Abstract

With significant changes in the aviation industry, various airport–airline arrangements have been formed to achieve alternative objectives. However, no consensus has been reached on such arrangements’ economic effects and the associated optimal public policy. This chapter aims to provide an interpretive review of the common types of airport–airline arrangements, the different modeling approaches used and key conclusions reached by recent studies. Our review suggests that airport–airline arrangements can take diverse forms and have been widely used in the industry. They may allow the airport and its airlines to internalize demand externality, increase traffic volume, reduce airport investment risks and costs, promote capacity investment, enhance service quality, or simply are a response to the competition from other airport–airline chains. On the other hand, such vertical arrangements, especially for those exclusively between airports and selected airlines, could lead to collusive outcomes at the expenses of non-participating organizations. The effects of such arrangements are also significantly influenced by the contract type, market structure and bargaining power between the airport and airline sectors. While case by case investigations are often needed for important economic decisions, we recommend policy-makers to promote competition in the airline and airport segments whenever possible, and demand more transparency or regulatory reporting of such arrangements. Policy debates and economic studies should be carried out first, before intrusive regulations are introduced.

Abstract

This chapter reviews the effects of air transport liberalization, and investigates the roles played by airport-airline vertical arrangements in liberalizing markets. Our investigation concludes that liberalization has led to substantial economic and traffic growth. Such positive outcomes are mainly due to increased competition and efficiency gains in the airline industry, and positive externalities to the overall economy. Liberalization allows airlines to optimize their networks, and thus may introduce substantial demand and financial uncertainty to airports. Vertical arrangements between airlines and airports may offer a wide range of benefits to the parties involved, yet such arrangements could also lead to airline entry barriers which reduce the effects of liberalization. Three approaches have been developed to model the effects of liberalization in complex market conditions, which include the analytical, econometric and computational network methods. These approaches should be selectively utilized in policy studies on liberalization.

Abstract

The relationship between airline and airport is complex, fascinating, and wide open for new research endeavors. In Volume 6 of the series, we conducted the analyses of risk-sharing contract between airline and airport from numerical risk balance assessment and incomplete contract theory perspectives based on an interesting real example of risk-sharing contracts, the Noto Airport Load Factor Guarantee Mechanism (LFGM) contract in Japan.

In this chapter, we further advance the analyses of risk-sharing contracts, based on the real example of Noto LFGM contract, from the perspectives of game theory and principal-agent theory. The risk-sharing arrangements, such as LFGM contract, are relevant to the rapidly changing business environment in Asia’s aviation industries.

We conduct a two-stage game analysis. The first phase is the contract negotiation phase and the second phase is the effort-making phase after signing the contract. We show that the two parties can attain a Pareto optimal utility level by bargaining a simple linear risk-sharing contract in the contract negotiation phase based on the equilibrium effort levels in the effort-making phase.

Abstract

Purpose

The current study examines the relation of guanxi human resource management (HRM) practices with subjective evaluations of creative performance by direct supervisors, as well as conceptualizes the employee ambidextrous behavior as a mediator, and social comparison orientation and leader–member exchange (LMX) as moderators for understanding the relation.

Design/methodology/approach

Survey data were collected from 211 employee–supervisor dyads in China. Hierarchical regression analyses, Preacher and Hayes’ (2008) indirect effects PROCESS macro, and Preacher et al.'s (2007) moderated mediation analysis approach were conducted to test the hypothesized relationships.

Findings

Guanxi HRM practices were negatively associated with employee creative performance, mediated by the employee ambidextrous behavior. The authors also found that social comparison orientation showed a strong moderating effect, such that it amplified the indirect relationship between guanxi HRM practices and employee creative performance via ambidextrous behavior. In contrast, LMX showed a weak moderating effect, such that it attenuated this indirect relationship.

Originality/value

This study provides evidence that the extent to which employee ambidextrous behavior mediates the relationship between guanxi HRM practices and creative performance depends on LMX and social comparison orientation. It represents a promising new direction for the guanxi HRM practices and creative performance literatures.

Abstract

Purpose

The current study examines the effects of leader humor on the creativity of employees by focusing on the mediating role of relational energy and the moderating role of traditionality.

Design/methodology/approach

This study used three-wave data from 302 employee–supervisor dyads and tested the hypotheses using hierarchical regression and bootstrapping.

Findings

The results indicated that leader humor was positively associated with employee creativity, relational energy mediated this influence. Besides, traditionality not only moderated the relationship between leader humor and relational energy but also attenuated the indirect relationship between leader humor and employee creativity through relational energy.

Practical implications

Leadership training programs can be used to assist leaders in improving their humorous skills. In addition, supervisors should implement humorous behaviors according to the different levels of traditionality of employees.

Originality/value

Integrating conservation of resource theory, this study provides solid evidence that the extent to which relational energy mediates the relationship between leader humor and employee creativity depends on traditionality. It provides a new direction for leader humor.

Abstract

Purpose

The purpose of this paper is to examine the relationship between servant leadership and customer service behaviors by probing the mediating role of promotion focus and the moderating role of internal locus of control.

Design/methodology/approach

The authors hypothesized an indirect relationship between servant leadership and customer service behaviors through promotion focus. Also, the authors predicted that the positive relationship between servant leadership and promotion focus would be stronger for employees with low internal locus of control. The authors tested the theoretical model with data gathered across two phases over three months from 280 supervisor-subordinate dyads.

Findings

Results indicated that servant leadership was positively related to customer service behaviors via promotion focus. Results also showed that internal locus of control moderated the relationship between servant leadership and promotion focus, such that the relationship was stronger for employees low on internal locus of control. Furthermore, this moderated mediated model was supported. As predicted, the indirect effect was stronger when internal locus of control was low.

Research limitations/implications

This study extends the regulatory focus theory to the service context to investigate how and when servant leadership enhances customer service behaviors. The authors suggested promotion focus as a key mediating mechanism and revealed internal locus of control as a boundary condition for the effectiveness of servant leadership.

Originality/value

This study highlights the importance role of promotion focus in fostering customer service behaviors and provides novel theoretical insight regarding when servant leadership enhances customer service behaviors.

Abstract

Purpose

The purpose of this paper is to develop a finite volume approach for the simulation of three-dimensional two-phase (polymer melt and air) flow in plastic injection molding which is capable of robustly handling the mesh non-orthogonality and the discontinuities in fluid properties.

Design/methodology/approach

The presented numerical method is based on a cell-centered unstructured finite volume discretization with a volume-of-fluid technique for interface capturing. The over-relaxed approach is adopted to handle the non-orthogonality involved in the discretization of the face normal derivatives to enhance the robustness of the solutions on non-orthogonal meshes. A novel interpolation method for the face pressure is derived to address the numerical stability issues resulting from the density and viscosity discontinuities at the melt–air interface. Various test cases are conducted to evaluate the proposed method.

Findings

The presented method was shown to be satisfactorily accurate by comparing simulations with analytical and experimental results. Besides, the effectiveness of the proposed face pressure interpolation method was verified by numerical examples of a two-phase flow problem with various density and viscosity ratios. The proposed method was also successfully applied to the simulation of a practical filling case.

Originality/value

The proposed finite volume approach is more tolerant of non-orthogonal meshes and the discontinuities in fluid properties for two-phase flow simulation; therefore, it is valuable for engineers in engineering computations.

Abstract

Purpose

The purpose of this paper is to demonstrate a simple fiber sensor for simultaneous measurement of liquid refractive-index (RI) and temperature.

Design/methodology/approach

The sensor structure is formed by a long period fiber grating cascaded with a section of thin-core fiber. The long period fiber grating is fabricated on single mode fiber, followed by a section of 20-mm length thin-core fiber which is a modal interferometer.

Findings

Cladding mode interference between long period fiber grating and thin-core fiber modal interferometer is weak in the experimental investigation. Both of these two cladding mode type fiber devices are sensitive to surrounding RI and temperature. So the RI and temperature can be measured simultaneously by monitoring the spectral characteristics of the compound sensor. The sensitivity is calibrated and sensor matrix is provided in the experiment.

Originality/value

This proposed fiber sensor is simple, tough, cost-effective and suitable for discriminate the liquid RI and temperature with high sensitivity.

Abstract

Purpose

The purpose of this paper is to examine the causal correlation between the work stress of immigration officers (IOs) and the cross-level effect of social support.

Design/methodology/approach

A multilevel model was used to analyze the quantitative data obtained from 231 IOs in Taiwan, who served as the research objects.

Findings

From the results of this study, it was found that a positive significant relationship existed between role conflict and work stress, as well as between work stress and job burnout. Also, cross-level context and moderating effect for the relationship between social support and work stress, as well as between social support, work stress and job burnout were obtained.

Originality/value

This study only considered IOs in airports and ports. Therefore, it is necessary to determine if other topics of organizational behavior, such as the leadership of supervisors, organizational climate and work values of IOs, have a positive moderating effect. In this regard, it is recommended that a longitudinal study should be conducted in the future.

Abstract

Purpose

The phosphorus and zinc contained in zinc dialkyl dithiophosphate (ZDDP) caused severe environment pollution and catalyst poison. Thus, the phosphorus-free additive, such as borate esters, has become one of studying hot topics in the area of oil additive. However, the stability of hydrolysis greatly limited the use of borate esters. The purpose of this paper is to improve the stability of hydrolysis by synthesizing a new kind of N-containing heterocyclic borate ester (MTTDB) as a lubricant additive.

Design/methodology/approach

The tribological properties of novel borate ester (MTTDB) as an additive in the base oil were studied by a four-ball machine. The element composition and chemical state of the tribofilm were investigated by scanning electron microscopy, energy dispersive spectrometer and X-ray photoelectron spectroscopy.

Findings

The results showed that the base oil lubricated by MTTDB exhibited high hydrolytic stability, good anti-wear property and excellent extreme pressure performance. When 2.5 per cent MTTDB was added into the 100N base oil, the smallest wear scar diameter (0.46 mm) was obtained. Furthermore, the decomposed borate ester, organic sulfide adsorbed on the worn surface was detected, and S element reacted with the steel surface and generated FeSO4, both of which contributed to the formation of the tribofilm.

Originality/value

Based on N-containing heterocyclic compounds, for instance, thiadiazole derivatives, introducing nitrogen and sulfur elements into borate ester, a new kind of N-containing heterocyclic borate ester (MTTDB) exhibited excellent property in hydrolysis stability, friction-reducing, anti-wear and extreme pressure. This synthesized method would be helpful for the borate ester used as additive in engine oil, gear oil and other industrial lubricants.
