Proof-theoretic methods are developed for subsystems of Johansson’s logic obtained by extending the positive fragment of intuitionistic logic with weak negations. These methods are exploited to establish properties of the logical systems. In particular, cut-free complete sequent calculi are introduced and used to provide a proof of the fact that the systems satisfy the Craig interpolation property. Alternative versions of the calculi are later obtained by means of an appropriate loop-checking history mechanism. Termination of the new calculi is proved, and (...) used to conclude that the considered logical systems are PSPACE-complete. (shrink)

Food advertising targeted at children is associated with the development of unhealthy eating habits and childhood obesity. In Spain, where one in every three children suffers from overweight, a voluntary regulation mechanism has been adopted to control such advertising, despite evidence of its ineffectiveness. This study's stated objective was to evaluate the grounds for implementing a policy that would ban the advertising of energy-dense, nutrient-poor food and beverages targeted at children in Spain, incorporating an ethical perspective in the analysis. Using (...) a bibliographic search of various databases, we reviewed the evidence for answering the seven questions posed by Walton et al.'s ethical evaluation framework, drawn up on the basis of the Nuffield Council on Bioethics Stewardship model. The results show that the proposed intervention is cost-effective, minimally intrusive, promotes healthy environments, acts on a vulnerable population, helps children lead healthy lifestyles, reduces social health inequalities, increases parents' individual freedom of choice and enjoys the support of scientists, health professionals and consumers alike. Accordingly, we feel that the time has come for food advertising directed to children in Spain to be statutorily regulated, by banning the promotion of EDNP products. (shrink)

Cet article soulève la difficulté majeure que rencontrent certaines institutions spécialisées dans le traitement de l’obésité pédiatrique pour travailler avec les familles. Ces familles sont au cœur de la problématique de ces jeunes : la séparation de l’enfant d’avec ses proches est la base thérapeutique, mais la dépendance est forte et la séparation d’avec les parents, la mère en particulier, difficile. Dans une perspective psychodynamique, les auteurs, chercheurs en psychologie, partent du postulat que l’obésité d’un individu serait révélatrice de conflits (...) intrapsychiques, intersubjectifs, mais aussi d’un symptôme familial transgénérationnel impactant la contenance du groupe. L’institution pourrait alors assurer une fonction substitutive de contenance auprès de ces familles en fragilité d’enveloppes psychiques. À partir d’un exemple clinique institutionnel, l’article montre l’impact dynamique de divers dispositifs thérapeutiques sur l’évolution de l’accompagnement des familles en souffrance de séparation.

We consider the concept of poverty from the asset-accumulation approach and propose an integrated framework, building upon existing theories, to describe how the interconnected factors of trust (or lack thereof) and social distance can reinforce poverty traps. Social distance is influenced by choice, while trust is the symptom that defines the strength of social ties on a group. We look at how an absence of trust influences how households make decisions about the use and accumulation of assets in ways that (...) could perpetuate poverty. Weak trust also affects how groups interact with each other in a society, creating “trust clusters” within homogeneous groups and antagonism across groups, which in turn affects aspirations and leads to an erosion of the basis of a social contract. For more effective and sustainable poverty reduction, we need to understand these linkages and address them systematically. (shrink)

Sara Ahmed piensa las emociones, los objetos, los espacios y las orientaciones hacia el mundo a partir de sus efectos. Las emociones son realidades públicas que nos pegan y nos separan de los otros, adquiriendo su significación política en el contacto social. La idea de la pegajosidad y el contacto presupone una subjetividad indisociable de su relación con la alteridad. Para explicar esta relación entre el yo y el mundo, Ahmed hace uso de la fenomenología. Una fenomenología queer consistirá en (...) sacar a la luz el fondo de historias, normas y signos que los espacios normativos y los objetos familiares ocultan al presentarse como atemporales y naturales. En este trabajo propongo que la filosofía de Ahmed permite leer las orientaciones, la subjetividad y las emociones en su dimensión narrativa. El protagonismo que adquieren las historias en la teoría queer de Ahmed es útil para pensar el vínculo entre literatura y política a partir de la recepción y la circulación de las obras. Las narrativas feministas contribuyen a generar extrañamiento respecto del mundo normativo, a dislocar el orden familiar. Estos dislocamientos abren grietas desde las que imaginar, a través de la literatura, maneras no normativas de desear y percibir el mundo. (shrink)

The kantian concept of friendship has been recently but yet scarcely studied. However, it has its place as the conclusion of the doctrine of virtue, which gives it some prominence. This article argues that the kantian approach to friendship, as it emerges from the analysis of the texts of the Metaphysics of Morals and the Lectures on Ethics, involves elements that connect with our contemporary sensibility and, far from being a marginal concept in his ethical philosophy, represents one of its (...) crucial moments.

The thesis that I intend to address in this article can be summarized with the idea that positive bonds1 engender not only dependence, but also freedom and autonomy. Accordingly, it is worth asking what positive human bonds are based on. Or, to phrase the question another way, how can dependence and autonomy be blended when we talk about relationships in terms of bonds, that is, relationships with a special quality of union?

The exegesis of the resurrection of Lazarus offers Hilary of Poitiers the chance to reflect on the emotional suffering of the Word made flesh and its glorification by the Father. The bishop uses these motifs to rebut the subordinationist position of his adversaries and to uphold the presence of the Father in the Son, declaring the perfect equality of both persons. Thus, he uses the miracle of the resurrection of Lazarus to show how the glorification of the Son is intended (...) to sanctify the flesh he assumed, so that the Father to recognizes him in it, thus restoring the unity of his divine and human natures. Likewise, he draws a connection with Jn 5:24-29, reinforcing his thoughts on the mystery of the mutual inhabitation of the Father and the Son with an anti-Arian interpretation. (shrink)

Cet article s’intéresse au phénomène des violences conjugales en montrant l’intérêt de considérer l’articulation des enveloppes psychiques au niveau individuel, familial et « couplal ». Il met le projecteur sur les matériaux psychiques transmis de génération en génération, qui traversent ces contenants. Si certaines traces du passé sont conscientes et élaborées, d’autres demeurent inconscientes et empreintes de traumatismes.

To define the concept of reason, to determine its modus operandi and its scope has constituted the philosopher's task from its origins till today. What follows does not intend to exhaust the meaning of reason, not even within the frame of Agustinian philosophy, since the term itself is not univocal in Agustinian philosophy, but rather to offer an analysis of rationality, in its cognitive function, and point out its relationship whit the soul, and its possible objects of knowledge -God among (...) 9thers- and in doing so, to offer a perspective which reconciles points of view somewhat reductionist.

The documentary genre is one of the audiovisual mechanisms with the greatest media efficiency in the transmission of reality. However, depending on the nature of the story, the construction of the textual and audiovisual discourse is altered. In this article, we consider the following questions: Is the documentary a format that is faithful to reality? What modifications does the discourse undergo so that the story is enhanced? To go deeper into this aspect, we intend to analyse the different elements that (...) make up the documentary discourse in its transition from reality to fictionalised narrative. To this end, an inspection of the environmental dissemination documentary My Octopus Teacher (Netflix, 2020) will be carried out. An audiovisual proposal in which the coexistence between human and animal life turns environmental dissemination into a powerful instrument for transmitting scientific knowledge. (shrink)

Cette recherche s’intéresse aux problématiques de ruptures de liens dans la clinique du placement familial, notamment celles rattachées au conflit de loyauté pouvant être ressenti par des adolescents placés. Ce syndrome, qui peut être baptisé « syndrome de la couverture tirée », correspond à un phénomène de rivalité entre deux familles, une professionnelle et une biologique avec comme enjeu central l’adolescent. À partir d’une étude de cas paradigmatique menée dans le cadre de suivis thérapeutiques associés à une recherche exploratoire, les (...) auteures, thérapeutes et chercheuses en psychologie clinique, procèdent à une analyse des phénomènes psychiques sous-jacents individuels et familiaux en s’appuyant sur les théories psychanalytiques groupales et familiales.

As Social Economy financial institutions, credit unions have traditionally been considered less efficient than traditional banking entities. However, like banks and savings banks, they have to be as efficient and competitive as possible to survive in today’s business environment, especially at times of crisis. To date, there have been very few studies on their efficiency and practically none for the crisis period. Moreover, almost all the existing studies assess only financial efficiency, without considering their social function. This study examines the (...) levels of both financial and social efficiency in Spanish credit unions as well as their main determinants during the recent crisis. We apply the two-stage double bootstrap data envelopment analysis methodology based on panel data corresponding to all the credit unions active in Spain between 2008 and 2013. The empirical results indicate that financial and social efficiency achieved an acceptable level, although on average the former was slightly greater than the latter. We also find that both age and merger and acquisition activity were positively influential on the financial efficiency of credit unions but had a significant negative effect on their social efficiency. Moreover, the regional location of such entities and the financial crisis were also crucial determinants of both types of efficiency. Our findings are therefore useful for all the stakeholders of credit unions to know if these entities have been efficient according to a double bottom line accounting in the crisis period and hence to maintain successful social management that is compatible with satisfactory financial efficiency.

L’influence du corpus paulinien sur l’œuvre et la pensée d’Hilaire de Poitiers est évidente autant dans l’approche exégétique de l’évêque vis-à-vis des textes bibliques que dans les sujets qu’il traite. Parmi ceux-ci, la justification par la foi fait l’objet d’un développement remarquable dans ses œuvres principales, en particulier dans le Commentarium in Matthaeum, dans laquelle l’évêque de Poitiers souligne la capacité exclusive de la foi pour justifier l’être humain et l’impuissance des œuvres pour l’atteindre. Cette radicalité apparente de son approche (...) dans sa première œuvre connue a donné lieu à une compréhension partiale du traitement que fait Hilaire de la justification par la foi.

India is the emerging country with the world’s greatest social banking program, so Indian banks are required to finance the weaker sectors of society that are excluded from the traditional financial system, while also providing mainstream banking services to non-priority sectors. For social banks to promote the ethical–social management of their dual mission and to be successful in today’s business environment, they must be as efficient as possible in both dimensions of their banking activity. Whereas the efficiency of Indian banks (...) in the financial dimension is well understood, to date there has been no research evaluating their double bottom-line of achieving social and financial goals. Our study applies an innovative Network Slack-Based DEA model to evaluate how efficient Indian public banks are when providing credit to priority and non-priority sectors. We also explore the main factors influencing bank efficiency. Results suggest that Indian public banks have performed relatively well in both activities, although social efficiency has been slightly greater than financial efficiency. Moreover, their commitment to priority sector lending has not come into conflict with the profit-seeking objectives of mainstream banking services. As regards determinants of social and financial efficiency, there are countervailing forces played by regional wealth, bank size, branch networks, and rural location. Our findings are therefore useful for stakeholders of Indian public banks as they indicate if these entities have adequately managed their double bottom-line, and hence if they are critical for poverty alleviation and development in India.

Drawing on the Agency-Stewardship approach, which suggests that manager profile may range from the agent model to the steward model, this article aims to examine how important CEOs are to corporate social responsibility (CSR). Specifically, this exploratory study proposes the existence of a relationship between manager profile and CSR practices and that this relation is mediated by the perceived role of ethics and social responsibility. After applying a mediated regression analysis using survey information collected from 149 CEOs in Spain, results (...) show that those closer to the steward model are more inclined to attach great importance to ethics and social responsibility, and to implement CSR practices in their companies. Results also provide support for the suggested mediating effect. Thus, this article extends research in understanding top managers as drivers for CSR and suggests new ways to deal with this issue empirically. (shrink)

En 1964, Glauber Rocha dirigió la película Dios y el Diablo en la Tierra del Sol. Año en el que Brasil sufrió el golpe de estado militar. En este momento, hablar de política o problemas sociales era un asunto turbio debido a la fuerte amenaza de represión.

Para el director, la religión guarda una relación muy estrecha con la política.

Fibromyalgia is a chronic pain syndrome characterized by dysfunctional processing of nociceptive stimulation. Neuroimaging studies have pointed out that pain-related network functioning seems to be altered in these patients. It is thought that this clinical symptomatology may be maintained or even strengthened because of an enhanced expectancy for painful stimuli or its forthcoming appearance. However, neural electrophysiological correlates associated with such attentional mechanisms have been scarcely explored. In the current study, expectancy processes of upcoming laser stimulation (painful and non-painful) and (...) its further processing were explored by event-related potentials (ERPs). Nineteen fibromyalgia patients and twenty healthy control volunteers took part in the experiment. Behavioral measures (reaction times and subjective pain perception) were also collected. We manipulated the pain/no pain expectancy through an S1–S2 paradigm (cue-target). S1 (image: triangle or square) predicted the S2 appearance (laser stimulation: warmth or pinprick sensation). Laser stimuli were delivered using a CO2 laser device. Temporal and spatial principal component analyses were employed to define and quantify the ERP component reliability. Statistical analyses revealed the existence of an abnormal pattern of pain expectancy in patients with fibromyalgia. Specifically, our results showed attenuated amplitudes at posterior lCNV component in anticipation of painful stimulation that was not found in healthy participants. In contrast, although larger P2 amplitudes to painful compared to innocuous events were shown, patients did not show any amplitude change in this laser-evoked response as a function of pain predictive cues (as occurred in the healthy control group). Additionally, analyses of the subjective perception of pain and reaction time indicated that laser stimuli preceded by pain cues were rated as more painful than those signaling non-pain expectancy and were associated with faster responses. Differences between groups were not found. The present findings suggest the presence of dysfunction in pain expectation mechanisms in fibromyalgia that eventually may make it difficult for patients to correctly interpret signs that prevent pain symptoms. Furthermore, the abnormal pattern in pain expectancy displayed by fibromyalgia patients could result in ineffective pain coping strategies. Understanding the neural correlates of pain processing and its modulatory factors is crucial to identify treatments for chronic pain syndromes. (shrink)
