Abstract:
Abstract Dewatering associated with mining in the gold-bearing reefs of the Far West Rand, which underlie dolomite and unconsolidated deposits, led to the formation of sinkholes and subsidence depressions. Hence, certain areas became unsafe for occupation and were evacuated. Although sinkholes were initially noticed in the 1950s, the seriousness of the situation was highlighted in December 1962 when a sinkhole engulfed a three-story crusher plant at West Driefontein Mine. Consequently, it became a matter of urgency that the areas at risk of subsidence and the occurrence of sinkholes were delineated. Sink-holes formed concurrently with the lowering of the water table in areas which formerly had been relatively free of sinkholes. In addition, subsidence occurred as a consequence of consolidation taking place in the unconsolidated deposits as the water table was lowered. In the latter case, the degree of subsidence which occurred reflected the thickness and original density of the unconsolidated deposits which were consolidated. These deposits vary laterally in thickness and thereby gave rise to differential subsidence. Subsidence also occurred due to the closure of dewatered voids at the rock-soil interface. The risk of sinkhole and subsidence occurrence is increased by urban development, since interrupted natural surface drainage, increased runoff, and leakage from water-bearing utilities can result in the concentrated ingress of water into the ground. Where the surficial deposits are less permeable, the risk of instability is reduced. In the area underlain by dolomite, which extends around Johannesburg and Pretoria, these problem have been more notable in recent years because of housing development, both low-cost and up-market, and the growth of informal settlements. Residential densities may be very high, especially for low-cost housing, the development of which frequently has proceeded without recognition of the risk posed by karst-related ground instability. The appearance of significant numbers of small sinkholes has been associated with dolomite at shallow depth, that is, occurring at less than 15 m beneath the ground surface. The vulnerability of an area overlying dolomite bedrock at shallow depth is largely dependent on the spacing, width and continuity of grikes. When dolomite is located at depths greater than 15 m, the sinkholes which appear at the surface usually are larger in diameter. The risk of sinkhole occurrence in areas of shallow dolomite in general, may be greater, although the hazard itself is less severe. A classification system for the evaluation of dolomitic land based on the risk of formation of certain sized sinkholes has enabled such land to be zoned for appropriate development. Ongoing monitoring and maintenance of water bearing services, and the implementation of precautionary measures relating to drainage and infiltration of surface water are regarded as essential in developed areas underlain by dolomite. Special types of foundation construction for structures are frequently necessary.

Abstract:
The demand for data usage in South Africa is growing and this growth is creating a heavy demand on the network of telecommunication providers. The challenge facing South Africa is a lack of spectrum especially for high-speed access of Long Term Evolution networks, which creates a set of challenges in providing services to their customers for these telecommunication providers. The paper presents a narrative to ascertain where consumers in Gauteng access WiFi on a regular basis, how often they access these WiFi hot spots, reasons for their access. The findings would reflect the consumers’ buying behaviours as the target population to discover trends and patterns using WiFi. A qualitative methods approach was chosen. This was based on the buying behaviour, trends and patterns of WiFi users and how Telecommunication Service Providers and businesses could position themselves as a WiFi provider and capture this market. Respondents were regular users of WiFi and had good knowledge and understanding of WiFi. The biggest benefit of WiFi hotspots to them was that it was free and conveniently located and saved them on their personal data usage. Whilst there is a sporadic WiFi footprint available in Gauteng, the service needs to be expanded and made more accessible in all restaurants, taxi ranks, universities, shopping malls, gated communities. WiFi can be provided to cover a wider range at shopping malls by Telecommunication Service Providers partnering up with providers of public and private WiFi hotspots.

Abstract:
Rapid urbanisation brings unwelcome negative impacts, and places excessive pressure on infra-structure development and maintenance. In partic-ular, transport networks become congested with negative impacts on energy logistics. The liquid fuel situation of South Africa and Gauteng is briefly examined. The paper considers the impact of con-strained oil supply, and supply infrastructure, on transport. The author further suggests that the authorities in Gauteng should critically examine an ultra light rail option in order to reduce reliance on imported oil, while helping reduce road congestion. A more energy efficient transport network for the province, able to meet the transport needs of pas-sengers and business, will help decrease environ-mentally damaging emissions.

Abstract:
Abstract. Sinkholes are alarming and dangerous events, they have a worldwide occurrence, and are imposing a potential risk to urban communities and the widely developed built environment. Losses due to catastrophic sinkhole collapse, foundation, pavement and structural repairs, occur more often, due to the increased pressure to develop even on sinkhole prone land, and the aging of existing water supply infrastructure in the majority of cities. Remote sensing earth observation methods have proved to be valuable tools during the last two decades in long-term sinkhole hazard assessment. Satellite air borne and ground earth observation methods have primarily facilitated the wide detection of continuous displacement on the earth's crust. National sinkholes catalogues are necessary for town planers decision makers, and government authorities. In many instances the ground collapse is the result of water ingress from old poorly maintained leaking pipelines, or extensive dewatering activities. In the current study a comprehensive review of the current literature is presented in order to show experiences from South Africa and present recent mapping using PSInSAR methodology in Centurion South Africa.

Abstract:
AbstractRecent scholarship highlights the global expansion of precarious layers of the working class. This article examines the growth and collective struggles of such precarious layers in two very different places: California, United States and Gauteng, South Africa. The comparison challenges and extends existing research in two ways. First, it shows that the spread of insecurity is far from uniform, taking different forms in different places. Lack of citizenship is more crucial for workers in California, whereas underemployment is more crucial for workers in Gauteng. Second, it shows that insecure segments of the working class are capable of developing collective agency. This agency may be rooted in identities that extend beyond precarious employment, and will reflect the particular forms of insecurity that are prevalent in the given context. Such diversity is illustrated by examining May Day protests in California and community protests around service delivery in Gauteng.

Abstract:
Extensive research has been done on the investigation, evaluation, development and management of land underlain by dolomite to prevent the formation of sinkholes and subsidences. Little emphasis is, however, given to the various processes and methodologies with respect to the investigation and rehabilitation of sinkholes or subsidences. In South Africa most sinkholes and subsidences have been recorded on dolomite of the Malmani Subgroup of the Chuniespoort Group on the Far West Rand and in an area south of Pretoria within the City of Tshwane, with numerous studies done on the occurrence of sinkholes and subsidences in these two areas. However, a large number of sinkholes and subsidences have also been recorded on the East Rand in the Ekurhuleni Metropolitan Municipal area, which is the focus of this research. Very little is published on the occurrence of sinkholes and subsidences, the related geological models, investigations and rehabilitation work done in the Ekurhuleni Metropolitan Municipal area. It has been attempted with this thesis to document the various processes and methodologies applicable to the investigation and rehabilitation of dolomite-related sinkholes and subsidences within a non-dewatering environment. This is based on experience gained during the investigation and rehabilitation of various sinkholes and subsidences within the Ekurhuleni Metropolitan Municipal area on the East Rand, over the past ten years. Various methods of investigation, including non-intrusive and intrusive methods have been tried and tested to determine the extent of subsurface erosion within an affected sinkhole or subsidence area. The gravity geophysical method in association with the drilling of percussion boreholes; exposure of the affected area by means of excavation and the use of the Dynamic Probe Super Heavy (DPSH) method, in areas not accessible for a drilling rig where gravel, cobbles and boulders are absent in the subsurface profile; is the most appropriate methods for sinkhole or subsidence investigations on the East Rand. The gravity method is, however, not always successful in delineating narrow grykes in a shallow dolomite environment. The use of a specific method or methods of investigation is prescribed by the accessibility of a site. Accessibility constraints within a build-up area, may lead to the use of an investigation method other than what is generally preferred. The specific method or combination of methods used to rehabilitate a sinkhole or subsidence will depend on the available funds, current and proposed land use, subsurface conditions, accessibility constraints caused by existing infrastructure for equipment and the impact of the rehabilitation procedure on existing infrastructure. The various sinkhole and subsidence rehabilitation methods used on dolomite in South Africa and their applications are discussed, including: the Inverted Filter Method, Dynamic Compaction Method, combination of the Inverted Filter and Dynamic Compaction Methods, Compaction (backfill) Grouting Method, Combination of the Inverted Filter and Compaction Grouting Methods, Combination of the Dynamic Compaction and Compaction Grouting Methods and the use of Self- Compacting Concrete or Soil-cement Mix. Nearly half of the Ekurhuleni Metropolitan Municipal area is classified as dolomite land. A total of 241 ground movement incidents had been recorded, since 2005 to mid-2013. The Ekurhuleni Metropolitan Municipal area of jurisdiction is divided into three regional areas, namely:  Southern Regional area: More than 50% of the region is directly underlain by dolomite and chert of the Monte Christo Formation of the Malmani Subgroup of the Chuniespoort Group. A total of 141 ground movement incidents had been recorded, with all dolomite-related sinkholes and subsidences caused by ingress of water. Approximately 85% were caused by sewer lines, 7% by leaking water lines and valves, 4% by surface water ponding and 3% by concrete stormwater lines.  Northern Regional area: The northern portion of the region is directly underlain by dolomite of the Malmani Subgroup; from west to east by, chert-poor dolomite of the Oaktree Formation, chert-rich dolomite of the Monte Christo Formation, chert-poor dolomite of the Lyttelton Formation and chert-rich dolomite of the Eccles Formation. Dolomite of the Monte Christo Formation is also encountered in the south-eastern portion of the region. A total of 83 ground movement incidents had been recorded. Ground movement incidents are related to both ingress of water and dewatering of dolomite groundwater compartments including the Bapsfontein, Elandsfontein and Sterkfontein-East Dolomite Groundwater Compartments and Sub-Compartment.  Eastern Regional area: More than 50% of the region is regarded as dolomite land, with large portions of dolomite of the Monte Christo Formation and the Oaktree Formation of the Malmani Subgroup covered by the Karoo Supergroup. Dolomite of the Monte Christo Formation also occurs in the south-western portion of the regional area. A total of 17 ground movement incidents had been recorded. None of the recorded ground movement incidents are, however, related to dolomite. Incidents are related to poorely backfilled old wet services, natural erosion of subsurface soils, collapse of shallow coal workings and collapse of mine shafts and ventilation shafts. The sinkhole and subsidence rehabilitation method mostly used in the Ekurhuleni Metropolitan Municipal area is the Inverted Filter Method accounting for 85% of rehabilitation work, 10% for compaction grouting and 5% for the use of the Dynamic Compaction Method. The sinkhole and subsidence rehabilitation method should not be prescriptive, given the vast number of variables involved. A comprehensive understanding of the affected area is essential although for cost effective and practical rehabilitation measures. A site specific set of criteria for the rehabilitation of the features and affected infrastructure must be developed to ensure proper stabilisation and safe future use of the area. Basic principles can however be applied to each sinkhole or subsidence, such as: Ensuring the trigger of the sinkhole or subsidence has been identified and removed; the position and extent of the receptacles have been determined as best as possible and erosion paths sealed; the known eroded area, possible voids and cavities properly backfilled and densified; a proper impervious or engineer designed earth mattress created; ensuring that all affected subsurface wet services are replaced and comply with industry standards; and that proper surface drainage exists.

Abstract:
Includes bibliographical references.
Sinkholes encompass the withdrawal of shallow sediment into deep hollow compartments located in karstic stratum. These subsequent surface openings associated with karst geology have inhibited multiple infrastructure developments. Sinkholes are triggered by the alteration of the existing groundwater level which erodes weathered altered dolomite (WAD) residuum into karst cavities. Substantial literature has explored the stability of sinkholes, with reliance on limit analysis and empirical data, to quantify the strength of the porous karst residuum. In this study, the appraisal of sinkhole propagation was facilitated with the geological data acquired along the Gautrain route through Centurion, South Africa. Sinkhole development was analysed through analytical theories and the application of numerical methods. The analytical study conceptualized the ‘angle of draw’ of dolomite overburden layers into cavities, with Terzaghi’s arching in soil equation. The analytical results illustrated constant vertical drawdown in the WAD and incremental cavity propagation in the frictional chert residuum.

ENGLISH ABSTRACT: The development corridor concept has been regarded as an important development instrument in spatial planning and geography for many decades. Expanding literature on the theme indicates that development centres or nodes play an important role in the establishment of such corridors. Flows of goods and information between such centres are key in creating conditions that are potentially favourable for further urban development along the communication axes connecting such centres. Combined, the various nodes form a unique flexible exchange environment allowing for dynamic synergies of interactive growth that can achieve scope economies aided by fast and reliable corridors of transport and communication infrastructure. In the South African development sphere, there is strong belief that functional relationships between nodes can play a decisive role in the establishment of development corridors. This research showed that the degree to which economic activities are concentrated in the greater Gauteng region; the resulting current or emerging multinodal structural composition; and the flows of economic activities between the various nodes result in the creation of developing corridors that channel and focus economic growth between networks of cities. This confirms the importance of corridors as spatial and economic development instruments. The research concluded that corridor development in Gauteng still favours monocentrism. Johannesburg and Pretoria feature as the most dominant nodes, exerting great forces of attraction on the distribution of development and economic growth in the region. The research also suggests a degree of polycentrism whereby economic growth is channelled between networks of cities, however development potential is most favourable in areas in close proximity to primary centres and tends to be functionality driven.
AFRIKAANSE OPSOMMING: Die ontwikkelende korridor-konsep is oor baie dekades heen as ‘n belangrike instrument in ruimtelike en geografiese beplanning beskou. Uitgebreide literatuur dui aan dat nodusse ‘n belangrike rol in die vasstelling van korridors speel. Die vloei van goedere en inligting tussen nodusse is uiters belangrik in die samestelling van toestande wat gunstig is vir ontwikkeling rondom kommunikasie-asse wat nodusse verbind. Die kombinasie van nodusse vorm ‘n unieke vloeibare omgewing waarin medewerkende interaksie die omvang van ekonomiese groei bepaal en word ondersteun deur vinnige, betroubare vervoer- en kommunikasie-infrastruktuur. In die Suid Afrikaanse ontwikkelingskonsep, word sterk geglo dat funksionele verhoudings tussen nodusse ‘n belangrike rol kan speel in die vasstelling van korridors. Die navorsing toon dat die wyse waarop ekonomiese aktiwiteite binne die Gauteng-streek versprei is; die huidige of opkommende samestelling van meervoudige nodusse; en die vloei van ekonomiese aktiwiteite tussen nodusse die skepping van korridors wat ekonomiese groei tussen netwerke van stede kanaliseer tot gevolg het. Dit bevestig die belangrikheid van korridors as ruimtelike en ekonomiese beplanningsinstrumente. Die navorsing kom ook tot die gevolgtrekking dat korridorontwikkeling in Gauteng steeds die konsep van monosentrisme aanneem met Johannesburg en Pretoria as die mees dominante nodusse, wat groot aantrekkingskragte op die verspreiding van ontwikkeling en ekonomiese groei in die streek uitoefen. Die navorsing dui ook aan dat daar tog ‘n mate van polisentrisme is waardeur ekonomiese groei tussen netwerke van stede versprei word. Die mees gunstige ontwikkelingspotensiaal lê egter in gebiede wat in die nabyheid van primêre nodusse geleë is.

Abstract:
This study aimed to determine the status of additive manufacturing within the Gauteng province of South Africa and identify factors that are motivating or prohibiting its uptake. The existing problem is that the South African manufacturing sector has experienced poor growth resulting in a contribution of 12 percent of GDP for the year 2014 (down from 19% in 1993). The comparatively poor performance of the manufacturing sector indicates its potential fragility and that some sort of intervention may be required. Experts are anticipating the global impact of additive manufacturing to be $550 billion by 2025 and as such, this could provide a solution. However, there is little information available about the adoption of additive manufacturing within South Africa. A concurrent procedure mixed-method design intent on converging cross-sectional data was applied throughout this research. This enabled a comprehensive analysis of the possible constructs that affected the diffusion of additive manufacturing. A random-cluster sampling technique was applied which made use of a survey to sample reality. The current state was evaluated based current theories of diffusion of innovation. It was evident that diffusion of additive manufacturing is occurring within the sample cluster however, a significant shortage of accurate information and knowledge is influencing the rate of diffusion. The research also found advertising to affect respondent s view of machine cost, opinion over machine brand and machine capability however, no dominant technology was found in the within the cluster. Information obtained from the survey was compiled with existing data to produce a Bass Model for the adoption of additive manufacturing machines within South Africa. The model predicts that the market will reach its full potential by 2040 with a peak in annual grow in 2023. The report concludes with a model incorporates existing theoretical frameworks and factors that are motivating or prohibiting the adoption of additive manufacturing.

ENGLISH ABSTRACT:The historical Apartheid policy caused a lack ofinterest in metropolitan management in South Africa. Metropolitan management mainly focussed on limiting the accessibility ofthe non-white population to economic activities in urban areas. White institutions directed the intra-urban structure of urban areas to maintain their dominant economic, social and political position in the South African community. Increasing urbanization and constitutional changes in South Africa since 1991, together with international theoretical developments, necessitated a reconsideration of the nature of metropolitan management. For this purpose the objectives of metropolitan management were reformulated and industrial location was identified as an instrument in metropolitan management to increase the accessibility to economic activities. Itwas also determined that the non-establishment of industries intraditional non -white urban areas and the long distances between workplace and residential areas in North Gauteng limited the accessibility to non-whites. The New Institutional Approach, which serves as the theoretical starting point in this study, emphasises the role of rival individuals and interest groups in determining the intra-urban structure. An analysis of the role of primarily white individuals and interest groups, namely the community, the local and central governments, and the industrial entrepreneur, showed that the local and central governments played a determining role in establishing the intra-urban structure of the study area. The approach of the community and industrial entrepreneurs was mostly directed towards their own private interests and the inaccessibility of the study area for non-white population groups did not concern them. The institutions of the town councillors and officials of the local governments originated from exogenous institutions which were enforced on local governments from the central government and endogenic institutions which derived from a long tradition of urban planning. These institutions do not relate to the realities of the South African community and therefore a new institutional framework for decisionmaking on intra-urban structure was needed. Although this study only concerns one metropolitan area, the study area manifests all the characteristics of a typical Apartheid city in South Africa and the conclusions can be used in the reformulation of metropolitan management for most areas in South Africa.
AFRIKAANSE OPSOMMING: Die historiese Apartheidsbeleid het veroorsaak dat metropolitaanse bestuur in Suid- Afrika nie veel aandag gekry het nie. Metropolitaanse bestuur was grootliks gerig op die beperking van die toeganklikheid van nie-blanke bevolkingsgroepe tot ekonomiese aktiwiteite in stedelike gebiede. Blanke instellings het die intra-stedelike struktuurvan stedelike gebiede gerig om huloorheersende ekonomiese, sosiale en politieke posisie in die Suid-Afrikaanse samelewing te handhaaf. Toenemende verstedeliking en konstitusionele verandering in Suid-Afrika sedert 1991, tesame met internasionale teoretiese ontwikkelinge, het 'n herbesinning oor die aard van metropolitaanse bestuur genoodsaak. Vir doeleindes hiervan is die doelstellings van metropolitaanse bestuur herformuleer en is fabrieksvestiging as 'n instrument in metropolitaanse bestuur geïdentifiseer om die toeganklikheid tot ekonomiese aktiwiteite te verhoog. Daar is bepaal dat die gebrek aan fabrieksvestiging in die tradisionele nie-blanke stedelike gebiede en die groot afstande tussen werks- en woonplek in Noord-Gauteng toeganklikheid vir nie-blankes beperk het. Die Nuwe Institusionele Benadering, wat as 'n teoretiese vertrekpunt vir die studie dien, beklemtoon die rol van mededingende indiwidue en belangegroepe in die bepaling van die intra-stedelike struktuur. In Ontleding van die rol van hoofsaaklik blanke indiwidue en belangegroepe, nl. die gemeenskap, die plaaslike en sentrale owerhede, en die fabrieksondernemer, het getoon dat die plaaslike en sentrale owerhede 'n bepalende rol gespeel het in die vasstelling van die intra-stedelike struktuur van die studiegebied. Die gemeenskap en fabrieksondernemers se benadering was grootliks gerig op hul eie partikuliere belang en die ontoeganklikheid van die studiegebied vir nie-blanke bevolkingsgroepe was nie vir hulle ter sake nie. Die instellings van die stadsraadslede en amptenare van plaaslike owerhede het lVontstaan uit eksogene instellings wat op plaaslike owerhede vanaf die sentrale owerheid afgedwing was en endogene instellings wat uit In lang stedelike beplanningstradisie ontstaan het. Dié instellings hou nie verband met die realiteite van die Suid-Afrikaanse gemeenskap nie en daarom word Innuwe institusionele raamwerk vereis waarbinne besluitneming oor die intra-stedelike struktuur kan plaasvind. Hoewel hierdie studie slegs In gevallestudie van een metropolitaanse gebied is, openbaar die studiegebied al die eienskappe van die tipiese Apartheidstad in Suid- Afrika en die gevolgtrekkings kan gebruik word in die herformulering van die aard van metropolitaanse bestuur vir die meeste gebiede in Suid-Afrika.

Abstract:
This study is intended to unpack the current and potential future commuter transport requirements in Kagiso Township within the context of transport planning and the ongoing transformation of the transport sector in South Africa. In order to meet the above challenges, it was felt that an investigation of the socio-economic profile of transport users in Kagiso Township was required, which would be indicative of potential needs and requirements in terms of current and future travel infrastructure. This study is significant, as it considers the impact of socio-economic factors and transport interactions by fully examining the impact of accessibility, urban development patterns, local mobility and planning. Mogale City’s Kagiso Township was selected for in-depth study because it has seen one of the highest urbanization rates in Gauteng Province, with people from all over Gauteng relocating to this suburb, either buying relatively moderately priced housing via mortgaging or, alternatively, trying to gain access to government low-cost housing. The study investigates the connection between socio-economic characteristics of a local population (inter alia, age, gender, household size, and vehicles per household, employment status and income) and their transport requirements (travel demand forecasting), within an urban transport context. Socio-economic characteristics of a population are important in transport demand forecasting because there is a general belief in transport planning that the predisposition to travel and trip generation vary with the characteristics of the traveller. A travel demand forecasting model by Bussière and Rice (1999) is used for the purposes of simulating existing and future travel patterns. The forecasted household mobility and needs of commuters in Kagiso Township are compared with current municipal plans to see whether such plans are realistic and can address existing needs. The evaluation of the current municipal plans is included to test the responsiveness of public policy and practice towards the needs of the affected local community. This evaluation extracted information on whether the relevant municipality has identified the problems and issues affecting the local community of Kagiso Township. In addition, it assessed whether the municipality has identified possible solutions to these problems and issues and whether it has prioritised any projects to improve transportation in Kagiso Township.

Abstract:
Fewer than 8% of schools in South Africa have functioning libraries. There is no national policy for school libraries which compels School Governing Bodies and principals to have a library in their schools. This qualitative study, based on grounded theory, investigated ten primary schools in Gauteng that had libraries, or were in the process of setting up a library with the intention of providing a rich description of the issues and challenges facing these schools. The schools were chosen on the basis of location (Soweto and Johannesburg), and the school fees that were paid in a continuum from low/no fee paying schools to the fee paying ex Model-C schools. The resourcing of the school library, the operation of the school library and the role of the library were examined. The findings highlight the lack of a national policy, of school library posts, the theft of computers as a result of the lack of security, as well as the lack of understanding by teachers of the role the library in teaching and learning. Furthermore, there appears to be a disjuncture between the trends evident in the international literature on school libraries and what is actually happening in the primary school libraries in my study. Most significantly low/no fee paying schools with libraries were the exception and those that did have libraries were as a result of the enthusiasm and efforts of one or two individuals with the backing of the principal. Ex-Model C schools had the advantage in terms of the provision and staffing of school libraries as they had the funds to support them and, in some cases, a school librarian, provided that the principal supported the idea of a school library. In all the schools, the belief in the importance of the library regarding reading and literacy was the main motivating factor in establishing or maintaining the school library. A growing public awareness of the value of school libraries was an encouraging trend that emerged from my study.

Gale, Faith Margaret Nola. "Dropouts from literacy : an analysis of the meanings which adult learners attach to the fact of abandoning their training programme." Master's thesis, University of Cape Town, 1998. http://hdl.handle.net/11427/17245.

Abstract:
Summary in English.
When considering their dropout, many described experiences of being a misfit, or feeling uncomfortable with discourse practices in which they were expected to engage. Some had logistical difficulties in attending, such as transport or small children, but even greater than these was the fact that they had been disappointed. These learners believe the "literacy myth" that literacy, as a set of skills one can acquire, will result in significant improvements in one's life. They also equate literacy with education, and although they experience none of the benefits that are supposed to accrue to the literate, they continue to say that they believe in its power. However, in practice, attendance at adult centres is relatively poor in comparison with numbers of potential students, those termed "illiterate." It may be deduced that adult "illiterates" regard literacy as some kind of "saviour", a panacea for all ills. Even if it is not directly accessed, the fact of its existence and the notion of its power is enough to provide hope for a better future and comfort in hard times.

Abstract:
Everywhere in the world, an increasing number of entrepreneurs are becoming the pillars of economic growth and development. New venture start-ups are a vital contributing factor for any economy as well as to the tourism industry. It creates employment opportunities, involves many stakeholders and contributes to sustainable development. This exploratory research sought to investigate the barriers and constraints facing tourism entrepreneurs. It focuses on the perceptions of tourism entrepreneurs in Gauteng and Mpumalanga. Survey research was used to gather data for the study by questionnaires distributed to entrepreneurs in the Gauteng and Mpumalanga provinces. The literature study reviews the history of tourism, the role of the Government and their involvement in tourism. Other role players in tourism are also considered. The structure of tourism in South Africa, functions and initiatives of various role players as well as policy regarding tourism are discussed. The national tourism targets and size are analysed including national and international tourism forecasts. The study investigates opportunities that exist in tourism. Furthermore, it reviews concepts regarding entrepreneurship, small, medium and micro enterprises and the link between entrepreneurship and tourism. Clear problems, barriers and constraints facing tourism entrepreneurs are identified through factor analysis. The three major factors include Government policies and support, the tourism industry’s products and services and perceptions about South Africa. The item analyses that were conducted support the findings of the factor analysis. Possible limitations of the study and further areas for research are identified. Various recommendations are made to guide current and prospective tourism entrepreneurs. The research will not only be of value to entrepreneurs, small, medium and micro enterprises, but also to the tourism industry. Sustainable tourism development in South Africa can only be achieved through recognition that the Government, the public and the private sector, host communities and the natural environment are interdependent stakeholders in a complex tourism domain. No single individual, agency or group can resolve tourism issues by acting alone. The problems, barriers and constraints that tourism entrepreneurs face can only be rectified if all role players in tourism work together to reduce the impact of these problems, barriers and constraints.

Abstract:
The excavations at Sterkfontein Cave, Gauteng Province, South Africa, have yielded one of the largest collections of postcranial fossils of any hominin site. These fossils remain relatively unstudied, and few published comprehensively, despite the enormous potential of these fossils for answering questions about Australopithecus africanus paleobiology, early hominin variation, and early human evolution. This volume presents photographs, anatomical descriptions and analyses for all Sterkfontein hominin postcranial fossils that were available for study in 2009, when an international workshop of experts was convened at University of the Witwatersrand to discuss and study this material. The chapters in this volume represent a foundation for further investigations with which to interpret these and other fossils from Sterkfontein, and from all over Africa, that will be recovered in years to come.

Abstract:
Maringe ought to be commended for putting together an invaluable contribution to our understanding of research into a complex education system in South Africa. This volume provides a useful foundation to the current state of education quality in South Africa including the impact of interventions. It also brings to the fore challenges still facing education transformation. The evidence presented which, taken together, lays out a coherent view of how improvements could be made. Albert Chanee Head of Planning, Gauteng Department of Education For too long the weight of educational scholarship produced in South Africa has been limited to that simple and standard form called the literature review. Now, for the first time, education researchers are provided with an African-based text on the concepts and methods of conducting systematic reviews. In this exceptional work of editorship, Felix Maringe brings together some of the leading researchers on South African education to model and demonstrate how to review a significant body of research on a chosen topic which is adjudicated strictly on the basis of the quality and efficacy of the evidence in hand. I have no doubt that this remarkable book will become a standard reference for educational researchers in and beyond the African continent. It will also lift the quality of educational inquiry by equipping a new generation of scholars with the capacity for doing evidence-based research that compels the attention of policymakers, planners and practitioners alike.
