    Erosion and Nutrient Loss on Sloping Land under Intense Cultivation in Southern Vietnam

    GEOGRAPHICAL RESEARCH, Issue 1 2008
    NGUYEN VAN DE
    Abstract To help improve the well-being of the local people, a joint Vietnamese-UK team set out to establish a way of estimating soil and nutrient losses under different land management scenarios, using field data extrapolated through remote sensing and GIS, to obtain catchment-wide estimates of the impact of land cover change. Immigration from remote provinces to the Dong Phu District of Binh Phuóc Province, about 120 km north of Ho Chi Minh City, has led to disruption of soil surface stability on easily eroded clayey sandstones, creating rapid nutrient depletion that affects crop yields and siltation in the channel of the Rach Rat river downstream. The poor farmers of the areas see crop yields drop dramatically after two or three years of cultivation due to the fertility decline. Soil loss varies dramatically between wet season and dry season and with ground cover. Erosion bridge measurements showed a mean loss of 85.2 t ha,1 y,1 under cassava saplings with cashew nuts, 43.3 t ha,1 y,1 on uncultivated land and 41.7 t ha,1 y,1 under mature cassava. The rates of erosion were higher than those reported in many other parts of Vietnam, reflecting the high erodibility of the friable sandy soils on the steep side-slopes of the Rach Rat catchment. However, although the actual measurements provide better soil loss data than estimates based on the parameters of soil loss equations, a large number of measurement sites is needed to provide adequate coverage of the crop and slope combinations in this dissected terrain for good prediction using GIS and remote sensing.

    Comparison of updating techniques in transferability analysis of work trip mode choice models in developing countries

    JOURNAL OF ADVANCED TRANSPORTATION, Issue 2 2010
    Djoen San Santoso
    Abstract This study analyzes the performances of updating techniques in transferability of mode choice models in developing countries. A model specification, estimated in Ho Chi Minh City, was transferred to Phnom Penh. Naïve transfer and four updating methods associated with small sized samples were used in the transfer process and were evaluated based on statistical perspective and predictive ability. The study also illustrates the problems faced in model transferability development, due to the lack of available and suitable data in Phnom Penh. This lack is strongly related to different methods and structures applied in collecting the data. Simplified approaches to the difficulties are proposed in the study. The results show that updating ASCs, updating both ASCs and scale parameter, and use of combined transfer estimators all produce significant improvement, both statistically and in predictability, in updating the model. The last two methods have proven to be superior to the first method, owing to the inclusion of transfer bias considerations in the estimations. However, small data samples should not have large transfer bias when using combined transfer estimators. It is also concluded that naïvely transferring a model is not recommended, and Bayesian updating should be avoided when transfer bias exists. Copyright © 2010 John Wiley & Sons, Ltd. [source]


    Diversity of viruses associated with acute gastroenteritis in children hospitalized with diarrhea in Ho Chi Minh City, Vietnam

    JOURNAL OF MEDICAL VIROLOGY, Issue 5 2007
    Tuan Anh Nguyen
    Abstract A molecular epidemiological study on common diarrheal viruses was conducted in Ho Chi Minh City, Vietnam between October 2002 and September 2003. Fecal samples were collected from 1,010 hospitalized children with acute gastroenteritis. Those samples were screened for groups A, B, and C rotavirus, adenovirus, genogroups I and II norovirus (NoV), sapovirus (SaV), and human astrovirus (HAstV) by RT-multiplex PCR, and the positive specimens were characterized further by ELISA, nested PCR, or sequencing. Among the diarrheal viruses detected, group A rotavirus was the most common, with a proportion of 67.4%, whereas NoV GII, adenovirus, SaV, and HAstV were also found in 5.5, 3.2, 0.8, and 0.6%, respectively. It is noteworthy that the group C rotavirus was first reported in Vietnam, with a proportion of 0.5% in this study. Fifty-six of 1,010 (5.5%) samples were found positive with more than one viral agent, in which 25 samples contained both group A rotavirus and NoV GII. Group A rotavirus could be identified throughout year with the peaks in both the dry and rainy season, whereas other viruses prevailed mainly in the rainy season. G-typing for the group A rotavirus showed that genotype 1 was still the most prevailing (33.0%), but interestingly, serotype 9 was emergent and became the third most common rotavirus G-type in these samples (13.7%). The four most common G,P combinations globally, G1P[8], G2P[4], G3P[8], and G4P[8] were found in 46.8% of rotavirus-positive samples, and it is of interest that one unusual rotavirus G9P[19] strain was first detected in Vietnam. The majority of NoV strains belonged to GII/4, and SaV strains mainly clustered with the Manchester strain (GI/1). Twenty-seven out of 32 adenovirus strains were identified as serotype 41. All HAstVs belonged to genotype 1. The results indicated clearly the impact of viral agents causing gastroenteritis and the importance of vaccination against diarrhea in Vietnam. J. Med.

    The Limits of Authenticity in Vietnamese Consumer Markets

    AMERICAN ANTHROPOLOGIST, Issue 2 2006
    ELIZABETH F. VANN
    In this article, I address the saliency of the concept of "authenticity" in contexts of international law and anthropological inquiry. Using my research findings in Ho Chi Minh City (HCMC), Vietnam, I show that although Vietnamese shoppers distinguish between what they term real and fake goods, they do not share with foreign corporations and international trade organizations a preoccupation with product and brand authenticity. To make this point, I describe four types of goods,model goods, mimic goods, real goods, and fake goods,employed by shoppers in HCMC, and discuss why they have little in common with notions of "authenticity" and "ownership" inherent in international standards of intellectual property. I argue that these conceptual differences in the commercial sphere challenge claims about the universal applicability of intellectual property rights laws and also encourage anthropologists to ask whether authenticity is always a useful tool of cross-cultural understanding.

    On the back of a motorbike: Middle-class mobility in Ho Chi Minh City, Vietnam

    AMERICAN ETHNOLOGIST, Issue 1 2008
    ALLISON TRUITT
    ABSTRACT "Mobility" is a key concept in understanding processes of globalization and class formation. In this article, I examine motorbike mobility in Ho Chi Minh City and its role in reordering social stratification in urban Vietnam. In the years following trade liberalization, motorbikes emerged as exemplary symbols of purchasing power, displaying both monetized and motorized power. In response to the exponential increase in the number of motorbikes, Vietnamese state agencies inscribed streets with divisions to separate different classes of vehicles and regulate the flow of traffic. Motorbikes, I argue, elude attempts to regulate their movement precisely because they embody the very mobility promised by economic reforms.

    Rotavirus infection among infants with diarrhea in Vietnam

    PEDIATRICS INTERNATIONAL, Issue 4 2000
    Osamu Nishio
    Abstract Rotavirus was examined from diarrheal stool samples of 158 infants in rural area near Ho Chi Minh City, Vietnam, from 1994 to 1996. Group A rotavirus was detected in 50%. G1 and G4 were the predominant serotypes. G3 was not detected. The most predominant type changed from year to year. Rotavirus was found in all seasons, especially in winter and autumn. Infants younger than 2 years of age were those mostly infected and the virus was suspected to invade high concentration in this area. [source]


    Endobronchial foreign bodies in Vietnamese adults are related to eating habits

    RESPIROLOGY, Issue 3 2010
    Lan Huu NGUYEN
    ABSTRACT Background and objective: A high percentage of bronchoscopically extracted foreign bodies in Ho Chi Minh City were pits of the sapote fruit, a finding previously unreported. This paper presents a review of foreign body extractions, which identifies the substances found, documents the diagnostic pathway and draws attention to the specific aspiration risk of the sapote pit. Methods: The records of 100 consecutive adults who were found to have a bronchial foreign body during flexible bronchoscopy were reviewed. Results: In 83% of patients, the foreign body extraction was performed more than 2 weeks after the aspiration had occurred. In only 34% of patients was the diagnosis of an aspirated foreign body considered early in the patient's clinical course. The most frequent foreign bodies found were sapote pits (41%), followed by small bones (38%). Foreign bodies were lodged more frequently in the right bronchial tree (64%). In 98% of patients, the foreign bodies were successfully removed with the flexible scope. There was one postoperative death, which was not ascribed to the procedure. Conclusions: Physicians need to consider foreign body aspirations when evaluating patients with recurrent pneumonia, unexplained cough or atelectasis. Awareness of this problem might lead to public health measures that could reduce the incidence of these aspirations. [source]


    Vietnam's Civilizing Process and the Retreat from the Street: A Turtle's Eye View From Ho Chi Minh City

    CITY & SOCIETY, Issue 2 2009
    ERIK HARMS
    Abstract This paper documents the closing down of street life at the Turtle Lake café district in Ho Chi Minh City, Vietnam. Once a bustling area of outdoor activity where patrons would sit in outdoor cafés and turn their gaze towards the public activity of the street, the area has recently been cleared of street side cafés. Instead of looking outward toward the street, patrons now sit indoors in high-end cafes with darkened windows, their gazes directed inwards in a fashion that turns their backs on the street. The new direction of their gaze is linked to both state and popular language about the desire to build a new form of "urban civilization." In this paper, I show how the language of civilization, coupled with a new spatialized dialectic of seeing, shows a convergence between the disciplinary goals of the late socialist Vietnamese state and the interests of an emerging propertied class in urban Ho Chi Minh City. The logic of "civilization" thus unifies agendas heretofore seen as mutually opposed. [source]
