Performance Evaluations Of Latex-Modified And Silica Fume Modified Concrete Overlays For Bridge Decks, Sathish Kumar Raju Konduru
Performance Evaluations Of Latex-Modified And Silica Fume Modified Concrete Overlays For Bridge Decks, Sathish Kumar Raju Konduru
Graduate Theses, Dissertations, and Problem Reports (ETD)
Most of the concrete bridge decks in the cold regions undergo severe reinforcement corrosion due to the transport of chloride ions within the concrete by application of deicing salts on bridge decks in the winter. As a result, protective concrete overlays of about 2-inch thickness are applied on bridge decks. Concrete overlays provide: (1) protection against heavy traffic and the further infiltration of the chloride ions; (2) skid resistance surface; and (3) uniform appearance to extend the service life of bridge decks. Despite these advantages, concrete overlays undergo premature delaminations, edge curling, and corner lifting due to expansion/shrinkage of concrete, …

Choice Between Schedules Of Reinforcement With And Without Response-Pacing Requirements, Leigh Schrimpf
Graduate Theses, Dissertations, and Problem Reports (ETD)
Differential-reinforcement-of-low-rate (DRL) and differential-reinforcement-of-high-rate (DRH) schedules specify a certain pace of responding eligible for reinforcement. The present study assessed the value of a paced schedule of reinforcement using a concurrent-chains schedule. Pigeon's pecks on the left and right initial-link keys led to one of two terminal-link VI 60-s schedules, programmed on the center key. Completion of a terminal-link schedule always led to access to grain. The value of a terminal-link schedule was measured by the initial-link choice proportions. In the baseline, pecks on either initial-link key produced access to one of two unpaced terminal-link schedules every 60 s, on average. …
The Role Of Emotional Intelligence On Coach-Athlete Relationships And Motivational Climate, Eric E. Steege
The Role Of Emotional Intelligence On Coach-Athlete Relationships And Motivational Climate, Eric E. Steege
Graduate Theses, Dissertations, and Problem Reports (ETD)
Research has revealed that Emotional Intelligence is linked to improved conflict resolution, enhanced social attachments and mental health, and the ability to create a collective set of goals that motivate others (Pau & Croucher, 2003). The recent surge of research assessing the role EI may play in leadership effectiveness, motivation, and social attachments within non-sport domains overlaps with similar research within sport that assesses the influence of emotion on coaching effectiveness (Frijda & Mesquita, 1994; Mageau & Vallerand, 2003). Thus, the purpose of this investigation was to examine if higher EI coached athletes (N=34) varied compared to lower EI coached …

Heavenly Genes: Eugenics And The New Woman In Fin De Siecle England., Jane V. Rago
Heavenly Genes: Eugenics And The New Woman In Fin De Siecle England., Jane V. Rago
Graduate Theses, Dissertations, and Problem Reports (ETD)
In 1886 the Contagious Diseases Acts were repealed after a long sixteen year fight, led by social reformers and what would later come to be known as the first wave of feminism. Western feminism was born and bred in large part out of the debates sparked by the Contagious Diseases Acts, debates that opened up into the appeal for women to be granted full citizenship through the right to vote, to own property after marriage, and the right to education and employment outside the home. The crux of this argument was grounded in a critique of mid-Victorian ideology of separate …
Parent-Child Interaction Therapy: The Effects Of Parental Attention Components On Children's Verbalizations And Attending-To-Task Behaviors., Ashley B. Tempel
Parent-Child Interaction Therapy: The Effects Of Parental Attention Components On Children's Verbalizations And Attending-To-Task Behaviors., Ashley B. Tempel
Graduate Theses, Dissertations, and Problem Reports (ETD)
Various evidence-based behavioral parent training programs are theoretically designed to target parenting skills that enhance parent-child interactions. Many similarities exist across the empirically-supported interventions, however programs also include unique components (e.g., use of reflections in Parent-Child Interaction Therapy). Empirical examination of individual components is necessary to inform components that promote or deter intervention effectiveness and efficiency. An empirically established association among language delays, behavior difficulties, and poor longitudinal outcomes further supports a need for identification of facilitative components. Currently, examinations of individual components have largely targeted the effects of praise and time-out. Despite clinical assertions that additional components serve important …

An Introduction To The Solo Piano Works Of Three Latin American Composers: Miguel Del Aguila, Tania Leon, And Juan Maria Solare., Yew Choong Cheong
Graduate Theses, Dissertations, and Problem Reports (ETD)
The American musical scene, since 1950, has been complex and varied, and the musical developments in Latin America have been no exception: the composers, both the native-born and the emigre, have written and continue to write in every known style, embracing such diverse musical influences as European Art Music, vernacular music, and non-Western world music. The musical culture of Latin America is extraordinarily rich, with its historical development that can be traced back to the pre-Columbian era (before 1500). The music of three contemporary Latin American composers—Miguel del Aguila, Tania Leon, and Juan Maria Solare—reflect a postmodern aesthetic in that …
Consolidation Of Parental Monitoring Variables And Scales: Preliminary Evidence For Construct Validity, Ryan J. Anderson
Consolidation Of Parental Monitoring Variables And Scales: Preliminary Evidence For Construct Validity, Ryan J. Anderson
Graduate Theses, Dissertations, and Problem Reports (ETD)
The aim of the present study was to improve definitions of parental monitoring constructs by reducing the domain of content from which researchers have sampled in previous investigations. For example, between the years of 1991 and 2007 researchers developed at least 49 different parental monitoring scales comprised of a total of 310 questions or items. Visual inspection of these scales as well as thorough review of the parental monitoring literature suggested that researchers primarily were interested in assessing five domains of content (the sum of which is described as parental monitoring). These five domains of content are (1) adolescent perceptions …

Effective Maxillary Protraction: Hyrax Expansion Appliance Vs. Double-Hinged Expansion Appliance, Thuy B. Do-Delatour
Graduate Theses, Dissertations, and Problem Reports (ETD)
Patients with a skeletal Class III malocclusion may have one of the following conditions: midface deficiency and/or mandibular hypertrophy/prognathism. If modification of the skeletal Class III growth pattern is not effectively accomplished at an early age via maxillary protraction, then orthognathic surgery would be required to help correct the skeletal Class III malocclusion. Some of the more serious risks associated with orthognathic surgery include parasthesia, bone and tissue necrosis, and possibly death. However, if one is able to effectively protract the maxilla, the need for anterior-posterior correction of the maxilla via orthognathic surgery will be minimized if not eliminated.;The purpose …

High Temperature Studies Of Thin Film Aluminum Nitride And Piezoelectric Characterization Of Mesa Structures, Richard Farrell
Graduate Theses, Dissertations, and Problem Reports (ETD)
Aluminum Nitride (AlN) is a group III--V compound that grows in a hexagonal wurtzite crystal structure and is a popular material for microelectromechanical systems (MEMS) due in part to its piezoelectricity, inertness and tolerance to high temperatures. High temperature stability is an essential characteristic for numerous MEMS applications, so one of the goals of this work is to determine how the material properties of AlN are affected by exposure to high temperatures and harsh environments. 3D AlN devices are also investigated to determine the effect of electric field isolation on the piezoelectric response of AlN.;A Rapid Thermal Annealing (RTA) system …
The Effects Of Aquaculture Production Noise On The Growth, Hearing, Disease Resistance, And Survival Of Rainbow Trout (Oncorhynchus Mykiss) And Methods For Minimizing Noise In Fiberglass Aquaculture Tanks, John W. Davidson Iii
Graduate Theses, Dissertations, and Problem Reports (ETD)
Intensive aquaculture systems, particularly recirculating systems, often require noise producing equipment such as pumps, blowers, and filters that inadvertently increase sound levels within the culture environment. These systems are often very effective at culturing healthy, fast growing fish; however, the potential impacts of underwater noise on fish within intensive aquaculture systems have not been evaluated. Limited research suggests that subjecting fish to noise could result in impairment of the auditory system, reduced growth rates, and increased stress. The studies presented within this manuscript were conducted to gain a better understanding of aquaculture production noise and its potential impacts on rainbow …

Local Agency Traffic Sign Retroreflectivity Case Study And Model Of Observed Traffic Sign Light Intensity, Mark L. Franz
Graduate Theses, Dissertations, and Problem Reports (ETD)
Despite the lower traffic volumes, nearly 50 percent of America's fatal motor vehicle crashes occur at night. A contributing factor to the higher fatality rate at night is the reduced ability of motorists to be informed by visual cues. Therefore, motorists often rely on traffic control devices (TCD) under dark conditions for information, warnings, and guidance. This study focused on the visibility of traffic signs under dark conditions.;The new MUTCD standards on traffic sign retroreflectivity have been promulgated to improve nighttime driving safety on all roads open to public travel. This includes roads under the jurisdiction of local road agencies …
