    Environmental Indicator Report: Species and Habitats

    Get PDF
    During the fall and winter of 2001-2002, the New Hampshire Estuaries Project’s Technical Advisory Committee (TAC) developed a suite of environmental indicators to track progress toward the NHEP’s management goals and objectives. These indicators were fully described in terms of their performance criteria, statistical methods, and measurable goals in the NHEP’s Monitoring Plan, which was most recently updated in March 2003 (NHEP, 2003). The next step is to use these indicators to produce an updated “State of the Estuaries” report by mid-2003. The TAC decided to break this task into three sections: shellfish indicators in the fall of 2002; water quality indicators in the winter of 2002-2003; and land use/habitat indicators in the spring of 2003. For each group of indicators, the NHEP Coastal Scientist would prepare an “Indicator Report” that summarizes the available information and results of statistical tests for each of the indicators. The TAC would review and comment on this report, and then recommend a subset of the most important or illustrative indicators to be presented to the Management Committee. Finally, after being presented to both the TAC and the Management Committee, the indicator charts and interpretation would be incorporated in the State of the Estuaries report. This report is the last of four indicator reports to be presented to the TAC. The focus of this report is the NHEP’s species and habitats indicators (see list below). In an effort to be brief, the details of the monitoring programs for each indicator are not included. Please refer to the NHEP Monitoring Plan (NHEP, 2003) for additional details for each indicator

    Linear Statistics of Non-Hermitian Matrices Matching the Real or Complex Ginibre Ensemble to Four Moments

    We prove that, for general test functions, the limiting behavior of the linear statistic of an independent entry random matrix is determined only by the first four moments of the entry distributions. This immediately generalizes the known central limit theorem for independent entry matrices with complex normal entries. We also establish two central limit theorems for matrices with real normal entries, considering separately functions supported exclusively on and exclusively away from the real line. In contrast to previously obtained results in this area, we do not impose analyticity on test functions.Comment: Preliminary versio

    Wilmington gray to blue

    Get PDF
    Wilmington is situated on the divide of two major watersheds, the Cape Fear River and the Atlantic Intracoastal Waterway. All surface waters in Wilmington drain to one of these two water bodies and are divided into two groups: tidal creeks and Cape Fear River tributaries. Cape Fear River tributaries drain directly to the Cape Fear River and comprise the western portion of Wilmington’s surface waters. Tidal creeks drain directly into the Atlantic Intracoastal Waterway and make up the eastern portion of Wilmington’s surface waters. (PDF contains 4 pages

    Questionnaires in clinical trials: guidelines for optimal design and administration.

    Get PDF
    A good questionnaire design for a clinical trial will minimise bias and maximise precision in the estimates of treatment effect within budget. Attempts to collect more data than will be analysed may risk reducing recruitment (reducing power) and increasing losses to follow-up (possibly introducing bias). The mode of administration can also impact on the cost, quality and completeness of data collected. There is good evidence for design features that improve data completeness but further research is required to evaluate strategies in clinical trials. Theory-based guidelines for style, appearance, and layout of self-administered questionnaires have been proposed but require evaluation

    New Hampshire Estuaries Probabilistic Monitoring Program in 2008

    Get PDF
    The New Hampshire Department of Environmental Services (NHDES), the U.S. Environmental Protection Agency (EPA) and the University of New Hampshire (UNH) partnered in 2008 to implement the National Coastal Assessment in NH’s estuarine waters. USEPA provided the study design and field protocols. UNH collected the samples and field data at the designated sites in the estuary. Funding for this sampling effort was provided by the Piscataqua Region Estuaries Partnership, NHDES, and the New Hampshire Coastal Program. The purpose of this memo is to document the quality assurance checks that were performed by NHDES. The data were not collected as part of a national survey; therefore, the data have not been transmitted to USEPA
