    Continuous improvement (CI) is an important methodology adopted by the public sector, including local government, to drive process efficiencies and outcome effectiveness, often in response to financial pressures and increased customer demands driven by both state and federal governments (Burgess & Radnor 2012; Pedersen 2011; Radnor, Z. 2010; Rashman & Radnor 2005; Suarez Barraza et al. 2009). Moreover, the adoption of neoliberal policies to drive such imperatives has resulted in CI being enacted in ways that are often removed from the practice traditions presented by the early quality theorists of Crosby, Juran, Deming and Imai. The decontextualised approach to CI has seen the implementation of a range of quality frameworks, such as Australian Business Excellence or Lean Thinking, being implemented. The introduction and adoption of such frameworks has often been met with cynicism and caution by both CI practitioners and staff, as organisations have not always achieved the sought after gains frequently promised. For local government, CI practices have come to mean the application of a narrow range of tools. Most recently, the traditions, practices and frameworks which have been the foci on improvement have shifted to see the implementation of yet a new framework, which in the context of NSW local government has come to be known as service reviews (see for example: Pepper et al. 2021; University of Technology 2020, 2021) as the gold standard that has worked to reconfigure how CI is enacted within the NSW local government. This research explores ways in which, for NSW local government contexts, the fundamental activity and CI practice of problem definition could be reconfigured in ways which bring it closer to practice traditions of seminal theorists such as Deming and Imai. In this thesis the literatures of action learning sets (Anderson and Thorpe 2004; Bird and Duffy 2021; Norman 2016) and CI are brought together to foreground problem definition statements, action and critical reflection and the essential nature of these in the day-to-day enactment of CI practice within NSW local government (see for example Crosby 1989; Deming 1986; Ghobadian and Speller 1994; Imai 1986; Juran 1995). Through the introduction of action learning set practices at a number of NSW local government sites, this research has foregrounded the relational complexity of CI that enacted neoliberalist policies have ignored. In bringing workers together to enact practices of problem definition, action and reflection, the Action Learning Sets (ALS) have emerged as sites where it is possible to reinstate or indeed reinvigorate the lost practice traditions of CI

    Doctor of Philosophy in Biology. University of KwaZulu-Natal, Durban 2015.The effects of bunker fuel oil on the growth of A. marina, B. gymnorrhiza and R. mucronata were investigated in glasshouse and field experiments. The effects of oil on community structure in micro-organisms were also investigated in microcosm glasshouse experiments. The differences in oil tolerance of the three mangroves were compared in propagule and sediment oiled treatments and growth monitored for 13 months under glasshouse conditions. In propagule oiled treatments, various portions of the propagule were coated with oil. In the sediment oiled treatments, 50ml oil were added to the sediment in each pot. In oiled treatments, plant height, number of leaves and chlorophyll content were significantly reduced in all species compared to the control. In A. marina and R. mucronata, oiling resulted in growth malformations such as abnormal phyllotaxy and deformity of leaves and stems. The effects of oil on root growth were investigated in rhizotrons for 245 and 409 days respectively. In oiled treatments, root growth rate, length and volume were significantly reduced in all species. In A. marina and B. gymnorrhiza oil increased root diameter. In another series of experiments, PAH accumulation in roots and leaves of the three species were determined in one year old seedlings subjected to oiling for 21 days. The concentrations of 15 PAHs in roots and leaves were determined by gas chromatography / mass spectrometry. The highest total concentration of PAHs was accumulated in oiled roots of A. marina (44,045.9Ī¼g/kg), followed by B. gymnorrhiza (10,280.4Ī¼g/kg) and R. mucronata (6,979.1Ī¼g/kg). In oiled treatments, the most common PAHs in roots of all species were fluorene and acenaphthene (two rings), phenanthrene and anthracene (three rings), pyrene and chrysene (four rings) and benzo[a]pyrene (five rings). In the leaves of all species in oiled treatments, the common PAHs were naphthalene and acenapthene (two rings) and phenanthrene (three rings). To test for living and dead root tip cells and to compare the effects of oil on cell ultrastructure in roots and leaves of the three species, one year old seedlings were subjected to a control and sediment oiled treatments for seven days. Control root tips, stained with fluorescein diacetate, exhibited green fluorescence in living cells of the meristematic and conducting tissue in all species. Oiled root tips, stained with propidium iodide, exhibited red fluorescence, indicating cell death or dead cells. Transmission electron micrographs revealed that oil damaged cell ultrastructure in root tips and leaves in all species. Anatomical changes induced by oil included, disorganization of cells in the root cap, epidermis and meristem. Oil also induced loss of cell contents and destruction of organelles in root tissue. Oil damaged chloroplasts and cell organelles in spongy mesophyll and palisade cells of leaves. To compare the effects of oil on the ability of the three species to tolerate salinity, healthy one year old seedlings were subjected to 10% and 50% seawater in control and sediment oiled treatments for 12 months. In the oiled treatments, 200ml oil were added to the soil in each pot. Oil significantly reduced growth in the 50% seawater treatment in all species. Results suggested that oil reduces salt tolerance in the three species. The effects of oil on salt secretion in A. marina were investigated by subjecting one year old seedlings to sediment oiling treatments at 0%, 10% and 50% seawater for three weeks. Sodium accumulated in the leaves of oiled seedlings at 10% and 50% seawater. The effects of oil on salt secretion in A. marina in the light and dark were compared in one year old seedlings subjected to oiling treatments for seven days. Sodium accumulated in the leaves of oiled seedlings in the light and dark within 11 hours. Oil reduced secretion rates of Naāŗ, Kāŗ, CaĀ²āŗ and MgĀ²āŗ in all treatments. The effects of oil on species abundance, richness and community structure of soil micro-organisms were determined by subjecting microcosms to oiling treatments with or without fertiliser for four weeks. In the oiled treatments, 15ml oil and 5ml/L fertiliser were added to 200g soil. Fertiliser consisted of 4% N, 2% P and 5% K. Nematodes were extracted after the experimental period and identified to genus or species level. Oil significantly reduced species abundance and richness. Oil also eliminated sensitive species and altered the abundance of dominant species thereby altering the free living nematode community structure. Addition of fertiliser increased richness and dominant species in oiled treatments. The effects of oil coating on leaves and internodes on growth of the three mangroves were investigated in field experiments for 48 weeks. Oiling of the leaves resulted in leaf abscission and decreased leaf production in all species. The effects of sediment oiling (at a dose of 5LmĖ‰Ā²) on the three species were also investigated in a field study for 53 weeks. In A. marina, oil caused adventitious roots to develop on the stem, about 10-15 cm above the soil surface after 38 weeks of treatment. In oiled treatments, plant mortality occurred after 53 weeks in all three species. The ability of B. gymnorrhiza and R. mucronata to exclude PAHs from sensitive root tissues probably accounted for the higher oil tolerance than A. marina. The capacity of the species to adapt to residual oil contamination by increasing root diameter (A. marina and B. gymnorrhiza), producing adventitious roots (A. marina), increasing root/shoot ratio (R. mucronata) and abscising oiled leaves (all species) probably contributed to oil tolerance

    Commons in Design

    The scarcity of resources, climate change, and the digitalization of everyday life are fuelling the economy of swapping, sharing, and lendingā€”all of which are in some way linked to a culture of commoning. In this context, we understand commons as community-based processes that use, collectively manage, and organize generally accessible resourcesā€”referring to both goods and knowledge. Commons in Design explores the meaning and impact of commonsā€”especially knowledge-based peer commonsā€”and acts of commoning in design. It discusses networked, participatory, and open procedures based on the commons and commoning, testing models that negotiate the use of commons within design processes. In doing so, it critically engages with questions regarding designersā€™ positionings, everyday practices, self-understandings, ways of working, and approaches to education

    The assessment of undergraduate final year projects : a study of academic professional judgment

    Bibliography: leaves 213-218.The premise of this study is that the assessment of student performance is an interpretive process. This raises a fundamental validity question: on what basis do academic communities evaluate the soundness of their interpretations? The central problem which this study explores is how academic assessors validate their interpretations of student performance on complex tasks. I explore this problem by focusing specifically on the assessment of final year undergraduate projects through two case studies of disciplinary communities of practice, one in the Humanities faculty and the other in the Engineering faculty of a South African university. Drawing on Bourdieu's theory of social practice on the one hand, and the methods of critical discourse analysis and ethnography on the other, I construct a theory and method of inquiry which illumines aspects of assessment as an interpretive process, aspects which have been obscured by traditional approaches to assessment. This analysis privileges the context of assessment, the inevitability of difference in assessment interpretations and the equally inevitable effects of power. My methodological approach identifies four elements which constitute social practice- social structure, conjuncture. event and text. These constitutive elements operationalize into a series of analytical stages which expose different aspects of social practice. My approach is consistent with Fairclough's method of critical discourse analysis, although I also include ethnographic methods
