On the compressive strength of weak snow layers of depth hoar

Journal of Glaciology
We determined the compressive strength of weak layers of faceted crystals and depth hoar using artificially grown samples with a wide range of microstructural morphologies in a cold laboratory setup.

Climate Change Risks and Customer Concentration: Evidence From US‐Listed Firms

Business Strategy and the Environment, EarlyView.
ABSTRACT While prior studies have investigated climate risks in supply chains, customer ESG pressures, and shared climate exposure, this paper is, to the best of our knowledge, the first to provide direct empirical evidence on the relationship between climate change risks and firms' customer concentration.

Numerical study of fracture arrest on snow cover [PDF]

Fracture and Structural Integrity, 2010
Under the hypothesis of a perfectly brittle phenomenon, avalanche triggering can be investigated numerically by means of Linear Elastic Fracture Mechanics (LEFM).

The mechanics of snow friction as revealed by micro-scale interface observations

Journal of Glaciology, 2018
The mechanics of snow friction are central to competitive skiing, safe winter driving and efficient polar sleds. For nearly 80 years, prevailing theory has postulated that self-lubrication accounts for low kinetic friction on snow: dry-contact sliding ...

From Green Governance to Biodiversity Strategy: The Role of Environmentally Experienced Directors in Chinese Firms

Business Strategy and the Environment, EarlyView.
ABSTRACT This study investigates how directors with environmental protection (EP) backgrounds influence corporate biodiversity concern (BIO) among Chinese A‐share listed firms from 2008 to 2023. Drawing on Upper Echelons Theory, we argue that directors' environmental expertise shapes firms' biodiversity strategies.

Observing the effect of morphology on the elastic properties of new snow using a non-contacting laser ultrasound system

Journal of Glaciology
Quantifying micromechanical and microstructural properties of snow is crucial, as they control bulk thermal, electrical and mechanical properties.

Physics of Skiing: The Ideal-Carving Equation and Its Applications

, 2003
Ideal carving occurs when a snowboarder or skier, equipped with a snowboard or carving skis, describes a perfect carved turn in which the edges of the ski alone, not the ski surface, describe the trajectory followed by the skier, without any slipping or ...

Sustaining Circular Innovation Under Volatile Market Conditions: The Critical Role of Industry Platforms

Business Strategy and the Environment, EarlyView.
ABSTRACT While industry platforms are widely recognized as enablers of circular innovation, we still know little about how they evolve to scale and sustain innovation as economic conditions tighten and circular economy funding schemes become more selective.

A Two-Threshold Model for Scaling Laws of Non-Interacting Snow Avalanches

, 2004
The sizes of snow slab failure that trigger snow avalanches are power-law distributed. Such a power-law probability distribution function has also been proposed to characterize different landslide types.
