Birthing, Blackness, And The Body: Black Midwives And Experiential Continuities Of Institutional Racism, Keisha La'nesha Goode

Dissertations, Theses, and Capstone Projects

Within the last decade, historical and contemporary accounts of midwives, along with the efficacy of the Midwives Model of Care for pregnancy, childbirth and general women's health, have become increasing popular in mainstream publications and documentaries. Yet, very few of these accounts represent historical or contemporary black midwives (and midwives of color, more generally). Despite a long history of midwifery in the black community, black women currently represent less than 2% of the nation's reported 15,000 midwives. Relatedly, black women and infants experience the worst birth outcomes of any racial-ethnic cohort in the United States.

In the early 20th century, …

To better understand PKC-mediated pathway in breast cancer cells, it is important to identify the cellular substrates of PKC. The main focus of this work is to identify physiologically relevant cellular substrates of PKC in human breast cells and to characterize their roles in cancer-related phenotypes. The work to be described consists …

When Less Can Be More: Dual Task Effects In Stuttering And Fluent Adults, Naomi Nechama Eichorn

Dissertations, Theses, and Capstone Projects

The present study tested the counterintuitive hypothesis that engaging cognitive resources in a secondary task while speaking could benefit aspects of speech production. Effects of dual task conditions on speech fluency, rate, and error patterns were examined in stuttering and fluent speakers based on specific predictions derived from three related theoretical frameworks. Twenty fluent adults and 19 adults with confirmed diagnoses of stuttering participated in the study. All participants completed two baseline tasks: (1) a continuous speaking task in which spontaneous speech was produced in response to given prompts; and (2) a working memory (WM) task involving manipulations of WM …

Characterization Of Somatosensory Processing In Relation To Schizotypal Traits In A Sample Of Nonclinical Young Adults, Maureen Patricia Daly

Dissertations, Theses, and Capstone Projects

A core feature of schizophrenia spectrum disorders (SSDs) is a basic sensory (e.g., visual, auditory) processing disruption, yet few studies have examined somatosensation. The current dissertation project examined somatosensory processes among individuals at varying degrees of psychometric risk for psychosis using tactile texture and spatial discrimination and letter recognition tasks. Differential patterns of associations of somatosensory abilities with schizotypal trait dimensions (positive, negative, disorganized), independent of anxiety and depressive symptoms, and the relative contributions of bottom-up (peripheral and morphologic features) versus top-down (error types) processing were examined. It was hypothesized that: 1) performance on somatosensory tasks would account for significant …

A Meta-Analysis Of The Prediction Of Violence Among Adults With Mental Disorders, Hing Po Lam

Clinical Implications Of Binaural Interference: A Systematic Review Of The Literature, Michael Bergen

Dissertations, Theses, and Capstone Projects

A binaural advantage has been described in many studies over the past fifty years, although research also has demonstrated examples of a disadvantage known as binaural interference. The literature varies greatly in suggesting the incidence of binaural interference across all populations. It also raises questions about the underlying causes of this phenomenon, as well as whether age-related changes have an impact.

A systematic review was engaged to summarize the literature associated with binaural interference, to identify clinical implications of this body of literature, and to answer two research questions:

1) Does the literature describe changes in susceptibility to binaural interference …

Underprivileged Children In Port-Au-Prince, Haiti: Hearing And Academic Performance Of Children In Public Schools In Port Au Prince, Talia Meisel

Dissertations, Theses, and Capstone Projects

Hearing loss is estimated to affect more than 360 million people worldwide, 32% of whom are children. Children with hearing loss tend to develop compromised communicative abilities and also have been found to perform more poorly academically than their normal hearing peers. Because of the lack of medical care, children in third world countries are expected to have more difficulty hearing and learning in a classroom setting than children in first world countries due to higher incidences of conductive pathology. The purpose of this study is to assess the hearing ability of underprivileged children in kindergarten and primary schools in …

The Status Of Neonatal Hearing Screening In Sub-Saharan Africa: A Systematic Review, David Engelman

Dissertations, Theses, and Capstone Projects

Late identification of hearing loss can lead to speech and language delays, as well as social and academic difficulties. Neonatal hearing screening has reduced the age of identification of hearing loss in many developed countries. However, the practice is limited or non-existent in much of the developing world, such as sub-Saharan Africa. This systematic review used currently available literature to determine the status of neonatal hearing screening programs in sub-Saharan Africa and to develop a model program for the region. Results suggested a lack of neonatal hearing screening services in sub-Saharan Africa, stressing the need for more pilot hearing screening …

The Effects Of Morning Versus Evening Stretching Exercises In Hamstrings Flexibility Gains, Camron Einerman, Emily Eleff, Ana Ilijeska, Aliza Zinberg

Dissertations, Theses, and Capstone Projects

Many human physiological functions, including muscle flexibility, exhibit a pattern over a 24-hour period, known as circadian rhythm. Muscle flexibility and its circadian rhythm have been researched, though much more information is needed, especially regarding the hamstring muscle group. The object of this study was to determine if stretching at different times of the day results in differences in hamstring flexibility. Since muscles and joints are most flexible at night, greater ranges of motion should be available, allowing for a greater degree of stretching to take place. We hypothesize that when utilizing the optimal type, duration, and frequency of stretch, …

Examining The Association Of Medication Complexity With Health-Related Quality Of Life In Older Adults Receiving Community-Based Long Term Services And Supports, Claudia Ann Beck

Dissertations, Theses, and Capstone Projects

While the complexity of a medication regimen is a concern for all individuals, it is of significant concern for community-dwelling older adults who often require multiple medications to treat chronic health problems. Health related quality of life (HRQoL) has been identified as a key quality outcome measure when assessing care of older adults, particularly those with long-term care needs. Although the use of multiple medications has been widely explored in the literature, there is a paucity of data regarding the combination of several medication-related factors (number of active medications, therapeutic drug class, and medication regimen complexity) and HRQoL in older …

The Economic Causes And Consequences Of Overweight And Obesity In The United States, David Alan Lempert

Dissertations, Theses, and Capstone Projects

Obesity is a serious public health issue, associated with increased risks of premature death, heart disease, diabetes, cancer, breathing problems, arthritis, reproductive complications, and other diseases. There are economic causes and consequences of overweight and obesity. Researchers have recently suggested that the inability of Body Mass Index to appropriately distinguish between body fat and non-body fat components may lead to inaccurate results when analyzing the economics of obesity. I use Percentage Body Fat, defined as Body Fat divided by the sum of Fat-Free Mass and Body Fat, as the primary measure of body composition.

A growing body of literature explores …

Hot And Bothered: The Role Of Arousal And Rejection Sensitivity In Dual Process Sexual Decision Making For Gay And Bisexual Men, H Jonathon Rendina

Dissertations, Theses, and Capstone Projects

Dual process theories of decision making acknowledge the functioning of two distinct yet simultaneous processes termed System 1 and System 2. While System 1 relies more heavily on automatic and affective processing, System 2 relies more heavily on effortful and cognitive processing. Over the past several decades, many lines of research have shown the importance of System 1 in decision making and several prominent social psychological theories of interpersonal behavior, such as rejection sensitivity, rely on this dual distinction between affective and cognitive processing. Despite the prominence of dual process theories in many areas of psychology, the role of System …

This experiment’s aim was to test the effect of tDCS on recovery of skilled locomotion, recovery of balance, and recovery of grip strength after bilateral electrolytic lesions to sensorimotor cortices in mice. Tests employed in this experiment included the ladder test, grip test, and a balance pole test. We were able to show that 4 days of tDCS post brain injury in mice produced improvements …

Comparison Of An Intermittent Vs. Continuous Walking Program In Persons With Multiple Sclerosis Using The 6 Minute Walk Test: A Randomized Crossover Pilot Study, Stefanie Dicarrado, Bridget Dungan, Elizabeth Huallpa, Jacob Potrzeba

Dissertations, Theses, and Capstone Projects

Background: Difficulty with gait is one of the most common complaints of persons with MS (pwMS) and can be due to many causes, including neurogenic fatigue. Neurogenic fatigue is one of the most common MS symptoms, and can prevent pwMS from walking longer distances, thus limiting their ability to improve gait endurance. Intermittent walking, a technique where persons take breaks during walking rather than walking continuously, may allow for pwMS to walk longer distances due to less accrual of fatigue.

Objectives: The purpose of this pilot study was to examine whether a program of intermittent walking will result in a …

Benefit And Quality Of Life Improvement In Older Adult Cochlear Implant Recipients: A Review Of The Literature, Theresa Bartoldus

Dissertations, Theses, and Capstone Projects

The aging population is increasing rapidly, and in this group hearing loss is one of the most common disabilities. For those with severe to profound impairment, which occurs in approximately 10% of this population, conventional amplification often fails to provide adequate benefit. In these cases, a cochlear implant is indicated. The literature on cochlear implantation in older adults has shown that it offers significant speech perception and quality of life benefits to this population. However, it remains controversial despite ample research demonstrating these benefits, due to concerns about surgical complications and reduced benefit due to aging processes. Much literature also …
