Abstract

Purpose

Considering two types of subsidies for producers (supplier and manufacturer) and one for consumers based on product greenness and sales quantity, this study aims to formulate optimal supply chain green innovation and subsidy strategies, and to achieve this goal with the support of information systems.

Design/methodology/approach

This study introduces a composite green-product supply chain where suppliers focus on green innovation for component greenness and manufacturers focus on green innovation for manufacturing process greenness. Game theory modeling is applied to investigate the differences of product greenness, supply chain members’ profit and social welfare under different government subsidy strategies.

Findings

Increasing the unit greenness subsidy coefficient can boost product greenness and supply chain members’ profits, but does not always raise social welfare. When the government exclusively offers subsidies to producers, subsidies should be allocated to suppliers when there is a significant disparity in supply chain green innovation costs. Conversely, it is more beneficial to subsidize manufacturers. Consumer subsidies have the potential to enhance both environmental and economic performance in the supply chain compared with producer-exclusive subsidies, but may not always maximize social welfare when supply chain members have low unit costs associated with green innovation.

Originality/value

This study examines the optimal decisions for green supply chain innovation and government subsidy strategies. Supply chain members and the government can use the information system to collect and evaluate the cost of upstream and downstream green innovation, and then develop reasonable collaborative green innovation and subsidy strategies.

Abstract

This study surveys a broad spectrum of US manufacturer and service firms to examine the effect of tacit knowledge transfer on firm innovation capability. The authors present a set of hypotheses concerning the relationships between inter‐firm relationship strength and tacitness of knowledge transfer, extent of tacit knowledge transfer and innovation capability, and innovation capability and innovation performance based on the theory of knowledge. Moderating roles of firm collaborative experience and firm size on the relationship between inter‐firm relationship strength and the extent of tacit knowledge transfer are considered. Empirical results generally support the predictions from the theory and managerial implications are included.

Abstract

This study compares the motivation, perceived crowding and satisfaction differences among local climbers in three Asian countries. The study population consists of mountain climbers from Taiwan's Yushan, Japan's Mount Fuji and Malaysia's Mount Kinabalu. The study involves 3,112 respondents from Mount Fuji, 192 from Mount Kinabalu and 391 from Yushan. The results from the Multivariate Analysis of Variance (MANOVA) show significant differences among climbers on the three mountains concerning climbers' motivation, perceived crowding and satisfaction. Social factors are the most significant motivators, with climbers on Mount Kinabalu, representing the most salient motivation for mountain tourism. For perceived crowding, climbers on Mount Fuji perceive congestion on the trails, mountaintops, restrooms and mountain huts and regard those services as unacceptable. Concerning satisfaction, services provided by mountain huts are the most significant, with the highest satisfaction recorded at Yushan's mountain huts. The study findings may be used as a reference for relevant tourism stakeholders and guide future research directions.

Abstract

Purpose

The purpose of this study is to systematically investigate the novel phenomenon of rail corrugation on small radius curves with rail joints in mountainous city metros, characterized by the coexistence of short and long wavelengths (30–40 mm and 150–200 mm) on the low rail.

Design/methodology/approach

The finite element model of the wheel-rail system in the section with rail joint is constructed based on field surveys. The friction-coupled vibration characteristics of the wheel-rail system are studied from the perspective of friction self-excited vibration of the wheel-rail system and feedback vibration of the rail irregularity.

Findings

The rail corrugation with short wavelength is primarily induced by the friction self-excited vibration of wheel-rail system. In contrast, the rail corrugation with long wavelength is predominantly caused by the feedback vibration of rail joint irregularity. Additionally, the feedback vibration of corrugated irregularity accelerates the progression of corrugation depth without triggering the emergence of rail corrugation with new wavelength.

Originality/value

The research advances the understanding of the vibration inducement behind rail corrugation in mountainous city metros.

Abstract

Purpose

This study aims to understand how organizations in the service industry can encourage the use of enterprise social networks (ESNs) for knowledge sharing, focusing on the concepts of intra-organizational trust and governance.

Design/methodology/approach

The authors gathered data through an online survey of 104 participants from the financial services industry. Data were analyzed using structural equation modelling to test the proposed model and evaluate the constructs’ reliability and validity.

Findings

The findings of the survey data indicate that intra-organizational trust and governance are related to the use of ESN for knowledge sharing to enhance service innovation. Further, the findings suggest that, although trust directly affects service innovation, using ESN for knowledge sharing partially mediates the relationship between trust and service innovation. The findings also reveal that governance significantly moderates the relationship between ESN for knowledge sharing and innovation.

Originality/value

This paper provides insights into the relationship between trust, knowledge sharing and innovation. The novelty of this study demonstrates that governance strengthens the relationship between ESN for knowledge sharing and innovation. Further, the study suggests that firms using or intending to use ESNs could keep track of the evolving nature of ESNs, develop an open culture and create a trusted environment in their organizations.

Abstract

Purpose

This study aims to examine the effect of the Internet on irrigation system adoption. The authors implement the most extensive household survey of irrigation arrangements ever conducted in rural China and also exploit a public program to improve the quality of distance education in rural middle schools, which has led to plausibly exogenous variation in Internet access across rural districts.

Design/methodology/approach

The authors present a conceptual framework highlighting the transmission mechanisms whereby Internet access may affect irrigation system selection and identify direct effects through agricultural production and an indirect effect through non-agricultural production. To examine the effect of the Internet on irrigation system adoption, we implement the most extensive household survey of irrigation arrangements ever conducted in rural China. We also exploit a public program to improve the quality of distance education in rural middle schools, which has led to plausibly exogenous variation in Internet access across rural districts.

Findings

The authors find evidence to suggest that Internet access can effectively reduce information frictions and searching costs in the non-agricultural labor market, thus increasing rural households' participation in non-farm work. To save more hours from agricultural production, rural households select more labor-saving irrigation systems.

Originality/value

This study’s findings have important implications for the ongoing policy debate over government investment in Internet infrastructure to improve agricultural development in rural and isolated areas.

Abstract

Purpose

Regeneratively cooled thrust chamber is a key component of reusable liquid rocket engines. Subjected to cyclic thermal-mechanical loadings, its failure can seriously affect the service life of engines. QCr0.8 copper alloy is widely used in thrust chamber walls due to its excellent thermal conductivity, and its mechanical and fatigue properties are essential for the evaluation of thrust chamber life. This paper contributes to the understanding of the damage mechanism and material selection of regeneratively cooled thrust chambers for reusable liquid rocket engines.

Design/methodology/approach

In this paper, tensile and low-cycle fatigue (LCF) tests were conducted for QCr0.8 alloy, and a Chaboche combined hardening model was established to describe the elastic-plastic behavior of QCr0.8 at different temperatures and strain levels. In addition, an LCF life prediction model was established based on the Manson–Coffin formula. The reliability and accuracy of models were then verified by simulations in ABAQUS. Finally, the service life was evaluated for a regenerative cooling thrust chamber, under the condition of cyclic startup and shutdown.

Findings

In this paper, a Chaboche combined hardening model was established to describe the elastoplastic behavior of QCr0.8 alloy at different temperatures and strain levels through LCF experiments. The parameters of the fitted Chaboche model were simulated in ABAQUS, and the simulation results were compared with the experimental results. The results show that the model has high reliability and accuracy in characterizing the viscoplastic behavior of QCr0.8 alloy.

Originality/value

(1)The parameters of a Chaboche combined hardening constitutive model and LCF life equation were optimized by tensile and strain-controlled fatigue tests of QCr0.8 copper alloy. (2) Based on the Manson–Coffin formula, the reliability and accuracy of constitutive model were then verified by simulations in ABAQUS. (3)Thermal-mechanical analysis was carried out for regeneratively cooled thrust chamber wall of a reusable liquid rocket engine, and the service life considering LCF, creep and ratcheting damage was analyzed.

Abstract

Purpose

The replenishment of construction materials heavily relies on the functioning of heavy machinery, which often leads to confusion and negotiations among construction work groups regarding the allocation rights of these materials. When multiple groups require the same construction materials, they often struggle to determine whether the delivered materials are intended for their own use or if they have encroached upon supplies designated for others. Such uncertainties and negotiations frequently result in delays in construction progress and have the potential to escalate into conflicts. To minimize misunderstandings among work groups and mitigate the risk of severe safety consequences, it is crucial to understand the decision-making processes involved in the interaction between work groups.

Design/methodology/approach

This paper adopts a game theory approach to examine the interactions among work groups from a safety perspective. Quantum response equilibrium (QRE), as a specialized form of game with incomplete information, is assumed to govern the behavior of work groups in this study. By conducting a questionnaire survey, interactive scenarios were simulated. A resource overlap scenario for high-altitude construction is established, with the key factors being the importance of construction materials, the time required to supplement materials, whether managers are present and the climate within the groups. The model parameters were estimated using the expectation–maximization algorithm. Additionally, individual traits and safety awareness are surveyed in the questionnaire, further explaining the results of the game.

Findings

The findings indicate that the likelihood of conflicts between work groups under resource overlap can be quantified. The radical behavior of construction work groups exhibits a positive correlation with the importance of construction materials and the time required for material replenishment. Furthermore, the presence of a safety climate and the oversight of management personnel play a significant role in maintaining the composure of construction work groups. The expanded results of the questionnaire demonstrate that there is considerable room for improvement in workers' safety awareness, and management approaches can be further enhanced to prevent unsafe behaviors from occurring.

Originality/value

A novel game theory model was developed to evaluate the behavior of construction groups in situations of resource overlap. This model offers practical suggestions to improve safety performance and efficiency in construction projects.
