School readiness and the good level of development: Policy constructions in English early childhood education

open access: yesBritish Educational Research Journal, EarlyView.
Abstract This paper critically analysed how school readiness has been historically and discursively constructed in Early Childhood Education (ECE) policy in England over the past four decades. Using Bacchi's ‘What's the Problem Represented to be?’ framework and Foucauldian concepts of governmentality, the paper explored how school readiness has shifted

NeBULA: a web-based novel drug design platform for up-to-date bioisosteric replacement

open access: yesMedicine in Drug Discovery
Bioisosteric replacement is an important method for rational drug design. It enables the modification of key pharmacophores or functional groups to achieve desired molecular properties.

Observations of the Crab Nebula and Pulsar with the Large-sized Telescope Prototype of the Cherenkov Telescope Array

open access: yesThe Astrophysical Journal, 2023
The Cherenkov Telescope Array (CTA) is a next-generation ground-based observatory for gamma-ray astronomy at very high energies. The Large-Sized Telescope prototype (LST-1) is located at the CTA-North site, on the Canary Island of La Palma.

Cloud fragmentation and proplyd-like features in HII regions imaged by HST [PDF]

open access: yes, 2006
We have analyzed HST ACS and WFPC2 new and archival images of eight HII regions to look for new proto-planetary disks (proplyds) similar to those found in the Orion Nebula.

The Role of Sustainable Social Media Marketing Activities in Raising Bottom‐of‐the‐Pyramid Customers' Engagement, Satisfaction, and Subjective Well‐Being

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT Though prior studies have explored the effects of firms' social media marketing activities on customer engagement, the dynamics characterizing this association in bottom‐of‐the‐pyramid (BoP) markets remain tenuous, exposing a critical gap. Addressing this gap, we develop and test a model assessing (a) the effects of firms' sustainable social ...

ABOUT TEMPERATURE FIELDS AND CONDITIONS OF GASEOUS CONDENSATION OF NEBULAES IN THE PLANETARY VORTEX

open access: yesVìsnik Dnìpropetrovsʹkogo Unìversitetu: Serìâ Modelûvannâ, 2014
New exact solution of the spherically-axissymmetric Eiler's equations, called as plan­etary vortex, is applied to the problem of formation in planetary nebula germs of planets due to the condensation of gases in the areas of vortex instability which ...

The ionization structure of multiple shell planetary nebulae: I. NGC 2438

open access: yes, 2014
In recent times an increasing number of extended haloes and multiple shells around planetary nebulae have been discovered. These faint extensions to the main nebula trace the mass-loss history of the star, modified by the subsequent evolution of the ...

Degree theory for 4‐dimensional asymptotically conical gradient expanding solitons

open access: yesCommunications on Pure and Applied Mathematics, EarlyView.
Abstract We develop a new degree theory for 4‐dimensional, asymptotically conical gradient expanding solitons. Our theory implies the existence of gradient expanding solitons that are asymptotic to any given cone over S3$S^3$ with non‐negative scalar curvature. We also obtain a similar existence result for cones whose link is diffeomorphic to S3/Γ$S^3/\

LAMOST Medium-resolution Spectroscopic Survey of the Rosette Nebula

open access: yesThe Astronomical Journal
We report multifiber, medium-resolution spectroscopy of the Rosette Nebula with full spatial coverages, and present a table of the nebular parameters based on the spatially resolved measurements of emission lines.
