The article presents the research on the cooperation of kindergarten teachers with institutions / organizations. The creation of the vision of a new model of this cooperation required examining the prevailing relations at this level and learning the determinants influencing the activities undertaken by the partners. For this purpose, a research was conducted in Poland in 2016-2017. It was preceded by the pilot study carried out in 2015. The participants of the research in the pilot study were parents of preschool children and kindergarten teachers from villages and towns in the Mazowieckie Voivodeship, and representatives of institutions / organizations cooperating with the kindergartens in the Mazowieckie Voivodeship. In the relevant research, three microsystems were taken into account: parents; teachers working in kindergartens in rural areas, cities and all over Poland; and representatives of institutions / organizations cooperating with kindergarten teachers globally. The data analysis made it possible to select the strengths and weaknesses of cooperation between Polish kindergarten teachers and institutions / organizations. As a result, a based on 9 theses model of cooperation between kindergarten teachers and institutions was created, and the following paradigms were identified: cooperation requires partners' self-reflection, cooperation is based on working at oneself, cooperation creates empathy and trust, cooperation expands linguistic and cultural capital, cooperation that offers a new quality of life in partnership relations is a product of transformations taking place over time.

The construction industry is an economic sector that is characterized by seasonality. Seasonal factors affect the volume of production, which in turn affects the accident rate. The aim of the research presented in the article was to develop a model for predicting the number of people injured in occupational accidents in the construction industry. Based on the analysis of statistical data and previous studies, the occurrence of certain regularities of the accidentality phenomenon was found, namely the long-term trend over many years, as well as seasonality and cyclicality over the course of a year. The found regularities were the basis for the assumptions that were made for the construction of the model. A mathematical model was built in the non-linear regression dimension. The model was validated by comparing the results of prediction errors generated by the developed model with the results of prediction errors generated by other known models, such as ARIMA, SARIMA, linear and polynomial models, which take into account the seasonality of the phenomenon. The constructed model enables the number of people injured in accidents in the construction industry in selected months of future years to be predicted with high accuracy. The obtained results can be the basis for making appropriate decisions regarding preventive and prophylactic measures in the construction industry. Commonly known mathematical tools available in the STATISTICA package were used to solve the given task.

“…In order to determine the similarities between the relationships between the selected morphometric features of the reservoirs, the average temperature of the water retained in them for the duration of ice phenomena occurrence (at a depth of 50 cm), the average thickness of the snow cover deposited on the ice (independent variables) and the average and maximum thickness of the ice (dependent variables) during the three winter seasons, the analysis of the discrimination function, principal components analysis (PCA) and the canonical analysis (RDA) were applied (Jolliffe, 1986;Krzanowski, 2000;Zuur et al, 2007;Topolski and Topolska, 2019;Topolski, 2019Topolski, , 2020a. Redundancy analysis (RDA) is the canonical form of principal component analysis (PCA) and is a method for reducing the dimensionality of multivariate data by introducing a Origin (G, dyke-type; N, subsidence bowl; P g , polygenetic; P e , former extraction pit; S, artificial bowl; Z, dammed-lake).…”

“…To demonstrate the relationship between the groups of independent and dependent variables in the water bodies studied, principal component analysis (PCA) was used. An analysis combining PCA with RDA was applied to determine the detailed directions of the largest differences between the reservoirs and the measured parameters (Topolski, 2019). First, it was checked which dependent and independent variables are most strongly distinguished (discriminated) using discriminant function analysis.…”

The paper discusses the reasons behind the variation in the thickness of ice on 39 anthropogenic water bodies located in the Silesian Upland (southern Poland). The studies were conducted over the course of three consecutive winter seasons. The measurements and observations were scheduled every 2 days during the freezing and ablation of the ice, and every 4 days when ice cover was present. Each time the thickness of the ice cover and the snow layer covering it were measured. The results show that the 35 water bodies studied are characterized by a similar—quasi-natural—ice regime, in which ice thickness variation depends mostly on the air temperature and the thickness of the snow layer covering the ice. The ice thickness on those water bodies does not significantly differ from that observed on lakes located in northern Poland, measuring on average from circa 4 to 21 cm, and with maximum thicknesses ranging from circa 14 to 40 cm, depending on the season. Four water bodies are characterized by different ice conditions; in their case the average and maximum ice thickness was significantly lower. In the Niezdara N water body this was caused by the inflow of warmer potamic water (quasi-natural regime), whereas in Pod Borem, Sośnicka, and Somerek it was caused by discharges of warm mine water (anthropogenic regime).
