In-between spaces of policy and practice: Voices from Prince Edward Island early childhood educators
No full textOver the course of the past decades, the discourse, pedagogy, scope, and delivery of early learning and child care (ELCC) has undergone myriad significant changes internationally, nationally, and at local levels. Prince Edward Island (PEI), the smallest Canadian Province, has not been exempt from these transformations. By situating early childhood educators (ECEs) at the centre of ecological multilevel environments (Bronfenbrenner, 2005), this qualitative study explored how a system-wide change implemented through the Prince Edward Island Preschool Excellence Initiative (PEIPEI) has impacted and is being impacted by ECEs over time. Purposive sampling was used to invite seven early childhood educators working on provincially regulated early years centres (EYCs) to participate in individual interviews. Findings indicated that ECEs have been striving to navigate and merge the space in-between policy and practices and that after ten years, they remain in this liminal space where they continue to navigate unravelling transitions as they search for their professional identity
Numerical Method for Bertrand Mean Field Games Using Multigrid
No full textAbstract We study dynamic Bertrand mean field games (MFG) with exhaustible capacities in which companies compete with each other using the price as the strategic variable and the interaction among the competition is through the average price. We consider both continuum mean field games and finite player games. Dynamic continuum mean field games can be modeled as a system of partial differential equations (PDEs) which consists of a backward Hamilton-Jacobi-Bellman (HJB) equation for the value function and a forward Kolmogorov equation for the density function. This system is coupled through the proportion of remaining companies and the average equilibrium price. Finite N-player games can be approximated using the framework of continuum mean field games. Due to the substantial computational cost of solving the HJB equation, we present an efficient multigrid method with Full Approximation Scheme (FAS) to solve this equation. An iterative algorithm is applied to solve the whole MFG problem. Numerical results illustrate the effects of the competition on the proportion of active companies and the average equilibrium price. ii
Author Correction: Plastic waste discharge to the global ocean constrained by seawater observations
No full textCorrection to: Nature Communications, published online 13 March 2023 The original version of this Article contained an error in Fig. 2, in which c was incorrectly described as “middle scenario” where it should have been described as “low scenario”. The correct version of Fig. 2 is: (Figure presented.) which replaces the previous incorrect version: (Figure presented.) This has been corrected in both the PDF and HTML versions of the Article.Coastal Engineerin
Control of the yield of surviving Rydberg atoms in strong-field ionization with two-color laser fields
No full textWe theoretically investigate the controllable yield of neutral excited atoms surviving in the tunneling ionization process using two-color fields with parallel and orthogonal polarizations. Using the classical-trajectory Monte Carlo model, we show that the yield of the surviving Rydberg atoms after tunneling ionization can be modulated by varying the relative phase of the two frequency components. Tracing back to the initial tunneling coordinates at the tunnel exit of the electrons that contribute to the surviving atoms, we find the distribution of these coordinates shifts with the relative phase and the polarization configuration of the two-color fields. The orthogonally polarized two-color field counterintuitively tends to recapture more electrons than the two-color field with parallel polarizations.National Program on the Key Basic Research [2013CB922403]; National Science Foundation of China [11134002]SCI(E)ARTICLE125
Plastic waste discharge to the global ocean constrained by seawater observations
No full textMarine plastic pollution poses a potential threat to the ecosystem, but the sources and their magnitudes remain largely unclear. Existing bottom-up emission inventories vary among studies for two to three orders of magnitudes (OMs). Here, we adopt a top-down approach that uses observed dataset of sea surface plastic concentrations and an ensemble of ocean transport models to reduce the uncertainty of global plastic discharge. The optimal estimation of plastic emissions in this study varies about 1.5 OMs: 0.70 (0.13–3.8 as a 95% confidence interval) million metric tons yr−1 at the present day. We find that the variability of surface plastic abundance caused by different emission inventories is higher than that caused by model parameters. We suggest that more accurate emission inventories, more data for the abundance in the seawater and other compartments, and more accurate model parameters are required to further reduce the uncertainty of our estimate.Coastal Engineerin
