Evaluation Of Lane Use Management Strategies, Chaitanya Paleti Siva Sai Krishna

Open Access Theses

The limited funding available for roadway capacity expansion and the growing funding gap, in conjunction with the increasing congestion, creates a critical need for innovative lane use management options. Various cost-effective lane use management strategies have been implemented in the United States and worldwide to address these challenges. However, these strategies have their own costs, operational characteristics, and additional requirements for field deployment. Hence, there is a need for systematic methodologies to evaluate lane use management strategies.

In this thesis, a systematic simulation-based methodology is proposed to evaluate lane use management strategies. It involves identifying traffic corridors that are suitable …

Advice On Facebook: Channel Effects On The Evaluation Of Advice, Douglas E. Pruim

Open Access Theses

This thesis explores the evaluation of advice given in comments on Facebook status updates. To date, most research on advice has focused on dyadic, face-to-face interactions. The masspersonal channel of Facebook introduces a public into advice exchanges, including not only an audience but multiple advisors. The current study extends advice response theory by examining how advice recipients are affected by perceived consensus and tailoring in advice messages, and by the trait of conformity or the desire to conform to others' opinions. Participants (N = 269) completed questionnaires about past status updates on Facebook in which they disclosed a problem and …

Growth Of Post-Weaned Grazing Dairy Heifers When Evaluating The Effects Of Providing Shade Or Parasite Control, Mohammad W. Sahar

Open Access Theses

Reduced heat stress and lower gastrointestinal parasite loads can increase growth rate in heifers, potentially reducing the age at first breeding and lowering the costs associated with raising replacement dairy heifers. Providing shade is a recommended practice for reducing heat stress of grazing animals and is considered important for their wellbeing and productivity. However, limited information is available on the growth performance of young grazing dairy heifers when they are provided shade. Likewise, numerous products exist to prevent gastrointestinal parasites in animals. The development of new anthelmintic products, such as LongRange® (eprinomectin), increase the need for research to help understand …

Evaluating Intensity As A Controller Function For Nextgen Scenarios With Increased Capacity, Caitlin Anne Surakitbanharn

Open Access Theses

Automated separation assurance is the most mature concept to handle increasing airspace traffic and capacity needs, yet the system lacks a way to pre-emptively identify aircraft separation problems. The intensity control measure looks to find situations where if an aircraft pair makes an unplanned change in heading or altitude at the wrong moment, an unrecoverable situation arises. This research analyzes static, open loop air traffic data in an en-route sector to determine how many high intensity aircraft pairs (HIP) exist per minute, and if the intensity measure is a safely manageable function for air traffic controllers. It is found that …

La Leche League, The Media, And The Nursing Mother: A Broader Perspective On Persona Theory, Erin F Doss

Open Access Dissertations

This dissertation builds on current breastfeeding-related scholarship by suggesting that the lived experiences of nursing mothers could be effective arguments for initial and continued breastfeeding. To do this, I analyzed archival materials related to La Leche League, specifically League newsletters, and media articles from publications across the United States to determine how the "nursing mother" functioned as a persona throughout the second half of the twentieth century. First, in my analysis of League newsletters I theorized a new category of personae, the constitutive persona, which includes personae used by a collective to attract new members and provide them with language …

Strategic Flexibility, Kihyung Kim

Open Access Dissertations

A flexible system is defined as one that can change the entity's stance, capability or status reacting to a change of the entity's environment. Flexibility has gathered the attention of academic researchers and industry practitioners as an efficient approach to cope with today's volatile environment. As the environments become more unpredictable and volatile, it is imperative for a flexible system to respond quickly to a change in its circumstance. How much flexibility is embedded into the system also has a critical impact on the long-term effectiveness of the flexible system. Moreover, this research focuses on the strategic environment where a …

Multidimensional Approach To Comparative Avian Visual Systems, Bret Alan Moore

Open Access Dissertations

Since the birth of visual ecology, comparative studies on how birds see their world have been limited to a small number of species and tended to focus on a single visual trait. This approach has constrained our ability to understand the diversity and evolution of the avian visual system. The goal of this dissertation was to characterize multiple visual dimensions on bird groups that are highly speciouse (e.g., Passeriformes), and test some hypotheses and predictions, using modern comparative tools, on the relationship between different visual traits and their association with visual information sampling behaviors. First, I developed a novel method …

This approach emphasizes the legitimacy of a group's cultural heritage, helps to associate abstract academic knowledge with the group's sociocultural context, seeks to incorporate a variety of strategies to engage students who have different learning styles, and strives to integrate multicultural information in the educational contents, among other considerations. ^ In this work, I explore the outcomes of a culturally responsive introductory engineering short course that I developed and taught to Tibetan students at Tibetan Children's Village of Selakui (in Uttarakhand, India). Based on my …

Explaining Associations Between Relational Turbulence, Communal Coping, Stressors, And Relational Satisfaction During Military Reunions: At-Home Partners' Perspectives, Jennifer Sue Owlett

Open Access Dissertations

The current study examined how 179 romantic partners of U.S. service members perceived that they and their service members experienced the reintegration transition following a recent deployment. The relational turbulence model (Solomon & Knobloch, 2004) and the theoretical model of communal coping (TMCC; Afifi, Hutchinson, & Krouse, 2006) were used to frame this study. These frameworks had not been previously joined in this context. A revised communal coping measure was constructed to examine 17 hypotheses and 8 research questions because of challenges with the construct and external validity in prior measures. Participants completed an online questionnaire that assessed their perceptions …

Energy Production, Distribution, And Pollution Controls: Combining Engineering And Economic Analysis To Enhance Efficiency And Policy Design, David F. Perkis

Open Access Dissertations

Three published articles are presented which focus on enhancing various aspects of the energy supply chain. While each paper adopts a different methodology, all three combine engineering data and/or techniques with economic analysis to improve efficiency or policy design within energy markets. ^ The first paper combines a chemical engineering plant design model with an economic assessment of product enhancements within an ethanol production facility. While a new chemical process is shown to achieve greater ethanol yields, the animal feed by-products are denatured and decrease in value due to the degradation of a key nutritional amino acid. Overall, yield increases …

Acquisition, Retention And Transfer Of Heavy Equipment Operator Skills Through Simulator Training, Chung Yin So

Open Access Dissertations

Initiatives and collaborations among heavy construction equipment manufacturing companies and training technology firms to develop and employ simulators for varied training purposes are becoming commonplace. However, human factors research on simulator training for operators of construction equipment is still sparse. For simulator training to be effective, it is necessary to understand how skills are learned using the simulator, how those skills are transferred to other tasks, devices, and real scenarios, and how well skills are retained after simulator training. ^ This research is on skill development, specifically as it applies to operator training for two specific types of heavy construction …

The literature review drew from the fields of college student development, family studies, communication, and nursing. Data were …

Role Of Group Ii Metabotropic Glutamate Receptor Subtype 2 (Mglur2) In Appetitive And Consummatory Aspects Of Ethanol Reinforcement, Kyle Allyson Windisch

Open Access Dissertations

Background: Group II metabotropic glutamate receptors (mGluR2/3) are predominately presynaptically located G_i/o coupled receptors that are highly expressed in the cortex, nucleus accumbens, amygdala, and hippocampus. Previous studies suggest that group II mGluRs are involved in regulating ethanol (EtOH) consumption and seeking following extinction (Backstrom and Hyytia, 2005; Kufahl, et al., 2011). The sipper tube model, which allows for procedural separation of seeking and consumption, was used to further clarify the role of mGluR2/3 in EtOH-seeking and consumption. The non-selective group II mGluR agonist LY379268 (LY37) and selective mGluR2 positive allosteric modulator (PAM) BINA were used to determine the …

Relationships Between Lexical Proficiency And L2 Oral Proficiency, Yunjung You

Open Access Dissertations

Lexical proficiency is strongly correlated with L2 productive language ability (Crossley, Salsbury, & McNamara, 2011; Laufer & Nation, 1995). While many studies have investigated the relationship between lexical proficiency and L2 writing ability, not many studies have been conducted in terms of spoken language. Also, few studies have focused on how non-native English speakers with different L1 backgrounds differently or similarly develop lexical proficiency in L2 speaking. Based on this background, the present study is conducted with three purposes: 1) to compare the effectiveness of measures of lexical proficiency in terms of their ability to predict the quality of L2 …

A Sociosemantic Examination Of Secondary English Teacher Written Feedback, Ryan Angus

Open Access Dissertations

The purpose of this study was to provide a functional linguistic based description of teacher writing comments in secondary ELA classrooms. Based within a case study methodology, this study used analytical tools from Systemic Functional Linguistics (SFL) and Legitimation Code Theory (LCT) in order to discover the various meanings that teachers make through their commenting practices. The findings of the study show that teacher comments focus on the content of the student writing, but also, significantly, help teachers to discursively realize various teacher identities. It was also found that teacher comments tended to either be concrete in their reference to …

Disentangling Fluency, Comprehensibility And Coherence: Toward A Better Understanding Of Oral Proficiency Profiles, Haiying Cao

Open Access Dissertations

This study is an empirical attempt to examine how removal of all possible disfluency markers can help disentangle proficiency components assessed by the Oral English Proficiency Test (OEPT) in order to help build empirical foundations for establishing OEPT profiles. Silent and filled pauses, false starts and repetitions were removed from 50 test recordings in WAVEPAD SOUND EDITOR. Five trained OEPT raters rated the original and edited speeches. Statistical analyses addressed three research questions: 1) do fluency, comprehensibility and coherence ratings significantly change after the disfluency manipulation; 2) do correlations between fluency, comprehensibility, coherence and coherence subcomponents change after the disfluency …

Associated Behavioral, Genetic, And Gene Expression Variation With Alternative Life History Tactics In Salmonid Fishes, Ashley Chin-Baarstad

Open Access Dissertations

Individual differences in behavior can have potential fitness consequences and often reflect underlying genetic variation. My research focuses on three objectives related to individual level variation: 1) evaluating the innate behavioral variation within and between individuals, families, and progeny of different life-history types across time; 2) testing for differences in gene expression within the brain associated with this behavioral variation; and 3) using genetic polymorphisms to test for associations with ecotype, as well as population structure, in polymorphic populations. First, we evaluated the variation in a suite of ecologically relevant behaviors across time in juvenile progeny produced from crosses within …

Integration Of Z-Depth In Compositing, Kayla Steckel

Open Access Theses

It is important for video compositors to be able to complete their jobs quickly and efficiently. One of the tasks they might encounter is to insert assets such as characters into a 3D rendered environment that has depth information embedded into the image sequence. Currently, a plug-in that facilitates this task (Depth Matte®) functions by looking at the depth information of the layer it's applied to and showing or hiding pixels of that layer. In this plug-in, the Z-Depth used is locked to the layer the plug-in is applied. This research focuses on comparing Depth Matte® to a custom-made plug-in …
