The purpose is to present a new approach for studying the phenomenon of traveling bubble cavitation.

A flow around a rigid, 2D hydrofoil (NACA‐0012) with a smooth surface is analyzed computationally. The Rayleigh‐Plesset equation is numerically integrated to simulate the growth and collapse of a cavitation bubble moving in a varying pressure field. The analysis is performed for both incompressible and compressible fluid cases. Considering the initial bubble radius as a uniformly distributed random variable, the probability density function of the maximum collapse pressure is determined.

The significance of the liquid compressibility during bubble collapse is illustrated. Furthermore, it is shown that the initial size of the bubble has a significant effect on the maximum pressure generated during the bubble collapse. The maximum local pressure developed during cavitation bubble collapse is of the order of 10⁴ atm.

A single bubble model that does not account for the effect of neighboring bubbles is used in this analysis. A spherical bubble is assumed.

A new approach has been developed to simulate traveling bubble cavitation by interfacing a CFD solver for simulating a flow with a program simulating the growth and collapse of the bubble. Probabilistic analysis of the local pressure due to bubble collapse has been performed.

This paper aims to review the healthcare supply chain (HSC) literature along various areas and to find out the gap in it.

In total, 143 research papers were reviewed during 1996-2017. A critical review was carried out in various dimensions such as research methodologies/data collection method (empirical, case study and literature review) and inquiry mode of research methodology (qualitative, quantitative and mixed), country-specific, targeted area, research aim and year of publication.

Supply chain (SC) operations, performance measurement, inventory management, lean and agile operation, and use of information technology were well studied and analyzed, however, employee and customer training, tracking and visibility of medicines, cold chain management, human resource practices, risk management and waste management are felt to be important areas but not much attention were made in this direction.

Mainly drug and vaccine SC were considered in current study of HSC while SC along healthcare equipment and machine, hospitality and drug manufacturing related papers were excluded in this study.

This literature review has recognized and analyzed various issues relevant to HSC and shows the direction for future research to develop an efficient and effective HSC.

The insight of various aspects of HSC was explored in general for better and deeper understanding of it for designing of an efficient and competent HSC. The outcomes of the study may form a basis to decide direction of future research.

This paper aims to introduce subjective dimensions of appraising visual servicescape aesthetics and to empirically test their influence on the consumer’s affective responses and preference, thus providing a holistic model to evaluate visual servicescape aesthetics from consumer’s viewpoint. It also tests the moderating role of service contexts in the modelled relationships.

Data was collected from 350 respondents using a laboratory-like experimental design, with one-shot treatment using photographic surrogates of services capes in four different service contexts.

Results indicate the visual servicescape aesthetics dimensions significantly and positively influence consumers’ affective states of arousal and pleasure. Also, service context moderates the relationship between servicescape aesthetics and affective responses.

As the subjective dimensions of visual servicescape aesthetics are borrowed from environmental psychology and introduced in marketing literature, it is likely to trigger a stream of research in service marketing domain.

Findings provide marketing practitioners insights into servicescape design, evaluation and selection decisions to improve return on such investments.

The study contributes to theory by introducing more appropriate holistic servicescape aesthetics variables borrowed from environment psychology and empirically establishing relationships between them, consumers’ affective responses and preference to the servicescape.

The fractional order HIV model has an important role in biological science. To study the HIV model in a better way, the model is presented with the help of Atangana- Baleanu operator which is in Caputo sense. Also, the characteristics of the solutions are described briefly with the help of the advance numerical techniques for the different values of fractional order derivatives. This paper aims to discuss the aforementioned objectives.

In this work, Adams-Bashforth method and Euler method are used to get the solution of the HIV model. These are the important numerical methods. The comparison results also are described with the physical meaning of the solutions of the model.

HIV model is analyzed under the view of fractional and AB derivative in Atangana-Baleanu-Caputo sense. The uniqueness of the solution is proved by using Banach Fixed point. The solution is derived with the help of Sumudu transform. Further, the authors employed fractional Adam-Bashforth method and Euler method to enumerate numerical results. The authors have used several values of fractional orders to present the outcomes graphically. The above calculations have been done with the help of MATLAB (R2016a). The numerical scheme used in the proposed study is valid and fruitful, and the same can be used to explore other real issues.

This investigation can be done for the real data sets.

In this work, HIV model is developed with the help of Atangana- Baleanu operator in Caputo sense. By using Banach Fixed point, the authors proved that the solution is unique. Also, the solution is presented with the help of Sumudu transform. The behaviors of the solutions are checked for different values of fractional order derivatives with the physical meaning with help of the Adam-Bashforth method and the Euler method.

For many people, the military and Buddhism do not seem to go together, especially in the West. However, during the past 200 years Nepali Buddhists (Gurkhas who are mainly Buddhists) have been serving in the British Army. There are nearly 600 more Buddhists serving in the UK Military at present. Via the author's personal experience, this paper seeks to investigate the religious and scriptural position of a Buddhist joining in and continuing in the military.

The paper records the experience of the first ever Buddhist Chaplain to HM forces and the first tri‐service annual Buddhist conference.

The aim of this paper is by no means to try to justify Buddist involvement in the military from any academic or theoretical point of view, but to share three years' experience from a practitioner's point of view.

As the first Buddhist Chaplain to the UK Armed Services, the author confirms what he has been doing over the past two years in order to assess the ethical position of Buddhist involvement with the military and explores the crucial issues surrounding this debate.

This case study allows students to appreciate the value of standard operating procedures in customer management. This case study emphasises the role of employees in delivering superior customer experience. This case study explores many facets of customer experience, reputation, social class membership and standard operating procedures (SOPs). Students will be able to apply theories of customer experience, behavioural psychology and service dimensions relevant to the airline industry. After completing this case study, students will be able to do the following:1. Evaluate the value of SOPs in Customer ManagementThis case study refers to the need for adhering to SOPs to deal with complex situations. Students will be able to evaluate whether compliance to SOPs could have helped Air India avoid the crisis or was it possible that a culture of absolute commitment to customer wellbeing could have prevented the crisis.2. Apply the theory of defensive attribution in customer grievance handling. Discuss if reducing customer effort in getting their problem solved can result in superior customer service.The victim had attributed the blame for not insisting on filing a complaint to the crew. Air India crew had defended their actions or lack of it by stating that they had followed the rule book. Students will be able to appreciate the need for a swift redressal mechanism to protect the self-image and self-esteem of the person/group involved. They will also understand that customer service interactions designed to solve customer problems swiftly and easily can be a very simple dictum to guide all employees in their decision-making while handling a customer complaint.

3. Evaluate the relationship between customer satisfaction and customer experience and examine the value of net promoter score (NPS) to study customer satisfaction.

Air India Airlines was catering to varied customer groups such as the Indian diaspora, large student population pursuing education abroad, first-time flyers and the rising middle class with travel aspirations. Customer expectations vary across segments and change over their lifetime. Airline staff must trace customer corridors and deliver on customer expectation across the touch points that matter to them to ensure meaningful and relevant service delivery. Students will have an opportunity to evaluate the NPS in measuring customer satisfaction and debate whether it is a sufficient metric to guide the organisation on delivering and monitoring customer experience.

4. Examine why reputation risk management and not crisis management should be the focus of Air India in delivering superior customer service because nearly 70%–80% of market value for a company comes from its intangible assets such as brand equity and reputation.

Students will discuss crisis management i.e. handling the threat to reputation after it has occurred and reputation risk management i.e. proactively managing potential threats to its reputation by taking timely actions to avoid or mitigate it. There are three factors (reputation reality gap, changing beliefs and expectation and weak internal coordination) that determine reputational risks. Students can evaluate this model to determine if Air India should address these three factors to manage its reputation proactively.

This case study is set around an incident that happened on 26 November 2022, on Air India flight bound for Delhi from New York when an inebriated 34-year-old man had peed on a 72-year-old woman. The perpetrator of the crime had walked free, and the victim was left dissatisfied with how the cabin crew had handled her ordeal. Air India Airlines was launched in 1932 by industrialist JRD Tata and nationalised in 1953. In 2021, Tata Group acquired the 90-year-old Air India from the Government of India for $2.4bn (INR 18,000 crore) and appointed Campbell Wilson as chief executive officer and managing director. The incident brought to the fore the customer management issues that Wilson had to address. First on the list of Air India’s turnaround plan was delivering “exceptional customer experience”. How was it going to achieve it because the Indian aviation ecosystem lacked infrastructure such as airports, airspace, competition and customer preference-based services? There was also shortage of pilots, engineers, technicians, air-traffic controllers and technocrats to occupy positions within security agencies and regulatory bodies. With Air India’s acquisition, the Tata Group had to find innovative solutions to deal with decades of internal neglect, non-performance and labour union problems. This case study is relevant to address real issues of customer experience, consumer psychology, reputation risk management and standard operating procedures in service management.

This case is suitable for both undergraduate and postgraduate level students of business management. It can also be used for training service personnel of aviation industry.

The purpose of this study is to explore the factors that influence sustainable homestay development and suggest a model for adopting and implementing the homestay concept and its contribution towards sustainable rural development in Uttarakhand, India.

Researchers have collected a total of 360 responses from tourists, homestay owners/villagers and managers associated with homestay businesses in Uttarakhand to examine, assess and analyse the data with the help of different statistical tools such as SPSS and AMOS to validate the concept of homestay and its impact on sustainable rural development.

The analysis uncovered that collaborative consumption, sharing economy and family feeling and community development are positively associated with and, in return, community development affects sustainable development.

This study enables us to explain the “collaborative consumption” in the context of homestays functional in the state of Uttarakhand only.

The study results in evidence of crucial implications for policymakers. Policymakers should focus on opportunities in tourism and its integration with economic, environmental and social goals. Homestays will be new avenues for economic and sustainable development.

Homestay offers reasonable and cheap lodging for tourists within the existing ancient homes, typically restored for the guests to form a comfortable stay. Homestay is adopted to facilitate community-based tourism in the state. It also helps in developing a source of livelihood for the community. It is helpful for individuals’ economic, social and aesthetic desires to be consummated by maintaining cultural integrity, ecological processes, biodiversity and natural support systems through homestay, as social entrepreneurship. Homestay has been envisaged as a driver to realise the sustainable development goals by steering the pathways to a property future for all involved within the elected hill states.

This study validates a new homestay model that will be useful for developing community and achieving sustainable development.
