Stratification Pattern and Geochemical Distribution of Gem Mine Sediments in Rathnapura Gem Fields, Sri Lanka
No full textThe geomorphic history of Sri Lanka originates in the Precambrian, when the basement rocks were formed, while the much more recent events of subsequent weathering, erosion and sedimentation processes that led to the development of gem-bearing strata. In the hill country, mineral-rich sediments were carried by rivers and streams and deposited in depressions and floodplains, creating favorable conditions for gem concentration. This study investigates the stratification of gem deposits in the Ratnapura region, focusing on how sediment depth, particle size distribution and geochemical signatures reflect long-term geomorphic and climatic dynamics. Ten gem mines were examined to assess vertical and lateral variations in sediment characteristics. Results show that stratigraphic layering corresponds to Quaternary climatic oscillations, with alternating wet and dry phases producing two to three distinct gem-bearing horizons at varying depths. Geochemical analysis indicated relatively stable concentrations of P₂O₅ and CaO, while K₂O, MgO and Fe₂ O₃ showed considerable variability. Grain size decreased with depth, with higher clay and silt proportions suggesting deposition in low-energy basins, whereas sandier deposits reflected higher-energy fluvial transport. Variations across sites point to the influence of paleo-river channel shifts and localized geomorphic processes.

Obstructive Sleep Apnea and Associated Risk Factors among Managerial and Senior Executive Level Workers in the Western Province of Sri Lanka
No full textIntroduction: Obstructive sleep apnea (OSA) is a highly prevalent, yet underdiagnosed potentially serious sleep disorder identified worldwide. The present study aimed to assess the risk factors associated with OSA among the managerial and senior executive level workers, who work in demanding work environments. Methods: A web based, cross-sectional study was conducted using data of 390 study participants, comprising managers, senior officials, and legislators selected through cluster sampling in the Western Province, Sri Lanka. Berlin Questionnaire (BQ) was used to assess the OSA risk and demographic and associated factors of participants were surveyed in another section of the semi-structured questionnaire. Associations between risk factors and OSA were evaluated using logistic regression analysis by SPSS 26.0. P<0.05 was considered significant. Results: BQ identified 20.8% of participants as being at high-risk of OSA, whereas 79.2% were classified under low-risk. Males were more likely than females to develop high-risk OSA (26.6%vs11.3%, P=0.001), and those in the high- risk category were predominantly middle-aged (41-60 years) men (48.1%). Further, BMI (p=0.001), neck circumference (p=0.044) and alcoholism (p=0.009) had a positive correlation with high-risk OSA which was statistically significant. However, there was no significant association between smoking status and high-risk OSA (p=0.155). There was a significant relationship between the comorbidities, diabetes (p=0.007), stroke (p=0.006), hypertension (p=0.001) and OSA risk except for heart disease (p=0.412). Conclusion: Among category one occupants in the Western Province of Sri Lanka, 20.8% were at high-risk for OSA. Male gender, middle age, obesity, increased neck circumference, alcohol use, and comorbidities like diabetes, stroke, and hypertension were significantly associated with OSA.

The Influence of Destination Image on Tourist Satisfaction and Word of Mouth Intention: A Literature Based Analysis
No full textDestination image plays a critical role in shaping tourist satisfaction and behavioral intentions such as word-of-mouth (WOM) communication. This study conducts a qualitative content analysis of existing theoretical and empirical studies to explore how cognitive, affective, and tangible components of destination image influence tourist satisfaction and WOM intention. Using the Stimulus-OrganismResponse (S-O-R) theoretical framework, this analysis highlights the multidimensional structure of destination image and its direct and indirect effects on tourist behaviors. The study synthesizes key conceptual frameworks, identifies research gaps, and proposes a conceptual model for future research. Findings emphasize that a favorable cognitive, affective, and tangible image collectively strengthens tourist satisfaction, leading to enhanced WOM intention.
 
Transit-Oriented Development and Sustainable Urban Growth: A Review of Key Influencing Factors
No full textTransit-Oriented Development (TOD) is a strategic urban planning approach aimed at creating highdensity, mixed-use communities anchored by public transit systems. TOD seeks to reduce car dependency, improve urban livability, and promote sustainable growth. This paper reviews existing literature to identify critical factors that influence TOD success, including land use planning, accessibility, walkability, governance, and social equity. The paper incorporates international case studies from Indonesia, Dubai, United States, Japan, the Netherlands, Brazil, and India to analyze how different cities have applied TOD principles. The study finds that successful TOD requires a contextsensitive, integrated planning approach supported by proactive governance, community engagement, and inclusive policies.
 
A study of the ruler - public relationship as reflected in the Mitrabedha of the Panchatantraපංචතන්ත්රයේ මිත්ර භේදයෙන් පිළිබිඹු කැරෙන රාජ්ය පාලකයා සහ සේවකයා අතර ඇති සම්බන්ධතාව පිළිබඳ අධ්යයනයක්
No full textThe Panchatantra, considered the pinnacle of Sanskrit upadeśa literature, is a work by the scholar Viśnuśarman, believed to have been composed when he was eighty years old. It is believed to have been written in the 3rd-4th century CE. It was written in the style of storytelling with the aim of giving advice on state law to the three sons of the king Amarasakti of the city of Mahilaropya. It has five tantras or chapters, namely Mitrabedha, Mitrasamprāpti, Kākolukīya, Lababdhapraṇāśa and Aparikiśitakāraka, the first Tantra of the Panchatantra, contains about 20 stories of the separation of friends, and its main purpose is to break friends and thereby seize power. The research problem here is how the relationship between the ruler and the servant (sevya-sevaka) is used for good governance. The main purpose of this research was to analyse the role of the ruler and the servant, and to examine how their relationship contributes to good governance. In this research, which was conducted based on qualitative data was collected through the methods of primary and secondary sources and interviews. The method of detailed information analysis was also used. The data was collected through the methods of using the source and interviews as a tool. The method of analysing the information in detail was also used. The role of the king and the state servant can be clearly shown through the contents of the Mitrabedha Tantra. The king, who is the head of the state, becomes the king from father to son, brother to brothers or by winning wars. The king becomes a high figure because many people associate with him. Viśnuśarman has seen a parallel between kings and snakes in this. The job of the servant is to provide the king with his best service. The qualifications required to become a servant of the king, and the basic principles of state governance are also included here. The difficulty of public service is mentioned here because they have to act in accordance with the royal orders. But the author of the Panchatantra, who says that even Brahmins who perform sacrifices cannot perform such a noble service, implies that the public servant is a person of high character. The analogy of the wheel shows how the relationship between the sevya-sevaka should be. A country can be governed by the mutual harmony and understanding that arises between them. It is thus clear that for the good governance of a state, the relationship between the sevya- sevaka should be at a very high level
Relationship between Financial Literacy and Business Performance: Empirical evidence from small and medium enterprises (SME) in Sri Lanka
No full textThe purpose of this study was to determine the level of financial literacy in Sri Lanka based on demographic factors and to identify the impact of financial literacy on the business performance of small and medium enterprises (SMEs). As a result, a quantitative study based on Prospect Theory and Exchange Theory was conducted. In Sri Lanka, there is a shortage of studies on these variables. This research is being carried out in order to close the empirical gap. The sample size was 100 SMEs in Sri Lanka, and the required data was collected using the usual purposive sampling method. After conducting factor analysis, reliability, and validity tests, this study used primary data from questionnaires. Since the previous empirical review suggested using this analysis to examine the relationship, the objectives were achieved through descriptive analysis, correlation, and regression analysis. The study's findings revealed that financial literacy and business performance have a positive relationship. As a result, independent variables such as technical financial knowledge, financial market knowledge, and financial management skills impact SMEs' business performance, with technical financial knowledge and financial management skills being the most influential of these variables. This study concluded that good financial knowledge among owners is required to make decisions to explain prospect theory. This study also found that owners and employees should have a higher level of education. According to the exchange theory, it should exchange information or knowledge among employees and recruit more skilled employees. The study gives SMEs and policymakers insight into how financial literacy can help them make better decisions and improve their businesses performance. As a result, business owners and policymakers should set up training programs to improve financial literacy knowledge.Keywords: Financial Literacy, SME’s, BusinessSME’s Performanc
Reflection of Cultural Identity in English Translations of Sinhala Literary Writings: with Special Reference to the Trilogy of Martin Wickramasinghe and its English Translation
Get PDFPreserving cultural identity is the utmost challenge in translating literary texts embedded with cultural capital. Cultural capital is untranslatable, yet it can be depicted by replacing equivalents of the target language. However, the effectiveness and applicability of equivalents that belong to a different culture are problematic. The main purpose of this research was to study how effectively cultural identity is reflected in the English translations of Sinhala Literary texts with reference to the great trilogy written by Martin Wickramasinghe. Thus, the study investigated what strategies were used by the translators to preserve and depict the cultural capital of the source texts and how effectively they are used to reflect the cultural identity. The methodological structure of the research is qualitative, and the relevant primary data was collected through the methods of desk review and interviews. Accordingly, the Sinhala and English versions of the trilogy were referred, and a comparative analysis was conducted in order to manifest the results aptly. As per the scrutinised data, borrowings, calques, hybrid compounds, equivalents, substitution, neologism, interpretation, combined methods, and deletion are the strategies used in the translation to depict culture-specific words. However, there are several limitations in the way they are used: loss of connotations, unfamiliarity, lost meaning, and meaning change, that harm the cultural identity of the source culture presented in the sourcebook. Finally, the study suggests some recommendations to overcome such limitations and cultural untranslatability.

AN INVESTIGATION OF FACTORS AFFECTING THE BALANCE OF TRADE IN SRI LANKA
Get PDFThis study investigates the determinants affecting Sri Lanka's trade balance (TB) using time series data from 1990 to 2020. It explores key macroeconomic variables, including inflation (INF), foreign direct investment (FDI), gross domestic product (GDP), exchange rate (ER), tariffs (TFF), and broad money (BM), employing techniques such as the ADF unit root test, ARDL approach, CUSUM plot test, and long-run test. The results reveal that, in the long run, tariffs positively influence the trade balance, while inflation, GDP, and the exchange rate have a negative impact. In the short run, only the exchange rate shows a significant effect. These findings highlight the crucial role of macroeconomic factors in shaping Sri Lanka’s trade balance, offering valuable insights for policymakers to develop strategies that could improve the country's economic stability
Development of Banana Flour Incorporated Biscuit and Evaluation of its Physicochemical Properties
Get PDFThe Postharvest loss of Embul banana (Musa spp.) is very high due to its surplus production in Sri Lanka. This work aims towards the development of nutritionally rich biscuits by partial replacement of wheat flour with banana flour and candied citrus peel (Citrus aurantifolia). During the preliminary studies, the appropriate proportion of wheat flour, banana flour, and citrus peel was selected through a sensory evaluation using 9-point hedonic scale by 20 untrained panelists. The final product was prepared using the selected composition of banana and wheat flour 50:50 and 10% citrus peel. Significant differences were observed in all the sensory properties (p<0.05) except appearance (p>0.05) during the storage period. Ascorbic acid content was significantly reduced (p=0.000) with the storage period. The product was microbiologically safe for consumption for up to 2 months period. This study investigated the potential of the development of Embul banana-based biscuits with improved functional and nutritional properties.
