A Comparison of Predicted and Actual Trophic Status of Lake Ray Roberts, Texas Based on Chlorophyll A (open access)

A Comparison of Predicted and Actual Trophic Status of Lake Ray Roberts, Texas Based on Chlorophyll A

Two years before impoundment, the trophic status of Lake Ray Roberts was predicted by applying the total phosphorus input into the Organization for Economic Cooperation and Development (OECD) eutrophication model. Predicted mean summer epilimnetic (MSE) chlorophyll a of Elm Fork arm, Isle duBois arm and Main Body were in the eutrophic category of the OECD model. Observed MSE chlorophyll a two years after impoundment of Elm Fork arm, Isle duBois and Main Body had not reached their predicted means and were at the mesotrophic-eutrophic boundary of the OECD model. Six years after impoundment, observed MSE chlorophyll a for Main Body, was closer to its predicted mean and in the eutrophic category of the OECD model. Six years after impoundment, Elm Fork arm was the most productive area of Lake Ray Roberts. Observed means of chlorophyll a, total phosphates, suspended solids and turbidity were often highest in the Elm Fork arm. Wastewater effluent from Gainesville and Valley View, TX, had an impact on productivity in Elm Fork arm.

The Anglo-American Council on Productivity: 1948-1952 British Productivity and the Marshall Plan (open access)

The Anglo-American Council on Productivity: 1948-1952 British Productivity and the Marshall Plan

The United Kingdom's postwar economic recovery and the usefulness of Marshall Plan aid depended heavily on a rapid increase in exports by the country's manufacturing industries. American aid administrators, however, shocked to discover the British industry's inability to respond to the country's urgent need, insisted on aggressive action to improve productivity. In partial response, a joint venture, called the Anglo-American Council on Productivity (AACP), arranged for sixty-six teams involving nearly one thousand people to visit U.S. factories and bring back productivity improvement ideas. Analyses of team recommendations, and a brief review of the country's industrial history, offer compelling insights into the problems of relative industrial decline. This dissertation attempts to assess the reasons for British industry's inability to respond to the country's economic emergency or to maintain its competitive position faced with the challenge of newer industrializing countries.

The Electronic Ranch: the Information Environment of Cattle Breeders (open access)

The Electronic Ranch: the Information Environment of Cattle Breeders

The present study was a longitudinal analysis of the information needs of Red Angus cattle breeders and their use of networked information services. It was based on two surveys. The first, conducted in 1995--96, polled all 1067 ranches of the Red Angus Association of America. Responses from 192 Red Angus breeders were used to determine the value of different information types and to evaluate perceptions of the greatest barriers to the adoption of network information services. The second survey, mailed to 41 Red Angus breeders in 1998, focused on early adopters and likely users of network services. Responses from 15 breeders were used to evaluate perceptions of the greatest barriers to the effective use of Web-based information services.
