- Description: The literature clearly indicates that excessive amounts of salt and sugar, compared to the recommended amounts, are consumed by young children, leading to the earlier presentation of lifestyle diseases such as obesity, diabetes mellitus type 2 and hypertension (Lichtenstein et al., 2006; Grimes et al., 2013). The problem to address is that there is insufficient information available on the intake of sugar and salt in South African children, and more specifically in the Johannesburg and Port Elizabeth areas; this information is necessary to determine which prevention strategies should be developed. The aim of this study was to determine the current intake of salt and sugar of grade five learners at a sample of quintile three schools in Johannesburg and Port Elizabeth and to investigate whether there was a relationship between the sugar and salt intake and the BMI (kg/m2) and blood pressure (mmHg) of these learners. A baseline exploratory, quantitative, descriptive, cross-sectional study design was used. A non-random, convenient sampling method was used with a sample size of 220 consenting learners of Johannesburg and 350 of Port Elizabeth. A semi-quantitative adapted food frequency questionnaire was used to determine the current intake of salt and sugar in the learners. The data was analysed using the SPSS version 22 programme. Ethical clearance was obtained from the relevant bodies. The results were as follows: no significant differences were found between the frequency of consumption of any of the food items that were chosen to represent salt and sugar intake and blood pressure and BMI within either Johannesburg or Port Elizabeth. Therefore, no associations between salt and sugar intake and blood pressure and BMI were found within either area. When comparing the learners of Johannesburg with those in Port Elizabeth a few significant differences were found; mostly showing a weak association. However, there was a moderate association for sugar in tea/ coffee between the underweight and overweight/obese learners of Johannesburg compared to Port Elizabeth. Preferences, peer influence and food culture are suggested reasons for this significant difference. Recommendations of the study were the South African Food-based Dietary Guidelines “Use salt and foods high in salt sparingly” and “Use food and drinks that contain sugar sparingly and not between meals” should continue to be encouraged.

- Description: We live in the era in which the internet is now available on the majority of mobile phones at a very cheaper rate. This advancement in technology has created a boom in the use of mobile phone social networking as a primary communication tool - not only for individuals but also commonly used by professionals in most fields. The trends and growing usage of social networking via mobile phone indicate a potentially effective new platform for increasing production especially in agricultural sectors. In this age of information technology, farming communities can be empowered with the latest information and knowledge through mobile phone social networking to enhance agricultural development. The study investigates the use of mobile phone social networking as an extension tool in small-scale (emerging) farmers in selected farming communities in the Cacadu District Municipality of the Eastern Cape of South Africa. Specifically, the study investigates the use of available mobile phone social networks; what they are used for; and the importance and benefits of social networking both generally and to the farming communities. The study further identifies problems inhibiting the use of mobile phone social networking. Other channels through which the small-scale (emerging) farmers acquire agricultural information, aside from via mobile phone, and the type of agricultural information these farmers acquire, are also investigated. This study focuses on the use - and not the testing or adoption of - mobile phone social networking in small-scale (emerging) agriculture. In the exercise to investigate the use of social networking apps via mobile phone, data was collected from 40 small-scale (emerging) farmers using a purposive sampling method. This study used a survey design, exploratory and descriptive research methodologies. Data was captured by administering a questionnaire through personal face-to-face interviews. Descriptive statistics such as simple frequency tables, percentages and bar graphs were used. From the Chi-square testing, it was found that agricultural knowledge levels, internet access and size of production farm land influence the use of social networking by the small-scale (emerging) farmers. However, the result of this study showed that gender, age, other income and educational level of the small-scale (emerging) farmers are not statistically significant determinants of social networking use. Cronbach’s alpha coefficient was found to be 0.95. To establish the strength of associations of the variables, Cramer’s V ranging between 0.04 and 0.9 (signifying relationships from negligible to very strong association) was used. The findings showed that different social networks are used by the farming communities, such as WhatsApp, Facebook, and Blackberry messenger, MXit, Twitter and YouTube. The various uses of these social networks by the farmers are discussed. The benefits and problems inhibiting their use are also outlined. Other sources of acquiring agricultural information by the farmers aside from social networking via mobile phone are examined. The result of the study shows that [agricultural extension officers, other farmers, farmers’ discussion groups, friends and family,] are major sources of agricultural information to the small-scale (emerging) farmers while other sources are television, radio, print media and result demonstrations. The study suggests that to enhance mobile phone social networking to ensure that timely and effective agricultural information is readily accessible to the small-scale (emerging) farmers. These include agricultural extension officers making optimal use of social networking via mobile phone, due to the strong interaction and trust between them and the farmers. This interaction can be instrumental in the effective use of this technology as a resourceful medium for accessing agricultural information to enhance productivity. Proper awareness and understanding of the potential and benefits of mobile social networking by the farmers will motivate the small-scale (emerging) farmers to use the technology for effective agricultural purposes. Also, ensuring the availability of agricultural information to small-scale (emerging) farmers by setting up on-line pages or websites to discuss matters of interest and educate and update farmers on agricultural issues should be encouraged. This may attract the younger generation and the youth to participate fully in agricultural activities - thereby enhancing agricultural development.

- Description: The study focused on identifying ways in which to improve and increase the quality of training and supply of skilled artisans in the South African construction industry (especially in Gauteng Province) in terms of short and medium term approach. The construction industry is facing a severe skills crisis and this has made it so difficult to recruit competent artisans. This may be as a result of artisans being regarded as the lowest in the hierarchy of construction worker positions. In addition, these artisans warrant less training than those at executive- and managerial levels. This negative attitude towards artisans training has plunged the industry into crisis. Those involved find it difficult to successfully complete projects on time, within budgeted project costs and within the required quality specification due to lack of competent artisans. However, serious attention is required towards enhancing artisan training in the industry. It is imperative and vital to ensure the survival of the industry. The cardinal aim of this research project was to demonstrate a guiding solution towards the skills crisis. Thus, in order to initiate a tremendous change in the skills profile, certain measures are required, e.g. expanding training institutions to local regions; upgrading and aligning facilities in the training institutions to industrial demands and the dissemination of vital information that will ensure the attractiveness of the industry. This will safeguard the construction organisations operating in Gauteng Province. Although the industry is a major player in the economy, there is need for special attention in order to ensure sustainable growth and economic development. The Government, construction industry stakeholders and training institutions personnel should collaborate to salvage the skills crisis by strategically developing programmes (in accordance with industrial requirements) that will benefit prospective learners. The researcher adopted the descriptive- and analytical survey method, which entailed the use of questionnaires and a review of the related literature for gathering relevant data. The methodology used in the research was the quantitative data analysis. The feature findings of the research concluded that the skilled artisans profile is insufficient to meet industry demands. In addition, training institutions and primary- and secondary educational systems are characterized by ninadequacy and incompetency to produce skilled artisans. The situation is exacerbated by the lack of harmonization between the training institutions and the vindustry’s requirements. Furthermore, the majority of the respondents acknowledged that training of their workers is an important aspect to them, but few of these organisations indicated that they make use of formal training institutions such as FET colleges. The recommendation include that all the stakeholders in the construction industry should form collaborations to strategically develop programmes that would upgrade the existing training institutions. This could be done through provision of adequate funds and resources and the dissemination of vital information that is capable to promote the attractiveness of the industry image.

- Description: The cable manufacturing industry may not be well known to some people, yet people’s very lives depend on products and services it produces. Today people live in a highly technological or digital world where most of the technology used by society has at least one electrical cable in it or is connected to a countrywide electrical or communications network through electrical cables in order to work. Well trained and experienced corporate and business leaders recognize the importance of lean supply chain and of being closer to one’s business suppliers for efficient running of the business. Like in all other countries where these industries exist, it is vital that the cable manufacturing industry survives and prospers in South Africa, for the benefit of South African telecommunications, electricity suppliers, computer networks and many more industries. However, today there are almost no boundaries in business owing to globalization which enhances free trade. The business environment is changing and there is fierce competition amongst international rivals. What happens then when customers are not happy with low quality products of one supplier? Would they not leave that supplier and look to the competition in order to get good quality products at reasonable prices? Of course they would. Consequently such a supplier would lose market share and ultimately be forced out of business. This research investigates the shortcomings in terms of the implementation of the principles of total quality and technology management in the cable manufacturing industry. It identifies the internationally recognised principles in the fields of total quality management and technology management as a means of enhancing a competitive advantage. Training and development are identified as extremely important supporting mechanisms which should be done professionally for the best results in the implementation of total quality and technology management principles. Finally, suggestions and recommendations based on best management practice are made.
