Religious and spiritual motifs in the art of the patients of Nikkilä Hospital
2021
This article focuses on religiousness and spirituality in the art works of psychiatric patients of Nikkilä Hospital, Finland. The pictures analysed here belong to a collection held at the Helsinki City Museum and they were made during the twentieth century. The theoretical frame of the study is a cultural study of mental health. The collection is approached as presenting a specific kind of imagery which has connections not only to the personal history and diagnoses of the patients; their cultural context and hospital environment is also taken into account. The religiousness and spirituality of the Nikkilä collection are also compared with outsider art and examples of art history internation…
Ex Machina: Is Ava a Person?
2021
What does it mean to be a person? Is it possible to create an artificial person? In this essay, I consider the case of Ava, an advanced artificial general intelligence from the movie Ex Machina. I suggest we should interpret the movie as testing whether Ava is a person. I start out by discussing what it means to be a person, before I discuss whether Ava is such a person. I end by briefly looking at the ethics of the case of Ava and artificial personhood. I conclude, among some other things, that consciousness is a necessary requirement for personhood, and that one of the main obstacles for artificial personhood is artificial consciousness.
Posthumānisma domstarpības un Pigmaliona mīts Ričarda Pauersa romānā "Galatea 2,2"
2021
Tehnoloģijas, īpaši mākslīgais intelekts, strauji attīstās. Posthumānisms kā teorija noraida humānisma antropocentriskumu, kas uzskata cilvēku par Visuma centru. Līdz ar augošo mijiedarbību start tehnoloģijām un cilvēku, robežas starp tiem pamazām izzūd. Šī darba mērķis ir izpētīt attiecības starp cilvēku un tā radīto būtni Ričarda Pauersa romānā “Galatea 2,2”, intelektuālo mašīnu un cilvēka mijiedarbību posthumānisma kontekstā un tehnoloģiju spēju parādīt pašapziņu par spīti to bezķermeniskumam. Helēna ir posthumānisma ķermenis, kuru cilvēki ir radījuši ar cerību, ka tā spēs nokārtot Turinga testu. Helēna sāk izrādīt apziņu, kas palīdz tai izveido ciešas attiecības ar Pauersu.
Cloud screening with combined MERIS and AATSR images
2009
This paper presents a cloud screening algorithm based on ensemble methods that exploits the combined information from both MERIS and AATSR instruments on board ENVISAT in order to improve current cloud masking products for both sensors. The first step is to analyze the synergistic use of MERIS and AATSR images in order to extract some physically-based features increasing the separability of clouds and surface. Then, several artificial neural networks are trained using different sets of input features and different sets of training samples depending on acquisition and surface conditions. Finally, outputs of the trained neural networks are combined at the decision level to construct a more ac…
Some Personality Correlates of Business White-Collar Crime
2006
On presente dans cet article les resultats de la premiere etude transversale europeenne portant sur les dimensions de la personnalite en relation avec les delits financiers commis par les cols blancs. Ce travail est un prolongement de la recherche de Collin & Schmidt (1992) sur les delits des cols blancs aux Etats-Unis. Les donnees ont ete recoltees aupres de 150 cadres en poste dans des societes commerciales allemandes et de 76 delinquants en col blanc anciennement cadres. Les repondants ont rempli des echelles papier crayon mesurant l’hedonisme (l’Echelle de Valeurs de Schwartz), le sens des responsabilites (NEO-FFI), le narcissisme (DSM-III-R), la desirabilite sociale (Crowne & Marlowe),…
In silico and in vitro comparative analysis to select, validate and test SNPs for human identification.
2007
Abstract Background The recent advances in human genetics have recently provided new insights into phenotypic variation and genome variability. Current forensic DNA techniques involve the search for genetic similarities and differences between biological samples. Consequently the selection of ideal genomic biomarkers for human identification is crucial in order to ensure the highest stability and reproducibility of results. Results In the present study, we selected and validated 24 SNPs which are useful in human identification in 1,040 unrelated samples originating from three different populations (Italian, Benin Gulf and Mongolian). A Rigorous in silico selection of these markers provided …
CONSTRAINTS ON THE PROGENITOR SYSTEM AND THE ENVIRONS OF SN 2014J FROM DEEP RADIO OBSERVATIONS
2014
We report deep EVN and eMERLIN observations of the Type Ia SN 2014J in the nearby galaxy M 82. Our observations represent, together with JVLA observations of SNe 2011fe and 2014J, the most sensitive radio studies of Type Ia SNe ever. By combining data and a proper modeling of the radio emission, we constrain the mass-loss rate from the progenitor system of SN 2014J to $\dot{M} \lesssim 7.0\times 10^{-10}\, {\rm M_{\odot}\, yr^{-1}}$ (3-$\sigma$; for a wind speed of $100\, {\rm km s^{-1}}$). If the medium around the supernova is uniform, then $n_{\rm ISM} \lesssim 1.3 {\rm cm^3}$ (3-$\sigma$), which is the most stringent limit for the (uniform) density around a Type Ia SN. Our deep upper lim…
Modeling the shock-cloud interaction in SN 1006: unveiling the origin of nonthermal X-ray and gamma-ray emission
2016
The supernova remnant SN 1006 is a source of high-energy particles and its southwestern limb is interacting with a dense ambient cloud, thus being a promising region for gamma-ray hadronic emission. We aim at describing the physics and the nonthermal emission associated with the shock-cloud interaction to derive the physical parameters of the cloud (poorly constrained by the data analysis), to ascertain the origin of the observed spatial variations in the spectral properties of the X-ray synchrotron emission, and to predict spectral and morphological features of the resulting gamma-ray emission. We performed 3-D magnetohydrodynamic simulations modeling the evolution of SN 1006 and its inter…
Thermal emission, shock modification, and X-ray emitting ejecta in SN 1006
2009
Efficient particle acceleration can modify the structure of supernova remnants. In this context we present the results of the combined analysis of the XMM-Newton EPIC archive observations of SN 1006. We aim at describing the spatial distribution of the physical and chemical properties of the X-ray emitting plasma at the shock front. We investigate the contribution of thermal and non-thermal emission to the X-ray spectrum at the rim of the remnant to study how the acceleration processes affect the X-ray emitting plasma. We perform a spatially resolved spectral analysis on a set of regions covering the whole rim of the shell and we exploit the results of the spectral analysis to produce a cou…
