Regional Population Density

A relative uniformity of population distribution on the territory of the country is of importance from socio-economic and strategic perspectives. It is especially important in the case of Russia with its densely populated West and underpopulated East. This paper considers changes in population density in Russian regions, which occurred between 1897 and 2017. It explores whether there was convergence in population density and what factors influenced it. For this purpose, it uses the data both at county and regional levels, which are brought to common borders for comparability purposes. Further, the models of unconditional and conditional β-convergence are estimated, taking into account the spatial dependence. The paper concludes that the population density equalization took place in 1897-2017 at the county level and in 1926—1970 at the regional level. In addition, the population density increase is shown to be influenced not only by spatial effects, but also by political and geographical factors such as climate, number of GULAG camps, and the distance from the capital city.

The author's population density index ( PDI) model is extended to three-dimensional distributions. A derived formula is presented that allows for the calculation of the lower and upper bounds of density in three-dimensional space for any finite lattice.

The City

The paper analyses the symbolic features of spaces of Serhiy Zhadan’s prose. The main attention is paid to the novel “Voroshylovhrad” and the name of the city that doesn’t exist on the geographic maps anymore. Most spaces, such as a petrol station or abandoned airfield, could be defined as non-places (the term of M. Auge). For M. Auge it’s a type of space that shows the hybridity of our life. It’s basically the transit places. That is why there are no emotions connected with those non-places: no special stories, no narrative, that could create the place itself. The analysed novel by Serhiy Zhadan assures that even those places that weren’t noticed by most people and were treated by them as non-places, were really precious for others because of their personal memories and their past time, spent there. The paper also analyses the special features of the novel according M. Auge’s term the “anthropologic place”. It’s a place that represents an identity of native group that used to live there and shows the power of a connection between the place and its inhabitants. It’s also a place, where they can feel themselves and make their own rules. Those things make places like the petrol station, worth to be defended from intrusions.

Community Based Design

This study confirms that lack of space due to high population density restricts household members and the barangay to comply with the existing law regarding composting. With these, community involvement in the design stage of compost bin as initial stage was done accordingly. The participants were voluntarily interviewed and were given questionnaires, which was endorsed and approved by barangay committee.
