Equitable, Quality Education for Ethnic Minority Students? A Case of "Positive Deviance" in Vietnam
Vietnam has achieved near-universal access to compulsory schooling over the past two decades. However, inequalities between ethnic majority and minority students are stark at post-compulsory levels, where progression is selective based on academic criteria and ability to pay. In this article, we adopt a mixed-methods approach to examine quality and equity for ethnic minority students in upper secondary education. Across five provinces, we find that ethnic minority students attend “less effective” upper secondary schools than ethnic majority students. However, an in-depth case study of an ethnic minority boarding school in Lao Cai province provides an example of positive deviance. Guided by a targeted affirmative action policy, the provincial government invests a relatively high level of resources to provide fee-free, high-quality schooling for gifted ethnic minority students. We consider the extent to which such policies can redress socioeconomic inequalities in Vietnam, and wider lessons for creating more equitable education systems
Enterovirus D68 in Viet Nam (2009-2015)
Background: Since 1962, enterovirus D68 (EV-D68) has been implicated in multiple outbreaks and sporadic cases of respiratory infection worldwide, especially in the USA and Europe with an increasing frequency between 2010 and 2014. We describe the detection, associated clinical features and molecular characterization of EV-D68 in central and southern Viet Nam between 2009 and 2015.
Methods: Enterovirus/rhinovirus PCR positive respiratory or CSF samples taken from children and adults with respiratory/central nervous system infections in Viet Nam were tested by an EV-D68 specific PCR. The included samples were derived from 3 different observational studies conducted at referral hospitals across central and southern Viet Nam 2009 2015. Whole-genome sequencing was carried out using a MiSeq based approach. Phylogenetic reconstruction and estimation of evolutionary rate and recombination were carried out in BEAST and Recombination Detection Program, respectively.
Results: EV-D68 was detected in 21/625 (3.4%) enterovirus/rhinovirus PCR positive respiratory samples but in none of the 15 CSF. All the EV-D68 patients were young children (age range: 11.8 – 24.5 months) and had moderate respiratory infections. Phylogenetic analysis suggested that the Vietnamese sequences clustered with those from Asian countries, of which 9 fell in the B1 clade, and the remaining sequence was identified within the A2 clade. One intra sub-clade recombination event was detected, representing the second reported recombination within EV-D68. The evolutionary rate of EV-D68 was estimated to be 5.12E -3 substitutions/site/year. Phylogenetic analysis indicated that the virus was imported into Viet Nam in 2008.
Conclusions: We have demonstrated for the first time EV-D68 has been circulating at low levels in Viet Nam since 2008, associated with moderate acute respiratory infection in children. EV-D68 in Viet Nam is most closely related to Asian viruses, and clusters separately from recent US and European viruses that were suggested to be associated with acute flaccid paralysis
Gender, agency, and poverty: children’s everyday experiences in Andhra Pradesh and Vietnam
‘Children’s agency’ and ‘children as social actors’ have become taken for granted in much social science research (James 2009). In studies on childhood, agency has been accepted as a universal feature of what it means to be a child, and in international development, ‘children’s participation’ is an increasingly accepted principle (Vandenbroeck and Bouverne-De Bie 2006). In development, the notion of ‘empowerment’ suggests that power is something that can be bestowed on individuals or groups. This chapter will argue that power and agency are multidimensional and deeply social, including the power and agency of children (Attree 2006; Redmond 2009; Jeffrey 2012). Grounding analysis in children’s narratives of everyday life, the chapter asks what ‘agency’ means for children who grow up in poverty, and whether there are different kinds of agency, particularly for short-term and long-term ends.</p

Fine-scale population structure of Accumulibacter phosphatis in enhanced biological phosphorus removal sludge
To investigate the diversities of Accumulibacter phosphatis and its polyhydroxyalkanoate (PHA) synthase gene (phaC) in enhanced biological phosphorus removal (EBPR) sludge, an acetate-fed sequencing batch reactor was operated. Analysis of microbial communities using fluorescence in situ hybridization and 16S rRNA gene clone libraries showed that the population of Accumulibacter phosphatis in the EBPR sludge comprised more than 50% of total bacteria, and was clearly divided into two subgroups with about 97.5% sequence identity of the 16S rRNA genes. PAO phaC primers targeting the phaC genes of Accumulibacter phosphatis were designed and applied to retrieve fragments of putative phaC homologs of Accumulibacter phosphatis from EBPR sludge. PAO phaC primers targeting G(1PAO), G(2PAO), and G(3PAO) groups produced PCR amplicons successfully; the resulting sequences of the phaC gene homologs were diverse, and were distantly related to metagenomic phaC sequences of Accumulibacter phosphatis with 75-98% DNA sequence identities. Degenerate NPAO (non-PAO) phaC primers targeting phaC genes of non-Accumulibacter phosphatis bacteria were also designed and applied to the EBPR sludge. Twenty-four phaC homologs retrieved from NPAO phaC primers were different from the phaC gene homologs derived from Accumulibacter phosphatis, which suggests that the PAO phaC primers were specific for the amplification of phaC gene homologs of Accumulibacter phosphatis, and the putative phaC gene homologs by PAO phaC primers were derived from Accumulibacter phosphatis in the EBPR sludge. Among 24 phaC homologs, a phaC homolog (G1NPAO-2), which was dominant in the NPAO phaC clone library, showed the strongest signal in slot hybridization and shared approximately 60% nucleotide identity with the G(4PAO) group of Accumulibacter phosphatis, which suggests that G1NPAO-2 might be derived from Accumulibacter phosphatis. In conclusion, analyses of the 16S rRNA and phaC genes showed that Accumulibacter phosphatis might be phylogenetically and metabolically diverse.X114sciescopuskc
Primary care influenza‐like illness surveillance in Ho Chi Minh City, Vietnam 2013‐2015
Background Year-round transmission of influenza has been detected in Vietnam through both national surveillance and other epidemiological studies. Understanding the demographic and clinical features of influenza-like-illness (ILI) presenting to primary care in urban Vietnam is vital to understand these transmission dynamics. Methods A prospective, observational study of patients with ILI in Ho Chi Minh City, Vietnam was conducted between August 2013 and November 2015 in a mix of public and private primary care settings. Molecular testing for Influenza A & B and 12 other respiratory viruses was performed. Results 1152 ILI patients were recruited. 322 and 136 subjects tested positive for influenza A and B, respectively. 193 subjects tested positive for another respiratory virus; most commonly rhinovirus and parainfluenza virus 3. Influenza was detected in 81% of the 116 study weeks. Three peaks of influenza activity were detected; an H3N2 peak April-June 2014, an influenza B peak July-December 2014, and a mixed H3N2 and H1N1 peak March-September 2015. Subjects recruited from private clinics were more likely to have higher income, and to have reported previous influenza vaccination. Antibiotic use was common (50.3%) despite limited evidence of bacterial infection. Conclusion Influenza in southern Vietnam has complex transmission dynamics including periods of intense influenza activity of alternating types and subtypes. Broadening surveillance from hospital to the community in tropical settings is feasible and a valuable for improving our understanding of the global spread and evolution of the virus.</p
