Abstract

Purpose

The purpose of this paper is to propose a new algorithm for independent navigation of unmanned aerial vehicle path planning with fast and stable performance, which is based on pigeon-inspired optimization (PIO) and quantum entanglement (QE) theory.

Design/methodology/approach

A biomimetic swarm intelligent optimization of PIO is inspired by the natural behavior of homing pigeons. In this paper, the model of QEPIO is devised according to the merging optimization of basic PIO algorithm and dynamics of QE in a two-qubit XXZ Heisenberg System.

Findings

Comparative experimental results with genetic algorithm, particle swarm optimization and traditional PIO algorithm are given to show the convergence velocity and robustness of our proposed QEPIO algorithm.

Practical implications

The QEPIO algorithm hold broad adoption prospects because of no reliance on INS, both on military affairs and market place.

Originality/value

This research is adopted to solve path planning problems with a new aspect of quantum effect applied in parameters designing for the model with the respective of unmanned aerial vehicle path planning.

Abstract

Purpose

Banks are the major suppliers of external funds for companies in China. The purpose of this paper is to examine whether Chinese banks exercise effective monitoring over borrowers in two lending decisions, including loan interest rates and loan renewals.

Design/methodology/approach

Using a sample of Chinese public industrial firms from 2000 to 2005, the authors perform multivariate regression analysis to investigate whether banks adjust their loan interest rates and consider loan renewal decisions in response to borrowers financial performance. The authors also examine these bank lending decisions before and after 2003, when the major banking reforms started to take place in China.

Findings

A negative relation was found between the loan interest rate spread and the financial performance of borrowers. However, a negative relation was found between loan renewals and the financial performance of borrowers, consistent with firms in financial difficulties being in need of more funding and hence more likely to get its bank loans renewed. Additionally, it was found that the factors banks consider when making loan decisions vary before and after 2003.

Originality/value

The authors' findings suggest that Chinese banks play a limited role in monitoring and disciplining borrowers through adjustments of loan interest rates, and that their loan renewal decisions for firms with poor financial performance highlight banks' financing, instead of monitoring role in this transition economy. These findings provide empirical evidence on bank governance in a transition economy dominated by state‐owned enterprises. The paper contributes to the literature by constructing an alternative loan renewal measure using financial statement information.

Abstract

The accelerating process of economic globalization and the increasingly fierce international competition are conducive to the promotion of the construction of the urban regional innovation system. Based on this, the Bayesian discriminant model was established in this paper, and the development stage of the regional innovation system was prejudged. Then according to the discriminant analysis, the results of the pre judgment were tested. In addition, based on the innovation system of urban planning and construction, a framework of urban planning analysis based on regional innovation system was put forward, which was used to guide regional planning and implementation, and was applied to the planning of Shanxi science and technology innovation city. It is proved that the fuzzy evaluation system based on Bayes is beneficial to the innovative planning of the new city.

Abstract

Purpose

Parameter identification is an important issue in structural health monitoring and damage identification for concrete dams. The purpose of this paper is to introduce a novel adaptive fireworks algorithm (AFWA) into inverse analysis of parameter identification.

Design/methodology/approach

Swarm intelligence algorithms and finite element analysis are integrated to identify parameters of hydraulic structures. Three swarm intelligence algorithms: AFWA, standard particle swarm optimization (SPSO) and artificial bee colony algorithm (ABC) are adopted to make a comparative study. These algorithms are introduced briefly and then tested by four standard benchmark functions. Inverse analysis methods based on AFWA, SPSO and ABC are adopted to identify Young’s modulus of a concrete gravity dam and a concrete arch dam.

Findings

Numerical results show that swarm intelligence algorithms are powerful tools for parameter identification of concrete structures. The proposed AFWA-based inverse analysis algorithm for concrete dams is promising in terms of accuracy and efficiency.

Originality/value

Fireworks algorithm is applied for inverse analysis of hydraulic structures for the first time, and the problem of parameter selection in AFWA is studied.

Abstract

Purpose

This paper aims to reveal the influencing mechanism of the interaction between institutional environments in the home and host country on the accelerated internationalization of entrepreneurial enterprises from emerging economies (EE). The authors want to open the black box of home-country institutional environments’ moderating mechanism on the relationship between host-country institutional environments and accelerated internationalization.

Design/methodology/approach

The authors chose a massive interview method and case study method to answer this question. According to our standards, the authors chose four high-tech companies in Guangdong and Guangxi provinces as case study samples. During investigation in the four case companies, the authors collected print data of 150 pages and electric data of 3 pages. Then, the authors excavated concepts in data through open coding, axial coding and select-type coding and identified concepts’ dimensions and connections between them.

Findings

Well-developed home-country institutions can reduce the inhibitory effect of under-developed host-country institutions on the accelerated internationalization of entrepreneurial enterprises from emerging economies. Under-developed institutional environments in the home country are beneficial for entrepreneurial enterprises from EE to develop the institutional capability for entrepreneurial enterprises with stronger institutional capability from emerging economies. The inhibitory effect of under-developed institutional environments in the host country on their accelerated internationalization is weaker. The positive moderating role played by institutional voids in the home country on the relationship between institutional voids in the host country and the accelerated internationalization are mediated by the institutional capability of entrepreneurial enterprises from emerging economies.

Research limitations/implications

The authors just refined the definition of institutional capability and divided its dimensions. Issues such as operationalization of institutional capability and the development of measurement scale are also worthy for future quantitative research. Considering the inherent defect of case study and that these four case companies are from Chinese high-tech industry, the external validity our research may be limited. The theoretical model that was constructed generally captured the relationships between dual institutional environments, institutional capability and EE entrepreneurial firms’ accelerated internationalization decision. Future studies may use a large-scale sample to verify the all propositions the authors introduced to draw more steady and reliable empirical study results.

Practical implications

The conclusions have significant implications for governments in EE to construct friendly institutional environments for international entrepreneurship and for entrepreneurial firms to implement internationalization strategies.

Social implications

Policy makers should establish well-developed normative and cognitive institutional environment by cultivating global-orientated and open national culture and organizing experience exchange conference, thereby speeding up the implementation of internationalization strategies and further improving international competitiveness for a country.

Originality/value

First, the authors defined institutional capability as firms’ ability of establishing relationships with institution actors, adapting to institutional contexts, changing existing institutions or creating new ones to gain potential interests and suggested that it consists of three dimensions. Second, institutional voids in the home country positively moderate the relationship between under-developed institutional environments in the host country and the accelerated internationalization of entrepreneurial firms from EE. At last, institutional capability of firms negatively moderates the relationship between under-developed institutional environments in the host country and the accelerated internationalization of entrepreneurial firms from EE.

Abstract

Purpose

Justice, although well developed in the organisational field, has not been given adequate attention in the area of construction project dispute negotiations. Based on previous studies, the purpose of this paper is to more elaborately discuss whether each dimension of justice (distributive, procedural and interactional) is important for negotiators to cooperate in construction project dispute negotiation and whether their impact was moderated by the completeness of construction contract.

Design/methodology/approach

A survey of 164 prime negotiators from different construction projects was conducted. A stepwise multiple regression was employed to test the impact of each dimension of justice, and then a moderated multiple regression model was used to test the moderating effect of contract completeness.

Findings

The results indicated that, while distributive justice is related to cooperative behaviours, the impact of procedural justice and interactional justice also have great impact, and even more significantly related to cooperative behaviours. Moreover, while contractual obligatoriness positively moderates the relationship between procedural justice and cooperative behaviours, the term specificity negatively moderates the relationship between procedural and interactional justice and cooperative behaviours.

Research limitations/implications

First, the authors aimed to test the effect of justice on cooperative behaviours in construction dispute negotiations originally, but did not determine whether their relationship is mediated by any other factors. Second, contractual governance was chosen as the moderator; other factors may also influence behaviours in project dispute negotiations.

Practical implications

First, project dispute negotiators should not focus their attention solely on the distribution of the negotiation issues. For a cooperative approach, negotiators should also give strong consideration to whether their offers reflect procedural justice and whether their opponents are being treated fairly. Second, while contractual design may affect the frame surrounding the negotiations to help negotiators achieve an integrated outcome, they should give more attention to certain forms of justice.

Originality/value

In contrast to previous studies, the authors defined all three forms of justice in project dispute negotiations, and by adding all three forms of justice into the model, the authors attempted to investigate whether distributive, procedural and interactional justice were all related to cooperative behaviours in project dispute negotiations and to ascertain the extent to which each form of justice is important. Furthermore, the authors explored variations in the importance of each form of justice in negotiations under different contractual conditions.

Abstract

Purpose

The purpose of this paper is to examine the harmful effect of abusive supervision on employee creativity through feedback-seeking behavior (FSB) and the moderation of this mediation by proactive personality.

Design/methodology/approach

This study conducted hierarchical regression and path analysis to analyze the 341 manager–employee dyads data gathered from 11 companies in China.

Findings

The results reveal that abusive supervision had a detrimental effect on employee creativity partially mediated by employee FSB, and employees' proactive personality moderated the mediation.

Research limitations/implications

Although the findings of this research are based on multiple sources data, it is hard to draw causal inferences because the nature of the data is cross-sectional.

Practical implications

Organizations should be aware of the deleterious effect of abusive supervision on employee creativity and should seek to inhibit supervisors' abusive behavior in the workplace.

Originality/value

This study re-examines the relationship between abusive supervision and employee creativity in the Chinese context from the social exchange perspective. The mediating role of FSB and the moderating role of proactive personality offer new insights in-to the mechanisms and boundary conditions associated with the relationship between abusive supervision and employee creativity.

Abstract

Purpose

This paper aims to explore the complete process and underlying mechanism that social enterprises obtain legitimacy during interactions with stakeholders from theoretical integration of institutional theory and organization ecology perspective.

Design/methodology/approach

Based on theoretical classification, this paper selects six typical Chinese social enterprises and conducts a multi-case analysis.

Findings

The study finds that social enterprises aim at legitimizing single entity or industry and shaping stakeholders’ cognitive boundary simultaneously. Therefore, by adopting constrained cooperation and competition activities, social enterprises use normative isomorphism to achieve personal legitimation and combining ecological niche construction, social enterprises achieve organizational legitimation. By adopting fragmented cooperation-dominant or competition-dominant activities, social enterprises use mimic isomorphism supplemented by competitive isomorphism or population structure creation to obtain industry legitimation. By adopting dynamically integrated coopetition activities, social enterprises use mimic isomorphism and reflexive isomorphism to reach field legitimation.

Originality/value

This paper proposes a mechanism model that the coopetition with stakeholders influences the legitimation process, identifies four stages of social enterprise’s legitimation process and the types of legitimacy obtained in each stage and fills the gap of Chinese indigenous social enterprise research.

Abstract

Purpose

The reviews submitted by users are the foundation of user-generated content (UGC) platforms. However, the rapid growth of users brings the problems of information overload and spotty content, which makes it necessary for UGC platforms to screen out reviews that are really helpful to users. The authors put forward in this paper the factors influencing review helpfulness voting from the perspective of review characteristics and reviewer characteristics.

Design/methodology/approach

This study uses 8,953 reviews from 20 movies listed on Douban.com with variables focusing on review characteristics and reviewer characteristics that affect review helpfulness. To verify the six hypotheses proposed in the study, Stata 14 was used to perform tobit regression.

Findings

Findings show that review helpfulness is significantly influenced by the length, valence, timeliness and deviation rating of the reviews. The results also underlie that a review submitted by a reviewer who has more followers and experience is more affected by review characteristics.

Originality/value

Previous literature has discussed the factors that affect the helpfulness of reviews; however, the authors have established a new model that explores more comprehensive review characteristics and the moderating effect reviewer characteristics have on helpfulness. In this empirical research, the authors selected a UGC community in China as the research object. The UGC community may encourage users to write more helpful reviews by highlighting the characteristics of users. Users in return can use this to establish his/her image in the community. Future research can explore more variables related to users.

Abstract

Purpose

The purpose of this paper is to investigate the effect of pulsed magnetic field (PMF) with different duty cycles on the melt flow and heat transfer behaviors during direct-chill (DC) casting of large-size magnesium alloy billet and find the appropriate range of duty cycle.

Design/methodology/approach

A transient two-dimensional mathematical model coupled electromagnetic field, flow field and thermal field, is conducted to study the melt flow and temperature field under PMF and compared with that under the harmonic magnetic field.

Findings

The results reveal that melt vibration and fluctuation are generated due to the instantaneous impact of repeated thrust and pull effects of Lorentz force under PMF. The peak of Lorentz force decreases greatly with the increasing duty cycle, but the melt fluctuation region is expanded with higher duty cycle, which accelerates the interior melt velocity and reduces the temperature gradient at the liquid-solid interface. However, PMF with overly high duty cycle has adverse effect on the melt convection and limited influence on the interior melt. A duty cycle of 20% to 50% is a reasonable range.

Practical implications

This paper can provide guiding significance for the setting of duty cycle parameters on DC casting under PMF.

Originality/value

There are few reports on the effect of PMF parameters during DC casting with applying PMF, especially for duty cycle, a parameter unique to PMF. The findings will be helpful for applying the external field of PMF on DC casting.
