- Description: The legal framework and legislation governing the rights of the children have become of great concern in modern societies, particularly, in the area of criminal justice and human rights. The Convention on the Rights of the Child and African Charter on the Rights and Welfare of the Child are basic international and regional conventions regulating the rights of the children and include how to deal with children in conflict with the law. States parties to these conventions are required to take appropriate measures, which includes enactment of legislation to give effect to these rights. Legislative instruments must address the following issues: The principle of the best interest of the child; the age of criminal responsibility; restorative justice; diversion; and the trials of children in conflict with the law. The above-mentioned instrument require and emphasise the use of an alternative approach in respect of the children who are in conflict with law. In this research a comparative approach is used to compare the South African and South Sudanese child justice legislative instruments. The legislative instruments pertaining to child justice in both countries are set out and compared. It is concluded that the South African legislative instruments are more aligned to the Convention on the Rights of the Child and African Charter on the Rights and Welfare of the Child. Recommendations and proposals are made to enact to adopt in South Sudan new legislative measures and provisions aim to afford more protection to children in conflict with the law and to strike a better balance between rights of a child and victim of crimes.

- Description: Cobalt phthalocyanine (CoPc) and cobalt phthalocyanine carboxylic derivatives (CoTCPc and CoOCPc) have been used as electrocatalysts for the detection of the antioxidants vanillic acid, caffeic acid, pyrogallol, and ascorbic acid on screen-printed carbon and disk electrode surfaces. The cobalt phthalocyanines were used to detect vanillic acid (with limit of detection ranging from 1.15 μM to 2.42 μM at potentials of 0.55–0.88 V vs. Ag|AgCl), caffeic acid (with limit of detection ranging from 1.17 μM to 2.20 μM at potentials of 0.30–0.81 V vs. Ag|AgCl), pyrogallol (with limit of detection ranging from 1.16 μM to 3.63 μM at potentials of 0.52–0.63 V vs. Ag|AgCl), and ascorbic acid (with limit of detection ranging from 1.16 μM to 1.58 μM at potentials of 0.34–0.46 V vs. Ag|AgCl). The kinetic studies also demonstrate diffusion-controlled processes at the electrode surface. The SPCE electrodes have better detection properties towards vanillic acid, caffeic acid, pyrogallol while the disk electrodes had better ascorbic acid detection properties as proven by kinetic studies. Both types CoPc-influenced electrodes show 100% discrimination of the antioxidants.

- Description: The overall objective of the study was to investigate the relationship between male circumcision status and HIV infection in men from Salima district in Malawi. A cross-sectional survey-based study of men aged 15 years or more was conducted at three sites in Salima district, each of which targeted 90 participants, half of whom were circumcised and the other half uncircumcised. These participants had already decided on their own to visit HIV Testing and Counseling centres at these sites to know their HIV serostatus. Consenting men were drawn into the study using quota sampling, interviewed through a structured questionnaire in local language and tested for HIV during January and March 2011. Measures of association were performed using analysis of contingency tables and Pearson’s chi-square tests or Fisher’s exact tests for comparison of proportions in STATA version 11.0 and PASW Statistics 18.0 software. Unadjusted odds ratios were used to approximate the direction and strength of association. Further, a multivariable logistic regression model was fit to determine which other variables were significantly associated with HIV infection. The study was approved by University of Fort Hare Interim Research Ethics Committee and National Health Sciences Research Committee in Malawi. The overall prevalence of HIV infection was 11.5 percent. However, it was less than half in circumcised males (7.4 percent) compared with uncircumcised counterparts (15.6 vi percent). While Fisher’s exact test revealed a borderline statistically significant association between male circumcision status and HIV infection (p 0.055), Pearson’s chi-square test showed a stronger significant association between the two variables ( p 0.036). The strength of the association was manifested by the odds of HIV infection being roughly 0.43 times lower for circumcised males than their uncircumcised counterparts with a 95 percent confidence interval of (0.20 0.96). Although the association was maintained after controlling for some variables, it lost statistical significance when adjusted for other variables. A multivariable logistic regression revealed that three other variables had significant associations with HIV infection and these were: falling in the age group of 25 years or more (OR 4.69; p 0.020), having had sex with an HIV positive partner (OR 12.15; p 0.000) and having contracted a sexually transmitted infection (OR 3.25; p 0.032). Male circumcision status is significantly related to HIV infection. Although the study involved a small sample size and undertaken in one district in Malawi, the finding is consistent with existing clinic-based findings in literature that indicate a lower risk of HIV infection in circumcised males than in uncircumcised males. Consequently, male circumcision could be considered if it can prove to be a public health intervention in the Malawi context aimed at reducing the risk of uncircumcised males becoming infected by HIV.

- Description: This study reviews a training programme on Marine Protected Area (MPA) management. It notes that although MPAs are well promulgated under legislation, reports have found that there are still key challenges facing the management of these areas. The research examines how the course was developed following the Lemm and Attwood (2003) report and designed to develop competences for effective MPA management. The aim is to identify how a MPA management training course produced competences apposite to the workplace settings of the participants. An interpretive case study method was used, in two phases. The first phase explored salient issues in MPA management in South Africa through analysis of the two key ‘state of MPA management’ reports and interviews with MPA professionals. The second was an analysis of the South African Marine Protected Area Management Training Course. This involved interviews with course designers, a review of the course materials, interviews with past course participants, and an analysis of course evaluations. Evidence emerged that supported the following findings: Challenges and problems facing MPA management still exist. Competence in key areas of MPA management was addressed in an effective work-integrated approach. Social learning was a key process in the development of these competences. The competences articulate well with the workplace of participants. Gaps exist between some of the management issues and the competences developed by the course, and some aspects of the course design are ineffective. From these findings it is concluded that: The course took up the majority of issues in MPA management through the development of key competences. The course design facilitated the development of these competences. The competences developed through the course are relevant to the workplace of MPA professionals. The research found that the course adequately addresses issues in MPA management through the development of competences. Some recommendations for improvements are made.

- Description: This article reports on the comprehension and production of figurative language, namely idioms and similes, in first language Afrikaans-speaking (AFR) boys, ages eight to 10 years, and first language Afrikaans-speaking boys with specific language impairment (SLI), also ages eight to 10. It draws on a larger study by Van der Merwe (2007; see also Van der Merwe & Southwood, 2008). Testing of the comprehension and production abilities of the children was conducted verbally and individually and elicited their understanding of 25 idioms and 25 similes. The idioms were first presented without context; if the child gave an incorrect interpretation, the idiom was placed in context. Raw scores show that the SLI group performed marginally more poorly than the AFR group, but there was no statistically significant difference between the comprehension of idioms by the two groups. The same can be said for the number of literal interpretations provided by the groups. Placing the idioms in context was beneficial to both groups. The simile completion task required the children to provide the last word of each simile. For both groups, the similes task proved to be easier than the idioms task but there was again no statistically significant difference found between the two groups. The results seem to imply that children at this developmental phase, aged eight to 10, whether language impaired or not, have not yet fully grasped figurative language as a concept and need explicit instructions on figurative language. The article ends with a reflection on the suitability of idioms and similes as particular categories of figurative language in studies of this nature.

- Description: Despite coelacanths, Latimeria chalumnae, being listed as either endangered by CITES or critically endangered by the IUCN, their population size within South Africa is unknown and still needs to be estimated. Their conservation status unfortunately excludes the use of conventional tagging to mark individual animals for a possible mark-recapture experiment. This study shows that because coelacanths have a unique spot patterning it is possible to quickly and accurately identify specific individuals photographically using computer-aided identification software. Without any manual intervention by an operator, the software accurately identified between 56 and 92% of the individuals. Indentification success increased to 100% if the operator could also manually select from other potential matching photographs. It was also shown that fish exhibiting a yaw angle not exceeding 60˚ could be accurately identified in photographs, although the percentage of fish correctly identified without operator-intervention decreased rapidly with increasing yaw angle. Computer-aided identification should therefore facilitate future coelacanth research as it is both efficient and accurate while also reducing potential stress on the animals observed.

- Description: The purpose of the study was to explore the relationship between WFC and stress with Conscientiousness which is part of the Big Five personality Traits Model in moderation. The study was undertaken in the South African Police Service members in Alice town in the Eastern Cape. The study was based on a sample size of eighty four (n=84) out of 134 (N=134) police officers. A simple convenient random sample was used to sample participants. With the use of descriptive, correlation and inferential statistics the finding revealed instead that Conscientiousness has no significant relationship with WFC at (r= 0.02792, p= 0.8022) also Conscientiousness had no significant relationship with stress at (r= -0.04465, p= 0.6885). Overall, after separating the group according to those that scored low and those that scored high on conscientiousness scale, the study found the group low in conscientiousness not significantly correlated with WFC and stress (r= -0.02263, p= 0.9414). and the group with a high conscientiousness the study revealed a high significant relationship for police officers that scored high on Conscientiousness at (r= 0.40119, p< 0.00). The group low in conscientiousness has no correlation between WFC and stress thus different values of conscientiousness cause a change in the relationship between WFC and stress. Thus those who are low in conscientiousness do not have a relationship between WFC and stress. A call is made to the SAPS as an institution to consider prioritizing personality trait particularly applicants that score low on conscientiousness personality test during recruitment and selection of new police officers to avoid the outcomes associated with the nature of police work.

- Description: In spite of the fact that informal traders in the informal economy are viewed as having the greatest prospects for creating jobs and absorbing the unemployed in developing countries, informal traders in Limpopo Province in general, and the city of Polokwane in particular, face various constraints that negatively affect them on a daily basis. The aim of the study has been to explore the constraints and opportunities of informal traders, using the city of Polokwane as a case study. The study has attempted to identify and describe constraints that affect informal traders in the Polokwane city, as well as factors that can enhance their development and growth. The study is exploratory, descriptive and qualitative in nature. Semi-structured faceto-face interviews were conducted to gather data. Findings of the study suggest that the government should improve the effectiveness of its support mechanisms by initiating targeted support programmes specifically tailored for informal traders at the survivalist level.

The study is exploratory, descriptive and qualitative in nature. Semi-structured faceto-face interviews were conducted to gather data. Findings of the study suggest that the government should improve the effectiveness of its support mechanisms by initiating targeted support programmes specifically tailored for informal traders at the survivalist level.

- Description: The rate of obesity has risen dramatically over recent years and is an epidemic in many countries. School pupils and university students are no exception to this. The negative effects physically, mentally and emotionally of being overweight are detrimental to one’s quality of life. It is therefore critical to encourage pupils and students to participate in physical activity. Formalised sport is a key component of encouraging physical activity. The habits learnt in childhood and early adulthood are often carried through for the rest of one’s life. The benefits of participating in sport need to be promoted extensively to the students, as research has shown students that participate in sport are not only healthier but achieve better academic results. This study examined the constraints to students’ participation in formalised sport. The empirical data was collected by means of a survey, using self-administered questionnaires distributed to students on the three Summerstrand campuses at the Nelson Mandela Metropolitan University in Port Elizabeth. Two hundred and eighty three usable questionnaires were received. Time and scheduling was found to be the most constraining factor to participation in sport. I am too busy with my university studies attracted the highest mean score of all the items on the questionnaire. It is recommended that: • sport organisers at NMMU emphasise to the students the benefits of regular participation in physical activity; • the effectiveness of the current NMMU sport programmes and accessibility be further investigated as only 18 per cent of the students in 2011 were participating in sport programmes at NMMU; • time management skills be taught to the NMMU students as the Time and scheduling constraint was the most profound constraint to participation in formalised sport; • NMMU academic staff work more closely with the staff at the University Sport Bureau to promote regular sport participation and to disseminate sport related information that could promote being more actively involved in sport; and • relevant introductory sport programmes and more internal leagues be offered, that gently introduce various sport codes to the students.

- Description: South Africa's biggest challenge remains the high rate of unemployment especially among the country's youth. Small, medium and micro enterprises (SMMEs) have been shown to be instrumental in many third world economies as a sustainable means not only to address unemployment but also to contribute significantly to economic growth. Despite government's good intentions and support, the South African SMME sector is not growing as expected and this is impacting negatively on unemployment creation in the country. Good business development services (BDS) is necessary to support SMMEs and specifically the Market Development Approach to the provision of BDS, where subsidies are replaced by private payment for services. Makana municipal area provided scope for analysing the constraints to the implementation of such business development services. Analysing the scope and magnitude of the constraints in this setting would contribute to understanding the constraints also in other parts of the country and help officials in local economic development make better informed decisions regarding support to SMMEs. Authors like Rogerson (2011), UNDP (2004), Miehlbradt and McVay, (2003), the Committee of Donor Agencies for SME Development (Blue book) (2001) and Bear et al., (2001) Gibson (2001), propose that the key to sustainable BDS is the implementation of the Market Development approach which focusses on for-profit activities in the provision of BDS to SMMEs. The aim of this study was to examine perceptions of key stakeholders towards SMME support and development, to identify the constraints to the implementation of a Market Development approach to the provision of business development services to SMMEs in the Makana area and to make recommendations to the Makana LED office of possible intervention strategies to address identified constraints. Purposive sampling was used to identify key stakeholders in SMME support in the Makana area in the categories of, big institutional buyers, public and private BDS providers as well the municipal LED office. Semi-structured interviews were conducted with each stakeholder using questions shown in appendixes A to D. Perceptions of all key stakeholders were very positive with good intentions to support SMMEs. However, this was not consistent with procurement practice at the big institutional buyers. Constraints are summarized in the following five themes: Theme 1. Inconsistent practice in dealing with SMMEs across the organisation. Theme 2. Absence of a cooperative body or Chamber of Commerce. Theme 3. Fragmented Business Development Services. Theme 4. A lack of a culture of cost recovery. Theme 5. Limited awareness of BDS in the Makana area. A number of recommendations were suggested. Big institutional buyers like Rhodes University and Makana municipality need to take a longer term view and move the focus from employment creation to enterprise support which is a more sustainable and empowering source of employment (ILO, 2009). The Grahamstown Chamber of Commerce should become more representative and big institutional buyers also need to be convinced of the value of private BDS. Stakeholders should work together to combine resources to offer a comprehensive one-stop BDS for the Makana area (Chetty, 2009) and this comprehensive BDS should be provided according to the Market Development approach focusing on those services that lend themselves better to this approach whilst using subsidies only for those services with a low potential for cost recovery (UNDP, 2004).

- Description: Tuna are of significant global economic importance and a prime food source. Increased levels of fishing have resulted in many stocks being under threat and a number of species are considered to be overfished. The South African tuna industry has had limited management attention from the South African fisheries management agency. A recent development has been an increase in the number of tuna caught by small vessels that target the fresh tuna market in South Africa and overseas. This has highlighted the importance of developing a holistic management plan for the sector and creating an awareness, among vessel owners, of the importance of compliance with initiatives such as the Marine Stewardship Council (MSC). The South African tuna fishery comprises three sectors: baitboat, sport and longline, all of which are currently in need of acquiring more biological and fisheries data. This project was initiated to collate existing information and to collect additional information where possible. This encompassed a qualitative and quantitative assessment of the size and shape of the tuna fishing industry, which included estimates of total catch, effort, catch-per-unit-of-effort (CPUE) and stock structure (obtained through comparative estimates of age and growth), as well as socio-economic and economic information. A technique involving an examination of specific vertebrae was used to obtain age-growth information for T. albacares. These data were used to estimate von Bertalanffy (VBGF) growth parameters: F 2 1. , k 0.1 , and t₀ -0. 1 year. No significant differences in growth parameters were found in yellowfin tuna (Thunnus albacares) from different localities around the South African coast, i.e. from the south eastern Atlantic and the south western Indian Ocean. In addition, growth did not differ between South Africa and other regions (Draganic and Pelzcarski 1984, Fonteneau 1980, Gascuel et al. 1992, LeGuen and Sakagawa 1973, Lehodey and Leroy 1999, Lessa and Duarte-Neto 2004, Shuford et al. 2007, Stequert et al. 1996, Wild 1986, Yang et al. 1969). Further substantiation of the above-mentioned observations was found by recording differences in the sizes of fish caught in the inshore (baitboat and sport fishery vessels) and offshore (large pelagic longline vessels) sectors of South African tuna fisheries. A significant difference between the regions — in terms of the size of fish caught inshore — was noted, with mostly-juvenile fish being caught in KwaZulu-Natal (5.4 ± 3.5kg), sub-adult fish in the Eastern Cape (26.2 ± 13.4kg), and adult fish in the Western Cape (42.3 ± 14.4kg). Since mostly-adult fish were caught offshore by longliners, with no significant differences between regions, it is however possible th at adult fish predominantly inhabit the offshore region. Yellowfin tuna caught by the large pelagic longline fishery in the three managerial zones (A, B and C) were predominantly adult fish of similar size, namely Zone A: 38.9 ± 6.9kg; Zone B: 28.7 ± 4.6kg, and Zone C: 36.0 ± 5.1kg. The recreational ski boat sport fishery has remained stable, in terms of participation, consisting mostly of white middle aged males in the top 25% of household income distribution, having either permanent occupational status or being retired. Fishers within this sector are willing to incur great expense to partake in the fishery and they provide an important economic contribution to coastal towns, particularly in the Eastern Cape. The total catch (of 83t) of yellowfin tuna by the competitive sport fishery within the Western and Eastern Cape regions was considerably lower than that of commercial tuna baitboat catches, which amounted to 186t, and the large pelagic longline sector that caught t in 200. It is however likely that the competitive sport fishery's total yellowfin tuna catch (of 83t in 2009) of the Eastern and Western Cape competitive sport fishery was considerably less than the total yellowfin tuna catches of the whole South African deep-sea sport fishery. Longfin tuna are the primary target species of South Africa‘s baitboat fisheries, comprising an average of 86% of the total catch and generating ZAR49 million in employment income in 2002. South Africa was responsible for 20% of the total longfin tuna annual yield in 2004 in the southern Atlantic Ocean, behind Taiwan with 59%. However, yellowfin tuna only contributes a small percentage towards total catches (8.4 ± 8.2% between 1995 and 2009), generating ZAR1.3 million in employment income in 2002. Of the four vessel categories comprising the tuna baitboat fishery, ski boats had the highest yellowfin tuna CPUE in 2009 (117 ± 62 kg.vessel⁻¹.day⁻¹) and the lowest effort. The ski boats sector is the most opportunistic fishery as they are only active when either longfin or yellowfin tuna are in high abundance. At such times catches are guaranteed, so can be expected to offset expenses. In 2009 the CPUE for yellowfin tuna for 15–19m vessels and freezer deckboats was 12 ± 20kg.vessel⁻¹.day⁻¹ and 3 ± 6kg.vessel⁻¹.day⁻¹, respectively. These vessels specifically target longfin tuna when they are in abundance. Since the start of the tuna baitboat fishery in 1995, there has been a substantial increase in the number of new entrants. In 2002 this sector had a fleet size of 82 vessels with a capital value of ZAR163 million and a total employment income of ZAR58 million, employing 2 173 fishers, of which 87% were black African. The commercial tuna baitboat fleet has subsequently grown to 200 vessels and 3600 crew, with 110 active vessels fishing for a combined fleet average of 46 days per year. There are a high number of owner-operated vessels. Since 2007 the fishery's profit to cost ratio has been low due to the low abundance of tuna stocks off the coast of South Africa, which has resulted in poor catch returns, placing economic pressure on the fishery. The baitboat industry is a low-profit-margin fishery with a total net catch value worth ZAR90 million in 2009 (Feike 2010). The abundance of yellowfin tuna influences profit margins, with very high profits being made when abundance and catches are high. The large pelagic longline fishery has a total allowable effort of 43 vessels of which only 30 vessels fished during 2009, when a reported 766t of yellowfin tuna were caught, representing a total tonnage far in excess of that obtained by the combined effort of the baitboat and sport fishery. It is, however, assumed that considerable underreporting of catches takes place within this fishery, which means that the estimated total net catch value of ZAR100 million could, in fact, be much higher. Such underreporting of catches is of great concern for this fishery, as is the high bycatch of Chondricthians spp. that significantly outweighs imposed regulatory limits (DEAT 2007). The present study demonstrates the current lack of comprehensive catch and effort data for the sport, baitboat and longline fisheries as well as the serious limitations and flaws associated with current databases. Results from the present study have drawn attention to a number of high-priority research needs, as outlined below. (1) A major lack of comprehensive catch and effort data for the sport fishery, which can be rectified by focussing on obtaining more competition data, as well as high-quality catch and effort and socio-economic information, as opposed to relying on information from non-club anglers (Gartside et al. 1999, Williams 2003, Cass-Calay 2008). Acquisition of such data is relatively inexpensive: the location of organized clubs and their frequent competition meetings provide widespread coverage along the Southern African coastline. Such data acquisition efforts have the potential to provide reliable information on spatial catch trends. (2) Validation of vessel catch return data is required for commercial fisheries and on some recent data that has emerged from studies of catch rates and trends for target species, particularly in the longline fishery. In this context it should be noted that the most recent peer-reviewed publications on this exploratory fishery were published more than a decade ago (Kroese 1999, Penny and Griffiths 1999). Additional studies need to be undertaken and journal articles published on the current stock status of South African catches of yellowfin and bigeye tuna and swordfish.

(2) Validation of vessel catch return data is required for commercial fisheries and on some recent data that has emerged from studies of catch rates and trends for target species, particularly in the longline fishery. In this context it should be noted that the most recent peer-reviewed publications on this exploratory fishery were published more than a decade ago (Kroese 1999, Penny and Griffiths 1999). Additional studies need to be undertaken and journal articles published on the current stock status of South African catches of yellowfin and bigeye tuna and swordfish.

- Description: As leaders of small and medium enterprises (SMEs), strategic leaders are responsible for strategising, the approach to which is influenced by their cultural paradigm. The effects of this strategising are manifested in the day-to-day activities of these leaders. This study aims to build an understanding of the shared cultural assumptions of strategic leaders in agri-based processing SMEs and how these assumptions affect the strategising activities that are adopted when addressing critical incidents related to the internal integration and external adaptation of the SME. Using Strauss and Corbin‟s (1990) grounded theory method, this study develops a theory titled Conveniencing the Family in Business, which is induced from critical incidents. A sample of critical incidents was gathered from 44 qualitative interviews conducted with strategic leaders of various agri-based processing SMEs operating in Malawi. This study found that strategic leaders display persistent and stable pragmatic business survival mind sets, but dynamic cultural assumptions about relationships with organisation members. The cultural influence of these assumptions is manifested in two distinctive and alternative processes making up the theory of conveniencing the family in business. These are the humanising and commodifying of relationships with organisation members, and they are evident in hostile and friendly business environments, respectively. Humanising of relationships with all members of the organisation builds and capitalises on inclusive, organisation-wide social capital that secures the future of the business. On the other hand, commodifying of relationships with non-family organisation members weakens collective support, which becomes mainly dependent on family and friendship ties. Thus, commodifying of relationships serves to perpetuate the close integration of business activity and family requirements to ultimately convenience the family in business, and represents the desired modus operandi of strategic leaders. As strategic leaders of SMEs have not yet conceptualised this, providing them with the conceptual theory developed here may be helpful towards a consistent re-orientation of the internal organisational support in a way that does not exclude but rather harnesses the wider solidarity of organisation members. The process explained by this theory is iterative, dynamic and distinguishes patterns of relationships amongst organisation members, which either enhances or compromises their collective support for the leaders and the enterprise. This by implication affects the performance of the enterprise. The results of this study are discussed from the perspective of social exchange and social capital theory, thereby contributing to the understanding of the strategising activities of strategic leaders, as well as the processes of building or destroying social capital in this type of enterprise.

- Description: The cooperative defensive behaviour of mixed-species colonies of honeybees, Apis cerana and Apis mellifera, were tested against a predatory wasp, Vespa velutina. When vespine wasps hawk honeybees at their nest entrances, the difference in the numbers of bees involved in heat-balling among pure species and mixed-species colonies was not significantly different. However, in the mixed colonies, the numbers of A. cerana and A. mellifera workers involved in heat-balling were significantly different. The duration of heat-balling among these three groups was significantly different. During heat-balling, guard bees of both species in mixed colonies raised their thoracic temperatures and the core temperatures of the heat-balls were about 45°C, which is not significantly different from that of the pure species. These results suggest that the two species of honeybees can cooperate in joint heat-balling against the wasps, but A. cerana was more assertive in such defence.

- Description: This thesis deals with the way in which copyright law is changing in the digital environment and the mechanisms which are facilitating this change. It deals with these issues by analysing the mechanisms of this change, specifically Digital Rights Management (DRM)Systems and anti-circumvention legislation, and the impact which this change is having on the rights of copyright users. The purpose of copyright is to provide an incentive to authors to continue creating while simultaneously providing a public good in allowing the public to use those creations in certain ways. Copyright achieves this purpose by granting both the author and user certain rights. The author is given a limited monopoly over their work in exchange for allowing this work to enter the public sphere and ensuring that users of that work can utilise that work in certain limited ways. The success of copyright thus rests on maintaining the balance between the rights of these parties. The rise of digital technology has created a situation in which copyright content can be easily copied by any party with a Personal Computer and disseminated around the globe instantly via the Internet. In response to these dangers, copyright owners are making use of DRM systems to protect content. DRM systems include various measures of control within its scope. Theses systems allow for copyright owners to control both access and use of content by copyright users. DRM Systems are not foolproof measures of protection however. Technologically sophisticated users are able to circumvent these protection measures. Thus, in order to protect DRM Systems from circumvention, anti-circumvention legislation has been proposed through international treaties and adopted in many countries. The combined effect of these protection measures are open to abuse by copyright owners and serve to curtail the limited rights of copyright users. The end result of this is that the balance which copyright law was created to maintain is disrupted and copyright law no longer fulfils its purpose. This thesis undertakes an analysis of these issues with reference to how these issues affect copyright users in developing countries. This is done with particular reference to possible approaches to this issue in South Africa as South Africa is a signatory to these anti-circumvention treaties.

- Description: One of the key recommendations of the Communication Task Team Report which analysed the communication programme of government post 1994 was that of the introduction of a single corporate identity programme for government. It is against this background that various South African government departments (national and provincial) including the Eastern Cape Department of Social Development introduced their corporate identity programmes. Based on the Rotterdam Organisation Identification Test (ROIT) (van Riel et al., 1994), the paper analyses the levels to which employees identify with the corporate identity of the Department of Social Development. The ROIT scale identifies four variables that impact on employee identification which are; employee communication, job satisfaction, corporate culture and perceived organisational prestige.

- Description: In view of the important role small and medium-sized enterprises (SMEs) universally play as the backbone of national economies and the survival and competitiveness challenges that they face, the purpose of this study was to develop specific models of corporate social responsibility (CSR) for SMEs in Uganda as an avenue to enhance their competitiveness and foster economic development. The primary objective was to gain insight into the deployment of CSR in SMEs, including investigating CSR factors and their potential impact on competitiveness. This study integrates previous findings and theories on CSR activities and SMEs‟ competitiveness into a comprehensive hypothesised model. A comprehensive literature study revealed potential factors that could influence the Increased competitiveness of SMEs in Uganda. Four independent variables (Workforce-oriented, Society-oriented, Market-oriented and Environmental-oriented CSR activities) and three mediating variables (Employee satisfaction, Business reputation and Customer loyalty) were identified as variables influencing the Increased competitiveness (dependent variable) of SMEs. Independent variables were categorised as CSR factors while mediating and dependent variables were categorised as outcomes factors. Furthermore, hypotheses were formulated for possible relationships between the independent, mediating and dependent variables. All the variables in the study were clearly defined and operationalised. Reliable and valid items sourced from various measuring instruments used in other similar studies, were used in the operationalisation of these variables. Furthermore, several items were generated from secondary sources. A structured self-administered questionnaire was made available to respondents identified using the stratified and purposive sampling techniques, and the data collected from 383 usable questionnaires was subjected to several statistical analyses. The validity and reliability of the measuring instrument was ascertained using an exploratory factor analysis and Cronbach-alpha coefficients respectively. An exploratory factor analysis using SPSS 18 for Windows was conducted to identify the unique factors available in the data before applying structural equation modelling (SEM). The data were categorised into models of independent variables (CSR factors) and the mediating variables (Outcomes factors). The items measuring Market-oriented CSR activities and Workforce-oriented CSR activities loaded as expected. The items measuring Environmental-oriented CSR activities loaded onto two separate factors which were renamed Environmental-oriented CSR activities and Regulated CSR activities. One of the items originally expected to measure the construct Society-oriented CSR activities loaded onto Environmental-oriented CSR activities, leaving three items which loaded together onto the Society-oriented CSR activities factor. Four factors constituted the outcomes submodel, namely Customer loyalty, Stakeholder trust, Business reputation, and Employee satisfaction. In this study, SEM was the main statistical procedure used to test the significance of the relationships hypothesised between the various independent and dependent variables. Owing to the sample size limitations, the hypothesised model could not be subjected to SEM as a whole. Consequently, six sub-models were identified and subjected to further analysis. The following independent variables were identified as influencing the dependent variables in this study: Workforce-oriented CSR activities, Society-oriented CSR activities, Market-oriented CSR activities, Environmental-oriented CSR activities, Regulated CSR activities. To establish the influence of the various demographic variables on the mediating and dependent variables, an Analysis of Variance (ANOVA) and Multiple Linear Regression (MLR) analysis were conducted. The respondent‟s position/title in the business, form of enterprise, branch/sector of business, level of education, and the size of business were found to have an influence on the mediating and dependent variables of this study. This study has therefore added to the underdeveloped body of business research in Uganda by investigating a particularly limited segment of the literature, namely SMEs. The study has also identified and developed various models that explain the most significant CSR factors that influence the competitiveness of SMEs. Consequently, this study has put forward several recommendations and suggestions that can enhance the competitiveness of SMEs locally and globally. Further research is encouraged on action-oriented areas such as: the success of different policies and techniques to increase the uptake of CSR amongst SMEs; the economic, social and environmental impact of CSR at sector level; and a typology of SMEs with regard to their engagement in CSR.
