Studying The Photodegradation Of Congo Red Dye From Aqueous Solutions Using Bimetallic Au–Pd/Tio2 Photocatalyst, Souad A. Mousa, Sanaa Tareq, Eman A. Muhammed

Baghdad Science Journal

In this study, the photodegradation of Congo red dye (CR) in aqueous solution was investigated using Au-Pd/TiO2 as photocatalyst. The concentration of dye, dosage of photocatalyst, amount of H2O2, pH of the medium and temperature were examined to find the optimum values of these parameters. It has been found that 28 ppm was the best dye concentration. The optimum amount of photocatalyst was 0.09 g/75 mL of dye solution when the degradation percent was ~ 96 % after irradiation time of 12 hours, while the best amount of hydrogen peroxide was 7μl/75 mL of dye solution at degradation percent ~97 …

Arbitrating Copyright Disputes In Egypt, Islam Mohamed

Maurer Theses and Dissertations

Egypt is witnessing increasing difficulty in implementing and practicing protectionist policies for intellectual property rights, which includes copyright as a fundamental element. Since the Egyptian judicial system is exclusively concerned with adjudicating all disputes, it has become increasingly burdened in recent decades due to this monopoly. As a result, the Egyptian judiciary is witnessing a significant slowdown in resolving conflicts and procedural obstacles which delay the restitution of Intellectual property rights to its owners. Thus, we believe that applying arbitration will contribute to resolving copyright disputes in advance on one hand and will encourage an attractive climate in such matters …

Murky Materiality & Scattered Standards: In Favor Of A More Uniform System Of Sst Disclosure Requirements, Megan Ganley

Fordham Law Review

The Securities and Exchange Commission (SEC) requires corporations to disclose their business in or with state sponsors of terrorism (SSTs). The SEC solicits these disclosures with varying standards arising under several different mechanisms. These mechanisms include the requirements of the materiality standard, the provisions of Regulation S-K, targeted inquiry in individually issued comment letters, and affirmative requirements mandated under specific legislation. Each of these mechanisms requires disclosure of slightly different information regarding SSTs with varying degrees of exactitude. This Note examines the SEC’s current SST disclosure framework, considering the benefits, as well as the criticisms, of these disclosure mandates. This …

Qui Tam And The Bank Secrecy Act: A Public-Private Enforcement Model To Improve Anti-Money Laundering Efforts, Giovanni Scarcella

Fordham Law Review

Cartels, terrorists, fraudsters, and other criminals face a problem: when they receive the proceeds from their illicit activities, how can they get this money into their bank accounts without raising regulatory eyebrows? The Bank Secrecy Act (BSA) has established a complex regulatory regime, imposing on banks the duty to assess the risks presented by their clients, to monitor the transactions they process, and to report transactions that contain indicia of money laundering and other criminal activity to the Financial Crimes Enforcement Network (FinCEN). In response, criminals utilize increasingly sophisticated means to obfuscate the origins of these transactions and disguise their …

Who Tells Their Stories?: Examining The Role, Duties, And Ethical Constraints Of The Victim’S Attorney Under Model Rule 3.6, Ksenia Matthews

Fordham Law Review

In U.S. criminal proceedings, the prosecution typically presents the victim’s story. However, as part of the victims’ rights movement, victims are striving to make their voices heard and tell their stories in their own words. Yet, despite the growing role victims occupy in criminal proceedings and the rights afforded to victims by the Crime Victims’ Rights Act and its state counterparts, victims still remain nonparties in criminal proceedings. As victims increasingly retain private lawyers to help navigate criminal proceedings and represent their interests, it is important to understand how these lawyers fall within the traditional two-party adversary system. Limited by …

Overparticipation: Designing Effective Land Use Public Processes, Anika Singh Lemar

Fordham Law Review

There are more opportunities for public participation in the planning and zoning process today than there were in the decades immediately after states adopted the first zoning enabling acts. As a result, today, public participation, dominated by nearby residents, drives most land use planning and zoning decisions. Enhanced public participation rights are often seen as an unqualified good, but there is a long history of public participation and community control cementing racial segregation, entrenching exclusion, and preventing the development of affordable housing in cities and suburbs alike. Integrating community engagement into an effective administrative process requires addressing the various ways …

Copyright’S Techno-Pessimist Creep, Xiyin Tang

Fordham Law Review

Government investigations and public scrutiny of Big Tech are at an all-time high. While current legal scholarship and government focus have centered overwhelmingly on whether and how antitrust law and § 230 of the Communications Decency Act can be revised to address platform dominance, scant attention has been paid to another, almost unseen attempt to regulate Big Tech: copyright law. The recent adoption in Europe of Article 17 of the Copyright Directive, which holds internet platforms liable for user-generated creative content unless they obtain costly content licenses, is the most direct example of such regulation—and may serve as precedent for …

“Community Guidelines”: The Legal Implications Of Workplace Conditions For Internet Content Moderators, Anna Drootin

Fordham Law Review

Content moderation is the internet’s not-so-secret, dirty little secret. Content moderators are working around the world, and around the clock, to scrub the internet of horrific content. Most moderators work for low pay and with little or no health care benefits. The content they are exposed to leaves them vulnerable to a number of different mental health issues, including post-traumatic stress disorder. Their work is often hidden from users and is de-emphasized by the technology industry. This Note explores potential solutions to the labor and employment issues inherent in content moderation work and suggests that there could be a path …

The Impact Of Covid-19 On The Thai Probation Department, Thanaphon Nunphong

Student Theses

The COVID-19 pandemic had a crucial impact on the Thai criminal justice system. While it may be true that the Department of Probation has proposed preventive and responsive measures in response to COVID-19, relatively little is known about the practical applications of these measures as well as the impact of COVID-19 on probation personnel, probationers, and parolees. The goal of this study is to explore the policies and practices of Thai probation agencies as they respond to the COVID-19 pandemic. This study surveyed probation officers in Thailand (N = 534; 60.6% Female) in March to April 2021, focusing on …

The Influence Of Demographic Information On Public Attitudes Towards Individuals Who Commit Sexual Offenses, Emily Bogdan

Student Theses

Research exploring the factors that shape public attitudes towards individuals who commit sexual offenses is needed to inform policy and reduce stigma that these individuals face as they reenter society. Prior research has explored demographic factors of those who offend and have been victimized, but few have studied how these variables may interact with one another to shape attitudes toward people who commit sexual offenses. The current study explores whether offender gender, victim gender, and victim age shape the public’s attitudes towards these individuals. Participants were presented with a vignette describing the offense and then they were asked to respond …

Support For Militant U.S. Foreign Policy: The Role Of Authoritarianism And International Xenophobia, Brandon M. Garcia

Student Theses

Right-Wing Authoritarianism (RWA) has been studied extensively in the domestic socio-political context, but its potential impact on foreign policy is still poorly understood. The current study replicated the putative two-factor model of the construct (Authoritarian Aggression/Submission and Conventionalism) and examined the associations of each factor with perceptions of overall danger to the U.S. posed by other countries and with the support for more militant U.S. foreign policy. As expected, both RWA factors correlated with self-reported levels of political conservatism (r = 0.32, r = 0.33; p < .001) Additionally, Authoritarian Aggression and Submission (but not Conventionalism) were correlated with increased perceived danger from foreign countries (r = .35; p < .001) and increased support for a more militant U.S. foreign policy (r = .25; p < .001). Participants higher in RWA were more likely to view the world as a hostile and threatening place, and in turn support more aggressive military action in response to those fears.

Let The Bots Be Bots: Why The Cfaa Must Be Clarified To Prevent The Selective Banning Of Data Collection Facilitating Private Social Media Information Monopolization, W. Connor Mcrory

Brooklyn Journal of Corporate, Financial & Commercial Law

In September 2019, the United States Court of Appeals for the Ninth Circuit granted plaintiff-startup hiQ Labs a preliminary injunction allowing it to “bot scrape” off of defendant-social networking service LinkedIn’s public profiles without triggering liability under Section 1030(a)(2)(C) of the Computer Fraud & Abuse Act (CFAA) for accessing a website “without authorization.” Differing judicial interpretations demonstrate the lack of clarity as to the legality of third-party bot scraping against the website owner’s consent, which causes irreparable harm to businesses that rely on such practices to operate, and antitrust issues when website owners like LinkedIn and Facebook can selectively ban …

When Your Apps Threaten National Security – A Review Of The Tiktok And Wechat Bans And Government Actions Under Ieepa And Firrma, Ru Hochen

Brooklyn Journal of Corporate, Financial & Commercial Law

Personal data can evolve into a national security issue. In August 2020, fears of foreign adversaries’ access to Americans’ personal data prompted President Trump to issue two executive orders that attempted to ban Chinese-owned social media applications TikTok and WeChat in the United States. In the last few years, the U.S. executive branch has acted against foreign entities that implicate national security interests via two primary tools: the presidential power under the International Economic Emergency Powers Act (IEEPA) and a foreign investment screening regime under the Foreign Investment Risk Review Modernization Act of 2018 (FIRRMA). However, the statutes were enacted …

Investigating Therapeutic Strategies To Target Metabolic Vulnerabilities Of Nsclc Tumors With Mutant Keap1 Gene, Pranavi Koppula

Dissertations and Theses (Open Access)

The metabolic vulnerability of cancers has long been envisaged as an attractive window to develop novel therapeutic strategies. Metabolic flexibility at the cellular level encompasses the efficient rerouting of anabolic and catabolic pathways in response to varying environmental stimuli to maintain cellular homeostasis and sustain proliferation. The primary objective of this study is to identify metabolic vulnerabilities bestowed by KEAP1/NRF2 signaling axis through SLC7A11. SLC7A11 is a transcriptional target of NRF2, an essential regulator of cellular anti-oxidant response. Under unstressed basal conditions, NRF2 interacts with KEAP1, a tumor suppressor gene and a substrate adaptor protein of the Cullin3-dependent ubiquitin ligase …

Modulation Of The Receptor Gating Mechanism And Allosteric Communication In Ionotropic Glutamate Receptors, Nabina Paudyal, Nabina Paudyal

Dissertations and Theses (Open Access)

Ionotropic glutamate receptors (iGluRs) found in mammalian brain are primarily known to mediate excitatory synaptic transmission crucial for learning and memory formation. The family of iGluRs consists of AMPA receptors, NMDA receptors and kainate receptors with each member having distinct physiological role. In the recent years, significant progress has been made in understanding the biophysical, and functional properties of iGluRs. The development of Cryo-EM and X-Ray crystallography techniques have further facilitated in the structural understanding of these receptors. However, the multidomain nature, large size of the protein, complex gating mechanism and inadequate knowledge regarding the conformational dynamics of the receptors …

Mutant Kras Alters Extracellular Vesicle Microrna Sorting In Pancreatic Cystic Neoplasms, Rachel L. Dittmar

Dissertations and Theses (Open Access)

Pancreatic ductal adenocarcinoma (PDAC) is among the deadliest cancers by organ site with a 5-year survival rate of just 10.8%. This is largely because most patients do not experience symptoms until the disease has already metastasized. The best hope to cure PDAC is surgery, which can only be done with a curative intent at an early stage when the disease is localized. There are no reliable circulating, body-fluid-based biomarkers to detect early stage PDAC or its precursor lesions in a timely manner for effective surgical intervention. When potential PDAC precursor lesions, such as mucinous pancreatic cysts are found, there are …

Enhancing Adoptive Cell Therapy By Augmenting Fitness And Anti-Tumor Function Of Tumor-Infiltrating Lymphocytes, Parin Shah

Dissertations and Theses (Open Access)

The success of immune checkpoint inhibitors (ICIs) has established the importance of cancer immunotherapy in solid cancers, where it has been adopted as one of the standards of care for advanced melanoma and lung cancer. It is currently being investigated to treat other solid cancers. However, a large fraction of patients do not respond to ICIs and relapse. ICI therapy offers an in vivo approach to activate tumor-specific T cells, albeit in some cases, this modality does not create a sufficiently robust anti-tumor response. Thus, ex vivo approaches employing manipulation of immune cells, such as Adoptive Cell Therapy (ACT) using …

Cross-Seeding Potential Of Misfolded Amyloid-Beta Strains On Tau Protein: Examining The Puzzle Pieces Of Alzheimer's Disease, Sara Kelley

Dissertations and Theses (Open Access)

Alzheimer’s disease (AD) is a neurodegenerative disorder that will progressively impair cognitive function. AD is the leading source of dementia, and affects one third of the senior citizens in the United States. Aging is the primary risk factor for AD and due to the expected rise in human lifespan worldwide, the occurrence rate of AD diagnosis is projected to increase. This observation is increasingly alarming when considering there is no treatment for reversal or prevention of AD yet.

AD is characterized by gross pathological hallmarks in the brain. These include the extracellular accumulation of misfolded amyloid-beta (Aβ) and the intraneuronal …

Mitochondrial Unfolded Protein Response Regulator Atf5 In Mitochondrial Targeted Therapies In Aml, Ran Zhao

Dissertations and Theses (Open Access)

Mitochondrial unfolded protein response (UPR^mt) is an adaptive transcriptional response induced by damaged proteins accumulated in mitochondria. UPR^mt signaling involves induction of mitochondrial specific chaperones and proteases such as HSP60, LonP1 and ClpP, aiding in the restoration of mitochondrial protein pool homeostasis. However, the cell-protective roles of UPR^mt in the context of mitochondrial stress-induced cell death in AML has not been well explored. We demonstrate that AML cells are susceptible to mitochondrial targeted agents such as ONC201, an agonist of the mitochondrial protease ClpP, and gamitrinib, an inhibitor of mitochondrial chaperone TRAP1, however, these agents also …
