A Settlement By “Any Other Name”: Evaluating The Sustainability Of Settlement Mechanisms, Dorcas Quek Anderson

Research Collection Yong Pung How School Of Law

Private settlements have been consistently encouraged by the Singapore civil justice system. Depending on the context, the settlement may take on many forms, including consent orders and settlement agreements. This begs the question of whether the exact form of settlement matters, or whether a settlement “by any other name” suffices. This article proposes the concept of “sustainable settlements” – comprising the measures of ease of enforcement, finality, and confidentiality – to holistically appraise the effectiveness of settlement mechanisms. The assessment of six settlement mechanisms using these measures clearly indicates that not every mechanism is equally sustainable. Exploring settlement amidst the …

A Difficult Act To Maintain, J.G. Allen

Research Collection Yong Pung How School Of Law

In "Where is Singapore's AI regulation headed?" (Issues, Summer 2025), Manoj Harjani starts by recounting its delicate balancing act in governing artificial intelligence. The city-state is able to maintain credibility on the global stage while remaining pragmatically grounded in technical experimentation, maintaining policy realism without overcommitting to rigid legal frameworks. The choice to adopt a regulatory “light touch” is often framed as a way to maintain flexibility, avoid overregulation, and enable innovation. But this obscures the extent to which this posture is itself a political and economic settlement—one that reinforces Singapore’s position in the global digital economy by facilitating capital …

Temporal Patterns Of New Product Introductions And Ipo Value: The Importance Of Recency, Dispersion, And Asymmetry, Suyun Mah, Rebecca J. Slotegraaf, Girish Mallapragada

Research Collection Lee Kong Chian School Of Business

A firm’s innovation activity is often judged by the number and type of new products it launches, but when these products are introduced may be equally important, especially before going public. This research investigates how the temporal pattern of new product introductions (NPIs) influences a firm’s initial public offering (IPO) value. The analysis uses data from 298 firms that went public between 2006 and 2023, and focuses on three patterns of timing: recency (how recently the latest product was launched before the IPO), dispersion (the degree to which NPIs before the IPO are spread out over time), and asymmetry (how …

Why Stressed Candidates Make Better Cross-Cultural Hires, Shilpa Madan

Research Collection Lee Kong Chian School Of Business

When interviewing job candidates, you may look for evidence that they stay calm under pressure and interpret signs of stress as red flags. However, our recent research shows that for cross-cultural positions, those red flags might actually indicate your best potential hires. Candidates who exhibit signs of stress may be better suited to navigate the complexities of cross-cultural roles, suggesting a need to reassess traditional interview evaluations.

A New Era Of Zines: Taking Lessons From The Past To Combat Intellectual And Political Fascism, Catherine Kane

Book Publishing Final Research Papers

Zines have long functioned as a way to circumvent the traditional gatekeepers of news, art, mainstream narratives, and publishing. They are largely non-commercial, and their emphasis is to put the means of production and distribution directly into the hands of the individual. Although their roots are in DIY, proletariat culture, they are now the subject of study in museums, libraries, and higher education, and have been co-opted by big brands, media outlets, and publishing houses—the institutions they originally sought to undermine.

In their most authentic form, zines have represented free thinking and speech, while giving individuals and communities a rallying …

Research outputs 2022 to 2026

The growing demand for Lithium-Ion batteries (LIBs) for use within varied electronics and electric vehicles (EVs) has raised concerns about the sustainability of lithium extraction from natural deposits. This study provides a comprehensive comparison of lithium recovery through mining of spodumene deposits, and the recovery of lithium from used batteries via recycling, in terms of technological, economic and environmental impacts. Lithium recovered through mining and refining operations prompt significant land disruption and soil contamination and possess large ecological, water and carbon footprints. Contrastingly, lithium recovered through battery recycling undergoes successive heat and chemical treatments, leading to waste minimisation and a …

Do Companies’ Green Credentials Enhance Trade Credit Provisions? Global Evidence, Rashid Zaman, Nader Atawnah, Deepa Banigidadmath, Muhammad Nadeem, Jia Liu

Research outputs 2022 to 2026

We investigate the impact of corporate renewable energy (RE) adoption on suppliers’ trade credit provisions. Using a global sample of 30 countries, we establish that firms engaging in higher RE consumption secure increased trade credit. Our results remain robust to a variety of sensitivity tests and after accounting for potential endogeneity concerns using the Paris Agreement and companies switching to green energy as exogenous shocks. Our channel analysis reveals that RE take-up mitigates companies’ environmental risk (proxied by environmental violation fines, media coverage of environmental controversies, GHG emissions, and environmental policy stringency). Additional tests reveal that the relationship between RE …

Death Penalty For Drug Offenders In Southeast Asia: Weakening Of Resistance To Change?, Wing Cheong Chan

Research Collection Yong Pung How School Of Law

Although the global movement towards abolition of the death penalty has been supported by an increasing number of countries in the world, the number of persons executed for drug offences actually increased in the last few years. Known executions for drug offences now account for more than 40 per cent of all global executions. Most such executions take place in Asia. Of the 34 countries in the world that still retain the death penalty for drug offenders, all nine of those identified as “high application states” (China, Indonesia, Iran, Kuwait, Malaysia, North Korea, Saudi Arabia, Singapore and Vietnam) are found …

Bridging The Great Wall: China’S Evolving Cross-Border Data Flow Policies And Implications For Global Data Governance, Sheng Zhang, Henry S. Gao

Research Collection Yong Pung How School Of Law

Despite the rapid expansion of the digital economy, the global regulatory framework for data flows remains fragmented, with countries adopting divergent approaches shaped by their own regulatory priorities. As a key player in the Internet economy, China’s approach to cross-border data flows (CBDF) not only defines its domestic digital landscape but also influences emerging global norms. This paper takes a comprehensive view of the evolution of China’s CBDF regime, examining its development through both domestic and international lenses. Domestically, China’s regulation of CBDF has evolved from a security-first approach to one that seeks to balance security with economic development. This …

Experimental And Theoretical Studies Of Novel Resilient Smart Shear Keys For Speedy Functional Recovery Of Highway Bridges After Extreme Events, Xinzhe Yuan, Jun Han, Jian Zhong, Haibin Zhang, Genda Chen

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

Sacrificial shear keys in small-to-medium-span highway bridges mainly provide lateral support to the bridge superstructure under extreme events such as earthquake and/or tsunami. However, such support could lead to irreparable harm to important bridge elements like abutments and bent caps (base), delaying the functional recovery of bridges in the aftermath. In addition, existing designs of the shear key primarily emphasize resistant capacity but overlook resilience. This study introduces a new sliding, modular, adaptive, replaceable, and two-dimensional (SMART) shear key designed to enhance the resilience of I-girder highway bridges. The SMART shear key has three primary goals: 1) enabling the rapid …

Positive Effects Of Sulfates On Performance Of Cement Paste Incorporating Low-Grade, High-Aluminum Steel Slag, Nannan Zhang, Gao Deng, Wenyu Liao, Chuanlin Hu, Hongyan Ma

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

Steel slag with high aluminum (Al) content significantly delays the early hydration of cement when used as a supplementary cementitious material (SCM). To address this challenge, this study investigates the effects of gypsum (Gy) and sodium sulfate (SS) additions on the performance of cement pastes with 30 % high-Al ladle metallurgy furnace (LMF) slag. The mechanical properties, hydration kinetics, phase evolution, as well as the early-age hydration mechanism were explored. The results indicate that C3S hydration is substantially inhibited under high-Al conditions, mainly attributed to the rapid dissolution and reaction of reactive aluminates (particularly mayenite) in the slag. Both Gy …

What Are The Limits To Smart Innovation? The Digital Underground Initiative And New Frontiers Of “Smartness” In Singapore, Prerona Das, Orlando Woods, Lily Kong

Research Collection College of Integrative Studies

This paper argues that the emergence of new frontiers of smart transformation, such as underground spaces, can pose significant challenges to the implementation of “smart” technological solutions. Exploring the case of Singapore’s Digital Underground initiative, we show that elements such as material complexity, co-ordination between stakeholders, and the availability of appropriate regulatory and administrative frameworks can problematize the implementation of subterranean smart initiatives. By considering multistake-holder perspectives on these “more-than-technological” factors, this paper offers lessons for urban planners, policymakers, and developers in cities around the world that are keen to leverage technology to unlock the potential of underground space.

Public Support For And Reactive Behavior Toward Technological Risk Interventions: An Extension Of Secondary Risk Theory, Hye Kyung Kim, Rui Gu, Fiona Goh, Sonny Rosenthal, Shirley S. Ho

Research Collection College of Integrative Studies

Project Wolbachia is a dengue control initiative in Singapore. Guided by Secondary Risk Theory, this study examined how primary (dengue) and secondary (Wolbachia) threat and coping appraisals shape public support and reactive behavior toward the project. A nationally representative survey of 1,000 Singaporeans showed that support was positively linked to the perceived primary risk, the efficacy of the project and the government, while negatively related to the perceived secondary risk. Reactive behavior was positively associated with perceptions of both primary and secondary risk. Media attention and trust in the government indirectly influenced support and behavior moderated by knowledge.

Optimal Abort Policy For Mission-Critical Systems Under Imperfect Condition Monitoring, Qiuzhuang Sun, Jiawen Hu, Zhi-Sheng Ye

Research Collection College of Integrative Studies

Although most on-demand mission-critical systems are engineered to be reliable to support critical tasks, occasional failures may still occur during missions. To increase system survivability, a common practice is to abort the mission before an imminent failure. We consider optimal mission abort for a system whose deterioration follows a general three-state (normal, defective, failed) semi-Markov chain. The failure is assumed self-revealed, whereas the healthy and defective states have to be inferred from imperfect condition-monitoring data. Because of the non-Markovian process dynamics, optimal mission abort for this partially observable system is an intractable stopping problem. For a tractable solution, we introduce …

Banking On Incumbents: How Do Fintech Start-Ups Benefit From Collaborations, Theodor Florian Cojoianu, Pia Helbing, Vladimir Pazitka, Dariusz Wojcik, Beiyun Xiao

Research Collection College of Integrative Studies

We investigate whether collaborations with established incumbents bolster innovation and access to capital for FinTech start-ups. Collaborations increase patent applications and raise both short-and long-term citations. Collaborations with finance incumbents stimulate finance and technology citations and boost both short-and long-horizon venture capital fundraising. These effects persist after addressing endogeneity and conducting additional robustness tests. Theoretically, our findings test the resource based theory in the FinTech ecosystem and enrich the open innovation literature by showing that, despite power asymmetries, FinTech start-ups can sustain innovative momentum and capture innovation gains via collaborations with incumbents. Collaborations function as credible signals that confer capital …

Recurrent Autoregressive Linear Model For Next-Basket Recommendation, Tereza Zmeskalova, Antoine Ledent, Martin Spisak, Pavel Kordik, Rodrigo Alves

Research Collection School Of Computing and Information Systems

Next-basket recommendation aims to predict the (sets of) items that a user is most likely to purchase during their next visit, capturing both short-term sequential patterns and long-term user preferences. However, effectively modeling these dynamics remains a challenge for traditional methods, which often struggle with interpretability and computational efficiency, particularly when dealing with intricate temporal dependencies and inter-item relationships. In this paper, we propose ReALM, a Recurrent Autoregressive Linear Model that explicitly captures temporal item-to-item dependencies across multiple time steps. By leveraging a recurrent loss function and a closed-form optimization solution, our approach offers both interpretability and scalability while maintaining …

Storage Location Optimization In Automated Storage And Retrieval Systems: A Deep Reinforcement Learning Approach, Lingjun Wang, Aldy Gunawan, Pieter Vansteenwegen

Research Collection School Of Computing and Information Systems

This study investigates the optimization of storage location in automated storage and retrieval systems (AS/RS). We introduce an optimization approach based on the Deep Q-Network (DQN) algorithm to enhance warehouse task efficiency and minimize stacker travel during storage and retrieval. To accelerate the algorithm training process, we integrate a prioritized experience replay mechanism. Furthermore, we decouple action selection from value estimation within the DQN framework to address the issue of value overestimation. The proposed model is evaluated against three heuristic methods. The experimental results demonstrate that our approach significantly outperforms these baselines.

In Situ High-Temperature Raman Spectroscopy For Online Eaf Slag Analysis, Bohong Zhang, Hanok Tekle, Ronald J. O'Malley, Jeffrey D. Smith, Farhan Mumtaz, Jie Huang

Electrical and Computer Engineering Faculty Research & Creative Works

Real-time monitoring of slag chemistry is critical for optimizing Electric Arc Furnace (EAF) steelmaking operations, where dynamic variations in slag composition directly influence slag foaming, refractory degradation, and thermal efficiency. Conventional techniques such as X-ray fluorescence (XRF), Fourier-transform infrared (FTIR), and scanning electron microscopy coupled with energy-dispersive X-ray spectroscopy (SEM-EDS) are commonly used to analyze slag composition, but their offline nature and equipment constraints limit their applicability for online monitoring in harsh industrial environments. To address this challenge, we present an in situ, high-temperature analytical approach that integrates Raman spectroscopy with a custom-designed fiber-optic probe for real-time slag characterization at …
