This paper offers limited discussion of the wider area of scientific discoveries.

The findings may impact future interdisciplinary research, health/well-being practices and public policy.

There is no known to us publication interpreting the parallels between the theory of the Physical Vacuum and the concept of Qi.

The purpose of this paper is to examine the impact of ethical leadership on employee task performance, specifically the mechanisms through which ethical leadership impacts employee task performance and the moderating role of employee proactive personality. Social identity, social learning, and self-concordance theory were used to explain the way ethical leadership affects employee task performance, and provided another way to understand this relationship.

The authors collected survey-based dyadic data from middle management team members and subordinates in Chinese companies. Multiple regression analysis was used to test the research hypotheses.

The empirical findings indicate that ethical leadership positively influences employee task performance. Organizational identification (OID) mediates the relationship between ethical leadership and employee task performance. Furthermore, the relationship between ethical leadership and employee task performance via OID is moderated by employee proactive personality.

Employee task performance is critical for a firm’s competitive advantage. This paper adds to knowledge about the relationship between ethical leadership and employee task performance and contributes to effective management.

Farmers' adaptation strategies in agricultural production are required to minimise the negative impact of climate change on a nation's food production in developing countries. Based on the panel data of the provincial level in China from 2000 to 2017, this study aims to analyse the changing climate over recent years and farmers' adaptation strategy in terms of cropping in agricultural production.

This study uses Simpson's diversity index (SDI) to measure the degree of crop diversity planted by farmers and evaluate the influence of climate change on farmers' cropping strategy using the fixed-effect model. Further, the authors estimate the impact of farmers' cropping strategy on their economic performances in two aspects including yields and technical efficiency of crops.

The empirical results show that the overall climate appears a warming trend. Different from farmers in some other countries, Chinese farmers tend to adopt a more specialised cropping strategy which can significantly improve the technical efficiency and yields of crops in agriculture. In addition, as a moderating role, the specialised cropping can help farmers to alleviate the negative impact of climate change on technical efficiency of their crops.

First, previous studies showed that the changing climate influenced farmers' adaptation strategies, while most studies focussed on multiple adaptation strategies from the farm-level perspective rather than cropping strategy from the nation-level perspective. Second, the present study investigates how the cropping strategy affects the economic performance (in terms of the technical efficiency and crop yields) of agricultural production. Third, the stochastic frontier analysis method is used to estimate the technical efficiency. Fourth, this study explores the moderating effect between farmers' cropping strategy and technical efficiency by introducing an interaction item of SDI and accumulated temperature.

This study aims to evaluate the efficacy of a digital medical library, including department-based electronic journal access, library training course participation and scholarly publications.

The data on full-text electronic journal access, participants of library training courses and scholarly publications were exported from a digital medical library database during 2017–2021. In addition, electronic journal access and library training courses were divided into high-level and low-level groups, while scholarly publications were divided into physician and non-physician groups.

The scholarly publications had a positive correlation to library training courses and electronic journal access. Furthermore, scholarly publications showed a significant difference between the high-level and low-level electronic journal access groups but not between the high-level and low-level library training course groups. Scholarly publications and electronic journal access had positive correlations for both the physician and non-physician groups. Scholarly publications and library training courses, and electronic journal access and library training courses had positive correlations only in the non-physician group.

The importance of electronic journal access for scholarly publications is suggested based on the findings of the present study. The training courses held by the medical library had a positive effect on scholarly publications for the non-physician group.

The current study provides insights relevant to the electronic journal access of library-supported scholarly publications among medical departments. These results can serve as a reference for medical library development planning and decision-making in the future.

The United Nations Sustainable Development Goals (SDGs) have urged retail companies to transform by adopting more sustainable practices. One of the key goals is to motivate responsible consumption and production. How to facilitate sustainable consumption of retail consumers is a research question of high theoretical and practical relevance. This research investigates the drivers of less examined sustainable consumer behaviour (reuse) from the perspective of consumers by integrating a value-based adoption model and the theory of planned behaviour (TPB).

Two samples of data were collected by using offline and online surveys. The offline survey was conducted at a university in northern Taiwan emphasizing sustainability practices. The online survey was implemented by a market research firm. A total of 518 useable questionnaires were obtained for data analysis by using the structural equation modelling.

Consistent with TPB, perceived behavioural control, subjective norms, and attitude, generate reuse intention in retail stores. Furthermore, the results also show the validity of the value adoption approach in predicting reuse intention in retail stores. Economic benefits and identity expressiveness are key facilitators and perceived inconvenience is a key barrier to perceived value and perceived value influences reuse intention in retail stores.

This research contributes by moving beyond TPB and proposing a value-based adoption approach to explain sustainable consumer behaviour in retail stores from the consumer perspectives. Based on the findings, value adoption strategies for retailers to facilitate sustainable consumer behaviour are proposed.

The purpose of this paper is to clarify the relationship between ethical leadership and employee organizational citizenship behavior (OCB), specifically the mechanisms through which ethical leadership impacts employee OCB, and the moderating role of workplace ostracism.

The study used the survey-based dyad data collected from middle management team members and their immediate subordinates in Chinese companies. Multiple regression analysis was used to test the research hypothesis.

The empirical findings indicate that ethical leadership positively influences employee OCB. Organizational commitment mediates the relationship between ethical leadership and employee OCB. Furthermore, the effect of ethical leadership on employee OCB directly and indirectly (via organizational commitment) is moderated by workplace ostracism.

This paper adds to knowledge about the relationship between ethical leadership and employee OCB and contributes to better understand workplace ostracism.

This study aims to develop a green, economical and efficient ultrasonic-/microwave assisted extraction (UMAE) process for the extraction of anthocyanins.

After optimizing the extraction conditions by response surface methodology, three assays including DPPH, ABTS·+, FRAP were applied to analyze the antioxidant activity of the extracted anthocyanins. The stability under different temperatures, reductant concentrations and pHs was also discussed. The components of anthocyanins in blueberry were analyzed by HPLC-QTOF-MS2.

The optimal extraction parameters were ultrasonic power of 300 W, microwave power of 365.28 W and solid–liquid ratio of 30 (g/mL). The possible structures can be speculated as Delphinidin-3-O-galactoside, Delphinidin, Petunidin, Delphinidin-3-O-glucoside, Petunidin-3-O-glucoside, Cyanidin-3-O-glucoside. The results demonstrated that the UMAE can improve the yield of anthocyanins in shorter extraction time with higher activity.

The present study may provide a promising and feasible route for extracting anthocyanins from blueberries and studying their physicochemical properties, ultimately promoting the utilization of blueberry anthocyanins.

This paper reviews the literature on zombie firms to provide a holistic view by delineating their formation, impact, widespread nature, prevention and policy implications.

This paper uses a systematic literature review methodology, in which 76 papers published in journals ranked on the Australian Business Deans Council (ABDC) 2022 list were reviewed. The study period was from 2000 to 2022.

Among the main findings, the widespread problems of zombie firms were evident. The authors found that consistent support, either in the form of government grants or a weak financial framework, was responsible for their formation. The suboptimal performance of factors of production, depressed job creation, low innovation and overall negative impact on economic activity are the consequences of zombification. This can be controlled by ensuring better bankruptcy codes, focused on government assistance, technology use and better due diligence by banks.

This review serves as a reference point for future researchers as a cohesive and holistic study presenting a full picture of the problem, so that the proposed solutions are robust and tenable.

This review is among the initial attempts to comprehensively study published work on zombie firms in terms of analyzing their region-specific nature, with an emphasis on definition, causes, impact and prevention.

This paper aims to study the issues of output reachable set estimation for the linear singular Markovian jump systems (SMJSs) with time-varying delay based on a proportional plus derivative (PD) bumpless transfer (BT) output feedback (OF) control scheme.

To begin with, a sufficient criterion is given in the form of a linear matrix inequality based on the Lyapunov stability theory. Then, a PD-BT OF controller is designed to keep all the output signs of the system are maintain within a predetermined ellipsoid. Finally, numerical and practical examples are used to demonstrate the efficiency of the approach.

Based on PD control and BT control method, an OF control strategy for the linear SMJSs with time-varying delay is proposed.

The output reachable set synthesis of linear SMJSs with time-varying delay can be solved by using the proposed approach. Besides, to obtain more general results, the restrictive assumptions of some parameters are removed. Furthermore, a sufficiently small ellipsoid can be obtained by the design scheme adopted in this paper, which reduces the conservatism of the existing results.

This paper aims to study the synergistic effect of graphene sponge on the thermal properties and shape stability of composite phase change material (PCM).

Graphene oxide sponge is first prepared from an aqueous solution of graphene oxide by freeze-drying method. The oxidized graphene sponge is reduced by hydrazine hydrate. Finally, use vacuum impregnation method to introduce paraffin into graphene sponge to prepare composite PCM.

Graphene sponge is used to improve the shape stability of paraffin wax and improves the thermal conductivity and latent heat of the composite PCM. The thermal conductivity increases by 200 per cent and the composite PCM has excellent reliability in 100 melt-freezing cycles.

A simple way for fabricating composite PCM with high thermal conductivity and latent heat which has the potential to be used as thermal storage materials without container encapsulation has been developed by using graphene sponge and paraffin.

The materials and preparation methods with special structure and properties in this paper provide a new idea for the research of PCM, which can be widely used in the fields of energy conversion and storage.
