Incorporating technological change in diffusion models
The theoretical and empirical implications of a static and dynamic logistic diffusion model are compared. The dynamic model relaxes some assumptions of the static model by allowing for a flexible adoption ceiling, for changes in the technology, and for disadoption. Both models were used to estimate the diffusion of semi-dwarf wheat varieties in the United States. The dynamic model provides a better fit to the data and provides additional insights into the economic determinants of adoption. In particular, the importance of technological change in other areas (here, in fertilizer) on the diffusion path of an innovation was shown.

A Field Guide for Science Writers
This is the official guide for the National Association of Science Writers. In the eight years since the publication of the first edition of A Field Guide for Science Writing, much about the world has changed. Many of the leading issues in today's political marketplace--embryonic stem cell research, global warming, health care reform, space exploration, genetic privacy, germ warfare--are informed by scientific ideas. Never has it been more crucial for the lay public to be scientifically literate. That's where science writers come in. And that's why its time for an update to the Field Guide, already a staple of science writing graduate programs across the country.

Public Regulation of Agricultural Biotechnology Field Tests: Economic Implications of Alternative Approaches
Federal oversight of agricultural biotechnology field testing is based on public concerns that unknown consequences could arise from such tests, and that firms may not adequately consider the public consequences of their research and development activities. In this paper, four general types of ex ante and ex post approaches to manage public risks from field testing are explored. The analysis shows that the approaches are least effective at facilitating the research process yet controlling public risks when the research firm is small in size and potential damages exceed the value of the firm.

Whose price wins: Institutional and technical change in agriculture
The concern for environmental quality has become an increasingly dominant force for institutional and technical change in agriculture. The current conflict over water use between the farm sector and environmental groups is used to analyze the dynamic and recursive process of institutional and technical change in agriculture. Two general processes are analyzed by which conflicts are resolved. One leads to Pareto-efficient and the other leads to Pareto-noncomparable resolution of conflict. It is concluded that Pareto-efficient conflict resolution, represented by bargaining within the existing institutional structure, will continue to play a minor role in reducing environmental problems in agriculture. Consequently, Pareto-noncomparable conflict resolution, whereby the rules are changed to improve one's negotiating position, will remain the norm for addressing environmental problems in agriculture.

Radically New Designs for `Safe' ReactorsThis year is crucial for the future of nuclear energy. Willgovernment and the utilities invest in it?
If a new-generation nuclear plant could be developed that would be more acceptable to the public for safety reasons and also be more economical for utilities to build, it could result in construction of hundreds of nuclear power plants in the United States by the turn of the century, said Vince Boyer, senior vice president at Philadelphia Electric Co. and an officer of the gas-cooled reactor group. An indication of the Energy Department's support for the liquid metal reactor is that the development budget proposed for next fiscal year includes $41.4 million for the liquid metal reactor and only $5 million for the gas-cooled reactor. The proposed new-generation designs have won support from an unusual source: the Union of Concerned Scientists, a group of about 100,000 members, mostly university-based scientists, who have taken stands against existing nuclear plants they believe to be unsafe, sought an end to development of a nuclear breeder reactor and oppose the proliferation of nuclear power for defense.
