Impact of ICT Adoption and Governance Interaction on Food Security in West Africa
No full textThe impact of the interaction of governance and information and communication technologies (ICT) adoption on food security in West Africa is investigated in this study. The study engaged the system generalised method of moments (GMM) approach on a panel data of 15 West African countries. The data used for the study are obtained from the world development indicators (WDI) and world governance indicators (WGI), for the period 2005 to 2018. The findings show that good governance (government effectiveness and efficient anti-corruption control) can boost food security by between 12% and 20%. Furthermore, the findings show that a 1% rise in ICT adoption may boost food security by 12% to 15%. In explaining the level of food security, the relationship between governance and ICT adoption is positive and significant. This implies that ICT and governance (government effectiveness) interaction may have about 15% positive influence on food security, while ICT and control of corruption interaction may positively influence the level of food security by 8%. The study concludes by recommending that to enhance food security in West Africa, effectiveness in governance and ICT adoption are crucial
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
Green hydrogen hope: How strategic budget allocations translate to emission reductions
No full textGreen hydrogen technology is crucial in reducing carbon emissions and advancing Sustainable Development Goals. This study explores the impact of green hydrogen technology budgets on carbon emissions in the top 10 countries with the highest R&D investment in green hydrogen technology (Japan, Germany, USA, China, France, South Korea, UK, Netherlands, Australia, and Canada) by using data from 2012 to 2023. Unlike previous studies, which depended on panel data techniques and often overlooked the specific economic landscapes of individual countries, this research employs the sophisticated Quantile-on-Quantile method to assess each country's unique patterns and behaviors. Findings reveal a strong negative relationship between green hydrogen budgets and carbon emissions in most selected economies. However, Canada and Australia show a mixed pattern. The findings highlight the need for policymakers to develop tailored strategies that leverage green hydrogen technology to reduce emissions and support sustainable development effectively
From chalk to code: asymmetric nexus between artificial intelligence and educational expenditures
No full textThe rapid advancement of artificial intelligence has prompted significant changes in various sectors, including education. This transformation has led to evolving educational investment as institutions increasingly integrate artificial intelligence (AI) technologies into their teaching and administrative processes. This study examines the asymmetric impact of artificial intelligence on educational expenditures across ten selected nations with advanced AI implementation (USA, China, South Korea, Japan, Germany, UK, Canada, Israel, Singapore, and Sweden). Employing the Quantile-on-Quantile method, the analysis surpasses traditional techniques that may ignore country-specific nuances in panel data research. This approach enables the examination of relationships between variables for each nation individually, thereby improving the accuracy of the findings and providing a valuable understanding of each country’s distinctive characteristics. The results demonstrate that artificial intelligence plays a pivotal role in boosting educational expenditures across most examined countries, each exhibiting distinct trends. These findings underscore the urgent need for policymakers to conduct comprehensive evaluations and develop targeted strategies to navigate the complex relationship between AI and educational investment. By doing so, they can make evidence-based, strategically tailored decisions that address the unique needs of each country
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
