The statistical analysis of compositional data should be treated using logratios of parts, which are difficult to use correctly in standard statistical packages. For this reason a freeware package, named CoDaPack was created. This software implements most of the basic statistical methods suitable for compositional data. In this paper we describe the new version of the package that now is called CoDaPack3D. It is developed in Visual Basic for applications (associated with Excel©), Visual Basic and Open GL, and it is oriented towards users with a minimum knowledge of computers with the aim at being simple and easy to use. This new version includes new graphical output in 2D and 3D. These outputs could be zoomed and, in 3D, rotated. Also a customization menu is included and outputs could be saved in jpeg format. Also this new version includes an interactive help and all dialog windows have been improved in order to facilitate its use. To use CoDaPack one has to access Excel© and introduce the data in a standard spreadsheet. These should be organized as a matrix where Excel© rows correspond to the observations and columns to the parts. The user executes macros that return numerical or graphical results. There are two kinds of numerical results: new variables and descriptive statistics, and both appear on the same sheet. Graphical output appears in independent windows. In the present version there are 8 menus, with a total of 38 submenus which, after some dialogue, directly call the corresponding macro. The dialogues ask the user to input variables and further parameters needed, as well as where to put these results. The web site http://ima.udg.es/CoDaPack contains this freeware package and only Microsoft Excel© under Microsoft Windows© is required to run the software.

A recent study defines a new network plane: the knowledge plane. The incorporation of the knowledge plane over the network allows having more accurate information of the current and future network states. In this paper, the introduction and management of the network reliability information in the knowledge plane is proposed in order to improve the quality of service with protection routing algorithms in GMPLS over WDM networks. Different experiments prove the efficiency and scalability of the proposed scheme in terms of the percentage of resources used to protect the network

"Internet for Image Searching" is a free online tutorial to help staff and students in universities and colleges to find digital images for their learning and teaching. The emphasis of the tutorial is on finding copyright cleared images which are available free; facilitating quick, hassle-free access to a vast range of online photographs and other visual resources. "This tutorial is an excellent resource for anyone needing to know more about where and how to find images online. The fact that it concentrates on copyright cleared images will make it even more valuable for busy learning and teaching professionals, researchers and students alike. It will also serve to inspire confidence in those needing to use images from the web in their work." (Sharon Waller of the Higher Education Academy).

Se describe la iniciativa actual que realiza la Universidad Nacional Autónoma de México (UNAM) en torno a la administración de sus acervos digitales. Se presenta el modelo de manejo de recursos digitales y sus tres principales divisiones: publicaciones formales, páginas institucionales y otros recursos (literatura gris y bases de datos). Posteriormente se detallan tres proyectos específicos dentro de este marco: RAD repositorio institucional de la UNAM, sistema de revistas digitales UNAM y UNIBIO (Unidad de Informática para la Biodiversidad). Por último se describen los principales retos a futuro, principalmente la importancia del cabildeo con autoridades universitarias acerca del valor de la correcta administración de recursos digitales, la necesidad de desarrollar indicadores más eficientes para medir producción, impacto y visibilidad de recursos digitales y temas relacionados con el mantenimiento y preservación de los mismos.

Los objetivos de este estudio fueron proveer datos con respecto a los patrones de infección de seis tipos de Papilomavirus humano de Alto Riesgo (AR-VPH-16, -18, -31, -33, -45, y -58) y dos tipos de Bajo Riesgo BR-VPH- 6 and -11), su asociación con factores de riesgo y coinfección. Se probaron muestras cervicales de 2110 mujeres para evaluar la presencia de DNA de HPV por reacción en cadena de la polimerasa. Se realizaron análisis estadísticos para determinar las frecuencias de los tipos virales encontrados en infecciones únicas y múltiples y la asociación entre infección y diferentes factores poblacionales. El tipo más prevalente fue VPH-16 seguido de VPH-31, siendo la distribución de éste último, variable según las diferentes ciudades analizadas. Los resultados evidenciaron una distribución tipo-específica diferencial entre regiones y una alta asociación entre ausencia de embarazos, ciudades como Girardot y Leticia, pertenecer a la etnia indígena (analizada en este estudio) y la adquisición de infecciones múltiples. Adicionalmente los datos sugieren que algunos factores sociodemográficos como la raza, el número de embarazos, el número de compañeros sexuales y la región geográfica se asocian significativamente y mostraron diferencias menores entre infecciones únicas y múltiples. Estos resultados proveen información relevante que permitirá evaluar el impacto de los programas de vacunación en estas poblaciones y la presión selectiva que podría tener la distribución de los tipos de VPH.

El mercado de valores ofrece una variedad de activos con diferentes combinaciones de rendimientos y de riesgos que en la actualidad las empresas utilizan, con el fin de obtener rendimientos o dividendos y contribuir a aumentar el capital de la empresa. Esta operación, si no es realizada de manera correcta puede generar desde la falta de liquidez hasta la pérdida de dinero. Por tal motivo, la creación de portafolios de inversión se convierte en una herramienta fundamental para la toma de decisiones permitiéndole a las empresas que los remanentes de tesorería sean utilizados como inversión y que estos mismos obtengan rendimientos fructíferos y satisfactorios.
