With reference to the methodology of Prof Choudhry in his book “Tawhidi Epistemology and its Applications: Economics, Finance, Science, and Society” in 2014, in a different context, this study aims to present the conceptual fundamental of Islamic finance investment, where investment decisions are governed by Divine law and Islamic jurisprudence, followed by the empirical nature of real-world issues where investment decisions are governed by only financial indicators, using the Amman Stock Exchange as a case study.

As pointed out by Raderbauer (2011), research and industry initiatives mainly focus on environmental measures while ignoring the economic and socio-cultural dimension of sustainability. Recognizing the importance of a holistic understanding to define sustainable business practices for the accommodation industry. Financial markets are no exception; moral and values either coming from secular or religious understanding help to examine relationships between attitudes and actions, as well as differences in attitudes and actions related to the business’ characteristics. In business, ethical considerations apply to a broad list of virtues that companies, their managers and employees customarily seek to adopt. These include, but are not limited to, the encouragement of honesty, integrity and efficiency, as well as diversity and communication skills. One of the most common sources of ethical considerations is religion. In these cases, religious doctrine imparts a sense of applied ethics, where one considers what right conduct is, how to live a life pleasing to the Divine and how one should treat him/herself and others in accordance with those teachings. Again, as ethical considerations is a broad philosophical concept, it can apply to any situation where the person ponders the nature of right and wrong, how to recognize the difference and the meaning those conclusions carry for everyday life.

It can be concluded that the overall the quantitative and qualitative statistics showed that accommodation business manager’s decision has had a very little positive attitude toward sustainability and the implementation of sustainable business practices in ASE financial transaction, no matter what classification, type of business, ownership or size of business. Only rules and regulations govern the attitude and behavior when making financial transactions with profit is the main target. Moral indicators could not be seen throughout the analysis and test used to achieve objectives of the study at hand. One can imagine that the combined two factors together “Moral-Material” in implementing financial transactions will produce a more beneficial outcome. Achieving a material and holistic objective will produce an optimum situation, which can contribute positively to sustainable development.

Islamic alternatives to traditional investment tools have been driven by the fact that such tools do not conform to the Islamic general principles of the Shari’ah (Usmani, 2002). There has been a growing desire to have funds in which profits are not based on riba or interest, which is prohibited in Islam. Muslims deem that profit should come because of efforts; this is not the case in interest-dominated investments. In addition, there is a desire to have investment portfolios, which are morally purified. Thus, investments in companies that are not in compliance with the Shari’ah are not permitted and are eliminated from the portfolio. To ensure compliance with the forgoing condition, Shari’ah advisory boards whose role is mainly to give assurance that money is managed within the framework of Islamic laws govern Islamic mutual funds (Hassan, 2001; Hassan, 2002). On the other hand, dealing with the applied part, the paper will deal with a case study from Jordan (Amman Stock Exchange), where, code of ethics is issued by virtue of the provisions of Article 26 (e) of the Securities Law No. 23 of 1997. The Amman Stock Exchange operates as an exchange for the trading of securities. The company lists securities such as equities and bonds. Its activities include providing enterprises with a means of raising capital by listing on the exchange; encouraging an active market in listed securities based on the determination of prices and trading; providing facilities and equipment for trading the recoding of trades and publication of prices; monitoring and regulating market trading; and coordinating with the Jordan Securities Commission as necessary. The company’s activities also include ensuring compliance with the law, fair market and investor protection; setting out and enforcing a professional code of ethics.

The purpose of this study is to describe the efforts undertaken to convert the large university campus of Jordan University of Science and Technology (JUST) into a green, resource-efficient and low-carbon campus by following an action-oriented strategy. Sustainability features of the campus were discussed and benchmarked. Challenges were identified and remedial actions were proposed.

Taking 2015 as the baseline year, data on energy, water consumption and solid waste generation for the university campus were collected. Energy consumption for cooling, heating and transportation, besides electric power consumption, were reported, and the associated carbon dioxide (CO₂) emissions were estimated. By calculating the full time equivalent of students and employees, carbon emission and water consumption per capita were calculated. A comparison with other universities worldwide was conducted.

Although located in a semiarid region with scarce water resources, JUST has set an example by greening its campus through an action-oriented approach. It was found that the per capita carbon emission for JUST campus was 1.33 ton of CO₂ equivalent, which is less than the emissions from campuses of other universities worldwide. As for water, this study revealed that the daily per capita water consumption was about 56 L, which is approximately one-third of that for students in institutions in the USA. Furthermore, the findings of this study indicated that the average solid waste generation rate was 0.37 kg per student per day compared to 0.31 kg per capita per day when considering the university community (students and employees) collectively. These figures were less and thus compare favorably to the corresponding data for other universities in both developing and developed countries.

This research addresses the issue of greening JUST campus, which is one of the largest university campuses in the world. JUST campus is located in a semiarid, water-scarce country, which on its own poses a serious challenge. The originality and value of this study mainly stem from the facts that on the one hand, this is one of the unique and pioneering comprehensive studies of its type and, on the other hand, other universities with similar conditions can benefit from the findings of this research to meet the sustainability objectives on their campus operations.

The Health Sector Evolution Plan (HSEP) is the most recent reform in Iran’s health care system that was launched in May 2014 in all university-affiliated hospitals to reduce health care expenditure for patients, while improving the efficiency and quality of hospital services. The purpose of this paper is to evaluate the impact of the HSEP on the performance of 15 hospitals affiliated with Kermanshah University of Medical Sciences (KUMS), located in the western region of Iran.

The Pabon Lasso model was used to measure the performance of hospitals before and after the implementation of the HSEP in 2013-2014 and 2015-2016, respectively. Three indicators of average length of stay (ALoS), bed occupancy rate (BOR) and bed turnover rate (BTR) were analyzed by the Pabon Lasso model.

The results showed that the average ALoS, BTR and BOR before the introduction of the HSEP were 2.59 days, 92 times and 57 percent, respectively, and the corresponding figures for these indicators after the implementation of the HSEP were 2.61 days, 98.9 times and 59.9 percent. The results indicated that before the introduction of the HESP, 40 percent of hospitals were in zone 1 (poor performance: low BTR and BOR and high ALoS), 27 percent in zone 2, 20 percent in zone 3 (good performance: high BTR and BOR and low ALoS) and 13 percent in zone 4. After the HSEP, the proportion of hospitals in zones 1-4 was 33, 27, 20 and 20 percent, respectively.

This study is the first to use the Pabon Lasso model technique to evaluate the impact of the HSEP on hospitals affiliated with KUMS.

This study aims to explore the hijab research impactful authors, influential journals, collaboration networks and emerging trends. In addition, keyword co-occurrence techniques are used to scrutinize the field’s major schools of thought.

Hijab research has witnessed a distinct proliferation during the past decade. In this article, the authors apply bibliometric network techniques to examine the conceptual/intellectual structure of this domain based on 485 Web of Science documents written by 848 authors representing 66 nations and spanning almost 40 years (1984–2021).

Results show that the most impactful journals publishing hijab research are Women’s Studies International Forum, Gender, Place and Culture, Ethnic and Racial Studies and the Journal of Islamic Marketing. Results also show that the author collaboration network in hijab research is sparse. Furthermore, results related to collaborative networks between institutions and countries reveal a global “North–South” schism between developed and developing nations. Finally, the multiple correspondence analysis applied to obtain the hijab research conceptual map reflects the depth and breadth of the field’s foci.

The present analysis has far-reaching implications for aspiring researchers interested in hijab research as the authors retrospectively trace the evolution in research output over the past four decades, establish linkages between the authors and articles and reveal trending topics/hotspots within the broad theme of hijab research.

The purpose of this paper is to examine empirically the efficiency types of Islamic and conventional banks. It seeks to show whether the efficiency level of conventional and Islamic banks significantly differs from each other. In addition, it investigates the influential factors on each type of efficiency.

The paper utilises the data envelopment analysis in its windows version to estimate the efficiency scores reflecting the time variance and compares between banking models. The paper uses pure technical efficiency (TE) and scale efficiency to achieve the objective of the study. In addition, the panel data technique is adopted to assess the determinants of the efficiency of the banks econometrically.

The findings of panel regression initially indicate that the pure TE is higher for conventional banks compared to Islamic banks. However, the Islamic banks are more scale efficient than their conventional counterpart. Macro and micro indicators have different impacts on the both types of efficiency. However, the unique factors that show consistent influence on the efficiency types were loans/finance, non-interest income/finance/liquidity and GDP. Furthermore, the determinants are shaped differently for Islamic and conventional banks when the banking model is controlled for.

This paper examines the efficiency types using a unique window analysis approach to examine the types of efficiency with a longitudinal set of data from 1996 to 2011.

The purpose of this paper is to examine the banking industry’s efficiency using the case of Yemen.

The paper utilises two-stage analysis to evaluate the efficiency adopting Data Envelopment Window Analysis (DEWA) in the first stage for the period 1996-2011. Furthermore, the paper addresses, in two-dimensional matrix, the stability and efficiency of the banking sector in order to assess their ability for survival. In the second stage, panel data analysis is applied to regress a set of bank-specific and macro-economic variables on the efficiency of the banking sector in Yemen in a comparative fashion between Islamic and conventional banks.

The findings of the investigation indicate that the Yemeni banking industry in general was on a declining efficiency’s trend with increased instability during the later period of the investigation. In addition, the study shows that most conventional banks were relatively stable, though inefficient, while Islamic banks were more efficient over the time. The results of panel data regression further suggest that efficiency is related to a number of determinants. Loan/financing, and profitability are the common key determinants of efficiency for both Islamic and conventional banks. However, other determinants have impacted differently for Islamic and conventional banks, which could reflect the uniqueness of their operation and structure.

The present study provides a basis for the regulators and bankers to assess the viability of the banking sector and proposes policies to restructure the industry in order to enhance the performance of the whole industry.

The paper presents new empirical findings on the efficiency of Islamic and conventional banks in Yemen.

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.
