Development of a biocidal treatment regime to inhibit biological growths on cultural heritage: BIODAM

Existing chemical treatments to prevent biological damage to monuments often involve considerable amounts of potentially dangerous and even poisonous biocides. The scientific approach described in this paper aims at a drastic reduction in the concentration of biocide applications by a polyphasic approach of biocides combined with cell permeabilisers, polysaccharide and pigment inhibitors and a photodynamic treatment. A variety of potential agents were screened to determine the most effective combination. Promising compounds were tested under laboratory conditions with cultures of rock deteriorating bacteria, algae, cyanobacteria and fungi. A subsequent field trial involved two sandstone types with natural biofilms. These were treated with multiple combinations of chemicals and exposed to three different climatic conditions. Although treatments proved successful in the laboratory, field trials were inconclusive and further testing will be required to determine the most effective treatment regime. While the most effective combination of chemicals and their application methodology is still being optimised, results to date indicate that this is a promising and effective treatment for the control of a wide variety of potentially damaging organisms colonising stone substrates

Gender, religion, and sociopolitical issues in cross-cultural online education

Cross-cultural education is thought to develop critical consciousness of how unequal distributions of power and privilege affect people’s health. Learners in different sociopolitical settings can join together in developing critical consciousness – awareness of power and privilege dynamics in society – by means of communication technology. The aim of this research was to define strengths and limitations of existing cross-cultural discussions in generating critical consciousness. The setting was the FAIMER international fellowship program for mid-career interdisciplinary health faculty, whose goal is to foster global advancement of health professions education. Fellows take part in participant-led, online, written, task-focused discussions on topics like professionalism, community health, and leadership. We reflexively identified text that brought sociopolitical topics into the online environment during the years 2011 and 2012 and used a discourse analysis toolset to make our content analysis relevant to critical consciousness. While references to participants’ cultures and backgrounds were infrequent, narratives of political-, gender-, religion-, and other culture-related topics did emerge. When participants gave accounts of their experiences and exchanged cross-cultural stories, they were more likely to develop ad hoc networks to support one another in facing those issues than explore issues relating to the development of critical consciousness. We suggest that cross-cultural discussions need to be facilitated actively to transform learners’ frames of reference, create critical consciousness, and develop cultural competence. Further research is needed into how to provide a safe environment for such learning and provide faculty development for the skills needed to facilitate these exchanges.

Finance, social economics and community development

The last three decades have seen social enterprises in the United Kingdom pushed to the forefront of welfare delivery, workfare and area-based regeneration. For critics, this is repositioning the sector around a neoliberal politics that privileges marketization, state roll-back and disciplining community groups to become more self-reliant. Successive governments have developed bespoke products, fiscal instruments and intermediaries to enable and extend the social finance market. Such assemblages are critical to roll-out tactics, but they are also necessary and useful for more reformist understandings of economic alterity. The issue is not social finance itself but how it is used, which inevitably entangles social enterprises in a form of legitimation crises between the need to satisfy financial returns and at the same time keep community interests on board. This paper argues that social finance, how it is used, politically domesticated and achieves re-distributional outcomes is a necessary component of counter-hegemonic strategies. Such assemblages are as important to radical community development as they are to neoliberalism and the analysis concludes by highlighting the need to develop a better understanding of finance, the ethics of its use and tactical compromises in scaling it as an alternative to public and private markets.
