Background: Expert knowledge may compensate for age-related declines in basic cognitive and sensory-motor abilities in some skill domains. We investigated the influence of age and aviation expertise (indexed by Federal Aviation Administration pilot ratings) on longitudinal flight simulator performance. Methods: Over a 3-year period, 118 general aviation pilots aged 40 to 69 years were tested an...

UNLABELLED Endoscopic forehead lift (EFL) represents a significant progress, even replacing the classic coronal and pretriquial techniques. AIM To demonstrate a series of cases and to evaluate results and complications with EFL in the Department of Otorhinolaryngology of the Federal University of Uberlândia. MATERIALS AND METHODS From January 2001 to January 2004, 67 patients were submitted...

Children's ability to deceive was examined in order to determine whether they are able to hide their emotional expression intentionally. Three-year-oids were instructed not to peek at a toy while the experimenter left the room. When asked, the great majority either denied that they peeked or would not answer the question. Facial and bodily activity did not differentiate the deceivers from the t...

Y2K presented a formidable (albeit welldefined) challenge: find the date problems and fix them (see our “Congratulations” in the accompanying sidebar). Post-Y2K presents a more formidable challenge: a...

Mainstream Information Technology professionals have misunderstood the Pick environment for many years. The Pick environment has been conceived, designed and built with business solutions as its key driver. At its heyday there were over 3,000 business applications available across a very wide range of hardware platforms supporting from 1 to thousands of real time users. The tentative economic r...

Fatigue is a recognised problem in the transport industry. It has been attributed to two main influences: time of day and the time since last sleep. While the role of these two influences in producing fatigue is not disputed, there is less agreement on how they interact with one another. The aim of this study was to examine the relative effects of time of day and sleep deprivation on fatigue an...

Prior studies have shown that the IT innovation capability, a company's ability to innovate systematically with IT, is not easily replicated (persistent), and the persistence tends to be more pronounced during periods when economy-wide IT budgets are declining (hard IT budgets), such the post-Y2K period. Building on resource based view we argue that companies that systematically innovate with I...

We examine the state of game theory. Many important questions have been answered, and game theoretic methods are now central to much economic investigation. We suggest areas where further advances are important, and argue that models of learning and of social preferences provide promising routes for improving and widening game theory’s predictive power, while preserving the sucesses of existing...
