Substantive or Symbolic? Analyzing the Quality of Impact Reports in Italian B‐Corps Through Legitimacy Theory

open access: yesCorporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT Sustainability reporting has become increasingly compelling, particularly among hybrid organizations such as B‐Corps, which seek to balance profit and purpose and are required to publish annual Impact Reports. This study assesses the completeness of disclosed information in the 2022 Impact Reports of 74 Italian B‐Corps, drawing on legitimacy ...

Study on the failure mechanism of the shield excavation face in the sandy cobble stratum under different buried depths

open access: yesDeep Underground Science and Engineering, EarlyView.
Abstract One of the significant challenges faced in shield tunnel construction is the risk of collapse resulting from abrupt changes in soil conditions in advance of the working face, particularly within the sandy cobble stratum. This study aims to effectively manage these sudden variations and to further investigate the failure mechanisms associated ...

Impact Analysis of Demand Management on Runway Configuration in Metroplex Airports

open access: yesIEEE Access, 2020
Congestion in airports and metroplexes is increasingly becoming a key bottleneck in the global air transport system. It is largely due to inefficient utilization of runway resources and its consequences of imbalance between demand and capacity.

Analytical Floor Response Spectra for Performance‐Based Seismic Design of Non‐structural Elements in Reinforced Concrete Frame Buildings

open access: yesEarthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Damage to non‐structural elements significantly impacts the seismic performance of buildings in terms of economic and functionality losses. Consequently, performance‐based seismic design of non‐structural elements has become a key pillar of a comprehensive building‐seismic resilience strategy, for instance, through loss‐targeted earthquake ...
