Empirical Evaluation of Energy-assisted Protocols for Wireless Sensor Networks
Full text linkWireless sensor networks (WSNs) have emerged as a transformative technology with widespread applications in various fields, such as environmental monitoring, healthcare, and industrial automation. This investigation provides a comprehensive evaluation and comparison of an existing protocol, the Energy-Efficient Backbone-assisted protocol for Load Balancing (EBLBP), against two established protocols: Ad-hoc On-Demand Distance Vector (AODV) and Destination Sequenced Distance Vector (DSDV). Through extensive simulations, we analyzed the performance of these protocols across four critical metrics: scalability, efficiency, network lifetime, and energy consumption. Our findings reveal the inherent strengths and weaknesses of EBLBP, AODV, and DSDV, offering insights into their suitability for various WSN deployment scales and conditions. In the simulation environment, EBLBP achieved an impressive 66.67% reduction in overall energy consumption of 100 to 600 node positions, which underlined its positive impact on energy efficiency. The NS2 simulator was used for this investigation. The measured results validate the advantages of EBLBP in terms of energy optimization
Measuring Dhaka University Students’ Internet Use Behavior of the Department of Information Science and Library Management
Full text linkThis research has been conducted of the undergraduate students in the Department of Information Science and Library Management, University of Dhaka, Bangladesh. A survey questionnaire was developed and used to collect data on students’ demographics, internet use behavior and purposes of internet use in the Department of Information Science and Library Management. The obtained input data were then evaluated using SPSS and the findings have been interpreted. The results showed that students prefer electronic media to printed media in seeking information and they use the Internet mostly to do homework and prepare for their lessons. The students find the quality of easy access of information more important than its other features and they use search engines most in seeking information. The most frequently used search engine is Google. This study discovers what kinds of differences in these behaviors and characteristics may exist between different class ranks
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
Exploring South African digital landscapes : perspectives on academic publishing
No full textPapers presented at BIS Publishing Conference "Exploring South African Digital
Landscapes: Perspectives on Academic Publishing" hosted by the Department of Information Science (Publishing), University of Pretoria on 12 November 2024, Merensky Library Auditorium.The Publishing Studies unit in the Department of Information Science hosted an annual one-day conference on South African publishing. The conference aimed to foster knowledge exchange around the challenges, opportunities, and developments in the academic publishing sector in South Africa, specifically in terms of digital landscapes. The conference had a very positive response, was attended by participants from various sectors such as academic/scholarly publishers, libraries and researchers
A profile of the geographies of students in the Department of Information Science at the University of South Africa (UNISA)
Full text linkIn order for universities to ensure not only access through massification but also retention and success through high throughput rates, it is pertinent that institutions have a basic understanding of students’ contextual realities. Due to emerging political, economic, technological and social developments the nature of the current and prospective university student has changed. This transformation of the university student’s disposition has brought about new demands, anticipations and opportunities. Consequently, these new developments have challenged universities to develop responsive, up-to-date and seamless learning strategies and experiences that will attract and retain students. The purpose of the study is to profile the geographies of students in the Department of Information Science at the University of South Africa (UNISA).The study adopted a quantitative approach and more specifically the informetric technique of data mining to map the characteristics of LIS students in the Department of Information Science. Overall, the study found that there is a scarcity of knowledge about the contextual realities of students registered in the Department of Information Science at UNISA. It recommends that critical information should be collected beforehand to enable the department to align the realities of students with the courseware, the communication technologies and strategies, the pedagogy, and the resources as well as other considerations.Information Scienc
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
