    Drones surround us. They are in the Middle East, assisting the United States military in carrying out its missions. They are around our businesses, used by professional photographers, farmers, insurance adjusters, and countless other professionals in a growing number of commercial applications. With the sales of drones expected to skyrocket over the next several years, the state of Mississippi should enact regulations in order to restrict and take advantage of their use

    Recommendations concerning energy information model documentation, public access, and evaluation

    In this study we provide an analysis of the factors underlying Congressional concern regarding model documentation, policies for public access, and evaluation procedures of the Energy Information Administration (EIA) and its predecessor agencies; we also develop and present recommendations designed to improve current practice. This study reviews the history of Congressional concern; surveys current EIA organization and policies; provides an analysis of the model evaluation process; and presents recommendations to improve organizational efficiency and responsiveness, the model documentation process, public access policies, and model evaluation

    Analysis quality report on the EIA Annual Report to Congress 1978, volume III : coal supply

    Get PDF
    The Energy Information Administration (EIA) is charged by Congress to prepare an Annual Report to Congress (ARC) which includes projections of energy supplies, consumption and prices, as well as the relation of energy to other economic activity. As an aid to users of ARC, the EIA Office of Analysis Oversight and Access (OAOA) is preparing "Analysis Quality Reports" on particular components of the energy information analysis system used in developing the ARC-78 projections. This report focuses on the Coal Supply Module used for the midterm projections of the ARC-78. The Coal Supply Module is part of the EIA's National Coal Model. The review and analysis presented here is based upon the MIT Energy Model Analysis Program's (EMAP) evaluation of the documentation and implementation of the Coal Supply Module sponsored by OAOA, and an indepth evaluation of a related model--the ICF Coal and Electric Utilities Model--which also employs the EIA Coal Supply Module. The indepth evaluation has been sponsored by the Electric Power Research Institute

    Time-resolved, multi-color photometry and spectroscopy of Virgo 4 (OU Vir): a high orbital inclination, short orbital period dwarf nova

    Full text link
    We present multi-color photometry and time resolved spectroscopy of OU Vir. The analysis of the quiescent light curve shows that OU Vir is characterized by i) strong cycle-to-cycle brightness variations, and ii) hot spot modulated light curve with grazing eclipse of the impact region. Colors are derived both in- and out- of eclipse. The time-resolved spectroscopy allows us to produce the radial velocity curve from the Hα\alpha accretion disk emission line which possibly reveals only weak evidence for hot spot line emission. The hot spot is believed to be a turbulent optically thick region, producing mostly continuum emission.Comment: 8 pages (including figures), 7 figures. To Be published in A&

    Compassionate containment? Balancing technical safety and therapy in the design of psychiatric wards

    Get PDF
    This paper contributes to the international literature examining design of inpatient settings for mental health care. Theoretically, it elaborates the connections between conceptual frameworks from different strands of literature relating to therapeutic landscapes, social control and the social construction of risk. It does so through a discussion of the substantive example of research to evaluate the design of a purpose built inpatient psychiatric health care facility, opened in 2010 as part of the National Health Service (NHS) in England. Findings are reported from interviews or discussion groups with staff, patients and their family and friends. This paper demonstrates a strong, and often critical awareness among members of staff and other participants about how responsibilities for risk governance of ‘persons’ are exercised through ‘technical safety’ measures and the implications for therapeutic settings. Our participants often emphasised how responsibility for technical safety was being invested in the physical infrastructure of certain ‘places’ within the hospital where risks are seen to be ‘located’. This illuminates how the spatial dimensions of social constructions of risk are incorporated into understandings about therapeutic landscapes. There were also more subtle implications, partly relating to ‘Panopticist’ theories about how the institution uses technical safety to supervise its own mechanisms, through the observation of staff behaviour as well as patients and visitors. Furthermore, staff seemed to feel that in relying on technical safety measures they were, to a degree, divesting themselves of human responsibility for risks they are required to manage. However, their critical assessment showed their concerns about how this might conflict with a more therapeutic approach and they contemplated ways that they might be able to engage more effectively with patients without the imposition of technical safety measures. These findings advance our thinking about the construction of therapeutic landscapes in theory and in practice

    High spectral resolution time-resolved optical spectroscopy of V893 Sco

    Get PDF
    We present high resolution time-resolved optical spectra of the high inclination short orbital period dwarf nova V893 Sco. We performed spectral analysis through radial velocity measurements, Doppler mapping, and ratioed Doppler maps. Our results indicate that V893 Sco's accretion disk is dissimilar to WZ Sge's accretion disk, and does not fit any of the current accretion disk models. We derive the system parameters M1 and i, and present evidence for V893 Sco as a very young cataclysmic variable and an ER UMa star. We advance the hypothesis that all ER UMa stars may be newly formed cataclysmic variables.Comment: 23 pages (total), 8 figures, accepted by Ap

    How does a transforming landscape influence bird breeding success?

    Get PDF
    Context The conversion of agricultural landscapes to tree plantations is a major form of landscape transformation worldwide, but its effects on biodiversity, particularly key population processes like reproductive success, are poorly understood. Objectives We compared bird breeding success between woodland remnants surrounded by maturing stands of plantation Radiata Pine and a matched set of woodland remnants in semi-cleared grazing land. Methods Our study was conducted in the Nanangroe region in south-eastern New South Wales, Australia. Using repeated field measurements, we quantified bird breeding success in 23 woodland remnants; 13 surrounded by Radiata Pine plantations and 10 on farms where remnants were surrounded by semi-cleared grazing land. We matched the attributes of native remnant patches between two types of matrix. Results We found that: (1) rates of nesting success of smaller-bodied birds in woodland remnants surrounded by grazing land were significantly higher than in woodland remnants surrounded by pine plantations; and (2) taxa with domed nests were more successful at nesting than species that constructed open cup/bowl nests in woodland remnants within farmlands. Conclusions Our findings suggest that bird breeding success in remnant woodland patches is significantly diminished as a result of the conversion of semi-cleared grazing land to pine plantations
