In 2004, a new form of inspection was introduced to post-primary schools in the Republic of Ireland. It represented a complete change from the previous light touch pattern and reflected the New ...Public Management approach to policymaking and implementation then becoming fashionable in the jurisdiction. Around the same time, a new policy for tackling educational disadvantage was adopted. Recent case-study research into the effectiveness of this policy elicited views from six school communities on a wide range of issues. One was the experiences of teachers and school leaders in dealing with the impact of the new inspection regime over the last fifteen years. The picture that emerged is a cause of serious concern.
Abstract
We present the on-orbit performance of the Colorado Ultraviolet Transit Experiment (CUTE). CUTE is a 6U CubeSat that launched on 2021 September 27 and is obtaining near-ultraviolet (NUV; ...2480 Å-3306 Å) transit spectroscopy of short-period exoplanets. The instrument comprises a 20 cm × 8 cm rectangular Cassegrain telescope, an NUV spectrograph with a holographically ruled aberration-correcting diffraction grating, and an NUV-optimized CCD detector. The telescope feeds the spectrograph through an 18′ × 60″ slit. The detector is a passively cooled, back-illuminated NUV-enhanced CCD. The spacecraft bus is a Blue Canyon Technologies XB1, which has demonstrated ≤ 6″ jitter in 56% of CUTE science exposures. Following spacecraft commissioning, an on-orbit calibration program was executed to characterize the CUTE instrument’s on-orbit performance. The results of this calibration indicate that the effective area of CUTE is ≈19.0–27.5 cm

and that the average intrinsic resolution element is 2.9 Å across the bandpass. This paper describes the measurement of the science instrument performance parameters as well as the thermal and pointing characteristics of the observatory.
Abstract
Ultraviolet observations of ultrahot Jupiters, exoplanets with temperatures over 2000 K, provide us with an opportunity to investigate if and how atmospheric escape shapes their upper ...atmosphere. Near-ultraviolet transit spectroscopy offers a unique tool to study this process owing to the presence of strong metal lines and a bright photospheric continuum as the light source against which the absorbing gas is observed. WASP-189b is one of the hottest planets discovered to date, with a dayside temperature of about 3400 K orbiting a bright A-type star. We present the first near-ultraviolet observations of WASP-189b, acquired with the Colorado Ultraviolet Transit Experiment (CUTE). CUTE is a 6U NASA-funded ultraviolet spectroscopy mission, dedicated to monitoring short-period transiting planets. WASP-189b was one of the CUTE early science targets and was observed during three consecutive transits in 2022 March. We present an analysis of the CUTE observations and results demonstrating near-ultraviolet (2500–3300 Å) broadband transit depth (

Abstract
Atmospheric escape is a fundamental process that affects the structure, composition, and evolution of many planets. The signatures of escape are detectable on close-in, gaseous exoplanets ...orbiting bright stars, owing to the high levels of extreme-ultraviolet irradiation from their parent stars. The Colorado Ultraviolet Transit Experiment (CUTE) is a CubeSat mission designed to take advantage of the near-ultraviolet stellar brightness distribution to conduct a survey of the extended atmospheres of nearby close-in planets. The CUTE payload is a magnifying near-ultraviolet (2479–3306 Å) spectrograph fed by a rectangular Cassegrain telescope (206 mm × 84 mm); the spectrogram is recorded on a back-illuminated, UV-enhanced CCD. The science payload is integrated into a 6U Blue Canyon Technology XB1 bus. CUTE was launched into a polar, low-Earth orbit on 2021 September 27 and has been conducting this transit spectroscopy survey following an on-orbit commissioning period. This paper presents the mission motivation, development path, and demonstrates the potential for small satellites to conduct this type of science by presenting initial on-orbit science observations. The primary science mission is being conducted in 2022–2023, with a publicly available data archive coming online in 2023.
Existing research in the area of educational disadvantage in the Irish context is located either within the historiography of policy in the area or in contemporary macro analysis of dominant trends. ...The existing canon of research tells us that prolonged periods of unemployment and poorer health outcomes are features of early school leavers, that the educational experience of young people are reflected in their future life trajectories, and that inter-generational transmission is common. While broader macro analysis is fundamental in informing policy, context-specific research is also critical in shaping the policy trajectory and policy implementation. This article provides for the first time in Irish post-primary education an in-depth examination of the experience of existing policy in six case study schools, as articulated through the voices of school leaders, teachers, parents and pupils. The focus here is on the adequacy or otherwise of the resources provided under the DEIS (Delivering Equality of Opportunity in Schools) programme in light of the particular challenges those school communities face. Clear evidence emerges that not only are the resources inadequate but that mechanisms are in place in the state's funding of post-primary schools to ensure the perpetuation of educational disadvantage.
According to the Edelman Trust Barometer 2020, which tracks consumer sentiment across a range of sectors, Americans distrust--or are at least ambivalent about--the development of advanced ...technologies such as artificial intelligence (AI) by companies that may not be positively and responsibly shaping our future. However, according to a 2019 survey from the University of Oxford's Future of Humanity Institute, half of Americans surveyed said they trusted higher education (and the military) above all (more than government agencies, non-profit research collaboratives, and big technology companies) to build, manage, and govern artificial intelligence. We should lean into this finding. It not only signifies at least a pocket of trust remaining in higher education institutions but also offers an opportunity for college/university researchers, faculty, staff, and administrators to regain lost ground and exemplify AI leadership at a time when our institutions--and our world--need us most.
