Elevers oppfatning av lærers tilbakemeldingspraksis: om sammenheng mellom graden av VfL-praksis og elevenes opplevde nytte av lærers skriftlige tilbakemeldinger i skriftlig norsk
Authors: Eriksen Harald 
Published: November 2017

Formålet med denne studien var å undersøke elevers opplevde nytte av norsklærerens tilbakemeldingspraksis i skriftlig norsk. På bakgrunn av omfattende internasjonal forskning innen feltet ‘Vurdering for læring’ (VfL) er det i denne studien utviklet teoridrevne hypoteser som testes ved å analysere et datasett fra videregående skole. Hypotesene er at elevene oppfatter lærers tilbakemelding som mer nyttig hvis den 1) retter seg mot målet med opplæringen, 2) gir elevene informasjon via en forklaring eller instruks om hvordan de skal komme nærmere målet og 3) at lærer legger til rette for bruk av tilbakemeldingen. Strukturell likningsmodellering (SEM) av resultater fra en spørreundersøkelse blant elever (N = 213) er brukt som metode til å estimere forholdet mellom de fire latente variablene kriterier, forklaring, bruk og nytte (avhengig variabel). SEM er brukt fordi metoden egner seg til å undersøke sammenhenger i komplekse datasett. Funn er at læreres forklaringer på hvordan elevene skal forbedre seg skriftlig, er positivt statistisk assosiert med opplevd nytte. Et mer overraskende funn er at lærerens tilrettelegging for bruk av tilbakemeldinger ikke er signifikant assosiert med opplevd nytte. Resultatene blir diskutert i artikkelen. English abstract Students' Perception of Teachers' Assessment Practice: On the Link Between the Degree of Assessment for Learning Practice and Students' Conception of the Benefit of Teachers' Written Assessments in Written Norwegian The aim of the study was to explore student’s perceived usefulness of their Norwegian Language arts-teacher’s feedback practices in written Norwegian. On the basis of extended international research within the field of ‘Assessment for learning’ a set of theory-driven hypothesis have been developed and tested through analyses of data from a survey conducted in upper secondary school. According to theory students should perceive feedback from the teacher as useful if 1) it’s aimed towards the goals of the learning sequence, 2) provides information of how the student can reduce the gap between her/his own performance and the desired performance and 3) that the teacher facilitates further use of the feedback information in the learning process. Structural equation modelling (SEM) of results from the survey among students (N = 213) is used as method to estimate the relations between the four latent variables criteria, explanation, use and usefulness (dependent variable). SEM is chosen, as the method is suitable for investigating associations in complex data. Findings indicate that if the teacher, as perceived by the students, provides explanations on how to reduce the gap between performance and desired performance this is positively associated with usefulness. More surprisingly, the student’s perceptions of the teacher’s facilitation of use of feedback information are not significantly associated with perceived usefulness. Results are discussed in the article.

Abstract
This work attempts to quantitatively describe the microstructural evolution in a new commercial 6××× aluminum alloy developed in an industrial laboratory (Al-0.87Si-0.81Mg-0.51Zn-0.46Cu-0.19Fe-0.09Mn, in wt.%), during solidification by using the phase-field simulation supported by experimental measurements. Coupling to the CALPHAD thermodynamic and atomic mobility databases is attained for providing energy and diffusivity information during the phase-field simulation. Two different resolutions are used in order to resolve the primary α-(Al) dendrite and the faceted β-AlFeSi eutectic phase in the phase-field simulations. The phase-field simulated microstructure morphology is verified by experimental results. Moreover, the microsegregation and back-diffusion phenomena in the primary α-(Al) dendrite are also analyzed.

Abstract
Despite more than 20 years since the discovery of the first gas giant planet with an anomalously large radius, the mechanism for planet inflation remains unknown. Here, we report the discovery of K2-132b, an inflated gas giant planet found with the NASA K2 Mission, and a revised mass for another inflated planet, K2-97b. These planets orbit on ≈9 day orbits around host stars that recently evolved into red giants. We constrain the irradiation history of these planets using models constrained by asteroseismology and Keck/High Resolution Echelle Spectrometer spectroscopy and radial velocity measurements. We measure planet radii of 1.31 ± 0.11 R
J and 1.30 ± 0.07 R
J, respectively. These radii are typical for planets receiving the current irradiation, but not the former, zero age main-sequence irradiation of these planets. This suggests that the current sizes of these planets are directly correlated to their current irradiation. Our precise constraints of the masses and radii of the stars and planets in these systems allow us to constrain the planetary heating efficiency of both systems as

. These results are consistent with a planet re-inflation scenario, but suggest that the efficiency of planet re-inflation may be lower than previously theorized. Finally, we discuss the agreement within 10% of the stellar masses and radii, and the planet masses, radii, and orbital periods of both systems, and speculate that this may be due to selection bias in searching for planets around evolved stars.
Radiative Magnetic Reconnection Near Accreting Black Holes
Authors: Beloborodov Andrei M. 
Published: November 2017

Abstract
A radiative mechanism is proposed for magnetic flares near luminous accreting black holes. It is based on recent first-principle simulations of magnetic reconnection, which show a hierarchical chain of fast-moving plasmoids. The reconnection occurs in a compact region (comparable to the black hole radius), and the chain experiences fast Compton cooling accompanied by electron–positron pair creation. The distribution of plasmoid speeds is shaped by radiative losses, and the self-regulated chain radiates its energy in hard X-rays. The mechanism is illustrated by Monte-Carlo simulations of the transfer of seed soft photons through the reconnection layer. The emerging radiation spectrum has a cutoff near 100 keV similar to the hard-state spectra of X-ray binaries and AGN. We discuss how the chain cooling differs from previous phenomenological emission models, and suggest that it can explain the hard X-ray activity of accreting black holes from first principles. Particles accelerated at the X-points of the chain produce an additional high-energy component, explaining the “hybrid Comptonization” observed in Cyg X-1.

Abstract
We present the ionized gas properties of infrared (IR)-bright dust-obscured galaxies (DOGs) that show an extreme optical/IR color,

, selected with the Sloan Digital Sky Survey (SDSS) and Wide-field Infrared Survey Explorer (WISE). For 36 IR-bright DOGs that show [O iii]λ5007 emission in the SDSS spectra, we performed a detailed spectral analysis to investigate their ionized gas properties. In particular, we measured the velocity offset (the velocity with respect to the systemic velocity measured from the stellar absorption lines) and the velocity dispersion of the [O iii] line. We found that the derived velocity offset and dispersion of most IR-bright DOGs are larger than those of Seyfert 2 galaxies (Sy2s) at

, meaning that the IR-bright DOGs show relatively strong outflows compared to Sy2s. This can be explained by the difference in IR luminosity contributed from active galactic nuclei,

(AGN), because we found that (i)

(AGN) correlates with the velocity offset and dispersion of [O iii] and (ii) our IR-bright DOG sample has larger

(AGN) than Sy2s. Nevertheless, the fact that about 75% IR-bright DOGs have a large (>300 km s−1) velocity dispersion, which is a larger fraction compared to other AGN populations, suggests that IR-bright DOGs are good laboratories to investigate AGN feedback. The velocity offset and dispersion of [O iii] and [Ne iii]λ3869 are larger than those of [O ii]λ3727, which indicates that the highly ionized gas tends to show stronger outflows.

Abstract
We present a census of variable stars in six M31 dwarf spheroidal satellites observed with the Hubble Space Telescope. We detect 870 RR Lyrae (RRL) stars in the fields of And I (296), II (251), III (111), XV (117), XVI (8), and XXVIII (87). We also detect a total of 15 Anomalous Cepheids, three eclipsing binaries, and seven field RRL stars compatible with being members of the M31 halo or the Giant Stellar Stream. We derive robust and homogeneous distances to the six galaxies using different methods based on the properties of the RRL stars. Working with the up-to-date set of Period-Wesenheit (I, B–I) relations published by Marconi et al., we obtain distance moduli of μ
0 = [24.49, 24.16, 24.36, 24.42, 23.70, 24.43] mag (respectively), with systematic uncertainties of 0.08 mag and statistical uncertainties <0.11 mag. We have considered an enlarged sample of 16 M31 satellites with published variability studies, and compared their pulsational observables (e.g., periods and amplitudes) with those of 15 Milky Way satellites for which similar data are available. The properties of the (strictly old) RRL in both satellite systems do not show any significant difference. In particular, we found a strikingly similar correlation between the mean period distribution of the fundamental RRL pulsators (RRab) and the mean metallicities of the galaxies. This indicates that the old RRL progenitors were similar at the early stage in the two environments, suggesting very similar characteristics for the earliest stages of evolution of both satellite systems.
Biases in Metallicity Measurements from Global Galaxy Spectra: The Effects of Flux Weighting and Diffuse Ionized Gas Contamination

Published: November 2017

Abstract
Galaxy metallicity scaling relations provide a powerful tool for understanding galaxy evolution, but obtaining unbiased global galaxy gas-phase oxygen abundances requires proper treatment of the various line-emitting sources within spectroscopic apertures. We present a model framework that treats galaxies as ensembles of H ii and diffuse ionized gas (DIG) regions of varying metallicities. These models are based upon empirical relations between line ratios and electron temperature for H ii regions, and DIG strong-line ratio relations from SDSS-IV MaNGA IFU data. Flux-weighting effects and DIG contamination can significantly affect properties inferred from global galaxy spectra, biasing metallicity estimates by more than 0.3 dex in some cases. We use observationally motivated inputs to construct a model matched to typical local star-forming galaxies, and quantify the biases in strong-line ratios, electron temperatures, and direct-method metallicities as inferred from global galaxy spectra relative to the median values of the H ii region distributions in each galaxy. We also provide a generalized set of models that can be applied to individual galaxies or galaxy samples in atypical regions of parameter space. We use these models to correct for the effects of flux-weighting and DIG contamination in the local direct-method mass–metallicity and fundamental metallicity relations, and in the mass–metallicity relation based on strong-line metallicities. Future photoionization models of galaxy line emission need to include DIG emission and represent galaxies as ensembles of emitting regions with varying metallicity, instead of as single H ii regions with effective properties, in order to obtain unbiased estimates of key underlying physical properties.
