The intention of tailorable systems is to make it possible for end users to evolve an application to better fit altered requirements and tasks, and to make the system more endurable. This thesis discusses tailorable systems in the context of a rapidly changing business environment. The objective was to determine what is necessary for a tailorable business system to continuously adapt to expanding requirements and thereby live up to the intention of the system. The thesis includes five different studies, of which one is a literature study. The other four studies were conducted in three projects; one technical project exploring the possibility to use Metaobject Protocol in tailorable systems, one project in an explorative environment concerned with physical interfaces and one project, that also embraced user participation and user evaluation, regarded the possibility for end users to manage system infrastructure. The projects began with field studies (including participant observations and interviews) and workshops with users and developers. In each project, based on the outcome, an end-user tailorable prototype was developed. The prototypes were used for evaluating possibilities and problems with tailorable systems. Taken together the evaluations revealed what was required to make a tailorable system work as intended in a rapidly changing business environment. It could be concluded that tailoring is a good way to evolve a system to meet altered needs, because people who already possess the required domain knowledge can make changes quickly. Tailoring is not however enough, because the tailoring capabilities are always limited, meaning that tailoring cannot support completely unanticipated changes. In such cases the tailoring capabilities must be extended. Since such changes are only concerned with the system itself, and not the business task, it is hard to motivate even skilled users to make these types of changes. Tailoring activities must therefore be coordinated with software evolution activities performed by professional developers. This allows the system to adapt continuously to a rapidly changing business environment and thereby live up to the intention of the system. The final conclusion is that there is a need for close collaboration between end users, tailors and developers to make tailorable information systems adaptable to rapid changes in the business environment as well as being endurable. The collaboration has to be supported in the structure of the system by providing support for the work of users, tailors and developers.

Abstract This thesis contributes to the field of collaborative information systems and Computer-Supported Cooperative Work (CSCW). It extends the notion of technological support for design activities "in use" beyond providing the flexibility to tailor collaborative software, to provide means to support the appropriation process of these tools in their application fields. Two long-term studies on the evolution of usages of collaborative software in a German authority and in a network of freelancers in the field of consulting form the foundation of this work. Based on the experience there, it was possible to identify user activities that drive the appropriation process and to establish a perspective on the appropriation of a Groupware as a social process. Appropriation can be described as a collaborative effort of end users, who perform "appropriation activities" to make sense of the software in their work context. Besides activities to configure the software to fit into the technological, organisational and individual work context of the users ('Tailoring'), there is a larger area of technology-related communication, demonstration and negotiation activities aimed at establishing a shared understanding of how a software artefact works and what it can contribute to the shared work context. The mutual shaping of the technology and organisational contexts resemble an ongoing design process that end users perform largely without any involvement of professional developers. This perspective is the guiding line for developing means for "Appropriation Support", i.e., means to support the appropriation activities that end users perform. To inform the design of appropriation support measures and functions, current approaches that capture the collaborative dimensions of tailoring, and the necessities of 'discourse ergonomics' for technology-related online communication are explored. The trend to work with a tool 'infrastructure' instead of monolithic Groupware tools is a complicating yet important secondary consideration here, since it demonstrates the necessity to offer support 'beyond one tool' to support a use-oriented perspective on appropriation. The resulting idea of 'Use Discourse Environments' as a main concept for appropriation support which captures the activities of communication, demonstration and negotiation as well as the activity of tailoring (where possible) was implemented and evaluated in two prototypes that refer to the application fields of the initial studies. The idea of integrating online discourse, tool representations and tailoring facilities served as a guideline for the use discourse both in an event notification service as well as in the 'Online Future Workshop' that addressed a shared inter-organisational software development infrastructure. Based on the evaluations, design recommendations for appropriation support are made, and the problematic nature of appropriation activities as 'infrastructural work' versus the 'productive work' that end users consider their main area of work is addressed. The thesis concludes with a vision of collaborative software tools that do not only provide their original services, but also address end users as a 'virtual community of technology practice'.

Doctor of Philosophy / Department of Psychology / Laura A. Brannon / Two studies address the serious problem of college student binge drinking. Both studies identify factors that improve the effectiveness of public service announcements (PSAs) encouraging responsible drinking presented through a website simulation. Study 1 tested four levels of Message Personalization (i.e., extent to which the PSA targets important aspects of the individual's personality) by comparing the effectiveness of messages matched to the person's Big Five personality traits, their actual self-schema, their ideal self-schema, or a non-personalized control message. Matching to actual self-schema has been found to be effective in past research. However, it was expected that the more thoroughly personalized the message, the more effective it would be. Results revealed that in no instance was the most thoroughly personalized condition (Big Five matched) or the alternate way of matching to schema (ideal self-schema) more effective than the actual self-schema matching. When designing PSAs, there appears to be a threshold of personalization. Research related to testing PSAs discouraging binge drinking should continue to pursue self-schema matching rather than the more complicated Big Five matching. Study 2 tested Person Matching (i.e., whether the PSA matches the person's self-schema type or not) and two types of Context Matching (i.e., whether the PSA matches the Topic or Values of the message context) to determine their relative influence on the effectiveness of the PSA. It was expected that PSAs matched to any of these factors would be more effective than messages not matched, and that Person Matching would be more influential on the PSAs effectiveness than the two types of context matching. Person Matching reduced intentions to drink while staying in/home, but Topic Matching reduced intentions to drink when going out, suggesting that different factors are important for PSAs targeting drinking behavior in different locations. The interaction of Topic Matching and Values Matching indicate that the PSA should not match the message context too closely. Again, there appears to be a matching threshold; increasing the number of factors the message matches does not increase message effectiveness, possibly because it makes the message too redundant with the webpage content.

Submitted in fulfilment of the requirements for the Degree of Master of Applied Arts in Fashion, Durban University of Technology, Durban, 2017. / The South African pear-shaped Black women’s jeans market has been confronted by fit dissatisfaction, although there is a growing demand for jeans. This study was approached from a viewpoint that jeans do not fit a large population of this consumer group and investigates the issues related to this problem. Local manufacturers and retailers currently use an adaptation of the British sizing system to suit their customer profile. Not much research however, has been carried out on developing a sizing system for the pear-shaped figure type, which makes up a sizeable portion of the population in the country. The intention of the study was to establish key variables for developing a jeans sizing system for Black South African pear-shaped indigenous women. A total of 60 Black women aged 18-35 years at the Cape Peninsula University of Technology were scanned for body measurements using a 3D body scanner. Body measurement differences were examined by using a quantitative research approach to establish the difference between waist and hip measurements. The findings revealed an average drop value of 39cm between waist and hip circumference for a Black pear-shaped figure, in comparison to a drop value of 24cm for a standardised sizing used by the clothing industry. It is recommended that the major stakeholders in South Africa conduct a national anthropometric study to update sizing systems, by using 3D body scanning technology, which provides accurate and consistent measurements of the human body. / M

Táto práca sa zaoberá prispôsobením (tailoring) mikroštruktúry vybraných pokročilých keramických materiálov (oxid hlinitý, kubický a tetragonálny oxid zirkoničitý) metódou izostatického lisovania za tepla (post-HIPing) s cieľom pripraviť vzorky s teoretickou hustotou and minimálnou veľkosťou zŕn. Vzhľadom na to, že izostatické lisovanie je vo väčšine prípadov používané ako dokončovacia metóda, pred-slinovanie (príprava vzoriek v štádiu uzavretej pórovitosti) bolo tiež dopodrobna študované. Extenzívny teoretický a experimentálny výskum pred-sintrovania pokročilých keramických materiálov ukázal niekoľko výsledkov. Bolo zistené, že uzatváranie pórov je materiálová charakteristika riadená medzi-povrchovými energiami (uzatváranie pórov nastáva pri 92-96 % t.d. pre skúmané materiály), je nezávislé na technológii prípravy keramického polotovaru a je nezávislé na histórii sintrovacieho procesu. Pre analýzu mikroštruktúry skenovacím elektrónovým mikroskopom a výrazné zvýšenie efektivity mikroštruktúrnej analýzy, bola vyvinutá nízkoteplotná metóda termálneho leptania. Táto metóda umožňuje zviditeľnenie leštenej mikroštruktúry pri leptacej teplote 900 °C a výdrži 1 hodina čiastočne sintrovaných a plne hutných vzoriek bez teplotnej kontaminácie (zvýšenie hustoty a veľkosti zŕn). Pred-sintrované vzorky boli post-HIPované nadizajnovaným kombináciami teploty (1200-1400 °C), aplikovaného tlaku (50 a 200 MPa) a času výdrže (0,5 až 9 hodín) s cieľom štúdia vplyvu týchto post-HIPovacích parametrov na mikroštruktúru vzoriek. Najdôležitejší výsledok experimentov je, že aplikovaný tlak vykazuje iba minimálny vplyv na rast zŕn v priebehu post-HIPovania, pričom výrazne posilňuje zhutňovanie. Sintrovacia teplota a čas výdrže tiež vykazovali zhutňovací potenciál, avšak s negatívnym efektom na veľkosť zŕn počas post-HIPovania rešpektujúc kinetickú rovnicu rastu zŕn – exponenciálny rast pre teplotu a parabolický rast pre čas. Tieto výsledky boli použité pre optimalizáciu post-HIPovacích cyklov pre študované materiály. Výsledné vzorky boli zhutnené nad 99,7 % t.d. a s minimálnym (pod 10 %) nárastom veľkosti zŕn v porovnaní s pred-sintrovanou veľkosťou zŕn. Aplikáciou získaných znalostí bola pripravená transparentná korundová keramika dopovaná erbiom s fotoluminiscenčnými vlastnosťami. Pripravená vzorka s tvrdosťou HV 10 26,9 GPa a so skutočnou inline priepustnosťou RIT 56 % vykazuje najlepšie hodnoty tvrdosti a priepustnosti v doposiaľ publikovaných korundových keramických materiáloch dopovaných prvkami vzácnych zemín.

The world is experiencing a rapid rise in chronic health problems, which places an enormous burden on health care services. Modifiable health behaviors such as physical inactivity are largely responsible for this high prevalence and incidence of chronic diseases. Message tailoring is a well-established approach for constructing health communication and has been shown to increase the persuasiveness of messages in the promotion of healthy behaviors. Message framing is an effective strategy that has been well-studied in psychology over the past 20-plus years across a breadth of health-related behaviors but has received little attention in the nursing research literature. Based on prospect theory, temporal construal theory, and motivational orientation theories, the present study examined how two individual differences factors - consideration of future consequences (CFC) and motivational orientation - combine to moderate temporal proximity and valence framing effects on intentions to increase physical activity. A mail survey was conducted using Dillman's Tailored Design Method. Two hundred and eighteen adults with type 2 diabetes were randomly assigned to receive one of four versions of a health message aimed to increase regular physical activity. Messages were framed using a 2 (immediate- vs. distal-framed) x 2 (gain- vs. loss-framed) design. After reading the message, participants rated their intention to increase physical activity. They also completed a measure of CFC and two measures of motivational orientation. Participants who read a message with a temporal proximity or valence frame congruent with their CFC or motivational orientation, respectively, did not show greater intentions to increase physical activity when compared to those who read a health message that was incongruent with these individual differences. Plausible explanations for these negative results are considered. Several interesting findings emerged from supplemental analyses. For instance, participants who perceived the health message as more believable tended to have greater intentions to increase physical activity. Suggestions for future research applying message congruence to promote complex health behaviors in at-risk populations are given. Implications of message framing and other message tailoring strategies for nursing research, education, and practice are discussed.

"Teaching methods have always been of utmost importance to educators. Successful teaching methods are needed for all students, including the mentally handicapped; therefore, more emphasis has been placed on the equality of educational opportunities for more than seven million handicapped children in the United States. It is also important that effective instructional materials and teaching methods be available for all individuals as expressed by Mc-Kay (1973)"--Introduction. / Typescript. / "July, 1977" / Advisor: Bonnie B.
