Se expone asimismo la tipología de sus ideas principales elaborada por Norbert Hinske y se hace balance acerca de su posible vigencia e interés para la actualidad, con atención especial a la idea de una razón humana universal y de la destinación del ser humano.

Resumen. En el presente análisis se exponen las bases del clásico debate entre Richard Clark y Robert Kozma, autores reconocidos en el campo de Tecnología Instruccional y la Educación a Distancia por la relevancia de sus aportaciones; a partir del argumento inicial presentado por Richard Clark en 1983 contenido en su artículo denominado Reconsidering research on learning from media; dónde describe evidencias suficientes que apoyan su opinión respecto a que los medios instruccionales no ejercen influencia alguna en el nivel de (...) aprovechamiento de los estudiantes durante el proceso de enseñanza-aprendizaje.Palabras claves. Tecnología instruccional, educación a distancia, medios, aprendizaje, enseñanza.. This analysis sets out the basis of the classic debate between Richard Clark and Robert Kozma, known authors in the field of Instructional Technology and Distance Education for the relevance of their contributions, from the initial argument presented by Richard Clark in 1983 contained in his article entitled Reconsidering research on learning from media; in which he describes sufficient evidences supporting his opinion that instructional media have no influence on the level of student achievement in the teaching-learning process.Keywords. Instructional technology, distance education, media, learning, teaching. (shrink)

The notion of “individuality” in Plotinus is one of the most discussed. Throughout the Enneads, the problem of the individual subject arises from the complexity in understanding the relation between man and soul. To the intelligible man, also known as the inner or first man, a second man is added, so that “we have come to be the pair of them” 14.28-30). This question has been extensively addressed from different angles that lead either to a purely structuralist solution, or to (...) its criticism and the search for a more stable definition of subjective identity. The thesis that we will defend in this article, and that will indicate our position in the debate, tries to give a new perspective of the issue alluding to the sphere of life and its forms. The continuity between the different men will be determined by the continuity between their different forms of life, a primary issue to which the problem of individuality and the different modes of consciousness are subject.

This essay presents the early days of human cytogenetics, from the late 1950s until the mid 1970s, as a historical series of images. I propose a chronology moving from photographs of bodies to chromosome sets, to be joined by ultrasound images, which provided a return to bodies, by then focused on the unborn. Images carried ontological significance and, as I will argue, are principal characters in the history of human cytogenetics. Inspired by the historiography of heredity and genetics, studies on (...) visual cultures, the conceptualization of circulation, and the sociology of pregnancy, I suggest that cytogenetics, through its focus on pregnancy, pregnant women, and their offspring, found strategic living materials that stabilized human chromosome studies as a biomedical, post-eugenics practice. The historicity of each path displays a wide circulation of objects, tools, and methods that condensed on images that shared in the centuries-old visual expertise that medicine and botany had manufactured.

A political discourse of peace marked the distribution and use of radioisotopes in biomedical research and in medical diagnosis and therapy in the post-World War II period. This occurred during the era of expansion and strengthening of the United States' influence on the promotion of sciences and technologies in Europe as a collaborative effort, initially encouraged by the policies and budgetary distribution of the Marshall Plan. This article follows the importation of radioisotopes by two Spanish research groups, one in experimental (...) endocrinology and one in molecular biology. For both groups foreign funds were instrumental in the early establishment of their laboratories. The combination of funding and access to previously scarce radioisotopes helped position these groups at the forefront of research in Spain. (shrink)

The complexity of the epistemological framework developed in the philosophy of Iamblichus does not allow to be captured from the polarity that underlies the categories of rational and irrational. After the projection of such categories, the core of this philosophy remains itself misunderstood. In this paper we intend to point to the need for a hermeneutic that respects the Neoplatonism that, from their own internal assumptions, display models that allow open understanding about the meaning and coherence of this thought. A (...) serious approach to the texts foregrounds the importance of the method. This must accompany the complexity of its meaning without projecting beyond categories that hide their cores basic sense, attempting an inside their outlines. The deployment of this path indicates the result of the demonstration of the precariousness of certain exegetical lines that tend to hide behind the projection of conceptual parameters strangers, basic access key to this thought.

Las áreas rurales remotas en proceso de decrecimiento poblacional son altamente vulnerables y sensibles a los movimientos poblacionales, tanto a la salida como a la llegada de nueva población que engrose las cifras de la población local. El artículo explora el impacto que tuvo la crisis del 2008 en las migraciones prorrurales que se dirigían hacia este tipo de áreas rurales. Para ello se analiza el caso de la comarca de Las Batuecas-Sierra de Francia, en Salamanca. El trabajo de campo, (...) de naturaleza cualitativa, consiste en una serie de entrevistas semiestructuradas a informantes clave y nuevos residentes. El análisis permite observar el impacto de la crisis en un doble sentido: una migración forzada por la crisis como último recurso de supervivencia y una migración vinculada a aspiraciones de tipo medioambiental que encuentra en la crisis el impulso para poner en marcha un deseo que permanecía en estado latente.

From the mid-1960s onwards, a set of Spanish molecular biology research groups emerged in Spain. The factors contributing to this included: the return of a group of molecular biologists from their postdoctoral period abroad, the negotiations for the return of Spanish-born Nobel prize winner Severo Ochoa from New York, the negotiations for Spanish membership in the European Conference of Molecular Biology, and national policy towards university reform. As a result, the early molecular biologists’ research groups began to be recognised as (...) research schools by Spanish authorities and postgraduate courses and new research centres for molecular biology were set up. Foreign influence in the whole process was crucial. (shrink)

Se analizan en este artículo las características simbólicas del género en el espacio de lo sagrado. Para ello se realiza un estudio de la imagen del budismo que los publicistas vienen haciendo en los últimos tiempos. Oriente ha identificado virtudes como la compasión y la sabiduría con géneros que nuestro marco cultural ha cambiado por completo. Se ejemplifican las conclusiones con un breve análisis publicitario, que emplea imágenes, tanto visuales como narrativas, del budismo en un intento de proporcionar un valor (...) añadido a los productos publicitados. En el proceso de mostrar las virtudes “budistas” asociadas al producto, cambia el género de las mismas adaptándolas a nuestro modo occidental de entenderlas. (shrink)

El estudio del cine como medio para el análisis sociológico es poco frecuente todavía en nuestro país. Existen numerosos artículos analizando el cine desde diversos ángulos, también el femenino, especialmente roles como el de la mujer fatal en el cine negro. Pero es menos habitual emplear este formato como parte de un método analítico del que extraer un reflejo social de lo que las pantallas proyectan y, a un tiempo, contribuyen a legitimar como base de una sociedad futura. No obstante, (...) existen pocos medios que sean capaces de reflejar el gran cambio acaecido en la historia reciente de la sociedad española. Este interés documental incrementa su potencial al enfocar en primer plano a las mujeres. Este artículo es una contribución a estudiar un campo tan atractivo como es el cine de migraciones a través de la óptica de los imaginarios sociales. (shrink)

Alongside the renowned male pioneers of medical cytogenetics, many women participated in investigations at the laboratory bench and the bedside, both in Europe and the Americas. These women were committed to this new biological and clinical practice—cytogenetics, the origins of contemporary genetic diagnosis—and contributed to the creation of new biological concepts and settings centered on the study of chromosome imaging. This paper will review the contributions made by a group of woman scientists from a wide geographical distribution, situating their names (...) and research agendas within the history of a field dating back to early plant and insect cytogenetics. Rather than an exhaustive compendium of women geneticists, this essay presents a kind of historical reconstruction that can be achieved by placing women at center stage in their geographies and networks of circulating cytogenetic knowledge and practices thereby relating a history of genetic images though the work carried out by women, retrieving their agency and constructing an inclusive history of an influential contemporary biomedical practice as it gained increasing influence in the laboratory and the clinic.

En este artículo se repasan algunas de las líneas de investigación más influyentes en el área de los estudios sobre biología y género y libros publicados al respecto por un grupo creciente de autoras. Como es habitual entre los estudios de género, en este caso los referentes a la biología cuentan con estudios sobre investigadoras en el área de la biología, mujeres que participaron activamente en la generación de saberes y prácticas de esta disciplina, por una parte, y con trabajos (...) sobre los sesgos epistémicos de género y sobre el androcentrismo en el conocimiento biológico, por otra. La genealogía se relaciona con la autoridad y ésta con el género como agencia en las ciencias y las experimentaciones contemporáneas. (shrink)

This essay details a historical crossroad in biochemistry and microbiology in which penicillin was a co-agent. I narrate the trajectory of the bacterial cell wall as the precise target for antibiotic action. As a strategic object of research, the bacterial cell wall remained at the core of experimental practices, scientific narratives and research funding appeals throughout the antibiotic era. The research laboratory was dedicated to the search for new antibiotics while remaining the site at which the mode of action of (...) this new substance was investigated. This combination of circumstances made the bacterial wall an ontology in transit. As invisible as the bacterial wall was for clinical purposes, in the biological laboratory, cellular meaning in regard to the action of penicillin made the bacterial wall visible within both microbiology and biochemistry. As a border to be crossed, some components of the bacterial cell wall and the biochemical destruction produced by penicillin became known during the 1950s and 1960s. The cell wall was constructed piece by piece in a transatlantic circulation of methods, names, and images of the shape of the wall itself. From 1955 onwards, microbiologists and biochemists mobilized new names and associated conceptual meanings. The composition of this thin and rigid layer would account for its shape, growth and destruction. This paper presents a history of biochemical morphology: a chemistry of shape – the shape of bacteria, as provided by its wall – that accounted for biology, for life itself. While penicillin was being established as an industrially-manufactured object, it remained a scientific tool within the research laboratory, contributing to the circulation of further scientific objects.

This article exposes the neoplatonic element present in the metaphysics of causality elaborated in the seventeenth century by Leibniz. It explains this question in relation with medieval Neoplatonism, whose metaphysics of the Verb appears as the nucleus of the explanation of the relationship between causality and otherness.

The author extensively reviews Berciano's last book on Heidegger. Berciano is the spanish best known Specialist on Heidegger's metaphysics and anthropology.

Christian Wolff's understanding of Leibniz's monadology, framed out from his own underlying philosophical principles, had a definite and direct influence on the 18th century new elaboration of the "physical monad" theory.

The author explains, partly following Millán-Puelles' ideas, the mediaeval origin and meaning of the concepts of 'expressio' and 'repraesentatio', extensively used in -though not acknowledged by- Modern philosophy. After such review, the so called 'philosophy of expression' is shown as based on a modern inversion of such concepts.

En este breve escrito se pretende únicamente recordar algunas de las intuiciones fundamentales del pensamiento de Josef Pieper, intuiciones que han constituido sin duda una aportación única y original a la filosofía del siglo XX.

Según L. Polo la libertad es un trascendental de carácter donal; esa índole donal significa que se ejerce entendiendo y aceptando el don recibido. Se reconoce entonces que ser libre implica saberse uno mismo enteramente dependiente de Dios. Desde estas tesis mantenidas al final de La libertad trascendental, se expondrá la concepción poliana de la criatura en consonancia con esa condición de la libertad. Se mostrará que la teoría poliana acerca de la libertad así entendida encuentra algunos antecedentes en la (...) noción de libertad que fue desarrollada por Nicolás de Cusa en su doctrina acerca de la imagen; doctrina que entiende la libertad como posesión de sí en el autoconocimiento y profunda unión con la trascendencia.

Against the modern theory of representation, whiou makes the world opaque, Polo Suggests reviviting the classical theory of ilumination. Intentionality of knowledge, according to Polo, makes possibe the "deveiling" of reality, and shows its radical dependence from God.

We study twentieth-century biological sciences as experimental sciences by historically reconstructing the uses of experiments. Concepts like artificial, natural, and inventions, are handled so as to show how much current biological thought has been constructed on the basis of the invention of different kinds of experiments, instruments, and technical devices, experimental systems, and ideas concerning the fonctioning of nature. It is suggested that the frontier that may separate the natural from the artificial has already been crossed. Human intervention in the (...) natural phenomena through reproducible experiments hints to a view of current biological knowledge as a permanent invention of nature. (shrink)
