Publication Embargo Unlocking market secrets: Dynamics of the day-of-the-week effect during crisis in an emerging market(Emerald Group Publishing Ltd., 2024-06-17) Riyath, M.I.M; Dewasiri, N.J; Sood, K; Banda, Y.K.W; Nair, KIntroduction: By examining the impact of the day of the week during the COVID-19 pandemic and the subsequent economic recession, it is possible to provide insights into market behaviour during volatile times that can be furnished to investors and policymakers for informed decisions. Purpose: This study investigates the day-of-the-week effect on the Colombo Stock Exchange (CSE), with particular emphasis on the variations in this effect during the COVID-19 pandemic and the subsequent economic crisis. Design/Methodology/Approach: The study applies the Exponential General¬ised Autoregressive Conditional Heteroskedasticity (EGARCH) model, allowing for the evaluation of asymmetric responses to positive and negative shocks. The data span from January 2006 to December 2022 and are segmented into different periods: the entire sample, war and post-war periods, the COVID-19 pandemic and the economic crisis period, each reflecting distinct market conditions. Findings: The study uncovers a significant day-of-the-week effect on the CSE. Mondays and Tuesdays typically show a negative effect, while Thursdays and Fridays display a positive impact. However, this pattern shifts notably during the COVID-19 pandemic, with all weekdays exhibiting significant positive impact, and varies further across different waves of the pandemic. The economic crisis period also shows unique weekday effects, particularly before and after an important political event.Publication Embargo Determinants of dividend policy in the financial sector in sri lanka: A GMM approach(Emerald Group Publishing Ltd., 2024-05-13) Tharanga, T.M.N; Banda, Y.K.W; Dewasiri, N.J; Peiris, T.U.IIntroduction: Why companies pay dividends and the determinants of dividend policy are considered an unresolved dividend puzzle. To reach a consensus over the puzzle, researchers must investigate the factors affecting dividend policy by incorporating all the determinants into a single research effort. Purpose: We examine the dividend policy determinants of Sri Lankan firms, explicitly focusing on the banking, finance, and insurance (BFI) sectors. Methodology: This study uses the quantitative approach applying the Generalized Method of Moments (GMM) system to examine the dividend policy determinants by obtaining secondary data from 51 listed BFI organisations in Sri Lanka. Findings: The analysis disclosed that the variables of changes in revenues, firm size, liquidity, corporate tax, business risk, and profitability have a positive relationship with dividend yield, whereas investment opportunities, leverage, change in revenues, corporate tax, and firm size impact positively on the propensity to pay dividends in BFI organisations in Sri Lanka. Our findings opine that managers in the BFI industries should prioritise changing their dividend policies by paying close attention to factors, such as dividend yield, changes in revenue, firm size, liquidity, corporate tax ratio, business risk, and profitability because the dividend policy is critical to retaining current investors and luring new ones.Publication Embargo AI Applications for Sustainable Development Goals(IGI Global, 2024-01-01) Herath, S.K; Sodige, D.S; Kalupahanage, D.PThe emergence of artificial intelligence and the pursuit of sustainable development are two major forces shaping our world, The need to reorient the existing socioeconomic systems towards sustainability has never been more prescient. The United Nation identified ‘Sustainable Development Goals’, more conveniently known as SDGs, in 2015 as a guideline to fashion a new world that is quite equitable, prosperous and environmentally sustainable by the year 2030. AI can be applied to energy systems in enhancing the use of energy resources, in risk assessment and mitigation of natural occurrences, and in creating new clean technologies. Artificial intelligence is influencing many sectors of society and reshaping numerous industries. This chapter will explore specific examples of how AI is being used to address critical challenges related to the SDGs, discuss the potential benefits and limitations, and examine ethical considerations for responsible AI development and deployment in the context of sustainable development.Publication Embargo Integrated-flexible research methodology: An alternative approach(IGI Global, 2023-03-10) Saliya, C.AThe research process is not a smooth process that moves from one stage to another, or a sequential process growingfrom the roots of ontology and epistemology towards the data collection and analytical techniques and interpretations. The existentialist position of the interpretive / reformist paradigm is that reality is subjective and multiple, that it does not exist independently in the human mind. Their epistemological stance is that the available knowledge depends on the researcher's thoughts and desires. That is, "knowledge" is created by the seeker and deploying a specific methodology which is not necessarily a sequential set of "stages", a "step-by-step" course or a "layer-by-layer" peeling activity like peeling-off an onion.Publication Embargo Analytical network process in decision making(IGI Global, 2023) Jayawardena, T.S.S; Jayawardena, C.SAnalytic Network Process (ANP) is a generalizedform of the Analytical Hierarchical Process (AHP). AHP is an objective theory of deriving the decision makings on absolute scale values starting from subjective relative measurements perhaps on tangible or intangible or a mix of both rated by the experts. A consistency measure of the relative ratings is verified with a consistency ratio to assure the ratings of the experts are consistent. The clustering of criteria/sub-criteria with inner and outer dependencies as well as feedback is taken into account in ANP. In ANP rather than a hierarchical process, a network structure is assumed and all nodes in the network are treated equally with interaction between nodes and grouping into clusters. A supermatrix is constructed, then normalized it to get weighted super matrix and raised it to a sufficient power to converge this into a unique eigen vector representing the final weights in limit super-matrix. Step by step iterations of ANP was demonstrated with a selection of car example.Publication Embargo Research philosophy: Paradigms, world views, perspectives, and theories(IGI Global, 2023) Saliya, C.AThe purpose of this chapter is to summarize the philosophical developments in the academic research field and provide a framework for non-native English-speaking budding researchers. Revealing the philosophical stance of the authors of a research paper is crucial in understanding their arguments. Therefore, an understanding of this historical evolution is useful in justifying authors' choices and presenting them clearly in the research report. Authors' perceptions of different theories, perspectives, and worldviews influence and affect many aspects of research, and it is important to mention personal stances on them in the research report at the very beginning. The choice of underpinning philosophy is significantly influenced by the author's psychosocial, economic, and cultural backgrounds. Multivism is a dynamic position of a researcher who is not confined to the bipolar-disordered extremism of objectivism and subjectivism of ontology, epistemology, methodology, and methods.Publication Embargo Research design(IGI Global, 2023-03-10) Wisenthige, KThe framework of methods and techniques that the researcher has chosen to conduct the research is described as research design. In social science research, it is required to collect evidence relevant to the research problem, especially evidence required to evaluate a problem, to test the theory, or to describe a phenomenon. Successful research designs should be able to provide research insights that are accurate and unbiased. This chapter covers the type of research designs, and names key characteristics of a good research design; neutrality, reliability, validity, and ability for generalization as well as qualitative, quantitative, mix method research, and fix and flexible research designs.Publication Embargo Pragmatism and non-native English speakers: Pragmatism paradigm for social science research(IGI Global, 2023) Nagendrakumar, N; Madhavika, NThe debate of application of research philosophy in social science research is trending. One side takes the positivism while another side depends on interpretivism, some other believes critical realism and the rest stand with pragmatism. Yet, the understanding on and interpretation of ontological argument and epistemological positioning of the pragmatism is criticized. Accordingly, the authors are motivated to critically argue that gap with empirical research evidence from management disciplines in Sri Lanka. The pragmatismfollowers contend that all beliefs, knowledge, and scientific concepts are provisional and defined by their practical application in ongoing experience, not by their correspondence with antecedent truth or reality (Carlsen and Mantere, 2007). Hence, recent social sciences studies are rooted in pragmatic ideas, practice-based approaches thereby harvesting the intersubjective knowledge. Thus, this chapter acknowledges the paradox of whether the definition of pragmatism could be universal or differs contextually research scholars.Publication Embargo Paradigm: Positivism, interpretivism, pragmatists, and critical thought(IGI Global, 2023) Jayasuriya, NThis chapter aims to provide a simple but a complete idea about the difficult concepts in the research field. Research paradigm is a concept which is difficult for new researchers to understand and memorize. This chapter covers the key concepts in the research paradigm: ontology, epistemology, and methodology. Researchers can understand these concept and decide the best paradigm to investigate different phenomena. To make these difficult concepts simple, this chapter has been organized with brief explanations and graphs.Publication Embargo Analytical hierarchical process in decision making(IGI Global, 2023) Jayawardena, S; Gopura R.A.R.CIn the introduction, what decision making is and the significance of the decision making was introduced. Few popular decision-making techniques were listed out and three rational techniques were discussed in a nutshell. Then Professor Saaty's seminal work, Analytical Hierarchical Process (AHP) was described, starting with the evolution of AHP and moving towards its practice through a four-step process. The AHP generates weights on a relative ratio scale with an input of measurements on a standard scale and due to the normalization process linearity of the results was destroyed. Finally, the four-step analytical hierarchical process was illustrated through an example of the selection of a job. During the progression, outcomes of the key theoretical aspects have been touched on without providing proof.
