Testing Strategies for Model-Based Development - Mats P Heimdahl

Testing Strategies for Model-Based Development - Mats P Heimdahl

This report presents an approach for testing artifacts generated in a model-based development process. This approach divides the traditional testing process into two parts: requirements-based testing (validation testing) which determines whether the model implements the high-level requirements and model-based testing (conformance testing) which determines whether the code generated from a model is behaviorally equivalent to the model. The goals of the two processes differ significantly and this report..

Economics of Food Labeling

Economics of Food Labeling

Federal intervention in food labeling is often proposed with the aim of achieving a social goal such as improving human health and safety, mitigating environmental hazards, averting international trade disputes, or supporting domestic agricultural and food manufacturing industries. Economic theory suggests, however, that mandatory food-labeling requirements are best suited to alleviating problems of asymmetric information and are rarely effective in redressing environmental or other spillovers associated..

Imports from China and Food Safety Issues

Imports from China and Food Safety Issues

The U.S. Food and Drug Administration's (FDA) increased attention to food imports from China is an indicator of safety concerns as imported food becomes more common in the United States. U.S. food imports from China more than tripled in value between 2001 and 2008. Addressing safety risks associated with these imports is difficult because of the vast array of products from China, China's weak enforcement of food safety standards, its heavy use of agricultural chemicals, and its considerable environmental..

Local Food Systems - Concepts, Impacts, and Issues

Local Food Systems - Concepts, Impacts, and Issues

This comprehensive overview of local food systems explores alternative definitions of local food, estimates market size and reach, describes the characteristics of local consumers and producers, and examines early indications of the economic and health impacts of local food systems. There is no consensus on a definition of \local\ or \local food systems\ in terms of the geographic distance between production and consumption. But defining \local\ based on marketing arrangements, such as farmers..

Changing Structure of Global Food Consumption and Trade

Changing Structure of Global Food Consumption and Trade

Higher income, urbanization, other demographic shifts, improved transportation, and consumer perceptions regarding quality and safety are changing global food consumption patterns. Shifts in food consumption have led to increased trade and changes in the composition of world agricultural trade. Given different diets, food expenditure and food budget responses to income and price changes vary between developing and developed countries. In developing countries, higher income results in increased demand..

Food Insecurity in Households with Children - Prevalence, Severity, and Household Characteristics

Food Insecurity in Households with Children - Prevalence, Severity, and Household Characteristics

Eighty-four percent of U.S. households with children were food secure throughout 2007, meaning that they had consistent access to adequate food for active, healthy lives for all household members. Nearly 16 percent of households with children were food insecure sometime during the year, including 8.3 percent in which children were food insecure and 0.8 percent in which one or more children experienced very low food security-the most severe food-insecure condition measured by the U.S. Department of..

Household Food Security in the United States in 2010

An estimated 85.5 percent of American households were food secure throughout the entire year in 2010, meaning that they had access at all times to enough food for an active, healthy life for all household members. The remaining households (14.5 percent) were food insecure at least some time during the year, including 5.4 percent with very low food security-meaning that the food intake of one or more household members was reduced and their eating patterns were disrupted at times during the year because..

Food Stamps and Obesity - What Do We Know?

Food Stamps and Obesity - What Do We Know?

Results from reviewed studies indicate that for most participants in the Food Stamp Program-children, nonelderly men, and the elderly-use of food stamp benefits does not result in an increase in either Body Mass Index (BMI) or the likelihood of being overweight or obese. However, for nonelderly women, who account for 28 percent of the food stamp caseload, some evidence suggests that participation in the Food Stamp Program may increase BMI and the probability of obesity. Different results for age..

Food Stamp Benefits and Childhood Poverty in the 1990s

Food Stamp Benefits and Childhood Poverty in the 1990s

In 2000, 8.8 million children received food stamps, making the Food Stamp Program a crucial component of the social safety net. Despite its importance, little research has examined the effect of food stamps on children's overall well-being. Using the Current Population Survey from 1989 to 2001, we consider the impact of food stamps on three measures of poverty-the headcount, the poverty gap, and the squared poverty gap. These measures portray the incidence, depth, and severity of poverty. We find..

Characteristics and Influential Factors of Food Deserts

Characteristics and Influential Factors of Food Deserts

USDA's Economic Research Service previously identified more than 6,500 food desert tracts in the United States based on 2000 Census and 2006 data on locations of supermarkets, supercenters, and large grocery stores. In this report, we examine the socioeconomic and demographic characteristics of these tracts to see how they differ from other census tracts and the extent to which these differences influence food desert status. Relative to all other census tracts, food desert tracts tend to have smaller..

Food Security Assessment - Why Countries Are at Risk

Food Security Assessment - Why Countries Are at Risk

Food insecurity in many low-income, developing countries is projected to intensify unless steps are taken to reverse the performance trend of key contributing factors: agricultural productivity, foreign exchange earnings, and population growth. For the poorest countries, an increase in agricultural productivity is the key to improving food security. In these countries, imports play a small role in the domestic food supply because of limited foreign exchange availability. This study evaluates availability..

Demand for Food Quantity and Quality in China

Demand for Food Quantity and Quality in China

As their incomes rise, Chinese consumers are changing their diets and demanding greater quality, convenience, and safety in food. Food expenditures grow faster than quantities purchased as income rises, suggesting that consumers with higher incomes purchase more expensive foods. The top-earning Chinese households appear to have reached a point where the income elasticity of demand for quantity of most foods is near zero. China's food market is becoming segmented. The demand for quality by high-income..
