De ratione studii: Educational vision of Erasmus of Rotterdam
Full text linkErazem Rotterdamski je kot ena izmed vodilnih osebnosti renesančnega humanizma napisal več vplivnih del s področja vzgoje in izobraževanja. V njih je predstavil svoja stališča o tem, kako je treba zastaviti vzgojo in pouk, da bi bili učenci deležni karseda kakovostne izobrazbe. Ta temelji predvsem na pridobivanju spretnosti v izražanju v klasičnih jezikih ter na branju antične literature, s pomočjo katere se učencu izoblikuje kreposten značaj. V svojih delih Erazem veliko pozornosti posveča pravilni usposobljenosti učitelja, ki mora biti vsestransko razgledan in načitan, pomembna pa je tudi njegova osebnost, saj mu mora biti učenec naklonjen, da učenje poteka čim učinkoviteje. Erazem se v svojih nasvetih zgleduje predvsem po antičnih in renesančnih piscih, saj meni, da je v obdobju srednjega veka kakovost izobraževanja upadla. Pričujoče magistrsko delo vsebuje tudi prevod Erazmovega priročnika za učitelje, naslovljenega O metodi pouka, v katerem povzema svoja stališča glede različnih vidikov izobraževanja.Erasmus of Rotterdam is one of the leading figures of the Renaissance humanism. He wrote several influential works concerning upbringing and education. They contain his views about the correct forms of raising and teaching children that are necessary for obtaining optimal education. It should be based on acquiring an advanced knowledge of classical languages and on reading classical, which helps to form a child\u27s character. In his works Erasmus often focuses on the optimal qualifications of a teacher, who needs to be well-read in a wide spectre of different disciplines. He needs to have a pleasant personality, so the children will be fond of him and the learning will be as efficient as possible. In his writings on education Erasmus follows the examples of writers from antiquity and renaissance, as he considers the education of the middle ages to be of inferior quality. The present master thesis also contains a translation of Erasmus\u27 handbook for teachers, titled On the method of study, which contains author\u27s views on various aspects of education
Load bearing steel structures for industrial fabric buildings
Full text linkThe thesis deals with fabric structures, which are made of aluminium or steel frames covered with PVC membrane. First, we analyzed and according to the standard EN 1999-1-1 checked design of existing aluminum structures, which consist of specially designed extruded hollow sections. Such buildings are used for storage and sports facilities, they have low total mass and are very easy and quickly assembled. We analyzed structures of various spans and with different design loads and found out they are all optimally designed. In the next step we focused on a design of steel structures according to standard EN 1993-1-1 with the same technical characteristics as aluminium structures. Structures with different spans, grids, design snow loads and with a use of different strengths of structural steel were analyzed. To ensure smooth outer lines of the building use of rectangular and square hollow sections was dictated. Main goal of design was optimal consumption of material. In the last part of the thesis we dealt with concept and design of improved and optimized solutions for joints. Simple production and fast assembly had to be assured in order to get closer to competitive aluminium structures. We evaluated the results and came to the conclusion that\ud
use of steel in industrial fabric buildings with larger spans is better and thus also more competitive than the aluminium
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
ULS analysis of FRP composite sandwich plates - Sandwich PULS – development of a semi-analytical method
No full textThe use of fibre-reinforced polymers (FRP) composite sandwich structures is desirable because of their advantages compared to using steel structures. Many of the advantages are due to reduced weight, for example improved stability, lower fuel consumption, higher top speed, and increase in payload. Other advantages such as lower maintenance and long fatigue life contribute to an overall lower lifetime cost. A sandwich plate is a three-layer geometry consisting of two thin faces separated by a thick core. The purpose of this thesis is to develop Sandwich PULS; a semi-analytical calculation tool for predicting the ultimate limit state (ULS) of FRP composite sandwich plates. This was done by extending and improving DNV GL’s semi-analytical non-expert calculation tool Composite PULS, which is used for quick estimation of the ULS for unstiffened composite plates. ULS was evaluated in terms of the first buckling load and the first ply failure (FPF). The Sandwich PULS code was developed by implementing formulations for sandwich plate theory. First-order shear deformation theory (FSDT) was implemented in Sandwich PULS to include the transverse shear deformations that are highly important for sandwich plates with poor shear stiffness of the core. The Sandwich PULS code was evaluated against non-linear finite element analyses (FEA). It was concluded that Sandwich PULS shows good agreement with FEA predicted critical buckling loads. For all inspected plates, Sandwich PULS shows improved results compared to Composite PULS. Differences between Sandwich PULS and FEA are caused by the difference in evaluating shear stiffness. It has been shown that neglecting shear stiffness of faces results in good agreement between Sandwich PULS and FEA, while use of conventional shear correction factors proved to be unfavourable for sandwich plates. It was found that Sandwich PULS is limited in terms of slenderness. Sandwich plates with soft core should not have slenderness below 20 to assure an accurate solution. FPF loads according to Hashin-Rotem failure criteria are on the conservative side, but differences compared to FEA are up to 40% for sandwich plates. It was concluded that a more extensive investigation of failure initiation load prediction should be performed for better understanding

Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
