While the growth of business-to-consumer electronic commerce seems phenomenal in recent years, several studies suggest that a large number of individuals using the Internet have serious privacy concerns, and that winning public trust is the primary hurdle to continued growth in e-commerce. This research investigated the relative importance, when purchasing(More)
BACKGROUND Acute upper respiratory infections are common in children who attend child care, and preventing transmission of disease in this setting depends on actions by child care staff. We set out to discover whether transmission of respiratory infections in child care could be reduced by improved infection control procedures. METHODS We performed a(More)
An epithelial preparation of the bullfrog sacculus was used to characterize the initial rate of the adaptation mechanism in hair cells and its dependence on displacement and calcium. The I(X) curve relating transduction current and bundle displacement shifted along the X-axis without substantial change in slope, as previously observed, suggesting that(More)
This study investigated measures of sexual behavior displayed by female rats in bilevel chambers, the statistical relationships among the measures, and their dependency on hormone priming. Normative data from a standard 35-min test of sexual behavior were gathered from 82 fully primed sexually experienced Long-Evans females and subjected to multiple(More)
This research investigates the effects of technical (i.e. technical ability) and soft (i.e. emotional intelligence) skills on CS program retention. Structural equation modeling revealed that affinity (satisfaction with the major) was the most important factor in determining intention to leave the CS major. Unexpectedly, technical skills were the least(More)
Investigations into the possible causes of colitis and typhlocolitis were carried out on 85 pig units in the United Kingdom between 1992 and 1996. Serpulina pilosicoli was identified most commonly, occurring as the suggested primary agent on 21 (25 per cent) of the units but forming part of mixed infections on another 23 (27 per cent) of the units, the main(More)
OBJECTIVE To evaluate economic and clinical outcomes of a program of routine prenatal serotesting for varicella and postpartum vaccination of seronegative women. METHODS An analytic cost-effectiveness model was constructed to compare the current strategy of no serotesting with 1) selective serotesting of pregnant women without a prior history of(More)
BACKGROUND Diarrheal infections are common in children who attend child care, and preventing transmission of disease in this setting depends on actions by child care staff. We set out to discover whether transmission of gastrointestinal infections in child care could be reduced by improved infection control procedures. METHODS We performed a cluster(More)
Serum concentrations of insulin-like growth factor-I (IGF-I) and IGF-binding protein-1 (IGFBP-1), -2, and -3 are influenced by dietary intake in normal adults. These studies were undertaken to determine the influence of dietary factors on these proteins in children and to compare the responses in children to those in adults. Eight adults and eight pubertal(More)
