Uncertainty is an intrinsic feature of complex ecological models. Given that it is not possible to rid the models from uncertainty, we are left with taking notice of it for consideration in model-based decision making. Traditional ecological modelling methods and tools do not support explicit accounts of model uncertainty. This work gives a contribution towards making known, or bringing to the ...

Anthropogenic activity has a negative impact on many coastal ecosystems, compromising the significant direct and indirect socio-economic benefits provided in these areas. Maintaining activities that depend on coastal zones while preserving the ecological state of the ecosystems represents a management challenge. Management of coastal zones requires scientifically based knowledge, due to the com...

Multi-agent systems (MAS) open new modelling and analysis perspectives in ecological and social sciences. An original characteristic of the Companion Modelling (ComMod) approach adopted in this case study is the co-construction and use of a MAS model with and for local stakeholders such as farmers and local administrators. Alternating iteratively field and modelling activities, this approach fa...

Ecological indicators, historical land use, and invasive species detection in the lower Iowa River floodplain." MA has been approved by the Examining Committee for the thesis requirement for the Master of Arts degree in Geography at the May 2014 graduation.

The current study used ecological momentary assessment to test several tenets of the reserve capacity model (L.C. Gallo & K. A. Matthews, 2003). Women (N = 108) with varying socioeconomic status (SES) monitored positive and negative psychosocial experiences and emotions across 2 days. Measures of intrapsychic and social resources were aggregated to represent the reserve capacity available to ma...

We address the question how citation-based bibliometric indicators can best be normalized to ensure fair comparisons between publications from different scientific fields and different years. In a systematic large-scale empirical analysis, we compare a traditional normalization approach based on a field classification system with three source normalization approaches. We pay special attention t...

The ability to achieve ecological sustainability and the sustainable development of marine and estuarine ecosystems constitutes a complex major challenge and depends on many driving forces, often conflicting with each other. In particular, there are three major drivers: (a) the search for human well-being, health and safety, (b) the maintenance of ecological sustainability and environmental equ...

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...
