Separate & Unequal: How Higher Education Reinforces the Intergenerational Reproduction of White Racial Privilege
Clearly class is a powerful cross-cutting factor in explaining postsecondary differences among all students. Yet, controlling for income, race matters: taken together, lower-income AfricanAmerican and Hispanic students just don't do as well as lower-income whites. We find that white students (45%) in the lower half of the family income distribution drop out of college much less frequently than African Americans (55%) and Hispanics (59%). These lower-income whites get Bachelor's degrees at nearly twice the rate of African Americans and Hispanics and obtain many fewer sub-baccalaureate degrees. In particular, African-American students get substantially more certificates.Class and race overlap and are most virulent in combination. Along with many other researchers, we find that the reason for persistent racial inequality begins with the fact that African Americans and Hispanics seem to face barriers not faced by whites. Unequal educational and career outcomes for economically disadvantaged whites can be explained with variables like family income, parental education, and peer expectations. These same variables do not fullyexplain African American and Hispanic educational and economic outcomes. Earlier research shows income effects are more fully explained by observable things, like peer group and tutoring, while differences by race are not so easy to pin down. The preponderance of evidence supports the premise that the disadvantages of race and income must be considered separately in most cases. Yes, differences in readiness and income explain differences in academic and life outcomes; but, independently, so do race and ethnicity
Balancing Work and Learning: Implications for Low-Income Students
This report finds that while working and studying generally helps students from higher-income families, low-income students face steeper challenges when combining work and college
Experimental hut comparisons of nets treated with carbamate or pyrethroid insecticides, washed or unwashed, against pyrethroid-resistant mosquitoes.
The efficacy against mosquitoes (Diptera: Culicidae) of a bednet treated with carbamate insecticide [carbosulfan capsule suspension (CS) 200 mg/m(2)] was compared with four types of pyrethroid-treated nets in veranda-trap huts at Yaokoffikro near Bouaké, Côte d'Ivoire, where the malaria vector Anopheles gambiae Giles carries the kdr gene (conferring pyrethroid resistance) at high frequency and Culex quinquefasciatus Say is also pyrethroid resistant. Pyrethroids compared were lambdacyhalothrin CS 18 mg/m(2), alphacypermethrin water dispersible granules (WG) 20 mg/m(2), deltamethrin 50 mg/m(2) (Permanet) and permethrin emulsifiable concentrate (EC) 500 mg/m(2). Insecticidal power and personal protection from mosquito bites were assessed before and after the nets were used for 8 months and hand washed five times in cold soapy water. Before washing, all treatments except permethrin significantly reduced blood-feeding and all had significant insecticidal activity against An. gambiae. The carbosulfan net gave significantly higher killing of An. gambiae than all pyrethroid treatments except the Permanet. Against Culex spp., carbosulfan was more insecticidal and gave a significantly better protective effect than any of the pyrethroid treatments. After washing, treated nets retained various degrees of efficacy against both mosquito genera - but least for the carbosulfan net. Washed nets with three types of pyrethroid treatment (alphacypermethrin, lambdacyhalothrin, permethrin) gave significantly higher mortality rates of Culex than in huts with the same pyrethroid-treated nets before washing. After five washes, the Permanet, which is sold as a long-lasting insecticidal product, performed no better than the other nets in our experimental conditions
15 Million Infrastructure Jobs: An Economic Shot in the Arm to the COVID-19 Recession
A 1.5 trillion will go to infrastructure) from the Biden-Harris administration would be good medicine to nurse the economic wounds inflicted by the COVID-19 pandemic. The infrastructure plan would create or save 15 million jobs over 10 years and would increase the share of infrastructure jobs from 11% to 14% of all jobs in this country, temporarily reviving the blue-collar economy
Selective Bias: Asian Americans, Test Scores, and Holistic Admissions
Selective Bias: Asian Americans, Test Scores, and Holistic Admissions evaluates the common arguments made by affirmative action critics and Students for Fair Admissions, which is suing Harvard University and has lawsuits pending against the University of North Carolina and the University of Texas at Austin over their admissions practices. The report finds no strong evidence of discrimination against Asian American applicants in admissions to highly selective colleges
Influence of Laboratory Generated Turbulence on Phase Fluctuations of a Laser Beam
An experiment is performed the aim of which is to investigate the phase fluctuations of a laser beam artificially generated thermal turbulence. This is achieved by observing the displacements of a fringe pattern obtained by means of a Mach-Zehnder interferometer. The temporal decay of the mean square refractive index fluctuation is studied. An interpretation of the results is given on the basis of the theory of an isotropic turbulent scalar field
Race, Elite College Admissions, and the Courts: The Pursuit of Racial Equality in Education Retreats to K12 Schools
If the Supreme Court bans race-conscious affirmative action, as expected, selective higher education institutions almost certainly will become less diverse, reducing the rates of degree attainment among students from historically underrepresented racial/ethnic groups. This report explores the legal history of racial equity in education, evaluates alternatives to using race/ethnicity in college admissions, and considers changes to the K–12 education system that would improve educational opportunity. In the long term, the only way to ensure diversity at selective higher education institutions is to confront the segregation and inequity in K–12 education and society at large
Flow over the Mid Adriatic Pit
The influence of the Mid Adriatic Pit (MAP) on the general circulation of the Adriatic is explored through numerical simulations. The numerical code used is the DieCAST model specifically modified for application to the Adriatic Sea. A ten-year simulation is performed and the ability of the model to capture important features of the Adriatic circulation is demonstrated. A series of numerical
experiments on the importance of the MAP on the general circulation is performed. It is demonstrated that the current over the northern flank of the MAP, which flows
from the Croatian toward the Italian coast, is primarily a topographic current and that such a current would reverse direction if the gradient of the bathymetry were
reversed
