    Finite-Larmor-radius equilibrium and currents of the Earth’s flank magnetopause

    No full text
    We consider the one-dimensional equilibrium problem of a shear-flow boundary layer within an ‘extended-fluid model’ of a plasma that includes the Hall and the electron pressure terms in Ohm’s law, as well as dynamic equations for anisotropic pressure for each species and first-order finite-Larmor-radius (FLR) corrections to the ion dynamics. We provide a generalized version of the analytic expressions for the equilibrium configuration given in Cerri et al., (Phys. Plasmas, vol. 20 (11), 2013, 112112), highlighting their intrinsic asymmetry due to the relative orientation of the magnetic field B, b = B/|B| , and the fluid vorticity w = curl(u) (‘ wb asymmetry’). Finally, we show that FLR effects can modify the Chapman–Ferraro current layer at the flank magnetopause in a way that is consistent with the observed structure reported by Haaland et al., (J. Geophys. Res. (Space Phys.), vol. 119, 2014, pp. 9019–9037). In particular, we are able to qualitatively reproduce the following key features: (i) the dusk–dawn asymmetry of the current layer, (ii) a double-peak feature in the current profiles and (iii) adjacent current sheets having thicknesses of several ion Larmor radii and with different current directions

    Social desirability and sustainable food research: A systematic literature review

    No full text
    Social desirability bias could affect the results of research using self-reports, like questionnaires, which are the dominant approach to explore sustainable food consumption and its drivers. Despite various methodological and statistical approaches have been suggested to counteract social desirability, their use in research about sustainable food has not been systematically reviewed before. Therefore, a systematic literature review was carried out covering 388 peer-reviewed studies. The number of papers mentioning social desirability bias steadily increased since the 1990s. However, our results indicates that the overall proportion of relevant papers discussing it is low, with most of those doing so giving no clear indication about its causes and/or consequences for data quality. Moreover, few studies provide information about the data collection process, despite well-known situational factors influencing social desirability bias. A few papers implemented methodological remedies, like anonymity or proper scaling. Statistical remedies, like social desirability scales, were found in two studies only. Our findings suggest three major improvements in survey research about sustainable food. First, a better description of the data collection process is recommended, to better identify the limitations and strengths of a specific study. Second, procedural remedies against social desirability, which are now the gold standard in other survey-based disciplines, should be used more consistently. Finally, more research is needed adopting social desirability scales, which are relatively common in other fields of research using surveys (e.g. dietary studies), as well as specialized questioning techniques for sensitive answers

    In this latest Advance & Rutgers Report, entitled “A Tripartite Post-Recession Rebalancing,” Dean James W. Hughes and Professor Joseph J. Seneca deliver an incisive assessment of the current market conditions and obstacles in the path of our economic recovery. They offer a statistical cautionary tale that the private and public sector need to hear and acknowledge in order for the economy to make continued progress.This report was published as Issue Paper Number 7, November 2011, in Advance & Rutgers Report
