Understanding Disputes Over Digitalization: A Perspective Of Cross-Border Central Bank Digital Currencies, Heng Wang

Research Collection Yong Pung How School Of Law

In a rapidly digitalizing world, complex disputes would arise due to the technological, regulatory and other complexities. Public and private actors—including central banks, financial institutions, tech firms, and law firms—need to understand the complexity of these disputes before determining whether and how to engage with ongoing digitalization. Given the fundamental role of currency in the world economy, this article examines central bank digital currency (CBDC) as a pivotal case study. CBDCs, representing the digitalization of central bank money, are a novel digital form of national currency issued by central banks. Various central banks, including those of the Eurozone, Switzerland, the …

Insolvency Law As A Catalyst For Growth, Aurelio Gurrea-Martinez

Research Collection Yong Pung How School Of Law

Insolvency law plays an essential role in the real economy. From an ex ante perspective, that is, before a situation of insolvency arises, the design of insolvency law affects how debtors and creditors make decisions. For instance, if creditors believe that an insolvency system does not protect their rights or it does not help them maximize their recoveries if their debtors become insolvent, they will rationally become reluctant to extend credit. Therefore, an unattractive insolvency regime for creditors will harm firms’ access to finance and the promotion of economic growth. Similarly, an insolvency system that severely punishes honest but unfortunate …

Mitigating Nonlinear Impairments In High-Speed Optical Communication Systems Via Volterra Nonlinear Equalizer, Safa Jabbar Mohammed, Jalil A. Hamadamin

Polytechnic Journal

This paper presents an in-depth investigation into applying a frequency domain Volterra series nonlinear equalizer (FD-VNLE) to mitigate nonlinear impairments in optical communication systems operating at high speeds. The study aims to address the issues presented by nonlinear effects, specifically self-phase modulation (SPM), which significantly degrades system performance at higher power levels. A comprehensive mathematical model of the FD-VNLE was developed to provide theoretical insight, while its implementation was carried out using MATLAB co-simulated with OptiSystem. The performance of the 40 Gbps dual-polarization quadrature phase shift keying (DP-QPSK) system was rigorously evaluated, focusing on critical performance metrics like bit error …

A Proposed Mathematical Framework For Fuzzy It Service Management (F-Itsm) And Neutrosophic It Service Management (N-Itsm), Takaaki Fujita

Neutrosophic Systems with Applications

Fuzzy sets, rough sets, hyperrough sets, intuitionistic fuzzy sets, neutrosophic sets, plithogenic sets , and other frameworks for handling uncertainty are under active research every day. These concepts can model a wide range of real-world phenomena and are frequently investigated to facilitate more efficient decision-making. IT Service Management is a systematic approach to designing, delivering, managing, and improving IT services in alignment with organizational objectives. In this paper, we explore the Mathematical Frameworks for Fuzzy IT Service Management (F-ITSM) and Neutrosophic IT Service Management (N-ITSM), which combine these uncertainty-based ideas with IT Service Management practices.

Evaluating Disaster Relief In Supply Chains Using A Neutrosophic Mcdm Approach, Nada A. Nabeeh

Neutrosophic Systems with Applications

Disaster-prone regions and affected areas encounter persistent challenges in maintaining supply chain continuity due to environmental uncertainties and infrastructure disruptions. Effective supply chain disaster management (SCDM) is essential for relief disaster disruptions, specifically in upstream processes and functions within the humanitarian supply chain. The integration of advanced technologies like the metaverse and Multiple-Criteria Decision-Making (MCDM) methods supports strategic planning and enhances resilience. This study presents a multi-criteria decision-making (MCDM) proposed approach for disaster relief evaluation in supply chain management. The proposed model integrates Interval-Valued Neutrosophic Numbers (IVNNs) to manage uncertainty and ambiguity inherent in disaster various criteria which are often …

Aging And The Law In Singapore And Japan: Adult Guardianship And Other Alternatives, Hang Wu Tang, Yukio Sakurai, Yue-En Chong

Research Collection Yong Pung How School Of Law

Comparative adult guardianship law and other alternatives, especially in an Asian context, is an under-investigated area. This paper attempts to fill the gap in the literature by comparing the adult guardianship law and other alternatives from the perspectives of Singapore and Japan. The central argument of this paper is that in order for the law of adult guardianship to be widely adopted in Asian societies like Singapore and Japan - where much of adult guardianship related issues are governed by informal familial arrangements; this would require governments to do more than the mere enacting of adult guardianship legislation. To encourage …

Driving Financial Inclusion Through Central Bank Digital Currencies: A Methodology For Cbdc Implementation, Heng Wang

Research Collection Yong Pung How School Of Law

This publication outlines a methodology for the design, testing, and implementation of central bank digital currencies (CBDCs) to advance financial inclusion. As an increasing number of central banks around the world explore this novel form of financial infrastructure, this paper focuses on the potential of CBDCs to address key access and price barriers in developing and emerging economies. CBDCs, especially retail ones, can offer unique opportunities for enhancing financial services accessibility, affordability, and usability for unserved and underserved populations, if implemented responsibly through a structured, inclusive and user-centric approach.

Ai Governance And Algorithmic Auditing In Financial Institutions: Lessons From Singapore, Nydia Remolina Leon

Research Collection Yong Pung How School Of Law

This paper examines the role of algorithmic auditing as a mechanism for responsible AI development and deployment in the financial sector, with a particular focus on Singapore’s regulatory and institutional initiatives. Against the backdrop of fragmented global artificial intelligence (AI) governance frameworks, the study analyses how Singapore has developed operational tools — such as the Veritas Toolkit, AI Verify, Project Moonshot and Project Mindforge — that go beyond abstract ethical principles to provide measurable, use-case-specific standards for auditing AI systems. These initiatives contribute to standardising audit practices, enhancing transparency and bridging trust gaps between financial institutions, regulators and stakeholders. The …

Ecological Responsibility In The City: The Surfaces And Volumes Of Urban Mosquito Management, Orlando Woods, Sayd Randle

Research Collection College of Integrative Studies

This paper explores how ecological responsibility becomes distributed across the surfaces and volumes of the city. Our focus is urban mosquito management – specifically, the management of the Aedes aegypti mosquito, the vector by which dengue and several other diseases are transmitted to humans – and the governance strategies deployed in Singapore to manage breeding sites and mosquito outbreaks. Whilst the governance of nature in Singapore is usually undertaken by the state, the effective management of mosquitoes requires responsibility for ecological management to become distributed throughout the city. Residents are expected to assume responsibility for surficial cleanliness and the removal …

Infrastructural Splintering Along The Bri: Catholic Political Ecologies And The Fractious Futures Of Sri Lanka’S Littoral Spaces, Orlando Woods

Research Collection College of Integrative Studies

This article considers the ways in which the material infrastructures of China’s Belt and Road Initiative (BRI) intersect with other infrastructural formations, and how the resulting overlaps can trigger processes of what I call “infrastructural splintering”. These processes cause infrastructure to be experienced in differentiating ways, creating divisive politics where there might once have been unity. Embracing these politics as an analytical starting point undermines the techno-material stability of the BRI, and reveals its more-than-material affects. I illustrate these ideas by developing a case study of the effects of the China-backed Colombo Port City project on Catholic fishing communities that …

Emulating Empire: Washington’S Preoccupation With British Counterinsurgency In Malaya And U.S. Commitment To Vietnam, Wen-Qing Ngoei

Research Collection College of Integrative Studies

This essay examines how Washington’s deep preoccupation with the British-Malayan counterinsurgency tactics–tactics that routed the guerilla fighters of the Malayan Communist Party–shaped US commitment to Vietnam. This US preoccupation, stoked by Britain’s (and Malaya’s) promotion of their counterinsurgency knowledge to US leaders, also influenced the lessons that US analysts and thinkers absorbed from the United States’ defeat in Indochina. Most studies of British-Malayan counterinsurgency and its connection to the Vietnam War fixate upon debating the relevance of the former to the latter and how this bears on US failures in Indochina. However, this essay focuses on the understudied fervor with …

Awareness, Knowledge, And Motivations About Lifespan, Healthspan, And Healthy Longevity Medicine In The General Population: The Healthy Longevity (Helo) Conceptual Framework, Belinda Wang, Anna Szucs, Elena Sandalova, E. J. Horberg, Paul A. O'Keefe, Louis Island, Hans J. Meij, Sonny Rosenthal, Andrea B. Maier

Research Collection College of Integrative Studies

The global population is ageing and the gap between lifespan (total years lived) and healthspan (years lived free of diseases) is increasing. Healthy Longevity Medicine (HLM) is an approach to optimise health and healthspan, and it has substantial public health implications. Despite those implications, the understanding of public perspectives on this field is lacking. The HEalthy LOngevity (HELO) framework was developed through a literature review guided by expert discussions across disciplines to include evidence-based concepts of health-related decision-making, ageing, and HLM. The framework organises concepts into three components. The first two components, awareness and knowledge, explore public perception and understanding …

Research Collection College of Integrative Studies

Public electric vehicle charging stations (EVCSs) are vital for boosting EV adoption. This study investigates Seoul’s public EV charging patterns, taking into account the surrounding urban built environment. We collected built-environment data from land-use maps, Point of Interest (POI) data, and panorama images near public EVCS. The computer-vision technique was used to extract scene features from panorama images. We conducted a spatiotemporal analysis of public EVCS usage. The built-environment factors underwent dimensionality reduction and were assessed for outliers. Descriptive analysis revealed afternoon peak charging times and variations between chargers. Additional peaks are observed in the weekday late evening for chargers …

Techno-Geopolitics And Semi-Conductor Chokepoints: Beyond The Us-China Wto Dispute, Han-Wei Liu, Ching-Fu Lin

Research Collection Yong Pung How School Of Law

Much ink has been spilled on the US-China tech and trade war, particularly the role of US export controls in containing China and preserving America’s tech dominance. Less attention, however, has been paid to other critical nodes in the global semiconductor supply chain – Taiwan, South Korea, Japan, and the Netherlands – which we coin as ‘chokepoint economies’. Taiwan alone produces over 90% of the world’s most advanced chips, vital to the digital age and the future of AI in the Indo-Pacific and beyond. Using Taiwan as a case study, this paper shows how chokepoint economies navigate competing pressures amid …

The Moving Pieces Of Corporate Disclosure: Truth, Falsity, And Half-Truths In Between, Donald C. Langevoort

Georgetown Law Faculty Publications and Other Works

The half-truth doctrine is made operational in the common statutory and rule-based admonitions in the securities laws (particularly Rule 10b-5) not to omit “material fact[s] necessary in order to make . . . statements made . . . not misleading . . . .” It cabins the temptation to exploit the privilege of nondisclosure through what has been called “artful paltering.” Unfortunately, the evolution of the half-truth doctrine has become more of a poor stepsister than a muscular companion. It carries less than a full load in the complex ecosystem that exists for public company disclosure today. And it is …

Hypophosphatasia (HPP) is an inherited disorder that affects bone and tooth mineralization, among other body systems. HPP is caused by pathogenic variants in the alkaline phosphatase-liver (ALPL) gene, which encodes tissue nonspecific alkaline phosphatase. One major challenge in diagnosing HPP is interpreting variant of uncertain significance (VUS), which can create uncertainty for patients and healthcare professionals, leading to delays in diagnosis and treatment or incorrect diagnoses. Since February 2021, the ALPLgene variant consortium has reclassified 100 VUS using adjusted American College of Medical Genetics/Association for Molecular Pathology criteria. Of these, 11 were reclassified as pathogenic, 62 as …
