We present our process for the development and analysis of a multilingual names corpus, called Multipron-split. It is derived from Multipron, a corpus collected in previous work [1], where names and speakers were drawn from four South African languages, namely Afrikaans, English, isiZulu and Sesotho. The new corpus is more suited for multilingual pronunciation modelling and research as the “words” consist of either a name or surname, rather than a combination of the two. This enables us to model pronunciations from a single language of origin, which has previously been shown to be important in pronunciation modelling for proper names. An algorithm is presented through which the most common pronunciations of names, also called reference pronunciations, can be automatically extracted from the observed pronunciations. We show that the most common pronunciation variants correlate well with the different speaker languages, and that systematic phone substitutions occur when speakers of one language pronounce names from a different language. Also, reasonably accurate automatic pronunciations can be generated with an automatic grapheme-to-phoneme converter, especially when the speaker language agrees with the name language

This paper explores and describes how teacher-students from rural communities in the Eastern Cape, South Africa, enrolled for a BEd Honours programme, experienced social media support to assist and guide them to compile an individual research proposal. Kruger’s (2012) conceptual framework addressed issues relating to 21st century learning skills of supporting teacher-students in an open distance learning environment. The researchers compiled a support group, FaceFunda on Facebook, according to the metaphor of a taxi—a well-known object to the participants—in order to enhance their learning experience while they interacted supportively with one another and the facilitator towards compiling their research proposals. None of the participants had previously used Facebook and they experienced many challenges. A constant comparative qualitative methodology analysed the integrated dataset and three themes emerged. Recommendations to the Unit of Open Distance learning related to four support aspects to foster social media literacy of rural teacher-students.

There is a growing consensus on the potential for information and communications technologies (ICTs) to support socio-economic development in sub-Saharan Africa (SSA). Universities as providers of higher education are critical to developing SSA countries by, amongst others, empowering the region to develop appropriate ICT solutions for local challenges. The purpose of this paper is to describe and discuss how contextual realities influence the development of ICT programme curricula at public universities in South Africa, a developing country in SSA, in order to meet the demand for ICT skills. After a brief discussion of the factors that influence the content and delivery in education systems an overview of the South African public higher education context is provided. Against this background the content and delivery of ICT programme offerings and the rationale behind the programmes at four South African public universities are presented in case study format and concludes with a discussion of the case studies. The paper may be of value to academic departments as examples of how other departments are responding and adjusting their offerings, to government departments and policy makers by engendering a better understanding of the impact of policy on programme development and to industry by illustrating the diverse stakeholders in higher education and academia’s responsiveness to these diverse requirements.

Research using voice-based services as a technology platform for providing information access and services within developing world regions has shown much promise. The results for design and deployment of such voice-based services have varied depending on the application domain, user community and context. In this paper the authors describe their work on developing a voice-based service for obtaining feedback from school children, a previously unexplored user community. Through a user study, focus group discussions and observations of learners’ interaction with multiple design prototype versions, they investigated several factors around input modality preference, language preference, performance and overall user experience. Whilst no significant differences were observed for performance across the prototypes, there were strong preferences for speech (input modality) and English (language). Focus group discussions revealed rich information on learner’s perceptions around trust, confidentiality and general system usage. They highlight several design changes made and provide further recommendations on designing for this user community.

IEEE/ACM International Conference on Advances in Social Networks Analysis and Mining (ASONAM)
In this study, a Central Composite Face Centered (CCF) design was employed to study the individual and interaction effects of demographic characteristics on the spread of HIV in South Africa. The demographic characteristics studied for each pregnant mother attending an antenatal clinic in South Africa, were mother's age, partner's age, mother's level of education and parity. HIV status of an antenatal clinic attendee was found to be highly sensitive to changes in pregnant woman's age and partner's age, using the 2007 South African annual antenatal HIV and syphilis seroprevalence data. Individually the pregnant woman's level of education and parity had no significant effect on the HIV status. However, the latter two demographic characteristics exhibited significant effects on the HIV status of antenatal clinic attendees in two way interactions with other demographic characteristics. Using HIV as the optimization objective, the following summary statistics were obtained, R2 = 0.99 and two-factor interactions (2FI) model F-value of 63.77. The model F-value of 63.77 implied the 2FI model was significant and there was only a 0.01% chance this model value could occur due to noise. The model 'Lack of Fit' value of 0.01 implied that the 'Lack of Fit' was not significant relative to the pure error and thus there was a 99.88% chance that this 'Lack of Fit' F-value could occur due to noise. An adeq. precision value of 25 was obtained, suggesting that this 2FI model could be used to navigate the design space. A 3D response surface plot indicated that the highest rate of HIV positive individuals was obtainable at the highest age of the pregnant women and lowest age of their partners.

Focused intervention study and the promotion of effective oversight: experiences from the Gauteng Provincial Legislature

Gauteng Provincial Legislature
This aim of this paper is to analyse the experiences of the Gauteng Provincial Legislature (GPL) and its Focused Intervention Study (FIS) to demonstrate that oversight could be effective in serving public interests if it is held as a continuous process, rather than fragmentary once-off event. In the interests of financial accountability and compliance as well as enhancing service delivery performance, Section 114(2)(b) of the Republic of South Africa’s 1996 Constitution accords the legislature the role of overseeing the activities of government departments and other organs of state. Notwithstanding this constitutional mandate for the South African legislative branch of government, threats to democracy have been incessant, characterized by maladministration and misuse of public funds, among others, which in return precipitates suboptimal service delivery performance, The measure of effective oversight is in its service of the interests of the public, especially that which involves the delivery of services. However, the South African legislature’s oversight role is characteristically reactive and, therefore, incapable of proactively dealing with emerging challenges, opportunities and emergencies. This paper argues that oversight can be effective if it is conducted as an on-going process before, during and after the implementation of programmes.

The need to provide agricultural information for improving agro products market information has led to emergence of numerous ICT-based projects in developing country. These projects aim at promoting commercialization of smallholder agriculture products and subsequently their welfare. This research project examines the welfare effects of the use of ICT for marketing of agro-products in Costal regions of Tanzania. It encourages the applications of websites designing and access to the internet as alternative to increasing market access to the Agro products. The study finds that farmers that use ICT-based market information are more noticeable and have better access to market services than their counterpart. It also discusses challenges and opportunity of technologies in particular ICT applications to the agriculture.

This paper explores how Critical Systems Thinking and Action Research can be used to improve student performance in Networking. When describing a system from a systems thinking perspective, the following aspects can be identified: the total system performance, the systems environment, the resources, the components and the management of the system. Following the history of system thinking we observe three emerged methodologies namely, hard systems, soft systems, and critical systems. This paper uses Critical Systems Thinking (CST) which describes systems in terms of contradictions and conflict. It demonstrates how CST can be used in an Action Research (AR) project to improve the performance of students. Intervention in terms of student assessment is discussed and the impact of the intervention is discussed.

Students with high level skills are in demand, especially in scare skill environments. If universities wish to be successful and competitive, its students need to be adequately equipped with the necessary tools. Work Integrated Learning (WIL) is an essential component of the education of a student. The relevance of higher education should be assessed in terms of how it meets the needs of society and the world of work in a global economy. This paper demonstrates how to use Habermas's theory of communicative action to reflect on students- perceptions on their integration in the work environment to achieve social integration and financial justification. Interpretive questionnaires are used to determine the students- view of how they are integrated into society, and contributing to the economy. This paper explores the use of Habermas-s theory of communicative action to give theoretical and methodological guidance for the practice of social findings obtained in this inquiry.

21021287 - Barnard, Etienne
This paper introduces a model of affect to improve prosody in text-to-speech synthesis. It operates on the discourse level of text to predict the underlying linguistic factors that contribute towards emotional appraisal, rather than any particular surface emotion itself. The architecture of the model is described and its performance is evaluated on three levels—its predictive accuracy on text, its effect on natural speech and its effect on synthesised speech.

This research paper aims to gain a better understanding on the concepts of Human-computer interaction (HCI) in general and the application of HCI principles in this field. This paper also aims to gain a better understanding of electronic registration systems (e-registration systems) and the use of web forms for this purpose. By conducting this research, this paper identifies which HCI principles could be applied to the design of a web form for e-registration derived from its paper-based registration form. An example referred to in this paper is the paper-based registration form for individual tax registration.

The dramatic effect of information technology on society is undeniable. In education, it is evident in the use of terms like active learning, blended learning, electronic learning and mobile learning (ubiquitous learning). This study explores the perceptions of 54 learners in a higher education institution regarding the use of mobile devices in a third year module. Using semi-structured interviews, it was found that mobile devices had a positive impact on learner motivation, engagement and enjoyment. It also improved the consistency of learning material, and the convenience and flexibility (anywhere, anytime) of learning. User-interface limitation, bandwidth and cognitive overload, however, were of concern. The use of cloud based resources like Youtube and Google Docs, through mobile devices, positively influenced learner perceptions, making them prosumers (both consumers and producers) of education content.

A complete intonation model based on quantitative target approximation is described for Yorùbá text-to-speech (TTS) synthesis. This model is evaluated analytically and perceptually and compared to a fundamental frequency (F0) model using the standard HTS implementation. Analytical results suggest that the proposed approach more efficiently models F0 contours given typical data constraints in under-resourced environments and perceptual results comparing the proposed model with HTS are encouraging.

Food security is defined as a state in which all people in a household at all times have both physical and economic access to sufficient food to meet their dietary needs for a productive and healthy life. Household food insecurity has been associated in the last decade with several negative health and nutrition outcomes, and South Africa in this regard was no exception. The question however arises: To what extent are low income households vulnerable to food insecurity? This study analysed food security status of households, and analyse the self- reported vulnerability with regard to food security of these households. A quantitative research method was deployed and a stratified random sample of 295 questionnaires was administered in the township of Bophelong, a low income neighbourhood in Southern Gauteng, South Africa. Following the Household Food Insecurity Access Scale, households were asked to describe behaviors and attitudes that relate to food insecurity, also called domains of the food insecurity experience. The study showed a high incidence of vulnerability towards food insecurity amongst households in this low income neighborhood. Research indicated that urban food insecurity is a considerable challenge and that food insecure urban households may be more vulnerable to deeper food insecurity than their rural counterparts. This indicates that the drivers and maybe consequences of food insecurity in urban areas may require different conceptual framings and policy responses from policy makers. This paper therefore suggests the development of an explicitly urban food policy, to lower the vulnerability of food insecure households in urban settings.

The South African Socially Responsible Investment (SRI) Index was launched in 2004 in order to encourage JSE listed companies to comply with issues of environmental, economic and social sustainability. This study analysed the effect of private consumption, employment growth rate, government expenditure, gross domestic investment, import and exports on the SRI Index. Using a co-integration test, error correction model and Granger causality test, the study found a joint long run effect of these macroeconomic variables on the SRI Index. It was only private consumption which had a significant short-run effect on the SRI Index. In general, there was a two way causal relationship between the SRI Index and the selected macroeconomic variables. This study concluded that Sustainable SRIs play an important role in the development of the South African economy.

A critical systems perspective on research methodology for research in e-learning in information systems classes

Critical systems thinking

Information systems education
E-learning
The aim of this paper is to provide a critical systems thinking perspective on e-learning research in information systems classrooms. Many higher education practitioners are under pressure from their institutions to do research and to publish their findings. Higher education institutions spend large amounts of money on freeing up lecturers’ time for research by incorporating better technology in teaching. Many also believe that the so called generation-Y students can learn only when they are using technology. This leads to three problems: firstly, the class-room becomes a research centre; secondly, average quality research papers are written; and thirdly, technology drives teaching practices and not the other way round. Although these are often viewed as three independent problems they can be addressed as symptoms of one single problem: We struggle to find a method to reflect on and design our teaching practices in a way that truly benefits our students, the information technology industry and the scholarly community we are part of. Overall the motivation for teaching and the motivation for research about teaching become blurred and move away from most lecturers’ original motivation for entering academia. This paper uses critical systems thinking to motivate critical social theory as an appropriate research paradigm and action research as research methodology for research projects in e-learning in information systems classrooms. It reflects on teaching of information systems and using e-learning from a critical systems perspective. Doing research in e-learning in an information systems classroom is viewed as a pluralist complex problem with some coercive characteristics according to the Flood and Jackson categorisation. Critical social heuristics is used to better understand the different worldviews and associated objectives in the problem situation. Action research is viewed from the perspective of critical social research therefore the guidelines for critical social research in information systems developed by Myers and Klein are applicable. Key to such an application of action research is the use of a critical theoretical framework or theory to guide intervention as illustrated by the depiction of action research of Peter Checkland. This paper explores suitable educational theories to guide intervention in information systems classrooms what will be beneficial to different groups of interest as identified in the application of critical social heuristics. It aims to address the problems stated above by providing guidelines for good research in the e-learning discipline.

Resource-scarce
We present progress towards automated Lecture Transcription (LT) in resource scarce environments. Our development has focused on the transcription of lectures in Afrikaans from two faculties at North-West University. A bootstrapping procedure is followed to filter and select well-aligned segments of speech. These segments are then used to train acoustic models. Initial work towards language modeling for LT in a resource-scarce environment is also presented; manual lecture transcriptions are combined with text mined from other sources such as study guides to train language models. Interpolation results indicate that study guides are a useful resource for language modeling, whereas general text (obtained from a publisher of Afrikaans books) is less useful in this context. Our findings are confirmed by the reduced word error rates (WERs) obtained from our off-line speech-recognition system for Lecture Transcription.

Design of an e-Registration Prototype Using HCI Principles: With Specific Reference to Tax Registration
Terblanche, Juanita T.
20398999 - Terblanche, Juanita T.
This paper introduces an initial web form prototype for first-time taxpayer registration in South Africa. At present no online tax registration system is currently available. The researcher would like to stress the fact that the initial web form design and application of the chosen HCI principles are limited to interface design. The purpose of the study is to evaluate whether a web form will allow for efficient interaction and good user experiences when appropriate HCI principles are applied to the design. The web form for first-time taxpayer registrations is merely an example of how HCI principles may be applied to an electronic registration system. The researcher in no way suggests this web form and the suggested processes to be followed as a complete and final solution or alternate option to the paper-based form process.

Proceedings of the 8th International conference on e-Learning (ICEL 2013), Cape Town, South Africa, 27-28 June, 2013
This paper investigates the extent to which the Scratch programming language has been accepted as an electronic teaching tool among teachers in South Africa. Information Technology (IT) was identified as a scarce skill in the Birchwood Declaration (2007) released by the South African Department of Education, a problem compounded by the declining number of the students who enrol in IT-subjects at school. Scratch was introduced as an e-Learning tool in the IT curriculum as part of an effort to address this issue (NCS 2012). Through the use of this tool, learners can be taught basic programming principles in a visual and interactive way. Although several studies on Scratch as a programming teaching tool have been conducted in other countries, such as the United States of America, the aim of this study is to determine how teachers in South Africa perceive the use of Scratch as a teaching tool during the first year of implementation. A mixed-method research approach, utilising both qualitative and quantitative re-search methods, was selected. The findings show a definite change in the attitude of teachers towards Scratch as an e-Learning tool, from initial scepticism to a more positive attitude later on in the year. However, some concerns were raised which should be noted and addressed in order to ensure that this tool adds value to the teaching and learning experience in class. The findings of this study could pave the way for the implementation of Scratch at first-year level, particularly as an introduction to programming courses. This could serve to bridge the gap between the schooling system and university in terms of the development of critical thinking-skills.

Strategic management
Labour unions
Job satisfaction
South African Broadcasting Corporation
The relationship between strategic management and labour unions has proven to be significant towards organisational productivity. This relationship has the power of influencing the employees positively or negatively depending on its nature. For this reason, Labour Relations Acts are instumental in shaping the relationship between strategic management, labour unions and employees. On their part, labour unions form an integral part in the employment sphere and towards the goal of achieving equality and democratization in the workplace. The basic function of Labour Unions is to represent members in the workplace by advancing their interests through collective bargaining and strategic management processes in order to maintain good industrial relations and to promote efficiency. Ineffective collective bargaining due to lack of good faith affects organisational productivity, employee morale and trust in labour union leaders. The paper examines these ideas within the South African Broadcasting Corporation (SABC) to determine the extent of the relationship between strategic management and labour unions as well as its role in organisational productivity. It holds that strategic management tools reduce employee strike action and increase job satisfaction. the paper recommends that measures be devised to strengthen strategic management and labour unions in order to enhance organisational productivity at the SABC, specifically, and in such other public sector organizations, in general.

Global Business and Technology Association Fifteenth Annual International Conference (GBATA), Helsinki, Finland, 2-6 July 2013
Logically, financially-educated individuals should make better financial decisions for their families, increasing their economic security and well-being. The purpose of this study was to explore the financial planning and personal financial management of South African professional soccer players. In the process, a variety of issues were investigated. The research focused on the following important question: Why is financial literacy important particularly for soccer players who experience short-lived soccer careers. A quantitative research design involving the administration of a two-section questionnaire was adopted for the study. It was concluded that most professional soccer players plan poorly for their future because of a lack of financial literacy which results in them not being adequately prepared for the transition into retirement. Recommendations on the findings were made and the implications for future research outlined.

Frontiers in Education Conference (FIE), Oklahoma, USA, 23-26 October 2013
Systems Analysis and Design (SAD) is a second-year subject offered within the Information Technology (IT) course at the Vaal Triangle Campus of the North-West University in South Africa. The diverse environment of this campus includes students representing most ethnic groups in South Africa, adding to the complexity of classroom interaction. This is further complicated by the fact that students find the subject difficult, mostly because it includes many new concepts used in different contexts. SAD students also grapple with fuzzy issues such as fact-finding from system users and representing information obtained from models that are designed for feedback. SAD is therefore far removed from the more exact subjects like programming and mathematics that many IT students excel in. Videos explaining difficult SAD concepts were produced and made available to students on a Learning Management System (LMS). The students were motivated to come to classes prepared. During the first semester concepts were explained during formal class times. Formal explanations were not given during the second semester because students were expected to build on the knowledge that they had gained during the first semester. The students were also required to make use of all the resources available to them to come to class prepared. Group work was done in class during both semesters. The success of implementing reverse instruction in the second semester is evaluated through an interpretive lens. The fifteen modal aspects developed by the philosopher Herman Dooyeweerd were used to ensure a clearer picture of the researched situation was painted with a view on diversity and unexpected usage.

Systems Analysis and Design is a key subject in Information Technology courses, but students do not find it easy to cope with, since it is not “precise" like programming and not exact like Mathematics. It is a subject working with many concepts, modeling ideas into visual representations and then translating the pictures into a real life system. To complicate matters users who are not necessarily familiar with computers need to give their inputs to ensure that they get the system the need. Systems Analysis and Design also covers two fields, namely Analysis, focusing on the analysis of the existing system and Design, focusing on the design of the new system. To be able to test the analysis and design of a system, it is necessary to develop a system or at least a prototype of the system to test the validity of the analysis and design. The skills necessary in each aspect differs vastly. Project Management Skills, Database Knowledge and Object Oriented Principles are all necessary. In the context of a developing country where students enter tertiary education underprepared and the digital divide is alive and well, students need to be motivated to learn the necessary skills, get an opportunity to test it in a “live" but protected environment – within the framework of a university. The purpose of this article is to improve the learning experience in Systems Analysis and Design through reviewing the underlying teaching principles used, the teaching tools implemented, the observations made and the reflections that will influence future developments in Systems Analysis and Design. Action research principles allows the focus to be on a few problematic aspects during a particular semester.

World Academy of Science, Engineering and Technology 64, Paris, France, 28-29 November 2012
Information systems practitioners are frequently required to master new technology, often without the aid of formal training. They require the skill to manage their own learning and, when this skill is developed in their formal training, their adaptability to new technology may be improved. Self- directed learning is the ability of the learner to manage his or her own learning experience with some guidance from a facilitator. Self-directed learning skills are best improved when practiced. This paper reflects on a critical social research project to improve the self-directed learning skills of fourth year Information Systems students. Critical social research differs from other research paradigms in that the researcher is viewed as the agent of change to achieve the desired outcome in the problem situation.

“No more going to Nandos”: Rudimentary statistics and venal public servants in tender adjudication

Corruption
Anti-corruption
Public service
Tender adjudication
Insider trading
This paper advances the notion that corruption in public service is perpetrated by the corruptibility of functionaries. The psychopathology of corruption demonstrates that hominids are inherently venal and will thus continually reconnoitre ways of extracting personal wealth from the state. While castigatory actions and detection systems are a deterrent, they have proven to assist in as far as bureaucrats master the systems. In time, though, public functionaries device devious strategies to navigate away from detection., It is against this background that this paper postulates that measures for eliminating the human factor and potential for insider trading rom supplier selection could provide for self-checking that would curb fraudulent award of tenders. This hypothesis is tested through statistical summaries such as standard deviation for the determination of the most responsive tenderer in terms of price. Such measures could render it impossible for the adjudicator to pre-empt the most responsive tenderer and thus eliminate insider trading.

In an Information Technology course, learners are expected to learn about the use of technology. They need to be able to program, do mathematics and statistics, and should also have other technical subjects. Although learners sometimes struggle with the logical thinking necessary for becoming a good programmer, the ones who grasp programming easily, tend to struggle with the different approach necessary for a subject like Systems Analysis and Design (SAD). Learners are confronted with overwhelming amount of theoretical material that is often repeated in different contexts – something which confuses them. They are also sometimes overwhelmed by the use of a textbook which covers extensive material. Bearing this in mind, this study sought to use Social Networking Sites (SNS) and Instant Messaging (IM) to assist students in preparing for their examination. Interpretive research is used to qualitatively analyse the communication between the lecturer and students and also among the students themselves. Along with the identification of themes in this communication, the fifteen modal aspects introduced by the Dutch philosopher, Herman Dooyeweerd, are used to analyse and understand the use and value of mobile technology in an educational context.

Proceedings of World Business and Social Science Research Conference, Bangkok, Thailand, 24-25 October 2013
The origins of social security in South Africa can be traced back to attempts by the previous apartheid government to create a welfare state for whites during the apartheid era. Since the first democratic election in South Africa in 1994, the total number of social security system beneficiaries increased from 2.4 million in 1998 to 12.4 million in 2008. Recent research has confirmed that the various social grants are well targeted at the poor and that they have a significant impact on poverty. However, the question arises: To what extent does the social security system ensure food security for households in poorer areas? This study analysed food security of households receiving government grants. A quantitative research method was deployed, and a stratified random sample of 295 questionnaires was administered in the township of Bophelong, a low-income neighbourhood in southern Gauteng, South Africa. Using the Household Food Insecurity Access Scale, households were classified into food secure and insecure. The total amount of social grants received per household, household size, and the age of the household head were found to exert a strong positive impact on food security. Conclusions include whether households who receive social grants, differ significantly from households who do not receive social grants, in terms of food security.

Valuing the impact of pollution on the poor: the case of Bophelong
Grobler, W.C.J.

Global Business and Technology Association Fifteenth Annual International Conference, Helsinki, Finland, 2-6 July 2013
This paper reports on a comparative study of poverty and the social cost of pollution among poor households in Bophelong. The level of poverty was measured and compared with the cost of pollution as revealed by citizens of Bophelong through a household questionnaire. To do this, the level of poverty was determined by looking at the Household Subsistence Level (HSL), while the social cost of pollution was determined using Contingent Valuation methods. These methods are generally termed contingent valuation (CV) methods and are used to elicit from respondents what they would be willing to pay for a cleaner environment or what they would have to be paid to accept the pollution. Further, the study performed regression analysis to determine the effect of pollution on poverty levels. Pollution was found to be a problem in the area as reported by respondents. Respondents valued pollution higher in 2013 compared to 2003. It is important for policy makers to be aware of the cost of pollution to the poor as they are more vulnerable due to the inability to cushion themselves against any negative consequences.

IST-Africa Conferences Proceedings, Nairobi, Kenya, 29-31 May 2013
Providing good medical care in low-resourced areas is a challenge faced by many low and middle income countries. Continuously improving mobile communication infrastructure in these areas is however providing the opportunity to improve the access to medical information using mobile phones in these areas. In particular, physicians and community health workers based in low-resourced areas could be the first to gain benefit from this technology. This paper considers the implementation of a medical information search engine accessed on mobile devices for low-resourced areas. The challenges faced in low-resourced areas are covered, and adaptation of mobile medical information search for these areas is discussed. Finally, the impact that this technology can have in low-resourced areas is presented.

Global Business and Technology Association Fifteenth Annual International Conference (GBATA), Helsinki, Finland, 2-6 July 2013
Mega sporting events need a number of activities to be properly coordinated if they are to be successful. These events require large numbers of human resources and invariably reliance is heavily on volunteers. Essentially, volunteers form the backbone in accomplishing the mega event logistics. Despite the foregoing, little research has characterized volunteers in sporting mega events from a South African perspective. This study addressed this issue by establishing university students’ important motivational factors in terms of gender and gender with respect to age. To collect data, the 40-item Motivational Factors in Sport Volunteering Scale was used. In all 425 participants with ages ranging between 18 years and 25 years, responded fully to the administered instrument. Results indicated that similar numbers of females and males reflected the same motives for volunteering. This finding was replicated in terms of gender and age. A significant contribution of this study was the fact that it provides event managers with a better understanding with regards to who to attract, place and retain for mega sporting event volunteers.

Proceedings of the IADIS international conference on ICT, society and human beings 2013 and IADIS International Conference e-Commerce 2013, Prague, Czech Republic, 22-26 July 2013
Information and communication technology (ICT) is essential to the operation of business, and create many employment opportunities. High volumes of students graduate in ICT however students struggle to find job placement. To address the need for ICT skills, universities must create programs that meet the demands of a changing ICT industry. This requires a partnership between industry, universities and other stakeholders. The researchers explore a work integrated learning (WIL) approach where practical and theoretical knowledge are united and linked to industry needs. This paper explores the applicability and suitability of the work of Maslow and Dooyeweerd respectively to foster a holistic understanding of the student and his/her situation. The above methods provide tools for understanding softer issues beyond the technical skills required. This paper uses the Maslow hierarchy of needs and the aspectual analysis of Dooyeweerd to reflect on the total being of students registered for ICT WIL at Vaal University of Technology in South Africa. The study’s findings suggest that besides skills requirements, a deeper understanding and empowering students from being a student to a professional need to be understood and addressed.

The paper evaluates the local government processes developed for ensuring the authenticity of educational credentials in the Sedibeng District Municipality. Verification of academic credentials forms part of the internal control in a legitimate institution. The paper finds that academic fraud is on the increase across the world, developing and developing countries alike, and it is a threat to the intellectual integrity on which the advancement of knowledge depends. globally, a set of laws and regulations have been established to tackle the rise in fake qualifications. However, such measures are inadequate and unreliable, and perpetrators are often detected after a significant number of years. The paper points out that advances in technological communication have facilitated the growth of academic fraud by electronic means. As a result it drives the public sector recruitment process making it impracticable for recruitment officers to closely inspect individual applications in detail. the paper observes that support staff posed minor risks compared to senior and middle managers, which is a costly threat to societies, to their efficient operation and to public trust in the reliability and security of their institutions. The paper calls for a system that would mitigate the risk of educational fraud often experienced in the public sector. It suggests that means be devised to adopt responsive and enhanced efficient processes for dealing with breaches of integrity.

The effect of ten years on the capacity component of the Water Poverty Index
Van der Vyver, Charles
12264814 - Van der Vyver, Charles
22nd IBIMA Conference, Rome, Italy, 13-14 November 2013
Water management has been carried out for many centuries wherever there has been a need to provide water to large numbers of people. Complex social norms have developed around water management and competing users have established political (governance) and economic cooperative relationships. Water resources will steadily decline because of population growth, pollution and expected climate change (Hemson et al., 2008). It has been estimated that the global demand for water doubles approximately every two decades (Meyer, 2007) and that water will even become as expensive as oil in the future (Holland, 2005). “In the year 2000, global water use was twice as high as it was in 1960” (Clarke and King, 2004:19). Unfortunately this trend is expected to continue. The aim of this research is to identify whether efforts that were made to improve the capacity component of the water poverty index (WPI) in a region have been successful. It builds on a previous study on a region in Southern Gauteng and the Northern Free State provinces of South Africa, and utilizes the latest Census data to draw a comparison. In the 10 year period from 2001 to 2011 the capacity component of the WPI in the region increased by roughly 15%, which was caused by a significant increase in the educational part of the component. The research concludes that interventions made to increase the educational level of the regions residents have been successful, and that future research should focus on continuously analysing the results of interventions involved in the WPI, thereby ensuring their effectiveness.

This paper contends that the new “Africa Rising Narrative” will net lead to the majority of African citizens attaining prosperity under the current democratic transition. this paper argues that Africa lacks appropriate Pan-Africanist theorization for the African development agenda if the continent were to attain socio-economic prosperity. South African and Nigerian democratic transitions and economic development policy experiences in the late 1990s and 2000 affirm the observation of this paper. to this extent, this paper asserts that the notion that Africa is the future centre of commerce and development is not founded on appropriate theorization of the relationship between democratization and economic policy.

This paper examines the norms and standards for using municipal resources. Managing resources forms part of internal procedures. the paper specifically analysis the strategies implemented for upholding municipal employees when using land line telephones the element of communication and information devices and services resources. Many of the local government related matters often address the blatant criminal acts such as theft, bribes, fraud in various forms and manipulation of tendering processes. This study found that misuse of communication and information devices and services resources may seem to be more subtle in nature. Yet, a municipal council remains vulnerable to resource misuse which often leads to significant direct loss to councils and gains to individuals and corporate bodies. Such conduct is unacceptable as it deprives the community whilst paying too much for the quantum and quality of services it is receiving. In this paper the author set out to do three things: the economic impact of resources misuse; the assess the policies; procedures and information and compliance mechanism instigated in regard to resource misuse; and seeks to recommend the methods that can be applied to curtail the dilemmas often encountered by municipal councils. The outcomes of this paper is realised by means of a qualitative analysis and is supported by interviews and a visit to the City of Johannesburg Metropolitan Municipality.

Global Business and Technology Association Fifteenth Annual International Conference (GBATA), Helsinki, Finland, 2-6 July 2013
This study analyzed the prevalence of household food poverty in a township of Kwakwatsi, South Africa. A household was defined to be in food poverty when its monthly food spending is less than the cost of a basic food basket. A proxy food poverty line was used a measure of food poverty in the area. It was found that about 68 per cent of the sampled households are in food poverty. Higher food poverty rates were found with increasing household sizes, lower educational attainment of the household head and increasing age of the head of household. The results of this study are at household level and provide reference to the types of households likely to be living in food poverty.

We present methods for modelling and synthesising fundamental frequency (F0) contours suitable for application in text-to-speech (TTS) synthesis of Yorùbá (an African tone language). These methods are discussed and compared with a baseline approach using the HMM-based speech synthesis system HTS. Evaluation is done by comparing ten-fold cross validation squared errors on a small corpus of four speakers. We show that the proposed methods are relatively effective at modelling and generating F0 contours in this context, achieving lower error rates than the baseline. These results suggest that our methods will be useful for the generation of improved synthesis
of tone in African languages, which has been a challenge to date.

IST-Africa 2013 Conference Proceedings, Nairobi, Kenya, 29-31 May 2013
Access to information and communication is one of the most important needs in any population group. It is generally challenging for people in the developing world to access information because the tools and the technologies used to access information are prohibitively expensive and also require training prior to operating such tools [13]. This restrains those who are either poor, illiterate, or without computer skills from accessing information. We carried out two case studies of contrasting Interactive Voice Response (IVR) systems. The research compared the users' choice of interaction modality between Dual-Tone Multi-Frequency (DTMF) and speech-enabled IVR modalities and correlated the results with learnability of the different modalities in the milieu of the two systems. The targeted users are oral users of Southern Africa with diverse literacy levels but nevertheless numerically literate and accustomed to the telephone.

Basden’s Human Usage of Computers (HUC)
Proceedings of the 14th Annual Conference on World Wide Web applications (WWW), Durban, South Africa, 7-9 November 2012
In an Information Technology course, learners are confronted with learning about technology; programming, other technical subjects and some mathematics and statistics. Although learners can struggle with the logical thinking necessary for becoming good programmers, the ones who are grasping programming easily, struggle with the different type of rigour necessary in a subject like Systems Analysis and Design (SAD). Learners are confronted with theoretical material overwhelming in quantity and repeating in different contexts – confusing them. Also, a substantial part of the subject should be the practical implementation of a real-life system. Addressing the overwhelming material, the use of Social Networking Sites (SNS) to deliver definitions and explanations to learners, ensuring easy access to material, have been introduced in conjunction with two functions in the learning managing system already used by the learners, namely forums and the glossary. During the first semester the material is new and the focus is on becoming comfortable with it, while in the second semester the focus moves to applying the material in a practical environment. At the end of the semester this initiative was followed up with an action to support students’ in their examination preparation. Since the learners in SAD are mostly from disadvantaged communities, it was important to introduce tools that are readily available to the learners, assistants and the teacher. Three SNS were selected to accomplish this; WhatsApp, MXit and BlackBerry Messenger (BBM). This article uses the fifteen modal aspects introduced by the Dutch philosopher, Herman Dooyeweerd and refined by Basden, along with the Human Usage of Computers (HUC) Framework developed by Basden, focusing on Engaging with Meaningful Content (EMC) to analise the use of the SNS computer technology. Recommendations forthcoming from this project will be used to guide the second SAD semester, as well as future first semesters.

Global Business and Technology Association Fifteenth Annual International Conference (GBATA), Helsinki, Finland, 2-6 July 2013
The paper presents the results of research carried out to examine mobile phone addiction among students at a South African University. The results suggest that students exhibited addiction tendencies. Of the top sources of addiction were; a feeling of loss when students did not have their mobile phones with them, reduction in sleep patterns, use of mobile phones longer than intended, feeling of restlessness and irritability when not using mobile phone and use of mobile phones to escape from problems. Two main addictive symptoms were extracted and students’ behaviour were categorised as ranging from loss of control to withdrawal.

The purpose of this paper is to report on the results of a pilot study conducted on the determinants and inhibitors of Generation Y students’ attitudes towards Facebook advertising. The findings suggest that Generation Y students have a positive attitude towards the information value, entertainment value, credibility, self-brand congruity of advertising on Facebook and attitude towards the social interaction value of Facebook. Their attitudes towards trust in the site and trust in the members while positive, was not significant. Results suggests that Generation Y students have negative attitude towards the invasiveness of advertisements placed on Facebook and a negative, but not significant, attitude to the time cost involved in participating on Facebook.

Proceedings of the 21st International Business Information Management Association Conference (IBIMA 2013), Vienna, Austria, 27-28 2013
The aim of this research is to quantify the difference in the water poverty index when calculated with the additive function compared to the multiplicative function. It is calculated and compared for the three towns that together form the Vaal Triangle region in South Africa. A case study is performed with data that was collected at the household level, all of which is at a high assurance level. Although many functions are available for the calculation of composite indices, the study finds that although the multiplicative function produced lower overall values, the final recommendation regarding which town is most in need of an intervention would have been unchanged. It concludes that the scale at which the data is gathered, the chosen components, and the data sources could all influence these results, and that the function comparisons are critical in ensuring the relevance of the chosen function. Future research should focus on refining the available functions, as well as on documenting the best functions for different scenarios

This paper is derived from a completed Master’s study where the objective of the research was to design an electronic registration (e-registration) web form prototype (translated from its paper-based registration form) by using appropriate HCI principles to promote good usability. The aforementioned prototype was tested, evaluated and redesigned according to the findings. This paper discusses the research process followed to conduct said research. During the researcher’s investigation into research methodologies it was clear that the design and creation of a new web form artifact to be used for electronic registration falls within the context of Design Science and this paper aims to explain why.

21021287 - Barnard, Etienne
The purpose of this paper is to address the challenges and describe step-by-step solutions faced when developing an automatic speech recognition system in multilingual societies. We give a brief statistical analysis of the data that have been harvested from the internet. The harvesting process operates in a multilingual environment where code-switching is the norm. We specifically focus our attention on the challenge of number normalization, pronunciation and the variations associated with
it. We then develop various systems to illustrate the effects of different approaches to modelling the pronunciation of numbers.

Talent development in sport is a complex process involving the interaction of multidisciplinary aspects that directly and/or indirectly affect athletic progression and performance. The purpose of this study was to identify factors that contribute to a long term talent development focus so that the success of university athletes in South Africa is increased. Athletes over the age of eighteen years, who qualified to compete under the auspices of University Sport South Africa, were requested to complete the Talent Development Environment Questionnaire for Sport (TDEQ). Included in the questionnaire were twenty four items specifically measuring the extent to which athletes are exposed to development opportunities designed to form foundations for long term success rather than preparation for short-term results-driven outcomes. The results of the study revealed that five factors influenced the advancement of a long-term talent development focus which included the following: training support, coach guidance, skills development focus, work ethic and training goals. These factors are highly predisposed by the coach. Subsequently an implicit need for a theoretical model of effective sport coaching practice would be highly beneficial in providing coaches with the necessary knowledge required to provide a conducive developmental environment for athletes.

The pursuit of African continental governance: the stone that the builders "forgot"

Governance
African Union
Pan African parliament
Africa
The African Union is an inter-governmental arrangement aimed at fostering democratic ideals and development on the African continent. The metamorphosis of inter-governmental arrangements has led to the need for the inclusion of the civil society in the decisions of such organisations on the basis that at the heart of democracy lies public and inclusive governance. The Pan-African Parliament is one of the organs of the African Union as envisaged in Article 5(1)(c) of the Constitutive Act. The Pan-African Parliament was formally inaugurated in 2004. It attempts to secure the full participation of African people in the development and economic integration of the continent by providing a platform for civil society participation. the importance of having a legislative and oversight body especially in organisations at a continental scale cannot be over emphasised, however the manner in which the Pan-African Parliament has been established leaves much to be desired. this paper will analyse the institutional arrangements around the establishment of the AU and in particular, the Pan African Parliament. It will illustrate the importance of civil society participation in governance and determine whether the African Union has attained an acceptable level of civic-inclusive arrangements in its architecture.

Data Structures and Algorithms is a module in most Computer Science or Information Technology curricula. It is one of the modules most students identify as being difficult. This paper demonstrates how programming a solution for Sudoku can make abstract concepts more concrete. The paper relates concepts of a typical Data Structures and Algorithms module to a step by step solution for Sudoku in a human type as opposed to a computer oriented solution.

Regulatory frameworks
Managing receipt of gifts

Sedibeng District Municipality
This paper seeks to analyse South Africa’s regulatory frameworks relating to the receipt of gifts in the Public Service in order to assess the mechanisms for management of this practice in Sedibeng District Municipality (SDM). the paper reports a study that adopted a qualitative approach to conduct desktop, questionnaire and interview surveys. Whereas desktop study was used to compile information on the regulatory frameworks relating to this phenomenon, questionnaire and interviews were administered within the SDM to determine the extent of the gifts receipt practice. The paper finds that worldwide, the acceptance of gifts in the Public Service and private sector is a common frequently experienced phenomenon largely due to the negligible attention placed on these practices in the codes of conduct/ethics. the SDM survey results show that the absence of clear principles makes it difficult to foster existing regulatory provisions for managing receipt of gifts, thereby undermining efforts towards the prevention of corruption. The paper presents recommendations that could potentially enhance the management of gifts in Public Service.

We describe the integration of several tools to enable the end-to-end development of an Automatic Speech Recognition system in a typical under-resourced language. Google App Engine is employed as the core environment for data verification, storage and distribution, and used in conjunction with existing too ls for gathering text and for speech data recording. We analyse the data acquired by each of the tools and develop an ASR system in Shona, an important under-resourced language of Southern Africa. Although unexpected logistical problems complicated the process, we were able to collect a usable Shona speech corpus for the development of the first Automatic Speech Recognition system in that language.

Design science research
Interpretive research
Qualitative data
Interviews
Real application environment
Design science research has two essential processes, design and evaluation, supported by various approaches. Two of these activities, namely problem identification and evaluation, require qualitative data to be gathered by means of interviews. Despite its strengths, the analysis of qualitative data gathered from an interview, is not popular with researchers in design science research. Most design science researchers are trained in the technical aspects required for artefact design and development and find qualitative data collection and analysis outside their field of expertise. Although there is no shortage of general research on qualitative approaches, there is a shortage of includes a multitude of approaches like studying documents, using focus group interviews and the observation of an environment. This paper demonstrates a seven step process for using qualitative data gathered from an interview with a client – to facilitate the understanding of the real application environment and to assist in the evaluation of the artefact from an interpretive research perspective.

This paper reports on the analyses of a custom-made questionnaire distributed to systematic random selected teachers in 179 schools in the Western Cape Province, South Africa. The purpose of the analysis was to enquire what Mathematics in the Western Cape Education Department regard as essential elements to develop their social professional identity for online professional engagement. The Statistical Consultation Services of the North-West University conducted a principal axis factor analysis to validate the correlation coefficient between the factors of the questionnaire and cluster the factors into eleven essential elements. A Cronbach Alpha of 0.7 for most of the factors validated the reliability of the extracted factors. Engelström’s Third Generation Activity Theory Model conceptualized the factors. Mathematics teachers regard the provision of resources, access to personal and virtual learning environments and adequate professional development models and framework as components for the transformations of the social professional identity for professional online engagement.

Complex enterprise-wide projects often fail even when formal project management methods are followed. Project management processes and methodologies are well defined and described in academic and business literature. There is however less published research on the human factors that are critical for project success. This paper describes the results of a study on whether project stakeholders view communication as one of the critical success factors for project success. Critical project success factors were identified from a literature study and ranked by 34 project stakeholders using a comparative analysis technique. The results were translated into a project success factor model that explains the importance of communication in project success. The results of this research project support the view that communication training across stakeholder groups should be included as an integral part of the enterprise-wide project risk mitigation tool kit.

This paper analyses the economic impact of residential electricity theft. Theft and corruption are common in electricity distribution systems worldwide. Electricity theft form part of the revenue protection objectives in the electricity sector. The paper examines the processes adopted for prevention of residential electricity theft in the Sedibeng District Municipality (SDM). Electricity theft in this paper is considered as any kind of fraudulent use of electricity. The irregularities in electricity sector mainly stems from the socio-political structure and institutional governance of the operating utilities. Residential electricity theft occurs wherein consumers (client) and utility employees (agents) collude for their respective gains, thereby causing loss to the utility/government (principal). Consumers dishonesty inhibit the utility from receiving the full price of the power it sold, which harms the financial health of local distribution companies and franchises, creating deleterious effects on future investments in the power sector and local economic growth. Besides examining detection and enforcement processes, this paper argues that corruption not only stifles growth, it also perpetuates or deepens inequality, as the few amass power and wealth at the expense of the many. To this extent, the paper hopes to unpack the anatomy of electricity theft through analyses of pertinent literature and interview survey results from the Vereeniging branch of the SDM.

When modelling code-switched speech (utterances that contain a mixture of languages), the embedded language often contains phones not found in the matrix language. These are typically dealt with by either extending the phone set or mapping each phone to a matrix language counterpart. We use acoustic log likelihoods to assist us in identifying the optimal mapping strategy at a context-dependent level (that is, at triphone, rather than monophone level) and obtain new insights in the way English/Sepedi code-switched vowels are produced

The aim of this study was to investigate how communication is affected by the different cultural contexts of information system development (ISD) team members in order to achieve ISD project results. The study investigated the level of difficulty of communication with ISD team members from different cultural context such as cultural affiliation, job class distinction, language, non-verbal communication, group size, gender, age, and profession. A qualitative, interpretive multiple case study was conducted in Gauteng province of South Africa where ISD team members were interviewed. The results may show that South Africans have made big strides since the first democratic elections of 1994.

This research paper covers the development of an HIV risk scorecard using SAS Enterprise MinerTM. The HIV risk scorecard was developed using the 2007 South African annual antenatal HIV and syphilis seroprevalence data. Antenatal data contains various demographic characteristics for each pregnant woman, such as pregnant woman's age, male sexual partner's age, race, level of education, gravidity, parity, HIV and syphilis status. The purpose of this research was to use a scorecard to rank the effects of the demographic characteristics on influencing an individual's risk of acquiring an HIV infection, not the probability of being sick. The project encompassed the selection of the data sample, classing, selection of demographic characteristics, fitting of a regression model, generation of weights-of-evidence (WOE), calculation of information values (IVs), creation and validation of an HIV risk scorecard. The educational level and syphilis status of the pregnant women produced information values below 0.05 and were rejected from inclusion in the final HIV risk scorecard. Based on their respective information values, the following four demographic characteristics of the pregnant women were found to be of medium predictive strength and thus included in the final HIV risk scorecard; age, age of male sexual partner, gravidity and parity. The age of the pregnant woman had the highest information value and Gini coefficient. The HIV risk scorecard showed that the risk of contracting an HIV infection increased gradually up to the age of 30 years for females and 34 years old for their male sexual partners. Thereafter, the risk decreased gradually towards the age of 45.

In this article, the author looks at “emergence” in the context of new concepts of God in the Old Testament. Within biblical scholarship, various types of emergence are alluded to in various methodological reductions, i.e. via theological, historical-comparative, sociological and literary-critical approaches to the text. From a philosophical perspective on the Old Testament as a complex system, however, emergent properties of YHWH are instantiated in the paraconsistent logic operative in fictional discourse.
