This paper aims to enhance the existing literature on adaptive market hypothesis (AMH) as this study first time links the month of Ramadan with AMH that permits the performance of well-known Ramadan effect to fluctuate over time.

To fulfill the purpose, the authors inspect the daily returns of 107 individual firms listed at Pakistan Stock Exchange over the period of 20 years. To explore the varying degree of return predictability during Ramadan, the authors use four different subsamples comprising equal length of observations of five years each. The authors use a GARCH (1,1) regression model which facilitates for time varying nature of volatility in equity returns. To facilitate the non-normal nature of stock return data, the authors use Kruskal–Wallis test statistic.

The authors find that behavior of Ramadan effect evolves over time, as performance of this effect varies from time to time and consistent with AMH. Finally, the paper proposes that AMH is well elucidation of behavior of Ramadan effect than traditional efficient market hypothesis.

First limitation is related to the choice of sub-sample as the study uses a sub-sample of five years. Second, the authors ignore transection cost (commissions, fee and taxes) as it is freely negotiated and varies between 4 and 10% (Khan, 2013). Due to such varying information we ignore the transaction cost. It is suggested that a sub-sample analysis of long period may be a more appropriate method to elucidate the idea of AMH in future research and suggest the current method could be adapted and helpful to examine other calendar and market anomalies in different equity markets.

The paper includes implications for investors to choose a better model for investment. Investors can exploit greater returns in future month of Ramadan periods. Furthermore, the researchers can easily extend the methodology used in the study to address multiple issues like adaptive behavior of returns from bonds, real estate investment trusts, cryptocurrencies and trading rules of strategies.

Study confirms from sample t-test and GARCH (1,1) model that Ramadan effect is present in the full and in certain sub-samples; therefore, based on these discrepancies investors can earn abnormal returns by developing specific investment strategies as investors usually make investments in share according to the religious context of Islamic Calendar. The results provide good references for suitable time of investment in stock market. The findings of this study will be helpful to investors and brokers as well as portfolio managers to capture favorable returns across the Islamic calendar.

The paper identified need to study why behavior of Ramadan effect varies over time. The data set comprises daily returns of 107 individual companies over the period of 20 years to better investigate the varying nature of anomalous effect of month of Ramadan. The findings are valuable for international investors and portfolio managers.

The purpose of this paper is to identify the major factors of client satisfaction (CS) that are critical for web development projects in freelance marketplaces. This quantitative study is done from the point of view of the web development services clients. Five major dimensions were proposed as determinants of CS from the literature review: ease of use, user interface, information, security and privacy.

A web-based survey methodology is used as the main data collection instrument. Statistical techniques such as confirmatory factor analysis and multiple linear regressions are used to analyze 162 responses of questionnaires.

The findings suggest that all factors do influence CS. In terms of strength, security had the highest level of impact on CS, so it is the strongest determinant among all factors. After security, ease of use and information are considered as strong determinants. So, this study concludes that the five major determinates do affect CS in web development projects from freelance marketplaces.

This research is limited only to the top freelance marketplaces, such as Upwork, Freelancer, Fiverr, Guru, Envato Studio, etc. The sample size is relatively small and this study is focused on web development projects only. Moreover, this research is focused only on the characteristics or attributes of the projects final outcome, i.e. website.

This study attempts to identify the important factors that have a relation with CS, thus giving freelancers an indication of what to look for when working on any web development project posted by any client in a freelance marketplace. Understanding the determinants of CS will also help Pakistani information technology freelancers involved in web development projects and services to increase their project performance, improve their CS rate and increment client following.

This presents the first study on the determinants of CS in web development projects from freelance marketplaces.

Roles and responsibilities of higher education academics (educators) have dramatically changed since COVID-19 outbreak. Considering this, the present study applies servant leadership and social cognitive theories to test three determinants of pedagogical resilience, i.e. servant leadership, professional self-efficacy and workplace thriving. The study also tests moderation of professional self-efficacy between servant leadership and pedagogical resilience.

Applying snowball sampling, time-lagged data were collected on T1 and T2 through survey questionnaire from 205 employees of six higher education institutes (HEIs) in Sindh, Pakistan. For data analysis, the study employed structural equation modeling using SmartPLS.

Results indicate that servant leadership and professional self-efficacy predict pedagogical resilience of educators. Moreover, professional self-efficacy moderates the relationship between servant leadership and pedagogical resilience.

This study has a few limitations. The study was conducted in HEIs of Pakistan, which are non-profit organizations. Given this, generalizability of findings in profit-making organizations is suggested with caution. Cross-cultural and cross-regional generalizability may also be challenging.

Training, coaching and role modeling may improve efficacy of educators, which is vital to pedagogical resilience. Furthermore, servant leadership attributes (i.e. emotional support and empathy) may also enhance resilience. Rolling-out tailored training programs for boosting professional efficacy of existing faculty could be helpful in building pedagogical resilience. Fostering a culture of teamwork through adopting collaborative and state of the art educational technologies could also enhance self-efficacy, which is vital to resilience. This could be done when vice chancellors, rectors, HODs, etc., adopt servant leadership attributes to play their role by navigating a paradigm shift from traditional teaching platforms and physical meetings to digital educational tools.

Post-pandemic educational management necessitates resilient workforce to handle any uncertain situation. Given this, the authors apply servant leadership and social cognitive theory and introduce a novel construct of “pedagogical resilience”. This paper offers unique theoretical contributions and suggests universities/HEIs to adopt servant leadership model and foster professional self-efficacy of educators for boosting their pedagogical resilience in times of uncertainty. Pedagogically resilient educators may be well equipped to adopt venerable pedagogical competencies, and could contribute significantly to the quality of higher education.

The purpose of this paper is to explore the effect of Islamic religiosity on consumer attitudes toward Islamic banking in Egypt.

The study utilizes a mixed-methods approach, employing both qualitative in-depth interviews and quantitative surveys.

The main findings of the study show that religiosity has an impact on consumer attitudes toward Islamic banking in Egypt. Major religiosity clusters were identified from the sample and these were associated with attitudes toward Islamic banking.

The findings of this research are of practical importance for marketers in Islamic banks, as they reflect on the likely role religiosity would play in shaping the attitudes of potential customers toward their products. Thus, marketers can use the religiosity scale in measuring intention to use their banking services.

The study was implemented in Egypt, where the volume of research on this topic is very limited; thus the context of the study is of value to researchers and practitioners and it can serve as a base for future studies in the Middle East region.

The purpose of this study is twofold. First, this research explores the level of Islamic financial literacy of customers in the context of Islamic banking. Second, this study examines the determinants of customer adoption of Islamic banking in Turkey.

This study gathered sample data from 409 participants determined using the purposive sampling method. In the study, first, the reflective measurement model is used to examine the reliability, validity and multicollinearity problems of the variables. Then, AMOS structural equation model (SEM) is used to reveal the relationship between Islamic financial literacy and Islamic banking services. Additionally, this study performed both descriptive and inferential analysis to understand customer literacy about Islamic banking and their adoption behavior of Islamic banking.

The results obtained from descriptive assessment indicate that Turkish customers of Islamic banking possess sufficient literacy about Islamic banking. Moreover, the results from SEM indicate that the adoption of Islamic banking by customers is significantly predicted by the role of Sharia Board management, Islamic banking and purpose of financial institution, religious factor and legitimacy of Islamic financial system.

This study focuses only on the level of knowledge and perceptions of customers who have accounts in Islamic banks or financial institutions in Turkey. It does not focus on the level of knowledge and perception of Muslims who do not have accounts in Islamic banks and financial institutions.

Previous studies on Islamic banking are mostly studies that investigate customers’ perceptions of the Islamic banking system and why individuals prefer Islamic banks. In particular, studies examining the relationship between individuals’ Islamic financial literacy level and Islamic banking preferences are limited. This study is considered to be an original study as it investigates the relationship between the Islamic financial literacy level of individuals and their adoption of Islamic banking services in Turkey.

This study aims to explore how job performance (EJP) is affected by employees’ perception of organizational politics (POP). It also investigates the mediating roles of workplace stress (WS) and counterproductive work behavior (CWB).

Data was gathered from employees working in category (A) travel agencies and five-star hotels in Egypt. A partial least squares structural equation modeling analysis was conducted using 468 valid responses.

The findings indicate that there is a negative correlation between POP and EJP. Additionally, there is a positive correlation between POP and CWB as well as WS. The results also demonstrate a negative correlation between WS and CWB with EJP. Moreover, the findings suggest that CWB and WS act as partial mediators in the relationship between POP and EJP.

The research included some ground-breaking investigations. Currently, research on the effects of POP on CWB, WS and EJP is insufficient. As well, the current study attempts to measure the mediating role of CWB and WS in the link between POP and EJP. The current study has filled a gap in the tourism and hospitality literature, human resources management literature and organizational behavior literature by empirically analyzing these links in the context of Egyptian hotels and travel agencies.

本研究旨在探讨员工对组织政治（POP）的看法如何影响工作绩效（EJP）。它还调查了工作场所压力（WS）和适得其反的工作行为（CWB）的中介作用。

调查收集了埃及 (A) 类旅行社和五星级酒店员工的反馈。对 468 个有效回复进行了 PLS-SEM 分析。

结果显示, POP与员工工作绩效呈负相关, 此外, POP与反生产力工作行为和工作场所压力呈正相关。研究结果还表明, 工作场所压力和适得其反的工作行为与员工的工作绩效之间存在负相关关系。此外, 研究结果表明 CWB 和 WS 调节 POP 和 EJP 之间的关系。

该研究包括一些开创性的调查。目前, POP对CWB、WS、EJP影响的研究还不够。从上下文相关性的角度来看, 无法对酒店和旅行社中这些变量之间的联系进行实证分析。当前的研究通过在埃及酒店和旅行社的背景下对这些联系进行实证分析, 填补了旅游和酒店文献、人力资源管理文献和组织行为文献的空白。

Este estudio pretende explorar cómo el desempeño laboral (EJP) se ve afectado por la percepción que tienen los empleados de la política organizativa (POP). También investiga los papeles mediadores del estrés laboral (WS) y el comportamiento laboral contraproducente (CWB).

Se recopilaron datos de empleados que trabajaban en agencias de viajes de categoría (A) y hoteles de cinco estrellas en Egipto. Se realizó un análisis de Modelización de Ecuaciones Estructurales por Mínimos Cuadrados Parciales (PLS-SEM) utilizando 468 respuestas válidas.

Los resultados indican que existe una correlación negativa entre POP y EJP. Además, existe una correlación positiva entre POP y CWB, así como WS. Los resultados también demuestran una correlación negativa entre WS y CWB con EJP. Además, los resultados sugieren que CWB y WS actúan como mediadores parciales en la relación entre POP y EJP.

La investigación incluye algunas investigaciones pioneras. En la actualidad, la investigación sobre los efectos de la POP en la CWB, la WS y la EJP es insuficiente. Además, el presente estudio intenta medir el papel mediador de la CWB y la WS en el vínculo entre la POP y la EJP. El presente estudio ha llenado un vacío en la literatura sobre turismo y hotelería, en la literatura sobre gestión de recursos humanos y en la literatura sobre comportamiento organizativo al analizar empíricamente estos vínculos en el contexto de los hoteles y agencias de viajes egipcios.

This paper aims to examine the mediating role of environmental concern in the relationship of green purchase awareness and purchasing behavior of fast food consumers keeping in view the theory of planned behavior.

A quantitative, cross-sectional design is used by collecting primary responses through a validated questionnaire. In all, 1,008 male and female buyers of fast food were sampled. Structural equation modeling is applied.

The results revealed that green purchase awareness has a positive relationship with green purchase behavior, and environmental concern has no mediation in the relationship. Upon having awareness, the respondents adopted green or pro-environmental behavior, but at the same time, they were found having least concern for the protection of environment.

This is a cross-sectional study with questionnaire. Multiple sources of data collection results in weakening self-reporting bias.

Implications count toward individuals, enterprises and society at general.

The study highlights the issue of not having concern for the protection of the environment even after having green purchase awareness. This is the first time the environmental concern is examined as a mediator in the selected relationship. The contradictory results of having no environmental concern differentiate this study from others.

Islamic banking (IB) has witnessed remarkable growth in the past decade. The purpose of this study is to explore some factors that are influencing the choice of Islamic banking and finance (IBF) products and services in the United Arab Emirates (UAE), a predominantly Muslim country.

Students enrolled at a university located in a major emirate in the UAE were asked to respond to a survey on factors underlying their decision to open an account at an Islamic bank. Responses were analyzed using descriptive statistics, analysis of variance and regression analysis.

Results indicate that the decision to open an account with an Islamic bank is influenced by consumer expectations regarding the conformity of the bank’s operations with Islamic principles, as well as consumers’ Arab language skills. Variables such as consumers’ nationality, gender, education and familiarity with IB do not have a significant influence on the decision to open an account at an Islamic bank.

The study focuses on university students from a certain Emirate only, which somewhat limits the generalizability of the research results. Nevertheless, the findings of this study may potentially provide some practical insights for further improving and promoting IB, with special reference to the UAE youth market segment.

The research is original in nature, particularly as there have not been many instances where the choice of potential consumers (university students) regarding IB and finance services has been explored within the IB sector in a predominantly Muslim nation such as the UAE, an emerging Gulf economy. Consequently, the research findings have important implications for Islamic banks operating in a predominantly Islamic environment.

This study aims to investigate the effect of organizational ambidexterity (OA) and organizational green culture (OGC) on corporate sustainability (CS) while incorporating the mediating role of green innovation (GI) to provide a detailed insight into CS. The study also presents a research framework based on the Organizational Ambidexterity theory and Natural Resource-based view to explain the factors contributing to CS.

Using stratified sampling, the study collected data through survey-based empirical research from 307 textile companies registered with the Securities and Exchange Commission of Pakistan (SECP) or the All-Pakistan Textile Mills Association (APTMA). The collected data were analysed using path analysis, mediation analysis and moderation analysis through smart PLS-SEM version 4.0 to assess the composition and causal association of factors.

The study found a significant relationship between OA and OGC with CS. Furthermore, the study revealed that green innovation partially mediates the relationship between OGC and CS. The proposed research framework can be valuable for promoting and recommending actions to enhance CS.

The study on CS in the textile sector of Pakistan has limitations such as a narrow focus, cross-sectional design and reliance on self-reported data. Future research should explore additional factors, conduct longitudinal research, investigate contextual factors, scrutinize specific green innovation practices and broaden the scope of the study to include SMEs and other textile organizations.

The research framework can help senior executives to foster CS by promoting OGC, OA and GI. Practitioners and academicians can also utilize or further investigate the proposed framework for validation and to foster CS.

This study fills gaps in the existing literature by investigating the mediating effect of GI between OGC and CS. The proposed research framework provides a comprehensive understanding of the factors contributing to CS based on the Organizational Ambidexterity theory and Natural Resource-based view.
