The purpose of this study is to outline a conceptual framework for customer engagement in the context of social media for emerging markets. Three competing models of customer engagement were identified and tested to arrive at the best suited model for the given contexts. The alternative conceptual frameworks involve the constructs of active participation, community trust and community commitment in relation to customer engagement.

Data were collected using questionnaires sent via e-mail to respondents. Structural equation modelling was then used to arrive at the best suited model, while also empirically testing for the relationships among the constructs.

The study, by way of an empirical comparison of alternative conceptual frameworks, presents a customer engagement framework best suiting the social media context for emerging markets. The study also outlines active participation, community trust and community commitment to be acting as antecedents to customer engagement. Further active participation is identified as a necessary antecedent to customer engagement based on the comparative assessment of the frameworks.

While there is not much consensus on the nature of customer engagement, the study offers insights to marketers in terms of managing customer engagement with their brand communities. The study identifies the role and importance of inducing active participation in a brand community context. Further, it also identifies community trust and community commitment to be occurring as antecedents to customer engagement, with commitment implying for a more pronounced role in the framework.

There is no consensus among researchers regarding the nomological network surrounding customer engagement. Further, very few of these studies have focussed on this construct in the context of emerging markets. This study thus attempts to close the above gap, by testing for alternative conceptual frameworks involving customer engagement, in the context of social media for emerging markets.

Religion plays a crucial role as a sociocultural factor to assess consumer behavior. Stemming from the above, this study aims to analyze the impact of religion and ethnic concern on the purchase intention (PI) of consumers based on the theory of planned behavior.

The research method adopted for this study includes a meta-analysis of the extant literature for the past 20 years focusing on the relationship between religiosity and PI. Data of 24 values from 23 studies were used to assess the impact of religiosity on the PI of consumers.

The findings of this study indicate that religiosity has a strong impact on the PI of consumers. Further, this study identifies that location, sample size and product category play a vital role as moderators toward the relationship between religiosity and PI. This study identifies critical and pertinent implications for brands as they reach out to religious and cultural groups across various geographies, in the context of identifying target markets and adapting marketing strategies.

This study acts in response to the consistent call for research to focus on religion-related variables and fills the gap calling for empirical research into religiosity and its impact on PIs. This study makes notable theoretical, managerial and methodological contributions to the field.

The paper aims to examine the effects of floods on economic growth in India from 1980 to 2019, taking into account the role of foreign direct investment (FDI) inflows and foreign aid.

The study uses augmented Dickey–Fuller (ADF) and Phillip–Perron (PP) tests to determine the stationarity of the variables. Several models, including autoregressive distributed lag (ARDL), fully modified ordinary least square (FMOLS), dynamic ordinary least square (DOLS) and canonical cointegration regression (CCR), are used to examine the impact of floods on economic growth.

The bounds test determines the long-term relationship between floods, FDI inflows, economic growth and foreign aid. According to the ARDL and FMOLS models, floods have a negative long-term and short-term impact on India’s economic growth. Furthermore, FDI inflows and foreign aid are beneficial to economic growth. The findings of the ARDL and FMOLS models are confirmed by the DOLS and CCR models. Granger causality establishes a unidirectional causality that extends from floods to economic growth. Further diagnostic tests show that the estimates are free of heteroskedasticity, serial correlation and parameter instability.

Indian government needs to invest more in research and development on flood management techniques. Institutional strengthening is also required to implement pre- and post-flood prevention measures properly. Sound disaster financing strategy and proper water bodies management should be prioritised. Foreign investment opportunities should be encouraged by strengthening international relations.

This is the first time-series study that analysed the effects of floods on economic growth in India. Moreover, the paper contributes to floods literature by applying several econometric models for robustness check.

A school canteen can serve as an important setting for nutrition and health promotion. The purpose of this paper is to describe secondary school students’ perceptions of Indian school canteens.

Convenience sampling informed the recruitment of 1,026 year 9 students from nine private schools in Kolkata, India, and data were collected through self-completion of paper-based questionnaires. Frequencies and χ² analyses were computed.

The school children reported that energy-dense, nutrient-poor foods like French fries (90.4 per cent), pizza (79.5 per cent) and cakes (69.2 per cent) were frequently available in the school canteens. However, only a few students (10.2 per cent) acknowledged the availability of nutritious foods like fruits. Only a small proportion of students were content with the nutritional quality of food supplied in the canteens (3.6 per cent), the cost of food (8.7 per cent) and availability of fresh foods like fruits (5.5 per cent). The provision of healthy foods in the school canteen was supported by two-thirds of the respondents (65.9 per cent); however, only a small proportion (18.3 per cent) supported the restriction of fried foods in school canteens.

These findings underscore the need for the design and implementation of healthy school canteen policies to foster healthy eating habits among Indian adolescents.

This is the first cross-sectional survey to investigate the views of adolescents regarding school food services in the Indian context.

This study aims to examine the psycho-emotional and social experiences of caregivers of children with autism spectrum disorder. Various facets of the caregiving experience are explored, including the feelings and thoughts of the parents/caregivers, such as the resilience experienced in their journey, how they coped with the challenges and also their positive experiences.

In this study, these aspects of the caregiving experience are broadly probed using semi-structured interviews subjected to narrative analysis. Lastly, there is a focus on the role of therapist-led intervention, specifically, the Eye to I^© intervention model and its contributions to the parent/caregiver experience.

Findings from this study indicate that parents benefit from interventions that bridge gaps in skills and interpersonal communication which parents/caregivers feel they encounter in their day-to-day activities. Additionally, support groups for parents and caregivers could further address these issues.

This exploration reveals insights about the roles of societal structures and the caregiving journey.

The investigation of fluid flow over a rotating disk has been increasing due to the spread of machine technology. Because of this development, we scrutinized the Magnetohydrodynamic (MHD) flow of hybrid nanofluid caused by a decelerating rotating disk with Ohmic heating, Soret and Dufour effects. The disk's angular velocity is taken to be an inversely time-dependent linear function. Moreover, the temperature-dependent viscosity of hybrid nanofluid is incorporated in the present investigation. Methanol is considered as base fluid, while copper oxide (CuO) and magnesium oxide (MgO) are nanoparticles.

Estimated fundamental partial differential equations of flow problems are altered as a dimensionless system of ordinary differential equations using appropriate similarity transformation and solved using a numerical technique: BVP Midrich scheme in Maple software. The impression of emerging non-dimensional parameters is portrayed graphically. All outcomes are shown in the velocity, temperature and concentration profiles.

The developed flow problem involves a non-dimensional parameter (A) that reveals the deceleration of the disk. For larger values of A, the disk decelerates faster and for some fixed time, the fluid surrounding the disk revolves more rapidly than the disk itself. The radial velocity of fluid diminishes and axial velocity becomes uniform when the disk is subjected to wall suction velocity (B).

This analysis is significant in biomedical engineering, cancer therapeutic, manufacturing industries and nano-drug suspension in pharmaceuticals. The novelty of the current study is the hybrid nanofluid flow with Ohmic heating, Soret and Dufour effects on a decelerating rotating disk. To the best of the author's knowledge, no such consideration has been published in the literature.

In this paper the effects of viscous dissipation and ohmic heating on the fluid flow and resulting heat and mass transfer caused by vertically moving rotating disk are explored with magnetic field acting perpendicular to disk rotation. The flow regime is also under the influence of Dufour and Soret effects.

An approach of similarity transformation is used to transform the governing set of equations into non-linear ordinary differential equations. Numerical simulations are carried out in Maple software to study the influence of incorporated non-dimensional parameters viz. disk movement parameter (−0.3 < S < 0.2), magnetic parameter (0.1 < M < 0.4), Eckert number (0.1 < Ec < 1), Schmidt number (0.1 < Sc < 1), Soret parameter (0.1 < Sr < 1) and Dufour number (0.1 < Du < 1) on velocity, temperature and concentration profiles.

The upward/downward motion of the disk along with rotation set up a three-dimensional flow over the disk surface and exerts the same effects as injection/suction through the wall. It is also observed that incorporated parameters along with disk movement greatly affect the flow regime and associated heat and mass transfer.

The present study examines the heat and mass transfer characteristics of incompressible Newtonian fluid over an impermeable rotating disk moving vertically. The effect of viscous dissipation and ohmic heating is considered. To the best of the authors’ knowledge, such consideration is yet to be published in the literature.

Additive manufacturing (AM) is expected to significantly transform the operations in manufacturing sector. It is also proposed to have optimistic applications in the medical supply chains (SC). However, its adoption in medical sector is faced with a range of barriers. Motivated by the need to establish an AM-based medical SC in a developing economy, the present paper analyses the potential barriers that would hinder the adoption of AM in medical SC.

Based on an extensive literature review and expert discussions, 12 significant barriers have been identified, which are analysed using an integrated interpretive structural modelling–analytical network process (ISM–ANP) methodology. An interrelationship between these barriers using ISM has been analysed to determine the driving-dependence power of these barriers using MICMAC (Matrice d' Impacts Croises-Multiplication Applique' e a' Classement) analysis. The barriers are then ranked using the ANP approach.

It has been focussed that the non-availability of a variety of materials, lack of education and training to designers and workers and production technology limitation are the most critical barriers. The results suggest that the managers should give greater significance to the technological and organizational barriers.

An approach to overcome these barriers can help the managers and organizations to develop successful AM-based SCs. The study is the first to identify and analyse the barriers for successful adoption of AM in medical SC context.
