The demand for safe assets in emerging economies and global imbalances: New empirical evidence
Recent economic theory has singled out mismatches between the supply and the demand of safe financial assets in emerging countries as drivers of international capital flows and, ultimately, global current account imbalances. This paper assesses empirically the contribution of such “search for safe assets” to the size and composition of emerging economies’ international asset portfolios. Excess demand for safe assets in financially less-developed countries would imply that these countries hold disproportionately high shares of their total portfolios in foreign assets. Moreover, financially less-developed countries would hold disproportionately high shares of their foreign portfolios in financially developed countries, which are the major producers of ostensibly safe assets. This paper finds little empirical support for these predictions. Financially less-developed countries allocate a larger proportion of their total holdings to domestic assets. Even when focusing on their foreign portfolios, there is no evidence of a general bias towards the assets of financially developed countries. Overall, asset mismatches do not appear to explain the asset allocation of financially less-developed countries
Going Beyond Counting First Authors in Author Co-citation Analysis
The 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
Russia's gas sector: the endless wait for reform?
The gas industry is perhaps Russia’s least reformed major sector. Prices are regulated, exports are
monopolised and the domestic market is dominated by a state-controlled, vertically integrated monopolist,
OAO Gazprom. Gazprom combines commercial and regulatory functions, and maintains tight control over
the sector’s infrastructure and over information flows within it. The sector as it is currently constituted is
highly unlikely to be able to sustain sufficient output growth to satisfy both rising export commitments and
domestic demand. There is significant potential for accelerating the growth of non-Gazprom production
and making gas supply in Russia more competitive, but this will require fundamental reform. The
proposals for reform advanced in the paper address two sets of issues. First, there is an urgent need to
increase transparency in the sector and transfer many of the regulatory functions now performed by
Gazprom to state bodies. Secondly, there is a longer-term need for a considerable degree of unbundling of
Gazprom. In particular, it would be desirable to remove control of the sector’s transport infrastructure from
the company and to revise the arrangements governing gas exports to non-CIS states, which are currently
monopolised by Gazprom. At the same time, recent increases in domestic gas tariffs must continue until
internal gas prices rise above full, long-term cost-recovery levels
Variations on the Author
“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
We 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
We 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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
We 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
