Structural Controls On The Distribution Of Groundwater In Southern Sinai, Egypt: Constraints From Geophysical And Remote Sensing Observations, Lamees Mohamed
Structural Controls On The Distribution Of Groundwater In Southern Sinai, Egypt: Constraints From Geophysical And Remote Sensing Observations, Lamees Mohamed
Dissertations
An integrated (Very Low Frequency [VLF] electromagnetic, magnetic, remote sensing, field, and Geographic Information System [GIS]) study was conducted over the basement complex in Southern Sinai (Feiran watershed) for a better understanding of the structural controls on the groundwater flow. The increase in satellite-based radar backscattering values following a large precipitation event (date: 17, 18 Jan 2010; amount: 34 mm) was used to identify water-bearing features, here interpreted as preferred pathways for surface water infiltration. Findings include: (1) The distribution of the water bearing features (conductive features) correspond to that of fractures, faults, shear zones, dike swarms, and wadi networks; …
Failing To Replicate: Hypothesis Testing As A Crucial Key To Make Direct Replications More Credible And Predictable, Pedro Fernando Mateu Bullón
Failing To Replicate: Hypothesis Testing As A Crucial Key To Make Direct Replications More Credible And Predictable, Pedro Fernando Mateu Bullón
Dissertations
Theory cannot be fully validated unless the original results have been replicated, resulting in conclusion consistency. Replications are the strongest source to verify research findings and knowledge claims. Sciences such as medicine, chemistry, physics, genetics, and biology, are considered successful because their knowledge claims are buttressed by a large set of replications of original studies. Unfortunately in the social sciences many attempts to replicate fail and thus there is a continuing need for replication studies to confirm facts, expand knowledge to gain new understanding, and verify hypotheses. Two plausible explanations for the failure to replicate in the social sciences could …
Three Essays On Panel Data Estimation, Alexander Houser
Three Essays On Panel Data Estimation, Alexander Houser
Dissertations
This work discusses various aspects of panel data estimation. In chapter one, an algorithm for semiparametric random effects estimation is proposed. The performance of bootstrap-based confidence intervals for the proposed estimators are examined and found reasonable. The algorithm is also applied to a set of U.S. state level medical expenditure data to estimate the medical Engel curve. In the second chapter, the predictive performance of various parametric and semiparametric panel data estimators is compared on the same dataset of U.S. state level medical expenditures as well as out of sample forecast performance and bootstrap bias-corrected mean square errors of the …
Medicare: Program, Procedures And Recommendations, Sarah Wyman
Medicare: Program, Procedures And Recommendations, Sarah Wyman
Honors Theses
My thesis is formatted in the style of a political brief, based upon the program Medicare. This report discusses the question of whether the Medicare program is performing effectively. It discusses the origins and development of Medicare, its mission and reason for the program. Included is the staffing of the Centers for Medicare and Medicaid Services, a center within the Department of Health and Human Services. It discusses the historical, current, and projected funding through FY 2015. Most notably it contains the program performance ratings of Medicare from the White House, CBO, OMB, and CMS. Medicare is a program that …

Governance Of Land And Natural Resource For Sustainable Development In Botswana: Possible Lessons For The Agricultural And Tourism Sectors, David Sebudubudu, Patricia M. Makepe, Kgomotso Montsi, Keratilwe Bodilenyane
International Journal of African Development
Realizing sustainable development is a major challenge for most African countries. Economic growth in most African countries is largely centered on the extraction of natural resources, particularly minerals. Rather than facilitate development, the extraction of natural resources in most countries, has been a source of adverse outcomes. That is, natural resources led to ‘the resource curse’, partly because of bad governance and leadership. Through governance and leadership, Botswana emerged differently. The country transformed itself to a middle income status through the prudent utilization and management of mineral (non-renewable) resources; making Botswana one of the few resource rich countries that have …
