Abstract

Purpose

The purpose of this paper is to explore the dynamic influence of WTI crude oil returns on the stock returns of China’s traditional energy sectors, including oil and gas exploitation, coal mining and processing, petroleum processing and coking, electricity, heat production and supply and mining services.

Design/methodology/approach

Hong’s information spill-over test and the DP Granger causality test are applied to investigate the relationship between the two markets. Moreover, a rolling window is introduced into the above two tests to capture time-varying characteristics of the influence of WTI crude oil returns.

Findings

The empirical results indicate that, first, there exists significant bidirectional linear causality between WTI crude oil returns and China’s traditional energy sectoral stock returns, but the nonlinear causality appears weaker. Second, the influence of WTI crude oil returns on traditional energy sectoral stock returns has time-varying characteristics and industry heterogeneity both in the linear and nonlinear cases. Finally, the decline of WTI crude oil prices may strengthen its linear influence on the stock returns of traditional energy sectors, while the excessive rise of market values in traditional energy sectors may weaken the linear and nonlinear influence of WTI on them.

Originality/value

The general nexus between international crude oil market and China’s traditional energy stock market is explored both in the linear and nonlinear perspectives. In particular, the dynamic linear and nonlinear influence of WTI crude oil returns on China’s traditional energy sectoral stock returns and its industry heterogeneity are analysed in detail.

Abstract

Purpose

This study aims to clarify influencing factors of overcapacity of new energy enterprises in China and accurately predict whether these enterprises have overcapacity.

Design/methodology/approach

Based on relevant data including the experience and evidence from the capital market in China, the research establishes a generic univariate selection-comparative machine learning model to study relevant factors that affect overcapacity of new energy enterprises from five dimensions. These include the governmental intervention, market demand, corporate finance, corporate governance and corporate decision. Moreover, the bridging approach is used to strengthen findings from quantitative studies via the results from qualitative studies.

Findings

The authors' results show that the overcapacity of new energy enterprises in China is brought out by the combined effect of governmental intervention corporate governance and corporate decision. Governmental interventions increase the overcapacity risk of new energy enterprises mainly by distorting investment behaviors of enterprises. Corporate decision and corporate governance factors affect the overcapacity mainly by regulating the degree of overconfidence of the management team and the agency cost. Among the eight comparable integrated models, generic univariate selection-bagging exhibits the optimal comprehensive generalization performance and its area under the receiver operating characteristic curve Area under curve (AUC) accuracy precision and recall are 0.719, 0.960, 0.975 and 0.983, respectively.

Originality/value

The proposed integrated model analyzes causes and predicts presence of overcapacity of new energy enterprises to help governments to formulate appropriate strategies to deal with overcapacity and new energy enterprises to optimize resource allocation. Ten main features which affect the overcapacity of new energy enterprises in China are identified through generic univariate selection model. Through the bridging approach, the impact of the main features on the overcapacity of new energy enterprises and the mechanism of the influence are analyzed.

Abstract

Purpose

Due to the cross-network effect, two-sided users communicate with each other, producing a coupling network. To study the spread of platform self-operation in two-sided users' marketing and purchasing tactics, this paper considers the differences in reputation acquired by platform-owned and third-party operating channels.

Design/methodology/approach

This study proposes a two-layer network with cross-network links: one layer represents the social network of consumers, while the other layer represents the competitive network of buyers. A closed system of differential equations, based on the binary dynamics of the stochastic network, is developed to study the trend and stability points of the platform self-operation dissemination. Then the overall benefits of platform are analyzed to unify the platform diffusion and pricing strategies.

Findings

The degree of difference in social influence and cross-network effects affect diffusion synergistically. Cross-network effects hinder diffusion when there is a significant difference of social influence between consumers and sellers but promote diffusion when there is little difference of social influence between consumers and sellers. Additionally, the network weights and reputation gap exhibit a nonlinear correlation with diffusion. For pricing strategy of the platform, it can achieve maximum profit when the pricing of self-operated goods and third-party-operated goods is equal.

Originality/value

This study considers the complex network architecture created by bilateral markets and the dynamic influence of group interactions on product. Additionally, this study takes reputation into account when considering the price and dissemination tactics of various operating channels, offering guidelines for platforms to control merchants and mediate disputes between various operating channels.

Abstract

Aims to set systems thinking into the context of manufacturing systems management (MSM), which is defined as a functional domain that involves the necessary activities such as design, implementation, operations and monitoring, needed to regulate and optimise a manufacturing system as it progresses through its life cycle. Based on a number of key principles of systems theory, results from an extensive analysis of the relevant methodologies and techniques, and data gathered through industrial practice, a conceptual MSM framework is proposed. This framework specifies the key functional areas of MSM, outlines the contents and relationships within them, and then logically integrates these into a closed loop to provide the basis for the development of a set of consistent parameters and procedures. Its aim is to help achieve understanding of the problem domain, and to provide guidance for the development of effective mechanisms and tools for future MSM activities. A number of cases to illustrate its industrial application are also presented.

Abstract

Lai, Li, Conover, and Wu (2010) propose a four-factor financial distress model to explain stock returns in the U.S. and Japanese markets. We examine this model in the stock markets of Australia, and six Asian markets (Hong Kong, Indonesia, Korea, Malaysia, Singapore, and Thailand). We find broad empirical support for the four-factor financial distress risk asset-pricing model in those markets. The four-factor financial distress asset pricing model improves explanatory power beyond the Fama–French (1993) three-factor asset pricing model in six of the seven Asian-Pacific markets (12 of 14 portfolio groupings), while the Carhart (1997) momentum-based asset pricing model only improves explanatory power beyond the Fama–French model in three of the seven markets (4 of 14 portfolio groupings).

Abstract

Purpose

In the recent past, academic researchers have noted the quantity of food wasted in food service establishments in educational institutions. However, more granular inputs are required to counter the challenge posed. The purpose of this study is to undertake a review of the prior literature in the area to provide a platform for future research.

Design/methodology/approach

Towards this end, the authors used a robust search protocol to identify 88 congruent studies to review and critically synthesize. The research profiling of the selected studies revealed limited studies conducted on food service establishments in universities. The research is also less dispersed geographically, remaining largely focused on the USA. Thereafter, the authors performed content analysis to identify seven themes around which the findings of prior studies were organized.

Findings

The key themes of the reviewed studies are the drivers of food waste, quantitative assessment of food waste, assessment of the behavioural aspects of food waste, operational strategies for reducing food waste, interventions for inducing behavioural changes to mitigate food waste, food diversion and food waste disposal processes and barriers to the implementation of food waste reduction strategies.

Research limitations/implications

This study has key theoretical and practical implications. From the perspective of research, the study revealed various gaps in the extant findings and suggested potential areas that can be examined by academic researchers from the perspective of the hospitality sector. From the perspective of practice, the study recommended actionable strategies to help managers mitigate food waste.

Originality/value

The authors have made a novel contribution to the research on food waste reduction by identifying theme-based research gaps, suggesting potential research questions and proposing a framework based on the open-systems approach to set the future research agenda.

Abstract

Purpose

The purpose of this paper is to introduce a novel and concise technique of fabricating HA/β‐TCP composite ceramic scaffolds for bone tissue engineering via extrusion deposition method.

Design/methodology/approach

A new rapid prototyping (RP) machine called motor assisted micro‐syringe (MAM) system is used in the authors' research. It is implemented to control the morphology, pore size and porosity of scaffolds precisely and to optimize their mechanical properties in this study.

Findings

In the fabrication process, HA/β‐TCP ceramic composite slurry with prominent uniformity, stability and liquidity is prepared by deliberating the influential factors such as its ingredient, pH and viscosity. After optimizing the system parameters, scaffolds with homogeneous and interconnected pores in sizes ranging from 50 to 580 μm were obtained, and the whole process had excellent stability and repeatability. The average compressive strength of scaffolds with a porosity of around 50% reaches 50.33 MPa after sintered in microwave furnace at 1,200°C for 30 min.

Research limitations/implications

Degradation rates and biological properties concluding experiments in vitro and vivo should be further investigated.

Practical implications

The paper describes a brief method with excellent stability and repeatability which is practical for manufacturing composite ceramic scaffolds with desirable structures and strength.

Originality/value

The mentioned method can be used in tissue engineering, not only proper for ceramics scaffolds but many medical application fields such as implants.

Abstract

The role of dark side personality characteristics in the workplace has received increasing attention in the organizational sciences and from leadership researchers in particular. We provide a review of this area, mapping out the key frameworks for assessing the dark side. We pay particular attention to the roles that the dark side plays in leadership processes and career dynamics, with special attention given to destructive leadership. Further, we examine the role that stress plays in the emergence of leaders and how the dark side plays into that process. We additionally provide discussion of the possible roles that leaders can play in producing stress experiences for their followers. We finally illustrate a dynamic model of the interplay of dark leadership, social relationships, and stress in managerial derailment. Throughout, we emphasize a functionalist account of these personality characteristics, placing particular focus on the motives and emotional capabilities of the individuals under discussion.

Abstract

Purpose

Configuration systems are used as a means for efficient design of customer tailored product service systems (PSS). In PSS configuration, mapping customer needs with optimal configuration of PSS components have become much more challenging, because more knowledge with personalization aspects has to be considered. However, the extant techniques are hard to be applied to acquire personalized configuration rules. The purpose of this paper is to extract the configuration rule knowledge in symbolism formulation from historical data.

Design/methodology/approach

Customer characteristics (CCs) are defined and introduced into the construction of configuration rules. Personalized PSS configuration rules (PCRs) are thereby proposed to collect and represent more knowledge. An approach combining Local Cluster Neural Network and Rulex algorithm is proposed to extract rule knowledge from historical data.

Findings

The personalized configuration rules with CCs are able to alleviate the burden of customers in expressing functional requirements. Furthermore, in the long-term relationship with a customer in PSS realization, PSS offerings can be reconfigured according to the changing CCs with the guide of PCRs.

Originality/value

The contribution of this paper lies in introducing the attribute of CCs into the antecedents of PCRs and proposing the neural networks-based approach to extracting the rule knowledge from historical data.
