The purpose of the study is to analytically as well as numerically investigate the weight of throughflow on the onset of Casson nanofluid layer in a permeable matrix. This study examines both the marginal and over stable kind of convective movement in the system.

A double-phase model is used for Casson nanofluid, which integrates the impacts of thermophoresis and Brownian wave, whereas for flow in the porous matrix the altered Darcy model is occupied under the statement that nanoparticle flux is disappear on the boundaries. The resultant eigenvalue problem is resolved analytically as well as numerically with the help of Galerkin process with the Casson nanofluid Rayleigh–Darcy number as the eigenvalue.

The findings revealed that the throughflow factor postpones the arrival of convective flow and reduces the extent of convective cells, whereas the Casson factor, the Casson nanoparticle Rayleigh–Darcy number and the reformed diffusivity ratio promote convective motion and also decrease the extent of convective cells.

Controlling the convective movement in heat transfer systems that generate high heat flux is a real mechanical challenge. The proposed framework proved that the use of throughflow is one of the most important ways to control the convective movement in Casson nanofluid. To the best of the authors’ knowledge, no inspection has been established in the literature that studies the outcome of throughflow on the Casson nanofluid convective flow in a porous medium layer. However, the convective flow of Casson nanofluid finds many applications in improving heat transmission and energy efficiency in a range of thermal systems, such as the cooling of heat-generating elements in electronic devices, heat exchangers, pharmaceutical practices and hybrid-powered engines, where throughflow can play a significant role in controlling the convective motion.

This study explores whether the unique organizational form of family firms helps to mitigate the negative effects caused by the announcement of product recalls.

The authors use an event study, for a sample of 2,576 product recalls in the United States (US) automobile industry, between January 2010 and June 2021.

The authors found that stock market's reaction to a product recall announcement is less negative for family firms. This superior performance is partially driven by the family firms' long-term investment horizons and higher strategic emphasis on product quality. However, the relationship between family ownership and cumulative abnormal returns around product recall announcements is nonlinear as the impact of family ownership starts by being positive but becomes negative for higher levels of family ownership. The authors also find that family firm's chief executive officer (CEO) and managerial ownership influence positively the stock market reaction to product recall announcements.

This work has several implications for family firms' management as well as for investors and financial analysts. First, as higher managerial ownership is associated with a greater emphasis on product quality, decreasing stock market losses when a product recall occurs, family firms should consider increasing equity-based compensation. Second, as there seems to exist an optimal proportion of family ownership, family firms should consider the risks of increasing too much their ownership share. Third, investors and financial analysts can use the results in the study to help them in their investment and trading decisions in the stock market.

The authors extend the knowledge of product recalls by studying the under-researched role of the flexible, internally focused culture of family businesses on the stock market reaction to product recalls.

Very little is known about the influences of corporate strategy and regulation on the risk of regulated firms. The current study addresses this gap by examining the relationship among the level of diversification, the regulatory environment, and risk levels of regulated electric utility companies. Results suggest that both the regulatory environment and level of diversification impact firm risk. Specifically, the regulatory environment in which a firm operates moderates the relationship between diversification and risk. Electric utilities operating in the least favorable regulatory environments benefited the most from diversification in terms of risk reduction, while electric utilities in the most favorable regulatory environments experienced increases in risk from diversification. These findings extend previous studies by showing how both the regulatory environment and corporate strategy impact the risk of regulated utilities.

The relationship between diversification and organizational performance has been the subject of numerous studies over the years (Palepu, 1985; Rumelt, 1974). However, strategy scholars have universally defined diversification using a narrow definition, namely that corporate diversification is a function or reflection of the number of products/businesses in a firm's portfolio. The present study argues that such a definition has become outdated given the impact of international market diversification (Kim, Hwang, & Burgers, 1989; Rugman, 1979). Integrating these two views of corporate diversification, we investigate diversification‐performance differences using market‐ and product‐based measures of diversification and an international sample. Results suggest that the traditional model of diversification may not be applicable to all countries and that international differences exist.

Inspired by increasing public interest in corporate social responsibility (CSR) and the intensified focus of research on family firms (FFs) over the past few decades, the purpose of this paper is to analyze the existing literature on CSR in FF through a citation analysis.

This paper overviews the structure of research on CSR in FF, identifying influential publications, authors, and key lines of discussion. The authors identified the underlying sample through a systematic, keyword-based literature search of seven databases. Starting with this sample, the authors analyzed a database of 4,342 references of 3,025 different sources cited in the 63 articles.

The findings show that the cited literature on CSR in FF is widespread, confirming that the research field has great heterogeneity. The authors identified the most-cited researcher as Luis R. Gómez-Mejía (University of Notre Dame, USA), with 93 citations. The average author in the group of the 22 most-cited authors (with a three-way tie for 20th-most-cited author) counts 45.45 citations in the sample of 13.95 different sources. Because the citations mostly refer to journal articles, the authors further investigated the particular journals of publication. The 20 most-influential journals cover 45.28 percent of all citations, with the Journal of Business Ethics being the most influential (6.38 percent of all citations). Within the 3,025 different sources cited in the whole sample, the publication by Dyer and Whetten (2006), which is titled “Family firms and social responsibility: preliminary evidence from the S&P 500,” is the most-cited (29 citations in 46.03 percent of the analyzed 63 peer-reviewed journal articles).

The authors conclude with a call for more research on CSR in FF (especially qualitative case studies). Moreover, as scholars of North America and Western Europe dominate the current landscape of research, the authors would like to encourage scholars from other countries and cultures to provide insights from their countries.

In this chapter, the authors review emerging literature on multidimensional, information age-related phenomena across different disciplines to derive common themes and topics. The authors then proceed to analyse recent developments in these fields to provide an interdisciplinary overview of the most disruptive challenges for multinational companies (MNCs) competing in the modern information age. These challenges include more efficient peer-to-peer communication between stakeholders, crowd-organisation, globalisation of value chains and the need to organise knowledge resources. The aim of the chapter is not to review all age research, but to identify fundamental uncertainties for MNCs and discuss strategies of tackling such information age phenomena from an international business perspective.

The study developed and tested a model that attempts to describe the influence of ownership structure, diversification strategy, firm size and firm performance on CEO compensation. Results based on data from a cross‐sectional set of 216 Fortune 500 firms suggested that firm size, ownership structure and diversification strategy affect CEO compensation through the mediating effects of firm performance.

The purpose of this paper is to create a hierarchy of critical success factors affecting the higher technical education institutions, taking a case study of India. Using total interpretive structural modeling (TISM), the paper attempts to establish the inter-linkages among ten critical success factors for enhancing the performance of these institutions.

The paper employs Total Interpretive Structural Modeling (TISM) to understand the hierarchy of the factors and their interplay using response from 18 experts in the domain.

The findings reveal that autonomy and accountability coupled with availability of sustainable funds are the driving factors for the success of the institutions. Infrastructural facilities and establishment of centers of excellence act as amplification factors. Introduction of new programs and their accreditation, improvement in faculty quality, research output and improvement in performance of academically weak students emerge as process factors that drive the output factors, namely, academic performance and student placement.

The major limitation of this study is the scope that was limited to 191 institutions, as mandated in the project.

This study has important implications for the institutions as well as the policy makers to channelize their focus and efforts on driving and amplification factors that would ultimately lead to enhanced performance of the next generation higher technical education institutions.

This paper is a part of pan India project carried out to assess the performance of higher technical education institutions in India.

Family businesses dominate the economic landscape and contribute to the market for corporate control across the globe, either as acquiring companies or as target. However, there is still limited research investigating acquisitions by or of family firms. The authors begin to remedy this gap by providing a narrative review of extant research. Findings indicate that acquisitions in family firms are primarily regarded as a tool to solve succession problems, and not as a strategic tool to achieve growth. A greater dialog between acquisition and family business scholars can be an important means to improve theory and practice of acquisitions involving family businesses across the globe.

Being a micro-enterprise with heavy financial constraints, it was never easy to sustain the business at the time of pandemic. Mrs Jyoti Pruthi (owner of Pruthi Spices) made extraordinary efforts that would help her in survival of her business. She could not recover the business as it was before the pandemic. During such times, the loss of her husband was a setback. That incident broke Mrs Pruthi emotionally as well as financially. By taking some crucial managerial decisions, Mrs Pruthi strategized for the sustainability of her business. Now it was January 2022, after two years of the outbreak of the Covid-19 pandemic in the world. However, because of the market situation, her pressing dilemma was regarding business survival in such lean times.
