    Building a Successful Service: Developing Open Access Funding and Advocacy at University College London

    Get PDF
    The UK Research Councils (RCUK) introduced an open access pol- icy, and accompanying funding for Article Processing Charges (APCs), in April 2013. This article describes University College London (UCL)’s experience of managing its institutional, RCUK, and Wellcome Trust open access funds, and highlights its success in exceeding the RCUK target in the first year of the policy. A large institution, processing around 1,770 APCs in 2013–2014, UCL has established a dedicated Open Access Funding Team. As well as advising authors on funders’ and publishers’ requirements, man- aging payments, and liaising with publishers, the Team delivers a comprehensive open access advocacy programme throughout the institution. Researchers who have used the Team’s services show astonishing levels of enthusiasm for open access, and for UCL’s approach to supporting them

    Practitioner review: Borderline personality disorder in adolescence: Recent conceptualization, intervention, and implications for clinical practice

    Get PDF
    The past decade has seen an unprecedented increase in research activity on personality disorders in adolescents. The increase in research activity, in addition to major nosological systems legitimizing the diagnosis of borderline personality disorder (BPD) in adolescents, highlights the need to communicate new research on adolescent personality problems to practitioners. In this review, we provide up-to-date information on the phenomenology, prevalence, associated clinical problems, etiology, and intervention for BPD in adolescents. Our aim is to provide a clinically useful practitioner review and to dispel long-held myths about the validity, diagnostic utility, and treatability of personality disorders in adolescents

    Need for artificial gravity on a manned Mars mission?

    Get PDF
    Drawing upon the extensive Soviet and Skylab medical observations, the need for artificial gravity (g) on a manned Mars mission is discussed. Little hard data derived from well done experiments exist. This dearth of information is primarily due to two factors. Inability to collect tissues from astronauts for ethical or operational reasons. Second, there was not opportunities to fly animals in space to systematically evaluate the extent of the problem, and to develop and then to prove the effectiveness of countermeasures. The Skylab and space station will provide the opportunity to study these questions and validate suggested solutions

    Can shared surfaces be safely negotiated by blind and partially sighted people?

    ‘Shared Space’ schemes are designed to remove the physical distinction between pedestrian space and traffic space in the street environment to encourage more pedestrians to use the area. They may also make it easier for people with wheelchairs, prams or similar to negotiate the space. However, by removing the kerbs, blind and partially sighted people lose one of the key references that they normally use to know they are in a safe space away from vehicles and to navigate around the area. This study is intended to understand what people with visual impairments need from a surface to make it clearly detectable, given that it should not be a barrier to progress for people with other mobility limitations. With this information, some surfaces were tested to determine their suitability as a delineator. Approach and/or Methodology An experimental approach was adopted. People with mobility impairments and blind and partially sighted people were recruited. All participants used the normal street environment unaccompanied. The blind and partially sighted participants included people who use a guide dog, those who use a long cane and those who use no assistive device. The people with mobility impairments all used some form of mobility aid for example walking stick or wheelchair. The tests were run in the pedestrian testing facility PAMELA at UCL. The top surface of the test facility was predominantly concrete paving slab, but with test surfaces discretely located. The task for all participants was to travel from one designated place in the test area to another. For some of these trials the participant would encounter one of the test surfaces, but on other trials they would not. After each trial the participants were asked to rate how easy it was to detect a change in surface, or how easy it was to pass over the surface. The different surfaces included blister paving, corduroy paving, a central delineator, slopes, roughened surfaces, and traditional kerb upstands of different heights. Results or Expected Results None of the 400mm wide surfaces was detected by all participants. Changes in level through slopes were considered both positively and negatively, some people asking for steeper gradients and some less steep. Kerb heights below 60mm were not reliably detectable by blind or partially sighted people and are an obstacle to people in wheelchairs. Further tests on more surfaces are in process and the results will be incorporated into this paper. Conclusion Early suggestions for detectable surfaces – proposed in UK schemes - have been either a barrier to people with mobility impairments, or difficult to detect for blind and partially sighted people or both. The work presented in this paper shows the difficulty in finding a suitable dual purpose surface, yet clarifies the design requirements for shared space delineators for people with mobility impairments and blind or partially sighted people. This work has reinforced the point that 400mm width is insufficient to be used as a tactile surface. Further conclusions will be made after the additional surface tests. Topic Code: Ca C.

    An assessment of twilight airglow inversion procedures using atmosphere explorer observations

    Get PDF
    The aim of this research project was to test and truth some recently developed methods for recovering thermospheric oxygen atom densities and thermospheric temperatures from ground-based observations of the 7320 A O(+)((sup 2)D - (sup 2)P) twilight air glow emission. The research plan was to use twilight observations made by the Visible Airglow Experiment (VAE) on the Atmosphere Explorer 'E' satellite as proxy ground based twilight observations. These observations were to be processed using the twilight inversion procedures, and the recovered oxygen atom densities and thermospheric temperatures were then to be examined to see how they compared with the densities and temperatures that were measured by the Open Source Mass Spectrometer and the Neutral Atmosphere Temperature Experiment on the satellite

    Self-Consistent Determination of Coupling Shifts in Broken SU(3)

    Get PDF
    The possibility that certain patterns of SU(3) symmetry breaking are dynamically enhanced in baryon-meson couplings is studied by bootstrap methods. For the strong couplings, a single dominant enhancement is found. It produces very large symmetry-breaking terms, transforming like an octet, as often conjectured. Experimental consequences are listed, such as a reduction of K-baryon couplings relative to π-baryon couplings which is in accord with the experimental weakness of K relative to π production in many circumstances, such as photoproduction and multi-BeV cosmic-ray collisions. For parity-violating nonleptonic couplings, a dominant octet enhancement is again found, as mentioned in a previous paper, which leads to an excellent fit with experiment. For parity-conserving nonleptonic couplings, on the other hand, several different enhancements compete, and the only conclusion we can draw is that terms with the "abnormal" transformation properties brought in by strong symmetry-breaking corrections are present. Our work provides a dynamical derivation of various phenomenological facts associated with SU(6), such as the dominance of the 35 representation in parity-violating nonleptonic decays

    Zooplankton Community Dynamics in the Elizabeth River, Virginia

    Get PDF
    Zooplankton community structure and dynamics were studied over a 12 month period in the Elizabeth River, an industrially polluted tidal river in the Chesapeake Bay estuarine system. An additional site in this estuary (Hampton Roads) was sampled for comparative purposes. Multivariate analysis indicated five distinct temporal groups occurred during the year, but there were no significant differences in spatial composition within the river. Maximum zooplankton concentrations were observed in July and lowest abundances were observed in February, March, and November. Copepods, especially Acartia species, were the most abundant components of the zooplankton community, comprising 67 to 93% of the total abundance. Throughout the study there were low concentrations of zooplankton across all sampling sites in the Elizabeth River. Median abundance of zooplankton during the study was 1.0 x 103 m3 compared with 7.15 x 103 m3 in Hampton Roads. Lowest concentrations were recorded in the southern branch of the Elizabeth River during the late fall and winter when numbers of 25 m were encountered. Comparisons made to other studies indicated the zooplankton density and biomass to be among the lowest recorded for the Chesapeake Bay estuarine complex
