Assertion: Just One Way to Take It Back [PDF]

open access: yes, 2016
According to Jonathan Kvanvig, the practice of taking back one’s assertion when finding out that one has been mistaken or gettiered fails to speak in favour of a knowledge norm of assertion.

Decline in Seasonal Snow during a Projected 20-Year Dry Spell

open access: yesHydrology, 2022
Snowpack loss in midlatitude mountains is ubiquitously projected by Earth system models, though the magnitudes, persistence, and time horizons of decline vary.

Modeling of the Snowdrift in Cold Regions: Introduction and Evaluation of a New Approach

open access: yesApplied Sciences, 2019
Unbalanced, or non-uniform, snow loads caused by snow drifting or sliding in cold regions with heavy snowfalls, can be a serious problem for the building industry. However, the methods for predicting snow distribution still need to be improved.

Uncertainty Analysis of Snow Depth Retrieval Products over China via the Triple Collocation Method and Ground-Based Measurements

open access: yesRemote Sensing
Snow depth is a crucial variable when assessing the hydrological cycle and total water supply. Therefore, thorough and large-scale assessments of the widely used gridded snow depth products are highly important.

Winter Tourism and Climate Change in the Alps: An Assessment of Resource Consumption, Snow Reliability, and Future Snowmaking Potential

open access: yes, 2011
The winter tourism industry is facing considerable challenges with climate change; it is increasingly responding with investments in snowmaking facilities. We present a study on 3 tourism destinations in the Swiss Alps that addressed resource consumption

Snow Tracking and Trapping Harvest as Reliable Sources for Inferring Abundance: A 9-year Comparison [PDF]

open access: yesNortheastern Naturalist, 2015
Abstract Trapping harvest and snow tracking are frequently used to infer population dynamics, yet there have been few evaluations of these indices. We developed population indices for Martes americana (American Marten), Mustela spp. (weasels), and Tamiasciurus hudsonicus (American Red Squirrel) from 9 years of snow-tracking data in eastern Canada.

Anti‐Slip Material‐Based Strategies and Approaches

open access: yesAdvanced Materials Technologies, EarlyView.
This review highlights the principle mechanisms of slipping at the microscale, linking contact mechanics with a friction behavior model for surface interfaces. Main strategies to develop anti‐slip properties to the surfaces are discussed alongside standardized testing approaches.

Wind‐driven seed dispersal differentially promotes seed trapping and retention across alpine plants

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Seed dispersal can mediate species interactions between plants across life stages. Plants can physically stop seed movement (seed trapping) and prevent further dispersal following entrapment (seed retention). We therefore hypothesized seed trapping and retention rates depend on the physical attributes of interacting seeds and plants ...
