Haitian Representation In The Media: A Comparative Analysis Between An African American Owned Newspaper And A Mainstream Newspaper, Stephanie Jean-Baptiste

Master's Theses

Are the portrayals of Haitian immigrants in an African-American owned newspaper, different from their portrayal in a white owned newspaper? In this paper I examine newspaper articles covering Haitian immigrants and refugees. The articles selected were published in 2004 and sampled from the Chicago Tribune and the Chicago Defender. Although the journals have distinctive goals and market reach, there were similarities in their portrayal of Haitian immigrants. Both journals referred to Haitian immigrants as victims of Haiti’s failed democracy. However, each journal advertised the reception of this migrant group differently. The African American owned newspaper advertised inclusion, while the white-owned …

Building And Optimizing A Spectroelectrochemical System For The Study Of Shewanella Putrefaciens, Jonathan Muscolino

Master's Theses

Shewanellaceae are among the most widely studied electroactive microorganisms. This study reports on Shewanella putrefaciens under anaerobic conditions during applied potential while monitored by spectroscopy. The attachment of the microbe Shewanella putrefaciens onto an indium tin oxide electrode was found to occur after 2 hr of +0.2 V applied potential. Microbial detachment occurred with a 5 mV/s scan rate cyclic voltammogram from +0.2 V to -0.5 V to +0.2 V. This was confirmed through use of a spectroelectrochemical apparatus utilizing a standard 3 electrode setup with evanescent wave spectroscopy.

Feminist And Gay Male Politics: New Issues For Political Collaboration And Activism, Adam Hii

Master's Theses

This project looks at political collaboration between people who self-identify as gay men

and those who self-identify as feminists. These two groups have been political aligned on numerous issues since the 1970s. The goal of this project is to see on which issues that political collaboration will continue moving forward. This research draws extensively on oral interviews conducted with gay men and feminists, as well as the current work of national advocacy organizations to see where political interest is high, and where networks already exist to foster future advocacy efforts. By focusing on these areas, this project predicts which issues …

Phosphodiesterase Inhibition As A Mechanism Of Ion Channel Modulation By Celecoxib, Christina Jean Robakowski

Master's Theses

The overall objective of this thesis work is to determine the mechanism by which celecoxib modulates Kv7 potassium channels in vascular smooth muscle cells. The central hypothesis of the project is that celecoxib modulates Kv7 potassium channels in vascular smooth muscle cells through inhibition of phosphodiesterase 4 (PDE4, which catalyzes the breakdown of cyclic adenosine monophosphate (cAMP)), thereby activating a cAMP/protein kinase A (PKA) signaling pathway. The aims of this thesis targeted different points in the cAMP/PKA pathway with pharmacological interventions using whole cell perforated patch clamp electrophysiology and biochemical methods.

The data suggest multiple mechanisms by which celecoxib could …

Investigating The Regulatory Mechanisms By Which Arabinose And Sypa Control Biofilm Formation In Vibrio Fischeri, Sheila Paris

Master's Theses

Biofilms are surface-associated microbial communities surrounded by an extracellular matrix. Through biofilm formation, many pathogens and symbionts are able to colonize, survive, and persist in their host. A model system used to study biofilm formation is the symbiotic bacterium Vibrio fischeri, which colonizes its host, the squid Euprymna scolopes. Complex signaling between the squid and the bacteria is essential for the proper regulation of biofilm formation as well as for persistent colonization.

The signal(s) that promote host-relevant biofilm formation are as-yet unknown, but recently it was discovered that the sugar, L-arabinose, serves as a unique signal to promote biofilm formation …

A Bioluminescence Sensor Of Nlrp3 Inflammasome Activation, Michael Alexander Winek

Master's Theses

The innate immune system is many organisms first line of defense against pathogenic insult or tissue damage. This defense strategy is intent on restoring homeostasis upon perturbation. Upon activation of the innate immune system in humans, an oligomeric protein complex termed the “Inflammasome” forms in myeloid cells. The canonical output of activation of any subset of inflammasome is Caspase-1-mediated secretion of pro-inflammatory cytokines IL1β and IL18. Chronic or uncontrolled inflammasome activation is at the core of myriad economically burdening diseases. In many of these diseases, endogenous factors chronically engage the innate immune system. To study these diseases in in vivo, …

Structure-Function Relationship Between Quercetin, Its Methylated Derivatives And Cytotoxicity In Triple Negative Breast Cancer Cells, Jyoti Phatak

Master's Theses

Quercetin is a member of the flavonoid family, found in fruits and vegetables, and has

shown cytotoxic effects on many cancers, including breast cancer. Quercetin’s methylated derivatives, 3-O-methyl quercetin, pentamethyl quercetin, isorhamnetin, and tamarixetin, differ in their substitution patterns of the methyl capping at the 5-hydroxyl groups. Cell death assays performed on MDA-MB-231 cells showed increased cytotoxicity with quercetin and all its methylated derivatives, except pentamethyl quercetin, after 72 hours of treatment. Loss of the mitochondrial outer membrane potential (MOMP) was seen using a JC-1 assay after 15 min incubation with compounds, except for pentamethyl quercetin. We saw no change …

A Framing Analysis Of Latinos In The Facebook Pages Of News Organizations, Juliana Zapata Acosta

Master's Theses

This study of the Facebook pages of six legacy media organizations extended framing theory to apply to social media. In the study of 557 articles, four new frames and 10 new subframes were identified. The immigration frame and its two subframes, deportation and undocumented, dominated the coverage of Latinos during the period of the study. The politics frame was the second most dominant frame. This study updated the old data and found that no progress has been made, with the exception of a lesser use of the criminal frame. This improvement could be because the study included six months of …

The European Union is used as a case study along with two of its Member States that are in the process of transitioning to democracy from previous authoritarian regimes—Hungary and Romania. This thesis employs stealth authoritarian theory to analyze how a democratizing Member State may violate these laws and revert to authoritarian governance. It also critiques international enforcement mechanisms to consider their effectiveness to enforce their laws and norms as well as prevent an authoritarian reversal. Finally, cultural …

Power, Subjectivity, And Life In Spain: A Continuation Of Elite Power, Matthew Mason

Master's Theses

On December 20, Spain will hold national elections to determine the new prime minister and national and local parliaments. These elections will be another crossroads in the long history of Spain. The elections come about in a political and social atmosphere of ‘change’ and ‘regeneration,’ marked by the rise of two new political parties, Podemos and Ciudanos. These parties are the new forces in the political scene in Spain. This atmosphere of change is the result of the 2008 economic crisis. The economic crisis of 2008 was not only an economic crisis in Spain, but it provoked a political and …

The Multidimensionality Of Schoolgirl Dropouts In Rural Bangladesh, Tiffany Yancey

Master's Theses

This thesis outlines the underlying causes for girl dropouts in the secondary school system of rural Bangladesh and assesses the barriers that affect adolescent girls and their families. The complex dynamics of the historical context within the patriarchal-dominant structure of society creates a system that hinders girls’ education and forces them into marriage at an early age. Poverty and lack of parental involvement in schools, as well as societal traditions and lack of government infrastructure play an enormous role and are the main structural factors that are linked to schoolgirl dropouts in this study. This thesis also analyzes previous education …

The Tunisian Revolution: Empire And The Power Of The Multitude, Caroline A. Burns

Master's Theses

The self-immolation of Mohammed Bouazizi ignited the revolution that would oust Tunisian dictator Ben Ali in 2011. The momentum of the revolution in Tunisia spread ideas, tactics, and revolutionary chants across borders to various parts of the globe. The speed and intensity of the revolution dominated the attention of the unsuspecting global community. In order to understand the conditions under which this revolution transpired, I use Michael Hardt and Antonio Negri's theory of Empire to show how the contemporary global system functions. Through the historical development of Tunisia and concurrent rise of Empire emerges "the multitude," the heterogeneous manifestation of …

Europe’S Refugee Crisis: Assessing The Factors Preventing A Coordinated Eu Response, Ali Albassam

Master's Theses

In order to escape increasing political violence in the Middle East and Africa, many refugees are fleeing by sea to seek asylum in Europe. As a result, Europe has witnessed the highest influx of refugees since World War Two. European Union member states have scrambled for a solution, seemingly unable to form a collective response. The reemergence of nationalism amid the arrival of thousands of refugees not only clouds Europe’s moral compass, but also weakens the EU and its founding principles. In an effort to contribute to the protection of refugees and the EU and its values, this thesis aims …

Production And Harvest Of Microalgae In Wastewater Raceways With Resource Recycling, Alexander Colin Roberts

Master's Theses

Microalgae can be grown on municipal wastewater media to both treat the wastewater and produce feedstock for algae biofuel production. However the reliability of treatment must be demonstrated, as well as high areal algae productivity on recycled wastewater media and efficient sedimentation harvesting.

A pilot facility was operated with nine CO₂-supplemented raceway ponds, each with a 33-m² surface area and a 0.3-m depth, continuously from March 6, 2013 through September 24, 2014. The ponds were operated as three sets of triplicates with two sets continuously fed …

Ergonomics Analysis Of Touchscreen Utilization As A Function Of Preferred Hand And Gender, Jordan E. Odell

Master's Theses

The growth of touchscreen technology has changed the way users interface with a wide range of computing and communication products and systems. Examples range from personal tablets and laptops to industrial applications such as process control, point-of-sales, and ticketing kiosk systems. An important area of application is the automobile industry which is designing cars with touchscreen control panels to replace the previously designed mechanical knobs and buttons. However, interacting with touchscreens does not provide the same tactile feedback as physical mechanisms, therefore they require more precise movement and visual attention, which distracts the user from the primary task.

The purpose …

"Persephone's Contemporary Dilemma: Consent, Sexuality, And "Female Empowerment." [2015], Cassandra Elizabeth Cerjanic

Master's Theses

Greek mythology never strays very far from Western imagination. Though every few years literature involving the infamous Gods tapers off into the back of our collective minds, a resurgence soon follows. The late Romantic literary movement (as popularized by Lord Byron, Percy Bysshe Shelly, and John Keats) depended heavily upon Greco- Roman mythology to help illustrate characters that existed somewhere between the shadow of imagination and the truth of humanity. Perhaps in an attempt to harken back to Romanticism, contemporary poetry has once again given life to the Greek Gods. Mythological characters can be seen throughout the works of modern …

Then, several patterns are developed using the SSM to deal with consumer complaints. Each area, Advice, Appraisal, Commitment, Complaint, Compliance, Deed, Guideline, Gratification, Judgment, Model, Need, Ownership, Promotion, Rate, Review, Selling, Support, View, and Violation, is explored and the core knowledge of the concept of consumer complaints …

An Evaluation Of The Disposition Of R941000, A Tetrazolone-Telmisartan Analog: A Case Study Of The Suitability Of Tetrazolone As A Carboxylic Acid Bioisostere, Ryan Brant Murray

Master's Theses

Carboxylic acids are ubiquitous in medicinal compounds, such as nonsteroidal anti-inflammatories, statins, hypertensives, and anticoagulants. Despite their prolific use, unfavorable characteristics such as metabolic instability, poor membrane permeability, and toxicity have been associated with this moiety in some instances. Bioisosteres have been employed to attenuate these issues. However, bioisostere use can alter drug potency and disposition. Recently, our company demonstrated the feasibility of the tetrazolone moiety as a carboxylic acid bioisostere for the angiotensin II antagonist telmisartan. R941000 (telmisartan-tetrazolone analog) was a potent in vitro inhibitor of angiotensin II and possessed a similar disposition to telmisartan. To the best of …

Muslim Brothers Or Overstaying Guests? The Reception Of Syrian Refugees In Southeastern Turkey, Irem Karaçizmeli

Master's Theses

This thesis contextualizes the Syrian refugee issue in Turkey with an analysis of history and political discourse, and data drawn from a fieldwork conducted in Şanlıurfa, Turkey in 2015. The Islamist ruling party has staged a warm welcome for Syrian refugees. Their refugee regime, however, has remained weak in regards to law and policy. Retaining the geographical limitation stipulated in the 1951 United Nations Convention Relating to the Status of Refugees, Turks have attempted to locate the larger issue of hosting refugees into cultural notions of ‘guesthood’ rather than a developed refugee rights framework. The fieldwork discovers the lack of …

The study examined the direct effect of core self-evaluations in predicting work engagement as well as the interaction …

Screening Bioactive Molecules In Tetrahymena Thermophila Using Phagocytosis Determined By Flow Cytometry, Santosh Gummidipundi

Master's Theses

The evaluation of molecules that have potentially bioactive significance is an expanding field, but current screening assays are expensive and time consuming. Mammalian cell-based assays require aseptic techniques, complex media and long generation times. This thesis reports on an assay that incorporates Tetrahymena phagocytic ingestion and flow cytometry to evaluate several potentially bioactive molecules. Several factors that influenced optimal and reproducible results were analyzed. Seven potentially bioactive molecules (serotonin, norepinephrine, dopamine, morphine, colchicine, mexiletine and procainamide) were evaluated to determine their effect on phagocytosis by Tetrahymena. Assay results indicated that the phagocytic rate was unaffected by serotonin, norepinephrine, dopamine, and …

Mitochondrial Dysfunction And Lipid Metabolism Play A Major Role In The Lethality Caused By Developmental Alcohol Exposure, Payam Khodabakhshi

Master's Theses

Exposure to ethanol during development causes a variety of physical, developmental, and cognitive abnormalities. In humans, these symptoms are referred to as fetal alcohol syndrome (FAS) or fetal alcohol spectrum disorder (FASD). Previously, we established a Drosophila melanogaster model of FASD and showed that developmental ethanol exposure causes oxidative stress, and that this is a primary cause of the developmental lethality and delay associated with ethanol exposure. In this study, we investigate the role of fatty acid metabolism and lipid accumulation in connection to FASD. Here, we show that developmental ethanol exposure leads to dysregulation of fatty acid metabolism and …

The Relationship Between Organizational Justice And Various Dimensions Of Pay Satisfaction, Xinyi Li

Master's Theses

Pay satisfaction has been linked to important organizational outcomes such as work performance and turnover intentions. One way to predict employees’ pay satisfaction is through organizational justice. The purpose of this study was to examine the role of organizational justice perceptions in predicting various pay satisfaction dimensions. A sample of 107 employees participated in an online survey. Consistent with the hypotheses, results showed that pay-related distributive justice perceptions were a stronger predictor of pay level satisfaction than pay-related procedural justice perceptions, and that benefits-related procedural justice perceptions were a stronger predictor of benefits determination satisfaction and benefits administration satisfaction than …

Sex Role Type As A Predictor Of Gender Stereotype Use In The Evaluation Of Others: Does Being Atypical Preclude Sex Typing Of Others?, Jennifer L. Miller

Master's Theses

The purpose of this investigation was to see if sex role adherence could be used to predict gender stereotype use when viewing children. This was tested using a conceptual replication of an influential gender label study by Condry and Condry in which participants viewed a video of a baby crying in response to a startling event. Contrary to the Condry findings, this study found that participant perception of why a baby was crying was not consistent with the gender label given (consistent, being angry for the boy label and fearful for the girl label). Participant ratings did not vary significantly …

Formation Of Organic Films On Sulfuric Acid Solutions At Upper Troposphere And Lower Stratosphere Aerosol Acidities, Holger Saul Perez

Master's Theses

The effects of atmospheric aerosols on climate remain uncertain, especially where aerosol chemical composition is not well known. Chemical analysis of aerosols in the upper troposphere (UT) and lower stratosphere (LS) show sulfuric acid (40 - 80 wt. %) and water as the major components. However, recently, the presence of organic molecules was also reported in UT/LS aerosols which could produce a broad spectrum of chemical reactions that have the potential to alter the aerosol climate properties, so experiments were performed to examine these reactions. Propanal, individually or in mixtures with glyoxal and/or methylglyoxal, combined with sulfuric acid formed highly …

Chloroflexi: The Tale Of A Bacterium Present In Human And Environmental Habitats, Jayashree Sanjeeviraman

Master's Theses

The phylum Chloroflexi is relatively unexplored, with the majority of its representatives being uncultivable. As a result, these microorganisms have not been characterized beyond their morphology and simple staining reactions, making the study of this phylum extremely challenging. Chloroflexi has been detected in the human oral cavity of patients suffering from peri-implantitis and in the vagina of patients suffering from bacterial vaginosis. Interestingly, Chloroflexi is also present in various environments such as freshwater lakes, soil, deep-sea sponges, hot springs and activated wastewater. Isolation of an environmental Chloroflexi with high 16S rRNA gene homology to a human-associated counterpart could be used …

The Role Of Nitric Oxide In Skeletal Simulated Microgravity Response, Luan Tran

Master's Theses

Prolonged exposure to the space environment leads to bone loss. Using a ground-based model for microgravity (hind-limb unloading), it has been shown in rodents that proliferation and differentiation activity of osteoprogenitors are decreased with exposure to simulated microgravity (Kostenuik et al., 1997). Osteoblast mineralization activity has been shown to increase with nitric oxide supplementation (Afzal et al., 2004; Koyama et al., 2000). I hypothesized that the degenerative effects of microgravity exposure result from chronic changes in nitric oxide regulation in osteoprogenitors, and that supplementation with exogenous nitric oxide following exposure would ameliorate these changes. In 20 C57Bl/6 mice, hind-limb unloading …
