Psychometric Properties of the French Version of the Provider Co-Management Index-RN
Background Strengthening primary care through team-based models is a global priority as strong primary care systems are consistently associated with improved outcomes. The Provider Co-Management Index for Registered Nurses (PCMI-RN) is a validated instrument measuring co-manageme...

Sensory receptor expansion and neural accommodation in butterfly color vision
The evolution of complex brains required the incorporation of newly evolved neurons into existing circuits, yet the genetic and developmental mechanisms enabling their integration remain poorly understood. Butterflies expanded their color vision by adding a second R7 photorecepto...

Do Children Who Develop Faster Go on to Age Faster in Midlife?
We quantified the association between rate of child development and pace of midlife aging in the Dunedin Study and the Add Health Study. Physical development was quantified in Dunedin participants ( N = 1,037; age 45) using a composite comprised of (1) birth weight for gestationa...

Parental Stigma and “Good Parenting” in Child and Adolescent Mental Health
OBJECTIVE: Parents of children with mental health problems often experience judgment about their parenting. Such stigma is associated with lower parental well-being and greater child symptom severity. Theory-driven descriptions of and interventions for parental stigma are limited...

Exclusion of Participants for Substance Use in Clinical Trials
Patterns of inclusion and exclusion of individuals who use illicit substances from clinical trials have not been well-studied. Given the widespread and increasing prevalence of drug use in the United States, this has significant implications for the generalizability of scientific...

For ethylene carbonate on the (100) surface of lithium, we calculate the adsorption energy in two binding motifs and the barrier height for a ring-opening decomposition reaction. We validate a scheme for producing results in the thermodynamic limit by correcting results obtained...

Universal compactified Jacobians: cohomological invariance and boundary combinatorics
Abstract Pagani and Tommasi have introduced a class of smoothable fine compactified Jacobians $$\overline{\mathcal {J}}_{g,n}^{\,d}(\sigma )\rightarrow \overline{\mathcal {M}}_{g,n}$$ J ¯ g , n d ( σ ) → M ¯ g , n over the moduli space of stable curves, depending nontrivially on...

Abstract Background Medical students are exposed to academic and lifestyle factors that may adversely affect cardiovascular and psycho-emotional health. Although these outcomes have been widely studied, most evidence is cross-sectional, and longitudinal evidence from Latin Americ...

Evaluation of a Commercial Pediatric Sepsis Early Detection Alert in the Emergency Department
Importance Screening tools have been implemented with the goal of improving early detection of pediatric sepsis, with limited evidence of effectiveness. The Epic Systems Pediatric Sepsis Early Detection Model (PESM) and its associated clinical alert have been widely implemented i...

Navigating equity tensions and enacting agency in Chinese TESOL practicums
This qualitative study examined how 38 preservice TESOL teachers placed in Chinese middle schools identified, navigated, and challenged perceived pedagogical inequities during a brief practicum. Using a critical sociocultural framework, reflective papers ( N = 38) and focus group...

Abstract Recent works suggest there are periods when the Sun encountered massive interstellar cold clouds which compressed the heliosphere to within Earth's orbit, exposing Earth to interstellar galactic cosmic rays and energetic particles of heliospheric origin. We model 10 Be p...

Scalable, Simple, and Versatile Encapsulation of 2D Materials and Devices
Abstract Air-sensitive 2D materials present fundamental challenges for device integration. Encapsulation is required to preserve intrinsic properties, yet conventional strategies require complicated fabrication workflows and fail with thicker flakes. We demonstrate that electron-...

Revising the Spin and Kick Connection in Isolated Binary Black Holes
Abstract The origin of black hole (BH) spins remains one of the least understood aspects of BHs. Despite many uncertainties, it is commonly assumed that if BHs originated from isolated massive star binaries, their spins should be aligned with the orbital angular momentum of the b...
