Commentary: The Past, Present, And Future Of The Global Raptor Impact Network, James R. Belthoff, Julie A. Heath

Biology Faculty Publications and Presentations

Most raptor populations are declining and nearly a fifth are threatened with extinction; thus there is a need to increase collaboration to ensure efficient and effective research, management, and conservation. Here, we introduce the Global Raptor Impact Network (GRIN; www.globalraptors.org), a tool to enhance collaboration and conservation impact of the raptor research community. We provide an overview of the history and current state of GRIN, including plans for expansion. Predecessors to GRIN include The African Raptor DataBank, which was launched in 2012 to ascertain the conservation status of raptors across Africa; and the Global Raptor Information Network, which was launched …

The Truth About Brain Cells: Is Adult Neurogenesis Possible?, Ekene Nnagha, Queen-Helen Egbai, Ahtesham Khizar

Pakistan Journal of Neurological Sciences (PJNS)

Brain cells regeneration involves renewal and repair of neurons and other cells in the brain, with restoration of their functions. Although this phenomenon was thought to end in early childhood, research has proven that adult neurogenesis is highly possible with some limitations. Regeneration of axons in the central nervous system is very slow and more complicated than neuronal regeneration, especially regeneration of peripheral nerves. Brain cell regeneration in the adult brain can help in recovery of damaged brain cells and correct cellular and brain tissue dysfunction that are commonly seen in some neurological disorders such as Stroke, Traumatic Brain Injury …

Follow The Smoke: The Pollution Haven Effect On Global Sourcing, Heather Berry, Aseem Kaul, Narae Lee

Research Collection Lee Kong Chian School Of Business

Research abstract: We examine whether and how foreign environmental standards influence global sourcing decisions. Taking a question-driven approach, we find a negative association between the stringency of a country's environmental standards and its share in US imports for 82 manufacturing industries across 77 countries between 2006 and 2016. This pollution haven effect holds not only for sourcing from owned foreign operations (offshore integration), but also for sourcing from unrelated third parties abroad (offshore outsourcing), and is stronger in industries with high toxic emissions and low technological intensity. These results are robust across alternative measures of environmental stringency and to using …

The use of big data and the rise of online platforms have accelerated this process over the past decade. In addition, the adoption of digital solutions in the face of social distancing and lockdown measures introduced due to the coronavirus disease 2019 (COVID-19) pandemic has been integral to the economic recovery process. The shift to a digitalized economy has also reduced barriers to market entry for firms, lowered inequality, and led to a promotion of social and economic inclusion. Advances in digital technology …

Nest Sanitation Behavior Does Not Increase The Likelihood Of Parasitic Egg Rejection In Herring Gulls, James B. Stratton, Donald C. Dearborn

All Faculty Scholarship

Birds’ behavioral response to brood parasitism can be influenced not only by evolution but also by context and individual experience. This could include nest sanitation, in which birds remove debris from their nests. Ultimately, nest sanitation behavior might be an evolutionary precursor to the rejection of parasitic eggs. Proximately, the context or experience of performing nest sanitation behavior might increase the detection or prime the removal of parasitic eggs, but evidence to date is limited. We tested incubation-stage nests of herring gulls Larus argentatus to ask whether nest sanitation increased parasitic egg rejection. In an initial set of 160 single-object …

Economic Impact Of Targeted Government Responses To Covid-19: Evidence From The Large-Scale Cluster In Seoul, Kim, Kanghyock Koh, Jinwook Shin

Research Collection School Of Economics

We estimate the economic impact of South Korea's targeted responses to the first large-scale COVID-19 cluster in Seoul. We find that foot traffic and retail sales decreased only within a 300 meter radius of the cluster and recovered to its pre-outbreak level after four weeks. The reductions appear to be driven by temporary business closures rather than the risk avoidance behavior of the citizens. Our results imply that less intense, but more targeted COVID-19 interventions, such as pin-pointed, temporary closures of businesses, can be a low-cost alternative after lifting strict social distancing measures.

The Effects Of Cost, Level Of Safety, And Severity Of Injury On Manager Decisions To Implement A Safety Solution, Jonathan M. Hochmuth

Dissertations

Workplace injuries continue to be a source of substantial human and financial costs each year. Behavioral safety processes have been effective in reducing workplace injuries by increasing safety-related behaviors. In recent years, the focus in behavioral safety has shifted towards the role of managers in establishing and maintaining safe behaviors and conditions in the workplace. Understanding how managers make decisions to allocate resources is critical to improving safety. The field of behavioral economics has developed methods for studying decision-making. While there have been calls to apply these methods to occupational safety, there are only two empirical studies which have done …

Informing Cognitive Screening In The Young Adult Population, Samantha L. Mcdaniel

Dissertations

The clock drawing test (CDT) is a cognitive screening measure with sound psychometric properties which has been well researched over the past century. The CDT is a popular tool for many healthcare professionals to administer independently or as part of a more thorough cognitive evaluation. Given the drastic technological and social developments over the years since the CDT was developed as well as the persistent research focus on older adult populations, a gap in the CDT literature presented for young adults, who may have difficulty drawing an analog clock. Identifying cognitive impairment can improve health outcomes. The young adult population …

Parametric Characteristics Of The B6omsi-Re, Sarahelizabeth Janemarie Baguhn

Dissertations

Orientation and mobility specialists for young children who are blind or visually impaired have relied on informal assessments or commercially available tools designed for sighted children to track developmental progress. When Bradley-Johnson (1994) literally wrote the book on assessment in blindness, the sharing and refinement of common tools led to professionals working in teams to sift and winnow the checklists, and move the best available tools into wider circulation. This has led to the evolution of the practitioner made tools becoming the published tools, although they have not yet had statistical evidence to support their efficacy. This three-paper dissertation aims …

Advanced Risk Models To Predict Surgical Site Infections Using Machine Learning Approaches And Risk-Adjusted Control Charts, Rabia Emhamed Al Mamlook

Dissertations

Even though most infections are treatable with antibiotics, Surgical Site Infections (SSIs) remain a significant healthcare problem as they increase hospital stays, require additional treatments, reduce a patient’s quality of life, and increase morbidity and mortality. To reduce the risks and to encourage the highest quality healthcare, it is important to measure, predict, and monitor the risk of SSIs. Preoperative prediction of SSIs is essential to facilitate the implementation of preventative strategies for high-risk patients. The overarching goal of this dissertation is to investigate new opportunities of using machine-learning (ML) to improve the accuracy and use of pre-operative prediction models …

A Human-Centric System For Symbolic Reasoning About Code, Megan Fowler

All Dissertations

While testing and tracing on specific input values are useful starting points for students to understand program behavior, ultimately students need to be able to reason rigorously and logically about the correctness of their code on all inputs without having to run the code. Symbolic reasoning is reasoning abstractly about code using arbitrary symbolic input values, as opposed to specific concrete inputs.

The overarching goal of this research is to help students learn symbolic reasoning, beginning with code containing simple assertions as a foundation and proceeding to code involving data abstractions and loop invariants. Toward achieving this goal, this research …

Active Compensation Of Radiation Effects On Optical Fibers For Sensing Applications, Sohel Rana, Austin Fleming, Nirmala Kandadai, Harish Subbaraman

Electrical and Computer Engineering Faculty Publications and Presentations

Neutron and gamma irradiation is known to compact silica, resulting in macroscopic changes in refractive index (RI) and geometric structure. The change in RI and linear compaction in a radiation environment is caused by three well-known mechanisms: (i) radiation-induced attenuation (RIA), (ii) radiation-induced compaction (RIC), and (iii) radiation-induced emission (RIE). These macroscopic changes induce errors in monitoring physical parameters such as temperature, pressure, and strain in optical fiber-based sensors, which limit their application in radiation environments. We present a cascaded Fabry–Perot interferometer (FPI) technique to measure macroscopic properties, such as radiation-induced change in RI and length compaction in real time …

A Multi-Dimensional Child-Langmuir Law For Any Diode Geometry, N. R. Sree Harsha, Marcus Pearlman, Jim Browning, Allen L. Garner

Electrical and Computer Engineering Faculty Publications and Presentations

While prior theoretical studies of multi-dimensional space-charge limited current (SCLC) assumed emission from a small patch on infinite electrodes, none have considered emission from an entire finite electrode. In this paper, we apply variational calculus (VC) and conformal mapping, which have previously been used to derive analytic solutions for SCLC density (SCLCD) for nonplanar one-dimensional geometries, to obtain mathematical relationships for any multi-dimensional macroscopic diode with finite cathode and anode. We first derive a universal mathematical relationship between space-charge limited potential and vacuum potential for any diode and apply this technique to determine SCLCD for an eccentric spherical diode. We …

Respiratory Sound Analysis For The Evidence Of Lung Health, Priyanka Sreerama

Dissertations and Theses

Significant changes have been made on audio-based technologies over years in several different fields along with healthcare industry. Analysis of Lung sounds is a potential source of noninvasive, quantitative information along with additional objective on the status of the pulmonary system. To do that medical professionals listen to sounds heard over the chest wall at different positions with a stethoscope which is known as auscultation and is important in diagnosing respiratory diseases. At times, possibility of inaccurate interpretation of respiratory sounds happens because of clinician’s lack of considerable expertise or sometimes trainees such as interns and residents misidentify respiratory sounds. …

Lorentz Violations And The Casimir Effect, Samuel G. Christensen

Physics

The background and calculation for the corrections to the Casimir Energy stored on parallel conducting plates due to minimal violations of Lorentz invariance are presented as a test of the Standard Model. A direction-dependent photon dispersion relation using operators of dimension 4 and higher is used in the calculation of the spacetime anisotropy correction terms to the Casimir energy. The calculation includes discussion of Riemann zeta function regularization and its equivalence to Euler-Maclaurin sum-integral formulas in a Casimir effect calculation. The two plate geometry result is mapped onto a one plate and sphere geometry to cater to modern precision tests …

Mail Ballot Signature Rejections: Household Members Signing Each Other's Ballots, Craig Wilding

Electronic Theses and Dissertations, 2020-2023

Election administrators anecdotally mention that many ballots get signed by someone else in the household, such as the husband signing the wife's ballot. If household members are signing each other's ballots mistakenly, then there should be a rise in mismatched signatures as the number of people in the household increases. By matching household addresses of registered voters and the addresses that ballots were mailed to from the 2020 Florida general election, the study found that the probability of a signature mismatch did increase as the number of household members increased. While the data showed that black and Hispanic households have …

Using A Data Based Coaching Model To Support Novice Teachers In Inclusive Classrooms, Timara Davis

Electronic Theses and Dissertations, 2020-2023

The inclusion of students with disabilities in the general education classroom has changed over time. Teachers in inclusive classrooms need the skills to teach all students, including students with disabilities. The National Center for Learning Disabilities (NCLD; 2019) reported in a survey of over 1500 general education teachers, only 17% noted they were well prepared to teach students with disabilities. A gap of in content knowledge exists between general and special education teacher preparation (Fonte et al., 2017) and the outcomes of students depends on the knowledge of the teacher (Burroughs et al, 2019). Lack of preparation of general education …

Distributed And Optimal State Estimation For Heterogeneous Dynamic Systems Operating Within A Strongly Connected Network, Matthew Howard

Electronic Theses and Dissertations, 2020-2023

This dissertation is aimed at developing optimal and distributed state estimation algorithms for a team of cooperating nodes with the goal of improving accuracy through local sharing of relevant information. The nodes are assumed to be individually equipped with heterogeneous sensors for measuring a common target which can be dynamic and time-varying. Additionally, the nodes are assumed to be connected through a dynamically changing communication network modeled as a sequence of strongly connected digraphs allowing for local communication and distributed interactions. Using the data sharing afforded by the communication network, a weighted average state estimate consensus can be found across …

Quantifiability: Concurrent Correctness From First Principles, Victor Cook

Electronic Theses and Dissertations, 2020-2023

Architectural imperatives due to the slowing of Moore's Law, the broad acceptance of relaxed semantics and the O(n!) worst case verification complexity of sequential histories motivate a new approach to concurrent correctness. Desiderata for a new correctness condition are that it be independent of sequential histories, compositional over objects, flexible as to timing, modular as to semantics and free of inherent locking or waiting. This dissertation proposes Quantifiability, a novel correctness condition based on intuitive first principles. Quantifiablity is formally defined with its system model. Useful properties of quantifiability such as compositionality, measurablility and observational refinement are demonstrated. Quantifiability models …
