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

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

Driving Factors for Green Innovation in Vietnamese Construction Enterprises

Purpose: The aim of this study is to examine the influences of different factors on green innovation in Vietnamese construction enterprises.   Theoretical framework: The theoretical framework is built upon the resource-based view, the model of organizational innovation, and stakeholder theory.   Design/methodology/approach: The research carries out a literature survey related to construction enterprises, then empirical analysis is conducted among 450 employees and managers at all level working in this field with the results analyzed using Cronbach’s Alpha analysis, exploratory factor analysis, pearson correlation analysis, linear regression analysis and One - way ANOVA analysis.   Findings: The results demonstrate that using renewable energy is well represented for green innovation in the Vietnamese construction industry and quantitative results also show positive impacts of all factors studied on green innovation: Green dynamic capabilities, Green creativity, Green knowledge sharing, Corporate environmental ethics, Pressure from industry competitors and regulators. In addition, the result affirmed there are statistically significant differences in the level of green innovation between construction enterprises of size and age, but not types of firm.   Research, Practical & Social implications: The study proposes solutions for both enterprises and regulators – one of the external stakeholders to develop green innovation in the construction sector. 

Kaehler Differential Algebras for 0-Dimensional Schemes and Applications

The aim of this dissertation is to investigate Kaehler differential algebras and their Hilbert functions for 0-dimensional schemes in P^n. First we give relations between Kaehler differential 1-forms of fat point schemes and another fat point schemes. Then we determine the Hilbert polynomial and give a sharp bound for the regularity index of the module of Kaehler differential m-forms, for 0<m<n+2. Next, we examine the Kaehler differential algebras for fat point schemes whose supports lie on non-singular conics in P^2. Finally, we prove the Segre bounds for equimultiple fat point schemes in P^4, this result allows us to determine the regularity index of the module of Kaehler differential 1-forms, and a sharp bound for the regularity index of the module of Kaehler differential m-forms, for 1<m<6

A Study of Vietnam Hotel Customers Information Searching Behavior

顾客的信赖、顾客的满意度及顾客的忠诚度是每家酒店企业走向成功的重要因素。以往的研究表明，顾客购买行为过程中的信息搜寻环节，对顾客做出最后的购买决策有重要影响。随着移动互联网的不断发展，信息的传播范围也越来越广泛。为了规避风险或满足某种需求，在决定购买产品或服务之前消费者倾向于通过各种各样的渠道进行大量的信息搜寻。然而信息传播的速度之快，将导致消费者的购买决策可能会随着信息的不断更新而改变，企业也将难以准确预测消费者的购买行为。本文从消费者信息搜寻行为入手，以越南酒店的顾客为研究对象，在前人的研究基础上，构建研究模型，并通过问卷调查的实证研究方法，对酒店顾客的信息搜寻及影响因素进行了探究，并为越...The trust of customers,customer satisfaction and customer loyalty is an important factor for each hotel business success. Previous studies have shown that customer buying behavior in the process of information search link,have a major impact on the customer to make the final purchase decision. As the mobile Internet continues to grow,the circulation of information more and more widely. In order to...学位：文学硕士院系专业：管理学院_企业管理(含财务管理、市场营销、人力资源管理)学号：1762010115432

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
