Managing Biodiversity Disclosure in Global Firms: How Culture, Institutions and Risk Shape Corporate Reporting

Business Strategy and the Environment, EarlyView.
ABSTRACT This study examines the drivers of biodiversity disclosure and the interplay between firm strategies and national institutions in shaping transparency. Using a global panel of 4703 firms across 40 economies from 2013 to 2022, we integrate differentiation, signalling and institutional perspectives to explain variation in reporting behaviour ...

GROUNDING GRID PERFORMANCE OF SUBSTATION IN TWO LAYER SOIL- A PARAMETRIC ANALYSIS [PDF]

, 2014
During ground faults, fault current flows in the ground which results in potential gradient and ground potential rise (GPR). The potential gradient affects the safety of operating person due to step and touch voltage and GPR affects the insulation of ...

Associating Borehole Radar Imaging with Petrophysical Properties for a Mud-Contaminated Reservoir [PDF]

, 2019
In the phase of oil drilling, mud filtrate penetrates into porous formations and alters the pore fluid properties. This complicates well logging exploration, and inevitably gives rise to shift in reservoir estimation.

Cationic Sulfonium‐Based Tripodal Ligand and Its Rh(I) Complexes

Chemistry – A European Journal, EarlyView.
We report a cationic EP3‐type tripodal ligand based on an aromatic sulfonium cation (E = S+) along with a series of its Rh(I) complexes. Structural, spectroscopic, electrochemical, and computational analyses of these complexes compared to isostructural analogs (E = Si− or P) reveal pronounced electron density depletion at Rh in the sulfonium congener ...
