Relationship between major risk factors of sudden infant death syndrome (SIDS) and sleep disorders in the infants is the subject of review and discussion. Improper micro-environmental characteristics (especially poor environmental organisation and lack of developmental stimulation), pre-term delivery and/or infant low birth weight, prone sleep…

Recent studies reveal early and wide gaps in cognitive and oral language skills--whether gauged in English or Spanish--among Latino children relative to White peers. Yet, other work reports robust child health and social development, even among children of Mexican American immigrants raised in poor households, the so-called "immigrant…

Increased attention is being paid to open adoption arrangements between birth parents and adopted children and families. This study examines openness and contact among 469 adoptions at 14 years postadoption from the fourth wave of the California Long-Range Adoption Study (CLAS) and 378 adoptions matched across all waves.

In the article "Cohort Effects on Non-marital Fertility," in this issue of "Social Forces," Jean Stockard employs a novel strategy for disentangling cohort, period, and age effects on the non-marital fertility ratio. In a model with fixed-effect controls for age and for time period, the author documents evidence for three cohort-specific factors…

We use data from the earlier and later cohorts of the NLSY to estimate the effect of marriage and childbearing on wages. Our estimates imply that marriage lowers female wages 2-4 percent in the year of marriage. Marriage also lowers the wage growth of men and women by about two and four percentage points, respectively. A first birth lowers female…

Research that is conducted across divergent contexts and communities presents challenges. This paper explores the importance of building trusting relationships between researchers and participants to overcome some of these challenges. Using a postmodern perspective it describes practices that merged to form a comprehensive strategy for working…

Under the conditions of the market, the development of the economy must be of priority to the state, for the state cannot exist and be dynamic without such an economy and, consequently, there can be no question of any transformation of marriage, family relations, and the birthrate. A vital task in the development of the state has to do with…

The aim of this study is to analyze the health care costs of violence against women. For the study, we used a register-based approach where we identified victims of violence and assessed their actual health care costs at individual level in a bottom-up analysis. Furthermore, we identified a reference population. We computed the attributable costs,…

We are facing rapid changes in the global climate, and these changes are attributable to human behavior. Humans produce this global impact through our use of natural resources, multiplied by the vast increase in population seen in the past 50 to 100 years. Our goal in this article is to examine the underlying psychosocial causes of human impact,…

The goals of this study were to examine longitudinal changes in perceived control in adolescents' sibling relationships and to describe the nature and correlates of three distinct control patterns: firstborn dominant, equal, and secondborn dominant. Firstborn and secondborn adolescents in 184 predominately European-American families participated…

Using social control theory and attachment theory as guides, this study examined how qualities of young adolescents' social relationships (i.e., mother, sibling, and friend) and dynamic interactions among characteristics of those relationships are associated with school involvement and delinquency. The participants included older siblings (M age =…

Using the first nationally representative birth cohort study in Taiwan, this paper examines the role that maternity leave policy in Taiwan plays in the timing of mothers returning to work after giving birth, as well as the extent to which this timing is linked to the amount of time mothers spend with their children and their use of breast milk…

The aim of the study was to investigate the relationship between the Flynn effect and the effects of age differences between siblings on the intelligence difference between them. In Norway, the secular trends in intelligence-test score means vary both in magnitude and direction. We identified three periods: one period where the mean intelligence…

Restless Development's youth-led model places trained Volunteer Peer Educators (VPEs), aged 18-25 years, in schools to teach HIV prevention and reproductive health (RH). VPEs also run youth centers, extracurricular and community-based activities. This evaluation assesses (i) program effects on students' HIV/RH knowledge, attitudes and behaviors…

Research indicates a continued need for understanding how and why physicians select certain CME courses, as well as the differences between CME course takers and nontakers. Purpose: Obstetrician-gynecologists (OB-GYNs) are health care…
