Esta tese de doutorado apresenta um estudo e formulações teóricas sobre o conceito de espect-autoria e defende os conceitos de Poética da Autoria Aberta, Poética da Autoração e Poéticas em Coletividade como praxis artística de apropriação dos dispositivos de produção das representações sociais, no contexto da autoria dos espectadores nas artes participativas e interativas. Numa transferência interdisciplinar de conceitos a exemplo do conceito espect-autor de Gellouz (2007), o estudo propõe as noções de autorabilidade, obra autorável, agenciamento autoral do espectador e trinômio produção/recepção/produção bem como os conceitos formulados de função-espect-autor, espect-autor em coletividade, particip-autor, inter-autor e trans-autor, que privilegiam a noção de autoria em suas notações, configurando uma taxonomia mais apropriada para compor um vocabulário que permita designar e compreender a noção de espect-autoria, ou seja, a produção autoral dos espectadores, enquanto forma, repertório e significados, nas obras cuja abertura poética propõe desafios autorais aos seus espectadores. A principal referência artística e fonte desta pesquisa é a série Autorretrato Coletivo (1987-), um conjunto de obras participativas e interativas que eu proponho como repositório dialógico e polifônico da identidade coletiva, tendo como princípio a apropriação dos espectadores enquanto autores de suas identidades no corpus da obra. Em suma, a função-autor exercida pelos espectadores, mais precisamente a sua função-espect-autor, em processos de criação/co-criação ou recriação (por recombinação e/ou repertoriação) no contexto das artes participativas e interativas, tem profundas implicações para nossa compreensão da evolução da arte como um fenômeno coletivo. / This thesis presents a study and theoretical formulations about the concept of spect-authorship on participatory and interactive artworks and defends the concepts of Poetics of the Open Authorship, Authoring Poetics and Multi-Poetics in Collectivity as artistic praxis of apropriation of the production devices of the social representations in the context of the spectators authorship in the participatory and interactive arts. Through an interdisciplinary transfer of concepts as Gellouz concept of spect-author (2007) , this study proposes the notions of authorability, authoriable artwork, authorial agency of the spectator, trinomial production/reception/production as well the concepts of function-espect-author, spect-author in collectivity, particip-author, inter-author and trans-author, which privilege the notion of authorship, setting a taxonomy more appropriate to compose a vocabulary that describes and increases the understanding of the concept of spect-authorship, the authorial production of the spectators as form, repertory and meanings, in the artworks whose poetic openness proposes authorial challenges to their spectators. The main artistic reference and source of this research is the series Collective Self-Portrait (1987-), a set of participatory and interactive artworks that I propose as a dialogic and polyphonic repository of the collective identity, based on the principle of appropriation of the spectators as authors of their own identities in the corpus of the artwork. Summing up, the author-function experienced by the spectators, more precisely their spect-author-function, in creation/co-creation or recreation process in the context of participatory and interactive arts, holds profound implications for our understanding of art evolution as a collective phenomenon.

>Magister Scientiae - MSc / The Kuils River Catchment is an urban river catchment that forms part of the larger Kuils-Eerste River system draining the eastern half of the Cape Metropolitan Authority area and Stellenbosch Municipality. Rapid urbanisation has resulted in the encroachment of residential and industrial areas into the river system through channelization and sewage disposal. This research project intends to assess the quality of surface runoff in the Kuils River catchment and determining non-point source pollutant loading rates in the catchment using GIS-based modelling. The study results show how modelled potential sources of surface runoff and NPS pollutants using desktop GIS analysis tools in a sequential process that involved different levels of software applications could explain the characteristics of the catchment. With the help of the Expected Mean Concentration (EMC) values associated with surface runoff from land use/covers, NPS pollutant loads were assessed downstream towards the Kuils River Catchment outlet using the Nonpoint Source Pollution and Erosion Comparison Tool (N-SPECT) based in ArcGIS. The outputs from this model consist of predicted annual pollutant loading (mg/mvyear) for each Kuils-Eerste River that occurs in the catchment. The results have shown clearly the spatial distribution of sources of particular pollutants in the catchment. Further or advanced processing knowhow with this model might provide far reaching insights into the problem and it is however recommended that these results produced using N-SPECT be compared to those of other hydrologic models using the same inputs.
