  1. A financial option perspective on energy security and strategic storage

    Haar, Lawrence; Haar, Laura
    There are many approaches to measuring energy security: some researchers use geologic and technical factors while others focus upon supply and demand. Common to these approaches is the emphasis upon exposure to supply disruption but not to the probability of its occurrence. As petroleum markets have shown themselves resilient to secular events, we ask if an alternative approach might be useful in quantifying energy security. We apply financial option theory to five eventful periods to learn the expectations of market participants to disruptions. We find the forward-looking views of petroleum market participants to be robust and accurate with regard to...

  2. Optimising OPEC strategy: a financial option approach

    Haar, Lawrence; Haar, Laura
    ABSTRACT The article examines the use of discretionary production by key OPEC members to protect the long-term value of their reserves. Interpretations vary on the behaviour and market power of OPEC. The Organisation sees its role as protecting the security of supply, stabilising markets and ensuring a fair return upon capital. Given challenges facing OPEC, there are diverse views on how it should respond, including the role of swing producers in protecting market share and stabilizing prices. Using option theory, it is argued that the market stabilisation policy of OPEC provides free risk management to the global market. Abandoning this policy,...

  3. The compatibility of renewable energy with liberalized electricity markets: a retrospective on British policy between 2010 and 2016

    Haar, Lawrence; Haar, Laura N.
    Soon after the UK’s Feed-in Tariff (FIT) scheme supporting renewable energy was introduced, in 2010, adjustments and modifications were made to eligibility criteria and incentive prices. Prices paid for renewable energy (RE) were cut, deployment caps and preliminary accreditation were introduced and efficiency standards for solar PV were imposed. Controversy ensued as supporters sought help for the nascent RE technologies whilst detractors claimed the scheme was wasteful. We examine how RE was supported and its wider impact upon various stakeholder in order to consider its compatibility with the UK’s liberalised electricity markets. We employ a financial performance metric to measure...

  5. Urban crime in Nigeria: trends, costs and policy considerations

    Ojo, Adegbola; Ojewale, Oluwole
    For more than two decades, calls have been made for inter-city comparative analysis of crime in Nigeria. Whilst selected single-city studies have been conducted, there is no recent robust attempt to systematically gauge the internal crime dynamics of cities in Nigeria against each other. This research monograph represents a bold empirical move in this regard. Thirty six Nigerian cities are placed on a rigorous and reliable comparative footing by applying selected statistical measures from a battery of indicators. The extensive numerical analysis is further supplemented by interpretivist approaches which help to yield fresh contextual evidence about the dynamics of crimes...

This report is particularly focused on providing intellectual access to blind and partially sighted visitors.

  7. An evaluation of heating strategy, thermal environment and carbon emissions in three UK churches

    Pretlove, Stephen
    Church buildings are an important part of our cultural heritage and their preservation is critical. Many are in poor condition, and now provide community activities in addition to religious worship. This requires reconsideration of environmental needs, and upgrading of services to provide efficient, comfortable and healthy conditions. Churches contain many culturally valuable artefacts and materials that are sensitive to the environment, yet have survived for centuries in their natural environment. Most churches in the UK have had heating installed, causing damage as a result of fluctuating conditions during intermittent occupancy. This study evaluates the optimum environmental needs for comfort and conservation and...

  9. Evolutionary history of Leishmania killicki (synonymous Leishmania tropica) and taxonomic implications

    Chaara, Dhekra; Ravel, Christophe; BaÑuls, Anne- Laure; Haouas, Najoua; Lami, Patrick; Talignani, Loïc; El baidouri, Fouad; Jaouadi, Kaouther; Harrat, Zoubir; Dedet, Jean-Pierre; Babba, Hamouda; Pratlong, Francine
    Background: Leishmania (L.) killicki is responsible for the chronic cutaneous leishmaniasis. The taxonomic status of this parasite is still not well defined. It was suggested on one hand to include this taxon within L. tropica complex but also on the other hand to consider it as a distinct phylogenetic complex. The present work represents the more detailed study on the evolutionary history of L. killicki relative to L. tropica and the taxonomic implications. Methods: Thirty five L. killicki and 25 L. tropica strains isolated from humans and from several countries were characterized using the MultiLocus Enzyme Electrophoresis (MLEE) and the MultiLocus Sequence Typing (MLST) approaches. Results: The genetic...

  11. Festival Space: gender, liminality and the carnivalesque

    Pielichaty, Hanya
    Purpose - Contemporary outdoor rock and popular music festivals offer liminal spaces in which event participants can experience characteristics associated with the carnivalesque. Festival goers celebrate with abandonment, excess and enjoy a break from the mundane routine of everyday life. The aim of this conceptual paper is to explore the way gender is negotiated in the festival space. Design/methodology/approach - The rock and popular music tribute festival, known as ‘Glastonbudget’ provides the focus for this conceptual paper. A pilot ethnographic study at the event utilising photographic imagery was used to understand the way in which gender is displayed. Findings - It...

  12. Open Education and the emancipation of academic labour

    Winn, Joss
    I have previously argued that open education is a liberal project with a focus on the freedom of things rather than the freedom of people (Winn, Joss. 2012. “Open Education: From the Freedom of Things to the Freedom of People.” In Towards Teaching in Public: Reshaping the Modern University, edited by Michael Neary, Howard Stevenson, and Les Bell, 133– 147. London: Continuum). Furthermore, I have argued that despite an implicit critique of private property with its emphasis on ‘the commons’, the literature on open education offers no corresponding critique of academic labour (Neary, Mike, and Joss Winn. 2012. “Open Education: Common(s),...

  14. The co-operative university: Labour, property and pedagogy

    Winn, Joss
    I begin this article by discussing the recent work of academics and activists to identify the advantages and issues relating to co-operative forms of higher education, and then focus on the ‘worker co-operative’ organisational form and its applicability and suitability to the governance of and practices within higher educational institutions. Finally, I align the values and principles of worker co-ops with the critical pedagogic framework of ‘Student as Producer’. Throughout I employ the work of Karl Marx to theorise the role of labour and property in a ‘co-operative university’, drawing particularly on later Marxist writers who argue that Marx’s labour theory of...

  16. Writing about academic labour

    Winn, Joss
    This essay calls for a return to the labour theory of Marx, or rather to Marx’s negative critique of labour and its “pivotal” role in comprehending the political economy of higher education. It argues that a critique of capitalism and its apparent complexity must be undertaken through an immanent critique of labour, rather than from the standpoint of labour as has been the case in both Marxist and non-Marxist traditions of labour studies. Through a review of exemplar articles on ‘academic labour’, the essay draws attention to the fundamental importance of employing Marx’s method of abstraction so as to understand...

  18. Where is creativity?: A multi-disciplinary approach

    Shorthose, Jim; Maycroft, Neil
    Where is Creativity? A Multi-disciplinary Approach goes beyond the orthodox image of creativity as laying inside the brain-mind, to explore how and why it also emerges from relationships between people, from physical spaces such as workplaces and cities, as a result of new media technology and the Web, and due to the effects of broad contexts of the economy and industry. It explores contemporary psychological, sociological, anthropological, economic and philosophical debates concerning creativity in an accessible way, which non-specialist and creative practitioners can appreciate, culminating in a picture of the anatomy of creativity which seeks to provide a concrete guide...
