Se describe la subasociación Rosmarino-Cistetum ladaniferi cistetosum cyprii. que representa el ecótono entre Rosmarino-Cistetum ladaniferi y Santolino-Cistetum laurifolii. La ecología del nuevo sintaxon se ha estudiado seleccionando dos grupos de parcelas que comprenden representantes de las tres unidades fítosociológicas, y sobre las que se han efectuado medidas de temperatura y humedad edáficas bajo la cubierta vegetal a lo largo del año, así como de distintos aspectos microclimáticos a lo largo de un día tipo. El carácter de transición de la nueva subasociación ha quedado puesto de manifiesto tanto para el factor térmico como hídrico.

During twao years soil and litter pH of 31 permanent plots grown by several rock-rose scrubs (jarales) of Cistion laurifolii at different dynamic stages have been measured. Acidily records show the existence of important seasonal variations and according to a certain rythm. The different syntaxa are characterized as for this ecological factor and the results for these matorrals are compared with other data of heath-scrubs. Adult jaral-phases tend to decrease soil pH when compared with younger dwarf-scrubs-phases, nevertheless upper soil levels generally remain less acidic. Multivariable analysis do not show preference of t he different syntaxa for a certain soil-pH range.

Este estudio intenta esclarecer las transformaciones físicas y socioeconómicas de los asentamientos rurales de la región española de Castilla y León, durante la segunda mitad del siglo XX. Se analiza la evolución temporal de la forma urbana a través de un Sistema de Información Geográfico (SIG), calculando unos índices métricos y comparándolos con la información demográfica histórica. Los resultados pretenden mostrar los efectos de la especialización funcional económica, causada por la integración en las jerarquías productivas globales, sobre la estructura urbana. La pérdida gradual de las características tradicionales de los pueblos castellanos, como la compacidad y la integración en el entorno, debido a la pérdida o degradación de la arquitectura popular y la construcción de nuevas edificaciones industriales, supone un riesgo para las futuras políticas de desarrollo local. Se considera necesario preservar la identidad paisajística y evitar la destrucción del patrimonio cultural para poder revitalizar estos territorios.

This article has been written with the intention of being able to analyse the contributions of art —theatre, in this case— to the practice of social work. For this purpose, we have chosen to read the social reality in which we intervene through the lens of social constructionism. This helps us to rescue the social and subjective side of art, and, moreover, to recover the depathologization of the subject in professional intervention. Thus, using a practical case taken from work with adolescents in the German FSJ programme, hand-in-hand with a young girl called Anja we trace the developmental and sociological aspects of adolescence in order to later address certain common points of art and psychosocial work. Art will hence be redefined as a transitional object allowing questions to be addressed relating to (self-) perception, attachment, communication and changes in conduct as the ultimate goal of professional action. Lastly, we note the limitations and risks of art-based intervention, in order to conclude with a final synopsis.

Los cambios sufridos por los modelos de comunicación científica hacen que las bibliotecas universitarias se vean obligadas a dar nuevos servicios. Para adecuarse al investigador los bibliotecarios están desarrollando habilidades, colaborando con cada vez más estamentos y sustentando el acceso abierto. Apoyándose en una lista de posibles servicios, basada en la literatura especializada, este trabajo pretende cuantificar y evaluar el apoyo a la investigación desde las bibliotecas universitarias españolas. El sondeo demuestra la aparición de nuevos servicios e infraestructuras. Pero estas asistencias no suelen sistematizarse, difundirse ni evaluarse. Y, por otra parte, las consecuentes inversiones en personal y TIC han generado una brecha entre universidades

The origins of Sephardic press date back to the mid-20th century, when the influence of the Western world spread across the Sephardim communities of the East. The content of these newspapers was diverse: pieces of general interest, but also scientific, literary and humorous works, with various political orientations. These papers were published in different languages, writing styles and alphabets. Those to be analysed here, however, were published in aljamiado Judeo-Spanish: three papers from Smyrna and one from Salonica. Throughout this work we will focus on the different obstacles and difficulties the editors and publishers of this Ottoman Sephardic press had to face to bring their publications to light.

This paper presents and analyzes the first literary-journalistic chronicle writen and published by Miguel Hernández: “Defensa de Madrid. Madrid y las ciudades de Retaguardia”, during the Spanish Civil War (1936-1939). This chronicle is the first one of a series establishing a new and personal type of journalism: literary chronicles –poetical and political-. Miguel Hernandez published his masterpieces in different newspapers as a war reporter, with his own name and with a pen-name, playing roles of director and political commissar in different newspapers in the war-trenches. Thematically, this first article shows his personal and political engagement, as well as his desire and strategy to protect the capital city of Spain: Madrid. Methodologically, the analysis is an approached to linguistics in social sciences, which presents some of the personal characteristics and style of the chronist Miguel Hernández. Thus, it becomes patent that the so-called New Journalism (narrative and literary), which flourished in the 70s, had already been deeply and efficiently practiced by Miguel Hernández 40 years before. That is the reason why Miguel Hernández deserves to be added to the well-known collective of chronicle writers that have already been rescued to this moment. His literary style and quality are installing him in a outstanding position as well as pioneer of the genre nowadays known as New Journalism that in his case, it is politically engaged

The transition from a positivist matrix to an idealistic one in Argentinean academic philosophy can be read as a result of a gradual and problematic pollution. It was, also, heavily traversed by considerations that exceeded the theoretical aspects. Based on the willingness to explore this transit, the article pays attention to one of the episodes of this contamination: how the Revista de Filosofía reads Croce and Gentile’s philosophy. Observing there some possibility of dialogue between positivist assumptions, with which the journal takes a position, and the idealism the article analyze how this dialogue and its limits were given from a political consideration. If the idealism was condemned, it is centrally owed to its performance during the first years of the government of Mussolini. If, meanwhile, it was some to rescue of that philosophy, it was that it contributed to think the revolutionary change.

Chronic pain, without any organic or physical cause (DC), which in psycho-medical terminology is known as fi bromyalgia, (FM), is diagnosed each year to a considerable number of women in capitalistic societies. Our main interest in the following paper is to go in depth in the elaboration of this symptom, its treatment and the psychosocial effects, both in the social order as well as in the lives of the people who suffer from it. Our main goal in the following paper is to look deeper in the elaboration (conceptualization) of this symptom, its treatment and psychological affects, both in the social order as well as in the lives of the people who suffer from it, we are using linked speeches in Spanish magazines publications. The result has been the emergence of three hegemonic discourse positions: One position “scientist”, one “therapeutic of the conformity” position and one “economic and legalistic” position. Each of these has a specifi c feature, but on the whole, is enhanced, producing effects such as the absence of social context to explain the disease; disregard of gender differences in the management and treatment; the instrumentalization of pain to legitimize their practices and the subjection of women to the “psycho-biomedical” paradigm. In that way, a new signifi cance and politicization of the concept of pain is proposed.
