    Taxonomic inconsistencies between two published collections on Devonian stromatoporoids were examined. The studied collections contain stromatoporoids sampled from the Middle and Upper Devonian from the Ardennes (collection by Lecompte) and the Holy Cross Mountains (collection by Kazmierczak). The study was limited to stromatoporoid species that were assigned to the order Stromatoporellida. At least eight species which were described from the Devonian of both the Ardennes and the Holy Cross Mountains should be revised: F. ruedemanni, H. crassum, H. porosum, H. perseptatum, S. lensiforme, S. socialis, T. laceratum, T. pingue . Specimens that were assigned to C. damnoniensis, C. spissa, H. episcopale, H. schlueteri, P. cellulosum and S. huronense do not need to be revised. The inconsistencies may severely influence the outcome of palaeogeographic and biodiversity studies, since the error in not distributed randomly among stratigraphic intervals and it affects classification at the genus-level

    The rovibrational electric dipole transitions in the ground electronic state of the HD molecule are studied. A simple, yet rigorous formula is derived for the transition rates in terms of the electric dipole moment function D(R)D(R), which is calculated in a wide range of RR. Our numerical results for transition rates are in moderate agreement with experiments and previous calculations, but are at least an order of magnitude more accurate.Comment: 7 pages, 1 figur

    Heterotopias of Nationalist Youth Organisations in Poland: Communitarisation and Entry/Exit System

    Get PDF
    The article presents the results of an analysis of the discourse of nationalist youth organisations in Poland. The authors have attempted to reconstruct the common “us” of two youth organisations based on the materials made available by them as well as articles in the press published in 2018 in selected journals and weeklies. This was the year when Poland celebrated its 100th anniversary of regaining independence, which made this an exceptional time in the context of discourse about the community. The article focuses on two youth organisations – the All-Polish Youth (APY) and the National Radical Camp (NRC). The study answers the question of how the “us” community is construed within the organisation, what are its dimensions, and are they places where the two heterotopic principles are implemented: (1) The principles of openness and closedness of a community or communities, and (2) the rules for compiling several different heterogenous spaces within one organisation. This article was prepared within a research project which is in line with the so-called topographical turn in discursive research and refers particularly to the concept of heterotopia of Michel Foucault. The research showed that the discursive constructions of youth communities reflected these two heterotopic principles

    VHR images of earths ’ surface are more frequently used and taken advantage of in substitution to aerial photographs. Geometric dependences of creation orthophoto based on aerial photos are known and distinguished from images of VHR. Results of work led are presented in this article within the confines of an investigative project under the Committee of Scientific Research of Poland concerning the geometric mechanism of VHR images and corrections. Two test fields have been made up for this project (city, country and mountain terrain). For those test fields, images from IKONOS, QuickBird were ordered. In the conducted research the angle of the axes was take into consideration: 0 ° – 15 ° In each test field area, after the identification of control points on the VHR images, about 30 – 90 GCP have been measured with GPS in accuracy of 10 cm. For image geometric corrections in this project two types of available DTM models in Poland have been applied with varying accuracy. Geometric correction have been realized with the aid of generally available software as PCI Geomatica 9 with taking into consideration RPC method and camera ( rigorous) model. Throughout the work investigated, in each of the individual scenes of VHR various distribution and number of GCP was utilized for the process of orthorectification. Accuracy of orthorectification process received in result of led work, for VHR images at different configuration of geometry and methodology. Detailed results of experiments allow determining the optimal foundation for different methods of geometric corrections from IKONOS, QuickBird images and establishing effective process of dependence and defining geometric accuracy for different applications. 1

    Boredom proneness and fear of missing out mediate relations between depression and anxiety with problematic smartphone use

    Full text link
    Depression and anxiety severity are found in numerous studies to correlate with increased levels of problematic smartphone use. Yet there are less available data on other psychopathology‐related correlates of such use. Two potentially important variables related to depression and anxiety, and recently found related to problematic smartphone use severity, are boredom proneness and the fear of missing out (FOMO). Our aims were to (a) assess boredom proneness and FOMO in relation to problematic smartphone use severity and (b) assess the mediating roles of boredom proneness and FOMO in relationships between depression/anxiety severity with problematic smartphone use severity. We recruited 297 American college students for a web survey, assessing constructs including FOMO, boredom proneness, depression, anxiety, problematic smartphone use, and smartphone use frequency. We tested a structural equation model to assess relations between depression and anxiety severity with boredom proneness and FOMO, and relations between these psychopathology constructs with levels of smartphone use frequency and problematic use. Results demonstrate that FOMO was significantly related to problematic smartphone use severity. FOMO also mediated relations between boredom proneness and problematic smartphone use severity. Furthermore, boredom proneness and FOMO serially mediated relations between both depression and anxiety severity with problematic smartphone use severity. Results are discussed in the context of Compensatory Internet Use Theory and the I‐PACE model in understanding factors driving problematic smartphone use.Peer Reviewedhttps://deepblue.lib.umich.edu/bitstream/2027.42/153150/1/hbe2159.pdfhttps://deepblue.lib.umich.edu/bitstream/2027.42/153150/2/hbe2159_am.pd

    Framing the Holocaust in popular knowledge: 3 articles about the Holocaust in English, Hebrew and Polish Wikipedia The goal of this article is to examine how different events and phenomena related to the Second World War and the Holocaust are framed via Wikipedia articles written in Polish, Hebrew and English. Departing from the pillars of the theory of framing in mass media, the article conducts a content analysis of three articles, in three different languages. The articles under analysis are the following: “Auschwitz-Birkenau Camp”, “The Pogrom in Jedwabne”, and “Righteous Among the Nations”. The analysis will use the four roles of frames as categories, determined by Entman: definition of the problem/phenomenon, causal interpretation, moral evaluation, and treatment recommendation. Analyzing how the articles fulfill each of the roles in the different languages, the research hypothesis is that the framing of the phenomena will differ between the versions, and each version will follow pillars of the collective memory of the Holocaust in its respective country. Findings, however, are not in complete compliance with this hypothesis.   Kształtowanie popularnej wiedzy o Holocauście na przykładzie trzech artykułów z polskiej, hebrajskiej i angielskiej Wikipedii Celem artykułu jest zbadanie, jak przedstawiane są wybrane wydarzenia i zjawiska, związane z historią II wojny światowej oraz Holokaustem, w internetowej encyklopedii „Wikipedia” w różnych językach. Prezentowana analiza treści opiera się na teorii framingu w mass mediach i obejmuje trzy artykuły: „Auschwitz-Birkenau”, „Pogrom w Jedwabnem” oraz „Sprawiedliwy wśród Narodów Świata”, opublikowane w językach polskim, angielskim oraz hebrajskim. W analizie wykorzystano cztery role „ram” (frames), sformułowane przez Entmana: definicja problemu/zjawiska, interpretacja przyczyn, ewaluacja moralna oraz propozycja rozwiązań. Autor, badając to, jak poszczególne artykuły wypełniają każdą z tych ról, stawia hipotezę, zgodnie z którą teksty przedstawiają ten sam temat w różny sposób, w zależności od podstaw pamięci zbiorowej w danym kraju. Wyniki badań jednak nie zawsze są zgodne z tą hipotezą

    The Act of 4 February 2011 on Care for Children up to the age of 3 significantly changed the childcare system in Poland and one of its aims was to support parents in managing work, family and private life. The article presents an analysis of the press debate on family policy in Poland in the years 2010-2015, with a focus on care systems for children up to 3 years of age. The author tries to answer the following research questions: what was the impact of the analyzed press debate on the design and implementation of the Act of 4 February 2011? Whose interests were exposed mostly? What was the context of the legal changes and whose interests were presented? And finally, what and how family issues were discussed, and how were the childcare system addressed to the youngest children and the new legislation described? Five press titles were analyzed: two daily newspapers „Gazeta Wyborcza” and „Rzeczpospolita”, and three weeklies - „Do Rzeczy”, „Polityka” and „Newsweek Polska”.Ustawa z dnia 4 lutego 2011 roku o opiece nad dziećmi w wieku do lat 3 istotnie zmieniła system opieki nad najmłodszym dzieckiem w Polsce, a jednym z jej celów było wsparcie rodziców w godzeniu obowiązków zawodowych z rodzinnymi. Artykuł przedstawia analizę przebiegu debaty prasowej na temat polityki rodzinnej w Polsce w latach 2010‒2015 ze szczególnym uwzględnieniem wątków poświęconych opiece nad dzieckiem w wieku do lat 3. Autorka próbuje przede wszystkim odpowiedzieć na pytania ogólne o to, jaki był wpływ analizowanej debaty prasowej na projektowanie i wdrażanie tzw. ustawy żłobkowej? Czyje interesy zostały najsilniej wyeksponowane? A także, jakie zagadnienia związane z rodziną były podejmowane przez poszczególne tytuły prasowe i jak o nich pisano, jak pisano o zmianach w systemie opieki nad dzieckiem do lat 3 i samej ustawie, jaki był kontekst tych zmian i czyje interesy zostały przedstawione. Analizie poddano łącznie pięć tytułów prasowych: dwa dzienniki – „Gazetę Wyborczą” oraz „Rzeczpospolitą” i trzy tygodniki – „Do Rzeczy”, „Politykę” i „Newsweek Polska”
