Metacognitive awareness and enhanced autonomy through the use of collaborative writing and "storybird"

116 páginas incluye diagramasEsta investigación demuestra como el uso de la escritura colaborativa a través de Storybird, una herramienta web que promueve la creación de historias, ayuda a los estudiantes mejorar su habilidad para escribir. Este estudio se realizó con dos grupos de estudiantes de nivel intermedio alto en el Instituto de Lenguas de la Universidad Distrital (ILUD) a lo largo de dos ciclos. Los resultados revelaron que la escritura colaborativa promueve la corrección a pares y la auto evaluación. Además, los estudiantes se sintieron más animados al escribir textos narrativos y su actitud positiva hacia la producción de historias aumentó; su conciencia metacognitiva hacía el proceso de escritura, sus compañeros y la auto-regulación dio como resultado a la aparición de conductas autónomas

Modeling Alternatives Sustainable-Energy-Policy for the Supply Chain of Wind Power in Brazil.

Renewable energy studies have received high attention in the last few years due the increasing deployment of alternatives such as wind, solar and biomass, as a result of the urgency in reducing fossil fuels consumption. This situation has involved an important challenge for long-term renewables policy and energy system planning. Brazil is the richest country in terms of renewable sources in Latin American. Brazil has energy generation portfolio not much different form the Colombia one, and the understanding of this very important country will contribute to inspire other countries in the region, particularly Colombia. Since 2004 the Brazilian energy policy promotes wind power development aimed at complementing hydropower generation. Despite the energy policies adopted in Brazil, the supply chain of wind power has experienced barriers that include: insufficient transmission lines and the delays in energy projects caused by lack synchronic among the energy policies. Thus, the unsynchronised energy policy has affected the performance of renewable energy supply chain, which has produced an impact on the electricity market. This thesis addresses these issues by evaluating alternative sustainable energy-policy, which must reflect new institutional guidelines to support wind power penetration and their dynamics performance in supply chain

Forensic Hydrology

This chapter is intended to call the attention towards a relatively new topic in engineering forensics: forensic analysis in hydrology. This type of analysis can be seen as a useful tool through which it is possible, in a fully objective way, to determine the real causes, natural or human induced that made a natural phenomenon a disaster. This branch of forensic analysis and particularly of engineering forensics can be applied directly to the case of floods and droughts but is not limited to those extremes phenomena. In particular, the application of these concepts to case of floods looks immediate, but other applications such as drought analysis can be addressed too. In the case of flooding events causing material damages and even loss of human lives, forensic analysis can provide results that help to clarify responsibilities but specially to prevent that future disasters happen again. This chapter will provide important information for the new forensic hydrologists, a discipline with great future, especially in the context of climate change, which will increase the magnitude, and frequency of extremes

Schools of the Street: Hip-hop as Youth Pedagogy in Bolivia

The experience of hip-hop in El Alto, Bolivia is at once familiar as it shares much of the sound, symbols and oppositional aspects with youth counterparts around the world, and also unique insofar as it takes on an explicit educational dimension. In El Alto, an environment where schools are scarce, poverty and unemployment rife, and mistrust of government and elite institutions widespread, the practice and culture of hip-hop seem to be fulfilling a role of popular, non-institutionalized public sphere education. Hip-hop has served as a means for youth to narrate their stories, write alternative histories, and act pedagogically and politically, especially during the political mobilizations in the past decade. Through life histories of two of the young men involved in popularizing hip-hop locally, this paper analyzes youth as public pedagogues and the streets, songs, and local cultural centers as public sphere schools

kNN-IS: an iterative spark-based design of the k-nearest neighbors classifier for big data

The k-Nearest Neighbors classifier is a simple yet effective widely renowned method in data mining. The actual application of this model in the big data domain is not feasible due to time and memory restrictions. Several distributed alternatives based on MapReduce have been proposed to enable this method to handle large-scale data. However, their performance can be further improved with new designs that fit with newly arising technologies. In this work we provide a new solution to perform an exact k-nearest neighbor classification based on Spark. We take advantage of its in-memory operations to classify big amounts of unseen cases against a big training dataset. The map phase computes the k-nearest neighbors in different training data splits. Afterwards, multiple reducers process the definitive neighbors from the list obtained in the map phase. The key point of this proposal lies on the management of the test set, keeping it in memory when possible. Otherwise, it is split into a minimum number of pieces, applying a MapReduce per chunk, using the caching skills of Spark to reuse the previously partitioned training set. In our experiments we study the differences between Hadoop and Spark implementations with datasets up to 11 million instances, showing the scaling-up capabilities of the proposed approach. As a result of this work an open-source Spark package is available

Plan de acción correos devueltos por el servidor respuesta cliente de la empresa claro Colombia S.A

Implementar un plan de acción que permita en la función de respuesta al cliente de la empresa Claro Colombia S.A, dar respuesta oportuna a las peticiones, quejas y reclamos de sus clientes cuyas respuestas enviadas por E-mail son rebotadas o devueltas por el servidor del correo del destinatarioEl servicio al cliente siempre ha existido a lo largo de la historia, buscando continuamente el objetivo de brindar un buen servicio y complacer todas las necesidades de los clientes, Cada día es mas la exigencia en el mercado de tener no solo un buen producto sino de tener un excelente servicio y atención al cliente debido que con este se tiene un trato y ambiente agradable con el cliente complaciéndolo en todos los aspectos y posiblemente fidelizándolo con la marca o producto seleccionado. Por ende, la responsabilidad de cuidar a los clientes se ha mantenido como una constante, pero el cómo se lleva eso a cabo ha cambiado de forma increíble. Cuando avanzamos a la edad del comercio moderno, nos damos cuenta de cómo el servicio de atención al cliente ha evolucionado siempre al calor de la tecnología (Carreño Jiménez, 2017). La compañía Claro Colombia S.A. en la gestión de los servicios que ofrece tiene direcciones, y cada una está dividida en áreas funcionales y áreas enfocadas en el servicio al cliente tales como, el área de facturación, cartera, reclamaciones, recaudo, cobranzas, protección al cliente, resoluciones, entre otras donde todas van encaminadas a un mismo objetivo y es el de dar solución a los problemas que presenten los clientes con el servicio prestado. En este plan de mejora que se implementó en la empresa Claro Colombia SA. en el área reclamaciones, en la función respuesta al cliente el cual es el encargado del envió de respuestas por vía correo electrónico, de las peticiones quejas y reclamos de los clientes, se evalúa el proceso y se plantea un plan de mejora a una problemática encontrada en el proceso el cual es en el momento del envió de respuestas a los clientes algunas respuestas no son enviadas exitosamente imposibilitando que el cliente reciba su comunicado por parte de la empresa. Teniendo en cuenta la problemática encontrada se propuso un plan de acción con estos correos que no son entregados, lo cual incurren a reprocesos en la empresa, y mala gestión en la calidad del proceso respuesta cliente, el plan de acción consiste en consolidar diario por medio de una base en Excel los datos de los clientes que no se les entrego efectivamente el correo, recolectar información por medio de las herramientas de la empresa, administrador de cliente y el gestor de peticiones quejas y reclamos y si es posible se contacta al cliente para recibir un correo alterno para ser enviada y entregada la comunicación efectivamente al cliente. Se hace el envió nuevamente de las respuestas y por últimos se hacen reportes e informes de los resultados de este plan de acción para así evaluar los resultados finales.Customer service has always existed throughout history, continuously seeking the goal of providing good service and satisfy all the needs of customers, Every day is more the requirement in the market to have not only a good product but to have an excellent service and customer service because with this we have a friendly and pleasant environment with the customer, satisfying him in all aspects and possibly fidelizing him with the Brand or selected product. Therefore, the responsibility of taking care of customers has remained a constant, but how this is done has changed in an incredible way. When we advance to the age of modern commerce, we realize how customer service has always evolved in the heat of technology (Carreño Jiménez, 2017). The company Claro Colombia S.A. in the management of the services offered, it has addresses, and each one is divided into functional areas and areas focused on customer service, such as the billing area, portfolio, claims, collection, collections, customer protection, resolutions, among others where all are aimed at the same goal and is to solve the problems that customers present with the service provided. In this improvement plan that was implemented in the company Claro Colombia SA. in the claims area, in the customer response function, which is in charge of sending replies via e-mail, of complaints and claims from customers, the process is evaluated and an improvement plan is proposed to a problem found in the process which is at the moment of sending responses to the clients, some answers are not sent successfully, making it impossible for the client to receive their communication from the company. Taking into account the problems encountered, an action plan was proposed with these emails that are not delivered, which incurs reprocessing in the company, and poor management in the quality of the customer response process, the action plan consists of consolidating daily by means of from a base in Excel the data of the clients who are not actually delivered the mail, collect information through the tools of the company, customer manager and the claims manager complaints and if possible contact the customer to receive an alternate email to be sent and delivered the communication effectively to the client. The replies are sent again and last reports and reports of the results of this action plan are made in order to evaluate the final results
