Abstract
Purpose
This paper aims to examine the squeezing flow of hybrid nanofluid within the two parallel disks. The 50:50% water–ethylene glycol mixture is used as a base fluid to prepare Ag–Fe_3O_4 hybrid nanofluid. Entropy generation analysis is examined by using the second law of thermodynamics, and Darcy’s modal involves estimating the behavior of a porous medium. The influences of Viscous dissipation, Joule heating and thermal radiation in modeling are further exerted into concern.
Design/methodology/approach
For converting partial differential systems to ordinary systems, a transformation technique is used. For the validation part, the numerical solution is computed by embracing a fourth-order exactness program (bvp4c) and compared with the analytical solution added by the homotopy analysis method (HAM). Graphical decisions expose the values of miscellaneous-arising parameters on the velocity, temperature and local-Nusselt numbers.
Findings
Hybrid nanofluid gives significant enhancement in the rate of heat transfer compared with nanofluid. The outcomes indicate that the average Nusselt number and entropy generation are increasing functions of the magnetic field, porosity and Brinkman number. When the thermal radiation rises, the average Nusselt number diminishes and the entropy generation advances. Furthermore, combining silver and magnetite nanoparticles into the water–ethylene glycol base fluid significantly enhances entropy generation performance.
Originality/value
Entropy generation analysis of the magneto-hydrodynamics (MHD) fluid squeezed between two parallel disks by considering Joule heating, viscous dissipation and thermal radiation for different nanoparticles is addressed. Furthermore, an appropriate agreement is obtained in comparing the numerical results with previously published and analytical results.

Abstract
Purpose
This paper aims to study the perception of school students towards online classes via virtual meeting applications and to unravel the teachers' preparedness and students' preparedness for running synchronous online classes and its impact on student's engagement and their satisfaction during the period of lockdown due to COVID-19.
Design/methodology/approach
On the basis of focused group discussions with teachers and students of top 10 private CBSE affiliated schools (National capital Region, Delhi, India), survey instrument was constructed. Further, 489 valid responses were finally analysed through partial least square (PLS) method and structural model was tested.
Findings
All the six independent variables such as teachers' structured approach, teachers' technical readiness, teachers' self-efficacy, students' technical readiness, students' autonomy and students' self-efficacy influenced students' engagement and satisfaction towards synchronous online classes significantly. The result of the structural model also reveals that students' engagement is a significant predictor of students' satisfaction.
Research limitations/implications
The paper outlines the scope for future research in ascertaining more critical success factors other than satisfaction and engagement. Scope of this research suggests inclusion of not only schools but framework is also important for college and university level educational bodies. Data collection was confined to students only whereas viewpoint of teachers and parents may also be included.
Originality/value
This study devised a collaborative form of learning where both the parties learnt while making continuous interactions and also co-created value in terms of new skills. Provision of autonomy given to students can't be overlooked as an important indicator for his/her preparedness. As a result, students feel motivated to get engaged in the whole process which makes them satisfied and will be able to identify the learning outcomes equal to or greater than in physical classroom settings.

This study aims to present dual band reconfigurable MIMO antenna for 5G (sub-6 GHz) and WLAN applications.
Abstract
Purpose
This study aims to present dual band reconfigurable MIMO antenna for 5G (sub-6 GHz) and WLAN applications.
Design/methodology/approach
To achieve optimum bandwidth, radiation pattern and radiation efficiency, the defected ground structure (DGS) and a rectangular stub connected with the DGS are used. To further cover the sub-6 GHz spectrum (3.4–3.6 GHz) for future 5G communications, a two-element multi-input multi-output (MIMO) antenna configuration is designed by using the single element antenna. The proposed reconfigurable MIMO antenna using a PIN diode is designed on an FR4 substrate with a dielectric constant of 4.4 and a loss tangent of 0.02 and a 35 × 20 × 1.6 mm3 dimension.
Findings
The proposed antenna achieved dual operating bands of 3.4–4.1 GHz (5 G sub-6GHz applications) and 4.99–5.16 GHz (WLAN application) in the D = ON state. For D = OFF state, the proposed antenna achieved 3.55–3.65 GHz and 3.66–4.05 GHz frequency bands for 5G (sub-6GHz) applications. In terms of the envelop correlation coefficient, diversity gain, mean effective gain, total active reflection coefficient and isolation between the ports, the proposed antenna’s diversity performance characteristics are investigated and the obtained values are 0.05, 9.9 dB, ±3dB, −4dB, −15dB, respectively.
Research limitations/implications
The fabricated prototype antenna on FR4 substrate has measurable parameters that are in good agreement with the simulated findings. Due to hardware design limitations, there is a minor difference between software and hardware results.
Originality/value
The proposed MIMO antenna is compact and reconfigurable for 5G (sub-6GHz) and WLAN applications, and from the graph, the measurements and simulations have been found to be in close agreement.

Abstract
Purpose
Women empowerment is essential for the growth and development of the nation. This study aims to identify the role of non-government organisations (NGOs) in promoting women empowerment through immediate livelihood facilities. Women are creative enough to start their own venture, but they are not able to explore the available opportunities because of male dominance, lack of education and proper government support. Thus, NGOs play a major role in training and empowering women to attain immediate livelihood.
Design/methodology/approach
The role of NGOs in empowering women has been explored using the case study method. A total of five case studies of women who attained training and started their own venture have been developed using in-depth interviews.
Findings
Women empowerment occurs through venture creation and entrepreneurship, which can be attained with proper training and information. Motivation and effective leadership help women in gaining confidence, and they aim to achieve their goals. Proper information about government policies, networking with customers, relationship with self-help groups (SHGs) and NGOs also help them in attaining empowerment.
Practical implications
This study indicates to the government and researchers that, instead of initiating new policies, it is important to focus on the existing policies and improve them. NGOs or SHGs must focus on providing immediate livelihood through venture creation or entrepreneurial activities.
Social implications
Women need to be more socialised and develop a habit of partnership with their friends and neighbours to extend their ventures (Dixit et al., 2020). To meet the demand of sustainable and green environment, women must be trained about green manufacturing and to prepare products which are environmentally friendly and sustainable (Agarwal et al., 2020). Instead of initiating new policies, government must review their existing policies and provide equal opportunities to increase female workforce.
Originality/value
This study focusses on the role of NGOs in empowering women by focussing on their immediate livelihood through venture creation or entrepreneurship.

Abstract
Purpose
The purpose of the paper is to identify existing and common critical success factors adapted for implementing Industry 4.0 technology, which is essential to survive in the vulnerability, uncertainty, complexity and ambiguity (VUCA) environment by using systematic literature review (SLR) methodology with the preferred reporting items for systematic reviews and meta-analyses (PRISMA) and content analysis strategy.
Design/methodology/approach
The SLR methodology with the PRISMA and content analysis strategy adapted to review 74 papers in peer-reviewed academic journals and industry reports published from 2014 to 2021.
Findings
Based on a review of relevant literature, two theoretical contributions have been added to the literature on Industry 4.0. First, this review reveals that 35 (47%) out of total 74 studies assessing the Industry 4.0 implementation in the manufacturing industry, the service industry can also create value through Industry 4.0 implementation, with a lot of potential to increase productivity, which literature has not explicitly focused on. Second, this paper proposes the 12 most common critical factors (training and development, organizational culture, top management support, organizational structure, innovation capability, technological infrastructure, security system, standardization of procedures, financial resources, communication and cooperation, change management and governance) that can be considered as the significant critical factors for successful implementation of Industry 4.0.
Originality/value
The novelty part related to methodological perspective by using the PRISMA approach for systematic review, which cannot be found extensively in existing literature in the context of the Industry 4.0 phenomenon to analyze critical factors.

Abstract
Purpose
The paper aims to clarify the relationship between organizational work-family practices and employee work-family conflict in light of the boundary conditions of commitment-based human resource management (HRM) and employee human capital.
Design/methodology/approach
The paper opted for a multi-source, multi-level design and surveyed 1,717 individuals (including CEOs, HR managers and employees) from 159 firms in China. The model was tested using hierarchical linear modeling.
Findings
The paper provides empirical insights that the effect of work-family practices on work-family conflict is indispensably dependent on the adoption of commitment-based HRM. In addition, employee human capital further moderated this interaction in that the effect of work-family practices on reducing work-family conflict was most salient with high-education employees who were embedded in a high-commitment HRM system.
Research limitations/implications
Testing the hypotheses in the Chinese context has both its merits and drawbacks. Specific results are pursuant to the Chinese context. Therefore, a cross-cultural comparative study is called upon.
Practical implications
The paper includes implications for organizations striving to minimize employee work-family conflict.
Originality/value
This paper primarily applies the resource-building perspective to examine the synergistic effects of organizational resources (targeting work-family practices together with general commitment-based HRM) and individual intellectual resources (human capital) on employee work family conflict.
