    A radio continuum survey of the southern sky at 1420 MHz. Observations and data reduction

    Get PDF
    We describe the equipment, observational method and reduction procedure of an absolutely calibrated radio continuum survey of the South Celestial Hemisphere at a frequency of 1420 MHz. These observations cover the area 0h < R.A. < 24h for declinations less than -10 degree. The sensitivity is about 50 mK T_B (full beam brightness) and the angular resolution (HPBW) is 35.4', which matches the existing northern sky survey at the same frequency.Comment: 9 pages with 9 figures, A&A, in pres

    “This Wonderful Machine”: How Should We Teach Humanities Texts like Gulliver’s Travels in the Time of ChatGPT?

    The quoted phrase in the essay title comes from a passage in Jonathan Swift\u27s Gulliver’s Travels in which a Grand Academy of Lagado professor demonstrates a “wonderful Machine” that can generate scores of books “without the least Assistance from Genius or Study.” The essay explore the challenge for teaching classic humanities texts like Gulliver that the (perhaps not so) “wonderful Machine” called ChatGPT poses. Student Owen Terry’s Chronicle essay (May 12, 2023) identifies two crucial aspects of that challenge: “We don’t fully lean into AI and teach how to best use it, and we don’t fully prohibit it to keep it from interfering with exercises in critical thinking.” The essay explains my rationale not to “lean into AI but to prohibit it and to promote instead “critical thinking

    Multiple social identities enhance health post-retirement because they are a basis for giving social support

    This is the final version of the article. Available from the publisher via the DOI in this record.We examine the extent to which multiple social identities are associated with enhanced health and well-being in retirement because they provide a basis for giving and receiving social support. Results from a cross-sectional study show that retirees (N = 171) who had multiple social identities following (but not prior to) retirement report being (a) more satisfied with retirement, (b) in better health, and (c) more satisfied with life in general. Furthermore, mediation analyses revealed an indirect path from multiple social identities to greater satisfaction with retirement and better health through greater provision, but not receipt, of social support to others. These findings are the first to point to the value of multiple group membership post-retirement as a basis for increased opportunities to give meaningful support to others. We discuss the theoretical and practical implications for the management of multiple identities in the process of significant life transitions such as retirement.This work was supported by three grants from the Australian Research Council awarded to JJ (FT110100238), CH (DP160102514), and AH (FL110100199

    Social group memberships in retirement are associated with reduced risk of premature death: evidence from a longitudinal cohort study.

    This is the final version of the article. Available from [publisher] via the DOI in this record.OBJECTIVES: Retirement constitutes a major life transition that poses significant challenges to health, with many retirees experiencing a precipitous decline in health status following retirement. We examine the extent to which membership in social groups following retirement determines quality of life and mortality. DESIGN: The longitudinal impact of the number of social group memberships before and after the transition to retirement was assessed on retirees' quality of life and risk of death 6 years later. SETTING: Nationally representative cohort study of older adults living in England. PARTICIPANTS: Adults who underwent the transition to retirement (N=424). A matched control group (N=424) of participants who had comparable demographic and health characteristics at baseline but did not undergo the transition to retirement were also examined. OUTCOME MEASURES: Analyses examined participants' quality of life and mortality during a period of 6 years. RESULTS: Retirees who had two group memberships prior to retirement had a 2% risk of death in the first 6 years of retirement if they maintained membership in two groups, a 5% risk if they lost one group and a 12% risk if they lost both groups. Furthermore, for every group membership that participants lost in the year following retirement, their experienced quality of life 6 years later was approximately 10% lower. These relationships are robust when controlling for key sociodemographic variables (age, gender, relationship status and socioeconomic status prior to retirement). A comparison with a matched control group confirmed that these effects were specific to those undergoing the transition to retirement. The effect of social group memberships on mortality was comparable to that of physical exercise. CONCLUSIONS: Theoretical implications for our understanding of the determinants of retiree quality of life and health, and practical implications for the support of people transitioning from a life of work to retirement are discussed.This research was supported by two grants from the Australian Research Council awarded to JJ (FT110100238) and SAH (FL110100199).

    The On The Fly Imaging Technique

    Full text link
    The On-The-Fly (OTF) imaging technique enables single-dish radio telescopes to construct images of small areas of the sky with greater efficiency and accuracy. This paper describes the practical application of the OTF imaging technique. By way of example the implementation of the OTF imaging technique at the NRAO 12 Meter Telescope is described. Specific requirements for data sampling, image formation, and Doppler correction are discussed.Comment: 10 pages, 13 figures, accepted A&

    The Temperature of the Cosmic Microwave Background

    The FIRAS data are independently recalibrated using the WMAP data to obtain a CMB temperature of 2.7260 +/- 0.0013. Measurements of the temperature of the cosmic microwave background are reviewed. The determination from the measurements from the literature is cosmic microwave background temperature of 2.72548 +/- 0.00057 K.Comment: 6 Pages 3 figure

    Real Estate Investment Trusts (REITS) : A new business model in the FTSE100

    Get PDF
    CC-BY-NC-NDThis paper is about the Real Estate Investment Trust (REIT) business model. REITs benefit from tax concessions and Fair Value Accounting (FVA) practices. REITs distributing over 90 percent of profits can obtain tax concessions for their shareholders. This encourages profit distribution at the expense of accumulating retained earnings in shareholder equity. The financial viability of REITs depends upon FVA because this records holding gains when property values are increased. These holding gains can be employed to generate additional financial leverage. However, REITs are exposed to property market volatility and this can quickly undermine solvency, credit ratings and financial stability.Peer reviewedFinal Accepted Versio
