LEAP is a coached practice environment that optimizes the learning process by maintaining and consulting a detailed student model. LEAP calculates a student model score for every action, exercise, and topic the student tries, then uses the scores both to provide feedback to the student and to select topics, exercises and actions for the student to practice. Using the student model to focus prac...

Two cognitive-motivational variables that help to solidify drinkers' intentions to drink are their alcohol attentional bias and their maladaptive motivation. The Alcohol Attention Control Training Programme (AACTP) was designed to rectify the former, and the Life Enhancement and Advancement Programme (LEAP) was designed to rectify the latter. The present study used a factorial design to compare...

An important goal of current work in computer-based learning environments is to develop systems that combine the richness and effectiveness of an individually crafted intelligent tutoring system (ITS) with the generality and flexibility of a computer-assisted instruction (CAI) authoring tool. Our effort to achieve this goal is demonstrated in the Learn, Explore and Practice (LEAP) ITS shell and...

The Leap Motion controller is a low-cost, optically-based hand tracking system that has recently been introduced on the consumer market. Prior studies have investigated its precision and accuracy, toward evaluating its usefulness as a surgical robot master interface. Yet due to the diversity of potential slave robots and surgical procedures, as well as the dynamic nature of surgery, it is chall...

what should be done to make ERP a good investment. It is very common, however, for companies to take a big leap of faith with ERP and supply chain management systems. And, unfortunately, more than 90 percent of the companies that have implemented ERP have not had a truly successful implementation the first time around. Despite the recent rash of articles about the limited returns from ERP, howe...

T he aim of this article is to communicate the work of Mikhael Gromov (MG) and its influence in almost all branches of contemporary mathematics and, with a leap of faith, of future mathematics. Because of its length, the article will appear in two parts. It is not meant to be a technical report, and, in order to make it accessible to a wide audience, I have made some difficult choices by highli...

The loss of allograft function in the long term (whatever its pattern over time) not only remains the single major cause of death following lung transplantation but has continued largely unabated since the beginning of the modern era in the 1980s [1–3]. As obliterative bronchiolitis (OB) was the most common histopathological finding on biopsy of the failing lung allograft, this feature became t...

In this paper we shall introduce a new electronic payment concept based on the popular direct debit payment model, entitled periodical payments. The direct debit model currently in use online is neither secure nor flexible, and requires a leap of faith by the customer who must trust the merchant to behave honestly. Electronic direct debit request (DDR) forms are not signed by both parties in a ...

Understanding the mechanisms underlying acute coronary syndromes (ACS) depended for decades on autopsy studies. The limitations of postmortem studies include death as an inclusion criterion, biasing the studies toward events with fatal outcomes. The more numerous nonmortal events comprise a sizable but heretofore largely hidden denominator of uncertain magnitude. To gain insight into the underl...

BACKGROUND The recent advances in the psychooncological and psychoneuroimmunological investigations of cancer patients has allowed the rediscovery of the importance of spiritual faith in influencing the clinical course of neoplastic disease, not only in terms of supportive care but also as a potential prognostic variable. MATERIALS AND METHODS Clinical criteria were worked out to explore the ...
