Nouvelle fran aise contemporaine et théories du genre
Pham Thi That
Synergies Pays Riverains du Mékong , 2010,
Abstract: La nouvelle fran aise contemporaine frappe par sa richesse et sa variété. Si bien qu’on se demande ce que c’est qu’une nouvelle. La diversité des notions théoriques formulées par des lexicographes, par des critiques et par des écrivains eux-mêmes montre qu’on ne peut définir avec rigueur ce genre littéraire :il existe toujours une certaine inadéquation entre la théorie et la pratique.

Pham Van Quang, Vo Thi Guong
Agricultural Sciences (AS) , 2011, DOI: 10.4236/as.2011.23049
Abstract: This study to examine soil fertility status was conducted on 10 citrus plantations in Hau Giang province within the Vietnamese Mekong Delta, Vietnam. Fruit trees are mostly grown on the raised beds to avoid annual flood with alluvial soil type. Soil sampling was done in the dry season of 2010 at two soil depths, for each raised bed. Development ages of raised beds were represented by two groups, young age group (≤ 30 years) and old age group (> 30 years). For chemical analysis, pH, organic matter, CEC, total nitrogen, NH4+, NO3– and exchangeable Ca, Mg and K were determined. The results showed that the pH (water) was strongly acid. The CEC was in average 19.2 cmol+.kg–1 in topsoil (0 - 20 cm depth) and 18.7 cmol+.kg–1 in subsoil (20 - 50 cm depth) for young age group. Similarly, the CEC was 16.7 cmol+.kg–1 in topsoil and 15.8 cmol+.kg–1 in subsoil for old age group. Organic matter on young age group (7.38 and 5.47% on average for topsoil and subsoil respectively) was significantly higher than that of old age group (5.20 and 3.81% on average for topsoil and subsoil respectively). Total nitrogen was not significantly different between the sites for the age groups of raised as well as the soil layers. Ammonium-N levels were excessive, and NO3--N levels were high. Potassium and Mg2+ were significantly different between age groups of raised beds and the same pattern between soil layers, while Ca2+ did not vary significantly. Potassium and Ca2+ levels were moderate, Mg2+ was high and P levels were very high. Soil fertility in the raised beds subjected to an adverse on plant growth and an imbalance in soil nutrients under low pH conditions. Loss of soil quality was exhibited in reduced organic matter with the aging of raised beds.

Abstract: Background To date, little is known about the initial spread and response to the 2009 pandemic of novel influenza A (“2009 H1N1”) in tropical countries. Here, we analyse the early progression of the epidemic from 26 May 2009 until the establishment of community transmission in the second half of July 2009 in Ho Chi Minh City (HCMC), Vietnam. In addition, we present detailed systematic viral clearance data on 292 isolated and treated patients and the first three cases of selection of resistant virus during treatment in Vietnam. Methods and Findings Data sources included all available health reports from the Ministry of Health and relevant health authorities as well as clinical and laboratory data from the first confirmed cases isolated at the Hospital for Tropical Diseases in HCMC. Extensive reverse transcription (RT)-PCR diagnostics on serial samples, viral culture, neuraminidase-inhibition testing, and sequencing were performed on a subset of 2009 H1N1 confirmed cases. Virological (PCR status, shedding) and epidemiological (incidence, isolation, discharge) data were combined to reconstruct the initial outbreak and the establishment of community transmission. From 27 April to 24 July 2009, approximately 760,000 passengers who entered HCMC on international flights were screened at the airport by a body temperature scan and symptom questionnaire. Approximately 0.15% of incoming passengers were intercepted, 200 of whom tested positive for 2009 H1N1 by RT-PCR. An additional 121 out of 169 nontravelers tested positive after self-reporting or contact tracing. These 321 patients spent 79% of their PCR-positive days in isolation; 60% of PCR-positive days were spent treated and in isolation. Influenza-like illness was noted in 61% of patients and no patients experienced pneumonia or severe outcomes. Viral clearance times were similar among patient groups with differing time intervals from illness onset to treatment, with estimated median clearance times between 2.6 and 2.8 d post-treatment for illness-to-treatment intervals of 1–4 d, and 2.0 d (95% confidence interval 1.5–2.5) when treatment was started on the first day of illness. Conclusions The patients described here represent a cross-section of infected individuals that were identified by temperature screening and symptom questionnaires at the airport, as well as mildly symptomatic to moderately ill patients who self-reported to hospitals. Data are observational and, although they are suggestive, it is not possible to be certain whether the containment efforts delayed community transmission in Vietnam.
An Investigation of Perceptions of Vietnamese Teachers and Students toward Cooperative Learning (CL)
Pham Thi Hong Thanh
International Education Studies , 2011, DOI: 10.5539/ies.v4n1p3
Abstract: The present study examined how cooperative learning (CL) is implemented in Vietnamese classrooms, how local teachers' and students' perceived this approach to learning, and what were the local barriers that hindered its implementation. Forty teachers and forty students from twenty Vietnamese colleges completed a questionnaire about CL and follow-up interviews were conducted with ten students and ten teachers on their perceptions of this practice. The results showed that CL has become a common and preferred method of instruction in Vietnam. However, the functions of CL were often not understood correctly because the teachers and students maintained that CL mainly helped the students remember information rather than develop a deep understanding of the text they were studying. Responses also revealed that CL was hindered by a number of local cultural and institutional barriers such as class size, curriculum coverage and workload division. Future research may need to identify strategies to correct mismatches between CL principles and local barriers so that this approach to learning becomes more adaptive to the local context.
The Roles of Teachers in Implementing Educational Innovation: The Case of Implementing Cooperative Learning in Vietnam
Pham Thi Hong Thanh
Asian Social Science , 2009, DOI: 10.5539/ass.v4n1p3
Abstract: Since the late 1990s there has been a top-down movement to reform teaching and learning approaches in Vietnam. An important component of this reform is to change the traditional teaching and learning approach into cooperative learning. However, cooperative learning has failed to make its impact on the current teaching and learning approach. This paper examines one of the most important constraints on the implementation of cooperative learning in Vietnam, namely, perceptions of Vietnamese teachers toward the roles and responsibilities of teachers in class. It argues that many principles of cooperative learning are in serious conflict with traditional perceptions of Vietnamese teachers regarding the nature of teaching and learning. Therefore, policymakers and educators need to take cautious steps when implementing such radical approaches in Vietnamese educational settings. If they want to obtain support from teachers, they cannot merely borrow the original version of the innovation. Rather, they need to take various modifications into consideration.

Low Carbon Economy (LCE) , 2014, DOI: 10.4236/lce.2014.53010
Abstract:

To process biomass energy successfully, it is necessary to incorporate a number of criteria that can be assessed either quantitatively or qualitatively for various biomass scenarios. It is also important to take into account the local people’s preferences and interests in the decision-making process. In this study, preferences of various stakeholders on rice husk use, such as urban households, rural households, rice mill owners, brick kiln owners, government officials, and scientists, were investigated using the Analytic Hierarchy Process. The results were incorporated with objective evaluation that was derived from Life Cycle Assessment. A holistic evaluation of rice-husk use scenarios was conducted. The results showed that rural households, rice mill owners, and brick kiln owners still want to use rice husk in conventional ways, while urban households, government officials, and scientists prefer to use rice husk with new technologies. The results reveal the aspects that each stakeholder thinks important and the conflicts between stakeholders. These can help government officials grasp the preferences of the local people which is important information for decision-making.

Productivity Growth, Technological Progress, and Efficiency Change in Vietnamese Manufacturing Industries: A Stochastic Frontier Approach  [PDF]
Nguyen Khac Minh, Pham Van Khanh, Nguyen Thi Minh, Nguyen Thi Phuong Anh
Open Journal of Statistics (OJS) , 2012, DOI: 10.4236/ojs.2012.22028
Abstract: This study applies a stochastic frontier production approach to decompose the sources of total productivity (TFP) growth into technical progress and changes in technical efficiency of 8057 firms in Vietnamese manufacturing industries during 2003-2007. Using both total manufacturing industry and sub-manufacturing industrial regressions, the analysis focuses on the trend of technological progress (TP) and technical efficiency change (TEC), and the role of productivity change in economic growth. According to the estimated results, the annual technical progress for the manufacturing industry and sub-manufacturing industries are calculated directly from the estimated parameters of the translog stochastic frontier production function by taking a partial derivative of output with respect to time t. The average technical changes in manufacturing industry and sub-manufacturing industries are positive, with an average technical change about 5.2%, 5.8%, 5.4%, 11.8%, 4.6%, 4.1%, 7.3%, 4.8%, 4.8% and 4.8% for total sample, food products & beverages, textile & wearing apparel, footwear, paper & products, industrial chemicals, rubber & plastic products, non- metallic mineral, basic & fabricated metal and other sub-industries, respectively. Total TFP in the manufacturing sector has grown at the annual rate of 0.052, although the rate of growth decreased continuously during the sample period. For the sub-industry estimates during the sample period, TFP grew fastest in the footwear sub-industry, with annual average growth rate of 11.8%, followed by the rubber & plastic products with a rate of 7.3%, and the food products & beverages with a rate of 5.8% per annum.

Open Journal of Social Sciences (JSS) , 2018, DOI: 10.4236/jss.2018.69013
Abstract: Love could be one of the factors affecting on human happiness. Love (love others) and narcissism (self-love) could have a special relationship. This study aims to analyze the relationship between Love, Subjective well-being, and Narcissism, taking into account some of the cultural characteristics of Vietnam. The survey was conducted on 543 people aged from 19 to 40 years (M = 27.8; SD = 6.5), included 369 women (67.5%), 251 married people (46%). Love was measured using the Sternberg Love Scale [11]; Subjective well-being were measured by the Mental Health Continuum—Short Form [15]; Agentic narcissism was measured by the Narcissistic Personality Inventory [6]. The marital status was included in the study for comparison purpose. The results showed that Love and Narcissism do not have the significant correlation, while Love and Narcissism were positively correlated to the Subjective well-being. These positive correlations were higher among the married people. On average, Narcissism of married people was lower, while Love and Subjective well-being of married people was higher than that of the unmarried people. The paper also discusses about the positive correlation between subjective well-being and narcissism, and the positive effect of marriage on love and happiness of Vietnamese people.

Health (Health) , 2012, DOI: 10.4236/health.2012.46048
Abstract: Background: Even though the number of research on tobacco in Vietnam has recently increased rapidly, there remains a lack of reporting on the pattern of quit smoking and its correlates. It is necessary to have scientific evidence on this issue to help the policy makers and the Public Health sector to have appropriate intervention program to enhance the smoke cessation smoke program and improve the health status of the smokers. This study aims to: (1) Describe the pattern of smoking cessation in Vietnam 2010. (2) Examine the association between smoking cessation with some associated factors in Vietnam 2010. Methods: Data used in this paper were obtained from the Global Adult Tobacco Survey (GATS) conducted in Vietnam in 2010. A total of 11,142 households were selected for this survey using a two-phase sampling design analogous to a three-stage stratified cluster sampling. Both descriptive and analytical statistical analyses were carried out. Multivariate logistic regression modeling was performed to examine the association between the patterns of quit daily; quit smoke; attempt to quit and intend to quit among smokers with relevant factors. Results: The prevalence of the different type of cessation among male and female were 23.3% and 28.6% for quit daily; 19.1% and 1.0% for quit; 55.6% and 44.4% for attempt to quit and 29.6% and 19.3% for intend to quit respectively. The prevalence of quit daily and quit increased with age whereas attempt to quit decreased with age. Prevalence of cessation was highest among the group who were asked about smoking tobacco by health care providers. Some determinants of quit daily and quit include age, area, and knowledge of illnesses caused by smoking. There was no association between attempt and intend to quit with any socio-characteristic except for area. People in rural area were 2.1 and 1.7 times more likely attempt to quit and intend to quit than those in urban area, respectively. Conclusion: The GATS Vietnam 2010 showed that the prevalence of cessation in Vietnam was low. Quit daily and quit had association with age, area, knowledge about the top three consequences of smoke. People in rural area were 2.1 and 1.7 times more likely attempt to quit and intend to quit than those in urban area, respectively.

Nguyen Xuan Hai, Pham Ngoc Tuan, Nguyen Nhi Dien, Dang Lanh, Tuong Thi Thu Huong, Pham Dinh Khang
Journal of Analytical Sciences, Methods and Instrumentation (JASMI) , 2013, DOI: 10.4236/jasmi.2013.33018
Abstract:

The coincidence technique and the coincidence spectroscopy have been developed and applied for over 40 years. Most of popular coincidence measurement systems were based on analog electronics techniques such as time to amplitude conversion (TAC) or logic selecting coincidence unit. The above-mentioned systems are relatively cumbersome and complicated to use. With the strong growth of digital electronics techniques and computational science, the coincidence measurement systems will be constructed simpler but more efficient with the sake of application. This article presents the design principle and signal processing of a simple two-channel coincidence system by a technique of digital signal processing (DSP) using Field Programmable Gate Arrays (FPGA) devices at Nuclear Research Institute (NRI), Dalat.
