Efficacy of three anticoagulant rodenticides for the control of poison-shy Rattus rattus

House rats (Rattus rattus) which do not consume a lethal dose of zinc phosphide develop poison-shyness after a single exposure. The surviving poison-shy rats cannot be baited again with zinc phosphide for about three months. Poison-shy rats were separately given anticoagulant baits (brodifacoum 0.005%, coumatetralyl and warfarin 0.025%) in no-choice tests. The first two anticoagulants were found to be the most efficient ones. It was observed that those R. rattus which had consumed 56.7 mg/kg or more zinc phosphide died sooner (P < 0.05 to 0.1) after anticoagulant poisoning when compared with normal rats. It is conjectured that prothrombin inhibition is accelerated in the liver of poison-shy R. rattus due to the action of phosphine present in the earlier ingested sublethal dose of zinc phosphide

Barriers to Socio-economic Opportunities in Africa: An e-Government Perspective

Various barriers to socio-economic opportunities in Africa are explored though e-Government as a lens of study. Using grounded theory methodology, scholarly literature on e-Government in Africa has been analyzed to model various barriers. The research is expected to serve as a scholarly reference for decision-makers in the private and the public sector organizations, as well as policymakers, for making decisions about design, development and execution of e-Government initiatives in Africa

Non-compliance, board structures and the performance of financial firms during crisis: UK Evidence

This paper examines the effectiveness of internal corporate governance mechanisms for improving the performance of financial firms in the UK. The research is first of its kind to look into the relationship between corporate governance and performance of financial firms in the UK before and during the financial crisis. Using Generalised Methods of Moments (GMM) estimates that control for dynamic endogeneity, this study shows that firm performance as measured by Total Shareholder Returns (TSR) and Return on Equity (ROE) is negatively associated with the level of non-compliance with the UK Corporate Governance Code. The study also finds that having higher number of internal controls is most effective monitoring mechanism and is positively associated with firm performance. However, board independence represented by the number of non-executive directs (NEDs) is the least effective monitoring mechanism and is negatively associated with the performance of firms. The study also shows that directors’ share ownership is an effective incentive mechanism for aligning their interests with shareholders as it is positively associated with firm performance. However, the findings suggest that remuneration is negatively associated with performance. Finally, the study provides evidence which indicates that board size impact the performance of firms differently in different time periods. As proposed by agency theory the study provides evidence that shows the positive impact of effective monitoring and incentive alignment for performance. It also provides support for the resource dependence view that directors are a critical resource during difficult economic times
