Ethical consumerism. How are caterers coping?
Active ethical consumerism is much less obvious in the behaviour of consumers when they eat outside the home. The catering industry argue that the majority of consumers are primarily driven by the taste of food, convenience and the service they receive when eating out. This article examines the drivers for ethical provisioning within the catering industry
PREVENTABLE FOOD BORNE ILLNESS WITH DOSE-RESPONSE DAMAGES: OPTIMAL SHARING OF PREVENTION BETWEEN CONSUMERS AND PROCESSORS AND THE EFFECT OF PRODUCT LIABILITY
As public concern for food safety burgeons concerned policy makers search for ways to manage the risk inherent to food consumption. Product liability laws may serve as efficient means to induce socially optimal levels of care or may efficiently complement regulation of potentially injurious activities. However, two characteristics common to many food borne illness cases are often not considered in the standard liability economics model that yields these prescriptions: dose-response damage functions and victim damage prevention. This paper explores how dose-response relationships common to the biology and epidemiology of food borne illness may effect the shape of resulting social welfare functions and privately chosen prevention efforts under different liability rules when both processor and consumer affect damages. Dose-response damage functions yield social objectives with multiple local optima that may dictate diametrically opposite policy prescriptions in terms of prevention sharing between consumer and processor. Small changes in the relative efficacy of either party's preventative effort may dictate discrete changes in the socially optimal prescription. Similarly, legal rules that fail to recognize both parties' contribution to damage (e.g., strict processor or consumer liability) or incorrectly define due care standards for processor negligence or contributory negligence may cause private decisions to differ discretely from socially optimal behavior.Food borne illness, dose-response, liability, Agricultural and Food Policy, Food Consumption/Nutrition/Food Safety,
Two meta-analyses of noncontact healing studies
Reviews of empirical work on the efficacy of noncontact healing have found that interceding on behalf of patients through prayer or by adopting various practices that incorporate an intention to heal can have some positive effect upon their wellbeing. However, reviewers have also raised concerns about study quality and the diversity of healing approaches adopted, which makes the findings difficult to interpret. Some of these concerns can be addressed by adopting a standardised approach based on the double-blind randomised controlled clinical trial, and a recent review restricted to such studies has reported a combined effect size of .40 (p < .001). However, the studies in this review involve human participants for whom there can be no guarantee that control patients are not beneficiaries of healing intentions from friends, family or their own religious groups. We proposed to address this by reviewing healing studies that involved biological systems other than ‘whole’ humans (i.e. to include animal and plant work but also work involving human biological matter such as blood samples or cell cultures), which are less susceptible to placebo and expectancy effects and also allow for more circumscribed outcome measures. Secondly, doubts have been cast concerning the legitimacy of some of the work included in previous reviews so we planned to conduct an updated review that excluded that work. For phase 1, 49 non-whole human studies from 34 papers were eligible for review. The combined effect size weighted by sample size yielded a highly significant r of .258. However the effect sizes in the database were heterogeneous, and outcomes correlated with blind ratings of study quality. When restricted to studies that met minimum quality thresholds, the remaining 22 studies gave a reduced but still significant weighted r of .115. For phase 2, 57 whole human studies across 56 papers were eligible for review. When combined, these studies yielded a small effect size of r = .203 that was also significant. This database was also heterogeneous, and outcomes were correlated with methodological quality ratings. However, when restricted to studies that met threshold quality levels the weighted effect size for the 27 surviving studies increased to r = .224. Taken together these results suggest that subjects in the active condition exhibit a significant improvement in wellbeing relative to control subjects under circumstances that do not seem to be susceptible to placebo and expectancy effects. Findings with the whole human database gave a smaller mean effect size but this was still significant and suggests that the effect is not dependent upon the previous inclusion of suspect studies and is robust enough to accommodate some high profile failures to replicate. Both databases show problems with heterogeneity and with study quality and recommendations are made for necessary standards for future replication attempts
Putting the pieces back together: a group intervention for sexually exploited adolescent girls
Domestic minor sex trafficking (DMST) is an emerging problem affecting adolescents, families, and communities throughout the United States. Despite a growing awareness of the problem, information regarding treatment is limited. This paper describes a pilot group intervention created for use with DMST victims, focusing specifically on areas that were critical to the development and life of the group: 1) providing education about DMST, 2) reducing shame and addressing stigma, 3) mutual aid, and 4) managing strong emotions through the development of new coping skills. Process examples are given to illustrate this pilot intervention, and recommendations for research and practice are discussed
The performance of farm animal assessment
This paper argues that the current drive towards greater use of animal-based measures for welfare assessment raises important issues for how farm visits by welfare assessors are performed. As social scientists, we employ a number of contemporary social science ideas to offer a new approach to examining the practice and performance of farm animal assessment. We identify key findings from a recent study of contemporary farm assessment and speculate upon what some of the challenges of introducing animal-based measures may be. We conclude by arguing for a greater awareness of how sets of knowledge are made, circulated, practiced and become an integral component of the procedures, practices and discourses around farm animal welfare assessment in farm assuranc
EXPLAINING ECONOMIC LINKAGES BETWEEN FARMS AND LOCAL COMMUNITIES: LOOKING BEYOND FARM SIZE
We explore the economic linkage between farms and neighboring communities using primary data collected from a state-wide cross section of 461 dairy farms. Empirical results implicate not only farm characteristics such as size, operator tenure and ethnicity but also the characteristics of the local community.Institutional and Behavioral Economics,
THE DESIGN AND PRICING OF FIXED AND MOVING WINDOW CONTRACTS: AN APPLICATION OF ASIAN-BASKET OPTION PRICING METHODS TO THE HOG FINISHING SECTOR
Asian-Basket type moving window contracts are an increasingly used risk management tool in US hog sector. The moving window contract is decomposed into a portfolio of a long Asian-Basket put and a short Asian-Basket call option. A projected breakeven price is used to determine the floor price, and then Monte Carlo simulation methods are used to price both a moving and a fixed window contract. These methods provide unbiased pricing of fixed and moving window hog finishing contracts of one-year duration.Livestock Production/Industries,
Tentative Detection of the Rotation of Eris
We report a multi-week sequence of B-band photometric measurements of the
dwarf planet Eris using the {\it Swift} satellite. The use of an observatory in
low-Earth orbit provides better temporal sampling than is available with a
ground-based telescope. We find no compelling evidence for an unusually slow
rotation period of multiple days, as has been suggested previously. A
1.08 day rotation period is marginally detected at a modest level of
statistical confidence (97%). Analysis of the combination of the
data with the ground-based B-band measurements of \citet{2007AJ....133...26R}
returns the same period (1.08 day) at a slightly higher statistical
confidence (99%).Comment: Accepted to Icarus 2008-Aug-19. 19 pages total, including 4 figures

Underpinnings for Prospective, Net Revenue Forecasting in Hog Finishing: Characterizing the Joint Distribution of Corn, Soybean Meal and Lean Hogs Time Series
This research focuses on developing a biannual net revenue forecasting model for hog producers based on Monte Carlo simulation of the joint distribution of hog, corn and soybean meal price series. The relative forecasting power of historical volatility, implied volatility and GARCH-based volatility is examined. Consistent with recent research, the performance of these three methods is both commodity and horizon specific, which means there is no single best predictor. However, implied volatility often performs well. Thus, implied volatility is used to forecast variance. Historical covariance is introduced to capture the co-movement of the three price series. Our forecasting model performs well out of sample; most of the realized net revenues fall in 95 percent prediction interval. Based on this forecasting model and the assumption of a utility function, we compare our prospective evaluation with retrospective evaluation of risk management strategies. Though prospective evaluation is not significantly superior to retrospective evaluation for this particular dataset, it is useful because all the market information has been incorporated in this model and because it did protect producers from adverse price movements.Agricultural Finance, Livestock Production/Industries,
