Graph neural network‐based attack prediction for communication‐based train control systems
Abstract The Advanced Persistent Threats (APTs) have emerged as one of the key security challenges to industrial control systems. APTs are complex multi‐step attacks, and they are naturally diverse and complex. Therefore, it is important to comprehend the behaviour of APT attackers and anticipate the upcoming attack actions.

Review of Catenary Icing on High‐Speed Railways: Characteristics, Impact and Countermeasures
ABSTRACT The pantograph–catenary system (PCS) is the only path for electrified railway trains to acquire energy. Catenary icing during winter is a common natural phenomenon, which usually leads to the deterioration of the current quality and severely affects the operational safety of trains.

Lobbying and Political Risk Disclosure: Do Socially Responsible Firms Voluntarily Disclose More?
Abstract Drawing on theories of strategic communication, legitimacy, impression management and moral capital, this study investigates whether firms use political risk disclosure to offset negative perceptions associated with corporate lobbying. Using a sample of 10,120 observations from 1362 US firms between 2002 and 2018, we find that firms with ...

Green Hunter or Green Detractor? Strategic Orientations and Green Revenues
Abstract We bridge a research gap concerning whether varying strategic orientations can be aligned with the transition to greener business practices. Drawing on resource‐based theory and stakeholder theory, we investigate how growth‐ and profit‐oriented strategic orientations shape firms’ capacity to generate green revenues that integrate economic ...
