Energy systems are quickly in transition and their complexity has been dramatically increased. Although there are numerous studies and researches about future of energy in terms of technology or fuels, few studies have been done based on comprehensive socio-technical dimensions of energy systems’ futures. One key question to fill this gap is that how can we consider electricity as a sustainable common good/resource, beyond some conventional considerations related to public or private sector orientation? The purpose of this study is to find an acceptable answer for this question..

To achieve the purpose of this study, after reviewing some relevant studies, key effective factors on the future of energy have been recognized in an expert panel and structurally analyzed by Micmac software based on cross-impact analyze method. Thereafter, four scenarios for transforming the electricity distribution from a monopoly good to a common resource have been developed and described based on scenario workshops method..

Four scenarios for transforming the electricity distribution from a monopoly good to a common resource have been developed and described. These scenarios include “spider grid,” “local grid,” “intermediate grid” and “off-grid.” Furthermore, different dimensions of electricity as a common good/resource have been investigated. As a result, the authors find out that common resource is a creatable concept that can be referred to some goods depending on certain conditions.

Electricity, like any other resource with common characteristics, can be considered and treated as a common resource, depending on the way we generate, share and distribute it, ownership and property rights, management and decision-making mechanisms, social participation processes and governance criteria.

The purpose of this study is to summarize the available pool of literature on service quality to identify different dimensions of service quality in the healthcare industry and understand how it is measured. The study attempts to explore the research gaps in the literature about different service quality dimensions and patient satisfaction.

A systematic literature review process was followed to achieve the objectives of the study. Various inclusion and exclusion criteria were used to select relevant research articles from 2000–2020 for the study, and a total of 100 research articles were selected.

The study identified 41 different dimensions of healthcare service quality measurement and classified these dimensions into four categories, namely servicescape, personnel, hospital administration and patients. It can be concluded that SERVQUAL is the most widely used service quality measurement tool.

The study identified that a majority of the researchers deduced a positive relationship between SERVQUAL dimensions and the quality of healthcare services. The findings of study will assist hospital executives in formulating effective strategies to ensure that patients receive superior quality healthcare services.

This study aims to explore the evolution of the Islamic capital market (ICM) from the perspective of research publications.

A bibliometric analysis was applied based on selected publications from the Web of Science Core Collection (WoSCC) database from 2000 to 2021. The study adopted VOSviewer software which was developed by Leiden University.

This study has some implications that need urgent action. Firstly, there are some areas that have received little attention among researchers, although they are relevant to the industry, for instance, in fintech and blockchain in ICM. Secondly, the inconsistent frequency of publications in some niche areas may suggest that there are unprecedented events that hinder further research; probably, the researcher may anticipate more information and progress in the industry. Thirdly, the need to strengthen the collaboration between industry and academia to advance research.

This study considered only the WoSCC database. The provider of WoSCC is Clarivate (formerly known as Thomson Reuters), where access to publications is limited to institutional subscribers. The implications of this study are to identify and propose future research trends in the field of ICM.

To the best of the authors’ knowledge, the present study is among the pioneer studies in analysing bibliometric focusing on ICM. Previous research has focused on Islamic finance and banking, and not specifically on ICM. Accordingly, this study sheds light on research gaps in ICM.

The purpose of this study is to understand and analyze the key topics on which scholars have engaged in relation to crowdfunding and its starring role in the Gulf Cooperation Council (GCC) countries from an Islamic perspective. A Structured Literature Review (SLR) is used in this study to assess how scholars carried out their studies in order to better understand future research directions.

The study adopted a SLR methodology and considered 89 peer-reviewed studies published between 1981 and 2021 in GCC countries.

The study identified the starring role of crowdfunding from the Islamic perspective, its role in economic development and its role as a source of finance for new business startups in GCC countries.

Because the research was conducted by a single person, his subjective interpretation might have an impact on the results. Furthermore, only journal papers limited to GCC and published between 1981 and 2021 were examined.

Countries in GCC might recognize the starring role of crowdfunding for their SMEs and economic development.

The authors draw avenues for future research by considering the starring role of crowdfunding using SLR from the Islamic perspective. This helps future researchers to identify the starring role of crowdfunding to contextualize in GCC countries.

This paper aims to investigate the three-dimensional (3D) numerical simulations, based on the Navier–Stokes equations and the energy equation. Forced convection of a mixture of (60:40) percent ethylene glycol and water, was used as the base fluid and CuO nanoparticles, through a serpentine minichannel.

In this simulation, a serpentine mini-channel heat exchanger was simulated. The fluid studied in this simulation was composed of a mixture of (60:40) per cent ethylene glycol and water, was used as the base fluid and CuO nanoparticles. Four slabs and three serpentines were used in this study. The serpentine section is connected to the slab. Three equidistant circular channels (1 mm in diameter) were implemented inside the slab.

Results show that nanoparticles increase the fluid pressure drop and by changing volume fraction of nanoparticles from 0 to 1 per cent, the pressure drop of nanofluids increases between 42and 47 per cent, for Reynolds numbers from 100 to 500. The existence of serpentine bend in the minichannel heat exchanger causes the heat transfer rate to increase. Increase the volume fraction of nanoparticles reduces the fluid temperature at the outlet of the heat exchanger. The numerical results show that in Re = 500, at the beginning of the last slab in middle channel by changing volume fraction of nanoparticles from 0 to 2 per cent, local Nusselt number 57.40 per cent increase. The existence of the serpentine bend causes the heat transfer rate to increase.

Tobacco is the most widely used substance in the world that has been linked to several psychological problems. Few studies have assessed the relationship between dual (waterpipe and cigarette) tobacco smoking. This study aims to examine the relationship between dual tobacco use and symptoms of depression amongst its users.

A cross-sectional study using a random sample of school students was conducted to assess youth tobacco smoking in the central region of Jordan. A self-reported questionnaire including biographical information, smoking status and experience of depression symptoms was used with a sample of 9th to 12th-grade students. χ² and regression test were used to analyze the data.

The final sample comprised 576 school students, of whom 60% were males. The age range was between 16 and 18 years (mean = 15.84 years, SD ± 0.97). 30% of the participants were dual tobacco smokers. A significant difference was found between males and females, with males being more likely to be dual tobacco smokers compared to females. Two depressive symptoms (“feeling sad” and “having crying spells”) had a significant likelihood amongst the youth who were dual smokers.

To the best of the authors' knowledge, this is the first study that aims to report the relationship between dual tobacco smoking and depressive symptoms. Prevention programs are crucial for raising awareness of the harmful effects of dual tobacco smoking and smoking cessation amongst the youth
