Uso problemático de las redes sociales en estudiantes universitarios

Los avances que están produciéndose en el ámbito académico con el surgimiento de herramientas de la Web 2.0 y el empleo masivo por parte de los estudiantes de la redes sociales para comunicarse entre ellos, está haciendo que el panorama educativo se encuentre ante unos desafíos a los que tiene que dar respuesta. La investigación que aquí se presenta tuvo como objetivo principal analizar el estado del empleo de la redes sociales por parte alumnado universitario, así como los posibles malos hábitos y usos problemáticos de las mismas. Se utilizó como instrumento de recogida de información un cuestionario “ad hoc” con un total de 23 ítems. Se concluye que el alumnado en general no posee malos hábitos en el empleo de las redes sociales, igualmente los resultados obtenidos ponen de manifiesto que su utilización no está plenamente integrada en las instituciones universitarias de educación superior, así como que los estudiantes no las emplean/usan como herramienta fundamental para las resolución de cuestiones académicas.

Talde-identifikazioa, barne-taldearekiko faboritismoa eta hautemandako homogeneotasun-maila testuinguru soziopolitiko desberdinetan garatzen ari diren haur eta nerabeengan

Aquest treball presenta una investigació que explora la construcció social de la identitat nacional en 922 nens de 6, 9, 12 i 15 anys d’edat que creixen en diferents contextos socio-polítics i lingüístics. Els resultats mostren diferències en el favoritisme en grups en funció de la identificació subjectiva, però no en percepció d’homogeneïtzació, que no canvia en tots els contextos socio-polítics

El dilema de la política exterior de la España nacionalista hacia la Alemania nazi: una estrategia de cooperación militar y de diplomacia secreta (1936 - 1945)

RESUMEN El interés de este estudio de caso es explicar de qué manera la España de Francisco Franco logra articular en su Política Exterior dos importantes estrategias, la cooperación militar y la diplomacia secreta, hacia la Alemania de Adolf Hitler desde el estallido de la Guerra Civil española en 1936 hasta el final de la Segunda Guerra Mundial en 1945. Se identifican las características de esta Política Exterior en la medida que se conocen los aspectos más importantes de la relación bilateral hispano-alemán, para así explicar cómo la articulación de estas posturas estratégicas le permitieron al Caudillo lograr sus objetivos políticos y, al mismo tiempo, salir indemne de esta Guerra. De esta forma, la perspectiva teórica del Realismo de las Relaciones Internacionales permite identificar las variables más importantes de la Política Exterior de España hacia Alemania a medida que Franco va definiendo su Interés Nacional.

Wasted: understanding the economic and social impact of food waste

Over one-third of global food production goes to waste while over 850million people are fighting chronic hunger. The United States is the world’s largest food waster. One third of America’s food with an economic value of US$161 billion is wasted and less than 7% is recycled. American food waste ends up in landfills creating powerful methane gas emissions. South Korea, on the other hand, has implemented the world’s strictest food waste laws, and today diverts 93% of wasted food away from landfills turning such waste into powerful economic opportunities. This Master Thesis investigates the reasons behind global food waste by comparing South Korea and the US. It explores what these two nations are doing to address their respective food waste problems, South Korea successfully, the US not. The paper looks at the two countries’ respective policies and national characteristics, which impact decision-making and recycling processes. The effort concludes that South Korea has embarked on a necessary paradigm shift turning food waste into powerful economic drivers leading to a sharp decline in food waste. In the US, food waste continues to be a major problem without a national strategy to remedy waste. Any effort in the US, while laudable, is sporadic and local, and hence the US misses out on possibly important economic growth opportunities.

As câmaras municipais brasileiras: perfil de carreira e percepção sobre o processo decisório local

Neste artigo, o legislativo municipal é analisado a partir de dois eixos: (1) a ênfase em suas características nacionais e regionais, com base em dados sobre a composição social e político-partidária do legislativo municipal no Brasil, no período de 1996, 2000 e 2004; e (2) os diferentes modos como os poderes legislativos locais de São Paulo e Santa Catarina percebem os poderes executivos no que se refere ao processo decisório.

A feasibility study for the provision of electronic healthcare tools and services in areas of Greece, Cyprus and Italy

Background Through this paper, we present the initial steps for the creation of an integrated platform for the provision of a series of eHealth tools and services to both citizens and travelers in isolated areas of thesoutheast Mediterranean, and on board ships travelling across it. The platform was created through an INTERREG IIIB ARCHIMED project called INTERMED. Methods The support of primary healthcare, home care and the continuous education of physicians are the three major issues that the proposed platform is trying to facilitate. The proposed system is based on state-of-the-art telemedicine systems and is able to provide the following healthcare services: i) Telecollaboration and teleconsultation services between remotely located healthcare providers, ii) telemedicine services in emergencies, iii) home telecare services for "at risk" citizens such as the elderly and patients with chronic diseases, and iv) eLearning services for the continuous training through seminars of both healthcare personnel (physicians, nurses etc) and persons supporting "at risk" citizens. These systems support data transmission over simple phone lines, internet connections, integrated services digital network/digital subscriber lines, satellite links, mobile networks (GPRS/3G), and wireless local area networks. The data corresponds, among others, to voice, vital biosignals, still medical images, video, and data used by eLearning applications. The proposed platform comprises several systems, each supporting different services. These were integrated using a common data storage and exchange scheme in order to achieve system interoperability in terms of software, language and national characteristics. Results The platform has been installed and evaluated in different rural and urban sites in Greece, Cyprus and Italy. The evaluation was mainly related to technical issues and user satisfaction. The selected sites are, among others, rural health centers, ambulances, homes of "at-risk" citizens, and a ferry. Conclusions The results proved the functionality and utilization of the platform in various rural places in Greece, Cyprus and Italy. However, further actions are needed to enable the local healthcare systems and the different population groups to be familiarized with, and use in their everyday lives, mature technological solutions for the provision of healthcare services.
