Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Get PDFWe 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

The Political Economy of the Cost of Foreign Exchange Intervention
No full textCentral Banks around the world increasingly intervene in the foreign exchange market for a variety of reasons, such as maintaining exchange rate stability and maintaining a buffer against the impact of capital flight. In fact, research shows that central banks can lean against the macroeconomic policy trilemma through maintaining reserves and intervening in the foreign exchange market, and thereby secure policy space. However, securing this policy space can come at substantial cost. This dissertation explores the political economy of these costs of foreign exchange intervention. Chapter I discusses the concept of the direct cost of intervention, calculates these costs for several countries over the period 1990–2015, and shows the trends in this cost across countries and over time. This essay shows that foreign exchange intervention and the cost associated with it has increased substantially since the 1990s. Moreover, this cost is higher for developing and emerging economies, countries with more open capital accounts, and countries with less access to a de facto international lender of last resort. Chapter II shifts focus to the indirect costs of foreign exchange intervention. Accumulation of foreign exchange reserves by central banks has meant that they have some capacity to act as a lender of last resort, even when emergency liquidity required is not denominated in their own currency, thereby reducing the probability of default by borrowers in their country in the event of a financial crises. This chapter examines whether the accumulation of reserves due to foreign exchange intervention can be counterproductive by encouraging the inflow of volatile capital flows that are linked to the occurrence of financial crises. Using panel data regression analysis, this chapter finds that episodes of high reserve accumulation are likely to be followed by surges in inflows of capital within one year and five years, and a heightened probability of the occurrence of a currency crisis within five years. However, a higher level of foreign exchange reserve accumulation is associated with a lower probability of systemic banking crises. Finally, Chapter III revisits the importance of institutions that form the global financial safety net in mitigating the costs of foreign exchange intervention. Chapters I and II highlight the importance of access to the global financial safety net, particularly the role played by central bank swap lines with the Federal Reserve in mitigating the costs of foreign exchange intervention. Therefore this Chapter explores the factors that explain the differential access of countries to the global financial safety net, specifically to provision of emergency liquidity by the US Federal Reserve and the Exchange Stabilization Fund of the U.S. Treasury. Specifically, it examines the relative importance of economic and political factors in determining which countries secure access to these de facto lender of last resort operations. This chapter finds that in addition to economic factors like US bank exposure and trade links, political factors like capital account openness, US unemployment rate, defense cooperation agreements, and the party composition of the US government plays an important role in determining access to these International Lender of Last Resort institutions.Doctor of Philosophy (Ph.D.
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe 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

Does Greater Public Ownership in the Financial System Promote Superior Performance?: A Survey of the Literature
No full textThis paper examines whether greater prevalence of government-owned banks leads to qualitatively different outcomes. By reviewing the extensive literature on government owned banks, the paper determines whether greater government participation in the financial system leads to greater financial stability, and greater provision of finance for welfare generating activities. The evidence in literature suggests that the effects of government participation in the financial system are complex and context-dependent. This paper finds that while government banks not only provide finance that privately owned banks fail to provide and finance long-term projects that contribute to the capital development of an economy, they are also a stabilizing counter-cyclical influence in the economy. However, there is evidence to show that in several instances, government- owned banks have been used by politicians for the achievement of political goals. The paper also identifies gaps in the literature on government-owned banks, and avenues for future research
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
