This study aims to analyse the behaviour of plane waves within a nonlocal transversely isotropic visco-thermoelastic medium having variable thermal conductivity.

The concept of enunciation is used in the generalized theory of thermoelasticity in accordance with the Green–Lindsay and Eringen’s nonlocal elasticity models. The linear viscoelasticity model developed by Kelvin–Voigt is used to characterize the viscoelastic properties of transversely isotropic materials.

It has been noticed that three plane waves, which are coupled together, travel through the medium at three different speeds. The derivation of reflection coefficients and energy ratios for reflected waves is carried out by incorporating suitable boundary conditions. Numerical computations are performed for the amplitude ratios, phase speeds and energy partition and displayed in graphical form.

The outcomes of the numerical simulation demonstrate that the amplitude ratios are significantly influenced by variable thermal conductivity, nonlocal parameters and viscosity. It is further observed from the plots that the phase speeds in a transversely isotropic medium depend on the angle of incidence. In addition, it has been established that the energy is preserved during the reflection phenomenon.

The purpose of this paper is to study the transient thermoelastic interactions in a nonlocal rotating magneto-thermoelastic medium with temperature-dependent properties. Three-phase-lag (TPL) model of generalized thermoelasticity is employed to study the problem. An initial magnetic field with constant intensity acts parallel to the bounding plane. Therefore, Maxwell's theory of electrodynamics has been effectively introduced and the expression for Lorentz's force is obtained with the help of modified Ohm's law.

The normal mode technique has been adopted to solve the resulting non-dimensional coupled field equations to obtain the expressions of physical field variables.

For uniformly distributed thermal load, normal displacement, temperature distribution and stress components are calculated numerically with the help of MATLAB software for a copper material and the results are illustrated graphically. Some particular cases of interest are also deduced from the present study.

Influences of nonlocal parameter, rotation, temperature-dependent properties, magnetic field and time are carefully analyzed for mechanically stress free boundary and uniformly distributed thermal load. The present work is useful and valuable for analysis of problem involving thermal shock, nonlocal parameter, temperature-dependent elastic and thermal moduli.

In this global digital era, health-care companies are increasing their presence on the internet through branded content that serves as a connecting link between customers and brands. However, there is a limited understanding of branded content’s impact on customers. Thus, this paper aims to empirically analyse customer engagement for branded content in the health-care sector.

The factors impacting customer engagement for branded content were identified and analysed using the Decision-Making Trial and Evaluation Laboratory approach to get their significance and the cause and effect relationship.

It emerged that co-creation is the most significant factor, having a substantial relationship with all other factors. It is substantiated that health-care companies can increase the intensity of customer engagement by delivering more authentic and relevant content and having an appealing look in a time-bound manner. This will increase the usefulness and entertaining value of the content.

The research findings contribute to the customer engagement dimension in the health-care sector and help the companies construct effective branded content leading towards higher customer engagement.

Purpose: Twenty-first-century leaders operate in an unpredictable and complex business environment. The COVID-19 pandemic highlighted the VUCA (volatility, uncertainty, complexity, and ambiguity) nature of the business milieu and proved to be a real-life test for organisations and their leaders. It brought challenges and losses at personal, organisational, societal, national, and global levels. Nevertheless, some leaders and organisations thrived during and after the pandemic. This research assimilates leadership lessons from extant literature and real-life cases of leadership successes and failures. The authors aim to consolidate leadership strategies valuable in unpredictable, demanding, and complex times like COVID-19.

Methodology: The research relies on an extant literature review and opinions of four c-suite leaders captured through semi-structured interviews. The study uses content analysis to analyse the primary data collected.

Findings: The present research presents its results as a VUCA Leader Toolkit. It consolidates learnings from real-life case studies, extant literature, business reports, and experts’ opinions. It addresses the gap in existing research on VUCA-suited leadership strategies. The outcome of the present study is a clear, adequate, explicit, and well-defined list of VUCA-necessitated leadership strategies.

Originality/value: The research proves its utility in providing the VUCA Leader Toolkit. The outcomes carry usefulness for both present and future business leaders. The business environment today is ever-changing, complex, and uncertain. This unpredictability, uncertainty, complexity, and fuzziness would proliferate in the coming times. Hence, it is imperative to have a list of leadership strategies that may serve as a ready reckoner for leaders.

White button (Agaricus bisporus) mushroom (WBM) is a good source of fiber, protein and unsaturated fatty acids and is considered an effective food for the treatment of hyperlipidemia.

Male Wistar strain rats (28) were divided into four groups, two control and two experimental, which were fed a semi-synthetic diet containing 1 per cent cholesterol and supplemented with 5 and 10 per cent dried mushroom for a period of 42 days. At the end of the experiment, the rats were anesthetized and blood samples were taken. The serum and liver were analyzed for total lipids, triglycerides and phospholipids.

Serum total lipid and triglyceride levels were reduced significantly in rats fed on 5 and 10 per cent WBM. However, serum phospholipid levels were decreased only in rats fed on 10 per cent WBM. The deposition of total lipids and triglycerides in liver decreased significantly in the experimental rats. However, no significant differences were observed in liver phospholipid levels in any experimental group of rats.

Hyperlipidemia is one of the leading medical problems nowadays, and it represents a major concern because of the associated death rates occurring in different communities. The study results indicate that this problem can be reduced through the consumption of A. bisporus mushrooms.

Organic food is getting attention these days from consumers and producers, in pursuit of safe and chemical-free food. In India, there is an upsurge in entrepreneurs in the organic food sector, with women entrepreneurs signalling higher numbers. Women entrepreneurs have the potential to contribute significantly to the field of organic food; the only requirement is to address the challenges faced by them. This paper aims to attempt at exploring and modelling the challenges faced by women entrepreneurs in the organic food sector.

Significant challenges were identified through literature review, primary data collection and expert opinions. The identified challenges were then modelled through total interpretive structural modelling and fuzzy-matriced impact cruises multiplication applique techniques to give a meaningful contextual relationship.

This study identified “poor government support” and “less awareness” amongst the stakeholders, as the most strategic challenges with the highest driving power to influence other challenges. In contrast, “low funding options” and “fewer buyers” emerged as the most dependent challenges for organic food women entrepreneurs in India.

The model proposed in the study gives a roadmap for different stakeholders in the food industry to scale up organic food women entrepreneurs in India.

Marketing.

This case is suitable for MBA/MS courses for students of services marketing; courses such as sustainable development of business and integrated marketing communications.

Cordlife Limited entered the Indian market for cord blood banking in 2006 and by 2011 held third place in market share. However, the management of Cordlife had identified a major problem as a lack of awareness of the potential of cord blood banking among the Indian middle class, and the lack of a proper infrastructure for transportation of biological packages. Cordlife undertook several marketing initiatives to spread awareness. Marketing such a sophisticated service like cord blood banking called for heavy investments. The case provides an opportunity to closely examine various marketing activities in detail and understand how problems associated with intangible services can be managed. In addition to marketing of services the case highlights the existence of several gaps in designing a delivery in a service. The scope of the case can also be extended to the concept of service pricing and also integrated services marketing communications.

The case is designed for class discussions and in understanding the following concepts: the service gaps model; service pricing; and integrated service marketing communications.

This paper aims to investigate dynamics of food consumption practices among poor families in a developing country to advance the Food Well-being (FWB) in Poverty framework.

The research design used semi-structured interviews with 25 women and constructivist grounded theory to explore food consumption practices of poor families in rural South India.

Poor families’ everyday interactions with food reveal the relational production of masculinities and femininities and the power hegemony that fixes men and women into an unequal status quo. Findings provides critical insights into familial arrangements in absolute poverty that are detrimental to the task of achieving FWB.

The explanatory potential of FWB in Poverty framework is limited to a gender (women) and a specific country context (India). Future research can contextualise the framework in other developing countries and different consumer segments.

The FWB in Poverty framework helps identify, challenge and transform cultural norms, social structures and gendered stereotypes that perpetuate power hegemonies in poverty. Policymakers can encourage men and boys to participate in family food work, as well as recognise and remunerate women and girls for their contribution to maintaining familial units.

This paper makes an original contribution to the relevant literature by identifying and addressing the absence of theoretical understanding of families, food consumption and poverty. By contextualising the FWB framework in absolute poverty, the paper generates novel understandings of fluidity and change in poor families and FWB.
