“…Of course, the determined criterion does not absolutely guarantee the actual statistical or meteorological independence of the sample members. Some suggestions of how to deal with correlated observations can be found, for example, in Holešovský et al (2014). In this paper, samples with aggregation levels of 5,10,15,20,30,45,60,90,120,180,240 and 360 min were generated.…”

Precipitation records from six stations of the Czech Hydrometeorological Institute were subject to statistical analysis with the objectives of updating the intensity-duration-frequency (IDF) curves, by applying extreme value distributions, and comparing the updated curves against those produced by an empirical procedure in 1958. Another objective was to investigate differences between both sets of curves, which could be explained by such factors as different measuring instruments, measuring stations altitudes and data analysis methods. It has been shown that the differences between the two sets of IDF curves are significantly influenced by the chosen method of data analysis.

“…Detection of outliers is a problem that is constantly discussed in technical literature, and many methods have been proposed for its solution. Methods and algorithms for detection of outlier measurements in environmental data can be found in [24,25]. Methods for detecting outliers in spatial environmental data were proposed in [26,27].…”

Sustainable development is perhaps the most important idea of our present time. This concept anticipates major civilizational change on the ecological, social and economic level [1]. Despite the imposition of European Union limit values for particulate matter (PM), frequent exceedances of the limit for PM 10 concentrations have been observed widely across Western Europe, particularly in Switzerland, Belgium, Germany, Italy, Norway and the Czech Republic [2]. Poland also suffers from particulate pollution, for example PM 10 particulate matter concentration is a substantial and as yet unresolved problem in the area of Warsaw, and other big cities [3, 4]. Airborne particulates are significant conveyors of metals, some of which are toxic and typically exist naturally and excessively in the environment [5]. Recent studies on the health problems associated with exposure to PM with an aerodynamic diameter of 10 µm or less (PM 10) have identified a variety of health-related problems that include deterioration in lung function, chronic pulmonary disease, heart disease, and premature death, along with a rise in mortality [6]. Consequently, heavy metals in association with PM definitely affect the biological and physiological functioning of the human body [5].

“…However, due to environmental regulation, the situation has improved in the last ten years. It is considered a relatively safe city, with a decreasing level of crime and increasing tourist interest [79]. Brno has plenty of city parks, with the oldest dating back to the late 18th century.…”

The Oasis of Peace? Social Perception of Urban Parks from the City-Dwellers’ Perspectives

2022

View full text Add to dashboard Cite

The article focuses on the social perception of urban parks, from the perspective of city dwellers. For the analyses, eight focus groups with N = 48 participants were organized. The findings indicated urban parks as a meaningful part of the city dwellers’ place identity, who interpret them as an “oasis of peace” or “places for meeting”. The article further analyzes the conflicts emerging from the clashes of different perspectives on how urban parks should be used, what functions they should fulfil, or what characteristics they should have. The article discusses the possible implications of some of these contradictions, connected with the changing nature–culture understanding in contemporary society and the unresolved marginalization of some of the social groups.
