The utilization of unused and retired mobile phones in South Africa and other African countries poses a significant environmental hazard. Disposing of retired mobile phones in a safe manner has become an issue of concern in South Africa because of health and environmental hazards associated with it. This study investigates the methods of disposing and recycling of old, unused and retired mobile phones and their associated environmental effect on humans and plants in Africa. A case study approach was used in this paper. Participants were selected from three cities in South Africa, targeting three government institutions and three mobile phone service providers. Semi-structured, open-ended interview questions were used to get evidence from the participants regarding how old, unused and retired mobile phones are disposed and possible effect of these on the environment. The interviews were recorded, transcribed and coded. Findings revealed that most common method of disposing of old, retired mobile phones was donating them as gifts, selling to second-hand shops or storing in homes as spare phones. Based on findings, a proposed framework was developed to guide the collection process, reducing, reusing and recycling of old and retired mobile phones in Africa. The framework will not only assist manufacturers and retailers in selecting a better option of disposing old mobile phones, but also will to improve the hazardous environmental conditions, which affect humans and plants.

The Home Visit Method is a learning method that can be used during the Covid-19 pandemic. Various obstacles that hinder the implementation of online learning, namely poor network connection, and the lack of online learning facilities such as cellphones and internet quotas as well as the ability of students to use android mobile phones. so that the MTS Jam'iyah Mahmudiyah Tanjung Pura Langkat school implements an offline learning policy, where teachers conduct offline learning by visiting students from house to house in each group. This type of research is quantitative with a case study approach. The data collection method is done through observation, questionnaires and documentation. The population in this study were students of class VIII MTS Jam’iyah Mahmudiyah and the research sample was 48 students. The results of these findings are that there is an effect of the s home visit method on the learning outcomes of the class VIII students of MTs Jam'iyah Mahmudiyah Tanjung Pura Langkat with a total presentation of 64.58% and in the moderate category on the learning outcomes of Al Qur'an Hadith which is carried out continuously offline. The home visit method process is an alternative to learning during the Covid-19 pandemic.

This paper contributes to the understating of tornadoes in South Africa using case study analysis. In South Africa tornadoes are the recurring phenomenon (the climatology) but so far they have received less attention. Damages from storms itself (tornadoes inclusive) are significant in South Africa relative to other weather-related disasters for example floods, heat waves, and droughts. For their understanding, a case study approach was adopted in the current study. Data were in courtesy of the following, National Oceanic and Atmospheric Administration (NOAA), National Centers for Environmental Predictions (NCEP), Eumetsat Germany, and South African Weather Service (SAWS). The aim of the study was to provide an overview of the occurrence of tornadoes in South Africa using a Klerksdorp tornado, which occurred on March 4, 2007, Northwest Province in South Africa. From the case study analysis, the tornado was associated with the cold front and cut-off low (both are extratropical circulation) which were the dominant weather systems of the day. Therefore we conclude that, a case study approach may be the best way to study events of these nature for a more informed decision, for example, issuing an early warning system.  In future, case studies, for example, involving interaction between extratropical and tropical circulation will also be an interesting study.

A telematics device is a vehicle instrument that comes preinstalled by the vehicle manufacturer or can be added later. The device records information about driving behavior, including speed, acceleration, and turning force. When connected to vehicle computers, the device can also provide additional information regarding the mechanical usage and condition of the vehicle. All of this information can be transmitted to a central database via mobile networks. The information provided has led to new services such as Usage Based Insurance (UBI). A range of consultants, industry commentators and academics have produced an abundance of projections on how telematics information will allow the introduction of services from personalized insurance, bespoke entertainment and advertise and vehicle energy optimization, particularly for Electric Vehicles (EVs). In this paper we examine these potential services against a backdrop of nascent regulatory limitations and against the technical capacity of the devices. Using a case study approach, we examine three applications that can use telematics information. We find that the expectations of service providers will be significantly tempered by regulatory and technical hurdles. In our discussion we detail these limitations and suggest a more realistic rollout of ancillary services.

Background: Southern African countries adopted diverse responses to the challenge posed by the COVID-19 pandemic outbreak, which manifested itself as both a health and economic disaster.Aim: Using a case study approach of two South African countries, namely Botswana and South Africa, the article assessed their response measures to the COVID-19 pandemic.Setting: Southern African countries applied ‘domesticated’ forms of responses thus, there has been no one-size-fits-all approach to managing the pandemic.Methods: The study adopted a qualitative approach. Two case studies namely Botswana and South Africa were used. Documentary evidence was drawn from these case studies.Results: To ensure that Southern African countries and indeed the world in general navigate the challenges posed by the COVID-19 pandemic, the World Health Organization (WHO) developed operational planning guidelines that had sought to balance the demands of responding effectively to COVID-19 and the need to serve economies from collapse. However, an analysis of the programmes of responses in South African countries such as Botswana showed the ‘domestication’ of the guidelines. Nevertheless, the guidelines, although having met with criticism in some cases had significantly contributed to the effective management of COVID-19 health and economic effects.Conclusion: The COVID-19 pandemic required the state and its institutions to exercise effective leadership and unified action. In South African countries such as Botswana and South Africa, this pandemic showed the importance of governments in shaping the effectiveness of national responses, strategies and approaches in tackling the crisis.

Disposal of obsolete computers (DOC) in higher institutions in Africa poses a major environmental problem to many African people. The question of how to dispose obsolete computers and computer technologies in a safe manner has become a cause of concern to many African people, especially when toxic emissions pollute the air, water, and soil posing a serious health and environmental hazard to the community. This study investigates the methods of disposing and recycling of obsolete computers, and its environmental effect on plants and animals in Africa. A case study approach is used. Participants were selected from three African countries Ghana, Nigeria and South Africa based on their historical background in Africa regarding e-waste. Semi-structured, open ended interview questions were used to gather evidence from the participants regarding how obsolete computers are disposed from their institutions and the possible effect of the disposed computers on the environment. The interviews were recorded, transcribed and coded. The findings revel that the most common method of disposing obsolete computers is through dumping, dismantling of parts for resale by children and open field burning of unwanted parts. This burning process produces toxic material which is associated with high health risks. Based on the findings, a proposed Disposal of Obsolete Computers Framework (DOCF) was developed to guide higher institutions in Africa to opt for appropriate methods of disposing computers. The framework will not only assist higher institution in selecting a better option of disposing obsolete computers, but also will improve the hazardous environmental conditions which animals and plants find themselves
