    An Empirical Analysis of Energy Demand in Namibia

    Get PDF
    Using a unique database of end-user local energy data and the recently developed Autoregressive Distributed Lag (ARDL) bounds testing approach to cointegration, we estimate the long-run elasticities of the Namibian energy demand function at both aggregated level and by type of energy (electricity, petrol and diesel) for the period 1980 to 2002. Our main results show that energy consumption responds positively to changes in GDP and negatively to changes in energy price and air temperature. The differences in price elasticities across fuels uncovered by this study have significant implications for energy taxation by Namibian policy makers. We do not find any significant cross-price elasticities between different fuel types.Energy demand; ARDL; Cointegration

    Crossroads Of Cultures: Contemporary Painting At The College Of Art, Kumasi

    Get PDF
    This project is an exploration of the preferred styles and imagery of contemporary artist and students of the College of Arts at the Kwame Nkrumah University of Science and Technology at Kumasi. What we call the \u27Arts Word\u27 of Ghana is continually renewed and shaped within the educational system, which produces its participants. In a way this is a study of academic Ghanaian arts word through the College of Arts and the individuals and arts work, which gives it life. The specific focus of my analysis is on the debate over the necessity of having African imagery or expressing African Identity in artists work; as well as the parts the religious themes play in contemporary work

    The Canons of Indian Treaty and Statutory Construction: A Proposal for Codification

    Get PDF
    This Note argues that the canons of construction should play a central role in the interpretation of Indian treaties and statutes. The Note proposes revitalization of the canons through congressional action codifying the rules of construction into federal law. Part I traces the historical development of the canons to further the federal-Indian trust relationship. Part II analyzes recent Supreme Court decisions that demonstrate decreased use of the canons. Part III argues that strong canons of construction are necessary to the development of self-determining Indian tribes and proposes federal legislation to ensure the continued vitality and importance of the canons of construction

    Circlator: automated circularization of genome assemblies using long sequencing reads

    Get PDF
    The assembly of DNA sequence data is undergoing a renaissance thanks to emerging technologies capable of producing reads tens of kilobases long. Assembling complete bacterial and small eukaryotic genomes is now possible, but the final step of circularizing sequences remains unsolved. Here we present Circlator, the first tool to automate assembly circularization and produce accurate linear representations of circular sequences. Using Pacific Biosciences and Oxford Nanopore data, Circlator correctly circularized 26 of 27 circularizable sequences, comprising 11 chromosomes and 12 plasmids from bacteria, the apicoplast and mitochondrion of Plasmodium falciparum and a human mitochondrion. Circlator is available at http://sanger-pathogens.github.io/circlator/

    ‘Framing the project’ of international human rights law: Reflections on the dysfunctional ‘family’ of the Universal Declaration

    Get PDF
    Full text embargoed until November 2013.The task of ‘framing the project’ of international human rights law is daunting to say the least. First, there is the sheer enormity and complexity of the international human rights law ‘project’: adequately mapping the subject and its key related issues is impossible in a whole book, let alone a short chapter. Secondly, it is daunting because of the sense of epistemic responsibility involved. Every framing inevitably involves selection – if not pre-selection – through the conscious (and/or unconscious) placing of focus upon features or factors considered to be significant and/or valuable. As Gitlin puts it, framing is a way of choosing, underlining and presenting ‘what exists, what happens and what matters’. In this sense, the founding document (or as Entman might put it, the inaugural ‘communicating text’) of international human rights law (the Universal Declaration of Human Rights, UDHR) functions as a particularly potent form of framing, for it selects aspects of perceived reality, making them not just salient but symbolically central to the entire philosophical, moral, juridical order designated by the term ‘international human rights law’

    The Spitzer View of Low-Metallicity Star Formation: II. Mrk 996, a Blue Compact Dwarf Galaxy with an Extremely Dense Nucleus

    Full text link
    (abridged) We present new Spitzer, UKIRT and MMT observations of the blue compact dwarf galaxy (BCD) Mrk 996, with an oxygen abundance of 12+log(O/H)=8.0. This galaxy has the peculiarity of possessing an extraordinarily dense nuclear star-forming region, with a central density of ~10^6 cm^{-3}. The nuclear region of Mrk 996 is characterized by several unusual properties: a very red color J-K = 1.8, broad and narrow emission-line components, and ionizing radiation as hard as 54.9 eV, as implied by the presence of the OIV 25.89 micron line. The nucleus is located within an exponential disk with colors consistent with a single stellar population of age >1 Gyr. The infrared morphology of Mrk 996 changes with wavelength. The IRS spectrum shows strong narrow Polycyclic Aromatic Hydrocarbon (PAH) emission, with narrow line widths and equivalent widths that are high for the metallicity of Mrk 996. Gaseous nebular fine-structure lines are also seen. A CLOUDY model requires that they originate in two distinct HII regions: a very dense HII region of radius ~580 pc with densities declining from ~10^6 at the center to a few hundreds cm^{-3} at the outer radius, where most of the optical lines arise; and a HII region with a density of ~300 cm^{-3} that is hidden in the optical but seen in the MIR. We suggest that the infrared lines arise mainly in the optically obscured HII region while they are strongly suppressed by collisional deexcitation in the optically visible one. The hard ionizing radiation needed to account for the OIV 25.89 micron line is most likely due to fast radiative shocks propagating in an interstellar medium. A hidden population of Wolf-Rayet stars of type WNE-w or a hidden AGN as sources of hard ionizing radiation are less likely possibilities.Comment: 48 pages, 13 figures, accepted for publication in the Astrophysical Journa

    Reducing maternal mortality: the contribution of the right to the highest attainable standard of health

    Over half a million women die each year due to complications during pregnancy and birth. The vast majority of these deaths are preventable. Despite longstanding international commitments to reducing maternal mortality, progress to date has been disappointing. This publication introduces the contribution of the right to the highest attainable standard of health to reducing maternal mortality

    Progression and assessment in foreign languages at Key Stage 2

    Get PDF
    The teaching of primary languages has been increasing steadily, in response to the future entitlement for all Key Stage 2 (KS2) pupils aged 7-11 to learn a foreign language by 2010. However, there remain concerns about progression both within KS2 and through to secondary school and about how learners' progress is assessed. This paper presents findings on the issues of progression and assessment taken from case studies which formed part of a project funded by the then Department for Education and Skills (DfES), now the Department for Children, Schools and Families (DCSF). This project set out to evaluate 19 local authority (LA) Pathfinders in England that were piloting the introduction of foreign language learning at KS2 between 2003 and 2005. Findings revealed that there was inconsistency between schools, even within each LA Pathfinder, in the use of schemes of work and that assessment was generally underdeveloped in the majority of the Pathfinders. In order to set these findings in context, this paper examines the issues of progression and assessment in foreign language learning in England. Finally, it investigates the challenges English primary schools face in terms of progression and assessment in the light of the new entitlement and discusses implications for the future. Managing progression, both within KS2 and through to secondary school at KS3 (ages 11-14), is one of the key factors in determining the overall success of starting languages in primary school

    Mental Disability and the Human Right to the Highest Attainable Standard of Health

    Get PDF
    In the majority of countries, the right to health of persons with mental disabilities has been grossly neglected. Necessary healthcare and support services are frequently unavailable or inaccessible, while human rights abuses are often pervasive within services where they do exist. This article explores the right to health as it relates to persons with mental disabilities. It develops an analytical framework for the right to health, derived from General Comment 14 on the right to health of the United Nations Committee on Economic, Social and Cultural Rights; and it applies this framework in the context of mental disabilities. Despite progress in developing appropriate services, additional policy and legislative initiatives are a prerequisite for the realization of the right to health for persons with mental disabilities. A human rights approach, including participation, autonomy, dignity, inclusion, monitoring, and accountability, should guide all relevant actions
