Effects of Parental Divorce on Teenage Children’s Risk Behaviors: Incidence and Persistence

It is generally difficult to separate the effects of divorce from selection when analyzing the effects of parental divorce on children’s risk behaviors. We used propensity score matching and longitudinal data methods to estimate the effects of parents’ divorce on their children’s binge drinking, alcohol consumption, tobacco use, marijuana use, and hard drug use. The children were between 12 and 18 years old in the first survey and between 18 and 24 years old in the second survey. Our results suggest that parental divorce significantly increased the probability of risk behaviors in their children. Moreover, many of these adverse impacts persisted over time, especially among teenage girls.     

Hurricane Katrina's Impact on African Americans' and European Americans' Endorsement of the Protestant Work Ethic

The Protestant work ethic (PWE), the belief that hard work leads to success, is a quintessentially American belief. The present research addresses a critical gap in psychological research on PWE: can a single, large-scale sociopolitical event (government's response to Hurricane Katrina) produce changes in PWE? We review evidence showing that the salience of Katrina led to a reduction in African Americans' (not European Americans') endorsement of PWE and that this result appears explained by African Americans' greater belief in the government's inadequate response to Katrina victims, who were predominately African American. The implications of differential endorsement of PWE for future expectations of societal treatment, motivation to pursue important goals, and willingness to endorse structural corrections of inequality are discussed.     

Latino Phenotypic Discrimination Revisited: The Impact of Skin Color on Occupational Status

Objective . We reexamine the issue of phenotypic discrimination against Mexicans in the U.S. labor market, originally studied by Telles and Murguia (1990) and later by Bohara and Davila (1992). We also seek to explain this topic with respect to the Puerto Rican and Cuban populations in the United States. Methods . Instead of using household income as a dependent variable, we use occupational ranking scores computed by Hauser and Warren (1996) in combination with data from the 1990 Latino National Political Survey (LNPS). The occupational rankings more accurately reflect the level of labor market discrimination faced by individuals. Furthermore, the use of the more recent LNPS allows us to update the work of previous scholars and extend the analysis to two previously unexamined Latino groups—Puerto Ricans and Cubans. Results . Our findings indicate that darker-skinned Mexicans and Cubans face significantly lower occupational prestige scores than their lighter-skinned counterparts even when controlling for factors that influence performance in the labor market. However, we find no conclusive evidence that skin-color differences impact occupational prestige scores for Puerto Ricans. Conclusions . Using earlier data, some scholars found evidence for difference in labor market performance among Mexican Americans as a function of phenotypic variations among Mexican Americans. Today, dark-skinned Mexican Americans and Cuban Americans continue to face higher levels of discrimination in the labor market, whereas dark-skinned Puerto Ricans do not, which may indicate regional differences across the three groups that need to be controlled for.     

Cognitive-Affective Processing System Analysis of Reactions to the O. J. Simpson Criminal Trial Verdict

Reactions to the O. J. Simpson verdict were analyzed using the Cognitive-Affective Processing System (CAPS) model. Content analyses of participants' open-ended reactions to the verdict revealed that differences in the accessibility of cognitive-affective units and their subsequent activation pathways characterized respondents' reactions, but participants' race appeared to have no direct effect. The results were used to construct cognitive-affective domain maps that underlay elated, dismayed, and ambivalent reactions. By promoting a deeper understanding and appreciation of reactions to the verdict, we believe the domain maps facilitate overcoming the widespread tendency to attribute the cause of divergent reactions to an individual's race. The results have implications for the understanding of cultural differences.     

Marginal Changes in Random Parameters Ordered Response Models with Interaction Terms

Marginal changes of interacted variables and interaction terms in random parameters ordered response models are calculated incorrectly in econometric softwares. We derive the correct formulas for calculating these marginal changes. In our empirical example, we observe significant changes not only in the magnitude of the marginal effects but also in their standard errors, suggesting that the incorrect estimation of the marginal effects of these variables as is commonly practiced can render biased inferences on the findings.

Completing the Demographic Transition

Despite ongoing declines in fertility in many countries, the population of the world is experiencing a period of rapid expansion, and its size is expected to reach 10 billion by the end of the demographic transition. Three causes of this growth are identified and quantified: 1) fertility above the replacement level of two surviving children per woman, 2) continuing declines in mortality, and 3) population momentum resulting from a young age structure. A set of simple analytic expressions is proposed for estimating these factors from standard demographic indicators. Population momentum is shown to be the main cause of future growth in most countries and regions.     

Gendered Analyses of Nutrient Deficiencies Among the Elderly

This paper examines the factors that are associated with nutrient intake status of the elderly. Our study places special attention on the roles of physical functions, mental health, and dietary knowledge on the risk of inadequate nutrition consumption (nutrition consumption deficiencies). Using a nationwide survey of the elderly in Taiwan, we conduct empirical analysis separately by gender. Our results suggest that improving the physical conditions of male elders, the mental health of female elders, and dietary knowledge can decrease the nutrient consumption deficiencies of the elderly.

Social Class Differentials During Fertility Decline: England and Wales Revisited

This paper reviews the relationship between landholdings and fertility. Two dimensions of land are identified as salient for fertility behaviour: size of operational holdings and land ownership. It is suggested that these two dimensions and the resulting income streams have disparate effects on fertility. Size of holdings is assumed to have a positive influence on fertility due to the greater labour demands of larger holdings, while land ownership is posited to exert a negative long-term effect because of the increase in old-age security associated with the income returns to equity. In addition to these effects on the demand for children, landholding is also thought to influence the supply of children. A systematic review of the literature finds support for the impact of both dimensions of landholding on fertility preferences, contraceptive behaviour, the proximate determinants and fertility. Both the demand and supply of children appear to be influenced by landholdings. The observed regularities suggest the need for further research on this connection, not the abandonment of this line of inquiry.
