<h3>Thurgood Marshall.</h3>
Explanation:
Thurgood Marshall was the first Supreme Court justice of African descend. He was a lawyer by profession and played an important role in bringing racial equality and liberty during the Civil Rights Movement.
Marshall became a lawyer for the National Association for the Advancement of Colored People (NAACP) and it was during this time he served as chief attorney for the plaintiffs in Brown v. Board of Education of Topeka. He successfully led the case and won a unanimous verdict against school segregation.
This case helped him gain lots of recognition and admiration. President Johnson appointed him as the first African-American Supreme Court justice in 1967.
Homicide is one of the leading causes of death among African-American and Hispanic men. We investigated how neighborhood characteristics associated with social disadvantage explain racial/ethnic homicide gaps in 10 U.S. cities. The test hypotheses were that (1) higher concentrations of African-Americans and Hispanics would be associated with higher homicide rates and (2) the relationship between racial/ethnic concentration and homicide would be attenuated after adjusting for neighborhood characteristics (e.g., unemployment, median household income, low educational attainment, and female headship). The test hypotheses were examined using separate Poisson regression models, which adjusted for spatial autocorrelation. Homicide rates were greater in neighborhoods with higher concentrations of African-Americans and Hispanics than in other groups, and the association of neighborhood racial/ethnic concentration with homicide was reduced after adjusting for neighborhood social disadvantage variables, especially percent female head of household and percent persons with less than a high school education. We also found that the relationship between neighborhood racial/ethnic concentration and homicide was explained more by social disadvantage variables in some cities than in others. Based on our findings, policy makers may wish to consider implementation of policies that (1) expand early childhood education programs and higher education opportunities and (2) encourage economic and community development initiatives in socially disadvantaged neighborhoods.
