This study aims to focus on second grade fluid flow over a rotating disk in the presence of chemical reaction. Uniform magnetic field is also taken into account. Because of the smaller magnetic Reynolds number, induced magnetic field is negligible. Heat equation is constructed by considering heat source/sink.

Suitable variables are used to transform nonlinear partial differential equations to ordinary ones. Convergent series solutions are attained by applying homotopy analysis method.

Trends of different parameters on concentration, velocity and temperature are shown graphically. Skin friction coefficient and local Nusselt number are calculated and investigated under the effect of elaborated parameters. An elevation in the value of magnetic field parameter causes collapse in the velocity distributions. Velocity distribution in increasing function of viscoelastic parameter. Temperature and concentration profiles are decreasing functions of viscoelastic parameter. Concentration distribution reduces by increasing the chemical reaction parameter. There is more surface drag force for larger M, while opposite behavior is noted for β.

To the best of the authors’ knowledge, such consideration is yet to be published in the literature.

The purpose of this paper is to develop and standardize nutrient dense, easily digestible and affordable ready-to-eat supplementary foods from locally available ingredients for malnourished children and to assess their nutritional composition.

To develop supplementary foods, wheat and green gram were germinated, dried and made into flour. Potatoes of “Kufri Pukhraj” variety procured from university were washed, peeled, sliced, boiled, dipped in potassium metabisulphite solution, dried and grounded into flour. Spinach leaves were washed, dried and made into powder. Five wholesome ready-to-eat supplementary foods, namely, panjiri, mathi, seviyan, biscuits and pinni, were developed from germinated cereal, pulse and potato flour and spinach leaves powder. The products were standardized with potato flour and spinach leaves powder. The developed products were analyzed for proximate composition by standardized methods.

One-way analysis of variance and Tukey’s test was used to obtain differences in organoleptic scores within different levels of treatments. All five supplementary foods were acceptable at 30 per cent level of potato flour and 2.5 per cent level of spinach leaves powder. Mean scores of panjiri, mathi, seviyan, biscuits and pinni were significantly different (p < 0.05). Significant (p < 0.05) difference was observed in terms of moisture, crude protein, crude fat, crude fibre and ash content among the developed products.

The developed ready-to-eat supplementary foods can be recommended for supplementary feeding programmes running in the country.

The paper aims at the development of high energy protein supplementary foods for malnourished children. The developed complementary food blend is made up of variety of food groups like cereal, pulse, root and tuber and green leafy vegetables to provide wholesome nutrition to children. This is different to originally provided supplementary foods to children made up of only cereal. The developed products also add a variety to supplementary foods given to malnourished children in supplementary feeding programmes.

The purpose of this paper is to examine the relationship between Islamic work ethic (IWE) and employees’ attitude and behaviour in term of perceived organisational justice, psychological ownership (PSY), and employees’ performance in the Islamic financial institutions in Malaysia.

This study used a sample of 301 employees of Islamic financial institutions and employed structural equation modelling-partial least square technique in order to analyse the data.

The findings demonstrated that IWE has both direct and indirect effects on attitudinal as well as behavioural outcomes.

Managers who want to enhance their employees’ attitude and behaviour are strongly advised to give proper attention to the concept work ethic. Moreover, they need to conduct training programs to instil these values and to emphasise its crucial role in enhancing the effectiveness and efficiency of the organisation.

This study contributes to the body of knowledge on IWE by: testing its ability to predict employees’ performance, their perception of organisational justice, and their feeling of PSY, and examining the mediating effect of perceived organisational justice and PSY between IWE and employees’ performance.

It is widely evident that trust and commitment are important pillars for strengthening the relationship between financial service firms and their customers. However, it has not been explored how the service quality, perceived cost and role of agents are important for financial service firms. To overcome this gap, this study aims to investigate the role of service quality, perceived cost and the role of agents as the commitment–trust factors in the financial insurance service (Takaful) in Malaysia, enhancing customer satisfaction.

The study follows a quantitative design in which primary data was collected using a survey instrument. The measurement instrument was adapted from the previous research, and data were collected from 264 customers of the Takaful financial service organizations in Malaysia. The data were analyzed using variance-based structural equational modeling in Smart-PLS software.

This research has revealed several useful insights that demonstrate a significant impact on service quality, perceived cost and the agents’ role in forging close relationships with their customers. Corporate image has a moderating role in relationships and has significantly impacted takaful insurance companies. The results imply that regardless of the corporate image of the financial service organizations, customers are concerned about the prices and the quality of the agents’ services.

In this study, only the predictors such as service quality, perceived costs and agents’ roles as trust–commitment factors were examined to determine customer satisfaction. Other investigations are highly recommended, such as value co-creation in takaful, takaful customer experience and takaful trust. This study offers insights to takaful insurance companies on how to keep up a positive corporate image, which will boost their trust–commitment factors and ultimately increase customer satisfaction.

By presenting commitment–trust factors and company image in an identifiable framework, the current study has expanded the discussion on takaful financial insurance services. The methodology is developed and rigorously tested to gauge customer satisfaction in takaful financial service organizations’ context.

The purpose of this paper is to expand previous theories of motivation and religious ethics by examining the moderation effect of Islamic work ethic (IWE) on the relationship between perception of politics (POP) and job satisfaction, and turnover intention and negligent behavior (NB).

The sample consisted of 260 workers employed in various sectors in an Asian country. Multiple linear regression analyses were used to test the main effect of the five hypotheses. In addition, moderated models are used to identify factors (IWE) that may change the relationship between independent and dependent variables.

Results revealed that POP was negatively related to job satisfaction, and positively related to turnover intention and NB. IWE was positively related to job satisfaction, and negatively related to turnover intention (confirming previous research findings), and NB (a contribution of the current study). Furthermore, when the moderator variable of IWE was introduced to the relationship between POP and job outcomes, the influence and direction of the POP were altered (a major contribution of this study). In other words, the moderator variable strengthened job satisfaction and reduced both turnover intention and NB of organizational workers.

When the moderator variable of IWE was introduced to the relationship between the POP and job outcomes, the influence and direction of the POP were altered (a major contribution of this study).

The purpose of this study was to examine the process of the use of management’s positivity and negativity sources and their mediation on pharmaceutical members’ satisfaction that, in turn, enable a health-care organization to meet its business objectives with more agility.

Data were obtained from a survey of 106 pharmaceutical members regarding their relationships with management.

The results of LISREL analysis revealed that the use of positivity variables such as reward enhanced each of referent, expert and positive conflict; in addition, referent boosted satisfaction. However, the use of negativity variables such as opportunism enhanced power, but weakened each of referent, expert and legitimate power sources. The use of coercion enhanced power too, but produced dissatisfaction. Further, the prevalence of negative conflict caused dissatisfaction.

This study also reported major contributions when it examined the effect of the mediation of the use of positivity intrinsic power sources on satisfaction. It found that referent power functioned as a full mediator by dropping the amount of the relationship between the use of reward and satisfaction to zero and as a partial mediator by dropping the amount of the relationship between the use of coercion and satisfaction. In addition, the use of referent power mediated the joint effect of both the use of coercion and reward power sources, triggering a positive effect on satisfaction. Several managerial implications were discussed.

Applicable to telecom companies operating in Saudi Arabia, this study aims to investigate the mediating role of workplace dignity (WD) in the relationship between inclusive leadership and innovative work behavior (IWB) as well as the moderate role of workplace inclusion (WI) in said relationship.

A total of 364 telecom companies in Saudi Arabia participated in the survey study. SmartPLS was employed to evaluate the data and test the research variables.

According to this study, inclusive leadership has a favorable impact on IWB. Additionally, the study concluded that inclusive leadership enhances WD. Furthermore, the authors discovered that WD has a favorable impact on IWB. The findings showed that the association between inclusive leadership and IWB is mediated by WD. Finally, WI has a statistically positive moderating effect between WD and IWB on the moderation side of the analysis.

This study is the first to consider WD as a mediator in the relationship between inclusive leadership and IWB. Examining WI's role as a moderator also deepens the authors' comprehension of the connection between WD and IWB.

The purpose of this study is to test the relationship between mall relevance dimensions [(functional relevance (FNR), symbolic relevance (SYR), social relevance (SOR) and environmental relevance (ENR)] and shoppers' well-being (SWB), which in turn influences mall loyalty (ML). In addition, this study aims to investigate the moderating effect of social media celebrities (SMCs) on the association between SWB and ML.

A mall intercept survey was used to collect responses from mall shoppers. The authors received 426 valid responses from mall shoppers in Pakistan's three metropolitan cities (i.e. Karachi, Lahore and Islamabad). To test the hypotheses, partial least squares structural equation modelling (PLS-SEM) was used.

Findings reveal that FNR, SYR, ENR and SOR significantly and positively influence SWB. Similarly, SWB significantly affects ML. Moreover, SMCs moderate the positive relationship between SWB and ML.

This study is one of the pioneer studies examining mall relevance dimensions on SWB. In addition, this study contributes to the retailing literature by testing the moderation effect of SMCs on the relationship between SWB and ML. Likewise, this study provides insights for mall administration to focus on mall relevance in terms of FNR, SYR, ENR and SOR to enhance the current and prospects' SWB. Next, SMCs play a key role in enhancing SWB and ML.

This study investigated the factors affecting online learning (OL) and stress and anxiety (SaA) during the COVID-19 pandemic in Saudi Arabia.

This study used a quantitative study and a survey questionnaire to collect the cross-sectional data. The authors sent 500 survey questionnaires to the respondents of which 262 samples were returned. This represented a 52% response rate. Finally, this study used 260 valid samples to derive this study’s findings.

Through structure equation modelling analysis, this study’s findings demonstrate that lack of time and support, technical problems and lack of technical skills negatively affect OL. In addition, this study’s findings show that cost and access to internet has a significant effect on OL. Finally, this study’s findings show that among Saudi Arabian university students OL is the significant predictor of SaA.

This study’s findings offer university authorities meaningful ways to identify replacements for the usage of harmful devices to lessen psychological problems during the COVID-19 pandemic. By pointing out students’ significant challenges and barriers during OL, this study’s findings support the smooth and parallel running of OL. Such challenges cause deprivation and frustration among the students. Therefore, to some extent, it may be a violation of their human rights. In this way, this study’s findings demonstrate how to overcome these violations.

By exploring the significant challenges faced by Saudi Arabian university students, this study’s findings offer an original and empirical contribution to the literature.

Building on the resource-based view (RBV) and the theory of other orientation, this study aims to examine the association between Islamic work ethics (IWEs) and organizational performance highlighting the role of employee relations climate as an underlying mechanism.

Data were collected from 239 employees working in diverse sectors in the state of Qatar. Structural equation modeling of partial least squares was used to analyze the data of the study.

The results suggest that IWEs positively impact organizational performance and employee relations climate. Furthermore, employee relations climate demonstrated to play a mediating role in the IWEs-organizational performance link.

The study can be used by administrators pertaining to the importance of IWE and employee relations climate to cultivate higher organizational outcomes such as organizational performance.

This research is distinctive as it examines the connection between IWEs and organizational performance in Qatar, a country where the influence of Islamic values and beliefs on work ethics is profound. In addition, the research sheds light on a topic that has received little attention in the literature: the significance of the workplace climate in determining how IWEs affect organizational performance. Finally, the research integrates two important theoretical frameworks, the RBV and the theory of other orientation, to create a comprehensive model that explains the complex relationship between IWEs, employee relations climate and organizational performance.
