This paper assesses the impact of investmentand education-specific technical change on occupational transition and the skill premium in a model with human capital. In this framework, human capital augments labour productivity and also facilitates the transition to skilled employment. In line with empirical evidence, this setup predicts that an increase in the productivity of physical capital (i...

Historically, industrialization has been associated with falling relative returns to skills. This fact is at odds with most unified theories of industrialization, which tend to imply rising skill premia as natural concomitants to economic growth. This paper develops a very simple model of historical growth to help solve this puzzle. Assuming that human capital is both a consumption good and an ...

Categorization is a vitally important skill that people use every day. Early theories of category learning assumed a single learning system, but recent evidence suggests that human category learning may depend on many of the major memory systems that have been hypothesized by memory researchers. As different memory systems flourish under different conditions, an understanding of how categorizat...

objectives: our objective was to design an rct in order to assess the effects of adding a brief skill-based psychoeducation (pe) to routine needle and syringe programs to reduce injection and high risk sexual behaviors associated with human immunodeficiency virus (hiv) infection among referrals of drop-in centers (dics). method/design: this was a randomized control trial with the primary hypoth...

Background: It is trivial that the usefulness of a technology depends on the skill of the user. Several studies have reported an interaction between skill levels and different technologies, but the effect of skill is, for the most part, ignored in empirical, human-centric studies in software engineering. Aim: This paper investigates the usefulness of a technology as a function of skill. Method:...

Development of skilled robotics draws clues from model-based theories of human motor control. Thus, a comprehensive anthropomorphic background is given in the introductory part of the paper. Skills in robotics are viewed as a tool for fast and efficient real-time control that can handle complexity and nonlinearity of robots, generally aiming at robot autonomy. Particularly, a skill of redundanc...

This paper examines the cross-country income and welfare consequences of trade-induced human capital (dis-)accumulation. The model is based on heterogeneous workers who make educational decisions in the presence of complete markets. When such heterogeneous workers invest in schooling, high type agents earn a surplus from their investment. In the presence of cross-country differences in skill-au...

We present a framework for learning skills from novel types of demonstrations that have been shown to be desirable from a human-robot interaction perspective. Our approach –Keyframe-based Learning from Demonstration (KLfD)– takes demonstrations that consist of keyframes; a sparse set of points in the state space that produces the intended skill when visited in sequence. The conventional type of...

Motor skill is one of the most basic intelligent activities by human beings. We can acquire various high level physical skills such as throwing, typewriting, playing musical instruments and so on. However, it is di cult to understand the mechanism of the skill by experts. Here, we discuss motor skill in terms of dynamic constraint satisfaction including motion integrity constraint (MIC). Some b...
