Today, many organisations are adopting offices that have an open design with or without flexible seating. While advocates of open-plan offices propose that these office types lead to cost savings and aid inter and intra-team communication, opponents argue that these office types are associated with decreased performance and worsened health among employees. This thesis investigates how the type of office (cell offices, shared room offices, small open-plan offices, medium-sized open plan offices, large open-plan offices and flex offices) influences employee health and performance, and whether this is different for different personalities and jobs with different concentration demands. Data were gathered by means of surveys and cognitive tests from five organisations with different office types. In Study I (N=1241), the aim was to investigate the main effect of office type on indicators of health and performance and the interaction effect of office type with the need to concentrate in order to carry out work tasks. Office type alone was associated with distraction and cognitive stress in such a way that cell offices were associated with fewest problems, followed by flex offices, while open-plan offices were associated with the most problems. While employees in open-plan offices and employees in flex offices reported more problems as the need for concentration increased, employees in cell offices reported the same level of problems regardless of the need of concentration. Study II (N=527) investigated how performance on a memory test was affected during normal working conditions as compared to a quiet baseline. There was a negative dose-response relationship between the size of the open-plan office environment and the drop in word recall during the normal working condition. However, Study II also showed that individuals working in cell offices had as high a drop in performance during normal working conditions as did those working in large open-plan office environments. Study III (N=1133–1171) focused on the interaction effect between office type and individual differences in personality. The personality trait agreeableness interacted with office type on the outcome variables distraction and job satisfaction. Specifically, Study III may indicate that as offices get more open and flexible, agreeable people will report more problems. In conclusion, the studies in the present thesis have implications for practice and suggest that office type impacts on employee health and performance, while concentration demands of the job and agreeableness moderate the effects. Although employees report higher level of distraction in open-plan office environments, when performance on a demanding task is measured, cell offices are not as favourable during normal working conditions as self-reported data usually indicate. Organisations should also be aware that, among open-plan offices, small open-plan offices are associated with fewer problems. / Kontorslandskap med eller utan fasta arbetsstationer förekommer idag i många organisationer. Förespråkare för kontorslandskap hänvisar till kostnadsbesparing samt förbättrade förutsättningar för kommunikation, medan motståndare hävdar att kontorslandskap leder till försämrad prestation och hälsa bland medarbetarna. Denna avhandling undersöker om kontorstyp påverkar de anställdas hälsa och prestation, samt om effekten av kontorstyp varierar beroende på de anställdas personlighet och typ av arbetsuppgifter. Data i form av enkätsvar och prestation på kognitiva tester samlades in från fem organisationer med olika typer av kontorslösningar (cellkontor, delade kontorsrum, små kontorslandskap, mellanstora kontorslandskap, stora kontorslandskap och flexkontor). I studie I (N = 1241) var syftet att undersöka huvudeffekten av kontorstyp på indikatorer för hälsa och prestation samt om effekten är beroende av koncentrationskraven i arbetet. Kontorstyp visade samband med distraktion och kognitiv stress på så sätt att medarbetare i cellkontor uppgav minst problem, följt av de i flexkontor, medan kontorslandskap var förknippade med mer problem. Vidare rapporterade anställda som hade arbetsuppgifter som krävde koncentration mer problem i kontorslandskap och flexkontor, medan anställda i cellkontor, oavsett arbetets krav, rapporterade lika mycket problem. I studie II (N = 527) undersöktes hur prestation på ett minnestest påverkades under normala arbetsförhållanden jämfört med en tyst referensmätning i olika kontorstyper. Det fanns ett negativt dos-responssamband mellan storleken på kontorslandskapet och hur många procent sämre medarbetare presterade under normala arbetsförhållanden. Men Studie II visade också att personer som arbetar i cellkontor hade ett lika högt bortfall i prestation under normala arbetsförhållanden som de som arbetade i stora kontorslandskap. I studie III (N = 1133-1171) låg fokus på interaktionseffekten mellan kontorstyp och personlighet. Vänlighet var den enda personlighetsvariabeln som interagerade med kontorstyp på utfallsvariablerna distraktion och arbetstillfredsställelse. Mer specifikt visade Studie III att när kontoret blir mer öppet och flexibelt, så rapporterar människor som skattar sig högt på personlighetsvariabeln vänlighet fler problem. Resultaten i avhandlingen kan få flera praktiska implikationer då den visar att kontorstyp påverkar medarbetarnas hälsa och prestation, medan koncentrationskrävande arbetsuppgifter och vänlighet modererar effekterna. Vidare visar avhandlingen att även om anställda rapporterar mindre distraktion i cellkontor jämfört med i kontorslandskap, behöver inte cellkontor vara lika gynnsamma som självskattade mått visar när prestationen mäts med objektiva mått under normala arbetsförutsättningar, i det här fallet ett minnestest. Slutligen bör organisationer även vara medvetna om att avhandlingen visar en viss tendens att små kontorslandskap är förknippade med mindre problem än stora. / <p>At the time of the doctoral defense, the following paper was unpublished and had a status as follows: Paper 3: Manuscript.</p>

This thesis considers the nature of primary, intermediate and district high school buildings designed by the Building Department of the Canterbury Education Board from its consolidation in 1916 until its termination in 1989. Before 1916, the influence of British models on the CEB’s predecessors had been dominant, while after that date, Board architects were more likely to attempt vernacular solutions that were relevant to the geographic situation of the Canterbury district, the secular nature of New Zealand education and changing ideas of the relative importance of the key architectural drivers of design i.e. function and form. One development, unique to Canterbury, was that for a short period, from 1924-29, a local pressure group, the Open Air Schools’ League became so powerful that it virtually dictated the CEB’s design policy until the Board architects George Penlington and John Alexander Bigg reassumed control by inflecting the open-air model into the much acclaimed veranda block. The extent to which Board architects had the freedom to express themselves within a framework of funding control exercised by the Department of Education was further circumscribed by successive building codes that, at their most directive, required national standardisation under the 1951 Dominion Basic Plan and to a slightly lesser extent under the1956 code and associated White Lines regime. Following World War 2, the use of prefabricated structures had prompted the recognition that better designed relocatable rooms could hold the key to a more flexible and effective allocation of resources in an environment increasingly subject to rapid demographic change. By the end of the period, the exploitation of new construction technologies and modern materials led to the dominance of the relocatable CEBUS buildings in Canterbury schoolyards. A concurrent development was the response of architects A. Frederick (Fred) McCook and John Sinclair Arthur to the Department’s call to design more flexible spaces, i.e. open planning, to facilitate a change in pedagogical method. Other issues raised in this study are the CEB’s solutions to the challenges of building on the West Coast, and the recurring need to ensure structural integrity in a region where there was a continuous risk of seismic activity.

iDuring the past twenty years, China has been making dramatic progress in both the quality and the quantity of collective housing construction. However, many old problems still exist, and many more new problems have emerged, especially in some historical and compact but now fastgrowing cities, such as Suzhou, a 2500-year historic city with more than one million people.The objective of this study is to explore a design strategy to improve the collective dwelling environment --- the most popular dwelling type in China today --- in such a fast growing context. In order to provide an improvement in urban dwelling environments for residents, it is necessary to rethink the interaction between the individual resident and his or her dwelling. "Because building a house is a cultural phenomenon, its form and organization are greatly influenced by the cultural milieu to which it belongs."' In concurrence with this statement, this study examines not only the contemporary urban situation and typical residential environment but also the traditional urban fabric and housing settlement.Based on the principle that a harmonious environment results from "a whole range of sociocultural factors"Z, this study seeks several equilibriums: between the urban tissue and the building, between the building and the dwelling, between nature and the human being. The author's longterm goal is to apply the knowledge gained in this study in future practice.In the first part of this report, theoretical research is presented concerning the evolution of Chinese housing. Narrowing its geographical focus, this study selects Suzhou, a medium-size city at Yangtze Delta --- one of the most rapidly growing and developing plains in China --- as the site for the study. The historical dwelling pattern and current public housing style have been studied. Drawing on extensive research and field observation, the scope of the study is confined to rebuilding the harmony between human beings in all their diversity and common needs, and the morphological, functional and environmental aspects of residential environments.In the second part, a design model is proposed. Inspired by traditional interdisciplinary design strategies, as well as by a brief study of contemporary social needs, the author has proposed a new housing type: bio-climatic "atrium type" collective housing. This type links bioclimatic design principles to the framework of Open Building. On this basis, an experimental design proposal is next presented. In a specific site, it examines a way to help people exercise control of their immediate living environment, with both individual and social sustainable perspectives in mind. / Department of Architecture

This study constitutes an attempt to describe and analyse the quality of selected early childhood development programmes in South Africa, and provide criteria by which the quality of programmes could be assessed. The need for, and importance of, providing quality early childhood development programmes is highlighted. The influence of educational pf:lilosophies on programmes is recognised, hence the total development of the child and educational philosophies related thereto are discussed. Factors and components within programmes that contribute to high quality are explored. Moreover, criteria by means of which quality early childhood development programmes may be assessed, are provided. In this regard criteria for the formulation of aims, selection and the organisation of content, assessment, role of the teacher and parent involvement in programmes are suggested. It is against these criteria that selected early childhood development programmes in South Africa are described and analysed. programmes conclude the study. / Curriculum and Instructional Studies / M.
