Don't Interfere With My Rights! Employee Rights Violation And The Cost Of Bank Loans, Amirhossein Fard, Ibrahim Siraj, Bin Wang

Finance Faculty Research and Publications

We study the relationship between the cost of bank loans and the charges filed to the National Labor Relations Board (NLRB) due to managerial interference in employee rights. Loans issued after the filing of the allegations are associated with significantly higher loan spreads than loans initiated before the filing of allegations. Strong allegations that result in withdrawal with adjustments or compliance tend to positively affect the loan pricing. Further, interfering firms tend to experience higher default risks in the years following the filing of charges. Our paper is the first in the literature to show the impact of violation of …

Dysregulation Of Complement System In Neuropsychiatric Disorders: A Mini Review, Danny Perez Sierra, Ashutosh Tripathi, Anilkumar Pillai

Faculty, Staff and Student Publications

Complement system is one of the most important defense mechanisms of the innate immune system. In addition to their roles in immune regulation, complement proteins are also involved in neurodevelopment and adult brain plasticity. Complement dysregulation has been shown in neurodevelopmental disorders including schizophrenia and autism spectrum disorder as well as in mood disorders. A number of clinical as well as genetic studies suggest the role of complement proteins in the cortical thinning and excessive synaptic pruning frequently associated with schizophrenia. The changes in complement proteins are also associated with the pathophysiology of autism spectrum disorder, major depressive disorder and …

Which Children Are Frequently Victimized In Us Elementary Schools? Population-Based Estimates, Paul L Morgan, Adrienne D Woods, Yangyang Wang, George Farkas, Yoonkyung Oh, Marianne M Hillemeier, Cynthia Mitchell

Faculty, Staff and Student Publications

We analyzed a population-based cohort of 11,780 U.S. kindergarten children to identify risk and protective factors predictive of frequent verbal, social, reputational, and/or physical bullying victimization during the upper elementary grades. We also stratified the analyses by biological sex. Both girls and boys displaying kindergarten externalizing problem behaviors were at consistently higher risk of frequent victimization during 3rd-5th grade (for the combined sample of boys and girls, verbal odds ratio [OR] = 1.82, social OR = 1.60, reputational OR = 1.85, physical OR = 1.67, total OR = 1.93). Hispanic children relative to non-Hispanic White children and those from higher …

Predictors For Outcomes Of Noninvasive, Individualized Transcranial Magnetic Neuromodulation In Multiple Sclerosis Women With Neurogenic Voiding Dysfunction, Yongchang Jang, Khue Tran, Zhaoyue Shi, Karmonik Christof, Darshil Choksi, Betsy H Salazar, John A Lincoln, Rose Khavari

Faculty, Staff and Student Publications

Purpose:

Multiple sclerosis (MS) is a multifocal demyelinating disease that affects the central nervous system (CNS) and commonly leads to neurogenic lower urinary tract dysfunction (NLUTD). Proper storage and release of urine relies on synchronized activity of the LUT, which is meticulously regulated by supraspinal circuits, making it vulnerable to diseases such as MS. NLUTD, characterized by voiding dysfunction (VD), storage issues, or a combination of both is a common occurrence in MS. Unfortunately, there are limited treatment options for NLUTD, making the search for alternative treatments such as transcranial rotating permanent magnet stimulation (TRPMS) of utmost importance. To assess …

Choreographing Neutrality: Dance In Cambodia’S Cold War Diplomacy In Asia, 1953-1970, Darlene Machell Espena

Research Collection School of Social Sciences

This article examines the role of dance in Cambodia’s Cold War diplomacy in Asia from 1953 up until the establishment of the Khmer Republic in 1970. It explores how Sihanouk leveraged Cambodian dances to enact Cambodia’s neutral stance during the Cold War and forge cordial relations with other Asian states. Through an examination of the myriad of dance performances of the Royal Ballet and other Khmer dance troupes within the context of Cambodia’s diplomatic relations in Asia, this paper demonstrates how dance afforded a space for Inter-Asia referencing amidst the Cold War tension in the region. Premised on an interdisciplinary …

Political Signalling And Emissions Trading Schemes In China: Insights From Guangdong Province, Chen Xiang, Terry Van Gevelt

Research Collection College of Integrative Studies

China's approach to environmental regulation relies heavily on campaign-style enforcement and blunt-force regulation. While considered effective in the short run, this approach is often inefficient and generates unintended regulatory outcomes in the longer run. At the same time, China continues to experiment with the use of market-based approaches that are theoretically more efficient and have the potential to facilitate sustained reductions in carbon emissions. Arguably the most high-profile example is the Guangdong Emissions Trading Scheme (ETS), which was launched in 2013 as a national pilot scheme. We construct a synthetic control of Guangdong and analyse 51,076 party-led newspaper reports to …

The Effect Of Executive Function On The Development Of Chronic Pain: A Prospective Longitudinal Study, Wee Qin Ng, Andree Hartanto

Research Collection School of Social Sciences

Increasing evidence suggests a close association between chronic pain and executive function, a set of cognitive processes necessary for goal-directed behaviors. However, there is a dearth of longitudinal studies examining the predictive effect of executive function on the development of chronic pain. Drawing on the cyclical model of executive function and health, we sought to examine how executive function, measured at baseline, may predict chronic pain etiology approximately 9 years later. Using a large-scale dataset of midlife adults (N = 1553) from the MIDUS 2 and 3 (Midlife Development in the United States) studies, we employed multivariate logistic regression to …

Understanding The Impact Of Covid-19 Pandemic On Teleworkers' Experiences Of Perceived Threat And Professional Isolation: The Moderating Role Of Friendship, Xinyu (Judy) Hu, Mahesh Subramony

Arts & Sciences Faculty Publications

Drawing from conservation of resource theory and the social support resource theory, this study examines how the severity of an exogenous disruptive event – the COVID-19 pandemic – in one's community influences teleworkers' well-being outcomes indirectly through their perceptions of pandemic-related threat and experience of professional isolation, as well as the buffering effect of friendship on these relationships. Utilizing time-lagged data from participants of a two-wave survey panel (N = 351) and objective data of COVID-19 severity from counties around the United States, we found that perceived threat, but not professional isolation, mediated the negative effect of proportion of confirmed …

Patient Identification Of Diagnostic Safety Blindspots And Participation In “Good Catches” Through Shared Visit Notes, Sigall K Bell, Fabienne Bourgeois, Joe Dong, Alex Gillespie, Long H Ngo, Tom W Reader, Eric J Thomas, Catherine M Desroches

Faculty, Staff and Student Publications

Policy Points Patients and families can identify clinically relevant errors, including "blindspots"-safety hazards that are difficult for clinicians or organizations to see. Health information transparency, including patient access to electronic visit notes, now federally mandated in the US and the subject of policy debate worldwide, creates a new opportunity to engage patients in diagnostic safety. However, not all patients access notes. Patient identification of blindspots in their notes underscores the need to systematically and equitably engage willing patients in safety, promote patient "good catches," and establish routine systems for patient feedback to help avoid preventable diagnostic errors and delays.

Understanding Superintendents’ Approaches To The Implementation Of District Systems In The Context Of A Crisis, Jarad C. Munroe

Educational Leadership & Workforce Development Theses & Dissertations

The COVID-19 pandemic presented a crisis that district superintendents and their leadership teams had not before experienced. In a matter of weeks, school systems needed to transition away from a traditional learning model, where teaching and learning occurred in a physical classroom, to a virtual learning environment. School districts were provided little time to strategically develop a model to transform their systems to continue to meet student learning goals. The districts were still expected to fully operate, while prioritizing the acquisition of resources that could provide the means for a deliberate shift to establish a virtual learning system. This qualitative …

Destroying The Myth Of The Monolith: A Historical Observation Of The Black Conservative From Then To Now, Jessica Reese

Honors Theses

Although it is not often reflected at the ballot box, Black America has a wide variety of political thought processes mostly rooted in socially conservative backgrounds. There has been a false, and frankly disrespectful, narrative that all Black Americans affirm to the same political ideology, vote in similar patterns, and align with the same political party. The uprising of Black Americans, specifically within the young electorate, who hold political conservative thought processes is the inspiration of this thesis. Starting with the 1780s and progressing through the 2020s, this thesis will observe the historical shifts and expansion of Black conservatism in …

Generating Honeyword Based On A Proposed Bees Algorithm, Yasser A. Yasser, Ahmed T., Wasim Alhamdani

Iraqi Journal of Computers, Communications, Control and Systems Engineering

Honeywords are fake passwords that are typically companions to the real password “sugarword.” The honeyword technique is a password cracking detection technique that works effectively to improve the security of hashed passwords by making password cracking simpler to detect. The password database will contain many honeywords for each user in the system. A silent alarm will trigger, indicating that the password database has been compromised if the hacker signs in using a honeyword. The honeychecker is a separate server in charge of recognizing the real password and raising the silent alarm. Many honeyword creation techniques have been presented previously. They …

Disruption Of Marine Habitats By Artificial Light At Night From Global Coastal Megacities, T. W. Davies, T. J. Smyth, A. E. Wright, A. Edwards-Jones, A Queiros, O. Rendon, S. Tidau, D. Mckee

School of Biological and Marine Sciences

Half of globally significant megacities are situated near the coast, exposing urban marine ecosystems to multiple stressors such as waste-water discharge containing a host of organic and inorganic pollutants, air and noise pollution. In addition to these well recognized sources, artificial light at night (ALAN) pollution is inseparable from cities but poorly quantified in marine ecosystems to date. We have developed a time- and wavelength-resolving hydrological optical model that includes solar (daylight and twilight components), lunar and ALAN source terms and propagates these spectrally through a tidally varying water column using Beer’s Law. Our model shows that for 8 globally …

The Role Of Lipocalin 2 In Type 1 Diabetic Osteopathy, Rawan Mahmoud Bdair

Theses

Lipocalin 2 (LCN2), also known as neutrophil gelatinase-associated lipocalin (NGAL), plays an important role in the innate immune response and functions as a growth factor. The role of LCN2 as an anti-inflammatory protein and its function in bone metabolism is poorly understood. It is hypothesized that the administration of Lipocalin-2 in diabetic and non-diabetic rats will positively improve the bone microstructure. This study investigated the effect of lipocalin2 on bone metabolism in type 1 diabetic osteopathy (T1DO). Three-month-old male Wistar rats (n=24) were obtained from the animal house facility at United Arab Emirates University (UAEU) for this study. All animal …

Medical Harm Without Negligence, Valerie Gutmann Koch

Fordham Law Review

In December 2019, seven women from one family underwent highly invasive surgeries based on genetic test results that indicated that each were at significant risk of developing cancer by age seventy. Subsequently, after procedures that (among other things) permanently scarred and disfigured their bodies and ended their chances of having biological children, they learned that their particular mutation was not, in fact, pathogenic.

This Article focuses on a previously under-recognized problem: what happens when a patient’s previously classified pathogenic variant is downgraded to uncertain (or even benign) status? Intuitively, it might seem that the genetic testing company, the surgeons, or …

Within A City's Limits: A Local Government's Power To Hold Police Officers Accountable, Josselin Aldana

Fordham Law Review

When a person’s constitutional rights are violated by a public official, such as a police officer, who acts under color of law, the official can invoke a qualified immunity defense that immunizes the official unless it is clearly established that such action is unlawful. Over the years, the qualified immunity doctrine has developed into a shield that makes it difficult for aggrieved individuals to recover when they are harmed. As a result of nationwide focus on police brutality, four states—Colorado, Connecticut, Massachusetts, and New Mexico—have modified the use of qualified immunity as a defense in state courts for individuals harmed …

The Prison Mailbox Rule: Can Represented Incarcerated Litigants Benefit?, Nico Corti

Fordham Law Review

In 1988, the U.S. Supreme Court created the “Prison Mailbox Rule,” which assesses the timeliness of incarcerated litigants’ filings based on the day they hand them to prison authorities. The rule reduces the structural barriers to filing while imprisoned. Although Houston v. Lack highlighted the unique challenges that pro se incarcerated litigants face, the Prison Mailbox Rule’s subsequent federal codifications did not limit its benefits to pro se litigants, despite purportedly “reflecting” the Houston decision. Federal circuit courts of appeal today are split on whether represented people in prison can benefit from the Prison Mailbox Rule, leaving both litigants and …
