A FRAMEWORK FOR THE MEASUREMENT AND PREDICTION OF AN INDIVIDUAL SCIENTIST’S PERFORMANCE

Author(s): Endel Põder / Language(s): English / Issue: 1/2017

Quantitative bibliometric indicators are widely used to evaluate the performance of scientists. However, traditional indicators do not much rely on the analysis of the processes intended to measure and the practical goals of the measurement. In this study, I propose a simple framework to measure and predict an individual researcher’s scientific performance that attempts to take into account the main regularities of publication and citation processes and the requirements of practical tasks. Statistical properties of the new indicator – a scientist’s personal impact rate – are illustrated by its application to a sample of Estonian researchers.

A LOW TE(A)CH APPROACH TO DIGITAL HUMANITIES

Author(s): Liviu Pop / Language(s): English / Issue: 1/2017

Technological fatigue is spreading due to the increased arrays of technological branches and the rapid pace of development. Keeping up with the latest and newest might prove not only difficult and tiring, but also not necessarily recommended to beginners in digital humanities. A more “back to the basis” approach might be more useful for students that don’t have technical backgrounds.

A Practical Approach to Ascertaining the Accuracy and Resolution of Post Rendered 3D Models Acquired Originally via 3D Digitization

Author(s): Feng Zhao,Soo Choon Loy / Language(s): English / Issue: VII/2017

3D digitization is becoming the norm in the preservation of tangible cultural properties be it movable or immovable. In the case of mobile cultural objects, 3D models are normally acquired through non-destructive methods such as photogrammetry or 3D scanning using structured light or laser. The continuing improvements in scanning equipment which result in higher accuracy and resolution can be translated to mean higher level of 3D data acquired. At times, the quantity of 3D data of a single model can get too large and beyond what a normal work-station can process. This is where optimization comes in. However, the level of optimization will vary to suit the final purpose or usage of the 3D model. During optimization, the resulting optimized 3D model is bound to suffer from some level of data loss when compared to the original 3D model acquired directly from laser scanning. This paper discusses a practical method devised by Amber Digital Solutions in maintaining a high level of accuracy of the final optimized model for national archival purposes which requires the highest form of quality.

A SHORT HISTORY OF COMPUTER USE AT FACULTY OF PHYSICS – UNIVERSITY OF BUCHAREST

Author(s): Mircea Victor Rusu / Language(s): English / Issue: 2/2017

For physicists computing is a main activity. Starting from devising an experiment to problem solving with computer, from using mathematical tables to other aids to computation, physics has grown its strength by using each step the numerical computation. So, computing for researches as well as education was used and steadily improved by us, starting from first minicomputers to the last generation of computers and algorithms. In this presentation we will follow, in short, the evolution of computing, hard and soft, in physics at our faculty. We selected here the main field of interests that was connected with problems showing: programmed solutions, simulations and modeling, computer application and software during the time. Such a time recollection is interesting and surprises me as how diverse and far such activity was done. Examples will be from computation in tradition physics, to biology, chemistry, astronomy, medicine to data processing and visualization, data management, to create our own educational software and so on. The fields as nonlinear dynamics, complexity, chaos and fractals, as well as fluid dynamics, atomic, molecular or nuclear physics, earth or stellar physics, connected to improvement of the experiments and devices via artificial intelligence are some of our topics which will be exemplified here.

A Short Note on the Glagolitic Ornament in Pamvo Berynda’s Triod Cvetnaya (Kiev 1631)

Author(s): Sebastian Kempgen / Language(s): English / Issue: 14-15/2015

The article draws attention to two lesser known lines written in Glagolitic which are part of the Epilogue to Pamvo Berynda’s Triod Cvetnaja, printed in Kiev in 1631. Thanks to their typographic realisation, these two lines seem to have been mainly considered „an ornament“ or a „cryptographic“ element of the text in older literature. The article presents the Glagolitic text in standard Unicode encoding, so it becomes electronically searchable as such, along with a transliteration and a translation. It turns out that the Glagolitic text is nearly identical to the self-descriptions famout printer Pamvo Berynda had used before (although in Cyrillic). Another question put forth in the paper is the provenience of the actual printing types used in Kiev in 1631. A comparision shows that the letters look similar – but not identical – to printing type used around the same time Italy (Rome, Venice) or by Primož Trubar in the century before. The typographic quality of the Kievan types is, however, inferior.

Academia vs Forums: Official and Unofficial Knowledge – The “Case” of Cyril and Methodius

Author(s): Mišel Pavlovski,Loreta Georgievska-Jakovleva / Language(s): English / Issue: 10/2016

The digital (virtual) space is the place (some would go as far as to call it the most democratic of all spaces) where ideas and opinions clash, where new meanings are being created, where new values and beliefs are being forged. At the same time, digital space is the site where meaning is shaped and defined. This paper aims at exploring possible changes in meaning when examining Cyril and Methodius via digital space. Hence, said transformations practically help forge new meanings about the past. By situating Cyril and Methodius within the context of the virtual media space, this paper aims at examining how a culture’s heritage and its representation within digital time stand in direct correlation with the needs of contemporary politics and dominant discourses. Thus, the representations of Cyril and Methodius forged within the digital space breathe new meanings into old legacies, i.e., they de/construct and re/construct it. The research shows that said process, though mostly chaotic and partial, is always compatible with powerful (even if oftentimes contradictory) discourses. Along those lines, if juxtaposing the meaning of a culture’s heritage with said culture’s contemporality, we can in fact ascertain its function, meaning, and influence on contemporary cultural processes. Or, to paraphrase Simon During, to examine the ways in which past traces and representations enter contemporary (popular) culture.

Achieving Quality and Impact for Europe’s Library Collections

Author(s): Louise Edwards,Ismet Ovcina / Language(s): English / Issue: 08/2015

From 2015, The European Library will be an independent, not-for-profit library services organisation, supported by CENL, LIBER and CERL. Our vision is to be the most important hub for libraries’ data in Europe. With a dataset of over 200 million records, we collaborate closely with trusted partners to develop services that maximize the impact of libraries’ data. We operate on the principles of openness and inclusivity. Affordable membership is available to all national and research libraries from the 47 Council of Europe states. The benefits to libraries are to make data work in ways that are cost-effective. We aggregate, enrich and improve data, and distribute it into the workflows of users. We return the enhanced data back to libraries to improve their own systems and processes. We are involved in innovative projects that demonstrate the application of data in new products and services. Examples include cloudbased infrastructures, full text search and browse, collection descriptions to promote the discovery of hidden resources, and linked open data for the semantic web. We are a best practice network for the sharing of knowledge and expertise. The presentation will highlight some of the services offered by The European Library, with a special focus on the libraries and collections of the Balkan region.

Analiza graficzna danych edukacyjnych z wykorzystaniem języka Python

Author(s): Jakub Swacha / Language(s): Polish / Issue: 2/2016

In practice, the high quality of educational processes and content can hardly be achieved and maintained without monitoring. And since tracking the results is not enough, it is necessary to find existing flaws and identify their causes. In this paper, it is argued that even small data sets such as students' test results can provide valuable information useful to improve further iterations of teaching and learning outcomes verification processes and educational materials. Next, the appropriateness of graphical analysis for this purpose is pointed out taking its simplicity even for non-statisticians and its ability to visualize entire small data sets with high precision into account. However, the primary aim of this paper is to provide practical examples showing that the Python programming language (with a selection of specialized modules) can be used in a convenient and effective manner for graphical analysis of small educational data sets. For the purpose of demonstration case study, actual test results were used. Analysis examined: correctness and confidence of students answering respective test questions, correlations between results based on question type and relevant content area, and also similarities of answers given by different students. Also, a Python-based software environment for graphical analysis has been compared to Microsoft Excel.
