Based on standard procedures used in optometry clinics, we compare measurements of visual acuity for 10 subjects (11 eyes tested) in the presence of natural ocular aberrations and different degrees of induced defocus, with the predictions given by a Bayesian model customized with aberrometric data of the eye. The absolute predictions of the model, without any adjustment, show good agreement wit...

The use of team for teaching programming can be effective in the classroom because it helps students to generate and acquire new knowledge in less time, but these groups to be formed without taking into account some respects, may cause an adverse effect on the teaching-learning process. This paper proposes a tool for the formation of team based on the semantics of source code (SOFORG). This sem...

BACKGROUND Anesthesiology residencies are developing trainee assessment tools to evaluate 25 milestones that map to the six core competencies. The effort will be facilitated by development of automated methods to capture, assess, and report trainee performance to program directors, the Accreditation Council for Graduate Medical Education and the trainees themselves. METHODS The authors levera...

Strategic goals are of no use if you can’t tell whether they have been accomplished. A measurement program is an essential element in the strategic arsenal. In this month’s issue of Strategic Software Engineering, I will explore some issues about measurement and effective strategic metrics. I will discuss some specific metrics but also how to setup a measurement program that addresses your needs.

PROBLEM Academic physician reimbursement has moved to productivity-based compensation plans. To be sustainable, such plans must be self-funding. Additionally, unless research and education are appropriately valued, faculty involved in these efforts will become disillusioned, yet revenue generation in these activities is less robust than for clinical care activities. APPROACH Faculty at the De...

Colonoscopy is a frequently performed diagnostic and therapeutic test and the primary screening tool in several nationalized bowel cancer screening programs. There has been a considerable focus on maximizing the utility of colonoscopy. This has occurred in four key areas: Optimizing patient selection to reduce unnecessary or low yield colonoscopy has offered cost-benefit improvements in populat...

The Harvard community has made this article openly available. Please share how this access benefits you. Your story matters. Background: Surgical site infection (SSI) rates are publicly reported as quality metrics and increasingly used to determine financial reimbursement.

In this paper we propose a tool that compares the difference of the surface and its simplified representation. Geometry-based metrics usually cannot truly reflect how the user perceives the difference when surfaces are rendered on the screen, hence we provide an alternative tool that is image-based, which complement the deficiency of the geometry-based. Two metrics are implemented in the tool: ...

There are differences in sleep duration between Blacks/African-Americans and Whites/European-Americans. Recently, we found differences between these ancestry groups in the circadian system, such as circadian period and the magnitude of phase shifts. Here we document the role of ancestry on sleep and cognitive performance before and after a 9-h advance in the sleep/wake schedule similar to flyin...
