Nature employs a wide variety of sex determining mechanisms and it is only comparatively recently that the tools have become available for these to be explored at the cellular and molecular levels. A major landmark was the discovery in 1990 of the SRY gene and the subsequent demonstration of its key role in triggering male sex determination in transgenic mice. This book reviews and discusses our current understanding of the molecular genetic pathways of sex determination, with special emphasis on vertebrates. It features comparisons with other modes of sex determination, consideration of the biology of sexual development and discussion of the evolution of sex-determining mechanisms.By bringing together an international and interdisciplinary group of experts who study many different aspects of the problem, the book highlights much new and exciting work in this area and serves to identify and stimulate promising new research directions.
The politics of the internet has entered the social science mainstream. From debates about its impact on parties and election campaigns following momentous presidential contests in the United States, to concerns over international security, privacy and surveillance in the post-9/11, post-7/7 environment; from the rise of blogging as a threat to the traditional model of journalism, to controversies at the international level over how and if the internet should be governed by an entity such as the United Nations; from the new repertoires of collective action open to citizens, to the massive programs of public management reform taking place in the name of e-government, internet politics and pol...
Providing an overview of Internet politics, this work examines the impact of communication technologies on political parties and elections, pressure groups, social movements, public bureaucracies, and global governance.
This book provides new teachers with concepts and pedagogical strategies designed to enhance the unique and individual characteristics of an increasingly diverse student population.
""A good story, well told, of a sliver of life in Richmond, a small, elite-driven capital city in the young nation's most influential state."" Publishers Weekly George Wythe clung to the mahogany banister as he inched down the staircase of his comfortable Richmond, Virginia, home. Doubled over in agony, he stumbled to the kitchen in search of help. There he found his maid, Lydia Broadnax, and his young protege, Michael Brown, who were also writhing in distress. Hours later, when help arrived, Wythe was quick to tell anyone who would listen, ""I am murdered."" Over the next two weeks, as Wythe suffered a long and painful death, insults would be added to his mortal injury. I Am Murdered tells ...
This national policy statement (NPS) sets out national policy for the energy infrastructure. A further five technology-specific NPSs for the energy sector cover: fossil fuel electricity generation (EN-2) (ISBN 9780108510786); renewable electricity generation (both onshore and offshore) (EN-3) (ISBN 9780108510793); gas supply infrastructure and gas and oil pipelines (EN-4) (ISBN 9780108510809); the electricity transmission and distribution network (EN-5) (ISBN 9780108510816); and nuclear power generation (EN-6) (ISBN 9780108510823). An Impact assessment is also available (ISBN 9780108510830). The NPSs have effect on the decisions by the Infrastructure Planning Commission on application for energy developments. This statement outlines the Government's objectives for the power sector in order to meet its energy and climate change strategy. It sets out the need for new energy infrastructure and the assessment principles and generic impacts.
Eleven sketches, "exhibits" in the Colored Museum, offer a humorous and irreverent look at slavery, Black cuisine, soldiers, family life, performers, and parties.
Meteorology of tropical West Africa: the Forecasters’ Handbook presents the science and practice of weather forecasting for an important region of the tropics. Connecting basic theory with forecasting practice, the book provides a unique training volume for operational weather forecasters, and is also suitable for students of tropical meteorology. The West African region contains a number of archetypal climatic zones, meaning that the science of its weather and climate applies to many other tropical regions. West Africa also exhibits some of the world’s most remarkable weather systems, making it an inspiring region for students to investigate. The weather of West Africa affects human livelihoods on a daily basis, and can contribute to hardship, poverty and mortality. Therefore, the ability to understand and predict the weather has the potential to deliver significant benefits to both society and economies. The book includes comprehensive background material alongside documentation of weather forecasting methods. Many examples taken from observations of West African weather systems are included and online case-studies are referenced widely.
A textbook covering the entire field, blending classical topics with the results of new research, summarizing yet presenting conflicting evidence and opinions, avoiding jargon when possible, and focusing on being a textbook rather than an exhaustive reference. First published in 1979 and again in 1987; here two new authors have been added to account for the broadening of the discipline. Some basic background in the biological sciences is assumed.
