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
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
EFFECT OF EXCHANGE RATE AND INFLATION RATE ON AGRICULTURAL SECTOR OUTPUT IN NIGERIA
Full text linkThe study examined the effect of exchange rate and inflation rate on agricultural sector output in Nigeria from 1981 to 2020. In other to achieve the objective of this study, the Autoregressive Distributed Lag (ARDL) approach was used to analyse the effect of the data on agricultural sector output. The findings reveal that exchange rate and inflation rate has negative insignificant effect on agricultural output (AGDP) while commercial bank credit to agriculture has positive insignificant effect on agricultural sector output (AGDP) in the longrun. In addition, the short-run results revealed that the current value of exchange rate and its lag value (-2), inflation rate current value and commercial bank credit’s current value and its lag value (-1) have negative effect on agricultural output in the short-run. Similarly, the short run result also showed that the lag values of exchange rate (-1, -3), the lag values of inflation rate (-1, -2 and -3) has positive relationship with agricultural sector output (AGDP)in the shortrun. Consequently, the study recommends among other things that Government should ensure adequate and effective implementation of policies that would enhance stable exchange rates, as effective and prudent management of exchange rate policies will significantly ensure stability of country’s exchange rate (naira). So also government should put in place policy that will help curb inflation. Policy such as selective credit control can be introduced by the central bank of Nigeria with full implementation. As this will help increase production forcing the price of agricultural goods and services to reduce
ANALYSIS OF OIL PRICE, EXCHANGE RATE, AND ECONOMIC GROWTH NEXUS IN NIGERIA
Full text linkThis study examines the nexus between oil price, exchange rate volatility, and economic growth in Nigeria using the Fully Modified Ordinary Least Squares (FMOLS) estimation technique. The findings reveal that exchange rate volatility has a statistically significant negative impact on economic growth, highlighting the adverse effects of currency fluctuations on macroeconomic stability. Inflation also negatively affects GDP, though its impact is statistically insignificant. Conversely, oil price movements exert a significant positive influence on economic growth, underscoring Nigeria's dependence on crude oil revenue. Interest rates also have a significant positive effect, suggesting that stable financial conditions contribute to economic expansion. However, trade openness does not significantly explain GDP variations. The Johansen cointegration test confirms the existence of a long-run relationship among these macroeconomic variables. Based on these findings, policymakers should prioritize exchange rate stabilization through sound foreign exchange policies, increased foreign reserves, and export diversification to mitigate the negative effects of currency volatility. Furthermore, the government should implement strategic policies for managing oil revenues by investing in critical sectors such as infrastructure, education, and healthcare to ensure long-term economic resilience beyond oil dependency. Institutional reforms aimed at improving governance, reducing corruption, and enhancing resource allocation efficiency are also essential for fostering sustainable economic growth
