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…
Il diritto non scritto nel sistema della Convenzione europea dei diritti umani
2016
Il lavoro si occupa dei rapporti tra diritto internazionale generale e sistema della Cedu, affrontando in particolare il problema di capire se la Corte edu abbia fatto ricorso al modello tradizionalmente usato nella giurisprudenza internazionale per stabilire condizioni e modalità di funzionamento delle norme generali nel sistema o se abbia elaborato una concezione un modello autonomo. This paper discusses the relationship between customary international law and the ECHR. The focus is the question whether this problem has been handled by the European Court of Human Rights through the model of relationship between customary law and treaty law which is commonly used by international judges an…
Fast Computation by Subdivision of Multidimensional Splines and Their Applications
2016
We present theory and algorithms for fast explicit computations of uni- and multi-dimensional periodic splines of arbitrary order at triadic rational points and of splines of even order at diadic rational points. The algorithms use the forward and the inverse Fast Fourier transform (FFT). The implementation is as fast as FFT computation. The algorithms are based on binary and ternary subdivision of splines. Interpolating and smoothing splines are used for a sample rate convertor such as resolution upsampling of discrete-time signals and digital images and restoration of decimated images that were contaminated by noise. The performance of the rate conversion based spline is compared with the…
ON SOME GENERALIZATION OF SMOOTHING PROBLEMS
2015
The paper deals with the generalized smoothing problem in abstract Hilbert spaces. This generalized problem involves particular cases such as the interpolating problem, the smoothing problem with weights, the smoothing problem with obstacles, the problem on splines in convex sets and others. The theorem on the existence and characterization of a solution of the generalized problem is proved. It is shown how the theorem gives already known theorems in special cases as well as some new results.
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…
A sense of spacing: Toward a diffractive reading of organizational space
2022
This article explores how a diffractive methodology can enrich research on organizational space and the senses. Through the creation of interferences, a diffractive methodology directs attention to how differences in sensing are created in the ongoing production of space and what the effects of these are. By using examples from an ethnographic study of the Hub, a university-based entrepreneurship space designed to invoke positive “buzz”, the article illustrates how a diffractive methodology allows for the exploration of the sensory design of space and how it governs the possibilities of sensing among participants. The article contributes to organizational research by demonstrating how a di…
