La mejora de las capacidades de búsqueda y de las interfaces de los OPACs sigue siendo uno de los principales desafíos para las bibliotecas, especialmente en lo que respecta al acceso por materias. Las interfaces visuales pueden ser una alternativa para facilitar la recuperación. El objetivo del presente trabajo es explorar si la combinación de técnicas de análisis de co-términos y de redes sociales resulta ser una metodología válida para la generación de mapas temáticos de la colección. La principal conclusión es que el método es válido, y que los mapas obtenidos podrían servir tanto como una alternativa de interfaz visual para el acceso por materias, como también para detectar problemas en los criterios de indización, y contribuir a la mejora de la calidad de la descripción temática del conjunto documental

O presente estudo analisa algumas ressignificações simbólicas dos Antigos Cultos de Mistério, bem como alguns desdobramentos de suas realidades históricas. Essa dissertação avalia os possíveis fluxos e trocas ocorridos nos entornos mediterrâneos, concentrando-se nas ressignificações que os mistérios sofreram nessas fronteiras, discorrendo igualmente sobre sua possível influência numa perícope bíblica. Na investigação serão levantadas hipóteses referentes a relação dos cultos mistéricos com a expansão helenística, bem como suas possíveis interfaces com uma fonte primária do Novo Testamento. Com base no estudo dos principais mistérios presentes nas fronteiras romanas, e na avaliação da literatura neotestamentária, serão consideradas as aproximações e distanciamentos simbólicos entre o culto Dionisíaco e o texto de João 2, 1-11.

When combining remote sensing imagery with statistical classifiers to obtain categorical thematic maps it is not usual to provide data about the spatial distribution of the error and uncertainty of the resulting maps. This paper describes, in the context of GeoViQua FP7 project, feasible approaches for methods based on several steps such as hybrid classifiers. Both for “per pixel” and “per polygon” strategies, the proposal is based on the use of the available ground truth, which is used to properly model the spatial distribution of the errors. Results allow mapping the classification success with a very high level of reliability (R2>0,94), providing users a sound knowledge of the accuracy at every area of the map.

BACKGROUND: Among the wide range of skills displayed by a medical doctor is undoubtedly the need to use cohesive and well grounded clinical reasoning in order for medical care to be indeed effective. It is in this respect that conceptual maps emerge; these are a methodological innovation that allows a comprehensive, panoramic and associative outlook of theoretical content, making it more practical and applicable to the reality of clinical observation. Promoting learning, learning resources and a feedback system between professor and students, as well as assessing and monitoring the performance of students during their academic training, are the main features of this tool. OBJETIVE: Assess the use of conceptual maps as a teaching-learning tool in the training of undergraduate medical students at Universidade Federal do Rio Grande do Norte (UFRN). METHODOLOGY: Interventional, randomized, cross-sectional study conducted with students from the 3rd and 5th periods of the medical course at UFRN, during the second semester of 2014, totaling 86 participants, divided into two groups: GI (intervention – clinical case resolution with a conceptual map) and GII (control – clinical case resolution without a conceptual map) in each period. RESULTS: The use of conceptual maps to teach liver failure syndrome resulted in a statistically significant cognitive gain for G1 students from the 5th period (GI: 6.8±1.6 and 8.0±1.5, p = 0.024; GII: 7.2±2.1 and 8.0±1.7, p = 0.125, pre and post-intermediate means, respectively), a result not observed in the period 3rd (GI: 7.7±1.3 and 8.0±1.4, p = 0.501; GII: 6.7±1.8 and 7.8±1.8; p=0.068, pre and post-intermediate means, respectively). Students in the 3 rd period gave better responses to the first clinical case, with a larger number of suitable concepts and crosslinks, when they used conceptual maps (GI: 91.3±13.15 and GII: 64.84±22.84, p=0,002). Students in the 5th period exhibited better clinical reasoning and more complete responses using the tool (p=0,01). Most of the students were not aware of the tool (53.8% from the 3rd period and 65.3% from the 5th period). Among those who knew about conceptual maps, most (59.3%) had only used them during high school, 14.8% had never used them and only seven students (25.9%) used them during the medical course. Analysis of open responses, obtained in process assessment showed clear satisfaction and enthusiasm with learning about the new tool, and frequent suggestions to use it at other moments in the course. Assessment of learning profile, using the VARK questionnaire, showed that most students from both periods exhibited a multimodal style. CONCLUSION: Despite their scant knowledge regarding the tool, good acceptability and understanding was observed in the study participants. The conceptual maps allowed cognitive gains, better responses and clinical reasoning in teaching liver failure syndrome to 5th period students.

This essay aims to present and describe a proposal of insertion of Mathematics History into teachers undergraduation. Such addition proposal is expected to take place as curricular component to be taught on initial undergraduation for mathematics teachers. The selection of contents for the proposal has been based on the national Curriculum Guidelines (DCN, 2001, acronym in portugueses) for bachelor’s degree in Mathematics; the National Curricular Guidelines for Elementary School (PCNEF, 1998, acronym in Portuguese); and the National Curricular Guidelines for High School (PCNEM, 1999, acronym in Portuguese). The curricular component now presented is supposed to take a 60 hour workload, and includes the following topics: History of Ancient Numbering Systems, History of Trigonometriy and History of fuctions. For the sake of exemplification, the topic History of Ancient Numbering Systems is discussed and analysed in detail as practice for the new curricular component.

Nowadays, the amount of customers using sites for shopping is greatly increasing, mainly due to the easiness and rapidity of this way of consumption. The sites, differently from physical stores, can make anything available to customers. In this context, Recommender Systems (RS) have become indispensable to help consumers to find products that may possibly pleasant or be useful to them. These systems often use techniques of Collaborating Filtering (CF), whose main underlying idea is that products are recommended to a given user based on purchase information and evaluations of past, by a group of users similar to the user who is requesting recommendation. One of the main challenges faced by such a technique is the need of the user to provide some information about her preferences on products in order to get further recommendations from the system. When there are items that do not have ratings or that possess quite few ratings available, the recommender system performs poorly. This problem is known as new item cold-start. In this paper, we propose to investigate in what extent information on visual attention can help to produce more accurate recommendation models. We present a new CF strategy, called IKB-MS, that uses visual attention to characterize images and alleviate the new item cold-start problem. In order to validate this strategy, we created a clothing image database and we use three algorithms well known for the extraction of visual attention these images. An extensive set of experiments shows that our approach is efficient and outperforms state-of-the-art CF RS.

Este trabajo intenta reconstruir las prácticas visuales de relevamiento de los topógrafos de la Dirección de Minas. En este caso analizaremos los materiales visuales que realizó Felipe E. Godoy Bonnet para la realización de la Hoja topográfica Sierra Apeleg (1980). En el proceso de construcción de la cartografía topográfica encontramos distintas instancias: gabinete / precampo, campo y gabinete / poscampo. En cada una de ellas, el topógrafo es capaz de construir diferentes tipos de paisajes, aunque todos remitan al mismo espacio. En la primera de estas etapas, el topógrafo comienza a visualizar mentalmente un paisaje (paisaje topográfico imaginado) a partir de la observación de materiales cartográficos recopilados antes de aventurarse en el terreno. En la segunda, ya en el campo, el topógrafo activa su agudeza visual para reconstruir y reformular el paisaje previamente imaginado y lo completa con datos empíricos (paisaje topográfico medido). En la etapa de trabajo de poscampo, se comienza a dibujar -en lenguaje cartográfico- el paisaje que imaginó, vio y midió el topógrafo (paisaje topográfico dibujado). Una vez terminado el trabajo, cualquier observador entrenado en los códigos cartográficos puede decodificar y leer el mapa, dar volumen a las líneas de nivel y (re)construir un nuevo paisaje topográfico imaginado (ya que el mapa se puede convertir en un insumo para ir a relevar nuevamente el terreno). Intentamos establecer los primeros lineamientos para pensar qué son los paisajes topográficos, la variedad de registros que implican, los lenguajes que articulan y cómo es el proceso que ayuda a su construcción. A su vez, pensamos que la construcción de los paisajes topográficos varía a lo largo del proceso cartográfico y de sus lecturas posteriores. Esas variaciones pueden ser pensadas en términos de un agenciamiento, como lo propone Alfred Gell (1997).
