Opis:
Morphometric attributes of 705 stromatoporoid specimens from a number of exposures from the Silurian of Podolia (Ukraine) and the Devonian of the Holy Cross Mountains (Poland), representing a wide array of shallow water carbonate sedimentary environments, have been analysed. Taken into account were such parameters as: general shape of the skeleton, shape of the final growth form (living surface profile), upper surface character, latilaminae arrangement, burial ratio and type of initial surface. A number of new ratios has been introduced, designed mainly to improve the mapping of the outlines of the stromatoporoids upper surfaces. All studied specimens were treated as belonging to one group, and relations between particular attributes were tested. The results were analysed in terms of potential environmental factors influencing stromatoporoid morphometric features. Most of the distinguished attributes are common in the studied group and occur in various combinations, with an important exception of parameters designed to reflect the shape of the skeleton’s upper surface, which are distinctly predominated by convex variants. This indicates that surface concavity was a highly undesired feature among stromatoporoids. Upper surface convexity is interpreted herein as a response to the hazard of clogging of the animals pores by tiny sediment particles suspended in the bottom turbid water layer. Common low burial ratios of final living surface profiles and the occurrence of specimens with a smooth upper surface but a non-enveloping latilaminae arrangement are other reflections of this phenomenon. Burial by sediments and redeposition were also important factors governing stromatoporoid development. No direct arguments indicating photosensitivity of stromatoporoids can be deduced from the presented results. The hitherto postulated allometric tendency among stromatoporoids of starting growth as laminar forms and later adopting consecutively higher profile shapes has not been confirmed here. On the contrary, a tendency for gradual elimination of very high profile forms with increasing stromatoporoid size has been observed. The final shape of a stromatoporoid skeleton was always an effect of a combination of various agents.

Opis:
The High-Tatric succession of the Tatra Mountains represents the Tatricum domain of the Central Western Carpathians, which in the Jurassic was located on the southern margin of the incipient and expanding Vahic Ocean – a branch of Western Tethys. This paper describes the various depositional consequences of extensional tectonic activity as it impacted on sedimentation in the High-Tatric succession of the Tatra Mountains during the Early and Middle Jurassic. Evidence of such impacts on depositional style and facies development are present within the Dudziniec, Smolegowa and Krupianka formations, in all the High-Tatric tectonic units. These impacts also include erosional surfaces and sedimentary gaps separating particular formations, commonly associated with minor angular unconformities. The Lower Jurassic, pre-Bajocian, Dudziniec Formation of the Kominy Tylkowe (autochthonous) Unit is developed in mixed carbonate-clastic facies. The occurrence and proportion of sand-dominated and carbonate-dominated facies, as well as their thickness differences, were controlled by syndepositional tilt-block tectonics, taking place both in depositional and in neighbouring source areas. The Smolegowa and Krupianka formations (Bajocian–Bathonian) occur in all High-Tatric tectonic units, but in the Czerwone Wierchy and Giewont units they are represented mainly by laterally discontinuous bodies of crinoidal limestone of very limited thickness. The preservation of these deposits only in some areas, as well as their thickness reductions, are effects of differentiated subsidence and uplift of isolated blocks taking place in an extensional regime. Moreover, the Krupianka Formation abounds in condensed facies with ferruginous crusts and stromatolites – a feature characteristic of rapidly drowning ocean margins. Deposits of the Dudziniec, Smolegowa and Krupianka formations are also preserved as infills of extensive systems of neptunian dykes penetrating mainly the Triassic substrate, which is yet another classic symptom of synsedimentary extension. The dominant influence of tectonics on sedimentary development ceased with the onset of deposition of the Raptawicka Turnia Formation in the Callovian.

Opis:
Artykuł ukazuje podstawowe założenia pedagogii jednego z wybitnych polskich pedagogów przełomu XIX i XX wieku – ks. Bronisława Markiewicza, którego myśl pedagogiczna również dzisiaj nie przestaje fascynować wielu pedagogów, czyniąc z nich mistrzów w dziedzinie wychowania. Tekst wskazuje na oryginalność założeń wychowawczych ks. Markiewicza, która wyraża się w iście nowatorskim sposobie wykorzystania tradycyjnych wartości jakimi są powściągliwość i praca. Autor zwraca również uwagę na potencjalną możliwość wykorzystania pedagogii ks. Markiewicza we współczesnej pracy pedagogicznej, gdyż stanowi ona niezwykle cenne „narzędzie” w procesie kształtowania u młodzieży osobowości dojrzałych i harmonijnych - dobrych chrześcijan i uczciwych obywateli.

Opis:
Streszczenie Integralne wychowanie dziecka według Edmunda Bojanowskiego wraz z nieodłączną od niego ideą ochrony dziecka jest wyrazem twórczych przemyśleń i poszukiwań tego wybitnego polskiego społecznika i myśliciela XIX wieku. Jego myśl pedagogiczna nie utraciła swej aktualności i również współcześnie stanowi ważny punkt odniesienia dla praktyki pedagogicznej. Tekst wskazuje na oryginalność systemu wychowania Edmunda Bojanowskiego, który w swych podstawowych założeniach odwołuje się do natury, historii i religii i może zostać pomyślnie wykorzystany jako cenne narzędzie w procesie kształtowania u dzieci mocnych i harmonijnych osobowości. Materiał i metody Wykorzystano literaturę źródłową i opracowania dotyczące koncepcji wychowania Edmunda Bojanowskiego. Wyniki W przekonaniu E. Bojanowskiego "sukces wychowawczy" możną osiągnąć troszcząc się o integralny rozwój i wychowanie dziecka. Wnioski Bez dobrze pojęty "ochrony" dziecka integralny rozwój i wychowanie dziecka jest znacznie utrudnione.

Opis:
This contribution presents the record of an abundant assemblage of well-preserved, thallophytic noncalcified algae and of an epibiotic form that has been recognised as a putative graptolite from the upper Silurian (Ludlow, Gorstian–Ludfordian) of Podolia (western part of Ukraine). The sediments represent a shallow peritidal zone of the shelf. A new genus and species, Voronocladus dryganti, belonging to the Dasycladales Pascher, 1931, is established. Most of the specimens representing the algal thallus are overgrown by problematical epibiotic graptolites, described as Podoliagraptus algaeoides gen. et sp. nov. This phenomenon is explained as an epiphytic mode of life of the putative graptolite on algae, and is herein compared to recently known coexistences of algae with other organisms. The excellent state of preservation, and the abundance of studied Dasycladales algae and epibiotic problematics indicate that the investigated mudstone layer can be treated as a ‘Konservat Lagerstätte’ sensu Seilacher (1970).
