Thermal-to-nonthermal element abundances in different Galactic environments

, 2021
The non-thermal source abundances of elements play a crucial role in the understanding of cosmic ray phenomena from a few GeV up to several tens of EeV.

Unveiling student sentiment dynamics toward AI‐based education through statistical analysis and Monte Carlo simulation

British Educational Research Journal, EarlyView.
Abstract This study explores the multifaceted dynamics of student sentiment towards artificial intelligence (AI)‐based education by integrating sentiment analysis techniques with statistical methods, including Monte Carlo simulations and decision tree modelling, alongside qualitative grounded theory analysis.

Interstellar Abundances Toward X Per, Revisited

, 2014
The nearby X-ray binary X Per (HD 24534) provides a useful beacon with which to measure elemental abundances in the local ISM. We examine absorption features of 0, Mg, and Si along this line of sight using spectra from the Chandra Observatory's LETG ...

‘When joy comes your way, you have to grab it!’ Troubling how queer joy features in the lives of LGBT+ school‐attending youth in South Africa

British Educational Research Journal, EarlyView.
Abstract Recently, the concept ‘queer joy’ has gained interest in LGBT+ scholarship in the West. I use this scholarship as an entry point to explore how school‐attending LGBT+ youth express joy and how joy serves as a form of resistance against gender and sexuality norms in educational settings.

Spatial Variations of Dust Abundances Across the Large Magellanic Cloud [PDF]

, 2009
Using the data obtained with the Spitzer Space Telescope as part of the Surveying the Agents of a Galaxy's Evolution (SAGE) legacy survey, we have studied the variations of the dust composition and abundance across the Large Magellanic Cloud (LMC).

Beyond standardisation, subjects and syllabi: How primary schools organise for arts richness in an era of curriculum reform

British Educational Research Journal, EarlyView.
Abstract As England embarks on its first comprehensive curriculum review in fifteen years, this paper offers critical insights from schools that sustained arts‐rich provision despite a policy landscape hostile to creative subjects. Drawing on data from the Researching Arts‐rich Primary Schools (RAPS) project—a mixed‐methods study of 76 arts‐rich ...

The ALPINE-CRISTAL-JWST Survey: Chemical Abundance Comparison between the ISM and CGM of Main-sequence Galaxies at z  = 4–6

The Astrophysical Journal
Abstract Gaseous halos around galaxies play an important role in galaxy evolution. The exchange of metals from the interstellar medium (ISM) to the circumgalactic medium (CGM) is caused by the formation, feedback, and/or merging history of galaxies.

Elemental Abundances via X-ray Observations of Galaxy Clusters and the InFOCuS Hard X-ray Telescope [PDF]

, 2004
The first part of this dissertation deals with the oxygen abundance of the Milky Way interstellar medium. Previous measurements had shown that oxygen in the ISM was depleted compared to its abundance in the sun.

Chemical Abundances in a Turbulent Medium–H₂, OH⁺, H₂O⁺, ArH⁺

, 2019
Supersonic turbulence results in strong density fluctuations in the interstellar medium (ISM), which have a profound effect on the chemical structure. Particularly useful probes of the diffuse ISM are the ArH+, OH+, H2O+ molecular ions, which are highly ...

Lessons from primary school students' perceptions of the factors that influence school connectedness

British Educational Research Journal, EarlyView.
Abstract School connectedness is critical to improving students' health, development and wellbeing. Research into primary school students' perceptions of the factors that influence their sense of connectedness is essential for identifying practices that promote success.
