On the sides of a right-angled isosceles triangle, squares external to this triangle are built. The task is to construct a straight line on a plane that divides a figure consisting of these three squares into two equal-sized (that is, equal area) figures. Some parameters determined by this line are calculated, in particular, the areas of parts of the original squares in half-planes. The corresponding results are illustrated by various drawings, tables and graphs.

Full textAbstract:
In this paper are considered planar point sets generated by linear conditions, which are realized in rectangular or Manhattan metric. Linear conditions are those expressed by the finite sum of the products of distances by numerical coefficients. Finite sets of points and lines are considered as figures defining linear conditions. It has been shown that linear conditions can be defined relative to other planar figures: lines, polygons, etc. The design solutions of the following general geometric problem are considered: for a finite set of figures (points, line segments, polygons...) specified on a plane with a rectangular metric, which are in a common position, it is necessary to construct sets that satisfy any linear condition. The problems in which the given sets are point and segment ones have been considered in detail, and linear conditions are represented as a sum or as relations of distances. It is proved that solution result can be isolated points, broken lines, and areas on the plane. Sets of broken lines satisfying the given conditions form families of isolines for the given condition. An algorithm for building isoline families is presented. The algorithm is based on the Hanan lattice construction and the isolines behavior in each node and each sub-region of the lattice. For isoline families defined by conditions for relation of distances, some of their properties allowing accelerate their construction process are proved. As an example for application of the described theory, the problem of plane partition into regions corresponding to a given set of points, lines and other figures is considered. The problem is generalized problem of Voronoi diagram construction, and considered in general formulation. It means the next: 1) the problem is considered in rectangular metric; 2) all given points may be integrated in various figures – separate points, line segments, triangles, quadrangles etc.; 3) the Voronoi diagram’s property of proximity is changed for property of proportionality. Have been represented examples for plane partition into regions, determined by two-point sets.

Full textAbstract:
This paper aims at an efficient treatment of spatial data using qualitative representation. We propose a new framework called PLCA, which provides a symbolic representation for the figure in a two-dimensional plane, focusing on the connections between regions. It is based on four simple objects: points(P), lines(L), circuits(C) and areas(A). The entire figure is represented as a combination of these objects. Pairs of areas, circuits or lines never cross. The simple, clear data structure based on objects makes the system feasible and easy to implement. A PLCA expression can be subject to topological reasoning such as judging the connection patterns of areas. We define the operations of area integration and area division on a PLCA expression. These operations preserve the consistency of the expression, and correspond to real actions on the figures. We can add attributes to each object, such as the properties that hold on an area or that an object represents, and make an attributed PLCA. The operations of area integration/division on an attributed PLCA correspond to the alteration of the classification level of objects, and semantic spatial reasoning can be performed on an attributed PLCA.

Full textAbstract:
Instruction in the concept of area begins in elementary school and continues through college calculus. Students learn to apply formulas for certain plane figures and later, integration techniques. For figures that are not “nice” shapes or for “irregular” functions, students are taught approximation techniques, which range from counting squares in middle school to trigonometric approximations in high school and various methods of calculus. The purpose of this article is to offer the use of the Monte Carlo procedure on the microcomputer as an alternative tool for approximating areas. One of the introductory applications of the technique is to find the area of a circle, which permits us to approximate pi.

In this paper we present convergence concepts applications of numerical and functions sequences to a geometric problem which raised from an analysis using GeoGebra. This question involves the traces’s family of plane curves behavior, whose initial trace of the curve is given by a circle of radius k and the whose others, intuitively, approach to a square with side measuring 2k. A proof of this convergence is done, as well a demonstration that the areas bounded by the traces of the curves and their lengths converge, respectively, to the area and length of the boundary square. We also present a brief historical setting of convergence concepts and the ideas of infinity behind these concepts. In order to be developed to graduation level, this paper goes some way meet what historically was done to determine properties of curved figures through approximations by rectilinear figures.

Full textAbstract:
Austenite grains that underwent the f.c.c. to b.c.c. (or b.c.t.) transformation are typically composed of 24 Kurdjumov–Sachs variants that can be categorized by three axes of Bain transformations; thus, a complete transformation generally displays 3-fold symmetry in (001) pole figures. In the present work, crystallographic symmetry in 42CrMo4 steel austempered below martensite start temperature was investigated with the help of the orientation distribution function (ODF) analysis based on the FEG-SEM/EBSD technique. It is shown that, upon phase transformations, the specimens contained 6-fold symmetry in all (001), (011), and (111) pole figures of an ODF. The ODF analysis, verified by theoretical modeling, showed that under plane-strain conditions cracks prefer to propagate through areas strongly offset by the high symmetry. The origin of high symmetry was investigated, and the mechanism of the symmetry breakdown was explained.

Abstract In this paper I argue that sociology was a key discipline in producing relevant knowledge for managing and reimagining the socialist economic development in Romania. It played a central role in placing economic development at the subnational level, since much of the everyday economics unfolded at the level of the regions, which formed around the emerging cities. I analyse the birth of the ‘urban area’, an academic concept and a policy tool, as it was developed by Miron Constantinescu and his associate Henry H. Stahl. This was the main device that shifted economic growth to the subnational level and allowed the planners to regulate the economy as a set of inter-connected production chains. Sociology was disbanded as an academic discipline in 1948; nonetheless, through the figure of Miron Constantinescu, a key member of the Political Bureau between 1945-1957, it remained a central producer of knowledge through complex institutional arrangements, put in place in the 1950s. These institutions employed sociological figures from the inter-war sociological establishment. Their methodological skills and theoretical endeavours were put to work in applied research. I argue that some strategic developmentalist policies in socialist Romania were strongly shaped by the reworking in Marxist terms of certain key ideas of the Gustian school of a ‘sociology of the nation’.

The initial orientation has split into two equally strong symmetric orientations: (112)[111¯] and (112)[1¯1¯1]. Areas of identical orientation were band shaped and were called deformation bands. Up to 60% reduction, deformation occurs by slip on one plane (one from two possible) in two directions. This leads to the appearance of deformation bands with transition bands between them. Due to such deformation the initial orientation rotates around transverse direction towards the end-orientation {112}〈111〉. Due to rotation of the crystallographic lattice with deformation, the Taylor factor M changes as well, and it causes the activation of two not coplanar slip systems which stabilize the end-orientations {112}〈111〉. Such a sequence of the slip systems activation was concluded from the agreement of the calculated and experimental pole figures. The electron microscopy investigations showed that first shear bands formed due to the activation of these new slip systems.

Hamlin Garland, an influential American writer, puts forward his literary theory—Veritism. His collection of short stories-Main-Travelled Roads insists on describing the real situation of Midwest and West rural areas by using “Veritism”, as well as expresses the great humanistic concern and deep thinking about the changes that had taken place between urban and rural areas. By analyzing the figures and plots of Main-Travelled Roads, this paper will reveal humanism and classical sensibility, happy endings, and aesthetic value in it, and let readers understand the theme of the short stories thoroughly, and appreciate the Veritism comprehensively.

The geometry study is important because it allows people to think more logically and opens the mind to a new level of thinking and reasoning skills. However, for various reasons, this area of mathematics is little explored in the classes of basic education. In this sense, it woke up the interest in developing studies that could be interesting and relevant to the geometry teaching in basic education, in order to collaborate with the classes. And the theme was the area of plane figures and equidecomposable polygons. Thus, the main objective of this work is the proposal of problems that can be solved with the decomposition of polygons, as suggested activities for the general education teacher can apply them in their practice. The methodology used was the development of bibliographic research relating to fundamental concepts of geometry, as well as equidecomposable polygons, followed the presentation of activities involving area of plane figures and decomposition of polygons. It is expected this work, assisting the work of teachers of basic education and thus contribute to the improvement of geometry teaching in basic school.

COORDENAÇÃO DE APERFEIÇOAMENTO DO PESSOAL DE ENSINO SUPERIORO uso cada vez mais corrente de métodos heurístico tem permitido contribuir para a automação e otimização de inúmeros processos industriais complexos. Um dos processos que vem sendo beneficiado é o corte de roupas na indústria do vestuário, onde o encaixe de moldes deve ser feito de forma a minimizar o desperdício de tecido. Este trabalho visa a dar uma contribuição ao problema geral de encaixe de figuras planas irregulares. Assim, busca-se resolver este problema através do uso de regras heurísticas implementadas num algoritmo computacional. Como ponto principal, o apresenta uma sistemática de construção de alternativas de encaixe, em forma de uma árvore, facilitando a busca de um encaixe solução, de alto rendimento, entre as praticamente infinitas possibilidades. A viabilização do algoritmo de encaixe é alcançada através de duas técnicas de posicionamento dos moldes que previnem sua superposição. As vantagens das duas técnicas são combinadas para melhor proveito do algoritmo. Nas conclusões são discutidas as dificuldades encontradas e formulados novos caminhos para a investigação.
The increasing use of heuristical methods has advanced the frontier of application of optimization and automatization techniques in complex industrial processes. One emerging utilization for these methods in the pattern nesting process in the garment industry. The aim is to nest the pattern in such a way as to minimize the waste of fabric. The present work aims to contribute to the optimal nesting of general planes figures. The methods which will be discussed, employ heustical rules implemented thorough computacional algorithms. The focal point of the work is a methodology of obtaining a sequence of partial and complete nesting from which the best one can be selected. The computacional algorithm embodies two distinct methods for the placement of the figures on the nesting plane avoiding superposition. Both methods are used in such way that the resulting algorithm profits from their advantages. Present diffuclties and future trends are outlined in the conclusions.

Previous issue date: 2011-10-28This research treats the practice of the argumentation as teaching method, focusing the concepts of area perimeter of plane figures. Studies in national and international levels have already broached the subject, many times using the practice of the argumentation as method, not proposing, however, ways that demonstrate the functionality of that method. So this work answers the following question: in what measure the practice of the argumentation can present itself as method that contributes to the comprehension of concepts in mathematics taking as reference the case of the area and the perimeter of plane figures? To answer our question, we propose a didactic sequence modeled and analyzed with basis in the phases that compose the argumentative process, according to Toulmin (1996). The methodology of the study have been supported in Didactic Engineering purposes, the intervention have been effectuated with pupils at the fifth grade in Ensino Fundamental (students aged 10-11), using two argumentative institutions: the classroom and the informatics laboratory where we used the Geogebra software. The theoretical foundation have been based in speculative reflections by Toulmin (1996), in argumentative classification by Pedemonte (2002) and Cabassut (2005) and in the idea of argumentative convergence by Perelman and Olbrechts-Tyteca (2005). The analysis of the activities have evidenced that the practice of the argumentation contribute to the comprehension of the concepts of area and perimeter of plane figures, habilitating this practice as teaching method. The argumentative competences acquired by the pupils through the interactions with their classmates and the researchers about the subject allowed them have more autonomy to communicate and defend their ideas, respecting the opinion of the other classmates during the discussions, pay attention to the functionality and the possible validity of their argument, besides to learn specific symbols and language of mathematics
Esta pesquisa trata da prática da argumentação como método de ensino, focalizando os conceitos de área e perímetro de figuras planas. Estudos em níveis nacionais e internacionais já abordaram o assunto, muitas das vezes utilizando a prática da argumentação como método, sem, no entanto, propor caminhos que demonstrassem a funcionalidade dessa abordagem. Assim, este trabalho responde à seguinte questão: em que medida a prática da argumentação pode se apresentar como método que favoreça a compreensão de conceitos em matemática, tomando como referência o caso da área e perímetro de figuras planas? Como resposta, propomos uma sequência didática modelada e analisada com base nas fases que compõem o processo argumentativo segundo Toulmin (1996). A metodologia do estudo apoiou-se em pressupostos da Engenharia Didática e a intervenção foi efetivada com alunos do quinto ano do Ensino Fundamental (alunos de 10 a 11 anos), utilizando duas instituições argumentativas: a sala de aula e o laboratório de informática, no qual usamos o software Geogebra. A fundamentação teórica baseou-se nas reflexões teóricas de Toulmin (1996), na classificação de argumentos de Pedemonte (2002) e Cabassut (2005) e na idéia de convergência argumentativa de Perelman e Olbrechts-Tyteca (2005). As análises das atividades evidenciaram que a prática da argumentação favoreceu a compreensão dos conceitos de área e perímetro de figuras planas, habilitando essa prática como método de ensino. As competências argumentativas adquiridas pelos discentes, a partir das interações com colegas e pesquisador sobre o assunto em questão, possibilitaram- lhes ter mais autonomia para comunicar e defender suas ideias, respeitando a opinião do colega no decorrer das discussões, ficar atentos à funcionalidade e à validade ou não de seu argumento, além de apreender símbolos e linguagem específicos da matemática

This work is the result of a qualitative and quantitative analysis of the problems encountered in the teaching of plane figures in young and adult education and, even as a present activity in day-to-day lives, it is still a problem. This theme was chosen because of the student?s desires to learn that content, enabling to search where is the origin of the various difficulties encountered by them in calculating areas of plane figures and to get applied in their daily lives. The choice of this teaching modality comes from the challenge of how to work this content with a very heterogeneous group, both in age and in the motivation that led them to attend the classrooms of young and adult education. This fact causes a significant change in the methodology used by the professor in relation to the same applied in regular education. To understand all this process it is necessary to know a little of young and adult education in Brazil, its normative aspects and the historical importance of knowing how to calculate areas of flat figures. Through a questionnaire, we identified the young and adult education professor's profile, how this type of education is administered by the government and how professionals deal with such different student profiles. With this information, together with the analyzes of the questions answered by the students, we conclude that the difficulty of assigning correctly the units of area and length measurements is due to the difficulty of the student to relate the mathematical content learned in school to their daily lives. In some of the issues applied to students we had to allow the use of the calculator due to the difficulty that students have to perform at least one of the four arithmetic operations
Esse trabalho ? o resultado de uma an?lise qualitativa e quantitativa sobre os problemas encontrados no ensino de ?rea de figuras planas na EJA e que, mesmo sendo uma atividade presente no dia-a-dia deles, ainda ? um problema. Esse tema foi escolhido devido aos anseios dos alunos em aprender esse conte?do, possibilitando assim, pesquisar onde est? a origem das diversas dificuldades encontradas por eles em calcular ?reas de figuras planas e conseguirem aplicar em seus cotidianos. A escolha dessa modalidade de ensino surge do desafio de como trabalhar esse conte?do com um grupo muito heterog?neo, tanto na faixa et?ria quanto na motiva??o que os levaram a frequentar as salas de aula da EJA. Este fato provoca uma mudan?a significativa na metodologia aplicada pelo professor em rela??o ? mesma metodologia aplicada no ensino regular. Para entender todo esse processo faz-se necess?rio conhecer um pouco da EJA no Brasil, seus aspectos normativos e a import?ncia hist?rica de saber calcular ?reas de figuras planas. Por meio de um question?rio, identificamos o perfil do professor da EJA, como essa modalidade de ensino ? administrada pelo poder p?blico e como os profissionais lidam com perfis t?o diferentes de alunos. De posse dessas informa??es, somadas as an?lises das quest?es respondidas pelos alunos, conclu?mos que a dificuldade de atribuir de forma correta as unidades de medidas de ?rea e de comprimento devem-se ? dificuldade do aluno em relacionar o conte?do matem?tico aprendido na escola ao seu cotidiano. Em algumas das quest?es aplicadas aos alunos tivemos que permitir o uso da calculadora devido ? dificuldade que os alunos possuem em realizar pelo menos uma das quatro opera??es da aritm?tica.

In this work we will make a brief study on the calculation of areas and lengths highlighting how these can be presented in high school, then we will use the di erential and integral calculus to extend the calculations of areas and lengths. Therefore, this study some of the developments in the history of calculus concepts and their "basic", beyond the definitions of areas, lengths, and applications of limit, derivative and integral. We emphasize that the provision contained in this learning material is not in a single textbook adopted in schools.
Neste trabalho faremos um breve estudo a respeito do cálculo de áreas e comprimentos destacando como esses podem ser apresentados no ensino médio, em seguida faremos uso do cálculo diferencial e integral para estendermos os cálculos de áreas e comprimentos. Para isso, estudaremos um pouco da evolução do cálculo na história e seus conceitos "básicos", além das definições de áreas, comprimentos, e aplicações do limite, derivada e integral. Ressaltamos que a disposição contida neste material didático não se encontra em um único livro didático adotado nas escolas.

nÃo hÃEste trabalho tem como objetivo principal inserir, no Ensino MÃdio, a ideia intuitiva da Integral Definida, o cÃlculo de Ãreas abaixo do grÃfico de funÃÃes positivas, limitadas pelo eixo das abscissas e por retas verticais, ou atà mesmo entre funÃÃes positivas em um intervalo determinado pelo domÃnio das mesmas, por exemplo. Para facilitar o entendimento dessas ideias, aliado ao estudo de funÃÃes, pode-se fazer o uso de um recurso computacional como o Geogebra, software utilizado como ferramenta de apoio a aprendizagem nas atividades sugeridas nesse trabalho. As atividades aqui propostas destinam-se a alunos do ensino mÃdio. Destaca-se a importÃncia da introduÃÃo dessas ideias por estimular a construÃÃo de conhecimentos mais sÃlidos sobre o comportamento de funÃÃes. Acredita-se que, assim, a longo prazo, os alunos que ingressarem no Ensino Superior nas disciplinas de CÃlculo terÃo condiÃÃes melhores de compreender os conceitos necessÃrios e, assim, os Ãndices de reprovaÃÃo nessas disciplinas serÃo reduzidos. O trabalho a seguir apresenta uma proposta de atividades sobre o ensino desses tÃpicos com auxÃlio do software GeoGebra. Verificou-se que à possÃvel abrir os horizontes no Ãmbito do ensino e aprendizagem de MatemÃtica no Ensino MÃdio, com as ideias intuitivas de CÃlculo, fazendo o uso de ferramentas diversas, como a utilizaÃÃo de tecnologias apropriadas e que à possÃvel, inclusive, proporcionar aos estudantes novas tÃcnicas de ensino que favoreÃam a aprendizagem desses e demais conceitos matemÃticos.
This work aims to incorporate in high school, the intuitive idea of the Definite Integral, calculation of areas below the positive functions, bounded by the x-axis and vertical lines, or even between positive graph functions in a certain range the area of the same, for example. To facilitate the understanding of these ideas, combined with the study of functions, you can make use of a computational resource such as Geogebra, software used to support learning activities suggested in this work tool. The activities proposed here are intended for high school students. Highlights the importance of introducing these ideas to stimulate the construction of more accurate information on the behavior of functions. It is believed that thus the term, students who enter higher education in the disciplines of calculation will be better able to understand the necessary and thus the failure rates in these disciplines will be reduced concepts. The following work presents a proposal of activities for teaching these topics with the help of GeoGebra software. It was found that you can open the horizons within the teaching and learning of Mathematics in Secondary Education, with intuitive ideas of Calculus, making the use of various tools such as the use of appropriate technologies and that is even possible to provide students new teaching techniques that encourage learning these and other mathematical concepts.

Full textAbstract:
L'objet de notre travail est l'édition critique, la traduction française et l'analyse mathématique du Liber mensurationum d'Abu Bakr, du Liber Saydi Abuothmi, du Liber Aderameti et du De superficierum divisionibus liber de Muhammad al-Baghdadi. Ces quatre textes de la tradition arabe traitent de deux chapitres de géométrie pratique: le mesurage et le découpage. Le mesurage a pour objet la détermination de grandeurs inconnues (longueurs, aires, volumes) à partir de grandeurs données. Le découpage consiste à diviser une figure géométrique en plusieurs parties selon des propriétés et des contraintes fixées a priori. Notre travail prend en compte certaines traditions mathématiques antérieures - mésopotamienne, grecque, latine de l'Antiquité tardive - en décrivant leurs activités de mesurage et de découpage. Nous complétons cette description avec une présentation des pratiques de l'Orient et de l'Occident musulmans. Ainsi, nous mettons en évidence certains éléments caractéristiques des pratiques de l'Occident musulman. Ceux-ci suggèreraient l'existence d'une tradition du mesurage et du découpage propre à cette région. Enfin, le corpus que nous présentons est un vecteur de la diffusion des pratiques de géométrie de la tradition arabe au monde latin. En effet, les quatre textes sont des traductions arabo-Iatines qui semblent avoir été réalisées en Andalus aux alentours du 12e siècle. À ce titre, leurs analyses nous permettent d'étudier un aspect de l'appropriation de la science arabe par les LatinsThe object of our work is the critical edition, the French translation and the mathematical analysis of the Liber mensurationum of Abu Bakr, of the Liber Saydi Abuothmi, of the Liber Aderameti and of the De superficierum divisionibus liber of Mulhammad al-Baghdadï. These four texts of the Arabian tradition are about two chapters of practical geometry : the measurement and the division of figures. The measurement has for object the determination of unknown quantities (lengths, areas, volumes) from quantities data. The division of figures consists in dividing a geometric figures in several parts according to properties and constraints fixed a priori. Our work takes in account sorne previous mathematical traditions - mesopotamian one, Greek and Latin of the late Antiquity - describing their activities of measurement and division of figures. We complete this description with a presentation of the practices of the muslim Orient and Occident. Thus, we put in evidence sorne characteristic elements of the practices of the Muslim west. These would suggest the existence of a tradition of the measurement and the division of figures to this region. Finally, the corpus that we present is a vector of the diffusion of the practices of geometry of the Arabian tradition in the Latin world. Indeed, the four texts are arabo-Latin translations that seem have been achieved in Andalus around the 12th century. Their analyses allow us to study an aspect of the appropriation of the Arabian science by the Latin

Kuffner, Emily. Fictions of Containment in the Spanish Female Picaresque. NL Amsterdam: Amsterdam University Press, 2019. http://dx.doi.org/10.5117/9789462986800.
Full textAbstract:
This study examines the interdependence of gender, sexuality and space in the early modern period, which saw the inception of architecture as a discipline and gave rise to the first custodial institutions for women, including convents for reformed prostitutes. Meanwhile, conduct manuals established prescriptive mandates for female use of space, concentrating especially on the liminal spaces of the home. This work traces literary prostitution in the Spanish Mediterranean through the sixteenth and seventeenth centuries, from the rise of courtesan culture in several key areas through the shift from tolerance of prostitution toward repression. Kuffner’s analysis pairs canonical and noncanonical works of fiction with didactic writing, architectural treatises, and legal mandates, tying the literary practice of prostitution to increasing control over female sexuality during the Counter Reformation. By tracing erotic negotiations in the female picaresque novel from its origins through later manifestations, she demonstrates that even as societal attitudes towards prostitution shifted dramatically, a countervailing tendency to view prostitution as an essential part of the social fabric undergirds many representations of literary prostitutes. Kuffner’s analysis reveals that the semblance of domestic enclosure figures as a primary erotic strategy in female picaresque fiction, allowing readers to assess the variety of strategies used by authors to comment on the relationship between unruly female sexuality and social order.

AbstractThis chapter invites appreciation of the development of an ethnomathematical perspective on the question of the idea of multiplication. The teaching approach described here is grounded on miniprojects that integrate diverse areas of knowledge. It reveals a style of work being performed in the Waldorf Schools of São Paulo, Brazil, where the concept of multiplication is constructed together with the geometry of plane figures through the elaboration of mathematical thinking together with figures mounted on a circular wooden table. The sequence highlights ideas of context connected to the use of cellular phones by the students to introduce the concept of proportionality by taking photos of their bodies and faces, and then using them to study Leonardo da Vinci’s Vitruvian Man.

To connect a pipe spool between existing pipes with high accuracy for power plant constructions, a calculation approach which figures out appropriate cutting positions and angles of extra length areas of the spool has been developed. In this approach, center positions and axes of end surfaces are modeled numerically based on three-dimensional measurement of each pipe, and the appropriate cutting surfaces are calculated by geometric analysis of the models with considering for ease of cutting work at the construction site. This paper described a modeling method of pipes, a calculation algorithm of the proper cutting surfaces of the spool, and a verification result of the calculation.

Full textAbstract:
In the spring of 2019, the Montana State University (MSU) Library embarked on a large-scale inventory project that involved weeding and moving portions of their collection to an offsite storage facility within six months in order to create more student study space in the Library. The department primarily responsible for leading the project, Collections Access & Technical Services, the result of two departments merging, was also simultaneously navigating their new structure and a remodel of their workspace thus adding further challenges to the project. This poster session demonstrated how MSU Library approached and completed this project by advocating to their Library Administration for additional resources, including hiring a project manager and third-party companies to assist with the inventory and moving of the collection. It also discussed the types of work groups formed to identify new workflows (i.e., retrieval of offsite items) and modify existing ones, involving student employees in the project, and internal and external collaborations that took place. Additionally, presenters shared strategies used to communicate to their campus community, and the impact this project has had on our patrons. They also included statistics that were gathered during the project including deselection figures, the number of materials that did not have barcodes and were not accounted for in the Library’s catalog and discovery layer (Ex Libris’ Alma and Primo), and what subject areas currently remain in the main library building.

Full textAbstract:
The Annual Report on Migration and Asylum 2016 provides an overview of trends, policy developments and significant debates in the area of asylum and migration during 2016 in Ireland. Some important developments in 2016 included: The International Protection Act 2015 was commenced throughout 2016. The single application procedure under the Act came into operation from 31 December 2016. The International Protection Office (IPO) replaced the Office of the Refugee Applications Commissioner (ORAC) from 31 December 2016. The first instance appeals body, the International Protection Appeals Tribunal (IPAT), replacing the Refugee Appeals Tribunal (RAT), was established on 31 December 2016. An online appointments system for all registrations at the Registration Office in Dublin was introduced. An electronic Employment Permits Online System (EPOS) was introduced. The Irish Short Stay Visa Waiver Programme was extended for a further five years to October 2021. The Second National Action Plan to Prevent and Combat Human Trafficking was published. 2016 was the first full year of implementation of the Irish Refugee Protection Programme (IRPP). A total of 240 persons were relocated to Ireland from Greece under the relocation strand of the programme and 356 persons were resettled to Ireland. Following an Oireachtas motion, the Government agreed to allocate up to 200 places to unaccompanied minors who had been living in the former migrant camp in Calais and who expressed a wish to come to Ireland. This figure is included in the overall total under the IRPP. Ireland and Jordan were appointed as co-facilitators in February 2016 to conduct preparatory negotiations for the UN high level Summit for Refugees and Migrants. The New York Declaration, of September 2016, sets out plans to start negotiations for a global compact for safe, orderly and regular migration and a global compact for refugees to be adopted in 2018. Key figures for 2016: There were approximately 115,000 non-EEA nationals with permission to remain in Ireland in 2016 compared to 114,000 at the end of 2015. Net inward migration for non-EU nationals is estimated to be 15,700. The number of newly arriving immigrants increased year-on-year to 84,600 at April 2017 from 82,300 at end April 2016. Non-EU nationals represented 34.8 per cent of this total at end April 2017. A total of 104,572 visas, both long stay and short stay, were issued in 2016. Approximately 4,127 persons were refused entry to Ireland at the external borders. Of these, 396 were subsequently admitted to pursue a protection application. 428 persons were returned from Ireland as part of forced return measures, with 187 availing of voluntary return, of which 143 were assisted by the International Organization for Migration Assisted Voluntary Return Programme. There were 532 permissions of leave to remain granted under section 3 of the Immigration Act 1999 during 2016. A total of 2,244 applications for refugee status were received in 2016, a drop of 32 per cent from 2015 (3,276). 641 subsidiary protection cases were processed and 431 new applications for subsidiary protection were submitted. 358 applications for family reunification in respect of recognised refugees were received. A total of 95 alleged trafficking victims were identified, compared with 78 in 2015.

Yatsymirska, Mariya. SOCIAL EXPRESSION IN MULTIMEDIA TEXTS. Ivan Franko National University of Lviv, February 2021. http://dx.doi.org/10.30970/vjo.2021.49.11072.
Full textAbstract:
The article investigates functional techniques of extralinguistic expression in multimedia texts; the effectiveness of figurative expressions as a reaction to modern events in Ukraine and their influence on the formation of public opinion is shown. Publications of journalists, broadcasts of media resonators, experts, public figures, politicians, readers are analyzed. The language of the media plays a key role in shaping the worldview of the young political elite in the first place. The essence of each statement is a focused thought that reacts to events in the world or in one’s own country. The most popular platform for mass information and social interaction is, first of all, network journalism, which is characterized by mobility and unlimited time and space. Authors have complete freedom to express their views in direct language, including their own word formation. Phonetic, lexical, phraseological and stylistic means of speech create expression of the text. A figurative word, a good aphorism or proverb, a paraphrased expression, etc. enhance the effectiveness of a multimedia text. This is especially important for headlines that simultaneously inform and influence the views of millions of readers. Given the wide range of issues raised by the Internet as a medium, research in this area is interdisciplinary. The science of information, combining language and social communication, is at the forefront of global interactions. The Internet is an effective source of knowledge and a forum for free thought. Nonlinear texts (hypertexts) – «branching texts or texts that perform actions on request», multimedia texts change the principles of information collection, storage and dissemination, involving billions of readers in the discussion of global issues. Mastering the word is not an easy task if the author of the publication is not well-read, is not deep in the topic, does not know the psychology of the audience for which he writes. Therefore, the study of media broadcasting is an important component of the professional training of future journalists. The functions of the language of the media require the authors to make the right statements and convincing arguments in the text. Journalism education is not only knowledge of imperative and dispositive norms, but also apodictic ones. In practice, this means that there are rules in media creativity that are based on logical necessity. Apodicticity is the first sign of impressive language on the platform of print or electronic media. Social expression is a combination of creative abilities and linguistic competencies that a journalist realizes in his activity. Creative self-expression is realized in a set of many important factors in the media: the choice of topic, convincing arguments, logical presentation of ideas and deep philological education. Linguistic art, in contrast to painting, music, sculpture, accumulates all visual, auditory, tactile and empathic sensations in a universal sign – the word. The choice of the word for the reproduction of sensory and semantic meanings, its competent use in the appropriate context distinguishes the journalist-intellectual from other participants in forums, round tables, analytical or entertainment programs. Expressive speech in the media is a product of the intellect (ability to think) of all those who write on socio-political or economic topics. In the same plane with him – intelligence (awareness, prudence), the first sign of which (according to Ivan Ogienko) is a good knowledge of the language. Intellectual language is an important means of organizing a journalistic text. It, on the one hand, logically conveys the author’s thoughts, and on the other – encourages the reader to reflect and comprehend what is read. The richness of language is accumulated through continuous self-education and interesting communication. Studies of social expression as an important factor influencing the formation of public consciousness should open up new facets of rational and emotional media broadcasting; to trace physical and psychological reactions to communicative mimicry in the media. Speech mimicry as one of the methods of disguise is increasingly becoming a dangerous factor in manipulating the media. Mimicry is an unprincipled adaptation to the surrounding social conditions; one of the most famous examples of an animal characterized by mimicry (change of protective color and shape) is a chameleon. In a figurative sense, chameleons are called adaptive journalists. Observations show that mimicry in politics is to some extent a kind of game that, like every game, is always conditional and artificial.

National report 2009-2019 - Rural NEET in Croatia. OST Action CA 18213: Rural NEET Youth Network: Modeling the risks underlying rural NEETs social exclusion, December 2020. http://dx.doi.org/10.15847/cisrnyn.nrhr.2020.12.
Full textAbstract:
This report presents the situation of rural Youths Neither in Employment, nor in Education or Training (NEET) in Croatia, aged between 15 and 34 years old, in the period from 2009 until 2019. To achieve this goal, the report utilised indicators of youth population, youth em-ployment and unemployment, education and NEETs distribution. The characterisation of all indicators adopted the degree of urbanisation as a central criteria, enabling comparisons between rural areas, towns and suburbs, cities and the whole country. These analyses are further collapsed into age sub-groups and, when possible, in sex groups for greater detail. The statistical procedures adopted across the different selected dimensions involved des-criptive longitudinal analysis, using figures (e.g., line charts) as well as the calculation of abso-lute and relative changes between 2009 and 2013, 2013 and 2019 and 2009 and 2019. These time ranges were chosen to capture the indicators evolution before and after the economic crisis that hit European countries. All data was extracted from Eurostat public datasets. The analyses show that between 2009 and 2019 rural youth population aged 15 to 24 years has been decreasing in Croatia. Youth unemployment was marked by two distinct periods, one from 2009 to 2013 (with higher rates of youth unemployment) and another from 2013 to 2019 (with the decrease in unemployment rates, with lower unemployment rates in ci-ties and higher in towns and suburbs and rural areas). In the field of education, however, there has been a decrease of the Croatian population with lower levels of education and an increase of the proportion of those with higher educational attainment. Finally, the propor-tion of NEETs in Croatia is higher in rural areas compared to cities and towns and suburbs, revealing territorial inequalities in access to employment and education opportunities.
