In the past few years, the concept of competitiveness developed by the World Economic Forum has become the focal point. Global competitiveness index (GCI) presents the constructs which are possible means of productivity of the country. The purpose of this study is to explore whether boosting the productivity of agriculture, services and industry sector is the possible channel of competitiveness leading to growth.

For this, panel GMM moderator model has been used for 16 low-income countries.

The results indicate that competitiveness helps agriculture and industry sector to become more growth productive, while it reduces the productivity of services sector.

This study urges that the gains from following the competition promotion policies overweigh the costs. Hence, low-income countries can break the low productivity trap.

Cilia serves numerous biological functions in the human body. Malfunctioning of nonmotile or motile cilia will have different kinds of consequences for human health. More specifically, the directed and rhythmic beat of motile cilia facilitates the unidirectional flow of fluids that are crucial in both homeostasis and the development of ciliated tissues. In cilia-dependent hydrodynamic flows, tapering geometries look a lot like the structure of biological pathways and vessels, like airways and lymphatic vessels. In this paper, the Carreau fluid model through the cilia-assisted tapered channel (asymmetric) under the influence of induced magnetic field and convective heat transfer is investigated.

Lubrication theory is a key player in the mathematical formulation of momentum, magnetic field and energy equations. The formulated nonlinear and coupled differential equations are solved with the aid of the homotopy perturbation method (HPM). The graphical results are illustrated with the help of the computational software “Mathematica.”

The impact of diverse emerging physical parameters on velocity, induced magnetic field, pressure rise, current density and temperature profiles is presented graphically. It is observed that the cilia length parameter supported the velocity and current density profiles, while the Hartman number and Weissenberg number were opposed. A promising effect of emerging parameters on streamlines is also perceived.

The study provides novel aspects of cilia-driven induced magnetohydrodynamics flow of Carreau fluid under the influence of induced magnetic field and convective heat transfer through the asymmetric tapered channel.

Fear of COVID-19 is a new workplace hazard that has made drastic changes at workplaces globally. Based on the conservation of resource (COR) theory, this research investigates the relationship between fear of COVID-19 and employee engagement. Furthermore, this study examines the moderating role of emotional stability in the relationship between fear of COVID-19 and employee engagement.

Data were collected using self-administrated questionnaires from bank employees located in different cities of Pakistan. PROCESS macro by Hayes et al. (2017) was used to analyze 267 valid responses.

Consistent with the hypotheses of this study, fear of COVID-19 was negatively associated with employee engagement. In addition, the moderating role of emotional stability was confirmed in the relationship between fear of COVID-19 and employee engagement. The findings of this study support the notion that fear of COVID-19 can be considered a workplace stressor that affects employee engagement. By contrast, emotional stability acts as a personal resource with a buffering effect.

This study investigates only the moderating mechanism in the relationship between fear of COVID-19 and work engagement. A self-reported questionnaire was used to collect the data. For future studies, other sources can be used to reflect the actual situation.

This study is currently relevant because of the sudden occurrence of the COVID-19 pandemic that has mentally and emotionally challenged the service employees. Unlike most prior studies, which investigated the impact of fear of COVID-19 on the health sector professionals, this study investigated the impact on the bank employees. Moreover, this study is among the first to provide insights on the role of employee's personality to maintain positive work attitudes during uncertain circumstances from COVID-19.

The pandemic's health and social issues have significantly altered the character and manner of teaching and learning in higher education across the country. The use of technology to replace or integrate face-to-face learning with online learning has become a necessary requirement for promoting and continuing learning processes. Furthermore, integrating technology is a goal of Sustainable Development Goal 4 (SDG 4) to make teaching and learning more innovative and sophisticated. This paper is based on a systematic review grounded in a synthesis of research papers and documents analyzing the current status of teachers' pedagogy through online learning modes in the context of Pakistan.

Through content analyses of academic studies in higher education and reflection on the online teaching experiences, this study discusses how students' learning is associated with teachers' teaching approaches in the modern era of digitalization and innovation.

The review and analysis suggest that online teaching is not viewed as an innovative phenomenon; rather, teachers simply teach their traditionally designed face-to-face courses through the use of technology. The paper suggests that transforming teachers' pedagogical insight to make online learning sustainable is an urgent need for higher education.

The analysis provides a basis for consideration of teacher learning and quality education (SDG #4) to fulfill the nation’s agenda for sustainable development. The analysis helps educators and administrators in higher education institutions reflect on their policies and practices that have short- and long-term effects on students' learning outcomes.

This study aims to address a comprehensive and integrated investigations pertaining to the preparation of AgNPs with well-defined nano-sized scale using the aforementioned poly (meth acrylic acid [MAA])–chitosan graft copolymer, which is cheap, nontoxic, biodegradable and biocompatible agent as a substitute for the traditionally used toxic reducing agents.

AgNPs are prepared under a range of conditions, containing silver nitrate and poly (MAA)–chitosan graft copolymer concentrations, time, temperature and pH of the preparation medium. To classify AgNPs obtained under the various conditions, ultraviolet–visible spectroscopy spectra and transmission electron microscopy images are used for characterization of AgNPs instrumentally in addition to the visual color change throughout the work. The work was further extended to study the application of the so prepared AgNPs on cotton fabric to see their suitability as antibacterial agent as well as their durability after certain washing cycles.

According to the current investigation, the optimal conditions for AgNPs formation of nearly 3–15 nm in size are 5 g/l, poly (MAA)–chitosan graft copolymer and 300 ppm AgNO₃ in addition to carrying out the reaction at 60°C for 30 min at pH 12. Besides, the application of the so prepared AgNPs on cotton fabric displayed a substantial reduction in antibacterial efficiency against gram-positive and gram-negative bacteria estimated even after 10 washing cycles in comparison with untreated one.

To the best of the authors’ information, no comprehensive study of the synthesis of AgNPs using poly (MAA)–chitosan graft copolymer with a graft yield of 48% has been identified in the literature.
