    The Water Resources Division, U.S. Geological Survey, is charged with (1) maintaining a hydrologic network in Nevada that provides information on the status of the State\u27s water resources and (2) engaging in technical water-resources investigations that have a high degree of transferability. To meet these broad objections, 26 projects were active in Nevada during fiscal year 1982 in cooperation with 36 Federal, State, and local agencies. Total funds were 3,319,455,ofwhichStateandlocalcooperativefundingamountedto3,319,455, of which State and local cooperative funding amounted to 741,500 and Federal funding (comprised of Geological Survey Federal and cooperative programs plus funds from six other Federal agencies) amounted to $2,577,955 for the fiscal year.Projects other than continuing programs for collection of hydrologic data included the following topics of study: geothermal resources, areal ground-water resources and ground-water modeling, waste disposal, prehistoric hydrology, acid mine drainage, the unsaturated zone, stream and reservoir sedimentation, river-quality modeling, flood hazards, and remote sensing in hydrology. For each project, the objectives, approach, progress in fiscal year 1982, and plans for fiscal year 1983 are described herein. A total of 26 reports and symposium abstracts were published or in press during fiscal year 1982 as an outgrowth of project work in the State

    Cognitive behavioral therapy (CBT) interventions -- particularly stimulus control and sleep hygiene -- are well-validated, effective treatments for chronic insomnia that are equivalent or superior to pharmacological interventions (strength of recommendation: A, based on systematic reviews). The long-term efficacy of CBT interventions, and their successful implementation by primary care physician (as compared with behavioral science providers), is unclear

    Shifting Rurality American Gothic, Iowa Nice, Biotech and Political Expectations in Rural America

    This paper traces the linkage between heritage landscape within the context of the election of Donal Trump. Trump\u27s invocations of heritage riled certain regions of the US which had a distinct connection to Regionalism, both as a political idea and as an aesthetic practice. Focusing on Iowa, home to the quintessential American painting, American Gothic, the paper looks at modernity and agriculture, and how the two categories seem to rely on (but also negate) heritage. By examining what a genetically modified landscape might mean in relation to the historical image of the pastoral/provincial farmer, a network of frictions and tensions emerge. These building dichotomies have both emancipatory and hegemonic potentials especially with the enmeshment of all things in global scale capitalism

    Academic Diversity: Reading Instruction for Students with Special Needs

    Get PDF
    Provisions to assure that all children are provided quality reading instruction have always been a concern for classroom teachers. Today, greater sensitivity to learners with special needs has led to their inclusion in regular classrooms for the full instructional day. Implications for the reading instructional program are clear; it must employ a variety of instructional and organizational techniques to suit a wide range of student abilities. This article addresses legislation that led to the present focus on classroom inclusion for students with special needs and accommodation of the students with special needs in the classroom reading program. Particular discussion is focused on children who are diagnosed with attention-deficit hyperactivity disorder (ADHD) and children identified as intellectually gifted. Specific recommendations and examples are given that will help these children reach their full academic potential and allow them to experience success in a regular classroom reading program

    Large-Scale Atomistic Simulations of Environmental Effects on the Formation and Properties of Molecular Junctions

    Full text link
    Using an updated simulation tool, we examine molecular junctions comprised of benzene-1,4-dithiolate bonded between gold nanotips, focusing on the importance of environmental factors and inter-electrode distance on the formation and structure of bridged molecules. We investigate the complex relationship between monolayer density and tip separation, finding that the formation of multi-molecule junctions is favored at low monolayer density, while single-molecule junctions are favored at high density. We demonstrate that tip geometry and monolayer interactions, two factors that are often neglected in simulation, affect the bonding geometry and tilt angle of bridged molecules. We further show that the structures of bridged molecules at 298 and 77 K are similar.Comment: To appear in ACS Nano, 30 pages, 5 figure

    Revising the WHO verbal autopsy instrument to facilitate routine cause-of-death monitoring.

    OBJECTIVE: Verbal autopsy (VA) is a systematic approach for determining causes of death (CoD) in populations without routine medical certification. It has mainly been used in research contexts and involved relatively lengthy interviews. Our objective here is to describe the process used to shorten, simplify, and standardise the VA process to make it feasible for application on a larger scale such as in routine civil registration and vital statistics (CRVS) systems. METHODS: A literature review of existing VA instruments was undertaken. The World Health Organization (WHO) then facilitated an international consultation process to review experiences with existing VA instruments, including those from WHO, the Demographic Evaluation of Populations and their Health in Developing Countries (INDEPTH) Network, InterVA, and the Population Health Metrics Research Consortium (PHMRC). In an expert meeting, consideration was given to formulating a workable VA CoD list [with mapping to the International Classification of Diseases and Related Health Problems, Tenth Revision (ICD-10) CoD] and to the viability and utility of existing VA interview questions, with a view to undertaking systematic simplification. FINDINGS: A revised VA CoD list was compiled enabling mapping of all ICD-10 CoD onto 62 VA cause categories, chosen on the grounds of public health significance as well as potential for ascertainment from VA. A set of 221 indicators for inclusion in the revised VA instrument was developed on the basis of accumulated experience, with appropriate skip patterns for various population sub-groups. The duration of a VA interview was reduced by about 40% with this new approach. CONCLUSIONS: The revised VA instrument resulting from this consultation process is presented here as a means of making it available for widespread use and evaluation. It is envisaged that this will be used in conjunction with automated models for assigning CoD from VA data, rather than involving physicians

    Jupiter’s auroras during the Juno approach phase as observed by the Hubble Space Telescope

    We present movies of the Hubble Space Telescope (HST) observations of Jupiter’s FUV auroras observed during the Juno approach phase and first capture orbit, and compare with Juno observations of the interplanetary medium near Jupiter and inside the magnetosphere. Jupiter’s FUV auroras indicate the nature of the dynamic processes occurring in Jupiter’s magnetosphere, and the approach phase provided a unique opportunity to obtain a full set of interplanetary data near to Jupiter at the time of a program of HST observations, along with the first simultaneous with Juno observations inside the magnetosphere. The overall goal was to determine the nature of the solar wind effect on Jupiter’s magnetosphere. HST observations were obtained with typically 1 orbit per day over three intervals: 16 May – 7 June, 22-30 June and 11-18 July, i.e. while Juno was in the solar wind, around the bow shock and magnetosphere crossings, and in the mid-latitude middle-outer magnetospheres. We show that these intervals are characterised by particularly dynamic polar auroras, and significant variations in the auroral power output caused by e.g. dawn storms, intense main emission and poleward forms. We compare the variation of these features with Juno observations of interplanetary compression regions and the magnetospheric environment during the intervals of these observations

    Structured decision making as a conceptual framework to identify thresholds for conservation and management

    Thresholds and their relevance to conservation have become a major topic of discussion in the ecological literature. Unfortunately, in many cases the lack of a clear conceptual framework for thinking about thresholds may have led to confusion in attempts to apply the concept of thresholds to conservation decisions. Here, we advocate a framework for thinking about thresholds in terms of a structured decision making process. The purpose of this framework is to promote a logical and transparent process for making informed decisions for conservation. Specification of such a framework leads naturally to consideration of definitions and roles of different kinds of thresholds in the process. We distinguish among three categories of thresholds. Ecological thresholds are values of system state variables at which small changes bring about substantial changes in system dynamics. Utility thresholds are components of management objectives (determined by human values) and are values of state or performance variables at which small changes yield substantial changes in the value of the management outcome. Decision thresholds are values of system state variables at which small changes prompt changing in management actions in order to reach specified management objectives. The approach that we present focuses directly on the objectives of management, with an aim to providing decisions that are optimal with respect to those objectives. This approach clearly distinguishes the components of he decision process that are inherently subjective (management objectives, potential management actions) from those that are more objective (systems models, estimates of system state). Optimization based on these components then leads to decision matrices specifying optimal actions to be taken at various values of system state variables. Values of state variables separating different actions in such matrices are viewed as decision thresholds. Utility thresholds are included in the objectives component, and ecological thresholds may be embedded in models projecting consequences of management actions. Decision thresholds are determined by the above-listed components of a structured decision process. These components may themselves vary over time, inducing variation in the decision threshold inherited from them. These dynamic decision thresholds can then be determined using adaptive management. We provide numerical examples (that are based on patch occupancy models) of structures decision process that include all three kinds of thresholds

    Navigating the Looking Glass:Severing the Lawyer's Head in <i>Arkham Asylum</i>

    Get PDF
    Reading Arkham Asylum jurisprudentially, we encounter a story of the meeting of reason and unreason in the context of justice – of conscious law and its unconscious threat. Batman’s exploration of the Asylum is symbolic of the legal unconscious, and reflects the processes of repression that can be seen in dominant legal knowledge. A threat to this dominant knowledge can be seen in Two-Face’s reliance on his coin to ‘judge’ his victims. Moreover, Arkham Asylum configures the threat of law’s unconscious as the lawyer’s severed head inside the house of law. Ultimately, Batman’s journey through Arkham Asylum reminds law of the aesthetic and irrational contexts that it strives to deny and from which it seeks to defend itself – and that cultural legal studies explores. It recalls the unreason outside law’s logic, the chaos outside its order, the madness outside its sanity. The lesson of Batman’s encounters in the Asylum is that we should remember the ‘madness’ outside the legal order, and thus recognise that law is always already more than its conscious ‘sanity’ can contain
