Symbolic Versus Substantive ESG Practices: A Systematic Review and Integrative Framework

Corporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT ESG reporting is widespread, but symbolic commitments do not always reflect substantive practices. This study conducts a systematic literature review of 62 empirical articles published between 2021 and 2025 to synthesize the main determinants and consequences of this disclosure–performance misalignment in ESG reporting (commonly referred to as

Extending the hyper‐logistic model to the random setting: New theoretical results with real‐world applications

Mathematical Methods in the Applied Sciences, EarlyView.
We develop a full randomization of the classical hyper‐logistic growth model by obtaining closed‐form expressions for relevant quantities of interest, such as the first probability density function of its solution, the time until a given fixed population is reached, and the population at the inflection point.

Spatial Dynamics of Tourism Sustainability in EU Member States

Sustainable Development, EarlyView.
ABSTRACT This study introduces a synthetic indicator of tourism sustainability for the EU, bridging the gap between institutional monitoring and academic research. By applying the PROMETHEE II method to rank the 27 Member States in 2019 and 2023, the research transforms static data into a dynamic roadmap of post‐pandemic recovery. The findings reveal a
