    In the age of globalisation, the educational system has undergone digital transformations in tandem with technological advancements. This change has aided in the creativity of teaching and learning, which is no longer centred on using conventional ideas to aid in students' learning. For the majority of skills, especially engineering, practical experience is appropriately accompanied by theoretical knowledge as part of educational requirements. However, it has been impossible for students to acquire the necessary expertise due to expensive maintenance costs and restricted access to outside facilities. Due to the large number of studies concentrating on 360-degree video as a supporting solution, this project has taken the initiative to investigate the use of 360-degree video as a learning aid, recognising the importance of offering supporting solutions for student learning. As a result, the goal of this project is to develop and evaluate an interactive 360-degree video for the Biomedical Instrumentation course based on the ADDIE instructional model to aid in students' learning. In order to create instructional tools that achieve the optimal educational goal among diploma students of Electronics Engineering (Medical) in Sultan Salahuddin Abdul Aziz Shah Polytechnic, this study modified three learning models and used the ADDIE instructional model. 30 students took part in the evaluation phase by completing the System Usability Scale (SUS) questionnaire to rate the usability of the interactive 360-degree video. Based on the study's overall findings, the majority of students gave the developed interactive 360-degree video system good scores for usability, well-integrated features, and fast learning with the use of an interaction interface. Overall, the findings indicated that the development process of an interactive 360-degree video system was a success, and that it is easily integrated and usable as a digital educational tool for teaching and learning

    Going Beyond Counting First Authors in Author Co-citation Analysis

    The 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

    In this modern world, plants and natural resources are being so significant in various pharmacological and drug research. The search for new antimicrobial and anticancer remedies is among the most prominent research fields nowadays. The aims of the present study are to evaluate the antimicrobial and cytotoxic activity of Sterculiaparviflora against the selected microorganisms and breast cancer cell line (MCF-7) respectively. S. parviflora’s leaves were extracted with n-hexane, ethyl acetate and methanol by using Soxhlet apparatus. At first, the extracts were analyzed for their phytochemical constituents such as alkaloids, flavonoids, saponins, steroids, terpenoids and phenolic. In the antimicrobial screening, the crude extracts were evaluated through disc diffusion and micro dilution methods against two Gram-positive bacteria (S. aureus and B. cereus), two Gram-negative bacteria (P. aeruginosa and E. coli) and two fungi (C. albicanand Aspergillus spp.). In disc diffusion method, the methanol extract exhibited antimicrobial potency against S. aureus and B. cereus which ranged within 8 to 10.7 mm of inhibition zone while ethyl acetate only inhibited B. cereus ranged within 14.7 to 26.3 mm. The Minimum Inhibitory Concentration (MIC) values of methanol extract against both S. aureus and B. cereus is 25 mg/mL while 50 mg/mL against B. cereus for ethyl acetate. The Minimum Bactericidal Concentration (MBC) values which indicated completely inhibition without visible growth of bacteria is at concentration of 50 mg/mL for methanol extract against both S. aureus and B. cereus while 100 mg/mL for ethyl acetate extract against B. cereus. In cytotoxicity study, MTT assay and tryphan blue exclusion methods were done to assess the percentage of viable cells of MCF-7 cell line after being treated with S. parviflora extracts. The results showed that all extracts did not exhibit significant cytotoxic effect on MCF-7 cancer cell line at concentrations of 100, 50, 25, 12.5, 6.25 and 3.125 mg/mL after 24 hours incubation. Moreover, the IC50 values of each extracts also would not be determined due to inability of extracts to reduce the viable cells percentage to be lower than 50%. In conclusion, the S. parviflora extracts exhibited potential antimicrobial activity against S. aureus and B. cereus while possessed no cytotoxic potency against MCF-7 breast cancer cell line

    Variations on the Author

    “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

    We 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

    We 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

    koamabayili/VECTRON-author-checklist: VECTRON author checklist

    No full text
    We 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
