Characterizing The Molecular And Cellular Changes Of Senescent Cells Induced By Diverse Stressors In 2d And 3d Microenvironments, Apoorva Chauhan

UNLV Theses, Dissertations, Professional Papers, and Capstones

Aging is a risk factor for myriad diseases and is often associated with the accumulation of senescent cells. Cellular senescence, a process of irreversible cell cycle arrest, is associated with various changes in cellular morphology and function. While senescence will occur naturally in a time-dependent manner, it can be prematurely induced by various extrinsic and intrinsic factors. Most senescence studies model cell behavior in two-dimensional (2D) microenvironments; however, these models are not physiologically relevant. In this study, the effects of naturally occurring reactive oxygen species (ROS) hydrogen peroxide (H2O2) and commonly used chemotherapy drugs, doxorubicin and palbociclib, on cellular senescence …

Big Capital & The Carceral State, Laura I. Appleman

UC Law Journal

Who is accountable for the imposition of punishment in our carceral system? The answer used to be much simpler, as we held local, state, and federal government actors responsible. In recent decades, however, our correctional system has become increasingly privatized, with deeply troubling results. All aspects of the carceral state—whether prisons, jails, juvenile detention, rehabilitation, forensic hospitals, bail, or electronic monitoring—have dramatically increased their use of privatized correctional services.

With this new world of privatized corrections, we frequently don’t know whom can be held accountable when wrongdoing occurs. The bulk of our correctional services are now provided by complicated web …

A Review Of Training For First Responders When Interacting With Individuals With Diagnoses, Mackenzie Drost, Robbie Hanson

Theses

Safety is a priority for first responders when responding to calls, but there have been numerous cases in which unintentional harm was caused when interacting with individuals with diagnoses or disabilities. Thus, it seems as though effective training procedures for these professionals is critical. However, training for first responders varies from state to state and can depend on the county in which the services are provided. Although behavioral skills training (BST) has a well-established history of training non behavior-analytic professionals and although there have been some encouraging recommendations for the effective dissemination of applied behavior analysis (ABA) to those outside …

Pressured Exit, Jayesh Rathod

Scholarly Articles in Law Reviews & Journals

This Article upends the traditional framing of the United States as a migrant-receiving country by examining a growing category of emigrant outflows: U.S. citizens who have been compelled to depart permanently because of conditions of vulnerability. Eschewing use of the generic term "expatriate," this Article contends that these U.S. citizens are most accurately described as pressured migrants who have exited due to identity-based mistreatment, gaps in the social safety net, or concerns about deteriorating social and political conditions in the United States. By focusing on these departures, this Article aims to further theorize and provide a lexicon for a subtype …
