Locality-Aware Tail Node Embeddings On Homogeneous And Heterogeneous Networks, Zemin Liu, Yuan Fang, Wentao Zhang, Xinming Zhang, Steven C. H. Hoi

Research Collection School Of Computing and Information Systems

While the state-of-the-art network embedding approaches often learn high-quality embeddings for high-degree nodes with abundant structural connectivity, the quality of the embeddings for low-degree or nodes is often suboptimal due to their limited structural connectivity. While many real-world networks are long-tailed, to date little effort has been devoted to tail node embeddings. In this article, we formulate the goal of learning tail node embeddings as a problem, given the few links on each tail node. In particular, since each node resides in its own local context, we personalize the regression model for each tail node. To reduce overfitting in the …

Sgsh : Stimulate Large Language Models With Skeleton Heuristics For Knowledge Base Question Generation, Shasha Guo, Lizi Liao, Jing Zhang, Yanling Wang, Cuiping Li, Hong Chen

Research Collection School Of Computing and Information Systems

Knowledge base question generation (KBQG) aims to generate natural language questions from a set of triplet facts extracted from KB. Existing methods have significantly boosted the performance of KBQG via pre-trained language models (PLMs) thanks to the richly endowed semantic knowledge. With the advance of pre-training techniques, large language models (LLMs) (e.g., GPT-3.5) undoubtedly possess much more semantic knowledge. Therefore, how to effectively organize and exploit the abundant knowledge for KBQG becomes the focus of our study. In this work, we propose SGSH — a simple and effective framework to Stimulate GPT-3.5 with Skeleton Heuristics to enhance KBQG. The framework …

To Protect Or To Hide: An Investigation On Corporate Redacted Disclosure Motives Under New Fast Act Regulation, Yan Ma, Qian Mao, Nan Hu

Research Collection School Of Computing and Information Systems

China adopted amendments allowing companies to redact filings without prior approval in 2016. Leveraging this change as a quasi-nature experiment, we explore whether managers utilize redacted information to withhold bad information in the more lenient regulatory environment. Our investigation uncovers a significant shift in managerial behavior: Since 2016, managers incline to employ redactions to obscure negative news rather than safeguarding proprietary data. Furthermore, we find that the poorer firm performance and a higher cost of equity are associated with the redacted disclosures after 2016, suggesting that investors perceive an increase in firm-specific risk attributed to withholding bad news through redactions.

Dappscan: Building Large-Scale Datasets For Smart Contract Weaknesses In Dapp Projects, Zibin Zheng, Jianzhong Su, Jiachi Chen, David Lo, Zhijie Zhong, Mingxi Ye

Research Collection School Of Computing and Information Systems

The Smart Contract Weakness Classification Registry (SWC Registry) is a widely recognized list of smart contract weaknesses specific to the Ethereum platform. Despite the SWC Registry not being updated with new entries since 2020, the sustained development of smart contract analysis tools for detecting SWC-listed weaknesses highlights their ongoing significance in the field. However, evaluating these tools has proven challenging due to the absence of a large, unbiased, real-world dataset. To address this problem, we aim to build a large-scale SWC weakness dataset from real-world DApp projects. We recruited 22 participants and spent 44 person-months analyzing 1,199 open-source audit reports …

Fully Automated Selfish Mining Analysis In Efficient Proof Systems Blockchains, Krishnendu Chatterjee, Amirali Ebrahimzadeh, Mehrdad Karrabi, Krzysztof Pietrzak, Michelle Yeo, Dorde Zikelic

Research Collection School Of Computing and Information Systems

We study selfish mining attacks in longest-chain blockchains like Bitcoin, but where the proof of work is replaced with efficient proof systems - like proofs of stake or proofs of space - and consider the problem of computing an optimal selfish mining attack which maximizes expected relative revenue of the adversary, thus minimizing the chain quality. To this end, we propose a novel selfish mining attack that aims to maximize this objective and formally model the attack as a Markov decision process (MDP). We then present a formal analysis procedure which computes an ϵ-tight lower bound on the optimal expected …

Closest Pairs Search Over Data Stream, Rui Zhu Zhu, Bin Wang, Xiaochun Yang, Baihua Zheng

Research Collection School Of Computing and Information Systems

��-closest pair (KCP for short) search is a fundamental problem in database research. Given a set of��-dimensional streaming data S, KCP search aims to retrieve �� pairs with the shortest distances between them. While existing works have studied continuous 1-closest pair query (i.e., �� = 1) over dynamic data environments, which allow for object insertions/deletions, they require high computational costs and cannot easily support KCP search with �� > 1. This paper investigates the problem of KCP search over data stream, aiming to incrementally maintain as few pairs as possible to support KCP search with arbitrarily ��. To achieve this, we …

The Effect Of Pcaob Inspections On Corporate Innovation: Evidence From Deficiencies About The Valuation Of Intangibles, Jungbae Kim

Research Collection School Of Accountancy

I examine the economic consequences on corporate innovation when PCAOB inspections cite auditors for insufficient procedures in auditing the valuation of intangibles. I find that the clients of deficient auditors recognize larger and timelier impairments of intangibles, suggesting that affected auditors increase scrutiny about the valuation of intangibles in subsequent audits. This effect obtains only for valuation-related deficiencies and is salient for the clients of auditors who receive such deficiencies repeatedly. I also document real effects that the clients of deficient auditors exhibit less use of external mergers and acquisitions—which yield recognizable intangibles whose valuation is subject to increased auditor …

Prosocial Ceos, Corporate Policies, And Firm Value, Mei Feng, Weili Ge, Zhejia Ling, Wei Ting Loh

Research Collection School Of Accountancy

This paper examines how chief executive officers' (CEOs') prosocial tendency influences corporate policies and firm value. We use individuals' involvement with charitable organizations as a proxy for prosocial tendency. We find that, compared to firms with non-prosocial CEOs, firms with prosocial CEOs have lower executive subordinate turnover, implement more employee-friendly policies, experience higher customer satisfaction, and engage in more socially responsible activities. We also find that firms with prosocial CEOs have higher value and lower risk, partly due to the corporate policies adopted by prosocial CEOs. These results are corroborated when we compare changes in corporate policies and firm value …

When Do Corporate Good Deeds Become A Burden? The Role Of Corporate Social Responsibility Following Negative Events, Changhyun Kim, Yoonseok Zang, Heli Wang, Kate Niu

Research Collection School Of Accountancy

This study investigates the differential roles of corporate social responsibility (CSR) in the context of negative events. By categorizing CSR and negative events by their respective stakeholder groups, primary and secondary stakeholders, we theorize and test differential impacts of CSR and their interaction effects with different types of negative events. We propose that, while CSR toward secondary stakeholders offers the monotonous risk-tempering effect, CSR toward primary stakeholders has heterogeneous effects when facing negative events. Specifically, the effect of CSR toward primary stakeholders varies with the type of negative events. When negative events are associated with secondary stakeholders in the domain …

Public Data Resources And Total Factor Productivity Of Enterprises: A Quasi-Natural Experiment Based On Local Government Data Opening, Wuping Wu, Qiheng Li, Liuyi Zhang, Yue Zhao

Research Collection School Of Accountancy

The opening of public data is the government’s major strategic move to release the value of data factor. However, whether these data resources are used by the public to release their value needs to be empirically tested. Therefore, based on the perspective of high-quality development of firms, this paper examines the relation between open public data and firms’ total factor productivity so as to reflect the value of public data resources in driving force of promoting firms’ high-quality development. Taking A-share listed firms from 2010 to 2019 as samples, using a natural experiment based on the launch of the local …

Analyzing Swimming Performance Using Drone Captured Aerial Videos, Ngoc Doan Thu Tran, Kenny Tsu Wei Choo, Shaohui Foong, Hitesh Bhardwaj, Shane Kyi Hla Win, Wei Jun Ang, Kenneth T. Goh, Rajesh Krishna Balan

Research Collection School Of Computing and Information Systems

Monitoring swimmer performance is crucial for improving training and enhancing athletic techniques. Traditional methods for tracking swimmers, such as above-water and underwater cameras, face limitations due to the need for multiple cameras and obstructions from water splashes. This paper presents a novel approach for tracking swimmers using a moving UAV. The proposed system employs a UAV equipped with a high-resolution camera to capture aerial footage of the swimmers. The footage is then processed using computer vision algorithms to extract the swimmers' positions and movements. This approach offers several advantages, including single camera use and comprehensive coverage. The system's accuracy is …

Community and Regional Planning Program: Professional Projects

To assist the city of Concord in achieving its housing goals as presented in its general plan, while still meeting the stormwater discharge requirements laid out in the city’s municipal discharge permit, I worked with local developers and consultants to create a spreadsheet modeling tool that allows housing developers to estimate the total cost of green stormwater infrastructure needed to comply with local regulations.

This report contains a summary of the conditions leading to the necessity of this tool, the steps the tool takes that go beyond existing models, a description of how the model operates, instructions on how to …

Parent Strategies For Antiracist Parenting In Families Of Multiracial And Asian Descent, Matlida Tavares

Doctoral Dissertations

The Pew Research Center’s analysis of United States census data depicts and increasing number of individuals identifying as more than one race. From 2010 to 2020, the population had nearly doubled to 13.5 million. This is particularly evident in states with large populations of Asian American communities such as California, where nearly two million people identify as multiracial and people identifying as both White and Asian making up the largest portion of the 61% increase the state saw since 2010 (Henderson, 2022). Despite claims that an increase in multiracial individuals signifies an end of racism, multiracial children, navigating complex ethnic …

Purpose, Practical Wisdom, And The Formation Of Trustworthy Lawyers, Kenneth Townsend

Mercer Law Review

Lawyers have a “special responsibility for the quality of justice” in our nation and are expected to “further the public’s understanding of and confidence in the rule of law and the justice system” since “legal institutions in a constitutional democracy depend on popular participation and support to maintain their authority.” Upholding these and other commitments enables the profession to promote the “public interest,” according to the Preamble to the Model Rules of Professional Conduct.

Putting The Lawyer First: Framing Well-Being In Law As An Ethical Dilemma, Aric Short

Mercer Law Review

A disturbingly high percentage of our students continue to be unwell. In the most recent and comprehensive survey of law student well-being in 2021, almost 70% of law students responded that, in the past twelve months, they believed they needed to seek help for emotional or mental health problems. Embedded screening tools in the survey suggested that 34% of respondents were clinically depressed and 54% suffered from clinical anxiety. 44% of respondents reported being drunk in the past thirty days, 33% had engaged in binge drinking in the preceding two weeks, and 38% had smoked marijuana in the past twelve …

Reflections On Purpose And Professional Identity Formation, Harmony Decosimo

Mercer Law Review

I am very grateful to Professor Daisy Floyd for starting this important conversation about the role of purpose in professional identity formation, and for inviting me to participate in it. As I know my co-panelists agree, this is an important conversation not simply to us as lawyers, but as humans, trying to help each other figure out how to live good, meaningful lives.

I think what might be most useful in my response to Professor Floyd is to turn at least initially from the theoretical to the personal and practical by offering some insight into my own experience with purpose …

Can Too Much Clarity Cause Confusion? A Case Study Of Mccalop V. State, Sutton M. Eggena

Mercer Law Review

In criminal trials, few elements wield as much influence over the outcome as expert testimony. Expert testimony serves as the bridge between complex subject matter and the understanding of lay jurors, often occupying a pivotal position in the pursuit of justice. Indeed, expert testimony can be the lynchpin on which a jury’s verdict turns. Picture a courtroom filled with jurors, each presumed to lack a deep understanding of the intricate dynamics of domestic abuse and the profound effects of battered person syndrome on individuals trapped in violent relationships. In pursuit of justice, these jurors lean on a singular source—an expert …

Tale As Old As Time: The Beauty And The Beast Of Probabilistic Genotyping And Its Use In Georgia, Elizabeth Mcdaniel

Mercer Law Review

Deoxyribonucleic acid or as most of us prefer to call it—DNA—is a molecule in an organism that allows the organism to develop and function by carrying genetic information. DNA is what makes us unique. It was first observed in the late 1800s; however, its significance was not fully known until 1953. The use of DNA as evidence in criminal trials did not begin until the 1980s. Subsequently, the first statutes regarding DNA testing were passed in 1994 and 1997. Despite DNA’s late scientific discovery and its even later use in the legal profession, DNA has existed in organisms since their …

Actions Speak Louder Than Words: The Supreme Court Of Georgia Textualizes “Action” In The Georgia Constitution, Abigail C. Letts

Mercer Law Review

It comes as no surprise to those tuned into Georgia jurisprudence—textualism has taken root in the Supreme Court of Georgia. Since a series of holdings in the late twenty-tens including Olevik v. State, Georgia courts have produced a steady stream of decisions committed to pointing legal interpretation back to the intent of the framers. At first glance, the court’s proclamation in State v. SASS Group, LLC that “action” as it is used in Article I, Section II, Paragraph V(b) of the Georgia Constitution refers to an entire lawsuit appears simply to be another instance of the court’s staunch commitment …

Proprietors Beware: Recent Changes In Negligent Security Cases Involving Third-Party Criminal Acts And The State Of The Law Moving Forward After The Supreme Court Of Georgia’S Most Recent Decision In Georgia Cvs V. Carmichael, Blake Williamson

Mercer Law Review

The burgeoning surge in criminal activity within the United States has precipitated a corresponding increase in legal actions aimed at ascertaining the liability of business proprietors for crimes that transpire on their premises. Although the legal and factual questions surrounding the attribution of liability for the criminal acts of third parties often prove intricate, the crux of the matter remains consistent with that encountered in other premises liability actions—namely, did the proprietor possess superior knowledge of the danger that injured the plaintiff?

Sustainability: A Legal Value And A Legal Principle, Irma S. Russell

UMKC Law Review

Introduction to the symposium issue, Sustainability as a Legal Value and a Legal Principle. This issue explores the concept of sustainability as a legal principle, presents food for thought about sustainability development, and provides inspiration for climate action.

Stable State Societies In The Eye Of The Storm, John W. Ragsdale

UMKC Law Review

This Article will discuss the values and beliefs that are vital to sustainability and a prelude to the coming battle against the existential threat of climate change. It will examine the components of the core of a homeostatic, balancing-seeking entity that itself is in constant, rhythmic, corrective motion. The stable state counters the incessant, swirling forces that surround the peace within. Paradoxically, the continued resilience of the sustainable state requires constant vigilance and maintenance.

Still Not At All: Environmental Sustainability In The Supreme Court, James R. May

UMKC Law Review

Some predicted that the Court and litigants would make sustainability principles juridically relevant. Yet this article takes a fresh look and finds express invocation of sustainability still lacking not only in the U.S. Supreme Court but virtually throughout the U.S. federal judicial system comprised of the Supreme Court, 13 federal appellate courts, and 94 federal district courts. Part II tells the story of sustainable development's continued march as a legal principle. Part III engages sustainability jurisprudence before the U.S. Supreme Court and otherwise in the federal court system. It concludes that not only the U.S. Supreme Court but the entire …

Protecting Water, Sustaining Communities: Transforming Groundwater Management Entities Into Sources Of Power During And After Environmental Crises, Sarah Matsumoto

UMKC Law Review

Groundwater serves as a vital, limited resource for people all over the world. The United States Geological Survey reports that about 140 million people in the United States rely on groundwater for drinking water, of those, almost 43 million people rely on groundwater from domestic (or private, non-public supply) wells. In rural areas, groundwater is often the only available source of drinking water, making protection of groundwater quality in these regions a paramount concern.

Mirroring the various state regulatory approaches to groundwater management and protection, much of the recent media coverage of groundwater in the West focuses on water allocation …
