The conventional view of the impact of terrorism on democracy in America since 9/11 is bleak. Pundits in the mass media, candidates on the campaign trail, and scholarly experts portray the United States as a fearful nation whose people are worried about the next terrorist attack and are willing to sacrifice civil liberties at home and support costly and aggressive policies abroad (Ackerman 2007...

Analysis of genomes evolving by inversions leads to a combinatorial problem of sorting by reversals studied in detail recently. Following a series of work recently, Hannenhalli and Pevzner developed the rst polynomial algorithm for the problem of sorting signed permutations by reversals and proposed an O(n 4) implementation of the algorithm. In this paper we exploit a few combinatorial properti...

The present study employed the Delphi procedure to examine the similarities and differences in the theory and practice of structural and strategic family therapy. A three-phase Delphi questionnaire was sent to a national panel of knowledgeable structural and strategic therapists, who were asked to identify and reach a consensus of opinion about items they thought important to a profile of eithe...

Individual differences in skill acquisition are influenced by several architectural factors. According to Ackerman’s theory, general intelligence, speed of proceduralization and psychomotor speed influence different stages of skill acquisition. The ACT-R cognitive architecture allows for direct testing of this theory by manipulating parameters that correspond to these factors. The present study...

During the Summer of 1997 Nomad a planetaryrelevant mobile robot, was driven via satellite link for more than 125 miles in the Atacama Desert of Chile by novice operators in North America, demonstrating many technologies relevant to robotic exploration of the planets. An innovative \transforming" chassis was demonstrated which uses a simple linkage to change the footprint of the vehicle from a ...

Interstitial granulomatous dermatitis is a rare entity first described by Ackerman et al. in 1993. We described a 57-year-old female, with a long-standing history of rheumatoid arthritis, presenting with symmetric violaceous to erythematous indurated papules and nodules on her buttock and medial thighs arranging in an arciform fashion for more than three months. Pathologically, it showed palisa...

Over the past decade or so the evolution and equilibria of persistent decks of stratocumulus climatologically clinging to the edge of summertime subtropical highs have been an issue of increased scientific inquiry. The particular interest in the microphysical structure of these clouds stems from a variety of hypotheses which suggest that anthropogenic influences or biogenic feedbacks may alter ...

People chose different strategies for performing tasks, and that choice often plays a key role in performance. We investigate the use and evolution of strategic behavior in the Kanfer-Ackerman Air Traffic Controller c task, a fast-paced, dynamic task. We present strategies in two dimensions for one aspect of the task, examine how people use them and switch between them, and how their use relate...
