Approach or Avoid? A Quantitative Study on the Dualistic Nature of Social Media Envy in Undergraduates in a Non-state University in Sri Lanka
(Faculty of Humanities and Sciences, SLIIT, 2023-11-01) Perera, R; Abeysinghe, N; Galappaththi, K
Envy is a complex emotion studied recently, especially with the impact of social media. This study explored the dualistic nature of social media envy in Sri Lankan undergraduates from a nonstate university. Using a quantitative design, data from 155 participants were collected via Google Forms and analysed with Spearman’s Rank test. Results indicated statistically significant positive moderate relationships between social media usage and both benign envy and malicious envy. However, social media only accounted for 20% of benign envy and 8.8% of malicious envy, suggesting it’s only one of many contributors. Furthermore, the association between social media usage and benign envy was stronger than that with malicious envy, implying social media envy may be less severe than perceived in Sri Lanka. The study acknowledges limitations, such as sample size and focus on one university. Future research should address these limitations and explore the dualistic nature of social media envy in different populations and contexts. Overall, the study emphasises the need to understand the complexity of envy and how social media can amplify or alleviate it. Findings have implications for social media usage, regulation, and interventions promoting emotional well-being.

Economy and elderly population, complementary or contradictory: A crosscontinental wavelet coherence and crosscountry Granger causality study
(PLOS ONE, 2023-01-26) Galappaththi, K; Jayathilaka, R; Rajamanthri, L; JayawardhanaI, T; Anuththara, C; Nimnadi, T; Karadanaarachchi, R
The aim of this study is to explore the causal relationship between the economy and the elderly population globally as well as continent-wise. This research was designed as a continent-wide study to investigate the differences between several regions simultaneously. The economy was measured by the Gross Domestic Product (GDP) per capita growth rate while the population aged above 65 as a percentage of the total was considered the elderly population. A panel dataset published by the World Bank for a period of six decades from 1961 to 2020 covering 84 countries was used as data for the analysis. Wavelet coherence was the methodology used for the study since it was considered suitable to present causality as well as the causal direction between the two variables for different sections during the six decades. Thereafter, Granger causality was applied for a cross-country analysis to gain further insights on the causality of individual countries over the years. Findings of the study reveal that the causality and its direction have been changing over time for most continents. Negative correlations with the leading variable interchanging with time are evident for the majority of the regions. Nevertheless, results indicate that in a global perspective, elderly population predominantly leads the economic growth with a positive correlation. Research approach allows ascertaining the short-term and medium-term changes that occurred concerning the direction of the relationship throughout the stipulated period of the study, which could not be drawn by any previous study. Even though region-wise literature is available on this topic, global studies for decades have not been conducted yet.

Exploring the Dynamics of the Elderly Population and Economic Growth: A Comparative Analysis Across Continents
(Springer, 2024-05-30) Jayawardhana, T; Jayathilaka, R; Anuththara, S; Nimnadi, T; Karadanaarachchi, R; Galappaththi, K
This paper explores the cause-and-effect relationship between the elderly population and global economic growth, focusing on different continents. A panel dataset spanning from 1961 to 2020 is utilized, with Gross Domestic Product (GDP) serving as the key measure for economic growth, represented as the percentage change in annual GDP. The study specifically centers on individuals aged 65 and above as a percentage of the total population. The analysis employs a Panel Granger causality test to assess the impact of the elderly population on economic growth. The results reveal a unidirectional Granger causality for Africa and Oceania, suggesting a one-way influence from the elderly population to economic growth. Conversely, instances of bidirectional Granger causality are identified for Asia, Europe, North America, and South America, indicating a mutual influence between the elderly population and economic growth during the study period. The study concludes that an endogenous relationship between economic growth and the elderly population emerges, but notably, this relationship becomes apparent only after an economy has completed its transition in economic development. This implies that the dynamics of the elderly population and economic growth are interlinked, with the nature of their interaction becoming more pronounced in the later stages of economic development.

Impact of Terminal Handling Charges on the Performance of Non Vessel Operating Common Carriers with Special Reference to the 2013 Government Regulation
(Emerald Publishing, 2022-12-01) De Silva, M; Vilasa, S; Bandara, A; Weerasekara, H; Karunarathne, N; Galappaththi, K
: Before the imposition of the regulation, terminal handling charges for containerized cargo were included in the all-inclusive freight listed in the bill of lading and were recovered from consumers at discharging ports. Since the regulation's implementation in 2013, terminal handling charges for containerized cargo can only be recovered from the contractually obligated party to pay them, not from the consumers. In this study, the researchers argue that the former is easier to execute because even though the government has implemented these regulations to secure the consignees and shippers, there are many negative impacts of the regulations on the non-Vessel operating common carriers, as well as indirect impact on the whole shipping industry and the economy of the country. Thematic analysis was used to analyze the data gathered through semi-structured interviews, and thirteen initial codes were identified under three themes during the analysis. Through the findings, the researchers have examined the impact of terminal handling charges in the Colombo port on the non-Vessel operating common carriers after enforcing the 2013 government regulations, analyzed the functions of non-Vessel operating common carriers and their relationship with the major shipping lines, and last suggested the strategies to overcome the negative impact on nonVessel operating common carriers after enforcing 2013 government regulations. This study can guide future researchers and business sectors to construct their plans and processes to ensure that organizations run smoothly and consistently.

A Review on Telecommunication Frauds and Fraud Detection Techniques
(Emerald Publishing, 2022-12-01) Wickramasinghe, Y; Rathnayake, P; Madumal, O; Ramzan, R; Galappaththi, K
Telecommunication fraud is a serious challenge which caused billions of dollars in losses for companies and led to much distress among users. The reported number of frauds has been gradually increasing over the past few years. Hence telecommunication companies tend to use new fraud detection techniques to address the sprawling fraudulent activities. Identification of frauds and application of effective fraud detection techniques are vital for the sustainability of the telecommunication industry. It will drive the industry towards a more credible and profitable direction in the future. This study provides the first systematic literature review on telecommunication frauds and fraud detection techniques. The Prisma method was applied to systematically review the past literature. Using multiple research databases, 1117 research articles were identified, which were screened based on their relevance. 62 articles that were relevant to the study were then analysed in-depth to investigate various types of telecommunication frauds and fraud detection techniques. Results show that the time number of publications is on the rise and citations appear to be saturated at a certain level. The findings emphasise the dire need to investigate fraud happening in developing countries and effective techniques to be implemented to curb fraud. Additionally, a lack of focus on people/qualitative aspects of fraud and detection techniques was identified. The significance of the study is twofold. Researchers could use this study as a steppingstone for future research in telecommunication fraud and fraud detection techniques. On the other hand, Telecommunication companies could refer to this study for understanding fraud and in determining suitable fraud detection method.
