Race/Ethnic Differences in Effects of Family Instability on Adolescents' Risk Behavior

We used data from the National Longitudinal Study of Adolescent Health (N = 7,686) to determine whether racial and ethnic differences in socioeconomic stress and social protection explained group differences in the association between family structure instability and three risk behaviors for White, Black, and Mexican American adolescents: delinquent behavior, age at first nonmarital sex, and age at first nonmarital birth. The positive association between mothers' union transitions and each outcome for White adolescents was attenuated by social protection. The association of instability with age at first sex and first nonmarital birth was weaker for Black adolescents but not for Mexican American adolescents. The weaker association was explained by Black adolescents' more frequent exposure to socioeconomic stress in the context of union instability.     

Urbanization affects the trophic structure of arboreal arthropod communities

Urbanization is one of the most significant causes of habitat fragmentation on the planet, resulting in substantial losses of biodiversity and disruptions to ecological processes. We examined the effects of urbanization on the diversity and abundance of arboreal invertebrates in a dominant tree species (Angophora costata) in a highly urbanized landscape in Sydney, Australia, identifying the potential ecological consequences of shifts in diversity. We hypothesized that trophic structure would be influenced by landscape context with a greater richness and abundance of invertebrates in small remnants and edges. Canopy arthropods were sampled via beating from trees in 15 sites in three landscape contexts; five large patches of continuous vegetation, five edges of large patches and five small urban remnants. Trees in large patches supported fewer individuals compared to trees in small urban remnants and edge sites. The composition of assemblages and overall trophic structure also differed between edges and large patches, with a greater abundance of grazing insects in edges. No differences were detected between small urban remnants and edges, suggesting that observed differences might be attributed to an edge effect as opposed to an area effect per se. These changes in trophic structure, revealing a greater abundance of grazing herbivores and a reduced abundance of predators and parasitoids in edge sites, are consistent with work describing elevated levels of herbivory in edges of remnant vegetation. Future management of remnant urban vegetation and associated biodiversity requires not only an understanding of how trophic status influences the extent of responses by arboreal invertebrate communities, but also how these will affect ecosystem functioning.     

Discriminating positive and negative aspects of pet interaction: Sex differences in the older population

Although pet interacters from a sample of 250 persons over 50 years of age generally report receiving more intense uplifts than hassles from their pets (Chi Square = 26.7, p<0.001), there are also differences seen within this group. More specifically, differences are seen in regard to relationships between reported hassles and uplifts from pets, and socializing, life situation, and gender. For example, pet interacters who report a great deal of uplift from pets also report doing things with friends more frequently than do interacters who report only slight uplift from pets (t=2.38, p<0.05). Importantly, pets also appear to serve different roles for female and for male pet interacters, and for pet interacters in different circumstances. Uplifts from pets are associated with leisure and lack of psychological pressure for females, but are related to hassles with social interactions, time, and money for males. Contrastingly, females who report hassles from pets report hassles in the areas of free time, money, and health, but uplifts from social interactions. Human interactions with pets frequently contribute to quality of life and these interactions merit further study.     

Fertility intentions and maternal health behaviour during and after pregnancy

This study examines associations between fertility intentions and maternal health behaviours during and after pregnancy among a nationally representative sample of 3,442 women from India. Two waves of data (2005, 2012) from the India Human Development Survey were analyzed to investigate the influence of unwanted births on women’s use of antenatal care, timely postnatal care, and the delivery setting using binary and ordered logistic regression, partial proportional odds models, and propensity score weighting. Fifty-eight per cent of sample births were unwanted. Regression results show that, net of maternal and household characteristics, women with unwanted births were less likely to obtain any antenatal care and had fewer antenatal tests performed. Unwantedness was also associated with a lower likelihood of delivering in an institutional setting and of obtaining timely postnatal care. The relationships between unwantedness and antenatal care, postnatal care, and delivery setting were robust to models accounting for propensity weighting.     

Student well-being: Are they better off now?

Past and present well-being of university students from Canada and the United States are compared. Ratings for the domains of health, recreation, self-esteem, and education decreased significantly between the 1984 measures and the 1992 measures. Canadian students generally rated the domains lower than did students from the United States. Self-discrepancy measures tended to decrease and hope measures for the United States students indicated less hopefulness now than in 1984. In general, student perceptions of well-being seem poorer now than in the past.A path analysis revealed that MDT predicted 39 percent of the variance for satisfaction and 45 percent for happiness. Empirical support is provided for most of the hypothesized paths and for self esteem and social support as conditioners of well-being. The results are consistent with cultural convergence and theories of well-being that incorporate both actual world changes and individual perception of those changes.     

Regional Tertiary Students and Living Away from Home: A priceless experience that costs too much?

For financial reasons, an increasing number of tertiary students in Australia are forced to work long hours each week, and they are becoming more likely to be living in relative poverty. This study aimed to explore and describe the economic situation of students at a provincial Australian university campus, and the role that type of residence plays in their financial well‐being. A large‐scale self report survey dealing with students' financial experiences during the 2003 academic year, was distributed to a convenience sample of students from across the courses offered on the campus. Quantitative data analysis was completed using SPSS and qualitative data was analysed thematically. Results indicate a strong relationship between type of residence and financial well‐being. Rural students may be especially vulnerable to the effects of financial distress, because of issues such as low cash‐flow on many family farms, and the long distances many travel to attend regional universities. This study indicates a number of possible avenues to protect students from living in poverty.     

Are maternal and community risk factors associated with the presence of asthma among children placed in foster care?

Objective

The occurrence of pediatric asthma has been associated with exposure to chronic stress. This study examined the relationship between maternal and community risk factors and asthma in a sample of maltreated children in foster care.

Method

Interviews were conducted with 365 maltreated children in foster care. Measures included youth/caregiver reports of asthma, an index of maternal risk based on data abstracted from child welfare records and community violence exposure.

Results

After controlling for demographic variables, maternal risk was associated with the presence of asthma (OR = 1.314, 95% CI = 1.09–1.58). Community violence exposure, however, was not related to the presence of asthma.

Conclusion

Maternal risk factors were significantly associated with the presence of asthma in a foster care population. Physicians who care for maltreated children in foster care should be particularly attuned to the presence of these additional risk factors that may place high-risk children at increased risk for chronic health problems.     

Inside Community Aid Abroad Part III: Community Work Works: The path to development requires a self-sustaining community development process.

In the third of a series of four articles, Scott Christie describes a typical Community Aid Abroad project and shows how Community Aid Abroad puts the community work approach into practice. He contrasts this with aid projects which follow more of a case-work approach and finally uses a Brotherhood of St. Laurence evaluation framework to measure the achievements of the example project in community work terms.
