Abstract

Purpose

The past 40 years of reform and opening up have seen the role of core competence receive unprecedented attention because of the impact of the new normal economy as well as the pressure of transformation and upgrading. Few Chinese enterprises have effectively constructed core competence, and there is also a lack of strategic perspective and contextual embedding of its construction process in theory. This study aims to analyse the unique contextual characteristics of China in the transitional period and the impact on the core competence construction of Chinese enterprises and proposes its construction mechanism for Chinese enterprises.

Design/methodology/approach

Through theoretical deduction and speculation, this paper analyses the process of concept formation, clarifies the concept, analyses its connotations and structure and emphasises its relativity. Based on a review of the theoretical research on the core competence construction process and an analysis of dual contextual impact, this paper puts forward a mechanism for core competence construction.

Findings

The results reveal that four specific characteristics of entrepreneurs in balancing and coping with the dual nature of external context constitute the key driving force for a Chinese enterprises’ core competence construction; under the influence of this driving force, the core competence construction mechanism includes process mode, knowledge source, management mode and key success factors.

Originality/value

Approaching it from a Chinese context, this study deepens the concept of core competence; enriches and develops the research related to the core strategic research proposition of its construction; and provides positive significance for Chinese enterprises to effectively build, develop and strengthen core competence and enhance their international competitiveness.

Abstract

Purpose

This paper explores the contextual factors involved in the development and application of paradigmatic theories in general, and the application and development of Agency Theory in the Chinese context in particular.

Design/methodology/approach

Referring to four templates for the design of conceptual papers as outlined by Jaakkola (2020), i.e. theory synthesis, theory adaptation, typology and model – we adopt an approach combining theory/literature synthesis and model establishment. Based on a thorough analysis and discussion of the literature on the topics of “context effect “, “interface between theory and context”, “special characteristics of Chinese context” and “invalid application of Agency Theory in a Chinese context”, we use Agency Theory as the lens to discuss the importance of context in applying and developing paradigmatic theory specifically. We start from the contextualization of Agency Theory and then explore approaches to theorizing the Chinese context by developing a conflict coefficient model.

Findings

First, the application validity of paradigmatic theories is not sustainable; contextual factors are critical in applying and developing not only propositional but also paradigmatic theories, such as Agency Theory. Second, the Chinese context requires special attention when applying paradigmatic theories originating from Western countries. Third, the traditional application logic of Agency Theory is invalid in the Chinese context due to the coexistence of principal-agent conflicts (PAC) and principal–principal conflicts (PPC), and changeable dominance status of two conflicts according to the contexts. Based on these observations, a model of contextualization theory of PAC and PPC (i.e. conflict coefficient model) is developed from a dynamic perspective, which connects the separated situation states and allows the identification and measurement of the relative severity of the two types of agency conflicts.

Practical implications

Practitioners can also use this model to identify and measure the relative strength of the two conflicts and determine the direction of control and improvement. Moreover, analysis of Chinese context and agency problems of Chinese firms also has great practical significance considering the increased importance of the Chinese market and the increasingly important role played by Chinese firms in the international economy in general, and in specific host countries in particular.

Originality/value

First, in general, this study expands Whetten's (2009) study of the interface between theory and context. It specifically discusses approaches to considering contextual factors in the development and application of the relatively overlooked paradigmatic theories, using traditional and widely used Agency Theory as a lens. Our study suggests that typical Agency Theory, developed based on Western-centric assumptions, does not completely hold in the context of Chinese business practices because of different cultural, legal and governance realities. Second, it improves and extends the application of Agency Theory by proposing the new perspective that PAC and PPC coexist in specific contexts and positing that the relative severity of two types of agency conflicts depends on the context variables. Third, it puts forward a conflict coefficient model offering a more comprehensive, intuitive and quantifiable method for comparing the extent of the two conflicts in different scenarios, providing a reference for empirical studies of corporate governance.

Abstract

Purpose

Many countries have a significant vaccination hesitancy rate regardless of vaccine prosperity. This study aims to identify factors restricting hesitancy and fostering vaccination intention and uptake against coronavirus in Vietnam.

Design/methodology/approach

The study has proposed an extended COM-B model based on the Theoretical Domains Framework to explore critical factors influencing vaccination intention and uptake in Vietnam. A database was collected from 1,015 suitable respondents who had received at least one dose of the COVID-19 vaccine, and ten hypotheses were tested by the partial least squares structural equation model.

Findings

The findings showed that six factors, including knowledge, experience, resource, social influence, belief and reinforcement, have either direct or indirect positive effects on COVID-19 vaccine uptake behavior. The output also indicated that personal experience positively affects vaccination intention and uptake.

Originality/value

This study contributes to understanding COVID-19 vaccine uptake behavior by identifying several direct and indirect factors of the extended COM-B model that include “knowledge” and “reinforcement” in shaping behavior change. The study adds to the literature on COVID-19 vaccine uptake behavior and could help achieve higher vaccination rates, ultimately leading to better control of the pandemic.

Abstract

Purpose

When a company practices greenwashing, it violates consumers' expectations by deliberately deceiving them about their environmental practices or the benefits of their products/services. This study investigated the effects of greenwashing on corporate reputation and brand hate. Furthermore, this study explored the mediating effects of perceived environmental performance and green perceived risk.

Design/methodology/approach

A survey design using cross-sectional primary data from 420 Portuguese consumers who identified and recognized brands engaged in greenwashing was employed. The proposed hypotheses were tested using structural equation modeling techniques.

Findings

This study's findings show that consumer perceptions of greenwashing may damage brands. The results show that greenwashing has a negative effect on corporate reputation through perceived environmental performance and green perceived risk. Additionally, greenwashing has a positive direct effect on brand hate and a negative effect on green perceived risk. Therefore, reducing greenwashing practices can improve consumers' perceptions of corporate environmental performance, buffer green perceived risk, and ultimately enhance corporate reputation. This can lead to positive relationships with customers.

Originality/value

Based on signaling and expectancy violation theories, this study develops a new framework highlighting the detrimental effects of greenwashing on brands. The combination of these theories provides the right framework to understand how greenwashing may lead to extreme feelings like brand hate and negative perceptions of corporate reputation, thus advancing the current research that lacks studies on the association between these constructs.

Abstract

Purpose

The qualitative approach was applied the discover the optimum answers to the research objectives, which are (1) to understand the cultural and hedonistic characteristics of the (Lanna) Songkran festival; and (2) to examine the dilemma between cultural rituals and hedonistic activity for tourism.

Design/methodology/approach

This study used a case study of the Songkran festival in Chiang Mai to examine the dilemma between cultural rituals and hedonism for tourism, which brings lost or misperceived cultural values and identities. The semi-structured interview (SSI) with senior locals and participant observation during the festival was conducted in Chiang Mai, Thailand, to obtain the in-depth phenomena of the existing celebration pattern at the festival.

Findings

The study findings show three crucial phenomena that explain characteristics of unsynchronized cultural rituals and hedonistic activities for tourism: (1) the parallel phenomenon between cultural values and celebration practice, (2) the movement of local culture and(3) the hedonistic characteristics of the festival.

Practical implications

The study extends the knowledge on the interplay phenomena between cultural festivals and tourism; also, the involved stakeholders, such as local communities, public sectors and private sectors, can use the study findings in creating policies for using cultural festivals to promote a destination and urban economic development that will minimise cultural values distort while increase tourism economic values.

Originality/value

This study was conducted qualitatively, including SSIs and participant observation at the Songkran festival in Chiang Mai. The study findings were analysed, based on the empirical data, into significant themes representing the characteristics of dilemma phenomena within the festival.

Abstract

Purpose

The purpose of this paper is to investigate factors influencing intent to adopt unmanned aerial vehicles for use in agricultural operations in Jilin Province, China.

Design/methodology/approach

This paper uses probit analysis to estimate the influence of factors on intent to adopt unmanned aerial vehicles for plant protection application operations in Jilin Province, China based on the Technology Acceptance Model.

Findings

UAV technology is acceptable to most participating farmers. Gender (male), agricultural income ratio, understanding of new technology, perceived ease-of-use and perceived usefulness have a positive relationship with farmers’ willingness to adopt UAVs.

Practical implications

For application, crop monitoring and other farm operations, UAVs have clear advantages. There remain challenges associated with the development of applicable technology and facilitating adoption among farmers. Understanding factors affecting adoption will contribute to the latter, and brings forth the following recommendations: conduct research on the cost effectiveness of UAVs for agriculture; accelerate development of the information service system; and increase financial support.

Originality/value

This paper is among the first to consider adoption intent among Chinese farmers of use of UAVs for agricultural operations.

Abstract

Purpose

The purpose of this paper is to investigate a Pb‐free solder alternative, specifically the effect of Bi on the microstructure and tensile strength of Sn‐3.7Ag solders casted under different cooling rates.

Design/methodology/approach

Sn‐3.7Ag solder paste was mechanically blended with different percentages of Bi particles (99.999 percent) to form composite solder pastes. The solder paste was cast under different cooling rates to form dog‐bone shape samples for tensile testing. The solder samples were subjected to tensile testing on an INSTRON 5543 tester with loading rate 10−3 s−1. Both the as‐cast and tensile‐tested samples were mounted, ground and polished for microstructure and fracture surface analysis. Scanning electron microscopy/Energy dispersive X‐ray spectroscopy was used to characterize the microstructure, morphology, and composition.

Findings

The tensile strength of Sn‐3.7Ag solder increased with increased Bi addition. However, elongation decreased with increased Bi addition. The tensile strength of Sn‐3.7Ag‐xBi (x=0, 1, 2, 3, 4 wt%) solders increased with increased cooling rates when Bi is lower than 3 wt%. The reason for improved strength of Sn‐3.7Ag‐xBi solders is the result of the combination of the solid solution strengthening and precipitation strengthening effects of Bi.

Originality/value

Tensile testing Bi reinforced Sn‐3.7Ag solder formed under different cooling rates is new in the paper. With the additions of Bi to Sn‐3.7Ag, the solder strength has been increased, which may be beneficial to the electronics industry and other researchers seeking a better replacement for Sn−Pb solder.

Abstract

Purpose

In order to solve the problem of inaccurate calculation of index weights, subjectivity and uncertainty of index assessment in the risk assessment process, this study aims to propose a scientific and reasonable centralized traffic control (CTC) system risk assessment method.

Design/methodology/approach

First, system-theoretic process analysis (STPA) is used to conduct risk analysis on the CTC system and constructs risk assessment indexes based on this analysis. Then, to enhance the accuracy of weight calculation, the fuzzy analytical hierarchy process (FAHP), fuzzy decision-making trial and evaluation laboratory (FDEMATEL) and entropy weight method are employed to calculate the subjective weight, relative weight and objective weight of each index. These three types of weights are combined using game theory to obtain the combined weight for each index. To reduce subjectivity and uncertainty in the assessment process, the backward cloud generator method is utilized to obtain the numerical character (NC) of the cloud model for each index. The NCs of the indexes are then weighted to derive the comprehensive cloud for risk assessment of the CTC system. This cloud model is used to obtain the CTC system's comprehensive risk assessment. The model's similarity measurement method gauges the likeness between the comprehensive risk assessment cloud and the risk standard cloud. Finally, this process yields the risk assessment results for the CTC system.

Findings

The cloud model can handle the subjectivity and fuzziness in the risk assessment process well. The cloud model-based risk assessment method was applied to the CTC system risk assessment of a railway group and achieved good results.

Originality/value

This study provides a cloud model-based method for risk assessment of CTC systems, which accurately calculates the weight of risk indexes and uses cloud models to reduce uncertainty and subjectivity in the assessment, achieving effective risk assessment of CTC systems. It can provide a reference and theoretical basis for risk management of the CTC system.
