Publication Embargo The Role of Women on Corporate Boards in Driving Green Product and Process Innovation in Sri Lanka(John Wiley and Sons Ltd, 2026-04-24) Kaluarachchi, SThe purpose of this study is to explore the impact of female leadership on the green innovation efforts of firms in Sri Lanka.Green product innovation was evaluated through the presence of ‘green’ patents, whereas green process innovation was assessedbased on environmental management certifications. This study utilises secondary data from the annual reports of publicly listedcompanies covering the period from 2012 to 2023, applying probit regressions to examine the relationship between female direc-tors and firm-level green innovation. The findings indicate a systematic relationship between female board representation andthe occurrence of green innovation at the firm level. This is evident through factors such as the presence of female directors,female chairpersons, board size, ESG, R&D, firm size and industry type. An additional increase in female representation onboards is more likely to enhance green product innovation, rather than green process innovation. The study provides empiricalevidence that women in top management play a crucial role in shaping a firm's proactive environmental strategies. The findingsoffer valuable insights for enhancing corporate governance with a focus on environmental sustainabilityPublication Open Access Impact of Socioeconomic Factors on Life Expectancy: A Global Perspective Across Income Levels(John Wiley and Sons Ltd, 2026-01-12) Kaluarachchi, S; Jayathilaka, RSocioeconomic factors influencing life expectancy are still underexplored across different income groups in global research. This study investigates the socioeconomic determinants of longevity across global income levels, drawing on World Bank data to analyze how various economic and social factors influence lifespan worldwide. A stepwise panel data regression analysis was conducted to examine the determinants. The findings indicate that increase per capita gross domestic product and health expenditure substantially enhance lifespan, whereas increase population size, death rate, and infant mortality rate adversely impact life expectancy globally. In low-income countries, increase per capita gross domestic product, population size, and death rate significantly shorten life expectancy. In lower-middle-income countries, growing population size and death rate progressively lower life expectancy. In upper-middle-income countries, higher per capita gross domestic product significantly boosts longevity, while increase carbon dioxide emissions, population size, death rate, and infant mortality rate substantially reduce life expectancy. In high-income countries, increase male education significantly raises lifespan, while increase population size and death rate reduce life expectancy. These findings can help policymakers, governments, the World Health Organisation, the United Nations, and the World Bank address key issues affecting life expectancy, promoting global health and sustainable economic growth.Publication Open Access Impact of Socioeconomic Factors on Life Expectancy: A Global Perspective Across Income Levels(John Wiley and Sons Ltd, 2026-01-26) Kaluarachchi, S; Jayathilaka, RSocioeconomic factors influencing life expectancy are still underexplored across different income groups in global research.This study investigates the socioeconomic determinants of longevity across global income levels, drawing on World Bank datato analyze how various economic and social factors influence lifespan worldwide.
