Condition Assessment and Preservation of Open-Air Rock Art Panels During Climate Change

Thousands of Neolithic and Bronze Age open-air rock art panels exist across the countryside in northern England. However, desecration, pollution, and other factors are threatening the survival of these iconic stone monuments. Evidence suggest that rates of panel deterioration may be increasing, although it is not clear whether this is due to local factors or wider environmental influences accelerated by environmental change. To examine this question, 18 rock art panels with varied art motifs were studied at two major panel locations at Lordenshaw and Weetwood Moor in Northumberland. A condition assessment
tool was used to first quantify the level of deterioration of each panel (called “staging”). Stage estimates then were compared statistically with 27 geochemical and physical descriptors of local environments, such as soil moisture, salinity, pH, lichen coverage, soil anions and cation levels, and panel orientation, slope, and standing height. In parallel, climate modelling was performed using UKCP09 to assess how projected climatic conditions (to 2099) might affect the environmental descriptors most correlated with elevated stone deterioration. Only two descriptors significantly correlated (P < 0.05) with increased stage: the standing height of the panel and the exchangeable cation content of the local soils, although moisture conditions also were potentially influential at some panels. Climate modelling predicts warming temperatures, more seasonally variable precipitation, and increased wind speeds, which hint stone deterioration could accelerate in the future due to increased physiochemical weathering. We recommend key panels be targeted for immediate management intervention, focusing on reducing wind exposures, improving site drainage, and potentially immobilizing soil salts.

Laser-driven acceleration of ions:State of the art, perspectives and applications

The acceleration of ions with high-power lasers has been a very active field of research during the past 10 years. This paper summarizes the main results obtained in the field, detailing the mechanisms of the acceleration process and the main observed beam characteristics. Perspectives for future development of the field and current and future applications are also discussed. © 2012 by Società Italiana di Fisica.

Environmental Aspects of Underground Construction and Exploration of Underground Structure – State of the Art

An underground work (such as a tunnel or a cavern) has many, well known, environmental qualities such as: no physical barriers crossing the land, less maintenance costs than an analogous surface structure, less expenses for heating and conditioning; a localized emission of noise, gas, dust during operation and, finally, a better protection against seismic actions.
It cannot be forgotten, anyway, that some negative environmental features are present such as, for example, : perturbation, pollution and drainage of the groundwater; settlements; disposal of waste rock.
In the paper the above mentioned concepts are discussed and analysed to give a global overview of all this aspects.

Protecting the most vulnerable in an economic crisis: a participatory study of civil society organisations in the Republic of Ireland

This paper advances knowledge of how civil society organisations (CSOs) negotiate the shift from boom-time public expenditure to governmental austerity. The study focuses on the Republic of Ireland, where CSOs occupied an important role in providing a voice for ‘vulnerable’citizens in corporatism for over a decade. The global financial crisis and subsequent austerity measures caused the country’s model of corporatist-style ‘social partnership’ to collapse. The article connects CSOs’ adaptation to austerity measures when protecting the ‘people behind the cuts’ to broader questions about co-optation of civil society through state-led policymaking
institutions.

Participatory Action Research with and within community activist groups: capturing the collective experience of Ireland's Community and Voluntary Pillar

The inclusion of community activists in policy planning is increasingly recognized at the highest international level. This article shows how the use of Participatory Action Research (PAR) can present a deeper and more holistic picture of the experiences of Civil Society Organizations (CSOs) in shaping national-level social policy. By utilizing action-based research, the Community and Voluntary Pillar (CVP) of Ireland’s system of social partnership is shown to be an important agent in deliberating national bargaining outcomes (known as the Towards 2016 national agreement). The key contribution of this research is the reflective methodological considerations in terms of PAR design, execution and participant integration in the research process as a way to enrich and develop a deeper and more informed community of practice.

Laser-driven ion acceleration: State of the art and emerging mechanisms

Ion acceleration driven by high intensity laser pulses is attracting an impressive and steadily increasing research effort. Experiments over the past 10-15 years have demonstrated, over a wide range of laser and target parameters, the generation of multi-MeV proton and ion beams with unique properties, which have stimulated interest in a number of innovative applications. While most of this work has been based on sheath acceleration processes, where space-charge fields are established by relativistic electrons at surfaces of the irradiated target, a number of novel mechanisms has been the focus of recent theoretical and experimental activities. This paper will provide a brief review of the state of the art in the field of laser-driven ion acceleration, with particular attention to recent developments.

The Art of Refusal: The Experiences of Grant Makers and Grant Seekers

This research project explores the communications’ experiences and practices of
selected grant making and grant seeking organisations, at the point of grant refusal. It was funded by the Charities Aid Foundation, and undertaken through collaboration with the Association of Charitable Foundations (ACF).
The research context is the enhanced competition for funding in which many grant seeking organisations experience the disappointment of refusal; whilst grant makers also face multiple pressures, in responding to grant seekers’ needs. This is an operating environment in which subsequent organisational learning appears demanding.
The aims of the research were to:
- Increase understanding of the communications demands, challenges and
opportunities in giving, receiving and sharing news of grant refusal
- Identify opportunities for organisational learning in these situations, for grant
makers and grant seekers
- Contribute to future practice improvement and development, by drawing on
the reported experiences and practices of participating respondents.

The research focuses on private, formal grant makers (foundations and trusts); and their grant seeking organisational constituencies. It excludes study of public grant makers’ grant refusal processes and those of individuals making personal gifts, direct businesses’ grant making, and grant making by community foundations and by other operating and fundraising charities. A staged research process began in 2008, and field research completed in 2009/2011.

Empowering Art: Reconfiguring narratives of trauma and hope in the Australian national imaginary

Aboriginal art has been the source of much contention between art curators, gallery owners, art critics and Aboriginal artists themselves. Early aesthetic debates about whether so-called traditional works should be considered ethnographic or artistic have led, at times, to conflicts over the rights of Aboriginal people to have their works exhibited according to the criteria applied to other kinds of Western artworks. This article explores how the dilemmas of troubled ethno-histories are critically embodied and reconfigured in texture and colour. It considers the problems that silenced histories pose for those responsible for their display to the public. As Aboriginal images often conceal troubled intercultural encounters it asks how artworks can be used to provide a counter-polemic to national rhetoric as artists seek to reshape and improve intergenerational futures. This text is published as a counterpart to the contribution to Disturbing Pasts from the artist Heather Kamarra Shearer.
