Intervención educativa en conductas de riesgo en salud sexual y reproductiva en la población universitaria de Salamanca

[ES]La sexualidad se considera un fenómeno multidimensional, que afecta a aspectos sociales, psicológicos, biológicos, culturales, y cuya consecuencia no afecta única y exclusivamente al coito, sino a una serie de pensamientos, sentimientos y sensibilidades, que interfieren en la relación del día a día. Por ello podemos considerar a la sexualidad, como una expresión psicológica y social de los individuos en el seno de una cultura y un momento determinado (Reina et al

K+ Signatures in the ProtoDUNE-SP detector at CERN

Los neutrinos son la segunda partícula más abundante del universo, y aún así la menos entendida. El descubrimiento de sus oscilaciones de sabor ha demostrado que son partículas masivas, en contradicción con la descripción del Modelo Estándar de Física de Partículas. Durante los últimos veinte años más de una decena de experimentos han intentado caracterizar el fenómeno de las oscilaciones usando neutrinos generados en reactores nucleares, en la atmósfera, en el sol y en aceleradores de partículas, pero el conocimiento de algunos de los parámetros que las describen es todavía limitado. Este es el caso de la fase compleja de violación de la simetría CP, un parámetro que podría estar íntimamente relacionado con el origen del universo. Por este motivo se ha propuesto el experimento DUNE, un nuevo experimento enfocado al estudio de los neutrinos que se está construyendo actualmente en Estados Unidos. Dicho experimento contará con el haz de neutrinos más intenso jamás generado, que será caracterizado en dos detectores distintos para obtener información sobre los parámetros de las oscilaciones. Particularmente, el detector lejano estará localizado en SURF, a 1.5 kilómetros bajo tierra, y estará formado por cuatro cámaras de proyección temporal de argón líquido con sistemas de fotodetección complementarios basados en la tecnología X-ARAPUCA. Este tipo de detector ofrece un amplio abanico de potenciales estudios físicos a parte de las oscilaciones de neutrinos, como es el caso de la búsqueda de la desintegración del protón. Antes de la instalación de DUNE, se ha desarrollado el programa ProtoDUNE en el CERN, en el cual la tencología LArTPC se está estudiando usando los detectores de este tipo más grandes construidos hasta la fecha. En este trabajo hemos explorado las capacidades de ProtoDUNE-SP para identificar kaones de baja energía mediante el uso de su información calorimétrica, lo cual es una de las claves para la viabilidad de la búsqueda de la desintegración del protón en DUNE. Se ha obtenido una población de 1200 kaones con una pureza del 50%, demostrando dichas capacidades, y permitiendo un estudio detallado de su pérdida de energía por unidad de longitud. Se ha podido observar en dicho estudio que la simulación subestima la pérdida de energía para kaones de bajo momento. Este resultado puede usarse ahora para corregir las simulaciones y para mejorar los estudios de sensbilidad de DUNE para la búsqueda de la desintegración del protón. Adicionalmente, en este trabajo también se presentan los resultados de la selección del modelo de fotomultiplicador a usar en el sistema de fotodetección de DUNE. Dos fabricantes distintos, HPK y FBK, fabricaron modelos específicos acorde a los requisitos físicos de DUNE, que han sido testeados en condiciones de criogenia. Se ha observado una preferencia hacia los modelos con un mayor tamaño del celda y una mayor resistencia de extinción, así como un mejor funcionamiento de los modelos de HPK frente a los de FBKNeutrinos are the second most abundant particle in the Universe, yet the less understood. The discovery of their flavor oscillations have demonstrated that neutrinos are massive, constituting the first proof of physics beyond the Standard Model. During the last twenty years, tens of experiments have worked to measure the different parameters describing the oscillation phenomena using solar, atmospheric, reactor and accelerator neutrinos. However, some of these parameters have not been measured precisely enough, among which the CP violation phase stands. This phase quantifies how differently neutrinos and antineutrinos oscillate, and a value different from zero could be one of the ingredients to explain the existence of the Universe itself. For this reason, the DUNE experiment has been proposed to keep studying neutrinos beyond. It will be a long-baseline neutrino experiment located at the US, and it will consist in the most neutrino beam ever produced, and two detectors to characterize the oscillated and the unoscillated neutrino flux. The Far Detector, located 1.5 km underground in SURF, will be using the emerging and outstanding Liquid Argon Time Projection Chamber detector technology at a scale never used before, combined with the novel X-ARAPUCA technology for photon detection. The excellent physics possibilities of DUNE allows it to expand its physics programme to also include proton decay searches, multi-messenger astronomy and a wide range of BSM physics. Before the starting of the installation of DUNE, the ProtoDUNE program has been developed at CERN to validate the LArTPC technology. The largest prototypes of DUNE have been built and exposed to a charged particle beam to study the performance of this kind of experiments. In this work, we explore the capabilities of the ProtoDUNE-SP detector to identify low energy kaons by means of their calorimetric information, which is fundamental for the viability of proton decay searches in DUNE's FD. A sample of 1200 secondary stopping kaons has been obtained with a purity of 50%, demonstrating the LArTPC capabilities to perform proton decay searches, and allowing to perform a thoughtful analysis of the kaons' dE/dx. It has been found than apparently the MC simulation is underestimating the energy loss at very low energies. This result, after further confirmation, will be used to correct the simulation and to improve the proton decay sensitivity studies. In addition to this, this work presents the result of the SiPM down-selection procedure developed by DUNE, in which the SiPM model to be used in the Photon Detection System. Sensors of two different vendors, HPK and FBK, were tested in cryogenic conditions, finding that larger pitch model with higher quenching resistances were preferred due to a reduction on the correlated noise probability. It was also found that, in general terms, HPK's SiPMs performed better than FBK's

Documental y narrativa transmedia. Estrategias creativas y modelos de producción

Esta investigación, planteada como un recorrido a través de lo inmediato en el campo de las nuevas narrativas audiovisuales, tiene como objeto el acercamiento, desde una actitud analítica, al universo relacional existente entre el documental y la narrativa transmedia en el contexto de la convergencia mediática; y desde ahí, abundar en la emergencia y prácticas de la actual producción transmedia documental y sus distintas estrategias creativas y modelos de producción empleados. A su vez, este trabajo, estudia los principales cambios operados en el seno del documental contemporáneo a partir del surgimiento y cristalización de nuevas formas y estrategias documentales, así como de las distintas retóricas que se insertan en el escenario mediático digital, siempre en constante mutación, resultado de la hibridación entre tecnología y creación. Es así como dentro de este territorio mestizo del denominado “cine de lo real” contemporáneo, nos encontramos con etiquetas de nuevas tendencias y formatos (que van desde el mockumentary al documental expandido, entre otros, hasta llegar al documental interactivo como último género consolidado) y con toda una batería de procedimientos formales y estrategias retóricas que articulan una onda expansiva de asombrosa libertad creativa para conformar nuevas estéticas, capaces de reconfigurar dispositivos documentales de representación y enunciación tan diversos como sugerentes. En este marco, del cual se realiza una suerte de taxonomía de sus rasgos y formatos más significativos, emerge la narrativa transmedia vinculada a lo real, al documental, con su expansión del relato en distintos medios y plataformas. Tras el establecimiento de conceptualizaciones asociadas a la narrativa transmedia, se abunda en cómo opera ésta en el seno de la producción de ficción y en el propio de la producción documental, para establecer los principios que constituyen esta realidad, en permanente estado de construcción, por parte de los consumidores, así como en sus modos y procesos de producción.The object of this research, set out as a study of the current situation in the field of the new audiovisual narrative techniques, is to approach, from an analytical point of view, the relational universe that connects the documentary with the transmedia narrative in the context of media convergence, and thence study in greater depth the emergence and practice of contemporary transmedia documentary production and the different creative strategies and production models employed therein. This study also analyses the important changes that have taken place in the field of the contemporary documentary with the rise and increasing implementation of new documentary forms and strategies as well as the different strategies of rhetoric that have evolved in the realm of digital media, exposed to constant change due to the hybridization of technology and the act of creation. In this hybrid territory of what is now termed the contemporary “cinema of the real”, we thus find tags of new tendencies and formats (from the “mockumentary” to the expanded documentary, among others, leading to the latest genre to be consolidated up to now, the interactive documentary) with a wide range of formal procedures and rhetorical strategies that articulate a huge wave of astonishing creative freedom, all serving to constitute new aesthetics that manage to reshape the documentary devices of representation and narrative in a way that is both diverse and suggestive. In this context, whose most important features and formats will be the object of a detailed taxonomy, we will see the emergence of transmedia narrative linked to reality, to the documentary, with its storytelling strategy expanding into different medias and platforms. After establishing the conceptualizations associated with transmedia narrative, an analysis is undertaken of how it operates in the area of movie production as well as in the area of documentary production, in order to establish the principles that make up this reality in a permanent state of construction, both by the consumer and by the means and methods of production

Barbara Godard, a Translator's Portrait: Analysing the Reception of Québec's Roman au Féminin (1960-1990) in Anglophone Canada

The current dissertation is not only concerned with nourishing the Feminist Translation Studies field with an interdisciplinary perspective into Feminist Translator History. It strives for an understanding of Translation Studies, and Feminist Translation Studies in this particular case, as a cross-disciplinary space where the aims of various disciplines may converge (see Castro 2012). In the particular space of Feminist Translation/Translator History, and in line with Rundle's proposed synergies between Translation Studies and History (2014), the limitations of the so-called "discursive turn" in Feminist History" (Canning 1994) which, despite showing interest in how ideologies operate via historiographical discourse, is insufficiently familiar with the variety of Critical Discourse Analysis methodologies at our disposal (see Castro 2009). In this sense, the current thesis intends to be useful to feminist scholars across disciplines in their search for more fruitful, interdisciplinary methodologies duly integrating history, ideology, and discourse. The subject chosen for the current study is late feminist translator and scholar Barbara Godard (Toronto, 1942-2010), an agent actively participating in the Trudeau-Era's so-called "Canadianization", the establishment of a distinctively Canadian cultural ecosystem. In this particular context, higher-education institutions like York University, Godard's employer, had a leading role in the Canadian nation-making project, coincidental with the Centennial of the Confederation (1867-1967), and greatly contributed to spreading the notion of a thus-far non-existent, distinctive Canadian Literature among the population. The "Canadianization" project constitutes an interesting scenery to analyse Godard's feminist translator's agency in so far as it responds to the typical patriarchal pattern of synergetic relations between a literary polysystem and the underlying nation state's ideal concept of society. As a white settler society, Canada was far from acknowledging cultural and ethnic Otherness within its borders. What certainly worried the orchestrators of the Canadian nation-making project between the late 60s and 70s, be it politicians, scholars, or agents of the book industry in general, was therefore the growing conflict with Québec's own nation-making ideals and the resulting literary system, striving for independent cultural infrastructures. Taking the polysystem theory's analytical pattern as a point of departure, I intend to provide a sociocritical description of both the Canadian and the Québécois polysystem, in the means of better determining how Godard's feminist agency interacted with and grew out of them.The current dissertation is not only concerned with nourishing the Feminist Translation Studies field with an interdisciplinary perspective into Feminist Translator History.

DAPHNE Colaboración con el experimento DUNE

El Deep Underground Neutrino Experiment es un experimento de neutrinos que está actualmente en construcción en Estados Unidos de América y será su más grande y ambicioso experimento para las próximas décadas. En el experimento, mediante el uso de Argón líquido, los neutrinos que interactúen con ese gas noble generarán fotones a través de un proceso denominado centelleo. El sistema de detección de estas partículas de luz se llama el PDS, allí los fotones serán capturados por Fotomultiplicadores de Silicio (SiPMs), los cuales emitirán una señal eléctrica (Fotoelectrón) que será posteriormente procesada por un sistema electrónico. Las señales que surjan del PDS deben ser adquiridas y digitalizadas para poder realizar los estudios y análisis pertinentes. En esto ha venido contribuyendo la Universidad EIA con diferentes códigos firmware para operar la tarjeta DAPHNE (Electrónica del Detector Para Adquirir Fotones de Neutrinos) quien se encargará de este proceso. En el último año, nuestro grupo de trabajo se ha centrado en el desarrollo de algoritmos de salvaguardado y envío de datos automáticos de la tarjeta, denominados “Self-Trigger”, el cual ha sido exitosamente probado en el prototipo del experimento ProtoDUNE-II en el CERN. Hasta este momento las pruebas preliminares indican que dicho algoritmo posee una eficiencia de detección de alrededor del 55%, siendo la mejor alternativa probada hasta ahora

Stretching the Archives: Toward a Global Women’s Film Heritage

The book is the result of two years of networking, workshops, and conferences that aimed to bring together scholars, archivists, and filmmakers. The focus was on addressing gaps in our shared histories, with a particular emphasis on feminist cultural memory and film heritage in the Global South. This book combines feminist and anti-colonial research, and through the network, women and individuals identifying as female from around the world came together to share passions, frustrations, knowledge, and experiences related to film archives and restoration projects. These projects have often neglected the work of women from the Global South. Recognizing that the intersection of the anti-colonial movement with second wave feminism and the rise of film studies in the seventies provided a rich framework, the authors collectively decided to focus on that era to find a workable methodology for their diverse approaches to film history
