Using Videoconferencing to Augment Blended Learning for Synchronous and Asynchronous Teaching in Educational Emergencies Alice, Njuguna The unprecedented onset of COVID-19 and the emergency closure of institutions of Higher learning heralded a new way of completing the curriculum and taking the students through the academic calendar. Previous definitions of emergency education had tried to allude to war, civil strife, floods, drought and even some instances of HIV AIDS or children living on the streets. The COVID-19 gave a new definition to emergencies, as it led to forced containment and requirement for social distancing on a global level. Prior to the pandemic, Learning Management Systems (LMS) had been around in what would be termed as E-Learning, computer-based education and other computer related terms, Most of the LMS would support both synchronous and asynchronous education. However, face to face learning was still the preferred mode of teaching, and the online component was considered complementary and supplementary. COVID-19 led to Emergency Remote Teaching, and this brought about a change in approach and rethinking of the technologies available for remote teaching. Many Universities had to find a way of providing a supplementary way of providing live and synchronous classes. Previous applications such a ZOOM, Google Meet and Microsoft Teams found their use in the educational setup, with many Universities subscribing to these tools as well as those that are embedded in LMS, such as the BigBlueButton as used to together with MOODLE as a plugin. The aim of this study was to establish how Videoconferencing tools are used to provide synchronous and asynchronous education. The objectives were to establish how Videoconferencing tools are used to aid in teaching and learning, how these tools are used to mirror a face to face class, as well as the challenges faced in integrating these tools in the classroom. This study used a quantitative and qualitative approach where a web-based questionnaire with both open and closed questions were posted to an E-learning special interest groups consisting of faculty in both private and public institutions in Kenya and some students taught by these faculty, and followed by in-depth interviews via Videoconferencing The study established that many institutions turned to stand alone and open source videoconferencing tools to teach both synchronously and asynchronously in a blended mode. The biggest challenge was in the IT element due to non-availability of stable internet connectivity and the fact that neither the students nor the faculty had clear training on the tools available within the videoconferencing applications, and there was no formal method of integrating the same to teaching. The study recommends a policy framework on the integration of such tools in the teaching.

Baseline Survey on Software and Tools for Odel and Digital Learning during and Post Covid 19 in Selected Universities in Kenya Samwel, Mungai Mbuguah; Alice, Njuguna; John, Makokha; Catherine, Njoki; Anselmo, Peters Ikoha; Alice, Nambiro; Ben, Nyongesa; Cyrus, Barasa One the mitigating measures adopted against the spread of COVID-19 was closure of business, suspension of face to face learning in institution of learning in Kenya and cancellation of international flights worldwide. There was also enforced locked down within highly infected areas. To survive educational institutions adopted mainly online/digital learning. In this paper we provide findings on a survey conducted in selected eleven universities in Kenya on the status of the soft wares and tools that facilitate online/ digital learning. The finding indicate that even though the universities had adopted blended learning the soft wares and tools are still a challenge. The Paper recommends the need of the institutions to enhance the acquisitions of tools and soft wares for an enhanced digital learning and inclusion.

Unsteady MHD Flow of a Fluid past a Rotating Semi-infinite Plate with Inclined Magnetic Field Samuel, Macharia Karimi This paper investigates unsteady two-dimensional MHD flow past a rotating semi-infinite plate with an inclined magnetic field with viscous dissipation, Ohmic and Joule heating. The fluid is assumed to be electrically conducting. The governing non-linear partial differential equations for mass, momentum, energy, concentration and magnetic field are transformed into a couple system by using appropriate dimensionless parameters and quantities. The coupled systems are then coded in MATLAB and solved simultaneously using the Gauss Seidel iteration technique. Various flow parameters and quantities are varied and their effects on velocity, temperature, and concentration profiles are investigated and discussed. It is observed that the transient velocity profiles increase with the increment of the Prandtl number, Grashof number, Hall parameter and Eckert number, while they decrease with the increase of the angle of inclination of the magnetic field and Hartman number. The temperature profiles rise with increasing the Grashof number, Hall parameter, Eckert number and Joule heating parameter while they decrease with increasing the Prandtl number, angle of inclination of magnetic field and Hartman number. The concentration profiles decline with increasing the Schmidt number and, the magnetic induction profiles decrease with increasing the magnetic Reynolds number and angle of inclination. The concept behind MHD is that the magnetic field induces current in a moving conductive fluid, which in turn generates a force on the fluid. This research is of great interest in applications such as MHD boats, pumps and magnetic material processing.

Evaluating the Effectiveness of Kenya’s National Green Finance Strategy in Achieving Sustainable Economy and Climate Goals. Wicliffe, Otieno Anyango Kenya acknowledges the imperative of integrating green finance into its financial systems to combat climate change and promote environmental sustainability. Despite its commitment to a comprehensive green finance strategy, there remains a significant gap in understanding its actual impact. This study assesses Kenya’s National Green Finance Strategy, focusing on its effectiveness in achieving climate goals by mobilizing green investments and influencing financial institutions to adopt sustainable practices. The primary variables studied include the alignment of financial policy and institutions with green finance principles and the mobilization of green investments. Grounded in Stakeholder Theory and the Theory of Sustainable Finance, the study employs a mixed-methods approach, integrating policy analysis, stakeholder interviews, and case studies. Initial findings highlight progress in fostering green finance while exposing deficiencies in regulatory frameworks, financial inclusion, and public awareness. Although the strategy has partially mobilized green investments, financial institutions have not fully embraced green finance principles. Regression analysis demonstrated high explanatory power (R² = 0.9992, Adjusted R² = 0.9962, F-statistic = 330.8, p = 0.04121), confirming the significant role of financial and institutional resources in mobilizing green investments. Granger causality tests revealed potential temporal dependencies between investment inflows and greenhouse gas (GHG) emissions, showing significant self-causality within GHG emissions data. However, GDP and renewable energy share showed no significant effects. The study concludes that addressing gaps in regulatory frameworks, enhancing financial inclusion, and raising public awareness are critical. Implementing these recommendations could fortify Kenya’s green finance mechanisms, contribute significantly to global climate goals, and provide a model for other developing nations striving to align their financial systems with sustainability principles. By tackling these challenges, Kenya can unlock its full potential in mobilizing green investments, fostering institutional change, and driving the transition to a low-carbon economy. The study further establishes that the development of stakeholder engagement frameworks is necessary, actively engaging local governments, the community, and private investors in the design and delivery of green finance projects and ensuring participatory processes underpin the projects, a precept of Stakeholder Theory.
