Construction Of Bacterial Strains Containing A Plasmid Producing An Opossum-Based Anti-Venom Peptide For Low Cost Production Of The Peptide, Angela Cifelli

Master's Theses

A cost-effective therapy for snake bites and other biological toxins could save thousands of lives each year. A low-cost therapy can be achieved using a bacterial host that expresses a peptide that prevents death when administered after exposure to these toxins. A protein expressed in opossums, lethal toxin neutralizing factor (LTNF), provides the animal’s resistance to venom and a variety of other toxins. A small peptide fragment of this protein provides the same lifesaving properties as the full protein sequence. A synthetic copy of this peptide was tested in mice exposed to rattlesnake venom and showed lifesaving potential. The peptide …

Unified Software Engineering Reuse: A Methodology For Effective Software Reuse, Charles Allen Flood

Master's Theses

Software is a necessity in the modern world, and that need is continuously growing. As expensive as the creation of all this new software is, the maintenance costs are even greater. One solution to this problem is software reuse, whereby already written software can be applied to new problems after some modification, thus reducing the overall input of new code. The goal in traditional software reuse is to produce a piece of software with enough flexibility to be used at least twice. Unfortunately, there are many difficulties in achieving software reuse using modern programming techniques. Even software built specifically for …

Isolated Incidents: A Short Story Collection, Justin Bryant

Master's Theses

In my collection titled Isolated Incidents: A Short Story Collection, I explore the themes of isolation and loneliness while using dark humor and a satirical voice as an undercurrent to move the narratives. Isolation and loneliness intrigue me, because they are triggered and motivated by contradictory emotions inside of us. Fear, love, hate, and even nonchalant attitude and happiness can all mix to make us feel isolated even when we are not alone. People can be isolated when surrounded by others at a dinner table, or in a crowed bar, or even a small office filled with co-workers. Loneliness is …

Automated Classification To Improve The Efficiency Of Weeding Library Collections, Kiri Lou Wagstaff

Master's Theses

Studies have shown that library weeding (the selective removal of unused, worn, outdated, or irrelevant items) benefits patrons and increases circulation rates. However, the time required to review the collection and make weeding decisions presents a formidable obstacle. In this study, we empirically evaluated methods for automatically classifying weeding candidates. A data set containing 80,346 items from a large-scale academic library weeding project by Wesleyan University from 2011 to 2014 was used to train six machine learning classifiers to predict “Keep” or “Weed” for each candidate. We found statistically significant agreement (p = 0.001) between classifier predictions and librarian judgments …

Elucidating The Role Of Mastermind-Like 1 In The Degradation Of Myocyte Enhancer Factor 2c, Azia S. Evans

Master's Theses

Mastermind-like 1 (MAML1) is well characterized for its involvement in the Notch signaling pathway where it functions as a transcriptional co-activator and facilitates the degradation of the Notch intracellular domain (NICD). MAML1 has recently been implicated as a multifunctional protein that interacts with a variety of other signaling pathways, including Wnt-β-catenin, NF-B, and MEF2C (myocyte enhancer factor 2C). MEF2C is a member of the family of transcription factors involved in muscle cell differentiation and proliferation. MAML1 has previously been shown to activate MEF2C transcription. Given that MAML1 is responsible for degradation of the NICD, we wanted to know if MAML1 …

The Moderating Role Of Perceived Organizational Support And Perceived Supervisor Support On The Relationship Between Teamwork Behaviors And Affective Commitment, Carlie Ann Stephens

Master's Theses

Researchers have identified employee affective commitment as a key indicator of variables that are of great interest to organizations (Mowday, Porter, & Steers, 1982). Teamwork behaviors have been identified as predictors of affective commitment (Meyer, Stanley, Herscovitch, & Topolnytsky, 2002). However, very few studies have examined the moderating effect organizational and supervisor support may have on these relationships. The purpose of this study was to examine the moderating effects of perceived organizational support and perceived supervisor support on the relationship between teamwork behaviors and affective commitment. Results of a survey administered to 3,926 employees in a medical device company revealed …

Historical Trauma And Refugee Reception: Armenians And Syrian-Armenian Co-Ethnics, Nicole M. Campos

Master's Theses

This thesis considers the ways in which Armenian history has influenced integration of Syrian-Armenian refugees into Armenia due to the ongoing Syrian War. Ethnic Armenian outlooks were analyzed relative to the influx of Syrian refugees, particularly co-ethnic Syrian-Armenians. Field work in Armenia found a sustained cultural impression of Armenians’ Soviet membership and genocide. Findings suggest that recognizing the importance of history as it may or may not affect migration reception policies and attitudes is important to developing sustainable resettlement environments, at least until repatriation or third-country resettlement becomes an option to migrants. Ultimately, this thesis argues that more attention must …

Integrative Analysis Of Heterogeneous Genomics Data For Triple Negative Breast Cancer And High Grade Serous Ovarian Cancer, Abdelrahman Hosny Ibrahim

Master's Theses

The human body is made up of trillions of cells. Although all the human body cells contain the same DNA sequence inside their nuclei, each one carries out its own function. Normally, human cells grow and divide to form daughter cells as the body needs them. When cells grow old, or lose their ability to function properly, they die (in a very organized way called apoptosis or programmed cell death) and new cells take their role. Cancer is a disease that is caused by uncontrolled division of abnormal cells in some part of the body, breaking the natural process of …
