Mixed‐Mode Stress Intensity Factor Evaluation via Thermoelastic Stress Analysis Including Non‐Adiabatic Correction

open access: yesFatigue &Fracture of Engineering Materials &Structures, EarlyView.
ABSTRACT Characterization of the crack tip, such as the stress intensity factor (SIF), is a vital step for the assessment of fatigue crack growth and prediction of potential failure in engineering structures. This study investigates the use of thermoelastic stress analysis (TSA) for SIF evaluation, including a methodology for non‐adiabatic stress field

The Inclusionary Effects of Performing Work: A Practice‐Theoretical Study of Airport Security Work

open access: yesJournal of Management Studies, EarlyView.
Abstract In contrast to inclusion research that often treats work as a neutral, passive background, this study theorizes the active role of work in producing an inclusive organization. We adopt a practice‐theoretical approach that examines the accomplishment of work activities through their discourses, embodiment, and material arrangements, critically ...

Is sleep affected after microgravity and hypergravity exposure? A pilot study

open access: yesJournal of Sleep Research, Volume 34, Issue 2, April 2025.
Summary Sleep is known to be affected in space travel and in residents of the international space station. But little is known about the direct effects of gravity changes on sleep, if other factors, such as sleep conditions, are kept constant. Here, as a first exploration, we investigated sleep before and after exposure to short bouts of microgravity ...

The Mathematical History Behind the Granger–Johansen Representation Theorem

open access: yesOxford Bulletin of Economics and Statistics, EarlyView.
ABSTRACT When can a vector time series that is integrated once (i.e., becomes stationary after taking first differences) be described in error correction form? The answer to this is provided by the Granger–Johansen representation theorem. From a mathematical point of view, the theorem can be viewed as essentially a statement concerning the geometry of ...

Community acceptance of helicopter noise: Criteria and application [PDF]

open access: yes
A study was conducted to define those criteria necessary for civil helicopter operations to be acoustically acceptable to the communities from which they operate and over which they fly.
