During the COVID-19 pandemic, wastewater-based epidemiology has emerged as a promising approach for monitoring SARS-CoV-2 prevalence on a community-level. Despite much being known about the utility of making these measurements in large wastewater treatment plants, little is known about the correlation with finer geographic resolution, such as those obtained through sewershed sub-area catchments. This study aims to identify community wastewater surveillance characteristics between sewershed areas that affect the strength of the association of SARS-CoV-2 RNA detection in a metropolitan area. For this, wastewater from 17 sewershed areas were sampled in Louisville/Jefferson County, Kentucky (USA), from August 2020 to April 2021 …

Sorry, They Were On Mute: The Sec’S “Token Proposal 2.0” As Blueprint For Regulatory Response To Cryptocurrency, J. Scott Colesanti

Hofstra Law Faculty Scholarship

In 2008, as the world dreaded economic meltdown, one or more anonymous individuals titled "Nakomoto" posted a scientific white paper on the Internet. "Bitcoin" was thus born. That name - uttered but once in the white paper- would go on to define a movement, a market, and a mountain.

By late 2010, approximately 100 bitcoin had been mined; two years later, that number approached 10 million, and a second crypto had emerged. By 2018, bitcoin traded at over $18,000 per coin; a year later, that market value had plummeted to less than $5,000. Concurrently, tales of digital asset fortunes lost …


Choosing Death, Shaping Death: Assumptions About Disabilities, Race, And Death, Janet L. Dolgin Jan 2022

Choosing Death, Shaping Death: Assumptions About Disabilities, Race, And Death, Janet L. Dolgin

Hofstra Law Faculty Scholarship

This article considers two legal cases and the stories that developed around them. Both the cases and their stories involved issues of significance to the larger society - death and bias. Each concern has occasioned confusion and debate in its own right. When these issues are combined, confusion and debate are intensified. This Article examines the complicated interplay between bias and decisions about death and dying in the U.S. health care system. Further, it reviews intersecting claims about the importance, respectively, of autonomy and community in resolving disputes about the topics of death and dying.

Transactional Clinical Support For Mutual Aid Groups: Toward A Theory Of Transactional Movement Lawyering, Michael Haber

Hofstra Law Faculty Scholarship

In response to the global spread of the COVID-19 pandemic in the spring and summer of 2020, thousands of grassroots, participatory, and often social movement-connected community efforts to help feed and care for one another through the crisis were launched, many of which identified their projects as 'mutual aid'. This article tells the story of how the Hofstra Law School Community Economic Development ("CED") Clinic has provided legal support and information to hundreds of these COVID-19 mutual aid groups. The article briefly reviews Professor Dean Spade's 2020 book Mutual Aid: Building Solidarity During This Crisis (and the Next), contrasting it …


Wrongful Imprisonment And Coerced Moral Degradation, G. Alex Sinha, Janani Umamaheswar Jan 2022

Wrongful Imprisonment And Coerced Moral Degradation, G. Alex Sinha, Janani Umamaheswar

Hofstra Law Faculty Scholarship

Despite the ever-growing number of exonerations in the U.S.— and the corresponding surge in scholarly interest in wrongful convictions in recent years—research on the carceral experiences of wrongfully-convicted persons remains strikingly limited. In this essay, we draw on in-depth interviews with 15 exonerated men to explore the moral dimensions of the experience of wrongful imprisonment. We argue that imprisonment entails what we refer to as “coerced moral degradation,” whereby innocent men’s self-preservation efforts in prison require them to feign being—and at times actually become— morally worse people. We argue that these findings speak to the fundamental question of what the …

The Elephant In The Room In Clinical Scholarship: Ethical Guardrails And Case Histories, Theo Liebmann, Stefan H. Krieger

Hofstra Law Faculty Scholarship

Lawyers know how to tell a good story and are expected, encouraged, and even ethically required to use that skill on behalf of their clients. More and more, lawyers and legal academics are now using their clients' stories to advance goals that go far beyond achieving a client's objectives: exposing inequities with regard to access to justice; educating the public about the functioning and limitations of the legal system; raising the quality of lawyering; and improving our system of legal education. Unfortunately, the increase in the use of case histories to achieve such laudable goals has not been paired with …

Research Outputs: 2025-Present

B-site ordered 4d1 and 5d1 double perovskites have a number of potential exotic ground states including multipolar order, quantum spin liquids and valence bond glass states. These arise from the complex interactions of spin-orbital entangled Jeff = 3/2 pseudospins on the geometrically frustrated fcc lattice. The 4d1 Mo5+ perovskite Ba2YMoO6 has been suggested to have a valence bond glass ground state. Here we report on the low temperature properties of powder samples of isostructural Ba2LuMoO6: the only other known cubic 4d1 perovskite with one magnetic cation. Our …

Trapped On The Eve Of War, 1941: Stalin And His Generals Failing Separately And Together, Cynthia A. Roberts Jan 2022

Trapped On The Eve Of War, 1941: Stalin And His Generals Failing Separately And Together, Cynthia A. Roberts

Publications and Research

This chapter examines Soviet military planning and preparedness on the eve of Germany’s June 1941 invasion of the Soviet Union. Drawing on archival evidence and post-Soviet scholarship, it reassesses explanations for the Red Army’s catastrophic initial defeats. It argues that the General Staff’s unrealistic offensive plans and force posture conflicted with Stalin’s political strategy of deterrence and war avoidance. This mismatch, rooted partly in the Soviet military’s organizational preference for offensive operations and flawed assumptions about mobilization and the initial period of war, increased Soviet vulnerability to surprise attack. The chapter considers the development of Soviet war plans in 1940–1941, …

Reinventing Public Healthcare In India, Milind Kokje Jan 2022

Reinventing Public Healthcare In India, Milind Kokje

Asian Review

The outbreak of COVID-19 exposed the gaps and shortcomings in the Indian public healthcare System. The Indian healthcare system is a glaring example of two extremes of positive and negative. The Constitution of India does not guarantee health as a fundamental right, though the Indian judiciary, through its several judgements, has interpreted the concerned articles to expand their scope to include the right to health. India’s achievements in developing healthcare infrastructure, having more health personnel in service etc. are still much less than the requirement and below global benchmarks. It has launched the world’s largest health insurance scheme. Still, the …


Reconsidering Social Protection For Motorcycle Taxi Drivers: Understanding Precarity In Formalized Informality, Kritsada Theerakosonphong Jan 2022

Reconsidering Social Protection For Motorcycle Taxi Drivers: Understanding Precarity In Formalized Informality, Kritsada Theerakosonphong

Asian Review

This article's central argument is that as a consequence of ride-hailing applications (apps), formalized informality has emerged among motorcycle taxi drivers (MTDs). The aim is to provide preliminary recommendations for reconsidering social protection (SP) for MTDs. Platformization and practices of precarising formality through formal-informal interaction are reviewed, as well as employment status and other different forms of employment. MTDs are unevenly matched in power relations dominated by the government and non-government officials, insecurity and uncertainty related to job precarity results. Several critical SP issues are discussed including: the distinction between formality and informality and the related inability to divide the …
