Fachkatalog Neuguinea / Stadt- und Universitätsbibliothek Frankfurt am Main
No full textAus Anlaß des Kongresses der "Deutsch-Pazifischen Gesellschaft" im Juni 1981 in Düsseldorf legt die Stadt- und Universitätsbibliothek Frankfuxt am Main ein Verzeichnis ihrer Bestände zum Raum "Neuguinea" vor . Dabei umfaßt der Katalog sowohl die Literatur zu "Papua-Neuguinea" (Niugini)" als auch zur indonesischen Provinz "West-Irian (Irian Jaya)". Aus Gründen des geographischen Zusammenhangs werden in einem Anhang allgemeine Publikationen zum Raum Melanesien in den Katalog aufgenommen. Die gezielte Sammlung der Literatur zu diesem Raum ist ein Ergebnis der Zuweisung des Sondersarnmelgebietes "Ozeanian" durch die Deutsche Forschungagemeinschaft an die Frankfurter Stadt- und Univeraitätsbibliothek. Dabei liegt der Schwerpunkt auf der Sammlung historischer und ethnologischer Literatur. Grundlage des Katalogausdruckes ist der Länderteil des Sachkataloges der Bibliothek, der nach feststehenden Länderkennziffern, Fachgruppen und Schlüsselnummern gegliedert ist. Unter jeder Schlüsselnummer sind die Eintragungen chronologisch geordnet. Auf jeder Titelkarte befindet sich rechts oben die Signatur, unter der das Buch über Fernleihe bei der Stadt- und Universitätsbibliothek Frankfurt am Main bestellt werden kann

MeSH term explosion and author rank improve expert recommendations
No full textInformation overload is an often-cited phenomenon that reduces the productivity, efficiency and efficacy of scientists. One challenge for scientists is to find appropriate collaborators in their research. The literature describes various solutions to the problem of expertise location, but most current approaches do not appear to be very suitable for expert recommendations in biomedical research. In this study, we present the development and initial evaluation of a vector space model-based algorithm to calculate researcher similarity using four inputs: 1) MeSH terms of publications; 2) MeSH terms and author rank; 3) exploded MeSH terms; and 4) exploded MeSH terms and author rank. We developed and evaluated the algorithm using a data set of 17,525 authors and their 22,542 papers. On average, our algorithms correctly predicted 2.5 of the top 5/10 coauthors of individual scientists. Exploded MeSH and author rank outperformed all other algorithms in accuracy, followed closely by MeSH and author rank. Our results show that the accuracy of MeSH term-based matching can be enhanced with other metadata such as author rank

Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

No full text"Closing the R&D Gap, Evaluating the Sources of R&D Spending"
No full textBoth spending and tax policies have been implemented in the United States with the goal of stimulating private sector research and development (R&D). Karier questions whether current R&D policy, especially the research and experimentation tax credit, can contribute to closing the gap between nondefense expenditures on R&D in the United States and such expenditures in other countries, such as Japan and Germany. He also explores possible changes to our current R&D policy to make it more effective.
Synthesis of flutamide-d(7) and its main metabolite-d(6)
No full textWith the main objective of examining the pharmacokinetics of flutamide, flutamide-d(7) and its main metabolite-d(6) have been prepared. By carboxylation of Grignard-derivative (IV), deuterocarboxylic acid (V) was prepared from which acyl chloride (VI) was obtained by reaction with (COCl)(2). Subsequent reaction of (VI) with 4-nitro-3-trifluoromethylaniline afforded (I). Compound (X) was obtained starting from hydroxyacid (IX), through reaction with TMSCI, (COCl)(2) and subsequent condensation with 4-nitro-3-trifluoromethylaniline. Desilylation of(X) by tetrabutylammonium fluoride, gave (II)
