Most UK financial institutions have failed during the recent financial crisis. Although this depression is triggered by the failure of US housing market, the business model for the UK is still different with US financial institutions. Most failed companies are not hold large amount of sub-prime loans in their asset portfolio in the UK, the most important reason is the wholesale funding strategies became the central business model for the most failed firms, therefore the retail deposits are no...

2011-11-01

Full Text Available Abstract Background Tuberculosis (TB has increased within the UK and, in response, targets for TB control have been set and interventions recommended. The question was whether these had been implemented and, if so, had they been effective in reducing TB cases. Methods Epidemiological data were obtained from enhanced surveillance and clinics. Primary care trusts or TB clinics with an average of > 100 TB cases per year were identified and provided reflections on the reasons for any change in their local incidence, which was compared to an audit against the national TB plan. Results Access to data for planning varied (0-22 months. Sputum smear status was usually well recorded within the clinics. All cities had TB networks, a key worker for each case, free treatment and arrangements to treat HIV co-infection. Achievement of targets in the national plan correlated well with change in workload figures for the commissioning organizations (Spearman's rank correlation R = 0.8, P 6% (χ2 = 4.2, P Conclusion TB control programmes depend on adequate numbers of specialist TB nurses for early detection and case-holding.

The development of integrated heat network strategies involving exploitation of the shallow subsurface requires knowledge of ground conditions at the feasibility stage, and throughout the life of the system. We describe an approach to the assessment of ground constraints and energy opportunities in data-rich urban areas. Geological and hydrogeological investigations have formed a core component of the strategy development for sustainable thermal use of the subsurface in Cardiff, UK. We present findings from a 12 month project titled 'Ground Heat Network at a City Scale', which was co-funded by NERC/BGS and the UK Government through the InnovateUK Energy Catalyst grant in 2015-16. The project examined the technical feasibility of extracting low grade waste heat from a shallow gravel aquifer using a cluster of open loop ground source heat pumps. Heat demand mapping was carried out separately. The ground condition assessment approach involved the following steps: (1) city-wide baseline groundwater temperature mapping in 2014 with seasonal monitoring for at least 12 months prior to heat pump installation (Patton et al 2015); (2) desk top and field-based investigation of the aquifer system to determine groundwater levels, likely flow directions, sustainable pumping yields, water chemistry, and boundary conditions; (3) creation of a 3D geological framework model with physical property testing and model attribution; (4) use steps 1-3 to develop conceptual ground models and production of maps and GIS data layers to support scenario planning, and initial heat network concept designs; (5) heat flow modelling in FEFLOW software to analyse sustainability and predict potential thermal breakthrough in higher risk areas; (6) installation of a shallow open loop GSHP research observatory with real-time monitoring of groundwater bodies to provide data for heat flow model validation and feedback for system control. In conclusion, early ground condition modelling and subsurface

Bell, Margaret Carol; Galatioto, Fabio; Chakravartty, Ayan; Namdeo, Anil

2013-01-01

This paper investigates the variations in levels of nitrogen dioxide, NO 2 , monitored over the decade 2001–2010, in Newcastle-upon-Tyne (UK) city centre, to develop fundamental understanding of the periods of persistence of levels of NO 2 greater than 40 μg m −3 (∼21 ppb) defined as air pollution event duration. The appropriateness of the hazard theory as a mechanism to understand failure rate of the duration of poor air pollution events was explored. The results revealed two types of air quality events. The longer duration air quality events (between 24 and 68 h) were associated with the “extreme-weather” conditions and were responsible for a small number of extremely long air pollution duration events. These created bias in the results and therefore the analysis was restricted specifically to the ‘normal-weather’ related air pollution event durations, conforming to a geometric distribution. This novel approach shows promise as a mechanism to monitor and investigate year on year trends observed in air quality data. -- Highlights: • Innovative method for the analysis of the duration of pollution events. • Hazard theory to better understand reasons of pollution events prevail year on year. • Duration of time of exceedences used as a parameter to assess trends in pollution. • Deteriorated or improved air quality from year to year over a decade investigated. -- Capsule: Explored appropriateness of the hazard theory to understand the failure rate of air pollution events and to investigate the year on year trends observed in air quality data in major cities

Transporting large monolithic shafts through the interior of the city of Rome

Directory of Open Access Journals (Sweden)

Patrizio Pensabene

2017-01-01

Full Text Available One of the questions we have to answer when studying the process of building Rome’s huge temples is how their large monolithic shafts were moved through the city. The shafts used in some of the temples were enormous. For example, the temple of Antoninus and Faustina in the Roman Forum and the Forum of Peace were built, respectively, with shafts of cipollino and granito rosa from Aswan. They would have had to have been taken through the city centre where manoeuvring such large loads through the narrow streets would not have been an easy task. We will attempt to hypothesise not only the possible routes along which these enormous blocks were transported, but also the mechanical operations that would have been needed to overcome the frequent obstacles that would have been encountered.

Large urban fire environment: trends and model city predictions

1983-01-01

The urban fire environment that would result from a megaton-yield nuclear weapon burst is considered. The dependence of temperatures and velocities on fire size, burning intensity, turbulence, and radiation is explored, and specific calculations for three model urban areas are presented. In all cases, high velocity fire winds are predicted. The model-city results show the influence of building density and urban sprawl on the fire environment. Additional calculations consider large-area fires with the burning intensity reduced in a blast-damaged urban center

Responses of Vegetation Cover to Environmental Change in Large Cities of China

Directory of Open Access Journals (Sweden)

Kai Jin

2018-01-01

Full Text Available Vegetation cover is crucial for the sustainability of urban ecosystems; however, this cover has been undergoing substantial changes in cities. Based on climate data, city statistical data, nighttime light data and the Normalized Difference Vegetation Index (NDVI dataset, we investigate the spatiotemporal variations of climate factors, urban lands and vegetation cover in 71 large cities of China during 1998–2012, and explore their correlations. A regression model between growing-season NDVI (G-NDVI and urban land proportion (PU is built to quantify the impact of urbanization on vegetation cover change. The results indicate that the spatiotemporal variations of temperature, precipitation, PU and G-NDVI are greatly different among the 71 cities which experienced rapid urbanization. The spatial difference of G-NDVI is closely related to diverse climate conditions, while the inter-annual variations of G-NDVI are less sensitive to climate changes. In addition, there is a negative correlation between G-NDVI trend and PU change, indicating vegetation cover in cities have been negatively impacted by urbanization. For most of the inland cities, the urbanization impacts on vegetation cover in urban areas are more severe than in suburban areas. But the opposite occurs in 17 cities mainly located in the coastal areas which have been undergoing the most rapid urbanization. Overall, the impacts of urbanization on G-NDVI change are estimated to be −0.026 per decade in urban areas and −0.015 per decade in suburban areas during 1998–2012. The long-term developments of cities would persist and continue to impact on the environmental change and sustainability. We use a 15-year window here as a case study, which implies the millennia of human effects on the natural biotas and warns us to manage landscapes and preserve ecological environments properly.

Optical Coherence Tomography in the UK Biobank Study - Rapid Automated Analysis of Retinal Thickness for Large Population-Based Studies.

Full Text Available To describe an approach to the use of optical coherence tomography (OCT imaging in large, population-based studies, including methods for OCT image acquisition, storage, and the remote, rapid, automated analysis of retinal thickness.In UK Biobank, OCT images were acquired between 2009 and 2010 using a commercially available "spectral domain" OCT device (3D OCT-1000, Topcon. Images were obtained using a raster scan protocol, 6 mm x 6 mm in area, and consisting of 128 B-scans. OCT image sets were stored on UK Biobank servers in a central repository, adjacent to high performance computers. Rapid, automated analysis of retinal thickness was performed using custom image segmentation software developed by the Topcon Advanced Biomedical Imaging Laboratory (TABIL. This software employs dual-scale gradient information to allow for automated segmentation of nine intraretinal boundaries in a rapid fashion.67,321 participants (134,642 eyes in UK Biobank underwent OCT imaging of both eyes as part of the ocular module. 134,611 images were successfully processed with 31 images failing segmentation analysis due to corrupted OCT files or withdrawal of subject consent for UKBB study participation. Average time taken to call up an image from the database and complete segmentation analysis was approximately 120 seconds per data set per login, and analysis of the entire dataset was completed in approximately 28 days.We report an approach to the rapid, automated measurement of retinal thickness from nearly 140,000 OCT image sets from the UK Biobank. In the near future, these measurements will be publically available for utilization by researchers around the world, and thus for correlation with the wealth of other data collected in UK Biobank. The automated analysis approaches we describe may be of utility for future large population-based epidemiological studies, clinical trials, and screening programs that employ OCT imaging.

During recent decades and centuries, pools and fluxes of Carbon, Nitrogen and Phosphorus (C, N and P) in UK rivers and ecosystems have been transformed by the spread and fertiliser-based intensification of agriculture (necessary to sustain human populations), by atmospheric pollution, by human waste (rising in line with population growth), and now by climate change. The principal objective of the UK's NERC-funded Macronutrients LTLS research project has been to account for observable terrestrial and aquatic pools, concentrations and fluxes of C, N and P on the basis of past inputs, biotic and abiotic interactions, and transport processes. More specifically, over the last 200 years, what have been the temporal responses of plant and soil nutrient pools in different UK catchments to nutrient enrichment, and what have been the consequent effects on nutrient transfers from land to the atmosphere, freshwaters and estuaries? The work described here addresses the second question by providing an integrated quantitative description of the interlinked land and water pools and annual fluxes of C, N and P for UK catchments over time. A national-scale modelling environment has been developed, combining simple physically-based gridded models that can be parameterised using recent observations before application to long timescales. The LTLS Integrated Model (LTLS-IM) uses readily-available driving data (climate, land-use, nutrient inputs, topography), and model estimates of both terrestrial and freshwater nutrient loads have been compared with measurements from sites across the UK. Here, the focus is on the freshwater nutrient component of the LTLS-IM, but the terrestrial nutrient inputs required for this are provided by models of nutrient processes in semi-natural and agricultural systems, and from simple models of nutrients arising from human waste. In the freshwater model, lateral routing of dissolved and particulate nutrients and within-river processing such as

The article is devoted to the problem of the negative impact of traffic noise on the health and living conditions of the population in conditions of the large city. Every day on the streets there are appeared more and more different modes of transport, and to date almost all transportation network has reached his traffic performance. The increase in traffic noise certainly has an impact on the human body. The most common and intense noise is caused by the traffic of urban automobile and electric transport. This is explained by the existence of the heavy traffic (2-3 thousand crews/h) on almost all main roads in historically emerged parts of the city. In addition, sources of external noise in the city can be a railway running in residential zone, access roads, industrial enterprises, located in close proximity to residential areas and on the borders of residential zones, planes of military and civil aviation. For the evaluation of the different noises sound levels were measured with the use of sound level meters. The most common parameter for the assessment ofthe noise generatedfrom motor vehicles on residential areas and usedfor the noise characteristics of the traffic flows, is the equivalent sound level/A EQ dB. This parameter is used in the majority of normative-technical documentation as hygienic noise standard. With the aim of the assessment of noise exposure there were selected 122 control points at intersections of roads of different traffic performance where there were made instrumental measurements the equivalent sound level, followed by its comparison with permissible levels.

The first UK city-wide heat map is described based on measurements of groundwater from a shallow superficial aquifer in the coastal city of Cardiff, Wales, UK. The UK Government has a target of reducing greenhouse gas emissions by 80% by 2050 (Climate Change Act 2008) and low carbon technologies are key to achieving this. To support the use of ground source heating we characterised the shallow heat potential of an urban aquifer to produce a baseline dataset which is intended to be used as a tool to inform developers and to underpin planning and regulation. We exploited an existing network of 168 groundwater monitoring boreholes across the city, recording the water temperature in each borehole at 1m depth intervals up to a depth of 20m. We recorded groundwater temperatures during the coldest part of 2014, and repeat profiling of the boreholes in different seasons has added a fourth dimension to our results and allowed us to characterise the maximum depth of seasonal temperature fluctuation. The temperature profiles were used to create a 3D model of heat potential within the aquifer using GOCAD® and the average borehole temperatures were contoured using Surfer® 10 to generate a 2D thermal resource map to support future assessment of urban Ground Source Heat Pumps prospectively. The average groundwater temperature in Cardiff was found to be above the average for England and Wales (11.3°C) with 90% of boreholes in excess of this figure by up to 4°C. The subsurface temperature profiles were also found to be higher than forecast by the predicted geothermal gradient for the area. Potential sources for heat include: conduction from buildings, basements and sub-surface infrastructure; insulation effects of the urban area and of the geology, and convection from leaking sewers. Other factors include recharge inhibition by drains, localised confinement and rock-water interaction in specific geology. It is likely to be a combination of multiple factors which we are hoping

Full Text Available Environmental factors are among the key determinants of real estate prices. They include landscape attractiveness, land relief, exposure to sunlight and proximity to natural features. In large urban centers, traffic noise emissions significantly affect decision-making on the real estate market. Weakly developed road networks and the absence of ring roads that shift road traffic outside residential districts are a widespread problem in the cities of Central-Eastern Europe. The prevention of traffic noise pollution, one of the key environmental problems in Europe, is an important goal of European Union policy. This paper analyzes the correlations between apartment prices and traffic noise levels in Olsztyn, the capital city of the Warminsko-Mazurskie Voivodeship (province in north-eastern Poland. A linear correlation analysis was performed, and the distribution of unit prices of apartments was mapped by ordinary kriging.

Little is known about tobacco promotion activities in low and middle-income countries. Information on tobacco sales, advertisement and promotion in bars, cafes and nightclubs is needed to develop interventions to reduce smoking initiation and relapse, particularly among youths and young adults. To evaluate cigarette sales and tobacco advertisement and promotion in bars, cafes and nightclubs using a volunteer survey approach in large cities throughout the world. Between 2007 and 2009, we administered an interview-based survey to 231 bar/cafe/nightclub owners/managers in 24 large cities in Africa, the Americas, Asia and eastern Europe. Cigarette sales and tobacco advertisement and promotions were found in bars/cafes/nightclubs in most cities. Examples of promotions included cigarette giveaways and event sponsorship. Establishments that allowed smoking were more likely to sell cigarettes compared to smoke-free establishments (OR 8.67, 95% CI 3.25 to 23.1). Larger establishments (maximum occupancy ≥ 100 vs promotional items from tobacco companies (OR 3.18, 95% CI 1.41 to 7.17). Cigarette sales and tobacco promotions were common in bars, cafes and nightclubs in the majority of cities. Socialising and hospitality venues must be covered by legislation banning tobacco sales and promotions to limit exposure among populations at high risk of tobacco initiation and relapse from quitting.

By measuring alcohol retailers' propensity to illegally sell alcohol to young people who appear highly intoxicated, we examine whether UK legislation is effective at preventing health harms resulting from drunk individuals continuing to access alcohol. 73 randomly selected pubs, bars and nightclubs in a city in North West England were subjected to an alcohol purchase test by pseudo-drunk actors. Observers recorded venue characteristics to identify poorly managed and problematic (PMP) bars. 83.6% of purchase attempts resulted in a sale of alcohol to a pseudo-intoxicated actor. Alcohol sales increased with the number of PMP markers bars had, yet even in those with no markers, 66.7% of purchase attempts resulted in a sale. Bar servers often recognised signs of drunkenness in actors, but still served them. In 18% of alcohol sales, servers attempted to up-sell by suggesting actors purchase double rather than single vodkas. UK law preventing sales of alcohol to drunks is routinely broken in nightlife environments, yet prosecutions are rare. Nightlife drunkenness places enormous burdens on health and health services. Preventing alcohol sales to drunks should be a public health priority, while policy failures on issues, such as alcohol pricing, are revisited.

Spatio-Semantic Comparison of Large 3d City Models in Citygml Using a Graph Database

Nguyen, S. H.; Yao, Z.; Kolbe, T. H.

2017-10-01

A city may have multiple CityGML documents recorded at different times or surveyed by different users. To analyse the city's evolution over a given period of time, as well as to update or edit the city model without negating modifications made by other users, it is of utmost importance to first compare, detect and locate spatio-semantic changes between CityGML datasets. This is however difficult due to the fact that CityGML elements belong to a complex hierarchical structure containing multi-level deep associations, which can basically be considered as a graph. Moreover, CityGML allows multiple syntactic ways to define an object leading to syntactic ambiguities in the exchange format. Furthermore, CityGML is capable of including not only 3D urban objects' graphical appearances but also their semantic properties. Since to date, no known algorithm is capable of detecting spatio-semantic changes in CityGML documents, a frequent approach is to replace the older models completely with the newer ones, which not only costs computational resources, but also loses track of collaborative and chronological changes. Thus, this research proposes an approach capable of comparing two arbitrarily large-sized CityGML documents on both semantic and geometric level. Detected deviations are then attached to their respective sources and can easily be retrieved on demand. As a result, updating a 3D city model using this approach is much more efficient as only real changes are committed. To achieve this, the research employs a graph database as the main data structure for storing and processing CityGML datasets in three major steps: mapping, matching and updating. The mapping process transforms input CityGML documents into respective graph representations. The matching process compares these graphs and attaches edit operations on the fly. Found changes can then be executed using the Web Feature Service (WFS), the standard interface for updating geographical features across the web.

Why are large cities faster? Universal scaling and self-similarity in urban organization and dynamics

Cities have existed since the beginning of civilization and have always been intimately connected with humanity's cultural and technological development. Much about the human and social dynamics that takes place is cities is intuitively recognizable across time, space and culture; yet we still do not have a clear cut answer as to why cities exist or to what factors are critical to make them thrive or collapse. Here, we construct an extensive quantitative characterization of the variation of many urban indicators with city size, using large data sets for American, European and Chinese cities. We show that social and economic quantities, characterizing the creation of wealth and new ideas, show increasing returns to population scale, which appear quantitatively as a power law of city size with an exponent β≃ 1.15 > 1. Concurrently, quantities characterizing material infrastructure typically show economies of scale, namely β≃ 0.8 exponential growth, which inexorably lead to crises of urban organization. To avoid them we show that growth may proceed in cycles, separated by major urban adaptations, with the unintended consequence that the duration of such cycles decreases with larger urban population size and is now estimated to be shorter than a human lifetime.

Environmental change caused by urban development, possibly augmented by climate change, may result in accelerated decay of in situ archaeological resources. Damage may be related to changes in hydrological processes. Such archaeological resources have to be considered in environmental planning. In this paper we highlight the need for improved hydrological data from urban archaeological sites using the case study of the City of York, UK, arguably one of the most well studied and well preserved urban archaeological environments globally. We suggest that the quality of hydrological data collected during routine surveys and experimental work must be improved and standardised in order for us to produce reliable archaeological risk models for urban sites.

A Methodology of Health Effects Estimation from Air Pollution in Large Asian Cities

Directory of Open Access Journals (Sweden)

Keiko Hirota

2017-09-01

Full Text Available The increase of health effects caused by air pollution seems to be a growing concern in Asian cities with increasing motorization. This paper discusses methods of estimating the health effects of air pollution in large Asian cities. Due to the absence of statistical data in Asia, this paper carefully chooses the methodology using data of the Japanese compensation system. A basic idea of health effects will be captured from simple indicators, such as population and air quality, in a correlation model. This correlation model enables more estimation results of respiratory mortality caused by air pollution to be yielded than by using the relative model. The correlation model could be an alternative method to estimate mortality besides the relative risk model since the results of the correlation model are comparable with those of the relative model by city and by time series. The classification of respiratory diseases is not known from the statistical yearbooks in many countries. Estimation results could support policy decision-making with respect to public health in a cost-effective way.

Over the last decade, climate change has moved from being the concern of few to a widely recognized threat to humanity itself and the natural environment. The 1990s were the warmest decade on record, and ever-increasing atmospheric levels of greenhouse gases such as carbon dioxide (CO/sub 2/), could, if left unchecked lead to serious consequences globally, including increased risks of droughts, floods and storms, disruption to agriculture, rising sea levels and the spread of disease. The contribution of anthropogenic emissions of carbon dioxide has been recognized as the principal cause of the atmospheric changes that drive these climate trends. Globally, buildings are the largest source of indirect carbon emissions. In 2000, the UK Royal Commission on Environmental Pollution estimated that in order to stabilise carbon emissions at levels, which avoid catastrophic alterations in the climate, we would have to reduce emissions from the built environment by at least 60% by 2050 and 80% by 2100 relative to 1997 levels. Studies of the Oxford Ecohouse have demonstrated that it is not difficult to reduce carbon emissions from houses by 60% or more through energy efficiency measures, but it is only possible to reach the 90% level of reductions required by using renewable energy technologies. Solar energy technologies have been the most successfully applied of all renewable to date largely because they are the only systems that can be incorporated easily into the urban fabric. In addition, the short fossil fuel horizons that are predicted (c. 40 years left for oil and 65 years for gas) will drive the markets for solar technologies. For these reasons, the cities of the future will be powered by solar energy, to a greater or lesser extent, depending on the city form and location. In recognition of the need to move rapidly towards a renewable energy future, a group of international cities, including Oxford, have started the Solar City Network. In this paper we outline the

Air pollution is an important public health concern especially for children who are particularly susceptible. Latin America has a large children population, is highly urbanized and levels of pollution are substantially high, making the potential health impact of air pollution quite large. We evaluated the effect of air pollution on children respiratory mortality in four large urban centers: Mexico City, Santiago, Chile, and Sao Paulo and Rio de Janeiro in Brazil. Generalized Additive Models in Poisson regression was used to fit daily time-series of mortality due to respiratory diseases in infants and children, and levels of PM 10 and O 3 . Single lag and constrained polynomial distributed lag models were explored. Analyses were carried out per cause for each age group and each city. Fixed- and random-effects meta-analysis was conducted in order to combine the city-specific results in a single summary estimate. These cities host nearly 43 million people and pollution levels were above the WHO guidelines. For PM 10 the percentage increase in risk of death due to respiratory diseases in infants in a fixed effect model was 0.47% (0.09-0.85). For respiratory deaths in children 1-5 years old, the increase in risk was 0.58% (0.08-1.08) while a higher effect was observed for lower respiratory infections (LRI) in children 1-14 years old [1.38% (0.91-1.85)]. For O 3 , the only summarized estimate statistically significant was for LRI in infants. Analysis by season showed effects of O 3 in the warm season for respiratory diseases in infants, while negative effects were observed for respiratory and LRI deaths in children. We provided comparable mortality impact estimates of air pollutants across these cities and age groups. This information is important because many public policies aimed at preventing the adverse effects of pollution on health consider children as the population group that deserves the highest protection.

Hydro-meteorological extremes such as drought and heavy precipitation can have large impacts on society and the economy. With potentially increasing risks associated with such events due to climate change, properly assessing the associated impacts and uncertainties is critical for adequate adaptation. However, the application of risk-based approaches often requires large sets of extreme events, which are not commonly available. Here, we present such a large set of hydro-meteorological time series for recent past and future conditions for the United Kingdom based on weather@home 2, a modelling framework consisting of a global climate model (GCM) driven by observed or projected sea surface temperature (SST) and sea ice which is downscaled to 25 km over the European domain by a regional climate model (RCM). Sets of 100 time series are generated for each of (i) a historical baseline (1900-2006), (ii) five near-future scenarios (2020-2049) and (iii) five far-future scenarios (2070-2099). The five scenarios in each future time slice all follow the Representative Concentration Pathway 8.5 (RCP8.5) and sample the range of sea surface temperature and sea ice changes from CMIP5 (Coupled Model Intercomparison Project Phase 5) models. Validation of the historical baseline highlights good performance for temperature and potential evaporation, but substantial seasonal biases in mean precipitation, which are corrected using a linear approach. For extremes in low precipitation over a long accumulation period ( > 3 months) and shorter-duration high precipitation (1-30 days), the time series generally represents past statistics well. Future projections show small precipitation increases in winter but large decreases in summer on average, leading to an overall drying, consistently with the most recent UK Climate Projections (UKCP09) but larger in magnitude than the latter. Both drought and high-precipitation events are projected to increase in frequency and intensity in most regions

Objectives: Air pollution is an important public health concern especially for children who are particularly susceptible. Latin America has a large children population, is highly urbanized and levels of pollution are substantially high, making the potential health impact of air pollution quite large. We evaluated the effect of air pollution on children respiratory mortality in four large urban centers: Mexico City, Santiago, Chile, and Sao Paulo and Rio de Janeiro in Brazil. Methods: Generalized Additive Models in Poisson regression was used to fit daily time-series of mortality due to respiratory diseases in infants and children, and levels of PM 10 and O 3 . Single lag and constrained polynomial distributed lag models were explored. Analyses were carried out per cause for each age group and each city. Fixed- and random-effects meta-analysis was conducted in order to combine the city-specific results in a single summary estimate. Results: These cities host nearly 43 million people and pollution levels were above the WHO guidelines. For PM 10 the percentage increase in risk of death due to respiratory diseases in infants in a fixed effect model was 0.47% (0.09–0.85). For respiratory deaths in children 1–5 years old, the increase in risk was 0.58% (0.08–1.08) while a higher effect was observed for lower respiratory infections (LRI) in children 1–14 years old [1.38% (0.91–1.85)]. For O 3 , the only summarized estimate statistically significant was for LRI in infants. Analysis by season showed effects of O 3 in the warm season for respiratory diseases in infants, while negative effects were observed for respiratory and LRI deaths in children. Discussion: We provided comparable mortality impact estimates of air pollutants across these cities and age groups. This information is important because many public policies aimed at preventing the adverse effects of pollution on health consider children as the population group that deserves the highest protection

Objectives To describe predictors of pregnancy and changes in pregnancy incidence among HIV-positive women accessing HIV clinical care. Methods Data were obtained through the linkage of two separate studies; the UK Collaborative HIV Cohort study (UK CHIC), a cohort of adults attending 13 large HIV clinics, and the National Study of HIV in Pregnancy and Childhood (NSHPC), a national surveillance study of HIV-positive pregnant women. Pregnancy incidence was measured using the proportion of women in UK CHIC with a pregnancy reported to NSHPC. Generalised estimating equations were used to identify predictors of pregnancy and assess changes in pregnancy incidence in 2000-2009. Results The number of women accessing care at UK CHIC sites increased as did the number of pregnancies (from 72 to 230). Older women were less likely to have a pregnancy (adjusted Relative Rate (aRR) 0.44 per 10 year increment in age [95% CI [0.41-0.46], ppregnancy increased over the study period (aRR 1.05 [1.03-1.07], ppregnancy rate among women accessing HIV clinical care increased in 2000-2009. HIV-positive women with, or planning, a pregnancy require a high level of care and this is likely to continue and increase as more women of older age have pregnancies. PMID:22713479

The future of UK gas producers

International Nuclear Information System (INIS)

Hallas, P.A.

1991-01-01

Traditionally, an oil company wishing to develop UK gas reserves almost always faced a protracted gas sales negotiation with British Gas. British Gas then had an effective monopoly in the resale of that gas to final consumers. This traditional pattern is now in a process of fundamental change, as a result of recent UK gas market re-regulation and the emergence of a new large scale opportunity to sell gas for power generation. The impact of these changes is still not very well understood outside a relatively small group of gas specialists but is likely to be significant for British Gas, consumers and UK gas producers. This paper outlines the background to the recent changes, the possible future of UK gas marketing and the likely impact on gas producers in the North Sea

UK Announces Intention to Join ESO

Science.gov (United States)

2000-11-01

Summary The Particle Physics and Astronomy Research Council (PPARC) , the UK's strategic science investment agency, today announced that the government of the United Kingdom is making funds available that provide a baseline for this country to join the European Southern Observatory (ESO) . The ESO Director General, Dr. Catherine Cesarsky , and the ESO Community warmly welcome this move towards fuller integration in European astronomy. "With the UK as a potential member country of ESO, our joint opportunities for front-line research and technology will grow significantly", she said. "This announcement is a clear sign of confidence in ESO's abilities, most recently demonstrated with the construction and operation of the unique Very Large Telescope (VLT) on Paranal. Together we will look forward with confidence towards new, exciting projects in ground-based astronomy." It was decided earlier this year to place the 4-m UK Visible and Infrared Survey Telescope (VISTA) at Paranal, cf. ESO Press Release 03/00. Following negotiations between ESO and PPARC, a detailed proposal for the associated UK/ESO Agreement with the various entry modalities will now be presented to the ESO Council for approval. Before this Agreement can enter into force, the ESO Convention and associated protocols must also be ratified by the UK Parliament. Research and key technologies According to the PPARC press release, increased funding for science, announced by the UK government today, will enable UK astronomers to prepare for the next generation of telescopes and expand their current telescope portfolio through membership of the European Southern Observatory (ESO). The uplift to its baseline budget will enable PPARC to enter into final negotiations for UK membership of the ESO. This will ensure that UK astronomers, together with their colleagues in the ESO member states, are actively involved in global scale preparations for the next generation of astronomy facilities. among these are ALMA

Large-scale solar purchasing

The principal objective of the project was to participate in the definition of a new IEA task concerning solar procurement (''the Task'') and to assess whether involvement in the task would be in the interest of the UK active solar heating industry. The project also aimed to assess the importance of large scale solar purchasing to UK active solar heating market development and to evaluate the level of interest in large scale solar purchasing amongst potential large scale purchasers (in particular housing associations and housing developers). A further aim of the project was to consider means of stimulating large scale active solar heating purchasing activity within the UK. (author)

Simple Summary While the overall trend in euthanasia has been decreasing nationally, large dogs are at a higher risk of euthanasia than other-sized dogs in most animal shelters in the United States. We hypothesized that one way to increase the lives saved with regard to large dogs in shelters is to keep them home in the first place when possible. Our research is the first to collect data in New York City and Washington, D.C., identifying the process leading to the owner relinquishment of large dogs. We found that targets for interventions to decrease large dog relinquishment are likely different in each community. Abstract While the overall trend in euthanasia has been decreasing nationally, large dogs are at a higher risk of euthanasia than other sized dogs in most animal shelters in the United States. We hypothesized one way to increase the lives saved with respect to these large dogs is to keep them home when possible. In order to develop solutions to decrease relinquishment, a survey was developed to learn more about the reasons owners relinquish large dogs. The survey was administered to owners relinquishing their dogs at two large municipal facilities, one in New York City and one in Washington, D.C. There were 157 responses between the two facilities. We found both significant similarities and differences between respondents and their dogs from the two cities. We identified opportunities to potentially support future relinquishers and found that targets for interventions are likely different in each community. PMID:26480315

To tackle climate change it is essential to reduce carbon dioxide emissions. To this end, it is important to reduce the energy demands of non-domestic buildings. Naturally ventilated buildings can have low energy demands but the strategy is difficult to implement in deep plan, urban locations. The Frederick Lanchester Library at Coventry University, UK, incorporates natural ventilation, daylighting and passive cooling strategies. By using lightwells and perimeter stacks to supply and exhaust air, it can be ventilated by natural means despite its deep plan form and sealed facade. This paper describes the building and presents the energy consumption and the internal temperatures and CO{sub 2} levels recorded in 2004/2005. The building's performance is compared to the original design criteria and good practice guidelines. Recommendations for the design of such buildings are made and the likely performance in other UK cities is assessed. It is concluded that the building uses under half the energy of a standard air-conditioned building and yet, in summer, can keep the interior comfortable and up to 5 deg C below ambient. The design would perform equally well in the typical weather conditions experienced at 13 other UK cities, but not in London. It is concluded that deep-plan, naturally ventilated buildings with sealed facades, if well designed, could maintain thermal comfort in all but a very few UK locations, whilst consuming much less energy than even good practice standards.

Full Text Available Despite increasing understanding of, information about and official commitment to challenge these patterns, racist hostility and violence continue to have an enduring presence in urban and rural life in the UK. This indicates the paradoxical nature of this racial crisis and challenges for antiracism as a political project. This paper charts how these issues play out at the local level through an examination of a five year process from problem identification through to research, response, action and aftermath from 2006 to 2012 in the city of Leeds, UK, with a focus on two predominantly white working class social housing estates in the city. We explore how embedded tensions and antagonisms can begin to be challenged, while examining how the contemporary climate of austerity and cuts in services, together with prevailing post-racial thinking, make the likelihood of such concerted action in the UK increasingly remote.

Full Text Available Large-scale prospective cohort studies are invaluable in epidemiology, but they are increasingly difficult and costly to establish and follow-up. More efficient methods for recruitment, data collection and follow-up are essential if such studies are to remain feasible with limited public and research funds. Here, we discuss how these challenges were addressed in the UK COSMOS cohort study where fixed budget and limited time frame necessitated new approaches to consent and recruitment between 2009-2012. Web-based e-consent and data collection should be considered in large scale observational studies, as they offer a streamlined experience which benefits both participants and researchers and save costs. Commercial providers of register and marketing data, smartphones, apps, email, social media, and the internet offer innovative possibilities for identifying, recruiting and following up cohorts. Using examples from UK COSMOS, this article sets out the dos and don'ts for today's cohort studies and provides a guide on how best to take advantage of new technologies and innovative methods to simplify logistics and minimise costs. Thus a more streamlined experience to the benefit of both research participants and researchers becomes achievable.

UK nuclear power: gone but not forgotten

International Nuclear Information System (INIS)

Anon.

1990-01-01

The nuclear power industry in Britain will not now be privatised. The future of nuclear power in the UK is discussed. In Scotland the South of Scotland Electricity Board will be expecting to sell some of its electricity to Britain. The structure of the new electricity supply industry in Scotland will also be unusual with most of the country's electricity being produced by a state-run company, while two private companies produce the rest and sell it on to customers. The situation in England is uncertain mainly because of the policy and potential costs involved in decommissioning of the Magnox stations as they are shutdown at the end of their service life. The privatisation of the electricity industry has highlighted the problems of decommissioning. It has also shown that the nuclear industry assumed itself to be immortal and has also assumed that money is not important, an attitude which has alarmed the City financiers. (UK)

Infections caused by Legionella are the leading cause of waterborne disease outbreaks in the United States. We investigated a large outbreak of Legionnaires' disease in New York City in summer 2015 to characterize patients, risk factors for mortality, and environmental exposures. We defined cases as patients with pneumonia and laboratory evidence of Legionella infection from July 2 through August 3, 2015, and with a history of residing in or visiting 1 of several South Bronx neighborhoods of New York City. We describe the epidemiologic, environmental, and laboratory investigation that identified the source of the outbreak. We identified 138 patients with outbreak-related Legionnaires' disease, 16 of whom died. The median age of patients was 55. A total of 107 patients had a chronic health condition, including 43 with diabetes, 40 with alcoholism, and 24 with HIV infection. We tested 55 cooling towers for Legionella, and 2 had a strain indistinguishable by pulsed-field gel electrophoresis from 26 patient isolates. Whole-genome sequencing and epidemiologic evidence implicated 1 cooling tower as the source of the outbreak. A large outbreak of Legionnaires' disease caused by a cooling tower occurred in a medically vulnerable community. The outbreak prompted enactment of a new city law on the operation and maintenance of cooling towers. Ongoing surveillance and evaluation of cooling tower process controls will determine if the new law reduces the incidence of Legionnaires' disease in New York City.

Mammalian UK114 belongs to a highly conserved family of proteins with unknown functions. Although it is believed that UK114 is a cytosolic or mitochondrial protein there is no detailed study of its intracellular localization. Using analytical subcellular fractionation, electron microscopic colloidal gold technique, and two-dimensional gel electrophoresis of peroxisomal matrix proteins combined with mass spectrometric analysis we show here that a large portion of UK114 is present in rat liver peroxisomes. The peroxisomal UK114 is a soluble matrix protein and it is not inducible by the peroxisomal proliferator clofibrate. The data predict involvement of UK114 in peroxisomal metabolism

The problems of ensuring the safety of nuclear facilities and other facilities representing a radiation hazard (hereinafter referred to as 'nuclear facilities') which are located in large cities are considered in the light of the experience with the 'Kurchatov Institute' Russian Research Centre. The accumulation of substantial quantities of spent nuclear fuel and radwaste at the Centre was an inevitable consequence of the military and civilian nuclear research programmes which started there in 1943. A comprehensive programme has been developed for reducing the impact of ionizing radiation on the Centre's personnel, the population living near the Centre and the local environment. The authors describe the basic elements of a programme for decommissioning reactor facilities and eliminating spent fuel and radwaste storage sites and also describe how the programme is progressing.

Playable cities the city as a digital playground

CERN Document Server

2017-01-01

This book addresses the topic of playable cities, which use the ‘smartness’ of digital cities to offer their citizens playful events and activities. The contributions presented here examine various aspects of playable cities, including developments in pervasive and urban games, the use of urban data to design games and playful applications, architecture design and playability, and mischief and humor in playable cities. The smartness of digital cities can be found in the sensors and actuators that are embedded in their environment. This smartness allows them to monitor, anticipate and support our activities and increases the efficiency of the cities and our activities. These urban smart technologies can offer citizens playful interactions with streets, buildings, street furniture, traffic, public art and entertainment, large public displays and public events.

Habitat composition and connectivity predicts bat presence and activity at foraging sites in a large UK conurbation.

Hale, James D; Fairbrass, Alison J; Matthews, Tom J; Sadler, Jon P

Urbanization is characterized by high levels of sealed land-cover, and small, geometrically complex, fragmented land-use patches. The extent and density of urbanized land-use is increasing, with implications for habitat quality, connectivity and city ecology. Little is known about densification thresholds for urban ecosystem function, and the response of mammals, nocturnal and cryptic taxa are poorly studied in this respect. Bats (Chiroptera) are sensitive to changing urban form at a species, guild and community level, so are ideal model organisms for analyses of this nature. We surveyed bats around urban ponds in the West Midlands conurbation, United Kingdom (UK). Sites were stratified between five urban land classes, representing a gradient of built land-cover at the 1 km(2) scale.

Full Text Available Urbanization is characterized by high levels of sealed land-cover, and small, geometrically complex, fragmented land-use patches. The extent and density of urbanized land-use is increasing, with implications for habitat quality, connectivity and city ecology. Little is known about densification thresholds for urban ecosystem function, and the response of mammals, nocturnal and cryptic taxa are poorly studied in this respect. Bats (Chiroptera are sensitive to changing urban form at a species, guild and community level, so are ideal model organisms for analyses of this nature.We surveyed bats around urban ponds in the West Midlands conurbation, United Kingdom (UK. Sites were stratified between five urban land classes, representing a gradient of built land-cover at the 1 km(2 scale.

The qualitative findings illustrate how diverse these three groups’ attitudes of tolerance can be and how they are affected...... by their position and status in the U.K. The British’ attitudes show their tolerance can reflect diverse forms of acceptance of ethnic and cultural differences but can also draw lines in terms of civic values opposing ‘those who contribute to society’ versus those who ‘live as parasites’. The Turks are in favour......Relying on a quantitative survey (n = 1497) and semi-structured interviews (n = 30) conducted in the U.K., we explore British nationals’, Romanian and Turkish migrants’ attitudes of tolerance and the factors influencing them in the current socio-political context in the U.K. The quantitative data...

Multisector Health Policy Networks in 15 Large US Cities

Science.gov (United States)

Leider, J. P.; Carothers, Bobbi J.; Castrucci, Brian C.; Hearne, Shelley

2016-01-01

Context: Local health departments (LHDs) have historically not prioritized policy development, although it is one of the 3 core areas they address. One strategy that may influence policy in LHD jurisdictions is the formation of partnerships across sectors to work together on local public health policy. Design: We used a network approach to examine LHD local health policy partnerships across 15 large cities from the Big Cities Health Coalition. Setting/Participants: We surveyed the health departments and their partners about their working relationships in 5 policy areas: core local funding, tobacco control, obesity and chronic disease, violence and injury prevention, and infant mortality. Outcome Measures: Drawing on prior literature linking network structures with performance, we examined network density, transitivity, centralization and centrality, member diversity, and assortativity of ties. Results: Networks included an average of 21.8 organizations. Nonprofits and government agencies made up the largest proportions of the networks, with 28.8% and 21.7% of network members, whereas for-profits and foundations made up the smallest proportions in all of the networks, with just 1.2% and 2.4% on average. Mean values of density, transitivity, diversity, assortativity, centralization, and centrality showed similarity across policy areas and most LHDs. The tobacco control and obesity/chronic disease networks were densest and most diverse, whereas the infant mortality policy networks were the most centralized and had the highest assortativity. Core local funding policy networks had lower scores than other policy area networks by most network measures. Conclusion: Urban LHDs partner with organizations from diverse sectors to conduct local public health policy work. Network structures are similar across policy areas jurisdictions. Obesity and chronic disease, tobacco control, and infant mortality networks had structures consistent with higher performing networks, whereas

An eye for the green top : an independent voice for green roofs in the UK

Energy Technology Data Exchange (ETDEWEB)

Frith, M.; Gedge, D. [Livingroofs.org, England (United Kingdom)

2005-07-01

Livingroofs.org is a non-profit organization that was established to provide a resource for promoting green roofs in the United Kingdom (UK). Current policies in the UK related to the planning and development of green roofs are a constraint to their uptake. The emerging emphasis on sustainable development is bringing about a revision of planning policies that may make green roofs more desirable. However, green roof design standards are still being developed by a largely unmonitored industry furthering a product with which most people are unfamiliar. This paper reviewed a number of issues that need to be addressed to assist in the wider adoption of green roofs, including increased awareness; an identification of the real benefits of green roofs; guidance and research; planning policies; fiscal incentives; industry standards and codes of practice. Details of the current policy frameworks for construction, urban design and climate change were also outlined. Two specific projects were reviewed to provide an insight into the way in which Livingroofs.org intends to promote green roof technology: a roof owned by the Birmingham city council and a collaboration with a Swiss partner to design a roof for the Komodo Dragon House at the London Zoo. It was concluded that there is now a real likelihood that the widespread adoption of green roofs will occur in the UK within the next 5 years, both in terms of new developments and the vast potential for retro-fitting on existing buildings. 47 refs., 2 tabs.

The results of synchronous sodar`s measurements on a territory of city and suburban area have shown: (a) The types of stratification over centre of the city and periphery considerably differ, and these distinctions are more often displayed in morning and evening transition period. The agreement between types of stratification in the centre and on the periphery was observed in 40% of cases; (b) At equal temperature stratification the mixed-layer depth in centre of the city is about 50-150 m higher at inversions in comparison with a periphery, at advanced convection - these depths are identical; (c) At different stratification between the city and periphery the distinction in the mixed-layer depth can reach 200.

Urban areas, being warmer than their surroundings, are particularly vulnerable to global warming and associated increases in extreme temperatures. Yet ensemble climate-model projections are generally performed on a scale that is too coarse to represent the evolution of temperatures in cities. Here, for the first time, we combine a 35-year convection-permitting climate model integrations with information from an ensemble of general circulation models to assess heat stress in a typical densely populated mid-latitude maritime region. We show that the heat-stress increase for the mid-21st century is twice as large in cities compared to their surrounding rural areas. The exacerbation is driven by the urban heat island itself, its concurrence with heatwaves, and urban expansion. Cities experience a heat-stress multiplication by a factor 1.4 and 15 depending on the scenario. Remarkably, the future heat-stress surpasses everywhere the urban hot spots of today. Our novel insights exemplify the need to combine information from climate models, acting on different scales, for climate-change risk assessment in heterogeneous regions. Moreover, these results highlight the necessity for adaptation to increasing heat stress, especially in urban areas.

Landscape planning for a safe city

Directory of Open Access Journals (Sweden)

M. Ishikawa

2002-06-01

Full Text Available To create a safe city free from natural disasters has been one of the important criteria in city planning. Since large cities have suffered from large fires caused by earthquakes, the planning of open spaces to prevent the spread of fires is part of the basic structure of city planning in Japan. Even in the feudal city of Edo, the former name of Tokyo, there had been open spaces to prevent fire disasters along canals and rivers. This paper discusses the historical evolution of open space planning, that we call landscape planning, through the experiences in Tokyo, and clarifies the characteristics and problems for achieving a safe city.

UK experience of planning the nuclear contribution to the UK power programme

International Nuclear Information System (INIS)

Catchpole, S.; Jenkin, F.P.

1977-01-01

The paper outlines U.K. experience in planning nuclear programmes. It examines the factors which have determined the size of such programmes together with those factors which have influenced their implementation. The paper also discusses the role which the utility has played in the deployment of nuclear power in the U.K. At present, nuclear energy can only be utilised on a large scale via the electricity route and the forecasting of electricity demand is therefore a key element in determining the size of the nuclear programme. Other important issues which affect the nuclear contribution are: national fuel policies, discontinuities in price and availability of imported fossil fuels, plant capital costs, fuel price relativities, plant siting, rate of introduction of new nuclear systems, manufacturer's capability, public attitudes towards nuclear power and financing. These issues are dealt with in some detail including their relative importance in the U.K. The paper also discusses the contribution of the various nuclear bodies in the U.K. in securing the implementation of the nuclear programmes. From the inception of nuclear power in the U.K., it has been recognised that a major utility has a central role to play not only in commercial operation but also in the procurement of plant and materials. As explained in the paper this ''informed buyer'' approach, which is being increasingly adopted by other major utilities, calls for an organisation and technical infrastructure far more complex than is the case for fossil plants. The requirements of safety, which is unambiguously the responsibility of the utility, and of high availability of plant operation demand a rigorous approach to design, quality assurance, project management, construction and operation. To this must be added sound research and development and staff training facilities. The paper explains how experience in these vital areas has been built up

Nuclear prospects in the UK

International Nuclear Information System (INIS)

Hawley, Robert

1993-01-01

During the late 1980s and early 1990s the UK government decided to privatise the UK electricity supply industry. In order to introduce competition into the generation side of the business it was decided that the large generating boards - the Central Electricity Generating Board (CEGB) and in Scotland, the South of Scotland Electricity Board and North of Scotland Hydro Board, - should be split up into smaller companies. In England and Wales two companies were proposed. The larger company National Power would include the nuclear generating business in England and Wales, the smaller company, Power Gen would use fossil generation only. Scotland was also to have two companies, Scottish Power - including Scotland's nuclear stations - and Scottish Hydro. But these were troubled times for the UK nuclear industry. A lot of misinformation was being issued by its opponents, in particular about decommissioning and fuel reprocessing costs. Looking back I can see there were reasons for that. Both National Power and Scottish Power wanted to be absolutely certain that they got the best possible deal and that every imaginable, and unimaginable, cost that may ever arise would be taken care of. This attitude resulted in the estimate of huge liabilities and 'unprecedented guarantees' that the then Secretary of State for Energy in the UK, could not accept

Urbanization and economic development: a bias toward large cities?

Science.gov (United States)

Moomaw, R L; Shatter, A M

1996-01-01

"We find that a nation's urban population percentage increases with GDP per capita; industrialization; export orientation; and possibly, foreign assistance. It decreases with the importance of agriculture. Industrialization and agricultural importance have the same implications for the concentration of urban population in cities with 100,000+ population as for the urban percentage. Greater export orientation reduces such concentration. Finally, GDP per capita, population, and export orientation reduce primacy. Political factors, such as whether a country's largest city is also its capital, affect primacy. Our results do not seem to imply that developing-country urbanization today differs fundamentally from urbanization in the past." excerpt

Report on primate supply for biomedical scientific work in the UK. EUPREN UK Working Party.

Science.gov (United States)

Owen, S; Thomas, C; West, P; Wolfensohn, S; Wood, M

1997-10-01

A Working Party of the UK group of European Primate Resources Network (EUPREN) considered primate supply for scientific work in the UK. Through a questionnaire, which achieved a very good response, it obtained details of primate use, sources and breeding in the UK and it put forward options to ensure that animal welfare is the best possible whilst ensuring continued supply. The questionnaire showed that contract research laboratories and pharmaceutical companies use about 80% of the 4233 primates used annually at the moment, with the rest accounted for by academic establishments and public sector laboratories. Fifty-four per cent are cynomolgus macaques (Macaca fascicularis), of which nearly 90% are captive-bred outside the European Union (EU), the remainder being bred in the UK. Nearly 90% of cynomolgus macaques are used by only five institutions. Thirty-seven per cent of primates used are marmosets (Callithrix jacchus jacchus), all of which are bred in the UK. Most of the rest are rhesus macaques (Macaca mulatta), about half of which are captive-bred outside the EU, the other half being bred in the UK. Overall primate use has increased from about 3000 per year in 1990 and users predict that requirements for all species except baboons (Papio sp.) will be maintained or increase. Marmoset breeding in the UK is already closely matched to use, and it could be increased reasonably easily if necessary. Some of the existing breeding centres of macaques in the UK would be prepared to consider expanding to supply others, although investment and imported breeding stock would be needed and it is likely that a large investment would be needed to breed a significant fraction of the macaque use in the UK. A further problem is that the users of only about 10% of the cynomolgus macaques said that they could replace this species by rhesus macaques, which are easier to breed in the UK. The questionnaire showed that much of the use of macaques would be transferred to other countries

Beyond shareholder primacy? Reflections on the trajectory of UK corporate governance.

Core institutions of UK corporate governance, in particular the City Code on Takeovers and Mergers, the Combined Code on Corporate Governance and the law on directors’ duties, are strongly orientated towards the norm of shareholder primacy. Beyond the core, however, stakeholder interests are better represented, in particular at the intersection of insolvency and employment law. This reflects the influence of European Community laws on information and consultation of employees. In addition, th...

To determine the incidence, risk factors, and appropriateness of differing guidelines in developed nations for screening for retinopathy of prematurity (ROP) in a single nursery in a large urban city in southern Turkey. The records of 260 premature infants born ≤34 weeks in a single tertiary unit were retrospectively reviewed for ROP risk factors and diagnosis. Applicability of UK and US criteria were assessed by the use of receiver operating characteristic curves. ROP of any stage was present in 60 infants (23%); ROP requiring treatment was seen in 30 (11.5%). Univariate analysis showed a significant relationship among the following factors: gestational age, birth weight, total duration of supplemental oxygen, duration of mechanical ventilation, respiratory distress syndrome, anemia, and intraventricular hemorrhage (p < 0.0001). Multiple logistic regression analysis showed gestational age (p = 0.039), birth weight (p = 0.05), respiratory distress syndrome (p = 0.05), and anemia (p = 0.004) as independent predictors of ROP requiring treatment. Area under curve for gestational age alone for diagnosing stage 2 or greater ROP was 0.824 ± 0.03 (p = 0.0001) and for birth weight alone was 0.808 ± 0.03 (p = 0.0001). UK screening criteria detected all stage 2 and greater ROP; US screening criteria missed 2 infants with stage 2 ROP but detected all treatment-requiring disease. Adoption of these screening criteria would have reduced unnecessary examinations by either 21% (UK) or 37% (US). UK and US criteria improved the detection accuracy for ROP requiring treatment in Turkey and should be studied for other developing nations.

Black carbon aerosol mixing state, organic aerosols and aerosol optical properties over the UK

McMeeking, G. R.; Morgan, W. T.; Flynn, M.; Highwood, E. J.; Turnbull, K.; Haywood, J.; Coe, H.

Black carbon (BC) aerosols absorb sunlight thereby leading to a positive radiative forcing and a warming of climate and can also impact human health through their impact on the respiratory system. The state of mixing of BC with other aerosol species, particularly the degree of internal/external mixing, has been highlighted as a major uncertainty in assessing its radiative forcing and hence its climate impact, but few in situ observations of mixing state exist. We present airborne single particle soot photometer (SP2) measurements of refractory BC (rBC) mass concentrations and mixing state coupled with aerosol composition and optical properties measured in urban plumes and regional pollution over the UK. All data were obtained using instrumentation flown on the UK's BAe-146-301 large Atmospheric Research Aircraft (ARA) operated by the Facility for Airborne Atmospheric Measurements (FAAM). We measured sub-micron aerosol composition using an aerosol mass spectrometer (AMS) and used positive matrix factorization to separate hydrocarbon-like (HOA) and oxygenated organic aerosols (OOA). We found a higher number fraction of thickly coated rBC particles in air masses with large OOA relative to HOA, higher ozone-to-nitrogen oxides (NOx) ratios and large concentrations of total sub-micron aerosol mass relative to rBC mass concentrations. The more ozone- and OOA-rich air masses were associated with transport from continental Europe, while plumes from UK cities had higher HOA and NOx and fewer thickly coated rBC particles. We did not observe any significant change in the rBC mass absorption efficiency calculated from rBC mass and light absorption coefficients measured by a particle soot absorption photometer despite observing significant changes in aerosol composition and rBC mixing state. The contributions of light scattering and absorption to total extinction (quantified by the single scattering albedo; SSA) did change for different air masses, with lower SSA observed in

UK wants more revenue from North Sea oil

Energy Technology Data Exchange (ETDEWEB)

1973-03-09

The first report from the Committee of Public Accounts of the UK Parliament on North Sea gas and oil has revealed a situation under which the UK Exchequer apparently does not receive cash intake comparable to the Exchequers of other oil producing countries. So important are these findings that some of them are presented so that the industry at large, and particularly those engaged in North Sea exploration and production, will be aware of the UK situation. Recomendations are made that the government should take action substantially to improve the effective tax yield from operations on the continental shelf, and should consider among other methods the possibility of imposing a system of quantity taxation.

Renewable energy policy in the UK 1990-2003

International Nuclear Information System (INIS)

Mitchell, Catherine; Connor, Peter

2004-01-01

The UK's renewable energy policy has been characterised by opportunism, cost-limiting caps and continuous adjustments resulting from a lack of clarity of goals. Renewable electricity has had a specific delivery mechanism in place since 1990. The Non-Fossil Fuel Obligation (NFFO) did not deliver deployment; did not create mentors; did not promote diversity; was focussed on electricity and was generally beneficial only to large companies. A new support mechanism, the Renewable Obligation, began in April 2002. This may result in more deployment than the NFFO, but is also beneficial to electricity-generating technologies and large, established companies only. The UK Government published a visionary energy policy in early 2003 placing the UK on a path to cutting carbon dioxide emissions by 60% in 2050. This paper argues that unless the Government 'learns' from it's past results, mistakes and difficulties, clarifies the reasons for supporting renewable energy and then follows through with a focussed policy aimed at delivery, diversity and the creation of mentors, it is likely to be no more successful than the previous 13 years of renewable policy

Digital Archiving of People Flow by Recycling Large-Scale Social Survey Data of Developing Cities

Data on people flow has become increasingly important in the field of business, including the areas of marketing and public services. Although mobile phones enable a person's position to be located to a certain degree, it is a challenge to acquire sufficient data from people with mobile phones. In order to grasp people flow in its entirety, it is important to establish a practical method of reconstructing people flow from various kinds of existing fragmentary spatio-temporal data such as social survey data. For example, despite typical Person Trip Survey Data collected by the public sector showing the fragmentary spatio-temporal positions accessed, the data are attractive given the sufficiently large sample size to estimate the entire flow of people. In this study, we apply our proposed basic method to Japan International Cooperation Agency (JICA) PT data pertaining to developing cities around the world, and we propose some correction methods to resolve the difficulties in applying it to many cities and stably to infrastructure data.

Financing the UK power sector: Is the money available?

International Nuclear Information System (INIS)

Blyth, William; McCarthy, Rory; Gross, Robert

2015-01-01

The UK power generation sector faces a major new round of investment: the coincidence of asset retiring and ambitious goals for decarbonisation is not unique, but is particularly acute in the UK. The UK government has put in place a raft of new policies that seek to promote new, low carbon investment and ensure security of supply. The traditional channel for financing the sector has been through large utility companies, but this now looks challenging for various reasons. The UK therefore offers an interesting case study on several counts; the scale of the challenge, effectiveness of new policies, and the availability of alternative finance. We find that the link between the finance sector and the electricity sector is not ‘broken’, but the flow of money to the sector is threatened by the current weakness of the utilities’ business model. This paper compares estimates of the scale of investment required in the UK with historical investment rates. It summarises contemporary finance industry views of conditions and trends, and potential policy interventions that might be needed to bridge the investment gap. The potential for channelling institutional investor funds directly into energy assets is reviewed. - Highlights: • Power investment need to scale up compared to historical trends, but is achievable. • Traditionally, low-cost finance has been through bonds and shares of large utilities. • Utilities are suffering high debt, reduced demand, and suppressed prices. • Policy interventions to scale-up investment are reviewed.

Larger scale tests of sodium fire extinguishment techniques have also been performed. Currently a programme of tests (SOFA) of large scale fires in the open to investigate the chemical and physical changes in the aerosol and its dispersion in the atmosphere are just beginning. The UK studies are intended to both assist in the development of prevention and mitigation systems for design base and beyond design base accidents in any building which contains sodium (or sodium potassium alloy) and also to provide methods for assessing the risks from such accidents.

Sizewell: UK power demand

International Nuclear Information System (INIS)

Anon.

1986-01-01

The Sizewell Inquiry was about whether the next power stations to be built in the UK should be nuclear or coal and, if nuclear, PWRs or AGRs. During the period of the Inquiry forecasts of demand for electricity were low. Now, however, it seems that the forecast demand is much increased. This uncertainty in demand and the wide regional variations are examined in some detail. Facts and figures on electricity sales (area by area) are presented. Also the minutes of supply lost per consumer per year. These show that security of supply is also a problem. It is also shown that the way electricity is used has changed. Whilst electricity generation has been changing to large-scale, centralised power stations the demand patterns may make smaller scale, quickly-constructed units more sensible. The questions considered at the Sizewell Inquiry may, indeed, no longer be the right ones. (UK)

The risk of hydraulic fracturing on public health in the UK and the UK's fracking legislation.

2015-01-01

Hydraulic fracturing to extract natural gas from shale rock is a new, rapidly expanding industry in the United States (US). However, there is concern that these operations could be having large negative impacts such as groundwater contamination, increased air pollution and seismic events. The United Kingdom (UK) is looking at the potential for emulating the success of 'shale gas' in the US. Differences in population density and geological conditions mean that the public health impacts recorded in the US cannot be directly extrapolated to the UK. There is limited academic literature available but findings suggest that the UK government is not fully recognising the inherent risks of hydraulic fracturing exposed by this literature. Government reports suggest a reliance on engineering solutions and better practice to overcome problems found in the US when evidence suggests that there are inherent risks and impacts that cannot be eliminated. This study applies US results to approximate the impact of one exposure pathway, inhalation of hydrocarbons by the public from operational air emissions over the 30 year lifetime of a well and finds that 7.2 extra cancer cases from exposure to air contamination would be expected in the UK if all test sites, approved test sites and test sites awaiting approval as of January 2015 went on to extract gas. In conclusion, limited assessment of the public health implications of hydraulic fracturing operations is available but the UK government appears to not be applying the precautionary principle to potentially significant legislation.

The seasonal trend of out-of-hospital coronary death (OHCD) and sudden cardiac death has been observed, but whether extreme temperature serves as a risk factor is rarely investigated. We therefore aimed to evaluate the impact of extreme temperatures on OHCDs in China. We obtained death records of 126,925 OHCDs from six large Chinese cities (Harbin, Beijing, Tianjin, Nanjing, Shanghai and Guangzhou) during the period 2009-2011. The short-term associations between extreme temperature and OHCDs were analysed with time-series methods in each city, using generalised additive Poisson regression models. We specified distributed lag non-linear models in studying the delayed effects of extreme temperature. We then applied Bayesian hierarchical models to combine the city-specific effect estimates. The associations between extreme temperature and OHCDs were almost U-shaped or J-shaped. The pooled relative risks (RRs) of extreme cold temperatures over the lags 0-14 days comparing the 1st and 25th centile temperatures were 1.49 (95% posterior interval (PI) 1.26-1.76); the pooled RRs of extreme hot temperatures comparing the 99th and 75th centile temperatures were 1.53 (95% PI 1.27-1.84) for OHCDs. The RRs of extreme temperature on OHCD were higher if the patients with coronary heart disease were old, male and less educated. This multicity epidemiological study suggested that both extreme cold and hot temperatures posed significant risks on OHCDs, and might have important public health implications for the prevention of OHCD or sudden cardiac death.

Adaptive Texture Synthesis for Large Scale City Modeling

Science.gov (United States)

Despine, G.; Colleu, T.

2015-02-01

Large scale city models textured with aerial images are well suited for bird-eye navigation but generally the image resolution does not allow pedestrian navigation. One solution to face this problem is to use high resolution terrestrial photos but it requires huge amount of manual work to remove occlusions. Another solution is to synthesize generic textures with a set of procedural rules and elementary patterns like bricks, roof tiles, doors and windows. This solution may give realistic textures but with no correlation to the ground truth. Instead of using pure procedural modelling we present a method to extract information from aerial images and adapt the texture synthesis to each building. We describe a workflow allowing the user to drive the information extraction and to select the appropriate texture patterns. We also emphasize the importance to organize the knowledge about elementary pattern in a texture catalogue allowing attaching physical information, semantic attributes and to execute selection requests. Roofs are processed according to the detected building material. Façades are first described in terms of principal colours, then opening positions are detected and some window features are computed. These features allow selecting the most appropriate patterns from the texture catalogue. We experimented this workflow on two samples with 20 cm and 5 cm resolution images. The roof texture synthesis and opening detection were successfully conducted on hundreds of buildings. The window characterization is still sensitive to the distortions inherent to the projection of aerial images onto the facades.

History of UK contribution to astronautics: Politics and government

Hicks CB, Colin

2009-12-01

In all developed countries, once it emerged from the amateur era, Space (and especially rocketry) moved on the public agenda because of its potential significance for both the civil and military policies of governments (coupled with its appetite for new money). In the UK the policy treatment of Space broadly paralleled that in other countries until the post-Empire trauma, the burn-out of the White-Hot Technological revolution of Harold Wilson, and the financial crises of the 1970s exhausted the public appetite for large scale publicly funded projects in high technology. The culmination for Space of these pressures came in 1986-1987 when the UK rejected the emerging international consensus and, almost alone, stayed outside the manned space commitments which developed into the International Space Station. In this paper, Colin Hicks will review the UK political developments which led up to the 1986-1987 decision and how the politics and organisation of UK space activity have developed since then to the point where in 2008 a major government review of the UK involvement in manned space was commissioned.

Economic Effects of Migration from Poland to the UK

2017-08-01

Full Text Available Considering that large numbers of the EU-8 immigrants was a strong argument for the Brexit, the objective of this paper is to assess some economic effects of migration from Poland to the UK for both countries. Intensive emigration of the Poles to the UK since 2004 negatively affected Poland’s economic growth in the long run, but it also reduced tensions at the labour market by decreasing the unemployment rate. On the other hand, the increase in Polish immigrants in the UK did not significantly affect economic growth and unemployment rate in the destination country in the short run in the period 2004-2015. A significance influence was observed only in the long run, when the UK economic growth decreased, but the pressures on the labour market significantly reduced. From these empirical findings, some policy recommendations are required for both countries: for Poland, migration policies to promote the return of migrants and more efficient utilization of labour force, while for the UK – shaping a more flexible labour market.

In this talk we will describe the development and current status of the UK Earth System Model (UKESM). This project is a NERC/Met Office collaboration and has two objectives; to develop and apply a world-leading Earth System Model, and to grow a community of UK Earth System Model scientists. We are building numerical models that include all the key components of the global climate system, and contain the important process interactions between global biogeochemistry, atmospheric chemistry and the physical climate system. UKESM will be used to make key CMIP6 simulations as well as long-time (e.g. millennium) simulations, large ensemble experiments and investigating a range of future carbon emission scenarios.

The ecological impact of city lighting scenarios: exploring gap crossing thresholds for urban bats.

Science.gov (United States)

Hale, James D; Fairbrass, Alison J; Matthews, Thomas J; Davies, Gemma; Sadler, Jon P

2015-02-02

As the global population urbanizes, dramatic changes are expected in city lighting and the urban form, which may threaten the functioning of urban ecosystems and the services they deliver. However, little is known about the ecological impact of lighting in different urban contexts. Movement is an important ecological process that can be disrupted by artificial lighting. We explored the impact of lighting on gap crossing for Pipistrellus pipistrellus, a species of bat (Chiroptera) common within UK cities. We aimed to determine whether the probability of crossing gaps in tree cover varied with crossing distance and lighting level, through stratified field surveys. We then used the resulting data on barrier thresholds to model the landscape resistance due to lighting across an entire city and explored the potential impact of scenarios for future changes to street lighting. The level of illumination required to create a barrier effect reduced as crossing distance increased. For those gaps where crossing was recorded, bats selected the darker parts of gaps. Heavily built parts of the case study city were associated with large and brightly lit gaps, and spatial models indicate movement would be highly restricted in these areas. Under a scenario for brighter street lighting, the area of accessible land cover was further reduced in heavily built parts of the city. We believe that this is the first study to demonstrate how lighting may create resistance to species movement throughout an entire city. That connectivity in urban areas is being disrupted for a relatively common species raises questions about the impacts on less tolerant groups and the resilience of bat communities in urban centres. However, this mechanistic approach raises the possibility that some ecological function could be restored in these areas through the strategic dimming of lighting and narrowing of gaps. © 2015 The Authors.

We have previously found high rates of poor iron and folate status in women who had delivered a low birthweight baby (LBW) in an ethnically diverse inner-city area of the UK. However, little was known of the nutritional status in the local general obstetric population. We therefore investigated biochemical measures of nutritional status in the first trimester of the first pregnancy. Routine blood samples collected at the antenatal booking clinic were analysed for haemoglobin (Hb), serum ferritin, red cell folate (RCF) (n = 100) and erythrocyte transketolase activation coefficient (ETKAC) for thiamin status (n = 90). We found 9% of women in our sample had a low Hb level, 10% had a low serum ferritin and only one had a low RCF. This is a substantially lower number of women with biochemical deficiencies than we found previously in women three months after delivering a LBW baby. However, 34% had low thiamin status. Thiamin status was negatively correlated with gestational age at birth (r = -0.407, p nutritional status were observed between ethnic and socio-economic groups. Hb levels differed between ethnic (p = 0.001) and socio-economic groups (p = 0.02), with Africans and women in manual occupations/unwaged having the lowest Hb levels. RCF levels also differed between groups (p nutrition particularly in ethnic minorities and low income groups who are most at risk of adverse birth outcomes such as LBW.

Of the large European wind energy markets, that of the UK is uniquely dominated by imported technology. An indigenous manufacturing base is desirable for strategic reasons, and to create employment and export opportunities. Analysis of the wind energy policies of other countries indicates the factors required to stimulate local manufacture. This paper examines how UK wind energy policy may be shaped for this purpose, taking account of the lessons learned under NFFO/SRO, and elsewhere in Europe. (Author)

DIGITAL ARCHIVING OF PEOPLE FLOW BY RECYCLING LARGE-SCALE SOCIAL SURVEY DATA OF DEVELOPING CITIES

Directory of Open Access Journals (Sweden)

2012-07-01

Full Text Available Data on people flow has become increasingly important in the field of business, including the areas of marketing and public services. Although mobile phones enable a person's position to be located to a certain degree, it is a challenge to acquire sufficient data from people with mobile phones. In order to grasp people flow in its entirety, it is important to establish a practical method of reconstructing people flow from various kinds of existing fragmentary spatio-temporal data such as social survey data. For example, despite typical Person Trip Survey Data collected by the public sector showing the fragmentary spatio-temporal positions accessed, the data are attractive given the sufficiently large sample size to estimate the entire flow of people. In this study, we apply our proposed basic method to Japan International Cooperation Agency (JICA PT data pertaining to developing cities around the world, and we propose some correction methods to resolve the difficulties in applying it to many cities and stably to infrastructure data.

Water availability and vulnerability of 225 large cities in the United States

Padowski, Julie C.; Jawitz, James W.

2012-12-01

This study presents a quantitative national assessment of urban water availability and vulnerability for 225 U.S. cities with population greater than 100,000. Here, the urban assessments account for not only renewable water flows, but also the extracted, imported, and stored water that urban systems access through constructed infrastructure. These sources represent important hydraulic components of the urban water supply, yet are typically excluded from water scarcity assessments. Results from this hydraulic-based assessment were compared to those obtained using a more conventional method that estimates scarcity solely based on local renewable flows. The inclusion of hydraulic components increased the mean availability to cities, leading to a significantly lower portion of the total U.S. population considered "at risk" for water scarcity (17%) than that obtained from the runoff method (47%). Water vulnerability was determined based on low-flow conditions, and smaller differences were found for this metric between at-risk populations using the runoff (66%) and hydraulic-based (54%) methods. The large increase in the susceptible population between the scarcity measures evaluated using the hydraulic method may better reconcile the seeming contradiction in the United States between perceptions of natural water abundance and widespread water scarcity. Additionally, urban vulnerability measures developed here were validated using a media text analysis. Vulnerability assessments that included hydraulic components were found to correlate with the frequency of urban water scarcity reports in the popular press while runoff-based measures showed no significant correlation, suggesting that hydraulic-based assessments provide better context for understanding the nature and severity of urban water scarcity issues.

Ventilation and Air Quality in City Blocks Using Large-Eddy Simulation—Urban Planning Perspective

Directory of Open Access Journals (Sweden)

Mona Kurppa

2018-02-01

Full Text Available Buildings and vegetation alter the wind and pollutant transport in urban environments. This comparative study investigates the role of orientation and shape of perimeter blocks on the dispersion and ventilation of traffic-related air pollutants, and the street-level concentrations along a planned city boulevard. A large-eddy simulation (LES model PALM is employed over a highly detailed representation of the urban domain including street trees and forested areas. Air pollutants are represented by massless and passive particles (non-reactive gases, which are released with traffic-related emission rates. High-resolution simulations for four different city-block-structures are conducted over a 8.2 km 2 domain under two contrasting inflow conditions with neutral and stable atmospheric stratification corresponding the general and wintry meteorological conditions. Variation in building height together with multiple cross streets along the boulevard improves ventilation, resulting in 7–9% lower mean concentrations at pedestrian level. The impact of smaller scale variability in building shape was negligible. Street trees further complicate the flow and dispersion. Notwithstanding the surface roughness, atmospheric stability controls the concentration levels with higher values under stably stratified inflow. Little traffic emissions are transported to courtyards. The results provide urban planners direct information to reduce air pollution by proper structural layout of perimeter blocks.

Large differences in publicly visible health behaviours across two neighbourhoods of the same city.

Directory of Open Access Journals (Sweden)

Daniel Nettle

Full Text Available BACKGROUND: There are socioeconomic disparities in the likelihood of adopting unhealthy behaviours, and success at giving them up. This may be in part because people living in deprived areas are exposed to greater rates of unhealthy behaviour amongst those living around them. Conventional self-report surveys do not capture these differences in exposure, and more ethological methods are required in order to do so. METHODOLOGY/PRINCIPAL FINDINGS: We performed 12 hours of direct behavioural observation in the streets of two neighbourhoods of the same city which were similar in most regards, except that one was much more socioeconomically deprived than the other. There were large differences in the publicly visible health behaviours observed. In the deprived neighbourhood, we observed 266 more adults smoking (rate ratio 3.44, 53 more adults drinking alcohol (rate ratio not calculable, and 38 fewer adults running (rate ratio 0.23, than in the affluent neighbourhood. We used data from the Health Survey for England to calculate the differences we ought to expect to have seen given the individual-level socioeconomic characteristics of the residents. The observed disparities between the two neighbourhoods were considerably greater than this null model predicted. There were also different patterns of smoking in proximity to children in the two neighbourhoods. CONCLUSIONS/SIGNIFICANCE: The differences in observed smoking, drinking alcohol, and physical activity between these two neighbourhoods of the same city are strikingly large, and for smoking and running, their magnitude suggests substantial area effects above and beyond the compositional differences between the neighbourhoods. Because of these differences, individuals residing in deprived areas are exposed to substantially more smoking and public drinking, and less physical activity, as they go about their daily lives, than their affluent peers. This may have important implications for the initiation

2011-01-01

This paper presents findings on expert perceptions of uncertainty in carbon capture and storage (CCS) technology and policy in the UK, through survey data and semi-structured interviews with 19 individual participants. Experts were interviewed in industry, research, and non-governmental organisations (NGOs) in the summer of 2009 and were asked to comment on a range of technical processes as well as policy concerns. The survey revealed that perceptions of the technology conform to a 'certainty trough' with users expressing the lowest level of uncertainty, and outsiders expressing the highest level of uncertainty. The interviews revealed that experts express certitude in the prospects for deploying large-scale CCS technology in the UK, all the while questioning several underlying technical and policy premises that are necessary to ensure this goal. - Highlights: → Expert perceptions of CCS in the UK are reported in interviews and a survey. → Surveyed perceptions conform to a 'certainty trough'. → Experts express certitude in prospect of large-scale CCS deployment in the UK. → Experts state that several technical and policy premises are necessary to ensure this goal. → Prospect of large-scale CCS deployment is observed to be highly belief-based.

Using tradeable permits to achieve sustainability in the world`s large cities. Policy design issues and efficiency conditions for controlling vehicle emissions, congestion and urban decentralization with an application to Mexico City

Energy Technology Data Exchange (ETDEWEB)

Goddard, H.C. [Instituto Tecnologico Autonomo de Mexico, Mexico City (Mexico)

1997-07-01

Many large cities in the world have serious ground level ozone problems, largely the product of vehicular emissions and thus the argued unsustainability of current urban growth patterns is frequently blamed on unrestricted private vehicle use. This article reviews Mexico City`s experience with vehicle use restrictions as an emissions control program and develops the conditions for optimal quantitative restrictions on vehicle use and for complementary abatement technologies. The stochastic nature of air pollution outcomes is modelled explicitly in both the static and dynamic formulations of the control problem, in which for the first time in the literature the use of tradeable vehicle use permits is proposed as a cost-effective complement to technological abatement for mobile emissions control. This control regime gives the authorities a broader and more flexible set of instruments with which to deal more effectively with vehicle emissions, and with seasonal and stochastic variation of air quality outcomes. The market in tradeable vehicle use permits would be very competitive with low transactions costs. This control policy would have very favorable impacts on air quality, vehicle congestion and on urban form and development. Given the general political resistance to environmental taxes, this program could constitute a workable and politically palatable set of policies for controlling greenhouse gas emissions from the transport sector. 7 figs., 1 appendix, 23 refs.

Environmental issues of an intermediate city

International Nuclear Information System (INIS)

Ahmad, N.

2005-01-01

Our urban centers present a unique dimension of environmental problems. They are at one and the same time, enormous consumers of natural resources and produces of waste and pollution. In this respect intermediate cities and small towns appear to be more vulnerable to natural catastrophes and ecological accidents caused by human factors. While in large cities there exist pressure groups which attain government attention for the solution of their problems and have well equipped municipalities. However, a vast majority of the population lives in rural areas and depends upon medium sized cities and towns for access to services. These cities and towns form the pivot of economic, social, cultural and political life for a large part of the population. Therefore, it deserves more attention than bigger ones. This paper explores local people perception about urban environmental problems exist in the city. Attempts are also made to shape and guide municipality efforts to overcome such problems with available resources. (author)

Big data, smart cities and city planning.

Batty, Michael

2013-11-01

I define big data with respect to its size but pay particular attention to the fact that the data I am referring to is urban data, that is, data for cities that are invariably tagged to space and time. I argue that this sort of data are largely being streamed from sensors, and this represents a sea change in the kinds of data that we have about what happens where and when in cities. I describe how the growth of big data is shifting the emphasis from longer term strategic planning to short-term thinking about how cities function and can be managed, although with the possibility that over much longer periods of time, this kind of big data will become a source for information about every time horizon. By way of conclusion, I illustrate the need for new theory and analysis with respect to 6 months of smart travel card data of individual trips on Greater London's public transport systems.

Oil and gas operational and policy issues in the UK

International Nuclear Information System (INIS)

Howard, D.

1992-01-01

The method of arriving at monthly values under Schedule 3 OTA 1975 applies to all oil which can include LPG and condensate as well as crude oil and gas. The majority of crude oil is now sold spot and in 1987 the method of arriving at monthly values was amended better to reflect this aspect of the crude oil market. The UK gas market was such that the proceeds of sale of large amounts of natural gas were exempt from PRT under Section 10 OTA 1975 and very little gas was disposed of other than at arms length to British Gas. British Gas no longer buys virtually all gas produced from the UK Continental Shelf and neither does it sell all the gas used by UK customers. The use of natural gas to generate electricity has opened up a new market for UK landed gas. How do these changes affect gas valuation.?. (Author)

Supervised Outlier Detection in Large-Scale Mvs Point Clouds for 3d City Modeling Applications

Science.gov (United States)

Stucker, C.; Richard, A.; Wegner, J. D.; Schindler, K.

2018-05-01

We propose to use a discriminative classifier for outlier detection in large-scale point clouds of cities generated via multi-view stereo (MVS) from densely acquired images. What makes outlier removal hard are varying distributions of inliers and outliers across a scene. Heuristic outlier removal using a specific feature that encodes point distribution often delivers unsatisfying results. Although most outliers can be identified correctly (high recall), many inliers are erroneously removed (low precision), too. This aggravates object 3D reconstruction due to missing data. We thus propose to discriminatively learn class-specific distributions directly from the data to achieve high precision. We apply a standard Random Forest classifier that infers a binary label (inlier or outlier) for each 3D point in the raw, unfiltered point cloud and test two approaches for training. In the first, non-semantic approach, features are extracted without considering the semantic interpretation of the 3D points. The trained model approximates the average distribution of inliers and outliers across all semantic classes. Second, semantic interpretation is incorporated into the learning process, i.e. we train separate inlieroutlier classifiers per semantic class (building facades, roof, ground, vegetation, fields, and water). Performance of learned filtering is evaluated on several large SfM point clouds of cities. We find that results confirm our underlying assumption that discriminatively learning inlier-outlier distributions does improve precision over global heuristics by up to ≍ 12 percent points. Moreover, semantically informed filtering that models class-specific distributions further improves precision by up to ≍ 10 percent points, being able to remove very isolated building, roof, and water points while preserving inliers on building facades and vegetation.

Quality of life declines in big and growing cities. Poverty in cities.

Science.gov (United States)

Harel, K

1997-01-01

The quality of life in developing countries during the first couple of decades after the Second World War was higher in cities than in small towns and villages. However, the relative advantage of city dwellers in developing countries has declined since the 1970s, with high-growth rate cities experiencing a more severe decline. Infant mortality levels in Latin America and sub-Saharan Africa in the 1990s are as high in large cities as in the smallest towns and villages. In most developing regions, big city residents are increasingly disadvantaged, such that researchers and policymakers can no longer assume that the quality of life in urban areas is better than in rural areas. The urban transformation of the developing world is similar to the 19th century urbanization of now-developed countries, but today many more people are crowding into far bigger cities. Using survey information from 43 countries representing 63% of the developing world's urban population outside of China and India, Martin Brockerhoff of the Population Council and Ellen Brennan of the UN Population Division found that rapid population growth and big size have overwhelmed the capacity of cities to provide essential goods and services.

Resilience improvements to UK nuclear power plants

International Nuclear Information System (INIS)

Pepper, Kevin

2015-01-01

Following the events at Fukushima, the Office for Nuclear Regulation (ONR), the UK nuclear safety regulator, undertook a series of reviews into the resilience of UK nuclear power plants to severe events. These reviews highlighted a number of areas in relation to electrical infrastructure where it considered licensees should review their arrangements, considering both onsite and offsite infrastructure as well as the ability to recover following a complete loss of site infrastructure. In response, UK licensees have been exploring four parallel approaches to improving the resilience for each of their sites. Firstly, through modifications on-site such as enhancements to the installed diesel generators and related systems. Secondly through improvements to the resilience of essential instrumentation to Station Black Out events. Thirdly, through the provision of off-site backup equipment that can be deployed to any site following a severe event. Finally, the provision of event qualified connection points on site to enable timely restoration of long term essential electrical supplies and cooling to key systems. This last item gives a central focus to the issues of switchboard availability and the resilience of the whole network to large potentially common cause internal and external hazards. This paper will discuss the electrically related findings of the ONR reviews, explore the reasoning behind those decisions, and describe the approaches being taken by UK licensees. (authors)

To describe the current status of the decision-making process with regard to the use of contraceptive methods among internal migrant workers in three large Chinese cities. A total of 4313 sexually active internal migrant workers were recruited in Beijing, Shanghai, and Chengdu. Information on contraceptive use was collected by means of questionnaires. Contraceptive prevalence was 86% among unmarried sexually active migrant workers and 91% among married workers. The main contraceptive methods used by married migrants were the intrauterine device (51%), condoms (25%) and female/male sterilisation (17%); the main methods resorted to by unmarried, sexually active migrants were condoms (74%) and oral contraceptives (11%). The contraceptive method applied by 20% of married respondents had been selected by other people, without they themselves having their share in an informed choice. Adopting the contraceptive decisions made by others was associated with being a married migrant, a construction or service worker, a rural-urban migrant, a migrant living in collective or rented rooms, or a migrant with more children. Many internal migrants in these large cities did not choose their contraceptive method on their own. Efforts enabling and encouraging migrants to make informed choices are needed.

Developing wind energy for the UK

Energy Technology Data Exchange (ETDEWEB)

Rand, Marcus [Open Univ., Milton Keynes (GB). Faculty of Technology

1990-01-01

There is now emerging a consensus that the sensitive development of renewable sources of energy, and in particular wind energy, is going to be of major environmental significance for the UK. Primarily, renewable sources of energy can act as a means of combating the Greenhouse Effect and of reducing the other environmental impacts of conventional energy technology, including the build-up of radioactive waste and the damaging emissions from fossil fuelled power stations. The UK has a large natural potential for harnessing energy from the wind (between 20% and 200% of our current electrical requirements). This potential is beginning to be tapped. Wind energy is now in a position where it can take advantage of the profound changes taking place in the form of the privatisation of the Electricity Supply Industry. In other countries wind energy has developed successfully. (author).

MNCs in Denmark and the UK

Multinational companies (MNCs) have more opportunities than ever to forum shop and choose between different market systems - including different industrial relations (IR) systems. When an MNC choose to engage in a certain country, it also becomes an actor in the country's labor market system. MNCs...... are often quite large companies, and hence they can become significant players, potentially affecting the existing balances between the social partners. The question is whether MNCs adapt to the host country's labor market system (host country effect) - or if they seek in various ways to change the host...... to determine the employment relations. Quite the opposite to the UK, where trade unions are weak and where collective bargaining is far less widespread. Further analyses show that MNCs originating from liberal market economies (especially the US) acts differently in the two countries; in the UK they tend...

Vatican City.

1984-11-01

Vatican City, the administrative and spiritual capital of the Roman catholic Church, has a population of 1000. Citizenship is generally accorded only to those who reside in Vatican City for reasons of office of employment. Supreme legislative, executive, and judicial power is currentily exercised by Pope John Paul II, the 1st non-italian pope in 5 centuries. The State of Vatican City is recognized by many nations as an independent sovereign state under the temporal jurisdiction of the Pope. By 1984, 108 countries had established diplomatic relations with the Holy See, most of which are not Roman Catholic. Third World countries comprise a large proportion of countries that have recently established relations with the Holy See. The US re-established relations with the Vatican in 1984 and there is frequent contact and consultation between the 2 states on key international issues.

2013-07-01

Recent studies examining the relationship between family income and child health in the UK have produced mixed findings. We re-examine the income gradient in child general health and its evolution with child age in this country, using a very large sample of British children. We find that there is no correlation between income and child general health at ages 0-1, that the gradient emerges around age 2 and is constant from age 2 to age 17. In addition, we show that the gradient remains large and significant when we reduce the endogeneity of income. Furthermore, our results indicate that the gradient in general health reflects a greater prevalence of chronic conditions among low-income children and a greater severity of these conditions. Taken together, these findings suggest that income does matter for child health in the UK and may play a role in the intergenerational transmission of socioeconomic status.

Few multicity studies have been conducted to investigate the acute health effects of cold and hot temperatures in China. We aimed to examine the relationship between temperature and daily mortality in 17 large Chinese cities. We first calculated city-specific effect of temperature using time-series regression models combined with distributed lag nonlinear models; then we pooled the city-specific estimates with the Bayesian hierarchical models. The cold effects lasted longer than the hot effects. For the cold effects, a 1 °C decrease from the 25th to 1st percentiles of temperature over lags 0-14 days was associated with increases of 1.69% [95% posterior intervals (PI): 1.01%, 2.36%], 2.49% (95% PI: 1.53%, 3.46%) and 1.60% (95% PI: 0.32%, 2.87%) in total, cardiovascular and respiratory mortality, respectively. For the hot effects, a 1 °C increase from the 75th to 99th percentiles of temperature was associated with corresponding increases of 2.83% (95% PI: 1.42%, 4.24%), 3.02% (95% PI: 1.33%, 4.71%) and 4.64% (95% PI: 1.96%, 7.31%). The latitudes, number of air conditioning per household and disposable income per capita were significant modifiers for cold effects; the proportion of the elderly was a significant modifier for hot effects. This largest epidemiological study of temperature to date in China suggested that both cold and hot temperatures were associated with increased mortality. Our findings may have important implications for the public health policies in China. Copyright © 2014 Elsevier Inc. All rights reserved.

Objective To report on the career intentions, three years after qualification, of 12 national cohorts of UK-trained doctors who qualified between 1974 and 2012, and, specifically, to compare recent UK medical graduates' intentions to work in medicine in the UK with earlier graduates. Design Questionnaire surveys of cohorts of UK medical graduates defined by year of graduation. Setting UK. Participants 30,272 UK medical graduates. Main outcome measures Stated level of intention to pursue a long-term career in medicine in the UK. Results The response rate was 62% (30,272/48,927). We examined responses to the question ' Apart from temporary visits abroad, do you intend to practise medicine in the United Kingdom for the foreseeable future?' Of doctors from UK homes, 90% had specified that they would 'definitely or probably' practise medicine in the UK in the surveys of 1977-1986, 81% in 1996-2011 and 64% in 2015. Those who said that they would probably or definitely not practise medicine in the UK comprised 5% in 1977-1986, 8% in 1996-2011 and 15% in 2015. Most who were not definite about a future career in UK medicine indicated that they would wish to practise medicine outside the UK rather than to leave medicine. Conclusions The wish to remain in UK medical practice in the 2015 survey was unprecedentedly low in this unique series of 40 years of surveys.

Quantification of fossil fuel emissions, however, is one piece in a larger conception of cities as complex dynamic socio-technological systems and the Hestia effort is at the very beginning stages of connecting to the large community of research approaching cities from other perspectives and utilizing other tools. Through analysis of the three cities for which we have quantified fossil fuel CO2 emissions and recognition of the current threads emerging in urban research, we are attempting to offer insight into understanding cities via the mechanistic quantification of energy and CO2 emissions.

Schizophrenia and city life.

Lewis, G; David, A; Andréasson, S; Allebeck, P

1992-07-18

Prevalence of schizophrenia and rates of first admission to hospital for this disorder are higher in most modern industrialised cities, and in urban compared with rural areas. The "geographical drift" hypothesis (ie, most schizophrenics tend to drift into city areas because of their illness or its prodrome) has remained largely unchallenged. We have investigated the association between place of upbringing and the incidence of schizophrenia with data from a cohort of 49,191 male Swedish conscripts linked to the Swedish National Register of Psychiatric Care. The incidence of schizophrenia was 1.65 times higher (95% confidence interval 1.19-2.28) among men brought up in cities than in those who had had a rural upbringing. The association persisted despite adjustment for other factors associated with city life such as cannabis use, parental divorce, and family history of psychiatric disorder. This finding cannot be explained by the widely held notion that people with schizophrenia drift into cities at the beginning of their illness. We conclude that undetermined environmental factors found in cities increase the risk of schizophrenia.

Small cities face greater impact from automation

Sun, Lijun; Cebrian, Manuel; Rahwan, Iyad

2018-01-01

The city has proved to be the most successful form of human agglomeration and provides wide employment opportunities for its dwellers. As advances in robotics and artificial intelligence revive concerns about the impact of automation on jobs, a question looms: how will automation affect employment in cities? Here, we provide a comparative picture of the impact of automation across US urban areas. Small cities will undertake greater adjustments, such as worker displacement and job content substitutions. We demonstrate that large cities exhibit increased occupational and skill specialization due to increased abundance of managerial and technical professions. These occupations are not easily automatable, and, thus, reduce the potential impact of automation in large cities. Our results pass several robustness checks including potential errors in the estimation of occupational automation and subsampling of occupations. Our study provides the first empirical law connecting two societal forces: urban agglomeration and automation's impact on employment. PMID:29436514

Birth and death in cities in the developing world.

Science.gov (United States)

1995-06-01

City dwellers in Sub-Saharan Africa have increased roughly 600% in the last 35 years. Throughout the developing world, cities have expanded at a rate that has far outpaced rural population growth. Extensive data document lower fertility and mortality rates in cities than in rural regions. But slums, shantytowns, and squatters' settlements proliferate in many large cities. Martin Brockerhoff studies the reproductive and health consequences of urban growth, with an emphasis on maternal and child health. Brockerhoff reports that child mortality rates in large cities are highest among children born to mothers who recently migrated from rural areas or who live in low-quality housing. Children born in large cities have about a 30% higher risk of dying before they reach the age of 5 than those born in smaller cities. Despite this, children born to migrant mothers who have lived in a city for about a year have much better survival chances than children born in rural areas to nonmigrant mothers and children born to migrant mothers before or shortly after migration. Migration in developing countries as a whole has saved millions of children's lives. The apparent benefits experienced in the 1980s may not occur in the future, as cities continue to grow and municipal governments confront an overwhelming need for housing, jobs, and services. Another benefit is that fertility rates in African cities fell by about 1 birth per woman as a result of female migration from villages to towns in the 1980s and early 1990s. There will be an increasing need for donors and governments to concentrate family planning, reproductive health, child survival, and social services in cities, particularly in Sub-Saharan Africa, because there child mortality decline has been unexpectedly slow, overall fertility decline is not yet apparent in most countries, and levels of migration to cities are anticipated to remain high.

1983-01-01

Nuclear fuel reprocessing has been carried out on an industrial scale in the United Kingdom since 1952. Two large reprocessing plants have been constructed and operated at Windscale, Cumbria and two smaller specialized plants have been constructed and operated at Dounreay, Northern Scotland. At the present time, the second of the two Windscale plants is operating, and Government permission has been given for a third reprocessing plant to be built on that site. At Dounreay, one of the plants is operating in its original form, whilst the second is now operating in a modified form, reprocessing fuel from the prototype fast reactor. This chapter describes the development of nuclear fuel reprocessing in the UK, commencing with the research carried out in Canada immediately after the Second World War. A general explanation of the techniques of nuclear fuel reprocessing and of the equipment used is given. This is followed by a detailed description of the plants and processes installed and operated in the UK

UK energy policy ambition and UK energy modelling-fit for purpose?

International Nuclear Information System (INIS)

Strachan, Neil

2011-01-01

Aiming to lead amongst other G20 countries, the UK government has classified the twin energy policy priorities of decarbonisation and security of supply as a 'centennial challenge'. This viewpoint discusses the UK's capacity for energy modelling and scenario building as a critical underpinning of iterative decision making to meet these policy ambitions. From a nadir, over the last decade UK modelling expertise has been steadily built up. However extreme challenges remain in the level and consistency of funding of core model teams - critical to ensure a full scope of energy model types and hence insights, and in developing new state-of-the-art models to address evolving uncertainties. Meeting this challenge will facilitate a broad scope of types and geographical scale of UK's analytical tools to responsively deliver the evidence base for a range of public and private sector decision makers, and ensure that the UK contributes to global efforts to advance the field of energy-economic modelling. - Research highlights: → Energy modelling capacity is a critical underpinning for iterative energy policy making. → Full scope of energy models and analytical approaches is required. → Extreme challenges remain in consistent and sustainable funding of energy modelling teams. → National governments that lead in global energy policy also need to invest in modelling capacity.

Residential greenness and prevalence of major depressive disorders: a cross-sectional, observational, associational study of 94 879 adult UK Biobank participants

Directory of Open Access Journals (Sweden)

Chinmoy Sarkar, PhD

2018-04-01

Full Text Available Summary: Background: Increased urbanisation and the associated reduced contact of individuals with natural environments have led to a rise in mental disorders, including depression. Residential greenness, a fundamental component of urban design, has been shown to reduce the public health burden of mental disorders. The present study investigates the association between residential green exposure and prevalence of major depressive disorders using a large and diverse cross-sectional dataset from the UK Biobank. Methods: In this cross-sectional, observational, associational study, we used baseline data from the UK Biobank cohort of participants aged 37–73 years from across the UK. Environmental exposure data were derived from a modelled and linked built environment database. Residential greenness was assessed with a 0·5 m resolution Normalised Difference Vegetation Index, which is derived from spectral reflectance measurements in remotely sensed colour infrared data and measured within geocoded dwelling catchments. Other environment metrics included street-level movement density, terrain, and fine particulate exposures. A series of logistic models examined associations between residential greenness and odds of major depressive disorder after adjusting for activity-influencing environments and individual covariates. Findings: Of 122 993 participants with data on major depressive disorder, the study analytical sample comprised 94 879 (77·1% participants recruited across ten UK Biobank assessment centres between April 29, 2009, and Oct 1, 2010. A protective effect of greenness on depression was consistently observed, with 4·0% lower odds of major depressive disorder per interquartile increment in Normalised Difference Vegetation Index greenness (odds ratio 0·960, 95% CI 0·93–0·99; p=0·0044. Interaction analyses indicated that the beneficial effects of greenness were more pronounced among women, participants younger than 60 years, and

Modelling the long-range transport of secondary PM 10 to the UK

Science.gov (United States)

Malcolm, A. L.; Derwent, R. G.; Maryon, R. H.

The fine fraction of airborne particulate matter (PM 10) is known to be harmful to human health. In order to establish how current air quality standards can best be met now and in the future, it is necessary to understand the cause of PM 10 episodes. The UK Met Office's dispersion model, NAME, has been used to model hourly concentrations of sulphate aerosol for 1996 at a number of UK locations. The model output has been compared with measured values of PM 10 or sulphate aerosol at these sites and used to provide attribution information. In particular two large PM 10 episodes in March and July 1996 have been studied. The March episode has been shown to be the result of imported pollution from outside the UK, whereas the July case was dominated by UK emissions. This work highlights the need to consider trans-boundary pollution when setting air quality standards and when making policy decisions on emissions.

What is the prognosis of nitrogen losses from UK soils?

The UK’s high population density, intensive agriculture and relative short, unimpeded rivers mean that the UK is a known “hotspot” of fluvial nitrogen flux. Furthermore, it is known that the fluvial flux of nitrogen from the UK is increasing. This study estimates the release of nitrate from the UK terrestrial biosphere to understand this rising fluvial flux and i to assess the in-stream losses of nitrate, thusgiving an assessment of the fluvial component of the total nitrogen budget of UK. The approach taken by the study is to use an export coefficient model coupled with a description of mineralisation and immobilisation of nitrogen within soil reserves. The study applies the modelling approach to the whole of the UK from 1925 to 2007 using long term records of: land use (including - agricultural, forestry and urban uses); livestock; human population and atmospheric deposition. The study shows that: i) The flux of nitrate from the UK soils varied from 420 to 1463 Ktonnes N/yr with two peaks in the period since 1925, one in 1944 and one in 1967, the first is caused by mineralisation of soil organic matter following large-scale land use change in the Second World War, and the second is a multifactorial response to land use change and intensification. ii) The current trend in the release from soils is downward whilst the current fluvial flux at the tidal limit is upwards. With the current trends fluvial flux at the tidal limit will be greater than release from the soils of the UK, i.e. there will be net gain across the fluvial network. This apparent gain can be explained by the breakthrough of high nitrate groundwater into surface waters.

UK Biobank is a large prospective cohort study in the UK established by the Medical Research Council (MRC) and the Wellcome Trust to enable approved researchers to investigate the role of genetic factors, environmental exposures and lifestyle in the causes of major diseases of late and middle age. A wide range of phenotypic data has been collected at recruitment and has recently been enhanced by the UK Biobank Genotyping Project. All UK Biobank participants (500,000) have been genotyped on either the UK Biobank Axiom® Array or the Affymetrix UK BiLEVE Axiom® Array and the workflow for preparing samples for genotyping is described. The genetic data is hoped to provide further insight into the genetics of disease. All data, including the genetic data, is available for access to approved researchers. Data for two methods of DNA quantification (ultraviolet-visible spectroscopy [UV/Vis]) measured on the Trinean DropSense™ 96 and PicoGreen®) were compared by two laboratories (UK Biobank and Affymetrix). The sample processing workflow established at UK Biobank, for genotyping on the custom Affymetrix Axiom® array, resulted in high quality DNA (average DNA concentration 38.13 ng/μL, average 260/280 absorbance 1.91). The DNA generated high quality genotype data (average call rate 99.48% and pass rate 99.45%). The DNA concentration measured on the Trinean DropSense™ 96 at UK Biobank correlated well with DNA concentration measured by PicoGreen® at Affymetrix (r = 0.85). The UK Biobank Genotyping Project demonstrated that the high throughput DNA extraction protocol described generates high quality DNA suitable for genotyping on the Affymetrix Axiom array. The correlation between DNA concentration derived from UV/Vis and PicoGreen® quantification methods suggests, in large-scale genetic studies involving two laboratories, it may be possible to remove the DNA quantification step in one laboratory without affecting downstream analyses.

Full Text Available It has been a century since the first Garden Cities at Welwyn and Letchworth were founded and, in the eyes of many, we have entered the age of the Smart City. This commentary briefly reflects upon the origins of Ebenezer Howard’s vision in the slums of overcrowded, filthy London and the fire-traps of early 20th century Chicago before outlining some of the main contributing factors to its ultimate failure as an approach: the lack of a robust theory underpinning his ideas, a finance model which was unacceptable to the banks—leading to a compromise which robbed the more idealistic participants of any real power over their schemes—and finally, a dilution of Howard’s vision by architects who were more focused on population density than on social reform. A parallel is then drawn between the weaknesses which afflicted the Garden City vision, and those which afflict current Smart City visions, a loose agglomeration of ahistorical techno-utopian imaginaries, whose aims almost invariably include optimising various measures of efficiency using large-scale deployments of networked sensors and cameras, linked to monolithic control rooms from which our shared urban existence is overseen. The evolution (or perhaps more accurately: alteration of these concepts in response to criticism is then detailed, before some of the less well-known ideas which are now emerging are briefly discussed.

Modern cities and metropolitan areas all over the world face new management challenges in the 21st century primarily due to increasing demands on living standards by the urban population. These challenges range from climate change, pollution, transportation, and citizen engagement, to urban planning, and security threats. The primary goal of a Smart City is to counteract these problems and mitigate their effects by means of modern ICT to improve urban administration and infrastructure. Key id...

[The monster and the city].

Science.gov (United States)

Calvo Albizu, A

1996-01-01

"Negative aesthetic categories" and, specifically, the idea of monsters and monstrosity, are used in this discussion of urban phenomena and their relation to modern art. The reflection on monstrosity as a metaphor for the city draws upon such disparate sources as Greek philosophers, Freudian theory, and recent art criticism. It compares dictionary definitions of monster to a general concept of cities, judging the modern metropolis to be "excessively large or extraordinary," "disfigured and ugly," and even "cruel" and "perverse" as demonstrated in social pathologies such as terrorism that breed in cities. The relationship between monstrosity and the city is evident in a variety of artistic manifestations and can be seen in the work of planners, architects, and artists. The examination opens up promising areas for future research in greater depth.

Sustainability and Interest Group Participation in City Politics

Directory of Open Access Journals (Sweden)

Kent E. Portney

2013-05-01

Full Text Available Many cities across the United States have embraced programs aimed at achieving greater sustainability. This may seem surprising, particularly since adopting aggressive environmental protection programs is regarded by some as inimical to economic development. An alternative perspective is that in the modern city sustainability can be part of an economic development strategy. What is largely missing from the literature on sustainable cities’ policies and programs is systematic analysis of the political dynamics that seem to affect support for, and adoption and implementation of, local sustainability policies. To explore the actual behavior of cities with respect to sustainability and economic development policies, two original databases on 50 large U.S. cities are used. One source of data is composed of survey responses from city councilors, agency administrators, and leaders of local advocacy groups in each of these cities. The second database contains information as to what these 50 cities actually do in terms of sustainable programs and policies. In testing a series of hypotheses, findings suggest that: a high number of programs aimed at achieving sustainability is linked to the inclusion of environmental advocacy groups; that this relationship is not compromised by business advocacy; and that inclusion of environmental groups in policymaking seems to be supported, rather than impeded, by high rates of economic growth by the cities.

Cultural diversity training for UK healthcare professionals: a comprehensive nationwide cross-sectional survey.

Bentley, Paul; Jovanovic, Ana; Sharma, Pankaj

2008-10-01

Healthcare inequalities within the UK based on patients' ethnicity have been found over the last five years in a large number of medical specialties. One possible explanation for this lies in ignorance of ethnic minority healthcare needs among professionals. Cultural diversity programmes have been shown to improve patient outcomes including compliance, yet these are not as yet requirements for any UK healthcare professionals with the exception of psychiatrists. This paper documents the frequency, regional variation, characteristics and motivations for cultural diversity training through a questionnaire survey of the educational leads of every UK medical school, postgraduate deanery and schools of nursing, physiotherapy, occupational therapy, speech and language therapy, and pharmacy. The results showed a wide variation in teaching practices between healthcare professions and geographical regions. This study provides evidence for the need for national guidelines to incorporate cultural competency training by all UK healthcare professional training bodies.

UK public attitudes to the nuclear industry: the effect of the Sellafield visitor centre

Public support for the nuclear industry appears to be growing in the UK at a time when environmental awareness is also prominent. Perceived advantages from nuclear power range from conservation of scare fossil reserves through to maintaining a worldwide technical competitiveness. Within the UK, the Sellafield Visitors Centre has proved to be a large tourist attraction, as well as successfully presenting information in a form that is easy to understand. (author)

Hosting a mega-event is a costly activity of short duration. Still, cities frequently compete to become host of all types of events. This paper examines the effect of staging the largest and most important sporting event in the world, the Summer Olympic Games, on the host city. Applying a difference-in-differences methodology, we analyze the rates of population growth of Olympic cities, candidate cities and other large cities in host and candidate countries over the period from 1860 to 2010. ...

Carbon and environmental footprinting of low carbon UK electricity futures to 2050

International Nuclear Information System (INIS)

Alderson, Helen; Cranston, Gemma R.; Hammond, Geoffrey P.

2012-01-01

Electricity generation contributes a large proportion of the total greenhouse gas emissions in the United Kingdom (UK), due to the predominant use of fossil fuel (coal and natural gas) combustion for this purpose. A range of future UK energy scenarios has been employed to determine their resulting environmental and carbon footprints. Methodologies have been established to calculate these footprints for the UK electricity supply industry on both a historic timescale and in accordance with the three selected scenarios. The latter scenarios, developed by the UK SUPERGEN Consortium on ‘Highly Distributed Power Systems’ (HDPS), were characterised as ‘Business As Usual’ (BAU), ‘Low Carbon’ (LC) and ‘Deep Green’ (DG) futures, and yielded possible electricity demands out to 2050. It was found that the environmental footprint of the current power network is 41 million (M) global hectares (gha). If future trends follow a ‘Business As Usual’ scenario, then this footprint is observed to fall to about 25 Mgha in 2050. The LC scenario implies an extensive penetration of micro-generators in the home to satisfy heat and power demands. However, these energy requirements are minimised by way of improved insulation of the building fabric and other demand reduction measures. In contrast, the DG scenario presupposes a network where centralised renewable energy technologies – mainly large-scale onshore and offshore wind turbines - have an important role in the power generation. However, both the LC and DG scenarios were found to lead to footprints of less than 4 Mgha by 2050. These latter two scenarios were found to give rise to quite similar trajectories over the period 2010–2050. They are therefore more likely to reflect an effective transition pathway in terms of meeting the 2050 UK CO 2 reduction targets associated with decarbonisation of its power network. However, this appears unlikely to be achieved by 2030–2040 as advocated by the UK Government

Water-quality assessment of the largely urban blue river basin, Metropolitan Kansas City, USA, 1998 to 2007

From 1998 through 2007, over 750 surface-water or bed-sediment samples in the Blue River Basin - a largely urban basin in metropolitan Kansas City - were analyzed for more than 100 anthropogenic compounds. Compounds analyzed included nutrients, fecal-indicator bacteria, suspended sediment, pharmaceuticals and personal care products. Non-point source runoff, hydrologic alterations, and numerous waste-water discharge points resulted in the routine detection of complex mixtures of anthropogenic compounds in samples from basin stream sites. Temporal and spatial variations in concentrations and loads of nutrients, pharmaceuticals, and organic wastewater compounds were observed, primarily related to a site's proximity to point-source discharges and stream-flow dynamics. ?? 2009 ASCE.

Optimal city size and population density for the 21st century.

Science.gov (United States)

Speare A; White, M J

1990-10-01

The thesis that large scale urban areas result in greater efficiency, reduced costs, and a better quality of life is reexamined. The environmental and social costs are measured for different scales of settlement. The desirability and perceived problems of a particular place are examined in relation to size of place. The consequences of population decline are considered. New York city is described as providing both opportunities in employment, shopping, and cultural activities as well as a high cost of living, crime, and pollution. The historical development of large cities in the US is described. Immigration has contributed to a greater concentration of population than would have otherwise have occurred. The spatial proximity of goods and services argument (agglomeration economies) has changed with advancements in technology such as roads, trucking, and electronic communication. There is no optimal city size. The overall effect of agglomeration can be assessed by determining whether the markets for goods and labor are adequate to maximize well-being and balance the negative and positive aspects of urbanization. The environmental costs of cities increase with size when air quality, water quality, sewage treatment, and hazardous waste disposal is considered. Smaller scale and lower density cities have the advantages of a lower concentration of pollutants. Also, mobilization for program support is easier with homogenous population. Lower population growth in large cities would contribute to a higher quality of life, since large metropolitan areas have a concentration of immigrants, younger age distributions, and minority groups with higher than average birth rates. The negative consequences of decline can be avoided if reduction of population in large cities takes place gradually. For example, poorer quality housing can be removed for open space. Cities should, however, still attract all classes of people with opportunities equally available.

Using tradeable permits to achieve sustainability in the world's large cities. Policy design issues and efficiency conditions for controlling vehicle emissions, congestion and urban decentralization with an application to Mexico City

International Nuclear Information System (INIS)

Goddard, H.C.

1997-01-01

Many large cities in the world have serious ground level ozone problems, largely the product of vehicular emissions and thus the argued unsustainability of current urban growth patterns is frequently blamed on unrestricted private vehicle use. This article reviews Mexico City's experience with vehicle use restrictions as an emissions control program and develops the conditions for optimal quantitative restrictions on vehicle use and for complementary abatement technologies. The stochastic nature of air pollution outcomes is modelled explicitly in both the static and dynamic formulations of the control problem, in which for the first time in the literature the use of tradeable vehicle use permits is proposed as a cost-effective complement to technological abatement for mobile emissions control. This control regime gives the authorities a broader and more flexible set of instruments with which to deal more effectively with vehicle emissions, and with seasonal and stochastic variation of air quality outcomes. The market in tradeable vehicle use permits would be very competitive with low transactions costs. This control policy would have very favorable impacts on air quality, vehicle congestion and on urban form and development. Given the general political resistance to environmental taxes, this program could constitute a workable and politically palatable set of policies for controlling greenhouse gas emissions from the transport sector. 7 figs., 1 appendix, 23 refs

The UKS spacecraft operated from August 1984 through to January 1985. During that time, it made multiple crossings of the magnetopause in local time sectors extending from mid-afternoon to just behind the dawn meridian. We have surveyed the magnetometer records from these magnetopause encounters and have compiled a catalogue of flux transfer events. Using the catalogue, we find the FTE occurrence determined from the UKS data set is substantially less than that detected using data from the early ISEE 1/2 spacecraft orbits. The UKS data set shows a correlation between FTE occurrence and southward external magnetic field, but there are several instances of passes in which no FTEs are detected but for which the external field was unambiguously southward. The passes with the largest number of events are those for which the field outside the magnetopause has a large Bsub(M) component. We conclude that the lower latitude of the UKS encounters is responsible for the discrepancy with the ISEE occurrence. The most likely source region appears to be near the subsolar region. (author)

Public Transit Equity Analysis at Metropolitan and Local Scales: A Focus on Nine Large Cities in the US.

Science.gov (United States)

Griffin, Greg Phillip; Sener, Ipek Nese

2016-01-01

Recent studies on transit service through an equity lens have captured broad trends from the literature and national-level data or analyzed disaggregate data at the local level. This study integrates these methods by employing a geostatistical analysis of new transit access and income data compilations from the Environmental Protection Agency. By using a national data set, this study demonstrates a method for income-based transit equity analysis and provides results spanning nine large auto-oriented cities in the US. Results demonstrate variability among cities' transit services to low-income populations, with differing results when viewed at the regional and local levels. Regional-level analysis of transit service hides significant variation through spatial averaging, whereas the new data employed in this study demonstrates a block-group scale equity analysis that can be used on a national-scale data set. The methods used can be adapted for evaluation of transit and other modes' transportation service in areas to evaluate equity at the regional level and at the neighborhood scale while controlling for spatial autocorrelation. Transit service equity planning can be enhanced by employing local Moran's I to improve local analysis.

Following the impacts of the Eyjafjallajokull eruption in 2010, two types of volcanic eruption have been added to the UK Government's National Risk Register for Civil Emergencies. One of these, a large gas-rich volcanic eruption, was identified as a high impact natural hazard, one of the three highest priority natural hazards faced by the UK. This eruption scenario is typified by the Laki eruption in Iceland in 1783-1784. The Civil Contingency Secretariat (CCS) of the UK's Cabinet Office, responsible for Civil Protection in the UK, has since been working on quantifying the risk and better understanding its potential impacts. This involves cross-cutting work across UK Government departments and the wider scientific community in order to identify the capabilities needed to respond to an effusive eruption, to exercise the response and develop increased resilience where possible. As part of its current work, CCS has been working closely with the UK Met Office and other UK agencies and academics (represented by the co-authors and others) to generate and assess the impacts of a 'reasonable worst case scenario', which can be used for decision making and preparation in advance of an eruption. Information from the literature and the findings of an expert elicitation have been synthesised to determine appropriate eruption source term parameters and associated uncertainties. This scenario is then being used to create a limited ensemble of model simulations of the dispersion and chemical conversion of the emissions of volcanic gases during such an eruption. The UK Met Office's NAME Lagrangian dispersion model and the Centre for Ecology and Hydrology's EMEP4UK Eulerian model are both being used. Modelling outputs will address the likelihood of near-surface concentrations of sulphur and halogen species being above specified health thresholds. Concentrations at aviation relevant altitudes will also be evaluated, as well as the effects of acid deposition of volcanic species on

Monitoring sensible heat flux over urban areas in a high-altitude city using Large Aperture Scintillometer and Eddy Covariance

Urbanization leads to modifications of surface energy balance which governs the momentum, heat and mass transfer between urban canopy layer and the atmosphere, thus impacts dynamic processes in the urban ABL and ultimately influence the local, regional and even global climate. It is essential to obtain accurate urban ABL observations to enhance our understanding of land-atmosphere interaction process over the urban area and help to improve the prediction ability of numerical model. However, up to now, there are rarely observations in high latitude cities. In one of the highest cities in the world, Lhasa, Eddy Covariance (EC) measurements have been ongoing since 10 August 2016 and a Large Aperture Scintillometer (LAS) started to work on 12 November 2016, in addition to a UHI network which has been running since 2012. Taking advantage of these observations, this poster will estimate and analyze the surface energy balance in the winter of 2016 in Lhasa, with an emphasis on sensible heat flux. An analytical footprint model and the radiative surface temperature retrieved from Landsat 8 will be employed to compare EC and LAS measurements.

Conference Scene: Induced pluripotent cells: a new path for regenerative medicine. 7 October 2010, BioPark, Welwyn Garden City, Hertfordshire, UK.

Science.gov (United States)

Crutzen, Hélène S G

2011-01-01

Embryonic stem cells and induced pluripotent stem (iPS) cells, which are embryonic stem-like cells derived from adult tissues, have the broadest differentiation potential. These cells are unique in their ability to self-renew, to be maintained in an undifferentiated state for long periods of culturing and to give rise to many different cell lineages including germ-line cells. They therefore represent an invaluable tool for facilitating research towards the realization of regenerative medicine. The recent developments in embryonic stem cell and iPS cell technology have allowed human cell models to be developed that will hopefully provide novel platforms for disease analysis not only at the basic science level, but also for drug discovery and screening, and other clinical applications. This 1-day conference, chaired by Professor Peter Andrews from the University of Sheffield, UK, and Dr Chris Denning from the University of Nottingham, UK, focused on generation of iPS cells, their differentiation into specific fates and applications to disease modeling. It consisted of 11 talks by UK-based and international researchers, and three posters; Ms Azra Fatima from Cologne University, Germany, won the competition for her poster on the derivation of iPS cells from a patient with arrhythmogenic right ventricular cardiomyopathy.

Changes needed to medicine in the UK before senior UK-trained doctors, working outside the UK, will return: questionnaire surveys undertaken between 2004 and 2015.

To report the changes to UK medicine which doctors who have emigrated tell us would increase their likelihood of returning to a career in UK medicine. Questionnaire survey. UK-trained medical graduates. Questionnaires were sent 11 years after graduation to 7158 doctors who qualified in 1993 and 1996 in the UK: 4763 questionnaires were returned. Questionnaires were sent 17 and 19 years after graduation to the same cohorts: 4554 questionnaires were returned. Comments from doctors working abroad about changes needed to UK medicine before they would return. Eleven years after graduation, 290 (6%) of respondents were working in medicine abroad; 277 (6%) were doing so 17/19 years after graduation. Eleven years after graduation, 53% of doctors working abroad indicated that they did not intend to return, and 71% did so 17/19 years after graduation. These respondents reported a number of changes which would need to be made to UK medicine in order to increase the likelihood of them returning. The most frequently mentioned changes cited concerned 'politics/management/funding', 'pay/pension', 'posts/security/opportunities', 'working conditions/hours', and 'factors outside medicine'. Policy attention to factors including funding, pay, management and particularly the clinical-political interface, working hours, and work-life balance may pay dividends for all, both in terms of persuading some established doctors to return and, perhaps more importantly, encouraging other, younger doctors to believe that the UK and the National Health Service can offer them a satisfying and rewarding career.

Objective Dietary changes which improve health are also likely to be beneficial for the environment by reducing emissions of greenhouse gases (GHG). However, previous analyses have not accounted for the potential acceptability of low GHG diets to the general public. This study attempted to quantify the health effects associated with adopting low GHG emission diets in the UK. Design Epidemiological modelling study. Setting UK. Participants UK population. Intervention Adoption of diets optimised to achieve the WHO nutritional recommendations and reduce GHG emissions while remaining as close as possible to existing dietary patterns. Main outcome Changes in years of life lost due to coronary heart disease, stroke, several cancers and type II diabetes, quantified using life tables. Results If the average UK dietary intake were optimised to comply with the WHO recommendations, we estimate an incidental reduction of 17% in GHG emissions. Such a dietary pattern would be broadly similar to the current UK average. Our model suggests that it would save almost 7 million years of life lost prematurely in the UK over the next 30 years and increase average life expectancy by over 8 months. Diets that result in additional GHG emission reductions could achieve further net health benefits. For emission reductions greater than 40%, improvements in some health outcomes may decrease and acceptability will diminish. Conclusions There are large potential benefits to health from adopting diets with lower associated GHG emissions in the UK. Most of these benefits can be achieved without drastic changes to existing dietary patterns. However, to reduce emissions by more than 40%, major dietary changes that limit both acceptability and the benefits to health are required. PMID:25929258

The UK has witnessed a considerable increase in immigration in the past decade. Migrant may face barriers to accessing appropriate health care on arrival and the current focus on screening certain migrants for tuberculosis on arrival is considered inadequate. We assessed the implications for an inner-city London Infectious Diseases Department in a high migrant area. We administered an anonymous 20-point questionnaire survey to all admitted patients during a 6 week period. Questions related to sociodemographic characteristics and clinical presentation. Analysis was by migration status (UK born vs overseas born). 111 of 133 patients completed the survey (response rate 83.4%). 58 (52.2%) were born in the UK; 53 (47.7%) of the cohort were overseas born. Overseas-born were over-represented in comparison to Census data for this survey site (47.7% vs 33.6%; proportional difference 0.142 [95% CI 0.049-0.235]; p = 0.002): overseas born reported 33 different countries of birth, most (73.6%) of whom arrived in the UK pre-1975 and self-reported their nationality as British. A smaller number (26.4%) were new migrants to the UK (arrival and once settled through primary care services. A more organised and holistic approach to migrant health care is required.

Air pollution impacts of speed limitation measures in large cities: The need for improving traffic data in a metropolitan area

Science.gov (United States)

Baldasano, José M.; Gonçalves, María; Soret, Albert; Jiménez-Guerrero, Pedro

2010-08-01

Assessing the effects of air quality management strategies in urban areas is a major concern worldwide because of the large impacts on health caused by the exposure to air pollution. In this sense, this work analyses the changes in urban air quality due to the introduction of a maximum speed limit to 80 km h -1 on motorways in a large city by using a novel methodology combining traffic assimilation data and modelling systems implemented in a supercomputing facility. Albeit the methodology has been non-specifically developed and can be extrapolated to any large city or megacity, the case study of Barcelona is presented here. Hourly simulations take into account the entire year 2008 (when the 80 km h -1 limit has been introduced) vs. the traffic conditions for the year 2007. The data has been assimilated in an emission model, which considers hourly variable speeds and hourly traffic intensity in the affected area, taken from long-term measurement campaigns for the aforementioned years; it also permits to take into account the traffic congestion effect. Overall, the emissions are reduced up to 4%; however the local effects of this reduction achieve an important impact for the adjacent area to the roadways, reaching 11%. In this sense, the speed limitation effects assessed represent enhancements in air quality levels (5-7%) of primary pollutants over the area, directly improving the welfare of 1.35 million inhabitants (over 41% of the population of the Metropolitan Area) and affecting 3.29 million dwellers who are potentially benefited from this strategy for air quality management (reducing 0.6% the mortality rates in the area).

1995-01-01

A detailed critique is offered of United Kingdom (UK) political policy with respect to the Non-Proliferation Treaty, an interim agreement valid while nuclear disarmament was supposed to occur, by a representative of Greenpeace, the anti-nuclear campaigning group. The author argues that the civil and military nuclear programmes are still firmly linked, and emphasises his opinions by quoting examples of how UK politicians have broken treaty obligations in order to pursue their own political, and in some cases financial, goals. It is argued that the treaty has failed to force nuclear countries to disarm because of its promoted civil nuclear power programmes. (U.K.)

The City Blueprint Approach: Urban Water Management and Governance in Cities in the U.S.

Feingold, Daniel; Koop, Stef; van Leeuwen, Kees

2018-01-01

In this paper, we assess the challenges of water, waste and climate change in six cities across the U.S.: New York City, Boston, Milwaukee, Phoenix, Portland and Los Angeles. We apply the City Blueprint ® Approach which consists of three indicator assessments: (1) the Trends and Pressures Framework (TPF), (2) the City Blueprint Framework (CBF) and (3) the water Governance Capacity Framework (GCF). The TPF summarizes the main social, environmental and financial pressures that may impede water management. The CBF provides an integrated overview of the management performances within the urban watercycle. Finally, the GCF provides a framework to identify key barriers and opportunities to develop governance capacity. The GCF has only been applied in NYC. Results show that all cities face pressures from heat risk. The management performances regarding resource efficiency and resource recovery from wastewater and solid waste show considerable room for improvement. Moreover, stormwater separation, infrastructure maintenance and green space require improvement in order to achieve a resilient urban watercycle. Finally, in New York City, the GCF results show that learning through smart monitoring, evaluation and cross-stakeholder learning is a limiting condition that needs to be addressed. We conclude that the City Blueprint Approach has large potential to assist cities in their strategic planning and exchange of knowledge, experiences and lessons. Because the methodology is well-structured, easy to understand, and concise, it may bridge the gap between science, policy and practice. It could therefore enable other cities to address their challenges of water, waste and climate change.

Past cross-national comparisons of socioeconomic segregation have been undercut by lack of comparability in measures, data, and concepts. Using IRIS data from the French Census of 2008 and the French Ministry of Finance as well as tract data from the American Community Survey (2006-2010) and the U.S. Department of Housing and Urban Development Picture of Subsidized Households, and constructing measures to be as similar as possible, we compare socioeconomic segregation in metropolitan areas with a population of more than 1 million in France and the United States. We find much higher socioeconomic segregation in large metropolitan areas in the United States than in France. We also find (1) a strong pattern of low-income neighborhoods in central cities and high-income neighborhoods in suburbs in the United States, but varying patterns across metropolitan areas in France; (2) that high-income persons are the most segregated group in both countries; (3) that the shares of neighborhood income differences that can be explained by neighborhood racial/ethnic composition are similar in France and the United States; and (4) that government-assisted housing is disproportionately located in the poorest neighborhoods in the United States but is spread across many neighborhood income levels in France. We conclude that differences in government provision of housing assistance and levels of income inequality are likely important contributing factors to the Franco-U.S. difference in socioeconomic segregation.

Economic instruments for the control of acid rain in the UK

Pototschnig, A.

1994-01-01

UK environmental policy has traditionally focused on administrative controls. The paper considers the introduction of market-based instruments in the context of the control of SO 2 emissions from large combustion plants. These are responsible for more than 80% of total emissions in the UK. The analysis focuses on England and Wales, and considers three separate sectors: the electricity supply industry (ESI), refineries and other industry. It looks at the options for achieving the emission quotas for large combustion plants set by the Large Combustion Plant Directive. Electricity generators are already allowed some discretion, subject to agreement by the enforcing authorities, to allocate pollution control responsibilities among power stations within each company. Given the similarity in the power station mix between National Power and PowerGen, the advantages of extending the mechanism to include power stations of both companies would be limited. More substantial savings can be obtained when refineries and other large industrial plants, which have much higher abatement costs, are included in the scheme. An emission permit scheme which includes the ESI, refineries and other industry is therefore proposed, and is preferred to a mechanism based on emission charges. Some features of this scheme are then discussed. 16 refs., 3 figs., 5 tabs

Full Text Available The British Geological Survey is responsible for conducting the UK geomagnetic repeat station programme. Measurements made at the UK repeat station sites are used in conjunction with the three UK magnetic observatories: Hartland, Eskdalemuir and Lerwick, to produce a regional model of the local field each year. The UK network of repeat stations comprises 41 stations which are occupied at approximately 3-4 year intervals. Practices for conducting repeat station measurements continue to evolve as advances are made in survey instrumentation and as the usage of the data continues to change. Here, a summary of the 2009 and 2010 UK repeat station surveys is presented, highlighting the measurement process and techniques, density of network, reduction process and recent results.

The Practicalities of Crowdsourcing: Lessons from the Tea Bag Index - UK

Duddigan, Sarah; Alexander, Paul; Shaw, Liz; Collins, Chris

2017-04-01

The Tea Bag Index -UK is a collaborative project between the University of Reading and the Royal Horticultural Society (RHS), working with members of the gardening community as citizen scientists. This project aims to quantify how decomposition varies across the country, and whether decomposition is influenced by how gardeners manage their soil, particularly with respect to the application of compost. Launched in 2015 as part of a PhD project, the Tea Bag Index- UK project asks willing volunteers to bury tea bags in their gardens, as part of a large scale, litter bag style decomposition rate study. Over 450 sets of tea bags have been dispatched to participants, across the length and breadth of the UK. The group was largely recruited via social media, magazine articles and public engagement events and active discourse was undertaken with these citizen scientists using Facebook, Twitter and regular email communication. In order to run a successful crowdsourcing citizen science project there are number of stages that need to be considered including (but not limited to): planning; launch and recruitment; communications; and feedback. Throughout a project of this nature an understanding of the motivations of your volunteers is vital. Reflecting on these motivations while publicising the project, and communicating regularly with its participants is incredibly important for a successful project.

Education, Occupation and Career Expectations: Determinants of the Gender Pay Gap for UK Graduates

2006-01-01

Despite anti-discrimination policies, women are paid 20% less then men in the UK. A large proportion of this wage gap is usually left unexplained. In this paper, I investigate whether the unexplained component is due to misspecification. Using a sample of recent UK graduates, I examine the role of choice variables (subject of study and occupation) as well as career expectations and aspirations. The evidence indicates that women are more altruistic and less career-oriented than men. Career bre...

Towards an urban planners’ perspective on Smart City

Directory of Open Access Journals (Sweden)

Rocco Papa

2013-04-01

Full Text Available The concept of “Smart City”, providing a solution for making cities more efficient and sustainable, has been quite popular in recent years, encouraging reflections, ideas, researches and projects for a “smart” urban development. A smart city is generally meant as a city capable of joining “competitiveness” and “sustainability”, by integrating different dimensions of development and addressing infrastructural investments able to support economic growth as well as the quality of life of communities, a more careful management of natural resources, a greater transparency and participation to decision-making processes. Based on those assumptions, this contribution tackle the controversial subject of Smart City, starting from the review of the scientific Italian and international literature that, from the Eighties to the Nineties, has been largely focused on ICTs and their impacts on urban development. Then, the focus shifts on the large debate on smart cities that has been developing from the beginning of 2000s and on the numerous institutional initiatives up to now implemented by the European Union for building up the Smart City. Finally, the article highlights how, despite these efforts, a shared definition of the term is still missing and current approaches to the issue are still very heterogeneous; it emphasizes, on the opposite, the key-role that urban planning, grounding on a holistic approach to cities’ development, should play in coordinating and integrating urban policies addressed to building up a Smart City.

Using photovoice methods to explore older people's perceptions of respect and social inclusion in cities: Opportunities, challenges and solutions

Full Text Available Urbanisation and population ageing have contributed to recognise cities as important settings for healthy ageing. This paper considers opportunities, challenges and solutions of using photovoice methods for exploring how individuals perceive their cities and the contribution this makes to their health. It focuses on one aspect of older people's experiences – respect and social inclusion, in the context of a community-based participatory research. Drawing on selected findings (participants' photographs, associated quotes and researchers' field notes, we provide an assessment of the suitability of photovoice methodology for the intended purpose. Four groups of older people (n=26; aged 60 years or more from four contrasting geographical areas in Liverpool, UK, were recruited purposively. Participants photographed perceived positive and negative aspects of respect and social inclusion in the city, reflecting on the meanings of the photographs in individual (n=23 and group interviews (n=9. Thematic and content analysis was conducted using NVivo 10 software.The work reported here provides insights into how participants engage with the photovoice process; factors preventing taking photos of interest; and how photographs complement interviews and focus groups. The findings demonstrate that photovoice both facilitated the dissemination of personalised relevant knowledge, and encouraged critical dialogue between participants, and city stakeholders. Reported difficulties included photography of negative and social concepts, and anxiety when taking photographs due to (i expectations of what is a ‘proper’ photograph, and (ii the need to obtain consent from subjects. With preparation, training, and discussion of participants’ ideas not expressed through photographs, photovoice was well-suited to this topic, providing insights complementing other research methods. Through analysing the application of photovoice for exploring perceptions of respect and

Toward a healthier city: nutrition standards for New York City government.

Poor diet is a leading cause of disability, death, and rising health care costs. Government agencies can have a large impact on population nutrition by adopting healthy food purchasing policies. In 2007, New York City (NYC) began developing a nutrition policy for all foods purchased, served, or contracted for by City agencies. A Food Procurement Workgroup was created with representatives from all City agencies that engaged in food purchasing or service, and the NYC Health Department served as technical advisor. The NYC Standards for Meals/Snacks Purchased and Served (Standards) became a citywide policy in 2008. The first of its kind, the Standards apply to more than 3,000 programs run by 12 City agencies. This paper describes the development process and initial implementation of the Standards. With more than 260 million meals and snacks per year covered, the Standards increase demand for healthier products, model healthy eating, and may also affect clients' food choices beyond the institutional environment. Our experience suggests that implementation of nutrition standards across a wide range of diverse agencies is feasible, especially when high-level support is established and technical assistance is available. Healthy procurement policies can ensure that food purchased by a jurisdiction supports its public health efforts. Published by Elsevier Inc.

This paper gives an overview of the set up, methodology and the obtained results of the CityDelta (phase 1 and 2) project. In the context of the Clean Air For Europe programme of the European Commission, the CityDelta project was designed to evaluate the impact of emission-reduction strategies on air quality at the European continental scale and in European cities. Ozone and particulate matter (PM) are the main components that have been studied. To achieve this goal, a model intercomparison study was organized with the participation of more than 20 modelling groups with a large number of modelling configurations. Two following main topics can be identified in the project. First, in order to evaluate their strengths and weaknesses, the participating models were evaluated against observations in a control year (1999). An accompanying paper will discuss in detail this evaluation aspect for four European cities. The second topic is the actual evaluation of the impact of emission reductions on levels of ozone and PM, with particular attention to the differences between large-scale and fine-scale models. An accompanying paper will discuss this point in detail. In this overview paper the main input to the intercomparison is described as well as the use of the ensemble approach. Finally, attention is given to the policy relevant issue on how to implement the urban air quality signal into large-scale air quality models through the use of functional relationships. (authors)

We find a noticeable degree of heterogeneity across the sample companies. Our panel results show that, after controll...

Wind energy - current status in the UK

International Nuclear Information System (INIS)

Lindley, D.

1995-01-01

Twenty two windfarms are operational or are under construction in the U.K. They have a total installed capacity of approximately 140 MW and will generate about 360 GWh in a full year and provide the electricity needs of about 250 000 individuals and save the emission of about 400 000 tonnes of CO 2 each year. Developments so far have required an investment of about Pound 140 million provided mostly by banks and large corporate investors. Financing these projects has broken new ground for renewable technologies and established a framework for the financing of windfarms built using future NFFO contracts. Obtaining planning consents for these windfarms has involved thirteen public inquiries, eight of which have been successful. Four of these remain unused and the result of another is awaited. Statutory and other bodies have responded to the rapid deployment of windfarms by issuing guidelines and these together with Public Inquiry documentation now provide invaluable guidance for the industry. The U.K. market is arguably the most 'open' in Europe and Danish Wind Turbine manufacturers have gained over 50 per cent of the total market. A Japanese manufacturer has gained 25 per cent whilst the major U.K. turbine supplier has gained 17 per cent market share. There are still over thirty manufacturers worldwide and signs that a combination of innovation and market pressures are continuing to reduce the costs of wind energy. (author)

In order to enhance Chinese workers' occupational safety awareness, it is essential to learn from developed countries' experiences. This article investigates thoroughly occupational safety and health (OSH) in China and the UK; moreover, the article performs a comparison of Chinese and British OSH training-related laws, regulations and education system. The following conclusions are drawn: China's work safety continues to improve, but there is still a large gap compared with the UK. In China a relatively complete vocational education and training (VET) system has been established. However, there exist some defects in OSH. In the UK, the employer will not only pay attention to employees' physiological health, but also to their mental health. The UK's VET is characterized by classification and grading management, which helps integrate OSH into the whole education system. China can learn from the UK in the development of policies, VET and OSH training.

Carbon dioxide (CO2) and methane (CH4) mole fractions were measured at four near-ground sites located in and around London during the summer of 2012 with a view to investigating the potential of assimilating such measurements in an atmospheric inversion system for the monitoring of the CO2 and CH4 emissions in the London area. These data were analysed and compared with simulations using a modelling framework suited to building an inversion system: a 2 km horizontal resolution south of England configuration of the transport model CHIMERE driven by European Centre for Medium-Range Weather Forecasts (ECMWF) meteorological forcing, coupled to a 1 km horizontal resolution emission inventory (the UK National Atmospheric Emission Inventory). First comparisons reveal that local sources, which cannot be represented in the model at a 2 km resolution, have a large impact on measurements. We evaluate methods to filter out the impact of some of the other critical sources of discrepancies between the measurements and the model simulation except that of the errors in the emission inventory, which we attempt to isolate. Such a separation of the impact of errors in the emission inventory should make it easier to identify the corrections that should be applied to the inventory. Analysis is supported by observations from meteorological sites around the city and a 3-week period of atmospheric mixing layer height estimations from lidar measurements. The difficulties of modelling the mixing layer depth and thus CO2 and CH4 concentrations during the night, morning and late afternoon lead to focusing on the afternoon period for all further analyses. The discrepancies between observations and model simulations are high for both CO2 and CH4 (i.e. their root mean square (RMS) is between 8 and 12 parts per million (ppm) for CO2 and between 30 and 55 parts per billion (ppb) for CH4 at a given site). By analysing the gradients between the urban sites and a suburban or rural reference site, we

The Ubiquitous-Eco-City of Songdo: An Urban Systems Perspective on South Korea's Green City Approach

Directory of Open Access Journals (Sweden)

Paul D. Mullins

2017-06-01

Full Text Available Since the 1980s, within the broader context of studies on smart cities, there has been a growing body of academic research on networked cities and “computable cities” by authors including Manuel Castells (Castells, 1989; Castells & Cardoso, 2005, William Mitchell (1995, Michael Batty (2005, 2013, and Rob Kitchin (2011. Over the last decade, governments in Asia have displayed an appetite and commitment to construct large scale city developments from scratch—one of the most infamous being the smart entrepreneurial city of Songdo, South Korea. Using Songdo as a case study, this paper will examine, from an urban systems perspective, some of the challenges of using a green-city model led by networked technology. More specifically, this study intends to add to the growing body of smart city literature by using an external global event—the global financial crisis in 2008—to reveal what is missing from the smart city narrative in Songdo. The paper will use the definition of an urban system and internal subsystems by Bertuglia et al. (1987 and Bertuglia, Clarke and Wilson (1994 to reveal the sensitivity and resilience of a predetermined smart city narrative. For instance, what happens if the vision moves from the originally intended international-orientated population towards remarketing the city to attract a domestic middle-class population. The lens of the financial crisis in 2008 revealed that the inherent inflexibility of a closed-system approach in Songdo was not sufficiently resilient to external shocks. The shift towards a domestic middle-class population revealed the inequality in accessing the city services in a system designed with formalized and rigid inputs and outputs. By focusing predominantly on technology, the social dimensions of the city were not part of Songdo’s smart city vocabulary. Therefore, in adopting a technologically deterministic approach (Mullins & Shwayri, 2016 to achieving efficiency and combating environmental

Improved flexibility with large-scale variable renewable power in cities through optimal demand side management and power-to-heat conversion

Highlights: • New models for optimal control of shiftable loads and power-to-heat conversion. • Full technical and economic potential with optimal controls. • Detailed time series of shiftable loads based on empirical data. • Case study of Helsinki (Finland) with over 90% share of district heating. • Positive net present values in cost-optimal operation. - Abstract: Solar and wind power are potential carbon-free energy solutions for urban areas, but they are also subject to large variability. At the same time, urban areas offer promising flexibility solutions for balancing variable renewable power. This paper presents models for optimal control of power-to-heat conversion to heating systems and shiftable loads in cities to incorporate large variable renewable power schemes. The power-to-heat systems comprise heat pumps, electric boilers, and thermal storage. The control strategies comprise optimal matching of load and production, and cost-optimal market participation with investment analysis. All analyses are based on hourly data. The models are applied to a case study in Helsinki, Finland. For a scheme providing ca. 50% of all electricity in the city through self-consumption of variable renewables, power-to-heat with thermal storage could absorb all the surplus production. A significant reduction in the net load magnitude was obtained with shiftable loads. Investments to both power-to-heat and load shifting with electric heating and commercial refrigeration have a positive net present value if the resources are controlled cost-optimally.

Expansion and growth in Chinese cities, 1978–2010

Schneider, A; Mertes, C M

2014-01-01

It has long been recognized that compact versus more sprawling urban forms can have very different environmental impacts. As the Chinese population continues to rapidly urbanize, the size, shape, and configuration of cities in China will undoubtedly change to accommodate expansion of housing, industry, and commerce, causing direct and indirect environmental impacts at multiple scales. It is therefore imperative to understand how urban areas are evolving as socio-economic reforms in China are implemented across different regions. This paper compares trends in 142 Chinese cities (including 17 agglomerations) to understand urban expansion and population growth following reforms, 1978–2010. The results show that cities tripled in size, while doubling in population over the same period. In coastal areas targeted by early policies, urban land increased 4–5 times since 1978, for all city sizes. Large agglomerations are the primary consumers of land in coastal and western regions, each adding an average of 450 km 2 during the study period, while small-medium cities consumed an average 20 km 2 . Although populations in these agglomerations increased an average 1.3 million, 2000–2010, cities within 100 km of each agglomeration grew >1.8 million collectively. Proximity to large agglomerations contributed to the growth of small-medium cities, especially in western regions. (paper)

Strategic marketing in the UK tobacco industry.

Anderson, Susan; Hastings, Gerard; MacFadyen, Lynn

2002-08-01

Tobacco-industry marketing has played a central part in the global spread of tobacco use and addiction. Although the absolute size of the tobacco market has dwindled, the industry is still immensely successful, largely due to sophisticated and manipulative marketing strategies. The UK tobacco industry identifies target groups and builds enduring relationships based on careful brand management. Potential customers are exposed to brands which are likely to appeal to them most. Tobacco companies tailor their products to target markets by altering the content of tar and nicotine, and by adding flavourings to produce a distinctive taste. Marketing strategies ensure that the products are promoted heavily at the point of sale, and directed advertising and sponsorship agreements are used to increase the visibility of the brand and strengthen its image. Tobacco companies also target non-consumer organisations such as retailers and policy makers with the aim of creating the best possible business environment for tobacco sales. We review published evidence, internal-advertising-agency documents, and observational data about tobacco promotion, and discuss the use of targeted marketing strategies in the UK.

Sustainability for Shrinking Cities | Science Inventory | US EPA

Science.gov (United States)

Shrinking cities are widespread throughout the world despite the rapidly increasing global urban population. These cities are attempting to transition to sustainable trajectories to improve the health and well-being of urban residents, to build their capacity to adapt to changing conditions and to cope with major events. The dynamics of shrinking cities are different than the dynamics of growing cities, and therefore intentional research and planning around creating sustainable cities is needed for shrinking cities. We propose research that can be applied to shrinking cities by identifying parallel challenges in growing cities and translating urban research and planning that is specific to each city’s dynamics. In addition, we offer applications of panarchy concepts to this problem. The contributions to this Special Issue take on this forward-looking planning task through drawing lessons for urban sustainability from shrinking cities, or translating general lessons from urban research to the context of shrinking cities. Humans are rapidly becoming an urban species, with greater populations in urban areas, increasing size of these urban areas, and increasing number of very large urban areas. As a consequence, much of what we know about cities is focused on how they grow and take shape, the strains that their growth puts on city infrastructure, the consequences for human and nonhuman inhabitants of these cities and their surroundings, and the policies which can

This paper presents an illustrative visualization technique that provides expressive representations of large-scale 3D city models, inspired by the tradition of artistic and cartographic visualizations typically found in bird"s-eye view and panoramic maps. We define a collection of city model components and a real-time multi-pass rendering algorithm that achieves comprehensible, abstract 3D city model depictions based on edge enhancement, color-based and shadow-based depth cues, and procedural facade texturing. Illustrative visualization provides an effective visual interface to urban spatial information and associated thematic information complementing visual interfaces based on the Virtual Reality paradigm, offering a huge potential for graphics design. Primary application areas include city and landscape planning, cartoon worlds in computer games, and tourist information systems.

Travel for medical treatment is an aspect of globalization and health that is comparatively less understood. Little is known about volume, characteristic and motivation of medical tourists, limiting understanding of effects on health systems and patients. Thailand is amongst a handful of countries that have positioned themselves as medical tourism destination. This paper examines in unprecedented detail volume and characteristics of medical tourists who travel from the UK to Thailand for treatment. As part of a wider medical tourism study, authors gained access to over 4000 patient records from the five largest private hospitals in Thailand. These included information on country of origin, gender, age, arrival month, hospitalization, diagnosis, procedures, length of stay, medical expenditure and type of payment. Patient records were analysed to understand who travels and findings were triangulated with data from the UK International Passenger Survey (IPS). 104,830 medical tourists visited these hospitals in Thailand in 2010. While patients originate all over the world, UK medical tourists represent the largest group amongst Europeans. The majority UK medical tourists (60%) have comparatively small, elective procedures, costing less than USD 500. A significant minority of patients travel for more serious orthopedic and cardiothoracic procedures. Data of individual patient records from Thailand shows a higher number of UK patients traveled to Thailand than indicated by the IPS. Thailand is attracting a large number of medical tourists including larger numbers of UK patients than previously estimated. However, as many patients travel for comparatively minor procedures treatment may not be their primary motivation for travel. The small but significant proportion of older UK residents traveling for complex procedures may point to challenges within the NHS.

The traffic situation in Chinese urban areas is continuing to deteriorate. To make a better planning and designing of the public transport system, it is necessary to make profound research on the structure of urban public transport networks (PTNs). We investigate 97 large- and medium-sized cities’ PTNs in China, construct three types of network models — bus stop network, bus transit network and bus line network, then analyze the structural characteristics of them. It is revealed that bus stop network is small-world and scale-free, bus transit network and bus line network are both small-world. Betweenness centrality of each city’s PTN shows similar distribution pattern, although these networks’ size is various. When classifying cities according to the characteristics of PTNs or economic development level, the results are similar. It means that the development of cities’ economy and transport network has a strong correlation, PTN expands in a certain model with the development of economy.

The rapid and important development of large urban areas ('mega-cities'), especially in developing countries, causes and will cause serious air-quality problems. Pollutant measurements in these cities help to characterize the chemical nature and the quantity of these pollutants and to constrain air-quality models. This paper focuses on measurements of volatile organic compounds and aerosols that have an important impact on air quality. We present a brief review on existing measurements and experimental strategies in mega-cities and then we show results from recent measurement campaigns that took place in two contrasted mega-cities: Paris and Beijing.

Ho Chi Minh City is a large city that will become a mega-city in the near future. The city struggles with a rapidly increasing flow of municipal solid waste and a foreseeable scarcity of land to continue landfilling, the main treatment of municipal solid waste up to now. Therefore, additional municipal solid waste treatment technologies are needed. The objective of this article is to support decision-making towards more sustainable and cost-effective municipal solid waste strategies in developing countries, in particular Vietnam. A quantitative decision support model is developed to optimise the distribution of municipal solid waste from population areas to treatment plants, the treatment technologies and their capacities for the near future given available infrastructure and cost factors. © The Author(s) 2015.

Structure and staffing of radiotherapy physics in the UK

International Nuclear Information System (INIS)

Thwaites, D I

1995-01-01

In 1989 IPSM brought out a policy document on the role of the physical scientist in radiotherapy. At roughly the same time IPSM also produced recommended minimum staffing levels for the medical physics support of radiotherapy, which drew heavily on comprehensive reviews of both physicist and physics technician staffing carried out by the Scottish Radiotherapy Physicists Group in 1980 (updated in 1989). The IPSM figures remain professional recommendations and have not been taken up by any official body. However some of the Scottish figures were included in a SHHD Planning Council Scientific Advisory report and so have some measure of official endorsement. All these figures were derived specifically for the UK situation of essentially regional oncology centres, where generally medium to large radiotherapy departments are the norm, to concentrate equipment, expertise and experience. Thus there are approximately 60 centres for a population of 55 million. In addition the recommendations reflect the typical structure of UK departments, in terms of professional roles and relationships. The current situation regarding physicist and physics technician numbers is reviewed, using evidence from recent surveys. The UK and other recommendations are applied to a number of representative centres and the figures obtained are compared to each other and to the actual staffing levels

The impact of deprivation on youth violence: a comparison of cities and their feeder towns.

66,000 children and adolescents are treated at emergency departments (EDs) in England and Wales each year for assault injury. The aim of this study was to compare adolescent assault injury rates in cities and towns and determine how assault injury varies with deprivation and gender. The study was set in three cities in Wales, UK, and their surrounding towns. Subjects were 11-17 year olds treated for assault injury at one of seven EDs from 1 October 2005 to 30 September 2006. Area of residence (electoral divisions, EDivs) was identified from patient postcode. EDivs were aggregated into deprivation fifths for males and females and cities and towns. Assault injury rates, rate ratios and 95% CIs were calculated. 1472 children and adolescents of 11-17 years old were treated for assault injury. Male city assault injury rates were 14.2/1000 11-17 year olds; and 13.1 in towns. Female city assault injury rates were 6.0; and 5.6 in towns. In the most deprived city areas males had assault injury rates 2.6 times (95% CI 1.85 to 3.59) that of the most affluent, compared with 2.0 times in towns (95% CI 1.39 to 2.86). For females, the most deprived city areas had assault injury rates 5.3 times that of the most affluent (95% CI 2.93 to 9.41), compared with 2.8 times in towns (95% CI 1.47 to 5.28). Injury in youth violence increased with increasing deprivation in cities and their feeder towns. This was true for boys and girls, though rates for boys were consistently higher. This link between assault injury and deprivation was stronger for girls in cities than in feeder towns. Strategies to prevent youth violence need to include improved safeguarding arrangements for girls living in the most deprived city areas.

Obesity is a major health issue and an important public health target for urban design. However, the evidence for identifying the optimum residential density in relation to obesity has been far from compelling. We examined the association of obesity with residential density in a large and diverse population sample drawn from the UK Biobank to identify healthy-weight-sustaining density environments. For this full-data, cross-sectional analysis, we used UK Biobank data for adult men and women aged 37-73 years from 22 cities across the UK. Baseline examinations were done between 2006 and 2010. Residential unit density was objectively assessed within a 1 km street catchment of a participant's residence. Other activity-influencing built environment factors were measured in terms of density of retail, public transport, and street-level movement density, which were modelled from network analyses of through movement of street links within the defined catchment. We regressed adiposity indicators of body-mass index (BMI; kg/m 2 ), waist circumference (cm), whole body fat (kg), and obesity (WHO criteria of BMI ≥30 kg/m 2 ) on residential density (units per km 2 ), adjusting for activity-influencing built environment factors and individual covariates. We also investigated effect modification by age, sex, employment status, and physical activity. We used a series of linear continuous and logistic regression models and non-linear restricted cubic spline models as appropriate. Of 502 649 adults in the prospective cohort, 419 562 (83·5%) participants across 22 UK Biobank assessment centres met baseline data requirements and were included in the analytic sample. The fitted restricted cubic spline adiposity-residential density dose-response curve identified a turning point at a residential density of 1800 residential units per km 2 . Below a residential density of 1800 units per km 2 , an increment of 1000 units per km 2 was positively related with adiposity, being associated

Cities and Climate - What Visions?

International Nuclear Information System (INIS)

Haentjens, Jean

2015-01-01

Given the difficulty of achieving a global agreement to cope with the challenges of climate change or even a national resilience programme, an increasing number of initiatives are coming up from the local level for preemptively implementing policies to adapt to climate change or combat it. There are several towns and cities across the world that have taken this line (Copenhagen, Totnes, Vaexjoe, Bristol, etc.) but, as Jean Haentjens shows here, an effective response to climate change requires the development of a genuine strategic vision capable of mobilizing all the actors concerned. For the moment, the towns and cities that have managed to come up with such a vision are few and far between. After a -largely historical- review of the importance of vision in changes of urban paradigm, Jean Haentjens stresses how much twenty-first century eco-urbanism broadens the range of possible solutions to the many issues facing our towns and cities today. But, though digital innovations in fact offer new opportunities at the local level, we should nonetheless be wary of 'technological solutionism': the new technologies are tools which towns and cities can use to their advantage, but to become really 'smart' they have to develop a vision. After presenting a series of established or emerging urban models (the frugal city, the creative city, the leisure city and the eco-metropolis), along with the values and imaginative conceptions that underpin them, this article shows - without being unaware of the potential obstacles - how a town or city can produce and renew its strategic vision to reinvent itself and meet the challenges of today

Gas reactor and associated nuclear experience in the UK relevant to high temperature reactor engineering

International Nuclear Information System (INIS)

Beech, D.J.; May, R.

2000-01-01

In the UK, the NNC played a leading role in the design and build of all of the UK's commercial magnox reactors and advanced gas-cooled reactors (AGRs). It was also involved in the DRAGON project and was responsible for producing designs for large scale HTRs and other gas reactor designs employing helium and carbon dioxide coolants. This paper addresses the gas reactor experience and its relevance to the current HTR designs under development which use helium as the coolant, through the consideration of a representative sample of the issues addressed in the UK by the NNC in support of the AGR and other reactor programmes. Modern HTR designs provide unique engineering challenges. The success of the AGR design, reflected in the extended lifetimes agreed upon by the licensing authorities at many stations, indicates that these challenges can be successfully overcome. The UK experience is unique and provides substantial support to future gas reactor and high temperature engineering studies. (authors)

Cotton, R A; Giffard, A

2001-07-01

Technical and non-technical issues affecting the introduction of wood pellet-fired heating to the UK were investigated with the aim of helping to establish a wood pellet industry in the UK. The project examined the growth and status of the industry in continental Europe and North America, reviewed relevant UK standards and legislation, identified markets for pellet heating in the UK, organised workshops and seminars to demonstrate pellet burning appliances, carried out a trial pelletisation of a range of biomass fuels, helped to set up demonstration installations of pellet-fired appliances, undertook a promotional campaign for wood pellet fuel and compiled resource directories for pellet fuel and pellet burning appliances in the UK. The work was completed in three phases - review, identification and commercialisation. Project outputs include UK voluntary standards for wood pellet fuel and combustion appliances, and a database of individuals with an interest in wood pellet fuel.

2016-01-01

We utilize the distribution of PM_2_._5 concentration and population in large cities at the global scale to illustrate the relationship between urbanization and urban air quality. We found: 1) The relationship varies greatly among continents and countries. Large cities in North America, Europe, and Latin America have better air quality than those in other continents, while those in China and India have the worst air quality. 2) The relationships between urban population size and PM_2_._5 concentration in large cities of different continents or countries were different. PM_2_._5 concentration in large cities in North America, Europe, and Latin America showed little fluctuation or a small increasing trend, but those in Africa and India represent a “U” type relationship and in China represent an inverse “U” type relationship. 3) The potential contribution of population to PM_2_._5 concentration was higher in the large cities in China and India, but lower in other large cities. - Highlights: • Urban population and PM_2_._5 concentration varies greatly among regions. • Urban population size increase does not always enhances PM_2_._5 concentration. • Population's potential contribution to PM_2_._5 concentration higher in China. - We utilize the distribution of PM_2_._5 concentration and population in large cities at the global scale to illustrate the relationship between urbanization and urban air quality.

Governance and legitimacy aspects of the UK biofuel carbon and sustainability reporting system

Upham, Paul; Tomei, Julia; Dendler, Leonie

2011-01-01

Biofuel policy has become highly contentious in Europe. In this paper we discuss the governance and legitimacy aspects of the carbon and sustainability system of the UK Renewable Transport Fuel Obligation (RTFO), both before and after implementation of the Renewable Energy Directive. RTFO certification is of a meta-type, being built upon existing certification and labelling schemes, each of which are more or less contested by NGOs. Despite the RTFO being based on these non-state initiatives, so far the concerns of environment and development NGOs and others have not been given serious expression in regulatory terms. Indeed, biofuel policy development in the UK has arguably been unduly non-responsive to critical opinion, given the limited scientific base on biofuel impacts and the reliance of RTFO sustainability certification on non-state actors and schemes. Drawing on documentary evidence, interviews and three sets of literatures - co-production of regulation; post-normal science; and legitimacy of non-state certification and labelling processes - we suggest that until concerned voices are given a stronger expression in UK and EC biofuel policy development, the policy cannot yet be said to have achieved a wide social mandate. - Research highlights: → Interviews with largely non-commercial actors show a high level of concern about EC/UK biofuel policy. → The scientific uncertainties and complexity of biofuels justify inclusive policy development. → Statutory UK and EC biofuel certification will rely heavily on non-state actors and processes.→ EC/UK biofuel certification can learn from legitimisation processes more usually relevant to non-state initiatives.

Factors determining the UK's back-end nuclear fuel cycle strategy and future nuclear systems

International Nuclear Information System (INIS)

Dunn, M.J.; Ainsworth, Z.E.

2002-01-01

Nuclear generating capacity in the UK is static with no units currently under construction. The AGRs and the UK's only PWR, Sizewell B, are operated by British Energy Generation Ltd (BEGL) and British Energy Generation (UK) Ltd (BEG(UK)L), who are subsidiaries of British Energy plc (BE) which was privatised in July 1996. Ownership of the Magnox stations, which were excluded from this privatisation, has now been transferred to BNFL.Government policy on spent fuel management in the UK is that it is for the owners of the spent fuel to decide on the appropriate spent fuel management options, based on their own commercial judgement, subject to meeting the necessary regulatory requirements. The main factors which have predominantly determined UK utility decisions on spent fuel management, to date, have been based on the technical considerations of the spent fuel characteristics, economic attractiveness of the options and at reactor site spent fuel storage capacities. To date, reprocessing has been the dominant form of spent fuel treatment in the UK. Spent fuel storage facilities consist of a mixture of at-reactor stores and large, centralised ponds associated with the reprocessing activities which take place at the Sellafield site. BEGL and BEG(UK)L have contracts for the lifetime arisings of AGR fuel which allow for all AGR spent fuel to be sent to Sellafield for reprocessing or long-term storage. The prompt reprocessing of all Magnox fuel will continue, and spent PWR fuel will continue to be stored at the reactor site in the short to medium term. It is likely that a combination of factors, which are discussed later in this paper, will continue to affect back-end nuclear fuel cycle strategy and future nuclear systems. (author)

The US and UK in the Eyes of English Majors in the Arab World

Full Text Available The current study examines the attitudes of Jordanian female college students whose major is English language and literature towards the United States of America and the United Kingdom. It also looks into the reasons for their held beliefs about the West, the US and UK, in particular. A survey and semi- structured interviews were conducted with forty Muslim female students from various cities and villages in Jordan for this purpose. The selected students are in their final semester in the English program and have completed various courses in language and literature. In these courses, students have been mostly exposed to British and American literature throughout the four year period of their study. The study also examines whether student attitudes towards the West resemble those of the general Arab public. The findings certainly challenge the theory of the “Clash of civilizations.” In fact, the results demonstrate that students have a more favourable opinion of the UK than the US and that this has everything to do with their dissatisfaction with the current American foreign policies and nothing to do with the “American way of life.”

In this study, migration data compiled by the Internal Revenue Serve (IRS) and the US Census Bureau for 2006-07 were used to analyse internal migration patterns using migration and income effectiveness for the counties containing the 25 most populous cities in the United States. The results indicated that both large metropolitan and rural counties have lost population and income due to migration. Small metropolitan and non-metropolitan counties closer to cities gained population and income. Counties in South Florida attracted a large number of higher-income migrants from the largest cities in the US. In the last 13 years, New York, Los Angeles and Chicago, the three most populous cities in the US, had negative migration effectiveness. Suburban areas and second-tier cities continued to attract people from large metropolitan areas.

In order to determine the urokinase (UK) concentration in blood, a radioimmunoassay method was developed, in which a radioactive material labeled with 125 I-Na was used. In this method, the movement of UK in blood and the relationship between the UK concentration and fibrinolytic activity were studied with the following results: 1) The concentration of UK in normal human blood was found to be 6.84 +- 2.53 PKU early in the morning with an apparent daily rythmic fluctuation in concentration. 2) With an intravenous drip of 20,000 to 30,000 PKU, the UK concentration increased 6 to 8 PKU/ml above the early morning value, then in one to two hours it returned to the previous value once again. In some of the cases, a slight, transient decrease occurred. 3) Following the UK drip, UK concentration in the blood and fibrinolytic activity varied in a parallel fashion. Plasminogen and antiplasmin levels were not altered by administration of only 20,000 to 30,000 PKU of UK. Fibrinogen was lowered, but the fluctuation was within the physiological range. (S. Oyama)

The carbon intensity of economic activity, or CO 2 emissions per unit GDP, is a key indicator of the climate impacts of a given activity, business, or region. Although it is well-known that the carbon intensity of countries varies widely according to their level of economic development and dominant industries, few studies have assessed disparities in carbon intensity at the level of cities due to limited availability of data. Here, we present a detailed new inventory of emissions for 337 Chinese cities (every city in mainland China including 333 prefecture-level divisions and 4 province-level cities, Beijing, Tianjin, Shanghai, and Chongqing) in 2013, which we use to evaluate differences of carbon intensity between cities and the causes of those differences. We find that cities' average carbon intensity is 0.84 kg of CO 2 per dollar of gross domestic product (kgCO 2 per $GDP), but individual cities span a large range: from 0.09 to 7.86 kgCO 2 per $GDP (coefficient of variation of 25%). Further analysis of economic and technological drivers of variations in cities' carbon intensity reveals that the differences are largely due to disparities in cities' economic structure that can in turn be traced to past investment-led growth. These patterns suggest that "carbon lock-in" via socio-economic and infrastructural inertia may slow China's efforts to reduce emissions from activities in urban areas. Policy instruments targeted to accelerate the transition of urban economies from investment-led to consumption-led growth may thus be crucial to China meeting both its economic and climate targets.

Open Automated Demand Response (OpenADR), an XML-based information exchange model, is used to facilitate continuous price-responsive operation and demand response participation for large commercial buildings in New York who are subject to the default day-ahead hourly pricing. We summarize the existing demand response programs in New York and discuss OpenADR communication, prioritization of demand response signals, and control methods. Building energy simulation models are developed and field tests are conducted to evaluate continuous energy management and demand response capabilities of two commercial buildings in New York City. Preliminary results reveal that providing machine-readable prices to commercial buildings can facilitate both demand response participation and continuous energy cost savings. Hence, efforts should be made to develop more sophisticated algorithms for building control systems to minimize customer's utility bill based on price and reliability information from the electricity grid.

The link between perceived characteristics of neighbourhood green spaces and adults' physical activity in UK cities: analysis of the EURO-URHIS 2 Study.

Urban dwellers represent half the world's population and are increasing worldwide. Their health and behaviours are affected by the built environment and green areas may play a major role in promoting physical activity, thus decreasing the burden of chronic diseases, overweight and inactivity. However, the availability of green areas may not guarantee healthy levels of physical activity among the urban dwellers. It is therefore necessary to study how the perceived characteristics of green areas affect physical activity. Data from the EURO-URHIS 2 survey of residents of 13 cities across the UK were analyzed and a multivariable model was created in order to assess the association between their perceptions of the green areas in their neighbourhood and their engagement in physical activity. Results were adjusted for age, gender and other potential confounders. Those who felt unable to engage in active recreational activities in their local green spaces were significantly less likely to carry out moderate physical exercise for at least 60 min per week (adjusted OR: 0.50; 95% 0.37-0.68). Availability of green areas within walking distance did not affect engagement in physical activity. Other characteristics such as accessibility and safety may play an important role. This study showed that the presence of green space may not itself encourage the necessary preventative health behaviours to tackle physical inactivity in urban populations. Development of more appropriate green spaces may be required. Further research is needed to shed light on the types green spaces that are most effective. © The Author 2017.

Full Text Available The emerging prototype for a Smart City is one of an urban environment with a new generation of innovative services for transportation, energy distribution, healthcare, environmental monitoring, business, commerce, emergency response, and social activities. Enabling the technology for such a setting requires a viewpoint of Smart Cities as cyber-physical systems (CPSs that include new software platforms and strict requirements for mobility, security, safety, privacy, and the processing of massive amounts of information. This paper identifies some key defining characteristics of a Smart City, discusses some lessons learned from viewing them as CPSs, and outlines some fundamental research issues that remain largely open.

This paper discusses the key findings of the pole-mounted turbine (2.5-6 kWp) component of the UK micro-wind trial. The real world performance of horizontal axis turbines is compared with yield estimates based on site wind speed prediction. The distribution of UK agricultural farms is overlaid with wind resource mapping to estimate the number of potential agricultural farm sites for micro-wind. The yield performance of turbines during the monitoring period was observed to be very close to that predicted by NOABL-MCS wind speed estimates. Based on an installation criterion of a maximum 12 year payback time, with a 6% discount rate and micro-generation feed in tariffs available, there are ∼87,000 farm sites for micro-wind in the UK. If 10% of these farms were to install micro-wind turbines (to a capacity of 48 kWp per farm) this would correspond to a capacity of 418 MWp, with an annual generation yield of 1025 GWh, comparable to that of a large, on shore wind farm in the UK. It should be noted that the feed in tariff considered in this paper is that available in the UK in 2011, which, at 26.7 p/kWh (∼30 Euro cents/kWh) represents a significant subsidy. - Highlights: → Estimated 87,000 agricultural farm sites which are economic for pole mounted micro-wind in the UK. → Good agreement between NOABL-MCS yield prediction and site measurements for UK pole mounted turbines. → Pole mounted micro-wind has favourable economics under current UK feed in tariffs.

Recent trends and future opportunities in UK bioenergy: Maximising biomass penetration in a centralised energy system

International Nuclear Information System (INIS)

Perry, Miles; Rosillo-Calle, Frank

2008-01-01

In the past decade or so, the British government policy support for renewable energy (RE) has been at the core of the rapid growth of bioenergy in the UK rather than genuine market forces. Policy support has been through various instruments which are discussed in this paper, with particular attention given to co-firing and transport fuels. The UK energy sector remains dominated by large fossil fuels power plants and this does not facilitate the introduction of RE. One exception is co-firing which in 2005 generated 2.5 TWh. Another area of considerable potential and interest is the use of biofuels (biodiesel and bioethanol) for transport, although current contribution remains still very small (0.18% of total fuel sales in 2005). In 2005, the UK used 1.4 million tonnes of biomass in co-firing, mostly imported, while considerable potential exists for further expansion should policy incentives continue. It is also generally accepted that the UK will have to rely largely on imports if it is to fulfil its 5% minimum biofuel blends agreed for 2010 and 10% in 2015. Both sectors present excellent opportunities for international bioenergy trade, despite the domestic production potential, as demonstrated in this paper. In addition, the forthcoming introduction of carbon and sustainability reporting should incentivise greater reporting along the supply chain, encouraging trade in the most sustainable biofuels.

Supporting UK adaptation: building services for the next set of UK climate projections

Science.gov (United States)

Fung, Fai; Lowe, Jason

2016-04-01

As part of the Climate Change Act 2008, the UK Government sets out a national adaptation programme to address the risks and opportunities identified in a national climate change risk assessment (CCRA) every five years. The last risk assessment in 2012 was based on the probabilistic projections for the UK published in 2009 (UKCP09). The second risk assessment will also use information from UKCP09 alongside other evidence on climate projections. However, developments in the science of climate projeciton, and evolving user needs (based partly on what has been learnt about the diverse user requirements of the UK adaptation community from the seven years of delivering and managing UKCP09 products, market research and the peer-reviewed literature) suggest now is an appropriate time to update the projections and how they are delivered. A new set of UK climate projections are now being produced to upgrade UKCP09 to reflect the latest developments in climate science, the first phase of which will be delivered in 2018 to support the third CCRA. A major component of the work is the building of a tailored service to support users of the new projections during their development and to involve users in key decisions so that the projections are of most use. We will set out the plan for the new climate projections that seek to address the evolving user need. We will also present a framework which aims to (i) facilitate the dialogue between users, boundary organisations and producers, reflecting their different decision-making roles (ii) produce scientifically robust, user-relevant climate information (iii) provide the building blocks for developing further climate services to support adaptation activities in the UK.

Autopsy findings in bodies repatriated to the UK.

Williams, Edward John; Davison, Andrew

2014-07-01

Following the death of a British National on foreign soil, a primary investigation is conducted by the authorities of that country; HM Coroner and the United Kingdom police have no jurisdiction to conduct investigations abroad. Upon repatriation of a body, the legal investigation in the UK remains largely unchanged since the publication of the "harmonisation of medico-legal autopsy rules" (1999) and the passing of the Coroners and Justice Act (2009). We identified 44 cases within a 10-year period. An invasive autopsy had been performed abroad in 25 cases; an autopsy report was received prior to UK autopsy in one case. Seven cases showed incomplete evisceration; the absence of part or whole organs was recorded in 11 cases. Toxicology was performed abroad in five cases. Recurring technical difficulties related chiefly to embalming, including difficulty with dissection and noxious fumes. When an autopsy had been performed abroad, the time to UK inquest was prolonged by an average of seven months. A verdict of unlawful killing was returned in nine cases. The discussion expands on these issues, and attempts to offer reasoned explanation where possible. Two cases are used as exemplars to highlight difficulties to both the pathologist and Coroner. This casework remains rare but the potential problems include: absence of tissue; lack of information; technical difficulties; and a disproportionately high number of unlawful killings, making clear the need for experience and caution when making the post mortem examination.

Nuclear power and the UK

International Nuclear Information System (INIS)

Murphy, St.

2009-01-01

This series of slides describes the policy of the UK government concerning nuclear power. In January 2008 the UK Government published the White Paper on the Future of Nuclear Power. The White Paper concluded that new nuclear power stations should have a role to play in this country's future energy mix. The role of the Government is neither to build nuclear power plants nor to finance them. The White Paper set out the facilitative actions the Government planned to take to reduce regulatory and planning risks associated with investing in new nuclear power stations. The White Paper followed a lengthy period of consultation where the UK Government sought a wide variety of views from stakeholders and the public across the country on the future of nuclear power. In total energy companies will need to invest in around 30-35 GW of new electricity generating capacity over the next two decades. This is equivalent to about one-third of our existing capacity. The first plants are expected to enter into service by 2018 or sooner. The Office for Nuclear Development (OND) has been created to facilitate new nuclear investment in the UK while the Nuclear Development Forum (NDF) has been established to lock in momentum to secure the long-term future of nuclear power generation in the UK.

Small cities in generalized urbanization and global crisis

Directory of Open Access Journals (Sweden)

Horacio Capel

2010-06-01

Full Text Available Today, referring to the small city means talking about a space that can be connected in every way to the rest of the World, and yet features a particular social and morphologic environment, which is different to that of large cities, and that may therefore be rather attractive. In the current situation of Generalized Urbanization, the meaning of middle and small cities is changing, with respect to what happened in the past. While it could long be asserted that urban growth was a very positive fact (the larger, the better, since the decade of the sixties, when the controversy about growth limits was raised, this perspective began to change. Nowadays it is certainly true that, in some cases, the lesser that growth is, the better, and in every situation, the most balanced it is, the better. Today, small cities may have significant advantages over large ones: they can be innovative, hold education centers, enjoy access to knowledge and culture, and be well communicated with areas of dynamic economic development. And besides all of this, they can be very agreeable places to live in.

To assess the degree of implementation of the Directly Observed Treatment, Short-course - DOTS for tuberculosis (TB) in a large city. Assessment of the implementation of the logic model, whose new cases of infectious pulmonary TB were recruited from specialized clinics and followed-up in basic health units. The judgment matrix covering the five components of the DOTS strategy were used. The result of the logic model indicates DOTS was partially implemented. In external, organizational and implementation contexts, the DOTS strategy was partially implemented; and, the effectiveness was not implemented. The partial implementation of the DOTS strategy in the city of Manaus did not reflect in TB control compliance, leading to low effectiveness of the program. Avaliar o grau de implantação da estratégia de tratamento diretamente observado (Directly Observed Treatment, Short-course - DOTS) para tuberculose (TB) em um município de grande porte. Avaliação de implantação por meio de modelo lógico, cujos casos novos de TB pulmonar bacilífera foram recrutados em ambulatórios especializados e acompanhados nas unidades básicas de saúde. Utilizou-se matriz de julgamento que abrange os cinco componentes da estratégia DOTS. O resultado do modelo lógico indica DOTS implantada parcialmente. Nos contextos externo, organizacional e de implantação, a estratégia DOTS está implantada parcialmente; e, na efetividade não está implantada. A implantação parcial da estratégia DOTS, na cidade de Manaus, reflete na não conformidade do controle da TB, levando à baixa efetividade do programa.

To investigate hygiene practices of caterers at large events in order to: support the production of guidance on catering at such events; to compare hygiene standards at weekends with other times in the week; and to learn lessons in preparation for the London Olympics in 2012. UK-wide study of caterers at large events, including questionnaires on hygiene procedures and microbiological examination of food, water and environmental samples. In total, 1364 samples of food, water, surface swabs and cloths were collected at 139 events, by local authority sampling officers, and transported to laboratories for microbiological analysis. Eight percent of food samples were of an unsatisfactory quality, and a further 2% contained potentially hazardous levels of Bacillus spp. A significantly higher proportion of unsatisfactory food samples were taken from vendors without adequate food safety procedures in place. Fifty-two percent of water samples, 38% of swabs and 71% of cloths were also unsatisfactory. The majority of samples (57%) were collected on Saturdays, Sundays or bank holidays. Environmental swab results were significantly poorer at weekends compared with other days of the week. This study reinforces the fact that food hygiene is a continuing cause for concern in mobile vendors, and indicates a need for an ongoing programme of training and monitoring of caterers in preparation for the London Olympics.

Studying the urban thermal environment under a human-biometeorological point of view: The case of a large coastal metropolitan city, Athens

Science.gov (United States)

Katavoutas, George; Georgiou, Giorgos K.; Asimakopoulos, Dimosthenis N.

2015-01-01

The thermal environment in modern cities has become potentially unfavorable and harmful for its residents, as a result of urbanization and industrialization. Exposure to these extreme thermal conditions increases the heat stress of people in cities considerably. In this context, the present study aims to investigate the urban thermal environment of the large coastal metropolitan city of Athens, in a human-biometeorologically significant way, utilizing the thermo-physiological assessment index PET. The analysis was based on three hour measurements derived from three-year datasets (2006-2009), at 12 monitoring sites located in the urban complex of Athens, on its boundaries and beyond them. The differences of PET values have been investigated in order to attribute urban and exurban thermal characteristics to the considered sites. The frequency and spatial distribution of PET as well as the urban/rural differences of PET have also been analyzed. Finally, a trend analysis has been applied in order to detect possible PET trends by employing long-term recording data (1985-2008). In terms of thermal human-biometeorological conditions, the analysis reveals that among the considered stations, those located inside the urban complex and the industrialized area present urban thermal characteristics, regardless the fact that they are installed either in a park and on a hill or at an open field. The spatial distribution of PET, at 0200 LST, shows a difference of about 3 to 4 °C, on the main axis of the city (SSW-NNE) in the summer period, while the difference exceeds 2.5 °C in the winter period. In general, cooler (less warm) thermal perception is observed at the north/northeast sites of the city as well as at the areas beyond the eastern boundaries of it. The PET differences between urban and rural sites hold a positive sign, except of those at 0500 LST and at 0800 LST. The highest differences are noted at 1400 LST and the most intense of them is noticed in the summer period

EXPERIENCE OF USING ADVANCED INFORMATION TECHNOLOGIES IN TRAINING FUTURE TRANSLATORS IN UK UNIVERSITIES

Full Text Available The quality of teaching is not only to use the Internet or e-learning. The novelty of the information and communication technology is to change the orientation of training, the transition to the creation of online and e-learning systems, but also remains an unsolved problem of adaptation of new materials. With IT students develop creativity, independence, professionalism. Interactive technologies provide various kinds of user interaction (sound, images, animations, etc. and is a basic tool for the creation of computer training programs. The synthesis of traditional and modern information technology is based on the activity- when learning activities are the subject of training and help to create an overview of the professional activities of an interpreter as a purposeful, active, long-term process of learning. Using an interdisciplinary approach makes it possible to seamlessly integrate the knowledge of linguistics and computer science, linguistics and psychology. The purpose of this paper is the analysis of experience in the use of new information technologies in the training of future translators in UK universities. In this research we identified the most common programs used in the preparation of translators, substantiated the possibility of their application, named the city and universities in the UK where such training is carried out.

Seasonal UK Drought Forecasting using Statistical Methods

Science.gov (United States)

Richardson, Doug; Fowler, Hayley; Kilsby, Chris; Serinaldi, Francesco

2016-04-01

In the UK drought is a recurrent feature of climate with potentially large impacts on public water supply. Water companies' ability to mitigate the impacts of drought by managing diminishing availability depends on forward planning and it would be extremely valuable to improve forecasts of drought on monthly to seasonal time scales. By focusing on statistical forecasting methods, this research aims to provide techniques that are simpler, faster and computationally cheaper than physically based models. In general, statistical forecasting is done by relating the variable of interest (some hydro-meteorological variable such as rainfall or streamflow, or a drought index) to one or more predictors via some formal dependence. These predictors are generally antecedent values of the response variable or external factors such as teleconnections. A candidate model is Generalised Additive Models for Location, Scale and Shape parameters (GAMLSS). GAMLSS is a very flexible class allowing for more general distribution functions (e.g. highly skewed and/or kurtotic distributions) and the modelling of not just the location parameter but also the scale and shape parameters. Additionally GAMLSS permits the forecasting of an entire distribution, allowing the output to be assessed in probabilistic terms rather than simply the mean and confidence intervals. Exploratory analysis of the relationship between long-memory processes (e.g. large-scale atmospheric circulation patterns, sea surface temperatures and soil moisture content) and drought should result in the identification of suitable predictors to be included in the forecasting model, and further our understanding of the drivers of UK drought.

The taxation of UK oil and gas production. Why the windfalls got away

2010-01-01

Starting with evidence that United Kingdom Continental Shelf oil and gas companies have benefitted very disproportionately from the recent period of extraordinarily high oil prices, this paper traces the history of this weakness in the UK's petroleum fiscal regime. Evidence is provided that the progressive relaxations in the UK's petroleum fiscal regime in 1983, 1987-1988 and 1993 were: largely unnecessary to stimulate the development of new, smaller, 'marginal' fields; misguided in their assumption that such fields were more costly to develop than earlier counterparts or larger contemporary fields; and impotent compared with the effects of oil price movements. The paper concludes with a conceptualisation which illuminates why these failures of policy were not just random: they emerged from the UK's 'non-proprietorial' stance with respect to the country's oil and gas resources, a stance which assumes responsibility for oil company profitability and vainly tries to counter market forces at the expense of government revenues.

A new Callisto solar radio spectrometer system has recently been installed and set into operation at Acre Road Observatory, a facility of University of Glasgow, Scotland UK. There has been an Observatory associated with Glasgow University since 1757, and they presently occupy two different sites. The main observatory ('Acre Road') is close to the Garscube Estate on the outskirts of the city of Glasgow. The outstation ('Cochno', housing the big 20 inch Grubb Parsons telescope) is located farther out at a darker site in the Kilpatrick Hills. The Acre Road Observatory comprises teaching and research labs, a workshop, the main dome housing the 16 inch Meade, the solar dome, presently housing the 12 inch Meade, a transit house containing the transit telescope, a 3m HI radio telescope and a 408 MHz pulsar telescope. They also have 10 and 8 inch Meade telescopes and several 5 inch Celestron instruments. There is a small planetarium beneath the solar dome. The new Callisto instrument is mainly foreseen for scientific solar burst observations as well as for student projects and for 'bad-weather' outreach activities.

Following nearly two decades of increasing tuberculosis in the UK, TB incidence decreased by 32% from 2011 to 2015. Explaining this reduction is crucial to informing ongoing TB control efforts. We stratified TB cases notified in the UK and TB cases averted in the UK through pre-entry screening (PES) between 2011 and 2015 by country of birth and time since arrival. We used population estimates and migration data to establish denominators, and calculated incidence rate ratios (IRRs) between 2011 and 2015. We calculated the contribution of changing migrant population sizes, PES and changes in TB rates to the reduction in TB notifications. TB IRRs fell in all non-EU migrant and UK-born populations between 2011 and 2015 (0.61; 95%  CI 0.59 to 0.64 and 0.78; 0.73 to 0.83 respectively), with the greatest decrease in recent non-EU migrants (0.54; 0.48 to 0.61). 61.9% of the reduction in TB notifications was attributable to decreases in TB rates, 33.4% to a fall in the number of recent/mid-term non-EU migrants and 11.4% to PES. A small increase in notifications in EU-born migrants offset the reduction by 6.6%. Large decreases in TB rates in almost all populations accounted for the majority of the reduction in TB notifications, providing evidence of the impact of recent interventions to improve UK TB control. The particularly large decrease in TB rates in recent non-EU migrants provides evidence of the effectiveness of screening interventions that target this population. These findings will inform ongoing improvements to TB control. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018. All rights reserved.

A validated geographic search filter for the retrieval of research about the United Kingdom (UK) from bibliographic databases had not previously been published. To develop and validate a geographic search filter to retrieve research about the UK from OVID medline with high recall and precision. Three gold standard sets of references were generated using the relative recall method. The sets contained references to studies about the UK which had informed National Institute for Health and Care Excellence (NICE) guidance. The first and second sets were used to develop and refine the medline UK filter. The third set was used to validate the filter. Recall, precision and number-needed-to-read (NNR) were calculated using a case study. The validated medline UK filter demonstrated 87.6% relative recall against the third gold standard set. In the case study, the medline UK filter demonstrated 100% recall, 11.4% precision and a NNR of nine. A validated geographic search filter to retrieve research about the UK with high recall and precision has been developed. The medline UK filter can be applied to systematic literature searches in OVID medline for topics with a UK focus. © 2017 Crown copyright.

Joint Genomic Prediction of Canine Hip Dysplasia in UK and US Labrador Retrievers

Directory of Open Access Journals (Sweden)

Stefan M. Edwards

2018-03-01

Full Text Available Canine hip dysplasia, a debilitating orthopedic disorder that leads to osteoarthritis and cartilage degeneration, is common in several large-sized dog breeds and shows moderate heritability suggesting that selection can reduce prevalence. Estimating genomic breeding values require large reference populations, which are expensive to genotype for development of genomic prediction tools. Combining datasets from different countries could be an option to help build larger reference datasets without incurring extra genotyping costs. Our objective was to evaluate genomic prediction based on a combination of UK and US datasets of genotyped dogs with records of Norberg angle scores, related to canine hip dysplasia. Prediction accuracies using a single population were 0.179 and 0.290 for 1,179 and 242 UK and US Labrador Retrievers, respectively. Prediction accuracies changed to 0.189 and 0.260, with an increased bias of genomic breeding values when using a joint training set (biased upwards for the US population and downwards for the UK population. Our results show that in this study of canine hip dysplasia, little or no benefit was gained from using a joint training set as compared to using a single population as training set. We attribute this to differences in the genetic background of the two populations as well as the small sample size of the US dataset.

The Swedish-Danish Barsebaeck committee suggested in June 1983 that a demographic comparison of the Barsebaeck nuclear power plant be made with plants situated near other large cities and national borders. Sixteen other nuclear power plants: 13 in Western Europe, 2 in USA and 1 in Canada were chosen for the comparison. For five discrete distances out to 50 km, the population distributions have been found and compared. In addition the positions, related to the plants, of institutions, administrative centres, communication centres and other plants of public importance within the country or in neughbouring countries are described. Finally, the details of special agreements are given together with negotiations between neighbouring countries or internationally about nuclear power related matters. These include alarm and emergency procedures and agreements about liability in case of an accident in a neighbouring country. (author)

Large Item Disposal At The Drigg Low Level Waste Repository, United Kingdom

International Nuclear Information System (INIS)

Griffiths, Steve

2012-01-01

Currently the UK operates only one repository for low level radioactive waste, the LLWR near Drigg in Cumbria. It is located on the West Cumbrian coast near the village of Drigg. LLWR is designed for the management of solid LLW and has operated as the principal national disposal facility for LLW since 1959. LLWR is managed and operated on behalf of the Nuclear Decommissioning Authority (NDA) by UK Nuclear Waste Management Ltd. (UKNWM), parent body of LLW Repository Ltd. UKNWM is a consortium led by URS, Studsvik and AREVA. Waste is accepted at LLWR based on conditions for acceptance (1). Although there is some history of disposal of non-containerised 'large items' at the Drigg site these are anecdotally described as 'not quite fitting into an ISO container (2)' and enquiries indicate that their disposal was restricted to the legacy times when items were tumble-tipped into open trenches at the site, a practise now long ceased. The feasibility of true single large item disposal at the LLWR presents complex problems arising from the poor suitability of both rail and road infrastructure in UK. LLWR is serviced both by road and rail links. The static weight of large items being taken nominally as up to ∼300 metric tons would not necessarily preclude transportation by rail but the practicalities of this route are limited. The ageing rail infrastructure includes numerous tunnels, bridges and sections of line with overhead electrification. All these would require either careful justification or significant work to ensure the safe transit of large loads. Nuclear facilities in UK are by design in remote locations, not all of which are serviced by rail connections and the rail network itself has evolved to service inter-city transportation rather than heavy freight and as such tends to route through town centres, exacerbating the tunnel, bridge and pantograph concerns already identified. Within only a few miles of the LLWR itself there are requirements to pass both over and

Implications of sustainability constraints on UK bioenergy development: Assessing optimistic and precautionary approaches with UK MARKAL

International Nuclear Information System (INIS)

McDowall, Will; Anandarajah, Gabrial; Dodds, Paul E.; Tomei, Julia

2012-01-01

Bioenergy is an important renewable energy resource. However, assessments of the future of bioenergy are beset with uncertainty and contested values, suggesting that a precautionary approach to bioenergy resource development may be warranted. This paper uses UK MARKAL to examine the implications of adopting a precautionary approach to bioenergy development in the UK. The paper reports a detailed review of UK bioenergy resources and sustainability constraints, and develops precautionary and optimistic resource scenarios. The paper then examines the implications of these scenarios using the energy systems model MARKAL, finding that a precautionary approach adds to the cost of decarbonisation, but does not significantly alter the optimal technology mix. In particular, biomass and co-firing CCS emerge as optimal technologies across scenarios. The question of UK land availability for bioenergy production is highlighted within the paper. With less land available for bioenergy production, the costs of decarbonisation will rise; whereas if more land is available for bioenergy, then less land is available for either food production or ecosystem conservation. This paper quantifies one side of this trade-off, by estimating the additional costs incurred when UK land availability for bioenergy production is constrained. - Highlights: ► We assess UK bioenergy resources under optimistic and precautionary approaches. ► Using MARKAL, we find that sustainability constraints add to decarbonisation costs. ► Preferred use of bioenergy is similar in optimistic and precautionary cases. ► Best use of bioenergy is heat and power, not transport, if CCS is available. ► The marginal value of additional land availability to the energy system is high.

An adaptive large neighborhood search heuristic for Two-Echelon Vehicle Routing Problems arising in city logistics

Science.gov (United States)

Hemmelmayr, Vera C.; Cordeau, Jean-François; Crainic, Teodor Gabriel

2012-01-01

In this paper, we propose an adaptive large neighborhood search heuristic for the Two-Echelon Vehicle Routing Problem (2E-VRP) and the Location Routing Problem (LRP). The 2E-VRP arises in two-level transportation systems such as those encountered in the context of city logistics. In such systems, freight arrives at a major terminal and is shipped through intermediate satellite facilities to the final customers. The LRP can be seen as a special case of the 2E-VRP in which vehicle routing is performed only at the second level. We have developed new neighborhood search operators by exploiting the structure of the two problem classes considered and have also adapted existing operators from the literature. The operators are used in a hierarchical scheme reflecting the multi-level nature of the problem. Computational experiments conducted on several sets of instances from the literature show that our algorithm outperforms existing solution methods for the 2E-VRP and achieves excellent results on the LRP.

In this paper, we propose an adaptive large neighborhood search heuristic for the Two-Echelon Vehicle Routing Problem (2E-VRP) and the Location Routing Problem (LRP). The 2E-VRP arises in two-level transportation systems such as those encountered in the context of city logistics. In such systems, freight arrives at a major terminal and is shipped through intermediate satellite facilities to the final customers. The LRP can be seen as a special case of the 2E-VRP in which vehicle routing is performed only at the second level. We have developed new neighborhood search operators by exploiting the structure of the two problem classes considered and have also adapted existing operators from the literature. The operators are used in a hierarchical scheme reflecting the multi-level nature of the problem. Computational experiments conducted on several sets of instances from the literature show that our algorithm outperforms existing solution methods for the 2E-VRP and achieves excellent results on the LRP.

Planning forms for 20th-century cities

Survey report:In the next 30 years, additional millions of people will live in either entirely new cities or extensions of existing ones, extensions so large as to constitute virtually new cities. A discussion of the basic functions of cities leads to a framework of rules for new ones: 1.5 km width between periphery roads; local roads at intervals of approximately 600 m; a central line of public transport; rear road access by cul-de-sacs to shops and public buildings; pedestrian main center and local centers intersecting every 600 m and at least partly arcaded; open space; a reasonably high density; and new construction only next to parts already completed.

1977-01-01

Enriched uranium metal fuel irradiated in the Dounreay Fast Reactor has been reprocessed and refabricated in plants specifically designed for the purpose in the U.K. since 1961. Efficient and reliable fuel recycle is essential to the development of a plutonium based fast reactor system and the importance of establishing at an early stage fast reactor fuel reprocessing has been reinforced by current world difficulties in reprocessing high burn-up thermal reactor oxide fuel. In consequence, the U.K. has decided to reprocess irradiated fuel from the 250 MW(E) Prototype Fast Reactor as an integral part of the fast reactor development programme. Flowsheet and equipment development work for the small scale fully active demonstration plant have been carried out over the past 5 years and the plant will be commissioned and ready for active operation during 1977. In parallel, a comprehensive waste management system has been developed and installed. Based on this development work and the information which will arise from active operation of the plant a parallel development programme has been initiated to provide the basis for the design of a large scale fast reactor fuel reprocessing plant to come into operation in the late 1980s to support the projected U.K. fast reactor installation programme. The paper identifies the important differences between fast reactor and thermal reactor fuel reprocessing technologies and describes some of the development work carried out in these areas for the small scale P.F.R. fuel reprocessing operation. In addition, the development programme in aid of the design of a larger scale fast reactor fuel reprocessing plant is outlined and the current design philosophy is discussed

Photorealistic large-scale urban city model reconstruction.

The rapid and efficient creation of virtual environments has become a crucial part of virtual reality applications. In particular, civil and defense applications often require and employ detailed models of operations areas for training, simulations of different scenarios, planning for natural or man-made events, monitoring, surveillance, games, and films. A realistic representation of the large-scale environments is therefore imperative for the success of such applications since it increases the immersive experience of its users and helps reduce the difference between physical and virtual reality. However, the task of creating such large-scale virtual environments still remains a time-consuming and manual work. In this work, we propose a novel method for the rapid reconstruction of photorealistic large-scale virtual environments. First, a novel, extendible, parameterized geometric primitive is presented for the automatic building identification and reconstruction of building structures. In addition, buildings with complex roofs containing complex linear and nonlinear surfaces are reconstructed interactively using a linear polygonal and a nonlinear primitive, respectively. Second, we present a rendering pipeline for the composition of photorealistic textures, which unlike existing techniques, can recover missing or occluded texture information by integrating multiple information captured from different optical sensors (ground, aerial, and satellite).

Changes in O3 and NO2 due to emissions from Fracking in the UK.

Poor air quality is a problem that affects millions of people around the world. Understanding the driving forces behind air pollution is complicated as the precursor gases which combine to produce air pollutants react in a highly non-linear manner and are subject to a range of atmospheric transport mechanisms compounded by the weather. A great deal of money has been spent on mitigating air pollution and so it's important to assess the impacts that new technologies that emit air pollutant precursors may have on local and regional air pollution. One of the most highly discussed new technologies that could impact air quality is the adoption of wide-scale hydraulic fracturing or "fracking" for natural gas. Indeed in regions of the USA where fracking is commonplace large levels of ozone (O3 - a key air pollutant) have been observed and attributed directly to the fracking process. In this study, a numerical modelling framework was used to assess possible impacts of fracking in the UK where at present no large scale fracking facilities are in operation. A number of emissions scenarios were developed for the principle gas phase air pollution precursors: the oxides of nitrogen (NOx) and volatile organic compounds (VOCs). These emissions scenarios were then used in a state-of-the-art numerical air quality model (the UK Met Office operational air quality forecasting model AQUM) to determine potential impacts related to fracking on UK air quality. Comparison of base model results and observations for the year 2013 of NOx, O3 and VOCs from the UK Automatic Urban and Rural Network (AURN) showed that AQUM has good skill at simulating these gas phase air pollutants (O3 r=0.64, NMGE=0.3; NO2 r=0.62, NMGE=0.51). Analysis of the simulations with fracking emissions demonstrate that there are large changes in 1hr max NO2 (11.6±6.6 ppb) with modest increases in monthly mean NO2, throughout the British Isles (150±100 ppt). These results highlight that stringent measures should be

Review of Tidal Lagoon Technology and Opportunities for Integration within the UK Energy System

Full Text Available The number of distributed resources for renewable energy installed worldwide has been increasing rapidly in the last decade, and the great majority of these installations consist of solar panels and wind turbines. Other renewable sources of energy are not exploited to the same level: for instance, tidal energy is still a minute portion of the global energy capacity, in spite of the large amount of potential energy stored in tidal waves, and of the successful experience of the few existing plants. The world’s second largest tidal range occurs in the UK but at the moment tidal installations in this country are limited to a few prototypes. More recently, there has been a renewed interest in harnessing tidal energy in the UK, and a few tidal lagoon projects have been evaluated by the UK government. This paper provides an overview of the historical and current developments of tidal plants, a description of operation of tidal lagoons, challenges and opportunities for their integration within the UK energy systems and solutions to improve the dispatchability of tidal energy. The concepts described in the paper are applied to a tidal project proposed for South Wales.

Indoor air quality: a UK perspective

Wadge, A.

1995-01-01

Outdoor air quality has generally improved in the UK over the last 2 decades but during this period changing conditions within the home have tended to reduce ventilation and increase the opportunity for accumulation of undesirable levels of indoor air pollutants. Information obtained from laboratory and epidemiological studies suggest that indoor air pollutants are an important cause of avoidable morbidity and mortality in the UK. This paper reviews the major indoor air pollutants of concern in the UK and considers some of the special issues relevant to indoor environment. (author) 3 figs., 37 refs

Integrated planning aimed at sustainability city logistics solutions

Full Text Available The main objective of city logistics system is sustainability, or efficiency, wide acceptability, environmental protection and safety. On the other hand, the city logistics system is very complex. It is characterized by a large number of participants, with different, usually conflicting goals and complex interactions. In addition, the system of city logistics is part of a wider system of the town, the region, and there are complex interactions with the external environment. The system depends on the specific characteristics of the city, affects other forms of urban mobility and is subject to the policies of higher rank (regional, national policy. Given the exceptional complexity, sustainable city logistics solution requires an integrated approach in all phases of planning, from stages of problem identification, definition of alternative solutions and effects assessment, to implementation and by exploitation. In this way, the solution of city logistics is becoming widely accepted and not only affects the efficiency of the socio-economic system of town, already on the sustainability of the whole region.

2018-01-01

Full Text Available In recent years, more rural areas are becoming urban areas accompanied by escalation of logistics activities. Unlike passenger transport, the planning, policy and control of freight transport in developing countries have not been integrated into a reliable and efficient logistics system. Therefore, generating city logistics profile is necessary in order to support the planning of urban logistics system. This study aims to establish a logistics profile of Yogyakarta city, Indonesia, by dividing urban zones into several homogeneous groups, judging from several aspects, including city area features, product characteristics and agents/delivery profile. Logistics profile variables were calculated based on administrative boundaries, resulting in 45 areas to be investigated. Profiles were matched in groups of homogeneous stores (A, large commercial stores (C and residential areas with local trade (D,with one overlapping profile, i.e. profile A and profile D, in some locations in the middle of the city.

Previous studies of environmental justice in Canadian cities have linked lower socioeconomic status to greater air pollution exposures at coarse geographic scales, (i.e., Census Tracts). However, studies that examine these associations at finer scales are less common, as are comparisons among cities. To assess differences in exposure to air pollution among socioeconomic groups, we assigned estimates of exposure to ambient nitrogen dioxide (NO2), a marker for traffic-related pollution, from city-wide land use regression models to respondents of the 2006 Canadian census long-form questionnaire in Toronto, Montreal, and Vancouver. Data were aggregated at a finer scale than in most previous studies (i.e., by Dissemination Area (DA), which includes approximately 400-700 persons). We developed simultaneous autoregressive (SAR) models, which account for spatial autocorrelation, to identify associations between NO2 exposure and indicators of social and material deprivation. In Canada's three largest cities, DAs with greater proportions of tenants and residents who do not speak either English or French were characterised by greater exposures to ambient NO2. We also observed positive associations between NO2 concentrations and indicators of social deprivation, including the proportion of persons living alone (in Toronto), and the proportion of persons who were unmarried/not in a common-law relationship (in Vancouver). Other common measures of deprivation (e.g., lone-parent families, unemployment) were not associated with NO2 exposures. DAs characterised by selected indicators of deprivation were associated with higher concentrations of ambient NO2 air pollution in the three largest cities in Canada. Crown Copyright © 2016.

The Uses of Big Data in Cities.

Science.gov (United States)

Bettencourt, Luís M A

2014-03-01

There is much enthusiasm currently about the possibilities created by new and more extensive sources of data to better understand and manage cities. Here, I explore how big data can be useful in urban planning by formalizing the planning process as a general computational problem. I show that, under general conditions, new sources of data coordinated with urban policy can be applied following fundamental principles of engineering to achieve new solutions to important age-old urban problems. I also show that comprehensive urban planning is computationally intractable (i.e., practically impossible) in large cities, regardless of the amounts of data available. This dilemma between the need for planning and coordination and its impossibility in detail is resolved by the recognition that cities are first and foremost self-organizing social networks embedded in space and enabled by urban infrastructure and services. As such, the primary role of big data in cities is to facilitate information flows and mechanisms of learning and coordination by heterogeneous individuals. However, processes of self-organization in cities, as well as of service improvement and expansion, must rely on general principles that enforce necessary conditions for cities to operate and evolve. Such ideas are the core of a developing scientific theory of cities, which is itself enabled by the growing availability of quantitative data on thousands of cities worldwide, across different geographies and levels of development. These three uses of data and information technologies in cities constitute then the necessary pillars for more successful urban policy and management that encourages, and does not stifle, the fundamental role of cities as engines of development and innovation in human societies.

Risk reduction in a changing insurance climate: examples from the US and UK

Science.gov (United States)

Horn, Diane; McShane, Michael

2015-04-01

Coastal cities face a range of increasingly severe challenges as sea level rises, and adaptation to future flood risk will require more than structural defences. Many cities will not be able to rely solely on engineering structures for protection and will need to develop a suite of policy responses to increase their resilience to impacts of rising sea level. Insurance can be used as a risk-sharing mechanism to encourage adaptation to sea level rise, using pricing or restrictions on availability of cover to discourage new development in flood risk areas or to encourage the uptake of flood resilience measures. We draw on flood insurance policy lessons learned from the United States and the United Kingdom to propose risk-sharing among private insurers/reinsurers, government, and policyholders to alleviate major issues of the current programs, while still maintaining a holistic approach to managing flood risk. The UK and the US are almost polar opposites in the way flood insurance is implemented. Flood insurance in the US is fully public and in the UK fully private; however, in both countries the participants feel that the established system is unsustainable. In the US, flood coverage is excluded from property policies provided by private insurers, and is only available through the National Flood Insurance Program (NFIP), with the federal government acting as insurer of last resort. Flood risk reduction has been part of the NFIP remit since the introduction of the program in 1968. Following massive payments for flood claims related primarily to Hurricanes Katrina and Sandy, the NFIP is approximately 26 billion in debt, prompting calls to bring private insurance back into the flood insurance business. Two major Congressional modifications to the NFIP in 2012 and 2014 have pushed the contradictory goals of fully risk-based, yet affordable premiums. The private market has not been significantly involved in a risk-bearing role, but that is changing as private insurers

CityGML - Interoperable semantic 3D city models

Science.gov (United States)

Gröger, Gerhard; Plümer, Lutz

2012-07-01

CityGML is the international standard of the Open Geospatial Consortium (OGC) for the representation and exchange of 3D city models. It defines the three-dimensional geometry, topology, semantics and appearance of the most relevant topographic objects in urban or regional contexts. These definitions are provided in different, well-defined Levels-of-Detail (multiresolution model). The focus of CityGML is on the semantical aspects of 3D city models, its structures, taxonomies and aggregations, allowing users to employ virtual 3D city models for advanced analysis and visualization tasks in a variety of application domains such as urban planning, indoor/outdoor pedestrian navigation, environmental simulations, cultural heritage, or facility management. This is in contrast to purely geometrical/graphical models such as KML, VRML, or X3D, which do not provide sufficient semantics. CityGML is based on the Geography Markup Language (GML), which provides a standardized geometry model. Due to this model and its well-defined semantics and structures, CityGML facilitates interoperable data exchange in the context of geo web services and spatial data infrastructures. Since its standardization in 2008, CityGML has become used on a worldwide scale: tools from notable companies in the geospatial field provide CityGML interfaces. Many applications and projects use this standard. CityGML is also having a strong impact on science: numerous approaches use CityGML, particularly its semantics, for disaster management, emergency responses, or energy-related applications as well as for visualizations, or they contribute to CityGML, improving its consistency and validity, or use CityGML, particularly its different Levels-of-Detail, as a source or target for generalizations. This paper gives an overview of CityGML, its underlying concepts, its Levels-of-Detail, how to extend it, its applications, its likely future development, and the role it plays in scientific research. Furthermore, its

Based on the linear relationship between solar radiation and sunshine duration, the Angstrom model is widely used to estimate solar radiation from routinely observed meteorological variables for energy exploitation. However, the relationship may have changed in quickly developing regions in the recent decades under global “dimming” and “brightening” context, with increasing aerosols due to industrial pollutions. Solar radiation stations under different climate conditions in six large cities in China are selected to test this hypothesis. Analysis of the related meteorological items shows that Guiyang has the lowest solar radiation with the average annual value of 10.5 MJm −2 d −1 , while Lhasa on the Tibetan Plateau has the highest of 20.1 MJm −2 d −1 . Both radiation and sunshine hours decreased from 1961 to 2010, but at different rates. A moving linear regression method is used to investigate the changes in the relationship between radiation and sunshine duration, the results indicate an abrupt change in the correlation coefficients in 1980–1990s, which can be attributed to the aerosol load resulting from air pollution caused by the industrial development in 1980s under China's Open Door Policy. The sky condition has been changing from clean to dirty, thus the relationship between solar radiation and duration changes in the 1980's and has recovered in the recent decades. This finding implies that it might not necessarily be right to use long data sets for model calibration. Further investigation confirms that the Angstrom model performs the best with higher NSE (nash-sutcliffe efficiency) of 0.914 and lower MAPE (mean absolute percentage error) and RMSE (root mean square error) values of 13.7 w/m 2 and 23.9 w/m 2 respectively, when calibrated with a 10-year data set. In contrast, the model performs worst when it is calibrated with a 40-year data set, with NSE, MAPE and RMSE values of 0.891, 15.1 w/m 2 and 25.3 w/m 2 , respectively

Media interest in aesthetic surgery is substantial and suggestions of demographic changes such as reductions in age or an increase in the number of male patients are common. In spite of this, there is no peer reviewed literature reporting demographics of a contemporary large patient cohort or of the effect of macroeconomic indicators on aesthetic surgery in the UK. In this study, computer records 13006 patients presenting between 1998 and the first quarter of 2003 at a significant aesthetic surgery centre were analysed for procedures undergone, patient age and sex. Male to female ratios for each procedure were calculated and a comparison was made between unit activity and macroeconomic indicators. The results showed that there has been no significant demographic change in the procedures studied with patient age and male to female ratio remaining constant throughout the period studied for each procedure. Comparison with macroeconomic indicators suggested increasing demand for aesthetic surgery in spite of a global recession. In conclusion, media reports of large scale demographic shifts in aesthetic surgery patients are exaggerated. The stability of unit activity in spite of falling national economic indicators suggested that some units in the UK might be relatively immune to economic vagaries. The implications for training are discussed.

Statement about UK referendum on the EU

Dear Colleagues, Many people have expressed their concerns about the consequences of the 23 June vote in the UK for CERN, and for the UK’s relationship with CERN. CERN is an intergovernmental organisation subject to its own treaty. We are not part of the European Union, and several of our Member States, including Switzerland, in which we are headquartered, are not EU Members. Britain’s membership of CERN is not affected by the UK electorate’s vote to leave the European Union. We look forward to continuing the very constructive relationship we have shared with the UK, one of our founding members, long into the future. CERN was founded on the principle of international collaboration, and our success over the years is built on that. We will continue to work proactively to encourage ever-greater international collaboration in particle physics, and to help ensure that the UK continues to play a very active role. UK nationals remain eligible for all categories of employment at CERN, a...

UK nuclear terrorism insurance arrangements: an overview

International Nuclear Information System (INIS)

Tetley, M. G.

2004-01-01

The risk of terrorism in the UK is not new, but since the New York World Trade Centre attacks in 2001, the potential scale of any terrorist attack has required a considerable reassessment. With UK foreign policy closely aligned to that of the USA, the UK security services now consider it is simply a matter of when and no longer if the UK is attacked. For insurers of any type this fact would cause concern; for insurers involved in high profile and potentially catastrophic loss targets such as nuclear power plants, any attack could have a severe impact on solvency and shareholder's funds. This paper's objective is to describe the terrorism insurance arrangements put in place in the U.K. both before and after the September 2001 attacks. These arrangements have been designed both to safeguard insurers' solvency and to ensure that the nuclear industry and general public can continue to be reassured by the availability of insurance should an attack ever occur.(author)

The future of the UK gas network

International Nuclear Information System (INIS)

Dodds, Paul E.; McDowall, Will

2013-01-01

The UK has an extensive natural gas pipeline network supplying 84% of homes. Previous studies of decarbonisation pathways using the UK MARKAL energy system model have concluded that the low-pressure gas networks should be mostly abandoned by 2050, yet most of the iron pipes near buildings are currently being replaced early for safety reasons. Our study suggests that this programme will not lock-in the use of gas in the long-term. We examine potential future uses of the gas network in the UK energy system using an improved version of UK MARKAL that introduces a number of decarbonisation options for the gas network including bio-methane, hydrogen injection to the natural gas and conversion of the network to deliver hydrogen. We conclude that hydrogen conversion is the only gas decarbonisation option that might enable the gas networks to continue supplying energy to most buildings in the long-term, from a cost-optimal perspective. There is an opportunity for the government to adopt a long-term strategy for the gas distribution networks that either curtails the iron mains replacement programme or alters it to prepare the network for hydrogen conversion; both options could substantially reduce the long-term cost of supplying heat to UK buildings. - Highlights: • We examine the long-term future of the UK gas pipe networks using the UK MARKAL model. • The iron mains replacement programme will not lead to gas infrastructure lock-in. • Bio-methane and hydrogen injection have only a small role in our future scenarios. • The most cost-optimal strategy might be to convert the networks to deliver hydrogen. • Adopting a long-term gas strategy could reduce the cost of providing heat in the UK

Total cost estimates for large-scale wind scenarios in UK

International Nuclear Information System (INIS)

Dale, Lewis; Milborrow, David; Slark, Richard; Strbac, Goran

2004-01-01

The recent UK Energy White Paper suggested that the Government should aim to secure 20% of electricity from renewable sources by 2020. A number of estimates of the extra cost of such a commitment have been made, but these have not necessarily included all the relevant cost components. This analysis sets out to identify these and to calculate the extra cost to the electricity consumer, assuming all the renewable electricity is sourced from wind energy. This enables one of the more controversial issues--the implications of wind intermittency--to be addressed. The basis of the assumptions associated with generating costs, extra balancing costs and distribution and transmission system reinforcement costs are all clearly identified and the total costs of a '20% wind' scenario are compared with a scenario where a similar amount of energy is generated by gas-fired plant. This enables the extra costs of the renewables scenario to be determined. The central estimate of the extra costs to electricity consumers is just over 0.3 p/kW h in current prices (around 5% extra on average domestic unit prices). Sensitivity analyses examine the implications of differing assumptions. The extra cost would rise if the capital costs of wind generation fall slower than anticipated, but would fall if gas prices rise more rapidly than has been assumed, or if wind plant are more productive. Even if it is assumed that wind has no capacity displacement value, the added cost to the electricity consumer rises by less than 0.1 p/kW h. It is concluded that there does not appear to be any technical reason why a substantial proportion of the country's electricity requirements could not be delivered by wind

Living in a network of scaling cities and finite resources.

2015-02-01

Many urban phenomena exhibit remarkable regularity in the form of nonlinear scaling behaviors, but their implications on a system of networked cities has never been investigated. Such knowledge is crucial for our ability to harness the complexity of urban processes to further sustainability science. In this paper, we develop a dynamical modeling framework that embeds population-resource dynamics-a generalized Lotka-Volterra system with modifications to incorporate the urban scaling behaviors-in complex networks in which cities may be linked to the resources of other cities and people may migrate in pursuit of higher welfare. We find that isolated cities (i.e., no migration) are susceptible to collapse if they do not have access to adequate resources. Links to other cities may help cities that would otherwise collapse due to insufficient resources. The effects of inter-city links, however, can vary due to the interplay between the nonlinear scaling behaviors and network structure. The long-term population level of a city is, in many settings, largely a function of the city's access to resources over which the city has little or no competition. Nonetheless, careful investigation of dynamics is required to gain mechanistic understanding of a particular city-resource network because cities and resources may collapse and the scaling behaviors may influence the effects of inter-city links, thereby distorting what topological metrics really measure.

Computer modelling of the UK wind energy resource: UK wind speed data package and user manual

Energy Technology Data Exchange (ETDEWEB)

Burch, S F; Ravenscroft, F

1993-12-31

A software package has been developed for IBM-PC or true compatibles. It is designed to provide easy access to the results of a programme of work to estimate the UK wind energy resource. Mean wind speed maps and quantitative resource estimates were obtained using the NOABL mesoscale (1 km resolution) numerical model for the prediction of wind flow over complex terrain. NOABL was used in conjunction with digitised terrain data and wind data from surface meteorological stations for a ten year period (1975-1984) to provide digital UK maps of mean wind speed at 10m, 25m and 45m above ground level. Also included in the derivation of these maps was the use of the Engineering Science Data Unit (ESDU) method to model the effect on wind speed of the abrupt change in surface roughness that occurs at the coast. With the wind speed software package, the user is able to obtain a display of the modelled wind speed at 10m, 25m and 45m above ground level for any location in the UK. The required co-ordinates are simply supplied by the user, and the package displays the selected wind speed. This user manual summarises the methodology used in the generation of these UK maps and shows computer generated plots of the 25m wind speeds in 200 x 200 km regions covering the whole UK. The uncertainties inherent in the derivation of these maps are also described, and notes given on their practical usage. The present study indicated that 23% of the UK land area had speeds over 6 m/s, with many hill sites having 10m speeds over 10 m/s. It is concluded that these `first order` resource estimates represent a substantial improvement over the presently available `zero order` estimates. (18 figures, 3 tables, 6 references). (author)

The UK Smoke Constituents Testing Study. Summary of Results and Comparison with Other Studies

Directory of Open Access Journals (Sweden)

Gregg E

Full Text Available At the request of the UK Department of Health, samples of 25 commercial UK cigarette brands were provided to LGC Ltd a for smoke analysis. The brands reflected a high market share (58% in July 2001 and included a wide range of blend and product styles manufactured and imported into the UK.= 0.76, suggesting a minor role of other design features on constituents yield variability. This was confirmed by the application of multiple regression analysis to the data. A subset of five brands, retested at another laboratory, gave between-laboratory differences in mean constituent yields of as much as 2.5-fold. Consideration of these results, other likely sources of analytical variation in this study and a review of other studies, clearly indicates that any tolerance values to be associated with individual smoke constituent measurements will be greater than those for NFDPM, and in some cases, much greater. Consistent with the reported results from other large studies it is concluded that, under ISO smoking conditions, smoke constituent yields are largely predictable, if NFDPM and CO yields are known, for a standard cigarette. Given these observations and the likely limitations of analytical determination, the need for routine measurement of smoke constituent yields, other than NFDPM, nicotine or CO, on standard cigarettes, is questionable.

In recent years, with a growing interest in big or large datasets, there has been a rise in the application of large graphs and networks to financial big data. Much of this research has focused on the construction and analysis of the network structure of stock markets, based on the relationships between stock prices. Motivated by Boginski et al. (2005), who studied the characteristics of a network structure of the US stock market, we construct network graphs of the UK stock market using same method. We fit four distributions to the degree density of the vertices from these graphs, the Pareto I, Fréchet, lognormal, and generalised Pareto distributions, and assess the goodness of fit. Our results show that the degree density of the complements of the market graphs, constructed using a negative threshold value close to zero, can be fitted well with the Fréchet and lognormal distributions.

Seismic Hazard Management in Mexico City

Science.gov (United States)

Wintergerst, L.

2007-05-01

Mexico City is one of the largest cities in the world. More than 8.5 million residents and 4.5 million floating population are in the city itself, but with the surrounding suburbs the number of people that could be affected by natural and man-made hazards rises to approximately 20 million. The main risk to the city as a whole is a large magnitude earthquake. Since there is reason to prepare for a credible seismic scenario of Mw = 8.2, which would exceed the damages caused during the 1985 earthquake (Mw = 8.1), we founded the Metropolitan Geologic Service (MGS) in 1998. The MGS has developed geologic and seismic hazard maps for the city (http:www.proteccioncivil.df.gob.mx). The maps include three separate risk maps for low height (3 stories), medium height (10 stories) and tall buildings (10 stories). The maps were prepared by using the maximum horizontal accelerations documented during the 1985 earthquake, and wave propagation modeling for buildings of different resonant periods (T = 0.0, 1.0 and 2.0 sec). In all cases, the risk zones were adjusted to include documented damage during the 1957, 1979 and 1985 earthquakes. All three maps show a high risk zone in the north-central portion of the city, elongated in a N-S direction, which corresponds with a narrow graben where the thickness of alluvial sediments is particularly large, and where wave amplification is accentuated. Preparation of these maps, and others used for planning, has been facilitated by the ongoing elaboration of a Dynamic Geographical Information System, which is based on geo-scientific information, includes all types of risks, and incorporates vulnerability models. From the risk management standpoint, we have elaborated the Permanent Contingency Plan for Mexico City, which in its Earthquakes chapter includes plans for coordination and for organizing attention to the population in the event of a seismic disaster. This Permanent Plan follows the philosophy of Descartes' Method, has 11 processes (6

Uncertainties in key low carbon power generation technologies - Implication for UK decarbonisation targets

International Nuclear Information System (INIS)

Kannan, R.

2009-01-01

The UK government's economy-wide 60% carbon dioxide reduction target by 2050 requires a paradigm shift in the whole energy system. Numerous analytical studies have concluded that the power sector is a critical contributor to a low carbon energy system, and electricity generation has dominated the policy discussion on UK decarbonisation scenarios. However, range of technical, social and market challenges, combined with alternate market investment strategies mean that large scale deployment of key classes of low carbon electricity technologies is fraught with uncertainty. The UK MARKAL energy systems model has been used to investigate these long-term uncertainties in key electricity generation options. A range of power sector specific parametric sensitivities have been performed under a 'what-if' framework to provide a systematic exploration of least-cost energy system configurations under a broad, integrated set of input assumptions. In this paper results of six sensitivities, via restricted investments in key low carbon technologies to reflect their technical and political uncertainties, and an alternate investment strategies from perceived risk and other barriers, have been presented.

The taxation of UK oil and gas production. Why the windfalls got away

Energy Technology Data Exchange (ETDEWEB)

Abdo, Hafez [Nottingham Business School, Burton Street, Nottingham NG1 4BU (United Kingdom)

2010-10-15

Starting with evidence that United Kingdom Continental Shelf oil and gas companies have benefitted very disproportionately from the recent period of extraordinarily high oil prices, this paper traces the history of this weakness in the UK's petroleum fiscal regime. Evidence is provided that the progressive relaxations in the UK's petroleum fiscal regime in 1983, 1987-1988 and 1993 were: largely unnecessary to stimulate the development of new, smaller, 'marginal' fields; misguided in their assumption that such fields were more costly to develop than earlier counterparts or larger contemporary fields; and impotent compared with the effects of oil price movements. The paper concludes with a conceptualisation which illuminates why these failures of policy were not just random: they emerged from the UK's 'non-proprietorial' stance with respect to the country's oil and gas resources, a stance which assumes responsibility for oil company profitability and vainly tries to counter market forces at the expense of government revenues.

The Copper Balance of Cities: Exploratory Insights into a European and an Asian City.

Material management faces a dual challenge: on the one hand satisfying large and increasing demands for goods and on the other hand accommodating wastes and emissions in sinks. Hence, the characterization of material flows and stocks is relevant for both improving resource efficiency and environmental protection. This article focuses on the urban scale, a dimension rarely investigated in past metal flow studies. We compare the copper (Cu) metabolism of two cities in different economic states, namely, Vienna (Europe) and Taipei (Asia). Substance flow analysis is used to calculate urban Cu balances in a comprehensive and transparent form. The main difference between Cu in the two cities appears to be the stock: Vienna seems close to saturation with 180 kilograms per capita (kg/cap) and a growth rate of 2% per year. In contrast, the Taipei stock of 30 kg/cap grows rapidly by 26% per year. Even though most Cu is recycled in both cities, bottom ash from municipal solid waste incineration represents an unused Cu potential accounting for 1% to 5% of annual demand. Nonpoint emissions are predominant; up to 50% of the loadings into the sewer system are from nonpoint sources. The results of this research are instrumental for the design of the Cu metabolism in each city. The outcomes serve as a base for identification and recovery of recyclables as well as for directing nonrecyclables to appropriate sinks, avoiding sensitive environmental pathways. The methodology applied is well suited for city benchmarking if sufficient data are available.

Cities and Sea Level Rise: A Roadmap for Flood Hazard Adaptation

Science.gov (United States)

Horn, D. P.; Cousins, A.

2015-12-01

Coastal cities will face a range of increasingly severe challenges as sea level rises, and adaptation to future flood risk will require more than structural defences. Many cities will not be able to rely solely on engineering structures for protection and will need to develop a suite of policy responses to increase their resilience to impacts of rising sea level. Local governments generally maintain day-to-day responsibility and control over the use of the vast majority of property at risk of flooding, and the tools to promote flood risk adaptation are already within the capacity of most cities. Policy tools available to address other land-use problems can be refashioned and used to adapt to sea level rise. This study reviews approaches for urban adaptation through case studies of cities which have developed flood adaptation strategies that combine structural defences with innovative approaches to living with flood risk. The aim of the overall project is to produce a 'roadmap' to guide practitioners through the process of analysing coastal flood risk in urban areas. Technical knowledge of flood risk reduction measures is complemented with a consideration of the essential impact that local policy has on the treatment of coastal flooding and the constraints and opportunities that result from the specific country or locality characteristics in relation to economic, political, social and environmental priorities, which are likely to dictate the approach to coastal flooding and the actions proposed. Detailed analyses of the adaptation strategies used by Rotterdam (Netherlands), Bristol (UK), and Norfolk (Virginia) are used to draw out a range of good practice elements that promote effective adaptation to sea level rise. These can be grouped into risk reduction, governance issues, and insurance, and can be used to provide examples of how other cities could adopt and implement flood adaptation strategies from a relatively limited starting position. Most cities will

Helfter, Carole; Nemitz, Eiko; Barlow, Janet F.; Wood, Curtis R.

London, with a population of 8.2 million, is the largest city in Europe. It is heavily built-up (typically 8% vegetation cover within the central boroughs) and boasts some of the busiest arteries in Europe despite efforts to reduce traffic in the city centre with the introduction of a congestion charging scheme in 2007. We report on two substantial pollution monitoring efforts in the heart of London between October 2006 and present. Fluxes of carbon dioxide (CO2) and water (H2O) were measured continuously by eddy-covariance in central London from October 2006 until May 2008 from a 190 m telecommunication tower (BT tower; 51° 31' 17.4'' N 0° 8' 20.04'' W). The eddy-covariance system consisted of a Gill R3-50 ultrasonic anemometer operated at 20 Hz and a LI-COR 6262 infrared gas analyser. Air was sampled 0.3 m below the sensor head of the ultrasonic anemometer - which was itself mounted on a 3 m mast to the top of a 15 m lattice tower situated on the roof of the tower (instrument head at 190 m above street level) - and pulled down 45 m of 12.7 mm OD Teflon tubing. In addition, meteorological variables (temperature, relative humidity, pressure, precipitation, wind speed and direction) were also measured with a multi-sensor (Weather Transmitter WXT510, Vaisala). Eddy-covariance measurements at the BT tower location were reinstated in July 2011 and include methane (CH4), CO2 and H2O concentrations measured by a Picarro fast methane analyser (G2301-f). CO2 emissions were found to be mainly controlled by fossil fuel combustion (e.g. traffic, commercial and domestic heating). Diurnal averages of CO2 fluxes were found to be highly correlated to traffic. However changes in heating-related natural gas consumption and, to a lesser extent, photosynthetic activity in two large city centre green spaces (Hyde Park and Regent's Park) explained the seasonal variability. Annual estimates of net exchange of CO2 obtained by eddy-covariance agreed well with up-scaled data from the UK

This report summarises the work undertaken under the EU-FP7 TRANSFORM project for Work Package 1 (part 1): Becoming a Smart Energy City, state of the Art and Ambition. Part 1 starts with a clear outline of each of the participating cities. The work describes the context in terms of climate, energy assets, ambitions, targets and main possibilities in terms of energy efficiency, flows and energy production. After this first step, the work focuses on the description of what a smart energy city is (this report), what the main Key Performance Indicators (KPIs) are that should be met and how this relates to where the current cities and the living labs are. It describes at the same time the current status of city planning, energy planning tools, and existing energy data. The outline should also include information on energy production, energy flows and energy efficiency, where possible. The work will draw largely on existing Strategic Energy Action Plans, Climate Action Plans and planning documents. This report establishes a definition of smart cities, develops Key Elements, Key Performance Indicators and reports on the state of the art regarding the KPIs for the 6 Transform cities. As specified in the Transform proposal, the objective of the evaluation is to identify previous and existing initiatives as a sort of stocktaking on the way to establishing a smart city transformation pathway for each of the participating cities in the Transform project. The definition of a smart energy city and the key performance indicators will be used throughout Transform the guide the work. (Author)

The current study aimed to examine the effects of daily change of the Shenzhen Stock Exchange Index on cardiovascular mortality in Guangzhou and Taishan, China. Daily mortality and stock performance data during 2006-2010 were collected to construct the time series for the two cities. A distributed lag non-linear model was utilized to examine the effect of daily stock index changes on cardiovascular mortality after controlling for potential confounding factors. We observed a delayed non-linear effect of the stock index change on cardiovascular mortality: both rising and declining of the stock index were associated with increased cardiovascular deaths. In Guangzhou, the 15-25 lag days cumulative relative risk of an 800 index drop was 2.08 (95% CI: 1.38-3.14), and 2.38 (95% CI: 1.31-4.31) for an 800 stock index increase on the cardiovascular mortality, respectively. In Taishan, the cumulative relative risk over 15-25 days lag was 1.65 (95% CI: 1.13-2.42) for an 800 index drop and 2.08 (95% CI: 1.26-3.42) for an 800 index rising, respectively. Large ups and downs in daily stock index might be important predictor of cardiovascular mortality.

In Europe, several local areas have a number of years of experience with implementing local energy and greenhouse gas management policies, addressing national and international climate change targets. For example, in the city of Leicester in the UK, local strategies and measures have been implemented over several years to improve the energy efficiency of the Council's own operations and to manage city-wide energy consumption and greenhouse gas emissions. Recently, Leicester has participated in a European Commission funded project, which explores the potential for European local authorities and agencies to use their experience to work with a local area in a developing country where energy demand has been increasing rapidly, addressing climate change and sustainable development issues. The project has aimed to provide support at the local level with developing a framework to minimise energy-related contributions to climate change and air pollution, while giving quality of life benefits. It has used a partnership approach between Leicester, Vila Nova de Gaia municipality in Portugal, and a city in the Gujarat, India. The local level's role in each country in local energy management has been investigated. This has included a baseline assessment of local energy use, renewable energy and climate change issues in each partner city. The most locally relevant energy technologies have been selected and their implementation discussed in the local workshops involving a range of organisations and individuals, with actions being identified to improve the local management of energy, such as raising awareness and ensuring easy access to information

Stedman, John R; Grice, Susannah; Kent, Andrew; Cooke, Sally

2009-01-01

GIS-based models have been developed to map ambient PM 10 and PM 25 mass concentrations across the UK. The resulting maps are used for the assessments of air quality required by the EU ambient air quality directives, health impact assessment and the development of UK air quality policy. Maps are presented for 2006 along with projections to 2020. The largest single contribution to the UK population-weighted mean annual mean background concentrations of PM 10 in 2006 is estimated to be from secondary PM (43%), followed by the contribution from primary PM (24%). Concentrations are predicted to decline by 15% for PM 10 and 13% for PM 25 over the period from 2006 to 2020. The extent of exceedence of the 24-hour limit value is predicted to decline from 1.9% to 0.1% of urban major roads over the same period. The potential health benefits of reductions in ambient PM are large. A reduction in concentration of 0.93 μg m -3 as a result of a possible package of measures has been estimated within the UK Air Quality Strategy to result in a reduction in life years lost of approximately 2 - 4 million over a period of 100 years.

Strategy for energy policy in the UK

Stone, T.

2012-01-01

UK Energy Policy is leading the world in showing how governments can effectively respond to the now widely accepted challenges of security of supply, low-carbon generation and pragmatic implementation. Confidence in the UK as place to invest in new nuclear is very high-there are already 3 developers who have between them already invested over 1 billion, 5 sites are planned to be developed and between 10 and 12 new reactors are planned to be built. To be clear, this is by far the largest commitment to new nuclear in the Western World and swamps in other countries. This achievement is a combination of vision, continuity, political consensus and a group of ministers and officials who are clear in the goals for the long-term sustain ability of an energy policy that will dramatically affect the lives of many generations to come. Recognising the multi-generational obligations and consequences of government policy's key to ensuring that this investment continues, together with the maintenance of the trust that investors have developed in the management of energy policy by the UK government. There is no doubt in the commitment of the UK government to delivering the safe, secure and low-carbon energy future of the UK. The opportunities for businesses and high-quality job creation are undoubted-all that now has to happen is for developers, reactor vendors, construction companies and communities to show how they can together deliver the cheapest form of low-carbon base load to time and to cost and to the benefit of local communities and the UK economy. the world is watching for the UK to show how it can be done.

Development and application of a mechanistic model to estimate emission of nitrous oxide from UK agriculture

2002-01-01

A mechanistic model of N 2 O emission from agricultural soil (DeNitrification-DeComposition - DNDC) was modified for application to the UK, and was used as the basis of an inventory of N 2 O emission from UK agriculture in 1990. UK-specific input data were added to DNDC's database and the ability to simulate daily C and N inputs from grazing animals and applied animal waste was added to the model. The UK version of the model, UK-DNDC, simulated emissions from 18 different crop types on the 3 areally dominant soils in each county. Validation of the model at the field scale showed that predictions matched observations well. Emission factors for the inventory were calculated from estimates of N 2 O emission from UK-DNDC, in order to maintain direct comparability with the IPCC approach. These, along with activity data, were included in a transparent spreadsheet format. Using UK-DNDC, the estimate of N 2 O-N emission from UK current agricultural practice in 1990 was 50.9Gg. This total comprised 31.7Gg from the soil sector, 5.9Gg from animals and 13.2Gg from the indirect sector. The range of this estimate (using the range of soil organic C for each soil used) was 30.5-62.5Gg N. Estimates of emissions in each sector were compared to those calculated using the IPCC default methodology. Emissions from the soil and indirect sectors were smaller with the UK-DNDC approach than with the IPCC methodology, while emissions from the animal sector were larger. The model runs suggested a relatively large emission from agricultural land that was not attributable to current agricultural practices (33.8Gg in total, 27.4Gg from the soil sector). This 'background' component is partly the result of historical agricultural land use. It is not normally included in inventories of emission, but would increase the total emission of N 2 O-N from agricultural land in 1990 to 78.3Gg. (Author)

The role of one large greenspace in mitigating London's nocturnal urban heat island.

Science.gov (United States)

Doick, Kieron J; Peace, Andrew; Hutchings, Tony R

2014-09-15

The term urban heat island (UHI) describes a phenomenon where cities are on average warmer than the surrounding rural area. Trees and greenspaces are recognised for their strong potential to regulate urban air temperatures and combat the UHI. Empirical data is required in the UK to inform predictions on cooling by urban greenspaces and guide planning to maximise cooling of urban populations. We describe a 5-month study to measure the temperature profile of one of central London's large greenspaces and also in an adjacent street to determine the extent to which the greenspace reduced night-time UHI intensity. Statistical modelling displayed an exponential decay in the extent of cooling with increased distance from the greenspace. The extent of cooling ranged from an estimated 20 m on some nights to 440 m on other nights. The mean temperature reduction over these distances was 1.1 °C in the summer months, with a maximum of 4 °C cooling observed on some nights. Results suggest that calculation of London's UHI using Met Stations close to urban greenspace can underestimate 'urban' heat island intensity due to the cooling effect of the greenspace and values could be in the region of 45% higher. Our results lend support to claims that urban greenspace is an important component of UHI mitigation strategies. Lack of certainty over the variables that govern the extent of the greenspace cooling influence indicates that the multifaceted roles of trees and greenspaces in the UK's urban environment merit further consideration.

Empirical regression models for next-day forecasting of PM2.5 and O3 air pollution concentrations have been developed and evaluated for three large Chinese cities, Beijing, Nanjing and Guangzhou. The forecast models are empirical nonlinear regression models designed for use in an automated data retrieval and forecasting platform. The PM2.5 model includes an upwind air quality variable, PM24, to account for regional transport of PM2.5, and a persistence variable (previous day PM2.5 concentration). The models were evaluated in the hindcast mode with a two-year air quality and meteorological data set using a leave-one-month-out cross validation method, and in the forecast mode with a one-year air quality and forecasted weather dataset that included forecasted air trajectories. The PM2.5 models performed well in the hindcast mode, with coefficient of determination (R2) values of 0.54, 0.65 and 0.64, and normalized mean error (NME) values of 0.40, 0.26 and 0.23 respectively, for the three cities. The O3 models also performed well in the hindcast mode, with R2 values of 0.75, 0.55 and 0.73, and NME values of 0.29, 0.26 and 0.24 in the three cities. The O3 models performed better in summertime than in winter in Beijing and Guangzhou, and captured the O3 variations well all the year round in Nanjing. The overall forecast performance of the PM2.5 and O3 models during the test year varied from fair to good, depending on location. The forecasts were somewhat degraded compared with hindcasts from the same year, depending on the accuracy of the forecasted meteorological input data. For the O3 models, the model forecast accuracy was strongly dependent on the maximum temperature forecasts. For the critical forecasts, involving air quality standard exceedences, the PM2.5 model forecasts were fair to good, and the O3 model forecasts were poor to fair.

Many sources suggest that cities account for a large proportion of global anthropogenic greenhouse gas emissions. Therefore, in search for the best ways to reduce total anthropogenic greenhouse gas emissions, a focus on the city emission is crucial. In this study, we collected CO2 emissions data in 30 cities during 1990-2015 and evaluated the degree of variance between data sources. The CO2 emissions data were obtained from academic papers, municipal reports, and high-resolution emissions maps (CIDIACv2016, EDGARv4.2, ODIACv2016, and FFDASv2.0). To extract urban CO2 emissions from the high-resolution emissions maps, urban fraction ranging from 0 to 1 was calculated for each 1×1 degree grid cell using the global land cover data (SYNMAP). Total CO2 emissions from the grid cells in which urban fraction occupies greater than or equal to 0.9 were regarded as urban CO2 emissions. The estimated CO2 emissions varied greatly depending on the information sources, even in the same year. There was a large difference between CO2 emissions collected from academic papers, municipal reports, and those extracted from high-resolution emissions maps. One reason is that they use different city boundaries. That is, the city proper (i.e. the political city boundary) is often defined as the city boundary in academic papers and municipal reports, whereas the urban area is used in the high-resolution emissions maps. Furthermore, there was a large variation in CO2 emissions collected from academic papers and municipal reports. These differences may be due to the difference in the assumptions such as allocation ratio of CO2 emissions to producers and consumers. In general, the consumption-based assignment of emissions gives higher estimates of urban CO2 emission in comparison with production-based assignment. Furthermore, there was also a large variation in CO2 emissions extracted from high-resolution emissions maps. This difference would be attributable to differences in information used

Diffuse large B-cell lymphoma (DLBCL) is the commonest non-Hodgkin lymphoma. Previous studies examining the cost of treating DLBCL have generally focused on a specific first-line therapy alone; meaning that their findings can neither be extrapolated to the general patient population nor to other points along the treatment pathway. Based on empirical data from a representative population-based patient cohort, the objective of this study was to develop a simulation model that could predict costs and life expectancy of treating DLBCL. All patients newly diagnosed with DLBCL in the UK's population-based Haematological Malignancy Research Network ( www.hmrn.org ) in 2007 were followed until 2013 (n = 271). Mapped treatment pathways, alongside cost information derived from the National Tariff 2013/14, were incorporated into a patient-level simulation model in order to reflect the heterogeneities of patient characteristics and treatment options. The NHS and social services perspective was adopted, and all outcomes were discounted at 3.5 % per annum. Overall, the expected total medical costs were £22,122 for those treated with curative intent, and £2930 for those managed palliatively. For curative chemotherapy, the predicted medical costs were £14,966, £23,449 and £7376 for first-, second- and third-line treatments, respectively. The estimated annual cost for treating DLBCL across the UK was around £88-92 million. This is the first cost modelling study using empirical data to provide 'real world' evidence throughout the DLBCL treatment pathway. Future application of the model could include evaluation of new technologies/treatments to support healthcare decision makers, especially in the era of personalised medicine.

Mixing ratios and eddy covariance flux measurements of volatile organic compounds from an urban canopy (Manchester, UK

2009-03-01

Full Text Available Mixing ratios and fluxes of six selected volatile organic compounds (VOCs were measured above the city of Manchester (UK during the summer of 2006. A proton transfer reaction-mass spectrometer was used for the measurement of mixing ratios, and fluxes were calculated from these using both the disjunct and the virtual disjunct eddy covariance techniques. The two flux systems, which operated in alternate half hours, showed good agreement, with R² values ranging between 0.74 and 0.9 for the individual analytes. On average, fluxes measured in the disjunct mode were approximately 20% lower than those measured in the virtual mode. This difference is due to both the dampening of the VOC signal by the disjunct flux sampler and carry over from one sample to the next. Correcting for these effects reduced the difference to less than 7%. Observed fluxes are thought to be largely controlled by anthropogenic sources, with vehicle emissions the major contributor. However, both evaporative and biogenic emissions may account for some of the VOCs present. Concentrations and fluxes of the oxygenated compounds were highest on average, ranging between 0.15 to 1 mg m⁻² h⁻¹; the fluxes of aromatic compounds were lower, between 0.12 to 0.28 mg m⁻² h⁻¹. The observed fluxes were up-scaled to give city wide emission estimates for each compound and the results compared to estimates made by the National Atmospheric Emission Inventory (NAEI for the same flux footprint. Fluxes of toluene and benzene compared most closely differing by approximately 50%, while in contrast the oxygenated fluxes were found to be between 3.6–6.3 times larger than the annual average predicted by the NAEI.

Rapid worldwide urbanization is at once the main cause and, potentially, the main solution to global sustainable development challenges. The growth of cities is typically associated with increases in socioeconomic productivity, but it also creates strong inequalities. Despite a growing body of evidence characterizing these heterogeneities in developed urban areas, not much is known systematically about their most extreme forms in developing cities and their consequences for sustainability. Here, we characterize the general patterns of income and access to services in a large number of developing cities, with an emphasis on an extensive, high-resolution analysis of the urban areas of Brazil and South Africa. We use detailed census data to construct sustainable development indices in hundreds of thousands of neighborhoods and show that their statistics are scale-dependent and point to the critical role of large cities in creating higher average incomes and greater access to services within their national context. We then quantify the general statistical trajectory toward universal basic service provision at different scales to show that it is characterized by varying levels of inequality, with initial increases in access being typically accompanied by growing disparities over characteristic spatial scales. These results demonstrate how extensions of these methods to other goals and data can be used over time and space to produce a simple but general quantitative assessment of progress toward internationally agreed sustainable development goals.

2011-01-01

Full Text Available Xenotropic murine leukaemia virus-related virus (XMRV is a recently described retrovirus which has been claimed to infect humans and cause associated pathology. Initially identified in the US in patients with prostate cancer and subsequently in patients with chronic fatigue syndrome, doubt now exists that XMRV is a human pathogen. We studied the prevalence of genetic sequences of XMRV and related MuLV sequences in human prostate cancer, from B cell lymphoma patients and from UK blood donors. Nucleic acid was extracted from fresh prostate tissue biopsies, formalin-fixed paraffin-embedded (FFPE prostate tissue and FFPE B-cell lymphoma. The presence of XMRV-specific LTR or MuLV generic gag-like sequences was investigated by nested PCR. To control for mouse DNA contamination, a PCR that detected intracisternal A-type particle (IAP sequences was included. In addition, DNA and RNA were extracted from whole blood taken from UK blood donors and screened for XMRV sequences by real-time PCR. XMRV or MuLV-like sequences were not amplified from tissue samples. Occasionally MuLV gag and XMRV-LTR sequences were amplified from Indian prostate cancer samples, but were always detected in conjunction with contaminating murine genomic DNA. We found no evidence of XMRV or MuLV infection in the UK blood donors.

Eighty-five percent of United States citizens live in urban areas. However, research surrounding the resilience and sustainability of complex urban systems focuses largely on coastal megacities (>1 million people). Midsize cities differ from their larger counterparts due to tight urban-rural feedbacks with their immediate natural environments that result from heavy reliance and close management of local ecosystem services. They also may be less path-dependent than larger cities due to shorter average connection length among system components, contributing to higher responsiveness among social, infrastructural, and ecological feedbacks. These distinct midsize city features call for a framework that organizes information and concepts concerning the sustainability of midsize cities specifically. We argue that an integrative approach is necessary to capture properties emergent from the complex interactions of the social, infrastructural, and ecological subsystems that comprise a city system. We suggest approaches to estimate the relative resilience of midsize cities, and include an example assessment to illustrate one such estimation approach. Resilience assessments of a midsize city can be used to examine why some cities end up on sustainable paths while others diverge to unsustainable paths, and which feedbacks may be partially responsible. They also provide insight into how city planners and decision makers can use information about the resilience of midsize cities undergoing growth or shrinkage relative to their larger and smaller counterparts, to transform them into long-term, sustainable social-ecological systems.

Tax rates on business income in many countries increased enormously during World War I and stayed at a much higher level than before the war. Particularly, the UK multinationals with subsidiaries based elsewhere other than the Empire suffered from the situation because the UK did not provide a foreign tax relief until 1945, when a tax treaty with US was signed. The aim of this paper is to clarify the historical premises of establishment of the tax treaty in 1945. The major premise of this pap...

Efficient Scavenging of Solar and Wind Energies in a Smart City.

To realize the sustainable energy supply in a smart city, it is essential to maximize energy scavenging from the city environments for achieving the self-powered functions of some intelligent devices and sensors. Although the solar energy can be well harvested by using existing technologies, the large amounts of wasted wind energy in the city cannot be effectively utilized since conventional wind turbine generators can only be installed in remote areas due to their large volumes and safety issues. Here, we rationally design a hybridized nanogenerator, including a solar cell (SC) and a triboelectric nanogenerator (TENG), that can individually/simultaneously scavenge solar and wind energies, which can be extensively installed on the roofs of the city buildings. Under the same device area of about 120 mm × 22 mm, the SC can deliver a largest output power of about 8 mW, while the output power of the TENG can be up to 26 mW. Impedance matching between the SC and TENG has been achieved by using a transformer to decrease the impedance of the TENG. The hybridized nanogenerator has a larger output current and a better charging performance than that of the individual SC or TENG. This research presents a feasible approach to maximize solar and wind energies scavenging from the city environments with the aim to realize some self-powered functions in smart city.

Distributed Leadership in a Low-Carbon City Agenda

Directory of Open Access Journals (Sweden)

Azalia Mohamed

2016-07-01

Full Text Available This paper uses Spillane’s (2001 theory and Gronn’s (2000 concerted efforts approach to examine distributed leadership in a low-carbon city agenda. The main purpose of the paper is to find empirical evidence of a relationship between distributed leadership and the achievement of the agenda. Eight constructs emerged that informed our understanding of distributed leadership dimensions within the low-carbon city framework: vision, organizational framework, organizational culture, consensus, instructional programs, expertise, team leader leadership, and team member leadership. The evidence shows that there is a positive relationship between distributed leadership and the outcome of the low-carbon city agenda, and that a dispersed pattern in distributing leadership is required to enhance community engagement. The findings also suggest that an organizational culture that facilitates multiple sources of leadership may largely contribute to the effectiveness of distributed leadership practices in realizing the low-carbon city agenda.

Operational radiation protection in UK mining

International Nuclear Information System (INIS)

O'Riordan, M.C.

1977-01-01

The radiological conditions of the mining industry (coal-national, coal-private, non-coal) in the UK are described. From the point of view of radiological protection, non-coal miners have the highest occupational exposure of any group in the UK in relation to a recommended limit. From the point of view of general health and safety in non-coal mining, however, the situation does not look no serious. This is illustrated as follows. The US epidemiological study of uranium miners yields, on extrapolation, a risk estimate of some 0.3 deaths annually from lung cancer per 1000 miners exposed to 100 WLM. On the other hand, accident statistics for non-coal mines in the UK yield an estimate of two deaths annually per 1000 miners. Further perspective is given to the problem by the incidence of lung cancer among adult males within the UK, that is, 1.5 cases annually per 1000 persons. Narrow concern for the radiological safety of miners must therefore be tempered with broader concern for the other hazards they face

Influence of exposure differences on city-to-city heterogeneity ...

Science.gov (United States)

Multi-city population-based epidemiological studies have observed heterogeneity between city-specific fine particulate matter (PM2.5)-mortality effect estimates. These studies typically use ambient monitoring data as a surrogate for exposure leading to potential exposure misclassification. The level of exposure misclassification can differ by city affecting the observed health effect estimate. The objective of this analysis is to evaluate whether previously developed residential infiltration-based city clusters can explain city-to-city heterogeneity in PM2.5 mortality risk estimates. In a prior paper 94 cities were clustered based on residential infiltration factors (e.g. home age/size, prevalence of air conditioning (AC)), resulting in 5 clusters. For this analysis, the association between PM2.5 and all-cause mortality was first determined in 77 cities across the United States for 2001–2005. Next, a second stage analysis was conducted evaluating the influence of cluster assignment on heterogeneity in the risk estimates. Associations between a 2-day (lag 0–1 days) moving average of PM2.5 concentrations and non-accidental mortality were determined for each city. Estimated effects ranged from −3.2 to 5.1% with a pooled estimate of 0.33% (95% CI: 0.13, 0.53) increase in mortality per 10 μg/m3 increase in PM2.5. The second stage analysis determined that cluster assignment was marginally significant in explaining the city-to-city heterogeneity. The health effe

Radiological protection and radioactive waste management aspects of the decommissioning of redundant nuclear facilities at the Rosyth Dockyard, UK

2008-01-01

The Rosyth Dockyard is located near the city of Edinburgh in Scotland. The dockyard's nuclear activities centred around the refuelling and refitting of submarines, as well as some submarine decommissioning. In 1993, submarine refitting work was transferred to Devonport in Southern England. This meant that there were a number of facilities at the Rosyth Dockyard that were now redundant. In accordance with UK government policy a programme of works was instigated to allow for the decommissioning of these nuclear liabilities. This paper provides a brief overview of work activities performed to allow physical decommissioning to take place. Topics covered include radiological characterisation activities, development of monitoring protocols for decommissioning, obtaining relevant environmental authorisations, developing a decommissioning safety case, gaining the UK's Nuclear Installations Inspectorate approval to proceed with decommissioning and an overview of some of the post operative clean out (POCO) activities performed. Edmund Nuttall Ltd were contracted to perform the physical decommissioning of the redundant nuclear facilities, that have been subject to POCO, and this work commenced in February 2006. As part of this contract they were to provide a radiological protection infrastructure including dosimetry and health physics monitoring. This paper discusses the radiological protection infrastructure established by the decommissioning contractor, the radiological protection aspects of the decommissioning work, some of the tools and techniques utilised to date during the nuclear decommissioning, and the radioactive waste management processes established for the project. All activities are referenced to relevant aspects of UK nuclear industry best practice and to the Scottish, UK and European regulatory framework. The progress to date is discussed and lessons that have been learnt are highlighted. (author)

Full Text Available The author traces the history of formation of the Indian diaspora in the UK, evaluates the key trends that characterize the current state of diaspora. The article highlights the level of involvement and participation of diaspora in the evolution of the bilateral relations, as well as the influence of diaspora over home and foreign policy in the UK and India. The diaspora today is not just a unique vibrant connection between the two countries, it has also become a factor of influence over domestic, social and economic affairs in both the UK and India. There is a growing number of Indians among British statesmen and politicians. Indians occupy significant posts in various sectors in Britain, including business and finance. This contributes to strengthening of economic ties between the two countries, particularly important considering Britain’s forthcoming exit from the EU. As to internal political matters, though potential issues exist (those include, for instance, the possible transfer from India into Britain of problematic inter-caste relations, India’s criticism over unbalanced approach to teaching colonial history in British schools, the Indian diaspora due to its’ inherent tolerance and moderation generally plays a stabilizing role in the UK, especially on the background of radicalization of other ethnic communities. For the new India the diaspora today is not just an important source of financing, competences and know-how, it is also a significant lobbying and soft-power instrument. This article is part of a broader research, related to the contemporary relations between the United Kingdom and India. Indian diaspora in the UK is an integral part of the unique centuries-long history that connects the two countries. It is poised to remain a strong factor contributing to interdependence and cooperation between Britain and India in the XXI century.

The Earth at a glance 2010: cities, changing trajectory

2010-01-01

The 2010 issue of 'the Earth at a glance' yearly publication is devoted to cities, areas and actors at the forefront of sustainable development. Beyond the status of stakes and obstacles to overcome, the ambition is to identify the dynamics carrying an indispensable trajectory change. More than half of the worldwide population lives in urban areas. Cities generate the most part of the prosperity and knowledge but are also the places where the most fragile populations concentrate and very often in precarious conditions. They are also at the origin of a large part of environment degradations. And yet, it is in the cities that the political, social and environmental questions of the 21. century are debated. In this framework, the cities of emerging countries may open the ways towards a new urbanism by developing new standards.

Urban areas are usually warmer than their surrounding natural areas, an effect known as the urban heat island effect. As such, they are particularly vulnerable to global warming and associated increases in extreme temperatures. Yet ensemble climate-model projections are generally performed on a scale that is too coarse to represent the evolution of temperatures in cities. Here, for the first time, we combine unprecedented long-term (35 years) urban climate model integrations at the convection-permitting scale (2.8 km resolution) with information from an ensemble of general circulation models to assess temperature-based heat stress for Belgium, a densely populated midlatitude maritime region. We discover that the heat stress increase toward the mid-21st century is twice as large in cities compared to their surrounding rural areas. The exacerbation is driven by the urban heat island itself, its concurrence with heat waves, and urban expansion. Cities experience a heat stress multiplication by a factor 1.4 and 15 depending on the scenario. Remarkably, the future heat stress surpasses everywhere the urban hot spots of today. Our results demonstrate the need to combine information from climate models, acting on different scales, for climate change risk assessment in heterogeneous regions. Moreover, these results highlight the necessity for adaptation to increasing heat stress, especially in urban areas.

The concept of a livable smart city presented in this book highlights the relevance of the functionality and integrated resilience of viable cities of the future. It critically examines the progressive digitalization that is taking place and identifies the revolutionized energy sector as the basis of urban life. The concept is based on people and their natural environment, resulting in a broader definition of sustainability and an expanded product theory. Smart City 2.0 offers its residents many opportunities and is an attractive future market for innovative products and services. However, it presents numerous challenges for stakeholders and product developers.

Spatially Explicit Analysis of Water Footprints in the UK

Directory of Open Access Journals (Sweden)

John Barrett

2010-12-01

Full Text Available The Water Footprint, as an indicator of water consumption has become increasingly popular for analyzing environmental issues associated with the use of water resources in the global supply chain of consumer goods. This is particularly relevant for countries like the UK, which increasingly rely on products produced elsewhere in the world and thus impose pressures on foreign water resources. Existing studies calculating water footprints are mostly based on process analysis, and results are mainly available at the national level. The current paper assesses the domestic and foreign water requirements for UK final consumption by applying an environmentally extended multi-regional input-output model in combination with geo-demographic consumer segmentation data. This approach allows us to calculate water footprints (both direct and indirect for different products as well as different geographies within the UK. We distinguished between production and consumption footprints where the former is the total water consumed from the UK domestic water resources by the production activities in the UK and the latter is the total water consumed from both domestic and global water resources to satisfy the UK domestic final consumption. The results show that the production water footprint is 439 m3/cap/year, 85% of which is for the final consumption in the UK itself. The average consumption water footprint of the UK is more than three times bigger than the UK production water footprint in 2006. About half of the UK consumption water footprints were associated with imports from Non-OECD countries (many of which are water-scarce, while around 19% were from EU-OECD countries, and only 3% from Non-EU-OECD countries. We find that the water footprint differs considerably across sub-national geographies in the UK, and the differences are as big as 273 m3/cap/year for the internal water footprint and 802 m3/cap/year for the external water footprint. Our results suggest

2014-01-01

Material management faces a dual challenge: on the one hand satisfying large and increasing demands for goods and on the other hand accommodating wastes and emissions in sinks. Hence, the characterization of material flows and stocks is relevant for both improving resource efficiency and environmental protection. This article focuses on the urban scale, a dimension rarely investigated in past metal flow studies. We compare the copper (Cu) metabolism of two cities in different economic states, namely, Vienna (Europe) and Taipei (Asia). Substance flow analysis is used to calculate urban Cu balances in a comprehensive and transparent form. The main difference between Cu in the two cities appears to be the stock: Vienna seems close to saturation with 180 kilograms per capita (kg/cap) and a growth rate of 2% per year. In contrast, the Taipei stock of 30 kg/cap grows rapidly by 26% per year. Even though most Cu is recycled in both cities, bottom ash from municipal solid waste incineration represents an unused Cu potential accounting for 1% to 5% of annual demand. Nonpoint emissions are predominant; up to 50% of the loadings into the sewer system are from nonpoint sources. The results of this research are instrumental for the design of the Cu metabolism in each city. The outcomes serve as a base for identification and recovery of recyclables as well as for directing nonrecyclables to appropriate sinks, avoiding sensitive environmental pathways. The methodology applied is well suited for city benchmarking if sufficient data are available. PMID:25866460

Characterisation plays a very important role in the nuclear industry supporting: the development and implementation of decommissioning strategies/plans (and the optimisation of associated costs through reduction in technical risks); regulatory compliance demonstration; waste prevention/minimisation; evaluation and optimisation of worker radiation doses; and maintaining public confidence. Recognising these important drivers, the UK regulators are working with the UK Nuclear Decommissioning Authority (NDA) to undertake a review of characterisation practice in the UK nuclear (decommissioning) industry. The objective of the characterisation review is to understand the current characterisation challenges and to determine strategic and tactical opportunities (including sharing of standards and guidance, capabilities, learning from experience, good practice, research and development, training, quality assurance) to optimise characterisation practice. The work is being undertaken through review of nuclear operator's characterisation practice, with input from the NDA, the UK regulators, nuclear operators and representatives from the supply chain, and through consideration of good practice case studies. To support this, a catalogue of relevant national/international guidance documents is also be compiled. Finally a workshop with representatives from all parties has taken place to consider the findings and establish a common understanding of challenges and opportunities and to start to consider how they can be addressed. The review is establishing a collective (UK regulator's, NDA; nuclear operator's and supply chain) understanding of opportunities to improve characterisation practice in the UK. The characterisation review process is described and early results are presented and discussed. Subsequent work in 2016 will be required to prioritise the opportunities and to build a consensus to facilitate development and implementation of an improvement plan. The aim

With a changing climate and increased urbanisation, the occurrence and the impact of flooding is expected to increase significantly. Floods can bring pathogens into homes and cause lingering damp and microbial growth in buildings, with the level of growth and persistence dependent on the volume and chemical and biological content of the flood water, the properties of the contaminating microbes, and the surrounding environmental conditions, including the restoration time and methods, the heat and moisture transport properties of the envelope design, and the ability of the construction material to sustain the microbial growth. The public health risk will depend on the interaction of these complex processes and the vulnerability and susceptibility of occupants in the affected areas. After the 2007 floods in the UK, the Pitt review noted that there is lack of relevant scientific evidence and consistency with regard to the management and treatment of flooded homes, which not only put the local population at risk but also caused unnecessary delays in the restoration effort. Understanding the drying behaviour of flooded buildings in the UK building stock under different scenarios, and the ability of microbial contaminants to grow, persist, and produce toxins within these buildings can help inform recovery efforts. To contribute to future flood management, this paper proposes the use of building simulations and biological models to predict the risk of microbial contamination in typical UK buildings. We review the state of the art with regard to biological contamination following flooding, relevant building simulation, simulation-linked microbial modelling, and current practical considerations in flood remediation. Using the city of London as an example, a methodology is proposed that uses GIS as a platform to integrate drying models and microbial risk models with the local building stock and flood models. The integrated tool will help local governments, health authorities

Gas prices in the UK: markets and insecurity supply

International Nuclear Information System (INIS)

Wright, P.

2006-01-01

In this article, Professor P. Wright argues that the high and volatile gas price experienced by UK consumers over the last 3 years are the result of the extend of liberalization in the UK - which has made UK prices much more sensitive to insecurities of supply. Businesses pay the cost of this, straightaway, while the strategies which gas companies have used to respond to heightened price risks means domestic consumers also bear the cost of higher supply-markups. The prospect of high levels of demand in bad winters then just adds to price risk and its associated costs. The implication of this analysis is that it is illogical for the UK's regulator and government to blame the UK's high prices on the slow progress of liberalization in the rest of Europe - greater liberalization in Europe might simply replicate the UK's price difficulties throughout Europe

The UK gas market in transition to competition

International Nuclear Information System (INIS)

Helm, D.

1997-01-01

Virtually every aspect of the UK gas market is currently experiencing rapid change and major uncertainties. The fast-track to full competition in 1998 requires a new customer-handling infrastructure, new rules and new marketing strategies.The introduction of competition in the UK is proving more complex than most of its architects assumed. The UK provides considerable evidence not only on market design but also the management of the transitional process. The path from a state-owned monopoly through privatisation to competition is overviewed, and some of the lessons are considered which other countries (and the European Commission) contemplating reforms may glean from the UK experience.

Our cities, from megalopolis to rural commune, are systems of an extraordinary technological and human complexity. Their balance is threatened by the growing population and rarefaction of resources. Massive urbanization endanges the environment, while global climate change, through natural hazards generated (climatic, hydrological and geological), threats people and goods. Connect the city, that is to say, design and spread systems able to route, between multiple actors, a very large amount of heterogeneous information natures and analyzed for various purposes, is at the heart of the hopes to make our cities more sustainable: climate-resilient, energy efficient and actresses of the energy transition, attractive to individuals and companies, health and environment friendly. If multiple players are already aware of this need, progress is slow because, beyond the only connectivity, it is the urban intelligence that will create the sustainable city, through coordinated capabilities of Perception, Decision and Action: to measure phenomena; to analyze their impact on urban sustainability in order to define strategies for improvement; to effectively act on the cause of the phenomenon. In this very active context with a strong societal impact, the Sense-City project aims to accelerate research and innovation in the field of sustainable city, particularly in the field of micro and nanosensors. The project is centered around a "mini climatic City", a unique mobile environmental chamber in Europe of 400m² that can accommodate realistic models of city main components, namely buildings, infrastructures, distribution networks or basements. This R&D test place, available in draft form from January 2015 and in finalized version in 2016, will allow to validate, in realistic conditions, innovative technologies performances for the sustainable city, especially micro- and nano-sensors, at the end of their development laboratory and upstream of industrialization.

The authors analyze soil relations with other elements of the city ecosystem (the position in the landscape, soil-forming rocks and lithology, vegetation and its state) to develop the legend and map of soils in the City of Birobidzhan (scale 1:25 000). The focus of study is the morphological structure of urban soils with different degree of disturbance of these relations under the impact of technical effects, economic and recreational activities of the city population. The soil cover structure is composed of four large ecological groups of soils: natural untransformed, natural with a disturbed surface, anthropogenic soils and technogenic surface formations. Using cartometry of the mapped soil contours the authors created the scheme of soil-ecological city zoning, which in a general way depicts the state of soil ecological functions in the city as well as identified zones of soils with preserved, partially and fully distured ecological functions and zones of local geochemical anomalies at the initial formation stage (environmental risk zones).

How much should I eat? A comparison of suggested portion sizes in the UK.

To identify and compare suggested food portion sizes in UK schemes. The study collated and compared suggested portion sizes from selected UK schemes intended both for general advice and weight-loss advice. Portion size schemes were included if they were relevant to the UK, provided actual portion size information, were intended for adults and were obtainable from the public domain in November 2010. Included schemes were from the food industry, non-governmental organisations and health-care professionals. Suggested portion sizes of foods occurring in at least one scheme for general advice and at least one scheme for weight loss were included. Own brand on-pack portion size labelling from a large UK-wide supermarket was added to represent portion size advice from UK food retailers. Not applicable. The suggested portion sizes in the weight-loss advice schemes were often concordant, as were the general advice schemes, except one general advice scheme from a non-governmental organisation which was more closely aligned with the portion sizes for weight loss. Overall there were substantial discrepancies between suggested portion sizes for muesli and crunchy breakfast cereals, rice, pasta and potatoes, meat, fish and pulses, whereas portion sizes for cooked vegetables, dried fruit, some breakfast cereals and cheese were broadly consistent. There is a lack of consistency in the portion sizes communicated to the public. An independent and authoritative scheme of suggested portion sizes for all foods, with distinct recommendations for general advice and for weight-loss advice, could be of benefit.

Multi-geohazards of Ende city area

Full Text Available http://dx.doi.org/10.17014/ijog.vol2no4.20073The Ende City is a steep mountainous area, of which the height of their peaks are above 1500 m asl. It has the limited extent of plain places, without coastal plains. Due to this condition, large parts of the area are vulnerable to mass-movements mainly debris flows, rock-falls and shallow translational and rotational landslides. On the other hand, Flores Island is a segment of the Banda Arc that contains eleven very active volcanoes and numerous inactive volcanic cones. Two of them, Mount Iya and Mount Kelimutu are included to Ende Regency. The northern foot of Mount Iya is only about 1 km away from the southern outskirts of Ende city. But the presence of Mount Meja and Mount Roja as the barrier, and the orientation of the active crater (K2, the highly explosive eruption of Iya Volcano may not directly endanger the city of Ende. Most pyroclastic flows of previous eruptions and other eruptive material emplaced into the sea, but due to a short horizontal distance between Mount Iya and Ende City, the ejected rock fragments can endanger the city of Ende especially its southern parts. A crack has developed around the active crater (K2 of Iya Volcano. It seems that the crack indicates a major weakness within the volcano, which could result in a giant landslide, entering the sea in future eruptions of Iya Volcano. The kinetic energy which is transmitted through the water may probably generate a tsunami. The Ende City also experienced significant damages in the 1992 earthquake. Luckily this city is located on a solid rock instead of alluvial sediments which can potentially undergo liquefaction.  

Motivation, expectations and the gender pay gap for UK graduates

OpenAIRE

Arnaud Chevalier

2004-01-01

Focussing on recent UK graduates, a wage gap of 12% is found. The unexplained component of the gap is small and a large fraction of the gap can be explained by subject choice, job characteristics, motivation and expectation variables. Motivation and expectations account for 44% of the explained gap, thus most studies over-estimate the unexplained component of the gender wage gap. Following stereotypes, women tend to be more altruistic and less career oriented than men, character traits that a...

Determinants of urban sprawl in European cities.

Science.gov (United States)

Oueslati, Walid; Alvanides, Seraphim; Garrod, Guy

2015-07-01

This paper provides empirical evidence that helps to answer several key questions relating to the extent of urban sprawl in Europe. Building on the monocentric city model, this study uses existing data sources to derive a set of panel data for 282 European cities at three time points (1990, 2000 and 2006). Two indices of urban sprawl are calculated that, respectively, reflect changes in artificial area and the levels of urban fragmentation for each city. These are supplemented by a set of data on various economic and geographical variables that might explain the variation of the two indices. Using a Hausman-Taylor estimator and random regressors to control for the possible correlation between explanatory variables and unobservable city-level effects, we find that the fundamental conclusions of the standard monocentric model are valid in the European context for both indices. Although the variables generated by the monocentric model explain a large part of the variation of artificial area, their explanatory power for modelling the fragmentation index is relatively low.

The Environmental Impacts of Electric Bikes in Chinese Cities

Electric bikes have captured a large share of trips in many Chinese cities. They provide high levels of mobility and use little energy, two things that Chinese cities need to optimize. However, these benefits come at a cost, particularly emissions from primarily coal power plants and increased lead waste from battery use. Chinese policy makers are struggling with developing appropriate policy that maximizes modal options and mobility and minimizes environmental impacts. Electric bikes us...

Talat, B.; Ahsan-Ullah

2005-01-01

The growth of mega-cities in recent times has brought to the fore a large number of issues with respect environmental conditions such as development of slum areas, poor localities, solid waste disposal, management of sewage system, lack of open spaces and health facilities. One of the major issues effecting environment proper disposal of sewage and development of sewage system including recycling of sewage water and its use. The heavy pressure of population calls for adequate provision of sewage disposal in the new areas and remodeling of systems in the old areas of the cities to ensure a pollution-free environment. Recycling of sewage and prevention of sewage discharge into natural water channels and the sea has to be undertaken on urgent bases. The paper seeks to outline the present status of sewage system of the city of Karachi, the problems involved and the proposals for management and development of the system compatible with the need and requirement of mega-city population.

Fossil resource trade balances. Emerging trends for the UK

International Nuclear Information System (INIS)

Papathanasopoulou, Eleni; Jackson, Tim

2008-01-01

The aim of this paper is to examine the extent to which the UK can be classified as a net importer of fossil resources and a creator of pollution havens abroad between 1968 and 2000. Using input-output techniques and a derived Resource Flow Classification System, both the physical trade balance (PTB) and pollution trade balance (UTB) associated with fossil resource use are computed. The PTB shows that between 1968 and the early 1980's the UK is presented as a net importer of direct fossil resource flows. Between 1984 and 2000, the UK is identified as a net exporter of direct fossil resources. These trends are primarily explained by the UK's discovery and commercial production of North Sea oil and gas fields in the late 1970s. On the other hand, the UTB shows that over the whole period the indirect used flows attributable to the UK's exports are higher than those attributable to its imports. These findings suggest that the UK did not create pollution havens abroad from the use of fossil resources between 1968 and 2000. However, it is noticeable in both cases that from 1995 the UK's position as a net exporter has been decreasing considerably. Maturing North Sea oil and gas fields set against increasing demands for fossil fuels and imported goods is signalling a return to the UK's pre-1984 dependence on direct imported fossil resources and the possible creation of pollution havens abroad. Knowledge of these trends contributes to the evidence base for the UK's changing import and export structure and the potential environmental repercussions at home and abroad. (author)

Demand reduction in the UK - with a focus on the non-domestic sector

International Nuclear Information System (INIS)

Toke, D.

2007-01-01

A demand reduction strategy is considered in the context of the UK and in the light of the UK Government's 2006 Energy Review. This paper discusses how a mechanism - a Demand Reduction Obligation (DRO) - can be established to achieve radical energy demand reduction targets in electricity and gas use in the industrial, commercial and public administration sectors. A DRO would require energy suppliers to invest in energy-saving measures so as to reduce energy demand in these sectors. The investment for this activity would be funded by energy suppliers who would increase prices in order to cover the cost of achieving the carbon reductions. Public opinion surveys suggest that a large proportion of the public would prefer to support demand reduction measures compared to other energy options. It may be practical to deliver carbon emission reductions equivalent to around 30% of emissions from the UK electricity sector over a 15-year period through a broad-based demand reduction strategy. Demand reduction is considered in the context of an assessment of costs and resources available from other low carbon options including renewable energy and nuclear power. [Author

Making the link: climate policy and the reform of the UK construction industry

International Nuclear Information System (INIS)

Sorrell, Steve

2003-01-01

This paper explores the barriers to energy efficiency in the construction of non-domestic buildings in the UK. The source of the barriers is argued to lie in the organisation of the construction industry, including the linear design process, the reliance on cost-based competitive tendering and the incentives placed upon different actors. The consequences include oversizing of equipment, reduced quality, neglect of whole life costs and lack of integrated design. Each of these problems can usefully be interpreted using concepts from the new institutional economics. While the barriers are well known to construction industry specialists, they are relatively neglected in the academic literature on energy policy. Furthermore, conventional policy measures such as building regulations leave these barriers largely untouched. The UK construction industry is currently undergoing a series of reforms which aim to change the relationship between different actors and to achieve improvements in product quality and productivity. While these reforms have the potential to address many of the barriers, the reform agenda makes practically no reference to sustainability. This paper argues that climate policy objectives must be integrated into the reform agenda if the UK is to begin the transition to a low carbon built environment

Influence on UK Nuclear Regulation from the Fukushima Daiichi Accident

International Nuclear Information System (INIS)

Savage, R.

2016-01-01

This paper provides an overview of the UKs response to the Fukushima Daiichi Accident and highlights the influence that this has had on UK nuclear regulation since March 2011. ONR’s Incident Suite was staffed from the first day of the accident and remained active on a 24 hours basis for over two weeks. The purpose was to provide advice to the UK government specifically prompt assurance of why this accident couldn’t take place in the UK and practical advice in relation to the 17,000 UK nationals in Japan at that time. In the early phase of the accident ONR took part in international cooperation with the US, Canadian and French regulators in order to determine the actual technical status of the Fukushima Daiichi power plant units. The UK Secretary of State requested that the ONR Chief Inspector identify any lessons to be learnt by the UK nuclear industry and in doing so cooperate and coordinate with international colleagues. The Interim report was produced (May 2011) this focused on civil NPP’s, provided background to radiation, technology and regulations. This report compared the Japan situation with the UK and identified 11 conclusions and 26 recommendations.

Investigation of Quality and Reclamation of Urban Storm Runoff in City of Shiraz

Mohammad Parvinnia

2008-06-01

Full Text Available Urban storm runoff is considered as a potentially reclaimable and valuable resource in many arid and semiarid areas, in Iran. Urban storm runoff in Shiraz is collected mainly by Khoshk River and transported to the Maharloo Lake without any treatment or reclamation. In this study, storm runoff quality and the possibility for its reclamation from different parts of the city in certain canals and pipes are investigated. The quality of the first flush in three relatively large and small suburban areas with different land uses is studied. For the purposes of this study, three stations were considered: one near the downstream end of the city on Khoshk River with a relatively large watershed, one in the middle of the city where street runoff is the main constituent of the flush, and a third one near the western outskirts of the city with relatively small mainly residential watershed.

Inward migration to the UK remains topical and controversial as numbers continue to increase. Many immigrants have specific health care needs and may shoulder a large burden of infectious disease. Imposition of legal constraints can have a huge impact on the medical care afforded to immigrants. Currently UK policy is to treat, free of charge and with NHS resources, those who fulfil specific criteria. However an increasing number are being asked to pay for their treatment. Many health care professionals are confused as to current legal restrictions and require guidance on the associated ethical issues. We concentrate on provision of care to HIV positive individuals and use cases to illustrate some of the issues. However these issues are equally pertinent to practitioners in all branches of medicine.

2018-03-01

Serui City in Papua Province has many unique characters and must be maintained for the sake of the continuity of its identity. However, this city still lacks the facility and depend on other areas. Accordingly, it becomes vulnerable. The wholeness of the city is not just by having strong character but also having strength regarding vitality. The loss of it can affect the character and even eliminate it. Cities and people have many similarities regarding character and vitality. Therefore, there is a chance to solve the problems in the city using the similar approach to treat the human. We called city personification methods as problem-solving to the city. It means that we treat the city as a human being so that the problem can be solved as the human’s treatment. The personification of this city is conducted because of the many treatments that have proven effective in humans and may also be powerful to manifest in city. The personification makes the design will only focus on the particular networks and not on the whole “body,” remain in the hope for strengthening (maintain and improve) the quality of wholeness (character and vitality) city which in this case is Serui.

Development and production prospects for oil and gas from the UK continental shelf after the Gulf crisis: a financial simulation

A large computerized financial model has been developed to simulate the future exploitation of oil and gas in the UK north sea. Primary inputs into the model include all the publicity available information on currently producing fields relating to their historic and expected production rates, investment, operating and abandonment costs. Information has also been gathered on all new discoveries which have not yet been developed and estimates made of the timing of their development, the commencement of production and costs. Three oil price scenarios base, low and high, have been used in the analysis which extends to the year 2015. The results are presented for two major regions, the central and northern waters and the Southern Gas Basin, including the Irish Sea. Very large numbers of discovered but undeveloped oil and gas fields exist in the UK continental shelf substantial numbers of which could be developed in the event of a very modest real growth in oil and gas prices. The considerable sensitivity of development to movements in oil prices is brought out by the analysis of the three scenarios. (UK)

UK has been facing housing crisis due to the rising price of the property on sale. This paper will look into the viability of 3D printing technology as an alternative way for house construction on UK. The analysis will be carried out based on the data until the year of 2014 due to limited resources availability. Details cost breakdown on average size house construction cost in UK were analysed and relate to the cost viability of 3D printing technology in reducing the house price in UK. It is found that the 3D printing generates saving of up to around 35% out of total house price in UK. This cost saving comes from the 3D printed construction of walls and foundations for material and labour cost.

Post-carbon Society: Pioneering Cities

International Nuclear Information System (INIS)

Emelianoff, Cyria; Mor, Elsa

2013-01-01

In 2009 a programme was launched, steered jointly by the Foresight Mission of the French Ecology Ministry and by the French Environment and Energy Management Agency (ADEME), called 'Rethinking Cities in a Post-carbon Society'. The programme's work is still on-going towards a final report planned for 2013. The idea of a transition towards a 'post-carbon' society embraces four main objectives: the reduction of greenhouse gases by 2050 to one quarter of their 1990 levels, virtual autonomy in respect of carbon-based energies (oil, gas and coal), an adequate capacity for adaptation to climate change and, lastly, greater attention to situations of energy precariousness . As part of the dossier Futuribles is devoting, this month, to this programme, Cyria Emelianoff and Elsa Mor show, in this article, how certain cities have gradually taken this subject on board, developing -often thanks to civil society initiatives and the emergence of networks of pioneering cities at the European level- highly ambitious strategies of transition towards less carbon energy consumption and lower greenhouse gas emissions. Here they outline two concrete cases of cities that are highly active in this field, Hanover and Bristol, showing their aims, the strategies deployed, the levers used and the results obtained. They particularly stress the importance played in these two transitions by the economic and environmental departments coming together on the question, and also by the development of 'multi-partner' approaches. They are, nevertheless, critical of the difficulties in establish - ing proper 'multi-scale climate governance' involving -above and beyond these pioneering cities- the regional, national, European and international levels, with a view to a more large-scale post-carbon transition.

UK's greenhouse gas emissions have increased in 2004 and 2005 and the country is no longer self-sufficient with respect to energy supplies. In front of global warming and energy security threats, UK is reconsidering its energy policy. Based on low carbon solutions, the UK energy economy tries to valorize renewable energies: recovery of methane, combined combustion of biomass and fossil fuels, development of offshore wind and wave power, etc. One reason is also for UK to locally recover part of its lost autonomy thanks to energy decentralization. Since 2006, public hearings have been launched to consider a renewal of the present nuclear park, a development of offshore gas storage and LNG terminal facilities and a promotion of cogeneration systems.

Branding Cities, Changing Societies

DEFF Research Database (Denmark)

Ooi, Can-Seng

Societal changes are seldom discussed in the literature on city branding. The time element is important because it highlights the fluctuating reality of society. The city brand message freezes the place but in fact, the city branding exercise is a continuous process. Society emerges too. City...... brands are supposed to accentuate the uniqueness of the city, be built from the bottom-up and reflect the city's identity. This paper highlights three paradoxes, pointing out that city branding processes can also make cities more alike, bring about societal changes and forge new city identities. A city...... branding campaign does not just present the city, it may change the city. The relationships between the branding exercise and the city are intertwined in the evolution of the place....

A tale of three cities: decarbonising Auckland, Sydney and Christchurch and consequences for other cities around the world

OpenAIRE

Byrd, Hugh

Sydney and Auckland have similar climates, cultures and urban form. However, methods for reducing carbon emissions and energy use are completely different. Auckland has low carbon buildings due to the large proportion of renewable energy in the electricity supply. However, it is a car dependent city and lacks resilience in transport energy. Sydney has high carbon buildings due to the large proportion of coal used to generate electricity. However, its public transport system is more resilient ...

The immediate background to this paper is the downgrade of the U.K.'s credit rating in February 2013, the market's view that this should have occurred earlier and the emphasis in fiscal policy on reducing debt rather than recovery from recession. We propose a measure of the U.K. sovereign credit rating based on an open economy macroeconomic model that is simple to compute and easily automated. Whether based on an ad hoc debt-GDP limit or a DSGE model of an open economy, our measure downgrades...

Rethinking GIS Towards The Vision Of Smart Cities Through CityGML

Guney, C.

2016-10-01

Smart cities present a substantial growth opportunity in the coming years. The role of GIS in the smart city ecosystem is to integrate different data acquired by sensors in real time and provide better decisions, more efficiency and improved collaboration. Semantically enriched vision of GIS will help evolve smart cities into tomorrow's much smarter cities since geospatial/location data and applications may be recognized as a key ingredient of smart city vision. However, it is need for the Geospatial Information communities to debate on "Is 3D Web and mobile GIS technology ready for smart cities?" This research places an emphasis on the challenges of virtual 3D city models on the road to smarter cities.

Slade, Ingrid; Subramanian, Deepak N; Burton, Hilary

2016-08-01

Genomics education in the UK is at an early stage of development, and its pace of evolution has lagged behind that of the genomics research upon which it is based. As a result, knowledge of genomics and its applications remains limited among non-specialist clinicians. In this review article, we describe the complex landscape for genomics education within the UK, and highlight the large number and variety of organisations that can influence, direct and provide genomics training to medical professionals. Postgraduate genomics education is being shaped by the work of the Health Education England (HEE) Genomics Education Programme, working in conjunction with the Joint Committee on Genomics in Medicine. The success of their work will be greatly enhanced by the full cooperation and engagement of the many groups, societies and organisations involved with medical education and training (such as the royal colleges). Without this cooperation, there is a risk of poor coordination and unnecessary duplication of work. Leadership from an organisation such as the HEE Genomics Education Programme will have a key role in guiding the formulation and delivery of genomics education policy by various stakeholders among the different disciplines in medicine. © 2016 Royal College of Physicians.

The Good City: Design for Sustainability

Directory of Open Access Journals (Sweden)

Victor Margolin

Full Text Available Today, we are faced with many problems to which designers can contribute solutions. Action can take place at three levels: the micro level, that of individual action; the meso level is the level of groups where the individual may still have some influence; and the macro level includes governments, international organizations, and large companies. At the outer limits of the meso level is the city, which is still potentially capable of adopting coherent policies for change. There are many good ideas about urban design although it is rare to find a city that has integrated a large number of them into a holistic system. What is called for is a systemic approach to these initiatives that will form the basis of a new theory of sustainable urban planning. Such a theory would take into account the following factors as well as others: 1 producing and distributing food; 2 recycling soft and hard waste; 3 providing shelter and eliminating homelessness; 4 microlending and stimulating cooperative businesses; and 5 providing alternative energy.

To estimate the annual cost of treating pressure ulcers in the UK. Costs were derived from a bottom-up methodology, based on the daily resources required to deliver protocols of care reflecting good clinical practice. Health and social care system in the UK. Patients developing a pressure ulcer. A bottom-up costing approach is used to estimate treatment cost per episode of care and per patient for ulcers of different grades and level of complications. Also, total treatment cost to the health and social care system in the UK. The cost of treating a pressure ulcer varies from pound 1,064 (Grade 1) to pound 10,551 (Grade 4). Costs increase with ulcer grade because the time to heal is longer and because the incidence of complications is higher in more severe cases. The total cost in the UK is pound 1.4- pound 2.1 billion annually (4% of total NHS expenditure). Most of this cost is nurse time. Pressure ulcers represent a very significant cost burden in the UK. Without concerted effort this cost is likely to increase in the future as the population ages. To the extent that pressure ulcers are avoidable, pressure damage may be indicative of clinical negligence and there is evidence that litigation could soon become a significant threat to healthcare providers in the UK, as it is in the USA.

Head, Michael G; Brown, Rebecca J; Clarke, Stuart C

2018-01-01

Infectious disease remains a significant burden in the UK and the focus of significant amounts of research investment each year. The Research Investments in Global Health study has systematically assessed levels of funding for infection research, and here considers investment alongside UK burden of individual infectious diseases. The study included awards to UK institutions between 1997 and 2013 that were related to infectious disease. Awards related to global health projects were excluded here. UK burden data (mortality, years lived with disability, and disability adjusted life years) was sourced from the Global Burden of Disease study (IHME, USA). Awards were categorised by pathogen, disease, disease area and by type of science along the research pipeline (pre-clinical, phase I-III trials, product development, public health, cross-disciplinary research). New metrics present relative levels of funding by comparing sum investment with measures of disease burden. There were 5685 relevant awards comprising investment of £2.4 billion. By disease, HIV received most funding (£369.7m; 15.6% of the total investment). Pre-clinical science was the predominant type of science (£1.6 billion, 68.7%), with the UK Medical Research Council (MRC) the largest funder (£714.8 million, 30.1%). There is a broad temporal trend to increased fundingper annum. Antimicrobial resistance received (£102.8 million, 4.2%), whilst sepsis received £23.6 million (1.0%). Compared alongside disease burden, acute hepatitis C and measles typically were relatively well-funded, whilst pneumonia, syphilis and gonorrhoea were poorly-funded. The UK has a broad research portfolio across a wide range of infectious diseases and disciplines. There are notable strengths including HIV, some respiratory infections and in pre-clinical science, though there was less funding for UK-relevant trials and public health research. Compared to the UK burden of disease, syphilis, gonorrhoea and pneumonia appear

Regulation of nuclear power in the UK after Chernobyl

International Nuclear Information System (INIS)

Ryder, E.A.

1987-01-01

The essential philosophy underlying safe nuclear power in the UK is to establish a safe design and then monitor the manufacture, construction, commissioning, operation and maintenance to ensure that the safe design intent is not violated either deliberately or unintentionally. In the UK any commercial nuclear installation must have a nuclear site licence. The Nuclear Installations Inspectorate (NII) is the agency responsible for granting licences and ensuring the safe design and operation of the installation by the licensee. The way in which the NII does this for the 27 licensed sites that it regulates in the UK is explained. This covers plant assessment and site inspection. Following the accident at Chernobyl the NII reviewed the way in which it regulates nuclear power in the UK. Some changes in specific areas were recommended but no changes in the general philosophy were considered necessary. (UK)

Five years of nitrogen dioxide measurement with diffusion tube samplers at over 1000 sites in the UK

Science.gov (United States)

Stevenson, Ken; Bush, Tony; Mooney, Diane

In 1993, a large (>1000 monitoring sites) co-ordinated monitoring network for nitrogen dioxide, using diffusion tube samplers, was established in urban areas throughout the UK. The primary aim of this network is to assess the spatial and temporal distribution of NO 2 throughout the UK and highlight areas of high concentration which may require more detailed monitoring with automatic analysers. This paper presents a summary of the results for the first 5-years of monitoring, 1993-1997 inclusive. The network has shown that highest concentrations occur in London and urban areas of Yorkshire and Humberside and the East and West Midlands of the UK. Averaged over the whole of the UK, NO 2 concentrations have been remarkably similar for most of the 5 years, though a significant decrease was observed at urban background locations in 1997. Overall, average NO 2 concentrations during 1997 were 23 ppb at kerbside locations and 13 ppb at urban background locations. The results of the network have been used by the Department of Environment, Transport and the Regions as one of the criteria for the selection of priority areas for expansion of the UK Automatic Urban Network in recent years. Extensive quality assurance and control procedures incorporated into the network ensure that the estimated accuracy of the data is broadly comparable with the accuracy requirement for indicative monitoring specified in the EU "daughter" Directive for NO2 (±25%) . The complete dataset of results for the network can be found on the world wide web at http://www.environment.detr.gov.uk/airq/aqinfo.htm.

Medan City: Informality and the Historical Global City

2018-05-01

As projected by UN that two-thirds of Indonesia’s population will live in urban areas by 2050, rapid urbanization is happening in Indonesian cities. Initial research on eight Indonesian Cities (which includes Medan, Jatinegara, Bandung, Surakarta, Yogyakarta, Surabaya, Balikpapan, and Manado) by Tunas Nusa Foundation since 2012 shows that urbanization of each city has happened throughout history creating cultural, economic, and environmental networks that are distinct from one city to another. While the networks remain until today and continuously shapes the urban agglomeration pattern, not all parts of the city could undergo subsequent development that confirms the existing pattern, leading to the creation informality. Nor could it make future planning that comprehends the nature of its integrated urban dynamic beyond its current administrative authority. In this paper, we would like to share our study for Medan, North Sumatra as it shows a portrait of a city with a long relationship to a global network since the Maritime trade era. Medan has become home to many ethnic groups which have sailed and migrated as part of a global economic agenda creating a strong economic network between port cities along the Malacca Strait. The city has kept its role in the global economic network until today, to name a few, becoming the frontier for the Indonesia-Malaysia-Thailand Growth Triangle. While we celebrate Medan’s potential to become a global city with major infrastructure development as well as cultural assets as its advantage in the future, we argue that microscale cohesion supported by government policy in agreed planning documents are fundamental for the city to thrive amidst the challenges it is facing. Yet, these cultural assets, as well as micro scale cohesion in Medan City today, are still undermined. Thus, informality in Medan exists as result of ignorance and marginalization of certain socio-cultural groups, abandoning places and identity, as well as the

A survey of the practice and management of radiotherapy linear accelerator quality control in the UK.

2012-11-01

The objective of this study was to determine current radiotherapy linear accelerator quality control (QC) practice in the UK, as a comparative benchmark and indicator of development needs, and to raise awareness of QC as a key performance indicator. All UK radiotherapy centres were invited to complete an online questionnaire regarding their local QC processes, and submit their QC schedules. The range of QC tests, frequency of measurements and acceptable tolerances in use across the UK were analysed, and consensus and range statistics determined. 72% of the UK's 62 radiotherapy centres completed the questionnaire and 40% provided their QC schedules. 60 separate QC tests were identified from the returned schedules. There was a large variation in the total time devoted to QC between centres: interquartile range from 13 to 26 h per linear accelerator per month. There has been a move from weekly to monthly testing of output calibration in the last decade, with reliance on daily constancy testing equipment. 33% of centres thought their schedules were in need of an update and only 30% used risk-assessment approaches to determine local QC schedule content. Less than 30% of centres regularly complete all planned QC tests each month, although 96% achieve over 80% of tests. A comprehensive "snapshot" of linear accelerator QC testing practice in the UK has been collated, which demonstrates reasonable agreement between centres in their stated QC test frequencies. However, intelligent design of QC schedules and management is necessary to ensure efficiency and appropriateness.

Modelling potential production of macroalgae farms in UK and Dutch coastal waters

2018-02-01

Full Text Available There is increasing interest in macroalgae farming in European waters for a range of applications, including food, chemical extraction for biofuel production. This study uses a 3-D numerical model of hydrodynamics and biogeochemistry to investigate potential production and environmental effects of macroalgae farming in UK and Dutch coastal waters. The model included four experimental farms in different coastal settings in Strangford Lough (Northern Ireland, in Sound of Kerrera and Lynn of Lorne (north-west Scotland and in the Rhine plume (the Netherlands, as well as a hypothetical large-scale farm off the UK north Norfolk coast. The model could not detect significant changes in biogeochemistry and plankton dynamics at any of the farm sites averaged over the farming season. The results showed a range of macroalgae growth behaviours in response to simulated environmental conditions. These were then compared with in situ observations where available, showing good correspondence for some farms and less good correspondence for others. At the most basic level, macroalgae production depended on prevailing nutrient concentrations and light conditions, with higher levels of both resulting in higher macroalgae production. It is shown that under non-elevated and interannually varying winter nutrient conditions, farming success was modulated by the timings of the onset of increasing nutrient concentrations in autumn and nutrient drawdown in spring. Macroalgae carbohydrate content also depended on nutrient concentrations, with higher nutrient concentrations leading to lower carbohydrate content at harvest. This will reduce the energy density of the crop and thus affect its suitability for conversion into biofuel. For the hypothetical large-scale macroalgae farm off the UK north Norfolk coast, the model suggested high, stable farm yields of macroalgae from year to year with substantial carbohydrate content and limited environmental effects.

the contemporary city and maybe the understanding of the city needs to be updated in some areas, before we are able to do so. In this paper, the focus will be directed towards two themes which become present with the Shrinking Cities phenomenon and therefore seems important to discuss in order to understand...... the concept of Shrinking Cities. These two themes may affect the understanding of the existing city theory. The first theme is concerned with the physical understanding of the city where the traditional assumption about the city as a high density area, with buildings as the dominant structure, is questioned....... Here the concept of the city as an urban landscape will be introduced. The second theme points to the need for a discussion regarding the object of our planning when developing the cities. Previously, the purpose of city development has been growth and expansion, but with the Shrinking Cities...

A UK perspective on recycling

International Nuclear Information System (INIS)

Williams, T.

1991-01-01

The United Kingdom, through the recycling of depleted uranium from Magnox reactors into Advanced Gas-cooled Reactor (AGR) fuel, has already recycled significant quantities of reprocessed material in reactors owned by Nuclear Electric plc and Scottish Nuclear Limited. This AGR fuel has been satisfactorily irradiated and discharged over a decade or more, and will be reprocessed in the new Thermal Oxide Reprocessing Plant (THORP), currently under construction in the UK. British Nuclear Fuels plc (BNFL) and the UK Atomic Energy Authority (UKAEA) have also been exploiting the potential of plutonium recycled in mixed oxide (MOX) fuel, which they have been making since 1963. All of the UK nuclear companies are committed to further recycling of Magnox depleted uranium during the 1990s, and it is anticipated that oxide recycling will also become firmly established during the next decade. British Nuclear Fuels and Urenco Ltd, as the providers of fuel cycle services, are developing an infrastructure to close the fuel cycle for oxide nuclear fuel, using both the uranium and plutonium arising from reprocessing.

Changes in the number of nesting pairs and breeding success of theWhite Stork Ciconia ciconia in a large city and a neighbouring rural area in South-West Poland

Directory of Open Access Journals (Sweden)

Kopij Grzegorz

2017-12-01

Full Text Available During the years 1994–2009, the number of White Stork pairs breeding in the city of Wrocław (293 km2 fluctuated between 5 pairs in 1999 and 19 pairs 2004. Most nests were clumped in two sites in the Odra river valley. Two nests were located only cca. 1 km from the city hall. The fluctuations in numbers can be linked to the availability of feeding grounds and weather. In years when grass was mowed in the Odra valley, the number of White Storks was higher than in years when the grass was left unattended. Overall, the mean number of fledglings per successful pair during the years 1995–2009 was slightly higher in the rural than in the urban area. Contrary to expectation, the mean number of fledglings per successful pair was the highest in the year of highest population density. In two rural counties adjacent to Wrocław, the number of breeding pairs was similar to that in the city in 1994/95 (15 vs. 13 pairs. However, in 2004 the number of breeding pairs in the city almost doubled compared to that in the neighboring counties (10 vs. 19 pairs. After a sharp decline between 2004 and 2008, populations in both areas were similar in 2009 (5 vs. 4 pairs, but much lower than in 1994–1995. Wrocław is probably the only large city (>100,000 people in Poland, where the White Stork has developed a sizeable, although fluctuating, breeding population. One of the most powerful role the city-nesting White Storks may play is their ability to engage directly citizens with nature and facilitate in that way environmental education and awareness.

Ascroft-Hutton, H.W.

2001-01-01

The UK has facilities for the production of uranium hexafluoride, its enrichment, conversion into fuel and for the subsequent reprocessing of irradiated fuel and closure of the fuel cycle. All of these facilities must be licensed under UK legislation. HM Nuclear Installations Inspectorate has delegated powers to issue the licence and to attach any conditions it considers necessary in the interests of safety. The fuel cycle facilities in the UK have been licensed since 1971. This paper describes briefly the UK nuclear regulatory framework and the fuel cycle facilities involved. It considers the regulatory practices adopted together with similarities and differences between regulation of fuel cycle facilities and power reactors. The safety issues associated with the fuel cycle are discussed and NII's regulatory strategy for these facilities is set out. (author)

Public health is often affected by societal decisions that are not primarily about health. Climate change mitigation requires intensive actions to minimise greenhouse gas emissions in the future. Many of these actions take place in cities due to their traffic, buildings, and energy consumption. Active climate mitigation policies will also, aside of their long term global impacts, have short term local impacts, both positive and negative, on public health. Our main objective was to develop a generic open impact model to estimate health impacts of emissions due to heat and power consumption of buildings. In addition, the model should be usable for policy comparisons by non-health experts on city level with city-specific data, it should give guidance on the particular climate mitigation questions but at the same time increase understanding on the related health impacts and the model should follow the building stock in time, make comparisons between scenarios, propagate uncertainties, and scale to different levels of detail. We tested The functionalities of the model in two case cities, namely Kuopio and Basel. We estimated the health and climate impacts of two actual policies planned or implemented in the cities. The assessed policies were replacement of peat with wood chips in co-generation of district heat and power, and improved energy efficiency of buildings achieved by renovations. Health impacts were not large in the two cities, but also clear differences in implementation and predictability between the two tested policies were seen. Renovation policies can improve the energy efficiency of buildings and reduce greenhouse gas emissions significantly, but this requires systematic policy sustained for decades. In contrast, fuel changes in large district heating facilities may have rapid and large impacts on emissions. However, the life cycle impacts of different fuels is somewhat an open question. In conclusion, we were able to develop a practical model for city

Water supply and disposal in the City of Kiev following the accident at Chernobyl nuclear power plant

International Nuclear Information System (INIS)

Tzarik, N.

1990-01-01

Kiev is the capital of the Ukrainian Soviet Socialist Republic, and is the USSR's third largest city, with a population of 2.7 million people. The city water supply is dependent on three sources; two surface ones, i.e. the rivers Dniepr and Desna, and one underground one. The average total water consumption of the city amounts to 1.5 x 10 6 m 3 /day. The Chernobyl Power Plant accident posed a threat to the normal operation of the Kiev water supply system. In the circumstances, it became necessary to adopt the most urgent measures aimed at ensuring a continuous delivery of potable water to the city under conditions of the potential radioactive contamination of water supply sources. Round-the-clock monitoring of the radioactivity of the water source has taken place, including the control of water quality at various treatment stages, the variation of radioactivity of different filter loading materials and the radioactivity of waste waters, sludge and silt. The main concern was the threat of contamination of the Kiev reservoir. However the concentration of radionuclides in the drinking water supply has not exceeded the permissible limits. Various requirements for the water supply in the face of radioactive contamination are mentioned such as several water supplies, one of which is preferably an underground source, flexible conditions of water treatment and continuous radiation monitoring of the water supply (UK)

Misselbrook, T. H.; Van Der Weerden, T. J.; Pain, B. F.; Jarvis, S. C.; Chambers, B. J.; Smith, K. A.; Phillips, V. R.; Demmers, T. G. M.

Ammonia (NH 3) emission inventories are required for modelling atmospheric NH 3 transport and estimating downwind deposition. A recent inventory for UK agriculture, estimating emission as 197 kt NH 3-N yr -1, was constructed using 1993 statistical and census data for the UK. This paper describes the derivation of the UK-based emission factors used in the calculation of that emission for a range of livestock classes, farm practices and fertiliser applications to agricultural land. Some emission factors have been updated where more recent information has become available. Some of the largest emission factors derived for each farming practice include 16.9 g NH 3-N dairy cow -1 d -1 for grazing, 148.8 g NH 3-N liveweight unit -1 yr -1 for housed broilers and 4.8 g NH 3-N m -2 d -1 for storage of solid pig and poultry waste as manure heaps. Emissions for land spreading of all livestock waste were 59% of the total ammoniacal nitrogen (TAN) applied as a high dry matter content slurry and 76% of TAN applied as farm yard manure. An updated estimate of emission from UK agriculture, using updated emission factors together with 1997 statistical and census data, is presented, giving a total of 226 kt NH 3-N per year.

The impact of EU policies on energy use in and the evolution of the UK built environment

International Nuclear Information System (INIS)

Ekins, Paul; Lees, Eoin

2008-01-01

Energy use in buildings is influenced by a variety of factors in complex ways. Historically, in the UK the efficiency of energy use in buildings has not been a major consideration in their design. Now policy concern with climate change is changing this, because buildings have come to be perceived as the locus of energy use with the highest cost-effective energy savings potential. In the UK, the energy efficiency of the building stock is rather low. The paper focuses largely on energy use in the UK's existing building stock and the two main European Union Directives which affect it: the Energy Performance in Buildings Directive and the Energy Services Directive. The Directives are complex, and there are a number of supporting programmes set up by the European Commission to aid their implementation. Even so, they have been implemented in differing ways in different European countries, and implementation remains patchy. The Directives have the potential to be a major influence on the evolution of the UK's built environment, but their effect will depend on the details of the Directives' implementation and enforcement, many of which are not yet clear

The City on Screen: A Methodological Approach on Cinematic City Studies

Directory of Open Access Journals (Sweden)

Sertaç Timur Demir

2015-07-01

Full Text Available The city has a strong memory and it never forgets its own experiences. The past, the present and the future of the city can be read in its streets, buildings, sounds, myths, rhythms and stories. More importantly, if the city is portrayed through a camera, it becomes as fictional and designable as films. At this stage, there is no difference between watching a film and seeing a city. Also, cinema itself turns into a paradigm that belongs to the city. This parallelism between the city and film is like an inevitable destiny so much so that they constitute and develop each other. Accordingly, those who attempt to understand the notion of the city should consult the films made about them and vice versa; hence, this paper deals with the question of how the city is cinematized, but this question involves another question: how does the cinematic imagination fictionalize itself in the city?

Trends in vehicular emissions in China's mega cities from 1995 to 2005

International Nuclear Information System (INIS)

Wang Haikun; Fu Lixin; Zhou Yu; Du Xuan; Ge Weihua

2010-01-01

Multiyear inventories of vehicular emissions in Beijing, Shanghai and Guangzhou from 1995 through 2005 have been developed in this paper to study the vehicle emissions trends in China's mega cities during the past decade. The results show that the vehicular emissions of CO, HC, NO x and PM 10 have begun to slow their growth rates and perhaps even to decline in recent years due to the implementation of measures to control vehicular emissions in these cities. However, vehicular CO 2 emissions have substantially increased and still continue to grow due to little fuel economy improvement. Passenger cars and large vehicles (including heavy duty trucks and buses) are the major sources of vehicular CO 2 and CO emissions while large vehicles were responsible for nearly 70% and 80% of the vehicular NO x and PM 10 emissions in these mega cities. Motorcycles are also important contributors to vehicular emissions in Guangzhou and Shanghai. - The vehicular emissions (except CO 2 ) in China's mega cities have begun to slow their rates of growth and even to decline during the past decade.

'Pop-Up' Governance: developing internal governance frameworks for consortia: the example of UK10K.

Science.gov (United States)

Kaye, Jane; Muddyman, Dawn; Smee, Carol; Kennedy, Karen; Bell, Jessica

2015-01-01

Innovations in information technologies have facilitated the development of new styles of research networks and forms of governance. This is evident in genomics where increasingly, research is carried out by large, interdisciplinary consortia focussing on a specific research endeavour. The UK10K project is an example of a human genomics consortium funded to provide insights into the genomics of rare conditions, and establish a community resource from generated sequence data. To achieve its objectives according to the agreed timetable, the UK10K project established an internal governance system to expedite the research and to deal with the complex issues that arose. The project's governance structure exemplifies a new form of network governance called 'pop-up' governance. 'Pop-up' because: it was put together quickly, existed for a specific period, was designed for a specific purpose, and was dismantled easily on project completion. In this paper, we use UK10K to describe how 'pop-up' governance works on the ground and how relational, hierarchical and contractual governance mechanisms are used in this new form of network governance.

Gas prices in the UK: markets and insecurity of supply

International Nuclear Information System (INIS)

Wright, P.

2006-01-01

In this article Professor Philip Wright argues that the high and volatile gas prices experienced by UK consumers over the last 3 years are the result of the extent of liberalization in the UK which has made UK prices much more sensitive to insecurities of supply. Businesses pay the cost of this, straightaway, while the strategies which gas companies have used to respond to heightened price risks means domestic consumers also bear the cost of higher supply-markups. The prospect of high levels of demand in bad winters then just adds to price risk and its associated costs. The implication of this analysis is that it is illogical for the UK's regulator and government to blame the UK's high prices on the slow progress of liberalization in the rest of Europe - greater liberalization in Europe might simply replicate the UK's price difficulties throughout Europe.

The oxidized forms of the fragrance terpenes limonene and linalool are known to cause allergic contact dermatitis. Significant rates of contact allergy to these fragrances have been reported in European studies and in a recent worldwide study. Patch testing to oxidized terpenes is not routinely carried out either in the U.K. or in other centres internationally. To investigate the prevalence of contact allergy to oxidized limonene and linalool in the U.K. Between 1 August 2011 and 31 December 2012, 4731 consecutive patients in 13 U.K. dermatology departments were tested for hydroperoxides of limonene 0·3% pet., hydroperoxides of linalool 1·0% pet., stabilized limonene 10·0% pet. and stabilized linalool 10·0% pet. Doubtful (?+) and equivocal (±) reactions were grouped together as irritant reactions. Two hundred and thirty-seven patients (5·0%) had a positive patch test reaction to hydroperoxides of limonene 0·3% pet. and 281 (5·9%) to hydroperoxides of linalool 1·0% pet. Irritant reactions to one or both oxidized terpenes were found in 242 patients (7·3%). Eleven patients (0·2%) had a positive patch test reaction to the stabilized terpenes alone. This large, multicentre U.K. audit shows a significant rate of allergy to the hydroperoxides of limonene and linalool plus a high rate of irritant reactions. Testing to the oxidized forms alone captures the majority (97·0%; 411 of 422) of positive reactions; testing to nonoxidized terpenes appears to be less useful. We recommend that the hydroperoxides of limonene and linalool be added to an extended baseline patch test series. © 2014 British Association of Dermatologists.

Learning the law: practical proposals for UK medical education.

Science.gov (United States)

Margetts, J K

2016-02-01

Ongoing serious breaches in medical professionalism might be avoided if UK doctors rethink their approach to law. UK medical education has a role in creating a climate of change by re-examining how law is taught to medical students. Adopting a more insightful approach in the UK to the impact of The Human Rights Act and learning to manipulate legal concepts, such as conflict of interest, need to be taught to medical students now if UK doctors are to manage complex decision-making in the NHS of the future. The literature is reviewed from a unique personal perspective of a doctor and lawyer, and practical proposals for developing medical education in law in the UK are suggested.

Clark, Stephanie; Sharma, Ashish; Sisson, Scott A.

2018-03-01

In this study, information extracted from the first global urban fluvial flood risk data set (Aqueduct) is investigated and visualized to explore current and projected city-level flood impacts driven by urbanization and climate change. We use a novel adaption of the self-organizing map (SOM) method, an artificial neural network proficient at clustering, pattern extraction, and visualization of large, multi-dimensional data sets. Prevalent patterns of current relationships and anticipated changes over time in the nonlinearly-related environmental and social variables are presented, relating urban river flood impacts to socioeconomic development and changing hydrologic conditions. Comparisons are provided between 98 individual cities. Output visualizations compare baseline and changing trends of city-specific exposures of population and property to river flooding, revealing relationships between the cities based on their relative map placements. Cities experiencing high (or low) baseline flood impacts on population and/or property that are expected to improve (or worsen), as a result of anticipated climate change and development, are identified and compared. This paper condenses and conveys large amounts of information through visual communication to accelerate the understanding of relationships between local urban conditions and global processes.

CONSERVATION MANAGEMENT AND LEGISLATION THE UK EXPERIENCE

Directory of Open Access Journals (Sweden)

SIBLEY P. J.

2003-04-01

Full Text Available Underpinning the conservation management of Austropotamobius pallipes in the UK is the process of monitoring and reporting crayfish distribution. Should the current trend in the decline of A. pallipes continue, the species could be virtually extinct in mainland Britain within 30 years (SIBLEY, 2003. Conversely, if the increase in the distribution of non-indigenous crayfish species (NICS continues at its current rate, the distribution (by 10 km squares of these species could double within 15 years. These forward projections are based on a number of possibly unreliable assumptions; they illustrate however the magnitude of the challenge facing those concerned with the conservation of A. pallipes in the UK at this time. Recent work in crayfish conservation management in the UK has yielded guidance in several areas including monitoring, habitat enhancement and a re-introduction protocol for A. pallipes (KEMP and HILEY, 2003. Similarly, scientific research continues to inform our understanding of the movement and behaviour of NICS and explores new methods for the potential management of these species. In addition, the protection afforded to A. pallipes by current legislation is key to the long-term survival prospects of the species, albeit with a probable fragmented distribution, across the British Isles and continental Europe. Legal provisions in the UK derive in part from European instructions (e.g. EC Habitats and Species Directive and also from national legislation (e.g. Salmon and Freshwater Fisheries Act (1975 and the Wildlife and Countryside Act (1981. Also, a raft of “quasi-legislation” exists which requires responsible organisations in the UK to implement the white-clawed crayfish biodiversity action plan (BAP. Altogether these provisions constitute a considerable volume of legal protection for crayfish and provide the legal framework on which UK management policy and practice are based.

Tobacco imagery on prime time UK television.

2014-05-01

Smoking in films is a common and well documented cause of youth smoking experimentation and uptake and hence a significant health hazard. The extent of exposure of young people to tobacco imagery in television programming has to date been far less investigated. We have therefore measured the extent to which tobacco content occurs in prime time UK television, and estimated exposure of UK youth. The occurrence of tobacco, categorised as actual tobacco use, implied tobacco use, tobacco paraphernalia, other reference to tobacco, tobacco brand appearances or any of these, occurring in all prime time broadcasting on the five most popularly viewed UK television stations during 3 separate weeks in 2010 were measured by 1-minute interval coding. Youth exposure to tobacco content in the UK was estimated using media viewing figures. Actual tobacco use, predominantly cigarette smoking, occurred in 73 of 613 (12%) programmes, particularly in feature films and reality TV. Brand appearances were rare, occurring in only 18 programmes, of which 12 were news or other factual genres, and 6 were episodes of the same British soap opera. Tobacco occurred with similar frequency before as after 21:00, the UK watershed for programmes suitable for youth. The estimated number of incidences of exposure of the audience aged less than 18 years for any tobacco, actual tobacco use and tobacco branding were 59 million, 16 million and 3 million, respectively on average per week. Television programming is a source of significant exposure of youth to tobacco imagery, before and after the watershed. Tobacco branding is particularly common in Coronation Street, a soap opera popular among youth audiences. More stringent controls on tobacco in prime time television therefore have the potential to reduce the uptake of youth smoking in the UK.

2015-01-01

Evacuating a city is a complex problem that involves issues of governance, preparedness education, warning, information sharing, population dynamics, resilience and recovery. As natural and anthropogenic threats to cities grow, it is an increasingly pressing problem for policy makers and practitioners.   The book is the result of a unique interdisciplinary collaboration between researchers in the physical and social sciences to consider how an interdisciplinary approach can help plan for large scale evacuations.  It draws on perspectives from physics, mathematics, organisation theory, economics, sociology and education.  Importantly it goes beyond disciplinary boundaries and considers how interdisciplinary methods are necessary to approach a complex problem involving human actors and increasingly complex communications and transportation infrastructures.   Using real world case studies and modelling the book considers new approaches to evacuation dynamics.  It addresses questions of complexity, not only ...

Cancer through black eyes - The views of UK based black men towards cancer: A constructivist grounded theory study.

Mulugeta, Betselot; Williamson, Susan; Monks, Rob; Hack, Thomas; Beaver, Kinta

2017-08-01

Little is known about black African (BA) and black African-Caribbean (BAC) men's views towards cancer; yet culture and acculturation can contribute to the way in which people understand, explain and develop their attitudes towards cancer. Hence, cancer prevention and early detection strategies may not be sensitive to United Kingdom (UK)-based black men's views, affecting their awareness of risk factors and early detection services. This study explored the views of UK-based BA and BAC men towards cancer. In collaboration with black community organisations based in four major cities in the UK, 25 participants were recruited using convenience and theoretical sampling methods. Data were collected using 33 semi-structured interviews, and analysed using grounded theory analytic procedures. One core category (cancer through black eyes) and seven sub-categories emerged; 'cultural views', 'religious beliefs', 'avoiding Babylon', 'alienation', 'suspicious mind', 'advertisements and information influence very little', and 'gap in service provision (bridging the gap)'. Participants' views towards cancer were linked to socially constructed perspectives, linked with cultural and religious beliefs, and shaped by what being a black male means in society. Risk factors such as smoking and obesity had different meanings and symbolisation through black eyes. There were macro- and micro-level similarities and differences between BA and BAC men. Cancer services and related public-health campaigns aimed at black men need to understand cancer through black eyes. Public health campaigns based solely on the clinical meaning of cancer are incongruent with black men's understandings of cancer, and therefore ineffective at reducing health inequality.

2009-07-01

The large-scale and super-strength development of mineral resources in mining cities in long term has made great contributions to China's economic construction and development, but it has caused serious damage to the ecological environment even ecological imbalance at the same time because the neglect of the environmental impact even to the expense of the environment to some extent. In this study, according to the characteristics of mining cities, the scientific and practical eco-environmental vulnerability evaluation index system of mining cities had been established. Taking Panzhihua city of Sichuan province as an example, using remote sensing and GIS technology, applying various types of remote sensing image (TM, SPOT5, IKONOS) and Statistical data, the ecological environment evaluation data of mining cities was extracted effectively. For the non-linear relationship between the evaluation indexes and the degree of eco-environmental vulnerability in mining cities, this study innovative took the evaluation of eco-environmental vulnerability of the study area by using artificial neural network whose training used SCE-UA algorithm that well overcome the slow learning and difficult convergence of traditional neural network algorithm. The results of ecoenvironmental vulnerability evaluation of the study area were objective, reasonable and the credibility was high. The results showed that the area distribution of five eco-environmental vulnerability grade types was basically normal, and the overall ecological environment situation of Panzhihua city was in the middle level, the degree of eco-environmental vulnerability in the south was higher than the north, and mining activities were dominant factors to cause ecoenvironmental damage and eco-environmental Vulnerability. In this study, a comprehensive theory and technology system of regional eco-environmental vulnerability evaluation which included the establishment of eco-environmental vulnerability evaluation index

The Role of Urban Financial Centers within the Economy of Global Cities

Directory of Open Access Journals (Sweden)

Oana Mionel

2014-06-01

Full Text Available Nowadays, there is no doubt that state economy refers to city economy. In other words, the most part of a state‘s GDP is given by the urban environment, especially by capitals, which are often the economic engine of this environment. There are also cities having great economic importance abroad, beyond the state and even continental borders. These are the so-called global cities where the financial activities play an important role. There are a few cities (New York, London, Hong Kong etc. centering financial activities which are influential for large geographic areas. This research highlights the importance of the financial sector within urban economy and, subsequently, how it consolidates the status of global city. These cities are the engine of the international financial system as they host the headquarters of the most important and famous international stock exchange markets, financial supervision institutions, law firms and consulting companies.

In the United Kingdom the Central Electricity Generating Board (CEGB) are responsible for bulk supplies of electricity to the 12 Area Boards responsible for retailing in England and Wales. As such, the Board are responsible for over 90% of total generation in the UK and are therefore the body principally concerned with the financing of nuclear power growth. The author first looks at the problem of financing nuclear power from the point of view of the CEGB. Thereafter the situation in the UK is dealt with more generally and in that section reference is also made to the total call on the UK's resources involved in financing energy growth in general and nuclear power in particular.

A qualitative exploration of psychosocial specialists' experiences of providing support in UK burn care services.

Science.gov (United States)

Guest, Ella; Griffiths, Catrin; Harcourt, Diana

2018-01-01

A burn can have a significant and long-lasting psychosocial impact on a patient and their family. The National Burn Care Standards (2013) recommend psychosocial support should be available in all UK burn services; however, little is known about how it is provided. The current study aimed to explore experiences of psychosocial specialists working in UK burn care, with a focus on the challenges they experience in their role. Semi-structured telephone interviews with eight psychosocial specialists (two psychotherapists and six clinical psychologists) who worked within UK burn care explored their experiences of providing support to patients and their families. Thematic analysis revealed two main themes: burn service-related experiences and challenges reflected health professionals having little time and resources to support all patients; reduced patient attendance due to them living large distances from service; psychosocial appointments being prioritised below wound-related treatments; and difficulties detecting patient needs with current outcome measures. Therapy-related experiences and challenges outlined the sociocultural and familial factors affecting engagement with support, difficulties treating patients with pre-existing mental health conditions within the burn service and individual differences in the stage at which patients are amenable to support. Findings provide an insight into the experiences of psychosocial specialists working in UK burn care and suggest a number of ways in which psychosocial provision in the NHS burn service could be developed.

Many regions of southern UK experienced severe flooding during the 2013/2014 winter. Simultaneously, large areas in the USA and Canada were struck by prolonged cold weather. At the time, the media and public asked whether the general rainy conditions over northern Europe and the cold weather over North America were caused by climate change. Providing an answer to this question is not trivial, but recent studies show that probabilistic event attribution is feasible. Using the citizen science project weather@home, we ran over 40'000 perturbed initial condition simulations of the 2013/2014 winter. These simulations fall into two categories: one set aims at simulating the world with climate change using observed sea surface temperatures while the second set is run with sea surface temperatures corresponding to a world that might have been without climate change. The relevant modelled variables are then downscaled by a hydrological model to obtain river flows. First results show that anthropogenic climate change led to a small but significant increase in the fractional attributable risk for 30-days peak flows for the river Thames. A single number can summarize the final result from probabilistic attribution studies indicating, for example, an increase, decrease or no change to the risk of the event occurring. However, communicating this to the public, media and other scientists remains challenging. The assumptions made in the chain of models used need to be explained. In addition, extreme events, like the UK floods of the 2013/2014 winter, are usually caused by a range of factors. While heavy precipitation events can be caused by dynamic and/or thermodynamic processes, floods occur only partly as a response to heavy precipitation. Depending on the catchment, they can be largely due to soil properties and conditions of the previous months. Probabilistic attribution studies are multidisciplinary and therefore all aspects need to be communicated properly.

Full Text Available The article is based on long term field research and focuses on a community of family-related Vlax Roma from the Prešov, Sabinov and Košice regions who created a large community in Leicester, UK. The massive wave of labour migration to UK started in 2004, in the year of Slovakia’s accession to the European Union. The migration to Great Britain has been based on family networks and represents an example of chain migration based on the reciprocal help of family networks. Besides their own relatives other different non-related Roma intermediaries had an important influence on their arrival to Britain. The article focuses on the changing economic strategies of new migrants from the group in focus after their replacement to UK. In the years following Slovak accession to the EU, the prospective Romani migrants explored many illegal paths to arrive to Britain in their struggle for a better life. Approximately after a decade since their arrival, we can find this community as fully integrated into the local British working class, spending their time between my work and my house.

A tale of five cities: Using recycling frameworks to analyse inclusive recycling performance.

'Recycling' is a source of much confusion, particularly when comparing solid waste systems in high-income countries with those in low- and middle-income countries. Few analysts can explain why the performance and structure of recycling appears to be so different in rich countries from poor ones, nor why well-meaning efforts to implement recycling so often fail. The analysis of policy drivers, and the Integrated Sustainable Waste Management (ISWM) framework, come close to an explanation.This article builds on these earlier works, focusing in on five cities profiled in the 2010 UN-Habitat publication (Scheinberg A, Wilson DC and Rodic L (2010) Solid Waste Management in the World's Cities. UN-Habitat's Third Global Report on the State of Water and Sanitation in the World's Cities. Newcastle-on-Tyne, UK: Earthscan Publications). Data from these cities and others provides the basis for developing a new tool to analyse inclusive recycling performance. The points of departure are the institutional and economic relationships between the service chain, the public obligation to remove waste, pollution, and other forms of disvalue, and the value chain, a system of private enterprises trading valuable materials and providing markets for recyclables. The methodological innovation is to use flows of materials and money as indicators of institutional relationships, and is an extension of process flow diagramming.The authors are using the term 'recycling framework analysis' to describe this new form of institutional analysis. The diagrams increase our understanding of the factors that contribute to high-performance inclusive recycling. By focusing on institutional relationships, the article seeks to improve analysis, planning, and ultimately, outcomes, of recycling interventions. © The Author(s) 2015.

Full Text Available Abstract Background The UK General Medical Council has emphasized the lack of evidence on whether graduates from different UK medical schools perform differently in their clinical careers. Here we assess the performance of UK graduates who have taken MRCP(UK Part 1 and Part 2, which are multiple-choice assessments, and PACES, an assessment using real and simulated patients of clinical examination skills and communication skills, and we explore the reasons for the differences between medical schools. Method We perform a retrospective analysis of the performance of 5827 doctors graduating in UK medical schools taking the Part 1, Part 2 or PACES for the first time between 2003/2 and 2005/3, and 22453 candidates taking Part 1 from 1989/1 to 2005/3. Results Graduates of UK medical schools performed differently in the MRCP(UK examination between 2003/2 and 2005/3. Part 1 and 2 performance of Oxford, Cambridge and Newcastle-upon-Tyne graduates was significantly better than average, and the performance of Liverpool, Dundee, Belfast and Aberdeen graduates was significantly worse than average. In the PACES (clinical examination, Oxford graduates performed significantly above average, and Dundee, Liverpool and London graduates significantly below average. About 60% of medical school variance was explained by differences in pre-admission qualifications, although the remaining variance was still significant, with graduates from Leicester, Oxford, Birmingham, Newcastle-upon-Tyne and London overperforming at Part 1, and graduates from Southampton, Dundee, Aberdeen, Liverpool and Belfast underperforming relative to pre-admission qualifications. The ranking of schools at Part 1 in 2003/2 to 2005/3 correlated 0.723, 0.654, 0.618 and 0.493 with performance in 1999–2001, 1996–1998, 1993–1995 and 1989–1992, respectively. Conclusion Candidates from different UK medical schools perform differently in all three parts of the MRCP(UK examination, with the

A recent long-term demand forecast for the UK was made by Cheshire and Surrey. (SPRU Occasional Paper Series No.5, Science Policy Research Unit, Univ. Of Sussex, 1978.) Although they adopted a sectoral approach their study leaves some questions unanswered. Do they succeed in their aim of making all their assumptions fully explicit. How sensitive are their estimates to changes in assumptions and policies. Are important problems and 'turning points' fully identified in the period up to and immediately beyond their time horizon of 2000.

Mega city Mexico City is ranked the third largest urban agglomeration to date around the globe. The large extension as well as dynamic urban transformation and sprawl processes lead to a lack of up-to-date and area-wide data and information to measure, monitor, and understand the urban situation. This paper focuses on the capabilities of multisensoral remotely sensed data to provide a broad range of products derived from one scientific field - remote sensing - to support urban managing and planning. Therefore optical data sets from the Landsat and Quickbird sensors as well as radar data from the Shuttle Radar Topography Mission (SRTM) and the TerraSAR-X sensor are utilised. Using the multi-sensoral data sets the analysis are scale-dependent. On the one hand change detection on city level utilising the derived urban footprints enables to monitor and to assess spatiotemporal urban transformation, areal dimension of urban sprawl, its direction, and the built-up density distribution over time. On the other hand, structural characteristics of an urban landscape - the alignment and types of buildings, streets and open spaces - provide insight in the very detailed physical pattern of urban morphology on higher scale. The results show high accuracies of the derived multi-scale products. The multi-scale analysis allows quantifying urban processes and thus leading to an assessment and interpretation of urban trends.

Full Text Available Abstract Background Management of nightlife in UK cities focuses on creating safe places for individuals to drink. Little is known about intoxication levels as measuring total alcohol consumption on nights out is complicated by early evening interviews missing subsequent consumption and later interviews risking individuals being too drunk to recall consumption or participate at all. Here we assess mixed survey and modelling techniques as a methodological approach to examining these issues. Methods Interviews with a cross sectional sample of nightlife patrons (n = 214 recruited at different locations in three cities established alcohol consumption patterns up to the point of interview, self-assessed drunkenness and intended drinking patterns throughout the remaining night out. Researchers observed individuals' behaviours to independently assess drunkenness. Breath alcohol tests and general linear modelling were used to model blood alcohol levels at participants' expected time of leaving nightlife settings. Results At interview 49.53% of individuals regarded themselves as drunk and 79.43% intended to consume more alcohol before returning home, with around one in ten individuals (15.38% males; 4.35% females intending to consume >40 units (equal to 400 mls of pure alcohol. Self-assessed drunkenness, researcher observed measures of sobriety and blood alcohol levels all correlated well. Modelled estimates for blood alcohol at time of going home suggested that 71.68% of males would be over 0.15%BAC (gms alcohol/100 mls blood. Higher blood alcohol levels were related to drinking later into the night. Conclusions UK nightlife has used substantive health and judicial resources with the aim of creating safer and later drinking environments. Survey and modelling techniques together can help characterise the condition of drinkers when using and leaving these settings. Here such methods identified patrons as routinely getting drunk, with risks of drunkenness

The primary purposes of this study were to (i) assess levels of different types of work motivation in a sample of UK hospitality workers and make a cross-cultural comparison with Chinese counterparts and (ii) identify how work motivation and shame-based attitudes towards mental health explain the variance in mental health problems in UK hospitality workers. One hundred three UK hospitality workers completed self-report measures, and correlation and multiple regression analyses were conducted to identify significant relationships. Findings demonstrate that internal and external motivation levels were higher in UK versus Chinese hospitality workers. Furthermore, external motivation was more significantly associated with shame and mental health problems compared to internal motivation. Motivation accounted for 34-50% of mental health problems. This is the first study to explore the relationship between motivation, shame, and mental health in UK hospitality workers. Findings suggest that augmenting internal motivation may be a novel means of addressing mental health problems in this worker population.

A model assuming first-order losses by evasion and leaching was used to evaluate Hg dynamics in UK soils since 1850. Temporal deposition patterns of Hg were constructed from literature information. Inverse modelling indicated that 30% of 898 rural sites receive Hg only from the global circulation, while in 51% of cases local deposition exceeds global. Average estimated deposition is 16 μg Hg m -2 a -1 to rural soils, 19 μg Hg m -2 a -1 to rural and non-rural soils combined. UK soils currently hold 2490 tonnes of reactive Hg, of which 2140 tonnes are due to anthropogenic deposition, mostly local in origin. Topsoil currently releases 5.1 tonnes of Hg 0 per annum to the atmosphere, about 50% more than the anthropogenic flux. Sorptive retention of Hg in the lower soil exerts a strong control on surface water Hg concentrations. Following decreases in inputs, soil Hg concentrations are predicted to decline over hundreds of years. - Highlights: → Spatial data for mercury in UK soils can be related to past atmospheric deposition. → The residence time of Hg (c. 400 years) depends on gaseous evasion and leaching. → UK soils currently contribute more Hg 0 to the atmosphere than human activities. → Sorption of Hg by deeper soil is a strong control on surface water concentrations. - Atmospherically-deposited anthropogenic mercury, mostly of local origin, has accumulated in UK soils, and is now a significant source of Hg 0 to the global circulation.
