An Acoustic Phonetic Analysis Of African American English: A Comparative Study Of Two Dialects, Catherine A. Adams

Master's Theses and Doctoral Dissertations

In this thesis, I contribute acoustic phonetic data and analysis to the study of African American English (AAE). For this research, I collected speech samples of self-identified AAE speakers and speakers of a dominant coexisting dialect, the Northern Cities Shift (NCS). I analyze these samples to determine if vowel quality and vowel duration are consistently and predictably varied between the two dialects. Labov's Chain Shift Principles are used as the context for the results.

In my analysis, I find that both vowel quality and duration are different between AAE and NCS in ways previously undocumented in the linguistic literature. The …

A Model To Study Cyber Attack Mechanics And Denial-Of-Service Exploits Over The Internet's Router Infrastructure Using Colored Petri Nets, Lawrence M. Healy

Master's Theses and Doctoral Dissertations

The Internet‟s router infrastructure, a scale-free computer network, is vulnerable to targeted denial-of-service (DoS) attacks. Protecting this infrastructure‟s stability is a vital national interest because of the dependence of economic and national security transactions on the Internet. Current defensive countermeasures that rely on monitoring specific router traffic have been shown to be costly, inefficient, impractical, and reactive rather than anticipatory.

To address these issues, this research investigation considers a new paradigm that relies on the systemic changes that occur during a cyber attack, rather than individual router traffic anomalies. It has been hypothesized in the literature that systemic knowledge of …

The Impact Of Pre-Treatment Identification Of Personality Style And Personality Disorder Symptoms On Psychotherapy Outcomes In A Training Clinic, Shauncie Marie Skidmore

The Reliability And Validity Of An Admissions Tool In Predicting Academic And Fieldwork Achievement In Occupational Therapy Students, Jeanine Biese

Master's Theses and Doctoral Dissertations

In an uncertain economy, many students of higher education are drawn to the security of careers in health care, such as Occupational Therapy (OT). It is important that as admissions committees evaluate an increasing applicant pool they select students who will be successful in the programs and therefore maximize the number of graduates into the professions. Some health care admissions programs look only at the applicant’s grade point average (GPA) and/or results of standardized tests such as the Graduate Records Exam (GRE). There is a gap in the literature in regard to how to select students who have traits linked …

Experiential Retailing: Extraordinary Store Environments And Purchase Behavior, Alana Nicole Garvin

Master's Theses and Doctoral Dissertations

The purpose of this study was to determine how store atmospherics affect purchase behavior in experiential stores. It extended the Donovan et al. study, “Store Atmosphere and Purchasing Behavior” (1994), by determining the levels of pleasure and arousal in an experiential store and the affects on unplanned spending and unplanned time spent in the store. This was done by measuring customers’ emotions five minutes into the shopping experience and comparing planned amount of time and money spent to the actual amounts. The findings of this study showed that higher levels of pleasure and arousal did not affect unplanned time and …

Predictors Of Help-Seeking In Returning Operation Enduring Freedom (Oef) And Operation Iraqi Freedom (Oif) Veterans, Carole Porcari

Master's Theses and Doctoral Dissertations

Despite a significant number of Afghanistan and Iraqi veterans who reported symptoms of PTSD, depression, anxiety, and substance abuse, the majority of these veterans did not seek help for these problems. Past research has shown several variables that may contribute to an individual seeking help for a mental health problem including demographic variables, nature and severity of the mental health problem, and psychological variables. All Operation Enduring Freedom (OEF) and Operation Iraqi Freedom (OIF) veterans and service members that registered with the Ann Arbor VA Healthcare System between 2001 and 2007 were contacted by mail and asked to participate in …

Intentions To Seek Therapy, Attitudes, And Stigma: An Analysis Of The Theory Of Reasoned Action, Matthew J. Altiere

Master's Theses and Doctoral Dissertations

The relatively low utilization of mental health care is a concern for psychology, as only 32% of individuals with a psychological disorder receive treatment (Andrews, Issakidis, & Carter, 2001). It is typically attitudinal rather than structural barriers that influence individuals when deciding to pursue treatment (Outram, Murphy, & Cockburn, 2004). This study utilized the theory of reasoned action as a model to test the relationship among variables hypothesized to contribute to the intention to seek therapy: public stigma, self-stigma, social support, self-efficacy, attitudes toward seeking therapy, and psychological distress. Both quantitative and qualitative methods were used to evaluate barriers to …

Assimilative Demands: The Psychological Impact Of Legal Decisions On Lesbians’ Lives, Melissa J. Grey

Master's Theses and Doctoral Dissertations

Covering, a construct that has been absent from the empirical psychological literature, is the pressure to or act of downplaying characteristics associated with a stigmatized identity (Goffman, 1963). This research investigated the covering demand in lesbian-identified women drawing on four related literatures: acculturation, discrimination, stigma, and self-concealment. The objectives of this research were to examine the impact of structural, legal covering demands on psychological domains and develop a grounded understanding of these demands in lesbian women. A mixed-method approach was utilized. Forty-six lesbian-identified women recruited from community venues participated in the quasi-experiment and focus groups, and five also engaged in …

Exposure To A Computer-Hosted Cognitive-Behavioral Intervention For Pathological Gambling: Impact On Gambling Symptomatology And Disclosure Of Gambling Participation In Required Counseling For Adults Receiving Opiate Substitution Therapy For Heroin Addiction, Andrew E. Cameron

Master's Theses and Doctoral Dissertations

This study examined the prevalence of pathological gambling (PG) in an urban methadone-maintenance population (n=125) using the South Oaks Gambling Screen (SOGS). In addition, those meeting criteria for PG, and other inclusion criteria (n=42), were randomly assigned to one of two 6-week treatment groups and given the opportunity to utilize a computer-hosted cognitive-behavioral treatment program for PG. Seventeen participants used the treatment program, but no effect was found on their gambling behavior as measured by the SOGS and Timeline Follow-back procedure. Predictive factors of PG severity and treatment response were examined. Overall, 47.1% of those sampled …

Water Intake And Adherence To Clear Fluid Goals In Children Receiving Treatment For Encopresis, Elizabeth Shannon Kuhl

Master's Theses and Doctoral Dissertations

A six-session group intervention for treatment of retentive encopresis designed by Stark and colleagues yields high adherence for fiber (Stark et al., 1990a; Stark et al., 1997), but not fluid (Kuhl et al., 2009), recommendations. Children may also rely heavily on drinking juice to meet their clear fluid targets (Kuhl et al., 2009). This study examined the effectiveness of an enhanced intervention (EI) in improving children’s fluid goal adherence and modifying their daily fluid intake to include more water and less juice.

Data for 19 children who completed treatment previously served as the Non-Enhanced Intervention (NEI), and 18 children completed …

Acceptability Of Parent-Child Interaction Therapy, Jacqueline Mezza Titus

Master's Theses and Doctoral Dissertations

The behaviors associated with Oppositional Defiant Disorder and other disruptive behavior disorders constitute the most common reason for referral of young children to mental health services (Schuhmann, Durning, Eyberg, & Boggs, 1996). Parent-Child Interaction Therapy is an empirically supported treatment for such disorders. However, families are frequently unable to maximize their use of such treatments. Barriers to treatment participation prevent families from entering or staying in treatment. While most of the treatment effectiveness research has been conducted with Caucasian families, African American families and Caucasian families experience these barriers to different degrees, resulting in varying treatment adherence and unclear treatment …

Qualitative Study Of Trauma Outcomes Among Acehnese Tsunami Survivors, Amrit Kaur

Master's Theses and Doctoral Dissertations

This study uses qualitative methods to understand trauma from an indigenous perspective and to assess the validity of the DSM-IV (APA, 2000) diagnosis PTSD and depression in a remote Asian population. Twelve individuals were interviewed about their post-tsunami difficulties in the Indonesian province of Aceh. Contrary to our expectations, participants reported significant numbers of almost all DSM-IV-TR symptoms of PTSD and depression. Although the expressions of illness symptoms were colored by the local language and customs, participants reported few symptoms that could be seen as unique to this culture. These finding suggest that Western developed DSM-IV-TR symptomatology may be largely …

Factors Related To Formal And Informal Help-Seeking For Perinatal Depressive Symptoms, Erin Henshaw

Master's Theses and Doctoral Dissertations

Effective treatment for maternal depression improves overall maternal functioning and prevents the negative infant outcomes associated with maternal depression (Verduyn et al., 2003). Despite the clear benefits associated with treatment for perinatal depression, less than one third of depressed women seek any form of treatment (Flynn et al, 2006). The Health Belief Model (HBM) has received some support for other health-promoting behaviors, but its relevance for explaining mental health help-seeking has not been adequately tested. This study adds to the literature by simultaneously providing a more comprehensive and adequate test of the HBM in predicting mental health treatment for depression …

Characterization Of Pet Samples Processed In An Rf Oxygen Discharge, Russell L. Rhoton

Master's Theses and Doctoral Dissertations

A radio frequency plasma (13.56 MHz) was used to modify the surface of a poly (ethylene terepthalate) (PET) sample. The plasma was generated in a pure oxygen process atmosphere at pressures of 100 mTorr, and 2.0 Torr at output powers of 250 Watts and 500 Watts.

Optical emission spectroscopy (OES) was used to characterize the plasma/sample interaction. Spectra were measured from 250 nm to 900 nm during each of the processing sessions.

The spectra showed changes depending upon the pressure of the plasma. Molecules of OH and atomic oxygen were observed at low pressures (100 mTorr), whereas CO and atomic …

African American Women Superintendents: Their Point Of Exit, Minta Maxine Downing

Master's Theses and Doctoral Dissertations

Only recently have scholars paid attention to the African American woman superintendent who is an anomaly in this powerful leadership position in public education. Additionally, only a few academicians have asked why talented African American women who successfully obtain the superintendency exit the position so quickly. The primary purpose of this phenomenological focused qualitative study was to identify and document the experiences contributing to the decisions of selected former African American women superintendents to exit, voluntarily or involuntarily, their public school superintendencies and not to seek another one, choosing instead to pursue other positions, either in education or in a …

Materials And Coatings Derived From The Polymerizable Ionic Liquid Surfactants 1-(2-Acryloyloxyundecyl)-3-Methylimidazolium Tetrafluoroborate And 1-(2-Acryloyloxyundecyl)-3-Methylimidazolium 2-Acrylamido-2-Methyl-Propylsulfonate, Hong Gu

Master's Theses and Doctoral Dissertations

Polymerizable ionic liquid surfactants were synthesized and polymerized, yielding engineered advanced polymers that can be tailored for diverse applications. First, 1-(2-acryloyloxyundecyl)-3-methylimidazolium tetrafluoroborate (IL-BF₄) was synthesized and was copolymerized with methyl methacrylate (MMA) via microemulsion polymerization. The resulting polymer gels can be transformed into porous materials by anion exchange, and the porosity of the material can be tuned through the solvent shifting. Second, an ionic liquid composed of a 1-(2-acryloyloxyundecyl)-3- methylimidazolium (IL) cation and 2-acryloamido-2-methyl-propylsulfonate (AMPS) anion was synthesized and polymerized by UV irradiation, and introductory data are illustrated for humidity sensitive preparations suitable for chemFETs, for proton conducting …

A Quasi-Experimental Study On Students' Perceptions And Intended Use Of Digital Recording Technology In A College Technology Classroom, Zenia Bahorski

Master's Theses and Doctoral Dissertations

This quasi-experimental study employed a modified Technology Acceptance Model approach in conjunction with a Perceived Classroom Interaction Model. The study investigated the impact of digital audio recording of college classroom lectures on students' perceptions of interaction levels, usefulness, and use of the digital media.

The study surveyed six introductory computer science and technology classes. Previous computer knowledge was not assumed. The results found no significant differences of students' perceptions of interaction levels in traditional classroom lectures. However, gender was found to have a significant effect on speaking in class when a recorder was present. No significant differences were found when …

Crib Dock Permit And Construction Standards In The Upper Great Lakes, Brian J. Hoxie

Master's Theses and Doctoral Dissertations

This study explored the permitting, design, and construction of crib docks in the Les Cheneaux and Drummond Island region of Michigan. It employed an exploratory two-phase mixed-methods research design: first to qualitatively explore and define the problem, and then to quantitatively evaluate a convenience sample of crib docks to determine appropriate permit and construction norms that meet functional requirements while addressing ecological and waterway concerns. The variables considered included siting, design, superstructure, and ground anchorage.

The qualitative findings demonstrated that the USACE and MDEQ are the approving agencies for crib docks and oppose new crib dock construction permits, because they …

Thermoregulation And Behavior Of A Peripheral Population Of Evening Bats (Nycticeius Humeralis), Rachel Bricklin

Master's Theses and Doctoral Dissertations

I used temperature-sensitive radio transmitters to measure body temperatures of tree-roosting evening bats (Nycticeius humeralis) at the northern edge of their range in Lenawee Co., Michigan. Temperature at sunset, diurnal temperature, and nocturnal temperature significantly correlated with use of torpor, whereas ambient temperature at sunset of the previous night, temperature at sunrise, amount of precipitation, abundance of insects, roost type, number of roost-mates, reproductive condition, and age did not. An analysis of individuals roosting in the same tree on the same day suggested that additional factors might determine exactly how low and for how long bats adjust their …

The Influence Of Adult Attachment Styles On Coping With Bereavement, Sarah Wice

Master's Theses and Doctoral Dissertations

This study explored the associations between adult attachment style, coping style, religious beliefs, and experiences with grief. Participants from local bereavement and religious groups completed questionnaires about these constructs.

Hyp. 1-2 predicted that greater endorsement of Secure and Dismissingly Avoidant attachment styles would be associated with less Subjective Distress. Results partially supported these hypotheses. Hyp. 3-6 predicted that the relationship between a Substitute Attachment Figure and adult attachment style would be associated with religious beliefs. Results did not support these hypotheses. Hyp. 7-9 predicted that greater endorsement of Secure and Dismissingly Avoidant attachment styles would be associated with more problem …

The Impact Of Homelessness On Young Children: Building Resilience Through Supportive Early Educational Interventions, Felice Moorman

Master's Theses and Doctoral Dissertations

This qualitative study investigates and analyzes the barriers faced by homeless children and their families in southeast Michigan. The experiences of current or formerly homeless families are documented in relation to perceived obstacles and supports in their schools and child care centers through open-ended, semi-structured interviews and ethnographic classroom observations. A small sample of parents, children, teachers, and case workers are interviewed, and nine children are observed in three schools. The analysis of data reveals significant barriers and obstacles for children who experience indifferent and demeaning treatment in their school environments. Conversely, the findings point to significant benefits for homeless …

Role Of Aromatic Pi-Stacking On The Aggregation Of Human Islet Amyloid Polypeptide (Hiapp), Srikanth Reddy Konda

Master's Theses and Doctoral Dissertations

Human islet amyloid polypeptide (hIAPP) is secreted in the β-cells of the pancreas, which also secretes insulin. In type 2 diabetes mellitus, hIAPP undergoes self-aggregation, forming fibrils. This self-aggregation is cytotoxic and is thought to be linked to type 2 diabetes mellitus by causing β-cell membrane destruction. The N-terminus of hIAPP (1-19) contains a binding site (residues 14-18) for self-aggregation. Aggregation is thought to be mediated by pistacking interactions between phenylalanine residues of hIAPP. In this study, the hIAPP 1-19 sequence was modified by replacing phenylalanine with alanine and naphthylalanine, to study if the modification of the aromatic side chain …

Walk To Jerusalem: Facilitating Physical Activity In A Faith Community, Lisa Schmidt

Master's Theses and Doctoral Dissertations

Obesity and physical inactivity are on the rise in our society today. Combined with poor eating habits, many Americans are overweight or obese. Churches have become important settings for providing health education programs, especially for African-American populations. There have been mixed results from faith-based physical activity studies, and few have been conducted with Caucasian populations. The present study used the Walk to Jerusalem program as a motivational tool within a Caucasian faith-based setting. The objectives were to increase physical activity, decrease blood pressure and weight, if needed, and improve attitude toward physical activity. The primary objective of the project was …

Prevalence Of Vitamin D Insufficiency Among Breast Cancer Survivors, Kristen Poole Trukova

Master's Theses and Doctoral Dissertations

The objective of this study was to determine if vitamin D deficiency is a prevalent problem for female breast cancer survivors (BCS) who have completed treatment for breast cancer. Ninetynine breast cancer survivors and a control population of fifty-five women with no history of breast cancer participated in this study. Serum 25-hydroxy vitamin D concentrations were measured throughout 2007. Dietary and supplement intake of vitamin D was assessed by a food frequency questionnaire. Zip code of residence was used to evaluate potential for skin production of vitamin D. Vitamin D deficiency (<32ng/mL) was observed in 76 of 99 (77%) of BCS, and 51 of 55 (93%) of controls. Women taking vitamin D supplements were less likely to exhibit vitamin D deficiency, but supplementation did not guarantee sufficiency. Vitamin D deficiency appears to be prevalent among both groups. Vitamin D status should be routinely evaluated for all women as part of regular preventive care.

An Improved Synthesis Of The Hdac Inhibitor Trichostatin A, Joseph Colombo

Master's Theses and Doctoral Dissertations

Histone deacetylase inhibitors (HDIs) have found a wide variety of medicinal uses and are most noted for their specific apoptotic action towards cancer cells. Several hydroxamate HDIs have since been moved on to phase 1 and 2 clinical drug trials, with one having already been approved for treatment of advanced cutaneous T-cell lymphoma. Trichostatin A is one of the most potent known naturally-occurring inhibitors of histone deacetylase. Unfortunately for researchers, the syntheses that have been reported are both long and difficult, which leads to a low overall yield and therefore to a prohibitively expensive product, limiting its medicinal potential. This …

The Prophetic Imagination Of P. B. Shelley, Andrew O. Winckles

Master's Theses and Doctoral Dissertations

In his “Defence of Poetry,” Shelley claims, “Poets… were called in the earlier epochs of the world legislators or prophets.” As such, even a cursory glance at Shelley’s poetry and political beliefs reveals an interest in what is wrong with the world, how to fix it, and what will happen if no action is taken. However, current studies fail to fully assess what makes up the prophetic imagination. They confine discussions of Romantic prophecy to discussions of prophetic inspiration, futurity, and rhetoric – divorcing the work from its impetus for social change. The prophetic imagination, as utilized by Shelley, is …

Master's Theses and Doctoral Dissertations

The objective of the present study was to determine serum 25(OH)D and PTH concentrations as well as vitamin D and Ca dietary intake in healthy pregnant (P) (n=48) and non-pregnant (NP) (n=70) Saudi Arabian women who reside in Mecca- Saudi Arabia. Age, occupation, skin color, smoking status, use of sunscreen, use of supplements, and sun exposure were correlated to vitamin D status. Dietary and supplement intake was assessed. Among the participants, 50.8% (35% P, 65% NP) women had 25(OH)D concentration that were ≤ 11 ng/mL. PTH concentrations were normal in 60.2% and high in 37% of the participants. Dietary vitamin …

Language, Emotion, And Imagination: Constructing Human Identity Through Hemingway's Work, Gorka Diaz

Master's Theses and Doctoral Dissertations

This thesis examines how Hemingway’s use of language evokes emotions in his stories and how his particular way of evoking emotions affects readers. Hemingway’s style of providing vivid experiences for readers centers on the image as the dimension where emotions are offered, but also the dimension where the writer’s work converges with the reader’s reception of it. The reader reconstructs the text through the act of signifying emotions. This process of signification is made possible only through the use of the reader’s imagination. The study of the relation between emotion and imagination emphasizes that readers decode fiction as they decode …
