Negative (But Not Positive) Parenting Interacts with Infant Negative Affect to Predict Infant Approach: Evidence of Diathesis‐Stress

Temperament by parenting interactions may reflect that individuals with greater risk are more likely to experience negative outcomes in adverse contexts (diathesis‐stress) or that these individuals are more susceptible to contextual influences in a “for better or for worse” pattern (differential susceptibility). Although such interactions have been identified for a variety of child outcomes, prior research has not examined approach characteristics—excitement and approach toward pleasurable activities—in the first year of life. Therefore, this study investigated whether 6‐month maternal reported infant negative affect—a phenotypic marker of risk/susceptibility—interacted with 8‐month observed parenting behaviors (positive parenting, negative parenting) to predict 12‐month infant behavioral approach. Based on a sample of mothers and their infants (N = 150), results indicated that negative parenting was inversely associated with subsequent approach for infants with high, but not low, levels of negative affect. Similar results did not occur regarding positive parenting. These findings better fit a diathesis‐stress model rather than a differential susceptibility model. Implications and limitations of these findings are discussed.     

Does the desire to conform to peers moderate links between popularity and indirect victimization in early adolescence?

This study of 426 Canadian early adolescents (M_age = 12.52; 53% girls) investigated whether associations between popularity and indirect victimization (i.e., reputational victimization, exclusion) varied as a function of gender and the desire to conform to characteristics and competencies that are valued within the peer group (i.e., peer conformity goals). Regression analyses revealed popularity was uniquely and positively associated with reputational victimization, but was not significantly related to exclusion after accounting for the effects of meanness and likeability. The associations between popularity and indirect victimization were moderated by peer conformity goals and gender. The results indicated that popular girls with high peer conformity goals experienced more reputational victimization and exclusion than popular girls with low peer conformity goals. However, popular boys with high peer conformity goals experienced less exclusion than popular boys with low peer conformity goals. The findings suggest that peer conformity goals carry with them some risks for popular girls, but may serve a protective function for popular boys.     

Marriage or dissolution? Union transitions among poor cohabiting women

The objective of this paper is to identify the incentives and barriers to marriage among cohabiting women, especially disadvantaged mothers who are targets of welfare reform. We use the newly released cohabitation data from the National Longitudinal Survey of Youth (1979-2000), which tracks the partners of cohabiting women across survey waves. Our results support several conclusions. First, cohabiting unions are short-lived--about one-half end within one year, and over 90% end by the fifth year. Unlike most previous research, our results show that most cohabiting unions end by dissolution of the relationship rather than by marriage. Second, transitions to marriage are especially unlikely among poor women; less than one-third marry within five years. Cohabitation among poor women is more likely than that among nonpoor women to be a long-term alternative or substitute for traditional marriage. Third, our multinomial analysis of transitions from cohabitation into marriage or dissolution highlights the salience of economically disadvantaged family backgrounds, cohabitation and fertility histories, women's economic resources, and partner characteristics. These results are interpreted in a policy environment that increasingly views marriage as an economic panacea for low-income women and their children.     

Immigrant and Native‐Born Differences in School Stability and Special Education: Evidence from New York City1

Using the literature on achievement differences as a framework and motivation, along with data on New York City students, we examine nativity differences in students’ rates of attendance, school mobility, school system exit, and special education participation. The results indicate that, holding demographic and school characteristics constant, foreign‐born have higher attendance rates and lower rates of participation in special education than native‐born. Among first graders, immigrants are also more likely to transfer schools and exit the school system between years than native‐born, yet the patterns are different among older students. We also identify large variation according to birth region.     

The Effect of Immigrant Communities on Foreign‐Born Student Achievement1

This paper explores the effect of the human capital characteristics of co‐ethnic immigrant communities on foreign‐born students’ math achievement. We use data on New York City public school foreign‐born students from 39 countries merged with census data on the characteristics of the immigrant household heads in the city from each nation of origin and estimate regressions of student achievement on co‐ethnic immigrant community characteristics, controlling for student and school attributes. We find that the income and size of the co‐ethnic immigrant community has no effect on immigrant student achievement, while the percent of college graduates may have a small positive effect. In addition, children in highly English proficient immigrant communities test slightly lower than children from less proficient communities. The results suggest that there may be some protective factors associated with immigrant community members’ education levels and use of native languages.     

Where Women Rebel

While a significant literature on women's participation in armed rebel groups exists, much of this work is focused on individual cases or regional comparisons among movements. This has led to a lack of cross-national work on women in insurgencies, and a limited understanding of the extent to which women are engaged in civil conflict internationally. This article introduces new data on women's involvement in seventy-two insurgencies active since 1990, and assesses the validity of several assumptions about women and rebellion drawn from existing literature on women in conflict and on civil wars generally. I show that women are active in rebel groups much more often than current scholarship acknowledges. This involvement includes frequent service in combat and leadership roles, where male participants are often presumed to be the default. Finally, while forced recruitment tactics are frequently used to bring women into service, much of their participation appears to be voluntary in nature.     

Ethnic Discrimination Among Recent Immigrant Adolescents: Variations as a Function of Ethnicity and School Context

This study examined ethnic discrimination among immigrant adolescents (N = 2,220) from seven ethnic groups who moved to Canada within the past 2 years. Among these newcomers attending 66 high schools, associations between discrimination and school context were explored, including indices of school composition and school climate. Results showed that less discrimination was reported in schools with higher proportions of same‐ethnicity peers and recent immigrants. Diversity support at school significantly predicted discrimination, beyond the effects of school composition. Ethnicity significantly moderated associations between diversity support and discrimination, indicating that the protective function of adults and peers at school differs for recent immigrants, depending on their ethnic background.     

Non-Gaussian Conditional Linear AR(1) Models

This paper gives a general formulation of a non-Gaussian conditional linear AR(1) model subsuming most of the non-Gaussian AR(1) models that have appeared in the literature. It derives some general results giving properties for the stationary process mean, variance and correlation structure, and conditions for stationarity. These results highlight similarities with and differences from the Gaussian AR(1) model, and unify many separate results appearing in the literature. Examples illustrate the wide range of properties that can appear under the conditional linear autoregressive assumption. These results are used in analysing three real datasets, illustrating general methods of estimation, model diagnostics and model selection. In particular, the theoretical results can be used to develop diagnostics for deciding if a time series can be modelled by some linear autoregressive model, and for selecting among several candidate models.
