Plataforma web y sistema integral de incentivos basado en el esquema de cupones online y el mercado de compras colectivas

En este trabajo se realiza una descripción y análisis del esquema de funcionamiento detrás del emergente mercado de las compras colectivas y los cupones online desde una perspectiva tanto teórica como empírica. Inicialmente, se desarrolla un marco teórico teniendo en cuenta elementos de: teoría económica, e-marketing y comercio electrónico en los que se basa éste mercado. Posteriormente, se muestra el proyecto de implementación de una plataforma virtual y un sistema de incentivos basado en el esquema de cupones online desarrollado por el autor para la franquicia de tarjetas de crédito Diners Club International del Banco Davivienda S.A. en Colombia

OpenSearch-geo: the simple standard for geographic web search engines

When publishing information on the web, one expects it to reach all the people that could be interested in. This is mainly achieved with general purpose indexing and search engines like Google which is the most used today. In the particular case of geographic information (GI) domain, exposing content to mainstream search engines is a complex task that needs specific actions. In many occasions it is convenient to provide a web site with a specially tailored search engine. Such is the case for on-line dictionaries (wikipedia, wordreference), stores (amazon, ebay), and generally all those holding thematic databases. Due to proliferation of these engines, A9.com proposed a standard interface called OpenSearch, used by modern web browsers to manage custom search engines. Geographic information can also benefit from the use of specific search engines. We can distinguish between two main approaches in GI retrieval information efforts: Classical OGC standardization on one hand (CSW, WFS filters), which are very complex for the mainstream user, and on the other hand the neogeographer’s approach, usually in the form of specific APIs lacking a common query interface and standard geographic formats. A draft ‘geo’ extension for OpenSearch has been proposed. It adds geographic filtering for queries and recommends a set of simple standard response geographic formats, such as KML, Atom and GeoRSS. This proposal enables standardization while keeping simplicity, thus covering a wide range of use cases, in both OGC and the neogeography paradigms. In this article we will analyze the OpenSearch geo extension in detail and its use cases, demonstrating its applicability to both the SDI and the geoweb. Open source implementations will be presented as well

Utilización y aplicación de la herramienta "google docs" en la docencia universitaria dentro del marco del EEES

Como consecuencia de la realización del curso 'Aplicaciones de la Web 2.0 en la Investigación y la Docencia' organizado por La Fundación General Universidad de Granada-Empresa en el curso académico 2009-2010, los autores del presente trabajo presentamos el Proyecto de Innovación Docente concedido por el Vicerrectorado para la Garantía de la calidad de la Universidad de Granada,titulado 'Utilización de la herramienta “Google Docs” en la Docencia Universitaria dentro del marco del EEES. Creemos que el proyecto tiene un diseño aplicable a cualquier asignatura de la actual Licenciatura y/o Grado de Farmacia. En este trabajo se expone la experiencia piloto llevada a cabo en la asignatura de Química Farmacéutica, incluyendo el desarrollo, objetivos, metodología, resultados y las conclusiones que se están obteniendo en el trascurso del mismo

Un estudi de casos sobre l'avaluació del resultat de l'aprenentatge a l'E.S.O.: una base per a la reflexió i la formació del professorat

This study is built up on the need to enhance the thinking over the decisions taken and the performances carried out by teachers and students in secondary education with regard to the evaluation of the learning result. The problem lies in that the information and - or - the results gathered from the evaluation practices do not always entail a serious consideration of these data. Hence the lack of a systematic modification of the educational practices. In this study a range of self-questioning tools are proposed in order to enhance ¡the teachers and students' ability to think about this topic as well as their ability to evaluate themselves. The proceeding has been the following: a) the issues that generate conflict have been identified according to the dimensions and categories of this research; b) a model to build the tools has been elaborated; c) finally, questions have been constructed for each one of the conflicts previously specified. This has been done bearing in mind the theoretical framework that has been chosen to carry out this research. The mechanism that is proposed here is formed by five tools for the teachers and one for the students. Each tool consists of a) the definition of the problem; b) the goal of the tool, and c) the three levels of consideration. In the first level, general questions are put forward in order to be discussed either individually or in a group. The goal of this activity is to gain consciousness of the key issues in order to solve the problems. In the second level, a more structured guide is proposed. Its goal is to direct the practice of the reflection of the issues that generate a conflict. Finally, in the third level, a method is proposed to increase the reflection and the viewpoints of this reflection, like written documents, web pages, specific references, experiences, and opinions about the topic.

Validation of ocean model syntheses against hydrography using a new web application

Results are presented from a new web application called OceanDIVA - Ocean Data Intercomparison and Visualization Application. This tool reads hydrographic profiles and ocean model output and presents the data on either depth levels or isotherms for viewing in Google Earth, or as probability density functions (PDFs) of regional model-data misfits. As part of the CLIVAR Global Synthesis and Observations Panel, an intercomparison of water mass properties of various ocean syntheses has been undertaken using OceanDIVA. Analysis of model-data misfits reveals significant differences between the water mass properties of the syntheses, such as the ability to capture mode water properties.

Analysing Google rankings through search engine optimization data

Purpose - The purpose of this paper is to identify the most popular techniques used to rank a web page highly in Google. Design/methodology/approach - The paper presents the results of a study into 50 highly optimized web pages that were created as part of a Search Engine Optimization competition. The study focuses on the most popular techniques that were used to rank highest in this competition, and includes an analysis on the use of PageRank, number of pages, number of in-links, domain age and the use of third party sites such as directories and social bookmarking sites. A separate study was made into 50 non-optimized web pages for comparison. Findings - The paper provides insight into the techniques that successful Search Engine Optimizers use to ensure a page ranks highly in Google. Recognizes the importance of PageRank and links as well as directories and social bookmarking sites. Research limitations/implications - Only the top 50 web sites for a specific query were analyzed. Analysing more web sites and comparing with similar studies in different competition would provide more concrete results. Practical implications - The paper offers a revealing insight into the techniques used by industry experts to rank highly in Google, and the success or other-wise of those techniques. Originality/value - This paper fulfils an identified need for web sites and e-commerce sites keen to attract a wider web audience.
