    Although developments in the sell-side analyst literature have revealed the role of intellectual capital (IC) in analysts’ work, the whole information intermediation progress of IC remains a “black box”. This paper develops an analyst information intermediation model, illustrating how ‘soft’ information changes through analyst acquisition, processing and disclosure of information. Bourdieu’s ideas of habitus, field and capital are used to develop our explanation of the analyst information intermediation model. We argue that the combination of empirical evidence and theoretical explanation provides a new and more comprehensive way to improve understanding of the role of analysts within knowledge and social contexts

    SARS-CoV-2 immunochromatographic IgM/IgG rapid test in pregnancy: A false friend?

    Background: An increasing body of evidence has revealed that SARS-CoV-2 infection in pregnant women could increase the risk of adverse maternal and fetal outcomes. Careful monitoring of pregnancies with COVID-19 and measures to prevent neonatal infection are warranted. Therefore, rapid antibody tests have been suggested as an efficient screening tool during pregnancy. Cases: We analysed the clinical performance during pregnancy of a rapid, lateral-flow immunochromatographic assay for qualitative detection of SARS-CoV-2 IgG/IgM antibodies. We performed a universal screening including 169 patients during their last trimester of pregnancy. We present a series of 14 patients with positive SARS-CoV-2 immunochromatographic assay rapid test result. Immunochromatographic assay results were always confirmed by chemiluminescent microparticle immunoassays for quantitative detection of SARS-CoV-2 IgG and IgM+IgA antibodies as the gold standard. We observed a positive predictive value of 50% and a false positive rate of 50% in pregnant women, involving a significantly lower diagnostic performance than reported in non-pregnant patients. Discussion: Our data suggest that although immunochromatographic assay rapid tests may be a fast and profitable screening tool for SARS-CoV-2 infection, they may have a high false positive rate and low positive predictive value in pregnant women. Therefore, immunochromatographic assay for qualitative detection of SARS-CoV-2 IgG/IgM antibodies must be verified by other test in pregnant patients

    Reciprocity as a foundation of financial economics

    This paper argues that the subsistence of the fundamental theorem of contemporary financial mathematics is the ethical concept ‘reciprocity’. The argument is based on identifying an equivalence between the contemporary, and ostensibly ‘value neutral’, Fundamental Theory of Asset Pricing with theories of mathematical probability that emerged in the seventeenth century in the context of the ethical assessment of commercial contracts in a framework of Aristotelian ethics. This observation, the main claim of the paper, is justified on the basis of results from the Ultimatum Game and is analysed within a framework of Pragmatic philosophy. The analysis leads to the explanatory hypothesis that markets are centres of communicative action with reciprocity as a rule of discourse. The purpose of the paper is to reorientate financial economics to emphasise the objectives of cooperation and social cohesion and to this end, we offer specific policy advice

    Projects of devotion : energy exploration and moral ambition in the cosmoeconomy of oil and gas in the Western United States

    This project has received funding from the European Research Council (ERC) under the European Union's Horizon 2020 research and innovation programme under grant agreement No 715146. The authors also acknowledge the funding received to carry out this research from the Leverhulme Trust (ECF‐2013‐177) and the British Academy (EN150010).This article considers how people working in the oil and gas industry in Colorado perceive their involvement in energy exploration in relation to broader understandings of devotion, compassion, and outreach. I argue that although their energy projects may appear to merely echo companies’ formal promotional pitches, the oil field and corporate actors’ own moral ambitions reveal more-than-human cosmoeconomic visions of oil’s potentiality. This article thus demonstrates how multiple and diverging ethical registers intersect and inform the valuation of oil.Publisher PDFPeer reviewe
