While the Periotest continues to be used in assessing the integrity of implants, there are numerous reports of its inconsistencies. To understand more precisely what the Periotest is actually measuring, a mathematical model was developed that illustrates the effect that various geometric and clinical parameters have on the Periotest value (PTV). In addition, the model was validated with an in v...

According to the International Classification of Functioning, Disability and Health model endorsed by the World Health Organization, activity (the execution of a task or action by an individual), and participation (involvement in a life situation) are important components in the assessment of health and functioning of an individual. The purpose of this study was to compare the activity performa...

PURPOSE To develop and test the psychometric properties of a parent-reported questionnaire measuring participation of preschool children (Children Participation Questionnaire; CPQ) aged 4-6 years in their everyday activities. METHODS Reliability was tested by Cronbach's alpha and by test-retest. Construct validity was computed by known group differences analysis. Convergent and divergent vali...

Microarrays provide a promising tool for the diagnosis of cancers on a molecular level. However, due to the large dimensions and the intrinsic variations of such data, feature selection that reduces the data to a small number of “informative genes” is important before any discriminant analysis based on such data. Many marginal statistical measures have been applied to gene expression data despi...

the purpose of the present study is to develop appropriate scoring scales for each of the defined stages of the writing process, and also to determine to what extent these scoring scales can reliably and validly assess the performances of efl learners in an academic writing task. two hundred and two students’ writing samples were collected after a step-by-step process oriented essay writing ins...

In Parkinson's disease (PD) rating scales are used to assess the degree of disease-related disability and to titrate long-term treatment to each phase of the disease. Recognition of nonmotor symptoms required modification of existing widely used scales to integrate nonmotor elements. In addition, new scales have been developed for the assessment of nonmotor symptoms. In this article, assessment...

This article reviews recent progress in observational determination of the properties of dark matter on small astrophysical scales, and progress towards the European Extremely Large Telescope. Current results suggest some surprises: the central DM density profile is typically cored, not cusped, with scale sizes never less than a few hundred pc; the central densities are typically 10 − 20GeV/cc;...

Human stereo vision can resolve remarkably small depth differences between two stimuli, but the smallest resolvable difference is usually that between stimuli located near the plane of fixation. As distance from this plane increases, so does the smallest detectable increment in disparity. We examined this loss of resolution by comparing disparity discrimination thresholds for single-scale and m...

images as well. Their presentation material (slides) must be clear and easily interpretable. While some ‘glitz’ is good, too much detracts from the message.” Last, when preparing a conference, look at your slides as if you are sitting in the audience. What looks good on the small screen may not look that good on the big one. Many thanks to my colleagues quoted above for taking time to answer my...

In contemporary clinical practice and research, many different instruments are used to measure depression severity. Santor et al. [1] identified no fewer than 280 scales developed in the last century, many of which are still in use. The responsiveness of these various depression scales to treatmentdand the comparison of responsiveness among scalesdhas become an important research topic. Respons...
