Through space singlet-singlet and triplet-triplet energy transfers in cofacial bisporphyrins held by the carbazoyl spacer
2007
The through space singlet-singlet and triplet-triplet energy transfers in cofacial bis(etio-porphyrins) rigidly held by the carbazoyl spacer were investigated. The studies on singlet-singlet transfer, which operates via a Förster mechanism, were performed using the zinc porphyrin and free base chromophores as energy donor and acceptor, respectively, while the investigation on triplet-triplet processes was performed using the palladium porphyrin, and the zinc porphyrin and free base chromophores as donor and acceptors, respectively. The rate for singlet-singlet transfer ( k ET ( singlet )) is unexpectedly slower than that reported for other similar, rigidly held bisporphyrins such as H 2( D…
Recognition of briefly presented familiar and unfamiliar faces
2009
Early processing stages in the perception of familiar and unfamiliar faces were studied in four experiments by varying the type of available facial information in a four alternative forced choice recognition task. Both reaction time and recognition accuracy served as dependent measures. The observed data revealed an asymmetry in processing familiar and unfamiliar faces. A markedly weak inversion effect and strong blurring effect suggest a limited usage of spatial relations within early processing stages of unfamiliar faces. Recognition performance for whole familiar faces did not deteriorate due to blurring or the presentation of isolated internal features, suggesting a low level of represe…
Las columnas de Arturo Pérez-Reverte entre descortesía y virtud
2020
Impoliteness is a prevailing feature in Arturo Pérez-Reverte’s columns. Against all odds, it has a big argumentative effectiveness, since it allows the locutor to show an image of himself which is virtuous, that is a sincere, credible and, for this reason, persuasive. After all, as Aristotle states in his Rhetoric, persuasion depends on locutor’s ability to project an attractive ethos (self-image). Among the qualities that guarantees this attraction, the Stagirite includes the virtue, i.e. the speaker’s ability to tell frankly his/her opinions and ideas. In Pérez-Reverte’s columns, the realization of this quality is exactly what determines a frankness bordering sometimes on impoliteness. Ho…
Seju aizsedzoša reliģiska apģērba nēsāšanas aizlieguma juridiskie aspekti
2018
Maģistra darba nosaukums ir ’’Seju aizsedzoša reliģiska apģērba nēsāšanas aizlieguma juridiskie aspekti’’. Paredzot aizliegumu publiskās vietās nēsāt seju aizsedzošu apģērbu, var tikt ierobežotas personas tiesības uz reliģijas brīvības ārējo izpausmi, jo reliģijas brīvības ārējā izpausme ietver arī galvassegu nēsāšanu, kas it sevišķi ir attiecināms uz musulmaņu sievietēm. Šobrīd Latvijā tiek izstrādāts likums, ar kuru tiek plānots aizliegt publiskās vietās nēsāt seju aizsedzošu apģērbu. Tādējādi ir nepieciešams apzināt, izpētīt un izvērtēt tos juridiskos aspektus saskaņā ar kuriem šāds ierobežojums būtu atzīstams par tiesisku. Maģistra darba mērķis ir to juridisko aspektu noskaidrošana un i…
Latvijas Apdrošinātāju asociācijas nedzīvības apdrošināšanas biedru komunikācija sociālajā platformā Facebook
2022
Mūsdienās sociālie tīkli ir attīstījušies, līdz ar ko tie arī spēj sniegt dažādas priekšrocības uzņēmumiem kā efektīvāk parādīt savus produktus un kā darboties tirgū. Sociālais medijs Facebook piedāvā plašas iespējas darbojoties uzņēmumiem savās lapās. Facebook ir sociālā platforma kurā Latvijas Apdrošināšanas asociācijas nedzīvības apdrošināšanas biedri izvēlas veidot uzņēmuma lapas, lai sasniegtu lielāku mērķa auditoriju. Katram ir savas mediju mārketinga stratēģijas, tādēļ šī darba mērķis ir izpētīt nedzīvības apdrošinātāju komunikāciju sociālajā medijā Facebook. Balstoties uz aptauju rezultātiem un kontentanalīzes, tiks atklāta LAA nedzīvības apdrošinātāja veiksmīgākā komunikācija Faceb…
Modeling bismuth insertion in 1D hybrid lead halide TMSO(Pb x Bi y )I3 pseudo-perovskites
2022
Abstract The structures of the disordered 1D (pseudo-)perovskites of general TMSO(Pb x Bi y )I3 formulation [TMSO = (CH3)3SO+], obtained by doping the TMSOPbI3 species with Bi3+ ions, are investigated through the formulation of a statistical model of correlated disorder, which addresses the sequences of differently occupied BI6 face-sharing octahedra (B = Pb, Bi or vacant site) within ideally infinite [(BI3)−] n chains. The x-ray diffraction patterns simulated on the basis of the model are matched to the experimental traces, which show many broad peaks with awkward (nearly trapezoidal) shapes, under the assumption that the charge balance is fully accomplished within each chain. The analysis…

Automatic Processing of Changes in Facial Emotions in Dysphoria: A Magnetoencephalography Study
2018
It is not known to what extent the automatic encoding and change detection of peripherally presented facial emotion is altered in dysphoria. The negative bias in automatic face processing in particular has rarely been studied. We used magnetoencephalography (MEG) to record automatic brain responses to happy and sad faces in dysphoric (Beck’s Depression Inventory ≥ 13) and control participants. Stimuli were presented in a passive oddball condition, which allowed potential negative bias in dysphoria at different stages of face processing (M100, M170, and M300) and alterations of change detection (visual mismatch negativity, vMMN) to be investigated. The magnetic counterpart of the vMMN was el…
2014
Some years ago an improved design (the "complete design") was proposed to assess the composite face effect in terms of a congruency effect, defined as the performance difference for congruent and incongruent target to no-target relationships (Cheung et al., 2008). In a recent paper Rossion(2013) questioned whether the congruency effect was a valid hallmark of perceptual integration, because it may contain confounds with face-unspecific interference effects. Here we argue that the complete design is well-balanced and allows one to separate face-specific from face-unspecific effects. We used the complete design for a same/different composite stimulus matching task with face and non-face objec…
Why People Don’t Use Facebook Anymore? An Investigation Into the Relationship Between the Big Five Personality Traits and the Motivation to Leave Fac…
2020
This study linked the big five personality traits with motivational factors to leave Facebook based on a survey of 218 former Facebook users. The big five were related with eight main factors retrieved from existing literature. Results showed that neuroticism was positively related to addiction, banality, peer pressure, and privacy while conscientiousness was negatively related to peer pressure, addiction, annoyance, and emergence of new platforms. Openness was positively related with banality but negatively with addiction and peer pressure. Theoretical and practical interpretations are also discussed.
