The policy cycle and vernacular globalization: a case study of the creation of Vietnam National University—Hochiminh City     

Thanh Minh Ngo  Bob Lingard 《比较教育学》2006,42(2):225-242

This article examines the policy cycle and vernacular globalization in the context of higher education reform in Vietnam. Through an analysis of the development of the Vietnam National University—Hochiminh City as part of the post‐1986 reconstruction of Vietnamese higher education, the article considers the complex interrelationship between globalized policy discourses, national interests and history in Vietnam, and the specific politics of policy implementation within one institution. Vietnam National University—Hochiminh City was created through an amalgamation of a number of smaller universities, and against the backdrop of social and economic restructuring aimed at promoting industrialization and a market orientation within socialist governance. The article reveals the dynamic tension between these local and global influences on higher education policy and practice, and more specifically, the dilemmas associated with top‐down policy implementation when a new organization consists of older organizations with powerful provenance and reputations. In so doing the article demonstrates the necessity to globalize policy theory.  相似文献

Comparison of 3D reconstructive technologies used for morphometric research and the translation of knowledge using a decision matrix

The use of three‐dimensional (3D) models for education, pre‐operative assessment, presurgical planning, and measurement have become more prevalent. With the increase in prevalence of 3D models there has also been an increase in 3D reconstructive software programs that are used to create these models. These software programs differ in reconstruction concepts, operating system requirements, user features, cost, and no one program has emerged as the standard. The purpose of this study was to conduct a systematic comparison of three widely available 3D reconstructive software programs, Amira^®, OsiriX, and Mimics^®, with respect to the software's ability to be used in two broad themes: morphometric research and education to translate morphological knowledge. Cost, system requirements, and inherent features of each program were compared. A novel concept selection tool, a decision matrix, was used to objectify comparisons of usability of the interface, quality of the output, and efficiency of the tools. Findings indicate that Mimics was the best‐suited program for construction of 3D anatomical models and morphometric analysis, but for creating a learning tool the results were less clear. OsiriX was very user‐friendly; however, it had limited capabilities. Conversely, although Amira had endless potential and could create complex dynamic videos, it had a challenging interface. These results provide a resource for morphometric researchers and educators to assist the selection of appropriate reconstruction programs when starting a new 3D modeling project.

Micromixer based on viscoelastic flow instability at low Reynolds number   总被引：1，自引：0，他引：1  

Y. C. Lam  H. Y. Gan  N. T. Nguyen    H. Lie 《Biomicrofluidics》2009,3(1)

We exploited the viscoelasticity of biocompatible dilute polymeric solutions, namely, dilute poly(ethylene oxide) solutions, to significantly enhance mixing in microfluidic devices at a very small Reynolds number, i.e., Re≈0.023, but large Peclet and elasticity numbers. With an abrupt contraction microgeometry (8:1 contraction ratio), two different dilute poly(ethylene oxide) solutions were successfully mixed with a short flow length at a relatively fast mixing time of <10 μs. Microparticle image velocimetry was employed in our investigations to characterize the flow fields. The increase in velocity fluctuation with an increase in flow rate and Deborah number indicates the increase in viscoelastic flow instability. Mixing efficiency was characterized by fluorescent concentration measurements. Our results showed that enhanced mixing can be achieved through viscoelastic flow instability under situations where molecular-diffusion and inertia effects are negligible. This approach bypasses the laminar flow limitation, usually associated with a low Reynolds number, which is not conducive to mixing.  相似文献   

Neural information retrieval: at the end of the early years

A recent “third wave” of neural network (NN) approaches now delivers state-of-the-art performance in many machine learning tasks, spanning speech recognition, computer vision, and natural language processing. Because these modern NNs often comprise multiple interconnected layers, work in this area is often referred to as deep learning. Recent years have witnessed an explosive growth of research into NN-based approaches to information retrieval (IR). A significant body of work has now been created. In this paper, we survey the current landscape of Neural IR research, paying special attention to the use of learned distributed representations of textual units. We highlight the successes of neural IR thus far, catalog obstacles to its wider adoption, and suggest potentially promising directions for future research.  相似文献   

Why Do University Students Refrain from Using E-Books in Libraries? Empirical Evidence from Vietnam     

Thu Hang Hoang  Ninh Nguyen 《Publishing Research Quarterly》2018,34(4):568-572

E-books have increasingly penetrated the academic world. However, despite efforts from Vietnamese universities and colleges to establish and broaden their e-books collection, students seem reluctant to use these digital books. This study aims to examine the barriers to using e-books in libraries among Vietnamese students. Data were obtained from 355 undergraduate students who were interested in e-books. The findings demonstrate that some key barriers impeding students from using e-books include the lack of computers and e-books in libraries, limited information and knowledge about e-books and their preference of using print books. Interestingly, female students tend to perceive the barriers to be stronger than their male counterparts. This study’s findings have important implications for universities, libraries and publishers who seek to promote e-books to students.  相似文献   

Promoting the Purchase of Textbooks in the Vietnamese Higher Education Sector     

Thi Thu Hoai Phan  Tuan Khanh Cao  Thu Hang Hoang  Phuong Anh Vu  The Ninh Nguyen 《Publishing Research Quarterly》2018,34(1):89-95

Higher education textbooks sales account for a significant portion of the overall book market. This study makes an important contribution to the extant literature by examining students’ purchase of original textbooks in a developing market, Vietnam. Notably, it seeks to investigate why students do not purchase original textbooks as well as the difference in purchase behavior between different groups of students. The findings reveal that some key obstacles to students’ purchase behavior include high prices, insufficient availability, low perceived value, and the emergence of pirated textbooks. Another notable finding is that senior students who are female tend to purchase more textbooks. In light of these findings, marketing strategies are suggested for publishers, bookstores and universities who aim to promote the sales and consumption of original textbooks.  相似文献   

Public Opinion Polls,Chicken Soup and Sample Size

Cooking and tasting chicken soup in three different pots of very different size serves to demonstrate that it is the absolute sample size that matters the most in determining the accuracy of the findings of the poll, not the relative sample size, i.e. the size of the sample in relation to its population.  相似文献   

Marketing International Scholarly Journals to Vietnamese Researchers     

The Ninh Nguyen  Hoang Viet Nguyen  Hoang Nguyen 《Publishing Research Quarterly》2017,33(4):471-476

There is a significantly growing interest in publishing in international scholarly journals in Vietnam. On the one hand, Vietnamese researchers can be potential authors of interesting articles that provide new insights into the emerging economic context. On the other hand, they can be target consumers and subscribers of journals in their quest for academic and practical knowledge. This paper aims to propose marketing initiatives for publishers and editors who seek to promote their journals to researchers in emerging countries, particularly Vietnam. These marketing solutions build upon an understanding of barriers for researchers in international publications.  相似文献
