Argumentamos que el tipo de contextualismo que defendemos, el contextualismo integrativo, ofrece una manera de ordenar e integrar algunos de los distintos conceptos de justificación en pugna. Mostraremos de qué modo, puesto que cada uno de estos conceptos implica distintas intuiciones y estándares de justificación de una creencia, es posible distinguir diferentes contextos de atribución de justificación igualmente válidos entre sí. En particular, sostendremos que el contextualismo integrativo muestra que las disputas entre dos teorías de la justificación, a saber, el (...) externismo y el internismo, se establecen sobre el supuesto erróneo de que existe un único concepto válido de justificación.We shall argue that the kind of contextualism we defend, viz., the integrative contextualism, offers a way to coordinate and integrate some of the various competing concepts of justification. We shall show how, since each of these concepts involves different intuitions and standards of justification of beliefs, it is possible to distinguish different contexts of justification attribution, each of them, equally valid. In particular, the integrative contextualism, we defend, shows that disputes between two theories of justification, namely the externalist and internalist theories of justification, are established on the erroneous assumption thatthere is only one valid concept of justification.

Previous research addressing the association between leisure and happiness has given rise to the hypothesis that informal social activities might contribute more to happiness than solitary activities. In the current study, we tested how the two types of leisure—social and solitary—contribute to a person’s subjective sense of well-being. For the empirical estimate, we used four consecutive quarters of data collected from 533 people over the age of 16, from 13 Tsimane’ hunter-farmer villages in the Bolivian Amazon. Results suggest that only (...) social, not solitary, leisure has a positive and statistically significant association with subjective well-being. The association between solitary leisure and subjective well-being was negligible or negative. Future research should focus on emic definitions of social and solitary time, for solitary time might not always be equivalent to leisure and productive group activities might substitute for social leisure.

International research enrolling human subjects has raised an ethical concern regarding the just distribution of benefits between the countries that design the research and the host communities. Although several universal declarations have expressed this concern, a gap between theory and practice continues to exist, as well as a significant divergence between the design of the research protocol and the social context where it will be implemented. Although institutional review boards have made a valuable effort to evaluate international research, their sensitivity (...) to the just sharing of research benefits as well as their attention to the social context must be evaluated. This article analyzes the distribution of benefits in a review of international research in Mexico and produces an ethical reflection based on the results. (shrink)

El objetivo de este trabajo es reflexionar, a partir de algunos textos clave de Joseph Ratzinger, acerca de la relación que el cristianismo siempre ha tenido con la filosofía y con el tipo de racionalidad que se desarrolló en Occidente. El cristianismo nunca se ha asumido como una propuesta religiosa más, sino como "la verdad revelada". Desde sus orígenes ha tenido que convivir con múltiples ofertas religiosas y hoy en día no puede sustraerse a ello en un contexto marcado por (...) el pluralismo, como el de nuestra época. Esta condición le impele actualmente a reivindicar su carácter racional inherente y afrontar los desafíos que cierto irracionalismo de la cultura posmoderna le pone frente a sí. (shrink)

Después de los excesos y de las contradicciones a las que condujeron los diferentes humanismos que caracterizaron a la Modernidad, tanto ilustrada como tardía, el pensamiento contemporáneo ha caído en un pesimismo, hasta cierto punto justificado, respecto a las potencialidades emancipadoras y humanizadoras de la racionalidad autónoma y crítica que caracterizó a esa época. El pesimismo actual reniega del ser humano como valor y como ideal, también con cierta razón, abriendo el camino a una era antihumanista y posthumana. Desde el (...) punto de vista de la tradición cristiana se pretende recuperar el humanismo; no puede decirse que sea un nuevo humanismo pero sí uno originario. Lo que entenderemos aquí por humanismo cristiano es el resultado de la confluencia entre esas dos tradiciones que configuran el rostro de occidente,. Este debe ser un humanismo autocrítico, mesurado y autolimitado, que bajo el concepto de creaturalidad –y la contingencia que de él se deriva– pretende revalorar al hombre en el marco más general de su finitud y de su necesaria conformidad con la ley natural; de esta manera se busca recuperar ambas raíces y pilares que han definido a la cultura occidental.

As this article shows, the closeness between the work of the French Beguine and the late sermons in German by Meister Eckhart is perceptible. It is evident mainly through the analysis that both authors made of spiritual poverty. Nevertheless, the present work also reveals the fundamental differences that exist between the two mystics. Finally, it indicates the philosophical relevance of these two paradigmatic forms of mystical discourse.

Growing evidence suggests mothers invest more in girls than boys and fathers more in boys than girls. We develop a hypothesis that predicts preference for girls by the parent facing more resource constraints and preference for boys by the parent facing less constraint. We test the hypothesis with panel data from the Tsimane’, a foraging-farming society in the Bolivian Amazon. Tsimane’ mothers face more resource constraints than fathers. As predicted, mother’s wealth protected girl’s BMI, but father’s wealth had weak effects (...) on boy’s BMI. Numerous tests yielded robust results, including those that controlled for fixed effects of child and household. (shrink)

Background: Heart rate variability (HRV) has been considered as a measure of heart-brain interaction and autonomic modulation, and it is modified by cognitive and attentional tasks. In cognitive tasks, HRV was reduced in participants who achieved worse results. This could indicate the possibility of HRV predicting cognitive performance, but this association is still unclear in a high cognitive load sport such as chess Objective: To analyse modifications on HRV and subjective perception of stress, difficulty and complexity in different chess problem (...) tasks. Design: HRV was assessed at baseline. During the chess problems, HRV was also monitored, and immediately after chess problems the subjective stress, difficulty and complexity were also registered. Method: A total of 16 male chess players, age: 35.19 (13.44) and ELO: 1927.69 (167.78) were analysed while six chess problem solving tasks with different level of difficulty were conducted (two low level, two medium level and two high level chess problems). Participants were classified according to their results into two groups: high performance or low performance. Results: Friedman test showed a significant effect of tasks in HRV indexes and perceived difficulty, stress and complexity in both high and low performance groups. A decrease in HRV was observed in both groups when chess problems difficulty increased. In addition, HRV was significantly higher in the high performance group than in the low performance group during chess problems. Conclusions: An increase in autonomic modulation was observed to meet the cognitive demands of the problems, being higher while the difficulty of the tasks increased. Non-linear HRV indexes seem to be more reactive to tasks difficulty, being an interesting and useful tool in chess training. (shrink)

Automatic public malware analysis services provide controlled, isolated and virtual environments to analyse malicious software samples. Unfortunately, malware is currently incorporating techniques to recognize execution onto a virtual or sandbox environment; when an analysis environment is detected, malware behaves as a benign application or even shows no activity. In this work, we present an empirical study and characterization of automatic PMAS, considering 26 different services. We also show a set of features that allow to easily fingerprint these services as analysis (...) environments; the lower the unlikeability of these features, the easier for us to fingerprint the analysis service they belong to. Finally, we propose a method for these analysis services to counter or at least mitigate our proposal. (shrink)

RESUMEN Se muestra cómo la "inteligencia sentiente", en sus elementos "noológicos", adquiere cierto carácter "técnico" primario y constitutivo que se despliega en el logos y en la razón de manera individual, social e histórica.

ABSTRACT The paper shows how "sentient intelligence", in its noological elements, acquires a certain primary and constitutive "technological" character that is deployed individually, socially, and historically in logos and reason. The very viability of man's being in the world as a human animal is at stake in the primordial apprehension of reality, and the "technological" plays a relevant role here. It is in the primary noological elements of primordial apprehension that we find the bases for the emergence of "technology", which would then be not an accessory element, but a constitutive part of taking charge of reality.

We propose a revision operator on a stratified belief base, i.e., a belief base that stores beliefs in different strata corresponding to the value an agent assigns to these beliefs. Furthermore, the operator will be defined as to perform the revision in such a way that information is never lost upon revision but stored in a stratum or layer containing information perceived as having a lower value. In this manner, if the revision of one layer leads to the rejection of (...) some information to maintain consistency, instead of being withdrawn it will be kept and introduced in a different layer with lower value. Throughout this development we will follow the principle of minimal change, being one of the important principles proposed in belief change theory, particularly emphasized in the AGM model. Regarding the reasoning part from the stratified belief base, the agent will obtain the inferences using an argumentative formalism. Thus, the argumentation framework will decide which information prevails when sentences of different layers are used for entailing conflicting beliefs. We will also illustrate how inferences are changed and how the status of arguments can be modified after a revision process. (shrink)

El Institución Nacional de Servicio de Aprendizaje Comercial ofrece el programa “Preparación para el mundo del trabajo”, con el objetivo de formar profesionales competentes para desempeñarse en el entorno profesional. Este informe tuvo como objetivo reflejar la propuesta de la unidad curricular 1 del programa, que abordó la historia del mundo del trabajo, las relaciones laborales, el empleo y la profesión y busca provocar reflexiones que permeen el cotidiano del adolescente. Para ello se utilizó el material puesto a disposición por (...) la Institución al facilitador y la experiencia vivida por el autor al impartir el contenido propuesto. Esta unidad curricular discutió: 1) el trabajo formal y su relación o no con la vida cotidiana de los adolescentes; 2) las dificultades que enfrentan las instituciones para contratar jóvenes aprendices, especialmente aquellos con vulnerabilidad social. La clase se dividió en cuatro momentos: presentación dialogada del tema, presentación de conceptos a través de diapositivas por parte del facilitador, presentación de un video de “Charlie Chaplin: tiempos modernos” y discusión final combinando todas las etapas anteriores. La docente pudo observar que los adolescentes ampliaron su comprensión del mundo del trabajo, posicionándose como ciudadanos con derechos y deberes, percibiéndose como parte de un proceso de construcción del mundo. Se observó mayor autonomía y espacios para intercambios saludables entre pares, adolescentes y su facilitador, así como con sus familias, relatadas por ellos en ocasiones posteriores. Por lo tanto, la gestión del aula posibilitó nuevas experiencias, ocupando otros espacios sociales, ampliando las oportunidades y posibilidades del adolescente en el mundo, promoviendo la salud mental.

En este trabajo se explora una conexión entre el contextualismo y el fiabilismo. El propósito es desarrollar las líneas centrales de un acercamiento contextualista para resolver la crítica internista de que las nociones fiabilistas de justificación y de conocimiento no son adecuadas porque no recogen las intuiciones correspondientes a que un sujeto que está justificado o que sabe es racional y epistemológicamente responsable. Se argumenta que esta crítica y el escepticismo pirrónico comparten un presupuesto común, a saber, la cláusula internista, (...) por lo que, si es posible limitar el alcance de esta cláusula a través del contextualismo distinguiendo dos contextos diferentes, entonces también es posible hacer uso de esta distinción para dar respuesta a la crítica internista al fiabilismo. In this paper, we explore a connection between reliabilism and contextualism. our purpose is to draw up a contextualist approach to solve the critique that the reliabilist notions of justification and knowledge are not satisfactory because there is no room for the intuitions that a subject who is justified or knows is rational and epistemologically responsible. We will argue that this critique and the Pyrrohnian skepticism share the same assumption, viz., the internalist clause. Thus, if it is possible to limit the scope of this clause using contextualism, making a distinction between two different contexts, then it is also possible to use this distinction to offer an answer to the internalist critique to reliabilism.

John Quidort considers individual work, among other activities, the most suitable form of appropriation. Giles of Rome seems to share this view but, in contrast to John’s opinion, he claims that all possession is legitimate only when the owner is baptized, i.e., when he is part of the Church community. This view depends on Giles’s political thought, that the temporal order should be subordinated to the ecclesiastical order. John, on the other hand, when referring to the independence of the two (...) powers, considers work and other activities independent from the Church, although linked to Christian ethics. (shrink)
