Design fixation is a phenomenon experienced by professional designers and engineering design students that stifles creativity and innovation through discouraging ideational productivity, fluency and diversity. During the design idea and concept generation phase of the design process, a reliance on perceptual surface feature similarities between design artefacts increases the likelihood of design fixation leading to design duplication. Psychologists, educators and designers have become increasingly interested in creative idea generation processes that encourage innovation and entrepreneurial outcomes. However, there is a notable lack of collaborative research between psychology, education and engineering design particularly on inductive reasoning of undergraduate engineering students in higher education. The data gathered and analysed for this study provides an insight into property inference decision-making preferences and decision switching (SWITCH) patterns of engineering undergraduates under similarity-based inductive judgements [SIM] and category-based inductive judgements [CAT]. For this psychology experiment, property induction tasks were devised using abstract shapes in a triad configuration. Participants (N = 180), on an undergraduate engineering programme in London, observed a triad of shapes with a target shape more similar-looking to one of two given shapes. Factors manipulated for this experiment included category alignment, category group, property type and target shape. Despite the cognitive development and maturation stage of undergraduate engineers (adults) in higher education, this study identified similarity-based inductive judgements [SIM] to play a significant role during inductive reasoning relative to the strength of category-based inductive judgements [CAT]. In addition to revealing the property inference decision-making preferences of a sample of undergraduate engineers (N = 180), two types of switch classification and two types of non-switch classification (SWITCH) were found and named SIM_NCC, SIM-Salient, Reverse_CAT and CAT_Switching. These different classifications for property inference switching and non-switching presented a more complex pattern of decision-making driven by the relative strength between similarity-based inductive judgements [SIM] and category-based inductive judgements [CAT]. The conditions that encouraged CAT_Switching is of particular interest to design because it corresponds to inference decision switching that affirms the sharing of properties between dissimilar-looking shapes designated as category members, i.e., in a conflicting category alignment condition (CoC). For CAT_Switching, this study found a significant interaction between a particular set of conditions that significantly increased the likelihood of property inference decisions switching to affirm the sharing of properties between dissimilar-looking shapes. Stimuli conditions that combined a conflicting category alignment condition (where dissimilar-looking shapes belong to the same category) with category specificity, a causal property and a target shape with merged (or blended) perceptual surface features significantly increased the likelihood of a property inference decision switching. CAT_Switching has important implications for greater ideational productivity, fluency and diversity to discourage design fixation within the conceptual design space. CAT_Switching conditions could encourage more creative design transformations with alternative design functions through inductive inferences that generalise between dissimilar artefact designs. The findings from this study led to proposing a Cartesian view of the concept design space to represent the possibilities for greater movements through flexible and expanding category boundaries to encourage conceptual combinations, greater ideational fluency and greater ideational diversity within a configuration design space. This study has also created a platform for further research into property inference decision-making, ideational diversity and category boundary flexibility under stimuli conditions that encourage designers and design students to make inductive generalisations between dissimilar domains of knowledge through a greater emphasis on causal relations and semantic networks.

Introduction Colour codes are used extensively in railways to convey specific information governing movement of trains and equipment on the track. One such task is the railway traffic control display that uses colour coded video display terminals (VDTs) to convey information of the signal status, train movements and track status to the railway dispatcher. Because individuals with colour vision deficiencies (colour-defectives) may have problems with these colour-related tasks, questions were raised about the suitability of colour vision defectives to work as railway dispatchers. In order to answer that, a VDT based Dispatch Colour Vision Test based on the actual railway traffic display was developed previously. Purpose The main purpose of this thesis is to establish the pass/fail scores and repeatability of the VDT based Dispatch Colour Vision Test that resulted from the previous work. Secondly, the study will also examine whether clinical colour vision tests can predict the performance on the practical task. Methods The Dispatch colour vision test was divided into three parts based on the colour sets that the dispatcher had to recognize. The testing computer system used the the same RGB colour settings, graphics card and monitor as in railway dispatch centres. Subjects viewed the display colours and entered their responses by using a mouse. One hundred colour-normals and fifty two colour-defectives participated in the initial session. The test was repeated approximately after 10 days. Ninety three colour-normals (93%) and 44 (85%) colour-defectives participated in the second session. The total number of errors and time to complete the test was recorded. Results Pass/Fail on the VDT Dispatch colour vision test was based on colour-normal errors. Ignoring orange-red errors, two errors were allowed in the first session and one error was allowed in the second session. Based on this criterion, 42% of colour vision defectives could perform as well as colour normal subjects. The kappa coefficient of agreement between the sessions for the colour-defectives was 0.85. Detailed analysis between the colour differences and the errors showed only a weak correlation between the two. However, the general trend was that colour-defectives made more errors on colours that were near or along the same lines of confusions and the colours were nearly equal in luminance. Nevertheless, the interaction between luminance and location with respect to the lines of confusion was not easy to interpret. The time to complete the task for the colour-defectives who passed the test took 14% longer than colour-normals and colour-defectives who failed took 30% longer than colour-normals. All groups showed a similar learning effect with an 18% reduction in mean times to complete the task at the second session. There was no significant correlation between the number of errors and time to complete or the clinical tests and completion times for any of the groups. Clinical colour vision tests have limited value in predicting performance of colour-defectives on the Dispatch test. Logistic analysis results showed that the Farnsworth D-15 along with the Nagel was the best predictor of the VDT Dispatch colour test pass/fail results. However, these results were similar to using the Farnsworth D-15 test alone. Ninety-five percent of the individuals who failed the Farnsworth D-15 also failed the Dispatch test. However, approximately 25% of the individuals who passed the Farnsworth D-15 failed the VDT Dispatch colour test which is an unacceptable false negative rate. These results indicate the Farnsworth D-15 can only be used to predict who is likely to fail the dispatch test. Conclusions Forty two percent of colour vision defectives could perform as well as colour-normals in identifying VDT railway display colours and time to complete the task. Clinical colour vision tests were inadequate predictors of performance in practical task, overall. However, the Farnsworth D-15 was a very good predictor of who would fail the VDT Dispatch test. Hence a practical VDT Dispatch test may be needed to test individuals who would want to work as railway dispatchers.

The aim of this study is to discover how primary scholars as substitute parents, contemplate the perceiving aspect of their substitute parenting. In the theoretical chapters the demands set for adults as primary educators and their development, are viewed. A comparative study between the primary edu­ cator and the child, rounds it off. The experiencing, giving meaning to, and the consequent involvement of substitute parents in their life-world, follow. The research design, substantiates the choice of format, methods of data col­ lection and analyses. Examples of raw data gathered from various tests are presented. Finally, the consolidated data is interpreted. The findings of this study is that substitute parents experience their tasks as being pleasant. Substitute parents are generally over involved with their siblings. This culminates in the development of a strong bond between substitute parents and younger siblings. Substitute parents require support and guidance from an adult to enable them to become adults and venture in their life-world. / In bierdie studie is die leefWereld van die substituut-ouer bestudeer. Die oorhoofse doel van hierdie studie is om met behulp van teoretiese en empiriese studies, ondersoek in te stel na substituut-ouers se belewing van bulle besondere taak. Die studie neem 'n amwang met 'n beskrywing van die primere opvoeder se verantwoordelikhede en eise. Die ontwikkeling van die volwassene word daama bestudeer. Verder Is gelet op die e1se en ontwikkeling wat aan kindwecs gelykgestel word. Die doel hiermee, is om uiteindelik 'n vergelyking te kan tref tussen die volwassene en die kind. Nadat so 'n vergclyking tussen die kind en volwassene gemaak is, sal die probleme wat die kind as substituut-ouer ervaar, oorweeg kan word. Die literatuurstudie kulmincer in substituut-ouers se unieke betekenisgewing, betrokkenheid en belewing aan en by bulle leefWereld. Dan word die literatuurstudie opgevolg deur die navorsingsontwerp, keuse van steekproef­ neming asook wyses van dataverameling en -analisering. Ten slotte word daar gekyk na die verslaggewing aangaande inligting soos bekom met behulp van die verkenningsmedia, te wete individuele onderhoude met die deelnemers aan die navorsing, die Bene-Anthony gesinsverhou­ dingstoets, die Persoonlikheidsvraelys vir kinders, die projeksiemedia van Jacobs en Vrey en die Kinestetiese huisgesinstekeninge. Die gekonsolideerde data word dan geinterpreteer en weergegee ten einde die postulate soos in boofstuk 5 uiteengesit te beantwoord. Die belangrikste bevindings van die studie is dat die taak van substituut­ ouerswees vir laerskoolkinders aangenaam is. Hierdie aangename belewing van hulle taak as substituut-ouers, dra egter nie by tot die vonning van 'n positiewe selfkonsep by die substituut-ouer nie. Substituut-ouers ervaar angs en kommer aangaande hulle substituut-ouerskap. Hulle voel nie bevoeg om as substituut-ouers op te tree nie. Substituut-ouers IS oar die algemeen oorbetrokke by hulle broers en susters. Hulle sien om na hulle sibbe, verseker dat hulle veilig is en verleen hulp aan hulle, waar nodig. Hierdie betrokkenheid veroorsaak 'n sterk band tussen die leerlinge. Hierdie sterk band wat tussen die substituut-ouers en hulle sibbe bestaan, is egter afwesig tussen die substituut-ouers en hulle eie ouers. Substituut-ouers toon dan oak teen die verwagting van die navorser in, dat hulle nie beskik oor 'n verantwoordelikheidsin nie. Substituut-ouers k:an eerder beskryf word as teruggetrokke, met min deursettingsvennoe, prikkelbaar, goedhartig, onderdanig, athanklik en inskiklik. Die studie toon ten slotte dat substituut-ouers betrokke raak by hulle taak as substituut-ouers, vanwee 'n aansporingsmiddel, te wete sakgeld. Benewens vir die bogenoemde bevindings, toon die studie oak dat die ondersteuning en begeleiding van substituut-ouers deur 'n volwassene tot volwassenheid noodsaaklik is. / Psychology of Education / M.

This project deals with given safeguard possibilities, both mechanical and electronic. A row house with garden was chosen for being secured. Subsequently, were elaborated two`s proposals of securing and guarding of this object. First, was based on camera`s system and second on common system ESS. Later on they were evaluated and the most considerable benefits were emphasized. A system based on control panel with connected detectors was selected upon specification. Subsequently was created a model of the chosen system, at which the required behaviour was simulated and verified. An outline of an implementation was created in the C language.

Recent studies have shown that there may be evidence that children with reading difficulties have particular compensatory spatial ability, although the exact spatial ability has not been identified. This study used qualitative and quantitative methods to examine closely two spatial abilities, spatial visualisation (mental rotation from memory) and visual realism (three-dimensional drawing and construction ability) in students with reading problems and students with no problems. The aim was also to explore the question of whether students with spatial ability and reading problems were encouraged to use these strengths either in or out of school and whether such abilities could be identified in the early years environment. Equally, the question of motivational failure related to possible unrecognised potential, particularly in the area of non-verbal/spatial ability was also examined. This study used longitudinal case studies with five children and their mothers over a period of ten years. Interviews were transcribed and analysed using a grounded theory approach. Researcher observations as the teacher of the five children in their primary years provided additional evidence of their reading and spatial abilities at an early age. In addition, the study uses a Further Education College survey that examines spatial ability and reading problems in 133 post-16 year olds that provides the quantitative element of the study providing evidence about students with spatial abilities and their career choices. The data analysis revealed that the five case studies had largely overcome their reading problems due to early intervention strategies for reading together with encouragement and support outside school for their spatial abilities. Additionally, they have pursued careers, which for the most part, uses their spatial skills. The data analysis of the College survey showed that the link between spatial ability and reading problems was less secure, although there were a number of students with Specific Learning Difficulties (SpLD) who had high spatial abilities and this proved to be important from the point of view of identifying strengths alongside weakness in literacy, particularly in the early years at school. Early identification and acknowledgement of spatial ability as a perceived strength and used to support learning, as opposed to identification of reading problems, a perceived deficit, proved to be a key finding of the research.

No. of bitstreams: 0 Previous issue date: 2009 / Este trabalho propõe analisar o fenômeno da terceirização desenvolvido ao longo das duas últimas décadas em Bio-Manguinhos. Trata-se de um estudo de caso realizado na unidade de produção de vacinas e reagentes para diagnóstico da Fundação Oswaldo Cruz. Inicialmente foi realizado um estudo de cenário, analisando a política de gestão do trabalho desenvolvida pelo Estado brasileiro para as instituições públicas. A seguir, a análise passou a verificar a inserção da Fiocruz nessas políticas, desde a sua criação e no decorrer de vigência de diferentes formas de contratação, alternando da extrema rigidez para a total flexibilidade sempre com foco na gestão do trabalho, e, como essas políticas se refletiram no desempenho de Bio-Manguinhos. Baseado no contexto da conformação do Estado e na análise do desempenho da unidade, o trabalho critica a falta de planejamento e de prospecção dessas políticas, que favoreça a inovação de processos, produtos e procedimentos e o desempenho pleno de uma unidade de produção de insumos para a saúde, tão necessários ao atendimento das necessidades da população brasileira. Critica também, a ausência de um modelo de Estado consolidado que sirva de arcabouço à formulação dessas políticas. Devido às fortes críticas dos órgãos de controle acerca da extrapolação dos limites da terceirização praticada nas últimas duas décadas e à falta de definição clara desses marcos legais, o trabalho apresenta uma metodologia baseada nas atribuições dos cargos do plano de carreiras da Fiocruz e culmina com a apresentação de uma matriz de atribuições passíveis de serem realizadas por contratação indireta. Conclui pela necessidade de convivência de dois quadros de trabalhadores: um permanente formado por servidores, estáveis e de carreira e outro flexível, executado por contratação indireta, de caráter eventual, temporário ou de apoio às atividades relacionadas à missão de Bio-Manguinhos. O trabalho ainda sugere a aplicação da mesma metodologia às demais unidades da Fiocruz e que a instituição afirme, frente aos órgãos de controle, quais atividades que ela precisa manter no quadro de servidores permanente e quais ela quer delegar a terceiros sem contudo, ferir a legislação vigente. Por fim, constata-se que a metodologia apresentada ameniza, mas não resolve o problema, dessa forma, recomenda-se à Fiocruz buscar mecanismos que altere o modelo de gestão pelo qual está submetida a fim de viabilizar as duas formas de incorporação de mão-de-obra.
