Zmiany strukturalne przemysłu Polski w warunkach kryzysu gospodarczego
The global economic crisis which started in 2007 in the United States of America, at different times and to a different extent affected various sectors and national economies of the world. In Poland, its symptoms were noticeable later than in other countries. In the first phase of the crisis (2007- 2008), there was no direct effect, due to the fact that initially the turmoil on global financial markets had weaker effect on the national economy, and it was limited mainly to capital markets, affecting the sectors of agriculture, industry, and services to a lesser extent. However, as recession grew in force, the crisis gradually began to affect also the results of economic activity, including industry. In 2009, a significant decrease in the value of production sold, as compared to the previous year, was observed. The question is whether this had been reflected in changes of spatial industrial structure. The five-year period of the economic recession seems to be long enough to assess such changes. Therefore, the paper analyses the transformation of the spatial structure of Polish industry during crisis, based on the basic indicators of potential, such as employment and the value of production sold, as well as concentration coefficients. The year 2007 was adopted as the base year, treating it as a pre-crisis year. The conclusions of the detailed analysis indicated that the impact of crisis on the change of the spatial structure of the Polish industry is very limited and the observed trends of change did not differ substantially from the general industrial development trends in Poland, identified by previous studies. It should be noted, however, that the structure of industry is characterized by high “inertia” due to the complexity and size of the investment process. Therefore, in the following several years no deep and sudden transformation should be expected, even during economic recession.
A local crisis as a specific part of the global one: the case of Siberia
Any global phenomenon manifests itself differently in various countries and regions. Our idea is that for Russia the global crisis can be considered as the third phase of the long-term national socio-economic crisis, and for the important part of Russia, Siberia, even as the fourth phase.These phases are:• First, the crisis of economy, of ideology, of social relationships and of political system stemming from the Soviet times, having brought the crush of the state, some problems of which have been still unsolved;• Second, the crisis of the 90s, born from this crash and economic reforms, including the very crush of the integral country, very painful for common people, poverty, together with social pessimism and passiveness of people who were robbed by the hyperinflation and stagnation of the sectors, such as science and education, that had never been backward in the Soviet times and could perhaps serve as growth points for the new economy, if used and stimulated properly.• Third, specifically Siberian, extensive out-migration and depopulation, in the conditions when state economic policy is influenced by ultra-liberalism denying any state regulation, together with power hyper-centralization, which both tendencies, paradoxically united, lead automatically to concentration of everything in wealthy Moscow.• Fourth, the very global crisis itself
AXIOMATISABILITY OF WEAKLY FLAT, FLAT, AND PROJECTIVE S-ACTS
ABSTRACT This paper gives necessary and sufficient conditions on a monoid S that the class of flat left S-acts be (first order) axiomatisable. It presents also a streamlined version of the result of Stepanova that the class of projective left S-acts is axiomatisable if and only if the strongly flat left S-acts are axiomatisable and S is left perfect.
