The complex interactions between individuals, institutions and information and communications technologies (ICTs) have generated a growing body of research that seeks greater knowledge of the processes at work and their consequences. Situated firmly within this area, this thesis challenges the dominance of the generalised and largely technologically deterministic narratives within the field by seeking to constitute such knowledge in a different way. Geography provides a useful standpoint from which to challenge these narratives owing to its enduring engagement with time and space, concepts implicit in any discussion of ICTs effects. Emerging work on code space, transurbanism and timespace are specifically used to negate the persistent dualistic treatment of time and space which is argued to be hampering geographic research in this field. Methodologically drawing from a non representational style this thesis uses these emerging understandings to access the in between, a mental space of performance; which involves the process of drawing from tacit knowledge, cognitive perceptions of the spatial and temporal environment and emotions, in order to explore the conditions of possibility that individuals are becoming aware of through their interactions with ICTs. Four empirical interventions are used to ground these emerging understandings into the reality of everyday encounters with ICTs in Auckland, New Zealand. The first focuses on the role of local government in the development of Auckland’s ICT infrastructure, a complex and contingent process. The second concentrates on the provision of a Real Time Passenger Information System at Auckland bus stops, exposing individuals to new timespaces while waiting for the bus. The third considers students opinions of the e-learning mechanisms used in two first year geography courses. The final intervention examines the role ICTs play in South Africans and South Koreans imagining, negotiation and mediation of the migration process to Auckland. In conclusion, this thesis contributes to how geography constitutes knowledge about ICTs at three different levels. Empirically, the four interventions contribute grounded findings to the debates in the geographic literature over interactions with ICTs. Methodologically, the conditions of possibility institutional and individual actors are beginning to perceive through their encounters with ICTs are revealed as are the timespaces that may eventuate from these. Theoretically, to understand how the interactions between individuals and ICTs are performed this thesis demonstrates the need to interrogate the in between as a process, not just a gap or blank.

Doctor of Philosophy (PhD) / This thesis presents a computational method for the inductive inference of explicit and implicit semantic design knowledge from the symbolic-mathematical syntax of design formulations using an unsupervised pattern recognition and extraction approach. Existing research shows that AI / machine learning based design computation approaches either require high levels of knowledge engineering or large training databases to acquire problem reformulation knowledge. The method presented in this thesis addresses these methodological limitations. The thesis develops, tests, and evaluates ways in which the method may be employed for design problem reformulation. The method is based on the linear algebra based factorization method Singular Value Decomposition (SVD), dimensionality reduction and similarity measurement through unsupervised clustering. The method calculates linear approximations of the associative patterns of symbol cooccurrences in a design problem representation to infer induced coupling strengths between variables, constraints and system components. Unsupervised clustering of these approximations is used to identify useful reformulations. These two components of the method automate a range of reformulation tasks that have traditionally required different solution algorithms. Example reformulation tasks that it performs include selection of linked design variables, parameters and constraints, design decomposition, modularity and integrative systems analysis, heuristically aiding design “case” identification, topology modeling and layout planning. The relationship between the syntax of design representation and the encoded semantic meaning is an open design theory research question. Based on the results of the method, the thesis presents a set of theoretical postulates on computable relationships between design syntax and semantics. The postulates relate the performance of the method with empirical findings and theoretical insights provided by cognitive neuroscience and cognitive science on how the human mind engages in symbol processing and the resulting capacities inherent in symbolic representational systems to encode “meaning”. The performance of the method suggests that semantic “meaning” is a higher order, global phenomenon that lies distributed in the design representation in explicit and implicit ways. A one-to-one local mapping between a design symbol and its meaning, a largely prevalent approach adopted by many AI and learning algorithms, may not be sufficient to capture and represent this meaning. By changing the theoretical standpoint on how a “symbol” is defined in design representations, it was possible to use a simple set of mathematical ideas to perform unsupervised inductive inference of knowledge in a knowledge-lean and training-lean manner, for a knowledge domain that traditionally relies on “giving” the system complex design domain and task knowledge for performing the same set of tasks.

O uso de substâncias químicas tem sido relatado em diferentes culturas e períodos históricos; entretanto os tipos de substâncias utilizadas, o contexto social, as práticas de consumo e o que é considerado excesso, bem como as práticas de seu controle e os modos de intervenção, apresentam especificidades. Deparamo-nos hoje com o fato de que o uso considerado abusivo pode ser caracterizado como doença (dependência). Para os sujeitos nessa condição de existência, existe toda uma estrutura de poderes (Ministério da Saúde e Ministério Público) e saberes (médico, jurídico, psicológico, religioso, etc.) propondo instituições e modelos de tratamento. Através da inserção em uma dessas instituições de tratamento para dependentes químicos e da análise dos modos de subjetivação e das políticas cognitivas, propomos uma pesquisa-intervenção, com a finalidade de possibilitar o exercício da cognição enativa/inventiva. Adotar como perspectiva a cognição enativa/inventiva implica estabelecer outra relação de conhecimento, baseada na produção de si próprio (autopoiese) e daquilo que tomamos por realidade em distintas redes de conversação. Dessa forma, as oficinas de máscaras surgem como uma proposta de pesquisa-intervenção que tem como objetivo mapear e acompanhar os movimentos cognitivos emergentes nas mesmas, inseridas no marco institucional de um serviço para dependentes de substâncias químicas. Tomamos como foco de estudo os modos pelos quais os usuários desse serviço de saúde que participam da oficina (intervenção) de produção de máscaras colocam questões e compartilham emoções - por eles consideradas pertinentes - em relação às experiências pessoal, institucional e com as tecnologias. Buscamos ainda, avaliar os efeitos da emergência de uma política de cognição enativa em um contexto terapêutico predominantemente recognitivo. Para a análise das oficinas, tomamos o conceito de cognição enativa como uma ferramenta metodológica que nos potencialize distinguir momentos em uma rede de produção-conversação nos quais exista um linguajar que vitalize coordenações de ações até então inusitadas na história desse coletivo e um emocionar no qual a experiência do outro possa ser aceita como legítima. / The use of chemical substances has been reported in different cultures and historical periods. However, the types of substances used, the social context, the consumption practices and what is considered excessive, as well as control practices and means of intervention present specificities. Nowadays, we face the fact that the use considered abusive may be characterized as a disease (dependence). There is a structure of powers (Health Ministry and Public Ministry) and knowledge (medical, legal, psychological, religious, etc.) proposing institutions and treatment models concerning subjects who live under such conditions. Through the insertion in one of such treatment institutions for chemical dependents and through the analysis of the subjectivation forms and of the cognitive policies, we propose an interventionresearch, aiming to enable the assignment of the inventive/enactive cognition. Adopting the inventive/enactive cognition as a perspective implies to establish another knowledge relation based on the production of oneself (autopoiesis) and on what we take as reality in distinct conversation networks. Thus, the mask workshops rise as a proposal of intervention-research that have as their aim to map and follow the cognitive movements emerging from them, inserted on the institutional placement of a service for chemical substance dependents. Our study focuses on the means by which the users of this health service that take part on the mask production workshop (intervention) lay questions and share emotions - considered relevant by them - concerning personal and institutional experiences, as well as the experiences regarding technologies. Yet, we pursue to evaluate the effects of the emergency of enactive cognition policies in a predominantly recognitive therapeutic context. Regarding the analysis of the workshops, we take the concept of enactive cognition as a methodological tool that potentializes the distinction of moments in a productionconversation network in which there is an expression through the language that vitalizes unusual coordination of actions in the history of this group and an emotional stimulation in which the experience of the other ones may be accepted as legitimate.

Interação homem-máquina, também difundida com o nome de Interface com o Usuário (ou simplesmente interface), é uma área de pesquisa relativamente recente e evidentemente multidisciplinar. Um importante critério para projeto de interfaces é a separação de um programa interativo em seu componente computacional (aplicação) e seu componente de diálogo (que implementa a interface) • Esta separação, denominada independência de diálogo, . cr1a o papel do projetista de interfaces separado do programador da aplicação e a necessidade de novas comunicações entre os componentes do programa e o usuário. O componente de diálogo é usualmente construído usando-se alguma Ferramenta para Desenvolvimento de Interfaces com o Usuário (abreviadas FIUs) para definição e manipulação de interfaces. As FIUs comercialmente disponíveis atualmente (na sua maioria "toolboxes" como MicroSoft Windows e Macintosh Toolbox, entre outras), no entanto, não são tão facilmente utilizáveis, contendo literalmente centenas de rotinas e confundindo freqüentemente os papéis do projetista de interfaces e do programador da aplicação. Isto acarreta prejuízos à almejada independência de diálogo .Além disto, devido às idiossincrasias de cada FIU, o p r ograma interativo é desenvolvido direcionado para o uso de uma FIU específica, necessitando de uma série de reformulações em caso de mudanças de FIU. O objetivo da dissertação é a proposta de uma FIU Canônica que permite: a) uma definição de interface de maneira mais adequada aos usuários projetistas, programador da aplicação; e mais notadamente ao b) a portabilidade de programas interativos entre diferentes FIUs. O componente principal da FIU Canônica é o seu modelo representacional orientado a objetos, o Canonicus, que contém as abstrações necessárias para o uso adequado dos usuários projetistas. A portabilidade vem do fato da FIU Canônica ser, na verdade, uma camada intermediária entre a aplicação e uma FIU. Sua implementação consiste na tradução de seus objetos e operações para objetos e operações de alguma FIU subjacente. Nesta dissertação sao apresentados a arquitetura da FIU Canônica e o seu modelo representacional Canonicus assim como a sua implementação sobre duas FIUs tipo "toolbox" comerciais, o MicroSoft Windows e o Macintosh Toolbox. / Human-computer interactionf interface f lS a mul tidisciplinary and research issue. also named use r relatively recent An important criteria to user interface design is the separation of interactive program in two components: computational component (application) and dialogue component (which implements the user interface).
