Pile- Exhibition curated by Craig Fisher

This enquiry extends previous investigations exploring the relation between pattern, decoration and formalist abstraction, addressing painting’s capacity to establish a ‘visual pulse’, enabling a re-interpretation of both a previous painting and a body of new paintings/drawings. The work was selected for a comprehensive sculpture exhibition that questions the conventions of group exhibitions. Ways in which painting’s autonomy is examined through display and proximity to the work of others are explored. Mother in Law’s Tongue, a three-panelled painting on domestic door blanks, connected floor and wall – both siting and object/image address the boundary between painting and sculpture. The hierarchy of fine art over decorative arts is challenged: the painting used as a device on which to hang the work of another artist, risking that the work might be seen as a decorative prop. Previous research using repetition and difference as a means to invoke a visual pulse in painting was re-visited in a new body of paintings on paper, continuing investigations of relations between internal mark-making, in relation to frame, size and scale, and parameters of substrate. The project restricts colour to its constitute subtractive primaries (magenta, yellow, and cyan), which then enables the exploration of a set of permutations and combinations. The resulting paintings are constructed through a repetitive process, engaging the viewer in the rhythm and craft of production, producing a hypnotic quality, making the work seem more ‘alive’ than the methodical nature of production might suggest. The slippage between systematic abstraction and pattern suggests an in-between space, uncertain and open to interpretation. Earlier stages of this research include: a group exhibition Trick of Light, Primo Alonso Gallery, London, 2010, curated by Juan Bolivar; and two chapbooks in the series Transmission Hospitality (London: Artwords, 2010, 2011) – from the second, a visual and textual dialogue with the artist Jane Harris, the saturated works above developed

Fiscal Shocks and Their Consequences

This paper investigates the response of hours worked and real wages to fiscal policy shocks in the U.S. during the post World War II era. We identify these shocks with exogenous changes in military purchases and argue that they lead to a persistent increase in government purchases and tax rates on capital and labor income, and a persistent rise in aggregate hours worked as well as declines in real wages. The shocks are also associated with short lived rises in aggregate investment and small movements in private consumption. We describe and implement a methodology for assessing whether standard neoclassical models can account for the consequences of a fiscal policy shock. Simple versions of the neoclassical model can account for the qualitative effects of a fiscal shock. Once we allow for habit formation and investment adjustment costs, the model can also account reasonably well for the quantitative effects of a fiscal shock.

Network Access Control: Disruptive Technology?

Network Access Control (NAC) implements policy-based access control to the trusted network. It regulates entry to the network by the use of health verifiers and policy control points to mitigate the introduction of malicious software. However the current versions of NAC may not be the universal remedy to endpoint security that many vendors tout. Many organizations that are evaluating the technology, but that have not yet deployed a solution, believe that NAC presents an opportunity for severe disruption of their networks. A cursory examination of the technologies used and how they are deployed in the network appears to support this argument. The addition of NAC components can make the network architecture even more complex and subject to failure. However, one recent survey of organizations that have deployed a NAC solution indicates that the \u27common wisdom\u27 about NAC may not be correct

Fiscal shocks in an efficiency wage model

This paper illustrates a particular limited information strategy for assessing the empirical plausibility of alternative quantitative general equilibrium business cycle models. The basic strategy is to test whether a model economy can account for the response of actual economy to an exogenous shock. Here we concentrate on the response of aggregate hours worked and real wages to a fiscal policy shock. The fiscal policy shock is identified with the dynamic response of government purchases and averages marginal income tax rates to an exogenous increase in military purchases. Burnside, Eichenbaum and Fisher (1999) show that standard Real business Cycle models cannot account for the salient features of how hours worked and after - tax real wages respond to a fiscal policy shock. In this paper we show that this failure extends to a class of business cycle models in which the labor is characterized by efficiency wages.Fiscal policy ; Wages

Fiscal Shocks in an Efficiency Wage Model

This paper analyzes the ability of a general equilibrium efficiency wage model to account for the estimated response of hours worked and of real wages to a fiscal policy shock. Our key finding is that the model cannot do so unless we make the counterfactual assumption that marginal tax rates are constant. The model shares the strengths and weaknesses of high labor supply elasticity Real Business Cycle models. In particular it can account for the conditional volatility of real wages and hours worked. But it cannot account for the temporal pattern of how these variables respond to a fiscal policy shock and generates a counterfactual negative conditional correlation between government purchases and hours worked.

Developing business community portals for SMEs-Issues of design, development and sustainability

Governments worldwide are using funding initiatives to encourage small businesses to adopt e-commerce technology. In Australia both State and Federal Governments have encouraged e-commerce uptake through the funding of Internet portal developments that have a specific community or business focus. The success of such portals, as with many Web developments, has been mixed and there is little evidence of any evaluation of the effectiveness of such investments. This paper reports on research into an Australian B2B business community portal from launch to closure. A survey and in-depth interviews with portal participants were undertaken. The research sought to understand how the portal had been developed, and what factors may have contributed to its demise. The findings identified a number of factors, not discussed in the literature, that are important in portal development. These include: how the development process is undertaken; technological readiness of the small business owners; meeting business expectations; and understanding the business community stakeholders. The results from this study suggest that portal projects such as this are problematic and funding bodies such as governments need to understand the factors that contribute to success before funds are committed.<br /

From websites to portals: success factors For business community portals

Many Governments are using funding initiatives to encourage businesses, particularly small businesses to adopt e-commerce technology. One currently popular approach in Australia, has been to fund internet portal developments with a specific community or business focus. The success of such portals however, as with many Web developments has been mixed. This paper reports on the establishment of a B2B portal in Australia. The paper explores issues and expectations from the perspective of the business people involved. A survey was conducted amongst the participants of the portal shortly after it was launched. Then follow-up interviews were conducted with business owners 2 years later just before the portal closed. The researchers sought to understand what the business community expected from the portal and to identify what factors contribute to success. The research found that in addition to the factors identified through the literature that, technological readiness of business owners, understanding the business community, realizing business value and managing participant&rsquo;s expectations are also factors impacting on success. A model is proposed to describe the success factors.<br /

Moving from a web presence to e-commerce : the importance of a business-web strategy for small-business owners

More than half of small businesses in Australia (57%) use a website to promote their business. Having an effective website is an important step for small business owners moving towards e-commerce. The research suggests that once a business has a clear online strategy through a website they are more likely to move to e-commerce. While many small business owners have a business strategy, it is often the case that this strategy does not include their Web presence. This paper describes the results of interviews with small business owners and assessment of their websites. We identify elements that are important for small business owners developing a business-Web strategy. The research indicates that many owners see their websites as little more than an advertising medium and few are ready for the move to e-commerce. Identifying the level of maturity of a small business owner\u27s business-Web strategy however can help us understand how prepared a small business owner is to move to e-commerce.<br /

Evaluating small business web sites-understanding users

The cost of developing a website can be considerable and there is ample literature describing how to build effective websites. However, despite this many small businesses embark on the development of a website without any real understanding of what they are trying to achieve, who their audience is and the impact poor design will have on usability and user satisfaction. This paper discusses the results of a study that examined user reactions to a number of small business web sites. In particular it explored the interaction of different design factors on users. The study found that in many cases the websites are not meeting the needs of their audience. Specifically users become frustrated when attention is not paid to the design and quality of the information, the quality of the interface impacts on task completion and sites users find uninteresting are usually those they also had difficulty navigating and interacting with. Whilst none of this should be surprising, what is surprising is the continuing lack of attention paid to website usability.<br /
