Gender Differences in Concern with Body Weight and Physical Appearance Over the Life Span

Abstract: Age, gender, and gender role differences on a set of variables including concern with eating, body weight, and physical appearance, global self-esteem, and appearance self-esteem were examined in a sample of subjects consisting of 639 visitors to a participatory science museum. Their ages ranged from 10 to 79 years. Results showed that females are more concerned than males about eating, body weight, and physical appearance and have lower appearance self-esteem. More important, these gender differences are generally apparent at all ages. The importance of gender differences across the life span in appearance concern and appearance self-esteem is discussed.

Prospect theory: an analysis of decision under risk

Abstract: This paper presents a critique of expected utility theory as a descriptive model of decision making under risk, and develops an alternative model, called prospect theory. Choices among risky prospects exhibit several pervasive effects that are inconsistent with the basic tenets of utility theory. In particular, people underweight outcomes that are merely probable in comparison with outcomes that are obtained with certainty. This tendency, called the certainty effect, contributes to risk aversion in choices involving sure gains and to risk seeking in choices involving sure losses. In addition, people generally discard components that are shared by all prospects under consideration. This tendency, called the isolation effect, leads to inconsistent preferences when the same choice is presented in different forms. An alternative theory of choice is developed, in which value is assigned to gains and losses rather than to final assets and in which probabilities are replaced by decision weights. The value function is normally concave for gains, commonly convex for losses, and is generally steeper for losses than for gains. Decision weights are generally lower than the corresponding probabilities, except in the range of low prob- abilities. Overweighting of low probabilities may contribute to the attractiveness of both insurance and gambling. EXPECTED UTILITY THEORY has dominated the analysis of decision making under risk. It has been generally accepted as a normative model of rational choice (24), and widely applied as a descriptive model of economic behavior, e.g. (15, 4). Thus, it is assumed that all reasonable people would wish to obey the axioms of the theory (47, 36), and that most people actually do, most of the time. The present paper describes several classes of choice problems in which preferences systematically violate the axioms of expected utility theory. In the light of these observations we argue that utility theory, as it is commonly interpreted and applied, is not an adequate descriptive model and we propose an alternative account of choice under risk. 2.

The Framing of Decisions and the Psychology of Choice

Abstract: The psychological principles that govern the perception of decision problems and the evaluation of probabilities and outcomes produce predictable shifts of preference when the same problem is framed in different ways. Reversals of preference are demonstrated in choices regarding monetary outcomes, both hypothetical and real, and in questions pertaining to the loss of human lives. The effects of frames on preferences are compared to the effects of perspectives on perceptual appearance. The dependence of preferences on the formulation of decision problems is a significant concern for the theory of rational choice.

The Dutch Eating Behavior Questionnaire (DEBQ) for assessment of restrained, emotional, and external eating behavior.

Abstract: The development of the Dutch Eating Behaviour Questionnaire (DEBQ) with scales for restrained, emotional, and external eating is described. Factor analyses have shown that all items on restrained and external eating each have high loadings on one factor, but items on emotional eating have two dimensions, one dealing with eating in response to diffuse emotions, and the other with eating in response to clearly labelled emotions. The pattern of corrected item-total correlation coefficients and of the factors was very similar for various subsamples, which indicates a high degree of stability of dimensions on the eating behavior scales. The norms and Cronbach's alpha coefficients of the scales and also the Pearson's correlation coefficients to assess interrelationships between scales indicate that the scales have a high internal consistency and factorial validity. However, their external validity has yet to be investigated.

The Dimensions, Antecedents, and Consequences of Emotional Labor

Abstract: This article conceptualizes the emotional labor construct in terms of four dimensions: frequency of appropriate emotional display, attentiveness to required display rules, variety of emotions to be displayed, and emotional dissonance generated by having to express organizationally desired emotions not genuinely felt. Through this framework, the article then presents a series of propositions about the organizational-, job-, and individual-level characteristics that are antecedents of each of these four dimensions. Frequency of emotional display, attentiveness to display rules, variety of emotions to be displayed, and emotional dissonance are hypothesized to lead to greater emotional exhaustion, but only emotional dissonance is hypothesized to lead to lower job satisfaction. Implications for future theory development and empirical research on emotional labor are discussed as well.
