A benefit‐cost analysis of child care subsidy expansions: The New York State case

Contemporary Economic Policy, EarlyView.
Abstract Proposals to expand child care assistance have proliferated at the national and state levels. This paper uses a novel approach to estimate the benefits and costs of providing child care subsidies to families up to three times the federal poverty line while supplementing child care worker compensation — a recently‐enacted reform in New York ...

Density resummation of perturbation series in a pion gas to leading order in chiral perturbation theory

, 2006
The mean field (MF) approximation for the pion matter, being equivalent to the leading ChPT order, involves no dynamical loops and, if self-consistent, produces finite renormalizations only.

The S-Wave Pion-Nucleon Scattering Lengths from Pionic Atoms using Effective Field Theory [PDF]

, 2002
The pion-deuteron scattering length is computed to next-to-next-to-leading order in baryon chiral perturbation theory. A modified power-counting is then formulated which properly accounts for infrared enhancements engendered by the large size of the ...

Barriers and Facilitators in Implementing Clinical Practice Guidelines Among Nurses in Emergency Departments and Critical Care Units: A Systematic Review

Journal of Clinical Nursing, EarlyView.
ABSTRACT Aim This systematic review explored the barriers and facilitators to the implementation of clinical practice guidelines (CPGs) among nurses in emergency departments (EDs) and critical care units (CCUs). Design Systematic review. Method A systematic review was performed using both qualitative and quantitative studies from five databases (CINAHL,

Pion nucleus Drell–Yan process and parton transverse momentum in the pion

European Physical Journal C: Particles and Fields, 2018
We present a thorough analysis of unpolarized Drell–Yan (DY) pair production in pion–nucleus scattering. On the nucleus side, we use nuclear parton distributions along with parametrisations of the nucleon partonic transverse distribution available in the

Narcissism Is Associated With Blunted Error‐Related Brain Activity

Journal of Personality, EarlyView.
ABSTRACT Objective Narcissism is associated with self‐enhancement and social antagonism, yet its neural underpinnings, particularly in error processing, remain underexplored. Competing theoretical models, such as the mask model and the metacognitive model, offer conflicting hypotheses regarding how narcissism influences early neural responses to errors.

The width of the Δ-resonance at two loop order in baryon chiral perturbation theory

Physics Letters B, 2016
We calculate the width of the delta resonance at leading two-loop order in baryon chiral perturbation theory. This gives a correlation between the leading pion–nucleon–delta and pion–delta couplings, which is relevant for the analysis of pion–nucleon ...
