Previous literature has investigated the connection amongst remittances, political stability and unemployment in remittance-receiving economies separately. Besides, they did not cover the Middle East and North African (MENA) region.

To this end, this research uses the pooled mean group (PMG) method.

The findings suggest that the influence of remittances on lowering unemployment accelerates in recipient economies with high levels of political stability.

Policymakers in MENA countries should vigorously pursue political stability, which plays a crucial role in boosting the influence of inward remittances on unemployment alleviation. This is accomplished by establishing solid institutions that contribute to ensuring fair politics, increasing citizens' trust in the government, enhancing the rule of law and protecting investors and prioritizing policies and programs that promote political stability.

This paper, therefore, aspires to empirically examine the impacts of inward remittances on unemployment via the moderating role of political stability in thirteen MENA-receiving countries from 1996 to 2020.

To predict the real behavior of the full-scale model using a scale model, optimized simulation should be achieved. In reinforced concrete (RC) models, scaling can be substantially more critical than in single-material models because of multiple reasons such as insufficient bonding strength between small-diameter steel bars and concrete, and excessive aggregate size. Overall, there is a shortfall of laboratory and field-testing studies on the behavior of secant pile walls under lateral and axial loads. Accordingly, the purpose of this study is to investigate the validity and the performance of the 1/10th scaled RC secant pile wall under the influence of different types of loading.

The structural performance of the examined models was evaluated using two types of tests: bending and axial compression. A self-compacting concrete mix was suggested, which provided the best concrete mix workability and appropriate compressive strength.

Under axial and bending loads, the failure modes were typical. Where the plain and reinforced concrete piles worked in tandem to support the load throughout the loading process, even when they failed. The experimental results were relatively consistent with some empirical equations for calculating the modulus of elasticity and critical buckling load. This confirmed the validity of the proposed model.

According to the analysis and verification of experimental tests, the proposed 1/10th scaled RC secant pile model can be used for future laboratory purposes, especially in the field of geotechnical engineering.

This study used an integrated model that incorporates the Technology Acceptance Model (TAM) and the Theory of Planned Behaviour (TPB) to empirically investigate how eco-gamification stimulates users' sustainability knowledge and, consequently, their pro-sustainable intentions through the mediating roles of sustainable knowledge and psychological and social norms. Thus, the study aims to examine users'’ experiences with the JouleBug app, which is designed to encourage users to complete at least one daily green task.

After a trial period of two weeks, a total of 360 participants completed the post-game survey during the research process.

The findings from the structural equation modeling and data analysis indicated a good fit for the model. The findings demonstrate that usefulness, ease of use and enjoyment of eco-gamification enrich users' sustainability knowledge, which, in turn, strongly influences their pro-sustainable intentions. According to the findings, the three factors of TPB have a significant impact on users' pro-sustainability intentions. Both sustainable knowledge and social cues play mediating roles in such relationships.

This study advocates that eco-gamification can be used as a platform to modify tourists’ pro-sustainability intentions in emerging tourism and technology destinations such as Egypt. Hence, this study offers significant information to tourism planners and other stakeholders on tourists’ behavioural intentions.

This study examined the effectiveness of an integrated model of TAM and TBP in predicting tourists’ intentions to use eco-gamification to improve the sustainability of tourist destinations.

The purpose of this paper is to prepare new disperse dyes and apply for dying polyester fabrics.

The synthetic reaction was carried out through two steps: preparation of arylhydrazones and alkylation using enaminone and dimethylaminovinyl-pyridazine. The high temperature method was used to apply these dyes to polyester fibres.

The study revealed that there is a significant effect of the new prepared disperse dyes on polyester fabrics. The structures of the prepared dyes were established based on elemental analysis and spectral data (infra red (IR), mass spectrometry (MS) and proton nuclear magnetic resonance (¹H-NMR), carbon 13^th nuclear magnetic resonance (¹³C-NMR)).

Disperse dyes containing heterocyclic moiety have attracted great academic and industrial attention owing to their significant. The potential of using disperse dyes easily prepared from arylhydrazones are promise broad applications for these dyes.

The presence of N-thienyl and N-pyridazinyl in the structure of the synthesised disperse dyes would be expected to add the bioactivity advantage. Also, it can be used in formulating the antimicrobial fabrics.

The N-thienyl and N-pyrdiazinyl derivatives of azo dyes are expected to be superior to in the application for fabrics. It may be useful for other applications like painting.

This paper helps to synthesise novel thiophene or pyridazine-based dyestuff for application in dying properties on polyester fabric and study their fastness properties.

The purpose of this paper is to report the findings of a study to explore the Egyptian social science scholars’ academic writing behaviour in local and international context. Understanding the challenges that scholars in social science and humanities face while publishing in the international outlets would help to suggest strategies to improve academic writing in non-Arabic journals.

This study deployed mixed methods approach. The quantitative data were collected using an online questionnaire. Interviews were conducted with a group of scholars in the five faculties to elucidate the publishing behaviour of the sample.

The interviews and the questionnaire showed that social science scholars in Egypt prefer local publishing outlets. The number of scholars who publish internationally is very low compared to scholars who publish locally. Scholars who tried to publish internationally faced many challenges, such as language barriers, lack of academic writing skills and lack of appropriate training.

This study was conducted in one university in Egypt. While the results can be generalised to Egyptian and Middle East universities, it cannot be generalised to non-Arab communities because of the differences in culture and education system.

This study provides insight on publishing practices in the international context among social science scholars in Egypt using a mixed methods approach. This helped to capture the scholarly publishing practices and the attitude toward international publishing and the main challenges that scholars face who attempt to publish in international outlets.

The purpose of this paper is to find out the existing practices of the Islamic banks in providing financing to the customers who have a requirement to purchase a finished property and to examine the existing products used by the Islamic banks in this regard by providing an insight into the modus operandi of these products. In doing this, attempt is made to find out the most famous product offered by the Islamic banks in this regard and to find out whether in reality, Malaysian Islamic banking industry has moved away from Bai Bithaman Ajil (BBA) or not.

This is a qualitative research, largely library-based, and it will consist of secondary sources such as books, journals, articles and other sources related to the Islamic house financing in Malaysia for finished properties. Recent information of the practises of the banks in this regard is obtained from the official websites of the banks.

It is found from this study that majority of Islamic Banks in Malaysia prefer to use the Commodity Murabahah facility for finished property. This finding contradicts with the observations made by some scholars who state that in Malaysia, BBA was initially used, and nowadays, the use of Musharakah Mutanaqisah is more common. The reason why Commodity Murbahah has gained popularity is because of the fact that via the Bursa Suq Al Sila platform, it is easy, swift, reliable, profitable, cheaper, convenient and has zero risk to do this type of transaction at the comfort of the office. It is recommended in this paper to use Musharakah Mutanaqisah, as this contract is an innovative contract that is classified as an equity contract under shariah where risk is shared between the parties. There is need to conduct further research to implement Musharakah Mutanaqisah in Malaysia, specifically to reduce the risk that Islamic Banks will bear by practicing this contract.

The findings of this paper might create confusion among readers, as some may perceive that the finding of the paper is not new as BBA has been dominating Islamic house financing industry from the inception of Islamic banking in the country, and BBA and Murabahah are similar in nature, and as such, commodity Murabahah is also a Murabahah transaction. The reality that needs to be understood is that the way BBA was or is practised in Malaysia in relation to Islamic house financing is that in the name of BBA, the transaction actually followed the Bai’ ‘inah contract, which is a controversial contract among the shariah scholars. Likewise, commodity Murabahah is also a different contract than Murabahah, as it actually refers to tawarruq. As such, this research finding is important to the Islamic banking industry to understand that Malaysia has moved away from the Bai’ ‘inah contract practised in the name of BBA in Islamic house financing, and there are new products introduced by the Islamic banks in Malaysia to replace this practice which were criticised by Shariah scholars.

The rapid spread and severity of the coronavirus (COVID-19) virus have prompted a spate of scholarly research that deals with the pandemic. The purpose of this study is to measure and assess the coverage of COVID-19 research on social media and the engagement of readers with COVID-19 research on social media outlets.

An altmetric analysis was carried out in three phases. The first focused on retrieving all papers related to COVID-19. Phase two of the research aimed to measure the presence of the retrieved papers on social media using altmetric application programming interface (API). The third phase aimed to measure Mendeley readership categories using Mendeley API to extract data of readership from Mendeley for each paper.

The study suggests that while social media platforms do not give accurate measures of the impact as given by citations, they can be used to portray the social impact of the scholarly outputs and indicate the effectiveness of COVID-19 research. The results confirm a positive correlation between the number of citations to articles in databases such as Scopus and the number of views on social media sites such as Mendeley and Twitter. The results of the current study indicated that social media could serve as an indicator of the number of citations of scientific articles.

This study’s limitation is that the studied articles’ altmetrics performance was examined using only one of the altmetrics data service providers (altmetrics database). Hence, future research should explore altmetrics on the topic using more than one platform. Another limitation of the current research is that it did not explore the academic social media role in spreading fake information as the scope was limited to scholarly outputs on social media. The practical contribution of the current research is that it informs scholars about the impact of social media platforms on the spread and visibility of COVID-19 research. Also, it can help researchers better understand the importance of published COVID-19 research using social media.

This paper provides insight into the impact of COVID-19 research on social media. The paper helps to provide an understanding of how people engage with health research using altmetrics scores, which can be used as indicators of research performance.

The purpose of this paper is to present an experimental approach to measure and quantify the three‐dimensional geometrical manufacturing errors on a mass production of parts.

A methodology is developed to model and analyse the combined effect of these errors on a machined feature. Deviation of a machined feature due to the combined errors is expressed in terms of the small displacement torsor (SDT) parameters. Given a tolerance on the machined feature, constraints are specified for that feature to establish a relationship between the tolerance zone of the feature and the torsor parameters. These constraints provide boundaries within which the machined feature must lie. This is used for tolerance analysis of the machined feature. An experimental approach is proposed to measure and quantify the three‐dimensional manufacturing variations as torsors. The results are used to verify the analytical model.

Results show that it is possible to quantify manufacturing dispersions. The paper proposes a measuring method which can be done during the production. In the context of process planning, these experimental data allow us to perform realistic geometrical simulation of manufacturing. The results of this method are torsor components dispersions. Analysis and synthesis of the geometrical simulation of manufacturing are viable with reliable numerical data in order to predict the defects.

To perform realistic geometrical simulation of manufacturing, an experimental approach to measure and quantify the three‐dimensional geometrical manufacturing errors is proposed which is based on the SDT concept.

Calcium and Zinc lignates were proven to be good antioxidants for rubber composites. The purpose of this paper is to evaluate the copper lignate antioxidant activity along with evaluating its electrical conductivity in rubber composites.

The antioxidant activity of the Cu-LSF complex was compared with that of standard commercial antioxidant additives as a green alternative. The rheological characteristics, thermal aging and mechanical and electrical properties were evaluated for the NBR vulcanizates containing the different antioxidants in the presence or absence of coupling agents.

Results revealed that the Cu-LSF complex (5 phr) can function as a compatibilizing, antioxidant and electrical conductivity agent.

The new copper complex prepared from paper-pulping black liquor of wastes could be used as a green antioxidant and electrical conductivity agent in rubber composites.
