Adolescents have become focal points of discussions and debates regarding sexuality and reproductive health matters. However, little research has been done particularly in South Africa to examine their knowledge concerning abortion and emergency contraception. Research indicates that a substantial proportion of adolescent pregnancies are unintended or unwanted. Abortion and emergency contraception are both time-sensitive services. Thus having accurate and comprehensive knowledge about both abortion and emergency contraception is pivotal, in the case of unintended or unwanted pregnancy or when engaging in unprotected sex or experiencing contraceptive failure that could lead to pregnancy. The 1994 International Conference on Population and Development (ICPD) defined reproductive health rights for both men and women as the right to "decide freely and responsibly the number, spacing and timing of their children and to have the information and means to do so" (p. 60). That is, men and women should "have the right to make decisions concerning their reproduction free of discrimination, violence and coercion" (ICPD, 1994, p.60). Based on these definitions, it is rather evident that comprehensive and accurate knowledge are at the core of one's ability to make an informed consent. This is confirmed by Adler's (1992, p. 289) definition of informed consent or choice "a) access to sufficient information b) understanding the information c) competence to evaluate potential consequences d) freedom to make a choice and e) the ability to make and express that choice". It is from this framework that this study emerged. The aim of this study was to examine adolescents' knowledge concerning abortion and emergency contraception. The participants were Grade 11 learners between the ages of 15-24 years from five different schools in the Buffalo City Municipality. A sample of 514 was achieved. Data were analysed using descriptive cross-tabulation, chi-square and qualitative methods where appropriate. The results revealed that most of the participants did not have sufficient accurate knowledge concerning the Choice on Termination of Pregnancy Act, consequences of legal abortion and emergency contraceptive pills to make informed decisions. Furthermore, data also revealed that the participants' schools playa role in their sexual activity, their knowledge about the Choice on Termination of Pregnancy Act and about emergency contraceptive pills. Although this method made it feasible for the researcher to make general assumptions, non-responses were one of the limitations of the study. Similar research in various municipalities/cities in and outside the Eastern Cape is recommended so as to increase further awareness concerning the level of knowledge that adolescents have about contraceptive pills particularly emergency contraceptive pills, the Choice on Termination of Pregnancy Act and abortion in general.

Globally, ecosystems provide services of almost twice the value of global gross national product (Costanza et al., 2006). The Buffalo City Municipality (BCM), South Africa contains biodiversity of national and international importance (Pierce, 2003; Pierce et al., 2005). Despite this, the municipality continues to experience loss of both urban and rural biodiversity (Buffalo City Municipality, 2006a). This study sought to determine the status of biodiversity, and the potential for ecosystem services to contribute to conservation, within the BCM. Biodiversity features, including ecosystem type, species of special concern and biodiversity processes, were identified and mapped using a GIS to produce a biodiversity priority index for the BCM. Current transformation status was then mapped to determine the level of ecosystem degradation within the BCM. Priority biodiversity areas as well as individual biodiversity features were spatially overlain against current transformation status and protected areas and analysed using a GIS to determine the level of degradation and protection of BCM biodiversity. In total 3.5 % of total BCM biodiversity was protected. Of the 24 ecosystem types, 11 (45%) had less than 1% under protection, while 16 (67%) had less than five percent protected. Not restorable areas, thus completely lost to biodiversity conservation, comprised just less than a quarter of the total BCM area while un-impacted areas comprised just 12.3%. Twenty five ecosystem services were identified as being provided by intact natural ecosystems within the BCM. The natural capital providing these services was identified and mapped to produce an ecosystem service index (ESI) using a GIS. This ecosystem service index and the biodiversity priority index were overlain to determine their level of correlation. Overall ESI correlation with priority biodiversity was weak although several individual ecosystem services, including carbon sequestration, showed correlation. Using the above data layers an implementation plan and conservation framework was proposed to assist the coordination of local conservation action within the BCM. It is concluded that ecosystem services are a potentially useful tool for conservationists at the local level seeking to ensure that biodiversity has relevance to and receives protection from broader society.

In terms of the South African Government Structure, Local Government is entrusted with the service delivery mandate. Furthermore, Local Government, being the closest sphere of government to the people, is expected to enhance service delivery to the communities within its jurisdiction. Local Government has for the past four years, undergone numerous transformation processes, ranging from Local Authorities, to Transitional Local Councils and to Municipalities. Having mentioned that, Buffalo City Metropolitan Municipality, in particular, has recently acquired metropolitan status, which requires another transformation protocol. At the same time this automatically raises the bar on the service delivery expectations by the communities. In general, Local Government has been extensively supported by the National and Provincial Governments to deliver superior services to communities. This has happened through numerous pieces of legislations such as the Municipal Structures Act 117 of 1998, the Municipal Systems Act 32 of 2000, the Municipal Finance Management Act 56 of 2003 and the Constitution of the Republic of South Africa, act 108 of 1996. In 1997, the South African Government introduced a White Paper on the Transformation of the Public Service. This was to re-emphasis on the performance enhancing role of both the political and administrative leadership in the implementation of service delivery mandates. The need was identified that communities require an assurance that their needs are taken care of by the leadership of the municipalities. It is therefore the role of leadership to ensure effective implementation of service delivery initiatives and to promote a culture of performance among the administrative officials of the municipality. The aim of this study is to critically investigate the role of leadership: A case study of Buffalo City Metropolitan Municipality (BCMM), with the view that BCMM is considered one of the high capacity municipalities within the Eastern Cape Province. During the literature review, it became evident that different people and scholars, dating back in the early 90’s, view leadership in different forms. In sourcing the information for this research, structured interviews were conducted with five Directors, five Executive Mayoral Councillors and five Ward Councillors. The interviews were an extensive consultation process which resulted in over 30 hours of engagement with research participants, with an average of 2 hours per structured interview. A four week period was allocated and effectively utilised for this exercise. The research provides recommendations for further research on other related components of the subject such as the intended role as compared to the current role fulfilled by both administrative and political leadership, and suggested solutions to the current problems in Municipalities, in order to ensure their sustainability within Local Government. The research findings identified the need for the leadership to take the leading role in service delivery initiatives in order to address the service delivery challenges in local government. Political leadership need to enhance the public participation process to ensure the community is on board regarding the progress of their respective projects and planning processes.

This research is about the life and material conditions of existence of Xhosa people living in three informal settlements of East London (now part of Buffalo City) in South Africa. Most observers see such unplanned settlements as a radical shift away from the groups' traditional rural homestead, some describing them as "neo-vernacular" since---like the vernacular dwelling---these are built from the materials coming from the surrounding environment. The research went beyond this perception and rather proposed that despite changes in the building forms, materials and techniques, the informal Xhosa urban settlements are still---consciously or not---governed by Xhosa traditional rules. / To demonstrate this hypothesis, the study attempted to understand the culture of the group through the review of the literature dealing with the Xhosa life and customs in the group's traditional rural setting. Then, it established the evolutionary process of the Xhosa architecture, which was also (re)integrated not only in the history of South African architecture but also in the whole architecture history's continuum. Next, followed the description of the elements that have been found in the three informal settlements as well as in the dwellings and plots that have been selected for the case study. Finally, from the comparison between the elements found in the three squatter settlements selected and the traditional Xhosa setting it is concluded that the traditional Xhosa culture has survived in the three informal settlements of East London. Its persistence has been confirmed in the rituals and everyday activities, the objects, spaces and buildings created, as well as in the way they are constructed, used or lived in.

This study investigated the role of selected ward committees 29 and 32 of Nompumelelo and Tsholomnqa respectively in the Buffalo City Municipality (BCM) in enhancing basic service delivery. In terms of the White Paper on Local Government (1998:4), developmental local government promotes a system that centres on working with local communities to find sustainable ways to meet their needs and improve the quality of their lives. The study on that basis examines the nature and extent to which wards 29 and 32 committees enhanced basic service delivery within BCM. The study is premised on the assumptions that: The involvement of party-elected Councillors in ward committees inhibits members of ward committees from playing an active role in their communities; Ward committees are not clearly communicating municipality programmes to their communities; BCM is biased in favour of urban wards in service delivery; If the committees of wards 29 and 32 were given more powers to play a much wider role in providing leadership and make decisions in their communities (being elevated from an advisory role to ward management structures), they would make an impact in enhancing basic service delivery; and, With additional decision-making powers ward committees could play a more effective role in local government matters. The perceived slow pace of service delivery by municipalities has resulted in growing impatience and dissatisfaction, in particular among poor communities. This has been demonstrated by the spontaneous protests and unrests directed at municipalities that have been taking place nationally since 2003. The uprisings explain two aspects, namely local government is considered by communities to be the delivery arm of government in South Africa and poor communities feel betrayed because their active participation in government-provided spaces for participation such as municipal elections, ward committees and IDPs did not yield the result of promised development (Theron, 2008:36). iv The study employed the qualitative research design using an interview survey as a method of data collection and the reviewing of existing study material and documents to test the validity of the afore-mentioned assumptions. Lastly, with the aim of assisting BCM in nurturing the potential of ward committees operating in its area of jurisdiction, the following recommendations based on the findings of the study are made: BCM considers subjecting ward committees to structured formal and accredited training; BCM delivers services in a legally compliant manner; BCM delegates sufficient powers to ward committees; Ward committees be trained together with officials that drive the CBP process when BCM starts implementing the process; and, BCM provides support to ward committees.

Orientador: Maria Elisabete Jorge Amaral / Banca: Eliana Morielle Versute / Banca: Humberto Tonhati / Resumo: Nesse trabalho apresentamos o primeiro mapa comparativo do cromossomo 6 do búfalo de rio (BBU6), desenvolvido a partir da utilização de um painel de células somáticas híbridas irradiadas búfalo-roedor com fragmentação de 5000 rads. O mapa preliminar construído é composto por 33 marcadores, os quais estão ordenados em dois grupos de ligação compostos por 12 microssatélites, 19 genes codificantes e duas ESTs. A freqüência de retenção observada entre os marcadores variou de 14.4% a 40%. A ordem dos marcadores dentro dos grupos de ligação do BBU6, em sua maioria, é consistente com o mapa RH bovino. Esse mapa preliminar do BBU6 é um ponto de partida para comparar a ordem dos genes entre as espécies, fornecendo uma oportunidade para estudar micro-arranjos nesse cromossomo, além de possibilitar a clonagem posicional em búfalo de rio. / Abstract: We present the first radiation hybrid map of BBU6 developed from a recently constructed river buffalo whole-genome radiation hybrid panel (BBURH5000). The preliminary map contains 33 cattle-derived markers, including 12 microsatellites, 19 coding genes and two ESTs, distributed in two linkage groups. The retention frequency of individual markers ranged from 14.4% to 40.0%. Most of the marker order within the linkage groups is consistent with the cattle RH maps. This preliminary BBU6 RH map is the starting point for comparing gene order between both species, presenting opportunity for examination of micro-rearrangements of these chromosomes and, thereby enhancing the possibility of positional candidate cloning in river buffalo. / Mestre
