A Survey on Privacy in Location-Based Services

Abstract: Location services have become popular over the last years due to the global adoption of smartphones and the worldwide availability of the Global Positioning System (GPS) and other positioning methods. Location-based services (LBSs) offer relevant information to users based on their location. Some common applications of LBSs are traffic or public transportation information, search of points of interest (restaurants, stores, etc.), navigation, among others. Despite all the desirable features that these services provide, most of them do not provide adequate protection of the geographical location of the users, putting them at risk if their information falls in wrong hands. This paper presents a compendium of techniques to protect the location privacy of the users, and introduces an approach to compare and evaluate the presented mechanisms and their viability to be used in different kinds of LBSs.

Impact of an Educational Program to Reduce Healthcare Resources in Community-Acquired Pneumonia: The EDUCAP Randomized Controlled Trial.

Abstract: Background Additional healthcare visits and rehospitalizations after discharge are frequent among patients with community-acquired pneumonia (CAP) and have a major impact on healthcare costs. We aimed to determine whether the implementation of an individualized educational program for hospitalized patients with CAP would decrease subsequent healthcare visits and readmissions within 30 days of hospital discharge.

Mujer, espacio y poder: ciudad y transporte público como dispositivos de exclusión. Reflexiones desde la ciudad de Cali.

Abstract: Este trabajo presenta los resultados del estudio de caso del transporte informal de las comunas 15 y 18 de la ciudad de Cali. El transporte informal ha sido trabajado como una de las constantes en las ciudades latinoamericanas. En la literatura, este fenomeno se relaciona como un efecto de la implementacion de las politicas neoliberales de privatizacion de los sistemas de transporte o como una evidencia de la incapacidad de la Administracion publica y del Estado para hacerse cargo de su espacio de soberania. Este trabajo problematiza estos diagnosticos y sugiere una nueva manera de abordar el transporte informal en las urbes del sur global. Con tecnicas etnograficas, el trabajo muestra como la informalidad es un espacio socialmente construido con tres caracteristicas principales: a) la persistencia de hombres prestadores del servicio y mujeres usuarias, ambos de bajos ingresos economicos, solidarios entre si para resistir ante un sistema oficial que los excluye; b) el uso significativo de esta clase de transportes de mujeres de estratos bajos que necesitan movilizarse, de manera flexible y economica, de zonas alejadas de los centros productivos, excluidos de los disenos de rutas de transporte, y c) la burocratizacion de las practicas asociadas con la prestacion del servicio informal. Estos hallazgos permiten sostener que los espacios urbanos son construcciones sociales que, al estar cruzadas por vectores de poder como el genero, hacen que la experiencia geografica de hombres y mujeres sea diferenciada.
