American Blitzkrieg: Courtney Hodges and the Advance Toward Aachen (August 1 - September 12, 1944)

Description: This is an analysis of combat operations of US First Army under the command of Courtney Hodges, between August 1 and September 12, 1944, with an emphasis upon 1st, 4th, 9th, and 30th Divisions. However, other formations are necessarily discussed in order to maintain context. Indeed, many historians have failed to emphasize the complex interdependent nature of these efforts, and the traditional narrative has been distorted by inadequate situational awareness. This study argues that the army's op… more

Water-soluble Phosphors for Hypoxia Detection in Chemical and Biological Media

Description: Water-soluble Pt(II) phosphors exist predominantly for photophysical studies. However, fewer are known to be candidates for cisplatin derivatives. If such a molecule could exist, it would be efficient at not only destroying the cancerous cells which harm the body, but the destruction would also be traceable within the human body as it occurred. Herein, research accomplished in chemistry describes the photophysical properties of a water-soluble phosphor. Spectroscopically, this phosphor is uniqu… more

A Comparison of the Pittsburgh Sleep Quality Index, a New Sleep Questionnaire, and Sleep Diaries

Description: Self-report retrospective estimates of sleep behaviors are not as accurate as prospective estimates from sleep diaries, but are more practical for epidemiological studies. Therefore, it is important to evaluate the validity of retrospective measures and improve upon them. The current study compared sleep diaries to two self-report retrospective measures of sleep, the commonly used Pittsburgh Sleep Quality Index (PSQI) and a newly developed sleep questionnaire (SQ), which assessed weekday and w… more

A Silent Cry: Visualizing Data on Sex Trafficking

Description: In this era of globalization, human trafficking is emerging as a major theme, with rapid movement of information, capital and people across international borders. Despite the red alert over the issue, the crime of human trafficking remains highly unreported even in the most developed countries like United States of America. This silence over the issue in this country can be attributed to the lack of awareness about its prevalence in our own back yard and the measures available against it. This … more

Burushaski Case Marking, Agreement and Implications: an Analysis of the Hunza Dialect

Description: This thesis was written to explore the structural case patterns of the Burushaski sentence and to examine the different participant coding systems which appear between noun marking and verb agreement. Verb suffixes follow nominative alignment patterns of agreement, while the verb prefix agrees with the affected argument as determined by semantic relations, as opposed to syntactic ones. The agent noun phrase is directly marked when highly active or volitional, suggesting a system of agent markin… more

Effects of Peripheral Nerve Injury on the Cells of the Dorsal Root Ganglion: a Role for Primary Cilia

Description: Primary cilia are ubiquitous sensory organelles found on most cell types including cells of the dorsal root ganglia (DRG). The DRG are groups of peripheral neurons that relay sensory information from the periphery to the CNS. Other cell types in the DRG include a type of glial cell, the satellite glial cells (SGCs). The SGCs surround the DRG neurons and, with the neurons, form functional sensory units. Currently are no reports describing the numbers of DRG cells that have cilia. We found tha… more

The Effects of a Group Parent-coaching Package on the Behavior of Children with Autism and Their Parents

Description: Support for parents is an important part of treatment programs for children diagnosed with autism. Parent training programs have generally focused on prescribed goals in one-on-one training settings with measures directly related to the goals. Of interest here are the few studies that included collaborative goals, expanded measures, and group training. Benefits of such approaches include the establishment of natural communities of reinforcement and better understanding of the breadth of effects… more

Endogenous Information and Inter-state War Expansion

Description: Scholars have long debated the causes of late third party state joining in ongoing inter-state wars. This research has generally concluding that peace-time conditions, measured in terms of: third party capabilities; proximity to warring states; and inter-state alliances, are determining factors in the decision to join. However, these studies utilize theories derived from static pre-war measures of capabilities and motivation to explain late joining; indeed, the same measures that fail to predi… more

Zebrafish Von Willebrand Factor

Description: In humans, von Willebrand factor (vWF) is a key component in hemostasis and acts as a 'cellular adhesive' by letting the circulating platelets bind to exposed subendothelium. It also acts as a carrier and stabilizer of factor VIII (FVIII). A dysfunction or reduction of vWF leads to von Willebrand disease (vWD), resulting in bleeding phenotype which affects 1% of the population. Currently there are a variety of animal models used for the study of vWF and vWD; however, they do not possess the … more
