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 …

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, …

How Do Institutional Investors Facilitate Reporting Comparability? Evidence From Common Institutional Ownership In The United States, Xuanbo Li, Yun Lou, Rencheng Wang, Kaitang Zhou

Research Collection School Of Accountancy

We examine how common institutional investors (CIIs) facilitate the financial reporting comparability (FRC) of US firms. Common ownership increases FRC of firms that are directly owned by CIIs (via a direct effect) and has positive spillover effects on other firms in the same industry. We find spillover effects in two types of firms: (1) those that are commonly owned by different institutional investors but are connected through common firms, and (2) those that do not have any common ownership. These results suggest that the effect of common ownership goes beyond commonly owned firms and extends to non-commonly owned firms. Furthermore, …

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 …

Pension Participation Among Different Migrant Groups In China: Job Type, Regional Disparities, And Cross-Provincial Mobility, Boxia Xu

Dissertations

As China undergoes rapid economic transformation and urbanization, the migrant population has grown significantly. Although migrants play essential roles in the labor market, they face persistent structural barriers to pension access. Regional disparities, occupational segmentation, and cross-provincial mobility constraints affect the probability of their pension participation. While policy efforts aim to expand coverage, the fragmented nature of China’s pension system continues to hinder equitable access for migrants. As a result, ensuring pension participation among migrant groups remains a pressing challenge.

Using data from the 2014 China Migrants Dynamic Survey (CMDS), this dissertation employs logistic regression models to investigate how job …

Predicting Consumers’ Purchase Intention Of Browsed Products: A Study Based On Eye‑Tracking, Feiyan Jia, Choon Ling Sia, Yani Shi, Fiona Fui-Hoon Nah, Keng Siau

Research Collection School Of Computing and Information Systems

Predicting consumers’ purchase intention of browsed products enables sellers to implement nuanced promotion strategies to stimulate purchase. But how can we predict consumers’ purchase intention of browsed products? Our research demonstrates that consumers’ eye movement data collected when they browse products can serve this aim. We train and test the prediction model using logistic regression and random forest algorithms. Using data collected in a laboratory experiment, our empirical results show that both algorithms perform much better than a random guess, and the logistic regression performs slightly better than the random forest. Our findings imply that eye movement data enable sellers …

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’. …

The Risk Of Marginal Inclusion In The Fortune 500: A Quasi-Replication Of Lewis & Carlos (2023), W. Chad Carlos, Yasir Dewan, Ben W. Lewis, Brian P. Reschke, S. Isaac St. Clair

Faculty Publications

Conventional wisdom suggests that being included in an exclusive ranking leads to positive external evaluations. However, Lewis and Carlos (2023) found that firms situated near the threshold for inclusion on the 100 Best Corporate Citizen ranking were devalued by investors. To assess the generalizability of this surprising finding, we quasi-replicate and extend this finding by applying the same regression discontinuity design to the Fortune 500 ranking. We find corroborating evidence: firms near the bottom of the Fortune 500 receive lower external evaluations, not only from investors but also from industry peers. Our findings therefore quasi-replicate and extend Lewis and Carlos’ …

Linear Mixed Model For The Surface Roughness Prediction In Hard Turning Operation, Prithbey Raj Dey, David Lee Enke

Engineering Management and Systems Engineering Faculty Research & Creative Works

Surface machining using hard turning is an intricate operation due to the influence of multiple machining parameters, their non-linear interactions, and the inherent variability introduced by different experimental trials. This study proposes a Linear Mixed Model (LMM) for predicting surface roughness, effectively addressing the challenges in traditional linear models, posed by the influencing factors, non-linearity, and interactions. The LMM incorporates variability from both fixed effects, such as cutting parameters (feed rate, depth of cut, and cutting speed), and random effects arising from tool wear across experimental runs. As a result, it provides a more comprehensive understanding of how these factors …
