Abstract

Purpose

As cyber-attacks continue to grow, organisations adopting the internet-of-things (IoT) have continued to react to security concerns that threaten their businesses within the current highly competitive environment. Many recorded industrial cyber-attacks have successfully beaten technical security solutions by exploiting human-factor vulnerabilities related to security knowledge and skills and manipulating human elements into inadvertently conveying access to critical industrial assets. Knowledge and skill capabilities contribute to human analytical proficiencies for enhanced cybersecurity readiness. Thus, a human-factored security endeavour is required to investigate the capabilities of the human constituents (workforce) to appropriately recognise and respond to cyber intrusion events within the industrial control system (ICS) environment.

Design/methodology/approach

A quantitative approach (statistical analysis) is adopted to provide an approach to quantify the potential cybersecurity capability aptitudes of industrial human actors, identify the least security-capable workforce in the operational domain with the greatest susceptibility likelihood to cyber-attacks (i.e. weakest link) and guide the enhancement of security assurance. To support these objectives, a Human-factored Cyber Security Capability Evaluation approach is presented using conceptual analysis techniques.

Findings

Using a test scenario, the approach demonstrates the capacity to proffer an efficient evaluation of workforce security knowledge and skills capabilities and the identification of weakest link in the workforce.

Practical implications

The approach can enable organisations to gain better workforce security perspectives like security-consciousness, alertness and response aptitudes, thus guiding organisations into adopting strategic means of appropriating security remediation outlines, scopes and resources without undue wastes or redundancies.

Originality/value

This paper demonstrates originality by providing a framework and computational approach for characterising and quantify human-factor security capabilities based on security knowledge and security skills. It also supports the identification of potential security weakest links amongst an evaluated industrial workforce (human agents), some key security susceptibility areas and relevant control interventions. The model and validation results demonstrate the application of action research. This paper demonstrates originality by illustrating how action research can be applied within socio-technical dimensions to solve recurrent and dynamic problems related to industrial environment cyber security improvement. It provides value by demonstrating how theoretical security knowledge (awareness) and practical security skills can help resolve cyber security response and control uncertainties within industrial organisations.

Abstract

Purpose

The purpose of this paper is to propose a fault diagnosis method for rolling bearings, in which the fault feature extraction is realized in a two-dimensional domain using scale invariant feature transform (SIFT) algorithm. This method is different from those methods extracting fault feature directly from the traditional one-dimensional domain.

Design/methodology/approach

The vibration signal of rolling bearings is first transformed into a two-dimensional image. Then, the SIFT algorithm is applied to the image to extract the scale invariant feature vector which is highly distinctive and insensitive to noises and working condition variation. As the extracted feature vector is high-dimensional, kernel principal component analysis (KPCA) algorithm is utilized to reduce the dimension of the feature vector, and singular value decomposition technique is used to extract the singular values of the reduced feature vector. Finally, these singular values are introduced into a support vector machine (SVM) classifier to realize fault classification.

Findings

The experiment results show a high fault classification accuracy based on the proposed method.

Originality/value

The proposed approach for rolling bearing fault diagnosis based on SIFT-KPCA and SVM is highly effective in the experiment. The practical value in engineering application of this method can be researched in the future.

Abstract

Purpose

The primary purpose of this study is to investigate the image transfer and its effects on exhibitors’ behavioral intention. Specifically, the study attempted to examine the effect of mega business event image on destination and country image from exhibitors’ perspective and the effect of mega business event image on exhibitors’ behavioral intention toward the event.

Design/methodology/approach

The data for this study were collected through an on-site survey. Based on a sample of 393 respondents, structural equation modeling was used to test the proposed hypotheses.

Findings

The results showed that business event image has a stronger effect on country image than on destination image; event image has a significant effect on exhibitor’s behavioral intention toward the event directly and indirectly through the mediating role of country image; and country image has a significant influence on destination image.

Practical implications

The event organizer should improve the exhibitor’s perceptions of the event experience from providing a clear and attractive theme for the target audiences; exhibiting the products with the most cutting-edge technologies and offering various opportunities for forums and promotions; and planning and organizing the event in every detail carefully including the facilities, layout of booths, ambience and other related services.

Originality/value

The study expands the event type to business events, explores the image transfer process between event, destination and country and examines the effects of such image transfer on the exhibitors’ behavioral intention. The results confirm the explanatory power of image transfer theory. Attribution theory and halo effect are viewed as the mechanisms of image transfer.

Abstract

Purpose

The purpose of this paper is to study the evolution and growth of aerosol particles in a turbulent planar jet by using the newly developed large eddy simulation (LES)-differentially weighted operator splitting Monte Carlo (DWOSMC) method.

Design/methodology/approach

The DWOSMC method is coupled with LES for the numerical simulation of aerosol dynamics in turbulent flows.

Findings

Firstly, the newly developed and coupled LES-DWOSMC method is verified by the results obtained from a direct numerical simulation-sectional method (DNS-SM) for coagulation occurring in a turbulent planar jet from available literature. Then, the effects of jet temperature and Reynolds number on the evolution of time-averaged mean particle diameter, normalized particle number concentration and particle size distributions (PSDs) are studied numerically on both coagulation and condensation processes. The jet temperature and Reynolds number are shown to be two important parameters that can be used to control the evolution and pattern of PSD in an aerosol reactor.

Originality/value

The coupling between the Monte Carlo method and turbulent flow still encounters many technical difficulties. In addition, the relationship between turbulence, particle properties and collision kernels of aerosol dynamics is not yet well understood due to the theoretical limitations and experimental difficulties. In the present study, the developed and coupled LES-DWOSMC method is capable of solving the aerosol dynamics in turbulent flows.

Abstract

Purpose

The purpose of this paper is to evaluate the effect of adult children migration on the health status of elderly parents. Increased labor migration in developing countries that lack adequate social security systems and institutionalized care for the elderly is a phenomenon that is important to understand. When their adult children go away to work, it is not clear what effect there will be on “left-behind” elderly parents.

Design/methodology/approach

This study employs nearly nationally representative data from five provinces, 25 counties, 101 villages and 2,000 households, collected from two waves of data in 2007 and 2011. This sample comprises a subset of households which include both elderly individuals (above 60 years old) and their grown (working-aged) children in order to estimate the impact of adult child migration on the health of elderly parents in rural China.

Findings

This study finds that adult child migration has a significant positive impact on the health of elderly family members.

Practical implications

These findings are consistent with the explanation that migration raises family resources, which in turn may contribute to better health outcomes for elderly household members.

Originality/value

This is the first paper to attempt to identify the relationship between household migration and the health of elderly parents within the Chinese context.

Abstract

Purpose

The purpose of this paper is to consider the use and application of the “grey system” modelling methodology for the prediction and characterisation of inert anodes used in the aluminium electrolysis industry.

Design/methodology/approach

Cermet was very interesting potential material for developing inert anodes, which was composed of ceramic phase (NiFe2O4) and metal/alloy phase (nickel‐iron‐copper).

Findings

Differential thermal analysis showed that newly fabricated cermet had good performance. The calcination temperature was very important for evaluating material properties, so was obtained in order to build the forecast grey model.

Originality/value

Through calculation the GM(1,1) model was proved to be accurate in predicting technical parameters, and able to pinpoint precisely the properties of cermet materials.

Abstract

Purpose

Managing knowledge effectively and efficiently is considered to be a key success factor to gain sustainable competitive advantage for organizations. This study aims to analyze the impact of knowledge management (KM) processes on human resource management (HRM).

Design/methodology/approach

To test the relationship of KM processes on HRM, a case study was conducted using structural equation modeling based on data collected from employees and managers of a Telecom company in Turkey. The survey instrument is a self-administered questionnaire composed of 37 questions. Three of them are demographic questions; 20 questions aim to reveal KM processes and 14 for HRM practices. The questionnaire was distributed via google survey link to employees and managers in headquarters office and two branches in Istanbul.

Findings

In this paper, the authors tried to investigate the impact of KM practices on the HRM performance of a company. The results indicate that companies with better KM practices tend to perform better at HRM. The main contribution of this paper lies in pointing out that, among the dimensions of KM, knowledge sharing and knowledge utilization have direct impact on HRM, whereas knowledge generation and knowledge sharing have indirect impacts.

Research limitations/implications

The main limitation of this study lies in the fact that data are collected from a single company in telecom industry. Therefore, it is difficult to generalize the results. Although the research findings are aligned with those of the previous studies, further research using data from numerous companies in various industries is still needed to generalize the research findings.

Practical implications

The paper includes implications for the development of knowledge utilization generated and stored within the company. The knowledge can create improvements in the company’s HRM performance if it is shared and used effectively. The paper addresses an important subject and the findings may be used by human resources and KM practitioners interested in the development of organizational knowledge through human resource practices.

Originality/value

This paper fulfills an identified need to investigate the impact of KM practices on the HRM performance of a company.

Abstract

Purpose

The purpose of this paper is to explore whether an in-service life teacher training program can improve boarding students’ health, behavior, and academic performance.

Design/methodology/approach

The authors conducted a cluster-randomized controlled trial to measure the effect of life teacher training on student health, behavior, and academic performance among 839 boarding students in ten central primary boarding schools in Shaanxi. And the authors also tried to identify why or why not life teacher training works. Both descriptive and multivariate analysis are used in this paper.

Findings

The authors find significant improvements in health and behavior. Specifically, compared to boarding students in control schools, 15 percent fewer students in treatment schools reported feeling cold while sleeping at night. The results also showed that student tardiness and misbehaviors after class declined significantly by 18 and 78 percent, respectively. However, the in-service life teacher training program had no measurable impact on boarding students’ BMI-for-age Z-score, number of misbehaviors in class, and academic performance. The analysis suggests that improved communication between life teachers and students might be one mechanism behind these results.

Originality/value

This is the first empirical work which explored how to improve the welfare of boarding students via their life teachers. Because of the sudden increase in boarding students in rural China, it is almost certain that school personnel lack experience in managing boarding students. As such, one promising approach to improving student outcomes might be in-service training for life teachers.

Abstract

Purpose

This paper aims to explain why the quality of infrastructure projects in rural China differs from village to village and how project quality is correlated with project design attributes and governance factors.

Design/methodology/approach

Using primary data collected by the authors on three types of infrastructure projects in villages across China, they created measures of project quality for each village. They then used both descriptive and multivariate approaches to examine how quality varies from village to village and factors correlated with quality.

Findings

Between‐project within‐village quality differences are small and project design has little explanatory power. Between‐village variations are large. There are strong correlations between the ways villages govern themselves and project quality. The authors conclude that it is difficult to make good projects work in communities that lack good governance.

Originality/value

Disaggregated data on the quality of infrastructure (and its determinants) were collected by the authors to allow for variation in the type of infrastructure projects (roads, irrigation, and drinking water) and variation in village governance, making it possible to identify and contrast the effects of project design and village governance factors on project quality. As its chief contribution, this work identifies potential ways to improve the quality of infrastructure projects in rural development.

Abstract

Purpose

This paper aims to provide a systematic framework for organizations to analyze their knowledge reuse processes, and balance codification and personalization within their knowledge strategy according to cost/benefit analysis.

Design/methodology/approach

This paper divides knowledge reuse process into a sequence of five stages, and accordingly analyzes costs/benefits under codification and personalization strategies. Markov decision process, a mathematical framework for multi-stage decision-making, is employed to optimize a mixed strategy for knowledge reuse processes within an organization.

Findings

Organizations need to consider factors such as the number of reusable knowledge items, reuse patterns, and intra-organizational interest alignment which are critical to determine their optimal mix between codification and personalization. Companies should determine a knowledge strategy based on their knowledge reuse contexts instead of following success cases blindly.

Research limitations/implications

This paper presents an illustrative example to show how this framework might be applied by an organization. However, the validity and reliability of strategic decision-making also depends on the accuracy of the model's parameter values. Firms can adopt many methods as surveys, Delphi method, to determine the parameter values.

Practical implications

The proposed framework offers an opportunity for firms to gain insights by setting the model's parameters to their own reuse contexts/characteristics and conducting what-if analysis.

Originality/value

This paper proposes a formal framework for analyzing knowledge reuse processes and offers organizations guidelines about decision-making of knowledge strategies.
