The Efficacy Of A Service-Learning Experience In The New Orleans Area In Improving Intercultural Competence Of Nutrition And Dietetics Students, Michel D. Harris
The Efficacy Of A Service-Learning Experience In The New Orleans Area In Improving Intercultural Competence Of Nutrition And Dietetics Students, Michel D. Harris
UNF Graduate Theses and Dissertations
There is a large gap between minority representation in the field of dietetics and the United States population, and nutrition students need advanced cultural competence training in preparation for future work with diverse populations. Universal recommendations for delivering and evaluating cultural competence training in nutrition programs are non-existent, and students tend to lack understanding of how to develop this skill. Service-learning in underserved communities with reflective assignments have been used to develop cultural competence skills, but most reported results are anecdotal. This non-randomized mixed methods study sought to find out if a service-learning experience improves intercultural competence of nutrition students …

Ai And Gender In Persuasion: Using Chatbots To Prevent Driving Under The Influence Of Marijuana, Victoria Halfacre
Research Papers
Will new media techniques, such as artificial intelligence (AI), help refresh public safety advertising campaigns and help better target specific populations, and aid in persuasive, preventative marketing? This paper used hypocrisy induction as a persuasive tool for standalone artificial intelligence chatbots to test potential behavioral change in the context of marijuana. This research further tested whether the chatbots' gender and language styles impact how persuasive and effective the chat agents are perceived to be using hypocrisy induction. An online experiment conducted with 705 participants (Mage = 42.9, 392 women). where participants interact with a chatbot that is manipulated …

The Entity Attorney-Client Privilege Meets The Twenty-First Century: Rethinking Functional Equivalent Analysis In The Time Of A Nonemployee Workforce., Grace M. Giesel
The Entity Attorney-Client Privilege Meets The Twenty-First Century: Rethinking Functional Equivalent Analysis In The Time Of A Nonemployee Workforce., Grace M. Giesel
Faculty and Staff Scholarship
Courts have struggled with whether an entity’s attorney-client privilege can protect communications between the entity’s lawyer and a nonemployee who has information the entity’s lawyer needs to best advise the entity. The nonemployee might be a former employee. But increasingly in recent times, the nonemployee is an individual who was never an entity employee. Corporations and other entities have incorporated nonemployees in their economic enterprises in all sorts of roles—roles employees may have held in the past. Many courts have accepted that the privilege can apply to communications involving former employees.
When faced with nonemployees who are not former employees, …
On (Not) Seeing The Chicken: Perdue, Animal Welfare, And The Failure Of Transparency, Calvin Coker, Rachel A. Coker
On (Not) Seeing The Chicken: Perdue, Animal Welfare, And The Failure Of Transparency, Calvin Coker, Rachel A. Coker
Faculty and Staff Scholarship
In this essay, we analyze Perdue’s animal welfare campaign from 2016 to 2020 to isolate how demands for transparency are mediated and subverted by Perdue’s public facing rhetoric. Though Perdue’s annual releases and commitments to change nominally constitute a victory for animal welfare advocates, the company’s campaign enacts transparency as a sort of publicity for the company that belies marginal gains for the lives of chickens and may ultimately result in increased meat consumption. In providing trackable metrics, offering paternalistic justifications for their treatments of chickens, and through strategic omissions of language and visuals, Perdue satisfies demands for transparency without …
Cambridge 1629 Anglican Trilogy, Dale B. Billingsley
Cambridge 1629 Anglican Trilogy, Dale B. Billingsley
Faculty and Staff Scholarship
In 1629, Thomas and John Buck, Cambridge University Press printers, published three texts—the Book of Common Prayer, the Bible and the Whole Book of Psalmes (known as the “Metrical Psalter”)—that were often bound together in one volume [UL], 1 one copy of which is now on permanent loan to the Archives & Special Collections of Ekstrom Library, University of Louisville. We do not know with any certainty when UL was bound, but because the KJV second edition was published in 1638, with many scholarly corrections based on the original languages, we can assume that the three texts were bound together …

Cooperation Without Convergence: Border Carbon Adjustment And Heterogeneity Of Climate Actions, Lucas Moreira Jiminez
Cooperation Without Convergence: Border Carbon Adjustment And Heterogeneity Of Climate Actions, Lucas Moreira Jiminez
LL.M. Essays & Theses
Border Carbon Adjustment measures (“BCAs”) were originally conceived to help solve a problem that arises when countries ask firms to internalize the costs of environmental depredation in an open economy. Environmental regulation raises costs to domestic producers who feel and are — both are relevant — disadvantaged vis-à-vis their foreign competitors subject to lower regulatory costs, in ways that impact economic competitiveness but also the effectiveness of the regulation itself, to the extent it is directed at a ‘global commons’ problem such as reducing greenhouse gas (“GHG”) emissions in an attempt to mitigate climate change. However, BCAs create issues of …
Conflicting Fundamental Rights Under The Indian Constitution: Analyzing The Supreme Court’S Doctrinal Gap, Nikhil Pratap
Conflicting Fundamental Rights Under The Indian Constitution: Analyzing The Supreme Court’S Doctrinal Gap, Nikhil Pratap
LL.M. Essays & Theses
The Constitution of India recognizes a wide variety of fundamental rights: civil and political, socio-economic, and group rights. A conflict between these rights is a common occurrence. The Supreme Court of India’s method of resolving conflicts has been ad-hoc, nebulous, and vague. The Court rarely locates the conflict at a granular level and, on the rare occasion that it does, the decision lacks comprehensive reasoning. This paper attempts to demonstrate the doctrinal, structural, and reasoning gap in the Court’s jurisprudence. The paper does so by analyzing a subset of cases where the Court has adjudicated on conflicts between the right …

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 …

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
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 …

Reinventing Public Healthcare In India, Milind Kokje
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
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 …
