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
Nigeria’s Vulnerability to Global Oil Dynamics and Politics
Full text linkThe paper analysed global oil dynamics and politics and their implications for Nigeria’s development. It adopted systems theory as its theoretical framework and employed the qualitative method as its methodology, in which face-to-face interview was used in obtaining primary data from relevant respondents alongside secondary data from relevant academic works. The paper found out that Nigeria has been negatively affected by the changing dynamics of international petroleum politics, particularly by the fall in global oil prices, as Nigeria depends heavily on oil earnings to meet its budgetary provisions for national development. This is further compounded by mismanagement of the accrued oil wealth before the collapse of oil prices and increased geopolitical tension. Nigeria should without further delay, diversify its economy away from oil to other viable and less volatile sectors, such as agriculture and solid minerals, manufacturing, Information and Communications Technology (ICT), aviation services and so on, alongside the strengthening of its bargaining power in global petroleum politics, particularly in the Organization of Petroleum Exporting Countries (OPEC), availing itself of the advantage of its leadership position in OPEC and the political leverage it has as a strategic actor in international oil politics
Political and Economic Implications of the Russia-Ukraine War for Nigeria
Full text linkThe Russia-Ukraine war, which began on the 24th of February 2022, following Russia’s invasion of Ukraine has upset the relative balance and stability of the world, with implications. It is against this background that the paper examined the extent to which Nigeria has been affected on the economic, political, and social fronts. The paper utilized document analysis for data collection and content analysis for data analysis and discussion of findings. The findings include increase in prices of commodities, resulting in faster inflation and slower economic growth, disruption to industrial activities and agricultural production, foreign exchange crisis and low purchasing power of the Naira (N), disruption to the foreign education of Nigerians, heightened insecurity and reduced political leverage of Nigeria in national and international politics. The paper recommends that urgent and effective measures should be taken to address the identified challenges and a policy should be formulated and implemented to diversify the Nigerian economy
Minimization of the Impact of Globalization on Petroleum Politics: Nigeria as a Case Study
Full text linkThe paper examined the impact of globalization of petroleum politics on the oil sector of Nigeria and Nigeria. The paper employed the qualitative research framework, where document analysis was used method in obtaining relevant secondary data, and thematic analysis was adopted in analyzing the data. It is found that the globalization of petroleum politics has been having both negative and to a level, positive effects on Nigeria, particularly on the political, economic, and social fronts. The negative effects include weakened Nigeria’s capacity to withstand global oil shocks, heightened porosity of Nigeria’s borders and international waterways, and increased loss of oil revenue. Some of the positive effects are increased awareness on the part of Nigeria to do the needful by diversifying its economy from oil to other viable and less volatile sectors, such as agriculture, solid minerals, aviation, manufacturing, and Information and Communications Technology (ICT). The paper recommends that the recently enacted Petroleum Industry Act should be fully implemented, given the derivable benefits for the oil sector, Nigerian state, and economy
The Public Sector in Nigeria: An Exploration of the Role of Nigerian National Petroleum Corporation (NNPC)
Full text linkThe paper explored the role of the Nigerian National Petroleum Corporation (NNPC), a strategically important public corporation in Nigeria, established on April 1, 1977, with the main aim of optimally managing Nigeria’s naturally endowed oil resources with a view to contributing to its socio-economic development, which is expected to have a positive bearing on the standard of living of Nigerians. The paper utilised the qualitative research framework, where secondary data were obtained through document analysis, and it adopted thematic analysis in analysing the data and discussing the findings. The findings include the state of the public sector in Nigeria, which has been found to be poor and the NNPC, even though it is beset by certain challenges, it performs certain strategic functions, which add value to Nigeria’s socio-economic development. The functions include management of Nigeria’s oil and gas resources, supervision of oil production and operations in the oil and gas industry, supply of oil products, investment in sectors that add value to the oil and gas industry and remittance to the federation account for even national development. The paper recommends that the public sector should be strengthened so that it performs efficiently and effectively. This is achievable through enhancing the regulatory frameworks and encouraging PPP (Public Private Partnership). The paper also recommends that the Nigerian National Petroleum Corporation should have a better enabling act to enable it to continue to perform its functions and invest more in value-adding sectors and sustain its interventions in the national life of the Nigerian state, hence helping the state to address its socio-economic challenges
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
The impacts of global petroleum politics and disputes on Nigeria's oil and gas industry towards Nigeria's economy
Full text linkGlobal petroleum politics and disputes have profound impacts on Nigeria, its citizens and economy as well as onto Nigeria as being a member of the Organisation of the Petroleum Exporting Countries (OPEC). This research focuses on analysing the effects of global petroleum politics and disputes on Nigeria's oil and gas industry and thereafter suggest effective measures that Nigeria could take to minimise them. The main questions asked by this study include, what are the effects of global petroleum politics and disputes on Nigeria's oil and gas industry? Why Nigeria is vulnerable to global oil dynamics? How could Nigeria minimise the impacts of global petroleum politics, dynamics and price crisis? These questions are posted to answer the research objectives, which include, analysing the impacts of global petroleum politics and disputes on Nigeria's oil and gas industry; examining the vulnerability of Nigeria to global oil dynamics and finding out the most cost-effective measures to minimise the effects of global petroleum politics, dynamics and price crisis. The research adopted System Theory by Anatol Rapoport as its major theory, while Conflict Triangle Theory by Johan Galtung as its supporting theory. The research employed qualitative method, using both primary and secondary data. The primary data were obtained through purposive sampling and semi-structured interview from thirty five respondents, while secondary data were obtained from relevant books, journal and e-joumal articles, The secondary data were used to strengthen and verify the findings derived from the interviews. The data were thematically analyzed. The research found that the impacts resulted into a devastating economic recession, loss of foreign direct investments,
reduced oil production, destruction of social life and weakened Nigerian state. It also found that Nigeria is vulnerable to global oil dynamics because of its overdependence on oil. The study also found that, the most effective measures to overcome this vulnerability is to diversify the Nigerian economy from oil to agriculture and solid minerals. Another measure is the passage of the petroleum industry bill into law
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
