An analysis for promoting residential-scale solar photovoltaic (PV) in Bangkok, Thailand
(2015-12) Chaianong, Aksornchan; King, Carey Wayne, 1974; Pharino, Chanathip
Solar Photovoltaic (PV) has a significant potential for distributed energy in the urban environment of Bangkok, Thailand in order to decrease the country’s reliance on imported conventional energy and enhance the country’s energy security. This research analyzes the technical, economic and policy analysis of installing 3,000 MW (Thailand’s solar PV goal) of residential solar PV in Bangkok using System Advisor Model (SAM) and also compares each analysis to large-scale load (e.g. manufacturing). In technical analysis, the relationship of distributed solar energy and electric load from the grid is analyzed. While the residential load and peak solar irradiance are not correspondent for residential scale, generating electricity from 3,000 MW of solar PV can still decrease residential daily load consumption from the grid by 38 percent. On the other hand, the distributed of solar energy and large-scale load are well matched. As a result, the large-scale peak load can be reduced by 16.7 percent from 3,000 MW solar installation. Regarding to economic analysis, the levelized cost of energy of residential scale is higher than large scale. Without tariff, costs of solar electricity are higher than grid price. Therefore, it is necessary to introduce solar tariff to encourage people to install solar PV. Throughout solar project’s lifetime, with current Thailand’s solar incentives (Feed-in Tariff; FIT), solar project investments of both scales seem feasible from financial perspectives under Thai’s government cost assumptions. In addition, due to the increasing urbanization rate and typical land use of Bangkok, residential solar PV seems to be the better candidate. However, some technical and policy barriers remain, such as the lacks of skilled manpower, policy mix, and financing options as well as the inconsistence of governmental support. It is essential for Thai government to overcome these barriers in order to create sustainable growth of solar PV in the country.
Colistin for multidrug-resistant Acinetobacter baumannii from Thailand
(2010-08) Srisupha-Olarn, Warunee; Burgess, David S., doctor of pharmacy; Frei, Christopher R.
Multidrug-resistant (MDR) Acinetobacter baumannii have caused nosocomial infections worldwide. Nowadays, there are no effective regimens to treat MDR- A. baumannii. Therefore, this study’s objective was to find out an effective antimicrobial combination against MDR-A. baumannii. This project consisted of four parts. Part 1 was an in vitro antimicrobial susceptibility test of MDR-A. baumannii collected from Thailand. Minimum inhibitory concentrations (MICs) were performed according to the Clinical and Laboratory Standards Institute (CLSI) guidelines using a broth microdilution technique. This study found that colistin was the most active against MDR-A. baumannii (MIC50 0.5µg/mL, MIC90 1µg/mL). In addition, 77% of MBL -producing A. baumannii were reported using the MBL Etest strips. This prevalence was higher than previously reported. Part 2 was conducted to compare antimicrobial susceptibility profiles of pre- and post-colistin exposure A. baumannii isolates. After colistin exposure, A. baumannii isolates became resistant to colistin but more susceptible to cefepime, doxycycline, meropenem and rifampicin. These findings suggested the potential of a synergistic activity of colistin combinations. Part 3 was a time-kill study that compared activity of colistin alone and in combination against MDR-A. baumannii. Time-kill assays were performed using a standard inoculum. Colistin monotherapy was rapidly bactericidal against these isolates; however, regrowth occurred at 24 hrs. On the other hand, colistin in combination with cefepime, doxycycline, meropenem or rifampicin demonstrated synergy and maintained bactericidal activity over 24 hrs (100%). Part 4 was designed to optimize meropenem dosing regimens using a PK-PD model. Three MDR-A. baumannii with colistin MICs (0.5-1µg/mL) and meropenem MICs (32-128µg/mL) were tested. The antimicrobial regimens alone and in combination evaluated were: colistin 2.5mg/kg every 12 hrs, meropenem 3g and 6g continuously infused (CI) over 24 hrs. Colistin monotherapy was rapidly bactericidal but regrowth did occur. Both combinations express synergy (100%). Nevertheless, colistin and high dose meropenem (6g CI over 24 hrs) was bactericidal and prevented regrowth over 24 hrs. In conclusion, MBL-producing A. baumannii is more prevalent than previously thought and colistin combined with a high dose meropenem (6g/day) has good potential to overcome multidrug- and carbapenem-resistant A. baumannii. These findings should be further evaluated in animal models and clinical practices.
Electoral reforms and the transformation of party system : Thailand in comparative perspective
(2014-12) Huang, Kai-Ping; Moser, Robert G., 1966-; Lin, Tse-min
Most studies of electoral system effects tend to ignore the characteristics of parties in the causal chain. Yet, this dissertation argues that different party structures, when interacting with electoral systems, lead to different levels of party system fragmentation. In a weak party structure, elite action is the key to explaining the different outcomes: a permissive electoral system tends to inflate the number of parties because the rule poses an obstacle to elites’ electoral coordination. But this major obstacle is removed under a restrictive rule, which results in lower fragmentation. By contrast, the role of voters becomes active in a strong party structure; therefore, the effects of permissive and restrictive electoral systems become similar as both tend to bring down the number of parties through voters’ strategic behavior. This dissertation tests the theory on Thailand since the country has gone through three waves of electoral reform in which the electoral system has been changed between a permissive and a restrictive electoral rule. At the same time, the party structure has changed following the victory of the Thai Rak Thai Party in the 2001 election. The changing interactions of party structures and electoral systems provide a quasiexperimental setting conducive to inspecting the effects of the key factors on party system fragmentation while other confounding variables (social heterogeneity and viii political institutions) are held constant. This research design allows me to compare periods of time in different configurations of party system fragmentation. This dissertation applied multi-methods, including case study analysis, single-country multilevel quantitative analysis, and a large N, cross-national quantitative analysis, to reach the conclusions. Theoretically, the findings suggest that electoral system effects are contingent on party structures. Successful institutional engineering requires deep understanding of both formal rules and the political context of a particular country. In other words, one size cannot fit all, even for the same country at different times.

Looking elsewhere : migration, risk, and decision-making in rural Cambodia
(2012-12) Bylander, Maryann; Charrad, M. (Mounira); Roberts, Bryan R., 1939-
International labor migration has become an increasingly common livelihood strategy in rural Cambodia, in some villages becoming a defining and normative part of community life. This dissertation is an ethnographic study of one such rural community, where migration to Thailand has become a primary livelihood strategy over the past decade. Drawing on three years of fieldwork in Chanleas Dai, a commune (khum) in Northwest Cambodia, my research explores the complexities of the migration decision-making process, and the meanings of migration for rural households. This work is motivated by debates within the dialogues of migration and development, most of which seek to understand the potential for migration to promote development by focusing on the impacts of migration. My work departs from previous studies by focusing explicitly on decision-making, seeking to understand how and why families make developmentally important migration decisions. This is a critical area of inquiry, as the potential that migration has to promote or sustain development rests on a series of individual choices, for example who migrates, or how households invest remittances. Yet research tends to focus on the outcomes of these choices, neglecting a sufficient understanding of why they were made. In Chanleas Dai individuals are deeply ambivalent about migration, understanding it as both a constituent cause of insecurity and also the best path to security, mobility, and status. Whereas migration is perceived as low-risk and high-reward, village-based livelihoods are widely perceived as insufficient, impossible, or too financially risky to be meaningful. These perceptions are strongly linked to the recent history of environmental distress in the area. As a result, households often prioritize investment in further migrations, rather than using wages earned abroad for local investment or production. This is particularly true among youth, who see few potential worthwhile strategies to "make it" at home. Credit and agriculture programs theorized to curb migration, and/or promote local investment have not substantively challenged these perceptions. My conclusions discuss these findings in terms of their implications for the migration and development dialogues, definitions and understandings of development, and rural development policies both within and outside of Cambodia.

Understanding perspectives of teachers in Thailand towards information and communication technologies integration in the classroom
(2011-05) Wattanawaha, Benjaporn; Resta, Paul E.; Hughes, Joan; Liu, Min; Northcutt, Norvell; McCoy, Danny
The purpose of this research is to explore Thailand teachers’ perspectives towards the integration of ICTs into the teaching and learning process in order to better understand how teachers use technology for classroom instruction and their perceptions of the factors that influence their use of ICTs. The study applied Interactive Qualitative Analysis (IQA) approach to draw a systems thinking of teachers and to provide in-depth perspectives of teachers about their implementation of ICTs in the classroom. Eighteen computer teachers and twenty-two mathematics teachers participated in a focus group interview. Fifteen computer teachers and fourteen mathematics teachers were invited to participate in an individual interview. Results from the data analysis based on the IQA approach showed that teachers’ perspectives on their integration of ICTs encompassed several components including School management and administration, Content and curriculum, Teacher, Information and Communication Technologies (ICTs), Student, Environment, Time, and Parent or guardian. The results also revealed a systems thinking of teachers that showed the interrelationships of the affinities. The statistical analysis comparing the perceptions of two teachers groups showed that there was only one affinity, which was “Student”, found to be significantly different at the .049 level. This could be because of difference in teacher perceptions of students. For other affinities, the results showed that both groups of teachers did not perceive their work experiences in a significantly different way.
