Using qualitative descriptive phenomenology, the study was conducted among 14 purposefully chosen Indigenous young mothers aged 14-17 years old and caring for at least one child who is two years of age. There were seven participants for the focus group discussion and seven for the in-depth interview. The descriptive phenomenological method developed by Colaizzi was used in the research study to analyze data. The study's findings showed that the challenges experienced by the participants were used to process the data. The three main themes of the study are as follows: The Winding River of Motherhood, Prayer as a Universal Solvent, and Navigating Life’s Waters. The means of coping with the challenges the participants experienced were Faith’s Resilient Beacon, and Pillars of Unwavering Support. Finally, the insights they shared with their fellow Indigenous mothers and society in general were the themes: The Art of Making Wise Choices, The Scholar’s Beacon, and Echoes of the Looking Glass. It entails that the families, government, and other concerned agencies aggressively promote and offer educational opportunities, livelihood programs, and healthcare services for young Indigenous mothers as a powerful advocacy to positively impact their life paths. ","PeriodicalId":418878,"journal":{"name":"European Journal of Theoretical and Applied Sciences","volume":"90 1-3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140526391","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}

To answer the research gap, we developed the concept of digital literacy strategic advantage rooted in Reource advantage Theory of Competition (Hunt&Morgan,1995). We used a sample size of 125 MSMEs spread across three city districts in Maluku province using a non-probability sampling technique with a non-proposive sampling approach. To test the hypothesis, we used structural model analysis with the help of the AMOS SEM version 26 program. The results explained that the three hypotheses we proposed had a positive and significant effect on the business performance of MSMEs in Maluku province. Our theoretical implications and managerial implications are explained to be taken into consideration for theory development and MSME development. ","PeriodicalId":418878,"journal":{"name":"European Journal of Theoretical and Applied Sciences","volume":"4 4","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140525206","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}

The water, the sky, construction materials and the earth's crust all release natural background radiation that contaminates the environment around us. Additionally, people are exposed to background radiation that comes from internal, cosmic, and terrestrial sources, although, the altitude determines the amount of cosmic radiation exposure, and high altitudes result in large radiation doses. Monitoring the amounts of radiation to which humans are exposed, either directly or indirectly, requires an understanding of the natural background radiation in the environment. The current study attempted to create a baseline of outdoor background radiation in FCT for exposure rate, absorbed dose rate, annual effective dose equivalent, and excess life cancer risk. The study used a very sensitive survey meter to measure the BIR. The average BIR value found in the research areas is marginally below the 0.013mRh-1 global BIR level, indicating an almost high BIR level for the FCT while the absorbed dose rates of 105.85nGy/hr was greater than the 59nGy/hr global population weighted average gamma dose rates estimate. The obtained annual effective dosage equivalent value is greater than the global average normal annual effective dosage level for outdoor environments, and the excess lifetime cancer risk values were higher than the 0.29×10-3 allowable level as reported by UNSCEAR & ICRP. Therefore, the general people and those who live in environmentally sensitive areas may experience immediate health effects from contamination and radiation levels at the current rates. ","PeriodicalId":418878,"journal":{"name":"European Journal of Theoretical and Applied Sciences","volume":"124 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140525627","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}

Emerging water resource management challenges have driven governments to reform governance policies. This includes the introduction of formal institutions of water management. Additionally, the Tanzanian government adopted Integrated Water Resources Management (IWRM) frameworks. However, evidence indicates that establishing formal institutions (which replaced the informal ones) has achieved little in improving water supply and ensuring sustainable water management. This study asks what is still needed to achieve sustainable water management in Tanzania. Using a systematic literature review, the study examined the experience of water resources management in Tanzania, particularly the formal institutions. The study found that formal institutions have been unable to ensure sustainable water resources management; they have weakened the informal institutions and attracted water conflicts. The study calls for considering and integrating the informal institutions (that have been serving communities for generations) in water resources management initiatives. ","PeriodicalId":418878,"journal":{"name":"European Journal of Theoretical and Applied Sciences","volume":"96 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140515791","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}

Among others are particulate matters (PM) from vehicle exhaust that produce a complex mixture of pollutants, principally comprised of polycyclic aromatic hydrocarbon (PAH). This systemic review aimed to explore the PAH exposure and the associated health impacts among street food vendors. PubMed, Science Direct, and Google scholar were the platforms used to access published articles, journals, manuscripts, reports, and theses. The keywords included were “PAH”, “vehicle emission”, ‘environmental pollution”, “street food vendors”, “1-OHP”, “cooking oil fumes”, “street business” and “health hazards”. A total of 10 articles were selected that included studies emphasizing PAH exposure and overall health impact towards various population of the study. The results show that PAHs are highly carcinogenic and are also considered teratogenic and mutagenic. Vehicle emission can be classified as one of the essential contributors of PAH among street food vendors. In addition, incomplete combustion of organic materials such as coal and wood as well as generation of cooking oil fumes (COF) put the street food vendors at increased risk. Exposure to PAH can result in the increment of oxidative stress level which can further cause development degenerative and non-degenerative diseases, including cardiovascular and pulmonary diseases, diabetes, and Alzheimer's disease. Hence, it is crucial that the extent of PAHs exposure is assessed, so that preventive measures can be implemented. ","PeriodicalId":418878,"journal":{"name":"European Journal of Theoretical and Applied Sciences","volume":"51 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140520317","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}

The association among these variables to jointly predict academic achievement has been vague and nebulous in the field of educational psychology. The study aimed to explore the students’ social goal orientation, academic engagement, and creativity as predictors of academic achievement in mathematics in Anambra State. Four research questions and three null hypotheses were formulated for the study. The study adopted a predictive correlational design. The population comprised of 21,204 SS II students from which a sample of 1560 was drawn using probability sampling procedure. Standardized research instruments such as; Social Goal Orientation Questionnaire (SGOQ), Students’ Academic Engagement Questionnaire (SAEQ) and Epstein Creativity Competencies Inventory (ECCI) developed by Epstein were used for data collection. Students’ mathematics achievement scores from the state wide promotion examination were used to represent mathematics achievement. Cronbach’s alpha was used to determine the reliability of the items in the instruments. A reliability indices were found to be .88, .82, and .92 for SGOQ, SAEQ and ECCI respectively. These scores made the instruments fit for the study. The standard multiple regression was used to analyze the collected data. The standard multiple regression was used to analyze the collected data. The research question 1 was answered using multiple regression. The research question 2 was answered using unstandardized β. The research question 3 was answered using adjusted R2. The research question 4 was answered using standardized β. The null hypothesis 1 was tested using F-test for regression model. The null hypothesis 2 was tested using t-test for adjusted R2. The null hypothesis 3 was tested using t-test for β at .05 level of significance. Findings showed that students social orientation, academic engagement and creativity scores yielded an adjusted R square of .007. This implies that predictors accounted for about 0.7% of the variance scores in academic achievement. Also, the analysis of variance indicated that the regression equation was significant in predicting academic achievement in mathematics. This implies that at least one of the independent variables significantly predicted academic achievement in mathematics. Based on these findings, it was recommended that students should consider social goal orientation, academic engagement and creativity as adaptive motivational variables that have jointly predict academic achievement. ","PeriodicalId":418878,"journal":{"name":"European Journal of Theoretical and Applied Sciences","volume":"11 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140516335","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}
