Ni�os, j�venes y adolescentes: ellas, ellos y su m�vil
Los cambios sociales y tecnológicos que se están produciendo en los últimos años, influyen en las relaciones interpersonales, especialmente en las edades más tempranas y en la adolescencia. Como resultado de la presencia actual y predominante de los dispositivos móviles (ya sean teléfonos, tablets o pantallas, entre otros medios digitales) en la sociedad moderna, los docentes y las familias deben comenzar a dialogar sobre el uso adecuado de los mismos, así como de los valores éticos y ciudadanos que se proyectan hacia los niños y jóvenes. Porque la adquisición de dispositivos móviles, en las escuelas y en el hogar, presupone una aceptación tácita de los riesgos que ello puede generar.
Innovative Wastewater Treatment & Resource Recovery Technologies: Impacts on Energy, Economy and Environment
This book introduces the 3R concept applied to wastewater treatment and resource recovery under a double perspective. Firstly, it deals with innovative technologies leading to: Reducing energy requirements, space and impacts; Reusing water and sludge of sufficient quality; and Recovering resources such as energy, nutrients, metals and chemicals, including biopolymers. Besides targeting effective C,N&P removal, other issues such as organic micropollutants, gases and odours emissions are considered. Most of the technologies analysed have been tested at pilot- or at full-scale. Tools and methods for their Economic, Environmental, Legal and Social impact assessment are described. The 3R concept is also applied to Innovative Processes design, considering different levels of innovation: Retrofitting, where novel units are included in more conventional processes; Re-Thinking, which implies a substantial flowsheet modification; and Re-Imagining, with completely new conceptions. Tools are presented for Modelling, Optimising and Selecting the most suitable plant layout for each particular scenario from a holistic technical, economic and environmental point of view.
Food systems for an urbanizing world
Food Systems for an Urbanizing World is a joint report prepared by the World Bank and FAO. It aims to stimulate discussion and suggest pathways to support local and national governments, and civil society and private sector actors in their efforts to improve the performance and capacity of food systems. The report describes the diversity and ever-changing nature of food systems, with interlinked traditional, modern and informal channels that respond to different market segments and different consumer preferences. It also underscores the importance of targeting support to the type of city and food system. The task is not an easy one. Data are weak and empirical analysis is weaker. As cities’ engagement in urban food issues is relatively new, the institutions, governance mechanisms and capacities needed for effective design, implementation and delivery of this agenda must be strengthened. Finding effective ways to prioritize, mobilize and coordinate contributions from multiple sectors will be essential for achieving food system goals.
Criticism in the Borderlands
This pathbreaking anthology of Chicano literary criticism, with essays on a remarkable range of texts—both old and new—draws on diverse perspectives in contemporary literary and cultural studies: from ethnographic to postmodernist, from Marxist to feminist, from cultural materialist to new historicist. The editors have organized essays around four board themes: the situation of Chicano literary studies within American literary history and debates about the “canon”; representations of the Chicana/o subject; genre, ideology, and history; and the aesthetics of Chicano literature. The volume as a whole aims at generating new ways of understanding what counts as culture and “theory” a...
Pintura chilena contemporánea
Este volumen estudia la pintura en la Escuela de Arte de la Pontificia Universidad Católica de Chile, reuniendo el trabajo de más de 100 artistas. Se enumeran exposiciones en las que participaron y distinciones obtenidas, información acompañada por imágenes de sus obras. También se incluyen siete capítulos que contienen investigaciones organizadas a partir de dos criterios: uno temporal y otro conceptual. Las problemáticas detectadas por los siete investigadores organizan a los artistas presentados, que son agrupados según ejes articuladores de sentido presentes en sus obras.
Nutrition and livestock
This technical guidance brief summarizes some of the current thinking on how livestock can address the nutritional needs of vulnerable households and groups. It outlines recommendations for designing and implementing livestock interventions to leverage nutrition outcomes. It is intended for use by programme planners and managers working for government, humanitarian and development agencies involved in designing and implementing livestock-related policies and programmes, with the objective of helping in integration of nutrition outcomes in their work. Additionally, it is aimed at those involved in developing nutritional polices and strategies, to take into consideration the potential of livestock based strategies to improve nutrition.
