Abstract

Purpose

The purpose of the current article is to explore the rotational behavior on nanofluid flow over an exponentially stretching surface. Heat and mass flux are formulated upon Cattaneo–Christov theory.

Design/methodology/approach

Effect of thermophoretic, Brownian motion and thermally convective conditions is further retained. Novel boundary layer approximations are applied to transform the governing equations of continuity, momentum, energy and nanoparticle volume fraction. Convergent series solutions are obtained to manage the rotating flow with the aid of homotopy analysis method (HAM).

Findings

Depending on the several dimensionless parameters including the local rotation parameter the Prandtl number Pr, the thermophoresis parameter, the Brownian motion parameter, the Lewis number Le, Biot number Bi, Deborah number in terms of heat flux relaxation parameter and Deborah number in terms of mass flux relaxation parameter with the dimensionless physical quantities are deliberated through graphs. Present results are also likened with the foregoing results in significance.

Originality/value

No such assumptions have been made for the development of analytical solution so far.

Abstract

Purpose

The purpose of this paper is to investigate the effect of inclined magnetic field, variable viscosity and Cattaneo–Christov heat and mass flux theories on the steady MHD free convective boundary layer flow of viscous, incompressible and electrically conducting water-driven silver and titanium-oxide nanofluids over a vertical stretching sheet.

Design/methodology/approach

The boundary layer equations of momentum, energy and nanoparticle concentration are partial differential equations in nature, which are reduced to nonlinear ordinary differential equations by means of similarity transformations. The resulting nonlinear equations are solved analytically by means of optimal homotopy analysis method.

Findings

Assessments with numerical results are performed and are found to be in an excellent agreement. Numerical results of the skin friction factor, the local Nusselt number and the local Sherwood number are obtained through tables. The effects of various physical parameters on the velocity, temperature and nanoparticles fraction are incorporated through graphs. The study analyzes the efficiency of heat transfer of nanofluids in cooling plants and rubber sheets.

Originality/value

No research works have been conducted to evaluate the effects of various physical phenomena on the copper and titanium nanofluids flow.

Abstract

Purpose

The paper aims to investigate existing research in factors impacting organic food purchase with special reference to eco-labels and identify the relative influence of various determinants.

Design/methodology/approach

A conceptual framework is proposed of organic food buying behaviour after analysing a sample of 154,072 consumers reported in 91 research studies from 2001–2020. The factors are categorised into four categories on the basis of relatedness. In addition, the factors were analysed based on time, region and national economic status.

Findings

The impact of consumer psychographics, socio-demographic and product-related factor categories were found to be more pronounced compared to supply-related factor category. The results show that among individual factors like health concern, environment concern, knowledge and awareness, eco-labels and price followed by trust in organic food are the most important factors in organic food purchase. The findings suggest that eco-labels increase trust in organic food by reducing information asymmetry in consumers. However, there were differences in perception and factors importance between high-income economies and emerging economies.

Originality/value

The study is unique, as it analyses secondary research based on criteria of high-income economies and emerging economies. The conceptual framework can also be incorporated further into different cognitive models like the theory of planned behaviour.

Abstract

Purpose

This paper aims to investigate the determinants of organic food buying behaviour in an emerging economy like India, where organic food yet has low market share in spite of its potential. Using the theory of planned behaviour (TPB) as the underlying basis, it attempts to explain the effect of attitude, subjective norms and the perceived behaviour control (PBC) on buying intention towards organic food among respondents in Delhi-National capital region, India. Additionally, it attempts to discriminate functional and constructive attitudes.

Design/methodology/approach

A quantitative questionnaire survey approach was used on 306 respondents and multiple linear regression was used to validate the research model.

Findings

Attitudes and PBC have a significant positive impact on the intention to purchase organic food. This paper found subjective norms to be weak and barely significant to intention. The results conclude that health motives, past purchase behaviour, knowledge, affordability and trust in organic certification label are the main facilitators in organic food purchase. Primarily, the respondents see buying organic food regularly as being of value and enjoyable to them. A more favourable appearance vs conventional food was negatively related to behavioural intention.

Originality/value

This research could aid all stakeholders in the organic food sector, particularly emerging economies like India where the organic market is still nascent. It could be an essential driver to improve customer involvement and thus aid them in the decision-making process to choose organic food over conventional food. It also attempts to establish the usability of TPB in assessing functional attitudes based on constructive attitudes for organic food purchase.

Abstract

Purpose

Burgeoning challenges of climate change and poverty alleviation across many parts of the world have enforced the policy makers and researchers to develop an alternate system for performance assessment of an individual, a country, and a corporate. The purpose of this paper is to analyze the sustainability strategies of three leading states in the Indian leather industry – Tamil Nadu (TN), West Bengal (WB) and Uttar Pradesh (UP) – to gain insights into their efforts and progress in generating economic, social, and environmental values.

Design/methodology/approach

This study used case study approach for investigative analysis, and triangulation method – interviews and field visits, for data verification. The study examines the various sustainability strategies by applying economic value creation (evaluation of growth in total turnover, evaluation of the growth in profitability, evaluation of leverage), social value creation (evaluation of the growth in wages, evaluation of the growth in employee welfare expenses), and environmental value creation (conservation in raw material consumption, conservation in energy consumption, evaluation of waste management practices).

Findings

The findings reveal that the three states differ significantly from each other both in terms of efforts made and progress achieved during the period of study, 1998-2013. UP seems to be making the most consistent progress in achieving economic value, while WB shows the most progress in creating social value, and TN leads the pack in terms of creating environmental value. Thus, the three leading states in the Indian leather industry have been allowing trade-offs to get competitive advantage over others.

Research limitations/implications

The opaqueness with which the Indian leather Industry conducts social and environmental practices clearly limits the sources of accurate and reliable data, and the ability of researchers to precisely identify the problems and suggest solutions.

Practical implications

The opaqueness with which the Indian leather Industry conducts social and environmental practices clearly impacts the policy makers, practitioners, and researchers to continue such initiatives and improve the lives of people in India for whom continuing this profession is a big challenge and a hurdle to accomplish their livelihood.

Originality/value

The paper gives a theoretical explanation of the sustainability in the leather industry with respect to its strategies in terms of economic value, social value, and environmental value.

Abstract

Purpose

The purpose of this paper is to demonstrate the difference in firm performance between pollution prevention and pollution control strategies using a selected case study from the Indian leather industry.

Design/methodology/approach

This study followed a case study-based inductive research approach to validate the proposed preposition on field. The case-study analysis was based on qualitative and quantitative data. The authors developed a questionnaire and an interview protocol to capture the data about different industrial practices and motivation behind them. The study followed the concept of the triple bottom line approach for assessing the progress of the case firm on sustainability scale.

Findings

With the help of pollution preventive measures, such as replacement of salted skin with fresh skin and chromium salt with a phosphonium-based tanning agent, the case firm could overcome the biggest challenge of bringing down the level of total dissolved solid from 40,000 to 5,000 ppm in the raw effluent. Moreover, the firm has successfully recycled and converted tannery scraps and other waste into organic manure for internal use in its own plantations.

Research limitations/implications

The findings of this study could not be generalized as these are based on a single case study.

Originality/value

This study presents an example of sustainable practices and their benefits to the Indian leather industry to follow.

Abstract

Purpose

It is essential to track the development of resource and pollution intensive industries such as textile, leather, pharmaceutical, etc., under burgeoning pressure of environmental compliance. Therefore, the purpose of this paper is to analyze the progress of Indian leather industry in terms of individual factors and total factor productivity.

Design/methodology/approach

This study applies and examines the various concepts of productivity such as labor productivity, capital productivity, material productivity and energy productivity. Further, it assesses and compares the performance of Indian leather industry in Tamil Nadu (TN), West Bengal (WB) and Uttar Pradesh (UP) based on productivity analysis, spatial variations determinants in productivity and technology closeness ratio.

Findings

The findings suggest that as per the productivity analysis, WB leather clusters have performed remarkably better in terms of partial factor productivity and technical efficiency (TE), followed by TN and UP. This can be attributed to shifting of leather cluster of WB to a state-of art leather complex with many avenues for resource conservation. Further, the findings reveal that the firm size and partial factor productivities have significant positive correlation with TE which supports technological theory of the firm.

Practical implications

The results of this study can be useful for the policy makers associated with the Indian leather industry especially to design interventions to support capacity building at individual firm level as well as cluster level to enhance the efficiency and productivity of overall industry.

Social implications

The findings also support the resource dependence theory of firm according to which the larger size firms should reflect on resource conservation practices, for instance the concept of prevention is better than cure based upon 3R (reduce, recycle and reuse) principles.

Originality/value

The paper gives an explanation of the productivity in the leather industry in terms of its factor productivity and TE.
