Analysis Of Commutativity With State-Chart Graph Representation Of Concurrent Programs., Kishore Debnath
Analysis Of Commutativity With State-Chart Graph Representation Of Concurrent Programs., Kishore Debnath
Electronic Theses and Dissertations
We present a new approach to check for Commutativity in concurrent programs from their run-time state-chart graphs. Two operations are said to be commutative if changing the order of their execution do not change the resultant effect on the working object. Commutative property is capable of boosting performance in concurrent transactions such that transactional concurrency is comparable to a non-blocking linearizable version of a similar data structure type. Transactional concurrency is a technique that analyses object semantics, as object states, to determine conflicts and recovery between conflicting operations. Processes that commute at object level can be executed concurrently at transaction …

Self-Assembly Of Rous Sarcoma Virus Capsid Protein, Probed By Solid-State Nmr And Tem, Jaekyun Jeon
Self-Assembly Of Rous Sarcoma Virus Capsid Protein, Probed By Solid-State Nmr And Tem, Jaekyun Jeon
Electronic Theses and Dissertations
The retroviral capsid protein (CA) is derived from the cleavage of Gag polyprotein during the maturation process, and self-assembles into a polymorphic fullerene-like shell encasing the viral genome materials. The orthoretroviral CAs, for instance, Human Immunodeficiency Virus (HIV) and Rous Sarcoma Virus (RSV) CA, has little similarity in their sequence composition but a common 3D structure. They form distinct capsid assembly in vivo and a range of similar assemblies in vitro. Due to the substantial polymorphism, such assemblies are not amenable for conventional structural biology techniques such as X-ray diffraction crystallography and cryo-electron microscopy (cryo-EM). Solid-state NMR spectroscopy is the …

The Relationship Among Post-Traumatic Growth, Religious Commitment, And Optimism In Adult Liberian Former Refugees And Internally Displaced Persons Traumatized By War-Related Events, Hannah Acquaye
Electronic Theses and Dissertations
One of the myriad consequences of war is displacement and refugee-ism. People become refugees when they no longer feel safe in their country of origin. Before, during, and after the journey towards safety, refugees and internally displaced persons (IDPs) endure several challenging circumstances which stretch their normal abilities to cope. In their efforts to cope, these people report several mental health challenges like sleeplessness, hypervigilance, anxiety, and depression. The reported mental health challenges are normal in this population; however, when they persist, they result in posttraumatic stress disorder. Surprisingly, some also report obtaining psychological growth due to their challenging circumstances. …
Examining Elementary Preservice Teacher Efficacy To Teach Writing In A Title 1 School: A Mixed Method Study Of A School-Based Teacher Education Course Intervention, Norine Blanch
Electronic Theses and Dissertations
As the demographics of the United States change, barriers persistently thwart efforts to ensure that all students, regardless of ethnicity, academic ability, or family circumstance, have equal opportunities to learn. Diminished retention rates of effective educators in Title 1 schools, elevated rates at which students from low-income families are taught by inexperienced or unqualified teachers and insufficient preparation of preservice teachers (PSTs) to teach in Title 1 schools are three such barriers. Policy reform organizations interested in improving the effectiveness of teacher education programs nationwide suggest forging strong clinical partnerships between universities and schools by relocating coursework to school-based settings …

A Mathematical Model For Feral Cat Ecology With Application To Disease., Jeff Sharpe
A Mathematical Model For Feral Cat Ecology With Application To Disease., Jeff Sharpe
Electronic Theses and Dissertations
We formulate and analyze a mathematical model for feral cats living in an isolated colony. The model contains compartments for kittens, adult females and adult males. Kittens are born at a rate proportional to the population of adult females and mature at equal rates into adult females and adult males. Adults compete with each other in a manner analogous to Lotka-Volterra competition. This competition comes in four forms, classified by gender. Native house cats, and their effects are also considered, including additional competition and abandonment into the feral population. Control measures are also modeled in the form of per-capita removal …

Habitat Selection In Transformed Landscapes And The Role Of Novel Ecosystems For Native Species Persistence, Lina Maria Sanchez Clavijo
Habitat Selection In Transformed Landscapes And The Role Of Novel Ecosystems For Native Species Persistence, Lina Maria Sanchez Clavijo
Electronic Theses and Dissertations
To understand native species persistence in transformed landscapes we must evaluate how individual behaviors interact with landscape structure through ecological processes such as habitat selection. Rapid, widespread landscape transformation may lead to a mismatch between habitat preference and quality, a phenomenon known as ecological traps that can have negative outcomes for populations. I applied this framework to the study of birds inhabiting landscapes dominated by forest remnants and shade coffee plantations, a tropical agroforestry system that retains important portions of native biodiversity. I used two different approaches to answer the question: What is the role of habitat selection in the …
An Investigation Of The Influence Of Cyber-Sexual Assault On The Experience Of Emotional Dysregulation, Depression, Post Traumatic Stress Disorder, And Trauma Guilt., Kelley Holladay
Electronic Theses and Dissertations
Over the past decade, cyber-sexual assault (also known as "nonconsensual pornography" or "revenge porn") has gained the attention of legal experts, the media, and most recently, the counseling profession. Whereas this nonconsensual sharing of sexually explicit images online, through social medial, or other forms of technology has been demonstrated to have significant impacts on victims, researchers have focused heavily upon the legality of these actions (i.e. should there be consequences for posting nude/semi-nude photos of non-consenting adults to the internet), but there has been a lack of attention to the mental health consequences of cyber-sexual assault on victims. The purpose …

Women With Influence: Creating A Powerful Woman Leader Identity Through Impression Management, Alex Rister
Women With Influence: Creating A Powerful Woman Leader Identity Through Impression Management, Alex Rister
Electronic Theses and Dissertations
Women hold few leadership roles in the workplace, and even though research indicates the positive benefits of more women in top positions, leadership has a longstanding association with masculine qualities. If a woman seeks a position of power, she may find herself negotiating between a conflicting "woman" identity and "leader" role performance. Previous literature on the subject offers two opposing perspectives. While the first school of thought emphasizes the importance of a woman assuming masculine characteristics to successfully assume leadership positions, a second body of research points to gender equality in leadership by driving industries and organizations to change. The …
