Few studies have evaluated the reliability of lifetime sun exposure estimated from inquiring about the number of hours people spent outdoors in a given period on a typical weekday or weekend day (the time-based approach). Some investigations have suggested that women have a particularly difficult task in estimating time outdoors in adulthood due to their family and occupational roles. We hypoth...

BACKGROUND AND OBJECTIVES Encouraging student engagement in the large-classroom setting can be difficult. Challenges include the depersonalized nature of the environment and the fact that students frequently find asking questions and participating in class discussion intimidating. Social media has the potential to address these barriers, but this has not yet been formally evaluated. Our study a...

PURPOSE The two pencil test (TPT) checks the ability to perform a simple visual-motor task. The test is only partially based on intact stereopsis, since monocular depth perception clues are involved. To overcome this shortcoming, a new test variant has been developed and tested. METHODS By covering the tip of the examiner's rod, monocular cues should be drastically reduced. Twenty normal subj...

BACKGROUND AND PURPOSE The Harris Infant Neuromotor Test (HINT) is a screening tool designed to identify neuromotor or cognitive/behavioral concerns in infants who are healthy or at high risk between the ages of 3 and 12 months. The purpose of this study was to determine whether the HINT could distinguish between infants at high risk and infants at low risk for neuromotor delays. SUBJECTS AND...

The calculation of the heart axis in the frontal plane can be performed with the combination of any two leads. The use of combination of bipolar (I, II, III) and unipolar leads (aVR, aVL and aVF) can produce wrong results. Calculation of the electrical axis from leads I and aVF without correction (sometimes used in ECG recorders): EA= Arctan (aVF/I) results in lower values (in our study: 34 4 ,...

Empirical tests are used to help determine whether a given sequence of numbers has statistical properties similar to those of a sequence whose elements are drawn from a uniform probability distribution. The runs test and the maximum of t test are two traditional tests that have been applied to sequences of real numbers between 0 and 1. Motivated by the desire for a set of empirical tests that a...
