With over 1800 species, Peru has the second richest avifauna of any country in the world. As a consequence it is one of the most popular birding destinations in South America. This will be the first comprehensive and fully illustrated field guide to the birds of Peru. Text is arranged opposite the plates, in conventional field guide manner. The combination of authoritative text and superb artwork will set new standards for South American field guides.

From reviews of the previous edition

"The island nation of Trinidad and Tobago has long served as a window on South American birdlife. Birders have been visiting the two islands in large numbers since the 1960s, when Asa Wright converted an unproductive plantation into one of the first neotropical 'ecotourist traps.' Anyone traveling to Trinidad and Tobago shouldn't leave home without this work." Journal of Field Ornithology

"This book will be wanted by any birder visiting Trinidad and Tobago, as well as by many ornithologists as a general reference." Wilson Bulletin

Members of nearly all the families of South American birds can be found on the two beautiful West Indian islands of Trinidad and Tobago, where the pleasant climate, varied habitat, and avian diversity create a "birder's paradise." This easy-to-use book is the third edition of a comprehensive yet compact field guide to all 477 species of the islands' birds, including 35 new species accounts added to the country's bird list since the last edition. Richard ffrench s work has been a "bible" to birders since the appearance of the first edition in 1973. This new edition incorporates five decades of his notes and records of the island s birds to present in a handy and readable form detailed and comprehensive information about the birds of Trinidad and Tobago.

Showcasing 40 all-new color plates by the very best bird artists working under the direction of John P. O Neill, the third edition now includes illustrations of not only the islands endemic and resident species, but also the many migratory species that visit the islands from both the north and the south. The taxonomic arrangement and treatment of families and species has also been brought in line with the most recent determinations of the A.O.U. Committee on Nomenclature for a thoroughly up-to-date presentation. In his introduction, Richard ffrench offers a full treatment of the history of ornithology in Trinidad and Tobago and sets the scene by describing the islands physiography, climate, and vegetation. Individual species accounts, arranged by family, make up the core of this identification guide. The accounts cover habitat and status, range and subspecies, field description and basic measurements, voice, food, nesting, and behavior. Richard ffrench s summary of the distribution of species and their breeding and migration, as well as local conservation and protection measures, makes this volume much more than a typical field-guide treatment, and invites visitors to this premier ecotourism destination."

Over the years, the electric power industry has been using optimization methods to help them solve the unit commitment problem. The result has been savings of tens and perhaps hundreds of millions of dollars in fuel costs. Things are changing, however. Optimization technology is improving, and the industry is undergoing radical restructuring. Consequently, the role of commitment models is changing, and the value of the improved solutions that better algorithms might yield is increasing. The dual purpose of this book is to explore the technology and needs of the next generation of computer models for aiding unit commitment decisions. Because of the unit commitment problem's size and complexity and because of the large economic benefits that could result from its improved solution, considerable attention has been devoted to algorithm development in the book. More systematic procedures based on a variety of widely researched algorithms have been proposed and tested. These techniques have included dynamic programming, branch-and-bound mixed integer programming (MIP), linear and network programming approaches, and Benders decomposition methods, among others. Recently, metaheuristic methods have been tested, such as genetic programming and simulated annealing, along with expert systems and neural networks. Because electric markets are changing rapidly, how UC models are solved and what purposes they serve need reconsideration. Hence, the book brings together people who understand the problem and people who know what improvements in algorithms are really possible. The two-fold result in The Next Generation of Electric Power Unit Commitment Models is an assessment of industry needs and new formulations and computational approaches that promise to make unit commitment models more responsive to those needs.

Interest in the biological effects of ionising radiation closely followed the identification of such radiation. The realisation that DNA is the site of genetic infonnation in cells subsequently focussed attention on DNA as an important target in the lethal and mutagenic effects of ionising radiation. Thus radiation effects upon DNA became an important area for fundamental scientific studies by radiation biologists, chemists and physicists. To a first approximation, the concerns of the three disciplines can be divided by time scales: the physical process of energy deposition from photon or charged 16 12 particle and subsequent relaxation (-10- to 10- secs), followed by chemical 12 2 reactions (- 10- to 10 secs), and fmally, the expression of biological effect (minutes to years). Thus, the concept of 'early processes' conveys different ideas to different scientists, although they are all interrelated. To attempt to describe in any detail all these processes is a mammoth task which is not made easier by the different conventions and experimental approaches of the three disciplines. However, the recent advances in all these scientific areas seemed, to the organisers at least, to offer the opportunity to stimulate more active interaction between physicists, chemists and biologists. With this in mind, a multi-disciplinary workshop was organised, which brought together some fifty scientists to present their own specialist interests and, through extensive discussion, explore which problems are of high priority and require input from the different disciplines to resolve them.

For centuries, African and Irish people have traversed the Atlantic, as slaves, servants, migrants, exiles, political organizers and cultural workers. Their experiences intersected; their cultures influenced one another. These essays explore the connections that have defined the 'Black and Green Atlantic' in culture, politics, race and labour.

The Anglo-Norman world, with particular focus on the Normans in Ireland. Founded by Professor R. Allen Brown, the Battle Conference this year celebrates its 20th meeting in Dublin with a particular focus on Irish topics. Anglo-Norman Studies, published annually and containing the papers presented at the conference, is established as the single most important publication in the field (as a glance at bibliographies of the period will confirm), covering not only matters relating to pre- and post-Conquest England and France,but also the activities and influences of the Normans on the wider European, Mediterranean, and Middle Eastern stage.

The Latin psalms figured prominently in the lives of the Anglo-Saxons, whether sung in the Divine Office by clerics, studied as a textbook for language learning by students, or recited in private devotion by lay people. They were also translated into Old English, first in prose and later in verse. Sometime in the middle of the eleventh century, the prose and verse translations were brought together and organized in a complementary sequence in a manuscript now known as the Paris Psalter. The prose version, traditionally attributed to King Alfred (d. 899), combines literal translation with interpretative clarification. In contrast, the anonymous Old English verse translation composed during the tenth century approaches the psalms in a spirit of prayer and devotion. Despite their differences, both reflect earnest attempts to capture the literal meaning of the psalms. The complete text of all 150 prose and verse psalms is available here in contemporary English for the first time. With this translation readers encounter the beginnings and the continuation of a long tradition of psalm renderings in English.
