The Antecedents, Consequences, And Mediating Role Of Workload Among Chinese Courier Drivers, Haitao Wen, Hongduo Sun, Sebastian Kummer, Ben Farr-Wharton, David M. Herold

Research outputs 2014 to 2021

The growth of e-commerce in China can be regarded as a significant factor in the increase in occupational stress and the voluntary turnover of courier drivers. This paper aims to investigate selected occupational stress factors behind the turnover intentions of Chinese courier drivers. Using data from 229 couriers employed at the largest delivery companies in China, this study applies structural equation modelling to investigate not only the direct relationships between job-stress factors and turnover intentions but also the extent to which workload indirectly mediates turnover intentions among couriers. The results indicate that a combination of high workload with social stressors …

Hydrogen Underground Storage Efficiency In A Heterogeneous Sandstone Reservoir, Doaa Saleh Mahdi, Emad A. Al-Khdheeawi, Yujie Yuan, Yihuai Zhang, Stefan Iglauer

Research outputs 2014 to 2021

Underground hydrogen storage has been recognized as a key technology for storing enormous amounts of hydrogen, thus aiding in the industrial-scale application of a hydrogen economy. However, underground hydrogen storage is only poorly understood, which leads to high project risk. This research thus examined the effect of caprock availability and hydrogen injection rate on hydrogen recovery factor and hydrogen leakage rate to address some fundamental questions related to underground hydrogen storage. A three dimensional heterogeneous reservoir model was developed, and the impact of caprock and hydrogen injected rate on hydrogen underground storage efficiency were analysed with the model. The results …

Extraterritoriality Of Chinese Law: Myths, Realities And The Future, Zhengxin Huo, Man Yip

Research Collection Yong Pung How School Of Law

While China strongly opposes the US practice of ‘long-arm jurisdiction’, it has decided to build its own legal system of extraterritoriality. This paradox reflects the crossroads at which China finds itself currently. Being a country weaker than the sole global superpower, it needs to stand firmly against the American ‘legal bullyism’ by invoking the shield of territorial sovereignty. Yet, as an emerging world power, it is in China’s interest to establish a legal system of extraterritoriality to safeguard its own national interests that extend globally. This article has two aims. First, it provides a comprehensive overview of the current model …

Die Finanzierung Der Nachhaltigkeitsziele: Welche Rolle Spielen Handels- Und Investitionsabkommen?, Stefanie Schacherer

Research Collection Yong Pung How School Of Law

The relationship between foreign direct investment (FDI) and sustainable development is controversial. Studies on the concrete benefits of FDI for sustainable development have not yielded clear results. Nevertheless, sustainable development is central to the ongoing reform process of international investment law. Ideally, international investment agreements (IIAs) should promote the Sustainable Development Goals (SDGs). In any case, IIAs should not undermine national implementation of the SDGs. The following analysis and conceptualization of current developments and legal standards for international investment law will be presented.

'Good Administration' And The 'Good': The Normative Foundation For The Protection Of Legitimate Expectations, Wei Yao, Kenny Chng

Research Collection Yong Pung How School Of Law

An idea that has gained significant traction in both case law and academic commentary as a justification for the protection of legitimate expectations is the concept of ‘good administration’. Going beyond the usual criticisms of the concept’s ambiguity, this article aims to highlight an additional set of difficulties with the invocation of ‘good administration’ as the normative justification for the doctrine. This article’s central argument is that the concept of ‘good’ invoked by the idea of ‘good administration’ inevitably falls to be substantiated by a particular conception of what the ‘good’ requires as a matter of political philosophy. And given …

On 15 December 2021, the Ministry of Finance introduced a new package of measures designed to cool the residential property market. The measures include increases in Additional Buyer’s Stamp Duty (“ABSD”), the tightening of the Total Debt Servicing Ratio, adjustments to the Loan to Valuation limit for loans from HDB and a planned increase of housing supply.Notably, there were significant increases in the ABSD rates applicable to almost all categories of buyers. The ABSD rates only remained unchanged for Singapore Citizens and Permanent Residents purchasing their first residential property (0% and 5% respectively). This article focuses on the implications of …

Reconceptualising Fiduciary Regulation In Actual Conflicts, Man Yip, Kelvin Low

Research Collection Yong Pung How School Of Law

Tis article reviews the fiduciary duty to avoid actual conflicts. It argues that the duty to avoid actual conflicts adds limited substantive value to fiduciary accountability. Its present form has also contributed to widespread misconception of what should be expected of an unfortunate fiduciary who finds themselves in such a position. In this respect, we propose that many of the modern scenarios involving actual conflicts of duties or conflicts of duties and interests are better analysed not in terms of conflict avoidance but in terms of conflict management. Our analysis paves the way for thoughtfully working out what the fiduciaries’ …

Scope Of Duty, Counterfactual Analysis And Birth Defects: The Challenging Case Of Khan V Meadows, Kee Yang Low, Jordan Ting Xuan Chia

Research Collection Yong Pung How School Of Law

The tort of negligence has evolved into a sophisticated and calibrated framework. Even then, aspects of this elaborate structure are constantly being tweaked and, sometimes, challenged. Most recently, in the UKSC decision of Khan v Meadows, the spotlight is thrown on scope of duty analysis against the challenging backdrop of medical negligence and unwanted birth defects. The judgment of the majority suggests there is more that needs to be considered at the stage of damages, and that the sequential framework of negligence may benefit from some rearrangement.

Transformative Governance Of Biodiversity: Insights For Sustainable Development, J. Visseren-Hamakers Ingrid, Jona Razzaque, Pamela Mcelwee, Esther Turnhout, Eszter Kelemen, Graciela M. Rusch, Álvaro Fernández-Llamazares, Ivis Chan, Michelle Mei Ling Lim, Et Al.

Research Collection Yong Pung How School Of Law

While there is much debate on transformative change among academics and policymakers, the discussion on how to govern such change is still in its infancy. This article argues that transformative governance is needed to enable the transformative change necessary for achieving global sustainability goals. Based on a literature review, the article unpacks this concept of transformative governance. It is: integrative, to ensure local solutions also have sustainable impacts elsewhere (across scales, places, issues and sectors); inclusive, to empower those whose interests are currently not being met and represent values embodying transformative change for sustainability; adaptive, enabling learning, experimentation, and reflexivity, …

The Sun In Its Glory: The Diffusion Of Jonathan Dymond’S Works In The United States, 1831-1836, Jennifer Rycenga

Faculty Research, Scholarly, and Creative Activity

The English Quaker and linen-draper Jonathan Dymond (1796-1828) is best known for his strong philosophic articulation of the testimony against war. The first American edition of Dymond’s work, though, was published not by Quakers but by a small group of activist-thinkers in north-eastern Connecticut, the Windham County Peace Society, which issued a thousand copies of Dymond’s The Applicability of the Pacific Principles of the New Testament to the Conduct of States in the spring of 1832. Dymond’s systematic moral philosophy extended into many corners of the burgeoning philanthropic movements in New England, most notably among Immediate Abolitionists, within the Peace …

Advances in computational neuroimaging techniques have expanded the armamentarium of imaging tools available for clinical applications in clinical neuroscience. Non-invasive, in vivo brain MRI structural and functional network mapping has been used to identify therapeutic targets, define eloquent brain regions to preserve, and gain insight into pathological processes and treatments as well as prognostic biomarkers. These tools have the real potential to inform patient-specific treatment strategies. Nevertheless, a realistic appraisal of clinical utility is needed that balances the growing excitement and interest in the field with important limitations associated with these techniques. Quality of the raw data, minutiae of the …

Northern Bobwhite Occupancy Patterns On Multiple Spatial Scales Across Arkansas, Ellery V. Lassiter, Marcus Asher, Grace Christie, Connor Gale, Andrhea Massey, Cody Massery, Christopher R. Middaugh, John T. Veon, Brett A. Degregorio

Biological Sciences Faculty Publications and Presentations

Northern bobwhite Colinus virginianus populations have been rapidly declining in the eastern, central, and southern United States for decades. Land use change and an incompatibility between northern bobwhite resource needs and human land use practices have driven declines. Here, we applied occupancy analyses on two spatial scales (state level and ecoregion level) to more than 5,000 northern bobwhite surveys conducted over 6 y across the entire state of Arkansas to explore patterns in occupancy and land use variables, and to identify priority areas for management and conservation. At the state level, northern bobwhite occupied 29% of sites and northern bobwhite …

Peer Irrigators And The Choice Of Field Management And Water Control Practices For Irrigation In Arkansas, Victoria Bailey, Kent Kovacs, Christopher Henry, Qiuqiong Huang, Larry J. Krutz

Agricultural Economics and Agribusiness Faculty Publications and Presentations

We examined how irrigation techniques in use by family and friends influence the use and share of land utilizing different irrigation techniques by Arkansas producers. A bivariate sample selection model simultaneously estimated how farm characteristics determine the use and explain the share of a farm that utilizes an irrigation technique. We found that the irrigation techniques in use by family and friends do affect the irrigation techniques a producer uses and the share of acres utilizing different irrigation techniques. A producer with a family or friend that uses end-blocking irrigation is 41% more likely to use end-blocking themselves. Having a …

Conditional Wasserstein Generative Adversarial Networks Applied To Acoustic Metamaterial Design, Peter Lai, Feruza Amirkulova, Peter Gerstoft

Faculty Research, Scholarly, and Creative Activity

This work presents a method for the reduction of the total scattering cross section (TSCS) for a planar configuration of cylinders by means of generative modeling and deep learning. Currently, the minimization of TSCS requires repeated forward modelling at considerable computer resources, whereas deep learning can do this more efficiently. The conditional Wasserstein generative adversarial networks (cWGANs) model is proposed for minimization of TSCS in two dimensions by combining Wasserstein generative adversarial networks with convolutional neural networks to simulate TSCS of configuration of rigid scatterers. The proposed cWGAN model is enhanced by adding to it a coordinate convolution (CoordConv) layer. …

The Weaker Sex: Male Lingcod (Ophiodon Elongatus) With Blue Color Polymorphism Are More Burdened By Parasites Than Are Other Sex–Color Combinations, Chelsea L. Wood, Katie L. Leslie, Alanna Greene, Laurel S. Lam, Bonnie Basnett, Scott L. Hamilton, Jameal F. Samhouri

Faculty Research, Scholarly, and Creative Activity

The unusual blue color polymorphism of lingcod (Ophiodon elongatus) is the subject of much speculation but little empirical research; ~20% of lingcod individuals exhibit this striking blue color morph, which is discrete from and found within the same populations as the more common brown morph. In other species, color polymorphisms are intimately linked with host–parasite interactions, which led us to ask whether blue coloration in lingcod might be associated with parasitism, either as cause or effect. To test how color and parasitism are related in this host species, we performed parasitological dissection of 89 lingcod individuals collected across more than …

Anti-Inflammatory Activity Of Four Triterpenoids Isolated From Poriae Cutis, Lijia Zhang, Mengzhou Yin, Xi Feng, Salam A. Ibrahim, Ying Liu, Wen Huang

Faculty Research, Scholarly, and Creative Activity

In this study, triterpenoid compounds from Poriae Cutis were separated by high-speed countercurrent chromatography (HSCCC) and identified using ultra-high performance liquid chromatography quadrupole time-of-flight tandem mass spectrometry (UHPLC-QTOF-MS/MS) and nuclear magnetic resonance (NMR). The in vitro anti-inflammatory activities of the purified triterpenoids on RAW 264.7 cells were also investigated. Triterpenoids, poricoic acid B, poricoic acid A, dehydrotrametenolic acid, and dehydroeburicoic acid were obtained; their levels of purity were 90%, 92%, 93%, and 96%, respectively. The results indicated that poricoic acid B had higher anti-inflammatory activity than those of poricoic acid A by inhibiting the generation of NO in lipopolysaccharide (LPS)-induced …

The Human Right To Water And Sanitation: Using Natural Language Processing To Uncover Patterns In Academic Publishing, Christopher Michael Faulkner, Joshua Earl Lambert, Bruce M. Wilson, Matthew Steven Faulkner

Faculty Research, Scholarly, and Creative Activity

After years of advocacy and international negotiation, the General Assembly of the United Nations voted to officially recognize a stand-alone human right to water and sanitation on 28 July 2010. Since, academic scholarship has continued to grow in an effort to understand the implications of the codification of this human right. Yet, with this growth, it has become impractical if not impossible for scholars to keep up with the advancement of academic knowledge or to make sense of it in a systematic way. In short, to date, we know very little about the trends in the literature as they have …

Korean Learners’ Acquisition And Use Of Variable First-Person Subject Forms In Spanish, Avizia Y. Long

Faculty Research, Scholarly, and Creative Activity

Within the scope of research that lies at the intersection of sociolinguistics and second language acquisition, there is a growing body of empirical work on learners’ acquisition of variable subject expression in Spanish. This research has been instrumental for demonstrating that second language (L2) learners acquire linguistic and social constraints on subject form use. The present study extends research on variable Spanish subject expression to an understudied learner population: native Korean-speaking learners. Interview data were examined for the range and frequency of first-person subject forms produced by Korean-speaking learners at four instructional levels as well as linguistic and individual (extralinguistic) …

Coupling remote sensing with microbial omics-based approaches provides a promising new frontier for scientists to scale microbial interactions across space and time. These data-rich, interdisciplinary methods allow us to better understand interactions between microbial communities and their environments and, in turn, their impact on ecosystem structure and function. Here, we highlight current and novel examples of applying remote sensing, machine learning, spatial statistics, and omics data approaches to marine, aquatic, and terrestrial systems. We emphasize the importance of integrating biochemical and spatiotemporal environmental data to move toward a predictive framework of microbiome interactions and their ecosystemlevel effects. Finally, we emphasize …

Head-Mounted Accelerometry Accurately Detects Prey Capture In California Sea Lions, Mason R. Cole, Jenifer A. Zeligs, Stefani Skrovan, Birgitte I. Mcdonald

Faculty Research, Scholarly, and Creative Activity

Detecting when and where animals feed is key to understanding their ecophysiology, but our ability to collect these data in marine mammals remains limited. Here, we test a tag-based accelerometry method to detect prey capture in California sea lions. From synchronized underwater video and acceleration data of two trained sea lions, we isolated a combined acceleration and Jerk pattern that reliably indicated prey capture in training datasets. We observed a stereotyped feeding motion in underwater video that included (1) mouth opening while approaching prey; (2) head deceleration to allow initial suction or prey engulfment, and (3) jaw closure. This motion …

Punnett Squares Or Protein Production? The Expert–Novice Divide For Conceptions Of Genes And Gene Expression, Dina L. Newman, Aeowynn Coakley, Aidan Link, Korinne Mills, L. Kate Wright

Faculty Research, Scholarly, and Creative Activity

Concepts of molecular biology and genetics are difficult for many biology undergraduate students to master yet are crucial for deep understanding of how life works. By asking students to draw their ideas, we attempted to uncover the mental models about genes and gene expression held by biology students (n = 23) and experts (n = 18) using semistructured interviews. A large divide was identified between novice and expert conceptions. While experts typically drew box-and-line representations and thought about genes as regions of DNA that were used to encode products, students typically drew whole chromosomes rather than focusing on gene structure …

Neural Upscaling From Residue-Level Protein Structure Networks To Atomistic Structures, Vy T. Duong, Elizabeth M. Diessner, Gianmarc Grazioli, Rachel W. Martin, Carter T. Butts

Faculty Research, Scholarly, and Creative Activity

Coarse-graining is a powerful tool for extending the reach of dynamic models of proteins and other biological macromolecules. Topological coarse-graining, in which biomolecules or sets thereof are represented via graph structures, is a particularly useful way of obtaining highly com-pressed representations of molecular structures, and simulations operating via such representations can achieve substantial computational savings. A drawback of coarse-graining, however, is the loss of atomistic detail—an effect that is especially acute for topological representations such as protein structure networks (PSNs). Here, we introduce an approach based on a combination of machine learning and physically-guided refinement for inferring atomic coordinates from …

Drivers Of Understory Plant Communities In Sierra Nevada Mixed Conifer Forests With Pyrodiversity, Kate Wilkin, Lauren Ponisio, Danny L. Fry, Brandon M. Collins, Tadashi Moody, Scott L. Stephens

Faculty Research, Scholarly, and Creative Activity

Background: Fire suppression in western North America increased and homogenized overstory cover in conifer forests, which likely affected understory plant communities. We sought to characterize understory plant communities and their drivers using plot-based observations from two contemporary reference sites in the Sierra Nevada, USA. These sites had long-established natural fire programs, which have resulted in restored natural fire regimes. In this study, we investigated how pyrodiversity—the diversity of fire size, severity, season, and frequency—and other environment factors influenced species composition and cover of forest understory plant communities. Results: Understory plant communities were influenced by a combination of environmental, plot-scale recent …
