Tesis para optar al grado de Magíster en Ciencias, Mención Astronomía / Buscamos estrellas tipo RR Lyrae en zonas distantes del halo de la Vía Láctea utilizando datos ya existentes: UltraVISTA, una campaña con observaciones en el infrarojo cercano diseñada para obtener imágenes profundas del campo COSMOS, y SUDSS, una extensión del Dark Energy Survey (DES) que añade observaciones en los extremos del tiempo de obser- vación de DES en varios filtros, con la finalidad de observar las curvas de luz de supernovas a alto redshift. Los resultados de la búsqueda de RR Lyrae con estos datos fueron nulos. Ante estos resultados realizamos observaciones simuladas de RR Lyrae, bajo las mismas condi- ciones de los datos observados, demostrando que la cadencia utilizada en las observaciones no permite la identificación del período de las estrellas RR Lyrae. Finalmente probamos el método desarrollado con datos de HiTS (High Cadence Tran- sient Survey), una campaña dedicada a detectar transientes en el óptico, principalmente las primeras horas de las explosiones de supernovas. Luego de responder favorablemente a las observaciones simuladas, logramos identificar en los datos de HiTS 2015A un total de 106 RR Lyrae 7 de las cuales se encuentran a una distancia mayor a 100 kpc.

Ethnicity is one of the powerful concepts in social sciences. It encourages social scientists coming from different academic disciplines to think over its roles, influences and power within communities which are shaped at various level. Particularly in the globalised world, traditional approaches such as primordalism, essentialism or instrumentalism have difficulty to provide a powerful framework to understand complexity and power of ethnicity in diasporic spaces which host different identity formations, experiences and cultural hybridisation. Accordingly, these traditional approaches miss differences among human beings who associated themselves with certain ethnicities. For this reason, social scientists tend to understand the concept of ethnicity with alternative approaches. Unlike traditional approaches, social constructionism does not seen ethnicity as fixed, stable homogeneous things. Rather, ethnicities refer to a cognitive process which is shaped by people’s attitudes, perceptions or interactions. Approaching to ethnicity as a cognitive process allows us to go beyond universality and sharp definitions of ethnicity. Also, it emerges out various interpretations in diasporic spaces where ethnicity can be reproduced in various ways. By relying on this theoretical framework, this research seeks to understand the reproduction of Armenianness in diasporic spaces. Through focusing on Turkish, Lebanese and British Armenians, it searches answers for following questions a) What are the components of Armenianness in Turkey, Lebanon and Britain? b) How are the components of Armenianness interpreted in diasporic communities in Turkey, Lebanon and Britain? c) How is Armenianness reproduced among Armenian youngsters in Turkey, Lebanon and Britain? It is hypothesised that Armenianness is not a holistic form, it can be observed as “a patchwork” consisting of various patterns and colours. In order to materialise research aims and goals, the research was supported by field works in Istanbul, Beirut and London between 2011 and 2013. Throughout the data collection period, in-depth interviews, ethnography and participant observation were preferred to not only identify components of Armenianness, but also to create datasets for comparing and analysing the cases. The datasets have been analysed by ANCO-HITS to demonstrate similarities and differences among various reproduction forms of Armenianness in numerical ways. As a result of the ANCO-HITS analysis, Armenianness was ranked in each case according to participants’ scores. Later on, two participants (having the most negative and positive) were introduced through referring findings and fieldwork notes which derived from ethnography. This research shows that Armenianness is observed in various forms. It is highly heterogeneous in diasporic spaces and experienced in different ways. Interpretations of youngsters are varied. It sometimes seems to be ethnic, nationalist, political, moderate or congregational. It also demonstrates that attitudes, perceptions as well as interactions of youngsters with Armenians and non-Armenians can be effective parameters differentiate Armenianness in diasporic spaces.

When the Sun Hits is a feature length film concerned with the delicate relationship between the individual and the whole. A young man named John has fallen into a state of social paralysis since his father's death. He no longer knows how to relate to others and the world around him. Rather than looking to friends and family for support he closes himself off. After the mysterious disappearance of his mother, John blames himself for her leaving. He tries his best to reconnect with his old life, but finds himself making the same mistakes over and over. When his friend Tracy reaches out to him, he bitterly rejects her and once again finds himself alone. It is then that John puts his old life behind him and sets off to make amends with his mother. John has no idea where his mother might be or if she will accept him. Nonetheless, he reaches into the abyss to see if someone is there, waiting for him. The structure of the film is nonlinear as it deviates from traditional narrative form. The intent of this thesis is to serve as a post-film reflection that discusses the relation between my views on cinema and the film I made. The paper will shift between the general themes of the narrative and the film theory working behind it all. It will explore the idea of cinema as an extension of the mind and how this is present in the film. By using specific examples from the film this theory of cinema can be fleshed out and an insight into my process may be gleaned.

[pt] O ambiente baseado em hyperlink possui na sua topologia informações substanciais sobre o seu conteúdo. Baseado nesse tipo de ambiente, Jon Kleingerg desenvolveu um conjunto de algoritmos, popularmente conhecido como HITS (Hyperlink Induced Topic Search), que utiliza a estrutura de hyperlinks na WWW para extrair essas informações. O foco central desses algoritmos é a classificação de tópicos de busca de caráter geral na WWW, através da descoberta de páginas que representam autoridade sobre tais tópicos. Para tanto, os algoritmos formulam a noção de autoridade considerando o relacionamento, decorrente da estrutura de hyperlink, entre o conjunto de páginas que são autoridades relevantes e o conjunto de páginas que apontam para essas, denominadas de hubs. Jon Kleingerg definiu, portanto, uma relação de interdependência entre os conjuntos anteriormente citados: uma boa autoridade será uma página apontada por bons hubs e um bom hub será uma página que aponta para boas autoridades. Neste trabalho, propomos a extensão do modelo formulado por Jon Kleingerg, através da inserção de novos conceitos nas relações de interdependência entre autoridades e hubs. Assim, formulamos um algoritmo estendido, XHITS (Extended Hyperlink Induced Topic Search), que visa melhorar a classificação das autoridades do ambiente. Nessa extensão as autoridades são apontadas por bons hubs, às vezes apontadas por bons portais e também apontam para boas novidades. Os bons hubs são páginas que apontam para boas autoridades e novidades, e são apontados por bons portais. As boas novidades são páginas que são apontadas pelas boas autoridades, pelos bons hubs e pelos bons portais e bons portais são páginas que apontam para as boas autoridades, para bons hubs e para boas novidades. Adicionalmente, mostramos que o algoritmo proposto converge e também os diversos resultados experimentais que indicam a melhoria na precisão dos hiperdocumentos recuperados. / [en] The network structure of a hyperlinked environment can be a rich source of information about the content of this environment. Jon Kleinberg developed a set of algorithms, called HITS (Hyperlink Induced Topic Search), for extracting information from the hyperlink structures of those environments. The aim of these algorithms is the distillation of broad search topics, through the discovery of related authoritative information sources. The notion of authority is based on the hyperlink structure relationship between a set of relevant authoritative pages and the set of hubs. Thus, hubs and authorities exhibit what could be called a mutually reinforcing relationship: a good hub is a page that points to many good authorities; a good authority is a page that is pointed by many good hubs. In this work, we present the XHITS (Extended Hyperlink Induced Topic Search) algorithm, an extension of the HITS algorithm by introducing new concepts on the mutually reinforcing relationship. In XHITS, a good authority is a page that is pointed by many good hubs, some good portals and points to good novels; a good hub is a page that points to many good authorities, some good novels and is pointed by some good portals; and a good novel is a page that is pointed by good authorities, some good hubs and some good portals; a good portal is a page that points to some good authorities, some good hubs and some good novels. In addition, we show that XHITS converges and, through some experiments, the improved quality of the hyper documents retrieved.

Intimate partner violence (IPV) during pregnancy can lead to a myriad of poor physical and psychological outcomes for both mother and child. There is a paucity of research examining IPV risk factors for rural pregnant women and on information regarding the course of the specific types of IPV throughout pregnancy. The current project was an investigation of the prevalence of IPV and IPV risk factors for different types of IPV in an Appalachian pregnant sample that contained women from both rural and nonrural locations (Study 1), and was an examination of the occurrence of any IPV and the different types of IPV throughout the course of pregnancy (Study 2). Study 1 included 1,063 pregnant women participating in the Tennessee Intervention for Pregnant Smokers (TIPS) research project. IPV prevalence rates during pregnancy, measured using a modified HITS IPV screen, were approximately 26% for psychological violence, 2% for physical violence, and 1% for sexual violence. Chi-squared analysis indicated that rural pregnant women were not significantly more likely to experience any of the types of IPV compared to nonrural pregnant women. Additionally, logistic regression analysis supported previous literature findings that pregnant women who are unmarried, younger, have an unplanned pregnancy, have high levels of stress, and have low levels of social support are at a greater risk of experiencing any type of IPV during pregnancy compared to pregnant women not possessing those risk factors. However, rural status was not a significant predictor or modifier of IPV. Study 2 participants included a subsample of 337 pregnant women who indicated they had experienced IPV at any time during the course of their pregnancy. Generalized estimating equation logistic models indicated that women who experienced IPV at some point during pregnancy were more likely to experience IPV during the third trimester. Both studies support the importance of screening for specific types of IPV throughout pregnancy. Information obtained from the current research is valuable to health care providers because it is important they are aware of IPV risk factors and that different types of IPV, especially psychological IPV, can occur at any time during pregnancy.
