Derechos de la infancia en la era digital

La brecha digital exacerba desigualdades en el acceso a información y conocimiento, socialización con pares, visibilidad y manejo de herramientas básicas para desempeñarse en la sociedad. Reducir esta brecha permite sinergias virtuosas de inclusión social y cultural entre niños, niñas y adolescentes, con impactos positivos en el desarrollo de capacidades y generación de oportunidades para toda su vida. Si bien las nuevas generaciones están conectadas y sus miembros son nativos digitales, persisten desigualdades entre grupos socioeconómicos, aun cuando se han reducido gracias a los programas de conectividad en las escuelas públicas de la región. El artículo central de esta edición de Desafíos aborda –con información actualizada– las brechas y los avances en esta materia. El acceso es solo un primer paso; luego, es necesario proteger a niños y adolescentes contra los riesgos de la conectividad y potenciar los aprendizajes pertinentes y plenos de sentido, promoviendo usos más articulados con el currículo educativo. Por último, el artículo plantea que hay que vincular las políticas de conectividad con el cumplimiento de los derechos de la infancia en el marco de la Convención sobre los Derechos del Niño. Junto al artículo central, y como es habitual, se informa de encuentros y conferencias en la región durante el año y de publicaciones recientes en la materia. También se presentan buenas prácticas en el Perú para reducir brechas de género y una iniciativa conjunta de los operadores móviles y el UNICEF para proteger a la infancia en la era digital. En Puntos de vista se incluye la opinión de especialistas acerca de la potencialidad de las TIC como una herramienta a tener en cuenta para el ejercicio o vulneración de los derechos de niños, niñas y adolescentes.

Quality management, environmental management maturity, green supply chain practices and green performance of Brazilian companies with ISO 14001 certification: Direct and indirect effects

This study aims to test a new conceptual model based on the relationship between quality management (QM), environmental management maturity (EMM), adoption of external practices of green supply chain management (GSCM) (green purchasing and collaboration with customers) and green performance (GP) with data from 95 Brazilian firms with ISO 14001. To our knowledge, such links and relationships are not simultaneously identified and tested in the literature. The results indicate the validation of all of the research hypotheses. This paper highlights that an improvement in green performance will require attention to quality management, environmental management maturity, and green supply chain. (C) 2014 Elsevier Ltd.

Energy Management and Control for Islanded Microgrid Using Multi-Agents

This paper presents a multi-agent system for real-time operation of simulated microgrid using the Smart-Grid Test Bed at Washington State University. The multi-agent system (MAS) was developed in JADE (Java Agent DEvelopment Framework) which is a Foundation for Intelligent Physical Agents (FIPA) compliant open source multi-agent platform. The proposed operational strategy is mainly focused on using an appropriate energy management and control strategies to improve the operation of an islanded microgrid, formed by photovoltaic (PV) solar energy, batteries and resistive and rotating machines loads. The focus is on resource management and to avoid impact on loads from abrupt variations or interruption that changes the operating conditions. The management and control of the PV system is performed in JADE, while the microgrid model is simulated in RSCAD/RTDS (Real-Time Digital Simulator). Finally, the outcome of simulation studies demonstrated the feasibility of the proposed multi-agent approach for real-time operation of a microgrid.

Survey of the nutritional recommendations and management practices adopted by feedlot cattle nutritionists in Brazil

Thirty-three feedlot cattle nutritionists were surveyed to evaluate the management practices and nutritional recommendations adopted by feedlots in Brazil. The web-based survey consisted of 81 questions that included: general information (n = 10); general commodity information (n = 15); use of coproducts (n = 5), roughage source and level (n = 5); adaptation methods (n = 7); feed mixers (n = 6); feeding management (n = 6); cattle management and type of cattle fed (n = 13); formulation practices (n = 9); information resources used for nutritional recommendations (n = 2); and additional questions (n = 3). In total, the 33 nutritionists were responsible for approximately 2,658,000 animals, and moreover, 65.5% of those participants had clients that feed less than 5000 animals yearly. Corn was the primary source of grain used in feedlot diets (87.9%) and cracking was the primary processing method recommended by nutritionists (57.6%). The average concentrate and roughage inclusion in finishing diets was 79.0% and 21.0%, respectively. The main challenges faced by nutritionists are the lack of available and precise equipment and lack of trained employees with respiratory diseases as the main health problem. This survey of nutrition and management practices should aid in the development of research for the feedlot industry in Brazil and similar tropical climates, as well as provide data to facilitate the broader application of future NRC models.

A multiple intelligences theory-based 3D virtual lab environment for digital systems teaching.

This paper describes a 3D virtual lab environment that was developed using OpenSim software integrated into Moodle. Virtuald software tool was used to provide pedagogical support to the lab by enabling to create online texts and delivering them to the students. The courses taught in this virtual lab are methodologically in conformity to theory of multiple intelligences. Some results are presented.
