- Climate change and human migration: managing the cascade effects initiated by natural disastersPublication . Almeida, Victor; Ricci, Paolo F.The potential links between climate change, human migration and conflict have been receiving an increasing amount of attention since the turn of the century. Up-to-date reports that address the most recent understanding of climate change and environmental hazards indicate that humans have undeniably contributed to the rising global temperature and will continue to do so if lower pollution thresholds are not maintained. While this enacts a multitude of physical, biological, chemical, and societal changes, it is imperative to analyze and address the impact of climate change on human migration trends. Human migrants face several types of problems ranging from environmental issues related to climate change (sea-level rise, more frequent and intense storms and floods, drought, wildfires, etc.), to conflicts from physical migration into neighboring towns, cities, regions, or countries. These types of physical migration that are climate change driven, which can be referred to as “adaptation migration” can be capable of snowballing from a human-to-environment issue into a human-to-human conflict; usually involving some type of violence or political discrimination/persecution. The aim of this study is to analyze how climate change is impacting human migration trends, the possible percolating effects that can result from human migration, and how these factors have influenced and will continue to influence governments and governance in the coastal area. The information in this report will be able to provide a greater understanding of adaptation migration through the use of differential equations, how these trends can be modeled, and how Game Theory can be used as a strategic tool for policymakers moving forward.
- Examining identity and perceived risk on technology acceptance and behavioural intentions of fans: an extended TAM perspectivePublication . Shuya, Zhao; Ribeiro, Tiago; Almeida, VictorPurpose – The rise of digital innovations in the sports industry has led to the growing adoption of fan tokens, offering sports organisations new ways to engage with their fans. As these digital assets gain traction, understanding the factorsthat influence their acceptance becomesincreasingly critical. Thus, thisstudy usesthe Technology Acceptance Model to explore the roles of fan identity and the perceived risk in shaping fan token acceptance and aims to examine their effect on the behavioural intentions of football fans. Design/methodology/approach – Data were gathered from a sample of football fans (n 5 360) representing eight Brazilian clubs that issue official fan tokens through the Socios.com platform. Structural equation modelling was employed to test the hypothesized relationships within the proposed framework with bootstrapping techniques applied to assess the robustness of the estimates and examine the mediating effects of key variables on behavioural intentions. Findings – The results highlight the key role of TAM in predicting fan token adoption. Technological acceptance emerged as a strong predictor of both word-of-mouth communication and fan purchase intentions. Fan identity demonstrated a significant positive influence on fan token acceptance and purchase intention. Moreover, fan token acceptance was found to mediate the relationship between fan identity and behavioural intentions, indicating that fans with strong identification are more likely to adopt tokens from their sports clubs. Originality/value – This study advances theoretical understanding by incorporating fan identity, trust and perceived risk into the extended TAM framework. Our findings highlight the critical importance of trustbuilding strategies and effective risk mitigation in promoting fan adoption of technology and strengthening their behavioural intentions. The fan token industry should recognize the well-established and mediating role of technological acceptance while strengthening trust and leveraging fan identity to build deeper, value-driven connections.
