    The use of visual and creative methods, specifically photo-elicitation in qualitative research has seen an increase in popularity in applied social science research, particularly in studies of psychology. This paper considers the evolution of the photograph as a research tool, particularly when combined with one-to-one interviewing. This paper situates the use of the photograph within historical and disciplinary contexts whilst offering new perspectives on its application to psychological fields of study. We argue that there are interesting benefits associated with supplementing qualitative methods such as one-to-one interviews with photographic stimuli. We present a recent systematic review of photo-elicitation used in research which identifies as being informed by Interpretative Phenomenological Analysis (IPA). Interpretative phenomenological Analysis is a particular qualitative approach which aims produce an account of lived experience. It is often unconcerned by adhering to the application of pre-existing theoretical preconceptions and instead offers an inductive, iterative and highly idiographic account of a phenomena of which the participant has direct experience of. This may be phenomena linked to personal changes in health and illness, or even adapting to new learning environments. Central to the purpose of IPA is the recognition that this account of lived experience is an interpretative endeavor between both participant and analyst. We argue that this need for interpretation and co-construction offers space for creative methods to ‘bridge the gap’ between simply describing a phenomena and entering into the symbolic, metaphorical interpretative world of meaning making which pushes IPA research from mediocrity to excellence. In this review we aimed to capture information related to the use of photographic methods in IPA research with particular interest in exploring the body of published work across the following protocols; 1) sample for inclusion, 2) domain of study, 3) orientation of research questions, 4) design features, 5) variation of photo-method, 6) outcomes of research and 7) critical appraisal of study. There are 14 published articles utilising photographs in IPA from 2010-2018. These studies were conducted internationally and reach across different topic domains including health, developmental, education and occupational research. The reviewed studies extend across the age span and there was notable younger age participants involved. Using photographs offered particular advantages in comparison to interview alone. These include; (a) to empower marginalized, ‘hard to reach’ groups (b) to facilitate in-depth interpretative discussions of abstract, ‘metaphorical’ concepts, sensitive issues (c) to synthesise data with other methods to strengthen and d) enhance trustworthiness of findings. There was considerable variation in how photographs were ‘produced’ ranging from photos, ‘elicited’ by participants or as a secondary artefact produced by researcher as a stimulus for discussion. Visual methods using photographs vary, and include photo-narratives, photo-journals, photo-montage, photo-questionnaires. We situation our review within fast moving changes and opportunities for this method within a wider ‘open science’ framework and also pay particular attention to exploring ethical issues to ensure confidentiality, consent, privacy and wider 2018 General Data Protection Regulation adherence

    An X-Ray Study of the Supernova Remnant G290.1-0.8

    G290.1-0.8 (MSH 11-61A) is a supernova remnant (SNR) whose X-ray morphology is centrally bright. However, unlike the class of X-ray composite SNRs whose centers are dominated by nonthermal emission, presumably driven by a central pulsar, we show that the X-ray emission from G290.1-0.8 is thermal in nature, placing the remnant in an emerging class which includes such remnants as W44, W28, 3C391, and others. The evolutionary sequence which leads to such X-ray properties is not well understood. Here we investigate two scenarios for such emission: evolution in a cloudy interstellar medium, and early-stage evolution of a remnant into the radiative phase, including the effects of thermal conduction. We construct models for these scenarios in an attempt to reproduce the observed center-filled X-ray properties of G290.1-0.8, and we derive the associated age, energy, and ambient density conditions implied by the models. We find that for reasonable values of the explosion energy, the remnant age is of order (1 - 2) x 10^{4} yr. This places a fairly strong constraint on any association between G290.1-0.8 and PSR J1105-610, which would require an anomalously large velocity for the pulsar.Comment: 7 pages, 7 figures, ApJ, accepte

    Virus taxonomy: the database of the International Committee on Taxonomy of Viruses (ICTV)

    Get PDF
    The International Committee on Taxonomy of Viruses (ICTV) is charged with the task of developing, refining, and maintaining a universal virus taxonomy. This task encompasses the classification of virus species and higher-level taxa according to the genetic and biological properties of their members; naming virus taxa; maintaining a database detailing the currently approved taxonomy; and providing the database, supporting proposals, and other virus-related information from an open-access, public web site. The ICTV web site (http://ictv.global) provides access to the current taxonomy database in online and downloadable formats, and maintains a complete history of virus taxa back to the first release in 1971. The ICTV has also published the ICTV Report on Virus Taxonomy starting in 1971. This Report provides a comprehensive description of all virus taxa covering virus structure, genome structure, biology and phylogenetics. The ninth ICTV report, published in 2012, is available as an open-access online publication from the ICTV web site. The current, 10th report (http://ictv.global/report/), is being published online, and is replacing the previous hard-copy edition with a completely open access, continuously updated publication. No other database or resource exists that provides such a comprehensive, fully annotated compendium of information on virus taxa and taxonomy

    Achievement goals, self-handicapping, and performance: A 2 × 2 achievement goal perspective

    Elliot and colleagues (2006) examined the effects of experimentally induced achievement goals, proposed by the trichotomous model, on self-handicapping and performance in physical education. Our study replicated and extended the work of Elliot et al. by experimentally promoting all four goals proposed by the 262 model (Elliot & McGregor, 2001), measuring the participants’ own situational achievement goals, using a relatively novel task, and testing the participants in a group setting. We used a randomized experimental design with four conditions that aimed to induce one of the four goals advanced by the 262 model. The participants (n¼138) were undergraduates who engaged in a dart-throwing task. The results pertaining to self-handicapping partly replicated Elliot and colleagues’ findings by showing that experimentally promoted performance-avoidance goals resulted in less practice. In contrast, the promotion of mastery-avoidance goals did not result in less practice compared with either of the approach goals. Dart-throwing performance did not differ among the four goal conditions. Personal achievement goals did not moderate the effects of experimentally induced goals on selfhandicapping and performance. The extent to which mastery-avoidance goals are maladaptive is discussed, as well as the interplay between personal and experimentally induced goals

    Road and bridge construction across gypsum karst in England

    Gypsum karst problems in the Permian and Triassic sequences of England have caused difficult conditions for bridge and road construction. In Northern England, the Ripon Bypass crosses Permian strata affected by active gypsum karst and severe subsidence problems. Here, the initial borehole site investigation for the road was supplemented by resistivity tomography studies. The roadway was reinforced with two layers of tensile membrane material within the earth embankment. This will prevent dangerous catastrophic collapse, but will allow sagging to show where problems exist. The River Ure Bridge was constructed across an area of subsidence pipes filled with alluvial deposits. It was built with extra strength, larger than normal foundations. If one pier fails, the bridge is designed for adjacent arches to span the gap without collapse. The bridge piers are also fitted with electronic load monitoring to warn of failure. In the Midlands area of England, road construction over Triassic gypsum has required a phase of ground improvement on the Derby Southern Bypass. Here, the gypsum caps a hill where it was formerly mined; it dips through a karstic dissolution zone into an area of complete dissolution and collapse. The road and an associated flyover were built across these ground conditions. A major grouting program before the earthworks began treated the cavities in the mine workings and the cavernous margin of the gypsum mass. Within the karstic dissolution zone, gypsum blocks and cavities along the route were identified by conductivity and resistivity geophysical surveys, excavated and backfilled. In the areas of complete dissolution and collapse, the road foundation was strengthened with vibrated stone columns and a reinforced concrete road deck was used

    The Impact of Heatwaves on Community Morbidity and Healthcare Usage: A Retrospective Observational Study Using Real-Time Syndromic Surveillance.

    We investigated the impact of a moderate heatwave on a range of presenting morbidities in England. Asthma, difficulty breathing, cerebrovascular accident, and cardiovascular symptoms were analysed using general practitioner in hours (GPIH), out of hours (GPOOH) and emergency department (ED) syndromic surveillance systems. Data were stratified by age group and compared between a heatwave year (2013) and non-heatwave years (2012, 2014). Incidence rate ratios were calculated to estimate the differential impact of heatwave compared to non-heatwave summers: there were no apparent differences for the morbidities tested between the 2013 heatwave and non-heatwave years. A subset of GPIH data were used to study individuals at higher risk from heatwaves based on their pre-existing disease. Higher risk patients were not more likely to present at GPs or ED than other individuals. Comparing GPIH consultations and ED attendances for myocardial infarction/ischaemia (MI), there was evidence of a fall in the presentation of MI during the heatwave, which was particularly noted in the 65-74 years age group (and over 75 years in ED attendances). These results indicate the difficulty in identifying individuals at risk from non-fatal health effects of heatwaves and hot weather

    Reimagining the River: An Outdoor Vision of the Anthropocene and the White River through the Lens of Place

    Get PDF
    poster abstractIn 2016, the International Union of Geological Sciences will decide whether or not human impact on the Earth constitutes a new geologic epoch – the Anthropocene. If agreed upon, this epoch will acknowledge the effects human agency has upon the stratigraphic record, and the implications of a human-driven world. Reimagining the River takes the global Anthropocene to the City of Indianapolis by creating an outdoor museum of the White River. This museum exhibit will display the past, present, and future of the White River, showcasing the historical narrative of the human-river relationship. Exploring the Anthropocene through the story of the White River will engage the citizens of Indianapolis to develop a sense of ownership for the intertwined state of the River and Indianapolis. The intention of this engagement is to build a community that reimagines what the river was, is, and can become. Reimagining the River will be located on the White River State Park Bridge, and will feature audiovisual elements that relate current scenes surrounding the River to the past. Historical photographs complemented with a brief historical narrative will be juxtaposed with the areas surrounding the installation, framing Indianapolis’ urban environment as the exhibit. The installation will be accessible to all demographics, including children and individuals with disability. The exhibit will also include resources to encourage further audience participation, including podcasts, geocaching, and a website. Ongoing research pathways will be created to encourage the tracking and measurement of audience engagement and understanding of how human agency has affected the White River, its tributaries, and the City of Indianapolis
