The study investigated the socio-economic and environmental impact of hydropower projects in Rwanda with a case study of Rubagabaga hydropower Ltd operating from Nyabihu District. It examines the impact of a socio-economic and environmental hydropower plant in Rwanda, identifies the challenge hydropower plants face in Rwanda, and finally investigates the relationship between hydro powers and their socio-economic impact in Rwanda? In this research, the quantitative research design is based on statistical data of the research that was used with quantitative and qualitative methods. Questionnaires were used to collect data. The target population of this study was made up of 252 participants including 154 respondents all from ten different villages surrounding the Rubagabaga plant in Nyabihu District. Data were analyzed using descriptive and correlation analysis and tables that were interpreted to confirm or deny the relevance of the main and specific objectives. Based on results from table no.16 demonstrates that the beta= 0.397 with the t value of 2.333 and the p-value of 0. 021. Since the p-value is less than 0.05, the researcher rejected the null hypothesis and considered it an alternate. There is a strong positive relationship between environmental assessment of hydropower plant projects and socio-environmental sustenance and development. In a nutshell, the researcher has rejected the null hypothesis and considered its alternate. Community structure and dynamics have a positive influence on socio-environmental sustenance and development. Table no.16 shows that beta= 0.341 with the t value of 2.668 as the p-value was 0.009. Since the p-value is less than 0.05. Therefore, the researcher rejected the null hypothesis and considered it an alternate. According to table no.21, the changes in community structure and dynamics of the hydropower plant project cause the increase of 0.341 (34.1%) of the socio-environment sustenance and development. The ratio of beta modal results for the t value expressed t=2.66 hence the probability value is significant on socio-environment sustenance and development noting that sig. =0.009. Carefully, the researcher has rejected the null hypothesis and considered its alternate. With this in mind, community structure and dynamics has a positive influence on socio-environmental sustenance and development. Table no.16 has shown beta= 0.478 with the t value of 4.543 as the p-value was 0.000 which is less than 0.05. According to the findings, the changes in government policies, stability, and support of hydropower plant project causes the increase of 0.478 (47.80%) of the socio-environment sustenance and development. The ratio of beta modal results for the t value expressed t= 4.54 hence the probability value is significant on socio-environment sustenance and development noting that sig. =0.000.

Background: Knowledge loss causes challenges for organisations that wish to remain competitive. These organisations must identify the risks that could lead to knowledge loss and become aware of issues that affect knowledge retention.Objectives: The objective of this research was to identify tacit knowledge retention barriers that could cause knowledge loss in an organisation. The paper presents a framework for the assessment of the impact of these barriers and discusses the research findings in order to critique that framework.Method: A quantitative strategy was used to interpret the findings. The target population is information technology (IT) professionals in a government organisation. Interviews were conducted in order to produce a more context-sensitive interpretation of the findings. A quantitative research approach was used to ensure the findings would precisely reflect the target population.Results: The majority of respondents confirmed that career development requires professional development, training prospects and improves the employability of employees. The agreed result was that respondents seek autonomy, that is, the ability to make decisions. Job stress and burnout are experienced because of problems with in filling posts, and the competition between the private and public sectors for experienced IT employees.Conclusion: Certain determinants were found that affect barriers in knowledge management: organisational commitment, job satisfaction, job characteristics and talent management. These need to be measured to prevent barriers from occurring. Implications are drawn from the study; these provide a focus for further research to bridge some gaps in information technology that currently limit the widespread use of knowledge management.

Abstract The interdependent fundamental systems, water and energy, face abundant challenges, one of which is climate change, which is expected to aggravate water and energy securities. The hydropower industry's benefits have led to its development and growth around the world. Nonetheless, climate change is expected to disturb the future performance of hydropower plants. This study looks at the Seimareh Hydropower Plant to assess the potential vulnerability of hydropower plants to climate change. Results indicate that climate change will affect the area's hydrological variables and suggest an increase in temperatures and decrease in precipitation during a 30-year future period (2040–2069). It is predicted that Seimareh Dam's inflow will decrease by between 5.2% and 13.4% in the same period. These hydrological changes will affect the Seimareh plant's performance: current predictions are that the total energy produced will decrease by between 8.4% and 16.3%. This research indicates the necessity of considering climate change impacts in designing and maintaining hydraulic structures to reach their optimal performance.

There are numerous dietary recommendations during pregnancy. However, there are limited recommendations during the lactation period, a nutritionally vulnerable period for women. The Mediterranean Diet and adherence to the Healthy Food Pyramid (HFP) is considered as the standard for healthy eating. In this study, we investigated the differences in adherence to the HFP in pregnant, lactating, and non-pregnant/non-lactating (NPNL) women concerning sociodemographic factors. A sociodemographic and nutritional and lifestyle questionnaire (AP-Q) were used to assess adherence to the HFP, including lifestyle. The AP-Q score ranges from 0 to 10 meaning the higher the score, the greater the adherence to the HFP. Lactating women had the lowest AP-Q score (6.13 [5.31; 6.82]) compared to the pregnant (6.39 [5.56; 7.05]) and NPNL women (6.27 [5.43; 6.88]), while pregnant women had the highest scores. Maternal age was positively correlated with AP-Q score in pregnant (rho = 0.22; p-Value < 0.001) and lactating women (rho = 0.18; p-Value < 0.001), but not in NPNL women. Educational level and monthly income had a positive influence on the degree of adherence to the HFP. In conclusion, breastfeeding mothers of young age and low socioeconomic and educational level would be the target population to carry out nutritional interventions that improve their adherence to the HFP. The knowledge gained from this study can help to design recommendation guidelines and nutritional educational interventions for a given population.

The effective performance of any Construction Project to a large extent depends on how deliberate, well thought, planned and managed works programming is developed and implemented. Effective works programming helps those doing the project to make sure that it is done within scope, time and cost. This study adopted a case study design and simple random sampling technique to identify 102 respondents from a target population of 132 respondents. Descriptive and inferential statistical techniques were employed. The findings were; there was a strong correlation between the predictor variable on the dependent variable. The ANOVA analysis indicated a P-value of 0.000. Therefore, the prevalence of working program applicability, adherence to effective work programming and knowledge of work programming techniques had a significant impact on the effectiveness of construction projects delivery. The study rejected the null hypothesis that the prevalence of working program applicability did not affect the delivery of construction management projects and knowledge of work programming did not affect the delivery of construction management projects in Kiambu County. However, the study failed to reject the null hypothesis that adherence to work programming did not affect the delivery of construction management projects in Kiambu County. Therefore, the study concluded that the prevalence of working program applicability significantly affected the delivery of construction management projects in Kiambu County and knowledge of work programming significantly affected the delivery of construction management projects in Kiambu County. The primary focus of this study was injecting solutions through integrating technology to enhance efficiency in real-time monitoring and evaluation. With the model of planning, control, reporting and proactive remedial action for the performance of construction projects

The environmentally friendly concept in terms of water quality represents a condition for developing hydropower plants all around the world. Since 2017, hydropower has represented more than 70% of all renewable energy production and it is essential for the integration of the other renewable sources of energy and for regulation of the grid. To maintain the “green” label concerning the dissolved oxygen level (6 mg DO/L), the energy suppliers should respond to environmental concerns about the operation of hydropower plants. In the context of sustainable development, the ecological degradation of rivers is unacceptable due to the implementation of a hydropower plant on the watercourse. For deep reservoirs or tropical regions, the oxygen level in the water downstream of the hydropower plants may be low and affect the aquatic life for many kilometers downstream. This paper presents a new aeration system for discharged water from hydropower plants that provides water aeration with minimum energy consumption. The influence of the aeration process on the turbine operation and efficiency is analyzed. Experimental measurements are carried out on site on a small Francis turbine. The influence of the aeration process on the turbine mechanical performances (vibration level and relative displacement) and hydraulic performances (turbine efficiency, power output, and pressure fluctuation) is analyzed. The results showed that the impact of the aeration device implementation and operation over the energetic characteristics of the turbine is in the efficiency measurements accuracy range. The aeration through this device did not influence the turbine operation (vibration, level, or pressure fluctuations).

The purpose of this paper is to investigate the impact of General Education in enhancing the Self-efficacy of Cost and Management Accounting (CMA) students to assess whether Self-efficacy, is having any positive influence on the students’ academic performance. The research design for this paper was descriptive, longitudinal and a mixed-method approach. The nature of the quasi-experimental approach that was used in the current paper is a non-equivalent pre-test and post-test control group design. The target population was CMA students. A census survey was conducted. Findings, which were analysed with the aid of descriptive statistics, indicate a significant correlation in the post-test (Self-efficacy) scores of the group that undertook the General Education Modules and not the group that did not undertake the General Education Modules. This paper recommends the implementation of General Education skills into the curriculum and a model to measure Self-efficacy of students. Moreover, these skills appear to be very poor amongst current learners and respondents believed that Self-efficacy could have a positive effect on the academic performance of learners.
