The British Women’S Land Army: Gender, Identity, And Landscapes, Hilary M.K. Anderson

Masters Theses

The land girls who comprised the Women’s Land Army in Great Britain during the Second World War challenged cultural assumptions regarding gender and femininity. Through their work in agriculture, social anxieties were provoked regarding proper notions of femininity and separate spheres, which left these women in conflicting positions as they carved a spot for themselves in a war torn society. In order to carry out their work in the Women’s Land Army, land girls operated at the convergence of private and public spheres in a conjoined space. Living and operating in this conjoined space enabled them to blur the ideological …

A Comparison Of Two Variations Of A Stimulus-Stimulus Pairing Procedure On Novel And Infrequent Vocalizations Of Children With Autism, Andrew J. Bulla

Masters Theses

Despite the growth in a behavioral technology for the treatment of autism, a small population of individuals with autism fails to develop functional language. One procedure used for inducing vocalizations in non-verbal children is a stimulus-stimulus pairing (SSP) procedure. In an SSP procedure a vocalization is paired with a reinforcer over a period of time to establish the vocalization as a learned reinforcer, and any utterance of the target vocalization is believed to be automatically reinforced thus increasing the frequency of the vocalization. Past research has yielded mixed results with the SSP procedure, and more research is warranted to identify …

Effects Of Road Salt On Asylum Lake Geochemistry, Davina A. Wyman

Masters Theses

Several studies indicate that seasonal applications of road deicers can lead to saline runoff entering surface water and groundwater, which can in turn change the chemistry, density, and physical mixing patterns of urban lakes. An investigation at Asylum Lake, an urban lake located near three major roadways, was conducted to determine the degree of road salt contamination in the lake, to determine if salt loading disrupts seasonal mixing patterns, and to determine the extent of redox stratification present due to eutrophic conditions. Samples were collected monthly from the deepest point in Asylum Lake over a 19-month period and analyzed for …

Wetland Sediment Nutrient Flux In Response To Proposed Hydrologic Reconnection And Climate Warming, James T. Smit

Masters Theses

Wetland restoration and creation are common practices, but wetlands restored or created on former agricultural land may act as a source of nutrients, rather than as a sink. I studied P sediment-water exchange in two flooded celery fields (west and east), which are designated for wetland restoration, in order to assess the effects that hydrologic reconnection of the area to an adjacent creek would have on P dynamics. We also examined the influence of climate change, specifically warming temperatures, by conducting the sediment-water exchange experiments at ambient and plus 2°C temperature conditions. Lab-based sediment core incubations revealed that TP release …

Exploration Of The Validity Of The Two-Dimensional Sagittal Plane Standing Long Jump Model, Lauren Hickox

Masters Theses

Most previous standing long jump studies have been based on the assumption of two-dimensional sagittal plane motion. The purpose of this study was to investigate the validity of this assumption. Standing long jump trials were collected using six adult male subjects. Each subject stood with a foot on each of two force plates and performed eight standing long jumps for maximal distance. Inverse dynamics analyses were performed for the two-dimensional (2D) and three-dimensional (3D) models and the joint moments, powers, and work values were compared. The differences between these models with respect to the validity of the common planar jumping …

Resting Site Characteristics Of American Marten In The Northern Lower Peninsula Of Michigan, Robert L. Sanders

Masters Theses

American marten are usually associated with forests that are characteristically late successional, closed canopy, and diverse in structure; attributes that meet habitat requirements and provide resting site structures. Resting site structures are required habitat components that are used daily and provide protection from predation and inclement weather. I identified resting site characteristics of American marten in the Manistee National Forest in Michigan’s Lower Peninsula from May 2011 to December 2013. Twenty five marten (15 male and 10 female) were monitored using radio telemetry to identify what types of resting sites structures were used. I identified 522 unique resting site structures; …

The Initial Effects Of Community Variables On Sand Prairie Restoration: Species Establishment And Community Responses, Robert Christopher Roos

Masters Theses

We established a sand prairie restoration experiment in northern Lower Michigan’s pine-oak barrens to analyze the effect of different community variables (vegetative cover, species richness, biomass, diversity, and floristic quality) when comparing: (1) how our restoration efforts (seeded treatments) compare to natural community succession (control plots), (2) how different seeding treatments affect these community variables, specifically when evaluating (2a) the effect of grass seeding densities; and (2b) the effect of different forb guilds (early flowering, late flowering, and legumes) during the initial two growing seasons of restoration establishment. In general, a comparison between seeded treatments and non-seeded control treatments indicates …

Turbellaria was the only taxa to have a significant positive relationship with zebra mussel density and biomass, Simuliidae had a positive, non-significant relationship with both. No macroinvertebrate taxa decreased because of zebra mussel density/biomasss. The other objectives of this study were to compare current macroinvertebrate communities in the Muskegon …

Historical Demography And Dispersal Patterns In The Eastern Pipistrelle Bat (Perimyotis Subflavus), Alynn M. Martin

Masters Theses

The recent emergence of threats to North American bat conservation has prompted increased population genetics research on high risk species. The eastern pipistrelle bat is affected by both white-nose syndrome and wind turbine mortality. However, little work has been done regarding the population structure and effective population size of this species. Using the HVI region of the mitochondria and eight microsatellite loci, I analyzed male and female structure across the sample range of P. subflavus and estimated the effective population size of their populations. Pairwise F_ST values indicate that there is one panmictic population based on microsatellite data, while …

Effects Of Health Expenditures On Population Age Distribution And Labor Force Participation Rates: Empirical And Comparative Analysis, Jassim M. H. Al-Jebory

Masters Theses

Baby boom and population aging are the main features of the world population that are leading to child and elderly people in the labor force. Categorizing the world into low and high-income countries, the baby boom and child labor can be found in low-income countries, while population aging and elderly people in the labor force can be found in high-income countries. The cause of these features is declining rates of population and labor force ages 15-64, which is the most productive and active proportion. Health expenditures is one of the main factors that is associated with undesired trends of population …

The Nucleic Acid Binding Properties Of The Pwi Motif, Hamideh Keshavarz-Mohammadian

Masters Theses

The PWI motif is a highly conserved domain that contains a Proline-Tryptophan-Isoleucine (PWI) tripeptide sequence, for which it is named. Proteins that contain a PWI motif are known to be involved in the constitutive and alternative splicing and the 3'-end processing of messenger RNA transcripts. The hypothesized role of the PWI motif is to nonspecifically interact with nucleic acids. The PWI motif is capable of binding both doublestranded and single stranded forms of DNA and RNA. The structure of the highly conserved core of the PWI motif reveals that it adopts a four-helix bundle fold. The structured core domain, however, …

Gpu-Accelerated Influenza Simulations For Operational Modeling, Peter Holvenstot

Masters Theses

Simulations of influenza spread are useful for decision-making during public-health emergencies. Policy-makers use models to predict disease spread and estimate the effects of various intervention strategies. Effective modeling of targeted intervention strategies requires accurate modeling of individual-level behavior and transmission. However, this greatly increases the computational costs of these agent-based models. In addition, if the models are used as an outbreak progresses, some operational decisions must occur rapidly in order to contain the spread of the disease.

Graphics Processing Units (GPUs) are a type of specialized processor used to drive graphical displays. Many recent devices also allow users to write …

Replacement Of Solvent Based Ink By Water Based Inks For Gravure Presses With Low Efficiency Ink Driers, Viraj Suresh Dalvi

Masters Theses

Rotogravure printing of decorative laminates, wall coverings, or vinyl floorings process often uses solvent based inks. The main constraining factor with solvent based ink is presence of volatile organic compounds (VOC’s). Due to the environmental norms on Volatile Organic Compounds (VOCs), and restrictions on using solvent based inks, the ink industry came up with water based ink as more environmentally friendly alternative. Organizations which print decorative laminates, wall coverings, or vinyl floorings with solvent based inks have gravure printing infrastructure, which is often equipped with low efficiency driers capable of drying solvent based inks. In order to comply with environmental …

Self-Supported Printed Multi-Layer Capacitors, Michael James Joyce

Masters Theses

The increasing demand for miniaturized electronic devices has increased the need for rechargeable micro-power sources. Although lithium and lithium ion batteries have been utilized in these applications since the late 1990s, other energy harvesting technologies, such as thermal, mechanical, and solar, are now being used to augment batteries to enable systems to be self-powered. However, the lifetime of any battery is finite, which may be a major problem when the application is in a permanent structure or medical implant device. For power or significant energy storage applications, printed multilayer capacitors or supercapacitors are being explored as an enhancement, or replacement …

From Verification To Guided-Inquiry: What Happens When A Chemistry Laboratory Curriculum Changes?, Pamela Sue Scott

Masters Theses

How does the degree or level of inquiry-based laboratory instruction impact student performance and student perseverance in the laboratory portion of a first-semester general chemistry course? In 2008, a two-year community college sought to answer this question by replacing the traditional verification laboratory curriculum with a guided-inquiry laboratory curriculum. This change provided a case study of the 'new' guided-inquiry curriculum vs. the 'old' traditional verification cuniculum. Researchers used a modified for college instruction version of The Continuum of Scientific Inquiry Rubric (Fay, Grove, Towns, & Bretz, 2007) to assess both laboratory curricula, to determine the level of inquiry incorporated into …

Genetic Analysis Of Ancient Human Remains From The Early Bronze Age Cultures Of The North Pontic Steppe Region, Jeff Pashnick

Masters Theses

During the Neolithic transition into the Early Bronze Age (EBA) in the North Pontic steppe region (NPR), people, cultures, and technologies were rapidly changing. Farming was on the decline and Indo-European languages were spreading through the region along with pastoralist way of life. In this study we used mitochondrial DNA (mtDNA) haplotyping to study the people living in the NPR during these times. Additionally, we used next-generation sequencing (NGS) technologies in attempts to develop novel methods to assess the degradation of ancient DNA (aDNA). We extracted ancient mtDNA from remains of 11 individuals belonging to late Neolithic and EBA populations …

Divine Sovereignty And Human Freedom: A Libertarian Approach, Daniel Shay

Masters Theses

Philosophers and theologians alike have debated endlessly over the relationship between divine sovereignty and human freedom. Too often, in these debates, human freedom is either denied altogether or reduced to a compatibilist notion. Many people fear that granting humans too much freedom would destroy God's sovereignty. However, the purpose of granting humans freedom is not to elevate the creature over the Creator; rather to uphold both moral responsibility and God's justice. Any theory that preserves God's sovereignty at the expense of His justice, or makes His justice arbitrary, by sacrificing the kind of freedom that preserves moral responsibility, is not …

Castlereagh At The Congress Of Vienna: Maintaining The Peace, Political Realism, And The Encirclement Of France, Nathan Curtis

Masters Theses

At the Congress of Vienna from September 1814 to June 1815, Stewart, the second Marquees of Londonderry and Viscount Castlereagh, succeeded in encircling France with a cordon of strong states that could better resist the possibility of future French military aggression. He conceived these goals with an eye towards European balance of power, strategically resettling European borders and placating allies when necessary. He guarded against the advances of France and Russia through the strengthening of the Low Countries, resettlement of Norway from Denmark to Sweden, the restructuring of a more resilient Italian Peninsula, and the division of Poland and Saxony …

The Generational Digital Divide: Understanding Adult Learners’ Self-Efficacy In Online Education, Justin Allen Melick

Adult learners are returning to higher education and frequently finding themselves in an e-learning environment, which may not have existed during their first stint in college. Online and blended classes often require students to complete technology tasks that they may not be confident performing. This thesis uses descriptive statistics to determine which tasks commonly used in online courses adult learners are least confident performing, giving institutions more …

Investigating Teachers’ Self-Reported Efficacy In Instructing Culturally And Linguistically Diverse Learners In Alternative Settings, Liane Kay Lancaster

Masters Theses

Teachers in alternative schools have limited to no knowledge of issues influencing students who are culturally and linguistically different. Current educational research lacks an in-depth examination of teachers’ perceptions of their use of culturally relevant practices with this group.

Using an adaptation of Siwatu’s (2007) Culturally Responsive Teaching Self-Efficacy Scale and drawing upon the theories of constructivism and multiculturalism, this study documents the perceptions of teachers’ preparedness in an alternative high school in the Midwest. The investigator collected information that may assist teachers and teacher preparation institutions in delivering instruction that better suits students who are culturally and linguistically diverse. …

Stratigraphic Framework And Landsystem Correlation For Deposits Of The Saginaw Lobe, Michigan, Usa, Ivan R. Guzman

Since the time of the Last Glacial Maximum (LGM) the south-central portion of the Lower Michigan Peninsula has been subject to several glacial advances and retreats by the Saginaw lobe. As part of the U.S Geological Survey Great Lakes Geological Mapping Coalition projects, several rotosonic borings were drilled between 2006 and 2013 in Barry, Kalamazoo and Calhoun Counties. Gamma ray logs and textural analyses were completed for each core. Five of these borings were selected according to their diamicton (till) content and correlated using water well logs and surficial geology maps. Glacial deposits such as diamicton serve as evidence of …

A Novel Silica-Based Nano Pigment As A Titanium Dioxide Replacement, Ryan Stoneburner

Masters Theses

This research focused on the evaluation of a new Silica-based pigment for the replacement of titanium dioxide (TiO₂) in paperboard coatings. The silica-based pigment has shown the ability to be a replacement in terms of functionality and runnability. TiO₂ is currently the highest opacifying pigment used in paper coatings, but it is also the most costly. Finding a less expensive pigment that doesn't reduce effectiveness is critical to reducing the cost of TiO₂ formulations. To evaluate the new pigment, coatings will be applied using a Cylindrical Laboratory Coater (CLC) with varying amounts of TiO₂ and …

The Social And Cultural Meanings Of Names In Late Antique Italy, 313-604, Eric Ware

Masters Theses

This thesis examines many uses of names in Italian culture and society between the years 313 and 604. Through an anthroponymic study of names in Late Antique Italy, I explore the relationships between names and religion, social groups, gender, and language. I analyze the name patterns statistically and through micro-historical studies. This thesis argues that, contrary to studies emphasizing the late antique decline of the Roman trinominal system, Italian names demonstrated continuity with classical onomastic practices. The correlations between saint’s cults and local names and the decline of pagan names suggests that saints’ names replaced pagan ones as apotropaic names …
