Beyond "Protected" And "Private": An Empirical Security Analysis Of Custom Function Modifiers In Smart Contracts, Yuzhou Fang, Daoyuan Wu, Xiao Yi, Shuai Wang, Yufan Chen, Mengjie Chen, Yang Liu, Lingxiao Jiang

Research Collection School Of Computing and Information Systems

A smart contract is a piece of application-layer code running on blockchain ledgers and it provides programmatic logic via transaction-based execution of pre-defined functions. Smart contract functions are by default invokable by any party. To safeguard them, the mainstream smart contract language, i.e., Solidity of the popular Ethereum blockchain, proposed a unique language-level keyword called “modifier,” which allows developers to define custom function access control policies beyond the traditional “protected” and “private” modifiers in classic programming languages.In this paper, we aim to conduct a large-scale security analysis of the modifiers used in real-world Ethereum smart contracts. To achieve this, we …

Investigating The Relationship Between Monetary Policy, Macro-Prudential Policy And Credit Risk In Indonesia Banking Industry, Cep J. Anwar, Indra Suhendra, Eka Purwanda, Agus Salim, Nur A. Rakhmawati, Ferry Jie

Research outputs 2022 to 2026

Using a novel panel data set we study the influence of monetary and macro-prudential policies on non-performing loans as a measure of credit risk in Indonesian banking industry from Q1 2010 to Q4 2022. The panel homogeneity assumption was verified through the utilization of the Chow and Roy-Zellner tests. The findings showed that the model was not homogenous, necessitating the use of the Pooled Mean Group (PMG) estimator. The results indicated that monetary and macro-prudential policies significantly impacted credit risk. Furthermore, tight monetary and macro-prudential policies increased and reduced credit risk in the long run, respectively. The findings also showed …

Southeastern Conference (Sec) International Student-Athlete (Isa) Career Transitions - A Cultural Intelligence (Cq) Perspective, Tsu-Lin Yeh

Theses and Dissertations

This dissertation investigated international student-athletes’ (ISAs’) transition experiences of being recruited for, matriculating in, and then leaving high-performance and commercialized Southeastern Conference (SEC) institutions. Adopting the Cultural Intelligence (CQ) theory, this dissertation specifically examined how the four CQ elements (metacognition CQ, cognition CQ, motivation CQ, and behavior CQ) existed in an ISA’s transition process. CQ explains a person’s capability for performing well in culturally diverse environments (Fang et al., 2018). Traditional CQ studies have been utilized to manage international organizations’ diversity and inclusion (Triandis, 2006), particularly regarding employee retention, career transition and development (Mangla, 2021). However, although sports management is …

Healthcare In The United States: Necessity Or Luxury? Analysis Of The Impact Of The Affordable Care Act On Elasticity Of Healthcare Expenditure, Daniel Asante

Doctoral Dissertations (DBA)

The debate over whether healthcare is a necessity or a luxury has sparked divergent findings among healthcare researchers. While some have gauged individual income elasticities, others have employed national or cross-national data to discern these elasticities. This paper contributes to this scholarly discourse by presenting fresh insights derived from a panel encompassing 50 US states from 1990 to 2020. The study investigates the impact of the Patient Protection and Affordable Care Act (ACA) on healthcare elasticity, utilizing both parametric and nonparametric models. Initial estimations using the Pooled Ordinary Least Squares (OLS) approach reveal elasticity coefficients above unity. However, estimations utilizing …

Effective Leader Development Within A Church-Planting Organization For A Changing And Chaotic World, Jeremy Davis

Electronic Theses and Dissertations

A challenge in cross-cultural church planting is developing leaders. Cross-cultural church-planting organizations like Latin American Mission (LAM; pseudonym) that lack a leadership development strategy struggle to form lasting leaders, sending missionaries with Biblical training but not leader development training. Additionally, developing leaders in a volatile, uncertain, complex, and ambiguous (VUCA) environment creates specific challenges that missionaries must address. The purpose of this qualitative, Delphi method study was to investigate the leadership development perceptions and experiences among existing LAM missionaries in the regions of Latin America (Colombia, Cuba, Mexico City, Peru, Brazil, and Ecuador) to provide suggestions for improving effective leadership …

Purpose In The For-Profit Firm: A Review And Framework For Management Research, Gerard George, Martine R. Haas, Anita M. Mcgahan, Simon J.D. Schillebeeckx, Paul Tracey

Research Collection Lee Kong Chian School Of Business

Purpose is a concept often used in managerial communities to signal and define a firm’s benevolent and pluralistic approach to its stakeholders beyond its focus on shareholders. While some evidence has linked purpose to positive organizational outcomes such as growth, employee satisfaction, innovation, and superior stock market performance, the definition and application of purpose in management research has been varied and frequently ambiguous. We review literature streams that invoke purpose in the for-profit firm and propose a unifying definition. Next, we develop a framework to study purpose that decouples its framing and formalization within firms from its realization, thus helping …

Theorizing About The Implications Of Multiplexity: An Integrative Typology, Gokhan Ertug, Julia Brennecke, Stefano Tasselli

Research Collection Lee Kong Chian School Of Business

Multiplexity, the coexistence of more than one type of relationship between two actors, is a prevalent phenomenon with clear relevance for a wide range of management settings and phenomena. While there is a substantial body of work on multiplexity, the absence of a shared terminology and a typology for the mechanisms and arguments that are used in theorizing about its implications nevertheless hamper its appeal to organizational network scholars and slow its progress. Based on content analysis of 103 studies, we propose “relational harmony,” “task complementarity,” and “relational scope” as three categories to integrate the mechanisms and arguments used in …

Career Choice Motivation For Commercial Pilots, Brett Watts

Doctoral Dissertations and Master's Theses

Career choice motivation research studies the factors involved during a person’s decision-making process regarding which career to pursue (Skatova & Ferguson, 2014). These factors are often studied in individuals who have not yet entered the workforce, such as students. Although there is a significant amount of research on career choice motivations for doctors, dentists, and other related fields, research on career choice motivations for pilots is sparse. As air traffic is expected to grow at approximately 4.7% per year for the next 20 years (Federal Aviation Administration, 2022), a key factor in the aviation industry’s growth is the availability of …

Inventory-Responsive Donor-Management Policy: A Tandem Queueing Network Model, Taozeng Zhu, Nicholas Teck Boon Yeo, Sarah Yini Gao, Gar Goei Loke

Research Collection Lee Kong Chian School Of Business

Problem definition: In the blood-donor-management problem, the blood bank incentivizes donors to donate, given blood inventory levels. We propose a model to optimize such incentivization schemes under the context of random demand, blood perishability, observation period between donations, and variability in donor arrivals and dropouts. Methodology/results: We propose an optimization model that simultaneously accounts for the dynamics in the blood inventory and the donor’s donation process, as a coupled queueing network. We adopt the Pipeline Queue paradigm, which leads us to a tractable convex reformulation. The coupled setting requires new methodologies to be developed upon the existing Pipeline Queue framework. …

Workplace Culture Must Emphasise Mutual Respect [In Chinese], Siow-Heng Ong

Research Collection Lee Kong Chian School Of Business

In a commentary, SMU Professor of Communication Management (Education) Ong Siow Heng discussed the importance of having a respectful culture in the workplace. He opined that one way to appreciate employees is to provide equitable pay and career advancement opportunities for staff, so that workers will know that their employer respects their contribution. Even though more forms of disrespect for workers are being addressed by law, Prof Ong opined that improving respect for the workers’ dignity is best managed by those in workplace leadership even before relevant laws are passed, especially in areas that cannot be covered by law. He …

Human Capital Effects In The Job Search Process For New Labor Market Entrants: A Double-Edged Sword?, Jomel Wei Xuan Ng, Zhaoli Song, Filip Lievens

Research Collection Lee Kong Chian School Of Business

Although traditional research on human capital shows that it enhances employment success, its role in the job search process is unclear. To explain its weak effects in previous studies, this study draws on goal system theory to propose that human capital may act as a double-edged sword: On one hand it facilitates the ease of gaining employment, on the other hand it may compromise the frequency of job search behaviors. We conducted a bi-weekly repeated survey study on new labor market entrants and measured human capital using academic achievement scores. Results confirmed that human capital, though instrumental for proximal job …

Blockchain And Regenerative Finance: Charting A Path Toward Regeneration, Marco Schletz, Axel Constant, Angel Hsu, Simon J.D. Schillebeeckx, Roman Beck, Martin Wainstein

Research Collection Lee Kong Chian School Of Business

The Regenerative Finance (ReFi) movement aims to fundamentally transform the governance of global common pool resources (CPRs), such as the atmosphere, which are being degraded despite international efforts. The ReFi movement seeks to achieve this by utilizing digital monitoring, reporting, and verification (D-MRV); tokenization of assets; and decentralized governance approaches. However, there is currently a lack of a clear path forward to create and implement models that actually drive the “Re-” in ReFi beyond perpetuating the existing extractive economics and toward actual regeneration. In addition, ReFi suffers from growing pains, lacking a common interoperability framework and definition for determining what …

Seeking Better Sharpe Ratio Via Bayesian Optimization, Peng Liu

Research Collection Lee Kong Chian School Of Business

Developing an excellent quantitative trading strategy to obtain a high Sharpe ratio requires optimizing several parameters at the same time. Example parameters include the window length of a moving average sequence, the choice of trading instruments, and the thresholds used to generate trading signals. Simultaneously optimizing all these parameters to seek a high Sharpe ratio is a daunting and time-consuming task, partly because of the unknown mechanism determining the Sharpe ratio. This article proposes using Bayesian optimization to systematically search for the optimal parameter configuration that leads to a high Sharpe ratio. The author shows that the proposed intelligent search …

Not A Box Of Nuts And Bolts: Distribution Channels For Specialty Drugs?, Liang Xu, Vidya Mani, Hui Zhao

Research Collection Lee Kong Chian School Of Business

One of the most important trends in the pharmaceutical industry is the rapid growth of specialty drugs. Specialty drugs, mostly bio based, tend to be high risk, high priced, and more regulated than traditional drugs, resulting in unprecedented challenges in distribution. Such challenges lead to the emergence of specialty distributors (SDs), which, compared with traditional wholesalers (WSs), represent a more controlled channel and carry a smaller variety of drugs. Due to the risky nature of specialty drugs, manufacturers must consider the trade-off between access and control in determining whether to use SDs (partially or exclusively). Using a unique dataset assembled …

Vehicle Rebalancing In A Shared Micromobility System With Rider Crowdsourcing, Ziliang Jin, Yulan Wang, Yun Fong Lim, Kai Pan, Zuo-Jun Max Shen

Research Collection Lee Kong Chian School Of Business

Problem definition: Shared micromobility vehicles provide an eco-friendly form of short-distance travel within an urban area. Since customers pick up and drop off vehicles in any service region at any time, such convenience often leads to a severe imbalance between vehicle supply and demand in different service regions. To overcome this, a micromobility operator can crowdsource individual riders with reward incentives in addition to engaging a third-party logistics provider (3PL) to relocate the vehicles. Methodology/results: We construct a time-space network with multiple service regions and formulate a twostage stochastic mixed-integer program considering uncertain customer demands. In the first stage, the …

Perspectives On The Impact, Mission And Purpose Of The Business School, Howard Thomas

Research Collection Lee Kong Chian School Of Business

The business school has been an important success story in the evolution of the modern university. The concept of how the impact, mission, purpose, and value of a management school should be formulated is often delegated to the dean, faculty and advisory committees in most schools. The British Academy has contributed significantly to the emerging debate on the purpose of a business school by both examining the concept of a purposeful business school in business and management education and, more recently, investigating what, and how, business schools should teach, grow and develop. Greater attention has been directed towards developing more …

Business Schools Should Be Schools Of Management: An Evolutionary Perspective, Kai Peters, Howard Thomas

Research Collection Lee Kong Chian School Of Business

This chapter looks at the original driving forces which led to the creation of institutions, particularly in the US, including the vision of their founders which would support our perspective in favour of schools of management. It looks at the years following the Second World War and how the Ford and Carnegie ‘Foundation Reports’ as well as the Cold War led to further evolution away from a school of management to a business school mission. The chapter looks at the period roughly from 1970 to 2000 during which US business school funding, which had been largely provided by the foundations, …

Insider Trading And Corporate Spinoffs, Charlie Charoenwong, Kuan Yong David Ding, Jing Pan

Research Collection Lee Kong Chian School Of Business

This paper studies insider trading to examine undervaluation as a motive behind corporate spinoffs. We show an unmistakable increase (decrease) in the number of insider purchases (sales) and net purchases (sales) in the four quarters prior to a spinoff announcement. In addition, relative to a benchmark period, insider selling is significantly lower, and their net purchases significantly higher, in the three quarters prior to a spinoff announcement compared to other periods. We find that announcement period excess returns for abnormal net insider purchases are significantly higher than excess returns for abnormal net insider sales. Moreover, only firms with abnormal net …

Why Employees Accept Lower Pay At Mission-Oriented Companies, Insiya Hussain, Marko Pitesa, Stefan Thau, Michael Schaerer

Research Collection Lee Kong Chian School Of Business

Today’s companies are likely to tout how their work benefits human welfare or “makes the world a better place.” Recent research suggests that this may come with a potential financial drawback for workers, as it can inhibit them from negotiating for higher pay. Over five studies, job candidates consistently reported that they worried asking for higher pay from these companies would be seen as greedy or inappropriate. This suggests they are aware of a common bias, known as motivation purity bias, where managers believe employees interested in material rewards of work (such as pay) are less motivated than those motivated …

Augmenting Fake Content Detection In Online Platforms: A Domain Adaptive Transfer Learning Via Adversarial Training Approach, Ka Chung Ng, Ping Fan Ke, Mike K. P. So, Kar Yan Tam

Research Collection School Of Computing and Information Systems

Online platforms are experimenting with interventions such as content screening to moderate the effects of fake, biased, and incensing content. Yet, online platforms face an operational challenge in implementing machine learning algorithms for managing online content due to the labeling problem, where labeled data used for model training are limited and costly to obtain. To address this issue, we propose a domain adaptive transfer learning via adversarial training approach to augment fake content detection with collective human intelligence. We first start with a source domain dataset containing deceptive and trustworthy general news constructed from a large collection of labeled news …

The Impact Of Upzoning On Housing Construction In Auckland*, Ryan Greenaway-Mcgrevy, Peter C. B. Phillips

Research Collection School Of Economics

There is a growing debate about whether upzoning is an effective policy response to housing shortages and unaffordable housing. This paper provides empirical evidence to further inform debate by examining the various impacts of recently implemented zoning reforms on housing construction in Auckland, the largest metropolitan area in New Zealand. In 2016, the city upzoned approximately three quarters of its residential land to facilitate construction of more intensive housing. We use a quasi-experimental approach to analyze the short-run impacts of the reform on construction, allowing for potential shifts in construction from non-upzoned to upzoned areas (displacement effects) that would, if …
