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
The Impact of Coronavrius on Health and Economic Growth in Sub- Sahara Africa
Get PDFHealth enhancement is an essential determinant of economic growth; though, the impact of health on economic growth is affected by the level of poverty in any country. This paper, therefore, examined the impact of health on economic growth during corona virus in Sub-Sharan Africa and the verge of health required to alleviate the adverse effect of poverty on economic growth in Twenty (20) selected Sub-Sharan Africa countries. Based on the endogenous growth theoretical approach, the link between life expectancy, poverty incidence, and economic growth was estimated using the GMM technique of analysis. Findings showed that coronavirus pandemic exerts negative impact on health condition, household welfare, unemployment and the adverse effect of poverty on economic growth in Nigeria. Though government expenditure significantly increased during the period in a bid to check the pandemic, but household welfare degenerated and was negatively affected with high poverty rate, this paper recommended that the government of the Sub-Saharan countries should diversify the revenue base of their economies to cushion the effect of unprecedented shock due to the pandemic and provide adequate relief materials to pad the effect of loss of income to the poor and vulnerable, invest in the health sector to control infectious and pandemic diseases.

FOREIGN DIRECT INVESTMENT, TRADE OPENNESS AND ECONOMIC GROWTH: EVIDENCE FROM NIGERIA
Get PDFThe globalization movement, which presentsenormous prospects for the majority ofdeveloping nations to achieve quickereconomic growth through trade andinvestment, has greatly expanded theimportance of foreign direct investments(FDI) over the past few decades. FDI helpsforeign investors make better use of theirresources and assets, and it also helps hostnations gain access to superior technologyand join global production and commercenetworks. This paper examines the dynamicand interrelationship among FDI, tradeopenness and economic growth in Nigeria.Annual time series for Nigeria from 1980 to2020 was analyzed using the dynamicClassical Multiple Linear Regression Model,also a pre-estimation test of unit root was firstconducted using two approaches. The resultshows that a 1% increase in FDI would havethe reverse effect on economic growth,reducing it by 19% annually, with all otherparameters being constant. It demonstratesunfavorable trends for foreign directinvestment and trade openness,demonstrating a weak correlation betweenthese variables and the Nigerian economicgrowth index. Another component of themodel that has dynamic long-term impacts oneconomic growth is the historical growthtrajectory. The results imply that the mostrecent adjustments to Nigeria\u27s economicindicators have an effect on the present set ofeconomic growth. In order to encourageexports and FDI inflow and to create abusiness environment that will supportNigeria\u27s output growth dynamics, the essaysuggests expanding trade liberalization. Inorder to allow indigenous enterprises to fullyengage in the global economy, it was also
suggested that Nigeria\u27s government developpolicies to broaden the scope of foreign trade
Assessing the Socio-Economic Impact of Coronavrius in Africa
Get PDFThe looming health shock of coronavirus could have disastrous impacts on the continent’s already strained health systems, and could quickly turn into a social and economic emergency. This paper, therefore, intends to assess the effects of coronavirus on Africa economies. (using its growth implication) Based on the endogenous growth theoretical approach, the link between life expectancy, poverty incidence, and economic growth was estimated using the GMM technique of analysis with 32 selected Africa countries. Findings showed that coronavirus exhibited negative and substantial impact on socio-economic situation and macroeconomic variables in Africa such as inflation, unemployment, poverty rate and economic growth, amongst others. The result ascertained that the government expenditure significantly increased during the period in a bid to curb the pandemic, but household welfare degenerated and was negatively affected with high poverty rate, this paper recommended that the government of the Africa countries should diversify the revenue base of their economies to cushion the effect of unprecedented shock due to the pandemic and provide adequate relief materials to pad the effect of loss of income to the poor and vulnerable, support in the implementation of structural reforms to enable them to build capacity and generate sufficient domestic resources or fiscal buffers to effectively manage pandemics.

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
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
THE EFFECT OF TRADE OPENNESS ON POVERTY IN NIGERIA
Get PDFThis study examines the effect of trade openness on poverty in Nigeria. The study adopts autoregressive distributed lag (ARDL) model to study the relationship between poverty and trade openness and other explanatory variables. Measures of poverty used for this study were per capita income and human development index. Consequently, two autoregressive models were specified and estimated in order to examine the effect of trade openness on these two measures of poverty. In the two models, trade related variables (exchange rate and foreign direct investment) were included in the model as explanatory variables along with trade openness which is the key explanatory variable in the two models. The result of the analysis shows that in the first model trade openness has significant positive effect on per capita income only in the long run, foreign direct investment has a positive effect on per capita income both in the long run and in the short run while exchange rate has a negative effect on per capita income in the short run. In the second model, trade openness does not have a significant effect on human development, foreign direct investment has a significant and positive effect on human development while exchange rate has a significant negative effect on human development. It is recommended that the government should ensure that trade policies are mutually beneficial to Nigeria and the trading partner and that some specific bilateral trade relations are well negotiated. It is also recommended that the government should create the enabling environment to attract foreign direct investment into the Nigerian economy because of the positive gains on poverty reduction as shown in the findings
