OBJECTIVES We investigated how fluctuations and linear changes in health and cognitive resources influence the motivation to engage in complex cognitive activity and the extent to which motivation mediated the relationship between changing resources and cognitively demanding activities. METHOD Longitudinal data from 332 adults aged 20-85 years were examined. Motivation was assessed using a co...

The purpose of this factorial study was to establish normative data for the Italian version of the Communication Attitude Test (CAT) in order to determine whether or not the speech-associated attitude reported by Italian children who stutter (CWS) differs significantly from that of their nonstuttering peers (CWNS). Toward this end, the Italian CAT was administered to 149 CWS and 148 CWNS betwee...

Software Product Line has proved to be an effective approach to benefit from software reuse. Configuration management, an integral part of any software development activity, takes on a special significance in software product line context. This is due to the special property of software product line, in which the core assets are shared by all products. In this paper, we compare the existing con...

a tandem agv configuration connects all cells of a manufacturing area by means of non-overlapping, sin-gle-vehicle closed loops. each loop has at least one additional p/d station, provided as an interface between adjacent loops. this study describes the development of three tabu search algorithms for the design of tandem agv systems. the first algorithm was developed based on the basic definiti...

in 2005, a. abdollahi and a. rejali, studied the relations betweenparadoxical decomposition and configuration for semigroups. in thepresent paper, we introduce one other concept of amenability typeon semigroups and groups which includes amenability of semigroupsand inner-amenability of groups. we have extend the previous knownresults to semigroups and groups satisfying this concept.

Structure-based configuration models describe commonality and variability as well as restrictions within and between components of a product domain. Innovation in the development of products drives the development of new components and adaptation of existing components. As a consequence of evolution, the configuration model has to evolve in parallel with its referants in the world. A side effec...

FREESURFER VS MANUAL TRACING: DETECTING FUTURE COGNITIVE DECLINE IN HEALTHY OLDER ADULTS AT-RISK FOR ALZHEIMER’S DISEASE Alissa M. Butts, M.S. Marquette University, 2013 Alzheimer’s disease (AD) is a neurodegenerative pathological process that is thought to begin years prior to observable symptom onset. The hippocampus appears to be particularly vulnerable to the underlying brain pathology of A...

Methods: Individuals were recruited from two longitudinal cohort studies—the Washington Heights and Inwood Columbia Aging Project (WHICAP; population-based) and the Predictors Study (clinic-based)—and were followed for an average of 4 years. Three samples of participants diagnosed with AD, with diverse demographic characteristics and baseline cognitive functioning, were studied: 1) 199 (48%) of...

Background: Many observational studies have shown a protective effect of physical activity on cognitive ageing, but interventional studies have been less convincing. This may be due to short time scales of interventions, suboptimal interventional regimes or lack of lasting effect. Confounding through common genetic and developmental causes is also possible. Objectives: We aimed to test whether ...
