Friedrich von Hayek: The Socialist-Calculation Debate, Knowledge Arguments, And Modern Economic Development

At the close of the nineteenth and the commencement of the twentieth century, socialism began to gain momentum as a large-scale movement in Europe and the United States. This popularity was supported by an increased influence of the working class in society, which put pressure for representation upon European parliaments and began to secure concrete improvements in labor protection laws. Moreover, socialist proponents looked hopefully towards the living example of the Soviet Union, which began its socialist experiment in 1917 following the success of the Bolshevik Revolution. Socialism, which found its economic grounding in the legacies of such men as David Ricardo and Karl Marx, tended to encourage a more central and vital role for government intervention in the economy. Thus economists who favored a socialist-oriented change in contemporary societies began to develop theories intended to address such issues as “where, when and how the state should intervene in economic life” and how societies might be successfully reorganized so as to be based upon these new precepts.

Designing Spaces for Learning and Living in Schools: perspectives of a 'flaneuse'

The design elements of school learning spaces - classrooms, laboratories, libraries, studios - have the potential to position learners and teachers and to prohibit, authorise, situate and regulate the ways in which learning takes place. Approaches to the designing of learning spaces can fail to take into account the changing social, cultural, pedagogical and technological factors impacting on learners and teachers. How can such taken-for-granted spaces accommodate the needs of learners and teachers and respond to the demands of 'rich task' curriculum and 'real world' learning experiences? Acknowledging Donald Schon's (1983) perspective that 'all occupations engaged in converting actual to preferred situations are concerned with design', this paper is linked to a site visit and workshop conducted in the Ken Thamm Information Resource Centre at Immanuel Lutheran College, Buderim as part of the 2005 Australian Curriculum Studies Conference Blurring the Boundaries – Sharpening the Focus

Evaluation of turbulence induced noise in coherent anti-Stokes Raman scattering

The effect of turbulence in a transonic wind tunnel on coherent anti-Stokes Raman scattering is considered. The driving pump and Stokes waves are taken to be coaxially propagating Gaussian beam waves which are focused on the Raman active medium through the turbulent boundary layer of the flow tube. The random index of refraction variations in the layer are modeled as phase perturbations of the driving waves which cause a reduction of the mean on-axis field and an increase in the mean diameter of the beams. Effective Gaussian beam parameters are developed and the radiated anti-Stokes power calculated as a function of the phase screen parameters. A significant reduction in signal strength occurs for realistic estimates of the phase screen parameter appropriate to a confined transonic flow. A method for estimating the signal degradation which could be applied to other experimental situations is presented

Seroepidemiological studies of herpesvirus-associated diseases of marine turtles: Fibropapillomatosis and lung-eye-trachea disease

We have developed immunological tests that can identify marine turtles in Florida (green and loggerhead) that have been exposed to the LETV herpesvirus. The seroepidemiological data collected provides critical evidence about the relationship between infection with the FP-associated herpesvirus and the LETV herpesvirus. The data supports the hypothesis that LETV and FPHV infections are independent infections of marine turtles. The data shows that wild green turtles in Florida are exposed to the LETD-associated herpesvirus, which is the first description ofLETV infection in free-ranging marine turtles. To our knowledge, the antigenic proteins identified in this study are not only the first proteins from a reptilian herpesvirus to be cloned and expressed, but they represent the first reptilian herpesvirus proteins to be identified as immunogenic in their host species.
