Iconografía de la pobreza (siglo XII – siglo XX): la imagen de la pobreza en la ciudad de Madrid (2000-2010)

Hemos adoptado una definición sociológica de pobreza, que nos ha permitido elaborar una imagen del pobre como individuo ante la sociedad. El estado de la cuestión del que partimos está formado por las definiciones sintéticas de pobreza que ofrecen autores actuales (por ejemplo, pobreza absoluta-relativa, pobreza-desviación social, dualización social-pobreza de Tezanos; nueva pobreza-pobreza tradicional de Tortosa) a partir de las cuales comprendemos y contextualizamos a los autores canónicos de la pobreza en su época (Vives-Robles-Soto, Giginta-Herrera, Weber, Tocqueville, Bentham o Marx por poner algunos ejemplos clásicos). Objetivos de la tesis: Esta tesis pretende establecer una tipología que razone los significados de los iconos de pobreza en el diseño y arte madrileños del inicio del siglo XXI, entroncando esas imágenes de pobreza con la tradición iconográfica occidental del pauperismo. La caracterización del pobre, su posición social, sus atributos y escenarios mantienen una afinidad visual y conceptual con el presente (hemos situado imágenes separadas en el tiempo pero unidas por los ejes semánticos que planteamos y se comprueba sus puntos visuales). Hipótesis: Nuestra hipótesis de partida, que confirmamos al concluir la tesis es que existe una relación entre esas imágenes míseras y un concepto de riqueza y pobreza de honda raíz cultural. La descomposición iconográfica de las imágenes se combina con un análisis de campo semántico de los discursos que en cada época y autor acompaña los iconos de pobres. Metodología: Para analizar el corpus de más de 600 imágenes y 1000 discursos sobre la pobreza hemos empleado un protocolo común para poder establecer posteriores comparaciones. Nuestro método combina el análisis de discurso (Muñoz, Álvarez-Uría), con especial atención al empleo de metáforas (Lakoff, Lizcano), y el análisis iconográfico (Panofsky). Los epígrafes de este modelo de análisis son: datos de la época, teóricos que definen la pobreza, antecedentes de concepto de pobreza, metáfora sobre la pobreza, movilidad social: ser o estar pobre, legitimación social, políticas de la pobreza, número de pobres, tipos de pobres, pobreza y clase social, relación ricos pobres, aspecto y ejemplos del pobre, denominación del pobre, lugares de la pobreza, ceremonias de la pobreza y las imágenes artísticas y de diseño. Conclusiones: Hemos conseguido describir el significado de las imágenes artísticas y de diseño sobre la pobreza madrileñas en el principio del s. XXI elaborando una tipología semántica con seis definiciones de pobreza: pobreza ironizada, recreada, bella, fea, de lucha social y exótica. Damos cuenta de ejemplos paradigmáticos del presente para ilustrar cada tipo y relacionamos cada una de esas clases de pobreza con visiones de la pobreza tradicional.

Essays on Microeconometrics

My dissertation has three chapters which develop and apply microeconometric tech- niques to empirically relevant problems. All the chapters examines the robustness issues (e.g., measurement error and model misspecification) in the econometric anal- ysis. The first chapter studies the identifying power of an instrumental variable in the nonparametric heterogeneous treatment effect framework when a binary treat- ment variable is mismeasured and endogenous. I characterize the sharp identified set for the local average treatment effect under the following two assumptions: (1) the exclusion restriction of an instrument and (2) deterministic monotonicity of the true treatment variable in the instrument. The identification strategy allows for general measurement error. Notably, (i) the measurement error is nonclassical, (ii) it can be endogenous, and (iii) no assumptions are imposed on the marginal distribution of the measurement error, so that I do not need to assume the accuracy of the measure- ment. Based on the partial identification result, I provide a consistent confidence interval for the local average treatment effect with uniformly valid size control. I also show that the identification strategy can incorporate repeated measurements to narrow the identified set, even if the repeated measurements themselves are endoge- nous. Using the the National Longitudinal Study of the High School Class of 1972, I demonstrate that my new methodology can produce nontrivial bounds for the return to college attendance when attendance is mismeasured and endogenous.

The second chapter, which is a part of a coauthored project with Federico Bugni, considers the problem of inference in dynamic discrete choice problems when the structural model is locally misspecified. We consider two popular classes of estimators for dynamic discrete choice models: K-step maximum likelihood estimators (K-ML) and K-step minimum distance estimators (K-MD), where K denotes the number of policy iterations employed in the estimation problem. These estimator classes include popular estimators such as Rust (1987)’s nested fixed point estimator, Hotz and Miller (1993)’s conditional choice probability estimator, Aguirregabiria and Mira (2002)’s nested algorithm estimator, and Pesendorfer and Schmidt-Dengler (2008)’s least squares estimator. We derive and compare the asymptotic distributions of K- ML and K-MD estimators when the model is arbitrarily locally misspecified and we obtain three main results. In the absence of misspecification, Aguirregabiria and Mira (2002) show that all K-ML estimators are asymptotically equivalent regardless of the choice of K. Our first result shows that this finding extends to a locally misspecified model, regardless of the degree of local misspecification. As a second result, we show that an analogous result holds for all K-MD estimators, i.e., all K- MD estimator are asymptotically equivalent regardless of the choice of K. Our third and final result is to compare K-MD and K-ML estimators in terms of asymptotic mean squared error. Under local misspecification, the optimally weighted K-MD estimator depends on the unknown asymptotic bias and is no longer feasible. In turn, feasible K-MD estimators could have an asymptotic mean squared error that is higher or lower than that of the K-ML estimators. To demonstrate the relevance of our asymptotic analysis, we illustrate our findings using in a simulation exercise based on a misspecified version of Rust (1987) bus engine problem.

The last chapter investigates the causal effect of the Omnibus Budget Reconcil- iation Act of 1993, which caused the biggest change to the EITC in its history, on unemployment and labor force participation among single mothers. Unemployment and labor force participation are difficult to define for a few reasons, for example, be- cause of marginally attached workers. Instead of searching for the unique definition for each of these two concepts, this chapter bounds unemployment and labor force participation by observable variables and, as a result, considers various competing definitions of these two concepts simultaneously. This bounding strategy leads to partial identification of the treatment effect. The inference results depend on the construction of the bounds, but they imply positive effect on labor force participa- tion and negligible effect on unemployment. The results imply that the difference- in-difference result based on the BLS definition of unemployment can be misleading

due to misclassification of unemployment.

Formal evolution and content in Asturian newspapers. From World War One to the Primo de Rivera Dictatorship

Between 1914 and 1923, and in general during the 1910s and 1920s, important changes occurred in the Asturian press that can be seen, for example, in the type of dailies which achieved certain readership levels. The form and number of pages evolved, images became more common, so-called citizen journalism was more freely practised, and there was a trend -when there was an opportunity- towards publishing articles which involved the author travelling to distant lands. Simultaneously, the consideration of sport as a show and the treatment given to other content both helped outline a new media scenario.

Women’s football. Notes for a social history of women’s sport in Spain, 1900-1936

In the context of demands by the European feminist movement at the beginning of the 20th century, in Spain women’s sport flagged up aspirations to what were considered to be male practices. The first experiences of women in football stand out because of their use of the media to appear as a symbol of social transformation to modernity in the 20th century. It was not in vain that women’s football highlighted the demands of the feminist movements, although it did come up against male disapproval from an opposing group. The research sets out from a bibliographical and media review of specialist press and sports news of the time. Other current studies have also been considered in order to place it in a social and historical focus on sport. This has enabled us to highlight that football in Spain was established as an unequivocal space for (re) producing male hegemony where women were relegated to the representation of a symbolic ritual in a scenario of accessory and condescension.

La popularización del fútbol en España. Análisis del fenómeno a través de la literatura especializada del fútbol (1920-1936)

La consolidación del fútbol en España se produjo a partir de los años veinte del siglo pasado. Entre 1920 a 1936 el fútbol adquirió todos los rasgos personales que hoy le caracterizan. En esta época surgió una literatura técnica y periodística especializada que se configuró como uno de los pilares más importantes para el desarrollo técnico deportivo y del espectáculo de masas. En torno a esta cuestión, el presente artículo busca un doble objetivo: recopilar la literatura técnica y periodística especializada publicada durante el período de 1920 a 1936, y reconocer el alcance social, técnico e ideológico de esta literatura futbolística en el proceso de configuración del fútbol en España. Para abordar este propósito hemos utilizado una metodología heurística y de análisis documental de las fuentes originales. Apreciamos que a través de estas obras podemos conocer mejor el contexto del espacio socio-deportivo del fútbol en España y, también, despertar nuevas líneas potenciales de investigación.

Ultrastructural and Histological Study of Oogenesis and Oocyte Degeneration in the PenshellAtrina maura(Bivalvia: Pinnidae)

The successive stages of oogenesis and the changes involved in the oocyte degeneration process in the penshell Atrina maura were examined using light and transmission electron microscopy. The ovarian maturation process is asynchronous, as oocytes at different developmental stages can be found simultaneously. Oocytes develop from oogonia and then undergo three distinct stages of oogenesis: previtellogenesis, vitellogenesis and postvitellogenesis with mature oocytes. Atrina maura displays a solitary oogenesis type, in which follicular cells become associated with oocytes from the earliest stages of development and seem to play an integral role in vitellogenesis. The cytoplasm of vitellogenic oocytes contains numerous whorls of rough endoplasmic reticulum and Golgi bodies, suggesting that auto-synthetic vitellogenesis may occur in this species. In addition, the degeneration process of postvitellogenic oocytes triggered by a seasonal increase in water temperature (> 25°C) is described.

"Et occidetur virtute Domini Antichristus a Mikaele arcangelo". Paisaje y escatología en Sant Miquel de Llíria (s. XIV d. C.)

El presente articulo intenta determinar las razones por las que el santuario de Sant Miquel de Llíria, uno de los más importantes de la actual provincia de Valencia, se consagró al arcàngel guerrero. Se estudia para ello la historia de su culto en Occidente, haciendo hincapié en aspectos como su relación con los lugares elevados y la frecuente proximidad de sus santuarios con aquellos dedicados a la Virgen. Atenderemos también a aspectos fundamentales del contexto histórico, como los movimientos de renovación espiritual medievales, la influencia del médico y teólogo Arnau de Vilanova en la Valencia de principios del siglo XIV y las profecías escatológicas vinculadas a la llegada del Anticristo.

Interação genótipo-ambiente na densidade de gemas e comprimento de ramos de pessegueiro

The instability of environment between years in climates of subtropical regions difficult to obtain peach trees genotypes with wide adaptation and stable production, contributing to poor crop. The climate instability can affect development stages as flower bud and vegetative bud formation. The factors understanding that control the bud formation, presents elementary importance for effective solutions search to these problems. The objective this work is verify the temperature effect, relative humidity and rainfall on bud density and length shoot (Brindilas) and identify genotypes with more adaptability and stability for this character. Was used 12 peach trees genotypes growing in experimental orchard in the Technology Federal of Paraná State University, Campus Pato Branco with Cfa Köppen climate according to the classification. Data of rainfall, hourly temperature were collected by the weather station of Simepar. They were used three plants for genotype (rehearsal), identify five shoots per tree, in May of each year. Were carried analyzes of length shoot CR (cm), count number of flower bud (GF) and vegetative bud (GV). Also calculated the relationship between GF/GV and flower bud density and vegetative bud density. Evaluations were performer annual 2007-2014. With these data adaptability and stability analyzes were performed using Biplot methodology and correlations analyzes (Pearson) with climates variables. They used the weather data to calculate the sums of hours with temperatures below 20 °C, temperatures between 20-25 °C, temperature between 25-30 °C and temperature above 30 °C, considering the period of August 1fst of the previous period to February 28 of the following year. Pearson correlation coefficients were used for path analysis, GF and DGF as basic variables. For CR, GV and GF the highest average occurred in 2009/10 period. The genotypes ‘BRS Kampai’ and ‘BRS Libra’ highest CR. They are considered stable and adapted as the CR genotypes ‘Casc. 967’ and ‘BRS Kampai’. There was negative correlation between CR and GV for Σh <20 ° C, Σh> 30 °C and Σh with URA <50% and positive correlation between these variables and Σh 25-30 °C and Σh with URA> 70%. The evaluation of GV ‘Cons. 681’ and ‘Casc. 1055’ can be considered adapted and stable. The lowest average was presented by the genotype ‘Sta. Áurea’ though the genotype is also stable. In GF evaluation genotypes are considered adapted ‘BRS Bonão’, ‘Casc. 1055’, ‘Cons. 681’ with adaptability to all evaluated period. In path analysis was direct effect Σh 25-30 °C on flower bud density. In evaluating DGV and DGF and the variations are due to genetic effect. The most adapted and stable genotypes for DGV were ‘T. Beauty’, ‘T. Snow’, ‘Casc. 1055’ and ‘Cons. 681’. CR and GV variables are strongly affected by environment. GF is strongly affected by genetic conditions and moderately affected by environment. DGV and DGF are affected basically by genetic conditions.

Ohjaus ja oppilaiden urapohdinta. Turkulaisten peruskoulun päättöluokkalaisten ohjauskokemukset urapohdinnan selittäjinä

Tutkimuksessa selvitetään turkulaisten peruskoulun päättöluokkalaisten urapohdintaeroja ja sitä, miten oppilaiden arviot opettajien ja oppilaanohjaajien toteuttamasta ohjauksesta ovat yhteydessä heidän urapohdintaansa. Tutkimuksen kohdejoukkona ovat ensi sijassa yleisopetusta antavien suomenkielisten peruskoulujen yhdeksäsluokkalaiset. Tutkimus on poikkileikkaustutkimus, jossa tarkastellaan oppilaiden kokemuksia ohjauksen saatavuudesta ja hyödyllisyydestä sekä urapohdinnasta peruskoulun päättyessä. Tutkimusaineisto koottiin yhteishaun jälkeen huhti–toukokuussa 2014. Vuoden 2004 perusopetuksen opetussuunnitelman perusteista johdettujen väittämien avulla selitetään urapohdinta-mittarin sisältämien muuttujien vaihtelua. Taustamuuttujina käytetään oppilaiden koti- ja koulutaustaa. Urapohdinta-mittari on johdettu CIP-teoriasta (Cognitive Information Processing) ja muokattu CTI-mittarista (Career Thoughts Inventory). Tutkimusaineisto (N = 887) on koottu Webropol-kyselyn avulla. Oppilaiden urapohdintaa mitattiin neljän summamuuttujien avulla. Mittariston 48 väittämästä muodostettiin urapohdinta-summamuuttuja. Tämän lisäksi urapohdinnan osa-alueita arvioitiin sitoutuminen-, epävarmuus- ja konflikti-summamuuttujan avulla. Sitoutuminen-summamuuttuja mittasi sitä, miten vaikeaksi oppilas koki yhteen ura- ja jatkokoulutusvalintaan sitoutumisen. Epävarmuus-summamuuttuja mittasi päätöksenteon epävarmuutta ja konflikti-summamuuttuja vaikeutta tasapainoilla omien ajatusten ja toisaalta merkittäviksi koettujen läheisten ajatusten välillä. Kaikkien opettajien ohjaustyön näkökulmasta parhaiten hyvää urapohdintatulosta, jatkokoulutukseen sitoutumista ja päätöksentekovarmuutta ennustivat oppilaan hyvät kokemukset yhteistoiminnasta, hänen myönteinen suhtautumisensa koulunkäyntiin ja opintosuoritukset. Myös itseohjautuvuus oli tilastollisesti merkitsevässä yhteydessä urapohdintaan. Itseohjautuvuus-summamuuttuja mittasi sitä, oliko oppilas kokenut, että ohjaukselle asetetut tavoitteet saavutettiin. Opettajien tulisi kiinnittää ohjauksessaan huomiota hiljaisiin ja vähän huomiota vaativiin oppilaisiin ja tukea kaikkien oppilaiden toimintakykyä. Opinto-ohjaajan taas tulisi panostaa oppilaan itsetuntemuksen kehittämiseen ja valmiuteen toimia suunnitelmallisesti. Toisen asteen nivelvaiheohjauksen painopiste tulisi siirtää päättöluokkaa varhaisemmaksi. Tutkimustulos ei tue ajatusta, että tehostettu oppilaanohjaus kohdennettaisiin opintomenestyksen mukaan, koska heikkoja urapohtijoita oli kaikissa keskiarvosanaluokissa. Opinto-ohjaajien tulisi panostaa tieto- ja viestintätekniikan hyödyntämiseen ja tehostaa koko koulun työelämäyhteistyötä.
