Dr. Alexander Tille (1866–1912) was one of the key-figures in Anglo-German intercultural transfer towards the end of the 19th century. As a lecturer in German at Glasgow University he was the first to translate and edit Nietzsche’s work into English. Writers such as W. B. Yeats were influenced by Nietzsche and used Tille’s translations. Tille’s social Darwinist reading of the philosopher’s oeuvre, however, had a narrowing impact on the reception of Nietzsche in the Anglo-Saxon world for decades. Through numerous publications Tille disseminated knowledge about British authors (e.g., Robert Louis Stevenson, William Wordsworth) in Germany and about German authors (e.g., Johann Wolfgang von Goethe) in Britain. His role as mediator also extended into areas such as history, religion, and industry. During the Boer war, however, Tille’s outspoken pro-German nationalism brought him in conflict with his British host society. After being physically attacked by his students he returned to Germany and published a highly anglophobic monograph. Tille personifies the paradox of Anglo-German relations in the pre-war years, which deteriorated despite an increase in intercultural transfer and knowledge about the respective Other.

The study examines the impact of knowledge and social bonds on commitment and behavioural loyalty in auditor-client relationships. A model is proposed and tested using data collected from stock exchange company executives in the UK. The results show the significant effects of the knowledge and social bonds on commitment. Commitment is shown to be a mediating variable, which influences word-of-mouth and continuance but not the purchase of non-audit services. In the light of these findings, suggestions are provided to auditors in developing relationship bonds and managing the relationship at the firm level.

Integrated marine planning, which must take into consideration environmental and social impacts, is being introduced widely in Europe, the USA, Australia and elsewhere. Installation of offshore windfarms creates impacts both on local marine ecosystems and the view of the seascape and is one of multiple activities in the marine area that must be addressed by marine planning. The impacts on people's values (and hence welfare) of changes in ecology and amenity that could arise from the installation of a windfarm in the Irish Sea were assessed using a discrete choice experiment administered through an online survey. The ecological changes investigated were: increased species diversity resulting from artificial reef effects, and the effect of electromagnetic fields from subsea cables on marine life; whilst the amenity change was the visibility of offshore turbines from land. Respondents expressed preferences for ecological improvements but had less clear preferences regarding the height and visibility of the turbines. In particular distance decay effects were observed with respondents further away from the coast being less concerned about visual impact created by offshore turbines. Understanding ecological and amenity impacts and how they are valued by people can support the decisions made within marine planning and licensing.

After considering museums as cultural institutions responsible for preserving cultural memory and its evolution over time, this article describes the cultural practices within our society that are aimed at disseminating art and at reproducing and transmitting culture, history and identity. Further, it considers the key role that older people are steadily assuming in Spain’s ageing society. New social-empowerment activities based on volunteering by the elderly are linked to generativity because the individual and social groups acquire new skills through those activities, thereby strengthening a society for all ages. Never in the history of social work have so many older people been prepared to participate actively at the community level, and never has a social movement with these features gone so unnoticed by so many social agents.

Previous studies revealed that, upon exposure to hypoxia, tumour cells acquire resistance to the cytolytic activity of IL-2-activated lymphocytes. The MHC class I chain-related (MIC) molecules – comprised of MICA and MICB – are ligands for the activating NKG2D receptor on Natural Killer (NK) and CD8+ T cells. MIC-NKG2D interactions lead to the activation of NK and CD8+ T cells and the subsequent lysis of the tumour cells. The study also showed that the mechanism of the hypoxia-mediated immune escape involves the shedding of MIC, specifically MICA, from the tumour cell surface. The objective of the present study was to determine whether the shedding of MICA requires the expression of hypoxia inducible factor-1 (HIF-1), a transcription factor that regulates cellular adaptations to hypoxia. Exposure to hypoxia (0.5% O2 vs. 20% O2) led to the shedding of MIC from the surface of MDA-MB-231 human breast cancer cells and DU-145 human prostate cancer cells as determined by flow cytometry. Knockdown of HIF-1α mRNA using siRNA technology resulted in inhibition of HIF-1α accumulation under hypoxic conditions as determined by Western blot analysis. Parallel study revealed that knockdown of HIF-1α also blocked the shedding of MICA from the surface of MDA-MB-231 cells exposed to hypoxia. These results indicate that HIF-1 is required for the hypoxia-mediated shedding of MICA and, consequently, that HIF-1 may play an important role in tumour immune escape. Ongoing studies aim to determine the HIF-1 target genes involved in the shedding of MICA under hypoxia.
