The paper investigates the dynamic relationship among the stock markets of South Asian Association of Regional Cooperation (SAARC) countries during the COVID-19 pandemic.

Daily time-series data of four SAARC countries: India, Bangladesh, Pakistan, and Sri Lanka, from February 13th, 2013 to March 31st, 2021 are used. The study considers stock prices prior to the blowout of COVID-19 and during the onset of the pandemic. The novel estimation procedure of the autoregressive distributed lag model is used while the results are also confirmed by post-estimation techniques.

The study confirms that the COVID-19 contagion has adversely influenced the stock returns of SAARC countries. The findings signify that the pattern of cointegration has significantly different regularities in the pattern of causality in the long run and short run during the COVID-19 crisis. Overall, the study revealed that the COVID-19 pandemic has weakened the dynamic connection among the stock markets of SAARC countries.

To dampen uncertainties generated by the COVID-19 pandemic, the authorities and central banks should be equipped with efficient strategies and guidelines to cope with the crisis created by the pandemic. Further, governments should focus on assuaging the panic faced by investors and enhancing the confidence of domestic as well as foreign investors. Further, the weakened integration of financial markets during the crisis offers opportunities for speculative and arbitrage gains for investors.

The research work is an innovative effort to analyze the impression led by COVID-19 on the SAARC stock markets integration.

The purpose of this paper is to investigate the effect of anisotropy in terms of a single parameter indicating strengthening or weakening in the tangential direction in composite disc with hyperbolically varying thickness introduced presumably by processing or due to alignment of dispersed reinforcements during flow of the matrix.

Mathematical model to describe steady-state creep behavior in an anisotropic rotating disc made of Al-SiCp composite containing 30 vol% of SiC particles. The creep behavior of the composite has been described by Sherby's law. The creep parameters in the law have been determined using the regression equations developed on the basis of available experimental results in the literature. Stress and strain rate distributions for isotropic disc (a=1) have been compared with those obtained for anisotropic composites with characteristic parameters a=0.7 and 1.3.

The study revealed that the change in the stresses by anisotropy in composite disc is relatively small while anisotropy introduces significant change in the strain rates. It is concluded that the radial strain rate always remained compressive for the isotropic composite as well as the anisotropic disc with a greater than unity (a=1.3). However, it becomes tensile in the middle region of the disc when it is less than unity (a=0.7). If a is reduced from 1.3 to 0.7, the variation of tensile strain rate in the tangential direction remains similar, but the magnitude reduces, i.e. the strength in tangential direction is enhanced.

This study puts forward an analytical framework for the analysis of creep stresses and creep rates in an anisotropic rotating disc with hyperbolically varying thickness.

The learning outcomes of this paper is as follows: to identify unique selling points of a growing business for attaining competitive advantage; to understand the role of segmentation for Wellness Zone Headmasters (WZH); to explore different strategic choices for successful expansion of business; to help students understand the concept of customer satisfaction in a competitive industry; and to understand the importance of differentiation as a major deciding factor for the future of a business.

In March 2020, Kumud Goel, one of the directors of WZH, a chain of wellness spa and salon in Jammu and Kashmir (India), was considering different marketing strategies to grow her existing business. The company had opened two new outlets in the past two years and was looking at increasing its customer base. Kumud was concerned about keeping her customers satisfied in a highly competitive industry. She was aware that differentiation was critical for future growth. In what ways could WZH differentiate itself from its competitors at a time when the market was exploding? Could customer segmentation be the solution? What measures would WZH need to take to increase its repeat customers?

The case is appropriate for use in a 90-min class in a Masters in Business Administration-level management course and for undergraduates, especially marketing majors and in a module on marketing strategy and customer value.

The case helps to understand: the working mechanisms of a digitized salon service, with a focus on the lower- and middle-income strata. The changing scenario of the service marketing model, with the growth in digital service models. To investigate the organisational challenges of a digitally facilitated/based start-up and find solutions to overcome the challenges.

“Yes Madam”-salon at home was a business enterprise, providing beauty and wellness services at the doorstep through a mobile application and web-based platform. The case describes the reason for opening the doorstep beauty services, its revenue model and aims to provide quality services to lower- and middle-income strata. The case will help students to understand the working mechanism of digitized salon services and associated challenges; prominent ones being attracting, selecting and retaining the beauticians and providing the standardised services. The case has examined the low-price services for the consumers delivered by the company. The case also discussed their plans for diversification and penetration into the untapped markets.
