Decorrelation estimates for random discrete Schr\"odinger operators in dimension one and applications to spectral statistics

The purpose of the present work is to establish decorrelation estimates for some random discrete Schrodinger operator in dimension one. We prove that the Minami estimates are consequences of the Wegner estimates and Localization. We also prove decorrelation estimates at distinct energies for the random hopping model and Schrodinger operators with alloy-type potentials. These results are used to give a description of the spectral statistics

Medical Licensing: An Obstacle to Affordable, Quality Care

In the United States, the authority to regulate medical professionals lies with the states. To practice within a state, clinicians must obtain a license from that state's government. State statutes dictate standards for licensing and disciplining medical professionals. They also list tasks clinicians are allowed to perform. One view is that state licensing of medical professionals assures quality. In contrast, I argue here that licensure not only fails to protect consumers from incompetent physicians, but, by raising barriers to entry, makes health care more expensive and less accessible. Institutional oversight and a sophisticated network of private accrediting and certification organizations, all motivated by the need to protect reputations and avoid legal liability, offer whatever consumer protections exist today. Consumers would benefit were states to eliminate professional licensing in medicine and leave education, credentialing, and scope-of-practice decisions entirely to the private sector and the courts. If eliminating licensing is politically infeasible, some preliminary steps might be generally acceptable.States could increase workforce mobility by recognizing licenses issued by other states. For mid-level clinicians, eliminating education requirements beyond an initial degree would allow employers and consumers to select the appropriate level of expertise. At the very least, state legislators should be alert to the self-interest of medical professional organizations that may lie behind the licensing proposals brought to the legislature for approval

Using Toulmin’s Argument Pattern in the evaluation of argumentation in school science

Toulmin's definition of argument has been used by researchers as a theoretical perspective on argument and as a methodological tool for analysing episodes of oral argumentation. An adaptation of Toulmin's framework used by researchers has informed a professional development programme for teachers. Research on the impact of the programme on pedagogic practice shows that Toulmin-based materials are advantageous in helping teachers to conceptualise argument and model it for students. However focus on the process of argumentation limits any consideration of the content and quality of evidence. Toulmin's framework can also be used to evaluate student outcomes when using argumentation software
