From Vision to Impact: How Africa Can Deliver on its AI Strategy
(UbuntuNet Alliance for Research and Education Networking, 2025-09) Ogot, Madara
The African Union (AU) Artificial Intelligence (AI) Strategy (2024) aims to catalyse inclusive AI-enabled growth and safeguard sovereignty, individual and organisational rights (African Union, 2024). The Hierarchy of Engagement with AI (HE-AI) model (Ogot, 2025) offers a practical framework for its implementation. The model frames individual and organisational engagement with AI as a progression along eight maturity levels. It integrates technical capability, governance, ethics, workforce, and ecosystem collaboration into a manageable and measurable stage-gated journey. Executing the Strategy's goals requires a staged evidence-based pathway that the HE-EI model provides. The model's sequenced logic, aligned with the Strategy's phased plan, will support its implementation.
Biological Neural Calculator Using Plant-Based Electromagnetic Responses
(Publisher, 2025-09-10) Barack Ndenga
I propose a novel concept: a Biological Neural Calculator based on plant-derived electromagnetic fields. This work explores the possibility of harnessing bioelectromagnetic signals from plants as computational units, forming a new paradigm of information processing. By modeling plant electrophysiological activity as nodes within an information gradient network, I demonstrate how computation can be achieved beyond silicon-based systems. This article provides the theoretical framework, mathematical demonstrations, system architecture, operational design, and practical steps to build and use such a device.
The originality of this approach lies in the integration of living systems into computational theory. Unlike traditional hardware, which is rigid and energy intensive, plants operate as dynamic, adaptive entities responding to multiple external stimuli. Their natural electromagnetic emissions can be captured, quantified, and transformed into logical operations. Thus, the biological neural calculator offers a sustainable and self-adaptive alternative to conventional computing.
This work also situates the concept within broader scientific contexts, linking plant electrophysiology to computational neuroscience, bio-inspired artificial intelligence, and green technology. By providing a practical blueprint and mathematical foundation, the article bridges abstract theory with experimental feasibility. The proposal therefore represents both a conceptual breakthrough and a call for interdisciplinary exploration.
EFFECT OF PUBLIC FINANCIAL MANAGEMENT REFORM ON FINANCIAL OPERATIONS: THE CASE OF MINISTRY OF FINANCE IN PUNTLAND STATE OF SOMALIA.
(2022-08-13) Moulid Abdirahman Ali
The PFMRs seek to address gaps identified in the devolved systems of government and public organizations to remedy inadequate strategy orientation and lapsed strategy as well as to build on institutional transformation. The purpose of this study to investigate the effects of public financial management reforms on financial operations in the Ministry of Finance of Puntland State.. To achieve this purpose the researcher was formulated research objectives. This study adopted a descriptive survey design and multiple regression analysis where the population comprised of 120 respondents at the Ministry of finance headquarter. The researcher used primary and secondary sources to collect the data through the use of a questionnaire, which comprised of close-ended questions. The sample of this study was 92 who had taken from the target population for the survey.The study was guided by three objectives; To examine the effect of Political Commitment on financial operation, To examine the effect technical capacity of staff on financial operation and To examine the effect Donor support on financial operation in the ministry of finance in Puntland state, Somalia.The study found that Poor political commitment and lack of sufficient technical capacity were the most prevalent hindrances in the implementation of public financial management reforms. The study concludes that the role of donors support had significant effect on PFM reform. Despite the fact that donors were not fully funded the PFM reforms to implement successfully. The study recommended that the Puntland government have to create strong political commitment, should improve and adopt appropriate technical capacity enhancement to ensure the quality, reliability to achieve the implementation of PFM reform. Puntland State should allocate budget and special departments for the implementation of PFM reform to ensure the sustainability of the program.

Abstract
The PFMRs seek to address gaps identified in the devolved systems of government and public organizations to remedy inadequate strategy orientation and lapsed strategy as well as to build on institutional transformation. The purpose of this study to investigate the effects of public financial management reforms on financial operations in the Ministry of Finance of Puntland State.. To achieve this purpose the researcher was formulated research objectives. This study adopted a descriptive survey design and multiple regression analysis where the population comprised of 120 respondents at the Ministry of finance headquarter. The researcher used primary and secondary sources to collect the data through the use of a questionnaire, which comprised of close-ended questions. The sample of this study was 92 who had taken from the target population for the survey.The study was guided by three objectives; To examine the effect of Political Commitment on financial operation, To examine the effect technical capacity of staff on financial operation and To examine the effect Donor support on financial operation in the ministry of finance in Puntland state, Somalia.The study found that Poor political commitment and lack of sufficient technical capacity were the most prevalent hindrances in the implementation of public financial management reforms. The study concludes that the role of donors support had significant effect on PFM reform. Despite the fact that donors were not fully funded the PFM reforms to implement successfully.

Design of multi-target hybrid molecules for synergistic therapy of malaria and human African trypanosomiasis
(Publisher, 2025-09-08) Barack Ndenga
The increasing resistance of Plasmodium spp. and Trypanosoma brucei to conventional antimalarial and trypanocidal drugs poses a major challenge for global health. In response, this study introduces a computationally-driven hybrid multi-target drug design strategy, using AutoEvoChem V2.0, a platform developed by the author.
I propose a series of unprecedented candidate molecules derived from drug repurposing and rational hybrid design, including derivatives of Rufinamide, Disulfiram, Clofazimine, Sulforaphane, and Benserazide. These hybrids combine molecular fusion, controlled pro-oxidant motifs, peptide targeting, and nanoparticle encapsulation, aiming to enhance efficacy and selectivity against malaria and human African trypanosomiasis (HAT).
Computational docking and ADMET predictions indicate that these hybrids possess strong multi-target activity, synergistic mechanisms, and favorable pharmacokinetic properties, potentially overcoming limitations of current monotherapies. This study establishes a proof-of-concept framework for designing next-generation multi-mode anti-parasitic therapies and highlights the potential of computational innovation in accelerating drug discovery for neglected diseases.
