    Opis:
    Od kilku lat różne ugrupowania polityczne zgłaszają postulat ograniczenia licz-by kadencji władzy wykonawczej w samorządzie lokalnym. Za każdym razem wywołuje on ogólnopolską dyskusję, w której aktywny udział biorą przedstawi-ciele partii politycznych, aktualnie urzędujący wójtowie, burmistrzowie i pre-zydenci miast oraz opinia publiczna. Celem artykułu jest prezentacja argumen-tów zwolenników i przeciwników tego rozwiązania ze szczególnym uwzględ-nieniem badań własnych przeprowadzonych w małym mieście w Polsce.
    Various political parties postulate term limits of executive power in local government for several years. Every time it raises nationwide discussion, involving representatives of political parties, mayors and public opinion. The aim of this paper is to present points of view of both supporters and opponents of this solution with a particular emphasis on personal qualitative research in a small town in Poland.

    Opis:
    The article analyzes the possibility of adopting trend estimation model to predict the average selling price of timber (CGUS). The study used information about the average selling prices of timber in chosen periods (2006-2017). The data concerning the actual CGUS was used to create a trend estimation model. The models and CGUS predictions were conducted based on three different time series encompassing 5-year periods. The predicted (CGUS) trend estimation in particular years was requested based on extrapolation, which exceeded the accepted set of information used in the study to create a trend estimation model. On the basis of the conducted study it was ascertained that the method of modeling linear trend estimation should be adopted in the price prediction process. The error assessment with which the linear function formulas are burdened, it was noticed that the value of the coefficient of residual variation was between 4.40% and 7.82%. It was also noticed that the linear modeling of CGUS trend estimation, despite unfavorable values of coefficient of determination and convergence, to some extent, can be viewed as an assistance tool in the decisionmaking process in the scope of predicting the height of the analyzed price. This view was supported by the achieved predictions which were verified with the actual prices of timber. The price difference between the actual and the predicted one was between -1.59 PLN to 2.27 PLN, and in relative terms the predictive error was between 0.83 to 1.15%. In our opinion the presented research process can constitute a reference point as a comparative element to verify the results for other, new price prediction models. The process of modeling timber prices should be extended by other predicators which are connected with forest market chain.

    Opis:
    An analysis was made of two prediction methods: the Linear Approximation Method (LAM) and Brown’s Exponential Smoothing Model (BESM). These two methods were investigated and compared in terms of their efficiency in timber price prediction. Models and price predictions were prepared based on three time series (5-, 7- and 9-year) for three years: 2015, 2016 and 2017. The analyses were conducted using data on mean annual timber prices from the period 2006-2017. This meant that the time series included the years of the 2007-2008 economic crisis. Prediction efficiency was evaluated by comparing the results obtained with actual timber prices in the years 2015-2017. It was found that the predictions generated by LAM were better than those produced by BESM. The smallest relative and absolute errors of prediction were obtained applying the linear function: Υt^ = 5.277t + 161.70. This function was constructed based on a 5-year time series. Absolute error amounted to 1.59 PLN (€0.35). Relative error was below 1%. The results of this work suggest that further studies are desirable to investigate the applicability of trend analysis to the prediction of timber prices with the inclusion of analyses of nonlinear trends. The present results of timber price modelling may provide a basis to search for a homogeneous model of timber price prediction adapted to specific conditions of timber sales.

    Opis:
    The pulmonary vein isolation remains the major target of atrial fibrillation ablation. The cryoablation lesions in the left atrium are supposed to disconnect the pulmonary vein from the atrium on the atrial side of the orifices. We hypothesized that the cryoballoon pulmonary vein isolation could result in the prolongation of the P wave duration. The aim of the study was to assess the duration of the P wave in 12-lead electrocardiogram and the influence of pulmonary vein isolation on this parameter. The study group included 21 patients (11 women and 10 men) 66.2+/-7.4 years of age undergoing cryoballoon ablation. In order to measure the P wave duration, we used the constant acquisition of electrogram and the electrocardiographic channels provided by LABSYSTEM™ Pro EP Recording System (Boston Scientific), magnifying the leads 64x. We calculated the duration in the simultaneously recorded 12-lead ECG, from the beginning of the earliest recorded P wave deflection, until the end of the latest P-wave deflection recorded in any lead. The P wave duration in the entire study group was 141.7+/-12.5 ms before the ablation and increased significantly to 151.1+/-11.5 ms (p<0.05) after the procedure. The respective values in women were 144.1+/-4.3 vs. 156.0+/-4.7 ms (p<0.01) and 139.1+/-4.6 vs. 145.6+/-4.5 ms in men (p<0.05). The mean standard deviation of every single measurement considered separately was 4.4+/-2.1 ms before the cryoablation and 4.6+/-1.8 ms after the procedure (p= not significant (n.s).), indicating very good reproducibility of the measurements. We concluded, that cryoballoon pulmonary vein isolation leads to the prolongation of the measured P wave duration. It seemed to result from conduction disturbances created by cryoablation. The clinical significance of the observed changes remains unknown.
