INELASTIC SEISMIC RESPONSE ANALYSIS BASED ON ENERGY DENSITY SPECTRA

Energy balance is used to characterise the seismic energy in inelastic structures where energy input to the structure is decomposed into strain energy, kinetic energy, damping energy, and plastic energy. The exact quantification of plastic energy is derived based on force analogy method for moment-resisting frames. A method of generating energy density spectra is then proposed based on yield displacement of a single degree of freedom system. The effects of different structural vibration characteristics are then studied on energy density spectra. These effects include variations of yield displacement level, earth-quake scaling factor, and damping ratio, which proves to be useful in improving the basic understanding of energy characteristics in structural dynamic response. Finally, the use of energy density spectra is demonstrated on a multi-degree of freedom structure to show the practical applications of these spectra.     

Underground drainage at Mole Creek,Tasmania

Complex patterns of groundwater flow exist in the Mole Creek karst area, Tasmania. Many surface drainage divides are breached underground The evolution of the drainage has been dominated by (I) the deflection of streams along the strike of the limestone beds; (2) progressive changes to hydraulic gradients; and (3) a history of climate change during the Quaternary that has seen drainage diverted underground by glaciers and/or by proglacial and periglacial sedimentation     

Multiple Glaciation of the Upper Franklin Valley,Western Tasmania Wilderness World Heritage Area

Part of an extensive ice cap that developed in the Tasmanian Central Highlands during the late Cainozoic discharged southwards into the valley of the Franklin River and its upper tributaries where it merged with smaller glaciers that accumulated behind local snowfences. Glacial landforms and sediments in the now heavily forested valleys indicate that at least three and possibly as many as six glaciations took place. The earliest and most extensive glaciation occurred during the Pliocene or earliest Pleistocene. At this time ice extended at least 27km down the Franklin Valley and covered at least 326km² of the study area. This ice was confluent with glaciers in the West Coast Range to the west and in the Derwent Valley to the east Such confluence offers the possibility of better correlation of glacial events between western Tasmania and the Central Highlands. The smallest and most recent glaciation occurred during the late Last Glacial Stage when the Franklin Glacier did not exceed 12km in length. The glaciers were characterised by high rates of mass throughput and were of temperate maritime type.     

Liberalism and cultural claims in Central and Eastern Europe: toward a pluralist balance†

ABSTRACT. This article relies on cases from new EU member states in postcommunist Europe to integrate two overlapping debates about majority–minority relations. Since the Second World War, political theorists and international institutions have tended to discourage group‐rights approaches in favour of individual rights; meanwhile, policy‐makers who achieved interethnic peace in postcommunist Europe have often opted for group‐rights approaches. On the basis of political theory, international norms and the conduct of political elites in this region, we argue that both the individual‐rights and group‐rights approaches can be differentiated internally along the dimension of pluralism – that is, their willingness to accommodate multiple processes of cultural reproduction. Moreover, both group‐rights and individual‐rights approaches can offer justifications for restricting minority cultural opportunities; furthermore, restrictive group‐rights approaches sometimes cloak their efforts behind ‘Western‐sounding’ individual‐rights rhetoric. Likewise, both group‐rights and individual‐rights approaches can permit group accommodation that can lead to political integration. We find that de facto pluralist approaches to minority accommodation – often spearheaded by moderate parties of the majority in coalition with minority‐group parties – encourage ethnic peace, regardless of their foundation in individual or group rights.     

Theological Innovation from Spiritual Experience: Henry Alline's Anti‐Calvinism in Late Eighteenth‐Century Nova Scotia and New England*

The strident anti‐Calvinism of Nova Scotian revivalist Henry Alline (1748–1784), who left a substantial mark on the religious landscape of Nova Scotia and parts of New England, has been noted but largely neglected by historians. This article investigates Alline's anti‐Calvinism and concludes that it is best explained as arising from his own interpretation of his vivid spiritual experiences, particularly his dramatic conversion. Rather than simply rejecting Calvinist theology in favour of an emotive, experiential religion, however, Alline drew on his experiences to formulate an alternative anti‐Calvinist theology. Alongside other examples from the period, Alline's case suggests that evangelical “democratization” of popular religion in the eighteenth‐century transatlantic revivals could result in theological innovation rather than the abandonment of theology.     

‘Tangled up in Blue’: The Death,Dress and Identity of an Early Viking-Age Female Settler from Ketilsstaðir,Iceland

IN 1938, a woman’s burial was uncovered by road builders at Ketilsstaðir in north-eastern Iceland. Recently, her physical remains and associated funerary goods were re-examined by an international, interdisciplinary team and formed the basis for an exhibition at the National Museum of Iceland in 2015. This paper focuses on the items of dress that accompanied the woman — born in the British Isles, but who migrated to Iceland at a very young age — to gain insights into the ways her cultural identity was expressed at the time of her death. Here we explore the roles played by material culture in signaling her identity, and the technologies and trade networks through which she was connected, visually, to Scandinavia, the British Isles, and the Viking world at large.     

Air Services at Australian Cities: Change and Inertia 2005–2010

This research analyses international and domestic air services in Australia during a six year period, 2005–2010. We place air services into their urban context by relating them to city‐based measures such as population, tourism, and producer services employment among other measures. The research takes a supply‐side approach in an assessment of international and domestic capacity at major Australian airports from the perspective of the number of seats, the nature of links, and competition. Multiple linkage analysis and the concept of effective competitors allow us to explore this perspective at greater depth. Our findings show substantial changes in international patterns, specifically favouring Melbourne, Perth, and Gold Coast. In contrast, the domestic scene is characterised by little change, an outcome we link to the underlying stability in the settlement system and the location of some major economic activities. While the results are related to our measures of urban characteristics, some special region‐specific aspects are also at work. Finally, in both the international and domestic cases we find evidence of greater airline diversity which may benefit consumers.
