Treatment Of Foundational Reading Skills Through Telepractice And Face-To-Face Environments: Single Subject Design, Mary Beth Hetherton

Open Access Dissertations

Service delivery and the access to specialized instructions to consumers, encounters many barriers within the profession of speech-language pathology. This state of affairs is largely due to the disparate distribution of speech language services (ASHA, 2005). This restricted access, or an inability to access services, is a result of a number of factors, which include lack of clinicians, insufficient number of facilities in geographic area, and transportation issues (ASHA, 2004e). As a result, students who require specialized reading instruction are not afforded the opportunity to access the necessary treatment. It is essential that the literacy needs of all children be …

Modeling The Influence Of Childhood Trauma On Rate Of Symptom Change Among Psychiatric Inpatients, Alessandro T. Piselli

Open Access Dissertations

Clinical wisdom suggests that adults with histories of childhood trauma will have difficulty engaging in psychotherapy. I examined the relationship between early childhood trauma and treatment response in the form of rate of symptom decline among a group of 202 adults recruited into the longitudinal Austen Riggs Center Follow-Along Study. Participants were recruited at admission to the hospital and provided extensive demographic and clinical data at baseline, including retrospective recall of childhood traumatic experiences using the Traumatic Antecedents Interview (TAI) and narrative responses to the Relationship Anecdote Paradigm (RAP) used to generate ratings on the Social Cognition and Object Relations …

Evaluation Of Motor Speech And Intervention Planning For Children With Autism, Marcil J. Boucher

Open Access Dissertations

Autism affects 1 in 88 children (Center for Disease Control, 2009), approximately 50% of whom will not develop speech (Seal & Bonvillian, 1997). Some researchers hypothesize that these difficulties in developing oral speech reflect underlying motor speech deficits (Prizant, 1996; Seal & Bonvillian, 1997; Szypulski, 2003; Andrianopoulos, Boucher, Velleman & colleagues 2007-2010). This investigation sought to identify the presence or absence of specific motor speech markers in ASD through an innovative best-practice protocol for assessing the speech, prosody, and voice quality of individuals with ASD.

The study focused on apraxic-like motor planning/programming features and dysarthric-like motor execution features in imitated, …

Effects Of A Classroom-Based Pre-Literacy Intervention For Preschoolers With Communication Disorders, Alyssa Rose Currier

Open Access Dissertations

Children with communication disorders are often at risk of literacy difficulties, especially students that present with autism and/or speech sound disorders. This quasi-experimental study was designed to examine the effects of a 10-week "hybrid" intervention for preschool students with and without communication disorders in an integrated classroom. The classroom intervention targets both vocabulary and phonological awareness, two critical components of literacy that are strongly correlated with one another. The objectives of this study were (1) to provide empirical evidence that classroom-based pre-literacy intervention can be effective for students with communication disabilities, allowing for more time with their peers in a …

An Investigation Of The Efficacy Of Direct And Indirect Aac Service Provision Via Telepractice, Nerissa Hall

Open Access Dissertations

There is a growing population of individuals using Augmentative and Alternative Communication (AAC) in need of evidence-based intervention from highly qualified personnel. However, not all speech pathology programs offer AAC coursework and/or practicum opportunities, and practicing speech-language pathologists (SLPs) report low levels of confidence and expertise in working with individuals using AAC. Therefore, there is a need to develop more innovative pre-professional training programs to better equip the next generation of SLPs with the knowledge and skills necessary to provide high-quality, evidence-based AAC interventions. Telepractice is emerging as an inventive way to provide both direct and indirect intervention services, and …

Theory Of Mind And The Ability To Make Emotional Inferences Among Children With High-Functioning Autism Spectrum Disorders, Abigail Leibovitch

Open Access Dissertations

Perspective-taking skills are central to the successful navigation of social situations. Children need perspective-taking skills to help them correctly interpret different cues and accurately assess social situations so they can determine how to best respond. Children with Autism Spectrum Disorders (ASD) exhibit marked impairments in this area. In order to develop successful social skills interventions for this population, it is critical that we have a strong understanding of the nature of their deficits. While there is robust evidence that children with ASD experience difficulty making inferences about the beliefs of others, research on their ability to infer emotions has had …

Locating The Source Of Approach/Avoidance Effects On Natural Language Category Decisions, Matthew Zivot

Open Access Dissertations

In this dissertation, two exemplar-based models of categorization, the General Context Model (GCM) and the Exemplar Based Random Walk model (EBRW), were used to describe between-group categorization differences in artificial and natural language categories. Prior research has shown that political Conservatives in avoidance mode are more exclusive categorizers of natural language category members than Conservatives in approach mode, but this effect was absent for Liberals (Rock & Janoff-Bulman, 2010). In Experiment 1, experimenter-generated stimuli were used to show that the EBRW could account for between-group differences in categorization decisions. In Experiment 2, the data collected by Rock and Janoff-Bulman were …

Gradients And Ranges Of Visually Selective Attention Based On Location, Objects, Color, And Size: Gradients Are Universal, But Range Is Uniquely Spatial, William S. Bush

Open Access Dissertations

Two interesting properties of the distribution of spatially selective attention have been noted in the behavioral and electrophysiological literature. First, there is a graded field of attention that expands from the center of the attended area. Second, the size of the attended area can be adjusted to be either larger or smaller in order to match the demands of the current task. Five event-related potential (ERP) studies are presented that extend these findings in several important ways; 1) The time frame of these two distribution properties is different. Results are consistent with a two stage model of spatial attention in …

An Investigation Of The Efficacy Of Speech And Language Interventions With Students With Asd Using Telepractice, Michelle Kathleen Boisvert

Open Access Dissertations

There is a national shortage of school-based Speech Language Pathologists (SLP). Schools located in rural and geographically remote areas are often impacted by the shortage, and as a result students with an autism spectrum disorder may not receive services that are mandated by their Individual Education Plan. This study examined the use of telepractice as a method of delivery of speech and language services to individuals with autism spectrum disorders in rural areas. A quasi-experimental, single-subject, time-series design was employed. The treatment conditions were manipulated. A counter-balancing methodology was used to control for order effects in this study. Inter-observer agreement …

The Theory Of Compromised Eating Behavior, Ellen Frances Furman

Open Access Dissertations

The purpose of this inquiry was to develop substantive theory that describes the social process that influences the eating behavior of hospitalized older adults. Undernutrition or the inadequate intake of dietary nutrients necessary to maintain health, contributes to negative health outcomes such as increased morbidity and mortality in hospitalized older adults. Inadequate dietary intake is a risk factor for undernutrition. Despite the availability of vast resources within the hospital environment, hospitalized older adults have inadequate dietary intake. Undernutrition has been studied from a dietary intake perspective; however, why dietary intake remains inadequate is unknown. Inquiry of eating behavior and the …

Expository And Narrative Discourse In Adolescents With Reading And Language Impairments: Assessment And Intervention, Beverly Iuliano

Open Access Dissertations

The purpose of this current study was to first examine through assessments and the use of school-based disability criteria, the quantitative and qualitative patterns in phonological processing, phonological working memory, oral retellings, and oral and written narratives in middle school-aged children with reading disabilities (RD; N=10) and those with language impairments (LI; N=5) in order to provide data to further explain the complex profiles of these two clinical populations. Secondly, a single-subject multiple baseline across subjects design study examined the effectiveness of an intervention program targeting expository and narrative discourse in adolescents with language and reading deficits (N=4). Expository and …

Micronutrient Intake And Premenstrual Syndrome, Patricia O. Chocano-Bedoya

Open Access Dissertations

Premenstrual syndrome (PMS) is characterized by the presence of physical and psychological symptoms restricted to the late luteal phase of the menstrual cycle and associated with substantial impairment in life activities. In the U.S. about 8 to 15% of women of reproductive age suffer from PMS. Many micronutrients are potentially involved in the development of this disorder due to their role in the synthesis of neurotransmitters and hormones or in their regulation, but few previous studies have evaluated the effects of micronutrients on PMS. The first study examined the association between B vitamin intakes, and PMS development among women participating …

Puerto Rican Teens' Perceptions Of Teen Pregnancy And Births In Holyoke, Massachusetts, Nancy J. Gilbert

Open Access Dissertations

The high teen birth rate in Holyoke, Massachusetts is a complex problem. The teen birth rate is over five times the state‘s rate and nearly three times the national rate. Since a majority of these births are to Latinas of Puerto Rican descent it is important to include the perceptions of Puerto Rican teens in approaches to prevent teen pregnancy and reduce the birth rate. Although there is a plethora of research on the topic of teen pregnancy and births, there is scarcity in the area of perceptions held by teens of Puerto Rican descent about teen pregnancy and births, …

Living With A Depressed Partner, Bridget Logan

Open Access Dissertations

Individuals who live with depressed partners have increased rates of anxiety, depression, and difficult coping. They experience greater burdens of parenting and financial responsibilities, and often feel isolated and restricted. Much of this is similar to what has been termed caregiver burden in the context of other illnesses. This study used qualitative interviews to explore the day-to-day experience of what it is like to live with a depressed partner, as well as to test the fit of the term `caregiver burden' in the context of depression. Participants were seven individuals who were in long-term relationships with depressed partners. Analysis of …

Transition To Fatherhood: A Puerto Rican Perspective, Suzanne Barenski

Open Access Dissertations

The purpose of this study was to explore the events that have promoted or hindered a first-time Puerto Rican father's transition to fatherhood. Interviews were conducted with twelve fathers who reported one child one year of age or less. Within the United States the Hispanic population is the largest and the fasting growing minority population. Early father involvement for immigrant and ethnically diverse families has not been widely studied. Analysis of the interview data revealed two main themes; "Accepting of Fatherhood" and "Adjusting to Fatherhood." Specific to these themes, three categories became apparent; "Buying-In: Initial Step to Fatherhood," "The Journey: …

What Women Want To Know: Assessing The Value, Relevance, And Efficacy Of A Self-Management Intervention For Rural Women With Coronary Heart Disease, Holly Evans Madison

Open Access Dissertations

Background: Women have experienced increased mortality from coronary heart disease over the last two decades, while men‘s rate has declined. This suggests that current treatment and prevention strategies are less effective for women. Furthermore, since most women don‘t participate in cardiac rehabilitation, alternatives to these programs must be explored. Purpose: This study sought to refine an intervention for rural women with coronary heart disease designed to promote self-management and provide pilot data evaluating the efficacy of the intervention. Design and Methods: The study design was mixed methods. Focused qualitative interviews provided data regarding the self-management program. In-depth interviews determined the …

The Lived Experience Of College Sudents Who Have Been Medicated With Antidepressants, Pamela Joan Aselton

Open Access Dissertations

Increasingly in the last two decades college students have been diagnosed with depression, with estimates of major depression higher than the general population (American Psychiatric Association {APA}, 2005). According to the literature, the stresses of college life along with increased rates of substance abuse, and binge drinking have contributed to the rise in depression in this population. In a large survey of American college students, over half reported some depression since entering college (National Center on Addiction and Substance Abuse {NCASA}, 2003). Correspondingly, the percentage of young people treated with antidepressants has grown over the past decade, and there is …

What Toxicologists And Risk Assessors Think About Hormesis: Results Of A Knowledge And Opinion Survey, Amy C. Jones

Open Access Dissertations

Hormesis is a nonlinear dose-response characterized by biological responses at low doses that are opposite to those observed at higher doses. Studies and review articles on hormesis are being published at an increasing rate by researchers from diverse disciplines and debate has emerged over the role hormesis in risk assessment. As a result, a survey was conducted to assess toxicologists and risk assessors knowledge and attitudes about the hormesis dose response. Study goals were to: 1) ascertain attitudes towards hormesis and other dose-response models, 2) identify whether acceptance or rejection of hormesis is based on knowledge of hormesis, predisposing values, …

Familiar Physical Activity To Familiar Music: The Effects On Apathy, Agitation, Eating Ability, And Dietary Intake In Institutionalized Older Adults With Dementia, Janet Ruth Moore

Open Access Dissertations

Background: Many older adults with dementia residing in nursing homes or assisted living facilities exhibit behavioral disturbances such as agitation and apathy. In addition they lose their ability to feed themselves and often suffer serious malnutrition as their dietary intake decreases. Music has been linked to decreased agitation in this population and physical activity to music linked to a slower decline in eating ability. Purpose: The purpose of this study was to examine whether a familiar physical activity to familiar music would reduce apathy and agitation and increase eating ability and dietary intake among institutionalized older adults with dementia. Method: …

Vasopressin Anatomy Of The Mouse Brain, Benjamin D. Rood

Open Access Dissertations

The nine amino acid peptide vasopressin acts as a neurohormone in the periphery and a neurotransmitter/neuromodulator in the central nervous system. Historically, research on vasopressin neurons and their projections to the pituitary has helped lay the groundwork for our understanding of peptidergic neurotransmission. Currently, our research on central vasopressin projections is driving a revolution in our understanding of social behavior. Vasopressin affects a number of social behaviors from social memory to aggression to affiliative behavior, such as pair-bonding. Further, with the addition of more and more transgenic mouse models of disease states, anxiety and depression related disorders, and social behavior …

Effects Of Sex And Social Status On Neuromuscular Differentiation In The Eusocial Naked Mole-Rat (Heterocephalus Glaber), Marianne Louise Seney

Open Access Dissertations

Naked mole-rats live in large colonies and exhibit a strict reproductive hierarchy. Each colony has 1 breeding female and 1-3 breeding males; all other individuals are non-reproductive subordinates. Subordinates show a remarkable lack of sex differences in behavior and anatomy, but can become reproductive if removed from the colony. The striated perineal muscles and their innervating motoneurons, which are sexually dimorphic in all other mammals examined, are not dimorphic in subordinate naked mole-rats. Here I asked whether sexual differentiation of this neuromuscular system occurs when subordinates become breeders. Sex differences in perineal motoneurons were not observed, regardless of social status. …

Molecular Changes Following Skeletal Muscle Disuse In Humans, Kimberly A. Reich

Open Access Dissertations

The purpose of this dissertation was to investigate the molecular events associated with the onset of skeletal muscle disuse in humans. Study I examined global gene expression changes in vastus lateralis muscle following 48h unloading (UL) and 24h reloading (RL) in humans. Results showed that functions related to protein degradation and oxidative stress were enriched following UL and that these global gene expression patterns were not readily reversed following RL, thus indicating that molecular events associated with short-term disuse may persist beyond the duration of the stimulus. In contrast to previous work in IM, collagen gene expression increased in this …

Feasibility Of Family Participation In A Delirium Prevention Program For The Older Hospitalized Adult, Deborah Rosenbloom-Brunton

Open Access Dissertations

Objective . To examine the feasibility of family participation in a nurse-supported, multicomponent intervention program for delirium prevention in the older hospitalized adult. Background . Delirium is the leading complication of hospitalization for older adults and is associated with important consequences including increased morbidity and mortality, increased use of health care resources, and increased caregiver burden. The potential role that family caregivers could play in delirium prevention and how nurses could facilitate family participation has been largely unexplored. The Calgary Family Intervention Model (CFIM), operating on the assumptions of a family-centered care philosophy, provided a framework for understanding the feasibility …

Open Access Dissertations

This dissertation examined the critical role of human and social capital in the evolution of the NCAA Division I men's collegiate basketball product over time. Specifically, it sought to understand the characteristics of coaching networks that were consistently successful in perpetuating leader development over time, thereby theoretically replicating positive performance outcomes over long time spans. Interviews, content analyses and a literature search were performed to evaluate factors such as the processes of identification and selection of assistant coaches, the learning systems associated with their leader development, the strategies for their career advancement and growth, and the support structures of ongoing …

An Investigation Of Temporal Resolution Abilities In School-Aged Children With And Without Dyslexia, Elena Zaidan

Open Access Dissertations

Dyslexia is a clinical diagnosis often associated with phonological processing deficits. There are, however, other areas of concern, such as the presence of auditory temporal processing (ATP) disorders. One method of investigating ATP is the gap detection (GD) paradigm. This study investigated GD performance using the Gaps-in-Noise © (GIN) test in three groups of 30 children, aged 8 to 9 years. GD thresholds and gap identification scores (%) were determined for each participant. The three groups of participants included (Group I) children with dyslexia and phonological deficits, (Group II) children with dyslexia and no significant phonological deficits, and (Group III) …

Modifiable Risk Factors For Hypertensive Disorders Of Pregnancy Among Latina Women, Shannon Renee Turzanski Fortner

Open Access Dissertations

Hypertensive disorders of pregnancy affect approximately 8% of pregnancies, and can lead to serious complications for both mother and child. While Latinas are at two-fold increased risk of preeclampsia relative to non-Latina white women, little research on hypertension in pregnancy has been conducted in this population. Furthermore, there are few modifiable risk factors for hypertensive pregnancy. Therefore, we examined associations between psychosocial stress, physical activity, and pre-pregnancy BMI and gestational weight gain and hypertensive disorders of pregnancy using data from the Latina GDM Study, a prospective cohort study of 1,231 women. The first study evaluated the association between perceived stress …

Detrimental Effects Of Inactivity On Insulin Action, Brooke Rene Stephens

Open Access Dissertations

Inactivity reduces insulin action. Energy surplus causes similar reductions to insulin action. Unless energy intake is reduced to match low energy expenditure during inactivity, a concurrent energy surplus may account for the lower insulin action. This study evaluated the effect of inactivity (sitting) with and without energy surplus on insulin action. Fourteen young (26.1 ± 4.5 years (M ± SD)), lean (23.7 ± 7.1% fat), fit (VO 2peak = 49.1 ± 3.3 ml*kg -1 *min -1 ) men (n=7) and women (n=7) completed each of 3, 24-hour conditions: an active condition (i.e. high energy expenditure with energy intake matched to …

The Adoption Of Shamanic Healing Into The Biomedical Health Care System In The United States, Lori L. Thayer

Open Access Dissertations

Following cultural anthropological inquiry, this dissertation examines the adoption of shamanic healing techniques into Western medicine and the resultant hybrid modality of health care fostered by two disparate healing traditions. As the U.S. populace increasingly turns to alternative forms of healing in conjunction with, or in lieu of, conventional Western medicine, shamanic healing has been added to the list of recognized non-conventional therapies. Shamanism, once prevalent throughout most of the world in various cultural forms, is purported to be the oldest healing modality, dating back to the Upper Paleolithic in Siberia. Historical excoriation and extermination from religious and political dogma …
