Neoliberalism and the Institutions for Regional Development in Australia

This paper examines some effects of the pursuit of neoliberalism on regional development policy and practice in Australia, and in particular on the activities and effectiveness of regional development organisations. The paper interprets data from a survey of 505 regional development organisations across Australia through the framework of Jessop's contribution to state theory and his identification of four key trends in economic management under neoliberalism. Regional development policies are seen as a response of governments to electoral pressure from regions, but a response that is constrained by the dominance of neoliberal ideology. The objectives of regional development are predominantly economic, but are often limited to the role of facilitation and the provision of information. Some responsibility for regional development has been shifted downwards to regions, but the effectiveness of the organisations given this responsibility is reduced by the short‐term and competitive nature of much of their funding, the lack of coordination between regional development actors at the local level, the proliferation of agencies and the competition between them. The paper concludes that regional development agencies in Australia are in many ways a product of neoliberalism, since they represent one way in which governments can be seen to be responding to regional pressure for assistance but they can do so without incurring significant costs. Yet regional development bodies are also a victim of neoliberalist thinking, since it denies them the resources and the powers they need to be more successful in their work.     

THE ELEMENTAL COMPOSITION OF BENIN MEMORIAL HEADS*

Among the Nigerian cast copper‐alloy artefacts, the chronology of the Benin memorial heads has been the most fully worked out. Therefore, a study focused upon their elemental compositions is particularly likely to be interpretable in terms of development of the alloys used in their making. The elemental analyses, both published and unpublished, of 66 Benin heads, supplemented with seven analyses of some artefacts excavated from a well‐dated, very early Benin site, have been collected, analysed statistically and computed to the elemental analyses of 11 heads and figures from Udo. All but a very few of the Benin heads and artefacts separate into five compositional groups, indicating a chronological sequence of different alloying traditions. All but one of the Udo objects fall into a distinctly separate compositional group, together with two Medicine heads. The compositional groups correlate remarkably well with the stylistic types proposed by Dark.     

The Effects of Climate and Socio‐Demographics on Direct Household Carbon Dioxide Emissions in Australia

Household CO₂ emissions are a significant contributor to global greenhouse gas emissions and consequently climate warming. Despite this, there has been little consideration of how household CO₂ emissions may be affected by changes in climate. The aim of the present study has been to investigate the way climate, as well as socio‐demographic characteristics, may affect household CO₂ emissions produced from energy use. A national online survey was conducted to determine current household CO₂ emissions in Australia as well as capture the ownership and use of household appliances and installations. Electricity and gas‐based emissions as well as the ownership of a variety of household appliances and installations were found to be strongly associated with temperature. Electricity and gas emissions were found to decrease as annual average temperatures increase. However, as temperatures continue to rise under climate change this pattern may be reversed owing to increased reliance on air conditioners. One option for preventing this from occurring is to encourage houses to adopt more solar‐passive installations. Although this may be expensive, households with higher emissions tend to have higher incomes, indicating that they may have the capacity to pay for such installations.     

“The Enchanter's Wand”: Charles Darwin,Foreign Missions,and the Voyage of H.M.S. Beagle*

It often goes unmentioned that one of the primary purposes of the famous circumnavigation of H.M.S. Beagle was foreign missions. Charles Darwin, the voyage's most famous participant, was at best noncommittal about the missionary activity surrounding him for most of the trip. He emerged from the voyage, however, as an enthusiastic and outspoken proponent of missions. The British missions at Tahiti prompted him to change his view. Sailing to Tahiti, he read several accounts about the South Sea missions, and had already begun making arrangements to publish his “Diary” as a travel journal. Darwin became convinced that missionaries helped “advance” the natives toward “civilization” and thereafter enthusiastically defended missionaries in an ongoing public debate.     

MICROZONATION OF THE EXPECTED SEISMIC SITE EFFECTS ACROSS PORT VILA,VANUATU

The city of Port Vila, Vanuatu, is located in one of the most active seismic regions on earth. Earthquakes are felt frequently and, due to very rapid plate convergence rates, return period of large earthquakes (M>6) in the New Hebrides Benioff zone can be less than 10 years. Even though Port Vila does not lie on an identified seismic fault zone, strong motions by nearby earthquakes have to be expected due to the city's geographical location close to the plate boundary of New Hebrides convergence zone. An accurate estimation of the seismic ground motion across the city is of prime importance for urban developments and mitigation of earthquake risk. Following many examples of monitored strong earthquakes in the current century, it is evident that the local site effects may have a dominant contribution to the intensity of damage and destruction. In this study we focussed on the first stage of associating site effects and seismic hazard by preparing a microzonation map for Port Vila. The seismic microzonation of the city has been carried out to provide a detailed map of the zones that exhibit site effects in terms of resonance frequencies and approximated amplification of the ground shaking. Having in mind that these data will be used in improving building design to sustain strong ground motions, our analysis is limited to the frequency band of 1–10 Hz, corresponding to the expected resonance of different types of buildings in Port Vila. The Nakamura technique has been used to estimate site amplification effects from single station noise recordings. Interestingly, excluding one site located on an old dump zone, the amplification factors at about the 100 sites surveyed in Port Vila remain below 3 with an average well below 2 in the 1 to 10 Hz frequency band. These results suggest that there is no significant Vs velocity change in consequently layered material and that the uppermost sedimentary layers in the surveyed down town area are relatively thin. These observations are in agreement with the mapping of limestone terraces throughout Port Vila area. However, both the surface geology and results from seismic zonation indicate a thicker (up to several tens of meters) sedimentary cover around the Bauerfield airport and in the Mele terrace zone. Low resonance frequencies (around and below 1 Hz) and amplification factor of the order of 5 were observed over this large area, immediately outside Port Vila. Any building development in this area should take these results into account.     

The timescale and mechanisms of fault sealing and water‐rock interaction after an earthquake

Hydrogeochemical monitoring of a basalt‐hosted aquifer, which contains Ice Age meteoric water and is situated at 1220 m below sea level in the Tjörnes Fracture Zone, northern Iceland, has been ongoing since July 2002. Based on hydrogeochemical changes following an earthquake of magnitude (M_w) 5.8 on 16 September 2002, we constrained the timescales of post‐seismic fault sealing and water–rock interaction. We interpret that the earthquake ruptured a hydrological barrier, permitting a rapid influx of chemically and isotopically distinct Ice Age meteoric water from a second aquifer. During the two subsequent years, we monitored a chemical and isotopic recovery towards pre‐earthquake aquifer compositions, which we interpret to have been mainly facilitated by fault‐sealing processes. This recovery was interrupted in November 2004 by a second rupturing event, which was probably induced by two minor earthquakes and which reopened the pathway to the second aquifer. We conclude that the timescale of fault sealing was approximately 2 years and that the approach to isotopic equilibrium (from global meteoric water line) was approximately 18% after >10⁴ years.     

THE COMPOSITION OF BRASSES FROM IFE AND BENIN

Brass alloys from Ife are compared with a selection of brasses from Benin. Four sources of mixed zinc and lead ore were used in Ife. In Benin lead and copper from different sources were added to these four alloys, which may represent the melting down of older castings. Comparisons are made with analyses from Europe and other parts of Africa.
