Comparative analysis of sustainable development of provinces

100%

Salamon J.

tom nr IV/3

1833--1842

Sustainable development involves integration of political, economic and social activities maintaining natural balance and durability of basic natural processes in order to ensure the possibility to fulfil the essential needs of individual communities or citizens, for both present and future generations. An attempt was made in the paper to evaluate the provinces in view of sustaining their development. A set of 71 indicators was used to describe the individual areas of sustainable development, i.e. economic, environmental and institutional-political order in a synthetic way. Linear ordering of provinces was conducted using their taxonomic distance from the model object.

The influence of indexing methods on effective functioning of the database

The article describes the different types of indexes. Their characteristic determines whether and when they can be used to improve database performance. Then studies are performed using different indices for different situations. The conclusions of the study can be serve as a guide to correct use of indexes.

Quantitative evaluation of veto power

100%

CHESSA M. , FRAGNELLI V.

nr 3-4

5-18

The decisiveness index and the loose protectionism index for a single player have been introduced, starting from the decisiveness and the loose protectionism indices for a collective decisionmaking mechanism defined by Carreras. Attention was mainly focused on the latter index, being proposed as a quantitative measure of the power of veto of each agent. According to this index, a veto player has veto power equal to one, while each other player has a fractional power according to her/his likelihood of blocking a given proposal. Such an index coincides with the expected payoff at the Bayesian equilibrium of a suitable Bayesian game, which illustrates the non-cooperative point of view of a decision-making mechanism.

Applicability of diatom indices for monitoring water quality in coastal streams in the Gulf of Gdańsk Region, northern Poland

This aim of this study was to test the applicability of diatom indices developed in Europe for monitoring coastal stream waters in northern Poland. Water, sediment, and diatom samples were taken from streams in the resort town of Sopot that discharge into the Gulf of Gdańsk. The physical and chemical measurements taken during the sampling period indicated that the purity of the stream waters had improved, and recently they were classified as I class water purity. This is contrasted by the studied waters’ diatom communities, which were dominated by eutraphentic taxa. High abundances of ß-mesosaprobic and α-mesosaprobic taxa were recorded at most of the sites. Diatom indices developed for water quality surveillance were calculated with the Omnidia 3 database software. Redundancy analyses (RDA), an ordination technique, was used to determine the indices that best correspond to water pollution in coastal streams.

Przeprowadzona analiza statystyczna pozwoliła określić wpływ wielkości gospodarstw na poziom uzbrojenia technicznego. Określone zostały również relacje pomiędzy poszczególnymi wskaźnikami charakteryzującymi park maszynowy. Analiza korelacyjno-regresyjna wykazała współzależność na podobnym poziomie w obu gminach. Wskazuje to na tendencje generalne wzajemnych powiązań analizowanych cech niezależnie od regionu i wielkości gospodarstw indywidualnych.

The performed statistical analysis allowed to determine the impact of the farmstead size on the level of technical infrastructure. Relations between particular indices characterizing machinery were also determined. The correlational and regressive analysis demonstrated correlations on a similar level in both communes. This indicates general tendencies of correlations of the analyzed qualities regardless of the region and size of individual farmsteads.

Zróżnicowanie gmin pod względem kierunku gospodarowania pozwoliło określić wpływ ich ukierunkowania na poziom wyposażenia gospodarstw w park maszynowy. Badania przeprowadzone zostały w formie wywiadu kierowanego i objęły swym zakresem po jednej gminie z województwa małopolskiego i wielkopolskiego. Zgodnie z oczekiwaniami obiekty z terenu typowo rolniczego tj. gminy Nowe Miasto nad Wartą, charakteryzowało lepsze nasycenie środkami technicznymi w porównaniu z gmina przemysłową Chrzanów.

Diversity of communes in terms of course of farming allowed determination of the impact of their orientation on the level of outfitting farmsteads with a machinery. The studies were performed in a form of directed interview and covered one commune from Małopolska province and one from Wielkopolska province. As expected the facilities in the typical agricultural area i.e. in the commune of Nowe Miasto on the Warta river, were characterized by higher accumulation of technical means when compared to the industrial commune of Chrzanów.
