The measurement of educational inequality : achievement and opportunity [PDF]

This paper proposes two related measures of educational inequality: one for educational achievement and another for educational opportunity. The former is the simple variance (or standard deviation) of test scores.

Determination of ADP/ATP translocase isoform ratios in malignancy and cellular senescence

Molecular Oncology, EarlyView.
The individual functions of three isoforms exchanging ADP and ATP (ADP/ATP translocases; ANTs) on the mitochondrial membrane remain unclear. We developed a method for quantitatively differentiating highly similar human ANT1, ANT2, and ANT3 using parallel reaction monitoring. This method allowed us to assess changes in translocase levels during cellular

Loss of proton‐sensing GPR4 reduces tumor progression in mouse models of colon cancer

Molecular Oncology, EarlyView.
G protein‐coupled receptor 4 (GPR4) is a pH‐sensing receptor activated by acidic pH. GPR4 expression is increased in patients with inflammatory bowel disease who are at high risk of developing colorectal cancer. In mouse models, loss of GPR4 attenuated tumor progression. This correlated with increased IL2 and natural killer cell activity.

Observing the World Through Your Own Lenses – The Role of Perceived Adaptability for Epistemological Beliefs About the Development of Scientific Knowledge

Frontiers in Psychology, 2018
Students are exposed to vast amounts of information and knowledge that is rapidly changing. This exposure requires them to be adaptive, that is, to constantly adjust their thinking, behavior, and even their affect to successfully solve information-rich ...

Measurement in education [PDF]

, 2018
Data is the new gold. In education, this debate focusses specifically on test scores; whether used for evaluating schools or teachers, assessing social mobility or investigating children’s skill development. However, the perfect data do not exist. The value of any data analysis depends crucially on how the data were collected, which individuals are ...
