Market power gives certain market participants the ability to manipulate the market to their advantage when their product is not substitutable by competitors. Identification of generators which have the potential for market power either individually or within a small group is performed using sensitivity information from the linear programming optimal power flow (LP OPF). The impact of network constraints on admissible price perturbations are used to group generators that have the potential to exhibit local market power. Specific price perturbation vectors are found that highlight a constraint-induced locational advantage for these suppliers. In practice, this is most commonly observed in "load pockets," for which ISO policies mitigate market power.

The new educational context defined by the European Space for Higher Education (ESHE) encourages the student's autonomous work, that requires new tools for enhancing the information access. In this paper we present iCollege, an educational platform that is able to recover relevant information from international breaking news and present it classified; easing the burden of students ' and lecturers' work. Furthermore, it INTRODUCCIÓNNuestra experiencia docente nos permite manifestar que, siempre que sea posible, el uso de ejemplos reales para explicar los conceptos teóricos es una herramienta docente muy eficaz, ya que los estudiantes perciben la utilidad de los temas vistos en clase y les ayuda a entender su entorno social, cultural, económico y político. Internet y Las Tecnologías de Información y Comunicación (TIC) han permitido crear nuevos enfoques en la enseñanza. Sin embargo, dada la naturaleza dinámica y heterogénea de la Web, la sobrecarga de información es uno de los principales retos docentes.Dado que Internet es accesible en aproximadamente 150 países y brinda soporte a diferentes tecnologías, como indican en Sánchez y Taylor (2008), todo apunta a que hoy en día es la fuente más utilizada para documentarse por la sociedad y en particular por los estudiantes. En Lippincott (2005) se puede ver que el motor de búsqueda Google es el punto de partida para la mayoría de las consultas de un estudiante, hasta el punto de manifestar cierta dependencia de dicho motor. Algunos de los servicios de noticias más populares, como son los periódicos online, Google News o Yahoo News por ejemplo, presentan la información organizada por secciones y países. Sin embargo, éstas son demasiado generales y sin estructura, de forma que para AN INTERNATIONAL PLATFORM FOR TEACHING SUPPORT BASED ON BREAKING NEWS RESUMEN:En el nuevo contexto educativo definido por el Espacio Europeo de Educación Superior (EEES) se potencia el trabajo autónomo del estudiante, lo que requiere nuevas herramientas que faciliten el acceso a la información. En este trabajo presentamos iCollege, una plataforma educativa capaz de recopilar información de actualidad relevante de diferentes fuentes internacionales y presentarla clasificada por asignaturas y temas; aliviando así la carga de trabajo de docentes y alumnos. Además, permite fomentar el hábito de lectura en otras lenguas, facilita la integración de alumnos visitantes extranjeros y muestra los distintos puntos de vista que los medios de comunicación internacionales publican sobre un mismo asunto. Gracias a la integración con Campus Virtual o CMS se fomenta el trabajo colaborativo de los estudiantes y facilita la supervisión y evaluación por parte de los docentes.

The Web is now playing an important part in people's real-life activities. Scientists of not only computer science but also sociology and economics might be interested in mining on information directly related to real-life events, or news-related information on the Web. In this paper we propose a system to enable mining on news-related articles instead of raw web pages. There are functionally two tasks in our system: 1) mining for news-related articles and 2) duplicate elimination. For the first task, a novel approach for determining titles, contents and publication-times of news-related articles is presented. Anchor texts are firstly used to extract titles from HTML bodies and then contents are extracted right after titles. After that, crawl-times and are used to initially compute publication-times for all articles. At last, times extracted from HTML bodies, URLs and anchor texts are used to determine precise publication-times for possible articles. For the second task, a duplicate detection algorithm for news-related articles is described which is base on LCS (longest common subsequence) and achieves both high precision and high recall. The framework of this algorithm has been presented as a general-purpose algorithm for web pages in a previously published paper. In this paper we explain why this algorithm is particularly suitable for news-related articles and present corresponding implementation details. Evaluations have been conducted which show the effectiveness of our approaches.
