  • Effect of plant growth regulators on micro-propagation of selected Sri
           Lankan traditional and improved rice cultivars (Oryza sativa L.)

    • Abstract: In this study five selected Sri Lankan traditional rice varieties (Kaluheenati, Sulaai, Suwadhal, Dostara Heenati) (Oryza sativa L.) and five improved rice varieties (At362, Bg94/1, Bg358, Bg357, Bg379) were examined for callus induction, plant regeneration and rooting using in vitro techniques. Seeds were cultured in five different hormone concentrations; 1.0, 1.5, 2.0, 2.5, 3.0 mg/l 2, 4- Dichlorophenoxy acitic acid (2, 4-D) and 0.1 mg/l 6 – Benzyl adenine purine (BAP) on Murashige and Skoogs (MS) basal medium for callus induction. Proliferated calli were transferred to five different hormone concentrations; 1.0, 1.5, 2.0, 2.5, 3.0 mg/l BAP with 0.1 mg/l Indole acetic acid (IAA) to regenerate shoots. Regenerated shoots were transferred to three different hormone concentrations; 1.5, 2.0, 3.0 mg/l Indole butric acid (IBA) for rooting. Complete Randomized Design (CRD) was used with ten replicates and data was analyzed by SAS 9.1.3 version. The interaction between plant varieties and different hormone concentrations are highly significant for callus diameter, number of shoots per explants and root length. All tested rice cultivars (100%) were able to produce callus however only 40% of rice varieties were regenerate shoots. The regeneration ability of rice varieties varied from 0% to 100%. All shoots were able to produce 100% roots in tested IBA concentrations. Among all selected rice varieties 2.0 mg/l 2, 4-D+0.1 mg/l BAP is most successful for callus induction while 2.0 mg/l BAP+0.1 mg/l IAA and 2.0 mg/l IBA most effective for shoot regeneration and root induction respectively.

  • A Comparative study for pre and post war performance of Colombo Stock
           Exchange (CSE)

    • Abstract: It is currently debated in academic and other forums that the peace dawning in the country has induced the performance of CSE in Sri Lanka. It is invariably accepted that the smooth functioning of the stock market is largely determined by the stability of the country’s business environment. Thus, this paper attempts to explore whether there is an improvement in the performance of the each business sector listed on CSE in the post war periods. For the purpose of separately highlighting the impact of peace on stock market performance some pre war periods are also considered. The period 2005 to 2008 is considered as pre war period and the period 2009 to 2012 is considered as post war period. To measure the performance of the CSE some important indicators were used namely, sector indexes, market capitalization of the companies, foreign purchases and sales and total turnover of the CSE and key market ratios. Perhaps importantly, these indicators are very widely used in measuring stock market performance by practitioners and academics in developed and developing markets. It is established that majority of the performance indicators used in this study are highly sensitive to the peaceful dividend in the country. Moreover, it is found that majority of indicators have gained significant improvement after the war. The findings imply that peace is an essential element for the development of the capital market in Sri Lanka.

  • Development of new processed mussel product using local mussel species
           (Perna viridis)

    • Abstract: Perna species (Perna perna and Perna viridis) are commonly found edible mussel species around the margin of territorial sea of Sri Lanka It is seasonal seafood available only in few months per year have being experimentally cultured not commercialized as a processed mussel product yet. In this research, three mussels products (321, 654 and 987) were developed only vary with added citric acid amount (3g, 4g and 5g) and organoleptic properties of three citric acid treated bottle mussel products were investigated; nutritional and shelf-life were determined only for best product. Mussels (Perna viridis) harvesting was done in consecutive three days; extracted mussel flesh was stored under -10 0C. The processed product is having net weight of 115 g of cooked mussel and 85 mL of brine solution. Hot filling was done in all the time and stored in the room temperature. Semi trained 30 sensory panelist were used to determine the organoleptic qualities of the products subjectively and the best product was selected through Friedman non-parametric test. The color and texture sensory attributes were shown only the significant different (P<0.05) such as 0.001 and 0.035 respectively; sensory attributes such as appearance, odor, taste, after taste and overall acceptability have received to the P values which may higher than to the 0.05 significant levels (P > 0.05) such as 0.093, 0.152, 0.099, 0.850 and 0.106 respectively. The product 654 has received the highest sum of rank in all the time and considered as the best product. It having 6 months of expected shelf-life; no quality defects recorded until 20th week of shelf-life and having 73.70%, 16.65% and 2.60% of moisture, crude-protein and crude-fat percentages respectively.

  • Employee turnover in manufacturing SMEs in Japan: an analysis of the link
           with HRM practices

    • Abstract: Small and Medium Enterprise (SME) sector is playing a significant role in Japanese economy. However, over the last two decades, SMEs have no longer been a thriving source of growth. The firm entry rate has downward trend while exit rate has trended upward in recent years and considerably exceeded the entry rate. One of the reasons for the high rate of business failures in SMEs, is due to its less attention to the human side of their businesses when compared with their counter parts of large enterprises. High voluntary turnover is considered to be the one of critical problem for SME owner/managers among many other human resource issues. Therefore, the objective of this paper is to examine the relationship between Human Resource Management (HRM) practices and voluntary turnover in SMEs in Japan. Specifically, this study attempts to examine the relationship between HRM practices and voluntary turnover shedding some lights on the mediating effect of the link in between HRM practices and turnover rate. A structured questionnaire was developed and sent to 436 SMEs in Aichi Prefecture and 144 firms responded to the questionnaire resulting in 32 percent response rate. Based on the data analysis it was found that there is negative but weak relationship, partially mediated by HR outcomes, between HRM practices and voluntary turnover rate in manufacturing SMEs in Japan.

  • An Identity of One’s Own: The Use of Sri Lankan English in Ru
           Freeman’s A Disobedient Girl 1

    • Abstract: "… to convey in a language that is not one’s own, the spirit that is one’s own." Raja Rao, Foreword to KanthapuraThe attempt at establishing a form of English with a Sri Lankan identity goes as far back as 1896, with the publication of Glossary of Native & Foreign Words occurring [sic] in Official Correspondence & Other Documents (Gunesekera, 2005: 84), yet its revival after Independence owes to academics of the calibre of Professors H. A. Passé, Doric de Souza and Thiru Kandiah, and Godfrey Gunatilleke, promoting Sri Lankan English. However, it was as late as the early part of this century that the topic became a general subject of interest, with the media and the public being drawn into the debate. Today we see the symbol of the sword ("kaduwa”" ("lvqj")2, gradually giving way to that of the manna ("ukak"),3 as the new generation of Sri Lankan scholars and writers becomes more and more aware of the need for an English of their own. In this article, I shall discuss Ru Freeman's A Disobedient Girl (2009) in the light of this theory.Sabaragamuwa University Journal Vol.13(2) December 2014; 1-22 Published on None
  • Application of Seed Treatments to Increase Germinability of Cardamom
           (Elettaria cardamomum) Seeds under in vitro Conditions

    • Abstract: Cardamom (Elettaria cardamomum) has great commercial value as a spice in Sri Lanka. Due to the presence of hard seed coat, cardamom has low seed germination potential. Therefore the present study was conducted to study the potential to improve the seed germination by applying different mechanical, physical and chemical treatments and to develop a cost effective and rapid seed germination method in in vitro conditions.Complete Randomized Design (CRD) with ten replicates was used for the study. The seeds of cardamom were treated with 40 different seed treatments and surface sterilized by using 20% clorex. MS basal medium was used without plant growth regulators and solidified by 0.6% agar. Anova (DMRT) test showed that there were significant effects at p<0.05 level on seed germination of cardamom seeds with different seed treatments.According to the results 50% HNO3 for 15 min exposure was the best treatment to obtain higher number of germinated seeds (90%) within 6 weeks upto 0.6 cm height. The second and third best treatments were 75% HNO3 for 15 min and 75% HNO3 for 10 min which showed 80% and 65% seed germination percentages respectively. This experiment showed chemical treatment (HNO3) is the best to induce seed germination of E. cardamomum in in vitro conditions. The results obtained in this study will be important for plant breeders and farmers who cultivate these species commercially.Sabaragamuwa University Journal Vol.13(2) December 2014; 23-29 Published on None
  • Chronic Kidney Disease (CKD) in Sri Lanka - Current Research Evidence
           Justification: A Review

    • Abstract: In this article, the current scientific evidence of Chronic Kidney disease with unknown aetiology (CKDu), were critically reviewed and harnessed with other relevant literature with a view to justify the possible causative reason(s) for this chronic health problem. To this end, authors first reviewed the literature on socio-economic, environmental, meteorological, health and geo-environmental/chemical aspects in relation to the CKD of unknown aetiology in Sri Lanka and then studied the known aetiology of CKD (key medical facts) in detail highlighting a comprehensive list of causes. Based on the nature of economic development in the CKDu prevailing area, previous studies have suggested that the causative factor for CKDu is probably environmental and is related to the nature of anthropogenic activities. Therefore, authors investigated subject more into the chronic exposure to heavy metals associated with agricultural activities. Potential sources of heavy metals in the area are mentioned. The geochemical mobility and health effects of three selected elements namely arsenic (As), cadmium (Cd) and Lead (Pb) are studied in detail. The current scientific observations reported on CKD were evaluated with established chemical, geochemical, and health risk of As, Cd and Pb. According to the review, it can be justified that CKDu of the North Central Province (NCP) in Sri Lanka is a decease caused by the chronic exposure and cumulative effects of elevated levels of heavy metals associated with agricultural activities.Sabaragamuwa University Journal Vol.13(2) December 2014; 31-58 Published on None
  • Government SME Development Programs in Sri Lanka: A Review in the Lens of
           Transaction Cost Econo

    • Abstract: The study reviews the government SME development programs of Sri Lanka in the lens of transaction cost economics in order to understand whether they facilitate the development of a favourable transaction environment for SMEs to govern their transaction cost in an economizing manner. Data were collected from the national development plan, strategic plans of the cabinet ministries, which are responsible for the development of SMEs and other publications related to the government national level SME development programs. The study mainly analyses the activities of each SME development program being currently implemented by the Sri Lankan government, employing qualitative content analysis to understand whether they facilitate to access information and to select appropriate governance mechanism. The study recognized that SME development programs of Sri Lanka do not positively contribute to develop a favourable transaction environment for SMEs. The government SME development programs do not facilitate SMEs to access sufficient and reliable information which lead to make more rational decision, to safeguard transactions from opportunism and to select suitable governance mechanism. SME development programs have neglected in supporting formal governance; instead, they encourage relational governance to some extent only for selected SMEs. As a result, there is a high possibility that SMEs in Sri Lanka have a greater transaction cost which averts the growth of SMEs. Therefore, SME development programs need to focus their attention to develop a favourable transaction environment for SMEs providing reliable information which facilitate to make more rational decisions avoiding opportunism on the one hand and to select better governance structure on the other in order to accelerate the growth of SMEs in Sri Lanka.Sabaragamuwa University Journal Vol.13(2) December 2014; 59-81 Published on None
