    Household food waste is driven by consumer habits and behaviour, varying with demographic, social, and economic factors. This study aims to determine whether household food waste is a luxury good and identify how demographic and socioeconomic factors affect household food waste. A Quadratic Almost Ideal Demand System (QUAIDS) model was used, augmented with demographic, socioeconomic, and expenditure controls. Data from 195 respondents via an online survey in the Kurunegala district (October 2022) covered food habits and waste. Food categories included rice, cereals, pulses, fruits, vegetables, meat, fish, dairy, eggs, and miscellaneous foods. The value of Household food waste was estimated using a proxy value derived from multiplying waste amounts by monthly grocery expenditures. The demand system estimation showed that all food waste categories were normal goods. Rice, cereals, pulses, fruits, vegetables, and miscellaneous foods were necessity goods, while meat, fish, dairy, and eggs were luxury goods. Expenditure share on household food waste varies with residence area and income level, and most households practice waste management and have positive attitudes toward minimizing waste

    Quality assessment of degraded palmprints using enhancement filters

    Image enhancement in the pre-processing stage of biometric systems is a crucial task in image analysis. Image degradation significantly impacts the biometric system’s performance, which occurs during biometric image capturing, and demands an appropriate enhancement technique. Generally, biometric images are mixed with full of noise and deformation due to the image capturing process, pressure with sensor surface, and photometric transformations. Therefore, these systems highly demand pure discriminative features for identification, and the system’s performance heavily depends on such quality features. Hence, enhancement techniques are typically applied in captured images before go into the feature extraction stage in any biometrics recognition pipeline. In palmprint biometrics, contact-based palmprints consist of several ridges, creases, skin wrinkles, and palm lines, leading to several spurious minutiae during feature extraction. Therefore, selecting an appropriate enhancement technique to make them smooth becomes a significant task. The feature extraction process necessitates a completely pre-processed image to locate key features, which significantly influences the identification performance. Thus, the palmprint system’s performance can be enhanced by exploiting competent enhancement filters. Palmprints have reported a lack of novelty in enhancement techniques rather than more centering on feature encoding and matching techniques. Some enhancement techniques in fingerprints were adopted for palmprints in the past. However, there is no clear evidence of their impact on image quality, and to what extent they affect the quality in specific applications. Further, frequency level filters such as the Gabor and Fourier transforms exploited in fingerprints would not be practically feasible for palmprints due to the computational cost for a larger surface area. Thus, it opens an investigation for utilising enhancement techniques in degraded palmprints in a different direction. This work delves into a preliminary investigation of the usage of existing enhancement techniques utilised for pre-processing of contact fingerprint images and biomedical images. Several enhancement filters were experimented on severely degraded palmprints, and the image quality was measured using image quality metrics. The High-boost filter comparatively performed better peak-signal-to-noise ratio, while other filters affected the image quality. The experiment is further extended to compare the identification performance of degraded palmprints in the presence and absence of enhanced images. The results reveal that the enhanced images with the filter that has the highest peak signal-to-noise ratio (High boost filter) only show an increased genuine accept rate compared to the ground truth value. The High-boost filter slightly decreases the system’s equal error rate, indicating the potential of exploiting a pre-enhancement technique on degraded prints with an appropriate filter without compromising the raw image quality. Optimised enhancement techniques could be another initiative for addressing the severity of image degradation in contact handprints. Doing so they could be successfully exploited in civilian applications like access control along with other applications. Further, utilising appropriate enhancement filters for degraded palmprints can enhance the existing palmprint system’s performance in forensics, and make it more reliable for legal outcomes

    Ginger (Zingiber officinale) belongs to the family Zingiberaceae. Chinese, Rangoon and Local are the commonly cultivated ginger types in Sri Lanka. Local ginger is rich in fiber, uses in Indigenous and Ayurveda medicinal purposes, and amount of yield is comparatively low. Chinese and Rangoon are moderately in pungency, amount of yield is comparatively high and use in beverage industry likes for production of ginger beer and for culinary purposes also. Ginger can be grown either as a mono-crop or inter-crop under coconut plantation. This research was carried out at Inter-cropping and Betel Research Station, Narammala where the area belongs to Kurunegala district is under the coconut triangle. Coconut plants are generally spaced in 26 ft x 26 ft, hence 75% of area under the coconut plants are remaining unproductively. Underutilized area is high when the age of the coconut plants is below 5 years and over 20 years. Climatic conditions in Kurunegala district is more favourable for ginger cultivation. After the three years field experiment, the highest fresh yield of rhizome per clump for Chinese ginger accessions was given by the accession of G33 (949.2 g/clump) in Low Country Intermediate Zone under coconut cultivation. The highest fresh yield of rhizome per clump for Rangoon ginger accessions was given by the accession of G28 (754.2 g/clump) in low country Intermediate zone under coconut cultivation. The G28 and G33 accessions can be used to cultivate under coconut plantation as an intercrop to increase the productivity of coconut lands

    Get PDF
    Purpose: This study examines the relationship between corporate governance (CG) and insolvency risk (IR). It is grounded in the argument that corporate governance is essential for reducing excessive risk-taking behaviors that often lead to insolvency. The research addresses the increasing financial vulnerability of Licensed Finance Companies (LFCs) in Sri Lanka and highlight the significance of board independence, gender diversity, audit committee independence, and meeting frequency as determinants of financial stability and insolvency mitigation. Design/methodology/approach: The sample comprised 25 LFCs listed on the CSE from 2019 to 2023. The insolvency risk was measured with Altman's emerging market Z-score, and a panel regression analysis was employed to evaluate the impact of CG factors. Additionally, multinomial logistic regression analysis was used to explore the impact of corporate governance on the likelihood of insolvency risk. Findings: The results reveal a statistically significant and inverse relationship between the presence of women on boards and the frequency of board meetings with insolvency risk. The inclusion of women’s representation on the board is particularly influential in achieving low insolvency risk, while active audit committee engagement further reinforces a negative impact on the probability of insolvency. This indicates that increased gender diversity and consistent board engagement are associated with a lower likelihood of insolvency. Practical implications: This research suggests that companies that prioritize gender diversity, ensure regular board meetings, and foster active audit committee engagement are more likely to enhance organizational stability and reduce excessive risk-taking behaviors. Originality value: This study contributes to the existing body of knowledge on the role of corporate governance in managing financial risk within emerging markets. It explains the mechanisms through which governance structures influence insolvency risk, offering a critical basis for future research and policy initiatives to strengthen the resilience of financial institutions within developing economies

    Get PDF
    Purpose: Some literature on feeding kitchen food waste (KFW) to domestic animals is available. However, the quantifi-cation of such consumption by those animals is limited. This study attempts to investigate how various domes-tic animals contribute to disposing of the KFW by feeding in rural and semi-urban areas of the eastern province of Sri Lanka. Method: Simple random sampling was used to select 75 households from the Sammanthurai DS division. The KFW was collected, segregated, and weighed from each of the households. The weight of KFW fed to domestic and stray animals was recorded before feeding. A semi-structured questionnaire was also used to collect the necessary data from the households selected. Results: The study found that the KFW accounted for 49 %. 25 % of the households disposed of their KFW by feeding to the domestic animals and another 3 % was consumed by stray animals. The village chickens consumed the highest KFW (59.5 %) per day. Each village chicken, cow, other birds, dog, and cat consumed 47.8 g, 695 g, 43.3 g, 128 g, and 91.7 g of KFW per day, respectively, on average. By feeding the KFW to domestic animals, the reduction in greenhouse gas emission was estimated to be 871 kg of carbon dioxide equivalent (CO2-e) per day. Conclusion: A quarter of the households fed their KFW to domestic animals they grow. The village chickens were the highest contributor to the disposal of KFW by consuming them. Feeding KFW to domestic animals reduces greenhouse gas emissions and contributes to rural food security through bioconversion

    Development of a semiochemical-based strategy for the management of coconut white flies (aleurodicus cocois)

    Get PDF
    In Sri Lanka, the coconut industry, vital for the national economy, faces a significant threat from the recently invaded pest, Coconut White-Fly (Aleurodicus cocois). The pest's resistance to traditional pesticides and the tall nature of the palm has highlighted the need for sustainable management strategies. Therefore, it is important to find an alternative to chemical pesticides with a systemic nature, which underlines the urgency of adopting sustainable management strategies. This study aims to develop and evaluate a plant semiochemical-based management strategy for the Coconut WhiteFly, employing trunk injection as a systemic alternative to chemical pesticides. The approach seeks to provide a sustainable solution, reducing pest populations without harming the ecosystem. Plant extracts from Strychnos nux-Vomica (Goda kaduru) seeds and leaves, neem, mint, and clove oil were formulated and tested for effectiveness. Four successful formulations were prepared and tested through direct spraying. Building on the mortality success, these formulations were further incorporated with systemic carrier materials like urea, NaCl, KCl, and citric acid, then evaluated through trunk injection methods. Field experiments revealed significantly (p<0.005) higher mortality percentages (68%, 95.85%, 93.27%, and 94.66%) for formulations 1 to 4 compared to the untreated control. Trunkinjected palms exhibited a reduction in the whitefly population over time, though continuous monitoring was hindered by weather conditions, emphasizing the need for repeated applications for a successful conclusion

    Get PDF
    This study aimed to identify a new feed for Catla catla post larvae. There is no suitable feed in Sri Lanka for postlarvae of Indian carp. A complete randomized design was used. Two feeds were formulated using different nutrient compositions with 32 % and 25 % of the fish meal separately. The formulated feeds were used as treatment one and treatment two. Commercial feed was used as the control. Catla catla post-larvae were stocked at a density of 300 post larvae per m2 in nine cement tanks. Growth parameters were measured every two other days. Feeds were formulated according to the nutrient requirement of Catla catla post larvae. Water quality parameters were measured daily to maintain the water quality at the proper level. T-test preformed in Mini tab 16.0. Total body weight and length were significantly different (p<0.05). The survival percentage was higher in T1. Treatment feeds were not affected by the water quality parameters. Catla catla post-larvae show a maximum increase in length, survival percentage and weight in T1. It was concluded that T1 has a good combination of fish meal for Catla catla post-larvae. This study will help in future feed formulation for post-larvae feeds in developing nations

    The study of gestalt and cognitive psychological theory influences the creation of user interfaces and user experiences

    Get PDF
    In the rapidly advancing realm of digital technology, the imperative of creating innovative and user-centric interfaces cannot be overstated. This research undertakes a comprehensive exploration of Human-Computer Interaction (HCI), with a specific focus on harnessing the insights derived from gestalt and cognitive psychological theories to redefine the art of user interface (UI) design and elevate user experiences to new heights. One of the pressing challenges in contemporary digital design lies in the unsettling uniformity that characterizes many UIs. The research methodology comprises four distinct phases. The initial phase involves the meticulous crafting of an ideal UI prototype for an e commerce platform. The second phase entails an exhaustive review and synthesis of UI design theories grounded in Gestalt and Cognitive psychology. The third phase is marked by the assimilation of these theories into the UI design process. Finally, the fourth phase involves the integration of user feedback, a critical step in validating and comparing the ideal UI prototype against the newly developed UIs infused with psychological principles. In conclusion, this research underscores the vital importance of transcending the ordinary in UI design. By harnessing the potential of Gestalt and Cognitive psychological theories, we aspire to dismantle the shackles of design uniformity, providing users with interfaces that are not just personalized but also harmonized with the intricacies of human cognition. In this pursuit, we anticipate a paradigm shift in HCI, where engagement and user-centricity reign ultimately elevating user satisfaction, productivity, and the overall quality of the digital experience
