A descriptive analysis of the drinking behaviour of the 1958 cohort at age 33 and the 1970 cohort at age 34

This paper provides a comparison of the drinking patterns of members of the 1958 British Birth Cohort at age 33 in 1991 and members of the 1970 British Birth Cohort at age 34 in 2004. In particular the focus is on the relationships between social class, gender and drinking behaviour and how these may have changed over time. In addition we exploit the detailed information available in the cohort studies about the kinds of alcohol that individuals drink to provide a description of how this varies between the two cohorts born twelve years apart. The paper also provides detailed descriptive analyses of the links between frequency of drinking and the number of units drunk for both cohorts. Results suggest that although the 1970 cohort report drinking more frequently than the 1958 cohort did at a similar age, there is only a modest increase in the average number of units of alcohol consumed per week for women and no increase for men. The paper also highlights some possible problems with data on alcohol consumption collected in the 2000 sweep of NCDS and BCS70 and concludes by making some comparisons between data collected in the cohort studies and data collected in the General Household Survey

Evaluation of Interplanetary Magnetic Field Tracing Models Using Impulsive SEPs

Current Interplanetary Magnetic Field (IMF) models are evaluated in this study to determine which model(s) perform an accurate representation of this magnetic structure. These IMF models include the Parker Spiral model, the Potential Field Source Surface (PFSS) model, the Wang-Sheeley-Arge (WSA) model and the ENLIL model. Impulsive Solar Energetic Particles (SEPs) are used as tracers to determine the magnetic structure of the IMF and provide source locations for model comparisons. Each individual model is analyzed, compared to the identified solar source region and a longitude/latitude offset of these traces assigned. The model connection of the PFSS and Parker models is found to provide the lowest latitude and longitude offsets from the identified source regions with RMS values of 21.9 and 18.5 respectfully. Model discrepancies are investigated and suggestions are made to improve model tracing performance

Nucleus accumbens activation mediates the influence of reward cues on financial risk-taking

In functional magnetic resonance imaging (FMRI) research, nucleus accumbens (NAcc) activation spontaneously increases prior to financial risk taking. Since anticipation of diverse rewards can increase NAcc activation, even incidental reward cues may influence financial risk-taking. Using event-related FMRI, we predicted and found that anticipation of viewing rewarding stimuli (erotic pictures for 15 heterosexual males) increased financial risk taking, and that this effect was partially mediated by increases in NAcc activation. These results are consistent with the notion that incidental reward cues influence financial risk taking by altering anticipatory affect, and so identify a neuropsychological mechanism that may underlie effective emotional appeals in financial, marketing, and political domains.neuroeconomics, neurofinance, brain, financial risk taking, risk preferences, decision making, nucleus accumbens, striatum, reward cues, FMRI, brain imaging

Speckle interferometry at SOAR in 2019

The results of speckle interferometric observations at the 4.1 m Southern Astrophysical Research Telescope (SOAR) in 2019 are given, totaling 2555 measurements of 1972 resolved pairs with separations from 15 mas (median 0.21") and magnitude difference up to 6 mag, and non-resolutions of 684 targets. We resolved for the first time 90 new pairs or subsystems in known binaries. This work continues our long-term speckle program. Its main goal is to monitor orbital motion of close binaries, including members of high-order hierarchies and Hipparcos pairs in the solar neighborhood. We give a list of 127 orbits computed using our latest measurements. Their quality varies from excellent (25 orbits of grades 1 and 2) to provisional (47 orbits of grades 4 and 5).Comment: Accepted by The Astronomical Journal. 10 pages, 5 Figures. Measurements and non-resolutions, published electronically, are available from the first author. arXiv admin note: substantial text overlap with arXiv:1905.1043
