An Introduction To Numerical Relativity And Simulations Of Binary Neutron Stars
The theory of general relativity is currently the best description of gravity. However, the equations in general relativity are highly nonlinear and only the simplest of cases can hope to be solved analytically. As a result, the field of numerical relativity was created to solve some of these issues and to model more complicated dynamical situations. This thesis sets out to give the reader a basic understanding of general relativity, numerical relativity, as well as an understanding of some of the programs that are used in numerical relativity research such as Lorene and the Einstein Toolkit and concludes with a brief set of simulations of binary neutron stars with various masses

Better estimates from binned income data: Interpolated CDFs and mean-matching
Researchers often estimate income statistics from summaries that report the
number of incomes in bins such as \$0-10,000, \$10,001-20,000,...,\$200,000+.
Some analysts assign incomes to bin midpoints, but this treats income as
discrete. Other analysts fit a continuous parametric distribution, but the
distribution may not fit well.
We fit nonparametric continuous distributions that reproduce the bin counts
perfectly by interpolating the cumulative distribution function (CDF). We also
show how both midpoints and interpolated CDFs can be constrained to reproduce
the mean of income when it is known.
We compare the methods' accuracy in estimating the Gini coefficients of all
3,221 US counties. Fitting parametric distributions is very slow. Fitting
interpolated CDFs is much faster and slightly more accurate. Both interpolated
CDFs and midpoints give dramatically better estimates if constrained to match a
known mean.
We have implemented interpolated CDFs in the binsmooth package for R. We have
implemented the midpoint method in the rpme command for Stata. Both
implementations can be constrained to match a known mean.Comment: 20 pages (including Appendix), 3 tables, 2 figures (+2 in Appendix
Adultification: Addressing the injustice faced by young girl of color in the school system
Adultification is a form of racial prejudice involving children of a racialized minority being treated as more mature than their biological age and reasonable social standards of development. It “reduces or removes the consideration of childhood as a mediating factor in Black youths’ behavior” (Epstein et al., 2017, p. 2). Adultification leads to a higher prevalence of sexualization, more frequent punishment, and increased alienation of young Black girls within the public school system. This is a systemic issue which requires systematic solutions. The most effective solution would be to diversify the workforce
