Using the surface profiles of modern ice masses to inform palaeo-glacier reconstructions

Morphometric study of modern ice masses is useful because many reconstructions of glaciers traditionally draw on their shape for guidance Here we analyse data derived from the surface profiles of 200 modern ice masses-valley glaciers icefields ice caps and ice sheets with length scales from 10(0) to 10(3) km-from different parts of the world Four profile attributes are investigated relief span and two parameters C* and C that result from using Nye s (1952) theoretical parabola as a profile descriptor C* and C respectively measure each profile s aspect ratio and steepness and are found to decrease in size and variability with span This dependence quantifies the competing influences of unconstrained spreading behaviour of ice flow and bed topography on the profile shape of ice masses which becomes more parabolic as span Increases (with C* and C tending to low values of 2 5-3 3 m(1/2)) The same data reveal coherent minimum bounds in C* and C for modern ice masses that we develop into two new methods of palaeo glacier reconstruction In the first method glacial limits are known from moraines and the bounds are used to constrain the lowest palaeo ice surface consistent with modern profiles We give an example of applying this method over a three-dimensional glacial landscape in Kamchatka In the second method we test the plausibility of existing reconstructions by comparing their C* and C against the modern minimum bounds Of the 86 published palaeo ice masses that we put to this test 88% are found to be plausible The search for other morphometric constraints will help us formalise glacier reconstructions and reduce their uncertainty and subjectiveness (C) 2010 Elsevier Ltd All rights reserve

Textiles as Material Gestalt: Cloth as a Catalyst in the Co-designing Process

Textiles is the common language within Emotional Fit, a collaborative research project investigating a person-centred, sustainable approach to fashion for an ageing female demographic (55+). Through the co-designing of a collection of research tools, textiles have acted as a material gestalt for exploring our research participants' identities by tracing their embodied knowledge of fashionable dress. The methodology merges Interpretative Phenomenological Analysis, co-design and a simultaneous approach to textile and garment design. Based on an enhanced understanding of our participants textile preferences, particular fabric qualities have catalysed silhouettes, through live draping and geometric pattern cutting to accommodate multiple body shapes and customisation. Printedtextiles have also been digitally crafted in response to the contours of the garment and body and personal narratives of wear. Sensorial and tactile interactions have informed the engineering and scaling of patterns within zero-waste volumes. The article considers the functional and aesthetic role of textiles

Local industrial strategy and skills policy in England: Assessing the linkages and limitations – a case study of the Sheffield City Deal

This paper examines changes in local economic development policy which occurred between 2010 and 2015, with a focus on the relationship between industrial strategy and skills policy. Under the Coalition Government, Local Enterprise Partnerships were established and tasked with facilitating local growth, and to do so many identified a set of (potential) growth sectors for industrial strategy to support. These sectors tended to be drawn from a relatively narrow range of industries which therefore often excluded a large proportion of the local economy. An important focus of the support for growth sectors for many has been through an ambition to influence the local skills system. Skills policy more broadly has been an important dimension of devolution, and a number of City Deals have included elements of skills policy. Echoing previous national policy however, the focus of local concerns with skills under devolution has been framed largely with reference to skills gaps and shortages. While specific skills gaps and shortages can be identified, this paper questions whether this default position is reflected widely, and as such, if a narrow focus on skills supply is a sufficient approach. It is argued that to support local growth across a broad base, greater attention needs to be paid to stimulating employer demand for skills through better integrating industrial and innovation policy with skills policymaking across a wider section of the local economy. To support these arguments we present a case study of the Sheffield City Deal

Inclusive growth in English cities: mainstreamed or sidelined?

<p>The concept of inclusive growth is increasingly presented as offering prospects for more equitable social outcomes. However, inclusive growth is subject to a variety of interpretations and lacks definitional clarity. In England, via devolution, cities are taking on new powers for policy domains that can influence inclusive growth outcomes. This opens up opportunities for innovation to address central issues of low pay and poverty. This paper examines the extent to which inclusive growth concerns form a central or peripheral aspect in this new devolution through the content analysis of devolution agreements. It concludes that inclusive growth concerns appear to be largely sidelined.</p

The realities of being young, unemployed and poor in post-industrial Britain

Poverty is a complex cultural phenomenon that is very much in existence in contemporary post-industrial Britain. A young person’s poverty-striken situation, in addition to their marginalised hierarchal position, shapes their repetitive life cycle comprising different but interrelated forms of marginality. The young people in this ethnographic study were found to experience marginalisation in their education, training and work spheres, as well as in their community, family and home. The purpose of this article is to carefully analyse the link between marginalised young people’s (in)ability to participate in key social systems and their (lack of) access to financial, cultural and social resources

Linking the sectoral employment structure and household poverty in the United Kingdom

Structural changes in the labour markets of developed economies, and changes in their institutional characteristics, have led to growing unease about the nature of low-paid employment. Related concerns have been expressed about the persistence of low-pay, the fragmentation of work and the growth of under-employment. While all these factors have potential implications for individuals’ earnings, less is known about the connection between labour market change, patterns of sectoral growth and decline and household poverty outcomes. This article shows distinct patterns of poverty outcomes by sector of employment, after controlling for other factors. However, household characteristics, in particular the presence of a second earner, do strongly mitigate the poverty risk. Overall, the findings demonstrate that policymakers need to develop a coherent policy towards poverty that recognises the nature of jobs growth and the distribution of ‘good jobs’ across households

Development and validation of a reference marker for identification of aerobic and anaerobic bacteria associated with diabetes chronic wound ulcers using PCR denaturing gradient gel electrophoresis

Introduction: Diabetes chronic wounds consist with a diverse microbial community and unculturablespecies may be highly prevalent.Objectives: This study aimed to establish a bacterial reference marker consisting of a group ofchronic wound related bacteria, using polymerase chain reaction-denaturing gradient gelelectrophoresis (PCR-DGGE) for profiling of bacteria in diabetes chronic wound infections.Methods: DNA was extracted from the known wound bacterial strains. PCR–DGGE was performedusing eubacterial specific primers targeting V2-V3 region of 16S rDNA. DGGE was performed usinga 30-55% denaturing gradient. Migration position of each organism was detected on DGGE gel andimportant organisms were selected. Equal volume from PCR products of each selected organism wasmixed, diluted with gel loading dye in 1:1.5 ratio and used for all DGGE gels. The ladder was thensubjected to species identification of fifteen tissue debridement specimens obtained from diabeteschronic wound ulcers. The identification efficacy was tested by sequencing.Results: DNA of bacterial pathogens which showed different migration distances on the gel werecombined and used as a reference panel. This bacterial ladder consisted of eleven different bacterialspecies including Bacteroides sp., S. aureus, Acineto bacter sp., P. aeruginosa, Streptococcus Group Aand Group B sp., E. faecalis, Providencia sp., Veillonella sp., E .coli and Enterobacter sp. Accordingto the reference panel, Pseudomonas species were abundant. Further the results were confirmed bysequencing.Conclusion: Reference marker allows comparative analysis of DGGE patterns and can be used as atool for presumptive identification of polymicrobial microbiota in chronic wound infections
