Some Observations Concerning Plato\u27s Lysis

Discussion of the authenticity and relative dating of the dialogue followed by examination of the several definitions of philos . The Good is the ultimate goal that remains in view to Plato, no matter what else must be abandoned as dialectically unacceptable

Predictions for Impurity-Induced Tc Suppression in the High-Temperature Superconductors

We address the question of whether anisotropic superconductivity is compatible with the evidently weak sensitivity of the critical temperature Tc to sample quality in the high-Tc copper oxides. We examine this issue quantitatively by solving the strong-coupling Eliashberg equations numerically as well as analytically for s-wave impurity scattering within the second Born approximation. For pairing interactions with a characteristically low energy scale, we find an approximately universal dependence of the d-wave superconducting transition temperature on the planar residual resistivity which is independent of the details of the microscopic pairing. These results, in conjunction with future systematic experiments, should help elucidate the symmetry of the order parameter in the cuprates.Comment: 13 pages, 4 figures upon request, revtex version

Beliefs about development versus environmental tradeoffs in the Puget Sound region

Using data from a phone survey of 1,980 Puget Sound residents conducted in 2012, this fact sheet outlines residents’ views about the importance of environmental protection as well as their opinions about energy development, protection of wild salmon, and land use regulation. Seventy-four percent of Puget Sound residents believe that protecting the environment should be a priority even if it means limiting economic growth. The majority of residents favor both increased use of renewable energy (82 percent) and protecting wild salmon (75 percent). Residents are more divided about curbing development, with those from rural areas being more apt to prioritize protecting private property rights over regulating land use.

Urban-rural differences in concern about the environment and jobs in the Puget Sound region

Using data from a phone survey of 1,980 Puget Sound residents conducted in 2012, this fact sheet examines the severity of different environmental problems and compares the strength of concern about the lack of jobs and beliefs about the environment. Too few jobs and the loss of wildlife habitat were the two community issues most likely to be ranked as important problems among residents of Puget Sound. Environmental concern is higher among urban than rural residents, while those in rural areas are more likely than urbanites to believe the lack of jobs is a threat to their community.

Public perceptions of environmental management in the Puget Sound region

Using data from a phone survey of 1,980 Puget Sound residents conducted in 2012, this fact sheet describes public perceptions of different environmental interventions. Puget Sound residents widely support a range of proposed interventions designed to protect and restore the marine environment. These proposals include restricting boating and shipping activities to protect marine mammals such as killer whales and sea lions; more strongly enforcing existing environmental rules and regulations; spending government money to restore the environment for fish and wildlife; and providing tax credits to businesses that voluntarily reduce their environmental impact. Residents are divided about whether existing environmental regulations have benefited their community. Read more about Communities and Coastal Restoration in the Puget Sound Region

Cohort profile: Canadian study of prediction of death, dialysis and interim cardiovascular events (CanPREDDICT)

Background: The Canadian Study of Prediction of Death, Dialysis and Interim Cardiovascular Events (CanPREDDICT) is a large, prospective, pan-Canadian, cohort study designed to improve our understanding of determinants of renal and cardiovascular (CV) disease progression in patients with chronic kidney disease (CKD). The primary objective is to clarify the associations between traditional and newer biomarkers in the prediction of specific renal and CV events, and of death in patients with CKD managed by nephrologists. This information could then be used to better understand biological variation in outcomes, to develop clinical prediction models and to inform enrolment into interventional studies which may lead to novel treatments. Methods/Designs: Commenced in 2008, 2546 patients have been enrolled with eGFR between 15 and 45 ml/min 1.73m2 from a representative sample in 25 rural, urban, academic and non academic centres across Canada. Patients are to be followed for an initial 3 years at 6 monthly intervals, and subsequently annually. Traditional biomarkers include eGFR, urine albumin creatinine ratio (uACR), hemoglobin (Hgb), phosphate and albumin. Newer biomarkers of interest were selected on the basis of biological relevance to important processes, commercial availability and assay reproducibility. They include asymmetric dimethylarginine (ADMA), N-terminal pro-brain natriuretic peptide (NT-pro-BNP), troponin I, cystatin C, high sensitivity C-reactive protein (hsCRP), interleukin-6 (IL6) and transforming growth factor beta 1 (TGFβ1). Blood and urine samples are collected at baseline, and every 6 monthly, and stored at −80°C. Outcomes of interest include renal replacement therapy, CV events and death, the latter two of which are adjudicated by an independent panel. Discussion: The baseline distribution of newer biomarkers does not appear to track to markers of kidney function and therefore may offer some discriminatory value in predicting future outcomes. The granularity of the data presented at baseline may foster additional questions. The value of the cohort as a unique resource to understand outcomes of patients under the care of nephrologists in a single payer healthcare system cannot be overstated. Systematic collection of demographic, laboratory and event data should lead to new insights. The mean age of the cohort was 68 years, 90% were Caucasian, 62% were male, and 48% had diabetes. Forty percent of the cohort had eGFR between 30–45 mL/min/1.73m2, 22% had eGFR values below 20 mL/min/1.73m2; 61% had uACR < 30. Serum albumin, hemoglobin, calcium and 25-hydroxyvitamin D (25(OH)D) levels were progressively lower in the lower eGFR strata, while parathyroid hormone (PTH) levels increased. Cystatin C, ADMA, NT-proBNP, hsCRP, troponin I and IL-6 were significantly higher in the lower GFR strata, whereas 25(OH)D and TGFβ1 values were lower at lower GFR. These distributions of each of the newer biomarkers by eGFR and uACR categories were variable

The Case for Enlarging the House of Representatives

This report makes the case for expanding the House of Representatives to bring the American people a little closer to their government, and their government closer to them. The Case for Enlarging the House of Representatives is an independent byproduct of Our Common Purpose: Reinventing American Democracy for the 21st Century, the final report of the American Academy of Arts and Sciences' Commission on the Practice of Democratic Citizenship. The Commission represents a cross-partisan cohort of leaders from academia, civil society, philanthropy, and the policy sphere who reached unanimous agreement on thirty-one recommendations to improve American democracy. The report takes as a premise that political institutions, civic culture, and civil society reinforce one another. A nation may have impeccably designed bodies of government, but it also needs an engaged citizenry to ensure these institutions function as intended. As a result, Our Common Purpose argues that reforming only one of these areas is insufficient. Progress must be made across all three. To build a better democracy, the United States needs better-functioning institutions as well as a healthier political culture and a more resilient civil society

P6_7 Spider Silk

Spiders silk is often referred to as one of the most amazing materials in nature, with its exceptional strength, able to ensnare insects much greater in size and mass than that of the spider that spun the web. In this paper we explore the idea of using a single piece of spider silk to bring a moving car to a halt. We calculated that a Ford Focus moving at 50 mph could be stopped by a single 10 m long thread with a minimum diameter of 1.88 cm
