This study aimed to find out whether working capital management policies affect the profitability of manufacturing companies listed on the Qatar Stock Exchange.

To assess the working capital management and profitability relationship, the authors applied a multiple regression analysis methodology in all manufacturing companies listed on the Qatar Stock Exchange (ten firms) between 2015 and 2019. Average collection period, inventory turnover, average payment period and cash conversion cycle were adopted as proxies for working capital management, and profitability was measured by operating profit margin (OPM), return on assets (ROA), return on capital employed (ROCE) and return on equity (ROE).

The study found that companies with shorter receivables collection periods and cash conversion cycles are more profitable. Longer inventory turnover periods and accounts payable payment periods are related to higher profitability of the firms.

Previous studies have assessed the relationship between working capital management and profitability. However, this study is the first one to use these four variables combined (OPM, ROA, ROCE and ROE) to measure profitability; this is what was limited in previous studies. In comparison, the previous studies were not comprehensive in studying the impact of working capital management on profitability from all aspects of profitability's variables [operational (OPM), economic (ROA), capitalist (ROCE) and financial (ROE)]. However, this study focused on all these aspects to make the results of the study more accurate. Also, it is worth mentioning that this study is the first research performed on Qatar Stock Exchange, although Qatar has achieved remarkable progress in the industrial sector in recent years, making it one of the first industrialized countries in the Middle East.

This study aims to examine why and when employees engage in creative deviance to develop creativity in China. Drawing on strain theory, the authors examined creative deviance engagement as a mediator and transformational leadership as a moderator of the distinct relationships between emotional and rational status-striving orientations and radical and incremental creativity.

Multisource survey data were collected from 126 team leaders and 446 employees in Chinese firms. Multilevel path analysis was used to test the hypotheses.

The results show that emotional status-striving orientation relates to creative deviance engagement, which, in turn, has a stronger relationship with radical creativity than with incremental creativity. Furthermore, creative deviance engagement mediates the indirect relationships between emotional status-striving orientation and radical and incremental creativity. Moreover, transformational leadership moderates the above indirect relationships.

This study is among the first attempts to empirically test the distinct relationships between creative deviance engagement and radical and incremental creativity and further examine how creative deviance engagement mediates the indirect relationships between status-striving orientations and radical and incremental creativity. In addition, the boundary condition of the indirect relationships is investigated. The findings provide valuable insights for the extant literature on status and employee creativity.

Tingting Qi's chapter titled, “Moving toward Decentralization? Changing Education Governance in China After 1985,” provides the historical and policy context for the volume. This chapter integrates the post-1978 Chinese educational reforms into the socioeconomic context of China. The special contribution of this chapter is that it explores the complexity of educational decentralization in China through an in-depth analysis of changes in education finance, administration, and curriculum. Qi reviews prior studies, government documents, laws, and regulations related to Chinese education reform since 1978 within the context of education decentralization in China. Qi also demonstrates that China's educational policy reforms are moving China toward “centralized decentralization” because decentralization is driven by a common, centralized national goal of economic modernization. The chapter presents evidence that “centralized decentralization” is a strategic maneuver that maintains centralized control while providing the reform legitimacy of decentralization. By focusing on decentralization as the core of Chinese educational policy reforms, this chapter situates the following chapters within the social, cultural, and political context of post-1978 China.

This paper aims to investigate how online consumer reviews (OCRs), countdowns and self-control affect consumers' online impulse buying behavior in online group buying (OGB) and uncover the relationship between these factors.

Based on the stimulus-organism-response (SOR) framework, this research examines the effects of OCRs, countdowns and self-control on users' impulse purchases. First, the influence of emotions on impulse purchases in group purchasing is investigated. In addition, this study innovatively applies stress-coping theory to group buying research, with countdowns exerting temporal pressure on consumers and OCRs viewed as social pressure, to investigate in depth how countdowns and OCRs affect users' impulse purchase behavior. Finally, this study also surveys the moderating role of users' self-control in the impulse purchase process.

The results show that the perceived value of OCRs and positive emotions (PE) were positively correlated with impulsiveness (IMP) and the urge to buy impulsively (UBI), while negative emotions (NE) were negatively correlated with IMP. Countdowns (CD) had a positive effect on UBI. Self-control can indirectly affect users' impulse buying by negatively moderating the relationship between PE and UBI, PE and IMP and CD and UBI.

The research results can help group buying platforms and related participants understand the factors influencing users' impulse purchases in OGB and facilitate them to better design strategies to increase product sales.

Twitter fake accounts refer to bot accounts created by third-party organizations to influence public opinion, commercial propaganda or impersonate others. The effective identification of bot accounts is conducive to accurately judge the disseminated information for the public. However, in actual fake account identification, it is expensive and inefficient to manually label Twitter accounts, and the labeled data are usually unbalanced in classes. To this end, the authors propose a novel framework to solve these problems.

In the proposed framework, the authors introduce the concept of semi-supervised self-training learning and apply it to the real Twitter account data set from Kaggle. Specifically, the authors first train the classifier in the initial small amount of labeled account data, then use the trained classifier to automatically label large-scale unlabeled account data. Next, iteratively select high confidence instances from unlabeled data to expand the labeled data. Finally, an expanded Twitter account training set is obtained. It is worth mentioning that the resampling technique is integrated into the self-training process, and the data class is balanced at the initial stage of the self-training iteration.

The proposed framework effectively improves labeling efficiency and reduces the influence of class imbalance. It shows excellent identification results on 6 different base classifiers, especially for the initial small-scale labeled Twitter accounts.

This paper provides novel insights in identifying Twitter fake accounts. First, the authors take the lead in introducing a self-training method to automatically label Twitter accounts from the semi-supervised background. Second, the resampling technique is integrated into the self-training process to effectively reduce the influence of class imbalance on the identification effect.

This paper aims to develop a theoretical model to understand co-creation/co-destruction of value through customer engagement in online channels. It also investigates the contributing factors.

The qualitative approach uses the critical incidents technique to answer the research questions. The authors identify 350 critical incidents in which customers expressed online customer engagement-induced value co-creation or co-destruction experiences. The factors and resulting propositions are identified through data analysis. Data coding and analysis are facilitated by using MAXQDA 12.

Co-creation through positively valenced engagement behaviors may occur when customers are delighted, feel valued, experience reciprocity, receive organizational incentives, are solicited for feedback, can count on service recovery efforts and interact with helpful, empathetic, polite and responsive employees. Co-destruction through negatively valenced engagement behaviors emerges from rude employee behaviors, indifference, confrontation with company representatives, technological failure, the lack of complaint outlets and customers’ desire for revenge.

Selecting and training employees to be helpful, polite, responsive and empathetic toward online visitors can trigger co-creation. Communication between firms and customers should boost customer approval and delight. Organizations can offer incentives, reliable service delivery and a recovery design to stimulate visitor participation. Soliciting feedback requires sound technological support and direct communication links with visitors.

This study presents the conditions and framework contributing to the duality of customer engagement-induced co-creation and co-destruction values in online channels from the customer, organizational, employee, service design and technological perspectives. It also addresses how value is co-created or co-destructed through examples.

Improving the agricultural products market integration is conducive to developing provincial comparative advantage, optimization of agricultural and industrial organization and enhanced competitiveness. The relationship between the emergencies and the agricultural products market integration in the production and consumption provinces is of great significance for stabilizing market prices and improving the efficiency of agricultural resource allocation.

The authors reviewed the literature on the market integration of agricultural products. Then, they adopted a two-way fixed effect model to investigate the impact of emergencies on the poultry market integration in the production and consumption provinces in China.

Highly pathogenic avian influenza (HPAI) caused abnormal fluctuations in the poultry market price and decreased the poultry market integration. The negative impact of HPAI on poultry market integration was strengthened in the main production provinces and weakened in the main consumption provinces.

This is the first study that applies empirical analysis to identify the emergencies’ impact on the poultry market integration considering production and consumption characteristics. The results indicate that the impact of avian influenza is more serious in production provinces than in consumption provinces. Due to the heterogeneity of production and consumption provinces, the government implements precise compensation policies to resume production quickly after the disaster. It can be conductive to market integration and promote the development of agricultural products market.

This study aims to make some contribution to the process of corporate compliance governance in China.

This paper adopts qualitative method, literature research, case analysis and comparative methods to explore the Chinese compliance governance model in the field of collusive bidding crimes.

In the process of criminal prosecution of enterprises suspected of committing crimes, the judicial authorities should promote the restoration of normal production and operation of corporate enterprises by promoting the construction of corporate compliance, which is conducive to solving the difficult problem of attribution of collusive bidding crimes. In addition, corporate compliance under prosecutorial supervision is also conducive to optimizing the regulatory path of collusive bidding and achieving more effective prevention and control of unit crimes in the mode of co-regulation between the state and corporate.

Compliance governance corporate crime is at a nascent stage in China, and this study seeks to provide some reference for future compliance review governance in China through the analysis of specific business crime cases.

This paper explores the association between directors’ and officers’ liability insurance (D&O insurance) and management tone manipulation.

This study uses data from A-share listed non-financial companies from 2009 to 2021 as its sample for empirical tests. In addition, the study relies on text analysis and the construction of models to investigate the relationship between D&O insurance and management tone manipulation.

The authors find that the purchase of D&O insurance will lead to management tone manipulation in the “management discussion and analysis” part of companies’ annual reports, and operating risk and agent cost are the two paths for the effect. Further analysis shows that having a male CEO and employing high-quality auditors can weaken the positive impact of D&O insurance on tone manipulation.

This paper provides a new approach for studying the literature related to D&O insurance and management behavior, and the findings enrich our understanding of the influencing factors and the mechanism of management tone manipulation, thus revealing policy implications for further standardization of the terms and system of D&O insurance in China.

The purpose of this paper is to eliminate Part defects and enrich additive manufacturing of ceramics. Laser powder bed fusion (L-PBF) experiments were carried to investigate the effects of laser parameters and selective oxidation of Titanium (mixed with TiO₂) on the microstructure, surface quality and melting state of Titania. The causes of several L-PBF parts defects were thoroughly analyzed.

Laser power and scanning speed were varied within a specific range (50–125 W and 170–200 mm/s, respectively). Furthermore, varying loads of Ti (1%, 3%, 5% and 15%) were mixed with TiO₂, which was selectively oxidized with laser beam in the presence of oxygen environment.

Part defects such as cracks, pores and uneven grains growth were widely reduced in TiO₂ L-PBF specimens. Increasing the laser power and decreasing the scanning speed shown significant improvements in the surface morphology of TiO₂ ceramics. The amount of Ti material was fully melted and simultaneously changed into TiO₂ by the application of the laser beam. The selective oxidation of Ti material also improved the melting condition, microstructure and surface quality of the specimens.

TiO₂ ceramic specimens were produced through L-PBF process. Increasing the laser power and decreasing the scanning speed is an effective way to sufficiently melt the powders and reduce parts defects. Selective oxidation of Ti by a high power laser beam approach was used to improve the manufacturability of TiO₂ specimens.
