Renewable energy sources acceptability for decentralized energy system in Nigeria: Issues, challenges and prospects
No full textThe increasing awareness of environmental concerns, coupled with the need to enhance energy security and alleviate the impacts of climate change, has fast-tracked an intensive exploration of renewable energy technologies. The development has indeed recorded remarkable growth in most developed countries like China, USA, Brazil, and China. However, this is not the same as most developing countries in Africa. This work carried out a comprehensive review of the available Renewable Energy Sources (RES) in Nigeria, assessed its level of utilization, identified the challenges, and suggested effective ways of ensuring the adoption of a decentralized energy system through the use of RES. A critical analysis of public opinions on the acceptability of RES as a decentralized energy system in the country was carried out. The work sampled the opinions of people in the adoption of RES for a decentralized energy system using southwest, Nigeria as a case study. The population involves power stakeholders, rural dwellers, RES experts, and policymakers across the six states of southwest, Nigeria. A well-structured questionnaire was designed to capture nuanced responses on a range of key parameters, including awareness levels, acceptance, and perceived benefits and challenges associated with decentralized renewable energy systems. The research findings (through the use of questionnaires) showed a very low level of awareness and acceptability of RES and provided valuable insights into the potential barriers and possible facilitating conditions for the adoption of renewable energy technologies
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
Design of Automated Walk-Through Sanitizing Booth: A Preventive Measure Against Re-Emergence and Spread of COVID-19 Related Diseases
No full text<p> Considering the alarming rate with which the Corona-virus spread around the globe and its devastating effect on the economic, social and psychological well-being of the people worldwide, it is necessary to take measures that may prevent such re-occurrence in the nearest future. The impact of the virus was quite severe, indicating the importance of taking precautions. Realizing the gravity of the situation, governments all over the world, imposed a nationwide lockdown early on, which helped to decrease the possibility of community transmission. However, even after the lockdown, the risk of cross-contamination continues to be a significant concern. This risk was particularly high with asymptomatic individuals who can unknowingly spread the virus without exhibiting serious symptoms. Even now, that clinical trials have demonstrated the effectiveness of some vaccines in reducing mild, moderate, and severe cases of COVID-19. It is necessary to set up preventive measures in combating the occurrence or re-emergence of such pandemic Corona-virus related diseases in the nearest future. A full body sanitizing machine which can be easily constructed was designed in this work. This machine takes the form of a door and tunnel structure, with two sides enclosed by Chaka Plates and two sides open for entry and exit purposes. When a person enters the tunnel, a sensor located at the top center detects its presence and activates the motor, which initiates the entire system. A total of 8-10 sprayers are activated and spray the person's body, automatically stopping after 4 seconds. This machine is capable of sanitizing fifteen people per minute. The discharged fluid and the temperatures of ten individual samples were tested and analyzed in order to ensure that the booth is working effectively. The tested samples confirmed that the tested samples have not been previously infected with the COVID-19 virus. </p>
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
