This study used 88 time series data to fit the seasonal Autoregressive Integrated Moving Average model (SARIMA). ARIMA (3,1,1) (0,1,0)[4] model was built and used for forecasting. The results show that there will be an increasing membership enrolment overtime over the years and no signs of decreasing. Thus, the government, apart from continuing  subsidizing the cost of accessing health insurance services,  should also improve the National Health Insurance (NHI) coverage to accommodate the increased enrolment and discourage dropouts. In turn, this will help to achieve the Universal Health Coverage (UHC) ultimate aim of ensuring equitable access to essential and manageable healthcare services, regardless of individuals’ financial situations, their location, and personality.","PeriodicalId":508465,"journal":{"name":"SCIENCE MUNDI","volume":"76 26","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141818862","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 this regard, this study examined the effect of crude oil price fluctuations on Tanzania’s economic growth from 1989 to 2022. Empirically this study utilized time-series data extracted from World Bank in particular, GDP per capital from World Development Indicators (WDI) as proxy of economic growth and Statistical Review of World Energy for Crude Oil prices. In this study, Renaissance growth theory, Autoregressive distributed lag model (ARDL), Dickey and Fuller tests, The Johansen test for cointegration, Breusch- Godfrey test for Serial correlation LM, Breusch-Pagan heteroscedasticity test, Jarque-Bera normality test, Error Correction Model (ECM), Granger Causality test, CUSUM and CUSUMSQ curves tests were used to analyse the data. This study revealed that crude oil price changes have positive and significant impact on Tanzania’s economic growth. A dollar increase in crude oil prices brings about 0.232791unit increase Tanzania’s economic upturn in the short run. The ARDL results also shows that error correction model (ECM) of -0.1000 (p= 0.0025) is significant with its value, suggesting a moderate speed of convergence to equilibrium after shock. Thus, this study recommends to policy maker and the government to ensure that they use fiscal policies that will reduce the adverse impact of the world crude oil prices hikes, finding other sources of energy and promoting research and development to explore and harness the oil fossils to produce oil and reduce oil importations and increase oil exportations to further increase economic growth.","PeriodicalId":508465,"journal":{"name":"SCIENCE MUNDI","volume":"124 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141682027","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 shed light on this, therefore this study investigated the impact of population dynamics on Human Immunodeficiency Virus (HIV) prevalence using a two-stage residual inclusion (2SRI) regression model to address potential endogeneity. The Hausman Test confirmed endogeneity among the variables, justifying the 2SRI model's application. Key findings indicate that population growth rate, fertility rate, and the population aged 15-64 significantly and positively affect Human Immunodeficiency Virus (HIV) prevalence. The instrumental variable, Children ages 0 to 14 young individual infected by HIV, 15 to 24 newly affected by Human Immunodeficiency Virus (HIV), and Children 0 to 14 living with Human Immunodeficiency Virus (HIV), was validated for strength, demonstrating robustness against weak instrument issues. Results revealed that a 1% increase in population growth rate leads to a 53% increase in Human Immunodeficiency Virus (HIV) prevalence. Additionally, the Dumitrescu & Hurlin Granger non-causality test established that population growth rate Granger causes Human Immunodeficiency Virus (HIV) prevalence.

The following were specific objectives of the study: to analyze the effect of contract planning on performance of Rwanda Development Board, find out the effect of contract negotiation on performance of Rwanda Development Board, assess the effect of contract implementation on performance of Rwanda Development Board and assess the effect of contract monitoring on performance of Rwanda Development Board. To achieve these objectives, literature was reviewed on the subject matter, and then data was collected from 156 employees of RDB and they were chosen by using census sampling technique. Questionnaire, observation, interview guide and documentation were used as tools of data collection. Data was analyzed by using both quantitative data and qualitative data by presenting the findings of respondents through the mean and standard deviation. Findings indicated that there is positive link between contract management and organizational performance whereas it was found that the effect of all contract management on organizational performance will be 1.462 percent; a unit increase in the use of contract planning would lead to an increase in RDB's performance by 19.2%; a one percent increase in the use of contract implementation would lead to an increase in RDB's performance by 3.8%; a one percent increase in the use of contract monitoring would lead to an increase in RDB's performance by 11.5%; and lastly, a one percent increase in the use of contract monitoring would lead to a 35% increase in RDB’s performance. Overall, contract monitoring had the greatest effect on RDB’s performance, followed by contract implementation, while contract planning took third place, and lastly, contract negotiation. At a 5% level of significance and a 95% level of confidence, contract planning varies at a 0.010 level of significance; contract negotiation had a 0.048 level of significance; contract implementation had a 0.031 level of significance; and contract monitoring had a 0.029 level of significance. All the variables were significant (p<0.05).

This study investigated the impact of beneficiary participation on the performance of an HIV peer education program implemented by the Rwanda Network of People Living with HIV (RRP+) in Gicumbi District from 2017 to 2020. Researchers examined three specific areas: project planning, implementation, and monitoring. Stakeholder and Engagement Theory alongside Participation Theory were reviewed. The study adopted a descriptive research design with qualitative and quantitative approaches. The total study population for this research was be 3,938 that included Recipients of Care (RoC) and stakeholders directly involved in the HIV peer education project implemented by the Rwanda Network of People Living with HIV (RRP+) in Gicumbi District, Rwanda, from 2017 to 2020. A mixed sampling approach was employed to select participants for this research. This approach involves a combination of probability and non-probability sampling methods. Therefore, the sample size calculated using the Yamane formula was 387 Recipients of Care (RoC) and stakeholders. Both descriptive and inferential statistics were used to analyse the data. Findings indicated significant beneficiary involvement in strategic planning and annual plans, with mean scores of 3.78 and 3.50, respectively, on a 1-4 scale. Moderate familiarity with the Work Breakdown Structure (WBS) (average 3.22) was observed. Statistical analysis confirmed a significant positive impact on Project Performance (p < 0.05). Beneficiaries reported satisfactory healthcare and psychosocial support (mean score 0.99) and moderate satisfaction with supportive supervision (mean score 1.62). Capacity-building (average 1.02) showed room for improvement, yet still had a significant positive influence on Project Performance (p < 0.05). Limited involvement in monitoring (mean score 1.04) was observed, with high satisfaction in feedback meetings (mean score 4.15).
