Our previous studies have demonstrated the inadequate nutritional status of Vietnamese female marriage immigrants in Korea. Major possible reasons include food insecurity due to economic problems as well as a lack of adjustment to unfamiliar Korean foods and limited access to Vietnamese foods; however, no study has investigated food insecurity among such intermarried couples. This study was performed to investigate the prevalence of food insecurity in Korean-husband-Vietnamese-wife couples and to determine whether they exhibit an intrahousehold discrepancy regarding food insecurity. A cross-sectional analysis of the Cohort of Intermarried Women in Korea study was performed with 84 intermarried couples. Among the 84 Vietnamese immigrants, 48.8% and 41.7% had food insecurity due to economic problems and a lack of foods appealing to their appetite, respectively. There was a marked discrepancy in reporting food insecurity between Vietnamese wives (22.6-38.1%) and their Korean husbands (6.0-15.5%). Vietnamese wives were five and two times more food-insecure due to economic problems and no foods appealing to their appetite, respectively, than their Korean spouses. A follow-up study is needed to investigate the causes of this discrepancy and ways of reducing food insecurity among female marriage immigrants living in low-income, rural communities.

This study investigates the ‘marginal effects of employment’ with respect to real output and capital in South Africa, using annual data covering the period 1946-2015.  It estimates the responsiveness of employment to real output growth and capital, employing the short and long-run dynamic interactions between these variables via the application of the VAR/VECM Joh...

Cross-Border Brides: Vietnamese Wives, Chinese Husbands in a Border-Area Fishing Village

Directory of Open Access Journals (Sweden)

Nguyễn Thị Phương Châm

2014-06-01

Full Text Available This article traces the lives of a group of Vietnamese women driven by poverty and loss of marriageability to cross the border into China to marry men from the fishing village of Wanwei. Wanwei’s location, only 25 kilometers from the border with Vietnam, enables these women to make fairly regular trips back to their native villages to visit their birth families. Yet, despite the fact that they now live in a designated Jing (ethnic Vietnamese village, where a significant proportion of the population shares their ethnicity, their illegal residential status and recent arrival excludes them from the community of villagers who claim descent from Vietnamese immigrants in the sixteenth century. Despite the hardships these women face as a result of continuing poverty, lack of emotional intimacy in their marriages, and marginal social status, few see themselves as victims of human trafficking. Instead, most take pride in their agency and achievements.

Identifying the determinants of South Africa’s extensive and intensive trade margins: A gravity model approach

Directory of Open Access Journals (Sweden)

Marianne Matthee

2017-03-01

Full Text Available Background: The significance of the paper is twofold. Firstly, it adds to the small but growing body of literature focusing on the decomposition of South Africa’s export growth. Secondly, it identifies the determinants of the intensive and extensive margins of South Africa’s exports – a topic that (as far as the authors are concerned has not been explored before. Aim: This paper aims to investigate a wide range of market access determinants that affect South Africa’s export growth along the intensive and extensive margins. Setting: Export diversification has been identified as one of the critical pillars of South Africa’s much-hoped-for economic revival. Although recent years have seen the country’s export product mix evolving, there is still insufficient diversification into new markets with high value-added products. This is putting a damper on export performance as a whole and, in turn, hindering South Africa’s economic growth. Methods: A Heckman selection gravity model is applied using highly disaggregated data. The first stage of the process revealed the factors affecting the probability of South Africa exporting to a particular destination (extensive margin. The second stage, which modelled trade flows, revealed the variables that affect export volumes (intensive margin. Results: The results showed that South Africa’s export product mix is relatively varied, but the number of export markets is limited. In terms of the extensive margin (or the probability of exporting, economic variables such as the importing country’s GDP and population have a positive impact on firms’ decision to export. Other factors affecting the extensive margin are distance to the market (negative impact, cultural or language fit (positive impact, presence of a South African embassy abroad (positive impact, existing free trade agreement with Southern African Development Community (positive impact and trade regulations and costs (negative

Preferential mantle lithospheric extension under the South China margin

International Nuclear Information System (INIS)

Clift, P.; Jian Lin

2001-01-01

Continental rifting in the South China Sea culminated in seafloor spreading at ∼ 30Ma (Late Oligocene). The basin and associated margins form a classic example of break-up in a relatively juvenile arc crust environment. In this study, we documented the timing, distribution and amount of extension in the crust and mantle lithosphere on the South China Margin during this process. Applying a one-dimensional backstripping modeling technique to drilling data from the Pearl River Mouth Basin (PRMB) and Beibu Gulf Basin, we calculated subsidence rates of the wells and examined the timing and amount of extension. Our results show that extension of the crust exceeded that in the mantle lithosphere under the South China Shelf, but that the two varied in phase, suggesting depth-dependent extension rather than a lithospheric-scale detachment. Estimates of total crustal extension derived in this way are similar to those measured by seismic refraction, indicating that isostatic compensation is close to being local. Extension in the Beibu Gulf appears to be more uniform with depth, a difference that we attribute to the different style of strain accommodation during continental break-up compared to intra-continental rifting. Extension in PRMB and South China slope continues for ∼ 5m.y. after the onset of seafloor spreading due to the weakness of the continental lithosphere. The timing of major extension is broadly mid-late Eocene to late Oligocene (∼ 45-25Ma), but is impossible to correlate in detail with poorly dated strike-slip deformation in the Red River Fault Zone.

Vietnamese Document Representation and Classification

Science.gov (United States)

Nguyen, Giang-Son; Gao, Xiaoying; Andreae, Peter

Vietnamese is very different from English and little research has been done on Vietnamese document classification, or indeed, on any kind of Vietnamese language processing, and only a few small corpora are available for research. We created a large Vietnamese text corpus with about 18000 documents, and manually classified them based on different criteria such as topics and styles, giving several classification tasks of different difficulty levels. This paper introduces a new syllable-based document representation at the morphological level of the language for efficient classification. We tested the representation on our corpus with different classification tasks using six classification algorithms and two feature selection techniques. Our experiments show that the new representation is effective for Vietnamese categorization, and suggest that best performance can be achieved using syllable-pair document representation, an SVM with a polynomial kernel as the learning algorithm, and using Information gain and an external dictionary for feature selection.

Introduction: Swedish furniture companies have been quite successful in many parts of the world recently, with IKEA being a famous example of that. Meanwhile, Vietnam has one of the fastest-growing economies in South East Asia. However, there has not been any Swedish furniture company established on the Vietnamese market so far. Therefore, it would be useful to see if the Vietnamese furniture consumers would appreciate Swedish furniture, in order to analyze whether Swedish furniture companies...

Cross-Linguistic Analysis of Vietnamese and English with Implications for Vietnamese Language Acquisition and Maintenance in the United States

Directory of Open Access Journals (Sweden)

Giang Tang

2007-01-01

Full Text Available Two overall goals of this paper are a to provide a linguistic basis for promoting first language maintenance of Vietnamese in a larger United States context and b to stimulate future research in language acquisition of Vietnamese-English speakers. This paper is divided into three sections. Section 1 discusses previous studies on first language (L1 maintenance among Vietnamese Americans. Section 2 presents a cross-linguistic comparison of Vietnamese and English across speech-sound, word, and grammatical language levels. A cross-linguistic analysis may help educators better understand speaking patterns of Vietnamese American students. Based on this cross-linguistic comparison, Section 3 presents potential bi-directional interactions between Vietnamese and English within an individual speaker. These predictions are intended to provide a framework for future empirical studies related to bilingual development.

Analysis of late Jurassic-recent paleomagnetic data from active plate margins of South America

Science.gov (United States)

Beck, Myrl E.

Paleomagnetic results for rocks of late Mesozoic and Cenozoic age from South America are analyzed and interpreted. Emphasis is placed on the active margins of the continent. Some important conclusions are reached, with varying degrees of certainty: (1) The reference APW path for stable South America is fairly well defined for the Late Jurassic and Cretaceous, and is not much different from the present rotation axis. (2) The so-called "Bolivian orocline" involved counterclockwise rotations in Peru and northernmost Chile and clockwise rotations in Chile south of about latitude 18.5S. These rotations probably are a result of in situ small-block rotations in response to shear, not actual oroclinal bending. (3) The Bonaire block of northern Venezuela and Colombia has been rotated clockwise relative to the stable interior of South America by about 90°. It also seems to have drifted northward relative to the craton by as much as 1600 km. It probably represents a true accreted terrane, one of very few recognized in South America so far. (4) The "Magellanes orocline" at the southern tip of South America apparently involves some counterclockwise rotation of paleomagnetic vectors, but this too is probably the result of distributed shear. (5) Tectonic processes have very thoroughly "rearranged" the rocks making up the active margins of South America. "Rearrange" here denotes displacement of crustal blocks relative to their surroundings, without significant internal deformation By analogy with North America "rearrangement" might entail in situ block rotation, translation of crustal blocks along the continental margin, and accretion of exotic "tectonostratigraphic terranes". However, in western South America "rearrangement" seems to have consisted dominantly of block rotations that were essentially in situ. For the parts of the Andes investigated so far, late Mesozoic and Cenozoic accretion of exotic terranes and large-scale translation of crustal slivers, as found in western

Compared to white women, lower areal bone mineral density (aBMD) in middle-aged Vietnamese immigrants is due to reduced trabecular volumetric bone mineral density (vBMD), which in turn is associated with greater trabecular separation along with lower estrogen levels. The epidemiology of osteoporosis in Asian populations is still poorly known, but we previously found a deficit in lumbar spine aBMD among postmenopausal Southeast Asian women, compared to white women, that persisted after correction for bone size. This issue was revisited using more sophisticated imaging techniques. Twenty Vietnamese immigrants (age, 44-79 years) were compared to 162 same-aged white women with respect to aBMD at the hip, spine and wrist, vBMD at the hip and spine by quantitative computed tomography and vBMD and bone microstructure at the ultradistal radius by high-resolution pQCT. Bone turnover and sex steroid levels were assessed in a subset (20 Vietnamese and 40 white women). The aBMD was lower at all sites among the Vietnamese women, but femoral neck vBMD did not differ from middle-aged white women. Significant differences in lumbar spine and ultradistal radius vBMD in the Vietnamese immigrants were due to lower trabecular vBMD, which was associated with increased trabecular separation. Bone resorption was elevated and bone formation depressed among the Vietnamese immigrants, although trends were not statistically significant. Serum estradiol was positively associated with trabecular vBMD in the Vietnamese women, but their estrogen levels were dramatically lower compared to white women. Although reported discrepancies in aBMD among Asian women are mainly an artifact of smaller bone size, we identified a specific deficit in the trabecular bone among a sample of Vietnamese immigrants that may be related to low estrogen levels and which needs further study.

A Salmonella Typhimurium outbreak linked to Vietnamese bread rolls in South Western Sydney, Australia, 2015

2017-06-01

Full Text Available Introduction: In September 2015, the South Western Sydney (SWS Public Health Unit was notified of a cluster of Salmonella Typhimurium (STm cases with a common multiple-locus variable-number tandem repeats analysis (MLVA pattern. An investigation was conducted to identify a source and contain the outbreak. Methods: The cluster was initially identified through routine geographic information system cluster scanning applied to the New South Wales Notifiable Conditions Management System. Additional cases were identified through a complaint to local council about a bakery. The bakery was inspected and 48 environmental and food swabs were collected for analysis. Results: A total of 26 suspected cases were identified, of which 14 were interviewed. STm MLVA type 3-16-9-11-523 was identified in 19 of 26 case stool specimens. Most cases (12/14 consumed bread rolls containing pork or chicken with chicken liver pâté and raw egg mayonnaise filling. Five cases identified a common bakery exposure. Environmental and food samples from the bakery isolated STm with an identical MLVA pattern. Discussion: An STm cluster in SWS was investigated and found to be linked to Vietnamese bread rolls containing pork or chicken with chicken liver pâté and raw egg mayonnaise filling. Confirmation of a distinct MLVA pattern among STm isolates from clinical, food and environmental samples provided evidence to establish an epidemiological link between the cases and the implicated premises and informed public health action to contain the outbreak.

Reproductive tract infections (RTIs) are the cause of severe gynecological and maternal morbidity in India. In marginalized communities, women persevere quietly when faced with a culturally sensitive health issue such as an RTI. To hypothesize on the differential health behavior and low levels of reported incidents among women living in marginalized communities, we undertake an exploratory study in a coastal fishermen community in South India. We identify barriers influencing decisions to seek curative and preventive medical care. Public health practitioners and social workers may find our recommendations relevant for addressing health issues in marginalized communities.

Initiation of Extension in South China Continental Margin during the Active-Passive Margin Transition: Thermochronological and Kinematic Constraints

Science.gov (United States)

Zuo, X.; Chan, L. S.

2015-12-01

The South China continental margin is characterized by a widespread magmatic belt, prominent NE-striking faults and numerous rifted basins filled by Cretaceous-Eocene sediments. The geology denotes a transition from active to passive margin, which led to rapid modifications of crustal stress configuration and reactivation of older faults in this area. Our zircon fission-track data in this region show two episodes of exhumation: The first episode, occurring during 170-120Ma, affected local parts of the Nanling Range. The second episode, a more regional exhumation event, occurred during 115-70Ma, including the Yunkai Terrane and the Nanling Range. Numerical geodynamic modeling was conducted to simulate the subduction between the paleo-Pacific plate and the South China Block. The modeling results could explain the fact that exhumation of the granite-dominant Nanling Range occurred earlier than that of the gneiss-dominant Yunkai Terrane. In addition to the difference in rock types, the heat from Jurassic-Early Cretaceous magmatism in Nanling may have softened the upper crust, causing the area to exhume more readily than Yunkai. Numerical modeling results also indicate that (1) high lithospheric geothermal gradient, high slab dip angle and low convergence velocity favor the reversal of crustal stress state from compression to extension in the upper continental plate; (2) late Mesozoic magmatism in South China was probably caused by a slab roll-back; and (3) crustal extension could have occurred prior to the cessation of plate subduction. The inversion of stress regime in the continental crust from compression to crustal extension imply that the Late Cretaceous-early Paleogene red-bed basins in South China could have formed during the late stage of the subduction, accounting for the occurrence of volcanic events in some sedimentary basins. We propose that the rifting started as early as Late Cretaceous, probably before the cessation of subduction process.

Consonants, vowels and tones across Vietnamese dialects.

Vietnamese is spoken by over 89 million people in Vietnam and it is one of the most commonly spoken languages other than English in the US, Canada and Australia. This study defines between one and nine different dialects of Vietnamese spoken in Vietnam. In Vietnamese schools, children learn Standard Vietnamese which is based on the northern dialect; however, if they live in other regions they may speak a different dialect at home. This paper describes the differences between the consonants, semivowels, vowels, diphthongs and tones for four dialects: Standard, northern, central and southern Vietnamese. The number and type of initial consonants differs per dialect (i.e. Standard = 23, northern = 20, central = 23, southern = 21). For example, the letter "r" is pronounced in the Standard and central dialects as the retroflex /ʐ/, northern dialect as the voiced alveolar fricative /z/ or the trilled /r/ and in the southern dialect as the voiced velar fricative /ɣ/. Additionally, the letter "v" is pronounced in the Standard, northern and central dialects as the voiced bilabial fricative /v/, the southern dialect as the voiced palatal approximant /j/ and in the lower northern dialect (Ninh Binh) as the voiceless bilabial fricative /f/. Similarly, the number of final consonants differs per dialect (i.e. Standard = 6, northern = 10, central = 10, southern = 8). Finally, the number and type of tones differs per dialect (i.e. Standard = 6, northern = 6, central = 5, southern = 5). Understanding differences between Vietnamese dialects is important so that speech-language pathologists and educators provide appropriate services to people who speak Vietnamese.

A syntactic component for Vietnamese language processing

Directory of Open Access Journals (Sweden)

Phuong Le-Hong

2015-06-01

Full Text Available This paper presents the development of a syntactic component for the Vietnamese language. We first discuss the construction of a lexicalized tree-adjoining grammar using an automatic extraction approach. We then present the construction and evaluation of a deep syntactic parser based on the extracted grammar. This is a complete system integrating necessary tools to process Vietnamese text, which permits to take as input raw texts and produce syntactic structures. A dependency annotation scheme for Vietnamese and an algorithm for extracting dependency structures from derivation trees are also proposed. At present, this is the first Vietnamese parsing system capable of producing both constituency and dependency analyses with encouraging performances: 69.33% and 73.21% for constituency and dependency analysis accuracy, respectively. The parser also compares favourably to a statistical parser which is trained and tested on the same data sets.

Little is known about the relationship between traumatic head injury (THI) and psychiatric morbidity in torture survivors. We examine the relationship between THI and depression, PTSD, post-concussive syndrome (PCS), disability and poor health status in Vietnamese ex-political detainees who survived incarceration in Vietnamese re-education camps. A community sample of ex-political detainees (n=337) and a non-THI, non-ex-detainee comparison group (n=82) were surveyed. Seventy-eight percent of the ex-political detainees had experienced THI; 90.6% of the ex-political detainees and 3.6% of the comparison group had experienced 7 or more trauma events. Depression and PTSD were greater in ex-detainees than in the comparison group (40.9% vs 23.2% and 13.4% vs 0%). Dose-effect relationships for THI and trauma/torture in the ex-political detainee group were significant. Logistic regression in the pooled sample of ex-detainees and the comparison group confirmed the independent impact of THI from trauma/torture on psychiatric morbidity (OR for PTSD=22.4; 95% CI: 3.0-165.8). These results demonstrate important effects of THI on depression and PTSD in Vietnamese ex-detainees who have survived torture. Copyright © 2014 Elsevier Inc. All rights reserved.

Crustal structure and inferred extension mode in the northern margin of the South China Sea

Gao, J.; Wu, S.; McIntosh, K. D.; Mi, L.; Spence, G.

2016-12-01

Combining multi-channel seismic reflection and satellite gravity data, this study has investigated the crustal structure and magmatic activities of the northern South China Sea (SCS) margin. Results show that a broad continent-ocean transition zone (COT) with more than 140 km wide is characterized by extensive igneous intrusion/extrusion and hyper-extended continental crust in the northeastern SCS margin, a broader COT with 220-265 km wide is characterized by crustal thinning, rift depression, structural highs with igneous rock and perhaps a volcanic zone or a zone of tilted fault blocks at the distal edge in the mid-northern SCS margin, and a narrow COT with 65 km wide bounded seawards by a volcanic buried seamount is characterized by extremely hyper-extended continental crust in the northwestern SCS margin, where the remnant crust with less than 3 km thick is bounded by basin-bounding faults corresponding to an aborted rift below the Xisha Trough with a sub-parallel fossil ridge in the adjacent Northwest Sub-basin. Results from gravity modeling and seismic refraction data show that a high velocity layer (HVL) is present in the outer shelf and slope below extended continental crust in the eastern portion of the northern SCS margin and is thickest (up to 10 km) in the Dongsha Uplift where the HVL gradually thins to east and west below the lower slope and finally terminates at the Manila Trench and Baiyun sag of the Pearl River Mouth Basin. The magmatic intrusions/extrusions and HVL may be related to partial melting caused by decompression of passive, upwelling asthenosphere which resulted primarily in post-rifting underplating and magmatic emplacement or modification of the crust. The northern SCS margin is closer to those of the magma-poor margins than those of volcanic margins, but the aborted rift near the northwestern continental margin shows that there may be no obvious detachment fault like that in the Iberia-Newfoundland type margin.

Full Text Available Abstract Background In Vietnam the blackwater fever syndrome (BWF has been associated with malaria infection, quinine ingestion and G6PD deficiency. The G6PD variants within the Vietnamese Kinh contributing to the disease risk in this population, and more generally to haemoglobinuria, are currently unknown. Method Eighty-two haemoglobinuria patients and 524 healthy controls were screened for G6PD deficiency using either the methylene blue reduction test, the G-6-PDH kit or the micro-methaemoglobin reduction test. The G6PD gene variants were screened using SSCP combined with DNA sequencing in 82 patients with haemoglobinuria, and in 59 healthy controls found to be G6PD deficient. Results This study confirmed that G6PD deficiency is strongly associated with haemoglobinuria (OR = 15, 95% CI [7.7 to 28.9], P G6PD variants were identified in the Vietnamese population, of which two are novel (Vietnam1 [Glu3Lys] and Vietnam2 [Phe66Cys]. G6PD Viangchan [Val291Met], common throughout south-east Asia, accounted for 77% of the variants detected and was significantly associated with haemoglobinuria within G6PD-deficient ethnic Kinh Vietnamese (OR = 5.8 95% CI [114-55.4], P = 0.022. Conclusion The primary frequency of several G6PD mutations, including novel mutations, in the Vietnamese Kinh population are reported and the contribution of G6PD mutations to the development of haemoglobinuria are investigated.

In healthy Vietnamese children the respiratory resistance has been suggested to be similar at 110 cm height but larger at 130 cm when compared with data in Caucasians from the literature, suggesting smaller airways in older Vietnamese children (Vu et al., 2008). The hypothesis tested here is whether the difference in airway resistance remains consistent throughout growth, and if it is larger in adult Vietnamese than in Caucasians. Airway resistance and Functional Residual Capacity were measured in healthy young Caucasian and Vietnamese adults in their respective native country using identical equipment and protocols. Ninety five subjects in Vietnam (60 males) and 101 in France (41 males) were recruited. Airway resistance was significantly larger in Vietnamese than in Caucasians and in females than in males, consistent with difference in body dimensions. Specific airway resistance however was not different by ethnicity or gender. The findings do not support the hypothesis that airway size at adult age - once normalized for lung volume - differs between Vietnamese and Caucasians. Copyright © 2015 Elsevier B.V.

The Posttraumatic Stress Disorder Interview for Vietnamese Refugees (PTSD-IVR) was created specifically to assess for the presence of current and lifetime history of premigration, migration, encampment, and postmigration traumas in Vietnamese refugees. The purpose of the present study was to describe the development of and investigate the interrater and test-retest reliability of the PTSD-IVR and its validity in relation to the diagnoses obtained from the Longitudinal, Expert, and All Data (LEAD; Spitzer, 1983) standard. Clinicians conducted the diagnosis process with 127 Vietnamese refugees using the LEAD standard and the PTSD-IVR. Assessment of the reliability and validity of the PTSD-IVR yielded good to excellent AUC (area under the receiver operating characteristic curve; .86, .87) and κ values (.66, .74) indicating the reliability of the PTSD-IVR and the agreement between the LEAD procedure and the PTSD-IVR. The results of the present study suggest that the PTSD-IVR performs successfully as a diagnostic instrument specifically created for Vietnamese refugees in their native language.

Tobacco smoking is one of the most significant modifiable behavioral health risk factors worldwide. Although smoking rates in some high-income countries (HIC) have declined, rates in many low-and-middle-income countries (LMIC) remain high. Adolescence is a key developmental risk period for smoking initiation. Research indicates that a major adolescent risk factor for tobacco smoking is antisocial deviance, which includes such behaviors as aggression, risk-taking, and rule-breaking. The linkages between antisocial deviance and smoking suggest that these behaviors and their underlying attitudes can be important targets for smoking prevention programs, but for public health efficiency it is important to target the components of antisocial deviance most closely linked smoking. However, although 80% of smokers live in LMIC, most relevant research has been conducted in HIC and its applicability to LMIC is unclear, given cultural differences between many HIC and LMIC. The purpose of the present study was to assess cross-cultural variations in relations among components of antisocial deviance and self-reported tobacco smoking among 2,724 10th and 11th grade Vietnamese, Vietnamese-American, and European-American students. Within the combined sample the relation between self-reported smoking and overall antisocial deviance was β = 0.33. However, the component of antisocial deviance most strongly related to smoking varied across groups, with Risk-taking most strongly related to smoking for Vietnamese-American (β = 0.37) and Vietnamese (β = 0.36) adolescents, and Rule-breaking Behavior most strongly related to smoking for European-American (β = 0.51) adolescents. These and other findings suggest the possible importance of culturally-tailored foci for smoking prevention programs emphasizing different aspects of antisocial deviance.

This study identified, digitally recorded, edited and evaluated 89 bisyllabic Vietnamese words with the goal of identifying homogeneous words that could be used to measure the speech recognition threshold (SRT) in native talkers of Vietnamese. Native male and female talker productions of 89 Vietnamese bisyllabic words were recorded, edited and then presented at intensities ranging from -10 to 20 dBHL. Logistic regression was used to identify the best words for measuring the SRT. Forty-eight words were selected and digitally edited to have 50% intelligibility at a level equal to the mean pure-tone average (PTA) for normally hearing participants (5.2 dBHL). Twenty normally hearing native Vietnamese participants listened to and repeated bisyllabic Vietnamese words at intensities ranging from -10 to 20 dBHL. A total of 48 male and female talker recordings of bisyllabic words with steep psychometric functions (>9.0%/dB) were chosen for the final bisyllabic SRT list. Only words homogeneous with respect to threshold audibility with steep psychometric function slopes were chosen for the final list. Digital recordings of bisyllabic Vietnamese words are now available for use in measuring the SRT for patients whose native language is Vietnamese.

To assess the proportions of glaucoma types and clinical characteristics in Vietnamese Americans in a single-center, retrospective study. Medical charts of Vietnamese-American patients who visited a single private practice in Northern California from 1998-2007 were reviewed. The main outcome measures included the distribution and characteristics of glaucoma types, and clinical parameters associated with the presence of various glaucomas. Data from 2247 patients aged 18-98 years were reviewed. Glaucoma was determined for 305 patients (13.6%). Among this group, 54.8% had primary open-angle glaucoma (POAG), 26.9% had primary angle-closure glaucoma (PACG), 13.4% had mixed mechanism glaucoma (MMG), and 4.9% had secondary glaucoma. In the MMG group (41 patients), 27 patients who initially had open angles developed narrow angles and underwent laser peripheral iridotomy (LPI) with a mean follow up of 6.4 years from the time of iridotomy. The other 13 patients had glaucoma progression with open angles after LPI. One POAG patient had neovascular glaucoma due to retinal vein occlusion several years later. Compared to the PACG group, the MMG group had significantly lower baseline intraocular pressure (25.0 vs. 20.2 mmHg, p = 0.007) but with no difference in biometry. POAG is the major type of glaucoma in this clinic-based Vietnamese population. However, Vietnamese appear to have a relatively higher proportion of PACG than Caucasians and those of African descent. It is recommended that gonioscopy be part of the regular eye check-up for adult Vietnamese patients.

Structural inversion in the northern South China Sea continental margin and its tectonic implications

Directory of Open Access Journals (Sweden)

Chin-Da Huang

2017-01-01

Full Text Available The northern South China Sea (SCS continental margin was proposed to be an active margin during the Mesozoic. However, only a few papers discussed the Mesozoic structural evolution in this region. Here, we provide information based on the seismic profile interpretations with age control from biostratigraphic studies and detrital zircon U-Pb dates of well MZ-1-1 in the western Dongsha-Penghu Uplift of the northern SCS continental margin. The industrial seismic profiles reveal evidence for structural inversion as represented by folds and high-angle reverse faults, formed by reactivation of pre-existing normal faults. The inversion event likely started after the Early Cretaceous, and developed in Late Cretaceous, but ceased before the Cenozoic. The areal extent of the structural inversion was restricted in the western Dongsha-Penghu Uplift and was approximately 100 km in width. Based on the paleogeographic reconstruction of SCS, the structural inversion was likely formed by a collision between the seamount (volcanic islands swarm of the current North Palawan block (mainly the Calamian Islands and the northern SCS continental margin around Late Cretaceous.

Phanerozoic burial, uplift and denudation of the Equatorial Atlantic margin of South America

2017-04-01

We have initiated a study aimed at understanding the history of burial, uplift and denudation of the South American Equatorial Atlantic Margin (SAEAM Uplift) including the Guiana Shield to provide a framework for investigating the hydrocarbon prospectivity of the offshore region. We report first results including observations from fieldwork at the northern and southern flank of the Guiana Shield. The study combines apatite fission-track analysis (AFTA) and vitrinite reflectance data from samples of outcrops and drillcores, sonic velocity data from drill holes and stratigraphic landscape analysis (mapping of peneplains) - all constrained by geological evidence, following the methods of Green et al. (2013). The study will thus combine the thermal history from AFTA data with the denudation history from stratigraphic landscape analysis to provide magnitudes and timing of vertical movements (Japsen et al. 2012, 2016). Along the Atlantic margin of Suriname and French Guiana, tilted and truncated Lower Cretaceous strata rest on Precambrian basement (Sapin et al. 2016). Our AFTA data show that the basement underwent Mesozoic exhumation prior to deposition of the Lower Cretaceous cover. Sub-horizontal peneplains define the landscape of the Guiana Shield at elevations up to 500 m a.s.l. As these sub-horizontal peneplains truncate the tilted, sub-Cretaceous surface along the Atlantic margin, these peneplains were therefore formed and uplifted in post-Cretaceous time. This interpretation is in good agreement with our AFTA data that define Paleogene exhumation along the margin and with the results of Theveniaut and Freyssinet (2002) who used palaeomagnetic data to conclude that bauxitic surfaces across basement at up to 400 m a.s.l. on the Guiana Shield formed during the Palaeogene. Integration of the results from AFTA with stratigraphic landscape analysis (currently in progress) and geological evidence will provide a robust reconstruction of the tectonic development of the

Vietnamese migrants underutilize and are a "hard to reach group" within the existing mental health care system in Germany. We analyzed migration related and clinical data for all first-time Vietnamese migrants seeking psychiatric help, within the first 30 months of a newly established outpatient clinic, offering culture-sensitive psychiatric treatment in native Vietnamese language. Most first time patients were female, first generation Vietnamese migrants with poor German language skills. Only 1 /3 of all patients had a psychiatric history, while this number was higher in patients with schizophrenia. Over time, more first time patients with depression were seeking psychiatric care, accompanied with an increase of non-professional referrals within the Vietnamese communities. This first study on mental health care utilization in Vietnamese migrants in Germany points towards the fact that "migrants" cannot be considered as a homogeneous group. Mental health care utilization must be evaluated for specific migrant groups, and can be initially improved if offered in native language and when it is referred to by members of migrant communities. © Georg Thieme Verlag KG Stuttgart · New York.

Trace element and isotopic compositions of Vietnamese basalts: implications for mantle dynamics in the southeast Asian region

International Nuclear Information System (INIS)

Nguyen, H.; Fower, M.; Nguyen, H.; Nguyen, X.B.; Nguyen, T.Y.

1996-01-01

Cenozoic basalts in Indo-China are part of a regional melting episode along the rifted Eurasian margin. Trace element and isotopic compositions of Vietnamese basalts are used to place constraints on the extent of lithospheric and asthenosphere contributions to the melts and possible mantle dynamic implications. The 87 Sr/ 86 Sr, 207 Pb/ 204 Pb, and 208 Pb/ 204 Pb isotopic ratios of the basalts reflect minimal crustal wall rock reaction, and variable enrichment in EM1 and EM2 of a 208 Pb-rich MORB-like source. Some, but not all, of this variation corresponds to the age of lithospheric sector penetrated. Basalts erupted through a cratonic, central sector (e.g. at Quang Ngai, Pleiku, Song Cau, Kong Plong, and Buon Ma Thuot) and off-cratonic, southwest sector (e.g. Phuoc Long) resemble those of EM2-rich basalts from southern and southeaster China and the South China Sea. Basalts from an off-cratonic, southeast sector (e.g. from Dalat, Xuan Loc, and the offshore Ile des Cendres-Phu Cuy complex) reflect mixing between a low- 206 Pb/ 204 Pb, high- 208 Pb/ 204 Pb, EM1-like component, and resemble basalts from northwest Taiwan, eastern and northeastern China, and parts of the Japan Sea. While EM2 tends to characterise lithospheric sectors, presence of EM1 in off-cratonic rather than cratonic basalts implies an asthenosphere rather than lithospheric source. Pervasive presence of EM1 in southeast Asian and marginal basin asthenosphere corresponds with thermally-anomalous mantle and may involve delaminated cratonic substrate entrained by mobile, extruded asthenosphere.

Mental health and illness in Vietnamese refugees.

Science.gov (United States)

Gold, S J

1992-09-01

Despite their impressive progress in adapting to American life, many Vietnamese still suffer from wartime experiences, culture shock, the loss of loved ones, and economic hardship. Although this trauma creates substantial mental health needs, culture, experience, and the complexity of the American resettlement system often block obtaining assistance. Vietnamese mental health needs are best understood in terms of the family unit, which is extended, collectivistic, and patriarchal. Many refugees suffer from broken family status. They also experience role reversals wherein the increased social and economic power of women and children (versus men and adults) disrupts the traditional family ethos. Finally, cultural conflicts often make communication between practitioners and clients difficult and obscure central issues in mental health treatment. Rather than treating symptoms alone, mental health workers should acknowledge the cultural, familial, and historical context of Vietnamese refugees.

Initiation of extension in South China continental margin during the active-passive margin transition: kinematic and thermochronological constraints

Science.gov (United States)

ZUO, Xuran; CHAN, Lung

2015-04-01

The southern South China Block is characterized by a widespread magmatic belt, prominent NE-striking fault zones and numerous rifted basins filled by Cretaceous-Eocene sediments. The geology denotes a transition from an active to a passive margin, which led to rapid modifications of crustal stress configuration and reactivation of older faults in this area. In this study, we used zircon fission-track dating (ZFT) and numerical modeling to examine the timing and kinematics of the active-passive margin transition. Our ZFT results on granitic plutons in the SW Cathaysia Block show two episodes of exhumation of the granitic plutons. The first episode, occurring during 170 Ma - 120 Ma, affected local parts of the Nanling Range. The second episode, a more regional exhumation event, occurred during 115 Ma - 70 Ma. Numerical geodynamic modeling was conducted to simulate the subduction between the paleo-Pacific plate and the South China Block. The modeling results could explain the observation based on ZFT data that exhumation of the granite-dominant Nanling Range occurred at an earlier time than the gneiss-dominant Yunkai Terrane. In addition to the difference in geology between Yunkai and Nanling, the heating from Jurassic-Early Cretaceous magmatism in the Nanling Range may have softened the upper crust, causing the area to exhume more readily. Numerical modeling results also indicate that (1) high slab dip angle, high geothermal gradient of lithosphere and low convergence velocity favor the subduction process and the reversal of crustal stress state from compression to extension in the upper plate; (2) the late Mesozoic magmatism in South China was probably caused by a slab roll-back; and (3) crustal extension could have occurred prior to the cessation of plate subduction. The inversion of stress regime in the continental crust from compression to crustal extension has shed light on the geological condition producing the red bed basins during Late Cretaceous

Recent US data indicate that women of Vietnamese descent have higher cervical cancer incidence rates than women of any other race/ethnicity, and lower levels of Pap testing than white, black, and Latina women. Our objective was to provide information about Pap testing barriers and facilitators that could be used to develop cervical cancer control intervention programs for Vietnamese American women. We conducted a cross-sectional, community-based survey of Vietnamese immigrants. Our study was conducted in metropolitan Seattle, Washington, DC. A total of 1532 Vietnamese American women participated in the study. Demographic, health care, and knowledge/belief items associated with previous cervical cancer screening participation (ever screened and screened according to interval screening guidelines) were examined. Eighty-one percentage of the respondents had been screened for cervical cancer in the previous three years. Recent Pap testing was strongly associated (p<0.001) with having a regular doctor, having a physical in the last year, previous physician recommendation for testing, and having asked a physician for testing. Women whose regular doctor was a Vietnamese man were no more likely to have received a recent Pap smear than those with no regular doctor. Our findings indicate that cervical cancer screening disparities between Vietnamese and other racial/ethnic groups are decreasing. Efforts to further increase Pap smear receipt in Vietnamese American communities should enable women without a source of health care to find a regular provider. Additionally, intervention programs should improve patient-provider communication by encouraging health care providers (especially male Vietnamese physicians serving women living in ethnic enclaves) to recommend Pap testing, as well as by empowering Vietnamese women to specifically ask their physicians for Pap testing.

Vietnamese women in struggle for national independence.

Science.gov (United States)

1998-01-01

The 30-year struggle for independence in Viet Nam took a huge toll on women, but even in the hardest times, Vietnamese women received support from the world-wide women's movement. As the world prepares to enter the new millennium, it is important to determine what policies can be created to prevent war and guarantee peace. These policies must grow out of international agreement on basic principles such as respect for independence and sovereignty and must not resort to the embargoes and sanctions that have placed a disproportionate burden on women and children. Another challenge of the new millennium is to encourage implementation of national programs, policies, and measures to help women realize their rights while preserving traditional family values. Despite the heightened visibility of the international women's movement, women still suffer from widespread inequalities. In accordance with the goals of the Communist Party of Viet Nam, the 8th Congress of Vietnamese Women in 1997 created a national plan for women that is a blueprint for the women's movement for the years 1997-2000. Among the goals are creating jobs for women, upgrading their standard of living, eliminating hunger, decreasing poverty, and ensuring that women have educational opportunities. Vietnamese women also seek to strengthen their relationship with other women in the international community, and the Vietnamese Women's Union has actively forwarded the objectives of the Federation of International Democratic Women.

Tectono-Magmatic Evolution of the South Atlantic Continental Margins with Respect to Opening of the Ocean

Science.gov (United States)

Melankholina, E. N.; Sushchevskaya, N. M.

2018-03-01

The history of the opening of the South Atlantic in Early Cretaceous time is considered. It is shown that the determining role for continental breakup preparation has been played by tectono-magmatic events within the limits of the distal margins that developed above the plume head. The formation of the Rio Grande Rise-Walvis Ridge volcanic system along the trace of the hot spot is considered. The magmatism in the South Atlantic margins, its sources, and changes in composition during the evolution are described. On the basis of petrogeochemical data, the peculiarities of rocks with a continental signature are shown. Based on Pb-Sr-Nd isotopic studies, it is found that the manifestations of magmatism in the proximal margins had features of enriched components related to the EM I and EM II sources, sometimes with certain participation of the HIMU source. Within the limits of the Walvis Ridge, as magmatism expanded to the newly formed oceanic crust, the participation of depleted asthenospheric mantle became larger in the composition of magmas. The role played by the Tristan plume in magma generation is discussed: it is the most considered as the heat source that determined the melting of the ancient enriched lithosphere. The specifics of the tectono-magmatic evolution of the South Atlantic is pointed out: the origination during spreading of a number of hot spots above the periphery of the African superplume. The diachronous character of the opening of the ocean is considered in the context of northward progradation of the breakup line and its connection with the northern branch of the Atlantic Ocean in the Mid-Cretaceous.

Overall, Vietnamese with its isolating character and rigid word order provides us with unusually direct evidence for an articulated VP structure.

2015-03-01

Vietnamese women are at particular risk of osteoporosis and its complications. This study examined osteoporosis knowledge and awareness among Vietnamese women who have accessed health care. A sample of 217 women, 13 to 76 years of age, who were attending 1 of 2 health care facilities in Da Nang, Vietnam, between November and December 2009 completed a questionnaire assessing their awareness of osteoporosis and measuring their knowledge using a 30-item instrument reflecting 9 knowledge domains (eg, risk factors, diagnosis, prognosis). A majority (81.6%) of the women had heard of osteoporosis. Awareness was associated with education, working in health care, and having a family member with osteoporosis. On average, Vietnamese women answered 49% of the knowledge questions correctly; scores ranged from 0 to 26 questions correct out of 30 (mean = 14.71 ± 5.2, median = 15). Mean knowledge scores were higher among those reporting a family member with osteoporosis, nurses (vs other vocations), and women with a high school education or greater (relative to those who had not completed high school). More than 90% of the women expressed interest in a prevention and treatment program. Vietnamese women may have heard of osteoporosis, yet they would benefit from education targeting prevention and treatment of the disease. © 2011 APJPH.

This article is based on an embedded case study of selected older people's self-help groups in urban South Korea, which aim to assist community-dwelling older adults, particularly poor and marginalized women, to age in their community and remain active and contributing members. The study highlights the importance of the role and capacity of nongovernmental organizations (NGOs) as partner organizations. Implications are important for other aging societies, particularly in Asia, where older women have been often confined by patriarchal oppression.

Perceptions of Vietnamese fathers' acculturation levels, parenting styles, and mental health outcomes in Vietnamese American adolescent immigrants.

Nguyen, Peter V

2008-10-01

Vietnamese adult and adolescent immigrants in the United States acculturate to the Western culture at different rates. MostVietnamese parents tend to use the authoritarian parenting method in which dictatorial approaches are enforced, possibly leading to family conflicts and mental health issues. By means of the Suinn-Lew Asian Self-Identity Acculturation Scale, the Parental Authority Questionnaire, the Rosenberg Self-Esteem Scale, and the Reynolds Adolescent Depression Inventory, this exploratory study surveyed 290Vietnamese American adolescents in a major metropolitan area to examine the relationship between their fathers' acculturation levels and parenting styles and the relationships among parenting styles and self-esteem levels and depression scores of the adolescents. Findings revealed that most of the adolescents perceived that their fathers have not acculturated to the U.S. culture and continue to practice the traditional authoritarian parenting style, regardless of the amount of time spent in the United States. Furthermore, results indicate that adolescents who perceived their fathers as using the authoritarian parenting style reported lower levels of self-esteem and higher depression scores when compared with those who perceived their fathers as using the authoritative parenting style.

Vietnam is frequently thought of as the location of the world's largest dioxin contamination, with over 400 pounds of 2,3,7,8-TCDD from Agent Orange defoliant sprayed from 1962 to 1971. Although this is true, distribution of dioxin from Agent Orange is far from ubiquitous in Vietnam. The north was never sprayed and only certain areas of central and south Vietnam were sprayed. Dioxins have been found in very high levels in human milk and in food in some select areas of Vietnam from the 1970s to the present. Other pesticides including DDT and metabolites, {alpha}, {beta}, and {gamma} HCH, and HCB have also been found in humans and in food. We review dioxin ''hot spots'' studied in the past with current suspect hot spots and also add to the chemicals studied in Vietnamese by measuring polybrominated diphenyl ether (PBDE) flame retardants in nursing Vietnamese women's milk and compare these to levels from other countries.

Full Text Available In this study, the caffeine contents in five certain Vietnamese coffee (Dak Tin, Di Linh, Nam Nguyen, Origin and Vinacafe found in the Vietnamese market were determined using UV/vis spectrophotometry. The quantification of caffeine sample was calculated by standard addition method. Our results showed that the caffeine contents in coffee brewing were influenced by temperature of water used to brew, time of brewing, and independent on the volume of water, respectively. In general, higher concentrations of caffeine were found in all samples prepared at temperature 100°C for 5 minutes. The order of caffeine contents in coffee samples was Dak Tin, Di Linh, Nam Nguyen, Origin and Vinacafe, respectively. This study can contribute to a better knowledge of caffeine contents in Vietnamese coffee of Vietnamese consumers.

From the view point of applying to laboratory exercise of radioactivity measurement by a Liquid Scintillation Counter (LSC), Vietnamese vodkas have specific features as measurement samples, for example, they are colorless, have high ethanol content, and only very few organic materials are included. Investigation was made to make sure that the Vietnamese vodkas are appropriate or not as a measurement sample for the LSC exercise. Direct measurements of 14 C without any chemical pre-treatment were made on both radioactive concentrations and specific activities of three kinds of Vietnamese vodka and also pure ethanol reagent. The LSC measurements reveal that estimated 14 C concentration is proportional to ethanol content in samples and that specific activity of 14 C shows good agreement among the Vietnamese vodkas and pure ethanol, as well as the reference value of 0.25 Bq/g of Carbon. Thus the conclusion is derived that the Vietnamese vodkas can be applied with high accuracy to the LSC exercise as measurement samples. (author)

Rifted continental margins may present a predominantly magmatic continent-ocean transition (COT), or one characterized by large exposures of serpentinized mantle. In this study we use numerical modeling to show the importance of the lower crustal strength in controlling the amount and onset of melting and serpentinization during rifting. We propose that the relative timing between both events controls the nature of the COT. Numerical experiments for half-extension velocities serpentinized mantle underlain by some magmatic products. In contrast, a weak lower crust promotes margins with a gentle crustal tapering, small faults dipping both ocean- and landward and small syn-rift subsidence. Their COT is predominantly magmatic at any ultra-slow extension velocity and perhaps underlain by some serpentinized mantle. These margins can also be either symmetric or asymmetric. Our models predict that magmatic underplating mostly underlies the wide margin at weak asymmetric conjugates, whereas the wide margin is mainly underlain by serpentinized mantle at strong asymmetric margins. Based on this conceptual template, we propose different natures for the COTs in the South Atlantic.

There is a lack of information regarding marine radioactivity in sediments of the Continental Margin of the South Atlantic. "1"3"7Cs and "4"0K radioactivity and sedimentological variables were determined in superficial sediment samples. It was demonstrated that "4"0K is a good indicator for sediment granulometry, whilst "1"3"7Cs presents a good correlation with its chemical composition. Moreover, it was identified through the radiometric data the occurrence of input of allochtonous matter to the Brazilian southernmost compartment from the Rio de La Plata estuary, as previously reported in the literature.

Vietnamese Migrant Workers in Thailand - Implications for Leveraging Migration for Development

Directory of Open Access Journals (Sweden)

2014-05-01

Full Text Available A greater flow of people to and from each of the Mekong countries is catching the attention of the general public and academic researchers. As one of the fastest growing countries in the GMS, Thailand is attracting the majority of migrant workers from its neighbours. At a smaller scale, when compared with those from Lao PDR, Cambodia and Myanmar, Vietnamese workers are also joining this increasing trend in immigration to Thailand. By analyzing information from secondary data sources, this research paper attempts to provide further insights into the social and economic impacts generated by the Vietnamese migrant workers in Thailand both at home and the host country. The study discovers that moving to Thailand for work has eased the pressures of rural unemployment and underemployment that have plagued Vietnam recently. Meanwhile, Vietnamese workers are helping soothe the stress caused by the increasing demand for unskilled and low skilled labourers in Thailand. The study further learns that the long-established community of Vietnamese migrants in Thailand is encouraging the increasing movement of Vietnamese workers to Thailand. The study findings suggest meaningful implications for future policies in leveraging labour migration for development.

Wobbe, Florian; Lindeque, Ansa; Gohl, Karsten

2014-12-01

Paleotopographic models of the West Antarctic margin, which are essential for robust simulations of paleoclimate scenarios, lack information on sediment thickness and geodynamic conditions, resulting in large uncertainties. A new total sediment thickness grid spanning the Ross Sea-Amundsen Sea-Bellingshausen Sea basins is presented and is based on all the available seismic reflection, borehole, and gravity modeling data offshore West Antarctica. This grid was combined with NGDC's global 5 arc minute grid of ocean sediment thickness (Whittaker et al., 2013) and extends the NGDC grid further to the south. Sediment thickness along the West Antarctic margin tends to be 3-4 km larger than previously assumed. The sediment volume in the Bellingshausen, Amundsen, and Ross Sea basins amounts to 3.61, 3.58, and 2.78 million km3, respectively. The residual basement topography of the South Pacific has been revised and the new data show an asymmetric trend over the Pacific-Antarctic Ridge. Values are anomalously high south of the spreading ridge and in the Ross Sea area, where the topography seems to be affected by persistent mantle processes. In contrast, the basement topography offshore Marie Byrd Land cannot be attributed to dynamic topography, but rather to crustal thickening due to intraplate volcanism. Present-day dynamic topography models disagree with the presented revised basement topography of the South Pacific, rendering paleotopographic reconstructions with such a limited dataset still fairly uncertain.

This study explored Arabic, Chinese, South Asian, and Vietnamese immigrant women's experiences with a peer health educator program, a public health program that facilitated access to breast health information and mammography screening. Framed within critical social theory, this participatory action research project took place from July 2009 to January 2011. Ten focus groups and 14 individual interviews were conducted with 82 immigrant women 40 years of age and older. Qualitative methods were utilized. Thematic content analysis derived from grounded theory and other qualitative literature was employed to analyze data. Four dominant themes emerged: Breast Cancer Prevention focused on learning within the program, Social Support provided by the peer health educator and other women, Screening Services Access for Women centered on service provision, and Program Enhancements related to specific modifications required to meet the needs of immigrant women accessing the program. The findings provide insights into strategies used to promote breast health, mammography screening, and the improvement of public health programming. Perceived barriers that continue to persist are structural barriers, such as the provision of information on breast cancer and screening by family physicians. A future goal is to improve collaborations between public health and primary care to minimize this barrier.

Giang Huynh

2014-12-01

Full Text Available This study examines Vietnamese female consumers’ attitudes towards counterfeit branded products; by investigating the influence of brand image, product involvement and price advantage towards decision-making processes associated with purchasing and ownership. An inductive anti-positivist approach was adopted, employing qualitative methods; drawing from in-depth interviews distilled and synthesized using Word Cloud software, as Geographic Information System (GIS based Spatial Analyses. Findings suggest that Price Advantage plays a determining and predominant role in encouraging consumers’ purchase intention of a counterfeit product. In addition, Brand Image has positive effect on the purchase intention as well; while product involvement plays no significant role in the process. Further observations point to there being paucity of literature that focuses on Vietnamese and ASEAN markets. With this is mind, a new conceptual framework was developed to reflect the nuances of the Vietnamese consumer experience; which it is suggested will be of value to scholars, practitioners and further studies.

Full Text Available Introduction: In January 2011, Sydney South West Public Health Unit was notified of a large number of people presenting with gastroenteritis over two days at a local hospital emergency department (ED.Methods: Case-finding was conducted through hospital EDs and general practitioners, which resulted in the notification of 154 possible cases, from which 83 outbreak cases were identified. Fifty-eight cases were interviewed about demographics, symptom profile and food histories. Stool samples were collected and submitted for analysis. An inspection was conducted at a Vietnamese bakery and food samples were collected and submitted for analysis. Further case ascertainment occurred to ensure control measures were successful.Results: Of the 58 interviewed cases, the symptom profile included diarrhoea (100%, fever (79.3% and vomiting (89.7%. Salmonella Typhimurium multiple-locus-variable number tandem repeats analysis (MLVA type 3-10-8-9-523 was identified in 95.9% (47/49 of stool samples. Cases reported consuming chicken, pork or salad rolls from a single Vietnamese bakery. Environmental swabs detected widespread contamination with Salmonella at the premises.Discussion: This was a large point-source outbreak associated with the consumption of Vietnamese-style pork, chicken and salad rolls. These foods have been responsible for significant outbreaks in the past. The typical ingredients of raw egg butter or mayonnaise and pate are often implicated, as are the food-handling practices in food outlets. This indicates the need for education in better food-handling practices, including the benefits of using safer products. Ongoing surveillance will monitor the success of new food regulations introduced in New South Wales during 2011 for improving food-handling practices and reducing foodborne illness.

Hepatitis B is a significant public health challenge within some subpopulations in Australia, including Chinese and Vietnamese migrants. There has been limited research on hepatitis B knowledge and actions in these communities. The authors conducted a self-administered survey among 442 Chinese and 433 Vietnamese in Brisbane. Generally, the knowledge is best described as "moderate." One in 2 could not identify the sexual transmission risk and less than one third knew that sharing foods or drinks did not spread the disease. The majority of Vietnamese (80%) and 60% of Chinese respondents indicated prior testing. Vaccination was reported in 60% of the Vietnamese and in 52% of the Chinese. Knowledge was better among Chinese people who had been tested and vaccinated compared with those who were nontested and nonvaccinated. Only 3.5% of the Chinese, but 11.6% of the Vietnamese, indicated having a positive test result hepatitis B virus. This study helps identify strategies for programs targeting both communities and practitioners.

Compressed air systems in a Vietnamese footwear manufacturing enterprise consume about 10% of enterprise's total electric power supply. Energy efficiency of these air compressor systems, either equipped with new and efficient compressors or old and inefficient ones, can only reach between 5% and 10%. In other words, regardless whatever air compressors were installed, energy loss from the compressor systems was over 80%. This study discovered that energy loss was due to non-optimized operations of the air compressor systems and air leakages. The objectives of the paper are to uncover energy saving potential in Vietnamese air compressor systems, demonstrate methodologies used in the auditing and assessment, share auditing and assessment results, and serve a guide on how to analyze energy efficiency in a compressed air system. This paper concludes that energy efficiency investment in air compressor systems in the Vietnamese enterprise could be extremely cost-effective. If the enterprise invests USD 84,000 in the air compressors to improve efficiency performance, the investment capital will be recovered in about six months. The net present value of the investment will be about USD 864,000 at a discount rate of 12%. (author)

Nasalance is used to evaluate the velopharyngeal incompetence in clinical diagnoses using a nasometer. The aim of this study is to find the nasalance differences between Vietnamese cleft palate children and Korean cleft palate children by measuring the nasalance of five oral vowels. Ten Vietnamese cleft palate children after surgery, three Vietnamese children for the control group, and ten Korean cleft palate children after surgery with the same age participated in this experimentation. Instead of Korean control, the standard value of Korean version of the simplified nasometric assessment procedures (kSNAP) was used. The results are as follows: (1) the highest nasalance score among the Vietnamese normal vowels is the low vowel /a/; however, that of Korean normal vowels is the high vowel /i/. (2) The average nasalance score of Korean cleft palate vowels is 18% higher than that of Vietnamese cleft palate vowels. There was a nasalance score of over 45% among the vowels /e/ and /i/ in Vietnamese cleft palate patients and /i/, /o/, and /u/ in Korean cleft palate patients. These different nasalance scores of the same vowels seem to cause an ethnic difference between Vietnamese and Korean cleft palate children.

Mental-illness-related (MIR) stigma is recognized as a major barrier to health care. Yet very little is known about mental illness and stigma among Vietnamese populations, or how emigration and acculturation processes might affect traditional views. Focus group discussions were conducted with Vietnamese Americans in New Orleans (Louisiana) and Vietnamese nationals in Bui Chu (Vietnam), who shared historical and cultural backgrounds, in 2010 to assess differences in their perceptions of mental illness and stigma. Results show several significant differences in mental illness perceptions between Vietnamese Americans and Vietnamese nationals, while MIR stigma seemed prevalent and understanding of mental illness was low among both groups.

2015-04-01

The Mesozoïc Egyptian margin is the south margin of a remnant of the Neo-Tethys Ocean, at the African northern plate boundary. East Mediterranean basin developed during the late Triassic-Early Jurassic rifting with a NW-SE opening direction (Frizon de Lamotte et al., 2011). During Mesozoïc, Egypt margin was a transform margin with a NW-SE orientation of transform faults. In the Eastern Mediterranean basin, Mesozoïc margins are characterized by mixed carbonate-siliciclastics platforms where subsidence and eustacy are the main parameters controlling the facies distribution and geometries of the platform-to-basin transition. Geometries and facies on the platform-slope-basin system, today well constrained on the Levant area, where still poorly known on the Egyptian margin. Geometries and stratigraphic architecture of the Egyptian margin are revealed, thanks to a regional seismic and well data-base provided by an industrial-academic group (GRI, Total). The objective is to understand the sismostratigraphic architecture of the platform-slope-basin system in a key area from Western Desert to Nile delta and Levant margin. Mapping of the top Jurassic and top Cretaceous show seismic geomorphology of the margin, with the cartography of the hinge line from Western Desert to Sinaï. During the Jurassic, carbonate platform show a prograding profile and a distally thickening of the external platform, non-abrupt slope profiles, and palaeovalleys incisions. Since the Cretaceous, the aggrading and retrograding mixed carbonate-siliciclastic platform show an alternation of steep NW-SE oblique segments and distally steepened segments. These structures of the platform edge are strongly controlled by the inherited tethyan transform directions. Along the hinge line, embayments are interpreted as megaslides. The basin infilling is characterised by an alternation of chaotic seismic facies and high amplitude reflectors onlaping the paleoslopes. MTC deposits can mobilize thick sedimentary

Full Text Available This paper is a case study to a Vietnamese English learner. The main objective of the study was to describe how the English of a Vietnamese student developed. Interviews were conducted in order to collect the data. The interviews were tape recorded. The recorded data provided information about the learner’s background. Additionally the data served as a sample of the learner’s spoken English. The analysis of the sample revealed that the learner made several grammatical, syntactical, and phonological errors. With a contrastive analysis theory it could be concluded that one of the factors that might have triggered the errors were the difference between English and Vietnamese language. From a personality point of view, the subject of the study showed several positive personalities that supported the development of his English as a second language.

Late Paleozoic SEDEX deposits in South China formed in a carbonate platform at the northern margin of Gondwana

Science.gov (United States)

Qiu, Wenhong Johnson; Zhou, Mei-Fu; Liu, Zerui Ray

2018-05-01

SEDEX sulfide deposits hosted in black shale and carbonate are common in the South China Block. The Dajiangping pyrite deposit is the largest of these deposits and is made up of stratiform orebodies hosted in black shales. Sandstone interlayered with stratiform orebodies contains detrital zircon grains with the youngest ages of 429 Ma. Pyrite from the orebodies has a Re-Os isochron age of 389 ± 62 Ma, indicative of formation of the hosting strata and syngenetic pyrite ores in the mid-late Devonian. The hosting strata is a transgression sequence in a passive margin and composed of carbonaceous limestone in the lower part and black shales in the upper part. The ore-hosting black shales have high TOC (total organic carbon), Mo, As, Pb, Zn and Cd, indicating an anoxic-euxinic deep basin origin. The high redox proxies, V/(V + Ni) > 0.6 and V/Cr > 1, and the positive correlations of TOC with Mo and V in black shales are also consistent with an anoxic depositional environment. The Dajiangping deposit is located close to the NE-trending Wuchuan-Sihui fault, which was active during the Devonian. The mid-late Devonian mineralization age and the anoxic-euxinic deep basinal condition of this deposit thus imply that the formation of this deposit was causally linked to hydrothermal fluid exhalation in an anoxic fault-bounded basin that developed in a carbonate platform of the South China Block. The regional distribution of many Devonian, stratiform, carbonaceous sediment-hosted sulfide deposits along the NE-trending fault-bounded basins in South China, similar to the Dajiangping deposit, indicates that these deposits formed at a basin developed in the passive margin setting of the South China Block during the Devonian. This environment was caused by the break-up and northward migration of the South China Block from Gandwana.

The incidence of early-onset (under 50 years of age) colorectal cancer (CRC) in the Vietnamese has been reported to be quite higher than that in the Japanese. To clarify the differences in genetic alterations between Vietnamese and Japanese CRCs, we investigated mutations in K-ras and mitochondrial DNA (mtDNA) and high-frequency microsatellite instability (MSI-H) in the CRCs of Vietnamese and Japanese patients. We enrolled 60 Vietnamese and 233 Japanese patients with invasive CRCs. DNA was extracted from formalin-fixed, paraffin-embedded tissue sections. K-ras mutations were examined with PCR-single-strand conformation polymorphism analysis. mtDNA mutations and MSI-H were examined with microsatellite analysis using D310 and BAT-26, respectively. K-ras mutations were examined in 60 Vietnamese and 45 Japanese CRCs. The frequency of the mutations in the Vietnamese CRCs was significantly higher than that in the Japanese CRCs (8 of 24 [33%] vs 5 of 45 [11%], p =0.048). MSI-H was examined in 60 Vietnamese and 130 Japanese CRCs. The frequency of MSI-H in the Vietnamese CRCs was also significantly higher than that in the Japanese CRCs (6 of 27 [22%] vs 10 of 130 [8%], p =0.030). mtDNA mutations were examined in 60 Vietnamese and 138 Japanese CRCs. The frequency of mtDNA mutations in the Vietnamese CRCs was significantly higher than that in the Japanese CRCs (19 of 44 [43%] vs 11 of 133 [9%], p Vietnamese and Japanese patients. These results indicate that the developmental pathways of CRCs in the Vietnamese may differ from those of CRCs in the Japanese.

After adjusting for confounding variables, age and higher education were positively associated with higher pretest scores and having a physician who spoke English or Vietnamese was negatively associated with higher pretest scores. Additionally, after adjusting for confounding variables, household income, education, and having an HCV-infected family member significantly increased knowledge scores. Conclusions Promotion and development of HCV educational programs can increase HCV knowledge among race and ethnic groups, such as Vietnamese Americans. Giving timely information to at-risk groups provides the opportunity to correct misconceptions, decrease HCV risk behaviors, and encourage testing that might improve timely HCV diagnosis and treatment.

Full Text Available Stigma regarding viral hepatitis and liver disease has psychological and social consequences including causing negative self-image, disrupting relationships, and providing a barrier to prevention, testing, and treatment. The aim of this study was to characterize and compare HBV knowledge and stigma in Vietnamese in Ho Chi Minh City and Chicago and to begin to evaluate the cultural context of HBV stigma. Methods. A written survey including knowledge questions and a validated HBV stigma questionnaire was distributed to Vietnamese in Ho Chi Minh City and Chicago. 842 surveys from Ho Chi Minh City and 170 from Chicago were analyzed. Results. Vietnamese living in Chicago had better understanding of HBV transmission and that HBV can cause chronic infection and liver cancer. Vietnamese in Chicago had higher stigma scores on a broad range of items including guilt and shame about HBV and were more likely to feel that persons with HBV can bring harm to others and should be isolated. Conclusions. Vietnamese in Ho Chi Minh City and Chicago have knowledge deficits about HBV, particularly regarding modes of transmission. Persons in Ho Chi Minh City expressed lower levels of HBV stigma than Vietnamese living in Chicago, likely reflecting changing cultural attitudes in Vietnam. Culturally appropriate educational initiatives are needed to address the problem of HBV stigma.

The post-partum period is a stressful time of change, particularly for immigrant women, but, to the best of the present authors' knowledge, the subject has not been explored. This study aimed to examine immigrant women's post-partum stress, depression, and levels of social support, and to determine the predictors of post-partum stress for Vietnamese immigrant women in Taiwan. A cross-sectional design was used. In this descriptive survey, 208 Vietnamese immigrant women were telephone interviewed by a trained Vietnamese research assistant during one of their 6 weeks post-partum. Data were collected through telephone interviews using three questionnaires, including the Hung Postpartum Stress Scale, Beck Depression Inventory, and Social Support Scale. The result shows that Vietnamese women had low level post-partum stress scores. Participants' family support rated higher than friend support. The incidence of depression was 0.5%. Social support, number of post-partum days, and family income were found to be predictors for post-partum stress, accounting for 26.6% of the variance. The Vietnamese immigrant women experienced significant stress regarding their maternal roles and received most of their support from their families rather than from friends. Nurses caring for this cohort should therefore consider these factors in order to help them cope with their post-partum stress. Healthcare providers should offer available resources to these immigrant women and their spouses during this critical period in their lives. For instance, antenatal education classes could be provided to help immigrant women manage and overcome post-partum issues. © 2015 Japan Academy of Nursing Science.

To investigate the optic disc parameters by optical coherence tomography (OCT) in Vietnamese with various types of glaucoma. Medical charts of Vietnamese and White patients within a single practice were reviewed. Disc and rim areas by OCT were compared among nonglaucoma controls, different types of glaucoma, and glaucoma suspect. The association of these parameters with demographic and ocular features was evaluated. Data from 1416 Vietnamese and 57 White patients were included. A larger mean disc area was observed in eyes with primary angle-closure glaucoma than in eyes with primary angle-closure and primary angle-closure suspect (both PVietnamese patients with glaucoma and glaucoma suspicion had larger discs than diagnosis-matched Whites (P=0.043 and 0.021, respectively). Vietnamese patients with glaucoma seem to have larger optic discs than White patients. Central corneal thickness had no association with disc area in this study population.

The continental margin of the northern South China Sea (SCS) had experienced continuous evolution from an active continental margin in the late Mesozoic to a passive continental margin in the Cenozoic. The 1200km-long Littoral Faults Zone (LFZ) off the mainland South China was suggested to represent one of the sub-plate boundaries and play a key role during the evolution. Besides, four devastating earthquakes with magnitude over 7 and another 11 destructive events with M>6 were documented to have occurred along the LFZ. However, its approximity to the shoreline, the shallow water depth, and the heavy fishing activities make it hard to conduct a marine seismic investigation. As a result, understandings about the LFZ before 2000 were relatively poor and mostly descriptive. After two experiments of joint onshore-offshore wide-angle seismic surveys in the 1st decade of this century, several cruses aiming to unveil the deep structure of the LFZ were performed in the past few years, with five joint onshore-offshore wide-angle seismic survey profiles completed. Each of these profiles is perpendicular to the shoreline, with four to five seismometers of campaign mode deployed on the landside and over ten Ocean Bottom Seismometers (OBSs) spacing at 20km deployed on the seaside. Meanwhile, multi-channel seismic (MCS) data along these profiles were obtained simultaneously. Based on these data, velocity models from both forward modeling and inversion were obtained. According to these models, the LFZ was imaged to be a low-velocity fractured zone dipping to the SSE-SE at a high-angle and cutting through the thinned continental crust at some locations. Width of the fractured zone varies from 6km to more than 10km from site to site. With these results, it is suggested that the LFZ accommodates the stresses from both the east side, where the Eurasia/Philippine Sea plate converging and mountain building is ongoing, and the west side, where a strike-slip between the Indochina

The Vietnamese Power system is expected to expand considerably in upcoming decades. Power capacities installed are projected to grow from 39 GW in 2015 to 129.5 GW by 2030. Installed wind power capacities are expected to grow to 6 GW (0.8 GW 2015) and solar power capacities to 12 GW (0.85 GW 2015). This goes hand in hand with an increase of the renewable penetration in the power mix from 1.3% from wind and photovoltaics (PV) in 2015 to 5.4% by 2030. The overall potential for wind power in Vietnam is estimated to be around 24 GW. Moreover, the up-scaling of renewable energy sources was formulated as one of the priorized targets of the Vietnamese government in the National Power Development Plan VII. In this work, we investigate the transition of the Vietnamese power system towards high shares of renewables. For this purpose, we jointly optimise the expansion of renewable generation facilities for wind and PV, and the transmission grid within renewable build-up pathways until 2030 and beyond. To simulate the Vietnamese power system and its generation from renewable sources, we use highly spatially and temporally resolved historical weather and load data and the open source modelling toolbox Python for Power System Analysis (PyPSA). We show that the highest potential of renewable generation for wind and PV is observed in southern Vietnam and discuss the resulting need for transmission grid extensions in dependency of the optimal pathway. Furthermore, we show that the smoothing effect of wind power has several considerable beneficial effects and that the Vietnamese hydro power potential can be efficiently used to provide balancing opportunities. This work is part of the R&D Project "Analysis of the Large Scale Integration of Renewable Power into the Future Vietnamese Power System" (GIZ, 2016-2018).

Vietnam is one of the most important countries for pig domestication, and a total of 26 local breeds have been reported. In the present study, genetic relationships among the various pig breeds were investigated using 90 samples collected from local pigs (15 breeds) in 15 distantly separated, distinct areas of the country and six samples from Landrace pigs in Hanoi as an out-group of a common Western breed. All samples were genotyped using the Illumina Porcine SNP60 v2 Genotyping BeadChip. We used 15 160-15 217 SNPs that showed a high degree of polymorphism in the Vietnamese breeds for identifying genetic relationships among the Vietnamese breeds. Principal components analysis showed that most pigs indigenous to Vietnam formed clusters correlated with their original geographic locations. Some Vietnamese breeds formed a cluster that was genetically related to the Western breed Landrace, suggesting the possibility of crossbreeding. These findings will be useful for the conservation and management of Vietnamese local pig breeds. © 2018 Stichting International Foundation for Animal Genetics.

Purpose: Infrequent use of the Western health care by the Vietnamese may be explained by deeply-rooted traditional oral health beliefs and practices unique to the Asian culture. This study investigated Vietnamese oral health beliefs and practices and their relationship to the utilization of Western preventive oral health care services among Vietnamese-Americans. Methods: An exploratory, cross-sectional survey design with a convenience sample of 140 par-ticipants (n = 140) was used for this study. Participants were recruited on site of a Vietnamese-owned business, with questionnaires consisting of 28 questions that were distributed in hard copy by the principal investigator (PI) on multiple occasions and at various times of the day. Results: Spearman Rank Correlations tests showed participants who agreed with the statement, "Regular dental visits will help prevent dental problems," were more likely to utilize medical health services (pissues. No statistical significance was found between age, gender, pri-mary language, years spent in the United States, education level, religion and the Vietnamese survey participants' individual oral beliefs and practices. Conclusion: The results suggest that Vietnamese Americans holding the belief that dental visits help prevent oral health problems, were more likely to utilize Western health care services. The study also supports existing literature that Vietnamese oral health beliefs and practices impact the use of Western health care services.

The prevalence rate and disease manifestations of systemic lupus erythematosus (SLE) have been noted to vary among different ethnic groups. There has been no description in the English literature of SLE in the Vietnamese population. This is the first report, which details the clinical and laboratory features as well as an estimation of the prevalence of SLE in patients with a Vietnamese ancestry living in the United States. We performed a retrospective chart review of clinical and laboratory features of patients of Vietnamese descent with SLE. The case finding was performed by a review of the rheumatology clinic records at two large teaching hospitals in Santa Clara County searching for patients with SLE with a Vietnamese surname. In addition, we recruited patients by contacting all of the rheumatologists practicing in the county. Twenty-three patients of Vietnamese descent were identified with SLE in Santa Clara County. The estimated prevalence of SLE in the patients of Vietnamese descent was 42 cases per 100 000 persons. Eighty-seven per cent of the cases were born in Vietnam. The clinical and laboratory features of SLE were similar to prior published reviews except for a relatively high prevalence of anti-RNP antibody (54%). The patients with anti-RNP antibody exhibited features of overlap syndrome. There was a high rate of exposure to tuberculosis (TB). Fifty-eight per cent of patients had a positive purified protein derivative (PPD) skin test and 27% of patients had a history of clinical TB. Forty-four per cent of patients had evidence of hepatitis B exposure. The prevalence of SLE in the Vietnamese population in Santa Clara County is similar to that of other Asian populations. There was a relatively high prevalence of anti-RNP antibody in our patient group which was associated with overlap features. As expected in an immigrant population from Southeast Asia, there was a high rate of prior exposure to tuberculosis and hepatitis B. Clinicians should diligently

A Character Level Based and Word Level Based Approach for Chinese-Vietnamese Machine Translation

Full Text Available Chinese and Vietnamese have the same isolated language; that is, the words are not delimited by spaces. In machine translation, word segmentation is often done first when translating from Chinese or Vietnamese into different languages (typically English and vice versa. However, it is a matter for consideration that words may or may not be segmented when translating between two languages in which spaces are not used between words, such as Chinese and Vietnamese. Since Chinese-Vietnamese is a low-resource language pair, the sparse data problem is evident in the translation system of this language pair. Therefore, while translating, whether it should be segmented or not becomes more important. In this paper, we propose a new method for translating Chinese to Vietnamese based on a combination of the advantages of character level and word level translation. In addition, a hybrid approach that combines statistics and rules is used to translate on the word level. And at the character level, a statistical translation is used. The experimental results showed that our method improved the performance of machine translation over that of character or word level translation.

Full Text Available This article approaches domestic tourism in Vietnam from a native Asian perspective aiming to examine Vietnamese domestic travel motivations. This quantitative study is based on a self-administered questionnaire to survey 230 Vietnamese domestic travellers. Results highlight the significant roles of the employer sponsoring the trip, family, travel promotion, and favourable weather in determining travel, in addition to their motivations to seek time for leisure and recreation. Moreover, the study detected a perception gap between the tourist’s demand and the travel agent’s supply. The behaviour of Vietnamese domestic travellers reflects the characteristics of a transition economy and reveals certain aspects which are also peculiar to other Asian countries. --- Die hier präsentierte quantitative Studie untersucht Reisemotive vietnamesischer InlandstouristInnen mittels eines an 230 ProbandInnen gerichteten Fragebogens. Die Ergebnisse heben neben dem Motiv der Freizeitgestaltung und Erholung die signifikante Rolle der Reisefinanzierung durch Arbeit- geberInnen, der Familie, der Tourismuswerbung sowie der Wetterbedingungen für die Reiseentscheidung hervor. Außerdem ergab die Studie, dass sich die touristischen Motivationen vom Angebot der Reiseagenturen unterscheiden. Die Autorinnen argumentieren, dass das Urlaubsverhalten vietnamesischer InlandstouristInnen Charakteristika eines im wirtschaftlichen Umbruch befindenden Landes widerspiegelt sowie Aspekte aufzeigt, die auch in anderen asiatischen Ländern eine wichtige Rolle spielen.

Mitochondrial DNA (mtDNA) has been proposed to be involved in carcinogenesis and aging. The mtDNA 4977 bp deletion is one of the most frequently observed mtDNA mutations in human tissues and may play a role in colorectal cancer (CRC). In the present study, we aimed to evaluate the frequency of mtDNA 4977 bp deletion in CRC tissues and its association with clinical factors. We determined the presence of the 4977 bp common deletion in cancer and normal paired tissue samples from 105 Swedish and 88 Vietnamese patients with CRC using polymerase chain reaction (PCR) assays. The mtDNA 4977 bp deletion was shown to be significantly more frequent in normal tissues in comparison with paired cancer tissues in both Swedish and Vietnamese patients. The 4977 bp common deletion was significantly more frequent in cancer tissues of the Vietnamese patients compared to the Swedish patients, and in Vietnamese cancer tissues, the 4977 bp deletion was significantly over represented in those with localized disease compared to those with disseminated disease. Moreover, we detected nine novel mtDNA deletions and found a significantly higher rate of these in CRC tissues in Swedish in comparison to Vietnamese patients. The mtDNA 4977 bp deletion seems to have an impact on the clinical outcome of CRC in Vietnamese patients, that the Swedish patients accumulate more of the detected novel deletions in CRC tissue compared to Vietnamese patients probably indicates divergent mechanisms in colorectal carcinogenesis.

Research has demonstrated that exposure to life stressors can influence health through a number of pathways. However, knowledge about the patterns of life stressors and their contributions to health in different populations is limited. Vietnamese older women have attracted little research to date in this area. This cross-sectional study used an interview-administered-questionnaire to collect data from 440 Vietnamese older women. Descriptive analysis was used to describe life stressors among Vietnamese older women. Binary analysis and Structural Equation Modelling statistical analysis were used to examine the influences of life stressors on modifiable lifestyle factors, depressive symptoms, physical and mental health among Vietnamese older women. Vietnamese older women in this study commonly reported the experience of losing a close person, including a baby/child, serious health or money problems, violence and disaster. Among the study participants, (1) exposure to more life stressors increased their depressive symptoms, and decreased their physical and mental health; (2) exposure to more life stressors also increased their physical health by increasing their physical activity levels. Life stressors influenced health among Vietnamese older women through different pathways. Interventions to manage stress and depressive symptoms are required for Vietnamese older women in the future.

2012-05-01

Alagille syndrome (ALGS, OMIM #118450) is an autosomal dominant disorder that affects multiple organ systems including the liver, heart, eyes, vertebrae, and face. ALGS is caused by mutations in one of two genes in the Notch Signaling Pathway, Jagged1 (JAG1) or NOTCH2. In this study, analysis of 21 Vietnamese ALGS individuals led to the identification of 19 different mutations (18 JAG1 and 1 NOTCH2), 17 of which are novel, including the third reported NOTCH2 mutation in Alagille Syndrome. The spectrum of JAG1 mutations in the Vietnamese patients is similar to that previously reported, including nine frameshift, three missense, two splice site, one nonsense, two whole gene, and one partial gene deletion. The missense mutations are all likely to be disease causing, as two are loss of cysteines (C22R and C78G) and the third creates a cryptic splice site in exon 9 (G386R). No correlation between genotype and phenotype was observed. Assessment of clinical phenotype revealed that skeletal manifestations occur with a higher frequency than in previously reported Alagille cohorts. Facial features were difficult to assess and a Vietnamese pediatric gastroenterologist was only able to identify the facial phenotype in 61% of the cohort. To assess the agreement among North American dysmorphologists at detecting the presence of ALGS facial features in the Vietnamese patients, 37 clinical dysmorphologists evaluated a photographic panel of 20 Vietnamese children with and without ALGS. The dysmorphologists were unable to identify the individuals with ALGS in the majority of cases, suggesting that evaluation of facial features should not be used in the diagnosis of ALGS in this population. This is the first report of mutations and phenotypic spectrum of ALGS in a Vietnamese population. Copyright © 2012 Wiley Periodicals, Inc.

RUSSIAN-VIETNAMESE MILITARY-TECHNICAL COOPERATION: CHALLENGES AND OPPORTUNITIES FOR RUSSIA

Н В Федоров

2017-12-01

Full Text Available Vietnam plays important role in Russian policy in the Asia-Pacific region. Military-technical cooperation holds special position in Russian-Vietnamese relations. The aim of the article is the detection of the special features of military-technical cooperation between Russia and Vietnam, and also challenges and opportunities it provides for Russian policy. After the collapse of the USSR defense interaction between Russia and Vietnam was determined by commercial foundations. Vietnam needed new Russian weapons to protect its interests, first of all, in the South China Sea. For Moscow military-technical cooperation with Vietnam got economic significance. But later there was a rise of political dimension of cooperation in this sphere, influenced by some external factors. The period of the 2000-2010s was marked by growth of arms sales from Russia to Vietnam. It was mostly caused by the escalation of the South China Sea conflict, for which US-Chinese contradictions began to play an increasing role. Military-technical coopera-tion with Vietnam influenced some aspects of policy of Russia in the region. There was an increase of indi-rect involvement of Russia into the South China Sea conflict. Russian arms sales for Vietnam became one of problems in Russian-Chinese relations. But Russia and China could cope with these disputes, partly because of enlargement of their interaction in international relations, including the demonstration of similar position for some aspects of the South China Sea conflict. In the framework of development of defense cooperation with Vietnam, Russia could get special conditions of access to facilities of Cam Ranh Bay that strengthened its strategic positions in the region. Russian cooperation with Hanoi in military-technical field and general reinforcement of Russian positions in Vietnam might be also a reason for contradictions with the US.

2011-12-01

The effects of acculturation, body perception, and health behaviors on weight status among Vietnamese American students in Houston, Texas were examined for our research. A survey was mailed to 600 randomly selected Vietnamese American students at one university, and 261 complete surveys (response rate, 43.5%) were used for final analyses. Respondents were classified as overweight or normal weight based on the World Health Organization recommended overweight cutoff for Asians (BMI of 23 kg/m(2)). About 32% of respondents were overweight. Men, undergraduate students, and those with an acceptable body perception were more likely to be overweight. Nativity and its interaction with length of US residence were significant predictors of weight status after controlling for other variables. Foreign-born respondents were less likely to be overweight than US-born respondents, but the risk of being overweight with increasing years of US residence was much greater for the foreign-born than for the US-born. The results suggest the need for culturally tailored overweight and obesity prevention programs for Vietnamese Americans.

Innovation is considered as a core element of sustainable competitive advantage in the rapidly changing environment.

Mavundla, Thandisizwe R; Netswera, Fulufhelo G; Toth, Ferenc; Bottoman, Brian; Tenge, Stembele

2010-07-01

Male circumcision is practiced in South Africa among the Xhosa people as a rite of passage from boyhood to manhood. The manhood status achieved after the ritual accords men power and authority in the community over women and uncircumcised men. Therefore, uninitiated men experience great pressures to get circumcised. We describe the experience of newly initiated Xhosa men in East London, South Africa. Interpretive phenomenology was used as the inquiry of choice. Data were collected through focus group discussions in which 14 men participated. The theme of marginalization of uninitiated Xhosa males emerged with two categories: (a) rejection, and (b) lack of respect. The participants revealed that uninitiated men are rejected by the community, their own families, friends, and women. We frame the discussion around the concept of stigma. Acknowledging that uninitiated males are stigmatized can help mitigate stigma, and in turn, the incidence of medical complications from botched circumcisions.

The role of acculturation and collectivism in cancer screening for Vietnamese American women.

Science.gov (United States)

Nguyen, Anh B; Clark, Trenette T

2014-01-01

The aim of this study was to examine the influence of demographic variables and the interplay between collectivism and acculturation on breast and cervical cancer screening outcomes among Vietnamese American women. Convenience sampling was used to recruit 111 Vietnamese women from the Richmond, VA, metropolitan area, who participated in a larger cancer screening intervention. All participants completed measures on demographic variables, collectivism, acculturation, and cancer-screening-related variables (i.e., attitudes, self-efficacy, and screening behavior). Findings indicated that collectivism predicted both positive attitudes and higher levels of self-efficacy with regard to breast and cervical cancer screening. Collectivism also moderated the relationship between acculturation and attitudes toward breast cancer screening such that for women with low levels of collectivistic orientation, increasing acculturation predicted less positive attitudes towards breast cancer screening. This relationship was not found for women with high levels of collectivistic orientation. The current findings highlight the important roles that sociodemographic and cultural variables play in affecting health attitudes, self-efficacy, and behavior among Vietnamese women. The findings potentially inform screening programs that rely on culturally relevant values in helping increase Vietnamese women's motivation to screen.

To explore the oral health perceptions and practices of Vietnamese adolescents 13 to 17 years old in San Jose, Calif. A purposeful sample of 10 Vietnamese parents with adolescent children were recruited at a Temple in San Jose, Calif. After gaining parental consent and adolescent assent, Vietnamese adolescents participated in an audio-taped, 20 to 30 minute, individual, semi-structured interview in English to explore their perceptions about oral health. Interview data were transcribed verbatim. All statements related to each question were identified, and similar statements were grouped into categories. Ten adolescents participated in the study. All reported tooth appearance as the most important reason for oral care, and that oral health, diet and general health were related. All were concerned about dental pain. Of the respondents, 9 believed that having good teeth would give them more confidence, and help them find jobs and romantic partners, while 2 did not follow recommended oral hygiene routines or recognize early signs of disease. Seven participants favored U.S. dentists over Vietnamese dentists. Frequently reported barriers to seeking dental care were fear of dental treatment (n=7) and inability to pay for dental care (n=6). When educating Vietnamese adolescents, dental hygienists need to highlight availability of pain control, encourage better performance of personal oral hygiene and recommend dental clinics with sliding fee scales to low-income families. This approach to oral health education may enhance dental health and seeking of regular dental visits. Copyright © 2015 The American Dental Hygienists’ Association.

Full Text Available The paper aims to investigate the relationship between the recent increasingly pattern of Vietnamese migrants in Thailand and migration networks. By surveying 50 Vietnamese migrants in Bangkok, Thailand, the study confirms that migration networks have played a critical role in facilitating migration flows, especially irregular flows from Vietnam to Thailand over the years. It can be reflected by reducing the cost of migration, coping with new working environment and risks during working in Thailand and ensuring the return process for Vietnamese migrants. Moreover, forms of social networks includes personal networks (kinship and friendship networks, and community network (ngườidẫnđường’s network, social media has been also discussed. The study also implies that the người dẫn đường’s networks might contribute to recently emerging issues such as human trafficking and smugglings, which require further research.

Seeking balance between the past and the present: Vietnamese refugee parenting practices and adolescent well-being.

Tingvold, Laila; Hauff, Edvard; Allen, James; Middelthon, Anne-Lise

2012-07-01

This qualitative study examines the resources that Vietnamese refugee parents use in raising their adolescent youth in exile and how they, and their adolescents, regard their experiences of different parenting styles. The study is based on 55 semi-structured interviews and several focus groups performed with a small sample of Vietnamese refugee parents and their adolescent children. Three main themes from the interviews were identified: the role of the extended family and siblings in bringing up children; language acquisition and cultural continuity and, finally, religion and social support. Our findings suggest extended kin are involved in the raising of adolescent children, providing additional family ties and support. Parents regarded Vietnamese language acquisition by their youth as facilitating both communication with extended kin and cultural transmission. Several parents stressed the importance of religious community to socialising and creating a sense of belonging for their youth. Vietnamese refugee parents seek a balance between Vietnamese values and their close extended family social networks, and the opportunities in Norway to develop autonomy in pursuit of educational and economic goals. Together these parenting practices constituted a mobilization of resources in support of their youth. These findings may have important implications for future research on resiliency and the role of these strategies as protective factors mediating mental health outcomes. They may also have implications for treatment, in terms of the types of resources treatment can access and for prevention strategies that maximize key cultural resources for Vietnamese refugee youth.

Uplift history of a transform continental margin revealed by the stratigraphic record: The case of the Agulhas transform margin along the Southern African Plateau

Baby, Guillaume; Guillocheau, François; Boulogne, Carl; Robin, Cécile; Dall'Asta, Massimo

2018-04-01

The south and southeast coast of southern Africa (from 28°S to 33°S) forms a high-elevated transform passive margin bounded to the east by the Agulhas-Falkland Fracture Zone (AFFZ). We analysed the stratigraphic record of the Outeniqua and Durban (Thekwini) Basins, located on the African side of the AFFZ, to determine the evolution of these margins from the rifting stage to present-day. The goal was to reconstruct the strike-slip evolution of the Agulhas Margin and the uplift of the inland high-elevation South African Plateau. The Agulhas transform passive margin results from four successive stages: Rifting stage, from Late Triassic to Early Cretaceous ( 200?-134 Ma), punctuated by three successive rifting episodes related to the Gondwana breakup; Wrench stage (134-131 Ma), evidenced by strike- and dip-slip deformations increasing toward the AFFZ; Active transform margin stage (131-92 Ma), during which the Falkland/Malvinas Plateau drifts away along the AFFZ, with an uplift of the northeastern part of the Outeniqua Basin progressively migrating toward the west; Thermal subsidence stage (92-0 Ma), marked by a major change in the configuration of the margin (onset of the shelf-break passive margin morphology). Two main periods of uplift were documented during the thermal subsidence stage of the Agulhas Margin: (1) a 92 Ma short-lived margin-scale uplift, followed by a second one at 76 Ma located along the Outeniqua Basin and; (2) a long-lasting uplift from 40 to 15 Ma limited to the Durban (Thekwini) Basin. This suggests that the South African Plateau is an old Upper Cretaceous relief (90-70 Ma) reactivated during Late Eocene to Early Miocene times (40-15 Ma).

Cost-effectiveness of breast cancer screening using mammography in Vietnamese women

Science.gov (United States)

2018-01-01

Background The incidence rate of breast cancer is increasing and has become the most common cancer in Vietnamese women while the survival rate is lower than that of developed countries. Early detection to improve breast cancer survival as well as reducing risk factors remains the cornerstone of breast cancer control according to the World Health Organization (WHO). This study aims to evaluate the costs and outcomes of introducing a mammography screening program for Vietnamese women aged 45–64 years, compared to the current situation of no screening. Methods Decision analytical modeling using Markov chain analysis was used to estimate costs and health outcomes over a lifetime horizon. Model inputs were derived from published literature and the results were reported as incremental cost-effectiveness ratios (ICERs) and/or incremental net monetary benefits (INMBs). One-way sensitivity analyses and probabilistic sensitivity analyses were performed to assess parameter uncertainty. Results The ICER per life year gained of the first round of mammography screening was US$3647.06 and US$4405.44 for women aged 50–54 years and 55–59 years, respectively. In probabilistic sensitivity analyses, mammography screening in the 50–54 age group and the 55–59 age group were cost-effective in 100% of cases at a threshold of three times the Vietnamese Gross Domestic Product (GDP) i.e., US$6332.70. However, less than 50% of the cases in the 60–64 age group and 0% of the cases in the 45–49 age group were cost effective at the WHO threshold. The ICERs were sensitive to the discount rate, mammography sensitivity, and transition probability from remission to distant recurrence in stage II for all age groups. Conclusion From the healthcare payer viewpoint, offering the first round of mammography screening to Vietnamese women aged 50–59 years should be considered, with the given threshold of three times the Vietnamese GDP per capita.

Ho-Pham, Lan T; Lai, Thai Q; Nguyen, Nguyen D; Barrett-Connor, Elizabeth; Nguyen, Tuan V

2010-06-01

It has been widely assumed that for a given BMI, Asians have higher percent body fat (PBF) than whites, and that the BMI threshold for defining obesity in Asians should be lower than the threshold for whites. This study sought to test this assumption by comparing the PBF between US white and Vietnamese women. The study was designed as a comparative cross-sectional investigation. In the first study, 210 Vietnamese women ages between 50 and 85 were randomly selected from various districts in Ho Chi Minh City (Vietnam). In the second study, 419 women of the same age range were randomly selected from the Rancho Bernardo Study (San Diego, CA). In both studies, lean mass (LM) and fat mass (FM) were measured by dual-energy X-ray absorptiometry (DXA) (QDR 4500; Hologic). PBF was derived as FM over body weight. Compared with Vietnamese women, white women had much more FM (24.8 +/- 8.1 kg vs. 18.8 +/- 4.9 kg; P or=30, 19% of US white women and 5% of Vietnamese women were classified as obese. Approximately 54% of US white women and 53% of Vietnamese women had their PBF >35% (P = 0.80). Although white women had greater BMI, body weight, and FM than Vietnamese women, their PBF was virtually identical. Further research is required to derive a more appropriate BMI threshold for defining obesity for Asian women.

PRONUNCIATION OF CONSONANTS /ð/ AND /θ/ BY ADULT VIETNAMESE EFL LEARNERS

Directory of Open Access Journals (Sweden)

Thien Sao Bui

2016-07-01

Full Text Available This study examined the pronunciation of consonants /ð/ & /θ/ by adult Vietnamese learners of English. Ten adult Vietnamese learners of English were selected to be the sample for the audiotape observation, which aimed at identifying the participants’ mistakes in pronouncing /ð/ and /θ/. Secondly, 115 learners of English in Vietnam were asked to complete a questionnaire regarding the causes of their pronunciation errors. The findings indicated that substitution phenomenon was a dominant problem in the students’ pronunciation of /θ/ and /ð/. The most outstanding problem in pronouncing the consonant /θ/ was replacing this sound by Vietnamese /t‘/. With regards to /ð/ sound, it was most frequently mispronounced as /z/. Besides, there was a new kind of mistake found: it was the tendency to pronounce /dʒ/ instead of /ð/, which has not been reported ever. Apart from that, participants also confirmed some causes of their erroneous pronunciation. As perceived by the learners themselves, the most popular causes of their problems were the lack of English exposure and practice, which implicated that an effective environment for using English was highly necessary.

Reconstructing Rodinia by Fitting Neoproterozoic Continental Margins

Science.gov (United States)

Stewart, John H.

2009-01-01

Reconstructions of Phanerozoic tectonic plates can be closely constrained by lithologic correlations across conjugate margins by paleontologic information, by correlation of orogenic belts, by paleomagnetic location of continents, and by ocean floor magmatic stripes. In contrast, Proterozoic reconstructions are hindered by the lack of some of these tools or the lack of their precision. To overcome some of these difficulties, this report focuses on a different method of reconstruction, namely the use of the shape of continents to assemble the supercontinent of Rodinia, much like a jigsaw puzzle. Compared to the vast amount of information available for Phanerozoic systems, such a limited approach for Proterozoic rocks, may seem suspect. However, using the assembly of the southern continents (South America, Africa, India, Arabia, Antarctica, and Australia) as an example, a very tight fit of the continents is apparent and illustrates the power of the jigsaw puzzle method. This report focuses on Neoproterozoic rocks, which are shown on two new detailed geologic maps that constitute the backbone of the study. The report also describes the Neoproterozoic, but younger or older rocks are not discussed or not discussed in detail. The Neoproterozoic continents and continental margins are identified based on the distribution of continental-margin sedimentary and magmatic rocks that define the break-up margins of Rodinia. These Neoproterozoic continental exposures, as well as critical Neo- and Meso-Neoproterozoic tectonic features shown on the two new map compilations, are used to reconstruct the Mesoproterozoic supercontinent of Rodinia. This approach differs from the common approach of using fold belts to define structural features deemed important in the Rodinian reconstruction. Fold belts are difficult to date, and many are significantly younger than the time frame considered here (1,200 to 850 Ma). Identifying Neoproterozoic continental margins, which are primarily

As part of an investigation into ways of improving the quality of Soderberg electrodes made in South Africa, a mineralogical, geochemical and petrographical examination was made of some South African anthracites in comparison with anthracites from North Vietnam and Germany. The results of X-ray diffraction on raw and calcined anthracites and the analyses of the macerals in raw anthracites indicated that the sample from North Vietnam, which is an anthracite that is used in Japan for Soderberg-electrode paste, has a very high vitrinite content, low sulphur and phoshorus contents, and, when it has been calcined, contains more graphite than the other samples examined. The samples from the South African collieries, Balgray and Brockwell, contain more sulphur and phosphorus, and much less vitrinite, than the North Vietnamese samples. The anthracite from Natal Anthracite Colliery Ltd contains sulphur and phosphorus in amounts similar to those of the North Vietnamese anthracite, but it has a low vitrinite content. All three South African anthracites contain similar, low amounts of graphite when they have been calcined. The German anthracite, when calcined, contains intermediate amounts of vitrinite and graphite. Chemical analyses of the ash showed that there are major differences in the composition of the ash and the mineralogy of the various anthracites. The results of this preliminary investigation indicate that the most important requisite for graphitisation is a high vitrinite content

To determine the test-retest repeatability of the National Eye Institute 25-item Visual Function Questionnaire (NEI VFQ-25) for use with older Vietnamese adults with bilateral cataract. The questionnaire was translated into Vietnamese and back-translated into English by two independent translators. Patients with bilateral cataract aged 50 and older completed the questionnaire on two separate occasions, one to two weeks after first administration of the questionnaire. Test-retest repeatability was assessed using the Cronbach's α and intraclass correlation coefficients. The average age of participants was 67 ± 8 years and most participants were female (73%). Internal consistency was acceptable with the α coefficient above 0.7 for all subscales and intraclass correlation coefficients were 0.6 or greater in all subscales. The Vietnamese NEI VFQ-25 is reliable for use in studies assessing vision-related quality of life in older adults with bilateral cataract in Vietnam. We propose some modifications to the NEI-VFQ questions to reflect activities of older people in Vietnam. © 2013 ACOTA.

Permian-Triassic thermal anomaly of the active margin of South America as a result of plate kinematics reorganization

Science.gov (United States)

Riel, Nicolas; Jaillard, Etienne; Guillot, Stéphane; Martelat, Jean-Emmanuel; Braun, Jean

2013-04-01

From Permian to Triassic times, tectonic plate reorganization provoked Pangaea breakup, counterclockwise rotation of Gondwana, closing of the Paleo-Tethys Ocean and opening of the Neo-Tethys oceanic realm. Meanwhile, the switch from arc volcanism to widespread S-type magmatism along the western South American active margin around 275-265 Ma is symptomatic of the onset of a large-scale Permian-Triassic thermal anomaly (PTTA)affecting the whole margin. Here we report metamorphic and U-Pb geochronological results from the El Oro metamorphic complex in the forearc zone of southwestern Ecuador, which recorded the last step, at 230-225 Ma, of the PTTA. The change in the drift direction of Gondwana from north to east at ca. 270 Ma was related to plate reorganization and provoked the verticalization of the subducted Panthalassa slab. As the slab verticalized, strong heat advection produced a high heat flow beneath the active margin inducing the development of a huge thermal anomaly responsible for the PTTA, which lasted 30 Ma. This voluminous magmatic activity culminated at the Permian-Triassic boundary, and may have contributed to the degradation of life conditions on the Earth surface.

Because national surveys of people living with psychotic disorders tend to exclude people with low English proficiency (LEP), little is known of their economic and social functioning. Culturally influenced explanatory models may result in delayed presentation and poorer functioning. The study aimed to compare the functioning of LEP Vietnamese-Australian and Australian-born patients with psychosis and to investigate the Vietnamese-Australians' pathways to care. In all, 19 LEP Vietnamese-Australians, previously excluded from the Australian Survey of High Impact Psychosis (SHIP), were matched with 15 Australian-born controls, and interviewed by a Vietnamese bilingual mental health professional using the SHIP Interview Schedule. The Vietnamese-Australian patients were significantly more likely to live with family, rate spirituality as important and participate in community rehabilitation programs. Their work, social and independent functioning, was better than the controls. The groups did not differ in mental health services received and satisfaction with services. Although half of Vietnamese-Australians attributed mental illness to supernatural, among other causes, none had consulted traditional healers. Despite LEP, Vietnamese-Australians with psychosis showed comparable or better functioning than Australian-born patients. Further investigation is recommended into LEP patients' clinical and social recovery and the role of language communities' support networks. © The Author(s) 2014.

"Freedom. Money. Fun. Love.": the warlore of Vietnamese bargirls.

Memories of the Vietnam War abound in the minds of those who survived it, be they veterans or civilians, Vietnamese or American. Vietnamese refugees, forced to flee their homeland after the war ended in 1975, tell particularly poignant stories of loss -- of country, of family, of tradition, and of identity. Not so the women featured in this article. During the war, they served as bargirls in Saigon, entertaining American soldiers. The stories they tell of the war paint an entirely different picture: one of good times, and camaraderie, and the exhilaration of being young and free in the city. They were able to break free from tradition and the expectations imposed on their gender because of the war, and because of that, remember the war as the best time of their lives.

Accumulation of deformation at convergent plate margins is recently identified to be highly discontinuous and transient in nature: silent slip events, non-volcanic tremors, afterslip, fault coupling and complex response patterns of the upper plate during a single event as well as across several seismic cycles have all been observed in various settings and combinations. Segments of convergent plate margins with high recurrence rates and at different stages of the rupture cycle like the Chilean margin offer an exceptional opportunity to study these features and their interaction resolving behaviour during the seismic cycle and over repeated cycles. A past (TIPTEQ) and several active international initiatives (Integrated Plate Boundary Observatory Chile; IPOC-network.org) address these goals with research groups from IPG Paris, Seismological Survey of Chile, Free University Berlin, Potsdam University, Hamburg University, IFM-GEOMAR Kiel, GFZ Potsdam, and Caltech (USA) employing an integrated plate boundary observatory and associated projects. Results from these studies allow us to define the preseismic state - with respect to the Maule eartghquake - of the margin system at the south Central Chilean convergent margin. Here, two major seismic events have occurred in adjoining segments (Valdivia 1960, Mw = 9.5; Maule 2010, Mw = 8.8) yielding observations from critical time windows of the seismic cycle in the same region. Seismic imaging and seismological data have allowed us to relocate major rupture hypocentres and to locate the geometry and properties of the seismogenic zone. The reflection seismic data exhibit well defined changes of reflectivity and Vp/Vs ratio along the plate interface that can be correlated with different parts of the coupling zone and its hanging wall as well as with changes during the seismic cycle. Observations suggest an important role of the hydraulic system, and of lateral variation of locking degree on subsequent rupture and aftershock

Overdose beliefs and management practices among ethnic Vietnamese heroin users in Sydney, Australia

Directory of Open Access Journals (Sweden)

Maher Lisa

2009-04-01

Full Text Available Abstract Background Ethnic Vietnamese injecting drug users (IDUs in Australia draw on a range of beliefs and etiologic models, sometimes simultaneously, in order to make sense of health and illness. These include understandings of illness as the result of internal imbalances and Western concepts of disease causation including germ/pollution theory. Methods Observational fieldwork and in-depth interviews were conducted between 2001 and 2006 in neighbourhoods characterised by high proportions of Asian background IDUs and street-based drug markets. Eligibility criteria for the study were: 1 ethnic Vietnamese cultural background; 2 aged 16 years and over and; 3 injected drugs in the last 6 months. Results Participants commonly attempted to treat heroin overdose by withdrawing blood (rút máu from the body. Central to this practice are cultural beliefs about the role and function of blood in the body and its relationship to illness and health. Participants' beliefs in blood were strongly influenced by understandings of blood expressed in traditional Chinese and Vietnamese medicine. Many participants perceived Western drugs, particularly heroin, as "hot" and "strong". In overdose situations, it was commonly believed that an excessive amount of drugs (particularly heroin entered the bloodstream and traveled to the heart, making the heart work too hard. Withdrawing blood was understood to reduce the amount of drugs in the body which in turn reduced the effects of drugs on the blood and the heart. Conclusion The explanatory model of overdose employed by ethnic Vietnamese IDUs privileges traditional beliefs about the circulatory, rather than the respiratory, system. This paper explores participants' beliefs about blood, the effects of drugs on blood and the causes of heroin overdose in order to document the explanatory model of overdose used by ethnic Vietnamese IDUs. Implications for overdose prevention, treatment and management are identified and

Page, Randy M; Huong, Nguyen Thanh; Chi, Hoang Khanh; Tien, Truong Quang

2012-01-01

Tobacco-related deaths in Vietnam are forecast to climb from 40 000 annually to 70 000 by 2030. Previous research in Western nations has found social factors to be important determinants of adolescent smoking. Because these factors remain unexplored in Vietnamese youth, the purpose of this study was to examine social normative beliefs regarding smoking in a school-based sample of North Vietnamese adolescents and the association of these factors with smoking behavior and susceptibility to smoking. Three measures of normative beliefs regarding smoking were evaluated in cross-sectional surveys of secondary students. Of the 3 measures, parent/peer disapproval was the most consistent normative belief associated with smoking behavior and susceptibility to smoking. Youth smoking prevention programs should consider assessing and taking into account normative beliefs and develop strategies that provide accurate information about the actual prevalence of smoking, the types of individuals who smoke, and approval/disapproval of smoking by parents and peers.

Acculturation and Psychological Adjustment of Vietnamese Refugees: An Ecological Acculturation Framework.

Science.gov (United States)

Salo, Corrina D; Birman, Dina

2015-12-01

Acculturation to the culture of the host society as well as to one's heritage culture have been shown to impact immigrants' adjustment during the years following resettlement. While acculturation has been identified as an important factor in adjustment of Vietnamese immigrants (Birman and Tran in Am J Orthopsychiatr 78(1):109-120. doi: 10.1037/0002-9432.78.1.109 , 2008), no clear pattern of findings has emerged and too few studies have employed an ecological approach. The purpose of this paper is to contextualize the study of acculturation and adjustment by taking an ecological approach to exploring these relationships across several life domains, using a bilinear scale, and examining mediators of these relationships for adult Vietnamese refugees (N = 203) in the United States. We call this approach the Ecological Acculturation Framework (EAF). Results of a structural equation model (SEM) showed that job satisfaction fully mediated the relationship between American acculturation and psychological distress, demonstrating that this relationship was specific to an occupational domain. However, while Vietnamese acculturation predicted co-ethnic social support satisfaction, it did not predict reduced psychological distress. Implications for a life domains approach, including domain specificity, are discussed.

Determinants of capital structure: An empirical study on Vietnamese listed firms

Directory of Open Access Journals (Sweden)

Le Trung Thanh

2017-05-01

Full Text Available This paper aims to explore the capital structure of listed Vietnamese companies in an updated context of financial development (the recent situation of domestic equity and debt capital market. By applying Random Effect model for panel data, we analyze 05 firm-specific and 01 country-specific determinants of capital structure based on the data set of 228 firms listed on Ho Chi Minh Stock Exchange during the period 2010 – 2014. The results indicated that The Pecking Order theory better explains the financing behaviors of Vietnamese listed firms. Accordingly, although in recent years, Vietnam’s equity market and corporate debt capital market have evolved considerably, the capital structure of Vietnamese companies are still dominated by the use of short-term financing sources. High-growth firms or large-sized firms still rely heavily on external debt rather than equity issuance while State-owned enterprises (SOE are reported to have positive association with the use of long-term financing sources. This study proposed some recommendations to the policymakers in two dimensions: improving the efficiency and role of capital markets to mitigate the reliance on short-term funds and ensuring that bank finance is allocated on a commercial basis.

Measuring the impact of marginal tax rate reform on the revenue base of South Africa using a microsimulation tax model

Directory of Open Access Journals (Sweden)

Yolande Jordaan

2015-08-01

Full Text Available This paper is primarily concerned with the revenue and tax efficiency effects of adjustments to marginal tax rates on individual income as an instrument of possible tax reform. The hypothesis is that changes to marginal rates affect not only the revenue base, but also tax efficiency and the optimum level of taxes that supports economic growth. Using an optimal revenue-maximising rate (based on Laffer analysis, the elasticity of taxable income is derived with respect to marginal tax rates for each taxable-income category. These elasticities are then used to quantify the impact of changes in marginal rates on the revenue base and tax efficiency using a microsimulation (MS tax model. In this first paper on the research results, much attention is paid to the structure of the model and the way in which the database has been compiled. The model allows for the dissemination of individual taxpayers by income groups, gender, educational level, age group, etc. Simulations include a scenario with higher marginal rates which is also more progressive (as in the 1998/1999 fiscal year, in which case tax revenue increases but the increase is overshadowed by a more than proportional decrease in tax efficiency as measured by its deadweight loss. On the other hand, a lowering of marginal rates (to bring South Africa’s marginal rates more in line with those of its peers improves tax efficiency but also results in a substantial revenue loss. The estimated optimal individual tax to gross domestic product (GDP ratio in order to maximise economic growth (6.7 per cent shows a strong response to changes in marginal rates, and the results from this research indicate that a lowering of marginal rates would also move the actual ratio closer to its optimum level. Thus, the trade-off between revenue collected and tax efficiency should be carefully monitored when personal income tax reform is being considered.

Operational Efficiency of Bank Loans and Deposits: A Case Study of Vietnamese Banking System

Directory of Open Access Journals (Sweden)

Tram Nguyen

2018-01-01

Full Text Available This paper examines whether there is a causal relationship between bank loans and deposits in the Vietnamese banking system and the efficiency of the use of loans and deposits by the Vietnamese banks. In a country such as Vietnam, where inter-bank money markets are relatively underdeveloped, one would expect a reasonably strong relationship between deposits and loans. A pooled cross-sectional sample of financial ratios is collected from annual reports of 44 Vietnamese banks covering the period 2008–2015. The explanatory power of instrumental variables in relation to the endogenous variables is tested. A deterministic frontier model based on corrected ordinary least squares, estimated by three-stage least squares on a simultaneous equations model, is employed to derive the frontiers for the sampled banks as well as to estimate the causality between bank loans and deposits. Our findings suggest that, in an underdeveloped banking system such as Vietnam, bank deposits have a positive and significant impact on bank loans, but the reverse relationship is not significant. It is further suggested that in deposit-taking and loan-creating activities, Vietnamese banks performed moderately well over the period examined; however, in the near future, they should start to focus more on deposit-taking activities.

Quach, Thu; Nguyen, Kim-Dung; Doan-Billings, Phuong-An; Okahara, Linda; Fan, Cathyn; Reynolds, Peggy

2008-10-01

In recent decades, the nail salon industry has been one of the fastest growing in the U.S. California has over 300,000 workers licensed to perform nail care services. Though little is known about their health, these workers routinely handle cosmetic products containing carcinogens and endocrine disruptors that may increase a woman's breast cancer risk. Additionally, an estimated 59-80% of California nail salons are run by Vietnamese women who face socio-cultural barriers that may compromise their workplace safety and health care access. In a pilot project designed to characterize Vietnamese nail salon workers in Alameda County, California in order to inform future health interventions and reduce occupational exposures, we conducted face-to-face surveys with a convenience sample of 201 Vietnamese nail salon workers at 74 salons. Of the workers surveyed, a majority reported that they are concerned about their health from exposure to workplace chemicals. Additionally, a sizeable proportion reported having experienced some health problem after they began working in the industry, particularly acute health problems that may be associated with solvent exposure (e.g. skin and eye irritation, breathing difficulties and headaches). Our findings highlight a critical need for further investigation into the breast cancer risk of nail salon workers, underscored by the workers' routine use of carcinogenic and endocrine-disrupting chemicals, their prevalent health concerns about such chemicals, and their high level of acute health problems. Moreover, the predominance of Vietnamese immigrant women in this workforce makes it an important target group for further research and health interventions.

In general, over the course of the time, the phenomenon of acceleration in physical development may be observed, i.e. the children and adults of the next generation are taller and heavier than in former generation. Our data presented in this paper show a regular trend of acceleration in the development on Vietnamese, but the trend is still slow and was mostly probably influenced by our difficulties in a long time of war. It is hoped that, the acceleration in the development may be increased in the future following the economical acceleration of our country, however it is known that the ratio between the length of different parts of human body is a specific characteristic for human race, sex and group age. Therefore we may estimate these ratio for the prolongation of the utilization of our measured physical data. The result of studies on water balance of Vietnamese living in comfortable environment air temperature conditions and working in hot environment with different levels of energy expenditure and the elemental composition of sweat of workers in hot environment are also presented as well as the mass of major internal organs of Vietnamese. The data of food consumption in Viet Nam National institute of Nutrition (1986) show an unbalanced state and deficient food intake in the nutrition of Vietnamese. However, after economical reconstruction in the last years the data of food consumption and food supply are varied. The quantity of protein, fat and milk products increase every time in people's food. (author)

Secondary education among lower caste adolescent girls living in rural Karnataka, South India, is characterized by high rates of school drop-out and absenteeism. A cross-sectional baseline survey (N=2275) was conducted in 2014 as part of a cluster-randomized control trial among adolescent girls (13-14 year) and their families from marginalized communities in two districts of north Karnataka. Bivariate and multivariate logistic regression models were used. Overall, 8.7% girls reported secondary school dropout and 8.1% reported frequent absenteeism (past month). In adjusted analyses, economic factors (household poverty; girls' work-related migration), social norms and practices (child marriage; value of girls' education), and school-related factors (poor learning environment and bullying/harassment at school) were associated with an increased odds of school dropout and absenteeism. Interventions aiming to increase secondary school retention among marginalized girls may require a multi-level approach, with synergistic components that address social, structural and economic determinants of school absenteeism and dropout.

Asian ethnic subgroups are often treated as a single demographic group in studies looking at cancer screening and health disparities. To evaluate knowledge and health beliefs associated with colorectal cancer (CRC) and CRC screening among Chinese, Korean, and Vietnamese subgroups, a survey assessed participants' demographic characteristics, healthcare utilization, knowledge, beliefs, attitudes associated with CRC and CRC screening. Exploratory factor analysis identified six factors accounting >60 % of the total variance in beliefs and attitudes. Cronbach's alpha coefficients assessed internal consistency. Differences among Asian subgroups were assessed using a Chi square, Fisher's exact, or Kruskal-Wallis test. Pearson's correlation coefficient assessed an association among factors. 654 participants enrolled: 238 Chinese, 217 Korean, and 199 Vietnamese. Statistically significant differences existed in demographic and health care provider characteristics, knowledge, and attitude/belief variables regarding CRC. These included knowledge of CRC screening modalities, reluctance to discuss cancer, belief that cancer is preventable by diet and lifestyle, and intention to undergo CRC screening. Chinese subjects were more likely to use Eastern medicine (52 % Chinese, 25 % Korean, 27 % Vietnamese; p Vietnamese; p Vietnamese subjects were less likely to consider CRC screening (95 % Chinese, 95 % Korean, 80 % Vietnamese; p < 0.0001). Important differences exist in knowledge, attitudes, and health beliefs among Asian subgroups. Understanding these differences will enable clinicians to deliver tailored, effective health messages to improve CRC screening and other health behaviors.

Han, Meekyung; Cao, Lien; Anton, Karen

2015-01-01

Vietnamese Americans are at high risk for developing mental health disorders due to multiple risk factors such as trauma and acculturative stress. However, the utilization of mental health services has been low. The pilot project Tam An was implemented to raise mental health awareness by engaging community resources in the Vietnamese population. Informed by the Community Readiness Model and through local ethnic media sources, messages to destigmatize mental health and promote the willingness to initiate mental health treatment were presented. Using an exploratory perspective, findings from focus group data suggest that the project improved the community's stage of readiness.

Axiological Background of Vietnamese Students Adaptability

Directory of Open Access Journals (Sweden)

Сергей Иванович Кудинов

2018-12-01

Full Text Available This article analyzes the ratio of axiological orientation of Vietnamese students and their adaptability. The article demonstrates that the ratio of certain values, attitudes and needs forms a specific type of axiological orientation. The article finds out that the different types of orientation are interrelated with the selective personality adaptive indicators of Vietnamese students and can be regarded as predictors of the adaptation process. The article identifies the current trends of adaptability studies within the context of the system paradigm. The article points out the main determinants of the personal adaptability manifestations. The methodological basis of the research was the dispositional concept of personality and individual traits investigation by A.I. Krupnov, as well as the provisions of the theory of personal potential by D.A. Leontiev, developed within the framework of positive psychology. The aim of the study presented in this article is to identify the relationship between the indicators of axiological orientation and adaptability variables in Vietnamese students. At the first stage of the study, different types of students’ axiological orientation based on the results of cluster analysis have been identified and described: vocational-career, egocentric, socio-communicative orientation types. Statistically significant differences between the selected types were recorded for most of the components. The meaningful characteristics of these types at the behavioral level differ in their attitude to training activities, relationship with other people and personal self-conception. At the next stage the features of adaptability among the representatives with different types of axiological orientation were revealed. The correlation analysis was used to identify the correlation between the axiological variables and adaptability. It turned out that all the three groups are pressed by uncertainty, nostalgia and asthenic feelings. At

Menges, Daniel; Glasmacher, Ulrich Anton; Hackspacher, Peter; Schneider, Gabriele; Salomon, Eric

2015-04-01

The Kaoko Belt in northwestern Namibia originates in the collision of the Rio de la Plata and Kongo Craton during the Pan-African Orogeny in the Neoproterozoic (1) and represents the northern arm of the Damara Orogen. NW-Namibias continental crust mainly consists of the NE-SW striking intracontinental branch of the Pan-African Damara mobile belt, which separates the Congo from the Kalahari craton. The Damara Orogen is divided into several tectonostratigraphic zones that are bounded by steeply dipping, ductile shear zones. These regional lineaments can be traced at least 150 km offshore (2). The lithostratigraphic units consist of Proterozoic and Cambrian metamorphosed rocks (534 (7) Ma - 481 (25) Ma (3) as well as Mesozoic sedimentary and igneous rocks. From Permo-Carboniferous to Mid Jurassic northern Namibia was affected by deep erosion of the Damara Orogen, Permo-Triassic collisional processes along the southern margin of Gondwana and eastern margin of Africa (4), and the deposition of the Nama Group sediments and the Karoo megasequence (5). Between the Otjihorongo and the Omaruru Lineament-Waterberg Thrust early Mesozoic tectonic activity is recorded by coarse clastic sediments deposited within NE trending half-graben structures. The Early Jurassic Karoo flood basalt lavas erupted rapidly at 183±1 Ma (6). The Early Cretaceous Paraná-Etendeka flood basalts (132±1 Ma) and mafic dike swarms mark the rift stage of the opening of the South Atlantic (7). Early Cretaceous alkaline intrusions (137-124 Ma) occur preferentially along Mesozoic half-graben structures and are called the Damaraland Igneous Province (8). Late Cretaceous alkaline intrusions and kimberlite pipes occur in northern Namibia. Post Early Paleocene siliciclastic sedimentation in Namibia was largely restricted to a 150 km wide zone (9) and is represented by the Tsondab Sandstone Formation (~ 300 m thickness). The oldest part has an age of early Paleocene and the upper part span from middle Miocene

Objective The aim of the Vietnamese Dementia talking-book was to address low health literacy in older people of Vietnamese background living with dementia through the provision of an online resource to help individuals, their families and carers better understand and manage this condition and provide information about available dementia services. Design This qualitative study used codesign and participatory action research to develop and refine the talking-book in consultation with expert stakeholders, a consumer advocacy group and the Vietnamese community to assess its utility and ensure cultural and linguistic appropriateness and relevance. Participants 59 members of the Vietnamese community, 11 stakeholders from community health services and ethnic agencies, consumer advocacy groups and the research team participated in the codesign and refinement of the talking-book. 22 members of the Vietnamese community appraised the final product. Setting Vietnamese community planned activity groups in the Western, Northern and Southern suburbs of Melbourne, Australia. Results Our codesign study outlines the process required to develop a Vietnamese Dementia Talking-Book resource partnering with consumers and expert stakeholders to identify consumer need, selection of the content and appropriate language level, construction of the book, measuring acceptability of the talking-book, modification based on feedback and production and dissemination. Feedback on the final version of the talking-book revealed widespread consensus that the book enhanced the knowledge of members of the Vietnamese community in regard to understanding dementia and navigation and accessing of available services. Conclusions This free internationally available online Vietnamese Dementia Talking-Book facilitates improved dementia-related health literacy in the Vietnamese community. The book also serves as a tool to facilitate the provision of care to Vietnamese people living with memory loss by assisting

A tectonic reconstruction of accreted terranes along the paleo-Pacific margin of Gondwana

Science.gov (United States)

Bammel, Brandon

The southern oceanic margin of Gondwana was nearly 40,000 km long or 24,854.8 miles. The southern margin was the result of the Terra Australis orogen. Spanning 18,000 km or 11,184.7 miles and is proposed as one of the largest and longest lived orogens in Earth history. The paleo-Pacific margin of Gondwana consisted of segments of the Australian-Antarctic craton, southern South America (modern Argentina and Chile), southern South Africa, Marie Byrdland, New Zealand and its adjacent continental shelf, the Ellsworth Mountains, and the Transantarctic Mountains. The process of terrane accretion has played a substantial part in the assembly of the continents as they look today. The paleo-Pacific margin of Gondwana was an active region of terrane accretion from the Neoproterozoic to the Late Mesozoic. This research study examines the accretion of terranes across the paleo-Pacific Gondwana margin to provide a comprehensive reconstruction. A paleogeographic basemap was created using PALEOMAP Project maps and the geology data was provided by the School of Geoscience from the University of Witwatersrand of South Africa. Location and data analyzed for terranes were collected building a PDF library of journal articles across numerous geological publications.

Functional impairment and mental health functioning among Vietnamese children.

Dang, Hoang-Minh; Weiss, Bahr; Trung, Lam T

2016-01-01

Functional impairment is a key indicator of need for mental health services among children and adolescents, often a stronger predictor of service usage than mental health symptoms themselves. Functional impairment may be of particular importance in low- and middle-income countries (LMIC) because of its potential to focus policy on treatment of child mental health problems which is generally given low priority in LMIC. However, few studies have assessed functional impairment in LMIC. The present study assessed rates of functional impairment among children in Vietnam, as a case example of an LMIC, as well as effects of other risk/protective factors of particular relevance to LMIC (e.g., whether the family lived in an urban or rural area; family structure variables such as grandparents living with the family). 1314 parents of children 6-16 years old from 10 Vietnamese provinces were interviewed. The overall rate of functional impairment among Vietnamese children was 20 %, similar to rates in high-income countries such as Germany and the United States, suggesting that LMIC status may not be associated with dramatic increases in functional impairment in children. Functional impairment was significantly greater among mental health cases than non-cases, with increases of over 550 % associated with mental health caseness. A number of other risk factors (e.g., marital status) had smaller but significant effects. Mental health problems are a major but not the sole contributor to functional impairment among Vietnamese children. The pragmatic significance of this research lies in its potential to affect public awareness and policy related to child mental health in LMIC.

East Meets West: The Adaptation of Vietnamese International Students to California Community Colleges

Directory of Open Access Journals (Sweden)

Tam Huu Do

2007-01-01

Full Text Available This study explores seven adaptation aspects that include language and communication, cultural awareness, loneliness and isolation, new educational settings, financial concerns, gender-based differences, and the political impact of the anti-communist Vietnamese American community. Based on Person/Environment Interactionism theory, case studies of eight students from Vietnam at two Southern California community colleges are considered utilizing data derived from weekly diaries, individual interviews, a final group meeting, and academic records. The students’ prior assumptions and expectations are identified and their coping strategies to various adaptation issues are documented and analyzed. The ethnic diversity of Orange County generally facilitated the students’ adaptation efforts in the aspects of language and communications, cultural awareness, and loneliness and isolation. The students seemed to readily adapt to the new educational settings and excel academically despite some different educational practices. There were no apparent gender-based differences in the students’ adaptation. However, unwelcoming attitudes from the anti-communist members of the Vietnamese American community adversely impacted the international students’ socialization with Vietnamese Americans, but did not impact their academic performance.

Vaccination data for Asian Americans are comparable to those for whites, possibly because they are reported in aggregate rather than for subgroups. We compared influenza and pneumococcal vaccination rates among eligible Asian Americans and white Americans, and for Vietnamese Americans as a subgroup, and assessed factors associated with these vaccinations. Cross-sectional study of data collected from three ethnic groups over 4 years by telephone survey. Data were weighted for selection probability and population estimates and analyzed by multivariate logistic regression. Vietnamese Americans had a higher rate of influenza vaccination (61%) than Asian Americans (45%) and white Americans (52%), and lower rate of pneumococcal vaccination (41%) than Asian Americans (56%), both lower than white Americans (67%). When analyzed as a subgroup, Vietnamese Americans had a higher influenza vaccination rate, but a lower pneumococcal vaccination rate, compared to Asian Americans and white Americans, which may indicate that health behaviors and outcomes can differ widely among Asian subgroups. Analyses of preventive care measures in Asian Americans should focus on subgroups to ensure accuracy and quality of assessments.

We investigated whether pre-germinated brown rice bran extract containing acylated steryl glucosides (PSG) reduces the risk of atherosclerosis in post-menopausal Vietnamese women. A total of 60 post-menopausal Vietnamese women (45-65 y old) with high LDL cholesterol levels (over 140 mg/dL) were randomly divided into PSG (n=30) and placebo (n=30) groups. The subjects in the PSG group were assigned a daily intake of 6 capsules containing 50 mg PSG, and the subjects in the placebo group were assigned a daily intake of 6 capsules containing corn oil for 6 mo. Before baseline and after month 2, month 4, and month 6 of the intervention, we conducted anthropometric measurements, blood biochemical examinations, a nutrition survey, and physical activity, flow-mediated dilation (FMD), and cardio-ankle vascular index (CAVI) measurements. Serum LDL cholesterol concentrations were significantly reduced from 163.6±25.3 (mg/dL) to 135.9±26.8 (mg/dL) compared to the placebo group (pVietnamese women with high LDL cholesterol.

Orogenic structural inheritance and rifted passive margin formation

Science.gov (United States)

Salazar Mora, Claudio A.; Huismans, Ritske S.

2016-04-01

Structural inheritance is related to mechanical weaknesses in the lithosphere due to previous tectonic events, e.g. rifting, subduction and collision. The North and South Atlantic rifted passive margins that formed during the breakup of Western Gondwana, are parallel to the older Caledonide and the Brasiliano-Pan-African orogenic belts. In the South Atlantic, 'old' mantle lithospheric fabric resulting from crystallographic preferred orientation of olivine is suggested to play a role during rifted margin formation (Tommasi and Vauchez, 2001). Magnetometric and gravimetric mapping of onshore structures in the Camamu and Almada basins suggest that extensional faults are controlled by two different directions of inherited older Brasiliano structures in the upper lithosphere (Ferreira et al., 2009). In the South Atlantic Campos Basin, 3D seismic data indicate that inherited basement structures provide a first order control on basin structure (Fetter, 2009). Here we investigate the role of structural inheritance on the formation of rifted passive margins with high-resolution 2D thermo-mechanical numerical experiments. The numerical domain is 1200 km long and 600 km deep and represents the lithosphere and the sublithospheric mantle. Model experiments were carried out by creating self-consistent orogenic inheritance where a first phase of orogen formation is followed by extension. We focus in particular on the role of varying amount of orogenic shortening, crustal rheology, contrasting styles of orogen formation on rifted margin style, and the time delay between orogeny and subsequent rifted passive formation. Model results are compared to contrasting structural styles of rifted passive margin formation as observed in the South Atlantic. Ferreira, T.S., Caixeta, J.M., Lima, F.D., 2009.

2013-01-01

Full Text Available This paper extends recent investigations into risk contagion effects on stock markets to the Vietnamese stock market. Daily data spanning October 9, 2006 to May 3, 2012 are sourced to empirically validate the contagion effects between stock markets in Vietnam, and China, Japan, Singapore, and the US. To facilitate the validation of contagion effects with market-related coefficients, this paper constructs a bivariate EGARCH model of dynamic conditional correlation coefficients. Using the correlation contagion test and Dungey et al.’s (2005 contagion test, we find contagion effects between the Vietnamese and four other stock markets, namely Japan, Singapore, China, and the US. Second, we show that the Japanese stock market causes stronger contagion risk in the Vietnamese stock market compared to the stock markets of China, Singapore, and the US. Finally, we show that the Chinese and US stock markets cause weaker contagion effects in the Vietnamese stock market because of stronger interdependence effects between the former two markets.

Exploring Quality Teaching of Information and Communication Technology in New South Wales and Yenbai High Schools: A Comparative Case Study

Science.gov (United States)

Tran, Manh Thang

This study compares ICT policy and curriculum and assessment practices between Australian and Vietnamese secondary schools, and investigates differences between these two school systems. Document analyses and case studies were used to examine the key differences in ICT curriculum and policy and assessment practices between Australian and Vietnamese secondary schools. The document analyses focused on the intended ICT policy and curriculum and assessment, as presented in official documents in both countries. Using a case study approach for in-depth examination, two secondary schools were selected (one from Yenbai province, Vietnam and one from Sydney, New South Wales, Australia). Two principals and three teachers were interviewed. Classroom teaching and assessment practices were observed, and principals and teachers' views were obtained through semi-structured interviews and extensive discussions. Findings from the two case studies were compared with the findings from the document analysis. This study explored and analysed differences in ICT teaching, learning, assessment, and achievement between Vietnamese and Australian secondary students. It was found that that Australian ICT school curricula and assessment differed markedly from the Vietnamese system. Student ICT achievement in these Australian and Vietnamese schools could not only be attributed to higher standards of intended ICT curricula and assessment, or teacher knowledge or classroom practices. These differences are better explained by economic and cultural factors, ICT policies and their degrees of implementation, and extra ICT curricula. In order to bridge the gap and implement adequate ICT curricula and policies, rigorous professional training in teaching and assessment is essential for both Australian and Vietnamese teachers. In order to improve Australian students' ICT achievement, achievement motivation must be addressed. Many challenging aspects were found in ICT policies and classrooms in the

Full Text Available Objective The purpose of this community-based study was to determine factors associated with hepatitis B virus (HBV screening compliance and non-compliance among Chinese, Korean, Vietnamese and Cambodian adults with varying levels of English language proficiency. Methods A cross-sectional design was used consisting of a sample of 1,603 Asian adult men and women. Results Overall, 71.4% of the sample reported having never been screened and 28.6% reported being screened for HBV Demographic, acculturation, and barrier factors were differentially associated with screening rates among the subgroups. Demographic factors associated with never-screened were: lower education, younger age, being male, and no insurance for Chinese; lower education, lower income and no insurance for Cambodians; younger age and unmarried for Koreans; and no health insurance for Vietnamese; Acculturation factors associated with never-screened were: not speaking English for Chinese; not speaking English, not reading newspapers in English, and watching TV in one's native language for Cambodians; not speaking English for Koreans; while no significant factors were found for Vietnamese. All barriers were associated with never-screened for Cambodians and Chinese. Those who lacked knowledge about HBV and had language and transportation barrier were more likely to be never-screened for Koreans. There were no significant relationships between the barriers and the screening status for Vietnamese. Conclusions High incidence of HBV and liver cancer in Asian Americans mandates a more vigorous and more culturally and linguistically appropriate educational effort to increase screening and vaccination for HBV in these underserved and mostly uninsured populations.

VIETNAMESE MIGRATION IN THE CONTEXT OF CLIMATE CHANGE

Directory of Open Access Journals (Sweden)

Artem S. Lukyanetz

2014-01-01

Full Text Available The paper examines emigration from Vietnam in the context of global climate change. Vietnam is among the five countries, most vulnerable to water level rise in the oceans associated with global warming. The areas of potential flooding include territories with most dense population and are extremity important for the economy of Vietnam. The country has a significant demographic potential exceeding 90 mln people. Vietnamese migration has a relatively long history. Large Vietnamese communities have grown in the countries of Eastern Europe; these communities are relatively well integrated into the host countries. Increase in global mean temperatures could lead to severe storms, tsunamis, and flooding and force significant portion of the population out of the Mekong Delta regions and Central provinces of Vietnam. The paper discusses the potential of Atlas Information Systems (AISs for the assessment of social-economic and demographic consequences of climate change in Vietnam. The authors describe an AIS they are developing. This AIS consists of blocks that provide for a close link between socio-political, economic (production, natural resource, and environmental components for the integrated assessment of the provinces of Vietnam. Simulation of events shows that the flood zone could affect such populated provinces as An Giang, Kien Giang, Hau Giang, Dong Thap, Long An, Tien Giang, Vinh Long and Can Tho. To address this problem, the Vietnamese authorities, in 2008, approved the state target program to respond to climate change. The Ministry of Natural Resources and Environment was commissioned to create a scenario of climate change and sea level rise in Vietnam. However, the problem requires an immediate response at the international level, as the threat cannot be localized within the borders of Vietnam. Flooding may require mandatory relocation of the population in the country and, possibly, beyond its borders. If people are not relocated gradually

Lithosphere structure and subsidence evolution of the conjugate S-African and Argentine margins

The bathymetric evolution of the South Atlantic passive continental margins is a matter of debate. Though it is commonly accepted that passive margins experience thermal subsidence as a result of lithospheric cooling as well as load induced subsidence in response to sediment deposition it is disputed if the South Atlantic passive margins were affected by additional processes affecting the subsidence history after continental breakup. We present a subsidence analysis along the SW African margin and offshore Argentina and restore paleobathymetries to assess the subsidence evolution of the margin. These results are discussed with respect to mechanisms behind margin evolution. Therefore, we use available information about the lithosphere-scale present-day structural configuration of these margins as a starting point for the subsidence analysis. A multi 1D backward modelling method is applied to separate individual subsidence components such as the thermal- as well as the load induced subsidence and to restore paleobathymetries for the conjugate margins. The comparison of the restored paleobathymetries shows that the conjugate margins evolve differently: Continuous subsidence is obtained offshore Argentina whereas the subsidence history of the SW African margin is interrupted by phases of uplift. This differing results for both margins correlate also with different structural configurations of the subcrustal mantle. In the light of these results we discuss possible implications for uplift mechanisms.

Circum-Pacific accretion of oceanic terranes to continental blocks: accretion of the Early Permian Dun Mountain ophiolite to the E Gondwana continental margin, South Island, New Zealand

Science.gov (United States)

Robertson, Alastair

2016-04-01

Accretionary orogens, in part, grow as a result of the accretion of oceanic terranes to pre-existing continental blocks, as in the circum-Pacific and central Asian regions. However, the accretionary processes involved remain poorly understood. Here, we consider settings in which oceanic crust formed in a supra-subduction zone setting and later accreted to continental terranes (some, themselves of accretionary origin). Good examples include some Late Cretaceous ophiolites in SE Turkey, the Jurassic Coast Range ophiolite, W USA and the Early Permian Dun Mountain ophiolite of South Island, New Zealand. In the last two cases, the ophiolites are depositionally overlain by coarse clastic sedimentary rocks (e.g. Permian Upukerora Formation of South Island, NZ) that then pass upwards into very thick continental margin fore-arc basin sequences (Great Valley sequence, California; Matai sequence, South Island, NZ). Field observations, together with petrographical and geochemical studies in South Island, NZ, summarised here, provide evidence of terrane accretion processes. In a proposed tectonic model, the Early Permian Dun Mountain ophiolite was created by supra-subduction zone spreading above a W-dipping subduction zone (comparable to the present-day Izu-Bonin arc and fore arc, W Pacific). The SSZ oceanic crust in the New Zealand example is inferred to have included an intra-oceanic magmatic arc, which is no longer exposed (other than within a melange unit in Southland), but which is documented by petrographic and geochemical evidence. An additional subduction zone is likely to have dipped westwards beneath the E Gondwana margin during the Permian. As a result, relatively buoyant Early Permian supra-subduction zone oceanic crust was able to dock with the E Gondwana continental margin, terminating intra-oceanic subduction (although the exact timing is debatable). The amalgamation ('soft collision') was accompanied by crustal extension of the newly accreted oceanic slab, and

The Argentine margin presents a strong segmentation with considerable strike-slip movements along the fracture zones. We focus on the volcanic segment (between the Salado and Colorado transfer zones), which is characterized by seaward dipping reflectors (SDR) all along the ocean-continent transition [e.g. Franke et al., 2006; Gladczenko et al., 1997; Hinz et al., 1999]. The segment is structured by E-W trending basins, which differs from the South African margin basins and cannot be explained by classical models of rifting. Thus the study of the relationship between the basins and the Argentine margin itself will allow the understanding of their contemporary development. Moreover the comparison of the conjugate margins suggests a particular evolution of rifting and break-up. We firstly focus on the Colorado Basin, which is thought to be the conjugate of the well studied Orange Basin [Hirsch et al., 2009] at the South African margin [e.g. Franke et al., 2006]. This work presents results of a combined approach using seismic interpretation and structural, isostatic and thermal modelling highlighting the structure of the crust. The seismic interpretation shows two rift-related discordances: one intra syn-rift and the break-up unconformity. The overlying sediments of the sag phase are less deformed (no sedimentary wedges) and accumulated before the generation of oceanic crust. The axis of the Colorado Basin trends E-W in the western part, where the deepest pre-rift series are preserved. In contrast, the basin axis turns to a NW-SE direction in its eastern part, where mainly post-rift sediments accumulated. The most distal part reaches the margin slope and opens into the oceanic basin. The general basin direction is almost orthogonal to the present-day margin trend. The most frequent hypothesis explaining this geometry is that the Colorado Basin is an aborted rift resulting from a previous RRR triple junction [e.g. Franke et al., 2002]. The structural interpretation

Crustal Stretching Style and Lower Crust Flow of the South China Sea Northern Margin

Science.gov (United States)

Bai, Y.; Dong, D.; Runlin, D.

2017-12-01

There is a controversy about crustal stretching style of the South China Sea (SCS) northern margin mainly due to considerable uncertainty of stretching factor estimation, for example, as much as 40% of upper crust extension (Walsh et al., 1991) would be lost by seismic profiles due to poor resolution. To discover and understand crustal stretching style and lower crustal flow on the whole, we map the Moho and Conrad geometries based on gravity inversion constrained by deep seismic profiles, then according to the assumption of upper and lower crust initial thickness, upper and lower crust stretching factors are estimated. According to the comparison between upper and lower crust stretching factors, the SCS northern margin could be segmented into three parts, (1) sediment basins where upper crust is stretched more than lower crust, (2) COT regions where lower crust is stretched more than upper crust, (3) other regions where the two layers have similar stretching factors. Stretching factor map shows that lower crust flow happened in both of COT and sediment basin regions where upper crust decouples with lower crust due to high temperature. Pressure contrast by sediment loading in basins and erosion in sediment-source regions will lead to lower crust flow away from sediment sink to source. Decoupled and fractured upper crust is stretched further by sediment loading and the following compensation would result in relatively thick lower crust than upper crust. In COT regions with thin sediment coverage, low-viscosity lower crust is easier to thin in extensional environment, also the lower crust tends to flow away induced by magma upwelling. Therefore, continental crust on the margin is not stretching in a constant way but varies with the tectonic setting changes.

Ocean-Continent Transition Structure of the Pelotas Magma-Rich Continental Margin, South Atlantic

2017-04-01

Rifted continental margins in the southern South Atlantic are magma-rich showing well developed volcanic extrusives known as seaward dipping reflectors (SDRs). Here we examine the magma-rich continental rifted margin of the Pelotas Basin, offshore Brazil. Deep seismic reflection data displays a large package of seaward dipping reflectors with an approximate width of 200 km and a varying thickness of 10 km to 17 km that have previously been interpreted as volcanic SDRs. We examine these SDRs to explore if they are composed predominantly of basaltic or sedimentary-volcaniclastic material. We also study the thickness of the crustal basement beneath the SDRs. Additionally we investigate if these SDRs are underlain by thin 'hyper-extended' continental crust or if they have been deposited on new magmatic basement. The answers to these questions are important in understanding the structure and formation processes of magma-rich continental margins. We use gravity inversion to investigate SDR composition by varying the proportion of basalt to sediments-volcaniclastics (basalt fraction) which determines the SDR densities in the gravity inversion. By matching the Moho depth and two-way travel time from gravity inversion and deep seismic reflection data, we determine the lateral variation in basalt fraction of the SDRs. Our analysis suggests: 1) There is an overall pattern of SDR basalt fraction and bulk density decreasing oceanward. This could be due to increasing sediment content oceanward or it could result from the change in basalt flows to hyaloclastites as water depth increases. 2) The SDR package can be split into two distinct sub packages based on the basalt fraction results, where the proximal side of each package has a higher basalt fraction and density. 3) The inner SDR package contains reflectors that bear a resemblance to the SDRs described by Hinz (1981) corresponding to syn-tectonic volcanic eruptions into an extensional basin, while the outer SDR package has

2015-01-01

Purpose Functional impairment is a key indicator of need for mental health services among children and adolescents, often a stronger predictor of service usage than mental health symptoms themselves. Functional impairment may be of particular importance in low and middle income countries (LMIC) because of its potential to focus policy on treatment of child mental health problems which is generally given low priority in LMIC. However, few studies have assessed functional impairment in LMIC. The present study assessed rates of functional impairment among children in Vietnam, as a case example of an LMIC, as well as effects of other risk/protective factors of particular relevance to LMIC (e.g., whether the family lived in an urban or rural area; family structure variables such as grandparents living with the family). Methods 1,314 parents of children 6–16 years old from 10 Vietnamese provinces were interviewed. Results The overall rate of functional impairment among Vietnamese children was 20%, similar to rates in high income countries such as Germany and the United States, suggesting that LMIC status may not be associated with dramatic increases in functional impairment in children. Functional impairment was significantly greater among mental health cases than non-cases, with increases of over 550% associated with mental health caseness. A number of other risk factors (e.g., marital status) had smaller but significant effects. Conclusions Mental health problems are a major but not the sole contributor to functional impairment among Vietnamese children. The pragmatic significance of this research lies in its potential to affect public awareness and policy related to child mental health in LMIC. PMID:26315942

This paper explores how a group of Vietnamese Australian young women acquire knowledge of sexual issues, and the impact the traditional Vietnamese culture has on the acquisition of this knowledge. It is based on a qualitative study that examined the factors which shape the sexual behaviour of Vietnamese Australian young women living in Australia. A Grounded Theory methodology was employed in this investigation, and involved in-depth interviews with 15 Vietnamese Australian young women aged 18-25 years, who reside in Victoria, Australia. The findings illustrated three key elements involved in the acquisition of knowledge of sexual issues: 'Accepting parental silence', 'Exploring sources of knowledge' and 'Needing culturally targeted information'. The young women desired discussion about sexual issues but accepted that cultural 'barriers' were formidable. Their desire conflicted with the traditional familial norm of 'silence' regarding sexual matters. Consequently, knowledge was sought outside the home, specifically from peers and the media. The importance of culturally appropriate and adequate sexual discussions for Vietnamese Australian young people was stressed, so that informed decisions could be made about their sexual lives. It is imperative for young people to have adequate and appropriate sexual education so that informed and safe sexual choices can be made. For young people from diverse cultural backgrounds, this education must be culturally appropriate and accessible, taking into consideration cultural mores regarding gender and sexual matters, as well as current beliefs in the 'mainstream' youth culture.

Early Jurassic Volcanism in the South Lhasa Terrane, Southern Tibet: Record of Back-arc Extension in the Active Continental Margin

2015-12-01

Indus-Yarlung Zangbo Suture Zone (IYZSZ) represents the Mesozoic remnants of the Neo-Tethyan Ocean lithosphere after its northward subduction beneath the Lhasa Terrane. The evolution of the Neo-Tethyan Ocean prior to India-Asia collision remains unclear. To explore this period of history, we investigate zircon U-Pb geochronology, geochemistry and Nd-Hf isotopes of the Early Jurassic bimodal-like volcanic sequence around Dagze area, south Tibet. The volcanic sequence comprises calc-alkaline basalts to rhyolites whereas intermediate components are volumetrically restricted. Zircons from a basaltic andesite yielded crystallization age of 178Ma whereas those from 5 silicic rocks were dated at 183-174Ma, which suggest that both the basaltic and the silicic rocks are coeval. The basaltic rocks are enriched in LREE and LILE, and depleted in HFSE, with Epsilon Nd(t) of 1.6-4.0 and zircon Epsilon Hf(t) of 0.7-11.8, which implies that they were derived from a heterogenetic mantle source metasomatized by subduction components. Trace element geochemistry shows that the basaltic rocks are compositionally transitional from normal mid-ocean ridge basalts (N-MORB) to island arc basalts (IAB, e.g. Zedong arc basalts of ~160-155Ma in the south margin of Lhasa Terrane), with the signature of immature back-arc basin basalts. The silicic rocks display similar Nd-Hf isotopic features of the Gangdese batholith with Epsilon Nd(t) of 0.9-3.4 and zircon Epsilon Hf(t) of 2.4-17.7, indicating that they were possibly generated by anatexis of basaltic juvenile lower crust, instead of derived from the basaltic magma. These results support an Early to Middle Jurassic (183-155Ma) model that the back-arc extension tectonic setting were existing in the active continental margin in the south Lhasa Terrane.

Nguyen, Hung M; Cihlar, Volker

2013-06-01

This cross-sectional study aims to investigate the differences in physical fitness and subjectively rated physical health of Vietnamese and German older adults in a community dwelling. The Vietnamese sample was a random sample of 96 community-dwelling individuals aged 60 to 80 years; 50 % were women. Education is 0 % less than 5 years, 23.95 % 5 to 9 years, 47.91 % 10 to 12 years, and 28.12 % more than 12 years. The German sample was a random sample of 159 community-dwelling persons aged 59 to 90 years; 79.8 % were women. Education is 1.25 % less than 5 years, 40.25 % 5 to 9 years, 38.84 % 10 to 12 years, and 21.38 % more than 12 years. Senior Fitness Test and Short Form-36 were used as outcome measures. The Vietnamese sample shows significantly higher performance levels in motor abilities, i.e., aerobic fitness, strength, and flexibility. The Vietnamese sample indicates a lower difference in performance levels between age groups than the German sample. No differences in subjectively rated physical health factors were found. The higher performance levels of the Vietnamese sample might reflect a more active lifestyle throughout the life span, especially in socially mediated domains like living arrangements or labor work. Lower performance levels in the studied age groups of the German sample might lead to higher risks of cardiovascular diseases and proneness of falls. A more active lifestyle after retirement could contribute to a healthier, more capable, and more independent individual and collective aging. Subjectively rated health stated is a culturally mitigated domain and therefore might be independent of actual physical fitness levels.

We develop a theory of trading middlemen or entrepreneurs who perform financing, quality supervision and marketing roles for goods produced by suppliers or workers. Brand-name reputations are necessary to overcome product quality moral hazard problems; middlemen margins represent reputational incentive rents. We develop a two sector North-South model of competitive equilibrium, with endogenous sorting of agents with heterogenous entrepreneurial abilities into sectors and occupations. The Sout...

2002-01-01

Coral bleaching, involving the expulsion of symbiotic zooxanthellae from the host cells, poses a major threat to coral reefs throughout their distributional range. The role of temperature in coral bleaching has been extensively investigated and is widely accepted. A bleaching event was observed on the marginal high-latitude reefs of South Africa located at Sodwana Bay during the summer months of 2000. This was associated with increased sea temperatures with high seasonal peaks in summer and increased radiation in exceptionally clear water. The bleaching was limited to Two-mile Reef and Nine-mile Reef at Sodwana Bay and affected -1 from May 1994 to April 2000. High maximum temperatures were measured (>29 deg. C). The lowest mean monthly and the mean maximum monthly temperatures at which coral bleaching occurred were 27.5 and 28.8 deg. C, respectively, while the duration for which high temperatures occurred in 2000 was 67 days at ≥27.5 deg. C (4 days at ≥28.8 deg. C). Increased water clarity and radiation appeared to be a synergistic cause in the coral bleaching encountered at Sodwana Bay

Permian-Triassic Tethyan realm reorganization: Implications for the outward Pangea margin

2018-01-01

We present a new conceptual model to explain the first order Permian-Triassic evolution of the whole > 30 000 km long Pangea margin facing the Panthalassa ocean. Compilation of available geological, geochemical, geochronogical and paleomagnetic data all along this system allowed us to distinguish three part of the margin: western Laurentia, western Gondwana and eastern Gondwana. These segments record distinct tectonic and magmatic events, which all occur synchronously along the whole margin and correlate well with the main geodynamic events of this period, i.e. subduction of the Paleotethys mid-ocean ridge at 310-280 Ma, opening of the Neotethys at 280-260 Ma, counterclockwise rotation of Pangea at 260-230 Ma and closure of the Paleotethys at 230-220 Ma. Between 260 and 230 Ma, the reorganization of the Tethyan realm triggered the up to 35° rotation of Pangea around an Euler pole located in northernmost South America. This implied both an increase and a decrease of the convergence rate between the margin and the Panthalassa ocean, north and south of the Euler pole, respectively. Thus, the Permian-Triassic Pangean margin was marked: in western Laurentia by marginal sea closure, in western Gondwana by widespread bimodal magmatic and volcanic activity, in eastern Gondwana by transpressive orogenic phase. Therefore, we propose that the Permian-Triassic evolution of the outward margin of Pangea was controlled by the Tethyan realm reorganization.

Nguyen, Uyen N; Rowe, Dorothy J; Barker, Judith C

2017-04-01

Purpose: The purpose of this study was to investigate the oral health knowledge, beliefs, and behaviors of migrant Vietnamese parents of 1-5 year-olds in San Jose, California. Method: A verbally-administered survey was conducted with a convenience sample of 45 Vietnamese parents recruited at San Jose public libraries. Following preliminary screening, written informed consent was obtained from eligible individuals. A pre-tested, structured 94-item questionnaire was used to collect information regarding parent demographics, and the parent's knowledge, beliefs, and behaviors about children's oral health. Simple descriptive statistics were used to analyze the data. Results: Vietnamese parents acknowledged a number of basic concepts regarding early childhood caries (ECC), such as influences of sugar consumption, oral hygiene, and bottle use. Unlike other groups, they reported some familiarity with the role of bacteria in caries etiology. Oral health knowledge and beliefs, however, were not reflected in parental oral health behaviors such as supervision of children's brushing. Knowledge about the preventive role of fluoride was limited and varied among the population. Parental knowledge and behaviors did not vary by education level or length of residence in US. Conclusion: Vietnamese parents demonstrated reasonably good oral health knowledge, but poor behavioral guidance of their children's oral health, indicating the need for continued parental education emphasizing age-appropriate oral care and the preventative role of fluoride.

2014-01-01

The aim of this study was to examine the influence of demographic variables and the interplay between gender roles and acculturation on breast and cervical cancer screening outcomes among Vietnamese American women. Convenience sampling was used to recruit 100 Vietnamese women from the Richmond, VA, metropolitan area. Women were recruited to participate in a larger cancer screening intervention. All participants completed measures on demographic variables, gender roles, acculturation, and cancer screening variables. Findings indicated that traditional masculine gender roles were associated with increased self-efficacy for breast and cervical cancer screening. Higher levels of acculturation were associated with higher probability of having had a Papanicolaou test. In addition, acculturation moderated the relationship between traditional female gender roles and cancer screening variables. For highly acculturated women, higher levels of feminine gender roles predicted higher probability of having had a previous clinical breast exam and higher levels of self-efficacy for cervical cancer screening, while the opposite was true for lower acculturated women. The findings of this study indicate the important roles that sociodemographic variables, gender roles, and acculturation play in affecting health attitudes and behaviors among Vietnamese women. These findings also help to identify a potentially high-risk subgroup and existing gaps that need to be targeted by preventive interventions.

Patients have to acquire information to support their decision on choosing a suitable healthcare provider. But in developing countries like Vietnam, accessibility issues remain an obstacle, thus adversely affect both quality and costliness of healthcare information. Vietnamese use both sources from health professionals and friends/relatives, especially when quality of the Internet-based cheaper sources appear to be still questionable. The search of information from both professionals and friends/relatives incurs some cost, which can be viewed as low or high depending low or high accessibility to the sources. These views potentially affect their choices. To investigate the effects that medical/health services information on perceived expensiveness of patients' labor costs. Two related objectives are a) establishing empirical relations between accessibility to sources and expensiveness; and, b) probabilistic trends of probabilities for perceived expensiveness. There is evidence for established relations among the variables "Convexp" and "Convrel" (all p's perceived expensiveness. a) Probabilistic trends show Vietnamese patients have propensity to value healthcare information highly and do not see it as "expensive"; b) The majority of Vietnamese households still take non-professional advices at their own risks; c) There is more for the public healthcare information system to do to reduce costliness and risk of information. The Internet-based health service users communities cannot replace this system.

Vietnamese-Australian grandparenthood: the changing roles and psychological well-being.

Vo-Thanh-Xuan, J; Rice, P L

2000-01-01

This study attempts to understand the Vietnamese-Australian grandparenthood and their changing roles and psychological well-being. Using a qualitative approach, thirty-six grandparents participated in four focus group interviews. The findings reveal that Vietnamese grandparents play many important roles such as those of living ancestor, family historian, role model, teacher, mentor, nurturer, crony and mediator although at a reasonably modest level. Through assisting the parents, it creates a vital bridge between grandparents and grandchildren. Grandparents' most important roles are the maintenance of good emotional relationships and support, and the construction of harmony and continuity in their modified extended families. To be able to assume these roles grandparents need to actively explore and accept new values and to adapt values to new cultural context. A successful grandparenthood brings happiness to the family and this in turn positively influences grandparents' life satisfaction and psychological well-being and enhances their quality of life.

Religious and Spiritual Dimensions of the Vietnamese Dementia Caregiving Experience

Hinton, Ladson; Tran, Jane NhaUyen; Tran, Cindy; Hinton, Devon

2010-01-01

This paper focuses on the role of religion and spirituality in dementia caregiving among Vietnamese refugee families. In-depth qualitative interviews were conducted with nine Vietnamese caregivers of persons with dementia, then tape-recorded, transcribed, and analyzed for emergent themes. Caregivers related their spirituality/religion to three aspects of caregiving: (1) their own suffering, (2) their motivations for providing care, and (3) their understanding of the nature of the illness. Key terms or idioms were used to articulate spiritual/religious dimensions of the caregivers’ experience, which included sacrifice, compassion, karma, blessings, grace and peace of mind. In their narratives, the caregivers often combined multiple strands of different religions and/or spiritualities: Animism, Buddhism, Taoism, Confucianism and Catholicism. Case studies are presented to illustrate the relationship between religion/spirituality and the domains of caregiving. These findings have relevance for psychotherapeutic interventions with ethnically diverse populations. PMID:20930949

2017-09-01

The implementation of social constructivist approaches to learning science in primary education in Vietnamese culture as an example of Confucian heritage culture remains challenging and problematic. This theoretical paper focuses on the initial phase of a design-based research approach; that is, the description of the design of a formal, written curriculum for primary science education in which features of social constructivist approaches to learning are synthesized with essential aspects of Vietnamese culture. The written design comprises learning aims, a framework that is the synthesis of learning functions, learning settings and educational expectations for learning phases, and exemplary curriculum units. Learning aims are formulated to comprehensively develop scientific knowledge, skills, and attitudes toward science for primary students. Derived from these learning aims, the designed framework consists of four learning phases respectively labeled as Engagement, Experience, Exchange, and Follow-up. The designed framework refers to knowledge of the "nature of science" education and characteristics of Vietnamese culture as an example of Confucian heritage culture. The curriculum design aims to serve as an educational product that addresses previously analyzed problems of primary science education in the Vietnamese culture in a globalizing world.

Indigenous resources of the Asian pig population are less defined and only rarely compared with European breeds. In this study, five indigenous pig breeds from Viet Nam (Mong Cai, Muong Khuong, Co, Meo, Tap Na), two exotic breeds kept in Viet Nam (Large White, Landrace), three European commercial breeds (Pietrain, Landrace, Large White), and European Wild Boar were chosen for evaluation and comparison of genetic diversity. Samples and data from 317 animals were collected and ten polymorphic microsatellite loci were selected according to the recommendations of the FAO Domestic Animal Diversity Information System (DAD-IS; http://www.fao.org/dad-is/). Effective number of alleles, Polymorphism Information Content (PIC), within-breed diversity, estimated heterozygosities and tests for Hardy-Weinberg equilibrium were determined. Breed differentiation was evaluated using the fixation indices of Wright (1951). Genetic distances between breeds were estimated according to Nei (1972) and used for the construction of UPGMA dendrograms which were evaluated by bootstrapping. Heterozygosity was higher in indigenous Vietnamese breeds than in the other breeds. The Vietnamese indigenous breeds also showed higher genetic diversity than the European breeds and all genetic distances had a strong bootstrap support. The European commercial breeds, in contrast, were closely related and bootstrapping values for genetic distances among them were below 60%. European Wild Boar displayed closer relation with commercial breeds of European origin than with the native breeds from Viet Nam. This study is one of the first to contribute to a genetic characterization of autochthonous Vietnamese pig breeds and it clearly demonstrates that these breeds harbour a rich reservoir of genetic diversity.

2013-04-01

Full Text Available After the fall of the Berlin Wall and the breakdown of the East German Socialistgovernment, thousands of former contract workers from Vietnam stayedin the then reunified Germany. Due to their resulting precarious economicsituation, a large number of these migrants became engaged in small businessand petty trade. Some of them, women in particular, have become successfulentrepreneurs and wholesalers in recently built bazaars in the eastern parts ofBerlin. Most interestingly, parts of these urban spaces, former industrial areason the periphery of Germany’s capital, have been transformed into religiousplaces. This article explores the formation of female Vietnamese Buddhistnetworks on the grounds of Asian wholesale markets. It argues that transnationalmobilities in a post-socialist setting encourage border-crossing religious activities,linking people and places to various former socialist countries as well as to theSocialist Republic of Vietnam. Further, by considering political tensions betweenVietnamese in the eastern and western part of Berlin, this contribution illustratesthe negotiation of political sensitivities among diasporic Vietnamese in reunitedGermany. Based on ethnographic fieldwork among female lay Buddhists, itfocuses on entrepreneurship and investigates the relationship between business,migration and religious practices.

Vietnam and the South China Sea: Politics, Security and Legality. New York: Routledge, 2017. The two books under review here demonstrate some of the diversity of writing within the discipline of international relations. In China’s Troubled Waters: Maritime Disputes in Theoretical Perspectives, political scientist Steve Chan, following Kant, describes his style as “nomothetic,” “which emphasizes attention to classes of events rather than specific episodes” (vii. Strategic and defense studies scholar Do Thanh Hai’s Vietnam and the South China Sea: Politics, Security and Legality is an example of what Chan calls the “idiographic approach,” focusing “on the more unique or specific aspects of the situation” (vii. Chan wants to be able to generalize and compare, and he explicitly eschews narratives of “who did what to whom.” Hai, on the other hand, is keen to make clear that it is China who did something to Vietnam. The most obvious criticism to make of his book is that it is written from an overtly Vietnamese perspective. That is a weakness, but also potentially a draw for those interested in the formulation of Vietnamese policy. Chan writes from an ostensibly neutral position, but, as we shall see, his analysis is rooted within a Chinese world view.

White, Lesley; Klinner, Christiane

2012-01-01

There is a paucity of research into the perceptions of elderly Australian ethnic minorities towards public health services related to quality use of medicines. Among the six fastest growing ethnic groups in Australia, the Mandarin-speaking Chinese and Vietnamese constitute the largest elderly populations with poor English skills. This paper investigates the relationships of elderly Chinese and Vietnamese migrants with medicines, general practitioners and pharmacists, and how these relationships influence their awareness and attitudes of the home medicines review (HMR) program. Two semi-structured focus groups were held with a total of 17 HMR-eligible patients who have never received a HMR, one with Chinese and one with Vietnamese respondents, each in the respective community language. Confusion about medications and an intention to have a HMR were pronounced among all participants although none of them had heard of the program before participating in the focus groups. Respondents reported difficulties locating a pharmacist who spoke their native language, which contributed to an increased unmet need for medicine information. The Chinese group additionally complained about a lack of support from their general practitioners in relation to their medicine concerns and was adamant that they would prefer to have a HMR without the involvement of their general practitioner. Our results indicate a distinct HMR need but not use among elderly Chinese and Vietnamese eligible patients with poor English skills. Home medicines review service use and perceived medication problems are likely to improve with an increasing availability of bilingual and culturally sensitive health care providers.

The unzipping of Africa and South America; New insights from the Etendeka and younger volcanic events along the Angola/Namibia margin.

Jerram, D. A.

2015-12-01

The volcanic margin along Angola is relatively poorly constrained. This study uses new petrographic, geochronological and geochemical observations on a new sample set collected along the margin to help understand the various types and relative timings of volcanic events along the margin. This new study has identified 3 main volcanic events that occur at ~100Ma (Sumbe event 1), 90-92Ma (Serra de Neve (SDN)-Elefantes event 2) and 80-81Ma (Namibe event 3), with the oldest event in the north of the margin and younging southwards. This is contrasting with the main Etendeka pulse in Namibia at around 130 Ma. There is a marked variety of igneous rocks along the margin with a grouping of evolved alkaline rocks in the central SDN-Elefantes section, basic submarine volcanics in the north, and basanite eruptions in the southern section. There is some overlap with geochemical types along the margin. The Sumbe event contains predominantly submarine volcanics and shallow Intrusions. SDN-Elefantes rocks have a mixed type but with a distinctive feldspar rich evolved alkali suite of rocks (nepheline syenites and variations around this composition) which occur as lava flows and shallow intrusions as well as making up the core of the SDN complex. The SDN complex itself is analogous in size to the main volcanic centres in Namibia (such as Messum, Brandberg etc.) and suggests that large volcanic feeding centres are still active along the margin as young as 90ma. These in turn will form large volcano-topographic features. In the south the Ponta Negra and Canico sites mainly contain basanites in the form of lava flows, invasive flows and shallow intrusions. At Canico one intrusive plug was sampled with a similar composition to the evolved SDN-Elefantes suite. In all three events it is clear that the volcanic systems have interacted with the sedimentary systems, in some cases dynamically, in others with regional implications for volcano-tectonic uplift. Specific thanks is given for

Previous literature has suggested high rates of HIV/STIs among Chinese FSWs. However, limited data were available regarding HIV-related risks among Vietnamese FSWs - a rapidly increasing, vulnerable population in southwest China. The current study examined the demographic and behavioral factors associated with the infection rates of HIV, syphilis, and Hepatitis C (HCV) among Vietnamese FSWs in Guangxi, China. We conducted a secondary data analysis of a cumulative sample of 1026 Vietnamese FSWs (aged 14-66) recruited over five years (2010-2014) from 35 National Sentinel Surveillance sites in Guangxi. Analyses included Fisher's exact chi-square test, t-test, and binary logistic regression. The overall prevalence of HIV, syphilis, and HCV infections among the cross-border women were 3.2%, 6.9%, and 2.6%, respectively. Multivariate analysis showed that greater lengths of sex work and low paying work venues were significant risk factors for HIV infection; for syphilis infection, older age, drug use experience, and forgoing condom use were significant risk factors; for HCV infection, drug use experience was the only significant risk factor. Our findings suggest that elevated HIV-related risks among the Vietnamese FSWs are closely related to their financial disadvantages and that drug use is a prominent risk factor for cross-border women in the sex trade. Furthermore, culturally tailored and linguistically accessible HIV prevention and intervention initiatives that target cross-border FSWs, with a close international collaboration between China and Vietnam, are urgently needed.

Book review: The Sympathizer. A Vietnamese spy novel and the attempt to de-americanize our view on the war

Schmitz, Britta

2018-03-01

Full Text Available 1975, the Vietnam War has just ended, but the cold war and the clash of ideologies are still going on. This would of course be the perfect background for some run-of-the-mill thriller written by a white American for a Western audience. And without knowing anything further, we might first think that The Sympathizer, which was recently translated into German and marketed as a “thriller” and “spy novel”, would be just one of those. However, things and people are all too often not what they seem to be – an adage which has never been more true than in this story. Far more than simply a thriller, it is also a political novel, a satirical story, refugee literature and a critique of modern mass media, all interspersed with discursive passages and spiced with literary references and aphorisms. Furthermore, the author is not a white American. The Sympathizer is the debut novel of Vietnamese-American Viet Thanh Nguyen, which won him the Pulitzer Prize in 2016 along with a great many other awards. Nguyen was born in Vietnam and grew up in the USA from where he experienced both cultures and had insight to both perspectives on the Vietnam War. He is a Professor of English and American Studies and Ethnicity primarily focused on “Americanization”, how the American perspective continues to dominate film, literature and pop culture. His book is a critique of this prevailing view and includes the issues of acculturation and identity crisis of immigrants, along with the importance of loyalty and relationships (or the lack of those. The narrator and protagonist of the story is a man who has no name and is only referred to as “the captain” throughout the book. We encounter him fleeing Saigon, accompanying a general of the South Vietnamese army, we know already that he has a secret. In the very first lines he reveals that he is a sleeper agent and actually working for the Viet Cong and spying on the South Vietnamese military and the CIA. The captain�

Full Text Available This study empirically examines relationship between FDI spill-overs and technical efficiency of domestic firms and role of the absorptive capacity of domestic firms. Data on Vietnamese Annual Enterprises Survey are exploited to build a firm-level panel data on the Vietnamese wearing apparel industry from 2009 to 2013. By applying stochastic production frontier model, this paper shows that there are positive vertical spill-over effects but no horizontal effects. Moreover, this study finds the negative impact of the absorptive capacity of domestic firms on benefits reaped from FDI externalities.

Mineral exploration drillholes and geoelectric prospecting provide for the first time evidence for thrusting of the South Carpathian Paleozoic basement over northerly adjacent Middle Miocene sediments. Investigations were carried out in two locations, 30 km apart, along the northern margin of the Poiana Rusca Mountains, Romania, southwestern Carpathians. Drill holes in both locations encountered weakly consolidated Middle Miocene clay, sand, and fine gravel below Paleozoic low-grade metamorphic rocks. Intersections from various drill holes demonstrate the presence of low-angle thrusting. Kinematic indicators are so far lacking, but with a thrust direction oriented roughly normal to strike of the Poiana Rusca Mountains, minimum displacement is 1-1.4 km in northwestern or northern direction, respectively. Thrusting occurred most likely during the Late Miocene-Pliocene, whereafter Quaternary regional uplift dissected the thrust plane. In the tectonic framework of Neogene dextral translation of the Tisza-Dacia Block against the southerly adjacent Moesian Platform, transtension appears responsible for Middle Miocene basin formation along the northern margin of the Poiana Rusca region. Proceeding collision of the Tisza-Dacia Block with the East European Craton introduced stronger impingement of the Tisza-Dacia Block against the Moesian Platform, leading to a Late Miocene-Pliocene transpressional regime, in which the northern Poiana Rusca basement was thrust over its adjacent Middle Miocene sediments.

Humans and other living organisms require small quantities of trace elements throughout life. Both insufficient and excessive intakes of trace elements can have negative consequences. However, there is little information on serum level of trace elements in different populations. This study examines serum levels of trace elements in Ethiopian, Japanese, and Vietnamese women. Random samples of healthy women who were referred for routine hospital laboratory examinations in the cities of Hanoi, Sapporo, and Gondar were invited to participate in the study. Serum levels of magnesium, zinc, copper, iron, selenium, and calcium were determined using an inductively coupled plasma mass spectrometer. Furthermore, body mass index of each study participant was determined. The mean ± SD serum concentrations of zinc (μg/dL), copper (μg/dL), iron (μg/dL), selenium (μg/dL) and calcium (mg/dL), respectively, were 76.51 ± 39.16, 152.20 ± 55.37, 385.68 ± 217.95, 9.15 ± 4.21, and 14.18 ± 3.91 in Ethiopian women; 111.49 ± 52.92, 105.86 ± 26.02, 155.09 ± 94.83, 14.11 ± 3.41, and 11.66 ± 2.51 in Vietnamese women; and 60.69 ± 9.76, 107 ± 156, 268 ± 128, 8.33 ± 3.65, and 11.18 ± 0.68 in Japanese participants. Ethiopian women had significantly higher level of serum calcium than Vietnamese and Japanese women (both P Vietnamese women was higher than in women from Japan, the difference was not statistically significant (P > 0.05). Furthermore, compared with Japanese women, Ethiopian women had significantly high iron and copper concentrations (P Vietnamese than Ethiopian women. The study revealed a remarkable difference in serum concentrations of trace elements in women from different countries, implying differences in trace elements in the food or soil.

Secondary school can be a stressful period for adolescents, having to cope with many life changes. Very little research has been conducted on the mental health status of secondary school pupils in South East Asian countries, such as Vietnam.The study aimed to explore perceptions of mental health status, risk factors for mental health problems and strategies to improve mental health among Vietnamese secondary school students. A qualitative design was used to address the main study question including: six in-depth interviews conducted with professionals (with two researchers, two psychiatrists, and two secondary school teachers) to learn about their experience of mental health problems among secondary school pupils; 13 focus group discussions (four with teachers, four with parents, and five with pupils); and 10 individual in-depth interviews with pupils who did not take part in the FGDs, to reflect on the collected data and to deepen the authors' understanding. All interviews and FGDs were audio-taped, transcribed and analyzed for the identification of emerging issues using qualitative techniques of progressive coding, analytic memoing and ongoing comparison. Our study confirms the need to pay attention to mental health of pupils in Vietnam. Depression, anxiety, stress, suicidal thoughts and suicide attempts were seen as major problems by all stakeholders. Mental health problems were mainly associated with academic pressure, resulting from an overloaded curriculum and pressure from teachers and parents to succeed. The study found that pupils' mental health demands interventions at many levels, including at the level of government (Ministry of Education and Training), schools, communities, families and pupils themselves. Vietnamese secondary school pupils feel that their mental health status is poor, because of many risk factors in their learning and living environment. The need now is to investigate further to identify and apply strategies to improve students' mental

Geodynamical models have been widely used to explain the variability in the architectonical style of conjugate rifted margins as a combination of lithospheric deformation modes, which are strongly influenced by lower crustal strength. We use 2D numerical models to show that the lower crustal strength also plays a key role on the onset and amount of melting and serpentinization during continental rifting. The relative timing between melting and serpentinization onsets controls whether the continent-ocean transition (COT) of margins will be predominantly magmatic or will mainly consist of exhumed and serpentinized mantle. Based on our results for magma-poor continental rifting, we propose a genetic link between margin architecture and COT styles that can be used as an additional tool to help interpret and understand the processes leading to margin formation. Our results show that strong lower crusts and very slow extension velocities (architecture of the magma-poor section of the South Atlantic, we suggest that the COT of the northern sector, Camamu-Gabon basins, is more likely to consist of exhumed mantle with intruded magmatism, while to the South, the Camamu-Kwanza and North Santos-South Kwanza conjugates, may be better characterized by a predominantly magmatic COT.

Influence of margin segmentation and anomalous volcanism upon the break-up of the Hatton Bank rifted margin, west of the UK

The Hatton Bank margin, flanking the Iceland Basin is a widely cited example of a volcanic rifted margin. Prior to this study insights into the break-up history of the margin have been limited to profiles in the north and south, yet whilst valuable, the along margin tectono-magmatic variability has not been revealed. Over 5660 line km of high quality reflection seismic profiles with supplementary multibeam bathymetry were collected to support the UK's claim to Hatton region under the United Nations Convention on Law of the Sea (UNCLOS). Integration of this new data with existing profiles, allowed the margin to be divided into three segments, each of which are flanked by oceanic crust with a smooth upper surface and internal dipping reflectors. The southernmost segment is characterised by a series of inner and outer seaward dipping reflector (SDR) packages, which are separated by an outer high feature. The outer SDR are truncated by Endymion Spur, a chain of steep sided, late stage volcanic cones linked with necks. The central sector has no inner SDR package and is characterised by the presence of a highly intruded continental block, the Hatton Bank Block (HBB). The northern sector is adjacent to Lousy Bank, with a wider region of SDR recognised than to the south and a high amount of volcanic cones imaged. The variations in the distribution of the SDR's along the margin, the presence of the HBB and Endymion Spur all suggest that the break-up process was not uniform alongstrike. The division of the margin into three sectors reveals that structural segmentation played an important role in producing the variations along the margin. Break- up initiated in the south and progressed north producing the SDR packages witnessed, when the HBB was encountered the focus of break-up moved seaward of the block. The northern sector was closer to the Iceland Hotspot and hence a greater amount of volcanism is encountered. The smooth oceanic basement also indicates a high thermal flux

Primary congenital glaucoma (PCG, OMIM 231300), the most common glaucoma in infancy, is caused by developmental defects in the anterior chamber angle. The 3 implicated genes are cytochrome P450 family I subfamily B polypeptide 1 (CYP1B1), latent transforming growth factor β-binding protein 2 (LTBP2), and myocilin (MYOC). In this study, we sought to determine CYP1B1 and MYOC sequence variations in a Vietnamese cohort of index cases with PCG and their families. Thirty Vietnamese subjects with PCG and 120 normal Vietnamese subjects were recruited. PCG was defined by the presence of at least 2 of the following clinical manifestations: increased corneal diameter (>10 mm at birth), corneal edema, Haab's striae, optic disc changes, and absence of other ocular or systemic diseases associated with childhood glaucoma. The coding exons, intron and exon boundaries, and untranslated regions of CYP1B1 and MYOC genes were PCR amplified and subjected to bidirectional sequencing in all subjects. We identified 2 homozygous and 3 heterozygous CYP1B1 sequence alterations in our study subjects. Among the 5 mutations identified, 2 (p.H279L and p.L283F) were novel mutations, whereas 3 (p.A121_S122insDRPAFA, p.L107V, and p.V320L) had been previously reported in PCG cases. None of these mutations was observed in any of the 120 controls. Haplotypes generated with 6 non-disease-causing intragenic single nucleotide polymorphisms detected in CYP1B1 indicated that the most common haplotype in Vietnamese population is similar to that found in Chinese and Japanese. The genotype-phenotype correlation showed no significant difference between mutation and no-mutation groups for quantitative clinical features (presenting intraocular pressure, corneal diameter, number of surgeries performed, the cup-to-disc ratio) as well as for qualitative factors (bilateral cases, phenotype severity, and the prognosis) (P>0.05). Five out of 30 families with PCG (16.7%) had disease attributable to CYP1B1 alterations

To evaluate the effectiveness of a community-based liver cancer prevention program on hepatitis B virus (HBV) screening among low-income, underserved Vietnamese Americans at high risk. We conducted a cluster randomized trial involving 36 Vietnamese community-based organizations and 2337 participants in Pennsylvania, New Jersey, and New York City between 2009 and 2014. We randomly assigned 18 community-based organizations to a community-based multilevel HBV screening intervention (n = 1131). We randomly assigned the remaining 18 community-based organizations to a general cancer education program (n = 1206), which included information about HBV-related liver cancer prevention. We assessed HBV screening rates at 6-month follow-up. Intervention participants were significantly more likely to have undergone HBV screening (88.1%) than were control group participants (4.6%). In a Cochran-Mantel-Haenszel analysis, the intervention effect on screening outcomes remained statistically significant after adjustment for demographic and health care access variables, including income, having health insurance, having a regular health provider, and English proficiency. A community-based, culturally appropriate, multilevel HBV screening intervention effectively increases screening rates in a high-risk, hard-to-reach Vietnamese American population.

Despite an extensive body of research on somatic symptom presentation among people of East- and Southeast-Asian descent, results are still inconclusive. Examining and comparing symptom presentation in clinically and ethnically well-characterized populations may constitute a step towards understanding symptom presentation between patients with a different cultural background. This study aims to compare Vietnamese and German patients regarding cultural dynamics of symptom presentation upon first admission to a psychiatric outpatient service. 110 Vietnamese and 109 German patients seeking psychiatric treatment at two outpatient clinics completed the Patient Health Questionnaire (PHQ). The somatic symptom subscale (PHQ-15), the depression subscale (PHQ-9) and PHQ-subscales examining anxiety and psychosocial stress levels were analyzed and compared for both groups using multivariate analysis of covariance. Regression analysis was utilized to examine the influences of sociodemographic and migration specific factors. Vietnamese and German patients showed comparable Cronbach's alpha for all subscales. Vietnamese patients endorsed significantly higher levels of somatic symptoms overall and on certain items (as pain-related items, dizziness, and fainting spells) despite similar levels of depression severity in comparison with German patients. Vietnamese patients with poor German language skills showed a significantly higher focus on somatic symptoms. Raising awareness for cultural dynamics of symptom presentation in patients with depression is indispensable. Cross-cultural symptom assessment using the PHQ seems feasible and expands our understanding of depressive and psychosomatic symptoms when assessed by clinicians. Copyright © 2017.

The Vietnamese lending rate, policy-related rate, and monetary policy post-1997 Asian financial crisis

Directory of Open Access Journals (Sweden)

Chu V. Nguyen

2015-12-01

Full Text Available Asymmetries in the Vietnamese lending central bank’s policy-related rate spread were documented. Empirical results revealed that the spread adjusts to the threshold faster when the central bank’s policy-related rates decrease relative to the lending rates than when the central bank’s policy-related rates move in the opposite direction. Additionally, the empirical findings indicate that Vietnamese commercial banks exhibit competitive rate setting behavior which may be attributable to graft maximization by bank’s management. The results also show bidirectional Granger causality between the Vietnamese lending rate and the central bank’s policy-related rate, indicating that the lending rate and the central bank’s policy-related rate affect each other’s movements. These results suggest that monetary authority can use its countercyclical monetary policy instruments to achieve its macroeconomics objectives. However, the estimation results of the GARCH (2, 3-in-Mean model suggest that they should intervene more frequently and by small policy measures to minimize the conditional variance of the spread to minimize the magnitude of the cycle of the lending rate.

This paper presents new results obtained from investigating the data from a 2015 Vietnamese entrepreneurs' survey, containing 3071 observations. Evidence from the estimations using multinomial logits was found to support relationships between several sociocultural factors and entrepreneurship-related performance or traits. Specifically, those relationships include: (a) Active participation in entrepreneurs' social networks and reported value of creativity; (b) CSR-willingness and reported entrepreneurs' perseverance; (c) Transforming of sociocultural values and entrepreneurs' decisiveness; and, (d) Lessons learned from others' failures and perceived chance of success. Using geographical locations as the control variate, evaluations of the baseline-category logits models indicate their varying effects on the outcomes when combined with the sociocultural factors that are found to be statistically significant. Empirical probabilities that give further detail about behavioral patterns are provided; and toward the end, the paper offers some conclusions with some striking insights and useful explanations on the Vietnamese entrepreneurship processes.

Lithospheric thickness jumps at the S-Atlantic continental margins from satellite gravity data and modelled isostatic anomalies

Science.gov (United States)

Shahraki, Meysam; Schmeling, Harro; Haas, Peter

2018-01-01

Isostatic equilibrium is a good approximation for passive continental margins. In these regions, geoid anomalies are proportional to the local dipole moment of density-depth distributions, which can be used to constrain the amount of oceanic to continental lithospheric thickening (lithospheric jumps). We consider a five- or three-layer 1D model for the oceanic and continental lithosphere, respectively, composed of water, a sediment layer (both for the oceanic case), the crust, the mantle lithosphere and the asthenosphere. The mantle lithosphere is defined by a mantle density, which is a function of temperature and composition, due to melt depletion. In addition, a depth-dependent sediment density associated with compaction and ocean floor variation is adopted. We analyzed satellite derived geoid data and, after filtering, extracted typical averaged profiles across the Western and Eastern passive margins of the South Atlantic. They show geoid jumps of 8.1 m and 7.0 m for the Argentinian and African sides, respectively. Together with topography data and an averaged crustal density at the conjugate margins these jumps are interpreted as isostatic geoid anomalies and yield best-fitting crustal and lithospheric thicknesses. In a grid search approach five parameters are systematically varied, namely the thicknesses of the sediment layer, the oceanic and continental crusts and the oceanic and the continental mantle lithosphere. The set of successful models reveals a clear asymmetry between the South Africa and Argentine lithospheres by 15 km. Preferred models predict a sediment layer at the Argentine margin of 3-6 km and at the South Africa margin of 1-2.5 km. Moreover, we derived a linear relationship between, oceanic lithosphere, sediment thickness and lithospheric jumps at the South Atlantic margins. It suggests that the continental lithospheres on the western and eastern South Atlantic are thicker by 45-70 and 60-80 km than the oceanic lithospheres, respectively.

The Creation of a Nonexistent Group: Sino-Vietnamese Couples in China’s Borderlands

Directory of Open Access Journals (Sweden)

Caroline Grillot

2015-06-01

Full Text Available Marriage migration to mainland China has only recently attracted attention in public and academic discourse. Driven by a complex combination of structural and personal factors, many of these marriages remain unregistered, and understanding them requires a different approach than that used to study other international marriages in the region. To date, most discussions have addressed the phenomenon from a legal, demographic, or economic perspective. Considered as illegal migrants, many of the foreign women involved in these marriages are reduced to silence. Based on the specific case of Vietnamese women engaged in de facto marriages with Chinese men in China’s southern borderlands, this article describes several factors affecting this social group: the condition of “nonexistence” that the couples experience in their daily lives; the local response to their presence in Chinese communities; and the ambivalent position of governmental bodies regarding their residence and life in China. This ground-level perspective demonstrates how the apparent tolerance of this complex phenomenon may, in the long term, actually create more disturbance in local communities than would be expected. This article reveals how significant gaps between official migration policies and actual practices of governance at the local level limit the social integration of marginalized individuals by sustaining the conditions for their long-term invisibility.

Objective of the current study was to evaluate proportions of frontal facial soft-tissues of Vietnamese females correspond to the golden proportion (GP). Sixty frontal facial photographs of Vietnamese female students aged 19 years were selected. The selected participants had symmetrical face, a Class I relationship occlusion, complete lip closure, and no history of trauma and orthodontic treatment. The photographic record was set-up with a white backdrop, fill light, a reflector, a camera Canon 650D and subjects were asked to sit in a standard position. Trichion (TR), Temporal soft tissue (TS), Lateral canthus (LC), Lateral nasal (LN), Chilion (CH), and Menton (ME) point were used for photometric measurements on CorelDRAW Graphic X3 software. The vertical facial proportions (mean, percentage compared with GP) were significantly higher than the GP including: LC-CH:CH-ME (1.661, 102%), LN-ME:LC-LN (1.729, 106%), TR-ME:LC-ME (1.739, 107%), TR-LN:LN-ME (1.759, 108%). Whereas TR-ME:LN-ME; CH-ME:LN-CH; LC-LN:LN-CH had ratios of 84% - 92% and were significantly smaller in comparison with GP. The horizontal facial proportions of CHR-L:LNR-L, LCR-L:CHR-L and TSR-L:LCR-L deviated from the GP with mean values of 1.221, 1.922 and 1.229, respectively. The new mean values of TR-ME:LC-ME (1.733), TR-LN:LN-ME (1.732), LC-ME:TR-LC (1.374), CH-ME:LN-CH (1.524), which were predictable changes in proportions, can be significantly converged to the GP if LC-CH:CH-ME is equal to the GP. Soft-tissue facial proportions of Vietnamese females did not correspond to the GP. Changing the lower third face may create harmony vertical facial proportions.

Low temperature thermochronology and topographic evolution of the South Atlantic passive continental margin in the region in eastern Argentina

To understand the evolution of the passive continental margin in Argentina low temperature thermochronology is an appropriate method, which will lead to new conclusions in this area. The Tandilia System, also called Sierras Septentrionales, is located south of the Río de la Plato Craton in eastern Argentina in the state of Buenos Aires. North of the hills Salado basin is located whereas the Claromecó basin is situated south of the mountain range. In contrary to most basins along the southamerican passive continental margin the Tandilia-System and the neighbouring basins trend perpendicular to the coast line. The topography is fairly flat with altitudes of. The igneous-metamorphic basement is pre-proterozoic in age and build up of mainly granitic-tonalitic gneisses, migmatites, amphibolites, some ultramafic rocks and granitoid plutons it is overlain by a series of Neoproterozoic to early Paleozoic sediments (Cingolani, 2010), like siliciclastics, dolostones, shales and limestones (Demoulin et al., 2005). The aim of the study is to quantify the long-term landscape evolution of the passive continental margin in eastern Argentina in terms of thermal history, exhumation and tectonic activities. For that purpose, samples were taken from the Sierra Septentrionales and analyzed with the apatite fission-track method. Further 2-D thermokinematic modeling was conducted with the computer code HeFTy (Ketcham, 2005; Ketcham 2007; Ketcham et al., 2009). The results indicate apatite fission track ages between 101.6 (9.4) to 228.9 (22.3) Ma, what means all measured ages are younger as their formation age. That shows all samples have been reset. Six samples accomplished enough confined tracks and were used to test geological t-T models against the AFT data set. These models give a more detailed insight on the cooling history and tectonic activities in the research area. References: Cingolani C. A.

Crustal Deformation In the Northwestern Margin of the South China Sea: Results From Wide-angle Seismic Modeling

Science.gov (United States)

Huang, H.; Klingelhoefer, F.

2017-12-01

The South China Sea (SCS) has undergone episodic spreading during the Cenozoic Era. The long-term extension has shaped the continental margins of the SCS, leading to a progressive breakup of the lithosphere. Separated blocks and rift troughs, as controlled by tectonic stretching, contains key information about the deforming mechanism of the crust. In this work, we present a P-wave velocity model of a wide-angle seismic profile OBS2013-1 which passes through the NW margin of the SCS. Modeling of 25 ocean bottom seismometers (OBS) data revealed a detailed crustal structure and shallow complexities along the profile (Figure 1). The crust thins symmetrically across the Xisha Trough, from more than 20 km on flanks to 10 km in the central valley where the sediments thickens over 5 km; A volcano is situated on top of the centre basement high where the Moho drops slightly. At the distal margin around the Zhongsha Trough, the upper crust was detached and accordingly made the middle crust exhumed in a narrow area ( 20 km wide). Meanwhile, materials from the lower crust rises asymmetrically, increasing the crustal velocity by 0.3 km/s and may also giving rise to volcanisms along the hanging side. A 40 km wide hyper-stretched crust (with thickness of 5 km) was identified next to the Zhongsha Trough and covered by overflowing magma and post-rift sediments on the top. These observations argue for a depth-related and asymmetrically extension of the crust, including (1) detachment fault controls the deformation of the upper crust, leading to exhumation of the middle crust and asymmetrically rising of the lower crust, (2) The region adjacent to the exhumation region and with highly thinned crust can be considered as extinct OCT due to magma-starved supplying.

Managing Vietnamese newsrooms: the role of internal communication

Vu, T.

2015-01-01

There have been many studies on news production but little has been found about newsroom efficiency despite the fact that this is journalists’ main concern. The very few (mostly foreign) researchers who study Vietnamese media usually look at them from policy making and political-social perspectives, and with an outsider’s eye. They have little physical access, if any, to the media houses, which surely limits their view. Their approach implicitly over-emphasizes the influence of political forc...

THE FREE TRADE AGREEMENT BETWEEN THE EAEU AND VIETNAM AS A FACTOR OF RUSSIAN-VIETNAMESE RELATIONS

Full Text Available The article examines the infl uence of the free trade agreement between the Eurasian Economic Union and Vietnam on  Russian-Vietnamese relations. The author considers preconditions for expansion of the EAEU, main steps of negotiations, special features  of the agreement, and results, achieved by present time. The author  pays special attention to evolution of Russian-Vietnamese relations  and also to key factors of Vietnam’s foreign policy. Russian- Vietnamese relations have been developing on the base of the USSR- Vietnam partnership in the Cold War. They were marked by stability  and high level of political contacts, but at the same time scales of economic cooperation were relatively low. Established interaction  between two states was a foundation for the dialogue for the  involvement of Vietnam in Eurasian integration. Vietnam, in turn,  tried to conduct multilateral foreign policy (including the expansion of network of free trade agreements and so it had positive attitude  for cooperation with Russia in a sphere of Eurasian integration. For  Russia, the EAEU – Vietnam free trade agreement has both political  (expansion of Eurasian integration beyond the Post-Soviet space and rise of prestige of the EAEU and economic (impact on trade and investment cooperation with the SRV signifi cance. The agreement entered into force in October 2016 and under its realization some  results have already been made. At the same time the agreement is of compromise and “test” sort. So it’s rather able to make an  immediate breakthrough in Russian-Vietnamese trade and Russian  policy in the Asia-Pacifi c in whole. But this agreement can be an  additional factor for attraction to Vietnam in Russia and enlargement of cooperation with Vietnamese counterparts.

According to the Ministry of the Interior, Department of Statistics, Taiwan, ROC (2010), Taiwan is home to 131,000 Southeast Asian female spouses holding valid resident permits. More than two thirds (68%) of this number is from Vietnam. An understanding of health-related quality of life (HRQL) among female Vietnamese spouses is essential to develop appropriate health policies and interventions for this population. The purpose of this study was to compare HRQL values between the general Taiwan female spouse population and the female Vietnamese spouses living in Taiwan. This study was conducted in a community-based health center in southern Taiwan and targeted households with Vietnamese wives in the Tainan, Kaohsiung, and Pingtung areas. A total of 203 female Vietnamese spouses were included in this study, with data collected using questionnaires between June 2007 and July 2008. Research instruments included the Demographic Inventory Scale and the 36-Item Short Form Version 2. The general population norm was based on the findings of the Center for Population and Health Survey Research, Bureau of Health Promotion, Department of Health in Taiwan (2001) using the 36-Item Short Form Version 2, with norm scoring based on 18,142 subjects aged 12 years and older. Cross-cultural comparisons indicate that Vietnamese immigrant women have a generally lower HRQL mean score than Taiwanese women in terms of seven dimensions, including physical functioning, role limitations due to physical health, general health perceptions, vitality, social functioning, role limitations due to emotional problems, and mental health. Only one domain, bodily pain, showed a slightly higher level among Vietnamese spouse respondents. This result is consistent with previous studies that indicate immigrant health status is generally lower than that of the people in the host society. High bodily pain, low vitality, somatization, social isolation, and mental health issues were discussed and should of

To examine breast cancer characteristics of women of Vietnamese ancestry living in the San Francisco Bay Area in comparison with those of other racial or ethnic groups in the same area. Data were obtained from the population-based Greater Bay Area Cancer Registry, part of the Surveillance, Epidemiology, and End Results program. We included breast cancer cases diagnosed from 1988 to 1999 and compared the age at diagnosis, stage and histologic grade at diagnosis, estrogen- and progesterone-receptor status, and surgery types across racial or ethnic groups. We also modeled the effect of patient and clinical characteristics and hospital and physician on the racial or ethnic variations in surgery type. Vietnamese women were younger at diagnosis than other racial or ethnic subgroups (mean age, 51.0 years), with 49.6% of the diagnoses occurring in patients younger than 50. They were also significantly more likely to have received mastectomy for their in situ and localized tumors (61.1% having mastectomy) than women of other racial or ethnic groups. The increased likelihood of having mastectomy among Vietnamese women was not affected greatly by age, year of diagnosis, tumor stage, histologic grade, or physician, but was partly attributable to the hospital of diagnosis. The effects of a lower mean age at diagnosis and the reasons for an unexpectedly higher percentage of mastectomies in this Asian subgroup should be further explored.

Adjustment of interbank lending in pre- and post-regulation periods: Empirical analysis of Vietnamese commercial banks

Directory of Open Access Journals (Sweden)

Ho Thanh Tung

2017-10-01

Full Text Available This article aims to analyze the interbank lending adjustment during the period when Vietnamese commercial banks are compliant with some parts of the Basel regulation framework. A pilot regulation period has started in 2011 and full application will be effective by the end of 2018. Partial adjustment models and variance decomposition are used for the analyses. In the analysis of the quarterly released financial statements of Vietnamese commercial banks in the period from 2008/Q1 to 2015/Q4, the empirical evidence showed that throughout the period, lending to non-bank and high liquidity assets contributed to the adjustment in both long run and short run with a negative association. In addition, the loan loss allowance contributed to the adjustment in the post-regulation period only with a positive association. These highly contributing factors also show a potential shock after the adjustment of the interbank lending. The results imply there is a need for interbank lending portfolio report and an efficient control over the IRB of Vietnamese commercial banks.

Australia is a multicultural society and nowhere is this more evident than in Sydney where 25% of the population speaks a language other than English. In one of the largest area health services in New South Wales, the five most frequently spoken languages at home are Arabic, Serbo-Croatian, Spanish, Turkish or Vietnamese, with these language groups comprising 12% of Sydney's population. Yet nurses speaking one of these five languages comprise less than 1% of the nursing workforce. A cost-effective method of addressing the shortage of nurses speaking languages other than English is to recruit students who already speak another language into the profession. This study examined high school students' perceptions of nursing in order to determine appropriate methods of recruiting students speaking one of these languages. Implications for the design of recruitment campaigns are also discussed.

Continental transform margins : state of art and future milestones

Science.gov (United States)

Basile, Christophe

2010-05-01

Transform faults were defined 45 years ago as ‘a new class of fault' (Wilson, 1965), and transform margins were consequently individualized as a new class of continental margins. While transform margins represent 20 to 25 % of the total length of continent-ocean transitions, they were poorly studied, especially when compared with the amount of data, interpretations, models and conceptual progress accumulated on divergent or convergent continental margins. The best studied examples of transform margins are located in the northern part of Norway, south of South Africa, in the gulf of California and on both sides of the Equatorial Atlantic. Here is located the Côte d'Ivoire - Ghana margin, where the more complete data set was acquired, based on numerous geological and geophysical cruises, including ODP Leg 159. The first models that encompassed the structure and evolution of transform margins were mainly driven by plate kinematic reconstructions, and evidenced the diachronic end of tectonic activity and the non-cylindrical character of these margins, with a decreasing strike-slip deformation from the convex to the concave divergent-transform intersections. Further thermo-mechanical models were more specifically designed to explain the vertical displacements along transform margins, and especially the occurrence of high-standing marginal ridges. These thermo-mechanical models involved either heat transfer from oceanic to continental lithospheres across the transform faults or tectonically- or gravity-driven mass transfer in the upper crust. These models were far from fully fit observations, and were frequently dedicated to specific example, and not easily generalizable. Future work on transform continental margins may be expected to fill some scientific gaps, and the definition of working directions can benefit from the studies dedicated to other types of margins. At regional scale the structural and sedimentological variability of transform continental margins has

Internet addiction (IA) is a common problem found in young Asians. This study aimed to study the influence of IA and online activities on health-related quality of life (HRQOL) in young Vietnamese. This study also compared the frequencies of anxiety, depression and other addiction of young Vietnamese with and without IA. This study recruited 566 young Vietnamese (56.7% female, 43.3% male) ranging from 15 to 25 years of age via the respondent-driven sampling technique. Chi-squared, t-test and analysis of variance were used to compare young Vietnamese with and without IA. Regression analyses were used to examine the association between internet usage characteristics and HRQOL. Results from this cross-sectional study showed that 21.2% of participants suffered from IA. Online relationship demonstrated significantly higher influences on behaviors and lifestyles in participants with IA than those without IA. Participants with IA were more likely to have problems with self-care, difficulty in performing daily routine, suffer from pain and discomfort, anxiety and depression. Contrary to previous studies, we found that there were no differences in gender, sociodemographic, the number of participants with cigarette smoking, water-pipe smoking and alcohol dependence between the IA and non-IA groups. IA was significantly associated with poor HRQOL in young Vietnamese. IA is a common problem among young Vietnamese and the prevalence of IA is the highest as compared to other Asian countries. Our findings suggest that gender may not play a key role in IA. This can be an emerging trend when both genders have equal access to the internet. By studying the impact of IA on HRQOL, healthcare professionals can design effective intervention to alleviate the negative consequences of IA in Vietnam.

Full Text Available The main purpose of this study is to examine the relationship between organisational culture (OC and Total Quality Management (TQM, and the influence of TQM implementation on organisational performance improvement within the context of the Vietnamese construction industry. A survey was conducted with 104 respondents from Vietnamese construction firms, using validated survey instruments developed in past research. Analysis techniques include cluster analysis and Structural Equation Modelling. Findings showed that Vietnamese construction firms are dominated by clan and hierarchy cultures rather than adhocracy and market cultures according to Competing Value Framework (CVF of OC classification. Furthermore, it was found that organisations dominated by either clan or adhocracy cultures could provide a favourable environment for successful TQM implementation, whereas this is not the case for those dominated by both market and hierarchy cultures. This study also confirmed the significant and positive relationship between TQM implementation and organisational performance improvement.

RFS was significantly worse in Vietnamese children (hazards ratio=4.48; 95% confidence interval [CI], 2.16-9.3; PVietnamese children, respectively. In the latter group, relapses occurred in bone marrow and cerebrospinal fluid at a much earlier stage. The outcome was compared at first relapse only because of different treatments afterward, according to the country. Both series were similar for sex, age at diagnosis, initial white blood cell count, cytogenetic abnormalities, and corticosensitivity at day 8. Higher frequency of L2-acute lymphoblastic leukemia (PVietnamese children. Several factors may contribute to the poor RFS in Vietnamese children, which include the time interval before the first intrathecal therapy and differences in the management of drug-related toxicity. However, additional contribution of socioeconomic factors and/or variations in pharmacogenetic polymorphisms in Vietnamese patients cannot currently be ruled out.

Cenozoic basalts in Indo-China are part of a regional melting episode along the rifted Eurasian margin. Trace element and isotopic compositions of Vietnamese basalts are used to place constraints on the extent of lithospheric and asthenosphere contributions to the melts and possible mantle dynamic implications. The {sup 87}Sr/{sup 86}Sr, {sup 207}Pb/{sup 204}Pb, and {sup 208}Pb/{sup 204}Pb isotopic ratios of the basalts reflect minimal crustal wall rock reaction, and variable enrichment in EM1 and EM2 of a {sup 208}Pb-rich MORB-like source. Some, but not all, of this variation corresponds to the age of lithospheric sector penetrated. Basalts erupted through a cratonic, central sector (e.g. at Quang Ngai, Pleiku, Song Cau, Kong Plong, and Buon Ma Thuot) and off-cratonic, southwest sector (e.g. Phuoc Long) resemble those of EM2-rich basalts from southern and southeaster China and the South China Sea. Basalts from an off-cratonic, southeast sector (e.g. from Dalat, Xuan Loc, and the offshore Ile des Cendres-Phu Cuy complex) reflect mixing between a low- {sup 206}Pb/{sup 204}Pb, high-{sup 208}Pb/{sup 204}Pb, EM1-like component, and resemble basalts from northwest Taiwan, eastern and northeastern China, and parts of the Japan Sea. While EM2 tends to characterise lithospheric sectors, presence of EM1 in off-cratonic rather than cratonic basalts implies an asthenosphere rather than lithospheric source. Pervasive presence of EM1 in southeast Asian and marginal basin asthenosphere corresponds with thermally-anomalous mantle and may involve delaminated cratonic substrate entrained by mobile, extruded asthenosphere.

Full Text Available Cervical cancer remains commonly diagnosed in Vietnamese American women. Despite efforts to increase cervical cancer screening among Vietnamese American women, participation rates are persistently lower than the national goal. The objective of this study is to explore beliefs of Vietnamese American women about cervical cancer, cervical cancer screening, and cancer prevention vaccines. A qualitative descriptive investigation captured group perceptions about meaning and beliefs of cervical cancer, screening, and cancer prevention vaccines, and participants’ stories using a community-based participatory research approach. Forty Vietnamese American women were recruited from the Portland, Oregon metropolitan area into four focus groups. Using a process of directed content analysis, focus group transcripts were coded for themes. We found that cervical cancer continues to be a difficult topic to discuss, and Vietnamese American women may not bring the topic up themselves to their health care providers. Some women experienced intense emotions of fear or shame of having their cervix examined. Women delayed seeking cervical cancer screening and needed to have early warning signs, which guided them as to when to seek health care. Women focused on cleanliness through vaginal and/or perineal washing as primary prevention for cervical cancer. There were limited awareness and knowledge about cancer prevention vaccines, specifically the human papillomavirus. Some women relied heavily on their informal social networks of family, friends, or community for health knowledge. Fear and misunderstanding dominated the beliefs of Vietnamese American women about cervical cancer screening and prevention. These findings underscored the importance of having culturally-specific findings, which will inform a multicomponent intervention to promote cervical cancer screening and cancer prevention vaccine uptake within this population.

Background: Collaboration is a common occurrence among Vietnamese scientists; however, insights into Vietnamese scientific collaborations have been scarce. On the other hand, the application of social network analysis in studying science collaboration has gained much attention all over the world. The technique could be employed to explore Vietnam's scientific community. Methods: This paper employs network theory to explore characteristics of a network of 412 Vietnamese social scientists whose papers can be found indexed in the Scopus database. Two basic network measures, density and clustering coefficient, were taken, and the entire network was studied in comparison with two of its largest components. Results: The networks connections are very sparse, with a density of only 0.47%, while the clustering coefficient is very high (58.64%). This suggests an inefficient dissemination of information, knowledge, and expertise in the network. Secondly, the disparity in levels of connection among individuals indicates that the network would easily fall apart if a few highly-connected nodes are removed. Finally, the two largest components of the network were found to differ from the entire networks in terms of measures and were both led by the most productive and well-connected researchers. Conclusions: High clustering and low density seems to be tied to inefficient dissemination of expertise among Vietnamese social scientists, and consequently low scientific output. Also low in robustness, the network shows the potential of an intellectual elite composed of well-connected, productive, and socially significant individuals.

Long-term landscape evolution of the South Atlantic "passive" continental margin in Eastern Argentina using apatite fission-track thermochronology

To understand the evolution of the "passive" continental margin in Argentina low temperature thermochronology is an appropriate method, which might lead to new insights in this area. The Tandilia System, also called Sierras Septentrionales, is located south of the Río de la Plato Craton in eastern Argentina in the state of Buenos Aires. North of the hills the Salado basin is located whereas the Claromecó basin is situated south of the mountain range. In contrary to most basins along the South American "passive" continental margin, the Tandilia-System and the neighbouring basins trend perpendicular to the coast line. The topography is fairly flat with altitudes up to 350 m. The igneous-metamorphic basement is pre-Proterozoic in age and build up of mainly granitic-tonalitic gneisses, migmatites, amphibolites, some ultramafic rocks and granitoid plutons. It is overlain by a series of Neoproterozoic to early Paleozoic sedimentary rocks (Cingolani 2011), like siliciclastic rocks, dolostones, shales and limestones (Demoulin 2005). The aim of the study is to quantify the long-term landscape evolution of the "passive" continental margin in eastern Argentina in terms of thermal, exhumation and tectonic evolution. For that purpose, samples were taken from the basement of the Sierra Septentrionales and analyzed with the apatite fission-track method. Further 2-D thermokinematic modeling was conducted with the computer code HeFTy (Ketcham 2005; Ketcham 2007; Ketcham et al. 2009). Because there are different hypotheses in literature regarding the geological evolution of this area two different models were generated, one after Demoulin et al. (2005) and another after Zalba et al.(2007). All samples were taken from the Neoproterozoic igneous-metamorphic basement. Apatite fission-track ages range from 101.6 (9.4) to 228.9 (22.3) Ma, and, therefore, are younger than their formation age, indicating all samples have been thermally reset. Six samples accomplished enough confined

Southeast Asians have higher rates of liver cancer than any other racial/ethnic group in the United States. Chronic carriage of hepatitis B virus (HBV) is the most common underlying cause of liver cancer in the majority of Asian populations. Our objectives were to describe Vietnamese Americans’ awareness of hepatitis B, levels of HBV testing, and knowledge about hepatitis B transmission; and to compare the HBV knowledge and practices of men and women. A community-based, in-person survey of Vietnamese men and women was conducted in Seattle during 2002. Seven hundred and fifteen individuals (345 men and 370 women) completed the questionnaire. Eighty-one percent of the respondents had heard of hepatitis B (76% of men, 86% of women) and 67% reported HBV testing (66% of men, 68% of women). A majority of the participants knew that HBV can be transmitted during sexual intercourse (71% of men, 68% of women), by sharing toothbrushes (67% of men, 77% of women), and by sharing razors (59% of men, 67% of women). Less than one-half knew that hepatitis B is not spread by eating food prepared by an infected person (46% of men, 27% of women), nor by coughing (39% of men, 25% of women). One-third of our respondents did not recall being tested for HBV. Important knowledge deficits about routes of hepatitis B transmission were identified. Continued efforts should be made to develop and implement hepatitis B educational campaigns for Vietnamese immigrant communities. These efforts might be tailored to male and female audiences.

Culture impacts help-seeking preferences. We examined Vietnamese Americans' help-seeking preferences for depressive symptoms, through a telephone survey (N = 1666). A vignette describing an age- and gender-matched individual with depression was presented, and respondents chose from a list of options and provided open-ended responses about their help-seeking preferences. Results showed that 78.3% would seek professional help, either from a family doctor, a mental health provider, or both; 54.4% preferred to seek help from a family doctor but not from a mental health provider. Most (82.1%) would prefer to talk to family or friends, 62.2% would prefer to look up information, and 50.1% would prefer to get spiritual help. Logistic regression analysis revealed that preferences for non-professional help-seeking options (such as talking to friends or family, looking up information, and getting spiritual help), health care access, and perceived poor health, were associated with increased odds of preferring professional help-seeking. This population-based study of Vietnamese Americans highlight promising channels to deliver education about depression and effective help-seeking resources, particularly the importance of family doctors and social networks. Furthermore, addressing barriers in access to care remains a critical component of promoting professional help-seeking.

Fever is the most common symptom in pediatric healthcare. Providing parents with better information on childhood fever management can improve their cognition and home-care abilities. Vietnamese female spouse comprise the largest segment of women who have emigrated from Southeast Asia to Taiwan over the past two decades. After arrival to Taiwan, they have to encounter the events of pregnancy and being a mother. In health care services, language barriers and cultural issues are key healthcare-related barriers to the adaptation of these women to Taiwan society. This study assessed the efficacy of using Vietnamese-language fever management education materials in changing the fever management behaviors of Vietnamese mothers living in Taiwan. This experimental study used a randomly assigned, pre- and post-test approach. A snowball method was used to recruit Vietnamese women living in southern Taiwan with children under 6 years of age. Participants were randomly assigned to experimental (n = 31, Vietnamese-language fever management brochure + VCD) and comparison (n = 30, Chinese-language brochure + VCD) groups. Both groups achieved significantly improvement scores in (fever) information, attitudes, self-efficacy and skills, with improvements significantly higher in the experimental group than the comparison group. This study supports that fever management education presented in the recipient's primary language effectively improves recipient fever management knowledge, attitudes, skills, and self-efficacy.

Agent Orange, a phenoxyherbicide mixture of 2,4,5-trichlorophenoxyaceticacid (2,4,5-T) and 2,4- dichlorophenoxyacetic acid (2,4-D) was sprayed for reasons of defoliation in large amounts on about 10 % of southern Vietnam during the Vietnam war between 1962-1971. 2,4,5-T was contaminated with the highly toxic and persistent 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) in the low ppm-range (mg/kg). In samples collected between 1970 and 1973 Baughman et al., 1973 documented elevated levels of TCDD from Agent Orange in milk samples from southern Vietnamese woman as well as in fish and shrimp samples from sprayed areas in this region. Studies have documented the intake of 2,3,7,8-TCDD from Agent Orange in Vietnamese and in among US war veterans. This paper gives an overview on recent findings for PCDDs/Fs and dioxin-like PCBs and in various environmental compartments, in humans and in food. Due to the fact that 2,3,7,8-TCDD is the major dioxin congener in 2,4,5-T, many investigators focused mainly on TCDD. We found from our own investigations, that TCDD in case of dioxin contamination is still the predominant dioxin congener, but in certain instances we also found other elevated congeners as well. In some cases mixed chemical contamination of food or humans was found - originating from Agent Orange and other sources. The paper will explain the potential origin of some of the other contaminations found.

Contrasting sedimentary processes along a convergent margin: the Lesser Antilles arc system

Science.gov (United States)

Picard, Michel; Schneider, Jean-Luc; Boudon, Georges

2006-12-01

Sedimentation processes occurring in an active convergent setting are well illustrated in the Lesser Antilles island arc. The margin is related to westward subduction of the North and/or the South America plates beneath the Caribbean plate. From east to west, the arc can be subdivided into several tectono-sedimentary depositional domains: the accretionary prism, the fore-arc basin, the arc platform and inter-arc basin, and the Grenada back-arc basin. The Grenada back-arc basin, the fore-arc basin (Tobago Trough) and the accretionary prism on the east side of the volcanic arc constitute traps for particles derived from the arc platform and the South American continent. The arc is volcanically active, and provides large volumes of volcaniclastic sediments which accumulate mainly in the Grenada basin by volcaniclastic gravity flows (volcanic debris avalanches, debris flows, turbiditic flows) and minor amounts by fallout. By contrast, the eastern side of the margin is fed by ash fallout and minor volcaniclastic turbidites. In this area, the dominant component of the sediments is pelagic in origin, or derived from South America (siliciclastic turbidites). Insular shelves are the locations of carbonate sedimentation, such as large platforms which develop in the Limestone Caribbees in the northern part of the margin. Reworking of carbonate material by turbidity currents also delivers lesser amounts to eastern basins of the margin. This contrasting sedimentation on both sides of the arc platform along the margin is controlled by several interacting factors including basin morphology, volcanic productivity, wind and deep-sea current patterns, and sea-level changes. Basin morphology appears to be the most dominant factor. The western slopes of the arc platform are steeper than the eastern ones, thus favouring gravity flow processes.

Agricultural activities in Vietnam generate about 62 million tonnes of biomass (rice straw, rice husk, bagasse, corn cob, corn stover, etc.) annually. In this work, four different types of biomass from Vietnam, namely rice straw, rice husk, factory bagasse, and corn cob, have been studied as potential raw materials to produce bio-oil by fast pyrolysis technology. Test runs were conducted in a fluidized-bed reactor at a temperature of 500 °C and residence time less than 2 s. Size and moisture content of the feed were less than 2 mm and 2%, respectively. It was found that yields of bio-oil as a liquid product obtained from pyrolysis of these feedstocks were more than 50% and that obtained from the bagasse was the highest. Bio-oil quality from Vietnamese biomass resources satisfies ASTM D7544-12 standard for pyrolysis liquid biofuels. These results showed the potential of using biomass in Vietnam to produce bio-oil which could be directly used as a combustion fuel or upgraded into transportation fuels and chemicals. - Highlights: • Four types of Vietnamese biomass were firstly analyzed in detail. • Optimal conditions for fast pyrolysis reaction for Vietnamese biomass types. • Bio-oil product adapted to the standard specification for pyrolysis liquid biofuel

Tinivella, U.; Loreto, M.F.; Accaino, F. [Inst. Nazionale di Oceanografia di Geofisica Sperimentale, Trieste (Italy)

2008-07-01

The presence of gas hydrate and free gas within marine sediments, deposited along the South Shetland margin, offshore the Antarctic Peninsula, was confirmed by low and high resolution geophysical data, acquired during three research cruises in 1989-1990. Seismic data analysis has demonstrated the presence of a bottom simulating reflector that is very strong and continuous in the eastern part of the margin. This seismic dataset was used in the past to extract detailed velocity information of the shallow structures by using traditional tomographic inversion and jointly tomographic inversion and pre-stack depth migration tool. This paper presented a method to obtain a regional seismic velocity field and information about hydrate and free gas presence in the marine sediments, by using an improved method of the standard analysis of the pre-stack depth migration output. The velocity field was obtained with a layer stripping approach and tomographic inversion of the reflections observed in common image gathering. The paper presented the seismic data and regional and detailed velocity analysis. The results of residual semblance analyses were also presented. Gas phase concentrations were then discussed. The velocity analysis revealed the presence of three main layers characterizing the first kilometer of sediments below the sea floor. In addition, velocity models and related gas-phase sections showed that gas was concentrated in different parts of the profile than where the hydrate was concentrated. This observation confirmed that geological structures and sedimentary processes controlled the gas and hydrate distribution, as observed along other margins. 7 refs., 5 figs.

New Insight Into the Crustal Structure of the Continental Margin offshore NW Sabah/Borneo

Science.gov (United States)

Barckhausen, U.; Franke, D.; Behain, D.; Meyer, H.

2002-12-01

The continental margin offshore NW Sabah/Borneo (Malaysia) has been investigated with reflection and refraction seismics, magnetics, and gravity during the recent cruise BGR01-POPSCOMS. A total of 4000 km of geophysical profiles has been acquired, thereof 2900 km with reflection seismics. The focus of investigations was on the deep water areas. The margin looks like a typical accretionary margin and was presumably formed during the subduction of a proto South China Sea. Presently, no horizontal movements between the two plates are being observed. Like in major parts of the South China Sea, the area seaward of the Sabah Trough consists of extended continental lithosphere which is characterised by a pattern of rotated fault blocks and half grabens and a carbonate platform of Early Oligocene to Early Miocene age. We found evidence that the continental crust also underlies the Sabah Trough and the adjacent continental slope, a fact that raises many questions about the tectonic history and development of this margin. The tectonic pattern of the Dangerous Grounds' extended continental crust can be traced a long way landward of the Sabah Trough beneath the sedimentary succession of the upper plate. The magnetic anomalies which are dominated by the magnetic signatures of relatively young volcanic features also continue under the continental slope. The sedimentary rocks of the upper plate, in contrast, seem to generate hardly any magnetic anomalies. Based on the new data we propose the following scenario for the development of the NW Sabah continental margin: Seafloor spreading in the present South China Sea started at about 30 Ma in the Late Oligocene. The spreading process separated the Dangerous Grounds area from the SE Asian continent and ceased in late Early Miocene when the oceanic crust of the proto South China Sea was fully subducted in eastward direction along the Borneo-Palawan Trough. During Lower and/or Middle Miocene, Borneo rotated counterclockwise and was

The continental margins of the marginal seas is largely shaped by a complex interplay of sediment transport processes directed both downslope and along-slope. Factors influence the sediment transport from shelf to the deep basin include: (i) seabed morphology, (ii) climate, (iii) sea level changes, (iv) slope stability, (v) oceanographic regime, and (vi) sediment sources. In order to understand the recent sedimentary processes along the western margin of the South Korea Plateau in the East Sea, we collected multiple geophysical datasets including the subbottom profiler and multibeam echosounder as well as geological sampling. Twelve echo types have been defined and interpreted as deposits formed by shallow marine, hemipelagic sedimentation, bottom currents, combined- (mass-movement/hemipelagic and hemipelagic/turbidites) and mass-movement-processes. Hemipelagic sedimentation, which is reflected as undisturbed layered sediments, appears to have been the primary sedimentary process throughout the study area. Two major slope-parallel channels appear to have acted as major conduits for turbidity currents from shallower shelf into the deep basins. Bottom current deposits, which is expressed as undulating seafloor morphology, are prevalent in the southern mid-slope at water depths between 250 to 450 m. Mass-transport deposits, consisting of chaotic seismic facies, occur in the upper and lower parts of the continental slope. Piston cores confirm the presence of MTDs that are characterized by mud clasts of variable size and shape. Multibeam bathymetry data show that these MTDs chiefly initiate on lower-slopes (400-600 m) where the gradient is up to 3°. In addition, subbottom profiles suggest the presence of numerous faults in close vicinity of headwall scarps; some are extending to the seafloor suggesting their recent activity. Earthquakes associated with tectonic activity are considered as the main triggering mechanism for these MTDs. Overall, the acoustic facies

MARGINALIZATION OF SOUTH ASIANS BASED ON THE RACE AND SKIN COLOR IN BHARATI MUKHERJEE’S "JASMINE" AND CHITRA B. DIVAKARUNI’S "THE MISTRESS OF SPICES"

Directory of Open Access Journals (Sweden)

Iwona Filipczak

2016-04-01

Full Text Available The purpose of this article is to focus on the issue of marginalization of South Asians in the United States as portrayed in two novels written by writers of Indian origin: Bharati Mukherjee’s "Jasmine" and Chitra Bannerjee Divakaruni’s "The Mistress of Spices". It is investigated how race or skin color are the reasons for the marginalization of Indian immigrants in the United States. While "Jasmine" shows white Americans’ inability to embrace the racial difference of an Indian immigrant, which may be read as a reflection of the relative newness of this ethnic group in the United States and its shifting racial classification, "The Mistress of Spices" shows that the patterns of marginalization based on skin color may be developed already in the homeland, India, and then transferred to the US and confronted with the country’s racial diversity. Divakaruni’s novel raises a discussion of how the appreciation of whiteness developed in the country of birth leads to the hierarchical relations between the members of the Indian diaspora, and how it affects their relations with other American minorities. In this way, it shows that marginalization based on skin color is not only the outcome of inter-ethnic encounters but it can be an internal problem of this ethnic group as well.

This study prospectively evaluates the relationship between unaccompanied status and levels of psychological distress in a group of Vietnamese Amerasians both prior to, and during, migration. Its objective was to determine whether unaccompanied migrant status functions as an independent post-departure risk factor for psychological distress, or if unaccompanied migrants are already at increased risk for, and have higher levels of, psychological distress prior to departure and the acquisition of unaccompanied status. Seventy-five Vietnamese Amerasian youth were evaluated at two points during their migration utilizing Felsman's Personal Information Form, the Hopkins Symptom Checklist-25, and the Youth Self-Report. The first assessment was conducted prior to migration at the Amerasian Transit Center in Vietnam, and the second during migration at the Philippine Refugee Processing Center. Unaccompanied Amerasians were found to have significantly higher risk levels for, and significantly more symptoms of, psychological distress prior to migration than accompanied Amerasians. During migration the difference in levels of psychological distress between accompanied and unaccompanied Amerasians increased beyond that attributable to predeparture risk levels alone. This significant differential increase in levels of psychological distress among unaccompanied Amerasians is attributable to unaccompanied status. Unaccompanied migrant status thus appears to function both as an independent postdeparture risk factor for psychological distress and also as a marker for increased levels of risk and psychological distress prior to migration.

Neotectonic activity in South Africa has only recently received attention despite the fact that a rigorous knowledge of this phenomenon could have a major impact on industrial development within certain areas. Since the early 1980s the Atomic Energy Corporation of South Africa has addressed this specific problem in the process of detailed site investigations for the licensing of six facilities related to the nuclear industry. The data indicates that there is a general correspondence in five selected areas along the South African coast between the development of Quarternary joints/faults and the degree of seismic activity recorded in each geological domain. Finally, the results provide new data that may add to a recent survey of global tectonic stresses. 13 refs., 1 fig

Objectives The average alcohol consumption per capita among Vietnamese adults has consistently increased. Although alcohol-related disorders have been extensively studied, there is a paucity of research shedding light on this issue among Internet users. The study aimed to examine the severity of alcohol-related disorders and other associated factors that might predispose individuals towards alcohol usage in a sample of youths recruited online. Methods An online cross-sectional study was conducted with 1,080 Vietnamese youths. A standardized questionnaire was used. Respondent-driven sampling was applied to recruit participants. Multivariate logistic and Tobit regressions were utilized to identify the associated factors. Results About 59.5% of the males and 12.7% of the total youths declared that they were actively using alcohol. From the total sample, a cumulative total of 32.3% of the participants were drinking alcohol, with 21.8% and 25.0% of the participants being classified as drinking hazardously and binge drinkers, respectively. The majority of the participants (60.7%) were in the pre-contemplative stage. Conclusions A high prevalence of hazardous drinking was recognized among online Vietnamese youths. In addition, we found relationships between alcohol use disorder and other addictive disorders, such as tobacco smoking and water-pipe usage. Our results highlighted that the majority of the individuals are not receptive to the idea of changing their alcohol habits, and this would imply that there ought to be more government effort towards the implementation of effective alcohol control policies.

Eating out of home (OH) is nutritionally important in some developing countries. This study identifies the factors associated with eating OH in Vietnamese adolescents. Data were obtained from a cross-sectional cluster survey of 502 adolescents in rural and urban areas in Vietnam. Factors associated with eating OH were recorded with a Likert scale and analysed using factor analysis. Data on eating OH was collected using a frequency questionnaire and a 1-day 24h recall. A first pattern "Convenience" incorporated preparation time, price, variety, taste, proximity and social aspects as items associated with eating OH. A second pattern "Nutritional and food safety concerned" reflected concerns with regard to hygiene, fat and salt content of the food prepared OH. Adolescents characterised by the convenience pattern were more likely (OR=1.51, Peat OH more frequently. The highest tertile of the Nutritional and food safety concerned pattern was less likely (OR=0.61, P=0.03) to eat OH compared to lower tertiles. Both patterns were not associated with the % energy from eating OH per day. Convenience and to a lesser extent Nutritional and food safety concerns are significant factors associated with the frequency of eating OH in Vietnamese adolescents. Copyright © 2011 Elsevier Ltd.

To describe the smoking behaviour and possible reasons for delayed uptake of tobacco smoking among Arabic and Vietnamese/Asian speaking senior school students in Sydney A descriptive study involving four adult in-depth interviews and five student focus groups plus a quantitative survey of 2,573 school students attending Years 10 and 11 from 12 high schools with high Vietnamese and Arabic populations was conducted in Sydney in 1998. Self-reported smoking behaviour and peer, parent, school and cultural background information was collected. Students who smoke were more likely to have more than $20 a week pocket money, be from an English-speaking background, have no rules at home about smoking, have family members who smoke, not feel close to their father, spend three or more evenings a week out with friends, and have negative perceptions of the school environment and of the level of teacher support. They were less likely to smoke if they perceived their peers to be unsupportive. These results confirm the delayed uptake of smoking among students from a Vietnamese/Asian and Arabic-speaking backgrounds compared with those from an English-speaking background. A number of family and school factors were associated with smoking. Positive parental modelling, active parenting including awareness of or supervision of student leisure time, strict rules about not smoking and less pocket money are important strategies for preventing smoking among all adolescents.

Aggregate Settling Velocities in San Francisco Estuary Margins

One way that humans impact aquatic ecosystems is by adding nutrients and contaminants, which can propagate up the food web and cause blooms and die-offs, respectively. Often, these chemicals are attached to fine sediments, and thus where sediments go, so do these anthropogenic influences. Vertical motion of sediments is important for sinking and burial, and also for indirect effects on horizontal transport. The dynamics of sinking sediment (often in aggregates) are complex, thus we need field data to test and validate existing models. San Francisco Bay is well studied and is often used as a test case for new measurement and model techniques (Barnard et al. 2013). Settling velocities for aggregates vary between 4*10-5 to 1.6*10-2 m/s along the estuary backbone (Manning and Schoellhamer 2013). Model results from South San Francisco Bay shoals suggest two populations of settling particles, one fast (ws of 9 to 5.8*10-4 m/s) and one slow (ws of Brand et al. 2015). While the open waters of San Francisco Bay and other estuaries are well studied and modeled, sediment and contaminants often originate from the margin regions, and the margins remain poorly characterized. We conducted a 24 hour field experiment in a channel slough of South San Francisco Bay, and measured settling velocity, turbulence and flow, and suspended sediment concentration. At this margin location, we found average settling velocities of 4-5*10-5 m/s, and saw settling velocities decrease with decreasing suspended sediment concentration. These results are consistent with, though at the low end of, those seen along the estuary center, and they suggest that the two population model that has been successful along the shoals may also apply in the margins.

An internship program between Vietnamese student teachers from Cantho University and Thai graduate students from Srinakharinwirot University has occurred in June 2016. There were six Vietnamese student teachers and four Thai graduate students participated in this program with the help of science teachers from two schools in Sa Kaeo and Chachoengsao Provinces of Thailand. To explore Vietnamese and Thai students' life experiences and their perceptions in science and Mathematics teaching, reflective journals were used to record their progress as team teaching in primary and lower secondary classrooms in the form of the online format via social media in English language. The data were collected from 54 reflective journals from their eight days experiences at the schools. The data were analyzed qualitatively using Van Manen's level of reflectivity which composed of three levels; 1) Technical Rationality (TR), 2) Practical Action (PA) and 3) Critical Reflection (CR). The results explicitly revealed that the three levels of reflectivity have appeared in the reflective journals. Besides, Vietnamese and Thai students have learned more from each other and can exchange their educational experiences and culture. Certainly, this was the first time for them to teach science and mathematics in English to Thai students. Moreover, they have shared their impressions toward schools, teachers and also students in the schools in their reflective journal as well.

Smoking prevalence is high among limited English-proficient Chinese and Vietnamese American men, who are frequently unmotivated to quit and who underutilize smoking cessation resources. This study applied lay health worker outreach to leverage peer and family networks to promote smoking cessation among these men. We integrated qualitative formative research findings and Social Network Theory to develop a social-network family-focused intervention. In a pilot single-group trial, 15 lay health workers recruited 96 dyads (N = 192, 75% Vietnamese) of Chinese or Vietnamese male daily smokers and their family members and delivered the intervention consisting of two small group education sessions and two individual telephone calls over 2 months. At baseline, 42% of smokers were at precontemplation. At 3 months following the initiation of the intervention, 7-day and 30-day point prevalence smoking abstinence rates as reported by smokers and independently corroborated by family members were 30% and 24%, respectively. Utilization of smoking cessation resources (medication, quitline, physician's advice) increased from 2% to 60% (P Vietnamese smokers appears to be acceptable, feasible, and potentially efficacious. Findings warrant evaluation of long-term efficacy of the intervention in a larger scale randomized controlled trial. © The Author 2015.

Despite a number of studies in areas of focused methane seepage, the extent of transitional sediments of more diffuse methane seepage, and their influence upon biological communities is poorly understood. We investigated an area of reducing sediments with elevated levels of methane on the South Georgia margin around 250 m depth and report data from a series of geochemical and biological analyses. Here, the geochemical signatures were consistent with weak methane seepage and the role of sub-surface methane consumption was clearly very important, preventing gas emissions into bottom waters. As a result, the contribution of methane-derived carbon to the microbial and metazoan food webs was very limited, although sulfur isotopic signatures indicated a wider range of dietary contributions than was apparent from carbon isotope ratios. Macrofaunal assemblages had high dominance and were indicative of reducing sediments, with many taxa common to other similar environments and no seep-endemic fauna, indicating transitional assemblages. Also similar to other cold seep areas, there were samples of authigenic carbonate, but rather than occurring as pavements or sedimentary concretions, these carbonates were restricted to patches on the shells of Axinulus antarcticus (Bivalvia, Thyasiridae), which is suggestive of microbe-metazoan interactions.

Bone mass decreases along with aging, especially for women after menopause because of lower estrogen secretion together with low calcium intake. This study was conducted to study the effect of eggshell calcium supplementation on bone mass in 54 postmenopausal Vietnamese women living in a farming area about 60 km from Hanoi, Vietnam. Sets of 3 subjects matched by age, bone mass, BMI and calcium intake were divided randomly into 3 groups with 18 subjects in each group. The eggshell calcium group was administered 300 mg/d calcium from eggshell, the calcium carbonate group 300 mg/d calcium from calcium carbonate and the placebo group received no calcium supplementation. Bone mass (Speed of Sound (SOS)) was measured at the beginning (the baseline), the middle (6th month) and the end of the study (12th month) by the single blind method. SOS of the eggshell group increased significantly at 12 mo (p0.05). In conclusion, eggshell calcium was more effective in increasing bone mass than calcium carbonate in postmenopausal Vietnamese women.

Coral bleaching on high-latitude marginal reefs at Sodwana Bay, South Africa

2002-12-01

Coral bleaching, involving the expulsion of symbiotic zooxanthellae from the host cells, poses a major threat to coral reefs throughout their distributional range. The role of temperature in coral bleaching has been extensively investigated and is widely accepted. A bleaching event was observed on the marginal high-latitude reefs of South Africa located at Sodwana Bay during the summer months of 2000. This was associated with increased sea temperatures with high seasonal peaks in summer and increased radiation in exceptionally clear water. The bleaching was limited to Two-mile Reef and Nine-mile Reef at Sodwana Bay and affected <12% of the total living cover on Two-mile Reef. Montipora spp., Alveopora spongiosa and Acropora spp. were bleached, as well as some Alcyoniidae (Sinularia dura, Lobophytum depressum, L. patulum). A cyclical increase in sea temperature (with a period of 5-6 years) was recorded during 1998-2000 in addition to the regional temperature increase caused by the El Nino Southern Oscillation phenomenon. The mean sea temperature increased at a rate of 0.27 deg. C year{sup -1} from May 1994 to April 2000. High maximum temperatures were measured (>29 deg. C). The lowest mean monthly and the mean maximum monthly temperatures at which coral bleaching occurred were 27.5 and 28.8 deg. C, respectively, while the duration for which high temperatures occurred in 2000 was 67 days at {>=}27.5 deg. C (4 days at {>=}28.8 deg. C). Increased water clarity and radiation appeared to be a synergistic cause in the coral bleaching encountered at Sodwana Bay.

2017-12-01

The South China Sea (SCS) is one of the largest marginal sea on southeast Asia continental margin, developed Paleogene extension-rifting continental margin system which is rare in the world and preserving many deformed characterizes of this kind system. With the investigation of the SCS, guiding by the development of tectonics and geo-physics, especially the development of tectonics and the high quality seismic data based on the development of geo-physics, people gradually accept that the northern margin of the SCS has some detachment basin characterizes. After researching the northern margin of the SCS, we come up with lithosphere profiles across the shelf, slope and deep sea basin in the northeast of the SCS to confirm the tectonic style of ocean-continental transition and the property of the detachment fault. Furthermore, we describe the outline of large detachment basins at northern SCS. Based on the large number of high-quality 2D and 3D deep seismic profile(TWT,10s), drilling and logging data, combined with domestic and international relevant researches, using basin dynamics and tectono-stratigraphy theory, techniques and methods of geology and geophysics, qualitative and quantitative, we describe the formation of the detachment basin and calculate the fault activity rate, stretching factor and settlement. According to the research, we propose that there is a giant and complete detachment basin system in the northern SCS and suggest three conclusions. First of all, the detachment basin system can be divided into three domains: proximal domain covering the Yangjiang Sag, Shenhu uplift and part of Shunde Sag, necking zone covering part of the Shunde Sag and Heshan Sag, distal domain covering most part of Heshan Sag. Second, the difference of the stretching factor is observed along the three domains of the detachment basin system. The factor of the proximal domain is the minimum among them. On the other side, the distal domain is the maximum among them. This

Nemo Solus Satis Sapit: Trends of Research Collaborations in the Vietnamese Social Sciences, Observing 2008–2017 Scopus Data

Full Text Available “Nemo solus satis sapit”—no one can be wise enough on his own. This is particularly true when it comes to collaborations in scientific research. Concerns over this issue in Vietnam, a developing country with limited academic resources, led to an in-depth study on Vietnamese social science research, using Google Scholar and Scopus, during 2008–2017. The results showed that more than 90% of scientists had worked with colleagues to publish, and they had collaborated 13 times on average during the time limit of the data sample. These collaborations, both domestic and international, mildly boosted author performance. On the other hand, the modest number of publications by Vietnamese authors was reportedly linked to Vietnamese social scientists’ heavy reliance on collaborative work as non-leading co-authors: for an entire decade (2008–2017, the average author assumes the leading role merely in two articles, and hardly ever published alone. This implies that policy-makers ought to consider promoting institutional collaborations while also encouraging authors to acquire the experience of publishing solo.

The Perceived Stress Scale 10 item (PSS-10) has been translated into more than 20 languages and used widely in different populations. Yet, to date, no study has tested psychometric properties of the instrument among older women and there is no Vietnamese version of the instrument. This study translated the PSS-10 into Vietnamese and assessed Vietnamese version of the Perceived Stress Scale 10 items (V-PSS-10) for translation equivalence, face validity, construct validity, correlations, internal consistency reliability, and test-retest reliability among 473 women aged 60 and over. The study found that V-PSS-10 retained the original meaning and was understood by Vietnamese older women. An exploratory factor analysis of the V-PSS-10 yielded a two-factor structure, and these two factors were significantly correlated (0.56, p < .01) with all item loadings exceeded .50. The V-PSS-10 score was positively correlated with general sleep disturbance (ρ = .12, p < .05), CES-D score for depression symptoms (ρ = .60, p < .01), and negatively correlated with mental (ρ = -.46, p < .01), and physical health scores (ρ = -.19, p < .01). The Cronbach's alpha for the V-PSS-10 was .80, and the test-retest correlation at one month's interval was .43. Findings from this study suggest that the V-PSS-10 has acceptable validity and reliability levels among older women. The V-PSS-10 can be used to measure perceived stress in future research and practice. However, future research would be useful to further endorse the validity and reliability of the V-PSS-10.

Population-based studies have reported high rates of smoking prevalence among Chinese and Vietnamese American men. Although nicotine replacement therapy (NRT) is effective, recommended, and accessible without prescription, these populations underuse NRT for smoking cessation. The aim of this study was to assess understanding and use of NRT and nonpharmacologic treatments among Chinese and Vietnamese American male smokers and their families. In-depth qualitative interviews were conducted with 13 smoker-family pairs, followed by individual interviews with each participant. A total of 39 interviews were conducted in Vietnamese or Chinese, recorded, translated, and transcribed into English for analysis. Four themes were identified: use and understanding of NRT, nonpharmacologic strategies, familial and religious approaches, and willpower. Both smokers and their family members believed strongly in willpower and a sense of personal responsibility as the primary drivers for stopping smoking. Lack of these 2 qualities keeps many Chinese and Vietnamese men from using NRT to quit smoking. Those who do use NRT often use it incorrectly, following their own preferences rather than product instructions. Our findings indicate the importance of culturally appropriate patient education about NRT. It may be necessary to teach smokers and their families at an individual level about NRT as a complementary approach that can strengthen their resolve to quit smoking. At a community level, public health education on the indication and appropriate use of evidence-based smoking cessation resources, such as NRT, would be an important component of effective tobacco control.

The aim of this project was to investigate in members of the Vietnamese community in Melbourne the impact of Mental Health First Aid (MHFA) training on attitudes to people with mental illness and on knowledge about mental disorders. Our hypotheses were that at the end of the training participants would have increased knowledge of mental disorders and their treatments, and decreased negative attitudes towards people with mental disorders. Respondents were 114 participants in two-day MHFA training workshops for the Vietnamese community in Melbourne conducted by two qualified MHFA trainers. Participants completed the research questionnaire prior to the commencement of the training (pre-test) and at its completion (post-test). The questionnaires assessed negative attitudes towards people with mental illness (as described in four vignettes), ability to recognise the mental disorders described in the vignettes, and knowledge about how to assist someone with one of these disorders. Responses to open-ended questions were content analysed and coded. To evaluate the effect of the training, answers to the structured questions and to the coded open-ended questions given at pre- and post-test were compared using McNemar tests for dichotomous values and Wilcoxon tests for other scores. Between pre- and post-test there was significant improvement in recognition of mental disorders; more targeted and appropriate mental health first aid responses, and reduction in inappropriate first aid responses; and negative attitudes to the people described in the vignettes declined significantly on many items of the stigma scale. A two-day, MHFA training course for general members of the Vietnamese community in Melbourne demonstrated significant reductions in stigmatising attitudes, improved knowledge of mental disorders and improved knowledge about appropriate forms of assistance to give to people in the community with mental disorder. There is sufficient evidence to scale up to a population

Study findings suggest that refugees are more vulnerable than the general population to mental disorders from disasters. This pilot study explored the nature of Vietnamese refugees' resilience to a potential natural disaster as a first step toward improving their disaster mental health. Interviews were conducted with 20 ethnic Vietnamese and Montagnard adult refugees using a semistructured interview guide. Factors in resilience at both individual and family levels were examined. Our results indicated that these refugees had positive personalities and strong family cohesion. However, although a majority of the participants had experienced natural disasters, they lacked knowledge and specific strategies to cope with these events. The individual participants and their families lacked sufficient information, financial resources, emergency supplies, or social support for a natural disaster. Enhancing refugees' current strengths in responding to disasters, delivering them tailored emergency training, strengthening relationships between refugee service providers and refugee communities, and advocating for refugees' socioeconomic capacity building should be considered.

Studies of mountain belts worldwide show that along-strike changes are common in their foreland fold-and-thrust belts. These are typically caused by processes related to fault reactivation and/or fault focusing along changes in sedimentary sequences. The study of active orogens, like Taiwan, can also provide insights into how these processes influence transient features such as seismicity and topography. In this paper, we trace regional-scale features from the Eurasian continental margin in the Taiwan Strait into the south central Taiwan fold-and-thrust belt. We then present newly mapped surface geology, P wave velocity maps and sections, seismicity, and topography data to test the hypothesis of whether or not these regional-scale features of the margin are contributing to along-strike changes in structural style, and the distribution of seismicity and topography in this part of the Taiwan fold-and-thrust belt. These data show that the most important along-strike change takes place at the eastward prolongation of the upper part of the margin necking zone, where there is a causal link between fault reactivation, involvement of basement in the thrusting, concentration of seismicity, and the formation of high topography. On the area correlated with the necking zone, the strike-slip reactivation of east northeast striking extensional faults is causing sigmoidal offset of structures and topography along two main zones. Here basement is not involved in the thrusting; there is weak focusing of seismicity and localized development of topography. We also show that there are important differences in structure, seismicity, and topography between the margin shelf and its necking zone.

To describe the use of episiotomy among Vietnamese-born women in Australia, including risk factors for, and pregnancy outcomes associated with, episiotomy. This population-based, retrospective cohort study included data on 598 305 singleton, term (i.e. ≥ 37 weeks' gestation) and vertex-presenting vaginal births between 2001 and 2010. Data were obtained from linked, validated, population-level birth and hospitalization data sets. Contingency tables and multivariate analysis were used to compare risk factors and pregnancy outcomes in women who did or did not have an episiotomy. The episiotomy rate in 12 208 Vietnamese-born women was 29.9%, compared with 15.1% in Australian-born women. Among Vietnamese-born women, those who had an episiotomy were significantly more likely than those who did not to be primiparous, give birth in a private hospital, have induced labour or undergo instrumental delivery. In these women, having an episiotomy was associated with postpartum haemorrhage (adjusted odds ratio, aOR: 1.26; 95% confidence interval, CI: 1.08-1.46) and postnatal hospitalization for more than 4 days (aOR: 1.14; 95% CI: 1.00-1.29). Among multiparous women only, episiotomy was positively associated with a third- or fourth-degree perineal tear (aOR: 2.00; 95% CI: 1.31-3.06); in contrast, among primiparous women the association was negative (aOR: 0.47; 95% CI: 0.37-0.60). Episiotomy was performed in far fewer Vietnamese-born women giving birth in Australia than in Viet Nam, where more than 85% undergo the procedure, and was not associated with adverse outcomes. A lower episiotomy rate should be achievable in Viet Nam.

BACKGROUND/OBJECTIVES This study was conducted to compare the overall changes in dietary intake and metabolic syndrome risk parameters in Vietnamese marriage-based female immigrants over time. SUBJECTS/METHODS The subjects of this study were 581 Vietnamese marriage-based female immigrants, who were recruited from local clinical centers in Korea. Baseline data were collected from 2006-2011 and the follow-up data were collected from 2012-2014. Dietary food intake was assessed by a 1-day 24-hour recall method. RESULTS Compared to the baseline, the mean body weight, body mass index, waist circumference, high density lipoprotein (HDL)-cholesterol, systolic blood pressure and diastolic blood pressure increased while the fasting blood sugar, triglycerides and low density lipoprotein-cholesterol decreased at follow-up. The total consumption of foods such as vegetables/fruits/seaweeds/mushrooms, oil and fat, and eggs decreased during the follow-up period, whereas the consumption of sugars, beverages and meats increased. Partial correlation between the rate of change [(Follow-up - Baseline) / Baseline × 100] in metabolic syndrome risk parameters and food intake after controlling for confounding factors showed that the waist circumference was positively correlated with either the total plant food intake (r = 0.1042, P = 0.0129) or the total food intake (r = 0.0880, P = 0.0359). The plasma levels of total cholesterol (r = -0.1918, P = 0.0289) and HDL-cholesterol (r = -0.1424, P = 0.0007) were negatively correlated with the percentage of total intake from plant food, and HDL-cholesterol levels were positively correlated with the intake of total animal food (r = 0.0980, P = 0.0217). The serum C-reactive protein levels were positively correlated with the total intake of animal food (r = 0.2374, P < 0.0001) or the percentage of total intake from animal food (r = 0.1346, P = 0.0016). CONCLUSIONS These results suggest that the change rate of dietary intake such as total plant food

Hepatitis D virus (HDV) infection is acquired as a co- /superinfection of Hepatitis B virus (HBV) and can modulate the pathophysiology of chronic hepatitis B and related liver diseases including hepatocellular carcinoma. Among the eight distinct HDV genotypes reported, relatively few studies have attempted to investigate the prevalence of HDV mixed genotypes and RNA recombination of HDV. With a recorded prevalence of 10-20% HBV infection in Vietnam, this study investigated the HDV variability, HDV genotypes and HDV recombination among twenty-one HDV isolates in Vietnamese HBsAg-positive patients. HDV subgenomic and full-length genome sequences were obtained using newly established HDV-specific RT-PCR techniques. The nucleotide homology was observed from 74.6% to 99.4% among the investigated full-length genome of the HDV isolates. We observed HDV genotype 1 and HDV genotype 2 in the investigated Vietnamese patients. Although no HDV genotype mixtures were observed, we report here a newly identified recombinant of HDV genotypes (HDV 1 and HDV 2). The identified recombinant HDV isolate C03 revealed sequence homology to both HDV genotype 1 (nt1 to nt907) and HDV genotype 2 (nt908 to nt1675; HDAg coding region) with a breakpoint at nt908. Our findings demonstrate the prevalence of intergenotypic recombination between HDV genotypes 1 and 2 in a Vietnamese HBsAg-positive patient. Extended investigation on the distribution and prevalence of HDV, HDV mixed genotypes and recombinant HDV genotypes in a larger Vietnamese population offers vital insights into understanding of the micro-epidemiology of HDV and subsequent pathophysiology in chronic HBV- /HDV-related liver diseases. © 2014 John Wiley & Sons Ltd.

Homosexuality tolerance among male and female Vietnamese youth: an examination of traditional sexual values, self-esteem, and demographic/contextual characteristics.

Disapproval of homosexuality is the cause of tremendous suffering among sexual minorities. No research has examined determinants of Vietnamese attitudes toward homosexuality. This article examined predictors of such attitudes among Vietnamese youth. Data were from Vietnamese youth aged 15-24 years nationally surveyed in 2009 (Survey Assessment of Vietnamese Youth II). We evaluated structural equation models in which homosexuality tolerance was conceptualized to be influenced by two tiers of predictors: tier 1 (more proximal) including traditional sexual values and self-esteem and tier 2 (more distal) including demographic/contextual variables (urban residence, college education, Internet use, age, and marital status). Female (n = 3,135) and male (n = 3,072) data were analyzed separately. Sexual conservativeness predicted intolerance in both men and women; value of fidelity also predicted intolerance in women. Self-esteem was nonsignificant for women; for men, positive self-perception was nonsignificant, but negative self-perception predicted tolerance. College education, urban residence, and Internet use predicted tolerance, with gender differences. Findings about traditional sexual values, college education, urban residence, and the gender difference in whether self-esteem matters are consistent with the literature. The positive association of Internet use with tolerance was first theorized and tested in this study. The study informs discussions on practice, in terms of tailoring/targeting attitude change interventions to rural versus urban youth and male versus female youth, capitalizing on the Internet to promote respect of sexual diversity, and locating attitudes toward homosexuality within the broader approach to sexuality.

Food and Crime Fiction: Two Complementary Approaches to the Vietnamese Past in Tran-Nhut's Les travers du docteur Porc

Directory of Open Access Journals (Sweden)

Tess Do

2013-07-01

Full Text Available With a series of detective novels set in 17th century Dai-Viet that showcase the traditions, beliefs and customs of an exotic culture, in which the food and food habits of the Vietnamese people play a prominent role, Thanh-Van Tran-Nhut, an engineer-turned-novelist of Vietnamese origins, has carved a niche for herself in the popular crime fiction market in France. This paper focuses on the novel Les Travers du Docteur Porc, in which Doctor Porc, forensic investigator and gourmand extraordinaire, adopts the mantle of chief detective from Tran-Nhut’s usual protagonist, the loyal mandarin Tan. In this movement, we argue, the author has shaped two different but complementary approaches to her birth-country’s turbulent past that coalesce in the gargantuan figure of the (politically unencumbered doctor and connoisseur of Vietnamese cuisine. Whereas the process of ‘solving the crime’ can be read as an attempt to seek answers and restore order in the wake of senseless bloodshed, it is food, we contend, that emerges, not only as a source of pleasure, succour and stability, but as a cultural heritage that war and upheaval failed to destroy.

Abstract Background Nurses in Vietnam, as is typical of many low-income countries, are hampered from impacting health outcomes by low occupational status, overcrowded hospitals and few career development opportunities. In order to understand the current practice environment encountered by nurses in Vietnam in the most realistic way, we listened to the voices of nurses currently performing nursing roles in Vietnam. Purpose The purpose of this study was to explore the emic (insider) perspectives on cultural meaning applied by nurses at a northern Vietnamese women�s hospital to influence professional practice and interpret experience. Design A micro-ethnography approach was used. Methods Seven nurses and one vice-Dean of a school of nursing were interviewed. Data collection consisted of open-ended interviews, participant observation and journal recordings. Spradley�s (1979, 1980) Development Research Sequence was used to guide data collection and analysis. Results/Findings Five themes emerged. These were the big number of patients is a burden for nurses; nurses do not, cannot make their own decisions (but they can and do); my feeling depends on doctor's feeling; nurses learn more from doctor; and just a few nurses can attend the [Vietnamese Nurses Association] meeting. Conclusion The experiences described by the nurses and the vice-Dean of a nursing school reflect the challenges of practicing nursing in one Vietnamese hospital and the resourcefulness of nurses in overcoming those challenges. Recurrent themes highlight the need to better position nurses in Vietnam to advance towards full expression of the professional nursing role.

Every year, the Vietnamese people reportedly burned about 50,000 tons of joss papers, which took the form of not only bank notes, but iPhones, cars, clothes, even housekeepers, in hope of pleasing the dead. The practice was mistakenly attributed to traditional Buddhist teachings but originated in fact from China, which most Vietnamese were not aware of. In other aspects of life, there were many similar examples of Vietnamese so ready and comfortable with adding new norms, values, and beliefs,...

The aim of this study was to analyze the associations between missing teeth, occlusal support, and temporomandibular disorders (TMD) among elderly Vietnamese. The study consisted of 145 TMD and 112 non-TMD (control group) participants aged 65 to 74 years. TMD was evaluated using Diagnostic Criteria for Temporomandibular Disorders (DC/TMD) Axis I. An occlusal unit (OU) was defined as the cusp of a tooth coupled with the fossa of its antagonist tooth. A premolar pair was counted as one OU and a molar pair as two OUs. Dentition was divided into four occlusal support zones (OSZs) based on occluding pairs of posterior teeth by using Eichner classification: Class A had 4 OSZs, Class B had 1 to 3 OSZs or only anterior teeth, and Class C had no OSZ. The TMD group lost significantly more posterior teeth (mean ± SD 5.1 ± 4.7) than the control group (4.0 ± 3.9, P = .033). The mean ± SD OUs of the TMD and control groups were 5.1 ± 4.6 and 6.0 ± 4.3, respectively, which was nonsignificant (NS). The distribution of Class A (40.7%), Class B (40.0%), and Class C (19.3%) among the TMD group was not significantly different from the control group (50.0%, 38.4%, and 11.6%, respectively, NS). The odds of having TMD were positively associated with total unilateral loss of OUs (OR = 3.4, 95% CI = 1.2-9.4, P = .020) and total bilateral loss of OUs (OR = 2.7, 95% CI = 1.2-6.6, P = .027). Total loss of OSZs on one or both sides of the mouth were found to be predictors of TMD among elderly Vietnamese.

Muscle tension dysphonia (MTD) is a hyperfunctional voice disorder commonly seen in professional voice users. To date, published acoustic studies of this disorder have mainly focused on nontonal language speakers, and no publication has documented its impact on lexical tone characteristics. In this study, we examined whether and how this voice disorder affected acoustically and perceptually the characteristics of tones in Vietnamese teachers. Voice data were obtained from 42 Vietnamese female primary school teachers diagnosed with MTD and 30 vocally healthy teachers. Tonal data were analyzed using Computerized Speech Lab (CSL-4300B) and Speech Analyzer. Parameters analyzed included the two most important acoustic cues in Vietnamese tones, that is, tonal fundamental frequency (F(0)) and laryngealization. Tonal F(0) was assessed using a factorial analysis of variance with group and career durations as independent variables. Tonal samples were also perceptually assessed by a panel of native speakers of the same dialect. The results showed that MTD lowered tonal F(0) in high tones and tones with extensive fundamental frequency variation. There was also a significant main effect for career duration; in MTD group, tonal F(0) was lower in teachers with longer career duration. The teachers with MTD showed different patterns of laryngealization compared with the control group. Tone perception was poorer for tones with extensive fundamental frequency variation and without a typical phonation type. The results in this group of teachers supported our hypothesis that MTD impairs lexical tone phonation.

Calculation of freight externality costs for South Africa

Directory of Open Access Journals (Sweden)

Stefaan Swarts

2012-11-01

Full Text Available The purpose of this study is to quantify the marginal external costs associated with freight transport in South Africa. Six cost elements are included as externality cost items, namely, costs related to accidents, emissions, roadway land availability, policing, noise and congestion. Inputs in the calculations were a gravity-oriented freight flow model, a road transport cost model, actual transport costs for other modes, a warehousing cost survey, an inventory delay calculation and various national sources of information such as accident statistics and government budgets. Estimation techniques resulted in advances for externality cost measurement in South Africa. The quantification of the cost elements will be used to update the South African Freight Demand Model. The results show that the cost of transportation would have been 20% more if external factors were taken into account. The marginal rates of externalities can be used to develop scenarios based on alternative choices for South Africa's freight transport infrastructure configuration.

To examine associations between demographic variables, acculturation, and health-related quality of life among Vietnamese immigrant women in transnational marriages in Taiwan. A cross-sectional survey of 203 participants in southern Taiwan. Instruments included a demographic inventory, the Suinn-Lew Asian Self-Identity Acculturation Scale, and the Short Form Health Survey-Version 2. Most participants had low acculturation levels. Length of residency, number of children, marital status, level of education, religion of spouse, and employment status of spouse significantly correlated with level of acculturation, as did mental health, bodily pain, vitality, and social functioning. Programs are needed to encourage social assimilation for Vietnamese immigrant women in Taiwan. Culturally sensitive medical evaluations will ensure early treatment of mental and physical health problems caused by the stress of acculturation. An increased understanding of variables affecting Southeast Asian immigrant women's acculturation process will improve health status.

Evaluate the distribution and the color probability codes of the peripapillary retinal nerve fiber layer (RNFL) and macular ganglion cell-inner plexiform layer (GCIPL) thickness in a healthy Vietnamese population and compare them with the original color-codes provided by the Cirrus spectral domain OCT. Cross-sectional study. We recruited non-glaucomatous Vietnamese subjects and constructed a normative database for peripapillary RNFL and macular GCIPL thickness. The probability color-codes for each decade of age were calculated. We evaluated the agreement with Kappa coefficient (κ) between OCT color probability codes with Cirrus built-in original normative database and the Vietnamese normative database. 149 eyes of 149 subjects were included. The mean age of enrollees was 60.77 (±11.09) years, with a mean spherical equivalent of +0.65 (±1.58) D and mean axial length of 23.4 (±0.87) mm. Average RNFL thickness was 97.86 (±9.19) microns and average macular GCIPL was 82.49 (±6.09) microns. Agreement between original and adjusted normative database for RNFL was fair for average and inferior quadrant (κ=0.25 and 0.2, respectively); and good for other quadrants (range: κ=0.63-0.73). For macular GCIPL κ agreement ranged between 0.39 and 0.69. After adjusting with the normative Vietnamese database, the percent of yellow and red color-codes increased significantly for peripapillary RNFL thickness. Vietnamese population has a thicker RNFL in comparison with Cirrus normative database. This leads to a poor color-code agreement in average and inferior quadrant between the original and adjusted database. These findings should encourage to create a peripapillary RNFL normative database for each ethnicity.

We examine the impacts of trauma exposures and family stressors associated with the Vietnam War on musculoskeletal health and posttraumatic stress disorder (PTSD) outcomes in elderly Vietnamese who were widely impacted by the war as young adults. Noting that wars' impacts extend beyond male veterans in most survivor populations, we give attention to male and female war survivors placed in a variety of roles vis-a-vis the war. Utilizing data from the 2010 Vietnam Health and Aging Pilot Study (N = 405), we use logistic and Poisson regression models to estimate the effect of wartime trauma exposures and family stressors on disabling arthritis and PTSD symptoms in male and female northern Vietnamese adults aged 55 and older. The odds of experiencing recent PTSD symptoms are greater in respondents who report involvement in killing/causing severe injury and who observed war atrocities. In women, PTSD is positively correlated with war era child death and spousal separation. Arthritis also exhibits a significant, positive association with killing/causing severe injury. Our study provides insights into the burden of conflict upon health among populations of the global south that survived war and are now entering older adulthood. The pattern of results, indicating greatest suffering among those who inflicted or failed to prevent bodily harm or loss of life, is consistent with the concept of moral injury. © The Author 2016.

Factors influencing motivation and job satisfaction among supervisors of community health workers in marginalized communities in South Africa.

Science.gov (United States)

Akintola, Olagoke; Chikoko, Gamuchirai

2016-09-06

Management and supervision of community health workers are factors that are critical to the success of community health worker programmes. Yet few studies have explored the perspectives of supervisors in these programmes. This study explored factors influencing motivations of supervisors in community health worker programmes. We conducted qualitative interviews with 26 programme staff providing supervision to community health workers in eight community-based organizations in marginalized communities in the greater Durban area of South Africa from July 2010 to September 2011. Findings show that all the supervisors had previous experience working in the health or social services sectors and most started out as unpaid community health workers. Most of the participants were poor women from marginalized communities. Supervisors' activities include the management and supply of material resources, mentoring and training of community health workers, record keeping and report writing. Supervisors were motivated by intrinsic factors like making a difference and community appreciation and non-monetary incentives such as promotion to supervisory positions; acquisition of management skills; participation in capacity building and the development of programmes; and support for educational advancement like salary, bonuses and medical benefits. Hygiene factors that serve to prevent dissatisfaction are salaries and financial, medical and educational benefits attached to the supervisory position. Demotivating factors identified are patients' non-adherence to health advice and alienation from decision-making. Dissatisfiers include working in crime-prevalent communities, remuneration for community health workers (CHWs), problems with material and logistical resources, job insecurity, work-related stressors and navigating the interface between CHWs and management. While participants were dissatisfied with their low remuneration, they were not demotivated but continued to be motivated

Racism, Schooling, and the Streets: A Critical Analysis of Vietnamese American Youth Gang Formation in Southern California

Directory of Open Access Journals (Sweden)

Kevin D. Lam

2012-01-01

Full Text Available This paper is an analysis of the relationship between educational experiences, street life, and gang formation for Vietnamese American youth gang members in Southern California. I use critical narrative methodology to center the life and experiences of a Los Angeles area gang member. His narrative substantiates how racism in schools and on the streets works together to impact and inform gang formation. Schools were sites of inter-ethnic conflict and racialized tension, and streets were spaces for contentious interactions with the police. In addition, I place the Vietnamese American youth gang phenomenon in larger historical and political contexts such as California’s anti-youth legislation, representations of Asian American youth, and U.S. geo-politics and imperialism—factors that have serious material and ideological implications and consequences.

The objectives of this study were to develop a food-frequency questionnaire (FFQ) for Vietnamese female immigrants in Korea and to evaluate the validity of the FFQ. A total of 80 food items were selected in developing the FFQ according to consumption frequency, the contribution of energy and other nutrients, and the cooking methods based on one-day 24 hour recall (24HR) from 918 Vietnamese female immigrants between November 2006 and November 2007. The FFQ was validated by comparison with 24HR of 425 Vietnamese female immigrants between November 2008 and August 2009. The absolute nutrient intake calculated from the FFQ was higher than that estimated by 24HR for most nutrients. The correlation coefficients between 24HR and FFQ ranged from 0.10 (vitamin C) - 0.36 (energy) for crude intake, 0.05 (vitamin E) - 0.32 (calcium) for per 1000 kcal, and 0.08 (zinc) - 0.34 (calcium) for energy-adjusted, respectively. More than 70% of subjects were classified into the same or adjacent agreement groups for nutrients other than fiber, sodium, vitamin A, vitamin C, and vitamin E, while less than 10% of subjects were classified into complete disagreement groups. We conclude that the FFQ appears to be an acceptable tool for estimating nutrient intake and dietary patterns of Vietnamese female immigrants in Korea. Future studies to validate the FFQ using various biomarkers or other dietary assessment methods are needed.

Exploring Vietnamese co-authorship patterns in social sciences with basic network measures of 2008-2017 Scopus data [version 1; referees: 2 approved

2017-08-01

Full Text Available Background: Collaboration is a common occurrence among Vietnamese scientists; however, insights into Vietnamese scientific collaborations have been scarce. On the other hand, the application of social network analysis in studying science collaboration has gained much attention all over the world. The technique could be employed to explore Vietnam’s scientific community. Methods: This paper employs network theory to explore characteristics of a network of 412 Vietnamese social scientists whose papers can be found indexed in the Scopus database. Two basic network measures, density and clustering coefficient, were taken, and the entire network was studied in comparison with two of its largest components. Results: The networks connections are very sparse, with a density of only 0.47%, while the clustering coefficient is very high (58.64%. This suggests an inefficient dissemination of information, knowledge, and expertise in the network. Secondly, the disparity in levels of connection among individuals indicates that the network would easily fall apart if a few highly-connected nodes are removed. Finally, the two largest components of the network were found to differ from the entire networks in terms of measures and were both led by the most productive and well-connected researchers. Conclusions: High clustering and low density seems to be tied to inefficient dissemination of expertise among Vietnamese social scientists, and consequently low scientific output. Also low in robustness, the network shows the potential of an intellectual elite composed of well-connected, productive, and socially significant individuals.

Seismic analysis of clinoform depositional sequences and shelf-margin trajectories in Lower Cretaceous (Albian) strata, Alaska North Slope

Science.gov (United States)

Houseknecht, D.W.; Bird, K.J.; Schenk, C.J.

2009-01-01

Lower Cretaceous strata beneath the Alaska North Slope include clinoform depositional sequences that filled the western Colville foreland basin and overstepped the Beaufort rift shoulder. Analysis of Albian clinoform sequences with two-dimensional (2D) seismic data resulted in the recognition of seismic facies inferred to represent lowstand, transgressive and highstand systems tracts. These are stacked to produce shelf-margin trajectories that appear in low-resolution seismic data to alternate between aggradational and progradational. Higher-resolution seismic data reveal shelf-margin trajectories that are more complex, particularly in net-aggradational areas, where three patterns commonly are observed: (1) a negative (downward) step across the sequence boundary followed by mostly aggradation in the lowstand systems tract (LST), (2) a positive (upward) step across the sequence boundary followed by mostly progradation in the LST and (3) an upward backstep across a mass-failure d??collement. These different shelf-margin trajectories are interpreted as (1) fall of relative sea level below the shelf edge, (2) fall of relative sea level to above the shelf edge and (3) mass-failure removal of shelf-margin sediment. Lowstand shelf margins mapped using these criteria are oriented north-south in the foreland basin, indicating longitudinal filling from west to east. The shelf margins turn westward in the north, where the clinoform depositional system overstepped the rift shoulder, and turn eastward in the south, suggesting progradation of depositional systems from the ancestral Brooks Range into the foredeep. Lowstand shelf-margin orientations are consistently perpendicular to clinoform-foreset-dip directions. Although the Albian clinoform sequences of the Alaska North Slope are generally similar in stratal geometry to clinoform sequences elsewhere, they are significantly thicker. Clinoform-sequence thickness ranges from 600-1000 m in the north to 1700-2000 m in the south

2015-07-01

Full Text Available Background The purpose of this study was to analyse similarities and differences in the motivational value system of Vietnamese parents and adolescents, in the context of Schwartz’s value theory. Also, the transmission of values between two generations was studied. Participants and procedure The study was performed in three different cities of Vietnam – Hanoi, Hue and Ho Chi Minh City – on adolescents, their fathers and mothers (N = 2226. The hierarchy of values was measured with a Vietnamese version of the Portrait Value Questionnaire (PVQ-40. Additionally, expectations of parents toward children and preferences of children were measured with a list of 28 features and attitudes prepared for the study. Results The results show that both parents and their adolescent children highly respect universalism, conformity, and benevolence in contrast to power and stimulation, which is still typical for a collectivistic culture. The differences arise in higher-order values: while parents value conservatism (security, conformity and tradition, their children prefer more openness to change (self-direction and hedonism values, which is typical for a more individualistic culture. The results also reveal that parents in Vietnam expect and transfer to children some attitudes and features such as studiousness, filial piety and diligence, but not riskiness, desire or humour. Although adolescents are aware of their parents’ expectations, they do not fully accept them. Conclusions The results provide hints for parents to plan their strategy on appropriate education of their children, in the current context of global integration and cultural changes.

Effect of gamma-irradiation on the fatty acid composition of salted, semi-dried Vietnamese scad and Bombay duck

1994-01-01

Effect of gamma irradiation on the lipid and fatty acid composition of semi-dried Bombay duck (Harpodon nehcreus) and Vietnamese scad (Alepes mate) was studied. In both these dried fishes, c16:0 aand c18:1 were the predominant fatty acids and the fishes contained ignificant quantities of the n-3 polyunsaturated fatty acids (PUFAs), C20:5 and C22:6. Irradiation at a dose of 3 kGy, did not cause any alterations in the total lipid content and he overall lipid class profile in these fishes. However, in the Vietnamese scad, C18:3, C20:4 and C22:6 were significantly decreased in the irradiated samples. In spite of this decrease the irradiated semi-dried scad retained 82% of the initial amount of n-3 PUFAs

Tectonic implications of Mesozoic magmatism to initiation of Cenozoic basin development within the passive South China Sea margin

Mai, Hue Anh; Chan, Yu Lu; Yeh, Meng Wan; Lee, Tung Yi

2018-04-01

The South China Sea (SCS) is one of the classical example of a non-volcanic passive margin situated within three tectonic plates of the Eurasian, Indo-Australian and Philippine Sea plate. The development of SCS resulted from interaction of various types of plate boundaries, and complex tectonic assemblage of micro blocks and accretionary prisms. Numerous models were proposed for the formation of SCS, yet none can fully satisfy different aspects of tectonic forces. Temporal and geographical reconstruction of Cretaceous and Cenozoic magmatism with the isochrones of major basins was conducted. Our reconstruction indicated the SE margin of Asia had gone through two crustal thinning events. The sites for rifting development are controlled by localized thermal weakening of magmatism. NW-SE extension setting during Late Cretaceous revealed by magmatism distribution and sedimentary basins allow us to allocate the retreated subduction of Pacific plate to the cause of first crustal thinning event. A magmatic gap between 75 and 65 Ma prior to the initiation of first basin rifting suggested a significant modification of geodynamic setting occurred. The Tainan basin, Pearl River Mouth basin, and Liyue basins started to develop since 65 Ma where the youngest Late Cretaceous magmatism concentrated. Sporadic bimodal volcanism between 65 and 40 Ma indicates further continental extension prior to the opening of SCS. The E-W extension of Malay basin and West Natuna began since late Eocene followed by N-S rifting of SCS as Neotethys subducted. The SCS ridge developed between Pearl River Mouth basin and Liyue basin where 40 Ma volcanic activities concentrated. The interaction of two continental stretching events by Pacific followed by Neotethys subduction with localized magmatic thermal weakening is the cause for the non-volcanic nature of SCS.

The genetics of osteogenesis imperfecta (OI) have not been studied in a Vietnamese population before. We performed mutational analysis of the COL1A1 and COL1A2 genes in 91 unrelated OI patients of Vietnamese origin. We then systematically characterized the mutation profiles of these two genes which are most commonly related to OI. Genomic DNA was extracted from EDTA-preserved blood according to standard high-salt extraction methods. Sequence analysis and pathogenic variant identification was performed with Mutation Surveyor DNA variant analysis software. Prediction of the pathogenicity of mutations was conducted using Alamut Visual software. The presence of variants was checked against Dalgleish's osteogenesis imperfecta mutation database. The sample consisted of 91 unrelated osteogenesis imperfecta patients. We identified 54 patients with COL1A1/2 pathogenic variants; 33 with COL1A1 and 21 with COL1A2. Two patients had multiple pathogenic variants. Seventeen novel COL1A1 and 10 novel COL1A2 variants were identified. The majority of identified COL1A1/2 pathogenic variants occurred in a glycine substitution (36/56, 64.3 %), usually serine (23/36, 63.9 %). We found two pathogenic variants of the COL1A1 gene c.2461G > A (p.Gly821Ser) in four unrelated patients and one, c.2005G > A (p.Ala669Thr), in two unrelated patients. Our data showed a lower number of collagen OI pathogenic variants in Vietnamese patients compared to reported rates for Asian populations. The OI mutational profile of the Vietnamese population is unique and related to the presence of a high number of recessive mutations in non-collagenous OI genes. Further analysis of OI patients negative for collagen mutations, is required.

Objectives. We conducted a cluster randomized controlled study of a lay health worker (LHW) intervention to increase colorectal cancer (CRC) screening rates among Vietnamese Americans, who typically have lower rates than do non-Hispanic Whites. Methods. We randomized 64 LHWs to 2 arms. Each LHW recruited 10 male or female participants who had never had CRC screening (fecal occult blood test, sigmoidoscopy, or colonoscopy). Intervention LHWs led 2 educational sessions on CRC screening. Control LHWs led 2 sessions on healthy eating and physical activity. The main outcome was self-reported receipt of any CRC screening at 6 months after the intervention. We conducted the study from 2008 to 2013 in Santa Clara County, California. Results. A greater proportion of intervention participants (56%) than control participants (19%) reported receiving CRC screening (P Vietnamese Americans. Randomized controlled trials are needed to test the effectiveness of LHW outreach for other populations and other health outcomes. PMID:26270306

2015-12-29

The goal of this project was to explore family communication dynamics and their implications for smoking cessation. We conducted 39 in-depth dyadic and individual qualitative interviews with 13 immigrant smoker-family member pairs of Vietnamese (n = 9 dyads, 18 individuals) and Chinese (n = 4 dyads, 8 individuals) descent, including seven current and six former smokers and 13 family members. All 13 dyadic and 26 individual interviews were analyzed using a collaborative crystallization process as well as grounded theory methods. We identified three interrelated pathways by which tobacco use in immigrant Vietnamese and Chinese families impacts family processes and communication dynamics. Using a two-dimensional model, we illustrate how the shared consequences of these pathways can contribute to a dynamic of avoidance and noncommunication, resulting in individual family members "suffering in silence" and ultimately smoking being reinforced. We discuss the implications of these findings for development of smoking cessation interventions. © The Author(s) 2015.

Full Text Available Despite the emergence of social media in many aspects of Vietnamese lives, including marketing and promotional activities, Vietnamese organizations have used little social media in their crisis communication efforts. The organizations are hesitant to adopt social media in crisis communication and prefer to use traditional media because of its controllability and professionalism. However, with the increasing number of organizational crises that started on social media in the past years, it is arguably that Vietnamese stakeholders use social media as one of their main communication channels during crises. Should the organizations use social media in response? Through a series of interviews to PR practitioners and stakeholders in Vietnam, this research aims to find out the similarities and gaps in the perception of social media use for crisis communication between these two groups, and to guide a crisis communication practice that is appreciated by stakeholders.   Bahasa Indonesia Abstrak: Meskipun munculnya media sosial dalam banyak aspek kehidupan Vietnam, termasuk kegiatan pemasaran dan promosi, organisasi Vietnam telah menggunakan sedikit media sosial dalam upaya komunikasi krisis mereka.

Previous studies have reported that the nutritional status of Vietnamese female marriage immigrants in Korea is inadequate. And the mediation of acculturation stress can contribute to problems in their eating practices and dietary intakes. This study examines an association between psychological distress and inadequate dietary intake in Vietnamese female marriage immigrants living in Korea. A cross-sectional study analyzed baseline data (n=570) from the Cohort of Intermarried Women in Korea. Daily nutrient intakes were compared according to the quartiles of distress scores assessed by the Psychological Well-Being Index-Short Form. One-way analysis of variance and chi(2) tests were used to compare eating practices and nutrient intake across quartiles of psychological distress. Subjects in the highest stress scores were more likely to skip breakfast and to change their dietary habits after living in Korea than those in groups with low stress scores. Analyses of the subjects' Mini Dietary Assessments revealed that those with the highest stress scores were less likely to consume milk or dairy products, eat regular meals, or have balanced diets than those with the lowest stress scores. Nutrient intakes were found to be inadequate in the subjects, and those with the highest stress scores showed lower consumptions of energy, carbohydrate, protein, fat, calcium, zinc, thiamin, riboflavin, and folate compared to those with the lowest scores. The prevalence of underweight (body mass index [calculated as kg/m(2)] Korea was negatively associated with dietary intake. These findings can assist dietetics practitioners working with minority immigrants because such information is important in designing appropriate strategies for dietary counseling. A follow-up study should address the underlying mechanisms of the observed diet-distress association in Vietnamese marriage immigrant women in Korea, as well as other various ethnic minority immigrants in Korea.

The Continental Margin of East Asia: a collage of multiple plates formed by convergence and extension from multiple directions

Science.gov (United States)

Mao, J.; Wang, T.; Ludington, S.; Qiu, Z.; Li, Z.

East Asia is one of the most complex regions in the world. Its margin was divided into 4 parts: Northeast Asia, North China, South China and Southeast Asia. During the Phanerozoic, continental plates of East Asia have interacted successively with a) the Paleo Tethyan Ocean, b) the Tethyan and Paleo Pacific Oceans and c) the Pacific and Indian. In the Early Mesozoic, the Indosinian orogeny is characterized by the convergence and extension within multiple continental plates, whereas the Late Mesozoic Yanshanian orogeny is characterized by both convergence and compression due to oceanic subduction and by widespread extension. We propose this combination as "East Asia Continental Margin type." Except in Northeast Asia, where Jurassic and Cretaeous accretionary complexes are common, most magmatic rocks are the result of reworking of ancient margins of small continental plates; and oceanic island arc basalts and continental margin arc andesites are largely absent. Because South China is adjacent to the western margin of the Pacific Plate, some effects of its westward subduction must be unavoidable, but juvenile arc-related crust has not been identified. The East Asian Continental Margin is characterized by magmatic rocks that are the result of post-convergent tectonics, which differs markedly from the active continental margins of both South and North America. In summary, the chief characteristics of the East Asian Continental Margin are: 1) In Mesozoic, the periphery of multiple blocks experienced magmatism caused by lithospheric delamination and thinning in response to extension punctuated by shorter periods of convergence. 2) The main mechanism of magma generation was the partial melting of crustal rocks, due to underplating by upwelling mafic magma associated with the collapse of orogenic belts and both extension and compression between small continental blocks. 3) During orogeny, mostly high Sr/Y arc-related granitoids formed, whereas during post-orogenic times, A

Immigrants in the U.S. may encounter challenges of acculturation, including dietary habits, as they adapt to new surroundings. We examined Vietnamese and Hispanic immigrant children's American food consumption patterns in a convenience sample of 63 Vietnamese and Hispanic children in grades four to six who were attending an after school program. Children indicated the number of times they consumed each of 54 different American foods in the past week using a food frequency questionnaire. We ranked each food according to frequency of consumption, compared the intake of foods to the USDA Healthy Eating Pattern, and performed dietary pattern analysis. Since the data were not normally distributed we used two nonparametric tests to evaluate statistical significance: the Kruskal-Wallis tested for significant gender and ethnicity differences and the Wilcoxon signed-rank test evaluated the food consumption of children compared with the USDA recommended amounts. We found that among USDA categories, discretionary food was most commonly consumed, followed by fruit. The sample as a whole ate significantly less than the recommended amount of grains, protein foods, and dairy, but met the recommended amount of fruit. Boys ate significantly more grains, proteins, and fruits than did girls. Dietary pattern analysis showed a very high sweet snack consumption among all children, while boys ate more fast food and fruit than girls. Foods most commonly consumed were cereal, apples, oranges, and yogurt. Ethnicity differences in food selection were not significant. The high intake of discretionary/snack foods and fruit, with low intake of grains, vegetables, protein, and dairy in our sample suggests Vietnamese and Hispanic immigrant children may benefit from programs to improve diet quality.

Objective:To screen Vietnamese medicinal plants for xanthine oxidase (XO) inhibitory activity and to isolate XO inhibitor(s) from the most active plant.Methods: The plants materials were extracted by methanol. The active plant materials were fractionated using different organic solvents, includingn-hexane, ethyl acetate, andn-butanol. Bioassay-guided fractionation and column chromatography were used to isolate compounds. The compounds structures were elucidated by analysis of spectroscopic data, including IR, MS, and NMR. Results:Three hundreds and eleven methanol extracts (CME) belonging to 301 Vietnamese herbs were screened for XO inhibitory activity. Among these plants, 57 extracts displayed XO inhibitory activity at 100 μg/mL with inhibition rates of over 50%. The extracts of Archidendron clypearia,Smilax poilanei,Linociera ramiflora and Passiflora foetida exhibited the greatest potency with IC50 values below 30 μg/mL. Chemical study performed on the extract ofArchidendron clypearia resulted in the isolation of six compounds, including 1-octacosanol, docosenoic acid, daucosterol, methyl gallate, quercitrin and (?)-7-O-galloyltricetiflavan. The compound (?)-7-O-galloyltricetiflavan showed the most potent XO inhibitory activity with an IC50 value of 25.5 μmol/L.Conclusions:From this investigation, four Vietnamese medicinal plants were identified to have XO inhibitory effects with IC50 values of the methanol extracts below 30 μg/mL. Compound (?)-7-O-galloyltricetiflavan was identified as an XO inhibitor from Archidendron clypearia with IC50 value of 25.5 μmol/L.

Passive continental margins are geo-archives that store information from the interplay of endogenous and exogenous forces related to continental rifting, post-breakup history, and climate changes. The recent South Atlantic passive continental margins (SAPCMs) in Brazil, Namibia, and South Africa are partly high-elevated margins ( 2000 m a.s.l.), and the recent N-S-trending SAPCM in Argentina and Uruguay is of low elevation. In Argentina, an exception in elevation is arising from the higher topography (> 1000 m a.s.l.) of the two NW-SE-trending mountain ranges Sierras Septentrionales and Sierras Australes. Precambrian metamorphic and intrusive rocks, and siliciclastic rocks of Ordovician to Permian age represent the geological evolution of both areas. The Sierras Australes have been deformed and metamorphosed (incipient - greenschist) during the Gondwanides Orogeny. The low-temperature thermochronological (LTT) data (history of the Gondwanides and the Mesozoic and Cenozoic South Atlantic geological evolution. Upper Carboniferous zircon (U-Th/He)-ages (ZHe) indicate the earliest cooling below 180 °C/1 Ma. Most of the ZHe-ages are of Upper Triassic to Jurassic age. The apatite fission-track ages (AFT) of Sierras Septentrionales and the eastern part of Sierras Australes indicate the South Atlantic rifting and, thereafter. AFT-ages of Middle to Upper Triassic on the western side of the Sierras Australes are in contrast, indicating a Triassic exhumation caused by the eastward thrusting along the Sauce Grande wrench. The corresponding t-T models report a complex subsidence and exhumation history with variable rates since the Ordovician. Based on the LTT-data and the numerical modelling we assume that the NW-SE-trending mountain ranges received their geographic NW-SE orientation during the syn- to post-orogenic history of the Gondwanides.

Objective: To investigate the prevalence of HIV infection/STD and related factors in Vietnamese female sex workers (FSWs). Methods: Consecutive cross-sectional surveys were conducted in June 2014, December 2014, May 2015 and November 2015 in Hekou, a county bordering Vietnam in Yunnan province. Convenience sampling were adopted to select 1 058 Vietnamese FSWs aged>16 years. Questionnaire interview were used to collect the information about their demographics, sexual behaviors and drug use. Serum and urine samples were collected for HIV infection/STD detection and drug use test. Trend χ (2) test was applied for HIV infection/STD and drug use trend analysis. Multivariate logistic regression model was used to identify the related factors. Results: The consecutive cross sectional surveys indicated that the prevalence of HIV infection in Vietnamese FSWs were 3.20 % (7/219), 2.04 % (5/245), 1.89 % (5/265) and 1.82 % (6/329) respectively; the HSV-2 positive rates were 57.08 % (125/219), 58.37 % (143/245), 38.11 % (101/265) and 51.06 % (168/329) respectively. In addition, the prevalence of syphilis were 0.91 % , 1.51 % , 0.75 % and 1.22 % respectively. HSV-2 infection prevalence showed a downward trend ( χ (2)=4.823, P =0.028). By logistic regression analysis, the related factors for HIV infection in Vietnamese FSWs were being amphetamine type stimulants (ATS) positive ( OR =10.18, 95 %CI : 4.33-23.92) and being HSV-2 positive ( OR =2.89, 95 %CI : 1.09-7.88); Age ( OR =1.88, 95 %CI : 1.32-2.61), no-paid sexual partner ( OR =1.59, 95 %CI : 1.26-2.01) and being ATS positive ( OR =2.48, 95 %CI : 1.10-5.57) were related factors for HSV-2 infection. Conclusions: Compared with the results of previous studies, the HIV infection prevalence declined in Vietnamese FSWs, but the HSV-2 infection prevalence was still high. The association between ATS use and HIV infection/STD suggested the necessity of strengthening AIDS intervention in Vietnamese FSWs, including the control of new

The association of waterpipe tobacco (WPT) smoking with gastric cancer (GC) risk was suggested. A hospital-based case-control study was conducted to examine the association of WPT with GC risk among Vietnamese men, in Hanoi city, during the period of 2003-2011. Newly-diagnosed GC cases (n = 454) and control patients (n = 628) were matched by age (+/- 5 years) and the year of hospitalization. Information on smoking and alcohol drinking habits and diet including salty food intake and fruits/vegetables consumption were obtained by the interview. Maximum likelihood estimates of odds ratios (ORs) and corresponding 95% confidence intervals (Cis) were obtained using conditional logistic regression models. The group with the highest consumption of citrus fruits showed a significantly low GC risk (OR = 0.6, 95%CI = 0.4-0.8, P for trend = 0.002). However, there was no association of raw vegetable consumption with GC risk. Referring to never smokers, GC risk was significantly higher in current WPT smokers (OR = 1.8, 95%CI = 1.3-2.4), and it was more evident in exclusively WPT smokers (OR = 2.7, 95%CI = 1.2-6.5). GC risk tended to be higher with daily frequency and longer duration of WPT smoking but these trends were not statistically significant (P for trend: 0.144 and 0.154, respectively). GC risk of those who started smoking WPT before the age of 25 was also significantly high (OR = 3.7, 95%CI = 1.2-11.3). Neither cigarette smoking nor alcohol drinking was related to GC risk. The present findings revealed that WPT smoking was positively associated with GC risk in Vietnamese men.

Extensive management of field margins enhances their potential for off-site soil erosion mitigation.

Soil erosion is a widespread problem in agricultural landscapes, particularly in regions with strong rainfall events. Vegetated field margins can mitigate negative impacts of soil erosion off-site by trapping eroded material. Here we analyse how local management affects the trapping capacity of field margins in a monsoon region of South Korea, contrasting intensively and extensively managed field margins on both steep and shallow slopes. Prior to the beginning of monsoon season, we equipped a total of 12 sites representing three replicates for each of four different types of field margins ("intensive managed flat", "intensive managed steep", "extensive managed flat" and "extensive managed steep") with Astroturf mats. The mats (n = 15/site) were placed before, within and after the field margin. Sediment was collected after each rain event until the end of the monsoon season. The effect of management and slope on sediment trapping was analysed using linear mixed effects models, using as response variable either the sediment collected within the field margin or the difference in sediment collected after and before the field margin. There was no difference in the amount of sediment reaching the different field margin types. In contrast, extensively managed field margins showed a large reduction in collected sediment before and after the field margins. This effect was pronounced in steep field margins, and increased with the size of rainfall events. We conclude that a field margin management promoting a dense vegetation cover is a key to mitigating negative off-site effects of soil erosion in monsoon regions, particularly in field margins with steep slopes.

Origin of a crustal splay fault and its relation to the seismogenic zone and underplating at the erosional north Ecuador-south Colombia oceanic margin

Splay faults within accretionary complexes are commonly associated with the updip limit of the seismogenic zone. Prestack depth migration of a multichannel seismic line across the north Ecuador-south Colombia oceanic margin images a crustal splay fault that correlates with the seaward limit of the rupture zone of the 1958 (Mw 7.7) tsunamogenic subduction earthquake. The splay fault separates 5-6.6 km/s velocity, inner wedge basement rocks, which belong to the accreted Gorgona oceanic terrane, from 4 to 5 km/s velocity outer wedge rocks. The outer wedge is dominated by basal tectonic erosion. Despite a 3-km-thick trench fill, subduction of 2-km-high seamount prevented tectonic accretion and promotes basal tectonic erosion. The low-velocity and poorly reflective subduction channel that underlies the outer wedge is associated with the aseismic, décollement thrust. Subduction channel fluids are expected to migrate upward along splay faults and alter outer wedge rocks. Conversely, duplexes are interpreted to form from and above subducting sediment, at ˜14- to 15-km depths between the overlapping seismogenic part of the splay fault and the underlying aseismic décollement. Coeval basal erosion of the outer wedge and underplating beneath the apex of inner wedge control the margin mass budget, which comes out negative. Intraoceanic basement fossil listric normal faults and a rift zone inverted in a flower structure reflect the evolution of the Gorgona terrane from Cretaceous extension to likely Eocene oblique compression. The splay faults could have resulted from tectonic inversion of listric normal faults, thus showing how inherited structures may promote fluid flow across margin basement and control seismogenesis.

Knowledge about the sources, transport pathways and behavior of terrestrial organic carbon in continental margins adjoining to large rivers has improved in recent decades, but uncertainties and complications still exist with human-influenced coastal regions in densely populated wet tropics and subtropics. In these regions, the monsoon and other episodic weather events exert strong climatic control on mineral and particulate organic matter delivery to the marginal seas. Here we investigate elemental (TOC, TN and bromine-Br) and stable carbon isotopic (δ13C) compositions of organic matter (OM) in surface sediments and short cores collected from active (SW Taiwan) and passive margin (East China Sea) settings to understand the sources of OM that buried in these settings. We used sedimentary bromine to total organic carbon (Br/TOC) ratios to apportion terrigenous from marine organic matter, and find that Br/TOC may serve as an additional, reliable proxy for sedimentary provenance in both settings. Variations in Br/TOC are consistent with other provenance indicators in responding to short-lived terrigenous inputs. Because diagenetic alteration of Br is insignificant on shorter time scales, applying Br/TOC ratios as a proxy to identify organic matter source along with carbon isotope mixing models may provide additional constraints on the quantity and transformation of terrigenous organics in continental margins. We apply this combination of approaches to land-derived organic matter in different depositional environments of East Asian marginal seas.

While health information websites may have previously been the core source of information about health-related conditions on the Internet, social networking sites are increasingly replacing those websites as a source of health-related information. The increasingly popularity of social networking sites among the general population has consequential impact on health policies as well as health-related interventions. To date, there remains a paucity of research conducted in developing countries like Vietnam looking at the influence of social networking sites. Our goal is to establish the baseline use of Facebook among Vietnamese youths and establish their perception of the reliability and usefulness of health-related information that they previously encountered while using the social networking site. An online cross-sectional study was conducted from August 2015 to October 2015. Respondent-driven sampling (RDS) technique was used in the recruitment of participants. Sociodemographic, health status, behaviors, Facebook use and belief of information on Facebook, and interpersonal influence of social network sites were collected via an online structured questionnaire. Among 1080 participants, 72.87% (787/1080) reported being interested in health information on Facebook, and 50.74% (548/1080) and 17.50% (189/1080) perceived the information to be reliable and useful, respectively. A total of 10.93% (118/1080) of the participants also reported that they would follow the health advice they obtained from Facebook. Of significance, 7.13% (77/1080) of the participants also reported peer influences on their behavior. Factors that mediate Vietnamese perceptions of the information online include gender, level of perceived stress, age, educational level, and interpersonal influences from Facebook. Our study is perhaps one of the first conducted in Vietnam that looks at the relationship between health information on Facebook and factors that might influence young Vietnamese

The aim of this study was to investigate whether the artificial aging by thermal cycling had influenced the marginal adaptation of class V restorations with/without chlorhexidine application in the bond process. Twelve intact human third molars were used. Class V cavity preparations were performed on the buccal surface and the teeth received 35% phosphoric acid-etching procedure (Ultradent Products Inc., South Jordan, Utah, USA). Subsequently, the samples were divided in two groups: Untreated acid-etched dentin and chlorhexidine application as an adjunct in the bond process. The adhesive Single Bond 2 (3M ESPE, St. Paul, MN, USA) was used after 2% chlorhexidine application, and the restorations were performed with Filtek™ Z350 XT (3M ESPE) composite resin. The specimens were submitted to artificial aging by thermal cycling with 3,000 cycles. Analyzes were performed on scanning electron microscopy using replicas of marginal adaptation in percentage of continuous margin before and after the artificial aging. The data were analyzed by paired test and the results showed statistically significant differences in the percentage of continuous margin with/without chlorhexidine treatment before and after thermal cycling. This study concluded that the artificial aging by thermal cycling influenced the marginal adaptation of mixed class V composite restorations.

Medical abortion: understanding perspectives of rural and marginalized women from rural South India.

To understand how rural and other groups of marginalized women define safe abortion; their perspectives and concerns regarding medical abortion (MA); and what factors affect their access to safe abortion. Focus group discussions were held with various groups of rural and marginalized women in Tamil Nadu to understand their perspectives and concerns on abortion, especially MA. Nearly a decade after mifepristone was approved for abortion in India, most study participants had never heard of MA. When they learned of the method, most preferred it over other methods of abortion. The women also had questions and concerns about the method and recommendations on how services should be provided. Their definition of a "safe abortion" included criteria beyond medical safety. They placed a high priority on "social safety," including confidentiality and privacy. In their view, factors affecting access to safe abortion and choice of provider included cost, assurance of secrecy, promptness of service provision, and absence of provider gatekeeping and provider-imposed conditions for receiving services. Women's preference for MA shows the potential of this technology to address the problem of unsafe abortion in India. Women need better access to information and services to realize this potential, however. Women's preferences regarding information dissemination and service provision need to be taken into account if policies and programs are to be truly responsive to the needs of marginalized women.

The aim of this in vitro study was to investigate the effect of Shoulder versus Chamfer margin design on the marginal adaptation of zirconia (Zr) copings. 40 extracted molar teeth were mounted in resin and prepared for zirconia crowns with two margin preparation designs (20=Shoulder and 20=Chamfer). The copings were manufactured by Cercon® (DeguDent GmbH, Germany) using the CAD/CAM system for each tooth. They were tried on each tooth, cemented, thermocycled, re-embedded in resin and were subsequently cross sectioned centrally into two equal mesial and distal halves. They were examined under electron microscope at 200 X magnification and the measurements were recorded at 5 predetermined points in micrometers (µm). The o verall mean marginal gap for the two groups was found to be 206.98+42.78µm with Shoulder margin design (Marginal Gap=199.50+40.72µm) having better adaptation compared to Chamfer (Marginal Gap=214.46+44.85µm). The independent-samples t-test showed a statistically non-significant difference (p=.113) between the means of marginal gap for Shoulder and Chamfer margin designs and the measurements were recorded at 5 predetermined points for the two groups. The Chamfer margin design appeared to offer the same adaptation results as the Shoulder margin design.

This study employed the 2009 California Health Interview Survey to examine the association of self-rated heath status and lifestyle behavior variables such as smoking at least 100 cigarettes or more in an entire lifetime, alcohol consumption, and physical activity level among foreign-born Chinese, Korean, and Vietnamese Americans aged 18 and older. The total study sample consisted of 3,023 foreign-born adult Chinese (n = 812), Korean (n = 857), and Vietnamese (n = 1,354) Americans. Logistic regression via Stata 12 was employed. Odds ratios (OR) along with confidence intervals (CI) were reported in the results. Results revealed that smoking at least 100 cigarettes or more in an entire lifetime had a negative association with good health status (OR = 0.74, 95 % CI = 0.59, 0.94), while alcohol consumption had a positive association with good health status (OR = 1.20, 95 % CI = 1.00, 1.44). Moderate physical activity (OR = 1.26, 95 % CI = 1.05, 1.50) and vigorous physical activity (OR = 1.68, 95 % CI = 1.31, 2.15) had a similar positive association with good self-rated health status. The results also revealed that the predicted probability of self-rated health status based on ethnicity and lifestyle variables was more favorable for foreign-born Chinese Americans than their Korean and Vietnamese American counterparts. This study's results corroborated the findings reported in previous research on the association of lifestyle behaviors and health status. Regardless of racial or ethnic backgrounds, good lifestyles have an important role in the prevention of poor health status. However, health education and lifestyle intervention programs should take cultural differences among racial and ethnic populations into consideration.

Understanding factors that influence physical activity levels of adolescents can assist the design of more effective interventions. Social support is a consistent correlate of youth physical activity but few studies have examined this in different cultural settings. Male adolescents (n=180, age=13.58+/-0.97 years) from a metropolitan single sex private school participated in this study. Habitual physical activity was estimated using the 3-day physical activity recall (3dPAR), and aspects of social support to be physically active using a specifically designed questionnaire. Comparisons were made between Anglo-Australians (n=118), whose parents were both born in Australia, and Vietnamese-Australians (n=62), whose parents were both born in Vietnam. There was a trend towards higher physical activity among Anglo-Australians, particularly on weekends. Anglo-Australians reported significantly more parental and peer support across most items pertaining to these constructs. Among the whole sample, social support variables explained 5-12% of the total explained variance in physical activity, with items pertaining to father and best friend support emerging as the strongest and most consistent predictors in multiple regression models. Among Anglo-Australians, the prediction models were relatively weak, explaining 0-9% of the total explained variance in physical activity. Prediction models for physical activity among Vietnamese-Australians were much stronger, explaining 11-32% of the total explained variance, with father's support variables contributing consistently to these models. The strong paternal influence on physical activity among Vietnamese-Australians needs to be confirmed in more diverse population groups, but results from this study suggest that interventions promoting physical activity among adolescent boys need to take into account cultural background as a moderator of widely reported social influences.

This study analyzed the dietary pattern of Southeast Asian workers (Vietnamese, Thais, Cambodians and Myanmar) living in South Korea in order to recognize the dietary changes after they moved to South Korea. Questionnaires were completed by 251 Southeast Asian workers living in South Korea. Using a self-administered questionnaire, we assessed the diets before and after living in the hometown and in South Korea. Significant changes observed in the Southeast Asian workers were decreased in consumption frequency of fresh fruits, cooked vegetables, rice noodles, green tea and glutinous rice, and increase in consumption of Kimchi, seaweed, milk, coffee and pizza. These changes were attributed to rapid dietary acculturation. The frequencies of eating homemade food were significantly decreased after they came to Korea except for Thais. Thais showed the highest frequencies of eating homemade food daily among others. 28.2% of respondents said their health condition had deteriorated after living in South Korea due to difficulties to adapt Korean food, increased frequencies of eating instant food, and lacking exercises. By providing understanding of the dietary patterns of Southeast Asian workers, these results can be used for preliminary data to develop a program for their Korean food adaptation.

Geometry of basins can indicate their tectonic origin whether they are small or large. The basins of Bohai Gulf, South China Sea, East China Sea, Japan Sea, Andaman Sea, Okhotsk Sea and Bering Sea have typical geometry of dextral pull-apart. The Java, Makassar, Celebes and Sulu Seas basins together with grabens in Borneo also comprise a local dextral, transform-margin type basin system similar to the central and southern parts of the Shanxi Basin in geometry. The overall configuration of the Philippine Sea resembles a typical sinistral transpressional "pop-up" structure. These marginal basins except the Philippine Sea basin generally have similar (or compatible) rift history in the Cenozoic, but there do be some differences in the rifting history between major basins or their sub-basins due to local differences in tectonic settings. Rifting kinematics of each of these marginal basins can be explained by dextral pull-apart or transtension. These marginal basins except the Philippine Sea basin constitute a gigantic linked, dextral pull-apart basin system.

The impact of minimum wage adjustments on Vietnamese wage inequality

DEFF Research Database (Denmark)

Hansen, Henrik; Rand, John; Torm, Nina

Using Vietnamese Labour Force Survey data we analyse the impact of minimum wage changes on wage inequality. Minimum wages serve to reduce local wage inequality in the formal sectors by decreasing the gap between the median wages and the lower tail of the local wage distributions. In contrast, local...... wage inequality is increased in the informal sectors. Overall, the minimum wages decrease national wage inequality. Our estimates indicate a decrease in the wage distribution Gini coefficient of about 2 percentage points and an increase in the 10/50 wage ratio of 5-7 percentage points caused...... by the adjustment of the minimum wages from 2011to 2012 that levelled the minimum wage across economic sectors....

Marginal abatement cost curves for policy recommendation – A method for energy system analysis

International Nuclear Information System (INIS)

Tomaschek, Jan

2015-01-01

The transport sector is seen as one of the key factors for driving future energy consumption and greenhouse gas (GHG) emissions. In order to rank possible measures marginal abatement cost curves have become a tool to graphically represent the relationship between abatement costs and emission reduction. This paper demonstrates how to derive marginal abatement cost curves for well-to-wheel GHG emissions of the transport sector considering the full energy provision chain and the interlinkages and interdependencies within the energy system. Presented marginal abatement cost curves visualize substitution effects between measures for different marginal mitigation costs. The analysis makes use of an application of the energy system model generator TIMES for South Africa (TIMES-GEECO). For the example of Gauteng province, this study exemplary shows that the transport sector is not the first sector to address for cost-efficient reduction of GHG emissions. However, the analysis also demonstrates that several options are available to mitigate transport related GHG emissions at comparable low marginal abatement costs. This methodology can be transferred to other economic sectors as well as to other regions in the world to derive cost-efficient GHG reduction strategies

Social influences on physical activity in Anglo-Australian and Vietnamese-Australian adolescent females in a single sex school.

Wilson, Andrew N; Dollman, James

2009-01-01

Social support is a consistent correlate of youth physical activity (PA) but few studies have examined this in cultural sub-groups. Female adolescents (n=113; 13.9+/-0.6years) from a metropolitan single sex private school participated in this study. PA was estimated using the 3 Day Physical Activity Recall (3dPAR), and aspects of social support using a specifically designed questionnaire. Anglo-Australians (n=74), whose parents were both born in Australia, were compared with Vietnamese-Australians (n=39), whose parents were both born in Vietnam. There were non-significant trends towards higher engagement in all measures of PA among Anglo-Australians. Anglo-Australians perceived higher levels of social support to be physically active. In the whole sample and in cultural sub-groups, support by mothers was a consistent predictor of PA. Among Vietnamese-Australians, activities shared with the mother predicted moderate to vigorous PA. Interventions targeting PA among adolescent females should consider interactions of social support and cultural background.

Deep seismic data represent a key to understand the geometry and mechanism of continental rifting. The passive continental margin of NW-Africa is one of the oldest on earth, formed during the Upper Triassic-Lower Liassic rifting of the central Atlantic Ocean over 200 Ma. We present new and existing wide-angle and reflection seismic data from four study regions along the margin located in the south offshore DAKHLA, on the central continental margin offshore Safi, in the northern Moroccan salt basin, and in the Gulf of Cadiz. The thickness of unthinned continental crust decreases from 36 km in the North to about 27 km in the South. Crustal thinning takes place over a region of 150 km in the north and only 70 km in the south. The North Moroccan Basin is underlain by highly thinned continental crust of only 6-8 km thickness. The ocean-continent transition zone shows a variable width between 40 and 70 km and is characterized by seismic velocities in between those of typical oceanic and thinned continental crust. The neighbouring oceanic crust is characterized by a thickness of 7-8 km along the complete margin. Relatively high velocities of up to 7.5 km/s have been imaged between magnetic anomalies S1 and M25, and are probably related to changes in the spreading velocities at the time of the Kimmeridgian/Tithonian plate reorganization. Volcanic activity seems to be mostly confined to the region next to the Canary Islands, and is thus not related to the initial opening of the ocean, which was associated to only weak volcanism. Comparison with the conjugate margin off Nova Scotia shows comparable continental crustal structures, but 2-3 km thinner oceanic crust on the American side than on the African margin.

A bathymetric terrain model of the Atlantic margin covering almost 725,000 square kilometers of seafloor from the New England Seamounts in the north to the Blake Basin in the south is compiled from existing multibeam bathymetric data for marine geological investigations. Although other terrain models of the same area are extant, they are produced from either satellite-derived bathymetry at coarse resolution (ETOPO1), or use older bathymetric data collected by using a combination of single beam and multibeam sonars (Coastal Relief Model). The new multibeam data used to produce this terrain model have been edited by using hydrographic data processing software to maximize the quality, usability, and cartographic presentation of the combined 100-meter resolution grid. The final grid provides the largest high-resolution, seamless terrain model of the Atlantic margin..

2015-07-01

Bone mineral density (BMD) is under strong genetic regulation, but it is not clear which genes are involved in the regulation, particularly in Asian populations. This study sought to determine the association between 29 genes discovered by Caucasian-based genome-wide association studies and BMD in a Vietnamese population. The study involved 564 Vietnamese men and women aged 18 years and over (average age: 47 years) who were randomly sampled from the Ho Chi Minh City. BMD at the femoral neck, lumbar spine, total hip and whole body was measured by DXA (Hologic QDR4500, Bedford, MA, USA). Thirty-two single nucleotide polymorphisms (SNPs) in 29 genes were genotyped using Sequenom MassARRAY technology. The magnitude of association between SNPs and BMD was analyzed by the linear regression model. The Bayesian model average method was used to identify SNPs that are independently associated with BMD. The distribution of genotypes of all, but two, SNPs was consistent with the Hardy-Weinberg equilibrium law. After adjusting for age, gender and weight, 3 SNPs were associated with BMD: rs2016266 (SP7 gene), rs7543680 (ZBTB40 gene), and rs1373004 (MBL2/DKK1 gene). Among the three genetic variants, the SNP rs2016266 had the strongest association, with each minor allele being associated with ~0.02 g/cm(2) increase in BMD at the femoral neck and whole body. Each of these genetic variant explained about 0.2 to 1.1% variance of BMD. All other SNPs were not significantly associated with BMD. These results suggest that genetic variants in the SP7, ZBTB40 and MBL2/DKK1 genes are associated with BMD in the Vietnamese population, and that the effect of these genes on BMD is likely to be modest.

2017-03-01

Providing holistic care is acknowledged as central to providing quality care for patients with cancer, but providing competent nursing care consistent with these approaches remains a challenge for nurses in Vietnam. Obstacles for Vietnamese oncology nurses include their low status, the limited scope of nursing practice, work overload in a hierarchical system, and cultural beliefs that view death and dying as taboo. Additional research to support oncology nurses in Vietnam must acknowledge the merits of improving nursing education as an important strategy for enhancing nursing autonomy, quality of care, and outcomes for the increasing number of patients with cancer in low- and middle-income countries.

To screen Vietnamese medicinal plants for xanthine oxidase (XO) inhibitory activity and to isolate XO inhibitor(s) from the most active plant. The plants materials were extracted by methanol. The active plant materials were fractionated using different organic solvents, including n-hexane, ethyl acetate, and n-butanol. Bioassay-guided fractionation and column chromatography were used to isolate compounds. The compounds structures were elucidated by analysis of spectroscopic data, including IR, MS, and NMR. Three hundreds and eleven methanol extracts (CME) belonging to 301 Vietnamese herbs were screened for XO inhibitory activity. Among these plants, 57 extracts displayed XO inhibitory activity at 100 μg/mL with inhibition rates of over 50%. The extracts of Archidendron clypearia (A. clypearia), Smilax poilanei, Linociera ramiflora and Passiflora foetida exhibited the greatest potency with IC 50 values below 30 μg/mL. Chemical study performed on the extract of A. clypearia resulted in the isolation of six compounds, including 1-octacosanol, docosenoic acid, daucosterol, methyl gallate, quercitrin and (-)-7-O-galloyltricetiflavan. The compound (-)-7-O-galloyltricetiflavan showed the most potent XO inhibitory activity with an IC 50 value of 25.5 μmol/L. From this investigation, four Vietnamese medicinal plants were identified to have XO inhibitory effects with IC 50 values of the methanol extracts below 30 μg/mL. Compound (-)-7-O- galloyltricetiflavan was identified as an XO inhibitor from A. clypearia with IC 50 value of 25.5 μmol/L. Copyright © 2017 Hainan Medical University.

We developed the first Vietnamese Internalized Homophobia (IH) scale for use with Vietnamese sexual minority women (SMW). Drawing from existing IH scales in the international literature and based on prior qualitative research about SMW in the Viet Nam context, the scale covers two domains: self-stigma (negative attitudes toward oneself as a sexual minority person) and sexual prejudice (negative attitudes toward homosexuality/same-sex relations in general). Scale items, including items borrowed from existing scales and items based on local expressions, were reviewed and confirmed by members of the target population. Quantitative evaluation used data from an anonymous web-based survey of Vietnamese SMW, including those who identified as lesbian (n = 1187), or as bisexual (n = 641) and those who were unsure about their sexual identity (n = 353). The scale was found to consist of two highly correlated factors reflecting self-stigma (not normal/wholesome and self-reproach and wishing away same-sex sexuality) and one factor reflecting sexual prejudice, and to have excellent internal consistency. Construct validity was evidenced by subscale associations with a wide range of hypothesized correlates, including perceived sexual stigma, outness, social support, connection to other SMW, relationship quality, psychological well-being, anticipation of heterosexual marriage, and endorsement of same-sex marriage legalization. Self-stigma was more strongly associated with psychosocial correlates, and sexual prejudice was more associated with endorsement of legal same-sex marriage. The variations in these associations across the hypothesized correlates and across sexual identity groups were consistent with the minority stress model and the IH literature, and exhibited context-specific features, which are discussed.

People are exposed to methylmercury (MeHg) mainly through fish consumption, which is increasing in Vietnam. However, little information is available on estimating the health risk of MeHg exposure through fish consumption in Vietnam. The present study examined the association between mercury (Hg) levels in hair and selenium (Se) levels in toenails of 196 Vietnamese people and their fish consumption, using a dietary questionnaire to obtain information pertinent for assessing health risk owing to MeHg exposure. The geometric mean of Hg levels in the hair of males and females was 617 ng/g and 575 ng/g, respectively. We found that Hg levels in the hair of 98% of the Vietnamese study subjects were lower than the provisional tolerable weekly intake for MeHg (1.6 µg Hg/kg body weight; which is equivalent to a hair Hg concentration of approximately 2,300 ng/g, with an uncertainty factor of 6.4). There were significant differences in the age-adjusted geometric mean of Hg levels found in hair from females related to their frequency of freshwater fish consumption. The levels of Hg in hair and Se in toenails increased with an increased frequency of marine fish consumption, and both showed a significant positive correlation in subjects who consumed marine fish ≥ once/week. This is the first cross-sectional study to investigate the association between hair Hg levels and fish consumption in Vietnam. These findings provide valuable information for future assessments of the health risk of MeHg exposure through fish consumption in Vietnam.

Full Text Available This article explores marginality theory as it was first proposed in  the social sciences, that is related to persons caught between two competing cultures (Park; Stonequist, and, then, as it was developed in sociology as related to the poor (Germani and in anthropology as it was related to involuntary marginality and voluntary marginality (Victor Turner. It then examines a (normative scheme' in antiquity that creates involuntary marginality at the macrosocial level, namely, Lenski's social stratification model in an agrarian society, and indicates how Matthean language might fit with a sample inventory  of socioreligious roles. Next, it examines some (normative schemes' in  antiquity for voluntary margi-nality at the microsocial level, namely, groups, and examines how the Matthean gospel would fit based on indications of factions and leaders. The article ,shows that the author of the Gospel of Matthew has an ideology of (voluntary marginality', but his gospel includes some hope for (involuntary  marginals' in  the  real world, though it is somewhat tempered. It also suggests that the writer of the Gospel is a (marginal man', especially in the sense defined by the early theorists (Park; Stone-quist.

Attitudes toward hepatitis B virus among Vietnamese, Chinese and Korean Americans in the Houston area, Texas.

Hwang, Jessica P; Roundtree, Aimee K; Suarez-Almazor, Maria E

2012-10-01

We explored attitudes about prevention, screening and treatment of hepatitis B virus (HBV) infection in Chinese, Korean and Vietnamese communities. We use qualitative methods in 12 focus groups (n = 113) of adults who self-reported their ethnicity to be Chinese, Korean, or Vietnamese. We use grounded theory (i.e., consensus-building between co-coders about recurring, emerging themes) for analysis. Diet, nutrition, fatigue and stress were misidentified as HBV causes. Improving hygiene, diet, exercise, and holistic methods were misidentified as viable HBV prevention methods. Common screening problems included not affording test and not understanding test results. Participants shared reasons for using complementary and alternative medicine--when Western medicine fails or becomes unaffordable. Participants sought information from medical providers and fellow community members, but also from the internet. Many of the attitudes and opinions that emerged may deter participation in HBV screening, prevention and treatment, insofar as community members may factor them into healthcare decision-making, choose alternative but ineffective methods of prevention and treatment, and undervalue the benefits of screening. More patient education in both traditional and new media is necessary for clarifying transmission, screening and treatment misunderstandings.

Eliciting Patients’ Health Concerns in Consulting Rooms and Wards in Vietnamese Public Hospitals

Directory of Open Access Journals (Sweden)

Huong Thi Linh Nguyen

2018-03-01

Full Text Available This article examines the doctor’s elicitation of the patient’s presenting health concern in two clinical settings in the Vietnamese public hospital system: the consulting room and the ward. The data were taken from 66 audio-recorded consultations. Our analysis shows that the elicitors used by the doctor in the consulting room often communicate a weak epistemic stance towards the patient’s health issue, while those used in the ward tend to signal a strong epistemic stance. In addition, this contrast between the elicitors employed in the consulting room and the ward is evident in our data regardless of whether the consultation is a first visit or a same follow-up (in which the doctor is the same one that treated the patient on their last visit, though the contrast is less clear for different follow-ups (in which the doctor has not treated the patient before. An additional finding is that the clinical setting has some bearing on the use of inappropriate elicitation formats (in which the doctor opens the visit with an elicitor which is more appropriate for another type of visit. The precise way in which each of the consulting room and the ward operates is, of course, a feature of the Vietnamese public hospital system itself. Hence, the overall contrast between the elicitors and elicitation formats used in these two settings illustrates how, on a more general level, the institutional context can have an impact on doctor-patient communication.

2016-09-01

Full Text Available The study examines technical efficiency of Foreign Direct Investment (FDI firms in the Vietnamese manufacturing sector by applying stochastic production frontier model and making use of cross-sectional data in the period 2009-2013. The average level of technical efficiency of FDI firms is about 60% and it is higher than that of domestic firms (including private firms and state-owned firms. In addition, the study also analyses correlation between technical efficiency of FDI firms and other factors. It finds that there are positive correlations between FDI technical efficiency and net revenue per labour, firm’s age or export activities in 2013. However, the study is unable to find evidence of a relationship between FDI technical efficiency and infrastructure or firm’s investment activities.

Genesis of giant promontories during two-stage continental breakup and implications for post-Rodinia circum-Arctic margins (Invited)

Science.gov (United States)

Bradley, D. C.

2013-12-01

Giant promontories are a seldom-noted feature of the present-day population of passive margins. A number of them formed during the breakup of Pangea: the South Tasman Rise and Naturaliste Plateau off Australia, the Grand Banks and Florida off North America, the Falkland Plateau off South America, and the Horn of Africa. Giant promontories protrude hundreds of kms seaward from a corner of the continent and are not to be confused with the low-amplitude irregularies that occur at intervals along most passive margins. Giant promontories that might have formed during the breakup of the earlier supercontinents, Rodinia and Nuna, have not been recognized. Properties of the modern examples suggest some identifying criteria. They are cored by continental crust that was created or last reworked during the previous collisional cycle. Judging from the examples listed, the early histories of the two flanks of a promontory will differ because separate continents or microcontinents drift away in different directions at different times. For example, the eastern flank of the >500-km-long South Tasman Rise formed when the Lord Howe Rise separated from Australia at ca. 85 Ma, whereas the western flank formed when Antarctica moved past at ca. 65-33 Ma. (Age spans of various passive margins quoted herein are from Bradley, 2008, Earth Sci. Rev. 91:1-26.) During ocean closure (typically, arc-passive margin collision), a promontory may be exposed to earlier and more intense tectonism than elsewhere along the margin. Unique events are also possible. For example, the tip of Florida experienced a glancing collision with Cuba during the Paleogene, an event that was not felt elsewhere along the Gulf or Atlantic margins of the southeastern U.S. Giant promontories are unlikely to have deep lithospheric keels and may be prone to being dislodged and rotated during collision. Thus, what starts as a promontory may end up as a microcontinent in an orogen. The case for giant promontories in the circum

Full Text Available This article examines changing governing practices in the context of the Sino-Vietnamese border in the Guangxi Autonomous Region of China. The groups inhabiting the mountainous ranges of this ethnically diverse part of Southeast Asia evaded the reach of the state until the 1970s, when China and Vietnam started tightening control over the land border after the border war. With an increasingly rigid and clearly delimited Sino-Vietnamese borderland, binary forms of classification began to replace earlier fluid identifications, and the room for diverse social and cultural expressions became restricted. It is within this context that the ethnic marriage practices straddling the borders of China and its southern neighboring states discussed in this article took place. Cross-border ethnic Yao marriages have gone from customary to illegal in recent years as a result of China’s strict population control, its changing demography, and the accelerated shortage of manual labor in its border area. Border politics have permeated the private sphere, transforming common ethnic marriage partners into illegal migrants. Although ethnic marriage partners are relegated to an illegal status, they are indispensible in the local labor market and moral economy as mothers, caretakers, translators, guides, and manual workers. This article argues that, despite being antithetical to the bordering logic of state sovereignty, they are important agents who depend on and capitalize on the border economy.

The objective of this study was to examine how Vietnamese family caregivers (FCGs) perceive, manage and experience end-of-life care-giving for seriously ill family members. Using an instrumental case study design, this longitudinal qualitative research employed the use of cultural brokers/language interpreters to help ensure that the research was conducted in a culturally-appropriate manner. Participants (n = 18) discussed their experiences of care-giving within the context of a traditional cultural framework, which was found to influence their motivations and approaches to care-giving, as well as their propensities towards the use of various supports and services. The study was carried out in southern Ontario, Canada, and participants were providing home-based care-giving in the community. Data were collected throughout 2010 and 2011. The ways in which care-giving was perceived and expressed are reflected in three themes: (i) Natural: identity and care work; (ii) Intentional: whole-person care; and (iii) Intensive: standards, struggle and the context of care. This research confirms the need for culturally-appropriate services and supports while illustrating that Vietnamese FCGs not only value, but are also likely to use healthcare and social services if they are language-accessible, built on trust and demonstrate respect for their values as individuals, regardless of culture. © 2014 The Authors.

Submerged or drowned reefs constitute an important geological record of sea level variations, forming the substrate for the colonization of modern benthic mesophotic communities. Although mapping mesophotic reefs has increased in the last years, their spatial distribution is poorly known and the worldwide occurrence of this reef habitat maybe underestimated. The importance in recognizing the distribution of mesophotic reefs is that they can act as a refuge for corals during unsuitable environmental conditions and a repository for shallow water corals. Here we present the result of several acoustic surveys that mapped and discovered new mesophotic reefs along the Eastern and Equatorial Brazilian Continental Margin. Seabed mapping was carried out using multibeam and side scan sonars. Ground truthing was obtained using drop camera or scuba diving. Mesophotic reefs were mapped in water depths varying from 30 to 100m and under distinct oceanographic conditions, especially in terms of river load input and shelf width. Reefs showed distinct morphologies, from low relief banks and paleovalleys to shelf edge ridges. Extensive occurrence of low relief banks were mapped along the most important coralline complex province in the South Atlantic, the Abrolhos Shelf. These 30 to 40m deep banks, have no more than 3 meters in height and may represent fringing reefs formed during sea level stabilization. Paleovalleys mapped along the eastern margin showed the occurrence of coralgal ledges along the channel margins. Paleovalleys are usually deeper than 45m and are associated with outer shelf rhodolith beds. Shelf edge ridges (80 to 120m deep) were mapped along both margins and are related to red algal encrusting irregular surfaces that have more than 3m in height, forming a rigid substrate for coral growth. Along the Equatorial Margin, off the Amazon mouth, shelf edge patch reefs and rhodolith beds forming encrusting surfaces and shelf edge ridges were mapped in water depths greater

In order to quantify the influence of NW striking potentially seismogenic normal faults over the longitudinal variation of the Central Chile Coastal margin uplift, we measured Quaternary marine terraces, which represent the tectonic uplift of the coastal margin. Movement in margin oblique normal faults occurs by co-seismic extension of major subduction earthquakes and has occurred in the Pichilemu fault, generating a 7.0 Mw earthquake after the 2010 8.8 Mw Maule earthquake.The coastal area between 32° and 34° S was selected due to the presence of a well-preserved sequence of 2 to 5 Quaternary marine terraces. In particular, the margin oblique normal NW-trending, SW-dipping Laguna Verde fault, south of Valparaiso (33° S) puts in contact contrasting morphologies: to the south, a flat coast with wide marine terraces is carved in both, Jurassic plutonic rocks and Neogene semi-consolidated marine sediments; to the north, a steeper scarp with narrower marine terraces, over 120 m above the corresponding ones in the southern coast, is carved in Jurassic plutonic rocks.We have collected over 6 months microseimic data, providing information on seismic activity and underground geometry of the Laguna Verde fault. We collected ca. 100 systematic measurements of fringes at the base of paleo coastal scarps through field mapping and a 5 m digital elevation model. These fringes mark the maximum sea level during the terrace's carving.The heights of these fringes range between 0 and 250 masl. We estimate a 0.7 mm/yr slip rate for the Laguna Verde fault based on the height difference between corresponding terraces north- and southward, with an average uplift rate of 0.3 mm/yr for the whole area.NW striking normal faults, besides representing a potential seismic threat to the near population on one of the most densely populated areas of Chile, heavily controls the spatial variation of the coastal margin uplift. In Laguna Verde, the uplift rate differs more than three times northward

Rifted continental margins and basins are mainly formed by the lithospheric extension. Thined lithosphere of passive continental margins results in decompression melt of magma and created oceanic crust and thined ocean-continent transition (OCT) zone. Two refraction profiles used ocean bottom seismometers deployed in the broad continental shelf and three multi-channel seismic reflection lines in the northern South China Sea, acquired by the ship "Shiyan 2" of the South China Sea Institute of Oceanology, Chinese Academy of Sciences in 2010, are processed and interpreted in this study. Seismic reflection lines cut through the Dongsha rise, Zhu-1 and Zhu-2 depression within a Tertiary basin, Pear River Mouth basin (called as Zhujiangkou basin). These tectonic features are clear imaged in the seismic reflection records. Numerous normal faults, cutted through the basement and related to the stretch of the northern South China Sea margin, are imaged and interpreted. Reflection characteristics of the ocean-continent transition (OCT) zone are summaried and outlined. The COT zone is mainly divided into the northern syn-rift subsidence zone, central volcano or buried volcano uplift zone and tilt faulted block near the South Chia Sea basin. Compared to the previous seismic reflection data and refraction velocity models, the segmentation range of the OCT zone is outlined, from width of about 225 km in the northeastern South China Sea , of 160 km in the central to of 110 km in the north-central South China Sea. Based on the epicenter distribution of sporadic and large than 6 magnitude earthquakes, it suggests the OCT zone in the northern South China Sea at present is still an active seismic zone.

We have studied the petrography, geochemistry, and detrital zircon U-Pb ages of sandstones from shallow-marine forearc sediments, accretionary complexes (ACs), and metamorphosed accretionary complexes (Meta-ACs) within the Kurosegawa belt of Southwest Japan. Those rocks formed in a forearc region of a Permian island arc associated with subduction of the Panthalassa oceanic crust along the eastern margin of the South China block (Yangtze block). The provenance of the shallow-marine sediments was dominated by basaltic to andesitic volcanic rocks and minor granitic rocks during the late Middle to Late Permian. The ACs were derived from felsic to andesitic volcanic rocks during the Late Permian. The provenance of Meta-ACs was dominated by andesitic volcanic rocks in the Middle Permian. The provenance, source rock compositions, and zircon age distribution for the forearc sediments, ACs and Meta-ACs have allowed us to reconstruct the geological history of the Permian arc system of the Kurosegawa belt. During the Middle Permian, the ACs were accreted along the eastern margin of the South China block. The Middle Permian arc was an immature oceanic island arc consisting of andesitic volcanic rocks. During the Late Permian, the ACs formed in a mature arc, producing voluminous felsic to andesitic volcanic rocks. A forearc basin developed during the late Middle to Late Permian. Subsequently, the Middle Permian ACs and part of the Late Permian AC underwent low-grade metamorphism in the Late to Early Jurassic, presenting the Meta-ACs.

Asymmetric rifting, breakup and magmatism across conjugate margin pairs: insights from Newfoundland to Ireland

Science.gov (United States)

Peace, Alexander L.; Welford, J. Kim; Foulger, Gillian R.; McCaffrey, Ken J. W.

2017-04-01

Continental extension, subsequent rifting and eventual breakup result in the development of passive margins with transitional crust between extended continental crust and newly created oceanic crust. Globally, passive margins are typically classified as either magma-rich or magma-poor. Despite this simple classification, magma-poor margins like the West Orphan Basin, offshore Newfoundland, do exhibit some evidence of localized magmatism, as magmatism to some extent invariably accompanies all continental breakup. For example, on the Newfoundland margin, a small volcanic province has been interpreted near the termination of the Charlie Gibbs Fracture Zone, whereas on the conjugate Irish margin within the Rockall Basin, magmatism appears to be more widespread and has been documented both in the north and in the south. The broader region over which volcanism has been identified on the Irish margin is suggestive of magmatic asymmetry across this conjugate margin pair and this may have direct implications for the mechanisms governing the nature of rifting and breakup. Possible causes of the magmatic asymmetry include asymmetric rifting (simple shear), post-breakup thermal anomalies in the mantle, or pre-existing compositional zones in the crust that predispose one of the margins to more melting than its conjugate. A greater understanding of the mechanisms leading to conjugate margin asymmetry will enhance our fundamental understanding of rifting processes and will also reduce hydrocarbon exploration risk by better characterizing the structural and thermal evolution of hydrocarbon bearing basins on magma-poor margins where evidence of localized magmatism exists. Here, the latest results of a conjugate margin study of the Newfoundland-Ireland pair utilizing seismic interpretation integrated with other geological and geophysical datasets are presented. Our analysis has begun to reveal the nature and timing of rift-related magmatism and the degree to which magmatic asymmetry

Experience curve analysis on South Korean nuclear technology and comparative analysis with South Korean renewable technologies

Kim, Dong Wook; Chang, Hyun Joon

Increasing awareness on environmental damage and climate change has induced many nations to engage in green growth. South Korea, as one of the largest consumers of energy, is no exception and has shown its determination to pursue green growth in the future. In order to do so, South Korea plans to substitute fossil fuel with alternative sources in electricity generation. However, the key constraint to green growth is the high cost faced by renewable electricity generation. Fortunately, nuclear energy can serve as an economic alternative to fossil fuel. To achieve CO 2 emission reduction and faster economic growth, it is wise to analyze prospects of alternatives using experience curve framework. The results and industry background are consistent for nuclear technology, and the results suggest that nuclear should serve as the main substitute. Consideration of policy risk inherent in renewable also strengthens the argument. Renewable technologies, on the other hand, showed overstated learning capacity that is partially inconsistent with technological background. Nevertheless, the renewable (photovoltaic and fuel cell) should help nuclear marginally in substituting fossil fuel in South Korea's Electricity Generation. - Highlights: ► Progress ratios of renewable energy show great prospect. ► The policy risk is inherent in renewable and may overestimate its prospect. ► Nuclear sources are economic and less affected by policy risk. ► Fuel cell and photovoltaic should help nuclear marginally in green growth.

Marginalization is often presented as the strategy associated with the worst adjustment for immigrants. This study identifies a critical variable that buffers marginal immigrants from the negative effects of marginalization on adjustment: The need for uniqueness. In three studies, we surveyed immigrants recruited on university campuses (n = 119, n = 116) and in the field (n = 61). Among marginal immigrants, a higher need for uniqueness predicted higher self-esteem (Study 1), affect (Study 2), and life satisfaction (Study 3), and marginally higher happiness (Study 2) and self-esteem (Study 3). No relationship between the need for uniqueness and adjustment was found among non-marginal immigrants. The adaptive value of the need for uniqueness for marginal immigrants is discussed. © 2015 The British Psychological Society.

2013-11-30

Using a nationally representative sample of 1280 Asian Americans, we examined the extent to which major depressive disorder (MDD) onset differs by ethnicity and its associated factors for each of the three ethnic groups: Vietnamese, Filipino, and Chinese. We employed the Kaplan-Meier method to estimate the survival and hazard functions for MDD onset by ethnicity, and cox proportional hazards models to identify socio-demographic and immigration-related factors associated with MDD onset. Approximately 7% of the entire sample had experienced MDD onset in their lifetime. Filipino immigrants showed the highest survival function, followed by Vietnamese immigrants over time. Those who were never-married or divorced were more likely to experience MDD onset when compared to their married or cohabiting counterparts. Those who immigrated at a younger age were more likely to experience MDD onset than were those who immigrated at an older age. However, there were ethnic variations in terms of the risk factors that were associated with MDD onset across these three ethnic groups. Findings from this study signal the importance of understanding the differing experiences of MDD onset by ethnicity. Copyright © 2013 Elsevier Ireland Ltd. All rights reserved.

Factors controlling sedimentation in the Toruń-Eberswalde ice-marginal valley during the Pomeranian phase of the Weichselian glaciation: an overview

Directory of Open Access Journals (Sweden)

Pisarska-Jamroży Małgorzata

2015-03-01

Full Text Available During the Pleistocene the Scandinavian ice sheet drained huge quantities of sediment-laden meltwaters. These meltwaters supplied ice-marginal valleys that formed parallel to the front of the ice sheet. Not without significance was the supply of ice-marginal valleys from extraglacial rivers in the south. Moreover, periglacial conditions during and after sedimentation in ice-marginal valleys, the morphology of valley bedrocks, and erosion of older sediments played important roles in the depositional scenarios, and in the mineralogical composition of the sediments. The mechanisms that controlled the supply and deposition in ice-marginal valleys were analysed on the basis of a Pleistocene ice-marginal valley that was supplied by northern and southern source areas in the immediate vicinity. Investigations were conducted in one of the largest ice-marginal valleys of the Polish-German lowlands, i.e., the Toruń-Eberswalde ice-marginal valley, in sandurs (Drawa and Gwda supplied sediments and waters from the north into this valley, and on extraglacial river terraces (pre-Noteć and pre-Warta rivers, formed simultaneously with the sandurs and ice-marginal valley (Pomeranian phase of Weichselian glaciation supplied sediments and waters from the south into this valley. A much debated question is how similar, or different, depositional processes and sediments were that contributed to the formation of the Toruń-Eberswalde ice-marginal valley, and whether or not it is possible to differentiate mostly rapidly aggraded sandur sediments from ice-marginal valley sediments. Another question addresses the contribution of extraglacial feeding of the Toruń-Eberswalde ice-marginal valley. These matters were addressed by a wide range of analyses: sediment texture and structure, architectural elements of sediments, frequency of sedimentary successions, heavy-mineral analysis (both transparent and opaque heavy minerals, analysis of rounding and frosting of quartz

The Brazilian Continental Margin, which coastline measures more than 8,500km gives to Brazil continental dimensions. This huge region is conditioned by the action of process such as, sedimentals, tectonics, geomorphological and climatical, as example, which direct or in conjunction with other ones, since of continental break up between South America and Africa are going on and may be responsible for the current morphology of the margin. In accordance with this point of view, the Oriental part of the Brazilian Continental Margin, presents characteristics of a passive margin and fisiographically ''starved'', in which the continental break occur no more than 100km from de coastline and the sedimentary coverage is mainly carbonatic. The continental slope does not present great extension if compared with other parts of the Brazilian Margin and sharp gradient. The remark presence of the continental plateaus (Rio Grande Plateau and Pernambuco Plateau), which link with the continental rise and additionally the Paraiba, Pernambuco e Bahia seamounts, are the majors features in the morphology of the region between the slope and the continental rise. This paper will concentrate its focus on Bahia Seamount, with emphasis in the mainly erosive feature which cut transversally the seamounts, named Pernambuco Submarine Channel. It will be employed bathymetric multibeam and seismic data carried out by the Brazilian Continental Shelf Project (LEPLAC) in the current year and pieces of information from bibliographic researches in order to present a discussion by the hole of the Pernambuco Submarine Channel in the Occidental region of the Brazilian Continental Margin

The purpose of this study was to explore the types and predictors of immigration distress among Vietnamese women in transnational marriages in Taiwan. A cross-sectional survey with face-to-face interviews was conducted for data collection. A convenient sample of 203 Vietnamese women in transnational marriages in southern Taiwan was recruited. The Demographic Inventory measured the participants' age, education, employment status, religion, length of residency and number of children, as well as their spouse's age, education, employment status and religion. The Demand of Immigration Specific Distress scale measured the level of distress and had six subscales: loss, novelty, occupational adjustment, language accommodation, discrimination and alienation. Among the 203 participants, 6.4% had a high level of immigration distress; 91.1% had moderate distress; and 2.5% had minor distress. Higher mean scores were found for the loss, novelty and language accommodation subscales of the Demand of Immigration Specific Distress scale. Participant's (r = 0.321, p immigration distress. Length of residency in Taiwan (r = 0.576, p immigration distress. It indicated that the participants who had stayed fewer years in Taiwan had a higher level of immigrant distress. Health care professionals need to be aware that the female newcomers in transnational marriages are highly susceptible to immigration distress. The study suggests that healthcare professionals need to provide a comprehensive assessment of immigration distress to detect health problems early and administer culturally appropriate healthcare for immigrant women in transnational marriages.

2016-01-01

This study examined the morphological traits of 63 cocoa varieties that have been imported and cultivated in Vietnam. These cocoa varieties were collected from five regions in Southern Vietnam and were classified into three groups based on their phylogenetic relationships. Their morphological features were individually evaluated and analysed. This included leaf characteristics (leaf and stem anatomy) and flower features (ligule shape, anther number, pollen, stamen and ovule, fruit, seed). The results of this study showed a large variation across all morphological characteristics of the evaluated cocoa varieties. The Vietnamese cocoa flower showed a diversity of morphological characteristics including five shapes of ligule (oval, broad, deltoid, elliptic and sub-lanceolate) and each stamen also has a bilobed anther with the exception of trilobed anther for TD11. Furthermore, the shape of pollen grains was found homogeneous in all 63 varieties. The colour of the stamens and ovules was purple and white respectively for all examined samples. Three kinds of fruit shapes were identified, namely Angoleta, Amelonado and Cundeamor, and these were of various colours. Additionally, an anatomical analysis on the midrib structure of the leaves from the 63 varieties showed the highest similarity, likewise the stem structure. The colour of young leaves was observed as being green and red. This is the primary research that scrutinizes the morphological biodiversity of Vietnamese cocoa varieties during the three-decade development of the Vietnam cocoa project. The results have a practical applications for cocoa cross-breeding and botanical taxonomy. (author)

Intersecting Homeliness: Vietnamese Australian Reflections of a Suburban Home (Strathfield, NSW

Full Text Available In year 2013, I lived in Vietnam. Once a year, the Vietnamese people have a particular tradition called khom đất, where the people set out a guest table filled with delicious feast of food and paper clothing, shoes, accessories and money for the spirits of the house. Khom in khom đất means a set of rituals or prayer to bow down and pay respect. Đất means land. It is a ritual which acknowledges the spirits within the home and the agency these spirits have to the home. There would be separate rituals for different types of spirits and incense would burn as an offering to various places. For example, an incense and food offering would be on an alter directly above the fire stove in the kitchen to be grateful to the fire spirit of the home. There is a belief that if the fire spirit gets angry, the spirit may be a danger to the family. The spirit has the agency and a power over the home. It is a ritual to recognise that a home has its ghosts, its history and its spirits that reside long before the current people residents and that they have the power to protect or destroy. Mostly, it is to recognaise that land and place is not to be owned, and matters such as fire or water or wood is not mere commodities. Rather, these materialities are living and only would be at our disposal to help us when they given the respect and recognition that they are living and are powerful agents. Within the Vietnamese language, there is no specific word for differentiate ‘home’ and ‘house’ but rather, use the word ‘house’ to mean both the building and the home – nhà (Rather then state, ‘I go home’ one states literally, ‘I return to the house’ – Tôi về nhà. To state house rather than home could mean that home is not to be possessed but rather, has it’s own agency, vitality and spirit. With this in mind, I will tell you about a particular uncanny phenomenon that has happened in my family home in Strathfield (a loved family home where

Hepatitis C virus (HCV) 6a accounts for 23.6% of all HCV infections of the general population and 58.5% of intravenous drug users in Hong Kong. However, the geographical origin of this highly predominant HCV subgenotype is largely unknown. This study explores a hypothesis for one possible transmission route of HCV 6a to Hong Kong. NS5A sequences derived from 26 HCV 6a samples were chosen from a five year period (1999-2004) from epidemiologically unrelated patients from Hong Kong. Partial-NS5A sequences (513-bp from nt 6728 to 7240) were adopted for Bayesian coalescent analysis to reconstruct the evolutionary history of HCV infections in Hong Kong using the BEAST v1.3 program. A rooted phylogenetic tree was drawn for these sequences by alignment with reference Vietnamese sequences. Demographic data were accessed from "The Statistic Yearbooks of Hong Kong". Bayesian coalescent analysis showed that the rapid increase in 6a infections, which had increased more than 90-fold in Hong Kong from 1986 to 1994 correlated to two peaks of Vietnamese immigration to Hong Kong from 1978 to 1997. The second peak, which occurred from 1987 through 1997, overlapped with the rapid increase of HCV 6a occurrence in Hong Kong. Phylogenetic analyses have further revealed that HCV 6a strains from Vietnam may be ancestral to Hong Kong counterparts. The high predominance of HCV 6a infections in Hong Kong was possibly associated with Vietnamese immigration during 1987-1997.

Fishers and Territorial Anxieties in China and Vietnam: Narratives of the South China Sea Beyond the Frame of the Nation

Directory of Open Access Journals (Sweden)

Edyta Roszko

2016-12-01

Full Text Available In the geopolitical conflict over the South China Sea (SCS, fishers are at the center of Chinese and Vietnamese cartographic imaginations that define the sea as either “Chinese” or “Vietnamese” and hence tied to the disputed territories of the Paracel and Spratly Islands. While their historical presence and customary fishing rights in the SCS have been much publicized in the context of this territorial dispute, the long-standing Cham seafaring trade networks and legacy are ignored by both countries. The ethnic and national categories of Cham, Việt, and Han intersect with occupational categories such as those of fisher, trader, shipbuilder, sailor, and pirate, which in the past represented shifting, relational, and situational activities by the same people. The contemporary use of such professional and national labels produces particular political effects by projecting recent closures and enclosures onto the past, in spite of the common historical, cultural, and ethnic flows that always existed in the SCS. Rather than aiming to legitimize or delegitimize Vietnam’s or China’s territorial claims to the SCS, this article argues that seafaring narratives should be liberated from abstract, anachronistic discourses of sovereignty, territoriality, and territorial anxieties that separate the interconnected histories of the Cham, Vietnamese, and Chinese.

We developed the first Vietnamese internalized homophobia (IH) scale, for use with Vietnamese sexual minority women (SMW). Drawing from existing IH scales in the international literature and based on prior qualitative research about SMW in the Viet Nam context, the scale covers two domains: self-stigma (negative attitudes toward oneself as a sexual minority person) and sexual prejudice (negative attitudes toward homosexuality/same-sex relations in general). Scale items, including items borrowed from existing scales and items based on local expressions, were reviewed and confirmed by members of the target population. Quantitative evaluation used data from an anonymous web-based survey of Vietnamese SMW, including those who identified as lesbian (n=1187), or as bisexual (n=641) and those who were unsure about their sexual identity (n=353). The scale was found to consist of two highly correlated factors reflecting self-stigma (not normal/wholesome and self-reproach and wishing away same-sex sexuality) and one factor reflecting sexual prejudice, and to have excellent internal consistency. Construct validity was evidenced by subscales’ associations with a wide range of hypothesized correlates including perceived sexual stigma, outness, social support, connection to other SMW, relationship quality, psychological well-being, anticipation of heterosexual marriage and endorsement of same-sex marriage legalization. Self-stigma was more strongly associated with psychosocial correlates and sexual prejudice was more associated with endorsement of legal same-sex marriage. The variations in these associations across the hypothesized correlates and across sexual identity groups were consistent with the Minority Stress Model and the IH literature, and exhibited context-specific features, which are discussed.

Multidecadal fCO2 Increase Along the United States Southeast Coastal Margin

Science.gov (United States)

Reimer, Janet J.; Wang, Hongjie; Vargas, Rodrigo; Cai, Wei-Jun

2017-12-01

Coastal margins could be hotspots for acidification due to terrestrial-influenced CO2 sources. Currently there are no long-term (>20 years) records from biologically important coastal environments that could demonstrate sea surface CO2 fugacity (fCO2) and pH trends. Here, multidecadal fCO2 trends are calculated from underway and moored time series observations along the United States southeast coastal margin, also referred to as the South Atlantic Bight (SAB). fCO2 trends across the SAB, derived from ˜26 years of cruises and ˜9.5 years from a moored time series, range from 3.0 to 4.5 µatm yr-1, and are greater than the open ocean increases. The pH decline related to the fCO2 increases could be as much as -0.004 yr-1; a rate greater than that expected from atmospheric-influenced pH alone. We provide evidence that fCO2 increases and pH decreases on an ocean margin can be faster than those predicted for the open ocean from atmospheric influence alone. We conclude that a substantial fCO2 increase across the marginal SAB is due to both increasing temperature on the middle and outer shelves, but to lateral land-ocean interactions in the coastal zone and on inner shelf.

'Soft' human resource management in small international joint ventures:Cases from the Danish-Vietnamese context

2012-01-01

This paper examines the value creation aspects of HRM in international joint ventures of a relatively small size and their implications for strategic management. We assume that HRM in this context is rather a process than a function, and a ‘soft’ – humanistic rather than a ‘hard’, instrumentalist managerial approach. Using cases from a modest sample of Danish – Vietnamese joint ventures, we propose that HRM is significantly associated with creating a healthy and adaptive environment for mutua...

The tectonic significance of the Cabo Frio Tectonic Domain in the SE Brazilian margin: a Paleoproterozoic through Cretaceous saga of a reworked continental margin

Directory of Open Access Journals (Sweden)

Renata da Silva Schmitt

Full Text Available ABSTRACT: The Cabo Frio Tectonic Domain is composed of a Paleoproterozoic basement tectonically interleaved with Neoproterozoic supracrustal rocks (Buzios-Palmital successions. It is in contact with the Neoproterozoic-Cambrian Ribeira Orogen along the SE Brazilian coast. The basement was part of at least three continental margins: (a 1.97 Ga; (b 0.59 - 0.53 Ga; (c 0.14 Ga to today. It consists of continental magmatic arc rocks of 1.99 to 1.94 Ga. Zircon cores show a 2.5 - 2.6 Ga inheritance from the ancient margin of the Congo Craton. During the Ediacaran, this domain was thinned and intruded by tholeiitic mafic dykes during the development of an oceanic basin at ca. 0.59 Ma. After the tectonic inversion, these basin deposits reached high P-T metamorphic conditions, by subduction of the oceanic lithosphere, and were later exhumed as nappes over the basement. The Cabo Frio Tectonic Domain collided with the arc domain of the Ribeira Orogen at ca. 0.54 Ga. It is not an exotic block, but the eastern transition between this orogen and the Congo Craton. Almost 400 m.y. later, the South Atlantic rift zone followed roughly this suture, not coincidently. It shows how the Cabo Frio Tectonic Domain was reactivated as a continental margin in successive extensional and convergent events through geological time.

The Dual Role a Buddhist Monk Played in the American South: The Balance between Heritage and Citizenship in the Refugee Community

Directory of Open Access Journals (Sweden)

Daniel Rhodes

2016-05-01

Full Text Available Buddhist Monks in Vietnam struggle with cultural preservation differently from a monk in the U.S. where the forces of acculturation for new arrivals, often refugees, are extraordinarily overwhelming. The author provides a case study examining how Buddhist leaders engage in cultural preservation and community building in the American South. Fusing ideas of Engaged Buddhism and community building, the author will demonstrate how a Buddhist monk is able to navigate the broader American culture and assist Vietnamese immigrants and refugees to acculturate, while maintaining their own cultural heritage, beliefs and religious traditions; ultimately building a viable and sustainable Buddhist community that contributes greatly to its new host community.

Tectonic migration is a common geological process of basin formation and evolution. However, little is known about tectonic migration in the western Pacific margins. This paper focuses on the representative Cenozoic basins of East China and its surrounding seas in the western Pacific domain to discuss the phenomenon of tectonic jumping in Cenozoic basins, based on structural data from the Bohai Bay Basin, the South Yellow Sea Basin, the East China Sea Shelf Basin, and the South China Sea Continental Shelf Basin. The western Pacific active continental margin is the eastern margin of a global convergent system involving the Eurasian Plate, the Pacific Plate, and the Indian Plate. Under the combined effects of the India-Eurasia collision and retrogressive or roll-back subduction of the Pacific Plate, the western Pacific active continental margin had a wide basin-arc-trench system which migrated or ‘jumped’ eastward and further oceanward. This migration and jumping is characterized by progressive eastward younging of faulting, sedimentation, and subsidence within the basins. Owing to the tectonic migration, the geological conditions associated with hydrocarbon and gashydrate accumulation in the Cenozoic basins of East China and its adjacent seas also become progressively younger from west to east, showing eastward younging in the generation time of reservoirs, seals, traps, accumulations and preservation of hydrocarbon and gashydrate. Such a spatio-temporal distribution of Cenozoic hydrocarbon and gashydrate is significant for the oil, gas and gashydrate exploration in the East Asian Continental Margin. Finally, this study discusses the mechanism of Cenozoic intrabasinal and interbasinal tectonic migration in terms of interplate, intraplate and underplating processes. The migration or jumping regimes of three separate or interrelated events: (1) tectonism-magmatism, (2) basin formation, and (3) hydrocarbon-gashydrate accumulation are the combined effects of the

Mesozoic Compressional Folds of the Nansha Waters, Southern South China Sea

As an important part of the South China Sea, the southern margin of the South China Sea is fundamental to understand the interaction of the Eurasian, Pacific and Indian-Australian plates and the evolution of the South China Sea. Some multi-channel seismic profiles of the Nansha waters together with published drillings and dredge data were correlated for interpretation. The strata of the study region can be divided into the upper, middle and lower structural layers. The upper and middle structural layers with extensional tectonics are Cenozoic; the lower structural layer suffered compression is Mesozoic. Further structural restoration was done to remove the Cenozoic tectonic influence and to calculate the Mesozoic tectonic compression ratios. The results indicate that two diametrically opposite orientations of compressive stress, S(S)E towards N(N)W orientation and N(N)W towards S(S)E orientation respectively, once existed in the lower structural layer of the study area and shared the same variation trend. The compression ratio values gradually decrease both from the north to the south and from the west to the east in each stress orientation. The phenomena may be related to the opening of the proto-South China Sea (then located in south of the Nansha block) and the rate of the Nansha block drifted northward in Late Jurassic to Late Cretaceous, which had pushed the Nansha block drifted northward until it collided and sutured with the Southern China Margin. Thus the opening of the present-day South China Sea may be related to this suture zone, which was tectonically weakness zone.Key words: Mesozoic compression; structural restoration; proto-South China Sea; Nansha waters; Southern South China Sea; Acknowledgements: The work was granted by the National Natural Science Foundation of China (Grant Nos. 41476039, 91328205, 41576068 and 41606080).

Pekin ducks were infected by the mucosal route (oral, nasal, ocular) with one of two strains of Eurasian lineage H5N1 highly pathogenic avian influenza virus: A/Muscovy duck/Vietnam/453/2004 and A/duck/Indramayu/BBVW/109/2006 (from Indonesia). Ducks were killed humanely on days 1, 2, 3, 5 and 7 after challenge, or whenever morbidity was severe enough to justify euthanasia. Morbidity was recorded by observation of clinical signs and cloacal temperatures; the disease was characterized by histopathology; tissue tropism was studied by immunohistochemistry and virus titration on tissue samples; and viral shedding patterns were determined by virus isolation and titration of oral and cloacal swabs. The Vietnamese strain caused severe morbidity with fever and depression; the Indonesian strain caused only transient fever. Both viruses had a predilection for a similar range of tissue types, but the quantity of tissue antigen and tissue virus titres were considerably higher with the Vietnamese strain. The Vietnamese strain caused severe myocarditis and skeletal myositis; both strains caused non-suppurative encephalitis and a range of other inflammatory reactions of varying severity. The principal epithelial tissue infected was that of the air sacs, but antigen was not abundant. Epithelium of the turbinates, trachea and bronchi had only rare infection with virus. Virus was shed from both the oral and cloacal routes; it was first detected 24 h after challenge and persisted until day 5 after challenge. The higher prevalence of virus from swabs from ducks infected with the Vietnamese strain indicates that this strain may be more adapted to ducks than the Indonesia strain.

Full Text Available Aims. To investigate H. pylori infection rate and evaluate a combined set of tests for H. pylori diagnosis in Vietnamese patients with acute peptic ulcer bleeding (PUD. Methods. Consecutive patients with acute PUB were enrolled prospectively. Rapid urease test (RUT with 3 biopsies was carried out randomly. Patients without RUT or with negative RUT received urea breath test (UBT and serological and urinary H. pylori antibody tests. H. pylori was considered positive if RUT or any noninvasive test was positive. Patients were divided into group A (RUT plus noninvasive tests and group B (only noninvasive tests. Results. The overall H. pylori infection rate was 94.2% (161/171. Groups A and B had no differences in demographic characteristics, bleeding severity, endoscopic findings, and proton pump inhibitor use. H. pylori-positive rate in group A was significantly higher than that in group B (98.2% versus 86.7%, p=0.004. The positive rate of RUT was similar at each biopsy site but significantly increased if RUT results from 2 or 3 sites were combined (p<0.05. Conclusions. H. pylori infection rate in Vietnamese patients with acute PUB is high. RUT is an excellent test if at least 2 biopsies are taken.

2011-01-01

Full Text Available Abstract Background Intergenerational transmission of trauma as a determinant of mental health has been studied in the offspring of Holocaust survivors and combat veterans, and in refugee families. Mainly negative effects on the children are reported, while a few studies also describe resilience and a possible positive transformation process. A longitudinal prospective cohort study of Vietnamese refugees arriving in Norway in 1982 reports a 23 years follow-up, including spouses and children born in Norway, to study the long-term effects of trauma, flight, and exile on the offspring of the refugees. Objectives of the study: 1. To study the association between the psychological distress of Vietnamese refugee parents and their children after 23 years resettlement. 2. To analyse paternal predictors for their children's mental health. Methods Information from one or both parents at arrival in 1982 (T1, at follow-up in 1985 (T2, and 23 years after arrival (T3 was included. The mental health was assessed by the Global Severity Index (GSI of the self-report Symptom Check List-90-R (SCL-90-R for parents (n = 88 and older children (age 19-23 yrs, n = 12, while children aged 4-18 (n = 94 were assessed using the Strengths and Difficulties Questionnaire (SDQ. Results Thirty percent of the families had one parent with a high psychological distress score ("probable caseness" for a mental disorder, while only 4% of the children aged 10 - 23 years were considered as probable cases. In spite of this, there was an association between probable caseness in children and in fathers at T3. A significant negative paternal predictor for the children's mental health at T3 was the father's PTSD at arrival in Norway, while a positive predictor was the father's participation in a Norwegian network three years after arrival. Conclusions Children of refugees cannot be globally considered at risk for mental health problems. However, the preceding PTSD in their fathers may

Full Text Available Marine-derived natural products from invertebrates comprise an extremely diverse and promising source of the compounds from a wide variety of structural classes. This study describes the discovery of five marine natural products with activity against Trypanosoma species by natural product library screening using whole cell in vitro assays. We investigated the anti-trypanosomal activity of the extracts from the soft corals and echinoderms living in Vietnamese seas. Of the samples screened, the methanolic extracts of several marine organisms exhibited potent activities against cultures of Trypanosoma brucei and T. cruzi (EC50 < 5.0 μg/mL. Among the compounds isolated from these extracts, laevigatol B (1 from Lobophytum crassum and L. laevigatum, (24S-ergost-4-ene-3-one (2 from Sinularia dissecta, astropectenol A (3 from Astropecten polyacanthus, and cholest-8-ene-3β,5α,6β,7α-tetraol (4 from Diadema savignyi showed inhibitory activity against T. brucei with EC50 values ranging from 1.57 ± 0.14 to 14.6 ± 1.36 μM, relative to the positive control, pentamidine (EC50 = 0.015 ± 0.003 μM. Laevigatol B (1 and 5α-cholest-8(14-ene-3β,7α-diol (5 exhibited also significant inhibitory effects on T. cruzi. The cytotoxic activity of the pure compounds on mammalian cells was also assessed and found to be insignificant in all cases. This is the first report on the inhibitory effects of marine organisms collected in Vietnamese seas against Trypanosoma species responsible for neglected tropical diseases.

Intervertebral disc degeneration (IDD) is one of the most common skeletal disorders, yet few data are available in Asian populations. We sought to assess the prevalence and pattern of radiographic IDD in a Vietnamese population. This population-based cross-sectional investigation involved 170 men and 488 women aged ≥40 years, who were randomly sampled from the Ho Chi Minh City (Vietnam). Anthropometric data, clinical history and self-reported back and neck pain were ascertained by a questionnaire. Plain radiographs (from the cervical spine, thoracic spine to the lumbar spine) were examined for the presence of disc space narrowing and/or osteophytosis using the Kellgren-Lawrence (KL) grading system. The presence of radiographic IDD was defined if the KL grade was 2 or greater in at least one disc. The prevalence of radiographic IDD was 62.4% (n = 106) in men and 54.7% (n = 267) in women. The most frequently affected site was the lumbar spine with prevalence being 50.6 and 43.2% in men and women, respectively. The prevalence of IDD increased with advancing age: 18.8% among those aged 40-49 years, and increased to 83.4% in those aged ≥60 years. Self-reported neck pain and lower back pain were found in 30 and 44% of individuals, respectively. There was no statistically significant association between self-reported neck pain and cervical spine OA. These data suggest that radiographic IDD is highly prevalent in the Vietnamese population, and that self-reported back pain is not a sensitive indicator of IDD.

Cocoa cultivation has increased in tropical areas around the world, including Vietnam, due to the high demand of cocoa beans for chocolate production. The genetic diversity of cocoa genotypes is recognized to be complex, however, their phylogenetic relationships need to be clarified. The present study aimed to classify the cocoa genotypes, that are imported and cultivated in Vietnam, based on a chloroplast DNA region. Sixty-three Vietnamese Cocoa accessions were collected from different regions in Southern Vietnam. Their phylogenetic relationships were identified using the universal primers c-B49317 and d-A49855 from the chloroplast DNA region. The sequences were situated in the trnL intron genes which are identify the closest terrestrial plant species of the chloroplast genome. DNA sequences were determined and subjected to an analysis of the phylogenetic relationship using the maximum evolution method. The genetic analysis showed clustering of 63 cocoa accessions in three groups: the domestically cultivated Trinitario group, the Indigenous cultivars, and the cultivations from Peru. The analyzed sequencing data also illustrated that the TD accessions and CT accessions were related genetically closed. Based on those results the genetic relation between PA and NA accessions was established as the hybrid origins of the TD and CT accessions. Some foreign accessions, including UIT, SCA and IMC accessions were confirmed of their genetic relationship. The present study is the first report of phylogenetic relationships of Vietnamese cocoa collections. The cocoa program in Vietnam has been in development for thirty years. (author)

Research on extramarital sex (EMS) is commonly conducted from a perspective that implicitly understands this behavior as a violation of the marital relationship. In contrast, Vietnamese cultural norms have, at some points in history, condoned if not outright encouraged EMS in the name of preserving family lineage. Yet little is known about the prevalence of EMS among contemporary Vietnamese men and its association with marriage quality. This is a notable gap, given the enormous sociocultural and ideological shifts the country has experienced over the past several decades. Drawing upon a sample of 126 married men (Mean age = 45.56; SD = 10.52) surveyed in urban (Hanoi and Ho Chi Minh City) and rural areas (Ha Tay and Can Tho) in Vietnam, we examined the relationship between EMS and geographic region, demographic characteristics, sexual values, quality of marriage, and sexual satisfaction within marriage. Our results show that geographic location had a strong impact on EMS, while most marital relationship quality variables did not impact the odds of EMS for married men in Vietnam.

We sought to better understand the association between early life exposure to war and trauma and older adult health status in a developing setting. We analyzed data of 405 Vietnamese men and women in 1 northern Vietnam commune who entered early adulthood during the Vietnam War and who are now entering late adulthood (i.e., ages 55 years and older in 2010). The toll of war's trauma in the aging northern Vietnamese population was perceptible in the association between exposure to war trauma and various measures of physical health, including negative self-reported health and somatic symptoms. Killing another person and being exposed to toxic substances in warfare was especially detrimental to health in older adulthood. War traumas were likely implicated more strongly as determinants of late adulthood health in men than in women. The weak association between trauma exposure and reported depressive symptoms raised questions about measuring mental health. Military service and war trauma were important determinants of older adult health beyond the US context, given the widespread waging of war and concentration of recent armed conflicts within developing societies.
