In pursuit of affordable and nutrient-rich food alternatives, the symbiotic culture of bacteria and yeast (SCOBY) emerged as a selected food ink for 3D printing. The purpose of this paper is to harness SCOBY’s potential to create cost-effective and nourishing food options using the innovative technique of 3D printing.

This work presents a comparative analysis of the printability of SCOBY with blends of wheat flour, with a focus on the optimization of process variables such as printing composition, nozzle height, nozzle diameter, printing speed, extrusion motor speed and extrusion rate. Extensive research was carried out to explore the diverse physical, mechanical and rheological properties of food ink.

Among the ratios tested, SCOBY, with SCOBY:wheat flour ratio at 1:0.33 exhibited the highest precision and layer definition when 3D printed at 50 and 60 mm/s printing speeds, 180 rpm motor speed and 0.8 mm nozzle with a 0.005 cm³/s extrusion rate, with minimum alteration in colour.

Food layered manufacturing (FLM) is a novel concept that uses a specialized printer to fabricate edible objects by layering edible materials, such as chocolate, confectionaries and pureed fruits and vegetables. FLM is a disruptive technology that enables the creation of personalized and texture-tailored foods, incorporating desired nutritional values and food quality, using a variety of ingredients and additions. This research highlights the potential of SCOBY as a viable material for 3D food printing applications.

Entering a new era of digital transformation, Industry 4.0 (I 4.0) promises to revolutionize the way business has been done, providing unprecedented opportunities and challenges. This study aims to investigate empirically and comparatively analyse the benefits, challenges and critical success factors (CSFs) of Industry 4.0 across four continents and developing and developed economies.

This study used an online survey to explore the benefits, challenges and CSFs of developed and developing economies. In order to ensure the validity of the survey, a pilot test was conducted with 10 respondents. A total of 149 participants with senior managerial, vice-presidential and directorial positions from developed and developing economies spanning four continents were invited to take part in the survey.

The study ranks benefits, challenges and CSFs across economies and continents. Further, the benefit of Industry 4.0 helping to achieve organizational efficiency and agility differed across the developing and developed economies. Furthermore, the benefit improves customer satisfaction significantly differed across continents; in terms of challenges, Employee resistance to change had a higher proportion in developing economies. The future viability of I 4.0 also differed across the continents. Regarding CSFs, there was no difference across the developing and developed economies. Finally, change management and project management vary across the continents.

This study contributes to a balanced understanding of I 4.0 by providing empirical evidence for comparative analysis. Moreover, it extends the concept of resource dependence theory to explain how organizations in developing economies and developed economies deploy resources to manage external condition uncertainties to implement I 4.0. Furthermore, this study provides a structural framework to understand the specific benefits, challenges and CSFs of implementing I 4.0, which can be utilized by policymakers to promote I 4.0 in their economies or continents.

To the best of the authors’ knowledge, no studies have empirically demonstrated the comparative analysis of benefits, challenges and CSFs across economies and continents and distinguish an original contribution of this work.

Marketing strategy, strategic innovation.

Strategic brand management or marketing strategy courses at MBA level.

It seemed likely that a company with the highest number of product variants would consider product innovation to be its key source of sustenance in a crowded marketplace. Especially so, when the local and global competition was hotting up to a new launch every week. In the case of Micromax, a mobile handset maker from India tried to drive home the point that sustainability in emerging markets did not lie in inventing a new technology like Apple or Nokia or Sony did, albeit accompanied with a premium price tag. For the emerging markets, it was important to optimize the offering for the consumers. Strategic optimization could result from bridging the gaps in performance, infrastructure and organization design, which came naturally to this marketing-savvy mobile maker. Any company could make a cost-effective phone, but few could position, brand and sell it the way Micromax did. Shubhodip Pal, Head of Marketing at Micromax Informatics Pvt Ltd, India, pondered the marketing strategy which could pave the way into maintaining the company's national leadership position while creating a roadmap for its global foray. For Micromax, marketing strategy innovation, and not product innovation, would fulfil the goal of long-term growth in India and overseas markets.

The students studying this case are expected to learn: marketing strategy in emerging markets such as India, marketing strategy as the critical success factor for upcoming Indian companies rather than product innovation and doing business in emerging markets.

Micromax is an Indian consumer electronics company which began by selling mobile phones. In early 2014, Micromax ranked third in the mobile handsets category in India, behind Nokia and Samsung. The case is set in 2014, a watershed year for Micromax. It has to make decisions related to the future direction of the company. There are various options available, such as expanding into other consumer electronics and consumer durables categories, expanding outside India, etc. Micromax had recently introduced premium smartphones, and there had been a gradual shift in its target segment from rural to more upmarket consumers. Micromax aspired to be considered among the best brands in the world; however, the company was unsure of how to move forward. Its leadership had to decide on the right positioning for Micromax.

After completion of the case study, the students will be able to understand the different risks associated with a business, focusing on price risk and the importance of price risk management in business; understand and evaluate the products available for hedging price risk through exchange-traded derivatives in the Indian scenario; and understand and evaluate the different strategies for price risk management through exchange-traded derivatives in the Indian scenario.

The case study pertains to a small business, M/s Sethi Jewellers. The enterprise is being run by Shri Charan Jeet Sethi and his son Tejinder Sethi. The business is located in Jain Bazar, Jammu, UT, in Northern India. The business was started in 1972 by Charan Jeet’s father. They deal in a wide range of jewelry products and are well-established jewelers known for selling quality ornaments. Tejinder (MBA in marketing) was instrumental in revamping his business recently. Under his leadership, the business has experienced rapid transformation. The business has grown from a one-room shop fully managed by Tejinder’s grandfather to a multistory showroom with several artisans, sales staff and security persons. Through his e-store, Tejinder has a bulk order from a client where the client requires him to accept the order with a small token at the current price and deliver the final product three months from now. Tejinder is in a dilemma about accepting or rejecting the large order. Second, if he accepts, should he buy the entire gold now or wait to buy it later at a lower price? He is also considering hedging the price risk through exchange-traded derivatives. However, he is not entirely sure, as he has a few apprehensions regarding the same, and he is also not fully aware of the process and the instruments he has to use for hedging the price risk on the exchange.

The case study is aimed to cater to undergraduate, postgraduate and MBA students in the field of finance. This case study can be used for students interested in commodity derivatives, risk management and market microstructure.

The learning outcomes of this study are as follows:▪ to analyze service attributes that influence customers’ decisions to purchase services;▪ to identify the factors that influence customers’ perceptions of service quality;▪ to identify the “moments of truth” that the service provider (IndiGo) would need to monitor and manage through the service encounter; and▪ to use the Servuction model to analyze the various elements of the service process.

In May 2022, the chief executive officer of IndiGo Airlines - India’s largest passenger airline by market share, Ronojoy Dutta, faced flak over the airline staff's handling of a specially abled child travelling with his parents on IndiGo Airlines. The staff member, reacting to the tantrums of the disturbed child, had refused to allow the boy and his parents to board the flight. He had cited the “risk to other passengers” from the boy as the reason for such a refusal (Biswas, 2022). In spite of the boy’s parents being supported by their fellow passengers, the IndiGo staff member refused to relent, and the flight took off without the trio (Firstpost, 2022). The incident goes viral when a fellow flyer shares a Facebook post describing it first-hand and provokes widespread condemnation of the nation's “preferred airline” (IndiGo, 2023) by citizens and politicians on various social media platforms besides Facebook (Gupta, 2022). Dutta initially supports his employee even as he issues a statement expressing his regret at the “unfortunate incident” (Business Standard, 2022a). The regulatory body for aviation in India, the Directorate General of Civil Aviation, imposes a fine of INR 5 lakh on IndiGo for denying boarding to a specially abled child (Indian Express, 2022). How could an incident like this impact the perception of IndiGo’s service quality? How could Dutta better ensure that IndiGo managed the various touch points with the customer over the entire service encounter – the “moments of truth”? How could he prevent such a fiasco in the future, ensuring that IndiGo remains India’s “preferred airline”?

This case is intended to be taught in an undergraduate or MBA marketing course in a module on service marketing. The case can also form a 90-min module in a service marketing course within an advanced management or executive education program.

Food supply chain transparency and traceability is very important to address the issue regarding quality and safety. In traditional tracing system, with increasing the complexity of supply chain making product recalls difficult to manage and putting human lives at risk. To eliminate such types of risks, blockchain technology gives more efficient and reliable system for food tracing. Recently, there is an exponential rise in adoption of blockchain technology and most disparate IOT (Internet of things) devices in agriculture and food supply chain. It is an evolving technology that comforts the food supply chains by providing transparent data records and manage the food movement in the chain using distributed (P2P) network. That is more secured and there's no need for third party verifications. Our focus in this research will be on the Indian wheat supply chain and issues related to food losses caused by a lack of transparency and traceability. In order to improve the transparency of the wheat supply chain, we created an end-to-end smart wheat supply chain solution that combines blockchain technology, NFC tags, IoTs, and smart contracts. The solution is supported by entity relationship diagrams, information and money flow sequence diagrams, and a blockchain network diagram. We also used a security algorithm and the “NFC-Tag writer by NXP” program to validate and assess our system. This work could serve as a springboard for more in-depth research in this area. Depending on the existing situation in the industry, this research can also advise corporate procedures to deploy blockchain-based applications in the supply chain and logistics industry.

The study aims to analyze factors impacting firms’ success and persistence in a digital platform competition using the structure-conduct-performance (SCP) framework. The study also includes real-life cases that are beneficial to academicians and practitioners to understand and develop strategies for success and persistence during uncertainty.

A literature review to identify the factors that impact success and persistence in a digital platform competition was conducted following Webster and Watson (2002). Findings were integrated into a SCP framework to examine and understand the identified factors’ relational impact.

While analyzing factors under the SCP framework, all factors were divided into three categories: those impacting positively, those impacting negatively and those with ambiguous impact on the success and persistence in digital platform competition. Digital platform firms can exploit the positively impacting factors to increase market share by being distinctive from other digital platform firms and becoming dominant by withstanding competition. On the other hand, negatively impacting factors increase barriers to entry, intensify competition and reduce the distinctiveness of digital platform firms. Lastly, a few factors may have either a positive or a negative impact depending upon the particular characteristics of the firm/industry.

The study opens the scope for future research on empirically testing the developed conceptual framework and relationships by developing propositions to posit the possible impact of these factors on digital platforms’ success and persistence.

The study contributed to the existing literature by using SCP framework to analyze the factors affecting firm’s success and persistence in a digital platform competition. Also, the study has discussed the relational impact of factors rather than their impact in isolation.
