An Examination Of Specific Learning Disability Identification Post Participation In The Michigan Department Of Education Transformation Zone, Erin E. Senkowski

Dissertations

The identification of students with specific learning disabilities has evolved since the reauthorization of the Individuals with Disabilities Education Improvement Act (IDEIA) in 2004. This reauthorization gave state agencies parameters that disallowed using the severe discrepancy model for identification as a stand-alone method. In response to this change, Michigan provided Intermediate and local school districts with further guidance that disallowed the use of the severe discrepancy model for identifying children with Specific Learning Disabilities (SLDs) and instead required Intermediate School Districts, on behalf of their local districts, to choose one of three models, including Patterns of Strengths and Weakness (PSW), …

New Alternative Method Developed For The Measurement Of Active And Total Clay In Foundry Green Sands, Piao Jian Tan

Dissertations

Precise measurement of active clay content in molding sand is essential in the metal casting foundry to produce high quality end products with no defects. The historical methylene blue (MB) test was considered qualitative, subjective and prone to operator bias in regard to the reading of the halo. A new spectrophotometric or digital clay technique has been developed. The test utilizes the cation exchange capabilities of the Cu(II)-triethylenetetramine dye and the absorbance reading of the sequestered solution through a UV-Vis spectrophotometer. Working with multiple laboratories (Decher, MTI, EJ, and JD) on actual foundry green sand samples, the method was optimized …

Three Essays On Fertility Rates In China, Lichun Cai

Dissertations

China is currently facing the issue of low fertility rates. In three chapters, I discuss the reasons for the low fertility rate in China from three different microeconomics perspectives, by using econometric methods including machine learning tools.

Chapter One considers the effects of income on fertility rate. There is a widely accepted view that the improvement of the education level has led to a decline in fertility. I critique this view and propose a new perspective: the childbirth choice of a family member is not only related to the education level, but also to the differences in education level between …

A Case Study Of The Organizational System Of Articulation At A Midwestern Regional Public University, Katherine J. Giardello

Dissertations

Quantitative research has long shown lagging community college transfer student completion rates, in addition to excess credits earned and lengthened time-to-degree for transfer students that do earn a bachelor’s degree (Horn & Skomsvold, 2011; Jenkins & Fink, 2016; Simone, 2014; U.S. GAO, 2017). Scant qualitative studies exist related to student transfer, particularly the academic enterprise of articulation and the university perspective on transfer.

This qualitative study takes up the cause, using organizational and systems theories (Birnbaum, 1988; Clark, 1983; Cohen & March, 1974; Morgan, 2006; Senge, 1990; von Bertalanffy, 1972; Weick, 1976) to frame a single site case study with …

Systematics, Biogeography, And Floral Trait Evolution Of The Plant Genus, Medinilla (Melastomataceae), John Peter Quakenbush

Dissertations

Medinilla is a large paleotropical genus in the plant family Melastomataceae with a long history of systematic uncertainty. The first objective of this research is to test the monophyly of Medinilla. A species tree is estimated using 599 nuclear gene trees, and 87 concatenated chloroplast genes are used to estimate the plastid phylogeny. Sampling includes 272 Medinilla and outgroups. Pachycentria and Plethiandra are resolved within Medinilla. Other fleshy-fruitedgenera long associated with Medinilla (i.e., Catanthera, Heteroblemma, Kendrickia) belong to other clades. With this new evolutionary framework, an infrageneric classification system is proposed for Medinilla consisting of …

School principals are facing an increase in demand and challenges from district, state, and federal agencies for improvements both behaviorally and academically. Each year, more school principals exit their positions for other professions. The concentrated poverty school districts have been hit the hardest by this exodus.

The purpose of this basic qualitative study is to examine why some principals within concentrated poverty school districts remain in their positions, especially when they are located near other districts with much lower poverty concentrations. The factors of interest are issues such as district leadership support for principals, compensation, climate and culture of the …

Beneficial Effects Of Exercise On Glial Cell Line-Derived Neurotrophic Factor Content And Endplate Morphology In Skeletal Muscle Of Aging Male And Female Rats, Juliana M. Vangyseghem

Dissertations

Premenopausal women display lower incidence and severity of neurological disease compared to men of the same age, yet these populations are often treated similarly. A decline in neuromuscular function is associated with aging, which may be partially explained by a decline in neurotrophic factor expression with age. A possible way to maintain neuroprotection would be to regulate the production and release of a target-derived neurotrophic factor, such as glial cell line-derived neurotrophic factor (GDNF). GDNF has been shown to be the most potent survival factor for motor neurons and GDNF content of skeletal muscle has been shown to increase with …

Development Of Enzyme-Based Biotechnology For Removing Stickies And Regaining Fiber Quality In Paper Recycling, Yun Wang

Dissertations

Producing paper with recycled paper consumes about 30-70% less energy and emits less GHG than using virgin wood. However, with current recycling practices, more foreign matters are commingled with the recycled paper including hot-melt adhesives, food residues, inks, resins/sizing agents, and coating adhesives, which result in stickies issues in the paper remanufacturing process. On the other hand, recycled fibers inherently have lower quality due to mechanical treatment, heating, chemical processing, and aging in various types of application/use of paper products, limiting the production of high-quality paper grades from recycled fibers. The goal of this dissertation research is to address both …

An Analogue Study Of Expected Working Alliance And Hope With Victims Of Military Sexual Trauma Among Civilian And Military-Oriented Therapists, Alishia D. Salyer

Dissertations

Victims of military sexual trauma (MST) face unique challenges as they pursue mental health treatment and supportive care. Understanding what factors impact potential treatment outcomes is critical in aiding in their recovery (Castro et al., 2015; Kroviak, 2020). Although a substantial amount of research has been conducted to evaluate prevalence and client factors associated with treating victims of MST (Teit et al., 2015; Turchik & Wilson, 2010), little is known about therapists’ factors including therapists’ expectations working with such clients. The purpose of this study was to examine the relationships between therapist type (military-affiliated versus civilian), therapist gender, client gender, …

Opportunity That Transforms Lives: Exploring The Lived Experience Of Graduates From A New Community College In The Dominican Republic, Sally Joslyn Peña Martinez

Dissertations

This qualitative study explored the lived experiences of graduates from a recently established community college in the Dominican Republic (DR). The study sought to understand from graduates' perspective the influence of completing an associate degree at the first Dominican Community College, Instituto Técnico Superior Comunitario (ITSC), and if their experience was transformative. Enrolling in higher education initiates a potentially transformative journey, consciously or unconsciously (Taylor et al., 2000). These changes stem from personal reflections on new experiences, forming new beliefs and assumptions that infill life with new meaning (Brookfield, 1984; Mezirow, 1978). This phenomenon is evident in community college students …

A Phenomenological Investigation Of The Meaning Making Experiences Of Christian Women Who Had An Abortion, Anne E. Stocker

Dissertations

Whether or not a woman should have an abortion is a hotly debated topic, and little information is known about how women make sense of their abortion experiences. Even less is known about how women make sense of abortion experiences in the context of their religious or spiritual belief system. This qualitative study explores the phenomenon of how women who have had an abortion make meaning of their abortion experience in the context of their Christian identity. This phenomenon was explored via research questions related to a woman’s experience of having both an abortion history and a Christian identity, how …

Investigating The Critical Literacy Practices Of Adult Learners: A Case Study Of Four Leveled Reading Courses At A Community College, Anna Fontaine

Dissertations

This study investigates the critical literacy practices of adult learners at a community college. Student participants were selected from four different leveled reading courses. In this study, four guiding questions were adopted from Klenner and Sandretto (2011): (1) How do students make personal connections to text?; (2) In what ways do students identify multiple points of view in the text?; (3) In what ways do students identify where people in the text and included or excluded from social situations?; (4) In what ways do students discuss the influences the text has had on their views of society? These four questions …

Measuring Multicultural Competence In Counseling, Martha Mae Golubski

Dissertations

Pedersen (1999) described multicultural counseling as the “fourth force” in psychology. The description is used to imply that multiculturalism is the next theory to understand human behavior, complementary to the other three forces: psychodynamic, behavioral, and humanistic explanations. Despite the attention being given to multiculturalism, professional organizations, training institutions, and service providers are still trying to understand what it means to have competency in multicultural counseling. Researchers have made decades of efforts to define and measure multicultural counseling competence; yet, there is still limited data about how multicultural training efforts influence these competencies and how counselor multicultural competency affects clients’ …

Adaptive Instruction Through Reflection: How Preservice Teachers Create And Implement Individualized Literacy Lessons In A University Reading Center, Jennifer Marie Lennon

Dissertations

Modern classrooms are increasingly diverse. Students vary in their academic abilities, personal interests, cultural and linguistic backgrounds, and previous experiences (Allen et al., 2013). To meet the varied needs of students, educators must adapt their instruction so all are able to find success. Modifying lesson plans and changing instruction based on student needs are forms of adaptive instruction (Hoffman & Duffy, 2016; Vaughn, 2019). This study explored the metacognitive processes of preservice teachers (PSTs) as they implemented adaptive instruction within their literacy lessons in a university reading center tutoring program. Adaptive instruction was examined through two lenses: first, as PSTs …

Synthesis Of Glucomannan-Xylan Composite Biofilms: Characterization And Applications For Food Packaging, Kholoud Al-Ajlouni

Dissertations

Scientists are most concerned about the need for green alternatives for efficient food packaging polymers to replace petroleum-based packaging products. The waste of corn cobs and the roots of the konjac plant contain hemicellulose, xylan and glucomannan respectively, and can be used to produce biofilms for food packaging.

The aim of these studies is to formulate biofilms from glucomannan-xylan blends that compete with petroleum-based plastic wrap. The biofilms must be strong, smooth, transparent, have a water vapor barrier, have the required mechanical properties and be cheap. Biofilms from glucomannan were stiff, lacked mechanical properties, and absorbed moisture. Therefore, it reacts …

The Effects Of Adolescent Trauma, Mental Health Treatment, And Demographic Variables On Educational Outcome, Christopher Postema

Dissertations

Poor educational performance in adolescence can occur due to trauma, substance use, or other stressors. This study used conflict theory as a foundation, suggesting differences in educational outcomes can be attributed to systems perpetuating the current power structures that cause inequality in academic opportunities and performance. Trauma in adolescence can have adverse effects on educational outcomes and emotional stability. Research suggests that mental health therapy as well as a reduction in trauma symptoms can improve educational outcomes. Race, gender, substance use, socioeconomic status, and employment are important variables that could influence educational outcomes. Interaction terms were found in the literature …

Analysis Of Trauma Screening As A Potential Predictor Of Congregate Care Placement As A Key Factor In Caseworker Decision Making, Amy Louise Perricone

Dissertations

The placement of foster care children into congregate care (CC) facilities has been debated regarding whether CC can provide safety and healing, or if it is harmful and retraumatizing to children. In recent years CC has come under scrutiny due to high per diem costs and increasing reports of abuse and even death of children. In response, the federal Families First Prevention Services Act (FFPSA) was enacted in 2018 with a goal of reducing the number of children in CC. Since then, efforts have been implemented nationwide to achieve this goal. This study explored the value of statewide trauma screening …

Evaluation Of A Brief Act Intervention For Reducing Depression And Anxiety Symptoms In Sexual And Gender Minority Adults, Allie Mann

Dissertations

Sexual and gender minority individuals (SGM) are at increased risk for psychological disorders compared to the general population. Despite this well-documented disparity in mental health outcomes, there is a stark lack of treatment studies examining SGM mental health. An accumulation of research has demonstrated that the source of this disparity is increased exposure of SGM individuals to stigma-related minority stress. It is necessary to examine psychological pathways that are impacted by stigma and the treatments that can reduce psychological distress in this population. Currently, we do not have the research evidence to answer the questions of if current evidence-based treatments …

Exploring The Dimensions Of Lesbian, Gay, And Bisexual Affirmative Clinical Supervision, Lindsey N. Dollar

Dissertations

Graduate programs have continued to improve over time regarding incorporating training on LGB issues into coursework and practicum experiences with less emphasis on supervision. Since supervision is a major training area where therapists learn about clients and themselves, it becomes an important area for also teaching supervisees how to work with minority populations. However, relatively absent from discussions of cultural influences in supervision is a focus on LGB concerns, and missing is the ‘how to’ within the supervisory relationship. This quantitative investigation sought to learn how clinical supervisors with knowledge of LGB issues and people implement LGB-affirmative supervision, and to …
