Outcomes assessment: an examination of the ETS major field test and the comprehensive business exam

This study is the first to examine student performance differences between the major field test in business (MFTB) and the comprehensive business exam (CBE). Results reveal students performed at a statistically significant 50.8 percentile ranking on the CBE compared to a 38.0 percentile ranking on the MFTB. Additionally, this study finds that students transferring business core courses with a grade point average (GPA) of 2.5 or lower perform at a statistically significant lower level on both the MFTB and the CBE than those transferring business core courses with GPAs higher than 2.5. These findings have important implications for assessment of learning purposes.

Portable X-ray fluorescence analysis of pesticides in the textile collection at the German Historical Museum,Berlin

The majority of the objects found in the textiles collection at the German Historical Museum in Berlin have been treated with different biocides at various points in the past. Prior to this study, the presence of organochlorinated pesticides in rooms and storage cabinets had already been proven in an analysis of air samples that employed gas chromatography and mass spectroscopy. To estimate the risks these toxins pose to both collections and museum staff, we conducted a field study with the help of a portable X-ray fluorescence spectrometer. In this study, we present an attempt at a reliable quantitative analysis. In addition to chlorine, other potentially hazardous elements such as lead, arsenic, and mercury were found in the majority of the objects. In some cases, however, it has to be taken into account that the detected elements might have originated from manufacturing processes rather than biocide treatments. Such knowledge is a crucial prerequisite to proper risk prediction.
