The Immigrant Paradox in Pregnancy: Explaining the First‐Generation Advantage for Latina Adolescents

The immigrant paradox is a population health pattern whereby later generation immigrant youth display less favorable outcomes when compared to first‐generation co‐ethnic peers. This study examines the role of number of sex partners in explaining the immigrant paradox in pregnancy among Latina adolescents. This secondary analysis utilized a nationally representative sample of Latinas in the National Longitudinal Study of Adolescent Health. As expected, first‐generation Latina adolescents demonstrated less risk than second‐ or third+ generation Latinas for becoming pregnant. Further, the lower number of sexual partners fully accounted for the first generation's advantage in lower rate of adolescent pregnancy. These findings have important implications for healthcare providers who work with Latina girls in pregnancy prevention.     

Cultural pluralism and the future of American unity: the impact of illegal aliens

This paper explores the question of the impact of illegal migration on American unity and cultural pluralism in the US. Assuming that over time the descendants of undocumented workers now in the US will behave substantially like descendants of those who immigrate legally, the long-term impact of illegal migration barely will be noticeable provided it is reduced substantially in the future. The process of acculturation will work in the same way for both groups as it has for other ethnic groups in the past, given comparable levels of education and length of family residence in the US. The author takes special notice of the illegal migration of Spanish-speaking workers and hypothesizes that the behavior of their descendants will not differ from that of the descendants of other immigrants, legal or illegal, in ways that disrupt fundamental patterns of American political unity and cultural pluralism.     

Variance estimation when donor imputation is used to fill in missing values

Donor imputation is frequently used in surveys. However, very few variance estimation methods that take into account donor imputation have been developed in the literature. This is particularly true for surveys with high sampling fractions using nearest donor imputation, often called nearest‐neighbour imputation. In this paper, the authors develop a variance estimator for donor imputation based on the assumption that the imputed estimator of a domain total is approximately unbiased under an imputation model; that is, a model for the variable requiring imputation. Their variance estimator is valid, irrespective of the magnitude of the sampling fractions and the complexity of the donor imputation method, provided that the imputation model mean and variance are accurately estimated. They evaluate its performance in a simulation study and show that nonparametric estimation of the model mean and variance via smoothing splines brings robustness with respect to imputation model misspecifications. They also apply their variance estimator to real survey data when nearest‐neighbour imputation has been used to fill in the missing values.

Linkages between Children's Beliefs about the Legitimacy of Aggression and Their Behavior

The purposes of this study were to learn whether children's beliefs about the legitimacy of aggression can be reliably assessed and whether these beliefs relate to children's everyday social behavior with peers, as well as their responses to hypothetical ambiguous provocation situations. Fourth- and fifth-grade students ( n = 781) responded to a 16-item questionnaire designed to measure children's beliefs about the legitimacy of aggression. Children's behavioral orientation was assessed using two methods: (1) children's responses to ten hypothetical situations involving ambiguous provocation, and (2) peer evaluations of children's aggressive, withdrawn, and prosocial behavior. Results indicated that children's beliefs about the legitimacy of aggression were reliably measured. Furthermore, results from both measures of behavioral style showed that children who believed strongly in the legitimacy of aggression were more aggressive, less withdrawn, and less prosocial. The findings suggest that one focus of efforts to decrease children's aggression should be the modification of their beliefs about the legitimacy of aggressive actions.     

Economic and environmental concerns as influences on growth attitudes: A research note

Two sets of items from Albrecht et al. (1986) are used to examine small town residents’ attitudes about the environment and the economy. One scale measures a general growth ethic while the other measures attitudes concerning urban growth. Concern over the environment and the economy are assessed with items drawn from Blocker and Eckberg (1989). Results indicate that environmental concerns are a stronger influence on growth attitudes than are economic considerations and that certain sociodemographic variables are weakly associated with this tendency. In the small town population studied, which is in the process of making decisions about growth, environmental concerns play a stronger role in influencing attitudes about growth than do concerns over the economy.

The Nonmetro/metro Context of Racial/ethnic Outmarriage: Some Differences between African Americans and Mexican Americans1

Abstract Data from the 1990 U. S. Census are used to examine nonmetro-metro distinctions in the outmarriage patterns of the nation's two largest minority groups—African Americans and Mexican Americans. The analysis is guided by a multilevel model combining individual- and community-level determinants of outmarriage. Consistent with notions suggesting that persons in metro areas are less traditional and, perhaps, more tolerant of those different from them, we find that African Americans living in metro areas are more likely to be married to someone from another racial/ethnic group than their peers in nonmetro areas, even after residential differences in individual and community characteristics are taken into account. On the other hand, controlling for other factors, Mexican Americans living in metro areas are not any more likely than those living in nonmetro settings to be exogamous. One possible explanation for this divergent pattern is the relatively recent urbanization of the Mexican American population.     

Evaluating Risk Communications: Completing and Correcting Mental Models of Hazardous Processes, Part II

We propose a decision-analytic framework, called the mental models approach , for evaluating the impact of risk communications. It employs multiple evaluation methods, including think-aloud protocol analysis, problem solving, and a true-false test that allows respondents to express uncertainty about their answers. The approach is illustrated in empirical comparisons of three brochures about indoor radon.
