The Psychometric properties of the resilience scale (RS-14) in Lithuanian adolescents

2021

In the current study, we provided the evidence of satisfactory validity of the RS-14 scale in the Lithuanian adolescents’ sample (N = 1299; Mage = 14.24; SDage = 1.26), based on its internal structure, and relations to other variables. The results of the study indicated an acceptable model fit for a single-factor structure of the scale with a high internal consistency (McDonald’s omega = 0.89). We also confirmed the scalar measurement invariance across groups of adolescents in terms of their age (i.e., early and middle adolescence) and mental health profile as well as partial scalar gender invariance. Adolescents characterized by high levels of socio-emotional problems reported lower levels…

Centrum, peryferie i zależność ścieżkowa. Interpretacja teorii Immanuela Wallersteina w kategoriach path dependence

2016

Artykuł przedstawia zastosowanie koncepcji zależności ścieżkowej (path dependence) do analizy wybranych trajektorii rozwojowych krajów (gospodarek), które zostały omówione przez Immanuela Wallersteina w pracach na temat nowoczesnego systemu-świata. W tekście zaprezentowano podstawowe założenia zależności ścieżkowej jako zjawiska oraz jako koncepcji pozwalającej na interpretację związków przyczynowo-skutkowych w rozwoju technologii oraz w bardziej złożonych opisach rozwoju społeczno-historycznego. Następnie szczegółowej analizie poddano trzy wybrane przypadki trajektorii gospodarek w okresie powstawania nowoczesnego systemu-świata: Polski, Wenecji i Anglii.

α-Conotoxins EpI and AuIB switch subtype selectivity and activity in native versus recombinant nicotinic acetylcholine receptors

2003

The Xenopus laevis oocyte expression system was used to determine the activities of alpha-conotoxins EpI and the ribbon isomer of AuIB, on defined nicotinic acetylcholine receptors (nAChRs). In contrast to previous findings on intracardiac ganglion neurones, alpha-EpI showed no significant activity on oocyte-expressed alpha3beta4 and alpha3beta2 nAChRs but blocked the alpha7 nAChR with an IC50 value of 30 nM. A similar IC50 value (103 nM) was obtained on the alpha7/5HT3 chimeric receptor stably expressed in mammalian cells. Ribbon AuIB maintained its selectivity on oocyte-expressed alpha3beta4 receptors but unlike in native cells, where it was 10-fold more potent than native alpha-AuIB, had…
