Este trabajo pretende hacer una terapia, propia de la metodología sugerida por el segundo Wittgenstein, respecto de la visión que sostiene a la creencia religiosa como una creencia cuyo contenido es empírico, proponiendo que dicha visión debe ser disuelta y dando como posibilidad en cambio una nueva analogía que lleve a su comprensión a través de contextos de esperanza.

Even though antenatal care is universally regarded as important, determinants of demand for antenatal care have not been widely studied. Evidence concerning which and how socioeconomic conditions influence whether a pregnant woman attends or not at least one antenatal consultation or how these factors affect the absences to antenatal consultations is very limited. In order to generate this evidence, a two-stage analysis was performed with data from the Demographic and Health Survey carried out by Profamilia in Colombia during 2005. The first stage was run as a logit model showing the marginal effects on the probability of attending the first visit and an ordinary least squares model was performed for the second stage. It was found that mothers living in the pacific region as well as young mothers seem to have a lower probability of attending the first visit but these factors are not related to the number of absences to antenatal consultation once the first visit has been achieved. The effect of health insurance was surprising because of the differing effects that the health insurers showed. Some familiar and personal conditions such as willingness to have the last children and number of previous children, demonstrated to be important in the determination of demand. The effect of mother’s educational attainment was proved as important whereas the father’s educational achievement was not. This paper provides some elements for policy making in order to increase the demand inducement of antenatal care, as well as stimulating research on demand for specific issues on health.

ABSTRACT In this paper we use economic cartoons that were published in the leading Colombian newspaper -El Tiempo-between 1928 and 1937,as a valid primary source for analysis of the tensionsand economic situations lived in Colombia during a tough worldwide economic period. Through economic cartoon it is possible to observe the perception of public opinion on economic policies and the fear and uncertainty that these were having on ordinary people. This document is part of a larger analysis that used economic cartoons as a source for examining Colombian economic history.

L'activitat professional és fonamental en la vida de qualsevol persona i en el cas de les persones amb discapacitat resulta molt potent per tal que assumeixin la identitat adulta. Per això, en la tesi es realitza una aproximació al binomi discapacitat i treball i a les mesures que justifiquen l'actual situació de la inserció laboral de les persones amb discapacitat al mercat laboral protegit i al mercat laboral ordinari. L'objectiu general de la tesi és conèixer en profunditat una experiència d'inserció laboral de persones amb discapacitat psíquica a l'Administració de la Generalitat de Catalunya. La investigació realitzada s'ha estructurat en dues fases. En la primera fase s'ha fet una anàlisi descriptiva del col·lectiu estudiat i en la segona fase, emmarcada en una perspectiva metodològica qualitativa, s'ha desenvolupat un estudi de casos per tal de mostrar el testimoni dels protagonistes, partir del seu relat i recollir les seves valoracions.

Aquesta tesi estudia com estimar la distribució de les variables regionalitzades l'espai mostral i l'escala de les quals admeten una estructura d'espai Euclidià. Apliquem el principi del treball en coordenades: triem una base ortonormal, fem estadística sobre les coordenades de les dades, i apliquem els output a la base per tal de recuperar un resultat en el mateix espai original. Aplicant-ho a les variables regionalitzades, obtenim una aproximació única consistent, que generalitza les conegudes propietats de les tècniques de kriging a diversos espais mostrals: dades reals, positives o composicionals (vectors de components positives amb suma constant) són tractades com casos particulars. D'aquesta manera, es generalitza la geostadística lineal, i s'ofereix solucions a coneguts problemes de la no-lineal, tot adaptant la mesura i els criteris de representativitat (i.e., mitjanes) a les dades tractades. L'estimador per a dades positives coincideix amb una mitjana geomètrica ponderada, equivalent a l'estimació de la mediana, sense cap dels problemes del clàssic kriging lognormal. El cas composicional ofereix solucions equivalents, però a més permet estimar vectors de probabilitat multinomial. Amb una aproximació bayesiana preliminar, el kriging de composicions esdevé també una alternativa consistent al kriging indicador. Aquesta tècnica s'empra per estimar funcions de probabilitat de variables qualsevol, malgrat que sovint ofereix estimacions negatives, cosa que s'evita amb l'alternativa proposada. La utilitat d'aquest conjunt de tècniques es comprova estudiant la contaminació per amoníac a una estació de control automàtic de la qualitat de l'aigua de la conca de la Tordera, i es conclou que només fent servir les tècniques proposades hom pot detectar en quins instants l'amoni es transforma en amoníac en una concentració superior a la legalment permesa.

RESUMO: Estamos a vivenciar dois fatos paradoxais: de um lado, uma organização da escola instituída que gera a autoconservação das práticas do professor e, do outro, tendências nos plano científico e do discurso político que apelam ao retorno ao ator - que reconhece o professor como sujeito de seu saber e fazer. Foi neste contexto que se realizou a pesquisa subjacente a esta tese sobre a formação docente num projeto de escolarização que se fundamenta numa perspetiva de educação popular contra-hegemónica, edificada, no Brasil, como ‗educação do campo‘. Buscou-se compreender a vivência docente, suas perceções e aprendizagens. Desenvolveu-se a investigação a partir das questões: é possível, no contexto atual de mudanças sociais direcionadas ao processo cada vez maior de individuação docente, a formação em democracia participativa numa experiência de educação popular? Como ela se estabelece? O que ela nos ensina? A metodologia assentou na observação participativa das reuniões de planeamento, avaliação e replaneamento dos(as) professores(as) e coordenadores, numa proposta local de educação do campo - do Programa Nacional de Educação na Reforma agrária. As reuniões e escolarização ocorreram em Ilhéus/Bahia/Brasil, durante os anos de 2005-2006. As referências teóricas para a análise empírica do material coletado foram: a perspetiva da reflexão-ação emancipatória de Carr e Kemmis (1998), que compreende as instituições educacionais criadas por pressões sociais e políticas; e a conceção de emancipação desenvolvida por Freire e por Habermas, assente na ação comunicativa/dialógica. Para a análise utilizou-se o método da Análise Crítica de Discurso (ACD), cuja principal referência foi Fairclough. Nas narrativas das reuniões percebeu-se o desenvolvimento de uma polidez positiva – atos de fala que demonstram o falante desejando estabelecer o consenso com ouvinte; assinalada por estruturas modais que direcionaram para a abertura de relacionamento e participação mútua entre professores(as) e coordenadores do projeto. O conteúdo manifesto das falas amparou-se numa perspetiva de educador que se constrói na prática, e, ao mesmo tempo, a constrói, mas que, entretanto, necessita de aportes teóricos críticos no processo de embate epistémico entre os saberes da vida quotidiana concreta e os saberes científicos. A função interpessoal foi expressa pela arquitetura dialógica, permitindo um processo de construção mútua de escola e professores(as). Pode-se afirmar que a prática analisada indica que nestes tempos, de controlo intenso das instituições escolares, de competição, de solidão, é obviamente necessária a organização coletiva de professores (as), de movimentos sociais e universidades, amparados e financiados por ordenamentos legais (conquistados pela população), para consolidar e ampliar projetos críticos de escolarização, mudando, reciprocamente, escolas e professores(as). ABSTRACT: We are experiencing two paradoxical facts: the organization of the established school which generates the self-preservation of teaching practices and, on the other hand, there is a political and scientific trend that claims the return of the ―actor‖ – the teacher being the subject of his knowledge and actions. It was therefore in this context, that the underlying research for this Thesis was conducted. It concerns to the teacher training in an educational project which is based on the perspective of a counter-hegemonic and popular education available to people at the Brazilian countryside – also called ―Field Education‖. We searched the understanding of the educational experience, its perceptions and learning. The investigation was developed from two fundamental questions: Is it possible to have the experience of a popular education system in a functioning democracy, at the light of the recent social changes that lead to a greater individuation? How is it established? What can we learn from it? The methodology was settled on the participant observation of the planning and evaluation meetings of teachers and coordinators of the National Education Program in the Land Reform in Brazil. These meetings occurred in Ilheús- Bahia- Brazil during the years of 2005-2006. The theoretical references to the empirical analyses of the material collected were: the perspective of the reflection – action emancipative of Carr & Kemmis (1998), which comprehends the educational institutions created by social and political pressures; and the conception of emancipation developed by Freire and Habermas, which is settled on the communicative-dialogical action. For the analysis it was elected the method of Critical Analysis of Discourse (CAD),which main reference was Fairclough. During the account of the meetings it was noticed the development of a positive politeness – which reveals the desire of the speaker to reach an agreement with the listener, signalized by modal structures that directed to an open and participative relationship between teachers and coordinators of the project. The manifest content of the speeches was sustained by the educator perspective, which is built on the daily practice. However, it needs some basic theoretical contributions to the epistemic struggle between concrete ordinary life and the scientific knowledge. The interpersonal function was expressed by dialogical architecture, allowing a mutual process of construction that involves the school and the teachers. The practice analyzed indicates that, more than ever, due to the massive control of the institutions, the extreme competition and solitude, the collective organization of the teachers, the social movements and the universities is necessary. They should be supported and financed by legal systems to consolidated and amplify important education projects, bringing necessary changes for schools and teachers reciprocally.

The Lisbon Treaty introduced changes to the ordinary revision process of EU Treaties. Article 48(3) TEU (Treaty of European Union) included the possibility of the President of the European Council summoning a Convention to analyse the projects to be revised and to adopt, by consensus, a recommendation to be put before the Intergovernmental Conference which would define the changes being introduced into the Treaties. This present work seeks to clarify the principal characteristics of this new stage in the revision process of EU Treaties. The main objective of this study is to set out how and why this new procedure evolved, how it works and what is new about what it brings to the revision process of the European Union.

Este ensayo plantea que la literatura latinoamericana actual abandona su propia esfera: de la ficción bien definida, de los claros requisitos de un texto para constituir «literatura», incluso de las clasificaciones en géneros. Esa esfera de «lo literario», amparada en reglas e instituciones, pierde consistencia, se limita entonces el poder y la capacidad de presión política que la literatura tuvo hasta hace pocas décadas. La actual literatura, finalizada la época de su autonomía, hablar de una vida moderna en la cual «todo lo cultural es económico» y donde «toda ficción es realidad» (y viceversa, en ambos casos). Lo cotidiano es ahora la vida, pero intervenida por las tecnologías de la información y la comunicación (que le prestan rasgos de virtualidad o de irrealidad). Se plantea con ellas el desafío de intentar una lectura desde otros parámetros, en caso contrario, se puede caer en la simpleza de calificarlas como no-literatura o «literatura mala».

Este estudio analiza las diversas posiciones asumidas por los indígenas frente a la Revolución de Quito de 1809. Siguiendo a dos personajes clave del Corregimiento de Riobamba, un cacique y un indio, busca las causas de la adhesión o del rechazo. Con ese propósito se estudian varias coyunturas que empiezan a mediados del siglo XVIII, desde las peticiones caciquiles y el posterior reacomodo de las autoridades indígenas efectuadas por los reformistas borbónicos, las continuas imposiciones tributarias y el terremoto de 1797, que desembocan en el levantamiento indígena de 1803. El artículo muestra una ruptura radical entre los indios del común y el pensamiento criollo fundador de la nación.

El concepto de servicio público, a pesar de las muchas polémicas que despierta en la doctrina, es una de las nociones que más interés despierta en los estudios del Derecho Administrativo. En efecto, se trata de una prestación técnica que satisface necesidades de carácter general, con sujeción a un régimen jurídico exorbitante del derecho ordinario. En tal virtud, como competencia de la Administración Pública, contribuye a la realización de los cometidos estatales y de los fines públicos. El presente trabajo aborda los principales aspectos que rodean a la temática del servicio público, de modo que brinda una introducción sumamente útil sobre la materia.

This article studies the impacts of the independence war in the regional border of the High Negro River, taking as it’s object of analysis the existing multiples connections between the inhabitants of both sides of the imaginary boundary line. From July 1817, the independence war in Venezuela changed the coordinates: the struggles between the republican patriots and those obedient to the King (Realistas), faithful to the restoration of the Spanish monarchy of Fernando VII, managed the great border region, and influenced the political, social and local dynamics, mainly the existing cross-border relations between both, impacted the ordinary life of the local population and affected the diplomacy between the Portuguese and Spanish American authorities, those faithful to the King (Realistas) and patriots.

This special report analyses legislative activity in the European Union and coalition formation in the European Parliament (EP) during the first half of the 7th legislative term, 2009-14. Co-decision is now the ordinary legislative procedure, not by name only: it was deployed on 90% of new proposals in 2010 and 86% in 2011, which suggests that the EP is now more influential than ever. There are differences in the degree of empowerment across committees, however. This report looks at the legislative workload of selected committees as an indicator of change in their influence, identifying which of them won and which lost out in terms of the quantity and type of legislation they tackle.

The variogram is essential for local estimation and mapping of any variable by kriging. The variogram itself must usually be estimated from sample data. The sampling density is a compromise between precision and cost, but it must be sufficiently dense to encompass the principal spatial sources of variance. A nested, multi-stage, sampling with separating distances increasing in geometric progression from stage to stage will do that. The data may then be analyzed by a hierarchical analysis of variance to estimate the components of variance for every stage, and hence lag. By accumulating the components starting from the shortest lag one obtains a rough variogram for modest effort. For balanced designs the analysis of variance is optimal; for unbalanced ones, however, these estimators are not necessarily the best, and the analysis by residual maximum likelihood (REML) will usually be preferable. The paper summarizes the underlying theory and illustrates its application with data from three surveys, one in which the design had four stages and was balanced and two implemented with unbalanced designs to economize when there were more stages. A Fortran program is available for the analysis of variance, and code for the REML analysis is listed in the paper. (c) 2005 Elsevier Ltd. All rights reserved.

The Representative Soil Sampling Scheme (RSSS) has monitored the soil of agricultural land in England and Wales since 1969. Here we describe the first spatial analysis of the data from these surveys using geostatistics. Four years of data (1971, 1981, 1991 and 2001) were chosen to examine the nutrient (available K, Mg and P) and pH status of the soil. At each farm, four fields were sampled; however, for the earlier years, coordinates were available for the farm only and not for each field. The averaged data for each farm were used for spatial analysis and the variograms showed spatial structure even with the smaller sample size. These variograms provide a reasonable summary of the larger scale of variation identified from the data of the more intensively sampled National Soil Inventory. Maps of kriged predictions of K generally show larger values in the central and southeastern areas (above 200 mg L-1) and an increase in values in the west over time, whereas Mg is fairly stable over time. The kriged predictions of P show a decline over time, particularly in the east, and those of pH show an increase in the east over time. Disjunctive kriging was used to examine temporal changes in available P using probabilities less than given thresholds of this element. The RSSS was not designed for spatial analysis, but the results show that the data from these surveys are suitable for this purpose. The results of the spatial analysis, together with those of the statistical analyses, provide a comprehensive view of the RSSS database as a basis for monitoring the soil. These data should be taken into account when future national soil monitoring schemes are designed.
