The author reviews the actual state of research on the Langyel culture in Upper Silesia focusing mainly on taxonomic issues. He rejects terms 'the Jordanów group' and 'the Ocice group' as proposed in the literature, links of Upper Silesian Lengyel material with the Moravian Painted Pottery culture, and - most of all - connecting the earliest finds of that type with the Stroked Band Pottery culture and the Malice culture (group). Instead, he puts forward a hypothesis that the Lengyel type pottery of Phases I through IV constitute a certain unity termed by him as 'the Upper Silesian Lengyel group' (hornoslezská lengyelská skupina). The author underlines the fact that the analyzed phenomenon reflects the local development of the Lengyel culture in Upper Silesia (in the upper Basin of the Odra River).

The contradiction between the theoretically unlimited access to information and the efficiency of information searching has been pressing researchers and IT professionals to enhance the collaboration of computers and human workforce in the processes of information and knowledge acquisition. The importance attached to information retrieval methods has expanded beyond the library environment, resulting in the increasing respect of the professional background of traditional information retrieval languages and in the utilization of their theoretical principles even by business organisations. Having set the objective of the quick and comprehensive searching of portal and webpage contents, the professionals engaged in the development of the so-called semantic or intelligent web are working towards the creation of a web-based open and distributed system, that aims to apply standard descriptive languages to the online information sources, and will reach its full potential when the automatic distribution of data becomes possible. New programs and methods are being developed with the collaboration of software engineers, and the milestones of the progress are reported on by W3C working groups. The coordinated and computer-based development of various traditional and automatic cataloguing languages demonstrates remarkable achievements, however, automatic solutions are only provided by a few softwares. As far as computer-based classification tools are concerned, a group of experts in the theoretical issues of information sciences regard taxonomies and related tools as an easily adoptable classification system (a controlled vocabulary with a low level of hierarchy) that can be generated relatively quickly. Thus this paper primarily concentrates on taxonomy.

The purpose of this paper is to present practical applications of multidimensional comparative analysis to assess the competitive position of domestic banks listed on the Warsaw Stock Exchange with the use of financial and non-financial value drivers. The research included a group of 10 domestic banks and 2007-2011 period. As a result of research author creates ranking of banks.

The work includes a description of the period from the moment of setting up Polish Polar Station on King George Island (1977) to the end of International Polar Year IV in 2009. Researches on flower plants focused, among others, on plants' morphology, morphological composition of the pollen and anatomical ultra-structure of the leaves. There were also carried out biochemical and other searches for the internal mutability. Within physiological studies one concentrated on the problem of reaction to temperature stress. Biological researches focused mainly on solving taxonomic and bio-geographic problems. Finally, were published several monographs and, among others, the first in history complete description of moss' flora of the whole of Antarctic (2008). Research works over algae included also such issues as floristics, bio-geography, taxonomy and ecology (for instance, the rookery's impact on distribution of algae, or the influence of inanimate factors on dynamics of condensing the Diatoma in different water and soil-bound tanks). Up till now, within mycological investigations has been identified a variety of lichen fungi that for the most part of Antarctic are a novelty. There were scientifically described new for science genera and species of Western Antarctic. Lichenological studies were made in the field of taxonomy, geography, lichenometry, biochemistry of lichens, lichenoindication, ecophysiology and from the point of analysis of base metals' content. There were also described new for science species. Since 1991, were published the results of searches for the base metals' content and vestigial chemical elements in lichens' thallus. Ecophysiological researches concerned both micro-climatic conditions' impact on primary production and lichens' adaptation to a very cold climate. One discovered a mechanism of two-phase hydratization/dehydratization of lichens' thallus. On the ground of palaeobotanical analyzes was reconstructed a development of flora in Western Antarctic from the late Cretaceous period to the beginning of Melville's continental glaciation. One singled out three floristic stages and were reconstructed their peculiarities in the development of flora. There was also described an early Jurassic flora of Hope Bay (Pólwysep Antarktyczny - Antarctic Peninsula) that turned out to be the richest Jurassic flora in the world. From that point of view were analyzed new species of mineral plants. Ecological researches concentrated on the problems connected with several issues and, among others, with the processes of settlement and succession, distribution and ecology of land biotopes, changes in their spatial structure, and state of biotopes' biological mass. The second group of issues concerned the anthropogenous impacts. One also analyzed early stages of synanthropization of flora. Another important issue was recognizing an extent of the pollution of the environment, particularly with base metals. In the years 1977 - 2009 were published, at least, 426 notes, articles and monographs that were a result of botanical and mycological researches on sheets of land of Antarctic and Sub-Antarctic.
