Grasping at straws: a ratings downgrade for the emerging international financial architecture

Following the Asia crisis of 1997-98, policymakers invested a great deal of energy in designing a new international financial architecture. However many of the policy proposals which have emerged from think tanks and the multilateral agencies have proven unworkable or politically unpalatable. The debate focuses on state-led initiatives. But the assumption that public policy is by definition an output of public institutions is difficult to sustain in an era of global change. This paper considers specialized forms of intelligence-gathering and judgment-determination which seem increasingly important as sources of governance in this era of financial market volatility. These agents - embedded knowledge networks (EKNs) - include the major bond rating agencies, Moody’s Investors Service and Standard and Poor’s, the focus of this paper. The Basel Committee has put forward a serious proposal to reform the existing capital adequacy framework which uses banks' own internal ratings and external bond ratings to calculate bank risk-weighted capital requirements. The paper shows that there are potentially unexpected consequences from using private rating agencies as a substitute for state-based regulation, due to the organizational incentives that shape the ratings industry. Cementing these organizational incentives into the emerging financial architecture will give rise to negative social and economic consequences

Making Voting Easier: Convenience Voting in the 2008 Presidential Election

In this study we analyze the choice of voting mode in the 2008 presidential election. We use a large-sample survey with national coverage that allows us to overcome limitations of previous studies. Our analysis provides a number of insights into some of the important debates about convenience voting. Among other things, we find little support for the hypothesis that convenience voting methods have partisan implications; although we do find voter attributes that lead to the choice of some particular convenience voting mode. Results like these have important implications for future moves towards convenience voting and the design of new outreach campaigns.Pew Charitable Trust

Prehospital critical care is associated with increased survival in adult trauma patients in Scotland

Background Scotland has three prehospital critical care teams (PHCCTs) providing enhanced care support to a usually paramedic-delivered ambulance service. The effect of the PHCCTs on patient survival following trauma in Scotland is not currently known nationally. Methods National registry-based retrospective cohort study using 2011-2016 data from the Scottish Trauma Audit Group. 30-day mortality was compared between groups after multivariate analysis to account for confounding variables. Results Our data set comprised 17 157 patients, with a mean age of 54.7 years and 8206 (57.5%) of male gender. 2877 patients in the registry were excluded due to incomplete data on their level of prehospital care, leaving an eligible group of 14 280. 13 504 injured adults who received care from ambulance clinicians (paramedics or technicians) were compared with 776 whose care included input from a PHCCT. The median Injury Severity Score (ISS) across all eligible patients was 9; 3076 patients (21.5%) met the ISS>15 criterion for major trauma. Patients in the PHCCT cohort were statistically significantly (all p < 0.01) more likely to be male; be transported to a prospective Major Trauma Centre; have suffered major trauma; have suffered a severe head injury; be transported by air and be intubated prior to arrival in hospital. Following multivariate analysis, the OR for 30-day mortality for patients seen by a PHCCT was 0.56 (95% CI 0.36 to 0.86, p=0.01). Conclusion Prehospital care provided by a physician-led critical care team was associated with an increased chance of survival at 30 days when compared with care provided by ambulance clinicians

Candidate molecular ions for an electron electric dipole moment experiment

This paper is a theoretical work in support of a newly proposed experiment (R. Stutz and E. Cornell, Bull. Am. Soc. Phys. 89, 76 2004) that promises greater sensitivity to measurements of the electron's electric dipole moment (EDM) based on the trapping of molecular ions. Such an experiment requires the choice of a suitable molecule that is both experimentally feasible and possesses an expectation of a reasonable EDM signal. We find that the molecular ions PtH+, HfH+, and HfF+ are suitable candidates in their low-lying triplet Delta states. In particular, we anticipate that the effective electric fields generated inside these molecules are approximately of 73 GV/cm, -17 GV/cm, and -18 GV/cm respectively. As a byproduct of this discussion, we also explain how to make estimates of the size of the effective electric field acting in a molecule, using commercially available, nonrelativistic molecular structure software.Comment: 25 pages, 3 figures, submitted to Physical Review

The Balance Between Preventing Fraud and Ensuring Participation: Attitudes Towards Voter Identification in New Mexico

This paper examines public opinion on the effectiveness and consequences of voter identification laws in New Mexico. In particular, it focuses on the attitudes central to the court reasoning in the 2008 Supreme Court case which upheld an Indiana photo-ID law, Crawford v. Marion County Election Board. Questions include whether or not voters think the ID laws protect against fraud and prevent legitimate participation, as well as which point of view voters find more compelling and whether or not attitudes towards voter identification are related to voter confidence. While most voters think that voter ID laws prevent fraud, many voters think that ensuring access to the polls is more important than preventing fraud. Among other variables that explain differences among individuals, partisanship plays an important role.Caltech/MIT Voting Technology Projec

Australia Telescope Search for Cosmic Microwave Background Anisotropy

We have made an 8.7 GHz image of a sky region with a resolution of 8 arcmin and high brightness sensitivity using the Australia Telescope Compact Array (ATCA). in an ultra compact configuration. The foreground discrete-source confusion was estimated from observations with higher resolution at the same frequency and in a scaled array at a lower frequency. Following the subtraction of the foreground confusion, the field shows no features in excess of the instrument noise. This limits the CMB anisotropy flat-band power to Q_flat < 23.6 microK with 95 per cent confidence; the ATCA filter function F_l in multipole l-space peaks at l_eff = 4700 and has half maximum values at l = 3350 and 6050.Comment: Tex, 10 pages with 7 embedded figures, uses mn.tex accepted for publication in MNRA

Non-pharmacological treatment modalities for atopic dermatitis

Non-pharmacological measures to improve the management of atopic dermatitis (AD) are as important as pharmacotherapy for true healing of the skin. Skin dryness (which contributes to inflammation, loss of suppleness (leading to fissuring), impaired barrier function, and increased adherence of Staphylococcus aureus organisms) can be overcome by the use of emollients. Ointments and creams provide better barrier function than lotions. Bathing is an important part of the management of AD. Regular, once-daily bathing in warm (not hot) water to hydrate the skin and debride crusts is important. Scented soaps should be avoided and replaced with a moisturising cleanser. After bathing, patients should pat the skin dry and apply emollients immediately. Routine use of topical or systemic antibacterial or antifungal agents is not recommended for AD, but during flares such agents may be invaluable. There is no specific diet for the treatment of AD. Elimination diets are not routine treatment and are potentially harmful. Food elimination should be reserved for those children who have been proven to be allergic to the specific food.http://www.samj.org.zaam201
