This is the first study to provide comprehensive analyses of the relative performance of both socially responsible investment (SRI) and Islamic mutual funds. The analysis proceeds in two stages. In the first, the performance of the two categories of funds is measured using partial frontier methods. In the second stage, we use quantile regression techniques.By combining two variants of the Free Disposal Hull (FDH) methods (order-m and order-?) in the first stage of analysis and quantile regression in the second stage, we provide detailed analyses of the impact of different covariates across methods and across different quantiles. In spite of the differences in the screening criteria and portfolio management of both types of funds, variation in the performance is only found for some of the quantiles of the conditional distribution of mutual fund performance. We established that for the most inefficient funds the superior performance of SRI funds is significant. In contrast, for the best mutual funds this evidence vanished and even Islamic funds perform better than SRI.These results show the benefits of performing the analysis using quantile regression.

In the first, the performance of the two categories of funds is measured using partial frontier methods. In the second stage, we use quantile regression techniques. By combining two variants of the Free Disposal Hull (FDH) methods (order- m and order- α) in the first stage of analysis and quantile regression in the second stage, we provide detailed analyses of the impact of different covariates across methods and across different quantiles. In spite of the differences in the screening criteria and portfolio management of both types of funds, variation in the performance is only found for some of the quantiles of the conditional distribution of mutual fund performance.

We analyse the performance persistence of Islamic and Socially Responsible Investment (SRI) mutual funds. We adopt a multi-stage strategy in which, in the first stage, partial frontiers’ approaches are considered to measure the performance of the different funds in the sample. In the second stage, the results yielded by the partial frontiers are plugged into different investment strategies based on a recursive estimation methodology whose persistence performance is evaluated in the third stage of the analysis. Results indicate that, for both types of funds, performance persistence actually exists, but only for the worst and, most notably, best funds. This result is robust not only across methods (and different choices of tuning parameters within each method) but also across both SRI and Islamic funds—although in the case of the latter persistence was stronger for the best funds. The persistence of SRI and Islamic funds represents an important result for investors and the market, since it provides information on both which funds to invest in and which funds to avoid. Last but not least, the use of the aforementioned techniques in the context of mutual funds could also be of interest for the non-conclusive literature.

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.

Mineral and chemical composition of alluvial Upper-Pleistocene deposits from the Alto Guadalquivir Basin (SE Spain) were studied as a tool to identify sedimentary and geomorphological processes controlling its formation. Sediments located upstream, in the north-eastern sector of the basin, are rich in dolomite, illite, MgO and KB2BO. Downstream, sediments at the sequence base are enriched in calcite, smectite and CaO, whereas the upper sediments have similar features to those from upstream. Elevated rare-earth elements (REE) values can be related to low carbonate content in the sediments and the increase of silicate material produced and concentrated during soil formation processes in the neighbouring source areas. Two mineralogical and geochemical signatures related to different sediment source areas were identified. Basal levels were deposited during a predominantly erosive initial stage, and are mainly composed of calcite and smectite materials enriched in REE coming from Neogene marls and limestones. Then the deposition of the upper levels of the alluvial sequences, made of dolomite and illitic materials depleted in REE coming from the surrounding Sierra de Cazorla area took place during a less erosive later stage of the fluvial system. Such modification was responsible of the change in the mineralogical and geochemical composition of the alluvial sediments.

Since its excavation in the summer of 1973, El Niño cave has been considered a key site to understand the process of production economy and pottery technology introduction in South-eastern Iberian Peninsula, and especially to approach how such process could have affected people already settled in the Segura mountains. However, data from El Niño cave was very fragmentary, due to the lack of a broad study of Neolithic occupations of the site. In this paper, we present the analysis of pottery, lithic industry and faunal remains, as well as the existing dates from the site´s Holocene levels. The review of different evidence from the site allows suggesting that El Niño cave would have probably acted as a hunting and shepherding station, being a logistical site of larger places. However, limitations due to the fact that we are dealing with a 40- year-old excavation, prevent specifying how the process of Neolithic introduction in the Segura Mountains occurred.
