Acknowledged but Ignored: A Critical Race Theory Approach to the Prison Rape Elimination Act
No full textFollowing the work of Michelle Alexander, Kevin Medina and Brian Nguyen’s “Acknowledged but Ignored: A Critical Race Theory Approach to the Prison Rape Elimination Act,” address the overrepresentation of incarcerated men of color, speci cally African American men. Medina and Nguyen highlight the ways in which racism and homophobia reproduce rape culture in prisons and demonstrate the limitations of the Prison Rape Elimination Act
The Characterization of Circular Extrachromosomal rDNA Elements in Naegleria SPP
No full text2024ABSTRACT Naegleria are unicellular, eukaryotic amoebas characterized by their ability to shift between multiple life stages. These organisms are ubiquitous in nature and found in bodies of freshwater and soil. The Naegleria life stages include: the trophozoite stage, a growth and replication stage characterized by pseudopodic movement, the cyst stage, a hibernation stage characterized a double-walled membrane, and the flagellate stage, a mobility stage that is characterized by the presence of flagella. Naegleria are predominantly non-pathogenic except for Naegleria fowleri, which is the only species of Naegleria to cause disease in humans. Organisms of the Naegleria genus are further characterized by a circular extrachromosomal rDNA element (CERE) that is localized to the nucleolus. The CERE is unique because it contains the genes for rDNA production, which are not found in the chromosome. Naegleria species contain thousands of copies of the CERE which can replicate autonomously and independently of the chromosome. To date, the full-length CERE sequences were only known for different strains of N. gruberi, N. fowleri, and N. lovaniensis.
We investigated the CERE further by studying N. gruberi and other Naegleria species that represent varying levels of phylogenetic relatedness to N. gruberi: N. australiensis, N. jadini, and N. pringsheimi. Long-read sequencing of these CERE demonstrated a unique sequence composition for each species, predominantly within the non-ribosomal sequence (NRS). Sequencing revealed sizes ranging from 11.8 kbp in N. jadini up to 16.1 kbp in N. pringsheimi. Analysis of the full-length CERE indicate potential shifts in phylogenetic relatedness between species as well as the presence of predicted structures such as G-quadruplexes that are both unique and conserved across the genus.
We further explored the molecular dynamics of the N. gruberi CERE by transfecting cells with the molecular clone, pGRUB. Transfection with pGRUB demonstrated transient propagation across several culture passages, encystment and excystment. N. gruberi trophozoites transfected with constructs that either have or do not have the putative ori demonstrated diminished propagation, indicating other components of the NRS may be necessary for replication.
The objectives of this research were to provide further understanding of the Naegleria CERE and to significantly contribute to the Naegleria sequence database. The data from these results will function as a basis study the characteristics of N. fowleri and non-pathogenic Naegleria

A powder neutron scattering study of magnetism in potassium copper trifluoride as a function of hydrostatic pressure
No full textPresented here are elastic neutron scattering pressure studies investigating the magnetic ordering of KCuF3 under hydrostatic pressure. Recent studies have predicted the magnetic ordering to be modified at P ~ 7 kbar due to a glassy structural transition. Single crystal studies by Alexander Thaler of the MacDougall lab indicated relative peak intensities of the (001) and (003) magnetic Bragg peaks were not suppressed with pressure. Interestingly, the suppression of the (201) magnetic Bragg peak was observed. These results are believed to be due to a spin reorientation caused by a uniaxial strain component caused by using a clamp cell. Single crystal measurements also identified that the Néel temperature increased by approximately 1.6 K with 1.07 GPa applied pressure. We were motivated to further investigate the magnetic ordering of KCuF3 in a manner which mitigates the effect of the uniaxial strain on the magnetic properties of the material. Therefore, powder measurements were performed in various cell types. My work found that the ordered moment in powder samples under pressure does not appear to significantly change the magnetic ordering in this material up to P ~ 8 kbar, suggesting that the prediction of modified magnetic ordering due to a glassy structural transition does not occur.Submission original under an indefinite embargo labeled 'Open Access'.

Out of sight but not out of mind: Home countries’ macroeconomic volatilities and immigrants’ mental health
No full textWe provide the first empirical evidence that better economic performances by immigrants’ countries of origin, as measured by lower CPI or higher GDP, improve immigrants’ mental health. We use an econometrically-robust approach that exploits exogenous changes in macroeconomic conditions across immigrants’ home countries over time and controls for immigrants’ observable and unobservable characteristics. The CPI effect is statistically significant and sizeable. Furthermore, the CPI effect diminishes as the time since emigrating increases. By contrast, home countries’ unemployment rates and exchange rate fluctuations have no impact on immigrants’ mental health
