Effect of explicit and implicit components of psychologists’ mental experience on their parental competence

The purpose of this research was to determine the effect of various components of psychologists’ mental experience (ME) on their parental competence (PC) when dealing with children of primary school age. We have distinguished three factors – professional attitude, professional competence and professional learning, dividing each into a number of components relating to explicit and implicit experience. For instance, explicit representation of professional attitude in terms of communication with children is a psychologist’s self-assessment scale, and implicit representation is a degree of openness of cognitive position as willingness to solve problems. Explicit representation of psychologist’s professional competence is his/her work experience in his/her major (school psychologist), and implicit representation is reflexivity of cognitive style built by competent professionals. Professional learning for psychologists takes two forms: explicit learning, which is a conscious acquisition of knowledge and skills through trainings and seminars, and implicit learning, which is undirected, for example, through research and writing articles. It has turned out that explicit and implicit components of mental experience have a different effect on such parameters of psychologists’ parental competence as feedback efficiency, level of feedback detail and predictability of feedback usefulness. In other words, we have established that professional mental experience of psychologists may shape up their parental competence, making it both high and low. It is important to know that implicit (and often unconscious) components of mental experience have as much effect as its explicit components. We believe that study of implicit components of professional learning may contribute to improvement of psychologists’ professional training and development of a professional’s mature personality.

Influence of s-d scattering on the electron density of states in ferromagnet/superconductor bilayer

We study the dependence of the electronic density of states (DOS) on the distance from the boundary for a ferromagnet/superconductor bilayer. We calculate the electron density of states in such structure taking into account the two-band model of the ferromagnet (FM) with conducting s and localized d electrons and a simple s-wave superconductor (SC). It is demonstrated that due to the electron s-d scattering in the ferromagnetic layer in the third order of s-d scattering parameter the oscillation of the density of states has larger period and more drastic decrease in comparison with the oscillation period for the electron density of states in the zero order.Comment: 5 pages, 3 figure

The volume of random simplices from elliptical distributions in high dimension

Random simplices and more general random convex bodies of dimension $p$ in $\mathbb{R}^n$ with $p\leq n$ are considered, which are generated by random vectors having an elliptical distribution. In the high-dimensional regime, that is, if $p\to\infty$ and $n\to\infty$ in such a way that $p/n\to\gamma\in(0,1)$, a central and a stable limit theorem for the logarithmic volume of random simplices and random convex bodies is shown. The result follows from a related central limit theorem for the log-determinant of $p\times n$ random matrices whose rows are copies of a random vector with an elliptical distribution, which is established as well.Comment: 25 page
