Abstract

College grade point average (GPA), a linear combination of assigned grades from different courses, is widely known to be an imperfect measure of student achievement. This unreliable measure decreases the predictive validity of college admission tests. Research has shown that adjusting course grades for differential grading practices improves predictive validity. Relative rankings of students on adjusted college GPAs are also more consistent with their course grade standings. These findings were replicated with course grade data from consecutive cohorts of two universities using four polytomous item response theory (IRT) and three linear models. In study 1, data were available for 1,255 students in the 1995 cohort and 1,796 students in the 1996 cohort. In the second study, data were available for 1,823 students for 1995 and 1,879 students for 1996. As had been done in previous studies, course parameter estimates and regression weights were cross-validated. Both same-sample and cross-validated alternative measures showed improvement over simple GPA. The rating scale and partial credit IRT models excelled on multiple correlations with admission test scores. The graded response IRT model was the most unstable across cohorts. Implications of these findings and limitations of the studies are discussed. An appendix shows formulas and number of course parameters for the models selected.

Abstract

Background: The knowledge base on physical activity and sedentary behaviour in adults with Down syndrome (DS) may advance by accelerometer calibration studies. This study aimed to develop cut‐points for sedentary behaviour and moderate‐to‐vigorous physical activity (MVPA) for adults with DS based on output from accelerometers worn on the dominant and non‐dominant hips. Methods: Sixteen adults with DS (10 men; age 31 ± 15 years) performed 12 tasks including sedentary behaviours and physical activities. We obtained metabolic equivalents (METs) with indirect calorimetry and vector magnitude (VM) output from triaxial accelerometers (wGT3X‐BT, ActiGraph) worn on the dominant and non‐dominant hips. Receiver operating characteristic curves were used to identify optimal VM cut‐points that maximised sensitivity and specificity. Results: Overall classification accuracy was very high (area under the ROC curve: 0.95 and 0.92 for sedentary and MVPA models, respectively). For the non‐dominant hip, the optimal VM cut‐points were (1) sedentary behaviour ≤236 counts·min−1 and (2) MVPA ≥2167 counts·min−1. For the dominant hip, optimal cut‐points were (1) sedentary behaviour ≤243 counts·min−1 and (2) MVPA ≥2092 counts·min−1. Conclusions: The presented VM cut‐points for sedentary behaviour and MVPA for adults with DS had high classification accuracy. There were small differences in accelerometer cut‐points between the dominant and non‐dominant hip. [ABSTRACT FROM AUTHOR]

Abstract

Background H1 receptor antagonists are commonly used for the treatment of allergic diseases. The aim of this study was to find out, if antihistaminic compounds like mepyramine have the ability to influence the activity of antibacterials. Therefore, the checkerboard method was chosen to detect these possible effects in vitro. Studies were performed with two different Escherichia coli (E. coli) strains as test microbes, treated with antibacterials in combination with mepyramine. Results The minimum inhibitory concentration (MIC) of E. coli ATCC® 25922™ and E. coli PIG 01 was reduced by combinations of the tested antibacterials with mepyramine. Conclusions These results have to be confirmed in vivo, before the use of antihistamines should be considered as potential way to minimize the amount of used antibacterials for treatment of E. coli infections.
