Nikulicheva, Dina B. "Declared vs practiced strategies by polyglot Steve Kaufmann." Journal of Psycholinguistic, no. 2 (June 30, 2023): 58–67. http://dx.doi.org/10.30982/2077-5911-2023-56-2-58-67.
Full textAbstract:
Based on the study of the works of the Canadian polyglot Steve Kaufmann, a new aspect in the study of polyglottery is proposed: a comparison of linguodidactic principles that polyglots themselves formulate in their publications with those specific language learning strategies that can be identified by analyzing the language platforms created by polyglots to teach other people. In particular, the article studies conscious and unconscious attitude of polyglots to authentic educational materials and designed courses; ways of mastering grammatical forms, communication with the real and imaginary world, the use of parallel texts when learning new languages, the use of regional variants, varying the speed of educational audio materials, the use of special technical approaches to increase the motivation and optimize students’ time management.

Full textAbstract:
The article focuses on the human individual as a signifying and communicating self whose properties can be detected or assumed on the basis of its language in verbal communication through texts and text-processing activities or, more broadly, in both verbal and non-verbal communication through signs and sign-processing activities in the semiotics of culture. The point of departure is the distinction between the observable self and the inferable self, i.e., a concrete person who transmits and receives verbal and/or non-verbal messages, and a mental subject who is engaged in creating and comprehending them. As a consequence of this distinction, it can be stated that the communicative network of the human life-world consists of two types of collectivities. On the one hand, there are speakers and listeners of particular languages who form interpersonal collectivities of those transmitting and receiving perceivable meaning bearers through physical-acoustic sound waves in the communication channel; on the other hand, there are intersubjective collectivities of those who process and understand intelligible meaning bearers while referring them to an extra-linguistic reality through acts of reasoning and interpreting. Exposing the notion of polyglotism, this paper argues that a multiaspectual typology of selves is possible on the basis of the linguistic and cultural texts that characterize the social roles and pragmatic goals of communication participants in the various domains of the human life-world. Finally, it supports the conviction that interdependencies between language and culture must be primarily explained in terms of psychological, or rather, psycho-semiotic conditionings of humans. Since particular languages are products and components of social and cultural life, constantly being shaped and changed due to personal and subjective activities of human selves, polyglotism as both multilingualism and multiculturalism also implies an inquiry into their multicultural competence and multicultural identity.

Full textAbstract:
A contact language called Broken Slavey or Slavey Jargon flourished among the Gwich’in in the nineteenth century. Slavey Jargon absorbed elements of at least five source languages: French, Gwich’in, South Slavey (Dene-Tha’), Chipewyan, and English. Analyzing historical sources and recorded ethnographic texts from fluent speakers of Gwich’in, I offer an explanation of how the lexicon and grammar of this kaleidoscopic language converged regionally in the small subarctic communities of Fort McPherson, La Pierre’s House, and Fort Yukon. I also conclude that there is no internal textual evidence that Slavey Jargon was used as a trading pidgin. The polyglot form of most Slavey Jargon texts represents a curious inseam of linguistic democracy, suggesting that a measure of social equality was negotiated between the speakers of its diverse component tongues.

Buddhist Studies scholarship in general, and its (re)turn to the literary specifically, is overwhelmingly concerned with texts and authors. But what can this research into “Buddhist texts” and “Buddhist authors”, however robust, ever reliably tell us if not accompanied by comparative inquiry into the destabilizing tactics of readers? This article first highlights analytical resources for a comparative history of reading Buddhist literature in Inner Asia by looking to the work of Michel de Certeau and Roger Chartier. I then turn to a case study of collaborative reading that developed across the contiguous monastic and imperial networks binding together Tibetan, Mongolian, Manchu, and Chinese readers at the turn of the 18th century. Focused specifically on letter exchanges between the polyglot scholars Güng Gombojab, Katok Tséwang Norbu, and Situ Paṇchen, I underscore how collaborative reading developed to open the literary heritage of trans-Eurasia beyond the technical abilities or material access of any single reader.

Full textAbstract:
The paper investigates the question of self-translation in the work of Alexander Lenard (Lénárd Sándor). Lenard, a polyglot writer and translator, rewrote his autobiography three times, in three different languages (in German, English, and Hungarian). This process of self-translation created a fascinating web of autobiographical texts, which invite a multiscopic reading. Following in the footsteps of 18th century parodists, Lenard challenges a great number of protocols associated with life-writing. The most important among these is the authority of the proper name as a guarantee of autobiographical authenticity. To challenge the authority of the proper name Lenard purposely multiplies his own authorial identities, for example by claiming that “A. L. is only a pseudonym.” Thus, the word ‘self-plagiarism’ acquires in Lenard’s case a double meaning, implying both that the author plagiarizes his own text and that he plagiarizes his own self. The paper explains why existing theories of self-translation cannot be applied to Lenard’s texts, and why his unique case can enrich future studies of this topic.

Full textAbstract:
Translation is an age-old activity which occupied a part of all regional literatures since the past. The retracement can be traced to the times of the great epics as The Ramayana and The Mahabharata. India has been a multilinguistic, polyglot nation with translations from Sanskrit, Prakrit and Pali into many regional languages. Translation brings to the readers not just the meaning and context but also the cultural, social, philosophical, and psychological truths inherent in those texts and their transfer to the new language into which the text is translated. The present article attempts to reveal a few facets of Indian translations in literature and its impact on readers. This paper also focuses on the nature of translation by Indians done using translation as a tool of transformation of literature contributing to the language pantheon.

Full textAbstract:
Genres travel in multiple directions. This article maps the evolution and movement of two lyric genres in Georgia, a small nation situated south of the Caucasus mountains, between Russia, Turkey, and Iran. The mukhambazi arose from a polyglot urban culture rooted in Near Eastern traditions of bardic performance and festivity, while the sonnet was imported around the time of the Russian Revolution as a marker of European modernization. The brief coexistence of these two genres allows for a reexamination of the foundational opposition between East and West. Moving beyond the familiar dichotomy of tradition and modernity, this essay explores the texts and debates of more than a century, reconstructing the discrepant cosmopolitanisms and multiple modernities that typified the Caucasus region. In doing so, it seeks both to make available a literary archive unknown to American readers and to contribute to ongoing debates on the relations between the local, the national, and the imperial as cultural formations.

Full textAbstract:
A Modernist at heart, writing in the wake of the polyglot tradition firmly established in the first half of the twentieth century by Joyce's operatic Babels and Pound's symphonic Cantos, Robert Lowell was a poet who spoke in many voices, a master of linguistic personae. Switching with baffling ease from the “otherworldly” Puritanic gloom shrouding his recreation of his New England ancestors, to the very worldly evocation of his own personal life, he was a writer with a keen ear for layering various types of discourse within the span of one poem. What is more, as was the case with Joyce or Pound, his mastery of tone and voice enabled him to let his readers overhear what I am tempted to call a “cultural polyphony” sounding in each of his texts, in the fleeting utterance of one single word — or better still, as I hope to demonstrate, in the discreet note of one syllable, one letter.

Full textAbstract:
Summary: European painters’ writing activities may be seen as an intent of “heteropoetry” with the aim of revealing aesthetic experience in a linguistic mode that avoids the traditional problem of visual art as representation of external reality. Henceforth, poetry becomes a privileged medium of expression of an imaginary which in Renaissance and Baroque art and literature is centered on the Neo-Platonist concept of “idea” (cf. Panofsky, Hocke). Studying the texts of surrealist painters, four aesthetic levels to perform poetic subjectivity can be detected. At the early beginning of 20th century, the poems of Dalí and Chirico absorb the tradition of inner landscape as a medium to reflect the painter’s perception processes as a manner of scanning older aesthetic and rhetoric features. Along with this concept of lyric texts as mechanisms to reproduce the subject’s imaginary, we find the concept of acoustic sculptures, such as the poems of Giacometti. These are characterized by a highly inventive manner of deforming standard language by means of foreign language structures referring to the poet’s polyglot education. The concept of “moving pictures” which may well be inspired by the ascent of cinematography is to be found in the poetry of Joan Miró. This type of painter’s texts may be described by its pictorial volatility pouring in an imagery which is close to the aesthetic procedures of surrealism such as the cadavre exquis. As a last level of poetic features we analyze are the various types of “linguistic hurdles”, represented by different kinds of puns (Max Ernst, Duchamp), linguistic fragmentation (Picabia) and semiotic meta-reflection (Magritte) which finally deconstruct the old contract between inner vision and outward reality.

Full textAbstract:
Shop and café signs in multiple languages are familiar features of polyglot immigrant neighborhoods. This paper examines such signs, presenting photographic, observational, and interview data from a multisited ethnographic study of language contact in Ghent, an urban Belgian city. Drawing upon diverse ethnographic sources, especially the comparative readings of foreign, immigrant, and native adults, we analyze signs and notices in several immigrant neighborhoods as (a) literacy practices, attending to their contexts of use as well as to their interpretations, and as (b) examples of indexical orders and orders of discourse, asking what hierarchical frames of interpretation and evaluation are brought to bear on the reading of such signs. Our findings show that shop signs and notices are complex indexes of source, addressee, and community, which are manifest in different readers' interpretations. The overall argument addresses several general points: that the study of indexicality helps conceptualize and analyze the rich and unexpectedly broad frames of interpretation readers bring to situated multilingual texts; that concepts of indexical or discursive order contribute to our understanding of multilingual literacy practices in situations of globalized locality; and that, conversely, the study of literacy practices reveals unexpected dimensions of Late Modern discursive orders.

Full textAbstract:
Elizaveta Borisovna Kul’man (1808-1825) is a unique figure in the history of Russian literature, or more precisely, the history of Russian, German, and Italian literature. A child prodigy with formidable linguistic gifts, Kul’man stands out both with her polyglot prowess and outsized literary productivity. At the time of her premature death at age seventeen, Kul’man left behind a vast unpublished oeuvre in multiple languages. The edition of her works published by the Imperial Russian Academy in 1833 contains a trilingual compendium of hundreds of parallel poems written in Russian, German, and Italian. The writing of poetic texts in three languages simultaneously makes Kul’man an early practitioner of what has been called “synchronous self-translation”. Not only are the poems linked horizontally as mutual translations of each other, they also pose as translations of a fictitious Greek source. Kul’man thus combines translation, self-translation, and pseudo-translation into a unified whole. This article discusses the genesis of Kul’man’s translingualism and explores her trilingual poetics in more detail by following the metamorphosis of one particular poem through its incarnations in Russian, German and Italian. It argues that Kul’man’s translingual creativity anticipates more recent developments in twentieth and twenty-first-century poetry produced by globally dispersed Russians.

Full textAbstract:
For English teachers listening fluency is a fundamental competency for their professional development. Listening is one of the most complicated and problematic aspects of learning English, as it leads to high mental strain. The objective of the research is to study mobile learning as a means to improve listening comprehension skills of the future English teachers. The tasks of the research are as follows: to identify and work out the theoretical framework for mobile applications use and their role in teaching English; to present the pilot study of the role of mobile learning in students’ autonomous work, in particular for listening comprehension skills improvement. The following methods were used: theoretical (theoretical-and-methodological analysis, classification and systematization of scientific sources, comparison and generalization of the theoretical and experimental research data), empirical (observation, testing), data processing methods (generalization and systematization of qualitative and quantitative results of the empirical research); methods of mathematical statistics (evaluation of experimental data by the arithmetic mean calculation). Upon the theoretical analysis results, the categories of mobile applications and their role in teaching English were identified. The survey showed that the students use mobile learning insufficiently and ineffectively. The research on the use of mobile learning as a means to improve the future English teachers’ listening comprehension skills was conducted. This required selection of several mobile applications (Duolingo, LinguaLeo, Learning English with New York Times, Polyglot 16 EnglishPod - Learn English, Bussu), the main selection criterion being the availability of tasks and texts for listening. The results of the term listening comprehension test showed that the students of the experimental groups who studied using mobile learning scored higher than those of the control groups, which proved relevance and effectiveness of mobile learning use as a means to improve the future teachers’ of the English language listening comprehension skills.

Full textAbstract:
The article ”Show some emotion!” invites the reader to a dog-walk through the leaking and cracked up theoretical and emotional landscape of contemporary feminist academic writing. It also pays a short visit to the (in Sweden) ongoing debate on the consequences of adapting to a so called ”excellence culture”, especially for critical feminist research in the humanities and social sciences. What is the cost for ”passing”? And, due to the less debated requirements of ”writing in English” as equivalent for ”internationalisation”: what is possibly gained – and what is lost in translation, from the inside-perspective of a ”small” language/ mother-tongue such as Swedish? Along the way, the dog-walking and talking of the text finds its inspiration both in theoretical and in literary texts. It tries to make use of a hybrid, ”leaking” and experimental stylistic attitude, which strives to be both polyglot and polyphonic; both democratic and emancipatory in its effects on the reader. Thus, the overall aim of the article is to explore and challenge the notion of academic writing and knowledge production as an rational, ungendered and unemotional activity. In addition to the so-called ”surplus of knowing”, that is said to be a gain for the individual researcher, the article argues that we also ought to pay attention to the unrecognized ”emotional leakage” that occurs alongside in all intellectual work. In feminist and gender theory the emotional experiences of gendered power relations in academia have often been derived from personal and psychological factors – instead of a plausible result of an emancipatory and anti-hierarchical epistemological claim. The improductivity of the dichotomies between reason and emotions, as well as between academic and literary writing, is demonstrated, drawing on three ”emotional leakage”- situations in the works of three pathbreaking feminist theorists: bell hooks, Sara Ahmed and Donna Haraway. hook’s ”passionate feminist politics”, Ahmed’s illuminating analysis of ”the cultural politics of emotion” and Haraway’s daring challenge to use ”dog writing” as a metonym for feminist writing, altogether highligths the importance of style as method and as a potentially emancipatory strategy.

Franko in the Ukrainian culture. Creative legacy and figure of the writer are viewed in terms of various types of speech activity in the study of Ukrainian as a foreign language. Attention is drawn to the main difficulties that foreigners may experience when working with his writings and other works. It is crucial to present the author and not limit oneself solely to the use of Ivan Franko’s creative legacy in the form of written matter. Additionaly, it is worthwhile to discuss Ivan Franko at all levels and use his works as illustrations, taking into account the learning objectives and wishes of the audience. Ivan Franko’s works, which were put to music by Ukrainian artists, as well as high-quality video recordings about his life and artistic legacy, are of great help to those wishing to introduce the writer to the audience and develop their listening, speaking and writing skills. Particular attention should be brought to the 2019 film Zakhar Berkut, which is based on Ivan Franko’s novella under the same title. One of the advantages of such works is that they arouse great interest in the Ukrainian culture in general and in the figure of the writer in particular. Furthermore, dialogues in films show the use of active vocabulary and capture viewer’s attention. The most promising way of familiarizing non-Ukrainian students with Ivan Franko is by the means of his works. Creative legacy of the writer is represented by different genres and one may find the subject that might prove to be interesting for different types of readers. In the process of working with Franko’s texts, a number of difficulties may arise at the level of form and content in author’s narration. At the language level, one can name non-equivalent and culturally marked vocabulary, e.g. dialectisms, proper names, nonce words, phraseological units, obsolete words and archaisms. Clarifications on the historical and cultural context should be included in order to gain sufficient understanding of author’s works. Besides, non-Ukrainians might be interested in a graphic novel The Reluctant Hero by Kyryl Horishnii and Mikhai Tymoshenko, a two-volume graphic adaptation of Ivan Franko’s novel under the same title. Since Ivan Franko was a polyglot, he produced self-translations of his works and also originally wrote some of them in many European languages. Thus, native speakers of these languages may want to make their own translation of excerpts from Ivan Franko’s works and compare them with the author’s translation. Another way of presenting Ivan Franko is with the help of place names encountered in Lviv, the author’s city of residence. There are numerous locations that emphasize the importance of this figure to the Ukrainian history and culture. Key words: Ivan Franko, Ukrainian as a foreign language, types of speech activity, text, methodology of teaching Ukrainian as a foreign language, linguistics and country studies.

Résumé L'idéal polyglotte et l'idéal de la traduction philologique, foncièrement alliés, rêvent d'une traduction parfaite où un passeur accomplirait la translation de l'écriture du texte original. À vrai dire, toute traduction est une lecture et c'est ainsi qu'il faut en juger et en user. La tradition historique, notamment la succession des traductions, fait émerger des textes d'auteurs-traducteurs et des traductions devenues textes d'auteurs dans la durée. De toute façon, le patrimoine des traductions littéraires, mieux encore que l'héritage critique et de manière directement poétique, rend compte des potentialités exégétiques et herméneutiques des textes originaux autant que de l'histoire de leur interprétation et de leur intégration.

Ce texte vise à montrer les apports et les limites de l'anglais lingua franca pour la construction et la transmission des connaissances dans le monde de la recherche et de l'enseignement supérieur. Il présente les défis majeurs qui se posent aujourd'hui à des institutions qui veulent tout à la fois être compétitives au niveau international et valoriser leurs cultures scientifiques. Pour répondre à ces défis, il s'agit d'envisager un nouveau type de "contrat" entre la lingua franca et les langues nationales ou régionales, un contrat qui se décline tout à la fois en termes de compétences plurilingues, de "standardisation épaisse" et de conception hybride de la lingua franca. Et reste alors la question de savoir comment faire passer le message d'une telle conception du plurilinguisme; un transfert que nous voulons saisir ici en termes de "métacognition située" dans le cadre d'une linguistique "impliquée".

Full textAbstract:
Purpose:The number of familiarization sessions in fitness assessments seems to be critical and inconsistent. Therefore, the primary aim of this research was to determine the number of familiarization attempts that stabilize the results in particular physical fitness tests. The secondary aim was to establish the test reliability through familiarization sessions.Methods:Thirty-nine primary school children participated in this research (age: 10.8 years, body mass: 40.6 ± 8.9 kg, and body height: 145.3 ± 7.2 cm). During six sessions, with one session every third day, participants performed the following tests to assess explosive strength (vertical jump and standing long jump), coordination (polygon backward and polygon with turn) and flexibility (toe touch).Results:The results of repeated analysis of variance (ANOVA) showed that there were significant increases (p < .05) in the polygon backward and polygon with turn performances from the first to third familiarization session. The standard error of measurement decreased as sessions progressed, indicating little within subject variation between the coordination test results following a familiarization period. Statistically significant differences were identified in the vertical jump test from the fourth test session compared with the first session. On the other hand, statistically significant differences for the standing long jump test were only found in the final session compared with the initial session. In the toe touch test, there were no significant increases from the first to the final familiarization session. All tests showed high a reliability coefficients, ranging from 0.979 to 0.991.Conclusion:Polygon backward and polygon with turn performance may be a practical, reliable method to assess coordination in primary school-aged children. However, completion of at least 3 practice sessions is suggested for participants to obtain a stable score. In addition, both jump tests are feasible for assessing skill-related fitness in young children, although the scientific reliability of the two tests should be questioned and the tests should be tailored to fit the age group of the children.

Full textAbstract:
The monitoring of railway rails damage on the railway network of the JSC “Russian Railways” as well as operational and polygon tests are conducted with the purpose of assessing the impact of operating conditions on the intensity of rails damage, obtaining initial data for forecasting rails failures. The increased intensity of rails wear on sites with a complex plan and profile leads to the fact that with a continuous change from the track, rails which have an underutilized service life of more than 20 % are retrieved. Polygon tests on the Test Loop of the JSC “VNIIZhT” near the Scherbinka station can provide the repeatability and reliability of the results, comparative tests are carried out under identical conditions and their duration is several times less than when tested at experimental sites under operational conditions. The results of the polygon tests of new differentially heat-strengthened rails did not reveal any advantages in the wear resistance of special purposed rails (laid in the recommended radius of the curve for its application) when comparing the rails of domestic manufacturers. Metal shelling out on the rolling surface of rails is the main reason for the removal of rails from test batches. The origin and development of defects of this kind is due to both violations of the technology of manufacturing rails, and because of violations of the current maintenance of the track. The metal stock in the area of the rail head of R65 type due to the increase in its dimensions positively affects the extension of the lifetime of the rails, reducing the cost of the life cycle and the rail itself, and the design of the track as a whole. When carrying out a separate study in order to obtain results characterizing the stability of high-quality rails to contact fatigue damage, it is advisable to optimize the conditions of the polygon tests, bringing them closer to operational ones. When forming the test results, it is necessary to expand the list of criteria for assessing the wear resistance of rails, supplementing it with the size of the wear area at the time of a certain operating time of the tonnage, with the introduction of this criterion into the appropriate methods for the polygon (operational) tests.

Abstract Random access codes (RACs) are an intriguing class of communication tasks that reveal an operational and quantitative difference between classical and quantum information processing. We formulate a natural generalization of RACs and call them random access tests (RATs), defined for any finite collection of measurements in an arbitrary finite dimensional general probabilistic theory. These tests can be used to examine collective properties of collections of measurements. We show that the violation of a classical bound in a RAT is a signature of either measurement incompatibility or super information storability. The polygon theories are exhaustively analysed and a critical difference between even and odd polygon theories is revealed.

Full textAbstract:
In this paper we report on our attempt to teach the polyglot savant Christopher (‘C’ hereinafter) British Sign Language (BSL). BSL presents C with a novel challenge in the use of hand-eye coordination, while at the same time offering him the linguistic ingredients he is obsessed with. Despite his deficits in key areas of intellectual ability, communication skills and visuo-spatial cognition, C has developed a working knowledge of BSL through processes of circumvention, adaptation and invention. As a form of control, we taught BSL to a comparator group of talented second-language learners. We do not discuss this comparison in depth here (see Morgan et al. in preparation) but refer to some of the test scores as a guide to how normal a sign learner C is.Results from formal tests of C's linguistic knowledge, and observational study of his developing communicative ability in BSL, are analysed and described. These results illuminate the structure and use of BSL, highlighting the important role of visuo-spatial cognition in its acquisition and manipulation.Our findings support the assumption that the organisation of knowledge of language is largely modality independent, whereas the exploitation of specific grammatical devices is language and modality dependent. C has attained a certain level of linguistic competence in BSL, and his performance in the language is largely in conformity with his previously established mixed profile of abilities and disabilities.

The introductory part of the article provides information that JSC "Element" is one of the leading enterprises of Ukraine in the scientific and technical direction "Electronic systems for measuring, monitoring parameters and aircraft engine control". As a result of cooperation between the team of Element JSC and a number of divisions of Motor Sich JSC, software and hardware complexes (SHC) were developed to automate the technological processes of bench tests of aircraft engines. For 15 years, about 20 such SHCs have been supplied to Motor Sich JSC and other enterprises. An important task of Element JSC was to provide support for its hardware and software complexes, to promptly resolve issues related to their performance and modernization as new requirements and technological processes emerge. The SHC Polygon became the main tool in solving these problems. The description of the SHC Polygon is given, which is a functionally standard SHC, but with a reduced composition of measuring modules. The SHC polygon consists of two hierarchical levels: lower and upper. The upper level of the PTK Polygon is a device for communication with the object, the main tasks of which are the transformation of parameters coming from the sensors and the primary processing of information, control of technological operations, and emergency protection of the engine. The upper level is two workstations that display information and provide interaction between the operator and the system. The Polygon SHC includes a software product (SP) operating in the environment of the QNX 4.25 real-time operating system. The main feature of the SHC Polygon is the ability to launch the SP of any of the developed SHC, adapted to work with the existing set of measuring modules. A list of the most frequently performed works in the course of post-warranty maintenance of the hardware and software complex, including the introduction of new technological operations and algorithms, is given. It is noted that the SHC Polygon turned out to be a successful solution for remote support of aircraft engine tests at the stands of Motor Sich JSC. It allows you to solve most of the problems identified in the operation of the equipment of test stands and hardware and software systems, and also provides modernization and refinement of algorithms without specialists visiting the site. The possibility of remote maintenance of the SHC is especially important in the context of the Covid-19 pandemic and quarantine restrictions in Ukraine.

Three different polygon morphing methods are examined. The first one is based on the utilization of the trimmed skeleton of the symmetric difference of the source and target polygons as an intermediate polygon. The second one reduces the problem to the problem of morphing compatible planar triangulations and utilizes the representation of planar triangulations as a matrix constructed using barycentric coordinates of the planar triangulation's vertices relative to their neighbors. The third and last one describes the polygon by the parametric curve representation based on estimated Fourier parameters and thus transfers the morphing process to Fourier parametric space. The different features and comparative results of these methods are shown by the tests with different examples. These methods are used for generating a set of polygonal sections from two nonplanar polygonal sections which are nearly planar in 3D before constructing a three-dimensional object from these nonplanar sections.

RésuméDeux éditions bibliques – l’Ancien Testament ou Bible de Ferrare de 1553 et le Nouveau Testament polyglotte composé par Guy Le Fèvre de La Boderie en 1584 – sont analysées du point de vue des stratégies éditoriales et de la matérialité des oeuvres dans le contexte des querelles religieuses du XVIe siècle. L’examen des deux dossiers permet de trouver les traces des effets voulus ou non par les opérations de publication du texte sacré, sur le plan des significations, qui permettent de découvrir une dialectique entre les déterminations sémantiques et les libertés interprétatives autour des processus de production et de lecture du texte biblique. L’insertion d’un troisième dossier concernant les éditions canoniques sixtine et clémentine de la Vulgate présente de forts contrastes avec les deux premiers, en même temps que l’on ne cesse de s’y heurter à des instabilités inattendues de la signification.

Abstract. The paper discusses the importance of efficient methods in the automotive industry for the development of self-driving vehicles and advanced vehicle assistants, focusing on the use of high-definition (HD) maps. The integration of computer simulation and HD maps in the OpenDRIVE format is emphasized. A paradigm shift in map topology is highlighted, requiring a new map creation and usage approach. The article presents a methodology that addresses both geometric and topological aspects in creating accurate HD map models. The method focuses on the connection of linear and arc road elements and eliminating continuity/connectivity errors in lane descriptions. Real-world tests validate the implemented methodology and demonstrate the successful generation of topologically correct HD map models. The results show the potential of these models for various automotive applications, particularly in the development and testing of self-driving vehicles and advanced vehicle assistants. The methodology contributes to the advancement of HD map creation, providing valuable insights for researchers and map makers in the automotive industry.

Full textAbstract:
Clipping, as a fundamental process in computer graphics, displays only the part of a scene which is needed to be displayed and rejects all others. In two dimensions, the clipping process can be applied to a variety of geometric primitives such as points, lines, polygons or curves. A line-clipping algorithm processes each line in a scene through a series of tests and intersection calculations to determine whether the entire line or any part of it is to be saved. It also calculates the intersection position of a line with the window edges so its major goal is to minimize these calculations. This article surveys important techniques and algorithms for line-clipping in 2D but it also includes some of the latest research made by the authors. The survey criteria include evaluation of all line-clipping algorithms against a rectangular window, line clipping versus polygon clipping, and our line clipping against a convex polygon, as well as all line-clipping algorithms against a convex polygon algorithm.

Abstract. Freeze/thaw (F/T) processes can be quite different under the various land surface types found in the complex tundra of the Arctic, such as polygonal tundra (wet center and dry rims), ponds, and thermokarst lakes. Proper simulation of these different processes is essential for accurate prediction of the release of greenhouse gases under a warming climate scenario. In this study we have incorporated the water layer into a dynamic organic soil version of the Terrestrial Ecosystem Model (DOS-TEM), having first verified and validated the model. Results showed that (1) the DOS-TEM was very efficient and its results compared well with analytical solutions for idealized cases, and (2) despite a number of limitations and uncertainties in the modeling, the simulations compared reasonably well with in situ measurements from polygon rims, polygon centers (with and without water), and lakes on Samoylov Island, Siberia, indicating the suitability of the DOS-TEM for simulating the various F/T processes. Sensitivity tests were performed on the effects of water depth and our results indicated that both water and snow cover are very important in the simulated thermal processes, for both polygon centers and lakes. We therefore concluded that the polygon rims and polygon centers (with various maximum water depths) should be considered separately, and that the dynamics of water depth in both polygons and lakes should be taken into account when simulating thermal processes for methane emission studies.

A concrete box culvert with a dimension of 2.1 x 2.1 m and a concrete pipe culvert of 0.9 m diameter founded on soft soil were experiencing soil settlement causing undulation and discomfort to the traffic users. Voids that appeared beneath the culvert foundations triggering the road surface to sag. Objectives of the study are to assess the settlement of culverts underlain by soft soil using PLAXIS simulations on the initial subsoil conditions, after rehabilitation works with Polygeo foam injection and to evaluate the performance of Polygeo foam as a rehabilitation method. The settlement of the culverts underlain by the soft soil will be determined using finite element model based on the data and information obtained from geoforensic assessments including 12 nos. of deep borehole as well as soil laboratory tests. There were six culverts area undergone settlement problem, with two boreholes were executed at the side of each culvert. Throughout the five-year period of Post Construction stage with Polygeo rehabilitation works, the pipe culvert was shown to settle around 22 mm whilst the box culvert with pile settled around 14 mm. The study concluded that the rehabilitation works using Polygeo foam has been successfully reduced the rate of settlement and complied to JKR settlement criteria.

Mathematical representation is an idea interpretation form of solving mathematical problems. The process of mathematical representation is essential to pay attention to, especially in carrying out transformations between forms of representation, because it impacts the final solution obtained. This study describes the flow of students' thinking in carrying out the transformation process from visual to symbolic representation. This descriptive research was carried out with a qualitative approach. This research phase includes preparing representation tests and interview guidelines, giving tests to 48 students, conducting interviews with selected students based on the accuracy of the mathematical representations produced, and evaluation. The evaluation is carried out by reducing the results of the incorrect representation test, presenting visual and symbolic representation data and the transformation process, and concluding the transformation process. The result of the transformation process from visual to symbolic representation in solving the problem of the area under the curve is carried out with a flow of thought, namely translating the shape of the polygon area into a collection of rectangles, determining the width and length of the partition of the polygon area, and determining the area of the polygon area as a collection of rectangles. In determining the area as a collection of rectangles, there are two different processes, making a mathematical model in the form of sigma notation and addition. This study provides insight into the flow of thinking in changing between forms of mathematical representation in the hope that it can anticipate errors in solving the broad problem under the curve.

Full textAbstract:
Microwave remote sensing such as soil moisture active passive (SMAP) can provide soil moisture data for agricultural and hydrological studies. However, the scales between station-measured and satellite-measured products are quite different, as stations measure on a point scale while satellites have a much larger footprint (e.g., 9 km). Consequently, the validation for soil moisture products, especially inter-comparison between these two types of observations, is quite a challenge. Spatial autocorrelation among the stations could be a contribution of bias, which impacts the dense soil moisture networks when compared with satellite soil moisture products. To examine the effects of spatial autocorrelation to soil moisture upscaling models, this study proposes a spatial analysis approach for soil moisture ground observation upscaling and Thiessen polygon-based block kriging (TBP kriging) and compares the results with three other methods typically used in the current literature: arithmetic average, Thiessen polygon, and Gaussian-weighted average. Using the Texas Soil Observation Network (TxSON) as ground observation, this methodology detects spatial autocorrelation in the distribution of the stations that exist in dense soil moisture networks and improved the spatial modeling accuracy when carrying out upscaling tasks. The study concluded that through TBP kriging the minimum root-mean-square deviation (RMSD) is given where spatial autocorrelation takes place in the soil moisture stations. Through TBP kriging, the station-measured and satellite-measured soil moisture products are more comparable.

Full textAbstract:
A challenging aspect of scene text detection is to handle curved texts. In order to avoid the tedious manual annotations for training curve text detector, and to overcome the limitation of regression-based text detectors to irregular text, we introduce straightforward and efficient instance-aware curved scene text detector, namely, look more than twice (LOMT), which makes the regression-based text detection results gradually change from loosely bounded box to compact polygon. LOMT mainly composes of curve text shape approximation module and component merging network. The shape approximation module uses a particle swarm optimization-based text shape approximation method (called PSO-TSA) to fine-tune the quadrilateral text detection results to fit the curved text. The component merging network merges incomplete text sub-parts of text instances into more complete polygon through instance awareness, called ICMN. Experiments on five text datasets demonstrate that our method not only achieves excellent performance but also has relatively high speed. Ablation experiments show that PSO-TSA can solve the text’s shape optimization problem efficiently, and ICMN has a satisfactory merger effect.

The welded bogie frame is the critical safety part of the urban metro vehicle. This paper focuses on finding out the factors inducing the fatigue cracks initiated from the positioning block weld toe of metro bogie frame. Fracture morphology and metallographic analysis were conducted to identify the failure modes, and on-track tests about the dynamic stress at the positioning block weld toe and vibration acceleration were performed. The typical signals of dynamic stress and acceleration were analyzed from time and frequency domain. The relationship between wheel polygon, rail corrugation, running speed and dynamic stress in amplitude and frequency are investigated in details. Research results show that the micro cracks induced by welding at the weld toe of positioning block propagate to the spring sleeve under relatively high alternating dynamic stress, which is strongly influenced by the wheel polygon, rail corrugation and the train running speed.

Full textAbstract:
Within the latest decades a general trend has been manifested in the texts of the Russianspeaking writers of Kazakhstan: a comprehensive rethinking of the recent Soviet past in the context of national tradition and self-identification Kazakhstan’s people today. To study and analyze this trend, the stories of the following nine modern Kazakhstani authors were thoroughly selected: A. Sakhariev, R. Kunbaev, G. Doronin, N. Chernova, B. Kanapyanov, S. Nazarova, A. Omar, I. Odegov, and E. Klepikova. The signs of a local Kazakh text are revealed in the writings of these authors, where the patterns coexist and compete with each other, thus fixing the unique national Kazakh picture of the world, on the one hand, and the Soviet realities, on the other one. The analysis of the texts was aimed to clarify the outcomes of the cultural “dialogue” between traditional, deeply existential Kazakh culture and the imposed one - initially Russian, then the Soviet culture. Thus, the main question reads as follows: does this “dialogue” lead to the obliteration of the cultural boundary, or are there any zones of absolute non-coincidence and, perhaps, confrontation between the national and the Soviet? The study of the texts has demonstrated the stable patterns that reflect the entrenched national picture of the Kazakhstani world: the traditional cultural relationships between people, a customary and ritualized way of life, manners and customs, the strength of beliefs, and mythology. The patterns that demonstrate the Soviet features imposed on the life of Kazakhstan, as a rule, indicate only a partial acceptance of such novelty and rejection of what was imposed and harmed the republic (e. g. the Semipalatinsk tests polygon). The contrast and compare between the patterns of city and village / aul that has little in common with the contrast between the city and the countryside in the prose of Russian village writers, bears a special context load. The analysis of the stories showed that it is precisely the Soviet city that could be found in any republic of the ex-USSR, whereas any Kazakhstan’s countryside is precisely the Kazakh aul with its established unique rituals and norms of existence. As a result of the texts study, it has been concluded that these stories reflect a real trend in the development of sovereign Kazakhstan: to do away with the Soviet order and return to traditional values.

The contours and segments of objects in digital images have many important applications. Contour extractions of gray images can be converted into contour extractions of binary images. This paper presents a novel contour-extraction algorithm for binary images and provides a deduction theory for this algorithm. First, we discuss the method used to construct convex hulls of regions of objects. The contour of an object evolves from a convex polygon until the exact boundary is obtained. Second, the projection methods from lines to objects are studied, in which, a polygon iteration method is presented using linear projection. The result of the iteration is the contour of the object region. Lastly, addressing the problem that direct projections probably cannot find correct projection points, an effective discrete ray-projection method is presented. Comparisons with other contour deformation algorithms show that the algorithm in the present paper is very robust with respect to the shapes of the object regions. Numerical tests show that time consumption is primarily concentrated on convex hull computation, and the implementation efficiency of the program can satisfy the requirement of interactive operations.

The purpose of the study was to determine the connection between physical fitness and the results on the gymnastics polygon in the seventh and eighth grade elementary school students. Additionally, it was necessary to determine the differences in the observed variables in relation to the grade, separately for each gender. Materials and methods. A total of 128 students from three elementary schools (64 male and 64 female students), 13 and 14 years old, participated in the testing. Five physical fitness tests were used (modified agility "T" test (MAT), Illinois agility run test, 10x5 shuttle run test, standing balance test and 2-minute step in place test), and a specially designed gymnastics polygon was used to assess the level of adoption of technical elements from artistic gymnastics. Results. A statistically significant correlation was recorded between all observed parameters with different levels, from moderate to strong correlations, both in relation to the grade, as well as in relation to the gender of the students. It was also determined that in boys, there are differences in only one test (MAT) in favor of the eighth graders, while in girls, there was a difference in three tests (MAT; 10x5 shuttle test; 2-minute step in place test) in favor of the eighth graders. Conclusions. So it can be concluded that there is a strong mutual connection between physical fitness and sports-specific skills, which are presented in this paper by means of the technical elements of artistic gymnastics.

ABSTRACT Existing soil maps (legacy data) associated with digital mapping techniques are alternatives to obtain information at lower costs, however, tests are required to do it more efficiently. This study had as objectives to compare different methods to extract information from detailed scale soil maps using decision trees for mapping soil classes at two watersheds in Minas Gerais, validate these maps in the field and use the best method to extrapolate information to larger areas, also validating these maps of larger areas. Detailed soil maps of Vista Bela creek (VBW) and Marcela creek (MCW) watersheds were used as source of information. Seven methods to extract information from maps were compared: the whole polygon, eliminating 20 and 40 m from the polygon boundaries, and with buffers around the sampled points with radii of 25 m, 50 m, 75 m, and 100 m. The Classification and Regression Trees (CART) algorithm was employed to create decision trees and enable creation of soil maps. Accuracy was assessed through overall accuracy and kappa index. The best method was used to extrapolate information to larger areas and maps were validated. The best methods for VCW and MCW were, respectively, eliminating 20 m from polygon edges and buffer of 25 m of radii from points. Maps for larger areas were obtained using these methods. Removing uncertainty areas from legacy soil maps contribute to better modeling and prediction of soil classes. Information generated in this work allowed for validated extrapolation of soil maps for regions surrounding the watersheds.

ABSTRACTMud polygons forming in a valley train deposit in Teleki Valley on Mount Kenya were studied with respect to their physical, mineralogical, chemical and biological characteristics. Developing in fine-grained alluvium of postglacial age, those polygonal systems are composed of numerous, and nearly isomorphous units, that appear close to existing drainages in areas stripped of vegetation cover. Stream erosion and animal activity (particularly rodents and Mount Kenya hyrax, e.g. cony) appear to be primarily responsible for the loss of plant cover. Field tests show that periodic wetting and drying results in closure and reopening of polygonal cracks; freeze thaw activity was not observed to assist in developing polygonal ground shape. Subsequent laboratory tests on several samples confirm that the lack of expandable clay minerals might inhibit wetting-drying activity in individual polygon samples.

Physical fitness is an important health indicator and component of physical literacy. Therefore, monitoring youth fitness performance is crucial for identifying potential health risks and tracking physical literacy development. Over the years, many fitness test batteries have been developed while different protocols for footwear have been used in fitness testing. The comparison of fitness results performed in different footwear could therefore be questioned. Thus, the purpose of this study was to examine the differences between barefoot and shod performance of selected motor tests in adolescents. Eighty-six adolescents aged between 14 and 16 years performed standing long jump, 20-m shuttle run, and polygon backwards in both footwear conditions. A strong correlation (r=0.83-0.95) was noted between both performances. No significant differences between barefoot and shod performance in the standing long jump and the backward obstacle course test were found, while significant differences were noted in the 20-m shuttle run. In this test, both, boys and girls performed better in shod conditions. Interestingly, there were no significant differences in performance of all tests among those who are habitually barefoot and others. From practical perspective, this study demonstrated that researchers could compare scores of samples in barefoot and shod performance of standing long jump and backward obstacle course tests. However, when physical teachers compare individual scores over the years, this should be made under the same footwear conditions, as differences in test conditions can provide a distorted picture of motor development.

In this paper we consider the problem of distributing empty freight cars in a railway polygon. We show how the process can be improved using an optimization model. The optimization model can be characterized as a combination of minimum-cost flow problem with vehicle routing problem. In general, problem of empty railroad car distribution between stations and definition of way-freight train route is presented as integer combinatorial optimization problem. Computational tests show that the model can be solved in acceptable time for real size problems, and indicate that the model generates distribution plans that can improve the quality of the planning process.

The aim of this study is to determine there is a statistically significant difference in motor ability indicators in children of early school age before and after the defined experimental process. The total number of subjects is 40 and the subjects was divided into two subsamples: a subsample of boys (n = 20) with an average age of 6.20 ± 0.34 years and a subsample of a girls (n = 20) with an average age of 6.16 ± 0.62 years. All subjects were participants in the program of the sports school of the children fitness centre Smart Gym from Podgorica. Subsamples were subjected to an experimental process lasting 8 weeks. Immediately before and after the experimental process, motor abilities were measured using the following 10 tests: 5m sprint, 10m sprint, standing long jump, polygon backwards, bent arm hang, sit and reach, climbing and descending, stork balance stand test, sit ups, and throw and catch test. The results of the study show that the experimental process was successful in improving the polygon backwards, forward deep bend and throw and catch test in boys and stork balance stand test, sit ups and throw and catch test in girls. Such a program could improve the working methodology in all sport schools throughout Montenegro.

Abstract Even though the frontal collisions occur in a much larger percentage than the lateral collisions, the lateral collisions consequences can be much more serious than the frontal collisions. This paper is meant to be a study on the importance of crush energy, which determines the mechanism that produces the severity of injuries. Using Newton laws of mechanics, we can discuss about the conservation of energy and linear momentum law which determine the impact force, speed and deformation. After, we compared the obtained data from the laboratory virtual crash tests with the determined values from the polygon experimental tests. Analytical techniques that determine the occupant and vehicle behaviour from this stage allow determining the mechanism that produces the damages and biomedical parameters, which are representative and correspond to the real applications from the practice investigation of the traffic events. The information is extremely useful to expert investigators who activates in the field of traffic events investigation and reconstruction.

The present study is based on the paraclinical and functional evaluation of a sample of 66 subjects with ischaemic stroke, to monitor the evolution of their functional parameters. The tests concerning the variation of barycentre speed within the support polygon and the curve length were conducted using the GPS 400 Posturograph, which provided us with information related to the balance of the subjects in an orthostatic stance with eyes open, with eyes closed, looking to the right, looking to the left, head tilted to the right, head tilted to the left, head in extension. Our findings highlight the balance re-education capacity of the subjects with ischaemic stroke through individualised physical therapy programs.

Full textAbstract:
Remnant midwestern oak savannas in the USA have been altered by fire suppression and the encroachment of woody evergreen trees and shrubs. The Gus Engeling Wildlife Management Area (GEWMA) near Palestine, Texas represents a relatively intact southern example of thickening and evergreen encroachment in oak savannas. In this study, 18 images from the CHRIS/PROBA (Compact High-Resolution Imaging Spectrometer/Project for On-Board Autonomy) sensor were acquired between June 2009 and October 2010 and used to explore variation in canopy dynamics among deciduous and evergreen trees and shrubs, and savanna grassland in seasonal leaf-on and leaf-off conditions. Nadir CHRIS images from the 11 useable dates were processed to surface reflectance and a selection of vegetation indices (VIs) sensitive to pigments, photosynthetic efficiency, and canopy water content were calculated. An analysis of temporal VI phenology was undertaken using a fishnet polygon at 90 m resolution incorporating tree densities from a classified aerial photo and soil type polygons. The results showed that the major differences in spectral phenology were associated with deciduous tree density, the density of evergreen trees and shrubs—especially during deciduous leaf-off periods—broad vegetation types, and soil type interactions with elevation. The VIs were sensitive to high densities of evergreens during the leaf-off period and indicative of a photosynthetic advantage over deciduous trees. The largest differences in VI profiles were associated with high and low tree density, and soil types with the lowest and highest available soil water. The study showed how time series of hyperspectral data could be used to monitor the relative abundance and vigor of desirable and less desirable species in conservation lands.

AbstractAlthough the red-bellied piranha, Pygocentrus nattereri is widely portrayed as a pack-hunting predator virtually nothing is known about its shoaling behaviour. Using fish collected in the flooded forest of the Brazilian Amazon, we conducted a range of choice tests to determine whether individual piranhas make non-random shoaling decisions. These revealed that partner size had a significant impact on shoaling preferences. Piranha shoals were size structured with large, sexually mature, individuals occupying the central zone (defined as within the polygon connecting fish at the edge of the shoal). Small, non-reproductive individuals showed greater motivation to feed. Fish did not discriminate between size-matched individuals from the same and different locality and we found no evidence of intraspecific aggression, despite the piranha's reputation for cannibalism.
