A Network Analysis Of The Singapore Court Of Appeal’S Citations To Precedent, Jerrold Tsin Howe Soh

Research Collection Yong Pung How School Of Law

This article presents findings from an empirical network analysis of citation practices in Singapore's highest court.A network of all 987 reported Court of Appeal judgments handed down from 2000 to 2017 is constructed. Networkcentrality algorithms are used to rank judgments by centrality. Judgments on contract law, particularly on contractual interpretation and terms, emerge as the most central. Based on this, this article argues that more attention can be paid to interpretation per se as a legal skill. More generally, this article establishes a framework for applying network analysis to Singapore jurisprudence on a larger scale.

A Hardware-Deployable Neuromorphic Solution For Encoding And Classification Of Electronic Nose Data, Anup Vanarse, Alexander Rassau, Peter Van Der Made

Research outputs 2014 to 2021

In several application domains, electronic nose systems employing conventional data processing approaches incur substantial power and computational costs and limitations, such as significant latency and poor accuracy for classification. Recent developments in spike-based bio-inspired approaches have delivered solutions for the highly accurate classification of multivariate sensor data with minimized computational and power requirements. Although these methods have addressed issues related to efficient data processing and classification accuracy, other areas, such as reducing the processing latency to support real-time application and deploying spike-based solutions on supported hardware, have yet to be studied in detail. Through this investigation, we proposed a spiking …

Biodiversity Offsets In Eia: Getting The Timing Right, Marlene De Witt, Jenny Pope, Francois Retief, Alan Bond, Angus Morrison-Saunders, Carli Steenkamp

Research outputs 2014 to 2021

Major developments can result in significant impacts on biodiversity, which the mandated process of environmental impact assessment (EIA) aims to mitigate. There has been a recent move towards the application of biodiversity offsets as a last-resort, compensatory measure when options at the earlier stages in the mitigation hierarchy of avoidance, minimisation and restoration have been exhausted. Guidance on biodiversity offset planning available in different jurisdictions, however, demonstrates a lack of consensus about when biodiversity offsets should be formally introduced into the EIA process, and previous research has highlighted the perceived risks associated with commencing detailed offset planning too early as …

Research outputs 2014 to 2021

Climate change and human pressures are changing the global distribution and the extent of intermittent rivers and ephemeral streams (IRES), which comprise half of the global river network area. IRES are characterized by periods of flow cessation, during which channel substrates accumulate and undergo physico‐chemical changes (preconditioning), and periods of flow resumption, when these substrates are rewetted and release pulses of dissolved nutrients and organic matter (OM). However, there are no estimates of the amounts and quality of leached substances, nor is there information on the underlying environmental constraints operating at the global scale. We experimentally simulated, under standard laboratory …

Research outputs 2014 to 2021

Policies aiming to preserve vegetated coastal ecosystems (VCE; tidal marshes, mangroves and seagrasses) to mitigate greenhouse gas emissions require national assessments of blue carbon resources. Here, we present organic carbon (C) storage in VCE across Australian climate regions and estimate potential annual CO₂ emission benefits of VCE conservation and restoration. Australia contributes 5–11% of the C stored in VCE globally (70–185 Tg C in aboveground biomass, and 1,055–1,540 Tg C in the upper 1 m of soils). Potential CO₂ emissions from current VCE losses are estimated at 2.1–3.1 Tg CO₂-e yr^-1, increasing annual CO …

Performance Analysis Of A Thermal-Driven Tubular Direct Contact Membrane Distillation System, Abdellah Sharifian, Mehdi Khiadani, Ataollah Nosrati

Research outputs 2014 to 2021

This paper examines the performance of a thermal-driven tubular direct contact membrane distillation (DCMD) system theoretically and experimentally. A multi-step mathematical model was developed to predict the freshwater productivity of the tubular DCMD module applicable for both small and large-scale applications by considering the changes in the operational variables along the membrane’s length. The proposed model was verified by building an experimental rig which was tested under different operational conditions. The results showed that keeping the mass flow rates in the hot and cold channels either near the end or beyond the transition range of the flows results in higher …

Teachers’ Perspectives On The Identification Of, And Provisions For, Gifted And Talented English As An Additional Language Students, Lucy Byramji Hands

Theses: Doctorates and Masters

In recent years, Western Australian State schools have seen a sharp rise in the number of students who use English as an Additional Language (EAL). Almost one-third of them have been identified as having culturally and linguistically diverse ancestry (Australian Bureau of Statistics, 2016). Many are gifted and talented (GT). However, while it has been widely acknowledged that GT abilities can be found in all ethnic, cultural, and linguistic groups, barriers such as socioeconomic circumstances, stereotypes, political climate, language backgrounds and a myriad of factors can influence the recognition, identification and full participation of EAL students in gifted and talented …

Video Cued Teacher Reflection To Guide Enhancement Of Student Engagement In A Specialist Primary Classroom, Tamara Nicole Standley

Theses: Doctorates and Masters

Specialist primary teachers confront the challenging task of teaching extensive learning content of the Western Australian Curriculum, within limited weekly timetabled lessons. This was the motivating factor behind this study aimed at investigating the use of self-tracking video technology as a tool for teacher reflection, to guide enhancement of student engagement and learning in the specialist classroom. Reflective practice is integral to monitoring and improving teaching pedagogy but without an effective reflection tool, it can potentially be a waste of time.

The capacity for a teacher to engage in reflection-on-action through real time video analysis enables a deeper understanding of …

Recent Developments In Distribution Theory: A Brief Survey And Some New Generalized Classes Of Distributions, Zubair Ahmad, Gholamhossein G. Hamedani, Nadeem Shafique Butt

Mathematical and Statistical Science Faculty Research and Publications

The generalization of the classical distributions is an old practice and has been considered as precious as many other practical problems in statistics. These generalizations started with the introduction of the additional location, scale or shape parameters. In the last couple of years, this branch of statistics has received a great deal of attention and quite a few new generalized classes of distributions have been introduced. We present a brief survey of this branch and introduce several new families as well.

Breath Practices For Survivor And Caregiver Stress, Depression, And Post- Traumatic Stress Disorder: Connection, Co-Regulation, Compassion, Patricia L. Gerbarg, Richard P. Brown, Chris C. Streeter, Martin Katzman, Monica Vermani

NYMC Faculty Publications

Does compassion itself benefit the healing process or does the activation of neurophysiological processes, from which the experience of compassion arises, trigger a cascade of physical and psychological changes that support health and well-being? Exploration of the neurological substrates of compassion reveals multiple healing pathways that can be activated by mind-body practices. Furthermore, these pathways affect physical health, emotion regulation, and how we perceive and relate to others.

Physiological states affect the capacity for empathy, compassion and understanding. A state of calm alertness based on sympatho-vagal balance may support such high-level prosocial functions. Evidence suggests that polyvagal-informed mind-body practices, particularly …

Circadian Rhythm Phase Shifts Caused By Timed Exercise Vary With Chronotype In Young Adults, J. Matthew Thomas

Theses and Dissertations--Kinesiology and Health Promotion

The circadian system controls 24-hour cycles of behavior and physiology, such as rest-activity and feeding rhythms. The human circadian system synchronizes with, or entrains to, the light/dark cycle (sunrise/sunset) to promote activity and food consumption during the day and rest at night. However, strict work schedules and nighttime light exposure impair proper entrainment of the circadian system, resulting in chronic circadian misalignment. Numerous studies have shown that chronic circadian misalignment results in poor health. Therefore, therapeutic interventions that could shift circadian rhythms and alleviate circadian misalignment could broadly impact public health. Although light is the most salient time cue for …

Effects Of Curcumin And Fenugreek Soluble Fiber Supplements On Submaximal And Maximal Aerobic Performance Indices In Untrained College-Aged Subjects, Jensen Goh Zhong Sheng

Theses and Dissertations--Kinesiology and Health Promotion

Submaximal exercise performance is, in part, limited by the accumulation of metabolic byproducts and energy system capacities. Curcumin and the combination of curcumin and fenugreek soluble fiber (CurQfen^®) have been shown to increase endogenous antioxidants and metabolic byproduct clearance as well as reduce inflammation and lipid peroxidation, and therefore, may enhance submaximal aerobic thresholds. In addition, there is evidence that the galactomannan component of fenugreek, used to enhance bioavailability of curcumin, may also have potential physiological effects related to the up regulation of free fatty acid oxidation Therefore, the purpose of this study was to examine the effects …

Women Into Advanced Manufacturing: Can Community College Open This Door?, Carissa Bradley Schutzman

Theses and Dissertations--Educational Policy Studies and Evaluation

Women still rarely choose to seek employment in advanced manufacturing. Lack of familiarity with manufacturing jobs and education programs, lack of role models, and too few experiential opportunities contribute to women not choosing manufacturing jobs as well as other jobs traditionally held by men (Reha, Lufkin, & Harrison, 2009; St. Rose & Hill, 2013; Starobin & Laanan, 2008). Nontraditional jobs for women often provide higher wages and more opportunity for advancement than traditional jobs for women. This study is a qualitative thematic narrative analysis of factors that influenced women who chose an advanced manufacturing program at a community college to …

A Partial Simulation Study Of Phantom Effects In Multilevel Analysis Of School Effects: The Case Of School Socioeconomic Composition, Hao Zhou

Theses and Dissertations--Education Sciences

Socioeconomic status (SES) affects students’ academic achievement at different levels of an educational system. However, misspecified Hierarchical Linear Model (HLM) may bias school SES estimation. In this study, a partial simulation study was conducted to examine how misspecified HLM model bias school and student SES estimation.

The result of this study can be summarized by four important points. First, based on partial simulation procedure, phantom effects of school SES and student SES are real. Second, characteristics of phantom effects are generalized. The stronger the correlation between prior science achievement measure and present science achievement measure, the greater the decrease in …

Assessing The Model Fit Of Multidimensional Item Response Theory Models With Polytomous Responses Using Limited-Information Statistics, Caihong Rosina Li

Theses and Dissertations--Education Sciences

Under item response theory, three types of limited information goodness-of-fit test statistics – M₂, M_ord, and C₂ – have been proposed to assess model-data fit when data are sparse. However, the evaluation of the performance of these GOF statistics under multidimensional item response theory (MIRT) models with polytomous data is limited. The current study showed that M₂ and C₂ were well-calibrated under true model conditions and were powerful under misspecified model conditions. M_ord were not well-calibrated when the number of response categories was more than three. RMSEA₂ and RMSEA_C2 are …

The Effect Of Increased Physical Activity On Academic Performance, Lauren Michelle Willis

Theses and Dissertations--Education Sciences

Increased levels of obesity, particularly among American youth, have consistently been cause for concern over the last few decades. Additionally, the amount of time youth spend being active throughout the day has consistently decreased. Physical activity levels among school-aged children in America are effected by any number of reasons, but this study points to the possibility of time spent being physically active during the school day having the greatest effect on a student’s overall level of physical activity. Increased pressures from different entities on local schools to improve student performance on standardized test scores have contributed to a decline in …
