Gilbert S. Omenn Dean, Public Health and Community Medicine University of Washington Seattle, Washington 98195 On behalf of the University of Washington, the City of Seattle, the sponsors and donors, and my co-organizers, I am delighted to welcome all of you to this Conference on Genetic Control of Environ mental Pollutants. My only regret is that Dr. Alexander Hollaender, who has inspired so many of us as young scientists and stimulated so many trail-blazing conferences in environmental sciences and in gen etic engineering, is ill and was unable to make the trip to Seattle. He sends his warm good wishes for an outstanding meeting and a fine volume. The purpose of this Conference is to identify and assess strat egies for more effectively and safely managing wastes and toxic sub stances in the environment, in part through use of genetically engi neered microorganisms. There is a sense of desperation in our soci ety that modern technologies have introduced a bewildering array of potential hazards to human health and to our environment. There is an accompanying sense of frustration that our prodigious basic re search capabilities and our technological ingenuity have not yielded practical ways to control many pollutants and waste streams, or- better still--to convert them to useful products.
This symposium is the third in a series featuring the propaga tion of higher plants through tissue culture. The first of these symposia, entitled "A Bridge Between Research and Application," was held at the University in 1978 and was published by the Technical Information Center, Department of Energy. The second symposium, on "Emerging Technologies and Strategies," was held in 1980 and pub lished as a special issue of Environmental and Experimental Botany. One of the aims of these symposia was to examine the current state of-the-art in tissue culture technology and to relate this state of technology to practical, applied, and commercial interests. Thus, the third of this series on development and variation focused on embryogenesis in culture: how to recognize it, factors which affect embryogenesis, use of embryogenic systems, etc.; and variability from culture. A special session on woody species again emphasized somatic embryogenesis as a means of rapid propagation. This volume emphasizes tissue culture of forest trees. All of these areas, we feel, are breakthrough areas in which significant progress is expected in the next few years.
William C. Taylor Department of Genetics University of California Berkeley, California 94720 It is evident by now that there is a great deal of interest in exploiting the new technologies to genetically engineer new forms of plants. A purpose of this meeting is to assess the possibilities. The papers that follow are concerned with the analysis of single genes or small gene families. We will read about genes found within the nucleus, plastids, and bacteria which are responsible for agri culturally important traits. Given that these genes can be isolated by recombinant DNA techniques, there are two possible strategies for plant engineering. One involves isolating a gene from a cultivated plant, changing it in a specific way and then inserting it back into the same plant where it produces an altered gene product. An example might be changing the amino acid composition of a seed pro tein so as to make the seed a more efficient food source. A second strategy is to isolate a gene from one species and transfer it to another species where it produces a desirable feature. An example might be the transfer of a gene which encodes a more efficient pho tosynthetic enzyme from a wild relative into a cultivated species. There are three technical hurdles which must be overcome for either strategy to work. The gene of interest must be physically isolated.
This book examines the development of drawing and painting from several currently dominant theoretical perspectives and examines empirical data on the art work of children who are ordinary, talented, emotionally disturbed, and atypically developed due to
This third edition of this best-selling book confirms the ongoing centrality of feminist perspectives and research to the sociological enterprise, and introduces students to the wide range of feminist contributions in key areas of sociological concern. Completely revised, this edition includes: new chapters on sexuality and the media additional material on race and ethnicity, disability and the body many new international and comparative examples the influence of theories of globalization and post-colonial studies. In addition, the theoretical elements have also been fully rethought in light of recent developments in social theory. Written by three experienced teachers and examiners, this book gives students of sociology and women's studies an accessible overview of the feminist contribution to all the key areas of sociological concern.
This book offers a unique insight into the key legal and social issues at play in New Zealand today. Tackling the most pressing issues, it tracks the evolution of these societal problems from 1840 to the present day. Issues explored include: illegal drugs; racism; the position of women; the position of Maori and free speech and censorship. Through these issues, the authors track New Zealand's evolution to one of the most famously liberal and tolerant societies in the world.
There has been a resurgence of community gardening over the past decade with a wide range of actors seeking to get involved, from health agencies aiming to increase fruit and vegetable consumption to radical social movements searching for symbols of non-capitalist ways of relating and occupying space. Community gardens have become a focal point for local activism in which people are working to contribute to food security, question the erosion of public space, conserve and improve urban environments, develop technologies of sustainable food production, foster community engagement and create neighbourhood solidarity. Drawing on in-depth case studies and social movement theory, Claire Nettle provides a new empirical and theoretical understanding of community gardening as a site of collective social action. This provides not only a more nuanced and complete understanding of community gardening, but also highlights its potential challenges to notions of activism, community, democracy and culture.
Characteristics of Hawaiian Volcanoes establishes a benchmark for the currrent understanding of volcanism in Hawaii, and the articles herein build upon the elegant and pioneering work of Dutton, Jagger, Steams, and many other USGS and academic scientists. Each chapter synthesizes the lessons learned about a specific aspect of volcanism in Hawaii, based largely o continuous observation of eruptive activity and on systematic research into volcanic and earthquake processes during HVO's first 100 years.

Adolescence is often thought of as a period during which parent–child interactions can be relatively stressed and conflictual. There are individual differences in this regard, however, with only a modest percent of youth experiencing extremely conflictual relationships with their parents. Relatively little empirical research, however, addresses individual differences in the quality of parent–adolescent interactions concerning potentially conflictual issues. The research reported in this monograph examined dispositional and parenting predictors of the quality of parents’ and their adolescent children’s emotional displays and positive and negative verbalizations when dealing with conflictual issues. Of particular interest were patterns of continuity and discontinuity in the factors related to conflicts. A multimethod, multireporter (mother, teacher, and sometimes adolescent reports) longitudinal approach(over 4 years) was used to assess adolescents’ dispositional characteristics (control/regulation, resiliency, and negative emotionality), youths’ externalizing problems, and parenting variables (warmth, positive expressivity, discussion of emotion, positive and negative family expressivity). Parentadolescent conflicts appear to be influenced by both child characteristics and quality of prior and concurrent parenting, and child effects may be more evident than parent effects in this pattern of relations.
