Abstract

Shellac is one of the earliest materials used in protective and decorative coatings. This natural resin has properties not found in any other single natural or synthetic resin. It is particularly valued for the hardness, gloss and toughness of its films, and its excellent adhesion to a wide variety of surfaces such as wood, metal, paper, fabric etc. This versatile resin is still widely used for the varnishing and polishing of floors and furniture, leather paper, metal foil etc. A use developed recently for this resin is in the anti‐corrosive primers for steel and other ferrous metals.

Abstract

The curing of shellac with epoxy resin by fusion was studied in detail by Tripathi et al. An improvement in the film properties was noticed for the varnishes prepared from the cured products of 70 parts of shellac with 30 parts of epoxy resin. Similar study was made on the modification of shellac with phenolic resin by Kumar and Sankaranarayanan and Kumar. The films obtained from the modified varnishes showed improved heat and water resistance.

Abstract

Insulating varnishes are widely used for coating of armatures/coils of electric motors, transformers and also for finishing electrical components. Natural resin shellac finds considerable use in the manufacture of insulating varnishes. Improved dielectric properties have been obtained for varnishes prepared from shellac modified with synthetic resins, drying oils etc. The present article provides information about the researchers so far carried out on both the air‐drying and baking type of insulating varnishes based on shellac.

Abstract

Purpose

The purpose of this paper is to study the performance of generalized frequency division multiplexing (GFDM) in some frequency selective fading channels. The exact symbol error rate (SER) expressions in Hoyt (Nakagami-q) and Weibull-v fading channels are derived. A GFDM transceiver simulation test bed is provided to validate the obtained analytical expressions.

Design/methodology/approach

Modern cellular system demands higher data rates, very low-latency transmissions and sensors with ultra low-power consumption. Current cellular systems of the fourth generation (4G) are not able to meet these emerging demands of future mobile communication systems. To address this requirement, GFDM, a novel multi-carrier modulation technique is proposed to satisfy the future needs of fifth generation technology. GFDM is a block-based transmission method where pulse shaping is applied circularly to individual subcarriers. Unlike traditional orthogonal frequency division multiplexing, GFDM transmits multiple symbols per subcarrier. The authors have used the probability density function approach in solving the final analytical expressions.

Findings

Detailed analysis of GFDM performance under Hoyt-q, Weibull-v and Log-Normal Shadowing fading channels. Exact analytical formulae were derived which support the simulations carried out by authors and other authors. The exact dependence of SER on fading parameters and roll-off factor α in the raised cosine pulse shape filter was determined.

Practical implications

Development and fabrication of high-performance GFDM systems under fading channel conditions.

Originality/value

Theoretical support to simulated system performance.

Abstract

Purpose

The study aims to analyse the challenges faced by the Indian Handloom Sector with a special focus on the state of Uttar Pradesh before and during the COVID-19 pandemic. This study further explores the benefits of AatmaNirbhar Bharat Abhiyan for the betterment of the livelihood of the COVID-19–hit handloom weavers and allied workers.

Design/methodology/approach

A total of 400 handloom weavers and allied workers from ten cities of Uttar Pradesh were contacted through telephone. Descriptive statistics were applied to measure the awareness about the government welfare schemes and the benefits of these schemes. Furthermore, satisfaction and opinion of the handloom weavers and allied workers regarding the benefits and sufficiency of the funds received under these schemes have also been measured.

Findings

Based on the results, the least awareness has been noted about government welfare schemes. However, a small number of weavers and allied workers were found beneficiaries of the schemes. Additionally, the majority of the respondents were found dissatisfied with the benefits. The COVID-19 pandemic is an addendum to the plight of handloom weavers and allied workers. The measures of AatmaNirbhar Bharat Abhiyan could be used to aid weavers and allied workers to restore their lost revenue.

Research limitations/implications

This study has limitations. Firstly, the research is limited to the handloom industry of Uttar Pradesh. Future researchers could consider the handloom sector of other states like Maharashtra and Andhra Pradesh, known for hand-woven clothes. Secondly, this study aims to analyse the role of AatmaNirbhar Bharat Abhiyan in improving the living conditions of handloom weavers and allied workers and not to measure the impact of the Abhiyan on handloom weavers or the handloom sector. Researchers could measure the impact in future studies. Thirdly, the authors have not applied any behavioural theory or marketing models such as the Theory of Reasoned Action or the Blackwell model, which may be applied to study the attitude of handloom weavers towards welfare schemes. This may prove to be a potential direction for future research. Additionally, master weavers and handloom cooperatives societies were excluded while collecting the data. Future researchers could consider them to examine the role of the government’s welfare schemes for uplifting the socio-economic condition of the handloom weavers, allied workers, master weavers and the business of cooperative societies. Finally, due to lockdown and travel ban, the authors were forced to limit their survey to telephone only because of which they could not get the qualitative information in full. Researchers for future studies could visit the handloom concentrated areas personally or take the help of an enumerator for data collection.

Practical implications

The research holds significance for the young and competent designers, handloom weavers and allied workers. Designers could work with and hire handloom weavers of Uttar Pradesh. If designers and weavers work together, it will help them restore their business and generate revenue that they have lost due to the COVID-19 pandemic. Furthermore, policymakers can collaborate with designers, which will help enhance the socio-economic condition of handloom weavers and allied workers, which has deteriorated due to the COVID-19 crisis.

Originality/value

The research holds significance from the point of view of exploring the challenges faced by handloom weavers and allied workers of the state of UP before and during the COVID-19 period while examining the role of AatmaNirbhar Bharat Abhiyan in setting off these challenges.

Abstract

This article documents instances of racism that have previously acted as barriers to Indian students' academic success in Australia. It is felt that such incidents would not have happened to students from, for example, China or Japan, as their governments would have taken more serious steps against the Australian government. There is a feeling in India that the Indian government can be seen as weak. Against this background, the article looks at potential reasons for racially motivated attacks against Indians in Australia, and at what can be done to reduce these, as well as both the Australian and Indian government responses to the particular instances reported.

Abstract

International Education is worth billions of dollars to the world economy, and many countries such as the United States, United Kingdom, Canada and Australia have government initiatives that look to stimulate and guide international student mobility, research and technology transfer. The involvement of the state into student mobility does not come without risk. Government foreign policy and international relations between sending countries and English-speaking study destinations threatens to upset the historical norms of international mobility. What is more, world events such as the global pandemic of 2020, will have a profound impact on the future of international education, and may change the international landscape altogether. This chapter will frame the challenges facing institutions who benefit from international mobility in the context of geopolitics and world events. It will explore how institutions can leverage strategic enrolment management tactics to help mitigate enrolment risks posed by global disruption.

Abstract

Learning outcomes

The case focuses on the importance of the brand-building process, which takes place in B2B companies. Commodity companies focus a lot on the sales and distribution aspect of their marketing strategies but do not emphasize the importance of developing their brands. At the end of the discussion, the participants would be able: to examine the steps involved in conceptualizing the brand identity for an existing product in a highly competitive B2B market, as per Kapferer’s Brand Identity Matrix. To understand the steps involved in the journey of internal and external brand-building processes in B2B. To analyze the various challenges and issues faced by large organizations dealing in the metals and commodity business.

Case overview/synopsis

The case discusses a marketing challenge faced by Jindal Steel and Power Limited (JSPL) in launching a new brand of thermomechanical treatment (TMT) products in the market. Traditionally, the company had focused on the sales and distribution aspect of their marketing strategies but did not emphasize the importance of developing their brands. This case is based upon the challenges faced in the creation of a new brand identity for JSPL’s TMT products by the protagonist, Mr Paras Sharma (who is the brand custodian and manager in this case).

Abstract

Purpose

The purpose of this paper is to highlight the corporate and non-corporate leadership practices in India, the effect of culture on such practices and how these drive management philosophies.

Design/methodology/approach

Semi-structured interviews were conducted with CEOs from India. A key finding was that Indian leadership shares some aspects of global leadership traits, but factors such as culture and religion are significant influences on their leadership style and philosophy.

Findings

The findings are helpful to both practitioners and policy makers seeking to understand the leadership style of Indian CEOs.

Originality/value

Many qualities of a good leader, as defined by Indian CEOs were derived from the Hindu mythology (Bhagvad Gita, Mahabharata, Ramayana and the four Vedas).
