- Description: This thesis investigates the current legislation and police protocols set in South Africa, specifically regarding their adequacy in protecting the country’s children from sexual abuse. It focuses on relevant legislative provisions and protocols, on sexual abuse of children and on an empirical study conducted amongst a variety of officials who represent the South African legislation at different levels. Trends, developments and problems are analysed and brought forward to raise an awareness on the severity of the issue of child sexual abuse. In addition, this thesis explores how the diversity within the community of Grahamstown, South Africa, should be considered to a higher degree in the legislation. There is a clear indication of a prevalent patriarchal hierarchy within the community which, in reality, makes women and children more vulnerable to sexual abuse. The methods used in this thesis involves purposive sampling, which led to one on one interviews between the researcher and participant. Thisthesis concludes with confirmation of the hypothesis whereby the South African legislation is not adequately protecting the rights of children in regards to sexual abuse. However, to fully adapt the legislation and make it as versatile and as effective the State hopes it to be, it is necessary to understand the society’s perception on women and children and to rectify it. As difficult as this may sound, it all begins with a strong and influential government.

- Description: This thesis investigates the nature and strength of the relationship between short-, medium-, and long-term real interest rates and capital investment spending at both the aggregate and disaggregate levels in South Africa in order to determine whether changes in the real interest rate affect the level of capital investment in the economy. This thesis used quarterly data for the period 1987 to 2013. VAR modelling, variance decompositions, impulse response functions and Granger causality tests are used to explore the nature and strength of the relationship between interest rates and investment spending. It is found that interest rates explain very little of the variation in investment spending and seem to have little impact on investment (of any type). Furthermore, short-, medium- and long-term interest rates have different effects on the level of investment spending. A rise in short-term interest rates appears to decrease the level of investment spending in the long-run, whereas a rise in long-term interest rates results in an increase in investment.

- Description: Introduction: Hamstring injury prevalence in soccer remains a major concern. Research in this context has focused on Caucasian populations with little attention given to other ethnic groups. The compatibility and applicability of such research to the South African context, particularly at an amateur level, may be minimal due to fundamental differences in physical characteristics, as well as complexities with regards to implementation. The aim of this investigation was therefore twofold. 1) Identify the lower extremity strength and performance profile of Peri-urban Amateur South African Players, and 2) Assess the efficacy of a community based intervention through the use of the Nordic Hamstring Exercise. Methods: 19 Black male Eastern Cape amateur players participated in a 12 week randomly controlled trial (9 = Control, 10 = Intervention). All participants completed regular training, while the intervention group, in addition, performed the Nordic Hamstring exercise post warm up. The incremental program design was taken from Mjolsnes et al. (2004), with a progressive increase in both sets and repetitions. Compliance was defined as completion of the required exercises for that session. Isokinetic strength evaluations (at 60°.s-1 and 180°.s-1) including assessment of peak torque and total work, as well as performance measures of countermovement and squat jump, were completed pre and post intervention, with the profile of the Peri-urban player the combined responses of both groups at baseline. Additionally, both the functional ratio (Eccentric Hamstrings/Concentric Quadriceps) and eccentric utilization ratio (Countermovement Jump/Squat Jump) were calculated. Results: Concentric quadriceps peak torque at baseline reported values of 195 (±22) Nm and 141 (±21) Nm at 60°.s-1 and 180°.s-1. Values of 162 (±21) Nm were observed for peak torque of the eccentric hamstrings at 60°.s-1, while 157 (±18) Nm was indicated at 180°.s-1. Mean functional ratio responses were observed as 0.83 (±0.11) and 1.12 (±0.16) for 60°.s-1 and 180°.s-1 respectively. Additionally, the eccentric utilization ratio responses were recorded as 1.04 (±0.08). Regarding the intervention, concentric quadriceps total work of the dominant limb significantly improved over the time course of experimentation within the intervention group. Other quadriceps variables, concentric hamstrings, squat jump capability and performance measures all reported no significant changes (p>0.05) over the course of assessment when compared to the control. Eccentric hamstrings peak torque observed significant improvements (p<0.05) of between 5.72 and 12.82 % within the intervention group, while the countermovement jump indicated a significant 15.59 % increase (p<0.05). Additionally, the functional ratio and the eccentric utilization ratio both indicated no significant changes (p>0.05), with a 2.48-7.66 % and 5.33 % improvement noted following completion of assessment. Conclusion: Isokinetic responses at baseline observed decreased quadriceps strength, and increased hamstring strength when compared to both amateur and professional populations examined in previous studies, for both isokinetic testing speeds. Additionally, performance measures indicated similar responses to other amateur populations. Regarding the intervention, significant improvements in eccentric hamstring peak torque and countermovement jump indicate the partial success of the present intervention. Additionally, while the functional ratio and eccentric utilization ratio reported no significant changes, improvements were noted within the intervention group while the control noted no change. The Nordic hamstring lower therefore resulted in strength improvements within the eccentric hamstrings, reported as a significant factor for injury risk, however, such changes were not sufficient to significantly impact the functional ratio. It can be concluded that community based programs within South Africa have the potential to be effective; however, there are many barriers to implementation, including, language, ethnic and cultural differences, while a lack of resources and infrastructure play a significant role in a lack of development. More research of this nature is required to provide scientific support for structures and guidelines for the peri-urban community based South African player, to ensure the efficacy of internationally successful interventions such as the Nordic exercise.

- Description: The Einstein-Podolsky-Rosen (EPR) thought experiment produced a problem regarding the interpretation of quantum mechanics provided for entangled systems. Although the thought experiment was reformulated mathematically in Bell's Theorem, the conclusion regarding entanglement correlations is still debated today. In an attempt to provide an explanation of how entangled systems maintain their correlations, this thesis investigates the theory of post-state teleportation as a possible interpretation of how information moves between entangled systems without resorting to nonlocal action. Post-state teleportation describes a method of communicating to the past via a quantum information channel. The resulting picture of the EPR thought experiment relied on information propagating backward from a final boundary condition to ensure all correlations were maintained. Similarities were found between this resolution of the EPR paradox and the final state solution to the black hole information paradox and the closely related firewall problem. The latter refers to an apparent conflict between unitary evaporation of a black hole and the strong subadditivity condition. The use of observer complementarity allows this solution of the black hole problem to be shown to be the same as a seemingly different solution known as “ER=EPR", where ‘ER’ refers to an Einstein-Rosen bridge or wormhole.

- Description: Substance use disorder is an intricate societal phenomenon resulting from psychological and physiological dependence. The aim of this study was to gain an in-depth understanding of the lived experiences of individuals recovering from a substance use disorder. An interpretive phenomenological method was used to elicit the fundamentals of recovery as experienced by the participants. Random purposeful sampling was used and guaranteed that appropriate participants were selected. Data was collected through the use of semi-structured, in-depth, face-to-face interviews with four individuals. The collected data was then processed according to the three interpretive phenomenological principles namely, phenomenology, hermeneutics and idiography. Analysis was thereafter conducted using five steps, which led to two main themes emerged. The two thematic categories that emerged were (1) the ex-users’ experiences of using substances and (2) experiences of recovering from a substance use disorder. Within the first thematic category two sub-themes developed which included: reasons for using substances, and when substance use became a dependency. The sub-themes that emerged in the second thematic category included: initiating recovery, recovery and treatment models, post-treatment, risk factors in recovery and supportive and protective factors in recovery.

- Description: Richards Bay Coal Terminal (RBCT) is situated in the South African deep water harbour of KwaZulu- Natal. The company provides coal mining organizations a strategic logistics link to international coal markets by enabling the use of a coal exporting facility. RBCT recognizes that its lifeblood is the human capital it retains and that achieving a competitive edge equitably and fairly through its people is a priority (du Preez, 2012). In the modern organization operating in an environment of uncertainty and constant change, employee’s commitment to the organization can be a critical determinant of its success or failure in anchoring a competitive advantage (Ulrich, 1998). The current study explored a relationship between the full range leadership styles of supervisors and the organizational commitment of the subordinates to the organization. The literature reviewed in the study includes two models; the first model is by Bass and Avolio and is referred to as the full range leadership model (FRL). This is the independent variable of the research. The dependent variable is organizational commitment, which belongs to the three component model by Meyer and Allen. These models each contain an instrument which was used on a sample of 120 non-supervisory employees. The independent variable used an instrument called the multifactor leadership questionnaire (MLQ) and the dependent used the organizational commitment questionnaire (OCQ). The data collected with these two questionnaires was then subjected to statistical scrutiny. A two-tailed Pearson correlation analysis was conducted to ascertain the strength and direction of the linear relationship, but most importantly to, at 95%-99% confidence, ascertain the statistical significance of the relationships. The findings of the study reflected no statistically significant relationships between transactional leadership and all of the three components of organizational commitment. The two components; affective and normative commitment, both reported a significant relationship with laissez-faire, whilst continuance commitment reflected insignificance. A positive significant relationship between transformational leadership and affective commitment was evident. This leadership style demonstrated no statistically significant relationship between it and continuance and normative commitment. The combined findings suggested that transactional leadership style of supervisors is somewhat unrelated to the subordinate’s need, desire and or sense of obligation to remain employed. A more transformational style of leadership appears to inspire a desire to sustain employment and affectively commit to the organization, whilst this style bears no relation to the need and sense of moral obligation of the subordinate to maintain employment. Laissez-faire reported a weak insignificant negative relationship with continuance commitment. The result suggests the independence of the subordinates’ need to maintain employment to the lack of leadership presence of the supervision. The significant relationship between laissez-faire and normative commitment may be accepted as indicative of how the absence of leadership is related to the employee’s recognition of no developmental intentions demonstrated by the supervisor. Although weak, the relationship between laissez-faire and affective commitment entails that the more prevalent the non-leadership (absence of leadership) style of the supervisor, the less desire do subordinates demonstrate to remain employed.

- Description: Background: Despite the introduction of running footwear in the 1970’s, running injury rates continue to be unacceptably high. The subsequent revival of barefoot running and the introduction of minimalist footwear occurred, in an attempt to reduce injury rates and increase performance. There is much contention in the literature around the effectiveness of these footwear conditions. Furthermore individual responses have recently been proposed to provide more accurate and reflective conclusions than the use of mean data. Objectives: Twofold: a) to compare the biomechanical, physiological and perceptual responses between the shod, minimalist and barefoot footwear conditions and b) to assess and compare individual responses under these footwear conditions. Methods: 26 well-trained, male, habitually shod endurance runners, aged between 18 - 30 years completed three experimental sessions on an indoor runway and motorized treadmill. Each session was completed in either the shod, minimalist or barefoot condition, running at 15km.h-1. Variables assessed included stride rate, stride length, impact peak, vertical impact and average loading rate and strike time (biomechanical); heart rate, oxygen consumption and electromyography (physiological); and rating of perceived exertion and body discomfort (perceptual). Results: Biomechanics – Stride rate and stride length showed a significant (p<0.001) increase and decrease respectively when running in the minimalist or barefoot conditions versus shod. Running barefoot versus the minimalist and shod conditions resulted in a significantly (p<0.001) greater vertical impact loading rate. Strike time was significantly (p=0.008) reduced running in the minimalist and barefoot conditions versus shod. Physiology – Running barefoot versus shod resulted in a significantly (p=0.02) reduced heart rate and Tibialis Anterior activity (p=0.005). There was a large variability in individual responses for many variables, with responders and non-responders seen. Conclusion: The study suggests that there are significant differences between all three forms of running for some variables. It was further noted that there is support for the proposal that individual responses are highly variable and should be analysed accordingly

- Description: In exploring the use of emotional labour among nurses within the nurse/patient relationship, this study employed the conceptual framework of ‘emotional labour’ associated with Arlie Hochschild-as a means of examining the “nature” of the nurse patient interface, including the dynamics, challenges and intricacies that shape this relationship of care. The portrayal of emotional care offered to patients dealing with suffering and illness by nurses as an entirely natural activity for women is related to the devaluation of emotional labour. The focus of this study is how nurses manage their emotional involvement with patients to provide quality services. The study was conducted in Mthatha in the former Transkei in the Eastern Cape Province with nurses who worked St Mary’s Life Group and the Nelson Mandela Academic Hospital. A qualitative research design and qualitative ethnographic research methodology was chosen as suitable for answering the research question. Data was collected using semi-structured interviews and a focus group, and transcribed verbatim. Data analysis included identifying consistent emotional labour themes in the responses. The study’s main findings revealed that emotional labour strategies of surface acting and deep acting were utilised as a means of meeting organisational rules established by management of the two health care institutions that were investigated. Nurses understood that only desirable traits like include friendliness, smiling and proving a calming environment for patients should be exhibited. It was revealed that nurses often used sentimental work and emotion work in performing their tasks as this made their work easier. Lastly, the research revealed that external factors like overcrowding and shortages in personnel, accompanied by the emotional demands on nurses’ work has adverse effect on nurses work environment. The dissertation has contributed to the limited body of knowledge about emotional labour in the South African context and the lived experiences of nurses deploying their labour to patients.

- Description: Doctor Trudy Thomas is a leader that served; as a medical doctor and as a public servant over five decades during and after the apartheid era in South Africa. The aim of this qualitative study was to identify the leadership characteristics that are evident in Doctor Thomas, the former MEC for Health for the Province of the Eastern Cape; as a leader and to explore how they developed over five decades, given her role within healthcare in South Africa. The first requirement of a servant-leader according to Robert Greenleaf (the contemporary pioneer of servant-leadership) (Greenleaf, 1977), is that the leader is a servant first and starts with a desire to serve. Doctor Thomas started her professional life as a medical missionary doctor, a profession that by its nature is serving and ultimately healing, in the poor rural communities of the Eastern Cape. Her leadership grew out of her initial concern for her patients and their communities and by the opportunities that she was presented with to apply her skills to serve. She was able to identify the deeper needs within these communities and was able to envision practical solutions to these problems, enlisting the assistance of others. Throughout her leadership journey she exhibited humility, and many other trademarks of a servant-leader. She did not see herself as a leader, believing rather that it was a privilege to serve and help people. This study was therefore able to conclude that the leadership that Doctor Thomas has exhibited is that of a servant-leader and that her leadership journey was unintentional and grew out of her desire and ability to serve. This thesis consists of three separate yet interrelated sections. Section One, The Academic Case Study is a holistic, biographical academic case study on an individual. The outcomes of this research are presented as an academic paper, which includes a condensed literature review, results and discussion, as well as recommendations for future research. It also presents recommendations regarding the application of servant-leadership in service industries like Healthcare in South Africa. The presentation of the results is predominantly qualitative with some quantitative aspects. Section Two, The Literature Review presents an extensive review of literature that relates to the phenomena of leadership; servant-leadership; leader and leadership development; servant-leadership development through service and finally servant-leadership in South Africa. Other aspects like Ubuntu and Unintentional leadership are examined. The literature review conducted serves as a broad foundation for understanding servant-leadership but does not purely focus on the issues of this individual study. Section Three, The Research Methodology is an outline of the research aim and objectives, and the research paradigm that has been adopted. The discussion also details the research methodology; the case study method; an inductive approach; an intersubjective position; the individual researched; data collection techniques and analysis; objectivity; issues of quality; ethics; and the limitations of this research.

- Description: This study aimed to gain insight and understanding into adult clients’ personal lived experiences of the post-termination period of long-term psychotherapy. International research which examines the post-termination phase of psychotherapy has found that this particular lived experience can have both positive and negative consequences for clients’ psychosocial wellbeing. Few recent studies focusing on adult clients’ personal experiences of the post-termination phase could be located and none of these studies were conducted in a non-Western context. The study’s aim was to address this gap in the existing literature by using interpretative-phenomenological analysis (IPA) to explore the lived experience of the post-termination period of long-term psychotherapy for two South African adult clients. Data were collected via individual in-depth semi-structured interviews. Analysis of the data yielded the following themes: Therapy remembered as amazing, but hard work, Vivid memories of therapy retained post-termination, Seeing the therapist differently, Keeping the therapist alive, Being different after therapy, “I started losing all my ground I had gained”, and Resuming the external journey. These findings corroborated and expanded upon existing research in the area.

- Description: Background: Breastfeeding is a common practice, but exclusive breastfeeding for the first six months is no longer a cultural norm in the majority of South African communities. Identification of facilitating and constraining factors which affect breastfeeding and exclusive breastfeeding practices is thus important. The promotion of exclusive breastfeeding is essential for improved infant health and development, especially if it takes into consideration the broader cultural and socio-economic aspects influencing these practices. This study follows up on an initial project conducted in Glenmore and Ndwayana, two rural communities in the Eastern Cape, South Africa. The current study aimed at working with community care workers who are associated with two community based organisations, who work within three communities, Glenmore, Ndwayana and Grahamstown. The study objectives were to identify the factors that influence the adoption of exclusive breastfeeding in the communities researched, to conduct workshops with the community workers on exclusive breastfeeding practices, as well as to develop and implement a facilitator’s manual for the promotion of exclusive breastfeeding. Method: Using the community based participatory research approach and the PEN-3 theoretical framework to guide the research process, individual semi-structured interviews were conducted with 14 community care workers to identify the factors that affect breastfeeding and exclusive breastfeeding. Through participatory involvement and a cyclical research process, a facilitator’s manual on breastfeeding was developed, which was used during the workshops in the training of community care workers on breastfeeding and exclusive breastfeeding practices. A pre and post intervention knowledge questionnaire was given to the community care workers to complete before and after the workshops. The facilitator’s manual was modified based on 14 months of consistent interaction with the community care workers, who provided feedback on improving the content as well as on how to enhance the cultural appropriateness of the facilitator’s manual during guided focus group discussions. Readability testing also guided further modification of the facilitator’s manual. Results:The major findings confirmed that exclusive breastfeeding for six months was no longer a common practice in these three communities. Factors affecting breastfeeding and exclusive breastfeeding were classified as perceptions (knowledge attitudes and beliefs), enablers (resources and facilities) and nurturers (people), in accordance with the PEN-3 model thematic categories. The knowledge questionnaire, semi-structured interview results, and data from the workshops showed that the community care workers were not sufficiently equipped with information on breastfeeding and exclusive breastfeeding. The facilitator’s manual development and modification was made possible by inputs from the community care workers and the community based organisation liaisons. A culturally appropriate, community specific facilitator’s manual for the promotion of breastfeeding and exclusive breastfeeding was produced. Conclusion: The factors affecting breastfeeding and exclusive breastfeeding were identified. These factors were useful in facilitating discussions on how to improve breastfeeding and exclusive breastfeeding practices in the communities researched. The facilitator’s manual and the workshops were useful in equipping community care workers with knowledge on breastfeeding and exclusive breastfeeding. The involvement of community based organisations will assist to ensure sustainability of breastfeeding promotion by community care workers by adopting the facilitator’s manual as part of their women and child development programmes.

- Description: This thesis will interrogate the ways in which the most recent novels of Zoë Wicomb and Chimamanda Ngozi Adichie (namely October and Americanah) explore race, gender and transnational issues. Wicomb and Adichie share an interest in representing the lives of people who have been historically marginalised by racial and gender classifications. This thesis will argue that historical and stereotypical ways of looking at people, particularly African people, are still prevalent in the twenty-first century. Wicomb’s interest is in the coloured community and the impact that apartheid ideology has had on it. She shows, as this thesis will argue, that notions of shame and respectability still influence the coloured community, post-1994, in the same ways they did under apartheid. Furthermore, the thesis will show that religion, which was used to justify apartheid, has been instrumental in maintaining racist and sexist norms in the coloured community in post-apartheid South Africa. Adichie’s novel, on the other hand, shows the impact of gender norms in Nigeria on her female characters. Unlike characters in Wicomb’s novel, Adichie’s mostly experience racial bias when they move to Western countries. This thesis will argue that many Western countries, which were the main beneficiaries of colonialism, continue to ‘other’ Africans, in spite of their claims to respect all human beings. Wicomb’s and Adichie’s novels depict characters that are moving between different continents, along with the impact that this has on them. In the twenty-first century, more people are moving between different spaces and, as a result, interacting with different cultures. These migrations, as this thesis will show, give rise to paradoxical circumstances: people are still being judged according to their race and gender, in spite of the freedom that these moves are supposed to lead to. Of central importance to both novels then is the question of home and belonging. Since people are moving between different continents, is it still possible to belong to one place? Is it in fact possible to belong at all? These are some of the questions that will be raised and answered in this thesis. Lastly, the thesis will look at the thematic representations of reading and writing in the novels under consideration. This is most evident in Adichie’s novel where her main character starts blogging as a way to express her dissatisfaction with the racist and sexist environment she encounters in the United States of America. The thesis will explore how Adichie examines blogging as a mode of communication that is unique to the twenty-first century. It will argue that it is perhaps through new media that historically subjugated subjects, such as African people and women, will be able to express themselves. Less hackneyed modes of communication might provide the necessary channels for those who have historically been denied voice to finally find it.

- Description: In the Eastern Cape, a moisture gradient (from west to east) exists along the Escarpment where patches of Southern Mistbelt Forests (SMF) occur. There is a notable profusion of plants in these forests, but the factors that drive plant species composition and abundance in these patches is poorly understood and such knowledge is critical if we are to address or mitigate the problems imposed by global change. Many of our ideas on plant community assembly are based on the premise that species differ in their environmental requirements for successful regeneration, especially when young. The aims of this study were to document the floristic diversity of poorly known patches of Southern Mistbelt Forests in the Eastern Cape and identify the environmental factors that influence plant community composition in these forest patches. Twenty six forest patches across the Eastern Cape were sampled. In each forest 400m2 circular plots were constructed. The diameter at breast height and stem counts for the tree species was taken and the % cover of the herbaceous species was recorded. General collections were also made to supplement the plot data in order to obtain a comprehensive flora for each forest patch. All sampling was done during the summer season of 2013 and 2014. Using plot data, Hierarchal Cluster Analysis and Multidimensional Scaling Analysis were done to compare similarities between patches. Plots from the same forest patch clustered which indicated that the species composition in each forest patch was unique. However, this pattern went down when only tree species were considered. Plant diversity also varied between patches; with those located in the east being generally more diverse than those in the west are. Clustering patterns in fragmented communities and differences in species diversity indicate evidence of species “nestedness”. Analysis of nestedness indicated that these forest patches were significantly nested. To identify which environmental variables might be correlated with both species diversity and nestedness, twelve environmental variables was selected for analysis using Canonical Correspondence Analysis and Principal Component Analysis. Results show that Mean Annual Precipitation, Mean Annual Potential Evapotranspiration, and percentage of Organic Matter of the soil were most strongly correlated with the patterns of diversity observed in these forest patches. Regression analysis indicated that Mean Annual Precipitation accounted for most of the variation in species diversity, especially for the herbaceous species. The herbaceous species thus show a greater sensitivity to “climate filtering” as a consequence of rainfall gradients. With the implementation of suitable monitoring programs, changes in abundance or even local extinction of these species can act as an early warning indicator of the possible long-term effects of climate change on forest communities.

- Description: Black Locust (Robinia pseudoacacia L.) is an invasive deciduous, strongly suckering, broad- leaved tree that has the potential to be widely distributed across a large portion of South Africa. Robinia pseudoacacia has invaded all nine of South African provinces, with large infestations found in the Eastern Cape, Kwa Zulu-Natal, Free State and Gauteng provinces. The invasive tree has the potential to spread into livestock grazing lands in South Africa. Because R. pseudoacacia has the ability to spread and thrive in a variety of habitats and resists control, the distribution of the invasive tree into grazing land poses a problem for landowners. The potential economic impacts of R. pseudoacacia on agricultural production stem from the trees ability to reduce the carrying capacity of livestock. This study estimated the potential economic implications of R. pseudoacacia on agricultural production in South Africa, specifically looking at the livestock sector. The prevalence of R. pseudoacacia potential distribution was calculated by using a maximum-entropy predictive habitat model, MAXENT. The distribution of livestock, based on grazing capacity (ha/LSU), in South Africa was then determined. The potential direct economic impacts were estimated by assessing the impact of the potential distribution of R. pseudoacacia on the carrying capacity of livestock. The results showed that an infestation of R. pseudoacacia has the potential to reduce the gross margin in the livestock sector by between approximately R130 million and R961 million, dependent on the probability of invasion. Therefore, the potential invasion of R. pseudoacacia can have detrimental effects on the livestock sector in South Africa. The potential high levels of foregone income and business activity found in this study reaffirm the need to devote resources to develop a viable, economical and effective control method, such as biological control.

- Description: This study focuses on literature. The dissertation seeks to explore how Magqashela’s works Isangxa siyawhuza (2006), Amathaf’entandabuzo (2006) and Umlindi (2015) represent her characters to reveal gender based violence and stereotypes. As we, South Africans enfranchised and given the Act 108, a South African Constitution with Bill of rights, but it seems as if women and children do not enjoy these privileges because of high rate of violence against them. Through observation it is clear that theoretically every South African is free but practically some humans particularly women and young girls and discrimination. The researcher decided to choose female writer assuming that she is addressing women challenges as male writers are less interested to excavate women’s issues in their literary works. The reseacher also wanted to find out whether our female writer is disseminating women’s predicaments. By means of textual analysis the study investigates how gender based violence violates survivors and victims’ rights in chapter 3, and chapter 4 explores how unfaithful partners cause violence. It also explores the intervention of traditional justice and formal justice system in violent behavior caused by anger, jealousy and acquaintance of violent environment. Chapter 5 projects a stereotypical character in three selected literary texts. The whole thesis brings the prominent picture of how Gender Based Violence bodily harm the survivors and victims psychologically, physically and economically. It reveals rural women and young girls as the most vulnerable people and men as the worst perpetrators of Gender Based Violence in these literary texts. The thesis explains that the perpetrators are known by the survivors and victims hence there is a culture of silence. They are afraid of multiple abuses. The thesis relates character depiction of violence and stereotypes with current societal incidents quoting from newspapers, articles, journals and SABC online news as to disclose the accuracy of the author’s projection. Character analysis reveals that women are still discriminated and oppressed by their counterparts. The discussions succinctly elucidate that the underestimation of women and children are rooted by cultural traditional norms and values as well as Christian religion .These societal factors are promoting patriarchal perception which says men are dominant and women are submissive. It says men are obliged to take control over women. African feminist theory; Feminism, Womanism and Stiwanism and Motherism are employed as a theoretical framework. These theories are against gender inequality, they are against African women and children maltreatment .The changes of the current society including women’s independency propels insecurity, unemployed, illiterate and underprivileged men to use violence as the way of taking back control over their intimate partners and the whole family. Relevant quotations from selected texts are employed to project character portrayal of gender based violence and stereotypes.

- Description: Introduction: Studies reveal differential cognitive effects of alcohol use, with moderate to heavy alcohol having some beneficial effects in older adults, whereas in young adulthood, heavier alcohol use produces deficits. The aim of the research was to investigate the relationship between patterns of alcohol use and the cognitive and symptomatic functioning of university students over one year, and to discern which demographic, clinical and alcohol factors might moderate cognitive outcomes. Method: The sample included undergraduate Psychology students from a South African University, aged 18 to 23 years (n = 86). The sample was divided into two alcohol use groups based on four categories from the Alcohol Use Disorders Identification Test (AUDIT) (Babor et al., 2001), including a lighter drinking group (Safe/Hazardous, n = 74) and a heavier drinking group (Harmful/Dependent, n = 12). The two drinking groups were statistically equivalent for distribution of age, gender, English first language, race groups, history of neurological or psychiatric vulnerability, a measure of initial intelligence/cognitive reserve (Peabody Picture Vocabulary Test: PPVT-4) (Dunn & Dunn, 2007) and for a measure of test-taking validity (Immediate Postconcussion Assessment and Cognitive Test: ImPACT Impulse Control) (p = < 0.05 in all instances). Participants were tested on the computerized ImPACT battery (ImPACT, 2007) at three intervals over an academic year (May, August, October 2012). Repeated measures ANOVAs were used to investigate cognitive and symptomatic differences between the two alcohol use groups, in association with moderating factors. Results: The heavier drinking group revealed: (i) poorer performance on ImPACT Visual Motor Speed, Reaction Time and Cognitive Efficiency Index scores, including less ability to benefit from practice over time; (ii) symptom reports of severe Numbness/Tingling, Balance problems and Dizziness. Deleterious cognitive outcome was exacerbated by longer lifetime duration of alcohol use, passing out monthly, beer or wine drinking, smoking or substance use. Conclusion: Deleterious cognitive and symptomatic effects of heavy alcohol use are in evidence for undergraduate university students implicating current and/or cumulative alcohol induced brain impairment. The results of the study are of concern for optimal academic performance of students at an early stage of university level study, who engage in heavier (Harmful/Dependent) drinking patterns, with negative implications for future career attainment.
