A structured approach to managing technical process reengineering projects
No full textThe emerging knowledge-based economy has pointed out theimportance of competence and its interface in the conception of
any economic process. There has been a natural evolution in industrial innovation processes: from a sequence of separated phases
(sequential approach) to a multidisciplinary network of competences (interactive approach). These changes have brought about the
increase in the information to be managed and coordinated especially if the project regards processes such as reengineering ones in which
the technical aspects are predominant and critical. The aim of this paper is to propose an integrated methodology based on a logical
framework which guarantees effective analysis and management of data generated during a project of Product/Process Reengineering
(PR). The framework is able to coordinate these information flows whose complexity is related to the different nature of the data
involved, by supporting design and operation processes during the evaluation of all the feasible alternatives
Steering projects through simulation: an innovative tool to improve projects guidance efficiency
No full textA project plan hardly reflects what actually happens
during the project mainly because it tends to be static,
while nowadays projects are extremely dynamic.
Moreover, the strong integration between the executing
and the planning phases makes the projects guidance
very hard, especially under strict time boundaries. The
existing project management techniques are quite
inadequate to handle these features. For this reason, the
paper proposes an innovative tool able to guarantee an
improvement of projects guidance efficiency by
introducing the simulation into the time-cost trade-off
analysis. The model on the basis of which the tool has
been developed uses in an integrated manner different
operational software: Microsoft’s Project, Visual Basic
for Application and Rockwell’s Arena. The tool has
been tested on a construction project in progress and has
already proved its usefulness in the planning as well as
in the executing phases
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
Improving project control and guidance through a time-frame simulation approach
No full textNowadays projects dynamicity and complexity make the control process highly critical. The existing planning and control techniques have frequently proved inadequacy to manage the present challenge. The paper proposes a simulative approach to managing with more effectiveness projects life cycle. The appositely developed simulation model is populated with both deterministic and stochastic elements: the formers come from the project plan; the stochastic elements have been introduced in order to consider the probabilistic nature of activities duration. In the planning phase the model generates a "baseline pencil" that gives a more confident estimation of the time to complete the project. During the execution phase the model is able to store the data related to the ongoing activities and updates in real-time the estimation of the project completion. Concurrently, it allows the calculation of specific performance indexes which permit to identify in real-time possible occurring "warnings" to users and suggest potential solutions
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
