The chemistry of heterocyclic compounds now forms one of the most extensive and important branches of organic chemistry. The rapid expansion of investigation in this field is due largely to the ever increasing practical importance of heterocyclic com pounds. The present stage in the development of organic chemistry and closely allied branches of biology is characterized by extensive investigation of physiologically active substances encountered in the plant and animal world and playing important parts in the life processes of micro- and macro-organisms. This extensive inves tigation of alkaloids, vitamins, hormones, antibiotics and their synthetic substitutes, and also of substances that control the bio chemical processes of the nervous system, has acted as a powerful stimulus to the further development of the chemistry of hetero cyclic compounds. Moreover, there are many well known applications of heterocyclic compounds in the manufacture of dyes, synthetic resins, synthetic rubbers, and other important materials. In response to growing demands, several monographs and treatises on the chemistry of heterocyclic compounds have appeared in recent years, the most comprehensive of these being the series "Heterocyclic Compounds," edited by R. C. Elderfield, which is already appearing in Russian translation. On the other hand, the lack of a practical guide to the laboratory preparation of hetero cyclic compounds is being felt more and more.

This book provides a collection of applicable learning theories and their applications to science teaching. It presents a synthesis of historical theories while also providing practical implications for improvement of pedagogical practices aimed at advancing the field into the future. The theoretical viewpoints included in this volume span cognitive and social human development, address theories of learning, and describe approaches to teaching and curriculum development. The book presents and discusses humanistic, behaviourist, cognitivist, and constructivist theories. In addition, it looks at other theories, such as multiple intelligences theory, systems thinking, gender/sexuality theory and indigenous knowledge systems. Each chapter follows a reader-motivated approach anchored on a narrative genre. The book serves as a guide for those aiming to create optional learning experiences to prepare the next generation STEM workforce.

Ethnic Relations in the USSR (1986) focuses on popular ethnic attitudes and behaviour among the various nations and nationalities of the Soviet Union. Ethnicity matters not only in Soviet high politics and in economic and cultural planning, but is also a dominant force in the daily lives of many Soviet citizens. Using a combination of political and sociological methods, the author draws out the patterns and determinants of ethnic relations among the major nationalities at both the group and individual levels. Co-winner of the 1987 American Political Science Association Ralph E. Bunche Award

This book examines the origins and execution of Russian military and political activities in Moldova, Georgia, Ukraine, and Azerbaijan. Using a realist perspective, the author concludes that there are substantial similarities in the four case studies: Russian support for minority separatist movements, conflict, Russian intervention as peacekeepers, Russian control over the diplomatic process to prevent resolution of the conflict, and a perpetuation of Russian presence in the area. The author places the conflicts in the context of international law and nationalism theory.

Politics, work, and daily life in the USSR is designed to illustrate how the Soviet social system really works and how the Soviet people cope with it. This study is based on the first comprehensive survey of life in the USSR since the Harvard Project over thiry-three years ago. The essays contained analyze the variations in attitude and behaviour reflected in the findings of the Soviet Interview Project, a five-year investigation of contemporary daily life in the USSR. The survey involved interviewing thousands of recent emigrants from the USSR to the United States as a means of learning about their former day-to-day lives. Some aspects of this survey dealt with areas the Soviets themselves had never investigated, so the data were not, and indeed still are not, available even in unpublished Soviet sources. This study of a large volume of firsthand observations is extremely valuable to anyone interested in the inner workings and behavioural dynamics of the contemporary Soviet social system.

Hundreds of thousands of works of art and artefacts from many parts of the Pacific are dispersed across European museums. They range from seemingly quotidian things such as fish-hooks and baskets to great sculptures of divinities, architectural forms and canoes. These collections constitute a remarkable resource for understanding history and society across Oceania, cross-cultural encounters since the voyages of Captain Cook, and the colonial transformations that have taken place since. They are also collections of profound importance for Islanders today, who have varied responses to their disp.
