- Description: False codling moth (FCM), Thaumatotibia leucotreta (Meyrick) (Lepidoptera: Tortricidae) is indigenous to southern Africa and is an important pest of citrus in this region. As a result of its endemism to sub-Saharan Africa, several countries to which South Africa exports citrus, regulate it as a phytosanitary pest. Consequently, it is necessary to ship fruit to these markets under cold-disinfestation protocols. This has been possible, as until recently, all of these markets could be considered relatively small niche markets. The South African citrus industry exports approximately 130 million cartons of fruit (15 kg equivalent) annually. During the 2017 season, a total of 48 million cartons were exported to the European Union (EU), which is the equivalent of 41% of South Africa’s total export volume, thus making the EU South Africa’s most important export market. In 2013 the European and Mediterranean Plant Protection Organisation (EPPO) conducted a pest risk analysis (PRA) on FCM, leading to the EU declaring it an officially regulated pest for this region, effective of 1 January 2018. Citrus is regarded as a preferred non-native host of FCM and South African citrus was identified as a primary focus due to large volumes being exported to Europe. Shipping under cold disinfestation is not possible with such large volumes of fruit. Additionally, several cultivars would suffer high levels of chilling injury under such conditions. In this study, an Integrated Management System was tested with pre- and postharvest controls to test the hypothesis that pre-harvest interventions resulted in lower post-harvest infection. Thirty orchards ranging from soft citrus cultivars such as Nule and Nova Mandarins, to Navel orange cultivars such as Newhall, Palmer and Late Navel and ending with Valencia cultivars such as Midknight and Delta, were identified for this study. This system relies on pre-harvest inspections such as FCM trap counts and fruit infestation on data trees in every orchard, with associated thresholds for action or continued compliance. Inspections were conducted on a weekly basis. There was a significant relationship between the moth catches and FCM infestation for the full monitoring period, using a two-week lag period for infestation. Inspections of harvested fruit were conducted at the packhouse to determine FCM infestation. This included inspection of the fruit on delivery to the packhouse, on the packing line, and a final fruit sample taken from the packed product and inspected for FCM. The highest levels of infestation were recorded on the Navel cultivars, thus confirming that Navels cultivars are a preferred host for FCM. Significant positive relationships were recorded between FCM infestation during the last 4 weeks before harvest and the level of infestation in the fruit delivered to the packhouse and between the fruit delivered to the packhouse and in the fruit packed in a carton for export. There was a substantial reduction in infestation between the fruit delivered to the packhouse and the fruit packed in a carton for export, with certain orchards recording as much as a 93% reduction in the fruit packed in a carton, which indicated that the packhouse could effectively identify and remove FCM infested fruit. The outcome of the study is that a holistic management approach minimizes the risk of FCM in citrus fruit destined for export and therefore mitigate the risk associated with FCM.

- Description: Learners in Namibian primary schools are seemingly not brave enough to stand and raise their voice on issues that concern them. This is what Shekupakela-Nelulu (2008) wrote after a study she conducted on the Learners’ Representative Council (LRC) of a school in Namibia. She refers to a time when “the involvement of students in school affairs was seen by the regime as a political act and attempts by student leaders to involve themselves in educational issues were often quashed” (ibid., p. i). This situation will be all too familiar to South African readers, where a public holiday, Youth Day, was declared to mark the apartheid regime’s brutal treatment of learner protestors on June 16, 1976. While Namibia has not experienced events of such magnitude, the notion of learner voice is equally problematic and worthy of investigation. The absence of leadership development opportunities for learners has led to this research study which seeks to answer the central research question: How can learner leadership be developed in a LRC? I used an interpretive paradigm, adopting a qualitative approach in the study. Concurrently, the study was framed and guided by the second generation of Cultural Historical Activity Theory (CHAT) as an analytical tool to achieve my research goal. The following questions guided the study in two phases. Phase one: What were the perceived causes for the nonsustainability of the learner leadership (LL) club at the school? Phase two: How is the notion of learner leadership understood in the school? How is leadership developed on the LRC? What enables and constrains leadership development of learners on the LRC? The research participants were thirty LRC members from grades 6 and 7 and15 teachers who teach the LRC members. The principal and three HOD’s were also research participants being part of the Senior Management team. One of the HOD’s also fulfils the role of the guardian teacher to the LRC. A school board chairperson also participated in the Change Laboratory Workshop. Data was generated through multiple data sources such as questionnaires, individual interviews, a focus group interview and observation. The findings from phase one of the study revealed that the learner leadership club’s intervention was a success during the 2014 academic year, but the absence of the learner leadership club as an extra-mural activity affected the sustainability of the club into the next academic year 2015. Findings from phase two revealed that leadership opportunities did exist at the school for learner leadership development. However, a few challenges emerged relating to traditional views of leadership and constraining factors that could affect learner leadership development at the school. Thus, Change Laboratory workshops were held to find solutions to the challenges, in order to promote and enhance learner leadership development, hopefully for the future of the Namibian child.

- Description: The negative effects of localised muscle fatigue on accidents, injuries and poor work performance are well known, as is the realisation that modifying task characteristics can minimise fatigue development. A large amount of literature has investigated the effects of task-dependent factors on localised muscle fatigue, most studies have focussed on prolonged or intermittent static (isometric) exertions. Few studies have investigated muscle fatigue development during more complex tasks, namely those which resemble common work activities and which tend to be intermittent and dynamic in nature. More specifically, the interactions between the main intermittent parameters - duty cycle, force level, and cycle time - during dynamic exertions are poorly understood. The purpose of this study was to investigate the effects of cycle time and combinations of duty cycles and force levels on the development of muscle fatigue during submaximal dynamic exertions while the overall mean muscle load was kept constant. A two-factorial repeated-measures experiment was developed for this study. Nine experimental conditions, each lasting 16 minutes, aimed at inducing muscle fatigue in the middle deltoid muscle via intermittent dynamic shoulder abduction and adduction motions at three cycle times (30, 60, and 120 seconds) and three combinations of duty cycles and force levels. The percentage of muscle activation during one cycle (i.e. the duty cycle) varied depending on the exertion intensity (force level) so that the overall mean muscle load remained consistent throughout all experimental conditions, namely at 20% of maximum force exertion. As a result, the three duty cycle/force level combinations were: 0.8/25% of maximum voluntary force (MVF), 0.5/40%MVF, and 0.4/50%MVF. Muscle fatigue development was inferred by changes in peak torque, total work, average power, local Ratings of Perceived Exertion (RPE), and surface electromyographical (EMG) activity (time domain and frequency domain).Two-factorial analyses of variance with Tukey post-hoc tests were used to identify significant condition effects at p<0.05. All dependent measures showed that muscle fatigue was induced by the 16-minute fatigue protocol. Peak torque, total work, average power, and EMG percentage of maximum showed that cycle time and the duty cycle/force level combination had no effect on the development of muscle fatigue, whereas the measures evaluated during the 16-minute fatigue protocol did. The cycle time of 120 seconds induced the greatest change in six of the eight variables, while the duty cycle/force level combination (0.8/25%) also resulted in the greatest effect in six of the measures. Fatigue was also found to be dependent on the interaction of cycle time and duty cycle/force level combination. The conclusion draws from this study is that shorter cycles and activities with short activation periods, and proportionally longer rest breaks result in the lowest fatigue developments.

- Description: The Port Elizabeth (PE) hospital complex is one of the public hospital groups in South Africa facing a critical shortage of medical practitioners, with reference to doctors in particular. In the quest of finding how to retain doctors in the hospital complex, the aims of this research were to survey doctors’ career intentions; to investigate factors that could be contributing to these career intentions so as to uncover some of the reasons why doctors are leaving the public sector; and to identify effective ways in which the government and hospitals might improve retention by pointing out areas that need improvement. The factors that influence doctors’ career intention included income, work conditions, risk of contracting infection, risk of injury at work, hours of work, work load, work related stress, paid leave days, resources, personal growth and development opportunities, ongoing training opportunities, advancement and promotion opportunities, relation with co-workers, relations with supervisor/superiors, and sense of meaning. Findings revealed that even though the tendency to leave’ group (43%) was smaller than the ‘tendency to stay’ (57%), the majority (85%) of those who intended to leave were younger doctors. Despite some significant differences in responses between the two groups, results revealed that both groups were dissatisfied with almost all conditions of work apart from relationships with supervisors and co-workers. To a large extent, both groups revealed that work conditions are better in the private hospitals than in their current hospitals. viii The fact that some doctors could stay in the public hospital sector despite intense dissatisfaction with conditions of work, and despite the perception that that there are better options in the private hospitals could be attributed to the fact that most of these doctors are older and are at their retirement stage . Adding to this is that most of these doctors, who indicated willingness to say, scored high in sense of meaning as a factor influencing their career intention. This research was based on the assumption that there was no retention strategy put in place to solve the problems facing PE hospital complex. However, during this research a strategy was being developed and implemented by the Eastern Cape Department of Health. Therefore, evaluation and recommendations of the strategy are provided in the conclusions of the study. These recommendations relate not only to the implementation of the strategy, but improving it to accommodate all problems currently facing the doctors and finding ways and means of making the strategy sustainable; creating private-public partnerships; focusing on creating a sense of meaning amongst the doctors (especially the younger ones) and focusing on retaining the risk group which was the younger doctors.

- Description: This exploratory study investigated the expansion of an established systematized group dreamwork method (Shuttleworth-Jordan, 1995) to incorporate artwork. The rationale for the addition of artwork was situated firstly, in a poetic Jungian understanding of the image as a holistic "place" of gnosis or transformative healing and, secondly, in an argument that in order to carry the gnostic potential of the image into the lived world, a dreamwork method should involve all four styles of consciousness (thinking, intuition, sensation and feeling). It was considered that the verbal interpretive Shuttleworth-Jordan method would be enhanced by the incorporation of a visual artwork process in order more fully to open the potential of the method for incorporating the nonverbal intuitive, sensation and feeling styles of consciousness. In order to compare the established method (dreamwork Without Art) and the proposed method (dreamwork With Art), two dreamwork workshops were conducted in which all participants experienced all four conditions of the study: Dream Presenter Without Art, Dream Presenter With Art, Group Member Without Art, Group Member With Art. Two levels of assessment were utilized: a quantitative analysis (involving rating scales completed after each dreamwork session), supported by a qualitative analysis (involving written questionnaires completed at the end of the workshops and follow-up interviews conducted a week after completion of the workshops). The results suggested that the incorporation of artwork in the Shuttleworth-Jordan (1995) group dreamwork method enhanced the established method in that a consistent trend of increased involvement in the dreamwork process and increased dreamwork effectiveness was reflected, while no deleterious effects were noted which might detract from the effectiveness of the existing model which had been established in previous research studies. Finally, a refined step-by-step group dreamwork method incorporating artwork was proposed, which included qualitative feedback from the present study.

- Description: Issues of group identity and prejudice have played a large role in the history of South Africa. To examine differences between White English- and Afrikaans-speaking adolescents within the context of the "new" South Africa, data was collected from 553 high school students using a questionnaire which assessed aspects of these groups' perceptions of themselves (their identities), attitudes toward other racial groups (their prejudices), and beliefs about their rapidly changing socio-political environment. A discriminant function analysis conducted with these variables correctly identified group membership at a rate much higher than chance (p < .00001). Post hoc univariate analyses indicated that compared with Afrikaans-speakers, English-speakers demonstrated significantly less identification with their own culture, less racial prejudice but also less willingness to make retribution to those who were oppressed by Apartheid, and less concern/confusion over the recent changes which have taken place in the country. Descriptive and correlational analyses also provided additional, valuable information regarding the variables assessed in the study. Overall, the results seemed to indicate that the adolescent subjects of this study find themselves in a state of transition.
