This study aims to scrutinize time-varying return and volatility interlinkages among major cryptocurrencies, NFT tokens and DeFi assets between 1 July 2018 and 19 February 2023 and determine optimal portfolio allocations and hedging effectiveness under different portfolio construction techniques.

This work examines time-varying return and volatility interlinkages among major cryptocurrencies, NFT tokens, and DeFi assets between 1 July 2018 and 19 February 2023. To this end, the time-varying parameter-vector autoregression (TVP-VAR)-based connectedness methodology of Antonakakis et al. (2020) This approach is an extended version of the Diebold–Yilmaz (DY) method (Diebold and Yılmaz, 2014) and has advantages over the original DY. First, unlike the DY, it is free of the selection of a particular window size. Second, it has robustness for the outliers. Furthermore, following Broadstock et al. (2022), the author estimates time-varying optimal portfolio weights and hedging effectiveness under different portfolio construction scenarios.

This study's results indicate the following results: (1) The overall connectedness indices prominently capture well-known financial/geopolitical distress incidents; (2) the leading cryptocurrencies (ETH, BTC and BNB) are the largest transmitter of return shocks, while LINK and BTC are the largest transmitters/recipients of volatility shocks; (3) cryptocurrencies, NFTs and DeFi form distinct cluster groups in terms of return and volatility connectedness; (4) the connectedness networks estimated around the 2022 cryptocurrency crash and the FTX's filing for the bankruptcy are characterized by the strongest return and volatility interlinkages; (5) optimal portfolio strategies computed by different portfolio construction techniques display similar motifs and have sustained growth paths except for some short-lived drop backs.

This study's findings imply several policy suggestions for investors, stakeholders and policymakers. First, the study's time-based dynamic interlinkages can help market participants in their optimal portfolio decisions. In particular, the persistent net receiving roles of the DeFi assets and the NFTs throughout the episode, especially around the financial/geopolitical turmoil, underpin their safe haven potentials (Umar et al., 2022a, b). Finally, since the total connectedness indices (TCIs) are prone to significantly increase around financial/geopolitical burst times, these tools can be valuable for policy makers to monitor risk.

The contribution of knowledge is at least threefold. First, the author focuses on the dynamic time interlinkages among major cryptocurrencies, NFTs and DeFi assets in July 2018 and February 2023 considering the prominent recent financial/geopolitical incidents. Second, the author estimates network topologies of dynamic connectedness around financial/geopolitical bursts and compared them in terms of interlinkages. Finally, the author calculates the time-varying optimal portfolio allocations and hedging effectiveness under different portfolio construction techniques.

This paper aims to propose and assess a framework to analyse the institutionalization of Industry 4.0 (I4.0) through a framing analysis.

The framework was developed by combining the institutional approach with orders of worth, drawing insights from a comprehensive literature review. To assess it, the authors conducted a qualitative analysis of annual reports from companies with the largest market capitalization over a six-year period and interviewed union representatives in Spain and Sweden.

The framework comprises five dimensions (industrial, market, civic, green and connectionist). The empirical results reveal that companies consistently frame I4.0 with an emphasis on industrial and market perspectives. In contrast, unions place a stronger emphasis on civic issues, with Spanish unions holding a more negative view of I4.0, expressing concerns about working conditions and unemployment.

The proposed framework brings interesting insights into the dispute over the meaning of I4.0. Although this empirical study was limited to companies and unions in Sweden and Spain, the framework can be expanded for broader investigations, involving additional stakeholders in one or more countries. The discussion outlined using the varieties of capitalism approach is relevant for understanding the connection between the meso and macro levels of this phenomenon.

In navigating the landscape of I4.0, managers should remain flexible, and ready to tailor their strategies and operations to align with the distinct demands and expectations of stakeholders and their specific institutional environments. Similarly, policymakers are urged to acknowledge these contextual intricacies when crafting strategies for implementing I4.0 initiatives across national settings.

Based on the empirical findings, this study underscores the importance of fostering social dialogue and involving stakeholders in the implementation of I4.0. Policymakers and other stakeholders should take proactive measures, tailored to each country’s context, to mitigate potential adverse effects on labour and workers.

The study presents a novel framework that facilitates the systematic comparison of I4.0 framing by different actors. This contribution is significant because the way actors frame I4.0 affects its interpretation and implementation. Additionally, the aggregate analysis of results enables cross-country comparisons, enhancing our understanding of regional disparities.

The purpose of this study is to evaluate the effectiveness of a self-stigma reduction programme on self-stigma.

A randomized controlled trial was conducted from November 2017 to December 2018 with 278 people diagnosed with schizophrenia (PDwS). Participants were randomly assigned to receive a self-stigma reduction programme (psychoeducation, cognitive behavioural therapy and social skills training) or treatment as usual.

PDwS in the intervention group experienced a greater reduction in the level of self-stigma (20.19 vs −0.62; p < 0.001) at post-intervention and (37.35 vs −0.66; p < 0.001) at six-month follow-up.

The first RCT examines the problem and implements intervention in middle east country. Also, the authors have conducted high-quality RCT.

Regulatory focus theory suggests that regulatory fit influences individuals' decisions. However, little is known regarding the effect of regulatory fit on sports consumers' purchase intention. Accordingly, the authors extend the concept of regulatory fit to the sports context to understand how advertising claims affect amateur badminton players' purchase intention of badminton rackets.

A total of 200 amateur badminton players participated in this study. These participants were randomly assigned to the promotion-prime advertising claim or prevention-prime advertising claim condition.

Authors’ findings demonstrate that the experience fit between personal regulatory focus in the sports context and advertising claims induces higher purchase intention. This finding corresponds with expectations based on regulatory focus theory.

The present study extends and strengthens knowledge of personal regulatory focus in the sports context and thus shows marketers how to communicate with target customers to precisely sell sports products using the regulatory fit strategy.

This chapter provides an introduction to the world of family companies and family constitutions from a legal perspective. It first studies the legal types of business organizations that family firms have chosen across time and jurisdictions. It then illustrates how early predecessors of family constitutions evolved in the late Middle Ages and what modern family constitutions look like in different countries today. Further considerations are devoted to the governance framework of family firms. The chapter concludes by exploring the potential legal effects of family constitutions under German company and contract law.

The aim of the article is to determine research areas and to recognize the current direction in the development of maturity models, to indicate the key areas of organizational maturity models (OMMs) development and their classification as well as to pinpoint research gaps and areas of potential development of OMMs in the context of scientific research and the needs of management practitioners.

The research was conducted using the literature review method, bibliometric analysis and visual mappings.

The empirical classification developed in this paper identified 12 categories based on management areas, constituting the criteria for classifying OMMs models, where OMMs are being developed: Information Technology, Project Management, Business Management and Strategy, Human Resource, Ergonomics, Health and Safety Management, Industry 4.0 concept, Knowledge Management, Process Management, Performance Management, Quality Management, Supply Chain Management, Risk Management and Innovation Management.

The main limitation is the analysis in the scope of topic OMMs including solely the Scopus and Thompson Reuters Web of Science database. Another shortcoming is conducting data analysis and classification based on the abstracts of the selected articles.

This work is a starting point to prospect trends for future revolving around the OMMs crossing different databases.

The current study investigates the impact of directors' attributes on the extent of compliance with International Financial Reporting Standards (IFRS) fair value disclosure requirements. The attributes investigated include directors' human capital (accounting qualification) and social capital (political association), directors' share ownership and the power distance between the chief executive officer (CEO) and the rest of the board members.

The study uses disclosure analysis to measure the extent of compliance with the fair value disclosure requirements of IFRS. Ordinary least squares (OLS) regression is used to test the relationship between the disclosure score and directors' attributes. Data were collected from the annual reports and websites of the sample companies.

Contrary to conventional belief, this study's findings suggest that directors' social capital and the power distance between the CEO and the rest of the board act as more powerful factors than directors' human capital in explaining corporate mandatory disclosure. Specifically, the results indicate that powerful actors form a dominant coalition and co-opt influential constituents from the institutional domain to neutralize the effect of legal coercion and the accounting expertise of board members and Big Four audit firms on the extent of compliance with institutional (fair value) rules.

This study utilizes Oliver's (1991) framework of strategic response to institutional processes in the Bangladeshi context. Although the study provides new insights into corporate disclosure practices, findings are not generalizable due to different institutional settings in different countries. Therefore, future studies could replicate the approach in different institutional settings.

The findings of this study will be of interest to the International Accounting Standards Board (IASB) as it focuses on a developing country that has adopted IFRS 13 and other fair value-related standards relatively recently.

The disclosure analysis contained in this study represents the first comprehensive analysis of the extent of compliance with the fair value disclosure requirements of IFRS. Furthermore, this study considers the impact of directors' social capital and finds that it is a more powerful determinant of the extent of compliance with IFRS as compared to human capital.

The practice of corporate chief executive officer (CEOs) engaging in sociopolitical activism on issues both related and unrelated to their companies is gaining attention in the popular press and among management scholars. The purpose of this paper is to explore the antecedents and motivations of CEO sociopolitical activism in a typology of influences internal and external to the CEO and to the organization. This study’s typology highlights the need for greater understanding of CEOs’ sociopolitical activism for the CEO as an individual actor and for the company they represent.

This study’s approach is to conceptually review the literature on CEO activism and to create a theoretic framework for future analysis of the antecedents and motivations and ramifications of CEOs’ sociopolitical activism for the CEO as an individual actor and for the company they represent. The author highlights four theories and seeks future application of these theories to the phenomena in a typology.

The typology highlights the application of management theories to various ramifications of CEO activism to four influences on CEO activities. Upper echelons theory helps explain the motivation of a CEO internally, whereas agency theory applies to CEO activism internal to the CEO and external to the organizational operations. External to the CEO, organizational culture theory supports responses internal to the organization, and stakeholder theory provides insight into responses external to the CEO and the organization.

This study provides conceptual support for the study of CEO activism and encourages future research on the topic.

The aim of this study is to examine the impact of foreign direct investment (FDI) inflow and information and communication technology (ICT) on the economic performance of India by analysing annual data from 1991 to 2019.

This study has used data collected from secondary sources. The variables considered for the analysis are based on the review of theoretical and empirical literature. Moreover, apart from the quantitative variables, two qualitative variables have also been considered through the use of dummy variables. The Cobb–Douglas, Transcendental logarithmic and Simultaneous equations models have been used for the study.

The result reveals that the partial elasticities of the per-capita gross domestic product (PCGDP) of India with respect to FDI, mobile density (MD) and internet density (ID) are 0.074, 0.024 and 0.036, respectively. The positive and significant coefficient of the interaction among FDI, MD and ID in the estimation of the transcendental logarithmic function indicates the importance of ICT infrastructure in extracting the best out of FDI (the coefficient is 0.011 for the model without any control variables and it is 0.005 with control variables).

The findings of this study are more reliable as the latest available data have been analysed through the appropriate econometric models. This study will be useful for the policymakers in the formulation of policies with regard to foreign capital and digitalisation.

This paper aims to test whether the extent of compliance with International Financial Reporting Standards (IFRS) 7 requirements is value relevant and whether it influences the value relevance of the firm's accounting information (book value of shareholders' equity and net income).

The sample for this paper consists of 288 financial institutions listed on the Toronto Stock Exchange (TSX) from 2016 to 2019. Panel regressions have been used in this study.

The findings reveal that compliance with IFRS 7 is positively associated with the firm's market value. After making a classification between high-compliance and low-compliance companies, the authors' results indicate that the compliance level is positively associated with the value relevance of net income. Surprisingly, when examining the value relevance of financial instruments disclosures (FID) supplied after the adoption of IFRS 9, the authors find that book values of shareholders' equity and earnings are not more value relevant in the post-IFRS 9 period.

Given that the authors' analysis has been restricted to the Canadian setting, the regression results might not be generalized for other countries with different capital markets features.

The authors' findings point out that FID can affect investors' decisions as well as their confidence in the companies in which they invest. Hence, the regulatory bodies should gear more efforts to ensure high-compliance levels.

To the best of the authors' knowledge, this research is among the first attempts to investigate whether the new FID (after the adoption of IFRS 9) improves the firm disclosure quality and enhances the value relevance of accounting information.
