Book Description
La calidad de la información manejada por los sistemas computacionales es actualmente un área de preocupación que ha cobrado importancia en las empresas. La efectividad de los procesos de operación y toma de decisiones en una organización, dependen directamente de la calidad de los datos sobre los cuales se basan, por lo que una pobre calidad en la información, inevitablemente afectará los resultados de dichos procesos. Este trabajo de tesis propone una técnica de análisis de calidad de datos en bases de datos basada en reglas de integridad. Adicionalmente, con la finalidad de aprovechar las ventajas de las técnicas de aprendizaje automático, se hace uso de algoritmos de minería de datos, para generar en forma automatizada un conjunto de reglas de integridad, así como la detección de instancias que no cumplen dichas reglas de integridad. El proceso de minería de datos tiene la finalidad de obtener las reglas de integridad, respetando restricciones contextuales que puedan deducirse a partir de la misma información a analizar.

Book Description
The North American Mosaic has four overarching features. First, it is, to the extent feasible, based on comparable information on the status and trends of major indicators of the state of the environment in Canada,Mexico, and the United States. Second, the report confirms that these three countries together make up an incredibly complex, dynamic, and interconnected ecosystem in which humans play a dominant and decisive role. Third, the report raises important and sometimes disquieting questions concerning the sustainability of some current trends. Finally, the report is a reminder that our economic, social, and physical well-being are utterly dependent on the life-sustaining services provided by nature. This report emphasizes the importance of developing mutually compatible economic, social, and environmental goals and policies across the three-country region.

Book Description
Reflecting a global trend, scores of countries have affirmed that their citizens are entitled to healthy air, water, and land and that their constitution should guarantee certain environmental rights. This book examines the increasing recognition that the environment is a proper subject for protection in constitutional texts and for vindication by constitutional courts. This phenomenon, which the authors call environmental constitutionalism, represents the confluence of constitutional law, international law, human rights, and environmental law. National apex and constitutional courts are exhibiting a growing interest in environmental rights, and as courts become more aware of what their peers are doing, this momentum is likely to increase. This book explains why such provisions came into being, how they are expressed, and the extent to which they have been, and might be, enforced judicially. It is a singular resource for evaluating the content of and hope for constitutional environmental rights.

Book Description
This volume provides an unparalleled exploration of ethics and museum practice, considering the controversies and debates which surround key issues such as provenance, ownership, cultural identity, environmental sustainability and social engagement. Using a variety of case studies which reflect the internal realities and daily activities of museums as they address these issues, from exhibition content and museum research to education, accountability and new technologies, Museums, Ethics and Cultural Heritage enables a greater understanding of the role of museums as complex and multifaceted institutions of cultural production, identity-formation and heritage preservation. Benefitting from ICOM’s unique position in the museum world, this collection brings a global range of academics and professionals together to examine museums ethics from multiple perspectives. Providing a more complete picture of the diverse activities now carried out by museums, Museums, Ethics and Cultural Heritage will appeal to practitioners, academics and students alike.

Book Description
This volume presents both an analysis of how identities are built, represented and negotiated in narrative, as well as a theoretical reflection on the links between narrative discourse and identity construction. The data for the book are Mexican immigrants' personal experience narratives and chronicles of their border crossings into the United States. Embracing a view of identity as a construct firmly grounded in discourse and interaction, the author examines and illustrates the multiple threads that connect the local expression and negotiation of identity to the wider social contexts that frame the experience of migration, from material conditions of life in the United States to mainstream discourses about race and color. The analysis reveals how identities emerge in discourse through the interplay of different levels of expression, from implicit adherence to narrative styles and ways of telling, to explicit negotiation of membership categories.

Book Description
This publication provides an overview of the common and unique sustainability elements of Indigenous Peoples' food systems, in terms of natural resource management, access to the market, diet diversity, indigenous peoples’ governance systems, and links to traditional knowledge and indigenous languages. While enhancing the learning on Indigenous Peoples food systems, it will raise awareness on the need to enhance the protection of Indigenous Peoples' food systems as a source of livelihood for the 476 million indigenous inhabitants in the world, while contributing to the Zero Hunger Goal. In addition, the UN Decade of Action on Nutrition (2016-2025) and the UN Food Systems Summit call on the enhancement of sustainable food systems and on the importance of diversifying diets with nutritious foods, while broadening the existing food base and preserving biodiversity. This is a feature characteristic of Indigenous Peoples' food systems since hundreds of years, which can provide answers to the current debate on sustainable food systems and resilience.
