This thesis broadly theorizes how to make writing centers more accessible for disabled writers. Specifically, it applies a critical disability studies methodology both to writing center history and research practices. Importantly, this thesis resists impairment-specific approaches to accessibility, and instead seeks to develop the theoretical framework necessary to create lasting reforms in writing center theory and practice so that disabled people are included in both.

Show moreThis thesis broadly theorizes how to make writing centers more accessible for disabled writers. Specifically, it applies a critical disability studies methodology both to writing center history and research practices. Importantly, this thesis resists impairment-specific approaches to accessibility, and instead seeks to develop the theoretical framework necessary to create lasting reforms in writing center theory and practice so that disabled people are included in both. Central to this thesis is the idea of "rhetorical normalcy," which is a set of social, behavioral, and rhetorical codes that constitute the deleterious norms that both writing center studies and the larger field of rhetoric and composition have relied on throughout their history. A major claim throughout this thesis is that writing center history, theory, and practice all rely on this conception of rhetorical normalcy, often at the cost of writers with disabilities. Ultimately, this thesis argues that in order for writing centers to become radically accessible for writers with disabilities, writing center administrators and practitioners must first become aware of the role of rhetorical normalcy has always played in writing center practice, and they must look for ways to incorporate disabled writers into their theorizing and research about writing.

Michigan's diverse agricultural landscape provides multiple perspectives when considering the need for beginning farmer training. One perspective is a $104 billion industrial agricultural industry, with an ageing and decreasing farming population, and consolidation of land (MDARD, 2019). Another perspective is a growing movement of smaller-scale, regenerative farms with an emphasis on direct marketing, minimizing external inputs and improving ecosystem services. In the middle is an emerging...
Show moreMichigan's diverse agricultural landscape provides multiple perspectives when considering the need for beginning farmer training. One perspective is a $104 billion industrial agricultural industry, with an ageing and decreasing farming population, and consolidation of land (MDARD, 2019). Another perspective is a growing movement of smaller-scale, regenerative farms with an emphasis on direct marketing, minimizing external inputs and improving ecosystem services. In the middle is an emerging population of passionate and inexperienced growers that need training to get started, and farmer training organizations with their own challenges to meet farmers' needs. The purpose of this descriptive study was to survey Michigan's beginning specialty crop farmer training organizations in order to inform educators, policy makers, and beginning farmers. The research provides a description of existing training programs, the types of farmers participating in those programs, and current collaborations among the organizations. The results showed that Michigan has a diverse number of training options, but most operate independently of each other and lack resources to provide the best possible services. Recommendations include developing a state-wide systems approach to training and developing a central body or network that will aid in collaboration, resource allocation, and policy development. With this research as a foundation, it will be possible to complete a more comprehensive analysis, and to begin building a network that will provide future farmers to meet Michigan's agricultural challenges.

It has recently been discovered that some, if not all, classical novae emit GeV gamma-rays, but the mechanisms involved in the production of the gamma-rays are still not well understood. We present here a comprehensive, multi-wavelength dataset---from radio to X-rays---for the most gamma-ray luminous classical nova to-date, V1324 Sco. Using this dataset, we show that V1324 Sco is a canonical dusty Fe-II type nova, with a reddening of E(B-V) = 1.16 +\- 0.12, a distance > 6.5 kpc, a bulk ejecta...
Show moreIt has recently been discovered that some, if not all, classical novae emit GeV gamma-rays, but the mechanisms involved in the production of the gamma-rays are still not well understood. We present here a comprehensive, multi-wavelength dataset---from radio to X-rays---for the most gamma-ray luminous classical nova to-date, V1324 Sco. Using this dataset, we show that V1324 Sco is a canonical dusty Fe-II type nova, with a reddening of E(B-V) = 1.16 +\- 0.12, a distance > 6.5 kpc, a bulk ejecta velocity of 1150 +/- 40 km/s and an ejecta mass of 2.0 +\- 0.4 * 10^-5 M_{Solar}. However, despite its seeming normalcy, there is also evidence for complex shock interactions, including the aforementioned gamma-rays and early time high-brightness temperature radio emission. To explain how a nova can be simultaneously ordinary and have the highest gamma-ray luminosity to date, we present a simplified model of the ejecta in which the strength of gamma-ray emission is set by properties of a fast ejecta component that collides with a slower component to produce shocks. We conclude this detailed study of V1324 Sco by showing how it has helped shape our understanding of the role of shocks in novae. Along with the study of V1324 Sco, this work also presents detailed methods for determining the reddening, distance, and filling factor of a classical nova from optical spectroscopy (using V1324 Sco as an example). We also provide detailed derivations for fitting nova radio light curves, to determine ejecta mass and velocity.

Show moreThe relationships between Japanese gardens and Chinese gardens have been studied and discussed for a long time. This study focuses on the topic by a quantitative method. A cluster analysis is conducted to define the similarities and differences between these two kinds of gardens. The distinctive varieties in the result shows the elements that presents the relationships most distinctively. For this study, the data is collected in both Chinese gardens and Japanese gardens in order to show more persuasive results illustrating the relationships between these gardens. Principal component analysis is used to analyze the data, and to show intuitional visual results by graphs. The statistic software output shows a set of principal components. First three principal components contain roughly 59% of the variance. The design elements that distinctively effect the relationship are also indicated in the results, which lead further interpretation about the topic. The scatter graph shows distinct differences between Chinese gardens and Japanese gardens. Major elements divided Chinese gardens and Japanese gardens, traditional gardens and modern gardens, and Japanese gardens. This research can be used by garden designers and researchers to gain a insight concerning of the similarities and differences between Japanese gardens and Chinese gardens.

Pressure ulcers (PUs), also known as pressure sores, are localized damage to the skin and underlying tissues, usually occurring over a bony prominence and caused by sitting or lying in one position for long time. PUs are a detriment to the well-being of people who lose their mobility either permanently or temporarily, and high morbidity and mortality are associated with PUs. Although the initiating mechanism of PUs is still unclear, it is commonly accepted that internal normal and shear...
Show morePressure ulcers (PUs), also known as pressure sores, are localized damage to the skin and underlying tissues, usually occurring over a bony prominence and caused by sitting or lying in one position for long time. PUs are a detriment to the well-being of people who lose their mobility either permanently or temporarily, and high morbidity and mortality are associated with PUs. Although the initiating mechanism of PUs is still unclear, it is commonly accepted that internal normal and shear stresses, due to the presence of unrelieved external loads, play a central role in the formation and development of these wounds. Despite the significance of internal stresses in PUs formation, interfacial pressures, which are a surface measure of stress, are the indicators commonly used to develop practices and protocols to minimize loading on the soft tissue. However, no direct correlation exists between interfacial pressure and internal stresses of soft tissue. Therefore, tools and methods that can show internal distributions of soft tissue's stresses and strains as a response to external loading are needed.The ability of finite element (FE) models to accurately represent the anatomical structure of the leg and buttocks area and to estimate the localized stress/strain fields within highly deformable media, makes them powerful tools to investigate soft tissue response to external loadings. Despite the significant advancement previous studies have achieved, there are still important aspects in human thigh-buttock soft tissue modeling area that need to be improved. Two challenges are identified in this dissertation: 1) Microstructurally motivated skin modeling for an individual skin layer in finite element model. 2) Parameters estimation associated with large deformations.To address the first challenge, a microstructurally based constitutive model is proposed to describe the mechanical behavior of skin. The constitutive model incorporated the distribution of collagen fiber bundle orientations and relative collagen content measured from histology, and shows good agreement with the tensile test data.To address the second challenge, an optimization procedure that is able to match nonlinear behaviors between FE simulation and in vivo experimental data is developed. The difference between 3D and semi-3D model is quantified, and the accuracy of four commonly used constitutive model representing soft tissue nonlinear mechanical behavior is compared.Finally, a thigh FE model that has detailed anatomical representation of different soft tissue types, i.e., skin, fat, and muscle, is developed. The subject-specific in vivo experimental data are used to inform the optimization procedure to obtain best-fit constitutive parameters for different soft tissue types. The research in this dissertation provides an approach to describe the in vivo mechanical behavior of soft tissues in thigh-buttock area accurately through FE modeling. The constitutive parameters informed by in vivo data in this dissertation are valuable to facilitate future FE modeling studies to achieve accurate internal stress/strain distribution of soft tissues in thigh-buttock area.
