Dramatising the score: an action research investigation of the use of Mozart’s Magic Flute as performance guide for his clarinet Concerto
With this project we tried to go beyond the score, looking for alternative sources that could help in the performance of a piece. In order to do this we worked with Mozart’s clarinet concerto with the assistance of five conservatory clarinet students over a period of two months. Adopting the research techniques of an action research project we created a study method that helped to better understand the concerto, seeing the music like a large theatre play where the characters interact telling a story, and in doing so,
giving a greater meaning to what we try to communicate. In doing this we transformed the concerto into a ‘Magic Clarinet’ Opera. In the conclusions we refer to several psychological theories, suggesting that this method might benefit performance students at all levels
Non-ergodic states induced by impurity levels in quantum spin chains
The semi-infinite XY spin chain with an impurity at the boundary has been
chosen as a prototype of interacting many-body systems to test for non-ergodic
behavior. The model is exactly solvable in analytic way in the thermodynamic
limit, where energy eigenstates and the spectrum are obtained in closed form.
In addition of a continuous band, localized states may split off from the
continuum, for some values of the impurity parameters. In the next step, after
the preparation of an arbitrary non-equilibrium state, we observe the time
evolution of the site magnetization. Relaxation properties are described by the
long-time behavior, which is estimated using the stationary phase method.
Absence of localized states defines an ergodic region in parameter space, where
the system relaxes to a homogeneous magnetization. Out of this region, impurity
levels split from the band, and localization phenomena may lead to
non-ergodicity.Comment: 10 pages, 5 figures. arXiv admin note: substantial text overlap with

The O’Neill Institute for National and Global Health Law: Discovering Innovative Solutions for the Most Pressing Health Problems Facing the Nation and the World
The connection between health and an individual’s ability to function in society, as well as the importance of health to a society’s economic, political, and social wellbeing necessitates finding innovative solutions to the world’s most pressing health problems. The O’Neill Institute for National and Global Health Law at Georgetown University seeks to demonstrate the role that academia can play in addressing complex national and global health problems in a comprehensive, evidence-based, intellectually-rigorous, and nonpartisan manner. The O’Neill Institute currently has three research programs: global health law, national health law, and the center for disease prevention and outcomes. Projects within these programs examine a broad range of health law and policy issues, such as global health governance, global tobacco control, health worker migration, emergency preparedness, national and Chinese health reform, HIV and AIDS issues, food safety, and personalized medicine. These projects merge the scholarly capacity within the institute with the resources of its partners, which include the World Health Organization, World Bank, the Bill & Melinda Gates Foundation, the U.S. Centers for Disease Control and Prevention, and the Campaign for Tobacco Free Kids. Additionally, the faculty and fellows of the O’Neill Institute regularly produce high-level scholarship and engage in teaching offering multi-disciplinary course offerings and innovative graduate degree programs.

Effect of soil-ph and organic-matter on labile aluminium in soils under permanent grass
The rates of extraction of Na, K, Mg, Ca, and Al with 1M NH4 NO3 from the mineral-and organic-rich layers of some Park Grass (Rothamsted) soils were measured at the pH of the soil. Below pH 3.7 exchangeable Al, derived from the kinetics curve, increases with decreasing soil pH and is less in the organic-rich layer. The sum of the basic exchangeable cations, ¿(Na + K + Mg + Ca), increases with increasing soil pH and is more in the organic-rich layer. The extraction of exchangeable Al obeys first order kinetics, the rate constant being similar for all the soils (mean value 36 ± 7 × 10¿6|s¿1), which implies that exchangeable Al is released from surfaces with similar properties for the adsorption of Al, and that the rate is not affected by soil pH and organic matter. The rate of extraction of non-exchangeable Al is the same in the mineral-and organic-rich layers of each soil, and is maximal at about pH 3.7, decreasing sharply at more and less acid pH values.Peer Reviewe
Advancing the Right to Health: The Vital Role of Law
Effective laws and an enabling legal environment are essential to a healthy society. Most public health challenges – from infectious and non-communicable diseases to injuries, from mental illness to universal health coverage – have a legal component. At global, national and local levels, law is a powerful tool for advancing the right to health. This tool is, however, often underutilized.
This report aims to raise awareness about the role that public health laws can play in advancing the right to health and in creating the conditions for all people to live healthy lives. The report provides guidance about issues and requirements to be addressed during the process of developing or reforming public health laws, with case studies drawn from countries around the world to illustrate effective practices and critical features of effective public health legislation.
Advancing the right to health: the vital role of law is the result of a collaboration between the World Health Organisation, the International Development Law Organisation (IDLO), the O’Neill Institute for National and Global Health Law, Washington D.C., USA, and Sydney Law School, University of Sydney. The Project Directors were: Professor Lawrence O. Gostin, Linda D. and Timothy J. O’Neill Professor of Global Health Law and University Professor, Georgetown University; Faculty Director, O’Neill Institute for National and Global Health Law, Georgetown University; Mr David Patterson, Senior Legal Expert – Health; Department of Research & Learning, International Development Law Organization; Professor Roger Magnusson, Professor of Health Law & Governance, Sydney Law School, University of Sydney; Mr Oscar Cabrera, Executive Director, O’Neill Institute for National and Global Health Law, Georgetown University Law Center; Ms Helena Nygren-Krug (2011–2013), Senior Advisor, Human Rights & Law, UNAIDS.
The content and structure of the report reflect the consensus reached at the second of two international consultations in public health law that preceded the preparation of the report, hosted by WHO and IDLO in Cairo, Egypt, 26-28 April 2010. Part 1 introduces the human right to health and its role in guiding and evaluating law reform efforts, including efforts to achieve the goal of universal health coverage.
Part 2 discusses the process of public health law reform. The law reform process refers to the practical steps involved in advancing the political goal of law reform, and the kinds of issues and obstacles that may be encountered along the way. Part 2 identifies some of the actors who may initiate or lead the public health law reform process, discusses principles of good governance during that process, and ways of building a consensus around the need for public health law reform.
Part 3 turns from the process of reforming public health laws to the substance or content of those laws. It identifies a number of core areas of public health practice where regulation is essential in order to ensure that governments (at different levels) discharge their basic public health functions. Traditionally, these core areas of public health practice have included: the provision of clean water and sanitation, monitoring and surveillance of public health threats, the management of communicable diseases, and emergency powers.
Building on these core public health functions, Part 3 goes on to consider a range of other public health priorities where law has a critical role to play. These priorities include tobacco control, access to essential medicines, the migration of health care workers, nutrition, maternal, reproductive and child health, and the role of law in advancing universal access to quality health services for all members of the population. The report includes many examples that illustrate the ways in which different countries have used law to protect the health of their populations in ways that are consistent with their human rights obligations. Countries vary widely in terms of their constitutional structure, size, history and political culture. For these reasons, the examples given are not intended to be prescriptive, but to provide useful comparisons for countries involved in the process of legislative review

IcnologÃa: huellas bajo la lupa
Una de las lÃneas de investigación que desarrolla el LGA es la icnologÃa (ichnos: trazas, huellas; logos: estudio), como su etimologÃa lo indica es la ciencia que se ocupa del estudio de trazas recientes y fósiles hechas por organismos. Para ejemplificar una traza reciente tratemos de imaginar un ambiente de invierno de Ushuaia; la nieve recién caÃda nosotros caminando sobre ella y dejando huellas, trazas, que en este caso y como pasa generalmente con las huellas que dejan los vertebrados son fáciles de asociar con el productor. Las huellas en la nieve, no tienen potencial de preservación, pero si las huellas están realizadas en substratos como por ejemplo el limo o el barro empapado en agua, es muy probable que se preserven en el registro geológico constituyendo una traza fósil. La rastrillada de los dinosaurios es un ejemplo de traza fósil, en la Figura 1 la traza fósil Titanopodus mendozensis fue conservada en sedimentos que formaban una planicie deltaica. Una traza fósil es una estructura preservada en el sedimento, es de origen biológico y refleja el comportamiento del organismo que la produce. Tomando como ejemplo la Figura 1, la rastrillada (una estructura preservada) fue hecha por titanosaurios (organismos) cuando se desplazaban de un lugar a otro (comportamiento). Este comportamiento se encuadra dentro de las trazas de locomoción o movimiento.Fil: Lopez Cabrera O., Maria Isabel. Consejo Nacional de Investigaciones CientÃficas y Técnicas.
