SU(N) Wigner-Racah algebra for the matrix of second moments of embedded Gaussian unitary ensemble of random matrices
Recently Pluhar and Weidenmueller [Ann. Phys. (N.Y.) Vol 297, 344 (2002)]
showed that the eigenvectors of the matrix of second moments of embedded
Gaussian unitary ensemble of random matrices generated by k-body interactions
(EGUE(k)) for m fermions in N single particle states are SU(N) Wigner
coefficients and derived also an expression for the eigenvalues. Going beyond
this work, we will show that the eigenvalues of this matrix are square of a
SU(N) Racah coefficient and thus the matrix of second moments of EGUE(k) is
solved completely by SU(N) Wigner-Racah algebra.Comment: 16 page

Influence of Student Characteristics, Class Size, and Instructor Characteristics in Online Student Success
The purpose of this non-experimental quantitative case study was to compare the academic success of community college students over three academic years (2016-17 through 2018-19) before the onset of COVID-19 based on final grades and the influence of student factors, class size, and faculty characteristics using archival data from selected online and on-ground classes at a Middle Tennessee community college. Student factors reviewed include gender, full-time or part-time status, and age (traditional or non-traditional status). Instructor characteristics reviewed included full-time or part-time (adjunct) teaching status and tenure or non-tenure status of faculty. Institutional data for this study consisted of 44,568 student records comprising 34,006 on-ground classes and 10,562 online classes. For the percentages provided, audit and incomplete or missing data were excluded. In this study, the mean grade point average (GPA) of all students with prior GPAs was 2.7. Unique student registrations totaled 13,400 students and unique instructors totaled 198. Eight research questions were answered from these data using Chi-square statistical tests. The final study showed a variety of results. When comparing student success for online and on-ground, online students were generally more likely to be successful, while on-ground students were generally more likely to be unsuccessful. In online courses, female students, part-time students, and non-traditional students were more likely to be successful. Class sizes fewer than 11 were generally more likely to produce successful students. Successful students were generally more likely to be taught by full-time faculty and tenured faculty
The Reincorporation of Prisoners into the Body Politic: Eliminating the Medicaid Inmate Exclusion Policy
Incarcerated people are excluded from Medicaid coverage due to a provision in the Social Security Act Amendments of 1965 known as the Medicaid Inmate Exclusion Policy (“MIEP”). This Article argues for the elimination of the MIEP as an anachronistic remnant of an earlier era prior to the massive growth of the U.S. incarcerated population and the expansion of Medicaid eligibility under the Patient Protection and Affordable Care Act of 2010. It explores three reasons for eliminating the MIEP. First, the inclusion of incarcerated populations in Medicaid coverage would signify the final erasure from the Medicaid regime of the istinction between the “deserving” and “undeserving” poor and is consistent with and in furtherance of the ACA’s ultimate goal of universal health insurance coverage. Second, elimination of the MIEP furthers the bipartisan criminal legal system reform focus on reducing recidivism through effective reentry. Current efforts to use Medicaid to facilitate reentry require careful workarounds of the MIEP. Elimination of the policy would reduce logistical hurdles to ensuring continuity of care and enhance rehabilitation services provided during incarceration. Third, eliminating the MIEP coalesces with the goals of the emerging discourse around health justice, and specifically, its focus on how social determinants of health drive inequities. In including a health justice framework, this Article seeks to enrich the discussion in two directions. In the first instance, health justice illuminates structural factors such as discrimination and poverty that are root causes of health inequities and must be addressed alongside immediate health needs. At the same time, this Article aims to deepen the health justice discussion with a sharper focus on the role of incarceration in perpetuating health inequities, and the ways in which extending Medicaid access to incarcerated populations can improve treatment of immediate needs while also addressing structural inequities that cause and are caused by justice system involvement
Imaginary in all directions: an elegant formulation of special relativity and classical electrodynamics
A suitable parameterization of space-time in terms of one complex and three
quaternionic imaginary units allows Lorentz transformations to be implemented
as multiplication by complex-quaternionic numbers rather than matrices.
