Title: THE PRODUCTION OF SPECTACLE : VERBAL AND VISUAL ELEMENTS IN SHAKESPEARE’S ANTONY AND CLEOPATRA
Creator: Lockwood, Gabrielle W.
Date: 2022
Collection: Electronic Theses & Dissertations
Description: As Shakespeare’s Antony and Cleopatra was first staged, much of Renaissance Europe was engaging in a debate around artistic production. Painting and poetry were set against each other to determine which could produce the best representation of nature or surpass it altogether. What we see with theater, however, is that it occupies a unique position in the world of artistic production because it is capable of presenting the two, seemingly opposite forms of representation: the verbal and the...
Show moreAs Shakespeare’s Antony and Cleopatra was first staged, much of Renaissance Europe was engaging in a debate around artistic production. Painting and poetry were set against each other to determine which could produce the best representation of nature or surpass it altogether. What we see with theater, however, is that it occupies a unique position in the world of artistic production because it is capable of presenting the two, seemingly opposite forms of representation: the verbal and the visual. Examining the discourse around art production in early modern England reveals how the construction of Antony and Cleopatra’s famous scenes reflects debates around representational mediums. Shakespeare’s interchange between verbal and visual representation produces shifting characterization of the play’s iconic figures. Since the two mediums work simultaneously to produce different images, the characters are often paradoxical and unpredictable. From here, it is possible to trace how Antony and Cleopatra’s distinctive characterization has become a cornerstone of its legacy. By looking at the production history of the play, it is apparent that its critical reception relies on a production’s awareness of shifting artistic mediums, complex representational choices, and paradoxical figures.

Show moreYear-round demand for locally sourced specialty cut flowers continues to increase in the U.S., but growers in northern regions cannot produce them outdoors or in high-tunnels year-round due to poor environmental conditions during the winter and early spring. Thus, they must use greenhouses to maintain a proper lighting environment to capitalize on demand during these seasons. Our objectives for Expts. 1 and 2 were to a) determine how photoperiod influences morphology of marigold ‘Xochi’ (Tagetes erecta), witchgrass ‘Frosted Explosion’ (Panicum capillare), and dianthus ‘Amazon Rose Magic’ and ‘Amazon Neon Cherry’ (Dianthus barbatus interspecific) young and finished plants, and b) quantify how photoperiod and daily light integral (DLI) influence floral initiation and quality of witchgrass and dianthus. For Expt. 3, we sought to quantify how supplemental radiation quality influences floral initiation and finished quality of three long-day specialty cut flowers. Marigold was harvestable when young plants were grown under photoperiods ≥11 h or a 4-h NI, and finished under 12-h photoperiods. Witchgrass was harvestable when young plants were grown under photoperiods ≥14 h or a 4-h NI, and finished under photoperiods ≥14 h. Dianthus was harvestable when young and finished plants were grown under 9- to 16-h photoperiods, or a 4-h NI. Additionally, cut flowers should be grown under a DLI of ≥10 mol·m–2·d–1. Godetia, snapdragon, and stock cut flowers should be grown under supplemental light with a spectrum similar to B20R85FR15 or a broad spectrum, for desirable crop quality and minimal developmental, visibility, and energy tradeoffs.

Title: OBSERVATIONS OF ATMOSPHERIC TURBULENCE DURING A LOW INTENSITY SURFACE FIRE
Creator: Seitz, Joseph Patrick-Thayer

Show moreAmbient atmospheric environment affects the growth and spread of wildland fires, whereas heat and moisture release from the fires and the reduction of the surface drag in the burned areas can significantly alter local atmospheric conditions. Previous studies have investigated this interaction between the fire and the surrounding atmosphere, but the majority of these experiments collected in-situ data at the fire-atmosphere interface using only a few instrumented towers in typically a large burn plot of at least a few acres or several thousand square meters. This study reports results from a recent prescribed surface fire experiment conducted on a small, densely instrumented burn plot of one hundred square meters (10 m by 10 m). The fuel in the burn plot was pine needles with a fuel loading of about 0.5 kg m-2 and fuel moisture of 5.5%. At the time of the burn, the ambient wind speed at the fuel bed level was about 2 m s-1. In-situ meteorological observations were collected using a 4 by 4 array of three-dimensional sonic anemometers mounted on four trusses at 2.5 m right above the fuel bed level. The analysis of the 10-Hz velocity and temperature data from the 16 sonic anemometers focuses on fire-induced atmospheric turbulence. By comparing the observations collected before, during and after the fire, the study reveals how the fire can alter the heat and momentum exchanges between the combustion zone and the atmosphere above. Besides confirming some of the general findings about fire-induced turbulence from previous studies, the results reveal the existence of substantial heterogeneity in the fire-atmosphere interactions across the burn plot. Even for a plot as small as this, the perturbations of the fire to the ambient atmosphere depends strongly on the downwind distance from the initial fire line and the specific position relative to the fire front. This key finding further highlights the necessity for fire behavior models to have 1-2 m grid spacing to resolve the heterogeneities and capture fire-atmosphere interactions that are relevant to turbulence. The results also have important implications for modeling smoke dispersion, as atmospheric dispersion characteristics in the vicinity of a wildland fire are directly affected by fire-induced turbulence.

Show moreBacterial canker of sweet cherry trees, caused by the bacteria Pseudomonas syringae pv. syringae (PSS), is an economically important disease in Michigan and effective disease management is not available. For these reasons, bacteriophages (phages) are being investigated as a potential biological control of bacterial canker. A cocktail of Pseudomonas bacteriophage was tested as a biological control in Michigan sweet cherry orchards during bloom in 2021 and 2022. Populations of antibiotic-marked pathogenic PSS strains were tracked for the duration of the flowering period. Establishment of PSS populations greater than 5 log10 CFU g-1 flowers were detected on all water treated flowers during the experiment. In one field replicate on sweet cherry variety ‘Benton’, the PSS population on flowers treated with the phage cocktail was lower (P<0.05) 48 hrs after treatment. Environmental conditions during this field experiment were different compared to the other replicates including higher precipitation, higher relative humidity, and lower Daily Light Integral. These observations could indicate conditions in which phage may be an effective biological control. It also corroborates the need for reducing phage degradation by UV in the field. Kaolin clay was tested as a protectant against UV irradiation in vitro and in vivo. A rate of 4.8 mg ml-1 kaolin clay was shown to effectively protect phage from UV degradation in vitro but was not observed when the phage cocktail was supplemented with kaolin clay in the field. This work gives us a better understanding of the potential of phage as a biological control of bacterial canker under field conditions.

Show moreThe use of sterile insect technique (SIT) for codling moth (Cydia pomonella L.) management has been proven successful at suppressing wild populations, allowing for the reduction of insecticide applications. Most of this research has occurred in British Columbia, Canada and Washington, United States. In this thesis, I demonstrate how this tool might be utilized in Michigan apple orchards. I first looked at how male and female C. pomonella respond to traps baited with different chemical cues in Michigan compared to Washington in a 2-year study. I found a difference in the sex ratios of recaptured codling moths between the two states, demonstrating that lure performance is different based upon regional differences. In addition to monitoring traps, I investigated how to apply sterile insect technique in Michigan where a farm-scale approach is necessary due to the relatively small size of orchards in this region. I compared the timing of releases during the season (1st generation, 2nd generation, or season long) in addition to the rate of moths released (half or full rate). The full rate released for first generation or season long had consistently low wild male moth captures throughout the season. Finally, we tested the method of the release (self-released, released in the canopy, or released on the ground) and found that there was no significant difference between the release methods tested. These results can inform future development of codling moth management programs for Michigan apple orchards that include the sterile insect release.

Show moreClonal hematopoiesis of indeterminate potential (CHIP) is a clinical entity of aging humans that is characterized by cancer-associated mutations in white blood cells, without evidence of overt neoplasia. CHIP has been associated with an increased risk of hematologic cancers, cardiovascular disease, and all-cause mortality. We hypothesized that somatic mutations in specific genes associated with human CHIP would be detectable in the blood of aged dogs not known to have hematologic disorders. DNA from paired germline and whole blood samples from 93 geriatric canine patients affected by solid cancer were subjected to targeted next generation sequencing. Impact of the variants was predicted using Polymorphism Phenotyping version 2 software (PolyPhen-2, Harvard). Clinical and demographic data were extracted from medical records. Somatic variants were detected in peripheral blood of four (4.3 %) female dogs aged 12-15 years. Affected genes were ASXL1, KIT, SF3B1, TET2, RUNX1, and PPM1D. The variant in PPM1D was a nonsense mutation, while the other five variants were single nucleotide non-synonymous variants in protein coding regions of the genes. The single nucleotide variants in KIT and SF3B1 were predicted to be benign, while the variants in ASXL1, TET2, and RUNX1 were predicted to be damaging. A mutant RUNX1 cell line was designed and constructed with CRISPR technology, and the mutant cells had an increased growth rate compared to controls. These results support the presence of variants in CHIP-associated genes in geriatric canids similar to those observed in people, and the dog represents the first species in which the genetic lesion of CHIP has been documented. Further investigations are needed to confirm the association of this genetic lesion with clinical outcomes.

Show moreThe lake sturgeon (Acipenser fulvescens; LST) is the only sturgeon species in the Great Lakes (GL), where populations are estimated to be <1% of historical abundances. Resultantly, substantial resources are being devoted to the hatchery propagation of LST. Concurrently, more is being uncovered regarding viral diseases that affect sturgeons (e.g. Frog virus 3 [FV3], Nucleocytoplasmic Large DNA viruses [NCLDVs], Acipenserid herpesviruses). To investigate the presence of these viruses, I collected wild adult and hatchery reared juvenile GL-LST (Lake Erie, Huron, Michigan, and Superior watersheds) and utilized specialized/specific molecular and in vitro diagnostics. Although FV3 and NCLDVs were not detected in sampled GL-LST, I successfully detected and, for the first time, isolated a herpesvirus (Family Alloherpesviridae) from adult GL-LST that, based on genomic analyses, appears distinct from known alloherpesviruses. To assess virulence of this virus (proposed name of lake sturgeon herpesvirus 2, LSHV-2), juvenile GL-LST were immersed in a viral suspension. Within 10 days, disease signs developed in virus-exposed LST, soon progressing to mortality (33% cumulative mortality), where LSHV-2 was re-isolated from representative skin lesions. Next, the efficacy of three disinfectants (Perox-Aid®, VirkonTM-Aquatic, and Ovadine®) against LSHV-2 was assessed in vitro, where all three substantially decreased viral titers to varying degrees, marking promising means of prevention/control. Whether LSHV-2 has or is contributing to reduced LST abundance in the GL remains to be determined, but my findings provide a foundation to further study and combat this newly uncovered sturgeon-pathogenic virus.

Show moreRehabilitation of lake trout (Salvelinus namaycush), which historically was the coldwater apex predator of much of the Laurentian Great Lakes, is a priority for fishery management agencies in the region. In Lake Erie, the shallowest and southern-most Great Lake, successful rehabilitation of lake trout has been hindered by limited wild recruitment, possibly related to the lake’s warm temperatures and restricted oxythermal habitat. I used acoustic telemetry tracking technology to investigate how lake trout spatial and thermal habitat use varies seasonally in Lake Erie to better understand whether limited recruitment could be caused by thermal conditions in the lake. As expected, lake trout were restricted to the offshore region of the eastern basin of Lake Erie during summer stratification. During fall, lake trout tended to occupy the southern nearshore region of the eastern basin, suggesting the importance of focusing spawning habitat restoration in this part of the lake. Tagged fish dispersed long distances at much higher frequencies than other Great Lakes populations of lake trout. Lake trout in Lake Erie occupied thermal habitat similar to other Great Lakes populations during summer stratification. Following destratification in fall, fish were exposed to warm temperatures, in some years for extended periods. Lake trout hatchery strains of Finger Lakes, NY, origin occupied similar summer temperatures and warm temperatures for more days during fall than Great Lakes origin strains, contrary to findings from Lakes Huron and Ontario. These results reveal behaviors that can inform management of lake trout in Lake Erie and throughout the Great Lakes and could begin to explain recruitment failure observed in Lake Erie.

However, there is little work on changes to wetland geomorphology, what those transformations may be, and how they impact the wetland. This paper aims to identify changes in wetland geomorphology and decern any correlation between water level and vegetation extents. Data for this study spans from 2012 to 2021, capturing the most recent period of rising water levels. Vegetation extent imagery and topobathymetric data were collected during field excursions in the summer of 2021 and compared to NAIP imagery acquired from USGS Earth Explorer and topobathymetric LiDAR data from NOAA Data Access Viewer. Imagery from 2021 was collected using a DJI Phantom 4 Pro quadcopter drone and 2021 topobathymetric data utilized an RTK-GPS antenna and Seafloor Systems SonarMite single-beam echosounder to conduct boating, kayaking, and wading surveys at each study site. Studies took place at Wigwam Bay and Quanicassee State Wildlife Areas located in Saginaw Bay of Lake Huron. Findings show water level had a variable impact on vegetation extent and suggest that erosion of sediment occurred during high water levels at both sites. Results show observable changes in geomorphology adjacent to the wetlands. Changes to geomorphology could potentially impact the size, health, and ecosystem services of coastal wetlands. This initial study has limitations due to the nature of available historical data but is intended as a first step towards further understanding the role of geomorphology in coastal freshwater wetland systems.

The commercially important cultivar ‘Honeycrisp’ is highly susceptible to the disorder. In-planta Ca transport occurs exclusively in the xylem; therefore, Ca deficiency in fruit is primarily the result of gradual xylem dysfunction. Because auxin promotes xylogenesis, we hypothesized that early-season applications of both native and synthetic auxins and ABA would improve xylem longevity and functionality resulting in higher Ca concentrations in fruit and reduced bitter pit. Using several experimental approaches, we demonstrate that auxins and ABA significantly prolong xylem function and markedly reduce bitter pit incidence. A multiple regression model was also developed to correlate temporal climatic data with bitter pit incidence over multiple years and disparate sites throughout Michigan. Collectively, results suggest potential novel uses of plant growth regulators to mitigate bitter pit.

Show moreABSTRACTThe Role of the Campus Outdoor Environment on University Student Mental Health: A Study Focusing on the Michigan State University CampusByMallory Marie Koning The mental health and wellness of university students has been a pressing concern in recent years in the US and is becoming an even larger issue due to the COVID-19 Pandemic. The main purpose of this study is to investigate the correlations between university student mental health and their campus’s outdoor environment. To gather data for this research, an online survey was designed based on literature review and distributed to students at Michigan State University. Students were asked questions about their overall mental well-being, as well as questions about their environmental perceptions, outdoor activity, views to nature through windows and safety concerns regarding their outdoor campus environment. Among 161 survey respondents, the major findings of this study indicate a significant difference in mental health scores for windows in living quarters, where students with living quarter windows had better mental health scores (MHS) than students without living quarter windows. This study also found a marginally significant difference in the MHS for students with classroom windows, where students with classroom windows had better mental health than students without classroom windows. These results also indicated a stronger need for windows in living quarters than on campus. Other results of this study include a significant difference in MHS for students’ perception of safety on campus, outdoor work time, and perception of greenspace on campus. Future landscape designers, university planners, and student counselors will be able to use this study to determine what kinds of outdoor spaces should be created and used to improve the well-being of students.

Show moreSince the 1990s, the United States has seen increased prescription opioid consumption (POC) and an increase in the prevalence of opioid use disorders (OUD) and the opioid disorder death (ODD) rate. This paper examines three factors that may have fueled the opioid crisis: increased supply of prescription opioids, increased demand for opioids because of pain and economic related despair. A regression analysis of twenty-one OECD nations was used to examine the determinants of and the relationships between POC, OUDs, and ODDs. Over 1991-2019, consumption did not have a significant effect on OUDs or ODDs, but over 2003-2019 it had a positive significant effect on both. These results held if the US was removed from the sample, supporting some supply side effect across the panels after 2003. Furthermore, OUDs have a large, positive and significant effect on ODDs, indicating two possible pathways direct (straight from consumption) and indirect (through an effect on opioid use disorders) that POC relates to increased ODDs. One model estimates that 39% of the increase in US opioid fatalities is attributable to increased POC between 2003-2010.

Show moreMichigan celery field and greenhouse yield and quality is negatively impacted by soilborne pathogens. Celery growers have observed a crown rot, wilt, and vascular discoloration called “meltdown”. Symptomatic celery plants were collected from seven grower commercial grower fields across four counties and two years. Isolations showed the most common organisms observed were Fusarium solani species complex (52%) and Fusarium oxysporum species complex (45%) as identified by sequencing of the translation elongation factor-1α. Isolates identified as Fusarium oxysporum f. sp. apii race 2 (Foa race 2), the cause of Fusarium yellows, using diagnostic primers caused disease in a growth chamber pathogenicity assay. Foa race 2 isolates are capable of causing disease symptoms but are infrequent so “meltdown” may have additional cause(s). Pythium root rot decreases quality of greenhouse grown celery transplants. Pythium spp. isolated from symptomatic celery seedlings were characterized by virulence and fungicides tested for control of Pythium root rot. The most frequent Pythium species collected from Michigan celery were P. mastophorum (55%), P. intermedium (16%), P. sulcatum (10%), P. aff. diclinum (6%), and P. sylvaticum (5%). P. sulcatum and P. sylvaticum caused disease symptoms on celery seedlings in a greenhouse virulence assay. Phosphorous acid salts, ethaboxam, and mefenoxam controlled Pythium root rot in a greenhouse setting. Results indicate which Pythium spp. are of most concern to celery growers and identify effective chemical controls. Understanding presence and virulence of soilborne plant pathogens in Michigan celery production will be used to develop strategies to limit disease.

Show moreWorldwide, women's contributions in the fisheries sector are significant and include fish harvesting, processing, and marketing, among others. However, women often face discrimination and are not recognized in the sector by their male counterparts, managers, and policymakers. This thesis aims to examine the motives for the establishment of women organizations in Indonesia, the Indonesian Fisherwomen's Sisterhood Group (Persaudaraan Perempuan Nelayan Indonesia/PPNI), and to investigate how the lives of women belonging to the organization have changed. This study is based on a qualitative case study using both primary and secondary sources. The primary data consists of interviews conducted via Zoom and phone interviews. This study adopts a Feminist Political Ecology (FPE) framework to examine barriers that women experience that led to the collective action to establish a women-specific fishery organization. Issues related to economic and environmental changes, lacking access to decision-making processes and resources, and lacking recognition were pivotal for women in the sector to organize themselves. This study found that being part of the organization can become a strategy for women in fisheries to overcome barriers in the sector. This study also shows that PPNI allows women in the sector to renegotiate their roles and rights within their households, communities and in the sector. Thus, since the establishment of PPNI, the organization has made efforts to foster gender equality, mainly to support changing women’s lives through women's empowerment.

The results show that that when compared with control samples of glulam, the glulam manufactured with 60% of salvaged lumber had a reduction of 10.5% in MOR, 10.5% in MFL, and 1.9% in MOE as shown in table 4.1. when compared with control samples of glulam the glulam manufactured with 40% of salvaged lumber had a reduction of 4.7% in MOR, 4.5% in MFL, and 1.35% in MOE. These reduction percentages are less than 11% for all mechanical properties. In other words, we can say that even for glulam samples made of 60% of salvaged lumber the reduction percentage for all mechanical properties is going to be less than 11%. The reduction percentage for MOE between two consecutive grades turns out to be 33% approximately so we can safely say in absence of any data about a given salvaged sample we can assume that MOE of that salvaged lumber will be one grade below the actual MOE of that sample before use.

Title: Data-Driven Modeling and Analysis of Residential Building Energy Consumption and Demand Flexibility
Creator: Kawka, Emily
Date: 2022
Collection: Electronic Theses & Dissertations
Description: Buildings are responsible for approximately 74% of total electricity consumption, the leading contributor of carbon dioxide emissions in the United States. As initiatives aim toward net zero emissions through electrification and clean energy, building energy efficiency measures are crucial to achieve this clean energy transition. Through measuring energy use, this increases the accuracy of building use assumptions, which drive how energy use reduction is investigated and targeted. As...
Show moreBuildings are responsible for approximately 74% of total electricity consumption, the leading contributor of carbon dioxide emissions in the United States. As initiatives aim toward net zero emissions through electrification and clean energy, building energy efficiency measures are crucial to achieve this clean energy transition. Through measuring energy use, this increases the accuracy of building use assumptions, which drive how energy use reduction is investigated and targeted. As disruptive events and technology shift how occupants use residential buildings, this has the potential to shift how they consume their energy. In this thesis, high resolution, disaggregated energy use data is used to model and analyze energy use for two specific disruptions: the COVID-19 pandemic and electric vehicles (EVs). The first study measures how COVID-19 impacted residential building energy use. The findings of this research indicate an increase in energy use for both weather-dependent loads and weather-independent loads during the COVID-19 pandemic. Additional analyses give insight to the pandemic’s impact by household income, demonstrating the lowest and highest income groups experiencing larger increases in consumption while remaining populations experienced smaller shifts. The second study analyzes residential EV charging behavior and models the maximum load reduction potential for demand response in the Midcontinent Independent System Operator (MISO) region. The results of this study indicate relatively consistent charging use patterns across a full year, weekend charging is more distributed throughout the daytime compared to weekday charging, and there are significant opportunities to reduce or shift EV loads during typical peak load periods.

Show moreEcohydrology links ecological and hydrological processes and considers interactions between water resources and ecosystems. Modeling tools are not only important for studying the mechanisms of ecological patterns and processes but also for assessing the effects of environmental change on hydrological and ecological processes, providing insights and solutions to issues in water management. This thesis explores various data-driven approaches to monitor and model these processes at 95 watersheds in western USA using a combination of seasonal and annual climate, hydrometric, and remotely sensed vegetation data. In one analysis, we show that a trend in earlier peak in spring vegetation activity may be a linked to reduced runoff availability during drought years compared to non-drought years. We also provide evidence that increase drought severity is consistent with a decrease in runoff ratio in forested catchments through regression analysis, supporting the hypothesis that the relationship among water-balance components may shift during drought events. In another analysis, we show that the type and amount of vegetation coverage, among other catchment characteristics, can affect the accuracy of data-driven runoff models. These results suggest that a better understanding of the ecohydrologic processes and characteristics is vital to development of effective long-term strategies to improve the resilience of watersheds.
