Interdisciplinary modelling in support of people-centred transitions: Forecasting citizen adoption of rooftop PV systems under alternative sociopolitical future-world evolutions

Rooftop photovoltaic (PV) systems are central to decentralised solar transitions in Europe, yet their diffusion depends on more than technical potential, technology costs, or the formal design of support schemes. As Member States move from guaranteed remuneration mechanisms towar...

Leveraging artificial intelligence for sustainable development and policy integration in the shipping industry

Shipping is a critical industry for global trade but is associated with environmental externalities like air, underwater noise, and light pollution. Transitioning to a sustainable future requires optimizing propulsion systems, which currently suffer from fossil fuel reliance and...

One‐Sided Combined Control Charts for Monitoring a Shifted Exponential Process in the Case of Individual Observations

ABSTRACT The shifted (or two‐parameter) exponential distribution is a well‐known flexible probability model for skewed data, such as failure times or survival times due to its two‐parameter representation. Control charts for monitoring a process that is modeled according to a shi...

Dynamic defense strategies for cyber-physical systems using Stackelberg games and deep reinforcement learning in discrete and continuous time

Abstract As cyber threats to power grid infrastructures escalate, the urgency of understanding how to protect cyber-physical systems (CPS) has never been greater. These systems, which integrate physical processes with digital control, are increasingly susceptible to sophisticated...

Examination of the Risk Spillover Among the European Tourism and Hospitality Sectors: How COVID-19 Exerted Its Influence in Its Era?

This paper explores the effects of COVID-19 pandemic-related uncertainty on the European tourism subsectors, including airlines, hotels, and restaurants. Daily returns connectedness quantifies risk-sharing patterns in the tourism and hospitality industry and links them to measure...

Exploring the connection between coding habits and cognitive styles in malware developers

Malware research primarily studies the results, the methods, and the impact. Even from an offensive security perspective, what is examined is the method, not the development strategy of the offender. This study investigates the behavioral signatures and coding patterns embedded i...

Online Negative Reviews and Complaints in Healthcare and Dentistry: A Narrative Review of Patient Experiences

Background: The widespread use of online review platforms has transformed how patients evaluate healthcare providers and has created a valuable source of patient-generated feedback on healthcare quality. Negative online reviews provide valuable insights into patient experiences a...

Dynamic threshold effects of corruption on tourism demand: A nonlinear relationship

This note investigates the complex relationship between corruption and tourism demand, employing a dynamic panel threshold model in the spirit of Seo and Shin (2016). Using a panel dataset of international tourism destinations over the period 2008–2022 and two corruption measures...
