- Description: Linda is an approach to parallelism which relies on a virtual associative shared memory called tuple space. Tuple space is accessed through a small set of primitive operations and is conceptually easy to understand and manipulate. The physical implementation of a Linda tuple space may of course be completely different from the conceptual model. Rhodes has implemented versions of Linda on a ring of RS-232 joined PC's and on a cluster of T800 transputers with a single copy of tuple space on one transputer. Current research targets the implementation of a distributed Linda server on a network of heterogeneous processors. This work describes the design and implementation of a distributed Linda server. Emphasis is placed on aspects of the design which enhance portability and efficiency.

- Description: This thesis investigates event-based behavioural model debugging in Linda. A study is presented of the Linda parallel programming paradigm, its amenability to debugging, and a model for debugging Linda programs using Milner's CCS. In support of the construction of expected behaviour models, a Linda program specification language is proposed. A behaviour recognition engine that is based on such specifications is also discussed. It is shown that Linda's distinctive characteristics make it amenable to debugging without the usual problems associated with paraUel debuggers. Furthermore, it is shown that a behavioural model debugger, based on the proposed specification language, effectively exploits the debugging opportunity. The ideas developed in the thesis are demonstrated in an experimental Modula-2 Linda system.

- Description: With the evolution of parallel and distributed systems, users from diverse disciplines have looked to these systems as a solution to their ever increasing needs for computer processing resources. Because parallel processing systems currently require a high level of expertise to program, many researchers are investing effort into developing programming approaches which hide some of the difficulties of parallel programming from users. Linda, is one such parallel paradigm, which is intuitive to use, and which provides a high level decoupling between distributable components of parallel programs. In Linda, efficiency becomes a concern of the implementation rather than of the programmer. There is a substantial overhead in implementing Linda, an inherently shared memory model on a distributed system. This thesis describes the compile-time analysis of tuple space interactions which reduce the run-time matching costs, and permits the distributon of the tuple space data. A language independent module which partitions the tuple space data and suggests appropriate storage schemes for the partitions so as to optimise Linda operations is presented. The thesis also discusses hiding the network topology from the user by automatically allocating Linda processes and tuple space partitons to nodes in the network of transputers. This is done by introducing a fast placement algorithm developed for Linda. , KMBT_223

- Description: Computers connected to a local area network are often only fully utilized for short periods of time. In fact, most workstations are not used at all for a significant portion of the day. The combined "idle time" of the workstations on a network constitutes a significant computing resource, which is generally wasted. If harnessed properly, such a resource could constitute a cheap alternative to expensive high-performance computers. Adaptive parallelism refers to the parallel execution of a computation on a dynamically changing set of processors. This thesis investigates the viability of this approach as a vehicle to harness the "idle cycles" available on a heterogeneous cluster of networked computers. A system, called Remora, which implements adaptive parallelism via the Linda programming paradigm, is presented. Experiments, performed using Remora, show that adaptive parallelism provides an efficient vehicle for using idle processor cycles, without having an adverse effect on the tasks which constitute the normal workload of the computers being used.

- Description: The death of a parent is one of the most serious stressors that can occur in a child’s life. The aim of this study was to describe an 11-year-old child’s journey through traumatic grief after the violent death of her mother. The conceptual framework utilised was Trauma-Focused Cognitive Behavioural Therapy (TF-CBT). The case study approach was applied as it provided a suitable research design in which to give an account of the subject in a therapeutic situation. A purposive sampling technique was utilised to select the research subject in the study. The following three principles of data collection were adhered to: a) using multiple sources of information, b) creating a case study database, and c) maintaining a chain of evidence. Irving Alexander’s content-analysis technique in conjunction with Guba’s model of trustworthiness was employed for data analysis. The finding that emerged from the study was the resilience shown by Linda in relation to her adaptive functioning following the trauma of witnessing the violent death of her mother. Conclusions and recommendations were made following the findings based on the information obtained during the therapy sessions.

- Description: This thesis investigates nondeterminism in functional programming languages. To establish a precise understanding of nondeterministic language properties, Sondergaard and Sestoft's analysis and definitions of functional language properties are adopted as are the characterizations of weak and strong nondeterminism. This groundwork is followed by a denotational semantic description of a nondeterministic language (suggested by Sondergaard and Sestoft). In this manner, a precise characterization of the effects of strong nondeterminism is developed. Methods used to hide nondeterminism to in order to overcome or sidestep the problem of strong nondeterminism in pure functional languages are defined. These different techniques ensure that functional languages remain pure but also include some of the advantages of nondeterminism. Lastly, this discussion of nondeterminism is applied to the area of functional parallel language implementation to indicate that the related problem and the possible solutions are not purely academic. This application gives rise to an interesting discussion on optimization of list parallelism. This technique relies on the ability to decide when a bag may be used instead of a list.

- Description: This article explores how lesbian identity construction is facilitated and constrained by the raced, classed, gendered, familial, and geographical spaces that women occupy. We present a narrative-discursive analysis of eight lesbians’ stories of sexuality, told within a historically white university in South Africa. Three interpretative repertoires that emerged in the narratives are discussed. The ‘disallowance of lesbian identity in particular racialised and class-based spaces’ repertoire, deployed by black lesbians only, was used to account for their de-emphasis of a lesbian identity through the invocation of a threat of danger and stereotyping. The ‘disjuncture of the (heterosexual) family and lesbian identity’ repertoire emphasised how the expectation of support and care within a family does not necessarily extend to acceptance of a lesbian identity.

An application for real time raytracing through the South African ionosphere was identified, and for this application real time evaluation of the electron density profile is essential. Raw real time virtual height data are provided by a Lowell Digisonde (DPS), which employs the automatic scaling software, ARTIST whose output includes the virtual-to-real height data conversion. Experience has shown that there are times when the raytracing performance is degraded because of difficulties surrounding the real time characterisation of the F1 region by ARTIST. The purpose of this investigation is to establish the extent of the problem, the times and conditions under which it occurs, with a view to formulating remedial alternative strategies, such as predictive modelling.

- Description: Over a period of nine months in 1999, a longitudinal teaching intervention was undertaken with Grade 3 learners in the Fort Beaufort district, Eastern Cape. Working in the interpretive paradigm, the intervention focussed on: - the development of the common fraction concept, - the relevance of the hierarchy of Murray and Olivier’s Four Levels of Development in common fractions and - whether learners’ informal knowledge could be utilised in developing this concept. Using the Problem-centred approach to teaching mathematics, problems set in reallife contexts were used as vehicles for learning. Learners were required to discuss, reflect and make sense of the mathematics they were doing. Participant observation, completed worksheets and unstructured interviews with learners, formed the primary method of data collection. Learners’ work was analysed and classified according to the method used and manner in which the solution was notated. Results showed that learners were able to achieve a significant degree of success in developing a stable common fraction concept. Learners were afforded opportunities to construct their own ideas and to develop a deeper understanding of the concept. Many methods used were based on their informal knowledge of sharing. Learners made sense of realistic problems using drawings, and invented their own procedures. Apart from Level One, Phase Three, all Murray and Olivier’s Levels of Development could be identified during the research. This study will provide educators with valuable information on how learners solve mathematical problems involving fractions and how informal knowledge can be used as a foundation on which to build.

- Description: There has been insufficient academic research on the music of the Eastern Cape in general and Port Elizabeth and New Brighton in particular. This study, as part of the International Library of African Music (ILAM)lRed Location Museum Music History Project (ILAMIRLMHP) - an oral history intervention to save the music history of New Brighton from extinction through research and documentation of the memories of veteran musicians - is focused on jazz vocalists. The primary objective of my study is to investigate, critically analyze, interpret and document the career experiences of six New Brighton jazz vocalists in the context of performing in the Port Elizabeth music industry during the apartheid and the post-apartheid eras. The secondary objectives are to stimulate research interests in music students and ethnomusicologists to pursue research on the music of Port Elizabeth and the Eastern Cape and to inspire and motivate the vocalists to continue making music with renewed zeal. A qualitative research paradigm informed the field research necessary for this study. The fieldwork paved the way for an eclectic framework of analysis grounded in Pierre Bourdieu's notions of habitus, field and capital, examining the impact of the context on the vocalists' habitus which influenced how they viewed and interpreted their past and current experiences in the performance field. Data obtained through extensive interviewing of New Brighton's contemporary female vocalists and their male counterparts revealed that they have no opportunity to make commercial recordings. The musicians have to migrate to Johannesburg to have successful music careers, although personality politics, greed and lack of professionalism also work against the musicians' success. The data shows that New Brighton musicians, both male and female, do not have enough performance opportunities and there are fewer chances to tour now than there were from the 1960s through the 1980s. As in the apartheid era, female vocalists are still discriminated against in terms of pay, and men discriminate in how they pay other male musicians. Analysis of the vocalists' jazz compositions revealed that their song lyrics depict a bona fide urban African culture and reflect the emotional needs of the society in which they live.

- Description: The present study presents three individual cases; all three clients had endured a traumatic event, namely rape, and all three met the criteria for PTSD. Despite the fact that each of the clients was initially assessed as being a suitable candidate for psychological treatment, none of the cases proceeded to the therapy phase of treatment. A number of obstacles, both personal and contextual, were encountered during treatment implementation, preventing or limiting a successful outcome of psychological treatment in each case. An examination of these cases highlights a few of the many obstacles frequently faced when delivering psychological treatment to the South African context. In so doing, this research provides an opportunity to consider the possible reasons for the limited documentation of treatment efficacy within the South African context, as well as to enhance our understanding of and sensitivity towards the cultural and contextual factors playing a role in psychological treatment.

- Description: [From the Introduction] 2011 saw the consolidation of a number of changes to Library services implemented in 2010 as a result of the 2009 Review of the Library Services Division. These include: 1) Collection development operating as a collaborative effort between Library staff and the academic community. The Collection Development Policy also underwent a major revision and was approved by Senate in October as the “Collection Development and Management Policy and Guidelines”. 2) The Faculty Liaison Service – the librarians in these teams are now proactively liaising with academics, for example, playing a crucial role in collection development for the departments, ensuring that they spend their information resources grants, creating awareness of appropriate online information resources and offering information literacy workshops.
