Items addressed the three central laboratory tasks within each discipline, namely: RA (19 items for biochemistry and 29 items for cell biology), DM (20 items for biochemistry and 13 items for cell biology), and LT (33 items for biochemistry and 21 items for cell biology).
We removed 15 items for biochemistry and 28 items for cell biology, yielding item difficulties (and discrimination parameters) ranging between.21 and.55 (.15 and.78, respectively) for biochemistry and.22 and.50 (.20 and.81, respectively) for cell biology (see Additional file 3: Table S1).
ExC10 showed a similar but more pronounced pattern of decline and contained an excess of genes with GO items for mitosis, cell cycle and cell division (P<10−7 for each category), reflecting the decreasing activity of these functions as the cell model terminally differentiated.
Synonym judgment was split into 3 conditions (20 items for each cell) varying the type of word (20 high-frequency concrete words, 20 low-frequency concrete words, and 20 abstract/low imageability words) but matching decision times.
Also, some chromosomes dominated some GO items, for example, Chr05 and Chr26 dominated the four major items of cell component (see Additional file 7).
In this context, the tasks within each cell become items for performance evaluation that can contribute to an effective, comprehensive after-action report.
The big mixing bowl can be home for important everyday items including cell phones or iPod chargers––anything you'll need on the go and fast.
This is suitable for a range of items including cell phones, music and video widgets, battery chargers, etc.
Item difficulties (and discrimination parameters) ranged between.14 and.60 (.11 and.60, respectively) for biochemistry, and between.04 and.61 (−14 and.61, respectively) for cell biology.
They wanted to know what was going on, and fired off questions at him: "What's going on here?", "Is there a black market in knickers?", "Where did you get them?" He refused to answer, so he was hauled in front of the governor for having unauthorised items in his cell.
