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...

We evaluate the relationship between job proximity and male joblessness at the neighborhood level in Cleveland and Milwaukee. Using two tract-level measures of proximity to employment (i.e., physical distance and commute time), we Žnd mixed evidence for the spatial mismatch hypothesis. As expected, we Žnd that predominantly black neighborhoods in both cities have higher rates of male joblessnes...

Development of cognitive architecture where the agents at different levels exhibit different levels of thinking. The paper primarily focus on building the skill tree at the learning layer of the architecture. These include the discovery of one’s own body, including its structure and dynamics. Also the acquisition of associated cognitive skills such as self and non-self-distinction. This can be ...

There is a body of work that suggests that those elements of the cognitive architecture responsible for processing, on the one hand, visual information (essentially visual properties of objects), and, on the other hand, spatial information (spatial relationships between objects), may compete with each other for resources. In this paper, we explore whether and to what degree the processing of vi...

Old age is associated with poorer movement skill, as indexed by reduced speed and accuracy. Nevertheless, reductions in speed and accuracy can also reflect compensation as well as deficit. We used a manual tracing and a driving task to identify generalized spatial and temporal compensations and deficits associated with old age. In Experiment 1, participants used a hand-held stylus to trace a pa...

Although it is generally acknowledged that the practical predictability at smaller scales may be limited, output of high-resolution morphodynamic area models is mostly presented at the resolution of the computational grid. The sopresented fields typically are realistic looking, but not necessarily of similar quality at all spatial scales. Unfortunately, commonly used single-number validation me...

Low-skill workers are comparatively immobile. When labor demand slumps in a city, college-educated workers tend to relocate whereas non-college workers are disproportionately likely to remain to face declining wages and employment. A standard explanation of these facts is that mobility is more costly for low-skill workers. This paper proposes and tests an alternative explanation, which is that ...

Navigating is a complex cognitive task that places high demands on spatial abilities, particularly in the absence of sight. Significant advances have been made in identifying the neural correlates associated with various aspects of this skill; however, how the brain is able to navigate in the absence of visual experience remains poorly understood. Furthermore, how neural network activity relate...

In this paper, some HAM (Human Adaptive Mechatronics) research results on operator skill evaluation, operation assistance, identification of operator's dynamics, skill acquisition, and coupling phenomenon in bimanual operation are presented at first. Then the bimanual operation is discussed in detail. The phenomenon of spatial coupling between two different tasks performed by two hands respecti...
