Persistent coordination patterns in a complex task after 10 years delay

Persistent coordination patterns in a complex task after 10 years delay: subtitle: how validate the old saying "once you have learned how to ride a bicycle, you never forget!".

Motor learning studies have for a long time focused on performance variables (in terms of speed or accuracy) in assessing learning, transfer and retention of motor skills. We argue, however, that learning essentially resides in changes in coordination variables (in terms of qualitative organization of behavior) and that relevant tests for assessing the effectiveness of learning and retention sh...

Security patterns: 10 years later

Reusing time-tested solutions rather than inventing ad-hoc quick fixes is a wellknown security principle. Architectural and design patterns represent proven techniques to package knowledge from software engineering experts in a reusable format. More importantly, the solution proposed by a pattern is known to be sound because it is time-tested—its strengths, weaknesses and possible drawbacks are...

Overcoming spontaneous patterns of coordination during the acquisition of a complex balancing task.

Learning in complex tasks is usually conceived as the problem of mastering the multiple and redundant degrees of freedom of the system. To reduce control requirements, two different strategies are conceivable. The first one consists of a "freezing-freeing" process for most articular joints to reduce the number of active biomechanical degrees of freedom to be managed. The second strategy consist...

The World Health Organization European Health in Prisons Project after 10 years: persistent barriers and achievements.

The recognition that good prison health is important to general public health has led 28 countries in the European Region of the World Health Organization (WHO) to join a WHO network dedicated to improving health within prisons. Within the 10 years since that time, vital actions have been taken and important policy documents have been produced. A key factor in making progress is breaking down t...
