Determining BPL Status Some Methodological Improvements

Marital status and suicide: some common methodological problems.

EDITOR,—In a recent paper published in this journal, Kposowa reported that divorced and separated men had a higher risk of suicide than married men. Men and women of other unmarried status reportedly did not suVer any excess risk of suicide in comparison with their married counterparts. We have some reservation about the findings, and wish to point out two methodological problems that may have ...

Elutriation: Theoretical Considerations and Methodological Improvements

The conventional elutriation method used for separating meiofauna and sediment yields insufficiently correct quantitative results. A critical evaluation of the physical background of this method leads to the construction of a differently shaped separation funnel and to improvements allowing better controlled, gradual variations in waterflow velocity and sieve mesh sizes. Comparative tests of th...

Some improvements in fuzzy turing machines

In this paper, we improve some previous definitions of fuzzy-type Turing machines to obtain degrees of accepting and rejecting in a computational manner. We apply a BFS-based search method and some level’s upper bounds to propose a computational process in calculating degrees of accepting and rejecting. Next, we introduce the class of Extended Fuzzy Turing Machines equipped with indeterminacy s...

Some Methodological Suggestions

Rather than providing a big picture about monetary policy, I appoint myself as a discussant of the two papers presented in this session, one on inflationary expectations by Galati, Poelhekke, and Zhou, and the other on the recent commodity boom by Erceg, Guerrieri, and Kamin. For each of the two papers, which I take to be the best industry practice, I will suggest an alternative methodology. My...
