Preprocess and data analysis techniques for affymetrix DNA microarrays using bioconductor: a case study in Alzheimer disease

DNA microarray, or DNA chip, is a technology that allows us to obtain the expression level of many genes in a single experiment. The fact that numerical expression values can be easily obtained gives us the possibility to use multiple statistical techniques of data analysis. In this project microarray data is obtained from Gene Expression Omnibus, the repository of National Center for Biotechnology Information (NCBI). Then, the noise is removed and data is normalized, also we use hypothesis tests to find the most relevant genes that may be involved in a disease and use machine learning methods like KNN, Random Forest or Kmeans. For performing the analysis we use Bioconductor, packages in R for the analysis of biological data, and we conduct a case study in Alzheimer disease. The complete code can be found in https://github.com/alberto-poncelas/ bioc-alzheimer

Brand image and lexicographic analysis: an application to shopping malls

[EN] The concept of image in its different aspects is very important in today s society as well as in the business management field. Some authors reports that most of the studies that measure image do not take into account neither previous theoretical and conceptual models nor other possible empirical evidence alternatives. Given this need, a research regarding the concept of brand image applied to shopping malls was conducted based on the conceptual model of the consumer cognitive response in order to empirically explore and contrast it. For this reason, a survey was applied to 420 consumers in five shopping malls in Bogotá, achieving a database of 3.749 cases. The results show attribute-shopping mall associations expressed in unique, differentiated, and notorious vocabulary obtained applying lexicometric and multivariate analysis techniques. Attribute-shopping mall associations such as spacious , good location , good variety of stores , and the existence of movie theaters . Finally, this research aims to potentially improve the management of shopping malls and increase their attractiveness and customer loyalty by applying the development of service quality systems, integral communication, segmentation, and positioning.

La vivienda en la Comunidad Autónoma de Andalucia durante la reciente crisis inmobiliaria

[ES] En este trabajo se ha realizado un estudio del funcionamiento del mercado inmobiliario de la Comunidad de Andalucía en comparación con el territorio español durante el periodo 2000-2014. El presente análisis pretende dar una visión global de la situación del mercado inmobiliario e implícitamente del entorno económico en el último decenio y de las dificultades de acceso a una vivienda en la actualidad. La vivienda es un elemento relevante para la sociedad y la economía del país tanto en lo relacionado con el sector de la construcción como para el bienestar de las personas ya que supone la mayor inversión para la gran parte de las familias españolas. Se han llevado a cabo estudios de series de datos estadísticos de los diferentes indicadores y factores para ver los efectos que han tenido tanto en el periodo de boom como en la posterior crisis y exponer resultados y conclusiones en base a ello. La crisis ha generado un problema de carácter social relacionado con el mercado de la vivienda: el difícil acceso a una vivienda y los desahucios, que también se han abordado en este estudio y se han expuesto las políticas de ayuda que se están implantando en la Comunidad Andaluza.
