In Qing Dynasty, Chang’s family was one of the most famous merchants of the Shanxi ancient business. Chang’s Manor, which has a history of more than 200 years, stays as the most awarded civil building assembly among all the Shanxi compounds by its elaborate sculptures, wooden decorated archways, brick sculpted walls and many other art forms. Since 2001, Chang’s Manor has been commercialized for tourism purpose. Many “interesting stories” have been made up while lots of facts which are the real “people’s history” were left out and may be lost forever. This is also a common problem within many heritages which have been transformed into tourist attractions in China. And this arouses my research interests. In this dissertation, I would like to seek and tell the “true stories” from 1949 to 2001 in accordance with my conversation with the original habitants who have had real life experience of the original places. Surely, I will identify the real social value of Chang’s Manor through the interpretation of the true stories from local people. / published_or_final_version / Conservation / Master / Master of Science in Conservation

With the high populations of the Qiang people (羌) living in Maoxian County (茂縣), Wenchuan (汶川), Li county (理縣)& Beichuan County (北川); the geomorphology and natural ecological environment were serious damaged in "5.12" Wenchuan earthquake. Many of the villages were destroyed or severely damaged; it brought a huge casualties and losses to the Qiang cultural. Natural ecosystems through natural and artificial repair after a certain period can make basic recovery. As a historical legacy of the Qiang village, due to the seismic requirement and the changed of modern life living standard, it is hard to rebuild the entire intangible cultural heritage. It is a very complex and important to focus on the content of the cultural reconstruction of Qiang’s community. Among most of the cultural rebuilt projects were most likely set up a new cultural museum or a cultural center to conserve the minority groups tangible heritage. This is a very passive way to display the Qiang’s traditional heritage. As time changes and technology advancement, Qiang people are not living isolated to the outer world. In another hand, they share and receive information from other ethnic such as Han and Tibetan. The county street market is the best place for them to interact with other group of people besides selling goods for living improvement. This thesis confers Qiang people’s traditional culture heritage and their community evolution to redevelop a new streetscape for local market and public leisure purpose. Taking the chance of develop from earthquake, up to 50% of the street side building can be demolished and partially refurnish. With landscape planning and design, this street will be reset and provide a enhance environment as a multi-cultural sharing platform. / published_or_final_version / Architecture / Master / Master of Landscape Architecture

The Hekou Group in the Kangdian region, SW Yangtze Block is a metavolcanic-metasedimentary succession hosting the giant Lala Fe-Cu-(Mo, REE) deposit. Mafic volcanic rocks of the Hekou Group and nearby gabbroic intrusions have identical zircon U-Pb ages of ~1700 Ma. The sedimentary and mafic rocks are suggested to have formed in an intra-continental rift, similar to those of the North Australian Craton. Such a similarity suggests that the Yangtze Block was likely linked with the North Australian Craton in the Columbia supercontinent during late Paleoproterozoic. Overlying the Hekou Group is a thick sedimentary sequence of the Julin Group containing basaltic layers with zircon U-Pb ages of ~1050 Ma. The basalts and other coeval igneous rocks in the region have geochemical affinity of within-plate rocks, representing a ~1.05-1.1 Ga rifting event. Occurrence of the within-plate rocks does not support existence of a Grenvillian orogenic belt in the region, and thus agrues against previous hypothesis that proposed the Yangtze Block to be located in the interior of the Rodinia supercontinent on the basis of the so-called Grenvillian orogenic belt. The Lala deposit contains 200 Mt of ores with an average grade of 13 wt.% Fe, 0.92 wt.% Cu, 0.018 wt.% Mo, 0.022 wt.% Co, 0.25 wt.% REE2O3 and 0.16 ppm Au, and is one of the largest IOCG deposits in the region. The ores are hosted mostly in meta-vocalnic rocks (albitite) and schists, and are characterized by abundant low-Ti magnetite with subordinate chalcopyrite, pyrite, molybdenite and REE minerals. The paragenetic sequence includes Stage I of Na-alteration, Stage II of Fe mineralization, Stage III of Cu-Mo-REE mineralization, Stage IV of chalcopyrite-pyrite-calcite veins and Stage V of hematite-calcite-quartz veins. Molybdenite of Stage III has a Re-Os isotopic age of 1086 ± 8 Ma, similar to U-Pb ages of the primary allanite as 1067 ± 41 Ma, suggesting that mineralization of the Lala deposit is coeval with the ~1.05-1.1 Ga within-plate magmatism in the region. The secondary allanite has U-Pb ages of 880-850 Ma, comparable to Ar-Ar and Pb-Pb ages of undeformed Stage IV and V veins, representing a younger hydrothermal event. C-O-S isotopes suggest that the Fe and Cu mineralization stages (II and III) at Lala have formed from high temperature magmatic-hydrothermal fluids (385-430ºC). However, compositions of fluid inclusions and minerals demonstrate that the Fe and Cu mineralizing fluids have different compositions. Strontium isotopic compositions of apatite and calcite suggest that the Fe mineralizing fluid has formed from magmatic fluids interacted with late Paleoproterozoic host rocks, whereas the Cu mineralizing fluid with much higher 87Sr/86Sr ratios has possibly involved magmatic fluids that have interacted with older basement beneath. Close association of monazite-bearing apatite, Cu-sulfides and REE-minerals at Lala suggests that REE mobilization and mineralization is genetically related to the Cu mineralizing fluid. This study suggests that the Cu mineralizing fluid contains Cl-, K, CO2, F-, PO43- and CO32- with low Na activity, and is thus responsible for mobilization, transportation and deposition of LREEs in the Lala deposit. / published_or_final_version / Earth Sciences / Doctoral / Doctor of Philosophy

Today’s legal system of China has faced many significant changes. One of the often mentioned challenges concerns the appropriate management and handling of an abundance of new and complex disputes. Due to the popularity of Alternative Dispute Resolution (ADR) in Western countries, it began to draw people’s attention when designing a Chinese dispute resolution policy. With this fact being known and considering China’s domestic political climates and the Chinese practice of using non-confrontational means to solve disputes, one circle of scholars suggested that court mediation (fayuantiaojie, 法院调解) should be enhanced. In June 2009, this suggestion was adopted by the Supreme People’s Court. Concerning the challenges of courts handling disputes in recent years, the SPC has placed a priority on practice of court mediation. However, China’s situation differs from the West, and the existing scholarship lacks empirical research on court-connected ADR. This is especially true in southwest China. Thus, it is quite necessary for legal scholars to assess and examine the operation of court mediation in today’s southwest China in order to answer whether it is a feasible institutional arrangement in the southwest context. This will not only enhance our understanding of the nature and rationale of court-connected ADR at the intellectual level but will also perfect its performance in the future. The purpose of this research is to contribute an empirical study on court mediation and attempts to paint a more complicated and nuanced picture of ADR in southwest China’s context rather than simply copying Western legal narratives to explain China’s legal reality. More specifically, through empirically examining the process of court mediation and the implementation of the relevant policies in practice, this dissertation intends to 1) investigate how court mediation is carried out in southwest China’s grassroots courts in order to answer whether it is a feasible institutional arrangement in the southwest context as well as what the problems are in practice, if any,2) provide suggestions for clarifying and redesigning China’s mediation law in the future and introduce a regionalism-based paradigm to China’s legal studies and dispute resolution policy design as an alternative. Based on empirical studies in the grassroots courts of Yunnan, this dissertation argues that although court mediation now is driven by “politically correct pragmatism”, it is feasible in southwest grassroots China due to the social context and the social embedment of the locals. However, the current “Mediation First” policy is still problematic because it may over-simplify Chinese complexity in the dispute resolution domain and has gone far away from the spirit of ADR by pursuing political goals as its priority and overemphasizing mediation’s role. The way to solve the problem is not to simply or ideologically restrict or limit court mediation; alternatively, it is necessary to establish more straightforward and uncompromising rules to exclude ill-suited cases from being mediated in order to improve its performance. Now is also the time to re-examine China’s nationalized, generalized paradigm concerning both China’s legal constructions and scholarship, and attempt to open up a new regionalism-based paradigm when analyzing China’s legal issues. / published_or_final_version / Law / Doctoral / Doctor of Philosophy
