They use nature as a means of survival and need satisfaction. Animals are part of nature and many environmentalists struggle for survival and the right to life of animals. The human world is focused solely on industrial development, human livelihoods and the instrumental value of nature. When discussing the nature and well-being of animals, it is necessary to take into account a moral consideration based on the intrinsic value of nature. This includes surviving animals for their own good, which is, protecting animals for their own betterment. Social wellbeing is defined as a better life. This research focuses primarily on how to provide a better life for animals while giving them a moral concern via the non-anthropological vision as explained by environmental ethics. Environmental ethics embraces knowledge by providing insight into thinking morally about nonhuman beings. The qualitative methodology was adopted for the research contains the philosophical and moral analysis. As a result, this implies analytical and comparative approaches to environmental ethics. Secondary data were collected as part of several articles, research and books on environmental ethics. Non- anthropocentric is a successful measure of reducing the gap between humans and animals. It is useful and useful in implementing legislation and policies that positively support the welfare of animals and the protection of all nonhuman beings. The world needs a moral philosophical consideration to protect animals and the welfare of animals .","PeriodicalId":91884,"journal":{"name":"International journal of current multidisciplinary studies","volume":"8 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82302056","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In its involvement in enhancing living conditions in the poor, developing countries might well be very different from those in the rich countries since development covers areas like social, cultural, spiritual and economic. The Samanala Wewa development project was commissioned in 1992. It has become the key factor for many socio-cultural changes in the area. The Samanala Wewa dam is located in the Uda Walawe basin, near Balangoda. The main objective of this study was confined to finding out the appropriateness of the Samanala Wewa project in paving the way for a development that would open new opportunities for the people of the area. Data for the study were collected through an interview schedule from fifty households out of 153 in three villages located near the Samanala Wewa reservoir. According to the results of this research, 86% of those who answered as “satisfied” with the project gave the reason for it as “improvement in infrastructure and access to society” brought about by the relocation to suburban areas, while 14% of those who answered “unsatisfied” raised as reasons “loss of self-sufficient economy and rural life,” showing that reaction to the change in environment caused by the relocation from rural to suburban areas varies by the resident. It is presumed that dissatisfaction or “loss of self-sufficient economy and rural life” is caused by financial difficulties such as difficulty in finding jobs and low cash income. Accordingly, this project can be identified as one which is not merely unsuccessful. However, it should be carried out with some social development projects to uplift the quality of life of the people concerned.","PeriodicalId":91884,"journal":{"name":"International journal of current multidisciplinary studies","volume":"16 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75171548","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

With the advent of the 73rd amendment in Indian constitution, the panchayat system is looked as a significant development in handling rural governance in India. In this aspect, the state of Karnataka can be considered in many ways as one of the active states in promoting decentralization. Karnataka is in the forefront when it comes to devolution of functions and financial powers to PRIs. Hence, the current study has the broad objective to undertake a situational and adopting SWOT analysis to determine the strengths, weaknesses, opportunities, and threats (SWOT) related to existing Watershed committees and Water User Co-operative Societies in Karnataka under Integrated Watershed Management Programme (IWMP) in terms of the structure, function and factors influencing in implementation of Watershed programme in the state of Karnataka, India. The findings revealed that about 90 % percent of all committees are found to exist on record (structural level), SWOT analysis clearly shown that community-led water use associations are performing better than the department led water user associations in the implementation of IWMP. While the structure and legal status of PRIs have matured over the years, it is clearly recognized that true public involvement in progress and governance through PRIs has a long way to go.KEYWORDS: Decentralisation, Participatory Development, Local Governance, Integrated Watershed Management Programme","PeriodicalId":91884,"journal":{"name":"International journal of current multidisciplinary studies","volume":"209 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-01-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90476193","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Silva","doi":"10.31357/IJMS.V6I2.4338","DOIUrl":"https://doi.org/10.31357/IJMS.V6I2.4338","url":null,"abstract":"The present study was carried out to investigate the salinity tolerance of Poecilia reticulata (guppy) occurring in Sri Jayewardenepura canal system, in order to assess its suitability to control brackishwater breeding mosquito species such as Aedes sp. Guppies were exposed to different salinity levels directly and gradually under laboratory conditions in glass tanks. To test the direct effect of salinity, 9 different salinities (ranging from 0ppt as a control to35ppt) prepared in three replicates, each stocked with 10 fish were kept for a period of 12 weeks. To test the effect of gradual increase of salinity, three tanks containing freshwater were stocked with 10 fish in each and a gradual increase of salinity (by 5ppt once in 2 weeks up to 38ppt) was done. Mortality rates, growth (total length) and the breeding of fish were recorded in both experiments at regular time intervals. When the fish were exposed to different salinities directly, fish started dying at 10 ppt (10% mortality) after the fourth day of exposure and this mortality rate was observed in 10-20ppt salinity ranges within the 12 weeks (0% mortality was recorded in control tank).  50% survival was shown at 28ppt salinity level at the end of the 12 th week. Beyond 28ppt, there was 100% mortality. Fish showed an average of 5-7 mm growth in salinity levels up to 28ppt but they were not significantly different (p=0.886). Breeding was seen in salinity levels up to 20ppt producing 7-15 fry/female and the fry also could tolerate the salinity levels they were bred into with a mortality level of 20-30% within the study period. Contrast to the above results, the fish when exposed to gradual increasing of salinity levels could survive up to 38ppt with only a 20% mortality rate. They showed a length increase between 1-5mm, in all salinity levels but they were not significantly different (p=0.330). In gradually increasing salinity levels, fish were seen breeding even at 35 ppt (7-10 fry/female) with 10-20 % mortality rate. The results show that the guppy can tolerate and survive in salinity levels up to 28ppt when they are directly introduced from the wild and they can tolerate up to a level of 38ppt salinity if the salinity levels increase gradually. They can grow under saline conditions and breed successfully and the fry can survive well in the saline environment. This makes wild caught P. reticulata (guppy) a potential candidate that can be used as a bio-control agent in the control of species such as Aedes sp-mosquito that breed in brackish water environments of Sri Lanka.

However, lesser is known about the nutritional status of the Indigenous (the Veddas) children and adolescents in Sri Lanka. The present study was conducted to assess the nutritional status of the Henanigala Vedda children and adolescents through anthropometric measurements. Stature and weight of a total of 169 children and adolescents (90 girls and 79 boys between 5-18 years of age) were measured and calculated the Body Mass Index (BMI). Subjects were categorized into three age groups, 5-8 years ( 𝑛 = 28), 9-11 years ( 𝑛 = 52) and 12–18 years ( 𝑛 = 89). According to the National Health and Nutrition Examination Survey (NHANES) subjects who were falling below the age and sex specific fifth percentile (< 5th %ile) of the BMI Cut off Points were defined as undernourished. SPSS, MS Excel and BMI metric calculator for children, were used for data analysis. In order to test the level of significance, student t-test was performed ( 𝑃 <0.05). Mean BMI of the girls of 5-8, 9-11 and 12-18 age categories were 13.22 ± 1.06, 13.39 ± 1.59 and 18.66 ± 3.42 respectively, boys were 14.78 ± 3.18, 14.76 ± 3.39 and 18.01 ± 3.38 respectively. The difference in stature was significant only between the boys and girls of the 12-18 age group. According to the BMI cut off points 67% of the girls and 60% of the boys of the 5-8 age group and 69% of the girls and 54% of the boys in the 9-11 age groups belonged to underweight category (critical). When compared with other age groups lower prevalence of underweight was found among 12-18 years age group which were 22% of girls and 35% of boys (but still at health risk). Higher prevalence of underweight among children could be due to the lower socioeconomic and educational status of their parents. In addition, sudden cultural transformations due to the resettlement which had an adverse effect on their traditional lifestyle including food practices would account for the lower nutritional status observed among the majority of the indigenous children and adolescents in Henanigala.

It can be also viewed as the systematic repetition of phonological material within a word for semantic or grammatical purposes. The aim of the present paper is to examine reduplication phenomenon in Sinhala1 in the broader spectrum of reduplication patterns and functions evidenced in many languages of the world. Data for the present study consisted of sentences with reduplication types and functions that can be distinguished in Sinhala. A sample of 60 sentences with such reduplication was used. The researcher consulted 05 adult native speakers of Sinhala for their grammaticality judgments about those sentences. The examples and example sentences used in this study are the data used for this purpose. In terms of the main findings of the study, it can be concluded that Sinhala employs reduplication in both of its spoken and written varieties in varying degrees and for various effects. In its written form, reduplication fulfills some stylistic functions and is mostly manifested in poetry, riddles, songs, anecdotes and narrations. The colloquial Sinhala uses reduplication in ordinary discourse and can be seen irrespective of the dialectal varieties. It can be observed at phonological, morphological/morpho-syntactic, and lexical levels. Sinhala manifests reduplication over a broad range of categories such as noun, verb, adjective, and adverb.
