The national mapping of teacher professional learning project : a multi-dimensional space?

This essay focuses on the National Mapping of Teacher Professional Learning (2008), a report that we co-authored along with a number of other researchers on the basis of extensive surveys and interviews relating to the policies and practices of teacher professional learning in Australia. The report is an update of an earlier survey conducted by David McRae and others, entitled PD 2000, and it registers significant changes in attitudes and practices relating to professional learning across Australia in the intervening period. Perhaps the most significant development is the way professional learning is now recognized as an important vehicle for education reform by systems, schools and by teachers themselves, most notably the standards-based reforms that have such a decisive effect on the policy landscape here in Australia and in other countries. The work of the AATE in developing the Standards for Teachers of English Language and Literacy (STELLA) is mentioned in the report. It was acknowledged that STELLA provides a generative framework for professional learning, sometimes in contradiction to more managerial approaches. The question remains, however, of how English teachers as a professional community might locate themselves within the policy landscape described in this report. This essay is an attempt to promote this kind of discussion and to argue the distinctive nature of the standpoint that English teachers might bring to thinking about and planning for professional learning and practitioner inquiry.

The National Museum of Scotland : a symbol for a new Scotland?

The National Museum of Scotland (forthwith 'Museum') opened to critical acclaim on St Andrew's Day 1998 (see McKean 2000). The timing of the opening was culturally and politically symbolic, taking place on the patron saint of Scotland's day, whilst falling between the devolution referendum for, and the opening of, the reinstated Scottish Parliament. The museum offers a representation of Scotland, one which is negotiated by its creators and visitors alike. Given that national identity is a slippery concept subject to fluidity and change (Hall 1992), the image of stability and authority of a museum, which has been compared to the reification of a church (Horne 1984), offers us an interesting site for developing our understanding of how national identity is constructed.

Insect based navigation and its applications to the autonomous control of mobile robots

Giving robots the ability to autonomously move around in various real-world environments has been a major goal of AI (artificial intelligence) for quite some time. To this end it is vital for robots to be able to perceive their surroundings in 3D; they must be able to estimate the range of obstacles in their path.

Animals navigate through various uncontrolled environments with seemingly little effort. Flying insects, especially, are quite adept at manoeuvring in complex, unpredictable and possibly hostile and hazardous environments.

In this paper it is shown that very simple motion cues, inspired by the visual navigation of flying insects, can be used to provide a mobile robot with the ability to successfully traverse a corridor environment. Equipping an autonomous mobile robot with the ability to successfully navigate real-word environments (in real-time) constitutes a major challenge for AI and robotics. It is in this area that insect based navigation has something to offer.

Competition and cooperation between international courts: a critical approach to the new paradigms of cross-border dispute resolution model

This article examines the arising cross-border dispute resolution models (Cooperation and Competition among national Courts) from a critical perspective. Although they have been conceived to surpass the ordinary solution of a Modern paradigm (exclusive jurisdiction, choice of court, lis pendens, forum non conveniens, among others), they are insufficient to deal with problems raised with present globalization, as they do not abandon aspects of that paradigm, namely, (i) statebased Law; and (ii) standardization of cultural issues.

Thermodynamic properties applied to the sorption isotherms of kiwifruit

The net isosteric heat and entropy of water sorption were calculated for kiwifruit, based on sorption isotherms obtained by the static gravimetric method at different temperatures (20 to 70 degreesC). The Guggenheim-Anderson-deBoer equation was fitted to the experimental data, using direct non-linear regression analysis; the agreement between experimental and calculated values was satisfactory. The net isosteric heat of sorption was estimated from equilibrium sorption data, using the Clausius-Clapeyron equation. Isosteric heats of sorption were found to increase with increasing temperature and could be well adjusted by an exponential relationship. The enthalpy-entropy compensation theory was applied to sorption isotherms and plots of DeltaH versus DeltaS provided the isokinetic temperature, T-B = 450.9 +/- 7.7 K, indicating an enthalpy-controlled desorption process over the whole range of moisture content considered.

Thermal structure, heat content and stability of two lakes in The National Park of Rio Doce Valley (Minas Gerais, Brazil)

The thermal structure, heat content and stability were studied in Lakes Dom Helvécio and Carioca during an annual cycle. It was found that the maximum heat content, stability and work of the wind in Lake Dom Helvécio correspond to two, four and four times, respectively, the values for the Lake Carioca. These difference can be attributed to morphometric differences in the lakes. A long-term record of heat content and stability for lake Carioca is also presented. Diel variations were studied in summer and winter. The tropicality of the lakes is discussed and compared with other lacustrine systems. © 1989 Kluwer Academic Publishers.
