This study aims to experimentally investigate the influence of considered process parameters, i.e. pulse on time, pulse off time, peak current and gap voltage, on tool wear rate (TWR) in electrical discharge machining (EDM) of iron (Fe)-based shape memory alloy (SMA) through designed experiments. The parametric optimization for TWR has also been attempted using the desirability approach and genetic algorithm (GA).

The response surface methodology (RSM) in the form of Box–Behnken design has been used to scheme out the experiments. The influence of considered process inputs has also been observed through variance analysis. The reliability and fitness of the developed mathematical model have been established with test results. Microstructure analysis of machined samples has also been evaluated and analyzed using a scanning electron microscope (SEM). SEM images revealed the surface characteristics such as micro-cracks, craters and voids on the tool electrode surface. SEM images provide information about the surface integrity and type of wear on the surface of the tool electrode.

The input parameters, namely, pulse on time and pulse off time, are major influential factors impacting the TWR. High TWR has been reported at large pulse on time and small pulse off time conditions whereas higher TWR is reported at high peak current input settings. The maximum and minimum TWR values obtained are 0.073 g/min and 0.017 g/min, respectively. The optimization with desirability approach and GA reveals the best parametric values for TWR i.e. 0.01581 g/min and 0.00875 g/min at parametric combination as pulse on time = 60.83 µs, pulse off time = 112.16 µs, peak current = 18.64 A and gap voltage = 59.55 V, and pulse on time = 60 µs, pulse off time = 120 µs, peak current = 12 A and gap voltage = 40 V, correspondingly.

Proposed work has no limitations.

SMAs have been well known for their superior and excellent properties, which make them an eligible candidate of paramount importance in real-life industrial applications such as orthopedic implants, actuators, micro tools, stents, coupling, sealing elements, aerospace components, defense instruments, manufacturing elements and bio-medical appliances. However, its effective and productive processing is still a challenge. Tool wear study while processing of SMAs in EDM process is an area which has been less investigated and of major concern for exploring the various properties of the tool and wear in it. Also, the developed mathematical model for TWR through the RSM approach will be helpful in industrial revelation.

The purpose of this paper is to systematically review the literature published on the various aspects of awareness about equity investment. The paper highlights the major issues and aspects with respect to equity investment awareness. It also aims to raise specific questions for future research.

The study is based on secondary information collected primarily through the review of existing literature.

It is found that the important determinants of equity awareness are demographic, socio-economic and psychological factors. Financial well-being is attributable largely to financial awareness. Growth of the financial market can be credited to equity awareness. Equity awareness enables an investor to make better financial decisions, to appreciate their rights and responsibilities and to understand and manage the risk as an investor.

Policy makers can design the equity awareness campaign considering the different demographic and socio-economic factors. While designing such a campaign, the impact and importance of equity awareness should be illustrated, considering their demographic and socio-economic profile.

This study is the first one using the literature review method in the area of equity investment awareness, in particular, and financial awareness in general. This paper will be useful to researchers, academicians and those working in the area of equity investment awareness and in their understanding about the various aspects of awareness about equity investment. The paper is first of its kind, hence original in nature.

The purpose of this paper is to analyse the US states and territories’ official tourism information websites based on the Web Content Accessibility Guideline (WCAG) and Section 508 guidelines to identify the compliance of websites towards disabilities policies and their behaviour pattern.

The official tourism websites of 57 states and territories were analysed through the TAW tool for WCAG 2.0 and AChecker for Section 508. Cluster analysis was used to produce a group of websites underlying the accessibility issues obtained from the online tool to understand the common pattern of behaviour.

The result revealed that websites have serious and significant accessibility issues underlying the prescribed guidelines that would interfere with the use of the website by disabled people. The main issues that make the website least accessible focussed on the following guideline of WCAG 2.0: compatible, navigable, text alternative, distinguishable and adaptable.

The empirical results provide the US states and territories’ tourism authority to better understand web accessibility in their websites and its impact on disabled people.

As the web plays an important role in individual lives, this study highlights the accessibility issues which need immediately focussed and technically planned actions from the respective states and territories to ensure that designed web content should communicate effectively and universally.

The chapter examines and challenges the assumed necessity of a linkage between remembered series of exchanges, amicable social relations, and prestige found in the work of Marcel Mauss and many subsequent theorists of reciprocity and gift exchange.

The chapter uses the nearly 500 year history of the giving and taking of the Koh-i-noor Diamond by rulers of South and Central Asia, commencing with Babur, the first Mughal emperor, and ending with Queen Victoria, which includes some gift giving and much taking by force, to explore what happens when only two of the three elements Mauss assumed central to understanding gift exchange are present.

Based on a review of the historical material, the chapter demonstrates that though historical narratives or memories of exchanges were central to enhancing the prestige of the parties to the exchange and the diamond itself, that process could and did occur in the absence of any on-going amicable social relations, including in situations in which exchange or transfer of the diamond were coerced and nothing was given in return to the dispossessed former owner of the gem.

By suggesting an alternative configuration of the factors necessary for the association of exchange and prestige, the chapter provides the opportunity to reconsider assumptions common in the literature on gift exchange and further enhance our understanding of this central element of social theory.

This study aims to examine the mediating role of employee commitment between the quality of work-life (QWL) and job performance among the faculty of technical institutions established in the province of Punjab (India).

The data collected from 434 faculty members with a response rate of 72% is analyzed and the mediation effect of employee commitment between the QWL and job performance of the faculty is modeled through partial least square-structural equation modeling.

The results indicate that employee commitment partially mediates between QWL and job performance. To strengthen the result, mediation of employee commitment is also tested for each dimension of the QWL with job performance. All the factors of QWL also supported a partial mediation effect.

The findings of the study may help the policymakers to understand, frame and implement appropriate policies for improving the work-life quality and commitment among the faculty. This may further assist in augmenting the overall performance of the faculty amidst a crisis in the sector.

The study highlights the role of employee commitment as a mediator between the QWL and job performance of the faculty in the technical education sector which is one of its kind and possibly not yet explored. Besides, the study proposes some measures in improving the work-life quality and job performance of the faculty.

This study aims to identify mutually exclusive risk categories and determine whether these categories effectively capture the potential impact of risk disclosures on the initial returns of initial public offerings (IPOs) in the financial and non-financial sectors.

Data were collected from 131 Indian IPO prospectuses (104 non-financial and 27 financial) issued between 2015 and 2021. Content analysis was performed to identify mutually exclusive risk categories, and the effects of these categories on initial IPO returns were assessed by regression analysis

The findings revealed that risk factor disclosures have a significant impact on underpricing, but not all risk factors are relevant. In the current study, in the financial sector, IPO underpricing was mostly driven by technological and competitive risk factors. In the non-financial sector, underpricing was predominantly influenced by operating risk and compliance risk factors.

The limitations of this study include the use of sentence-based context analysis, which does not assess the quality of risk disclosures. The statistical data reduction technique used to generate mutually exclusive risk categories may also be a limitation.

This research has the potential to assist companies in standardizing the disclosure of risks within IPO prospectuses. The insights gained can inform market regulators in designing policies aimed at aiding investors in formulating investment strategies, ultimately enhancing transparency and clarity regarding information disclosure. Moreover, the findings offer valuable guidance to investors in selecting IPOs aligned with their risk tolerance levels.

From a societal perspective, this study represents advancements by guiding regulators towards developing and regulating standardized, mutually exclusive risk factors. Such measures can aid investors in enhancing their decision-making perspectives regarding IPOs, promoting a more informed and confident investment environment.

This study is a pioneering attempt to address knowledge gaps by identifying distinct categories of risk disclosures in IPO prospectuses and examining their potential influence on IPO underpricing in the financial and non-financial sectors in India.

The purpose of this study is to examine the impact of corporate social responsibility (CSR) expenditure and business responsibility report (BRR) on a firm’s financial performance. Additionally, the study explores whether CSR expenditure and firm performance are related linearly or otherwise. The study also assesses the influence of mandating CSR expenditure on a firm’s performance.

The study is set in India and uses a nine-year data set from 165 companies listed on the Bombay Stock Exchange. Data compilation and analysis are done by using content analysis and panel data regressions.

The main findings of the study are that the effect of CSR expenditure on firm performance in India is non-linear and can be characterized as parabolic for investigated firms. While some performance indicators suggest a U-shaped relationship, others show an inverted U-type pattern, making a definitive conclusion elusive in either direction. BRR scores themselves have a positive impact on firm performance. Mandatory CSR expenditure affects the financial performance negatively, but the market performance improves in general.

The study provides new insights on the relationship between CSR expenditure, BRR scores and firm performance from India, which is not only a notable emerging market but also has other gripping characteristics. It has a prolific history of philanthropy, and yet, it is the first country in the world to mandate CSR expenditure in recent times. The equation between reported economic progress and general quality of life remains intriguing, and yet the number of studies on the effects of CSR expenditure on firm performance are no match to the volume of ongoing and completed works in more developed markets. This study attempts to trim the gap and provide some useful insights for managers, policymakers and stakeholders, apart from prompting further research.

The purpose of this study to identify and optimize the machining of polyvinyl butyral (PVB) material for industrial uses. The research is based on input machining parameters of rotary ultrasonic machining for better understand the output response surface roughness (SR) property of polyvinyl butyral (PVB) by using the Taguchi approach. The grey relational grade analysis (GRG) is also implemented to resolve the complex interrelationship of SR data for optimization and predicting and validate the results.

In experimental work, the input parameters, namely, concentration, abrasives, power rate, grit size, tool material and hydrofluoric (HF) acid has been selected. The experiment’s design was created using MINITAB Software; the L27 orthogonal array was selected for the experimentation. SR was examined with the GRG technique for process optimization. On the other hand, for single parameter optimization analysis of variance (ANOVA) has been used.

ANOVA optimization technique gives the best result on concentration (40%) of abrasive (Al2O3+SiC+B4C), power rate (40%), grit size (600), HF acid (1.5%) and tool material (D2 alloy) are the optimal parameters to provide the slightest degree of SR. GRG optimization of multi-response parameter setting: 40% concentration, SiC+B4C mixed abrasive slurry, 40% of power rating, 280 grit size, 0.5% HF acid and high-speed tool steel tool material gives better results. The SR of PVB glass material improved by 20% after grey relational analysis.

There are several practical applications in a variety of material processing sectors, including metallurgy, machinery, electronics and transportation. These real-world applications have produced substantial and discernible economic benefits.

The analytical and optimization results will be used in the various material processing sectors, including metallurgy, machinery, electronics and transportation.

The ANOVA and grey theory approaches offer the reader a primary picture of the machining research and process parameter optimization. Combined abrasive slurry of Al₂O3+SiC+B₄C with a high power-rating exhibits lower SR. Similarly, grit size is vital; larger grits produce better SR. Ra – 0. 611 m is the lowest SR value at the hole found in trial 25 after the experimentation.

The main purpose of the present study is to stretch the theoretical framework of existing stock of literature with reference to Risk Disclosures in IPO Prospectus and IPO performance. The systematic literature review study endows easy and quick access to researchers as well as categorization of the available literature.

Fifty research papers, which has been published or presented from 2000 to 2019 and are related to IPO risk disclosures and IPO performance, have been finalized. Further, these research papers were categorized based upon the five different variables to identify the probable research gap in the selected topic.

This review provides a coherent summary of past studies related to topic and develop a comprehensive evidence on relationship between disclosure of risk factors and IPO underpricing in short run. It shows the existing research gap that needs to be fulfilled to expand the research horizon of future research studies.

The sole limitation of the study is that being a systematic literature review study, it does not carry any empirical results.

The investors will be able to identify the key risk factors, disclosed in IPO prospectus, that may have probable dent on the short-term return from IPO. The findings will further help the investors and financial analyst to identify the degree of impact of risk disclosures that are listed in IPO prospectus.

The paper is a first of its kind to stretch the existing literature and develop theoretical framework in the context of risk factor discloses in IPO prospectus and IPO performance with reference to India. The present study is an attempt to integrate the existing gap between empirical research and existing literature and suggest the techniques to the future practitioners to widen the horizon of their research.
