    Aspects of a systemic philosophy of knowledge: from social facts to data, information and knowledge (2002)
    Bingley : Emerald
    Kybernetes 31 (2002), S. 1099-1120 
    Details
    ISSN: 0368-492X
    Source: Emerald Fulltext Archive Database 1994-2005
    Topics: Computer Science
    Notes: Considers from a cybernetic point of view, a number of philosophical problems raised by the design and utilization of information systems and knowledge management. Discusses the transformation from facts in social systems, via data and information into knowledge, and the practical use of knowledge, which is defined as the cybernetic strategy of action. This paper is normative and conceptual and the research question posed is: How are social facts transformed into data, data into information, and information into knowledge?

    Validation of Bibliometric Indicators in the Field of Microbiology: A Norwegian Case Study (2000)
    Springer
    Scientometrics 49 (2000), S. 7-22

    Notes: Abstract This paper addresses two related issues regarding the validity of bibliometric indicators for the assessment of national performance within a particular scientific field. Firstly, the representativeness of a journal-based subject classification; and secondly, the completeness of the database coverage. Norwegian publishing in microbiology was chosen as a case, using the standard ISI-product National Science Indicators on Diskette (NSIOD) as a source database. By applying an "author-gated" retrieval procedure, we found that only 41 percent of all publications in NSIOD-indexed journals, expert-classified as microbiology, were included under the NSIOD-category Microbiology. Thus, the set of defining core journals only is clearly not sufficient to delineate this complex biomedical field. Furthermore, a subclassification of the articles into different subdisciplines of microbiology revealed systematic differences with respect to representation in NSIOD's Microbiology field; fish microbiology and medical microbiology are particularly underrepresented. In a second step, the individual publication lists from a sample of Norwegian microbiologists were collected and compared with the publications by the same authors, retrieved bibliometrically. The results showed that a large majority (94%) of the international scientific production in Norwegian microbiology was covered by the database NSIOD. Thus, insufficient subfield delineation, and not lack of coverage, appeared to be the main methodological problem in the bibliometric analysis of microbiology.

    Using Linked Micromap Plots to Characterize Omernik Ecoregions (2000)
    Springer
    Data mining and knowledge discovery 4 (2000), S. 43-67 
    Details
    ISSN: 1573-756X
    Keywords: statistical graphics ; LM plots ; multivariate ; spatial data ; Omernik ecoregions ; row plots ; boxplots ; line-height plots
    Source: Springer Online Journal Archives 1860-2000
    Topics: Computer Science
    Notes: Abstract The paper introduces linked micromap (LM) plots for presenting environmental summaries. The LM template includes parallel sequences of micromap, label, and statistical summary graphics panels with attention paid to perceptual grouping, sorting and linking of the summary components. The applications show LM plots for Omernik Level II Ecoregions. The summarized United States continental data includes USGS digital elevation, 30-year normal precipitation and temperature, and 8 million AVHRR pixels classified into 159 types of land cover. One LM plot uses a line-height glyph to represent all 159 land cover percentages per ecoregion. LM plots represent new visualization methodology that is useful in the data and knowledge based pattern representation and knowledge discovery process. The LM plots focus on providing an orienting overview. The overview provides a starting place for subsequent drilling down to what could otherwise be viewed as an overwhelming mass of data. The overview also provides a starting place to learn about the intellectual structure that lies behind the notion of ecoregions and begins to connect this abstract structure to quantitative methods.

    Resistance to an herbivore through engineered cyanogenic glucoside synthesis (2001)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2001-07-28
    Description: The entire pathway for synthesis of the tyrosine-derived cyanogenic glucoside dhurrin has been transferred from Sorghum bicolor to Arabidopsis thaliana. Here, we document that genetically engineered plants are able to synthesize and store large amounts of new natural products. The presence of dhurrin in the transgenic A. thaliana plants confers resistance to the flea beetle Phyllotreta nemorum, which is a natural pest of other members of the crucifer group, demonstrating the potential utility of cyanogenic glucosides in plant defense.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Tattersall, D B -- Bak, S -- Jones, P R -- Olsen, C E -- Nielsen, J K -- Hansen, M L -- Hoj, P B -- Moller, B L -- New York, N.Y. -- Science. 2001 Sep 7;293(5536):1826-8.

    Ascent of dinosaurs linked to an iridium anomaly at the Triassic-Jurassic boundary (2002)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2002-05-23
    Description: Analysis of tetrapod footprints and skeletal material from more than 70 localities in eastern North America shows that large theropod dinosaurs appeared less than 10,000 years after the Triassic-Jurassic boundary and less than 30,000 years after the last Triassic taxa, synchronous with a terrestrial mass extinction. This extraordinary turnover is associated with an iridium anomaly (up to 285 parts per trillion, with an average maximum of 141 parts per trillion) and a fern spore spike, suggesting that a bolide impact was the cause. Eastern North American dinosaurian diversity reached a stable maximum less than 100,000 years after the boundary, marking the establishment of dinosaur-dominated communities that prevailed for the next 135 million years.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Olsen, P E -- Kent, D V -- Sues, H-D -- Koeberl, C -- Huber, H -- Montanari, A -- Rainforth, E C -- Fowell, S J -- Szajna, M J -- Hartline, B W -- New York, N.Y. -- Science. 2002 May 17;296(5571):1305-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Lamont-Doherty Earth Observatory of Columbia University, Palisades, NY 10964, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/12016313" target="_blank"〉PubMed〈/a〉

    Human chromosome 19 and related regions in mouse: conservative and lineage-specific evolution (2001)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2001-07-07
    Description: To illuminate the function and evolutionary history of both genomes, we sequenced mouse DNA related to human chromosome 19. Comparative sequence alignments yielded confirmatory evidence for hypothetical genes and identified exons, regulatory elements, and candidate genes that were missed by other predictive methods. Chromosome-wide comparisons revealed a difference between single-copy HSA19 genes, which are overwhelmingly conserved in mouse, and genes residing in tandem familial clusters, which differ extensively in number, coding capacity, and organization between the two species. Finally, we sequenced breakpoints of all 15 evolutionary rearrangements, providing a view of the forces that drive chromosome evolution in mammals.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Dehal, P -- Predki, P -- Olsen, A S -- Kobayashi, A -- Folta, P -- Lucas, S -- Land, M -- Terry, A -- Ecale Zhou, C L -- Rash, S -- Zhang, Q -- Gordon, L -- Kim, J -- Elkin, C -- Pollard, M J -- Richardson, P -- Rokhsar, D -- Uberbacher, E -- Hawkins, T -- Branscomb, E -- Stubbs, L -- New York, N.Y. -- Science. 2001 Jul 6;293(5527):104-11.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉DOE Joint Genome Institute, Walnut Creek, CA 94598, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11441184" target="_blank"〉PubMed〈/a〉
