Sustainability of EU public finances
Full text linkWe use a policy rule framework and focus on the response of the primary surplus to accumulated public debt to test a sufficient condition for sustainability. The evidence we report suggests that sustainability was prevalent in many EU countries before Maastricht, but also that the Maastricht impulse induced the shift towards sustainability in some of them. Additionally, although a clear distinction emerges in terms of the visibility of the Maastricht stress between the euro bloc, on the one hand, and the non-euro EU countries, the US and Japan, on the other, there is no evidence of bloc differences in terms of the long term soundness of public finances. On the basis of our analysis and results, we highlight the potential policy relevance of the reaction of the primary surplus to accumulated debt in the debate on the proper balance between fiscal stabilization and discipline in EMU.Stability and Growth Pact, public debt, sustainability, Maastricht, fiscal stabilization, accumulated debt, public finances, sustainability, Ballabriga, Martinez-Mongay
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
Isolation of Ty1-copia putative LTR sequences and their use as a tool to analyse genetic diversity in Olea europea
No full textA DNA fragment putatively belonging to Ty1-copia retrotransposons was isolated from genomic DNA of Olea europaea L., by PCR, using degenerated primers deduced from sequence databases. This fragment includes portions of reverse transcriptase and RNAseH of a copia-like element and has been extended, using chromosome walking techniques, to retrotransposon ends, i.e. the long terminal repeats (LTRs). Ten putative LTR sequences were isolated, and sequence analysis showed that they belong to three different copia subgroups. Putative LTR sequences were evaluated in slot blot hybridisations as to their copy number: only three sequences (Oec04, Oec06 and Oec07), belonging to the same subgroup, were shown to be middle repetitive, with a redundancy ranging from 2.0 × 103 to 2.4 × 103 copies per genome. Southern blot experiments using Oec06 as probe evidenced hybridisation patterns with many weak bands and heavy background smear, indicating genomic interspersion of related sequences. Oec06 was also used to design a primer and to generate REtroelement Microsatellite Amplified Polymorphism (REMAP) molecular markers to distinguish different cultivars of Olea europaea. A total of 108 bands, of which 100 were polymorphic, were obtained. Genetic similarities among cultivars were calculated according to Simple Matching Similarity Index and used to build a dendrogram based on the UPGMA. A comparison between polymorphism based only on retrotransposon sequences and on inter-simple-sequence-repeats (ISSR) showed that polymorphism associated with the former was much higher than that shown with the latter. Our results demonstrate that REMAP markers can be useful in evaluating Olea europaea genetic diversity and in classifying cultivars. © 2006 Springer Science+Business Media B.V
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
