Advancing the concept of windows of opportunity to explore the dynamics of the sustainability transition: The development of the EV market in the UK

European Policy Analysis, EarlyView.
Abstract In this study, we seek to understand the interplay between industry and policy, to explain how and why the UK shifted from the promotion of low‐emission road transportation, to policy based on zero tailpipe‐emission electric vehicles (EVs), as part of its evolving net zero ambitions.

The Core Mass Function across Galactic Environments. IV. The Galactic Center

The Astrophysical Journal
The origin of the stellar initial mass function (IMF) and how it may vary with galactic environment is a matter of debate. Certain star formation theories involve a close connection between the IMF and the core mass function (CMF), so it is important to ...

Astrometry of Galactic Star-Forming Region G48.61+0.02 with VERA

, 2011
We performed the astrometry of H2O masers in the Galactic star-forming region G48.61+0.02 with the VLBI Exploration of Radio Astrometry (VERA). We derived a trigonometric parallax of 199+/-7 micro as, which corresponds to a distance of 5.03+/-0.19 kpc ...

Use of virtual reality to engage undergraduate students in environmental field experiences

Future in Educational Research, EarlyView.
Abstract Field‐based experiences enhance cognitive and affective skill sets of undergraduate students. Although field‐based learning is a highly effective pedagogical modality, it is not accessible to all students, necessitating the development and evaluation of alternate modalities that convey equivalent benefits.

The S-Star Cluster at the Center of the Milky Way: On the nature of diffuse NIR emission in the inner tenth of a parsec

, 2012
Sagittarius A*, the super-massive black hole at the center of the Milky Way, is surrounded by a small cluster of high velocity stars, known as the S-stars.

On Sagittarius A* - Theory and Observations

, 2010
Massive and supermassive dust spheres (with a zero internal pressure) collapse to full globes of finite volumes, whose surfaces have the properties of the event horizon around a mass-point. This fact explains the observational data concerning Sagittarius A* (SgrA*). By virtue of Hilbert's repulsive effect, both the event horizon of a mass-point and the

Assessing US and Global Economic Policy Uncertainty Effects on Non‐Performing Loans in MENA's Islamic and Conventional Banks

International Journal of Finance &Economics, EarlyView.
ABSTRACT Banks within the MENA regions serve as pivotal agents in fostering economic growth through extensive lending to businesses, individuals and corporations, thereby amplifying employment within the banking sector. A pressing concern affecting these banks is the proliferation of NPLs, which not only diminishes net earnings but also escalates ...

Climate and political effects on agriculture: Empirical evidence from SSA

International Studies of Economics, EarlyView.
Abstract The most of Sub‐Saharan African (SSA) countries have been affected by climate change and food insecurity problems due to the reduction of production and productivity of cereal crops in the continent. The purpose of this research was to examine the short‐run and long‐run effects of climate change on agricultural productivity in 24 selected SSA ...

Galaxy structure from multiple tracers: I. A census of M87's globular cluster populations

, 2015
We present a new photometric catalogue of the rich globular cluster (GC) system around M87, the brightest cluster galaxy in Virgo. Using archival Next Generation Virgo cluster Survey (NGVS) images in the ugriz bands, observed with CFHT/MegaPrime, we ...
