The present study aims at studying the surface morphology, crystallinity and optical emission property of Mg added ZnO grown by molecular beam epitaxy. Zn1-xMgxO epitaxial films were first grown at a fixed Zn flux of 1¡Ñ10-7 mbar and Mg flux of 4¡Ñ10-10 to 6.2¡Ñ10-9 mbar on sapphire substrates at 400 oC. The corresponding Mg content (x) is in a range of <0.01 to 0.17. Scanning electron microscopy observations indicated that the surface of the films are flat. The orientation relationship between the film and the substrate is: (0001)Zn1-xMgxO¡ü(0001)Al2O3©M[101 ¡Â0] Zn1-xMgxO¡ü[112 ¡Â0] Al2O3. The full width at half maximum (FWHM) of the (0002) reflection in rocking curve measurement is in a range of 3.83 o to 4.81 o. Photoluminescence results showed that the intensities of both the near band-gap emission and the deep level emission increases with increasing Mg content. The former has FWHM values of 0.16-0.21 eV. While the epitaxial films were grown at a high Zn flux of 5¡Ñ10-7 mbar and Mg flux of 2¡Ñ10-9 to 9.6¡Ñ10-9 mbar on sapphire and LiAlO2 substrates at 400 oC, the film surface are at high roughness. The FWHM of (0002) rocking curve is 4.43 o to 5.71 o for films grown on sapphire and is relatively larger of 6.88 o to 8.18 o for films grown on LiAlO2, respectively. These films possess a stronger near band-gap emission and a lower deep level emission as compared to the films grown at a low Zn flux. After annealed at 600 oC in oxygen or nitrogen, the FWHMs of the (0002) rocking curve for most of the epilayers decreased slightly. The photoluminescence results were rather distinct. For samples having low Mg content (x<0.05), the intensity of the near band-gap emission increases 50-200 ¢H after annealed in oxygen. The intensity of the near band-gap emission did not change but that of the deep level emission decreases ~50 ¢H for the film having x=0.16 after annealing in oxygen. The emission characteristics basically do not change after annealed in nitrogen.

Victors do not always write history. To date our knowledge of how the Pathet Lao seized power in Laos in 1975 has been based on accounts from those who witnessed events but who were not privy to the thinking and planning behind them. After the violent fall of Cambodia and Vietnam, the slow, relatively peaceful and seemingly dilatory takeover of power they observed did not equate with the Lao People’s Revolutionary Party’s assertion that its seizure of power was due to the “creative application of Marxism-Leninism to Lao conditions”. This work attempts to determine the accuracy of the Lao Party’s claim by using LPRP documents and written and verbal accounts, which reveal the strategic thinking and tactics behind the Lao Revolution. The piecing together of information drawn from many and varied sources that were directly involved, at last sheds some light on how a small, weak movement overthrew a government almost without violence. It also reveals that the LPRP carefully and deliberately planned and executed the peaceful formation of the Lao People’s Democratic Republic in December 1975 in a revolution that was unprecedented in the history of Marxist-Leninist revolutions.

This dissertation is an investigation of serial verb constructions in Lao (Tai-Kadai, SVO) and the events that they encode. Serial verb constructions (SVCs), structures where multiple verbs appear in a single clause, raise several important questions for syntactic theory. One issue is how the verbs are related; proposals involving coordination (Payne 1985), subordination (Collins 1997), and adjunction (Hale 1991; Muansuwan 2002) have all been made, while others have made a case for unorthodox double-headed structures (Baker & Stewart 2002; Baker 1989). Additionally, the argument sharing seen in SVCs is seemingly incompatible with proposed constraints on theta-role assignment, such as the Theta-Criterion (Chomsky 1981) or the Biuniqueness Condition (Bresnan 1980). In this thesis I describe new data from the Lao language focusing on two subtypes of SVC that Stewart (1998) calls consequential SVCs (CSVCs) and resultative SVCs (RSVCs). I propose a generative analysis of these structures where an event head licenses a complex VP containing multiple verbs where the object is thematically related to the complex VP rather than the individual predicates. Evidence for the event head comes from a modified version of the explicit segmentation task (Zacks et al. 2001). During the experiment, participants were instructed to divide video clips into events. When participants saw a CSVC before the video, they divided the action sequence depicted by the CSVC into fewer events than when participants saw a coordinated construction before the video. These results suggest that seeing the SVC prompted the participants to group the target sequence of events in the videos together as a larger macro-event, supporting the claim that SVCs encode a single event (contra Foley 2010). These data also support the proposal that events are conceptualized at the clausal level, rather than at the verbal level, which is in line with proposals from Evans (2010), Jackendoff (1991), and Pustejovsky (1991).

The microbial diversity of branches of Kaoping River at Lao-Nong Basin with altitudes from 100-2204m and Nantzuhien Basin with altitudes from 100-654m were studied. We used combining methods of bacterial, chemical and biotechnological to explore microbial diversity at the two basins to provide a reference for the environmental ecology of Kapoing River. It is the foundation for practicable environmental care. The results show the following: (1) The temperature in Tianchin at Lao-Nong Basin was lower(16.3¢J) than the rest of sampling sites(22-28¢J). (2) The temperature in Minsheng at Nantzuhsien Basin is lower(21.5¢J)than the of sampling sites(24-33¢J); other factors such as pH value, total organic carbon, and total organic nitrogen, varied according to different locations. In the microbacterial composition quantitatively, among all microorganisms, the bacteria content was the highest. Each gram of soil contain about 106~109 CFU at Lao-Nong Basin and 105~109 CFU at Nantzuhsien Basin, where as others such as the contents of actinomycetes and fungi were lower. Using 16s rDNA DGGE (denaturing gradient gel electrophoresis)analysis, the soil bacterial community composition at the two basin districts had discoverd that the microbial diversites at Nantzuhsine Basin were more abundant than those at Lao-Nong Basin. In regard to seasonal changes, our data agreed with traditional data. In the warm season, the microbial content is higher, and the community composition is also more abundant. The weather change in a short time period, such as a rainstorm and a quick shift of temperature seriously affected the number of bacteria. When the rain pours steadily down, it caused some degree of drop in bacteria number. However, when the rain stop, the microbacterial content and community composition gradually retured to original forms.

Home - the universally understood and desired state of being that is existing naturally, harmoniously, familiar, and whole. What does it mean to leave home and to seek refuge? And how do we find home again? Throughout history and today, communities across the globe have either suffered in or been plagued with a refugee crisis in some form. Laos is the most bombed country per capita in history. During the American Secret War on Laos, 270 million tons of cluster bombs were dropped on Laos from 1964-1973: equivalent to a planeload of bombs every 8 minutes, 24 hours per day, for 9 years. Today, over 265,000 Lao Americans live in the United States with a majority of them arriving as refugees in the 1980s as a result of the Secret War. Lao Americans forced from their homes have since found refuge but what does it look like for them to come home? Understanding home as not only defined as a physical geospatial location, what creates the physiological sense being at home in one's body and one's mind? These are the questions underpinning this thesis. They necessitate an understanding of psychology, sociology, and neurology in a way that has traditionally not been a framework of architectural education and design process thinking. As the broader mental health crisis and concern for well-being continues to dominate societal struggles, architecture and design are called upon to evolve their methodologies. Making Space: Refuge to Home presents a design methodology that focuses on cultivating an informed and empathic client relationship in order to drive intentional design choices based on desired physiological outcomes. In doing so, this thesis offers an approach of how to navigate the complexities of place, home, safety, and identity in order to make space that shifts from providing refuge and safety, to being home and whole. By utilizing participatory story-telling, psycho-social outcome identification, and empathic imagination, this thesis develops a trauma-informed and well-being centric design approach for cultivating resilience and making space to come home. This methodological rigor is applied specifically to the Lao American community and their experience of forced resettlement and intergenerational trauma. Making Space: Refuge to Home challenges traditional architectural approaches that often lean on cultural appropriation, iconographic motifs, or traditional programmatic understandings of what a cultural center is and instead, crafts a new design language. The result is a design approach that places the lived emotional and physiological experience of the user group first. The result is an attempt at a more authentic and complex understanding of home that straddles a multiplicity of cultures and lived realities. / Master of Architecture / Home - the universally understood and desired state of being that is existing naturally, harmoniously, familiar, and whole. What does it mean to leave home and to seek refuge? And how do we find home again? Throughout history and presently, communities across the globe have either suffered in or been plagued with a refugee crisis. Laos is the most bombed country per capita in history.

Understanding home as not only defined as a physical geospatial location, what creates the physiological sense being at home in one's body and one's mind? These are the questions underpinning this thesis. The direct connection of the built environment and individual well-being has only become more apparent in the past two years as a widespread societal awakening towards systemic issues around public health have been illuminated during the global pandemic. As the mental health crisis and concern for well-being continues to dominate societal struggles, Making Space: Refuge to Home presents a design methodology that focuses on using psychology, sociology, and neurology to inform an empathic client relationship that is better equipped to drive intentional design choices. In doing so, this thesis offers a trauma-informed and well-being centric design approach of how to navigate the complexities of place, home, safety, and identity in order to make space that transforms from simply offering refuge to being home. This method is applied specifically to a study of the Lao American community and their lived experience of forced resettlement and intergenerational trauma. Although the thesis focuses on the Lao American community, Making Space: Refuge to Home, speaks to all communities and individuals navigating multiple identities and cultures, seeking wholeness - seeking home.

L’intention de ce travail est de réfléchir sur les ponts possibles entre Maurice Merleau-Ponty, Maurice Blanchot et Lao Tseu concernant des rapports complexes que la nature entretient avec le langage, notamment sur la question des fondements de l’acte de nomination. Il ne s’agit pas de construire une étude comparatiste entre la philosophie occidentale et la philosophie extrême-orientale, mais de travailler les concepts de nature et de langage pour les confronter et voir comment des auteurs comme Merleau-Ponty, Blanchot et Lao Tseu font bouger les lignes quand on les fait interagir sur des notions identiques avec des contextes et des cultures complètement étrangères : Merleau-Ponty étranger à « l’informulé dans le connu du mot », Blanchot étranger à la Prose du monde comme fondation de la vérité, et Lao Tseu étranger par nature à l’un et à l’autre tout en étant familier de cette même communauté de pensée. / The purpose for this research focuses on issues involving the complex relations between the nature and languages as well as the common grounds for the concepts of “naming” among three scholars: Merleau-Ponty,Maurice Blanchot and laozi. The research will delve into the relation between the nature and language and have discussions on the relevance for the issue among three scholars rather than put emphasis on the comparative research of the issue among them. Technically, we will have more discussions with regards to how the three scholars manage to discard traditional meanings and thoughts over the issue while making their own interpretations based on varied contexts and reflecting on philosophical theories opposite the theories they proposed according to their individual cultural backgrounds: the unknown semantics of the sentence for Merleau-Ponty( evey word read is given its own semantics), Blanchot feel unfamiliar to the basic concept for allwords and sentences across the world is the very truth. While the previous theories mentioned are foreign to Laozi.
