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
ACTIVE DATA ACQUISITION FOR PROACTIVE EXCEPTION HANDLING IN MANUFACTURING
No full textException handling is increasingly recognized as a critical capability of today's enterprises, especially manufacturers, since manufacturing systems have become complex to satisfy ever-changing customer requirements and support collaboration of various supply chain partners. This paper proposes a concept of proactive exception handling as an advanced approach for effective exception resolution as well as exception prevention. Especially, it proposes active data acquisition as a key element of proactive exception handling. The paper introduces a data acquisition language designed by analyzing the information requirements of active data acquisition. It presents the architecture of a system which enables active data acquisition for the language. Finally, the paper illustrates the language and system architecture using examples. The data acquisition language and system can support proactive exception handling by enabling active acquisition that provides the necessary data only when they are actually required without waiting for the data to be provided.X115sciescopu
Creating a Process and Organization Fit Index: an Approach toward Optimal Process and Organization Design
No full textFitting organizational units to business processes and vice versa is critical to design optimal organizational structures and processes, which is very important for business process reengineering. Business processes and organizational structures are designed separately and independently, however, because there are very few studies to analyze the relationship between them for their effective design. This paper introduces an approach to evaluating the fit between business processes and organizational structures. An index is proposed to evaluate the process and organization fit in terms of the overhead incurred by organizational structures for transfers of work in business processes. Furthermore, indices for relatively evaluating the overall fit are proposed to compare alternative processes and structures. Finally, a case study is presented to illustrate the validity and applicability of the approach. The proposed indices will allow not only the rapid evaluation of alternative organizational structures and business processes but also the identification of problems that cause the lack of fit between them.116scopu
Management of business process constraints using BPTrigger
No full textThis paper proposes a new mechanism, called BPTrigger, which can overcome limitations of current Database (DB) Triggers. DB Triggers are used to enforce integrity constraints related to data stored in databases. They are not adequate, however, for complex business constraints that must be applied to several business processes or activities, hence, involving many data items. Further, DB Triggers does not properly support distributed and heterogeneous environments and may incur serious performance degradation including non-termination. BPTrigger enables representation and flexible enforcement of complex business process constraints in a distributed and heterogeneous environment. Unlike a DB Trigger that must be defined on each data item participating in a constraint and must be checked every time the data item is updated, BPTrigger allows a constraint to be defined only once on a business process and enforces the constraint once at the time of execution of the process. To provide comprehensive support, the paper identifies all possible constraints related to business processes based on literature survey and classifies them into four types: entry, exit, running, and invariant, according to the time of enforcement. Reflecting the requirements suggested by the classification, the syntax of BPTrigger is defined. An additional construct is proposed to enable flexible management of invariants. The paper also introduces a prototype system for BPTrigger along with an extended example to demonstrate its feasibility and to provide a performance comparison with typical DB Triggers.

An architecture for active product configuration management in industrial virtual enterprises
No full textThe importance of configuration management (CM) is increasingly recognised as customers demand safer, higher-quality, and lower-priced products. Although various standards for configuration management exist, there are no internationally agreed standards. Further, existing CM standards do not address the issue of integrating heterogeneous, autonomous, and distributed information, especially for virtual enterprises. This paper proposes an architecture for product configuration management in industrial virtual enterprises. The architecture includes the common objects and functions extracted from various CM standards. Based on the World Wide Web (WWW) and common object request broker architecture (CORBA), it will enable the integration of heterogeneous, autonomous, and distributed information. Further, the architecture adopts a rule concept that will provide an active mechanism for configuration management. A prototype system has been implemented to demonstrate the feasibility of the proposed architecture. The proposed architecture and the prototype will provide a generalised framework and implementation guidelines for CM systems that can shorten the product life cycle, minimise production cost, and guarantee the quality of products in industrial virtual enterprises.X118sciescopu
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
