This thesis examines the biodiversity and evolutionary ecology of Lumnitzera mangroves in the Indonesian Archipelago. Using a combination of genomics and metabolomics, the study arrived at several key findings: (1) Investigation into 14 populations of L. littorea and 21 populations of L. racemosa revealed low genetic variation, with significant barriers like Sulawesi and the Java Sea influencing genetic differentiation. (2) Specifically for L. littorea, Wallace's line was identified as a key biogeographical separator, marking divergent evolutionary pathways and separating phylogroups, whereas L. racemosa showed a mixing population in the Wallacea region. (3) Uniquely, the research discovered a diversity in sulfated constituents, including previously unknown compounds like Lumnitzeralactone. (4) Further emphasizing the mangroves' medicinal importance, antibacterial potential was uncovered in the species. (5) The study innovatively linked phylogenetic data with chemical analyses, offering a comprehensive view of mangrove evolution and ecology. (6) Finally, the findings highlighted the need for specific conservation strategies, considering the genetic differentiation within populations, to protect the mangroves' ecological significance and medicinal value across Indonesia.:Preface 4 Summary 5 Zusammenfassung 10 1.

Studies on the development of the accountancy profession in the ex-colony countries have recently adopted theoretical and methodological frameworks that linked such development with the socio-historical context of these countries as former colonies or dependants of the more developed countries. More specifically, they associate the emergence and development of the accountancy profession in these countries with the historical and contemporary global expansion of capitalism. However, there is still a need for further research. First, how global expansion of capitalism penetrates is different across different country settings. Hence, this process would be best understood by incorporating the socio-political, economic and historical specificity of the given country. Second, previous studies emphasize the internal dialectic contradictions of capitalism in analysing the changes and dynamics of the profession in ex-colony countries. Recent literature, however, has introduced methodologies that recognize the need to acknowledge the existence of any rivalling structures as possible external sources of the dialectic progress of capitalist expansion. In regard to this, the socio-political and historical context of Indonesia may offer a case of how the interactions between global expansion of capitalism and existing rivalling structures may shape the development of the accountancy profession. The need for further research is amplified by the fact that previous studies on the Indonesian accountancy profession have generally ignored the influence of these wider socio-political factors. The primary aim of this study is thus to investigate how the accountancy profession has emerged and developed in Indonesia over the last five decades. To achieve its objectives, this research draws insights from the tradition of the globalization theory as a critique to global expansion of capitalism and Robert Cox historical structure methodology. The central argument of this thesis is that the development of the Indonesian accountancy profession followed the changes in the country¿s system of political economy, which in turn has been heavily influenced by the relationship between ex-colony countries with their former colonizers within the context of the capitalistic world order. In other words, this study accepts the contention that the spread of the Western-style accountancy profession across the globe, including Indonesia, was the consequence of global expansion of capitalism. However, the working and the extent of such influence is also shaped by alternative social structure(s) existing at the global level and/or emanating from the complexities of the Indonesian historical and societal context. To substantiate this argument, the study uses document analysis to understand the development of the Indonesian accountancy profession during the three main periods in its history. In the first period (1954 ¿ 1966), the analysis shows that the Westernization of the accounting profession was compromised by Indonesian nationalism, ideological division amongst the Indonesian leaders and the Cold War. In the second period (1967 ¿ 1997), the process was compromised by the oligarchic capitalism of the New Order political regime. The Westernization of the profession could only reach full speed after the 1997 Asian financial crisis, which has undermined the politico-business coalitions under the New Order that had prevented Indonesia from fully integrating into the global capitalist economic order. / Bradford University School of Management

This dissertation examines an Indonesian-North American version of an evolving, transnational and hybrid multimedia art form which has come about through forty years of adaptations made by cross-culturally located artists in creative conversation with Indonesian performers involved in the Javanese and Balinese forms of musical theatre known as wayang. Wayang theatre employs puppets and other components including gamelan music (Indonesian percussion instruments, drums, flutes, strings and vocals). Given this complexity, there are many possibilities for variations, changes, and hybridization. In this research project, I analyze aspects of this hybrid performance by analyzing select Indonesian-North American wayang performances, as case studies. In order to isolate complex changes and various adaptations of wayang performances in the North American setting, I also analyze and contextualize a hybridization of Javanese and Balinese wayang performances. As a performance art form, wayang has always been changing historically—at some points more quickly and dramatically than at other periods of time, thus resisting firm categorization that would provide a baseline for comparison. I have developed the wahiyang theoretical framework as an analytical tool to identify the influence of North American culture on the wayang performances in my case studies. I argue that new genre of wayang is emerging, creating a hybridized form that I call wahiyang gaya NA. This process has progressed to the point that wahiyang gaya NA can be said to represent a new genre of multimedia world art, which combines elements of local and global artistic practises, making the form even more flexible and adaptable than its original forms in Indonesia. The gradual spread and popularization of wayang in North America has definite historical contexts, namely the early 19th-to-mid 20th century conjunction of decolonization and Third World nationalism, with the more recent decades’ layering of multiculturalism and push towards conscious cultural responses to economic globalization. This developing continuum of new hybrid forms spans a spectrum of cultural inclusion and expansion of wayang and new components. At times these may be seen as wayang influence upon Western performance practice; at other times an entire Indonesian wayang production with additional elements added from Western music, theater, and other disciplines may be presented. These developments signify an enhanced and expanded exchange of cultural products between the nations of the world, taking place in an expanded space for dialogue between the artists of the developed and developing countries. I will show, using case studies, how this process has produced and is producing a new branch of wayang as part of a continuum of hybridized wayang forms. By examining selected performance collaborations that have taken place over the last 40 years, I will provide a detailed analysis, which for the first time, lays out the components that constitute the variation of wayang art performance that has developed in response to geographical and cultural contexts of the Pacific Northwest of USA and Westcoast Canada. / Graduate / 2018-04-12 / 0377, 0357, 0465 / sutrisno@uvic.ca
