Is Longer-Distance Migration Slowing? An Analysis of the Annual Record for England and Wales since the 1970s

This paper is prompted by the widespread acceptance that the rates of inter-county and inter-state migration have been falling in the USA and sets itself the task of examining whether this decline in migration intensities is also the case in the UK. It uses annual inter-area migration matrices available for England and Wales since the 1970s by broad age group. The main methodological challenge, arising from changes in the geography of health areas for which the inter-area flows are given, is addressed by adopting the lowest common denominator of 80 areas. Care is also taken to allow for the effect of economic cycles in producing short-term fluctuations on migration rates and to isolate the effect of a sharp rise in rates for 16-24 year olds in the 1990s, which is presumed to be related to the expansion of higher education. The findings suggest that, unlike for the USA, there has not been a substantial decline in the intensity of internal migration between the first two decades of the study period and the second two. If there has been any major decline in the intensity of address changing in England and Wales, it can only be for the within-area moves that this time series does not cover. This latter possibility is examined in a companion paper using a very different data set (Champion and Shuttleworth, 2016).

Are People Changing Address Less? An Analysis of Migration within England and Wales, 1971–2011, by Distance of Move

Expectations of migration and mobility steadily increasing in the longer term, which have a long currency in migration theory and related social science, are at odds with the latest US research showing a marked decline in internal migration rates. This paper reports the results of research that investigates whether England and Wales have experienced any similar change in recent decades. Using the Office for National Statistics Longitudinal Study (ONS-LS) of linked census records, it examines the evidence provided by its 10-year migration indicator, with particular attention to a comparison of the first and latest decades available, 1971-1981 and 2001-2011. This suggests that, as in the USA, there has been a marked reduction in the level of shorter-distance (less than 10km) moving that has involved almost all types of people. In contrast to this and to US experience, however, the propensity of people to make longer-distance address changes between decennial censuses has declined much less, largely corroborating the results of a companion study tracking the annual trend in rates of between-area migration since the 1970s (Champion and Shuttleworth, 2016).

Integration of numerical models in geographic databases: the case of Sado estuary management

Geographic information systems (GIS) are now widely applied in coastal resource management. Their ability to organise and interface information from a large range of public and private data sources, and their ability to combine this information, using management criteria, to develop a comprehensive picture of the system explains the success of GIS in this area. The use of numerical models as a tool to improve coastal management is also widespread. Less usual is a GIS-based management to ol implementing a comprehensive management model and integrating a numerical modelling system into itself. In this paper such a methodology is proposed. A GIS-based management tool based on the DPSIR model is presented. An overview of the MOHID numerical modelling system is given and the method of integrating this model in the management tool is described. This system is applied to the Sado Estuary (Portugal). Some preliminary results of the integration are presented, demonstrating the capabilities of the management system.

Effect of CDC25 and WEE1 on Plant Cell Cycle and Morphogenesis

The cell cycle comprise the four phases of, G1, S-phase, G2 and mitosis. Two critical transitions are G1/S and G2/M; the latter is regulated by WEE1 kinase and CDC25 phosphatases. The scope of this thesis was to investigate the regulation of the G2/M transition of the cell cycle by WEE1 and CDC25, and how these genes interface with plant growth regulators in Arabidopsis thaliana. In Arabidopsis roots, the frequency of lateral roots was found to be increased by ectopic expression of Schizosaccharomyces pombe (Sp)cdc25e and reduced by Arath;WEE1 expression. I examined the effect of Arath;WEE1 and Spcdc25 on induction of shoots and roots in Arabidopsis hypocotyls in vitro. Hypocotyl explants from two over-expressing WEE1 lines , three T-DNA insertion lines and two expressing cdc25 (Spcdc25e) lines together with wild type (WT) were cultured on two-way gradients of kinetin (Kin) and naphthyl acetic acid (NAA). Below a threshold concentration of NAA (100 ng ml-1), WEE1 repressed morphogenesis in vitro, whereas at all NAA/Kin combinations Spcdc25 promoted morphogenesis (particularly root formation) over and above that in WT. Loss of function wee1-1 cultures were very similar to WT. Quantitative data indicated a significant increase in the frequency of root formation in Spcdc25e cultures compared with WT particularly at low Kin concentrations, and WEE1oe’s repressive effect was overcome by NAA but not Kin. In conclusion, WEE1 has a repressive effect on morphogenesis in vitro that can be overcome by auxin whereas Spcd25 by-passes a cytokinin requirement for the induction of morphogenesis in vitro. The role of CDC25 and WEE1 in DNA damage responses was also analysed. Two over-expressing Arath;CDC25 lines and T-DNA mutants showed no difference to WT either in standard conditions or zeocin-supplemented treatments. However, root length was longer in Arath;CDC25oe lines treated with hydroxyurea (HU) and lateral root number was increased compared to WT. This suggests a differential response of Arath;CDC25oe in the DNA replication (HU-induced) and DNA damage (zeocin-induced) checkpoints (Chapter 5). Finally the roles of WEE1 and CDC25 in cell cycle regulation were examined using tobacco TBY-2 cell cultures expressing Arath;WEE1, Nicotiana tabacum (Nicta)WEE1 or Arath;CDC25. Whilst Nicta;WEE1 lengthened G2 of the cell cycle, Arath;WEE1 had an unusual effect of shortening G2 phase and Arath;CDC25 had no observable effect (Chapter 6).

Higher education, professionalism and skills in the built environment: the impact of the new urban agenda on teaching and learning

In the mid-to-late 1990s, the New Urban Agenda initiated a rethinking of urban development strategies placing a greater focus on regeneration of central urban spaces. The skills and competencies required by urban planners and built environment professionals to successfully implement regeneration schemes tend to differ from those required for greenfield development. The working paper summarises skills and competencies required by urban regeneration practitioners and how they are delivered through public and/or private sector providers at present. The role of the newly established regional Centres of Excellence and the professional bodies of the Built Environment professions in defining skills and educational requirements and providing training are explored. An analysis of supply and demand of skills training reveals that there is a mismatch rather than a lack of provision. The report draws on a conference where research findings were presented and discussed. It concludes with suggestions for improving the skills provision at the local government as well as community level. Skills audits were found useful tools in defining training needs. A set of sample workshop programmes outline flexible, tailor-made approaches guaranteed to address specific and identified needs.

Elite Rugby Union Players Perceptions of Performance Analysis

This study provides an in depth insight into the current views and opinions of elite level rugby union players regarding the use of performance analysis as a tool for improving their own playing performance and in highlighting the strengths and weaknesses of upcoming opponents. A total of seventy-three elite level rugby union players from two clubs in Great Britain completed a semi-structured questionnaire. Additionally, four players completed a semi-structured interview and following inductive content analysis, four key themes emerged: (1) the use of video for player development, (2) preparing for a match, (3) using video for player reflection in addition to other psychological tools and (4) players suggestions for improvements to the clubs current performance analysis programme. The main finding of the study concludes that players viewed performance analysis as a beneficial and useful tool to support their development and preparation. As a result the study provides an insight into the use of performance analysis within professional rugby union, enabling rugby coaches and practitioners to gain an understanding and appreciation of the players views towards the clubs current provision. Additionally, the findings help build and strengthen the on-going knowledge coaches, analysts and researchers currently have regarding how players perceive performance analysis.

e-poltergeist

E-poltergeist takes over the user’s internet browser, automatically initiating Web searches without their permission. Web-based artwork which explores issues of user control when confronted with complex technological systems, questioning the limits of digital interactive arts as consensual reciprocal systems. e-poltergeist was a major web commission that marked an early stage of research in a larger enquiry by Craighead and Thomson into the relationship between live virtual data, global communications networks and instruction-based art, exploring how such systems can be re-contextualised within gallery environments. e-poltergeist presented the 'viewer' with a singular narrative by using live internet search-engine data that aimed to create a perpetual and virtually unstoppable cycle of search engine results, banner ads and moving windows as an interruption into the normal use of an internet browser. The work also addressed the ‘de-personalisation’ of internet use by sending a series of messages from the live search engine data that seemed to address the user directly: 'Is anyone there?'; 'Can anyone hear me?', 'Please help me!'; 'Nobody cares!' e-poltergeist makes a significant contribution to the taxonomy of new media art by dealing with the way that new media art can re-address notions of existing traditions in art such as appropriation and manipulation, instruction-based art and conceptual art. e-poltergeist was commissioned ($12,000) for 010101: Art in Technological Times, a landmark international exhibition presented by the San Francisco Museum of Modern Art, which bought together leading international practitioners working with emergent technologies, including Tatsuo Miyajima, Janet Cardiff, Brian Eno.

Plurality, policy and the local: can hyperlocals fill the gap?

Over the last 15 years, the acceleration in media consolidation has presented a series of policy challenges around diversity of editorial output. While policy debates on national ownership limits and other regulatory interventions are important, developments at the local level are often marginalised. And yet, the direction of travel—towards more consolidation and more deregulation—has arguably been more debilitating for democracy at the local level, where the vast majority of citizens interact with hospitals, schools, transport systems and local councils. The decline of local media—including, in some towns, the wholesale disappearance of local newspapers—leaves citizens starved of information and local institutions less accountable. This article uses an existing conceptual framework for assessing whether and how journalism makes a real-life contribution to democratic life at the local level. Against this normative framework, it then assesses the contribution of hyperlocal media sites to local democracy. We present findings from the most extensive survey of the hyperlocal sector to date, a collaboration with research partners at Cardiff and Birmingham City Universities and Talk About Local, which analysed online questionnaires from over 180 local online media initiatives. Our research offers a unique insight into the funding, operational problems and sustainability of community media sites, and suggests they have the potential to fulfil a vital democratic and civic role. These data inform our conclusions and recommendations for policy initiatives that would invigorate hyperlocal sites and therefore provide a real alternative for otherwise democratically impoverished local communities.

The effect of melanocortin peptides on Interleukin 1-beta induced chondrocyte cell death and inflammation

ntroduction: Osteoarthritis (OA) is a degenerative joint disease affecting more than 8.5 million people in the UK. Disruption in the catabolic and anabolic balance, with the catabolic cytokine Interleukin 1 beta (IL-1β) being involved in the initiation and progression of OA (1). Melanocortin peptides (α-MSH and D[Trp8]-γ-MSH) exert their anti-inflammatory effects via activation of melanocortin receptors (MC), with both MC1 and MC3 being identified as promising candidates as novel targets for OA (2). This study aims to assess the chondroprotective and anti-inflammatory effects of the pan melanocortin receptor agonist α-MSH and MC3 agonist D[Trp8]-γ-MSH following IL-1β chondrocyte stimulation. Methods: RT-PCR/ Western Blot: Human C-20/A4 chondrocytic cell-line were cultured in 6 well plates (1x106 cells/well) and harvested to determine MC and IL-1β expression by RT-PCR, and Western Blot. Cell-Culture: Cells were cultured in 96 well plates (1x106 cells/well) and stimulated with H2O2 (0.3%), TNF-α (60 pg/ml) or IL-1β (0-5000pg/ml) for 0-72h and cell viability determined. Drug Treatment: In separate experiments cells were pre-treated with 3 μg/ml α-MSH (Sigma-Aldrich Inc. Poole, UK), or D[Trp8]-γ-MSH (Phoenix Pharmaceuticals, Karlsrhue, Germany) (all dissolved in PBS) for 30 minutes prior to IL-1β (5000pg/ml) stimulation for 6-24h. Analysis: Cell viability was determined by using the three cell viability assays; Alamar Blue, MTT and the Neutral Red (NR) assay. Cell-free supernatants were collected and analysed for Interleukin -6 (IL-6) and IL-8 release by ELISA. Data expressed as Mean ± SD of n=4-8 determination in quadruplicate. *p≤ 0.05 vs. control. Results: Both RT-PCR, and Western Blot showed MC1 and MC3 expression on C-20/A4 cells. Cell viability analysis: IL-1β stimulation led to a maximal cell death of 35% at 6h (Alamar Blue), and 40% and 75% with MTT and Neutral Red respectively at 24h compared to control. The three cell viability assays have different cellular uptake pathways, which accounts for the variations observed in cell viability in response to the concentration of IL-1β, and time. Cytokine analysis by ELISA: IL-1β (5000pg/ml) stimulation for 6 and 24h showed maximal IL-6 production 292.3 ±3.8 and 275.5 ±5.0 respectively, and IL-8 production 353.3 ±2.6 and 598.3 ±8.6 respectively. Pre-treatment of cells with α-MSH and D[Trp8]-γ-MSH caused significant reductions in both IL-6 and IL-8 respectively following IL-1β stimulation at 6h. Conclusion: MC1/3 are expressed on C-20/A4 cells, activation by melanocortin peptides led to an inhibition of IL-1β induced cell death and pro-inflammatory cytokine release.
