A.J. Heppenstall et al. (eds.), Agent-Based Models of Geographical Systems, DOI 10.1007/978-90-481-8927-4_17, © Springer Science+Business Media B.V. 2012 Abstract Designing, formulating, and communicating agent-based models (ABMs) poses unique challenges, especially how to choose the right level of c mplexity and how to describe – and, even, think about – a model in a way that captures both its...

We start from the Klaus Julisch’s (2008) IT compliance problem definition and make an attempt to formulate the enterprise architecture compliance problem (EACP). The challenging issues comprise the complexity of the law phenomenon, compliance frameworks and methodologies to check EA for noncompliance with laws and regulations. We hold that a compliance methodology should take into account “shar...

We discuss issues of problem formulation for algorithms in real algebraic geometry, focussing on quantifier elimination by cylindrical algebraic decomposition. We recall how the variable ordering used can have a profound effect on both performance and output and summarise what may be done to assist with this choice. We then survey other questions of problem formulation and algorithm optimisatio...

The offence risk posed by individuals who are arrested, but where subsequently no charge or caution is administered, has been used as an argument for justifying the retention of such individuals’ DNA and identification profiles. Here we consider the UK Home Office arrest-to-arrest data analysis, and find it to have limited use in indicating risk of future offence. In doing so, we consider the a...

background & aim: the plants of the greenhouse have been affected by infestation of the pest trialeurodes vaporariorum, called greenhouse whitefly, which markedly reduced production. synthetic insecticides have been widely developed and, their extensive use has brought about disadvantages, like environmental disturbance, pest resistance, lethal effects on non target organisms and toxicity t...

Introduction: Medical tourism is the travel of patients to outside the area of life to benefit from hospitals and medical services or some particular treatment or periodic test of physical conditions. This study has been done with the purpose of formulating a strategic plan of medical tourism development of Ahwaz city. Methods: The method of this research...

It is argued that in order to tackle a complex problem domain the first thing to do is to construct a well-structured problem formulation, i.e. a "representation". Representations are analysed as systems of distinctions, hierarchically organized towards securing the survival of an agent with respect to his situation. A preliminary variation-selection model is proposed for the generation of new ...

Meta-analysis involves combining summary information from related but independent studies. The objectives of a meta-analysis include increasing power to detect an overall treatment effect, estimation of the degree of benefit associated with a particular study treatment, assessment of the amount of variability between studies, or identification of study characteristics associated with particular...
