Fishes are by far the most species-rich vertebrate taxon, and it is also the vertebrate group with the most strikingly diverse repertoire of behaviours and behavioural adaptations. As such, they provide us with many opportunities to explore the fascinating complexities of animal behaviour. Central questions addressed in this book include: How do sensory input, hormones, genetics and experience interact to shape individual behaviour? What should a fish do to be in the right place at the right time and how should it behave to be an efficient predator yet not become the subject of predation itself? How to find a mate or to find the best mate? Should all fish do the same, or is the optimal behaviour dependent on individual characteristics? How does reproductive behaviour affect what fish look like, in terms of colour, body form or body size? And how do fish cope with their complex social and biological environment, including parasites, competitors and collaborators? This new book provides an exciting overview of the many new insights offered by recent research on fish behaviour. The chapters are written by prominent international scientists and are aimed not only at fish biology students and researchers but anyone interested in the interplay between behaviour, ecology and evolution.

Global communication can be difficult in the best of circumstances. The contributors in this book take seriously the premise that one can examine communication within specific global settings and scenes with the goal of ensuring that the meanings made among those within specific communities is more clearly understood. This includes recognizing that we often communicate based on specific assumptions and act in ways that have normative bases that are shared with those within communities, but are often difficult to discern or navigate by those who are not members of them. Situated within the Ethnography of Communication research program, the contributors in this volume use Cultural Discourse Analysis to examine such practices, a theory and methodology developed by Donal Carbaugh over the past thirty years. The book is a celebration of his work and career, in which forty-four prominent Communication scholars and practitioners come together to use this framework to examine pressing communication issues across the globe. The book includes a preface by Gerry Philipsen that is an academic history of Carbaugh's career, an introduction outlining the history and current practice of Cultural Discourse Analysis, sixteen data based chapters using the framework to examine a broad range of inter/cultural communication practices across the globe, and an epilogue by Carbaugh reviewing this research and its future trajectory. The book is a handbook of Cultural Discourse Analysis for examining the latest in Cultural Discourse Analysis research and learning how to do such work that will be useful to advanced undergraduate and graduate students in a broad range of fields, inter/cultural communication scholars, and all those who seek to better understand and communicate in the global world today.

In recent years the techniques of chromatography have progressed rapidly. However, the aims and objectives of the First Edition, as quoted below, are just as relevant today as they undoubtedly were in 1963. 'The various methods of separating mixtures which are grouped under the general name chromatography are now well known and widely used. Since the inception of chromatography as a column technique in 1903, the principal landmarks in its progress have been its virtual rediscovery in the 1930s, the invention of synthetic resins in 1935, the introduction of paper chromatography in the early 1940s and finally, the development of gas solid and gas liquid chromatography in the late 1940s and early 1950s. Subsequent expansion in the use of chromatographic methods has been rapid and continuous, with the result that in the last 15 years a substantial volume of literature on the subject has appeared, dealing not only with particular separations but also in much specific detail with improvements in technique.

Since the inception of chromatography in 1903, the principal landmarks in its progress have been the virtual rediscovery of the technique in the 1930s, invention of synthetic resins in 1935, introduction of paper chromatography in the 1940s followed by that of thin layer, gas-solid and gas-liquid chroma- tography in the early 1950s. Whilst the theoretical aspects of HPLC were developed in the 1960s, it was the late 1970s before commercial instruments appeared. Developments through the 1980s in microelectronics and micro- processor technology afforded enhanced control, data acquisition and processing capabilities, and improved technologies for the manufacture of instrumentation. Developments in chromatographic media and packings and rapid scanning spectroscopic instruments have enabled combination techniques such as GC-MS, GC-IR, HPLC-MS and HPLC-IR to reach maturity and become standard routine techniques for the analyst. Further considerable research activity in the 1980s and early 1990s has led to the development of supercritical fluid chromatography (SFC), and high perfor- mance capillary electrophoresis is a technique that has proved invaluable in the genome project and the separation and typing of DNA fragments. Applications in environmental, health and safety, foods analysis and medical studies have contributed significantly to the advancement of these tech- niques. All of the instrumental chromatographic techniques are now used routinely by academic and industrial analysts. An understanding and experi- ence of such techniques is fundamental to the training of today's science undergraduates studying a range of disciplines reflecting the application areas mentioned above.

Until recently, histories of the American West gave little evidence of the presence--let alone importance--of African Americans in the unfolding of the western frontier. There might have been a mention of Estevan, slavery, or the Dred Scott decision, but the rich and varied experience of African Americans on the Great Plains went largely unnoted. This book, the first of its kind, supplies that critical missing chapter in American history. Originally published over the span of twenty-five years in "Great Plains Quarterly," the essays collected here describe the part African Americans played in the frontier army and as homesteaders, community builders, and activists. The authors address race relations, discrimination, and violence. They tell of the struggle for civil rights and against Jim Crow, and they examine African American cultural growth and contributions as well as economic and political aspects of black life on the Great Plains. From individuals such as "Pap" Singleton, Era Bell Thompson, Aaron Douglas, and Alphonso Trent; to incidents at Fort Hays, Brownsville, and Topeka; to defining moments in government, education, and the arts--this collection offers the first comprehensive overview of the black experience on the Plains.
