Stability and Complexity in Model Ecosystems
, 2019What makes populations stabilize? What makes them fluctuate? Are populations in complex ecosystems more stable than populations in simple ecosystems? In , Robert May addressed these questions in this monograph that has since become a classic. Trained

The terms model and modeling are everyday terms. In science, however, different meanings are ascribed to them, especially when they are viewed from the two perspectives of mathematics and physics. In this chapter, we will examine whether and how these terms are defined in the two disciplines and what significance the use of models and modeling has in ...

Model World: A Model Is a Model Is a Model Is a Model
Interfaces, 1989This occasional column will address issues — both real and imaginary — that impinge on what I think is the main activity of management science/operations research: building models that attempt to describe the world as it was, as it is, and as it will be.

World Englishes, 2020
AbstractWorld Englishes (WE) research has been invested in getting to grips with the diversity of different Englishes and in making sense of their structural properties. The first research strand led to a proliferation of theoretical models, the second to comparative research relying increasingly on sophisticated statistical modelling.

1996
When looking at relationships between two quantities, we are often interested in fitting a mathematical function to describe this relationship. Statisticians call these functions models. This activity uses data on levels of carbon dioxide in the atmosphere at a site in Hawaii to illustrate fitting a model to data.

Metaphilosophy, 2013
AbstractMichael Dummett famously maintained that analytic philosophy was simply philosophy that followed Frege in treating the philosophy of language as the basis for all other philosophy (1978, 441). But one important insight to emerge from computer science is how difficult it is to animate the linguistic artifacts that the analysis of thought ...

Model Evaluation Guidelines for Systematic Quantification of Accuracy in Watershed Simulations
, 2007Watershed models are powerful tools for simulating the effect of watershed processes and management on soil and water resources. However, no comprehensive guidance is available to facilitate model evaluation in terms of the accuracy of simulated data ...

The job demands-resources model : state of the art
, 2007Purpose – The purpose of this paper is to give a state‐of‐the art overview of the Job Demands‐Resources (JD‐R) modelDesign/methodology/approach – The strengths and weaknesses of the demand‐control model and the effort‐reward imbalance model regarding ...

This study evaluated the sensitivity of maximum likelihood (ML)-, generalized least squares (GLS)-, and asymptotic distribution-free (ADF)-based fit indices to model misspecification, under conditions that varied sample size and distribution.

Caries Research, 2015
Developing experimental models to understand dental caries has been the theme in our research group. Our first, the pH-cycling model, was developed to investigate the chemical reactions in enamel or dentine, which lead to dental caries. It aimed to leverage our understanding of the fluoride mode of action and was also utilized for the formulation of ...
