Abstract
Purpose
Accurate prediction of seasonal power consumption trends with impact disturbances provides a scientific basis for the flexible balance of the long timescale power system. Consequently, it fosters reasonable scheduling plans, ensuring the safety of the system and improving the economic dispatching efficiency of the power system.
Design/methodology/approach
First, a new seasonal grey buffer operator in the longitudinal and transverse dimensional perspectives is designed. Then, a new seasonal grey modeling approach that integrates the new operator, full real domain fractional order accumulation generation technique, grey prediction modeling tool and fruit fly optimization algorithm is proposed. Moreover, the rationality, scientificity and superiority of the new approach are verified by designing 24 seasonal electricity consumption forecasting approaches, incorporating case study and amalgamating qualitative and quantitative research.
Findings
Compared with other comparative models, the new approach has superior mean absolute percentage error and mean absolute error. Furthermore, the research results show that the new method provides a scientific and effective mathematical method for solving the seasonal trend power consumption forecasting modeling with impact disturbance.
Originality/value
Considering the development trend of longitudinal and transverse dimensions of seasonal data with impact disturbance and the differences in each stage, a new grey buffer operator is constructed, and a new seasonal grey modeling approach with multi-method fusion is proposed to solve the seasonal power consumption forecasting problem.
Highlights
The highlights of the paper are as follows:
A new seasonal grey buffer operator is constructed.
The impact of shock perturbations on seasonal data trends is effectively mitigated.
A novel seasonal grey forecasting approach with multi-method fusion is proposed.
Seasonal electricity consumption is successfully predicted by the novel approach.
The way to adjust China's power system flexibility in the future is analyzed.

Abstract
Purpose
The purpose of this study is to advance and test a new construct, harmony voice. Furthermore, according to the social influence theory, the relationship between zhongyong, an essential Confucian orientation mode and voice behavior, and the moderating role of coworker’s regulatory focus (promotion focus and prevention focus) has been examined.
Design/methodology/approach
A field study has been designed to test our hypotheses. We used samples of 291 employee–coworker dyads from a variety of organizations in China to test this study’s hypotheses.
Findings
The results of this empirical study show that zhongyong is positively related to harmony voice. Coworkers’ promotion focus strengthens the positive effect of zhongyong on harmony voice, and coworkers’ prevention focus weakens the positive effect of zhongyong on harmony voice.
Research limitations/implications
Traditionally defined voice and harmony voice might cause different risks to the voicer. However, how and what kinds of risks may be differently caused by these two types of voice behaviors have not been examined in this study. Future empirical research can explore the different effects of traditionally defined voice and harmony voice.
Practical implications
Managers responsible for managing Chinese employees should notice the difference in some important ways of thinking between Easterners and Westerners. Specifically, zhongyong may direct people to express issues related to work in ways that are different from those of their Western counterparts. Harmony voice can benefit the Chinese organization without disrupting organizational development.
Social implications
By examining the relationship between zhongyong and harmony voice, we contribute to identifying antecedents of voice by using an emic research perspective.
Originality/value
We made significant theoretical contributions to voice literature. We developed the construct of harmony voice, and we examined the relationship between zhongyong and voice.

Abstract
Purpose
Drawing on engagement theory, this study aims to examine how leader–member relationships, including on-work relationship (leader–member exchange [LMX]) and off-work relationship (leader–member guanxi [LMG]), influence employees’ promotive and prohibitive voice. Furthermore, the study uses procedural justice as the moderator to distinguish the effects of LMG and LMX on employees’ psychological states and voice through a mediated moderation model.
Design/methodology/approach
The authors use a sample from a private and local company in Southern China to test their theoretical model.
Findings
The study finds that both LMG and LMX have positive effects on employees’ voice behavior through employees’ psychological states (psychological meaningfulness and psychological safety).
Research limitations/implications
In a Chinese context, leaders have a more direct and powerful influence on employees than their counterparts in the Western society. Thus, the findings of LMX and LMG may not be generalizable to a Western context. A possible extension is to examine and compare the effects of social context (e.g., off-work leader–member relationship) on voice between the East and the West.
Practical implications
One important implication is that off-work relationship should be used by managers to encourage employee voice.
Originality/value
This study enriches the antecedents of voice with a new dimension of leader–member relationship, namely, LMG.

Abstract
Purpose
This study aims to explore the cross-level effect of the top management team (TMT) on group ambidextrous innovation and to analyze the mediating role of group behavioral integration and the moderating effect of group expertise heterogeneity.
Design/methodology/approach
We conducted a multi-source and multi-stage survey. We collected valid data from 43 companies in China, resulting in 141 samples from 43 TMTs and 462 valid responses from 111 organizational groups. The proposed theoretical model and hypotheses were tested using structural equation modeling.
Findings
The study findings demonstrated that TMT behavioral integration was positively related to group behavioral integration. Group behavioral integration mediates the relationship between TMT behavioral integration and these two types of innovations. Furthermore, we found that group expertise heterogeneity magnified the positive effect of group behavioral integration on exploratory innovation.
Originality/value
This study reveals the cross-level effects of TMT behavioral integration on other organizational groups and enriches the existing literature on TMT behavioral integration and ambidextrous innovation.

This study aims to develop a green, economical and efficient ultrasonic-/microwave assisted extraction (UMAE) process for the extraction of anthocyanins.
Abstract
Purpose
This study aims to develop a green, economical and efficient ultrasonic-/microwave assisted extraction (UMAE) process for the extraction of anthocyanins.
Design/methodology/approach
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.
Findings
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.
Originality/value
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.

Abstract
Purpose
The purpose of this study is to explore the relationship between supervisor and coworkers’ workplace incivility and newcomer proactive behaviors. Drawing on conservation of resources (COR) theory, the authors examined resource depletion as a mediator and newcomer proactive personality, as well as their current organizational tenure as moderators of the relationship between workplace incivility toward newcomers and their proactive behaviors.
Design/methodology/approach
A time-lagged research design was used to test hypotheses with data covering 322 newcomers and their immediate supervisors in two subsidiaries of a large food processing company in China. Regression analysis using the PROCESS macro in SPSS is used to test the hypotheses.
Findings
The results show that workplace incivility toward newcomers is negatively related to their proactive behaviors. This relationship is mediated by resource depletion. Furthermore, newcomers’ proactive personality moderates the relationship between workplace incivility and resource depletion. Moreover, both the direct effect of workplace incivility on resource depletion and its indirect effect on newcomer proactive behaviors are moderated by the combination of newcomer proactive personality and their current organizational tenure.
Originality/value
Drawing on COR theory, a theoretical framework is constructed that specifies the process through which workplace incivility affects proactive behaviors to expand collective understandings of workplace incivility in the newcomer context. Furthermore, the boundary conditions of the underlying process are investigated, which further enhances the contribution of this paper to the extant literature on workplace incivility.

Abstract
Purpose
Drawing on ego depletion theory, this study aims to provide insights into the effect of work-family conflict on the high-speed railway (HSR) drivers’ safety performance by examining the mediating role of ego depletion and the moderating roles of work-family centrality and supervisor safety support.
Design/methodology/approach
In total, 243 HSR drivers from 7 railway bureaus in China were surveyed. Structural equation modeling was used to test the hypotheses.
Findings
Both work-to-family conflict and family-to-work conflict have direct and positive effects on HSR drivers’ ego depletion and indirect effects on both safety compliance and safety participation via ego depletion. Moreover, both the direct effect of work-family conflict on ego depletion and its indirect effect on safety performance are moderated by work-family centrality. Supervisor safety support plays a buffering role in the relationship between ego depletion and safety performance.
Originality/value
This study examined the relationship between work-family conflict and safety performance based on the perspective of ego depletion theory. The findings testify to the importance of reducing work-family conflict among HSR drivers pursuant to maximizing safety.

Abstract
Purpose
The rapid urbanization of China brings in large number of migrant workers coming from rural areas. With the perspective of social integration, this study reviews the findings about economic livelihood, social integration and health related to migrant workers since China initiated economic reform. We show that (1) though the economic wellbeing of migrant workers has been improved significantly after they moved to cities, their economic standing is still lower than local residents; (2) though there is progress of social integration between migrant workers and local residents, conflicts and challenges due to the competitions in employment and the sharing of community resource are still commonly found; (3) the disadvantaged status of health is very common among migrant workers and (4) women and the new generation in migration have more disadvantages in the social transition. We suggest that issues of equal rights between migrant workers and local residents should be discussed in the future as more migrant workers intend to stay in cities for long-term.
Design/methodology/approach
The methodology is literature reviews based on the current studies about migrant, migration and policy. The first category of literature is the research field on China's migration and urbanization to describe the whole context of migrant workers. The second is research field on detailed issues about migrant workers and the last field is policy issues about the welfare and needs among migrant workers.
Findings
We find that (1) though the economic wellbeing of migrant workers has been improved significantly after they moved to cities, their economic standing is still lower than local residents; (2) though there are progress of social integration between migrant workers and local residents, conflicts and challenges due to the competitions in employment and the sharing of community resource are still commonly found; (3) the disadvantaged status of health is very common among migrant workers and (4) women and the new generation in migration face more disadvantages in the social transition.
Research limitations/implications
There are some limitations in the current research: (1) the review focuses on the majority of migrant workers to reveal the general picture about the living, developing and rights among migrant workers, but is still lacking in dealing with some special and disadvantaged groups. (2) More international issues related to migrant workers should be discussed in the future considering that China's labor market is becoming more and more global.
Social implications
First, the conclusion about the economic and social integration among migrant workers indicates that more equal welfare services, including resident services, commence services, medical services etc. should be included in the municipal managements considering that Chinese cities will be the combination of local residents and migrant residents. Second, the conclusion about the women and children indicates that the future public services targeted at the disadvantaged population should focus on migrant members due to the second generation of migrant workers will be one of the mainstream population in future China's cities.
Originality/value
This study gives general views on migrant workers in current China. The findings in this review conclude the main development and improvements among tens of millions of migrant workers in Chinese cities. Meanwhile, we also conclude that there are still many disadvantaged and marginalized sub-groups in migration who are suffering from less welfares and rights in urban lives. More detailed and equal rights and public services should be considered and implemented in the fast urbanization taking place.

Abstract
Purpose
This study proposes low-carbon technology (LCT) solutions from the perspective of incremental cost-effectiveness and public satisfaction based on calculating carbon emissions and economic costs.
Design/methodology/approach
According to the citation frequency, 11 indicators of low-carbon neighborhood (LCN) were selected so as to construct the low-carbon renewal potential evaluation model. Five neighborhoods were selected to evaluate low-carbon renewal potential based on the driving-pressure-state-impact-response (DPSIR). Moreover, the neighborhoods with the highest renewal potential were selected for further analysis. Then, the feasibility decision was carried out among seven typical LCTs based on the value engineering (VE) method. Finally, the TOPSIS method was applied to calculate the public satisfaction and demand so as to get the priorities of these LCTs. Through comprehensive analysis, the final LCT solutions could be carried out.
Findings
Our practice proves that the evaluation model combined with the decision-making methods can provide scientific decision-making support for the LCT solutions. Some LCTs perform consistently across different neighborhoods by comparing VE results and TOPSIS rankings. The solar photovoltaic (PV) (T3) has high value and significant attention which gives it a top priority for development, while the energy-efficient windows and doors (T2) have relatively low value.
Originality/value
There is a lack of research that considers the economic cost, low-carbon efficiency and public satisfaction when proposing LCT solutions for neighborhood renewal projects. Faced with the problem, we practice the decision-making from two dimensions, that is, the “feasibility decision with VE” and the “priorities decision with TOPSIS.” In this way, a balance between incremental cost-effectiveness and public satisfaction is achieved, and LCT solutions are proposed.
