Evaluating Citebase, an open access Web-based citation-ranked search and impact discovery service
No full textCitebase is a new citation-ranked search and impact discovery service that measures citations of scholarly research papers which are openly accessible on the Web, i.e. papers that are assessable continuously online. Other services, such as ResearchIndex, have emerged in recent years to offer citation indexing of Web research papers. In the first detailed user evaluation of an open access Web citation indexing service, Citebase has been evaluated by nearly 200 users from different backgrounds. The paper details the procedures used in the evaluation, and analyses the results of this study, which took place between June and October 2002. It was found that within the scope of its primary components, the search interface and services available from its rich bibliographic records, Citebase can be used simply and reliably for the purpose intended, and that it compares favourably with other bibliographic services. It is shown tasks can be accomplished efficiently with Citebase regardless of the background of the user. More data need to be collected and the process refined before it is as reliable for measuring citation impact of indexed papers. Better explanations and guidance are required for first-time users. Coverage is seen as a limiting factor, even though Citebase indexes over 200,000 papers from arXiv. Non-physicists were frustrated at the lack of papers from other sciences. The principle of citation searching of open access archives has thus been demonstrated and need not be restricted to current users. Since the evaluation, Citebase has become a featured service of the ArXiv physics eprint archives

Nielsen acquiring Arbitron: a merger between two monopolies
No full textOn Sep 30, 2013, Nielsen Holdings N.V. announced a deal that it had successfully acquired Arbitron Inc. In this case study, the author discussed some possible impacts the Nielsen and Arbitron merger would have on the participants and the entire media industry. Based on Nielsen and Arbitron’s activities and new cross platform products, Nielsen and Arbitron’s merger would not only affect television and radio measurement, but also the field of cross-platform measurement. The author analyzed this case by providing background information prior to this acquisition, such as the digital viewing trends, online measurement and multi-screen demographics. In order to analyze the results of this case, the author combined Nielsen’s financial performance, new product information, an interview with a Nielsen employee and some comments from Nielsen clients. The results were presented in a “3C” structure; “Company”, “Customer” and “Competition”.M.S., Television Management -- Drexel University, 201
Loxosomella decorata Nielsen, 2017, n. sp.
No full textLoxosomella decorata n. sp. Holotype: Specimen found in the tubes of the maldanid polychaete Axiothella rubrocincta (Johnson, 1901) from an intertidal sandy-muddy bottom, False Bay, San Juan Island, WA, USA, July 2007, collected by Dr Tim Wollesen. SEM preparation deposited in The Natural History Museum of Denmark, University of Copenhagen: ZMUC-ENT-27. Fig. 1 A,D. Paratypes: SEM preparations are deposited at The Natural History Museum of Denmark: ZMUC-ENT- 28, -29, -30 (Fig. 2 B), -31 (Fig. 2 C). The COI gene of other specimens was partially sequenced and the 710 bp sequence deposited in GenBank (acc. # JQ614997) (Merkel et al. 2012). Etymology: The specific epithet decorata refers to the crenelated latero-posterior edges of the attachment organs of the foot. Description: A medium sized species total length (from the upper edge of the tentacle membrane to the ‘heel’ of the foot) up to about 950 µm. Twelve long tentacles in the adults and ten in the large buds. The width of the tentacle membrane is up to about 400 µm. The body is widest at the median part of the body, up to about 300 µm. From there, the body tapers gradually towards the foot; the lateral parts of the body below the stomach are thin ‘lateral wings’. The foot is up to about 275 µm long. It has a conspicuous foot gland, a foot groove with accessory gland cells, and a pair of rounded adhesive organs at the tip (Fig. 2 B). Two cells of different appearance are associated with each adhesive organ, indicating a duo gland system (Hermans 1983). The adhesive organs are thin with scalloped lateroposterior edges. Buds develop from a pair of latero-frontal zones level with the upper wall of the stomach. Up to two buds on each side have been observed. The largest bud had a total length of about 400 µm; it had ten tentacles. Up to 20 small eggs/embryos, diameter about 50 µm, have been observed in the atrium (Fig. 2 A). The larvae are clearly of the small, planktotrophic type found for example in L. atkinsae (Fuchs & Wanninger 2008) and L. elegans (Nielsen 1971). Discussion: About 120 species have been referred to the genus Loxosomella s.l. (Nielsen 2010; Varela et al. 2011). There is a wide variation of morphology, but a number of characters distinguish groups of species, which are sometimes treated as genera (Iseto & Hirose 2010). The most important characters are found in the morphology and fate of the differentiated foot of the buds, the defining character of the genus (Iseto & Hirose 2010). The attachment of the buds to the parent can be either with the tip of the foot or with the back side of the body. The foot can persist after attachment or be lost after having secreted the cement attaching the specimen permanently to the substratum (variable in a few species, see (Nielsen 1964; Nielsen & Jespersen 1997)). The foot can have a pointed tip or it can have two or four small attachment organs at the tip, or papillae all the way around the foot; it may also have lateral, wing-like expansions. The number of tentacles seems to be rather constant in species with eight or ten tentacles, but to vary in species with higher numbers of tentacles. However species with 12 tentacles in the adults usually attain a stage with 10–12 tentacles already in the large buds, whereas species with higher numbers of tentacles appear to add new tentacles after settling of the buds. The new species has 12 tentacles in the adult and 10 in the large buds. Its buds are attached to the parent with the tip of the foot, which is retained in the adults. The foot is of a type close to that described from Loxoxomella s.str. (Iseto & Hirose 2010; Nielsen & Jespersen 1997), and it shows a pair of characteristic attachment organs at the tip (Fig. 2 B). The foot lacks lateral wings. Among the previously described species, this combination of characters is found only in two species: L. elegans and L. vancouverensis (Rundell & Leander 2012). L. elegans has a prominent Y-shaped row of large cells on the posterior side if the body lacking in the new species and both species lack the characteristic scalloped lateroposterior edges of the attachment organs.Published as part of Nielsen, Claus, 2017, Loxosomella decorata n. sp., a new solitary entoproct from San Juan Island, WA, USA, pp. 594-596 in Zootaxa 4238 (4) on pages 594-596, DOI: 10.11646/zootaxa.4238.4.8, http://zenodo.org/record/37552
Addition formulae for Nielsen numbers and for Nielsen type numbers of fibre preserving maps
No full textAbstractIn this paper we generalize well known product formulae for the Nielsen number of a fibre preserving map, to give addition formulae for such maps. We give necessary and sufficient conditions for when a naïve addition formula expressing the Nielsen number of the fibre map as a simple sum of Nielsen numbers on the fibres is valid. In the second part of the paper we extend to the nonorientable situation the definition and properties of a Nielsen type number of a fibre preserving map introduced by the first author

Carl Nielsen and His Concert for Flute
No full textThis work deals with lesser-known composer (author) Carl Nielsen (living 1865-1931) who lived behind great heritage through his multifarious creation. At first he is advanced towards the readers not only as a composer.His biography desribes the course of his whole life including his private life. The work shows how variety and many-sided is his creation. The work hereafter is focused on his concerto for flute (1926), which belongs to his late and mature work. The concerto is formally analyzed too. Mentioned are the circumstances of the origin of the concerto , its interprets and so on. For the better acuracy of the analyze the orchestral score was used and not only short score. The aim of this work was to raise interest about the personality of Carl Nielsen and to advance him to others readers

No full textWelfare à la growth - A critical analysis of the link between growth and welfare This report deals with the question of which democratic structures that are sustaining the Gross Domestic Product (GDP) as an indicator for measuring welfare, and examines if the alternative Index of Sustainable Economic Welfare (ISEW) is a better tool for this. The examination is undertaken in a critical realistic theory of science, with the inclusion of the work of Tim Knudsen, Peter Nielsen and Herman Daly. The study concludes that the GDP is kept being used because of a consensus of growth, which influences the democracy. Both the state and the political parties are pushing growth maximizing policies through. ISEW is because of its underlining of sustainability and distribution, concluded to be a better indicator for measuring welfare than GDP. However, due to a questionable methodology and subjective assumptions, ISEW is not an ideal welfare indicator.Welfare à la growth - A critical analysis of the link between growth and welfare This report deals with the question of which democratic structures that are sustaining the Gross Domestic Product (GDP) as an indicator for measuring welfare, and examines if the alternative Index of Sustainable Economic Welfare (ISEW) is a better tool for this.
