Critical success factors for different organizations in construction projects
Full text linkMaster of ScienceDepartment of Civil EngineeringHani G. MelhemResearchers have been compiling lists of key factors the presence or absence of which have determined the success or failure of projects. Early researches of critical success factors were largely theory based; subsequent researches employed the use of statistics and continuously refined methods like neural network and the analytical hierarchy process. Over the passage of time, the focus has narrowed down from broad generalization of ‘projects’ to ‘project classes’.
The thesis can be broadly divided into three components.
First Component: The first component (Chapter 1, 2, and 3) leads an insight into the basic concept of success factor studies, and the empirical frameworks adopted for identification of critical success factors. The second and the third component, comprises literature review and original research, respectively. These components pertain to success factor studies of construction projects, and are introduced as below.
Second Component:
The second component (Chapter 4: Review Component) sets out to choose from among a treasure of resources on construction projects, three such state of the art works that can best explain the progress in search of success factors over a period of the foregoing 25 years. After discussing each work in detail, the reader’s attention is drawn to a collective discussion, and summary towards the end of the Review Component. The review includes the following works: (1) Pinto and Covin, 1989, (2) Ashley et al., 1987, and (3) Kog and Loh, 2011.
Pinto and Covin (1989) endeavored to set aside the convenient research trend of treating all project types (Manufacturing, R&D, Construction etc.) as similar. It was felt that management practitioners considered the generalized project management prescriptions offered by researchers as mostly inapplicable to the unique situations posed by their respective classes of projects. Stepwise regression analysis was employed to seek separate sets of CSFs for construction and R&D projects. The choice of these two project types was made as they apparently lied on opposite ends of the spectrum of characteristics. The phases of project lifecycle considered for
determining CSFs were conceptualization, planning, execution, and termination. It was concluded that though identification of a set of general critical success factors has some benefits for both academics and practitioners, strict adherence to them would not necessarily ensure project success. It was proved that every project type offers its own set of problems, and that these vary over a project’s lifecycle.
The review briefly touches upon the work of Ashley et al. (1987) so as to lead an insight into yet another methodology adopted by CSF researchers. This study views project success from the project managers’ perspective for the owner and contractor organizations they works for, and does not take into consideration the view point of other professionals working for owner, contractor and consultant organizations. Hypothesis testing was employed to find those factors that exhibited strong statistical difference while going from average to outstanding projects.
Kog and Loh (2011) studied a possible dissimilarity between CSFs pertaining to different components of construction projects: (1) civil works, (2) architectural works, and (3) mechanical and electrical works. Using the Analytical Hierarchy Process the CSFs were compared separately for the objectives of budget, schedule, quality, and overall performance. They concluded that, on the whole, markedly distinct sets of factors were perceived as crucial by professionals associated with these three components. Apart from their varying job descriptions, the divergence in views of professionals was interpreted to be an outcome of the different frames of time that they mostly work in. While a major portion of civil and structural works would be undertaken in early project-life, mechanical and electrical works, and architectural works would be initiated later in the project’s life. For the three components of construction projects (C&S: civil & structural, M&E: mechanical & electrical, and architectural works), the highest correlation of views was seen to exist between the C&S and M&E, while the lowest was always that between the M&E and the architect. This trend remained the same whether the goal of overall performance or any of the three objectives were taken into consideration.
Third Component:
The thesis terminates with the original work (Research Component: Chapter 5) conducted by the author in the light of Chua et al. (1999) that had attempted, though very briefly, to distinguish between CSFs for different organizations involved in construction projects. Because the survey sample of Chua et al. (1999) was quite small, the researchers referred to their findings
regarding organization-based CSFs as inconclusive. It was suggested that further research be conducted in this regard. Addressing these recommendations, the ‘Research Component’ has differentiated the CSFs based on organizational backgrounds of project participants: consultants, contractors, and project management organizations.
Spearman’s test on overall rankings of 40 significant factors results in a highest level of correlation between the managers and contractor personnel (rs=0.54), followed by that between the managers and the consultants (rs=0.50), and a least correlation between the contractor personnel and the consultants (rs=0.19). Managers not only maintain a significant presence on the site with the contractors, but also coordinate with the consultants regarding any design-construction issues that arise more than often during project execution: No wonder why their pivotal position helps the managers to establish a higher understanding with both contractor personnel and consultants. The lowest correlation of views between the contractor personnel and the consultants arise from the spot on difference between their workspace environments. Whereas the contractor personnel operate in the field, the consultants are mostly restricted to their design offices
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
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

Author Under Sail The Imagination of Jack London, 1893-1902
No full textIn Author Under Sail, Jay Williams offers the first complete literary biography of Jack London as a professional writer engaged in the labor of writing. It examines the authorial imagination in London's work, the use of imagination in both his fiction and nonfiction, and the ways he defined imagination in the creative process in his business dealings with his publishers, editors, and agents. In this first volume of a two-volume biography, Williams traverses the years 1893 to 1902, from London's "Story of a Typhoon" to The People of the Abyss. The Jack London who emerges in the pages of Author Under Sail is a writer whose partnership with publishers, most notably his productive alliance with George Brett of Macmillan, was one of the most formative in American literary history. London pioneered many author models during the heyday of realism and naturalism, blurring the boundaries of these popular genres by focusing on absorption and theatricality and the representation of the seen and unseen. London created an impassioned, sincere, and extremely personal realism unlike that of other American writers of the time. Author Under Sail is a literary tour de force that reveals the full range of London as writer, creative citizen, and entrepreneur at the same time it sheds light on the maverick side of machine-age literature.Intro -- Title Page -- Copyright Page -- Dedication -- Contents -- Acknowledgments -- Introduction -- 1.
