Although it has been suggested that obesity is 'contagious' within the social network, direct cause of this spread of obesity remains unclear. This study hypothesized that Body Image (BI), the perception of one's own body size, may play a role in this obesity spread, since a high prevalence of obesity could shift people's perception of 'what is normal'. Young Japanese females (n = 53) were interviewed within 1 month after moving to New York City, where the prevalence of obesity is substantially higher than that of their home country, Japan. Each participant was examined for her BI in terms of current body size (CBS) and ideal body size (IBS). They were interviewed again 2 months after the first examination. Between the two interviews, the participants' CBS was decreased (having thinner self-image), while the IBS increased (having fatter ideal-image), leading to less dissatisfaction (smaller CBS-IBS) with their body size. These results suggest that one's BI could change in a period as short as 2 months, possibly because of being surrounded by more obese people. The IBS change was positively associated with BMI change (increased by 0.4 ± 0.6 kg/m²), warranting further study on the role of BI in the spread of obesity. [ABSTRACT FROM AUTHOR]

Rectangularization of human survival curves is associated with decreasing variability in the distribution of ages at death. This variability, as measured by the interquartile range of life table ages at death, has decreased from about 65 years to 15 years since 1751 in Sweden. Most of this decline occurred between the 1870s and the 1950s. Since then, variability in age at death has been nearly constant in Sweden, Japan, and the United States, defying predictions of a continuing rectangularization. The United States is characterized by a relatively high degree of variability, compared with both Sweden and Japan. We suggest that the historical compression of mortality may have had significant psychological and behavioral impacts. [ABSTRACT FROM AUTHOR]

The effects of education on current migration propensities in the United States are examined for each age group, and an estimate is made of how these age-specific differentials cumulate over a lifetime in determining the number of times that individuals at different educational levels can expect to move over the course of their lives. The independent effects of age, education, and occupation are also examined. Two other sections investigate trends in educational selectivity of migration in the United States and international comparisons of occupational differences in migration. [ABSTRACT FROM AUTHOR]

This paper examines empirically whether more stringent domestic environmental policies reduce the international competitiveness of environmentally sensitive goods (ESGs). Our time series evidence indicates that there are no systematic changes in trade patterns of ESGs in thelast three decades, despite the introduction of more stringent environmental regulations in most of the developed countries in the 1970s and 1980s. This observed phenomenon is then subjected to a multi-country econometric test using an extended gravity-equation framework. The test suggests that, overall, more stringent environmental regulations do not reduce total exports, exports of ESGs and exports of non-resource-based ESGs. Neither was there any evidence to support the hypothesis that new trade barriers emerge to offset the effects of more stringent environmental regulations. [ABSTRACT FROM AUTHOR]

This study examines perceived risk data from the U.S., China, Japan,and South Korea. These data are then compared with similar results collected from previous studies. Psychometric scaling scores from Burkino Faso (a West African country), France, Norway, and Hungary have been analyzed and compared with results from our study. The data reveal certain risk events like nuclear weapons, war, and AIDS to have high perceived risks in all countries. These data also show that many ofthe events have dissimilar perceived risks in different countries. The conclusions also show some countries have higher over all levels of perceived risk (South Korea) while others like the United States display generally lower values. [ABSTRACT FROM AUTHOR]
