    The high heterogeneity of biomedical vocabulary is a major obstacle for information retrieval in large biomedical collections. Therefore, using biomedical controlled vocabularies is crucial for managing these contents. We investigate the impact of query expansion based on controlled vocabularies to improve the effectiveness of two search engines. Our strategy relies on the enrichment of users' queries with additional terms, directly derived from such vocabularies applied to infectious diseases and chemical patents. We observed that query expansion based on pathogen names resulted in improvements of the top-precision of our first search engine, while the normalization of diseases degraded the top-precision. The expansion of chemical entities, which was performed on the second search engine, positively affected the mean average precision. We have shown that query expansion of some types of biomedical entities has a great potential to improve search effectiveness; therefore a fine-tuning of query expansion strategies could help improving the performances of search engines.

  7. EEG Beta Power but Not Background Music Predicts the Recall Scores in a Foreign-Vocabulary Learning Task.

    2016-01-01

    As tantalizing as the idea that background music beneficially affects foreign vocabulary learning may seem, there is-partly due to a lack of theory-driven research-no consistent evidence to support this notion. We investigated inter-individual differences in the effects of background music on foreign vocabulary learning. Based on Eysenck's theory of personality we predicted that individuals with a high level of cortical arousal should perform worse when learning with background music compared to silence, whereas individuals with a low level of cortical arousal should be unaffected by background music or benefit from it. Participants were tested in a paired-associate learning paradigm consisting of three immediate word recall tasks, as well as a delayed recall task one week later. Baseline cortical arousal assessed with spontaneous EEG measurement in silence prior to the learning rounds was used for the analyses. Results revealed no interaction between cortical arousal and the learning condition (background music vs. silence). Instead, we found an unexpected main effect of cortical arousal in the beta band on recall, indicating that individuals with high beta power learned more vocabulary than those with low beta power. To substantiate this finding we conducted an exact replication of the experiment. Whereas the main effect of cortical arousal was only present in a subsample of participants, a beneficial main effect of background music appeared. A combined analysis of both experiments suggests that beta power predicts the performance in the word recall task, but that there is no effect of background music on foreign vocabulary learning. In light of these findings, we discuss whether searching for effects of background music on foreign vocabulary learning, independent of factors such as inter-individual differences and task complexity, might be a red herring. Importantly, our findings emphasize the need for sufficiently powered research designs and exact replications

    Predictions from theories of the processes of word reading acquisition have rarely been tested against evidence from exceptionally early readers. The theories of Ehri, Share, and Byrne, and an alternative, Knowledge Sources theory, were so tested. The former three theories postulate that full development of context-free letter sounds and awareness of phonemes are required for normal acquisition, while the claim of the alternative is that with or without such, children can use sublexical information from their emerging reading vocabularies to acquire word reading. Results from two independent samples of children aged 3-5, and 5 years, with mean word reading levels of 7 and 9 years respectively, showed underdevelopment of their context-free letter sounds and phoneme awareness, relative to their word reading levels and normal comparison samples. Despite such underdevelopment, these exceptional readers engaged in a form of phonological recoding that enabled pseudoword reading, at the level of older-age normal controls matched on word reading level. Moreover, in the 5-year-old sample further experiments showed that, relative to normal controls, they had a bias toward use of sublexical information from their reading vocabularies for phonological recoding of heterophonic pseudowords with irregular consistent spelling, and were superior in accessing word meanings independently of phonology, although only if the readers were without exposure to explicit phonics. The three theories were less satisfactory than the alternative theory in accounting for the learning of the exceptionally early readers.

    1987-01-01

    The NASA Lewis Research Center supports many research facilities with many isolated buildings, including wind tunnels, test cells, and research laboratories. These facilities are all located on a 350 acre campus adjacent to the Cleveland Hopkins Airport. The function of NASA-Lewis is to do basic and applied research in all areas of aeronautics, fluid mechanics, materials and structures, space propulsion, and energy systems. These functions require a great variety of remote high speed, high volume data communications for computing and interactive graphic capabilities. In addition, new requirements for local distribution of intercenter video teleconferencing and data communications via satellite have developed. To address these and future communications requirements for the next 15 yrs, a project team was organized to design and implement a new high speed communication system that would handle both data and video information in a common lab-wide Local Area Network. The project team selected cable television broadband coaxial cable technology as the communications medium and first installation of in-ground cable began in the summer of 1980. The Lewis Information Network (LINK) became operational in August 1982 and has become the backbone of all data communications and video.

  4. How does background information improve memory for text content?

    PubMed

    Rawson, Katherine A; Kintsch, Walter

    2002-07-01

    In two experiments, we investigated whether reading background information benefits memory for text content by influencing the amount of content encoded or the organization of the encoded content. In Experiment 1, half of the participants read background information about the issues to be discussed in the text material, whereas half did not. All the participants were then tested for free recall and cued recall of text content. Free recall was greater for individuals who read issue information than for those who did not. The groups did not differ on cued recall, suggesting that background information did not facilitate the encoding of more text content. Measures of representational organization indicated that increased recall in the issue information group resulted from better organization of content in memory. Experiment 2 extended these findings, using background information about text sources, demonstrated that the efficacy of background information depends on the semantic relationship between that information and text content.

    2015-01-01

    This study used eye tracking to investigate the allocation of attention to multimodal stimuli during an incidental learning situation, as well as its impact on subsequent explicit learning. Participants were exposed to foreign language (FL) auditory words on their own, in conjunction with written native language (NL) translations, or with both written NL translations and pictures. Incidental acquisition of FL words was assessed the following day through an explicit learning task where participants learned to recognize translation equivalents, as well as one week later through recall and translation recognition tests. Results showed higher accuracy scores in the explicit learning task for FL words presented with meaning during incidental learning, whether written meaning or both written meaning and picture, than for FL words presented auditorily only. However, participants recalled significantly more FL words after a week delay if they had been presented with a picture during incidental learning. In addition, the time spent looking at the pictures during incidental learning significantly predicted recognition and recall scores one week later. Overall, results demonstrated the impact of exposure to multimodal stimuli on subsequent explicit learning, as well as the important role that pictorial information can play in incidental vocabulary acquisition.

  12. The Solar Background Spectrum: a Gold Mine of Information

    NASA Astrophysics Data System (ADS)

    Severino, G.; Straus, Th.; Jefferies, S. M.

    We discuss the properties of the intensity-velocity (I-V) phase difference spectra generated from 15 hours of high resolution MDI observations. These spectra provide a spectacular demonstration of the wealth of untapped information that is available on the nature of the solar background. In this context, the regimes of coherent phase in between the modes (``interridges'') and between the f mode and the Lamb waves (``plateau''), first discovered by Deubner et al. 1990, is of extreme interest. Understanding the background is important for several reasons: (i) it contains information about the convection processes and the wave propagation characteristics of the solar atmosphere in addition to that provided by the resonant oscillations, (ii) its interaction with the p-modes may explain why the sense of the asymmetry in the p-mode line profiles depends on the dynamic variable observed (Roxburgh & Vorontsov 1997, Nigam et al. 1998), (iii) estimates for the p-mode line asymmetries are sensitive to errors in the background determination, and (iv) the background limits the g-mode and low frequency p-mode visibilities. We also propose a new model for the solar background which uses the observed phase information: previous models (e.g. Harvey 1985) are restricted to power information only. Currently, our model is limited to low frequencies (1 mHz <= ν <= 3.5 mHz) and intermediate to high ell values, however, it still demonstrates the potential of the phase information to improve our estimates of the background components of both the velocity and intensity signals. A superposition of a correlated background and the p-mode signal succeeds in reproducing the observed I-V phase transition from negative (background) to positive (p-mode) values. Moreover, the model suggests that the background is responsible for the values of I-V phase, equal to or less than the adiabatic values observed in the low photosphere (Hill et al, 1991).

    Geological Survey of Japan has published series of geological map at 1:50,000. The study attempts to acquire, distribute, and utilize the outcrop information as digital information. We aim at construction of an open system which is available in a various position, and then establishment of standard technology for the realization of the system. The purpose of this paper is to consider and carry out manufacture of “Outcrop Information Vocabulary(OIV)” as the first stage of the study. Since outcrop information is basic primary information, the semantic web technology is employed to associate with various other systems on the Web; for instance, OIV is designed with use of ontology and described by Web Ontology Language(OWL). The OIV includes 14 classes including “FieldObservation” class to describe field observation. Moreover, we create test system which field researchers use to test the effectiveness of OIV. The result lead to the conclusion that files created by use of OIV are easy of mutual alteration and association function with other XML-base format, therefore, OIV has high affinity with existing technology.

    1981-01-01

    Instructors who are very familiar with a study area, as well as those who are not, find the field trip information acquisition and planning process speeded and made more effective by organizing it in stages. The stage follow a deductive progression: from the associated context region, to the study area, to the specific sample window sites, and from generalized background information on the study region to specific technical data on the environmental and human use systems to be interpreted at each site. On the class trip and in the follow up laboratory, the learning/interpretive process are at first deductive in applying previously learned information and skills to analysis of the study site, then inductive in reading and interpreting the landscape, imagery, and maps of the site, correlating them with information of other samples sites and building valid generalizations about the larger study area, its context region, and other (similar and/or contrasting) regions.

    2010-08-01

    The present experiments explored the resolution of activated background information in text comprehension. In Experiment 1, participants read passages that contained an elaboration section that was either consistent or qualified (inconsistent but then corrected to be consistent) with respect to the subsequently presented target sentence (see O'Brien et al., 1998). However, the experiment used two target sentences, and several filler sentences were inserted between the first and second target sentence. The results showed that the reading times for the first target sentence in the qualified elaboration version were significantly longer than those in the consistent elaboration version. These were consistent with O'Brien's study, and further indicated that the basic process captured by the memory-based view appears to generalize to the Chinese reader better than does the here-and-now view. More importantly, the results showed that the reading times for the second target sentence in the qualified elaboration version were as long as those in the consistent elaboration version. These further indicated that the activation of background information not only maintained the coherence of the text, but also allowed for the relevant information to be updated, resulting in a unified information set. When the information was reactivated during ongoing reading, it would be in the form of unified information. In Experiment 2, the first target sentence in each passage from Experiment 1 was converted to a filler sentence, and the second target sentence became the target sentence. The results of Experiment 2 showed that the reading times for the target sentence in the qualified elaboration version were significantly longer than those for the consistent elaboration version. These indicated that the delay between the target sentences and the elaboration section was not responsible for the lack of differences in Experiment 1, and confirmed the conclusion of Experiment 1.

  17. The information content of cosmic microwave background anisotropies

    NASA Astrophysics Data System (ADS)

    Scott, Douglas; Contreras, Dagoberto; Narimani, Ali; Ma, Yin-Zhe

    2016-06-01

    The cosmic microwave background (CMB) contains perturbations that are close to Gaussian and isotropic. This means that its information content, in the sense of the ability to constrain cosmological models, is closely related to the number of modes probed in CMB power spectra. Rather than making forecasts for specific experimental setups, here we take a more pedagogical approach and ask how much information we can extract from the CMB if we are only limited by sample variance. We show that, compared with temperature measurements, the addition of E-mode polarization doubles the number of modes available out to a fixed maximum multipole, provided that all of the TT, TE, and EE power spectra are measured. However, the situation in terms of constraints on particular parameters is more complicated, as we explain and illustrate graphically. We also discuss the enhancements in information that can come from adding B-mode polarization and gravitational lensing. We show how well one could ever determine the basic cosmological parameters from CMB data compared with what has been achieved with Planck, which has already probed a substantial fraction of the TT information. Lastly, we look at constraints on neutrino mass as a specific example of how lensing information improves future prospects beyond the current 6-parameter model.

    During the contract period the background necessary to proceed with the assembly and testing of the precision He(3) nuclear gyroscope was completed. This background work included experiments on He(3)-He(4) liquid and gas mixtures in a prototype apparatus which was modified to provide additional information useful to the He(3) gyroscope research program. The precision quartz He(3) gyroscope was designed, constructed and delivered during the period as were the components of the airlock and cryostat probe assembly. A new ultra-low magnetic field shield was made which achieved 2 x 10 to the 8th power/G over the volume necessary for the He(3)gyroscope. This not only exceeds the nominal requirements of the He(3) gyroscope, but is the lowest magnetic field region ever made. An engineering Ph.D thesis was completed by Captain Gerald Shaw, working with professor Daniel DeBra, on a theoretical analysis of the cross-axis response of a three-axis He(3) gyroscope and on kinematic rectification in a nuclear gyro.

    Can knowledge help viewers when they appreciate an artwork? Experts’ judgments of the aesthetic value of a painting often differ from the estimates of naïve viewers, and this phenomenon is especially pronounced in the aesthetic judgment of abstract paintings. We compared the changes in aesthetic judgments of naïve viewers while they were progressively exposed to five pieces of background information. The participants were asked to report their aesthetic judgments of a given painting after each piece of information was presented. We found that commentaries by the artist and a critic significantly increased the subjective aesthetic ratings. Does knowledge enable experts to attend to the visual features in a painting and to link it to the evaluative conventions, thus potentially causing different aesthetic judgments? To investigate whether a specific pattern of attention is essential for the knowledge-based appreciation, we tracked the eye movements of subjects while viewing a painting with a commentary by the artist and with a commentary by a critic. We observed that critics’ commentaries directed the viewers’ attention to the visual components that were highly relevant to the presented commentary. However, attention to specific features of a painting was not necessary for increasing the subjective aesthetic judgment when the artists’ commentary was presented. Our results suggest that at least two different cognitive mechanisms may be involved in knowledge- guided aesthetic judgments while viewers reappraise a painting. PMID:25945789

    2001-01-01

    Background Digital information technology can facilitate informed decision making by individuals regarding their personal health care. The digital divide separates those who do and those who do not have access to or otherwise make use of digital information. To close the digital divide, health care communications research must address a fundamental issue, the consumer vocabulary problem: consumers of health care, at least those who are laypersons, are not always familiar with the professional vocabulary and concepts used by providers of health care and by providers of health care information, and, conversely, health care and health care information providers are not always familiar with the vocabulary and concepts used by consumers. One way to address this problem is to develop a consumer entry vocabulary for health care communications. Objectives To evaluate the potential of controlled vocabulary resources for supporting the development of consumer entry vocabulary for diabetes. Methods We used folk medical terms from the Dictionary of American Regional English project to create exended versions of 3 controlled vocabulary resources: the Unified Medical Language System Metathesaurus, the Eurodicautom of the European Commission's Translation Service, and the European Commission Glossary of popular and technical medical terms. We extracted consumer terms from consumer-authored materials, and physician terms from physician-authored materials. We used our extended versions of the vocabulary resources to link diabetes-related terms used by health care consumers to synonymous, nearly-synonymous, or closely-related terms used by family physicians. We also examined whether retrieval of diabetes-related World Wide Web information sites maintained by nonprofit health care professional organizations, academic organizations, or governmental organizations can be improved by substituting a physician term for its related consumer term in the query.

    For the foreseeable future, controlled medical vocabularies will be in a constant state of development, expansion and refinement. Changes in controlled vocabularies must be reconciled with historical patient information which is coded using those vocabularies and stored in clinical databases. This paper explores the kinds of changes that can occur in controlled vocabularies, including adding terms (simple additions, refinements, redundancy and disambiguation), deleting terms, changing terms (major and minor name changes), and other special situations (obsolescence, discovering redundancy, and precoordination). Examples are drawn from actual changes appearing in the 1993 update to the International Classification of Diseases (ICD9-CM). The methods being used at Columbia-Presbyterian Medical Center to reconcile its Medical Entities Dictionary and its clinical database are discussed. PMID:7949906

  16. Assessing the language skills of children from culturally and linguistically diverse backgrounds: the expressive vocabulary performance of Singaporean English-Mandarin bilingual pre-schoolers.

    2012-06-01

    Standardized language assessments such as the Clinical Evaluation of Language Fundamentals Pre-school 2 United Kingdom (CELF Preschool 2 UK) are often used in speech-language pathology clinics to determine if a child is at risk of language difficulties. Many of these assessments are designed and standardized for use with monolingual Standard English-speaking children. It is thus recommended that these assessments should only be used with the populations they were designed for; if not test bias might result. However, such tests are still selected and used in the clinics of many multicultural and multilinguistic communities (e.g., Singapore). This research aimed to explore the performance of 79 Singaporean English-Mandarin pre-school children on the Expressive Vocabulary (EV) sub-test of the CELF Preschool 2 UK and to determine if their performance on the EV sub-test accurately reflected their language abilities by comparing their performance on a local screening language assessment tool, the Singapore English Action Picture Test (SEAPT). Results showed that local children performed poorly as compared to their UK counterparts. Two plausible reasons for the findings are: (1) the sub-test elicited only a single measure in English which ignored the language abilities of these bilingual children in their second language; and (2) the presence of culturally and linguistically biased test items.

  17. Mapping phonological information from auditory to written modality during foreign vocabulary learning.

    2008-12-01

    Learning to read in a foreign language often entails recognizing the printed form of words learned by sound. In the current study, the ability to map novel phonological information from the auditory modality onto the written modality was examined at different levels of overlap between the native language and an artificially constructed foreign language. In this study, monolingual English-speaking adults learned novel foreign words in the auditory modality. Recognition testing was first conducted in the auditory modality and then in the written modality. Participants who learned foreign words that matched English phonology showed similar accuracy rates when tested in either modality. Participants who learned foreign words that mismatched English phonology showed decreased recognition accuracy when tested in the written modality. Results indicate that cross-linguistic matching in phonology facilitated mapping of phonological information to the written modality. In addition, at different levels of cross-linguistic overlap, specific cognitive skills were found to correlate with the ability to map phonological information across modalities. This finding suggests that the cognitive skills required for acquisition of a foreign language may vary depending upon degree of cross-linguistic similarity.

    1996-11-01

    This document summarizes currently available information about the presence and significance of unexploded ordnance (UXO) in the two main areas of Aberdeen Proving Ground: Aberdeen Area and Edgewood Area. Known UXO in the land ranges of the Aberdeen Area consists entirely of conventional munitions. The Edgewood Area contains, in addition to conventional munitions, a significant quantity of chemical-munition UXO, which is reflected in the presence of chemical agent decomposition products in Edgewood Area ground-water samples. It may be concluded from current information that the UXO at Aberdeen Proving Ground has not adversely affected the environment through release of toxic substances to the public domain, especially not by water pathways, and is not likely to do so in the near future. Nevertheless, modest but periodic monitoring of groundwater and nearby surface waters would be a prudent policy.

    Forensic analysis of questioned documents sometimes can be extensively data intensive. A forensic expert might need to analyze a heap of document fragments and in such cases to ensure reliability he/she should focus only on relevant evidences hidden in those document fragments. Relevant document retrieval needs finding of similar document fragments. One notion of obtaining such similar documents could be by using document fragment's physical characteristics like color, texture, etc. In this article we propose an automatic scheme to retrieve similar document fragments based on visual appearance of document paper and texture. Multispectral color characteristics using biologically inspired color differentiation techniques are implemented here. This is done by projecting document color characteristics to Lab color space. Gabor filter-based texture analysis is used to identify document texture. It is desired that document fragments from same source will have similar color and texture. For clustering similar document fragments of our test dataset we use a Self Organizing Map (SOM) of dimension 5×5, where the document color and texture information are used as features. We obtained an encouraging accuracy of 97.17% from 1063 test images.

    Structured vocabulary development enhances the management of information in biological databases. As information grows, handling the complexity of vocabularies becomes difficult. Defined methods are needed to manipulate, expand and integrate complex vocabularies. The Gene Ontology (GO) project provides the scientific community with a set of structured vocabularies to describe domains of molecular biology. The vocabularies are used for annotation of gene products and for computational annotation of sequence data sets. The vocabularies focus on three concepts universal to living systems, biological process, molecular function and cellular component. As the vocabularies expand to incorporate terms needed by diverse annotation communities, species-specific terms become problematic. In particular, the use of species-specific anatomical concepts remains unresolved. We present a method for expansion of GO into areas outside of the three original universal concept domains. We combine concepts from two orthogonal vocabularies to generate a larger, more specific vocabulary. The example of mammalian heart development is presented because it addresses two issues that challenge GO; inclusion of organism-specific anatomical terms, and proliferation of terms and relationships. The combination of concepts from orthogonal vocabularies provides a robust representation of relevant terms and an opportunity for evaluation of hypothetical concepts. PMID:12466303

  3. Background Information on the Very Long Baseline Array

    NASA Astrophysics Data System (ADS)

    A continent-wide radio telescope system offering the greatest resolving power of any astronomical instrument operational today Overview: The National Science Foundation's VLBA is a system of ten identical radio-telescope antennas controlled from a common headquarters and working together as a single instrument. The radio signals received by each individual antenna contribute part of the information used to produce images of celestial objects with hundreds of times more detail than Hubble Space Telescope images. Scientific Areas: The VLBA can contribute to any astronomical research area where quality, high-resolution radio images will advance knowledge of the field. In its first five years of full operation, the VLBA has produced dramatic new information in these areas: * Stars: With the VLBA, astronomers have tracked gas motions in the atmosphere of a star other than the Sun for the first time; made the first maps of the magnetic field of a star other than the Sun; and studied the violent dances of double-star pairs in which one of the pair is a superdense neutron star or a black hole. * Protostars, star formation, and protoplanetary disks: The VLBA has provided scientists with some of the best views yet of very young stars and the complex regions in which they are born. VLBA images have shown outflows of gas from young stars and disks of material orbiting these new stars - material that later may form planetary systems. * Supernovae and Supernova Remnants: The VLBA has directly measured the expansion of a shell of exploded debris from the supernova SN 1993J, in the galaxy M81, some 11 million light-years from Earth. This has allowed scientists to learn new details about the explosion itself and its surroundings as well as calculate the distance to the supernova by using the VLBA data in conjunction with information from optical telescopes. VLBA images have shown regions of shocked gas in supernova remnants. * The Milky Way: Radio waves from extragalactic objects

  4. A harmonized vocabulary for soil observed properties

    NASA Astrophysics Data System (ADS)

    Simons, Bruce; Wilson, Peter; Cox, Simon; Vleeshouer, Jamie

    2014-05-01

    Interoperability of soil data depends on agreements concerning models, schemas and vocabularies. However, observed property terms are often defined during different activities and projects in isolation of one another, resulting in data that has the same scope being represented with different terms, using different formats and formalisms, and published in various access methods. Significantly, many soil property vocabularies conflate multiple concepts in a single term, e.g. quantity kind, units of measure, substance being observed, and procedure. Effectively, this bundles separate information elements into a single slot. We have developed a vocabulary for observed soil properties by adopting and extending a previously defined water quality vocabulary. The observed property model separates the information elements, based on the Open Geospatial Consortium (OGC) Observations & Measurements model and extending the NASA/TopQuadrant 'Quantities, Units, Dimensions and Types' (QUDT) ontology. The imported water quality vocabulary is formalized using the Web Ontology Language (OWL). Key elements are defined as sub-classes or sub-properties of standard Simple Knowledge Organization System (SKOS) elements, allowing use of standard vocabulary interfaces. For the soil observed property vocabulary, terms from QUDT and water quality are used where possible. These are supplemented with additional unit of measure (Unit), observed property (ScaledQuantityKind) and substance being observed (SubstanceOrTaxon) vocabulary entries required for the soil properties. The vocabulary terms have been extracted from the Australian Soil and Land Survey Field Handbook and Australian Soil Information Transfer and Evaluation System (SITES) vocabularies. The vocabulary links any chemical substances to items from the Chemical Entities of Biological Interest (ChEBI) ontology. By formalizing the model for observable properties, and clearly labelling the separate elements, soil property observations may

  5. Background Information: Deciphering Gamma Ray Burst Physics With Radio Telescopes

    NASA Astrophysics Data System (ADS)

    For 30 years, Gamma Ray Bursts, now known to be the most energetic explosions in the sky, have intrigued scientists and constituted one of the greatest mysteries in astrophysics. Such basic details as their exact locations in the sky and their distances from Earth remained unknown or subject to intense debate until just last year. With the discovery of "afterglows" at X-ray, visible, infrared and radio wavelengths, scientists have been able to study the physics of these explosive fireballs for the first time. Radio telescopes, the NSF's VLA in particular, are vitally important in this quest for the answers about Gamma Ray Bursts. Planned improvements to the VLA will make it an even more valuable tool in this field. Since their first identification in 1967 by satellites orbited to monitor compliance with the atmospheric nuclear test ban, more than 2,000 Gamma Ray Bursts have been detected. The celestial positions of the bursts have only been well-localized since early 1997, when the Italian- Dutch satellite Beppo-SAX went into operation. Since Beppo-SAX began providing improved information on burst positions, other instruments, both orbiting and ground-based, have been able to study the afterglows. So far, X-ray afterglows have been seen in about a dozen bursts, visible-light afterglows in six and radio afterglows in three. The search for radio emission from Gamma Ray Bursts has been an ongoing, target-of-opportunity program at the VLA for more than four years, led by NRAO scientist Dale Frail. The detection of afterglows "opens up a new era in the studies of Gamma Ray Bursts," Princeton University theorist Bohdan Paczynski wrote in a recent scientific paper. Optical studies of GRB 970508 indicated a distance of at least seven billion light-years, the first distance measured for a Gamma Ray Burst. VLA studies of the same burst showed that the fireball was about a tenth of a light-year in diameter a few days after the explosion and that it was expanding at very

SISSvoc3 differs from other SKOS-based vocabulary-access APIs such as GEMET [3] and NVS [4] in that (a) the service is decoupled from the content store, (b) the service URI is independent of the content URIs This means that a SISSvoc3 interface can be deployed over any SKOS vocabulary which is available at a SPARQL endpoint. As an example, a SISSvoc3 query and presentation interface has been deployed over the NERC vocabulary service hosted by the BODC, providing a search interface which is not available natively. We use vocabulary services to populate menus in user interfaces, to support data validation, and to configure data conversion routines. Related services built on LDA have also been used as a generic registry interface, and extended for serving gazetteer information.

    2014-05-01

    PEEX, as a long-term multidisciplinary integrated study, needs a systems design of a relevant information background. The idea of development of an Integrated Land Information System (ILIS) for the region as an initial step of future advanced integrated observing systems is considered as a promising way. The ILIS could serve (1) for introduction of a unified system of classification and quantification of environment, ecosystems and landscapes; (2) as a benchmark for tracing the dynamics of land use - land cover and ecosystems parameters, particularly for forests; (3) as a systems background for empirical assessment of indicators of an interest (e.g., components of biogeochemical cycles); (4) comparisons, harmonizing and mutual constraints of the results obtained by different methods; (5) for parameterization of surface fluxes for the 'atmosphere-land' system; (6) for use in divers models and for models' validation; (7) for downscaling of available information to a required scale; (8) for understanding of gradients for up-scaling of "point" data, etc. The ILIS is presented in form of multi-layer and multi-scale GIS that includes a hybrid land cover (HLC) by a definite date and corresponding legends and attributive databases. The HLC is based on relevant combination of a "multi" remote sensing concept that includes sensors of different type and resolution and ground data. The ILIS includes inter alia (1) general geographical and biophysical description of the territory (landscapes, soil, vegetation, hydrology, bioclimatic zones, permafrost etc.); (2) diverse datasets of measurements in situ; (3) sets of empirical and semi-empirical aggregation and auxiliary models, (4) data on different inventories and surveys (forest inventory, land account, results of forest monitoring); (5) spatial and temporal description of anthropogenic and natural disturbances; (5) climatic data with relevant temporal resolution etc. The ILIS should include only the data with known

    Ship detection based on video is important in the application of surveillance and marine safety, the detection results of tradition methods, such as background subtraction, have much noise because of background noise such as ocean wave. In this paper we present a simple but efficient method for ship detection, It is based on the edge information of single image and movement information of multi images. Firstly, detect those movement pixels used the background subtraction to the video image, and the distance transformation is operation on the difference images; Secondly, we detect the edge of video image used Canny detector , and morphological operation on the edge image, lastly, eliminate the movement pixels if their distance transformation value is bigger than the threshold. The experimental results demonstrate that is efficient to eliminate the background noise and detect the real target.

  11. Medical and Transmission Vector Vocabulary Alignment with Schema.org

    SciTech Connect

    Smith, William P.; Chappell, Alan R.; Corley, Courtney D.

    2015-04-21

    Available biomedical ontologies and knowledge bases currently lack formal and standards-based interconnections between disease, disease vector, and drug treatment vocabularies. The PNNL Medical Linked Dataset (PNNL-MLD) addresses this gap. This paper describes the PNNL-MLD, which provides a unified vocabulary and dataset of drug, disease, side effect, and vector transmission background information. Currently, the PNNL-MLD combines and curates data from the following research projects: DrugBank, DailyMed, Diseasome, DisGeNet, Wikipedia Infobox, Sider, and PharmGKB. The main outcomes of this effort are a dataset aligned to Schema.org, including a parsing framework, and extensible hooks ready for integration with selected medical ontologies. The PNNL-MLD enables researchers more quickly and easily to query distinct datasets. Future extensions to the PNNL-MLD will include Traditional Chinese Medicine, broader interlinks across genetic structures, a larger thesaurus of synonyms and hypernyms, explicit coding of diseases and drugs across research systems, and incorporating vector-borne transmission vocabularies.

  12. Fundamental Vocabulary Selection Based on Word Familiarity

    NASA Astrophysics Data System (ADS)

    Sato, Hiroshi; Kasahara, Kaname; Kanasugi, Tomoko; Amano, Shigeaki

    This paper proposes a new method for selecting fundamental vocabulary. We are presently constructing the Fundamental Vocabulary Knowledge-base of Japanese that contains integrated information on syntax, semantics and pragmatics, for the purposes of advanced natural language processing. This database mainly consists of a lexicon and a treebank: Lexeed (a Japanese Semantic Lexicon) and the Hinoki Treebank. Fundamental vocabulary selection is the first step in the construction of Lexeed. The vocabulary should include sufficient words to describe general concepts for self-expandability, and should not be prohibitively large to construct and maintain. There are two conventional methods for selecting fundamental vocabulary. The first is intuition-based selection by experts. This is the traditional method for making dictionaries. A weak point of this method is that the selection strongly depends on personal intuition. The second is corpus-based selection. This method is superior in objectivity to intuition-based selection, however, it is difficult to compile a sufficiently balanced corpora. We propose a psychologically-motivated selection method that adopts word familiarity as the selection criterion. Word familiarity is a rating that represents the familiarity of a word as a real number ranging from 1 (least familiar) to 7 (most familiar). We determined the word familiarity ratings statistically based on psychological experiments over 32 subjects. We selected about 30,000 words as the fundamental vocabulary, based on a minimum word familiarity threshold of 5. We also evaluated the vocabulary by comparing its word coverage with conventional intuition-based and corpus-based selection over dictionary definition sentences and novels, and demonstrated the superior coverage of our lexicon. Based on this, we conclude that the proposed method is superior to conventional methods for fundamental vocabulary selection.

  13. Vocabulary Knowledge of Deaf and Hearing Postsecondary Students

    Sarchet, Thomastine; Marschark, Marc; Borgna, Georgianna; Convertino, Carol; Sapere, Patricia; Dirmyer, Richard

    2014-01-01

    Deaf children generally are found to have smaller English vocabularies than hearing peers, although studies involving children with cochlear implants have suggested that the gap may decrease or disappear with age. Less is known about the vocabularies of deaf and hard-of-hearing (DHH) postsecondary students or how their vocabulary knowledge relates to other aspects of academic achievement. This study used the Peabody Picture Vocabulary Test to examine the vocabulary knowledge of DHH and hearing postsecondary students as well as their awareness (predictions) of that knowledge. Relationships between vocabulary knowledge and print exposure, communication backgrounds, and reading and verbal abilities also were examined. Consistent with studies of children, hearing college students demonstrated significantly larger vocabularies than DHH students both with and without cochlear implants. DHH students were more likely to overestimate their vocabulary knowledge. Vocabulary scores were positively related to reading and verbal abilities but negatively related to sign language abilities. Among DHH students they also were positively related to measures of spoken language ability. Results are discussed in terms of related cognitive abilities, language fluency, and academic achievement of DHH students and implications for postsecondary education. PMID:25558473

  17. A Neural Mechanism for Background Information-Gated Learning Based on Axonal-Dendritic Overlaps

    PubMed Central

    Mainetti, Matteo; Ascoli, Giorgio A.

    2015-01-01

    Experiencing certain events triggers the acquisition of new memories. Although necessary, however, actual experience is not sufficient for memory formation. One-trial learning is also gated by knowledge of appropriate background information to make sense of the experienced occurrence. Strong neurobiological evidence suggests that long-term memory storage involves formation of new synapses. On the short time scale, this form of structural plasticity requires that the axon of the pre-synaptic neuron be physically proximal to the dendrite of the post-synaptic neuron. We surmise that such “axonal-dendritic overlap” (ADO) constitutes the neural correlate of background information-gated (BIG) learning. The hypothesis is based on a fundamental neuroanatomical constraint: an axon must pass close to the dendrites that are near other neurons it contacts. The topographic organization of the mammalian cortex ensures that nearby neurons encode related information. Using neural network simulations, we demonstrate that ADO is a suitable mechanism for BIG learning. We model knowledge as associations between terms, concepts or indivisible units of thought via directed graphs. The simplest instantiation encodes each concept by single neurons. Results are then generalized to cell assemblies. The proposed mechanism results in learning real associations better than spurious co-occurrences, providing definitive cognitive advantages.

    2013-12-01

    In this paper we present a controlled vocabulary service application for Environmental Data Store (EDS). The purpose for such application is to help researchers and investigators to archive, manage, share, search, and retrieve data efficiently in EDS. The Simple Knowledge Organization System (SKOS) is used in the application for the representation of the controlled vocabularies coming from EDS. The controlled vocabularies of EDS are created by collecting, comparing, choosing and merging controlled vocabularies, taxonomies and ontologies widely used and recognized in geoscience/environmental informatics community, such as Environment ontology (EnvO), Semantic Web for Earth and Environmental Terminology (SWEET) ontology, CUAHSI Hydrologic Ontology and ODM Controlled Vocabulary, National Environmental Methods Index (NEMI), National Water Information System (NWIS) codes, EPSG Geodetic Parameter Data Set, WQX domain value etc. TemaTres, an open-source, web -based thesaurus management package is employed and extended to create and manage controlled vocabularies of EDS in the application. TemaTresView and VisualVocabulary that work well with TemaTres, are also integrated in the application to provide tree view and graphical view of the structure of vocabularies. The Open Source Edition of Virtuoso Universal Server is set up to provide a Web interface to make SPARQL queries against controlled vocabularies hosted on the Environmental Data Store. The replicas of some of the key vocabularies commonly used in the community, are also maintained as part of the application, such as General Multilingual Environmental Thesaurus (GEMET), NetCDF Climate and Forecast (CF) Standard Names, etc.. The application has now been deployed as an elementary and experimental prototype that provides management, search and download controlled vocabularies of EDS under SKOS framework.

  9. Imported malaria in Finland 2003-2011: prospective nationwide data with rechecked background information

    PubMed Central

    2013-01-01

    Background Although described in several reports, imported malaria in Europe has not been surveyed nationwide with overall coverage of patients and individually rechecked background information. Plasmodium falciparum infections have been reported despite regularly taken appropriate chemoprophylaxis, yet the reliability of such questionnaire-based retrospective data has been questioned. This was the starting-point for conducting a prospective nationwide survey of imported malaria where compliance data was double-checked. Methods Data was collected on all cases of imported malaria confirmed and recorded by the reference laboratory of Finland (population 5.4 million) from 2003 to 2011, and these were compared with those reported to the National Infectious Disease Register (NIDR). Background information was gathered by detailed questionnaires sent to the clinicians upon diagnosis; missing data were enquired by telephone of clinician or patient. Special attention was paid to compliance with chemoprophylaxis: self-reported use of anti-malarials was rechecked for all cases of P. falciparum. Results A total of 265 malaria cases (average annual incidence rate 0.5/100,000 population) had been recorded by the reference laboratory, all of them also reported to NIDR: 54% were born in malaria-endemic countries; 86% were currently living in non-endemic regions. Malaria was mainly (81%) contracted in sub-Saharan Africa. Plasmodium falciparum proved to be the most common species (72%). Immigrants constituted the largest group of travellers (44%). Pre-travel advice was received by 20% of those born in endemic regions and 81% of those from non-endemic regions. Of those with P. falciparum, 4% reported regular use of appropriate chemoprophylaxis (mefloquine or atovaquone/proguanil or doxycycline for regions with chloroquine-resistant and atovaquone/proguanil or doxycycline for regions with mefloquine-resistant P. falciparum); after individual rechecking, however, it was found that none

  16. Moving Controlled Vocabularies into the Semantic Web

    NASA Astrophysics Data System (ADS)

    Thomas, R.; Lowry, R. K.; Kokkinaki, A.

    2015-12-01

    One of the issues with legacy oceanographic data formats is that the only tool available for describing what a measurement is and how it was made is a single metadata tag known as the parameter code. The British Oceanographic Data Centre (BODC) has been supporting the international oceanographic community gain maximum benefit from this through a controlled vocabulary known as the BODC Parameter Usage Vocabulary (PUV). Over time this has grown to over 34,000 entries some of which have preferred labels with over 400 bytes of descriptive information detailing what was measured and how. A decade ago the BODC pioneered making this information available in a more useful form with the implementation of a prototype vocabulary server (NVS) that referenced each 'parameter code' as a URL. This developed into the current server (NVS V2) in which the parameter URL resolves into an RDF document based on the SKOS data model which includes a list of resource URLs mapped to the 'parameter'. For example the parameter code for a contaminant in biota, such as 'cadmium in Mytilus edulis', carries RDF triples leading to the entry for Mytilus edulis in the WoRMS and for cadmium in the ChEBI ontologies. By providing links into these external ontologies the information captured in a 1980s parameter code now conforms to the Linked Data paradigm of the Semantic Web, vastly increasing the descriptive information accessible to a user. This presentation will describe the next steps along the road to the Semantic Web with the development of a SPARQL end point1 to expose the PUV plus the 190 other controlled vocabularies held in NVS. Whilst this is ideal for those fluent in SPARQL, most users require something a little more user-friendly and so the NVS browser2 was developed over the end point to allow less technical users to query the vocabularies and navigate the NVS ontology. This tool integrates into an editor that allows vocabulary content to be manipulated by authorised users outside BODC

  17. The Cryogenic Dark Matter Search and Background Rejection with Event Position Information

    SciTech Connect

    Wang, Gensheng

    2005-01-01

    Evidence from observational cosmology and astrophysics indicates that about one third of the universe is matter, but that the known baryonic matter only contributes to the universe at 4%. A large fraction of the universe is cold and non-baryonic matter, which has important role in the universe structure formation and its evolution. The leading candidate for the non-baryonic dark matter is Weakly Interacting Massive Particles (WIMPs), which naturally occurs in the supersymmetry theory in particle physics. The Cryogenic Dark Matter Search (CDMS) experiment is searching for evidence of a WIMP interaction off an atomic nucleus in crystals of Ge and Si by measuring simultaneously the phonon energy and ionization energy of the interaction in the CDMS detectors. The WIMP interaction energy is from a few keV to tens of keV with a rate less than 0.1 events/kg/day. To reach the goal of WIMP detection, the CDMS experiment has been conducted in the Soudan mine with an active muon veto and multistage passive background shields. The CDMS detectors have a low energy threshold and background rejection capabilities based on ionization yield. However, betas from contamination and other radioactive sources produce surface interactions, which have low ionization yield, comparable to that of bulk nuclear interactions. The low-ionization surface electron recoils must be removed in the WIMP search data analysis. An emphasis of this thesis is on developing the method of the surface-interaction rejection using location information of the interactions, phonon energy distributions and phonon timing parameters. The result of the CDMS Soudan run118 92.3 live day WIMP search data analysis is presented, and represents the most sensitive search yet performed.

  5. Using probe secondary structure information to enhance Affymetrix GeneChip background estimates

    PubMed Central

    Gharaibeh, Raad Z.; Fodor, Anthony A.; Gibas, Cynthia J.

    2007-01-01

    High-density short oligonucleotide microarrays are a primary research tool for assessing global gene expression. Background noise on microarrays comprises a significant portion of the measured raw data. A number of statistical techniques have been developed to correct for this background noise. Here, we demonstrate that probe minimum folding energy and structure can be used to enhance a previously existing model for background noise correction. We estimate that probe secondary structure accounts for up to 3% of all variation on Affymetrix microarrays. PMID:17387043

    2009-12-01

    The implementation of traceability in the food supply chain has reinforced adoption of technologies with the ability to track forward and trace back product-related information. Based on the premise that these technologies can be used as a means to provide product-related information to consumers, this paper explores the perceived benefits and drawbacks of such technologies. The aim is to identify factors that influence consumers' perceptions of such technologies, and furthermore to advise the agri-food business on issues that they should consider prior to the implementation of such technologies in their production lines. For the purposes of the study, a focus group study was conducted across 12 European countries, while a set of four different technologies used as a means to provide traceability information to consumers was the focal point of the discussions in each focus group. Results show that the amount of and confidence in the information provided, perceived levels of convenience, impact on product quality and safety, impact on consumers' health and the environment, and potential consequences on ethical and privacy liberties constitute important factors influencing consumers' perceptions of technologies that provide traceability.

    Sutter, S. L.

    1982-05-01

    Safety assessments and environmental impact statements for nuclear fuel cycle facilities require an estimate of the amount of radioactive particulate material initially airborne (source term) during accidents. Pacific Northwest Laboratory (PNL) has surveyed the literature, gathering information on the amount and size of these particles that has been developed from limited experimental work, measurements made from operational accidents, and known aerosol behavior. Information useful for calculating both liquid and powder source terms is compiled in this report. Potential aerosol generating events discussed are spills, resuspension, aerodynamic entrainment, explosions and pressurized releases, comminution, and airborne chemical reactions. A discussion of liquid behavior in sprays, sparging, evaporation, and condensation as applied to accident situations is also included.

  1. Enhanced Community Structure Detection in Complex Networks with Partial Background Information

    PubMed Central

    Zhang, Zhong-Yuan; Sun, Kai-Di; Wang, Si-Qi

    2013-01-01

    Community structure detection in complex networks is important since it can help better understand the network topology and how the network works. However, there is still not a clear and widely-accepted definition of community structure, and in practice, different models may give very different results of communities, making it hard to explain the results. In this paper, different from the traditional methodologies, we design an enhanced semi-supervised learning framework for community detection, which can effectively incorporate the available prior information to guide the detection process and can make the results more explainable. By logical inference, the prior information is more fully utilized. The experiments on both the synthetic and the real-world networks confirm the effectiveness of the framework. PMID:24247657

  2. 25 Years of Controlled Vocabularies in Oceanographic Data Management

    NASA Astrophysics Data System (ADS)

    Lowry, R. K.

    2008-12-01

    In the 1980s data managers in IOC realised that data exchange required a common terminology for concepts such as parameters, instruments and platforms. They rose to the challenge by developing a set of 7 controlled vocabularies that were published in print as part of the GF3 standard in 1987. Unfortunately, because this was based on print, the vocabularies couldn't be maintained and were little used. However, in the 1990s the pan-European SeaSearch project developed them into a usable digital vocabulary library. Whilst this was a significant step forward, vocabulary content governance was delegated to individuals, technical governance procedures were far from watertight and the terms had no definitions. Consequently, usage problems, especially local copy evolution and term misunderstandings persisted. When SeaDataNet started in 2006 there was a determination to use technology to solve these problems. Now, list server content governance harnesses domain expertise, relational database technology provides robust, scalable, versioned storage and the NERC DataGrid SOAP and pseudo-RESTful Web Service APIs serve lists and mappings. The SeaDataNet vocabulary technology currently addresses two use cases: semantic cross-walking and metadata field content verification. Basic metadata cross-walks do not transfer fields populated from different vocabularies, thereby losing information, because machine-accessible translations are unavailable. In SeaDataNet we have assembled mappings between lists of interest, particularly parameter vocabularies, into an RDF triple store. The resulting ontology is served as RDF documents through API method calls and term URLs. Metadata content verification is implemented by embedding URNs into documents defined by Schematron- extended schemas that are automatically built by a service monitoring the vocabulary server for content changes. These schemas allow generic XML editors, such as Oxygen, to validate document semantic content against the

  4. Surveys for presence of Oregon spotted frog (Rana pretiosa): background information and field methods

    USGS Publications Warehouse

    Pearl, Christopher A.; Clayton, David; Turner, Lauri

    2010-01-01

    The Oregon spotted frog (Rana pretiosa) is the most aquatic of the native frogs in the Pacific Northwest. The common name derives from the pattern of black, ragged-edged spots set against a brown or red ground color on the dorsum of adult frogs. Oregon spotted frogs are generally associated with wetland complexes that have several aquatic habitat types and sizeable coverage of emergent vegetation. Like other ranid frogs native to the Northwest, Oregon spotted frogs breed in spring, larvae transform in summer of their breeding year, and adults tend to be relatively short lived (3-5 yrs). Each life stage (egg, tadpole, juvenile and adult) has characteristics that present challenges for detection. Breeding can be explosive and completed within 1-2 weeks. Egg masses are laid in aggregations, often in a few locations in large areas of potential habitat. Egg masses can develop, hatch, and disintegrate in <2 weeks during warm weather. Tadpoles can be difficult to identify, have low survival, and spend most of their 3-4 months hidden in vegetation or flocculant substrates. Juveniles and adults are often difficult to capture and can spend summers away from breeding areas. Moreover, a substantial portion of extant populations are of limited size (<100 breeding adults), and field densities of all life stages are often low. An understanding of the biology of the species and use of multiple visits are thus important for assessing presence of Oregon spotted frogs. This report is meant to be a resource for USDA Region 6 Forest Service (FS) and OR/WA Bureau of Land Management (BLM) personnel tasked with surveying for the presence of Oregon spotted frogs. Our objective was to summarize information to improve the efficiency of field surveys and increase chances of detection if frogs are present. We include overviews of historical and extant ranges of Oregon spotted frog. We briefly summarize what is known of Oregon spotted frog habitat associations and review aspects of behavior and

    2006-01-01

    Laypersons (“consumers”) often have difficulty finding, understanding, and acting on health information due to gaps in their domain knowledge. Ideally, consumer health vocabularies (CHVs) would reflect the different ways consumers express and think about health topics, helping to bridge this vocabulary gap. However, despite the recent research on mismatches between consumer and professional language (e.g., lexical, semantic, and explanatory), there have been few systematic efforts to develop and evaluate CHVs. This paper presents the point of view that CHV development is practical and necessary for extending research on informatics-based tools to facilitate consumer health information seeking, retrieval, and understanding. In support of the view, we briefly describe a distributed, bottom-up approach for (1) exploring the relationship between common consumer health expressions and professional concepts and (2) developing an open-access, preliminary (draft) “first-generation” CHV. While recognizing the limitations of the approach (e.g., not addressing psychosocial and cultural factors), we suggest that such exploratory research and development will yield insights into the nature of consumer health expressions and assist developers in creating tools and applications to support consumer health information seeking.

    2008-12-01

    One of the greatest challenges facing augmentative and alternative communication (AAC) professionals is providing children with complex communication needs with access to the vocabulary that they need in order to develop mature language and literacy abilities. The purpose of this study was to analyze the vocabulary used by typically developing early-elementary children in the United States and New Zealand when they write about self-selected topics, in order to inform practices with children with complex communication needs. The children's writing samples were compared across school ages and countries. The school age comparisons highlighted the relatively restricted range of vocabulary used by children in the earliest stages of writing development, and the country comparisons revealed differences in core vocabulary. The findings of this study hopefully will assist AAC professionals as they engage in selecting, prioritizing, and organizing vocabulary to support written language development in children with complex communication needs.

    Infrared moving small target detection under complex cloud backgrounds is one of the key techniques of infrared search and track (IRST) systems. This paper proposes a novel method based on in-frame inter-frame information to detect infrared moving small targets accurately. For a single frame, in the spatial domain, a directional max-median filter is developed to make a pre-processing and a background suppression filtering template is utilized on the denoised image to highlight target. Then, targets in cloud regions and non-cloud regions are extracted by different thresholds according to a cloud discrimination method so that a spatial domain map (SDM) is acquired. In the frequency domain, we design an α-DoB band-pass filter to conduct coarse saliency detection and make an amplitude transformation with smoothing processing which is the so-called elaborate saliency detection. Furthermore, a frequency domain map (FDM) is acquired by an adaptive binary segmentation method. Lastly, candidate targets in single frame are extracted by a discrimination based on intensity and spatial distance criteria. For consecutive frames, a false alarm suppression is conducted on account of differences of motion features between moving target and false alarms to improve detection accuracy again. Large numbers of experiments demonstrate that the proposed method has satisfying detection effectiveness and robustness for infrared moving small target detection under complex cloud backgrounds.

    2014-01-01

    Purpose Vocabulary is a domain of particular challenge for many children with autism spectrum disorder (ASD). Recent research has drawn attention to ways in which lexical characteristics relate to vocabulary acquisition. The current study tested the hypothesis that lexical characteristics account for variability in vocabulary size of young children with ASD, applying the Extended Statistical Learning theory of vocabulary delay in late talkers (Stokes, Kern, & dos Santos, 2012) to toddlers with ASD. Method Parents reported the words produced by toddlers with ASD (n=57; ages 21–37 months) or toddlers without ASD (n=41; ages 22–26 months) on the MacArthur-Bates Communicative Development Inventories. The average phonological neighborhood density, word frequency, and word length of each toddler’s lexicon was calculated. These lexical characteristics served as predictors of vocabulary size. Results Findings differed for toddlers with and without ASD and according to subsamples. Vocabulary size was predicted by word length for toddlers with ASD and by phonological neighborhood density for toddlers without ASD. Conclusions Distinct relationships between lexical characteristics and vocabulary size were observed for toddlers with and without ASD. Experimental studies on distributional cues to vocabulary acquisition are needed to inform what is known about mechanisms of learning in neurodevelopmental disorders. PMID:24687027

    Approaches for the analysis and specification of business vocabularies and rules are very relevant topics in both Business Process Management and Information Systems Development disciplines. However, in common practice of Information Systems Development, the Business modeling activities still are of mostly empiric nature. In this paper, basic aspects of the approach for business vocabularies' semi-automated extraction from business process models are presented. The approach is based on novel business modeling-level OMG standards "Business Process Model and Notation" (BPMN) and "Semantics for Business Vocabularies and Business Rules" (SBVR), thus contributing to OMG's vision about Model-Driven Architecture (MDA) and to model-driven development in general.

  14. New concepts for building vocabulary for cell image ontologies

    PubMed Central

    2011-01-01

    Background There are significant challenges associated with the building of ontologies for cell biology experiments including the large numbers of terms and their synonyms. These challenges make it difficult to simultaneously query data from multiple experiments or ontologies. If vocabulary terms were consistently used and reused across and within ontologies, queries would be possible through shared terms. One approach to achieving this is to strictly control the terms used in ontologies in the form of a pre-defined schema, but this approach limits the individual researcher's ability to create new terms when needed to describe new experiments. Results Here, we propose the use of a limited number of highly reusable common root terms, and rules for an experimentalist to locally expand terms by adding more specific terms under more general root terms to form specific new vocabulary hierarchies that can be used to build ontologies. We illustrate the application of the method to build vocabularies and a prototype database for cell images that uses a visual data-tree of terms to facilitate sophisticated queries based on a experimental parameters. We demonstrate how the terminology might be extended by adding new vocabulary terms into the hierarchy of terms in an evolving process. In this approach, image data and metadata are handled separately, so we also describe a robust file-naming scheme to unambiguously identify image and other files associated with each metadata value. The prototype database http://sbd.nist.gov/ consists of more than 2000 images of cells and benchmark materials, and 163 metadata terms that describe experimental details, including many details about cell culture and handling. Image files of interest can be retrieved, and their data can be compared, by choosing one or more relevant metadata values as search terms. Metadata values for any dataset can be compared with corresponding values of another dataset through logical operations. Conclusions

  15. Planned NLM/AHCPR large-scale vocabulary test: using UMLS technology to determine the extent to which controlled vocabularies cover terminology needed for health care and public health.

    1996-01-01

    The National Library of Medicine (NLM) and the Agency for Health Care Policy and Research (AHCPR) are sponsoring a test to determine the extent to which a combination of existing health-related terminologies covers vocabulary needed in health information systems. The test vocabularies are the 30 that are fully or partially represented in the 1996 edition of the Unified Medical Language System (UMLS) Metathesaurus, plus three planned additions: the portions of SNOMED International not in the 1996 Metathesaurus Read Clinical Classification, and the Logical Observations Identifiers, Names, and Codes (LOINC) system. These vocabularies are available to testers through a special interface to the Internet-based UMLS Knowledge Source Server. The test will determine the ability of the test vocabularies to serve as a source of controlled vocabulary for health data systems and applications. It should provide the basis for realistic resource estimates for developing and maintaining a comprehensive "standard" health vocabulary that is based on existing terminologies. PMID:8816351

  16. How vocabulary size in two languages relates to efficiency in spoken word recognition by young Spanish-English bilinguals

    PubMed Central

    Marchman, Virginia A.; Fernald, Anne; Hurtado, Nereyda

    2010-01-01

    Research using online comprehension measures with monolingual children shows that speed and accuracy of spoken word recognition are correlated with lexical development. Here we examined speech processing efficiency in relation to vocabulary development in bilingual children learning both Spanish and English (n=26; 2;6 yrs). Between-language associations were weak: vocabulary size in Spanish was uncorrelated with vocabulary in English, and children’s facility in online comprehension in Spanish was unrelated to their facility in English. Instead, efficiency of online processing in one language was significantly related to vocabulary size in that language, after controlling for processing speed and vocabulary size in the other language. These links between efficiency of lexical access and vocabulary knowledge in bilinguals parallel those previously reported for Spanish and English monolinguals, suggesting that children’s ability to abstract information from the input in building a working lexicon relates fundamentally to mechanisms underlying the construction of language.

    Interest (ChEBI). ChEBI is an OWL-based dictionary of over 70 000 molecular entities, based on existing scientific work and linked through to International Union of Pure and Applied Chemistry (IUPAC) Nomenclature. Within the model the relevant classes, including those from QUDT, are declared to be subclasses of SKOS Concept, so the resulting vocabularies may be directly mapped to other SKOS-based vocabularies, such as from the NERC Vocabulary Service or the Marine Metadata Initiative, using SKOS predicates. Where the external vocabularies are not published with persistent URIs, such as CUAHSI, the mapping may be recorded more informally using annotations, or use proxy URIs for the external vocabulary. The resulting SKOS vocabularies demonstrate a separation of governance of key definitions such as units and quantities and chemical entities, ensuring reuse where possible and extending and adding detail where necessary.

  2. Background Error Covariance Estimation Using Information from a Single Model Trajectory with Application to Ocean Data Assimilation

    NASA Technical Reports Server (NTRS)

    Keppenne, Christian L.; Rienecker, Michele; Kovach, Robin M.; Vernieres, Guillaume

    2014-01-01

    An attractive property of ensemble data assimilation methods is that they provide flow dependent background error covariance estimates which can be used to update fields of observed variables as well as fields of unobserved model variables. Two methods to estimate background error covariances are introduced which share the above property with ensemble data assimilation methods but do not involve the integration of multiple model trajectories. Instead, all the necessary covariance information is obtained from a single model integration. The Space Adaptive Forecast error Estimation (SAFE) algorithm estimates error covariances from the spatial distribution of model variables within a single state vector. The Flow Adaptive error Statistics from a Time series (FAST) method constructs an ensemble sampled from a moving window along a model trajectory.SAFE and FAST are applied to the assimilation of Argo temperature profiles into version 4.1 of the Modular Ocean Model (MOM4.1) coupled to the GEOS-5 atmospheric model and to the CICE sea ice model. The results are validated against unassimilated Argo salinity data. They show that SAFE and FAST are competitive with the ensemble optimal interpolation (EnOI) used by the Global Modeling and Assimilation Office (GMAO) to produce its ocean analysis. Because of their reduced cost, SAFE and FAST hold promise for high-resolution data assimilation applications.

  3. A tool for sharing annotated research data: the "Category 0" UMLS (Unified Medical Language System) vocabularies

    PubMed Central

    Berman, Jules J

    2003-01-01

    Background Large biomedical data sets have become increasingly important resources for medical researchers. Modern biomedical data sets are annotated with standard terms to describe the data and to support data linking between databases. The largest curated listing of biomedical terms is the the National Library of Medicine's Unified Medical Language System (UMLS). The UMLS contains more than 2 million biomedical terms collected from nearly 100 medical vocabularies. Many of the vocabularies contained in the UMLS carry restrictions on their use, making it impossible to share or distribute UMLS-annotated research data. However, a subset of the UMLS vocabularies, designated Category 0 by UMLS, can be used to annotate and share data sets without violating the UMLS License Agreement. Methods The UMLS Category 0 vocabularies can be extracted from the parent UMLS metathesaurus using a Perl script supplied with this article. There are 43 Category 0 vocabularies that can be used freely for research purposes without violating the UMLS License Agreement. Among the Category 0 vocabularies are: MESH (Medical Subject Headings), NCBI (National Center for Bioinformatics) Taxonomy and ICD-9-CM (International Classification of Diseases-9-Clinical Modifiers). Results The extraction file containing all Category 0 terms and concepts is 72,581,138 bytes in length and contains 1,029,161 terms. The UMLS Metathesaurus MRCON file (January, 2003) is 151,048,493 bytes in length and contains 2,146,899 terms. Therefore the Category 0 vocabularies, in aggregate, are about half the size of the UMLS metathesaurus. A large publicly available listing of 567,921 different medical phrases were automatically coded using the full UMLS metatathesaurus and the Category 0 vocabularies. There were 545,321 phrases with one or more matches against UMLS terms while 468,785 phrases had one or more matches against the Category 0 terms. This indicates that when the two vocabularies are evaluated by their fitness

    2010-05-01

    In this paper we introduce a comprehensive database of the vocabulary in reading materials used by 5 - 9 year old children in the UK. The database is available on-line http://www.essex.ac.uk/psychology/cpwd and allows researchers into early reading development the possibility of rigorous control over critical characteristics of experimental stimuli such as word frequency, regularity and length, frequency of grapheme-phoneme correspondences, orthographic and phonological neighbourhoods etc. The on-line database is also a resource that can be used by practitioners with interests in literacy development and literacy instruction. It can be used to obtain characteristics for a user-generated list of words, or else to generate a list of words according to constraints specified by the user. Here we present an overview of the construction of the database, the materials entered into it, the survey of schools by which we obtained information about the books that were most likely to be used by children in each age group, and the search features available on the database website. We also discuss certain characteristics of the Vocabulary itself and compare these with those reported in an earlier non-representative database reported in Stuart, Dixon, Masterson and Gray (2003). We then present a detailed analysis of the characteristics of Vocabulary in books used in the Reception year, against the background of recent recommendations for change in the early teaching of reading. Finally, we present data showing that the database is indeed already proving a useful resource for both practitioners and researchers.

    2015-01-01

    What role does attention to different object properties play in early vocabulary development? This longitudinal study using event-related potentials in combination with behavioral measures investigated 20- and 24-month-olds' (n = 38; n = 34; overlapping n = 24) ability to use object shape and object part information in word-object mapping. The N400 component was used to measure semantic priming by images containing shape or detail information. At 20 months, the N400 to words primed by object shape varied in topography and amplitude depending on vocabulary size, and these differences predicted productive vocabulary size at 24 months. At 24 months, when most of the children had vocabularies of several hundred words, the relation between vocabulary size and the N400 effect in a shape context was weaker. Detached object parts did not function as word primes regardless of age or vocabulary size, although the part-objects were identified behaviorally. The behavioral measure, however, also showed relatively poor recognition of the part-objects compared to the shape-objects. These three findings provide new support for the link between shape recognition and early vocabulary development. PMID:25762957

    2008-02-01

    This study sought to determine why American parents from different socioeconomic backgrounds communicate in different ways with their children. Forty-seven parent-child dyads were videotaped engaging in naturalistic interactions in the home for ninety minutes at child age 2;6. Transcripts of these interactions provided measures of child-directed speech. Children's vocabulary comprehension skills were measured using the Peabody Picture Vocabulary Test at 2;6 and one year later at 3;6. Results indicate that: (I) child-directed speech with toddlers aged 2;6 predicts child vocabulary skill one year later, controlling for earlier toddler vocabulary skill; (2) child-directed speech relates to socioeconomic status as measured by income and education; and (3) the relation between socioeconomic status and child-directed speech is mediated by parental knowledge of child development. Potential mechanisms through which parental knowledge influences communicative behavior are discussed.

    This study examined younger (n = 16) and older (n = 16) listeners' processing of dysarthric speech-a naturally occurring form of signal degradation. It aimed to determine how age, hearing acuity, memory, and vocabulary knowledge interacted in speech recognition and lexical segmentation. Listener transcripts were coded for accuracy and pattern of lexical boundary errors. For younger listeners, transcription accuracy was predicted by receptive vocabulary. For older listeners, this same effect existed but was moderated by pure-tone hearing thresholds. While both groups employed syllabic stress cues to inform lexical segmentation, older listeners were less reliant on this perceptual strategy. The results were interpreted to suggest that individuals with larger receptive vocabularies, with their presumed greater language familiarity, were better able to leverage cue redundancies within the speech signal to form lexical hypothesis-leading to an improved ability to comprehend dysarthric speech. This advantage was minimized as hearing thresholds increased. While the differing levels of reliance on stress cues across the listener groups could not be attributed to specific individual differences, it was hypothesized that some combination of larger vocabularies and reduced hearing thresholds in the older participant group led to them prioritize lexical cues as a segmentation frame.

  9. Rat Strain Ontology: structured controlled vocabulary designed to facilitate access to strain data at RGD

    PubMed Central

    2013-01-01

    Background The Rat Genome Database (RGD) ( http://rgd.mcw.edu/) is the premier site for comprehensive data on the different strains of the laboratory rat (Rattus norvegicus). The strain data are collected from various publications, direct submissions from individual researchers, and rat providers worldwide. Rat strain, substrain designation and nomenclature follow the Guidelines for Nomenclature of Mouse and Rat Strains, instituted by the International Committee on Standardized Genetic Nomenclature for Mice. While symbols and names aid in identifying strains correctly, the flat nature of this information prohibits easy search and retrieval, as well as other data mining functions. In order to improve these functionalities, particularly in ontology-based tools, the Rat Strain Ontology (RS) was developed. Results The Rat Strain Ontology (RS) reflects the breeding history, parental background, and genetic manipulation of rat strains. This controlled vocabulary organizes strains by type: inbred, outbred, chromosome altered, congenic, mutant and so on. In addition, under the chromosome altered category, strains are organized by chromosome, and further by type of manipulations, such as mutant or congenic. This allows users to easily retrieve strains of interest with modifications in specific genomic regions. The ontology was developed using the Open Biological and Biomedical Ontology (OBO) file format, and is organized on the Directed Acyclic Graph (DAG) structure. Rat Strain Ontology IDs are included as part of the strain report (RS: ######). Conclusions As rat researchers are often unaware of the number of substrains or altered strains within a breeding line, this vocabulary now provides an easy way to retrieve all substrains and accompanying information. Its usefulness is particularly evident in tools such as the PhenoMiner at RGD, where users can now easily retrieve phenotype measurement data for related strains, strains with similar backgrounds or those with similar

  10. Measuring bilingual children's receptive vocabularies.

    PubMed

    Umbel, V M; Pearson, B Z; Fernández, M C; Oller, D K

    1992-08-01

    Receptive vocabulary of Hispanic children in Miami was tested in both English and Spanish with complementary standardized tests, the Peabody Picture Vocabulary Test (PPVT-R) and the Test de Vocabulario en Imágenes Peabody (TVIP-H). 105 bilingual first graders, of middle to high socioeconomic status relative to national norms, were divided according to the language(s) spoken in their homes. Both groups, whether they spoke only Spanish in the home (OSH) or both English and Spanish in the home (ESH), performed near the mean of 100 in Spanish receptive vocabulary (TVIP-H means 97.0 and 96.5); in contrast, ESH group children scored more than 1 SD higher in English than OSH group children (PPVT-R means 88.0 and 69.7, respectively). It appears, therefore, that learning 2 languages at once does not harm receptive language development in the language of origin, while it does lay the groundwork for superior performance in the majority language. Furthermore, an analysis of translation equivalents, items shared by both tests, shows that a statistically significant portion of bilingual children's lexical knowledge does not overlap in their 2 languages and is therefore not reflected in single-language scores.

    In the spring of 2013 the U.S. White House by executive order mandated: “Government information shall be managed as an asset throughout its life cycle to promote interoperability and openness, and, wherever possible and legally permissible, to ensure that data are released to the public in ways that make the data easy to find, accessible, and usable.” Key for the reusability of any scientific data is hereby the availability of metadata describing the published data in a vocabulary that is familiar to its potential users. The objective of this paper is to help scientific application developers who want to adopt the continuous stream of new community vocabularies to help make their data sharable, self-describable, and easily understood. To achieve this we suggest semantic vocabulary and application integration best practices and discuss the tradeoffs of encoding vocabularies through code versus deriving code from vocabularies.

  9. Risk factors for children's receptive vocabulary development from four to eight years in the longitudinal study of Australian children.

    PubMed

    Taylor, Catherine L; Christensen, Daniel; Lawrence, David; Mitrou, Francis; Zubrick, Stephen R

    2013-01-01

    Receptive vocabulary develops rapidly in early childhood and builds the foundation for language acquisition and literacy. Variation in receptive vocabulary ability is associated with variation in children's school achievement, and low receptive vocabulary ability is a risk factor for under-achievement at school. In this study, bivariate and multivariate growth curve modelling was used to estimate trajectories of receptive vocabulary development in relation to a wide range of candidate child, maternal and family level influences on receptive vocabulary development from 4-8 years. The study sample comprised 4332 children from the first nationally representative Longitudinal Study of Australian Children (LSAC). Predictors were modeled as risk variables with the lowest level of risk as the reference category. In the multivariate model, risks for receptive vocabulary delay at 4 years, in order of magnitude, were: Maternal Non- English Speaking Background (NESB), low school readiness, child not read to at home, four or more siblings, low family income, low birthweight, low maternal education, maternal mental health distress, low maternal parenting consistency, and high child temperament reactivity. None of these risks were associated with a lower rate of growth from 4-8 years. Instead, maternal NESB, low school readiness and maternal mental health distress were associated with a higher rate of growth, although not sufficient to close the receptive vocabulary gap for children with and without these risks at 8 years. Socio-economic area disadvantage, was not a risk for low receptive vocabulary ability at 4 years but was the only risk associated with a lower rate of growth in receptive vocabulary ability. At 8 years, the gap between children with and without socio-economic area disadvantage was equivalent to eight months of receptive vocabulary growth. These results are consistent with other studies that have shown that social gradients in children's developmental outcomes

    2012-06-26

    Corrective Action Site (CAS) 02-37-02, Gas Sampling Assembly, is associated with nuclear test MULLET. MULLET was an underground safety test conducted on October 17, 1963. The experiment also involved prompt sampling of particulate material from the detonation, similar to CAS 09-99-06, Gas Sampling Assembly, which is associated with PLAYER/YORK. The sampling system at MULLET was similar to that of PLAYER/YORK and was used to convey gas from the MULLET emplacement hole (U2ag) to a sampling assembly. Beyond the sampling assembly, the system had a 'Y' junction with one branch running to a filter unit and the other running to a scrubber unit. The total system length was approximately 250 feet and is depicted on the attached drawing. According to the available background information, retrieval of the sample material from the MULLET event caused significant alpha (plutonium) contamination, limited to an area near ground zero (GZ). Test support Radiological Control Technicians did not detect contamination outside the immediate GZ area. In addition, vehicles, equipment, and workers that were contaminated were decontaminated on site. Soil contamination was addressed through the application of oil, and the site was decommissioned after the test. Any equipment that could be successfully decontaminated and had a future use was removed from the site. The contaminated equipment and temporary buildings erected to support the test were buried on site, most likely in the area under the dirt berm. The exact location of the buried equipment and temporary buildings is unknown. No information was found describing the disposition of the filter and scrubber, but they are not known to be at the site. The COMMODORE test was conducted at U2am on May 20, 1967, and formed the crater next to CAS 02-37-02. The COMMODORE test area had been surveyed prior to the test, and alpha contamination was not identified. Furthermore, alpha contamination was not identified during the COMMODORE re

    Bjork, Robert A; Kroll, Judith F

    2015-01-01

    In this article we discuss the role of desirable difficulties in vocabulary learning from two perspectives, one having to do with identifying conditions of learning that impose initial challenges to the learner but then benefit later retention and transfer, and the other having to do with the role of certain difficulties that are intrinsic to language processes, are engaged during word learning, and reflect how language is understood and produced. From each perspective we discuss evidence that supports the notion that difficulties in learning and imposed costs to language processing may produce benefits because they are likely to increase conceptual understanding. We then consider the consequences of these processes for actual second-language learning and suggest that some of the domain-general cognitive advantages that have been reported for proficient bilinguals may reflect difficulties imposed by the learning process, and by the requirement to negotiate cross-language competition, that are broadly desirable. As Alice Healy and her collaborators were perhaps the first to demonstrate, research on desirable difficulties in vocabulary and language learning holds the promise of bringing together research traditions on memory and language that have much to offer each other.

    The concept of a cockpit display of traffic information (CDTI) includes the integration of air traffic, navigation, and other pertinent information in a single electronic display in the cockpit. Concise display symbology was developed for use in later full-mission simulator evaluations of the CDTI concept. Experimental variables used included the update interval motion of the aircraft, the update type, (that is, whether the two aircraft were updated at the same update interval or not), the background (grid pattern or no background), and encounter type (straight or curved). Only the type of encounter affected performance.

  20. The reciprocal relationship between compounding awareness and vocabulary knowledge in Chinese: a latent growth model study

    PubMed Central

    Cheng, Yahua; Li, Liping; Wu, Xinchun

    2015-01-01

    The aim of this study is to examine the developmental relationship between compounding awareness and vocabulary knowledge from grades 1 to 2 in Chinese children. In this study, 149 Chinese children were tested on compounding awareness and vocabulary knowledge from Time 1 to Time 4, with non-verbal IQ, working memory, phonological awareness, orthographical awareness, and rapid automatized naming at Time 1 as control variables. Latent growth modeling was conducted to analyze the data. Univariate models separately calculated children's initial levels and growth rates in compounding awareness and vocabulary knowledge. Bivariate model was used to examine the direction of the developmental relationships between the two variables with other cognitive and linguistic variables and the autoregression controlled. The results demonstrated that the initial level of compounding awareness predicted the growth rate of vocabulary knowledge, and the reverse relation was also found, after controlling for other cognitive and linguistic variables and the autoregression. The results suggested a reciprocal developmental relationship between children's compounding awareness and vocabulary knowledge for Chinese children, a finding that informs current models of the relationship between morphological awareness and vocabulary knowledge.

  1. Controlled Vocabularies and Ontologies for Oceanographic Data: The R2R Eventlogger Project

    NASA Astrophysics Data System (ADS)

    Coburn, E.; Maffei, A. R.; Chandler, C. L.; Raymond, L. M.

    2012-12-01

    Research vessels coordinated by the United States University-National Oceanographic Laboratory System (US-UNOLS) collect data which is considered an important oceanographic resource. The NSF-funded Rolling Deck to Repository (R2R) project aims to improve access to this data and diminish the barriers to use. One aspect of the R2R project has been to develop a shipboard scientific event logging system, Eventlogger, that incorporates best practice guidelines, controlled vocabularies, a cruise metadata schema, and a scientific event log. This will facilitate the eventual ingestion of datasets into oceanographic data repositories for subsequent integration and synthesis by investigators. One important aspect of this system is the careful use of controlled vocabularies and ontologies. Existing ontologies, where available, will be used and others will be developed. The use of internationally-informed, consensus-driven controlled vocabularies will make datasets more interoperable, and discoverable. The R2R Eventlogger project is led by Woods Hole Oceanographic Institution (WHOI), and the management of the controlled vocabularies and mapping of these vocabularies to authoritative community vocabularies are led by the Data Librarian in the Marine Biological Laboratory/Woods Hole Oceanographic Institution (MBLWHOI) Library. The first target vocabulary is oceanographic instruments. Management of this vocabulary has thus far consisted of reconciling local community terms with the more widely used SeaDataNet Device Vocabulary terms. Rather than adopt existing terms, often the local terms are mapped by data managers in the NSF-funded Biological and Chemical Oceanographic Data Management Office (BCO-DMO) to the existing terms as they are given by investigators and often provide important information and meaning. New terms (often custom, or modified instruments) are submitted for review to the SeaDataNet community listserv for discussion and eventual incorporation into the Device

  13. The effects of problem content and scientific background on information search and the assessment and valuation of correlations.

    PubMed

    Soffer, Shira; Kareev, Yaakov

    2011-01-01

    The effects of problem contents and one's scientific background on the detection of correlations and the assessment of their strength were studied using a task that required active data search, assessment of the strength of a correlation, and monetary valuation of the correlation's predictive utility. Participants (N = 72) who were trained either in the natural sciences or in the social sciences and humanities explored data sets differing in contents and actual strength of correlation. Data search was consistent across all variables: Participants drew relatively small samples whose relative sizes would favor the detection of a correlation, if one existed. In contrast, the assessment of the correlation strength and the valuation of its predictive utility were strongly related not only to its objective strength, but also to the correspondence between problem contents and one's scientific background: When the two matched, correlations were judged to be stronger and more valuable than when they did not.

    Mobile robots are of great help for automatic monitoring tasks in different environments. One of the first tasks that needs to be addressed when creating these kinds of robotic systems is modeling the robot environment. This work proposes a pipeline to build an enhanced visual model of a robot environment indoors. Vision based recognition approaches frequently use quantized feature spaces, commonly known as Bag of Words (BoW) or vocabulary representations. A drawback using standard BoW approaches is that semantic information is not considered as a criteria to create the visual words. To solve this challenging task, this paper studies how to leverage the standard vocabulary construction process to obtain a more meaningful visual vocabulary of the robot work environment using image sequences. We take advantage of spatio-temporal constraints and prior knowledge about the position of the camera. The key contribution of our work is the definition of a new pipeline to create a model of the environment. This pipeline incorporates (1) tracking information to the process of vocabulary construction and (2) geometric cues to the appearance descriptors. Motivated by long term robotic applications, such as the aforementioned monitoring tasks, we focus on a configuration where the robot camera points to the ceiling, which captures more stable regions of the environment. The experimental validation shows how our vocabulary models the environment in more detail than standard vocabulary approaches, without loss of recognition performance. We show different robotic tasks that could benefit of the use of our visual vocabulary approach, such as place recognition or object discovery. For this validation, we use our publicly available data-set. PMID:27070607

    2009-03-01

    In social cognition, knowledge-based validation of information is usually regarded as relying on strategic and resource-demanding processes. Research on language comprehension, in contrast, suggests that validation processes are involved in the construction of a referential representation of the communicated information. This view implies that individuals can use their knowledge to validate incoming information in a routine and efficient manner. Consistent with this idea, Experiments 1 and 2 demonstrated that individuals are able to reject false assertions efficiently when they have validity-relevant beliefs. Validation processes were carried out routinely even when individuals were put under additional cognitive load during comprehension. Experiment 3 demonstrated that the rejection of false information occurs automatically and interferes with affirmative responses in a nonsemantic task (epistemic Stroop effect). Experiment 4 also revealed complementary interference effects of true information with negative responses in a nonsemantic task. These results suggest the existence of fast and efficient validation processes that protect mental representations from being contaminated by false and inaccurate information.

    Data integration act as the preliminary entry point as we enter the era of big data in many scientific domains. However the reusefulness of various dataset has met the hurdle due to different initial of interests of different parties, therefore different vocabularies in describing similar or semantically related concepts. In this scenario it is vital to devise an automatic or semi-supervised algorithm to facilitate the convergence of different vocabularies. The Ocean Data Interoperability Platform (ODIP) seeks to increase data sharing across scientific domains and international boundaries by providing a forum to harmonize diverse regional data systems. ODIP participants from the US include the Rolling Deck to Repository (R2R) program, whose mission is to capture, catalog, and describe the underway/environmental sensor data from US oceanographic research vessels and submit the data to public long-term archives. In an attempt to harmonize these regional data systems, especially vocabularies, R2R recognizes the value of the SeaDataNet vocabularies served by the NERC Vocabulary Server (NVS) hosted at the British Oceanographic Data Centre as a trusted, authoritative source for describing many oceanographic research concepts such as instrumentation. In this work, we make use of the semantic relations in the vocabularies served by NVS to build a Bayesian network and take advantage of the idea of entropy in evaluating the correlation between different concepts and keywords. The performance of the model is evaluated against matching instruments from R2R against the SeaDataNet instrument vocabularies based on calculated confidence scores in the instrument pairings. These pairings with their scores can then be analyzed for assertion growing the interoperability of the R2R vocabulary through its links to the SeaDataNet entities.

    resources that link daily SAMOS data to descriptors such as parameters, time and location information, quality assurance reports, and cruise tracks will also be described. The data is housed on a Thematic Real-time Environmental Distributed Data Services (THREDDS) data server, so these RDF resources will enable enhanced retrieval by any of the linked descriptors. We will showcase our collaboration with the Rolling Deck to Repository (R2R) program to develop SPARQL endpoints that distribute SAMOS content. R2R packages and transmits data on a per cruise basis, so an immediate result of the SAMOS exposure will be the narrowing of the gap between expedition type data (e.g. R2R cruises) and SAMOS observatory type data. The authors will present the development of RDF resources that will collectively expose shipboard data, vocabularies, and quality assurance reports in an overall structure which will serve as the basis for a COAPS SPARQL endpoint, enabling easier programmatic access to SAMOS data.

    Measurements of exposure rates using thermoluminescent dosimeters placed within residences in the Oak Ridge/Knoxville area are presented. The objective of this investigation was to determine the radiation component acquired by Oak Ridge National Laboratory employee personnel dosimeter-security badges during residential badge storage and to develop a model to predict the radiation exposure rate in Oak Ridge/Knoxville-area homes. The exposure rates varied according to building material used and geographic location. Exposure rates were higher in the fall and lower in the spring; stone residences had a higher average dose equivalent rate than residences made of wood. An average yearly exposure rate was determined to be 78 millirems per year for the Oak Ridge-area homes. This value can be compared to the natural background radiation dose equivalent rate in the United States of 80 to 200 millirems per year.

    The application of veterinary medical products to livestock can impact soil organisms in manure-amended fields or adversely affect organisms that colonize dung pats of treated animals and potentially retard the degradation of dung on pastures. For this reason, the authorization process for veterinary medicinal products in the European Union includes a requirement for higher-tier tests when adverse effects on dung organisms are observed in single-species toxicity tests. However, no guidance documents for the performance of higher-tier tests are available. Hence, an international research project was undertaken to develop and validate a proposed test method under varying field conditions of climate, soil, and endemic coprophilous fauna at Lethbridge (Canada), Montpellier (France), Zurich (Switzerland), and Wageningen (The Netherlands). The specific objectives were to determine if fecal residues of an anthelmintic with known insecticidal activity (ivermectin) showed similar effects across sites on 1) insects breeding in dung of treated animals, 2) coprophilous organisms in the soil beneath the dung, and 3) rates of dung degradation. By evaluating the effects of parasiticides on communities of dung-breeding insects and soil fauna under field conditions, the test method meets the requirements of a higher-tier test as mandated by the European Union. The present study provides contextual information on authorization requirements for veterinary medicinal products and on the structure and function of dung and soil organism communities. It also provides a summary of the main findings. Subsequent studies on this issue provide detailed information on different aspects of this overall project.

  2. A case study of a vocabulary strategy in a high school class of special education students

    NASA Astrophysics Data System (ADS)

    Prevost, Jill K.

    In the United States, almost 7000 students drop out of high school every day and the most common reason is academic failure. The economic, social, and emotional cost of dropping out of high school are enormous. Vocabulary knowledge is essential for students to grasp the concepts of a content area and there has been little research reported for scaffolding vocabulary learning in content classes. The purpose of this study was to investigate a vocabulary instructional strategy in a high school biology class. The research questions focused on understanding the vocabulary instructional strategy and student perception of the strategy. This was an evaluative case study using a convenience sample of a college preparatory biology class of special education students. Participants included eight males and two females who were identified as having learning, emotional or health disabilities with average to low average intelligence. Informal interviews, observations, school records, student and teacher artifacts and rich description were used for data triangulation. Analysis involved coding and grouping data by category, and identification of relationships between categories. Three themes emerged from this study: Students believed the strategy helped them to learn vocabulary, the strategy gave direction to instruction, and the strategy can be difficult to implement. The skill level of our future work force and the health of our society is linked to our nation's high school graduation rate. Development of instructional strategies that result in student academic success will improve our high school graduation rate which will result in positive social change.

  3. Elementary Preservice Teachers' Science Vocabulary: Knowledge and Application

    2013-03-01

    Science vocabulary knowledge plays a role in understanding science concepts, and science knowledge is measured in part by correct use of science vocabulary (Lee et al. in J Res Sci Teach 32(8):797-816, 1995). Elementary school students have growing vocabularies and many are learning English as a secondary language or depend on schools to learn academic English. Teachers must have a clear understanding of science vocabulary in order to communicate and evaluate these understandings with students. The present study measured preservice teachers' vocabulary knowledge during a science methods course and documented their use of science vocabulary during peer teaching. The data indicate that the course positively impacted the preservice teachers' knowledge of select elementary science vocabulary; however, use of science terms was inconsistent in microteaching lessons. Recommendations include providing multiple vocabulary instruction strategies in teacher preparation.

    Purpose of this study is to explore the status of R and D in Japan and the ability of US researchers to keep abreast of Japanese technical advances. US researchers familiar with R and D activities in Japan were interviewed in ten fields that are relevant to the more efficient use of energy: amorphous metals, biotechnology, ceramics, combustion, electrochemical energy storage, heat engines, heat transfer, high-temperature sensors, thermal and chemical energy storage, and tribology. The researchers were questioned about their perceptions of the strengths of R and D in Japan, comparative aspects of US work, and the quality of available information sources describing R and D in Japan. Of the ten related fields, the researchers expressed a strong perception that significant R and D is under way in amorphous metals, biotechnology, and ceramics, and that the US competitive position in these technologies will be significantly challenged. Researchers also identified alternative emphases in Japanese R and D programs in these areas that provide Japan with stronger technical capabilities. For example, in biotechnology, researchers noted the significant Japanese emphasis on industrial-scale bioprocess engineering, which contrasts with a more meager effort in the US. In tribology, researchers also noted the strength of the chemical tribology research in Japan and commented on the effective mix of chemical and mechanical tribology research. This approach contrasts with the emphasis on mechanical tribology in the US.

    A critical component of the Neuroscience Information Framework (NIF) project is a consistent, flexible terminology for describing and retrieving neuroscience-relevant resources. Although the original NIF specification called for a loosely structured controlled vocabulary for describing neuroscience resources, as the NIF system evolved, the requirement for a formally structured ontology for neuroscience with sufficient granularity to describe and access a diverse collection of information became obvious. This requirement led to the NIF standardized (NIFSTD) ontology, a comprehensive collection of common neuroscience domain terminologies woven into an ontologically consistent, unified representation of the biomedical domains typically used to describe neuroscience data (e.g., anatomy, cell types, techniques), as well as digital resources (tools, databases) being created throughout the neuroscience community. NIFSTD builds upon a structure established by the BIRNLex, a lexicon of concepts covering clinical neuroimaging research developed by the Biomedical Informatics Research Network (BIRN) project. Each distinct domain module is represented using the Web Ontology Language (OWL). As much as has been practical, NIFSTD reuses existing community ontologies that cover the required biomedical domains, building the more specific concepts required to annotate NIF resources. By following this principle, an extensive vocabulary was assembled in a relatively short period of time for NIF information annotation, organization, and retrieval, in a form that promotes easy extension and modification. We report here on the structure of the NIFSTD, and its predecessor BIRNLex, the principles followed in its construction and provide examples of its use within NIF. PMID:18975148

    This study examined the effects of the verbal labels procedure and vocabulary skills on low-socioeconomic status (SES) preschool children's eyewitness memory. Children (N = 176) aged 3-5 years witnessed a conflict event and were then questioned about it in either a standard or a verbal labels interview. Findings revealed that children with higher rather than lower vocabulary skills produced more complete and accurate memories. Children who were given the verbal labels interview recalled more information, which included both correct and incorrect details. Overall, the verbal labels procedure did not improve children's performance on direct questions, but children with low vocabulary skills answered direct questions more accurately if they were given the verbal labels interview than when they were not. Implications of the findings for memory performance of low-SES children are discussed.

    The Plant Ontology Consortium (POC) (www.plantontology.org) is a collaborative effort among several plant databases and experts in plant systematics, botany and genomics. A primary goal of the POC is to develop simple yet robust and extensible controlled vocabularies that accurately reflect the biology of plant structures and developmental stages. These provide a network of vocabularies linked by relationships (ontology) to facilitate queries that cut across datasets within a database or between multiple databases. The current version of the ontology integrates diverse vocabularies used to describe Arabidopsis, maize and rice (Oryza sp.) anatomy, morphology and growth stages. Using the ontology browser, over 3500 gene annotations from three species-specific databases, The Arabidopsis Information Resource (TAIR) for Arabidopsis, Gramene for rice and MaizeGDB for maize, can now be queried and retrieved.

    Semantic descriptions of observed properties and associated units of measure are fundamental to understanding of environmental observations, including groundwater, surface water and marine water quality. Semantic descriptions can be captured in machine-readable ontologies and vocabularies, thus providing support for the annotation of observation values from the disparate data sources with appropriate and accurate metadata, which is critical for achieving semantic interoperability. However, current stand-alone water quality vocabularies provide limited support for cross-system comparisons or data fusion. To enhance semantic interoperability, the alignment of water-quality properties with definitions of chemical entities and units of measure in existing widely-used vocabularies is required. Modern ontologies and vocabularies are expressed, organized and deployed using Semantic Web technologies. We developed an ontology for observed properties (i.e. a model for expressing appropriate controlled vocabularies) which extends the NASA/TopQuadrant QUDT ontology for Unit and QuantityKind with two additional classes and two properties (see accompanying paper by Cox, Simons and Yu). We use our ontology to populate the Water Quality vocabulary with a set of individuals of each of the four key classes (and their subclasses), and add appropriate relationships between these individuals. This ontology is aligned with other relevant stand-alone Water Quality vocabularies and domain ontologies. Developing the Water Quality vocabulary involved two main steps. First, the Water Quality vocabulary was populated with individuals of the ObservedProperty class, which was determined from a census of existing datasets and services. Each ObservedProperty individual relates to other individuals of Unit and QuantityKind (taken from QUDT where possible), and to IdentifiedObject individuals. As a large fraction of observed water quality data are classified by the chemical substance involved, the

    This article discusses the importance of using decontextualized language, or language that is removed from the here and now including pretend, narrative, and explanatory talk, with preschool children. The literature on parents' use of decontextualized language is reviewed and results of a longitudinal study of parent decontextualized language input in relation to child vocabulary development are explained. The main findings are that parents who provide their preschool children with more explanations and narrative utterances about past or future events in the input have children with larger vocabularies 1 year later, even with quantity of parent input and child prior vocabulary skill controlled. Recommendations for how to engage children in decontextualized language conversations are provided.

    2015-01-01

    Online health communities provide popular platforms for individuals to exchange psychosocial support and form ties. Although regular active participation (i.e., posting to interact with other members) in online health communities can provide important benefits, sustained active participation remains challenging for these communities. Leveraging previous literature on homophily (i.e., “love of those who are like themselves”), we examined the relationship between vocabulary similarity (i.e., homophily of word usage) of thread posts and members’ future interaction in online health communities. We quantitatively measured vocabulary similarity by calculating, in a vector space model, cosine similarity between the original post and the first reply in 20,499 threads. Our findings across five online health communities suggest that vocabulary similarity is a significant predictor of members’ future interaction in online health communities. These findings carry practical implications for facilitating and sustaining online community participation through beneficial effects of homophily in the vocabulary of essential peer support.

    2015-01-01

    We report results from two studies on the underlying dimensions of morphological awareness and vocabulary knowledge in elementary-aged children. In Study 1, 99 fourth-grade students were given multiple measures of morphological awareness and vocabulary. A single factor accounted for individual differences in all morphology and vocabulary assessments. Study 2 extended these results by giving 90 eighth-grade students expanded measures of vocabulary and morphology that assessed (a) definitional knowledge, (b) usage, (c) relational knowledge, and (d) knowledge of morphological variants, with each potential aspect of knowledge assessed using an identical set of 23 words to control for differential knowledge of specific vocabulary items. Results indicated that a single-factor model that encompassed morphological and vocabulary knowledge provided the best fit to the data. Finally, explanatory item response modeling was used to investigate sources of variance in the vocabulary and morphological awareness tasks we administered. Implications for assessment and instruction are discussed. PMID:26273128

  17. Development of a change model for a controlled medical vocabulary.

    Oliver, D. E.; Shahar, Y.

    1997-01-01

    Managing change in controlled medical vocabularies is labor intensive and costly, but change is inevitable if vocabularies are to be kept up to date. The changes that are appropriate for a controlled medical vocabulary depend on the data stored for that vocabulary, and those data in turn depend on the needs of users. The set of change operations is the change model; the data stored about concepts comprise the concept model. Because the change model depends directly on the concept model, a discussion of the former necessitates a discussion of the latter. In this paper, we first present a set of tasks that we believe controlled medical vocabularies should handle. Next, we describe our concept model for a controlled medical vocabulary. Then, we review the literature on changes in existing vocabulary systems. Finally, we present our change model. We call our system, which incorporates the concept model and change model, the General Online Dictionary of Medicine (GOLDMINE). PMID:9357697

    This paper describes an original approach to generating scenarios for the purpose of testing the algorithms used to detect special nuclear materials (SNM) that incorporates the use of ontologies. Separating the signal of SNM from the background requires sophisticated algorithms. To assist in developing such algorithms, there is a need for scenarios that capture a very wide range of variables affecting the detection process, depending on the type of detector being used. To provide such a cpability, we developed an ontology-driven information system (ODIS) for generating scenarios that can be used in creating scenarios for testing of algorithms for SNMmore » detection. The ontology-driven scenario generator (ODSG) is an ODIS based on information supplied by subject matter experts and other documentation. The details of the creation of the ontology, the development of the ontology-driven information system, and the design of the web user interface (UI) are presented along with specific examples of scenarios generated using the ODSG. We demonstrate that the paradigm behind the ODSG is capable of addressing the problem of semantic complexity at both the user and developer levels. Compared to traditional approaches, an ODIS provides benefits such as faithful representation of the users' domain conceptualization, simplified management of very large and semantically diverse datasets, and the ability to handle frequent changes to the application and the UI. Furthermore, the approach makes possible the generation of a much larger number of specific scenarios based on limited user-supplied information« less

  1. Incidental acquisition of foreign language vocabulary through brief multi-modal exposure.

    Bisson, Marie-Josée; van Heuven, Walter J B; Conklin, Kathy; Tunney, Richard J

    2013-01-01

    First language acquisition requires relatively little effort compared to foreign language acquisition and happens more naturally through informal learning. Informal exposure can also benefit foreign language learning, although evidence for this has been limited to speech perception and production. An important question is whether informal exposure to spoken foreign language also leads to vocabulary learning through the creation of form-meaning links. Here we tested the impact of exposure to foreign language words presented with pictures in an incidental learning phase on subsequent explicit foreign language learning. In the explicit learning phase, we asked adults to learn translation equivalents of foreign language words, some of which had appeared in the incidental learning phase. Results revealed rapid learning of the foreign language words in the incidental learning phase showing that informal exposure to multi-modal foreign language leads to foreign language vocabulary acquisition. The creation of form-meaning links during the incidental learning phase is discussed.

  3. Possibilities and Implications of Using the ICF and Other Vocabulary Standards in Electronic Health Records.

    PubMed

    Vreeman, Daniel J; Richoz, Christophe

    2015-12-01

    There is now widespread recognition of the powerful potential of electronic health record (EHR) systems to improve the health-care delivery system. The benefits of EHRs grow even larger when the health data within their purview are seamlessly shared, aggregated and processed across different providers, settings and institutions. Yet, the plethora of idiosyncratic conventions for identifying the same clinical content in different information systems is a fundamental barrier to fully leveraging the potential of EHRs. Only by adopting vocabulary standards that provide the lingua franca across these local dialects can computers efficiently move, aggregate and use health data for decision support, outcomes management, quality reporting, research and many other purposes. In this regard, the International Classification of Functioning, Disability, and Health (ICF) is an important standard for physiotherapists because it provides a framework and standard language for describing health and health-related states. However, physiotherapists and other health-care professionals capture a wide range of data such as patient histories, clinical findings, tests and measurements, procedures, and so on, for which other vocabulary standards such as Logical Observation Identifiers Names and Codes and Systematized Nomenclature Of Medicine Clinical Terms are crucial for interoperable communication between different electronic systems. In this paper, we describe how the ICF and other internationally accepted vocabulary standards could advance physiotherapy practise and research by enabling data sharing and reuse by EHRs. We highlight how these different vocabulary standards fit together within a comprehensive record system, and how EHRs can make use of them, with a particular focus on enhancing decision-making. By incorporating the ICF and other internationally accepted vocabulary standards into our clinical information systems, physiotherapists will be able to leverage the potent

  4. Use of standard vocabulary services in validation of water resources data

    2010-05-01

    Ontology repositories are increasingly being exposed through vocabulary and concept services. Primarily this is in support of resource discovery. Thesaurus functionality and even more sophisticated reasoning offers the possibility of overcoming the limitations of simple text-matching and tagging which is the basis of most search. However, controlled vocabularies have other important roles in distributed systems: in particular in constraining content validity. A national water information system established by the Australian Bureau of Meterorology ('the Bureau') has deployed a system for ingestion of data from multiple providers. This uses a http interface onto separately maintained vocabulary services as part of the quality assurance chain. With over 200 data providers potentially transferring data to the Bureau, a standard XML-based Water Data Transfer Format (WDTF) was developed for receipt of data into an integrated national water information system. The WDTF schema was built upon standards from the Open Geospatial Consortium (OGC). The structure and syntax specified by a W3C XML Schema is complemented by additional constraints described using Schematron. These implement important content requirements and business rules including: • Restricted cardinality: where optional elements and attributes inherited from the base standards become mandatory in the application, or repeatable elements or attributes are limited to one or omitted. For example, the sampledFeature element from O&M is optional but is mandatory for a samplingPoint element in WDTF. • Vocabulary checking: WDTF data use seventeen vocabularies or code lists derived from Regulations under the Commonwealth Water Act 2007. Examples of codelists are the Australian Water Regulations list, observed property vocabulary, and units of measures. • Contextual constraints: in many places, the permissible value is dependent on the value of another field. For example, within observations the unit of measure

    An attractive property of ensemble data assimilation methods is that they provide flow dependent background error covariance estimates which can be used to update fields of observed variables as well as fields of unobserved model variables. Two methods to estimate background error covariances are introduced which share the above property with ensemble data assimilation methods but do not involve the integration of multiple model trajectories. Instead, all the necessary covariance information is obtained from a single model integration. The Space Adaptive Forecast error Estimation (SAFE) algorithm estimates error covariances from the spatial distribution of model variables within a single state vector. The Flow Adaptive error Statistics from a Time series (FAST) method constructs an ensemble sampled from a moving window along a model trajectory. SAFE and FAST are applied to the assimilation of Argo temperature profiles into version 4.1 of the Modular Ocean Model (MOM4.1) coupled to the GEOS-5 atmospheric model and to the CICE sea ice model. The results are validated against unassimilated Argo salinity data. They show that SAFE and FAST are competitive with the ensemble optimal interpolation (EnOI) used by the Global Modeling and Assimilation Office (GMAO) to produce its ocean analysis. Because of their reduced cost, SAFE and FAST hold promise for high-resolution data assimilation applications.

  11. Theoretical and methodological implications of language experience and vocabulary skill: priming of strongly and weakly associated words.

    PubMed

    Devitto, Zana; Burgess, Curt

    2004-07-01

    The effect of second language experience and vocabulary ability was investigated in a semantic priming experiment with weakly related English word pairs (e.g., city-grass). Participants made lexical decisions to targets preceded by unrelated or weakly related primes or to nonword targets preceded by words. Reliable priming was found for monolingual participants; participants who had acquired a second language showed either marginal or nonreliable effects. A similar pattern of results was found with the analysis of vocabulary ability. Only participants with the greater vocabulary ability showed a priming effect. Although previous research has shown that participants with a broad range of linguistic backgrounds demonstrate the typical semantic priming effect (e.g., green-grass) with strongly associated word pairs, weaker relationships seem to require an extensive contextual history for retrieval.

    Mastery of language skills is an important predictor of daily functioning and health. Vocabulary comprehension and reading decoding are relatively quick and easy to measure and correlate highly with overall cognitive functioning, as well as with success in school and work. New measures of vocabulary comprehension and reading decoding (in both English and Spanish) were developed for the NIH Toolbox Cognition Battery (CB). In the Toolbox Picture Vocabulary Test (TPVT), participants hear a spoken word while viewing four pictures, and then must choose the picture that best represents the word. This approach tests receptive vocabulary knowledge without the need to read or write, removing the literacy load for children who are developing literacy and for adults who struggle with reading and writing. In the Toolbox Oral Reading Recognition Test (TORRT), participants see a letter or word onscreen and must pronounce or identify it. The examiner determines whether it was pronounced correctly by comparing the response to the pronunciation guide on a separate computer screen. In this chapter, we discuss the importance of language during childhood and the relation of language and brain function. We also review the development of the TPVT and TORRT, including information about the item calibration process and results from a validation study. Finally, the strengths and weaknesses of the measures are discussed. PMID:23952202

    2010-11-13

    Use of terminology standards facilitates aggregating data from multiple sources for information retrieval, exchange and analysis. However, medical vocabularies are continuously updated and incorporating those changes consistently into clinical data warehouses requires rigorous methodology. To integrate pharmacy data from two hospital pharmacy information systems the Stanford Translational Research Integrated Database Environment (STRIDE) project mapped medication orders to RxNorm content using the RxNorm drug model. In order to keep the data relevant and up-to-date, we developed a strategy for updating to RxNorm, while preserving the original meaning and mapping of the legacy data. This case study discusses managing the vocabulary update by following the RxNorm content maintenance strategy and supplementing it with operations to retain access to its drug model information.

    In view of an ever-increasing infiltration of the German medical vocabulary by Britishisms and Americanisms, a linguistic attempt was made to categorize this phraseology as follows: more or less incorporated terminology, "internationalized" terms, identical translations, unnecessary use of English expressions instead of German synonyms, borrowing from the English with an alteration of the original meaning, and German neologisms on the basis of English vocabular material. Specimens from all these categories are enumerated.

    PubMed

    Bodenreider, O; Nelson, S J; Hole, W T; Chang, H F

    1998-01-01

    The Unified Medical Language System (UMLS) contains semantic information about terms from various sources, each concept can be understood and located by its relationships to other concepts: this is a result of the organizing principle of semantic locality. We describe a method in which the semantic relationships between concepts are used to map concepts from different vocabularies in the UMLS. Applied to mapping concepts to MeSH, this method is able to map 50 to 65% of the non-MeSH concepts to MeSH. A manual review of the mapping shows a relevance rate of 61%. Causes of failure include a lack of consistently represented relationships in the UMLS, and some inconsistencies in the categorization of the concepts. The limits of this method are discussed, as well as possible adaptations for other uses.

    Appendices A to C to the 'Municipal Waste Combustion: Background Information for Promulgated Standards and Guidelines - Summary of Public Comments and Responses' (PB91-168534), address key technical issues related to the promulgated rules for municipal waste combustors (MWC's). Appendix A provides analysis of the continuous SO2 control capabilities of spray dryer/fabric filter (SD/FF) and spray dryer/electrostatic precipitator (SD/ESP) control systems for MWC's. Achievable SO2 performance levels for these systems are determined based on the analysis. Similarly, Appendix B provides analysis of continuous NOX emissions data from MWC's. Results are presented for the statistical analysis of NOX data obtained from a grate-fired mass burn waterwall MWC using selective noncatalytic reduction (SNCR) to reduce NOX emissions and from a rotary mass burn waterwall MWC designed to limit NOX emissions through combustion control. Appendix C provides additional MWC emissions test data which became available following proposal of the standards and guidelines for MWC's on December 20, 1989. The appendix reviews data at four MWC's with either unique air pollution control technologies or emissions which are higher than for similarly controlled MWC's that had been previously examined.

    This study examines how STEM (science, technology, engineering, and mathematics) inquiry-based learning through a hands-on engineering design can be beneficial in helping students acquire academic vocabulary. This research took place in a second grade dual- language classroom in a public, suburban elementary school. English language learners, students who speak Spanish at home, and native English speakers were evaluated in this study. Each day, students were presented with a general academic vocabulary focus word during an engineering design challenge. Vocabulary pre-tests and post-tests as well as observation field notes were used to evaluate the student's growth in reading and defining the focus academic vocabulary words. A quiz and KSB (knowledge and skill builder) packet were used to evaluate students' knowledge of science and math content and engineering design. The results of this study indicate that engineering design is an effective means for teaching academic vocabulary to students with varying levels of English proficiency.

  1. Emotional expression and vocabulary learning in adults and children.

    PubMed

    Clément, Fabrice; Bernard, Stéphane; Grandjean, Didier; Sander, David

    2013-01-01

    A great deal of what we know about the world has not been learned via first-hand observation but thanks to others' testimony. A crucial issue is to know which kind of cues people use to evaluate information provided by others. In this context, recent studies in adults and children underline that informants' facial expressions could play an essential role. To test the importance of the other's emotions in vocabulary learning, we used two avatars expressing happiness, anger or neutral emotions when proposing different verbal labels for an unknown object. Experiment 1 revealed that adult participants were significantly more likely than chance to choose the label suggested by the avatar displaying a happy face over the label suggested by the avatar displaying an angry face. Experiment 2 extended these results by showing that both adults and children as young as 3 years old showed this effect. These data suggest that decision making concerning newly acquired information depends on informant's expressions of emotions, a finding that is consistent with the idea that behavioural intents have facial signatures that can be used to detect another's intention to cooperate.

  2. The Alaska Mineral Resource Assessment Program; background information to accompany geologic and mineral-resource maps of the Cordova and Middleton Island quadrangles, southern Alaska

    USGS Publications Warehouse

    Winkler, Gary R.; Plafker, George; Goldfarb, R.J.; Case, J.E.

    1992-01-01

    report summarizes recent results of integrated geological, geochemical, and geophysical field and laboratory studies conducted by the U.S. Geological Survey in the Cordova and Middleton Island 1?x3 ? quadrangles of coastal southern Alaska. Published open-file reports and maps accompanied by descriptive and interpretative texts, tables, diagrams, and pertinent references provide background information for a mineral-resource assessment of the two quadrangles. Mines in the Cordova and Middleton Island quadrangles produced copper and byproduct gold and silver in the first three decades of the 20th century. The quadrangles may contain potentially significant undiscovered resources of precious and base metals (gold, silver, copper, zinc, and lead) in veins and massive sulfide deposits hosted by Cretaceous and Paleogene sedimentary and volcanic rocks. Resources of manganese also may be present in the Paleogene rocks; uranium resources may be present in Eocene granitic rocks; and placer gold may be present in beach sands near the mouth of the Copper River, in alluvial sands within the canyons of the Copper River, and in smaller alluvial deposits underlain by rocks of the Valdez Group. Significant coal resources are present in the Bering River area, but difficult access and structural complexities have discouraged development. Investigation of numerous oil and gas seeps near Katalla in the eastern part of the area led to the discovery of a small, shallow field from which oil was produced between 1902 and 1933. The field has been inactive since, and subsequent exploration and drilling onshore near Katalla in the 1960's and offshore near Middleton Island on the outer continental shelf in the 1970's and 1980's was not successful.

  13. Word learning in children with vocabulary deficits.

    PubMed

    Nash, Marysia; Donaldson, Morag L

    2005-04-01

    Word learning in 16 children with specific language impairment (SLI) was compared with that of chronological-age controls (CAC) and vocabulary-age controls (VAC), to examine the extent and nature of word-learning deficits in the children with SLI. The children were exposed to novel words in a story and an explicit teaching context. Five tasks assessed how much the children had learned about the words' phonological form and semantic properties after 6 repetitions (Time 1) and again after 12 repetitions (Time 2) of the words in each context. The SLI group performed significantly worse than the CAC group at both Time 1 and Time 2 on all measures of the words presented in both contexts. They performed similarly to the VAC group (who were on average 21/2 years younger) on Time 1 and Time 2 measures from both contexts, except for the Naming task at Time 2, on which their performance was significantly lower. These findings suggest that children with vocabulary deficits have difficulties with both phonological and semantic aspects of word learning.

    Users of drug information typically focus their attention at different levels of description in different situations, such as medication ordering or dispensing. Computer systems utilizing drug information to support such activities must accommodate these multiple perspectives. This paper presents an approach to conceptualizing drug descriptions at multiple levels and outlines key features of an underlying information model that can serve as the basis for a concept-oriented medication vocabulary. These features include dose forms, routes of administration, as well as links to multiple drug classification schemes and medical problems. Implementation, standards, and maintenance issues related to the model are also discussed. PMID:9929342
