Rheumatoid arthritis is a common chronic disease associated with significant morbidity and mortality. As with all chronic conditions, active participation by the patient, in areas ranging from accepting the diagnosis and its treatment to the implementation of coping strategies, is essential for effective management. Involving any patients in these process can be difficult; however patients of South Asian origin can present particular challenges. Many patients of South Asian origin have beliefs about disease causation and the utility of pharmacological and non‐pharmacological treatments that differ from those held by other patients. Communication difficulties can make it difficult for health care professionals to address these issues. We discuss strategies to support patients and encourage their involvement including linguistically appropriate educational material, peer support and telephone helplines.

This paper aims to examine the relationship between trade and economic growth using data of UAE economy for the period of 1974-2011.

The bounds testing is applied for testing the cointegration relationship between the variables. The rolling window approach has been used to analyze the stability of long run coefficients.

The empirical analysis shows the presence of cointegration between trade and economic growth. Furthermore, exports have positive, but imports have negative effect on economic growth. The rolling window approach confirms the stability of long-run estimates.

This paper provides new insights for policymakers to use trade as economic tool for sustainable economic development.

This paper makes a unique contribution to the literature with reference to UAE, being a pioneering attempt to investigate the relationship between trade and economic growth by using long time series data and applying more rigorous techniques like time varying rolling window analysis.

In this study, the authors analyze the impact of geopolitics risk on Sukuk, Islamic and composite stocks, oil and gold markets and portfolio diversification implications during the COVID-19 pandemic and Russia–Ukraine conflict period.

The study used a mix of wavelet-based approaches, including continuous wavelet transformation and discrete wavelet transformation. The analysis used data from the Geopolitical Risk index (GP{R), Dow Jones Sukuk index (SUKUK), Dow Jones Islamic index (DJII), Dow Jones composite index (DJCI), one of the top crude oil benchmarks which is based on the Europe (BRENT) (oil fields in the North Sea between the Shetland Island and Norway), and Global Gold Price Index (gold) from May 31, 2012, to June 13, 2022.

The results of the study indicate that during the COVID-19 and Russia–Ukraine conflict period geopolitical risk (GPR) was in the leading position, where BRENT confirmed the lagging relationship. On the other hand, during the COVID-19 pandemic period, SUKUK, DJII and DJCI are in the leading position, where GPR confirms the lagging position.

The present study is unique in three respects. First, the authors revisit the influence of GPR on global asset markets such as Islamic stocks, Islamic bonds, conventional stocks, oil and gold. Second, the authors use the wavelet power spectrum and coherence analysis to determine the level of reliance based on time and frequency features. Third, the authors conduct an empirical study that includes recent endogenous shocks generated by health crises such as the COVID-19 epidemic, as well as shocks caused by the geopolitical danger of a war between Russia and Ukraine.

1. We analyze the impact of geopolitics risk on Sukuk, Islamic and composite stocks, oil and gold markets and portfolio diversification implications during the COVID-19 pandemic and Russia–Ukraine conflict period.

2. The results of the wavelet-based approach show that Dow Jones composite and Islamic indexes have observed the highest mean return during the study period.

3. GPR and BRENT are estimated to have the highest amount of risk throughout the observation period.

4. Dow Jones Sukuk, Islamic and composite stock show similar trend of volatility during the COVID-19 pandemic period and comparatively gold observes lower variance during the COVID-19 pandemic and Russia–Ukraine conflict.

This study aims to examine the hedge and safe-haven properties of the Sukuk and green bond for the stock markets pre- and during the COVID-19 pandemic period.

To test the hedge and safe-haven characteristics of Sukuk and green bonds for stock markets, the study first uses the methodology proposed by Ratner and Chiu (2013). Next, the authors estimate the hedge ratios and hedge effectiveness of using Sukuk and green bonds in a portfolio with stock markets.

Strong safe-haven features of ethical (green) bonds reveal that adding green bonds into the investment portfolios brings considerable diversification avenues for the investors who tend to take fewer risks in periods of economic stress and turbulence. The hedge ratio and hedge effectiveness estimates reveal that green bonds provide sufficient evidence of the hedge effectiveness for various international stocks.

The study has significant implications for faith-based investors, ethical investors, policymakers and regulatory bodies. Religious investors can invest in Sukuk to relish low-risk and interest-free investments, whereas green investors can satisfy their socially responsible motives by investing in these investment streams. Policymakers can direct the businesses to include these diversifiers for portfolio and risk management.

The study provides novel insights in the testing hedge and safe-haven attributes of green bonds and Sukuk while using unique methodologies to identify multiple low-risk investors for investors following the uncertain COVID-19 pandemic.

This study aims to investigate the influence of systemic banking crises, currency crises and global financial crisis on the relationship between export and economic growth in China by using the annual time series data from the period of 1972 to 2014.

The Johansen and Jeuuselius’ cointegration, auto regressive distributed lag bound testing cointegration, Gregory and Hansen’s cointegration and pooled ordinary least square techniques with error correction model have been used.

Results indicate the positive and significant effect of export of goods and services on economic growth in both long and short run, whereas the negative influence of systemic banking crises and currency crises over economic growth is observed. It is also concluded that the impact of export of goods and service on economic growth becomes insignificant in the presence of systemic banking crises and currency crises. The currency crises effect the influence of export on economic growth to a higher extent compared to systemic banking crises. Surprisingly, the export in the period of global financial crises has a positive and significant influence over economic growth in China, which conclude that the global financial crises did not drastically affect the export-growth nexus.

This paper makes a unique contribution to the literature with reference to China, being a pioneering attempt to investigate the effects of systemic banking crises and currency crises on the relationship of export and economic growth by using long-time series data and applying more rigorous econometric techniques.

Growing attention of policymakers, governments and regulation authorities towards climate change and global warming has spurred the extensive need to carefully examine the current practices of green and sustainable finance. This study aims to provide a comprehensive analysis on the current state and future directions of green and sustainable finance through bibliometric analysis.

For extensive bibliometric analysis, the study comprises 1,413 documents published in peer-reviewed journals indexed in the SCOPUS database for the period ranging from 1990 to 2021.

The authors find that there are mainly three key areas of green and sustainable finance, which are largely addressed by the scholars following the given time. The key areas include socially responsible investments, green finance and climate finance that are in line with the previous studies and existing trends and practices prevailing in the business and corporate world.

The findings are important for policymakers, regulatory bodies, upcoming scholars, environmentalists and investors as findings of the study provide an effective framework for adopting sustainable strategies, to trade-off between profits and environmental hazards and to generate value from the green avenues of research and practice.

The study offers novel contributions to the existing literature in terms of comprehensively providing evidence of the current practices of green and sustainable finance. Meanwhile, significant implications for the prospective audience further refine the contribution of research.

This study aims to examine the hedge, diversifier and safe-haven properties of bonds against infectious disease-related equity market volatility (IDEMV), like COVID-19.

The authors apply wavelet coherence methodology on the daily data of IDEMV and bond market (US, UK, Japan, Switzerland, Canada, Australia, Sweden, China and Europe) indices from 1 January 2000 to 14 February 2021.

The results show no significant co-movement between these bond indices and IDEMV, thus confirming that they serve as a hedge against IDEMV. However, during the turbulent period like COVID-19, the authors find that the US, UK, Japan, Switzerland, Canada, Australia, Sweden, China and European bond markets act as safe-haven against IDEMV, whereas the UK, US, Japan and Canadian bond markets demonstrate an in-phase and positive co-movement with IDEMV during COVID-19, suggesting their role as a diversifier.

The study findings are important for investors and portfolio managers regarding risk management, portfolio diversification and investment strategies.

The authors contribute to the fast growing body of work on the financial impacts of COVID-19 as well as to ongoing consideration of whether a bond is a safe-haven investment.

The purpose of this paper is to explore the effect of affiliative-based humorous leadership on hotel employee outcomes (i.e. resistance to change and upward voice), underpinned by affective events theory. Further, this paper investigates psychological capital as a mediation effect and emotional intelligence as a moderation effect.

Using a structured questionnaire, 554 supervisors of 20 four- and five-star hotels in Sharm El-Sheikh responded based on a time-lagged approach. A Smart-partial least squares (Smart-PLS) v. 3.3.9 was used to analyze the data set.

The findings revealed that affiliative-based humorous leadership has a positive effect on psychological capital, and psychological capital has a positive association with employee upward voice. Psychological capital partially mediated the linkage of humorous leadership with employees' upward voices and resistance to change. According to the results, emotional intelligence strengthened the linkage of psychological capital with employee resistance to change and upward voice.

The findings contribute to the body of knowledge on humor and the development of new ideas in the hospitality literature. This paper adds to the hospitality literature on humorous leadership in developing countries, specifically in Egypt. This paper also provides practitioners with new perspectives as they develop strategies and use humor-related wise leadership styles in the workplace.

To the best of the authors’ knowledge, this paper is one of the first studies to assess affiliative-based humor in leadership in the hospitality industry. This paper contributes to future studies on the crucial effect of workplace engagement and its association with employees’ novel and intriguing actions and offers a good guideline for organizations and enterprises wishing to better leverage leader humor.

The purpose of this study is to investigate the impact of foreign capital inflows and economic growth on stock market capitalization in Pakistan by using the annual time series data from the period of 1976 to 2011.

The autoregressive distributed lag bound testing cointegration approach, the error correction model and the rolling window estimation procedures have been performed to analyze the long run, short run and behavior of coefficients, respectively.

Results indicate that foreign direct investment (FDI), workers’ remittances and economic growth have significant positive relationship with the stock market capitalization in long run as well as in short run. Results of the dynamic ordinary least square and the fully modified ordinary least square suggest that the initial results of long-run coefficients are robust. Results of variance decomposition test show the bidirectional causal relationship of FDI and economic growth with stock market capitalization. However, unidirectional causal relationship is found in between workers’ remittances and stock market capitalization.

It is suggested that in Pakistan, investors can make their investment decisions through keeping an eye on the direction of the considered foreign capital inflows and economic growth.

This paper makes a unique contribution to the literature with reference to Pakistan, being a pioneering attempt to investigate the effects of foreign capital inflows and economic growth on stock market by using long time series data and applying more rigorous techniques.

This study aims to seek to understand counterproductive knowledge behaviour (CKB) in higher education institutions (HEIs) by integrating knowledge hiding (KHi) and lack of knowledge sharing (LKS).

The current research uses a hybrid conceptual review combining the bibliometric study and conceptual review of 47 articles. The bibliometric analysis aimed to identify research maps, and the conceptual review sought to understand the current development of research fields.

The bibliometric analysis highlights essential summaries, such as the pioneering authors, seminal papers and conceptual maps. However, knowledge hoarding as a dimension of LKS appears in the niche theme. The conceptual analysis indicates three groups of factors contributing to KHi and LKS. Moreover, the study highlights the causal relation between both KHi as well as LKS and faculty member performance while proposing remedies derived from integrating the social exchange theory (SET) and conservation of resource (COR) theory.

The present study provides an integrated image of KHi and LKS in the HEI context, as well as its potential remedies by integrating SET and COR. The basis of this study is a literature review; thus, future studies are recommended to empirically explore the integration of KHi and LKS within the HEI context.

This research provides an overview for HEI policymakers to re-examine the critical role of institutional research as one of the considerations for evaluating and developing policies. Specifically, policymakers can reflect on all policy directions to determine whether there are any symptoms of CKB in the institutions. Moreover, stakeholders can find out the reason behind the non-optimal performance of faculty members regarding CKB and any mitigating factors.

Understanding CKB is crucial in managing HEI. This research provides a comprehensive image of KHi and LKS within HEI, especially in a collectivist culture.
