Bat activity over wetlands: temporal and spatial variation
… which can fluctuate temporally as well as spatially. For temperate insectivorous bats, wetlands are important forage habitats because they provide water and high abundances of insects. My overall objective was to identify abiotic and biotic factors that influence bat foraging activity over …

Spatial Variation of Cardiac Restitution and the Onset of Alternans
… does not flow. It is generally believed that the spatial scale for boundary effects is approximately equal to the passive length constant, lambda, of the tissue, the distance over which a a voltage pulse decays when it is below the threshold for wave generation. From the results of <em>in …

Spatial variation of AMD related CO₂ emissions on reclaimed mine spoil
… (ii) CO₂ fluxes are not always random but spatially autocorrelated; (iii) AMD-derived CO₂ emissions are normally too low to successfully be used to delineate hazards. This pioneering effort also makes recommendations for future work that could make AC flux measurement more effective for …

Power in Transition: The Spatial Variation of Territorial Cohesion in Kazakhstan
… aspects of effective national territory and spatial inequalities, focusing on better integration of regions through balanced economic growth, reducing regional disparities, and inclusive policies toward all citizens. Lack of cohesion and instability result from poorly managed government …

Acoustics of the Salt Lake Tabernacle: Characterization and Study of Spatial Variation
… of the seating areas of the hall to show the spatial variation of the acoustics. To further investigate the variation, statistics were calculated for each parameter and an algorithm was developed to determine the minimum number of receiver locations necessary to adequately characterize the …

Spatial variation of Allanblackia parviflora seed products in Ghana: Chemical and ethnobotanical exploration
… in Ghana. It is for this reason that this study “Spatial variation of Allanblackia parviflora seed products in Ghana: chemical and ethnobotanical exploration” is very unique and original in nature. The present study does not only look at the oil production from the seeds and kernels but also at …

Temporal and Spatial Variation of Fine Sediment Infiltration in a Gravel-Bed River
… My work suggests that because the timing and spatial variability of substrate reworking strongly influence fine sediment content in river beds, understanding of such factors is essential to remediation efforts concerned with fine sediment infiltration.

Modulation of Murine Intestinal Gene Expression by Dietary Fat: Spatial Variation and Saturation Effect
Thesis summary: Traditional approaches investigate the linear effect of high-fat over-consumption on transcriptomic data. However, many biological processes occur in a nonlinear fashion. The objective of this PhD thesis is to study the response types of dietary fat mediated differentially expressed …

Economic Inequality Through a Contextual Lens: Spatial Variation in Beliefs, Opinion, and Policy Support
… wage rates. In the third chapter, I highlight variation in the contextual economic characteristics that U.S. residents may encounter and explore the implications of strategies for measuring local income inequality and segregation. I then examine the associations between individuals’ perceptions …

Industrial organization of housing supply : explaining spatial variation of home builder size in U.S.
… use, and capital. Research has revealed a strong variation between the supply sector and builders' behavior patterns. Understanding these variations will contribute not only to better performance of private homebuilders, but also to more efficient housing supply policy. Somerville's impressive …

Spatial variation in small mammal communities across the Karoo Shale Gas Development Area of South Africa
… a relatively robust data set for subsequent spatial diversity analyses. However, even the total species richness dataset is likely to underestimate true diversity owing to not sampling arboreal species or detecting some cryptic species. Generalized linear analyses indicated that small mammal …

Spatial Variation of Magnitude Scaling Factors During the 2010 Darfield and 2011 Christchurch, New Zealand, Earthquakes
… the context of the simplified procedure, the spatial variation in the seismic demand imposed on the soil traditionally has been assumed to be solely a function of the spatial variation of the peak amplitude of the ground motions and the characteristics of the soil profile. Conversely, MSF have …

Cycling in the Crescent City: An exploration of the spatial variation in bicycle commuting in New Orleans
<p>This thesis examines the spatial variation in bicycle commuting across New Orleans. It identifies where in the city bicycle commuting is most and least prevalent. It also explores factors that are promoting and discouraging utilitarian bicycling. A review of existing literature on variables …

Spatial variation of the food price index in Canada's Northwest Territories: a ridge regression analysis
This thesis investigates the spatial variation in the 1985 Food Price Index (FPI) at destinations in the Northwest Territories (NWT). It follows a conceptual model that assumes the FPI varies directly with the accessibility of a given northern destination to the metropolitan South. Accessibility …

Spatial variation in functional traits and grazing value of savanna grasses at the community and species level
… strongly between species, with intra-specific variation in grazing quality often ignored, resulting in grass species often uniformly being categorized as being of high or low grazing quality. There is, however, an increasing debate about the validity of this approach since many grass …

Placing Psychology: A Psychometric and Econometric Approach to Understanding Spatial Variation in Personality and its Consequential Outcomes
… the composition, causes and consequences of spatial variation in personality. The research presented in this thesis aims to better understand our behaviour by adopting a lens that incorporates information on who we are and where we are. After giving a general introduction in Chapter 1, I will …
