Abstract
Purpose
Workflow optimisation is crucial for establishing a viable acute stroke (AS) intervention programme in a large tertiary care centre. This study aims to utilise Lean Six Sigma (LSS) principles to enhance the hospital's workflow.
Design/methodology/approach
The Action Research methodology was used to implement the project and develop the case study. The study took place in a large tertiary care academic hospital in India. The Define-Measure-Analyse-Improve-Control approach optimised the workflow within 6 months. Lean tools such as value stream mapping (VSM), waste audits and Gemba were utilised to identify issues involving various stakeholders in the workflow. Sigma-level calculations were used to compare baseline, improvement and sustainment status. Additionally, statistical techniques were effectively employed to draw meaningful inferences.
Findings
LSS tools and techniques can be effectively utilised in large tertiary care hospitals to optimise workflow through a structured approach. Sigma ratings of the processes showed substantial improvement, resulting in a five-fold increase in clinical outcomes. Specifically, there was a 43% improvement in outcome for patients who underwent acute stroke revascularisation. However, certain sigma ratings deteriorated during the control and extended control (sustainment) phases. This indicates that ensuring the sustainability of quality control interventions in healthcare is challenging and requires continuous auditing.
Research limitations/implications
The article presents a single case study deployed in a hospital in India. Thus, the generalisation of outcomes has a significant limitation. Also, the study encounters the challenge of not having a parallel control group, which is a common limitation in quality improvement studies in healthcare. Many studies in healthcare quality improvement, including this one, are limited by minimal data on long-term follow-up and the sustainability of achieved results.
Originality/value
This study pioneers the integration of LSS methodologies in a large Indian tertiary care hospital, specifically targeting AS intervention. It represents the first LSS case study applied in the stroke department of any hospital in India. Whilst most case studies discuss only the positive aspects, this article fills a critical gap by unearthing the challenges of applying LSS in a complex healthcare setting, offering insights into sustainable quality improvement and operational efficiency. This case study contributes to the theoretical understanding of LSS in healthcare. It showcases its real-world impact on patient outcomes and process optimisation.

Abstract
This chapter uses a dataset of heights calculated from the femurs of skeletal remains to explore the development of stature in England across the last two millennia. We find that heights increased during the Roman period and then steadily fell during the “Dark Ages” in the early medieval period. At the turn of the first millennium, heights grew rapidly, but after 1200 they started to decline coinciding with the agricultural depression, the Great Famine, and the Black Death. Then they recovered to reach a plateau which they maintained for almost 300 years, before falling on the eve of industrialization. The data show that average heights in England in the early nineteenth century were comparable to those in Roman times, and that average heights reported between 1400 and 1700 were similar to those of the twentieth century. This chapter also discusses the association of heights across time with some potential determinants and correlates (real wages, inequality, food supply, climate change, and expectation of life), showing that in the long run heights change with these variables, and that in certain periods, notably the thirteenth and fourteenth centuries, the associations are observable over the shorter run as well. We also examine potential biases surrounding the use of skeletal remains.

Abstract
Theoretical basis
The case fosters discussions on basic concepts of entrepreneurship that include building a minimum viable product before launching a finished product, the importance of doing market research for early-stage startups, challenges in understanding an unfamiliar domain or industry and understanding the dynamics of business to business market.
Research methodology
Team Arnetta’s founders were interviewed in relation to the case. After the initial round of interviews, a product demonstration was given by Arnetta. Follow up interviews were conducted to delve-deeper into the problem while secondary research was conducted to understand the market dynamics and competitive landscape at the point in time in the case.
Case overview/synopsis
The four founders of Arnetta Technologies debate go-to-market timing for Integrated Breeding and Research Management Software, a data handling software for the R&D process followed by seed enterprises in India. The founders had spent over US$75,000 on the product development on which they had been working for more than one year. Two of the founders had given up their full-time jobs to work dedicatedly on the venture. The product was being customized to the requirements of their only client. Product development was taking longer than anticipated. To add to the challenges, international competitors had started capturing the Indian market. The founders had two options. First, they could wait and finish the product development before reaching out to their prospective clients – leading to delays and losing out on the market. Second, they could reach out to prospective clients and convince them to use the work-in-progress version of the product – which could turn out to be a deal breaker. The founders had to come to a consensus soon.
Complexity academic Level
The case is intended for students in undergraduate or graduate-level courses related to entrepreneurship, new venture creation, innovation management and business management.

Abstract
Tourism acts as a stimulant in rural poverty reduction and inclusive socioeconomic development. Sustainable tourism can significantly contribute to the economic diversification and local economic development of rural areas with its ability to create jobs and encourage infrastructural development focusing on preserving the environment, culture and indigenous groups. The detrimental effects of tourism on the economy, society and culture have shifted attention to sustainable travel. As a result, terms like ‘tribal tourism’, ‘ecotourism’ and ‘sustainable tourism’ have become popular. Inclusive engagement is a crucial agenda item in future tourism development and a major concern of many international organisations, including the United Nations. This chapter focuses on exploring the tribal communities and their involvement in sustainable tourism initiatives with an overarching focus on the role of the indigenous community and their skill sets in creating sustainable livelihoods through tribal tourism. Apart from creating direct and indirect employment opportunities, tribal tourism will support the growth of locally produced goods and have significant multiplier effects as capability-building initiatives will give impetus to the community's socioeconomic development.
Additionally, the sector offers notable advancements in the development of the tribal region. Tribal tourism will help people comprehend the significance of the ecosystem, local biodiversity and emission control activities on a deeper level (Thanikkad & Saleem, 2021). This chapter explores the indigenous tribes of Kerala and their ethnic skill sets, capabilities and means of livelihood. Further, the discussion on how the tourism domain promotes inclusive engagement of these tribes and aids in mapping skill sets, livelihood and inclusive engagement through tourism initiatives is explored.

Abstract
Purpose
The purpose of this paper is to investigate the effect of TiO2 nanoparticle content on the corrosion behavior of Ni‐Cr/TiO2 nanocomposite coatings applied by pulse‐reverse electroplating.
Design/methodology/approach
Ni‐Cr/TiO2 nanocomposite coatings with various contents of TiO2 nanoparticles were electrodeposited by pulse‐reverse method from a bath containing TiO2 nanoparticles to be codeposited and citric acid as the complexing agent. The surface morphology and the composition of coatings were studied by scanning electron microscopy (SEM) equipped by energy dispersive X‐ray system (EDS). The corrosion performance of coatings in the 0.5 M NaCl as a corrosive solution was investigated by potentiodynamic polarization and electrochemical impedance spectroscopy (EIS) methods.
Findings
It was found that the surface of Ni‐Cr/TiO2 nanocomposite coatings showed a finer structure that was more uniform and compact in appearance than was that of Ni‐Cr coatings. The incorporation of TiO2 nanoparticles in the alloy coating matrix improved the corrosion performance of the coatings and the higher content of nanoparticles gave better corrosion resistance.
Originality/value
Applying the Ni‐Cr coatings by the pulse‐reverse plating method eliminated cracks that were a problem in the Ni‐Cr alloy coating structure. Furthermore, the corrosion resistance was improved by the addition of TiO2 nanoparticles to the alloy matrix. This paper reports the optimum plating conditions that gave the better corrosion performance.

Abstract
Cyclic voltametric studies were carried out on mixtures of nickel sulphate, ferrous ammonium sulphate containing ethylene diamine tetra acetic acid, triammonium citrate, boric acid, Sodium chloride in the pH range of 8.5‐10.5 on platinum. The deposition of iron was found to involve the formation of FeOH+ and the second electron transfer is slow. The formation of iron nickel alloy film is anomalous. The charge transfer rates of FeOH+ and NiOH+ determine the deposition. Stripping voltametric curves revealed the dissolution of iron from an intermediate phase rich of iron in the iron‐nickel films.

Abstract
Purpose
Development of non‐destructive methodology for detection of arc strike, spatter and fusion type of welding defects which may form on steam generator (SG) tubes that are in close proximity to the circumferential shell welds. Such defects, especially fusion‐type defects, are detrimental to the structural integrity of the SG. This paper aims to focus on this problem.
Design/methodology/approach
This paper presents a new methodology for non‐destructive detection of arc strike, spatter and fusion type of welding defects. This methodology uses remote field eddy current (RFEC) ultrasonic non‐destructive techniques and K‐means clustering.
Findings
Distinctly different RFEC signals have been observed for the three types of defects and this information has been effectively utilized for automated identification of weld fusion which produces two back‐wall echoes in ultrasonic A‐scan signals. The methodology can readily distinguish fusion‐type defect from arc strike and spatter type of defects.
Originality/value
The methodology is unique as there is no standard guideline for non‐destructive evaluation of peripheral tubes after shell welding to detect arc strike, spatter and fusion type of welding defects.

Abstract
Purpose
The reduced ability of eyes to see clearly even with the use of glasses is known as the state of visual impairment. Among the many challenges faced, outdoor travel is one of them requiring to travel through surfaces, which has potholes and bumps.
Design/methodology/approach
The depth of the pothole and height of the bump is also conveyed to the user through different vibration pattern of various intensity. With available electronic travel aids, the visually impaired persons are still more inclined to rely on their white cane than carrying additional equipment for obstacle avoidance. In the system, all the components can be attached to the white cane, requiring no additional device to carry.
Findings
Upon experimentation with different obstacle types, the system obtained a 24.88% higher score in comparison to normal walking cane. A comparison with the state of the art available systems is also provided.
Originality/value
Moreover, the accuracy of the assistive cane can be heavily degraded if the cane is not properly held by the user. To restrict the user to hold the cane in only required orientation an alignment sensing switch is also proposed, which is missing in the current available literature.
