With more than 10,000 species that vary in size, use diverse habitats that extend across latitudes and altitudes, consume a wide variety of food items, differ in how they fly (or not), communicate, and reproduce, and have different life histories, birds exhibit remarkable variation in form (anatomy) and function (physiology). Our understanding of how natural selection has generated this variation as birds evolved and as different species adapted to their unique circumstances has grown considerably in recent years. In In a Class of Their Own: A Detailed Examination of Avian Forms and Functions, this variation is explained in great detail, beginning with an overview of avian evolution and continuing with information about the structure and function of the avian skeleton, muscles, and the various body systems. Other chapters focus on avian locomotion (including flight), migration, navigation, communication, energy balance and thermoregulation, and various aspects of avian reproduction, such as nests and nest building, clutch sizes, and parental care. In a Class of Their Own: A Detailed Examination of Avian Forms and Functions will be must reading for anyone, professional or non-professional, who needs or wants to learn more about birds.
This book examines the links between economic growth, changing employment conditions, and the reduction of poverty in Latin America in the 2000s. Our analysis answers the following broad questions: Has economic growth resulted in gains in standards of living and reductions in poverty via improved labour market conditions in Latin America in the 2000s, and have these improvements halted or been reversed since the international crisis of 2008? How do the rate and character of economic growth, changes in the various employment and earnings indicators, and changes in poverty and inequality indicators relate to each other? Our contribution is an in-depth study of the multi-pronged growth-employment-poverty nexus based on a large number of labour market indicators (twelve employment and earnings indicators and four poverty and inequality indicators) for a large number of Latin American countries (sixteen of them). The book presents a positive and hopeful set of findings for the period 2000 to 2012/13. Economic growth took place and brought about improvements in almost all labour market indicators and consequent reductions in poverty rates. But not all improvements were equal in size or caused by the same things. Some macroeconomic factors were associated with changes in labour market conditions, some of them always in the welfare-improving direction and some others always in the welfare-reducing direction. Most countries in the region suffered a deterioration in at least some labour market indicators as a consequence of the international crisis of 2008, but the negative effects were reversed very quickly in most countries.
Building on the foundation of a one-year introductory course in organic chemistry, Bioorganic Synthesis: An Introduction focuses on organic reactions involved in the biosynthesis of naturally-occurring organic compounds with special emphasis on natural products of pharmacological interest. The book is designed specifically for undergraduate students, rather than as an exhaustive reference work for graduate students or professional researchers and is intended to support undergraduate courses for students majoring in chemistry, biochemistry, biology, pre-medicine, and bioengineering programs who would benefit from a deeper understanding of the chemical logic of reactions carried out in organisms and the origins and uses of the important organic compounds they often produce. The book assumes no prior background in biochemistry and consists of eight chapters: i) a brief review of relevant topics from introductory organic chemistry; ii) presentation of essential organic and biochemical reactions used throughout the book along with a brief introduction to coenzymes; iii) review of basic carbohydrates and the biosynthesis of amino acids; iv) the terpenoid pathway for biosynthesis of all important classes of terpenoids and steroids; v) the acetate pathway for biosynthesis of saturated and unsaturated fatty acids, prostaglandins and acetate-derived polyketide natural products; vi) the biosynthesis of the shikimate pathway products derived from aromatic amino acids; vii) an introduction to biosynthesis of major alkaloids and related nitrogenous compounds; and viii) an overview of laboratory organic synthesis as it relates to the challenges faced by synthetic and medicinal chemists who must recreate intricate natural product structures in the laboratory.
Robert Ariss, an HIV seropositive individual for many years, died from AIDS in 1994. This anthropological study documents his vision of the gay and lesbian community in Sydney and its members infected with and affected by HIV.
Before the interstates, Main Street America was the small town’s commercial spine and served as the linchpin for community social solidarity. Yet, during the past three decades, a series of economic downturns has left many of the great small cities barely viable. American Hometown Renewal is the first book to combine administrative, budgetary, and economic analysis to examine the economic and fiscal plight currently facing America’s small towns. Featuring a blend of theory, applications, and case studies, it provides a comprehensive, single-source textbook covering the key issues facing small town officials in today’s uncertain economy. Written by a former public manager, university professor, and consultant to numerous small towns in the Heartland, this book demonstrates the ways in which contemporary small towns throughout the nation are facing economic challenges brought about by the financial shocks that began in 2008. Each chapter explores a theme related to small town revival and provides a related tool or technique to enable small town officials to meet the challenges of the 21st Century. Encouraging local small town officials to look at the economic orbit of communities in a similar manner as a town’s budget or a family’s personal wealth, examining its specific competitive advantages in terms of relative assets to those of competing communities, this book provides the reader with step-by-step instructions on how to conduct an asset inventory and apply key asset tools to devise a strategy for overcoming the challenges and constraints imposed upon spatially-fixed communities. American Hometown Renewal is an essential primer for students studying city management, economic community development, and city planning, and will be a trusted handbook for city managers, geographers, city planners, urban or rural sociologists, political scientists, and regional microeconomists.
