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
Diffusion analysis of EFN-MDS structure
Full text linkIn general, block ciphers consist of one top-level structural model into which the round function F is plugged into. The study focuses on Extended-Feistel-Network (EFN) that is a generalization of a Feistel Network (FN). This structure is employed in several ciphers that were developed for Advanced Encryption Standard such as CAST-256, MARS and RC6. The problem with EFN is that it requires many rounds when the number of sub-blocks used in EFN is large. This paper proposed a new structural model that can overcome this problem by incorporating EFN with a linear transformation based on Maximum Distance Separable (MDS) codes. The diffusion analysis shows that EFN-MDS requires at most half the number of rounds to achieve completeness property as compared to EFN structure. Therefore the proposed structure is suitable for designing ciphers with scalable block sizes and ciphers with large block sizes
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
Risk analysis of cyber-campus modules (security guidelines of electronic academic assets)
Full text linkAs the country moves into the Information Age, the use of Information and Communication Technology (ICT) has become a ubiquitous activity in the university departments for academic and administrative purposes. University academic information resources are valuable assets and the security of these assets should be managed properly. Without proper security measures and controls may result in the compromise, improper modification, or destruction of the information resources. This project focuses in outlining the security guideline that can be followed by academic staffs and others who are responsible for the security of electronic information in a university environment. The guideline addresses issues such as choosing good passwords, preventing virus attacks, e-mail security, PC intrusion and administrative responsibilities for the users and administrators who manage computers and networks. Risk analysis technique is used as a guidance in order to come out with the security guideline that is suitable for FSKSM. The guideline is simple and short enough so that it is easy to understand and followed by all levels of staffs. The security guideline formulated can be used as a starting point in drafting a security policy at UTM. With the application of security policy in the academic environment, the security of academic assets can be enhanced and the network as a whole can be trusted
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
Recommended guidelines of electronic academic assets
Full text linkAs the country moves into the Information Age, government agencies including universities are revolutionizing the way they operate. Computer system has become a part of their staff office equipment and most of the information kept is in the electronic form. To make this information useful, it must be accessible when and where it is needed. Now the world trend is towards global interconnectedness and Internet connectivity makes it feasible for information to be available globally. However, managing electronic data as well as connectivity without employing any security measures and controls can result in the compromise, improper modification, or destruction of the information. Disclosure of sensitive information to the wrong hands can ruin and destroy businesses, corporate agency or government. This guideline provides security guidelines to academic staff in the university, and to others who are responsible for the security of electronic information in a university environment. The objective of this guideline is to address issues in the context of protecting electronic academic assets. It discusses some of the threats and vulnerabilities of these academic assets, and some of the security controls that can be employed to reduce the risks
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
