    Back to the Future: How UK-based news organisations are rediscovering objectivity

    The emergence of 'fake news' during the tumultuous Brexit referendum and Trump election campaign has sent news organisations scurrying to set up special teams of journalists to debunk deliberately misleading stories and verify facts. This paper examines the steps being taken to counter the spate of false news stories being spread through social media and asks whether normative values of objectivity are about to enjoy a comeback. Typical markers of objectivity such as freedom from bias, detachment and fact-based reporting date back to the late 19th Century and, despite being deeply ingrained in the Anglo-American news culture, have always been subject to criticism and challenge. Most recently, the growth of openly partisan or populist media has illustrated a deep distrust in traditional news outlets and is overtly questioning whether it is time to jettison objectivity. The increasing use of emotive (and often unfiltered) user-generated content and the rise in citizen journalism appear to have undermined the concept even further. But are we now experiencing a backlash? Through a series of interviews with editorial policy makers at major UK and US news organisations, the paper explores how fake news and other concerns around the impact of social media are leading to fresh debate about objectivity and its potential to make quality journalism stand out

    Participatory politics, environmental journalism and newspaper campaigns

    This is an Author's Accepted Manuscript of an article published in Journalism Studies, 13(2), 210 - 225, 2012, copyright Taylor & Francis, available online at: http://www.tandfonline.com/10.1080/1461670X.2011.646398.This article explores the extent to which approaches to participatory politics might offer a more useful alternative to understanding the role of environmental journalism in a society where the old certainties have collapsed, only to be replaced by acute uncertainty. This uncertainty not only generates acute public anxiety about risks, it has also undermined confidence in the validity of long-standing premises about the ideal role of the media in society and journalistic professionalism. The consequence, this article argues, is that aspirations of objective reportage are outdated and ill-equipped to deal with many of the new risk stories environmental journalism covers. It is not a redrawing of boundaries that is needed but a wholesale relocation of our frameworks into approaches better suited to the socio-political conditions and uncertainties of late modernity. The exploration of participatory approaches is an attempt to suggest one way this might be done

    Three-Dimensional Structure of the Enveloped Bacteriophage Φ12: An Incomplete T = 13 Lattice Is Superposed on an Enclosed T = 1 Shell

    BACKGROUND:Bacteriophage phi12 is a member of the Cystoviridae, a unique group of lipid containing membrane enveloped bacteriophages that infect the bacterial plant pathogen Pseudomonas syringae pv. phaseolicola. The genomes of the virus species contain three double-stranded (dsRNA) segments, and the virus capsid itself is organized in multiple protein shells. The segmented dsRNA genome, the multi-layered arrangement of the capsid and the overall viral replication scheme make the Cystoviridae similar to the Reoviridae. METHODOLOGY/PRINCIPAL FINDINGS:We present structural studies of cystovirus phi12 obtained using cryo-electron microscopy and image processing techniques. We have collected images of isolated phi12 virions and generated reconstructions of both the entire particles and the polymerase complex (PC). We find that in the nucleocapsid (NC), the phi12 P8 protein is organized on an incomplete T = 13 icosahedral lattice where the symmetry axes of the T = 13 layer and the enclosed T = 1 layer of the PC superpose. This is the same general protein-component organization found in phi6 NC's but the detailed structure of the entire phi12 P8 layer is distinct from that found in the best classified cystovirus species phi6. In the reconstruction of the NC, the P8 layer includes protein density surrounding the hexamers of P4 that sit at the 5-fold vertices of the icosahedral lattice. We believe these novel features correspond to dimers of protein P7. CONCLUSIONS/SIGNIFICANCE:In conclusion, we have determined that the phi12 NC surface is composed of an incomplete T = 13 P8 layer forming a net-like configuration. The significance of this finding in regard to cystovirus assembly is that vacancies in the lattice could have the potential to accommodate additional viral proteins that are required for RNA packaging and synthesis

    Evolution of Mutational Robustness in an RNA Virus

    Mutational (genetic) robustness is phenotypic constancy in the face of mutational changes to the genome. Robustness is critical to the understanding of evolution because phenotypically expressed genetic variation is the fuel of natural selection. Nonetheless, the evidence for adaptive evolution of mutational robustness in biological populations is controversial. Robustness should be selectively favored when mutation rates are high, a common feature of RNA viruses. However, selection for robustness may be relaxed under virus co-infection because complementation between virus genotypes can buffer mutational effects. We therefore hypothesized that selection for genetic robustness in viruses will be weakened with increasing frequency of co-infection. To test this idea, we used populations of RNA phage φ6 that were experimentally evolved at low and high levels of co-infection and subjected lineages of these viruses to mutation accumulation through population bottlenecking. The data demonstrate that viruses evolved under high co-infection show relatively greater mean magnitude and variance in the fitness changes generated by addition of random mutations, confirming our hypothesis that they experience weakened selection for robustness. Our study further suggests that co-infection of host cells may be advantageous to RNA viruses only in the short term. In addition, we observed higher mutation frequencies in the more robust viruses, indicating that evolution of robustness might foster less-accurate genome replication in RNA viruses

    Plate tectonics of virus shell assembly and reorganization in phage φ8, a distant relative of mammalian reoviruses

    Get PDF
    The hallmark of a virus is its capsid, which harbors the viral genome and is formed from protein subunits, which assemble following precise geometric rules. dsRNA viruses use an unusual protein multiplicity (120 copies) to form their closed capsids. We have determined the atomic structure of the capsid protein (P1) from the dsRNA cystovirus Φ8. In the crystal P1 forms pentamers, very similar in shape to facets of empty procapsids, suggesting an unexpected assembly pathway that proceeds via a pentameric intermediate. Unlike the elongated proteins used by dsRNA mammalian reoviruses, P1 has a compact trapezoid-like shape and a distinct arrangement in the shell, with two near-identical conformers in nonequivalent structural environments. Nevertheless, structural similarity with the analogous protein from the mammalian viruses suggests a common ancestor. The unusual shape of the molecule may facilitate dramatic capsid expansion during phage maturation, allowing P1 to switch interaction interfaces to provide capsid plasticity

    Stabbing News: Articulating Crime Statistics in the Newsroom

    Get PDF
    There is a comprehensive body of scholarly work regarding the way media represent crime and how it is constructed in the media narrative as a news item. These works have often suggested that in many cases public anxieties in relation to crime levels are not justified by actual data. However, few works have examined the gathering and dissemination of crime statistics by non-specialist journalists and the way crime statistics are gathered and used in the newsroom. This article seeks to explore in a comparative manner how journalists in newsrooms access and interpret quantitative data when producing stories related to crime. In so doing, the article highlights the problems and limitations of journalists in dealing with crime statistics as a news source, while assessing statistics-related methodologies and skills used in the newsrooms across the United Kingdom when producing stories related to urban crime

    At a rate never before seen in American history, young adults are abandoning traditional news media. Tuned Out: Why Americans Under 40 Don't Follow the News examines the reasons behind this problem and its consequences for American society. Author David T. Z.
