Abstract

Purpose

The purpose of this paper is to solve the shortage of the existing methods for the prediction of network security situations (NSS). Because the conventional methods for the prediction of NSS, such as support vector machine, particle swarm optimization, etc., lack accuracy, robustness and efficiency, in this study, the authors propose a new method for the prediction of NSS based on recurrent neural network (RNN) with gated recurrent unit.

Design/methodology/approach

This method extracts internal and external information features from the original time-series network data for the first time. Then, the extracted features are applied to the deep RNN model for training and validation. After iteration and optimization, the accuracy of predictions of NSS will be obtained by the well-trained model, and the model is robust for the unstable network data.

Findings

Experiments on bench marked data set show that the proposed method obtains more accurate and robust prediction results than conventional models. Although the deep RNN models need more time consumption for training, they guarantee the accuracy and robustness of prediction in return for validation.

Originality/value

In the prediction of NSS time-series data, the proposed internal and external information features are well described the original data, and the employment of deep RNN model will outperform the state-of-the-arts models.

Abstract

Purpose

The purpose of this paper is to test the factor structure of the multifactor leadership questionnaire (MLQ) in the Chinese context and determine whether leader-member exchange (LMX) mediates the effects of active constructive leadership (ACL) and passive corrective leadership (PCL) on subordinates’ organizational commitment at the group level.

Design/methodology/approach

Questionnaires were completed by two employee samples. The first sample consisted of 615 employees from five pharmaceutical companies. The second sample consisted of 676 employees from 144 teams. Exploratory factor analysis, confirmatory factor analysis and structural equation modeling were used to test the hypotheses.

Findings

The factor analysis results showed two types of leadership in the data: ACL and PCL. The structural equation modeling showed that LMX mediated the effect of leadership on collective organizational commitment.

Research limitations/implications

The data were cross-sectional in nature. Furthermore, leadership and LMX were both measured from the perspective of followers.

Practical implications

Managers must realize that leadership is an art that requires not only the self-cultivation of individual behavior, but also appropriate and intelligent conduct when interacting with followers. Team leaders also must pay attention to both their high quality relationships with subordinates and the mutual influence within their groups.

Originality/value

The current study makes an empirical contribution to the psychometric properties of the MLQ, suggesting a higher two-factor structure appropriate for Chinese employees. It also clarifies the relationships between leadership, LMX and organizational commitment at multiple levels.

Abstract

Purpose

This study examined the link between abusive supervision and subordinates’ turnover intentions via job dissatisfaction. In addition, this study examined the moderating effect of continuance commitment in this process.

Design/methodology/approach

The authors collected three-wave time lagged data (N = 190) from the hospitality industry in China.

Findings

The analysis showed that abusive supervision predicts subordinates’ turnover intentions both directly and indirectly via job dissatisfaction. Moreover, continuance commitment was considered to be a boundary condition such that the mediated link was weaker when higher levels of continuance commitment were present.

Practical implications

This study explains how and when abusive supervision leads to turnover intentions in the hospitality industry. This study also helps hospitality managers to understand the abusive supervision prevalence and provide interventions that can reduce detrimental effects of abusive supervision in hospitality organizations.

Originality/value

Prior research examining the influence of supervisor abuse in hospitality organizations was scant. To bridge this noteworthy gap, this study examined the influence of abusive supervision in Chinese hospitality organizations. This study also discussed the theoretical and practical implications for the hospitality industry.

Abstract

Purpose

This paper takes listed companies in the Shanghai and Shenzhen stock markets from 1998 to 2013 as a research sample, investigating the role played by corruption and financial development, along with the interactions between the two, in determining the factors of a company’s capital structure in China’s legal environment. The paper aims to discuss these issues.

Design/methodology/approach

Using data of listed companies and the regional level of China during 1998-2013 and the STATA process (xtabond2 command) developed by Roodman (2006) to implement the two-step GMM estimation, empirically investigate the effect of interactions between corruption and financial development on a company’s capital structure in Chinese legal environment.

Findings

After both controlling for China’s legal environment, a company’s internal factors, and industry factors and considering endogeneity problems, the results show that corruption and financial development have significant positive influences on a company’s bank loans. However, when investigating the interactions between corruption and financial development, the authors find that financial development does not increase a company’s bank loans in areas with a higher level of corruption. However, corruption and financial development have insignificant influences on a company’s long-term bank loans.

Research limitations/implications

The findings in this study suggest that a company’s capital structure was affected not only by the company’s internal factors and industry factors, but also by the company’s external factors, and the interactions between these factors.

Practical implications

To improve the financing circumstances of company credit, the next point of reform should be to improve their procedures for administrative examination and approval of bank creditors and strengthen the punishment and prevention of credit and judicial corruption to weaken the negative effects of corruption on firms’ capital structure decisions.

Originality/value

This study uses only Chinese listed companies, and considers the influence of the interaction of corruption and financial development on a company’s capital structure decisions.

Abstract

Purpose

First, this paper aims to explore how CEO humility and relationship conflict in entrepreneurial teams affect the firm-level performance of new ventures. Second, it investigates the moderating effect of CEO political skills on the indirect association between CEO humility and entrepreneurial performance through relationship conflict in entrepreneurial teams.

Design/methodology/approach

A questionnaire survey was administered to CEOs and their entrepreneurial team members in 171 start-ups in Shanghai, China. The data obtained from the survey were subjected to multiple regression analysis using the SPSS PROCESS macro and confirmatory factor analysis using Mplus.

Findings

The findings are as follows. First, CEO humility can reduce relationship conflict in entrepreneurial teams. Second, CEO political skills moderate the link between CEO humility and relationship conflict in entrepreneurial teams. The weaker the CEO political skills, the stronger the effect of CEO humility on relationship conflict, and the stronger the CEO political skills, the weaker the effect of CEO humility on relationship conflict. Third, relationship conflict in entrepreneurial teams is negatively related to entrepreneurial performance. Finally, CEO political skills moderate the mediating effect of entrepreneurial team relationship conflict on the CEO humility – entrepreneurial performance link.

Practical implications

The findings of this study offer guidance for entrepreneurs seeking to improve firm performance. The findings suggest that entrepreneurs should adopt a humble leadership style that cultivates their strengths and minimizes their weaknesses. To improve the centripetal force and cohesion of the entrepreneurial team, they should focus on the team, affirm the contribution of subordinates and accept subordinates’ advice.

Originality/value

The study reveals that CEO humility has a positive effect on entrepreneurial performance, which enriches research on the effectiveness of humble leadership at the firm level. From the perspective of team relationship conflict, the study also explores the mechanism underlying the effect of CEO humility on entrepreneurial performance, opening the “black box” of CEO humility and entrepreneurial effectiveness. In addition, the study reveals the boundary conditions of the influence of CEO humility, enriching the theoretical literature on humble leadership, political skills and resource conservation.

Abstract

Purpose

This paper aims to explore the possibility of converting the nitrile butadiene rubber (NBR) water-lubricated bearing material into a self-lubricating bearing material by the action of polytetrafluoroethylene (PTFE) particles and water lubrication.

Design/methodology/approach

A group of experimental studies was carried out on a ring-on-block friction test. The physical properties, tribological properties and interface structure of PTFE-NBR self-lubricating composites filled with different percentages of PTFE particles were investigated.

Findings

The experimental results indicated that the reduction in friction and wear is a result of the formation of the lubricating film on the surface of the composites. The lubricating film was formed of a large amount of PTFE particles continuously supplied under water lubrication conditions and the PTFE particles here can greatly enhance the load capacity and lubrication performance.

Originality/value

In this study, the tribological properties of PTFE particles added to the NBR water-lubricated bearing materials under water lubrication were investigated experimentally, and the research was carried out by a ring-on-block friction test. It is believed that this study can provide some guidance for the application of PTFE-NBR self-lubricating.

The purpose of this paper is to evaluate the impact of short-term loan (STL) vs long-term loan (LTL) on wheat productivity of small farms in Sindh, Pakistan.

Abstract

Purpose

The purpose of this paper is to evaluate the impact of short-term loan (STL) vs long-term loan (LTL) on wheat productivity of small farms in Sindh, Pakistan.

Design/methodology/approach

The econometric estimation is based on cross-sectional data collected in 2016 from 18 villages in three districts, i.e. Shikarpur, Sukkur and Shaheed Benazirabad, Sindh, Pakistan. The sample data set consist of 180 wheat farmers. The collected data were analyzed through different econometric techniques like Cobb–Douglas production function and Instrumental variables (two-stage least squares) approach.

Findings

This study reconfirmed that agricultural credit has a positive and highly significant effect on wheat productivity, while the short-term loan has a stronger effect on wheat productivity than the long-term loan. The reasons behind the phenomenon may be the significantly higher usage of agricultural inputs like seeds of improved variety and fertilizers which can be transformed into the wheat yield in the same year. However, the LTL users have significantly higher investments in land preparation, irrigation and plant protection, which may lead to higher wheat production in the coming years.

Research limitations/implications

In the present study, only those wheat farmers were considered who obtained agricultural loans from formal financial institutions like Zarai Taraqiati Bank Limited and Khushhali Bank. However, in the rural areas of Sindh, Pakistan, a considerable proportion of small-scale farmers take credit from informal financial channels. Therefore future researchers should consider the informal credits as well.

Originality/value

This is the first paper to examine the effects of agricultural credit on wheat productivity of small farms in Sindh, Pakistan. This paper will be an important addition to the emerging literature regarding effects of credit studies.

This paper aims to improve the corrosion resistance performance and stability of PbO2 electrodes in chloride wastewater.

Abstract

Purpose

This paper aims to improve the corrosion resistance performance and stability of PbO2 electrodes in chloride wastewater.

Design/methodology/approach

The morphology of PbO2-ZrO2 nanocomposite electrodes was observed by scanning electron microscopy (SEM). The open circuit potential (OCP) curves, anodic polarization curves, electrochemical impedance spectra, accelerated life tests, weight-loss tests and reusability tests were used to study the corrosion resistance properties and stability of PbO2-ZrO2 nanocomposite electrodes in NaCl solution.

Findings

SEM showed that the surface morphology of PbO2-ZrO2 nanocomposite electrodes became compacted and smooth. Electrochemical tests showed that ZrO2 nanoparticles could increase the OCP, corrosion potential and charge transfer resistance, and decrease the corrosion current density in 3.5 Wt. per cent NaCl electrolyte solution. Besides, PbO2-ZrO2 nanocomposite electrodes showed high reusability for acetamiprid degradation, the accelerated service life could reach 146 h, which was almost 3.3 times longer than that of PbO2 electrodes (44 h), weight-loss tests showed that the corrosion resistance for PbO2-ZrO2 nanocomposite electrodes was 2.3 times as compared to PbO2 electrodes.

Originality/value

By the codeposition of ZrO2 nanoparticles, the corrosion resistance performance and stability of PbO2 electrodes in NaCl electrolyte were improved.

Abstract

Purpose

The purpose of this paper is to define the conceptualization and measurement of informatization according to a capability perspective reflected in three aspects: IT managerial capability, IT-enabled capability and IT infrastructure capability.

Design/methodology/approach

Manufacturing enterprises in China’s Northeast and Pearl River Delta regions in China were selected to empirically examine, using structural equation modeling, the association between a firm’s senior executive support informatization and radical innovation performance.

Findings

Results show a significant positive relationship between senior executive support and IT-enabled capability. However, there are no significant positive influences uncovered between senior executive support and IT managerial capability and IT infrastructure capability. The authors find significant positive effects of IT managerial capability, IT-enabled capability and IT infrastructure capability on radical innovation performance. Lastly, the joint effect of senior executive support and external institutional environment has no significant influence on informatization.

Originality/value

This study offers improved understanding for enterprises and academia about the effect of senior executive support informatization on radical innovation performance. It also suggests taking effective measures to highlight the management level and enterprises’ radical innovation performance.
