This dissertation documents the research involved in determining an appropriate response for the design of a building which serves to provide tools for empowerment and independence for blind and partially sighted people. Primary and secondary data collection methods are used. Secondary data collection forms the majority of information gathered focusing on precedent and case studies. The studies investigate how buildings are currently occupied, discussing the differences between buildings that have been specifically designed for the visually impaired and those that have not. Analysis observes the problems that exist and what solutions have been proposed to overcome these. Design criteria can focus on detail design exclusively; however the building in its entirety can be custom-designed to meet the needs of the visually impaired user. This dissertation explores architecture as a sensory experience, highlighting findings that can be used when designing buildings specifically for visually impaired users. The visually impaired rely heavily on their senses enabling them to interpret their surroundings. This research includes an exploration into the use of the senses within the built environment and how we as sighted designers can understand, interpret and contribute to a visually impaired person's experience of the built environment. The research concludes on an appropriate response to designing for visually impaired people. Conclusions are drawn and a design brief for a facility for a Society for the Blind derived. / Thesis (M.Arch.)-University of KwaZulu-Natal, Durban, 2008.

This thesis presents a new transformative manufacturing methodology for free-form machining. An experimental prototype machine is constructed to levitate and rotate an object attached with sharp edges, which act as a cutter for the purpose of performing machining processes. This device aims to lead to a technological breakthrough, overcoming the limitation of the workpiece features, and achieve greater free-form machining capability. The construction of curved holes and interior surfaces are constrained by the geometry of the machine tool. The proposed concept creates a new device that uses a magnetic field generator as a base. It is loaded with a constant power imposing a vertical physical force to balance gravity and stabilize the cutting tool. With the uniqueness of a preferred orientation between the tool and the base, a rotating surface placed below the base permits the rotation of the cutting tool in order to achieve desired tool rotation speed. A smooth and controlled cut is achieved on a soft material. The result shows the feasibility of the device to achieve similar outcomes as a machine tool.

The purpose of this study was to make a detailed study and analysis of a selected number of alternative schools or programs. The institutions were studied in terms of their development, their offerings, and their successes or failures.The population of the study consisted of 156 program directors who returned usable questionnaires and five program directors whose programs were visited and studied by the investigator. Two instruments were used to secure the data for the study. Each of the two instruments contained thirty-two items with basically the same information. The first instrument was a questionnaire which was mailed to 200 program directors. One hundred fifty-six of the 200 program directors surveyed returned usable responses. The second instrument used to secure data from the directors of five programs identified for on-site visits was an interview guide. Selected findings derived from the questionnaire data included the following: 1. The majority of the 156 alternative programs whose directors responded reported that their 2 programs were for problem students mainly dropouts, potential dropouts, truants or pregnant girls. 2. Most programs whose directors responded were initially and currently funded by school districts in which they are located. 3. Forty-five and five-tenths percent had less than 99 students while 7.1 percent had more than 500 students in each. 4. Among some of the problems cited by directors were: absenteeism, students' lack of sense of direction, students' lack of future plans, lack of program funds, and lack of adequate facilities. Some of the findings derived from on-site data were summarized as follows: The five programs were controlled by the public school systems in which they were situated. In each of the five programs teachers and directors were in charge of the programs' daily governance. The five programs studied had a mixture of conventional and alternative education course offerings. 4. Directors reported an improved rate of school attendance among students. Some of the conclusions developed from the study included the following: Alternative schools or programs are a result of a need to provide options for students and parents. 2. Alternative education provides opportunities to students who cannot be accommodated by conventional public schools.3. Lack of adequate funds seems to be a common problem among alternative school programs. 4. Most chief administrators of alternative programs are responsible for hiring teaching staff members. Following are some of the recommendations made for further research in the area of alternative education: 1. There is need for further research in the area of program longevity to determine specifically why many programs are defunct after being in existence for less than five years. 2. Further research is needed to determine the unique qualities that an alternative program teacher should possess. 3. There is a need for further research in the area of alternative program success. 4. There is a need for further research regarding the desirable qualities of an effective alternative program director.

The Rev. John Howard Shakespeare was General Secretary of the Baptist Union of Great Britain and Ireland from 1898 until his resignation on the grounds of ill health in 1924. This thesis describes and evaluates changes in the Baptist denomination in England during that period, and assesses the significance of Shakespeare’s contribution. Following summaries of the history of Baptist ecclesiology and Shakespeare’s personal background, the main areas of denominational reform are described. The first of these is the strengthening of the Baptist Union and the expansion of its influence, which was the major feature of the period up to about 1908. This presented a challenge to the Baptists' traditional congregational church polity. The second is the changing approach to the recognition and support of Baptist ministers within the denomination, culminating in the 1916 Baptist Union Ministerial Settlement and Sustentation Scheme. The third is Shakespeare's search for church unity, both within Nonconformity and between Nonconformists and the Church of England, which dominated the post-war period. The formation of the Federal Council of the Evangelical Free Churches, of which Shakespeare was the first Moderator, in 1919, and conversations following the 1920 Lambeth Appeal, were central elements of this search. It had significant implications for Baptist church polity. Shakespeare's approach to the question of women in the ministry, and the circumstances surrounding his resignation, are also described. A final chapter discusses Shakespeare's legacy for Baptists. The institutions he created have played an important part in the subsequent history of Baptists and Nonconformity in general. However, they failed to achieve his objective of stemming numerical decline. They also exacerbated tensions in Baptist church polity between the centralisation of denominational life and Congregationalism. These tensions have been a major factor in Baptist church life throughout the present century.

The overarching aim of this thesis was to describe the ecology of the assemblages of free-living nematodes in the sediments of nearshore marine and estuarine waters on the microtidal lower west coast of Australia. The thesis also provides descriptions of ten previously undescribed species as well as develops and tests a habitat classification scheme for the Swan River Estuary using these biotic assemblages. The first section of my thesis has determined the ways in which the characteristics of the nematode assemblages in nearshore marine waters along the microtidal lower west coast of Australia are related to habitat type, time of year and shore-perpendicular zones. Three habitat types, which had previously been identified on the basis of a suite of enduring environmental characteristics, could be broadly described as highly sheltered from wave activity and containing dense seagrass (habitat type 1), moderately sheltered from wave activity and with sparse seagrass (habitat type 2) and relatively exposed to wave activity and with no seagrass (habitat type 6). Sampling in five consecutive seasons yielded > 15 000 nematodes, representing 75 species. The number of species and densities in habitat type 1, and particularly those in its subtidal zone, were far greater than those in the other two habitat types. Both of these biotic variables underwent marked seasonal changes, declining to low levels during winter. The compositions of the assemblages differed significantly among the three habitat types, with the differences between habitat types 1 and 6 being particularly marked. Paracomesoma sipho, Dichromadora sp., Marylynnia annae and Pomponema sp., which, on the basis of their buccal cavity morphology, are assumed to feed primarily on benthic diatoms, were particularly abundant at the most sheltered habitat type, whereas Gonionchus australis, Theristus sp. and Bathylaimus australis, which are assumed to be deposit feeders, were relatively abundant at the most highly exposed habitat type. The compositions of the assemblages differed among seasons and were most discrete in spring, due to marked increases in the densities of certain species. However, differences in the compositions in the different zones of each habitat type were relatively small, presumably reflecting the influence of the small tidal regime of this region. The second component of this thesis has determined the ways in which the density, number of species, species composition and trophic structure of free-living nematode assemblages in the subtidal waters of a large microtidal estuary change spatially and temporally, and has explored whether those four biotic characteristics are related to certain environmental factors. Based on data derived from samples collected seasonally at 12 sites throughout the estuary, the densities and number of species of nematodes decreased progressively with distance from estuary mouth, to reach a minimum at sites where salinities were most variable, and then increased slightly in the uppermost part of the estuary where salinities were least. Densities were also generally greatest in spring, due largely to increases in the abundance of epistrate-grazing species at the time when the amount of primary food (microphytobenthos) peaked. The spatial distribution of the composition of the nematode assemblages was closely correlated with salinity and, to a lesser extent, grain-size composition and amount of particulate organic material in the sediment (%POM). Although species composition changed sequentially along the estuary, the change was particularly pronounced between sites above and below the area where salinities started to decline markedly and become more variable and %POM increased markedly. This reflected, in particular, far greater abundances of Spirinia parasitifera at the six downstream sites, and of Theristus sp. 1 at the six sites further upstream. Species composition underwent pronounced seasonal cyclical changes at all sites, presumably reflecting interspecific differences in the timing of peak reproduction and thus of recruitment. The trophic structure of the nematode assemblages changed both spatially and temporally in relation to the relative abundance of different food sources. Thus, for example, non-selective deposit feeders, such as Theristus sp. 1, dominated samples in the upper estuary, where %POM was by far the greatest, and was rare or absent at downstream sites. Conversely, epistrate grazers, such as species of the Chromadoridae, were most abundant at downstream sites in spring, when the density of the microphytobenthos reached its maximum. The data for the nematode assemblages in nearshore subtidal marine sediments of the lower west coast of Australia were compared with those in nearshore subtidal sediments in the upper and lower regions of the Swan River Estuary. The densities and average species richness in cores from the marine environment were much lower than in cores from both estuarine regions. However, the total number of species found in the marine environment was much greater than in the estuary. The compositions of the nematode assemblages were more variable in marine than estuarine sediments. The assemblages from the two estuarine regions were far more similar to each other than to those from the marine region at a species level, and also, but to a lesser extent, at the generic and family levels. While the trophic compositions of the nematode assemblages in the upper estuarine region was dominated by non-selective deposit feeding species and those of the lower estuarine region were dominated by epistrate grazing species during spring and non-selective deposit feeding species in other seasons, the dominant functional feeding groups varied among the sites representing the marine region. That variability presumably reflects differences in the relative contributions of the different potential food sources. Surprisingly, the trophic composition in the upper estuarine region, i.e. comprising predominantly non-selective deposit feeders, was similar to that at the very different environment of the most exposed marine site. The dominance of this feeding group at the marine site is assumed to be attributable to the fact that the only food source of any note is POM and, even then, it occurs in only small amounts. Taxonomic descriptions have been produced for ten new species of nematodes found during the ecological studies of the free-living aquatic nematofaunas of south-western Australia. These species were chosen because they were members of families for which the other species had been described and, in a number of cases, were important for distinguishing between the compositions of a priori groups. They comprised four species of Axonolaimidae, representing the genera Ascolaimus, Parascolaimus, Odontophora and Parodontophora, and six species of Desmodoridae, representing single species of Bolbonema, Eubostrichus, Catanema and Leptonemella and two species of Onyx. As a complement to the nematological study of the Swan River Estuary, a novel habitat classification system was developed and then applied in this environment. This system was based on enduring environmental characteristics and employed the relatively new multivariate statistical routines SIMPROF and LINKTREE. The applicability of habitat types produced by this classification system to biotic assemblages was tested using the data for the estuarine nematode assemblages described above. The results demonstrate that the compositions of the assemblages differed significantly among each of the habitat types defined by the classification system. While there were also significant differences between the compositions of the nematofaunas at sites belonging to the same habitat type, the extent of these differences were generally less than those between habitat types. A significant and strong correlation was also found between the spatial pattern exhibited by the environmental characteristics used to define habitat types, and that of the nematofauna.
