Performance, academic context and self-reported health in psychology students before and after of the EHEA
[EN] The European Higher Education Area (EHEA) has involved a number of structural and methodological changes whose results on academic performance and student health have not been sufficiently studied. The purpose of this paper is to evaluate the performance, perceived context and self-reported health of a sample of undergraduate and graduate Psychology students to see how these variables relate to and influence their academic achievement and welfare. Methodology. The sample consisted of 811 students (487 pre-Bologna system and 324 bacherlor Ìs degree). For the evaluation of the indicated variables, the following instruments were used: the Academic Context questionnaire, to evaluate the educational environment; the GHQ-28 questionnaire to evaluate the self-reported health; and the CHAS (Cuestionario de HĂĄbitos de Sueño, in Spanish, Sleeping Habits Questionnaire), in addition, the academic performance was collected. Results. EHEA students perform better than students pre-Bologna, although the difference is not very high. They are also more dissatisfied with the results obtained, they have worse psychological health, worse quality of sleep, greater anxiety and insomnia, greater social dysfunction, in addition, they need more medical leave due to stress and anxiety. Conclusions. Adaptation to the EHEA does not seem to achieve its objectives of improving the quality of education and having a negative impact on the health and physical and psychological well-being of students.[ES] El Espacio Europeo de EducaciĂłn Superior (EEES) ha implicado una serie de modificaciones a nivel estructural y metodolĂłgico cuyos resultados sobre el rendimiento acadĂ©mico y la salud de los estudiantes no se han estudiado suficientemente. El objetivo de este trabajo es evaluar el rendimiento, el contexto percibido y la salud auto informada de una muestra de estudiantes de PsicologĂa de licenciatura y grado, para ver cĂłmo se relacionan estas variables e influyen en sus resultados acadĂ©micos y bienestar. MetodologĂa. La muestra estuvo compuesta por 811 estudiantes (487 de licenciatura y 324 de grado).

Resultados. Los estudiantes del EEES obtienen un mejor rendimiento que los de licenciatura, aunque la diferencia no es muy elevada. AsĂ mismo muestran estar mĂĄs insatisfechos con los resultados obtenidos, tienen peor salud psicolĂłgica, peor calidad de sueño, mayor ansiedad e insomnio, mayor disfunciĂłn social y mĂĄs bajas mĂ©dicas por estrĂ©s y ansiedad. Conclusiones. La adaptaciĂłn al EEES parece que no cumple con sus objetivos de mejora de la calidad de la enseñanza ademĂĄs de tener un impacto negativo en la salud y bienestar fĂsico y psicolĂłgico de los estudiantes.LĂłpez-NĂșñez, M.; Rubio-Valdehita, S.; DĂaz Ramiro, E.

Effects of math anxiety on student success in higher education
This study examines whether math anxiety and negative attitudes toward mathematics have an effect on university students" academic achievement in a methodological course forming part of their degree. A total of 193 students were presented with a math anxiety test and some questions about their enjoyment, self-confidence and motivation regarding mathematics, and their responses were assessed in relation to the grades they had obtained during continuous assessment on a course entitled"Research Design". Results showed that low performance on the course was related to math anxiety and negative attitudes toward mathematics. We suggest that these factors may affect students" performance and should therefore be taken into account in attempts to improve students" learning processes in methodological courses of this kind
Evidence for a mixed mass composition at the `ankle' in the cosmic-ray spectrum
We report a first measurement for ultra-high energy cosmic rays of the
correlation between the depth of shower maximum and the signal in the water
Cherenkov stations of air-showers registered simultaneously by the fluorescence
and the surface detectors of the Pierre Auger Observatory. Such a correlation
measurement is a unique feature of a hybrid air-shower observatory with
sensitivity to both the electromagnetic and muonic components. It allows an
accurate determination of the spread of primary masses in the cosmic-ray flux.
Up till now, constraints on the spread of primary masses have been dominated by
systematic uncertainties. The present correlation measurement is not affected
by systematics in the measurement of the depth of shower maximum or the signal
in the water Cherenkov stations. The analysis relies on general characteristics
of air showers and is thus robust also with respect to uncertainties in
hadronic event generators. The observed correlation in the energy range around
the `ankle' at differs significantly from
expectations for pure primary cosmic-ray compositions. A light composition made
up of proton and helium only is equally inconsistent with observations. The
data are explained well by a mixed composition including nuclei with mass . Scenarios such as the proton dip model, with almost pure compositions, are
thus disfavoured as the sole explanation of the ultrahigh-energy cosmic-ray
flux at Earth.Comment: Published version. Added journal reference and DOI. Added Report

Diatreta Cups, Light in Roman Dining Spaces
Cage cups or Diatreta are ancient Roman glass vessels produced by creating a thick blown blank of glass that, once cooled down, is taken to a glass cutter or diatretarii. The latter would cut and carve away most of the glass leaving a transparent vessel inside and an open-work decoration separated through thin posts of glass. The work is very delicate and exclusive, produced within limited space in time with no record of similar vessels until the late 1800 (Donald B. Harden & Toynbee 1959, p.181). Many of these glass objects have good-will inscriptions or decorations that express the importance of drinking. As for their provenance, most âwhen found in context- have been found in pagan burials. Nevertheless some fragments have been found in Christian environments or with Christian motifs like the SzekszĂĄrd cup. The location of these finds is mostly in the Rhine area ânorthern Empire, when Milan was one of its capitals (Aquaro 2004)- but the actual extent of finds expand throughout the 4th century extent of the Roman Empire. Considering their typological analysis there are basically two types, beaker and bowl. Beakers are considered drinking vessels as they either display a legend or a mythological reference to drink or wine. Whereas a general consensus agrees that open bowl-form cups were hanging lamps (Whitehouse 1988, p.28) since the 1986 find of a diatreta bowl with copper alloy hanging attachments. It is clear these were luxury objects to be used in special occasions and spaces. The aim of this paper is to understand the space were socialisation and drinking took place and the importance of luxurious objects to adorn, display and use. The paper will also put forward the idea that the beaker shaped diatreta vessels, usually considered for drinking, could have been lamps that encouraged drinking and good will to the guests. This paper is structured to first consider an introduction to late luxury Roman glass and then analysing the typological shape of all, or most of the diatreta currently known; secondly, through assessment by the means of comparison, analyse the writings or decorations the vessels were endowed with. Thirdly, by describing and understanding the people and the space were these vessels would have been used, emphasise the beauty of illuminating such spaces with these vessels. According to Herodotus in his historical investigation â5th century-, dress habits and food regime are elements of extreme importance to understand a people (Caporusso et al. 2011, p.12). This idea is not only valid for Herodotusâ time but it is something anthropology uses time and again to explain different aspects in peopleâs way of life. Through food and its environment, the dining space, this paper will aim to put the cage cups into a social context in order to give emphasis to the hypothesis of light versus wine
Deep-sequencing reveals broad subtype-specific HCV resistance mutations associated with treatment failure
A percentage of hepatitis C virus (HCV)-infected patients fail direct acting antiviral (DAA)-based treatment regimens, often because of drug resistance-associated substitutions (RAS). The aim of this study was to characterize the resistance profile of a large cohort of patients failing DAA-based treatments, and investigate the relationship between HCV subtype and failure, as an aid to optimizing management of these patients. A new, standardized HCV-RAS testing protocol based on deep sequencing was designed and applied to 220 previously subtyped samples from patients failing DAA treatment, collected in 39 Spanish hospitals. The majority had received DAA-based interferon (IFN) a-free regimens; 79% had failed sofosbuvir-containing therapy. Genomic regions encoding the nonstructural protein (NS) 3, NS5A, and NS5B (DAA target regions) were analyzed using subtype-specific primers. Viral subtype distribution was as follows: genotype (G) 1, 62.7%; G3a, 21.4%; G4d, 12.3%; G2, 1.8%; and mixed infections 1.8%. Overall, 88.6% of patients carried at least 1 RAS, and 19% carried RAS at frequencies below 20% in the mutant spectrum. There were no differences in RAS selection between treatments with and without ribavirin. Regardless of the treatment received, each HCV subtype showed specific types of RAS. Of note, no RAS were detected in the target proteins of 18.6% of patients failing treatment, and 30.4% of patients had RAS in proteins that were not targets of the inhibitors they received. HCV patients failing DAA therapy showed a high diversity of RAS. Ribavirin use did not influence the type or number of RAS at failure. The subtype-specific pattern of RAS emergence underscores the importance of accurate HCV subtyping. The frequency of âextra-targetâ RAS suggests the need for RAS screening in all three DAA target regions

Gaia Early Data Release 3: The celestial reference frame (Gaia-CRF3)
Context. Gaia-CRF3 is the celestial reference frame for positions and proper motions in the third release of data from the Gaia mission, Gaia DR3 (and for the early third release, Gaia EDR3, which contains identical astrometric results). The reference frame is defined by the positions and proper motions at epoch 2016.0 for a specific set of extragalactic sources in the (E)DR3 catalogue. Aims. We describe the construction of Gaia-CRF3 and its properties in terms of the distributions in magnitude, colour, and astrometric quality. Methods. Compact extragalactic sources in Gaia DR3 were identified by positional cross-matching with 17 external catalogues of quasi-stellar objects (QSO) and active galactic nuclei (AGN), followed by astrometric filtering designed to remove stellar contaminants. Selecting a clean sample was favoured over including a higher number of extragalactic sources. For the final sample, the random and systematic errors in the proper motions are analysed, as well as the radio-optical offsets in position for sources in the third realisation of the International Celestial Reference Frame (ICRF3). Results. Gaia-CRF3 comprises about 1.6 million QSO-like sources, of which 1.2 million have five-parameter astrometric solutions in Gaia DR3 and 0.4 million have six-parameter solutions. The sources span the magnitude range G = 13-21 with a peak density at 20.6 mag, at which the typical positional uncertainty is about 1 mas. The proper motions show systematic errors on the level of 12 ÎŒas yr-1 on angular scales greater than 15 deg. For the 3142 optical counterparts of ICRF3 sources in the S/X frequency bands, the median offset from the radio positions is about 0.5 mas, but it exceeds 4 mas in either coordinate for 127 sources. We outline the future of Gaia-CRF in the next Gaia data releases. Appendices give further details on the external catalogues used, how to extract information about the Gaia-CRF3 sources, potential (Galactic) confusion sources, and the estimation of the spin and orientation of an astrometric solution
