Trajectories of marijuana use and the transition to adulthood

Alongside the rise of emerging adulthood, policy contexts for marijuana have rapidly changed, with increases in availability and the number of daily users. We identify heterogeneous pathways of marijuana use from age 16 to 26, and examine how these pathways differentiate adult role transitions by age 28. Latent class analyses identified five trajectories: abstainers, dabblers, consistent users, early heavy quitters, and persistent heavy users. Dabblers are no different from abstainers on educational and labor market outcomes, and both have higher odds of adult role transitions relative to heavier use classes. Dabblers differ from abstainers on certain family transitions, yet remain distinct from the heavier use classes. Besides parenthood, early heavy quitters and persistent heavy users are similar, suggesting that heavy use is particularly detrimental early during transitions to adulthood. Distinct trajectories of marijuana use may differentiate young people into divergent pathways of transitions to adulthood, which may have long-term implications.     

Patterns of intergenerational mobility of the old and new middle classes in a post-industrial society: Netherlands 1970-2006

It has often been proposed that new cleavages have emerged within the middle class. In this paper, we examine the distinction between social and cultural specialists and technocrats, and investigate whether these new and old middle class fractions are differentiated by their patterns of intergenerational mobility. To what extent do these newly distinguished middle class fractions have specific external and internal intergenerational mobility patterns? And to what extent have mobility boundaries between them been rising over time? To answer these questions, we use 47 Dutch national population sample surveys with detailed occupation codes collected between 1970 and 2006 (N = 60,978). Our analyses of internal and external homogeneity show that the middle class fractions each have characteristic mobility and immobility patterns and therefore a necessary condition is satisfied to declare them as separate classes. Furthermore, in the early periods, the social and cultural specialists were differentiated by a high level of immobility but in the later periods, the distance between the old and new middle classes has decreased significantly.     

Extended household transitions, race/ethnicity, and early childhood cognitive outcomes

Beyond mothers’ union status transitions, other adults’ transitions into and out of the household contribute to family instability, particularly in early childhood. Using the Early Childhood Longitudinal Study-Birth Cohort (N ≅ 8550), this study examines associations between extended household transitions and age 2 cognitive development. A substantial minority of toddlers experiences these transitions, and their consequences vary by household member type, entry versus exit, and race/ethnicity. Extended household transitions predict lower cognitive scores for white children, but the selection of low-socioeconomic status families into extended households explains these disparities. Grandparent transitions predict significantly higher cognitive scores for African American and Latino children than whites, and some “other adult” transitions predict higher scores for Latinos than African Americans and whites. Extended household transitions’ consequences are independent of co-occurring residential moves and partner transitions. Findings suggest that studying extended household transitions is useful for understanding children’s early development, and their consequences vary by race/ethnicity.     

Who needs RDD? Combining directory listings with cell phone exchanges for an alternative telephone sampling frame

The traditional Random Digit Dialing method (list-assisted RDD using a frame of landline phone numbers) is clearly under threat. The difficulty and costs of completing telephone surveys have increased due to rising rates of refusal and non-contact. The completeness of coverage of list-assisted RDD samples has diminished due to the proliferation of cell-phone only households. The ability of list-assisted RDD to capture young, mobile, unmarried, and minority households is thus diminishing as well. Increasingly, survey researchers have been adding a cell phone component to their sampling frames for telephone surveys, despite the increased costs and other issues associated with RDD calling of cell phones.Recent research by Guterbock, Oldendick, and others has explored the extent to which “electronic white pages” (EWP) samples really differ from RDD samples. Oldendick et al. and Guterbock, Diop and Holian have emphasized that minority households are seriously underrepresented in EWP samples. Nevertheless, EWP samples have distinct advantages whenever a survey is aimed at a restricted geographic area.This paper considers the feasibility of combining EWP samples with cell-phone RDD, eliminating the ordinary RDD component from the sampling frame. We analyze the components of the telephone population, showing that the proposed method would fail to cover only one segment of the telephone population: unlisted landline households that have no cell phone. We analyze data from the 2006 National Health Interview Study to estimate the size of this segment, its demographic profile, the degree to which selected demographic and health behavior characteristics are different from those in the segments that this sampling strategy would capture, and what biases are present in the various sampling frames of interest. Trend data from the NHIS are used to assess how these biases are changing. A simple cost comparison is made among the RDD, RDD + cell and EWP + cell frames. The proposed alternative “EWP + cell” sampling frame provides relatively small bias compared to RDD + cell at costs comparable to RDD-only designs. The portion of the telephone universe that is excluded in the EWP + cell design is getting smaller all the time, therefore its bias relative to the RDD + cell design is decreasing over time. Overall, the EWP + cell design seems to be a useful alternative.     

Family structure and obesity in early childhood

This study informs family and child health research by using longitudinal Fragile Families data to assess how family structure and transitions are associated with changes in children’s BMI and weight status between ages three and five. Concerns in family structure literature about biases due to selectivity are reduced through the use of change score models and by controlling for parental BMI. The findings indicate unhealthy BMI gain and an increased risk of becoming overweight/obese among children living with a mother who recently dissolved a union or had been living without a partner for at least 2 years compared with those in stable married parent families. Children with single mothers who entered a new union had significantly healthier BMI trajectories than those whose mothers remained single or recently became single. These results suggest the importance of two-parent family contexts for children’s healthy physical development, and that single mothers may need additional support to better manage their children’s BMI.     

The source of Black-White inequality in early language acquisition: Evidence from Early Head Start

I compare language learning trajectories for Black and White children over the first 3 years of life using data from the Early Head Start Research and Evaluation study (EHSRE) in order to determine the timing and source of divergence in early language skill. Results indicate that that while controlling for racial differences in family background and a measure of the home language environment cannot entirely account for disparities in language acquisition, interactions between age, race and maternal education, and between race and a time-varying measure of the home language environment play a significant role. I show that returns to parental education and the home language environment, in terms of language learning, are higher for White children than their Black peers. Specification checks confirm that these results are robust to alternate definitions of child language and the home language environment, and that no interactions between race, age and any of the other covariates are significant. I discuss possible explanations for these race specific education gradients, including measurement error and test bias. In addition, I address relevant empirical issues in estimating language growth with respect to linguistic inputs and the home language environment.     

Exposure to violence,substance use,and neighborhood context

Adolescent exposure to violence and substance use are both public health problems, but how neighborhood context contributes to these outcomes is unclear. This study uses prospective data from 1416 adolescents to examine the direct and interacting influences of victimization and neighborhood factors on adolescent substance use. Based on hierarchical Bernoulli regression models that controlled for prior substance use and multiple individual-level factors, exposure to violence significantly increased the likelihood of marijuana use but not alcohol use or binge drinking. There was little evidence that community norms regarding adolescent substance use influenced rates of substance use or moderated the impact of victimization. Community disadvantage did not directly impact substance use, but the relationship between victimization and marijuana use was stronger for those in neighborhoods with greater disadvantage. The results suggest that victimization is particularly likely to affect adolescents’ marijuana use, and that this relationship may be contingent upon neighborhood economic conditions.     

Labored love: Examining the link between maternal depression and parenting behaviors

Theoretical perspectives suggest a strong link between maternal mental health and parenting, which may facilitate the intergenerational transmission of disadvantage from depressed mothers to their children. In this paper, I extend prior research by using data from the Fragile Families and Child Wellbeing Study (N = 3659). Pooled OLS and random-effects regression models document a strong link between maternal depression and the following parenting behaviors: neglect, psychological aggression, physical assault, and engagement. Fixed-effects models, however, show little evidence that changes in maternal depression are linked to changes in parenting behaviors, suggesting some negative consequences of depression are driven by variation across individuals or unobserved time-invariant characteristics. Further, the consequences of depression for parenting behaviors do not vary by mother’s marital status, suggesting that marriage may not be protective with respect to the parenting behaviors of depressed mothers.     

Neighborhood poverty and children’s exposure to danger: Examining gender differences in impacts of the Moving to Opportunity experiment

The Moving to Opportunity (MTO) program offered public housing residents in distressed communities a chance to move to low-poverty neighborhoods. The present study examined whether the resulting decline in neighborhood poverty led to lower levels of exposure to danger among children and youth ages 8-19 years old (n = 4606), and specifically, if there was a gender difference that matched the pattern of more beneficial program effects for girls and more adverse affects for boys. The study goes beyond previous research by using fixed effects to control for family factors that may influence moving behavior and confound estimates of gender differences in program impacts. Results showed that children experienced a decline in exposure to danger, with one key gender difference. Models based on brother-sister comparisons indicated that MTO had a more beneficial impact on exposure to drug activity for females than males. The findings suggest that neighborhood poverty is tied to children’s exposure to danger. Moreover, exposure to drug activity may help explain the gender differences in impacts on children’s mental health and risky behavior.     

Ethnic concentration in the neighbourhood and majority and minority language: A study of first and second-generation immigrants

Ethnic residential concentration is often found to hamper immigrants’ majority language proficiency. However, there are still several gaps in our understanding of the relationship between ethnic concentration and ethnic minorities’ language practices. This study examines the extent to which ethnic concentration also constrains immigrants’ majority language use, whether contact with natives and co-ethnics mediates these relationships, and whether ethnic concentration relates to second-generation minorities’ minority language proficiency. Structural equation models on data for people of Turkish and Moroccan origin living in the Netherlands (N = 2163) showed that ethnic concentration is indirectly related to weaker majority language proficiency and less majority language use through contact with natives and co-ethnics. For second-generation minorities, ethnic concentration is related to better minority language proficiency.     

Implicit and explicit interethnic attitudes and ethnic discrimination in hiring

We study effects of explicit and implicit interethnic attitudes on ethnic discrimination in hiring. Unlike explicit attitudes, implicit attitudes are characterised by reduced controllability, awareness or intention. Effects of implicit interethnic attitudes on ethnic discrimination in the labour market remain under-researched. Moreover, previous experiments on the effects of explicit interethnic attitudes on discrimination have important drawbacks. We use data from a laboratory experiment (n = 272) consisting of an Implicit Association Test, a questionnaire and a recruitment test in which participants reviewed résumés representing fictitious applicants who varied regarding ethnicity, gender, education and work experience. Participants graded applicants and selected applicants for an interview. Results show that only explicit interethnic attitudes affect discrimination in grades, but both explicit and implicit interethnic attitudes increase discrimination in selection.     

Imprisonment and (inequality in) population health

This article extends research on the consequences of mass imprisonment and the factors shaping population health and health inequalities by considering the associations between imprisonment and population health—measured as life expectancy at birth and the infant mortality rate—and black-white differences in population health using state-level panel data from the United States (N = 669), 1980-2004. Results show that imprisonment is significantly associated with poorer population health, though associations between imprisonment and infant mortality and female life expectancy are somewhat more consistently statistically significant than are associations with male life expectancy, and associations are more pronounced and statistically significant for blacks than they are for whites. Results also show, however, that increases in imprisonment are associated with decreases in the mortality rates of young black men. Thus, though imprisonment tends to be associated with higher mortality risk and greater black-white differences in mortality, it may, in the short-run, have some paradoxical mortality benefits for young black men.     

Irreconcilable differences? Ethnic intermarriage and divorce in the Netherlands, 1995-2008

This study uses population data of the Netherlands (municipality registers) between 1995 and 2008 to describe and explain the occurrence of divorce among recently newlywed interethnic and mono-ethnic couples (N = 116,745). In line with homogamy theory, divorce risks are higher for interethnic couples, in particular if the spouses were born and raised in countries that are culturally distant from each other. In addition, the effect of cultural distance is smaller for second generation immigrants than for first generation immigrants. There is no evidence for a higher risk of divorce among Black-White marriages. In line with convergence theory, results show that the higher the divorce propensity in the wife’s origin country, the higher the divorce risk of a couple is.     

How far do children move? Spatial distances after leaving the parental home

This research used geocoded data from 11 waves (2000-2010) of the German Socio-economic Panel Study to investigate the spatial distances of young adults’ initial move-outs (N = 2113) from their parents’ homes. Linear regression models predicted moving distances by factors at individual, family, household, and community level. Overall, home leavers moved across very small distances with a median value of less than 10 km. Greater distances were found for well-educated and childless home leavers who moved out at relatively young ages from high-income households located in less-urbanized regions. In line with developmental models of migration, young adults stayed closer if the parental household was still located at their place of childhood. We conclude that considering the spatial distance of move-outs may advance our understanding of individual passages to adulthood and intergenerational relations across the life course.     

明末清初的岭南佛寺与中外交通——以广州光孝寺和韶州南华寺为中心

明末清初的近百年间,即16—17世纪,乃西方所称的"大航海时代",葡萄牙、荷兰等早期殖民势力抵达中国南部沿海,紧随其后的传教士也接踵而来,从而拉开了中国与西方交往与冲突的序幕。明季伊始,"西洋"逐渐代替"西域"成为中西交通的主体,南海道上,来自欧罗巴的"西洋"人逐渐取代来自印度、阿拉伯的"西域"人而成为中西交流的主要对手,维持了千余年的朝贡贸易体系开始遭到西方契约贸易体系的不断撞击。岭南佛教寺院在这场"西风变换"的转折时期,扮演了某种微妙的角色:最初来华的传教士被广东地方官员视为出家僧人而安置于寺院之中;而来穗贸易、朝贡的西方商贾和使臣,虽与宗教或僧人无涉,也往往被安置于佛寺之中。这一有趣现象,反映了岭南海峤之地在中外交通中的特殊地位、朝廷对外交通政策的不确定性以及地方官员对外国人的恐惧心理。种种因缘巧合,遂使唐宋以后本已淡出中西交通主流的岭南佛寺再次成为对外交往的前沿,成为广东地方官员与来华洋人交往、周旋的中介和缓冲,见证了一系列中西交通的历史事件,在中西文化交流史上写下了有案可稽却又不太引人注目的精彩一笔。     

Risk factors and outcomes of chronic sexual harassment during the transition to college: Examination of a two-part growth mixture model

A two-part latent growth mixture model was implemented in order to examine heterogeneity in the growth of sexual harassment (SH) victimization in college and university students, and the extent to which SH class membership explains substance use and mental health outcomes for certain groups of students. Demographic risk factors, mental health, and substance use were examined as they related to chronically experienced SH victimization. Incoming freshmen students (N = 2855; 58% female; 54% White) completed a survey at five time points. In addition to self-reporting gender, race, and sexual orientation, students completed measures of sexual harassment, anxiety, depression, binge drinking, and marijuana use. Overall, self-reported SH declined upon college entry, although levels rebounded by the third year of college. Results also supported a two-class solution (Infrequent and Chronic) for SH victimization. Being female, White, and a sexual minority were linked to being classified into the Chronic (relative to the Infrequent) SH class. In turn, Chronic SH class membership predicted greater anxiety, depression, and substance use, supporting a mediational model.     

Non-standard work schedules, work-family conflict and parental well-being: A comparison of married and cohabiting unions

Although a growing number of American parents work non-standard schedules, evidence on the consequences of such working patterns is inconsistent and limited to married samples. This study highlights the importance of considering potential differences between cohabiting and married parents in terms of the relationship between non-standard work schedules and parental well-being. Based on pooled data from the 1997 and 2002 National Study of the Changing Workforce (n = 2346), we find that in contrast to married parents who experience some positive associations of non-standard schedules and parental well-being, cohabiting parents are more likely to experience a negative relationship between non-standard work schedules and parental well-being. Additionally, for cohabiting parents (but not married), non-standard work schedules are related to increased work-family conflict, which is in turn associated with lower levels of parental well-being.     

Not making the transition to college: School, work, and opportunities in the lives of American youth

Unlike traditional research on educational stratification that focuses on the pursuit of higher education, our study examines why young adults do not make the transition to college, using a nationally representative sample of college non-enrollees (N = 2640). In applying latent class analysis techniques, we identified multiple types of students who do not pursue college. One group of non-enrollees (27.6%) reports forgoing college because the economic barriers are too high - either because of college affordability or family financial responsibility. These youth had both low math test scores and low family income, and thus closely align with regression-based analyses on college enrollment that emphasize academic and economic constraints as the central barriers to educational progress. However, we also identified a second, often overlooked group of youth who had the academic preparation and family income support to enroll in higher education, but decided to forgo college because they preferred to work and to make money (18.3%). The heterogeneous motives of these youth suggest that postsecondary decisions are not always guided by academic and economic barriers, but sometimes driven by previous work experience and perceptions of local opportunities for school and work.     

The self-assessed literacy index: Reliability and validity

Literacy is associated with many outcomes of research interest as well as with respondents’ ability to even participate in surveys, yet very few surveys attempt to measure it because doing so is often complex, requiring extensive tests. The central goal of this paper is to develop a parsimonious measure of respondents’ reading ability that does not require a complex literacy test. We use data from the 2003 National Assessment of Adult Literacy to identify correlates of reading ability to form a literacy index. These correlates include self-assessments of one’s ability to understand, read and write English, and literacy practices at home. Our literacy index reliably discerns literacy test scores above educational attainment, and the index shows high internal consistency (coefficient alpha = 0.78) and validity. The paper concludes with implications of these findings for survey research practitioners and suggestions for future research.     

Estimating the prevalence of xenophobia and anti-Semitism in Germany: A comparison of randomized response and direct questioning

An experimental CATI-survey (N = 2041), asking sensitive questions about xenophobia and anti-Semitism in Germany, was conducted to compare the randomized response technique (RRT) and the direct questioning technique. Unlike the vast majority of RRT surveys measuring the prevalence of socially undesirable behaviors, only few studies have explored the effectiveness of the RRT with respect to the disclosure of socially undesirable opinions. Results suggest that the RRT is an effective method eliciting more socially undesirable opinions and yielding more valid prevalence estimates of xenophobia and anti-Semitism than direct questioning (‘more-is-better’ assumption). Furthermore, the results indicate that with increasing topic sensitivity, the benefits of using the RRT also increase. Finally, adapted logistic regression analyses show that several covariates such as education and generalized trust are related to the likelihood of being prejudiced towards foreigners and Jews.
