BACKGROUND AND PURPOSE In the United States and elsewhere, stroke performance measures have been developed to monitor and improve the quality of care. The process by which these measures are developed, implemented, and evaluated is complex, evolving, and not widely understood. We review the methodological development of stroke performance measures in the United States. METHODS A literature se...

IMPORTANCE Dermoscopy permits the detection of early-stage melanomas but is difficult to learn. It is important to develop effective teaching methods. Spaced education is a methodology within the field of adaptive learning that uses online tools to reinforce long-term retention. OBJECTIVES To determine whether a spaced education dermoscopy module improved dermoscopy skills in the continuing m...

Though popular, there is little agreement on what whole-body vibration (WBV) parameters will optimize performance. This study aimed to clarify the effects of age, sex, hertz and time on four physical function indicators in community-dwelling older adults (N = 32). Participants were exposed to 2 min WBV per session at either 2 Hz or 26 Hz and outcome measures were recorded at 2, 20 and 40 min po...

CONTEXT Nutrition knowledge can influence dietary choices and impact on athletic performance. Valid and reliable measures are needed to assess the nutrition knowledge of athletes and coaches. OBJECTIVES (1) To systematically review the published literature on nutrition knowledge of adult athletes and coaches and (2) to assess the quality of measures used to assess nutrition knowledge. DATA ...

Six-Sigma has some measures which measure performance characteristics related to a process. In most of the traditional methods, exact estimation is used to assess these measures and to utilize them in practice. In this paper, to estimate some of these measures, including Defects per Million Opportunities (DPMO), Defects per Opportunity (DPO), Defects per unit (DPU) and Yield, a new algorithm ba...

This paper analyzes renewal input state dependent queue with $N$- policy wherein the server takes exactly one vacation. Using the supplementary variable technique and recursive method, we derive the steady state system length distributions at various epochs. Various performance measures has been presented. Finally, some numerical  computations in the form of graphs are presented to show the par...

Notations. Let λ be the base measure over ∆n given by the uniform random variable (say U ) over ∆n. Hence, for all measurable A ⊆ ∆n, λ(A) = P(U ∈ A). Also, η : X→∆n is the mapping that gives the conditional probability vector η(x) = [P(Y = 1 |X = x), . . . ,P(Y = n |X = x)]> ∈ ∆n for a given instance x ∈ X . Let ν be the probability measure over the simplex induced by the random variable η(X);...
