Forecasting the onset of the grass pollen season in Melbourne (Australia)

In Melbourne, a southern hemisphere city with a cool temperate climate, the grass pollen season has been monitored using a Burkard spore trap for 12 years (11 pollen seasons, which extend from October through January). The onset of the grass pollen season (OGPS) has been defined in various ways using both arbitrary cumulative scores (Sum 75, Sum 100) and percentages (10% Pollen Fly). OGPS, based on the forecast model of pollen season devised by Lejoly-Gabriel (Acta Geogr. Lovan., 13 (1978) 1–260) has been most widely used in efforts to forecast the beginning of the pollen season. OGPS occurred in Melbourne between 20 October to 24 November (average 6 November), a difference of 35 days. Duration of the pollen season ranged from 46 to 81 days, with a mean of 55 days, one of the longest reported. The relationships between onset and various weather parameters for July have enabled us to modify a model, using linear regression analysis, to predict onset. The prediction model is based on a negative correlation between date of onset and the sum of rainfall for July (a winter month). The error of prediction (Ep) is 24% and predicted day of OGPS was precisely predicted on 2 occasions, and on others with a range of accuracy of 3 to 14 days.

Sir Walter Scott in the western district, 1836-1851

A survey of 30 early settlement squatters in Victoria, using their letters, diaries and memoirs to compile a regional history of colonial readers. The resulting reader-responses support the emerging interpretations of Affective Reading, rather than more conventional strategies of literary criticism (New Historicism and Discourse Analysis).

Civilisation, culture and the hybrid self in the work of Robert Ezra Park

Contemporary discussions on hybridity in cultural and ethnic studies have overlooked the work of the Chicago sociologist Robert E. Park. Park's idea of the “marginal man” and his work on cultural and racial hybridity can shed further light on the construction and representation of the hybrid self. The contribution that Park has made to a social theory of hybridity has been overshadowed by research conducted within post-colonial and cultural studies. I do not suggest that recent conceptualisations of hybridity are inadequate; rather that Park has something to contribute to contemporary accounts and in some cases anticipates some of the themes and issues surrounding the concept of hybridity. The following examination connects Park's work on hybridity with ideas such as civilisation, culture and modernity and argues that a mild form of primitivism underlines his notion of the “marginal man”.

A decision support tool for resource allocation in batch manufacturing

A decision support tool for production planning is discussed in this paper to perform the job of machine grouping and labour allocation within a machining line. The production plans within the industrial partner have been historically inefficient because the relationship between the cycle times, the machine group size, and the operator's utilisation hasn't been properly understood. Starting with a simulation model, a rule-base has been generated to predict the operator's utilisation for a range of production settings. The resource allocation problem is then solved by breaking the problem into a series of smaller sized tasks. The objective is to minimise the number of operators and the difference between the maximum and minimum cycle times of machines within each group. The results from this decision support tool is presented for the particular case study.
