Integration of social media records into enterprise content management at the South African Broadcasting corporation in the Limpopo Provincial office in South Africa

Masekoameng, Moshohli Frans 03 1900 (has links)
The integration of social media records into enterprise content management systems is crucial to organisations as it enables them to have access to these records if they are required for evidential purposes. However, despite social media content being considered as official records in state-owned enterprises, they are often left unmanaged. The purpose of this study was to investigate the integration of social media content into the enterprise content management system at the South African Broadcast Corporation Limpopo provincial office in South Africa. The study utilised quantitative data collected through questionnaires distributed to SABC employees and employees at three radio stations in the Limpopo provincial office (Munghanalonene FM, Thobela FM and Phalaphala FM). The key results suggest that there were no policies or guidelines on the management of digital records that emanated from social media. It was discovered that the SABC’s Limpopo provincial office opened official accounts with various social media platforms such as SNSs, online content communities and podcasts to use for official matters; yet content generated through these platforms is neither managed nor preserved. It has been established that the responsibility of managing social media content is unconsciously assigned to the creators of the content as no official records management responsibilities were assigned. It is recommended that digital records emanating from the use of social media by the staff of the SABC Limpopo provincial office need to be treated and managed as official records, like all other paper-based records. In this regard, a policy for integration of social media content into enterprise content management is desirable. A further study on the development of a framework to integrate social media content into organisational records management is recommended. social media content, social media platform, enterprise content management, digital records, records, records management, online content communities, South African Broadcasting Authority. / Information Science / M.A.(Information Science)

Isolation, propagation and rapid molecular detection of the Kalahari truffle, a mycorrhizal fungus occurring in South Africa

Adeleke, Rasheed Adegbola 03 April 2013 (has links)
Terfezia pfeilii is an edible mycorrhizal fungus that thrives in the Kalahari Desert of southern Africa. It is best known by desert dwellers for its flavour and as a source of nutrition. Although the genus Terfezia is generally regarded as being an ectomycorrhizal mycobiont, the exact mycorrhizal type formed by T. pfeilli and its' associated host plants remains uncertain. Discovery of the host plants for T. pfeilii would first be required in order to further investigate the life cycle and cultivation of this truffle. This study focussed on the isolation of mycelia from the ascocarp, optimising the growth conditions of the mycelial cultures, rapid molecular identification of T. pfeilii, investigation of potential helper bacteria and mycorrhizal synthesis experiments. T. pfeilii ascocarps were harvested from the Spitskop Nature Reserve in Upington, South Africa. Ascocarps were successfully identified using both morphological and molecular methods. Despite the delayed growth mostly caused by contaminating microorganisms, the isolation of T. pfeilii mycelia culture was successful. Molecular techniques were used to confirm the identity of the pure culture. Further studies were conducted on ways to improve the growth conditions of the mycelial culture on Fontana medium. An optimum temperature of 32°C, the addition of Bovine Serum Albumin as a nitrogen source and a pH of 7.5 significantly improved the growth of T. pfeilii in vitro. A rapid PeR-based molecular method was developed to speed up the identification of T. pfeilii. Specific primers that can exclusively amplify the ITS region of T. pfeilii were designed and used to identify both the ascocarps and the mycelial culture. The specificity of these primers was confirmed by their inability to amplify DNA from the isolates of contamining fungi obtained during the isolation process. Molecular comparison was made to confirm the reclassification of South African samples of T. pfeilii as Kalaharituber pfeilii as proposed by Ferdman et al.,(2005). However, in this study, the name T. pfeilii has been retained. A total of 17 bacterial isolates were obtained from the fruiting bodies of T. pfeaii and these were tested for stimulation of mycelial growth in vitro, indole production and phosphate solubilising capabilities. Bacterial isolates that showed potential to be Mycorrhization Helper Bacteria (MHB) were identified as Paenibacillus sp., Bacillus sp. and Rhizobium tropici. Selected plant seedlings were inoculated with T. pfeilii cultures or ascocarp slurry in order to re-establish the mycorrhizal association. After 8 months, light microscopy observations revealed an endomycorrhizal type association between Cynodon dactylon and T. pfeilii. This was confirmed with molecular analysis using specific T. pfeilii ITS primers. After 15 months, molecular methods confirmed Acacia erioloba as another host plant. These results have provided essential information paving the way for further investigation into the life cycle and biology of the Kalahari truffle. / KMBT_363 / Adobe Acrobat 9.53 Paper Capture Plug-in

Newsroom convergence at the Mail & Guardian: a case study

Van Noort, Elvira Esmeralda January 2008 (has links)
This case study researches newsroom convergence as a process at the Mail & Guardian newspaper and their online edition the Mail & Guardian Online. It focuses on the reporters’ and editors’ attitudes towards newsroom convergence and on cultural resistance against change; one of the major challenges in the process. With structured interviews, observations and questionnaires it was analysed that communication problems between the newsrooms, different production cycles and time management issues are other prominent difficulties. The case study furthermore provides a snapshot of the convergence phenomenon as a process in a particular South African news organisation. The outcomes could not only assist other news companies with convergence plans but also be used as a pilot study for further research on converged newsrooms in South Africa.

Struggle in discourse the International's discourse against racism in the labour-movement in South Africa (1915-1919)

Caldwell, Marc Anthony January 1997 (has links)
The International, as the weekly newspaper of the International Socialist League, articulated from 1915 to 1919 an ideology which stood opposed both to organised labour and nationalist movements in South Africa. This situation reflected significant historical struggles during this period, which constitutes essential background to the discourse of the International. The International's writers opposed the institution of trade unionism in the labour movement because it was fragmented on the lines of skill and race. They opposed both the National Party and the South African Native National Congress because they advocated racial (and national) rather than working class interests. Instead, these writers, according to their international socialist paradigm, advocated a working class united irrespective of race and skill at the level of industry. To analyse these ideological positions, discourse analysis provides a fruitful method for locating its dynamics in relation to other positions and extra-ideological (contextual) practices: The International's writers g~nerated a socialist position against racism by engaging in an ideological struggle in discourse. They articulated their anti-racist position from international socialism's critique of the 'languages' of both militarism and trade unionism in the discourse of labour. Within the discourse of militarism, the working class was signified as divided between hostile nations. These writers applied this as a metaphor to the division of the local labour movement and criticised the latter accordingly. In their view, just as workers were divided between the nations (nationalism), so they were divided within the nation (racism) in South Africa. One context cohered with the other, and both agreed with imperatives of international capitalism. This was fundamentally opposed to the principles of international socialism which characterised the International's discourse. Within the dominant discourse oflabour, workers were signified as divided between different trade unions on the basis of skills. Furthermore, in the South African context, trade unions organised only white workers, and ignored the far larger proportion of black labour. In this context, the International advocated industrial unionism, and criticised the narrow base of the white trade unions for fragmenting and weakening the working class in South African. The International's writers were thus led by the discourse of international socialism to a new discourse, whereby not white workers alone, but a racially-united working class movement would be the key to a socialist future in South Africa. Their struggle entailed a bid in and over discourse to rearticulate the sign of the 'native worker' within their own discourse as the dominant discourse type. Underpinning their struggle was a fundamental opposition to capitalist class relations.

An investigation of Internet usage among a group of professionals in South Africa : a uses and gratifications approach

Gilbert, Juliet Francis 07 1900 (has links)
New mass media impact on the nature of public communication and the use and gratification of existing mass media because each new medium is used and experienced differently. As a new mass medium, the Internet offers different forms of communication, such as Internet Relay Chat, Multi-User Dungeons and chatrooms. It has also combined traditional mass media, namely print, radio and television, into a single powerful medium. Due to the fact that the Internet is still an emerging medium, its long-term effects on the nature of public communication and traditional mass media warrants ongoing investigation. The first part (Part A) of this dissertation situates the Internet chronologically within the development of traditional mass media and their impact on public communication. Part B investigates Internet use among a group of professionals in South Africa. The objective is to identify how they use the Internet and the gratification they derive from it. / Communication Science / M.A. (Communication)

The South African Broadcasting Corporation in the age of social media

Lefowa, Lufuno 31 July 2016 (has links)
This is an exploratory study conducted to assess the way in which social media could enhance the experience for audiences of the South African Broadcasting Corporation (SABC) television drama. This study focused on Facebook and Twitter since they are two of the top five social media networks that are popular in the country and which have the potential to offer television more mileage in terms of communicating with its audience and extending its reach. The guiding theory for this study was uses and gratifications theory. This theory was employed to assist in assessing the opportunities that exist for SABC television drama, as well as to assess the ways in which the audience believe social media could be helpful in interacting with SABC television drama. The results for this study are interesting in that the majority of respondents believed that having a hashtag on screen during a drama broadcast would help to increase interactivity with the programme, as it could help direct audiences to the correct interactive space for that programme and they would be able to share their ideas and comments on the drama directly with the producers, making feedback immediate. It was interesting to note that the respondents believed that they could interact with SABC television drama for information relating to the story. The findings suggest that SABC television drama needs to actively adopt social media in its programmes for maximum interaction. There is also the need for an understanding of how they Facebook and Twitter could be embedded in SABC drama. / Communication Science / M.A. (Communication Science)

Social media use among NMMU students

Mohamed, Hassan January 2011 (has links)
This research provides insight into the use of social networks and social media by students at the Nelson Mandela Metropolitan University. The primary purpose of this research is to investigate student social media practices at NMMU to establish the reasons for students engaging in social media. A growing number of educators acknowledge the potential of social networking to (re)engage learners with their studies, while others fear that such practices compromise and disrupt student engagement with traditional education provision (Selwyn, 2009). This study, therefore, aims to identify how and for what reasons students use social networks and social media. This study attempts to provide answers to the following research questions: For which social networking sites do students register and actively engage in? What is the most popular social networking site for students? How often do students engage in social media practices? What is the main purpose for students engaging in social media practices? How do students gain access to social media? For what educational purposes can social media be used? For which business purposes can social media be used? Do students use social media to collaborate with peers and lecturers? Do students use social media to make buying decisions? The literature overview was conducted on social media and social networks from journals and books published between the periods 2003 to 2011 as the popularity of social media came to the forefront during this period. Topics researched included social networks and libraries, educational and business uses of social networking and social media. A quantitative study was considered to be most appropriate to conduct the research for this study; and non-probability sampling was the most appropriate given the size of the population and the nature of this research. xiv Students were invited to participate in the research by completing and submitting a survey questionnaire at the conclusion of their lectures in the second semester during the month of September. The data collected was then analysed using descriptive and inferential statistics to provide insight into student use of social media. The results would determine if relationships exist between the independent variables from the questionnaire, namely, age, gender, campus and course enrolment and the dependent factors, namely, usage, information exchange and security. This relationship would be determined for both the perceptions of social networking in general and the perceptions of NMMU social networking. These results are then used to identify further areas of research in the future. The majority of the population sample was between the ages of 17 and 21 and primarily females. The sample typically became aware of social media by means of word-of-mouth and accesses their social networking site/s more than five times a day. The main reason for registering and joining social networking sites was for social purposes. Furthermore, the sample used social networking sites for entertainment, social involvement, meeting new friends and maintaining relationships. The sample agreed that social networking makes information searching easier. The majority of the sample indicated that they were not registered on any NMMU Social Networking sites of the university or any faculty, department or unit social networking sites at the NMMU. However, it was clear that the majority of students was registered on social networking sites of some sort and would continue to use social networking and social media. The results from the study indicated that the mean value for the perceptions of social media in general were greater than that of the perceptions of NMMU social media in terms of usage. Likewise, the mean value for the perceptions of social networking in general was also greater than that of the perceptions of NMMU Social Networking for information exchange but the difference were very small. However, the mean value for the perceptions of NMMU Social Networking showed a greater mean value than that of the perceptions of social networking in general in terms of security. This means that respondents used social networking in general more than NMMU Social Networking. xv However, the respondents perceived NMMU Social Networking sites to be more secure than social networking sites in general. The results of this study could provide Higher Education Institutions in South Africa with the impetus to use social networks and social media to enhance students‟ learning experiences.

Implementation of a facebook crawler for opinion monitoring and trend analysis purposes: a case study of government service delivery in Dwesa

Mfenyana, Sinesihle Ignetious January 2014 (has links)
The Internet has shifted from the Web 1.0 era to the Web 2.0 era. In the contemporary era of web 2.0, the Internet is being used to build and reflect social relationships among people who share similar interests and activities. This is done through services such as Social Networking Sites (Facebook, Twitter etc.) and the web blogs. Currently, there is a very high usage of Social Networking Sites (SNSs) and blogs where people share their views, opinions, and thoughts. This leads to the production of a lot of data by people who post such content on SNSs. As a result, SNSs and blogs become the ideal platforms for opinion monitoring and the trend analysis. These SNSs and Blogs could be used by service providers for tracking what the public thinks or requires. The reason being, having such knowledge can help in decision making and future planning. If service providers can keep track of such views, opinions or thoughts with regard to the services they provide, they can better their understanding about the public or clients’ needs and improve the provision of relevant services. This research project presents a system prototype for performing opinion monitoring and trend analysis on Facebook. The proposed system crawl Facebook, indexes the data and provides user interface (UI) where end users can search and see the trending of a topics of their choice. The system prototype could also be used to check the trending topics without having to search. The main objective of this research project was to develop a framework that will contribute in improving the way government officials, companies or any service providers and normal citizens communicate regarding services they provide. This research project is premised on the conceptualization that if the government officials, companies or any service providers can keep track of the citizen’s opinions, views and thoughts with regards to services they provide it can help improve the delivery of such services. This research and the implementation of the trend analysis tool is undertaken in the context of the Siyakhula Living Lab (SLL), an Information and Communication Technologies for Development (ICTD) intervention for Dwesa marginalized community.

Policing mechanisms to counter terrorist attacks in South Africa

Kalidheen, Rufus 31 March 2008 (has links)
Terrorism remains a cardinal threat to national, regional, and international peace and security. It violates the fundamental principles of law, order, human rights and freedom and remains an affront to the Global Charter of the United Nations (UN) and the values and principles enunciated in Africa's Constitutive Act of the African Union (AU). Moreover, it presents a grave and direct threat to the territorial integrity, security and stability of States. In this regard, effective counter terrorism mechanisms and approaches remain fundamental tools in curbing the threats and devastating effects of terrorism. Since the advent of the 'war on terror', issues regarding terrorism and counter-terrorism have become pronounced norms within the international realm. Yet, while an abundance of literature has been focussed and analyzed on counter terrorism approaches within the United States (US), the United Kingdom (UK), Russia and India; little has been documented on effective counter terrorism approaches in South Africa post-2001. Given emerging trends of terrorist camps within the country and the fact that South Africa will be hosting the international event of the 2010 FIFA Soccer World Cup, it is imperative that South Africa improves the overall direction of its counter terrorism strategy. Essentially, this study offers recommendations for the most effective counterterrorism mechanism, which will aid policing in South Africa. History and current events indicate that South African Police Service (SAPS) has the capacity and capability to successfully deal with threats of terrorism. What is lacking is a concrete proactive counter terrorism approach that makes SAPS stand out as the lead department in countering terrorism. Yet, it should be borne in mind that the most important principle of any counter terrorism operational concept is to co-ordinate an operation with an integrated approach. Bearing this in mind, this study includes an assessment of the counterterrorism methodologies of various agencies responsible for counter terrorism within South Africa, with SAPS being the focal point. To establish the most effective counter terrorism strategy applicable to the South African context, this study considers a comparative analysis of counter terrorism strategies adopted within specified developed (Russia, US and UK) and developing countries (India and Algeria) as well as a conceptual analysis of relevant policing mechanisms that are currently considered as appropriate mechanisms to counter terrorism within specified countries. The synopsis of best-case practices of counter terrorism in developed and developing countries as well as the relevant literature on policing mechanism are then synthesized and interrogated into conceptualising an effective policing mechanism to counter terrorism in South Africa. / Criminology / M.

Media usage and preference of consumers in the Transkei

Smit, Johannes Jacobus 11 1900 (has links)
The objective of this study is to establish the media usage and preference of consumers in the Transkei. The results are of special significance to media planners and advertisers in so far as they will assist in the media selection process. This in turn will form the basis of improved marketing communication between media planners and advertisers on the one hand and Transkeian consumers on the other. The media types investigated were newspapers, magazines, television and radio. The results indicated that three newspapers (Daily Dispatch, Intsimbi and Imvo), three magazines (!bona, Pace and Orum), one television channel {TV 2 - now CCV-TV) and one radio station (Radio Transkei) are extremely popular among the majority of Transkeians. The research results also indicated that the following topics are very popular in all the media types: local news, sport, education and arts/cultural articles. The results further indicated that Transkeians are generally favourably inclined towards advertisements. / Economics / M.Com (Business Economics)
