AbstractWe develop a figure of merit for SETI observations which is anexplicitfunction of the EIRP of the transmitters, which allows us to treat sky surveys and targeted searches on the same footing. For each EIRP, we calculate the product of terms measuring the number of stars within detection range, the range of frequencies searched, and the number of independent observations for each star. For a given set of SETI observations, the result is a graph of merit versus transmitter EIRP. We apply this technique to several completed and ongoing SETI programs. The results provide a quantitative confirmation of the expected qualitative difference between sky surveys and targeted searches: the Project Phoenix targeted search is good for finding transmitters in the 109to 1014W range, while the sky surveys do their best at higher powers. Current generation optical SETI is not yet competitive with microwave SETI.

Positive Effect

The current generation is facing a number of challenges related to their future. The education system is looking for adequate ways to change and adaptively focus the learning process. The application of a competency approach in education has a positive effect. The article attempts to explain the essence of the competency approach and its projections in the preparation, education and upbringing of children and students. Basic elements that are leading in organizing the learning process are outlined. Concepts necessary for subsequent theoretical research and methodological formulations are defined.
