Abstract

Purpose

As small and medium-size enterprises (SMEs) rely on board heterogeneity to raise capital and establish credit relationships with suppliers, it is crucial to investigate the board heterogeneity effect on their survival. In this study, the first research objective is to provide further insights on the discriminatory power of survival approaches, specifically on semiparametric approaches in survival analysis that take into consideration both fixed and time-varying covariates. The second objective is to examine the relationship between board size and SME liquidation by using resource-based theories that focus on measuring board heterogeneity through board size.

Design/methodology/approach

This paper uses survival approaches for modelling SMEs survival by examining the survival of more than 68,000 SMEs in the UK covering the before, onset and post 2008 crisis periods and with firms’ demographic characteristics and financial indicators. Survival analysis is effective to examine multiple causes of default/failure and how do particular circumstances or characteristics increase or decrease the probability of survival. Survival analysis brings more advantages than linear-based regression approaches by effectively handling the censoring of observations.

Findings

Motivated by resource-based theories, the authors find that the likelihood of a firm being liquidated robustly increases with a reduction in its board heterogeneity measured through board size. This finding is held under non-parametric, parametric, and semiparametric approaches using survival analysis. The research shows better causal explanation and discriminatory power on using the semiparametric-based survival analysis approach considering both fixed and time-varying covariates.

Practical implications

This study demonstrates the better performance and causal explanation of the survival model using time-varying covariates compared with those using fixed covariates. In addition, the authors delve into board heterogeneity, measuring through the board size to investigate how the number of board directors affects the firm liquidation, it is also a factor worth considering when a small and medium firm is forming its board.

Originality/value

This research investigates the board heterogeneity effect on firm survival using survival analysis approaches. The authors contribute to the knowledge on board heterogeneity of SMEs. Specifically, the size of more than three directors could help reduce SMEs liquidation risk. This result gives a recommendation to firms or start-ups when forming their director board. This research also provides further insights on the applicability of survival models with unique UK SMEs data covering the before, onset and post 2008 crisis periods.

Abstract

Purpose

This paper aims to examine the influence of intrinsic motives (self-efficacy, reputation and reciprocity) on online knowledge sharing behaviour. Additionally, this research investigates the moderating role of individual innovation capability and top management support.

Design/methodology/approach

The methodology adopted was a questionnaire survey of employees working in Vietnamese telecommunications companies. A total of 501 employees completed a self-administered anonymous survey using a cross-sectional design. Confirmatory factor analysis and ordinary least squared – based hierarchical regression was used to test the conceptual framework.

Findings

Self-efficacy, reputation and reciprocity significantly impact online knowledge sharing behaviour. Specifically, self-efficacy has an inverted U-shape association while reputation and reciprocity have a positively, returns-to-scale association with online knowledge sharing behaviour. Individual innovation capability moderates the effect on these associations as does top management support, but to a lesser extent.

Research limitations/implications

Data were obtained at a single point in time and self-reported. Furthermore, this study was conducted in a specific industry in Vietnam, i.e. telecommunications, which limits the generalisability of the research.

Practical implications

Organisations need to create a favourable environment for online knowledge sharing to foster reciprocal relationships and interpersonal interactions of employees. Encouraging and rewarding employees to actively engage in knowledge exchange will help facilitate reciprocal online knowledge sharing behaviour.

Originality/value

This study contributes to knowledge-sharing behaviour by uncovering an inverted U-shape association and positively, returns-to-scale associations between intrinsic antecedents and online knowledge sharing behaviour. Additionally, individual innovation capability was an important moderator which has been overlooked in past research.

Abstract

Purpose

The phase-field method of interfacial damage is used to simulate the damage in composite structures containing the brittle orthotropic materials and their interface.

Design/methodology/approach

In the brittle fracture modeling, the strain tensor is decomposed into positive and negative parts characterizing tension and compression behaviors. By requiring an elastic energy preserving transformation involving the elastic stiffness tensor, these two strain parts must satisfy the orthogonality condition in the sense that the elastic stiffness tensor responds as a metric. However, most of the recent phase-field methods for brittle fracture do not verify this orthogonality condition. Additionally, to describe the damage in structures with anisotropic phases, recent studies have used multiple phase-field variables, with each preferential orientation represented by a phase-field variable to describe the bulk damage of component materials. This approach increases the complexity of simulation procedure. These disadvantages motivate the present study aimed at enhancing the simulation method.

Findings

The present study improves the phase-field method of interfacial damage by (1) incorporating the strain orthogonality condition into the phase-field method; (2) using only one phase-field variable instead of multiple phase-field variables to simulate damage in component orthotropic phases; and (3) investigating the interaction between interfacial damage and bulk damage as well as the effect of orientation tensor of preferential orientation in each orthotropic phase and the interfacial parameters on crack branching in composite structures.

Originality/value

Through several simulation examples, the present simulation method is proven to be accurate, effective, and helps the simulation process simpler than previous relevant methods.

Abstract

Purpose

The consolidation behavior of prefabricated vertical drain (PVD)-installed soft deposits mainly depends on the PVD performance. The purpose of this study is to propose a numerical solution for the consolidation of PVD-installed soft soil using the large-strain theory, in which the reduction of discharge capacity of PVD according to depth and time is simultaneously considered.

Design/methodology/approach

The proposed solution also takes into account the general constitute relationship of soft soil. Subsequently, the proposed solution is applied to analyze and compare with the monitoring data of two cases, one is the experimental test and another is the test embankment in Saga airport.

Findings

The results show that the reduction of PVD discharge capacity according to depth and time increased the duration required to achieve a certain degree of consolidation. The consolidation rate is more sensitive to the reduction of PVD discharge capacity according to time than that according to the depth. The effects of the reduction of PVD discharge capacity according to depth are more evident when PVD discharge capacity decreases. The predicted results using the proposed numerical solution were validated well with the monitoring data for both cases in verification.

Research limitations/implications

In this study, the variation of PVD discharge capacity is only considered in one-dimensional consolidation. However, it is challenging to implement a general expression for discharge capacity variation according to time in the two-dimensional numerical solution (two-dimensional plane strain model). This is the motivation for further study.

Practical implications

A geotechnical engineer could use the proposed numerical solution to predict the consolidation behavior of the drainage-improved soft deposit considering the PVD discharge capacity variation.

Originality/value

The large-strain consolidation of PVD-installed soft deposits could be predicted well by using the proposed numerical solution considering the PVD discharge capacity variations according to depth and time.

Abstract

Purpose

This paper aims to investigate the conditional equicorrelation and cross-quantile dependence between the DeFi, European and GCC currency markets (Oman, Qatar, Bahrain, Kuwait, Saudi Arabia and the United Arab Emirates).

Design/methodology/approach

This study applies the GARCH-DECO model and cross-quantilogram framework.

Findings

The findings reveal evidence of weak and negative average equicorrelations between the examined markets through time, excluding the COVID-19 outbreak and Russia–Ukraine conflict, which is consistent with the literature examining relationships in different markets. From the cross-quantilogram model, the authors note that the dependence between DeFi, EURO and GCC foreign exchange rate markets is greatest in the short run and diminishes over the medium- and long-term horizons, indicating rapid information processing between the markets under consideration, as most innovations are transmitted in the short term.

Practical implications

For the pairs of DeFi and currency markets, the static and dynamic optimal weights and hedging ratios are also estimated, providing new empirical data for portfolio managers and investors.

Originality/value

To the best of the authors’ knowledge, this is one of the most important research looking into the conditional correlation and predictability between the DeFi, EURO and GCC foreign exchange markets. More importantly, this study provides the first empirical proof of the safe-haven, hedging and diversification qualities of DeFi, EURO and GCC currencies, and this work also covers the COVID-19 pandemic and the Russia–Ukraine war with the use of a single dynamic measure produced by the GARCH-DECO model. In addition, the directional predictability between variables under consideration using the cross-quantilogram model is examined, which can be capable of capturing the asymmetry in the quantile dependent structure. The findings are helpful for both policymakers and investors in improving their trading selections and strategies for risk management in different market conditions.

Abstract

Purpose

Given the importance of leadership practices and knowledge resources in fostering innovation capabilities of firms, the purpose of this study is to explore the influence of transformational leadership on exploitative and exploratory innovation via mediating role of knowledge management capability. This study also attempts to increase understanding of the appropriate mechanisms for firms to pursue innovation capability by examining the moderating mechanism of competitive intensity.

Design/methodology/approach

This study utilized the structural equation modeling and cross-sectional design to test hypotheses in the proposed research model using survey data collected from 351 participants in 120 manufacturing and service firms.

Findings

The findings indicate that transformational leadership induces greater effect on exploratory innovation compared to its effect on exploitative innovation. The mediating role of knowledge management capability between transformational leadership and aspects of innovation capability is also supported. Especially, the influences of knowledge management capability on exploratory innovation capability are enhanced and depended on the degree of competitive intensity.

Research limitations/implications

Future research should examine the mediating mechanisms of knowledge acquisition, knowledge sharing and knowledge application to provide deeper insight on the role of specific components of knowledge management capability in linking transformational leadership and innovation capability.

Practical implications

The paper highlights the important role of transformational leadership practices for fostering knowledge management capability and specific aspects of innovation capability under high level of competitive pressure.

Originality/value

The paper is unique in the attempts to provide a prospective solution for firms to pursue and improve innovation based on the meaningful insights on the mediating role of knowledge management capability and moderating effect of competitive intensity in the relationship between transformational leadership and specific dimensions of innovation capability.

Abstract

This chapter describes how public sector reform (PSR) became important following the ‘Doi Moi’ (renovation) programme in 1986. Restructuring of state-owned sector was regarded as crucial for ensuring the quality of economic growth, and the Vietnamese government (www.chinhphu.vn/portal/page/portal/English) put considerable effort in PSR. The 8th Party Congress (1996) emphasized the urgent need for a more transparent, capable and modern public sector, including efforts to improve law-making process and capacity, reducing burdensome bureaucracy, fighting corruption, increasing leadership by senior officials and improving public service delivery. The government specifies the national PSR Master programme, and the Ministry of Home Affairs coordinates its implementation among ministries, central agencies and provincial governments. Local political leaders (party leaders) determine reforms based on guidelines of the party and government. The author writes that in spite of ambitious public service reform programmes and some positive achievements, the quality of public sector remains poor. The professional capacity of civil service is low, pay is low, corruption is high and processes and structures seem ill-fitted for the market economy. Reform scope is too broad, the capacity of public agencies and civil servants is limited and existing monitoring, evaluation and reporting systems are weak. In some successes, leaders use appointment and promotion to encourage lower level to implement reforms and training to increase understanding. They believe that Vietnamese leadership has become less proactive and vigorous in practicing or embracing bold reform experiments.

Abstract

“The world needs science, science needs women” is the message given by UNESCO in the program for the development of women in science” (UNESCO, 2017). In Vietnam, women’s participation and achievements in scientific research is considered a great and important resource for industrialization and modernization. Even so, are there gender differences in scientific achievement in the social science research institutes in Vietnam? What factors influence the scientific achievement of female social researchers? The answers will be based on data from a 2017 survey with a sample of 756 researchers, of which 77.6% were female. The survey was conducted by the Vietnam Academy of Social Sciences, a leading, ministry-level national center for the social sciences in Vietnam. This chapter analyzed the scientific achievements of researchers through their position as principal investigators of research projects and their publications, and factors that may impact this. Bivariate and multivariate analyses of factors that may affect the scientific achievement of researchers found that gender differences in academic achievement in the social sciences in Vietnam was still prevalent. Female researchers’ scientific achievements were lower than those of their male counterparts. The contribution to science of Vietnamese female researchers was limited by many different factors; the most important were the academic rank of the researchers and gender stereotype that considered housework the responsibility of women.

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 explore the pathway of increasing hotel booking intentions by mapping the linkage mechanism between the antecedents and components of brand equity to ultimately drive followers’ hotel booking intention. In addition, the role of over-endorsement as a moderating variable is also evaluated.

Design/methodology/approach

The conceptual model and research hypotheses were each assessed using covariance-based structural equation modeling. Paper-based and online surveys were used to collect data from 443 respondents who are TikTok users and follow at least one TikTok online celebrity, while that online celebrity must have reviewed at least one type of accommodation.

Findings

Except for the relationship between virtual interactivity and online celebrity brand image, the results confirmed the relationships between research concepts.

Research limitations/implications

Further studies are needed to validate the results in other cultural contexts, generalize findings and broaden the range of target respondents.

Originality/value

This study contributes to the hotel literature by illustrating how online celebrity brand equity (OCBE) drives hotel booking intentions. The study highlights the importance of antecedent factors – follower-centered drivers (e.g. lifestyle congruence, friendship) and online celebrity-led drivers (e.g. virtual interactivity, expertise) – to achieve a hierarchical relationship between OCBE components and followers’ booking intentions.
