Einige Bemerkungen zur Emanzipation des Frauenbildes in der deutschen und polnischen Phraseologie
2019
Phrasemes reflect habits and customs, traditions, historical facts, social life phenomena and cultural values of a given society. Phrasemes often “live” longer than the image they reflect. Women were and still are a subject of phrasemes. The aim of this paper is an answer to the question if the image of women arising from the Polish and German phraseology in the face of the transformations taking place in the last 40 years in the society has changed and if new phrasemes describing women of the 21st century appeared.
Dalla parte di Caino? Aspetti teorici, dati empirici, stereotipi e politiche di intervento sul caso degli uomini maltrattanti
2021
Partendo dai dati empirici raccolti nel corso di un progetto Prin su Rappresentazioni sociali della violenza sulle donne: il caso del femminicidio in Italia – e, in particolare, dai risultati emersi dallo studio sulle rappresentazioni del femminicidio nei procedimenti giudiziari – il saggio affronta il controverso tema del profilo dell’uomo maltrattante intorno al quale si concentrano stereotipi e timori sociali ma la cui conoscenza è un tassello indispensabile per affrontare – con il necessario “distacco analitico” – il fenomeno della violenza di genere, evitando derive esorcizzanti o altrettanto pericolosi scivoloni paternalistici, patologizzanti e moralizzanti. Il quesito centrale riguar…
Structure and optical properties of a monolayer single crystal of a cyanine dye
1992
Abstract Molecularly thin single crystals of a cyanine dye prepared by adsorption at a charged surfactant monolayer are studied by polarized optical spectroscopy and electron diffraction. Both techniques independently show a herringbone arrangement of the dye with the long axes of translationally inequivalent molecules forming an angle of 80°. The dye arranges in a primitive rectangular unit cell (a=21.2 A, b=6.14 A) adjacent to an epitaxially related hexagonal cell of the aliphatic tails of the surfactant.
<title>Selective filters for improvement of color discrimination</title>
2003
Colored filters have been used as possible aids for perception in case of congenital color vision abnormalities. Higher stimulation for L cones in one eye (red filter) and for M cones (green) in other eye acts as a simple method to interfere in human color vision processing. Influence on subjective and objective vision performances as binocular functions, fusion, stereopsis and color vision has been tested. Special colored glasses have been created, taking into account each subjects refraction for distance and tested for the 5 months adaption time. No negative influence on binocular functions, no changes of heterophoria and lowering in fusion ability and stereopsis have been stated due to u…
When virtual and real worlds coexist: Visualization and visual system affect spatial performance in augmented reality
2021
New visualization approaches are being actively developed aiming to mitigate the effect of vergence-accommodation conflict in stereoscopic augmented reality; however, high interindividual variability in spatial performance makes it difficult to predict user gain. To address this issue, we investigated the effects of consistent and inconsistent binocular and focus cues on perceptual matching in the stereoscopic environment of augmented reality using a head-mounted display that was driven in multifocal and single focal plane modes. Participants matched the distance of a real object with images projected at three viewing distances, concordant with the display focal planes when driven in the mu…
Communication between iron(II) building blocks in cooperative spin transition phenomena
2003
[EN] In the present article we discuss the cooperative nature of the spin crossover phenomenon in iron(II) complexes, providing a perspective of the state of the art in this area. The first aspect we discuss is the role of the intermolecular interactions, more precisely the ¿-interactions, in mononuclear complexes. We show that by playing with the nature of the ligands, aliphatic, aromatic, or extended aromatic, it is possible to create stronger cohesive forces and receive a more cooperative response from the compound. In the next step the singular family of bipyrimidine-bridged iron(II) dinuclear compounds is presented as the simplest example of polynuclear spin crossover complexes exhibit…
Optical and electrical properties of oriented thin films of oligomer containing betaine-type moiety in side chain
2005
Non-linear optical and electrical properties of polymer films obtained by dipole orientation of active units are reported. Novel polar oligomer with N-(indan-1,3-dion-2-yl)pyridinium betaine (IPB) as a side group is studied. Orientation of polar groups in oligomer thin films causes an increase of the photo-induced change of surface potential on irradiation in the region of photo-induced electron transfer (PIET) where the IPB group exhibits a reversible change of the value and sign of the dipole moment. At longer wavelengths, the value of the surface potential of the oligomer may be determined by transport of photogenerated charge carriers.
Howard–Dolman stereovision test at different opponent colour stimuli
2011
The purpose of this study was to investigate visual depth perception of real physical colour stimuli with red-green and blue-yellow opponency. We modified the Howard–Dolman stereotest where subjects should determine the closer of two bars emitting the light of definite colour placed in front of a CRT monitor served as colour background. Two-alternative forced-choice paradigms were used to determine depth perception threshold values. Thresholds close to 5–10 arcsec for luminance and colour contrast stimuli were revealed both for red-green and blue-yellow stimuli. A term, stereosensitivity – a reciprocal magnitude of the stereothreshold – was introduced to separately analyse luminance and col…
Diorganotin(IV) complexes ofD-galacturonic acid: solid-state and solution-phase structural study
2003
Three diorganotin(IV) complexes of D-galacturonic acid (H2GalA; R = Me, n-Bu, Ph), two of which are new derivatives (R = Me, Ph), have been synthesized and their solid-state and solution-phase investigated by IR, Mossbauer, 1H, 13C and 119Sn NMR spectroscopy. The FTIR data suggest that H2GalA, in the dialkyltin derivatives, behaves as a dianionic ligand, coordinating the tin(IV) atom through an ester-type carboxylate and deprotonated alcoholic hydroxo groups, whereas a bridging carboxylate occurs in the diphenyltin(IV) complex. Octahedral and trigonal bipyramidal local geometries on tin(IV) atoms are proposed for dialkyltin(IV)GalA and diphenyltin(IV)GalA complexes respectively on the basis…
Dzimtes stereotipu mazināšana mašīntulkošanā: mērķvalodas gramatiskās dzimtes projekcijas avotvalodā
2020
Tulkojot “The secretary asked for details.” no valodas bez gramatiskās dzimtes (angļu) uz valodu ar gramatisko dzimti (piemēram, latviešu), nepieciešams noteikt subjekta “the secretary” dzimumu. Ja teikuma līmenī nav nepieciešamās informācijas, to ne vienmēr ir iespējams izdarīt. Šādos gadījumos mašīntulkošanas sistēmas izvēlās biežāk sastopamos un līdz ar to dzimtes stereotipiem atbilstošos tulkojumu variantus (t.i. “sekretāre”). Darbā tiek piedāvāta mašīntulkošanas sistēmu apmācības metode, kur avotvalodas vārdiem ir tieši norādīta dzimtes pazīme (sieviešu vai vīriešu). Sistēmu apmācības dati tiek sagatavoti, projicējot mērķvalodas vārdu gramatiskās dzimtes uz avotvalodas vārdiem. Rezultā…
