Thesis (MTech (Design))--Cape Peninsula University of Technology, 2008 / This thesis argues that the story of hemp is one of mistaken identity and focuses on the potential of hemp (Cannabis sativa L.) in a social and economic context. It also asserts how hemp with the application of appropriate technologies can be developed nationally 'new' material, with reference to examples from abroad. The current proliferation of raw material shortages means that designers have a social responsibility to seek new ways to source and process materials for a sustainable future. Designers are the "future creators" and should prescribe materials that are not only healthy in the cycle of production, but also ensure an afterlife (recycling). The methodology employed is a combination of qualitative (such as interviews) and quantitative methods (such as statistical analysis). Life Cycle Analysis is used to study the ecological impact of substituting hemp for current materials and processes. The study interrogates the historic significance of hemp in various societies across the world with particular focus on Europe, Japan, the United States of America, Ireland and Australia. Such information is analysed within the realities of the South African context. A vast amount of information on hemp has been published but practical information is hard to obtain in South Africa necessitating a search for definite answers abroad, mainly in Europe where there is a strong development in this field. After researching the production of the hemp raw materials and the manufacture of viable hemp products abroad, lessons could be assessed for application to the local market. The findings endorse the view that hemp is a sustainable zero-waste material; the whole plant can be used when harvested, which makes it an ideal material on which to base an eco-design system. Hemp can be processed by utilizing either high technology equipment or by the use of locally available equipment and manual labour. It can be converted into a multi-diverse range of viable products such as paper, thatching, building material and ceiling panels. The main reason for the isolation of hemp in South Africa is the mistaken assumption that it is a drug and outlawed by our legislation. Since hemp (Cannabis sativa L) is perceived as a vilified cousin of marihuana it has lead to a blanket ban on both plants. This is certainly not warranted as hemp produces an extremely low value of the controversial hallucinogenic tetrahydrocannabinol (THC)properties which is negligible.

Growing recognition of the profound topics affecting society; including population changes, social issues, and environmental crisis; is emphasising the need for industrial designers to address additional goals beyond those associated with purely commercial targets. Industrial design consultants, however, have a myriad of complex and inter-related elements influencing their work. This thesis investigates those influences and offers a portrayal of what affects industrial design consultants addressing more responsible design goals within their commercial remits. It reviews the literature relating to the nature and role of industrial design, and its relationship with society s larger needs. From this, it expounds the methodology underpinning the investigation, and describes the phases involved. Two main studies were undertaken to pursue the research objectives: an explorative workshop involving 19 participants from design practice and academia; and a series of semi-structured in-depth interviews involving a total of 31 industrial design consultants, leading academics, and design-related strategic consultants. From the analysis of the data, three sets of key observations and theory are presented in the thesis. The first set of findings examines the range of influencing factors acting on the consultant and their work by depicting the characteristics of the main elements constructing the product creation context. The second and principal set of findings identifies what determines the possibility for consultants to incorporate responsible design goals within their work. Using a framework derived from the analysis, and drawing on interview data for empirical backing, it expands on six key areas, identifying a critical determining factor for each. The third set of outcomes combines the findings from the primary data with existing knowledge on design actions and behavioural theory, to depict the formation of an industrial design consultant s behaviour and their tendencies towards responsible design. In this way, the research offers a thorough investigation of what affects industrial design consultants addressing more responsible design goals, by considering the characteristics of their circumstances; the determination of their possibility to act; and what shapes their individual behaviour.

Thesis (MTech (Design))--Cape Peninsula University of Technology, 2011 / This study explores the possibilities of using design interventions in mitigating crime. The study employs the Design Against Crime (DAC) philosophy in dealing with crime, which provides a holistic perspective regarding crimeand related issues.High crime levels in South Africa necessitate alternative approaches to dealing with crime, as it is becoming evident that the old strategies that have been utilised are not providing the desired effects.The focus is on the emergence of crime amongst youth at risk, living in communities-in-tension and more specifically,the Bridgetown community near Cape Town. Communities which constitute the lower socio-economic income level, usually suffer the most with regards to crime. The effects of crime negatively influence the development of the community, allowing the cycle of poverty and crime to continue. If the cycle of crime can be broken in these communities, development may take place which will strengthen them in a number of ways, including their standing in society. In order to gain a better understanding of the crime situation in South Africa, the study investigates the country‘s crime history and its widespread effects on society today. The research also looks at other factors such as personal and environmental settings that inform an individual‘s decision to commit crime. Delinquency and its results are also explored. The theoretical lens used in the study is that of Socially Responsible Design (SRD), with DAC as a subsection.SRDlooks at providing solutions to societal problems from a holistic point of view. The study uses a qualitative approach which focuses on people in real life situations,allowing the researcher to gain insight into what motivates people in their specific circumstances. The participants involved in the study are members of the Bridgetown community, youth from that community and theReconstructed Living Labs (RLabs) team, who were previously involved in crime. The researcher sought the views of experts in the field with regards to crime alleviation in communities such as Bridgetown. This research study concludes that opportunities exist forholistic and multi-faceted deployment of DAC strategies in that community to ameliorate crime, when these strategies targetyouth at risk.

[pt] Esta dissertação apresenta o Template de Metacomunicação Estendido, uma ferramenta, denominada Template Estendido de Metacomunicação, baseada em um conjunto de perguntas-guia derivadas da teoria da Engenharia Semiótica. Relatamos os resultados de um estudo para avaliar seus impactos no processo de design de sistemas de aprendizagem de máquina. Ao solicitar que designers e desenvolvedores respondam um conjunto de perguntas, a ferramenta busca auxiliá-los a organizar mentalmente suas interpretações da solução de design, ao mesmo tempo que revisitam as pressuposições por trás dela. Descrevemos, então, um estudo de design especulativo e analisamos seus resultados, identificando temas emergentes que nos ajudam a entender como a ferramenta proposta pode ser utilizada. Dentre os aspectos identificados mais relevantes estão a prática reflexiva do design, a atenção ao uso de linguagem, a atribuição de responsabilidade às pessoas envolvidas, o uso do arcabouço ético de apoio fornecido, os princípios da bioética, e as possíveis formas de se usar o template estendido. / [en] This dissertation presents the Extended Metacommunication Template, a tool based on a set of guiding questions derived from the theory of Semiotic Engineering. We report the results of a study we conducted to evaluate the tool s impacts on the design process of machine learning systems. By having designers and developers answer a set of questions, the tool aims to help them reflect on their interpretations of the design solution, while allowing them to revisit the presuppositions behind it. We then describe a speculative design study and analyze its results, identifying emergent themes that help us understand how the proposed tool may be used. Among the relevant themes identified are: the reflective practice of design, the designer s focus on their use of language, the process of attributing responsibility to the people involved, the use of the ethical framework provided to them, the bioethical principles, and the ways in which the extension of the template may be used.
