"This great painting was later renamed, with fitting opportunism, The Premonition of Civil War." (Caption); "The events of October 1934, and his scare in Barcelona, seem to have convinced Dali that civil war was a real possibility in...
Freshwater zooplankton; Global warming; Nitrogen--Environmental aspects
Aquatic ecosystems face major transformations as humans increasingly alter their environment by introducing exotic species and changing the temperature regime and nutrient availability of freshwater systems. The impacts of such alterations of...
Data from the Health and Retirement Study (HRS) were used to examine factors that influence emotional distress in older adults with cancer, arid to learn whether these distress trajectories are different from older adults without cancer. The model...
For complex classification systems, data is usually gathered from multiple sources of information that have varying degree of reliability. In fact, assuming that the different sources have the same relevance in describing all the data might lead to...
From a computerized image analysis prospective, early diagnosis of lung cancer involves detection of doubtful nodules and classification into different pathologies. The detection stage involves a detection approach, usually by template matching,...
In this study, the author examined the relationship of probability misconceptions
to algebra, geometry, and rational number misconceptions and investigated the potential
of probability instruction as an intervention to address misconceptions in all...
Data mining; Lungs--Cancer; Outcome assessment (Medical care)
Lung cancer is the leading cause of cancer death in the United States and the world, with more than 1.3 million deaths worldwide per year. However, because of a lack of effective tools to diagnose Lung Cancer, more than half of all cases are...
Marginal inference for waiting times in multi-stage time-to-event models is complicated by right censoring of observations as well as the prior history of events in the model. In general, complications arise due to the evolution of the censoring...
Surface active agents; Rendering industry--Waste disposal; Air filters
Meat is a major component of the diet of an American. However, humans do not consume one-third to one-half of each animal raised for their needs. The leftover materials are subjected to processing in the meat rendering industry. The rendering...
New firms face financial constraints that could hinder firm performance. Yet founders exhibit persistence and resourcefulness in building their new ventures and finding solutions to their financial constraints. The use of financial theories that...
Electronic commerce--Corrupt practices--Prevention; Internet advertising--Corrupt practices; Internet fraud
Online search advertising is currently the greatest source of revenue for many Internet giants such as Google™, Yahoo!™, and Bing™. The increased number of specialized websites and modern profiling techniques have all contributed to an...
Influenza--United States--Management; Epidemics--Management; Health services administration; Mathematical optimization
Pandemic influenza has been an important public health concern. During the 20th century, three major pandemics of influenza occurred in 1918, 1957, and 1968. The pandemic of 1918 caused 40 to 50 million deaths worldwide and more than 500,000 deaths...
Radio frequency allocation; Wireless communication systems
Recently, the need for wireless and mobile communications has grown tremendously and it is expected that the number of users to be supported will increase with high rates in the next few years. Not only the number of users, but also the required...
Regression analysis is a statistical method used to relate a variable of interest, typically y (the dependent variable), to a set of independent variables, usually, X1, X2,...,Xn . The goal is to build a model that assists statisticians in...
Colon (Anatomy)--Cancer--Genetic aspects; Cancer cells--Mathematical models
Research over the past twenty five years has led to the development of the hypothesis that colorectal cancer is caused by the accumulation of mutations in tumor suppressor genes and proto-oncogenes. The last ten years has also revealed that the...
Teachers of children with disabilities--Attitudes; Teacher-student relationships; Developmentally disabled children--Education; Affective education
The First Step to Success early intervention program (Walker, 1998) is a
secondary prevention intervention that targets primary grade children with moderate or
emerging behavior disorders. While the effectiveness of the First Step to Success...
The following thesis examines the relationship between site geology and ground motion amplification for medium sized earthquake events in the Ohio Valley area. This thesis also includes a Rapid Screening Guide that can be used to estimate...
Medical records--Data processing; Data mining; Medical care--Data processing; Coronary heart disease--Treatment
The goal of this study is to use a data mining framework to assess the three main treatments for acute myocardial infarction: thrombolytic therapy, percutaneous coronary intervention (percutaneous angioplasty), and coronary artery bypass surgery....
Images, Photographic--Databases; Image processing--Digital techniques; Data mining; Cluster analysis
The performance of content-based image retrieval systems has proved to be inherently constrained by the used low level features, and cannot give satisfactory results when the user's high level concepts cannot be expressed by low level features. In...
The phase II clinical trial is a critical step in the drug development process. In the oncology setting, phase II studies typically evaluate one primary endpoint, which is efficacy. In practice, a binary measurement representing the response to the...
