OBJECTIVE The present study examined the association between area socio-economic status (SES) and food purchasing behaviour. DESIGN Data were collected by mail survey (64.2 % response rate). Area SES was indicated by the proportion of households in each area earning less than $AUS 400 per week, and individual-level socio-economic position was measured using education, occupation and household...

Standard approaches to measuring the welfare gains from variety take variety as exogenous to consumers. Empirically we observe an Engel curve for variety, with richer consumers purchasing a larger set of varieties than poor ones. I present a tractable model for analyzing the welfare gains from variety in the presence of this non-homotheticity. The model generates variety Engel curves through di...

Research was conducted to determine the food habits of Hawaiian Crow (Corvus hawaiiensis) nestlings, variety of food items ingested relative to their age, and the nutritional composition of ingested fruits. Knowledge of the fruits’ nutritive value and the nestlings’ diet allowed us to determine what plants best meet nutritional needs of adult and nestling crows for restocking purposes. Our eval...

The Centers for Disease Control and Prevention estimated 23,000,000 cases of viral gastroenteritis caused by Norovirus in 2000, 40% of which were transmitted by food including: a variety of fresh produce, cake, deli meats, fruit salad, cheeses and ice. (CDC, 2003). An estimated 83,391 cases of Hepatitis A virus was reported in 2000, of which 5% was attributed to foodborne transmission (CDC, 200...

Background: In this study, the toxicity of the different xenobiotics was tested on the fruit fly Drosophila melanogaster model system.  Methods: Fly larvae were raised on food supplemented with xenobioticsat different concentrations (sodium nitroprusside (0.1-1.5 mM), S-nitrosoglutathione (0.5-4 mM), and potassium ferrocyanide (1 mM)). Emergence of flies, food intake by larvae, and pupation h...

Wheat is one of the important food staff in consumption pattern of each country. More than 50 % of human energy is supplied from bread in the developing country. Combine losses is less than 2-3% in developed countries, while in developing country is about 15-20% in different regions and circumstances of harvesting seasons and field conditions. In this research project that effect of combine typ...
