Missing Resource - Piecing Together Pretoria's Creative Future
No full textMini Dissertation (MArch (Prof))--University of Pretoria, 2019.An alternative school is an educational setting designed to accommodate educational, behavioral, and/or medical needs of children and adolescents that cannot be adequately addressed in a traditional school environment (Health 2010).
Many educational facilities fail to cater for the needs of learners that are less conventionally academic and more creatively inclined, by not providing resource facilities that allow for use and growth within them. The Pretoria inner city schools are a good example of this and thus students do not experience perceptive growth in the same manner that students in schools with these resources do. This gap needs to be filled by means of a communal resource sharing facility that allows for use by many different parties through investigation of global and South African educational theories and overlapping building typologies from each to find the specific gaps required to have a successful outcome This allows for equality of opportunity, which is essential in a country like South Africa and allows for people to have the ability to dictate their own futures through cognitive and perceptive growth as well as being essential to wellness of mind. The result of the investigation leads to a small step in the correction of the missing resource in order to improve cognitive and perceptive wellbeing.ArchitectureMArch (Prof)Unrestricte

Host-endophyte-pest interactions of endophytic Fusarium oxysporum antagonistic to Radopholus similis <i/>in banana (Musa spp.)
No full textThesis (PhD (Plant Pathology))--University of Pretoria, 2006.Radopholus similis is one of the key pests of banana in the East African Highlands and in the world. Although control of this pest has mainly relied on the use of clean planting material, re-infestation of plants in the field remains a critical concern. Alternative management options such as the use of fungal endophytes may be used to provide protection and extend plant life. In this study, a total of 35 endophytic Fusarium isolates were screened for the production of secondary metabolites antagonistic to R. similis in culture. Undiluted and diluted culture filtrates were tested against motile stages of R. similis and eggs. Tests were conducted using culture filtrates of the fungal isolates grown in banana corm broth. All isolates tested demonstrated some level of in vitro antagonistic activity on the mobility of R. similis mixed stages (males, females and juveniles). The percentage of immobilized nematodes increased with increase in the length of exposure time to culture filtrates. After 24 hrs exposure, up to 100% of nematodes were immobilized compared to 26.5% in control treatments. Mortality of mixed stages of R. similis exposed to culture filtrates for 24 hrs, followed by rinsing with sterile distilled water, demonstrated that the effects of culture filtrate treatment were irreversible, as nematodes did not recover and were considered dead. Nematode mortality rates after 24-hr exposure periods ranged from 76.4% to 100.0%. The effects of culture filtrates on R. similis motile stages increased with increasing culture filtrate concentration. Culture filtrates also demonstrated inhibitory effects on hatching of R. similis eggs. Radopholus similis males were more sensitive to culture filtrate treatment than females. The results obtained demonstrate the potential for using endophytic Fusarium isolates as biological control agents against R. similis and/or toxic derivatives as potential nematicides against the nematode.Microbiology and Plant Pathologyunrestricte

The application of artificial mussels in conjunction with transplanted bivalves to assess elemental exposure in a platinum mining area
No full textThere is increasing evidence that platinum group elements (PGE) are pollutants of emerging
concern worldwide. Limited information exists on levels, particularly in regions where PGEs are
mined. A passive sampling device (i.e., the artificial mussel (AM)) and transplanted indicator
organisms (i.e., the freshwater clam Corbicula fluminalis africana) were deployed along a PGE mining
gradient in the Hex River, South Africa, and concentrations of As, Cd, Co, Cr, Ni, Pb, Pt, V, and Zn
were determined after six weeks of exposure. Results showed differential uptake patterns for Pt, Cr,
and Ni between the AMs and clams indicating availability differences. For monitoring purposes,
a combination of AMs and indicator organisms provides a more holistic assessment of element
exposure in aquatic environment
Ciò che resta della terza dimensione
No full textThe s.c. «third dimension» is one of the first definitions given in the sociological arena to define the development of a ate element that was not identifiable with generalist instances of the state or with those particularistic of the market. Deriving its conceptualization from the Husserlian theory, Ardigò through the use this approach emphasizing the need to reconstruct the crisis through new forms of transaction between the social system and life-worlds. The use of this conceptualization led to the identification of these intermediary organizations between different systems. The text takes a brief overview of the third dimension organizations and the way how they operate the reconciliation between inter-subjectivity and super-ordination present in the systemic sense. It is proposed a scheme of interpretation, drawn from the author in question, through which classifying not merely the organization but the possible interconnections between micro and macro and their consequences. It is concluded that the abandon of the analytical perspective proposed by Ardigò, primarily for the affirmation of a vision of an economic nature, was determined both by the theoretical vulgate established around of the 90, and the difficulty in operationalizing a definition that owed much to the knowledge from the phenomenology of the Bolognese scientist
Alla ricerca della sovranità nello studio di Carlo Lavagna sulle figure giuridiche soggettive
No full textIl presente contributo ripercorre il saggio di Carlo Lavagna, Basi per uno studio delle figure giuridiche soggettive contenute nella Costituzione italiana, allo scopo di ricercare il filo conduttore della sovranità in tutte le figure giuridiche soggettive sia che esse siano solo raccomandate, sia che siano garantite o anche tutelate dalla Costituzione, secondo la classificazione dell’Autore. Tale analisi è stata preceduta da un breve richiamo al metodo di indagine dell’Autore e alla sua concezione quadrangolare della democrazia.This contribution reinterprets the essay by Carlo Lavagna, Basis for a study of the subjective juridical figures contained in the Italian Constitution, in order to search for the sphere of sovereignty in all subjective legal figures whether they are only recommended, whether they are guaranteed or also protected by the Constitution, according to the classification of the Author. This analysis was preceded by a brief recall of the Author's method of investigation and its quadrangular concept of democracy
The Understood Author: A hermeneutical exploration of audiences interpretation of the author as productive practices behind a text
No full textin English This project builds on the tradition of audience research that theoretically and empirically established that meaning is formed in the negotiation between the text and the reader, that the audiences are agentic, their interpretation of media is contextual and situated, and that they have the potential to resist the media. It argues that it is important to explore people's attention to different sources: who is listening, to whom, and why - and asks how people understand the notion of an author that they encounter in the interpretation of factual media texts, and how this interpretation is brought back into the interpretative act. The thesis subscribes to philosophical hermeneutics as an overarching theoretical as well as methodological framework to devise a concept of an understood author that is a result of the interpretative act, where the author imagined and anticipated by the reader (in the form of prior knowledge and prejudices) is encountered and actualised by the author inscribed into the text. I carried out 28 in-depth face-to-face interviews with Czechs born between 1948-1963 to explore participants' experiences and relationship with media and media authors. Employing hermeneutical analysis, the focus is not to capture what is an author, but how it happened to be so. The..
