In deciding on a student's grade in a class, an instructor generally needs to combine many individual grading judgments into one overall judgment. Two relatively common numerical scales used to specify individual grades are the 4-point scale (where each whole number 0-4 corresponds to a letter grade) and the percent…

We developed an automated 2-tiered Fuhrman’s grading system for clear cell renal cell carcinoma (ccRCC). Whole slide images (WSI) and clinical data were retrieved for 395 The Cancer Genome Atlas (TCGA) ccRCC cases. Pathologist 1 reviewed and selected regions of interests (ROIs). Nuclear segmentation was performed.…

'Peng-Wei Zhang' 'Upaka Rathnayake'] This study proposes a new method to evaluate the effectiveness of orebody grade estimations, drawing upon the analysis of existing evaluation methods for grade estimation. This new approach addresses factors such as uneven sampling and asymmetric estimation range, which are…

Instilling good laboratory working attitudes in students is a difficult but very important task, especially in the first level courses. The introduction of a grade, based on the observation of work practices during laboratory sessions, can be strongly beneficial towards the acquisition of positive skills covering not…

The mismatch between teenagers’ late sleep phase and early school start time results in acute and chronic sleep reductions. This is not only harmful for students’ learning in the short-term but may impact on students’ career prospects and widen social inequalities. Delaying school start times has been shown to improve…

Elevated concentrations of critical metals (CM) in acid mine drainage (AMD) have been the subject of many studies due to high demand that is only expected to grow. Some, like rare earth elements (REEs) and Co are an essential component to many modern technologies. Previously we developed a CM recovery technique wherein…

Providing consistent summative assessment to students is important, as the grades they are awarded affect their progression through university and future career prospects. While small cohorts are typically assessed by a single assessor, such as the module/class leader, larger cohorts are often assessed by multiple…

Previous research has consistently shown students have higher learning interests attitudes, and motivation toward science in elementary compared to middle and high school. However, the key predictors behind the observed differences in engagement levels across grade levels remain unclear. This study aims to identify the…

Popularized on social media, hand-moldable plastics are formed by consumers into tools, trinkets, and dental prosthetics. Despite the anticipated dermal and oral contact, manufacturers share little information with consumers about these materials. Inherent to their function, moldable plastics pose a risk of dermal and…
