The relationship between infoonation technology and business performance has been a focus of IS research in rccent years. However. few soUd results have been found as of yet which empirieally link them together. Sorne problems rcmain with the definition and measurement of rr. organizational perfonnance and "fit" between technology and ocganizational strategy. Thus stronger empirical evidence is...

OBJECTIVE To quantify the role of dietary Fe in total body Fe (TBI) accumulation among homozygotes for the HFE gene associated with haemochromatosis. DESIGN A Monte Carlo model was built to simulate Fe accumulation based on findings from human feeding experiments and national dietary surveys. A hypothetical cohort of 1000 homozygotes with starting age 25 years was used in 39-year simulations....

BACKGROUND AND OBJECTIVES To study the associations between nutrient intake, dairy intake and socioeconomic variables. METHODS AND STUDY DESIGN Food consumption data using 24 h recall were collected in 3600 children, aged 0.5 to 12 years old in addition to frequency of dairy use and anthropometric and sociodemographic variables. RESULTS Overall height for age Z-score (HAZ) and body mass ind...

The nutritional value of a high-carbohydrate diet was evaluated. Seven male marathon runners kept a food record diary for the three days preceeding two endurance races. They were instructed in how to compose a diet which contained about 9 g carbohydrate day-1 kg body weight-1. Sixty three per cent of the subjects' total energy intake was derived from carbohydrates. The dietary intake of vitamin...

Determinants of the recommended dietary allowance (RDA) for vitamin C include the relationship between vitamin C dose and steady-state plasma concentration, bioavailability, urinary excretion, cell concentration, and potential adverse effects. Because current data are inadequate, an in-hospital depletion-repletion study was conducted. Seven healthy volunteers were hospitalized for 4-6 months an...

Since the establishment of the 1998 folate recommended dietary allowance (RDA), the methylenetetrahydrofolate reductase (MTHFR) 677C-->T variant has emerged as a strong modifier of folate status. This controlled feeding study investigated the adequacy of the RDA, 400 microg/d as dietary folate equivalents (DFE), for Mexican American men with the MTHFR 677CC or TT genotype. Because of the interd...

The purposes of this study were to collect information regarding the dietary habits of male and female age-group swimmers and report the energy consumptions of these athletes in relation to their daily training demands. Twenty competitive swimmers, who were training 6000 m per day 6 days a week, recorded all fluid and food consumed during a 4-day period. Dietary analysis revealed that 11 swimme...
