Conferencia sobre el ALCA, el TLC CA- EE.UU

Introducción ¿Por qué Centroamérica pone tanto empeño en la prosecución de un acuerdo que implica concesiones sustanciales a EE.UU. y que, además, exige a los países centroamericanos un elevado esfuerzo de adecuación y de reducciones arancelarias? Ante el nuevo TLC de Centroamérica con los EE.UU. se pueden anticipar negociaciones en agricultura, integración de servicios y en el contenido de las leyes salariales y de regulación ambiental, Asimismo, la apertura del mercado de seguros, las telecomunicaciones, aeropuertos, etc. En la agenda de EE.UU. no se excluye nada. Todos los bienes y servicios estarán incluidos, desde productos agrícolas fuertemente subsidiados en EE.UU., hasta el agua potable seguridad social, educación universitaria y ciertos servicios bancarios

Silicon Photonic Device for Wavelength Sensing and Monitoring

Over the last decade advances and innovations from Silicon Photonics technology were observed in the telecommunications and computing industries. This technology which employs Silicon as an optical medium, relies on current CMOS micro-electronics fabrication processes to enable medium scale integration of many nano-photonic devices to produce photonic integrated circuitry. However, other fields of research such as optical sensor processing can benefit from silicon photonics technology, specially in sensors where the physical measurement is wavelength encoded. In this research work, we present a design and application of a thermally tuned silicon photonic device as an optical sensor interrogator. The main device is a micro-ring resonator filter of 10 $\mu m$ of diameter. A photonic design toolkit was developed based on open source software from the research community. With those tools it was possible to estimate the resonance and spectral characteristics of the filter. From the obtained design parameters, a 7.8 x 3.8 mm optical chip was fabricated using standard micro-photonics techniques. In order to tune a ring resonance, Nichrome micro-heaters were fabricated on top of the device. Some fabricated devices were systematically characterized and their tuning response were determined. From measurements, a ring resonator with a free-spectral-range of 18.4 nm and with a bandwidth of 0.14 nm was obtained. Using just 5 mA it was possible to tune the device resonance up to 3 nm. In order to apply our device as a sensor interrogator in this research, a model of wavelength estimation using time interval between peaks measurement technique was developed and simulations were carried out to assess its performance. To test the technique, an experiment using a Fiber Bragg grating optical sensor was set, and estimations of the wavelength shift of this sensor due to axial strains yield an error within 22 pm compared to measurements from spectrum analyzer. Results from this study implies that signals from FBG sensors can be processed with good accuracy using a micro-ring device with the advantage of ts compact size, scalability and versatility. Additionally, the system also has additional applications such as processing optical wavelength shifts from integrated photonic sensors and to be able to track resonances from laser sources.

Synthetic portfolio for event studies: Estimating the effects of volatility call auctions

We propose a method denoted as synthetic portfolio for event studies in market microstructure that is particularly interesting to use with high frequency data and thinly traded markets. The method is based on Synthetic Control Method and provides a robust data driven method to build a counterfactual for evaluating the effects of the volatility call auctions. We find that SMC could be used if the loss function is defined as the difference between the returns of the asset and the returns of a synthetic portfolio. We apply SCM to test the performance of the volatility call auction as a circuit breaker in the context of an event study. We find that for Colombian Stock Market securities, the asynchronicity of intraday data reduces the analysis to a selected group of stocks, however it is possible to build a tracking portfolio. The realized volatility increases after the auction, indicating that the mechanism is not enhancing the price discovery process.

This paper illustrates the impact of the Universidad Estatal a Distancia  (UNED, by its Spanish acronym) in supporting and professionalizing the vulnerable groups of the Costa Rican society, including prison inmates, persons with physical disability, individuals from remote areas, among others.  This study attempts to answer this type of questions: What kind of support has been provided to these sectors?  What are the challenges faced by distance education universities to succeed?  How does UNED have solved these challenges?  What is the impact of the Universidad Estatal a Distancia on the Costa Rican society for the professionalization of its population?  Documentation and statistics have been used in the study; in addition, two people who graduated from UNED were selected to illustrate the type of cases the University serves.(1) Translator’s note: It refers to the “Costa Rican Distance Education State University”.

A era Vargas e um Estado de bem-estar conservador

O objetivo do presente estudo foi desenvolver uma discussão teórica acerca do projeto varguista que pôde ser percebido como uma tentativa de criação de um "Estado de bem-estar" no Brasil. Uma ampla base teórica traz elementos de análise sobre Estado de bem-estar, como contribuições sobre o processo de engajamento do Estado na constituição de estratégias para lidar com a "questão social", os motores desse engajamento, os atores envolvidos e o peso de seus papéis, os objetivos dos projetos de Estado de bem-estar e as consequências na instituição dos welfare states. A partir da proposta de Esping-Andersen de compreensão de diferentes regimes de welfare state - conservador, liberal e social-democrata - análise do projeto varguista resultou como enquadrado no modelo conservador. A saída corporativa, com a construção de políticas sociais - marcadamente trabalhistas -, apresentou-se como novo marco de coesão social, pelo qual poderia ser permitida a participação da classe trabalhadora. Assim como no modelo conservador sistematizado por Esping-Andersen, os direitos sociais brasileiros tiveram um reduzido potencial desmercantilizador se verificados na relação com a ideia de "cidadania regulada", pois indica uma cidadania orientada apenas para grupos ocupantes de categorias profissionais reconhecidas legalmente e pela qual a relação salarial foi traduzida em direitos e garantida constitucionalmente. As políticas sociais apresentam-se como verdadeiras políticas de formação de classe: a cidadania regulada transformava-se em promessa de inclusão, moldando as perspectivas e aspiração da classe trabalhadora e assim, legitimando a luta pela sua própria efetivação.

"Falta alguém em Nuremberg?: a repressão do primeiro governo Vargas revelada pela imprensa e legislativo nos anos 1940"

O trabalho busca analisar o papel de dois setores representativos brasileiros (imprensa e poder legislativo), de 1945 a 1948, na investigação e divulgação de práticas repressivas do Estado brasileiro de 1935 a 1945 descambando para o tema da tortura no período. Para tal, tem-se como objeto empírico parte das publicações do conglomerado editorial Diários Associados e a formação da Comissão Parlamentar de Inquérito dos Atos Delituosos da Ditadura. Tomados no bojo da redemocratização a partir de 1945, as reportagens e a Comissão possuíram uma profunda interrelação nas denúncias às torturas ocorridas antes mesmo da instauração do Estado Novo. Ao se estudar o tema, observa-se que essas acusações, embora comuns, não encontraram eco e se perderam tanto na possibilidade de ações judiciais (no caso da Comissão Parlamentar) como à memória. O objetivo deste trabalho é, então, demarcar o caminho das denúncias e apontar as causas que culminaram no seu esquecimento público.

J.W. Spencer fonds, 1866, 1881-1921

Joseph William Winthrop Spencer (commonly known as J.W. Spencer) was a geologist and geomorphologist best known for his work on the geology of southern Ontario and the Great Lakes. He was born in Dundas, Upper Canada in 1851, but moved to Hamilton, Ontario in 1867. In 1871, he began studies in geology at McGill College in Montreal. In 1875 he worked in the Michigan copper mines and shortly afterwards prepared a thesis on the copper deposits. He submitted this thesis to the University of Gottingen in Germany in 1877 and was awarded a doctorate in geology, the second Canadian to earn a doctorate in this field. In 1880, he became a professor of geology and chemistry at King’s College in Windsor, N.S. Subsequently, he taught at the University of Missouri, and then the University of Georgia, but moved to Washington, D.C. in 1894, where he worked as a consultant geologist. Spencer spent much of his life studying preglacial river valleys in Ontario and the origins of the Great Lakes, as well as the Niagara River and Falls. In 1907, he published a book titled The Falls of Niagara: their evolution and varying relations to the Great Lakes. His opinions in these areas differed from some of his contemporaries, namely the American geologist Grove Karl Gilbert. Gilbert published a review of the The Falls of Niagara that exposed some flaws and inaccuracies in Spencer’s estimate of the age of the falls. Spencer’s studies also took him to the Caribbean and Central America. In 1920 he moved back to Canada, but died the following year.

Revisión y análisis de la estructura de costos del transporte terrestre de crudo en Colombia - Pacific Rubiales Energy 2012

Se espera que la producción de petróleo en Colombia supere para 2015 el millón de barriles por día. Sin embargo, a 2012, tres años antes de lo esperado, nos acercamos a la meta produciendo cerca de 900kbpd. Este progresivo crecimiento indica que es urgente fortalecer la infraestructura de transporte para crudo en el país, apoyándose en alternativas secundarias como el transporte de crudo por carrotanque para alivianar el sistema, siendo esta modalidad una “válvula de escape” para las petroleras. Consientes de los retos que esto implica, es necesario encontrar una estructura de costos óptima que permita fijar fletes razonables y competitivos en el mercado de transporte de crudo, sabiendo que un flete de estas características f ideliza y alinea a los proveedores (en este caso las empresas transportadoras prestadoras del servicio), a buscar el mismo objetivo: crecimiento. De esta forma Pacific Rubiales, la segunda petrolera con mayor presencia en el país podrá abrazar su operación, estableciendo no solo una sólida estrategia de evacuación del crudo por los oleoductos, sino a su vez un sistema efectivo de transporte por tierra, donde todos los involucrados en la cadena de valor se encuentren altamente fidelizados y satisfechos con las condiciones de operación que brinde la empresa; Traduciéndolo en pocas palabras, a un esquema con una operación segura, confiable, rentable y donde todos ganan. Es importante resaltar que la estructura actual para la definición de fletes, planteada por el gobierno a través del Software Sice, no se ajusta a la operación de petroleras como Pacific Rubiales, debido a las mismas características de la operación (ubicación de campos) y, a variables fijas en el sistema de información como: el real consumo y rendimiento del combustible en las rutas establecidas y, los costos de mantenimiento.

Efectos reglamentarios y jurisdiccionales del derecho comunitario Andino sobre el derecho administrativo colombiano

Este trabajo se soporta sobre una base conformada por dos conceptos, que constituyen el horizonte contextual de la investigación: Derecho Administrativo y Comunidad de integración. Es claro que al hablar de una Comunidad de integración específica como la Comunidad Andina (CAN), incide de forma directa en la actividad del derecho administrativo.Ha sido necesario que los países que conforman los grupos de integración económica cedan parte de sus competencias para crear un ordenamiento jurídico de orden supranacional, el cual modifica la dinámica social de las relaciones comerciales y afecta la estructura de la administración pública, haciendo que el derecho administrativo no se limite a interactuar solo con derecho nacional. Esta mutua dependencia de las políticas internas y las regionales se realiza, entonces, cada vez que existe participación y compromiso de los Estados frente a las decisiones, de carácter vinculante o no. En esa medida surge el problema de investigación tendiente a esclarecer cómo ha sido la adopción de las decisiones e interpretaciones, emanadas de los mecanismos oficiales del Derecho Comunitario Andino, en el ordenamiento jurídico colombiano. La existencia de varios puntos de vista con respecto a la obligatoriedad o no de dicha adopción, moldea un tema de suficiente amplitud y profundidad para ser estudiado en un trabajo de investigación.
