El artículo esboza algunos hitos fundamentales del desarrollo de las ciencias sociales en el siglo XX que dieron cabida al interés por las vidas ordinarias, en disputa con el privilegio de atención concedido entonces a las élites y los grandes personajes, de donde se configura un marco epistemológico que acoge el estudio de los individuos y grupos sociales subordinados en la modernidad, dotado de un nuevo arsenal de métodos y técnicas basados en los testimonios orales y documentos personales. A través (...) del seguimiento de dicha ruta, condicionada por los múltiples tributos de las ciencias de la cultura, la literatura, la sistematización del pensamiento pedagógico y la variopinta experiencia histórica global, se comprenden las condiciones de emergencia del paradigma biográfico narrativo en educación.

El problema de la intencionalidad ha sido el foco de discusiones losó cas desde sus inicios hasta el día de hoy y las diferentes explicaciones que se han dado al respecto han dado pie a la construcción de sistemas losó cos de todo tipo. Lo común a estos sistemas ha sido el uso del término intencionalidad, en sentido losó co, separado del de intención, en el sentido vulgar, pese a que ambos son actos voluntarios dirigidos hacia objetos. Dicho uso da (...) lugar a confusiones que evitan la producción de nuevo conocimiento y que, para ser aclaradas, implican un nuevo tratamiento de la intencionalidad, para la cual es útil la losofía del lenguaje y de la mente de John Searle. Mediante la lectura crítica de algunos de sus textos más representativos al respecto y de algunos autores que han hecho un análisis de ellos, este artículo comienza clari cando el concepto de intencionalidad, entendiéndolo como una característica, tanto de la conciencia, como de la voluntad. Luego, expone a grandes rasgos la teoría de la intencionalidad en John Searle, pasando de los actos de habla a los estados mentales. Por último, describe los rasgos constitutivos del lenguaje humano y lo compara con el lenguaje computacional. Se concluye que la intencionalidad es una característica hasta ahora exclusiva de los seres humanos y que está en directa relación con el lenguaje y el seguimiento de reglas. (shrink)

Virtual reality is a useful tool to study consumer behavior while they are immersed in a realistic scenario. Among several other factors, personality traits have been shown to have a substantial influence on purchasing behavior. The primary objective of this study was to classify consumers based on the Big Five personality domains using their behavior while performing different tasks in a virtual shop. The personality recognition was ascertained using behavioral measures received from VR hardware, including eye-tracking, navigation, posture and interaction. (...) Responses from 60 participants were collected while performing free and directed search tasks in a virtual hypermarket. A set of behavioral features was processed, and the personality domains were recognized using a statistical supervised machine learning classifier algorithm via a support vector machine. The results suggest that the open-mindedness personality type can be classified using eye gaze patterns, while extraversion is related to posture and interactions. However, a combination of signals must be exhibited to detect conscientiousness and negative emotionality. The combination of all measures and tasks provides better classification accuracy for all personality domains. The study indicates that a consumer’s personality can be recognized using the behavioral sensors included in commercial VR devices during a purchase in a virtual retail store. (shrink)

This study compares cognitive and emotional responses to 360-degree vs. static (2D) videos in terms of visual attention, brand recognition, engagement of the prefrontal cortex, and emotions. Hypotheses are proposed based on the interactivity literature, cognitive overload, advertising response model and motivation, opportunity, and ability theoretical frameworks, and tested using neurophysiological tools: electroencephalography, eye-tracking, electrodermal activity, and facial coding. The results revealed that gaze view depends on ad content, visual attention paid being lower in 360-degree FMCG ads than in 2D (...) ads. Brand logo recognition is lower in 360-degree ads than in 2D video ads. Overall, 360-degree ads for durable products increase positive emotions, which carries the risk of non-exposure to some of the ad content. In testing four ads for durable goods and fast-moving consumer goods (FMCG) this research explains the mechanism through which 360-degree video ads outperform standard versions. (shrink)

Eliminating pain is problematic when it comes to caring for people with disabilities or chronic pain. This paper locates the drive to completely eliminate pain as a project of the Enlightenment and contrasts it with the tradition of interpreting suffering throughout the Christian tradition. I introduce Jane Austen’s novel Mansfield Park as a way to continue the tradition of interpretative suffering after the Enlightenment. Using textual analysis of Jane Austen’s Mansfield Park, I demonstrate how the novel’s heroine, Fanny Price, is (...) able to resist the drive to eliminate pain through her contemplative reflection on suffering which allows her to participate in right relationships with others and God. Finally, I offer twenty-first century applications of Mansfield Park by addressing changes we can make in the church and the clinic to understand better the role pain plays in Christian life and community.

A partir de investigaciones realizadas en la Universidad Católica de Chile entre 1979 y 1984 se pudo constatar la creciente influencia que la filosofía católica tuvo en Chile desde fines del siglo XIX y primera mitad del siglo pasado, producto, especialmente de la influencia que la Encíclica Aeterni Patris de León XIII, promulgada en 1879, y la acción que la propia Universidad Católica, tuvo en la intelectualidad católica chilena. De esta forma surgieron destacados pensadores chilenos que desde una perspectiva de (...) pensamiento católico incursionaron en la metafísica (Lira Pérez, Finlayson, Gandolfo y Martínez), en la difusión de la filosofía cristiana (Miller, Restat, Escudero, Larson, Silva, Rosales y Jiménez), en la filosofía del derecho (Peragallo y Lira Ulrquieta), en la filosofía política (Frei, Castillo y Bustos) y en la filosofía de la educación (Hurtado); la mayoría hace su análisis y aporte desde el tomismo o desde el neotomismo (Maritain), sin descuidar el diálogo con otras posturas y filósofos de otras posiciones.

The classification of ageing as a disease is fundamental to developing new pharmacological strategies that can target said phenomenon. The European Medicines Agency does not do this and maintains a questionable perspective based on the traditional naturalistic argument and the value-free ideal. An alternative is proposed which, inspired by consequentialism, is committed to considering ageing as a disease in European regulatory contexts as long as the ethical consequences are desirable. Within a realistic framework, I show that making this decision would (...) have moderate positive effects such as increased knowledge about antiageing pharmacology or potential greater chances of completing vital projects. Furthermore, we will see that the main arguments used by critics to show that the negative effects outweigh the positive ones are not sound. Therefore, I conclude that it would be beneficial for the European Medicines Agency to change its position on ageing. (shrink)

_Higher Education and the Color Line_ examines the role of higher education in opening up equal opportunity for mobility in American society--or in reinforcing the segregation between white and nonwhite America. In the wake of the U.S. Supreme Court's landmark decision upholding affirmative action, this comprehensive and timely book outlines the agenda for achieving racial justice in higher education in the next generation. Weaving together current research and a discussion of overarching demographic, legal, and political issues, the book focuses on (...) the racial transformation of higher education and the structural barriers that perpetuate racial stratification at the postsecondary level. _Higher Education and the Color Line_ includes chapters that outline the demographic changes in elementary, secondary, and postsecondary school enrollment; the evolving role of law and policy; the barriers faced by minority college students; and the kinds of programs that best serve them. Topics addressed include financial aid; the role of community colleges; nontraditional paths to postsecondary education; and the role of higher education in social and economic mobility. In addition to providing a thorough and up-to-date assessment of the state of racial integration in higher education, the book goes beyond the usual black-and-white analysis to provide a multiethnic perspective supported by extensive new data. Taken together, these discussions examine the role of higher education in opening up equal opportunity for mobility in American society--or in reinforcing the segregation between white and nonwhite America. It provides insight for how institutions, states, and the country should be thinking about U.S. Supreme Court Justice Sandra Day O’Connor’s hope that affirmative action will no longer be needed in 25 years.

Para ello se identifican las características que, según el autor, configuran el estado de naturaleza del hombre, como son la libertad, la igualdad, la vida, la relación con Dios. Se analiza además, la actividad primordial y fundante del estado de naturaleza como (...) es la actividad económica que a partir del trabajo, conduce a la propiedad y al mercado. (shrink)

En este trabajo se define formamente el concepto de representacion en química utilizando homomorfismos desde estructuras algebraicas, que llamamos sistemas de tipo C, en otras estructuras especiales de símbolos muy relacionados con los que son habituales en la qímica experimental. Para la definicion de los sistemas de tipo C se ha seleccionado un conjunto minimo de relaciones y funciones, que son necesarias para expresar proposiciones significativas en química. Tambien se define un lenguaje formal de primer orden adecuado a los sistemas (...) de tipo C, que llamamos L(C). EI resultado principal que se demuestra es que toda representación que verifica las mismas sentencias de L(C) que un sistema de tipo C, es necesariamente isomorfo a él. Se concluye por lo tanto que puede existir un problema linguístico subyacente en la aplicacion que de la mecaníca cuántica se hace en la química teórica.The concept of representation in chemistry bas been formallv defined by means of homomorphisms from algebraical structures, which we call type-C systems, to some special sets of symbols which can be related to the symbols ordinarily used in experimental chemistry. A minimum number of relations and functions, which would suffice to express significant propositions in chemistry, have been chosen to define type-C systems. A first order formal language L(C) adequate to type-C systems has been defined. It has been shown that each representation that verifies the same sentences of L(C) as a type-C system is necessarily isomorphic to it. It is concluded that a systematic study of the representation problem in chemistry is in order because a deep language problem underlies the application of quantum mechanies to chemical problems.

Within medical education, there is an increasing need to provide ethics education for learners embarking on service learning. The concept of hospitality, as illustrated in Homer’s classic epic the Odyssey, has the potential to underpin such ethics education. This paper describes the implementation and evaluation of an ethics education session for medical students, built on the concept of hospitality, before they embark on a three-year longitudinal service-learning home visit program. In preparation for their household visits, second-year students at a medical (...) school in Miami, Florida, participate in weekly didactic sessions. One of these classes consisted of a two-hour ethics session, involving a brief introductory large-group lecture, followed by self-administered small-group discussions of a series of case scenarios. An innovative web-based platform called Rise allowed the students to run their own small group activities. To assess the impact on the students’ ability to identify, and on their confidence in handling, ethical dilemmas, we administered pre- and post-session surveys. Students indicated statistically significant improvement in median responses to all questions, for two consecutive years. Students also listed three adjectives, both before and after the session, that they associated with good and bad hosts and guests. The consistency of the terms listed suggests that hospitality is a robust concept for the learners. In our experience, the concept of hospitality provides a robust framework for the students, and the mixed large-group and self-facilitated small-group format offers a valuable tool for ethics education related to service learning in medicine. Our study supports the utility of the concept as a teaching tool, and the format facilitates a session using minimal faculty. The notion of hospitality seems particularly fruitful for various ethical considerations in medicine, even beyond those that involve home visits. (shrink)

Este artículo plantea que ciertas situaciones en las que nos vemos obligados a prestar atención a los riesgos que tomamos al confiar, como la amenaza de violencia o la ruptura de la confianza, motivan una forma particular de confianza en la cual nos interesa tomar consciencia de las creencias, valoraciones e intenciones prácticas implicadas al confiar. Tras describir fenomenológicamente, desde una perspectiva husserliana, la estructura de esta forma de confianza, denominada confianza reflexiva o racional, se expone por qué su análisis (...) filosófico puede contruibuir a aclarar problemáticas epistemológicas y éticas que se desprenden del carácter social de nuestra existencia. En la parte final del artículo se sugiere que el concepto de confianza reflexiva o racional puede servir para entender problemáticas relacionadas con la posverdad y para discernir algunas formas básicas de dominación y de complicidad con la dominación.
