The article presents the results of an investigation that compared the views of the news media supervisors in Colombia and Puerto Rico on the skills they expect to be developed by journalism programs. Surveys with structured questions were administered, and a descriptive-comparative analysis was conducted. It was determined that supervisors in both countries consider important that the academy form journalists-generalists with digital and multimedia skills, who can produce for multiple platforms and master the skills traditionally associated with the profession. However, while those in Colombia think that the educational focus should be on developing critical thinking; those of Puerto Rico think that it should provide professional training. Both countries conceive that curricula should respond to the demands of the industry. [ABSTRACT FROM AUTHOR]

This literary review offers the results of documents published by international agencies, NGOs and academic work on human trafficking and Commercial Sexual Exploitation of Children (CSEC). In these documents issues such as: investigative trends, proposals for the prevention and the role of the media, were considered. The results confirm that between 2001 and so far in 2013, most researches in Colombia are associated to the study of trafficking of sexual exploitation, especially of children and women. There is less work developed on filial relationships (servile marriage and adoption for exploitation), commission of crimes (involvement in different crimes such as theft and drug transportation) and organ trafficking. This review has been made in order to provide a starting point for further research on the issues mentioned above. [ABSTRACT FROM AUTHOR]

This article shows research results aimed to characterize the strategies used by youth music radio stations in Bogota in order to maintain or to increase their audience from an emerging notion of musical consumption using audio portable devices. Therefore, in the first stage, semi-structured interviews were conducted among employees to five FM music radio stations in the city, with the aim to establish the strategies used by them. In a second moment, focal groups were developed with teenagers from 14 to 17 years old and young people from 21 to 25 years of age, in order to determine what drove them to listen to such music stations, if they had permanent access to the music they liked to listen to by using devices, like MP3, Ipod, and so on. The research showed that innovation in contents and interaction with listeners through social networks and other virtual channels are the stations' main strategies to attract listeners. At the same time, they said they listened to music stations because they show informative and subject novelties, and they also allow to open opinion exchange spaces using networks, and generate a sensation of closeness and affinity with the radio speakers.

El objetivo de este estudio fue evaluar el contenido de microelementos en suelo, pastos, hembras bovinas lecheras e indicadores reproductivos en vaquerías de la zona centro sur de la provincia Villa Clara. Se utilizaron cuatro unidades pecuarias representativas de la zona, dos vaquerías y dos centros de novillas, donde se estudiaron las características de la composición mineral del suelo, el pasto y el perfil mineral de los animales, incluidos órganos de reserva e indicadores reproductivos. Se calcularon los estadísticos descriptivos para todas las variables, los niveles de microelementos en el pasto en las dos épocas del año y entre vacas y novillas. En el suelo se encontraron 61,66,77 y 100 % de las muestras deficientes en Fe, Mn, Zn y Cu, respectivamente. En el pasto, durante el período lluvioso, se observaron deficiencias de Mn, Zn y Cu, en 38, 33 y 100 %, y durante el poco lluvioso de Mn y Cu en 27 y 100 % de las muestras. El 75 % de las muestras de suero sanguíneo eran deficientes en Cu y en tejido hepático. Se diagnosticaron 72,42 y 50 % de las muestras deficientes en Cu, Zn y Mn, respectivamente. Se concluye que en la zona de estudio la deficiencia mineral más acentuada fue la de Cu, diagnosticándose igualmente deficiencias de Zn y Mn, y un marcado deterioro de los indicadores reproductivos.

This paper shows a methodological proposal for the ordained use of the geological and mining heritage of Zaruma-Portovelo's district, in Ecuador, based in the experiences developed in Spain. The first step is to accomplish an inventory of the existing resources (geological and geomorphological features, former mining facilities, etc.) with a valuation of different aspects of them. The creation of a Geological Mining Park appears as the most viable frame of protection. To involve different administrations will be fundamental for the success of this project.

Se estudiaron 319 hembras bovinas lecheras, con cupremia espontánea (239) e inducida y/o provocada (80) para conocer la correlación entre los valores de la cupremia y los indicadores reproductivos. Se evaluó el riesgo relativo de la presentación de anestro y repetición de servicio en animales hipocuprémicos y en los suplementados con cobre (Cu). Se empleó la correlación y regresión simple para demostrar la relación del cobre con los indicadores reproductivos, y ANO VA para la comparación de las medias y comparaciones de proporciones para las presentaciones de celo y gestaciones. El riesgo relativo se evaluó mediante los paquetes Epidat 3.1 y Win Episcope 2.0. La hipocupremia aumentó 4.93,2.52 y 3.33 veces el riesgo de presentar anestro, repetición de servicio y problemas reproductivos totales, respectivamente. Se encontró una correlación negativa y significativa (P < 0.001) entre la cupremia e indicadores reproductivos en novillas y vacas, en un rango de 9.8 ± 1.0 a 14.0 ± 0.9 umo/L. Las dosis de 50 y 100 mg de Cu resultaron eficaces para incrementar la cupremia y mejorar los indicadores reproductivos. Mostraron además, efecto protector (P < 0.001) para el anestro y (P < 0.05) problemas reproductivos totales. Se concluye que existe una correlación negativa entre la hipocupremia y los indicadores reproductivos, aumentando el riesgo de presentar anestro, la repetición de servicio y los principales indicadores evaluados.

Introduction: Recent scientific studies show that gut microbiota may play an important role in the modulation of the body weight of the host. Objective: The aim of this article is to present an updated review of the scientific literature dealing with the potential roles of the gut microbiota and probiotics on the body weight of the host, including the predisposition to and prevention of overweight and obesity. Results and conclusions: The use of probiotics in different growth stages, both in human and animal hosts, is usually associated to a beneficial effect to the host's health. Admittedly, benefits associated to growth do not necessarily imply an increase in the adipose tissue or a predisposition to overweight or obesity. At present, the data that link the presence of specific gut microbial groups with obesity are controversial since it is unknown if they represent a cause or a consequence of obesity-associated diets and/or any other factor related to the pathogenesis of this condition. Studies dealing with the modulation of the gut microbiota to prevent or control obesity in the host, including the use of probiotics, are promising. In fact, probiotic intake in the mother-infant context might contribute to the control of the adult body weight by modulating the infant gut microbiota. However, well-designed randomized double-blind placebo-controlled trials are required to demonstrate the efficacy of specific probiotic strains for prevention or treatment of overweight and obesity. In the frame of the current obesity pandemics, use of probiotic strains with scientifically-substantiated properties against obesity risk factors may constitute a future approach, complementary to changes in diet and life style, for the modulation of the body weight.

Prehistoric caves represent cultural and tourist resources because of their archaeological, geological and geomorphological heritage. Geomorphologic mapping techniques have been applied to Tito Bustillo Cave (Ribadesella, Asturias, N Spain) during a research concerning the geotechnical stability of the cave. In this work, we present a methodology that includes: 1) Availability of a topography at a1: 250 scale. 2) A systematic and detailed inventory of endokarstic geomorphologic features. 3) Geomorphological mapping. 4) Digitalization of the geomorphological map and its transference to a GIS. 5) Quantitative managment of GIS derived information. A simple index (Iagc) is proposed to evaluate environmental impact on tourist caves in a scale ranging from 1 to 100, showing a value of 36,22 for the case of Tito Bustillo Cave.

This work shows the petrrographic and geochemical results obtained from the study of Asturian jet (Kimmeridgian, Jurassic) from Oles (Asturias, Northwestern Spain). By means of this research it was possible to determine the nature of this material, its composition and to explain its exceptional and anomalous properties. Asturian jet is a perhydrous coal, whose characteristics were promoted by the adsorption and retention of migrated hydrocarbons within its macromolecular structure in its early diagenetic stages. This gave rise to an anomalous evolution during the subsequent coalification processes. Moreover, the modification of its textural properties by the adsorbed hydrocarbons within the jet structure explains the great stability of this material which remains unaltered over long periods of time.
