North-South interactions: a general-equilibrium framework for the study of strategic issues
No full textThe model is used to examine the spillover effects of exogenous shocks originating in each of the two blocs. Knowledge of these spillover effects allows the gains from cooperation between North and South in setting macroeconomic policies to be evaluated using the game-theory techniques common in the literature on policy coordination. The model incorporates a variety of North-South linkages. First, commodity prices are forward-looking, and in addition to flow demands for commodities for consumption and production, speculative stocks of commodities are held by Northern investors. Spillover effects occur through the trade balance, and financial markets also link the two blocs: Northern interest rates affect Southern debt payments. In the face of a current-account levy on the South (arising, say, from a fall in aid disbursements from the North), there are gains from cooperation between North and South in devising a joint adjustment programme. However, the gains accrue primarily to the North, and the South faces a strong temptation not to adjust, unless compensated by other means. This suggests the presence of potential gains from cooperation, but gains that may be hard to realise
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
Synthesis and properties of alkali-metal lithium periodatoferrate(III) and periodatocobaltate(III) complexes
No full textThe pale-yellow LiMFeIO6 (M = K, Rb or Cs) have been prepared by reaction of MIO4, Li+ and [Fe(H2O)6]3+ in hot aqueous solution at pH 9. Olive-green LiMCoIO6 were prepared from MIO4, Li+ and [Co(H2O)6]2+ in hot alkaline solution using ozonised oxygen as oxidant. These insoluble powders have been characterised by analysis, IR and Raman, UV-VIS and EPR spectroscopy and magnetic measurements. PXRD studies revealed that they are amorphous, but structural data have been obtained via Fe or Co and I K-edge EXAFS, and are consistent with a layered periodate structure type similar to that found previously in MM′IO6 (M′ = Mn, Ni, Ge, etc). 57Fe Mössbauer data are reported for LiKFeIO6.</p
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
