An Investigation Of Violence-Related Trauma At Two Sites In The Pickwick Basin: Dust Cave (1lu496) And The O'Neal Site (1lu61), James Harvey Turner Ii
An Investigation Of Violence-Related Trauma At Two Sites In The Pickwick Basin: Dust Cave (1lu496) And The O'Neal Site (1lu61), James Harvey Turner Ii
Theses and Dissertations
Osteological evidence for violence has only in recent times been thoroughly investigated. Several kinds of traumas indicative of violence have been identified in human skeletal remains worldwide. Such traumas include scalping, embedded and/or associated projectile points, cranial fractures, parry fractures and defensive injuries, decapitation and dismemberment, and evidence of cannibalism. Analysis of traumas at Dust Cave (1LU496) and the O?Neal site (1LU61), two sites in northwestern Alabama with Middle and Late Archaic occupations, was undertaken. Violence-related traumas were observed at both sites. A highly significant difference exists in trauma patterns between the sites. Results were compared to research done on …
Diffuse Brain Injury Triggers Ultra-Rapid Perisomatic Traumatic Axonal Injury, Wallerian Change, And Non-Specific Inflammatory Responses, Brian Joseph Kelley
Diffuse Brain Injury Triggers Ultra-Rapid Perisomatic Traumatic Axonal Injury, Wallerian Change, And Non-Specific Inflammatory Responses, Brian Joseph Kelley
Theses and Dissertations
A significant component of diffuse brain injury (DBI) is diffuse axonal injury (DAI) which is responsible for the morbidity and mortality associated with this condition. DAI and its experimental counterpart traumatic axonal injury (TAI) result in scattered microscopic pathology characterized by focal impairment of axonal transport leading to progressive swelling and delayed axotomy. DBI-mediated perisomatic axotomy does not result in acute neuronal death suggesting that delayed axotomy was responsible for this unanticipated response. To evaluate this hypothesis, we examined the spatiotemporal progression of DBI-mediated perisomatic TAI. LM / TEM identified impaired axonal transport within 15 - 30 min post-injury. Perisomatic …
The Life Pattern Of People With Spinal Cord Injury, Ronald R. Alligood Ii
The Life Pattern Of People With Spinal Cord Injury, Ronald R. Alligood Ii
Theses and Dissertations
This aim of this study was to answer the research question: "What is the Life Pattern of the Person with Spinal Cord Injury?" The unitary appreciative inquiry design, which has conceptualized through Rogers' (1986) science of unitary human beings, provided an approach for understanding the phenomenon in the context of human wholeness. The data, obtained through the methodology of unitary appreciative inquiry, led to the development of individual synopses for each of the participants. Once the synopses were completed, a composite pattern profile was constructed by the researcher that was indicative of the life pattern of people with spinal cord …
The Effect Of Adding Drag-Reducing Polymers To Resuscitation Fluid During Hemorrhagic Shock On Skeletal Muscle Microcirculation, Geoffrey C. Alexander
The Effect Of Adding Drag-Reducing Polymers To Resuscitation Fluid During Hemorrhagic Shock On Skeletal Muscle Microcirculation, Geoffrey C. Alexander
Theses and Dissertations
Previous studies have shown an increase in survival when a minute amount of drag-reducing polymers were added to a resuscitation fluid. The purpose of this investigation was to examine the effect of adding a minute amount of the drag-reducing polymer polyethylene glycol to a resuscitation fluid, on the microcirculation of skeletal muscle during a volume-controlled hemorrhage model. The spinotrapezius muscle in twelve male Sprague Dawley rats was exteriorized for microvascular measurements of the arterioles. The diameters of the three levels of arterioles, interstitial fluid PO2, and RBC velocity in the feed arteriole were measured. Flow in the feed arteriole was …
Reflecting The Past And Shaping The Future: A Study Of Adolescent Schemas And Exposure To Community Violence, Monique Vulin Reynolds
Reflecting The Past And Shaping The Future: A Study Of Adolescent Schemas And Exposure To Community Violence, Monique Vulin Reynolds
Theses and Dissertations
Exposure to community violence is a pervasive problem among urban youth and has been associated with both internalizing and externalizing disorders. The mechanisms through which exposure to community violence impacts adolescent adjustment are unclear. A change in adolescent schemas has been proposed as a mechanism through which the impact occurs. The goals of this study were to develop a measure of relevant adolescent schemas and examine their relation to exposure to community violence. A sample of 320 5th and 8th graders were assessed and confirmatory factor analyses of the measure supported a three factor model, including self-schemas, world schemas and …
