The article deals with the issue of the meaning of the Polish early education coursebooks for conservation/change in educational practices. It is the liberal and constructivist discourse to which the coursebook authors should refer (especially in the context of the present time and democracy) if these books are to become a tool of the prodevelopmental and emancipatory interest of both students and society. However, the research on Polish coursebooks for early education (grades I – III), show that this very condition has not been ful3 lled. In such a situation it is the German school coursebooks that might be inspiring because of their discursive background as well as of the methodological proposals and the range of content present in them. The article is also an attempt to reconstruct “the image of school” present in German early education coursebooks. It is possible to name and describe the key dimensions in this image such as: the democratic nature of teacher-student relations, the focus on the activation of students’ personal knowledge as well as on their ethical and cognitive autonomy, realistic vision of the world, trust in students’ competences, and creating the sphere of the nearest development.
Annoyance ratings for artificially created noises, resembling the main characteristics of temporal wind turbine noise, were studied by means of a listening experiment involving 21 participants with normal hearing. Three types of stimuli were examined: broadband noise (−4 dB/octave), noise generated by moving cars, and narrowband noise. All stimuli had the sound level fluctuations typical for wind turbine noise. The magnitude of the sound level fluctuations was measured in a quantitative way, by using the characteristics of amplitude modulated sound: modulation rate and modulation depth. Our aim was to examine how the modulation rate and the modulation depth influence the noise annoyance assessment of broadband and narrowband amplitude modulated noises. Three different modulation rates, 1, 2 and 4 Hz, and sound level fluctuations (a measure of the modulation depth), 3, 6, 9 dB, were applied to each type of stimuli (with exception of noise generated by the moving cars) and investigated. The participants in the listening experiment were presented with sound stimuli in laboratory conditions and asked to rate their annoyance on a numerical scale. The results have shown a significant difference between the investigated conditions. The effect was particularly strong between the annoyance judgments of different types of noise (narrow and broadband), and modulated versus unmodulated noises. Temporal fluctuations occurring in wind turbine noise are very pertinent to the perception of annoyance and could be responsible for its being a relatively annoying noise source. The obtained results were discussed and compared to the typical modulation rates and level changes that occur in recordings of real wind turbine noise.
Nowadays, the ubiquity of changes determines a new approach to programming development. In this situation, it is necessary to update the strategy of socio-economic development in many cities. The aim of the paper is to present the process of updating the city’s development strategy on selected examples (Katowice, Cracow, Poznań, Warsaw and Wrocław), through the prism of the scale and tools of public participation. Wrocław is a centre that particularly approached the implementation of the megatrend of public participation in the work on updating the development strategy. The paper delineates differences between public consultations and real public participation. The following research methods were used in the study: literature research, analysis of source texts, benchmarking and comparative analysis. The time horizon covers the period of public participation in the documents’ construction and is different for particular cities selected for analysis, however, it falls in the years 2013-2017.
