This paper proposes Chebyshev-dependent inhomogeneous second order differential equation for the m-Boubaker polynomials (or Boubaker-Turki polynomials). This differential equation is also presented as a guide to applied physics studies. A concrete example is given through an attempt to solve the Bloch NMR flow equation inside blood vessels.

The Evolution Of Reciprocity In Sizable Human Groups, Casey G. Rothschild

Economics Faculty Scholarship

The scale and complexity of human cooperation is an important and unresolved evo- lutionary puzzle. This article uses the finitely repeated n person Prisoners’ Dilemma game to illustrate how sapience can greatly enhance group-selection effects and lead to the evolutionary stability of cooperation in large groups. This affords a simple and direct explanation of the human “exception.”

Evaluation Of The Stability And Validity Of Participant Samples Recruited Over The Internet., Daniel Z Lieberman

Psychiatry and Behavioral Sciences Faculty Publications

Research conducted via the Internet has the potential to reach important clinical populations of participants who would not participate in traditional studies. Concerns exist, however, about the validity of samples recruited in this manner, especially when participants are anonymous and never have contact with study staff. This study evaluated two anonymous samples that were recruited over the Internet to test an online program designed to help problem drinkers. The two studies were conducted 3 years apart, and different recruitment strategies were utilized. Despite these differences, the two samples were highly similar in demographic and clinical features. Correlations that have been …

Ttl Based Packet Marking For Ip Traceback, Vamsi Paruchuri, Arjan Durresi, Sriram Chellappan

Computer Science Faculty Research & Creative Works

Distributed Denial of Service Attacks continue to pose major threats to the Internet. in order to traceback attack sources (i.e., IP addresses), a well-studied approach is Probabilistic Packet Marking (PPM), where each intermediate router of a packet marks it with a certain probability, enabling a victim host to traceback the attack source. in a recent study, we showed how attackers can take advantage of probabilistic nature of packet markings in existing PPM schemes to create spoofed marks, hence compromising traceback. in this paper, we propose a new PPM scheme called TTL-Based PPM (TPM) scheme, where each packet is marked with …

Moving Towards Illumination? The Development Of Method And Rhetoric In The American School Of Archaeologists, Jeremy R. Brown

Seminary Masters Theses

This thesis examines two aspects of the work the American School of archaeologists: 1) their refinements of archaeological method; and 2) their cultivation of a particular rhetorical strategy to describe the significance of their findings In the first chapter, we explore the rise of Near Eastern archaeology from the mid-nineteenth century through the early-twentieth century. During this time many communities of faith joined in the digging in hopes of locating finds with biblical implications. A lofty rhetoric was developed to describe these discoveries and to relate their impact upon the accounts of the Bible. This period was marked by the …

“It’S A Choice, Simple As That”: Youth Reasoning For Sexual Abstinence Or Activity, Rochelle L. Dalla

Department of Child, Youth, and Family Studies: Faculty Publications

This investigation was designed to fill gaps in the extant literature by examining reasons give by youth for refraining from or engaging in sexual intercourse, in addition to their perceptions regarding the advantages and disadvantages of premarital intercourse. Quantitative and qualitative data were collected from 103 graduating seniors; 60 self-identified as sexually abstinent and 43 as sexually active. Survey indices were used to assess parent-youth relationships, and parent and peer attitudes toward premarital sex, religiosity, and dating patterns; open-ended questions were used to assess reasons for either engaging in or refraining from sexual intercourse, and to identify benefits and problems …

Changes In The Distribution Of Income Among Single Mother Families: Murphy Brown Meets Inequality, Christopher Bollinger, James P. Ziliak

University of Kentucky Center for Poverty Research Discussion Paper Series

We document the demographic and economic forces underlying changes in income inequality among single mother families over the past three decades in the United States. Using decomposable measures of after-tax income-to-needs inequality, we examine within- and between-group inequality based on education attainment, age, past marital status, race, and employment status. We also conduct income factor decompositions to quantify the relative contributions of earnings, transfers, other income, and taxes to inequality. Our results from the March Current Population Survey show that income-to-needs inequality rose nearly 30 percent between 1979 and 2005. The demographic decompositions indicate that most of the change in …

Daily Variation And Predicting Stock Market Returns For The Frankfurter Börse (Stock Market), Jeffrey E. Jarrett, Janne Schilling

College of Business Faculty Publications

In this article we test the random walk hypothesis in the German daily stock prices by means of a unit root test and the development of an ARIMA model for prediction. The results show that the time series of daily stock returns for a stratified random sample of German firms listed on the stock exchange of Frankfurt exhibit unit roots. Also, we find that one may predict changes in the returns to these listed stocks. These time series exhibit properties which are forecast able and provide the intelligent data analysts' methods to better predict the directive of individual stock returns …

A Comparison Of Two Probability Encoding Methods: Fixed Probablity Vs. Fixed Variable Values, Ali E. Abbas, David V. Budescu, Hsiu-Ting Yu, Ryan Haggerty

Psychology Faculty Publications

We present the results of an experiment comparing two popular methods for encoding probability distributions of continuous variables in decision analysis: eliciting values of a variable, X, through comparisons with a fixed probability wheel and eliciting the percentiles of the cumulative distribution, F(X), through comparisons with fixed values of the variable. We show slight but consistent superiority for the fixed variable method along several dimensions such as monotonicity, accuracy, and precision of the estimated fractiles. The fixed variable elicitation method was also slightly faster and preferred by most participants. We discuss the reasons for its superiority and conclude with several …

Developing 1990, 2000, And 2005 Impervious Surface Estimates For Southern York County, Maine, David G. Justice, Fay A. Rubin

PREP Reports & Publications

Estimates of impervious surface acreage in 1990, 2000, and 2005 were generated for an 11-town region in York County, Maine, covered by the Piscataqua Region Estuaries Partnership (PREP). The project extended previous work done in New Hampshire, relying on comparable satellite-based data sources and image processing methodologies. As a result, standardized impervious surface estimates are now available for the entirety of the PREP region. The impervious surface estimates were derived by applying both traditional and subpixel classification techniques to 30-meter Landsat 5 Thematic Mapper (TM) and Landsat 7 Enhanced Thematic Mapper Plus (ETM+) satellite image data. The classifications indicated that …
