Review on lean principles for rapid construction
No full textThe general approach within lean construction is to make the construction process as it is normally undertaken on the construction site and leaner by reducing non-value generating activities. The reason on why the lean principles are used into rapid construction is to solve the chronicle and
congested activities within the time frame of the rapid construction projects. Five principles of lean
were made into comparison in the review of three case studies. In many applications of construction concept, the use of rapid construction method components significantly decreased the construction time required for the project. The most significant benefit has been seen in areas where systems have been using it repeatedly. The benefits from lean principles into rapid construction are the shorten of order fulfillment leading times, less project downtime, more innovation and true reduce the chronicle predecessor. This research has also identified eight critical factors of integrating lean with rapid construction that are proven successful which are planning it right, understanding the whole life construction cycle in non price factor view, utilize knowledge and expertise, integrate the team by working with the end to end supply chain in an integrated manner, understand the end to end process, measure performance to include reporting in your own performance, training and benchmarkin
Practicing lean in sustainable construction to achieve time reduction
No full textImplementing new management philosophy in construction became an approach for construction players in achieving optimum output of the process. The practice of eliminating non-value added in the construction process flow is important in creating the elements of time reduction. Therefore, lean is the best approach as a management philosophy to be adopted in construction process flow because of the stabilizing and pulling factors towards construction time reduction. There are few cases being observed and non-value added activities being analysed accordingly to lean approach. From the questionnaire survey, factors of waiting, overproduction and double handling became the most prolongation of the construction time that contributes to delay. The analysis proof that leans has the factor of time reduction and contributes to rapid construction. The construction process flow became stable and the minimum cost being pulled in the construction cycle
Level of acceptance towards industrialised building system (IBS) in Malaysia
No full textConstruction practices towards conventional method is still being practiced widely even there were many researchers have done the studies on the inefficient of that method. On the other view, innovative construction had been the solution to improve the construction process flow. The need for innovation in construction industry is to enhance the efficiency for the success of project delivery. This could change the paradigm of norm construction practice which depends on conventional methods and a lot of non-value adding activities occur on that process flow. Industrialised Building System (IBS) is a method introduced to Malaysian construction players and it seem significance to the industry. This concept creates a new improvement for the successes of construction project by emerging techniques and materials in efficient way. This study shows the level of acceptance toward IBS concept comparing with conventional method. Interviews and questionnaires survey were done in getting data and analysed to get the factors relating time reduction, wastage and barriers of implementing it. Result shown the perception of construction players for IBS and it will provide to all parties the credits in choosing IBS concept for the project
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
