What drives Success of Learning Management Systems in Sri Lanka: Student Perspective

Developments in Information technology has made rapid changes in the traditional teaching and learning methods in organizations, such as higher education institutions. This new method of teaching and learning is enabled mainly through Learning Management Systems. Issues in effective implementation and management of such systems have drawn the attention of many researchers. However, LMS success research still lacks particularly in the Sri Lankan higher education context. Hence, the purpose of this research was to examine the success of e-Learning systems in the Sri Lankan higher education context. The conceptual model was tested by fitting it to data collected from undergraduate students using learning management systems. This was the first study to test a multidimensional e-Learning systems success model (DeLone and McLean’s, 2003, IS success model) in the Sri Lankan context. Of the quality dimensions considered, quality of the information/content provided by the system was the most influential. Student satisfaction had the largest effect size on benefits to students. This study provides meaningful insights particularly relevant to e-Learning implementers in higher education in Sri Lanka

A feasibility study for the establishment of a national wildlife health centre in Sri Lanka

Summary Sri Lanka is a tropical nation within a zoogeographic zone that is at high risk for infectious disease emergence. In 2010, a study was conducted on the feasibility of enhancing capacity in Sri Lanka to manage wildlife diseases through the establishment of a national wildlife health centre. The Canadian Cooperative Wildlife Health Centre was assessed as a potential model for adaptation in Sri Lanka. Interviews and group meetings were conducted with potential key participants from the Sri Lankan Departments of Wildlife Conservation and Animal Production and Health, and the Faculty of Veterinary Medicine and Animal Science of the University of Peradeniya. In addition, site visits were made to potentially participating facilities and the literature on best practices in building scientific capacity was consulted. With strategic enhancements in education and training, additional personnel, improvements in transportation and diagnostic facilities, and central coordination, Sri Lanka appears very well positioned to establish a sustainable wildlife health centre and programme

Plasmodium falciparum Malaria Elicits Inflammatory Responses that Dysregulate Placental Amino Acid Transport

Placental malaria (PM) can lead to poor neonatal outcomes, including low birthweight due to fetal growth restriction (FGR), especially when associated with local inflammation (intervillositis or IV). The pathogenesis of PM-associated FGR is largely unknown, but in idiopathic FGR, impaired transplacental amino acid transport, especially through the system A group of amino acid transporters, has been implicated. We hypothesized that PM-associated FGR could result from impairment of transplacental amino acid transport triggered by IV. In a cohort of Malawian women and their infants, the expression and activity of system A (measured by Na+-dependent 14C-MeAIB uptake) were reduced in PM, especially when associated with IV, compared to uninfected placentas. In an in vitro model of PM with IV, placental cells exposed to monocyte/infected erythrocytes conditioned medium showed decreased system A activity. Amino acid concentrations analyzed by reversed phase ultra performance liquid chromatography in paired maternal and cord plasmas revealed specific alterations of amino acid transport by PM, especially with IV. Overall, our data suggest that the fetoplacental unit responds to PM by altering its placental amino acid transport to maintain adequate fetal growth. However, IV more profoundly compromises placental amino acid transport function, leading to FGR. Our study offers the first pathogenetic explanation for FGR in PM
