A Hybrid Machine Learning Framework For Predicting Students’ Performance In Virtual Learning Environment, Edmund Evangelista

All Works

Virtual Learning Environments (VLE), such as Moodle and Blackboard, store vast data to help identify students' performance and engagement. As a result, researchers have been focusing their efforts on assisting educational institutions in providing machine learning models to predict at-risk students and improve their performance. However, it requires an efficient approach to construct a model that can ultimately provide accurate predictions. Consequently, this study proposes a hybrid machine learning framework to predict students' performance using eight classification algorithms and three ensemble methods (Bagging, Boosting, Voting) to determine the best-performing predictive model. In addition, this study used filter-based and wrapper-based feature …

Questioning The Inclusivity Of Events: The Queer Perspective, Faith Ong, Clifford Lewis, Oscar Vorobjovas-Pinta

Research outputs 2014 to 2021

Event programmes are typically designed with a target audience in mind, and such design can inherently signal inclusion or exclusion of marginalised segments. This is particularly the case for lesbian, gay, bisexual, transgender, intersex and queer (LGBTIQ+) individuals, whose sexual and gender identities position them as an invisible minority on the periphery of society. Given the role of events in building community spirit, it is essential to ensure all members of a community feel able to participate in order to create a sense of belonging, fulfilling Sustainable Development Goals of inclusivity in community. Through the lens of Social Dominance Theory …

Linking Migration To Community Resilience In The Receiving Basin Of A Large-Scale Water Transfer Project, Anna Erwin, Zhao Ma, Ruxandra Popovici, Emma Patricia Salas O’Brien, Laura Zanotti, Chelsea A. Silva, Eliseo Zeballos Zeballos, Jonathan Bauchet, Nelly Ramírez Calderón, Glenn Roberto Arce Larrea

Department of Agricultural Economics Faculty Publications

Large-scale water transfer projects (LWTPs) transfer water to urban and agricultural areas. The Majes-Siguas canal, established in 1983, is an LWTP that created a thriving agricultural area through irrigating the Majes district in the Atacama Desert of Peru. Like other LWTP receiving basins, the project has attracted an influx of migrants who work on the farms. At the same time, the Majes LWTP is the district’s only source of water and has an aging infrastructure which presents significant risks. While many studies critically analyze the consequences of LWTPs in water supply basins, few evaluate the resilience of communities living in …

Commodifying Marginalization, Abbye Atkinson

Duke Law Journal

Pillars of U.S. social provision, public pension funds rely significantly on private investment to meet their chronically underfunded promises to America’s workers. Dependent on investment returns, pension funds are increasingly investing in marginalized debt, namely the array of high-interest-rate, subprime, risky debt—including small-dollar installment loans and other forms of subprime debt—that tends to concentrate in and among historically marginalized communities, often to catastrophic effect. Marginalized debt is a valuable investment because its characteristically high interest rates and myriad fees engender higher returns. In turn, higher returns ostensibly mean greater retirement security for ordinary workers who are themselves economically vulnerable in …

The Economic Dimensions Of Family Separation, Stephen Lee

Duke Law Journal

Migrants in the United States experience varying degrees of harm related to family separation. This article focuses on the economic dimensions of these harms by focusing on transnational remittances, a topic that has generated significant scholarly attention. Within this story, remitters are pitched as heroes and remittances are held up as a critical, market-based solution for solving global poverty. Of course, this picture is incomplete. This account ignores remittance-sending countries and provides only a narrow account of law. This Article focuses on anti-money laundering policies, an important set of U.S. laws that regulate the remittance economy. Examining remittances from this …

Give And Take: State Courts Should Be Able To Certify Questions Of Federal Law To Federal Courts, John Macy

Duke Law Journal

For some time, federal courts faced with unresolved questions of state law have been able to certify those questions to state courts for resolution. In the past half-century, certification practice has exploded. Nearly every state allows at least one federal court to certify questions to its state courts, and some federal courts exercise the option frequently. However, there is no analogous tool for state courts to certify questions of federal law to federal courts. This Note argues that the creation of such a tool would benefit both courts and litigants. Of course, the considerations motivating certification to state courts, such …

Mass Comments’ Opportunity Costs, Michael Herz

Online Publications

Agencies, courts, and academics agree that notice-and-comment rulemaking is not a referendum. But that conceptualization presents a challenge when an agency is confronted with mass comments. If agencies are not counting but reading comments, and if mass comments are duplicative and often devoid of content beyond a strong expression of values or preference, then what do they add?

‘Stuck’ In The Waiting Room: African And Haitian Migrants Between Liminality And Mobility In A Mexican Border Town, Julia Hause

Theses and Dissertations

This thesis explores the border town of Tijuana, Mexico as a site of fragmentation and rupture along the migration journeys of African and Haitian migrants transiting the South American-Central American corridor towards North American destinations. Extra-continental migration of migrants from Africa, Asia, and the Caribbean to Latin America has been an emerging migration trend as global migration governance becomes increasingly restrictive and externalized. U.S. immigration and asylum policies implemented at the southern border have made migrating and making claims to international protection difficult for those migrants who arrive at the border. These policies, coupled with the indefinite U.S. land border …

Regulating Homeowners' Disaster Insurance Through Federal Intervention: Lessons From The Affordable Care Act, Shannon O'Hara

Duke Law Journal

One of the most impactful effects of climate change in recent years has been the increasing frequency and severity of natural disasters, even in geographic areas not previously known as disaster-prone. These disasters have caused untold property damage. Typically, the cost of rebuilding a home is assumed at least in part by private insurance companies, but many homeowners are significantly underinsured for disaster-related losses. Additionally, in areas where natural disasters are becoming increasingly frequent, private insurers have determined that it is no longer profitable to continually issue massive payouts without charging astronomical premiums, leaving many homeowners without access to financial …

Recurrent High-Impact Mutations At Cognate Structural Positions In Class A G Protein-Coupled Receptors Expressed In Tumors, Eunna Huh, Jonathan Gallion, Melina A Agosto, Sara J Wright, Theodore G Wensel, Olivier Lichtarge

Faculty, Staff and Students Publications

G protein-coupled receptors (GPCRs) are the largest family of human proteins. They have a common structure and, signaling through a much smaller set of G proteins, arrestins, and effectors, activate downstream pathways that often modulate hallmark mechanisms of cancer. Because there are many more GPCRs than effectors, mutations in different receptors could perturb signaling similarly so as to favor a tumor. We hypothesized that somatic mutations in tumor samples may not be enriched within a single gene but rather that cognate mutations with similar effects on GPCR function are distributed across many receptors. To test this possibility, we systematically aggregated …

Sap Beetles, Nick Volesky, Zachery R. Schrumm, Kalen Taylor

All Current Publications

Sap beetles are typically considered a secondary pest of corn and overripe fruits and vegetables. They are broadly identified by their small and ovular bodies and club-shaped antennae. Adult sap beetles often feed on corn silk, pollen, and tassels. Larvae feed on kernels inside the husk. This fact sheet reviews how to identify sap beetles and their hosts and damage. It also provides ideas on how to monitor for sap beetles and outlines the options for managing them.

IGC Proceedings (1977-2023)

The objective of this study was to assess the effect of Italian ryegrass (Lolium multiflorum Lam.) sward height on lamb performance. The experiment was carried out at the Research Station of UFRGS, Eldorado do Sul, Brazil. Yearling no-castrated male lambs were assessed in terms of individual animal performance and gain per hectare. The experiment was carried out in a randomised block design with three replications of four treatments: 5, 10, 15 and 20 cm of sward surface height (SSH), which were maintained using continuous variable stocking, and monitored by a sward stick. Samples of 0.25 m² were cut …

Animal Performance In Pastures Of Panicum Maximum Cv. Ipr 86 Fertilized With Nitrogen, S. M. B. Lugão, L. R. De A. Rodrigues, E. B. Malheiros, J. J. Dos S. Abrahão, A. De Morais

IGC Proceedings (1977-2023)

The experiment was carried out at the Experimental Station of the IAPAR in Paranavaí– PR, Brazil, from October 1998 to May 1999 to evaluate the response of crossbred steers grazing pastures of Panicum maximum cv. IPR 86 fertilized with four doses of N (0; 150; 300 and 450 kg.ha^-1.year). The grass was grazed according to a rotational grazing system with grazing cycles (GCs) of 40 days (grazing period of 5 days and rest period of 35 days). It was used a randomized complete block design, with split-plots, and two replications per treatment, being the N-doses studied in the …

Dairy Cow Performance On Pasture-Based Feeding Systems And In Confinement, Renato S. Fontaneli, Lynn E. Sollenberger, C. R. Staples

IGC Proceedings (1977-2023)

Interest in grazing systems is growing among farmers in the USA as a means of reducing feed costs for lactating dairy cows. An experiment was conducted near Gainesville, FL to compare milk production and composition and milk income minus feed costs from two pasture-based systems with those of a conventional confinement housing system over a 276-d period. System 1 was based on a mixture of rye (Secale cereale L.), annual ryegrass (Lolium multiflorum Lam.), crimson clover (Trifolium incarnatum L.), and red clover (Trifolium pratense L.) during the winter-spring seasons and pearl millet (Pennisetum glaucum [L.] …

Differences In At-Risk Children's Preschool Assessment By Educators' Levels Of Education, Folashade Z. Olayinka-Bello, Donna Brackin

Journal of Educational Research and Practice

We determined that significant differences existed between assessment scores of at-risk children taught by assistant teachers with different levels of education using standardized assessments (Teaching Strategies GOLD [TSG] and Phonological Awareness Literacy Screening [PALS]). A 1-way MANOVA indicated that assistant teachers’ level of education was statistically significant at p = .012. Archived pretest and posttest data were collected from TSG and PALS assessment scores of 142 at-risk Prekindergarten 4 children taught by 18 different Prekindergarten 4 lead and assistant teachers at a local Head Start site. We found that irrespective of teachers’ levels of education, the role of assistant teachers …
