Fathima Sanjeetha, Mohamed Buhary; Sabraz Nawaz, Samsudeen; Mohamed Hasmy, Abdul Jabbar After this Covid-19 pandemic, there has been a growing invitation for business people and educators to deliver presentations remotely especially through Webinars instead of in person, as the former offers more benefits particularly the ability to reach out to a geographically more expansive audience and the prospects of time and cost savings for the those who host it, resource persons who deliver the contents and audience. To be able to fully leverage on such benefits, effective webinar presentation strategies are needed. In this article, strategies proposed by many scholars are synthesized and presented in eight points that could enrich the effectiveness of webinars in line with the best practices. In overview, the strategies include: knowing the whereabouts, why and how the webinars are organized, empathizing the audience, delivering clear contents and attracting the audience, staying prepared, getting to know the technology, keeping momentum, and weighing the effectiveness of the delivery. In all, it is hoped that these tips would facilitate presenters in improving the efficacy and quality of their webinar presentations.

M. M. P.; Wickramasinghe, D. M. J. Web browsers are amazing. They make the World Wide Web accessible to everyone. People can read web pages by means of web browsers. Many different web browsers are available on the Internet, free of charge. In addition to most popular web browsers that have superb features people might like more, such as faster, free, secure, and different by design, better interface and such. So, people need to take time experimenting with diverse web browsers to find the one they like best if still using the device’s default web browser. This study aims to investigate the factors affecting the selection of web browsers by keeping the straight attention on university undergraduates because, web browser usage has deeply penetrated the academicians not only with their academic workloads but also several purposes. A sample of one hundred and thirty undergraduates who are currently studying in Rajarata University of Sri Lanka selected through stratified sampling technique and research data were collected through structured questionnaire for the study purpose. Descriptive Statistics, Correlation Analysis and Multiple Regression Analysis were used to analyze the data. As per the study findings Browser Performance, Security, Awareness and User Friendliness are the factors need to look at when selecting the web browser to go on. From these results it can be concluded that Browser Performance and Awareness factors were positively and significantly impacted to the Selection of Web Browsers and Security and User Friendliness factors positively but not significantly impacted. The researcher recommends the future researchers to conduct same studies on similar topics, academicians and information seekers for enhance their web browser horizons and web browser developers and technology institutions for provide better web browser products and services by getting the key factors which highlighted in this study in order to their web browsers be the selective web browsers of peoples’ web browser list ever.

Social network usage is massively increasing among children all over the world. School students usually use the latest technology on Social Networks. School students are using social media for several purposes. Usage of Social Networks impacts their studies and everyday life in a fair and bad manner. Several researches have been done in developed countries which can be seen in the literature review. Moreover, most of the studies intended on the effects of social media on the moral behaviour of the youths. Moreover, most of the research considered the undergraduate students' academic performance and their attitudes. The higher probability of no such research on school level students. This study restricted itself to the study habits of the school students. This study aims to collect the data from Advanced level students by a questionnaire which includes the questions on the impact of Social Networks in studies and performance of students. Moreover, this study analyses those data using SPSS to check the students' involvements on Social Networks and impacts on their studies and performance. The result of this research throughout the survey reveals that the performance of studies of school students and the number of social media is negatively associated. Likewise, spending hours on studies negatively associated with spending hours on social media. Moreover, the performance of the students decreases when the spending hours on social media increase.

Big data has gained an enormous success in numerous application areas including social media, economy, finance, healthcare, agriculture, and many more. Now a days, data are being produced at lighting speed. Data produced in many media are either structured, unstructured or semi-structured, using which the researchers could find the unknown pattern behind these datasets. Big Data is one of the most important applications in parallel and distributed systems. Processes related to analysis are often carried out with a deadline and during the process, it is vital for analytics also to concern about the quality of the data. This paper highlights few platform and tools used in the data analytics process. Further, it explains about the several challenges faced in big data analytics. Data representation, data management, data confidentiality and few other are found to be the major challenges in big data analytics. Also, the paper aims to study the technologies applied for big data analysis in the fields of cloud computing, Internet of Things and Hadoop. Finally, the paper reviews on the key application areas of big data analytics by researchers. Fri, 18 Sep 2020 00:00:00 GMT http://ir.lib.seu.ac.lk/handle/123456789/5429 2020-09-18T00:00:00Z
