    Objective: To provide an overview of evaluating scientific scholarly impact among researchers in the health sciences. Librarians, as department liaisons, are a natural choice for guiding faculty, students, and tenure and promotion committees in understanding and responsibly applying altmetrics and bibliometrics, including the Relative Citation Ratio (RCR), to evaluate the impact of contemporary health sciences scholars. Background: Scholars in the health sciences, particularly clinician-researchers, who divide their time among patient care, education, as well as academic service, have less time for research than other scientists. Thus, citation patterns vary across the disciplines, possibly placing clinicians at a disadvantage when traditional bibliometrics are used to determine scholarly, as well as societal impact. Judicious use of altmetrics can complement bibliometrics and citation analysis to provide a clearer picture of the scholarly and societal impact of clinician-researchers. The RCR can be a helpful counterpart to altmetrics, because it normalizes across the disciplines, compensating for differences in citation patterns and is easily calculated using NIH’s iCite. Design: Discussion Paper. Data sources: Published literature in the health, information sciences, communications, and informatics disciplines. Implications for Health Sciences Librarians: Health sciences librarians can consult with faculty, students, and committees on best practices for using altmetrics to help determine scholarly impact. This paper will illustrate various means of using social media and incorporating altmetrics into clinicians’ curriculum vitae and grant proposals. It will also review the strengths, limitations and implications of using them. In addition, librarians can introduce the RCR to their departments and demonstrate iCite in calculating the RCR. Conclusion: Both altmetrics and RCR have great potential for showing a more complete and accurate picture of the scholarly and societal impact of researchers who work in the health sciences and librarians can take the lead in managing this evolution

    Formation of superconducting yttrium barium copper oxide using sulphur-containing templates

    Get PDF
    The formation of yttrium barium copper oxide (YBCO) via biotemplated routes is often plagued by unwanted stable intermediates, some of which arise from the template itself. Here we describe a method which allows sulphur-containing templates, such as proteins, to form superconducting YBCO which would have hitherto resulted in non-superconducting sulphated phases

    A new technique for elucidating β\beta-decay schemes which involve daughter nuclei with very low energy excited states

    A new technique of elucidating β\beta-decay schemes of isotopes with large density of states at low excitation energies has been developed, in which a Broad Energy Germanium (BEGe) detector is used in conjunction with coaxial hyper-pure germanium detectors. The power of this technique has been demonstrated on the example of 183Hg decay. Mass-separated samples of 183Hg were produced by a deposition of the low-energy radioactive-ion beam delivered by the ISOLDE facility at CERN. The excellent energy resolution of the BEGe detector allowed γ\gamma rays energies to be determined with a precision of a few tens of electronvolts, which was sufficient for the analysis of the Rydberg-Ritz combinations in the level scheme. The timestamped structure of the data was used for unambiguous separation of γ\gamma rays arising from the decay of 183Hg from those due to the daughter decays

    Rapid Influenza Antigen Test for Diagnosis of Pandemic (H1N1) 2009

    Get PDF
    We compared the QuickVue Influenza test with PCR for diagnosing pandemic (H1N1) 2009 in 404 persons with influenza-like illness. Overall sensitivity, specificity, and positive and negative predictive values were 66%, 84%, 84%, and 64%, respectively. Rapid test results should be interpreted cautiously when pandemic (H1N1) 2009 virus is suspected

    A psychoanalytic concept illustrated: Will, must, may, can — revisiting the survival function of primitive omnipotence

    The author explores the linear thread connecting the theory of Freud and Klein, in terms of the central significance of the duality of the life and death instinct and the capacity of the ego to tolerate contact with internal and external reality. Theoretical questions raised by later authors, informed by clinical work with children who have suffered deprivation and trauma in infancy, are then considered. Theoretical ideas are illustrated with reference to observational material of a little boy who suffered deprivation and trauma in infancy. He was first observed in the middle of his first year of life while he was living in foster care, and then later at the age of two years and three months, when he had been living with his adoptive parents for more than a year

    Production of antihydrogen at reduced magnetic field for anti-atom trapping

    Get PDF
    We have demonstrated production of antihydrogen in a 1,,T solenoidal magnetic field. This field strength is significantly smaller than that used in the first generation experiments ATHENA (3,,T) and ATRAP (5,,T). The motivation for using a smaller magnetic field is to facilitate trapping of antihydrogen atoms in a neutral atom trap surrounding the production region. We report the results of measurements with the ALPHA (Antihydrogen Laser PHysics Apparatus) device, which can capture and cool antiprotons at 3,,T, and then mix the antiprotons with positrons at 1,,T. We infer antihydrogen production from the time structure of antiproton annihilations during mixing, using mixing with heated positrons as the null experiment, as demonstrated in ATHENA. Implications for antihydrogen trapping are discussed

    Constructing female entrepreneurship policy in the UK : is the US a relevant benchmark?

    Get PDF
    Successive UK governments have introduced a range of policy initiatives designed to encourage more women to start new firms. Underpinning these policies has been an explicit ambition for the UK to achieve similar participation rates as those in the US where it is widely reported that women own nearly half the stock of businesses. The data underlying these objectives are critically evaluated and it is argued that the definitions and measures of female enterprise used in the UK and the US restrict meaningful comparisons between the two. It is suggested that the expansion of female entrepreneurship in the US is historically and culturally specific to that country. UK policy goals should reflect the national socioeconomic context, while drawing upon good practice examples from a range of other countries. The paper concludes by discussing the economic and social viability of encouraging more women in the UK to enter self-employment without fully recognising the intensely competitive sectors in which they are often located

    The Large Enriched Germanium Experiment for Neutrinoless Double Beta Decay (LEGEND)

    Get PDF
    The observation of neutrinoless double-beta decay (0νββ{\nu}{\beta}{\beta}) would show that lepton number is violated, reveal that neutrinos are Majorana particles, and provide information on neutrino mass. A discovery-capable experiment covering the inverted ordering region, with effective Majorana neutrino masses of 15 - 50 meV, will require a tonne-scale experiment with excellent energy resolution and extremely low backgrounds, at the level of \sim0.1 count /(FWHM\cdott\cdotyr) in the region of the signal. The current generation 76^{76}Ge experiments GERDA and the MAJORANA DEMONSTRATOR utilizing high purity Germanium detectors with an intrinsic energy resolution of 0.12%, have achieved the lowest backgrounds by over an order of magnitude in the 0νββ{\nu}{\beta}{\beta} signal region of all 0νββ{\nu}{\beta}{\beta} experiments. Building on this success, the LEGEND collaboration has been formed to pursue a tonne-scale 76^{76}Ge experiment. The collaboration aims to develop a phased 0νββ{\nu}{\beta}{\beta} experimental program with discovery potential at a half-life approaching or at 102810^{28} years, using existing resources as appropriate to expedite physics results.Comment: Proceedings of the MEDEX'17 meeting (Prague, May 29 - June 2, 2017
