Base de datos estadísticos de las bibliotecas de la Universidad Nacional de La Plata : una experiencia cooperativa

In October 2001, there were formed the Interlibraries Task Forces (ITF) in the field of libraries of the UNLP with the idea of moving in various joint projects and form a network, whose face visible is Portal ROBLE (www.roble.unlp.edu.ar). Among the teams, the ITF Evaluation of Information Units, was established with the aim of developing "management indicators applicable to all libraries of the UNLP in order to measure and diagnose them, facilitating decision making and processes of continuous improvement". Within this framework, we developed a standardized statistical survey of libraries basic data, which took into account the existing international norms and standards on the issue, as well as developments implemented in various countries for the realization of university libraries statistics. Among others, were consulted developments of SCONUL (UK), REBIUN (Spain), CAUL (Australia) and ASIBU (France). The statistical form was applied to all participating libraries in the network ROBLE in 2001 and 2004, and its results were published in two separate statistical yearbooks. In both cases, the survey data was performed based on a spreadsheet that libraries completed and sent to the task force for central processing and analysis. Although the methodology reached the expected results, there were presented the following problems: manual processing of the data was extremely cumbersome and prone to human errors in typing, tailoring and subsequent publication of the Statistical Yearbooks delayed a minimum of two years of work, since there was no staff dedicated exclusively to this task, processed data were not registered in a public place or were easily accessible, so any subsequent study was difficult to implement, and, because of the excesive delay in processing, there was no time to move on comparative or more developed studies among libraries (benchmarking, second-level indicators, impact indicators, etc.). For these reasons, during 2007 funds were managed to develop a Web application that would allow us to automate the statistical survey and generate a data base with all the data of the UNLP libraries collected since 2001. While the application is still in a state of development, the first phase (data loading and viewing performance indicators) is being used in beta-test mode. Part of this work was presented at the Workshop Indicators for Assessing Libraries (Taller de Indicadores de Evaluación de Bibliotecas, http://tieb.fahce.unlp.edu.ar) held in La Plata at December 2007 with the aim of extending its application to others university libraries in Argentina. This paper describes the experience of the team UNLP in collecting standardized statistical data, analysis and processing, the WEB application designed, the problems encountered and future lines of work for the implementation of the Project “Library Statistics Database of Argentine University Libraries”

Desarrollo de repositorios digitales institucionales en las universidades nacionales en Argentina, período 2004-2015

The present paper is part of a thesis under development of the CTS Masters program of the National University of Quilmes, whose objective is to know the current situation and the process of development of institutional digital repositories in Argentine's national universities in the period 2004-2015

Greenstone: Uso actual en Argentina

This paper presents the characteristics and history of the software Greenstone to create and manage digital libraries, initially developed by the University of Waikato, New Zealand in 1997. First, the user community is described at a global level, focusing on the current use that the software has achieved in Argentina: the number of implementations available, their evolution, the type, size and variety of the existing developments, as well as their application to the management of digital repositories of science and technology in the field of scientific, technological and higher education institutions in Argentina. Secondly, the actions carried out after the creation of the National Center for the Promotion of Greenstone in Argentina in 2009 are detailed. Data collected from surveys made it possible to observe that the predominant reasons for choosing this platform were, among others, its ease of installation and configuration, its low level of technological requirements, the general scarcity of human resources dedicated to this activity, and the complexity of the alternative software existing at that time. Throughout these 8 years, both the digital repositories and the systems that support them evolved drastically, modifying the current scenario. In parallel, in 2016 the new major version of Greenstone implemented a complete re-engineering of the software to adapt it to the technologies in use: XML, XSLT, Web-services and Java. As a consequence of this, the local development community poses new challenges for the migration of digital libraries and repositories implemented with previous versions

UC-338 Chiba

The core mechanic present in Chiba is pushing around food items to plate tiles. Each time the player pushes a food item it incurs a cut. With enough cuts the food item will be cut into pieces, progressing to the next cut stage - with a max stage of cuts available for the different pieces of food. This is fundamentally built upon the core gameplay mechanic in Sokoban. Additionally, extending upon this further by incorporating new mechanics such as grilling food items and utilizing slick and sticky tiles. Together, these mechanics allow for a unique series of puzzles to test the players\u27 spatial reasoning. Furthermore, players are disallowed from pushing any one piece of food too many times because the food crumbles and breaks after a certain point. This causes them to be forced to restart the level. Players need to balance both navigation and finding the shortest possible paths in order to push the food to the plates to complete the level. If players complete a level in under a certain number of moves, they can earn a star for that level. Players can earn up to three stars per level if they make the minimum number of pushes possible. As the levels progress, more mechanics are added to give players more ways to solve levels. For example, meatballs were added that rolled until they hit something instead of moving a single tile. With additional mechanics like rolling, players are introduced to more complicated levels that allow them to consider more solutions, while also restricting other solutions

UC-336 Concrete formwork simulator

Concrete Formwork Simulator is a simulation game meant to help construction students practice their skills. The goal of the game is to successfully build concrete formwork with the least amount of wasted materials. Players are scored out of 400 on each of the individual stages: shop, cut, and assemble. Players choose between building a formwork for a column, a slab, and a wall. Each formwork has its own set of materials for the players to buy, cut, and assemble. The player will need to take the dimensions of the formwork into account and then calculate the minimum number of each piece of lumber they will need to buy. Then, while considering minimizing waste, they need to calculate if any pieces need to be cut, and how much to cut them. Finally, the Player moves to the assembly where they are instructed to build the formwork of their choice. They must follow the correct order of assembly and build the sections of the formwork in the correct order to receive full points for the assembly stage. If they have done everything correctly, they will receive a perfect score of 1200 for that formwork

The performance of thin NaI(Tl) scintillator plate for dark matter search

A thin (0.05cm) and wide area (5cmX5cm) NaI(Tl) scintillator was developed. The performance of the thin NaI(Tl) plate, energy resolution, single photoelectron energy and position sensitivity were tested. An excellent energy resolution of 20% (FWHM) at 60keV was obtained. The single photoelectron energy was calculated to be approximately 0.42 0.02keV. Position information in the 5cmx5cm area of the detector was also obtained by analyzing the ratio of the number of photons collected at opposite ends of the detector. The position resolution was obtained to be 1cm (FWHM) in the 5cmx5cm area.Comment: 10 pages. Accepted to Journal of Physical Society of Japa

Light Neutralinos as Dark Matter in the Unconstrained Minimal Supersymmetric Standard Model

The allowed parameter space for the lightest neutralino as the dark matter is explored using the Minimal Supersymmetric Standard Model as the low-energy effective theory without further theoretical constraints such as GUT. Selecting values of the parameters which are in agreement with present experimental limits and applying the additional requirement that the lightest neutralino be in a cosmologically interesting range, we give limits on the neutralino mass and composition. A similar analysis is also performed implementing the grand unification constraints. The elastic scattering cross section of the selected neutralinos on $^{27}$Al and on other materials for dark matter experiments is discussed.Comment: Submitted to Astroparticle Physics, 19 Feb. 96, Latex 23 pages with 24 figures in a gzip compressed file FIGURE.PS.GZ available via anonymous ftp from ftp://iws104.mppmu.mpg.de/pub/gabutt
