- Description: The objective of this paper is to investigate the Rotterdam Rules, and to ascertain whether South Africa should accede to or ratify them. In order to accomplish this, South Africa's current maritime transport regime will be examined, and existing "problem areas" will be identified. This will be followed by a comparative analysis between the Rotterdam Rules and the Hague-Visby Rules, which South Africa applies as part of national law to regulate the carriage of goods by sea. As a new maritime Convention, the Rotterdam Rules have attracted widespread criticism and support, and whether such is justified will also be considered. Finally potential considerations South Africa should take into account in electing whether or not to accede or ratify the Rules have been assessed from a political, economic, social, technological, legal and environmental standpoint as at 31 December 2011

- Description: South African hospitals, as a result of numerous factors, have the problem of an increasing workload for nursing staff, which in turn may affect patient treatment quality. This project aimed at addressing patient treatment quality specifically from the perspective of worker capabilities by investigating the strain level and predicted human error probability associated with specific patient-centered tasks in the South African health care sector. This was achieved through two independent yet interlinked studies which focused on seven patient-centred tasks. The tasks analysed were the tasks of setting up and changing intravenous medication, administering injection and pill medication, measuring blood glucose, temperature and heart rate and blood pressure. In the first study, work environment and task characteristics, task structure and execution were analysed. In addition to the task execution, the resulting strain levels, in the form of heart rate measures and subjective ratings of workload, were studied. The second study determined the error protocols and predictive error probability within the healthcare environment for the seven pre-defined tasks. The results for the first study established that different organizational and environment factors could affect task complexity and workload. The individual task components and information processing requirements for each task was also established. For the strain analysis, significant results for the tasks were determined for heart rate frequency and the heart rate variability measures, but some of these were contradictory. For the second study, specific error protocols and error reporting data were determined for the hospital where this research was conducted. Additionally the predictive error probability for the pre-defined tasks was determined. This combined approach and collective results indicate that strain and predictive error probability as a result of task workload can be determined in the field as well as being able to identify which factors have an effect on task strain and error probability. The value of this research lies in the foundation that the gathered information provides and the numerous potential applications of this data. These applications include providing recommendations aimed at improving nursing work environment with regards to workload, improving patient treatment as a result of a reduction in errors and the potential foundation these results provide for future research

- Description: Under the guidance of the new coastal management policies within South Africa this thesis advocates a more integrated, co-operative approach to local coastal management. The project aimed to acquire baseline information on the local nearshore fishery and resource state and to propose a set of indicators that could be incorporated into the new management strategy. To gather the required information the project was split into two parts: 1) An assessment of the local linefisheries and 2) A comparative study of the reef fish community structure between exploited and unexploited reefs. The local linefisheries were assessed through the use of launch records, commercial catch records, access point and boat based surveys. A questionnaire was used to gather data on catch and effort, fisher demographics, fisher attitudes towards and knowledge of the current management regulations, assess the efficacy of the fisheries inspectorate and highlight spatial areas of fishing pressure. A total of 252 interviews and catch inspections were conducted. Total effort for the ski-boat fishery estimated from the access point survey was 890 boat days.year⁻¹ or 3560 fisher days. year⁻¹ compared to 736 boat days.year⁻¹ or 2944 fisher days. year⁻¹ recorded in the launch records. Effort was seasonal with greater pressure occurring over the summer holiday period. Analysis of the catch showed that Merluccius capensis, Argyrozona argyrozona, Argyrosomus inodorus, Chrysoblephus laticeps and Atractoscion aequidens were the most frequently caught species. The overall CPUE was 3.00±5.54kg.fisher⁻¹.day⁻¹ or 4.71±4.117 fish.fisher⁻¹.day⁻¹. Estimated targeted CPUE was 0.91±0.67kg.fisher⁻¹.day⁻¹ or 0.97±0.77 fish.fisher⁻¹.day⁻¹ for C. laticeps, 8.47±8.57kg.fisher⁻¹.day⁻¹ or 1.24±1.16 fish.fisher⁻¹.day⁻¹ for A. aequidens and 2.05±3.78kg.fisher⁻¹.day⁻¹ or 1.10±1.80 fish.fisher⁻¹.day⁻¹ for A. inodorus. Issues identified included poor fisher knowledge regarding linefish regulations, the low occurrence of fishery inspections and a limited degree of noncompliance. Although most fishers supported the current linefish management regulations, when tested on the size limits, bag limits and closed seasons of their target species a high proportion of fishers did not know the regulations (recreational 64%, charter 53%, commercial 42%). Furthermore only 27% of fishers had had their catch inspected whilst fishing in Plettenberg Bay and the majority of these had only been inspected once. Just over half the interviewees (60%) indicated that fishing had deteriorated within Plettenberg Bay with fewer and smaller fish being caught. The most common causes cited for this decline were commercial and recreational overfishing respectively. Underwater point counts and experimental angling were used to rapidly assess the state of the reef fish resource in Plettenberg Bay through a comparative study of the community structure between two exploited sites in Plettenberg Bay and two protected sites within the Tsitsikamma National Park. Generalized linear modeling showed that relative density of certain species was significantly different between the protected reefs inside the TNP and those exploited reefs within Plettenberg Bay. Both P. rupestris and C. laticeps had greater densities within the protected area whilst Chisquared tests showed that the size frequency distributions were significantly different with larger size-classes and the maximum size of fish greater within the reserve. These trends were noted with both the underwater visual surveys and the experimental angling. Multi-dimensional scaling and cluster analysis showed that there was an overall difference in the community structure between the study sites. It is hypothesised that through removal of key reef species and larger individuals that fishing has directly and indirectly affected the overall community structure. Within a simple framework based on ecological, institutional and social sustainability domains along with the results of the study area, a set of indicators is proposed and the sustainability of the local fishery scored within a rapid assessment matrix. The socio-economic domain scored the highest (83%) whilst the institutional domain scored the lowest (8.3%) and the ecological domain scored 25%, giving a total sustainability score of 38.8%. The results of this matrix show that at present the local fishery is non-sustainable and in need of greater management. By synthesizing papers dealing with and based on the concepts involved in Integrated Coastal Management, a structured approach is proposed to developing and implementing more holistic local coastal governance. It is envisaged that the framework to implement such an approach should be through the development of a local Coastal Management Plan and a subsidiary Bay Management Plan. Although stakeholder participation and representation is an essential component in the development of these plans, it is recommended that the local municipality should be the lead agent and incorporate the plans into the local Integrated Development and Spatial Plans thereby gaining long term local government support.

- Description: A cognitive behavioural treatment program for chronic lower back pain was designed, implemented and evaluated. The outpatient treatment program included education sessions, goal setting, graded activity training, physical exercise, relaxation training, cognitive techniques, social skills training, and medication reduction. Three participants volunteered to participate in the eightweek treatment program. Of the three participants, only one completed the program successfully. The results were used to critically discuss and evaluate the literature. The successful participant showed significant improvement in activity levels, decrease in subjective levels of pain, as well as decreased levels of anxiety and depression. It was shown that correcting cognitive distortions (e.g. selective abstraction, catastrophising, misattribution) and challenging early maladaptive schemas of abandonment, emotional deprivation and emotional inhibition (Young, 1990) assisted in enhancing coping mechanisms and the belief that the pain episodes would be short-lived and could be controlled. There was considerable improvement for the second participant, although he chose to withdraw from the program prior to its completion. The components of the psycho-education, relaxation and stress management and exercise program were beneficial for him. The third participant failed to accept the treatment formulation, and did not engage collaboratively in the treatment program. The case is presented as a point for examining therapeutic ailures.
