Estimating the demand for risk reduction from foodborne pathogens through food irradiation

In this study the response of US consumers to irradiation in meat processing is examined. Despite scientific evidence of the effectiveness and safety of irradiation, meat processors and retailers have been slow to market irradiated beef products due to uncertainty about consumer acceptance. The objective of this study was therefore to examine the factors influencing consumer demand for irradiation using data from a contingent valuation (CV) survey with 819 households in eight midwestern US states. The analysis focused on the value of reduced risk from Escherichia coli O157:H7 and Salmonella in ground beef consumption. Respondents were on average willing to pay a price premium of 22 cents/lb. for safer ground beef. Willingness to Pay (WTP) amounts were influenced by protective actions at home and varied partly with the scope of the risk reduction.food safety, irradiation, Willingness to Pay (WTP), Contingent Valuation (CV), Demand and Price Analysis, Food Consumption/Nutrition/Food Safety, Risk and Uncertainty,

Incidence of Behavior Problems in Toddlers and Preschool Children from Families Living in Poverty

Few studies have examined the incidence of behavior problems in toddlers and preschool children from families living in poverty. The available research suggests behavior problems occur at higher rates in children living in poverty and may have long-term negative outcomes if not identified and properly treated. This study included an ethnically representative sample of 357 children, five years of age and younger, from a diverse, low-income, urban area. All families’ incomes met the federal threshold for living in poverty. Behavior problems were assessed by parent report through a questionnaire specifically designed for low-income families. Boys and younger children were reported as demonstrating a higher rate of externalizing behaviors than girls and older children. The overall rate of children scoring at least one standard deviation above the sample\u27s mean for challenging behaviors was 17.4% and was not related to the child\u27s gender, age or ethnicity. This study also sampled children\u27s positive behaviors, which is unique in studies of behavior problems. Gender and age were not related to the frequency of reported positive behaviors. Ethnicity did influence scores on the positive scale. African American children appeared to present their parents more difficulty on items reflecting cooperative behaviors than Caucasian or Latino children. The implications of the study are discussed based on the recognized need for universal screening of behavior problems in young children and the small number professional training programs targeting the identification and treatment of early childhood behavior problems, despite the availability of evidence-based treatment programs tailored to young children in low-income families

CONSUMER DEMAND FOR MANDATORY LABELING OF BEEF FROM CATTLE ADMINISTERED GROWTH HORMONES OR FED GENETICALLY MODIFIED CORN

This study estimates the value of policies that would mandate labeling of beef from cattle produced with growth hormones or fed genetically modified corn. At no cost, 85 percent of resondents desired mandatory labeling of beef produced with growth hormones and 64 percent of respondents preferred mandatory labeling of beef fed genetically modified corn. Estimates suggest that consumers would be willing to pay 17.0 percent and 10.6 percent higher prices for beef on average to obtain information provided via mandatory labeling about whether the beef is from cattle produced with growth hormones or fed genetically modified corn, respectively.beef, contingent valuation, genetically modified foods, growth hormones, mandatory labeling, Demand and Price Analysis, Research and Development/Tech Change/Emerging Technologies,

CONSUMER VALUATION OF BEEF RIBEYE STEAK ATTRIBUTES

A choice experiment (conjoint analysis) was used to investigate consumer demand for several beef ribeye steak attributes. Respondents indicated that they would prefer a "hormone free" ribeye steak priced up to $6.68/lb. more than a "non-hormone" free ribeye steak. Tenderness was also identified as an important attribute in the consumer purchasing decision as a one-unit increase in the tenderness of a steak (on a scale of one to 10) was associated with a$1.13/lb. premium. Steak marbling and whether the animal was fed genetically modified corn were of less importance to consumers.Consumer/Household Economics, Food Consumption/Nutrition/Food Safety,

Higgs-photon resonances

We study models that produce a Higgs boson plus photon ($h^0 \gamma$) resonance at the LHC. When the resonance is a $Z'$ boson, decays to $h^0 \gamma$ occur at one loop. If the $Z'$ boson couples at tree-level to quarks, then the $h^0 \gamma$ branching fraction is typically of order $10^{-5}$ or smaller. Nevertheless, there are models that would allow the observation of $Z' \to h^0 \gamma$ at $\sqrt{s} = 13$ TeV with a cross section times branching fraction larger than 1 fb for a $Z'$ mass in the 200--450 GeV range, and larger than 0.1 fb for a mass up to 800 GeV. The 1-loop decay of the $Z'$ into lepton pairs competes with $h^0 \gamma$, even if the $Z'$ couplings to leptons vanish at tree level. We also present a model in which a $Z'$ boson decays into a Higgs boson and a pair of collimated photons, mimicking an $h^0 \gamma$ resonance. In this model, the $h^0 \gamma$ resonance search would be the discovery mode for a $Z'$ as heavy as 2 TeV. When the resonance is a scalar, although decay to $h^0 \gamma$ is forbidden by angular momentum conservation, the $h^0$ plus collimated photons channel is allowed. We comment on prospects of observing an $h^0 \gamma$ resonance through different Higgs decays, on constraints from related searches, and on models where $h^0$ is replaced by a nonstandard Higgs boson.Comment: 22 page

CONSUMER DEMAND FOR AND ATTITUDES TOWARD ALTERNATIVE BEEF LABELING STRATEGIES IN FRANCE, GERMANY, AND THE UK

A wide array of food safety scares and breakdowns have led to loss of consumer confidence in the quality and safety of beef products. To counteract such concerns, firms and regulators have the ability to utilize brands or labels to signal quality. Utilizing a mail survey in France, Germany, and the United Kingdom, we analyzed consumer preferences for alternative beef labeling strategies. Using an ordered probit model and a double bounded logit model, we estimate consumer preferences for alternative beef labeling programs. In general, results suggest that consumers have more confidence in government mandated labels as opposed to private brands. French and German consumers place a higher level of importance on brands and labels than do UK consumers. Results also suggest that more than 90% of surveyed consumers desire a mandatory labeling program for beef produced from cattle fed genetically modified crops.Consumer/Household Economics, Demand and Price Analysis,

DEMAND FOR BEEF FROM CATTLE ADMINISTERED GROWTH HORMONES OR FED GENETICALLY MODIFIED CORN: A COMPARISON OF CONSUMERS IN FRANCE, GERMANY, THE UNITED KINGDOM, AND THE UNITED STATES

This study compares consumer valuations of beef steaks from cattle produced without growth hormones or genetically modified corn in France, Germany, the United Kingdom, and the United States. In general, European consumers place a higher value on beef from cattle that have not been administered growth hormones and/or fed genetically modified corn than United States consumers. There is a larger divergence between the two cultures with regard to the issue of biotechnology and genetic engineering than with the issue of growth hormones. Results suggest that liberalizing trade policy for hormone-treated beef may be welfare reducing for the European Union.Consumer/Household Economics, Demand and Price Analysis, Research and Development/Tech Change/Emerging Technologies,
