Semi-automatic generation of learning domain modules for technology supported learning systems

In a time when Technology Supported Learning Systems are being widely used, there is a lack of tools that allows their development in an automatic or semi-automatic way. Technology Supported Learning Systems require an appropriate Domain Module, ie. the pedagogical representation of the domain to be mastered, in order to be effective. However, content authoring is a time and effort consuming task, therefore, efforts in automatising the Domain Module acquisition are necessary.Traditionally, textbooks have been used as the main mechanism to maintain and transmit the knowledge of a certain subject or domain. Textbooks have been authored by domain experts who have organised the contents in a means that facilitate understanding and learning, considering pedagogical issues.Given that textbooks are appropriate sources of information, they can be used to facilitate the development of the Domain Module allowing the identification of the topics to be mastered and the pedagogical relationships among them, as well as the extraction of Learning Objects, ie. meaningful fragments of the textbook with educational purpose.Consequently, in this work DOM-Sortze, a framework for the semi-automatic construction of Domain Modules from electronic textbooks, has been developed. DOM-Sortze uses NLP techniques, heuristic reasoning and ontologies to fulfill its work. DOM-Sortze has been designed and developed with the aim of automatising the development of the Domain Module, regardless of the subject, promoting the knowledge reuse and facilitating the collaboration of the users during the process.

Benthic sampling program in Biscayne Bay, 1981-1982

The Biscayne Bay Benthic Sampling Program was divided into two phases. In Phase I, sixty sampling stations were established in Biscayne Bay (including Dumfoundling Bay and Card Sound) representing diverse habitats. The stations were visited in the wet season (late fall of 1981) and in the dry season (midwinter of 1982). At each station certain abiotic conditions were measured or estimated. These included depth, sources of freshwater inflow and pollution, bottom characteristics, current direction and speed, surface and bottom temperature, salinity and dissolved oxygen, and water clarity was estimated with a secchi disk. Seagrass blades and macroalgae were counted in a 0.1-m2 grid placed so as to best represent the bottom community within a 50-foot radius. Underwater 35-mm photographs were made of the bottom using flash apparatus. Benthic samples were collected using a petite Ponar dredge. These samples were washed through a 5-mm mesh screen, fixed in formalin in the field, and later sorted and identified by experts to a pre-agreed taxonomic level. During the wet season sampling period, a nonquantitative one-meter wide trawl was made of the epibenthic community. These samples were also washed, fixed, sorted and identified. During the dry season sampling period, sediment cores were collected at each station not located on bare rock. These cores were analyzed for sediment size and organic composition by personnel of the University of Miami. Data resulting from the sampling were entered into a computer. These data were subjected to cluster analyses, Shannon-Weaver diversity analysis, multiple regression analysis of variance and covariance, and factor analysis. In Phase II of the program, fifteen stations were selected from among the sixty of Phase I. These stations were sampled quarterly. At each quarter, five Petite Ponar dredge samples were collected from each station. As in Phase I, observations and measurements, including seagrass blade counts, were made at each station. In Phase II, polychaete specimens collected were given to a separate contractor for analysis to the species level. These analyses included mean, standard deviation, coefficient of dispersion, percent of total, and numeric rank for each organism in each station as well as number of species, Shannon-Weaver taxa diversity, and dominance (the compliment of Simpson's Index) for each station. Multiple regression analysis of variance and covariance, and factor analysis were applied to the data to determine effect of abiotic factors measured at each station. (PDF contains 96 pages)

Thermocline topography, horizontal currents and “ridging” in the Eastern Tropical Pacific

ENGLISH: A primary objective of the Inter-American Tropical Tuna Commission is a knowledge of the ecology of tunas which inhabit the Eastern Tropical Pacific. This paper presents some results of the work in physical oceanography, which, it is hoped, will be useful to the biological work and at the same time of interest to physical oceanographers. The work presented here was begun in connection with simple observable facts; the thermocline is very close to the sea surface in a region off Costa Rica (Wooster and Cromwell, 1958), and this region is biologically productive (Holmes, et al. 1957; Brandhorst, 1958). It is the main object of this study to describe and explain these facts, insofar as possible. SPANISH: Uno de los principales objetivos de la Comisión Interamericana del Atún Tropical es el conocimiento de la ecología de los atunes que viven en el Pacífico Oriental Tropical. Este informe presenta algunos de los resultados del estudio en oceanografía física, los cuales se espera que serán útiles en la investigación biológica y, al mismo tiempo, de interés para los oceanógrafos físicos. El trabajo presentado aquí se inició en conexión con sencillos hechos observables; mar afuera de Costa Rica, la termoclina queda muy cerca de la superficie del mar (Wooster y Cromwell, 1958) y esta región es biológicamente productiva (Holmes, el al., 1957; Brandhorst, 1958). El objeto principal de este estudio es describir y explicar estos hechos, hasta donde sea posible. (PDF contains 32 pages.)

Diário da Constituinte [gravação de vídeo] : [programa n. 411]

A Assembleia Nacional Constituinte começa hoje uma nova fase. Agora tudo o que for decidido e votado neste Plenário vai ter força de Lei. E força de Lei Maior, força de Constituição. Muita discussão e muitas horas sem dormir já foram gastas. Foram produzidos 66.197 documentos entre projetos e emendas. Foram enviadas 72.719 sugestões a Constituinte, de todas as partes do país. E mais de 10 milhões de brasileiros assinaram emendas populares. Mudanças importantes já foram discutidas e aprovadas nas etapas anteriores. A Constituição que começa a ser votada é a 7ª Carta que o Brasil tem. Há 164 anos o país começou a ser juridicamente organizado. Surgia a 1ª Constituição do Brasil, a Constituição do Império. A mudança surgiu com a Proclamação da República. A nova Carta foi votada em 1891. Serviu à Velha República e sofreu mudanças em 1934 e depois em 1937, com o Estado Novo. A redemocratização surgiu em 1946, durou até 1967, quando foi alterada depois da Revolução Militar, de março de 1964. A nova Carta começa a ser votada, com o compromisso dos constituintes de executá-la no tempo justo.

Neue Chance für den Nordsee-Kabeljau: Seevögel machen bereits im Sommer 2001 auf starken Jahrgang aufmerksam

Im Oktober/November des vergangenen Jahres ergab sich während der 483. Reise von FK „Solea“ ein im Vergleich zu den vier Vorjahren hoher Fangindex von 220 Kabeljau Gadus morhua je Stunde (Weber 2001). Die Fische hatten eine Länge von 15 bis18 cm und waren besonders in Küstennähe Ostfrieslands anzutreffen. Durch unsere Langzeituntersuchungen zur Ökologie der Flussseeschwalbe Sterna hirundo im Wattenmeer sind wir bereits im Juni des Jahres 2001 auf den starken Jahrgang des Kabeljaus aufmerksam geworden und können die Vermutung von Weber bestätigen, dass die Kabeljaus den Sommer über im Wattengebiet herangewachsen sind.

Schwacher Nachwuchsjahrgang 2001 des Herings in der westlichen Ostsee

Several fishery independent estimates of the year-class strength are necessary for the assessment and the management of the total fish stock. An index for the year-class strength of the spring spawning herring in the western Baltic Sea is estimated on the basis of larvae surveys in the most important spawning ground. The results indicate a weak year-class 2001.
