Academic and personal development of an individual in the system of formal education

The study aims at revealing interactions within the complex set of factors contributing to individual academic and personal development, based on the longitudinal study of the representative sample of Estonian schools and Brazilian-Estonian cross-cultural study of adults with different levels of education, including a sample of adults with no formal education. In the interdisciplinary study, descriptive and experimental data are collected to analyze key factors affecting the development. The relationships between factors and their change in time will be explored. In addition to common research methods, a combination of micro- and macrogenetic, variable-based and qualitative descriptions, and group- and person-oriented methods will be used (still rare in educational studies).

Developing Test Battery for Assessing Basic School Students’ Psychological Processes and Educating Support Specialists

We compose and pilot the computer-based battery of tests for school psychologists for assessing students’ psychological processes and personality. This widens the possibilities to support the development of students with special educational needs.  We proceed from the research carried out in earlier projects in Tallinn University. As a result of these studies, we have developed cognitive and personality tests and examined their psychometric properties. In this project, we additionally develop tests to cover all age ranges and psychological variables. As a result, psychologists will have tests, their manuals and grade-based norms.  We educate other personnel in Rajaleidja regional youth guidance centres in the areas of child development, assessment, and support, and psychologists in skills of using tests and interpreting the results. More information.

Development of yeast-derived brewing additives

The aim of the project is to develop new kettle and beer fining agents and foam active materials (foam stabilizers) on the basis of baker’s yeast biomass.

Nonlinear Processes at Mesoscale Plasma-Materials Interactive Systems

This project is focused on the study of generation of defects in materials due to dense plasma interaction with armor and construction materials in different types of fusion devices. ln the research the following fields are of interest. First, investigation of how different materials (different tungsten grades and alloys, ceramics etc) can withstand the pulsed plasma and heat flows by using dense plasma devices as plasma accelerators. The second direction involves analysis of the role of different types of noises in the generation of defects in crystalline materials, which can be considered as an ensemble of oscillators. Experimental investigations show that in plasma-material interaction the material is affected not only by the heat flow, but also by the shock wave. Theoretical investigations indicate that a shock wave, together with other damage sources (heat flow as white noise) may lead to a significant increase of damages, and qualitatively different damages, than different sources (heat and shock wave) separately taken. ln the project the role of different factors in the generation of defects in a material is going to be estimated.

Dynamical properties of systems described by a generalized Langevin equation with a multiplicative noise

The investigation addresses the influence of multiplicative noise on the dynamical behavior of systems described by a generalized Langevin equation. The research will be focused on two basic problems. First, the combined effect of the memory time of a viscoelastic medium and a multiplicative noise (white and colored noises) will be studied in order to find out those regions in the space of system parameters where noise-induced qualitative transitions in system dynamics can be expected to occur. At that the noise models environmental fluctuations on the dynamics of Brownian particles trapped in a harmonic potential well. Second, the effect of anomalous diffusion on the dynamics of some multiplicative noise driven nonlinear systems (especially, models of predator--prey communities subjected to colored environmental fluctuations), in order to determine the physical conditions for the occurrence of Hopf bifurcations in the studied model systems. Expected results. A theoretical framework for analyzing stochastic data from single-particle tracking in viscoelastic media under the influence of a trapping potential will be developed. Also, establishment of the criteria that enable the researcher to distinguish noises of different physical origin in active microrheology experiments can be expected. We believe that a clearing up of the co-operative effects caused by interaction between multiplicative noise and viscoelastic memory opens up new possibilities of interpretation of the obtained data from microrheology experiments in viscoelastic media using a trapping potential, particularly, in biological applications, where the issues of memory and multiplicative noise can be crucial.

Baltic Info Campaign on Hazardous Substances (LIFE 10 INF/EE/108) is co-financed with the contribution of the LIFE+ financial instrument of the European Community.

We trained future teachers to carry out educational work at schools about dangerous substances in our environment. Young teachers bring knowledge of these students as the target audience. Our young teachers taught the subject in three classes, each class has 25 students, 75 students all together. For 20 teachers the total will be 1,500 students in a year, 3000 students in two years. The activities and results of the project: 1) training materials and programs; 2) teacher trainings for students; 3) general education student teaching; 4) students' self- analysis and evaluation for the work.

The main contibution of Tallinn University was the handbook for teachers "Think before you buy" and an example of the lesson structure.
