Based on the revised social contact theory, correlates of cross-ethnic friend nomination among 580 African American, 948 Asian-descent, 860 Latino, and 3986 White adolescents were examined. Socioeconomic and academic disparities between ethnic groups differentiated cross-ethnic friend nomination between schools for all groups but African Americans. For all groups, cross-ethnic friend nomination...

Argumentation, whether philosophical or formal and mathematical, is a discipline of interdisciplinary nature, per se. The recent works on the computational argumentation formalism and their foundations, however, have rested only on logic or logical account. In this paper, we reconsider Dung’s seminal argument acceptability notion in the context of Heider’s socio-psychological balance theory, wh...

BACKGROUND Exaggerated cardiovascular reactions to psychological stress are considered a risk factor for cardiovascular morbidity. Social support may reduce such risk by attenuating cardiovascular reactivity to stress. PURPOSE To examine the effects of three independent social support variables and their interaction on cardiovascular reactivity to acute stress. The variables were stranger or ...

Society’s increasing reliance on digital communication networks is creating unprecedented opportunities for wholesale surveillance and censorship. This thesis investigates the use of public networks such as the Internet to build robust, private communication systems that can resist monitoring and attacks by powerful adversaries such as national governments. We sketch the design of a censorship-...

Electronic Support Measures consist of passive receivers which can identify emitters coming from a small bearing angle, which, in turn, can be related to platforms that belong to 3 classes: either Friend, Neutral, or Hostile. Decision makers prefer results presented in STANAG 1241 allegiance form, which adds 2 new classes: Assumed Friend, and Suspect. Dezert-Smarandache theory (DSmT) is particu...

An example of game theory is the classic Prisoner’s Dilemma. Suppose you and a friend are arrested for robbery. You are put in separate cells. The police lack sufficient evidence to convict either of you, so they try to get one of you to testify against each other. The police tell you that if you testify against your friend, you will be released, provided your friend does not testify against yo...

A theory T is trustworthy iff, whenever a theory U is interpretable in T , then it is faithfully interpretable. In this paper we provide a characterization of trustworthiness. We provide a simple proof of Friedman’s Theorem that finitely axiomatized, sequential, consistent theories are trustworthy. We provide an example of a theory whose schematic predicate logic is complete Π2.

The Bayesian approach to quantummechanics of Caves, Fuchs and Schack is presented. Its conjunction of realism about physics along with antirealism about much of the structure of quantum theory is elaborated; and the position defended from common objections: that it is solipsist; that it is too instrumentalist; that it cannot deal with Wigner’s friend scenarios. Three more substantive problems a...
