Publication Embargo Contact Tracing Of Covid-19 Patients Using Tweets(IEEE, 2022-02-23) Perera, D; Bamunusinghe, JCovid-19 has had an impact on everyone’s lives in the recent past. Presently the field of healthcare uses social media as a tool for professional education and communication. The benefits and drawbacks of these networks have been widely discussed in different research papers. Due to the Covid-19 pandemic, the biggest problem that the government is facing is identifying the close contacts of the Covid-19 patients. Most of the people avoid revealing the truth about the places they visit and people they met in the recent past to the Covid-19 controlling bodies. But people use social media in their day to day life to post/ share their life experiences. Some people use twitter to share their experiences related to Covid-19. In this research paper we focus on tracing the Covid-19 close contacts using tweets. The proposed approach creates a dataset using a twitter API and filters the covid-19 positive users using sentimental analysis. After filtered positive users from the dataset, we have used a set of keywords to filter individual users’ tweets and then we have applied name entity recognition to identify the connected people and places. After gathering each tweet user’s information, we have visualized the relevant relationships of each close contact in a network diagram. Our proposed model indicates 75% accuracy by tracing down Covid-19 positive users and close contacts.Publication Open Access DOMESTIC VIOLENCE AND HARASSMENT AMONG YOUNG WOMEN DURING THE PANDEMIC SITUATION IN SRI LANKA(Faculty of Management Studies, Sabaragamuwa University of Sri Lanka, 2021-12-16) Michael, K; Vijayan, K; Selvam, M; Liyanage, W.

Although both men and women are impacted, and severity of domestic violence and abuse is substantially higher among women. The World Health Organization has estimated that one-third of women worldwide will experience domestic violence and harassment during their lifetime. The aim of this study is to investigate violence and harassment among young women in Sri Lanka, and sub-objectives are to explore the prevalence of violence and harassment among young women in Sri Lanka. This study is an exploratory investigation with a mixed approach of qualitative and quantitative analysis. For the purpose of data collection, simple random sampling and snowball sampling methods were employed. Through the qualitative approach, the factors influencing personal factors, economic factors, social factors, and relationship factors were identified by the use of past literature.

The study recognized region, family type, husband’s education, husband’s employment, economic pressure, marital type, number of children, culture as the dimensions of domestic violence against women and awareness respectively. The findings designate personal factors, economic factors, social factors and relationship factors have significant impact on domestic violence among young women during the pandemic situation. In addition, proactive control mechanisms are proposed to control the domestic violence and harassment among young women in Sri LankaPublication Open Access Online education during Covid-19 lockdown-Student experience in the non-state higher education in Sri Lanka(National Science Foundation, 2020) Wijesundara, M; Peiris, T. S, G; Thanaraj, T; Peiris, C. NThe objective of this paper is to analyze the effectiveness of online education in both teaching and learning, based on data captured from the Moodle LMS, Eduscope Lecture Video Management System and two students’ feedback surveys at the Sri Lanka Institute of Technology (SLIIT) from January to December 2020. Regression analysis and chi-square test were used as data analyses tools. The data were analyzed using simple linear regression and Analysis of LMS data showed that with each user logging into LMS 3 to 4 times a day with a minimum of 10 user actions per login. The study also found that the percentage of ‘satisfactory’ ratings by students for all aspects considered under four criteria, namely lecture delivery, technology, support services and overall satisfaction exceeded 80% irrespective of the faculty and time of the year. However the students’ responses for individual criteria within four aspects were significantly associated (p < 0.05) by the nature of the faculty. More than 75% of students claimed that the online delivery is working well and enabling them to continue with their studies. No significant difference was found with respect to overall satisfaction by the students between the two periods. The inferences of this study can be used effectively to provide better online education environment in higher education organizations in Sri Lanka. and The infrastructure upgrades, including overall bandwidth, new services including Zoom, Webex and MS Teams, staff training on online delivery enabled a quick transition to online delivery. The incorporation of Respondus lockdown browser and Respondus Monitor online proctoring system further enhanced the integrity of online assessments and examinations.Publication Open Access Impact of online learning efficiency on students' satisfaction and commitment during Covid-19–A concept paper(University of Jaffna, 2021) Ranadewa, D. U. N; Gregory, T. Y; Boralugoda, D. N; Silva, J. A. H. T; Jayasuriya, N. ADue to the fast-spreading of Covid-19, many countries worldwide have closed their higher educational institutes and universities(UNESCO, 2020) and shifted towards online learning methods to continue the education delivery without detaining (Duraku & Hoxha, 2020). The study focuses on analyzing the efficiency of online learning under academic issues, accessibility issues, technological skills of the students, mental well-being of the students, lecturer commitment, and how those will impact on satisfaction and commitment of the students and presents a conceptual framework with the use of empirical studies. Approximately 40 empirical studies have been reviewed for the paper using the keywords. The paper's findings include several gaps related to online learning efficiency during Covid-19: how the academic issues, accessibility issues, technological skills, mental well-being, and lecturer commitment impacted students’ satisfaction and commitment to online learning. Based on the gaps and the findings, the conceptual framework and hypotheses are developed. The researchers directly collect the primary data through a google-form questionnaire that will be used for the study. The questionnaire will be distributed using social media platforms: the undergraduates of government and private sector universities in Sri Lanka. Hence, purposive sampling is used as the sampling strategy, and the results will be analyzed quantitatively using statistical analysis. The paper will be beneficial for future researchers for their references, for the students, and for the educational institutions to provide their students more efficient online education delivery.Publication Embargo ONLINE LEARNING DURING COVID-19: THE IMPACT ON SATISFACTION AND COMMITMENT OF LEARNERS(SLIIT Business School, 2019-12-10) Ranadewa, D.U.N.; Gregory, T.Y.; Boralugoda, D.N.; Silva, J.A.H.T.; Jayasuriya, N.A.The deadly Covid virus has impacted education across the world to temporarily close the educational institutes and shift towards online learning methods (Dhawan, 2020). The educational system in Sri Lanka usually follows the traditional method of in-class learning. Due to the fast-spreading Covid-19 and the government rule imposed on social distancing, the universities across the country facilitated the online delivery of lectures through their learning management systems (Hayashi et al., 2020). Due to this shift, the learners faced several consequences regarding academics, accessibility, and lecturers' commitment. Referring to empirical studies, the study points out how those consequences impacted students' satisfaction and commitment worldwide. Limited empirical studies have been conducted to test the online learning efficiency with regards to learner satisfaction and commitment. Hence, the study aims to investigate whether there is a significant impact between those consequences and students' satisfaction and commitment in the Sri Lankan context. The target population included undergraduates in state and non-state universities in Sri Lanka. The sample size was 384, and the method applied was purposive sampling. The Googleform questionnaire was distributed among the sample, and the results were analysed quantitatively using SPSS and AMOS software, following the multiple linear regression method. The results demonstrate that the academic issues, accessibility issues have a significant negative impact, and lecturer commitment has a significant positive impact on learner satisfaction, and learner satisfaction has a significant negative impact on the learner commitment, proving that learners are less satisfied and less committed to online learning. Considering the originality, this is one of the pioneer studies conducted to identify the impact of online learning on the satisfaction and commitment of Sri Lankan undergraduates during the Covid-19 pandemic. The findings would be favourable for the learners, lecturers, future researchers, universities, and other educational institutes in making solutions to enhance learner satisfaction and commitment.
