Synchronized action is considered as a manifestation of shared skill. Most synchronized behaviors in humans and other animals are based on periodic repetition. Aperiodic synchronization of complex action is found in the experimental task of synchronous speaking, in which naive subjects read a common text in lock step. The demonstration of synchronized behavior without a periodic basis is presen...

The paper presents a model of technology adoption with endogenous supply of human capital. I investigate the effects of skill bias technical change in the frontier economies on the evolution of output, the quantity and quality of human capital in the adopting countries. The framework introduces a novel feature by connecting the direction of technology adoption to a sequential process of skill a...

A new approach to skill acquisition in assembly is proposed. An assembly skill is represented by a hybrid dynamic system where a discrete event controller models the skill at the task level. The output of the discrete event controller provides the reference commands for the underlying robot controller. This structure is naturally encoded by a hidden Markov model (HMM). The HMM parameters are ob...

To realize the harmonious cooperation with the operator, the man-machine cooperative system must be designed so as to accommodate with the characteristics of the operator’s skill. One of the important considerations in the skill analysis is to investigate the switching mechanism underlying the skill dynamics. On the other hand, the combination of the feedforward and feedback schemes has been pr...

Global skill shortages are reported in many occupations. Existing strategies for addressing skill shortages are not successful and, as a result, skill shortages are an intractable problem. A new strategy, real-time communication of skill knowledge without human instructors, has the potential to bring about radical reductions in skill shortages. The goal of the study reported in this VTT Working...

Interruptions are prevalent phenomena in modern working environments; yet, few interruption studies have been conducted on different types of human tasks. A study using computer-based human behavior tasks was carried out to investigate the effects of interruptions with 4 different primary-interrupting task sets. The tasks used in this study were determined by cognitive and motor skill processes...

We examine the ability of male immigrants to transfer their occupational human capital using information from the O*NET and a unique dataset that includes both the last source country occupation and the first four years of occupations in Canada. We first augment a model of occupational choice and skill accumulation to derive predictions about the cross-border transferability of occupational hum...

BEKO-SMS is a knowledge-based skill management system that combines project planning and human resource management. Application and system functions model specific skills and relationships used in a particular project. The definition of skills, skill trees, skill updating and other processes form the basis for the success factors of the SMS. We conclude that efficient project resource planning ...
