This study aims to cover the overall gamut of rapid prototyping processes and biomaterials used for the fabrication of occlusal splints in a comprehensive manner and elucidate the characteristics of the materials, which are essential in determining their clinical efficacy when exposed to oral surroundings.

A collective analysis of published articles covering the use of rapid prototyping technologies in the fabrication of occlusal splints, including manufacturing workflow description and essential properties (mechanical- and thermal-based) evaluation of biocompatible splinting materials, was performed.

Without advances in rapid prototyping processes and materials engineering, occlusal splints would tend to underperform clinically due to biomechanical limitations.

Three-dimensional printing can improve the process capabilities for commercial customization of biomechanically efficient occlusal splints.

Rapid technological advancement in dentistry with the extensive utilization of rapid prototyping processes, intra-oral scanners and novel biomaterial seems to be the potential breakthrough in the fabrication of customized occlusal splints which have endorsed occlusal splint therapy (OST) as a cornerstone of orthodontic treatment.

This paper aims to explore the importance of the role of national business systems (NBS) in shaping human resource management (HRM) and organisational behaviour (OB) practices in the context of Asian countries. To this end, this paper presents a comparative overview of different NBS in selected Asian countries and how these variously impact HRM and OB at two levels and contexts, i.e. within and cross-national.

The paper presents a topical review of the literature to unravel the complexity and challenges associated with studying this rich and complex area.

The findings suggest there is significant complexity in studying the impact of NBS on HRM and OB at a holistic and multi-level unit of analysis. The multiplicity of factors and levels of analysis, even at a level of within country analysis, highlights the sophisticated, in-depth and detailed nature of scholarship needed to unbundle and get a fuller understanding of this topic.

Although recent research presents a within and cross-national analysis of NBS and its impact on HRM and OB practices from diverse Asian countries such as India, Japan, Indonesia and Malaysia, recent research offers only a focused analysis of few targeted HRM and OB practices, rather than a collective or a bundle of HRM practices.

The contributions point to several practical implications for HR managers as well as managers from other fields, covering several national and cross-national comparisons.

This paper offers a substantial contribution in the understanding of how various HRM and OB practices are embedded in a nation’s business system and through a variety of historical and cultural influences.

This study aims to test the market anomaly of herding behavior driven by the response to supply chain disruptions in extreme market conditions such as those observed during COVID-19. The authors empirically test the response of the capital market participants for B2B firms, resulting in herding behavior.

Using the event study approach based on the market model, the authors test the impact of supply chain disruptions and resultant herding behavior across six sectors and among different B2B firms. The authors used cumulative average abnormal returns (CAAR) and cross-sectional absolute deviation (CSAD) to examine the significance of herding behavior across sectors.

The event study results show a significant effect of COVID-19 due to supply chain disruptions across specific sectors. Herding was detected across the automotive and pharmaceutical sectors. The authors also provide evidence of sector-specific disruption impact and herding behavior based on the black swan event and social learning theory.

The authors examine the impact of COVID-19 on herding in the stock market of an emerging economy due to extreme market conditions. This is one of the first studies analyzing lockdown-driven supply chain disruptions and subsequent sector-specific herding behavior. Investors and regulators should take sector-specific responses that are sophisticated during extreme market conditions, such as a pandemic, and update their responses as the situation unfolds.

The study aims at analyzing the adoption and preference of E-Marketing tools in five-star hotels in India. This paper also explores the scope of artificial intelligence and the challenges with regards to its application.

A qualitative approach is adopted for this research, wherein the data has been collected through conducting one on one telephonic interviews (some in questionnaire format) and a roundtable conference with the general managers and marketing communication managers of 30 New Delhi/National Capital Region (NCR) hotels respectively to understand the transition from traditional to digital marketing era and how are they using various social media marketing tools.

This study aims to inform how digitalization has benefitted the industry in various aspects and its comparison to the traditional marketing methods. It also discovers the future of artificial intelligence in the Indian hospitality space.

This study aims to help managerial decision-making in the application of various E-marketing tools and strategies, suggesting the right mix of both traditional and digital marketing platforms.

Arguably this is one of a kind study, as there has been no such research done specifically aiming at the five-star hotels of the Indian market. The findings will help the industry explore and enhance their digital presence by suggesting the appropriate mix of both traditional and digital approaches and can be used as a good source for further exploring the perspective of digitalization by academicians as well.

This study aims to investigate the effect of slanted perforation diameter in tabs for the control of Mach 1.4 underexpanded supersonic jet flow characteristics.

Numerical investigation was carried out for NPR 5 to analyze the effect of slanted perforation diameter in tabs to control the Mach 1.4 jet. Four sets of tabs with slanted circular perforation geometries (Φ_p = 1, 1.5, 2 and 2.5 mm) were considered in this study. The inclination angle of 20° (α_P) with reference to the jet axis was maintained constant for all the four tabs considered.

Determined value indicates there is a 68%, 71%, 73% and 75% drop in supersonic core for the Φ_p = 1, 1.5, 2.0 and 2.5 mm, respectively. The results show that the tabs with 2.5 mm perforation diameter were found to be efficient in reducing the supersonic jet core in comparison with other tab cases. The reduction in supersonic core length is due to the extent of miniscule vortices exuviating from slanted small and large diameter perforation in the tabs.

The concept of slanted perforation can be applied in scramjet combustion, which finds its best application in hypersonic vehicles and in noise suppression in fighter aircraft.

Slanted perforation and circular shapes with different diameters have not been studied in the supersonic regime. Examining the effect of circular diameter in slanted perforation is an innovation in this research paper.

This qualitative research examines the varied reasons for relocation to old age homes (OAHs) in contemporary India. The purpose of this study investigates the acceptance of institutional living in Lucknow (a Tier II city of India) and whether migration to OAHs is a voluntary decision. This study also examines the lifeworld of the older adult in these OAHs in an attempt to find out whether OAHs are conducive to positive ageing. Derivatively, the authors study their engagement/time use pattern and social networking patterns in the OAHs. Finally, the research seeks to learn whether OAHs are slowly substituting older adult care given within the family by offering the best of the facilities and services.

This qualitative research was conducted in two private OAHs in Lucknow, India. The findings of the study are based on 28 qualitative interviews conducted with the inmates, administrative staff and caretakers. The interviews were unstructured and open-ended and were supported by observations. The observation was not only made of the social setting but also the reaction of the participants. The idea was to develop an emic view of the subject by exploring valid narratives. Pseudonyms were used to report the finding so as to maintain the confidentiality of the research subjects.

This research moves beyond the traditional wisdom that people move to OAH because of the push factors within the family. OAHs in India have evolved over the years and high-end OAHs are equipped with modern amenities to cater to the upper class in their twilight years. Residents were found to lead active lives in OAHs and their common habitus and bonding capital helped them to face the vagaries of old age more confidently. Their active life and membership in various civic organizations challenge the contention of the role theory that the aged are more prone to lose rather than gain roles.

The originality of the research lies in the fact that the authors are extending the arguments made by the role theory of social ageing. The theory proposes that aged people are more likely to lose out roles rather than gain new ones. This study finds that the elderly tend to live a very active life in OAHs and engaged various civic organizations. Although they may lose/voluntarily give up the roles like the head of the household, spouse, etc., they acquire new roles in the context of OAHs.

As a result of the global COVID-19 pandemic, the entire world was left in shambles. The epidemic has had a profound impact on the way organizations used to function. It compelled all sectors and companies to change their working methods and move closer to virtual conceptions. Organizations that were able to adapt to the new environment have thrived, while the rest have struggled and continue to struggle. In today’s world, embracing virtual scenarios is more about perseverance and consistency than it is about making a conscious decision. Organizations such as NGOs have limited financial and non-financial means to adapt to such changes, and some of them were unable to suffice during the tough times.Despite this, the current case study focuses on the NGOs’ path during the pandemic: Kilkaari-Bachpan Ki. The NGO’s primary objective is to provide underprivileged children with free access to education. The current scenario illustrates how the Kilkaarians (team members of Kilkaari) modified their behavior in response to the crisis. To be used in an organizational behavior course, the case is intended for management students. Kurt Lewin’s model of change, which includes unfreezing, mobility and refreezing, can be understood by students. For this research, the authors use a case-study approach to explore how the organization responded when faced with a crisis.

This case is suitable for undergraduate students learning organizational behavior course, strategic management and also relevant to social work courses (social entrepreneurship/NGOs).
