Abstract

Purpose

Active infrared (IR) thermography, because of its high productivity and illustrativeness, is a promising technique in nondestructive testing (NDT). The purpose of this paper is to discuss a concept and practical implementation of a portable experimental unit intended for IR thermographic NDT of corrosion in metallic shells.

Design/methodology/approach

The basic theory relates to the analysis of heat conduction in a plate with rear-surface material loss subjected to pulse, thermal wave or arbitrary heating.

Findings

The amplitude of temperature anomalies over defects and their characteristic observation times depend on material loss, size and shape of corrosion defects. A flexible architecture of the inspection unit is proposed to include flash tubes, halogen lamps and laser-emitting diode (LED) panels as sources of stimulating thermal radiation. In particular, LED heaters might be perspective due to their narrow spectral band, which is beyond a spectral sensitivity of modern IR imagers. It has been found that the IR thermographic technique is convenient for detecting material loss of up to 15–20 per cent in uniformly painted steel shells with thickness up to 8 mm. The concept of signal-to-noise ratio has been applied to evaluate efficiency of data processing techniques, such as Fourier transform and principal component analysis.

Originality/value

The developed equipment and inspection guidelines can be used for detecting hidden corrosion in metallic objects, such as above-ground tanks, pipes, containers, etc.

Abstract

Introduction: Healthcare facilities have witnessed deterioration, limited employee engagement, and communication gaps due to a lack of wireless technology. The Internet makes work and life quicker and more intelligent. The Internet of Things (IoT) is a scheme of interconnection equipped with unique identifiers in recent years. Artificial intelligence (AI) and IoT advancement allow employees to develop competent and predictive services and solutions in human resource (HR) practices. This chapter has been formulated to summarise and classify the existing research and better understand the past, present, and future of employee engagement by improving IoT interrelated devices in the healthcare industry.

Purpose: This study aims to categorise and overcome the challenges involved in HR practices. Effectively embracing IoT application-connected devices in the healthcare industry can enhance human resources management’s (HRM) role and measure performance assessment to improve employee engagement and productivity.

Methodology: In this study, the authors develop propositions dependent on a theory-based review. A systematic analysis was applied to minimise the challenges of HRM. The subject-related articles from different journal sources, like Scopus, Emerald, Web of Science, Springer, etc., were analysed based on engagement criteria. It was graphically recorded in a collective and informative way to emphasise the review outcomes. The study has presented the positive impacts of AI and IoT on engagement in health care.

Summary: This chapter accumulated theory-based knowledge about healthcare employee engagement and how IoT-based technology like AI can optimise employees’ engagement effectively. Further, it draws comparative benefits for a workforce to execute performance advancements and create future progressive aspects for healthcare employees.

Abstract

The purpose of this chapter is to explain why ethical evaluation of the impact of a merger or acquisition matters, to place ethical evaluation of M&A in the wider context of knowledge of business ethics and corporate governance, and to develop and demonstrate a framework for evaluating the treatment of stakeholders during M&A. This contribution surveys the relevant governance, ethical and M&A literature. A new stakeholder framework is proposed and then applied to an important case study.

We found that M&A has important consequences for a variety of stakeholders; the strategy and finance literature has concentrated on top management and shareholders and neglected advisers, employees, customers, and suppliers. We also found that a stakeholder analysis framework can be adopted to evaluate each merger or takeover.

This chapter establishes a new framework for evaluating M&A beyond the conventional shareholder value approach; however only one case study is analyzed.

Managers and other stakeholders can use the proposed method to determine the likely impact of an M&A upon themselves and others and consequently weigh up the desirability of doing a deal in a wider context than currently.

The consequences for stakeholders following a merger or acquisition are often profound. The key protagonists ought to be more aware of these consequences which can be detrimental to stakeholders and the organization itself. The approach taken in this chapter provides a new method for both academics and practitioners to evaluate the impact of M&A.

Abstract

Purpose

The purpose of this paper is to examine whether corporate governance has an impact on portfolio selection within the usual mean‐variance framework, the idea being that by reducing agency conflicts, corporate governance increases the value of the firm.

Design/methodology/approach

Using a sample of 460 American firms between 1995 and 2004, the authors first determine the optimal mean‐variance portfolio. The authors then test whether governance characteristics explain the optimal portfolio weights.

Findings

The results show that the optimal portfolio weights are sensitive to internal control mechanisms, ownership concentration, managerial entrenchment and incentive compensation.

Originality/value

The results are relevant to academicians and investors concerned with portfolio selection. In fact, they underline the importance of including governance characteristics in their portfolio selection.

Abstract

EVERYTHING in the library world at the present moment is influenced by the uncertainty of the war situation. This note has run through our editorial comments for many months past, and as the spring of 1944 approaches it becomes even more insistent. The resumption of the bombing of London by the Luftwaffe, although some papers minimize it on the grounds that it will achieve no military decision, is nevertheless sufficiently disturbing to interfere with the immediate prospects of libraries there. It is difficult to arrange any of those extra activities— lectures, reading circles and the like—which gave a certain liveliness to London libraries, while there is prospect of an evening siren. Most libraries, however, are continuing their ordinary work at a higher pressure than they have known even in peace‐time, or at any rate their issues are maintained week after week at the best peace level.

Abstract

Purpose

From the agency theory’s point of view, this paper aims to analyze corporate governance mechanisms about the characteristics of the companies quoted in the segments Bovespa Mais and Bovespa Mais 2 and their influence on the creation of value in preparation for the opening of the initial public offering (IPO).

Design/methodology/approach

A quantitative approach was adopted to achieve the proposed objective using the panel data with fixed effects and secondary data collected on the Comissão de Valores Mobiliários website, using statistical software Stata® 13.0 for statistical tests. The population comprises non-financial companies belonging to the Bovespa Mais and Bovespa Mais Level 2 groups, as the survey sample took into account the period of adhesion of the companies, totaled in 15 companies, which cover the period from 2008 to 2019. The selected variables correspond to the ownership structure’s characteristics, then the board’s composition and the fiscal council as the body responsible for supervising the administrators’ acts.

Findings

The main results indicate that the number of independent members on the board of directors and the supervisory board’s participation positively influence market performance. However, it also reveals that the concentration of ownership brings fundraising for other companies’ acquisitions, risk reduction concerning information asymmetry between investing powers.

Research limitations/implications

The main results indicate that the number of independent members on the board of directors and the supervisory board’s participation positively influence market performance. Despite this, it also reveals that the concentration of ownership brings fundraising for other companies’ acquisitions, risk reduction concerning information asymmetry between investing powers.

Practical implications

This paper advances a comparative institutional perspective to explain capital market choice by firms making an IPO in a foreign market. This paper finds that internal governance characteristics (founder-chief executive officer, executive incentives and board independence) and external network characteristics (prestigious underwriters, degree of venture capitalist syndication and board interlocks) are significant predictors of foreign capital market choice by foreign IPO firms.

Social implications

While product market choices have been central to strategy formulation for firms in the past, financial markets’ integration makes capital markets an equally crucial strategic decision. This paper advances a comparative institutional perspective to explain capital market choice by firms making an IPO in a foreign market.

Originality/value

This situation generates value to shareholders and is perceived by the market and, ultimately, generates a direct relationship with the market performance of companies. While product market choices have been central to strategy formulation for firms in the past, financial markets’ integration makes capital markets an equally major strategic decision.

Abstract

Purpose

Mergers and acquisitions (M&As) are important strategic actions undertaken by firms to access resources and markets. However, firms face substantial challenges in M&As during deal completion. While prior literature reviews synthesize the studies on the post-merger consequences of M&As, the literature on deal completion is largely fragmented. In this paper, the authors synthesize prior literature on deal completion into the antecedents and consequences framework and map various studies across the international business and management, finance and accounting literature at the macro-, meso- and micro-levels.

Design/methodology/approach

The authors adopt a content analysis-based methodology to conduct the review. First, the authors identify existing literature on deal completion based on keyword searches. Next, the authors propose a framework that integrates the extant literature from a multi-theoretic perspective across four broad themes: concepts, antecedents, implications and moderators. In this study, the authors consider not only empirical but also conceptual papers to strengthen the theoretical foundations of M&A literature. Finally, after synthesizing various studies, the authors highlight a future research agenda on deal completion.

Findings

Based on the review, this study provides important avenues for future research on M&A deal completion.

Originality/value

This study theoretically integrates multi-disciplinary and multi-country research on acquisition completion.

Abstract

Purpose

The purpose of this study is to provide a broad understanding of the pre-completion stage and subsequent abandonment of mergers and acquisitions (M&As).

Design/methodology/approach

A total of 117 peer-reviewed, English language articles published in scholarly journals were considered in the review. The approach includes a descriptive evaluation of the literature, coupled with content analysis. The paper uses both positivist and constructivist approaches to qualitative research. The analysis is conducted with the help of R programming and Gephi visualization software. The authors organize the work around the event of outcome/closure of deal proposal.

Findings

It is found that earlier studies sampled on domestic M&As in developed economies (DEs). However, the interest of scholars has increased in cross-border deals and emerging economies (EEs) in the last decade. Various factors interact and facilitate the completion/abandonment of good and bad deals. The authors find that complex non-linear relationships exist, and there is a need for studies with other classification techniques focusing on predictive accuracy.

Research limitations/implications

The literature review is limited to articles available to the researcher using search terms related to M&A completion/termination. The databases accessed were: ProQuest, Scopus and Web of Science. However, backward snowballing was performed to avoid the omission of relevant articles.

Originality/value

The findings and subsequent discussions familiarize researchers and practitioners with an overview of research undertaken in the field of M&A abandonment. The authors find voids within the literature and suggest future research agendas.

Abstract

Purpose

In this paper, the authors examine options trading in firms that soon become rumored takeover targets. This study also examines whether measures of informed trading can predict target returns (upon rumor announcement and over the post-rumor period) and/or predict which rumors lead to bids. The authors further assess whether the informed trading they observe is more prevalent in the options market or the equity market.

Design/methodology/approach

This study calculates abnormal options volume using a market-model approach that accounts for different attributes of options trading. The authors construct a control sample and compare equity options trading of firms in their sample with that of the control sample. In addition, the authors fit a series of regressions to examine whether pre-rumor abnormal options trading can predict rumor accuracy in a multivariate setting.

Findings

The authors find that the volume of options traded is abnormally high over the pre-rumor period while the direction of option trades (abnormal call volume minus abnormal put volume) prior to takeover rumors predicts forthcoming takeover announcements, rumor date target firm returns and post-rumor target firm returns. The results are robust when controlling for publicly available information, when using a control sample, and when using alternative measures of informed trading.

Originality/value

This study is the first to provide evidence of informed options trading prior to a broad sample of takeover rumors. In addition, this study contributes to the literature on takeover predictability and profitability by showing that various pre-rumor measures of informed options trading significantly predict bid announcements. The authors also contributes to the literature on price discovery by providing evidence that informed investors are more likely to trade in the options market than in the equity market during the pre-event period.
