Less Agricultural Phosphorus Applied in 2019 Led to Less Dissolved Phosphorus Transported to Lake Erie.

Extreme precipitation events affect water quantity and quality in various regions of the world. Heavy precipitation in 2019 resulted in a record high area of unplanted agricultural fields in the U.S.

Privacy-Preserving Linkage of Genomic and Clinical Data Sets.

The capacity to link records associated with the same individual across data sets is a key challenge for data-driven research. The challenge is exacerbated by the potential inclusion of both genomic and clinical data in data sets that may span multiple legal jurisdictions, and by the need to enable re-identification in limited circumstances. Privacy-Preserving Record Linkage (PPRL) methods address these challenges.

Vertical Stratification of Soil Phosphorus as a Concern for Dissolved Phosphorus Runoff in the Lake Erie Basin.

During the re-eutrophication of Lake Erie, dissolved reactive phosphorus (DRP) loading and concentrations to the lake have nearly doubled, while particulate phosphorus (PP) has remained relatively constant. One potential cause of increased DRP concentrations is P stratification, or the buildup of soil-test P (STP) in the upper soil layer (<5 cm). Stratification often accompanies no-till and mulch-till practices that reduce erosion and PP loading, practices that have been widely implemented throughout the Lake Erie Basin.

Global solutions to regional problems: Collecting global expertise to address the problem of harmful cyanobacterial blooms. A Lake Erie case study.

In early August 2014, the municipality of Toledo, OH (USA) issued a 'do not drink' advisory on their water supply directly affecting over 400,000 residential customers and hundreds of businesses (Wilson, 2014). This order was attributable to levels of microcystin, a potent liver toxin, which rose to 2.5μgL in finished drinking water.

Governance Through Privacy, Fairness, and Respect for Individuals.

Introduction: Individuals have a moral claim to be involved in the governance of their personal data. Individuals' rights include privacy, autonomy, and the ability to choose for themselves how they want to manage risk, consistent with their own personal values and life situations. The Fair Information Practices principles (FIPPs) offer a framework for governance.

John A. Popplestone (1928-2013).

Try as we might, few of us are able to leave a lasting legacy to psychology. John A. Popplestone, who was born in Louisville, Kentucky, on October 30, 1928 and died September 15, 2013, in Akron, Ohio, is someone who did just that.

Evaluating and classifying the readiness of technology specifications for national standardization.

The American Recovery and Reinvestment Act (ARRA) of 2009 clearly articulated the central role that health information technology (HIT) standards would play in improving healthcare quality, safety, and efficiency through the meaningful use of certified, standards based, electronic health record (EHR) technology. In 2012, the Office of the National Coordinator (ONC) asked the Nationwide Health Information Network (NwHIN) Power Team of the Health Information Technology Standards Committee (HITSC) to develop comprehensive, objective, and, to the extent practical, quantitative criteria for evaluating technical standards and implementation specifications and classifying their readiness for national adoption. The Power Team defined criteria, attributes, and metrics for evaluating and classifying technical standards and specifications as 'emerging,' 'pilot,' or 'ready for national standardization' based on their maturity and adoptability.

Total synthesis of the antitumor antibiotic (±)-streptonigrin: first- and second-generation routes for de novo pyridine formation using ring-closing metathesis.

The total synthesis of (±)-streptonigrin, a potent tetracyclic aminoquinoline-5,8-dione antitumor antibiotic that reached phase II clinical trials in the 1970s, is described. Two routes to construct a key pentasubstituted pyridine fragment are depicted, both relying on ring-closing metathesis but differing in the substitution and complexity of the precursor to cyclization. Both routes are short and high yielding, with the second-generation approach ultimately furnishing (±)-streptonigrin in 14 linear steps and 11% overall yield from inexpensive ethyl glyoxalate.

Exploring occupational and health behavioral causes of firefighter obesity: a qualitative study.

Background: Firefighters, as an occupational group, have one of the highest prevalence rates of obesity. A qualitative study investigated occupational and health behavioral determinants of obesity among firefighters.

Methods: Four focus groups were conducted with firefighters of every rank as Phase I of the FORWARD study which was designed to assess health behavioral and occupational characteristics related to obesity in firefighters.

Interannual variability of cyanobacterial blooms in Lake Erie.

After a 20-year absence, severe cyanobacterial blooms have returned to Lake Erie in the last decade, in spite of negligible change in the annual load of total phosphorus (TP). Medium-spectral Resolution Imaging Spectrometer (MERIS) imagery was used to quantify intensity of the cyanobacterial bloom for each year from 2002 to 2011. The blooms peaked in August or later, yet correlate to discharge (Q) and TP loads only for March through June.

Synthesis of 2,4,6-trisubstituted pyridines via an olefin cross-metathesis/Heck-cyclisation-elimination sequence.

Heck reactions were performed on α,β-unsaturated-δ-sulfonamido intermediates, derived from cross metathesis, to allow the instalment of substituents at the β position. Subsequent one-pot cyclisation/elimination provides an operationally simple, catalytic and convergent synthesis of 2,4,6-trisubstituted pyridines.

Quantifying phosphorus retention and release in rivers and watersheds using extended end-member mixing analysis (E-EMMA).

Extended end-member mixing analysis (E-EMMA) is presented as a novel empirical method for exploring phosphorus (P) retention and release in rivers and watersheds, as an aid to water-quality management. E-EMMA offers a simple and versatile tool that relies solely on routinely measured P concentration and flow data. E-EMMA was applied to two river systems: the Thames (U.

Impacts of tropical cyclones on U.S. forest tree mortality and carbon flux from 1851 to 2000.

Tropical cyclones cause extensive tree mortality and damage to forested ecosystems. A number of patterns in tropical cyclone frequency and intensity have been identified. There exist, however, few studies on the dynamic impacts of historical tropical cyclones at a continental scale.

"Empty" sac in pregnant women with bleeding: are measurements answering the right question?

Purpose: To assess the percentage of first-trimester pregnancies with bleeding that demonstrate a visible sac but lack an identifiable embryo and have a mean sac diameter (MSD) in the controversial range of 16-20 mm.

Methods: Retrospective study of all first-trimester sonograms among women with vaginal bleeding during a 4-year interval.

Results: The study cohort consisted of 546 first- trimester sonograms.

Recapturing a Context for Psychology: The Role of History.

With the ever-increasing fragmentation of psychology into narrower subspecialties, the field devolves further and further into a focus on specialized knowledge, answering smaller questions and avoiding the larger and more meaningful ones. It is argued that specialized knowledge acquires its meaning only from an understanding of its place in a broader intellectual context. Psychology appears to have lost that context and perhaps the opportunity for a more significant role in modern science.

Five-millimeter and smaller embryos without embryonic cardiac activity: outcomes in women with vaginal bleeding.

Objective: The purpose of this study was to assess outcomes in embryos with a crown-rump length (CRL) of 5 mm or less without embryonic cardiac activity (ECA) among pregnant women with vaginal bleeding in the first trimester.

Methods: A retrospective study of all first-trimester sonograms in women with vaginal bleeding from 1999 to 2002 was conducted.

Results: Thirty-seven embryos without detectable ECA that had a CRL of 5 mm or less were identified.

Thirty-year trends in suspended sediment in seven Lake Erie tributaries.

Sediment is an important pollutant for Lake Erie and its tributaries as a carrier of other substances and as a pollutant in its own right. Environmental managers have called for major reductions in sediment loadings in Lake Erie tributaries. In this study, 30-yr (1975-2005) datasets with daily resolution are analyzed to identify and interpret trends in sediment concentrations and loads in major US tributaries to Lake Erie.

Hurricane Katrina's carbon footprint on U.S. Gulf Coast forests.

Hurricane Katrina's impact on U.S. Gulf Coast forests was quantified by linking ecological field studies, Landsat and Moderate Resolution Imaging Spectroradiometer (MODIS) image analyses, and empirically based models.

The Howard Crosby Warren Medal: psychology's first award.

This article explores the development of the first major award given in American psychology, the Howard Crosby Warren Medal. Administered by the Society of Experimental Psychologists, the award was first given in 1936. The first recipients of the Howard Crosby Warren Medal were Ernest G.

Estimating the economic burden from illnesses associated with recreational coastal water pollution--a case study in Orange County, California.

A cost-of-illness framework was applied to health and income data to quantify the health burden from illnesses associated with exposure to polluted recreational marine waters. Using data on illness severity due to exposure to polluted coastal water and estimates of mean annual salaries and medical costs (adjusted to 2001 values) for residents of Orange County, California, we estimated that the economic burden per gastrointestinal illness (GI) amounts to 36.58 dollars, the burden per acute respiratory disease is 76.
