The development of a contextualised set of evaluation criteria for studying internationalisation at a Vietnamese public university : a dissertation presented in partial fulfilment of the requirements for the degree of Doctor of Philosophy in Education at Massey University, Manawatū, New Zealand

The aim of this thesis is to explore the development of a contextualised set of evaluation criteria for studying internationalisation at a Vietnamese public university. The literature on internationalisation has so far paid little attention to Vietnam, a context which is at an early stage in conceptualising a plan for its internationalisation. This thesis, therefore, will assist Vietnamese universities in this effort in order to become a part of the global higher education system. Having access to a set of relevant evaluation criteria will not only enable them to better understand their current level of internationalisation but also inform their future internationalisation strategy. The research process was supported by two conceptual frameworks: practical participation evaluation and utilization-focused evaluation approaches. A mixture of qualitative and quantitative research methods was employed to conduct the three-phase development of the contextualised set of evaluation criteria. A collaborative partnership was also developed with the institutional stakeholders from a key university for which the set of criteria was contextualised for evaluating the internationalisation process. The findings from this study indicated that the development of a contextualised set of evaluation criteria for internationalisation at a Vietnamese public university was informed by a complexity of contextual factors. In particular, the domestic-focused nature of institutional internationalisation was found to be shaped not only by national economic and political rationales but also the institutional structure of single focus on teaching. The complexity was further expanded to (national) cultural relevance, institutional purposes for the evaluation, and the institutional mono-disciplinary structure when it came to the evaluation of that internationalisation. As a result of the study, a modelling process for developing a contextualised set of criteria for internationalisation at Vietnamese public universities was established. Insights into the complexity of the process for contextualising a set of evaluation criteria to study internationalisation at a Vietnam university also led to implications and recommendations for institutional stakeholders at the key university in the study (policy implementers and senior leaders), other universities, and policy makers

Intrusion Detection In Wireless Sensor Networks

There are several applications that use sensor motes and researchers continue to explore additional applications. For this particular application of detecting the movement of humans through the sensor field, a set of Berkley mica2 motes on TinyOS operating system is used. Different sensors such as pressure, light, and so on can be used to identify the presence of an intruder in the field. In our case, the light sensor is chosen for the detection. When an intruder crosses the monitored environment, the system detects the changes of the light values, and any significant change meaning that a change greater than a pre-defined threshold. This indicates the presence of an intruder. An integrated web cam is used to take snapshot of the intruder and transmit the picture through the network to a remote station. The basic motivation of this thesis is that a sensor web system can be used to monitor and detect any intruder in a specific area from a remote location

Evaluating the Heterogeneous Effect of Firm Risk on Firm Value

Purpose- This paper aims to investigate the effect of firm risk on the firm value to see how the firm value is changing when the risk level is changed. Our result indicates that a higher level of risk can reduce firm value.  Design/Methodology- We apply a Bayesian causal technique for a sample data set of US public firms. The causal approach helps us to focus on the reliable and unbiased results instead of the association-based findings. Findings- The results show a negative effect of risk on the firms’ value for the sample data. However, we investigate the potential effect of the risk across the distribution of the firm value. We witness the more substantial effect of risk on firms with a higher value. Practical Implications- Helps firms to evaluate their risk and its effect, so they can adjust their decisions and take actions to reduce the undesired effects of firm risk

Impact of Economic Freedom and Corruption Perceptions Index on Foreign Direct Investment in Vietnam

Foreign direct investment is an important source of investment capital that is indispensable to contribute to each country's total investment capital. FDI attraction has always been of special interest to governments in both developed and developing countries. The empirical method was employed on a secondary time series data set during the period 1999-2018 to determine the impact of economic freedom index and corruption perceptions index on foreign direct investment in Vietnam by using the linear approach. The empirical results show that the relationship between corruption perceptions index and foreign direct investment is a positive sign at a 1% significant level. The effect of economic freedom index on foreign direct investment has a positive effect at a 5% significant level

Automatic detection of pavement crack feature on images taken from specialized road surface survey vehicle

Approaching to PDCA (Plan - Do - Check - Take Action) in management of infrastructure asset requires digital transformation, sufficient data and strong database supporting management, analysis as well as creation of data-driven decision making tools. For pavements, data including condition indicators such as roughness and rutting depth are collected automatically during the survey vehicle travelling. However, pavement crack ratio and crack features of pattern and segmentation have not been detected by the system but manual in the case in Vietnam. The paper presents result of research on algorithm of statistic machine learning model in AI applying deep learning algorithm to automatically detect crack feature on pavement photos for enhancement of the performance and productivity of current survey technology. In the research, a deep architecture using convolutional neural network (CNN) for crack segmentation on gray scale images has been developed. The results show the CNN model for crack segmentation is better than other methods using traditional digital processing such as the Gabor filters or threshold and machine learning such as Adaboost

Users\u27 Searching Behaviour in Using Online Databases at Vietnam National University - Ho Chi Minh City

Purpose: This paper focuses on identifying the searching behaviors of the users, their difficulties as well as their expectations from library supports while using online databases at the Central Library of Vietnam National University – Ho Chi Minh city. Methods: Usage Reports of six online databases subscribed by the Central Library were analyzed and a survey by emailing users a questionnaire was conducted. Findings: The amount of usage increases yearly, however it is still low in comparison with the amount of subscribers who have registered for using online databases. Users did search for their research and study rather than for their teaching or professional knowledge update. Often they looked for journal articles and thesis rather than e-book. Key words and titles were used the most when searching. Reading the guidance from the library websites or from the databases was most used. This suggested that most users did not know how to use the databases and preferred to learn by themselves. Email was user preferred mean to communicate with library staff. English language and database searching skills were the biggest barriers preventing users from employing online database. Originality and implication: This paper provides the understanding of users‟ behaviors and suggests the necessity to assist users in using online databases in Vietnam universities. Up to now, these issues have not been known. They are relevant to improve the utilization of online databases

Non-Competition Agreements Under Vietnamese Law: Protection of Trade Secrets and Free Choice of Employment as Two Sides of the Same Coin

If you ask many employers in Vietnam why they use non-competition agreements (noncompetes), they will confidently tell you that they are trying to protect their legitimate ownership interests. However, what they are less confident about is the legal enforceability of noncompetes. Such uncertainty hurts both employers and employees. The ambiguity regarding the enforceability of noncompetes not only discourages employers from bringing trade secrets into Vietnam but also deprives employees of opportunities for employer investment and personal development. In this article, we argue that noncompetes should be enforceable in Vietnam. However, noncompetes should be binding only if they are necessary to protect an employer’s trade secret(s). This article proposes that the employer must establish this necessity by satisfying the following five-element test. First, the employer has a protectable trade secret. Second, the employee performs work related to such trade secret. Third, the employer sufficiently informs the employee about the noncompete before the employee signs it. Fourth, the noncompete is reasonably limited in scope. Fifth, the employer offers separate consideration to the employee for signing the noncompete

The Integration of Constructivist and Sociocultural Learning Principles with ICT in Teaching Physics

To fulfil the requirement of nation development and globalisation, Vietnam’s Ministry of Education and Training (MOET) has introduced educational reforms at primary, secondary and tertiary levels that require Vietnamese teachers to acquire new understanding and skills in using information communication technology (ICT) to support teaching with a student-centred approach. There is, however, little literature to guide Vietnamese teachers on how to achieve these goals. This thesis aimed at developing, trialling and evaluation a theoretical pedagogic model for integrating student-centred learning principles with ICT for the teaching physics in the Vietnamese context. The project began with the development of an initial theoretical model based on a review of the relevant literature. This model was evaluated by New Zealand and Vietnamese experts and subsequently revised to form the CSI model (The Pedagogic Model of Integrating Constructivist and Sociocultural Learning Principles with ICT) used in the implementation phase of the project. The CSI Model was implemented by a lecturer in a university optics course and data was collected from different groups of people (students, observers, the lecturer and a teaching assistant) and by different methods (observations, optics tests, California Critical Thinking Skills Tests, interviews and surveys) to triangulate and enrich the data. The optics course was taught to two groups. The ICT implementation into optics teaching and learning in both groups was underpinned by the CSI Model. Students of one group (Morning Group) utilised more ICT applications than the other group (Afternoon Group): the Morning Group students’ learning was supported by a learning management system (LMS). The optics test results show that in both groups, the students’ scores in the post-test were statistically significantly higher than their scores in the pre-test. In addition, in the post-test, the group of students who utilised more applications of ICT to support their learning scored significantly higher than the other group. It is noted that there is no statistically significant difference in the pre-test scores of the two groups. Findings from student, lecturer and teaching assistant interviews revealed that most students in the two research groups felt that the way the optics course was taught enhanced their learning and made learning optics fun and exciting. Results from the California Critical Thinking Skills Tests also showed that post-test scores of the students in both research groups were significantly higher than their pre-test scores. In the post-test, the students scored significantly higher in both the total score as well as the individual scores for each critical thinking skill. In the research context, the CSI Model appears to be an effective pedagogic model. Findings showed that the model helped to improve the students’ physics test scores, enhanced their critical thinking skills, and increased interaction within the learning environment

Assessment of earthquake-induced ground liquefaction susceptibility for Hanoi city using geological and geomorphologic characteristics

In this paper, the earthquake-induced liquefaction susceptibility of Hanoi city is assessed using the recent published geological and geomorphologic data. A combination of classification methods based on the distribution of sedimentary deposits proposed by Youd and Perkins (1978) and geomorphologic units proposed by Iwasaki (1982) was applied. The subsurface lithology and geomorphologic maps were combined in a GIS platform for assessing the liquefaction susceptibility of Hanoi city.The resulting map shows that the liquefaction hazard of Hanoi city classified into four categories: high, moderate, low liquefaction potential and not likely areas. In the most of Hanoi area, the ground liquefaction potentials are moderate. The high liquefaction likely areas spread along the river beds and around the lake areas. The not likely and low liquefaction potential areas are observed mainly in the northwest and northeast of the study region such as Chanchim, Soc Son, and Bavi mountains. The present map can help the scientists, engineers, and planners to have the general information on regional liquefaction potential of the Hanoi city. ReferencesBird JF, Bommer JJ, 2004b.
