Selecting significant respondents from large audience datasets: The case of the World Hobbit Project

2016

International projects, online questionnaires, or data mining techniques now allow audience researchers to gather very large and complex datasets. But whilst data collection capacity is hugely growing, qualitative analysis, conversely, becomes increasingly difficult to conduct. In this paper, I suggest a strategy that might allow the researcher to manage this complexity. The World Hobbit Project dataset (36,109 cases), including answers to both closed and open-ended questions, was used for this purpose. The strategy proposed here is based on between-methods sequential triangulation, and tries to combine statistical techniques (k-means clustering) with textual analysis. K-means clustering pe…

1.5Jy MOJAVE AGN sample and 3FGL data

2016

We use the complete MOJAVE 1.5Jy sample of active galactic nuclei (AGNs) to examine the gamma-ray detection statistics of the brightest radio-loud blazars in the northern sky. We find that 23% of these AGNs were not detected above 0.1GeV by the Fermi-LAT during the four-year 3FGL catalog period partly because of an instrumental selection effect and partly due to their lower Doppler boosting factors. Blazars with synchrotron peaks in their spectral energy distributions located below 10^13.4^Hz also tend to have high-energy peaks that lie below the 0.1GeV threshold of the LAT, and are thus less likely to be detected by Fermi. The non-detected AGNs in the 1.5Jy sample also have significantly l…

YSOs in DROXO (Deep rho Oph XMM obs.)

2011

X-rays from very young stars are powerful probes to investigate the mechanisms at work in the very first stages of the star formation and the origin of X-ray emission in very young stars. We present results from a 500ks long observation of the rho Ophiuchi cloud with a XMM-Newton large program named DROXO, aiming at studying the X-ray emission of deeply embedded young stellar objects (YSOs). Cone search capability for table J/A+A/519/A34/tablea1 (List of sources detected in the DROXO EPIC images) Cone search capability for table J/A+A/519/A34/tablea3 (ISOCAM YSOs (Bontemps et al. 2001, J/A+A/372/173) undetected in the DROXO field of view)

XMM Optical Monitor Survey of TMC

2007

The Optical Monitor (OM) on-board XMM-Newton obtained optical/ultraviolet data for the XMM-Newton Extended Survey of the Taurus Molecular Cloud (XEST), simultaneously with the X-ray detectors. With the XEST OM data, we study the optical and ultraviolet properties of TMC members, and to perform correlative studies between the X-ray and OM light curves. In particular, we aim to determine whether accretion plays a significant role in the optical/ultraviolet and X-ray emissions. The Neupert effect in stellar flares is also investigated. Coordinates, average count rates and magnitudes were extracted from OM images, together with light curves with low time resolution (a few kiloseconds). For a fe…

Radio-optical scrutiny of compact AGN

2010

We study the correlations between the VLBA (Very Long Baseline Array) radio emission at 15GHz, extended emission at 151MHz, and optical nuclear emission at 5100{AA} for a complete sample of 135 compact jets. We use the partial Kendall's tau correlation analysis to check the link between radio properties of parsec-scale jets and optical nuclear luminosities of host active galactic nuclei (AGN). Cone search capability for table J/A+A/520/A62/table3 (Optical and radio parameters of 135 AGN)

Field conversations as a data source in qualitative social research

2020

Sammendrag Denne artikkelen belyser feltsamtaler som forskningsverktøy. Feltsamtaler er ofte usynlige og underkommunisert i den vitenskapelige litteraturen. Samtalene lar seg vanskelig tallfeste og beskrive; de mangler tilsynelatende systematikk og framstår gjerne bare som hverdagslig prat. Med søkelys på konteksten for samtalen og samtalens rammer og regi setter artikkelen feltsamtalen inn et kvalitativt metodeunivers. Feltsamtalen plasserer vi i et kontinuum mellom det kvalitative intervjuet på den ene siden og alminnelig prat mellom forsker og informant på den andre. Ved hjelp av eksempler fra vår egen empiriske forskning diskuterer vi feltsamtalenes bidrag som datainnsamlingsverktøy. Vi…

Integrating Self-Reports and Electrodermal Activity (EDA) Measurement in Studying Emotions in Professional Learning

2022

Studies on emotions in learning have been mostly conducted through self-reporting questionnaires and interviews conducted after the learning situation, which seldom focus on professional workplace learning. Meanwhile, workplace and professional learning research has been introduced with emerging methods to capture the learning processes at multiple levels. Previous research on emotions has suggested that self-reports should be supplemented with psychophysiological data. Challenged by this, this chapter aims to present and discuss the integration of self-reported and psychophysiological data in studying emotions and professional learning. The empirical research data are obtained from five Fi…

Iedomu valodas: H.F. Lavkrafta grāmatas “Kthulhu aicinājums” un tās latviskā tulkojuma analīze

2020

Izdomu valodas ir paredzētas būt par neatliekamu un visai svarīgu daļu izdomu pasaulēm daiļliteratūrā (un ne tikai), un ir bieži izgudrotas ar nolūku padarīt izdomu pasaules ticamākas. Daudzi slaveni rakstnieki jau senos laikos ir iepazīstinājuši daiļliteratūras lasītājus ar savām izdomu valodām. Šis maģistra darbs ir par Hovarda Filipsa Lavkrafta izdomu valodu “R’lje”, kura pastāv viņa pat izdomātā pasaulē ar nosaukumu “Cthulhu Mythos”. Šo valodu var sastapt vairākās grāmatās, filmā un arī videospēlē, bet šis maģistra darbs būs vairāk koncentrēts uz to valodu, kura sastopama tikai grāmatās un videospēlē. Šajā pētījumā es analizēju Lavkrafta grāmatu “Kthulhu aicinājums”, izvērtēju šīs grāma…

Effets de quartier, effet de département : discrimination liée au lieu de résidence et accès à l'emploi

2013

L’objet de cette étude est de mesurer la discrimination à l’embauche à l’encontre des jeunes en Ile-de-France en raison du lieu de résidence en considérant plusieurs échelles spatiales de façon à distinguer l’effet de la réputation du département (Paris et la Seine-Saint-Denis), celui de la localité et celui du quartier. L’évaluation est réalisée sur données expérimentales auto-construites de testing selon un protocole permettant d’examiner les effets propres à chacune de ces trois échelles sur l’accès à l’emploi ainsi que leurs effets cumulés. On s’intéresse aux discriminations pour deux professions en tension du secteur de la restauration pour laquelle les discriminations devraient a prio…
