    BARRIERS AND SOLUTIONS TO ADOPTING DIGITAL TWIN IN SRI LANKAN CONSTRUCTION
    (Ceylon Institute of Builders, 2025) Indunil H.T.T.A; Bandara R.P.H.S; Buddhini P.H.Y.
    In the Industry 4.0 era, Digital Twin (DT) technology has emerged as a key innovation, integrating physical assets with their digital counterparts to enhance coordination, safety, and cost management in construction. Despite its potential, DT adoption in construction remains limited, particularly in developing countries like Sri Lanka, due to high costs, technological barriers, and a lack of standardized integration methods. While DT has significantly improved efficiency in other sectors, the construction industry still lacks practical large-scale applications and a unified framework for implementation. This research aims to explore the applicability of DT in Sri Lankan construction projects. Moreover, semi-structured expert interviews were conducted with 7 experts to gather data. Accordingly, the literature review and insights gathered from interviews highlighted its current usage, benefits, and barriers, and proposed 8 practical solutions to facilitate broader adoption of DT in the Sri Lankan construction industry. The findings of this research are anticipated to contribute significantly to the effective integration of DT technology within the Sri Lankan construction sector. The results underscore the promising role that DT can fulfil in addressing a variety of barriers confronting the construction industry. This study not only emphasizes the critical importance of adopting Digital Twin technology but also seeks to raise awareness of its potential, thereby encouraging its utilization and ushering in a new era of innovation in the Sri Lankan construction industry.

    Sustainability Insights: Unveiling the Impact of Business Analytics in Shaping Sustainability Practices in the Apparel Industry
    (2025) Gajanayake, L; Rajapaksha, D; Rukshan, T; Pathirana, S; Thelijjagoda, S; Pathirana, G
    The Sri Lankan apparels industry has a strategic importance for the national economy as the country has been one of the main exports and employers. But it has sustainability issues such as high resource consumption, increased pollution, and poor labor standards. As the consumption of sustainable and environmentally responsible clothes continues to rise around the world, such concepts as business analytics (BA) present an opportunity to tackle these issues. This study investigates the effects of BA tools and techniques in enhancing sustainability in Sri Lanka apparel industry with regards to waste reduction, efficient resource management and compliance to ethical standards for sustainable driven global business. A qualitative research design was followed and conventional interviews conducted on key informants from GOTS certified apparel factories. Data were coded and analyzed thematically using MAXQDA software, with reference to the subthemes that emerged in the study, such as waste reduction and increasing efficiency and effective decision-making. It was revealed that BA solutions such as RFID, predictive modelling and dynamic dashboards offered promising improvements to sustainability performance. Techniques like 3D sampling reduced fabric consumption during the generation of prototypes, and dashboard analytics allowed constant tracking of other forms of sustainability KPIs like power use and carbon footprint. They also increased efficiency of cross-functional coordination, integrating sustainability into functions and departments. This study demonstrates how BA enables the sustenance of development within the apparel industry, based on a strategic management of economical, ecological, and social goals. The outcomes would help industry leaders and policymakers in developing improved strategies for sustainability practice to overcome existing gaps between theory and practice and for sustainable and competitive business growth in the context of a world economy moving toward sustainability.

    (Emerald Publishing, 2025-04-08) De Silva, R; Henrich, S; de Silva, B.G. R; Maycock, M; Edirisooriya, C; Nagahawatta, K; Medawatta, W
    Purpose – This study aims to explore minority resilience of trans and gender non-confirming individuals within a non-Western, collectivist society in Sri Lanka. Design/methodology/approach – In total, 15 interviews were analyzed with the multi-method qualitative text and discourse analysis framework; by incorporating the depth of discourse analysis with the breadth of thematic analysis. Findings – Four narratives emerged (jealousy and competition; authentic expression; othered or shunned; and conditional acceptance), located at the convergence of the two interview foci, “group membership” and “level of support”. Study findings strengthen the Transgender Resilience Intervention Model with evidence from a non-Western context, highlighting unique findings from Sri Lanka. Research limitations/implications – The sample size, focus on one nationality, exclusion of minors and recruitment of participants with access to digital devices may limit generalizability of study findings. Some responses on autobiographical data required prompting by the researcher, and retrospective recollections may not be reliable. Originality/value – To the best of the authors’ knowledge, this research is one of the first studies in South Asia to explore minority resilience with trans and gender non-conforming individuals. The findings add to the growing body of South Asian scholarship and further expand the predominantly Global North literature by providing a collectivist perspective.

    Unveiling the challenges: exploring start-up hurdles faced by small and medium-sized enterprise entrepreneurs in Sri Lanka
    (https://www.nature.com, 2025-03-30) Gankandage, A; Jayathilaka, R
    This study specifically focuses on the factors contributing to start-up failures in the SME sector in Sri Lanka, with particular emphasis on the educational, socio-cultural, economic, and psychological variables that affect entrepreneurial outcomes. The primary objective is to identify and analyse the factors contributing to these failures. Data collection involved interviews, telephone surveys, and online questionnaires. Given that the dependent variable categorises outcomes as either success or failure, a Probit regression model, was deemed the most appropriate analytical method. The findings reveal significant impacts of educational and economic factors on start-up failures in the SME sector. Additionally, psychological, and socio-cultural factors were found to influence these failures. Most participants recommended integrating entrepreneurship and skill development topics into the O/Level and A/Level curricula. Based on these insights, this study proposes several policy recommendations. It suggests that policymakers improve the education system to meet the country’s educational needs more effectively. It also recommends that family members, society, and religious leaders receive education pertaining to start-up development. Furthermore, it advises policymakers and financial institutions to align more closely with entrepreneurial needs to prevent business failures. Lastly, the study emphasises the importance of educating entrepreneurs on maintaining a motivated and positive attitude, addressing the fear of loss, and understanding the psychological aspects of business management. Building upon the brief overview in the abstract, the following introduction lays the foundation for our study, elaborating on the economic concepts and contextual background.

    (Taylor and Francis, 2024-10-05) Madhavika, N; Bandara, M; Manchanayake, M; Perera, C; Bandara, W; Jayasinghe, P; Ehalapitiya, S
    In today’s construction industry, supply chains are subject to much greater disruption than they were inthe past, resulting in a greater need for resilience. However, there is a gap in the literature that examinesthe resilience of construction small and medium scale Enterprises (SMEs) specifically focusing on develop-ing countries. This article is a step towards identifying the factors influencing the resilience of construc-tion SME supply chains taking the case of Sri Lanka: a developing country which is currently amidst amajor economic crisis. This research study adopted a mixed-method approach, employing 08 structuredinterviews with employees ranging from executive level to top level management of 08 constructionSMEs followed by a questionnaire survey considering a sample of 195 construction SMEs also with execu-tive level to top level management of each construction SME. The findings indicated that Collaboration,Entrepreneurial Orientation (EO), Internal Integration, and Outsourcing have a positive significant impacton the resilience of Sri Lankan construction SMEs’ supply chains during an economic crisis, while‘collaboration’ and ‘EO’ are the most influential factors respectively. Therefore, construction SMEs mustprioritize and enhance collaboration and EO when devising supply chain strategies to strengthen resili-ence during economic crises. This paper contributes to filling the research gap by investigating factorsinfluencing construction SME supply chains in a developing country during an economic crisis. Moreover,it contributes to the knowledge by being one of the latest empirical studies focusing on the constructionSME supply chains in Sri Lanka. The findings provide a valuable reference for both policymakers and prac-titioners seeking to improve the resilience of construction SME supply chains

    Forecasting weekly dengue incidence in Sri Lanka: Modified Autoregressive Integrated Moving Average modeling approach
    (PLoS ONE, 2024-03-08) Karasinghe, N; Peiris, S; Jayathilaka, R; Dharmasena, T
    Dengue poses a significant and multifaceted public health challenge in Sri Lanka, encompassing both preventive and curative aspects. Accurate dengue incidence forecasting is pivotal for effective surveillance and disease control. To address this, we developed an Autoregressive Integrated Moving Average (ARIMA) model tailored for predicting weekly dengue cases in the Colombo district. The modeling process drew on comprehensive weekly dengue fever data from the Weekly Epidemiological Reports (WER), spanning January 2015 to August 2020. Following rigorous model selection, the ARIMA (2,1,0) model, augmented with an autoregressive component (AR) of order 16, emerged as the best-fitted model. It underwent initial calibration and fine-tuning using data from January 2015 to August 2020, and was validated against independent 2000 data. Selection criteria included parameter significance, the Akaike Information Criterion (AIC), and Schwarz Bayesian Information Criterion (SBIC). Importantly, the residuals of the ARIMA model conformed to the assumptions of randomness, constant variance, and normality affirming its suitability. The forecasts closely matched observed dengue incidence, offering a valuable tool for public health decision-makers. However, an increased percentage error was noted in late 2020, likely attributed to factors including potential underreporting due to COVID-19-related disruptions amid rising dengue cases. This research contributes to the critical task of managing dengue outbreaks and underscores the dynamic challenges posed by external influences on disease surveillance.

    Factors affecting job performance of Sri Lankan IT professionals working from home
    (PLOS ONE, 2023-12-12) Jayanandana, N; Jayathilaka, R
    This study investigated the influence of the physical work environment, work life balance, work flexibility, and effective communication on the job performance of IT professionals in Sri Lanka’s IT industry who work from home (WFH). A standard questionnaire was used to collect data from 293 IT specialists in 50 different IT organizations in Sri Lanka, and a stepwise probit model was employed for data analysis. According to the findings, both the physical work environment and work life balance had a significantly positive effect on job performance. A one-unit increase in the physical work environment and work life balance increased the likelihood of high job performance by 0.21% and 0.19%, respectively. In contrast, work flexibility had a negative effect on job performance, with an increase of one unit resulting in a 0.18% decrease in the likelihood of high job performance. The positive impact of effective communication on job performance was less significant. The study emphasises the significance of providing a conducive work environment and promoting work life balance to enhance the job performance of IT professionals in Sri Lanka’s IT industry who WFH.
