Measuring cultural bias in a cross-national study

Cross-national research claims increasing attention, due in part to a growing awareness of worldwide interdependence. One of the most intriguing areas of research is the comparison of perceptions about the quality of life. However, even the first attempt to compare cross-national quality of life perceptions (Cantril, 1965) raised a question which still remains unanswered: What do the differences between countries mean? Presumably differences in income, in the objective conditions of the major life domains such as housing, health and employment, and in demographic variables account for some of the difference among countries' reported quality of life satisfaction. But how can these factors be separated from other non-random factors? The term we use for the latter is “cultural bias”. By cultural bias we mean the systematic cross-national differences in quality of life perceptions which are not explained by objective measures of quality of life nor by demographic factors. Ordinarily these culture-specific biases are acquired during the socialization process almost as automatically and unconsciously as one learns one's mother tongue. Cultural bias is manifested in the tendency for members of a particular culture to be optimistic or pessimistic, confident or cautious in evaluating their social and physical environment and in revealing these evaluations to others. Thus, our conception of cultural bias has something in common with the idea of national character, but it is more limited in scope. In this paper we discuss the problem of isolating the impact of cultural bias from the other factors affecting how people perceive their quality of life and measuring it. We describe a method which is capable of doing this and report the results of using it to measure the relative cultural bias between respondents in Springfield, Illinois and Aixen-Provence, France.     

Race, racial resentment, attentiveness to the news media, and public opinion toward the Jena Six

Objective. We outline the role of race, racial resentment, and attentiveness to news in structuring public opinion toward the prosecution of the Jena Six, the name given to six African-American high school students who beat a white student, five of whom were subsequently charged with attempted second-degree murder.Method. We rely on a telephone survey of 428 registered voters collected in the aftermath of the protests in Jena, Louisiana.Results. Public reactions were heavily filtered by race and associated with measures of racial resentment. African Americans followed news about the protests more closely, believed race was the most important consideration in the decision to prosecute, and believed the decision to prosecute was the wrong decision. Racially conservative white respondents were less likely to believe race was the most important consideration in the decision to prosecute and were more likely to believe that the decision to prosecute was the right decision. Consistent with theories of agenda setting and framing, attentiveness to the news influenced perceptions regarding the importance of race in the decision to prosecute but not whether the decision was the right decision.Conclusions. At least within the context of the Deep South, race and racial attitudes continue to be an important predictor of public reactions to racially charged events. Attentiveness to the news influenced the lens through which events were interpreted, but not perceptions of whether the outcome was the right decision.     

Predicting objective physical activity from self-report surveys: a model validation study using estimated generalized least-squares regression

Physical activity measurements derived from self-report surveys are prone to measurement errors. Monitoring devices like accelerometers offer more objective measurements of physical activity, but are impractical for use in large-scale surveys. A model capable of predicting objective measurements of physical activity from self-reports would offer a practical alternative to obtaining measurements directly from monitoring devices. Using data from National Health and Nutrition Examination Survey 2003–2006, we developed and validated models for predicting objective physical activity from self-report variables and other demographic characteristics. The prediction intervals produced by the models were large, suggesting that the ability to predict objective physical activity for individuals from self-reports is limited.     

THE INFLUENCE OF OPEN AND CLOSED BELIEF SYSTEMS ON COOPERATION IN THE PRISONER'S DILEMMA*

The Rokeach Dogmatism Scale was employed to identify subjects possessing either open or closed belief systems. Forty-eight subjects were randomly selected and assigned to eight open-open, eight open-closed, and eight closed-closed pairs. The dyads then played a modified version of the Prisoner's Dilemma where they were also permitted to communicate using a predetermined list of messages. It was found that the eight open-open pairs cooperated significantly more than the other pairs in the experiment. However, results also suggest that individuals possessing open belief systems may not be able to achieve significantly greater cooperation with individuals possessing a closed belief system than two individuals both possessing closed belief systems.     

Rationing Capacity Between Two Product Classes*

In this paper, we study the capacity allocation problem faced by make-to-order manufacturing firms encountering expected total demand in excess of available capacity. Specifically, we focus on firms' manufacturing short-life-cycle or seasonal products such as high fashion apparel. Using a decision-theory-based approach, we develop a capacity allocation policy that allows such firms to discriminate between two classes of products (one yielding a higher profit contribution per unit of capacity allocated to it than the other), resulting in selective rejection of orders for the class with the lower unit contribution. The effectiveness of capacity rationing is investigated under a wide array of conditions characterized by variations in factors such as the ratio of unit profit contributions of the two product classes, the ratio of total available capacity to expected total demand, the ratio of expected demands between the two classes, and the variability in demand for each product class. The results indicate that capacity rationing is very effective in increasing the total profit, and could therefore serve as a valuable decision tool for managers in such firms.
