Strategic Use Of Once-A-Day Milking For Pasture-Based Dairy Cows In Ireland, John Paul Murphy

Theses

The current perception of dairy farming in Ireland is one of long hours, physically demanding work and poor remuneration, especially when compared to that of a modern, high-tech industry with career opportunities and advancement possibilities at many levels (Teagasc, 2018). One of the biggest factors in attracting and retaining people to work on Irish dairy farms is that they must be desirable places to work (Teagasc, 2018). Milking is the most labour demanding task on Irish dairy farms (Deming et al., 2018) and one, which necessitates farmers being present on the farm twice daily if milking twice-a-day (TAD). Altering milking …

The Impact Of Data Quality On Beef Genetics, Shauna Walsh

Characterisation Of Asymptomatic Bacteriuria (Abu) Isolates And Their Antimicrobial Activity Against Uropathogenic Escherichia Coli (Upec), Ciara Kenneally

Theses

Uropathogenic Escherichia coli (UPEC) is the most common aetiological agent of community and hospital-acquired urinary tract infections (UTIs). UTIs caused by E. coli result in considerable morbidity, mortality, and economic loss worldwide due to increasing resistance to antibiotics. Substantial efforts are being made to develop novel alternatives to conventional antibiotic therapies. One approach is the principle of bacterial interference; using low-virulence, or commensal, bacteria to prevent colonisation of pathogens by competing for nutrients, or producing antimicrobial compounds such as bacteriocins. E. coli isolates inducing asymptomatic bacteriuria (ABU) have been proposed as a therapeutic alternative for UPEC infection. ABU is a …

The Exploitation Of Genomic Information For Dairy And Beef Cattle Breeding, Cliona Ryan

Theses

Genotype information is now available for over 4 million Irish dairy and beef cattle, and is primarily used for parent verification and genomic evaluations. Additional benefits that can be generated from genomic data should be explored to maximise the respective return-on- investment. This thesis investigated novel approaches that leverage genome-wide genomic information in cattle, focusing on using the genotype data to accurately determine breed composition, to quantify the association between major genes and performance traits, and to identify karyotype abnormalities. Furthermore, the value of genotyping for the purpose of identifying genetically superior animals depends largely on the accuracy of the …

Examining Stigma In Rural Mental Health Care Settings: A Mixed Methods Approach, Lainie Krumenacker

Murray State Theses and Dissertations

More than half of Americans will be diagnosed with a mental illness in their lifetime (CDC, 2021), yet stigma towards mental health affects both patients and providers. Although programs exist to address stigma, improve cultural competency among providers, and educate families on the importance of support, facilities are often limited on programs they provide due to allocation of resources and funds. Without a shift in treatment and programing, stigma will continue to impact patient care and outcome.

This study explored stigma among mental health providers in rural communities, while exploring potential differences in treatment among patients due to race. Mental …

Social Bonds And Perception: Investigating Individual And Contextual Differences In Empathic Processing, Tyler J. Robinson

Murray State Theses and Dissertations

Empathy is defined as the process by which individuals consciously experience affective states that are similar to a target’s affective state (de Vignemont & Singer, 2006). Singer and Lamm (2009) assert that empathy is a malleable construct and can be influenced by various factors. Relatedly, more research is needed to understand whether positive empathy patterns similarly to negative empathy (Morelli et al., 2015). The current study sought to investigate how differences in perspective-taking and degree-of-closeness influence an individuals’ emotional response to an ostensibly positive vignette. Results reliably suggest a main effect of degree-of-closeness on individuals’ positive affect, whereas relatively little …

Tilted Fiber Bragg Grating Sensors Based On Time-Domain Measurements With Microwave Photonics, Shiyu Li, Ruimin Jie, Osamah Alsalman, Jie Huang, Chen Zhu

Electrical and Computer Engineering Faculty Research & Creative Works

Tilted fiber Bragg gratings (TFBGs) have garnered substantial research attention and have found widespread applications for sensing a diverse array of physical, chemical, and biological parameters based on optical spectrum measurements. The interrogation of a TFBG sensor typically requires a high-resolution bulky optical spectrum analyzer (OSA) due to the extremely narrow dips caused by the resonance of cladding modes. However, high-resolution OSAs can be costly and have limitations on measuring speed, limiting their practicality. In this paper, a new approach to interrogating TFBG sensors is proposed and experimentally demonstrated based on a microwave photonics technique. Instead of measuring the optical …

Evaluation Of Transfer Learning Models On Traumatic Brain Injury Severity Classification, Ngoc Do, Daniel B. Hier, Tayo Obafemi-Ajayi

Electrical and Computer Engineering Faculty Research & Creative Works

After traumatic brain injury (TBI), clinicians use the Glasgow Coma Scale (GCS) to classify patients by severity and radiologists use the Rotterdam score and the Marshall score to classify CT scans by severity. This work investigates a viable efficient low-cost transfer learning model to use MRI images to predict GCS, Rotterdam, and Marshall severity class after TBI. The enhanced transfer learning model architecture integrates multiple fine-tuning steps in which a few layers of the pre-trained model is unfrozen in each iteration so that the neural network is able to learn layer by layer further aspects of the image for better …

In-Plane And Out-Of-Plane 2-D Microdisplacement Sensor Based On A Single Microwave Resonator With Machine Learning, Shiyu Li, Osamah Alsalman, Jie Huang, Chen Zhu

Electrical and Computer Engineering Faculty Research & Creative Works

Microwave displacement sensors have garnered significant research interest in recent years and have found successful applications in industrial automation and aerospace engineering. However, most microwave sensors are limited to measuring in-plane displacement, with the assumption that out-of-plane displacement remains constant during operation. In this work, we propose and experimentally demonstrate a novel concept for 2-D micro displacement sensing that simultaneously measures both in-plane and out-of-plane displacement. We developed a proof-of-concept sensor system based on a custom-made coaxial cable resonator (CCR) serving as the stator and a rubber-metal heterogeneous plate as the movable part. The in-plane and out-of-plane micromovements of the …

Wrongful Convictions, Wrongful Prosecutions And Wrongful Detentions In India, Kent Roach

National Law School of India Review

The first part of this article examines wrongful convictions in India. In part because of the absence of a jury, appellate courts, including the apex court, are more willing to evaluate whether the evidence for a conviction is sufficient than appellate courts in other common law systems. From 2016 to 2022, the High Courts and the Supreme Court have acquitted over two hundred accused in death penalty cases alone. The willingness of appellate courts to acquit is a strength of the Indian system that should be maintained. At the same time, remedied wrongful convictions in India likely represent only the …

Electrical and Computer Engineering Faculty Research & Creative Works

Natural organic memristors are promising synapse candidates for neuromorphic systems due to their significant benefits, such as environmental sustainability, low production and disposal cost, non-volatile storage capability, and bio/CMOS-compatibility. In this paper, experimental evaluations of a neuromorphic system based on honey-memristors are reported. First, honey-memristors are manufactured and tested based on our in-house technology, and then the non-linear characteristics inherent to honey-memristors, which causes inaccurate weight updates and reduces the inference accuracy, are explored. A non-linear mapping (NMP) method is applied to mitigate the effects of non-linearity in honey-memristor, under different scenarios including multiple cycle-to-cycle variations and Analog-to-Digital Converter (ADC) …

Over the past decade, boldine, a naturally occurring alkaloid found in several plant species including the Chilean Boldo tree, has garnered attention for its efficacy in rodent models of human disease. Some of the properties that have been attributed to boldine include antioxidant activities, neuroprotective and analgesic actions, hepatoprotective effects, anti-inflammatory actions, cardioprotective effects and anticancer potential. Compelling data now indicates that boldine blocks connexin (Cx) hemichannels (HCs) and that many if not all of its effects in rodent models of injury and disease are due to CxHC blockade. Here we provide an overview of boldine's pharmacological properties, including its …

Gender In The Making Of The Constitution: Proposals For A Feminist Inquiry Into Indian Constitutional History, Achyut Chetan

National Law School Journal

A feminist inquiry into the framing of the Indian Constitution must retrieve and see the interventions of the women members of the Constituent Assembly for what they historically represent, namely, a feminist authorial voice that was developed over a period of time by the pre-Independence women’s movement in India. For a proper understanding of this voice, we must understand the gendered character of the Constituent Assembly, its architecture, its procedures, the dynamics of the gendered relations among its members, and above all, the performative aspects of the debates. This inquiry must also investigate the language employed by the members and …

From Criminalizing China To Criminalizing The Chinese, Leo Yu

Faculty Journal Articles and Book Chapters

Many scholars have studied the racialization of Asian Americans and found that perpetual foreignness stands at the core of their ascriptive identity. This identity was formed in the 19th century and is also closely related to the dominant society’s racial understanding of ‘the Chinese’—which refers, for the purposes of this article, to people of actual or perceived Chinese descent in the United States. This article investigates this racialization process, with a contemporary lens: What does perpetual foreignness mean to the Chinese in the 21st century?

This Article argues that, for the Chinese, their foreignness in today’s United States means more …

Generative AI is booming. This technology offers amazing opportunities for growth in various business sectors and creates the opportunity for swift progress on medical innovations, climate change, world hunger, and innumerable other areas. AI also poses a number of challenges, though, such as replacing human workers and exacerbating pernicious biases. Another major concern about generative AI is singularity-the idea that this technology could surpass human intelligence and subjugate us or render us extinct. Although some commentators discount this possibility, the fact that AI experts such as Geoffrey Hinton, Sam Altman, and Elon Musk share the singularity concern should at least …

The Emerging Crime Of Persecution Based On Sexual Orientation, Anthony J. Colangelo

Faculty Journal Articles and Book Chapters

This Article argues that persecution based on sexual orientation constitutes a crime against humanity under international law. Unlike other scholarship that has focused on the definition of crimes against humanity in the 1998 Rome Statute for the International Criminal Court—which does not explicitly enumerate “sexual orientation” as a protected classification—this Article looks to customary international law made up by the practices of states.

Diligent research has revealed that between 1998 and 2022, at least 107 states enacted laws or revised existing laws decriminalizing sexual orientation and/or categorizing sexual orientation as a protected classification from discrimination. This is in addition to …
