New Technology, Human Capital and Growth for European Transitional Economies.

We consider a transitional country with three sectors in economy: con- sumption goods, new technology, and education. Productivity of the con- sumption goods sector depends on new technology and skilled labor used for production of the new technology. Then there might be three stages of economic growth. In the first stage the country concentrates on produc- tion of consumption goods; in the second stage the country imports both physical capital and new technology capital; in the last stage the country imports new technology capital and invests in training and education of high skilled labor in the same time.Optimal growth model, New technology capital, Human Capital, Developing country.

New Technology, Human Capital and Growth in a Developing Country

In a developing country with three sectors: consumption goods, new tech- nology, and education, the productivity of the consumption goods depends on a new technology and skilled labor used to produce this new technology. There can be three stages of economic growth. In the …rst stage the country concentrates on the production of consumption goods; in the second the country must import both physical capital and new technology capital to produce consumption goods and new technology; in the third the country must import capital and invest in the training and education of high skilled labor.Optimal growth model; New technology capital;Human Capital; Developing country

Security for Multi-hop Communication of Two-tier Wireless Networks with Different Trust Degrees

Many effective strategies for enhancing network performance have been put forth for wireless communications' physical-layer security. Up until now, wireless communications security and privacy have been optimized based on a set assumption on the reliability or network tiers of certain wireless nodes. Eavesdroppers, unreliable relays, and trustworthy cooperative nodes are just a few examples of the various sorts of nodes that are frequently categorized. When working or sharing information for one another, wireless nodes in various networks may not always have perfect trust in one another. Modern wireless networks' security and privacy may be enhanced in large part by optimizing the network based on trust levels. To determine the path with the shortest total transmission time between the source and the destination while still ensuring that the private messages are not routed through the untrusted network tier, we put forth a novel approach. To examine the effects of the transmit SNR, node density, and the percentage of the illegitimate nodes on various network performance components, simulation results are provided

USING AUTHENTIC MATERIALS IN TEACHING SPEAKING TO GRADE 10 STUDENTS: TEACHERS’ PERCEPTIONS AND PRACTICES

Authentic materials are considered as a beneficial tool for teachers and students in teaching speaking English as a foreign language. Speaking is one of the most significant skills for EFL students to communicate with other peers. It is also important for tertiary students in the Vietnamese context. However, a few studies about the relationship between authentic materials and speaking ability were conducted in Vietnamese high school contexts. Therefore, the current study aimed to find out high school teachers’ perceptions and practices of using authentic materials in teaching English speaking to Grade 10 students in a Vietnamese context. Data collected in this study include questionnaire and semi-structured interviews. Participants in this study were seventy-seven high school teachers in five provinces in the Mekong delta. Findings from this study reveal that teachers had positive perceptions of using authentic materials in teaching English speaking to Grade 10 students. Pedagogical implications for teachers and school administrators are also made.  Article visualizations

THE RELATIONSHIP BETWEEN BILINGUALISM AND EMOTION PERCEIVED BY VIETNAMESE COLLEGE STUDENTS

Studies of the correlation between language and emotion have demonstrated the existence of a causal relationship between switching languages and feeling different in bi-/ multilinguals. Adopting the mixed-method approach, the current research aims to extend this line of enquiry to Vietnam – a monolingual country – by investigating 160 Vietnamese-English speaking students at International University (IU) (VNU-HCMC). They were required to complete a questionnaire based on the Bilingualism and Emotion Questionnaire (Dewaele & Pavlenko, 2001–2003). It includes closed questions concerning shifts on five scales of feelings and an open explanatory question on the difference perceived. The scales, chosen with reference to the research of Dewaele and Nakano (2012), consist of feeling logical, serious, emotional, fake, and different. Statistical analyses revealed a regular shift on most scales, with most participants feeling more logical, more serious, more fake, more different, and less emotional when using the L2. Simple linear regression revealed that the variation in certain feelings scales was mostly predicted by self-perceived proficiency in the L

Establishing an Assessment Criteria System for Architectural Heritage of Colonial Educational Buildings in Hanoi

A number of educational buildings were built up by the French in Hanoi during their dominance. Most of these buildings still exist in the downtown area and have become an integral part of the valuable heritage, and their preservation is increasingly imperative. To preserve and promote more efficiently the values of the colonial building heritage assets, there is a need of a set of criteria for an assessment and classification. This paper presents the development of an assessment criteria system for the architectural heritage of colonial educational buildings in Hanoi. According to the proposals, colonial educational buildings can be classified into three groups of Special Value, Notable Value, Average Value. A set of criteria including factors related to both the internal and external values of these buildings have been proposed and validated with expert judgements. Each criterion then is incorporated with a set of scores showing the value it can bring to a colonial educational building to be assessed. The set of criteria and their scores can be used by the city authority to establish regulations to preserve and promote heritage values of the colonial educational buildings in Hanoi

Security for Two-Way Untrusted Relay against Constant and Reactive Jamming with Fixed Signals

Active attacking in physical-layer security has not been significantly studied while potentially causing serious consequences for the legitimate networks. In this paper, we propose a novel method to estimate and remove the jamming signals from multiple multi-antenna jammers in a two-way relay network with multi-antenna legitimate and relay nodes. We carefully consider the signals in the time slots in order to exploit the repetition of the signals and design the transmitted signals which can work in different cases. The numerical results show that the secrecy maximum achievable sum-rate (MASR) at the legitimate nodes is higher than that of the conventional method when considering the affect of transmit SNR; the number antennas at the legitimate and relay nodes; normalized distance between one legitimate node and the relay; and the vertical coordinate of the relay

DOES DEMOGRAPHICS MATTER IN LIFELONG LEARNING? A RESEARCH CONTEXT OF VIETNAM

Objective: Lifelong learning (LLL) has lately attracted significant attention from the society in general, universities and corporations in particular. For the case of Vietnam, the Government has pledged to create a Lifelong Learning Society. A number of initiatives have been launched to help achieve this goal, including the Southeast Asian Ministers of Education Organization Centre for Lifelong Learning (SEAMEO CELLL) and "Book Day", a day dedicated to encouraging reading and raising awareness of its importance in the development of knowledge and skills. Lifelong learning (LLL) programs are also being adopted at libraries, museums, cultural centers, and clubs in Vietnam. In addition to the effort done by the Vietnamese government, a number of non-governmental, non-profit organizations and educational institutions have started to take action to encourage literacy and lifelong learning. It can be said that education and educational reforms are always the top concern of each country. This study is to investigate about lifelong learning of community with 4 aspects: (1) Learning Competencies; (2) Learning Contexts; (3) Learning Contents and (4) Learning Goals as well as examining the differences in the opinion about lifelong learning between categorical variables. The second purpose of the study is to examine the relationship between an individual's perspective on lifelong learning and their actual learning capacity, as well as learning motive. Methods: The paper deploys primary data collecting from 270 people in different sectors and different occupations. Standard statistical techniques such as mean analysis, OLS multivariable analysis are used to find the answer for proposed hypotheses. Results: Using a sample of 270 respondents varying in age, gender, and employment status, the authors found that there are differences on the attitudes towards lifelong learning, the motivations and skills needed for this “journey”. Conclusion: From the findings, researchers proposed recommendations to promoting and fostering lifelong learning of community with the case of Vietnam
