An additional compartment of vaccinated individuals is considered in a SIS stochastic epidemic model with infection reintroduction. The quantification of the spread of the disease is modeled by a continuous time Markov chain. A well-known measure of the initial transmission potential is the basic reproduction number $$R_0$$, which determines the herd immunity threshold or the critical proportion of immune individuals required to stop the spread of a disease when a vaccine offers a complete protection. Due to repeated contacts between the (...) typical infective and previously infected individuals, $$R_0$$ overestimates the average number of secondary infections and leads to, perhaps unnecessary, high immunization coverage. Assuming that the vaccine is imperfect, alternative measures to $$R_0$$ are defined in order to study the influence of the initial coverage and vaccine efficacy on the transmission of the epidemic.

There have been two main lines in the literature on restricted games: the first line was started by Myerson (1977) that studied graph-restricted games an the second one was initiated by Faigle (1989). The present paper provides a unified way to look on the literature and establishes connections between the two different lines on restricted games. The strength and advantages of this unified approach becomes clear in the study of the inheritance of the convexity from the game to the restricted (...) game where an interesting result by Nouweland and Borm (1991) on the convexity of graph-restricted games is turned into a direct consequence of the corresponding result by Faigle (1989), by means of this relation.

The logic BN4 was defined by R.T. Brady in 1982. It can be considered as the 4-valued logic of the relevant conditional. E4 is a variant of BN4 that can be considered as the 4-valued logic of entailment. The aim of this paper is to define reduced general Routley-Meyer semantics for BN4 and E4. It is proved that BN4 and E4 are strongly sound and complete w.r.t. their respective semantics.

Atran conjectures that a triggering algorithm for a living- kind module could involve inputs from other modules that detect animacy and intentionality. Here we further speculate about how algorithms for detecting specific intentions could be used to trigger between- or within-species categorization. Such categorization may be adaptively important in Eldredge's energy and information realms.

Este trabajo consiste en una reconstrucción de los motivos de reflexión en ese ámbito privilegiado de la experiencia filosófica al que de la mano de Habermas, vamos a denominar pensamiento postmetafísico, como superación mediadora de la eterna disputa entre el pensar metafísico y el pensar antimetafísico. En él desarrollaremos aquellas categorías empírico-trascendentales que van a constituir las condiciones de posibilidad de esta nueva experiencia filosófica, a saber, racionalidad procedimental, razón sin trascendencia, razón comunicativa, giro lingüístico y deflación de lo extracotidiano.

Knowledge and true relations represent the principal task of Theory of Knowledge. This paper argues about various solutions to the justification of knowledge, given by William James, Richard Rorty and Jürgen Habermas. For classic Pragmatism Knowledge and Truth converge with the idea of a guideline, direction and orientation with an effective value for men. The Newpragmatism represented by Rorty tries out the way of the widest possible widening of justification contexts, taking as last referent the features of a western liberal (...) culture. Habermas pleads for a strong idealization in his discussion with Rorty up to the ideal speech situation. (shrink)

La tesis que deseo discutir en este trabajo es la siguiente: las ciencias humanas (ciencias del espíritu según Dilthey, ciencias histórico-hermenéuticas según Habermas) son posibles en la medida en que pueda ser epistemológicamente justificado el método que las hace posibles, a saber, la comprensión hermenéutica del sentido cuyo núcleo central lo constituye el círculo hermenéutico. Se trata, pues, de justificar epistemológicamente la hermenéutica como comprensión del sentido de las vivencias propias y ajenas, para lo cual es preciso analizar la reflexividad (...) y reciprocidad que impregna la estructura del lenguaje ordinario. En el diálogo que Habermas establece con Dilthey en Conocimiento e interés aparecen los suficientes argumentos para dicha fundamentación. Nuestro texto hará especial hincapié en los siguientes tópicos: distinción entre ciencias de la naturaleza y ciencias del espíritu, comprensión hermenéutica del sentido, lenguaje ordinario y reflexividad, especificidad del círculo hermenéutico, ciencia y contexto vital, y, finalmente, haremos un balance de la interpretación habermasiana de Dilthey a partir de las relaciones entre ciencias histórico-hermenéuticas e interés práctico del conocimiento.

I propose in this paper a reflection, a self-analysis, about my extensive teaching experience, not from a formal point of view of the specificity of the program and the subjects of my courses, but about the singularity of the teaching activities. The commitment with the students, with the topic taught and with the Institution in which I have the honor to work, constitute the fundamental motive that leads and conducts my profession as teacher. My explanation displays ten items. Each of (...) them presents a speculation about one of the ideal elements of the good teacher all of us aim to be. For that reason this essay is not a positivist description of the teaching reality, but it expects to reconstruct the critical demarcation between the ideality which all of us try to achieve and the empirical reality that constantly pull us in the opposite direction. The coercion without coercions of the exemplariness pushes us to maintain alive the faith in the appropriation of the nature and soul of the ideal teacher. (shrink)

The purpose of this article is to explore the concept of Philosophy within the works written by Wittgenstein if we take into account the ambivalent sense of the term phármakon. Thus, it will be outlined a contest of paradoxes between, on the one hand, healthiness, sanity, and the adaptable confidence produced by western rationality materialized into objective science, and, on the other hand, sickness, insanity, the world of perplexities, and the realm of desire and death, essential to philosophical thought. Bearing (...) in mind last Wittgenstein’s approaches, we will understand the Tractatus both critical to the deficiencies of western Reason and imprisoned within them. But the “enchanting” power of western Reason, conducting to identify rationality and scientificity in that work, will be conjured in the last Wittgenstein through the opening of plural realms of rationality and of discourses. In this way, philosophical questions will be rescued from silence and absurdity. (shrink)

In our time there is growing interest in developing a systematic approach to oncologic patients and end-of-life care. An important goal within this domain is to identify the values and ethical norms that guide physicians’ decisions and their recourse to technological aids to preserve life. Though crucial, this objective is not easy to achieve.

BackgroundRespect for confidentiality is important to safeguard the well-being of patients and ensure the confidence of society in the doctor-patient relationship. The aim of our study is to examine real situations in which there has been a breach of confidentiality, by means of direct observation in clinical practice.MethodsBy means of direct observation, our study examines real situations in which there has been a breach of confidentiality in a tertiary hospital. To observe and collect data on these situations, we recruited students (...) enrolled in the Medical Degree Program at the University of Cordoba. The observers recorded their entries on standardized templates during clinical internships in different departments: Internal Medicine; Gynecology and Obstetrics; Pediatrics; Emergency Medicine; General and Digestive Surgery; Maxillofacial Surgery; Plastic Surgery; Orthopedics and Traumatology; Digestive; Dermatology; Rheumatology; Mental Health; Nephrology; Pneumology; Neurology; and Ophthalmology.ResultsFollowing 7138 days and 33157 h of observation, we found an estimated Frequency Index of one breach per 62.5 h. As regards the typology of the observed breaches, the most frequent were related to the consultation and/or disclosure of clinical and/or personal data to medical personnel not involved in the patient’s clinical care, as well as people external to the hospital. As regards their severity, severe breaches were the most frequent, accounting for 46.7 % of all incidents. Most of the reported incidents were observed in public areas, such as corridors, elevators, the cafeteria, stairs, and locker rooms.ConclusionsIn addition to aspects related to hospital organization or infrastructure, we have shown that all healthcare personnel are involved in confidentiality breaches, especially physicians. While most are committed unintentionally, a non-negligible number are severe, repeated breaches, thus suggesting a certain carelessness, perhaps through ignorance about certain behaviors that can jeopardize patient confidentiality.

In the eukaryotic cell, DNA compaction is achieved through its interaction with histones, constituting a nucleoprotein complex called chromatin. During metazoan evolution, the different structural and functional constraints imposed on the somatic and germinal cell lines led to a unique process of specialization of the sperm nuclear basic proteins (SNBPs) associated with chromatin in male germ cells. SNBPs encompass a heterogeneous group of proteins which, since their discovery in the nineteenth century, have been studied extensively in different organisms. However, the (...) origin and controversial mechanisms driving the evolution of this group of proteins has only recently started to be understood. Here, we analyze in detail the histone hypothesis for the vertical parallel evolution of SNBPs, involving a “vertical” transition from a histone to a protamine‐like and finally protamine types (H → PL → P), the last one of which is present in the sperm of organisms at the uppermost tips of the phylogenetic tree. In particular, the common ancestry shared by the protamine‐like (PL)‐ and protamine (P)‐types with histone H1 is discussed within the context of the diverse structural and functional constraints acting upon these proteins during bilaterian evolution.

‘Banality of evil’ was a concept introduced by Hannah Arendt in order to characterize a new form of wickedness embodied in people as Adolf Eichmann and others nazis criminals. Arendt thougt that this perverseness was very awey from the one of ‘radical evil’, a notion built by Kant and employed by Arendt herself in former works. This article seeks to point out that concepts of radical evil and banality of evil are closer than Arendt recognizes.

The physician’s duty of confidentiality is based on the observance of the patient’s privacy and intimacy and on the importance of respecting both of these rights, thus creating a relationship of confidence and collaboration between doctor and patient. The main objective of this work consists of analyzing the aspects that are related to the confidentiality of patients’ data with respect to the training, conduct and opinions of doctors from different Clinical Management Units of a third-level hospital via a questionnaire. The (...) present study aimed to define the problem and determine whether the opinions of these professionals correspond to those observed in a previous work conducted at the same center. Of the 200 questionnaires that were collected, 62.5% were from consultants and the rest were from residents with an average of 14.4 ± 12.5 years in professional practice. The respondents noted habitual situations in which confidentiality was breached in the reference hospital. The section on their attitudes and behaviors towards situations related to confidentiality showed a slightly lower average score than that of their medical knowledge; significant differences in these scores were observed between the consultants and residents as well as between the extreme age groups and years of professional practice, thus more inadequate attitudes were consistently noted in younger doctors who had fewer years of experience. Finally, the respondents answered that the training of doctors in the aspects of healthcare law and ethics was the most important measure that the hospital could adopt regarding confidentiality practices.

Este artículo estudia la razón de Zambrano desde sus albores como razón mediadora. Su rechazo del sistema va unido a su comienzo en la intuición y a su decurso temporal, que analizamos en relación con Bergson y Husserl. La razón poética va más allá de ese núcleo intuitivo para revelar re-flexivamente incluso lo invisible. Su inmersión en las profundidades, en la pasividad actuante, en las entrañas, en la multiplicidad de los tiempos es paralela a la fenomenología de la génesis merleau-pontiana, (...) a su poiesis carnal e incluso al telos de una razón ampliada al sentir. Ambos filósofos ejercitan su nueva concepción de la filosofía en la existencia. (shrink)

It is the contention of this paper that the Merleau-pontynian primacy of perception is compatible with the importance of the imagination and other dimensions of embodied existence. In spite of the fact that these dimensions have important differences, they spring from the same source: the lived body and its operative intentionality. I analyze their implications in the Merleaupontinian conception of the Flesh in order to apply his Phenomenology of the imagination to undertand the current iconic turn.

A partir del comentario hecho por José L. L. Aranguren sobre «puede» y «debe» en ética, aquí se plantea el significado de los principios de ética en la situación de retroceso democrático del siglo XXI. Ha sido analizada por la filosofía y la teoría política recientes. En los años sesenta, las críticas de D. Sternberger al modelo de polis, de política cívica en las obras de H. Arendt, se apoyaban en la imagen de la ciudad hundida. Pero las preguntas sobre (...) el alcance del realismo («puede») y el lugar de los principios («debe») siguen abiertas. ¿Ultra posse nemo obligatur? Aquella imagen de la polis puede ser reemplazada por otra algo distinta, la ciudad sumergida. Se encuentra en la literatura, sería también la metáfora de la necesaria reconstrucción de las políticas democráticas, con el «deber ser» como núcleo de la cultura cívica. Los principios éticos y, en especial, justicia como equidad será aquí la referencia en dos situaciones: (1) la política de salud pública, (2) los procesos de paz. En conclusión, el marco normativo cuenta o ha de contar, tanto en la paz como en la guerra. Decir «nunca más» es también una forma de recordar el papel crucial de los principios. (shrink)

Audio description remains the cornerstone of accessibility for visually impaired audiences to all sorts of audiovisual content, including porn. Existing work points to the efficacy of audio description to guarantee immersion and emotional engagement, but evidence on its role in sexual arousal and engagement in porn is still scant. The present study takes on this challenge by comparing sighted and visually impaired participants’ experiences with porn in terms of their physiological response [i.e., cortisol and heart rate ] and self-report measures (...) of affect [Positive and Negative Affect Schedule ; Watson et al., 1988], anxiety [State-Trait Anxiety Inventory ; Spielberger et al., 1970], sexual reactivity and arousal [Sexual Inhibition/Sexual Excitation Scale ; Moyano and Sierra ; and the Ratings of Sexual Arousal ; Mosher ], and narrative engagement or transportation [The Transport Narrative Questionnaire, Green and Brock ]. 69 Spanish participants were allocated into three different groups: 25 sighted participants who watched and heard the porn scenes in their audio-visual version ; 22 sighted participants who listened to the audio described version without images ; and 22 visually impaired participants who also listened to the audio described version without images. Overall, results on physiological and self-report measures revealed no significant differences between groups or different versions of the clips. The analysis of cortisol reactivity to porn as the maximum increase or decrease in cortisol with respect to baseline values revealed no significant differences between the groups, but pointed to a higher percentage of non-responders than responders in the three groups, the highest being found in the ONCE group. As for participants’ cardiac response to the clips, no significant differences were found across the groups, with the highest HR levels being registered in the baseline phase. Self-report measures revealed significant between-group differences in negative affect. The ONCE group displayed the highest pre-task levels of negative affect and was the only group that showed a decrease in negative affect after exposure to the clips. Sighted and visually impaired participants reported to be moderately aroused and immersed in the films, regardless of exposure to AV or AD porn. In addition, correlations found between participants’ levels of self-report sexual arousal and transportation and post-task affect pointed to a positive relationship between exposure to porn and perceived levels of sexual arousal and affect. Results from the study reflected the efficacy of audio description in providing sighted and visually impaired audiences with a similar experience to that offered by original AV porn scenes. This study is exploratory but provides valid, initial groundwork for further research on the impact of audio description on porn reception. (shrink)

The goal of this paper is to examine whether business performance is affected by the adoption of practices included under the term Corporate Social Responsibility (CSR). To achieve this goal, we analyse the relation between CSR and certain accounting indicators and examine whether there exist significant differences in performance indicators between European firms that have adopted CSR and others that have not. The effects of compliance with the requirements of CSR were determined on the basis of firms included in the (...) Dow Jones Sustainability Index (DJSI), and specific accounting indicators were applied to measure performance. For the purposes of this study, we selected one group of firms belonging to the DJSI and another comprised of firms quoted on the Dow Jones Global Index (DJGI) but not on the DJSI. The sample was made up of two groups of 55 firms, studied for the period 1998–2004. Empirical analysis supports the conclusion that differences in performance exist between firms that belong to the DJSI and to the DJGI and that these differences are related to CSR practices. We find that a short-term negative impact on performance is produced. (shrink)

Objective: To measure the stability of life-sustaining treatment preferences amongst older people and analyse the factors that influence stability. Design: Longitudinal cohort study. Setting: Primary care centres, Granada (Spain). Eighty-five persons age 65 years or older. Participants filled out a questionnaire with six contexts of illness (LSPQ-e). They had to decide whether or not to receive treatment. Participants completed the questionnaire at baseline and 18 months later. Results: 86 percent of the patients did not change preferences. Sex, age, marital status, (...) hospitalisation, and self-perception of health and pain did not affect preferences. Morbidity and the death of a relative did. Conclusion: Stability of preferences of older persons in relation to end-of-life decisions seems to be more probable than instability. Some factors, such as the death of a relative or the increase in morbidity, can change preferences. These findings have implications for advance directives (ADs) and advance care planning. (shrink)

The logics BN4 and E4 can be considered as the 4-valued logics of the relevant conditional and (relevant) entailment, respectively. The logic BN4 was developed by Brady in 1982 and the logic E4 by Robles and Méndez in 2016. The aim of this paper is to investigate the implicative variants (of both systems) which contain Routley and Meyer’s logic B and endow them with a Belnap-Dunn type bivalent semantics.

Ideal rods and clocks are defined as an infinitesimal symmetry of the spacetime, at least in the non-quantum case. Since no a priori geometric structure is considered, all the possible models of spacetime are obtained.

Valerie Plumwood introduced in "Some false laws of logic" a series of arguments on how the rules Exported Syllogism, Disjunctive Syllogism, Commutation, and Exportation are not acceptable. Based on this we define the class of Plumwood algebras - logical matrices that do not verify any of these theses. Afterwards we provide conditional variants of the characteristic matrix of the logic RM3 that are also Plumwood algebras. These matrices are given an axiomatization based on First Degree Entailment and are endowed with (...) Belnap-Dunn Semantics. Finally we provide results of Soundness and Completeness in the strong sense for each of the defined variants. (shrink)

Six interesting variants of the logics BN4 and E4—which can be considered as the 4-valued logics of the relevant conditional and entailment, respectively—were previously developed in the literature. All these systems are related to the family of relevant logics and contain Routley and Meyer's basic logic B, which is well-known to be specifically associated with the ternary relational semantics. The aim of this paper is to develop reduced general Routley-Meyer semantics for them. Strong soundness and completeness theorems are proved for (...) each one of the logics. (shrink)
