Description
African American students are one of the historically disadvantaged groups by the public education system. Related to this phenomenon is the overrepresentation of African American children in special education due to disability diagnoses, which has been referred to as disproportionality. It has been hypothesized that disproportionality is due to poverty or a cultural mismatch between primarily white, middle-class teachers and African American students. Using a sample of African American children in special education from Memphis, Tennessee, this secondary data analysis explored the relationship between children's behavioral and educational outcomes and their environment, efficacy beliefs, and the impact of an intervention, the Nurse-Family Partnership. This study also explored differences in children's externalizing and internalizing behaviors by self-report, children's mothers and children's teachers. Using multiple imputation and regression analyses, the results indicated the following: 1) children's self-efficacy and number of hours in special education were associated with children's academic achievement, 2) mothers' and teachers' ratings of children's behaviors differed from children's self-report of their behaviors, 3) African American boys are more likely to experience acting-out behaviors, while African American girls are more likely to experience anxiety and depression, 4) children were less likely to experience anxiety and depression if their mother believed that she had control over circumstances in her life. These findings are discussed in light of Brofenbrenner's ecological systems theory and Bandura's social cognitive theory.

Description
Urbanization rapidly alters the environment, leading to a decrease in biodiversity in urban areas. A challenge associated with urbanized areas is the increased heat caused by the urban heat island effect. Heat may have an important impact on arthropods particularly due to their status as ectotherms. Animal behavior reveals how individuals interact with their environment. A behavioral syndrome describes consistent individual differences in behaviors that are correlated across different behavioral contexts or situations. Understanding the Western Black Widow's behavioral responses to the urban heat island effect has important implications for the control of a pest species. In this study, the relationship between rising urban temperatures and voracity, web-building, and cannibalism behaviors of juvenile Western Black Widows was examined. Spiders raised in the urban temperature treatment were predicted to have more aggressive behavioral syndromes, characterized by shorter latencies to forage, greater web-building activity, and shorter latencies to cannibalize as compared to spiders raised in rural or intermediate temperature treatments. A correlation between the latency to attack the first fly and second fly was found, however there were no other correlations evidencing a behavioral syndrome. Temperature was found to affect foraging, web-building, and cannibalism behaviors where spiders in urban areas demonstrated increased activity in all behavioral contexts. The possession of behavioral plasticity rather than a behavioral syndrome is likely what allows Black Widows to be successful urban pests.
