Automaticity and skill are closely related but are not identical. Automatic processes are components of skill, but skill is more than the sum of the automatic components. Automaticity and skill are similar in that both are learned through practice; this has implications for (1) current studies of the co-occurrence of properties of automaticity, (2) the relation between multiple resources and au...

BACKGROUND Movement skill competence (e.g. the ability to throw, run and kick) is a potentially important physical activity determinant. However, little is known about the long-term impact of interventions to improve movement skills in early childhood. This study aimed to determine whether intervention preschool children were still more skill proficient than controls three years after a 10 mont...

Decadal climate predictions may have skill due to predictable components in boundary conditions (mainly greenhouse gas concentrations but also tropospheric and stratospheric aerosol distributions) and initial conditions (mainly the ocean state). We investigate the skill of temperature and precipitation hindcasts from a multi-model ensemble of four climate forecast systems based on coupled ocean...

We introduce CST, an algorithm for constructing skill trees from demonstration trajectories in continuous reinforcement learning domains. CST uses a changepoint detection method to segment each trajectory into a skill chain by detecting a change of appropriate abstraction, or that a segment is too complex to model as a single skill. The skill chains from each trajectory are then merged to form ...

BACKGROUND A competitive Carrick Institute Competitive Grant (CG7-523) was obtained to explore what skills were taught and what assessment of practice approaches were used in nursing programmes in Australia. The intention was twofold; firstly to identify what skills were being taught which would contribute to the development of an assessment of practice toolkit for eligibility to practice progr...

We tested the assumptions of Attentional Control Theory (ACT) by examining the impact of anxiety on anticipation using a dynamic, time-constrained task. Moreover, we examined the involvement of high- and low-level cognitive processes in anticipation and how their importance may interact with anxiety. Skilled and less-skilled tennis players anticipated the shots of opponents under low- and high-...

The aim of the present study was to conduct within-gymnast analyses of biological movement variability in impact forces, elbow joint kinematics and kinetics of expert gymnasts in the execution of the round-off with different hand positions. Six international level female gymnasts performed 10 trials of the round-off from a hurdle step to a back-handspring using two hand potions: parallel and T-...

Medical curriculum revisions all over the world in the last 20 years have increased the number of teaching hours in communication skills. This article describes a concrete communication skills teaching programme focused on general practice. Since the spring of 1992, more than 2,000 physicians from Denmark, Sweden and Finland have attended courses within this programme in Kalymnos, Greece. The t...

In this paper, we consider the Multi-skill Crew Rostering Problem. We propose a constraint programming approach based on constraint set variables. We prove that this approach yields an exponential factor improvement in the worst-case search space over the conventional constraint programming approach. To handle preferences, we follow a ''relax and enrich'' scheme of Schmidt. Using our approach, ...
