Groundwater resource evaluation and protection in the Cape Flats, South Africa

Segun Michael Adegboyega Adelana January 2010 (has links)
<p>The analysis of geologic, hydrologic and hydrogeologic data interpreted to give the characteristics of the Cape Flats aquifer showed the quality of groundwater from the aquifer is suitable for development as a water resource. The conceptual model of the Cape Flats sand shows an unconfined sandy aquifer, grading into semi-confined conditions in some places where thick lenses of clay and peat exists. Recharge rates through the saturated zone of the Cape Flats aquifer have been determined by water table fluctuation (WTF), rainfall-recharge relationship, soil water balance and chloride mass balance methods (CMB). Recharge rates using the WTF vary considerably between wet and dry years and between locations, with a range of 17.3% to 47.5%. Values obtained from empirical rainfall-recharge equation (method 2) agree with those of the WTF. Recharge estimates from the water balance model are comparatively lower but are within the range calculated using empirical method 2 (i.e. 87 &ndash / 194 mm or 4 &ndash / 21% of MAP). These recharge rates also agree with estimates from the series of other methods applied to sites located in the north-western coast of Western Cape and are comparable to recharge rates obtained elsewhere in the world.</p>

A narrative of crystal methamphetamine: a case study of a young person’s experience of factors that leads to crystal methamphetamine use within a high-risk area in Cape Town

Jantjies, Janine Chernay January 2010 (has links)
<p>Recent research has indicated a significant increase in the crystal methamphetamine abuse in the Western Cape. The study aimed to provide an understanding of the interaction of the social and historical contexts in relation to the life experiences and perceptions of a young person residing in the Cape Flats. Primarily the study aimed to explore the factors that influenced the participant to use crystal methamphetamine. It adopted a social constructionist epistemological perspective and employed Bronfenbrenner&rsquo / s ecological systems theory as the theoretical framework. The subsystems of the ecological systems theory include the individual who is influenced by the microsystem, the mesosystem, the exosystem, the macrosystem and the chronosystem. This was a qualitative research study that&nbsp / employed an intensive case study. Data was obtained through series intensive semi-structured interviews that were approximately 40 - 70 minutes in duration. The participant is a coloured female, aged 28 years from a high-risk community in the Cape Flats. Prior to the interview process, relevant permission was obtained from the participant, which allowed the interviews to be conducted and recorded. The data was then analysed using a narrative analysis. The themes that emerged from the research findings include: childhood trauma / sexual abuse during childhood / social milieu and norms / adolescent delinquency / the cycle of abuse / understanding crystal methamphetamine use and the consequences of crystal methamphetamine use. Findings with regard to the individual factors included psychological well-being, depression and negative affectivity, feelings of hopelessness, suicidal ideations, loneliness, past abuse of legal substances, adolescence, delinquency and childhood sexual abuse. The influential factors that emerged within the microsystem were lack of family support, dysfunctional family dynamics, childhood abandonment, uninvolved parents, several custodial parents, childhood disequilibrium, parental modelling and family drug use. Further findings within the microsystem included peer influence viz. direct persuasion of drug use, peer exposure of drugs, experimentation, delinquent behaviour, gang-related involvement and peer group acceptance. The mesosystemic findings included, lack of emotional support or attachments, social support, lack of structure as well as relocating to numerous schools and homes. Findings located in the exosystem were the availability and accessibility of drugs in all the communities in which the participant lived. Findings in the macrosystem included the social environment of the individual, including the social norms of the community and the home setting as well as the norm of violence, crime and gangsterism. The information and knowledge accumulated would optimistically contribute to addressing the paucity of qualitative literature and present knowledge to&nbsp / improve intervention and prevention strategies.</p>

Multimodality and negotiation of Cape Flats identity in selected Daily Voice front pages

Matthews, Waseem January 2009 (has links)
<p>This thesis explores the social semiotic relationship of visual and verbal signs of the Daily Voice tabloid as a way to show how the social context influences meaning of the signs used in its multimodal frontpages. The Daily Voice tabloid largely uses Kaapse English/ Afrikaans as spoken by Coloureds on the Cape Flats on its frontpages rather than standard English or standard Afrikaans associated with White people. The study assumes that the meaning constructed by and through the verbal and visual signs on the Daily Voice frontpages is interdependent on the relationship the multimodal texts have with the largely Cape Flats readership. This study maintains the importance of the idea of the localisation of meaning in socio-cultural specific contexts throughout. I conclude that Kress and Van Leeuwen&rsquo / s (1996/2006) design could be extended beyond Westernised contexts and that marginalised discourses such as those unique to the Cape Flats are not static, but indeed dynamic. I also extend the appraisal theory by Martin and White (2005) to marginalised bilingual discourse and establish that Appraisal theory can be used to not only evaluate verbal discourse but also that visual discourse needs to be considered as a tool within the appraisal framework. I also conclude by suggesting a monolectal view of Kaapse English/Afrikaans discourse. That is, the meaning potential of Kaapse English/Afrikaans by Cape Flats speakers would be lost if perceived or analysed as emanating from two languages, (White) English and (White) Afrikaans. Therefore the conclusion is that the Daily Voice uses Kaapse English/Afrikaans as is used in Cape Flats socio-cultural contexts to construct meaning-making options across its frontpages.</p>

Höga trähus : Befintliga trähusproducenters förutsättningar och intresse att bygga flerfamiljshus med bärande trästomme med fler än två våningar / Wooden framed apartment buildings : Existing manufacturers of wooden framed buildings requirements and interest of building block of flats with bearing wooden frame with more than two floors

Gustavsson, Göran, Löfgren, Göran January 2008 (has links)
Syftet med uppsatsen är att undersöka befintliga trähusproducenters förutsättningar och intresse att bygga flerfamiljshus med bärande trästomme med fler än två våningar. För att nå vårt syfte har vi satt oss in i marknaden för höga trähus. Detta har vi gjort genom att initialt betrakta dels marknaden ur olika intressenters perspektiv, dels genom att undersöka företagen som finns på marknaden idag och placera in deras respektive byggsystem i en produktlivscykel. Vi har därefter satt oss in i marknaden för trähus och fokuserat på tio företag som vi har djupintervjuat. Vi beskriver sedan de samband vi ser mellan förutsättningarna på marknaden för höga trähus och intervjuresultaten. Dessa samband utmynnar i en analys av de faktorer som påverkar företagens val av strategi. Vi gör en uppdelning av företagen i olika strategiska grupper utgående från deras erfarenhet av höga trähus, och vi redogör för hur företagen i de olika grupperna kan agera vid några olika scenarier. Faktorer som påverkar är ägarförhållanden, övrig verksamhet i koncernen och bristen på ingenjörskompetens i projekteringen. I våra redovisade scenarier tror vi att flera av dagens trähusproducenter kommer att finnas på marknaden om fem år. Det gäller främst företag som är starka på projektverksamhet, men också företag som är underleverantörer av element. De företag som nu är på marknaden med ett byggsystem eller som nu är på väg in tror vi, i våra scenarier, har ett gynnsamt läge främst för leveranser till större och medelstora städer. / The purpose of this thesis is to investigate existing manufacturers of wooden framed buildings requirements and interest of building block of flats with bearing wooden frame with more than two floors. With this in view we have studied the market for high wooden houses. We have initially regarded that market from the approach of different interest parties and through investigation of the companies in the market today and to place their systems for building technologies in a life cycle for the product. After that we have regarded the market for wooden framed buildings and focused on the ten companies which we have interviewed. Than we describe how the requirements on the market for high wooden houses are related to results from the interviews. These connections end in an analysis of the factors which influence the choices for the strategy of the companies. We divide the companies in different strategic groups. These groups originate from their experiences of high wooden houses. We describe how the different companies can act at some different scenarios. Factors which influence the existing manufacturers of wooden framed buildings entrance on the market are the state of proprietions, the other activity in the group of companies and the lack of competence of engineering in the projecting. In the scenarios, which we have given details about, do we predict that several of todays existing manufacturers of wooden framed buildings will be on the market in less than five years. This is above all valid for companies which are strong in the activities of projects and companies which are subcontractor of building elements. The companies which are on the market now with a system for building technologies, or are on their way, we believe have a favourable position above all for deliveries to larger or mediumlarge cities.

Titel: ”Det ska inte vara något jävla fyllställe där man släpar hem folk och grejer” : En studie om hemlösa missbrukares syn på socialtjänstens gruppboenden i Gotlands kommun

Johansson, Markus, Jakobsson, Mats, Kotz, Jane January 2006 (has links)
Studiens syfte har varit att få kunskap om hemlösa klienters syn på sin boendesituation. Samt att få fördjupad kunskap om klienternas upplevelse av möjlighet till förändring och hur de beskriver att de bemöts och behandlas på Beroendeverksamhetens gruppboenden. En kvalitativ metod har använts för att besvara syftet. Det empiriska materialet består av intervjuer med sju personer som för närvarande bor på ett kommunalt gruppboende. Tolkningsramen har utgjorts av teorier och forskning kring förändringsprocesser och strategier för att motverka hemlöshet. Rollteori har också använts för att ge en djupare förståelse för interaktionen mellan individer och mellan individ och organisation. Resultaten visar att det är svårt att trivas på en institution. Det har mycket att göra med den maktstruktur som präglar en sådan inrättning. I studien framkom att det skapas motståndsstrategier för att värja sig i en sådan situation. Resultatet visar också att motstånd skapas när man inte känner sig delaktig i sin egen förändringsprocess. Det är viktigt för de boende att kunna påverka sin boendesituation. Boende som tycker de får hjälp på boendet anser att de kan använda vistelsen till något positivt. Personalens roll inskränker sig för de boendes del till att vara behjälpliga med praktiska saker, ett slags yttre förändring. Någon tycker att personalen även kan vara ett socialt stöd i en inre mening, att hjälpa de boende med strategier som gör att de kan fortsätta att leva ett drogfritt liv. Studien visar vidare att man både önskar mer av socialt stöd samtidigt som några upplever att man själv är det bästa verktyget i en förändringsprocess. Resultatet visar slutligen att institutionens strikta regler blir en viktig förändringsfaktor i klienternas liv. Kravet på drogfrihet gör att de boende får upp ögonen på ett alternativt sätt att leva. Slutsatsen är att institutionen bidrar till att förmedla känslan av att en förändring är möjlig. / ABSTRACT Title: ”It’s not supposed to be a bloody hangout where you bring people and stuff” A study on how homeless clients feels about living in communal group homes provided to them by the social services. The purpose of this paper has been to gain knowledge about homeless clients view on their housing situation. And also to learn more about how clients perceive the possibility to change and how they feel they are being treated at the social services collective housing facilities. A qualitative approach has been used in order to answer these questions. The empirical material consists of seven interviews with people currently staying at the communal homes mentioned above. The study’s frame of interpretation has consisted of theories and research about changing processes and strategies to counteract homelessness. Role theory has also been used in order to provide a deeper understanding of the interaction between individuals and between individual and organisation. The results in general show that it is hard to feel at home in an institutional setting. This has mainly to do with the unequal power structure that exists in such places. The study shows that under such circumstances oppressed people develop resistance strategies in order to cope. Furthermore the results points to the fact that resistance is more likely to occur when you’re feeling that you have no influence on your own future life situation. It is vital for the residents’ well being to be able to have an active part in their living situation. Those who feel they get adequate help in the institution are most likely to see the stay as a positive experience. The role of the staff is primarily limited to helping out with practical things. This can be seen as a way of helping the residents to adapt to society’s rules. Someone thinks that the staff also can function as a social support that helps them rethink their attitude towards their drug abuse. The results are somewhat ambiguous in that respect. The clients do want more of social support from the staff. At the same time they emphasises that the best agent in a successful changing process is the own self. The results finally show that the strict rules of the institution turn out to play an important role as a changing factor in the lives of the clients. The demand for total abstinence from drugs and alcohol helps in demonstrating for the clients an alternative way to live. The conclusion of this is that the institution contributes in conveying the message that change is in fact possible.

Preferential Flow Modelling in a Vadose Zone Using Macro 5.0 –Cape Flats Porous Sands.

Majola, Kwazikwakhe Alfred. January 2008 (has links)
<p><font face="Helvetica"> <p align="left">The objectives of this study were:&nbsp / To review and understand flow and transport processes in unsaturated zones. In this study, particular emphasis is placed on understanding mechanisms that cause non-uniform (preferential) flow for two casestudies, namely the Cape Flats sandy environment and the Mpumalanga Highveld fractured rock environment.&nbsp / To evaluate the adequacy of models, in particular MACRO 5.0, in simulating flow and transport in the vadose zone, by making use of two case study sites (Cape Flats and Mpumalanga Highveld). Of particular importance is the evaluation of transfer coefficients to represent fluid and solute exchange between macropores and matrix.&nbsp / To run a sensitivity analysis with MACRO 5.0 in order determine which input model parameters are the most relevant in describing the effects of preferential flow in water and solute transport.</p> </font></p>
