An Assessment Of Malaria Risk In Koton Karfe Watershed Catchment, Nigeria, Olarewaju Oluseyi Ifatimehin Mar 2009

An Assessment Of Malaria Risk In Koton Karfe Watershed Catchment, Nigeria, Olarewaju Oluseyi Ifatimehin

Olarewaju Oluseyi Ifatimehin

This study adopts ground survey and questionnaire administration to determine environmental and socio-economic factors contributing to malaria risk in Koton Karfe watershed catchment. A health facilty-based survey is carried out to assess tbe ratio of population to health facility. The study reveals that poverty is the overriding risk factor determining the high malaria incidence rate which ranges from 40/1000 per annum to 288/1000 per annum across watershed catchment and prevelant among infants and school age children. The nearest neighbour index of 1.48 suggests the randomness in the spatial distribution of health facilities. The increase in the burden of malaria on …

A Plotless Density Estimator Based On The Asymptotic Limit Of Ordered Distance Estimation Values, Barry J. Kronenfeld Jan 2009

A Plotless Density Estimator Based On The Asymptotic Limit Of Ordered Distance Estimation Values, Barry J. Kronenfeld

Barry J. Kronenfeld

Estimation of tree density from point-tree distances is an attractive option for quick inventory of new sites, but estimators that are unbiased in clustered and dispersed situations have not been found. Noting that bias of an estimator derived from distances to the kth nearest neighbor from a random point tends to decrease with increasing k, a method is proposed for estimating the limit of an asymptotic function through a set of ordered distance estimators. A standard asymptotic model is derived from the limiting case of a clustered distribution. The proposed estimator is evaluated against 13 types of simulated generating processes, …


An Evaluation Of The Effect Of Land Use/Cover Change On The Surface Temperature Of Lokoja Town, Nigeria, Fanan Ujoh Mr, Olarewaju O. Ifatimehin Mr, John Y. Magaji Dr Jan 2009

An Evaluation Of The Effect Of Land Use/Cover Change On The Surface Temperature Of Lokoja Town, Nigeria, Fanan Ujoh Mr, Olarewaju O. Ifatimehin Mr, John Y. Magaji Dr

Dr. Fanan Ujoh

This research integrated remote sensing and Geographic Information Systems (GIS) to identified land use/cover types in Lokoja, including their temporal transformation and association with surface temperatures from the LandSat TM and LandSat ETM imageries of 1987 and 2001 respectively. As the built-up area increased in size (2667.6%) so was the surface temperature (6.48oC), vacant land (872%: 9.65oC), cultivated land (104.4%: 1.2oC) and water bodies (64.3%:0.94oC) while vegetation cover increased by 2.44oC while its area extent decreased (316.7%). These changes were responsible for the rise in the mean surface temperature from 38.39oC in 1987 to 42.61oC in 2001, indicating a 4.22oC …

Using Indigenous Knowledge In Land Use Planning And Management: A Participatory Gis Approach, Olarewaju Oluseyi Ifatimehin

Olarewaju Oluseyi Ifatimehin

An increasing global concern that has been consistently facing the human population today is the declining natural resources especially land resources. Land resources are threatened by the increasing pressures exerted by the expanding human needs and economic activities, and thus impose adverse effect on the environment, biodiversity, and the global climate systems. Information describing the land resources of a region does forms the bases upon which sustainable development can be built. The local people perception of being local with a complex, diverse and uncontrolled problems and tied down to a livelihood that depends mainly on primary production system (utilization of …


The Use Of Computer Intelligent Processing Technologies Among Environmental Scientists In Nigerian Universities, Olarewaju Oluseyi Ifatimehin Jan 2009

The Use Of Computer Intelligent Processing Technologies Among Environmental Scientists In Nigerian Universities, Olarewaju Oluseyi Ifatimehin

Olarewaju Oluseyi Ifatimehin

This paper assesses the awareness and usage of a novel approach to data and information processing among scientists, researchers and students in the field of environmental sciences. In depth and structured interview was conducted, targeting a population who are working in a variety of environmental issues. The data generated were analysed using simple descriptive statistics. The results indicate that the level of awareness and responsiveness to this approach is very low (26.5%), and computer proficiency is also very low (30.8%). This suggests the need for a vigorous academic reorientation of all stakeholders through conferences, workshops and seminars.

Modeled Red Spruce Distribution Response To Climatic Change In Monongahela National Forest, James Michael Stanton Jan 2009

Modeled Red Spruce Distribution Response To Climatic Change In Monongahela National Forest, James Michael Stanton

Theses, Dissertations and Capstones

In Monongahela National Forest of West Virginia, red spruce grows in high-elevation island ecosystems that are particularly sensitive to changes in climatic conditions. The ecological niche modeling application Maxent was used to project the distribution response of red spruce to climatic change for the purposes of conservation planning. Red spruce distribution data was acquired from the United States Forest Service. Three sets of nineteen bioclimatic variables, corresponding to present, 2050, and 2080 conditions, were derived from 1961-1990 monthly temperature and precipitation means and the IPCC A2 emissions scenario of HadCM3. The modeling revealed rapidly diminishing red spruce habitat suitability from …


Surface Mining And Reclamation Effects On Flood Response Of Watersheds In The Central Appalachian Plateau Region, Todd R. Lookingbill, Joseph R. Ferrari, B. Mccormick, P. A. Townsend, K. N. Eshleman Jan 2009

Surface Mining And Reclamation Effects On Flood Response Of Watersheds In The Central Appalachian Plateau Region, Todd R. Lookingbill, Joseph R. Ferrari, B. Mccormick, P. A. Townsend, K. N. Eshleman

Geography and the Environment Faculty Publications

Surface mining of coal and subsequent reclamation represent the dominant land use change in the central Appalachian Plateau (CAP) region of the United States. Hydrologic impacts of surface mining have been studied at the plot scale, but effects at broader scales have not been explored adequately. Broad-scale classification of reclaimed sites is difficult because standing vegetation makes them nearly indistinguishable from alternate land uses. We used a land cover data set that accurately maps surface mines for a 187-km2 watershed within the CAP. These land cover data, as well as plot-level data from within the watershed, are used with HSPF …


A Cluster Identification Framework Illustrated By A Filtering Model For Earthquake Occurrences, Zhengxiao Wu Jan 2009

A Cluster Identification Framework Illustrated By A Filtering Model For Earthquake Occurrences, Zhengxiao Wu

Research Collection School of Economics

A general dynamical cluster identification framework including both modeling and computation is developed.The earthquake declustering problem is studied to demonstrate how this framework applies.A stochastic model is proposed for earthquake occurrences that considers the sequence of occurrencesas composed of two parts: earthquake clusters and single earthquakes. We suggest that earthquake clusterscontain a “mother quake” and her “offspring.” Applying the filtering techniques, we use the solution offiltering equations as criteria for declustering. A procedure for calculating maximum likelihood estimations(MLE’s) and the most likely cluster sequence is also presented.


The ‘Benchmark Glacier’ Concept – Does It Work? Lessons From The North Cascade Range, Usa, Andrew G. Fountain, Matthew J. Hoffman, Frank Granshaw, Jon L. Riedel Jan 2009

The ‘Benchmark Glacier’ Concept – Does It Work? Lessons From The North Cascade Range, Usa, Andrew G. Fountain, Matthew J. Hoffman, Frank Granshaw, Jon L. Riedel

Geology Faculty Publications and Presentations

Benchmark glaciers were established in many alpine areas during the 1960s as part of the International Hydrological Decade to represent ‘typical’ mass and energy processes on glaciers in different climatic regions around the world. These glaciers have received new interest in the past decade because they are used to infer the contribution of alpine glacier wastage to global sea-level rise. We compare South Cascade Glacier, the benchmark glacier for the northwest contiguous USA, and four other secondary glaciers, against the topographic, area and mass changes of 321 glaciers in the surrounding region. Results show that South Cascade Glacier is unusually …

The Legacy Of Race Based Slavery In The United States, Jennifer Maloney Jan 2009

The Legacy Of Race Based Slavery In The United States, Jennifer Maloney

Pell Scholars and Senior Theses

Alexis de Tocqueville qualifies the race based slavery of the United States as the greatest evil in the history of man. Through the lens of Tocqueville, I will examine the origin, nature, and characteristics of the race based system of slavery that was born in colonial times up to the implementation of the Civil Rights movement of 1964. The focus of this presentation will be on the dramatic effect that climate and topography have on the development of regional character, and the accuracy of Tocqueville's predictions concerning the future of race relations in the United States.

The Palaeoceanography Of The Leeuwin Current : Implications For A Future World, Karl-Heinz Wyrwoll, Benjamin J. Greenstein, George Kendrick Jan 2009

The Palaeoceanography Of The Leeuwin Current : Implications For A Future World, Karl-Heinz Wyrwoll, Benjamin J. Greenstein, George Kendrick

Arts & Sciences Faculty Publications

Long-term progressive changes of the Leeuwin Current are linked to plate and ocean basin ‘geography’ and Cenozoic global climates and palaeoceanography. Suggestions of the presence of a proto-Leeuwin Current as early as late Middle to Late Eocene times (c. 35–42 Ma) cannot be verified by the fossil record of the western margin of Australia. “Leeuwin Current style” circulation around Australia was certainly established by the early Oligocene, in response to palaeogeographic changes in the Tasman Strait. This, followed by tectonic eorganisation of the Indonesian Archipelago throughout the Miocene, provided a palaeogeographic setting, which by the Pliocene was essentially that of …


The Role Of Landscape Connectivity In Assembling Exotic Plant Communities: A Network Analysis, Emily S. Minor, Samantha M. Tessel, Katharina A.M. Engelhardt, Todd R. Lookingbill Jan 2009

The Role Of Landscape Connectivity In Assembling Exotic Plant Communities: A Network Analysis, Emily S. Minor, Samantha M. Tessel, Katharina A.M. Engelhardt, Todd R. Lookingbill

Geography and the Environment Faculty Publications

Landscape fragmentation and exotic species invasions are two modern-day forces that have strong and largely irreversible effects on native diversity worldwide. The spatial arrangement of habitat fragments is critical in affecting movement of individuals through a landscape, but little is known about how invasive species respond to landscape configuration relative to native species. This information is crucial for managing the global threat of invasive species spread. Using network analysis and partial Mantel tests to control for covarying environmental conditions, we show that forest plant communities in a fragmented landscape have spatial structure that is best captured by a network representation …


Quantifying The Overwash Component Of Barrier Island Morphodynamics: Onslow Beach, Nc, Amy C. Foxgrover Jan 2009

Quantifying The Overwash Component Of Barrier Island Morphodynamics: Onslow Beach, Nc, Amy C. Foxgrover

Dissertations, Theses, and Masters Projects

A quantification of the role that barrier island overwash plays in the evolution of Onslow Beach, a barrier island located on Marine Corps Base Camp Lejeune, North Carolina, is presented. Ground-penetrating radar (GPR) and sediment vibracores provide an estimate of the relevant-sand prism above a silty/peat contact underlying the island. The average thickness from the surface, as determined from lidar, to this geologically-defined base, is less than 1 m and equates a total volume of approximately 1.8 ± 1.1 × 106 m3 over the 4.8 km stretch of Onslow Beach from 1 km north of the New River Inlet to …

Flame, Furnace, Fuel: Creating Kansas City In The Nineteenth Century, Twyla Dell Jan 2009

Flame, Furnace, Fuel: Creating Kansas City In The Nineteenth Century, Twyla Dell

Antioch University Full-Text Dissertations & Theses

Though this work is a fuel and energy history of Kansas City from 1820 to 1920, it also provides a tool to describe and analyze fuel and energy transitions. The four parts follow the rise and fall of wood, coal and oil as their use grows to a peak and, in the case of wood, declines. The founding and growth of Kansas City as an “instant city” that grew from zero population to over three hundred twenty thousand in a hundred years embodies the increased use of fuels and energy in an urban setting and serves as a case study. …
