Optimization Of Station-Skip In A Cyclic Express Subway Service, Jingfeng Yang, Hai Wang, Jiangang Jin

Research Collection School Of Computing and Information Systems

With rapid population growth and increasing demand for urban mobility, metropolitan areas such as Singapore, Tokyo, and Shanghai are increasingly dependent on public transport systems. Various strategies are proposed to improve the service quality and capacity of bus and subway systems. Express trains—i.e., trains that skip certain stations—are commonly used because they can travel at higher speeds, potentially reduce travel time, and serve more passengers. In this paper, we study cyclic express subway service (CESS), in which express trains provide routine transport service with cyclic (periodic) station-skip patterns that can be used in daily service. We propose an exact Mixed …

Distpreserv: Maintaining User Distribution For Privacy-Preserving Location-Based Services, Yanbing Ren, Xinghua Li, Yinbin Miao, Robert H. Deng, Jian Weng, Siqi Ma, Jianfeng Ma

Research Collection School Of Computing and Information Systems

Location-Based Services (LBSs) are one of the most frequently used mobile applications in the modern society. Geo-Indistinguishability (Geo-Ind) is a promising privacy protection model for LBSs since it can provide formal security guarantees for location privacy. However, Geo-Ind undermines the statistical location distribution of users on the LBS server because of perturbed locations, thereby disabling the server to provide distribution-based services (e.g., traffic congestion maps). To overcome this issue, we give a privacy definition, called DistPreserv, to enable the LBS server to acquire valid location distributions while providing users with strict location protection. Then we propose a privacy-preserving LBS scheme …

Multi-Head Attention Graph Convolutional Network Model: End-To-End Entity And Relation Joint Extraction Based On Multi-Head Attention Graph Convolutional Network, Zhihua Tao, Chunping Ouyang, Yongbin Liu, Tonglee Chung, Yixin Cao

Research Collection School Of Computing and Information Systems

At present, the entity and relation joint extraction task has attracted more and more scholars' attention in the field of natural language processing (NLP). However, most of their methods rely on NLP tools to construct dependency trees to obtain sentence structure information. The adjacency matrix constructed by the dependency tree can convey syntactic information. Dependency trees obtained through NLP tools are too dependent on the tools and may not be very accurate in contextual semantic description. At the same time, a large amount of irrelevant information will cause redundancy. This paper presents a novel end-to-end entity and relation joint extraction …

Long-Term Mammal Herbivory On Arthropod Assemblages At Kruger National Park, South Africa, Ludzula Mukwevho, Tatenda Dalu, Frank Chidawanyika

All Peer-Reviewed Publications

Protected savannas are essential reserves for biological diversity, including endangered arthropod species, however, extreme grazing by mammals has cascading impacts on the communities and disrupts the functioning of these ecosystems globally. The current study assessed the abundance, species richness and composition of arthropods at the long-term grazing exclosures of Kruger National Park, South Africa. Pitfall traps and active searches were used to sample arthropods at the ungrazed, moderately, and heavily grazed exclosures. We found that Hymenoptera, Coleoptera, Diptera and Araneae were the most abundant orders of arthropods sampled. The abundance of multi-taxon, Diptera and Hymenoptera was significantly different between exclosures. …

Section 25(6) Of The Judicature Act 1873: A ‘Procedural’ Approach, Chee Ho Tham

Research Collection Yong Pung How School Of Law

Section 25(6) was re-enacted as section 136(1), replacing the law French ‘chose in action’ with the more Anglo-Saxon ‘thing in action’, together with other minor differences, but to no substantial effect. Largely unchanged, the construct now found in section 136(1) has been part of English law for 150 years. However, understanding what section 136(1) does, and how it does it, remains muddled. On the one hand, given Lord Macnaghten’s pointed observation in William Brandt’s Sons v Dunlop Rubber that, ‘[section 25(6)] does not forbid or destroy equitable assignments or impair their efficacy in the slightest degree’, Smith & Leslie takes …

Equity In Commerce: Too Much And Too Little?, Man Yip

Research Collection Yong Pung How School Of Law

The interaction and clash between equity and commerce have attracted much attention from judges and academics in recent years. Commercial lawyers may complain about equity introducing uncertainty into commercial endeavours and at times, (mis-)applying the ‘moral standards of the vicarage’ to actors in commercial dealings. However, the objections are not directed at all aspects of equity, but are usually addressed to some ‘disfavoured parts of it’, such as the creation of a new obligation or discretionary remedies. On the other hand, from the perspective of equity lawyers, equity’s interplay with commerce may lead to the contractualisation or commercialisation of equitable …

Proper Purposes And Directors' Duties: Time To Slay The Chimera?, Pearlie M. C. Koh

Research Collection Yong Pung How School Of Law

The statutory statement of directors' duties contained in the Companies Act 2006 imposes a duty on directors to ‘only exercise powers for the purposes for which they are conferred’. The duty has been equiparated with the equitable fraud on a power doctrine. This paper challenges the correctness of this approach, and argues that the unwarranted ‘merging’ of the duty and the doctrine has resulted in a legal chimera standing in the way of a proper understanding of the roles of each of the duty and the doctrine. It is submitted that this erroneous linking of two entirely different concepts is …

A Consortium-Based Solution For The National Institutional Libraries Working On Physical Disabilities Under The Ministry Of Social Justice And Empowerment, Govt. Of India, Sukanta Halder, Dr. Arabinda Maity

Library Philosophy and Practice (e-journal)

The paper aims to find out the present collection, services, and the main problems. The researcher deeply examined the four target libraries and described comparative analysis in different tables with various parameters. All target libraries provide similar types of user needs. Still, collaboration must be found within the target libraries, which is the researcher's main problem. Finally, the researcher prepared and proposed a centralized consortium model that can be very effective for the target libraries and may solve the problems.

The Impact Of Brain Drain On Haiti's Rural Communities: The Case Of A Small Town In Central Haiti And Its Surroundings., Franst Choubert Rémy

Electronic Theses and Dissertations

This qualitative participatory action research study investigated the causes and impacts of brain drain on Haiti’s rural communities, focusing on a small town in Central Haiti and its surrounding communities. Research shows that the brain drain has affected developing countries for many years. The pull factors from developed countries make the push factors in the home country more evident, leaving the latter depleted of educated human resources. It is particularly true in rural communities in Haiti. The researcher aimed to understand the causes through a community-based series of interviews, focus groups, and narratives. Participants expressed their views on the phenomenon …

Preventing Vicarious Trauma And Encouraging Self-Care In Clinical Legal Teaching, Deeya Haldar, Sarah Katz

Faculty Publications

Vicarious trauma, sometimes called “compassion fatigue” or “secondary trauma,” is a term for the effect that working with survivors of trauma may have on counselors, therapists, doctors, attorneys, and others who directly help them. Vicarious traumatisation refers to harmful changes that occur in professionals’ views of themselves, others, and the world as a result of exposure to the graphic or traumatic experiences of their clients. While it is unusual for law students to experience vicarious trauma in a clinical legal education setting, there are good reasons to introduce the concept of vicarious trauma and measures to prevent vicarious trauma through …

Single But Not Solitary: A Call For Nuance In The Study Emerging Adult Singlehood, Jonathon J. Beckmeyer, Tyler Jamison

Faculty Publications

Both research and theory demonstrate that single adults are not a homogeneous group. However, scholars continue to rely on participants to self-identify their relationship status from a list that includes multiple forms of romantic involvement (e.g., casual dating, committed relationship, engaged, married), but only one category of non-involvement: “single.” This approach is especially limiting when studying emerging adults, who are often exploring different forms of sexual and romantic engagement. Consequently, we developed a two-step approach that contextualizes singlehood through the romantic and sexual activities of self-reported single emerging adults. Across three samples of U.S. emerging adults, we found that about …

The Impact Of Parent Training On Student Executive Functioning Skill Use, Nicole Tapia

Graduate Student Dissertations, Theses, Capstones, and Portfolios

This study implemented three parental training sessions in a private pre-kindergarten through twelfth grade school to educate parents of pre-kindergarten through first grade students regarding executive functioning skills in order to determine if teacher's observations of children's classroom behavior and executive functioning skill use and parent's knowledge of executive functioning skills were impacted. Executive functioning skills allow children to plan and achieve goals and have been shown to improve literacy and math proficiency. Executive functioning skills, working memory, inhibition, and cognitive flexibility, used simultaneously, allow children to complete complex mental tasks such as critical thinking (Cortes et al., 2019; Centers …

Peripheral And Central Impact Of Methionine Source And Level On Growth Performance, Circulating Methionine Levels And Metabolism In Broiler Chickens, Craig W. Maynard, Elizabeth Gilbert, Frances Yan, Mark A. Cline, Sami Dridi

Poultry Science Faculty Publications and Presentations

The present study was designed to evaluate the effects of DL-methionine (DL-Met) 2-hydroxy-4-(methylthio) butanoic acid (HMTBa), or S-(5′-Adenosyl)-L-methionine chloride (SAM), using feeding trial and central administration, on live performance, plasma metabolites, and the expression of feeding-related hypothalamic neuropeptides in broilers raised to a market age (35 d). Final average body weight (BW) and feed conversion ratio (FCR) from the feeding trial exceeded the performance measurements published by the primary breeder. At d35, the MTBHa group had better BW and lower feed intake, which resulted in a better FCR than the DL-Met group at 87 TSAA to lysine. At the molecular …

Opposition to the Securities and Exchange Commission’s (“SEC”) new rule on updated climate risk reporting has focused on one category of disclosures as particularly objectionable: Scope 3 emissions.⁷ Otherwise known as “supply chain emissions,” Scope 3 emissions have been voluntarily reported by a growing number of companies since the term was invented as part of the Greenhouse Gas Protocol in 2001.⁸ They include all the emissions both up and downstream of a corporations’ own activities: the emissions of the privately-owned factory that produced the shoes Target sells, as well as the emissions you burn while driving to the …

After Mccleskey, Robert L. Tsai

Faculty Scholarship

In the 1987 decision, McCleskey v. Kemp, the Supreme Court rejected a black death row inmate's argument that significant racial disparities in the administration of Georgia's capital punishment laws violated the Fourteenth Amendment's Equal Protection Clause. In brushing aside the most sophisticated empirical study of a state 's capital practices to date, that ruling seemingly slammed the door on structural inequality claims against the criminal justice system. Most accounts of the case end after noting the ruling's incompatibility with more robust theories of equality and meditating on the deep sense of demoralization felt by social justice advocates. One might …

The New System Of Civil Appeals: What "Constitutional Or Administrative Law" Is; Whether To Appeal To The Appellate Division Or The Court Of Appeal; And Proposals For Further Reform, Benjamin Joshua Ong

Research Collection Yong Pung How School Of Law

An application was made under s 95 of the Legal Profession Act to set aside a penalty imposed by the Council of the Law Society. The Court of Appeal held that an appeal lay to the Appellate Division of the High Court, and not the Court of Appeal, because this was not a “case relating to constitutional or administrative law”. The reasoning is problematic: it relied on an overly narrow conception of “public powers”, conflated judicial review with administrative law more broadly, erroneously considered the merits of the application as relevant to the “which court” question, and overlooked the similarities …

Community Paramedicine In Central Oregon: A Promising Model To Reduce Non-Urgent Emergency Department Utilization Among Medically Complexmedicaid Beneficiaries, Jessica Currier, Neal Wallace, Keshia Bigler, Maggie O’Connor, Paige E. Farris, Jackilen Shannon

OHSU-PSU School of Public Health Faculty Publications and Presentations

Background

Community paramedicine has emerged as a promising model to redirect persons with nonmedically emergent conditions to more appropriate and less expensive community-based health care settings. Outreach through community paramedicine to patients with a history of high hospital emergency department (ED) use and chronic health conditions has been found to reduce ED use. This study examined the effect of community paramedicine implemented in 2 rural counties in reducing nonemergent ED use among a sample of Medicaid beneficiaries with complex medical conditions and a history of high ED utilization.

Methods

A cluster randomized trial approach with a stepped wedge design was …

Biology Faculty Publications and Presentations

Lizards are the most diversified group of living reptiles with 7176 species worldwide (Uetz 2022). They play key roles in ecosystems where they are prey to a wide variety of predators, including snakes, other lizards, mammals, birds, and invertebrates (Pianka and Vitt 2006). The tropical forests of the new world contain a high variety of species of different sizes, shapes, and colors. In Costa Rica in particular, at least 80 species of lizards have been reported (Leenders 2019). They occupy highly diverse habitat types where they participate in food webs that involve many other species of vertebrates and invertebrates.

Femtechnodystopia, Leah R. Fowler, Michael Ulrich

Faculty Scholarship

Reproductive rights, as we have long understood them, are dead. But at the same time history seems to be moving backward, technology moves relentlessly forward. Femtech products, a category of consumer technology addressing an array of “female” health needs, seem poised to fill gaps created by states and stakeholders eager to limit birth control and abortion access and increase pregnancy surveillance and fetal rights. Period and fertility tracking applications could supplement or replace other contraception. Early digital alerts to missed periods can improve the chances of obtaining a legal abortion in states with ever-shrinking windows of availability or prompt behavioral …

Umm Huwaiwitat: A Neolithic Site Near Petra, Jordan, Daniel Plekhov, Cristiano Nicosia, Luiza Osorio G. Silva, Sarah Newman, Felipe Rojas

Anthropology Faculty Publications and Presentations

Studies of the rural landscapes around the Nabataean/Roman city of Petra in Jordan have tended to assume a developmental trajectory based on that of the urban centre. Recent archaeological investigations at the site of Umm Huwaiwitat, however, shed light on the longer-term histories of human occupation and land use in the region north of Petra. Excavation has revealed Late Neolithic deposits formed by the burning of animal dung and the disposal of ash. These deposits underlie walls, today serving as agricultural terraces, which date to at least the Early Bronze Age. Umm Huwaiwitat therefore provides a microcosm of the long-lived …
