Biomonitoring of air pollutants by using lichens (Evernia prunastri) in areas between Kenitra and Mohammedia cities in Morocco.

In this study, Evernia prunastri, a lichen growing in its natural habitat in Morocco was analysed for the concentration of five heavy metals (Fe, Pb, Zn, Cu and Cr) from eleven sites between Kenitra and Mohammedia cities. The control site was Dar Essalam, an isolated area with low traffic density and dense vegetation. In the investigated areas, the concentration of heavy metals was correlated with vehicular traffic, industrial activity and urbanization. The total metal concentration was highest in Sidi Yahya, followed by Mohammedia and Bouznika. The coefficient of variation was higher for Pb and lower for Cu, Zn and Fe. The concentrations of most heavy metals in the thalli differed significantly between sites (p<0.01). Principal component analysis (PCA) revealed a significant correlation between heavy metal accumulation and atmospheric purity index. This study demonstrated also that the factors most strongly affecting the lichen flora were traffic density, the petroleum industry and paper factories in these areas. Overall, these results suggest that the index of atmospheric purity and assessment of heavy metals in lichen thalli are good indicators of the air quality at the studied sites.

Modelos de desarrollo, unificaci��n y ���desterritorializaci��n���.

El presente estudio tiene el objetivo de ofrecer una visi��n general sobre los Modelos de Desarrollo y Organizaci��n Territorial desde la perspectiva de las relaciones entre el medio urbano, ���rururbano��� y rural, en Espa��a. Para ello, tras conocer y valorar los enfoque conceptuales y tem��ticos, se estudia el crecimiento urbano en nuestro pa��s en las ��ltimas d��cadas, analizando de manera pormenorizada la importancia que ha cobrado y cobra la aplicaci��n legislativa de leyes, planes y normas, tanto en el propio crecimiento urbano como en la demanda de viviendas en las ciudades espa��olas y, de igual modo, la vinculaci��n de ambas con el precio de las viviendas, relacion��ndolo con la problem��tica de la ���rururbanizaci��n���, y del medio rural.

The emotional structure of the advertising message in radio

Radio advertising is suffering from a remarkable crisis of creativity as it has yet not found its role in a radio model based on voice locution and information genres. This article suggests the need for implementing a peripheral or heuristic strategy to attract and hold listeners��� attention. Within this framework, the narration and scene representation are proposed as suitable persuasion techniques. The objective is to design a useful conceptual tool for an efficient creative conception of narration at the service of certain commercial strategy. First, the concept of narrative persuasion is grounded according to the possibilities of the sound code. Second, the keys of scene representation and commercial strategy (brand, product, advantage, benefit and target) within the sound message are presented. And third, these keys are articulated in a model. This model is pre-tested by means of analyzing eight different case-radio ads.

La existencia de necesidades de informaci��n y comportamiento informativo en los entrenadores en deportes de combate

Este trabajo tiene como prop��sito esencial, realizar un acercamiento para detectar e identificar las necesidades de informaci��n y el comportamiento informativo de entrenadores en deportes de combate. Para ello se aplic�� un cuestionario a instructores de aikido, boxeo, esgrima, judo, karate, kendo, lima lama, lucha y taekwondo seleccionados mediante un muestreo no probabil��stico por causalidad. En general encontramos que los principales temas de inter��s entre los instructores son: los programas de entrenamiento, nutrici��n y dietas de entrenamiento. Por otra parte, los entrenadores son m��s propensos a utilizar su experiencia, internet y cursos para obtener informaci��n. En contraste se nota que la biblioteca y los libros son poco usados.

Una revisi��n de la Cadena Datos-Informaci��n-Conocimiento desde el Pragmatismo de Peirce

La Cadena Datos-Informaci��n-Conocimiento (DIC), denominada ���Jerarqu��a de la Informaci��n��� o ���Pir��mide del Conocimiento���, es uno de los modelos m��s importantes en la Gesti��n de la Informaci��n y la Gesti��n del Conocimiento. Por lo general, la estructuraci��n de la cadena se ha ido definiendo como una arquitectura en la que cada elemento se levanta sobre el elemento inmediatamente inferior; sin embargo no existe un consenso en la definici��n de los elementos, ni acerca de los procesos que transforman un elemento de un nivel a uno del siguiente nivel. En este art��culo se realiza una revisi��n de la Cadena Datos-Informaci��n-Conocimiento examinando las definiciones m��s relevantes sobre sus elementos y sobre su articulaci��n en la literatura, para sintetizar las acepciones m��s comunes. Se analizan los elementos de la Cadena DIC desde la semi��tica de Peirce; enfoque que nos permite aclarar los significados e identificar las diferencias, las relaciones y los roles que desempe��an en la cadena desde el punto de vista del pragmatismo. Finalmente se propone una definici��n de la Cadena DIC apoyada en las categor��as tri��dicas de signos y la semiosis ilimitada de Peirce, los niveles de sistemas de signos de Stamper y las met��foras de Zeleny.

Cine polic��aco del tardofranquismo: El thriller en el ���Per��odo Oscuro��� del cine espa��ol (1969-1975)

Definici��n de la etapa de crisis del aparato cinematogr��fico franquista, llamada aqu�� ���Per��odo Oscuro��� (1969-1975), discusi��n de la etiqueta de subg��neros aplicada al cinema bis de la ��poca, y caracterizaci��n hist��rica del thriller espa��ol y de sus corrientes est��ticas y conceptuales internas en dicho per��odo.

The first chronicle of Miguel Hernandez: The New Journalism (1936-1939)

This paper presents and analyzes the first literary-journalistic chronicle writen and published by Miguel Hern��ndez: ���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 Hern��ndez. 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 Hern��ndez 40 years before. That is the reason why Miguel Hern��ndez 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 trade unions membership dynamics and union members��� trajectories

This text presents an analysis of aggregated membership���s dynamics for Spanish trade unions, using ECVT data, as well as union memberships��� trajectories, or members��� decisions about joining the organization, permanency and responsibilities, and subsequent attrition. For the analysis of trajectories we make use of information of the records of actual memberships and the record of quitting of CCOO, and of a survey-questionnaire to a sample of leavers of the same union. This study allows us to confirm a linkage between the decision and motivations to become union member, to participate in union activities, the time of permanency, and the motives to quit the organization. We also identify five types of union members��� trajectories, indicating that, far from views that assert a monolithic structure, unions are complex organizations.

The proposal of democratic citizenship in Hannah Arendt

The main purpose of this paper is to analyze Hannah Arendt���s citizenship proposal. The central thesis is that this proposal is possible in contemporary democracies, and it is adequate for developing and strengthening of political action. The work is divided in five sections. In the first, we develop a brief introduction on the studied issue. In the second and third section, we analyze, respec-tively, political and moral conditions that enable democratic citizenship, and the conditions that hinder the exercise of the same, according to Arendt. Then, we reflect critically on Arendt���s citizenship proposal. Finally, we conclude and we propose a set of civic challenges relate to current democracies in light of the above proposal.

Discourses on Modernization in the Employment Public Services: Towards a New Form of Governance?

The ���crisis of the social issue��� in the EU has led to a certain consensus in the need to renew the organizational and institutional model of public administration. The core of the reform implies important administrative changes in most of the European welfare states. Those changes are inspired on theories such as the new public management, management by objectives or partnership. Such changes involve both semantic (���sharing responsibilities���, ���effective costs���, or the substitution of ���citizen under an administration��� by ���consumer���) and political (predominance of scattered forms of power and the individualization of responsibilities) transformations which operate in the framework of individuals and State relations. The paradigms of activation and flexicurity have been central in this public administration modernization project. This commitment with new forms of governance of social issues has important consequences for the political and moral foundations of social cohesion, and the Spanish case is not an exception. This paper aims at looking at those representations of ���modernization��� (as they appear in debates about the employment services restructuring policies) in detail as well as providing references to the trajectory of such reforms of public services since the early eighties to the beginning of the crisis.

Citizens��� attitudes toward public services. Satisfaction in 2009-2011

The aim of this paper is to study the recent changes on citizens��� satisfaction with the performance ofpublic services, in the period 2009-2011 in Spain. Using data from the surveys on Quality of PublicServices, developed by the Sociological Research Center jointly with the National Agency for theEvaluation of Public Services and Quality of Services, our results show that the level of satisfactionhas slightly increased, which seems to display a greater tendency to positively value public servicesduring economic retrenchment. A major determinant of high satisfaction is self-reported ideology.Besides, immigrants display higher levels of satisfaction than Spaniards.
