Civil Society Aid to Post-Communist Countries

A major debate within foreign aid literature is whether civil society can be ‘purchased’ through outside assistance.We test this proposition by exploring the influence of aid provided by the United States Agency for International
Development on post-communist civil rights environments. A review of research critical of international assistance highlights the risk of unsustainability, polarization and dependence among recipient civic organizations.We argue that
a more effective stimulant is socio-economic growth, which stimulates committed constituencies, higher citizen expectations and pressure on the state to protect civil freedoms. Using cross-sectional, time-series data from 27
post-communist countries, we find no evidence that aid independently promotes stronger civil rights environments but that economic growth produces substantial improvements. Further, any aid effectiveness appears to be conditional on economic strength.We conclude that developmental organizations should reassess how and where civil society aid is targeted.

Spitzer Space Telescope spectra of post-AGB stars in the large magellanic Cloud-polycyclic aromatic hydrocarbons at low metallicities

This paper reports variations of polycyclic aromatic hydrocarbons (PAHs) features that were found in Spitzer Space Telescope spectra of carbon-rich post-asymptotic giant branch (post-AGB) stars in the Large Magellanic Cloud (LMC). The paper consists of two parts. The first part describes our Spitzer spectral observing programme of 24 stars including post-AGB candidates. The latter half of this paper presents the analysis of PAH features in 20 carbon-rich post-AGB stars in the LMC, assembled from the Spitzer archive as well as from our own programme.We found that five post-AGB stars showed a broad feature with a peak at 7.7 μm, that had not been classified before. Further, the 10-13 μm PAH spectra were classified into four classes, one of which has three broad peaks at 11.3, 12.3 and 13.3 μm rather than two distinct sharp peaks at 11.3 and 12.7 μm, as commonly found in HII regions. Our studies suggest that PAHs are gradually processed while the central stars evolve from post-AGB phase to planetary nebulae, changing their composition before PAHs are incorporated into the interstellar medium. Although some metallicity dependence of PAH spectra exists, the evolutionary state of an object is more significant than its metallicity in determining the spectral characteristics of PAHs for LMC and Galactic post-AGB stars. © 2014 The Authors Published by Oxford University Press on behalf of the Royal Astronomical Society.

Possibilities for change? Diversity in Post-Conflict Belfast

Belfast is often presented as an exemplary divided or post-conflict city. However, this focus can be limiting and an exploration of alternative narratives for Belfast is needed. This paper investigates the diversification of post-conflict Belfast in light of the substantial migration which has occurred in the last decade, outlining the complexities of an emerging narrative of diversity. We note discrepancies in how racial equality is dealt with at an institutional level and report on the unevenness of migrant geographies, issues which require future consideration. We also raise questions that problematize the easy assumption that cultural diversity ameliorates existing sectarian divisions.

Mundane Mobilities in ‘Post-Socialist’ Sofia: Making Urban Borders Visible

This article reflects on an on-going research project which aims to expand the understanding of the production and transformation of urban borders in the Eastern European cities of the ex ‘communist bloc’, starting from the case of Sofia. It explores the proposition that there has been a prolific process of wall making in this city associated with ‘vanishing public spaces’, ‘rescaling of enclosure’, and ‘corrosion of the collective urban realm’ (Hirt, 2012). The paper seeks to understand the social and political effects of this process by delving into the sensorial, emotional and embodied experiences associated with the mundane mobilities of urban residents. Using participants’ self-directed photography and videos from ‘walk-along’ interviews it explores the ways in which borders are made visible and are produced, challenged or resisted through mobility, and delves into the associated senses of deepening social and spatial differentiation in the city.

Post-tensioning of glulam timber with steel tendons

This paper describes a series of four-point bending tests that were conducted, under service loads and to failure, on unreinforced, reinforced and post-tensioned glulam timber beams, where the reinforcing tendon used was 12 mm diameter toughened steel bar. The research was designed to evaluate the benefits offered by including an active reinforcement in contrast to the passive reinforcement typically used within timber strengthening works, in addition to establishing the effect that bonding the reinforcing tendon has on the materials performance.

The laboratory investigations established that the flexural strength and stiffness increased for both the reinforced and post-tensioned timbers compared to the unreinforced beams. The flexural strength of the reinforced timber increased by 29.4%, while the stiffness increased by 28.1%. Timber that was post-tensioned with an unbonded steel tendon showed a flexural strength increase of 17.6% and an increase in stiffness of 8.1%. Post-tensioned beams with a bonded steel tendon showed increases in flexural strength and stiffness of 40.1% and 30% respectively.

Post-tensioning glulam timber beams with basalt FRP tendons

Improvements in the structural performance of glulam timber beams by the inclusion of reinforcing materials can increase both the service performance and ultimate capacity. This paper describes a series of four-point bending tests conducted, under service loads and to failure, on unreinforced, reinforced and post-tensioned glulam timber beams, where the reinforcing tendon used is 12 mm dia. basalt fibre-reinforced polymer. The research is designed to evaluate the benefits offered by including an active reinforcement in contrast to the passive reinforcement typically used within timber strengthening works, in addition to establishing the effect that bonding the reinforcing tendon has on the material's performance. Further experimental tests have also been developed to investigate the long-term implications of this research, with emphasis placed upon creep and loss of post-tensioning; however, this is ongoing and is not presented in this paper. The laboratory investigations establish that the flexural strength and stiffness increase for both the unbonded and bonded post-tensioned timbers compared to the unreinforced and reinforced beams. Timber that is post-tensioned with an unbonded basalt fibre-reinforced polymer tendon shows a flexural strength increase of 2ṡ8% and an increase in stiffness of 8ṡ7%. Post-tensioned beams with a bonded basalt fibre-reinforced polymer tendon show increases in flexural strength and stiffness of 15ṡ4% and 11ṡ5% respectively.

POST-TENSIONING OF TIMBER BEAMS WITH BASALT FIBRE REINFORCED POLYMER

Improvements in the structural performance of glulam timber beams by the inclusion of reinforcing materials can improve both the service performance and ultimate capacity. In recent years research focusing on the addition of fibre reinforced polymers to strengthen members has yielded positive results. However, the FRP material is still a relatively expensive material and its full potential has not been realised in combination with structural timber. This paper describes a series of four-point bending tests that were conducted, under service and ultimate loads, on post-tensioned glulam timber beams where the reinforcing tendon used was 12 mm diameter Basalt Fibre Reinforced Polymer (BFRP). The research was designed to evaluate the additional benefits of including an active type of reinforcement, by post-tensioning the BFRP tendon, as opposed to the passive approach of simply reinforcing the timber beam.
From the laboratory investigations, it was established that there was a 16% increase in load carrying capacity, in addition to a 14% reduction in deflection under service loads when members containing the post-tensioned BFRP composite are compared with control timber specimens. Additionally a more favourable ductile failure mode was witnessed compared to the brittle failure of an unreinforced timber beam. The results support the assumption that by initially stressing the embedded FRP tendon the structural benefits experienced by the timber member increase in a number of ways, indicating that there is significant scope for this approach in practical applications.

Development of Novel Post-Tensioned Glulam Timber Composites

Building Trust in a Post-Conflict Society: An Integrative Model of Intergroup Contact and Intergroup Emotions.

Across one longitudinal and two cross-sectional surveys in Northern Ireland, we tested a model of intergroup relations in which out-group attitudes and behavioral tendencies are predicted by cross-group friendship and positive intergroup appraisals, mediated by intergroup emotions and out-group trust. In study 1, out-group friendship at time 1 predicted out-group trust at time 2 (one year later), controlling for prior out-group trust. In study 2, positive and negative intergroup emotions mediated the effects of friendship on positive and negative behavioral tendencies and attitudes. In study 3, a confirmatory factor analysis indicated that trust and emotions are distinct constructs with unique predictive contributions. We then tested a model in which cross-group friendship predicted intergroup emotions and trust through intimate self-disclosure in out-group friendships. Our findings support an integration of an intergroup emotions framework with research highlighting the importance of cross-group friendship in fostering positive intergroup outcomes.

Out of the Shadows: A one day investigation of the politics of architecture explored through the lens of post-conflict, Belfast

This booklet covers the itinerary and some of the findings of a day-long visit to Belfast on the 7th November 2014 by Peter Oborn; Vice President International of the Royal Institute of British Architects. His visit was in response to a motion submitted to the RIBA council (19.05.2014) calling for the suspension of the Israeli Association of United Architects from the International Union of Architects. Despite members of council speaking against the motion it was carried; 23 members voting for, 16 against, and 10 abstentions. Subsequently the RIBA came under considerable pressure to consider its position in such critical contexts. This visit to Belfast was part of a wider fact-finding mission and evidence taking. At its heart was the question: 'Is it appropriate for the institute (RIBA) to engage with communities facing civil conflict and/or natural disaster and, if so, how it can do so most effectively.' The visit was facilitated by Ruth Morrow, Professor of Architecture, School of Planning, Architecture & Civil Engineering, Queen's University Belfast, and Martin Hare, Royal Society of Ulster Architects (RSUA) president.

Cantilever steel post damaged by wind

An analysis for the cause of fracture failure of a cantilever steel sign post damaged by wind has been carried out. An unusual cause of failure has been identified, which is the subject of this paper. Microscopy and microanalysis of the fracture surface showed that the failure was due to pre-existing cracks, from the fabrication of the post. This conclusion was reached after detecting and analysing a galvanised layer on the fracture surfaces.
