We consider a two-period portfolio problem with predictable assets returns. First-order (second-order) predictability means that an increase in the first period return yields a first-order (second-order) stochastically dominated shift in the distribution of the second period state prices. Mean reversion in stock returns, Bayesian learning, stochastic volatilities and stochastic interest rates (...

Extended communication and advanced cooperation in a permanently growing healthcare and welfare domain require a well-defined set of security services provided by an interoperable security infrastructure based on international and European standards. Any communication and collaboration procedure requires a purpose. But such legal purpose-binding is definitely not the only aspect to carefully be...

Life expectancy and disease rates in the United States differ starkly among Americans depending on their demographic characteristics and where they live. Although health care systems are taking important steps to reduce inequities, meaningful progress requires interventions outside the clinic, in sectors such as employment, housing, transportation, and public safety. Inequities exist in each of...

A very ’physical’ approach to this phenomenon can be made by making use of the linearity of Stokes equations and symmetries of the system. Here, we preform detailed calculations according to hints from Exercise 2.9 from the textbook [Kim & Karilla]. As the Stokes equations are linear in p and v, the pressure field p(r) can be written as a scalar product of a certain vector field P(r) and the po...

Previous Proposals and Problems Regarding the key question, two main streams of proposals are basically discernible. One stream maintained that both NP1 and NP2 are subject, trying to define various notions of subject: e.g., Yu (1909) called them big and small subject, Yoon (2003, 2007) major and grammatical subject, and Lee (2007) subject [Spec, RefP] and subject [Spec, TP], respectively. The ...

Alchemy was the synthesis or transmutation of all elements in perfect balance to obtain the philosopher's stone, the key to health. Just as alchemists sought this, so health practitioners always seek the best possible practice for optimal health outcomes for our patients. Best practice requires full knowledge--a little information can be dangerous. We need to serve our apprenticeship before we ...

It is the aim of the Cochrane Collaboration to gather, summarise and disseminate evidence of health care interventions. Recently, the Occupational Health Field has started to do so for occupational health interventions. In this article we would like to describe the organisation and the methods used by the Field. First, the use of research information to improve the quality of occupational healt...
