Koncepcja metropolitalnego slow-przedmieścia jako narzędzie poprawy jakości życia w międzymieście
PublikacjaPowstałe wskutek suburbanizacji struktury uznawane są za nową formę krajobrazu zurbanizowanego. Poprawa ich jakości wymaga stworzenia nowych narzędzi planowania międzymiasta (niem. die Zwischenstadt). Należą do nich innowacyjne wizje przestrzenne, kreujące alternatywę dla globalnych trendów homogenizujących kulturę życia społecznego w strefi e podmiejskiej. Inspirowana modelem agri-hood autorska koncepcja slow-przedmieścia wykorzystuje doświadczenie...

Whither the need and motivation for open government data (OGD) promotional strategies?
PublikacjaPurpose It has been underscored in the extant literature that open government data (OGD) has not percolated across the length and breadth of any country, let alone the awareness of the OGD among the stakeholders themselves. In this vein, this study aims to underline the reasons as to why OGD promotion merits consideration apart from underlining the manner in which OGD promotion may be done. Design/methodology/approach Based on...

Does one currency mean one price?
PublikacjaEuropean Monetary Union was expected to have many consequences for the economies of participant countries. Theory suggested that through a higher volume of trade and stronger competition in the Eurozone, a single currency would lead to a reduction in price dispersion. As far as prices are concerned, two effects were expected: an immediate effect due to the technical characteristics of the changeover process, and a long-term one...

Periodic Solutions of Generalized Lagrangian Systems with Small Perturbations
PublikacjaIn this paper we study the generalized Lagrangian system with a small perturbation. We assume the main term in the system to have a maximum, but do not suppose any condition for perturbation term. Then we prove the existence of a periodic solution via Ekeland’s principle. Moreover, we prove a convergence theorem for periodic solutions of perturbed systems.

Quadratic stochastic operators on Banach lattices
PublikacjaWe study the convergence of iterates of quadratic stochastic operators that are mean monotonic. They are defined on the convex set of probability measures concentrated on a weakly compact order interval S = [0, f] of a fixed Banach lattice F. We study their regularity and identify the limits of trajectories either as the “infimum” or “supremum” of the support of initial distributions.
