The purpose of this paper is to better understand how consumers perceive and process danger in American football and why they continue to enjoy watching the sport given society’s increased understanding of the danger to the athletes.

Two studies, one lab study with eye-tracking (N = 152) and one survey study (N = 444), were conducted. Study 1 examines how the perception of danger associated with football mediates the relationship between exposure to violent or nonviolent video clips and enjoyment of watching video clips. Study 2 examines how device type and screen resolution influence perceptions of danger associated with football.

Findings support the role that perceived danger plays in sport viewing enjoyment. The results are in keeping with reversal theory where individuals have a protective frame that allows them to experience negative emotions (e.g. anxiety) as positive (e.g. excitement). The research also shows that for larger devices, the perception of danger associated with football is significantly influenced by high resolution.

The work, through considering the way consumers experience sport, questions societal tolerance for entertainment that is dangerous to sport participants.

The findings of this work corroborate past research that has found that consumers of sport do enjoy danger for athletes in their viewing experience. Reversal theory is utilized to explain how negative emotions are experienced as positive. The work extends past findings by showing that the characteristics of the device used (large size and high resolution) during sport viewing influence perceptions of danger.

In the last few years, environmental issues have become a matter of survival. In this sense, e-waste management is among the major problems since it may be a way of mitigating mineral depletion. In this context, the literature lacks e-waste supply chain studies that systematically map supply chain challenges and risks concerning material recovery.

Given this context, the authors' paper conducted a systematic literature review (SLR) to build a framework to identify the constructs of e-waste supply chain risk management.

The paper revealed the theoretical relationship between important variables to achieve e-waste supply chain risk management via a circular economy (CE) framework. These variables include reverse logistics (RL), closed-loop supply chains (CLSC), supply chain risk management, supply chain resilience and smart cities.

The literature contributions of this paper are as follows: (1) a complete list of the risks of the e-waste supply chains, (2) the techniques being used to identify, assess and mitigate e-waste supply chain risks and (3) the constructs that form the theoretical framework of e-waste supply chain risk management. In addition, the authors' results address important literature gaps identified by researchers and serve as a guide to implementation.

In the context of fire incidents within buildings, efficient scene perception by firefighting robots is particularly crucial. Although individual sensors can provide specific types of data, achieving deep data correlation among multiple sensors poses challenges. To address this issue, this study aims to explore a fusion approach integrating thermal imaging cameras and LiDAR sensors to enhance the perception capabilities of firefighting robots in fire environments.

Prior to sensor fusion, accurate calibration of the sensors is essential. This paper proposes an extrinsic calibration method based on rigid body transformation. The collected data is optimized using the Ceres optimization algorithm to obtain precise calibration parameters. Building upon this calibration, a sensor fusion method based on coordinate projection transformation is proposed, enabling real-time mapping between images and point clouds. In addition, the effectiveness of the proposed fusion device data collection is validated in experimental smoke-filled fire environments.

The average reprojection error obtained by the extrinsic calibration method based on rigid body transformation is 1.02 pixels, indicating good accuracy. The fused data combines the advantages of thermal imaging cameras and LiDAR, overcoming the limitations of individual sensors.

This paper introduces an extrinsic calibration method based on rigid body transformation, along with a sensor fusion approach based on coordinate projection transformation. The effectiveness of this fusion strategy is validated in simulated fire environments.

The study aims to empirically examine the effect of board industry expertise on environmental, social and governance (ESG) strategy, and the mediating role of environmental innovation.

Using an unbalanced sample of 341 publicly traded Italian non-financial firms and data collected from multiple sources over the period 2017–2021, this study applies single-mediator models via ordinary least squares regressions.

Results indicate that directors’ industry expertise improves the corporate orientation toward sustainability strategy that is reflected in ESG objectives. This effect is partly mediated by a greater level of environmental innovation.

The article suggests regulators to promote eco-innovation-friendly investment initiatives due to their value in advancing corporate sustainability strategies.

The research fills a gap in the literature that has never explored the effect of board industry expertise on sustainability-related outcomes. Moreover, it advances the debate on the implications of board human capital by assessing its influence on ESG strategy and environmental innovation.

Corporate Social Responsibility (CSR) reporting has been widely accepted as a vital tool for communicating with stakeholders on a range of social, environmental, and governance issues, but how companies define, interpret, apply, integrate, and communicate their CSR efforts and impacts in corporate reporting is anything but a straightforward task. The purpose of this chapter is to explore the concept of materiality in CSR reporting and demonstrate practical examples of good CSR and Sustainable Development Goals (SDGs) reporting practices. We chose the aviation industry because of its economic relevance, constant growth, and future expected changes in the aftermath of COVID-19. In addition, airlines affect many of the SDGs directly and indirectly with contending results. This chapter is timely because of the growing willingness by companies to integrate CSR and environmental, social, and governance (ESG) thinking into the corporate strategy and business operations using materiality assessment and enhancing their competitive advantage and ability to maintain long-term value and because ESG and ethical investing have become part of the mainstream investing. Thus, this chapter contributes to an understanding of the wide range of existing and new reporting frameworks and regulations and reinforces the importance of discussing how this diversity of approaches can affect the work toward worldwide comparability of CSR and sustainability reporting.

This study aims to identify comfort food (CF) consumption and its associated factors during the pandemic period. The study also involves an online survey conducted five months after the quarantine started in Brazil.

Data on lifestyle, eating habits and anthropometric data were collected before and during the pandemic, and the differences in these habits were analyzed. Univariate and multivariate logistic regression models were performed to identify predictors of CF consumption by gender.

A total of 1,363 individuals were included in the sample, with a median age of 31 years old, of whom 80.3% were women. Since individuals were free to respond about the food consumed without predetermined categories, it was possible to carry out a faithful assessment of the occurrence of this behavior. At the same time, allowing the subjectivity and symbolism inherent to the concept of CF to be embraced. CF consumption was present for 54%, with “sweets” being the most mentioned group by both genders. The factors associated with CF consumption in women during the pandemic were increased snacking, increased bread, candies and alcoholic beverage intake, increased time spent at work, worsened sleep quality, reduced meals, perceived stress (PS), emotional eating (EE), age and increased frequency of meat intake. In men, the predictors for CF consumption were remote full-time work/study, PS, EE and early waking time. For both genders, CF consumption during the pandemic period was associated with PS and EE.

This study provides an important overview of the possible contributions of the pandemic on behaviors and food choices related to the consumption of CF in Brazilians. This information is valuable to support further studies to investigate and treat the impacts of the pandemic on lifestyle, eating habits and behavior, mental health and other factors in the postpandemic period.

Financial institutions have a role in harmonising economic purposes with environmental and social purposes through transmission mechanisms whereby the institutions provide channels to promote socially and environmental desirable activities. This study explores the sustainability criteria disclosed at firm-level corporate social responsibility reports for the purpose of providing direction for financial institutions committed to enhancing the contribution to sustainability objectives.

The Delphi Method and the Decision-Making Trial and Evaluation Laboratory (DEMATEL) system have been employed to systematically analyse the opinions of 15 experts regarding the operation of the 7 Taiwanese financial institutions listed on the Dow Jones Sustainability Index in 2019 with respect to the capacity to affect sustainability objectives.

The findings reveal a high prominence level for corporate governance, law compliance, risk management and occupational safety and health, representing amongst the sustainability criteria considered. This suggests that financial institutions may benefit from focussing resources on these areas, starting with corporate governance, when considering means for enhancing the sustainability performance.

The study is limited by the small number of financial institutions available in Taiwan which suggests that further research could be directed towards a larger sample of financial institutions, say by international comparison, expanding the range of industries studied or the inclusion for additional sustainability indicators.

Overall, the study has shed light on Taiwan's financial institutions' capacity to contribute to sustainable practices which is an area that has not been extensively investigated. This study may have useful implications for financial institutions in Taiwan.

The authors also recognise other factors that are likely to contribute to social impacts. These include human capacity building and development, information security, green procurement, green building and climate-related financial products.

This study fills the gap by providing useful insights for a better understanding of sustainable development in financial institutions by promoting sustainability practice in general. The authors' analysis will assist decision-makers in identifying and prioritising the driving factors and thus adopting suitable strategies to strengthen sustainability performance.

Applying universal ownership theory and drawing on a multiplecase study design, this study aims to analyze what drives institutional investors to engage with government entities and what challenges they find in the process.

The authors relied on document analysis and conducted 12 semi-structured interviews with representatives from asset owners, asset managers, investor associations and academia.

The authors identify a trend where investors conduct policy engagement to fulfill their fiduciary duty, improve investment risk management and create an enabling environment for sustainable investments. As for engagement challenges, investors report the longer-term horizon, a perceived limited influence toward governments, the need for capacity building for investors and governments, as well as the difficulty in accessing government representatives.

This research contributes to filling a gap in the literature on this new form of investor activism, as a growing number of investors engage with sovereign entities on environmental, social and governance issues.

Supply chain revamping (SCR) is an important strategy for firms to improve their supply chain operations in a rapidly changing environment. The purpose of this study is to shed light on the impact of SCR on shareholder value.

Based on Signaling Theory and 184 SCR announcements published by US-listed firms from 2013 to 2018, this study employs event study methodology and empirically examines three issues: Antecedents of SCRs; Primary purposes and actions of SCRs; In addition to the impact of SCRs on shareholder value using stock returns, we also examined the factors that can influence the extent of stock returns.

Firstly, our results indicate that SCRs are primarily driven by firms’ poor prior performance, CEO turnover and external control threats (ECTs). Secondly, the stock market favors SCRs aiming to meet customer needs and those accomplished through network remodel. However, the market reacts negatively to SCRs aiming at cutting costs, improving poor performance, and those implemented through network trim. Finally, the cross-sectional analysis indicates that shareholders prefer firms operating in more competitive or faster-growing industries and those adopting an expansionist strategy than those adopting a streamlining strategy.

Our study provides managers with valuable insights into when firms can benefit from initiating SCRs not only by examining the purposes and actions of SCRs but also by examining the industry- and strategy-specific moderators. Our study illuminates the conditions under which SCR will positively affect shareholder value. Additionally, this study contributes to the existing literature by deepening the understanding of the impact of supply chain decisions on firm performance and identifying the marginal conditions under which the stock market will react positively to SCR announcements.

In this study, an indoor sensor information fusion positioning system of the quadrotor unmanned aerial vehicle (UAV) was investigated to solve the problem of unstable indoor flight positioning.

The presented system was built on Light Detection and Ranging (LiDAR), Inertial Measurement Unit (IMU) and LiDAR-Lite devices. Based on this, one can obtain the aircraft's current attitude and the position vector relative to the target and control the attitudes and positions of the UAV to reach the specified target positions. While building a UAV positioning model relative to the target for indoor positioning scenarios under limited Global Navigation Satellite Systems (GNSS), the system detects the environment through the NVIDIA Jetson TX2 (Transmit Data) peripheral sensor, obtains the current attitude and the position vector of the UAV, packs the data in the format and delivers it to the flight controller. Then the flight controller controls the UAV by calculating the posture to reach the specified target position.

The authors used two systems in the experiment. The first is the proposed UAV, and the other is the Vicon system, our reference system for comparison purposes. Vicon positioning error can be considered lower than 2 mm from low to high-speed experiments. After comparison, experimental results demonstrated that the system could fully meet the requirements (less than 50 mm) in real-time positioning of the indoor quadrotor UAV flight. It verifies the accuracy and robustness of the proposed method compared with that of Vicon and achieves the aim of a stable indoor flight preliminarily.
