For several years now, noticeable has been a significant increase in the interest of psychologists – practitioners and scientists, of parents and teachers in the issues of dyslexia, dyscalculia, and ...other developmental disorders. Specific learning difficulties constitute one of the most prevalent causes of reporting children to psychological and pedagogic outpatient departments. The results of the performed studies enable inter- and intra-group comparisons as well as a global analysis of the structure of intellectual development in children with various learning difficulties. This leads to interesting conclusions and allows for comprehensive scientific discussions. The subject of the article is presentation of the results of studies and conclusions formulated according to them, about the structure of intellectual development of children with learning difficulties diagnosed in two psychological-pedagogic outpatient departments in Lublin region (Psychological-Pedagogic Outpatient Department No 5 in Lublin and PsychologicalPedagogic Outpatient Department No 2 in Zamość). Analysed were the results of the WISC-R scale obtained by schoolchildren from forms IV-VI of elementary schools and junior secondary schools in Lublin and schools of Zamość county. As scholastic difficulties constitute quite a comprehensive term, generally perceived as problems in acquisition of information and mastering school skills, in our study we take into account the following three groups of schoolchildren: with developmental dyslexia, intelligence lower than average, and specific disorders in arithmetic skills. The performed analyses are aimed at familiarization with the developmental level of the schoolchildren’s cognitive functions and their intellectual skills structure based on a three-factor analysis. Our studies continue earlier analyses, including more comprehensive research areas with larger groups.
In this article we present analytical solutions of the single and pair pulse time evolution of a plastic neocortical synapse described by the TM-model. We show that this model is equivalent to the ...receptor-desensitization model with three kinetic states. For the TM-model we derive the analytical form of a measure of paired pulse depression. We analyze the sensitivity of the synaptic depression phenomenon on model parameters and derive the relative importance of each of the parameters. The closed form of the measure of synaptic depression allows fitting the model to experimental data. The fitted parameters are used to make predictions about the asymptotic properties of the postsynaptic currents. We show that for synapses with the ratio of inactivation and recovery rates of the same order, the synaptic depression does not preclude the rate-coding of information: e.g. in the pyramid–pyramid connections of adult rat neocortex, rate-coding is possible for higher frequencies.

It is insufficient to calculate the number of jobs in the mining industry to determine the labour market effects of a coal phase-out. In this paper, we estimate the scale of mining-related and ...mining-dependent jobs in Europe’s largest hard coal mining region: Upper Silesia. In addition, we provide a precise structure and spatial distribution of mining-related companies using information from public tenders offered by five of the largest coal enterprises, coupled with financial and employment data from official administrative repositories. Our observations have shown a significant agglomeration effect in the region: companies within 20 kilometres of the nearest active hard coal mine were awarded 80% of all tender revenues. Moreover, we found that 41% of all identified jobs in mining-dependent companies in Upper Silesia were highly at risk of liquidation if there was to be a decline in coal production. Finally, we argue for labour market mitigation policies tailored to mining-dependent employees and the widespread application of administrative data in just transition planning to address the limitations of dominant top-down modelling approaches.
As a result of decarbonisation, the number of jobs in coal mining and mining-relatedindustries will drop. However, the risk of increased unemployment related to this process can be minimised. To that ...end, in order to mitigate the consequences of the transition away from coal, it is necessary to halt the inflow of new workers, to allow older employees to work until they reach retirement eligibility, and to provide support in advance for younger workers in mining and mining-relatedindustries so that they can take up jobs outside of the sector. To achieve that, we suggest three instruments: (1) relocating workers to coking coal mines, (2) retraining, and (3) support in starting up and running a business. With these instruments, it is possible to help accelerate decarbonisation while retaining a well-qualified workforce in the regional labour market
We study the labour market transition pathways driven by the coal phase-out in Poland between 1990 and 2050. First, we apply the concept of branching points to describe the transformation of coal ...mining in the context of three labour market trends: structural changes, demographically driven changes in the labour supply, and educational upgrading. We show that in the 1990s and 2000s, the labour market options of the miners who lost their jobs were poor, as the trajectories of all of these trends worsened their labour market prospects. However, as these trends have reversed since the 2010s, it is likely that in the future, the employment effects and the social consequences of the coal phase-out in Poland will be more positive than they were in the past. Second, we find substantial homogeneity in the employment structures of mining subregions and of particular mines, which suggests that regional approaches to managing the transition are possible. Third, our projection of the supply of and the demand for labour up to 2050 indicates that decarbonisation will lead to a surplus of Polish hard coal mining workers by 2030. However, the projected shortages of workers in other industrial sectors will create opportunities for worker reallocation that should be facilitated by policy measures.
