A Comparative Study Of Young Children's Risk-Taking Behavior In China And U.S.: A Multiple-Group Path Analysis, Jun Hao
Electronic Theses and Dissertations Archive
Risk-taking is inevitable, uncertain, and essential in early childhood. Researchers suggest four important factors that influence young childrens risk-taking behavior, namely, childrens temperament of sensation seeking, parents perception of risk, parental supervision, and society. However, there has been little effort to examine how the four factors collectively impact young childrens risk-taking behavior. The purpose of this study was to understand (1) what role the three factors (childrens sensation seeking, parents risk perception, and parental supervision) play in childrens risk-taking behavior; and (2) how their relations vary by society.

Towards Zero Response Time Modified Sensors: Synthesis, Characterization, And Deposition Of Edot-Decorated Porous Nanocapsules And Simulations Of Mass Transport In Polymeric Films On Sensor Surfaces, Bradley Hambly
Electronic Theses and Dissertations Archive
The response time of chemical sensors is a critical performance characteristic that may determine their utility in a variety of applications. The rate-determining step, which controls the response time, can be either mass transport or the rate of a chemical/electrochemical reaction. To optimize the response of membrane-based sensors, we developed voltammetric methods for the determination of diffusion coefficients in polymeric membranes and demonstrated the influence of water and ion transport on the short- and long-term behavior of solid contact ion-selective electrodes (SC-ISEs). SC-ISEs are multi-layer systems with a conductive polymer (CP) film sandwiched between an ion-selective membrane and a base …

Inorganic Materials For Local Drug Delivery, Michael Anthony Harris
Electronic Theses and Dissertations Archive
Orthopedic infections, including periprosthetic joint infections and osteomyelitis, are debilitating complications that greatly increase mortality rates and expenditure of healthcare resources. Treatment protocols include surgical debridement of infected tissue, removal of any foreign implants, and several weeks of systemic antibiotic therapy, yet recurrence rates remain high. Local antibiotic delivery systems augment traditional therapy techniques by increasing antibiotic concentrations at the site of infection to levels that are unachievable by IV or oral delivery, thereby improving bacterial clearance rates. Current clinical products are commonly prepared at the surgeons direction, with only limited data and anecdotal reports guiding antibiotic choice and loading. …

One Essay On Market Microstructure And Two Essays On Corporate Finance And Financial Institutions, Jianning Huang
Electronic Theses and Dissertations Archive
This dissertation research comprises one essay on market microstructure and two essays on corporate finance and financial institutions. In the first essay, I examine the effects of a speed bump on market quality and exchange competition. After a long period of facilitating faster trading, exchanges are now trying to slow down trading with speed bumps. I study how this market-design innovation affects traders reaction times, the market quality of stocks, and the operators of competing exchanges. Post speed bump, I find slower reaction times to order book events and reduced order detection and back-running. Reduction in quote-to-trade ratio and flickering …

Yoknapatawpha Railroad: Trains And Mobility In The Novels Of William Faulkner, James Christopher O'Brien
Yoknapatawpha Railroad: Trains And Mobility In The Novels Of William Faulkner, James Christopher O'Brien
Electronic Theses and Dissertations Archive
Though considered one of the foremost of 20th-Century American modernists, many critics accuse William Faulkner of being obsessed with some idyllic southern past. In contrast, my study, utilizing the burgeoning field of mobility studies, focuses on the trains featured within his novels to counter this accusation. As I discuss, Faulkner does indeed question notions of modern progress wrought from industrialization as well as technological advancements, though he never offers blanket condemnations of them. In contrast, his depictions of railroad mobility reveal an attitude of active participation in modernity rather than cantankerous retreat. In my opening chapter, I begin by explaining …

Administrators' Benevolent And Corrective Humor And Suspensions Of African American School Age Females, Roslyn E. Bacon
Electronic Theses and Dissertations Archive
African American female students suspension rates are rising and outpacing those of all categories of students, including African American males. This is due, in part, to an administrators over-reliance on zero-tolerance disciplinary policies, as well as a teachers negative perception of African American female students. Soaring rates of suspension contribute to school disengagement, high dropout rates, and a formidable risk of involvement in the school to prison pipeline. In addition to the toll these risks take on human lives, society loses the benefit of human productivity, taxable wages, and stable, thriving communities. As attention to the rising rate of suspension …
