▼ Climate change and competing land use needs continue to drive change in forest management in British Columbia. Balancing these needs in the face of a diminishing timber harvesting land base presents ongoing challenges for forest managers. This is especially true for small, area based tenures. Overlapping or competing land use values, such as Species at Risk habitat, can have a disproportionate effect on their management and viability. While government and industry processes exist for optimizing competing objectives while still managing for timber, they are largely tailored at a scale and magnitude suited to major industry and not small area-based tenures. This case study explores the potential of adapting one such process, the Stewardship/Timber Harvesting Landbase (THLB) Stabilization Pilot process, to small tenures using spatial modelling. Focusing on a Woodlot Licence in the Fraser Valley, predictive habitat models were developed for two Species at Risk using readily available software and data. Although spatial correlation of model results with known habitat reserves was inconclusive, models show promise as cost-effective tools for small tenure managers to visualize ecosystem values and their management implications.

▼ This study investigates the economic problem of recent booming farmland values. An income capitalization
model is estimated to conduct farmland valuations using state-level data from 1980 to 2011. Explanatory variables include expected market returns, government payments, production risk, urban influence, interest rates, and ethanol production scale.
Spatial models are introduced to control for
spatial dependencies on farmland values, and multiple tests are conducted to explore the most appropriate
model for farmland valuation. Furthermore, the thesis offered suggestions for future researches and to provide a proposal in forecasting future farmland values according to the changes in the determining factors.

▼ Spatial heterogeneity is an important characteristic
of large-scale composting, however, only a few spatial models for
composting exist to date. In this thesis, a novel spatial model for
composting is developed. The model is applicable for any one-,
two-, or three-dimensional pile geometry. It accounts for the
consumption of organic matter and therefore considers the whole
composting process from the beginning to the end of decomposition,
gives a realistic prediction of the buoyant air flow patterns,
incorporates the cooling by passing air, and includes the effects
of compaction. The model is validated using existing data from a
series of in-vessel composting experiments, and then utilized to
simulate windrow composting. Effects of the windrow size variation
are explored and it is demonstrated that decomposition speed
increases as the pile height increases, however, for large piles
this increase becomes smaller as oxygen concentration limitations
become significant. Air floor technology is simulated,
demonstrating a significant decrease in decomposition time even for
passive aeration. The developed model can be a useful tool in
process optimization and facility design.

▼ This dissertation contains three essays examining new
Bayesian econometric methodologies. The first develops a
heterogeneous
Spatial Autoregressive
Model by integrating a finite
mixture
model structure into the traditional homogeneous
specification. The second essay builds upon the first by extending
this
Spatial Mixture
Model structure to the more general
Spatial
Durbin and
Spatial Durbin Error specifications. Additionally, this
essay covers the interpretation of these new
model specifications.
Finally, the third essay develops a predictive based
model
selection process by integrating cross-validation algorithms into
standard Bayesian sampling methods with a focus on explicit
out-of-sample prediction. 1.0.1 Embracing Heterogeneity: The
Spatial Autoregressive Mixture ModelIn this essay, a mixture
distribution
model is extended to include
spatial dependence of the
autoregressive type. The resulting
model nests both
spatial
heterogeneity and
spatial dependence as special cases. A data
generation process is outlined that incorporates both a finite
mixture of normal distributions and
spatial dependence. Whether
group assignment is completely random by nature or displays some
locational "pattern", the proposed
spatial-mix estimation procedure
is always able to recover the true parameters. As an illustration,
a basic hedonic price
model is investigated that includes
sub-groups of data with heterogeneous coefficients in addition to
spatially clustered elements. 1.0.2
Spatial Durbin Mixture
ModelsThis essay extends the finite mixture
model structure to
include
Spatial Durbin and
Spatial Durbin Error
model
specifications. The partial derivatives of this heterogeneous
spatial model structure are shown to differ between border and
interior agents; the designation of which is based on group
assignment and first order neighbor designation. As an
illustration, individual income based on data from the Panel Study
of Income Dynamics (PSID) is examined using the
Spatial Durbin
Mixture
Model specification.Results from the
model indicate that
returns to income from education are heterogeneous with some agents
receiving negative returns on each additional year of human capital
development. 1.0.3 Bayesian Predictive
Model Selection using
Cross-ValidationIn this essay, leave-one-out cross-validation is
combined with Bayesian sampling and inference to develop a new
model selection process. This process relies both upon standard
hypothesis testing, and, in the absence of sufficient evidence,
Ockham's Razor to selection a
model from a competing set. It is
shown that this process outperforms many of the criteria used in
empirical work both by selected the true process more often, and
selecting a smaller set of models overall.

▼ This paper tests the regional convergence of GDP per capita across 27 Chinese provinces during the period 1961-2018 with considering the spatial interactions. First, this study only finds a slight divergence over the entire period. Furthermore, the flowing research of this paper divides the overall time span into three sub-period based on two major economic policies, namely the “Open Door Policy” and the “Western Development Strategy”. During the period 1961-1977, which is regarded as a phase of planned economy, this paper finds the evidence of regional convergence. Moreover, the results indicate a slight divergence in GDP per capita during the period 1978-1999, proving that the “Open Door Policy” intensifies regional gaps of China. Finally, this study verifies the role of the “Western Development Strategy” in reducing regional differences since a convergence is found during the last period 2000-2018. The outcomes of this research reveal a strong relationship between economic policies and regional convergence, and thus the transition of policies should be considered when investigating the economic convergence. Furthermore, this research also verifies the importance of spatial effects in the process of convergence or divergence. The results are likely to be biased if the spatial dependence is neglected.

▼ This study was conducted to
model the extent of eelgrass habitat in Humboldt Bay, California through physical surveys of the maximum depths and upper limits of growth in conjunction with recently acquired high-resolution bathymetry data and supplemental imagery. A combination of chronic turbidity, frequent coastal stratus, and wind-waves, make Humboldt Bay a challenging environment to assess subtidal eelgrass (Zostera marina) habitat from remotely-sensed imagery. Additionally, eelgrass and green algae overlap extensively in shallow intertidal areas, confounding efforts to distinguish between habitat types from imagery alone. A relative exposure index (REI) was developed to identify areas of eelgrass habitat that may be prone to disturbance from wind-waves. Approximately 2200 hectares of eelgrass habitat were identified. Accuracy was assessed at 91% for modeled eelgrass habitat in South Humboldt Bay based on a comparison with hyperspectral imagery captured in October, 2004. Modeling the extent of eelgrass habitat represents an important step towards understanding the extent to which future restoration or mitigation may be possible in Humboldt Bay.

▼ The first essay provides an introduction into the literature of spatial competition models and studies their predictions on the degree of horizontal product differentiation. For this purpose a selection of articles, mainly from the game theoretical strand of the literature, is re-examined in which each model extends and modifies basic parameters of the original model of Hotelling (1929).
The literature survey emphasizes that markets consisting of intersecting roads represent a particular fruitful subject of future research. The nature of competition in this market setting is different compared to the linear city exemplified by the importance of asymmetrical location patterns. Consequently, the strategic interaction, firms' profit-maximizing behavior and potential equilibrium outcomes under sequential entry in a market with intersecting roads remain to be an interesting field
to study.
The second essay addresses this research gap and based on the work of Anderson (1987) studies a two-stage market entry game in a spatially extended Hotelling's
duopoly. Particularly, the effect of a demand dependent centrality bonus Z distributed in the middle of the linear city is examined on the reaction functions of
an incumbent firm and the strategic entry decision of an entrant firm. A solution is provided for an entry accommodating scenario where both players optimize profits
over their strategic variables and the center Z is taken by the incumbent firm. The results further suggest that the entrant is not capable of capturing Z. In addition,
the model implies a lower degree of product differentiation as Z increases. A comparison with the literature shows that these results are well in line with Anderson's model for Z = 0. In a business strategy view the outcome supports the
thesis of Gelman & Salop (1983), coined by the term 'judo economics', since the entrant earns highest profits by committing himself to a distant location and charging
a comparatively lower price than the incumbent.
The third essay analyzes the price distribution of diesel in the Austrian retail gasoline market and tests predictions of the impact of the fraction of informed and uninformed consumers on the mean price and price variance. Further, introducing two measures of spatial competition, the relation of local competition between stations and the
mean and variance are examined. In a pooled cross-section analysis a two step approach is followed. Initially, price levels are estimated with respect to the influence of competition, search costs, stations' location and further station-specific characteristics. Controlling for these observable price characteristics, the residuals are used in the second step to investigate the behavior of the price variance. In addition to OLS, to account for spatial spillover effects a Spatial Error Model (SEM) is applied to estimate the price function. Additionally, tests on model specification and robustness checks using different weighting
matrices, search cost proxies and dispersion measures are carried out.…

▼ Describing structures of geospatial objects as models is essential for understanding
geographic processes. Efforts to develop such models started from decades ago but a
model for 3D
spatial-temporal (3D space plus 1D time) objects has not been well
formulated. This dissertation describes the formalization of a
spatial-temporal data
model
for managing 3D
spatial-temporal objects. This
model extends the
spatial-temporal
Object-Oriented
model by incorporating a behavioral description to the definition of the
spatial-temporal objects to better characterize the dynamics of these objects. Besides,
spatial-temporal rules and conditions, which are expressed as constraints, are integrated
as important components of the
model. These rules and conditions serve as the
foundations of maintaining data integrity and enabling complex
spatial-temporal queries.
A set of constraints related to the
spatial-temporal characteristics of 3D
spatial-temporal
objects were identified and defined. The conceptual
model served as the theoretical basis towards the building of a
Geographic Information System (GIS) for managing 3D
spatial-temporal objects. Based
on the conceptual
model, a prototype system was developed that provides interactive data
management and query functions for 3D
spatial-temporal objects. A subset of spatialtemporal
constraints identified in the conceptual
model were captured and formalized
through extended 3D computational geometry algorithms to ensure data integrity and
facilitate
spatial-temporal queries. Using the dynamic repartitioning of airspace sectors as
a case study, this research shows that the proposed framework is effective to solve
problems involving 3D
spatial-temporal objects.

▼ Bayesian methods are widely adopted nowadays in statistical analysis. It is especially useful for the statistical inference of complex models or hierarchical models, for which the frequentist methods are usually difficult to be applied. Though as a decision-making theory, often there are debates on the prior choices, the Bayesian methods benefits from its computational feasibility, with a variety of Markov chain Monte Carlo algorithms available. Three topics are studied using Bayesian methods. First, the competing risks
model for masked failure data is investigated, which suffers from an identification problem. The identification problem and possible solutions are discussed and a Bayesian framework is used for the complex
model. The other two topics are relevant, focusing on the lattice system and areal data. For a specific lattice system called generative star-shape
model, objective priors are developed in order to achieve better estimations. The last topic is modeling areal data from a special project. A hierarchical
model is developed for modeling the bounded outcomes with
spatial variation and a Bayesian analysis is performed.

DISCRETE CHOICE UNDER SPATIAL DEPENDENCE AND A MODEL OF INTERDEPENDENT PATENT RENEWALS.

▼ In my thesis I develop a theoretical
model of interdependent choices and an estimation strategy which I apply to
model patent renewal. The
model and the estimation are not confined to my application, but rather can have other applications in which firms or people are making strategic and simultaneous decisions. Chapter 1 is the introduction which contains a brief description of the structure of the thesis.
Chapter 2 provides a literature review of studies that have focused on
spatial dependence with discrete choice dependent variables; recent contributions include Pinkse and Slade (1998), LeSage (2000), Kelejian and Prucha (2001), Beron and Vijverberg (2004), and Wang et al. (2009). A major difficulty in the estimation of spatially dependent discrete choice models is computational intensity.
Chapter 3 is a Monte Carlo study that investigates the small sample properties of an estimator for spatially dependent discrete choice models which is computationally simple. The analogue of a linear probability can be formulated as a
spatial autoregressive Cliff and Ord (1973, 1981)-type
model. The sets of Monte Carlo experiments show that the parameters of the
model can be estimated without bias using a
spatial 2SLS estimator.
Chapter 4 is a study is on the determinants of patent renewal, using US patents for Computer Hardware and Software granted between 1994 and 1997. Patent protection is important in that it encourages innovation by allowing firms to rely on patents to appropriate the returns to their R&D efforts. Returns to patents are modeled to depend on the firm's willingness to pay the patent renewal fees by, e.g., Harhoff et al. (2003), Serrano (2006), and Bessen (2008, 2009), and typically ignored potential interdependences in the decision making. Liu et al. (2008) showed that patent renewal was more likely if the patent was part of a firm's sequence of citing patents. I elaborate on their result and formulate a
model in which the decision to renew a patent is dependent on the decisions of other firms to renew technologically similar patents. The theoretical
model implies for the probability to renew a patent to depend on the probabilities to renew other patents, where the extent of interdependence is modeled based on a measure of similarity for patents. By making use of the estimation strategy from Chapter 3, I find that indeed the decision to renew a patent is dependent on the decision to renew related patents. Results in the literature which ignored this interdependence may hence suffer from specification biases. One plausible explanation for the interdependence I find is defensive patenting in the form of patent fencing, patent blocking and patent thickets. In the latter case, litigation and negotiation can impose high costs to society and their anticipation can lead to a hold up problem, which could deter investment in R&D.

▼ The systematic approach had been recognized as one of the most effective tools for Marine Protected Area (MPA) planning. But MPA planning still exist many uncertainty in the real world, ex. the effect of MPA planning and the support of stakeholders or neighbors. In recent years, there are many researches using
Spatial Optimization
Model for MPA planning, but only can provide âcurrent optimal resultsâ for decision marker. Decision marker couldnât know the real effectiveness of MPA in the future, and stakeholders also couldnât know their benefit would be affected or not. The Adaptive Management is a good management way for MPA, it can help decision marker deal with the uncertainty of environment and ecology in MPA management for sustainable development. But traditional Adaptive Management have to collect long term observer data and the feedback from MPA in order to improve MPA management. Therefore, the Adaptive Management is difficult to implement. In this study, we integrate the
Spatial Dynamics
Model for Ecosystem and the
Spatial Optimization
Model as an Integrative
Spatial Optimization and Dynamic
Model for MPA Planning. This Integrative
model not only can generate the optimal
spatial MPA allocation for user, but also can provide the social economic and ecological assessment for MPA establish. The decision marker and the stakeholders can using these assessments from our
model to discuss witch MPA planning could share a common interest for sustainment. In the result, we demonstrate two integrate methods and compare the effectiveness in different MPA

▼ The populations in the western United States have increased significantly over the last few decades resulting in increased development pressures on undeveloped and pristine lands. Population growth and increased human activities have also changed the overall ecosystems more rapidly and extensively in recent years than in the past, emphasizing the need for protecting natural land and ecosystems. This dissertation conducts analyses to highlight the importance of protected areas and wildlife habitat. Chapter 1 explores the use of Poisson and negative binomial regression models to examine winter habitat use by mountain goats in the Kenai Mountains of South-Central Alaska. Using GPS collared locations data, these models produce parameter estimates similar to discrete choice models, popular in resource selection studies, but with less computational complexity. The potential serial (or
spatial) correlations present in the data are controlled for by incorporating
spatial effects in a Gaussian conditional autoregressive framework. The results support the existing literature on mountain goat habitat use with most of the terrain features statistically significant across individual goat models. The distance to the nearest escape terrain is found to be the most consistent and highly significant determinant of goat habitat selection, where individual goats tend to increase the number of visits by 37.5 to 71.6 percent more to a particular location that is 100m closer to escape terrain. The statistical significance of
spatial parameter highlights the importance of neighborhood effects in habitat selection by mountain goats. Chapter 2 seeks to achieve two objectives. First, using regression based test of equivalence, the predicted habitat use by mountain goats are compared for two different sources of data. For mountain goats, the findings suggest that the predicted habitat uses from GPS collar and aerially surveyed locations are equivalent. Second, using the aerially surveyed goat locations data, the Bayesian inference techniques with respect to negative binomial regressions are employed to explore the effects of winter recreation on mountain goat habitat selection. In addition to the landscape features, the
model comparison based on Bayes factor suggests that human recreation is an important factor affecting goats habitat use. Goats tend to avoid areas with higher human recreational activities represented by ski-tracks, and hiking trails; increase in the ski-tracks area by one square km within a buffer of 5 km reduces goat count by approximately 2.5 percent at a particular geographic location. This highlights the potential conflict between human recreation and winter habitat and provides an input into policy discussions on conservation of mountain goat habitat. Chapter 3 of this dissertation analyzes the statistical properties of estimated parameters in the hedonic studies with special reference to the distance variables used to represent the proximity to environmental amenities or dis-amenities. Using Monte Carlo simulations, the…

▼ Mestrado em Gestão e Avaliação Imobiliária
Um dos principais desafios para os proprietários de centros comerciais é como atrair visitantes aos seus centros. Esta tese examina os determinantes do número de visitantes de um centro comercial na Área Metropolitana de Lisboa através de um modelo de spatial lag. Esta metodologia tem sido raramente utilizada em estudos sobre a atratividade dos centros comerciais e demonstra-se que é melhor face a uma estimativa com um modelo de estimação OLS. A análise também mostra que a presença de uma âncora alimentar e a proximidade a uma estação de metro são determinantes importantes na atração de visitantes a um centro comercial. No geral, os resultados também indicam que, no caso da Área Metropolitana de Lisboa, os centros comerciais competem uns com os outros, mas há também efeitos positivos de aglomeração.
One of the main challenges for mall owners is how to attract shoppers to patronize their malls. This thesis examines the determinants of the number of visitors to a shopping center in the Lisbon’s Metropolitan Area using a spatial lag model. This methodology has been rarely used in studies exploring shopping center attractiveness and is shown to improve upon standard OLS estimation of cross-sectional data. The analysis also shows that housing a supermarket and proximity to a metro station are important determinants of shopping center patronage. Overall, the results also indicate that in the case of the Lisbon Metro Area, shopping centers do compete with each other, but there are also positive agglomeration effects.

▼ This dissertation illustrates how the use of
spatial economics, as opposed to non-
spatial methods, can enrich economic research related to natural resources decision-making. This research encompasses three distinct, but complementary, papers, based on two datasets that vary in richness and scale, and one data-driven
model that will detail how data will need to be collected to inform natural resource infrastructure projects in a developing economy. The first essay uses cutting-edge
spatial econometric techniques to evaluate the location decisions of private outdoor recreation providers. Here, I find clustering of outdoor recreation opportunities and that private providers are attracted to areas with existing public outdoor recreation opportunities when making their own location decisions. The second essay focuses on a specific form of privately provided outdoor recreation, agritourism, and again finds that the more existing outdoor recreation, the more agritourism trips will be taken. The second essay uses a hurdle travel cost
model and focuses on the demanders, as opposed to the suppliers, of private outdoor recreation. The findings reveal that agritourists gain substantial consumer surplus (with averages ranging from 93 to 465) from their trip, and that the
model treatment of multi-destination agritourists impacts the estimated consumer surplus. The first two papers use author-created outdoor recreation measures that are introduced in this dissertation. These measures were created to complement the USDA-Economic Research Service Natural Amenities Index, with input from the creators of the Natural Amenities Index, and have potential to be used in many natural resource and economic development studies as the Natural Amenities Index has been. In contrast to the other essays, the third essay recognizes that
spatial relationships can be important in evaluating an economic question, even when dense
spatial datasets are not available. The study uses an Equilibrium Displacement
Model to evaluate water management and storage policies for a canal system in Afghanistan, a country where war and poverty have damaged infrastructure and made it difficult to collect accurate data. Producers'
spatial location on the canal is of key importance to understanding their decisions and the failure to account for these
spatial relationships could lead to misinformed policy decisions. The Equilibrium Displacement
Model results show that water management and storage policies have different impacts on producers based on their
spatial location on the canal. Through the use of three very different models, this dissertation illustrates the importance of incorporating
spatial impacts when evaluating policies related to natural resources.

▼ Modern society has become ocular-centric as a result of technological development making the production and distribution of images easier than ever before. This ocular bias extends to architecture. Rather than resisting the increasingly ocular-centric nature of our social-media driven culture, this research aims to find new methods for designing space which incorporate a tactile process. This process simultaneously focuses on the creation of marketable perspectives. Through this research I advocate for tactility in the design process to evoke
spatial awareness of the image.
This research portfolio operates through a design-led research methodology where knowledge is uncovered by designing. Hundreds of models were produced and critically reflected upon in terms of both their process and outcome. The research culminates with the development of a design process centred on using architectural models as design tools. Referred to as devices, these models are
spatial systems that are able to be manipulated by hand to alter the composition of a perspective view. Although focusing on the image, the physicality of the devices implicate
spatial awareness in the design process ensuring the design is considered in both two and three dimensions.
A design for the proposed Kapiti Island Biosecurity Gateway Centre formed an architectual testing ground which was used to evalute the design process developed in this research. Influenced by the design process the architecture itself also became an optical device. The resulting design controls and composes views through concealing, revealing, superimposing, aligning and framing particular elements. The final outcome provides visitors with a choreographed journey of highly considered perspective compositions

▼ Nitrous oxide is a major greenhouse gas emission. The aim of this research was to develop and apply statistical models to characterize the complex spatial and temporal variation in nitrous oxide emissions from soils under different land use conditions. This is critical when developing site-specific management plans to reduce nitrous oxide emissions. These studies can improve predictions and increase our understanding of environmental factors that influence nitrous oxide emissions. They also help to identify areas for future research, which can further improve the prediction of nitrous oxide in practice.

▼ Africanized honey bees (AHB) are a hybrid between African and European honey bees (EHB). Compared to the EHB, AHB exhibit more intense, defensive behaviors but nevertheless provide the same important ecosystem service – pollination. AHB have been found in Tucson, AZ. since 1993. It is important to understand the population ecology of AHB for several reasons. Most directly, the behavioral traits retained from African bees present public safety and health risk. AHB are easily agitated; even slight disturbances (e.g., human movements) can provoke attacks. Several hybridized bee traits (e.g., higher colony growth rates, reproduction at a smaller colony size, nesting in a wider range of cavity materials, etc.) also make them more adapted to urban landscapes. The overlap of habitats and resource-using of AHB with human significantly raise the risk of stinging incidents, especially in the areas of bee aggregation. Although the presence of AHB in urban environments may present a public safety and health risk, they do contribute to urban ecosystems substantially through pollination. The fact that AHB is a part of the urban ecosystem suggests a need for a better understanding of the relationship among climate factors, urban landscape characteristics, and AHB population dynamics.
The goal of my dissertation was to understand population dynamics of AHB in urban environments using removal records of AHB colonies in water meter boxes. I have demonstrated useful methods and repeatable procedures to process, extract, and synthesize water meter box data which were not collected or sampled specifically for any ecological research. I also examined the spatio-temporal distributions of AHB colony removals in water meter boxes, and evaluated the effects of variations of temperature and precipitation on observed patterns. Then, I investigated the linkage between
spatial patterns of AHB colonies and urban landscape characteristics by evaluating densities of water meter boxes, AHB colony abundance, and colony occupancy among different land cover/land use types. Lastly, a conceptual
model and quantitative models were developed to illustrate AHB population dynamics, particularly and the interactions among water meter boxes, alternative cavities, and honey bee colonies.
Overall, the probabilities of AHB colonies selecting nesting sites can be influenced by: (1) the ratio of water meter boxes and alternative cavities; (2) the difference of vegetative attributes among locations associated with the preference of AHB in selecting new nesting sites. Seasonal variations of precipitation and temperature can affect the development and productivity of AHB population.

▼ This thesis focuses on statistical methods to calibrate complex computer models using high-dimensional
spatial data sets. This work is motivated by important research problems in climate science where such computer models are frequently used. Climate models play a central role in generating projections of future climate. An important source of uncertainty about future projections from these models is due to uncertainty about input parameters that are key drivers of the resulting hindcasts and projections. Climate
model calibration is a statistical framework for inferring the input parameters by combining information from climate
model runs and observational data. When the data are in the form of high-dimensional
spatial fields, climate
model emulation (approximation) and calibration can pose significant modeling and computational challenges. The goal of this research is to develop new approaches to computer
model calibration that are computationally efficient, accurate, and carefully account for uncertainties. The main contributions of this thesis are three-fold: (1) to develop a highly efficient reduced-dimensional climate
model calibration approach that enables the use of high-dimensional
spatial data; (2) to formulate a novel calibration method based on block composite likelihood and study the asymptotic properties of the resulting estimates for input parameters; and (3) to introduce a calibration framework that generalizes the existing method to the one-dimensional exponential family and formulate a reduced-dimensional approach that can efficiently handle the high-dimensional non-Gaussian
spatial data. Our methods provide insights about current and future climate. In our first application we make projections of the North Atlantic Meridional Overturning Circulation (AMOC), an ocean circulation that transports heat from low- to high-latitude areas in the Atlantic and contributes to the mild climate in Northern and Western Europe. AMOC changes are projected to impact human and natural systems. We demonstrate that utilizing information from high-dimensional
spatial data reduces parametric uncertainty and thus results in an AMOC projection with reduced uncertainties. In the second case study, we demonstrate an application of our approach for non-Gaussian
spatial data to calibration of a Greenland ice sheet
model and show that our approach can improve upon current methods for projections of sea level rise contributed by the Greenland ice sheet.

▼ Beijing experienced significant changes in its urban social spatial structure within last several decades. Economic growth, evolving urban planning policy and large-scale urban development have accelerated the pace of human displacement in
Beijing. By applying a spatial-temporal analysis to identify social-spatial structural change in Beijing over time, this study aims to elucidate the driving forces of the process, draw useful findings for future urban planning in Beijing, and shed light
on urban studies in other Chinese cities. Clustering analysis is performed to identify the spatial distribution pattern in Beijing in light of social-economic factors (migrant status, occupation and education level), as well as household and other
demographic attributes. The GWR model is then used to examine the relationship between population change and distribution of diverse social groups during 2000 and 2009. Data on recent social phenomena are captured by the model and provide implications
for planning and decision making, especially in light of new urban poverty and “social vulnerable groups.”

Despite recent methodological improvements and higher data availability, the
Climate Change (CC) and Armed Conflict (AC) studies are suffering from poor data
and inappropriate research designs (e.g., Incompatibilities of scale). This study fills
the gaps by taking the climate conflict analyses into a different scale (e.g., 55 km x
55 km sub-national cell/year) and uses high resolution Geo-referenced data sets. This
study presents the results from 10 years (1991-2000) of observations and a rigorous
modelling methodology to understand the effects of climate change on the conflict
occurrence in the Eastern Africa. The main objective of the study is to identify and
understand the conflict dynamics, verify the pattern of conflict distribution, possible
interaction between the conflict sites and the influence of climatic covariates of
conflict outbreak. We have found that if the climate related anomaly increases, the
probability of armed conflict outbreak also increases significantly. To identify the
effect of climate change on armed conflict we have modeled the relationship between
them, using different kinds of point process models and Spatial Autoregressive
(SAR) Lag models for both spatial and spatio-temporal cases. In modelling, we have
introduced one new climate indicator, termed as Weighted Anomaly Soil Water
Index (WASWI), which is a dimensionless measure of the relative severity of soil
water containment indicating in the form of surplus or deficit. In all the models the
coefficients of WASWI were found negative and to be significant, predicting armed
conflict at 0.05 level of significance for the whole period. The conflicts were found
to be clustered up to 200 kilometers and the local level negative relationship between
conflict and climate suggests that change in WASWI impacts changes in AC by -
0.1981 or -0.1657. We have also found that the conflict in the own cell associated to
a ( app. 0.7) increase in the probability of conflict occurances in the neighbouring
cell and also to a (app. 0.6) increase of the following years (spatio-temporal). So,
climate change indicators are a vital predictor of armed conflict and provides a
proper predictive framework for conflict expectation. This study also provides a
sound methodological framework for climate conflict research which encompasses
two big approaches, point process modelling and lattice approach with careful
modelling of spatial dependence, spatial and sptio-temporal autocorrelation, etc.

Protest in Europe where analyzed to foster an understanding of the distribution and
the behaviour of those during from 2000 to 2010 time frame.
The main object of this study is to discover if there is a relation between economic,
social and other variables available in Eurostat in order to discover a pattern in the
protests in Europe. For this purpose, least squared method and spatial point pattern
analysis method were applied in the R Software environment. The final output
indicates that variables can’t explain a cause-effect relation of protests due to tis
behaviour is complex and Europe is an inhomogeneous area. In the other hand, we
saw that protest tend to increase mostly when other protest have happened in the
past.
Protest location are scattered within the European megalopolis, and reveals attraction
to some capitals some hot spots patterns are observed. They are mostly located in
urban areas, close to the borders with other European countries. The resulting models
discovered that protest/events distributions do not imitate an inhomogeneous Poisson
process and thus we tried to model the behaviour describing special interaction
between locations of protests.
The best interaction model was chosen by computing different distances. We
analyzed the whole Europe area and due a strong influence of United Kingdom we
computed the same model to Germany, France, United Kingdom and Spain. Finally,
a step further spatial-temporal analysis was taken only for Spain.
This analysis is one of the first analyses set by the recently launched Global Database
of Events, Language, and Tone (GDELT), a big free online data base of over 250m
events and 300 categories including riots and protests codified from world news
sources.
After this analysis we recommend, further analysis should contain models that apply
border contagion including time.

▼ This thesis aims to increase our understanding of
mechanisms that influence larval dispersal in marine benthic
invertebrates, particularly in the absence of strong oceanographic
features (e.g. estuarine plumes, upwelling events, or markedly
different water masses). Laboratory experiments identified
behavioural mechanisms that regulate the vertical distribution of
larvae in response to thermal stratification, and field studies in
St. George’s Bay, Nova Scotia (NS), Canada, examined the
relationship between larval abundance and physical variables
(temperature, salinity, fluorescence, etc) and identified
mechanisms that regulate larval distributions in situ. In the
laboratory, I demonstrated that thermal stratification affects the
vertical distribution of larvae by acting as a barrier to
migration, or through temperature-dependent vertical swimming
velocities. I also developed a random walk based
model which
highlighted that the key to successfully simulating larval response
to temperature was 1) determining the temperature-dependent
distribution of vertical swimming velocities and 2) the temporal
autocorrelation in these velocities. In the field, the most
striking pattern was that the larval distributions for species with
similar swimming abilities were significantly correlated to one
another at all scales (0.5 to 40 km). This suggests a common
mechanism, related to larval swimming ability, which greatly
influences the horizontal larval distribution. I found that the
spatial scale of variability in larval distributions (~ 3 km)
matches that in both the environmental variables and of coherent
structures in current velocities (i.e. the tidal excursion).
Results from an aggregation-diffusion
model suggest that horizontal
larval swimming could not be responsible for the observed level of
aggregation in the larval horizontal distributions. I suggest that
these horizontal patterns are the result of 1) an aggregative
process (i.e. larvae swimming against a vertical current and
maintaining their vertical position) and 2) a diffusive process
which scales the aggregations to the scale of the coherent
structures in current velocity (i.e. tidal excursion). In
conclusion, this thesis increases our understanding of larval
behaviour and its effects on larval dispersal. The results will be
particularly useful to those who are interested in mechanisms
regulate population connectivity, particularly those using
bio-physical models to
model dispersal trajectories.

▼ Spatial analysis of species for which there is limited quantity of data, termed as the data-poor species, has been challenging due to limited information, especially lack of spatially explicit information. However, these species are frequently of high ecological, conservation and management interest. In this study, I used two empirical examples to demonstrate
spatial analysis for two kinds of data-poor species. One example was seabird bycatch from the U.S. Atlantic pelagic longline fishery, which focused on rare events/species for which data are generally characterized by a high percentage of zero observations. The other example was endangered white abalone off the California coast, which focused on endangered species whose data are very limited. With the seabird bycatch example, I adopted a
spatial filtering technique to incorporate
spatial patterns and to improve
model performance. The
model modified with
spatial filters showed superior performance over other candidate models. I also applied the geographically weighted approach to explore
spatial nonstationarity in seabird bycatch, i.e.,
spatial variation in the parameters that describe relationships between biological processes and environmental factors. Estimates of parameters exhibited high
spatial variation. With the white abalone example, I demonstrated the spatially explicit hierarchical demographic
model and conducted a risk assessment to evaluate the efficacy of hypothetical restoration strategies. The
model allowed for the Allee effect (i.e., density-dependent fertilization success) by using
spatial explicit density estimates. Restoration efforts directed at larger-size individuals may be more effective in increasing population density than efforts focusing on juveniles. I also explored the
spatial nonstationarity in white abalone catch data. I estimated the spatially explicit decline rate and linked the decline rate to environmental factors including water depth, distance to California coast, distance to land, sea surface temperature and chlorophyll concentration. The decline rate showed
spatial variation. I did not detect any significant associations between decline rate and these five environmental factors. Through such a study, I am hoping to provide insights on applying or adapting existing methods to
model spatial dynamics of data-poor species, and on utilizing information from such analyses to aid in their conservation and management.

▼ By developing a simple game in which higher courts and lower courts interact while seeking their own policy goals, this paper examines the reversal behavior of the U.S. Courts of Appeals using the insights of agency theory. Drawing on the
payoffs of the circuit courts and the district courts, the author hypothesizes that appellate courts reverse trial courts strategically. When the preference distance between the two courts is small, higher courts are more likely to reverse lower courts’
decisions that are contrary to lower courts’ own preferences, but to affirm those similar to the lower courts’ own preferences. When the distance is large, the higher courts act opposite. The consistency between policy outcomes of lower courts’ decisions
and their preferences, and higher courts’ reversal propensity are also important factors influencing higher courts’ behavior. An empirical analysis of Courts of Appeals’ economic cases over seven years (1993-1999) partially supports these
expectations.

▼ Part I: Motor Proteins
Fluorescence microscopy is an important technique for studying processive molecular motors such as kinesins and dyneins. A typical experiment generates hundreds or thousands of images of motor assays, and each assay can contain many tens of fluorescent particles that must be localized so that individual motors can be tracked from one image to the next. Previous approaches to processing these images were more algorithmic than statistical, and those approaches typically require human intervention. We address these problems by developing science-informed stochastic models for two types of images: those that use green fluorescent proteins (GFP), and those that use quantum dots. The resulting models permit fully likelihood-based inference for particle count and location. Both procedures are computationally efficient. The procedure for GFP images is fully automatic, while the procedure for quantum dot images requires only a training run on a suitable image.
A kinesin can be furnished with extended neck linkers, i.e., longer ``legs." This modification alters the behavior of the motor, most notably by permitting variable-length steps. We develop renewal-reward type models to describe the stepping of kinesins with extended neck linkers, and present corresponding matrix computational frameworks for conducting computer experiments. This matrix computational approach is much faster than previous Monte Carlo approaches and does not introduce sampling variability. We were able to use the approach to explain important experimental data and to lend support to one of several competing physical models for the neck linker.
Part II: Non-Gaussian Areal Data
Non-Gaussian
spatial data are common in many disciplines. When fitting
spatial regressions for such data, one needs to account for dependence to ensure reliable inference for the regression coefficients. Two models commonly used for
spatial regression on a lattice are the Markov random field
model, or automodel, and the
spatial generalized linear mixed
model (SGLMM), which embeds a Gaussian Markov random field within a hierarchical
model. Although these models have long histories and are very widely used, they pose serious theoretical and computational difficulties: (1) for both classes of models, the regression estimates are uninterpretable due to
spatial confounding; (2) for automodels, the intractable normalizing function makes maximum likelihood and Bayesian inference very challenging; and (3) for the SGLMM, the highly correlated and high-dimensional
spatial random effects make computation very challenging. For a reparameterized version of the autologistic
model, we develop maximum likelihood and Bayesian inferential approaches based on Monte Carlo maximum likelihood (MCML) and an auxiliary-variable MCMC algorithm, both of which employ perfect sampling. This approach addresses computational difficulties while simultaneously resolving interpretability issues. For the SGLMM, we introduce a novel reparameterization based on the underlying graph and…

▼ I present two applications of spatial and spatiotemporal models that stretch the traditional domain of these models, and a method for estimating the marginal likelihood in Bayesian models. Chapter 1 presents a spatial model for causal inference, in the setting of geographic regression discontinuity designs. The model is used to derive estimators of the treatment effect along a geographical border, to develop sensible estimands and estimators of the average treatment effect that account for the topology of the border, and to derive valid hypothesis tests. Chapter 2 addresses a bias in historical records of daily temperature minima and maxima due to the time of day at which the measurements are made, by deploying a spatiotemporal model in a missing data imputation framework. This is enabled by a novel and easy to implement Markov Chain Monte Carlo (MCMC) technique to sample the imputations conditionally on the observed daily extrema. Chapter 3 proposes a method for unbiasedly estimating the log ratio of normalizing constants of two unnormalized distributions, which can be used to estimate the marginal log likelihood of Bayesian models and for Bayesian cross-validation. These quantities are generally challenging to approximate from samples of the posterior, but are important for Bayesian model comparison and selection. I demonstrate the method on a spatial log Gaussian Cox process model and on a high-dimensional Bayesian variable selection model, and discuss how the lack of bias unlocks parallelization on multiple computing units.

▼ Introduction: Gastric cancer (GC) is one of the deadliest diseases as most of the cases are diagnosed at late stages, thereby making treatment almost impossible. GC incidence in North America has been reported to be decreasing over the years. Nevertheless, the primary concern is whether the decrease is valid for all communities?
Purpose and Objectives: The purpose of this study is to identify high-risk GC hotspots in Manitoba and investigate factors associated with GC in Manitoba. The objectives were to (1) describe and investigate the geographical variation of GC incidence in Manitoba; (2) explore factors influencing the geographic change of GC incidence in Manitoba, and (3) investigate the geographical variation of GC incidence over time in Manitoba.
Methods: This research study adopted an ecological design. A
spatial Poisson regression
model was used to address research objectives (1) and (2), and a Spatio-temporal Poisson regression
model was used to address research objective 3.
Results: SESI was significantly associated with cardia gastric cancer (CGC) and marginally associated with non-cardia gastric cancer (NCGC), while the Indigenous population proportion was marginally associated with CGC. In specific, 1 unit increase in SESI reduces the risk of CGC by 14% (IRR= 0.859; 95% CI: 0.780 - 0.947) and the risk of NCGC by approximately 10% (IRR = 0.898; 95% CI: 0.812 – 0.995); 1% increase in regional Indigenous population proportion reduces the risk of CGC by 1.4% (IRR = 0.986; 95% CI: 0.978 – 0.994). Also, 1 unit increase in SESI reduces the risk of CGC among women by 26.2% (IRR = 0.738; 95% CI: 0.618 – 0.879), and a 1% increase in Indigenous population proportion reduces the risk of CGC among women by 1.9% (IRR = 0.981; 95% CI: 0.966 – 0.996).
Conclusion: This study has demonstrated the existence of regional variation of GC incidence risk with temporal pattern in Manitoba.

▼ The gravity
model has been widely used estimate the effect that distance has in international trade; however, two important areas have seen little attention in the literature, namely, the influence of using a more accurate measure of distance and how distance effect estimates change when controlling for
spatial dependence in observed trade flows. Using transportation networks to measure distance and estimating both a
spatial lag and
spatial error gravity
model, Canadian provincial exports to the lower 48 states in the United States were analyzed to address these previously ignored issues. It was found that the traditional distance measure of great circle distance underestimated the distance between any given province and state pair by an average of 20%, however, it did so consistently across all pairs, therefore having no significant influence on the distance effect estimate, regardless of estimation technique. When trade was disaggregated into mode of transportation distance effect estimates differed significantly, reflecting the most efficient uses of each transport mode and also the commodities that flowed across them. Finally, when using the
spatial lag gravity
model, distance effect estimates decreased substantially compared to traditional least squares estimation, while the
spatial error
model provided asymptotically equivalent parameter estimates to least squares, but with overall increased predictive power.

▼ This thesis consists of two parts of essays on analysis of electricity-price policy and we choose South Korea as a case study at the both essays. The objective of the first essay was to analyse the effects of electricity-price policy on electricity demand and manufacturing output, focusing on how these relationships change over space. Our findings suggest that the South Korean government’s plan to increase the electricity price should be implemented with a caution. The plan would achieve the objective of mitigating electricity demand to avoid potential power shortages; however, the more rapid increase in electricity prices may trigger a slowdown in the manufacturing sector. Our findings also imply that South Korean experts’ suggestion of regionally-varying electricity pricing needs further consideration. Although reflecting regional differences in costs of supplying electricity is important, regionally-varying pricing may prompt a slowdown in the Seoul metro area manufacturing sector where manufacturing is more concentrated than in other areas.
The second essay analyzes the relationship between the effects of electricity price on electricity intensity in the manufacturing sector, focusing particularly on how this relationship changes over space and time. We found that increases in electricity price improved electricity-use efficiency in South Korea’s manufacturing sector in the long run, but not in the short run. The regional effects of electricity-price increases on electricity-use efficiency varied depending on time (i.e., short run and long run) and space. The differences may have resulted from different degrees of (1) substitutability of electricity-consuming equipment between the short and long runs and (2) price impact on electricity demand and manufacturing output in the regions’ manufacturing sectors. Our findings imply that first, electricity price increases are likely to be effective as a long-term tool to improve electricity efficiency in the manufacturing sector, but may not be as effective in the short run with some regional exceptions. Second, electricity price increases may hinder electricity-use efficiency in regions characterized by manufacturing sectors where price increases reduce manufacturing output relatively more than they reduce electricity demand.

▼ In this dissertation, we develop a
model selection and estimation methodology for nonstationary
spatial fields. Large, spatially correlated data often cover a vast geographical area. However, local
spatial regions may have different mean and covariance structures. Our methodology accomplishes three goals: (1) cluster locations into small regions with distinct, stationary models, (2) perform Bayesian
model selection within each cluster, and (3) correlate the
model selection and estimation in nearby clusters. We utilize the Conditional Autoregressive (CAR)
model and Ising distribution to provide intra-cluster correlation on the linear effects and
model inclusion indicators, while modeling inter-cluster correlation with separate Gaussian processes. We apply our
model selection methodology to a dataset involving the prediction of Brook trout presence in subwatersheds across Pennsylvania. We find that our methodology outperforms the stationary
spatial model and that different regions in Pennsylvania are governed by separate Gaussian process regression models.
