Abstract

Purpose

The purpose of this paper is to explore the influence of PRINCE2 (PRoject IN Controlled Environments 2) standard on customer satisfaction jointly with vendor relationship management capability in the information technology outsourcing (ITO) context. This paper further tries to explore the above underlying mechanism by studying the mediating effect of deliverable quality.

Design/methodology/approach

This paper develops a mediated moderation model to explain the underlying influence processes of PRINCE2 standard, vendor relationship management capability and deliverable quality on ITO customer satisfaction. By conducting a pair-wise survey of 260 project managers in seven Iranian firms, the model and hypotheses are empirically tested with the partial least squares method.

Findings

Our results suggest that firms benefit more in terms of IT costs reduction when they have a higher level of complementary investment in an external standard, especially through an interplay effect of the external standard and internal relational aspect. Firms can make business processes more amenable to outsourcing and facilitate monitoring of vendor performance and effective coordination with vendors. More interestingly, we find that this interactive effect is fully mediated by deliverable quality, which, in turn, directly increases ITO customer satisfaction.

Originality/value

This study adds some new knowledge and provides new views to study ITO customer satisfaction by addressing the importance of PRINCE2 standard. This study further enhances our understanding in terms of the underlying pathway through which the PRINCE2 standard jointly affects customer satisfaction with vendor relationship management capability and deliverable quality. With the effort of explicitly explaining the complex mechanisms, this study helps ITO managers proactively escort outsourcing activities and projects.

Abstract

Purpose

The purpose of this paper is to explore the underlying mechanisms through which interactivity and fairness perception impart influence on solvers’ continuance intention in crowdsourcing contest settings.

Design/methodology/approach

On basis of self-determination theory and social exchange theory, this study focuses on the mediating roles of motivation and platform trust to explain the underlying influence processes of interactivity and fairness perception on continuance intention. A sample of 306 solvers was obtained from an online crowdsourcing platform through two separated surveys. The hypotheses were tested using the partial least squares method and bias-corrected bootstrapping method.

Findings

The empirical results indicate that motivation and platform trust together fully mediate the effect of interactivity on continuance intention, and the effect of fairness perception on continuance intention is also fully mediated by motivation and platform trust. While motivation is found to have a stronger mediating effect than platform trust does.

Originality/value

This study contributes to the crowdsourcing research by figuring out the pathway through which interactivity and fairness perception influence solvers’ continuance intention.

Abstract

Purpose

The purpose of this paper is to explore the underlying mechanisms through which integration capability and learning capability influence IT outsourcing performance from vendor’s perspective.

Design/methodology/approach

This paper develops a moderated mediation model to explain the underlying influence processes of integration capability and learning capability on vendor’s performance. A sample of 237 vendor firms was obtained from China through two separated surveys. The hypotheses were tested with the partial least squares method and bias-corrected bootstrapping method.

Findings

The empirical results indicate that external integration capability (EIC) mediates the effect of internal integration capability (IIC) on vendor outsourcing performance, and the relationship between EIC and vendor performance is positively moderated by learning capability, while learning capability has a negative moderating effect on the link between IIC and vendor performance. Further, the conditional indirect effect is suggested. The indirect effect of IIC on vendor performance through EIC becomes non-significant when learning capability is low.

Originality/value

This study highlights the counterintuitive notion that learning capability may not always have uniformly positive effects and figure out the mechanism through which integration capability and learning capability can effectively improve IT outsourcing performance.

Abstract

Purpose

This study aims to reveal the influencing factors of user churn behavior and explore how these factors influence user churn behavior of rural public digital cultural services (RPDCS), and then, to provide the avoidance strategies for user churn behavior of RPDCS.

Design/methodology/approach

Combined with the stimulus–organism–response theory and cognitive load theory, this study constructed a mixed model of user churn behavior. Data collected through online and offline questionnaire survey were tested using the partial least squares structural equation modeling approach, and finally, the authors proposed a user churn behavior model of RPDCS.

Findings

The results indicate that the environmental stimulus factors of RPDCS affected user churn behavior via user organism factors. This study suggests that administrators should pay more attention to the information demand of users and strengthen the effective supply of RPDCS. Meanwhile, it is necessary to improve the information literacy of rural users to restrain the user churn behavior and improve the effectiveness of RPDCS.

Originality/value

The research findings on the influencing factors of user churn behavior shed light on the user churn behavior in public digital cultural services, add new knowledge to the construction of the public cultural services system and provide empirical evidence for how to improve the utilization and effectiveness of RPDCS.

Abstract

Purpose

Online reviews increasingly present the characteristic of bidirectional communication with the advent of Web 2.0 era and tend to be asymmetrical and individualized in linguistic information. The authors aim to develop a new linguistic conversion model that exploits the asymmetric and personalized information from online reviews to express such linguistic information. A new online recommendation approach is provided.

Design/methodology/approach

The necessity of new linguistic conversation model is elucidated, and a leverage factor is incorporated into the linguistic label of negative review to handle the asymmetry problems of linguistic scale. A possible value range of the leverage factor is studied. A new linguistic conversation model is accordingly established with an unbalanced linguistic label and a cloud model. The authors develop a new online recommendation approach based on several modules, such as initialization, conversion, user-clustering and recommendation models.

Findings

The unbalanced effect between negative and positive reviews is verified with real data and measured using indirect methods. A new online recommendation approach of electronic products is proposed and used as an illustrative example to prove the practicality, effectiveness and feasibility of the proposed approach.

Research limitations/implications

Due to the unavailable transaction information of customers, the limitation of this study is the effectiveness of the authors’ established recommendation system for platform or website cannot be verified.

Originality/value

In most existing studies, the influence of negative review is counterbalanced by positive review, and the unbalanced effect between negative and positive reviews is ignored. The negative review receives much attention from consumers and businesses. This study thus highlights the influence of negative review.

Abstract

Purpose

Emissions produced by oceangoing vessels not only negatively affect the environment but also may deteriorate health of living organisms. Several regulations were released by the International Maritime Organization (IMO) to alleviate negative externalities from maritime transportation. Certain polluted areas were designated as “Emission Control Areas” (ECAs). However, IMO did not enforce any restrictions on the actual quantity of emissions that could be produced within ECAs. This paper aims to perform a comprehensive assessment of advantages and disadvantages from introducing restrictions on the emissions produced within ECAs. Two mixed-integer non-linear mathematical programs are presented to model the existing IMO regulations and an alternative policy, which along with the established IMO requirements also enforces restrictions on the quantity of emissions produced within ECAs. A set of linearization techniques are applied to linearize both models, which are further solved using the dynamic secant approximation procedure. Numerical experiments demonstrate that introduction of emission restrictions within ECAs can significantly reduce pollution levels but may incur increasing route service cost for the liner shipping company.

Design/methodology/approach

Two mixed-integer non-linear mathematical programs are presented to model the existing IMO regulations and an alternative policy, which along with the established IMO requirements also enforces restrictions on the quantity of emissions produced within ECAs. A set of linearization techniques are applied to linearize both models, which are further solved using the dynamic secant approximation procedure.

Findings

Numerical experiments were conducted for the French Asia Line 3 route, served by CMA CGM liner shipping company and passing through ECAs with sulfur oxide control. It was found that introduction of emission restrictions reduced the quantity of sulfur dioxide emissions produced by 40.4 per cent. In the meantime, emission restrictions required the liner shipping company to decrease the vessel sailing speed not only at voyage legs within ECAs but also at the adjacent voyage legs, which increased the total vessel turnaround time and in turn increased the total route service cost by 7.8 per cent.

Research limitations/implications

This study does not capture uncertainty in liner shipping operations.

Practical implications

The developed mathematical model can serve as an efficient practical tool for liner shipping companies in developing green vessel schedules, enhancing energy efficiency and improving environmental sustainability.

Originality/value

Researchers and practitioners seek for new mathematical models and environmental policies that may alleviate pollution from oceangoing vessels and improve energy efficiency. This study proposes two novel mathematical models for the green vessel scheduling problem in a liner shipping route with ECAs. The first model is based on the existing IMO regulations, whereas the second one along with the established IMO requirements enforces emission restrictions within ECAs. Extensive numerical experiments are performed to assess advantages and disadvantages from introducing emission restrictions within ECAs.

Abstract

Purpose

This paper aims to examine containership routing and speed optimization for maritime liner services. It focuses on a realistic case in which the transport demand, and consequently the collected revenue from the visited ports depend on the sailing speed.

Design/methodology/approach

The authors present an integer non-linear programming model for the containership routing and fleet sizing problem, in which the sailing speed of every leg, the ports to be included in the service and their sequence are optimized based on the net line's profit. The authors present a heuristic approach that is based on speed discretization and a genetic algorithm to solve the problem for large size instances. They present an application on a line provided by COSCO in 2017 between Asia and Europe.

Findings

The numerical results show that the proposed heuristic approach provides good quality solutions after a reasonable computation time. In addition, the demand sensitivity has a great impact on the selected route and therefore the profit function. Moreover, the more the demand is sensitive to the sailing speed, the higher the sailing speed value.

Research limitations/implications

The vessel carrying capacity is not considered in an explicit way.

Originality/value

This paper focuses on an important aspect in liner shipping, i.e. demand sensitivity to sailing speed. It brings a novel approach that is important in a context in which sailing speed strategies and market volatility are to be considered together in network design. This perspective has not been addressed previously.

Abstract

Purpose

This study aims to present a meta-analysis of the use of serious educational games in museums. The analysis is based on a critical literature review that maps educational roles of museums against serious educational games used in support of those roles. The meta-analysis focuses on the specific context of informal learning in museums.

Design/methodology/approach

The research design presented in this study is based on a meta-analysis research design that consists of a critical literature review, a multi-matrix representation of findings of the literature review and a conceptual visualization of the multidisciplinary area of the usage of serious games in support of educational roles in museums.

Findings

Clear and detailed categorizations of educational roles and serious games types for informal learning are presented. These are followed by matching these educational roles with published reports of the use of serious games within museums. The study concludes with observations and a conceptual map of the design of serious games for museums.

Originality/value

This study presents the first meta-analysis of research in this emergent multidisciplinary field. It will help serious game designers, museum educators and educational practitioners to make decisions regarding the choice of game type, customization and content design to support informal learning in the specific context of museum educational activities.

Abstract

Purpose

This paper aims to conduct a review on cruise shipping and the cruise shipping industry. The current trends are analyzed for the industry, showing that this industry is still young and has great potential to boom. Meanwhile, the Asia market is the fastest growth region among the global, to which increasing cruise ships are repositioned by major cruise lines. However, for such a promising industry, the literature review on some state-of-the-art research works suggests that the research works that have been conducted for the cruise shipping are quite limited, and the majority of the works belongs to empirical and descriptive studies, which does not provide optimization-based quantitative analysis on some operation planning problems.

Design/methodology/approach

This paper conducts a review on cruise shipping and the cruise shipping industry.

Findings

In reality, there are some important operation planning problems faced by cruise lines or cruise ships, and four of them are addressed in this paper in response to the fast growing trend. The addressed operation planning problems are cruise fleet management, cruise ship deployment, cruise itinerary design and cruise service planning.

Originality/value

The importance and the attention for the research on the problems are also elaborated in the paper.

Abstract

Purpose

The reported mathematical models of gas–liquid flow in single snorkel Rheinstahl–Heraeus (SSRH) are based on the assumption of steady Ar-molten steel flow. The purpose of this paper is to develop a mathematical model to describe the unsteady turbulent flow (CO-Ar-molten steel) with nonequilibrium decarburization reaction.

Design/methodology/approach

On the base of the finite volume method, the computational fluid dynamics software CFX is used to predict the unsteady fluid flow, the spatial distributions of CO/argon gas and carbon element. The water model experiment and the industrial experiment are carried out to verify the mathematical models.

Findings

A two-way coupling model (T-WCM) based on algebraic slip model is developed to investigate the coupling phenomena. The related results show that T-WCM is more rigorous and accurate than one-way coupling model in predicting carbon content of molten steel. The amount of CO gas, which can enhance turbulent flow and mass transfer, is about three times the argon gas blown into SSRH.

Originality/value

CO gas is the key factor in investigating the transport phenomena. This study fully reveals the truth about the unsteady gas-liquid flow in SSRH. It is necessary to adopt T-WCM based on algebraic slip model to describe the CO-Ar-molten steel flow phenomenon.
