In its totality, the “Long Second World War”—extending from the beginning of the Spanish Civil War to the end of hostilities in 1945—has exerted enormous influence over European culture. Bringing together leading historians, sociologists, and literary and film scholars, this broadly interdisciplinary volume investigates Europeans’ individual and collective memories and the ways in which they have shaped the continent’s cultural heritage. Focusing on the major combatant nations—Spain, Britain, France, Italy, Germany, Poland, and Russia—it offers thoroughly contextualized explorations of novels, memoirs, films, and a host of other cultural forms to illuminate European public memory.

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

Cystic Fibrosis (CF) is a genetic disease featuring a chronic cycle of inflammation and infection in the airways of sufferers. Mutations lead to altered ion transport, which in turn causes dehydrated airways and reduced mucociliary clearance which predisposes the patient to infection, resulting in a severe immune response and tissue destruction (1). Airway dehydration is primarily caused by the hyperabsorption of sodium by the epithelial sodium channel (ENaC) (2). ENaC is activated by the action of a number of predominantly trypsin-like Channel Activating Proteases (CAPs) including prostasin, matriptase and furin (3). Additional proteases known to activate ENaC include human airway trypsin (3), plasmin, neutrophil elastase and chymotrypsin (4).

Activity profiling is a valuable technique which involves the use of small inhibitory molecules called Activity-Based Probes (ABPs) which can be used to covalently label the active site of proteases and provide a range of information regarding its structure, catalytic mechanism, location and function within biological systems. The development of novel ABPs for CAPs, would enhance understanding of the role of these proteases in CF airways disease and in particular their role in ENaC activation and airway dehydration. This project investigates the application of a range of novel broad-spectrum ABPs targeting the various subclasses of serine proteases, to include those proteases involved in ENaC activation. Additionally, the application of more selective ABPs in detecting specific serine proteases is investigated.

Compounds were synthesised by Solid-Phase Peptide Synthesis (SPPS) using a standard Fmoc/tBu strategy. Kinetic evaluation of synthesised ABPs against various serine proteases was determined by fluorogenic steady-state enzyme assays. Furthermore, application of ABPs and confirmation of irreversible nature of the compounds was carried out through SDS-PAGE and electroblotting techniques.

Synthesised compounds showed potent irreversible inhibition of serine proteases within their respective targeting class (NAP855 vs Trypsin k3/Ki = 2.60 x 106 M-1 min-1, NFP849 vs Chymotrypsin k3/Ki = 1.28 x 106 M-1 min-1 and NVP800 vs Neutrophil Elastase k3/Ki = 6.41 x 104 M-1 min-1). Furthermore ABPs showed little to no cross-reactivity between classes and so display selectivity between classes. The irreversible nature of compounds was further demonstrated through labelling of proteases, followed by separation and detection via SDS-PAGE and electroblotting techniques. Targeted labelling of active proteases only, was demonstrated by failure of ABPs to detect previously inactivated proteases. Extension of the substrate recognition site within probes resulted in an increased potency and selectivity in the detection of the target proteases. Successful detection of neutrophil elastase from CF sputum samples by NVP800, demonstrated the application of compounds within biological samples and their potential use in identifying further proteases involved in ENaC activation and airway dehydration in CF patients.

This chapter explores the relationship between cultural policy and arts management. A connection between policy and practice is visible through initiatives within specific localities, nations and at an international scale. Yet, there is little scholarship that develops our understanding of how these two areas interact, how ideas are exchanged and implemented, and where the power is located within this relationship. The approach to arts and cultural management in the UK has a history of professionalization that has developed increasing influence internationally. As a result, this chapter takes the UK as a case study and presents new empirical work to examine how educators and individuals practicing in both fields perceive the relationship of policymaking to the work of management.

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.
