    (American Society of Tropical Medicine and Hygiene, 2013) Ranasinghe, S.; Wickremasinghe, R*.; Munasinghe, A.; Hulangamuwa, S.; Sivanantharajah, S.; Seneviratne, K.; Bandara, S.; Athauda, I.; Navaratne, C.; Silva, O.; Wackwella, H.; Matlashewski, G.; Wickremasinghe, R.
    Sri Lanka reports significantly more cutaneous leishmaniasis (CL) cases than visceral leishmaniasis (VL) cases, both of which are caused by Leishmania donovani MON-37. A cross-sectional study conducted in an area with a high prevalence of CL prevalent included 954 participants of an estimated population of 61,674 to estimate the number of CL cases, ascertain whether there is a pool of asymptomatic VL cases, and identify risk factors for transmission. A total of 31 cases of CL were identified, of whom 21 were previously diagnosed and 10 were new cases. Using rK39 rapid diagnostic test to detect antibodies against Leishmania spp., we found that only one person was seropositive but did not have clinical symptoms of CL or VL, which indicated low transmission of VL in this area. χ(2) test, independent sample t-test, and multivariate analysis of socio demographic and spatial distribution of environmental risk factors showed that living near paddy fields is associated with increased risk for transmission of CL (P ≤ 0.01).

    (Department of Human Resource Management, Faculty of Commerce and Management Studies, University of Kelaniya, Sri Lanka., 2022) Silva, O.; Siriwardhane, D.; Hettiarachchi, A.
    The objectives of the study were to; examine the differences in happiness at work among white-collar and blue-collar workers in the apparel industry and to explore the main contributing organizational level factors to happiness at work. Following the case study method, a sample of blue and white-collar employees, selected from a large organization in the apparel industry were used to collect data. A structured questionnaire was used to collect data related to happiness and its determinants. Both ANOVA and ANCOVA models together with qualitative analysis were used to analyze data. It was found that blue-collar workers are happier at work than white-collar workers. Furthermore, it was discovered that job inspiration and work-life quality are the most significant contributors to the happiness of blue-collar employees; job inspiration, leadership, and work quality contribute to the happiness of white-collar employees.
