Equity ownership structure and timeliness of financial reporting: Evidence from the listed financial companies in Nigeria
No full textYesThe study investigates the effects of equity ownership structure, which encompasses government, foreign institutional, managerial (both foreign and domestic directors), and individual foreign ownership, on the FRL (financial reporting lag) of financial companies listed on the Nigerian Exchange Group (NGX). The sample comprises 48 financial companies, including banks and insurance firms, listed on the NGX over ten financial years (2012–2021), amounting to 450 firm-year observations. The study employed three distinct measures of FRL (total delay, management delay, and audit delay). The results indicate that the mean audit and management delays do not differ among the sampled banks; however, audit delays are more pronounced than management delays in insurance companies. Despite the shorter regulatory timeframe, the banks demonstrate greater timeliness than insurance companies. The findings also reveal that foreign institutional ownership significantly impacts all three FRL constructs, suggesting it reduces FRL. Conversely, domestic managerial ownership has a notable adverse effect on management and total delays. It was also discovered that government ownership reduces audit delays (a negative relationship) but extends management delays (a positive relationship). The results remained robust when two alternative measures were utilized to evaluate the timeliness of financial reporting

It is essential to comprehensively evaluate IoT systems' security features to comprehend and successfully address security risks. This article offers an in-depth exploration of quantifying IoT security, examining some of the existing assessment models, associated challenges in security quantification, and potential avenues for advancement. The principal contribution of this article lies in providing an overview of the current state of IoT security quantification analysis, delineating prominent challenges, and proposing prospects for addressing them
Environmental Impacts and Energy Transition in Chinese Logistics: An N-Spheres Multi-Criteria Decision-Making
No full textThis paper presents the N-Spheres geometrical concept as a novel Multi-Criteria Decision-Making (MCDM) model to evaluate environmental impacts and energy transitions in logistics transportation across Chinese provinces. By incorporating data such as truck quantities, logistics network mileage, fixed asset investments, and energy consumption, the study creates an n-dimensional framework to assess logistics systems' energy efficiency and CO2 emissions. The adapted N-Spheres model, originally from theoretical mathematics and computer science, is applied to analyze trade-offs, criterion elasticity, and contributions to overall performance, linking economic activities to environmental impacts. The findings reveal significant regional disparities in Environmental, Energy, and Transport Logistics (EETL) performance, with coastal regions typically outperforming inland areas. Higher freight transport volumes and logistics network mileage enhance performance, while CO2 emissions and energy consumption highlight the need for improved environmental management. Overall, the results indicate a trend towards better logistics performance over time.The full text will be available at the end of the publisher's embargo: 13th Dec 202
The 'Protection' of Women and 'the Vulnerable' in Contemporary India
No full textYesThis chapter seeks to explore the “protection” of perceived “vulnerable” populations (women, Dalits and Adivasis) by proponents and sympathizers of the Hindutva ideology, a cultural nationalist ideology prominent in contemporary India. These communities are portrayed as being vulnerable and, therefore, needing to be protected from the Muslim and Christian ‘Threat’. In contemporary India, this ‘protection’ has taken multiple forms including moral policing, vigilante violence, and legislation. This chapter explores these dynamics with a particular focus on the southern Indian state of Karnataka. The chapter draws on a range of data including an analysis of newspaper coverage in English and Kannada (the state language of Karnataka), postings on X (previously known as Twitter) and civil society reports
Bayesian DEA Framework for Market Power and Efficiency Analysis in Banking Operations
No full textYesThe accurate measurement of marginal costs and market power is a persistent challenge in production economics and operations research, particularly within the banking sector. This study addresses this problem by proposing a Bayesian likelihood-based approach to estimate the Lerner index under multiple inputs and outputs, extending the nonparametric Data Envelopment Analysis (DEA) methods of Fukuyama and Tan (2022a) with statistical inference. Using data from 36 Chinese banks (2011–2018), the results reveal that market power in loans is generally higher and more stable compared to securities, with significant variations across different bank ownership types. For instance, city banks demonstrate the highest market power in loans, while state-owned banks exhibit the lowest. Efficiency analysis indicates volatility across all bank types, with no clear efficiency patterns. These findings have critical policy implications, emphasizing the need for targeted strategies to enhance market power and efficiency sustainably. For example, rural, city, and joint-stock banks should focus on staff development in non-traditional banking, while state-owned banks could benefit from operational cost reductions. The proposed methodology also provides a robust framework for future studies on market power and efficiency in diverse industries
Climate Risk Assessment at Chinese Provinces: A Novel Criteria and Context Decomposition for Trade-Off Weighting (CCDTW) Approach
No full textYesThis paper introduces the Criteria and Context Decomposition for Trade-Off Weighting (CCDTW) methodology, a novel multi-criteria decision-making (MCDM) approach for assessing and ranking climate risks across Chinese provinces. Using a non-balanced panel dataset of 1457 observations, the CCDTW integrates QR decomposition to decorrelate climate risk criteria—extreme low and high temperatures, rainfall, and drought—and socio-economic contextual variables, capturing trade-offs and relative importance among them. Weighted trade-off coefficients are derived to construct a Climate Risk Index (CRI), which facilitates the ranking and benchmarking of provinces over time. The results reveal heterogeneous patterns of climate risk across regions, with increasing trends in extreme temperatures and rainfall in recent years. The CRI indicates that employment, power generation, and population access to natural gas are the primary drivers of climate risk, highlighting the trade-offs between economic welfare and climate mitigation. This framework provides policymakers with actionable insights to design region-specific and time-sensitive climate risk management strategies
Experiences, impacts, and requirements of synchronous video consultations between nurses, allied health professionals, psychological therapists, and adult service-users: A review of the literature
No full textYesBackground: Telemedicine is increasingly used within healthcare worldwide. More is known about its efficacy in treating different conditions and its application to different contexts than about service-users’ and practitioners’ experiences or how best to support implementation.
Aims: To review adult service-users’ experiences of synchronous video consultations with nurses, allied health professionals and psychological therapists, find out how consultations impact different groups of service-users and identify requirements for the conduct of VCs at individual, organisational, regional, and national levels.
Method: CINAHL, Embase, Medline, PsycINFO Scopus were searched for papers published between 01/01/2018 and 19/03/2021. One reviewer independently reviewed citations and a second reviewed those excluded by the first reviewer, in a liberal accelerated approach. Quality assessment was undertaken using the Mixed Methods Appraisal Tool and data were synthesised narratively.
Results: 65 papers were included. Service-users’ experiences of video consultations ranged from feelings of connection to disconnection and ease of access to challenges to access. Many service-users were excluded from video consultation services or research, based on mental health, language or access to technology. Requirements at individual practitioner level included providing clear orientation and ongoing technical support and developing technical and relational skills. At organisational levels, requirements involved making technology available to users through equipment loan or service models such as hub-and-spoke; planning services carefully; integrating them within organisational systems; and assuring security. Regional and national requirements related to inter-organisational co-operation and developing functionality.
Conclusion: To support safe and equitable video consultation provision, we recommend: (1) providers and researchers consider carefully how to maximise participation, for example through more inclusive consent processes; (2) sharing video consultation user guides and technical support documentation; and (3) continuing professional development for practitioners, focusing on the technical and relational skills that service-users value, such as the ability to convey empathy online
Corporate social responsibility gap and firm value: The moderating role of trust
No full textNoFocusing on a firm’s imbalance between internal and external stakeholder orientations, we propose that the impact of this stakeholder disparity on the firm’s market value depends on country-level trust. Integrating sociology research on societal trust with strategy research on corporate social responsibility (CSR), we argue that firms in countries with higher outgroup trust experience more negative effects from gaps between internal and external CSR actions. In contrast, in countries with greater ingroup trust compared to outgroup trust, the negative impact of the CSR gap on firm value is mitigated. Our empirical analysis of firms across 46 countries supports our predictions. Our study is the first to theoretically and empirically demonstrate the multilevel social capital framework on firm value throughout the cross-national investigation of the interactive influence of firm-level stakeholder orientations and country-level trust radius
