Spatial effects and experience through reflectivity
… light construction, and perceptions of different spatial relationships and has a long history from modernism to the present. This thesis proposes to question received notions of glass as a transparent material and instead focus on its possibilities as a reflective material. The thesis is an …

Systems of chemical reactions in biology : dynamics, stochasticity, spatial effects and model reduction
… systems of chemical reactions where stochastic effects are relevant, and simplifies the standard models. We develop an approximate model for the time-evolution of the average concentrations and their variances and covariances in systems with and without spatial gradients. We also describe a …

The probability of nonconvergence and its spatial effects in the hard red winter wheat market
… examine the efficacy of the VSR and show the spatial effects of nonconvergence in the HRW wheat market throughout the state of Kansas. A dataset consisting of daily spot prices at 91 grain handling facilities across Kansas, daily closing futures prices, and daily three-month London Interbank …

A Multivalent Ligand Display System with Plant Viruses: A Novel Approach Towards Studying Spatial Effects of Cell Adhesion Ligands
… Arg-Gly-Asp, for cell adhesion) with different spatial densities with nanometer precision. Furthermore, given the immense diversity of viruses and virus-like particles, one could find an ideal model that is well-suited to generate a variety of spatial arrangements of ligands. Herein we present …

CONGESTION CHARGE AND REMOTE WORKING: POLICY INSIGHTS FROM SPATIAL EQUILIBRIUM MODELS
… thesis investigates key topics related to 1) the spatial effects of congestion charge (single- vs multi-city, with or without travel time saving) and various tax revenue redistribution schemes (even vs place-based distribution); 2) the spatial effects of remote working due to the uncertainty of …

Spatial-Longitudinal Bent-Cable Model with an Application to Atmospheric CFC Data
Spatial data (also called georeferenced data) arise in a wide range of scientific studies, including geography, agriculture, criminology, geology, urban and regional economics. The underlying spatial effects – the measurement error caused by any spatial pattern embedded in data – may affect both …

Bayesian analysis of spatial and survival models with applications of computation techniques
… (CAR) prior is used for the model to capture spatial effects. Markov chain Monte Carlo (MCMC) methods are used in the sampling. The Ancillary-Sufficient Interweaving Strategy (ASIS) is applied to improve the performance for some parameters. The convergence of some of the parameters improved …

Structure and Structural Change in China's Economy
… employed a non-parametric method to examine spatial effects modeling the regional income disparity pattern in China. The main findings are that with the enlarging regional income disparity between the core region (coast) and the periphery region (west), China's regional income distribution …

Cape Town Airbnb price prediction: an exploration of spatial statistic and machine learning methods
… Using data from InsideAirbnb, traditional, spatial and machine learning models are compared and contrasted. The Cape Town Airbnb market has significant spatial correlation and heterogeneity, and traditional models such as OLS regression do not account for this spatial dependence, however, it …

Shared-component model with application to mapping gender specific pattern in HIV testing and condom use in Namibia
… study was to examine gender-specific and shared spatial variation in HIV testing and condom use in Namibia for targeted health promotion interventions. The study used data from the Namibia Demographic and Health Survey (NDHS) carried out between 2006 and 2007. Bayesian hierarchical spatial …

The Spatiality of Housing Price Risk and Return in The Greater Toronto Area
… and some of these studies control for its spatial structure. There is a deficiency, however, in studies that examine the spatial relationship of risk at varying spatial scales and even fewer that do so in a Canadian context. The current study addresses these deficiencies by examining …

Food Environment and Childhood Obesity
… panel estimation, it was found that the fixed effects model fit the data best. Results indicate that an additional supermarket within a one-mile radial of the census neighborhood block center will bring down childhood obesity prevalence by 0.58 percent, whereas associations between densities of …

Spatial Econometrics Revisited: A Case Study of Land Values in Roanoke County
… literature demonstrates the possibility of spatial autocorrelation in land value models. A number of objections regarding the methodology followed in those empirical studies have been raised. This thesis examines three propositions. The first proposition states that there is spatial …

Three essays on the spatial analysis of sustainable dairy farming in New Zealand
… the impact of farmer choice on the environment. Spatial spillover effects, which are considered as important issues at either the regional level or farm-level decision-making, are addressed in all three essays. As the New Zealand dairy industry faces the challenge of increasing productivity and …

Essays on Regional Recessions, Spatial Interactions and Forecasting
… that enables applied researchers to quantify spatial interactions from panel data where variables exhibit recurrent abrupt shifts in behavior. In empirical macroeconomics, omitting spatial effects is restrictive in many contexts because the units of analysis are regions, the characteristics of …

Development, characterization, and application of a charged particle microbeam for radiobiological research
… level, particularly in the area of temporal and spatial effects of radiation on in vitro systems. An accelerator-based 750 keV proton source was characterized and integrated into a laboratory-scale device that includes a deflection/gating system, single-particle detection system, imaging and …

Transformative infrastructures: retrofitting the apartheid city
… terms of its social, economic and topographical effects rather than purely on functional terms, the project proposes a method of intervention that transforms the city by ameliorating the negative spaces of existing infrastructure, bridges spatial divisions, and provides physical and social …

The myth of the single mode man : how the mobility pass better meets actual travel demand
… machines that increasingly seek to mitigate the effects of that growth caused by commensurate increases in auto usage, including congestion and emissions. Employers have an interest in reducing the costs of providing parking, and reducing local congestion, in part to attract and retain employees. …
