Project Hue: Report and field study on the water related problems and solutions in and around the Cau Hai lagoon and the Tu Hien inlet, Vietnam
No full textThe Tam Giang-Cau Hai lagoon system, lying in the Thua Thien-Hue province in central Vietnam, is affected by a tropical monsoon climate. This among others is the reason the Cau Hai Lagoon area has a long history of floods and other water related problems. Inhabitants are very dependent on the lagoon, as the main sources of income of people living in the region are fishing, agri- and aquaculture. The project goal has been formulated as follows: Finding an economic as well as technical feasible solution to reduce the water related problems, specifically navigability, salt intrusion and floods, in and around the Cau Hai Lagoon and the Tu Hien inlet and thereby improving the economic development of the region. Concerning flood risk, navigability and salt intrusion the inlet stability and size are important aspects. Using an echo sounder the bathymetry of the inlet has been measured. The measured size of the inlet was one of the input parameters for the hydraulic model that has been set up. This basic model of the Cau Hai basin system was made to test some alternative solutions for the Tu Hien inlet. The different solutions were simulated for five different scenarios. These scenarios include average dry season conditions, average wet season conditions and multiple extreme events. The output of the model for the different alternatives was used to rate the alternatives for a couple of criteria in a Multi Criteria Analysis. Other criteria of the MCA are qualitatively rated. The most promising alternative proved to be the one including a jetty at the northern side of the Tu Hien inlet in combination with a bank protection at the other side. In this way a large part of the littoral drift is blocked, enlarging the equilibrium cross-section of the inlet. This in turn results in a better flood evacuation capacity, navigability and water quality in the lagoon. For both mentioned elements a preliminary technical design is made, resulting in the stone class needed for the armour layers, dimensions of the toe and characteristics of the filter.Hydraulic EngineeringCivil Engineering and Geoscience

Universitas Negeri Malang. Pembimbing: Dr. Joko Sayono, M.Pd.,M.Hum. Kata Kunci: Wayang orang, Tionghoa, Malang Masyarakat Tionghoa telah ada di Indonesia selama berabad-abad. Selama itu terjadi perpaduan budaya dengan budaya lokal. Malang sebagai kota yang sangat berkembang pada masa kolonial menarik banyak pendatang tidak terkecuali pendatang Tionghoa. Pada tahun 1952, di Malang terbentuk kelompok wayang orang Ang Hien Hoo yang diprakarsai oleh orang-orang Tionghoa. Selama berdiri sampai akhirnya berhenti padatahun 1970, perkumpulan wayang orang Ang Hien Hoo mendapat banyak sambutan dari masyarakat Kota Malang. Masalah yang akan dikaji yaitu yang pertama adalah bagaimana ekspresi kebudayaan masyarakat Tionghoa di Kota Malang. Kedua adalah bagaimana dinamika perkembangan perkumpulan wayang orang Ang Hien Hoo pada tahun 1952-1970. Tujuan penulis adalah untuk mendeskripsikan ekspresi kebudayaan masyarakat Tionghoa di Kota Malang. Kedua adalah untuk mendeskripsikan dinamika perkembangan perkumpulan wayang orang Ang Hien Hoo pada tahun 1952-1970. Penulis dalam penelitian ini menggunakan metode sejarah. Metode sejarah meliputi heuristik atau pengumpulan sumber, kritik sumber yaitu untuk menguji kebenaran informasi baik dari segi materi ataupun substansial. Kebenaran yang telah diperoleh kemudian akan dibagi menjadi dua yaitu kritik ekstern yaitu untuk menilai keotentikan sumber. Kedua adalah krikik intern untuk menilai kebenaran isi sumber dan kesaksian. Intpretasi yaitu mencari kebenaran sebuah peristiwa dengan menggunakan nalar penulis berdasarkan fakta yang sudah ditemukan. Historiografi adalah penulisan sejarah yang bersifat kronologis. Penulis juga menggunakan metode sejarah lisan karena masih memungkinkan untuk mendapat informasi dari wawancara dengan pelaku peristiwa. Berdasarkan penelitian ini diperoleh kesimpulan bahwa masyarakat Tionghoa datang ke Malang secara bergelombang dan terdiri atas berbagai suku. Hal tersebut juga mempengaruhi kebudayaan etnis Tionghoa yang ada di Indonesia. Terdapat tiga kebudayaan yang mempengaruhi kehidupan mereka yaitu kebudayaan Jawa, Eropa, dan Tionghoa itu sendiri. Bagi etnis Tionghoa yang sudah terakuluturasi dengan budaya Jawa, kesenian tradisional seperti wayang orang sudah bukan menjadi hal yang asing. Kesimpulan lain yang diperoleh adalah di Malang sendiri pertunjukan wayang orang tidak hanya dilakukan oleh orang-orang pribumi saja melainkan dilakukan juga oleh orang-orang non-pribumi termasuk etnis Tionghoa. Namun perjalanan komunitas tersebut tidak berjalan lama karena terkena dampak dari peristiwa yang melanda Indonesia pada tahun 1970. ABSTRACT Laynani, Khendro Hutomo. 2017. Trail of Ang Hien Hoo : The Dynamics Of Chinese Society of The Wayang Orang Art In Malang In 1952-1970. Thesis. Department of History. Faculty of Social Sciences. State University of Malang. Counselor: (1) Dr. Joko Sayono, M.Pd.,M.Hum. Keywords: Wayang orang, Chinese, Malang The Chinese community has existed in Indonesia for centuries. During their stay, such cultural blend happens between the Chinese culture and local culture. As a highly developed city during the colonial period, Malang attracted many immigrants including Chinese immigrants. In 1952, Chinese community in Malang formed a group of wayang orang named Ang Hien Hoo. During its existence until 1970, Ang Hien Hoo puppeteers got a lot of recognitions from the people in Malang city. This research was conducted to find answers to some of the following problems, the first is how cultural expression of Chinese community in Malang city. The second is how the dynamics of the development of wayang orang group Ang Hien Hoo in 1952-1970. The purpose of this study is to describe the cultural expression of Chinese society in Malang. The second is to describe the dynamics of Ang Hien Hoo group development in 1952-1970. This study is done using method of history research including heuristic or source collection, source critic to test the validity of information both in terms of material or substantial. The valid information then will be divided into two methods of critic namely external critic to assess the authenticity of the source and internal critic to assess the truth of the source and testimony content. Interpretation then will be done to seek the truth of an event by using the author's reasoning based on collected valid information. Historiography is a chronological writing of history. The author also uses oral history method because it is still possible to get information from interviews with the perpetrators of events. Based on this research, it can be concluded that the Chinese community come to Malang periodically and consists of various tribes. It also influences Chinese ethnic culture in Indonesia. There are three cultures that affect their lives namely Javanese culture, European culture, and Chinese culture itself. For Chinese ethnic who have been accredited with Javanese culture, traditional arts such as wayang orang are familiar. Other fact that can be concluded from this research is that puppet show, specifically wayang orang, in Malang is not only done by indigenous people but also performed by non-indigenous people including Chinese ethnic. But the community's journey did not last long as it is affected by the events that happened in Indonesia during the period of 1970
Climate change and the morphological stability of the Tu Hien inlet, Vietnam
No full textHistorically, the coastal zone has always attracted people and across the globe the benefits of inlet systems have made communities settle there. The Tu Hien inlet and the Tam Giang–Cau Hai lagoon system in Vietnam are no exception, as approximately half a million people depend on it for their livelihood. Tidal inlets are also known for their volatile and disruptive nature, because they are dependent on the delicate balances between oceanic processes such as tidal flow, wave action and mean sea level, and riverine processes such as discharges and sediment supply. Disturbances of this balance cause changes in the behaviour of the inlet system, which will have an impact on the surrounding coastal area. The crux is that these processes can all be significantly affected by climate change. The goal of this thesis is to understand the effect of changes in climatic conditions on the morphological stability of the Tu Hien inlet. Achieving this goal was done by studying the present day behaviour of the inlet in order to use this knowledge to validate a process-based model for the present day and subsequently applying climate change scenarios to that model. Newly acquired satellite images show that in recent years (since 1999) the behaviour has changed and the inlet is not closing anymore as was the case in the time before 1999. A conceptual model has been created that captures this behaviour of the inlet and shows that in the present day the inlet is often shifting between being narrowed and open. This cycle is caused by the processes of spit growth and widening due to a certain degree of breaching. A simulation strategy has been drafted which is mainly founded on the yearly seasonal character of the forcing conditions. During a simulation of the northeast monsoon the growth of a spit should be visible; during a simulation of the southwest monsoon a status quo should be maintained. To model this behaviour an existing model (Lam, 2009) has been adapted to include sediment transport and morphology. The adapted model has been calibrated to reproduce the sediment transport up and down the Tu Hien coast and subsequently morphology simulations have been carried out to reproduce the desired morphological behaviour. The results show that after a breach the inlet mouth is narrowing and the cross-sectional area reduces until it reaches a certain stable equilibrium by the end of the northeast monsoon period. During the southwest monsoon there is little wave action and the inlet is tide-dominated, it slightly widens but a status quo is maintained. By reproducing the present day behaviour of the inlet the model has been qualitatively validated and is considered suitable for an investigation into the effects of climate change. Four climate change scenarios consisting of combinations of sea level rise, a change in fluvial run-off and a change in wave climate have been applied to the present day model. The model shows that future changes in river flows and waves are of minor importance compared to the effects of sea level rise with regard to inlet stability. The narrowing behaviour which was apparent in the present day is not observed in the climate change scenarios involving sea level rise. An increase in basin area caused by a higher mean sea level enlarges the tidal prism which results in more flushing capacity of the flows through the inlet. The increased flushing capacity ensures that a larger inlet cross-sectional area is maintained and also enhances the locational stability of the inlet. The predicted increase of the morphological stability can be considered a positive development. An increased cross-sectional area and the lack of a narrowing behaviour means that the future morphological behaviour will not have negative consequences for inlet navigability, water quality, ecology and other socio-economic factors. Even though the predictions show that climate change is likely to have a positive impact on inlet stability for Tu Hien, it is emphasised that the overall impact of climate change on low-lying coastal zones may be significant in a negative sense and deserves continuous attention.Coastal EngineeringHydraulic EngineeringCivil Engineering and Geoscience
Corporate social performance and corporate financial performance: theory and empirical evidence from the recent global financial crisis
No full textThis thesis searches for the theoretical influence of corporate social performance (CSP) on corporate financial performance and to provide empirical evidence for this effect from the recent global crisis. Hence, the author investigates how and why CSP influences financial performance from the international perspective with a global dataset of Fortune World’s Most Admired Companies in three distinctive studies.The first study develops a model on how and why independent directors using CSP disclosure affect profitability. The model is built on Schmidt and Keil’s (2013) theory of the conditions and mechanisms that make resources valuable to a firm. The regression results support the proposed model in a way that the synergy of independent directors using CSP disclosure probably increases profitability. The second study tests the agency theory on the impact of executive remuneration combining with CSR disclosure on profitability. The study finds that a combination of executive remuneration and CSP disclosure are likely to improve profitability; however, higher salary and stock might be the drivers that affect executives to disclose more information on CSP, which enhances the corporate reputation in CSP. The third study tests the theory of transaction costs in a model on the influence of CSR on profitability intervened by corporate governance. The data support the model, suggesting that well-informed and good governance is the condition for a positive influence of CSP on financial performance.The novel contributions of the thesis are as follows. From an international perspective and use of a global-level dataset, the thesis confirms and extents the global theories related to corporate governance, and opens up the new research avenues. Empirically, this thesis is the first that proposes and tests a model on how and why independent directors using CSP disclosure affects profitability, underpinned by Schmidt and Keil’s (2013) function. Methodologically, the studies used the two measures of CSP in terms of disclosure and reputational rank; the structures of two simultaneous equations were used to fit the data. Further, the problem of endogeneity was addressed in the studies.At the firm level, the thesis implies that first, the strategy in which independent directors use CSP is likely to improve financial performance due to the willingness to pay for the increased resources and social capital of their firm. Second, the study results raise the concerns on managerial manipulation of CSP disclosure due to agency problems and information asymmetry problems, thus recommending independent directors’ role of monitoring CSP. Third, the study suggests that positive effect of CSP on financial performance is conditional on the intervention of transparent and good governance. Moreover, the thesis reveals the advantages of the two coordinating forms of economic activities from the recent financial crisis, one based on networks and the other on governance hierarchy. These should be macro policy considerations during periods of economic recession when the market mechanism might fail

Dynamique de la matière organique d'un lixisol plinthique sous l'effet de la mise en culture et des pratiques culturales (Sud-Ouest du Burkina Faso)
No full textLa matière organique des sois (MOS) joue un rôle prépondérant dans la fertilité des sols et dans la réduction des gaz à effet de serre en tant que source ou puits de carbone vis à vis de l'atmosphère. On sait que le mode de gestion des terres influe directement sur la MOS. L'objectif de ce travail est double: (1) évaluer le potentiel de stockage du C d'un lixisol plinthique du Sud-Ouest du Burkina Faso sous trois modes de gestion différents: végétation naturelle. culture continue sans fumure et culture continue avec fumure, (2) approcher les déterminants du stockage de la MOS et du C dans le soi. La méthodologie mise en oeuvre concerne in situ la caractérisation du milieu (cartographie des sols. mesures des densités apparentes et échantillonnage) et en laboratoire le fractionnement granulométrique de la MOS et les mesures des teneurs en C et N du sol et des fractions granulométriques. Les résultats montrent que les stocks de C sont de 81,9 t ha-' sous savane contre 30 sous culture continue. le C étant principalement contenus dans les horizons de surface. Le fumier traditionnel apporté à raison de 2 t ha-' an-' induit une augmentation, de 8 t ha-'. Le fractionnement granulométrique montre: (i) que les teneurs en C sont plus élevées dans les fractions "argileuses" (ii) que le mode de gestion des terres influence principalement les teneurs en C des fractions grossières (200-2000 µm) et des fractions fines (0-20 µm) en surface. Sur un plan méthodologique, cette étude a aussi permis de montrer l'importance de la phase de prélèvement dans l'évaluation des stocks de C

Dynamique du carbone dans un acrisol ferrique du Centre Ouest Burkina : influence des pratiques culturales sur le stock et la qualité de la matière organique
No full textL'évaluation des potentialités de stockage du carbone dans les agro-systèmes cultivés est à l'ordre du jour. Dans ce contexte, notre objectif de recherche est d'évaluer la dynamique des stocks de C dans le sol et de préciser les mécanismes en jeu, sous l'action de pratiques culturales, dans un Acrisol ferrique du Burkina Faso. Cette étude s'appuie sur des essais "longue durée" permettant la prise en compte du facteur temps pour comprendre, quantifier et modéliser l'évolution des stocks de C sous l'action de pratiques culturales, usuelles, mais pouvant être optimisées: la fertilisation minérale, les apports de matière organique (paille, compost et fumier) et le travail du sol (grattage et labour). Les déterminations sont faites au champ et au laboratoire: (1) au champ sur le sol (caractérisation morphologique, densité apparente) et sur les cultures (rendements), (2) au laboratoire sur les matières organiques apportées (composition biochimique) et sur le sol (dosage de C et N, diffractométrie et fractionnement granulométrique). Les résultats confirment que la mise en culture entraîne une diminution des stocks C par rapport à la jachère herbacée de départ, après 10, 20 et 40 ans de culture continue avec labour, respectivement de 42, 44 et 68%. Le niveau potentiel de stockage de C sur ce type de sol mesuré sur la jachère herbacée non dégradée est de 20,6 t ha-1 dans l'horizon 0-20 cm. Les pratiques testées les plus performantes permettent d'attéindre 45 à 90% de ce stock potentiel, selon la durée de l'expérimentation. Les coefficients de minéralisation nette annuels sont élevés, compris entre 0,035 et 0,038. Les coefficients isohumiques sont de 18 et 22% respectivement pour des doses de 40 et 5 t MS de fumier ha-1 2an-1. La modélisation des stocks de C à l'aide du modèle RothC (horizon 0-20 cm) nous conduit à admettre une cause jusque là insoupçonnée de pertes ou de transfert à partir du fumier, de l'ordre de 67%, qui n'entre donc pas dans l'amélioration des stocks de C du sol de l'horizon considéré, vraisemblablement liée au rôle de la macrofaune du sol. Le fractionnement granulométrique montre l'importance des fractions 0-20 p.m et soluble. Cette dernière est la plus forte (30% du Ctot) en absence d'apport de MO. Les fractions fines sont relativement stables alors que les fractions grossières enregistrent des variations importantes, notamment à la baisse en absence d'apport de MO. Lorsque le fumier est apporté simultanément à l'engrais N, il favorise un stockage préférentiel de C dans les fractions fines, attestant l'intérêt de cette pratique sur la stabilisation de la MOS. La définition d'une valeur critique de C dans le sol comprise entre 6 et 7 mg C g-1 est confortée par les résultats convergents de deux approches: l'analyses des rendements du sorgho par la méthode de "la courbe enveloppe" et la définition d'une valeur seuil de C pour la durabilité des systèmes (Feller, 1995) qui donnent respectivement environ 6 et 6,8. En deçà de 6 mg C g-1 les rendements chutent, au delà ils sont stabilisés. Accroître significativement le stockage de C dans le sol est possible à partir des pratiques usuelles mais nécessite leur optimisation. Cette étude débouche sur des actions possibles mais conclut à la nécessité de prendre en compte les activités macrofaunique et microbienne de ce sol en interaction avec les MO apportées pour mieux maîtriser les flux et le bilan organiques
Évaluation de Stocks de Carbone dans un Sol Ferrugineux sous L’Apport de Composts de Déchets Urbains: Cas de Gampéla au Burkina Faso
No full textAu Burkina Faso, l’utilisation agricole de déchets urbains se développe progressivement dans les zones urbaines et péri-urbaines. Cette étude visait à évaluer l’effet de deux modalités d’apport de six formules de composts de déchets urbains sur les stocks de carbone et les propriétés physiques et chimiques d’un sol ferrugineux dans un essai agronomique sous sorgho à Gampèla, au Burkina Faso. Pour chaque modalité d’apport et pour chaque formule de compost, 3 t MS ha-1 an-1 ont été apportées sur des parcelles élémentaires. Des échantillons de sols ont été prélevés sur les profondeurs 0-10cm, 10-20cm et 20-30cm. Des méthodes d’analyses conventionnelles ont été employées afin de déterminer les propriétés physiques et chimiques des sols. Les traitements sous composts ont été comparés à un témoin sans fertilisation. Le mode d’apport et le type de compost ont eu des effets sur les propriétés des sols. Les composts ont entrainé une réduction de la densité apparente, un taux de fractions fines plus élevé, des teneurs et stocks en C et N de l’horizon de surface plus importants. Comparativement au témoin, ces effets étaient significatifs pour la densité apparente, les fractions fines et les stocks de carbone dans les parcelles sous apport de composts. La corrélation entre les stocks de N et la croissance de sorgho a montré un lien positif. Les composts les plus performants étaient C1, C2 et C5. La valorisation agricole des composts de déchets urbains peut contribuer à améliorer la fertilité physique et chimique de même que la productivité des sols sous culture de sorgho
Two-magnon scattering in the 5d all-in-All-out pyrochlore magnet Cd2Os2O7
No full text5d pyrochlore oxides with all-in-All-out magnetic order are prime candidates for realizing strongly correlated, topological phases of matter. Despite significant effort, a full understanding of all-in-All-out magnetism remains elusive as the associated magnetic excitations have proven difficult to access with conventional techniques. Here we report a Raman spectroscopy study of spin dynamics in the all-in-All-out magnetic state of the 5d pyrochlore Cd2Os2O7. Through a comparison between the two-magnon scattering and spin-wave theory, we confirm the large single ion anisotropy in this material and show that the Dzyaloshinskii-Moriya and exchange interactions play a significant role in the spin-wave dispersions. The Raman data also reveal complex spin-charge-lattice coupling and indicate that the metal-insulator transition in Cd2Os2O7 is Lifshitz-type. Our work establishes Raman scattering as a simple and powerful method for exploring the spin dynamics in 5d pyrochlore magnets. © 2017 The Author(s)5
