Design Method of Cold-Formed Steel Framed Shear Wall Sheathed by Structural Concrete Panel

Description: The objective of this research is developing a new method of design for cold-formed steel framed shear wall sheathed by ¾" thick USG structural panel concrete subfloor using a predictive analytical model and comparing the results obtained from the model with those achieved from real testing to verify the analytical model and predicted lateral load-carrying capacity resulted from that. Moreover, investigating the impact of various screw spacings on shear wall design parameter such as ultimate st… more

Determining the Diagnostic Accuracy of and Interpretation Guidelines for the Complex Trauma Inventory (CTI)

Description: The work group in charge of editing the trauma disorders in the upcoming edition of the International Classification of Diseases (ICD-11) made several changes to the trauma criteria. Specifically, they simplified the criteria for posttraumatic stress disorder (PTSD) and added a new trauma disorder called complex PTSD (CPTSD). To assess the new and newly defined trauma disorders, Litvin, Kaminski and Riggs developed a self-report trauma measure called the Complex Trauma Inventory (CTI). Although… more

Development of an Optical Carbon Dioxide Sensor and Modeling of Metal-Metal Interactions for Sensor Applications

Description: An investigation of luminescent sensing has been presented. Neutral Red, a common pH luminescent sensor, was shown to be an effective carbon dioxide sensor for the first time. Sensing experiments were performed both through fluorometric and fluorescent microscopy studies, giving rise to the possibility of carbon dioxide sensing for biological applications. Neutral Red was benchmarked against the well-established carbon dioxide sensor Pyranine (8-hydroxypyrene-1,3,6-trisulfonic acid trisodium sa… more

Effects of Customer's Evaluation about Instagram Attributes towards Purchase Intentions for Small Apparel Retailers: Application of Social Capital Theory

Description: Small apparel retailers face extreme competition with larger retailers. Large retailers have the upper hand in resources to stay updated with various trends, specifically social media. Social media has lowered the barriers to enter the retail industry. However, once these small retailers enter, half of them fail because they don't attract and retain customers. Small-medium enterprises (SMEs) greatly impact the economy, so it is important to study various facets of their business to increase per… more

An Empirical Investigation into the Value of Credit Lines

Description: Access to adequate liquidity to finance future investments is an essential element of financial management. The two main questions that this dissertation attempts to answer are (i) what is the net valuation effect of LoC? and (ii) if LoC create value, what are the sources of this value? To answer these questions, I constructed a sample of 85,232 firm-years spanning from 1993 to 2016, with credit line data obtained from Capital IQ and Bloomberg. I investigated the valuation effects of LoC with a… more

Ensemble Singing in the Bel Canto Salon Repertory: A Pedagogical Reconsideration

Description: Vocal duets have had a long history in the Western classical music tradition. Their use as a teaching resource can be traced back to the Renaissance, where duets were used for the development of singing, performance, and musicianship. In the late 19th and all of the 20th centuries, this pathway of vocal pedagogy has markedly declined. This study proposes a reintroduction of this methodology of teaching, asserting that it provides the collegiate vocal student with maximum opportunity for growth … more

Event Sequence Identification and Deep Learning Classification for Anomaly Detection and Predication on High-Performance Computing Systems

Description: High-performance computing (HPC) systems continue growing in both scale and complexity. These large-scale, heterogeneous systems generate tens of millions of log messages every day. Effective log analysis for understanding system behaviors and identifying system anomalies and failures is highly challenging. Existing log analysis approaches use line-by-line message processing. They are not effective for discovering subtle behavior patterns and their transitions, and thus may overlook some critic… more

Examining the Relationship between Bullying Experiences, Parental Partner Violence, and Partner Violence in Young Adulthood

Description: The current study used secondary analysis of existing data to examine associations between bullying experiences, parental partner violence, and partner violence in young adulthood. We hypothesized that bullying in adolescence would be associated with witnessing parental IPV in adolescence and IPV in young adulthood. We believed that deficits in social information processing, particularly hostile attribution biases, would be associated with adolescent bullying. Lastly, we believed that decenteri… more

An Exploration of the Changing Role of Principal Supervisors

Description: Existing literature provides newly identified responsibilities of the principal supervisor but lacks in information about how districts should strategically spearhead the process of initiating, implementing, and managing the changes to the role of the supervisor. In this study, I examined the behaviors and actions of one school district's executive-level leaders as they shifted the position of the principal supervisor. Findings could contribute to a new area of research in how district leader… more

Exploring Caffeyl-Lignin Biosynthesis in Cleome hassleriana and Polymerization of Caffeyl Alcohol in Arabidopsis thaliana

Description: C-lignin (caffeyl-lignin) is a novel linear lignin polymer found in the seed coats of several non-crop plants, notably Vanilla planifolia (Vanilla), Jatropha Curcas (Jatropha), and Cleome hassleriana (Cleome). C-lignin has several advantages over normal G/S-lignin, found in the majority of lignocellulosic biomass, for valorization in the context of bioprocessing: less cross-linking to cell wall polysaccharides (less recalcitrant biomass), ordered linkages between monomers (homogeneous polymer),… more

Exploring Predictors of Self-Forgiveness

Description: Self-forgiveness is a growing sub-field of the broader study of forgiveness, and initial research has linked self-forgiveness to positive mental and physical health outcomes. However, the extant literature on self-forgiveness is in its infancy, and there is a need for further research to understand the predictors of self-forgiveness and the clinical implications that might follow. The current study aimed to build on the extant literature by exploring two sets of predictors of self-forgiveness: … more

Exploring Psychosocial Correlates of Disordered Eating among Male Collegiate Athletes

Description: In research on disordered eating in female collegiate athletes, psychosocial correlates including elevated scores on measures of body image concerns, weight pressures, sociocultural internalization, and mood state were found significantly more often in either the eating disorder or symptomatic group as opposed to the asymptomatic group. Unique or nuanced pressures exist for male athletes as well, specifically a different ideal for body image, often described by a drive for muscularity. I examin… more

Famine Fighters: American Veterans, the American Relief Administration, and the 1921 Russian Famine

Description: This study argues that the American Relief Administration (ARA) operationally and culturally was defined by the character and experiences of First World War American military veterans. The historiography of the American Relief Administration in the last half-century has painted the ARA as a purely civilian organization greatly detached from the military sphere. By examining the military veterans of the ARA scholars can more accurately assess the image of the ARA, including what motivated their … more

Fatigue and Inhibitory Control: A Test of Key Implications of an Emerging Analysis of Behavioral Restraint Intensity

Description: Agtarap, Wright, Mlynski, Hammad, and Blackledge took an initial step in providing support for the predictive validity of a new conceptual analysis concerned with behavioral restraint - defined as active resistance against a behavioral impulse or urge. The current study was designed to partially replicate and extend findings from their study, employing a common film clip protocol and a procedure for inducing low- and high levels of fatigue. Analyses indicated that key cardiovascular (CV) resp… more
