Abstract: Promoting the continuous professional learning of university academics is key to the enhancement of student success in higher education (HE) and therefore a defensible practice. It is a practice that is predicated on the understanding that there is an inextricable link between student success and academic staff competence. Consequently, universities across the world have and continue to initiate various staff development programmes that are meant to enhance the competencies of academics as facilitators of learning. This concept paper examines how academics’ continuous professional learning can be enhanced through a practical framework known as the pedagogy of discomfort. The framework refers to a process that disrupts established and cherished practices in teaching and learning. The article explores how the pedagogy of discomfort can be nurtured through community of practices (CoPs) so as to raise the profile of teaching and learning. Examples are drawn from a new comprehensive university in South Africa. The article is derived from the author’s teaching experience in HE as well as current local and international literature and journal articles on academics’ professional learning. The main contention articulated is that academics need to invite their peers on a regular basis to critique and question their current teaching practices and ways of doing things as a means of invigorating their competences.

Abstract: This paper argues that many schools cannot easily address language diversity through multilingual education. Application of varying modes of delivery in a multilingual classroom, in many schools, more so to vast numbers of home language learners who are expected to learn an additional language not familiar to them, becomes a difficult adventure for teachers offering languages. The survey conducted by authors in selected schools from one of the education districts in the Eastern Cape province, South Africa, discovered a number of difficulties encountered by some language teachers and their pursuit of teaching learners in multilingual classrooms. In this article, questionnaires were administered to ten language teachers. Through interventions by the authors, participants were then required to contend whether there were any significant impacts of multilingual education with regards to language learning. Findings divulge that learners who received multilingual education were observed to be expressing a more encouraging attitude to language learning. Therefore, we recommend observance of some strategies to address challenges experienced in multilingual classrooms. Strategies recommended are aligned with language diversity and school policy imperatives. Finally, learning various languages is perceived as a social advantage that could improve communication amongst people from numerous cultures, as South Africa is a country noted for its distinctive characteristic of being a diverse cultural environment.

Abstract: This study aimed to explore the importance of corporate governance to the performance of Small and Medium Enterprises in Gauteng province, South Africa. The study focused on exploring the roles of corporate governance to SMEs sustainability, identifying the current practices among SMEs, identify the benefits of corporate governance to SMEs as well as to recommend strategies for effective adoption of corporate governance practices among SMEs. The study was done using the qualitative research approach. The exploratory research design was utilised. In the collection of data, semi-structured face-to-face interviews with SMEs in Gauteng Province were utilised. The study utilised a sample size of ten (10) participants; this was selected using a non-probability sampling technique, precisely, convenience technique. The collected data were analysed using the thematic analysis tool; themes and patterns were developed and presented in this study. The study found that there are several roles played by corporate governance in SMEs which include improving the competitiveness of SMEs and its role to improve the firm’s performance. The study found that small and medium enterprises are not practising corporate governance due to inadequate capabilities. The study revealed that there are no risk management practices in SMEs. There are no clearly defined roles and responsibilities and small enterprises are not emphasising integrity and ethical dealings. The research revealed that corporate governance increases access to resources; it paves way for future growth. It lowers the cost of capital and improves the management structure of entities. It improves the benefits of all stakeholders as well as the company’s reputation. Therefore, the study recommended that there should be the training of owners and managers to understand the benefits of corporate governance, frameworks need to be applied flexibly, taking account of the heterogeneous nature of small businesses as well as changing board structure and increasing the number of external directors.

Abstract: The main purpose of the present work is to improve the principal characteristics of gas turbine cycle used under hard condition of ambient temperature. That does allow controlling its functioning and recommending a reliable solution remedying at its drop in net power output. A thermodynamic model of gas turbine cycle was established on the basis of energy balance equations utilizing Matlab software. The effects of varying the operating conditions (ambient temperature, compression ratio, turbine inlet temperature, and air to fuel ratio) were investigated. The modeling results show that for each 5°C decrease of ambient air temperature, the net power output and the thermal efficiency of the gas turbine increase respectively around 3% and 1.5%. Also, the turbine net power output increases when the ambient temperature and the air to fuel ratio decrease. The value of gas turbine thermal efficiency is greatly improved when air to fuel ratio is at its minimum value. The maximum thermal efficiency occurs at the highest compression ratio with the lowest ambient temperature and the highest turbine inlet temperature. Furthermore, the addition of a component to the gas turbine cycle, injecting steam upstream of the combustion chamber, effectively improves its power output and thermal efficiency. So, the same net power output of 49.61 MW is obtained at 320 K as that of the cycle without injection at ISO temperature 288 K. The thermal efficiency is stabilized at 39.40% in the same temperature range 288-320 K. The modeling results obtained with the proposed model are in very close agreement with data published in the literature.

Abstract: This paper reports on a study exploring the teaching and learning of mathematics in a multilingual classroom at a Technical Vocational Education and Training College (TVET). A case study research method was used. Three N5 mathematics lecturers and 20 N5 students were purposefully selected from two campuses of a TVET college in South Africa. Data were collected using semi-structured interviews and through classroom observations. Lecturers were interviewed individually to find out the effects of the language of teaching and learning on student understanding, and to find out the teaching strategies they use to teach mathematics. Findings reveal that students know what they should do in order to understand mathematical concepts, although they do not always adhere to them, and they also know what they expect from lecturers. Lecturers also know the teaching strategies that could give them good results, but the students seem to not do their part. Findings also reveal that a common language between lecturers and students helps a lot in explaining some important mathematical facts and it also helps in improving participation during lessons.

Abstract: This article touches upon the topic of preserving traditional cuisine in modern Ossetia. Rituals associated with the preparation and consumption of food and drinks are an important part of the culture of an ethnic group, helping to preserve its identity and traditions. The introduction to the article reveals some of the traditional ways of preparing, serving and eating food and drinks, which reflect such properties of the Ossetian lifestyle as respect for elders, the greatest hospitality and deep religiosity. However, theory without practice is dead, so the main part of the article is based on the materials of an ethnosociological survey conducted in April 2019 by the Center for Research of Border Regions of the South of Russia ISPI FCTIS RAS with the participation of 500 respondents in the city of Vladikavkaz and other cities and villages of the Republic of North Ossetia - Alania. The data obtained show that traditional methods of cooking and drinking are widespread both in rural areas and in cities, and the residents themselves love traditional Ossetian cuisine and regularly prefer it. We believe that the distribution of Ossetian food serves not only to preserve traditions, but also attracts tourists, which in turn contributes to the development of the economy of the republic and the entire North Caucasus.

Abstract: The current study investigates the potential use of Algerian clay as an adsorbent for the elimination of Crystal Violet (CV) dye. Mchouneche Clay (MC) has been introduced as a low-cost biosorbent for batch manner removal of CV. Essential criteria were examined to determine the optimal conditions. In addition, several kinetic and isothermal models were fitted with experimentally obtained data. The uptake of CV correlated with the initial pH, due to the ionic nature of CV and the mineral surface of MC. Indeed, the adsorption behavior was found to depend on the initial concentration of CV as the number of collisions increased. The analytical study revealed that Pseudo-Second Order (PSO) is the most suitable fitting model. The isothermal study has also shown that the results are consistent with the Langmuir model. The thermodynamic investigation has shown that the adsorption phenomenon is feasible, spontaneous, and endothermic.

Abstract: This paper reports on the effect of using a concrete-method in the teaching and learning of integers in the Pixley Kaseme education district in the Northern Cape Province of South Africa to grade 7 learners. The concrete-method simplifies the procedure and the laws to calculate the integers using representations which slightly differs to the way sign rules are used in mathematics. This quantitative paper reports on the quasi-experimental research design which used the treatment group and the control groups. Two teachers’ two groups, one for the concrete-method while the other teacher for the sign rules. Cronbach alpha was used to calculate the reliability of the sign rules test and was 0,702, while the concrete method test reliability was 0.8479 and these values were deemed acceptable and reliable. The findings revealed a difference in performance between the sign rules and the concrete method on the posttest scores. The findings also revealed that the concrete-method had little effect on the teaching and learning of integers as compared to the sign rules. The study recommends the use of C-method as an alternative to the concrete method, hoping that it would yield better results.
