The aim of this paper is to investigate the relationship between the ring structure of the twisted partial skew generalized power series ring RG,≤;Θ and the corresponding structure of its zero-divisor graph Γ̅RG,≤;Θ.

The authors first introduce the history and motivation of this paper. Secondly, the authors give a brief exposition of twisted partial skew generalized power series ring, in addition to presenting some properties of such structure, for instance, a-rigid ring, a-compatible ring and (G,a)-McCoy ring. Finally, the study’s main results are stated and proved.

The authors establish the relation between the diameter and girth of the zero-divisor graph of twisted partial skew generalized power series ring RG,≤;Θ and the zero-divisor graph of the ground ring R. The authors also provide counterexamples to demonstrate that some conditions of the results are not redundant. As well the authors indicate that some conditions of recent results can be omitted.

The results of the twisted partial skew generalized power series ring embrace a wide range of results of classical ring theoretic extensions, including Laurent (skew Laurent) polynomial ring, Laurent (skew Laurent) power series ring and group (skew group) ring and of course their partial skew versions.

In this work, the authors are interested in the notion of vector valued and set valued Pettis integrable pramarts. The notion of pramart is more general than that of martingale. Every martingale is a pramart, but the converse is not generally true.

In this work, the authors present several properties and convergence theorems for Pettis integrable pramarts with convex weakly compact values in a separable Banach space.

The existence of the conditional expectation of Pettis integrable mutifunctions indexed by bounded stopping times is provided. The authors prove the almost sure convergence in Mosco and linear topologies of Pettis integrable pramarts with values in (cwk(E)) the family of convex weakly compact subsets of a separable Banach space.

The purpose of the present paper is to present new properties and various new convergence results for convex weakly compact valued Pettis integrable pramarts in Banach space.

Very little work has been published on teaching for social justice in the Middle East. This paper demonstrates how a group of Arab women’s reading and writing of their world was facilitated by using a social justice pedagogy based on Gutstein’s (2006) model. The study involved 20 Middle Eastern women (ages ranging from 16-36). The findings suggest that the students have developed significant abilities to use mathematics as a tool to read and write their world. In addition, the findings show that, like their counterparts elsewhere in the world, these young women are also interested in social justice issues. This is particularly significant because of current ongoing social developments in the Middle East.

This study aims to examine how perceptions of corporate social responsibility (CSR) activities (i.e. environment, society and stakeholders) enhance perceived value, social media engagement to win customer loyalty in the hotel industry. In addition, it investigates the mediating effects of customer perceived value and social media engagement between CSR activities and customer loyalty.

A self-administered survey was conducted on customers in Malaysia. Based on the data collected from 389 customers, the analysis used the structural equation modelling (SEM) approach. The validity and reliability of the measurements were confirmed before the hypotheses of the study have been tested.

The results revealed that CSR related to the environment has significant direct and indirect impacts on customer loyalty. In addition, the effect of perceived value and social media engagement on customer loyalty has been supported. The results also demonstrated the mediating role of perceived value and social media engagement between CSR activities and customer loyalty.

This study advances the understanding of the impact of CSR activities, perceived value and social media engagement on customer loyalty in the hotel industry. Hoteliers can gain benefits by understanding how specific CSR activities can enhance customer perceived value and social media engagement value, thus leads to customer loyalty.

This study investigates the association between CSR activities, perceived value, social media engagement and customer loyalty, which has been lacking a full investigation in the hospitality literature.

El objetivo de este estudio es examinar cómo las percepciones de las distintas actividades de Responsabilidad Social Corporativa (RSC) (i.e., medio ambiente, sociedad y skateholders) mejoran el valor percibido por los clientes, su compromiso en medios sociales y su lealtad en la industria hotelera. También se investigan los efectos mediadores del valor percibido por el cliente y su compromiso en medios sociales sobre las relaciones entre las actividades de RSC y la lealtad.

Se realizó una encuesta autoadministrada a los clientes en Malasia. Tomando como referencia los datos recogidos de 389 clientes, se utilizó la metodología SEM. La validez y fiabilidad de las escalas de medida fueron confirmadas antes de contrastar las hipótesis del estudio.

Los resultados revelaron que sólo la RSC relacionada con el medio ambiente tiene un impacto, tanto directo como indirecto, sobre la lealtad de los clientes. Además, se han confirmado los efectos del valor percibido y el compromiso en medios sociales sobre la lealtad de los clientes. Los resultados también demostraron el papel mediador del valor percibido y el compromiso en medios sociales sobre la relación entre las actividades de RSC y la lealtad de los clientes.

Este estudio permite comprender mejor el impacto de las actividades de RSC, el valor percibido y el compromiso en medios sociales en la lealtad de los clientes en la industria hotelera. Los hoteleros pueden obtener beneficios al comprender cómo las actividades específicas de RSC pueden mejorar el valor percibido por los clientes y su compromiso en medios sociales y, por lo tanto, aumentar la lealtad de los clientes.

Este trabajo analiza la asociación entre las actividades de RSC, el valor percibido, el compromiso en medios sociales y la lealtad de los clientes, lo cual ha sido escasamente estudiado en la literatura sobre hospitalidad.

This study aims to empirically investigate the connection between Islamic finance and economic growth in Turkey using the endogenous growth model.

It applies quantile regression with the Markov chain marginal bootstrap resampling technique by adopting total Islamic financing as the main exogenous explanatory factor in the endogenous growth model, while the gross domestic product (GDP) is employed as a measure of economic growth. The sample consists of all full-fledged participation (Islamic) banks operating in Turkey spanning from 2013Q4 until 2019Q4. The study uses academic literature, official financial reports from the Participation Banks Association of Turkey, REDmoney Group, Islamic Financial Services Board (IFSB) and the International Monetary Fund (IMF) database.

The results show that Islamic finance is promoting economic growth in Turkey, which mirrors the success of the New Turkish Economy Program (2019–2021) which aims at boosting economic growth by enhancing the Islamic finance share in the Turkish banking sector and the global market.

Turkey has a dual banking system (conventional and participation (Islamic)) and both can influence the country's real economy. This study is limited to the influence of Islamic banking on Turkish economic growth. The study also restricts its size and coverage from 2013Q4 to 2019Q4, to cover the years over which data for all variables included in the research are available.

This paper suggests the adoption of the Turkish successful experiment as a path to reach economic growth by increasing the Islamic finance share in the banking industry for countries that seek to promote economic growth by Islamic finance, as the findings of this paper support.

This study is the first that examines the influence of Islamic finance on economic growth under a new theoretical framework of the endogenous growth model in Turkey using a robust non-parametric approach.

The empirical study of factors related to digital transformation (DT) in the banking sector is still limited, even though the importance of the topic is universally evident. To bridge that gap, this paper aims to explore the role of digital leadership (DL), innovative culture (IC) and technostress inhibitors (TI) to support engagement for improved digital innovation (DI). Based on the literature, these variables are crucial aspects of digitalisation, even though there is no agreement on their conclusiveness.

This quantitative study tested a new conceptual model using survey data from five major banks in Libya. Partial least squares structural equation modelling was used to analyse the data from the 292 usable responses.

The results showed that DL and IC positively affect DI. Techno-work engagement (TE) mediated the relationship between leadership, culture and innovation. TI played a significant moderating role in leadership, culture and engagement relationships.

The research findings highlight critical issues about how leadership style and fostering organisational support in the banking sector can enhance DT. Leaders must demonstrate a commitment to long-term resource allocation to avoid possible negative effects from digital stress while pursuing DI through work engagement.

The study suggests that fostering organisational support can enhance DT in retail banks, potentially leading to improved customer experiences and increased access to financial services. These programs will help banks contribute to societal and economic development.

This timely study examines predictor mechanisms of innovation in retail banking that resonate within the restrictions of organisational and DI frameworks and the social exchange theory. Exploring the intervening effect of TE in the leadership, culture and innovation associations is unprecedented.

This conceptual paper aims to explore government regulatory responses of social networking platforms (SNP) and tourism destination evangelism. This research draws on a two-phase data source review of government legislations that guarantee social media users and empirical papers related to social media platforms. The results revealed that Ghana has adopted specific legislations that manage and control SNP. To the best of the author’s knowledge, this study is the first of its kind that synthesized government legislation and empirical papers on social networking platforms in evangelising destinations which have been missing in extant literature.

Actions of incumbent politicians and firms’ managers during election years have been cited as sources of many problems that afflict economies and business entities. Given the controversies surrounding the impact of elections on firms’ soundness, this paper poses a question of whether banks should be averse to elections. Specifically, this study aims to investigate the impact of elections on the profitability and efficiency of banks.

Based on the authors’ knowledge, this is maiden analysis in this context for Ghana where relatively advanced appropriate GMM technique has been used on annual data from 2012 to 2016.

This study reveals that banks make higher returns in election years. Additionally, the authors report that government’s economic policies in election years are detrimental to management efficiency, though insignificant.

From an emerging economy perspective, this study would guide policymakers in designing policies that respond to, or minimize, the impact of elections on bank performance. The result of this analysis would also substantiate the market reaction to the changes in the economic, political and financial conditions.

This analysis suggests that firms’ performances in an election year depend on policies and political institutions in place. The authors argue that Ghana, with its exemplary democratic credentials and strong institutions, living alongside a high perception of corruption, is different. The contribution to literature is, first, by limiting this work to the banking sector of Ghana and, second, by incorporating the behaviors of incumbent governments and individuals in the regression specification model.

This paper examines the educational environment of indigenous Gulf Arab students at a UAE institution, many from rural families and with English skills that need further development. The influences on a group of freshman Engineering students, their developing learning skills and the coaching they are given is explored. Practical methods for motivating such students to cross boundaries of world-view and sentiment are discussed, whereby a focus is maintained on their personal context and objectives whilst aiming to achieve excellence in academic accomplishment. A pre-freshman stage is introduced to fill the language void, easing the transition between High School, College and University. A personal view is presented from an educator who himself is crossing many boundaries.

This study involved a group of Middle Eastern Muslim women (ages ranging from 16-36) learning mathematics through social justice pedagogy. One of the important lessons from this experience is that, despite some of the unique challenges associated with teaching for social justice, in this context this method of teaching is doable and beneficial. However, in the current atmosphere throughout the Middle East it is a very challenging task: it needs courage and commitment on the part of the teacher/researcher, as well as support and even protection by the head of the college or policymakers to ensure that it leads to positive learning outcomes.
