    Small and Medium Size Enterprises (SMEs) are major sources of employment and value creation, as it plays a key role in Sri Lankan livelihood. It is evident that the SME sector in Sri Lanka does not provide the expected results and this sector lacks innovation. Thus, it is important to identify opportunities to improve the SME’s innovative capacity and business performance. This study was designed to investigate the impact of Information and Communication Technology (ICT) on innovations of SMEs in the Western Province of Sri Lanka, and to identify the existing level of ICT usage among the SMEs in the Western Province of Sri Lanka. This study used a quantitative research method. The population of the study was SMEs with less than 500 employees in the Western Province. The sample frame was derived from the two main listings of organizations: the Ceylon Chamber of Commerce and the Ministry of Industries and Industrial Development Board. Accordingly, 350 respondents were selected by using the simple random sampling method. Data were analyzed using the SPSS statistical tool with descriptive and inferential statistics. This study identified four main types of innovations namely: product, process, market, and organizational, and found that there is a significant effect of ICT usage on SMEs innovations. Future research could be undertaken to examine the mediating effect of ICT-based innovations and ICT usage on business performance.

    Validation of a functional screening instrument for dementia in an elderly sri lankan population: comparison of modified bristol and blessed activities of daily living scales

    Abstract Background Cognitive tests have been used in population surveys as first stage screens for dementia but are biased by education. However functional ability scales are less biased by education than the cognitive scale and thus can be used in screening for dementia. Objective To validate Activities of Daily Living (ADL) scale appropriate for use in assessing the presence of dementia in an elderly population living in care homes in Sri Lanka. Method Sinhalese version of the modified Bristol and Blessed scale was administered to subjects aged 55 years and above residing in 14 randomly selected elders' homes. Receiver Operating Characteristic (ROC) was used to determine the cut-off scores of both the scales. Results Based on the ROC analysis, optimal cut off score of the modified Bristol scale was 20 with a sensitivity of 100%, specificity of 74.2% and the area under the curve 0.933(95% CI: 0.871-0.995) while the optimal cut off score of the modified Blessed scale was 10.5 with a sensitivity of 100%, specificity of 71% and the area under the curve 0.892 (95% CI: 0.816-0.967). Conclusion The findings confirm that both the scales can be used in screening for dementia in the elderly living in care homes in Sri Lanka.</p

    Dissecting and modelling the comparative adaptation to water limitation of sorghum and maize: role of transpiration efficiency, transpiration rate and height

    Maize is considered less drought-tolerant than sorghum, but sorghum is commonly grown as a short triple dwarf (3dwarf) type, so difference in plant height confounds the species comparison. The objectives of this study were to experimentally determine effects of species and plant height differences on transpiration efficiency (TE) and transpiration rate per unit green leaf area (TGLA) and use findings to explain input parameters in a simulation study on the comparative adaptation of 3dwarf sorghum and maize in environments with contrasting water availability. Maize, tall double dwarf (2dwarf) and short 3dwarf sorghum genotypes were grown in two lysimeter experiments in 2011 in SE Queensland, Australia. Each plant was harvested after anthesis and total transpiration, shoot and root dry mass were measured to estimate TE. Daily TGLA was used to compare transpiration rates. Species and height had limited effect on TE, but significantly affected TGLA. This was associated with differences in biomass allocation. The similar TE but higher TGLA in maize compared with 3dwarf sorghum meant it potentially produces more biomass, consistent with published differences in biomass accumulation and radiation use efficiency (RUE). The simulation study, which used similar TE for maize and 3dwarf sorghum, but captured differences in TGLA through differences in RUE, predicted crossover interactions for grain yield between species and total water use. The greater TGLA of maize decreased grain yield in water-limited environments, but increased yields in well-watered situations. Results highlight that similarity in TE and differences in TGLA can influence comparative adaptation to water limitation

    Scarcity of high quality feeding materials is one of the major constraints in Sri Lankan dairy industry and the study was conducted to prepare a nutritious, conservable and cost effective cattlefeed block. Four nutritionally diverse feed blocks (B1, B2, B3 and B4) were prepared incorporating different agricultural wastes. Five treatment diets; T1 (only fresh CO3 grass), T2,T3, T4 and T5 (each with 5 kg fresh CO3 + B1, B2, B3 and B4 respectively) were tested in on-farm trial using fifteen Jursey x Sahiwal cross bred heifers. Daily feed intake and live weight gain ofeach animal were measured. Data were analyzed using one way Analysis of Variance in SAS. Among the feed blocks, B3 was prepared with 65% paddy straw, 10% rice bran, 10% coconutpoonac, 10% molasses, 2% urea, 2% salt, 0.5% DCP and 0.5% lime and contained 89.6% dry matter, 14.5% crude protein, 1.5% crude fat, 30.7% fiber, 0.9% Calcium and 0.7% Phosphorus.Average daily dry matter intake and live weight gain of heifers fed with T2, T3 and T5 diets were higher (p<0.05) compared to the heifers fed with T1 and T4. The highest (p<0.05) average dailyfeed intake and live weight gain were recorded in heifers fed with T3 diet. All feed blocks could be kept for 45 days under sealed polyethylene package without any quality deterioration. Thus, block3 could be recommended as the best feed block that to be fed with fresh forages having protein and energy balance at low cost.KEYWORDS: Agricultural wastes, dairy, feed bloc

    Elliptic flow of electrons from heavy-flavor hadron decays in Au+Au collisions at sNN=\sqrt{s_{\rm NN}} = 200, 62.4, and 39 GeV

    We present measurements of elliptic flow (v2v_2) of electrons from the decays of heavy-flavor hadrons (eHFe_{HF}) by the STAR experiment. For Au+Au collisions at sNN=\sqrt{s_{\rm NN}} = 200 GeV we report v2v_2, for transverse momentum (pTp_T) between 0.2 and 7 GeV/c using three methods: the event plane method (v2v_{2}{EP}), two-particle correlations (v2v_2{2}), and four-particle correlations (v2v_2{4}). For Au+Au collisions at sNN\sqrt{s_{\rm NN}} = 62.4 and 39 GeV we report v2v_2{2} for pT<2p_T< 2 GeV/c. v2v_2{2} and v2v_2{4} are non-zero at low and intermediate pTp_T at 200 GeV, and v2v_2{2} is consistent with zero at low pTp_T at other energies. The v2v_2{2} at the two lower beam energies is systematically lower than at sNN=\sqrt{s_{\rm NN}} = 200 GeV for pT<1p_T < 1 GeV/c. This difference may suggest that charm quarks interact less strongly with the surrounding nuclear matter at those two lower energies compared to sNN=200\sqrt{s_{\rm NN}} = 200 GeV.Comment: Version accepted by PR
