Interdependence Of Adoption Decisions Of Agroecological Vegetable Cropping Systems Among Smallholder Farmers In Eastern Africa, Essy C. Kirui, Dickson O. Okello, Michael M. Kidoido, Daniel M. Mutyambai, Komivi S. Akutse

All Peer-Reviewed Publications

Vegetable production plays a vital role in enhancing nutrition and generating income in Kenya, where it is an important component of the agricultural sector. Among the most widely grown vegetables are cruciferous crops, while traditional African vegetables have increasingly gained prominence in recent years. Smallholder farmers account for more than 70% of the country’s total vegetable production. However, they face various complex factors such as extreme climate variability, invertebrate pests, and diseases which reduce productivity, yields and household incomes. They, therefore, often resort to the overuse of synthetic fertilizers and pesticides that could increase their susceptibility to pest resistance, declining …

Directing Young Actors, Mitchell Whelan

Theses : Honours

This reflective practice case study examines the studio environment of a small ensemble of female actors aged 16-19, in the rehearsal of a one-act play. Performing arts researchers working in youth spaces commonly adhere to conventions of ethnodrama and facilitate a process in which participants contribute personal stories as performance material. The present paper uses a published text (Slut by Patricia Cornelius) to position participants as actors, rather than devisors who must conjure original material. Through critical reflection, the project assesses the impact of developing performance material slowly while also making time for socialisation between castmates. Drawing on my repertoire …

A Creative Exploration Of Bud Powell's Bebop Vocabulary For Modern Jazz Harmony, Flavio Colonetti

Theses : Honours

This thesis presents a practice-led research (PLR) exploration of adapting Bud Powell's bebop improvisational language for contemporary jazz performance. Through transcription and analysis of Powell's right-hand melodic material, this study employs an iterative framework to identify and transform several core stylistic traits. The initial investigation, focused on creatively transforming two extended melodic phrases, demonstrated success in traditional functional harmonic contexts but revealed a limitation when applied to the more modern, vertical chord progressions.

This prompted a methodological shift to a more modular system, whereby a catalogue of 26 short "Vocabulary Seeds" (VS) drawn from across Powell's discography was created. As …

Moral Outrage To Market Impact: A Multi-Level Analysis Of Corporate Cancel Culture, Sayan Gupta, T. Andrew Poehlman

AMTP Proceedings 2026

Corporate cancel culture is often dismissed as “just social media noise,” but for managers the real stakes show up in markets. This paper develops and tests a three-level framework linking moralized social-media discourse, online brand reputation, and firm-level financial outcomes. Using three canonical cancellations—Dolce & Gabbana’s China controversy, Tesla’s politicization via Elon Musk, and Bud Light’s backlash after its transgender influencer partnership—we first show that these events are organized around spikes in moral-emotional language and structural virality, not generic negativity. We then document how this moral outrage predicts shifts in brand sentiment, associations, and engagement across platforms, before examining corresponding …

Dollar Challenger? Cbdcs, Complexities, And Monetary Hegemony, Heng Wang

Research Collection Yong Pung How School Of Law

Digitalization is transforming the architecture of the international monetary system, reshaping how currencies function and financial infrastructures evolve. Among the significant developments are central bank digital currencies (CBDCs)—new digital forms of national currencies. While CBDCs promise benefits such as efficiency, they also generate relational, technological, legal, and governance complexities that would profoundly affect the global financial landscape. Against this backdrop, a compelling question arises: will CBDCs, particularly cross-border CBDCs, challenge U.S. dollar dominance?

To address this, this Article adopts a forward-looking approach to examine three interrelated crucial questions: what makes CBDCs complex? What governance complexity is likely to arise? Will …

‘Salami Slicing’ And Issue Estoppel: Foreign Decisions On The Governing Law, Adeline Chong

Research Collection Yong Pung How School Of Law

Whether an issue estoppel arises over foreign decisions on the governing law of the claim has not been directly considered by an English court, but decisions in other jurisdictions show that this question is increasingly being raised in litigation. Is there identity of issue if the two courts apply different choice of law rules? The answer turns on whether a broad or narrow framing of the issue is adopted. It is suggested that, absent an issue which is subject to forum international public policy, forum overriding mandatory rules or which is one that the forum court retains the prerogative to …

Hiding An Ear In Plain Sight: On The Practicality And Implications Of Acoustic Eavesdropping With Telecom Fiber Optic Cables, Youqian Zhang, Zheng Fang, Huan Wu, Sze Yiu Chau, Chao Lu, Xiapu Luo

Department of Construction, Environment and Engineering

Optical fibers are widely regarded as reliable communication channels due to their resistance to external interference and low signal loss. This paper demonstrates a critical side channel within telecommunication optical fiber that allows for acoustic eavesdropping. By exploiting the sensitivity of optical f ibers to acoustic vibrations, attackers can remotely monitor sound-induced deformations in the fiber structure and further recover information from the original sound waves. This issue becomes particularly concerning with the proliferation of Fiber-to-the-Home (FTTH) installations in modern buildings. Attackers with access to one end of an optical fiber can use commercially available Distributed Acoustic Sensing (DAS) systems …

Optical Fiber Identification Via 2-D Rayleigh Backscattering Fingerprints, Huan Wu, Fang Zheng, Youqian Zhang, Chao Lu

Department of Construction, Environment and Engineering

We propose an image-assisted optical fiber identification method that exploits the unclonable Rayleigh backscattering signatures measured by optical frequency-domain reflectometry (OFDR). A two-dimensional binary optical fiber identifier (OFID), analogous to a digital fingerprint image, is derived from the Rayleigh backscattering spectrum (RBS) matrix, enabling identification when combined with structure similarity index measure (SSIM). Experiments show that the proposed scheme offers 109% improvement in robustness over conventional one-dimensional local-RBS matching, while reducing data storage from 0.98 MB to 39.6 kB per measurement. A systematic analysis of OFDR parameters reveals that identification accuracy is maximized at a spatial resolution of approximately 3 …

Generalization Bounds For Semi‑Supervised Matrix Completion With Distributional Side Information, Antoine Ledent, Mun Chong Soo, Minh Hieu Nong

Research Collection School Of Computing and Information Systems

We study a matrix completion problem where both the ground truth R matrix and the unknown sampling distribution P over observed entries are low-rank matrices, and share a common subspace. We assume that a large amount M of unlabeled data drawn from the sampling distribution P is available, together with a small amount N of labeled data drawn from the same distribution and noisy estimates of the corresponding ground truth entries. This setting is inspired by recommender systems scenarios where the unlabeled data corresponds to ‘implicit feedback’ (consisting in interactions such as purchase, click, etc. ) and the labeled data …

Thinkmatter: Panoramic-Aware Instructional Semantics For Monocular Vision-And-Language Navigation, Guangzhao Dai, Shuo Wang, Hao Zhao, Bin Zhu, Qianru Sun, Xiangbo Shu

Research Collection School Of Computing and Information Systems

Vision-and-Language Navigation in continuous environments (VLN-CE) requires an embodied robot to navigate the target destination following the natural language instruction. Most existing methods use panoramic RGB-D cameras for 360° observation of environments. However, these methods struggle in real-world applications because of the higher cost of panoramic RGB-D cameras. This paper studies a low-cost and practical VLN-CE setting, e.g., using monocular cameras of limited field of view, which means “Look Less” for visual observations and environment semantics. In this paper, we propose a ThinkMatter framework for monocular VLN-CE, where we motivate monocular robots to “Think More” by 1) generating novel views …

Synergistic Removal Of Microplastic Fibres: Integrating Chitosan Coagulation In Hybrid Water Pre-Treatment Systems, Jayasuriya Arachchilage Nimesha Thathsarani

Theses: Doctorates and Masters

Microplastic fibres (MPFs) are the most prevalent form of microplastics detected in the influents of water and wastewater treatment plants. Owing to their elongated shape and low density, MPFs frequently evade removal even during tertiary processes such as membrane filtration. Enhancing pretreatment, particularly through cost-effective coagulation-flocculation can reduce the treatment burden on downstream systems. However, conventional inorganic coagulants often necessitate high dosages and can leave residual ions, posing environmental concerns.

As a sustainable alternative, the use of environmentally friendly coagulants such as Chitosan has gained attention for MPF removal. While Chitosan exhibits favourable qualities, its practical application is hindered by …

An Investigation Into The Mechanisms, Barriers, Degree And Sphere Of Risk Influence In Corporate Security, Nicola Lockhart

Theses: Doctorates and Masters

This study investigates the sphere of corporate security risk influence within organisations, addressing the conceptual and practical ambiguity surrounding the activity’s capacity to shape organisational decisions, behaviours, and risk priorities. While corporate security’s protective role is widely recognised, its broader organisational risk influence remains under-theorised. The study defines the sphere of risk influence as the range of organisational stakeholders and environments with which the corporate security activity interacts, and within which it may engage, persuade, and mobilise action. This sphere is analytically constituted through the intersection of three dimensions: the mechanisms through which influence is attempted, the barriers that constrain …

Getting Ready Right: The Impact And Influence Of The University Appointed Supervisor, Madlen Griffiths

Theses: Doctorates and Masters

Initial Teacher Education professional experience is a valued component of teacher education courses, where preservice teachers can practise applying what they have learned at university in classroom settings. Key to these experiences are supervisors, who are employed by the university and support these aspiring teachers during their professional experiences. This supervisory role is complex, underrated, under-theorised and under researched. Consequently, this research sought to address this shortfall through an investigation into the perspectives of two of the major stakeholders in these experiences: the preservice teachers and the supervisors.

Adopting a social constructivist methodology, this research examined the stakeholders’ perceptions of …

The Development Of A Midwifery Specific Tool To Identify The Barriers And Enablers To Change Within The Midwifery Setting, Sara Davis

Theses: Doctorates and Masters

Despite being well-positioned to identify service gaps and propose improvements, many midwives lack the knowledge, skills, confidence, or tools to effect practice change. Implementation science (IS) offers a structured approach to moving evidence-based innovations into practice; however, existing IS theories, models, and frameworks do not reflect the unique context of midwifery practice. The first step in the intentional implementation of an evidence-based practice innovation is to conduct a context assessment to identify factors that may facilitate or impede its uptake. There are numerous evidence-based checklists for this, but none capture all the influences on midwifery practice environments.

In this study, …

Learning-Based Graph Shrinking For Quantum Optimization Of Constrained Combinatorial Problems, Monit Sharma, Hoong Chuin Lau

Research Collection School Of Computing and Information Systems

Graph shrinking has recently emerged as a powerful preprocessing technique for hybrid classical–quantum optimization, enabling variable and constraint reduction before quantum solving. Conventional approaches rely on Semi-Definite Programming (SDP) relaxations to compute vertex correlations, but these methods suffer from high computational overhead, instance-specific tuning, and limited generalizability. In this work, we replace the handcrafted SDP correlation stage with a reinforcement learning (RL) based correlation estimator, trained to predict merge quality directly from graph structure. We reformulate the graph shrinking process as a Markov Decision Process (MDP), design a Graph Neural Network (GNN) policy to guide vertex merging, and integrate the …

Security-Enhanced Decentralized Conditional Privacy-Preserving Authentication In Vanets, Suqin Luo, Xinghua Li, Yinbin Miao, Xuelin Cao, Zhan Zhang, Yunwei Wang, Deng R.H.

Research Collection School Of Computing and Information Systems

To ensure the legitimacy of communicators while ad dressing the privacy concerns of vehicles in vehicular ad-hoc networks (VANETs), conditional privacy-preserving authentication (CPPA) schemes have been proposed. Given that existing schemes suffer from single point of failure due to centralized authorities, several distributed CPPA schemes have been proposed. However, these schemes all ignore the tight cementation between system secret keys and the authority, which could be a serious threat to system security, that the compromised authority may leak the system secret key. To address these issues, we propose a security enhanced decentralized conditional privacy-preserving authentication (DCPPA) scheme. DCPPA first introduces …
