Abstract

Purpose

The purpose of this paper is to examine quadratic convergence of finite element analysis for hyperelastic material at finite strains via Abaqus‐UMAT as well as classification of the rates of convergence for iterative solutions in regular cases.

Design/methodology/approach

Different formulations for stiffness – Hessian form of the free energy functionals – are systematically given for getting the rate‐independent analytical tangent and the numerical tangent as well as rate‐dependent tangents using the objective Jaumann rate of Kirchoff stress tensor as used in Abaqus. The convergence rates for available element types in Abaqus are computed and compared for simple but significant nonlinear elastic problems, such as using the 8‐node linear brick (B‐bar) element – also with hybrid pressure formulation and with incompatible modes – further the 20‐node quadratic brick element with corresponding modifications as well as the 6‐node linear triangular prism element and 4‐node linear tetrahedral element with modifications.

Findings

By using the Jaumann rate of Kirchoff stress tensor for both, rate dependent and rate independent problems, quadratic or nearly quadratic convergence is achieved for most of the used elements using Abaqus‐UMAT interface. But in case of using rate independent analytical tangent for rate independent problems, even convergence at all is not assured for all elements and the considered problems.

Originality/value

First time the convergence properties of 3D finite elements available in Abaqus sre systematically treated for elastic material at finite strain via Abaqus‐UMAT.

Abstract

Purpose

The purpose of this paper is to examine the indirect effects of nutritional knowledge and attitude toward food label use on food label use through self-efficacy and trust, as well as whether gender moderates this relationship.

Design/methodology/approach

A sample of Indian adults with multiple chronic conditions was surveyed about their nutritional knowledge, attitude, self-efficacy and use of food labels. Hypotheses were tested using Hayes’s (2013) PROCESS macro for SPSS.

Findings

The results show that nutritional knowledge and attitude toward food label use positively predict food label use through self-efficacy and trust. However, these mediation effects are moderated by gender such that the indirect relationship is stronger among men than women.

Practical implications

Food marketers and government agencies engaged in nutrition education campaigns should aim to increase patients’ confidence in comprehending food label information.

Social implications

Since food labels can be a valuable tool to help patients with chronic diseases to make informed decisions about their diet and lifestyle, regulators may consider mandating nutritional labels on foods to help them improve their food or dietary choices.

Originality/value

This study uniquely applies Fisher and Fisher’s (1992) information–motivation–behavioral skills model as a theoretical framework to examine the influence of nutrition knowledge and attitude toward food label use on food label usage of Indian patients with multiple chronic diseases.

Abstract

Purpose

Recurrent pregnancy losses (RPL), a major contributor of reproductive wastage, affect maternal health both physically and mentally. Folate and B12 (Vitamin B12) deficiency anemia is common in the reproductive age group women in developing countries like India. And due to proven role of folate in various maternal and fetal anomalies, women are routinely prescribed folic acid under various national policies. However, B12 supplementation is rare, despite known deleterious effects of its deficiency. The purpose of this paper is to understand RPL through anemia with special reference to folate and B12 imbalance.

Design/methodology/approach

Multiparous women with normal obstetric outcomes (n=135) and women with Idiopathic RPL (n=105) were recruited in the study. All women were non-pregnant and belonged to North Indian population. Hb, serum folate and B12 and plasma homocysteine were measured in all the women. Anemia was classified according to WHO guidelines (Hemoglobin (Hb)<12g/dL).

Findings

The incidence of Anemia was more among normal multiparous women (73 percent) as compared to women with RPL (60 percent). However, unlike folate deficiency anemia among controls, B12 deficiency anemia was observed in women with RPL. Moreover, these women, despite being less anemic, with high B12 deficiency and folate sufficiency (presumably due to folate supplementation) had more imbalanced vitamin metabolism, as evident from homocysteine levels. The study suggests that anemic or non-anemic deficiencies of B12 and folate among women with RPL may be combated by screening for both vitamins, rather than supplementing folate indiscriminately to all.

Research limitations/implications

One of the limitations is that ferritin levels for iron deficiency anemia could not be measured in this study.

Originality/value

The present study is the first study, to the best of our knowledge, where we looked for the role of imbalance of folate and B12 in women with RPL.

Abstract

India is a country of socio-cultural diversity. Every society and culture existing in India is full of values, ethics and morality regarding good deeds. The exhaustive survey of corporate social responsibility (CSR) literatures from Indian philosophical perspectives observes many studies based on the socio-cultural and religious aspects. It has been observed all these philosophical views and concepts covering socio-cultural and religious backgrounds have received attention in the field of CSR. It is observed that almost all views have been fully explored in the context of CSR. Therefore this chapter tries to detect the drivers of CSR with all these philosophies prevalent in the culture of Indian society. This study utilises the hermeneutics, a qualitative research methodology which involves an in-depth study, critical analysis, thoughtful understanding and explanatory interpretation of the concepts of CSR originated from diversified Indian society and culture. In a nutshell, from these viewpoints and philosophies of different cultures, CSR is seen from an inside-out perspective.

Abstract

Risk factors for population relocation as a result of severe catastrophes are increasing on a global scale. The frequency of catastrophic weather events is rising, infrastructure is getting older, the population is expanding, and urbanization is increasing. This study explores the influencing factors of livelihood, vulnerability, and livelihood resilience of climate-induced displaced people in developing countries, particularly in South Asia. A mixed-method approach comprising a systematic review and a narrative review has been applied in this study. A systematic review guided by PRISMA has been used to identify the relevant documents and the extracted information has been described through a narrative review approach. This study reveals that climate-induced displaced people are generally vulnerable to maintaining their livelihood, but there are a few exceptional cases where displaced people could diversify their livelihood strategies. The major influencing factors of their livelihoods are riverbank erosion, loss of assets and properties, food insecurity, seasonal hunger, low access to finance, and low job opportunity. This study argues that climate-displaced people have a long struggle to enhance their livelihood resilience, but it is a challenging task for them, particularly at the household level. The major influencing indicators under adaptive, absorptive, and transformative capacities of livelihood resilience are income and food access, agricultural and non-agricultural assets, sensitivity, climate variability and hazards, basic services, social safety nets, and institutional participation. Appropriate governance in the structural and non-structural transformation of livelihood capitals can enhance the livelihood resilience of climate-induced displaced households. In the case of Bangladesh, the coastal and Riverine Island communities are the key victims of climate-induced hazards, so they migrated frequently to reduce their vulnerability and enhance livelihood resilience. The study recommends ensuring transparency and accountability, proper coordination among stakeholders for promoting the resettlement, disaster-resilient housing and infrastructure, and Khas land (government-owned land) to the displaced people can enhance their livelihood resilience.

Abstract

Purpose

It is seen that little amount of work on optimization of mechanical properties taking into consideration the combined effect of design variables such as stacking angle, stacking sequence, different resins and thickness of composite laminates has been carried out. The focus of this research work is on the optimization of the design variables like stacking angle, stacking sequence, different resins and thickness of composite laminates which affect the mechanical properties of hybrid composites. For this purpose, the Taguchi technique and the method of gray relational analysis (GRA) are used to identify the optimum combination of design variables. In this case, the effect of the abovementioned design variables, particularly of the newly developed resin (NDR) on mechanical properties of hybrid composites has been investigated.

Design/methodology/approach

The Taguchi method is used for design of experiments and with gray relational grade (GRG) approach, the optimization is done.

Findings

From the experimental analysis and optimization study, it was seen that the NDR gives excellent bonding strength of fibers resulting in enhanced mechanical properties of hybrid composite laminates. With the GRA method, the initial setting (A3B2C4D2) was having GRG 0.866. It was increased by using a new optimum combination (A2B2C4D1) to 0.878. It means that there is an increment in the grade by 1.366%. Therefore, using the GRA approach of analysis, design variables have been successfully optimized to achieve enhanced mechanical properties of hybrid composite laminates.

Originality/value

This is an original research work.

Abstract

Purpose

COVID-19 pandemic is a global health emergency which posed new challenges to the organizations to adjust their ways of working by redefining approach to work culture. The objective of this paper is to study as to how COVID-19 has impacted organizational culture which can be sustained with good leadership style. The aim of the paper is to identify and analyze the change in organizational culture and leadership style flexibility adoption required during the pandemic.

Design/methodology/approach

This paper is based on qualitative research that focused on newspaper articles. In the paper, the authors made analysis of newspaper articles on NVIVO software published on culture and leadership from February to December 2021.

Findings

Three main themes that emerged across the study include the change in leadership perspective, organizational perspective and employee perspective to reshape the organizational culture. Companies that support on flexible working hours, work from home and virtual gatherings are likely to attract and retain the most talented employees.

Practical implications

The study gave useful insights to establish well-developed standard operating practices to manage the cultural change. The organizations which reinforce their leadership style to provide psychological support to its employees and amend the policies thereof, can best respond to the potentially damaging effects of COVID-19 to enhance the job satisfaction of its people.

Originality/value

The paper is among the very few studies that examined as how to sustain a good culture in an organization during tough times and how a leader should manage the entire team with the help of qualitative analysis through analysis of newspaper articles. The specific contribution of this paper is to align organizational culture with leadership based on democratic values and standards of legitimacy during tough times so that focus can be made on well-being of employees, strong work ethics and thereby increasing work commitment of the employees.

Abstract

Computer usage has become commonplace and there has been an increasing number of local efforts in organising indigenous information for individual and institutional utility. Access to information online or in CD‐ROM media is now just a matter of money; at the same time access to indigenous information has remained a challenging effort both for the user and the infomediary. Information services/products of all kinds are being generated by various agencies in the government, public and private sectors and are emerging out into the Indian information marketplace. There are a number of abstracting journals, which, in a natural process of migration, are now available in dual formats – print as well as machine readable. Besides bibliographic information, service providers are generating factual information – as directories of all descriptions, financial and commercial data, full texts of case laws, export‐import policy and so on. In this paper an attempt is made to present an overview of some of the important electronic databases developed in India or on Indian topics.

Abstract

Purpose

This paper investigates the mediating role of access to finance and entrepreneurial education for small and marginal farmers (SMFs) in the Indian northern state of Punjab. Furthermore, it examines the inter-mediatory role of entrepreneurs and the access to finance in the promotion of innovation, development and consequently poverty alleviation.

Design/methodology/approach

To gain a deeper insight, we used a purposive sampling technique, involving in-depth, face-to-face interviews based on a semi-structured questionnaire amongst 185 farmers from the state of the Punjab in India. The combination of open ended and dichotomous questions amenable to the Likert scale, captured responses and the transcribed questionnaires were thematically analysed.

Findings

Using the analysis of the quantitative and qualitative responses, we explain the cause and consequences of the finance gap and the impact of poverty on household income and the debt levels of SMFs. The findings suggest that the expanding pool of SMFs is due to land ownership fragmentation that disenfranchises SMFs from accessing adequate finance thus limiting their ability to adapt to technological innovations, and therefore limiting their productivity and growth. This essentially limits their ability to transform their economic and social wellbeing. The findings from the data analysis suggest a lack of access to finance negatively impacts on SMFs' ability to use innovative practices, technologies and productivity. This adversely affects income level, access to education and social goods to propel them out of poverty. The findings advocate that government policy should focus on land reforms, which provide adequate access to finance to enable the adaption of technology and an access to markets to empower marginal farmers.

Research limitations/implications

Land fragmentation resulting with population growth in emerging economies continuously expands SMFs. To improve efficiency, productivity and entrepreneurial traits amongst SMFs, it is a pre-requisite to have an agile economy. However, in emerging economies such as India, the responses of 185 farmers suggest, a bespoke policy to promote the interest of SMFs through enabling them access to finance, technologies, training and education, continues to prove elusive. This novel empirical research provides evidence that demands that policymakers, commercial institutions and donors need to respond to the needs of SMFs to ensure food security and an optimal utilisation of farmland. The limitation of this research is that the sample is from one country, which limits its generalisation. The findings of this study could be enhanced by conducting comparative studies in other regions or economies.

Originality/value

This empirical study examined the barriers to enterprise for SMFs in the Indian Punjab; it examined the causes and consequences and the implications for food security for India. The findings of this study highlight the importance of developing the entrepreneurial capabilities of SMFs through effective education, training and above all through an adequate access to finance to enable them to adapt their technology. Furthermore, the findings make a case as to why SMFs are an integral part of the food chain and why it is necessary to enhance their efficiency, productivity and their access to finance.
