Does Affective Commitment Decrease The Level Of Stress Reported In Teachers? A Comparison Of Primary And Secondary School Teachers, Rhiannon Williams

The Plymouth Student Scientist

Occupational stress has been established as a predictor of low physical and psychological well-being. Organisational commitment can act as a buffer to the adverse effects of stress. Two types of commitment (affective and continuance) were studied to determine whether they have the same buffering effect. The ASSET questionnaire was completed by 112 teachers (52 primary, 60 secondary). The two types of commitment differed in their effect on stress, with high affective commitment leading to lower levels of stress and high continuance commitment resulting in higher levels of stress. No difference was found between the reported stress levels of primary and …

Attachment Theory As A Predictor Of Communicative Responses To Infidelity, Sandra Donovan

UNLV Theses, Dissertations, Professional Papers, and Capstones

This study set out to determine one’s communicative responses to infidelity as predicted by attachment style. Three hundred and ninety-two participants responded to a measure of attachment and were then randomly assigned to one of three scenarios: imagining a partner’s sexual infidelity, imagining a partner’s emotional infidelity and imagining a partner’s combined sexual and emotional infidelity. Participants then responded to a communicative response scale in reaction to the scenario. Results showed moderate support for attachment theory. Additional analysis revealed responses differed by infidelity type. Limitations and implications are discussed.

Characterization And Analysis Techniques Of A Dynamic In Vitro Blood-Brain Barrier Model, Ryan Everett Woodhouse

Biomedical Engineering

The blood-brain barrier (BBB) is responsible for maintaining the sensitive environment required by the brain. Although the BBB is necessary for proper functioning of the brain, it acts as an obstacle for doctors attempting to treat neurological disease. For a drug to act upon the brain, it must first pass through the discriminating BBB. For this reason, much research has been performed in recent years in order to create an in vitro model of the BBB on which drugs targeted for the central nervous system may be tested. The main goal of this project is to create an in vitro …

Improved Mobile Wireless In Vivo Surgical Robots: Modular Design, Experimental Results, And Analysis, Jeff Hawks

Department of Mechanical and Materials Engineering: Dissertations, Theses, and Student Research

Laparoscopic surgery results in superior patient outcomes as measured by less painful recovery and an earlier return to functional health compared to conventional open surgery. However, the difficulty of manipulating laparoscopic tools from outside the patient’s body generally limits these benefits to patients undergoing relatively simple procedures. The use of miniature in vivo robots that fit entirely inside the peritoneal cavity represents a novel approach to laparoscopic surgery. These robots enable more complex laparoscopic procedures, increasing the number of patients that benefit from laparoscopic surgery.

This thesis describes recent work focused on developing a modular wireless mobile platform that can …

Systematics And Molecular Phylogeny Of Two African Stem Borer Genera, Sciomesa Tams & Bowden And Carelis Bowden (Lepidoptera: Noctuidae), P. Moyal, B. Le Ru, D. Conlong, D. Cugala, B. Defabachew, T. Matama-Kauma, B. Pallangyo, J. Van Den Berg

All Peer-Reviewed Publications

Currently, the systematics of the African noctuid stem borers of the subtribe Sesamiina, which include major pests of cereals, is confused. In addition, their ecology is poorly known, as are the factors influencing their evolution. In this paper, we address these shortcomings for two genera of the Sesamiina, Sciomesa Tams & Bowden and Carelis Bowden. Mixed Bayesian phylogenetic analysis, which included their host plants and two mitochondrial genes, showed the genus Sciomesa to be polyphyletic. Two new genera were created, Pirateolea and Feraxinia. The genus Carelis proved to be paraphyletic and was subdivided into two sub-genera. The genera Sciomesa, Carelis …

Molecular Physics Of Electrical Double Layers In Electrochemical Capacitors, Guang Feng

All Dissertations

At present, electrochemical capacitors (ECs) are emerging as a novel type of energy storage devices and have attracted remarkable attention, due to their key characteristics, such as high power density and excellent durability. However, the moderate energy density of ECs restricts their widespread deployment in everyday technology. To surmount this limitation, four strategies are adopted: (1) to reduce the total system mass, (2) to increase the specific surface area of electrodes, (3) to enhance normalized capacitance, and (4) to expand the range of potentials applied on electrodes. The implementation of these approaches critically relies on the fundamental understanding of physical …

A Framework For Virtual Device Driver Development And Virtual Device-Based Performance Modeling, Zachary Jones

All Dissertations

Operating system virtualization tools such as VMWare, XEN, and Linux KVM export only minimally capable SVGA graphics adapters. This paper describes the design and implementation of system
that virtualizes high-performance graphics cards of arbitrary design to support the construction of authentic device drivers. Drivers written for the virtual cards can be used verbatim, without special function calls or kernel modifications, as drivers for real cards, should real cards of the same design exist. While this allows for arbitrary design, it is not able to model performance characteristics. We describe a new kernel system that allows for arbitrarily changing the performance …

Successional Vegetation In The Jocassee Gorges, South Carolina, Maxwell Boyle

All Dissertations

Multifactor ecosystem classification systems provide a three-pronged approach to identifying site units across the landscape based on repeating patterns of vegetation, soil, and geomorphology. Ecosystem classification models have been developed for a diversity of forest landscapes throughout North America, and are beneficial as an ecosystem management tool because the outcome yields data models that can be utilized by scientists and natural resource managers alike. In contrast to the enormous amount of classification studies undertaken in relatively stable, older-aged forests in eastern North America, there have been few studies that have employed multifactor classification techniques across a successional gradient, or heavily …

Predictors And Outcomes Of Occupational Commitment Profiles Among Nurses, Lindsay Sears

All Dissertations

Occupational turnover is a costly problem afflicting much of the nursing industry, and occupational commitment is a strong predictor of withdrawal from one's profession. Traditional organizational research examines most commitment-behavior relationships from a variable-centered perspective, focusing on the relationships between constructs. The present study adopts a configural, or person-centered approach aimed at identifying and describing clusters of individuals who share a similar set of occupational commitment mindsets. The present study extends current literature by a) investigating the existence of several occupational commitment profiles and describing their characteristics; b) examining situational and demographic predictors of profile membership; and c) testing differences …

Pathophysiology And Clinical Implications Of Lower Respiratory Tract Infection (Lrti) With Respiratory Enteric Orphan Virus (Reovirus): Background And Experimental Evidence, Maret E. Bernard

Graduate Theses, Dissertations, and Problem Reports (ETD)

Background. Respiratory viral infection early in life is a predominant factor in the inception of episodic wheezing and development of asthma amongst young children [1] and a serious health challenge. Previous studies of lower respiratory tract infections (LRTI) with respiratory syncytial virus (RSV) in animal models have indicated that early life viral exposure results in dysregulated neuroimmune interactions and altered synthesis/release of pro-inflammatory neuropeptides generating increased airway reactivity and neurogenic-inflammation. Similar to RSV, respiratory enteric orphan virus (Reovirus) is a common respiratory pathogen associated with pulmonary infections in children. Also, reovirus pulmonary infection has been shown to induce increased collagen …

Where Independence Meets Its Match: The Intersection Of Musical Identity, Record Promotion And College Radio Programming, Aaron J. Hawley

Graduate Theses, Dissertations, and Problem Reports (ETD)

College Radio has long been championed for being one of the last independent voices on a radio dial dominated by corporate for-profit stations. While corporate stations program their playlists towards whatever is on the charts, independent programming has long been part of the appeal of college radio. However, college radio music directors are in constant contact with record promoters whose sole goal is to get their clients' records played on-air. While a notion of independence is central to college radio's musical identity, these record promoters hold a great deal of power in the decision making process. Upon investigation at WVU …

The proposed algorithm includes two things the first is doubling the pervious 128 bits RC6 to 256 bits RC6 and the second adapting a Feistal network which is iterated 256 bits RC6 20 times. A desirable property of an encryption algorithm is that a …

Estimation Of Fracture Properties For A Horizontal Well With Multiple Hydraulic Fractures In Gas Shale, Ayodeji L Aboaba

Graduate Theses, Dissertations, and Problem Reports (ETD)

This research work presents a new method for estimating fracture properties for a horizontal well with multiple hydraulic fractures in shale gas reservoirs. This method utilizes the production data obtained during the linear flow period to provide reliable estimates of both fracture half-length and formation permeability.;The new method provides an excellent alternative to the conventional pressure transient analysis methods. It requires neither the existence of the elliptical flow nor the pseudoradial flow periods and thus reduces the impractical long times required for well testing in horizontal wells drilled in shale gas reservoirs. The conventional pressure transient analysis methods require an …

Is Punishment Relevant After All? A Prescription For Informing Juries Of The Consequence Of Conviction, Jeffrey Bellin

Faculty Publications

The American jury, once heralded as “the great corrective of law in its actual administration,” has suffered numerous setbacks in the modern era. As a result, jurors have largely become bystanders in a criminal justice system that relies on increasingly severe punishments to incarcerate tens of thousands of offenders each year. The overwhelming majority of cases are resolved short of trial and, even when trials occur, jurors are instructed to find only the facts necessary for legal guilt. Apart from this narrow task, jurors need not, in the eyes of the law, concern themselves with whether a conviction and subsequent …
