Modeling Memorization and Forgetfulness Using Differential Equations

{\bf Research Context}: The aim of the study was to use differential equations to model memorization of students based on a given data taking into account forgetfulness.\\\noindent {\bf Research Methods}: The purpose of this paper was to decipher the rate at which students memorized the stuff that required memorization in the area of axioms and proofs of theorems as well as considering the fact that they will forget some of them along the way. The usage of differential equation was employed to model the trend. The paper contributes to the literature by documenting that students can memorize large number of stuff even beyond their perceived imaginations.\\\noindent {\bf Conclusion}:  This study employed the usage of differential equations to model the rate at which students could memorize a given number of axioms and proofs, considering the fact that they will forget some of them along the way. Persons who are able to absorb and retain more are able to recollect better than those who can absorb more and retain less.  On the other hand, those who can absorb less and retain more have an upper hand in recollection over those who can absorb more and retain less. Consequently it is better to have a higher retention constant than a higher absorption rate. Factors like the learning strategy, learning materials, learning environment, study mates have either a positive or negative influence on an individual's absorption and retention in the long term

Developing and maintaining national food safety control systems: Experiences from the WHO African region

The establishment of effective food safety systems is pivotal to ensuring the safety of the national food supply as well as food products for regional and international trade. The development, structure and implementation of modern food safety systems have been driven over the years by a number of developments. These developments include: a reorientation of quality assurance protocols; emphasis on the development of integrated and holistic food safety systems with a farm-to-table approach; increasedrecognition of the respective roles of the different stakeholders along the food chain; increased food trade coupled with obligations under trade agreements; and advances in the control of foodborne hazards. At its core, a modern food safety system includes enabling food laws, policies, regulations and standards; mechanisms for coordination; operational food inspection and laboratory services as well as national information,education and communication programmes. While progress has been made in some countries in the WHO African Region at modernizing their food safety systems, many others are still grappling with the basics for development of effective food control systems. The traditional food control systems in a number of African countries do not provide the concerned agencies with a clear mandate and authority to prevent food safety problems. Effective food control in a number of these countries is undermined by a number of challenges including limited awareness about food safety, inadequate enabling policy, outdated legislation and regulations; inadequate coordination; and inadequate capacity and resources for food safety. This paper reviews the components of a modern national food safety control system and examines efforts at strengthening national food safety control systems in the African Region. It includesexperiences from countries that have made efforts at strengthening their national food safety control systems in view of current developments. The paper further discusses some of the challenges of food control systems in the Region and prospects for improvements. It concludes by suggesting the way forward for improving national food safety control systems in the Region
