Women as Fish: Physical Movement and Social Mobility in Contemporary Vietnam

This dissertation examines the changing rurality and the profound social stratification in contemporary Vietnam through the lens of rural-to-rural female migration. It is based on eighteen months of ethnographic research in a rural offshore fishing community in northern Vietnam called Hải Thành. I study the migration of two groups of women: 1) transnational women, who are young Hải Thành girls that marry Taiwanese and South Korean men, and migrate to mostly rural areas in East Asia, and 2) translocal women, who are women from other rural Vietnamese communities who migrate to Hải Thành to marry local men. My dissertation analyzes the relationship between movement and social class. It shows how female migration both sustains and transforms social hierarchies and binaries in unexpected ways via the embodiment of ethnicity, class, gender, age, and rurality, and practices of beauty, migration, education and morality. The double rural-to-rural female migration pattern in Hải Thành indicates that movement and social stratification are indicative of a complex rural landscape, and productive of modern and gendered rural subjectivities in Vietnam, which are produced through multiple political, cultural, historical and economic forces

Management current land use of perennial industrial crops by NDVI index: A case study in Chu Se District, Gia Lai Province, Vietnam: Research article

Remote sensing and Geographic Information System (GIS) - an effective tool for managing naturalresources, is quite common application in establishing thematic maps. However, the application of this modern technology in natural resource management has not yet been popular in Vietnam, particularly mapping the land use/cover. Currently, land use/cover map is constructed as traditional methods and gets limitations of management counting due to time-consuming for mapping andsynthesis the status of land use/cover. Hence, information on the map is often outdated and inaccurate.The main objective of this study is to upgrade the accuracies in mapping current perennialcrops in Chu Se District, Gia Lai Province in Vietnam by interpreted NDVI index (Normalized Difference Vegetation Index) from Landsat 8-OLI (Operational Land Imager). The results of studyis satisfied the urgent of practical requirement and scientific research. There are 3 types of perennial industrial plants in the study area including rubber, coffee, and pepper, in which most coffee isgrown, with an area of over 10,000 hectares. The results also show that integration of remote sensing and GIS technology enables to map current management and distribution of perennial industrialplants timely and accurately. This application is fully consistent with the trend of the world, and in accordance with regulations of established land use/cover map, and the process could be appliedat other districts /towns or in higher administrative units.Viễn thám và hệ thông tin địa lý (GIS) là công cụ hữu hiệu để quản lý tài nguyên thiên nhiên, được ứng dụng khá phổ biến để thành lập các loại bản đồ. Tuy nhiên, việc áp dụng công nghệ hiện đại này trong lĩnh vực quản lý tài nguyên thiên nhiên ở Việt Nam chưa phổ biến, nhất là công tác xây dựng bản đồ hiện trạng sử dụng/độ phủ đất. Việc xây dựng bản đồ hiện trạng hiện nay vẫn theo phương pháp truyền thống, thường gặp nhiều hạn chế do thời gian tổng hợp và xây dựng bản đồ hiện trạng kéo dài, dẫn đến thông tin trên bản đồ bị lạc hậu và không chính xác. Mục tiêu chính của nghiên cứu này là nâng cao độ chính xác kết quả giải đoán ảnh viễn thám Landsat 8 bằng chỉ số NDVI (chỉ số khác biệt thực vật) để thành lập bản đồ hiện trạng sử dụng đất cây công nghiệp lâu năm ở huyện Chư Sê, tỉnh Gia Lai, Việt Nam. Từ đó quản lý hiện trạng sử dụng loại đất này phù hợp yêu cầu cấp bách thực tiễn sản xuất và nghiên cứu khoa học. Kết quả của nghiên cứu cho thấy có 3 loại hình cây công nghiệp trên địa bàn nghiên cứu gồm cây cao su, cà phê và hồ tiêu, trong đó cây cà phê được trồng nhiều nhất, với diện tích hơn 10.000 ha. Nghiên cứu cũng cho thấy, tích hợp công nghệ viễn thám và GIS cho phép quản lý hiện trạng và phân bố cây công nghiệp trong không gian một cách hiệu quả và nhanh chóng. Ứng dụng này hoàn toàn phù hợp với xu hướng của thế giới, đồng thời theo đúng quy định thành lập bản đồ hiện trạng sử dụng đất, và quy trình này có thể thực hiện được ở cấp huyện/thị xã hoặc đơn vị hành chính cấp cao hơn

QUALITY OF SUSTAINABILITY REPORTING AND BANK STABILITY: EMPIRICAL EVIDENCE FROM VIETNAMESE COMMERCIAL BANKS

The purpose of this study is twofold. First, we attempt to quantify the quality of bank sustainability reporting (QSR) since the 2016 mandatory sustainability disclosure in Vietnam. Content analysis of banks’ annual reports is performed to assess 11 QSR items that are used to build the QSR index. Second, we investigate whether the quality of sustainability reporting influences banks’ financial stability. Employing a sample of 159 banking firm observations over the period 2016–2021, we document that the quality of sustainability reporting in Vietnamese commercial banks increased from year to year. Importantly, our empirical evidence shows that a higher level of QSR contributes to better bank stability. This result is robust to various estimation methods, different components of QSR, an alternative measure of bank stability, and controlling for reverse causality. Our findings provide important implications for bank managers by highlighting that the enhancement of QSR increases bank stability

フィルターパック法におけるHNO₃に係るサンプリングアーティファクトの評価

Nitric acid gas (HNO₃) is an important species in either atmospheric chemistry or removal of atmospheric nitrogen process, and its concentration needs to be determined precisely. This study provided an assessment on the sampling artifact of HNO₃ in the filter pack by using the method itself. In the first part, a validation method for HNO₃ concentration under the impact of chlorine loss reaction and sampling artifact related to sea salt and the dissociation of NH₄NO₃ was successfully introduced by the use of a step-by-step approach via “Initial” HNO₃ and “Primary” HNO₃. In the second part, by simultaneous employment of the multi-stage filter pack systems, the role of the artifact related to H₂SO₄ on HNO₃ concentration determined by filter pack was confirmed. By that point, the existence of ambient H₂SO₄ was revealed and its source was attributed to a domestic volcano and the transportation of northwestern airmasses.北九州市立大
