<p><strong>Abstract.</strong> The changes to the landscape are constantly occurring both naturally and human induced. One of such changes is the human settlement expansion. The ability to map human settlements is vital for variety of studies including urban development planning and management. For this study human settlement detection is essential for topographic map update. The newly identified human settlements also serves as change detection area indicator for further update of other topographic features that are represented on the topographic map (such as roads etc.).

Abstract:
Estimating the number and size of irrigation center pivot systems (CPS) from remotely sensed data, using artificial intelligence (AI), is a potential information source for assessing agricultural water use. In this study, we identified two technical challenges in the neural-network-based classification: Firstly, an effective reduction of the feature space of the remote sensing data to shorten training times and increase classification accuracy is required. Secondly, the geographical transferability of the AI algorithms is a pressing issue if AI is to replace human mapping efforts one day. Ther

A comprehensive literature review of psychographics is undertaken. In addition, a review of segmentation techniques used in South Africa is given.

The results show that there is a low level of understanding of psychographics as a segmentation technique by both groups.

It is therefore a viable option but requires more research, management, planning and control for it to be successful. Many agritourism ventures are not as successful as they should be.

This progression, which is characterized by various stages and varying consumption portfolios, can be traditional or non-traditional in nature. In the general marketing sense, the FLC concept has great value. The concept is utilized in a variety of marketing activities, particularly in segmentation, and is also applied in consumer behaviour. The lack of research regarding the FLC in South Africa and the need to investigate the concept’s applicability to different environments motivated this research. The aim of the study

However, show ticket sales have declined in recent years which, if this trend continues, will result in the discontinuation of these festivals.

Beginning in the fifteenth century, people, plants, pathogens, products, and cultural practices — just to mention some key agents — began to move regularly back and forth across the Atlantic Ocean. As the connections and exchanges deepened and intensified, much was transformed. New peoples, economies, societies, polities, and cultures arose, particularly in the lands and islands touched by that ocean, while others were destroyed.

Yet achieving this equality is proving an uphill struggle in self-proclaimed democracies supposedly committed to egalitarian principles.

Abstract:
Funding for vocational skills development is important for effective development of graduate competencies. A comparison of literature on funding models in Botswana, SA, and Zimbabwe reveals common models with alternatives augmenting predominant systems. Funding in the three countries is predominantly through public funding and levy-grant system. Other funding sources include income generating activities, corporate and donor funding, fees from students and student grant-loan schemes. Some challenges in TVET funding include fragmented financing systems, general high cost of financing TVET, lack of commitment by stakeholders, poor image of TVET against academic education, inadequate public budgetary allocations by most governments, lack of research and feedback to TVET planners from labour market to allow planning and adjusting funding models for future skilled manpower requirements. There is need to have adequate funding to ensure that graduates fully gain the necessary competencies.

It defines a hustler as someone who tries, and talks about what entrepreneurship is like in South Africa. It discusses the difficulties that aspiring African entrepreneurs encounter as they try to become successful in their business. It talks about the lack of pride the new generation of South Africans have and how this has affects their attitude towards work and how this impacts African society. It talks about survivalist improvisation, how Africans put up an image of dignity in the midst of struggle, and their feelings of being trapped in that situation.

This study shows that cyber crime is a recent addition to the list of crimes that can adversely affect businesses directly or indirectly. This phenomenon was not directly prosecutable in South Africa until the enactment of the ECT Act in July 2002.

Therefore very little research appears or has been documented about cyber crime in South African companies before 2003. The motivation to do this study was that businesses often loose m
