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
FlexSIG-Flexible software inspection groupware
Get PDFThe objective of this research is to design and build a groupware system which will allow members of a distributed group more flexibility in performing software inspection. Software inspection, which is part of non-execution based testing in software development, is a group activity. The groupware system aims to provide a system that will improve acceptability of groupware and improve software quality by providing a software inspection tool that is flexible and adaptable. The groupware system provide a flexible structure for software inspection meetings. The groupware system will extend the structure of the software inspection meeting itself, allowing software inspection meetings to use all four quadrant of the space-time matrix: face-to-face, distributed synchronous, distributed asynchronous, and same place-different time. This will open up new working possibilities. The flexibility and adaptability of the system allows work to switch rapidly between synchronous and asynchronous interaction. A model for a flexible groupware system was developed. The model was developed based on review of the literature and questionnaires. A prototype based on the model was built using java and WWW technology. To test the effectiveness of the system, an evaluation was conducted. Questionnaires was used to gather response from the users. The evaluations ascertained that the model developed is flexible and adaptable to the different working modes, and the system is capable of supporting several different models of the software inspection process
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
On-line analytical processing tools for land revenue management system
Get PDFA functional data warehouse organizes and stores all of the available data needed for informational, analytical processing over a historical time perspective. The whole purpose of building the data warehouse is to give an identified set of users a particular set of data. This study is focusing on data analysis tools for tbe land revenue system used by a state government. Land Office is one of the major revenue providers for tbe state government. According to the report provided by the land office in one of the states in 1999, the total income collected through land office was more than RM15 million [61. A system was developed in 1995 to facilitate the collection process. This system is called Sistem Pentadbiran Basil Tanah (SPHT) or Land Revenue Management System. This paper will describe bow a data analytical tool is going to be implemented in the system in order to provide a better mechanism in the decision-making process. New system architecture is proposed in order to maintain the existing system while at the same time providing new analytical processing tools capabilities. Issues regarding the database architecture are also discussed
Challenges in requirements engineering for e-learning elicitation process / Noorihan Abdul Rahman and Shamsul Sahibuddin
Get PDFRequirement Engineering (RE) is a crucial phase in software development process. It is a process to allow users and developers to elicit required information during requirements gathering before implementation starts. Collaborative application is an example of software that possesses knowledge sharing as the main component needed by users in using the application. RE supports software implementation by identifying requirements specification needed for supporting knowledge sharing. This paper gives an overview of requirements elicitation in collaborative application under the umbrella of RE. Thus, Electronic learning domain will be used as an example of collaborative application in order to give the idea of knowledge sharing among users. Electronic-learning can be seen as a collaboration of entities which comprises students, instructors, administrators, designers and developers of the application. Therefore, the challenges of E-learning are also highlighted in this paper in order to depict the importance of RE process for software development purpos
Challenges on e-learning: From requirements engineering perspective
Get PDFNowadays, education offers great flexibility to learners in order to help them to succeed.E learning as knowledge management tool gives service to learners in disseminating and sharing information.Therefore, there is a lot of interaction from users in E-learning community that helps them to solve tasks in E-learning application.There are challenges to sustain
E-learning service because users might get bored and infrequently use it.Requirements Engineering (RE) takes the opportunity to strengthen RE
process by investigating how socio-technical requirements such as lack of social presence, feeling bored and lack of motivation can be transformed as socio-technical requirements and are available to be implemented by developers as agreed by users.Therefore, RE process should manage to capture socio-technical requirements in order to allow consistent motivation among learners.Requirements elicitation, as the initial stage in RE process, may improve its mechanism in eliciting socio-technical requirements for
collaborative application such as E-learning. Hence, RE process and Elearning components must be carefully studied to ensure RE as in Software
Engineering field can assist collaborative application to improve elicitation process and come out with a set of requirements before E-learning is implemented.This paper describes challenges in social interaction issue for E-learning environment and how RE sees these challenges
