- Description: Bullying appears to be a worldwide phenomenon. It occurs within schools, homes, and in the community too. Bullying is a form of aggressive behaviour. Female bullying is not so easily noticed, as girls hardly ever use physical forms of aggression. Bullying can have a detrimental effect on the mental health of the victim. The victims of bullying experience symptoms of mental discomfort, which include low self esteem, feelings of helplessness, feelings of worthlessness and inferiority, lack of confidence, isolation, self-conscientiousness; and lastly, this can lead to suicide. Some form of intervention is necessary to provide adolescents with skills to combat bullying and help them to become mentally healthy again. The overall goal of the study was to develop, implement and evaluate a psycho-educational programme for female adolescents in a secondary school setting, in order to assist them in coping with bullying. The objectives of the research study were to: Conduct asituational analysis to identify the mental health needs of adolescent girls, as victimsof bullying. Develop a psycho-educational programme to facilitate the promotion of mental health of those adolescent girls who are victims of bullying. Implement the psycho-educational programme to facilitate coping by adolescent girls who are victims of bullying. Assess whether the adolescent girls have benefitted from attending the psycho-educational programme. The researcher used a qualitative, explorative, descriptive and contextual design. The research methodology consisted of four phases. In phase one of the research, a situational analysis was done; and the characteristics of mental discomfort exhibited by the victim were identified. The needs of the adolescent girl who has been bullied have already been described. Phase two involved the development of a psycho-educational programme. The information from the situational analysis was used to develop the conceptual framework. The six concepts in the survey list of Dickoff et al. (1968:422) were described as follows: the recipient is the adolescent girl who has been bullied, the agent is an advanced psychiatric nurse, the context is the community and the secondary school where bullying takes place, the dynamics of the intervention constitute the mental discomfort experienced by the adolescent girl. This is what motivates her to participate in the programme. The procedure was identified as the psycho-educational programme, while the terminus or outcome of the intervention for the adolescent girl would be for her to experience mental health after being exposed to the psycho-educational programme. The relationship between the concepts was used to form the mind map of the conceptual framework. This guided the development of the psycho-educational programme. The content of the programme has already been described. In phase three the psycho-educational programme is implemented and in phase four the programme is evaluated. The psycho-educational programme taught the teenage girls skills and it provided them with knowledge to cope better with the bullying. Attending the programme made the teenagers aware that they needed to change to experience mental health and happiness. The empirical study took place in phase four. The data-gathering method in phase four included the conducting of semi-structured interviews with the adolescent girls who participated in the programme, as well as the teachers of these adolescent girls and their parents. Naïve sketches, reflective journals, observations made and field notes formed part of this database. The data was analyzed by means of Tesch‟s descriptive analysis (in Creswell, 2003:192). The participants had to comment on how they were coping after the implementation of the psycho-educational programme. In conclusion, an intervention in the form of the psycho-educational programme was shown to be beneficial to adolescent girls who were victims of bullying, to assist them in coping with the aftermath of being bullied. Recommendations were made to enhance nursing practice, as well as nursing education and nursing research. Keywords: Adolescent girls, bullying, secondary schools, advanced psychiatric nurse, psycho-educational programme, mental health.

A psychobiographical study of John Winston Lennon

- Description: Psychobiography can be viewed as the re-writing of an individual’s life story previously undetected. In general it consists of a combination of two central elements: biography and psychological theory that aim to explain the particular individual’s psychological development. This particular study serves to explore the extraordinary life of renowned singer, songwriter, artist and activist, John Winston Lennon (1940-1980). The basis for this investigation will take the form of notable biographical accounts of the subject’s life, together with Austrian psychiatrist Alfred Adler’s (1938) theory of Individual Psychology, which recognizes the importance of human society for the development of individual character and the orientation of every single action and emotion in the life of a human being. Adler’s theory further explores that the main motives of human thought and behaviour are an individual’s striving for superiority and power, partly in compensation for his feeling of inferiority. The psychobiographical data collection and analysis for this research thesis will be guided by Yin’s (1994) theory of ‘analytic generalisation’, which uses a theoretical framework in selecting relevant data which develops a matrix as a descriptive framework for organizing and integrating that data, and Alexander’s (1988) analytical model which focuses on lifting out themes through principal identifiers of salience was used and applied. John Winston Lennon expressed his personal experiences and ideals through his songs and became the spokesman for his generation on modern day issues such as feminism and world peace. It is however, unfortunate that Lennon throughout his life remained a boy who felt rejected and unloved by his parents and strove to be superior in all aspects of his rich life in an attempt to acquire the love and acceptance that was not bestowed on him as a child.

A psychobiography of Friedrich Nietzsche
- Authors: Booysen, Duane Danny-Coe

- Subjects: Nietzsche, Friedrich Wilhelm, 1844-1900 , Philosophers -- Germany -- Biography

- Description: The primary aim of this psychobiography was to examine Friedrich Nietzsche’s life by utilizing Carl Rogers’ theory of the fully functioning person. Friedrich Nietzsche (1844 - 1900) has become an iconic figure in German philosophy and literature. Nietzsche’s criticism of western morality and culture led him to believe that humankind was not living to its highest potential and consequently Nietzsche sought after a life of self-becoming. Nietzsche’s philosophy has influenced various people such as Viktor Frankl, DH Lawrence, Michel Foucault and NP van Wyk Louw. Nietzsche was chosen as the research subject because of personal interest, his prominence as a philosopher, and because of his ambition to live a meaningful life. Psychobiographical research with the use of psychological theory allows for the exploration and description of the life of an individual. This significant area of research involving the application of psychological theory has in previous decades, however, been under-utilized, particularly in South Africa. But more recently, has it been receiving increasing support by researchers both internationally and in South Africa. Data collected on Friedrich Nietzsche’s life were drawn from several primary and secondary sources. A data collection and analysis grid was developed in order to collect data systematically, and to analyse the data according to the qualities of Carl Rogers’ theory. The study adds to the body of psychobiographical research. It also provides an empirical exploration of Carl Rogers’ theory of the fully functioning person. As the scope of the study was that of a master’s dissertation, future research, utilising semi-structured interviews with knowledgeable relatives, academics, psychologists, biographers, philosophers and historians on Nietzsche’s life, could extend this line of research. In conclusion, the current psychobiography suggests that Nietzsche lived a life filled with several personal crises. Despite these challenges, Nietzsche directed himself towards living as a fully functioning person. Nietzsche’s impetus towards self-becoming is also evident within his philosophical writings. Nietzsche was an extraordinary individual whose life, as described in the current psychobiography, corresponds closely to Rogers’ (1961) theory of a fully functioning person.

- Description: Rural schools have a pressing need for ICT and Internet services, for them-selves and the surrounding communities. Educators can play a crucial role of fulfilling this need. But how ready are schools, educators and communi-ties to engage with ICT and use it for their empowerment? This paper re-ports the findings of an e-readiness assessment and promotion drive by re-searchers from the Siyakhula Living Lab in parts of the Mbashe Municipali-ty, in South Africa. The Siyakhula Living Lab is a multi-disciplinary, multi-year initiative to foster grassroots innovation in marginalized communities with the aim of improving their lives and economies. The drive was con-ducted to support the expansion of the network of Digital Access Nodes, ie ICT points-of-presence of the Living Lab in the community: this network rep-resents the structural backbone on which all other activities rest. The as-sessment shows that, while the practical difficulties are many, the communi-ties are very eager to engage with ICT and understand fairly well the con-nection between ICT availability and the possibility of improvement in their life conditions.

- Description: In recent years, there has been increasing concern that gender bias has prevented women from advancing as rapidly and as frequently as men into management positions. Although the number of women managers has increased, they may experience difficulty moving into upper management positions. The purpose of our research was to study employee gender perception of key variables of women and the positions held in high technology companies. In this research, phenomenological research method was chosen, because the aim of it is to determine what the experience means for the people who have experienced it. Based on the collected data, answers and experiences, structural analysis was done in order to find out the major phenomena of gender perceptions. A number of variables uncover the perception of aspects of policy and gender and barriers that may affect female employees' opportunities for advancement. Using a sample of 30 full-time employees from Company A, the results indicated that position held was significantly different for male and female employees. The results also indicated that neither male nor female employees appeared to notice the apparent perceptions apparently as a glass ceiling within their company and the Implications discussed and recommendations provided. With reference to the Empirical research, this paper increases the knowledge about women’s career development and provides recommendations how to deal with it. It is also expected that this thesis will be helpful to all women who are in the labour market for their career development and advancement.

- Description: [from the introduction] Water lettuce, Pistia stratiotes L. (Araceae) is recognized as being among the world’s worst aquatic weeds. In its adventive range, the plant forms extensive mats capable of blocking navigation channels, impeding water flow in irrigation and flood control canals, and disrupting hydropower generation (Holm et al. 1977). Dense mats of the weed prevent light penetration into the water column which negatively affects submerged aquatic plant communities, causing a lowering of the oxygen concentration and thereby reducing benthic invertebrate and fish populations (Neuenschwander et al. 2009).

- Description: This paper presents the results of a review process that sought to disen-tangle the different ways in which social learning is conceptualised in nat-ural resource management. We begin with an historical review that seeks to reveal the roots of social learning theory in natural resource manage-ment. Based on this analysis, we develop typologies of statements about the processes that support social learning, and the outcomes of these processes. We then conduct a systematic review of the literature to as-sess the extent to which there is an emerging consensus around these typologies. We conclude that a key source of the confusion currently prevalent in the literature, stems from the fact that the same term is used to refer to quite different processes, which have different outcomes as their goal. To find our way out of the current confusion in the literature, researchers must be explicit about the definitions that they adopt for so-cial learning, and locate these definitions within the historical develop-ment of thinking around social learning in this field. Active debate about appropriate definitions for social learning, based on empirical studies and experience, should form the basis of this field of research in the coming years.

We conclude that a key source of the confusion currently prevalent in the literature, stems from the fact that the same term is used to refer to quite different processes, which have different outcomes as their goal. To find our way out of the current confusion in the literature, researchers must be explicit about the definitions that they adopt for so-cial learning, and locate these definitions within the historical develop-ment of thinking around social learning in this field. Active debate about appropriate definitions for social learning, based on empirical studies and experience, should form the basis of this field of research in the coming years.

- Description: This dissertation is a self-reflexive study into effective translation strategies. The study focuses primarily on the translation strategies by Vinay and Darbelnet (1995), namely direct and oblique strategies of translation. The strategies are used in the translation of Jeanne Goosen‘s novel Louoond (1987). The novel was chosen on account of the writer‘s unique writing style and the challenges it poses for the prospective translator. One of the key objectives of this study was to comprehensively illustrate Vinay and Darbelnet‘s strategies of translation when translating the novel. The theoretical framework of this study is an analysis of Vinay and Darbelnet‘s translation strategies. The study also aims to give insight into what is meant by translation, translation theory, literary theory and literary translation. The translation of the novel is the final product, but in order to illustrate each procedure of Vinay and Darbelnet (1995) examples were taken from this final product. The chapters that follow illustrate the strategies of Vinay and Darbelnet (1995) as used in the translation of an Afrikaans text (SL) into English (TL). Conclusions can then be drawn as to whether full equivalence was obtained and whether the translation is deemed successful.

- Description: The South African government cannot in isolation deliver all the community needs as expected. Therefore, the involvement of all the sectors becomes crucial in the fight against poverty, largely due to the fact that the delivery of services (community needs) by the public sector does not balance with the amount of the resources allocated. This implies that government cannot successfully manage to deliver the community needs in isolation. A shared service delivery strategy to support the socio-economic development initiatives towards sustainable shared growth is therefore essential. The Public-Private Partnerships and Public-Public Partnership have emerged as alternative measures or important public policy tools in addressing the ‘shared delivery’ of services to the general public of South Africa. As a result of high levels of poverty experienced by the people of the Eastern Cape, in fact by the larger South African population, major interventions by NGOs, CBOs and other civil organisation are gaining momentum. Likewise, the establishment of the National Development Agency as mandated is also a public policy tool that looks into improving the socio-economic development of the local communities. Such interventions and partnerships therefore have a big role to play in support of the ANC led government to effectively deliver on its mandate, thus ensuring improved citizen’s welfare. Importantly, what triggered the undertaking of this study are the high levels of poverty, poor local economic developments and poor monitoring and evaluation of the funded projects in the Eastern Cape. In this study community and poverty in developing South Africa is well discussed. Attention is drawn to the whole idea of socio-economic development - simultaneously touching on the socio-economic shift in SA. Local Economic Development is also discussed with its LED dimensions, including business developments within the two said districts. The main aim of this study is to establish the extent to which the interventions by National Development Agency ‘Public Entity’ have improved the socio-economic development of the rural local communities in the Amathole and OR Tambo Districts towards sustainable and shared growth. The study includes a conceptual meaning of the public sector in general with its key service delivery role players. The study also includes the conceptual theoretical basis of the socio-economic development with specific reference to South Africa then cascades down to the study areas. Under the same note, a detailed explanation is also given on the nature of Public-Private Partnership (PPP) as a model for improved socio-economic development. Conceptual presentation of the Public-Public Partnership (PPP) for shared service delivery is also alluded to.

- Description: Massively multiplayer online role-playing games are growing in popularity with millions of people participating in these persistent online environments on a daily basis. Accompanying the ever-increasing subscription numbers is an increase in real money trade transactions stemming from these game worlds. The research question to be addressed in this thesis is whether transactions stemming from virtual worlds have real-world taxation consequences. The goal of this research is to determine the taxability of virtual assets obtained in structured as well as unstructured virtual environments and to attempt to establish the differences between capital and revenue receipts in these virtual realms, taking into account the nature of a receipt. The general deduction formula is applied to establish the deductibility of expenditure incurred whilst participating in these virtual environments. Sundry matters such as Value-Added Tax, donations tax, the withholding tax on gambling gains and tax avoidance will also be addressed. The methodology adopted for the research could best be described as interpretative, aimed at analysing and interpreting the relationship between real world taxes and persistent virtual worlds and the transactions that stem from participation therein. The research is based purely on documentary evidence. After applying relevant tax legislation to virtual economies it became evident that merely because virtual assets only exist in virtual reality does not necessarily preclude them real world tax consequences. It was concluded, however, that it is not practical for the South African Revenue Service to monitor all virtual world transactions or for participant taxpayers to calculate the real world value of each and every asset acquired in-world. As a result, it was concluded that real world tax consequences should only be applied in situations where participants actually convert their virtual assets into real world currency.

- Description: Thicket degradation within the Addo Elephant National Park (AENP), Eastern Cape, South Africa is a key issue of concern. The increasing elephant densities have over time threatened thicket vegetation, which is endemic to this area. The “elephant problem” within the Park has raised many concerns as to the vulnerability of thicket to elephant impacts. Remote sensing provides an environment in which temporal changes in thicket vegetation condition can be assessed. The main aim of this study was to assess temporal and spatial trends in thicket degradation within the AENP, using multi-temporal satellite imagery. Elephant induced thicket degradation was assessed using multi-temporal satellite imagery from between 1973 and 2010. Changes in thicket condition in relation to the AENP expansion were analysed using the Normalized Difference Vegetation Index (NDVI), post-classification and landscape metrics. The ‘per-pixel’ based classification approach was carried out and change detection of land cover classes was analysed by post-classification. Landscape spatial metrics were used in order to gain an understanding of vegetation fragmentation trends. Temporal changes in vegetation gradients in relation to water points and thicket condition within the botanical reserves were also assessed. Thicket condition was noted to deteriorate as the AENP expanded. An expansion of degraded vegetation away from the water points was identified during the study period. Thicket condition in botanical reserves 1 and 2 fluctuated over time, with a registered increase in intact thicket within botanical reserve 2, with botanical reserve 3 remaining constant. Landscape spatial metric analyses revealed evidence of increased vegetation fragmentation as new areas of the AENP were opened for elephant activity. A progressive decline in intact thicket and increase in degraded thicket were observed. Considering the current elephant densities, thicket degradation within AENP is set to continue, causing a continued threat to the thicket biome.

- Description: The majority of South Africa’s fresh water (lotic and lentic), is eutrophic and this has resulted in water hyacinth, Eichhornia crassipes (C.Mart.) Solms. (Pontederiaceae) becoming South Africa’s most damaging aquatic macrophyte. Recently however, concerns have also been voiced over the presence of highly invasive submerged macrophyte species, such as Eurasian water-milfoil, Myriophyllum spicatum L. (Haloragaceae) in the Vaal River. Interaction studies between floating and submerged macrophytes have shown that floating macrophyte dominance restricts light penetration into the water column shading out submerged macrophytes while submerged macrophyte dominance reduces nutrient availability in the water column limiting floating macrophyte growth. This cycle ensures that these species cannot coexist in the same habitat for extended periods of time. The aims of this thesis were to: 1. Investigate changes in the historical and current macrophyte dominance in the Vaal River 2. Determine whether these changes could be attributed to stochastic events, such as floods and herbicide control measures. 3. The physio-chemical conditions of the water column, and whether pressure from herbivory by macroinvertebrates had possibly influenced Eurasian water-milfoil’s ability to dominate. Spatial and temporal analysis of satellite imagery revealed that water hyacinth and submerged macrophyte species dominated different regions of the study area over different periods of time from 2006 to 2010. This was significantly correlated with nitrate concentrations of the water column. One of the lower Vaal River Water Management Areas (WMA) had changed from a water hyacinth dominated state in 2006 to an alternative submerged macrophyte dominated stable state in 2008. It was concluded that this change could be attributed to: a stochastic flooding event in 2006; perturbation from integrated control measures implemented against water hyacinth; and low nitrate concentrations of the WMA. The lack of any substantial macroinvertebrate herbivory pressure or control measures implemented against Eurasian water-milfoil, compared to similar surveys conducted in the U.S.A. and its native range in Eurasia was shown to contribute to its dominance. Future successful integrated control programmes, including biological control against Eurasian water-milfoil, could provide the perturbation required to restore the ecosystem. However, without the reduction in nitrate concentration levels, water hyacinth will remain the dominant stable state of the rest of the Vaal River.

- Description: The Internet Protocol Multimedia Subsystem (IMS) is a component of the 3G mobile network that has been specified by standards development organisations such as the 3GPP (3rd Generation Partnership Project) and ETSI (European Telecommunication Standards Institute). IMS seeks to guarantee that the telecommunication network of the future provides subscribers with seamless access to services across disparate networks. In order to achieve this, it defines a service architecture that hosts application servers that provide subscribers with value added services. Typically, an application server bundles all the functionality it needs to execute the services it delivers, however this view is currently being challenged. It is now thought that services should be synthesised from simple building blocks called service capabilities. This decomposition would facilitate the re-use of service capabilities across multiple services and would support the creation of new services that could not have originally been conceived. The shift from monolithic services to those built from service capabilities poses a challenge to the current service model in IMS. To accommodate this, the 3GPP has defined an entity known as a service capability interaction manager (SCIM) that would be responsible for managing the interactions between service capabilities in order to realise complex services. Some of these interactions could potentially lead to undesirable results, which the SCIM must work to avoid. As an added requirement, it is believed that the network should allow policies to be applied to network services which the SCIM should be responsible for enforcing. At the time of writing, the functional and structural architecture of the SCIM has not yet been standardised. This thesis explores the current serv ice architecture of the IMS in detail. Proposals that address the structure and functions of the SCIM are carefully compared and contrasted. This investigation leads to the presentation of key aspects of the SCIM, and provides solutions that explain how it should interact with service capabilities, manage undesirable interactions and factor user and network operator policies into its execution model. A modified design of the IMS service layer that embeds the SCIM is subsequently presented and described. The design uses existing IMS protocols and requires no change in the behaviour of the standard IMS entities. In order to develop a testbed for experimental verification of the design, the identification of suitable software platforms was required. This thesis presents some of the most popular platforms currently used by developers such as the Open IMS Core and OpenSER, as well as an open source, Java-based, multimedia communication platform called Mobicents. As a precursor to the development of the SCIM, a converged multimedia service is presented that describes how a video streaming application that is leveraged by a web portal was implemented for an IMS testbed using Mobicents components. The Mobicents SIP Servlets container was subsequently used to model an initial prototype of the SCIM, using a mUlti-component telephony service to illustrate the proposed service execution model. The design focuses on SIP-based services only, but should also work for other types of IMS application servers as well.

- Description: This research adds on to Chaulk & Brown (2008) research on the assessment of employees’ reaction towards management and the union in the pre-strike and post-strike period. Research problem: The study raised two aspects that form part of the statement of the problem. Firstly, strike action has been a major aspect describing the South African industrial relations climate. The high level of strike action prompts the question; “Are South Africans World Class Strikers?” (Anstey, 2006). Secondly, the analysis of strike action has focussed more on the economic and power testing impact analysis rather than psychological and affective impact analysis of the strike such as establishing the impact of the strike on job satisfaction, work climate satisfaction, organisational commitment, management satisfaction, and union commitment. Research objectives: To address the research problem, research objectives, research questions and hypotheses were established. The main objective of the study was to examine the causes, processes and the impact of the strike, thereby making a contribution to both theory and practice. Whereas the contribution to theory took a form of building on to the research carried out by Chaulk & Brown (2008), and exploring through the process analysis on how behaviour during the conflict impacts on the ongoing relationships within the organisation, the contribution to practice took a form of highlighting to management and unions the impact of the strike on employees so that necessary interventions to prevent the negative impact of the strike would be created. Research questions: Six research questions were established and these were; what were the causes of the strike; how did the strike unfold; what were the substantive outcomes of the strike; what were the procedural outcomes of the strike; what were the climate outcomes of the strike; is there a relationship between the demographic factors and the affective outcomes of the strike? Research hypotheses; Five research hypotheses were established for the research. These hypotheses were aimed at establishing the impact of the strike on the affective outcomes of the strike. These were; there was a significant change in the level of organizational commitment after the strike; there was a significant change in the level of job satisfaction after the strike; there was a significant change in the level of work climate satisfaction after the strike; there was a significant change in the level of management satisfaction after the strike; and there is was significant change in the level of union commitment after the strike. Research design and methodology: Both qualitative and quantitative methods were used to collect data. Qualitatively, interviews, media reports and the Municipality records were being used to collect data on the causes, processes and outcomes of the strike. Quantitatively a survey questionnaire was used to collect data. Data was collected from 105 Traffic Officers who had recently been on strike in the NMBM. Measures of organisational and union commitment, employee job satisfaction, and work climate satisfaction were assessed using the Chaulk & Brown (2008) questionnaire. A paired sample t-test, ANOVA test, and Scheffe test and Cronbach’s alpha, were some of the quantitative methods used in data analysis. Henning’s approach was used to analyze qualitative data. Major findings: The results from the questionnaire revealed that job satisfaction, work climate satisfaction and management satisfaction significantly changed in the post-strike period. In addition, impact of demographic factors on affective factors was evident for participation in the strike and the level of union commitment; age and job satisfaction; occupational level and job satisfaction; and service length and union commitment.

- Description: This research adds on to Chaulk & Brown (2008) research on the assessment of employees’ reaction towards management and the union in the pre-strike and post-strike period. Research problem: The study raised two aspects that form part of the statement of the problem. Firstly, strike action has been a major aspect describing the South African industrial relations climate. The high level of strike action prompts the question; “Are South Africans World Class Strikers?” (Anstey, 2006). Secondly, the analysis of strike action has focussed more on the economic and power testing impact analysis rather than psychological and affective impact analysis of the strike such as establishing the impact of the strike on job satisfaction, work climate satisfaction, organisational commitment, management satisfaction, and union commitment. Research objectives: To address the research problem, research objectives, research questions and hypotheses were established. The main objective of the study was to examine the causes, processes and the impact of the strike, thereby making a contribution to both theory and practice.

- Description: The study sought to investigate factors influencing curriculum management in Bizana schools. A survey design which used mainly qualitative aspects of research was used in the study. Questionnaires and interview schedules were used to collect data. Participants (N=60) were made up of 10 learners,10 teachers, 10 School Management Team members ( SMTs), 10 parents and 20 district officials. The teachers, learners, parents and SMTs including principals were selected from 3 schools being a Primary School, a Junior Secondary School and a Senior Secondary School. Frequency tables were used to present quantitative data while verbal quotes were presented in support of themes that emerged from the qualitative data. The findings of the study revealed that the following factors were regarded as the causes of poor curriculum management; lack of training and skills on the part of curriculum managers, un-availability of resources in schools, the level of parental involvement in curriculum and regular systemic changes. It was recommended that the Department of Education should ensure that all curriculum managers are being trained to provide them with enough skills. The Department of Education should also supply schools with adequate resources. Parents should also be trained on curriculum issues. Too many changes in the system within a short space of time should be avoided.

- Description: The problem of indiscipline in schools has attracted the growing attention of researchers in South Africa and the world at large. Learner indiscipline has been variously reflected in behaviours which range from serious ones such as drug abuse, assault, theft, rape and murder, to minor ones such as truancy; all of which negatively affect teaching and learning. While there is agreement on the need to address the problem, there is a great deal of contestation around what strategies and practices are appropriate to instil discipline in schools. Within this debate many countries, including South Africa, have decided to move away from punitive approaches such as corporal punishment and replace them with what is called Alternatives to Corporal Punishment (ATCP). The main aim of this study was to interrogate the consistency that prevails between disciplinary practices and principles of alternatives to corporal punishment and the implications of this for school leadership. A mixed method design was used. The study was conducted in two phases: the first was a survey during which trends in disciplinary practices were established; the second was a multiple case study where in-depth interviews were conducted in five primary schools across different contexts which included farm, suburban, township, rural and informal settlement locations. This study has seven main findings. First, it was found that primary schools in the Buffalo City Metropolitan Municipality experienced minor offenses which clustered around levels 1 and 2 of the ATCP classification. Second, although statistically there was a weak negative correlation (r = - 0.11) between location and behaviour which is not significant (p >. 05) or (p = .46), qualitative evidence suggests a relationship between context and disciplinary offences. Third, principals’ roles in instilling discipline were focused mainly on reactive administrative and management functions rather than on giving leadership designed to inspire alternative ways of behaving. Fourth, principals’ and teachers’ belief in the use of alternatives to corporal punishment revealed ambivalence and lack of understanding. Fifth, measures to instil discipline, even though they were said to be based on alternatives to corporal punishment, placed heavy emphasis on inflicting pain and relied on extrinsic control. Sixth, two disciplinary measures designed to inflict pain were found to be weakly associated, but significantly (p < 0.05) with violent behaviour, lending credence to view that in using certain practices to instil discipline there are socialisation consequences. Finally, the use of some measures recommended by alternatives to corporal punishment yielded some unintended socialisation consequences. The study concludes that there was lack of consistency between disciplinary practices in Buffalo City Metropolitan Municipality primary schools and the principles of Alternatives to Corporal Punishment. The findings suggest that it is difficult to achieve the consistency without a school leadership which understands that the alternatives call for a paradigm shift in measures to instil discipline. For improving discipline in schools, it is recommended that school principals and stakeholders must focus on measures that are meant to cultivate a new school culture guided by values of self-discipline in order to minimise the need for extrinsic punitive control. For further research, a follow up study based on a probability sample, which should include secondary schools, could be undertaken in order that results can be generalised.
