Los sabinares albares, debido a su carácter abierto y a la gran amplitud ecológica de Juniperus thurifera L. presentan problemas para un encuadre fitogeográfico preciso. En este trabajo se pretende un enfoque sintético del estudio de la vegetación y el medio basado en un proceso de inventariación extendido a los sabinares de la porción meridional del Sistema Ibérico (Albarracin, Gúdar. Javalambre) y apoyado en técnicas de análisis fitoecológico. Se trata esencialmente de mostrar que el reparto de los grupos ecológicos, definidos previamente por comparación de inventarios fitosociológicos y ecológicos, puede explicarse por las variaciones dle los factores medioambientales. incluyendo la intervención humana. Como resultado final se ha establecido una tipificación de estos sabinares fundamentada en análisis dc componentes principales y análisis factorial de correspondencias.

Hyperadrenocorticism is a rare endocrine disease in the cat; it is characterized by elevated blood cortisol level that generates numerous clinical signs including hyperglycemia, polyuria, polydipsia, polyphagia and skin diseases. The average age of onset is around 10 years. This disease usually occurs link with other endocrine disorders such as diabetes mellitus.The disease can be produced by functional alteration of the pituitary gland or the adrenal. A case report, with differential diagnosis and review of the literature, is presented.

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.

The Chilean Cooperative Sector (SCCh) can be explained as a human activity system of high complexity, which seeks to maintain an independent existence, in example, be viable. From this perspective, the Viable System Model (MSV) as conceptual reference presents a real opportunity to study the organization of the cooperative sector in Chile.The central objective of the work refers to study the feasibility of SCCh in a context of sectorial organization, considering the social, legal and economic fabric of the country today.To do this, supported by a systemic methodology were performed: a characterization of the problem situation of the sector -identifying some relevant factors in the areas of market structure, legal regulations and inter cooperation-an organizational diagnosis and proposed a set guidelines for its development.From the above it is concluded that there is relevance between the characteristics of the case study theoretical and methodological approach. The methodology takes tested in other organizational practices such as VIPLAN tools, and applies the SCCh. Its contribution in the field of study is oriented around a holistic view of the organization and promotion of their viability, thereby generating an approach that delivers specific sectorial development strategies, surpassing the approximation of descriptive characterization. Thus, we provide a diagnostic model of the Chilean Cooperative Sector and propose guidelines to support their organizational development.

The goal of this study is to identify cues for the cognitive process of attention in ancient Greek art, aiming to find confirmation of its possible use by ancient Greek audiences and artists. Evidence of cues that trigger attention’s psychological dispositions was searched through content analysis of image reproductions of ancient Greek sculpture and fine vase painting from the archaic to the Hellenistic period - ca. 7th -1st cent. BC. Through this analysis, it was possible to observe the presence of cues that trigger orientation to the work of art (i.e. amplification, contrast, emotional salience, simplification, symmetry), of a cue that triggers a disseminate attention to the parts of the work (i.e. distribution of elements) and of cues that activate selective attention to specific elements in the work of art (i.e. contrast of elements, salient color, central positioning of elements, composition regarding the flow of elements and significant objects). Results support the universality of those dispositions, probably connected with basic competencies that are hard-wired in the nervous system and in the cognitive processes.

En trabajos anteriores, hemos avanzado en la identificación y diferenciación de tres categorías de potencias: potencias mundiales, potencias medias y potencias regionales. Pero, más allá de las potencias mundiales y las potencias medias que se encuentran en el centro del sistema-mundial, y las potencias regionales que se ubican en la semiperiferia, ¿es posible hablar de potencias que se encuentren en la periferia? Como se trata de Estados periféricos, ¿pueden ser calificados como “potencias”? ¿En qué radicaría su relevancia y envergadura? Dichas “potencias” ¿pueden ser agrupadas en una nueva categoría? De ser así ¿qué características compartirían? El objetivo de este documento es proponer una nueva  categoría de potencias en el sistema internacional: las potencias subregionales.

This article explores forms of migrant families’ reorganization within a (new) global economic crisis and the hardening of migration control in Europe; based on the cases of Dominican and Brazilian migration to Spain.Our goal is not to characterize the wholeness of strategies from these collectives, instead visualize its heterogeneity. Displacement of Dominican and Brazilian population to Spain shares the role of women as the first link of migration chains. In both cases women are the economic support of transnational families and they lead reunification's processes. Nevertheless, differences in the time spent in the destination country, migratory status, origin (rural-urban), level of education, class and labor insertion in destination country, affect differently, the planning and start up of migration projects, the organization of care and family reunification strategies. These findings question the predominant place granted to national origin in the study of international migration.

Este artículo cuantifica la presencia de obra artística de mujeres artistas en 21 museos y centros de arte contemporáneo españoles. Los resultados constatan una nítida sub-representación de la obra exhibida, por debajo del 20 por ciento. ¿Por qué sucede esto?, ¿diferencial potencial artístico de mujeres y hombres?, ¿superioridad masculina?, ¿discriminación? o ¿un sistema de arte con sesgo androcéntrico? En estas páginas se discute sobre la presencia de varios factores para explicar la brecha de género y se reclama, de las administraciones públicas y las instituciones de gestión cultural, el cumplimiento de la Ley para la Igualdad para garantizar la paridad.

Este estudo analiza como Manuel Rivas aproveita a ambigüidade do concepto de estereotipo para crear una identidade cultural galega. En Unha espía no Reino de Galicia (2004), Rivas propón que a imaxe paródica do galego e o conxunto de trazos estereotipados que se lle asignan non son un elemento alleo a cultura galega, senón que é un trazo integral da dialéctica da súa identidade nacional. Desta maneira, ó feito diferencial galego, ademais da lingua, a unidade territorial, o celtismo, ou a emigración, habería que engadir a capacidade do galego de parodiar o seu propio discurso nacional.

This article discusses the challenges of irregular migration for the security of the EU. They are analyzed starting with the European Security Strategy 2003, and the Report on its Implementation, 2008, and notes many failures: The EU Members did not follow the directives adopted in Brussels, the mismanagement of migration and asylum policies, and numerous actions that can be characterized or described as improvised, scattered or irresponsible. The 2016 Global Strategy recognizes these failures and call attention to the European leaders to reconsider how the EU functions and operates, suggesting the need for greater unity and cooperation to achieve a more effective migration policy. However, the article points out that practically all of the sections of the new Strategy dealing with migration were already embodied in previous Strategies, and stress that in parallel with the publication of the 2016 Global Strategy, actions are already undertaken, such as the EU readmission agreements signed with several important third countries of origin.
