Book Description
Long after the Aztecs and the Incas had become a fading memory, a Maya civilization still thrived in the interior of Central America. Lost Shores, Forgotten Peoples is the first collection and translation of important seventeenth-century narratives about Europeans travelling across the great "Ocean Sea" and encountering a people who had maintained an independent existence in the lowlands of Guatemala and Belize. In these narratives--primary documents written by missionaries and conquistadors--vivid details of these little known Mayan cultures are revealed, answering how and why lowlanders were able to evade Spanish conquest while similar civilizations could not. Fascinating tales of the journey from Europe are included, involving unknown islands, lost pilots, life aboard a galleon fleet, political intrigue, cannibals, and breathtaking natural beauty. In short, these forgotten manuscripts--translations of the papers of the past--provide an unforgettable look at an understudied chapter in the age of exploration. Lost Shores, Forgotten Peoples will appeal to archaeologists, anthropologists, and historians interested in Central America, the Maya, and the Spanish Conquest.

Book Description
This diverse collection of research articles is united by the enormous power of modern molecular genetics. Every author accomplished two objectives: (1) making the field and the research described accessible to a large audience and (2) explaining fully the genetic tools and approaches that were used in the research. One fact stands out - the importance of a genetic approach to addressing a problem. I encourage you to read several chapters. You will feel the excitement of the scientists, and you will learn about an area of research with which you may not be familiar. Perhaps most importantly, you will understand the genetic approaches; and you will appreciate their importance to the research.

Book Description
Plant diseases, extreme weather caused by climate change, drought and an increase in metals in soil are amongst the major limiting factors of crop production worldwide. They devastate not only food supply but also the economy of a nation. Keeping in view of the global food scarcity, there is, an urgent need to develop crop plants with increased stress tolerance so as to meet the global food demands and to preserve the quality of our planet. In order to do this, it is necessary to understand how plants react and adapt to stress from the genomic and proteomic perspective. Plants adapt to stress conditions by activation of cascades of molecular mechanisms, which result in alterations in gene expression and synthesis of protective proteins/compounds. From the perception of the stimulus to transduction of the signal, followed by an appropriate response, the plants employ a complex network of primary and secondary messenger molecules. Cell signaling is the component of a complex system of communication that directs basic cellular activities and synchronizes cell actions. Cells exercise a large number of noticeably distinct signaling pathways to regulate their activity. In order to contend with different environmental adversities plants have developed a series of mechanisms at the physiological, cellular and molecular level. This two volume set takes an in-depth look at the Stress Signaling in Plants from a uniquely genomic and proteomics perspective. Stress Signaling in Plants offers a comprehensive treatise on the Chapter, covering all of the signaling pathways and mechanisms that have been researched so far. Each chapter provides in-depth explanation of what we currently know of a particular aspect of stress signaling and where we are headed. All authors have currently agreed and abstracts have been complied for the first volume, due out midway through 2012. We aim to have the second volume out at the beginning of 2013.

Book Description
Astroviruses were first identified in the feces of children in 1975. Since then, they have been found in ~ 3 to 20% of children with diarrhea. Given that serological studies have demonstrated that up to 90% of children have been exposed to at least one strain of astrovirus by age 9, the prevalence of infection may be much higher. Supporting this are studies demonstrating that astroviruses can also be isolated in a subset of asymptomatic individuals, suggesting that a proportion of infected individuals shed the virus asymptomatically or for some time after the resolution of other symptoms of infection. Asymptomatic carriers may be a major reservoir for astroviruses in the environment and could contribute to dissemination of the virus. Astroviruses are extremely stable in the environment and can be transmitted nosocomially, directly from infected individuals and potentially animals, and through contaminated food and water. Although typically an acute disease, astrovirus infection in premature infants may be associated with the development of necrotizing enterocolitis and in new-onset celiac disease in children. Immunocompromised children are even more susceptible often developing persistent infections that lead to wasting or even systemic infections associated with fatal encephalitis. In spite of its importance, little is known about astrovirus pathogenesis, molecular biology, epidemiology, or cell biology. The goal of this book is to provide the latest and most up-to-date information on this medically important and rapidly evolving group of viruses. It will include sections on the history of astroviruses and their disease in humans; information on viral replication and immune responses; new information on how astroviruses induce disease including the expression of a viral enterotoxin regulating intestinal epithelial cell tight junctions, the isolation and identification of new astrovirus genotypes in mammals including humans, and astroviruses of veterinary importance. Finally, the book will also introduce the complexity of astrovirus epidemiology and potential as an important new zoonotic disease, and its role in food-borne disease. This will be the first book of its kind and will be of great interest to microbiologists, virologists, infectious disease specialists, immunologists, pediatricians, public health and food safety experts, veterinarians, poultry industry specialists, and researchers and clinicians interested in enteritis.

Book Description
The decade since the publication of the third edition of this volume has been an era of great progress in biology in general and the plant sciences in particular. This is especially true with the advancements brought on by the sequencing of whole genomes of model organisms and the development of "omics" techniques. This fourth edition of Plant Roots: The Hidden Half reflects these developments that have transformed not only the field of biology, but also the many facets of root science. Highlights of this new edition include: The basics of root research and their evolution and role in the global context of soil development and atmosphere composition New understandings about roots gained in the post-genomic era, for example, how the development of roots became possible, and the genetic basis required for this to occur The mechanisms that determine root structure, with chapters on cellular patterning, lateral root and vascular development, the molecular basis of adventitious roots, and other topics Plant hormone action and signaling pathways that control root development, including new chapters on strigolactones and brassinosteroids Soil resource acquisition from agricultural and ecological perspectives Root response to stress, with chapters that address the impact of the genomic revolution on this topic Root-rhizosphere interactions, from beneficial microorganisms to detrimental nematodes Modern research techniques for the field and the lab Each chapter not only presents a clear summation of the topic under discussion, but also includes a vision of what is to be expected in the years to come. The wide coverage of themes in this volume continues the tradition that makes this work recognized as a fundamental source of information for root scientists at all levels.

Book Description
La OIT en el libro la reforma laboral en América latina: 15 años después, propuso el siguiente concepto en cuanto al contrato de trabaja en la región. UEI contrato de trabajo en las legislaciones de América latina es un acto constitutivo de obligaciones (es el acuerdo mismo de voluntades, con independencia de su forma, el que hace nacer las obligaciones) un negocio jurídico bilateral, de ejecución continuada en el tiempo (no se circunscribe a un solo momento, como el contrato de compra-venta, por ejemplo), que nace por la propia voluntad de las partes a \'obligarse a prestar un trabajo\', de un lado, y a remunerar el trabaja, del otro. En fin, el contrato de trabajo garantiza la libertad de trabajo reconocida en las Constituciones y dota a la relación individual de trabajo de un bagaje de condiciones mínimas". Desde cuando apareció este libro hasta hoy han pasado trece años, durante los cuales se vivió una crisis económica a escala internacional que ha generado una diversidad de enfoques sobre las políticas económicas y el paradigma de desarrollo; se han perdida por lo menos veinte millones de empleos en el mundo; se han incrementado las asimetrías entre lo económico y lo social y, gracias a la tecnología, han surgido múltiples opciones de trabajo virtual que han revolucionado la forma de trabajar y que demandan una reconfiguración de las normas laborales. Por esto, es más que pertinente cuestionarse sobre el papel del contrato de trabajo en la actualidad, en particular en los países de nuestra región, para lo cual se formuló un proyecto de investigación en el que se logró un trabajo colectivo de académicos de siete países y en el que se evidencian los desafíos que deben afrontar las legislaciones nacionales para conservar el ámbito de protección que da el contrato de trabajo, se explican los contenidos básicos de la legislación laboral frente a este y se hace una síntesis comparativa entre lo que hay en cada país, a fin de llamar a la reflexión y a la búsqueda de alternativas para que el derecho laboral no quede rezagado ante la que se ha llamado la cuarta revolución industrial.
