Articles

Suboptimal cataract surgery outcomes remain a challenge in most developing countries. In Ghana, about 2 million people have been reported to be blind due to cataract with about 20% new cases being recorded yearly. The aim of this study was to evaluate postoperative correction of refractive errors after cataract surgery in a selected eye hospital in Ashanti Region, Ghana. This was a retrospective study where medical records of patients (aged 40–100) who reported to an eye hospital in Ghana from 2013–2018 were reviewed. Included in the study were patients aged ≥40 years and patients with complete records. Data on patient …

Big Data: Potential As An Ocular Epidemiology And Public Health Tool, Michael Moore Jan 2021

Big Data: Potential As An Ocular Epidemiology And Public Health Tool, Michael Moore

Doctoral

Refractive error is a significant cause of vision impairment both through the limited access to correction in some areas and the associated ocular diseases for which refractive errors are risk factors. Having timely, regular access to population level estimates of refractive error and vision impairment is necessary to adequately plan public health resources and resource appropriate interventions. A lack of access to current and regularly updated refractive error and vision impairment prevalence data has been identified as a significant limitation in predicting future population trends with many countries lacking any prevalence data or available data being outdated. This project addresses …

The Design And Evaluation Of An Educational Software Development Process For First Year Computing Undergraduates, Catherine Higgins Jan 2021

The Design And Evaluation Of An Educational Software Development Process For First Year Computing Undergraduates, Catherine Higgins

Doctoral

First year, undergraduate computing students experience a series of well-known challenges when learning how to design and develop software solutions. These challenges, which include a failure to engage effectively with planning solutions prior to implementation ultimately impact upon the students’ competency and their retention beyond the first year of their studies. In the software industry, software development processes systematically guide the development of software solutions through iterations of analysis, design, implementation and testing. Industry-standard processes are, however, unsuitable for novice programmers as they require prior programming knowledge. This study investigates how a researcher-designed educational software development process could be created …

Just-In-Time Pastureland Trait Estimation For Silage Optimization, Under Limited Data Constraints, Patricia O'Byrne Jan 2021

Just-In-Time Pastureland Trait Estimation For Silage Optimization, Under Limited Data Constraints, Patricia O'Byrne

Doctoral

To ensure that pasture-based farming meets production and environmental targets for a growing population under increasing resource constraints, producers need to know pastureland traits. Current proximal pastureland trait prediction methods largely rely on vegetation indices to determine biomass and moisture content. The development of new techniques relies on the challenging task of collecting labelled pastureland data, leading to small datasets. Classical computer vision has already been applied to weed identification and recognition of fruit blemishes using morphological features, but machine learning algorithms can parameterise models without the provision of explicit features, and deep learning can extract even more abstract knowledge …

Finn, Elaine Kay, William M. Gallagher, William G. Watson, Aoife Gowen, Patrick Jackman

Articles

The diagnosis of prostate cancer is challenging due to the heterogeneity of its presentations, leading to the over diagnosis and treatment of non-clinically important disease. Accurate diagnosis can directly benefit a patient’s quality of life and prognosis. Towards addressing this issue, we present a learning model for the automatic identification of prostate cancer. While many prostate cancer studies have adopted Raman spectroscopy approaches, none have utilised the combination of Raman Chemical Imaging (RCI) and other imaging modalities. This study uses multimodal images formed from stained Digital Histopathology (DP) and unstained RCI. The approach was developed and tested on a set …

Let Knowledge Make Recommendations For You, Zhiixue Jiang, Chengying Chi, Yun Yun Zhan Jan 2021

Let Knowledge Make Recommendations For You, Zhiixue Jiang, Chengying Chi, Yun Yun Zhan

Articles

The knowledge graph can make more accurate personalized recommendations for the recommendation system, but it is also interpretative and has traces to follow. The purpose of the recommendation system is to recommend a series of unobserved items for users. At present, recommendation systems based on knowledge graphs are mainly implemented in two ways: Embedding-based and path based. Embedding methods usually directly use information from the knowledge graph to enrich the representation of an item or user. Still, it failed to introduce multi-hop relations, and it is challenging to use semantic network information. A path-based recommendation algorithm utilizes the knowledge graph …

Prosecuting Foreign States, Chimene Keitner Jan 2021

Prosecuting Foreign States, Chimene Keitner

Faculty Scholarship

In recent years, the Department of Justice has shown increased interest in prosecuting entities associated with foreign states for activities including cybercrime, economic espionage, and sanctions violations. It has also sought third-party evidence from foreign state-owned entities in connection with high-profile criminal investigations, including the Mueller investigation. These actions raise fundamental questions about the immunities of foreign states and state-owned entities from U.S. criminal proceedings. This Article provides the first comprehensive analysis of—and answer to—these basic questions. In doing so, it upends the widespread but misleading perception that the Foreign Sovereign Immunities Act of 1976 (FSIA) provides the sole basis …

We Are The River, David Takacs Jan 2021

We Are The River, David Takacs

Faculty Scholarship

The New Zealand Parliament has recently granted the Whanganui River and the Te Urewera mountain ecosystem rights as legal persons, with a Māori governing board to speak for the nonhuman entities, based upon traditional cultural precepts. Far from an isolated precedent, in what the U.N. Secretary General calls “the fastest growing legal movement of the twenty-first century,” legislatures, courts, or voters in Australia, Colombia, Ecuador, Bangladesh, India, Uganda, and the U.S. have also declared that rivers and other living systems have legal rights. This Article chronicles the movement to grant nonhuman entities legal rights. I analyze the statutes and judicial …

Virtual Reality: Prospective Catalyst For Restorative Justice, Kate Bloch Jan 2021

Virtual Reality: Prospective Catalyst For Restorative Justice, Kate Bloch

Faculty Scholarship

A 2018 U.S. Department of Justice report assessing data from thirty states found that eighty-three percent of those individuals released from state prisons in 2005 were rearrested within nine years.** When a revolving door ushers five of six individuals back into custody and decimates communities, more effective approaches to criminal justice demand attention. In countries around the world, restorative justice has been emerging as a promising candidate. It generally involves an interactive process in which stakeholders identify and grapple with harms caused by the crime. But many environments lack the resources to invoke its benefits. While restorative justice takes various …

Physicians Treating Alzheimer’S Disease Patients Should Be Aware That Televised Direct-To-Consumer Advertising Links More Strongly To Drug Utilization In Older Patients, Robin C. Feldman Jan 2021

Physicians Treating Alzheimer’S Disease Patients Should Be Aware That Televised Direct-To-Consumer Advertising Links More Strongly To Drug Utilization In Older Patients, Robin C. Feldman

Faculty Scholarship

Background: US direct-to-consumer advertising spending for medicine has soared in recent decades. Advertising has been shown to impact drug utilization. Most Alzheimer’s disease patients are above age 65 and may take a range of prescription medications for various disease states. Objective: To investigate how direct-to-consumer advertising is associated with the drug utilization of patients ≥ 65 years old. Methods: Using advertising expenditure data and Medicare Part D drug purchase claims, we performed regression analyses for each of the highest-spending drugs and age group, with cumulative monthly spending as the predictor variable and drug utilization as the response variable. For each …

Texas V. Pennsylvania And The Political-Question Doctrine, Scott Dodson Jan 2021

Texas V. Pennsylvania And The Political-Question Doctrine, Scott Dodson

Faculty Scholarship

In the wake of the 2020 presidential election, Texas sued four other states in an original action in the U.S. Supreme Court arguing that those states violated, among other constitutional provisions, the Electors Clause. One issue the Supreme Court did not reach in the case—and has never reached before—was the impact of the political-question doctrine on claims under the Electors Clause. This short essay takes up that issue. Analyzing the applicability of the political-question doctrine to the Electors Clause, I conclude that the political-question doctrine operates as only a narrow constraint on Electors Clause claims. Applying those principles, I conclude …

The Chinese Advantage In Emergency Law, Ugo Mattei, Guanghua Liu, Emanuele Ariano Jan 2021

The Chinese Advantage In Emergency Law, Ugo Mattei, Guanghua Liu, Emanuele Ariano

Faculty Scholarship

This Article has a twofold purpose. On the one hand, it offers comparative materials for an informed discussion of COVID-determined emergency law in China and Italy by assessing its normative implications and political genealogy. On the other hand, it explores the essential contiguity between the ‘state of exception’ triggered by the pandemic and the possible geopolitical shifts in global legal hegemony in the actual phase of surveillance capitalism which is witnessing a decline of law as a form of social organization and its replacement by the predictive models elaborated by technology. In this respect, the traditional Western iconography has long …

Bad Role Models? American Influence On Israeli Criminal Justice Policy, Hadar Aviram Jan 2021

Bad Role Models? American Influence On Israeli Criminal Justice Policy, Hadar Aviram

Faculty Scholarship

In this Article I rely on the public policy concept of "policy transfer" to examine the impact of U.S. legislation, litigation, and politics on the Israeli criminal justice landscape. The Article identifies four eras: 1. The Great Light from the West - the ascent of U.S. criminal justice as British influence fades; 2. The Decade of Rights - a misperception of America as a paragon of criminal justice rights and protections that results in influences on Israeli jurisprudence; 3. The Law-and-Order Enchantment Period - a time at which Israeli scholars and policymakers import punitive trends from the U.S., particularly in …

Differential Etiology: Inferring Specific Causation In The Law From Group Data In Science, Joseph Sanders, David L. Faigman, Peter B. Imrey, Philip Dawid Jan 2021

Differential Etiology: Inferring Specific Causation In The Law From Group Data In Science, Joseph Sanders, David L. Faigman, Peter B. Imrey, Philip Dawid

Faculty Scholarship

In every toxic-tort case, the plaintiff must prove that the defendant exposed the plaintiff to something that caused an injury. The causal proof is in two parts: proof of general causation and proof of specific causation. General causation addresses the question of whether the exposure can cause injury in anyone. In the area of toxic torts, the evidence available to answer this question comes in the form of groupbasedstudies in the fields of toxicology, epidemiology, and genetics—studies that search for the effects of causes. Proof of general causation, however, is not enough. Because court cases focus on the individual, the …

A Roadmap For Foreign Official Immunity Cases In Us Courts, William S. Dodge, Chimene I. Keitner Jan 2021

A Roadmap For Foreign Official Immunity Cases In Us Courts, William S. Dodge, Chimene I. Keitner

Faculty Scholarship

This Article provides a roadmap for cases involving foreign official immunity in U.S. courts. In 2010, the U.S. Supreme Court held in Samantar v. Yousuf that the Foreign Sovereign Immunities Act (FSIA) does not govern the immunity of foreign officials. Since Samantar, dozens of decisions have addressed questions of foreign official immunity. Yet, U.S. courts often seem lost. They frequently fail to engage with the customary international law rules of foreign official immunity, instead reaching back to an outdated provision of the 1965 Restatement (Second) of Foreign Relations Law. Courts are divided on how much deference to give the executive …

School Police Reform: A Public Health Imperative, Thalia Gonzalez, Emma Kaeser Jan 2021

School Police Reform: A Public Health Imperative, Thalia Gonzalez, Emma Kaeser

Faculty Scholarship

Out of the twin pandemics currently gripping the United States—deaths of unarmed Black victims at the hands of police and racialized health inequities resulting from COVID- 19—an antiracist health equity agenda has emerged that identifies racism as a public health crisis. Likewise, calls for reform of school policing by those advocating for civil rights, racial justice, and Black Lives Matter have simultaneously intensified. Yet each remains siloed, despite the natural connection and implicit overlap between these separate movements and debates. Indeed, there are documented negative health effects of school policing for Black, Indigenous, people of color (BIPOC) youth. But these …

Restorative Justice, School Reopenings And Educational Equity: A Contemporary Mapping And Analysis Of State Law, Thalia Gonzalez, Rebecca Epstein, Claire Krelitz, Rhea Shinde Jan 2021

Restorative Justice, School Reopenings And Educational Equity: A Contemporary Mapping And Analysis Of State Law, Thalia Gonzalez, Rebecca Epstein, Claire Krelitz, Rhea Shinde

Faculty Scholarship

The opportunity to use restorative justice practices to address structural inequalities and reimagine school structures has become increasingly important in the wake of twin social and public health pandemics. As research-based restorative practices continue to grow across the country with the aim of fostering supportive, safe, and anti-racist learning environments, calls to codify school-based restorative justice are spreading. Despite the prevalence of on-the-ground practices since the 1990s and a growing evidence base for school-based restorative practices, there is little understanding of the effect of the legalization of restorative justice on individual- or school-level outcomes. This study is the first analysis …

Retheorizing Progressive Taxation, Manoj Viswanathan Jan 2021

Retheorizing Progressive Taxation, Manoj Viswanathan

Faculty Scholarship

Progressively taxing consumption has much normative appeal, but pre­ vious legal scholarship has incorrectly assumed that directly accounting for the expenditures of individual taxpayers is administratively infeasible. Changes in consumer spending and advances in technology require revisiting this assumption. This article proposes a novel framework through which an individual accounting progressive consumption tax (IAPCT) can be imple­ mented and establishes the IAPCT's superiority to previously proposed forms of progressive consumption taxation. IAPCT advantages include a significant reduction in tax filing costs, improved enforcement, and the immediate de­ ployment of place-based tax policy.

Noninvasive Genetic Sampling With A Bayesian Spatial Capture-Recapture Analysis To Estimate Abundance Of Roosevelt Elk (Cervus Canadensis Roosevelti), Makenzie Henk Jan 2021

Noninvasive Genetic Sampling With A Bayesian Spatial Capture-Recapture Analysis To Estimate Abundance Of Roosevelt Elk (Cervus Canadensis Roosevelti), Makenzie Henk

Cal Poly Humboldt theses and projects

Determining abundance of Roosevelt elk (Cervus canadensis roosevelti) in central Humboldt County, California has presented a unique challenge to wildlife managers due to the dense forest habitat and the animals’ elusive behavior. As the elk population has increased, so has human-wildlife conflict, and wildlife agencies need efficient and repeatable methods for determining abundance to inform management decisions. Traditional monitoring methods such as helicopter surveys are ineffective due to low sighting probability and strong behavioral responses to the aircraft. They also often lead to biased sex ratios when the distribution of males and females varies across the landscape. Non-invasive …

Comparison Of Low-Cost Commercial Unpiloted Digital Aerial Photogrammetry To Airborne Laser Scanning Across Multiple Forest Types In California, James Edward Lamping Jan 2021

Comparison Of Low-Cost Commercial Unpiloted Digital Aerial Photogrammetry To Airborne Laser Scanning Across Multiple Forest Types In California, James Edward Lamping

Cal Poly Humboldt theses and projects

Science-based forest management requires quantitative information about forest attributes traditionally collected via sampled field plots in a forest inventory program. Remote sensing tools, such as active three-dimensional (3D) Light Detection and Ranging (lidar), are increasingly utilized to supplement and even replace field-based forest inventories. However, lidar remains cost prohibitive for smaller areas and repeat measurement, often limiting its use to single acquisitions of large contiguous areas. Recent advancements in unpiloted aerial systems (UAS), digital aerial photogrammetry (DAP) and high precision global positioning systems (HPGPS) have the potential to provide low-cost time and place flexible 3D data to support forest inventory …

Laboratory To Landscape: Mycorestoration, Riley Sanae Allen Jan 2021

Laboratory To Landscape: Mycorestoration, Riley Sanae Allen

Cal Poly Humboldt theses and projects

Mycorestoration is the use of saprophytic fungi to remediate pollutants from land and water. To address contaminant presence in non-point source pollution primarily from agricultural runoff, we worked towards identifying the community-scale implementation process of mycofiltration, a type of mycorestoration that filters contaminants from water, in Arcata, California. This place-based study used Participatory Action Research (PAR) to collaboratively conduct Transdisciplinary Research (TR) to collect baseline qualitative and quantitative data that did not exist for Arcata’s context. These data have been compiled into a written implementation plan which is intended to exist as a living document that is referenced and transformed …

Wingate Muscular Power Test Reference Values For Active Healthy Adults Ages 19-29: Normative Data And Differences Between Sex, Levi Basist Jan 2021

Wingate Muscular Power Test Reference Values For Active Healthy Adults Ages 19-29: Normative Data And Differences Between Sex, Levi Basist

Cal Poly Humboldt theses and projects

The Wingate Muscular Power Test (WMPT) has existed for several decades and to this day is considered the gold standard for evaluating an individual’s muscular power. However, the utility of this test is predicated on having accurate and relevant normative data with which to compare individual results. At present, the existing literature on this subject is either several decades old and/or inclusive of only specific subject groups (i.e. men only or sport-specific athletes). This study presents WMPT normative values for active healthy adults ages 19-29, separated by sex. The sample consisted of 330 active healthy volunteers (186 men and 144 …

Can A Remote Sensing Approach With Hyperspectral Data Provide Early Detection And Mapping Of Spatial Patterns Of Black Bear Bark Stripping In Coast Redwoods?, Shayne R. Magstadt

Cal Poly Humboldt theses and projects

The prevalence of black bear (Ursus americanus) bark stripping in commercial redwood (Sequoia sempervirens) timer stands has been increasing in recent years. This stripping is a threat to commercial timber production because of the deleterious effects on redwood tree fitness. This study sought to unveil a remote sensing method to detect these damaged trees early and map their spatial patterns. By developing a timely monitoring method, forest timber companies can manipulate their timber harvesting routines to adapt to the consequences of the problem. We explored the utility of high spatial resolution UAV-collected hyperspectral imagery as a …
