Alterations In Tight Junctional Proteins And Their Effects On Pulmonary Inflammation, Joshua B. Lewis

Theses and Dissertations

The lungs represent one of the earliest interfaces for pathogens and noxious stimuli to interact with the body. As such, careful maintenance of the permeability barrier is vital in providing homeostasis within the lung. Essential to maintaining this barrier is the tight junction, which primarily acts as a paracellular seal and regulator of ionic transport, but also contributes to establishing cell polarity, cell-to-cell integrity, and regulating cell proliferation and differentiation. The loss of these tight junctions has been documented to result in alterations in inflammation, and ultimately the development of many respiratory disorders such as COPD, Asthma, ARDS, and pulmonary …

An Examination Of The 16pf Global Factors As Predictors Of The Scale Of Accurate Personality Prediction (Sapp), Maria Christina Mandina

Theses and Dissertations

The Scale of Accurate Personality Prediction (SAPP), first developed by Miller (2000), was designed to measure one’s self-knowledge regarding their personality traits. The SAPP was derived from the Sixteen Personality Factor Questionnaire (16PF) by means of comparing the differences between a respondent’s predicted and obtained scores on the 16PF. Numerous studies to date have examined both the reliability and validity of the SAPP. A recent study looked at the predictability of the SAPP score utilizing the 16 obtained primary scales of the 16PF (Mazur, 2015) so as to be able to derive a SAPP score directly from the obtained 16PF …

A Review Of The Potential Therapeutic Application Of Vagus Nerve Stimulation During Childbirth, Tanya Enderli

Theses and Dissertations

Mythology Of The Angry Black Man: An Analysis Of Cornelius Eady’S Brutal Imagination As A Rhetorical Counter-Narrative, Junior Ocasio

Theses and Dissertations

This thesis examines how Cornelius Eady’s book of poetry, Brutal Imagination, rhetorically serves as a counter-narrative to the fictional construction of Black characters blamed for committing crimes. Brutal Imagination gives voice to Mr. Zero, Eady’s name for the fictional character Susan Smith created in 1994, whom Smith blamed for kidnapping her children. Thus, by using a counter-narrative lens, this thesis analyzes how fictional creations can alter the socially constructed identity of the “angry” Black man.

Rights Of Nature And The Political Implications Of Post-Humanist Ecologies, Jaimie Kent

Theses and Dissertations

Several countries have adopted legal frameworks that recognize ‘nature,’ or nonhuman things in ‘nature,’ as rights-bearing entities in their own right. In this thesis, I ask what these laws can tell us about the possible political implications of post-humanist perspectives regarding nonhuman entities and ‘nature.’ To answer this question, I analyze the similarities and differences between recent post-humanist ecological perspectives (Bennett 2010; Latour 2014, 2004) and indigenous imaginaries that informed rights of nature laws in Ecuador, Bolivia, and New Zealand. This comparative analysis reveals a promising path for achieving sustainable relationships with nonhuman entities that promote environmental protection. Finally, I …
