Rule 4 And Personal Jurisdiction, Scott Dodson Jan 2023

Rule 4 And Personal Jurisdiction, Scott Dodson

Faculty Scholarship

State-court personal jurisdiction is regulated intensely by the Fourteenth Amend- ment’s Due Process Clause, which the Court has famously used to tie state-court personal jurisdiction to state borders. Although the Fourteenth Amendment doesn’t apply to federal courts, the prevailing wisdom is that federal courts nevertheless are largely confined to the same personal-jurisdiction limits as state courts because of Rule 4(k), which provides that service “establishes personal jurisdiction” in federal court only upon specified conditions, including when the state courts would have personal jurisdiction. Some commentators have further argued that Rule 4(k) sets a limit on federal-court personal jurisdiction independent of …

Misinformation And Covid-19, Dorit Rubenstein Reiss Jan 2023

Misinformation And Covid-19, Dorit Rubenstein Reiss

Faculty Scholarship

The COVID-19 pandemic’s impact on our world cannot be overstated. One of its noticeable features was the prominence of misinformation generally, and anti-vaccine misinformation more specifically. This article provides a breakdown of the five major themes of antivaccine misinformation and the way they were used to create fear, uncertainty, and doubt about COVID- 19 vaccines. Long before the pandemic, anti-vaccine activists argued using a five-part playbook. They argued that (1) vaccine preventable diseases were not really dangerous, (2) vaccines were dangerous and ineffective, (3) there were alternative treatments that were better than (dangerous and ineffective) vaccines, (4) there was a …


Empowering Victims Of Grand Corruption: An Emerging Trend, Naomi Roht-Arriaza Jan 2023

Empowering Victims Of Grand Corruption: An Emerging Trend, Naomi Roht-Arriaza

Faculty Scholarship

Who is the victim of systemic corruption? The traditional answer in law is everyone and no one, or public administration itself. When state funds are misused or go missing, at the most the State is the victim. Therefore, only the State has standing to sue for, or receive restitution of, the stolen assets. But that long-held consensus is changing. Activists and lawyers have begun to argue that under systematic corruption it’s not just states, but individuals and communities as well as society as a whole that suffer losses and need to be both represented and repaired. Courts are beginning to …

Suing Spacs, Emily Strauss

Faculty Scholarship

In 2020, the financial world became transfixed by a massive increase in the number of firms going public through special purpose acquisition company (“SPAC”) transactions. A SPAC is a publicly traded company formed solely for the purpose of raising money from investors and choosing a merger partner, thereby bringing the target company public. SPAC shareholders vote on the proposed transaction, but also have the option to redeem their shares for the price paid plus interest prior to the merger. SPACs have always been controversial; they make risky ventures available to unsophisticated investors, may involve acute conflicts of interest, and do …


Rewarding Failure With Patents, Robin Feldman Jan 2023

Rewarding Failure With Patents, Robin Feldman

Faculty Scholarship

It is axiomatic that patents promote success. And yet, a contrary notion—that the patent incentive for medicine should be sufficient to compensate for the losses incurred when other research fails—is quietly permeating modern court decisions, commentary, and Congressional discussions, coloring debates relating to pricing and regulation of medicine. The conceptualization is moving forward unchallenged, as if failure compensation follows logically from the innovation incentives built into the patent construct. As this Article demonstrates, however, the notion is antithetical to patent law, putting modern conceptualizations on a collision course with the history and theory of patents reaching back to this nation’s …

The Uncertain Future Of Restorative Justice: Anti-Woke Legislation, Retrenchment And Politics Of The Right, Thalia Gonzalez, Mara Schiff Jan 2023

The Uncertain Future Of Restorative Justice: Anti-Woke Legislation, Retrenchment And Politics Of The Right, Thalia Gonzalez, Mara Schiff

Faculty Scholarship

As diverse forms of anti-democratic and anti-inclusionary politics escalate in the United States, public education is increasingly a site for retrenchment and contestation with targeted efforts to silence and erase civil rights victories for equity and access. Addressing a critical, yet unattended issue at the intersection of education law and policy and civil rights, this Article joins with the growing discourse interrogating the “parental rights” movement and racially regressive legislation. Employing a case study analysis of social movement activism and education policy legislation from 2018–2023 in Florida, it aims to provoke critical praxis emanating from essential inquiry— what is the …


Rights Violations As Punishment, Kate Weisburd Jan 2023

Rights Violations As Punishment, Kate Weisburd

Faculty Scholarship

Is punishment generally exempt from the Constitution? That is, can the deprivation of basic constitutional rights—such as the rights to marry, bear children, worship, consult a lawyer, and protest—be imposed as direct punishment for a crime and in lieu of prison, so long as such intrusions are not “cruel and unusual” under the Eighth Amendment? On one hand, such state intrusion on fundamental rights would seem unconstitutional. On the other hand, such intrusions are often less harsh than the restriction of rights inherent in prison. If a judge can sentence someone to life in prison, how can a judge not …

Can Tourism Market Diversification Mitigate The Adverse Effects Of A Blockade On Tourism? Evidence From Qatar, Ghialy Yap, Shrabani Saha, Nelson O. Ndubisi, Saif S. Alsowaidi, Ali S. Saleh

Research outputs 2022 to 2026

This study examines the effects of an unfavorable political event or environmental hostility, namely, a blockade affecting international tourist inflows, and how tourism market diversification (TMD) could mitigate the adverse effects in the case of Qatar. To quantify these effects, we adopted a standard tourism-demand model and augmented it with a Herfindahl index (HI) for the geographical diversification of tourism exports, a dummy variable for the blockade, and an interaction variable. We further analyzed the tourist inflows from various regions using regional dummies and their interaction terms to capture the different impacts of the blockade on Qatar’s inbound tourists from …

Public Procurement For Innovation Through Supplier Firms' Sustainability Lens: A Systematic Review And Research Agenda, Peter Adjei-Bamfo, Hadrian Geri Djajadikerta, Ferry Jie, Kerry Brown, Reza Kiani Mavi Jan 2023

Public Procurement For Innovation Through Supplier Firms' Sustainability Lens: A Systematic Review And Research Agenda, Peter Adjei-Bamfo, Hadrian Geri Djajadikerta, Ferry Jie, Kerry Brown, Reza Kiani Mavi

Research outputs 2022 to 2026

Public sector purchasing processes are gaining increasing prominence as a demand-side innovation tool for addressing national sustainability challenges. Accordingly, there has been growing research attention to this topic. Prior studies suggest three key rationales that underlie the use of public sector procurement to drive innovation: (i) the buyer–user rationale (for creating new needs); (ii) the market/system failure rationale (for improving suppliers' capacity to innovate); and (iii) the public services rationale (for improving public services). However, operational activities at the upstream supply chain affecting the sustainable innovation capacities of supplier firms appear to be under-researched in the public procurement for innovation …

Powering Single-Cell Genomics To Unravel Circulating Tumour Cell Subpopulations In Non-Small Cell Lung Cancer Patients, Emmanuel Acheampong, Michael Morici, Afaf Abed, Samantha Bowyer, Du-Bois Asante, Weitao Lin, Michael Millward, Elin S. Gray, Aaron Beasley

Research outputs 2022 to 2026

Background

Circulating tumour cells (CTCs) are attractive “liquid biopsy” candidates that could provide insights into the different phenotypes of tumours present within a patient. The epithelial-to-mesenchymal transition (EMT) of CTCs is considered a critical step in tumour metastasis; however, it may confound traditional epithelial feature-based CTC isolation and detection. We applied single-cell copy number alteration (CNA) analysis for the identification of genomic alterations to confirm the neoplastic nature of circulating cells with only mesenchymal phenotypes.

Methods

We isolated CTCs from blood samples collected from 46 NSCLC patients using the Parsortix system. Enriched cells were subjected to immunofluorescent staining for CTC …

Selexipag, a selective prostacyclin receptor agonist, is approved for treating pulmonary arterial hypertension in WHO Group 1 adult patients. Compared to parenteral prostacyclin formulations, selexipag offers a significant improvement in patient’s and caregiver’s quality of life because of its oral formulation, frequency of administration, and mechanism of action. Although experience in the pediatric population is limited and selexipag is not FDA-approved for use in the pediatric pulmonary hypertension population, many US pediatric centers are expanding the use of this therapy to this younger population. We report our institution's experience in the use of selexipag to treat pulmonary hypertension in children …

Faculty, Staff and Students Publications

The incidence of type 2 diabetes in children is rising and carries a worse prognosis than in adults. The influence of sex on pediatric type 2 diabetes outcomes has not been well investigated. We studied 715 youth with type 2 diabetes diagnosed at a median age of 13.7 years and compared sex differences in demographic, clinical, and laboratory characteristics within the first year of diagnosis. Females diagnosed with type 2 diabetes were younger and at a higher stage of pubertal development than males, yet presented with lower A1Cs, a lower prevalence of diabetic ketoacidosis, and higher HDL cholesterol levels.

BACKGROUND: Pediatric Type 2 diabetes (T2D) is highly heterogeneous. Previous reports on adult-onset diabetes demonstrated the existence of diabetes clusters. Therefore, we set out to identify unique diabetes subgroups with distinct characteristics among youth with T2D using commonly available demographic, clinical, and biochemical data.

METHODS: We performed data-driven cluster analysis (K-prototypes clustering) to characterize diabetes subtypes in pediatrics using a dataset with 722 children and adolescents with autoantibody-negative T2D. The six variables included in our analysis were sex, race/ethnicity, age, BMI

RESULTS: We identified five distinct clusters of pediatric T2D, with different features, treatment regimens and risk of diabetes complications: …


Cholestasis Impairs Gut Microbiota Development And Bile Salt Hydrolase Activity In Preterm Neonates, Lauren E Lynch, Amy B Hair, Krishnakant G Soni, Heeju Yang, Laura A Gollins, Monica Narvaez-Rivas, Kenneth D R Setchell, Geoffrey A Preidis Jan 2023

Cholestasis Impairs Gut Microbiota Development And Bile Salt Hydrolase Activity In Preterm Neonates, Lauren E Lynch, Amy B Hair, Krishnakant G Soni, Heeju Yang, Laura A Gollins, Monica Narvaez-Rivas, Kenneth D R Setchell, Geoffrey A Preidis

Faculty, Staff and Students Publications

Cholestasis refers to impaired bile flow from the liver to the intestine. In neonates, cholestasis causes poor growth and may progress to liver failure and death. Normal bile flow requires an intact liver-gut-microbiome axis, whereby liver-derived primary bile acids are transformed into secondary bile acids. Microbial bile salt hydrolase (BSH) enzymes are responsible for the first step, deconjugating glycine- and taurine-conjugated primary bile acids. Cholestatic neonates often are treated with the potent choleretic bile acid ursodeoxycholic acid (UDCA), although interactions between UDCA, gut microbes, and other bile acids are poorly understood. To gain insight into how the liver-gut-microbiome axis develops …

INTRODUCTION: Preterm infants have increased risk of impaired neurodevelopment to which reduced systemic levels of insulin-like growth factor 1 (IGF-1) in the weeks after birth may play a role. Hence, we hypothesized that postnatal IGF-1 supplementation would improve brain development in preterm pigs, used as a model for preterm infants.

METHODS: Preterm pigs delivered by cesarean section received recombinant human IGF-1/IGF binding protein-3 complex (rhIGF-1/rhIGFBP-3, 2.25 mg/kg/day) or vehicle from birth to postnatal day 19. Motor function and cognition were assessed by monitoring of in-cage and open field activities, balance beam test, gait parameters, novel object recognition and operant conditioning …

To date, nutritional epidemiology has relied heavily on relatively weak methods including simple observational designs and substandard measurements. Despite low internal validity and other sources of bias, claims of causality are made commonly in this literature. Nutritional epidemiology investigations can be improved through greater scientific rigor and adherence to scientific reporting commensurate with research methods used. Some commentators advocate jettisoning nutritional epidemiology entirely, perhaps believing improvements are impossible. Still others support only normative refinements. But neither abolition nor minor tweaks are appropriate. Nutritional epidemiology, in its present state, offers utility, yet also needs marked, reformational renovation. Changing the status quo …
