A Quantitative and Spatial Model of Escalation
… in the literature by developing a quantitative, spatial, process-based model of escalation which accounts for the possibility of misperception between actors. The model forms the basis for computer simulations of conflict between two adversaries which, in turn, facilitates the comparison of …

Automated cartographic generalization with a triangulated spatial model
… two-dimensional plenum that stores important spatial relationships such as "enclosed", "adjacent" and "between" explicitly. This simplicial data structure (SDS), as it is called, can be used directly to perform several types of operations necessary for automatic generalization, for example, …

Empirical Analyses of a Spatial Model of Voter Preferences
To properly analyze the advantages and disadvantages of voting rules, and how well the outcomes that they yield reflect voters' preferences, one needs very large data sets, since paradoxes that occur very rarely may have large impacts. Since such amounts of election data are currently unavailable, …

Predicting Northern Goshawk Dynamics Using an Individual-based Spatial Model
… Previous studies have suggested that a model integrating goshawk population demographics, habitat availability, and territoriality would have the ability to predict population dynamics including goshawk locations, population size, and population viability. An individual-based spatial …

Some multivariate problems of a spatial model of voting under majority rule
… we specify the mathematical foundation for a spatial model of voting under majority rule, and, building upon that foundation, we make three contributions to the formal theory of public choice. First, we formulate a spatial model in which voters are heterogeneous both with respect to their most …

Electric vehicle charging infrastructure deployment : policy analysis using a dynamic behavioral spatial model
… companies involved through a dynamic behavioral spatial model to draw policy recommendations for the roles of the government and the private sector in vehicle electrification. Because of the low cost of electricity and high costs of charging infrastructure capital, it will be difficult for EVSE …

The development of semantic memory : a spatial model of animal concepts in schoolchildren, novices and experts
… compared in order to examine the validity of a spatial model of conceptual development in schoolchildren.

Using a spatial model of geodiversity to guide conservation within mountains at the pan-tropical-scale.
… empirical work suggests that a resource based model of geodiversity may be a useful proxy for biodiversity within tropical mountains and could provide a valuable conservation planning tool. Here, geodiversity is defined as variation in overall resource availability, along with spatial and …

Managing the transition toward self-sustaining alternative fuel vehicle markets : policy analysis using a dynamic behavioral spatial model
… points. A broad-boundary, behavioral, dynamic model with explicit spatial structure was previously developed to represent the most important AFV transition barriers. Using California as an illustrative testing region, the model simulates the spatial diffusion of entrant vehicle/fuel technology …

The assessment of change in rural landscape and the analysis of the driving forces. Proposal of a spatial model for the rural built environment
… the rural built environment using a statistical spatial model implemented through GIS techniques. It is well known that the study of landscape changes is essential for a conscious decision making in land planning. From a bibliography review results a general lack of studies dealing with the …

A tripartite study on Bayesian estimation of photosynthetically active radiation, impacts of future climate, and adaptation strategies on crop production: a spatial model framework for the Eastern Kansas River Basin
… have relied on point-scale process-based crop modeling analysis to generalize regional insights. However, a comprehensive outlook to provide specific solutions and insights into climate change impacts and adaptation options will require a spatially explicit approach, treating each field in the …

Decentralized state-space controller design of a large PHWR
… described with sufficient accuracy using a nodal model, like the spatial model of a 540 MWe large Pressurized Heavy Water Reactor (PHWR). This model divides the reactor into divisions or nodes to create a spatial model in order to control the xenon induced oscillations that occur in PHWRs. …

Modelling Three-dimensional Fields in Geoscience with the Voronoi Diagram and its Dual
… are often not man-made objects, but rather the spatial distribution of three-dimensional continuous geographical phenomena such as the salinity of a body of water, the humidity of the air or the percentage of gold in the rock (phenomena that tend to change over time). These are referred to as …

Probabilistic Models For Population Dynamics
… particle systems that serve as probabilistic models for population dynamics are studied in this work. The quadratic contact process is a stochastic spatial model for a population in which each individual has two parents and the dynamics are governed by random birth and death rates and an …

Extra-Sovereign Institutions; The Ties That Bind
… on a basis of proximity, suggesting a spatial model of regional integration. However, a deeper investigation of the motivations and factors that lead to the creation of these institutions show this is not the case. In considering regional integration movements, this study establishes …

The township concept in modern South Africa
… space and society and the extent to which spatial solutions could resolve socio-economic problems. It is at this point those urban discourses, from urban administration to physical planning, met with the apartheid project for Separate Development. The intellectual construction of a "tribal" …

Integrative Research in the Sociology and Ecology of Outdoor Recreation
… examined integration of soundscape and hiker spatial modeling. GPS data were used to generate a spatial model of hiker travel, soundscape modeling software calibrated with field data was used to generate a spatial model of sound, and the models were integrated in a geographic information …

Market power and transportation price formation: Theory and an application to the captive shipper problem
We develop a spatial model of bulk commodity transportation price formation. The spatial transportation price model is first developed for the monopolist carrier. Then the model is extended to quantity-setting and price-setting duopolist carriers under incomplete cross-hauling. Measures developed …
