Measuring the societal value of lifetime health
This paper considers two societal concerns in addition to health maximisation: first, concerns for the societal value of lifetime health for an individual; and second, concerns for the value of lifetime health across individuals. Health-related social welfare functions (HRSWFs) have addressed only the second concern. We propose a model that expresses the former in a metric â the adult healthy-year equivalent (AHYE) â that can be incorporated into standard HRSWFs. An empirical study based on this formulation shows that both factors matter: health losses in childhood are weighted more heavily than losses in adulthood and respondents wish to reduce inequalities in AHYEs

Solutions of the Knizhnik - Zamolodchikov Equation with Rational Isospins and the Reduction to the Minimal Models
In the spirit of the quantum Hamiltonian reduction we establish a relation
between the chiral -point functions, as well as the equations governing
them, of the WZNW conformal theory and the corresponding Virasoro
minimal models. The WZNW correlators are described as solutions of the Knizhnik
- Zamolodchikov equations with rational levels and isospins. The technical tool
exploited are certain relations in twisted cohomology. The results extend to
arbitrary level and isospin values of the type , $ \
2j, 2j' \in Z\!\!\!Z_+$.Comment: 40 page
Competition between Pauli and orbital effects in a charge-density wave system
We present angular dependent magneto-transport and magnetization measurements
on alpha-(ET)2MHg(SCN)4 compounds at high magnetic fields and low temperatures.
We find that the low temperature ground state undergoes two subsequent
field-induced density-wave type phase transitions above a critical angle of the
magnetic field with respect to the crystallographic axes. This new phase
diagram may be qualitatively described assuming a charge density wave ground
state which undergoes field-induced transitions due to the interplay of Pauli
and orbital effects.Comment: 11 pages, 4 figures, shown at the APS march meeting 2000, appears in

Will systems biology offer new holistic paradigms to life sciences?
A biological system, like any complex system, blends stochastic and deterministic features, displaying properties of both. In a certain sense, this blend is exactly what we perceive as the âessence of complexityâ given we tend to consider as non-complex both an ideal gas (fully stochastic and understandable at the statistical level in the thermodynamic limit of a huge number of particles) and a frictionless pendulum (fully deterministic relative to its motion). In this commentary we make the statement that systems biology will have a relevant impact on nowadays biology if (and only if) will be able to capture the essential character of this blend that in our opinion is the generation of globally ordered collective modes supported by locally stochastic atomisms

Fauna living in colonies of Mussismilia hispida (Verrill) (Cnidaria: Scleractinia) in four South-eastern Brazil islands
Colonies of Mussismilia hispida were collected in four south-eastern Brazil islands and fixed in formalin. Volume, living and basal areas of each coral head were measured. Animals found over, under and inside the corals were sorted, resulting in 9657 specimens belonging to more than 130 taxa. The underside of the colonies was occupied by bivalves and colonial forms of sponges, bryozoans and ascidians. On the living surface, barnacles and cryptochiridean crabs were detected. The endolithic animals included polychaetes, bivalves and sipunculid worms. Most of the animals collected were vagile microcrustaceans. In general, the corals in this ecosystem: (1) act as a nursery place for the community; (2) provide protection for many species also found in other habitats; (3) support a community mainly omnivorous and detritivorous; (4) are initially colonised randomly.<br>ColĂŽnias de Mussismilia hispida foram coletadas em quatro ilhas do sudeste brasileiro e fixadas em formalina. Depois de medidos o volume e as areas vivas e da base de cada coral, os animais encontrados sobre, dentro e sob as colĂŽnias foram triados, resultando em 9657 espĂ©cimes, pertencentes a cerca de 130 espĂ©cies. As bases das colĂŽnias encontravam-se ocupadas por bivalves e colĂŽnias de esponjas, briozoĂĄrios e ascĂdias; na superfĂcie viva, cirripĂ©dios e "caranguejos-galha" se fizeram presentes; a fauna endolĂtica incluiu poliquetas, bivalves e sipĂșnculos. CrustĂĄceos vĂĄgeis, tais como copĂ©podes, isĂłpodes, anfĂpodes, tanaidĂĄceos e ostrĂĄcodes responderam pela maioria dos animais encontrados. De maneira geral, pode-se dizer que os corais neste ambientes: (1) atuam como um local protegido para a reprodução das espĂ©cies associadas; (2) fornecem abrigo a muitas espĂ©cies tambĂ©m encontradas em outros ambientes; (3) sustentam uma comunidade que se alimenta principalmente de bactĂ©rias, detritos e do muco dos corais; (4) sĂŁo inicialmente colonizados ao acaso
