Biomechanical Assessment Of Ertl And Burgess Transtibial Amputation Techniques, Abbie Elthea Ferris

Dissertations

In this dissertation, a model was developed to predict the inertial properties of the shank and foot of persons with TTA and functional differences between Ertl and Burgess amputees during curb negotiation and the sit-to-stand tasks were evaluated. The developed inertial model was able to predict the shank and foot segment mass, COM location, and MOI more accurately than using the intact limb inertial properties. Used as inputs into inverse dynamics equations, the general model predictions produced joint moments which were also similar to the subject-specific measures. Thus, this model is a better predictor than the current method of using …

In recent years, there has been much concern over the decline of biologists who actually identify themselves to be naturalists, which negatively impacts the field of conservation and the study of biology as a whole. This could result in a decrease in individuals who participate in naturalist-like activities, such as informal environmental education and environmental volunteerism. The purpose of my study was to determine what discourse identities were held by naturalist development program participants, how these discourse identities related to their volunteer motives in environmental settings, and how discourse identity related to professional careers. I defined identity through the lens …

Investigating The Impact Of Reflexive Practices On College Students In A Science Laboratory Course, Chandrani Mishra

Dissertations

Emphasis on professional practices to develop students’ professionalism is currently a major focus of higher education. Studies have shown the benefits of reflexive practices in classroom to facilitate the development of students’ professional attitude or identity in some fields.

The Transformative Experiences Of Female Educators As A Catalyst For Social Change In The World, April D. Jordan

Dissertations

As social justice issues become known, one may be moved to act in the hopes of alleviating the conditions that burden marginalized and oppressed people. What is sometimes missing from the discourse when discussing oppressive issues is the role women play in counteracting such subjugation. Also essential, yet missing from the research, are studies that underscore the importance of educators fostering social action change outside of and apart from institutions of learning and curriculum planning. This qualitative study examined the lives of six, nontraditional, female educator intellectuals whose perceptions of self (identity) and the world were transformed by engaging in …

Mississippi continues to have one of the lowest rates and the weakest support in respect to breastfeeding in the nation (Centers for Disease Control and Prevention, 2014a). Hospital practices supporting breastfeeding such as the Ten Steps to Successful Breastfeeding (TSSB) can dramatically increase breastfeeding rates and duration (Rosenberg, Stull, Adler, Kasehagen, & Crivelli-Kovach, 2008). The aim of this study was to explore breastfeeding practices in Mississippi hospitals based on two levels of the Socio-Ecological Model: the organizational level (phase I) examined the hospital practices based on the level of implementation of the TSSB; the individual level (phase II) examined knowledge …

Macrobenthic Communities In The Northern Gulf Of Mexico Hypoxic Zone: Testing The Pearson-Rosenberg Model, Shivakumar Shivarudrappa

Dissertations

The Pearson and Rosenberg (P-R) conceptual model of macrobenthic succession was used to assess the impact of hypoxia (dissolved oxygen [DO] ≤ 2 mg/L) on the macrobenthic community on the continental shelf of northern Gulf of Mexico for the first time. The model uses a stress-response relationship between environmental parameters and the macrobenthic community to determine the ecological condition of the benthic habitat. The ecological significance of dissolved oxygen in a benthic habitat is well understood. In addition, the annual recurrence of bottom-water hypoxia on the Louisiana/Texas shelf during summer months is well documented.

The P-R model illustrates the decreasing …

Relationships Of Haemosporidian Parasites To Populations Of Their Avian Hosts In Eastern North America, Vincenzo Alexander Ellis

Dissertations

Avian Haemosporida are common, vector-transmitted blood parasites of birds throughout the world. During my dissertation research, I explored how multiple host species respond immunologically to natural infections in the wild (Chapter 1) and to experimental infections in the laboratory (Chapter 2). Despite their tractability as a model host-parasite system and a burgeoning literature on avian Haemosporida, little is known about how their populations interact across large areas (hereafter “regions”). I present data from parasite surveys of birds across eastern North America suggesting that continental parasite populations track host populations across the region, but also that the host breadth of a …

Implementation Of Positive Behavior Intervention And Support At The High School Level, Bernadette D. White

Dissertations

With schools having an ever-increasing interest in reducing acts of violence and reducing the incidence of out-of-school suspension, new interventions are constantly being sought. How the program is implemented can play a significant role in program effectiveness. Durlak (1998) found that many evaluation methods did not consider the implementation process because they were done after the implementation of the program. Whether an evidence-based intervention would have a positive effect depended on closely following the details of the implementation process (Durlak, 1998). This study was motivated by four research questions: (a) Was the process used to implement Positive Behavior Intervention and …

Student Involvement In Extracurricular Activities And Post-Secondary Education Placement, Courtney J. Martin

Dissertations

Extracurricular activities have been an important part of adolescents’ lives for generations (Kremer-Sadlik, Izquierdo, & Fatigante, 2010). Extracurricular activities take place outside of the classroom and result in several benefits to students (National Federation of State High School Associations [NFHS], 2010). With the recent recession in the United States, many school districts are having to find ways to cut budgets and are looking at eliminating extracurricular activities to save money (Lamb, 2011). Data from graduating seniors were reviewed in the largest accredited public school district in a Midwestern state. Graduates are required to take a post-follow up survey upon graduating …

Additionally, research questions were stated to determine which Tier II reading intervention yielded …

Factors Associated With High Risk Infant Follow-Up Attendance, Martha Grant Fuller

Dissertations

Prematurity is a significant public health problem and preterm infants face well described risks of adverse neurodevelopmental outcomes. Bronfenbrenner’s bioecological theory of development describes interactions between biological and environmental factors and explains how these interactions can impact development. Systematic follow-up of preterm, high-risk infants is recommended for early identification of problems and provision of interventions and support services. Most research on follow-up attendance has involved small, single sites. A retrospective analysis of population based data available in the California Children’s Services High Risk Infant Follow-up Quality of Care Initiative (HRIF-QCI) data system was performed to examine factors associated with attendance …
