Abstract

Purpose

The primary purpose of this work is to prepare the renewable source-based polyurethanes coatings which can be used to substitute petroleum-based materials. In the secondary purpose, the paper included improvement in the properties of said PU coatings using modified nano TiO2 for industrial PU coatings.

Design/methodology/approach

The authors have synthesised low molecular weight polyols (monoglycerides) based on vegetable oils such as castor, linseed, coconut, mustard, sunflower and rice bran oils. These monoglycerides were successfully utilised in the preparation of polyurethane coatings. In order to improve the performance of these coatings, modified nano TiO2 was incorporated into them. The particle size of TiO2 was determined by transmission electron microscopy. Coatings prepared were characterised for their properties such as gloss, scratch resistance, impact resistance, flexibility, cross cut adhesion and chemical resistance. The thermal stability of coatings was also studied by thermo gravimetric analyzer.

Findings

The polyurethane coatings prepared from six monoglycerides of different oils with polymeric diphenyl methane diisocyanate showed good chemical resistance and thermal stability. Coating properties like impact resistance, flexibility and adhesion were excellent for all of the prepared samples of PU coatings. PU coatings with excellent hardness up to 5B were found with the modification of nano TiO2 by silane coupling agent. The authors successfully prepared the renewable source-based (monoglycerides of oil) PU coatings.

Practical implications

Practically the authors are able to convert renewable source that is vegetable oils into polyurethane coatings which may have strong potential to be used as industrial surface coating. The properties of the PU coatings were evaluated before and after the incorporation of different concentration of surface-modified nano TiO2 which revealed that the presence of 1 percent nano TiO2 showed significant enhancement in coating properties.

Originality/value

The beauty of this work includes synthesis of polyurethanes coatings from renewable source material (monoglycerides of vegetable oils) to substitute petroleum-based materials. The incorporation of silane-modified TiO2 nanoparticles in renewable source-based PU coatings is another originality of the work. This article is also representing comparative study of various vegetable oils on PU coatings.

Abstract

This chapter aims to analyse the evolution of research in the Indian tourism and hospitality domain from 1976 to 2021. By employing the bibliometric and systematic literature review, the chapter highlights the prominent authors, institutions, methods, emerging and explored research themes in the tourism and hospitality field. Accordingly, the authors collected 458 articles from core tourism and hospitality related journals using PRISMA and evaluated them using VOSViewer. The findings revealed an emic perspective of research contribution in Indian tourism and hospitality. While some topics such as religious tourism, sustainability, cultural and heritage tourism products have attained more attention, topics such as tourism entrepreneurship, technology and human resource development failed to seek attention in the eyes of journals and researchers. Although the literature has expanded significantly, there is a need to build global academic networks to examine the state of Indian tourism and hospitality. The chapters suggest that future research should critically evaluate the schemes and initiatives undertaken by the government to promote Indian tourism, expand research to western and eastern parts of the country, and follow the mixed-method research to contribute holistically to the topic.

Abstract

Rivigo, a new entrant in the trucking business in India, believed that a new paradigm in the trucking/logistics industry could be brought about that would not only improve the quality of service dramatically, but also upgrade a truck driver's lifestyle. While the industry faced driver shortage largely due to long stays away from home, Rivigo hoped to attract drivers by offering them roles which would bring them back home in 24 hours. Drivers would be part of a relay, handing over the truck at pit stops. Further, they leveraged an IT-enabled IoT platform on a fleet of owned trucks. All this revolutionized most of the traditions then followed in the industry. The entrepreneur and his core team comprised professionals from premium institutes of the country, with experience in professional organizations in related domains. By offering services like assured delivery at half the time and full shipment visibility, Rivigo had to charge a premium to market segments that would value this. The case raises the question of sustainability in the future.

Abstract

Purpose

Owing to business uncertainty, it is prudent for organizations to rely on temporary employees to achieve numerical flexibility. This paper investigates the effect of perceived investment in temporary employee development (PITED) on organizational performance (OP) through the mediation process of organizational identification (OI), work engagement (WE) and the moderation process of perceived human resource policies (PHRP). A conceptual framework was built on social exchange theory and job demands-resource theory.

Design/methodology/approach

Data was collected from skilled temporary employees deputed at client organizations in the information technology business process management (IT-BPM) industry. Analysis was done using the partial least squares-structural equation modelling (PLS-SEM) method using SmartPLS 3.0 software.

Findings

The study established a significant association between PITED, OI and OP, in which OI acts as a partial mediator. In contrast, the mediating relationship of WE between PITED and OP was insignificant. PHRP moderated the relationship between PITED and OP.

Practical implications

This research suggests to top management and human resource leaders that PITED makes temporary employees identify with client organizations, resulting in increased OP.

Originality/value

This research builds on theoretical assumptions to adopt a temporary employee perspective on organizational initiatives and performance in the IT-BPM industry, which is uncommon.

Abstract

Some of the azoles have been studied as inhibitors towards the corrosion of nickel in 4% HNO3 solution, using electrochemical polarization technique, at various concentrations of inhibitors and at different temperatures (25, 35, 45°C). All the inhibitors investigated were able to suppress both the anodic and cathodic processes appreciably, hence act as mixed inhibitors. Among these inhibitors, 2‐mercaptobenzothiazole was found to be the most effective inhibitor to control the corrosion of nickel in nitric acid solution.

Abstract

Purpose

The objective of this paper is to contextualize the recently developed process of toxic leadership (PTL) model to international business (IB) intercultural (IC) contexts. This is important because of the potential for cultural conflict to compromise organizational spiritual capital, a crucial driver for success defined by the bottom-line and employee satisfaction. Thus, the paper addresses the gap that is imperative for practical societal reasons of realizing the United Nations Sustainable Development Goals (UN SDGs), because the bottom-line is an important driver for international partnerships, a crucial element of SDG 17 and inclusivity is a contributing element of SDG 8 that pertains to decent work.

Design/methodology/approach

A case study design was adopted to facilitate modification of existing theory. Semi-structured interviews were conducted in Japanese (IB/IC) contexts to understand the lived experience of Japanese business leaders and host country managers (followers) in the USA and India. A social constructivist thematic analysis was deployed to examine the data.

Findings

Our study illustrates the degree to which the PTL model ports to IB situations, with a refinement on the workarounds for resistance by host country employees. The findings suggest that policymakers seduced by IB business market opportunities also need to address the dark side of these activities by ensuring proactive measures, such as language training and cross-cultural awareness, to ensure decent work as perceived by the follower.

Research limitations/implications

This research discusses implications for the evolving zeitgeist of human-centrism in organizations. Although the adopted subjectivist interpretivism presents a concomitant limitation of generalization, the research nevertheless successfully raises flags against the hegemonic positive assessment of the UN SDGs.

Practical implications

Connections to international subsidiary leadership selection are offered. Additionally, the research raises the specter of breach in leader–follower trust compromising organizational spiritual capital.

Social implications

Our research shows that society should consider potential misalignments with human centricity when promoting international partnerships, such as in the name of the UN SDG 17.

Originality/value

The PTL model is relatively new to leadership scholarship. The present paper is novel in extending it to IB’s intercultural contexts. Moreover, as an exemplar of its application, it challenges and adds nuance through adjustment and ambiguity to the generally positive assessment of Japanese leadership in the conventional leadership literature.

Abstract

Currently, waste is regarded as a symptom of inefficiency. The generation of waste is a human activity, not a natural one. Currently, landfilling and incinerating wastes are common waste management techniques; but the use of these methods, in addition to wasting raw materials, causes damage to the environment, water, soil, and air. In the new concept of “Zero Waste” (ZW), waste is considered a valuable resource. A vital component of the methodology includes creating and managing items and procedures that limit the waste volume and toxicity and preserve and recover all resources rather than burning or burying them. With ZW, the end of one product becomes the beginning of another, unlike a linear system where waste is generated from product consumption. A scientific treatment technique, resource recovery, and reverse logistics may enable the waste from one product to become raw material for another, regardless of whether it is municipal, industrial, agricultural, biomedical, construction, or demolition. This chapter discusses the concept of zero landfills and zero waste and related initiatives and ideas; it also looks at potential obstacles to put the ZW concept into reality. Several methods are presented to investigate and evaluate efficient resource utilization for maximum recycling efficiency, economic improvement through resource minimization, and mandatory refuse collection. One of the most practical and used approaches is the Life Cycle Assessment (LCA) approach, which is based on green engineering and the cradle-to-cradle principle; the LCA technique is used in most current research, allowing for a complete investigation of possible environmental repercussions. This approach considers the entire life cycle of a product, including the origin of raw materials, manufacturing, transportation, usage, and final disposal, or recycling. Using a life cycle perspective, all stakeholders (product designers, service providers, political and legislative agencies, and consumers) may make environmentally sound and long-term decisions.

Abstract

Purpose

The purpose of this study was to optimize meat slices for processing attributes to produce better sensory features in developed products from buffalo veal and chevon. The processing parameters such as meat particle size, fat content and binding ability without chopping were the subject of this study.

Design/methodology/approach

The study involved three experiments where the particle size, fat content and tumbling time were optimized for optimum binding and improvement in different sensory attributes of product followed by physico-chemical analysis.

Findings

The sensory scores clearly indicated that meat slices prepared from 3 mm meat particle size, 10% fat content and 1 h tumbling time were having best sensory features. The selected product was analyzed for different physico-chemical properties. Emulsion stability and cooking yield revealed significantly (p = 0.01) higher values of 91.6% and 89.7%, respectively, in buffalo veal than in values of 87.6% and 84.9%, respectively, in the chevon product. Similarly the results showed that buffalo veal slices had significantly (p = 0.01) higher (17.4%) protein than the chevon (15.2%), whereas chevon slices had significantly (p = 0.01) higher (10.3%) fat content. The texture profile analysis indicated that cohesiveness (p = 0.01) and chewiness (p = 0.05) were significantly higher in chevon product than in buffalo veal.

Originality/value

The study was conducted to explore the buffalo veal as a potential source of quality meat, as majority of buffalo meat produced in India from spent animals have compromised quality attributes. The comparison was done with chevon, the most popular red meat in the country for the comparative study.

Abstract

Purpose

The study aims to draw on existing knowledge and investigates how luxury is perceived in a developing nation with economic and cultural diversity. The present study aims to develop a conceptual framework to understand luxury buying behavior in a developing nation context.

Design/methodology/approach

The study utilizes qualitative research (focus group discussions) with 72 luxury consumers (and partly with practitioners) of apparel and accessories in two major metro cities and two major non-metro cities of India.

Findings

A framework of luxury buying behavior was constructed with cultural background, antecedents, buying process and post-purchase consequences of luxury buying behavior as its sub-constructs. Gender was identified as a moderating variable between antecedents of purchase and purchase behavior.

Research limitations/implications

The most important contribution of the present study is the creation of a comprehensive framework of luxury buying behavior within a developing nation context and a set of testable propositions to further validate using quantitative research.

Practical implications

Provides the manager with a workable model of luxury buying behavior that he/she could use to generate the right consumer responses.

Originality/value

The present study is the first of its kind which integrates cultural backdrop, antecedents and consequences of luxury consumption in the context of a developing nation.
