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
Policy to promote overseas migrant work: A macro-dynamic framework
Get PDFCould the policy to promote overseas migrant work be to blame for the sluggish development in some South Asian countries? I employ a macro-dynamic model of two small open economies to examine the policy of the developing, labor-exporting country to promote migrant work in a rich, labor-importing economy. The results from calibration exercises show that remittances received from migrant workers are expansionary through its collateral impact. However, the loss of labor due to the policy hinders capital accumulation in the poor country; as a result, it reduces income in the long run. Welfare, however, increases due to the increase in consumption stimulated by the increase in remittances. The impacts are more pronounced for a poorer country such as Nepal whose remittance receipts amounted to more than 30 percent of GDP
ESSAYS ON A SMALL OPEN ECONOMY WITH CROSS-BORDER LABOR MOBILITY
No full textThe dissertation examines the macroeconomic impact of fiscal policy, including a recently-debated remittance tax in a small open economy that exports migrant workers and, at the same time, receives remittances sent by those migrants to families in the home country. The research also investigates the responses of optimal fiscal policy to shocks in either the home or the host country. Then, the empirical exercises are performed to determine the motivations behind remittances. More specifically, we test whether remittances come from existing migrants or result from migration when families at home experience income contraction caused by weather or natural disaster shocks. Chapter 1 provides some interesting findings. First, the results show that an economy with international migration is more resilient to demand shocks resulting from fiscal contraction. Second, the short-run association between remittances and domestic output depends on the sources of the shocks. Third, our results indicate that the equilibrium impact of a tax on remittances can be expansionary and welfare-improving when an economy is initially close to full employment. The presence of utility-enhancing government expenditures and a potential negative externality from over-allocation of labor abroad (over migration) justify the presence of distortionary taxes. Chapter 2 shows that an increase in remittances due to shocks in the host country increases consumption, but reduces domestic output due to labor migration. In such a case, optimal fiscal policy responds by lowering taxes on factor incomes to encourage domestic labor participation and increasing the remittance tax to curb labor migration. However, optimal policy response to shocks in the domestic economy is to raise all income taxes including factor incomes and remittances. Chapter 3 shows that there is no evidence that supports pure altruism hypothesis. Specifically, home income contraction due to natural disasters or weather shocks does not appear to induce existing migrants residing abroad to send more remittances. However, the results indicate that remittances increase as people experiencing the income shocks migrate to earn higher income abroad. The findings support our theoretical specification in the previous chapters that links remittances to international migration
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

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
