It is important for clinicians to understand how adults who stutter construct who they are, i.e. their self-identity, in order to offer personally meaningful interventions. Early research on stuttering and self-concept provided initial knowledge, but there has been a dearth of further research in this field. This article, the third in a series of papers emanating from a doctoral study, provides...

"Civilizations" and "world systems" are alternative labels for the largest macropolitical entities that have existed in human history. These historical civilizations/world systems may be seen as having two polar types of power structure, the "states system" and the "universal empire." Each form has certain characteristic accompaniments, which may promote it, be promoted by it, or both. For stat...

Problems of coordinated motion of vehicular formations have received much attention lately, especially in the areas of formation flight and so-called vehicular platoons. We investigate fundamental limitations that the use of only local feedback control has on the coherence of large formations that are subjected to stochastic disturbances. The notion of coherence translates roughly into how clos...

Loose, fibrillar, spherical structures have been observed during recent years in interphase nuclei of both animal and plant cells. These nuclear formations have been referred to as karyosomes, fibrillar bodies, micropuffs and centromeres. In order to gain further information on the nature of these structures, a cytochemical and radioautographic investigation was undertaken using plant meristema...

One potentially cost-effective approach to harvesting solar power from space is the use of thousands of individual robots moving in formation, each with a piece of solar panel attached, to form a solar panel array. In previous work, we demonstrated an algorithm that treats a group of robots as a 1-dimensional cellular automaton, which is able to establish formations defined by a single mathemat...

Based on the analysis of currently existing methods interpreting results research into gas-saturated and gas-condensate formations in case stationary or non-stationary filtration, direction solving this problem is indicated specifically for high-flow wells using new calculation method. Since method has not existed traditional way until now, one based an original unconventional approach to initi...

In this paper, we provide a theoretical framework that consists of graph theoretical and Lyapunov-based approaches to stability analysis and distributed control of multi-agent formations. This framework relays on the notion of graph rigidity as a means of identifying the shape variables of a formation. Using this approach, we can formally define formations of multiple vehicles and three types o...
