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
A literature review on information systems support for the cooperation of firms within networks
No full textNowadays, any company wants to gain a clear competitive advantage in the market.
In order to reach this goal it can be important to participate in networks, especially in the case of small and medium enterprises (SMEs). Highly competitive markets require companies to be more flexible, innovative and responsive to their customer needs. In order to access such markets, SMEs need to join forces with others to overcome their limitations through collaboration.
This document deals with Collaborative Network Organizations (CNO). The CNO
concepts are clarified and classified throughout a bibliographic study. Then a three axes representation is introduced in order to map and classify CNOs considering the deepness of the collaboration.Outgoin
Mixed integer programming models for the synchronization of a project building planning with its supply chain
No full textA project consists of a set of activities coordinated by precedence relationships. When this activities have
no needs of resources or the resources are unlimited, project management is easier and techniques like
PERT(program evaluation and review technique)[1] or CPM (Critical Path Method)[1] can be used.
The resource-constrained project scheduling problem (RCPSP) is one of the best known cumulative scheduling
problems due to its combinatorial complexity, the interest of the operational research community, and to its
numerous industrial applications. The basic RCPSP [2], [3] deals with scheduling activities subject to Finish-to-
Start precedence constraints with zero time-lags and renewable resources under the minimum project
completion time objective.
The context of the present research is the industrialization of the process of thermal insulation of buildings by
the outside. The idea is to manufacture in plants highly integrated big panels, that can be easily transported
and then plugged on building faces. . The planning -issue we address here concerns- the possible
synchronization of the project of a building renovation with the plant (or plants) that provide the panels. The
novelty is to move from a “on the building site” make to order production, to a mass customization supply
chain. Therefore, we are seeking for an homogenization of the renovation process to improve its efficiency in
all technical senses but also organizational and economic.
Objectives depend on the manager and his responsibilities in the supply chain. From a plant manager
perspective, it can be the perfect synchronization of the plant production and the on-site assembly in order to
avoid inventories.
In the building project manager idea, it is usually to finalize the project by the minimal possible time allowed by
the precedence relationships, and to minimize the cost of his on-site project.
The differences with the classical RCPSP[4] is that, in this case, the resources to be considered are both
renewable and non-renewable. Moreover the objective function is not only about to finish as early as possible,
as issues such as the synchronization of the project become very important.
Finally the issue is to provide a production planning that is compatible with the delivery of the project and the
availability of resources both renewable and non-renewable.
The former is the part of the problem on the supply chain perspective. The latter concerns the management of
the load on nonrenewable resources, which is moved from the building site to the plants.
Let consider the most general case we consider in this paper: one project of building with various suppliers
with resource constraints. These external resources are independent. It means that every resource has one
different supplier. But, it will be necessary to manage simultaneously the project on-site resources and
partners-plant resources.Outgoin
