Opis:
Recurvoides infernus sp. nov., one of the oldest representatives of the superfamily Recurvoidacea (Foraminifera), is described from a thin black claystone overlying the manganese deposits of the Krížna Unit in the Western Tatra Mountains (Poland). These manganese carbonates/silicates were laid down around a shallow−water exhalative submarine hydrothermal vent that was active in the early Toarcian. The microfossils are possibly the first described Jurassic foraminifera associated with hydrothermal vents. The assemblage is characterized by a high abundance and dominance of this new species. The primary lamination of the black claystone, the lack of any macrofauna, and an elevated TOC content point to oxygen−deficient conditions during sedimentation of these deposits. Furthermore, the nearly exclusive occurrence of agglutinated foraminifers suggests a low pH level. It is likely that the foraminifers colonized vent−related bacterial mats which acted as a rich and stable food source. Modern shallowand deep−water hydrothermal vents may represent similar habitats.

Opis:
This article looks at the contemporary rebuilding of the sphere of influence of the Russian Federation, which covers the area of the so-called “near abroad”. The choice of the tactics results from the possible influence of the Russian state in this area. Thus, in addition to using the techniques of the so-called soft power, the catalogue includes primarily those activities that enable Russian decision-makers to manage conflict. The process of ‘claiming Russian land back’, initiated since the collapse of the bipolar system, should be interpreted as a political imperative to return to imperial politics. The instruments for their implementation were both traditionally understood leadership in the world, when the fate of all states and nations was decided by the greatest powers, to which Russia belonged from the first half of the nineteenth century. Another very effective tool for restoring the status quo ante of the ‘Russian empire’ turned out to be the ancient Roman strategy of divide et impera, an approach that has made it possible, from the very beginning, for the Russian Federation to strive to restore its hegemonic position in the territory of the countries that once formed the Soviet Union with it. The inability to impose sovereignty by such a soft influence or to inspire and extinguish potential conflicts has led to the armed assertion of its rights by Russia. Consequently, the policy adopted by Russian decision-makers may not only cause an armed conflict on a large European scale, but also other artificially induced cataclysms, difficult to predict, the consequences of which will have to be handled by the future generations.

Within recent years the percentage of students in relation to the total population of young adults has been increasing in Poland. In search of the psychological consequences of this situation a study has been conducted on the relation between the level of activity of students and both the objective and subjective indicators of their effectiveness and the level of autotelism/calculation of the initiated activities. The study in question has been performed among a group of 473 students of the University of Silesia, and the results thereof indicate differences between the non-active, averagely active and above-averagely active students in the scope of grade point averages, the amount of granted scholarships, subjectively perceived attractiveness for colleagues as well as for the potential employer, the level of identity integration and the position in group hierarchy. The theoretical concept for analyses is constituted by the concept of emerging adulthood, the evolutionary approach and the concept of career capital.

Opis:
Bositra limestones of Aalenian–Lower Bathonian age crop out in the Krížna unit in the Western Tatra Mountains (Poland). They are sandwiched between pelagic red limestones and radiolarites and display lateral facies variation. Four facies were distinguished: (i) Bositra packstones/grainstones, (ii) crinoidal packstones/ grainstones, (iii) Bositra-crinoidal packstones, and (iv) Bositra-radiolarian wackestones. The Bositra packstones/ grainstones were laid down in high-energy setting, while Bositra-radiolarian wackestones in calm condition. Crinoidal packstones/grainstones represent density current deposits. Bositra-crinoidal packstones resulted from intense bioturbation and mixing of crinoidal packstones/grainstones with background Bositra-rich deposits. Topographic gradient affected the lateral facies variation. Taphonomic factors strongly controlled by energy of the sedimentary environment, ecological factors which caused domination of Bositra bivalves in benthos assemblage and dissolution eliminating non-calcitic bioclasts could resulted in formation of the Bositra limestones. The eutrophication of water column and remodelling of the Krížna Basin, which finally led to deposition of radiolarites seem to be of considerable importance. Hence, Bositra limestones can be regarded as the record of the interme- diate stage of the basin evolution towards radiolarite formation.
Wapienie bositrowe wczesnego aalenu–wczesnego batonu, które odsłaniają się w jednostce kriżniańskiej w Polskich Tatrach Zachodnich znajdują się w profilach pomiędzy pelagicznymi czerwonymi wapieniami a radiolarytami (Fig. 1, 2; Lefeld et al., 1985; Gradziński et al., 2004). Wapienie te wykazują wyraźne facjalne zróżnicowanie. Wydzielone zostały następujące facje: (i) bositrowe pakstony/greinstony, (ii) krynoidowe pakstony/greinstony, (iii) bositrowo-krynoidowe pakstony i (iv) bositrowo-ra diolariowe wakstony (Fig. 2, 3). Bositrowe pakstony/greinstony powstały w środowisku o stosunkowo wysokiej energii, a bositrowo- radiolariowe wakstony w warunkach niskiej energii. Krynoidowe pakstony/greinstony są interpretowane jako osady prądów gęstościowych, a bositrowo-krynoidowe pakstony jako osady prądów gęstościowych zbioturbowane i zmiksowane z osadami tła depozycyjnego. Zróżnicowana morfologia basenu wpłynęła na oboczną zmienność facjalną omawianych wapieni i przestrzenny rozkład facji (Fig. 4). Powstanie wapieni bositrowych było warunkowane przez czynniki natury tafonomicznej, związane z energią środowiska sedymentacji, natury ekologicznej decydujące o dominacji bositr w zespole bentosu i procesy rozpuszczania eliminujące nie kalcytowe bioklasty. Postępująca eutrofizacja wód (Bartolini & Cecca, 1999; Cobianchi & Picotti, 2001) i przemodelowanie basenu kriżniańskiego związane z procesami ryftingu Zachodniej Tetydy, które ostatecznie doprowadziły do depozycji radiolarytów, wydają się mieć zasadniczy wpływ na powstanie wapieni bositrowych. Tak więc, wapienie bositrowe reprezentują przejściową fację poprzedzającą w czasie powstanie tetydzkich jurajskich radiolarytów.

Opis:
Sparry limestone, ferruginous muddy limestone and limestone breccia have been found in the Western Tatra Mts. They occur within Jurassic rocks of the Choč Nappe just below red conglomerates of probable Eocene age. The deposits found bear strong resemblance to the infill of subterranean karst forms. They differ significantly from Quaternary karst deposits of the Tatra Mts. The δ18O values of spelean carbonates suggest crystallisation at relatively high temperatures (over 20°C) whereas their relatively negative δ13C values imply the presence of soil-derived CO2 linked with vegetation dominated by C3 pathway plants. The karst forms and their infill were formed before the Eocene transgression, which shows unequivocally that the Tatra Mts. were subjected to karstification at that time.

Opis:
An assemblage of 120 mammal remains of Pleistocene age has been collected from the fluvial deposits of river Raba at a gravel pit in the village of Targowisko, 30 km east of Kraków, southern Poland. Nearly 100 remains represent woolly mammoth Mammuthus primigenius. Other remains belong to four or five such mammal species as horse Equus ferus, woolly rhinoceros Coelodonta antiquitatis, red deer Cervus elaphus and steppe bison Bison priscus or aurochs Bos primigenius. Pleistocene coarse-grained deposits containing isolated bones, teeth and tusks occur in the lowermost part of the fluvial succession in the open pit, presently inundated by groundwater. The surfaces of the majority of bones and teeth show abrasion damages by fluvial transport, including their rounding and smoothing as well as scratches and grooves. Traces of carnivore activity are visible on mammoth and horse bones. The location, dimension and shape of these marks suggest wolf or cave hyena gnawing.

Opis:
The article presents an attempt to confirm the circumplex structure of goal contents, identified in 15 cultures around the world (Grouzet et al., 2005), in nine Polish samples. The procedure followed steps from the original study and included testing the assumed 11-factor goal structure and the two-dimensional circular organization of the goal contents. None of the analyses showed outcomes that would explicitly confirm the results attained in the original study. The CFA showed rather poor fits. Results of the MDS generally supported the assumption about the two-dimensional goal contents structure, however ipsative distance analysis reproduced only one of the two assumed dimensions. Finally, although the CIRCUM analysis showed in principle that in the Polish sample the organization of goal contents on the circumference was quite similar to original, the RMSEA indicated poor fit. Methodological and conceptual reasons for the replication failure are analyzed and discussed.

Opis:
The work included an analysis of the primary real estate market in Krakow in 2017‑2020. The above analysis was carried out on the basis of transactions obtained from the official register at the city hall. The results of the research made it possible to observe the changes taking place in the market: the prices grew moderately, and the number of transactions was between 8,000 and 11,000 each year. In 2020, due to the COVID-19 pandemic, the number of transactions conducted dropped sharply. Despite the reduced interest of potential buyers, prices per square meter of residential space increased significantly during the period under review. Thus, the pandemic only affected the number of transactions and not the average price per unit of space.

Opis:
Lower-Middle Jurassic glaucony-bearing deposits crop out in the Polish part of the Križna Unit in the Western Tatra Mts. These deposits, up to 20 cm thick, consist of glaucony-rich marls and limestones. The glaucony grains constitute up to 30% volume of the deposits. They represent an evolved stage of glauconitization since they contain more than 7% K2O. The content of Al2O3 is high (up to 19.97%, average 16.98%) while the content of Fe2O3 is low (not more than 23.48%, average 12.84%). These features are interpreted as a product of diagenetic processes. The glaucony-bearing deposits were formed at an upper bathyal depth and their rate of deposition was very low, what allowed long-lasting evolution of the glaucony grains. The K-Ar age of the glaucony grains is much younger than the biostratigraphic age of the studied section. The lowering of the K-Ar dates is interpreted as a result of loss of radiogenic Ar from the lattice of the glaucony.

Opis:
The Lower Jurassic Adnet type red limestones and marlstones (Kliny Limestone Member, Huciska Limestone Formation) of the Krížna unit in the Tatra Mountains comprise cephalopod fauna represented by ammonites, belemnites and rarely by nautiloids. Ammonites belong to the families Phyloceratidae, Lytoceratidae, Hildoceratidae and Dactylioceratidae and indicate Early Toarcian Serpentinum Zone, Middle Toarcian Bifrons Zone (most probably Sublevisoni and Bifrons Subzones) and Late Toarcian Pseudoradiosa Zone. Hence, the age of Adnet type deposits may be estimated as Early Toarcian-Late Toarcian. Relatively moderate diversity of ammonite assemblage is noticed. Ammonites and nautiloids are preserved mainly as internal moulds, only some specimens display preserved calcified shells. Part of this macrofauna has resedimented character. Studied ammonite assemblage is closely related to that of the Mediterranean Province.

Introduction and objectives. Surgical treatment due to brest cancer have an impact on women sexuality. There is a need for research about effective indications for sexology consultation in women after such treatment. The aim of this study is to determine the indications for sexology consultation in women after surgical treatment for breast cancer. Materials and method. We tested 42 women patients diagnosed with breast cancer who had undergone mastectomy 3 months before the study. 3 months after the surgery the women were surveyed using the Polish version of FSFI assessing sexual functioning in women. The result of PL-FSFI were compared with the control group. Results. It was found that the mean score of PL-FSFI in the study group 3 months after the surgery was 13.33 points (score range: 1.2–31.7; median 8.3 points) with a statistically significant difference in terms of areas: desire, arousal, lubrication and orgasm in favour of the control group. The total score of PL-FSFI was significantly lower in women after mastectomy than in women after breast-conserving surgery. It has been shown that sexually active women in whom the surgery concerned the right breast (on the side of the dominant hand) scored lower on the scale “sexual functioning” of QLQ-BR-23 than women with surgery of the left breast, with this difference being statistically significant. There was a statistically significant correlation between the baseline performance status on the Zubrod scale and the scales: desire, lubrication and satisfaction of PL-FSFI. Living in a small town proved to be statistically significant for predicting a lower risk of sexual dysfunction among the surveyed women. Conclusions. The women who underwent surgery due to breast cancer had a higher risk of sexual dysfunction compared to the general population. Higher risk of sexual dysfunction especially concerns women after mastectomy, those who underwent breast surgery on the side of the dominant hand, and those with a worse preoperative overall level of functioning of ≥ 1 point on the Zubrod scale. A lower risk of disorders was observed in women living in smaller towns. The above factors indicate the advisability for sexology consultation in women with breast cancer.

New locality of slope breccias was found in the Western Tatra Mts. It occures in the Długa Valley on a steep slope of ravine beneath the belt of Jurassic radiolarite cliffs. The brecccia consists of angular clasts of radiolarite bound with calcite cements. Void spaces between the clasts contain shells of Holocene snails. The cements are built of columnar crystals composed of acicular subcrystals and of skeletal crystals. The crystals grew rapidly from supersaturated solution due to CO2 degassing. Cementation occurred in vadose conditions in the Atlantcic Phase soon after the scree formation.
