T. rex cognition was T. rex‐like—A critical outlook on diverging views of the neurocognitive evolution in dinosaurs

The Anatomical Record, EarlyView.
Abstract A recent debate has emerged between Caspar et al. (2024) and Herculano‐Houzel (2023) on inferring extinct dinosaur cognition by estimating brain neuron counts. While thought‐provoking, the discussion largely overlooks the function of cognition, as well as partly neglects the difficulties involved in estimating neuron numbers, which according ...

Community intermediary strategies and tactics to close digital divides and enhance equitable technology use in everyday life

Journal of the Association for Information Science and Technology, EarlyView.
Abstract Online technologies are required for accessing essential services, such as healthcare, transportation, and education. Challenges to online technology access can prevent resource‐constrained communities from connecting to these services. Human intermediaries who act in the middle space between technology and the person using the technology may ...

Parenting Stress and Stressful Life Events Among Caregivers of Toddler Siblings of Autistic and Non‐Autistic Children

Autism Research, EarlyView.
ABSTRACT This study measured experiences of parenting stress and stressful life events in caregivers of families with a toddler who has either an autistic or non‐autistic older sibling(s). Caregivers of toddlers (12–18 months old) with older autistic siblings (Sibs‐autism; n = 58) and toddlers with older non‐autistic siblings (Sibs‐NA; n = 46 ...

Dynamic Capacity and Surface Fatigue Life for Spur and Helical Gears [PDF]

A mathematical model for surface fatigue life of gear, pinion, or entire meshing gear train is given. The theory is based on a previous statistical approach for rolling-element bearings. Equations are presented which give the dynamic capacity of the gear

A pipeline crisis or a sustainability crisis? Local and national succession planning for headteachers in England

British Educational Research Journal, EarlyView.
Abstract Recruiting and retaining school leaders is a challenge in many systems worldwide. Previous research has identified three distinct ways in which succession planning can be conceptualised and approached: a ‘pipeline’ approach seeks to match supply and demand for the posts that need filling; a ‘pool’ strategy involves proactively identifying and ...

The impact of trauma‐informed teacher education

British Educational Research Journal, EarlyView.
Abstract In this study, two cohorts of university students in an employment‐based teacher education course undertook trauma‐informed education training embedded within their coursework to enhance their preparedness to work with diverse learners and their self‐efficacy for trauma‐informed teaching. With increased calls for teacher preparation programmes

Counting cases, conserving species: addressing highly pathogenic avian influenza in wildlife

Biological Reviews, EarlyView.
ABSTRACT Highly pathogenic avian influenza (HPAI) has become a critical threat to wildlife, shifting from a seasonal epizootic to a persistent, year‐round panzootic with global consequences. Here, we summarise the origin, evolutionary mechanisms, and expanding host range of the current H5N1 virus (clade 2.3.4.4b) and assess its impact on wildlife. Over
