Bursting The Auto Loan Bubble In The Wake Of Covid-19, Pamela Foohey

Articles

Before the COVID-19 pandemic, auto loans outstanding in the United States had soared to record highs. The boom in lending spanned new and used cars and traditional and subprime loans. With loan delinquencies also hitting new highs almost every quarter, predictions that the auto lending market could burst soon abounded. When the economy came to a grinding halt and unemployment skyrocketed in the wake of the pandemic, auto lenders knew they were facing a crisis. Throughout 2020, auto lenders granted more payment forbearances to consumers, while slashing interest rates on new loans. Auto manufacturers similarly made promises to buyers, such …

An Electrochemical Evaluation Of Novel Ferrocene Derivatives For Glutamate And Liver Biomarker Biosensing, Geok Hong Soon, Mary Deasy, Eithne Dempsey

Articles

Here, we present an evaluation of two new monosubstituted ferrocene (Fc) derivatives, 3-(1H-pyrrol-1-yl)propanamidoferrocene and 1-hydroxy-2-[2-(thiophen-3-yl)-ethylamino]ethylferrocene, as glutamate oxidase mediators, together with their preparation and characterisation. Taking into consideration the influence of the electronic effects of substituents on the redox potentials of the Fc species, two candidates with pyrrole or thiophene moieties were proposed for investigation. Film studies involved potential sweeping in the presence of pyrrole or 3,4-ethylenedioxythiophene monomers resulting in stable electroactive films with % signal loss upon cycling ranging from 1 to 7.82% and surface coverage (Γ) 0.47–1.15 × 10−9 mol/cm2 for films formed under optimal conditions. Construction of …

1d Conditional Generative Adversarial Network For Spectrum-To-Spectrum Translation Of Simulated Chemical Reflectance Signatures, Cara Murphy, John Kerekes

Articles

The classification of trace chemical residues through active spectroscopic sensing is challenging due to the lack of physics-based models that can accurately predict spectra. To overcome this challenge, we leveraged the field of domain adaptation to translate data from the simulated to the measured domain for training a classifier. We developed the first 1D conditional generative adversarial network (GAN) to perform spectrum-to-spectrum translation of reflectance signatures. We applied the 1D conditional GAN to a library of simulated spectra and quantified the improvement in classification accuracy on real data using the translated spectra for training the classifier. Using the GAN-translated library, …

(Re)Framing Race In Civil Rights Lawyering, Anthony V. Alfieri, Angela Onwuachi-Willig

Articles

This Review examines the significance of Henry Louis Gates, Jr.'s new book, Stony the Road: Reconstruction, White Supremacy, and the Rise of Jim Crow, for the study of racism in our nation's legal system and for the regulation of race in the legal profession, especially in the everyday labor of civil-rights and poverty lawyers, prosecutors, and public defenders. Surprisingly, few have explored the relevance of the racial narratives distilled by Gates in Stony the Roa - the images, stereotypes, and tropes that Whites constructed of Blacks to deepen and ensure the life and legacy of white supremacy-to the practice …

Articles

This Article explores how international human rights norms and procedures can serve as a powerful tool in addressing injustice in the United States context, using work addressing the criminalization of homelessness as a case study. Moreover, it explores how civil and political rights and negative obligations by the government can serve as an entry point for asserting a more robust understanding of rights that includes social and economic rights and affirmative obligations by government. The Article documents and analyzes original work led by the National Homelessness Law Center and other pioneering advocates, reflecting on lessons learned and next steps to …

E-Cigarettes And Smoking In Irish Teens: A Logistic Regression Analysis Of Current (Past 30-Day) Use Of E-Cigarettes, Joan Hanafin, Salome Sunday, Luke Clancy

Articles

Aim

Electronic cigarette (e-cigarette) use among Irish teenagers has risen significantly. In 2019, prevalence of current use (last 30 days) among 15–17-year-olds was 17.3%. We examine social determinants of adolescent e-cigarette current use.

Subject and methods

A stratified random sample of 50 schools in Ireland was surveyed in 2019, part of the European School Survey Project on Alcohol and other Drugs (ESPAD), with 3495 students aged 15, 16, and 17. Bivariate and multivariable logistic regression [providing adjusted odds ratios (AORs)] analyses were performed using Stata version 16.

Current e-cigarette users were more likely to be male (AOR = 0.55, …

Deal Protection Devices, Albert H. Choi

Articles

In mergers and acquisitions transactions, a buyer and a seller will often agree to contractual mechanisms (deal protection devices) to deter third parties from jumping the deal and to compensate a disappointed buyer. With the help of auction theory, this Article analyzes various deal protection devices, while focusing on the two most commonly used mechanisms: match rights and target termination fees. A match right gives the buyer a right to “match” a third party’s offer so as to prevent the third party from snatching the target away, while a termination fee compensates the buyer when a third party acquires the …

Β-Glucosidase From Streptomyces Griseus: Ester Hydrolysis And Alkyl Glucoside Synthesis In The Presence Of Deep Eutectic Solvents, Albert Uhoraningoga, Gemma K. Kinsella, Gary T. Henehan, Barry J. Ryan

Articles

Deep Eutectic Solvents (DES) are ionic liquid analogs that have attracted considerable attention as green solvents for biocatalytic transformations. The use of DES as part of a ‘solvent engineering’ approach to enhance enzyme stability holds great promise since they are biodegradeable, relatively inexpensive and environmentally safe media for enzyme reactions. However, the behaviour of specific enzymes in such solvents is complex; some enzymes are inhibited in DES, while others appear to be activated.

Glucosidases are among the most widely used enzymes for commercial chemoenzymatic synthesis. In particular, their application in the synthesis of biodegradable alkyl glucosides by reverse hydrolysis is …

Metatheme Analysis: A Qualitative Method For Cross-Cultural Research, Amber Wutich, Melissa Beresford, Cindi Sturtzsreetharan, Alexandra Brewis, Sarah Trainer, Jessica Hardin

Articles

In recent years, there has been a florescence of cross-cultural research using ethnographic and qualitative data. This cutting-edge work confronts a range of significant methodological challenges, but has not yet addressed how thematic analysis can be modified for use in cross-cultural ethnography. Thematic analysis is widely used in qualitative and mixed-methods research, yet is not currently well-adapted to cross-cultural ethnographic designs. We build on existing thematic analysis techniques to discuss a method to inductively identify metathemes (defined here as themes that occur across cultures). Identifying metathemes in crosscultural research is important because metathemes enable researchers to use systematic comparisons to …

Temperature-Sensitive Holograms With Switchable Memory, Muhammad Irfan Dr, Suzanne Martin Dr, Izabela Naydenova Prof

Articles

Abstract

Herein, the dynamics and reversibility of temperature-induced changes in volume phase holographic gratings (VPHGs) recorded in the low-toxicity self-processing photopolymer poly(N-isopropyl acrylamide) (poly-NIPA) are reported on. Transmission and reflection gratings are exposed to temperatures ranging 8–60 °C to study the effect of temperature on their properties. First, the role of the photopolymer chemical composition is investigated by comparing layers containing NIPA with those containing acrylamide (AA) and measuring the normalized diffraction efficiency (DE) at 60 °C; higher thermal sensitivity is observed for poly-NIPA gratings (24% drop) versus low sensitivity for AA gratings (2% increase). The impact of …

Why Parents Chose To Send Their Children To Irish-Medium Immersion Preschools: Learning From Parental Choice Strategies In Celtic Countries, Maire Mhic Mhathuna, Fiona Nic Fhionnlaoich

Articles

This study investigated the reasons Irish parents chose to send their children to Irish-medium preschools settings over other forms of early childhood education. The international literature on parental decision making regarding childcare and relevant studies on immersion education in Celtic countries were reviewed. A parental questionnaire, informed by this literature, was distributed through selected immersion settings in Ireland. Social and cognitive development were the main reasons parents cited in regard to early childhood education and an interest in the Irish language and bilingualism along with the good reputation of the immersion preschool were the reasons they chose immersion preschooling. Comparisons …

3D cell culture is a process used to grow cells in vitro to mimic an in vivo environment. 3D cell models are very useful for understanding disease mechanisms and exploring drug therapeutics. 3D cultures can be grown from cells taken from cancer organoids in patients. Once grown, they can be used to screen for small molecule drugs or they can be genetically modified in order to analyse disease pathways or predict the toxicity or efficacy of a drug treatment. These cultures decrease the need to use animals in research and provides more reliable results as it uses human physiology. This …

U-251mg Spheroid Generation Using Hanging Drop Method Protocol, Lara Carroll, Brijesh K. Tiwari, James F. Curtin, Janith Wanigasekara

Articles

The use of 3D cell culture has been a major step in developing cellular models that can mimic physiological tissues. Traditional 2D cell cultures are often unable to accurately represent the cellular functions and responses that are present in tissues, as a result, research findings based on 2D cultures tend to be skewed with limited predictive capability. 3D cell cultures can be grown from cells obtained from cancer organoids in patients. These models are useful for understanding disease mechanisms and exploring drug therapeutics in areas such as toxicity and efficacy. In order to gather more physiologically relevant data, a variety …

Finding The Needle In A Haystack: On The Automatic Identification Of Accessibility User Reviews, Eman Abdullah Alomar, Wajdi Aljedaani, Murtaza Tamjeed, Mohamed Wiem Mkaouer, Yasime Elglaly

Articles

In recent years, mobile accessibility has become an important trend with the goal of allowing all users the possibility of using any app without many limitations. User reviews include insights that are useful for app evolution. However, with the increase in the amount of received reviews, manually analyzing them is tedious and time-consuming, especially when searching for accessibility reviews. The goal of this paper is to support the automated identification of accessibility in user reviews, to help technology professionals in prioritizing their handling, and thus, creating more inclusive apps. Particularly, we design a model that takes as input accessibility user …

Going Rogue: The Supreme Court's Newfound Hostility To Policy-Based Bivens Claims, Joanna C. Schwartz, Alexander A. Reinert, James E. Pfander

Articles

In Ziglar v. Abbasi, 137 S. Ct. 1843 (2017), the Supreme Court held that a proposed Bivens remedy was subject to an exacting special factors analysis when the claim arises in a “new context.” In Ziglar itself, the Court found the context of the plaintiffs’ claims to be “new” because, in the Court’s view, they challenged “large-scale policy decisions concerning the conditions of confinement imposed on hundreds of prisoners.” Bivens claims for damages caused by unconstitutional policies, the Court suggested, were inappropriate.

This Essay critically examines the Ziglar Court’s newfound hostility to policy-based Bivens claims. We show that an …

Physics-Guided Neural Network For Predicting Chemical Signatures, Cara Murphy, John Kerekes

Articles

Achieving high classification accuracy on trace chemical residues in active spectroscopic sensing is challenging due to the limited amount of training data available to the classifier. Such classifiers often rely on physics-based models for generating training data though these models are not always accurate when compared to measured data. To overcome this challenge, we developed a physics-guided neural network (PGNN) for predicting chemical reflectance for a set of parameterized inputs that is more accurate than the state-of-the-art physics-based signature model for chemical residues. After training the PGNN, we use it to generate a library of predicted spectra for training a …

Protecting Culturally Identifiable Fashion: What Role For Gis?, J. Janewa Osei-Tutu

Articles

Geographical indications are a type of intellectual property right that can be used to protect a source indicator when some quality, characteristic, or reputation of a good is attributable to its geographic origin. To the extent that geographic location and culture overlap, geographical indications could be described as a form of cultural protection. Italy, which is known for both its food and fashion, has geographical indications for a range of items, such as extra virgin olive oils, pastas, and wines. Can geographical indications protect other aspects of culture, such as fashion? For example, the famous Italian designer, Valentino, received both …

Dead Men (And Women) Should Tell Tales: Narrative, Intent, And The Construction Of Wills, Karen J. Sneddon

Articles

The will is one of the most personal legal documents that an individual may ever create. The will is written in first person, present tense. Yet most wills reveal little of the person, the personality, or the personal. The inclusion of the testator’s relationships with people, entities, and property does little to convey the testator’s wishes, hopes, or fears. Some may assert that as a formal legal document, the will should be impersonal and be built using standardized, formulaic phrasing. Not only does such position overstate the accuracy of standardized, formulaic phrasing, but such position also ignores the foundational principle …

Digital Gatekeepers, Thomas E. Kadri

Articles

If in William Blackstone's time we might have thought of a person's home as their castle, in Mark Zuckerberg's time we might say that their website is too.  Under cyber-trespass laws like the Computer Fraud and Abuse Act, courts have treated online platforms as digital gatekeepers--as property owners that may permit and restrict access to websites much like landowners may do with private land in the real world. If platforms withhold their consent through words or inference, cyber-trespass laws let them enforce their preferences about who may access their services and gather information from the internet. Concerned about reputations and …

Articles

The author taught many years of color reproduction-related courses to college students in print media and graphic communication programs. He used to think that hands-on lab assignment was only possible in-person in laboratory settings. His recent online teaching experiences proved him wrong. This document describes a lab assignment, Using ColorThink, in an online course, administered by Wuhan University, in the summer of 2020. Due to the coronavirus pandemic, no one was on campus. All eleven students were spread out across many provinces in China. As an adjunct instructor, located in North America, the author was able to connect with his …

The Mdl Revolution And Consumer Legal Funding, Ronen Avraham, Lynn A. Baker, Anthony J. Sebok

Articles

Third-party consumer legal funding, where financial companies advance money on a nonrecourse basis to assist individual plaintiffs with living expenses, is an increasingly popular and controversial part of American litigation. And consumers with mass tort claims pending in Multi-District Litigations (MDLs) constitute the fastest growing sector of those seeking assistance from this billion-dollar funding industry. Policy makers, mass tort plaintiffs' lawyers, and scholars have increasingly raised concerns about exorbitant interest rates and have called for regulations to protect vulnerable consumers from “predatory lending.” To date, however, the policy debate has largely relied on anecdotes and speculation because flinders have not …

Using Random Assignment To Measure Court Accessibility For Low-Income Divorce Seekers, James D. Greiner, Ellen L. Degnan, Thomas Ferriss, Roseanna Sommers

Articles

We conducted a field experiment in which 311 low-income individuals seeking a divorce were randomly assigned to receive access to a pro bono lawyer (versus minimal help) to assist with filing for divorce. Examining court records, we found that assignment to an attorney made a large difference in whether participants filed for and obtained a divorce. Three years after randomization, 46% of the treated group had terminated their marriages in the proper legal venue, compared to 9% of the control group. Among “compliers”—participants who obtained representation only if assigned to receive it—those with lawyers were far more likely to file …

Diagnostics Of A Large Volume Pin-To-Plate Atmospheric Plasma Source For The Study Of Plasma Species Interactions With Cancer Cell Cultures, Laurence Scally, Chaitanya Sarangapani, Brijesh Tiwari, Renee Malone, Hugh Byrne, James Curtin, P.J. Cullen

Articles

A large gap pin-to-plate, atmospheric pressure plasma reactor is demonstrated as means of in vitro study of plasma species interactions with cell cultures. By employing optical emission and optical absorption spectroscopy, we report that the pin-to-pate plasma array had an optimal discharge frequency for cell death of 1000 Hz in ambient air for the target cancer cell line; human glioblastoma multiform (U-251MG). The detected plasma chemistry contained reactive oxygen and nitrogen species including OH, N₂, N₂⁺, and O₃. We show that, by varying the plasma discharge frequency, the plasma chemistry can be tailored …

The Norms Of Algorithmic Credit Scoring, Nikita Aggarwal

Articles

This article examines the growth of algorithmic credit scoring and its implications for the regulation of consumer credit markets in the UK. It constructs a frame of analysis for the regulation of algorithmic credit scoring, bound by the core norms underpinning UK consumer credit and data protection regulation: allocative efficiency, distributional fairness and consumer privacy (as autonomy). Examining the normative trade-offs that arise within this frame, the article argues that existing data protection and consumer credit frameworks do not achieve an appropriate normative balance in the regulation of algorithmic credit scoring. In particular, the growing reliance on consumers' personal data …

The Human Capital Management Movement In U.S. Corporate Law, George S. Georgiev

Articles

Corporations cannot exist without workers, yet workers are not part of the formal or informal governance structures established by U.S. corporate law. Commentators and policymakers have bemoaned this state of affairs for decades, to little avail. Since the mid-2010s, however, a concept related to workers, human capital management (HCM), has become an increasingly prominent part of U.S. corporate governance. HCM is premised on the notion that workers can be viewed as "assets" and ought to be managed just as carefully as firms manage physical and capital assets. In practice, HCM is an expansive concept that has been used to refer …
