On Sgx’S Voyage To Corporate Sustainability: Exploring Emerging Topics In Multi-Industry Corpora, Xinwen Ni, Min Bin Lin, Simon J.D. Schillebeeckx, Wolfgang Karl Hardle

Research Collection Lee Kong Chian School Of Business

Topic modeling and LDA (Latent Dirichlet Allocation) have proven valuable in various fields as an innovative approach to studying areas of interest and identifying topics in a dynamic content. The underlying assumption is that techniques like LDA can swiftly capture emerging topics in textual documents compared to other categorization tools. These unsupervised approaches have been used to identify new industries and technological domains. However, our study on the nascent topic of “sustainability” within the corpora of SGX-listed companies highlights clear limitations in employing techniques like LDA on sparse data. The dynamic LDA approach, also called DTM (Dynamic Topic Modelling),based on …

Adaptive Expectation, News Impact And Lending Rate Behaviour In Nigeria: Evidence From Garch Models, Innocent Chile Nzeh

CBN Journal of Applied Statistics (JAS)

This study investigates how adaptive expectations and news impact shape lending rate behavior in Nigeria within the framework of both symmetric and asymmetric GARCH models. Using monthly data spanning 2006M1 to 2024M5, the paper analyzes the persistence, volatility, and responsiveness of the prime lending rate to positive and negative news shocks. Three error distributions (Normal, Student’s t, and Generalized Error Distribution (GED)) were employed to ensure robust estimation. The findings reveal that, in all models, the recent past value of the prime lending rate has a positive and sig nificant impact on the current value, indicating the presence of adaptive …

Relative Price Changes And Monetary Policy Stance In Nigeria, Elijah A. Udoh, Ibrahim D. Mohammed, Yakubu M. Sanusi, Philom Ena Y. Oksakei

CBN Journal of Applied Statistics (JAS)

This study estimates a baseline Taylor Rule and an augmented Taylor Rule incorporating relative price movements (RELP) using Generalized Method of Moments (GMM) on Nigerian data. The baseline model shows weak and statistically insignificant responses of the MPR to inflation, the output gap, and crisis conditions, confirming earlier findings that inflation and output in Nigeria do not have contemporaneous effects on the MPR. By contrast, the augmented model reveals that the relative price level positively and significantly influences the policy rate, indicating that the CBN raises interest rates when domestic prices rise relative to external or bench mark prices. Across …

The Dead Internet Theory: A Survey On Artificial Interactions And The Future Of Social Media, Prathamesh Muzumdar, Sumanth Cheemalapati, Srikanth Reddy Ramireddy, Kuldeep Singh, George Kurian, Apoorva Muley

Faculty Publications - The LeMoyne Smith School of Business

The Dead Internet Theory (DIT) suggests that much of today’s internet, particularly social media, is dominated by non-human activity, AI-generated content, and corporate agendas, leading to a decline in authentic human interaction. This study explores the origins, core claims, and implications of DIT, emphasizing its relevance in the context of social media platforms. The theory emerged as a response to the perceived homogenization of online spaces, highlighting issues like the proliferation of bots, algorithmically generated content, and the prioritization of engagement metrics over genuine user interaction. AI technologies play a central role in this phenomenon, as social media platforms increasingly …

Adaptive Volatility Forecasting Models, Jeffrey K. Tan

Master's Theses

In finance, risk is often quantified by volatility, and computing accurate volatility forecasts — while vital to financial decision making — remains one of the most challenging tasks in financial modeling. This thesis, motivated in part by the Black-Scholes-Merton Model and its limitations, adopts a statistical approach to volatility forecasting. The two main models of interest are the Exponential Weighted Moving Average (EWMA) model and the GARCH(1,1) model. Specifically, this work expands upon a potential adaptive lambda algorithm for EWMA models first proposed by Bernard Bollen (2014), and this work also utilizes the Momentum of Predictability (MoP) to generate adaptive …

Evaluating Nanobubble-Enriched Water Treatments For Cleaning Stainless Steel Winery Tanks At The Gallo Winery Research Station In Livingston, California, Edgar Godoy-Garcia

Master's Theses

ABSTRACT

Evaluating nanobubble-enriched water treatments for cleaning stainless steel winery tanks at the Gallo winery research station in Livingston, California.

Edgar A. Godoy-Garcia

Sanitation of stainless steel wine storage tanks is a critical component of quality control in commercial winemaking operations. Ineffective cleaning can lead to microbial contamination, product spoilage, and safety concerns. Traditionally, wineries rely on manual scrubbing, chemical cleaning agents, and extensive water rinsing cycles to maintain sanitary tank conditions. However, these methods are resource-intensive and may pose risks to both workers and the environment due to chemical exposure and wastewater generation. In response to growing industry interest …

Dentistry And The Law: Can I Use Patient Information To Respond To Internet Criticism?, Daniel Schulte J.D.

The Journal of the Michigan Dental Association

This legal guidance addresses dentists' inability to respond to negative online reviews using patient information. The article explains that HIPAA and Michigan's Dentist-Patient Privilege Statute prohibit healthcare professionals from disclosing patient information without authorization, even when defending against false or defamatory online posts. Unlike patients who can freely share information about their treatment, dentists face significant legal restrictions. The author notes that legal recourse is often difficult due to challenges in proving poster identity, distinguishing factual statements from opinions, and demonstrating specific damages. The recommended approach is to avoid responding to negative posts and instead focus on reputation management through …

The New Professional: Demystifying Dental Insurance For The New Professional, Amrita Patel D.D.S.

The Journal of the Michigan Dental Association

This comprehensive guide explains dental insurance complexities for new associates and practice owners.

Key business considerations include in-network versus out-of-network decisions, with in-network providing patient attraction but reduced reimbursements, while out-of-network allows fee control but limits patient base. The article addresses practical challenges including write-offs (difference between standard fees and insurance …

A Rating System To Evaluate Non-Gaap Exclusion Quality, Patricia M. Dechow, Wei Ting Loh, Annika Yu Wang

Research Collection School Of Accountancy

We develop a rating system to evaluate the quality of individual non-GAAP exclusions. Our perspective is that high-quality exclusions reflect nonrecurring economic transactions, are transitory accounting adjustments, or have little usefulness in forecasting cash flows. We use four approaches to rate exclusions. We evaluate the serial correlation of the exclusion, survey accounting academics’ views, obtain practitioner ratings from the CFA Institute, and identify the exclusions approved by the Chinese securities regulator. A firm’s exclusion quality score is the weighted average rating of its individual exclusions. For our sample of S&P 500 firms, we document that exclusion quality varies by industry, …

Capacity Investment In The Presence Of Correlated Demand And Production Resource Uncertainties And Its Implications For Financial Hedging, Onur Boyabatli, Guiyun Feng

Research Collection Lee Kong Chian School Of Business

In manufacturing firms, besides demand uncertainty, capacity investment decisions may also be subject to uncertainty in the availability of a production resource (e.g., budget or commodity component) which may become constraining for manufacturing. When the production resource uncertainty is tied to a financial index (e.g., asset or commodity price), the firm can enter into financial hedging contracts at the time of capacity investment to engineer this uncertainty. Our paper characterizes the optimal capacity investment and hedging decisions and examines how production resource uncertainty impacts the firm’s decisions, profitability, and the value of hedging. We identify three key drivers of these …

Paradoxical Leadership As Facilitator In The Idea Journey: The Role Of Regulatory Focus, Irene E. De Pater, Shenghui Wang, Ming Yi, Eric F. Rietzschel

Research outputs 2022 to 2026

Drawing upon theory and research on innovation, conservation of resources, and paradoxical leadership, we examine relationships between three stages of the innovative process (i.e., idea generation, idea dissemination, and idea implementation) and the role of paradoxical leadership as a facilitator of the transitions between these stages. In addition, we examine the motivational mechanisms (promotion and prevention focus) that can explain the relevance of paradoxical leadership in the innovative process. Results of a four-wave study show that paradoxical leadership, through employee promotion focus, strengthens the relationship between idea generation and idea dissemination, whereas paradoxical leadership, through employee prevention focus, strengthens the …

Research outputs 2022 to 2026

With the growing demand for sustainable and transparent food supply chains, consumer awareness of Halal integrity is rising, highlighting the need for a Halal food traceability system to enhance consumer confidence by providing detailed production information. However, the factors influencing consumer acceptance of such systems in Indonesia remain unclear. This study addresses three key objectives: (1) assessing consumer intention to use a Halal food traceability system; (2) exploring the relationships between system quality, information quality, service quality, performance expectancy, effort expectancy, social influence, and trust and consumer behavioural intention; and (3) evaluating the effectiveness of an integrated model combining the …

Stress Reactivity And Sociocultural Learning: More Stress-Reactive Individuals Are Quicker At Learning Sociocultural Norms From Experiential Feedback, Shilpa Madan, Krishna Savani, Pranjal H. Mehta, Desiree Y. Phua, Ying-Yi Hong, Michael W. Morris

Research Collection Lee Kong Chian School Of Business

When interacting with others in unfamiliar sociocultural settings, people need to learn the norms guiding appropriate behavior. The present research investigates an individual difference that helps this kind of learning: stress reactivity. Interactions in an unfamiliar sociocultural setting are stressful, particularly when the actor fails to follow its rules. Although stress is typically considered a liability, more stress-reactive individuals may be more motivated to improve, and, thus, quicker to learn these rules. Consistent with this idea, a pilot study found that people genetically inclined to stress reactivity, as computed by a genetic profile score across 59 single nucleotide polymorphisms on …

Major Customers And Carbon Footprints Along The Supply Chain, Saiying Deng, Tinghua Duan, Frank Weikai Li, Xiaoling Pu

Research Collection Lee Kong Chian School Of Business

This paper examines whether major corporate customers curb corporate carbon emissions along the supply chain. We show that suppliers with a more concentrated customer base have significantly lower carbon emissions. The results are robust to alternative measures of carbon emissions and customer concentration, alternative sample, alternative explanation, and various approaches to mitigate endogeneity concerns. The effect is more pronounced when major customers have made emission-reduction commitment, when they are exposed to greater climate regulatory shocks and risks, and when they become more concerned about regulatory scrutiny. Moreover, the curbing effect of major customers on supplier carbon emissions is stronger when …

The Gender Effects Of Covid: Evidence From Equity Analysts, Frank Weikai Li, Baolian Wang

Research Collection Lee Kong Chian School Of Business

We use COVID-19 and sell-side analysts as an experiment to study the effects of gender on labor productivity. We find that the forecast accuracy of female analysts declined more than that of male analysts, especially when schools were closed and among analysts who were more likely to have young children, were inexperienced, were busier, or lived in southern states of the US. Relative to male analysts, females also reduced their forecast timeliness and resorted to more heuristic forecasts but did not reduce coverage or updating frequency. Relative to pre pandemic, female analysts’ careers were more negatively affected than male analysts’. …
