Abstract
This chapter highlights the characteristics of Asia through the analysis of policy-related documents by five donor countries, namely Japan, South Korea, China, India and Thailand. It will also examine the roles played by regional bodies such as the Southeast Asian Ministers of Education Organization (SEAMEO) and ASPBAE (the Asia South Pacific Association for Basic and Adult Education) as the horizontal channels influencing aid policies in respective countries. Together with the analysis of the national and organizational policies, the regional process of building consensus on the post-2015 agenda is examined, with a particular focus on the Asia-Pacific Regional Education Conference (APREC) held in August 2014.
The analysis reveals that the region has two faces: one is imaginary and the other is functional. There is a common trend across Asian donors to refer to their historical ties with regions and countries to which they provide assistance and their traditional notions of education and development. They highlight Asian features in contrast to conventional aid principles and approaches based on the Western value system, either apparently or in a muted manner. In this sense, the imagined community of Asia with common cultural roots is perceived by the policymakers across the board.
At the same time, administratively, the importance of the region as a stage between the national and global levels is recognized increasingly in the multilateral global governance structure. With this broadened participatory structure, as discussed in the chapter ‘Post-EFA Global Discourse: The Process of Shaping the Shared View of the ‘Education Community’’, the expected function of the region to transmit the norms and requests from the global level and to collect and summarize national voices has increased.

Abstract
Purpose
The paper aims to propose a virtual reality (VR) wisdom teaching model in open university English course from the perspective of “Metaverse”. The study aims to testify the stimulation for English learning and the effectiveness of English-expressing with VR tools for adult learners from the practice in a pilot reform project.
Design/methodology/approach
The paper opted for an exploratory study using ICARE Design Model as the framework, under the grounded theories of constructivism and multi-modal teaching. The study compared the evaluation data of one-semester English learning performance between the experimental class (67 students) with VR practice and the controlled class (67 students), including speaking test score, qualitative feedback and in-depth experience analysis. The data were complemented by reflection paper analysis, including manual evaluation (the criteria of semantics, pronunciation, fluency and completeness), questionnaire survey (in the form of five-point Likert scale) and semi-structured interview.
Findings
The paper provides empirical insights about the VR wisdom teaching model in English language teaching and learning in a Chinese Open University. The empirical results suggest that “3I” features of VR technology could make up for the shortcomings of traditional English classes in open universities in China, and VR resources designed with curriculum teaching materials could also be helpful for students’ command of knowledge points and language skills. What’s more, the sense of authentic experience in virtual could promote the teaching and learning effect in college English classes.
Research limitations/implications
The present study focuses on a wisdom mode of foreign language teaching and learning for adult learners in open education, so the research results may lack generalizability. Therefore, researchers are encouraged to further explore the deep integration of VR/artificial intelligence in foreign language teaching and learning.
Originality/value
This paper fulfills an identified need to study how VR tools provide an engaging, fun and immersive language learning environment, to enhance autonomous learning and learning engagement.

Abstract
Purpose
The purpose of this paper is to research the impact of hybrid series‐parallel and parallel‐series system configurations on system performances based on system reliability and to develop a configuration model to meet the requirement of reconfigurable manufacturing system (RMS).
Design/methodology/approach
Based on the criterion of system reliability, a RMS configuration model is presented – the hybrid parallel‐series model with waiting system characteristics. The configuration model is evaluated from reliability, productivity, and cost by combining system engineering theory, Boolean algebra methodology with statistical analysis theory. The model reliability has been used to ameliorate by adopting the integrated algorithm based on Shrama and Misra optimization algorithm.
Findings
The need for application of this method and model – some constraints must be limited, the hybrid parallel‐series configuration is superior and the integrated algorithm is effective to RMS system configuration.
Research limitations/implications
Cost constraints, equipment weight constraints, and function independency of equipment are main limitations.
Practical implications
The model and method have been used to ameliorate the reconfigurable automobile parts product line in SH automobile motor company of Shanghai. The operation result illustrates the validity of this configuration model and algorithm.
Originality/value
The new RMSs configuration model has been proposed. The new algorithm is proposed to ameliorate and optimize a reconfigurable product line with the integrated algorithm based on Shrama and Misra algorithm. The actual running effect is significant.

Abstract
Purpose
The unitized curtain wall system (UCWS), a symbol of modern architecture, is gaining popularity among prefabricated components. Previous studies have focused on both construction technology advances and material selection strategies to facilitate the UCWS. However, the topic of client satisfaction, which drives industry development by targeting clients' demands, has gone unnoticed. Therefore, the current study aims to investigate client satisfaction with UCWS products in Hong Kong by finding its influential factors.
Design/methodology/approach
A systematic review was employed to first identify the influential factors. A semi-structured interview was employed to validate the reliability of the extracted factors. The machine learning algorithm Extreme Gradient Boosting (XGBoost) and the Pearson correlation were then employed to rank the importance and correlation of factors based on the 1–5 Likert scale scores obtained through a questionnaire survey.
Findings
The findings revealed that “reduction in construction time” and “reduction in construction waste” are the most important factors and have a strong positive influence on client satisfaction.
Originality/value
Unlike previous studies, the present study focused on a novel research topic and introduces an objective analysis process using machine learning algorithms. The findings contribute to narrowing the knowledge gap regarding client preference for UCWS products from both individual and collaborative perspectives, providing decision-makers with an objective, quantitative and thorough reference before making investments in the curtain wall management development.

Abstract
Purpose
The purpose of this study is to present the state of the art for fiber Bragg grating (FBG) acceleration sensing technologies from two aspects: the principle of the measurement dimension and the principle of the sensing configuration. Some commercial sensors have also been introduced and future work in this field has also been discussed. This paper could provide an important reference for the research community.
Design/methodology/approach
This review is to present the state of the art for FBG acceleration sensing technologies from two aspects: the principle of the measurement dimension (one-dimension and multi-dimension) and the principle of the sensing configuration (beam type, radial vibration type, axial vibration type and other composite structures).
Findings
The current research on developing FBG acceleration sensors is mainly focused on the sensing method, the construction and design of the elastic structure and the design of a new information detection method. This paper hypothesizes that in the future, the following research trends will be strengthened: common single-mode fiber grating of the low cost and high utilization rate; high sensitivity and strength special fiber grating; multi-core fiber grating for measuring single-parameter multi-dimensional information or multi-parameter information; demodulating equipment of low cost, small volume and high sampling frequency.
Originality/value
The principle of the measurement dimension and principle of the sensing configuration for FBG acceleration sensors have been introduced, which could provide an important reference for the research community.

The purpose of this paper is to investigate the effects of electric current stressing on damping properties of Sn5Sb solder.
Abstract
Purpose
The purpose of this paper is to investigate the effects of electric current stressing on damping properties of Sn5Sb solder.
Design/methodology/approach
Uniformly shaped Sn5Sb solders were prepared as samples. The length, width and thickness of the samples were 60.0, 5.0 and 0.5 mm, respectively. The damping properties of the samples were tested by dynamic mechanical analyzer with a cooling system to control the test temperature in the range of −100 to 100°C. Simultaneously, electric current was imposed to the tested samples using a direct current supply. After tests, the samples were characterized using scanning electron microscope, electron backscatter diffraction and transmission electron microscope, which was aimed to figure out the damping mechanism in terms of electric current stressing induced microstructure evolution.
Findings
It is confirmed experimentally that the increase in damping properties is due to Joule heating and athermal effects of current stressing, in which Joule heating should make a higher contribution. G–L theory can be used to explain the damping properties of strain amplitude under current stressing by quantitative description of geometrically necessary dislocation density. While the critical strain amplitude and high temperature activation energy decrease with increasing electric current.
Originality/value
These results provide a new method for vibration reliability evaluation of high-temperature lead-free solders in serving electronics. Notably, this method should be also inspiring for the mechanical performance evaluation and reliability assessment of conductive materials and structures serving under electric current stressing.

The purpose of this paper is to focus on finding the optimal maintenance interval and the minimum maintenance cost for redundant system, considering environment factors.
Abstract
Purpose
The purpose of this paper is to focus on finding the optimal maintenance interval and the minimum maintenance cost for redundant system, considering environment factors.
Design/methodology/approach
The authors propose a decision model with environment-based preventive maintenance for the repairable redundant system. Referring to the k-out-of-n model and Proportional Hazard Model, the reliability analysis is completed for the redundant system affected by internal and external issues. Meanwhile, the maintenance cost for the redundant system is divided into two categories: the fixed maintenance cost involving whole system replacement at the time of system failure, and the cost to replace failure components when the system still functions.
Findings
Upon the required reliability analysis, an optimal maintenance interval that minimizes the average maintenance cost per unit time is identified. The simulation results indicate that the optimal maintenance interval with consideration of environmental factors is significantly shorter than that without consideration of these factors, with the maintenance cost increase within 10 percent.
Practical implications
The redundant systems have widely been used in industries including the aero craft control system and warship power system. The model could be applied in the more real case considering the types of components and the operation environment, and help production managers better maintain machines by increasing the safety and reliability of the redundant model with the more frequent inspection.
Originality/value
Previous research of redundant system always focuses on internal degradation, while ignoring the reliability analysis for a redundant system with various multiple components under the influence of environment. However, this work could fill the theoretical gap, i.e. simultaneously consider both environmental and internal factors for a redundant system with non-homogeneous components. Meanwhile, the proposed superior model increases the reliability and safety of the k-out-of-n model with reasonable cost. Production managers could benefit a lot from this as well.

Abstract
Purpose
The purpose of this paper is to review and compare the implementation of “arts inclusion” policies (AIPs) by 14 different public administrative systems around the world. It aims to provide a consolidated source which informs further studies in this field, and to develop a framework to compare AIPs at a global level.
Design/methodology/approach
Using “arts inclusion policy” as the search term, academic journals from a wide spectrum of fields were reviewed. A data set was extracted from the Compendium of Cultural Policies and Trends’ online database which provided real-time information of national cultural policies. Another data set is from the United Nations’ Inequality-adjusted Human Development Index, as the geographic scope of the review – largely focussing on UK, US, Australian, Scandinavian and Asian contexts. Using existing policy-making literature as benchmark, the authors designed and applied a comparative framework dedicated to AIPs which focussed on “policy-making structures” as the main ground of comparison.
Findings
An important finding is that the policy development and implementation of AIPs often underscore inter-sectoral involvement in many public administrations in this study. With policy leadership and financial incentives pivotal to effective AIPs, central governments should take a more concerted leadership role to include AIPs in national inter-sectoral policies, encourage evidence-based research, expand funding and advocate the recognition of the impacts of arts inclusion. It is concluded that AIPs in western countries remain more developed in targeted scopes and programme diversity compared to those of Asian countries and regions. Continued studies in this field are encouraged.
Originality/value
This review is the first of its kind to include a number of Asian and western countries within its research scope, allowing it to offer a more holistic outlook on the development and implementation of AIPs in different countries and regions. A common critique with all relevant existing literature was usually their lack of concrete comparative grounds, and the present study’s all-encompassing review of literature from across different levels and sectors of respective public administrative systems contribute to a unique and comprehensive perspective in the arts and health discourse.

Abstract
Purpose
This study aims to design and validate a theoretical model for capacitive imaging (CI) sensors that incorporates the interelectrode shielding and surrounding shielding electrodes. Through experimental verification, the effectiveness of the theoretical model in evaluating CI sensors equipped with shielding electrodes has been demonstrated.
Design/methodology/approach
The study begins by incorporating the interelectrode shielding and surrounding shielding electrodes of CI sensors into the theoretical model. A method for deriving the semianalytical model is proposed, using the renormalization group method and physical model. Based on random geometric parameters of CI sensors, capacitance values are calculated using both simulation models and theoretical models. Three different types of CI sensors with varying geometric parameters are designed and manufactured for experimental testing.
Findings
The study’s results indicate that the errors of the semianalytical model for the CI sensor are predominantly below 5%, with all errors falling below 10%. This suggests that the semianalytical model, derived using the renormalization group method, effectively evaluates CI sensors equipped with shielding electrodes. The experimental results demonstrate the efficacy of the theoretical model in accurately predicting the capacitance values of the CI sensors.
Originality/value
The theoretical model of CI sensors is described by incorporating the interelectrode shielding and surrounding shielding electrodes into the model. This comprehensive approach allows for a more accurate evaluation of the detecting capability of CI sensors, as well as optimization of their performance.
