Supply Chain Management Practices, Competitive Advantages and Firm Performance： A Case of Small and Medium Enterprises （SMEs） in Vietnam

引用

Journal of Modern Accounting and Auditing 2018年第3期14卷 136-146页

作者： Duong Vu Xuan Quynh nguyen hoang huy International University-Vietnam National University Ho Chi Minh City Vietnam

The perception of supply chain management （SCM） first appeared in 1982 and the very first papers on SCM were published in the mid 1980s （Houlihan, 1985）. However, this term is still fresh in Vietnam, especially the subject of SCM practices and their impacts on firm performance of small and medium enterprises （SMEs）. Therefore, the research was conducted to study the impact of supply chain management practices （SCMPs） on firm performance of SMEs through firm competitive advantages. Data were collected by surveying SMEs located in Ho Chi Minh City. The research findings showed that customer relationship （CR） and quality of information sharing （IQ） impact on firm performance at 0.01% significance level while the level of information sharing impacts on firm performance at 10% significance level, and strategic supplier partnership impacts on firm performance insignificantly. Moreover, we also found that customer relationship and quality of information sharing influence firm competitive advantage at 0.01% significance level, while strategic supplier partnership and the quality of information sharing impact on firm competitive advantage at 5% significance level. Competitive advantages impact significantly positively on firm performance at significance level of 0.001%. The findings imply that SMEs in Vietnam should manage customer relationship well and increase the level of information quality to improve competitive advantage in order to gain high performance.

In multimodal learning, Vision-Language Models (VLMs) have become a critical research focus, enabling the integration of textual and visual data. These models have shown significant promise across various natural language processing tasks, such as visual question answering and computer vision applications, including image captioning and image-text retrieval, highlighting their adaptability for complex, multimodal datasets. In this work, we review the landscape of Bootstrapping Language-Image Pre-training (BLIP) and other VLM techniques. A comparative analysis is conducted to assess VLMs’ strengths, limitations, and applicability across tasks while examining challenges such as scalability, data quality, and fine-tuning complexities. The work concludes by outlining potential future directions in VLM research, focusing on enhancing model interpretability, addressing ethical implications, and advancing multimodal integration in real-world applications.

"一带一路"倡议自提出以来就颇受包括越南在内的世界各国的广泛关注。本文旨在分析越南视角下的"一带一路"倡议。越南虽然对"一带一路"倡议表示欢迎和支持,但是对"一带一路"建设参与度不够,中越两国在寻找合作契合点方面还存在分歧。这在一定程度上与两国发表了许多政治和外交声明,但在执行方面仍面临障碍有关,比如贸易关系不平衡,公众就中国在越南基础设施项目质量的质疑和争议不断增加等。此外,双方缺乏互信也将阻碍越南参与"一带一路"建设。这些反过来也加大了两国政治承诺与执行实践之间的差距。因此,在建立了互信的基础后,中国如果能够确保有关国家相信"一带一路"倡议是合作共赢的机制,那么几乎所有相关国家都会积极响应。在这种背景下,中国将成为地区乃至全球的一个真正的大国和参与者。

Predicted aerodynamic damping of slender single beam structures in across-wind vibrations

Acta Mechanica Sinica 2020年第5期36卷 990-998,I0001页

作者： Cung huy nguyen Dinh Tung nguyen Department of Civil Engineering Industrial University of Ho Chi Minh CityHo Chi Minh City 700000Vietnam Department of Civil Engineering University of NottinghamNottingham NG72RDUK

The paper presents a generalization of the conventional analytical approach where the quasisteady theory is utilised to evalu-ate the across-wind aerodynamic damping of slender single beam *** generalized theory considers the variation of structural and aerodynamic parameters along the structural height,together with the nature of the vertical wind profile and mode ***-form solutions for typical uniform and tapered tall buildings are given.A numerical application on a prototype tall building shows that the conventional method may be oversimplified,which results in incorrect predictions of the aerodynamic damping.

Photocatalytic removal of NO and NO_2 using titania nanotubes synthesized by hydrothermal method

引用

Journal of Environmental Sciences 2014年第5期26卷 1180-1187页

作者： Nhat huy nguyen Hsunling Bai Institute of Environmental Engineering National Chiao Tung University

In this study, the photocatalysts of titania nanotubes （TNTs） were synthesized at different calcination temperatures using commercial Degussa TiO2 （P25） as a precursor. The materials were then characterized by BET, SEM, TEM, and XRD analyses. The photocatalytic reactions with NO and NO2 under UV-A irradiation were both performed. The results showed that the photocatalytic reaction rate of NO was much faster than that of NO2, and the conversion of NO2 to nitrate was the rate-limiting step for photocatalytic removal of NOx if the nitrate produced cannot be removed continuously from the photocatalyst surface. For TNTs calcined at different temperatures, a significant enhancement was observed on the total NOx removal efficiency by TNT calcined at 500℃ for both NO and NO2 photocatalytic reaction, which could be attributed to its high anatase crystallinity as well as high surface area. These two factors affect primarily on the NO2 conversion step in which the high anatase crystallinity could be responsible for the high efficiency at the beginning, while the high surface area could be accounted for retaining this high efficiency from nitric acid poisoning during the test period.
