AN ANALYSIS OF FACTORS AFFECTING CONSUMERS' DECISIONS TO SHOP AT STORES OFFERING SPECIALTY MEAT

The empirical results suggest that the likelihood of grocery shoppers buying at stores that offer specialty meat is influenced by age, household size, education, ethnicity, and prices but is invariant to geographical location, gender, marital status, religion, occupation, and household income. From these results, a niche market for specialty meat is more likely among grocery shoppers aged 42 or younger, those from households with three persons or less, those without a high school diploma, or non-Caucasians. Price plays an important role in grocery shoppers' decisions to buy at stores offering specialty meat.Consumer/Household Economics,

AN ANALYSIS OF NUTRITIONAL LABEL USE IN THE SOUTHERN UNITED STATES

Results from a random telephone survey of 1,421 grocery shoppers in the South suggest that 80 percent of them used food labels when making food purchasing decisions. Overall, shoppers used the information on fat content more frequently than any other labeling information. Label and attribute use were found to be statistically significantly associated with age, educational level, gender, household composition, household income, marital status, and race.Food Consumption/Nutrition/Food Safety,

A Multispectral Look at Oil Pollution Detection, Monitoring, and Law Enforcement

The problems of detecting oil films on water, mapping the areal extent of slicks, measuring the slick thickness, and identifying oil types are discussed. The signature properties of oil in the ultraviolet, visible, infrared, microwave, and radar regions are analyzed

Squeeze-film dampers for turbomachinery stabilization

A technique for investigating the stability and damping present in centrally preloaded radially symmetric multi-mass flexible rotor bearing systems is presented. In general, one needs to find the eigenvalues of the linearized perturbation equations, though zero frequency stability maps may be found by solving as many simultaneous non-linear equations as there are dampers; and in the case of a single damper, such maps may be found directly, regardless of the number of degrees of freedom. The technique is illustrated for a simple symmetric four degree of freedom flexible rotor with an unpressurized damper. This example shows that whereas zero frequency stability maps are likely to prove to be a simple way to delineate multiple solution possibilities, they do not provide full stability information. Further, particularly for low bearing parameters, the introduction of an unpressurized squeeze film damper may promote instability in an otherwise stable system

Intergenerational Use of and Attitudes Toward Food Labels in Louisiana

Results from a random sample of 1,300 households in Louisiana suggest that seniors are the most frequent users of food labels, but they are also more likely to agree that labels are hard to interpret. Consumers in the 18-to-25 age group are more likely to use friends, relatives, and food-company publications as their main sources of nutritional information.Food Consumption/Nutrition/Food Safety,

FACTOR DEMANDS OF LOUISIANA RICE PRODUCERS: AN ECONOMETRIC INVESTIGATION

A Diewert-flexible (dual) cost function was used to derive a system of conditional factor demand equations for Louisiana rice producers. Generalized Leontief cost and factor share equations were fitted for the 1955-87 period using Zellner's SURE system estimation procedure. The Aitken parameter estimates reveal that: (1) the optimal input mix of rice farmers varies with production scale, (2) the factor-augmenting technical change is labor and chemical saving but seed using, (3) pairwise input substitutions are limited, and (4) factor demands are own-price inelastic. An implication is that Louisiana rice farmers will not appreciably alter their factor utilizations when relative input prices change.Demand and Price Analysis,
