A Spatial Analysis of Obesity and Its Associations with the Built and Natural Environment, Physical Inactivity, and Socioeconomic and Demographic Conditions in the United States of America
… in the US, a clearer understanding of how spatial associations between obesity and confounding factors are interrelated is crucial to better tackle the issue of obesity. This study employs the ‘global’ and ‘local’ Exploratory Spatial Data Analysis (ESDA) methods including the Ordinary Least …

Domestic Landscapes, Power, and Political Change: Comparing Classic Maya Communities in the Three Rivers Region of Northwestern Belize (A.D. 600 - 1000)
… two parts: 1) the community patterns of house spatial associations to each other, environmental features, public centers, and infrastructure; 2) the household patterns of ceramic choices and house designs. What I found was that La Milpa and Ixno'ha shared many domestic landscape traits with …

An investigation of terrestrial arthropod herbivory in Pennsylvanian peat forests revealed by coprolites from coal balls
… through morphometrics, content analysis, and spatial associations. Chapter 5 reconstructs Pennsylvanian arthropod–plant interaction networks using bipartite analysis, revealing a shift from the low-diversity, detritivore-dominated Springfield Coal network to the more diverse, trophically …

The earth's interior from both a seismological and petrological perspective
… medium. A separate focus of this thesis is how spatial associations between minerals in a thin-section can be used to infer the evolutionary pressure-temperature history of a rock. I present a new method for textural analysis that uses digital images obtained with the electron microprobe. This …

Sensitivity of northern red oak (Quercus rubra L.) to variation of temperature and moisture availability along latitudinal and longitudinal climate gradients
Spatial distribution of species and thus the composition of deciduous forests are expected to change in response to global climatic warming. Climate-growth response algorithms in forest simulation models that represent the influence of climate on tree growth are based on the geographic range limits …

Nonrandom seed dispersal by lemur frugivores: mechanism, patterns and impacts
… dispersal foci, lemur frugivores structure the spatial associations between dispersed seeds and adult-trees nonrandomly, in terms of fruiting time, dispersal mode and phylogenetic relatedness. However, lemur-dispersed tree species were not more likely to be each other’s neighbors as adults. …

Population ecology of Pseudacteon tricuspis Borgmeier (Diptera: Phoridae), an introduced parasitoid of the red imported fire ant Solenopsis invicta Buren (Hymenoptera: formicidae) in Louisiana
… 1 functional response. Modelling of the local spatial population structure of P. tricuspis, and relationship of abundances to host social form and pathogen-infected colonies, revealed no significant spatial associations between fly counts and infected host colonies. When fly populations peaked, …

Jesus and land: constructions of sacred and social space in Second Temple Judaism
… and Josephus’ Antiquities show very different spatialisations and views of cosmic order. They also come out of very different settings in life and show something of the ways that land (in relationship to other nations) could be understood in the Second Temple Period. Chapter Three explores the …

Know your place - Social network analysis in cooperatively breeding white-winged choughs (Corcorax melanorhamphos)
… the Canberra area and constructed networks from spatial association data to give values for two group-level and three individual-level social network measures. The two group-level social network measures were the extent of their assortative behaviour based on their traits (assortativity) and …

Climate-Triggered Drought as Causes for Different Degradation Types of Natural Forests
… and greenness loss, and their variations were spatially assessed with monthly and inter-seasonal precipitation anomalies from 2000 to 2016. Specifically, dimensions of forest droughts were evaluated in relations with the dimensions of meteorological and hydrological droughts. Large-scale …

A Multi-Method Analysis of the Role of Spatial Factors in Policy Analysis and Health Disparities Research
… spaces. The multi-disciplinary approach links spatial conceptual perspectives from rural sociology and health geography to provide the theoretical framework for the relevance of integrating space in policy analysis and diet and health disparities research. The multi-method approach provides a …

Millimetre and Submillimetre continuum imaging studies of nearby active galaxies
… of the cool to cold dust (~ 80 to 10K) and its associations with star formation and nuclear activity in the galaxies. The observations of Cygnus A constrained the galaxy's cold dust temperature between 37 and 85K, corresponding to dust masses between 1.0 x 10 8M® and 1.4 x 106M® respectively. …

Assessing the potential contribution of roads to variation in British bird populations
… data from across Great Britain to assess the spatial associations between the density and traffic volumes of roads, and bird populations in the surrounding areas. In Chapter 1, I provide background detail on the impacts of roads on birds and introduce the premise and necessity of my thesis. In …

Spatial urban environmental change and Malaria/Diarrhoea mortality in Accra, Ghana
… change might differ by season and across spatial boundaries. While there is a complete understanding that the magnitude and scale of environmental change process are driven by a combination of both demographic and socioeconomic forces, the fractional contribution of the different forces to …
