ABSTRACT Current research on consumer health information searching focuses on users' adoption of sources or their behaviors of using a specific system. Yet, few studies take a holistic perspective to examine health information searching as a process that takes place in real life settings

can yield benefits on three counts. First, it can provide a real-life test of current theory and research on intrinsic and extrinsic motivation. Second, because the proposed model deals with an unfolding sequence, it may serve to integrate existing knowledge on intrinsic and extrinsic motivation

Our students are highly competent in the technical area, but have little training in the non-tecnical area. This paper describes a course that is designed to increase the students ability to apply their technical skills in a professional way. Projects with real, low in IT skills, users are used

We present an approach to estimate and track 2D upper body poses of persons who are having a meal in videos with highly challenging uncontrolled imaging conditions. We employ a probabilistic model that represents the body as a kinematic tree, and perform inference in this kinematic tree model using particle ltering, and also estimates self-occlusions. Our approach is evaluated with 7 di erent videos, in which di erent persons with di erent types of clothing, orientation can be seen, su ering from various degrees of motion blur. The evaluation shows that our approach can deal with complex data, and successfully tracks upper bodies with a lot of self-occlusions. 1

Abstract The present research investigated whether assessing adolescent elite athletes ’ motivational profiles at the beginning of the season would allow us to predict their subsequent performance over the course of a competitive season. In two studies, athletes completed the French ver-sion of the Sport Motivation Scale (Brière et al., Int J Sport Psychol 26:465–489, 1995) at the beginning of the season. Objective levels of performance were recorded for the following season, as well as for the season prior to ques-tionnaire completion. In Study 1, the sample comprised a total of 170 French junior national tennis players (M = 13.42 years). Results revealed the presence of a four-cluster solution, reflecting different levels of autono-mous and controlled motivations. Results revealed that controlling for past performance, athletes with the least self-determined motivational profile obtained lower levels of subsequent tennis performance than those in the three other (more self-determined motivational) clusters. In Study 2, there were a total of 250 French junior national fencers aged 15 years. Results revealed a three-cluster solution very similar to that of Study 1. In addition, in line with Study 1, results revealed that the least self-determined motivational profile led to the lowest level of performance. Overall, these findings suggest that cluster analysis is useful in the understanding of the complex relationship between motivation and performance in elite sport.

Introduction: Varenicline has a significant impact on the ability to quit smoking. However, patients may have side effects similar to nicotine withdrawal symptoms. The aim of this study was to evaluate the effectiveness of varenicline in monotherapy or in combined therapy with bupropion and/or serotonin reuptake

. The TYNERGY study aimed to further evaluate the effects of natalizumab treatment on MS-related fatigue. In this one-armed clinical trial including 195 MS patients, natalizumab was prescribed in a real-life setting, and a validated questionnaire, the Fatigue Scale for Motor and Cognitive functions (FSMC
