No full textImproving project delivery process using lean construction approach
Get PDFThe poor image of the Nigerian construction industry arising from suboptimal performance in project delivery due to colossal wastes is well documented in existing literature. However, effort to proffer solutions to the problems of waste on site has been marginal. After an in-depth literature review it was established that, lean construction approach has been adopted to address waste and non-value adding activities and improved productivity in project delivery. Therefore, this study is aimed at proposing a lean implementation framework (LIF) that will guide the site implementation of lean construction tools to address the waste occurrence menace. Accordingly, action research using mixed-mode approach was adopted, data related to waste occurrences and benefits of lean construction was collected. This was conducted in two phases. The first phase sought to explore the frequency and level of waste and non-value adding activities occurrences in project delivery in Nigerian construction sites. To achieve this aim, data was collected using survey questionnaire administered to 400 experts in construction industry, and tested for internal reliability using Cronbach Alpha. Consequently, the data was analysed using descriptive and inferential statistics and validated using one sample t-test. The results showed the existence of wastes that leads to cost and time overrun. The second phase assessed six lean construction tools via six case study sites. Data was collected through observation, interview, questionnaire and site diary, and analysed thematically using content analysis. The results were validated using methodological triangulation. The results showed that the application of lean construction techniques in Nigerian construction sites could address the problems of waste and non-value adding activities and improve productivity. The study identifies several challenges and barriers that could impede the implementation of lean construction, including lack of knowledge on lean approach, cultural issues, misconception by participants, and lack of involvement of designers in the implementation process. In view of these findings, the study recognises training, enlightenment on benefits of lean, involvement of designers in the implementation process, simplifying the process, trust between the project participants and collaborative planning as strategies for addressing the problems. To facilitate implementation of the suggested solutions to waste occurrences, a lean implementation framework (LIF) was developed to guide the site implementation of lean construction for improving the project delivery process. The LIF was validated using expert opinions by face to face interview, and the result revealed that the framework could be a guide for implementation of lean in construction site
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
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
