Modelling and Seismic Response Analysis of Italian Code-Conforming Base-Isolated Buildings

ABSTRACT

This paper reports on results of nonlinear analyses performed within the RINTC project on an RC building isolated with different systems (High Damping Rubber Bearings, High Damping Rubber Bearings and Flat Sliding Bearings, Friction Pendulum System) and designed according to the Italian design code. The seismic response has been evaluated under different seismic input levels of two sites with different hazard and by considering two Limit States: Global Collapse and Usability-Preventing Damage. The influence of seismic stoppers and modelling uncertainties is also evaluated. Results permit to compute the implicit collapse risk and to identify critical aspects of current design procedures.     

A Narrative Approach to Europe’s Identity Crisis

Alongside the institutionally constructed European identity, research shows that insights into citizens’ sense of belonging are valuable as well in assessing questions of identity. The tendency to conflate European identity with EU identity has spurred debates about the components that underlie European identification. The online subsidiarity adopted by the EU through e-platforms has allowed for a new form of citizenship where e-citizens (de)legitimate the issues under debate. This article examines the contents of European and national identities in the e-debaters’ comments posted on the Debating Europe platform. Drawing on narrative and discursive approaches, we propose a framework to operationalize the (de)legitimation and identification categories used by e-debaters within their discursive construction of European identity. The qualitative empirical research shows three main (de)legitimation clusters: the “EU as a loss,” “inclusive gain,” and “exclusive gain.” We discuss these findings within the broader context of Europeanization, identity multiplicity, and the conditions of the EU enlargement policy.     

From the interpersonal to the internet: social service digitisation and the implications for vulnerable individuals and communities

In Australia, e-government is continuously re-defining service boundaries. While this may be good in the case of transactional interactions, for example the online submission of tax returns, it is less clear that interpersonal services, such as working closely with the long-term unemployed, are best delivered digitally. We consider the impact of social services digitisation on vulnerable communities drawing on an analysis of remote Aboriginal communities. Digital uptake affords great opportunities, but it also carries risks. Some communities have no digital infrastructure and in certain cases traditional face-to-face services have been curtailed, leaving those not online with reduced assistance. We find that concerns about the ‘digital divide’ are well founded. Problems generated by e-government flow across boundaries and appear left to the third sector to resolve with the state playing an even more diminished role in the lives of disadvantaged citizens.     

Governance,public policy and boundary-making

This symposium draws attention to innovative and emerging research in Australian public policy exploring the interplay of governance, public policy and boundary-making. Conceptually and substantively, boundaries are fundamental to understanding policy outcomes, yet remain overlooked and undertheorised. We aim to contribute to public policy debates, in Australia and beyond, by provoking further reflection on this theme, in particular, the distributive effects of boundaries in policy-making; the blurring of boundaries implicit to governance frameworks; the crossing of boundaries, especially by policy-officials within and between institutions; the construction of boundaries to separate and marginalise; and the existence of temporal–spatial boundaries that demarcate jurisdiction and authority. In short, the study of governance and public policy-making is marked by multiple different types of boundaries but the way in which boundaries get drawn and redrawn is also suffuse with political contestation meaning they raise crucial questions about the exercise of power.     

The Influence of Dowel-Bearing Strength in Designing Timber Pegged Timber Joints

ABSTRACT

The employment of timber pegs in timber structure joints is a widespread technology in the field of timber frame building in the United States, where the Timber Frame Engineering Council has published a special Standard to supplement the National Design Specification for Wood Construction. The authors have been studying the possibility of supplementing the Eurocode 5 design formulas, thought for timber joints with metal connectors, with specifications needed for a reliable design when employing timber pegs. The field of application envisaged is that of restoring timber structures and results obtained until now are quite encouraging. In this step of the research, more attention has been paid to deformation process: fir and chestnut samples have been tested to determine their dowel-bearing behavior with steel and ash timber peg while double-shear plane joints made of the same wood species, and fastened with steel as well as timber pegs, have been analyzed.     

The Post-Colonial Constitutional Order of the Commonwealth Caribbean: The Endurance of the Crown and the Judicial Committee of the Privy Council

ABSTRACT

Amongst Britain's former colonies the independent countries of the Commonwealth Caribbean represent something of an anomaly in so far as the majority of them remain constitutional monarchies and continue to retain the Judicial Committee of the Privy Council (JCPC) as their final appellate court, even though the region has had its own final appellate court – the Caribbean Court of Justice – since 2006. This is in marked contrast to Britain's former colonies in Africa and South Asia, the majority of which switched to republicanism soon after independence and at the same time abolished rights of appeal to the JCPC. This paper seeks to uncover the reasons for this anomaly by examining how the path that led to independence was shaped by a particular conception of Dominion status and by the willingness of nationalist leaders to embrace a dual identity: equal parts West Indian nationalist and Empire loyalist. It will also examine the phenomenon of the ‘postcolony’; being the persistence of the colonial order following the acquisition of constitutional independence. The paper has three aims. Firstly, to contribute to a better understanding of the impact of Dominion status and all that it symbolised in a region which is often overlooked in the scholarly literature on this topic. Secondly, better to understand the competing political forces that led three countries in the region to adopt republicanism, but inhibited its adoption elsewhere in the region. Thirdly, and finally, to enhance discussion of the complex nexus between republicanism and the abolition of rights of appeal to the JCPC where political and juridical considerations do not neatly align.
