The long hours, the quantity and difficulty of the work, and the pressure to excel are a recipe for frayed nerves, shortened tempers and durable frustrations.
Last week, the New York State Education Department took steps to ease some testing requirements after weeks of criticism from parents and teachers about the quantity and difficulty of the exams.
The resulting value, called inter-annotator agreement (IAA) or inter-coder agreement score is useful to assess how well the task is defined, how consistent the annotations are and it helps to quantity the difficulty of the annotation process.
Aspects of sleep raised by FM patients included poor sleep quality and insufficient quantity including difficulty with falling asleep, getting comfortable, and staying asleep; restlessness; light sleep; not feeling rested upon awakening; and difficulty starting the day.
In cases in which there appear to be no conservation laws governing the explanatorily relevant property (i.e., cases in which the explanatorily relevant variables are not conserved quantities) this difficulty seems even more acute.
We excluded 717 participants from the analysis who had prevalent diabetes at the baseline survey conducted between 1999 and 2000, or those who did not report the quality or quantity of sleep (difficulty initiating sleep, difficulty maintaining sleep, and duration of sleep) at baseline.
CO was promoted in quantity reflecting the difficulty of its oxidation over these zeolite catalysts.
By contrast, current models operate with unknown specificity, and adjusting an unknown quantity presents a difficulty.
Consistent with the findings of previous research on the context of deliberate self-harm of adolescents [ 16- 18], it was found that parental well-being was strongly correlated with the quantity and magnitude of difficulties encountered by the child, as reported by the parent, i.e., parental well-being was lower when child difficulties were greater.
As pointed out in, e.g., [6, 7], a joint maximum likelihood (ML) estimation of all these unknown quantities would encounter computational difficulties and convergence (or even existence) issues.
