Grace Crowley's contribution to Australian modernism and geometric abstraction

Grace Crowley was one of the leading innovators of geometric abstraction in Australia. When she returned to Australia in 1930 she had thoroughly mastered the complex mathematics and geometry of the golden section and dynamic symmetry that had become one of the frameworks for modernism. Crowley, Anne Dangar and Dorrit Black all studied under the foremost teacher of modernism in Paris, André Lhote. Crowley not only taught the golden section and dynamic symmetry to Rah Fizelle, Ralph Balson and students of the Crowley-Fizelle Art School, but used it to develop her own abstract art during the 1940s and 1950s, well in advance of the arrival of colour-field painting to Australia in the 1960s. Through her teaching at the most progressive modern art school in Sydney in the 1930s Crowley taught the basic compositional techniques as she had learnt them from Lhote. When the art school closed in 1937 she worked in partnership with fellow artist, Ralph Balson as they developed their art into constructive, abstract paintings. Balson has been credited with being the most influential painter in the development of geometric abstraction in Australia for a younger generation of artists. This is largely due to Crowley’s insistence that Balson was the major innovator who led her into abstraction. She consistently refused to take credit for her own role in their artistic partnership. My research indicates that there were a number of factors that strongly influenced Crowley to support Balson and deny her own role. Her archives contain sensitive records of the breakup of her partnership with Rah Fizelle and the closure of the Crowley-Fizelle Art School. These, and other archival material, indicate that Fizelle’s inability to master and teach the golden section and dynamic symmetry, and Crowley’s greater popularity as a teacher, was the real cause of the closure of the School. Crowley left notes in her Archives that she still felt deeply distressed, even forty years after the events, and did not wish the circumstances of the closure known in her lifetime. With the closure of the Art School and her close friend Dangar living in France, her friendship with Balson offered a way forward. This thesis argues that Crowley chose to conceal her considerable mathematical and geometric ability, rather than risk losing another friend and artistic partner in a similar way to the breakup of the partnership with Fizelle. With the death of her father in this period, she needed to spend much time caring for her mother and that left her little time for painting. She later also said she felt that a man had a better chance of gaining acceptance as an artist, but it is equally true that, without Dangar, she had no-one to give her support or encourage her as an artist. By supporting Balson she was able to provide him with a place to work in her studio and had a friend with whom she could share her own passion for art, as she had done with Dangar. During her long friendship with Balson, she painted with him and gave him opportunities to develop his talents, which he could not have accessed without her. She taught him, by discreet practical demonstration the principles she had learnt from Lhote about composition. He had only attended the sketch club associated with the Crowley- Fizelle Art School. Together they discussed and planned their paintings from the late 1930s and worked together on abstract paintings until the mid-1950s when, in his retirement from house-painting, she provided him with a quiet, secluded place in which to paint and experiment with new techniques. With her own artistic contacts in France, she gained him international recognition as an abstract painter and his own solo exhibition in a leading Paris art gallery. After his death in 1964, she continued to promote his art to curators and researchers, recording his life and art for posterity. The artist with whom she studied modernism in Paris, Anne Dangar, also received her lifelong support and promotion. In the last decade of her life Crowley provided detailed information to curators and art historians on the lives of both her friends, Dangar and Balson, meticulously keeping accurate records of theirs and her own life devoted to art. In her latter years she arranged to deposit these records in public institutions, thus becoming a contributor to Australian art history. As a result of this foresight, the stories of both her friends, Balson and Dangar, have since become a record of Australian art history.

Effects of public infrastructure capital on the economic development and productivity of the metropolitan and peripheral regions of Greece: 1976-1992.

The relationship between economic development and public infrastructure capital has puzzled economists, economic geographers, planners, and other social scientists, for many years. This thesis presents an attempt to theorise and conduct empirical research on this field in the context of a developing economy within the European Union - Greece. Key to understanding the work undertaken in this thesis is the wider theoretical and applied research, which has flourished in the US and other countries during the last decade. The thesis examines the effects of public capital investment on Greek economic development viewed at different spatial scales. More specifically, it explores the role of infrastructure spending at national, regional, and urban (metropolitan area of Athens) levels. The empirical presentation begins with a description of the Public Investment Programme from 1976 onwards. This is the main channel for public investment in infrastructure capital in Greece. Its various public capital sub-categories have been aggregated into two basic types, 'productive' and 'social' infrastructure. The next step was to utilise a production function analytical framework and panel data analysis to explore the direct and network effects of infrastructure investment on manufacturing industry. Positive effects of infrastructure spending are apparent. An alternative approach, cost function analysis, is deployed in the second major empirical section. Using various spatial levels, the role of public capital on the private costs of production can be examined by the calibration of a cost function for industrial sectors. The results show that infrastructure investment reduces private costs in manufacturing at most spatial levels. Finally, the thesis investigates other direct and indirect channels by which public capital can affect the non-manufacturing and manufacturing sectors of the private economy. The empirical findings show that there is no significant infrastructure impact on the former sector, whereas there are mixed results for the indirect channels on manufacturing. It can be safely argued that the public capital and regional development relationship is a complex one, especially as infrastructure effects can be different at different spatial levels

Governments, public opinion, and social policy : change in Western Europe

Defence date: 21 November 2022Examining Board: Prof. Ellen Immergut (EUI, Supervisor); Prof. Anton Hemerijck (EUI); Prof. Christoffer Green-Pedersen (Aarhus University); Prof. Evelyne Hübscher (Central European University)This dissertation investigates how public opinion and government partisanship affect social policy. It brings an innovative perspective that links the idea of democratic representation to debates about the welfare state. The general claim made here is that social policy is a function of public and government preferences. This claim hinges on two critical premises. The first relates to the general mechanisms that underlie government representation. Politicians have electoral incentives to align their actions with what citizens want. They may respond to public opinion indirectly by updating their party agendas, which can serve as the basis for social policy decisions in case they get elected. They may also respond directly by introducing welfare reforms that react to shifts in public opinion during their mandates. The second premise concerns how citizens and politicians structure their preferences over welfare. These preferences fall alongside two dimensions. First, general attitudes about how much should the state intervene in the economy to reduce inequality and promote economic well-being (how much policy). Second, the specific preferences about which social programmes should get better funding (what kind of policy). The empirical analysis is split into three empirical chapters. Each explores different aspects of government representation in Western European welfare states. The first empirical chapter (Chapter 4) asks how governments shape social policy when facing severe pressures to decrease spending. It argues that governments strategically reduce spending on programmes that offer less visible and indirect benefits, as they are less likely to trigger an electoral backlash. The experience of the Great Recession is consistent with this claim. Countries that faced the most challenging financial constraints cut down social investment and services. Except for Greece, they all preserved consumption schemes. The second empirical chapter (Chapter 5) explores how public opinion affects government spending priorities in different welfare programmes. It expects government responsiveness to depend on public mood for more or less government activity and the most salient social issues at the time. Empirical evidence from old-age, healthcare and education issue-policy areas supports these claims. Higher policy mood and issue saliency is positively associated with increasing spending efforts. Public opinion does not appear to affect unemployment policies. vii The third empirical chapter (Chapter 6) examines how party preferences affect spending priorities in unemployment programmes. It claims that preferences on economic intervention in the economy and welfare recalibration affect different components of unemployment policy. Evidence from the past 20 years bodes well with these expectations. The generosity of compensatory schemes depends on economic preferences. The left invests more than the right. The funding of active labour-market policies depends on both preference dimensions. Among conventional parties, their funding follows the same patterns as compensatory schemes. Among recalibration parties, parties across the economic spectrum present comparable spending patterns

Essays on Scale and Scope Economies in the English NHS

This thesis considers the relationship between the size and structure of hos- pital services and their costs. It is often assumed that service amalgamation ought to yield lower costs through economies of scale. However, empirical evidence for this is limited and often dated. This thesis is structured as a series of essays evaluating scale and scope economies using parametric methods applied to cost and activity data from the English National Health Service, covering April 2013 - March 2019. The first three empirical chapters consider the relationship between size and average healthcare cost, whilst the last explores how the configuration of services affects the cost of hospital healthcare provision. Several parametric specifications and methods are used to evaluate scale economies using the dataset. Results show small but positive economies of scale for various specifications up until around 1,000-1,200 beds, which constituted most hospitals in the sample. Scale economies after this point varied according to the method used, suggesting that methodology, particularly the choice of the functional form, may partly explain variation in the literature. Differences are observed between the direct estimation of a long-run cost function and a long-run function obtained from the envelope of short-run functions. Scale economies were also lower in London and surrounding areas due to higher wage rates for non-medical staff. The analysis of scope economies found that general surgery demonstrated the highest degree of scope economies compared to all other outputs, with general medicine and obstetrics/gynaecology also exhibiting positive scope economies to a lesser degree. General surgery, general medicine and obstetrics/gynaecology may benefit from lower costs when collocated with other activities. This thesis updates prior estimates of hospital economies of scale using rich data. It provides insights into methodological sources of variation, leading to conclusions of interest for policy in planning hospital service provision and the effects of scale and scope
