The 1898 Reform Movement, Britain, and China: an examination of four British writers on British-Chinese relations 1895-1900
Cofell-Dwyer, Brittany Marie
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] This Master's project examines the factors, policies, and goals that four British authors- Edward Harper Parker, Holt Samuel Hallett, Robert Kennaway Douglas, and Richard Simpson Gundry- considered essential to British-Chinese relations between 1895 and 1900. This project explores Britain's late 1890s interactions with China, an understudied but important point in international relations and Chinese history. Furthermore, it argues that the 1898 Reform Movement and its consequences was the most significant event in 1895-1900 China. This stands in direct contrast to much scholarly work which emphasizes the importance of the Boxer Uprising. The project's author-based approach allows certain similarities and differences to emerge. It also offers connects a variety of topics- including China's domestic situation, the international pressures and participants in China, British policies and interests in China, the 1898 Reform, the 1898 coup d'état, and the situation in China by 1900- into a more comprehensive picture. Overall, all four authors wanted China to be preserved for the sake of British commerce and thus supported reforms in China.

Aging studies and sensing applications of protein-templated gold nanoclusters
Hofmann, Carrie M.
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Protein-templated gold nanoclusters (AuNCs) were synthesized using lysozyme VI (Lys VI), bovine serum albumin (BSA), and BSA nanoparticles (BSA NPs) as individual protein sources. Fluorescent quantum yields (Φf) were investigated over time, comparing the effect of different synthesis methods as well as the effect of storage temperature on the Φf. The study showed that the highest Φf were exhibited by BSA-stabilized AuNCs (BSA−AuNCs) prepared using microwave irradiation exhibited higher Φf (max. 13.33 ± 0.98%) stored at 4°C and Lys VI-stabilized AuNCs (Lys VI−AuNCs) (max. 17.44 ± 0.17%) that were conventionally synthesized. While AuNCs were successfully shown to be embedded in BSA NPs (BSA NPs−AuNCs) the Φf were found to be rather low (~2-3%) for both preparation routes. BSA−AuNCs prepared by microwave irradiation were then used for the ratiometric sensing of metal ions in solution and sol-gel thin films. The systems showed high selectivity towards Hg[superscript 2+] with nearly complete fluorescence quenching of the Au25 peak upon the addition of 25 μM Hg[superscript 2+]. Next, BSA-AuNCs were immobilized on cellulose filter paper for the visual detection of metal ions, displaying selectivity towards Hg[superscript 2+], Cu[superscript 2+], and Ni[superscript 2+] with Hg[superscript 2+] showing the most visible change in fluorescence upon the smallest addition of ions.

Alcohol cues, approach bias, and inhibitory control : applying a dual process model to alcohol sensitivity
Fleming, Kimberly A.
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Low sensitivity to the acute effects of alcohol, or needing a relatively large amount to feel alcohol's effects, is a risk factor for developing AUDs and related problems. Dual process models of addiction posit that decisions to engage in substance use are governed by the relative strength of two modes of information processing: an impulsive, approach-motivational process, and a reflective, cognitive control process regulating approach tendencies. The current study had two main aims: (1) to test for differences in alcohol approach bias among high- and low-sensitivity drinkers, and (2) to investigate the neural and behavioral consequences of this bias for inhibitory control in the presence of alcohol cues. Eighty-five participants varying in alcohol sensitivity completed an Alcohol-Approach Avoidance Task and a Cued Go/No-Go Task while ERPs were recorded. Low sensitivity individuals showed automatic approach tendencies towards alcohol cues in the Alcohol-AAT and additionally, a behavioral approach bias in the Cued Go/No-Go Task by responding faster to alcohol targets than nonalcohol targets. These individuals experienced behavioral inhibition deficits during alcohol-cued trials that required the withholding of a prepotent response. Analyses of the ERP data indicated that alcohol-cued trials in which a prepotent behavioral response must be suppressed elicited increased N200 and P300 amplitude among LS individuals that was not seen on nonalcohol-cued trials. Together, these data indicate that alcohol cues elicit an approach bias among LS individuals, translating into greater difficulty inhibiting behavioral responses in the presence of such cues, a pattern generally supportive of dual process models of substance use.

Analysis of dual-phase ejector performance
Elmore, Emily Ferner
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] An analytical model is proposed to extend the single-phase model for predicting ejector performance, particularly pressure recovery and efficiency, to entrained fluids of a liquid/gas mixture. Liquid ejector performance is studied experimentally when the entrained fluid is both a single-phase liquid (water) and a dual-phase liquid/gas mixture (water/air). The experimental program consists of 27 tests utilizing a clear ejector representative of those employed in aerospace applications for measurement of pressure profile and specially designed for visualization of bubble and flow patterns. Motive fluid is supplied from 4.5 to 18 GPM and available fluid head is supplied from 3 to 9 inches of water above the secondary inlet. The analytical model extends previous models that describe single-phase performance from mass and energy conservation. The empirical loss coefficients are replaced by analytical equations accounting for the geometry of and flow conditions within the individual ejector components. The results show consistently better agreement with the experimental data than those delivered by existing models, reducing the root mean square error of the pressure recovery prediction to less than 10% of its former value.
