Abstract

Purpose

Based on the model of Big-Five personality traits and theories of person–environment interaction, this study aims to investigate the moderating effects of personality traits on innovativeness through knowledge sharing (KS).

Design/methodology/approach

A sample of 318 Vietnamese employees was collected. The hypothesized model was tested by using partial least squares structural equation modelling.

Findings

The results indicate that extraversion, agreeableness, conscientiousness and openness to experience have relationships with innovativeness through the mediating effect of KS. Furthermore, transformational leadership (TL) mitigates the positive relationship between agreeableness and openness to experience and innovativeness.

Practical implications

Based on the research results, the authors suggest several practical implications for enhancing employees' innovative organizational behaviours. Transformational leaders should be aware of and control the relationships with employees high in agreeableness and open to experience to ensure that employees' innovativeness can be freely developed.

Originality/value

This research systematically investigates the effect of each personality on employees' innovativeness. Furthermore, this study contributes to the leadership literature by suggesting the dark side of TL that can negatively influence the innovative ability of employees with certain personality traits.

Abstract

Purpose

Compliant mechanism has been receiving a great interest in precision engineering. However, analytical methods involving their behavior analysis is still a challenge because there are unclear kinematic behaviors. Especially, design optimization for compliant mechanisms becomes an important task when the problem is more and more complex. Therefore, the purpose of this study is to design a new hybrid computational method. The hybridized method is an integration of statistics, numerical method, computational intelligence and optimization.

Design/methodology/approach

A tensural bistable compliant mechanism is used to clarify the efficiency of the developed method. A pseudo model of the mechanism is designed and simulations are planned to retrieve the data sets. Main contributions of design variables are analyzed by analysis of variance to initialize several new populations. Next, objective functions are transformed into the desirability, which are inputs of the fuzzy inference system (FIS). The FIS modeling is aimed to initialize a single-combined objective function (SCOF). Subsequently, adaptive neuro-fuzzy inference system is developed to modeling a relation of the main geometrical parameters and the SCOF. Finally, the SCOF is maximized by lightning attachment procedure optimization algorithm to yield a global optimality.

Findings

The results prove that the present method is better than a combination of fuzzy logic and Taguchi. The present method is also superior to other algorithms by conducting non-parameter tests. The proposed computational method is a usefully systematic method that can be applied to compliant mechanisms with complex structures and multiple-constrained optimization problems.

Originality/value

The novelty of this work is to make a new approach by combining statistical techniques, numerical method, computational intelligence and metaheuristic algorithm. The feasibility of the method is capable of solving a multi-objective optimization problem for compliant mechanisms with nonlinear complexity.

Abstract

Purpose

There is an increase globally of students using technology to support their learning. The purpose of this paper is to outline the technical aspects of adaptive learning and contribute to the development of pedagogy that incorporates this method in teaching and learning.

Design/methodology/approach

This is a technical review article that summarises key guidance on the application of adaptive learning and then reflects on its application in a UK and Vietnamese context.

Findings

Initial analysis demonstrates that learning can occur asynchronously because of students engaging with adaptive learning. Issues and recommendations were derived from the reflections and practice of both UK and Vietnamese practitioners. Recommendations focussed on the more practical elements of constructing and maintaining adaptive learning. Questions were then constructed to make the decision of whether to implement adaptive learning into teaching and learning practices.

Originality/value

This academic commentary reflects on the implementation of asynchronous learning adaptive technologies in both the UK and Vietnam, specifically exploring the use of a “mastery path” and “computerised adaptive testing” to enhance student understanding.

Abstract

Purpose

Digital technologies can enable engagement online as well as in physical infrastructures like large lecture theatres. Avoiding a tech-first approach to curriculum design, this article reviews a key resource for the use of a pedagogy-first, co-design approach in a specific instance of developing curriculum for connected learning at scale.

Design/methodology/approach

This article summarises key guidance for applying a co-design approach to a large educational transformation project (connected learning at scale) and reflects on the application in the UK (a developed economy) and in Vietnam (one of the fastest growing economies).

Findings

The guidance is found to reflect similar co-development processes in the UK and Vietnam, but adds additional layers of infrastructure and support to enable rich co-design processes. These are seen as proportionate given the impact of large-scale curricula.

Originality/value

This is the first time a review has been conducted from the perspective of different countries.

Abstract

Subject area

Decision-making seems simple, but, in reality, it is not an easy task to decide the cause for its profound result or consequence, leading to inevitable failures. Therefore, a leader must recognize whether there is something incorrect so as to avoid bad results. A good leader is a person who carefully reviews and analyzes aspects of a problem, knows the strengths and weaknesses of his organization and evaluates what the advantages or risks are. It cannot be denied that the appropriate options will reap many benefits to the business. For such important things, this paper will discuss the dilemma of Viettire, a tire distributor company in Vietnam. Accordingly, its CEO was worried about what strategic option he should adopt to approach the Myanmar market while ensuring a strategic fit to its company’s resources and capabilities and also to the overall market demands of the tire industry environment in both countries. However, with different ideas, the expansion strategies in this new market become controversial. The General Director and Founder of Viettire were wondering how Viettire could expand its existing business into Myanmar. To expand the company to new emerging market in Myanmar, Hoang Nguyen – CEO of Viettire – had conducted a strategic analysis of external environment factors to define the opportunities and threats when doing business in Myanmar by using Porter’s five forces model, S.W.O.T and competitive advantages analysis. The results indicated that Myanmar’s business environment is highly risky for foreign investors because of uncertain political, economic, social reforms in the process. Among three options, namely, exporting, licensing and wholly owned, however, Option 2 is illustrated as the best strategy for its dilemma.

Case overview

As for a market mechanism, what produces, how and for whom, is not the business’s demand but the consumer’s demand. The business sells only what the market needs, not what it has. In the period of increasingly competitive conditions, stabilizing and expanding markets are a prerequisite for survival. If stability is seen as a “defensive” way, expansion is a “defensive attack” like trying to hold on the “pie” that the market gives to itself. This strategic action is to strengthen regular, close relationships with existing customers and establish new customers. As a result, the potential market is transformed into a target market. Hence, decision-making of which market, which method is the issue that a leader has to think the choice to avoid risks. Mr Hung, Viettire’s co-owner, suggests that Myanmar should be taken into account as a company’s new entry, thus exploring this potential market to increase the company’s growth and profitability. In the progress, Viettire’s marketing team had been doing a thorough tire market investigation in Myanmar. It was concluded that this emerging country, especially Yangon City, was the most suitable for those who were willing to embark on an overseas investment expansion. They believe this was a good opportunity to gain market share compared with other entrants and competitive rivals; if Viettire hesitated to invest, others definitely had jumped in with a first-mover advantage. However, the CEO, Mr Hoang, was worried about what strategic option he should adopt to approach this new market while ensuring a strategic fit to its company’s resources and capabilities and also to the overall market demands of the tire industry environment in both countries.

Expected learning outcomes

Understand the basic decisions that firms contemplating foreign expansion must make: which markets to enter, when to enter those markets and at what scale. Recognize the current strategic decisions an organization is facing: positioning, portfolio and market expansion approach. Learn how to develop an effective strategic plan. Be familiar with different strategies for competing globally and their pros and cons. Evaluate various strategic options and decisions in accordance with a company’s resources and capabilities.

Abstract

Purpose

This study aims to understand pathways to success for food video bloggers (food vloggers) by identifying the drivers of positive reception among audiences. It examines how entertainment, information and interaction values affect attitudes toward food videos and vloggers. Additionally, it investigates the potential for product placement by studying the effects of attitudes toward food videos and vloggers on consumers’ behavioral intention regarding purchasing featured food ingredients.

Design/methodology/approach

An integrated model informed by theories (uses and gratification and stimulus-organism-response) was developed. An online survey was administered to 339 Vietnamese social media users. The data were analyzed using partial least square structural equation modeling (PLS-SEM).

Findings

The results show that food videos’ entertainment and information value positively impact the attitude toward food videos. However, the interaction value does not have a significant impact. All three values (entertainment value, information value and interaction) impact the attitude toward food vloggers. Both attitudes significantly influence purchase intention, showing that there is a pathway to product placement. The frequency of social media use can moderate these relationships, with a negative effect on the attitude toward food videos and a positive effect on the attitude toward food vloggers.

Originality/value

These findings provide insights into vlogger success pathways, not only in terms of audience reception but also in terms of product placement. This study offers comprehensive suggestions on pathways for success that are interesting for vloggers, food business operators, restaurant managers and audiences on how to design effective food videos and potentially encourage consumer purchases. These pathways can also be valuable for other behaviors, such as food safety advice and food waste reduction.

Abstract

Purpose

Pricing on the online booking systems is a difficult task for the host, the systems usually set the prices that are lower than the general premises and quality, and that only gives benefits to the system by easily attracting the customer to use the service. The setting price of the new accommodation is often based on location, the number of beds, type of house and so on. The main problem is to predict the most reasonable price for the host. This paper aims to study the use of machine learning and sentiment analysis for predicting the price of online booking systems.

Design/methodology/approach

In particular, an empirical study is performed first for some well-known classification models for the problems. The authors then propose to apply k-means, a clustering technique, together with Gradient Boost and XGBoost models to improve the prediction performance. Experiments are conducted and tested for real Airbnb data sets collected in London City.

Findings

Experimental results are given and compared to show that the authors’ method outperforms to an updated method.

Originality/value

The authors use k-means and sampling together with Gradient Boost and XGBoost models to improve the prediction performance.

Abstract

Purpose

One Commune One Product (OCOP) program, a rural economic development program in Vietnam, aims to empower local communities for sustainable social and economic welfare development, protect the environment and preserve tradition. This study aims to employ this program associated with tourism to support small family businesses in rural areas cost-effectively.

Design/methodology/approach

This study used the geographic location mapping method to design tourist routes that connect tourism resources with OCOP producers. A stakeholder approach was employed to identify suggested practical works that need to be implemented while developing this tourism initiative.

Findings

Four rural districts of Bac Giang Province, a northern province in Vietnam known as the place of various indigenous people live and traditional craft villages. Many cultural and historical tourist sites have been chosen as sample areas for this study. By using Google map, based on the Bac Giang Tourist Map and a list of recognized OCOP products in Bac Giang Province, main tourist sites (16 locations) and small family businesses (known as cooperatives and households) that have OCOP products (17 places) in the four districts have been identified. Four notable tourist routes have been formed to propose four thematic tours (two 1-day tours and two 2 days-1 night homestay tours). Suggestions for related stakeholders to ensure the sustainability of this initiative are provided.

Research limitations/implications

This study is supposed to be a model of promoting small family businesses through OCOP programs and tourism activities in a sustainable way in Vietnam. The outcome of this study is in line with the stakeholder theory emphasizing the systematic connection of various stakeholders such as employees, suppliers, local communities, government agencies and others towards complex business sustainability. The results of the study cannot conclude the small family businesses in Vietnam because it adopts geographic location mapping alone. Moreover, this study focused on OCOP programs only. Future research can use other methods of primary data collection, especially from tourists' perspectives. Data triangulation can be done to explore and verify the tourist routes that have been formed according to the four thematic tours proposed. Future research could also compare hotels managed by family businesses with non-family businesses.

Originality/value

This study is supposed to be a model of promoting small family businesses through OCOP programs and tourism activities in a sustainable way in Vietnam.

Abstract

Purpose

The purpose of this study is to show the presence of market discipline and provide an explanation for bank risk nondisclosure behavior, specifically market risk (MR), credit risk (CR), operational risk (OR) and counterparty credit risk (CCR). The response of market discipline when banks comply with Basel III capital and liquidity restrictions is also investigated in this study.

Design/methodology/approach

The study used the Lasso regression method to give accurate results with the lowest error when using small observational data with a large number of features.

Findings

First, theoretically, the study points to the presence of market discipline and its sensitivity to the risks disclosed by the bank, especially when applying capital regulations under Basel III. In addition, the study also shows differences between the developed and emerging countries in the sensitivity of market discipline to factors when considering banking regulations. Finally, an interesting result that the study shows is that the higher the index of economic freedom, the weaker the market discipline is, especially for emerging countries.

Practical implications

The study’s findings have several important implications: (1) help regulators devise policies to manage banks' risk and meet liquidity and capital requirements according to the Basel III framework. The effectiveness of market discipline is reduced, and banking regulators need to compensate by strengthening their supervisory functions. (2) Showed the reasons why banks ignore the disclosure of bank risks according to the provisions of the third pillar of the Basel III framework. Because when following the Basel III framework, depositors demand higher interest rates or increase market discipline towards riskier banks.

Originality/value

This study is the first attempt to assess market discipline under the new capital and liquidity regulations using the Lasso regression model as suggested by Tibshirani (1996, 2011), Hastie et al. (2009, 2015). This is also the first study to look at the impact of four different forms of risk on market discipline (as required by the Basel regulatory framework to improve disclosure).
