- Description: M.Cur. , In the out-patient section of the Adolescent Unit at Tara, The H Moross Centre, certain problem areas were identified. In this section, adolescents with mostly behaviour problems are evaluated and where necessary, family therapy service is rendered or the patient may be admitted depending on the type and severity of the problem. The problems experienced in this section became very pressing due to the uneven ratio between the demand for the service and the availability of staff. At the centre of these problems lies the issue of resistance in the family towards change, resulting in broken appointments and premature termination of therapy. A lot of time is also wasted by faulty referrals and data gathering 1s in itself, very time-consuming. A new nursing need emerged out of these problems. Firstly, the emotional preparation of the family and, secondly, as part of her role as member of the therapeutic team, to gather relevant data which will aid the development of an adequate diagnosis of the family. A post was created on an experimental basis for the nurse to conduct an initial interview with families at home. At the same time it was decided to evaluate the effectiveness of this home visit through an empirical study to justify this service.

- Description: M.Ed. , This study forms part of a comprehensive research project concerning teacher competence and its evaluation. A pilot study had been completed by lecturers from the Education Department at Rand Afrikaans University in 1994/5. An analysis of the data identified eight factors linked to teacher competence. These are: * The learning environment * Professional commitment * Order and Discipline * Educational foundation * Teacher reflection * Co-operative ability * Effectiveness * Leadership In addition to the above, five factors concerning the person evaluating teacher competence were identified. These are: * Invitational feedback * Transparent feedback * Tactful feedback * Credible feedback * Culturally sensitive feedback This research essay is part of the research undertaken on tactful feedback provided by educational managers during teacher evaluation. Tactful feedback has been conceptualised to consist of the following four aspects, namely: clarity, motivation, approach and openness (Bell, 1988:176-177; Montgomery & Hadfield, 1989:105-107). This particular research paper, therefore, focuses on the aspect of clarity in tactful feedback and its implication for the management of teacher competence. In view of the preceding brief introduction, the motivation for this study will be discussed.

- Description: M.A. (Clinical Psychology) , Adult religious conversion is an atypical religious experience with multiple social and psychological meanings for the convert. Four adult religious converts were interviewed to explore and describe their perspectives of their interpersonal relationships during the conversion process. These transcribed interviews were analyzed using thematic analysis within a case study design from a Critical Realist paradigm. The converts viewed conversion as a path to a preferred way of life with nine themes identified (romance with the religiously wayward, esteem for a religious sage, acceptance, gaining a new religious family, new religion aids relationships, life transitions, commonality maintains alt-religious relationships, diverse family dynamics, and altreligious relationships ending). Further interpretation integrated these themes within three relational processes that engage religious conversion through disrupting the convert’s religious status quo, maintaining relational stability conducive to conversion, and attracting the convert toward the new religion. These relational dynamic processes explore the texture and express the subtleties of relationships during the religious conversion process.

It is imperative that government uses gender sensitive policy instruments to reverse these imbalances. Gender expenditure analyses on national budget votes reveal a perpetuation of gender inequality. This municipal study assesses Johannesburg’s water budget process using an analytical framework of three criteria: representation; participation and benefit accrued to women. It determines that administrative representation of women in Johannesburg Water is nominal, the drafting of the budget remains patriarchal and representation of gender concerns for water provision in the consultation phase is not evident. The participation of women in the consultation and approval phases cannot be quantified. Women benefit minimally as employees and as entrepreneurs. This study determines that there is a potentially significant gendered impact of Johannesburg’s water budget, which motivates for this policy instrument to be gender sensitive. , Mr. H.

- Description: M.Sc. (Physics) , Silicon thin films can be manufactured with the aid of various deposition techniques, each with its own unique properties. In this study the optical properties of silicon manufactured with physical vapour deposition from an electron beam source were studied as a function of layer thickness, deposition rate and substrate temperature. The index of refraction (n and k) as well as optical gap eg. were determined with the aid of characterization models derived specific for optical techniques. These models are covered extensively in the thesis. It was found that the layers were homogeneous and stable, but that the deposition rate and substrate temperature did have a large influence on the properties of the layers. The results show that structural changes, first from the collumnar structure to an amorphous structure and with a further increase in substrate temperature, also a transition from the amorphous to a microcrystalline structure do occure at temperatures considerably lower than what was previously anticipated. With variations in deposition rate it was found that the disorder in the coating will increase with an increase in rate resulting in a reverse transition from the microcrystalline structure to the amorphous structure. Optical gaps in the range 1. 12eV to approximately 1. 38eV were found to be possible with the correct choice of deposition parameters...

- Description: In this study the problematic aspect of divorce and remarriage in the christian church is researched. Exceptional emphasis is laid on the policy of the Apostolic Faith Mission of South Africa (hereafter: AFM of SA) in this regard and how it is enforced in practice. Unfortunately we have to face the reality of divorce in the church, and the fact that not only members, but also the pastor can get involved in divorce and remarriage. Up to now the church has not really been able to come to a clear conclusion on the most appropriate way to handle such a situation. The AFM of SA, as well as several other churches prefer to prevent such situations by implementing certain precautionary measures. In this study the relevant problem of divorce and remarriage will be researched using a Biblical-ethical approach. The Bible refrains from giving specific pastoral guidelines to be used by the church and its members in cases of divorce and remarriage. The Pharisees incorrectly interpreted Deut. 24:1-4 that divorce and remarriage is acceptable when a man gives his wife a divorce letter. Jesus however controverts this interpretation in Matt. 5:32 when He says that divorce and remarriage was established due to the hardness of the human hart. The biblical message is rather that God hates divorce (Mal. 2:16). Some exegetes believe that there are two “grounds” on which a person is entitled to a divorce. These “grounds” are based on Matt. 5:31 & 32 when adultery is committed, and according to I Cor. 7:15 when the unbeliever wishes to not continue with the marriage (known as malicious separation). In this study we would like to stress that the Bible does not give any grounds for divorce. One cannot argue that God hates divorce, and then give “grounds” on which divorce is acceptable. Reference is only made to circumstances which destroys a marriage. Such incidents also hold connections with incidents where the marriage is not in honor of God, and leaves space for sin to ruin lives. The marriage is now an instrument in the hand of evil which will consequently lead to more sin. In these last instances a point can be reached where the marriage does not exist in the eyes of God any more, and can be separated lawfully by means of divorce. It is of opinion that divorce should remain as last resort to a broken marriage. Reconciliation should always be the first option. When divorce has taken place, the parties involved may choose to remarry as the previous marriage is ruined before God. If a person, however, should get married while the marriage still exists before the Lord, adultery is being committed. This marriage will be interpreted as a deed of adultery, but it would not be biblical to view such a marriage as a state of adultery. Marriage is therefore not seen as something which can’t be annulled, as opposed to the Roman Catholic Church, who views marriage as a sacrament. Marriage is not an absolute establishment, and can break up under certain circumstances. In this study we found that different religions, Christian and non-christian, have diverse views about marriage, divorce and remarriage. Most Christian religions uphold monogamous marriages – a lifelong binding between one man and one woman. Non-christians such as the Muslims believe in polygamous marriages where a man is allowed to marry four wifes at any given stage. Divorce is viewed as “allowable” on certain grounds by most religions. The Roman Catholic Church, as mentioned, differs in that the marriage is viewed as unbreakable. Nowadays an annulment is granted easier which allows remarriage to occur more often. In case of the AFM of SA, there are no clear guidelines on how divorce of a congregation member or pastor should be handled. Direction in this regard is however given by knowledgeable persons in the church. In earlier days, strict - mostly undocumented - guidelines have been followed in handling divorce and remarriage cases of pastors in the AFM. The person was found guilty because of his divorce status and was asked to resign from the ministry. In later years cases were handled on merit. Policies were enforced by means of disciplinary action following a church court’s ruling. Due to churches being reluctant to discipline members getting divorced and / or remarried, it seems as if members perceived divorce not as a serious sin, and to justify their act. The “guilty” party must be disciplined. The innocent party must be allowed to continue with his/her service in the ministry. The Bible teaches us that after sin was confessed to God, He unconditionally forgives and removes our sins, and never thinks about it ever again (1 John 1:9; Psalm 103:12). Divorce however, is perceived by the church to be a bigger sin and that divorced persons are second hand christians. This is especially true in case of a divorced church leader. Although the church, and specifically the AFM, strives to implement an acceptable policy relating to divorce and remarriage, most churches have not investigated the fundamental theory as yet. It seems as if churches are sensitive in compiling, or can not reach consensus on the theory. The AFM has a basic course called “Ethics – Divorce & Remarriage” being presented by Dr. F.P. Möller (jnr) in their Theological Seminary. The researcher of this study is a pastor in the AFM of SA who has experienced divorce and remarriage himself. The way the case was treated by the church and colleagues proved that the church did not follow biblical guidelines in dealing with a divorced pastor. His experience motivated him to conduct the mentioned study. The church should pick-up, and care for divorced members (in a biblical sense) as the good Samaritan or the shepherd leaving 99 sheep to search for 1 missing one to pick him up and caringly bring him back to the flock. The study is concluded with a theory that can be used by the AFM of SA. , Dr. F.P. Moller

- Description: M.Sc. , The statistical proof that most forms of cancer metastasize to bone has redirected the focus of secondary bone cancer to probe into the most efficient forms of treatment. Due to the fact that secondary bone cancer delocalizes to bone, chemotherapy has been established as an efficient form of treatment. Bisphosphonates is one chemotherapeutic agent that has shown a great potency in treating bone related sicknesses. Bisphosphonates are analogues of pyrophosphates that are characterized by the presence of two P-C bonds. They have a very high affinity for bone undergoing renewal and are thus able to inhibit tumour induced resorption. Bisphosphonates’ efficiency is however reduced due to that they have a low molecular weight hence are excreted before reaching targeted sites. In this study, an attempt to improve the efficiency was done by providing carbon nanotubes (which were synthesized in our laboratories) as delivery systems. By conjugating bisphosphonates onto carbon nanotubes the molecular weight was increased. Bisphosphonates conjugated carbon nanotubes have been radiolabelled to increase their anticancer activity. By exploiting the Enhanced Permeability Retention (EPR) effect and the high energy electrons from the radioisotope (³²P), it is anticipated that bone metastasis will be successfully treated by the ³²P labelled bisphosphonates carbon nanotube conjugates. Successful synthesis of bisphosphonates conjugated carbon nanotubes was confirmed by several characterization techniques namely: the Scanning Electron Microscope (SEM), Transmission Electron Microscope (TEM), Raman spectroscopy, Thermal Gravimetric Analysis (TGA), Electron Dispersive X-ray (EDX), and the Fourier Transmission Infrared spectroscopy (FT-IR). Oxidation and bisphosphonates conjugation onto carbon nanotubes were further confirmed by the Raman, TGA, FT-IR, EDX and the SXPS (Scanning X-ray photoelectron spectroscopy) Successful radiolabelling was determined by a liquid scintillation counter (LSC).

- Description: D.Comm. , Strategic management is a concept that is interpreted in many different ways in business. Banks have all subscribed to the process, but to various levels of application. In a highly competitive market and with the ever changing needs of customers, top management of banks have to utilise all resources optimally through their strategic management processes. What has made the task of banks more complex and difficult is that they have to take risk into account, more particularly interest rate risk. The risk concept has to be integrated into a bank's activities to form an integral part of the strategic management process. How to practically deal with the strategic management process of a bank by taking risk into account, was dealt with. An insight was given into the important role that risk focused strategic management can play in a bank to gain a competitive advantage. The study was limited to the four major bank players within the banks and financial services industry in South Africa, being ABSA, FNB, Nedcor and SBIC. Risk management has had many shifts in focus during modern day banking. On the threshold of the twenty-first century the banking and financial services industry is faced with even greater challenges than before. The industry is in an ever larger global arena which is very competitive and highly regulated. Many large non-bank competitors, that are well equipped with similar products and services, are entering this market. They have low barriers to entry as they have real advantages in that they have substantially less capital requirements and fewer regulatory constraints than those of the banking industry. A risk-based strategic business model was devised and developed by following a top-down approach to a firm. Models and theories were incorporated in this process. An organisation was broken down into activities, inherent risks identified, the levels of risk determined through the assessment of risk factors and elements, with the extent of control being determined. After having conceptually modelled the risk-based SBM, it was put to practice, more specifically for a bank. The risk-based strategic management model was then applied to a bank's strategic management process. The four different phases of the strategic management process, namely strategic information gathering, planning with formulation, implementation and control, were all dealt with. It was ascertained through interviews that all four of the major local banks had subscribed to strategic management, but applied it with different intensities. Strategic management, however, was still in an infant or start-up phase within the banking industry. In conclusion, the assessment of a bank's internal situation, by taking risk into account, will provide it with an objective view on its own capabilities. A competitive edge over its rivals can be obtained by taking calculated business risks and outcontrolling rivals.

- Description: Traditional mnemonic methods of teaching vocabulary in the Second Language (L2) classroom are not providing the students with sufficient vocabulary knowledge to facilitate effective communication, i.e. students do not use the words they have learnt for communication as textbook presentation and drill do not ensure student use of these same structures in the student’s own spontaneous expression (Savignon, 2000). The strategies to facilitate meaning-vocabulary1 learning as part of a wider outcome to teaching elements of functional communication in a multilingual society is not clearly defined in the Revised National Curriculum Statement (DoE, 2003). This research report set in a constructivist framework, will attempt to raise awareness in language teachers of a need to recognize the importance to facilitate meaning-vocabulary in L2 in OBE and collaborative learning. The aim of this research was therefore to find an effective strategy to facilitate collaborative L2 meaning-vocabulary learning to develop functional communication. The research question in this study was: * How can facilitators more effectively guide collaborative meaning-vocabulary learning to improve functional communication? Secondary questions to this study were: * Why do L2 facilitators not spend enough time on collaborative meaning-vocabulary learning? * What is the role of the facilitator in L2 collaborative meaning-vocabulary learning through communicative teaching strategies? * How should meaning-vocabulary be taught to ensure students acquire the ability to use the L2 critically and creatively in functional communicative situations outside the classroom? I have set my methodology in a qualitative paradigm, used an action research design, made use of interviews and interpreted the interviews to clarify the research topic by means of a ‘thick description’ (Henning, et al. 2004:142). The data used in this research were not only gathered from describing and analyzing the practices of the classroom community, but it also originated in real life classroom situations and both of these are characteristics of action research (Burns, 2000). I have used different data collection methods to ensure the validity of the findings and the recommendations. The methodology used to gather the data guided me to explore qualitative content analysis, grounded theory analysis and to a lesser extent discourse analysis. I have used these three methods to condense the data to find some meaning in the form to enable me to construct a theory around facilitating meaning-vocabulary learning, i.e. construct my own interpretive text. Qualitative content analysis was the basis for grounded theory analysis, while the discourse was dissected to find alternative proof for the findings. Some of the findings included guidelines which a teacher should keep in mind when facilitating meaning-vocabulary learning: 1. Know your students. 2. Keep meaning-vocabulary learning enjoyable – use different strategies when possible, but let them ‘construct’ their own knowledge. The students must ‘do’ something when they are learning meaning-vocabulary. 3. Encourage the students to use the words during functional communication exercises and essay writing. 4. Encourage the students to engage in their L2 inside and outside the classroom as often as possible, e.g. listen to radio, watch television, engage in conversation with friends or family in the L2. 5. Focus on meaning-vocabulary in communicative language. 6. Engage in conversation with your students as often as possible, not only about a theme or topic but also about their experiences and feelings in your classroom. 7. Use pictures to explain word meanings. Let them create their own images where possible. 8. Use the new meaning-vocabulary during discussions. , Mr. W.A. Janse van Rensburg

- Description: M.A. , Emergence of informal settlements on vacant lands in urban areas results from intuition and political decisions, and sometimes cultural background. So any available vacant land is used for settlement development and dwelling sites. An informal settlement named after Elias Motsoaledi, a political activist of the African National Congress (ANC), was developed in the south-western part of the city of Johannesburg in 1993. Motsoaledi informal settlement was established on a vacant piece of land where there are overhead power lines. Motsoaledi community members that have their dwellings in close proximity and even underneath overhead power lines are exposed to an environment that is surrounded by electrical magnetic fields (EMFs). There are no reported cases of biological and health consequences that have been caused by EMFs as yet. This study aims to focus on the health aspect of persons who have their dwelling in the vicinity of the overhead power lines in Motsoaledi. The high levels of EMFs around Motsoaledi is further excelerated by the zinc structures that are conductive to electricity and may result in electrocution for dwellers that are in the direct vicinity of overhead power lines. Longer exposure to athermal conditions may result in bio-effects and lead to changes in human health. Furthermore, effects from EMFs are possible electrocution, often causing immediate death of persons and destruction of property. Due to the lack of proper planning of informal settlements, such settlements become vulnerable to potential environmental hazards such as the destruction of structures. This study hopes to identify the plight of a particular informal settlement, namely, Motsoaledi as an isolated case to reflect dire conditions of most of the informal settlements around the country.

- Description: M.Tech. (Operations Management) , The research is about the application of lean manufacturing tool known as manufacturing kaizen in order to improve a work process at . The company is based in Kempton Park, South Africa, used as a case study to evaluate the benefit of manufacturing kaizen at a specific industrial concern. The research demonstrated how manufacturing kaizen when used appropriately can help APSAP PTY LTD to eliminate waste, have better inventory control, short process cycle times, and better overall financial and operational procedures. The goal was to reduce the identified waste using manufacturing kaizen tool. Waste reduction eventually reduced the cycle time of the work process. The primary objective of the thesis was to study and analyze the cylinder preparation process in APSAP PTY LTD. The process activities were captured, then analyzed using the process map. The secondary objective was to identify waste in the process. Major businesses in South Africa have been trying to adopt new business initiatives in order to stay competitive. One way to increase this is to apply proper manufacturing strategy and use of lean manufacturing or continuous improvement tools to achieve business objective which is to stay competitive and to increase profit. The research addresses the application of a lean manufacturing tool called manufacturing kaizen. Manufacturing kaizen refers to a technique used for improving a work process by the eliminating waste within that process in the organization. It is one of the improvement tools that focus on cost reduction by eliminating non-value added activities. Kaizen achieves the elimination of waste by empowering people with tools and a process to uncover improvement opportunities and make change. Participants are key aspect in implementing the manufacturing kaizen event, since they are the people directly involved. Identifying the key people that will be used in the manufacturing kaizen event is very crucial for the success of the event. Any changes or improvements of the process will have direct impact to the people. It is important that people who are directly affected by change become part of the process and feel empowered. Kaizen understands waste to be any activity that is not value adding from the perspective of the customer. The research unpacks manufacturing Kaizen and looks into its qualitative nature and its application within a working environment and how it influence productivity. It also investigates how this tool can be applied in a process or chemical industry and the benefits it can provide to an organization. The initial step in the approach was to outline data collected and examining techniques used to collect the data. The researcher carried out direct observation as he was physically present, and personally monitored what was taking place. The results show that labor productivity can be improved over time after the introduction of manufacturing kaizen. It concludes that with the introduction of manufacturing kaizen, transformation at workplace can be established leading to productivity improvement within an organization. The research has shown that with the proper use of manufacturing kaizen , waste reduction can be achieved.

- Description: M.Sc. , Mpumalanga, “the place where the sun rises”, sets the scene for one of the rarest wetland types in South Africa. They are formed on one of the last remnants of the ancient African land surface, contain peat and together with a variety of other pan types make up the Mpumalanga Lakes District. Of these approximately 320 pans, only ±2.3% are reed pans. These endorheic wetlands are unique from other pan types and peatlands in South Africa and support an abundant biodiversity. They perform vital functions such as water storage, filtering out impurities and carbon fixation, which prevents an excess release of CO2 into the atmosphere. There is very little known about these endorheic wetlands and thus they are constantly being threatened by various activities such as agriculture, livestock and mining. The objectives of this study were to determine the spatial and temporal variation of macroinvertebrate community structures of reed pans and the environmental factors, such as water quality, responsible for the maintenance of these structures; to determine the best method for sampling aquatic invertebrates in reed pans; as well as to determine the relationship between aquatic invertebrates and the water, sediment and habitat quality of a reed pan. Together with this the amphibian diversity as well as the occurrence of other biotic components was determined. Four reed pans were assessed during four different seasons over a one year period to account for the different hydrological extremes. Sub-surface water samples were analyzed for their suspended solid content, nutrient levels, metals and chlorophyll-a concentrations as well as in situ water quality parameters. Sediment samples were analyzed for metal concentrations, organic carbon and water content, as well as sediment size distribution. Invertebrates were collected using the following sampling techniques: aquatic light trap, terrestrial light trap, emergent trap, sweep net, plankton net, as well as benthic sampling using an Eckman grab.

The Christ story as a narrative substructure of the Pauline ethos.

- Description: Pauline theology and Pauline ethics have generally been placed in sharp antithetical contrast to each other. Such a dialectical tension has resulted in a lopsided understanding of the interrelationship that exists between these two components. It is therefore necessary to examine the relationship between Paul¡¦s theology and ethics by providing a basic (and selected) overview of each in an attempt to reconcile them. The interrelationship between these two components will be considered from a narrative perspective in an attempt to restore a sense of coherence within the broad spectrum of Pauline theology. Within Paul¡¦s theological framework several important and selected themes will be considered: „« The Centrality of the Gospel in Paul: It will be proposed that the gospel, understood as the story about Jesus¡¦ death and resurrection, fundamentally shapes and informs Paul¡¦s entire theological and ethical framework. It is the gospel that provides coherence to the Pauline corpus. „« Pauline Soteriology: The concern will be to show that Paul¡¦s understanding of salvation moves from the objective and historical reality of what was achieved in Jesus¡¦ death and resurrection to subjective appropriation. This is profoundly expressed in the variety of metaphors (picture words) Paul employs to speak about what is first and foremost an existential experience for the believer. „« Pauline Ecclesiology: The story of Jesus¡¦ death and resurrection expresses the reality that individuals are brought into an existential experience of salvation, but this is furthermore enhanced by the fact that such an experience is given meaning within the context of the ejkklhsia. The contention is that the church, as the community of faith, is the sphere wherein which individuals mature spiritually. „« Paul¡¦s Eschatological Vision: Christ's death and resurrection was an event of eschatological significance. It portended the end of one age and the beginning of a new age. Pauline eschatology brings into sharper focus the nature of community life and profoundly shapes Paul¡¦s ethological discourses. It is suggested that Paul¡¦s ethological reflections make sense only when understood as flowing out of his theological framework. Furthermore, an examination of Pauline ethics suggests that he persistently brings the gospel to bear on the various contingencies that he is confronted with. Paul¡¦s ethics centres on the cross of Jesus Christ, which functions metonymically to evoke, as the focus, the significance and meaning of the cross. For Paul, the cross and all that it embodies presents a call to cruciformity ¡V life in the pattern of the cross. It is proposed, by way of a theological exposition of 1 Cor. 11.17-34, that Paul¡¦s ethology is a result of an ongoing dialogue, he is engaged in, between the Christ event and the various ethical contingencies he is called upon to deal with. The gospel forms the basis of Paul¡¦s reflective discourses. It provides Paul with an undergirding narrative framework that shapes his worldview. A brief overview of the important role that worldviews perform will show that Paul responds to his communities of faith from the perspective of worldview. That is, Paul is concerned to shape the behaviour of his Christian converts by sculpting their particular frames of reference. The frame of reference he seeks to inculcate within the lives of his converts is based on the story of Jesus Christ. It is this story that becomes paradigmatic for the ethos Paul seeks to set up. Furthermore, it is suggested that it is possible to trace the narrative contours of Paul¡¦s reflective discourses. Such a suggestion is supported by showing that 1 Corinthians as a whole resonates with echoes of a narrative; a narrative that is rooted in the Christ event. The mapping out of these narrative contours in Paul¡¦s letters will reflect the centrality of the gospel story. Moreover, it is suggested that by tracing the narrative substructure present in 1 Cor. 11.17-34, that the reader will gain a deeper appreciation of how the gospel functions within Paul¡¦s theological and ethical framework. Finally, it is proposed that Paul¡¦s reflective discourses shape and conform his ethos in such a way as to provide a meaningful framework out of which he calls the community of faith to live out its witness. In so doing, Paul emphasises the importance of remembering (recalling) the stories that constitute the Christian worldview. , Prof. JA Du Rand

This is profoundly expressed in the variety of metaphors (picture words) Paul employs to speak about what is first and foremost an existential experience for the believer. „« Pauline Ecclesiology: The story of Jesus¡¦ death and resurrection expresses the reality that individuals are brought into an existential experience of salvation, but this is furthermore enhanced by the fact that such an experience is given meaning within the context of the ejkklhsia. The contention is that the church, as the community of faith, is the sphere wherein which individuals mature spiritually. „« Paul¡¦s Eschatological Vision: Christ's death and resurrection was an event of eschatological significance. It portended the end of one age and the beginning of a new age. Pauline eschatology brings into sharper focus the nature of community life and profoundly shapes Paul¡¦s ethological discourses. It is suggested that Paul¡¦s ethological reflections make sense only when understood as flowing out of his theological framework. Furthermore, an examination of Pauline ethics suggests that he persistently brings the gospel to bear on the various contingencies that he is confronted with. Paul¡¦s ethics centres on the cross of Jesus Christ, which functions metonymically to evoke, as the focus, the significance and meaning of the cross. For Paul, the cross and all that it embodies presents a call to cruciformity ¡V life in the pattern of the cross. It is proposed, by way of a theological exposition of 1 Cor. 11.17-34, that Paul¡¦s ethology is a result of an ongoing dialogue, he is engaged in, between the Christ event and the various ethical contingencies he is called upon to deal with. The gospel forms the basis of Paul¡¦s reflective discourses. It provides Paul with an undergirding narrative framework that shapes his worldview. A brief overview of the important role that worldviews perform will show that Paul responds to his communities of faith from the perspective of worldview. That is, Paul is concerned to shape the behaviour of his Christian converts by sculpting their particular frames of reference. The frame of reference he seeks to inculcate within the lives of his converts is based on the story of Jesus Christ. It is this story that becomes paradigmatic for the ethos Paul seeks to set up. Furthermore, it is suggested that it is possible to trace the narrative contours of Paul¡¦s reflective discourses. Such a suggestion is supported by showing that 1 Corinthians as a whole resonates with echoes of a narrative; a narrative that is rooted in the Christ event. The mapping out of these narrative contours in Paul¡¦s letters will reflect the centrality of the gospel story. Moreover, it is suggested that by tracing the narrative substructure present in 1 Cor. 11.17-34, that the reader will gain a deeper appreciation of how the gospel functions within Paul¡¦s theological and ethical framework. Finally, it is proposed that Paul¡¦s reflective discourses shape and conform his ethos in such a way as to provide a meaningful framework out of which he calls the community of faith to live out its witness. In so doing, Paul emphasises the importance of remembering (recalling) the stories that constitute the Christian worldview. , Prof. JA Du Rand

- Description: M.Sc. , At present large scale extensive cropping of fish populations of impoundments is being undertaken by the agricultural departments of the government of the Republic of Venda and selfgoverning states of Lebowa and Gazankulu. Parasitological surveys coinciding with the cropping program revealed that Clarias gariepinus (Burchell, 1822) and Oreochromis mossambicus (Peters, 1852) were infested by fish lice of the genus Dolops (Crustacea: Branchiura). A study was therefore initiated to examine the extent of these infestations and other impoundments in Transvaal were also included. A total of 14 localities in Transvaal extending from Bloemhof Dam in the Southwest to Luphephe and Nwanedzi Dams in the Northeast were surveyed during 1982 and 1983. At these localities fish were collected by means of gill nets, seining and electrofishing techniques. The collected fish were examined in a field laboratory at the collection localities for the presence of ectoparasitic Dolops. The fish were weighed and measured and the site of attachment of the parasites, if present, were recorded. The parasites were removed and fixed in either hot formalin or AFA. A number of parasites were transported alive to the laboratory in Johannesburg where they were kept in glass aquaria and their life cycle studied. A morphological description based on light microscopy as well as scanning electronmicroscopy of the eggs, larvae and adults were made, and comparative body dimensions of parasites from various localities recorded. It was found that only one species of Dolops that is D. ranarum (Stuhlmann, 1891) occurred in Transvaal. This parasite was found in only five of the 14 examined localities of which all were situated in Northern Transvaal, north of the watershed.
