Who and how many can work from home? Evidence from task descriptions

How many points can be reconstructed from k projections?

Let A be an n-point set in the plane. A discrete X-ray of A in direction u gives the number of points of A on each line parallel to u. We define F(k) as the maximum number n such that there exist k directions u_1,...,u_k such that every set of at most n points in the plane can be uniquely reconstructed from its discrete X-rays in these directions. We establish a mildly exponential lower bound F...

How Many Radical Islamists? Indirect Evidence from Five Countries

High fertility and low market returns to schooling are predicted by a clubgood model of religious sects. We investigate fertility and returns to education among families of graduates of Muslim religious schools in Indonesia, Bangladesh, India, Cote D’Ivoire, and Pakistan. Fertility is significantly higher among these families in all five countries. Returns to education are generally lower among...

Implicit and Explicit Instruction and EFL Learners’ Implicit Knowledge Development: Evidence from Word Monitoring Task

Research on the effect of implicit and explicit instruction on developing learners’ explicit knowledge by the use of measures of explicit knowledge abounds in the literature. However, measuring learners’ implicit knowledge employing fine-grained measures has rarely been the concern of researchers in the field. Therefore, the present study is an attempt to scrutinize the effectiveness of implici...

Learning web-service task descriptions from traces

This paper considers the problem of learning task specific web-service descriptions from traces of users successfully completing a task. Unlike prior approaches, we take a traditional machine-learning perspective to the construction of webservice models from data. Our representation models both syntactic features of web-service schemas (including lists and optional elements), as well as semanti...
