Failure in Motion: A Framework for Capability Erosion and Institutional Dysfunction

Strategic Change, EarlyView.
ABSTRACT Drawing on the literature on capability erosion and institutional dysfunction (ID), this study develops a conceptual framework that sheds new light on how the interaction between capability erosion and ID creates conditions for business failure across borders. By articulating two dimensions of heterogeneous capability and resource erosion (i.e.

Commonality Considerations in the Design of Flight Deck of Civil Aircraft

Journal of Physics: Conference Series, 2020
Commonality in the flight deck can reduce development costs, shorten the time of operational courses e.g. transition time of pilots and expand the market, thus is becoming one of the most important features of modern civil aircraft design.

DNA barcoding for identification of species involved in wildlife strikes at Brazilian airports

The Journal of Wildlife Management, EarlyView.
A collaborative network of 42 Brazilian airports applied DNA barcoding to identify 80 species involved in wildlife strikes. Among them, 32 species (17 birds and 15 bats) were not currently available in Brazil's wildlife strike reporting database, underscoring the value of molecular tools for strengthening wildlife strike monitoring.

Evaluating Erosional Stability of Reconstructed Mine Landscapes Using Landform Evolution Models: Parameterisation and Decadal‐Scale Erosion Assessment

Land Degradation &Development, EarlyView.
ABSTRACT Ensuring the long‐term erosional stability of post‐mining landforms remains a major challenge in open‐pit mining. Reconstructed landscapes must support the agreed post‐mining land use, such as cattle grazing in the Hunter region of southeastern Australia, requiring stable pasture and minimal soil loss.

Thermal runaway safety analysis of eVTOL based on evidence theory and interval analysis

Xibei Gongye Daxue Xuebao
In order to ensure the safety of eVTOL, safety analysis of thermal runaway problem of lithium battery is needed. Due to insufficient failure data, a safety assessment method based on evidence theory and interval analysis is proposed.
