—The detection of materials or devices for nuclear or radiological weapons of mass destruction is fundamentally important to national safety and security, and detection technologies are necessary both to nd and to verify the location of those materials or devices. To ful ll this task, this paper presents a statistical approach to the detection and location of radioactive target via wireless sen...

One of the principal concerns in graduate admissions is how future performance in graduate studies may be predicted from a candidate’s undergraduate achievements. In this study, we examined the statistical relationship between B.Sc. and M.Sc. achievements using a dataset that is not subject to an admission-induced selection bias. Our analysis yielded three insights. First, we were able to expla...

In the first part we show a counterexample to a conjecture by Shelah regarding the existence of indiscernible sequences in dependent theories (up to the first inaccessible cardinal). In the second part we discuss generic pairs, and give an example where the pair is not dependent. Then we define the notion of directionality which deals with counting the number of coheirs of a type and we give ex...

In December 2008, the US Commission on the Prevention of Weapons of Mass Destruction Proliferation and Terrorism, released a report, World At Risk. The Report points to the fact that, not only is the use of a weapon of mass destruction in a terrorist attack before the end of 2013, more likely than not, but also to the fact that terrorists are more likely to be able to obtain and use biological ...

This paper examines the interplay of social and temporal distance on consumers’ responses to others’ recommendations. Drawing on research on psychological distance and the “fit” literature, the authors hypothesize that others’ recommendation is more persuasive when the construal levels associated with both social distance and temporal distance are congruent. Specifically, the authors first demo...

INTRODUCTION With limited available hospital beds in most urban areas, there are very few options when trying to relocate patients already within the hospital to make room for incoming patients from a mass-casualty incident (MCI) or epidemic (a patient surge). This study investigates the possibility and process for utilizing shuttered (closed or former) hospitals to accept medically stable, amb...

where Ed= fl, bkEZ2,, k 2 1, and with some constraints on bk and sk. Usually we will assume that x is irrational, and thus that the expansion (1.1) is infinite. A special case of an SRCF is the regular continuedfraction, RCF, which is obtained by taking ck = 1 for every k in (1.1). The aim in introducing the OCF was to optimize two things simultaneously. In the first place one wishes the conver...

Increased understanding of the stress and performance effects of gun range drills with police officers is of importance for law enforcement trainers. Seventy-one police officers participated in routine night shooting drills over a two week period as part of regular training regimen. This paper examines the effects of two shooting range tasks on police officer’s time perception, individual diffe...
