The Relationship Between Academic Crafting, Work-School Facilitation And Academic Engagement: A Mediated Model, Gökhan Kerse, Umut Çil

Makara Human Behavior Studies in Asia

This research examines the relationship between academic crafting, work-school facilitation and academic engagement in higher education. Based on the Job Demands-Resources (JD-R) Model, the research sought to determine how students' alignment of academic activities with personal preferences and interests (academic crafting) affects academic engagement and whether work-school facilitation mediates this effect. The research therefore emphasized the delicate balance that students strike between their work obligations and their scholarly activities. Our research hypotheses focused on understanding how academic crafting directly and indirectly affects student engagement. The research data were obtained from a sample of students enrolled in postgraduate programs and actively …

Recommendations For The Revision Of Animal Units And Their Application In The Western Australian Rangelands, Ian Mclean, Sally Finch

Natural resources commissioned reports

This report provides recommendations for the practical application of a methodology for calculating and applying Animal Units in the rangelands of Western Australia.

Animal Units have evolved over time, in their definition, derivation and the size of the standard animals used. This has resulted in their being varying and inconsistent approaches within and across jurisdictions which has limited their application.

The Animal Unit methodology applied in this report is used in other rangeland and pastoral regions, it therefore progresses a nationally consistent approach.

The standard animals used in this methodology are:

• Animal Equivalent (AE), a 450 kg Bos taurus steer …

Can A Tobin Tax Curb Speculation In The Housing Market? A Study On The Effect In The Primary Market Of Hong Kong Tax Policy, Dinh Tuan Dang

Dissertations and Theses Collection (Open Access)

This study examines the effect of Special Stamp Duty (SSD) and Buyer's Stamp Duty (BSD) on Hong Kong’s housing prices in the primary market. Using micro transaction data, I show that the Tobin tax policies were not effective in cooling the primary market. The primary market responded differently when facing the two events. Specifically, SSD Phase 1 led to a 9.4% price increase within 6 to 12 months post-implementation, suggesting a lag effect. The introduction of SSD Phase 2 and BSD initially caused a significant 13.1% price surge in the first 6 months, but was followed by a notable 9% …

Health Insurance And The Rise Of Women: Evidence From The New Cooperative Medical Scheme, Xingyu Bai

Dissertations and Theses Collection (Open Access)

Females are traditionally viewed as the primary providers of informal parental care in China, especially in rural areas. We investigate whether health insurance coverage in rural China, the New Cooperative Medical Scheme (NCMS), can unleash more female labor force participation by reducing the burden of informal parental care. Employing a heterogeneity-robust difference-in-differences estimation, we find that the NCMS has a significant positive impact on female labor supply, primarily in non-farm occupations. In contrast, we observe no significant changes in male labor supply. We explore the mechanism by showing that the NCMS significantly decreases both the provision and demand for parental …

Study On The Structural Influence Mechanism Of Robot Construction On Real Estate Project Costs: Moderating Effect Of Management Change, Xiujuan Wei

Dissertations and Theses Collection (Open Access)

Cost control in construction is crucial for the survival of real estate enterprises. Especially in the context of cyclical downturns in the real estate industry, it is essential to achieve cost reduction and efficiency improvement in real estate projects. Currently, the widespread application of robotics technology may hold the key to achieving this goal. Robotics technology is widely recognized for its ability to automate tasks and reduce labor costs. However, it also brings about transformative impacts on management, organization, production, and processes, which can paradoxically increase project costs. Unfortunately, there is a lack of research focusing on the impact of …

Transportation, Healthcare Seeking, And Outcomes, Xiao Lin Ong

Dissertations and Theses Collection (Open Access)

Advancements in engineering and transportation technology have integrated commuting into modern living. Most studies on transportation infrastructure, such as roads and railways, focus on economic outcomes. This paper examines an overlooked outcome of transportation connectivity: access to medical care. We study the role transportation networks play in determining patients’ treatment location choices. Specifically, we aim to study 1) why patients travel to begin with, 2) how do patients choose where to go for treatment, and 3) how travel times can affect patients’ travel decisions. To do so, we develop a dynamic discrete choice, spatial model and provide empirical estimates. We …

Executive Function And Feedback In Regulatory Monitoring: Towards An Understanding Of Flexible And Adaptive Emotion Regulation, Gilaine Rui Ng

Dissertations and Theses Collection (Open Access)

Monitoring is a process which involves attending to feedback regarding the efficacy of ongoing regulatory strategies and determining whether to switch or maintain strategies (i.e., strategy switching or maintenance) in order to maximize adaptive outcomes. While conceptual accounts underscore the critical role of monitoring in flexible and adaptive emotion regulation, empirical research remains scarce, and the cognitive factors which subserve the monitoring process remain unclear and poorly understood. To bridge this gap, we investigate how components of executive function (EF)—a set of cognitive control processes necessary for flexible, goal-directed behavior—would differentially support the monitoring process. Additionally, we examine the extent …

Microstructural Evolution In A Precipitate-Hardened (Fe0.3ni0.3mn0.3cr0.1)94ti2al4 Multi-Principal Element Alloy During High-Pressure Torsion, Matthew Luebbe, Jiaqi Duan, Peipei Cao, Zhaoping Lu, Rinat K. Islamgaliev, Ruslan Z. Valiev, Yuzi Liu, Haiming Wen

Materials Science and Engineering Faculty Research & Creative Works

Multi-principal element alloys demonstrate high strength, thermal stability, and irradiation resistance, making them excellent candidate materials for applications in nuclear reactors and other harsh environments. Some studies have examined the use of high-pressure torsion to strengthen MPEAs through grain size reduction and strain hardening. However, no studies have investigated the effect of HPT on secondary phases (precipitates) within an MPEA. Two alloys, (Fe_0.3Ni_0.3Mn_0.3Cr_0.1)₉₄Ti₂Al₄ containing Ni(Ti, Al) B2 phase, and CrFe σ phase, and single-phase Fe_0.3Ni_0.3Mn_0.3Cr_0.1, were fabricated by casting …

Eighth-Order Foldy-Wouthuysen Transformation, Ulrich D. Jentschura

Physics Faculty Research & Creative Works

The calculation of higher-order binding corrections to bound systems is a fundamental problem of theoretical physics. For any nonrelativistic expansion, one needs the Foldy-Wouthuysen transformation, which disentangles the particle and the antiparticle degrees of freedom. This transformation is carried out here to eighth order in the momenta or to eighth order in the momentum operators, which is equivalent to the eighth order of the fine-structure constant. Matrix elements of the eighth-order terms are evaluated for F_5/2 and F_7/2 states in hydrogenlike ions and compared with the Dirac-Coulomb energy levels.

Tunneling Dynamics Of 164dy Supersolids And Droplets, S. I. Mistakidis, K. Mukherjee, S. M. Reimann, H. R. Sadeghpour

Physics Faculty Research & Creative Works

The tunneling dynamics of a magnetic Dy164 quantum gas in an elongated or pancake skewed double-well trap is investigated with a time-dependent extended Gross-Pitaevskii approach. Upon lifting the energy offset, different tunneling regimes can be identified. In the elongated trap and for sufficiently large offset, the different configurations exhibit collective macroscopic tunneling. For smaller offset, partial reflection from and transmission through the barrier lead to density accumulation in both wells, and eventually to tunneling locking. One can also reach the macroscopic self-trapping regime for increasing relative dipolar interaction strength, while tunneling vanishes for large barrier heights. A richer dynamical behavior …

Critical Behavior And Collective Modes At The Superfluid Transition In Amorphous Systems, Pulloor Kuttanikkad Vishnu, Martin Puschmann, Rajesh Narayanan, Thomas Vojta

Physics Faculty Research & Creative Works

We investigate the critical behavior and the dynamics of the amplitude (Higgs) mode close to the superfluid-insulator quantum phase transition in an amorphous system (i.e., a system subject to topological randomness). In particular, we map the two-dimensional Bose-Hubbard Hamiltonian defined on a random Voronoi-Delaunay lattice onto a (2+1)-dimensional layered classical XY model with correlated topological disorder. We study the resulting model by laying recourse to classical Monte Carlo simulations. We specifically focus on the scalar susceptibility of the order parameter to study the dynamics of the amplitude mode. To do so, we harness the maximum entropy method to perform the …

Reading The Candlesticks: An Ok Estimator For Volatility, Jia Li, Dishen Wang, Qiushi Zhang

Research Collection School Of Economics

We propose an Optimal candlesticK (OK) estimator for the spot volatility using high-frequency candlestick observations. Under a standard infill asymptotic setting, we show that the OK estimator is asymptotically unbiased and has minimal asymptotic variance within a class of linear estimators. Its estimation error can be coupled by a Brownian functional, which permits valid inference. Our theoretical and numerical results suggest that the proposed candlestick-based estimator is much more accurate than the conventional spot volatility estimator based on high-frequency returns. An empirical illustration documents the intraday volatility dynamics of various assets during the Fed chairman's recent congressional testimony.

Bubbly Booms And Welfare, Feng Dong, Yang Jiao, Haoning Sun

Research Collection School Of Economics

We show the competing effects of a housing bubble on the real economy by developing a multi-sector dynamic model with housing production. On the one hand, firms can sell or collateralize their housing, so a housing bubble helps firms obtain credit to finance their investment and expand production. On the other hand, a boom in the housing sector crowds out labor in the non-housing sector. We show that housing booms can reduce social welfare both in the steady state and in the transitional dynamics only when the production externalities in the non-housing sector are sufficiently large. We quantitatively evaluate our …

Rank-Guaranteed Auctions, Wei He, Jiangtao Li, Weijie Zhong

Research Collection School Of Economics

We propose a combinatorial ascending auction that is “approximately” optimal, requiring minimal rationality to achieve this level of optimality, and is robust to strategic and distributional uncertainties. Specifically, the auction is rankguaranteed, meaning that for any menu M and any valuation profile, the ex-post revenue is guaranteed to be at least as high as the highest revenue achievable from feasible allocations, taking the (|M| + 1)th-highest valuation for each bundle as the price. Our analysis highlights a crucial aspect of combinatorial auction design, namely, the design of menus. We provide simple and sufficient menus in various settings.

Coarse Revealed Preference, Gaoji Hu, Jiangtao Li, John K-H Quah, Rui Tang

Research Collection School Of Economics

We propose a novel concept of rationalization, called coarse rationalization, tailored for the analysis of datasets where an agent’s choices are imperfectly observed. We characterize those datasets which are rationalizable in this sense and present an efficient algorithm to verify the characterizing condition. We then demonstrate how our results can be applied through a duality approach to test the rationalizability of datasets with perfectly observed choices but imprecisely observed linear budget sets. For datasets that consist of both perfectly observed feasible sets and choices but are inconsistent with perfect rationality, our results could be used to measure the extent to …

Two Essays On Asset Prices Around Securities Class Action Lawsuits, Sounak Saha

Theses and Dissertations in Business Administration

Essay 1: Prior studies on securities class action lawsuits have found that there are large negative abnormal returns and an increase in short-selling activity in the days preceding the lawsuit filing. These findings have largely been attributed to anticipatory inference and private information. However, our analysis of a large sample spanning 2009-2019 reveals that more than half of the lawsuits had a public announcement about the law firm investigation in the days leading up to the lawsuit filing. Strikingly, we find that the average cumulative abnormal return during the 10-day pre-filing period was: (1) over -17% for lawsuits with a …

Leveraging Blockchain For Trust Enhancement In Decentralized Marketplaces: A Reputation System Perspective, Meshari Mohammd Aljohani

Computer Science Theses & Dissertations

Centralized marketplaces provide reliable reputation services through a central authority, but this raises concerns about single points of failure, user privacy, and data security. Decentralized marketplaces have emerged to address these issues by enhancing user privacy and transparency and eliminating single points of failure. However, decentralized marketplaces face the challenge of maintaining user trust without a centralized authority. Current blockchain-based marketplaces rely on subjective buyer feedback. Additionally, the transparency in these systems can deter honest reviews due to fear of seller retaliation. To address these issues, we propose a trust and reputation system using blockchain and smart contracts. Our system …

A Landscape Evaluation Of Caffeine Citrate Availability And Use In Newborn Care Across Five Low- And Middle-Income Countries, Osayame Ekhaguere, Olufunke Bolaji, Helen Nabwera, Andrew Storey, Nicholas Embleton, Stephen Allen, Zelalem Demeke, Olufunke Fasawe, Betty Wariari, Mansharan Seth

Centre of Excellence in Women and Child Health

Apnoea of prematurity (AOP) is a common complication among preterm infants (< 37 weeks gestation), globally. However, access to caffeine citrate (CC) that is a proven safe and effective treatment in high-income countries is largely unavailable in low- and-middle income countries, where most preterm infants are born. Therefore, the overall aim of this study was to describe the demand, policies, and supply factors affecting the availability and clinical use of CC in LMICs. A mixed methods approach was used to collect data from diverse settings in LMICs including Ethiopia, Kenya, Nigeria, South Africa, and India. Qualitative semi-structured interviews and focus group discussions were conducted with 107 different health care providers, and 21 policymakers and other stakeholders from industry. Additional data was collected using standard questionnaires. A thematic framework approach was used to analyze the qualitative data and descriptive statistics were used to summarize the quantitative data. The findings indicate that there is variation in in-country policies on the use of CC in the prevention and treatment of AOP and its availability across the LMICs. As a result, the knowledge and experience of using CC also varied with clinicians in Ethiopia having no experience of using it while those in India have greater knowledge and experience of using it. This, in turn, influenced the demand, and our findings show that only 29% of eligible preterm infants are receiving CC in these countries. There is an urgent need to address the multilevel barriers to accessing CC for managing AOP in Africa. These include cost, lack of national policies, and, therefore, lack of demand stemming from its clinical equivalency with aminophylline. Practical ways to reduce the cost of CC in LMICs could potentially increase its availability and use.
