An Empirical Analysis of Internet Use by U.S. Farmers AgEcon
Mishra, Ashok K.; Park, Timothy A..
The Internet may reduce constraints on a farmer’s ability to receive and manage information, regardless of where the farm is located or when the information is used. Using a count data estimation procedure, this study attempts to examine the key farm, operator, regional, and household characteristics that influence the number of Internet applications used by farm households. Findings indicate that educational level of the farm operator, farm size, farm diversification, off-farm income, off-farm investments, and regional location of the farm have a significant impact on the number of Internet applications used.

FARM COMPUTER ADOPTION IN THE GREAT PLAINS AgEcon
Hoag, Dana L.; Ascough, James C.; Frasier, W. Marshall.
Computers change rapidly, yet the last survey on computer use in agriculture was in 1991. We surveyed Great Plains producers in 1995 and used logit analysis to characterize adopters and non-adopters. About 37% of these producers use computers which is consistent with the general population. We confirmed previous surveys emphasizing the importance of education, age/experience, and other farm characteristics on adoption. However, we also found that education and experience may no longer be a significant influence. Future research and education could focus on when and where computers are most needed, and therefore when adoption is most appropriate.

Logiciels pour l'analyse et la conception de structures marines en composites: Problemes et perspectives ArchiMer
Papazoglou, V.
The rational procedure for the structural design of composite marine structures, including the determination of structural loading, material characterization, design criteria and performance of strength calculations, is first presented. This is followed by a critical analysis of the problems, limitations and future perspectives of the numerical tools necessary for the performance of analytical and design oriented calculations of composite marine structures.

Personal computer brand loyalty AgEcon
Jackson, Tyrone W.; Perloff, Jeffrey M..
A Markov model shows the degree of brand loyalty to Apple, Compaq, IBM, and Wyse personal computers by large corporate customers of Businessland, a large reseller of personal computers in the late 1980s and early 1990s. Because Businessland temporarily lost its franchise to carry Compaq for half a year in the middle of our sample, the model captures the effect on Businessland's sales of rival brands when a name brand is eliminated and then reintroduced. Large corporate customers were brand-loyal and relatively price insensitive. Their loyalty did not diminish over time. They did not view IBM-compatible computers as perfect substitutes. Eliminating and then reintroducing a brand has different short- and long-run effects. It is difficult to explain which...

TECHNOLOGICAL ADVANCES IN AGRICULTURAL ECONOMICS CURRICULA AgEcon
Schurle, Bryan W.; Comer, Dorothy A..
The potential use of computers and electronic technology have created considerable interest among educators in agricultural economics. This paper provides an overview of the use of electronic technology within agricultural economics curricula; examines areas in which technological development offers promise and examines issues associated with adoption of the technology.

The Determinants of the Global Digital Divide: A Cross-Country Analysis of Computer and Internet Penetration AgEcon
Chinn, Menzie D.; Fairlie, Robert W..
To identify the determinants of cross-country disparities in personal computer and Internet penetration, we examine a panel of 161 countries over the 1999-2001 period. Our candidate variables include economic variables (income per capita, years of schooling, illiteracy, trade openness), demographic variables (youth and aged dependency ratios, urbanization rate), infrastructure indicators (telephone density, electricity consumption), telecommunications pricing measures, and regulatory quality. With the exception of trade openness and the telecom pricing measures, these variables enter in as statistically significant in most specifications for computer use. A similar pattern holds true for Internet use, except that telephone density and aged dependency...
