Farming Systems Research/Extension And The Concepts Of Sustainability, Charles A. Francis, Peter E. Hildebrand
Department of Agronomy and Horticulture: Faculty Publications
Farming Systems Research and Extension (FSR/E) has strongly influenced the direction of agricultural development over the past two decades. Involving farmers, change agents and researchers, this participatory approach to technological improvement has evolved as an efficient means to develop individual components and more integrated systems that are uniquely suited to specific biophysical and socioeconomic conditions. Farmers with similar conditions and for whom specific recommendations are appropriate are grouped, in FSR/E, into identifiable Recommendation Domains. The technologies recommended conform with the biophysical and socioeconomic constraints that create environments within the domains, based on the philosophy that new technologies must conform with …

Executive Summary
Biological diversity refers to the variety and variability among living organisms and the ecological complexes in which they occur. Diversity can be defined as the number of different items and their relative frequency. For biological diversity, these items are organized at many levels, ranging from complete ecosystems to the chemical structures that are the molecular basis of heredity. Thus, the term encompasses different ecosystems, species, genes, and their relative abundance (OTA, 1987).
There is an ongoing, unprecedented loss of the variety as well as absolute numbers of organisms-from the smallest microorganism to the largest and most spectacular of …
Synthesis And Antibacterial Studies Of Some 2-Furanthiocarboxyhydrazones, Xiaorong Li, Zoumin Sun, James C. Chang
Synthesis And Antibacterial Studies Of Some 2-Furanthiocarboxyhydrazones, Xiaorong Li, Zoumin Sun, James C. Chang
Journal of the Iowa Academy of Science: JIAS
Seven 2-furanthiocarboxyhydrazones were prepared, 5-nitro-furaldehyde-2-furanthiocarboxyhydrazone from the reaction of 2-furanthiocarboxyhydrazide with 5-nitro-2-furaldiacetate and the others from the condensation of 2-furanthiocarboxyhydrazide with aldehydes: 2- furaldehyde, benzaldehyde, p-hydroxybenzaldehyde, o-methoxybenzaldehyde, o-vanillin, and salicylaldehyde. The seven 2-furanthiocarboxyhydrazones were tested for their antibacterial activities against Staphyloccocus aureus and Bacillus subtilis. 5-Nitro-2-furaldehyde-2- furanthiocarboxyhydrazone was found to display the strongest bacterotoxicity.
Ecology Of Iowa Drosophila Ii. Lowland Forest And Sand Prairie, Neil J. Jennings, Robert D. Seager
Ecology Of Iowa Drosophila Ii. Lowland Forest And Sand Prairie, Neil J. Jennings, Robert D. Seager
Journal of the Iowa Academy of Science: JIAS
The seasonal abundances of Drosophila species collected from a lowland forest community and from a sand prairie community in northeastern Iowa are compared. With some important exceptions, the patterns seen in the lowland forest community were similar to what had been observed in a previous collection (Jennings et al. 1985). Fewer species and many fewer individuals were collected from the sand prairie community, although in general the patterns seen were similar to those of the lowland forest community. Strong evidence of microhabitat differentiation was seen in both communities. In contrast to our previous study, none of the seasonal abundance patterns …
The Vascular Flora Of Pilot Knob State Preserve, William C. Watson
The Vascular Flora Of Pilot Knob State Preserve, William C. Watson
Journal of the Iowa Academy of Science: JIAS
Pilot Knob State Preserve is a 365 acre (147 ha) area lying within the boundaries of Pilot Knob State Park. Located in north central Iowa near the northeast corner of Hancock County, this preserve resides on the eastern morainal system of the Des Moines Lobe left from the Wisconsinan glaciation. The vegetation of the preserve is primarily a deciduous woodland on rolling hills interspersed with wetland habitats in the hollows. Iowa's only floating bog is present in one of these hollows and supports numerous vascular plants uncommon to the state. Two species, Carex cephalantha (Bailey) Bickn. and Drosera rotundifolia L., …
Iowa Geology: The Early Years, Wayne I. Anderson
Iowa Geology: The Early Years, Wayne I. Anderson
Journal of the Iowa Academy of Science: JIAS
In 1975 on the occasion of the first one hundred years of the Iowa Academy of Science, Robert W. Hanson summarized the history of the organization. Additional historical accounts covering many of the science disciplines were published during the centennial year. Although geology was not treated separately in these special articles, the contributions of early geologists were important to the development of science in our state. Consequently, it is appropriate to consider the contributions of early geologists in Iowa in celebration of the one hundredth annual meeting of the Iowa Academy of Science. Included in the present report are the …

The Development Of A Personalized Computer Assisted School Psychology (Casp) System, Patricia Lou Steinert
Dissertations
The purpose of this project was to develop a model computer system to assist school psychologists in managing and manipulating data accumulated in the course of accomplishing their professional responsibilities. School psychologists have traditionally generated large amounts of data, but rarely have they looked across these data to obtain information and/or feedback about their own functioning relative to their professional role. The system described is intended as a model from which an individual psychologist might construct a system to meet individual needs. Data across students were accumulated in four broad areas: (1) personal effectiveness/accountability, (2) diagnosis, (3) local test norms, …

Economic Considerations For Artificial Reef Development In Coastal Virginia, Dean Thomas Devereaux
Economic Considerations For Artificial Reef Development In Coastal Virginia, Dean Thomas Devereaux
OES Theses and Dissertations
The contingent valuation method, recommended by the U. S. Water Resources Council, was used to estimate the economic value of sport fishing and diving at the Chesapeake Light Tower Artificial Reef. The study is based on a random sample of 170 anglers and 33 divers who participated in telephone, personell and mail-in surveys in 1985 and 1986.
The average user value (consumer surplus) was $21.13, $110,75, and $13.30 for head boat anglers, private boat anglers and sport divers, respectively, who claimed to have used the reef in 1985. Variation in consumer surplus was statistically affected by trip expense, distance from …

Indian reservations constitute about 2.5% of all land in the country and 5% of all land in the American West. During the last two decades, Indian natural resources issues have moved to the forefront as tribal governments have dramatically expanded their regulatory programs, judicial systems. and resource development activities. This major symposium will address current developments and assess likely future directions in the areas of tribal, federal, and state regulation; tribal-state intergovernmental agreements; financing; mineral …
