presented. Unlike most of the prominent codes based on
finding a process that predicts the future data, these
codes are based on function analysis and symbolic
regression. Both codes are based on a generalization
and combination of series expansions, parameter
optimization techniques, and genetic programming. These
highly complex codes are outlined and applied to
different examples of physics and economy.Sat Jun 14 22:15:23 CEST 2008An Introduction to Ecological Economics (e-book)1997ecosystem_service ebook Costanza ecology economy Mon Jun 09 15:15:08 CEST 2008Social Psychology of the Workplace283-306Advances in Group ProcessesHow not to Build an Online Market: The Sociology of Market Microstructure232006trust sociology economy online This paper examines the attempts to create new online markets for the trading of wholesale standardized goods during the late 1990’s. The vast majority of these business-to-business (“B2B”) exchanges failed. These failed attempts provide invaluable data on the necessary underpinnings of online commodity markets and the social dynamics that drive them. Focusing on the US market for propane as our case, we discuss the model that drove the development of many business-to-business exchanges, the social dynamics of the propane industry and the attempts to create an online propane market, the role of informal risk management, and some initial lessons about the design of markets. Ignoring the behavioral realities of markets led to designs and technology that in many cases were incompatible with the needs of market participants.Wed May 28 17:25:15 CEST 2008Functional traits underlie the delivery of ecosystem services across different trophic levels2008economy RUBICODE traits ecosystem_service bioenergy_fauna ecosystem_function Functional traits of organisms can serve as tools for predicting and
quantifying ecosystem
service delivery in response to biodiversity loss. We collected published
studies (~250)
proving effects of functional traits on various ecosystem services,
and the underlying
ecosystem processes, across different trophic levels. The majority
of studies considered plants
and soil invertebrates, but relationships have been documented for
a range of other organisms
and habitats. Within each trophic level, specific processes and services
are affected by a
combination of traits. At the same time, particular traits are involved
simultaneously in the
control of different processes, resulting in predictable clusters
of traits and services. Particular
associations were shown between traits of plants and soil organisms
that underlie ecosystem
nutrient economy, herbivory control and fodder and fibre production.
The review
demonstrates the potential for integrating the functional traits approach
into predictive models
of ecosystem services and providing a common currency for multiple
service delivery
assessments.Mon May 26 17:10:16 CEST 2008Raumprobleme in der Tafelmalerei der Gotik: Kunstgeographische und wirtschaftsgeschichtliche Untersuchungen über Köln, Nürnberg, Augsburg und Ulm [Problems of space in Gothic panel painting: art geography and economic-historical investigations of Cologne, Nuremberg, Augsburg and Ulm]?painting gothic economy cologne augsburg art medieval nuremberg history geography ulm Geographic distribution of painting centers.Wed May 21 15:28:31 CEST 2008Functional traits underlie the delivery of ecosystem services across different trophic levels2008traits RUBICODE ecosystem_function ecosystem_service economy Functional traits of organisms can serve as tools for predicting and

for human food has not previously been evaluated and the previous
estimates for countries or continents have seldom used primary data.
In this review, we expand the previous estimates using novel primary
data from 200 countries and found that fruit, vegetable or seed production
from 87 of the leading global food crops is dependent upon animal
pollination, while 28 crops do not rely upon animal pollination.
However, global production volumes give a contrasting perspective,
since 60% of global production comes from crops that do not depend
on animal pollination, 35% from crops that depend on pollinators,
and 5% are unevaluated. Using all crops traded on the world market
and setting aside crops that are solely passively self-pollinated,
wind-pollinated or parthenocarpic, we then evaluated the level of
dependence on animal-mediated pollination for crops that are directly
consumed by humans. We found that pollinators are essential for 13
crops, production is highly pollinator dependent for 30, moderately
for 27, slightly for 21, unimportant for 7, and is of unknown significance
for the remaining 9. We further evaluated whether local and landscape-wide
management for natural pollination services could help to sustain
crop diversity and production. Case studies for nine crops on four
continents revealed that agricultural intensification jeopardizes
wild bee communities and their stabilizing effect on pollination
services at the landscape scale.Wed May 21 10:35:59 CEST 2008Organisation for Economic Co-operation and Development1-57Round Table on Sustainable Development.

In only a very few countries do biofuels have the potential to make a significant dent in dependence
on imported oils. The amount of fossil fuels that can be displaced by domestic production of biofuels will
be small in the great majority of countries. What’s more, an augmented biofuels market will tend to
increase the positive relation between oil prices and biofuel costs. Higher oil prices will both raise the
production cost of biofuels (as fossil fuels are an important input in the production process) and exert
upward pressure on agricultural commodity prices as a result of the increased demand for them. This limits
the possibility for biofuels to reduce transport fuel prices.
