A study of the United States coal resources
Geologically significant coal resources were identified. Statistically controlled tonnage estimates for each resource type were prepared. Particular emphasis was placed on the identification and description of coals in terms of seam thickness, inclination, depth of cover, discontinuities caused by faulting and igneous intrusion, and occurrence as isolated or multiseam deposits. The national resource was organized into six major coal provinces: the Appalachian Plateau, the Interior Basins, the Gulf Coastal Plain, the Rocky Mountain Basins, the High Plains, and North Alaska. Each basin within a province was blocked into subareas of homogeneous coal thickness. Total coal tonnage for a subarea was estimated from an analysis of the cumulative coal thickness derived from borehole or surface section records and subsequently categorized in terms of seam thickness, dip, overburden, multiseam proportions, coal quality, and tonnage impacted by severe faulting and igneous intrusions. Confidence intervals were calculated for both subarea and basin tonnage estimates
The Syntheses and Ultraviolet Absorption Spectra of 2-Imidazolines, 2-Imidazolidones and Imidazolidines
The first method used to prepare 2-imidazolines was through the reaction of aromatic aldehydes with ammonia. Amarin, which is known as 2,4,5-triphenyl-2-imidazoline, was the first compound reported to be prepared in this manner. This type of reaction has since been widely studied 2,3,4,5,6 in connection with the preparation of 2,4,5-triarylimidazolines. Furfural and ammonia have also been reported to react in a similar manner. Amarin has also been obtained from the reaction of a mixture of benzil, ammonia, and benzaldehyde
Planning, regulation and space standards in England: From 'homes for heroes' to 'Slums of the future'
The regulation of housing quality has a long history in England. As the state itself increasingly became a housing developer in the twentieth century, design standards were subject to self-regulation. Through this, the idea that housing quality includes minimum dwelling sizes - space standards - has entered public consciousness. The 2010-2015 coalition government introduced suggested space standards through planning control, but also extended the range of 'permitted development' - a form of deregulation - where space standards could not be applied. In this paper we explore the history of space standards in England and what these tell us about planning regulation
Cultural identity and ethnic newspapers in Las Vegas
Research suggests cultural identity is a fluid process characterized by individualsâ unique cultural, ethnic, and racial needs. Media are now known to reinforce ethnic group identity, language, beliefs, and customs. What are these relationships for ethnic groups living in Southern Nevada? Do media provide opportunities for cultural pluralism or for cultural assimilation? First phase results, reported last year, found ethnic radio and television in Las Vegas assimilated into larger, Anglo media business models despite programming that reinforced some aspects of ethnic cultures. This year we present second-phase results, assessing the role played by ethnic newspapers in the region. Analysis is based on qualitative interviews with Las Vegas ethnic newspaper publishers and editors
Planning Urban Manufacturing, Industrial Building Typologies, and Built Environments: Lessons From Inner London
Despite concerns about the loss of industry, industrial land, and buildings in high-value post-industrial cities, there is concurrently a renewed enthusiasm around the potential of ânewâ urban manufacturing and its contribution to the socio-economic diversity of cities. Yet, little is known about how planning policy can best support the retention and growth of urban manufacturing. To advance this agenda, this article proposes that we need a better understanding of industrial building typologies and resultant urban form. Using concepts developed by Julienne Hanson to analyse residential morphologies undergoing transformation under modernism, we apply these concepts to investigate the industrial, mixed-use contexts in two areas of London with concentrations of urban manufacturingâHackney Mare Street and Old Kent Road. The research presented examines how both areas have evolved historically to produce distinctive urban tissues and a range of industrial building typologies. The article reveals that, despite territorial similarities in the late 19th century, the mixed land uses and smaller plot sizes of Hackney Mare Street have allowed for a more resilient development pattern, whereas the greater separation of land uses, large plot sizes, and inward-facing development in the Old Kent Road has facilitated its reimagination for large-scale regeneration. We conclude that greater attention needs to be paid to the relationship between urban manufacturing and built urban form if policies that aim to protect or support the revival of manufacturing in cities are to avoid negative unintended consequences
Delivering affordable workspace: Perspectives of developers and workspace providers in London
The provision of subsidised workspace for small enterprises has been a public sector concern in many developed economies since the 1960s. In recent years, the focus of economic development initiatives has shifted away from supply side initiatives, such as fiscal incentives and the direct provision of premises, towards a consideration of the collective provision of infrastructure and services, in order to meet demands of businesses and workers in cities where there is already strong demand and growth. As well as this shift from supply- to demand-side initiatives, there has been a change in the political ideological approach to land and property development, away from public sector direct provision and funding, to place greater onus on the private sector to deliver development, infrastructure and services. The introduction of âaffordable workspaceâ planning policies by local authorities in London from the early 2000s is part of this shift â building on more established key worker and affordable housing policies.
This paper evaluates the success of affordable workspace planning policies in thirteen mixed use schemes in London, from the perspectives of developers and workspace providers, who are responsible for delivering and managing the affordable workspace. First, it finds that the perspective of the developer, in particular whether it sees affordable workspace policy as (a) an opportunity, (b) a âtoolâ to secure planning permission or (c) a burden, is mostly influenced by the way in which the affordable workspace emerged within the proposal. Developersâ perspectives and the success of their partnerships with workspace providers are critical to the successful delivery of affordable workspace within the scheme. Second, the findings show that âaffordable workspaceâ is difficult to define and deliver, with different interpretations used by delivery partners and the ability of workspace providers to deliver affordability depends critically on their organisational model. Finally, the research shows that although there are clear benefits of the policy for artists and small, creative industry businesses, it is not benefiting low-value manufacturers or small family-run retail and service businesses, nor is it generally benefiting start-ups. The implications of policy outcomes for economic development are considered; overall the beneficial impacts are limited. The research concludes that the predominant model of affordable workspace policy being promoted in London will fail to meet the aspirations of policy makers, with the limited success of policy further compounded by the global recession of the late-2000s. Alternative or complementary strategies are discussed
Documenting the âsoft spacesâ of London planning: Opportunity Areas as institutional fix in a growth-oriented city
The concentration of economic growth into large metropolises is widely documented across Europe. Yet, planning of this growth at the strategic metropolitan scale shows significant variation. This paper documents the evolution of Opportunity Areas within Greater London. Through statistical and documentary analysis, and participant observation, we reveal how they have been repurposed from a tool employed to facilitate brownfield regeneration to one that sustains growth through brokering relationships, enhancing land value and capturing it. The paper argues that the cumulative impact of these âsoft spacesâ of planning represents a fundamental change in the nature of strategic planning for city-regions
Hard, soft and thin governance spaces in land-use change: comparing office-to-residential conversions in England, Scotland and the Netherlands
In recent years, converting office buildings to residential use became a high-profile issue in the UK and in the Netherlands. There has, however, been differentiation in the policy response between England and Scotland (planning policy being devolved within the UK), and the Netherlands. We conceptualize this differentiation through the lens of variegated neoliberalism in the forms of hard, soft and thin governance spaces. England, where planning deregulation is more strongly adopted, represents a thin governance space. Scotland, where there has been little policy change, illustrates a hard governance space. The Netherlands represents a soft governance space, where proactive partnerships between government and developers predominate. This paper characterizes these distinct governance spaces and explores their impact on housing delivery and place-making, and the impact of underlying ideologies and planning culture(s) in governing office-to-residential conversions in the three countries. Drawing on national government assessments and statistics, interviews with stakeholders, and case study data from three cities: Leeds, Glasgow and Rotterdam, we conclude that while both hard and soft governance spaces, to different degrees and with different merits, are environments that enable planning, thin governance spaces â being driven more by ideology than notions of good governance â imply weak planning and place-making
Occupier responses to sustainable real estate: what's next?
Purpose â The purpose of this paper is two-fold. Primarily, it examines the relationship between sustainable buildings and occupiers, by summarising the key extant literature. Secondarily, the paper proposes avenues for future research relating to the impact of sustainability on corporate real estate strategy. Design/methodology/approach â The paper reviews over ninety relevant publications related to sustainability, real estate market responses and corporate real estate, focussing on the role and response of occupiers. The approach concentrates on occupier strategies, specifically considering influences such as corporate social responsibility (CSR), landlord tenant relationships, the changing occupier role and the âcircle of blameâ. Findings â In recent years, literature has increasingly begun to reflect nuances in occupier responses to sustainable, prime, office real estate, with some conflicting findings as to the importance of sustainability. Location remains the dominant consideration in decision making for occupiers, but sustainability is key to CSR and âvalue-addâ in certain sectors. More effective use of sustainable buildings requires improved communication between landlord and tenant. Our review demonstrates that challenges still remain in relation to the âcircle of blameâ. More research needs to be done in relation to the emergence of sustainability in the non-prime and retail sectors. Originality / value â Through collating key literature in this topical research area, the paper provides a critical review of occupier responses to sustainable real estate, and therefore a fuller understanding of emerging market practices. Additionally, it suggests future research directions. Keywords â Sustainable buildings, Occupier perceptions, CRE strategy, Decision making, Circle of blame. Paper type â Literature review
