“…In order to have a better grasp on the population that is the main object of this study, i.e., the students, other studies that could shed light on the students' sustainable electricity behaviors were investigated. Students' electricity patterns have been studied by researchers in the USA [39], South Africa [40] and the Netherlands [41], among others, with the purpose of understanding the variables in energy use by the students. Still, these studies do not discuss the existence of sustainable electricity consumption among students.…”

The Organization for Economic Co-operation and Development (OECD) estimates that the environmental pressure from households will increase significantly by 2030. Sustainable consumption means making consumers aware of the social and environmental impacts of the goods and services they use. In this respect, special attention must be paid to electricity consumption since its generation affects the environment. The present research aims at capturing electricity consumption behaviors among students, after having applied an online questionnaire between March and April 2021, recording 816 responses. The results of this research highlighted the fact that for seven out of fourteen statements, percentages of over 50% for the “always” and “often” answer variants were recorded, but cases when the highest percentages were for the “rarely” and “never” answer variants (e.g., “You read the hours on the light bulb packs before purchasing them”, “You put your mobile phone in the power saving mode so that you don’t have to charge it so often” and “You unplug the electrical and electronic equipment that you do not use”) were also observed. Decrypting consumer behaviors is a key point for building strategies that will lead to consumers’ awareness of conserving electricity in households and, thus, to a reduction in their environmental impact.

“…Furthermore, the hourly energy consumption of the student residence which covers the four major SA seasons, namely, autumn (1 March-31 May), winter (1 June-31 August), spring (1 September-30 November), and summer (1 December-28/29 February) were obtained for the year 2017. Te energy consumption data for the student residents were obtained from the study of Masebinu et al [52]. Located on campus, the student residence has 17 rooms (including a kitchen and a washing area) and 4 toilets and bathrooms.…”

“…Located on campus, the student residence has 17 rooms (including a kitchen and a washing area) and 4 toilets and bathrooms. Te data comprise realtime power consumption and are a time-series dataset acquired from real-time energy monitoring equipment from the student residence's distribution panel [52]. Figure 2 shows the architectural design of the model under study.…”

Future energy planning relies on understanding how much energy is produced and consumed. In response, this study developed a multihybrid adaptive neuro-fuzzy inference system (ANFIS) for students’ residences, using the University of Johannesburg residence, South Africa as a case study. The model input variables are wind speed, temperature, and humidity, with the output being the equivalent energy consumption for the student housing. While the particle swarm optimization (PSO) technique is versatile and widely used, it falls short by exhibiting premature convergence. To address this problem, the velocity update equation of the original PSO algorithm is modified by incorporating a dynamic linear decreasing inertia weight, which improves the PSO algorithm’s convergence behaviour and aids both local and global search. Following that, the modified PSO (MPSO) is used to optimize the ANFIS parameters for the best model prediction. A comparative analysis is conducted between the MPSO, the original PSO, and six other hybrid models using a dataset division of 70% for training and 30% for testing. Performance evaluation was carried out using three well-known performance benchmarks: root mean square error (RMSE), mean absolute deviation (MAD), and coefficient of variation (RCoV). The experimental results show that the performance of the proposed MPSO-ANFIS outperformed other methods with the least values of the RMSE (1.8928 KWh), MAD (1.5051 KWh), and RCoV (0.1370), respectively. Furthermore, when compared to the PSO-ANFIS, the MPSO-ANFIS demonstrated improvements in RMSE, MAD, and RCoV with 1.58%, 2.11%, and 5.23%, respectively. Based on the results, it can be concluded that the MPSO-ANFIS provides better prediction accuracy which is vital for strategic energy planning.

“…Unlike the majority of students at the institution, due to the software requirements of the student's major, arrangements had been made for this particular subset of students to have comprehensive access to the internet. Whilst students did struggle with internet connectivity, and in particular the impacts of load-shedding 3 (Masebinu et al 2020), I could assume a degree of digital literacy in the class itself. It also meant that I was able to undertake synchronous teaching at a moment when that was rarely possible at the South African undergraduate level, in addition to significant interaction and support via the university's electronic learning platform as well as WhatsApp.…”

This article uses a student assessment developed in the “emergency” conditions of the Covid-19 pandemic in South Africa as a tool for refracting and reflecting (Strassler 2011) the changing realities of higher education around the world. It examines the Archive of Kindness as an example of the possibilities enabled by digitally mediated learning, as well as the challenges of teaching and learning in environments where students enter university with varying degrees of digital literacy and skill. It poses questions pertaining to the futures of higher education in a world in which biopolitics are increasingly determined by and through screens, and suggests that uncritical engagements with digital platforms and the corporate entities behind them pose dangers to emerging forms of citizenship. The article details the processes of knowledge curatorialism which are increasingly likely to determine the shape of learning in tertiary education, particularly within the university sector. Here, it argues that the Humanities and Social Sciences will need to play a leading role in providing the language and tools for thinking through the pedagogy of hyperlinkages, where the boundaries between online and offline spaces are increasingly difficult to parse.
