Identifying Barriers To Data Use On U.S. Beef Cow-Calf Operations And Developing Solutions To Improve Cow-Calf Record-Keeping, William Isaac Jumper

Theses and Dissertations

Cattle health and production records (CHPR) are data collected by cattle producers and veterinarians in the form of measurements, observations, counts of events over time, and physiologic attributes that describe individual and group-level health and production. These data are useful to both veterinarians and cattle producers for making evidence-based decisions on cow-calf operations. Currently, there are no uniform, industry-wide methods of capturing and recording CHPR in the U.S. cow-calf industry. Although many cow-calf producers in the U.S. are thought to collect some form of CHPR, it is believed that relatively few are doing so in an electronic manner that facilitates …

Northern Bobwhite (Colinus Virginianus) Breeding Season Calling Behavior And Roost Site Selection In A Working Agricultural Landscape In Clay County, Mississippi, Olivia A. Lappin

Theses and Dissertations

Research on northern bobwhite calling behavior and roosting ecology during the breeding season has received limited attention. However, variability in calling rate in response to conspecifics and environmental factors may affect avian monitoring strategies. We conducted 10-minute breeding season surveys (April-August) on B. Bryan Farms, Mississippi, from 2021-2022 to evaluate the impact of conspecifics and environmental covariates on male bobwhite calling rate. We observed a positive linear effect of conspecifics and temperature on calling rate. We did not find sufficient evidence to support a relationship between calling rate and cloud cover or barometric pressure. We also analyzed breeding season third-order …

Adaptive Large Neighborhood Search Algorithm – Performance Evaluation Under Parallel Schemes & Applications, Sandip Kumar

Theses and Dissertations

Adaptive Large Neighborhood Search (ALNS) is a fairly recent yet popular single-solution heuristic for solving discrete optimization problems. Even though the heuristic has been a popular choice for researchers in recent times, the parallelization of this algorithm is not widely studied in the literature compared to the other classical metaheuristics. To extend the existing literature, this study proposes several different parallel schemes to parallelize the basic/sequential ALNS algorithm. More specifically, seven different parallel schemes are employed to target different characteristics of the ALNS algorithm and the capability of the local computers. The schemes of this study are implemented in a …

Evolution And Epidemiology Of Channel Catfish Virus (Ccv), Arun Venugopalan

Theses and Dissertations

Channel catfish virus disease (CCVD) is the principal viral disease in the United States catfish industry. The CCVD is caused by channel catfish virus (CCV), with mortality reaching up to 100% in fingerlings. CCV is assigned taxonomically to the family Alloherpesviridae, genus Ictalurivirus, species Ictalurid herpesvirus 1 (IcHV-1). To date, virulence, immunogenicity, and genome plasticity of the CCV field isolates have not been investigated. Three genotypes of CCV (IcHV-1A, IcHV-1B, and BCAHV) were identified using restriction fragment length polymorphism (RFLP) analysis. Virulence assessment of three representative isolates of RFLP groups suggests that IcHV-1B (pooled survival [mean ± SE]: 58.3% ± …

Dynamic Role Of Exosome Micrornas In Cancer Cell Signaling And Their Emerging Role As Noninvasive Biomarkers, Jaya Aseervatham

Department of Neurology Faculty Papers

Exosomes are extracellular vesicles that originate from endosomes and are released by all cells irrespective of their origin or type. They play an important role in cell communication and can act in an autocrine, endocrine, or paracrine fashion. They are 40–150 nm in diameter and have a similar composition to the cell of origin. An exosome released by a particular cell is unique since it carries information about the state of the cell in pathological conditions such as cancer. miRNAs carried by cancer-derived exosomes play a multifaceted role by taking part in cell proliferation, invasion, metastasis, epithelial–mesenchymal transition, angiogenesis, apoptosis, …

Commentary On Return Preparer Obligations, Michael B. Lang

Florida Tax Review

A complex web of overlapping rules of law and professional ethics regulates the work of return preparers. Some of this complexity reflects the overall complexity of the tax system and the transactional activity to which it applies. Some of the complexity occurs because returns are prepared by members of different professions. The fact that preparers, depending on their professional status, are subject to discipline by the Director of Practice of the Internal Revenue Service, by the AICPA, by state bar and accounting regulatory authorities, under the penalty provisions of the Code, and perhaps through malpractice and contract law, is nonetheless …

End Of Life In The Ed – Brain Death And Organ Transplantation, Madison Cohen, Robert Griffin, Donald Penney

Research Day

Brain death is defined as the irreversible loss of all brain and brainstem functions. While the criteria for diagnosing brain death have been established and refined since 1995, physicians remain uncomfortable with making the diagnosis leading to delays in pronouncing the patient as brain dead. While seemingly benign, a delay in pronouncing a patient as brain dead can place a financial burden on the family and cause additional and unnecessary emotional distress. Furthermore, delayed pronunciation of death causes improper delegation of the medical care team's resources and loss of the patient's potential to serve as an organ donor. The purpose …

The Influence Of Nutrition On The Gut Microbiota And Psychiatric Disorders: A Review, Megha Bhagavan, Francis Jenney

Research Day

The symbiotic harboring of gut microorganisms within the gastrointestinal tract has a profound influence on host physiology, well-being, and disease pathology. More specifically, the gut bacteria are able to interact with dietary components from foods chosen by the host and consequently relay their beneficial or precarious effects locally and systemically. The gut bacteria have the capacity to maintain a healthy gut microbiome or perpetuate intestinal imbalance, known as gut dysbiosis. Gut dysbiosis has both local effects in gastrointestinal pathologies, such as intestinal bowel syndrome (IBS) and intestinal bowel disorder (IBD), as well as systemic pathologies, such as type II diabetes, …
