Abstract
Purpose
The purpose of this paper is to illustrate the application of statistical tools and techniques for quantitative assessment of spiritual capital (SC) based on a questionnaire survey in the organizations which undergo large-scale organizational change projects.
Design/methodology/approach
A sample of 65 individuals from three organizations were interviewed. The paper uses the 12 principles of transformation available to spiritual intelligence (referred to as SQ characteristics) to assess SC in a two-phase integrated algorithm of principal component analysis (PCA) and fuzzy clustering.
Findings
The paper proposes a two-phase integrated algorithm. In the first phase, PCA is used to reduce the scores of items related to each of SQ characteristics and aggregate them into a single and unique measure. In the second phase, PCA is applied for total SQ quantification. For verification and validation, fuzzy clustering is employed along with PCA to cluster the people in the survey into different classes, which may possess different stocks of SC and rank them based on their level of SQ. The results of PCA are verified and validated by fuzzy clustering revealing the applicability and usefulness of PCA for SC quantification.
Research limitations/implications
The paper is based on individual judgments about their own SQ characteristics hence the results of questionnaire survey may be biased by individual personal characteristics. Future research can apply the proposed algorithm and check for its reliability using other psychometric instruments available in the field.
Originality/value
The paper contributes by filling a gap in the quantitative management tools literature, in which empirical studies on validated multivariate analysis of spirituality have been scarce until now.

Abstract
Purpose
The purpose of this paper is to provide an overview of the research in a project aimed at developing manufacturing techniques for integrated optical and electronic interconnect printed circuit boards (OPCB) including the motivation for this research, the progress, the achievements and the interactions between the partners.
Design/methodology/approach
Several polymer waveguide fabrication methods were developed including direct laser write, laser ablation and inkjet printing. Polymer formulations were developed to suit the fabrication methods. Computer‐aided design (CAD) tools were developed and waveguide layout design rules were established. The CAD tools were used to lay out a complex backplane interconnect pattern to meet practical demanding specifications for use in a system demonstrator.
Findings
Novel polymer formulations for polyacrylate enable faster writing times for laser direct write fabrication. Control of the fabrication parameters enables inkjet printing of polysiloxane waveguides. Several different laser systems can be used to form waveguide structures by ablation. Establishment of waveguide layout design rules from experimental measurements and modelling enables successful first time layout of complex interconnection patterns.
Research limitations/implications
The complexity and length of the waveguides in a complex backplane interconnect, beyond that achieved in this paper, is limited by the bend loss and by the propagation loss partially caused by waveguide sidewall roughness, so further research in these areas would be beneficial to give a wider range of applicability.
Originality/value
The paper gives an overview of advances in polymer formulation, fabrication methods and CAD tools, for manufacturing of complex hybrid‐integrated OPCBs.

Abstract
Purpose
In the current dynamic environment, technological capabilities and open innovation play vital roles in operational performance of small and medium enterprises (SMEs). Thus, the purpose of this paper is to explore the influence of technological capabilities on open innovation and consequent impact on perceived operational performance of the SMEs in Malaysia by considering the moderating effect of environmental dynamism.
Design/methodology/approach
This study is quantitative in nature and used a survey questionnaire to gather responses from 202 SME owners in Malaysia. The data were analyzed with SmartPLS software, as it used structural equation modeling.
Findings
The results show that technological capabilities significantly influence open innovation whereas open innovation plays an instrumental role to achieve operational performance of the SMEs. Interestingly, environmental dynamism was found to have a negative moderating role in the relationship between open innovation and perceived operational performance.
Practical implications
This paper will assist SME managers in making effective decisions while using technological capabilities and open innovation practices. Managers need to be aware of the vital role of technological capabilities to build external and internal collaboration and incorporate their knowledge that is necessary for open innovation practices. The results also assist managers in a way that in the dynamic and competitive environment SMEs should take further proactive actions to compete in the market to survive.
Originality/value
This study provides new insights by dismantling technological capabilities and open innovation to understand further the effects of technological capabilities on open innovation and its consequence on a firm’s operational performance.

Abstract
Purpose
This research aimed to visualize and analyze the co-word network and thematic clusters of the intellectual structure in the field of linked data during 1900–2021.
Design/methodology/approach
This applied research employed a descriptive and analytical method, scientometric indicators, co-word techniques, and social network analysis. VOSviewer, SPSS, Python programming, and UCINet software were used for data analysis and network structure visualization.
Findings
The top ranks of the Web of Science (WOS) subject categorization belonged to various fields of computer science. Besides, the USA was the most prolific country. The keyword ontology had the highest frequency of co-occurrence. Ontology and semantic were the most frequent co-word pairs. In terms of the network structure, nine major topic clusters were identified based on co-occurrence, and 29 thematic clusters were identified based on hierarchical clustering. Comparisons between the two clustering techniques indicated that three clusters, namely semantic bioinformatics, knowledge representation, and semantic tools were in common. The most mature and mainstream thematic clusters were natural language processing techniques to boost modeling and visualization, context-aware knowledge discovery, probabilistic latent semantic analysis (PLSA), semantic tools, latent semantic indexing, web ontology language (OWL) syntax, and ontology-based deep learning.
Originality/value
This study adopted various techniques such as co-word analysis, social network analysis network structure visualization, and hierarchical clustering to represent a suitable, visual, methodical, and comprehensive perspective into linked data.

Abstract
Purpose
Cryptocurrencies, which have been popular since 2009, raise concerns among investors, researchers and professionals. Amid global economic, financial and health crises, uncertainty has surged, leading investors to seek risk reduction and portfolio diversification. While some critique conventional fiat-based cryptocurrencies, others propose asset-backed alternatives. However, the impact of Shari’ah law-based cryptocurrencies on equity market returns remains largely unexplored in existing literature. This study aims to investigate the lead/lag relationship of selected Islamic and conventional cryptocurrencies from ASEAN and global perspectives.
Design/methodology/approach
The authors collected daily data of Bitcoin, Ethereum, X8X (Islamic cryptocurrency), Cardano (Islamic cryptocurrency), S&P500, Volatility Index, Economic Policy uncertainty and FTSE Asean Index (from the 4th of November 2019 to the 1st of July 2022) to reveal empirical results through Continuous Wavelet Transform and Correlation Heatmap with Dendrogram.
Findings
The findings indicate that Bitcoin offers a diversification opportunity for FTSE ASEAN investors for the long-term horizon while S&P500 investors will benefit from short-term investment. On the other hand, Ethereum provides better investment opportunities for both indices in the short run compared to long run. Cardano and X8X offer better investment opportunities in the long run for S&P500 and FTSE ASEAN investors. Interestingly, to check the robustness, the authors used correlation Heatmap based on Dendrogram which provided almost similar results.
Originality/value
This study contributes fresh insights to the existing literature concerning cryptocurrency due to the inconclusive findings of past studies, investors are curious to know the impact of cryptocurrency on stock market return from a global perspective which is extensively overlooked, and whether there is any difference between Islamic and conventional cryptocurrency. Therefore, by investigating the abovementioned timely demand issue, this study substantially contributes to the body of cryptocurrency literature.

Abstract
Purpose
The purpose of this study is to empirically examine the direct effect of extra-industry network (EIN) and organization–stakeholder relationships (OSR) on absorptive capacity (ACAP). In addition, this study explored indirect effects of EIN and OSR on performance through ACAP among small- and medium-sized enterprises (SMEs) in Oman by considering the moderating role of big data analytics (BDA) outsourcing.
Design/methodology/approach
This study utilized quantitative method through survey questionnaire. The hypotheses were tested with a sample size of 202 surveys completed by SME owners. Partial least squares-structural equation modeling (PLS-SEM) was administered to analyze data via the SmartPLS 4.0 software.
Findings
The analysis revealed that EIN and OSR had an indirect effect on performance through ACAP, while propensity to outsource BDA was found to have a positive moderating role between EIN and performance. Interestingly, propensity to outsource BDA was found to have a negative moderating influence on the relationship between ACAP and performance.
Practical implications
This research is beneficial for entrepreneurs who wish to learn about the specific intangible resources significant for venture growth, to devise effective strategies to expand their EIN and OSR and to consider the significance of the correlations established in this study through ACAP. The result also assists managers in a way that the propensity to outsource BDA strengthens the positive effect of EIN on performance and weakens the positive effect of ACAP on performance.
Originality/value
This research appears to be among the first empirical studies that attempt to provide insights into the importance of ACAP as the key mechanisms to transform the advantages of EIN and OSR to enhance performance by considering the moderating role of propensity to outsource BDA.

Abstract
Purpose
The study aims to test the framework that proposes the role of resources (intellectual capital) in mobilizing entrepreneurial orientation that influences the competitiveness improvement of micro-small-medium enterprises (MSMEs) under the lens of resource orchestration theory.
Design/methodology/approach
In this study, 347 respondents from the MSMEs participated through a structured questionnaire. For the data analysis purpose, the structural equation modeling technique was employed using SmartPLS software.
Findings
The results suggest human, structural, and relational capital are significant antecedents of entrepreneurial orientation, which leads to competitiveness improvement. The findings also indicate the mediation role of entrepreneurial orientation between intellectual capital and competitiveness improvement.
Practical implications
The current study presumably will supplement the promising research effort to progress the research orchestration theory and also could be a strategic guideline for the managers/owners of the MSMEs.
Originality/value
This study is possibly a novel attempt to divulge the association between intellectual capital (tripartite model) and competitiveness improvement of firms under the lens of resource orchestration theory.

Abstract
Purpose
The increasing prevalence of coronavirus disease (COVID-19) is a global crisis that leads to physical and psychological outcomes for health-care workers, so this study aims to investigate the mental health outcomes (including general health, generalized anxiety disorder and posttraumatic stress disorder) in health-care workers in Rafsanjan, Iran.
Design/methodology/approach
By using convenience sampling, this cross-sectional study was conducted on 332 health-care workers working in public hospitals in southern Iran. Data collection lasted from March to April 2020. General Health Questionnaire (GHQ-28), Generalized Anxiety Disorder 7-item (GAD-7) and Impact of Event Scale were used to collect data. The data were then analyzed by using SPSS 25 and descriptive and inferential statistics (chi-square and multivariate logistic regression).
Findings
In total 45.5% of the participants had psychological disorder according to GHQ. In addition, 25.3% of the participants had GAD and 31.6% had posttraumatic stress disorder (PTSD). The results using multivariate logistic regression showed that only income was significantly associated with psychological disorders (95% confidence interval for odds ratio: 1.32–6.45, P = 0.008).
Practical implications
According to the results, the incidence of GAD and PTSD was high among health-care workers. Therefore, it is recommended that the psychological skills of health-care workers be strengthened through counseling and training programs.
Originality/value
This paper provides a novel analysis of mental health in health-care workers in Iran.

Abstract
Purpose
The purpose of this study is to examine the impact of knowledge management dimensions (i.e. knowledge acquisition, knowledge dissemination and knowledge responsiveness) on green innovation. The study also seeks to determine whether these relationships are mediated by the environmental awareness in small and medium enterprises (SMEs) in the UAE.
Design/methodology/approach
Data were obtained from a sample of 194 SMEs (two informants from each firm that consist of 388 top managers) in Abu Dhabi, UAE. In this cross-sectional study, convenience random sampling was used. The positivism approach was adopted using a hypothetical statistical induction method. Validated measurement scales were used to measure the study constructs adopted from previous studies. Data were analysed using a quantitative approach with Smart partial least squares structural equation modelling (PLS-SEM) 3.0.
Findings
The results of the study indicated a positive and significant association between knowledge acquisition, knowledge dissemination and knowledge responsiveness with green innovation. Moreover, the data analysis confirmed that environmental awareness mediates the relationship between knowledge dissemination and green innovation. However, no mediation role of environmental awareness in the relationship between knowledge acquisition and knowledge responsiveness with green innovation was found.
Practical implications
Knowing how to manage knowledge effectively is considered to be one of the most important aspects of green innovations. Nonetheless, there was a dearth of literature highlighting the relevance of knowledge management for long-term organisational success. The results of this study present practical implications for SME professionals. Green innovation with the support of environmental awareness may help a firm understand and implement the importance of knowledge management into their administrative operations. They can subsequently become eco-innovative ecologically, economically and socially.
Originality/value
This is one of the very few studies that examine the effect of knowledge management dimensions (knowledge acquisition, knowledge dissemination and knowledge responsiveness) on green innovation in UAE SMEs.

Abstract
Purpose
The purpose of this research was to model the impact of customer knowledge on the performance of organization with a focus on information technology industry. Furthermore, it is intended to analyze the effect of customer knowledge investment on the performance measures, by reviewing investment policies.
Design/methodology/approach
The relationship between customer knowledge and performance measures was specified using literature review and grounded theory method. The system dynamics approach was then applied to analyze the impact of the customer knowledge on the performance measures.
Findings
This study provided a dynamic model on the causal relationship between customer knowledge and organizational performance. The results showed that measures such as product development, financial performance, idea generation, technical knowledge and knowledge maturity were affected by the customer knowledge while the relationship with customer loyalty and the number of customers was not proven. Besides, it was found that to increase the impact of customer knowledge on organizational performance, knowledge maturity was essential, and investing on customer knowledge without investing on knowledge maturity would reduce the organizational performance. The results also showed that more knowledge investment would not necessarily increase financial strength of the organization.
Practical implications
Results of this study could be useful for strategy formulation and deployment especially for IT-based companies showing the importance of investment on customer knowledge on the one hand and the knowledge maturity in the organization on the other hand.
Originality/value
In this research, the impact of customer knowledge on both financial and nonfinancial performance measures was studied showing new findings on the dynamism of their relationships.
