Crowding is the inability to recognize an object in clutter, classically considered a fundamental low-level bottleneck to object recognition. Recently, however, it has been suggested that crowding, like predictive phenomena such as serial dependence, may result from optimizing strategies that exploit redundancies in natural scenes. This notion leads to several testable predictions, such as crowding being greater for nonsalient targets and, counterintuitively, that flanker interference should be associated with higher precision in judgements, leading to a lower overall error rate.

Adaptation is a ubiquitous property of perceptual systems, increasing sensitivity to change and allowing them to operate over a large dynamic range. The number sense, like most other perceptual systems, is adaptable. Yousif et al.

The COVID-19 pandemic continues to cause nurses stress and trauma, with alcohol potentially being used to manage this stress. Prior studies of nurses' alcohol consumption during the COVID-19 pandemic have shown increases in alcohol consumption to manage stress associated with the pandemic. The aim of this paper is to explore perceptions of alcohol consumption and stress among nurses, particularly since the declared end of the COVID-19 pandemic.

Aim: To determine the acceptability of targeted apps and provide recommendations for the implementation of and app addressing high risk alcohol use to nurses.

Design: A qualitative descriptive study design, using the Behavioural Change Wheel implementation framework.

Methods: Semi-structured interviews with 42 Australian nurses were subject to structural coding using the Capability, Opportunity, and Motivation (COM-B) model linked to the Behaviour Change Wheel.

Article Synopsis
  • The study focuses on creating a reliable model for bone failure under repetitive loading, addressing limitations of previous uniaxial models that overestimate bone durability during physical activity.
  • Using cadaveric tibiae from donors aged 21 to 85, the research tested four engineering failure criteria (Von Mises, Tsai-Wu, Findley critical plane, and maximum shear strain) to better predict fatigue fractures.
  • Results showed that older individuals experience significantly lower fatigue life, with the model accurately predicting fracture occurrences after 5,000 to 200,000 cycles of activity, highlighting age-related risks in bone health.
