Critical pedagogy in hard financial times
No full textPeter Mayo takes issue with education financing not from an economic or technical
viewpoint, but from a philosophical and systemic one, drawing on critical pedagogy.
There is no sense, this article argues, to talk of higher education or its funding without
reference to the capitalist system which the mainstream education discourse reaffirms. The author concludes with an alternative vision of lifelong learning as a social act for the creation and enhancing of democratic spaces, reflected in the ongoing global “Occupy” protests for social equality.peer-reviewe

Object drop in L3 acquisition
No full textThe topic of cross-linguistic differences regarding the overt or null expression of arguments has been considered both in first (L1) and second language (L2) acquisition. There is abundant literature on both subject and object drop with different language pairings but the issue has not been considered in third language (L3) acquisition. The main goal of this article is to analyse the L3 interlanguage of Basque-Spanish bilinguals regarding the acceptability and interpretation of null objects. The three languages involved in the study display different semantic requirements for the target structure, with Basque allowing for a null object option across-the-board, Spanish only under certain semantic conditions, and English disallowing it in the standard variety. Two trilingual, one bilingual and a control group (n = 119) rated experimental items embedded in context, presented in a written and aural format on a computer screen. Findings point to the successful acquisition of the target structure, as well as a clear influence of Spanish in the three experimental groups

A biomechanical study of top screw pullout in anterior scoliosis correction constructs
No full textTop screw pullout is a significant problem in anterior scoliosis correction, with rates of 5-15% reported in the literature. The Mater Misericordiae Hospital in Brisbane currently has a series of 125 patients with scoliosis treated by thoracoscopic anterior fusion, instrumentation and correction between April 2000 and August 2007. In this series 11 top screws are known to have pulled out (a rate of 8.8%), with six occurring in the first week, and all within 6 weeks, suggesting that the problem is one of excessive static force rather than fatigue.\ud
\ud
This thesis describes a biomechanical investigation into the mechanics of vertebral body screw pullout in anterior scoliosis surgical constructs. Previous biomechanical studies of vertebral body screws have evaluated their resistance to either straight pullout or cephalo-caudad compression forces, however the aim of this study was to assess screw resistance to more realistic loading conditions, namely pullout of initially angled screws, and pullout where the motion path is an arc rather than a straight axial pullout, as would be expected in a single rod anterior construct.\ud
\ud
The first series of experiments involved straight and angled pullout tests using synthetic bone. In the angled tests, both locked and free-to-pivot configurations were tested. The second series of experiments tested the effect of cephalo-caudad pre-compression (the actual deformity correction step performed during surgery) on subsequent axial pullout strength. A third series of experiments performed arc pullouts using synthetic bone, and the final series of experiments tested the pullout resistance of a newly proposed screw position configuration against the standard screw positioning using ovine lumbar vertebrae. \ud
\ud
Synthetic bone testing revealed that for initially angled pullout, resistance is greatest as the screw angle approaches 0 (ie a direct axial pullout). Cephalo-caudad pre-compression reduced subsequent pullout strength for cases where a staple was not used under the screw head, but if a staple was used the pre-compression did not decrease pullout force significantly. Arc pullout resistance was greatest when the screw was angled at 10 cephalad, and the mean pullout strength for the proposed screw configuration using ovine lumbar vertebrae (1864N) was almost double that of the standard screw positioning (993N). \ud
\ud
The clinical implication of this study is that top screw pullout resistance can be maximised by placing the top screw as close as possible to the top endplate and the bottom screw as close as possible to the bottom endplate, although this will have detrimental effects on the pullout of the second screw should the top screw pull out. Screw angulation is a less important factor but any angulation should be in a cephalad direction and around 10º in magnitude. The experimental results also suggest that the use of a staple may play a role in preventing cephalo-caudad pre-compression forces from reducing screw resistance to subsequent pullout forces
Exoplanet atmospheres at high resolution through a modest-size telescope. Fe II in MASCARA-2b and KELT-9b with FIES on the Nordic Optical Telescope
No full textGround-based, high-resolution spectrographs are providing us with an
unprecedented view of the dynamics and chemistry of the atmospheres of planets
outside the Solar System. While there is a large number of stable and precise
high-resolution spectrographs on modest-size telescopes, it is the
spectrographs at observatories with apertures larger than 3.5 metres that
dominate the atmospheric follow-up of exoplanets. In this work, we explore the
potential of characterising exoplanetary atmospheres with FIES, a
high-resolution spectrograph at the 2.56 metre Nordic Optical Telescope. We
observed two transits of MASCARA-2 b (also known as KELT-20 b) and one transit
of KELT-9 b to search for atomic iron, a species that has been recently
discovered in both neutral and ionised forms in the atmospheres of these
ultra-hot Jupiters using large telescopes. Using a cross-correlation method, we
detect a signal of Fe II at the and level in the
transits of MASCARA-2 b. We also detect Fe II in the transit of KELT-9 b at the
level. Although we do not find any significant Doppler shift in the
signal of MASCARA-2 b, we do measure a moderate blueshift (3-6 km/s) of the
feature in KELT-9 b, which might be a manifestation of high-velocity winds
transporting Fe II from the planetary dayside to the nightside. Our work
demonstrates the feasibility of investigating exoplanet atmospheres with FIES,
potentially unlocking a wealth of additional atmosphere detections with this
and other high-resolution spectrographs mounted on similar-size telescopes.Comment: 9 pages, 6 figures, accepted to A&
The CHAIN-REDS Semantic Search Engine
No full texte-Infrastructures, and in particular Data Repositories and Open Access Data Infrastructures, are essential platforms for e-Science and e-Research and are being built since several years both in Europe and the rest of the world to support diverse multi/inter-disciplinary Virtual Research Communities. So far, however, it is difficult for scientists to correlate papers to datasets used to produce them and to discover data and documents in an easy way. In this paper, the CHAINREDS project’s Knowledge Base and its Semantic Search Engine are presented, which attempt to address those drawbacks and contribute to the reproducibility of science
