La rivière Saigon, qui constitue un sous bassin du fleuve Nha Be, est située dans le sud du Vietnam. Cette rivière a une longueur d'environ 250 km et le bassin versant total à une surface de 4717 km2. Le réservoir de Dau Tieng, situé en amont de la rivière Saigon, a été construit pour mieux gérer l’irrigation, lutter contre les inondations et contrôler l’intrusion d’eau salée. En traversant HCMC, la rivière Saigon est connectée à plusieurs canaux puis rejoint la rivière Dongnai pour devenir le fleuve Nha Be qui traverse la zone de mangrove de Can Gio et se jette dans la mer de l'Est. La rivière Saigon et son bassin versant sont situés dans la plaine côtière et sont soumis au balancement quotidien des marées.L'objectif général de cette thèse est (i) d’évaluer l'état trophique de la rivière Saigon - Dongnai, (ii) d’étudier les processus à l’origine de la dynamique des nutriments, en particulier le rôle des sédiments en suspension, du mélange turbulent et du gradient de salinité, afin d'estimer la capacité de rétention par rapport aux flux d'éléments nutritifs; (ii) d’utiliser ces mesures de terrain et de laboratoire pour envisager une simulation numérique de ce système estuarien.La première étape de cette thèse a consisté en une étude des concentrations en nutriments (N, P, Si) sur quatre sites d’échantillonnage dans le système de la rivière Saigon – Dongnai. Les mesures ont été réalisées deux fois par mois de juillet 2015 à décembre 2017 pour évaluer les niveaux de concentration en éléments nutritifs et l’état d’eutrophisation. Cette thèse a mis en évidence un excès de nutriments dans HCMC avec des concentrations de NH4+ et de PO43- atteignant en moyenne 0.7 mgN L-1 et 0.07 mgP L-1, respectivement. Nous avons observé que des rejets domestiques non traités entraînaient une dégradation de la qualité de l’eau de la rivière Saigon, avec une valeur extrême de biomasse algale (150 µChl-a L-1) et des périodes d’hypoxie (DO < 2 mg L-1), principalement en saison sèche. L’eutrophisation de la rivière dans la zone urbaine dense n'a pas d'effet clair en aval, car la masse d'eau eutrophie de la rivière Saigon est efficacement mélangée avec les masses d'eau de mer et de la Dongnai pendant chaque cycle de marée. Ce qui met en évidence le rôle tampon (capacité de métabolisation) de l’estuaire entre les apports amont et la mer.Sur la base d'enquêtes de terrain et d’expérience en laboratoire, nous avons évalué les causes de l'eutrophisation de la rivière et étudié la capacité d'adsorption-désorption du phosphore sur les sédiments en suspension dans le gradient de salinité. Les enquêtes sur le terrain ont montré un impact clair de la mégapole, le P total augmentant de trois fois dans le centre de HCMC, par rapport aux valeurs en amont. En aval, dans la zone estuarienne mélangée par des marées, le P total descend à moins de 0.5 gP kg-1. Les expériences en laboratoire ont montré le rôle clé de la concentration en sédiments cohésifs en suspension sur la capacité d’adsorption de P sur les particules dans le gradient de salinité.Dans cette thèse, nous avons également analysé une base de données des nutriments, des sédiments en suspension et des rejets d’eau de 2012 à 2016 (données du service de surveillance de la qualité de l’eau vietnamien de la province d’HCMV). Neuf sites le long de la rivière Saigon et un site dans la rivière Dongnai ont permis de déterminer l’état de référence à l’amont et à l’aval d’Ho Chi Minh Ville. Les flux calculés permettent de dresser un premier bilan sédimentaire et nutritif à l’échelle des fleuves Saigon – Dongnai, de discuter de la contribution de chaque sous bassin aux flux totaux et de dresser des hypothèses sur l’état géomorphologique et environnemental actuel et futur des zones estuariennes et côtières
The Saigon River, a part of Saigon – Dongnai River basin located in Southern Vietnam, is about 250 km long with a catchment area of 4,717 km2. The Dau Tieng reservoir in the upstream of the Saigon River has been constructed for irrigation, flood protection purposes and the control of the intrusion of saline water. When flowing through HCMC, Saigon River is connected with canals and then joins Dongnai River to become the Nha Be River flowing through Can Gio Mangrove to the East Sea. Draining a low elevation coastal zone (LECZ), Saigon River is affected by the asymmetric semi-diurnal tides.The general goal of this thesis is to (i) assess trophic status in the Saigon – Dongnai River, (ii) assess the processes that lead nutrient behavior in the salinity gradient to estimate retention capacity with respect to the nutrients fluxes and (iii) calculate nutrient budgets to further be used for numerical simulations.The first step of this thesis consisted in a survey of nutrient concentrations (N, P, Si) at four sampling sites within the Saigon – Dongnai River system, which was carried out bi-monthly from July 2015 to December 2017, allowing to quantify the levels of nutrient concentrations and of indicators of eutrophication. This thesis pointed out an excess of nutrients in HCMC with concentrations of NH4+ and PO43- averaging to 0.7 mgN L-1 and 0.07 mgP L-1, respectively. We observed that untreated domestic discharges lead to the degradation of Saigon River’s water quality with extreme value of algal biomass (up 150 µChl-a L-1) and hypoxia conditions occurring episodically (DO < 2 mg L-1) during dry season. The eutrophic issue in the city center has no clear effect downstream because eutrophic water mass from Saigon River is efficiently mixed with Dongnai and sea water masses during the semi-diurnal tidal cycle, leading to efficient metabolism of nutrients within the estuarine partBased on field and laboratory surveys, we assessed the eutrophication of the river, and investigated P adsorption-desorption capacity onto suspended sediment (SS) within the salinity gradient. Field surveys showed a clear impact of the megacity, total P increasing three fold in HCMC center, as compared with upstream values. Downstream, in the tidally mixed estuarine area, the total P lowered to less than 0.5 gP kg-1. Laboratory experiments were carried out to characterize the influence of SS concentrations, salinity and turbulence on sorption/desorption processes. Among these observed variables, SS concentration was shown to be the main driver for adsorption capacity of P onto SS in salinity gradient. This underlines the role of cohesive sediment dynamics, as an important driver of nutrient dynamic in this estuarine river system.In this thesis, we analyzed the nutrients, suspended sediments and water discharges database from the Vietnamese Center of Monitoring of the Department of Natural Resources and Environment (period 2012 to 2016). Nine sites along the Saigon River and one site in the Dongnai River were used to identify the reference water status before HCMC and the increasing fluxes from upstream to downstream. The calculated fluxes allow drawing a first sediment and nutrients budget at the scale of the Saigon – Dongnai Rivers and discussing the contribution of each sub basins to the total fluxes to the estuarine and coastal zones. Add one sentence pointing out the main result of this 2005-2016 dataseries analysis

Ce travail de thèse est consacré à l’étude de la structure électrique de la croûte terrestre dans deux régions du Vietnam, au Nord dans le delta du Fleuve Rouge et au Sud dans la région de la faille de la Rivière Saigon, et en Afrique de l’Ouest, où les données utilisées sont celles acquises durant l’Année Internationale de l’Electrojet Equatorial (AIEE). La technique utilisée est celle du sondage magnétotellurique. Deux des régions étudiées (le sud du Vietnam et l’Afrique de l’Ouest) sont situées au voisinage de l’équateur magnétique. Du fait de la présence de l’électrojet équatorial, l’hypothèse de l’onde plane, sur laquelle est basée la magnétotellurique, n’y est vérifiée que pour une gamme de périodes limitée. La modélisation de l’induction par un électrojet gaussien nous a permis de caractériser l’effet de source associé à l’électrojet équatorial, et de déterminer pour chacune des zones étudiées les gammes de périodes pour lesquelles cet effet de source est négligeable. Nous avons par ailleurs montré que l’effet de source associé à l’électrojet équatorial dépend des principales caractéristiques de la structure électrique du sous-sol, et de la distance entre le centre de l’électrojet équatorial et la position examinée. Dans le delta du fleuve Rouge, le profil magnétotellurique est orienté SO-NE. Long d’environ 32 km, il recoupe les failles majeures du système de failles du Fleuve Rouge. Les données magnétotelluriques ont été inversées pour obtenir une coupe transversale de résistivité électrique pour les trois premiers kilomètres. Cette coupe de résistivité électrique et une coupe de densité obtenue par modélisation des données gravimétriques acquises le long du même profil, ainsi que des informations déduites de forages effectués au voisinage du profil ont été utilisées pour proposer une coupe géologique de la région étudiée. Dans la région de la faille de la Rivière Saigon, le profil magnétotellurique, long d’environ 15 km, recoupe le trajet supposé de la faille. La structure électrique des premiers kilomètres de la croûte a été déterminée par inversion 2-D des données pour les gammes de périodes qui ne sont pas affectées par l’électrojet équatorial (< 0,7 s). La coupe transversale de résistivité électrique ainsi obtenue nous a permis de proposer une nouvelle localisation de la faille de la Rivière Saigon, à la limite entre un domaine résistant, le bloc de Da Lat au nord-est, et un domaine moins résistant, le bloc de Can Tho au sud-ouest. Cette nouvelle localisation est à environ 2,2 km au sud-ouest de la localisation généralement supposée pour cette faille. En Afrique de l’Ouest, nous avons montré que les données de jour sont affectées par l’électrojet équatorial pour toute la gamme de période étudiée (>120 s); ces données n’ont donc pas été utilisées pour déterminer la structure électrique de la croûte et du manteau supérieur. L’inversion 2-D des données de nuit, montre la présence d’une structure subverticale, relativement conductrice, qui sépare le Craton Ouest-africain très résistant des terrains situés sous le bassin du fleuve Sénégal
This thesis is devoted to the study of the electrical structure of the Earth’s crust in two regions of Vietnam (the Red River Delta in the north and the region of the Saigon River fault in the south) and in West Africa. The data were those acquired during the International Year of the Equatorial Electrojet (IYEE). The technique used is the magnetotelluric (MT) sounding method. Two of the regions studied (southern Vietnam and West Africa) are located near the magnetic equator. Due to the presence of the equatorial electrojet in these regions, the assumption of plane wave, on which MT relies, is valid for a limited range of periods. Modeling of the induction by a Gaussian electrojet allowed us to characterize the source effect associated with the equatorial electrojet, and to determine for each studied region the period ranges for which the source effect is negligible. We have also shown that the source effect associated with the equatorial electrojet depends on the main features of the electrical structure of the basement, and the distance between the center of the equatorial electrojet and the location of the considered station. In the Red River Delta at the north, the MT profile is oriented SW-NE. It is about 32 km long, and goes across the major faults of the Red River fault system. MT data were applied 2-D inversion to obtain a electrical cross-section for the first three kilometers of the crust. This electrical cross-section, a density cross-section obtained by modeling of gravity data collected along the same profile, and information derived from holes drilled in the vicinity of the profile, both were used to construct a geological section of the study area. In the region of the Saigon River fault, the magnetotelluric profile is about 15 km long. It goes across the supposed location of the fault. The electrical structure of the first three kilometers of the crust was determined by 2-D inversion of data for periods which are not affected by the equatorial electrojet (< 0.7 s). The electrical cross-section obtained allowed us to propose a new location for the Saigon River fault; it corresponds to the boundary between a resistant domain, the block of Da Lat in the north-east, and a less resistant domain, the block of Can Tho in the south-west. This new location is about 2.2 km southwest of the location currently assumed for this fault. In West Africa, we have shown that electromagnetic impedances derived using day time data are affected by the equatorial electrojet for the whole range of period studied (> 120 s), so these data have not been used to determine the electrical structure of the crust and the upper mantle. The 2-D inversion of nighttime data shows the presence of a subvertical structure, relatively conductive, which separates the West African Craton which is very resistant from the geological structures beneath the Senegal River basin

The 1968 Tet offensive is referred to as the turning point in the Vietnam War. Of the many battles of Tet, the attack on the American Embassy in Saigon stands out. It is neither the battle's size nor its casualties that makes it important. The significance of the embassy attack lay in the way it was conveyed to the American public. I argue that the 1968 attack on the American Embassy in Saigon served as a catalyst for the media to criticize the government's conduct of the Vietnam War and aided in turning the American public against the war. The news media aided this shift in opinion through its coverage and subsequent narrative of the attack on the U.S. Embassy. My goal is to examine the ongoing relationship between the media and the public by examining the major newspapers; the New York Times, Los Angeles Times, Washington Post, and the Christian Science Monitor, and the major news magazines, Time, Life, and Newsweek. It is important to observe that the news media is still a business that must appeal to its customers (readers and advertisers). As the public view changed, the media reflected that change in order to appeal to its audience. At the same time the news media's consistency of war coverage and reflection of public sentiment helped further perpetuate the public's disapproval of the conflict and continued this cycle. How did the media report the unexpected attack on the American Embassy and how did it affect public opinion of Vietnam? How does the press coverage of the embassy attack fit in the larger context of media coverage of the Tet Offensive in determining the relationship between the media and the public? Which one influenced the other in creating opinions of the Vietnam War? These questions are important not only because the news media was a major contributor to Americans' knowledge of the war but also because of the role the media plays in the society of the era and how its narrative became the historical narrative. My focus on the U.S. Embassy attack during the Tet Offensive is due to the chaos that surrounded the attack not only from the military's perspective but also from the media's. Since the attack took place in Saigon, headquarters of the media companies' in Vietnam, it was readily accessible to journalists. The attacks surprised the military, government, and the public, and in the midst of the chaos the media was there to report on it all. Reports constantly changed as to what went on and frequently contradicted "official" statements. These are the reasons why the media's involvement in the Vietnam War was filled with misconceptions and controversy.

Between 1964 and 1973, the United States sent over 48,000 Puerto Rican soldiers to fight the war in Vietnam. While many enlisted voluntarily, many others were sent as draftees, subject to conscription as citizens of the United States. This is the starting point of this thesis, which looks at the intersection between citizenship, nationality and military service in relation to Puerto Rican identity at the time of the Vietnam War. This project focuses on the experiences of three distinct groups. First, it uses newspaper and archival research to explore opposition to the draft by Puerto Rican nationalists on the island, who used conscription as a tool to challenge the meaning of their citizenship. They questioned how a state that denied them the right to vote could require them to give the ultimate sacrifice and challenged both the moral and legal dimensions of conscription as it applied to the island. Next, it moves to the Puerto Rican barrios of New York to look at second-generation Puerto Ricans who came of age during the era of civil rights and the Vietnam War. Through the lens of popular culture, it looks at the early development of Puerto Rican stereotypes in Hollywood films and the way that these were challenged by a new generation of writers and activists by the close of the sixties. Finally, it turns to interviews and memoirs of Puerto Rican veterans to present a personal account of what it meant to be Puerto Rican in the U.S. armed forces at the time, and questions the success of the military’s effort to construct soldiers who would remain loyal American citizens after the war. Taken separately, each of these chapters provides a small glimpse of the Puerto Rican experience during the Vietnam War era, but taken together they contribute to our understanding of the ways in which the war, and the environment it created, played a role in the efforts of Puerto Ricans to reclaim and reconstruct their collective identity during this period.

Ho Chi Minh-Ville (Saigon) est reconnue universellement en tant que ville historique végétale et hydraulique. Trente ans après le lancement de la politique de Renouveau (1986), elle s’est transformée en une métropole trépidante de plus de 10 millions d’habitants faisant face à une urbanisation accélérée, tant horizontale que verticale. Alors que son centre est métamorphosé par la construction de nombreuses grandes tours résidentielles, commerciales et de bureaux, ses territoires périurbains et ruraux s’urbanisent et se modernisent par le biais des Nouvelles Zones Urbaines (KDTM) construites depuis 1996. Dans cette fabrique spatiale concrète, les interventions des investisseurs et opérateurs privés jouent un rôle déterminant. Ils sont actuellement des acteurs clés des KDTM qu’ils orientent vers un cadre de vie mondialisé en direction des classes aisées. Cependant ces nouveaux quartiers ne correspondent pas toujours à leurs objectifs initiaux, ni même à leurs concepts et à leur communication publicitaire. Cet écart découle en premier lieu d’une gestion urbaine hiératique. Les textes officiels et les plans directeurs sont encore trop peu consolidés, les autorités municipales et locales ne contrôlant dans les faits que difficilement une expansion métropolitaine galopante. A partir de recherches documentaires, cartographiques, photographiques et d’analyses in situ et in vivo, la thèse traite la question centrale des modalités de privatisation des KDTM de 1996 à nos jours. Elle met en lumière les modes opératoires de la production urbaine des acteurs privés ainsi que les effets en retour des KDTM sur les mutations spatiales et sociétales de la grande métropole économique du Vietnam
Ho Chi Minh City (Saigon) has been universally and historically known as a planted and hydraulic city. Thirty years after the beginning of the Renewal policy (1986), it has become a hectic megalopolis inhabited by more than 10 million people. Moreover, it is facing an accelerated urbanization, which is both horizontal and vertical. While its center is transformed through the construction of many high residential, commercial and office towers, its peri-urban and rural areas are urbanized and modernized thanks to the construction of New Urban Areas (KDTM) whose construction starts from 1996. In this concrete urban fabric, interventions of private investors and operators play an important role. They are currently key developers of KDTMs, who contributes to the development of globalized living environments for the upper class. However these new neighborhoods do not always match their initial purposes, concepts and advertising. First, this gap results in a hieratic urban management. Official texts and master plans are still not accurate, and municipal and local authorities have difficulties to control a quick metropolitan expansion. Based on documentary, cartographic, and photographic research, as well as in situ and in vivo analysis, the thesis looks into the KDTM privatization’s modalities, from 1996 to the present day. It highlights the modes of private actors’ urban production, as well as the impact of KDTMs on the spatial and social changes of the great Vietnamese metropolis

Le système fluvial Saigon-Dong Nai (SG- DN) est la plus importante source d'eau pour les douze villes et provinces du sud du Vietnam. Il est aujourd'hui gravement pollué par les activités humaines, agricoles, industrielles et domestiques, constituant une menace pour la vie de millions de personnes. Le ministère vietnamien des Ressources naturelles et de l'environnement a rapporté que les rivières ont reçu environ 1,54 milliard de litres d'eaux usées provenant de 70 parcs industriels par jour, dont 35% de déchets médicaux non traités, et que des tests effectués depuis 2006 ont montré des niveaux élevés de pollution, en particulier de substances toxiques organiques. Jusqu'à présent, il n'y a pas de données sur la diversité microbienne dans le système fluvial SG-DN, en particulier dans les sédiments, où la plus grande partie de la biomasse microbienne est généralement localisée. Les échantillons de sédiments ont été recueillis, réseau hydrographique national SG-DN, à 13 endroits dans les rivières représentant des emplacements pollués. Afin de caractériser les populations microbiennes présentes sur nos sites choisis, l'ADN total des échantillons environnementaux a été extrait et amplifié dans les régions V3 à V1 de l'ADNr 16S. L'étude a révélé que la population microbienne changeait de l'amont vers l'aval au niveau du phylum, du genre et de l'OTU après avoir traversé la zone de population industrielle et dense. De plus, les canaux du bassin versant SG-DN sont fortement pollués par de fortes concentrations de composés organiques (PAH) et possèdent différentes communautés bactériennes par rapport aux échantillons des rivières
The SaiGon-DongNai (SG-DN)river system is the most important major water source for all twelve Southern Vietnam cities and provinces and is now dramatically polluted by industrial and living activities, giving “a threat” to the lives of millions people sharing this water source. The Ministry of Natural Resources and Environment of Vietnam reported that the rivers received around 1.54 billion liters of waste water from 70 industrial parks per day, including 35 percent of untreated medical waste, and tests since 2006 have found pollution in this river has increased to “serious levels”, an especially high concentration of organic toxic substances. Until now, there is no data on the microbial diversity in SG-DN river system especially in the sediments, where most of the microbial biomass is generally located. The sediment samples were collected in 13 locations across the rivers representing warning polluted locations done by Mr. Nguyen Thanh Hung of the National Water Qualifying in SG-DN river system. In order to characterize the microbial populations present at our chosen sites, the total DNA from the environmental samples were extracted and amplified at the V3 to V1 regions of the 16S rDNA. The study revealed that microbial population changed from upstream to downstream at the phylum, genus and OTUs levels after running through the industrial and dense population zone. Moreover, the canals of the SG-DN river catchment are heavily polluted with high concentrations of organic compounds (PAHs) and possessed different bacterial communities compared to the samples from the rivers

This thesis examines the political activism of Vietnamese Engaged Buddhism in the 1960s, particularly the Struggle Movement for social justice and democracy of 1963 and the Peace Movement of 1966. It explores the Buddhist leaders' motives and their political means to deal with Saigon military government and senior advisors to the White House. The thesis sets out to prove that socially and politically Engaged Buddhism is inherent in the Buddhist tradition and not alien to Buddha's teachings. It also proves that Vietnamese Buddhism has always been engaged since the dawn of Vietnamese history. The Buddhism Peace Movement is assessed in accordance with Buddhist principles such as non-violence and non-attachment to temporal power. Except a few minor incidents, it was found that the Buddhist leaders strictly adhered to the non-violent principle and Vietnamese Engaged Buddhism could have provided a political alternative, the Politics of Enlightenment, which could avert the unnecessary destruction of the Vietnam War

ABSTRACT The Vietnam population has been reaching the number of more than 90 million with an economic increasing development as well which is a very potential market for retailing industry including the joining of many foreign retailers. Moreover, it is no limitation joining Vietnam market for these enterprises after Vietnam had taken part in WTO since November 1st, 2015. In such a diverse market, it is necessary for Vietnamese retailers to have their own special business strategies. For this reason, the thesis aims to analyze the Vietnamese retail market in order to find out developing opportunities as well as the threats of Saigon Co-op Mart. Then it uses analysis tools to examine and analyze the main factors affecting the company growth. Finally, the thesis points out the best strategies and suggests some solutions follow to implement these strategies. For methodology of this paper, the deductive approach is used basing on several methods such as dialectical materialism, description method, statistic method, forecasting, comparison, asking from the experts, analysis and interpreting, etc… The most important conclusions are the suitable strategies for Saigon Co.op Mart including: Market developing strategy, Competitive pricing strategy, Forward integration strategy, Strategy to retain talents. The data is collected from the company annual reports, journals, articles, published books and the internet. It is believed that these recommendations will play a strategically role for the growth of Saigon Co-op Mart in spite of some limitations which should be deal with in further researches.

In recent years, logistics have become one of the blooming economics field in Vietnam. In the age of globalization, the requirement in logistics and supply chain even bigger and many companies are attracted to this business. However, there are many level in range of the country such as: the way companies do business in the South compare to others areas, competition between foreign logistics companies and domestics companies. Also, because of the poor in service quality control makes the domestics companies/ corporations have disadvantage in the battle of sharing market. As research shows the cost of logistics accounted for almost 10% in the domestic product price and take for 40% in foreign product price. As matter of the fact that the domestics companies just meet 40% of market requirement. In case of development, Vietnam has many advantages to improve and develop the logistics industry, gain more money to flourish the national economy.

The current situation and problem in every organization is about how to have appropriate human resources management. Thus, the organization itself can achieve high productivity and attractiveness to the labor force. Based on this research, the author hopes to investigate specific organizations in the supermarket sector, such as the Saigon Cooperative or Coop Mart Saigon (Vietnam), to understand employees' views on organization's fairness and determination. Performance Assessment Employee Satisfaction Level (PA). In addition, this study investigated the relationship between PA satisfaction and employee turnover intentions, and whether their satisfaction affected their intention to leave the organization. The study used a face-to-face survey of 170 employees and obtained a 100% effective response rate. After analysis, the results show that there is a positive correlation between organizational justice and PA satisfaction, indicating that absolute importance of the highest score of interactive justice: the satisfaction of the staff. In addition, although employees seem to be satisfied with SPA, their willingness to leave is still high. Unfortunately, this article hopes to provide some insights and suggestions for further research and management of PA or PAS satisfaction or employee turnover intentions, as a source of advice for these related concepts.
