The Return Of Chinese Emigrants: Legal Barriers And Local Practices, Jiaqi M. Liu

Research Collection School of Social Sciences

While China has observed an increasing influx of foreign nationals, a notable phenomenon involves Chinese emigrants opting for return migration to reestablish themselves in their country of origin. The process of emigrants returning to China, referred to as “return and resettlement” (huiguo dingju 回国定居) in official terminology, however, is not automatic. Emigrant returnees must fulfill a set of selective and documentary criteria, implying that only economically affluent and duly documented migrants are permitted to resettle in China. Through a comprehensive review of national policies and an analysis of local practices in a diaspora hometown, this chapter argues that the hukou …

An Efficient Security-Enhanced Accountable Access Control For Named Data Networking, Jianfei Sun, Yuxian Li, Xuehuan Yang, Guomin Yang, Robert H. Deng

Research Collection School Of Computing and Information Systems

Named Data Networking (NDN) is embraced as the crucial implementation of Information-Centric Networking (ICN), enhancing content distribution and caching efficiency through edge routers. However, existing NDN architectures face significant security and privacy challenges, including: (a) a lack of secure and efficient access control; (b) inadequate support for flexible and selective content management by content publishers; (c) insufficient implementation of accountability and privilege revocation mechanisms. To handle these challenges, we propose ESAS, the first-ever Efficient Security-enhanced Accountable Access Control Scheme for NDN. Specifically, our ESAS incorporates anonymous authentication using group signatures at network routers to prevent unauthorized access, employs key-aggregation-based access …

Research Collection School Of Computing and Information Systems

DevOps education presents unique pedagogical challenges due to the diversity of tools, rapid technological change, and the multidisciplinary nature of the field. Although previous work has proposed recommendations to address these challenges, it is unclear how educators perceive these recommendations and whether they align with the challenges encountered in practice. In this paper, we present a quantitative and qualitative methods study involving 11 DevOps educators who interacted with Improve, a tool that presents a curated set of educational challenges and recommendations derived from previous literature. Educators indicated which recommendations they already use, which they intend to use, and which challenges …

Research Collection School Of Computing and Information Systems

Electric bikes powered by lithium-ion batteries are increasingly used in smart cities to promote sustainable mobility and efficient delivery services. However, limited battery range and slow plug-in charging remain key challenges. Shared electric bike battery systems, facilitated by battery swapping stations, offer a promising solution by enabling quick and efficient battery replacements. However, their success hinges on accurate anomaly detection, battery health estimation and remain range prediction. These tasks remain challenging due to data scarcity, battery diversity and environmental variability. Here we show that a large-scale lithium-ion battery model trained on over ten million battery time series data enables robust …

Stylegan-∞: Extending Stylegan To Arbitrary-Ratio Translation With Stylebook, Yihua Dai, Tianyi Xiang, Bailin Deng, Yong Du, Hongmin Cai, Jing Qin, Shengfeng He

Research Collection School Of Computing and Information Systems

Although pre-trained large-scale generative models StyleGAN series have proven to be effective in various editing and translation tasks, they are limited to pre-defined fixed aspect ratio. To overcome this limitation, we propose StyleGAN-∞, a model that enables pre-trained StyleGAN to perform arbitrary-ratio conditional synthesis. Our key insight is to distill the expressive StyleGAN features into a StyleBook, such that an arbitrary-ratio condition can be translated to other forms by properly assembling pre-defined StyleBook vectors. To learn and leverage the StyleBook, we employ a network with three distinct stages, each corresponding to StyleBook extraction, StyleBook correspondence learning, and arbitrary-ratio synthesis. Extensive …

Dgl: Dynamic Global-Local Information Aggregation For Scalable Vrp Generalization With Self-Improvement Learning, Yubin Xiao, Yuesong Wu, Rui Cao, Di Wang, Zhiguang Cao, Xuan Wu, Peng Zhao, Yuanshu Li, You Zhou, Yuan Jiang

Research Collection School Of Computing and Information Systems

The Vehicle Routing Problem (VRP) is a critical combinatorial optimization problem with wide-reaching real-world applications, particularly in logistics, transportation. While neural network-based VRP solvers have shown impressive results on test instances similar to training data, their performance often degrades when faced with varying scales and unseen distributions, limiting their practical applicability. To overcome these limitations, we introduce DGL (Dynamic Global-Local Information Aggregation), a novel model that combines global and local information to effectively solve VRPs. DGL dynamically adjusts local node selections within a localized range, capturing local invariance across problems of different scales and distributions, thereby enhancing generalization. At the …

Rethinking Cognitive Complexity For Unit Tests: Toward A Readability-Aware Metric Grounded In Developer Perception, Wendkûuni C. Ouédraogo, Yinghua Li, Xueqi Dang, Xin Zhou, Anil Koyuncu, Jacques Klein, David Lo, Tegawendé F. Bissyandé

Research Collection School Of Computing and Information Systems

Automatically generated unit tests-from searchbased tools like EvoSuite or LLMs-vary significantly in structure and readability. Yet most evaluations rely on metrics like Cyclomatic Complexity and Cognitive Complexity, designed for functional code rather than test code. Recent studies have shown that SonarSource's Cognitive Complexity metric assigns nearzero scores to LLM-generated tests, yet its behavior on EvoSuitegenerated tests and its applicability to test-specific code structures remain unexplored. We introduce CCTR, a Test-Aware Cognitive Complexity metric tailored for unit tests. CCTR integrates structural and semantic features like assertion density, annotation roles, and test composition patterns-dimensions ignored by traditional complexity models but critical for …

Flow, Immersion, And Presence: Creating Virtual Reality And Engagement In The Era Of Ubiquitous And Intelligent Technologies, Yi Maggie Guo, Fiona Fui-Hoon Nah, Nannan Xi, Marshall Scott Poole

Research Collection School Of Computing and Information Systems

Researchers use the concepts of flow, immersion, and presence to explain the usage of and engagement (e.g., cognitive absorption) with information technology. In this special issue, we showcase four papers on empirical investigations of flow and immersion, their antecedents, and their outcomes. These papers address research questions that range from investigating the antecedents and consequences of immersion in head-mounted displays of virtual reality, designing for the flow experience in extended reality, studying factors influencing user engagement in the metaverse, and identifying adverse effects of work-related flow. We also provide directions and suggestions for future research.

Vibemus: Proactive Agentic System For Music Personalization, Zhiliang Guo, Teng Tu, Yunshan Ma, Xun Yang

Research Collection School Of Computing and Information Systems

Large language models (LLMs) enable diverse forms of AI-assisted creation, yet they often struggle to bridge the preference-articulation gap: users may provide incomplete or vague intentions or lack the vocabulary to specify what they want, yielding outputs misaligned with true preferences. To address this gap and facilitate music creation in a vibe-centric environment, we introduce VibeMus, a proactive agentic system built on open-source components. The system engages in multi-turn dialogue to progressively determine the music’s emotion, genre, lyrics, and other aspects before generation. Simulated evaluations show that proactive clarification improves alignment with users’ intended nuances. Our approach is training-free, leveraging …

Improving Co-Decoding Based Security Hardening Of Code Llms Leveraging Knowledge Distillation, Dong Li, Shanfu Shu, Meng Yan, Zhongxin Liu, Chao Liu, Xiaohong Zhang, David Lo

Research Collection School Of Computing and Information Systems

Large Language Models (LLMs) have been widely adopted by developers in software development. However, the massive pretraining code data is not rigorously filtered, allowing LLMs to learn unsafe coding patterns. Several prior studies have demonstrated that code LLMs tend to generate code with potential vulnerabilities. The widespread adoption of intelligent programming assistants poses a significant threat to the software development process. Existing approaches to mitigating this risk primarily involve constructing secure data that are free of vulnerabilities and then retraining or fine-tuning the models. However, such an effort is resource intensive and requires significant manual supervision. When the model parameters …

Exploring Parameter-Efficient Fine-Tuning Techniques For Code Generation With Large Language Models, Martin Weyssow, Xin Zhou, Kisub Kim, David Lo, Houari A. Sahraoui

Research Collection School Of Computing and Information Systems

Large language models (LLMs) demonstrate impressive capabilities to generate accurate code snippets given natural language intents in a zero-shot manner, i.e., without the need for specific fine-tuning. While prior studies have highlighted the advantages of fine-tuning LLMs, this process incurs high computational costs, making it impractical in resource-scarce environments, particularly for models with billions of parameters. To address these challenges, previous research explored in-context learning (ICL) and retrieval-augmented generation (RAG) as strategies to guide the LLM generative process with task-specific prompt examples. However, ICL and RAG introduce inconveniences, such as the need for designing contextually relevant prompts and the absence …

The Moderating Role Of Trait Online Disinhibition In Exacerbating The Online Victim-Bully Cycle, Sandeeshwara K Tennakoon Appuhamillage Kasturiratna, Andree Hartanto

Research Collection School of Social Sciences

The growth of the internet and social media as a communication platform has increased the incidence of cyberbullying victimisation. While there has been increasing research interest on the antecedents of cyberbullying perpetration, little is known on why some individuals who themself experience cyber victimisation are more likely to become cyberbullying perpetrators. Considering the large number of individuals who experience cyberbullying victimisation in the current, highly digitalised world, this trend of victims turning into bullies poses a worrisome possibility and deserves research attention. One promising individual difference that could potentially moderate the relationship between cyberbullying victimisation can lead to cyberbullying perpetration …

The Moderating Role Of Digital Multi-Sided Platform On The Firm Value Of Traditional Value-Chain Firms, Chee Pheng Lim

Dissertations and Theses Collection (Open Access)

This dissertation examines the strategic value and performance implications for traditional value-chain firms (TVCFs) that adopt digital multi-sided platforms (DMSPs) to augment their existing businesses. DMSPs facilitate interactions among multiple user groups through digital intermediaries, generating self-reinforcing network effects that enhance value creation, reduce operational and transaction costs, and enable collective innovation. Despite the prevalence of platform-based firms, 60% of global unicorns and 7 of the world’s 10 most valuable companies operate digital platforms, empirical research on the value-creation mechanisms of DMSPs remains limited. Anchored in the resource-based view and platform theory, this study investigates how DMSP moderates the relationship …

Transforming The World With Reparations, Ingrid Wuerth Brunk, Monica Hakimi

Vanderbilt Law School Faculty Publications

This special issue of the American Journal of International Law—devoted entirely to reparations in international law—offers a range of perspectives on reparations for large-scale harms relating to colonialism, slavery, industrialization, and transboundary pollution. As the symposium authors describe, the gap between the reparations that justice might demand and the ones that international law provides is enormous. The international law for reparations does not come close to remedying such harms and is not poised to do so anytime soon.

Is There Life In The Ruins? A Look At Post-Sveen Contract Clause Jurisprudence, James W. Ely, Jr.

Vanderbilt Law School Faculty Publications

Seven years ago, in Sveen v. Melin, the Supreme Court applied the prevailing multipart test and rejected a contract clause claim. The result was hardly a surprise. The Court has not invoked the contract clause to invalidate a state law in more than forty years. The decision broke no new ground and seemingly signaled that the Court was content with the current multipart test, one that appears calculated to uphold state regulatory authority rather than vindi- cate the rights of contracting parties. Justice Neil Gorsuch force- fully dissented in Sveen, insisting that the multifactor test "seems hard to square with …

Do Representative Payments Matter?, Brian T. Fitzpatrick, Colton Cronin

Vanderbilt Law School Faculty Publications

For many decades, courts have awarded the representative plaintiffs who bring class actions an extra payment when the actions recover something for the class. It has long been thought that the payments are necessary to induce a class member to step forward and serve as a representative, and, without them, many class actions would go away. Indeed, we show that the payments had become all but ubiquitous in non-securities class actions. In 2020, however, the United States Court of Appeals for the Eleventh Circuit became the only circuit to hold the payments unlawful. We test whether the Eleventh Circuit's decision …

Item 1: Syllabus Hssj 2200: Civic Leadership, Wendy Wagner

Wendy Wagner, Civic Leadership

This is a course in leadership studies that challenges students to consider the leadership development literature in civic contexts. It is also a service-learning course. While service itself is a form of civic participation, it's important to note that service-learning courses don't always focus on issues of civic identity and engagement as much as one might think. Civic learning is not an inherent outcome of all service-learning experiences. The literature in community engaged scholarship is clear that we do not achieve civic learning outcomes from simply adding ten “service hours” to an otherwise unaltered course. Instead, assignments and classroom discussions …
