The Effects Of Music Instruction On Phonological Awareness In Children With Hearing Impairment, Chelsea Fitch

Masters Theses

Phonological awareness skills are essential for reading development. Children with hearing loss lack access to essential auditory information that allows development of phonological awareness (Dillon, John, & Pisoni, 2011). Music instruction is becoming a popular approach to teach reading for typically developing children, and studies have supported beneficial effects from this treatment methodology. However, there is limited research regarding the use of music to teach phonological awareness and reading skills to children with hearing impairment (Gromko, 2005).

The effectiveness of a music program on increasing phonological awareness skills in children who are deaf or hard-of-hearing was evaluated in this study. …

Emotional Intelligence, Coping Styles, And Psychopathology, Letizia Boin

Masters Theses

Despite its relatively recent origins, Emotional Intelligence (EI), which is the ability to perceive, understand, and manage one's emotions, has been shown to contribute to a variety of outcomes, including academic achievement and relationship satisfaction. Considerable support has been gathered to implicate EI in the development of mental illness such as depression and social anxiety. It has been theorized that a potential pathway in which EI affects mental health is by contributing to the development of coping styles. Stress and coping literature reports enough empirical evidence to suggest that broadly speaking, problem-focused coping is 'adaptive' while avoidant coping is 'maladaptive.' …

Increasing Cooking And Nutritional Knowledge Of Food Pantry Clients Via Cookbook Intervention, Joshua Kleczynski

Masters Theses

This study was designed to assess eating habits, cooking habits, and nutritional knowledge of food pantry clients. As a whole, the average American consumes a less-than-optimal intake of nutrients. This, combined with the elevated national food insecurity rate of 14.5%, produces an advantageous situation to educate food pantry clients about healthy lifestyle practice through cooking. This study utilized a quasi-experimental design including a pre-assessment, intervention, post-assessment design. Forty-nine participants were included in study, and either received a cookbook (intervention group) or were a control subject and only completed surveys. Results revealed that the cookbook intervention did not elicit any behavior …

Exploratory Factor Analysis Of Body Dysmorphic Disorder Symptom Clusters, Rachel A. Maxwell

Masters Theses

Body dysmorphic disorder (BDD) is a distressing condition that involves a preoccupation with a perceived defect(s) in appearance. Despite the importance of early identification, it is often misdiagnosed. The literature suggests that issues with diagnosis may be because BDD is typically defined by the single symptom of dysmorphic concern (i.e., over concern with an imagined or slight defect in physical appearance). Dysmorphic concern is insufficient to fully characterize the disturbance. This study used exploratory factor analysis to identify symptom clusters from four well-known BDD measures completed by 457 undergraduate students. The extracted content suggested the following symptoms: (a) Dysmorphic Concern, …

The Perceived Benefits Of Participation In Living And Learning Communities: The Student Perspective, Sally Adams

Masters Theses

Students' experiences outside the classroom are important to their overall growth and development. Living learning communities (LLC) play a big role in helping to support these areas of growth. Students residing in an LLC are aware of the benefits of the LLC experience and can articulate how their residential environment can help them develop. Non-LLC members find it difficult to define the LLC experience and are not receiving the same benefits. Institutions and residence life often struggle in evaluating and assessing these communities because of the lack of direction and outcomes not clearly being stated. If institutions work to clearly …

Foreign Direct Investment Led Growth And Its Determinants In Sub-Saharan African Countries, Tewodros Zerihun Demelew

Masters Theses

Despite FDI's growth in Sub-Saharan African (SSA) countries, the evidence from earlier studies on FDI led economic growth and key determinants of FDI in SSA countries have been inconclusive. This paper provides up-to-date evidence on the question: does FDI lead to economic growth? And if so, what are the key determinants of FDI growth in SSA countries? In this study we use three estimation approaches, OLS with robust standard errors (robust regression), multi-level random-effects regression, and fixed-effects regression. The multi-level and fixed-effects regression are aimed to help us control for within-country and between-country effects. Based on a panel dataset for …

The Effects Of Existential Salience On State Anxiety, Joseph Morger

Masters Theses

Existential anxiety is theorized to result from one's knowledge of human existence. Four givens of life have been identified that result in existential anxiety: death, freedom, isolation, and meaninglessness (Yalom, 1980). Terror management theory purposes the knowledge of one's own death to be a great source of distress. The theory posits that to cope with these distressing thoughts, one is motivated to adhere to a cultural worldview. Adhering to a cultural worldview allows one to view the world as a structured place, in addition to raising one's self-esteem. Terror management research has shown that making mortality salient results in harsher …

Effects Of Instream Habitat Restoration On Macroinvertebrate And Fish Communities In A Small Midwestern Stream, Manisha Pant

Masters Theses

Although millions of dollars are spent annually on stream habitat restoration, the biological responses to these restorations are rarely monitored. I assessed the impact of habitat enhancement on fish and macroinvertebrate abundance and diversity in a small Midwestern stream. Fish and macroinvertebrate communities were sampled annually in two restored and two unrestored sites beginning two years before and continuing four years after restoration. Habitat heterogeneity increased in the restored sites following the restoration, but there were no significant changes in most macroinvertebrate and fish community indices. Macroinvertebrate composition was significantly different between spring and fall, but in general, assemblages within …

Does Parent Management Of Past Childhood Sibling Aggression Predict Young Adult Emotion Regulation? A Retrospective Study, Joseph P. Berry

Masters Theses

Childhood sibling aggression and its influence on an individual's ability to regulate emotions later in life have not been extensively studied at this point in time. Prior research indicates that repeatedly being the victim of childhood aggression can lead to concurrent social, psychological, and emotional difficulties (Crick, Bigbee, & Howes, 1996). This study used a retrospective approach to explore whether 139 college students' experiences of overt and relational childhood sibling aggression are related to current difficulties with emotion regulation in young adulthood. Overt sibling aggression or relational sibling aggression in childhood predicted difficulties in current emotion regulation. Beliefs about the …

Exploring The Relationship Between Self-Reported Religiosity And Alcohol Usage Among Undergraduate Students, Angelica Maria Bradley

Masters Theses

Alcohol usage is one of the greatest high-risk behaviors that institutions face today. In this study, 166 undergraduates were surveyed to explore the relationship between their religiosity and alcohol usage. The data revealed that religious students drink less than unsure or spiritual students, supporting the Social Identity Theory, which suggests that a group a student most identifies with influences them the greatest. The study also suggests that we should seek to understand this relationship, which can lead to a better understanding of why students use alcohol, and therefore, a step closer to helping them succeed where it matters most.

Grief, Loss And Stress Burden Among Spouse Caregivers Of The Person With Young-Onset Dementia, Sharbari Ganguly

Masters Theses

The effects of young/early-onset dementia are devastating not only for the person who has been diagnosed with young/early-onset dementia, but also for their primary caregivers (de Vugt & Verhey, 2013). The major aim of this study is to focus on the level of grief, loss, and stress burden that are associated with the partner or the spouse caregivers of someone with young-onset dementia. This study has used a previously unanalyzed set of data consisting of 55 partner or spouse young-onset dementia caregivers. Three instruments were used for data collection including the Marwit-Meuser Caregiver Grief Inventory (MMCGI), the Zarit Burden Interview …

Sexual And Political Affairs: Representation Of Women In American News Media, Melissa Beal

Masters Theses

Explores representations in American news media of women who have been involved sexually with male politicians and women who are politicians through a critical rhetorical lens. Through the use of poststructural feminism, the term "mistress" is problematized. Attention is given to the news media's focus on women's bodies as sites of dangerous sexual temptations as well as the media's constant attention to women's physical features, which reduces women to objects. It is shown that similar coverage regarding bodies is not given to men. Also discusses the news media's frequent interrogation of women's minds. Explores aspects of confession and apology through …

Are Supervisory Feedback Messages A Motivational Factor To Enhance Employee Retention?, Yang Yali

Masters Theses

Employee retention is one of most valuable resources in an organization. Feedback from supervisors provides opportunities to clarify expectations, adjust goal difficulty, improve job performance, and enhance job satisfaction. The present study is intended to investigate the role that supervisory feedback messages play in employee retention decisions. The participants took a three-session survey that aimed to examine their perception of supervisory feedback received through direction-giving messages, empathy-giving messages, and meaning-making messages, as well as the effect that each kind of message had on each participant's retention intent. The follow-up interviews were conducted to explore in-depth insights on the factors motivating …

Still Siblings: The Perceived Importance Of Sibling Relationships For Foster Children, Jessica A. Church

Masters Theses

This research was conducted to answer the question “Do children who are perceived to have strong relationships with siblings and more access to their siblings have fewer problems adjusting to their foster care placement as observed by child welfare professionals?” This qualitative research project was completed through semi-structured interviews with professionals who work with children in foster care in a variety of ways (and may have worked with children in more than one way during their career in child welfare), such as foster care workers, counselors, and sibling visitation supervisors. The snowball sampling method was used in this research. These …

Evaluation Of The Efficacy Of A Rat Agreement Based Reinforcement Procedure, Katherine B. Lalonde

Masters Theses

Since 2007, giant African pouched rats (Cricetomys gambianus) have been used successfullyfor detecting Tuberculosis (TB) positive patients.The rats are trained to detect TB-positive sputum samples through the use of operant conditioning techniques, in which an indicator response is rewarded with food. If the rats are to be used for first line screening of patients reinforcement could not be provided because the true status of the sample would be unknown. The present study evaluated the effects of a reinforcement-for-agreement procedure that could be used to reinforce indication responses when the true status of the sample is unknown. Four rats evaluated 100 …

La Oficina De La Mujer (Omm): A Conduit For Social Empowerment Among Women In A Small Guatemalan Lake Community, Rachel Volk

Masters Theses

La Oficina de Municipal de la Mujer, the Municipal Office of Women, is a recent creation of the Guatemalan central government meant to help address the inequalities that women experience each day. Like so many towns in Guatemala, La Laguna (pseudonym) contains high levels of poverty and unemployment. Here, women encounter difficulties finding employment, whether as a result of the poor economy or the bigotry arising from structural sexism and racism. My investigation of the OMM uses qualitative anthropological techniques to understand the purpose and effects that this organization has towards women‟s marginalized position in the town. The application of …

Inkjet Printing Of Titanium Dioxide Photoanodes For Dye Sensitized Solar Cells, Jeffrey Corbet Johnson

Masters Theses

Dye Sensitized Solar Cells (DSSC) offer advantages over semiconductor solar cells including lower costs and relaxed material purity requirements. However, DSSC solar energy conversion efficiencies are lower than many competing photovoltaic technologies. Key to DSSC performance is the incorporation of nanocrystalline metal oxides to provide a large surface area for photosensitive dye loading. Titanium dioxide (TiO2) is the predominately used metal oxide. The structure of the TiO₂ layer determines charge transfer efficiency and the level of generated photocurrent. Common practice for high performance cells is to deposit a thin, compact TiO₂ coating followed by a thicker, more porous …

Effects Of Nonylphenol On Orientation By The Crayfish Orconectes Propinquus, Kathryn J. Page

Masters Theses

Nonylphenol is a widely used surfactant subject to ethoxylation and subsists in the environment for significant amounts of time. It has industrial, agricultural, and domestic uses, and makes its way into the aquatic ecosystem despite treatment of wastewater. Detrimental effects of nonylphenol are varied, but most notably endocrine disruption has been examined. Crayfish are a crucial invertebrate in freshwater ecosystems. They are omnivorous, and occupy a key position in the trophic web as both predator and prey. To determine if nonylphenol exposure has any effect on the orientation abilities of crayfish, I acutely (1 day) and chronically (4 days) exposed …

Changes In Vascular Reactivity Of Mesenteric Arteries Following Hyperbaric Oxygen Treatment, Benjamin Matthew Hake

Masters Theses

The objective of this study was to evaluate the changes in vascular reactivity of mesenteric arteries resulting from hyperbaric oxygen treatment. It was hypothesized that hyperbaric oxygen treatment alters vascular reactivity in mesenteric arteries due to enhanced production of ATP resulting in significantly larger responses to vasoactive stimuli. All arteries were dissected from porcine mesenteries and placed in Krebs- Henseleit solution. Arteries were initially mounted in isolated organ baths and passively loaded with tensions ranging from 1 to 25 grams at odd intervals to ascertain the optimal passive tension for studying mesenteric arteries. Following a 1-hour equilibration in Krebs-Henseleit solution, …

Climate Change And Metapopulation Implications For Species Re/Introductions: A Spatial Analysis Of Suitable Habitat For The American Marten (Martes Americana) In Northern Michigan, Joshua Michael Green

Masters Theses

The American marten (Martes americana), which was extirpated from Michigan by 1939 due to logging and trapping, has cultural significance as a clan animal to Great Lakes Native American Tribes and ecological significance as a forest health indicator. Sleeping Bear Dunes National Lakeshore (SBD) is considering reintroduction, but several factors must first be considered in assessing the habitat suitability. The goals of this study were to 1) enhance an existing habitat suitability model by including additional relevant variables, 2) conduct a spatial analysis of the habitat within the study area using a metapopulation perspective and 3) incorporate climate …

Labeling Research Deviant: A Comparative Analysis Of Federal Ad Hoc Commissions On Human Subject Research, Brian W. Rossana

Masters Theses

A review of the literature suggests there is still reason for concern due to the nature of deviant research in the past and the continued existence of ambiguous guidelines in particular organizational contexts. Federal ad hoc commissions have been a prominent environment where the absorption of the social reaction to deviant events and discussions regarding bioethics has transpired. The goal then was to ask what conditions of commissions lead to the presence of a research deviant? A convenience sample of nine U.S. federal ad hoc commissions was performed utilizing a method known as crisp-set Qualitative Comparative Analysis (csQCA). The results …

Refugee Reflections: A Focus On The Lived Experiences Of African Refugees Resettling In Michigan, Diane Roushangar

Masters Theses

Refugee resettlement is often observed by focusing on external indicators of integration such as employment and English proficiency. What is often ignored is the multi-faceted process refugees experience in regard to the emotions that occur during these transitions of resettlement. Emotional stressors include financial concerns, work-related issues, a lack of adequate counseling services and ESL support that can all lead to increased anxiety. This paper examines the process of resettlement that northeast African and sub-Saharan African refugees have experienced including issues of unsafe working conditions, changing gender roles, and a lack of adequate time for adjusting to the culture.

Origin Of High Levels Of Ammonium In Groundwater, Ottawa County, Michigan, Derrick Lingle

Masters Theses

Groundwater from wells located in and around Hemlock Crossing Park in Ottawa County, Michigan has elevated levels of ammonium. High ammonium concentrations in potable water wells are a common indicator of anthropogenic impact, such as landfill leachate or agricultural activity. Ammonium can also occur in groundwater through the decay of natural organic material. Along with the retrieval of a complete glacial sediment core via rotasonic drilling, numerous chemical and isotopic parameters were used to determine the source of ammonium in the impacted aquifer.

Buried organic material, deposited during the Athens subepisode interglacial period, is in contact with groundwater containing elevated …

Disease Ecology Of A Microsporidian Parasite And Its Effects On Mottled Sculpin, Jared Joseph Homola

Masters Theses

Infectious disease can influence organisms at all levels of ecological organization, from individuals to ecosystems. Likewise, the ecosystems where pathogens exist directly influence their success. Recent theoretical studies have tied disease prevalence to biotic factors such as genetic diversity, biodiversity, and host behavior, and abiotic factors that include temperature and increased nutrient concentrations. Parasites included in the phylum Microspora are increasingly recognized for being ubiquitous in nature, although their ecological roles are generally unknown. This study examined several environmental, community, and host-related metrics to compare the biotic and abiotic aspects of 16 small streams; 6 with mottled sculpin (Cottus …

Predicting The Effects Of Land-Use And Climate Change On Michigan Stream Ecosystems, Jacqueline M. Taylor

Neiman Marcus Chicken Coops: Exploring Class And Identity Through Backyard Chicken Keeping And The Contemporary Food Movement, Traci D. Joseph

Masters Theses

This paper is a case study of a proposed backyard chicken ordinance for Grand Rapids, Michigan. The study is viewed in light of social movement theory, specifically new social movement theory, to determine if events surrounding and leading up to the debate can be labeled as a social movement. A key finding is a culture of consumption as a common thread throughout the debate. The poultry industry pushed for continued consumption of its products with an agenda of fear regarding disease and improper handling. Proponents countered with a discussion on an ethic of care for the birds. Ultimately, this rejection …
