FACTORS AFFECTING CONSUMER NEGATIVE PERCEPTIONS ABOUT BEEF IRRADIATION

This study has identified several important factors affecting consumer negative perceptions about beef irradiation. The effects of these factors boil down to two main points: lack of trust in the adequacy and enforcement effectiveness of food safety regulations and consumer ignorance about the irradiation process. This implies dissemination of information about food irradiation and enhancement of consumer trust in the mechanism of food safety regulation can be effective instruments to increase consumer acceptance of beef irradiation.Consumer/Household Economics,

A VALUATION OF PUBLIC DEMAND FOR THE PARTICIPATION OF NONGOVERNMENTAL AGENCIES IN MONITORING AND ENFORCING FOOD SAFETY REGULATIONS

Lack of consumer trust in governmental food safety regulators hinders the promotion of consumer confidence in the safety of their food supply. One possible way to boost consumer trust is to allow nongovernmental agencies to participate in monitoring and enforcing food safety regulations. This study identifies factors affecting consumer desire for the participation of nongovernmental agencies. The information obtained from this study can be used in further valuation of the feasibility of the participation of nongovernmental agencies.nongovernmental agencies, food safety regulations, Food Consumption/Nutrition/Food Safety,

THE EFFECTS OF IRRATIONAL RESPONSES IN CONTINGENT VALUATION SURVEY AND THE APPROPRIATE TREATMENT

This paper investigates the effects of irrational responses on stated willingness-to-pay (WTP) in a contingent valuation study. A significant portion of the respondents stated that they were willing to pay a higher price for irradiated beef which they would avoid consuming due to their concerns about the side effects of irradiation. Such responses may not reflect true WTP and may cause bias in WTP estimate. Excluding these responses from estimation may result in sample selection bias. Whereas setting the bid values presented to these responses close to zero both helped to improve the estimation model and to reduce the potential bias in WTP estimate.beef irradiation, irrational response, willingness-to-pay, Consumer/Household Economics,

CONSUMPTION OF REDUCED-FAT PEANUT BUTTER IN ADDITION TO THE CONSUMPTION OF REGULAR PEANUT BUTTER

A set of factors has been identified to affect consumption of reduced-fat peanut butter in addition to regular peanut butter. We found that consumption of reduced-fat peanut butter, which is an imperfect substitute for regular peanut butter, may expand total demand for peanut butter. Interestingly, for those who usually buy the same brand of peanut butter, their consumption of reduced-fat peanut butter is more likely in addition to consumption of regular peanut butter, implying promotion of a specific brand of reduced-fat peanut butter tend to increase total demand for the same brand of peanut butter.reduced-fat peanut butter, regular peanut butter, Consumer/Household Economics,

RESEARCH SPILLOVERS AND RETURNS TO WHEAT RESEARCH INVESTMENT

This study evaluates the rates of return to US wheat research investment, focusing on research spillovers. Results show that research spillovers exist among various classes of wheat. Due to the spillover effects, social rates of return to research investment are substantially higher than the corresponding private rates of return.Research and Development/Tech Change/Emerging Technologies,

Radiomics for Response and Outcome Assessment for Non-Small Cell Lung Cancer.

Routine follow-up visits and radiographic imaging are required for outcome evaluation and tumor recurrence monitoring. Yet more personalized surveillance is required in order to sufficiently address the nature of heterogeneity in nonsmall cell lung cancer and possible recurrences upon completion of treatment. Radiomics, an emerging noninvasive technology using medical imaging analysis and data mining methodology, has been adopted to the area of cancer diagnostics in recent years. Its potential application in response assessment for cancer treatment has also drawn considerable attention. Radiomics seeks to extract a large amount of valuable information from patients' medical images (both pretreatment and follow-up images) and quantitatively correlate image features with diagnostic and therapeutic outcomes. Radiomics relies on computers to identify and analyze vast amounts of quantitative image features that were previously overlooked, unmanageable, or failed to be identified (and recorded) by human eyes. The research area has been focusing on the predictive accuracy of pretreatment features for outcome and response and the early discovery of signs of tumor response, recurrence, distant metastasis, radiation-induced lung injury, death, and other outcomes, respectively. This review summarized the application of radiomics in response assessments in radiotherapy and chemotherapy for non-small cell lung cancer, including image acquisition/reconstruction, region of interest definition/segmentation, feature extraction, and feature selection and classification. The literature search for references of this article includes PubMed peer-reviewed publications over the last 10 years on the topics of radiomics, textural features, radiotherapy, chemotherapy, lung cancer, and response assessment. Summary tables of radiomics in response assessment and treatment outcome prediction in radiation oncology have been developed based on the comprehensive review of the literature
