Associations between coping responses, drinking motivations, expectations of meeting social and academic goals, and family of origin problem drinking and measures of college students' quantity/frequency of alcohol use and social complications of alcohol use were investigated in a sample of 218 college students. Positive associations were found between(More)
Relationships among three motivational variables (negative-personal functions of drinking, alienation, and perceived discrepancies between valued goals and expected success toward valued goals) were evaluated in a group of 257 college drinkers. As predicted, a positive relationship between alienation scores and the extent of discrepancies between values and(More)
Cereal leaf beetle, Oulema melanopus (L.), has become a serious pest of small grains in the mid-Atlantic region of the United States. Existing thresholds for implementing control measures allowed too much leaf damage and consequent yield loss to occur before recommending treatment. Information on beetle biology and crop response to injury, both(More)
Caffeine consumption, a ubiquitous cultural phenomenon with significant health implications may be governed by some of the same principles which affect other drug use [1]. We hypothesized that pharmacological and expectancy effects may be two of those principles. A balanced placebo design was used with 100 male undergraduates to separate caffeine's active(More)
Direct and mediating effects of mechanisms hypothesized to account for the association between parental problem drinking and later problem drinking by offspring were investigated. Specifically, a "negative affect" submodel was proposed in which family environment, self-esteem, alienation, likelihood of attaining valued goals, psychopathology, and drinking(More)
In summer 2000, adult female bollworm moths, Helicoverpa zea (Boddie), were collected from light-traps at four locations near the Tidewater Research Station, Plymouth, NC. Female moths were allowed to lay eggs, and at hatch, 72 larvae from each female were screened for growth rate on normal artificial diet and on diets containing 5.0 microg of either Cry1Ac(More)
Two drinking motives scales, Negative Personal (NP) motives and Positive Social (PS) motives, derived from Mulford and Miller's Definitions of Alcohol Scales, and a Negative Family Models (NFM) scales designed to reflect family modeling of drinking-related problems were evaluated for internal consistency and association with college students' scores on a(More)
Transgenic cotton, Gossypium hirsutum (L.), expressing either one or two Bacillus thuringiensis ssp. kurstaki Berliner (Bt) proteins was compared with the conventional sister line in field experiments with regard to production of bollworm, Helicoverpa zea (Boddie), and bolls damaged by bollworm. The relative numbers of bollworms that developed on Bollgard(More)
Population changes of Heterodera glycines eggs on soybean in small field plots were influenced by the lepidopterous insect pest, Helicoverpa zea; however, few effects on eggs due to the presence of annual weeds were detected. Soybeans defoliated 15-35% by H. zea during August remained green and continued to produce new flowers and pods later into the season(More)
One susceptible and three Cry1Ac-resistant strains of tobacco budworm, Heliothis virescens (F.) (Lepidoptera: Noctuidae), were used in laboratory studies to determine the level of cross-resistance between the Bacillus thuringiensis (Berliner) toxins Cry1Ac and Vip3A by using concentration-mortality and leaf tissue experiments. Concentration-mortality data(More)
