La valutazione neuropsicologica tra significatività statistica e clinica

2008

Aspetti statistici e clinici pervadono tutte le fasi della valutazione neuropsicologica, dalla scelta dei test alla loro restituzione. Il presente articolo, utilizzando i dati di due ricerche come esempio, mette in evidenza l’importanza di ognuno dei due aspetti e di come questi influenzino le diverse fasi del processo di valutazione neuropsicologica e soprattutto la decisione finale e l’eventuale intervento.

Revealing Employer’s Name in Social Networks

2017

Abstract The research investigates the question of the importance of mentioning the name of the employer in online and offline social networks. The exchange of information is an important part of social networks and social capital theory. Companies can use the networks of their employees to recruit new hires and to check habits and interests of likely new employees. To do that, the employee has to mention the name of the company in these social networks. The paper compares different real social networks used by family and friends and private and business social network sites (SNSs) as online social networks and compares the differences between men and women. The empirical research has been …

Theoretical profiles of the Mg + resonance lines perturbed by collisions with He

2016

International audience; The effects of collision broadening by He are central to understanding the opacity of cool stellar atmospheres. Aims. DZ white dwarfs show metal lines which are, in many cases, believed to come from some rocky material, a remnant of a former exoplanetary system. The analysis of the Mg + resonance lines is a valuable method to determine the chemical abundances in these systems. Methods. Unified profiles of the strongest of the UV lines of Mg + have been calculated in the semi-classical approach using very recent ab initio potential energies. Results. We present the first theoretical line profile calculations of the resonance lines of Mg + that have been perturbed by h…

Silesian Texans – przyczynek do relacji o stanie zachowania muzycznej kultury

2019

Śląscy Teksańczycy, od ponad 150 lat mieszkający w okolicach San Antonio w Teksasie, to dziś grupa szacowana przez niektórych badaczy na ok. 200 tysięcy (1%) mieszkańców tego stanu. Osie-dlali się zwykle grupowo, w przeciwieństwie do tzw. emigrantów brazylijskich z podobnego czasu. Tak powstały i istnieją do dziś osady o nazwach: Panna Maria (tu się wszystko zaczęło), Cesto-chowa, St. Hedwig, Kościuszko, Bandera i inne. Historię osadnictwa, losów rodzin, zachowania języka i kultury materialnej ujmują publikacje, niejednokrotnie niezwykle szczegółowe. Trudno podobny sąd wyrazić o badaniach stanu zachowania kultury muzycznej. Jednocześnie szczątkowe dane, zebrane niejednokrotnie niejako przy …

Half-width plots, a simple tool to predict peak shape, reveal column kinetics and characterise chromatographic columns in liquid chromatography: Stat…

2013

Peak profiles in chromatography are characterised by their height, position, width and asymmetry; the two latter depend on the values of the left and right peak half-widths. Simple correlations have been found between the peak half-widths and the retention times. The representation of such correlations has been called half-width plots. For isocratic elution, the plots are parabolic, although often, the parabolas can be approximated to straight-lines. The plots can be obtained with the half-widths/retention time data for a set of solutes experiencing the same kinetics, eluted with a mobile phase at fixed or varying composition. When the analysed solutes experience different resistance to mas…

XMM-Newton detects a relativistically broadened iron line in the spectrum of the ms X-ray pulsar SAX J1808.4-3658

2008

We report on a 63-ks long XMM-Newton observation of the accreting millisecond pulsar SAX J1808.4-3658 during the latest X-ray outburst which started on September 21st 2008. The pn spectrum shows a highly significant emission line in the energy band where the iron K-alpha line is expected, and which we identify as emission from neutral (or mildly ionized) iron. The line profile appears to be quite broad (more than 1 keV FWHM) and asymmetric; the most probable explanation for this profile is Doppler and relativistic broadening from the inner accretion disc. From a fit with a diskline profile we find an inner radius of the disc of 8.7^(+3.7)_(-2.7) R_g, corresponding to 18.0^(+7.6)_(-5.6) km f…

Large-scale normal fluid circulation in helium superflows

2017

We perform fully-coupled numerical simulations of helium II pure superflows in a channel, with vortex- line density typical of experiments. Peculiar to our model is the computation of the back-reaction of the superfluid vortex motion on the normal fluid and the presence of solid boundaries. We recover the uniform vortex-line density experimentally measured employing second sound resonators and we show that pure superflow in helium II is associated with a large-scale circulation of the normal fluid which can be detected using existing particle-tracking visualization techniques.

A relativistic iron emission line from the neutron star low-mass X-ray binary GX 3+1

2012

We present the results of a spectroscopic study of the Fe K{\alpha} emission of the persistent neutron-star atoll low-mass X-ray binary and type I X-ray burster GX 3+1 with the EPIC-PN on board XMM-Newton. The source shows a flux modulation over several years and we observed it during its fainter phase, which corresponds to an X-ray luminosity of Lx~10^37 ergs/s. When fitted with a two-component model, the X-ray spectrum shows broad residuals at \sim6-7 keV that can be ascribed to an iron K{\alpha} fluorescence line. In addition, lower energy features are observed at \sim3.3 keV, \sim3.9 keV and might originate from Ar XVIII and Ca XIX. The broad iron line feature is well fitted with a rela…
