Natural resource managers face complex challenges in addressing non-point source water pollution. A participatory modeling approach was applied in the St. Albans Bay watershed to identify the most effective phosphorus control options to achieve the load reductions required by the Lake Champlain Phosphorus Total Maximum Daily Load (TMDL). Stakeholders participated in the collection of data in th...

Microplastic litter is a pervasive pollutant present in marine systems across the globe. The legacy of microplastics pollution in the marine environment today may remain for years to come due to the persistence of these materials. Microplastics are emerging contaminants of potential concern and as yet there are few recognized approaches for monitoring. In 2008, the EU Marine Strategy Framework ...

10 Because all models are a simplification of the phenomenon they aim to represent, it is 11 often more useful to estimate the probability of an event rather than a single “best” model 12 result. Previous air quality ensemble approaches have used computationally expensive 13 simulations of separately developed modeling systems. We present an efficient method 14 to generate ensembles with hundre...

In positive systems, inputs, state variables and outputs take only non-negative values. Examples of positive systems are industrial processes involving chemical reactors, heat exchangers and distillation columns, storage systems, compartmental systems, or water and atmospheric pollution models. A variety of models revealing the behaviour of positive linear systems can be found in engineering, m...

An analysis of the existing data on the atmospheric neutrino anomaly is presented , focused on the statistical signiicance that can be attributed to its experimental evidence. Our approach is alternative to the usual analyses in terms of the =e ratio of event rates. In fact, we perform a comparison between data and expectations, by separating the information on e-like and-like events, with a ca...

In positive systems, the inputs, state variables and outputs take only non-negative values. Examples of positive systems are industrial processes involving chemical reactors, heat exchangers and distillation columns, storage systems, compartmental systems, or water and atmospheric pollution models. A variety of models having positive linear system behaviour can be found in engineering, manageme...

Collective bargaining in Germany takes place at either industry or firm level. As in the majority of OECD countries, collective bargaining coverage is much higher than union density. Not all employees in a covered firm are necessarily covered. This institutional setup suggests to explicitly distinguish union density in a labor market segment, coverage at the firm level, and coverage at the indi...

Instead of having been more or less constant, as once assumed, it is now apparent that the major ion chemistry of the oceans has varied substantially over time. For instance, independent lines of evidence suggest that calcium concentration ([Ca ]) has approximately halved and magnesium concentration ([Mg ]) approximately doubled over the last 100 million years. On the other hand, the calcite co...

Wage dispersion is generated in a sequential search environment through heterogeneity in firm productivity along with an individual wage-effort tradeoff. For a given degree of TFP dispersion, the framework can generate any amount of wage dispersion. Calibrated to generate realistic gains from trade, it is able to generate the kind of wage dispersion observed in data. JEL codes: E24, J64

In the perspective of a sustainable urban planning, it is necessary to investigate cities in a holistic way and to accept surprises in the response of urban environments to a particular set of strategies. For example, the process of inner-city densification may limit air pollution, carbon emissions, and energy use through reduced transportation; on the other hand, the resulting street canyons c...
