News and information about genome research in forest trees for forest biologists and forest managers.
Concerns about the role and responsibilities of the media have become an increasingly important part of public debate. Media Ethics brings together philosophers, academics and media professionals to debate both ethics and morality.
In this book Clodovis Boff rigorously and passionately erects the methodological scaffolding that is necessary to construct a true theology of the political, a true theology of liberation. Much of the book is devoted to clarifying and articulating the boundaries of the relationships among theology, the political, the social sciences, hermeneutics, and praxis. As an element of that constructive work, Boff carefully points out the past and present theoretical shortcomings of political theology and the theology of liberation. Thus the book fills a methodological void that has hampered the full development of a theology of the political, and it blazes a path beyond what the author calls the "first phase" of liberation theology.
Most forest tree species were considered recalcitrant a decade ago, but now with the improved in vitro techniques some progress has been made towards culture-of tree species. Micro propagation has been achieved from the juvenile tissues of a number of forest tree species. On the other hand, tissues from most mature trees are still very difficult to grow and differen tiate in vitro. Nevertheless, there has been slow but steady progress in the application of tissue culture technology for culture of tissues, organs, cells and protoplasts of tree species. As compared to most agricultural crops, and herbaceous plant species, trees are a different lot. They have long gene ration cycles. They are highly heterozygous and have a large reservoir of genetic variability. Because of this genetic variability, their response in vitro is also variable. On a single medium, the response of tissues from different trees (genotypes) of a single species may be quite different: some responding by induction of growth and differentiation, while others showing minimal or no growth at all. That makes the somatic cell genetics of woody plants somewhat difficult, but at the same time interesting.
This volume is based on a workshop on Woody Plant Biotechnology held at the Institute of Forest Genetics, USDA Forest Service, Placerville, California, USA, 15-19 October, 1989. This workshop was organized by the IUFRO (International Union of Forestry Research Organizations) Working Party S2.04-07 - Somatic Cell Genetics -, and supported by the NATO Scientific Affairs Division, Advanced Research Workshop (ARW 692/89) Programme. This was the second workshop of the IUFRO Working Party on Somatic Cell Genetics. The first meeting of this Working Party was held at the Institute of Forest Genetics and Forest Tree Breeding, Federal Research Centre for Forestry and Forest Products, Grosshansdorf, Fe...
Who Owns the World's Media? moves beyond the rhetoric of free media and free markets to provide a dispassionate and data-driven analysis of global media ownership trends and their drivers. Based on an extensive data collection effort from scholars around the world, the book covers 13 media industries, including television, newspapers, book publishing, film, search engines, ISPs, wireless telecommunication and others, across a 10-25 year period in 30 countries.
Muhlmann is highly regarded as one of the outstanding young scholars of journalism and political communication. Polity recently published 'A Political History of Journalism' by the same author. This book is designed as a companion volume; it focuses on the relation of journalism to democracy.
