Adaptation to portuguese and initial validation of the O*NET interests profiler - short form in a sample of brazilian university students

The assessment of vocational interests is a central issue in career counseling. This study aimed to adapt to Brazilian Portuguese the O*NET Interests Profiler - Short Form using a sample of 603 Brazilian university students from 28 different undergraduate degree programs, and obtain evidences of validity and reliability for the instrument. Two different instruments resulted from this work. The instruments evaluate vocational interests according to the RIASEC model, which includes six dimensions (Realistic, Investigative, Artistic, Social, Enterprising and Conventional). This model proposes that the six dimensions can be organized in a hexagonal structure following the R-I-A-S-E-C order, where adjacent dimensions should be more strongly related to each other than non-adjacent dimensions. Validity evidence was obtained through Principal Components Analysis (PCA), Multidimensional Scaling (MDS), correlations between secondary concepts from the theoretical model, and contrasts between groups. PCA results were in accordance with theoretical expectations (differentiation of the six dimensions), while MDS results did not confirm the hexagonal structure. Other correlational results were in consonance with theoretical predictions. The contrasts between selected groups indicated concurrent validity of the instruments. Internal consistency indexes for each subscale were good. Overall results suggest the instruments have acceptable evidences of validity and reliability. Further studies are suggested in order to increase the suitability of the instruments.La evaluación de intereses vocacionales es un tema central en asesoramiento de carrera.

NGC 7469 as seen by MEGARA: new results from high-resolution IFU spectroscopy

We present our analysis of high-resolution (R ∼ 20 000) GTC/MEGARA integral-field unit spectroscopic observations, obtained during the commissioning run, in the inner region (12.5 arcsec × 11.3 arcsec) of the active galaxy NGC 7469, at spatial scales of 0.62 arcsec. We explore the kinematics, dynamics, ionization mechanisms, and oxygen abundances of the ionized gas, by modelling the H α-[N II] emission lines at high signal-to-noise (> 15) with multiple Gaussian components. MEGARA observations reveal, for the first time for NGC 7469, the presence of a very thin (20 pc) ionized gas disc supported by rotation (V/σ = 4.3), embedded in a thicker (222 pc), dynamically hotter (V/σ = 1.3) one. These discs nearly corotate with similar peak-to-peak velocities (163 versus 137 km s^(−1)), but with different average velocity dispersion (38 ± 1 versus 108 ± 4 km s^(−1)). The kinematics of both discs could be possibly perturbed by star-forming regions. We interpret the morphology and the kinematics of a third (broader) component (σ > 250 km s^(−1)) as suggestive of the presence of non-rotational turbulent motions possibly associated either to an outflow or to the lense. For the narrow component, the [N II]/H α ratios point to the star-formation as the dominant mechanism of ionization, being consistent with ionization from shocks in the case of the intermediate component. All components have roughly solar metallicity. In the nuclear region of NGC 7469, at r ≤ 1.85 arcsec, a very broad (FWHM = 2590 km s^(−1)) H α component is contributing (41 per cent) to the global H α-[N II] profile, being originated in the (unresolved) broad line region of the Seyfert 1.5 nucleus of NGC 7469

We estimated the gas metallicity using the direct method for oxygen, nitrogen and helium and found a mean value of 12+log(O/H)=8.03±0.06, and integrated electron density and temperature of ∼ 161 cm^(−3) and ∼ 15400 K, respectively. The metallicity distribution shows a large range of ∆(O/H) = 0.72 dex between the minimum and maximum (7.69±0.06 and 8.42±0.05) values, unusual in a dwarf starforming galaxy. We derived an integrated log(N/O) ratio of −1.51 ± 0.05 and found that both N/O and O/H correspond to a primary production of metals. Spatially resolved maps indicate that the gas appears to be photoionized by massive stars according to the diagnostic line ratios. Between the possible mechanisms to explain the starburst activity and the large variation of oxygen abundance in this galaxy, our data support a possible scenario where we are witnessing an ongoing interaction triggering multiple star-forming regions localized in two dominant clumps.Depto. de Física de la Tierra y AstrofísicaFac. de Ciencias FísicasTRUEConsejo Nacional de Ciencia y Tecnología (CONACyT, México)Universidad Complutense de MadridInstituto de Astrofísica, Óptica y Electrónica (INAOE, México)Instituto de Astrofísica de AndalucíaUniversidad Politécnica de MadridGRANTECAN S.AEuropean Regional Development Funds (ERDF), through Programa Operativo Canarias FEDER 2014-2020ANID Fondecyt RegularMinisterio de Ciencia e InnovaciónGobierno de Canarias through EU FEDER fundingViera y Clavijo Senior program funded by ACIISI and ULLMinisterio de Economía y Competitividad Project Estallidos6Ministerio de Economía y Competitividad Project Estallidos7Junta de Andalucía“Center of Excellence Severo Ochoa Program”pu

Spatially resolved analysis of neutralwWinds, stars, and ionized gas kinematics with MEGARA/GTC: new insights on the nearby galaxy UGC 10205

We present a comprehensive analysis of the multiphase structure of the interstellar medium (ISM) and the stellar kinematics in the edge-on nearby galaxy UGC 10205 using integral field spectroscopy (IFS) data taken with MultiEspectrógrafo en GTC de Alta Resolución para Astronomía (MEGARA) at the GTC. We explore both the neutral and the ionized gas phases using the interstellar Na I D doublet absorption (LR−V setup, R ∼ 6000) and the Hα emission line (HR−R setup, R ∼ 18000), respectively. The high-resolution data show the complexity of the Hα emission-line profile revealing the detection of up to three kinematically distinct gaseous components. Despite of this fact, a thin-disk model is able to reproduce the bulk of the ionized gas motions in the central regions of UGC 10205. The use of asymmetric drift corrections is needed to reconciliate the ionized and the stellar velocity rotation curves. We also report the detection of outflowing neutral gas material blueshifted by ∼ 87 km s^(−1) . The main physical properties that describe the observed outflow are a total mass M_(out) = (4.55 ± 0.06) × 10^(7) Mʘ and a coldgas mass outflow rate M_(out) = 0.78 0.03 Mʘ yr^(−1) . This work points out the necessity of exploiting highresolution IFS data to understand the multiphase components of the ISM and the multiple kinematical components in the central regions of nearby galaxies

Escala de motivación para el aprendizaje en universitarios : versión abreviada

A avaliação da motivação para aprender é um aspecto relevante em contextos educacionais, pois a motivação pode influenciar o engajamento dos estudantes, sua aprendizagem e seu desempenho em tarefas acadêmicas. O objetivo deste estudo foi propor uma versão breve da Escala de Motivação para Aprendizagem em Universitários (EMAPRE-U Breve). A EMAPRE-U é uma escala de 28 itens que avalia três dimensões motivacionais: meta aprender, meta performance-aproximação e meta performance-evitação. Participaram do estudo 525 universitários do primeiro ano de graduação de uma universidade pública. Através de análises fatoriais exploratórias e de conteúdo dos itens chegou-se a uma versão com 15 itens. Análises fatoriais confirmatórias e de correlação com construtos relacionados forneceram evidências de validade para a medida breve, e indicaram um bom ajuste dos dados ao modelo trifatorial. Os resultados sugerem que o instrumento tem o potencial de contribuir para a avaliação da motivação para aprendizagem na educação superior, ainda que aprimoramentos possam ser feitos no futuro.The assessment of motivation to learn is a relevant aspect in educational contexts as motivation can influence student engagement, learning, and performance in academic tasks. The aim of this study was to propose a brief version of the Motivation Scale for Learning in University Students (EMAPRE-U Brief). The EMAPRE-U is a 28-item scale that assesses three motivational dimensions: the learning goal, the performance-approach goal, and the performance-avoidance goal. The study included 525 first-year undergraduate students at a public university. Through exploratory factor analysis and item content analysis, a 15-item version was developed. Confirmatory factor analysis and correlation with theoretically related constructs provided evidence of validity for the brief measure and indicated a good fit of the data to the three-factor model. The results suggest that the instrument has the potential to contribute to the assessment of motivation for learning in higher education, although improvements could be made in the future.La evaluación de la motivación para aprender es un aspecto relevante en los contextos educativos, ya que la motivación puede influir en el compromiso, aprendizaje y desempeño del estudiante en las tareas académicas.

MEGARA-GTC stellar spectral library: I

MEGARA (Multi Espectrografo en GTC de Alta Resolucion para Astronomia) is an optical (3650-9750 Å), fibre-fed, medium-high spectral resolution (R = 6000, 12 000 and 20 000) instrument for the Gran Telescopio CANARIAS (GTC) 10.4-m telescope, commissioned in the summer of 2017, and currently in operation. The scientific exploitation of MEGARA requires a stellar spectra library to interpret galaxy data and to estimate the contribution of the stellar populations. In this paper, we introduce the MEGARA-GTC spectral library, detailing the rationale behind the building of this catalogue. We present the spectra of 97 stars (21 individual stars and 56 members of the globular cluster M15, which are both subsamples taken during the commissioning runs, and 20 stars from our ongoing GTC Open-Time programme). The spectra have R = 20 000 in the HR-R and HR-I set-ups, centred at 6563 and 8633 Å, respectively. We describe the procedures to reduce and analyse the data. Then, we determine the best-fitting theoretical models to each spectrum through a χ^(2) minimization technique, to derive the stellar physical parameters, and we discuss the results. We have also measured some absorption lines and indices. Finally, we introduce our project to complete the library and the data base in order to make the spectra available to the community

A new insight of AGC 198691 (Leoncino) galaxy with MEGARA at the GTC

We describe the observations of the low metallicity nearby galaxy AGC 198691 (Leoncino Dwarf) obtained with the Integral Field Unit of the instrument MEGARA at the Gran Telescopio Canarias. The observations cover the wavelength ranges 4304-5198 Aand 6098-7306 Awith a resolving power R approximate to 6000. We present 2D maps of the ionized gas, deriving the extension of the H II region and gas kinematics from the observed emission lines. We have not found any evidence of recent gas infall or loss of metals by means of outflows. This result is supported by the closed-box model predictions, consistent with the oxygen abundance found by other authors in this galaxy and points towards Leoncino being a genuine XMD galaxy. We present for the first time spatially resolved spectroscopy allowing the detailed study of a star-forming region. We use POPSTAR + CLOUDY models to simulate the emission-line spectrum. We find that the central emission-line spectrum can be explained by a single young ionizing cluster with an age of approximate to 3.5 +/- 0.5 Myr and a stellar mass of approximate to 2 x10(3) M-circle dot. However, the radial profiles of [O III].5007Aand the Balmer lines in emission demand photoionization by clusters of different ages between 3.5 and 6.5 Myr that might respond either to the evolution of a single cluster evolving along the cooling time of the nebula (approximate to 3 Myr at the metallicity of Leoncino, Z approximate to 0.0004) or to mass segregation of the cluster, being both scenarios consistent with the observed equivalent widths of the Balmer lines

High-resolution MEGARA Integral-field Unit Spectroscopy and Structural Analysis of a Fast-rotating, Disky Bulge in NGC 7025

Disky bulges in spiral galaxies are commonly thought to form out of disk materials (mainly) via bar-driven secular processes. They are structurally and dynamically distinct from “classical bulges,” which are built in violent merger events. We use high-resolution GTC/MEGARA integral-field unit spectroscopic observations of the Sa galaxy NGC 7025, obtained during the MEGARA commissioning run, together with detailed 1D and 2D decompositions of this galaxy’s Sloan Digital Sky Survey i-band data to investigate the formation of its disky (bulge) component, which makes up ∼30% of the total galaxy light. With a Sérsic index n ~ 1.80 0.24, a half-light radius R_(e) ~ 1.70 0.43 kpc, and stellar mass M_(*) ~ (4.34 1.70) x 10^(10)M_(☉), this bulge dominates the galaxy light distribution in the inner R ~ 15 (∼4.7 kpc). Measuring the spins (λ) and ellipticities (Є) enclosed within nine different circular apertures with radii R ≤ R_(e), we show that the bulge, which exhibits a spin track of outwardly rising λ and Є, is a fast rotator for all the apertures considered. Our findings suggest that this inner disky component is a pseudo-bulge, consistent with the stellar and dust spiral patterns seen in the galaxy down to the innermost regions but in contrast to the classical bulge interpretation favored in the past. We propose that a secular process involving the tightly wound stellar spiral arms of NGC 7025 may be driving gas and stars out of the disk into the inner regions of the galaxy, building up the massive pseudo-bulge

Mapping the ionized gas of the metal-poor HII galaxy PHL 293B with MEGARA

Here we report the first spatially resolved spectroscopic study for the galaxy PHL 293B using the high-resolution GTC/MEGARA integral field unit (IFU). PHL 293B is a local, extremely metal-poor, high ionization galaxy. This makes PHL 293B an excellent analogue for galaxies in the early Universe. The MEGARA aperture (∼ 12.5” × 11.3”) covers the entire PHL 293B main body and its far-reaching ionized gas. We created and discussed maps of all relevant emission lines, line ratios and physical-chemical properties of the ionized ISM. The narrow emission gas appears to be ionized mainly by massive stars according to the observed diganostic line ratios, regardless of the position across the MEGARA aperture. We detected low intensity broad emission components and blueshifted absorptions in the Balmer lines (Hα,Hβ) which are located in the brightest zone of the galaxy ISM. A chemically homogeneity, across hundreds of parsecs, is observed in O/H. We take the oxygen abundance 12+log (O/H) = 7.64 ± 0.06 derived from the PHL 293B integrated spectrum as the representative metallicity for the galaxy. Our IFU data reveal for the first time that the nebular HeIIλ4686 emission from PHL 293B is spatially extended and coincident with the ionizing stellar cluster, and allow us to compute its absolute HeII ionizing photon flux. Wolf-Rayet bumps are not detected excluding therefore Wolf-Rayet stars as the main HeII excitation source. The origin of the nebular HeIIλ4686 is discussed
