Secure and Private Over-the-air Federated Learning: Biased and Unbiased Aggregation Design See

Over-the-air federated learning (OTA-FL) presents a promising paradigm that improves the efficiency of local update aggregation by leveraging the superposition property of wireless multiple access channels (MACs). However, it faces significant security and privacy concerns that demand careful consideration...

Investor Sentiment, Anchoring, and Momentum Returns. See

We hypothesize that anchoring enhances the disposition effect, while investor sentiment likely strengthens (or weakens) this effect when news contradict (or align with) the prevailing investor sentiment. This study examines the profitability of momentum strategies based on past return performance ...

Momentum Returns and Corporate Governance See

We hypothesize that corporate governance affects, first, how a firm is perceived by investors in terms of risk, transparency, and valuation and, second, investors’ decisions to buy/sell past winning/losing stocks during good and bad times. Implementing momentum strategies on portfolios ...

Residual Income Valuation and Stock Returns. Evidence from a Value-to-Price Investment Strategy See

This paper contributes to the accounting and asset pricing anomalies literature by investigating the performance of value-to-price strategies, and the relationship between value-to-price ratio and several risk proxies. If the value-to-price ratio successfully predicts future returns at stock level, we...

US Futures Markets Interconnectedness During Crisis Periods See

This study contributes new empirical evidence on the interconnectedness of crude oil, precious metals, and financial futures during crisis/non-crisis periods. Dynamic spillovers from US to Europe and Asian futures markets are also examined. Empirical results show a significant and changing r...

Digital twin-optimised repurposing of spent mushroom substrate into circular bio-based composites See

The global mushroom industry generates over 60 million tons of spent mushroom substrate (SMS) annually, presenting both an environmental challenge and an opportunity for sustainable material development (Grimm et al., 2018) ...

Predictors of waste management behaviours in coastal communities in Indonesia: The role of community attachment and environmental concern See

The global challenge of marine plastic pollution requires systemic change in our relationship with plastic. The current linear plastic economy must transition to a sustainable circular model, but is hindered by behavioural change difficulties, particularly in coastal regions facing resource limit...

Barriers to Mainstream Adoption of Circular Packaging in Indonesia See

Achieving the mainstream adoption of circular packaging is essential for mitigating the environmental impacts of plastic waste. Its widespread adoption, however, remains hindered by significant user barriers. This study investigates the barriers to user adoption of upstream packaging solutions in ...

Developing a Novel Adaptive Double Deep Q-Learning-Based Routing Strategy for IoT-Based Wireless Sensor Network with Federated Learning See

The working of the Internet of Things (IoT) ecosystem indeed depends extensively on the mechanisms of real-time data collection, sharing, and automatic operation. Among these fundamentals, wireless sensor networks (WSNs) are important for maintaining a countenance with their many distributed Sens...
