Psychological Determinants of Willingness to Taste and Purchase Genetically Modified Food

Decreasing acceptance of biotechnologies over time has been reported in Europe. Studies claim that attitudes are negative, even hostile, and that people are very worried about genetic engineering in food and medicine. However, such studies are mostly based on surveys and these have significant methodological problems, such as low response rates, which may indicate that only those with strong views respond, thus biasing the sample. Here an alternative method, involving "topic-blind" recruitment of participants and a behavioral measure (food tasting), was used. We show that in a topic-blind sample of 100 individuals, 93% willingly tasted and ate what they believed to be genetically modified (GM) food in an experimental setting, and 48% said they would buy GM food in the future, results that are surprising in the context of other reports about attitudes and intentions toward GM food. Purchasers and nonpurchasers differed in their attitudes toward GM food on key risk-related scales (particularly on a dread-not dread scale--a measure of integral affect--and an ethical-unethical scale). Despite these differences, however, and despite their negative attitude, most nonpurchasers (85.7%) still tasted the GM apple. Incidental affect (state stress and trait worry) was not found to influence risk-related judgments about GM food. Integral affect (dread of GM plants and animals used for food) and concerns about the future risks of GM animals in food were found to be key predictors of willingness to purchase GM food.     

Female competition: causes, constraints, content, and contexts

Monogamy tends to equalise mate competition between the sexes. However, women show greater restraint in their use of direct intrasexual aggression, which, I argue, is a result of their higher parental investment and the consequently greater reproductive cost of injury or death. Women usually compete for mates by advertising qualities valued by men (beauty and sexual exclusiveness) and by using indirect means of denigrating rivals (through gossip and stigmatisation). However, where well-resourced men are in short supply, women must find alternative sources of support or escalate their competition for male partners to physical levels. Data from criminology, psychology, evolutionary biology, and anthropology are used to support these proposals.     

The relationship between adult sexual assault and prostitution: an exploratory analysis

Previous research has established a link between childhood sexual abuse and engaging in prostitution as an adult. The purpose of this study was to extend this literature by exploring whether being raped as an adult is associated with exchanging sex for money. Interviews with 102 rape survivors in a major metropolitan area revealed that 23.5% had engaged in prostitution post-rape. Those who had exchanged sex for money were more likely to be women of color, to have a high school education or less, to be unemployed, and to have children to support, than those who had not engaged in prostitution post-assault. The prostitution subsample also had significantly higher levels of psychological distress, physical health symptomatology, and substance use. Survivors were asked whether and how the rape was associated with engaging in prostitution: most (75%) stated that they felt it was related to the assault. The most commonly cited reason for engaging in prostitution by these survivors was that they were trying to regain some control over their lives and their bodies; exchanging sex for money was seen as one way to control men's access to them. Implications for future research on victimization and prostitution are discussed.     

Part II: Death in Literature. Poetry as Epitaph

Anyone tolerably versed in American literature will realize that we could have devoted our entire collection to attitudes toward death in American literature. Such a collection could be tightly organized and valuable, but it might also be redundant for an audience which consists primarily of loosened-up literary folk to begin with. So we offer, instead of standard selections, a group of essays which, though they are about death in literature, use literature as a vehicle for discussing either theoretical or practical interpretations of death in American society and letters. Karen Campbell's essay, “Poetry as Epitaph,” uses Emily Dickinson's poetry to illustrate and embody current international theories about death and language. We place this contribution first in this section because it serves as a transition between Gravestones and Epitaphs and Death in Literature: Dickinson was writing at the same historical moment discussed by Kenneth Ames in “Ideologies in Stone,” a fact the reader may wish to remember while reading “Poetry as Epitaph;” and Karen Campbell treats Dickinson's poetry as epitaphic in style and genre. Sonia Gernes' “Life After Life: Katherine Anne Porter's Version” uses Porter's “Pale Horse, Pale Rider” to illustrate and make provocative suggestions about Raymond Moody's theses in Life After Life. Leslier Fiedler's contribution is an extract from a speech given under the auspices of an organization studying the humanist's response to child abuse, and is part of a series of lectures on that subject. He discusses infanticide through literature and then through popular culture. Marvin Kohl takes issue with some of Professor Fiedler's conclusions.     

Revealed social preference

A preliminary exploration of the possibility of recovering efficient allocations from demand and supply observations in a general equilibrium framework under alternative assumptions about the structure of individual preference.I am grateful to Larry Epstein, Mike Peters, and two referees for their comments, which led to substantial improvements. Of course, any remaining defects are attributable to the author.     

Mission statements

Mission statements now seem to be an obligatory part of a company's portfolio of literature along with a statement on environmental policy and a brochure selling the company to graduates. But what are mission statements for? How do you know if you have a good one? And can they be harmful? These are questions I have been researching on and off for 10 years.     

Estimating operational costs in an electric utility

Generation expansion planning in the electric utility industry requires consideration of uncertainties in both the demand and supply of electric power. The expected demand is usually expressed via a load-duration curve, while, on the supply side, each generating unit has a given nameplate capacity and a predicted reliability. This paper focuses on considerations of the supply-side uncertainties and their effects on estimating operating costs in electric utility planning. However, the methods and analysis developed in this paper may be applicable to a wider class of production planning problems which deal with any nonstorable product with time varying demand. Two methods for estimating the energy generation from each generating unit are compared. The first is the method of probabilistic simulation, while the second involves a heuristic technique usually denoted the derating method. A bias inherent in the derating method is examined by comparing it with a probabilistic simulation method. The bias is examined for various load curve shapes. In certain cases, a closed form expression for the bias is obtained. However, a closed form expression of the bias for an arbitrary load curve is difficult to achieve. In these situations some examples are studied in which the trend of the relative bias among plants in the loading order is examined. Finally, the bias is examined using actual 1977 load and supply data for some New England utilities.     

CANONICAL VARIATE ANALYSIS—A GENERAL MODEL FORMULATION

A general model, specifying the population means as a function of the population canonical vectors, provides a natural basis for considering many aspects of canonical variate analysis. These aspects include: estimation for elliptical densities, and robust estimation; estimation of missing values; adequacy of hypothetical variables; regression in dummy variable space; and comparison of solutions.
