A functional assessment of hand flapping exhibited by a 5-year-old boy was conducted in a general education classroom. After a descriptive analysis ruled out several potential variables maintaining hand flapping, an experimental analysis was used to test the hypothesis that teacher-delivered task demands were functionally related to hand flapping. Results of the experimental analysis were used ...

Phosphogypsum (PG) is a waste product (residue) from the production of phosphoric acid characterized by technologically enhanced natural radioactivity. Croatia's largest PG deposition site is situated at the edge of Lonjsko Polje Nature Park, a sensitive ecosystem possibly endangered by PG particles. This field study investigates two aspects relevant for the general radiological impact of PG: r...

A Comprehensive Health Technology Assessment Framework is presented as a conceptual tool for decision-making about health technologies, including information technologies. The aim of the model is to provide an empirical, evidence-based foundation for health technology decisions. The major framework dimensions are (1) population at risk, (2) population impact, (3) economic concerns, (4) social c...
