Motivating students is a major issue for current Intelligent Tutoring Systems. Videogames are known to have a very addictive effect on their users. We have the intuition that such a phenomenon is partially due to the autonomy support videogames provide to their user. In fact, modern theories of motivation such as the Self Determination Theory (SDT) have shown the positive motivational impact of...

Although brokers’ trading is endemic in securities markets, the form of this trading differs between markets. Whereas in some securities markets, brokers may trade with their customers in the same transaction (simultaneous dual trading or SDT), in other markets, brokers are only allowed to trade after their customers in a separate transaction (consecutive dual trading or CDT). We show theoretic...

The state description and corresponding dynamic Bayesian network are shown in Table 1 and Figure 1. In the paper we mentioned that ms denotes the state of task i. To make this more detailed, we factorms into a tuple (m i r,m i d,m i s,m i c). The variable mr encodes the release time of task i. The variable md represents the number of steps task i can still be postponed, which can be used to enc...

OBJECTIVES The current article explores age differences in skill acquisition. We validated strategy self-reports, evaluated whether eye movements may be automatic as well as information seeking, and considered the contribution of eye movements to age differences in overall performance. METHODS Young and older adults performed the noun-pair lookup (NP) task. With practice, pairs (e.g., IVY-BIR...

In this paper, a new method of fuzzy decision trees called soft decision trees (SDT) is presented. This method combines tree growing and pruning, to determine the structure of the soft decision tree, with re4tting and back4tting, to improve its generalization capabilities. The method is explained and motivated and its behavior is 4rst analyzed empirically on 3 large databases in terms of classi...

Men's role in HIV prevention is pivotal to changing the course of the epidemic. Men's barriers toward participation in Prevention of Mother-to-Child Transmission (PMTCT) have not been adequately documented. This study is therefore designed to determine men's level of awareness and barriers to their participation in PMTCT programmes in Osogbo, Nigeria. This study was a descriptive qualitative on...

ion While the coverage-driven design validation is getting popular, it would be more convenient for users to have an automatic generator that can generate the input patterns to satisfy the coverage requirements. The symbolic techniques can be used to generate the desired input patterns easily for a specific state transition in a FSM. However, it is not practical for real designs because the mem...

Crowd work has emerged as a new form of digital gainful employment that changes the nature of work. However, an increasing number of people perform certain tasks in the crowd and start to identify with this work. In this paper, we outline our research in progress which is concerned with the effects of work characteristics in crowd work that have impact on the individual’s identification. Thus, ...

Due to increasing demands from companies and standardisation bodies, Telelogic AB and the University of L ubeck started a research and development project in October 1996 which aims at improving the validation and, especially, the automatic test generation facilities of the SDT/ITEX tool set. The project is driven by practical experiences and practical needs, but also takes care of research res...

Descriptive statistics for the Neonatal Intensive Care Unit Network Neurobehavioral Scale summary scores are provided for a sample of 125 full-term, healthy 1- to 2-day-old infants. The study sample is described, including demographic characteristics and infant and maternal medical characteristics. Descriptive statistics and percentiles are provided for the Neonatal Intensive Care Unit Network ...
