Thomas, Kristina Pattison, Suneel Kumar, Gagana Karkada, Duncan Trosan, Aunic Goodin, Jason Rainone, Dnyaneshwari Rananavare, Vandana Miller, Francois Berthiaume, Katharina Stapelmann

Kimmel Cancer Center Faculty Papers

Cold atmospheric plasmas (CAP) are a versatile tool in medical applications like wound healing. Its therapeutic benefits are partially attributed to the generation of biologically active reactive oxygen and nitrogen species (RONS). Characterization of RONS, however, typically only occurs after treatment. Here we report the first real-time in situ detection of CAP-generated nitric oxide (NO), and the simultaneous detection of cellular calcium ions (Ca²⁺) release using electrochemical sensors during CAP treatment of murine wounds. In vivo, NO rose rapidly within the first minute of CAP treatment but accumulated less overall than in PBS, reflecting reactions with wound-bed targets. In situ …

Learned Resiliency: Lived Experiences Of First Responders, Kevin Francis Sullivan

The research study was grounded in Heidegger’s philosophy of hermeneutic phenomenology, guided by resiliency theory , and informed by post-traumatic growth theory. Seven first responders from multiple disciplines were invited to participate in semi-structured interviews designed to provide rich and reflective …

The Safety Net And The Gig Economy: Policy Attitudes And Political Participation, Juhyun Bae, Jake Haselswerdt

School of Political Science, Public Affairs, Legal and Security Studies Faculty Publications

The emergence of the so-called gig economy has reshaped the labor market and, potentially, the politics of the safety net. Much of the American welfare state is based on a traditional model of employment, excluding most gig workers from benefits like subsidized employer-provided health insurance and unemployment insurance. Despite these trends, there is little research on how these changes might affect politics. Are gig workers likely to become a relevant constituency on social welfare and other issues? To address this, we conducted a unique online survey examining policy attitudes and political behaviors among gig workers compared with traditional workers. Our …

The Evil Historical Twin: How The Requirement Of A Historical Analogy Could Result In Further Discrimination In The Law, Bryanna Mall

The Scholar: St. Mary's Law Review on Race and Social Justice

In 2024, the Supreme Court decided the case of United States v. Rahimi. The Court, unpersuaded by Rahimi’s objection regarding federal law which prohibited an individual subject to a domestic violence restraining order from possessing a firearm, decided the restriction was constitutional. While the holding of this case represents a win for survivors of domestic violence, the legal reasoning plants itself of flimsy concepts of history. The Court utilized a historical analysis test and looked to precedent rooted in social customs, legislation, and court holdings. The first major issue of this test is the dueling interpretation between a historical …
