  • While prominence in health policy greatly affects the size of the PHI market – in terms of population coverage, contribution to health financing or scope of government interventions – there is no necessary link between the three factors. There are sizeable PHI markets in a range of health systems with diverse mixes of public and private financing. The size of PHI markets may also result from consumer demand for better choice and more comprehensive cover, even where there is little stimulation through policy levers.

  • But how far should the public sector go in defining the terms of maturity transformation?. It would be reassuring to imagine that underlying saving and investment propensities of the private sector define the real interest rate in normal times. Keynes threw some doubt on this classical view. In addition, the fact is that government policies nowadays dominate the terms of maturity transformation in modern economies. Very large government debt defines the yield curve.

  • Global warming and changes in climate have already had observed impacts on natural ecosystems and species. Natural systems such as wetlands, mangroves, coral reefs, cloud forests, Arctic and high latitude ecosystems are especially vulnerable to climate‐induced disturbances. Enhanced protection and management of biological resources and habitats can mitigate impacts and contribute to solutions as nations and communities strive to adapt to climate change. Biodiversity is the foundation and mainstay of agriculture, forests, and fisheries.

  • Communities can play a lead role in assessing and reducing community-level advertising and marketing of unhealthy foods. Important lessons regarding community-based research and advocacy to address marketing of unhealthy products can be borrowed from the alcohol and tobacco control movements. Community-based efforts to decrease excessive advertising and availability of alcohol and tobacco products, particularly in low-income communities, provide a useful case study in how communities can influence marketing practices. ...

  • Shares of the Fund are offered for sale on a continuous basis and may be purchased or redeemed on any Valuation Date at the NAV per share of a particular series. The NAV per share of a series for the purposes of subscription or redemption is computed by dividing the NAV of the Fund attributable to the series (that is, the total fair value of the assets attributable to the series less the liabilities attributable to the series) by the total number of shares of the series of the Fund outstanding at such time.

  • Active database systems require facilities to specify triggers that fire when specified events occur. We propose a language for specifying composite events as eveti expressions, formed using event operators and events (primitive or composite). An event expression maps an event history to anothe-r event history that contains only the events at which the event expression is “satisfied” and at which the trigger should 6re. We present several examples illustrating how quite complex event specifications are possible using event expressions.

  • This article discusses how the flux of cultural productions between centre and periphery works, taking as an example the field of music production in France and Brazil in the 1920s. The life trajectories of Jean Cocteau, French poet and painter, and Heitor Villa-Lobos, a Brazilian composer, are taken as the main reference points for the discussion.

  • Understanding of the transport and attenuation of chemicals in the subsurface is fundamental to effective management of risks posed by chemicals and their possible impact on groundwater resources. A risk assessment approach to groundwater protection incorporates the three-stage combination of source, pathway and receptor. All three must be considered and understood to arrive at a balanced view of the risks to health of groundwater users. Informed consideration of the pathway, which in the context of this monograph means transport through the groundwater system, is vital.

  • A control system should be developed to ensure adequate safeguards to prevent loss, damage, or theft of property. A physical inventory of the property should be taken at least once every two years. The results of the inventory should be reconciled with the property records and any discrepancies should be investigated. In addition, maintenance procedures should be developed to keep the property in good condition. Fixed assets should be recorded at cost. Donated assets should be recorded at fair market value at the time of donation.

  • The prediction of transcription factor binding sites in genomic sequences is in principle very useful to identify upstream regulatory factors. However, when applying this concept to genomes of multi- cellular organisms such as mammals, one has to deal with a large number of false positive predic- tions since many transcription factor genes are only expressed in specific tissues or cell types.

  • One of the key decisions in achieving successful freezing of tissue-engineered products is the choice of cryoprotectant. Cryoprotectants minimize damage caused by ice crystal formation and should induce an amorphous state, rather than ice crystals during the cooling and warming phases. Although the use of cryoprotectants is mandatory, currently available reagents are cytotoxic to some extent. Since tissue-engineered products are larger than isolated cells, longer incubation times with cryoprotectant are necessary which may result in a lower survival rate.
