Book Description
El gráfico de control ha sido el método más usado en las últimas décadas para vigilar el comportamiento de una característica de calidad (X) asociada a un proceso productivo. A partir del trabajo fundamental de Duncan [Duncan 56], muchos modelos económicos se han desarrollado expresando el costo por hora del proceso (o también el costo por artículo producido) en función de los parámetros del gráfico, estos modelos permiten diseñar los parámetros de manera conveniente para minimizar los costos, los modelos consideran usualmente que el mecanismo de falla que explica la aparición de la causa (o causas) que descontrola(n) al proceso, tiene(n) tasa instantánea de falla constante (distribución exponencial), tal consideración simplifica y facilita la construcción matemática de los modelos económicos, sin embargo, ésta no es siempre una suposición realista, ya que en algunos procesos, con el desgaste de piezas, el calentamiento de máquinas u otros factores, el riesgo inminente de que se presente la causa que descontrola al proceso se puede incrementar con el tiempo (mecanismo con tasa instantánea de falla creciente). El presente trabajo propone un método para vigilar a un proceso, diferente al gráfico de control, en donde se realizan revisiones periódicas a intervalos iguales de tiempo, con la nueva forma de vigilancia es posible la construcción de un modelo económico básico que no está limitado a la suposición de un mecanismo de falla exponencial, permitiendo de manera más general que el mecanismo de falla sea Weibull. Los mecanismos de falla exponencial y Weibull son comparados en el modelo económico básico a través de 16 casos cuidadosamente elegidos, la comparación pone de manifiesto que la suposición clásica de un mecanismo de falla exponencial no es robusta y que puede haber un ahorro económico significativo si desde un principio el usuario del modelo acierta al considerar que el mecanismo de falla es Weibull en lugar de suponer que es exponencial.

Book Description
In today's "global village", nearly 450 million people speak English while another 350 million speak Spanish. The United States alone, with its more than 22 million Hispanic Americans, is now considered by many to be a bilingual society. As the practice of law and the resolution of legal issues, to a great extent, is all about precise communication, the impact of this on legal and business professionals is obvious - Spanish/English, English/Spanish translations are fast becoming an indispensable component of any thriving law practice or business, be it a small company or a multinational corporation. Translations are now routinely required for trials, contracts, real estate and financial transactions, and in many other situations. Clearly then, the need for a comprehensive bilingual reference such as this one has never been greater. Wiley's English/Spanish and Spanish/English Legal Dictionary offers comprehensive, up-to-date coverage of more than 40,000 essential words and phrases spanning all legal disciplines and subdisciplines including construction, real estate, insurance, business, trial, environmental law, intellectual property, family law, and more. It was written by a professional translator in collaboration with an advisory committee comprising attorneys from some of the most prominent firms in the international legal community. Featuring an extremely user-friendly format, the Dictionary was designed for quick reference. It directs you instantly to the precise equivalent you need without first "rerouting" you through a maze of other irrelevant terms and phrases. Gender neutral equivalents are provided, and in cases where the nongender neutral term is the norm, both are given.Wiley's English/Spanish and Spanish/English Legal Dictionary puts all important English and Spanish legal terms at the fingertips of attorneys, businesspeople, paralegals, and law students. It belongs on the shelves of law firms, libraries, businesses, and international agencies. It is also an essential communications tool for translators, interpreters, and civil servants.

Book Description
Mexican conservationists have sometimes observed that it is difficult to find a country less interested in the conservation of its natural resources than is Mexico. Yet, despite a long history dedicated to the pursuit of development regardless of its environmental consequences, Mexico has an equally long, though much less developed and appreciated, tradition of environmental conservation. Lane Simonian here offers the first panoramic history of conservation in Mexico from pre-contact times to the current Mexican environmental movement. He explores the origins of conservation and environmental concerns in Mexico, the philosophies and endeavors of Mexican conservationists, and the enactment of important conservation laws and programs. This heretofore untold story, drawn from interviews with leading Mexican conservationists as well as archival research, will be important reading throughout the international community of activists, researchers, and concerned citizens interested in the intertwined issues of conservation and development.

Book Description
A system plan is the design of a total reserve system covering the full range of ecosystems and communities found in a particular country, identifying the range of purposes of protected areas and the relationships among the system components (i.e., individual areas, protected areas and other land uses), and different sectors and levels of society. Highlighting key linkages with other aspects of economic development, it shows how various stakeholders can interact and cooperate to support effective and sustainable management of protected areas, and help to establish priorities. A valuable resource for all those involved with national system planning.

Book Description
Since 9/11, national governments in the global North have struggled to govern populations and manage cross-border traffic without building new barriers to trade. What does citizenship mean in an era of heightened tension between global capitalism and the nation-state? Building on Foucault's concept of biopolitics and an examination of national border and detention policies, Rygiel argues that citizenship is becoming a globalizing regime to govern mobility. The new regime is deepening boundaries based on race, class, and gender, and causing Western nations to embrace a more technocratic, depoliticized understanding of citizenship.

Book Description
Based on interviews with Leamington greenhouse growers and migrant Mexican workers, Tanya Basok offers a timely analysis of why the Seasonal Agricultural Workers Program is needed. She argues that while Mexican workers do not necessarily constitute cheap labour for Canadian growers, they are vital for the survival of some agricultural sectors because they are always available for work, even on holidays and weekends, or when exhausted, sick, or injured. Basok exposes the mechanisms that make Mexican seasonal workers unfree and shows that the workers' virtual inability to refuse the employer's demand for their labour is related not only to economic need but to the rigid control exercised by the Mexican Ministry of Labour and Social Planning and Canadian growers over workers' participation in the Canadian guest worker program, as well as the paternalistic relationship between the Mexican harvesters and their Canadian employers.
