    A review of Central Asian glaciochemical data

    Get PDF
    The glaciers of central Asia provide suitable locations from which to recover continuous, high-resolution glaciochemical records on a continental scale. Although the glaciochemical investigations undertaken to date in central Asia are few in number and limited in terms of spatial coverage and length of record, some preliminary observations can be made concerning regional and seasonal trends in snow chemistry in this region. The sodium chloride ratio for most snow samples collected in central Asia approaches the ratio found in sea water (0.86 in /Leq kg-I ), reflecting a marine source for these constituents. Sodium and chloride concentrations are, on average, 3-10 times higher in the Himalayas than in the Karakoram, demonstrating the greater influence of monsoonal sources of moisture in the Himalayas. Very high sodium concentrations from Khel Khod Glacier probably reflect a local crustal source from surrounding ice-free areas. Low nitrate concentrations were found in snow collected from the southern margin of the Himalayas and high concentrations in snow deposited on the north margin of the Himalayas. This strong regional trend in the spatial distribution of nitrate suggests the influx of continental aerosols, rich in nitrate, originating from the arid regions of central Asia. High calcium concentrations measured in snow from Mount Everest and the north-west corner of China are also indicative of dust derived from the arid regions of central Asia. Very high sulfate concentrations found in snow from the Tien Shan and the Bogda Shan most likely reflect local anthropogenic sources. The altitude effect on isotopic composition is not apparent from snow samples collected in central Asia. Understanding the processes which control the chemical content of snow, the local-to-regional scale complexities, and the seasonal variability are fundamental steps necessary to assess the potential for recovering representative long-term glaciochemical records from central Asia

    Encountering authority and avoiding trouble: young migrant men’s narratives of negotiation in Europe

    Drawing on data from seven European countries (Czech Republic, Finland, France, Germany, Ireland, Italy and the United Kingdom), this article seeks to identify how young migrant men engage with authority and avoid conflict against a backdrop of increasing hostility towards migrants in many European countries. As this article contends, even those with permanent residency status in the host country often find themselves having to justify their legitimacy to carry out daily tasks, resulting in many young male migrants living with feelings of perpetual insecurity. As such, a number of coping strategies are employed by young migrant men in order to assuage such feelings and mitigate potential risks. Focusing on the lived experiences of this group, as described in narrative interviews, our study found that many young migrant men are required to enter into negotiations with authority figures, where there is a considerable power differential. Acting as risk assessors, they find themselves forced to navigate complex and challenging social relations and support networks. We show how self-limiting behaviour intended to avoid or control interactions with authority and the negotiations conducted to minimize the risk of ‘trouble’ by young migrant men not only are problematic in the context of day-to-day activities but can very often have a detrimental impact on their lives

    The Human Intestinal IgA Response; Burning Questions

    Get PDF
    The title of this special topic invites us to identify areas in the field of IgA biology that are uncertain or in need of clarification. The inductive phase of the human intestinal IgA response has been a controversial area for some years. Therefore, to structure this review, we have identified key questions that are debated in this field. We have provided explanations of the origins of the uncertainties and have provided our own reasoned answers to the questions we pose

    Integrated Virtual Reality for a Motivating and Effectual Language-Learning Experience

    Get PDF
    The increased globalization of STEM fields and the resulting needed multilingualism provide ample reason to infuse language classrooms with responsive and immersive technologies. Furthermore, technology has proven to be a powerful resource to motivate students, regardless of the field. Early results show that the use of immersive technology positively affects both motivation and retention, and that students desire these types of technology and resources in more of their courses

    Foyle Bubbles: How can design reduce suicide attempts using everyday social and civic spaces?

    The River Foyle and its environments, banks and bridges in Derry/Londonderry in Northern Ireland have become associated with poor mental health and emotional wellbeing. ‘Our Future Foyle’ is a collaborative research initiative looking at how health and wellbeing can be designed into the riverfront in the city as a means of suicide prevention. This paper discusses one aspect and output of the research and design process: ‘Foyle Bubbles’ In order to carry out research and engage with the community as a whole the team have been carrying out a series of architectural interventions during city scale events. Using various co-design methods, the project has sought people from across the community, in an area which is known for its past conflict. The research showed the need for shared space along the riverfront. People within the community felt that 'one side of the river gets more than the other side'. This pointed to the need for movable spaces that could respond to the needs of different areas of the waterfront without having to be located in one area. Such spaces could be occupied by a variety of organisations and individuals to create a network and reinforce that community congestion. ‘Foyle Bubbles’ are a series of satellite spaces designed to house arts, commercial, educational and well-being activities around the riverfront; these will act as suicide deterrents and increase footfall and so achieve natural surveillance of the site. These portable pods offer the opportunity for enterprise and community engagement through social and civic functions. This pilot and subsequent measurable data provide the necessary evidence for larger procurement and roll out across the local community and service users with the hope of creating a connected, engaged and positive community on the river with the needs of people in crisis at its heart

    Creating an Inclusive Architectural Intervention as a research Space to Explore Community Wellbeing

    Get PDF
    Abstract: This paper outlines a two-year active design research project coordinated in collaboration with Public Health Northern Ireland and set in the city of Derry/Londonderry to explore how inclusive design methodologies can produce interventions to improve community wellbeing. The research focuses on the waterfront of the River Foyle and how an inclusive architectural intervention challenged the areas’ negative associations. In the last decade, the waterfront has become synonymous with mental health crisis and suicide. This has led to the phrase “I'm ready for the Foyle” becoming embedded within the communities’ language as a colloquial term for stress. This project seeks to extend inclusive design within the community, creating wellbeing spaces around the bridges and banks of the river, with outcomes focused on drawing people to the area as a place of celebration and life affirming activities. The project has helped to develop Inclusive Design as a means of engaging a whole city in the redesign of public spaces for improved wellbeing
