The time is ripe to strengthen the mathematics capacity of inner-city high schools, creating wider access to powerful and exciting mathematics courses for public high school students in America's cities. A particular national weakness is that a significant percent of urban secondary schools offer no calculus course. Access and availability to a curriculum comparable to that offered in virtually every suburban and private high school is denied these students.

Abstract Nearly 1,000 officer-involved killings occur each year in the United States. This article documents the large, racially disparate effects of these events on the educational and psychological well-being of Los Angeles public high school students. Exploiting hyperlocal variation in how close students live to a killing, I find that exposure to police violence leads to persistent decreases in GPA, increased incidence of emotional disturbance, and lower rates of high school completion and college enrollment. These effects are driven entirely by black and Hispanic students in response to police killings of other minorities and are largest for incidents involving unarmed individuals.

Background: This study was designed to measure the prevalence of chronic gingivitis among 16- year-old public high school students in Khartoum State.Methods: A total of 385 high school students of 16 years of age, from public schools in different geographical locations representing different socioeconomic classes in Khartoum were randomly selected and examined. The variables of the present study had been collected by one examiner using a direct interview questionnaire and all the present teeth were examined at four sites (Mesiobuccal, distobuccal, mesiolingual, distolingual) for the presence of plaque, using the Plaque Index (Loe and Sillness) and Gingival Index (Sillness and Loe).Results: Prevalence of gingivitis was 96.9%, of which 68.6% were of mild form (majority), 27.5% of moderate condition and only 0.8% was of severe grade. The most common form of gingivitis was the generalized form that accounted for 94.5%. The relationship between oral hygiene and degree of gingivitis was assessed after collecting data on study area, gender, socio-economic status, tooth brushing tool used, frequency of brushing per day, direction of tooth-brushing and regularity of dental visits. The adjusted relationship was still significant at the 99% confidence level (p-value 0.000), with a correlation coefficient of 0.704.Conclusions: The study showed significantly higher prevalence of chronic gingivitis among 16-year-old public high school students in Khartoum State. The degree of gingivitis showed statistical significance when correlated with oral hygiene status, socioeconomic status, frequency and horizontal direction of tooth brushing, while it showed insignificance when correlated with gender. Med Phoenix.

An upward trend of psychoactive drug use within the lower grade levels was observed among 616 high school students. Although different patterns of drug use exist between parochial and public high school sophomores, by their junior year the two groups were similar. Over half of the public high school students claimed they take drugs either “for kicks” or “for curiosity”.
