Protracted Peace processes: Policy (Un)learning and the Cyprus Debacle

The article examines why a comprehensive settlement to resolve the Cyprus problem has yet to be reached despite the existence of a positive incentive structure and the proactive involvement of regional and international organizations, including the European Union and the United Nations. To address this question, evidence from critical turning points in foreign policy decision-making in Turkey, Greece and the two communities in Cyprus is drawn on. The role of hegemonic political discourses is emphasized, and it is argued that the latter have prevented an accurate evaluation of incentives that could have set the stage for a constructive settlement. However, despite the political debacle in the Cypriot negotiations, success stories have emerged, such as the reactivation of the Committee for Missing Persons (CMP), a defunct body for almost 25 years, to become the most successful bi-communal project following Cyprus’s EU accession. Contradictory evidence in the Cypriot peace process is evaluated and policy lessons to be learned from the CMP ‘success story’ are identified.

The use of an instrumented vehicle in a wavelet based damage detection approach for bridge structures

Periodic monitoring of structures such as bridges is necessary as their condition can deteriorate due to environmental conditions and ageing, causing the bridge to become unsafe. This monitoring - so called Structural Health Monitoring (SHM) - can give an early warning if a bridge becomes unsafe. This paper investigates an alternative wavelet-based approach for the monitoring of bridge structures which consists of the use of a vehicle fitted with accelerometers on its axles. A simplified vehicle-bridge interaction model is used in theoretical simulations to examine the effectiveness of the approach in detecting damage in the bridge. The accelerations of the vehicle are processed using a continuous wavelet transform, allowing a time-frequency analysis to be performed. This enables the identification of both the existence and location of damage from the vehicle response. Based on this analysis, a damage index is established. A parametric study is carried out to investigate the effect of parameters such as the bridge span length, vehicle speed, vehicle mass, damage level, signal noise level and road surface roughness on the accuracy of results. In addition, a laboratory experiment is carried out to validate the results of the theoretical analysis and assess the ability of the approach to detect changes in the bridge response.

Visualising Invisible Networks as Collaborative Arts Practice

This paper examines approaches to the visualisation of ‘invisible’ communications networks. It situates network visualisation as a critical design exercise, and explores how community artists might use such a practice to develop telematic art projects – works that use communications networks as their medium. The paper’s hypotheses are grounded in the Australian community media arts field, but could be applied to other collaborative contexts.
