Multiplicity of Beings according to Saint Thomas Aquinas is a book that aimed to find an explanation of beings' diversity on the grounds of the metaphysical intrinsic principles of beings identified by Aristótle. Are matter and form causes of identity, individuation and diversity of substances? Aquinas answers this question by means of some demonstrations grounded on the very nature of matter and form, in the line of the doctrines contained in book 7 of the Aristotle's Metaphysics.

This article analyzes Aristotle's argument on form as the primary substance and principle in Metaphysics Zeta 17 from the point of departure of the sense-perceptible substances subject to the becoming.

We present a formal analysis of Douglas Hofstadter’s concept of superrationality. We start by defining superrationally justifiable actions, and study them in symmetric games. We then model the beliefs of the players, in a way that leads them to different choices than the usual assumption of rationality by restricting the range of conceivable choices. These beliefs are captured in the formal notion of type drawn from epistemic game theory. The theory of coalgebras is used to frame type spaces and to (...) account for the existence of some of them. We find conditions that guarantee superrational outcomes. (shrink)

The notion of naivety is a form of classification and explanation of the social world. By applying Erving Goffman’s expression games model, it is observed that the notion of naivety corresponds to a situation in which an observer assumes that the observed subject does not accommodate his behavior to the presence of the observer, in the assumption that the latter might take advantage from what he learns from it. This article explores this model’s explanatory power in reference to the diverse (...) forms in which the notion of naivety is used in contexts where transinteractive structures of the art world have to be taken into account. La noción de ingenuidad es una forma cotidiana de clasificación y explicación del mundo social. Usando el modelo de juegos de expresión de Erving Goffman, se observa que ella corresponde a la situación en que un actor asume que otro no modifica su comportamiento teniendo en cuenta lo que el primero aprende de él para alcanzar sus propios objetivos. En este artículo se explora la utilidad de este modelo para explicar el uso de la noción de ingenuidad en referencia a estructuras transinteractivas de mundos del arte. (shrink)

En su teoría de la justicia como equidad, John Rawls sostiene que la estructura básica es el objeto primario de la justicia y que, por ende, quedan excluidas las decisiones personales. Esta posición sufre un giro insospechado en la visión rawlsiana sobre la justicia en el comunismo. En sus tres lecciones sobre Marx, Rawls presenta una doble valoración: por un lado, sostiene que el comunismo es justo en virtud de su distribución igualitaria; por otro, afirma que la ausencia de un (...) sentido de lo justo y de la obligación moral en la vida cotidiana hace que ésta sea una sociedad más allá de la justicia. La justicia ya no depende sólo de la operación de los primeros principios en la estructura básica, sino también de las actitudes personales. (shrink)

The problems that arise from the presence of self-attacking ar- guments and odd-length cycles of attack within argumentation frameworks are widely recognized in the literature on defeasible argumentation. This paper introduces two simple semantics to capture different intuitions about what kinds of arguments should become justified in such scenarios. These semantics are modeled upon two extensions of argumentation frameworks, which we call sustainable and tolerant. Each one is constructed on the common ground of the powerful concept of admissibility introduced by (...) Dung in [10]. The novelty of this approach consists in viewing the admissibility of a subset of arguments as relative to potentially challenging subsets of arguments. Both sustainable and tolerant semantics are more credulous than preferred semantics (i.e. they justify at least the same arguments, and possibly more). Given certain sufficient conditions they coincide among them as well as with other semantics introduced by Dung. (shrink)

In this paper we present an embedding of abstract argumentation systems into the framework of Barwise and Seligmans logic of information flow. We show that, taking P.M. Dungs characterization of argument systems, a local logic over states of a deliberation may be constructed. In this structure, the key feature of non-monotonicity of commonsense reasoning obtains as the transition from one local logic to another, due to a change in certain background conditions. Each of Dungs extensions of argument systems leads to (...) a corresponding ordering of background conditions. The relations among extensions becomes a relation among partial orderings of background conditions. This introduces a conceptual innovation in Barwise and Seligmans representation of commonsense reasoning. (shrink)

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

This paper shows the brain correlates of Cloninger’s personality model during the presentation of social scenarios under positive or negative valence situations. Social scenarios were constructed when participants played the Dictator game with two confederates that had two opposites roles as the cooperator and non-cooperator. Later the same day during a fMRI scanning session, participants read negative and positive situations that happened to confederates in the past. Participants were asked to think “how do you think those people felt during that (...) situation?” A dissimilarity matrix between stimuli were obtained from fMRI results. Results shown that Harm Avoidance trait people make use of right middle frontal gyrus and left superior frontal gyrus to discriminate between Coop and NoCoop. Cooperation as a trait makes use of the right superior temporal gyrus and the right precuneus to discriminate between Coop and NoCoop in positive social scenarios. Finally, Self-directedness trait people make use of the right inferior parietal lobe to discriminate between Coop and NoCoop in negative social scenarios and the right precuneus to discriminate between Coop and Strangers. An intuitive link between discrimination findings and behavioral patterns of those personality traits is proposed. (shrink)

Research has indicated that microRNAs (miRNAs), a special class of non-coding RNAs (ncRNAs), can perform important roles in different biological and pathological processes. miRNAs’ functions are realized by regulating their respective target genes (targets). It is thus critical to identify and analyze miRNA-target interactions for a better understanding and delineation of miRNAs’ functions. However, conventional knowledge discovery and acquisition methods have many limitations. Fortunately, semantic technologies that are based on domain ontologies can render great assistance in this regard. In our (...) previous investigations, we developed a miRNA domain-specific application ontology, Ontology for MIcroRNA Target (OMIT), to provide the community with common data elements and data exchange standards in the miRNA research. This paper describes (1) our continuing efforts in the OMIT ontology development and (2) the application of the OMIT to enable a semantic approach for knowledge capture of miRNA-target interactions.

Background Medical ethics deals with the ethical obligations of doctors to their patients, colleagues and society. The annual reports of Sri Lanka Medical Council indicate that the number of complaints against doctors has increased over the years. We aimed to assess the level of knowledge, attitude and practice regarding medical ethics among doctors in three teaching hospitals in Sri Lanka. Methods A hospital-based cross-sectional study was conducted among doctors using a pre-tested self-administered, anonymous questionnaire. Chi Squared test, and ANOVA test (...) were used to identify the significance of association between level of knowledge and selected factors. Results Most doctors had a poor level of knowledge on medical ethics, with postgraduate trainees showing significantly higher level of knowledge. The average knowledge on medical ethics among doctors was significantly different between the three hospitals. Over 95% had a favourable attitude towards gaining knowledge and advocated the need for training. The majority indicated awareness of unethical practices. 24.6% of respondents stated that they get a chaperone ‘sometimes’ during patient examination while 3.5% never do. The majority responded that they never accept gifts from pharmaceutical companies in recognition of their prescribing pattern. 12–41% of doctors participated in the study acknowledged that they ‘sometime’ engaged in unethical practices related to prescribing drugs, accepting gifts from pharmaceutical companies and when obtaining leave. Conclusion Most doctors had a poor level of knowledge of medical ethics. Postgraduate trainees had a higher level of knowledge than other doctors. The majority showed a favourable attitude towards gaining knowledge and the need of training. Regular in-service training on medical ethics for doctors would help to improve their knowledge on medical ethics, as well as attitudes and ethical conduct. (shrink)

El título de este libro, al estar en plural, constituye de por sí una petición de principio. Se trata, pues, de descomponer el Tiempo en tiempos y dentro de ellos analizar lo que son las secuencias de carácter temporal. Porque sólo rompiendo la interesada confusión del Tiempo con los tiempos puede pensarse de una forma "otra", puede empezar a repensarse el enorme sinsentido de la Estructura que nos atrapa, ratonera del pensamiento que adora la Realidad.

Estudio sistemático sobre la imagen y sus complejas relaciones con el lenguaje verbal, partiendo de una crítica al logocentrismo en su vertiente racionalista -que reduce el conocimiento y el pensamiento al discurso lingüístico- para desembocar en una teoría de la representación. El autor sostiene que la imagen va más allá de la representación al tornarse presencia, basándose en el examen de pensadores clásicos y teóricos actuales que han abordado cuestiones afines. Propone una teoría de la imagen que no se ciñe (...) sólo a lo visual, sino que reconoce las dimensiones no visuales de lo imaginal: "el principal objetivo de este libro es contribuir a la construcción de una filosofía de la imagen. Hoy en día es ya una necesidad urgente contar con un aparato conceptual que nos permita afrontar las distintas modalidades de lo imaginal, que aparecen en ámbitos tan diversos como la intimidad psicológica, la ciencia, la filosofía, la comunicación masiva, la religión, la educación, la propaganda o el arte".

A obra cultural, política e social de Leonardo Coimbra é a temática principal deste livro. De permeio é dada nota dos grandes traços e momentos da história da Primeira República Portuguesa, isso na justa dimensão em que tal ajuda à contextualização e melhor compreensão do objecto principal. O estudo desta extraordinária e multifacetada personalidade – filósofo, homem de ciência, escritor, orador exímio, pedagogo, político – e a análise da sua relação crítica com os poderes instituídos durante o período histórico em (...) apreço, dá-nos conta da enorme distância entre os projectos e intenções do movimento republicano e a obra social efectivamente conseguida pelo regime, ao mesmo tempo que se retratam as vicissitudes e os condicionamentos que a um tal resultado conduziram. Republicano de todas as horas, Leonardo nunca deixou de verberar no republicanismo aquilo que considerava serem erros de essência e de forma, desde os postulados positivistas até às lutas fratricidas em que, insensatamente, se empenharam os filhos da República. Mas também a sua palavra, celebrando momentos de heroicidade, de união, de glória, sobretudo um tributo ao povo republicano, ao povo humilde das grandes cidades, que tão abnegadamente amou a República e por ela se bateu. Uma chamada de atenção para um trajecto espiritual percorrido por esta figura de livre-pensador que, pouco a pouco, se foi aproximando de um cristianismo católico, acabando por se converter oficialmente a esta fé, uma semana antes da sua trágica morte. Fica-nos, por fim, o conhecimento da obra cultural de Leonardo e a perpetuação da mesma, primeiramente através de uma geração de discípulos que, de perto, privou com o Mestre e depois os discípulos dos discípulos, ou seja, uma segunda geração de seguidores, todos unidos pela figura e pelo legado cultural de Leonardo Coimbra, a quem alguém chamou, com felicidade, “Mestre dos Mestres”.

The purpose of the present systematic and critical review was to assess the findings and to identify the gaps in the literature concerning gay and bisexual fathers. A comprehensive search of relevant literature using electronic databases and reference lists for articles published until December 2016 was conducted. A total of 63 studies, spanning from 1979 to 2016, were collected. More than half of the studies were published after 2011 and the overwhelming majority were conducted in the United States. Nine themes (...) were identified in the studies reviewed: (1) Pathways to fatherhood; (2) Motivations for fatherhood; (3) Parenting experiences and childrearing; (4) Family life and relationship quality; (5) Gender and father identities and gender-role orientation; (6) Disclosure of sexual identity; (7) Social climate; (8) Father’s psychosocial adjustment; and (9) Children’s psychosocial adjustment. It was found that research on gay fatherhood appears to be more heterogeneous than on lesbian motherhood, perhaps because of the variety of pathways to parenthood (via co-parenting, adoption, fostering, or surrogacy). Two-father families are becoming more visible in research on sexual minority parenting and gradually transforming the conceptualization of parenting in family research. (shrink)

The prevalence and negative impact of brain disorders are increasing. Clinical Neuropsychology is a specialty dedicated to understanding brain-behavior relationships, applying such knowledge to the assessment of cognitive, affective, and behavioral functioning associated with brain disorders, and designing and implementing effective treatments. The need for services goes beyond neurological diseases and has increased in areas of neurodevelopmental and psychiatric conditions, among others. In Europe, a great deal of variability exists in the education and training of Clinical Neuropsychologists. Training models include (...) master’s programs, continuing education courses, doctoral programs, and/or post-doctoral specialization depending on the country, with no common framework of requirements, although patients’ needs demand equal competencies across Europe. In the past five years, the Standing Committee on Clinical Neuropsychology of the European Federation of Psychologists’ Association has conducted a series of surveys and interviews with experts in the field representing 30 European countries. The information, along with information from the existing literature, is used in presenting an overview of current and relevant topics related to policy and guidelines in the training and competencies in Clinical Neuropsychology. An option for the way forward is the EuroPsy Specialist Certificate which is currently offered in Work- and Organizational psychology and Psychotherapy. It builds upon the Basic Certificate and complements national standards without overriding them. General principles can be found that can set the basis for a common, solid, and comprehensive specialty education/training, sharpening the Neuropsychologists’ competencies across Europe. The requirements in Clinical Neuropsychology should be comparable to those for the existing specialty areas in the EuroPsy model. Despite the perceived challenges, developing a Specialist Certificate appears a step forward for the development of Clinical Neuropsychology. Recommendations are proposed towards a shared framework of competencies by the means of a common level of education/training for the professionals in Europe. Benchmarking training standards and competencies across Europe has the potential of providing protection against unqualified and ethically questionable practice, creating transparency, raising the general European standard, and promoting mobility of both Clinical Neuropsychologists and patients in Europe, for the benefit of the professional field and the population.
