Abstract

Purpose

This study examined a curvilinear and moderated relationship between transformational leadership and employee creative performance in a real-world setting by drawing from the too-much-of-a-good-thing effect and the substitutes for leadership perspectives.

Design/methodology/approach

We used multisource data collected from 232 employees and their immediate supervisors to test all hypotheses.

Findings

We found empirical support for an inverted U-shaped relationship between transformational leadership and employee creative performance. Moreover, job factor (i.e. job formalization) and individual differences (i.e. power distance) moderated the curvilinear relationship, such that the curvilinear relationship was more pronounced with lower job formalization or higher power distance of employees.

Originality/value

Our findings shed light on the inconsistent reports of transformational leadership's effects on employee creativity in previous studies. We extended substitutes for leadership perspective by providing a more systematic view for future research on how leadership and its substitutes jointly influence employee outcomes.

Abstract

This chapter reviews three main issues in the interactions between air transport and high-speed rail (HSR) in China, namely the interaction between low-cost carriers (LCCs) and HSR, HSR speed effect on airlines, and airline–HSR integration. Studies on these three aspects of airline–HSR interactions have yet been well reviewed, and our chapter aims to fill in this gap. In this chapter, we comprehensively survey literature on the topics, especially studies on Chinese markets that have recently witnessed major HSR developments (and have planned further large-scale HSR expansion in the coming years). Our review shows that, first, compared to full-service carriers, LCCs face fiercer competition from HSR. However, the expansion of HSR network in China can be better coordinated with LCC development. Second, HSR speed exerts two countervailing effects on airline demand and price (the “travel-time” effect and “safety” effect, respectively). Specifically, an HSR speed reduction can have a positive effect on airlines due to longer HSR travel time, but a negative effect on airlines due to improved perception on HSR safety. Third, airline–HSR integration can be implemented through cooperation between airlines and HSR operators and through co-location of airports and HSR stations and can have important implications for intermodal transport and social welfare.

Abstract

Airport economics literature has recently included the supply of concession services among the factors that might affect airport pricing. In particular, there is only little empirical analysis on whether: (i) the supply of airport concession services can stimulate the demand for travel (two-side complementarity) and (ii) the demand for airport concession services is independent of traveling activities (welfare neutrality). In this chapter, we survey papers that have addressed two-side complementarity and welfare neutrality in airport concessions. Our goal is to discuss the different assumptions that have shaped the models and to collect evidences, facts and empirical findings that may support analytical hypotheses. We argue that the notions of two-side complementarity and welfare neutrality might be interrelated – especially when airports invest in concessions in the area accessible to non-passengers. Welfare gains should be assessed on a case by case basis, depending on the type of airport in terms of ownership, size (and the relative mass of connecting passengers compared to origin–destination passengers), and the source of concession revenues. Our arguments might be particularly relevant to policy makers who need to understand (i) whether the supply of concessions reduces or increases the benefits of airport (aviation) price regulation and (ii) whether the effective control of market power may require the regulation of the prices of both the businesses.

Abstract

Purpose

The purpose of this paper is to examine how the magnitude of strategic change may be influenced by Chief executive officer (CEO) underpayment relative to comparison CEOs. Based on equity theory, the authors propose that compensation inequity motivates underpaid CEOs to restore equity, which can take the form of making a greater magnitude of strategic change. In addition, this study proposes three important moderators of the relationship between CEO underpayment and strategic change.

Design/methodology/approach

Results from a sample covered in the Standard & Poor’s (S&P) ExecuComp database for the years 1996-2014 provide support for these theoretical predictions.

Findings

CEO underpayment has a positive effect on the magnitude of strategic change. Top management team compensation gap and firm slack are proposed to weaken the impact of CEO underpayment on strategic change, while environmental complexity is predicted to strengthen the relationship between CEO underpayment and strategic change.

Originality/value

This study contributes to strategic change literature by linking research on CEO relative compensation to strategic change studies. This study contributes to equity theory and CEO relative compensation literature by extending its implications to firms’ decisions on strategic change. Moreover, it also contributes to equity theory by revealing the boundary conditions that mitigate or aggravate the impacts of CEO underpayment on firms’ strategic decisions.

Abstract

Purpose

The purpose of this paper is to examine how analyst recommendation change is associated with a firm’s magnitude of strategic change.

Design/methodology/approach

This study argues that unfavorable analyst recommendation change serves as a powerful external assessment that current strategies are inappropriate and that changes are needed. This study also incorporates the moderating roles of CEO power and board’s informal hierarchy in the relationship between analyst recommendation change and firm’s magnitude of strategic change. Results from a sample of 824 observations generally support our predictions.

Findings

The findings of this study show that the greater the analysts downgrade for the company’s stock, the larger the magnitude of strategic change will be made. This study also considers the moderating roles of CEO power and the clarity of board’s informal hierarchy. In particular, the higher the CEO power, the weaker the relationship between analyst recommendation change and the magnitude of strategic change will be. The higher the clarity of board’s informal hierarchy, the more positive the relationship between analyst recommendation change and the magnitude of strategic change will be.

Originality/value

It extends research on the external predictors of strategic change by incorporating the role of unfavorable analyst recommendation change. In addition, it contributes to institutional theory by showing how external legitimacy pressure and internal corporate governance tool complement each other.

Abstract

Purpose

This study aims to develop a low-cost additive-subtractive hybrid machine equipped with reverse scanning to fabricate high-precision dental surgical guides. The major focus of developing the hybrid additive manufacturing technology is to achieve clinical precision of dental tools at an affordable price.

Design/methodology/approach

The designed machine consists of a self-developed vat-photopolymerization-based 3D printer that can fabricate dental surgical guides. The 3D printer is integrated with a self-developed 3D scanner that will analyze the fabricated part and evaluate the dimensional discrepancies. Based on the data provided by the scanner, the integrated secondary milling process will successfully machine the part to meet the clinical precision and standard.

Findings

The efficacy of the newly developed hybrid machine is demonstrated with the fabrication of complex part, lower and upper dental surgical guides with the mean dimensional deviations of 198.1, 136.6 and 117.9 µm, respectively. The integration of the secondary scanning and machining system successfully enhanced the mean dimensional deviation of upper and lower guides by 11.88% and 28.75%, respectively. Furthermore, this study also benchmarked the dimensional accuracies achieved by this low-cost technology with the high-end commercial 3D printers. The overall cost of the machine is evaluated to be $2,399.

Originality/value

This paper proposes a novel hybrid additive manufacturing process with integrated reverse scanning and machining modules to fabricate high-precision dental guides. The developed machine is a low-cost alternative to the existing high-end commercial counterparts. The developed machine has the potential to make endodontic treatments more affordable.

Abstract

Purpose

This study aims to build on equity theory to assess the effect of chief executive officer (CEO) underpayment on the accumulation of firm-specific knowledge, accounting for the moderating effects of the CEO compensation gap and the clarity of the board’s informal hierarchy.

Design/methodology/approach

This study starts with all firms listed in the Execucomp database for the period 1992 to 2006. Then, all data sources are merged and entries with missing information are excluded. The final data set used for model estimations includes 1,152 firm-year observations. The command xtreg in Stata 12 with the fixed-effect option (fe) is used to estimate the relationship between CEO underpayment and firm-specific knowledge.

Findings

This study proposed and examined the role of CEO underpayment in discouraging CEO willingness to invest firm-specific human capital and, accordingly, to adopt a strategy of accumulating lower levels of firm-specific knowledge assets. The empirical analyses strongly support this argument. Moreover, CEO compensation gaps and the informal hierarchy of boards negatively moderated this relationship. That is, CEO underpayment had a weaker negative effect on firm-specific knowledge when the CEO compensation gap and the clarity of the board’s informal hierarchy were high.

Originality/value

Prior studies from the knowledge-based perspective have focused on the importance of firm-specific knowledge in enabling a firm to achieve superior financial performance. However, relatively little attention has been paid to CEOs’ willingness to accumulate firm-specific knowledge. The present study contributes to the knowledge-based view of the firm. This study integrates equity theory with the knowledge-based view of the firm by highlighting how unfair compensation of CEOs may discourage them to fully realize a firm’s potential to generate specific knowledge. By incorporating the fairness issue of CEO compensation into the knowledge-based view, this study contributes to a deeper understanding of the origins of firm-specific knowledge.

Abstract

Purpose

Smart community construction (SCC) and efficiency require resident participation. This paper aims to explore the determinants of residents’ participation intention (RPI) in the SCC.

Design/methodology/approach

Based on the theory of planned behavior (TPB), this study proposed an extended conceptual model to deeply analyze the RPI in the SCC. The relationship between all constructs was verified by processing and analyzing online survey data using confirmatory factor analysis (CFA), structural equation model (SEM), and bootstrapping method.

Findings

Participation attitude, perceived behavioral control, subjective norm, and perceived usefulness significantly and positively affected the RPI. Furthermore, intermediary effects in the extended conceptual model had been confirmed.

Originality/value

To fill the critical gap in the research on the determinants of the RPI in the SCC context, this study developed a novel conceptual model by extending the TPB to analyze the effects of self-driven and externally-driven factors on the RPI from the perspectives of residents’ psychology and external environment. The findings not only clarify the complex process of forming the RPI in the SCC but also provide a theoretical foundation for studying the RPI in similar community construction projects. Additionally, several strategies have been proposed to encourage residents’ participation in the SCC and promote the development of smart communities, such as clarifying residents’ participation obligations, improving the convenience services of smart communities, and diversifying residents’ participation approaches.

Abstract

Purpose

Airport capacity constraints lead to operational congestion and delays, which have become major threats to the aviation industry. They impose large costs on airlines and their passengers. Uncertainty in demand or unexpected events can cause a mismatch between capacity and demand, resulting in either capacity oversupply, with a decrease in efficiency, or airport congestion over an extended period. Moreover, airport capacity is rather difficult to define due to its multifaceted and dynamic nature, and it depends both on the available infrastructure and on operating procedures. Additionally, traditional capacity management methods do not consider relevant behavioral economic challenges to conventional analysis, particularly failure of the expected utility hypotheses and dependence of valuations on reference points. This study aims to develop a preliminary framework to include economic concepts when evaluating expansions of airport capacity.

Design/methodology/approach

This paper reviews major opportunities in airport demand and capacity management from an economic perspective while appraising the challenges involved in airport capacity expansion processes that have not been fully completely in past studies. Although welfare economics provides the conceptual foundations for demand/capacity analyses, the authors integrate the findings regarding capacity definition, uncertainty management and behavioral economics into standard economics to guide the measurement of the airport capacity expansion problem.

Findings

The authors obtain several insights regarding airport capacity and demand management. First, airport capacity is a complex metric when evaluating airport expansion, and it depends both on the available infrastructure and on operating procedures. Furthermore, airport throughput is highly conditioned by factors that shape capacity and delay and shows significant variability when these factors are modified. Second, a marginal change in capacity at congested airports may have a great impact on demand distribution, airline competition, aircraft types, fares, operating revenues, route map and other characteristics of a given airport. Behavior after capacity expansion is highly reliant on the slot allocation models. Additionally, overall social welfare is usually affected after changes in infrastructure in terms of increased connectivity, economic benefits and negative externalities, including noise and local pollution. Third, on-time performance is clearly nonlinear, and thus sensitive to variations in demand and capacity. Finally, airport capacity and demand management involve a trade-off between mitigating congestion and maximizing capacity utilization, so decision-making tools are required to support and enhance policy and managerial choices. Three main challenges arise when developing new methods for evaluating airport expansions: the definition of capacity, the management of uncertainty in demand and the need to consider economic concepts.

Originality/value

This paper explores and produces an in-depth understanding of the problem of airport capacity and demand balance. The authors propose a preliminary framework that considers the challenges that have been previously identified and that, particularly, provides an economic perspective for airport capacity expansion processes. This framework is completed with a theoretical model to help policymakers and airport operators when faced with a capacity development decision.

Abstract

Purpose

This study aims to evaluate the thermal performance of sodium alginate (SA) aerogel attached to nano SiO2 and its radiative cooling effect on firefighting clothing without environmental pollution.

Design/methodology/approach

SA/SiO2 aerogel with refractory heat insulation and enhanced radiative cooling performance was fabricated by freeze-drying method, which can be used in firefighting clothing. The microstructure, chemical composition, thermal stability, and thermal emissivity were analyzed using Fourier transform infrared spectroscopy, scanning electron microscopy, thermogravimetric analyzer and infrared emissivity measurement instrument. The radiative cooling effect of aerogel was studied using thermal infrared imager and thermocouple.

Findings

When the addition of SiO2 is 25% of SA, the prepared aerogel has excellent heat insulation and a high radiative cooling effect. Under a clear sky, the temperature of SA/SiO2 aerogel is 9.4°C lower than that of pure SA aerogel and 22.1°C lower than that of the simulated environment. In addition, aerogel has more exceptional heat insulation effect than other common fabrics in the heat insulation performance test.

Research limitations/implications

SA/SiO2 aerogel has passive radiative cooling function, which can efficaciously economize global energy, and it is paramount to environment-friendly cooling.

Practical implications

This method could pave the way for high-performance cooling materials designed for firefighting clothing to keep maintain the wearing comfort of firefighters.

Originality/value

SA/SiO2 aerogel used in firefighting clothing can release heat to the low-temperature outer space in the form of thermal radiation to achieve its own cooling purpose, without additional energy supply.
