and even unknowable future agents. (shrink)

As users of computer networks have become more active in producing their own electronic records, in the form of transcripts of onlinediscussions, ethicists have attempted to interpret this new situation interms of earlier models of personal data protection. But thistransference results in unprecedented problems for researchers. Thispaper examines some of the central dichotomies and paradoxes in thedebate on research ethics online in the context of the concrete study ofa virtual community that we carried out. We argue that alienation, notprivacy, is (...) the actual core of the ethical problems of virtual communityresearch. While practically everybody is allowed and often welcome tojoin online communities (which undermines the claim to privacy), mostparticipants would agree that members and visitors are not authorized touse, or `harvest,'' or sell the product of the group communication. To dothat, they would be expected to ask for permission preferably before thecontent has been produced, thus granting participants'' right to controltheir own product. This `non-alienation principle'' should be the basisof emergent social conventions in cyberspace. It would apply toresearchers as to anyone else. With certain types of research, wesuggest, cyberspace provides unique opportunities for empoweringsubjects by involving them as contributors in the research project. (shrink)

In this article, I will draw on my own work and related publications to present some intuitions and hypotheses about the nature of the self and the mechanisms that lead to the development of consciousness or self awareness in human infants during the first 6 months of life. My main purpose is to show that the origins of a concept of self include the physical and the mental selves. I believe that it is essential when trying to understand what a (...) mental state is, that one identifies the social and physical aspects of the person to whom the mental state belongs. How can one identify a mental state or thought without making reference to a subject who experiences it (Hobson, 1990)? The other important feature of the self is that it is distinguished from other people and inanimate objects. ‘One's concept of self is a concept of a person; one's concept of persons cannot be a concept applicable only to a single individual (oneself), for the reason that in this case it would no longer constitute a concept'(Hobson, 1990, p. 165). I would like to argue that infants must be able to represent their physical and social selves in order to recognize that they are similar and different from other people, and to develop expectations and predictions about the behaviour of others (theory of mind). Unlike Strawson, I do not believe that the social and physical aspects of the self are, or become redundant to the nature of the self. I posit that the mature conscious self is a unique mythical and constantly changing entity, the formation of which is created not by the individual alone, but through continuous dialectical inquiry with other people.

This paper presents an overview of my work in philosophy from my first book on Friedrich Schiller and the political sublime to my most recent project on listening to traumatic forms of violence. Starting with a reflection on the autobiographical character of philosophy, I propose to take up the question of an aesthetic dimension of philosophical critique, where aesthetics is understood as an always already embodied perspective on the world, on truth, and on philosophical activity, as well as an always (...) already political realm, where the distribution of sense pre-determines our approach and articulation of experience. Departing from aesthetics understood and deployed as critique, the paper moves on to ask about the specific frameworks of sense or grammars that determine in advance the conditions of audibility in the realms of memory-building and history-making—particularly in those contexts where historical, political, and institutional forms of violence produce silencing and erasure. Putting in dialogue the latter with decolonial studies, I (re)interpret “traumatic violence” as a colonizing form of violence, understanding that one of its central aspects is that it is not only an assault on life but on the conditions of production of sense that make life legible as such. In this context, my project on grammars of listening seeks to carefully unpack these complex intersections while also explaining why I believe that a radical form of listening is an essential subversive/imaginative strategy against traumatic/colonial violence.

The paper offers insights into the acceptability of ethical issues in poultry production and how this situation provides an opportunity to transform the prevailing system into a more sustainable one. The survey among German consumers reveals that killing day-old chicks is a well-known practice and is rated as “very problematic”. In contrast, dual-purpose chickens are mostly unknown but are considered a positive alternative to killing day-old chicks. Consumer clusters were identified regarding purchasing criteria for dual-purpose chickens, purchasing routines and socio-economic (...) factors. Three of the five clusters—the perfectionists, idealists, and realists—turned out to be potential buyers. To develop a suitable marketing strategy, it is recommended that the added value of dual-purpose chickens be comprehensibly communicated. From a multi-level perspective, rearing dual-purpose chickens has a competitive disadvantage compared to system-compliant alternatives. Through increasing external pressure, the different alternatives can jointly contribute to a regime shift. (shrink)

Although the STS literature on boundary-work recognizes that such work unfolds within a “terrain of uneven advantage” vis-à-vis gender, race, and other inequalities, reflection about that uneven advantage has been strikingly underdeveloped. This article calls for a retheorizing of boundary-work that engages more actively with feminist, critical race, and postcolonial scholarship and examines more systematically the relation between scientific boundary-work, broader structures of sociopolitical inequality, and boundary-workers’ positionality. To demonstrate the need for this retheorization, I analyze ethnographic and interview data (...) on scientific boundary-work in the natural and social sciences in Portugal, showing that scholars’ gender, sexuality, race, ethnicity, and nationality affect the success of their boundary-work. I suggest, therefore, that in unequal societies where credibility is unevenly distributed, the conditions are not in place for some scholars’ boundary-work to work. I draw on Sara Ahmed to argue that we must conceptualize scientific boundary-work as always potentially performative, but not always successfully so, and explicitly interrogate the actual conditions of performativity. Recognizing the links between inequality, embodiment, and non-performativity in scientific boundary-work will enable STS to better understand, and hopefully transform, the relations between contingent struggles over scientificity and entrenched structures of power.

This paper explores the way in which Agamben takes part in the dialogue on “impolitical communities” that was inaugurated by J. L. Nancy and was soon followed by authors like M. Blanchot, J. Derrida and R. Esposito, among others. Although Agamben’s ontological exploration of ‘whatever being,’ followed later by the political idea of form-of-life, are still very close particularly to Nancy’s work, the article will show in which ways Agamben’s view of a political coming community explores different paths and moves (...) in unusual registers, that help to understand in new ways the kind of inoperativeness involved in a contemporary rethinking of community. The notion of experience of thought as potentiality and its relationship to that “tiny displacement” of the world which Agamben seems to connect with his idea of a coming community will play a central role in the analysis.

: The Hamblin-Karttunen approach has led to many insights about questions in English. In this article the results of this rule-by-rule tradition are reconsidered from a crosslinguistic perspective. Starting from the type-driven XLS theory developed in Bittner (1994a, b), it is argued that evidence from simple questions (in English, Polish, Lakhota and Warlpiri) leads to certain revisions. The revised XLS theory then immediately generalizes to complex questions — including scope marking (Hindi), questions with quantifiers (English) and multiple wh-questions (English, Hindi, (...) Japanese). Eliminating language- and construction-specific information from the compositional rules, in favor of universal semantic filters, leads to analyses that not only generalize across unrelated languages but are also empirically more accurate, not less.

Se pondrá a (...) prueba la hipótesis de que sus reapropiaciones del mesianismo convergen en sus consideraciones sobre la historia, aunque no obturan sus diferencias en relación al sujeto histórico; éstas se traducen en distancias políticas que dan cuenta del escenario heterogéneo al interior de la izquierda alemana en el período 1920-1921.

The rapid and unplanned change to teaching and learning in the online format brought by COVID-19 has likely impacted many, if not all, aspects of university students' lives worldwide. To contribute to the investigation of this change, this study focuses on the impact of the pandemic on student well-being, which has been found to be as important to student lifelong success as their academic achievement. Student well-being has been linked to their engagement and performance in curricular, co-curricular, and extracurricular activities, (...) intrinsic motivation, satisfaction, meaning making, and mental health. The purpose of this study was to examine how student perceptions of their degree completion and future job prospects during the pandemic impact their well-being and what role university support plays in this relationship. We used the conservation of resources theory to frame our study and to develop five hypotheses that were later tested via structural equation modeling. Data were collected from 2,707 university students in France, Germany, Russia, and UK via an online survey. The results showed that university support provided by instructors and administration plays a mediating role in the relationship between the perceived impact of COVID-19 on degree completion and future job prospects and levels of student well-being. Student well-being is decreased by their concerns for their degree completion but not by their concerns for future job prospects. In turn, concerns for future job prospects affect student well-being over time. These results suggest that in a “new normal,” universities could increase student well-being by making support to student studies a priority, especially for undergraduates. Also, universities should be aware of the students' changing emotional responses to crisis and ensure visibility and accessibility of student support. (shrink)

The cohesin complex is best known for its role in sister chromatid cohesion. Over the past few years, it has become apparent that cohesin also regulates gene expression, but the mechanisms by which it does so are unknown. Recently, three groups mapped numerous cohesin-binding sites in mammalian chromosomes and found substantial overlap with the CCCTC-binding factor (CTCF).1-3 CTCF is an insulator protein that blocks enhancer–promoter interactions, and the investigators found that cohesin also contributes to this activity. Thus, these studies demonstrate (...) at least one mechanism by which cohesin can control gene expression. BioEssays 30:715–718, 2008. © 2008 Wiley Periodicals, Inc. (shrink)

How do we perceive the agency of others? Do the same rules apply when interacting with others who are radically different from ourselves, like other species or robots? We typically perceive other people and animals through their embodied behavior, as they dynamically engage various aspects of their affordance field. In second personal perception we also perceive social or interactional affordances of others. I discuss various aspects of perceptible agency, which might begin to give us some tools to understand interactions also (...) with agents truly other than ourselves or “perhaps agents” like present and future social robots. Robots have various kinds of physical and behavioral presence and thus make their agency—if we want to call it that—perceptible in ways that computers and other forms of AI do not. The largely dualist assumptions pertaining to the hidden bodies of traditional Turing tests are discussed, as well as the social affordance effects of such indirect interactions as opposed to interactions in physically shared space. The question is what role various abilities to reveal, hide and dynamically control the body and broader behavior plays in heterogeneous tech or machine mediated interactions. I argue that the specifics and richness of perceptible agency matters to the kind of reciprocity we can obtain. (shrink)

Here, we aim at elucidating the epistemic grounds by which scientists traverse the path from ignorance to insight to scientific understanding- within the realm of empirical sciences, specifically focusing on cases marked by the existence of recalcitrant anomalies. We contend that scientific understanding is structuralist. Furthermore, we contend that the partial overcoming of anomalies between scientific theory and observation resides in the finding of some structures that allow for reconciliation and integration of the resulting inconsistencies and explanatory gaps by providing (...) novel inferential pathways and ways of making sense of dependency relations. Moreover, we claim that this type of understanding is gradual in that it begins with insight, understood in our view as a way of grasping what type of structure might be helpful in overcoming the above difficulties and leading eventually to a more full-blown understanding involving systematic integration and subsumption of theoretical posits and empirical observations within theoretical structures.

This paper presents an experimental study investigating artificial grammar learning (AGL) in monolingual and bilingual children, with and without dyslexia, using an original methodology. We administered a serial reaction time (SRT) task, in the form of a modified Simon task, in which the sequence of the stimuli was manipulated according to the rules of a simple Lindenmayer grammar (more specifically, a Fibonacci grammar). By ensuring that the subjects focused on the correct response execution at the motor stage in presence of (...) congruent or incongruent visual stimuli, we could meet the two fundamental criteria for implicit learning: the absence of an intention to learn and the lack of awareness at the level of resulting knowledge. The participants of our studies were four groups of 10-year-old children: 30 Italian monolingual typically developing children, 30 bilingual typically developing children with Italian L2, 24 Italian monolingual dyslexic children and 24 bilingual dyslexic children with Italian L2. Participants were administered the modified Simon task developed according to the rules of the Fibonacci grammar and tested with respect to the implicit learning of three regularities: (i) a red is followed by a blue; (ii) a sequence of two blues is followed by a red and (iii) a blue can be followed either by a red or by a blue. Results clearly support the hypothesis that implicit learning took place, since participants of all groups became increasingly sensitive to the structure of the input, implicitly learning the sequence of the trials and thus appropriately predicting the occurrence of the relevant items, as manifested by faster reaction times in predictable trials. Moreover, group differences were found, with bilinguals being overall faster than monolinguals and dyslexics less accurate than controls. Finally, an advantage of bilingualism in dyslexia was found, with bilingual dyslexics performing consistently better than monolingual dyslexics and, in some conditions, at the level of the two control groups. These results are taken to suggest that bilingualism should be supported also among linguistically impaired individuals. (shrink)

We introduce new proof systems for propositional logic, simple deduction Frege systems, general deduction Frege systems, and nested deduction Frege systems, which augment Frege systems with variants of the deduction rule. We give upper bounds on the lengths of proofs in Frege proof systems compared to lengths in these new systems. As applications we give near-linear simulations of the propositional Gentzen sequent calculus and the natural deduction calculus by Frege proofs. The length of a proof is the number of lines (...) in the proof. A general deduction Frege proof system provides at most quadratic speedup over Frege proof systems. A nested deduction Frege proof system provides at most a nearly linear speedup over Frege system where by "nearly linear" is meant the ratio of proof lengths is O) where α is the inverse Ackermann function. A nested deduction Frege system can linearly simulate the propositional sequent calculus, the tree-like general deduction Frege calculus, and the natural deduction calculus. Hence a Frege proof system can simulate all those proof systems with proof lengths bounded by O). Also we show that a Frege proof of n lines can be transformed into a tree-like Frege proof of O lines and of height O. As a corollary of this fact we can prove that natural deduction and sequent calculus tree-like systems simulate Frege systems with proof lengths bounded by O. (shrink)

Este artículo examina las novelas El espíritu de mis padres sigue subiendo en la lluvia (2011), de Patricio Pron, y Yo la quise (2019), de Josefina Giglio, con énfasis en las formas de narrar, desde donde se analiza una tensión entre la experiencia vivida y su devenir en un artificio transitando la relación entre literatura y memoria desde la perspectiva de la generación nacida durante la dictadura argentina. Así, el estudio recupera el concepto de espacio biográfico postulado por Arfuch, articulado (...) con la noción de plan perteneciente a Deleuze-Guattari y la de cronotopo de Bajtín. En la novela de Pron, el retorno de un joven escritor a la Argentina constituye el punto de inflexión a partir del cual se encabalga la historia de la desaparición de Alberto (2008), la de Alicia desaparecida en Tucumán (1976), y la de los padres del escritor, militantes de la Guardia de Hierro. En Giglio, la arquitectónica entreteje la historia del personaje Yo, un escritor reconocido, quien se halla frente a la imposibilidad de transformar en materialidad ficcional una relación amorosa de la juventud; la de Ella, una militante del partido comunista; y la de la Nena, quien relata la convivencia con su hermano y sus abuelos después de la desaparición de sus padres. Ambas novelas remiten a las preguntas sobre cómo narrar la experiencia y bajo qué formas enunciar para hacer visible el acontecimiento histórico. El artículo contribuye al campo de los estudios de la memoria y sus lenguajes artísticos, la literatura de la generación nacida en 1970.. (shrink)

Most of the free will debate operates under the assumption that classic determinism and indeterminism are the only metaphysical options available. Through an analysis of Dennett’s view of free will as gradually evolving this article attempts to point to emergentist, interactivist and temporal metaphysical options, which have been left largely unexplored by contemporary theorists. Whereas, Dennett himself holds that “the kind of free will worth wanting” is compatible with classic determinism, I propose that his models of determinism fit poorly with (...) his evolutionary theory and naturalist commitments. In particular, his so-called “intuition pumps” seem to rely on the assumption that reality will have a compositional bottom layer where appearance and reality coincide. I argue that instead of positing this and other “unexplained explainers” we should allow for the heretical possibility that there might not be any absolute bottom, smallest substances or universal laws, but relational interactions all the way down. Through the details of Dennett’s own account of the importance of horizontal transmission in evolution and the causal efficacy of epistemically limited but complex layered “selves,” it is argued that our autonomy is linked to the ability to affect reality by controlling appearances.

El Programa de filosofía con y para niños ‘FiloHilo’ surgió de la posibilidad de trasladar desde el Prácticum a las aulas procesos de innovación y renovación pedagógica basados en el diálogo y la práctica filosófica. Son multitud los estudios que nos permiten afirmar que la Filosofía para niños/as se ha transformado en una actividad efectiva, posible y necesaria para todas las edades, ya que atiende a la necesidad propia del ser humano: la pregunta, el cuestionamiento, la duda. Pero estos procesos (...) se instauran si hay una actitud de apertura y disposición por parte del profesorado: esa primera condición, la actitud de apertura y disposición, es sobre la que se centra este artículo y fue el germen de preguntas clave: ¿cómo percibe el profesorado estas prácticas?, ¿las conocen?, ¿las han utilizado alguna vez?, ¿tienen predisposición a su implantación?, ¿está preparado para desarrollar un pensamiento ético, reflexivo, solidario y crítico en las aulas? Con el objetivo de responder a ello, se elaboró un cuestionario compuesto por 31 ítems y 4 dimensiones, que posee altos niveles de fiabilidad (α=0.949). Fue enviado a todos los centros educativos gallegos y respondido por 167 docentes. Los resultados muestran una alta predisposición hacia la práctica filosófica, fundamentalmente, por apoyar el razonamiento crítico y la toma de conciencia. Se concluye demandando un abordaje diferente de la enseñanza de la filosofía, tomando en cuenta las necesidades y los intereses del profesorado e introduciendo la necesidad de formación en el ámbito de la práctica filosófica, entendiendo la filosofía como algo que se practica y puede transformar la vida de los alumnos y alumnas: autoconocimiento y autorrealización.

Una investigación que se centra en torno a la fuerza de la imaginación con el propósito básico de alcanzar una aproximación desde perspectivas plurales, diversas al poder humano de imaginar. La imaginación es una función compleja que exige ser abordada desde diversos ángulos, cada uno de los cuales arrojará una luz parcial sobre determinados aspectos y facetas pero no sobre otros, no sobre todos.
