Contribution To T He Onboard Context Sensitive Information System ( Of Commercial Aircraft, Wei Tan

Theses and Dissertations

Pilots currently use paper-based documentation and electronic systems (e.g., Electronic Centralized Aircraft Monitor (ECAM) for Airbus, and Engine Indication and Crew Alerting System (EICAS) for Boeing) to help them perform procedures to ensure safety, efficiency and comfort on commercial aircrafts. Management of interconnections among paper-based operational documents can be a challenge for pilots, especially when time pressure is high in normal, abnormal, and emergency situations. This dissertation is a contribution to the design of an Onboard Context-Sensitive Information System (OCSIS). The claim is that the use of contextual information facilitates access to appropriate operational content at the right time either …

The Psychological And Post-Colonial Approaches In Interpreting The Self And The Other In Heart Of Darkness And Things Fall Apart., Soumaya Ferchichi

Theses (Pre-2016)

To some critics, Things FallApart by Chinua Achebe, first published in 1958, comes to be the antithesis of Heart ofDarkness by Joseph Conrad, first published in 1899. In fact, this thesis will highlight Achebe's enthusiasm and nationalism that lead him to create a vivid picture of the African individual who is presented as belonging to a rich heritage of unique and complex African tradition. Achebe's characterization and representation of Africans in his novel is thought to be an ardent response to Conrad's assumed or perceived "racism." Yet, this thesis will discuss this dispute by giving new evidence to support Conrad's …

The basis of this research was to investigate the concentration of trace metals in the Ship Channel of Houston. Houston is known for its oil and gas refineries and also the heavy metals that might be discharged through waste associated with surrounding industries. The Ship Channel has a large amount …

Evaluation Of Equivalence Relations: Models Of Assessment And Best Practice, Dawn Amber Seefeldt

Dissertations

Due to changing age demographics in the United States, by 2050, an estimated 62.1 Americans will be over the age of 65 and the number of Americans with cognitive impairment, such as Alzheimer’s disease, will increase drastically as well (Alzheimer’s Association, 2014; Ortman, Velkoff, & Hogan, 2014). Once a diagnosis or behavioral indicators of cognitive impairment are present, it would be beneficial to apply a treatment package that promotes the maintenance or re-establishment of stimulus control in the environment. From a behavioral perspective, stimulus control aids in learning and memory through both respondent and operant conditioning. In the current study, …

A Quantified Approach To The Functional Longevity Of Geosynthetic Rolled Erosion Control Products (Grecps), Drew A. Loizeaux

Masters Theses and Doctoral Dissertations

Geosynthetic Rolled Erosion Control Products (GRECPs) have been utilized for decades in a multitude of applications to mitigate erosion resulting from land disturbance in civil construction projects. GRECPs vary from one type to another, ranging in performance and design life due to their composition and intended purpose. The coverage and durability of the GRECP are fundamental properties that can predict performance and fitness for use. Both coverage and durability will degrade over the design life of the GRECP to the point that fitness for use is unacceptable for the intended application. A standard approach is needed to quantify this material …

Problem Solving And Tool Use In Three Species Of Otter, Robert F. Gormley

Masters Theses and Doctoral Dissertations

Sea otters are well known tool users, yet the cognitive capacities of other otter species have been sparsely studied. Precedent exists for non-tool using species closely related to native tool users to display comparable abilities under experimental conditions. The social intelligence hypothesis predicts complex cognitive capacities in socially complex species. Using the Aesop’s Fable paradigm – wherein subjects drop stones into a cylinder half-filled with water to acquire floating out-of-reach food items – I assessed North American river otters’, Asian small-clawed otters, and giant river otters abilities to solve a novel tool-mediated problem. Sticks and water were presented with the …

The Plymouth Student Scientist

The ability of the chemotherapeutic agents namely etoposide and vincristine to cause cytotoxic and genotoxic damage to the human lymphoblastoid cell line, TK6, was at the centre of this study. Four different cytotoxic assays were tested for their ability to assess the cytotoxicity of the agents as well as two genotoxic assays to examine their ability to induce DNA damage. The TK6 cell line was exposed to increasing doses of the chemotherapeutic agents and cytoxicity assessed by in vitro trypan blue, neutral red uptake, LDH leakage and the glucose oxidase assays. The trypan blue assay was deemed to be the …

Exposure To Predator Kairomones Influences Egg Number And Size In Littorina Littorea, Jessica Raynor, Simon Rundle

The Plymouth Student Scientist

Predator kairomones play an important role in intertidal ecosystems, but knowledge on their potential role in influencing maternal effects is lacking. The aim of this study was to test whether egg production by female Littorina littorea was influenced by short-term exposure to predator kairomones before egg laying. Laboratory populations were exposed to predator cues from the intertidal crab Carcinus maenas for nine days, and egg number, egg size, and survivorship of the offspring were measured and compared with those from reference populations. Snails exposed to predator cues produced significantly more eggs, which were also significantly smaller than those produced from …

The Association Of Microstructural Connectivity In The Brain And Auditory Modulation Of Representational Momentum, Emma Theobald

The Plymouth Student Scientist

Perceived displacement from an object’s forward trajectory results in a representational momentum (RM) effect. In a behavioural task, participants watched a video of an actor reaching for/withdrawing from an object after hearing ‘I’ll take it’ or ‘I’ll leave it’, which was either congruent or incongruent with the subsequent action witnessed. The knowledge of other people’s intentions through auditory cues and then the predictions of their actions have been found to create an effect on the strength of RM experienced. The degree to which this auditory information affects the RM effect differs for each individual. This variation could, at least partially, …

Electronic Theses and Dissertations

The development of sight words is essential for individuals with significant disability. There is a plethora of research highlighting the acquisition of sight words for this population but to date, most focus on teacher led interventions (Browder, Algrim-Delzell, Spooner, Mims, & Baker, 2009). This study investigated the use of computer technology vs. one-on-one instruction targeting sight words acquisition for a student with a significant disability. Results showed the participant indicated improved performance using the computer based intervention versus the constant time delay instructor led intervention.

Modifying A Cow-Calf Biophysical Simulation Model For Analyses Of Alternative Enterprises, Jennifer L. Lutes

Graduate Theses and Dissertations

Cow-calf producers in the United States, tasked with providing beef calves for the beef industry, have had a multitude of difficulties to overcome in recent years. Producers in northwest Arkansas were negatively impacted by high hay prices coupled with low beef cattle market prices due to severe drought experienced in portions of 2010, 2011, and 2012. During this time they also faced high grain prices, due to a record low harvest, combined with portions of the corn harvest diverted from human and animal feed to ethanol production. Tight lending policies of this time, reminiscent of the housing market crash in …

Training Deictic Relations To Children With Developmental Delays Through The Use Of The Peak Relational Training System, Dena Larae Kime

Theses

Children with developmental delays often do not acquire perspective taking skills without training. These skills are imperative to the ability to relate to others socially and the development of appropriate social behavior. They may lack the ability to recognize that another person’s view may differ from their own, or that reality may differ from appearance. This study used deictic relational training to aid in the development of a ‘Theory of Mind’ and the acquisition of perspective taking skills. The PEAK relational training system was used in a special education classroom to train YOU and I relations, as well as YOU …

Sophorolipid Production From Lignocellulosic Biomass Feedstocks, Abdul Samad

Theses

The present study investigated the feasibility of production of sophorolipids (SLs) using yeast Candida bombicola grown on hydrolysates derived lignocellulosic feedstock either with or without supplementing oil as extra carbon source. Several researchers have reported using pure sugars and various oil sources for producing SLs which makes them expensive for scale-up and commercial production. In order to make the production process truly sustainable and renewable, we used feedstocks such as sweet sorghum bagasse, corn fiber and corn stover. Without oil supplementation, the cell densities at the end of day-8 was recorded as 9.2, 9.8 and 10.8 g/L for hydrolysate derived …

Improving Evaluation In Nonprofit Organizations: A Study Of How Evaluation Requests For Proposals Are Developed, Responded To, And Fulfilled, Nakia S. Matthews

Dissertations

It is often necessary for nonprofit organizations (NPOs) to formulate a Request for Proposal (RFP) to procure essential contracted services. This is most common when seeking the services of an external evaluator. Since most NPOs do not have internal evaluation staff, developing an appropriate RFP can be quite challenging. With limited literature and resources to guide NPOs on how to prepare RFPs, the process for procuring qualified evaluators can be even more daunting. This lack of resources and supports can lead to insufficient or incomplete RFPs, subsequently narrowing the pool of qualified potential bidders and reducing the extent to which …

Mountain Big Sagebrush (Artemisia Tridentata Ssp Vaseyana) Seed Production, Melissa L. Landeen

Theses and Dissertations

Big sagebrush (Artemisia tridentata Nutt.) is the most widespread and common shrub in the sagebrush biome of western North America. Of the three most common subspecies of big sagebrush (Artemisia tridentata), mountain big sagebrush (ssp. vaseyana; MBS) is the most resilient to disturbance, but still requires favorable climactic conditions and a viable post-fire seedbank for successful unassisted recovery. This study was designed to assess MBS seed production throughout post-fire recovery. We performed 2 pilot studies to develop methods for estimating seed production and plant age. The results of the pilot studies and a space-for-time substitution strategy were used to measure …

A Corpus-Based Analysis Of Russian Word Order Patterns, Stephanie Kay Billings

Theses and Dissertations

Some scholars say that Russian syntax has free word order. However, other researchers claim that the basic word order of Russian is Subject, Verb, Object (SVO). Some researchers also assert that the use of different word orders may be influenced by various factors, including positions of discourse topic and focus, and register (spoken, fiction, academic, non-academic). In addition, corpora have been shown to be useful tools in gathering empirical linguistic data, and modern advances in computing have made corpora freely available and their use widespread. The Russian National Corpus is a large corpus of Russian that is widely used and …

Audience Participation In Blue Man Group: Success Through Authentic Character, Adaptable Narrative, And Accessible Space, Haley Lauren Flanders

Theses and Dissertations

The relationship between performer and spectator is a constant topic in theatre since audiences are essential to any performance. Some contemporary performances strive to blur the line between the two by allowing audiences to participate during the show. Often, audience participation is despised and therefore avoided by spectators and theatre practitioners. However, Blue Man Group thrives on it due to their authentic character, adaptable narrative, and accessible space. Through my examination of the show as an audience member, I theorize that these three elements control the audience's willingness to participate in the production and in turn make the entire experience …

Functional Characterization Of Aggregatibacter Actinomycetemcomitans Qsebc : A Bacterial Adrengeric Receptor And Global Regulator Of Virulence., Whitney Weigel

Electronic Theses and Dissertations

In order for a pathogen to successfully colonize the host, it must be able to acquire essential nutrients and regulate gene expression to respond to environmental fluctuations. One mechanism bacteria have evolved in order to detect these fluctuations and respond is the two component signal transduction systems (TCS). Aggregatibacter actinomycetemcomitans, a dental commensal associated with localized aggressive periodontitis, contains a TCS designated QseBC that was previously shown to regulate expression of several iron acquisition genes, biofilm formation and virulence, but the activating signal was unknown []. QseBC is a conserved TCS in the Enterobacteriaceae and Pasteurellaceae, but the activating signal …

Effects Of Resistance Training And Creatine Monohydrate On Doxorubicin-Induced Muscle Dysfunction, Eric Christopher Bredahl

Dissertations

Doxorubicin (DOX) is a powerful chemotherapy agent that is associated with a number of deleterious side effects, including skeletal muscle dysfunction. The exact mechanisms behind the observed skeletal muscle dysfunction have yet to be fully understood. Nonetheless, the observed myotoxicity is believed to be the result of an increased oxidative stress. Resistance training (RT) has been shown to preserve skeletal muscle function in DOX treated muscles. Conversely, creatine (Cr) has been shown to improve skeletal muscle function. Yet, there has been no investigation into the effect of combined RT and Cr on DOX-induced muscle dysfunction. Thus, the possibility exists that …

The Effectiveness, Usability, And Motivational Characteristics Of Using Animated Role- Playing Situational Simulation Programs For Air War College Distance Learning Curriculum, Dennis Michael Armstrong

Dissertations

This study examined perceived effectiveness, usability, and motivational characteristics of using animated role playing situational simulations for Air War College distance learning (AWC/DL). The AWC/DL curriculum provides education to senior military officers who are geographically dispersed around the world with varying degrees of internet connectivity, creating specific limitations as to what methods of instruction are viable. An additional challenge is the very high student-to-teacher ratio (620:1). Traditionally, the AWC/DL program relied on text-based readings and tests to teach and evaluate students. Simulations might provide a realistic and valuable augmentation to the curriculum. The key potential advantages of adding simulations are …

The Legends Of Bigfoot: Or How I Regained My Manhood, Blaine Mccarty

Master of Arts in American Studies Capstones

Masculinity is a culturally defined identity that exists with no single way to express it. However, the cultural politics police masculinity to appear natural and non-changing, but masculinity changes over history influenced by events and the culture from which it gets its definition. Because of this twofold influence on the identity, there is a constant struggle of the appropriate ways to express masculinity in its attempt to normalize itself by defining what is and is not masculine. This work examines how Bigfoot, the hairy fabled monster, embodies conversations about masculinity during a shift in the masculine identity in a constantly …

Preventing Thymus Involution In K5.Cyclin D1 Transgenic Mice Sustains The Naïve T Cell Compartment With Age, Michelle L. Bolner

Dissertations and Theses (Open Access)

The thymus maintains T cell receptor (TCR) repertoire diversity through perpetual release of self-MHC restricted naive T cells. However, thymus involution during the aging process reduces naïve T cell output, leading to defective immune responsiveness to newly encountered antigens. We have found that early thymus involution precipitates the age-associated shift favoring memory T cell dominancy in young control mice. Furthermore, we have shown that age-related thymus involution is prevented in mice expressing a keratin 5 promoter-driven Cyclin D1 (K5.D1) transgene in thymic epithelial cells (TECs). Thymopoiesis occurs normally in K5.D1 transgenic thymi and sustains T cell output to prevent the …

Liberty, Equality, Indebtedness: Thomas Jefferson, John Adams And The Problem Of Debt In A Revolutionary Age, Martha Salazar Cantu

Theses and Dissertations

In this thesis I examine how the issue of debt contributed to the political tensions between the New England region and the Chesapeake region during the Revolutionary Age. The merging of the two regions’ economies into one federal union caused political divisions, which remained beyond the period of the Early Republic. Examining the cultural attitudes of each region towards debt provides a better understanding of the political problems between these two regions. The integration of the consignment culture of the Southern states with the Puritan ethic of the New England states caused economic difficulties for the young Republic. The research …

The species Triatoma gerstaeckeri is identified as the primary vector of T. cruzi within the Rio Grande Valley. Species of Triatoma gerstaeckeri were trapped in La Sal del Rey National Refuge in 2012 and 2013.

Data indicates a seasonal dispersal pattern of activity for T. gerstaeckeri. Optimal time of capture was between 1-2 hours after sunset. Different methods were utilized to determine the best combination of lures. Results indicate that the UV-light alone is …

Activation Of Microglia In The Rotenone Lymnaea Stagnalis Model Of Parkinson's Disease, Xiomara Galvan

Theses and Dissertations

Parkinson’s disease (PD) is the most common irreversible neurodegenerative movement disorder affecting approximately ten million people worldwide. In the central nervous system (CNS), PD is known by the selective loss of Dopamine (DA) cells of the substantia nigra pars compacta. Although the disease has been very widely studied, the underlying mechanisms are not yet understood. Several hypotheses have arisen as result of injury of the mitochondria, some experiments include microglia activation, microtubule damage, and reactive oxidative species, which all result in the death of DA cells. The theory of microglia activation upon inflammation was explored in this study. Using the …

A Handcrafted Multi-Branch Nerve Scaffold For In Vivo Peripheral Nerve Regeneration, Ridwan Fayaz Hossain

Theses and Dissertations

Arm and leg peripheral nerve injuries contribute largely to functional disability. These injuries seldom affect a single-line nerve; rather the injury goes beyond and disrupts the nerve tissue across multiple nerve paths. Here we investigate handcrafted PDMS based multi-branch nerve guidance conduit, which addresses this crucial branching from the sciatic nerve to aid with the regeneration to their appropriate distal targets. The design concept of the developed multiple branch nerve scaffolds is not specific for the sciatic nerve but can be modified for general use of all peripheral nerves and additional applications. Microchannels are also fabricated into a device in …
