i This paper is concerned with two issues:  Do the outcomes of PISA – more particularly the rankings – depend on the items chosen?  Could alternative scaling procedures, produce different outcomes – more particularly the rankings. A careful examination of these two issues is clearly an important activity that should be the focus of rigorous scholarly investigation. Unfortunately this article ...

We have read with interest the study by Messika-Zeitoun et al. 1 showing that using a fixed angle value of 100 provides an accurate estimation of the miral valve area (MVA) by the proximal isove-locity surface area (PISA) method in patients with mitral stenosis (MS). We appreciate the study as a means to make PISA method more popular in assessing the MVA. Although not cited in the article, we a...

The change in the impervious-pervious balance has significantly altered the stream water quality, and thus the threshold of the impervious surface area in the watershed has been an active research topic for many years. The objective of this study is to verify the correlation between impervious surfaces and water quality and to determine the threshold of the percentage of the impervious surface ...

The OECD’s education agenda has been marked since the 1990s by monitoring quality and manufacturing problems solutions for so-called knowledge economy. Among instruments used OECD is “PISA Schools” (Pisa-S), an assessment applied directly to schools worldwide 2011. In Portugal, it was implemented in 2019 under designation of municipalities” (PISA-M), claiming create opportunities collaborative ...
