The Effect Of Different Warm-Up Durations On Subjective And Objective Measures Of Singing In Choral Singers Over The Age Of 55, Jeremy A. Chesman Jan 2023

The Effect Of Different Warm-Up Durations On Subjective And Objective Measures Of Singing In Choral Singers Over The Age Of 55, Jeremy A. Chesman

MSU Graduate Theses

Choral singing is a popular activity in the United States. Choral singers are often encouraged to warm up vocally before they sing. Considering voice conditions, like presbyphonia, that can develop shortly after retirement, more research about vocal warm-ups is needed for those over the age of 55. This study assesses the effects of various durations of vocal warm-ups on subjective and objective measures of the singing voice using a within-groups design with randomized condition order. Nine participants performed vocal warm-ups for 0, 5, 10, and 15 minutes. A song sample was then recorded and sent to two expert raters who …

Domesticity And Religion: Women In Italian American Literature And Culture Of The 1930s, Madeleine J. Kirkpatrick

MSU Graduate Theses

The lives of Italian American women of the early twentieth century have been documented in fragments in histories of immigration and in the literature written by the children of first-wave immigrants. This documentation often leaves an incomplete picture of how Italian women lived and moved in their new American context in the first decades of the twentieth century. This thesis examines Pietro Di Donato’s portrayal of Annunziata in his 1939 novel Christ in Concretealongside the journals of Elba F. Gurzau, a real-life, second-generation Italian woman living in New York City during the 1930s. By holding these women up next to …

Examining The Immune Regulation Of Nlrp12 Through Novel Protein Interactions, Catherine Rippe Jan 2023

Examining The Immune Regulation Of Nlrp12 Through Novel Protein Interactions, Catherine Rippe

MSU Graduate Theses

NOD-like receptors (NLRs) are intracellular proteins that play an important role in the regulation of the innate immune response to pathogens. Since being identified, various functions for NOD-like receptor pyrin domain containing 12 (NLRP12) have been suggested. It has been shown to negatively regulate the inflammatory response through canonical and noncanonical NF-kB signaling pathways, control tumorigenesis and gut homeostasis and exacerbate inflammation through the formation of a multi-protein complex called an inflammasome. Due to the varying roles established for NLRP12, the mechanisms by which it functions remain poorly understood. In this study, I sought to confirm a novel protein-protein interaction …

Intraspecific Hybrid Identification Of Black Walnuts Via Marker Assisted Selection, Makenna B. Thompson Jan 2023

Intraspecific Hybrid Identification Of Black Walnuts Via Marker Assisted Selection, Makenna B. Thompson

MSU Graduate Theses

The improvement of Eastern black walnut (Juglans nigra L.) cultivars could increase market expansion. Improved cultivars with superior qualities would increase profitability for both the seller and the buyer. Agronomically and economically important traits such as heavier nut weight, disease resistance, tree structure integrity, and yearly nut production can be efficiently improved by breeding black walnuts via marker-assisted selection. Microsatellite/simple sequence repeat markers were used in this research to determine potential intraspecific hybrids between ‘Football’ and ‘Sparrow’ cultivars. Intraspecific is defined as of the same genus and species. This quality makes it more difficult to identify hybrids because the parent …

Creating The Pause: A Theoretical Approach To Helping Students Achieve Creative Independence, Amanda J. Anderson Jan 2023

Creating The Pause: A Theoretical Approach To Helping Students Achieve Creative Independence, Amanda J. Anderson

MSU Graduate Theses

This paper will detail how the 2020 Covid-19 pandemic revealed the need for a modification of our current educational best practices. This modification asks that teachers create an intentional Pause where students can spend time dwelling on content and making their own meaning before teachers intervene through scaffolding and front loading. It uses a combination of personal experience, review of best practices, and Covid-19 data to show that best practices did not transfer well during the pandemic. It will then provide evidence for the addition of the Pause as well as addressing anticipated counterarguments.

A Part From You, Kenneth Rick Briggenhorst Jr. Jan 2023

A Part From You, Kenneth Rick Briggenhorst Jr.

MSU Graduate Theses

I invite empathy through art that is technologically assisted to find alternative interpretations for nontheologically informed faith. The sudden passing of my dearest friend, Jimmy, encouraged me to dig through my archives of data, to cherish all the bytes that remain of him. In this endeavor, I find that death is not the end, but a post-physical state of being. I express this sentiment in a part from you, where the work utilizes inanimate constructs to place your faith in, to make sense of the complexities of grief in a digitally tethered way of life. This life that allows many …

Tissue And Sex-Dependent Regulation Of Innate Immunity And Rna Editing In Mice, Kelsey R. Kendrick Jan 2023

Tissue And Sex-Dependent Regulation Of Innate Immunity And Rna Editing In Mice, Kelsey R. Kendrick

MSU Graduate Theses

Inflammation occurs as a result of insult or infection within the body. Individual cells respond to inflammation by upregulating genes that help mediate the immune response, such as ADAR1. ADAR1 helps regulate the immune response but also catalyzes a process called RNA editing. RNA editing alters the sequence of select mRNAs to alter the encoded proteins. The result is altered function of the encoded protein, which is often beneficial for the cell. Our goal was to determine how inflammation affects the function of ADAR1. Since we know that the effects of inflammation vary between different organs and sexes, we examined …

Quantitative Song Variety In Relation To Genotype In A Hybridizing Chickadee Population, Shelby Madison Palmer Jan 2023

Quantitative Song Variety In Relation To Genotype In A Hybridizing Chickadee Population, Shelby Madison Palmer

MSU Graduate Theses

The Black-capped chickadee (Poecile atricapillus) and Carolina chickadee (P. carolinensis) are North American songbird species that hybridize in a narrow contact zone stretching latitudinally from New Jersey to Kansas, USA. The association between genetic ancestry and song type in this hybrid zone has been studied independently several times and found to be minimal or absent, likely due to the influence of cultural transmission on learned song in the oscine passerine clade to which the chickadees belong. Despite this, the song of both species remains remarkably distinct in allopatry, suggesting a genetic constraint on certain qualities of …

Impact Of Sample Conditions On Dna Phosphodiester Backbone Bi/Bii Conformational Equilibrium Dynamics, Autumn C. Pilarski

MSU Graduate Theses

DNA damage, such as single base lesions and mismatches, is highly prevalent within cells. If these DNA damage events are not repaired, they could lead to mutations and thus disease and cancer. Intricate repair mechanisms are in place to fix these damage events, one such being Base Excision Repair (BER) and associated enzyme: Thymine DNA Glycosylase (TDG). The first step of this repair process, recognition of the lesion by TDG, is not well understood. The following thesis presents results to better understand the fundamental biophysical question of how a DNA lesion within a mismatch context is recognized in a million …

Renewable Fuels: Molecular Dynamics Investigations Into Pyrolysis Of Methyl Linoleate, Elson Osakpolor Eguaosa Jan 2023

Renewable Fuels: Molecular Dynamics Investigations Into Pyrolysis Of Methyl Linoleate, Elson Osakpolor Eguaosa

MSU Graduate Theses

With the rapid depletion of the world’s supply of fossil fuels, especially petroleum products, petroleum prices have risen by approximately 800% between the 1970s and now and are projected to continue rising. It is also expected that the world’s consumption of energy will increase commensurate with its growing population. Although biodiesel is a good renewable alternative, it has its limitations including high production costs and poor low-temperature performance. We seek to improve conventional biodiesel with pyrolysis to produce low molecular-weight compounds with high energy densities. Understanding the pyrolysis path on the atomic scale is key as it will allow us …

Invisible Monsters: Chuck Palahniuk’S Transgressive Look At A Hyperrealized Society, Jordan R. Trevarthen Jan 2023

Invisible Monsters: Chuck Palahniuk’S Transgressive Look At A Hyperrealized Society, Jordan R. Trevarthen

MSU Graduate Theses

By critically analyzing Chuck Palahniuk’s Invisible Monsters, I was able to conclude that the transgressive portrayal of hyperrealized consumerism warranted a close examination into the value American society places on an individual’s ability to replace authenticity for consumer obedience. Palahniuk’s dangerous representation of the body throughout the novel serves to highlight numerous ways in which a consumer transgresses against their own physical and mental well-being to achieve happiness constructed by capitalistic agendas. By using French theorist Jean Baudrillard’s concept of hyperreality in connection with gender, disability, and feminist theory and ecocriticism, I attempt to deconstruct the neoliberal ideology to which …

Sex-Dependent Effects Of Induced Acute Inflammation On Glucose Homeostasis And Rna Editing Enzymes, Christian A. Rivas Jan 2023

Sex-Dependent Effects Of Induced Acute Inflammation On Glucose Homeostasis And Rna Editing Enzymes, Christian A. Rivas

MSU Graduate Theses

The first line of defense against bodily insults, like pathogen invasion, is the innate immune system. Innate immunity sets in motion countless cascades that result in inflammation. Inflammation simultaneously affects multiple biological processes like metabolism and gene expression. Males and females react differently to inflammation. To understand both molecular and physiological sex differences in inflammation, we examined how inflammation affects gene expression and glucose metabolism. Adenosine deaminase acting on RNA (ADAR1) is upregulated by inflammation and catalyzes RNA editing, a process where nucleotides encoded by the genome are modified. ADAR1 also controls the innate immune reaction by decreasing activity of …

Influence Of Cell Cycle On Aim2 Inflammasome Activation, Ashok Kumar Dubey Jan 2023

Influence Of Cell Cycle On Aim2 Inflammasome Activation, Ashok Kumar Dubey

MSU Graduate Theses

A cell cycle's progression has a significant role in the development of a disease. All the signaling pathways and inflammatory reactions are maintained in a healthy mode if cell cycle checkpoints are precisely regulated and kept in homeostasis. AIM2 inflammasome is a cytoplasmic double-stranded DNA sensor. Upon activation, it elicits an inflammatory reaction with the release of pro-inflammatory cytokines such as IL-1β and IL-18 and they are cleaved by the proteases, Caspase-1 from their inactive form. Also, the AIM2 inflammasome helps in regulating cell division and inhibits cell proliferation; thus, leading to a cell death called pyroptosis. Here, I examined …
