Sexual segregation in western grey kangaroos: testing alternative evolutionary hypotheses

In sexually dimorphic ungulates, sexual segregation is hypothesized to have evolved because of sex-specific differences in body size and/or reproductive strategies. We tested these alternative hypotheses in kangaroos, which are ecological analogues of ungulates. Kangaroos exhibit a wide range of body sizes, particularly among mature males, and so the effects of body size and sex can be distinguished. We tested predictions derived from these hypotheses by comparing the distribution of three sex–sex size classes of western grey kangaroos Macropus fuliginosus, in different habitats, and the composition of groups of kangaroos, across seasons. In accordance with the predation risk-reproductive strategy hypothesis, during the non-breeding season, females, which were more susceptible to predation than larger males, and were accompanied by vulnerable young-at-foot, were over-represented in secure habitats. Large males, which were essentially immune to predation, occurred more often than expected in nutrient-rich habitat, and small males, which faced competing demands of predator avoidance and feeding, were intermediate between females and large males in their distribution across habitats. During the breeding season, females continued to be over-represented in secure habitats when their newly emerged pouch young were most vulnerable to predation. All males occupied these same habitats to maximize their chances of securing mates. Consistent with the social hypotheses, groups composed of individuals of the same sex, irrespective of body size, were over-represented in the population during the non-breeding season, while during the breeding season all males sought females so that mixed-sex groups predominated. These results indicate that body size and reproductive strategies are both important, yet independent, factors influencing segregation in western grey kangaroos.

The summer games

As part of a nationally funded project, we have developed and used 'games' as student centred teaching resources to enrich the capacity for design in beginning students in architecture, landscape architecture and urban design. Students are encouraged to learn inter-actively in a milieu characterised by self-directed play in a low-risk computer modelling environment. Recently thirteen upper year design students, six from Adelaide University (Adelaide, South Australia, Australia), five from Deakin University (Geelong, Victoria, Australia), and two from Victoria University, (Wellington, New Zealand) were commissioned over a ten-week period of the 2000-2001 Australian summer to construct a new series of games. This paper discusses the process behind constructing these games.

This paper discusses six topical areas:

– what is a game;
– specific goals of the summer games;
– the structure of a game;
– the game-making process;
– key findings from the production unit; and
– future directions.

RTS and RPGs : New literacies and multiplayer computer games

Technopopular culture such as computer games immerses young people in highly complex and engaging worlds, worlds in which literacy and communicative practices are significantly reconfigured and extended by the contexts in which they occur. This paper reports on a study exploring the textual engagement, pleasures and literacies entailed in playing on line computer games amongst a group of young people aged 15-16. It explores the ways in which these young people read and utilised intersections between traditional print-based text, visual images, symbols, sound, interactivity and other elements to play and make sense of a range of Real Time Strategy and Role Playing Computer Games; the place of games and gaming amongst other text-based leisure activities in their lives; and issues of interpretation, representation and response entailed in playing with real or virtual partners in cyberspace.

An evolutionary computing approach to minimize dynamic hedging error

The objective of our present paper is to derive a computationally efficient genetic pattern learning algorithm to evolutionarily derive the optimal rebalancing weights (i.e. dynamic hedge ratios) to engineer a structured financial product out of a multiasset, best-of option. The stochastic target function is formulated as an expected squared cost of hedging (tracking) error which is assumed to be partly dependent on the governing Markovian process underlying the individual asset returns and partly on
randomness i.e. pure white noise. A simple haploid genetic algorithm is advanced as an alternative numerical scheme, which is deemed to be
computationally more efficient than numerically deriving an explicit solution to the formulated optimization model. An extension to our proposed scheme is suggested by means of adapting the Genetic Algorithm parameters based on fuzzy logic controllers.
