Disparities in verbal ability, a major predictor of later life outcomes, have generated widespread debate, but few studies have been able to isolate neighborhood-level causes in a developmentally and ecologically appropriate way. This study presents longitudinal evidence from a large-scale study of >2,000 children ages 6-12 living in Chicago, along with their caretakers, who were followed where...

The Medicare Advantage (MA) program continues to grow and thrive, despite plan payment cuts imposed through the Affordable Care Act. What explains this surprising outcome (one that is strikingly different than the experience of MA plans in the late 1990s, when payment cuts led to dramatic shrinkage in enrollment and curtailment of plans)? This analysis argues that a combination of factors, incl...

Sustainable competitive advantage (CA) is a necessary requirement of a rational economic business organisation. Without this CA a business does not have a rational source for appropriating added value in the form of retained profit. Various management research papers have identified numerous factors that may create a source of competitive advantage. Other researchers have shown how industries h...

This article finds that, when faced with racial inequity framed as White advantage, Whites' desire to think well of their racial group increases their support for policies perceived to harm Whites. Across 4 studies, the article provides evidence that (a) relative to minority disadvantage, White advantage increases Whites' support for policies perceived to reduce their group's economic opportuni...

abstract comparative advantage is an economic term which is used to compare potential and actual production capacity of a country in a given commodity with the rest of the world. therefore, researches in this field could have a dual approach. in one hand it could demonstrate country’s production capacity in the production of commodities that are not produced yet and in the other hand it can ill...

Lower socioeconomic status (SES) is associated with higher levels of life stress, which in turn affect stress physiology. SES is related to basal cortisol and diurnal change, but it is not clear if SES is associated with cortisol reactivity to stress. To address this question, we examined the relationship between two indices of SES, parental education and concentrated neighborhood disadvantage,...

Scholars have become increasingly interested in how social environments condition the relationships between individual risk-factors and adolescent behavior. An appreciable portion of this literature is concerned with the relationship between impulsivity and delinquency across neighborhood settings. The present article builds upon this growing body of research by considering the more nuanced pat...

Drawing from cumulative inequality theory, we examine the relationship between childhood disadvantage and health problems in adulthood. Using two waves of data from Midlife Development in the United States, we investigate whether childhood disadvantage is associated with adult disadvantage, including fewer social resources, and the effect of lifelong disadvantage on health problems measured at ...

Preterm births occur in 9.7% of all US singleton births. The rate for blacks is double that of whites and the rate is 25% higher for Hispanics than for whites. While a number of individual correlates with preterm birth have been identified, race and ethnic differences have not been fully explained. Influenced by a growing body of literature documenting a relationship among health, individual in...

As in the case of Lanczos-Lovelock gravity, main advantage F(T) gravity is said to be that it leads second order field equations, while F(R) theory fourth equations. We show rather a disadvantage, since unresolved issue `Branched Hamiltonian'. The problem bypassed F(R,T) theory.
