In a work of Just, Miller, Scheepers and Szeptycki it was asked whether certain diagonalization properties for sequences of open covers are provably closed under taking finite or countable unions. In a recent work, Scheepers proved that one of the properties in question is closed under taking countable unions. After surveying the known results, we show that none of the remaining classes is prov...

political and policy settlement further institutionalised surveillance as the basis of the MCHS. The restructured Service has remained constrained by the dominance of health surveillance as the primary program goal even after more varied contracting arrangements replaced CCT. Although recent initiatives indicate signs of hange, narrow surveillancebased guidelines for Victorian MCH Services are ...

We present a flexible method for policy-oriented ecological prediction based on a Bayesia n network. The graphical structure explicitly represents cause-and-effect assumptions between ecosystem variables that may be obscured under other approaches. These assumptions allow the complex causal chain linking management actions to ecological consequences to be factored into an articulated sequence o...

Abstract The paper proposes an agent-based evolutionary ecological-economic model that captures the link between economy and ecosystem in a more inclusive way than standard economic optimization models do. We argue approach is required to understand integrated dynamics of both systems, i.e. micro–macro feedbacks. In paper, we illustrate claim by analyzing non-triviality finding sustainability p...

a r t i c l e i n f o Similar to circumstances in the field of economics, market fundamentalism dominates urban blight policy spaces in the U.S. despite criticisms of the paradigm. Unlike the unified alternative that ecological economics (EE) provides to conventional economic theory, however, disagreement over the meaning of " blight " has prevented a commonly held pre-analytic vision and polic...

Prevention researchers have found that drinking in different contexts is related to different alcohol problems. Where and with whom people drink affects the types of alcohol-related problems they experience. Consequently, identifying those contexts that result in the greatest number of problems provides a novel opportunity to target new prevention efforts aimed at those contexts. However, ident...

China leads the world in afforestation, and is one of the few countries whose forested area is increasing. However, this massive "greening" effort has been less effective than expected; afforestation has sometimes produced unintended environmental, ecological, and socioeconomic consequences, and has failed to achieve the desired ecological benefits. Where afforestation has succeeded, the approa...

The aim of the System Dynamics Model ESCOT is to describe a path towards a sustainable transport system in Germany and to assess its economic impacts. ESCOT was developed within the environmentally sustainable transport (EST) project of the OECD that was designed to consider the ecological and technical aspects of a transition towards sustainable transportation. ESCOT comprises five models: the...

One of the most ambitious ecological studies of the past few decades was the Millennium Ecosystem Assessment (MA), which examined the consequences of ecosystem change for human well-being. The MA developed global ecological scenarios as a process to inform policy options, despite enormous uncertainties. These scenarios were based on an interlocking suite of models that forecast the future. Foll...
