On average, the parental practices adopted by African American parents of young children are much less cognitively stimulating than those of their white counterparts. This paper argues that these differences stem from the low rates of return to human capital historically experienced by African Americans. To study the relationship between the race-specific returns to skill and parenting, I use i...

The frequency of the 235T and 174M alleles of the angiotensinogen gene, previously reported to be associated with hypertension in Caucasians and Japanese, was compared between 57 hypertensive African Americans and 130 normotensive African Americans sampled as part of a community survey of hypertension in the Chicago area. The frequency of the 235T allele was unrelated to hypertension status (ca...

Background There is limited knowledge about the use of cigarettes by blacks outside the United States (U.S). Nigeria creates an opportunity to explore smoking behaviours, smoking cessation (nicotine dependence) and use of cigarettes in a country that has a large black population outside the U.S.   Methods We conducted three Focus Group Discussions (FGDs) involving twenty-four male migrant worke...

Game parks in Tanzania have long been considered to be at low risk for African trypanosomiasis; however, nine cases of the disease associated with these parks were recently reported. The outbreak was detected through TropNetEurop, a sentinel surveillance network of clinical sites throughout Europe.

OBJECTIVE Exposure to racial discrimination has been identified as an adverse biopsychosocial stressor that may be related to the prevalence of hypertension in African Americans. The overall objective of this research was to estimate aspects of the effects of self-reported exposure to stress-related racial discrimination and hypertension likelihood in a sample of African Americans. DATA Physi...

conclusions large-scale studies on the healthy black african population could assess the relationship between diastolic dyssynchrony and changes in myocardial performance related to racial differences. results the frequency of some dyssynchrony markers was similar to that of other studies. the difference between maximal time-to-peak systolic velocity and minimal time-to-peak systolic velocity w...

In order to study the signs of œstrus in the West African Dwarf goat, 28 non pregnant females younger than 24 months of age were used. Most of them (94.7%) had waggled the tail during heat. The frequency of micturition was higher in the presence of the male. The swelling of the vulva was observed in 68.4% of goats in heat. The cervico-vaginal mucus was significantly (P≤0.05) abundant and elasti...

REASONS FOR PERFORMING STUDY African horse sickness is an insect-transmitted, noncontagious disease of equids caused by African horse sickness virus (AHSV). Mortality can exceed 90% in fully susceptible horse populations. A live-attenuated (modified live) cell-culture-adapted (MLV) polyvalent AHSV vaccine is widely used to control African horse sickness in endemic areas in southern Africa. Fiel...
