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
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 …

Role Conflict, Uncertainty In Illness, And Illness-Related Communication Avoidance: College Students Facing Familial Chronic Illness, Meghana Suchak
Open Access Dissertations
The focus of the current study was on examining possible differences in college students' adjustment based on residency status (i.e., international Asian vs. domestic students) and illness status (i.e., having a family member with a chronic illness vs. not having a family member with a chronic illness). The study also examined the associations between overall college student adjustment and the family and illness-related factors of role conflict, uncertainty in illness, and illness-related communication avoidance for students will a chronically ill family member. 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
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 Gi/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 …
A Sociosemantic Examination Of Secondary English Teacher Written Feedback, Ryan Angus
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
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
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 …
The Role Of Adiponectin And The Adipocyte In Energy Metabolism And Inflammation, Sheila Kay Jacobi
The Role Of Adiponectin And The Adipocyte In Energy Metabolism And Inflammation, Sheila Kay Jacobi
Open Access Dissertations
A series of experiments were conducted to characterize the autocrine role of adiponectin in modulating fatty acid metabolism and inflammation in the pig. In the first study, we cloned and sequenced the porcine adiponectin open reading frame and evaluated the regulation of adiponectin, in vitro and in vivo. The porcine sequence shares approximately 88, 86, 85 and 83% homology with the dog, human, cow and mouse adiponectin, respectively, and 79–83% similarity with dog, human, cow and mouse proteins at the amino acid level, based on the translated porcine sequence and GenBank submissions for the other species. Analysis of serum from …

Culturally Responsive Engineering Education: A Case Study Of A Pre-College Introductory Engineering Course At Tibetan Children's Village School Of Selakui, Marisol Mercado Santiago
Open Access Dissertations
Culturally responsive teaching has been argued to be effective in the education of Indigenous youth. 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 …
La Leche League, The Media, And The Nursing Mother: A Broader Perspective On Persona Theory, Erin F Doss
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
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
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 …

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 …
Relationships Between Lexical Proficiency And L2 Oral Proficiency, Yunjung You
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 …
White Racial Attitudes In The Age Of Obama, Ryan Jerome Lecount
White Racial Attitudes In The Age Of Obama, Ryan Jerome Lecount
Open Access Dissertations
What is the nature of White racial attitudes in the age of Obama? This dissertation project seeks to answer this question in three distinct ways. The first empirical chapter examines the role of economic insecurity and education on White racial attitudes. The second empirical chapter evaluates the relative importance of individual vs. contextual factors in shaping Whites' attitudes about race. The third empirical chapter seeks to evaluate the extent to which racial color-blindness (as opposed to other racial attitudes) motivates White opposition to race-targeted programs. Findings in empirical chapters one and two are conditional, while clear evidence is demonstrated that …
Human And Canine Personality Assessment Instruments To Predict Successful Adoptions With Shelter Dogs, Sheryl Lynn Walker
Human And Canine Personality Assessment Instruments To Predict Successful Adoptions With Shelter Dogs, Sheryl Lynn Walker
Open Access Dissertations
Animal shelters are often over-crowded with animals, and efforts to match potential adopters with shelter dogs, to improve the quality of adoptions, are increasing. However, a lack of evidence-based practices makes matching difficult. This research was conducted to investigate the role of dog and human personality, using questionnaire-based measurements, on adoption success in two Indiana shelters, Clinton County Humane Society and the Humane Society of Indianapolis. Ultimately, the aim of this project was to assess dog personality, human personality, and satisfaction, to evaluate adoption success in shelter dogs.^ The present thesis contains three studies exploring dog and human personality traits, …
