Harmonizing classifications of cohesive soils according to PN-EN ISO 14688:2006 and PN-86/B-02480 standards
No full textThis article discusses the differences between the classification of cohesive soils according to the obsolete PN-86/B-02480 Polish standard and to the applicable PN-EN ISO 14688:2006 standard. Differences in the ways of recognizing and classifying these soils according to these standards are debated in the scientific and professional world, and due to the different approach to their nomenclature they seem difficult to overcome. The author analyzes these Polish research methods, which are closest to the macroscopic analysis required by PN-EN ISO 14688:2006, and then points to the real possibility of harmonizing both classifications
Engineering soil classification according to EN ISO 14688-2:2018
Get PDFThis paper presents novelties in the identification and description of soil according to European standard EN ISO 14688-1:2018, as well as changes in the principles of soil classification according to European standard EN ISO 14688-2:2018. A new version of the European Soil Classification System (ESCS) for engineering purposes is developed. A detailed comparison with the Unified Soil Classification System (USCS) is performed according to soil group symbols, soil group names, and soil classification procedures. A new version of the KLASIF computer software is also developed. The program provides IT support for implementing both USCS and ESCS classifications, and facilitates their parallel use
Identification, description and classification of soil acc. to standards PN-EN ISO 14688-1 and 14688-2
No full textThe article introduces the methods of identification, description and classification of soils presented in the PN-ENISO14688-1 andPN-EN ISO 14688-2 standards. Experience shows that these standards, although referred to by Eurocode 7, are still not fully implemented and are most often applied incorrectly. In practice, the soil is still identified macroscopically using the principles presented in the withdrawn PN-B-02480:1986, PN-B- -02481:1998 and PN-B-04481:1988 standards
Critical remarks on soil classification in conformity with the standard PN-EN ISO 14688:2006
No full textPrzedstawiono główne błędy, niespójności i niedopowiedzenia zauważone w klasyfikacji gruntów według PN-EN ISO 14688:2006. W normie tej występują trzy grupy usterek: A – usterki, nieścisłości, niedopowiedzenia, które zauważono w wersji oryginalnej ISO; B – usterki wynikające z niedokładnego tłumaczenia; C – usterki występujące w załączniku krajowym. Zasadniczymi błędami w grupie A są: niespójność określenia nazwy gruntu według rozpoznania makroskopowego i na podstawie krzywej uziarnienia oraz nieprawidłowości w klasyfikacji stanów gruntów spoistych. Wykazana została niemożność prostego przejścia z nazwy gruntu według PN-86/B-02480 na nazwę gruntu według PN-EN ISO 14688:2006. Sytuacje powyższe zilustrowano przykładami graficznymi i liczbowymi. Ponadto omówiono wiele innych drobniejszych usterek i przedstawiono ogólną ocenę normy.The paper presents main errors, incoherencies and understatements noticed in soil classification in conformity with the PN- EN LSO 14688:2006. Three groups of defects have been observed in the PN-EN ISO 14688:2006: A- defects, imprecision, understatements noticed in the original ISO version; B- defects resulted from inaccurate translation; C- defects observed in the Polish Appendix. The main errors of A group have been as follows: incoherencies in definition of soil name according to macroscopic analysis and on the basis of grain-size distribution curve as well as incorrectness in classification of states of cohesive soils. The impossibility of simple transfer from the soil name in conformity with the PN-86/B-02480 to the soil name in conformity with the PN-EN ISO 14688:2006 has been demonstrated. The adequate graphical and numerical examples have been included. In addition numerous minor defects have been discussed. The general assessment of the standard under reference has been presented
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
