    Acknowledgments The seismic interpretation and image processing was carried out in the SeisLab facility at the University of Aberdeen (sponsored by BG BP and Chevron). Seismic imaging analysis was performed using GeoTeric (ffA), and analysis of seismic amplitudes was performed in Petrel 2015 (Schlumberger). We would like to thank the NDDC (RG11766-10) for funding this research and Statoil for the release of the Sleipner field seismic dataset utilized in this research paper and also Anne-Kari Furre and her colleagues for their assistance. We also thank the editor, Alejandro Escalona and the two anonymous reviewers for their constructive and in depth comments that improved the paper.Peer reviewedPostprin

    Trade, Foreign Investment, and Industrial Policy

    Get PDF
    During the last three decades, developing countries have made enormous strides in opening up their protected domestic markets to international trade and foreign investment. Yet most countries have not simply opened up their markets. They have also instituted a range of policies to encourage exports, attract foreign direct investment(FDI), promote innovation, and favor some industries over others. This leads to the following question: is openness to trade and FDI alone sufficient to achieve high growth rates in developing countries? If harnessing the gains from globalization requires additional policies, can we identify them? While some types of complementary policies, such as building roads and ports, are not controversial, others are. Bhagwati's suggestion to "attract foreign funds" implies tilting incentives in favor of foreign investors, which means abandoning policy neutrality. Our goal in this chapter is to explore the popular but controversial idea that developing countries benefit from abandoning policy neutrality vis-a-vis trade, FDI and resource allocation across industries.Trade, Foreign Investment, Industrial Policy, Developing Countries

    The cervical cancer epidemic that screening has prevented in the UK.

    No full text
    BACKGROUND: Recent reports suggest that the reduction in mortality achieved by the UK national cervical screening programme is too small to justify its financial and psychosocial costs, except perhaps in a few high-risk women. METHODS: We analysed trends in mortality before 1988, when the British national screening programme was launched, to estimate what future trends in cervical cancer mortality would have been without any screening. FINDINGS: Cervical cancer mortality in England and Wales in women younger than 35 years rose three-fold from 1967 to 1987. By 1988, incidence in this age-range was among the highest in the world despite substantial opportunistic screening. Since national screening was started in 1988, this rising trend has been reversed. INTERPRETATION: Cervical screening has prevented an epidemic that would have killed about one in 65 of all British women born since 1950 and culminated in about 6000 deaths per year in this country. However, these estimates are subject to substantial uncertainty, particularly in relation to the effects of oral contraceptives and changes in sexual behaviour. 80% or more of these deaths (up to 5000 deaths per year) are likely to be prevented by screening, which means that about 100000 (one in 80) of the 8 million British women born between 1951 and 1970 will be saved from premature death by the cervical screening programme at a cost per life saved of about pound 36000. The birth cohort trends also provide strong evidence that the death rate throughout life is substantially lower in women who were first screened when they were younger

    Measuring social desirability amongst men with intellectual disabilities: The psychometric properties of the Self- and Other-Deception Questionnaire—Intellectual Disabilities

    Get PDF
    Background Social desirability has been construed as either inaccurately attributing positive characteristics to oneself (self-deception), or inaccurately denying that one possesses undesirable characteristics to others (other-deception or impression management). These conceptualisations of social desirability have not been considered in relation to people with intellectual disabilities (IDs), but they are important constructs to consider when undertaking a psychological assessment of an individual, especially within forensic contexts. Therefore, we revised two existing measures of self- and other-deception and considered their psychometric properties. Methods Thirty-two men with mild IDs and 28 men without IDs completed the Self- and Other-Deception Questionnaires—Intellectual Disabilities (SDQ-ID and ODQ-ID) on two occasions, two weeks apart. Results Men with IDs scored significantly higher on the SDQ-ID and the ODQ-ID than men without IDs. However, these differences disappeared when Full Scale IQ, Verbal IQ and Performance IQ were controlled in relation to the SDQ-ID, and partially disappeared in relation to the ODQ-ID. The SDQ-ID and the ODQ-ID had substantial internal consistency in relation to men with IDs (k = 0.82 and 0.84 respectively). The test-retest reliability of the SDQ-ID was good (ri = 0.68), while the test-retest reliability of the ODQ-ID was moderate (ri = 0.56), for men with IDs. The SDQ-ID had moderate (k = 0.60) and the ODQ-ID had substantial (k = 0.70) internal consistency in relation to men without IDs, while the test-retest reliability of the SDQ-ID was excellent (ri = 0.87) as was the case for the ODQ-ID (ri = 0.85). Conclusions The SDQ-ID and the ODQ-ID have satisfactory psychometric properties in relation to men with and without IDs. Future research using these instruments is propose

    THE IMPACT OF GOVERNMENT POLICIES ON AGRICULTURAL PRODUCTIVITY AND STRUCTURE: PRELIMINARY RESULTS

    Get PDF
    Our paper begins with a consideration of the causal relationships among productivity, farm structure, government farm payments and public investments in research and extension. We then empirically test key relationships for a relatively recent period (1960-96) in the history of agricultural structural adjustment using a simultaneous equations econometric model. Future work will expand and refine the measurement of variables thought to explain the relationship between productivity and structure.Agricultural and Food Policy, Productivity Analysis,

    The public health importance of scabies in community domiciliary care settings: an exploratory cross-sectional survey of health protection teams in England

    Get PDF
    Scabies is a contagious skin infection commonly occurring in institutions such as care homes. However, a large proportion of vulnerable people in England receive domiciliary care in the community and their experience of scabies has not been described. We undertook a pragmatic cross-sectional survey of Health Protection Teams (HPTs) in England to determine the burden of scabies related to domiciliary care. Fifteen cases or outbreaks were notified to HPTs between January 2013 and December 2017. Although a relatively uncommon event for individual HPTs, they were complex to manage and required the co-ordination of multiple stakeholders. Diagnosis was often delayed and required several clinical consultations. A lack of guidance led to difficulties establishing stakeholder roles and responsibilities and sources of funding for treatment. The stigmatisation of scabies sometimes affected the quality of care provided to patients, such as use of excessive personal protective equipment. Our study demonstrates that scabies is an issue of public health importance for domiciliary care service providers and users, and research is required to better understand the impacts of the disease and to develop evidence-based guidance. More generally, there is a need for simpler treatment regimens and methods of diagnosing scabies
