The last chapter of this book grouped the studies that discusses and investigates the relationship between sustainability reporting and firm performance in three different regions: Europe, Mena and Africa. In Europe, the findings deduced from the empirical results demonstrate that there is significant positive impact of ESG on the performance. However, the relationship between ESG disclosures varies if measured individually; the environmental disclosure positively affects the ROA and TQ, whereas the corporate social responsibility disclosure negatively affects the three models. However, the corporate governance disclosure negatively affects the ROA, ROE and positively affect the Tobin's Q. In Mena, the empirical results show that there are differences in the impact of sustainability reporting (ESG) on firm's operational performance (ROA), financial performance (ROE) and market performance (TQ) between the sectors. Lastly, the findings from Africa show that there is a significant relationship between ESG and operational performance (ROA) and market performance (TQ) with ROA and TQ varying directly with the level of ESG disclosure. However, there is no significant relationship between ESG and financial performance (ROE).

The purpose of this study is determination of cadmium using silver-gold bimetallic nanoparticles (Ag-Au BMNPs) and an aptamer modified glassy carbon electrode.

The maximum response of modified electrode was obtained with, 50 mV pulse amplitude, 20 mV/s scan rate in phosphate buffer of pH 4.0. Ag-Au BMNPs, as the mediators improved electron transmit during the entire electron transfer process and the aptasensor response. Herein, the authors used aptamer as the capture probe to prepare an aptasensor with enhanced stability.

The proposed aptasensor exhibited a wide linearity to cadmium in the range of 0.001–0.100 µg/L with a low detection limit of 0.005×10⁻³ µg/L. The glassy carbon electrodes with Ag-Au BMNPs showed a lower detection limit.

This aptasensor has good reproducibility, stability and repeatability and is cost-effective to regenerate. The specificity and selectivity of the novel modified electrode is tested in the presence of other interfering metal ions such as Fe²⁺, Mn²⁺, Mg²⁺, Sb³⁺ and Bi³⁺. The aptasensor shows 10 times more sensitivity and selectivity for Cd²⁺ ions.

The purpose of this paper is to develop a sensitive and cost effective colorimetric sensor for detection of methyl parathion (MP) using simple circuitry. A simple and sensitive concept of colorimetric sensor instrument represents a rapidly expanding field of sensor techniques to monitor MP neurotoxins is described within certain conditions of producing color in samples. The variation of intensity of color with concentration provides discrimination between different concentrations of MP. The colorimetric instrument displays well‐defined signals towards hydrolyzed samples of MP.

The principle of light intensity measurement has been applied to measure various concentrations of MP based on Lambert‐Beer theory. This device and its processes are useful for quantitative analysis of MP. The detection limits were found within a range of 0.1‐1.5 ppm.

The experiments from sophisticated analytical techniques are costly and time‐consuming processes that validate the proposed system.

This paper's original proposition of using quantification of MP with colorimetric sensor instrument obtained promising results.

The colorimetric sensor instrument provides a new method for quantification of MP in unknown samples within detection limits.

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.

This paper aims to investigate the causal inferences between mobile application adoption and changes in travelers’ purchasing behavior regarding services supported by the travel and tourism industry.

Using a quasi-experiment conducted by an airline, data sets from more than 10,000 travelers were collected, and hypotheses were tested using propensity score matching and difference-in-difference methods.

Mobile application adoption has a significant positive effect on the total purchasing frequency of services and a significant adverse effect on booking tickets in advance and purchasing frequency from self-owned websites. Besides, this finding also suggested that members or travelers who had high average purchases in the past tend to buy more air tickets on average after mobile application adoption, while the number of days to book tickets in advance and purchase auxiliary services declined after mobile application adoption. However, males purchased more auxiliary services via mobile applications.

The study is based on the causal effect of mobile application adoption on purchasing behavior. Nevertheless, the theoretical basis remains relatively weak. Furthermore, the underlying mechanisms that cause the changes in purchasing behavior via mobile applications need to be elucidated.

This study enriches the hospitality and tourism literature on mobile application adoptions, multichannel purchasing behavior and revenue management. First, a quasi-experimental design is used to verify a causal relationship between mobile applications’ adoption and travelers’ purchasing behavior in the travel and tourism industry. Second, this study adds to examining travelers’ multichannel purchasing behavior in the travel and tourism industry. Third, this work enriches the current literature that explores auxiliary services and revenue management in the travel industry.

Mobile application adoption significantly impacted the travel and tourism industry. Besides, To the best of the authors’ knowledge, this is one of the first empirical studies that examined changes in purchasing behavior due to mobile application adoption from the perspective of service type. The findings provide the first evidence of the impact of mobile application adoption on service purchasing in the travel industry.

The study aims to understand how corporate social responsibility (CSR) and happiness are used together in various research studies to serve the ultimate goal of corporate sustainability (CS), which in turn contributes to sustainable development.

A systematic literature review (SLR) was made using Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) method in the two most-reputable databases of Web of Science (WoS) and Scopus, revealing a final list of 54 studies to analyse.

The review concludes that the literature on CSR and happiness provides three main findings: first, concerning the pillars of sustainability, most of the studies concentrate on people, neglecting the planet and profit, second, employees are subject to the highest number of studies as the target of CSR initiative and third, almost all studies employed the hedonic aspect of happiness in CSR literature.

This particular research finding points to the need for developing a comprehensive framework to assess stakeholder happiness from both hedonic and eudaimonic aspects from a CSR perspective which is then represented under the three pillars of sustainability.

To contribute to the ultimate goal of CS, management would design CSR initiatives for all stakeholders to increase both hedonic and eudaimonic happiness of them.

The literature provides reviews of research in CSR and happiness separately; however, there is not any research revealing how these two concepts are used together in studies and how this association could be read to serve the goal of CS.

The purpose of this paper is to measure the influence of peers, and the Government and non-governmental organization (NGO) initiatives on an individual’s attitudinal drivers such as environmental knowledge and environmental concern, which are the reasons for their green purchasing intentions. This concept was applied among the Indian young consumers.

For the research, a structured online questionnaire was used to obtain responses from 342 Indians from various cities. The participants were 20-25 years of age. SPSS software package was used to refine the data while SmartPLS was used to test the validity of the hypotheses.

The findings revealed that the Government and NGO initiatives along with peer influence do have a significant effect on a consumer’s environmental knowledge and environmental concerns. Further, this study found a significant positive effect of environmental knowledge and environmental concern on perceived value. In turn, the perceived value had a direct positive impact on green attitude leading to green purchase intention.

This paper provides critical insights for marketers, as well as for governmental agencies and NGOs promoting the conservation of the environment through environmental-friendly practices. These parties aim to generate greater awareness among consumers and impart knowledge about the benefits of green practices.

The studies measuring the impact of external factors on green consumption are scarce. Even the few studies available have measured the direct impact of external factors on green purchase intention. Governmental and NGO initiatives along with peer influence are the stimuli impacting operational factors such as environmental knowledge, environmental concern, perceived value, and green attitude, which, in turn, lead to the response of green purchase intention. This study provides new insights to this relationship by using a stimulus – organism – response framework.

The aim of this paper is to examine the motives behind the separation of household waste (or the lack of such separation) on the basis of the theory of interpersonal behaviour. The aim of this paper is to broaden and deepen the understanding of key determinants of household waste separation (or the lack of such separation). This study proposes a conceptual model based on the theory of interpersonal behaviour in combination with the focus theory of normative conduct.

A quantitative method was applied to investigate the views of 350 heads of households in the Johannesburg metropolitan area through an administered questionnaire. Structural equation modelling was employed to test the hypothesised structural relationships in the proposed model.

The results indicate that household waste separation intention is influenced by cognition of the consequences and by injunctive and personal normative pressures. Separation intention and past habits were found to have a direct influence on actual separation behaviour.

While the theory of planned behaviour is ubiquitous in the recycling literature, this study presents a different, broader framework for a better understanding of the drivers of household waste separation. This is achieved by applying the theory of interpersonal behaviour in combination with the focus theory of normative conduct. The findings provide insights that could help municipalities in emerging markets to promote household waste separation for better management of the environment.
