Common Law Director Duties and Shareholder Remedies as codified into the UK Companies Act 2006
No full textThe UK Companies Act 2006 is a pioneering statutory instrument, hailed for its success in the codification of common law rules and simultaneously influencing reforms and harmonising the company rules, allowing for easy application and certainty. The general rule is that the twin set of shareholder and directors, through the doctrine of separation of ownership and control, play a critical role in running a company's affairs. Further, the reforms also brought judicial clarity for courts to interpret and apply the law with relative ease and legal certainty. These reforms became the cornerstone of corporate governance, with several commonwealth jurisdictions like South Africa’s 2008 Companies Act borrowing heavily from the UK. Correspondingly, the UK Companies Act has been pivotal in setting the scene for South African Companies Act. This study aims to conduct a qualitative research on the codification of the director’s duties in the UK Companies Act 2006, using legal theory. Thus, the empirical basis for this examination includes secondary sources, including a literature review of books, articles, case law and relevant Statutes. Both content and thematic analysis were employed. It is anticipated that the recommendations of this study could assist policy-makers, leaders and contribute to the body of legal knowledge
Nowcasting Madagascar's real GDP using machine learning algorithms
No full textWe investigate the predictive power of different machine learning algorithms to nowcast Madagascar's gross domestic product (GDP). We trained popular regression models, including linear regularized regression (Ridge, Lasso, Elastic-net), dimensionality reduction model (principal component regression), k-nearest neighbors algorithm (k-NN regression), support vector regression (linear SVR), and tree-based ensemble models (Random forest and XGBoost regressions), on 10 Malagasy quarterly macroeconomic leading indicators over the period 2007Q1-2022Q4, and we used simple econometric models as a benchmark. We measured the nowcast accuracy of each model by calculating the root mean square error (RMSE), mean absolute error (MAE), and mean absolute percentage error (MAPE). Our findings reveal that the Ensemble Model, formed by aggregating individual predictions, consistently outperforms traditional econometric models. We conclude that machine learning models can deliver more accurate and timely nowcasts of Malagasy economic performance and provide policymakers with additional guidance for data-driven decision making
Ab Initio Simulation Of The Structural, Electronic, Mechanical And Elastic Properties Of Some Transition Metals Yttrium (Yt) And Scandium(Sc)
No full textWe analyzed theoretically from first principle the structural, thermodynamic, electrical and mechanical properties of Yttrium and Scandium. We used the Density Functional theory to provide the solution to the Kohn – Sham equation.
The Xcryden software was used to obtain the structures of the elements studied in correlation within the PBE functions and were treated using the PAW pseudo – potentials and GGA to provide solutions between the core ions and valence electrons.
From the ab initio calculations, we observed that a(A), B(GPa), B’(GPa) and E(eV) for both elements studied are engulf in the structural parameters. Calculations for C11, C12 and C44 to obtain the mechanical properties and G, B/G, E, µ, A and H to obtain results for the elastic properties were also carried out for both metals.
The results obtained for Scandium shows that the values of B, C’, C11, C12 and C44 are 51.00, 4.00, 67.00, 43.00 and 32 respectively. For Yttrium we obtained 47.00, 4.07, 53.00, 40.20 and 22.00 corresponding to B, C’, C11, C12 and C44 respectively. The paper also provides results that agreed qualitatively with experimental data and other theoretical techniques discussed in the literature

Current Fish Feed Status and Development of New Feeding Technologies for Aquaculture Growth and Development in Kenya: Rapid Review
Get PDFAquaculture has emerged as a promising sector for addressing the ever-increasing demand for fish protein in Kenya, where over 50% of fish consumption is reliant on imports. However, the sustainable growth and development of aquaculture in Kenya are significantly influenced by the availability and quality of fish feed, which constitutes over 50% of the total production costs. The current fish feed status in Kenya is characterized by several challenges, including limited avail-ability of high-quality feed ingredients, high feed costs, and inconsistent feed quality and nutrient composition. These challenges pose significant constraints to the efficient production of healthy and marketable fish, limiting the full potential of aquaculture growth in Kenya. To address these challenges, efforts are being made towards the development of new feed formulations and feeding technologies that can improve the efficiency and sustainability of fish feed production in Kenya. This includes the utilization of locally available feed ingredients, such as agricultural by-products and aquatic macrophytes, to develop cost-effective and nutritionally balanced feed formulations. Moreover, research is underway to optimize feed processing techniques, such as extrusion, pelleting, and encapsulation, to improve feed quality, stability, and digestibility. Additionally, innovative feeding methods, such as automated feeding systems and precision feeding, are being explored to minimize feed wastage and maximize feed utilization, thereby enhancing fish growth and reducing production costs. The development of new feeding technologies for aquaculture growth and development in Kenya holds great potential to address the challenges associated with fish feed availability, quality, and cost. By optimizing feed formulations, processing techniques, and feeding methods, the aquaculture sector in Kenya can improve its productivity, profitability, and sustainability. However, further research, investment, and collaboration among stakeholders, including government, research institutions, feed manufacturers, and farmers, are essential for the successful implementation and adoption of these new feeding technologies to drive the growth and development of aquaculture in Kenya
