Thesis (MA)--University of Stellenbosch, 2003. / ENGLISH ABSTRACT: Counselling has been recognised as an important component ofHIV and AIDS care, and an essential part ofHIV testing. Counsellors are involved in a dynamic interrelationship with their clients as well as with the organisations in which they work. From a psychoanalytic framework, unconscious anxieties can playa role in the work of the counsellor. Transference and countertransference are processes, which are involved in the counselling situation. While these processes can be a source for understanding the client, they may also become problematic for the counsellor when they overwhelm the counsellor. This study explores the experiences of HIVIAIDS counsellors attached to Lifeline, Khayelitsha in Cape Town. Twenty-nine counsellors were interviewed using individual interviews and focus group discussions. Results explore the counselling training and activity; the difficulties of counselling; what helps the counsellor to cope; and the general impact that counselling has had on the counsellors' lives. The findings reveal the difficult and often distressing aspect of counselling persons with HIVand AIDS. A number of issues facing the client, as well as cultural and workplace issues may cause difficulties for the counsellor. In addition, the nature of the disease, and the issues it creates for the patient, can arouse a number of anxieties in the counsellor related to their own past. The results reveal some possible limitations to an individual client-centred approach. The study concludes that psychodynamic issues should form part of the counsellor's training, and be explored during regular counsellor supervision. / AFRIKAANSE OPSOMMING: Berading is erken as 'n belangrike komponent in HIV en VIGS sorg, en 'n essensiele deel van HIV toetsing. Beraders is betrokke in 'n dinamiese verhouding met hul kliënte so wel as die organisasies vir wie hulle werk. Vanaf 'n psigoanalitiese raamwerk kan angs in die onderbewussyn, 'n rol speel in die werk van beraders. Oordrag en teenoordrag is prosesse wat betrokke is by die beradingsituasie. Alhoewel die proses 'n bron is wat tot beter verstandhouding met die kliënt kan lei, mag dit ook die berader oorweldig. Hierdie studie verken die ervaringe van beraders verbonde aan LifeLine, Khayelitsha in Kaapstad. Nege-entwintig beraders is individueelonderhoude mee gevoer en het aan fokus groepe deelgeneem. Resultate ondersoek die berading opleiding en aktiwiteite; die problematiese aspek van berading; wat die berader help om klaar te kom; en die algemene impak wat berading het op die lewe van 'n berader. Die resultate onthul die moeilike en dikwelse stresvolle aspek van berading met HIV en VIGS pasiënte. 'n Aantal aspekte wat die pasiënte mee toe doen kry so wel as kulturele en werksplek faktore kan sake vir die berader beïnvloed. Verder kan die aard van die siekte en die probleme wat die siekte vir die pasiënt veroorsaak lei tot angs vir die berader ten opsigte van sy ofhaar eie verlede. Die resultate onthul verskeie tekortkominge tot 'n individueeie kliëntgesentreerde berading. Die studie beslus dat psigodinamiese probleme dalk deel moet vorm in die berader se opleiding, asook verder ondersoek moet word in gewone berader toesighouding.

This study was an outcome assessment of how well "Lifeline", a transitional shelter for women and their children, has been fulfilling its stated mission. It was also a program evaluation in terms of learning what former residents of Lifeline think about the quality and the importance of Lifeline's program.

Scandinavian rock carvings can be described as the special rock art languages that were written by prehistoric humans to express their ideas, beliefs and thoughts. Each piece of figurative motif language might tell a prehistoric story about for instance domestic life, social practice, ritual or cosmology. Among different motifs such as ship, human and animal, the wheel cross has received comparatively less attention. The wheel cross has many different variations, where the motif’s ambiguity and possible changing relations to other motifs as well as its relation to the rock itself and landscape over time, have not been studied in greater detail. To fill this gap, this work is aimed at investigating the multiple expressions and possible meanings of the wheel cross motif over time in South Scandinavian rock carvings. Two case study areas with rich rock carvings, Tanum and Enköping, located in the southwest and southeast of Sweden, respectively, are selected. The rock carving materials where the wheel cross motif is present are processed by chorological and chronological studies. A simple and general method is proposed to reconstruct the prehistoric shoreline of Scandinavia. The chronology of the wheel cross motif is analysed with stylistic and shoreline dating methods. The results of the chronological study are then analysed in a cultural-historical-geographical context using an intercontextual interpretation and comparative analysis method. It is suggested that the various visual expressions of the wheel cross, such as the wheel of a wagon or as the shield covering a human torso, have unique symbolic meanings beyond their practical and physical counterparts. With a cosmological meaning as the sun, and a religious meaning as a god, the wheel cross becomes the symbol of moving, fertility, power and life, which has been integrated into not only the rituals but also the domestic life of South Scandinavian society. Although the wheel cross motif is limited in number, its various forms, relating to other motifs, are argued to reflect how the Bronze Age society of Scandinavia imported and developed ideas, artefacts, stories, etc., from foreign cultures in Continental Europe and the Mediterranean area. Like the spoke physically supporting the cart, the wheel cross acts as the lifeline that closely links the landscape, ritual, artefact, human, and other materialities, to mentally support the South Scandinavian society. / Skandinaviens hällristningar kan på ett sätt beskrivas som ett slags språk, som ristats i berg av förhistoriska människor för att uttrycka till exempel idéer, social praxis, övertygelser och tankar. Varje figurativt motivspråk kan sägas framföra en förhistorisk berättelse om exempelvis det vardagliga livet, ritualer och/eller kosmologier. Bland olika motiv som skepp, människor och djur har det motiv som oftast kallas hjulkors jämförelsevis fått mindre uppmärksamhet. Hjulkorset finns i flera olika utföranden, och just motivets flertydighet i kombination med en studie av motivets relation till andra motiv, själva berghällarna samt plats i landskapet, har inte studerats detaljerat i någon större utsträckning. För att råda bot på denna kunskapsbrist syftar detta arbete till att undersöka motivets flerfaldiga uttryckssätt och möjliga betydelser i södra Skandinavien. För syftet har två fallstudieområden valts i Sverige, vilka bägge har rikligt med hällristningar. Den ena området är Tanum, beläget i sydvästra delen av Sydskandinavien, och Enköping, beläget i dess sydöstra del. Hällristningslokaler där hjulkors förekommer analyseras på flera sätt. En korologisk och kronologisk görs. En enkel och allmängiltig metod utvecklas vidare för att rekonstruera Skandinaviens förhistoriska strandlinjer. Kronologin för hjulkors utförs bland annat utifrån en stilistisk metod och en strandlinjedateringsmetod. Resultaten från den kronologiska studien analyseras sedan i ett kulturhistoriskt-geografiskt sammanhang med användande av en interkontextuell tolkningsmetod och en jämförande analysmetod. Det föreslås att de olika visuella uttryck i vilka hjulkors förekom, såsom exempelvis i form av vagnshjulet, eller i form av en sköld som täcker en mänsklig överkropp eller torso, har unika symboliska betydelser, utöver sina praktiska och fysiska motsvarigheter. Med en kosmologisk betydelse som solen och en religiös betydelse som gud, blir hjulkors-motivet en möjlig synonym för rörelse, fruktbarhet, makt och liv. Som sådan har den inte bara integrerats i ritualerna utan också i det vardagliga livet i de sydskandinaviska samhällena. Även om hjulkorsen är begränsade i antal, kan deras olika former och relation till andra motiv visa aspekter av hur bronsåldersamhället i Skandinavien importerade och utvecklade idéer, artefakter, berättelser och annat från främmande kulturer i Kontinentaleuropa och Medelhavsområdet. Liksom korset i betydelsen ekrar fysiskt stödjer ett vagnshjul fungerar hjulkorset även som en typ av livslinje som kopplade samman en mängd relationella företeelser, som var nödvändiga för det sydskandinaviska samhällets funktion på en mängd nivåer, exempelvis landskapet, ritualerna, artefakterna, människorna och förstås alla dessas samskapande och samverkande materialiteter.

This study aims to investigate the rationalization behind young adults' decision on whether or not they want children. The goal is to help contribute to previous studies on how reproductive mindsets differ based on whether or not a person wants children. This is a qualitative study rooted in interviews with eleven women and one man all aged 19 to 31 years of age. The theories used to analyze the results are concentrating on the terms expected lifeline, biological destiny, self-fulfillment, active mothering and intense mothering.  The results of this study show that the personal definitions of "success" in life do not differ drastically based on the desire to have children. Additionally, the informants all had similar expectations of what was "needed" from life,  in a financial sense, to achieve desired living conditions before having children. What did matter was what a person found self-fulfilling and their self-image in determining their desire for children. The results also show that the informants had experienced similar interactions with the pressures of societal norms on expected lifeline and that they worry about not living up to the notion of what a good parent is like.

Water distribution systems, electrical power transmission systems, and other civil infrastructure systems are essential to the smooth and stable operation of regional economies. Since the functions of such infrastructure systems often are inter-dependent, the systems sometimes suffer unforeseen functional disruptions. For example, the widespread power outage due to the malfunction of an electric power substation, which occurred in the northeastern United States and parts of Canada in August 2003, interrupted the supply of water to several communities, leading to inconvenience and economic losses. The sequence of such failures leading to widespread outages is referred to as a cascading failure. Assessing the vulnerability of communities to natural and man-made hazards should take the possibility of such failures into account. In seismic risk assessment, the risk to a facility or a building is generally specified by one of two basic approaches: through a probabilistic seismic hazard analysis (PSHA) and a stipulated scenario earthquake (SE). A PSHA has been widely accepted as a basis for design and evaluation of individual buildings, bridges and other facilities. However, the vulnerability assessment of distributed infrastructure facilities requires a model of spatial intensity of earthquake ground motion. Since the ground motions from a PSHA represent an aggregation of earthquakes, they cannot model the spatial variation in intensity. On the other hand, when a SE-based analysis is used, the spatial correlation of seismic intensities must be properly evaluated. This study presents a new methodology for evaluating the functionality of an infrastructure system situated in a region of moderate seismicity considering functional interactions among the systems in the network, cascading failure, and spatial correlation of ground motion. The functional interactions among facilities in the systems are modeled by fault trees, and the impact of cascading failures on serviceability of a networked system is computed by a procedure from the field of operations research known as a shortest path algorithm. The upper and lower bound solutions to spatial correlation of seismic intensities over a region are obtained.
